She married László Radványi, also known as Johann Lorenz Schmidt, a Hungarian Communist in 1925, thereby acquiring Hungarian citizenship. In Cologne and Heidelberg she studied history, the history of art and Chinese. She joined the Communist Party of Germany in 1928, at a time when the Weimar Republic was moribund and soon to be replaced. Her 1932 novel, \"Die Gefährten\" was a prophetic warning of the dangers of Nazism, which led to her being arrested by the Gestapo. In 1932, she also formally left the Jewish community. By 1934 she had emigrated, via Zurich, to Paris. After German troops invaded the French Third Republic in 1940, she fled to Marseilles and one year later to Mexico, where she founded the anti-fascist 'Heinrich-Heine-Klub', named after the German Jewish poet Heinrich Heine, and founded \"Freies Deutschland\" (\"Free Germany\"), an academic journal. While still in Paris, in 1939, she had written \"The Seventh Cross\", for which she received the Büchner-Prize in 1947. The novel is set in 1936 and describes the escape of seven prisoners from a concentration camp. It was published in the United States in 1942 and produced as a movie in 1944 by MGM starring Spencer Tracy. \"The Seventh Cross\" was one of the very few depictions of Nazi concentration camps, in either literature or the cinema, during World War II. Seghers's best-known story, \"The Outing of the Dead Girls\" (1946), written in Mexico, was an autobiographical reminiscence of a pre-World War I class excursion on the Rhine river in which the actions of the protagonist's classmates are seen in light of their decisions and ultimate fates during both world wars. In describing them, the German countryside, and her soon-to-be destroyed hometown Mainz, Seghers gives the reader a strong sense of lost innocence and the senseless injustices of war, from which there proves to be no escape, whether or not you sympathized with the NSDAP. Other notable Seghers stories include \"Sagen von Artemis\" (1938) and \"The Ship of the Argonauts\" (1953), both based on myths. In 1947, Seghers returned to Germany, moved to West Berlin, and became a member of the SED in the zone occupied by the Soviets and received Georg Büchner Prize in the same year. In 1950, she moved to East Berlin and became a co-founder of the Academy of the Arts of the GDR and became a member of World Peace Council. In 1951, she received the first Nationalpreis der DDR, the Stalin Peace Prize also in 1951, and an honorary doctorate by the University of Jena in 1959.

Jean-Jacques Ampère, a successful merchant, was an admirer of the philosophy of Jean-Jacques Rousseau, whose theories of education (as outlined in his treatise Émile) were the basis of Ampère's education. Rousseau believed that young boys should avoid formal schooling and pursue instead an \"education direct from nature.\" Ampère's father actualized this ideal by allowing his son to educate himself within the walls of his well-stocked library. French Enlightenment masterpieces such as Georges-Louis Leclerc, comte de Buffon's \"Histoire naturelle, générale et particulière\" (begun in 1749) and Denis Diderot and Jean le Rond d'Alembert's \"Encyclopédie\" (volumes added between 1751 and 1772) thus became Ampère's schoolmasters.

In later life Ampère claimed that he knew as much about, mathematics and science when he was eighteen as ever he knew; but, a polymath, his reading embraced history, travels, poetry, philosophy, and the natural sciences. His mother was a devout woman, so Ampère was also initiated into the Catholic faith along with Enlightenment science. The French Revolution (1789–99) that began during his youth was also influential: Ampère's father was called into public service by the new revolutionary government, becoming a justice of the peace in a small town near Lyon. When the Jacobin faction seized control of the Revolutionary government in 1792, his father Jean-Jacques Ampère resisted the new political tides, and he was guillotined on 24 November 1793, as part of the Jacobin purges of the period. In 1796 Ampère met Julie Carron, and in 1799 they were married. André-Marie Ampère took his first regular job in 1799 as a mathematics teacher, which gave him the financial security to marry Carron and father his first child, Jean-Jacques (named after his father), the next year. (Jean-Jacques Ampère eventually achieved his own fame as a scholar of languages.) Ampère's maturation corresponded with the transition to the Napoleonic regime in France, and the young father and teacher found new opportunities for success within the technocratic structures favoured by the new French First Consul. In 1802 Ampère was appointed a professor of physics and chemistry at the École Centrale in Bourg-en-Bresse, leaving his ailing wife and infant son Jean-Jacques Antoine Ampère in Lyon.

As well as holding positions at this school until 1828, in 1819 and 1820 Ampère offered courses in philosophy and astronomy, respectively, at the University of Paris, and in 1824 he was elected to the prestigious chair in experimental physics at the Collège de France. In 1814 Ampère was invited to join the class of mathematicians in the new \"Institut Impérial\", the umbrella under which the reformed state Academy of Sciences would sit. Ampère engaged in a diverse array of scientific inquiries during the years leading up to his election to the academy—writing papers and engaging in topics from mathematics and philosophy to chemistry and astronomy, which was customary among the leading scientific intellectuals of the day. Ampère claimed that \"at eighteen years he found three culminating points in his life, his First Communion, the reading of Antoine Leonard Thomas's \"Eulogy of Descartes\", and the Taking of the Bastille.

Ampère began developing a mathematical and physical theory to understand the relationship between electricity and magnetism. Furthering Ørsted's experimental work, Ampère showed that two parallel wires carrying electric currents attract or repel each other, depending on whether the currents flow in the same or opposite directions, respectively - this laid the foundation of electrodynamics. He also applied mathematics in generalizing physical laws from these experimental results. The most important of these was the principle that came to be called Ampère's law, which states that the mutual action of two lengths of current-carrying wire is proportional to their lengths and to the intensities of their currents. Ampère also applied this same principle to magnetism, showing the harmony between his law and French physicist Charles Augustin de Coulomb's law of magnetic action. Ampère's devotion to, and skill with, experimental techniques anchored his science within the emerging fields of experimental physics. Ampère also provided a physical understanding of the electromagnetic relationship, theorizing the existence of an \"electrodynamic molecule\" (the forerunner of the idea of the electron) that served as the component element of both electricity and magnetism. Using this physical explanation of electromagnetic motion, Ampère developed a physical account of electromagnetic phenomena that was both empirically demonstrable and mathematically predictive. In 1827 Ampère published his magnum opus, \"Mémoire sur la théorie mathématique des phénomènes électrodynamiques uniquement déduite de l’experience\" (Memoir on the Mathematical Theory of Electrodynamic Phenomena, Uniquely Deduced from Experience), the work that coined the name of his new science, \"electrodynamics\", and became known ever after as its founding treatise.

He equated homogeneous (redundant) skills to \"mechanical solidarity\" whose inertia retarded adaptation. He contrasted this with the self-regulating behaviour of a division of labour based on differences in constituency, equated to \"organic solidarity\", whose lack of inertia made it sensitive to needed changes. Durkheim observed that the conflict between the evolved organic division of labour and the homogeneous mechanical type was such that one could not exist in the presence of the other. When solidarity is organic, anomie is impossible. Sensitivity to mutual needs promotes evolution in the division of labour. \"Producers, being near consumers, can easily reckon the extent of the needs to be satisfied. Equilibrium is established without any trouble and production regulates itself.\" Durkheim contrasted the condition of anomie as being the result of a malfunction of organic solidarity after the transition to mechanical solidarity: Durkheim's use of the term anomie was about the phenomenon of industrialization—mass-regimentation that could not adapt due to its own inertia—its resistance to change, which causes disruptive cycles of collective behavior e.g. economics, due to the necessity of a prolonged buildup of sufficient force or momentum to overcome the inertia. Later in 1897, in his studies of suicide, Durkheim associated anomie to the influence of a lack of norms or norms that were too rigid. But such normlessness or norm-rigidity was a \"symptom of anomie\", caused by the lack of differential adaptation that would enable norms to evolve naturally due to self-regulation, either to develop norms where none existed or to change norms that had become rigid and obsolete. In 1938 Robert K. Merton linked anomie with deviance and argued that the discontinuity between culture and structure have the dysfunctional consequence of leading to deviance within society. He described 5 types of deviance in terms of the acceptance or rejection of social goals and the institutionalized means of achieving them.", "section_level": 1}, {"title": "Etymology.", "content": "The word, \"a reborrowing with French spelling of \"anomy\"\", comes from Greek \"lawlessness\", namely the privative alpha prefix (\"a-\" \"without\"), and \"nomos\" \"law\". The Greeks distinguished between \"nomos\" (, \"law\"), and \"arché\" (, \"starting rule, axiom, principle\"). For example, a monarch is a single ruler but he may still be subject to, and not exempt from, the prevailing laws, i.e. \"nomos\". In the original city state democracy, the majority rule was an aspect of \"arché\" because it was a rule-based, customary system, which might or might not make laws, i.e. \"nomos\". Thus, the original meaning of \"anomie\" defined anything or anyone against or outside the law, or a condition where the current laws were not applied resulting in a state of illegitimacy or lawlessness. The contemporary English understanding of the word \"anomie\" can accept greater flexibility in the word \"norm\", and some have used the idea of normlessness to reflect a similar situation to the idea of anarchy. But, as used by Émile Durkheim and later theorists, \"anomie\" is a reaction against or a retreat from the regulatory social controls of society, and is a completely separate concept from anarchy, which consists of the absence of the roles of rulers and submitted.", "section_level": 1}, {"title": "Social disorder.", "content": "The nineteenth century French pioneer sociologist Émile Durkheim borrowed the word from French philosopher Jean-Marie Guyau and used it in his influential book \"Suicide\" (1897), outlining the social (and not individual) causes of suicide, characterized by a rapid change of the standards or values of societies (often erroneously referred to as normlessness), and an associated feeling of alienation and purposelessness. He believed that \"anomie\" is common when the surrounding society has undergone significant changes in its economic fortunes, whether for better or for worse and, more generally, when there is a significant discrepancy between the ideological theories and values commonly professed and what was actually achievable in everyday life. This was contrary to previous theories on suicide which generally maintained that suicide was precipitated by negative events in a person's life and their subsequent depression. In Durkheim's view, traditional religions often provided the basis for the shared values which the anomic individual lacks. Furthermore, he argued that the division of labor that had been prevalent in economic life since the Industrial Revolution led individuals to pursue egoistic ends rather than seeking the good of a larger community. Robert King Merton also adopted the idea of anomie to develop strain theory, defining it as the discrepancy between common social goals and the legitimate means to attain those goals. In other words, an individual suffering from anomie would strive to attain the common goals of a specific society yet would not be able to reach these goals legitimately because of the structural limitations in society. As a result, the individual would exhibit deviant behavior. Friedrich Hayek notably uses the word \"anomie\" with this meaning. According to one academic survey, psychometric testing confirmed a link between anomie and academic dishonesty among university students, suggesting that universities needed to foster codes of ethics among students in order to curb it. In another study, anomie was seen as a \"push factor\" in tourism. As an older variant, the 1913 \"Webster's Dictionary\" reports use of the word \"anomie\" as meaning \"disregard or violation of the law\" but anomie as a social disorder is not to be confused with anarchy. Proponents of anarchism claim that anarchy does not necessarily lead to anomie and that hierarchical command actually increases lawlessness.

At that time, the law allowed the elder Dumas to take the child away from his mother. Her agony inspired the younger Dumas to write about tragic female characters. In almost all of his writings, he emphasized the moral purpose of literature; in his play \"The Illegitimate Son\" (1858) he espoused the belief that if a man fathers an illegitimate child, then he has an obligation to legitimize the child and marry the woman (see Illegitimacy in fiction). At boarding schools, he was constantly taunted by his classmates because of his family situation. These issues profoundly influenced his thoughts, behaviour, and writing. Dumas' paternal great-grandparents were Marquis Alexandre-Antoine Davy de la Pailleterie, a French nobleman and \"Général commissaire\" in the Artillery in the colony of Saint-Domingue—now Haiti—and Marie-Cessette Dumas, an African slave. Their son Thomas-Alexandre Dumas became a high-ranking general of Revolutionary France. In 1844, Dumas moved to Saint-Germain-en-Laye, near Paris, to live with his father. There he met Marie Duplessis, a young courtesan who would be the inspiration for the character Marguerite Gauthier in his romantic novel \"La Dame aux camélias\" (\"The Lady of the Camellias\"). Adapted into a play, it was titled \"Camille\" in English and became the basis for Verdi's 1853 opera, \"La traviata\", Duplessis undergoing yet another name change, this time to Violetta Valéry. Although he admitted that he had done the adaptation because he needed the money, he had great success with the play, which started his career as a dramatist. He was not only more renowned than his father during his lifetime, but also dominated the serious French stage for most of the second half of the 19th century. After this, he virtually abandoned writing novels, though his semi-autobiographical \"L'Affaire Clemenceau\" (1867) achieved some solid success.

Ascorbic acid is prepared in industry from glucose in a method based on the historical Reichstein process. In the first of a five-step process, glucose is catalytically hydrogenated to sorbitol, which is then oxidized by the microorganism \"Acetobacter suboxydans\" to sorbose. Only one of the six hydroxy groups is oxidized by this enzymatic reaction. From this point, two routes are available. Treatment of the product with acetone in the presence of an acid catalyst converts four of the remaining hydroxyl groups to acetals. The unprotected hydroxyl group is oxidized to the carboxylic acid by reaction with the catalytic oxidant TEMPO (regenerated by sodium hypochlorite — bleaching solution). Historically, industrial preparation via the Reichstein process used potassium permanganate as the bleaching solution. Acid-catalyzed hydrolysis of this product performs the dual function of removing the two acetal groups and ring-closing lactonization. This step yields ascorbic acid. Each of the five steps has a yield larger than 90%. A more biotechnological process, first developed in China in the 1960s, but further developed in the 1990s, bypasses the use of acetone-protecting groups. A second genetically modified microbe species, such as mutant \"Erwinia\", among others, oxidises sorbose into 2-ketogluconic acid (2-KGA), which can then undergo ring-closing lactonization via dehydration. This method is used in the predominant process used by the ascorbic acid industry in China, which supplies 80% of world's ascorbic acid. American and Chinese researchers are competing to engineer a mutant that can carry out a one-pot fermentation directly from glucose to 2-KGA, bypassing both the need for a second fermentation and the need to reduce glucose to sorbitol. There exists a -ascorbic acid, which does not occur in nature but can be synthesized artificially. To be specific, -ascorbate is known to participate in many specific enzyme reactions that require the correct enantiomer (-ascorbate and not -ascorbate). -Ascorbic acid has a specific rotation of [α] = +23°.", "section_level": 2}, {"title": "Determination.", "content": "The traditional way to analyze the ascorbic acid content is the process of titration with an oxidizing agent, and several procedures have been developed. The popular iodometry approach uses iodine in the presence of a starch indicator.

This indicates the end-point of the titration. As an alternative, ascorbic acid can be treated with iodine in excess, followed by back titration with sodium thiosulfate using starch as an indicator. This iodometric method has been revised to exploit reaction of ascorbic acid with iodate and iodide in acid solution. Electrolyzing the solution of potassium iodide produces iodine, which reacts with ascorbic acid. The end of process is determined by potentiometric titration in a manner similar to Karl Fischer titration. The amount of ascorbic acid can be calculated by Faraday's law. Another alternative uses \"N\"-bromosuccinimide (NBS) as the oxidizing agent, in the presence of potassium iodide and starch.

It is a deliberate respelling of \"bite\" to avoid accidental mutation to \"bit\". Another origin of \"byte\" for bit groups smaller than a computers's word size, and in particular groups of four bits, is on record by Louis G. Dooley, who claimed he coined the term while working with Jules Schwartz and Dick Beeler on an air defense system called SAGE at MIT Lincoln Laboratory in 1956 or 1957, which was jointly developed by Rand, MIT, and IBM. Later on, Schwartz's language JOVIAL actually used the term, but the author recalled vaguely that it was derived from AN/FSQ-31. Early computers used a variety of four-bit binary-coded decimal (BCD) representations and the six-bit codes for printable graphic patterns common in the U.S. Army (FIELDATA) and Navy. These representations included alphanumeric characters and special graphical symbols. These sets were expanded in 1963 to seven bits of coding, called the American Standard Code for Information Interchange (ASCII) as the Federal Information Processing Standard, which replaced the incompatible teleprinter codes in use by different branches of the U.S. government and universities during the 1960s. ASCII included the distinction of upper- and lowercase alphabets and a set of control characters to facilitate the transmission of written language as well as printing device functions, such as page advance and line feed, and the physical or logical control of data flow over the transmission media. During the early 1960s, while also active in ASCII standardization, IBM simultaneously introduced in its product line of System/360 the eight-bit Extended Binary Coded Decimal Interchange Code (EBCDIC), an expansion of their six-bit binary-coded decimal (BCDIC) representations used in earlier card punches. The prominence of the System/360 led to the ubiquitous adoption of the eight-bit storage size, while in detail the EBCDIC and ASCII encoding schemes are different. In the early 1960s, AT&T introduced digital telephony on long-distance trunk lines. These used the eight-bit μ-law encoding. This large investment promised to reduce transmission costs for eight-bit data. The development of eight-bit microprocessors in the 1970s popularized this storage size. Microprocessors such as the Intel 8008, the direct predecessor of the 8080 and the 8086, used in early personal computers, could also perform a small number of operations on the four-bit pairs in a byte, such as the decimal-add-adjust (DAA) instruction. A four-bit quantity is often called a nibble, also \"nybble\", which is conveniently represented by a single hexadecimal digit. The term \"octet\" is used to unambiguously specify a size of eight bits. It is used extensively in protocol definitions. Historically, the term \"octad\" or \"octade\" was used to denote eight bits as well at least in Western Europe; however, this usage is no longer common.

In the International System of Quantities (ISQ), B is the symbol of the \"bel\", a unit of logarithmic power ratios named after Alexander Graham Bell, creating a conflict with the IEC specification. However, little danger of confusion exists, because the bel is a rarely used unit. It is used primarily in its decadic fraction, the decibel (dB), for signal strength and sound pressure level measurements, while a unit for one tenth of a byte, the decibyte, and other fractions, are only used in derived units, such as transmission rates.

The C standard requires that the integral data type \"unsigned char\" must hold at least 256 different values, and is represented by at least eight bits (clause 5.2.4.2.1). Various implementations of C and C++ reserve 8, 9, 16, 32, or 36 bits for the storage of a byte. In addition, the C and C++ standards require that there are no gaps between two bytes. This means every bit in memory is part of a byte. Java's primitive codice_1 data type is always defined as consisting of 8 bits and being a signed data type, holding values from −128 to 127. .NET programming languages, such as C#, define both an unsigned codice_1 and a signed codice_3, holding values from 0 to 255, and −128 to 127, respectively. In data transmission systems, the byte is defined as a contiguous sequence of bits in a serial data stream representing the smallest distinguished unit of data.

The entries are now known to be 39 galaxies, 4 planetary nebulae, 7 other types of nebulae, and 55 star clusters. Messier did his observing with a 100 mm (four-inch) refracting telescope from Hôtel de Cluny (now the Musée national du Moyen Âge), in downtown Paris, France.

The APA manual of style requires \"data\" to be plural.", "section_level": 1}, {"title": "Meaning.", "content": "Data, information, knowledge and wisdom are closely related concepts, but each has its own role in relation to the other, and each term has its own meaning. According to a common view, data is collected and analyzed; data only becomes information suitable for making decisions once it has been analyzed in some fashion. One can say that the extent to which a set of data is informative to someone depends on the extent to which it is unexpected by that person. The amount of information contained in a data stream may be characterized by its Shannon entropy. Knowledge is the understanding based on extensive experience dealing with information on a subject. For example, the height of Mount Everest is generally considered data. The height can be measured precisely with an altimeter and entered into a database. This data may be included in a book along with other data on Mount Everest to describe the mountain in a manner useful for those who wish to make a decision about the best method to climb it. An understanding based on experience climbing mountains that could advise persons on the way to reach Mount Everest's peak may be seen as \"knowledge\". The practical climbing of Mount Everest's peak based on this knowledge may be seen as \"wisdom\". In other words, wisdom refers to the practical application of a person's knowledge in those circumstances where good may result. Thus wisdom complements and completes the series \"data\", \"information\" and \"knowledge\" of increasingly abstract concepts. Data is often assumed to be the least abstract concept, information the next least, and knowledge the most abstract. In this view, data becomes information by interpretation; e.g., the height of Mount Everest is generally considered \"data\", a book on Mount Everest geological characteristics may be considered \"information\", and a climber's guidebook containing practical information on the best way to reach Mount Everest's peak may be considered \"knowledge\". \"Information\" bears a diversity of meanings that ranges from everyday usage to technical use. This view, however, has also been argued to reverse the way in which data emerges from information, and information from knowledge. Generally speaking, the concept of information is closely related to notions of constraint, communication, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, and representation. Beynon-Davies uses the concept of a sign to differentiate between data and information; data is a series of symbols, while information occurs when the symbols are used to refer to something. Before the development of computing devices and machines, people had to manually collect data and impose patterns on it. Since the development of computing devices and machines, these devices can also collect data. In the 2010s, computers are widely used in many fields to collect data and sort or process it, in disciplines ranging from marketing, analysis of social services usage by citizens to scientific research. These patterns in data are seen as information which can be used to enhance knowledge. These patterns may be interpreted as \"truth\" (though \"truth\" can be a subjective concept), and may be authorized as aesthetic and ethical criteria in some disciplines or cultures. Events that leave behind perceivable physical or virtual remains can be traced back through data. Marks are no longer considered data once the link between the mark and observation is broken. Mechanical computing devices are classified according to the means by which they represent data. An analog computer represents a datum as a voltage, distance, position, or other physical quantity. A digital computer represents a piece of data as a sequence of symbols drawn from a fixed alphabet. The most common digital computers use a binary alphabet, that is, an alphabet of two characters, typically denoted \"0\" and \"1\". More familiar representations, such as numbers or letters, are then constructed from the binary alphabet. Some special forms of data are distinguished. A computer program is a collection of data, which can be interpreted as instructions. Most computer languages make a distinction between programs and the other data on which programs operate, but in some languages, notably Lisp and similar languages, programs are essentially indistinguishable from other data. It is also useful to distinguish metadata, that is, a description of other data.

The latter offers an articulate method of collecting, classifying and analyzing data using five possible angles of analysis (at least three) in order to maximize the research's objectivity and permit an understanding of the phenomena under investigation as complete as possible: qualitative and quantitative methods, literature reviews (including scholarly articles), interviews with experts, and computer simulation.

JavaScript was released by Netscape Communications in 1995 within Netscape Navigator 2.0. Netscape's competitor, Microsoft, released Internet Explorer 3.0 the following year with a reimplementation of JavaScript called JScript. JavaScript and JScript let web developers create web pages with client-side interactivity. The limited facilities for detecting user-generated events and modifying the HTML document in the first generation of these languages eventually became known as \"DOM Level 0\" or \"Legacy DOM.\" No independent standard was developed for DOM Level 0, but it was partly described in the specifications for HTML 4. Legacy DOM was limited in the kinds of elements that could be accessed. Form, link and image elements could be referenced with a hierarchical name that began with the root document object. A hierarchical name could make use of either the names or the sequential index of the traversed elements. For example, a form input element could be accessed as either codice_1 or codice_2. The Legacy DOM enabled client-side form validation and the popular \"rollover\" effect. In 1997, Netscape and Microsoft released version 4.0 of Netscape Navigator and Internet Explorer respectively, adding support for Dynamic HTML (DHTML) functionality enabling changes to a loaded HTML document. DHTML required extensions to the rudimentary document object that was available in the Legacy DOM implementations. Although the Legacy DOM implementations were largely compatible since JScript was based on JavaScript, the DHTML DOM extensions were developed in parallel by each browser maker and remained incompatible. These versions of the DOM became known as the \"Intermediate DOM.\" After the standardization of ECMAScript, the W3C DOM Working Group began drafting a standard DOM specification. The completed specification, known as \"DOM Level 1\", became a W3C Recommendation in late 1998.

They met through the Königliche Technische Hochschule (technical university) of Dresden, where Kirchner and Bleyl began studying in 1901 and became close friends in their first term. They discussed art together and also studied nature, having a radical outlook in common. Kirchner continued studies in Munich 1903–1904, returning to Dresden in 1905 to complete his degree. The institution provided a wide range of studies in addition to architecture, such as freehand drawing, perspective drawing and the historical study of art. The name \"Die Brücke\" was intended to \"symbolize the link, or bridge, they would form with art of the future\". Die Brücke aimed to eschew the prevalent traditional academic style and find a new mode of artistic expression, which would form a bridge (hence the name) between the past and the present. They responded both to past artists such as Albrecht Dürer, Matthias Grünewald and Lucas Cranach the Elder, as well as contemporary international avant-garde movements. The group published a broadside called \"Programme\" in 1906, where Kirchner wrote: As part of the affirmation of their national heritage, they revived older media, particularly woodcut prints. The group developed a common style based on vivid color, emotional tension, violent imagery, and an influence from primitivism. After first concentrating exclusively on urban subject matter, the group ventured into southern Germany on expeditions arranged by Mueller and produced more nudes and arcadian images. They invented the printmaking technique of linocut, although they at first described them as traditional woodcuts, which they also made. The group members initially \"isolated\" themselves in a working-class neighborhood of Dresden, aiming thereby to reject their own bourgeois backgrounds. Erich Heckel was able to obtain an empty butcher's shop on the Berlinerstrasse in Friedrichstadt for their use as a studio. Bleyl described the studio as: Kirchner's became a venue which overthrew social conventions to allow casual love-making and frequent nudity. Group life-drawing sessions took place using models from the social circle, rather than professionals, and choosing quarter-hour poses to encourage spontaneity. Bleyl described one such model, Isabella, a fifteen-year-old girl from the neighbourhood, as \"a very lively, beautifully built, joyous individual, without any deformation caused by the silly fashion of the corset and completely suitable to our artistic demands, especially in the blossoming condition of her girlish buds.\" The group composed a manifesto (mostly Kirchner's work), which was carved on wood and asserted a new generation, \"who want freedom in our work and in our lives, independence from older, established forces.\" In September and October 1906, the first group exhibition was held, focused on the female nude, in the showroom of K.F.M. Seifert and Co. in Dresden. Emil Nolde (1867–1956) and Max Pechstein (1881–1955) joined the group in 1906. Bleyl married in 1907, and, with a concern to support his family, left the group. Otto Mueller (1874–1930) joined in 1910. Between 1907 and 1911, Brücke members stayed during the summer at the Moritzburg lakes and on the island of Fehmarn.

Their leaves are of variable size and alternately arranged, or with the upper leaves becoming nearly opposite. The leaves may be petiolate or sessile. There are no stipules but the petioles are frequently sheathing and the leaves may be perfoliate. The leaf blade is usually dissected, ternate or pinnatifid, but simple and entire in some genera, e.g. \"Bupleurum\". Commonly, their leaves emit a marked smell when crushed, aromatic to foetid, but absent in some species. The defining characteristic of this family is the inflorescence, the flowers nearly always aggregated in terminal umbels, that may be simple or more commonly compound, often umbelliform cymes. The flowers are usually perfect (hermaphroditic) and actinomorphic, but there may be zygomorphic flowers at the edge of the umbel, as in carrot (\"Daucus carota\") and coriander, with petals of unequal size, the ones pointing outward from the umbel larger than the ones pointing inward. Some are andromonoecious, polygamomonoecious, or even dioecious (as in \"Acronema\"), with a distinct calyx and corolla, but the calyx is often highly reduced, to the point of being undetectable in many species, while the corolla can be white, yellow, pink or purple. The flowers are nearly perfectly pentamerous, with five petals, sepals, and stamens. The androecium consists of five stamens, but there is often variation in the functionality of the stamens even within a single inflorescence.

He is mentioned by name, though rarely, by other Greek mathematicians from Archimedes (c. 287 BC – c. 212 BC) onward, and is usually referred to as \"ὁ στοιχειώτης\" (\"the author of Elements\"). The few historical references to Euclid were written by Proclus c. 450 AD, centuries after Euclid lived. A detailed biography of Euclid is given by Arabian authors, mentioning, for example, a birth town of Tyre. This biography is generally believed to be fictitious. If he came from Alexandria, he would have known the Serapeum of Alexandria, and the Library of Alexandria, and may have worked there during his time. Euclid's arrival in Alexandria came about ten years after its founding by Alexander the Great, which means he arrived c. 322 BC. Proclus introduces Euclid only briefly in his \"Commentary on the Elements\". According to Proclus, Euclid supposedly belonged to Plato's \"persuasion\" and brought together the \"Elements\", drawing on prior work of Eudoxus of Cnidus and of several pupils of Plato (particularly Theaetetus and Philip of Opus.) Proclus believes that Euclid is not much younger than these, and that he must have lived during the time of Ptolemy I (c. 367 BC – 282 BC) because he was mentioned by Archimedes. Although the apparent citation of Euclid by Archimedes has been judged to be an interpolation by later editors of his works, it is still believed that Euclid wrote his works before Archimedes wrote his. Proclus later retells a story that, when Ptolemy I asked if there was a shorter path to learning geometry than Euclid's \"Elements\", \"Euclid replied there is no royal road to geometry.\" This anecdote is questionable since it is similar to a story told about Menaechmus and Alexander the Great. Euclid died c. 270 BC, presumably in Alexandria. In the only other key reference to Euclid, Pappus of Alexandria (c. 320 AD) briefly mentioned that Apollonius \"spent a very long time with the pupils of Euclid at Alexandria, and it was thus that he acquired such a scientific habit of thought\" c. 247–222 BC. Because the lack of biographical information is unusual for the period (extensive biographies being available for most significant Greek mathematicians several centuries before and after Euclid), some researchers have proposed that Euclid was not a historical personage, and that his works were written by a team of mathematicians who took the name Euclid from Euclid of Megara (à la Bourbaki).

In 1909, Frenchman Armand Zipfel made the first flight demonstration in Tempelhof, followed by Orville Wright later that same year. Tempelhof was first officially designated as an airport on 8 October 1923. Deutsche Luft Hansa was founded in Tempelhof on 6 January 1926. The old terminal, originally constructed in 1927, became the world's first with an underground railway. The station has since been renamed \"Paradestraße\", because the rebuilding of the airport in the 1930s required the airport access to be moved to a major intersection with a station now called Platz der Luftbrücke after the Berlin Airlift. As part of Albert Speer's plan for the reconstruction of Berlin during the Nazi era, Prof. Ernst Sagebiel was ordered to replace the old terminal with a new terminal building in 1934. The airport halls and the adjoining buildings, intended to become the gateway to Europe and a symbol of Hitler's \"world capital\" Germania, are still known as one of the largest built entities worldwide, and have been described by British architect Sir Norman Foster as \"the mother of all airports\". With its façades of shell limestone, the terminal building, built between 1936 and 1941, forms a 1.2 kilometre long quadrant. Arriving passengers walked through customs controls to the reception hall. Tempelhof was served by the U6 U-Bahn line along Mehringdamm and up Friedrichstraße (Platz der Luftbrücke station). Zentralflughafen Tempelhof-Berlin had the advantage of a central location just minutes from the Berlin city centre and quickly became one of the world's busiest airports. Tempelhof saw its greatest pre-war days during 1938–1939, when up to 52 foreign and 40 domestic flights arrived and departed daily from the old terminal while the new one was still under construction. The new air terminal was designed as headquarters for Deutsche Luft Hansa (moved in 1938), the German national airline at that time. As a forerunner of today's modern airports, the building was designed with many unique features, including giant arc-shaped aircraft hangars. Although under construction for more than ten years, it was never finished because of World War II. For passengers and freight, the 1927-built terminal stayed in use until 24 April 1945. The building complex was designed to resemble an eagle in flight with semicircular hangars forming the bird's spread wings.

On 29 April 1952, an Air France Douglas C-54A (registration F-BELI) operating a scheduled service from Frankfurt Rhein-Main Airport to Berlin Tempelhof came under sustained attack from two Soviet MiG 15 fighters while passing through one of the Allied air corridors over East Germany. Although the attack had severely damaged the plane, necessitating the shutdown of engines number three and four, the pilot in command of the aircraft managed to carry out a safe emergency landing at Tempelhof Airport. A subsequent inspection of the aircraft's damage at Tempelhof revealed that it had been hit by 89 shots fired from the Soviet MiGs during the preceding air attack. There were no fatalities among the 17 occupants (six crew, 11 passengers) despite the severity of the attack. The Soviet military authorities defended this attack on an unarmed civilian aircraft by claiming the Air France plane was outside the air corridor at the time of attack. On 19 January 1953, a Silver City Airways Bristol 170 Freighter Mark 21 (registration: G-AICM) operating a non-scheduled cargo flight from West Berlin crash-landed near Tempelhof Airport as a result of fuel starvation when bad weather at the destination forced it to return to Berlin. Although the accident damaged the aircraft beyond repair, both pilots survived. In 1978, LOT Polish Airlines flight 165 was hijacked and forced to land at Tempelhof. The US military authorities who were in charge of Tempelhof during the Cold War era arrested the East German hijacker on arrival. Following the hijacker's arrest, the US authorities returned the aircraft, its crew and those passengers who wished to resume their journey to Poland. In 1981, a LOT Polish Airlines Antonov AN-24 operating an internal scheduled service from Katowice to Gdańsk was hijacked en route and forced to land at Tempelhof.

Paulinus reached Fezzan and went further south. With the end of the Roman Empire and the following commercial crisis, Fezzan began to lose importance. The population was greatly reduced due to the desertification process of the Sahara during the early Middle Ages. During the 13th and 14th centuries, portions of Fezzan were part of the Kanem Empire. Wars against the Kanem–Bornu Empire in the early sixteenth century led to the founding of the Awlad Muhammad dynasty, with Murzuk becoming the capital of Fezzan. Around 1565 it was ruled by Muhammad ibn al-Muntasir. The Ottoman rulers of North Africa asserted their control over the region in the 17th century. In the reign of Abdulhamid II (1876–1909) Fezzan was used as a place of political exile for Young Turks because it was the most remote province from Istanbul. Beginning in 1911, Fezzan was occupied by Italy. However, Italy's control of the region was precarious until at least 1923, with the rise of the Benito Mussolini. The Italians were resisted in their early attempts at conquest by tribal Arab adherents to the militant Sanusiya Sufi religious order. The Tuareg clans of the region were only pacified by European expansion shortly before the Second World War, and some of them collaborated with the Italian Army in the North African Campaign. Free French troops occupied Murzuk, a chief town of Fezzan, on 16 January 1943, and proceeded to administer Fezzan with a staff stationed in Sabha, forming the Military Territory of Fezzan-Ghadames. French administration was largely exercised through Fezzan notables of the family of Sayf Al Nasr.

Traditionally, many of the headlines in the \"F.A.Z.\" were styled in orthodox blackletter format and no photographs appeared on the title page. Some of the rare exceptions were a picture of the celebrating people in front of the Reichstag in Berlin on German Unity Day on 4 October 1990, and the two pictures in the edition of 12 September 2001 showing the collapsing World Trade Center and the American president George W.

However, many of the settlers were not from Scandinavia, but descendants of Norse settlers in the Irish Sea region. In addition, women from Norse Ireland, Orkney, or Shetland often married native Scandinavian men before settling in the Faroe Islands and Iceland. As a result, the Irish language has had some influence on both Faroese and Icelandic. There is some debatable evidence of Irish language place names in the Faroes: for example, the names of Mykines, Stóra Dímun, Lítla Dímun and Argir have been hypothesized to contain Celtic roots. Other examples of early-introduced words of Celtic origin are: / (buttermilk), cf. Middle Irish ; (tail-piece of an animal), cf. Middle Irish ; (head, headhair), cf. Middle Irish ; (hand, paw), cf. Middle Irish ; (bull), cf. Middle Irish ; and (pasture in the outfield), cf. Middle Irish. Between the 9th and the 15th centuries, a distinct Faroese language evolved, although it was probably still mutually intelligible with Old West Norse, and remained similar to the Norn language of Orkney and Shetland during Norn's earlier phase. Faroese ceased to be a written language after the union of Norway with Denmark in 1380, with Danish replacing Faroese as the language of administration and education. The islanders continued to use the language in ballads, folktales, and everyday life. This maintained a rich spoken tradition, but for 300 years the language was not used in written form. In 1823 the Danish Bible Society published a diglot of the Gospel of Matthew, with Faroese on the left and Danish on the right. Venceslaus Ulricus Hammershaimb and the Icelandic grammarian and politician Jón Sigurðsson published a written standard for Modern Faroese in 1854, which still exists. They set a standard for the orthography of the language, based on its Old Norse roots and similar to that of Icelandic. The main purpose of this was for the spelling to represent the diverse dialects of Faroese in equal measure. Additionally, it had the advantages of being etymologically clear and keeping the kinship with the Icelandic written language. The actual pronunciation, however, often differs considerably from the written rendering. The letter \"ð\", for example, has no specific phoneme attached to it. Jakob Jakobsen devised a rival system of orthography, based on his wish for a phonetic spelling, but this system was never taken up by the speakers. In 1908 Scripture Gift Mission published the Gospel of John in Faroese. In 1937, Faroese replaced Danish as the official school language, in 1938 as the church language, and in 1948 as the national language by the Home Rule Act of the Faroes. However, Faroese did not become the common language of media and advertising until the 1980s. Today Danish is considered a foreign language, although around 5% of residents on the Faroes learn it as a first language, and it is taught in school from the first grade.

The language shares many features with both Old Icelandic and Old Norwegian; Old Norwegian appears closer to Old Faroese, whereas Old Icelandic remained rather archaic compared to other medieval varieties of Old West Norse. The most crucial aspects of the development of Faroese are diphthongisation and palatalisation. There is not enough data available to establish an accurate chronology of Faroese, but a rough one may be developed through comparison to the chronologies of Old Icelandic and Old Norwegian. In the 12th/13th centuries, \"á\" and \"ǫ́\" merged as ; later on at the beginning of the 14th century, delabialization took place: \"y\", \"øy\", \"au\" > /i, ɔi, ɛi/; \"í\" and \"ý\" merged in addition to \"i\" and \"y\", but in the case of \"í\" and \"ý\", it appears that labialisation took place instead as is documented by later development to.

Before the palatalisation \"é\" and \"ǽ\" merged as and approximately in the same period epenthetic \"u\" is inserted into word-final and clusters.

The shift of \"hv\" to, the deletion of in (remaining) word-initial –sonorant clusters (\"hr\", \"hl\", \"hn\" > \"r\", \"l\", \"n\"), and the dissolution of \"þ\" (\"þ\" > \"t\"; \"þ\" > \"h\" in demonstrative pronouns and adverbs) appeared before the end of the 13th century.

In his words, \"the cork was not attracted to the inside of the can as it would have been to the outside, and though it touched the bottom, yet when drawn out it was not found to be electrified (charged) by that touch, as it would have been by touching the outside. The fact is singular.\" Franklin had discovered the behavior of what we now refer to as a Faraday cage or shield (based on Faraday's later experiments which duplicated Franklin's cork and can).

This charges the outer face of the cage with a charge equal in sign and magnitude to the one placed inside the cage. Let's denote this charge quantity as Q. Since the internal charge and the inner face cancel each other out (i.e., the charge distribution on the inner surface produces a static electric field that's exactly the opposite of what's produced by the internal charge, hence the net charge, net dipole moment, etc., are all zero), the spread of charges on the outer face is not affected by the position of the internal charge inside the cage, but rather determined by the shape of outer face. So for all intents and purposes, the cage generates the same static electric field that it would generate if it were simply charged with Q. However, note that the same is not true for electromagnetic waves. If the cage is grounded, the excess charges will be neutralized as the ground connection creates an equipotential bonding between the outside of the cage and the environment, so there is no voltage between them and therefore also no field.

In this case the shielding also depends on the electrical conductivity, the magnetic properties of the conductive materials used in the cages, as well as their thicknesses. A good idea of the effectiveness of a Faraday shield can be obtained from considerations of skin depth. With skin depth, the current flowing is mostly in the surface, and decays exponentially with depth through the material.

As chief of the Praetorian Guard and father in law of the Emperor, Timesitheus quickly became the \"de facto\" ruler of the Roman Empire. In the 3rd century, the Roman frontiers weakened against the Germanic tribes across the Rhine and Danube, and the Sassanid Empire across the Euphrates increased its own attacks. When the Persians under Shapur I invaded Mesopotamia, the young emperor opened the doors of the Temple of Janus for the last time in Roman history, and sent a large army to the East. The Sassanids were driven back over the Euphrates and defeated in the Battle of Resaena (243). The campaign was a success and Gordian, who had joined the army, was planning an invasion of the enemy's territory, when his father-in-law died in unclear circumstances. Without Timesitheus, the campaign, and the Emperor's security, were at risk. Gaius Julius Priscus and, later on, his own brother Marcus Julius Philippus, also known as Philip the Arab, stepped in at this moment as the new Praetorian Prefects and the campaign proceeded. Around February 244, the Persians fought back fiercely to halt the Roman advance to Ctesiphon. The eventual fate of Gordian after the battle is unclear.

The Alemannic German language took hold only gradually, and was dominant by the 11th century. By 1288, the Habsburgs had claimed all the abbey's rights. Glarus joined the Old Swiss Confederacy in 1352 as one of the foundational eight cantons (\"Acht Orte\") of the period of 1353–1481. The first recorded Landsgemeinde of Glarus took place in 1387. Habsburg attempts to reconquer the valley were repelled in the Battle of Näfels of 1388. A banner depicting Saint Fridolin was used to rally the people of Glarus at that battle, and from that time Glarus has used the image of Saint Fridolin on its flags and in its coat of arms. The County of Werdenberg was annexed to Glarus in 1517. Between 1506 and 1516 the later reformer Huldrych Zwingli was priest in Glarus, but Glarus remained Catholic, and by 1564 all of Zwingli's followers were eliminated.

Glucagon also decreases fatty acid synthesis in adipose tissue and the liver, as well as promoting lipolysis in these tissues, which causes them to release fatty acids into circulation where they can be catabolised to generate energy in tissues such as skeletal muscle when required. Glucose is stored in the liver in the form of the polysaccharide glycogen, which is a glucan (a polymer made up of glucose molecules). Liver cells (hepatocytes) have glucagon receptors. When glucagon binds to the glucagon receptors, the liver cells convert the glycogen into individual glucose molecules and release them into the bloodstream, in a process known as glycogenolysis. As these stores become depleted, glucagon then encourages the liver and kidney to synthesize additional glucose by gluconeogenesis. Glucagon turns off glycolysis in the liver, causing glycolytic intermediates to be shuttled to gluconeogenesis. Glucagon also regulates the rate of glucose production through lipolysis. Glucagon induces lipolysis in humans under conditions of insulin suppression (such as diabetes mellitus type 1). Glucagon production appears to be dependent on the central nervous system through pathways yet to be defined.

The conformation change in the receptor activates G proteins, a heterotrimeric protein with α, β, and γ subunits. When the G protein interacts with the receptor, it undergoes a conformational change that results in the replacement of the GDP molecule that was bound to the α subunit with a GTP molecule. This substitution results in the releasing of the α subunit from the β and γ subunits. The alpha subunit specifically activates the next enzyme in the cascade, adenylate cyclase. Adenylate cyclase manufactures cyclic adenosine monophosphate (cyclic AMP or cAMP), which activates protein kinase A (cAMP-dependent protein kinase). This enzyme, in turn, activates phosphorylase kinase, which then phosphorylates glycogen phosphorylase b (PYG b), converting it into the active form called phosphorylase a (PYG a). Phosphorylase a is the enzyme responsible for the release of glucose 1-phosphate from glycogen polymers. An example of the pathway would be when glucagon binds to a transmembrane protein. The transmembrane proteins interacts with Gɑβγ. Gɑ separates from Gβγ and interacts with the transmembrane protein adenylyl cyclase. Adenylyl cyclase catalyzes the conversion of ATP to cAMP. cAMP binds to protein kinase A, and the complex phosphorylates phosphorylase kinase. Phosphorylated phosphorylase kinase phosphorylates phosphorylase. Phosphorylated phosphorylase clips glucose units from glycogen as glucose 1-phosphate. Additionally, the coordinated control of glycolysis and gluconeogenesis in the liver is adjusted by the phosphorylation state of the enzymes that catalyze the formation of a potent activator of glycolysis called fructose 2,6-bisphosphate. The enzyme protein kinase A (PKA) that was stimulated by the cascade initiated by glucagon will also phosphorylate a single serine residue of the bifunctional polypeptide chain containing both the enzymes fructose 2,6-bisphosphatase and phosphofructokinase-2. This covalent phosphorylation initiated by glucagon activates the former and inhibits the latter. This regulates the reaction catalyzing fructose 2,6-bisphosphate (a potent activator of phosphofructokinase-1, the enzyme that is the primary regulatory step of glycolysis) by slowing the rate of its formation, thereby inhibiting the flux of the glycolysis pathway and allowing gluconeogenesis to predominate.

In rodents, the alpha cells are located in the outer rim of the islet. Human islet structure is much less segregated, and alpha cells are distributed throughout the islet in close proximity to beta cells. Glucagon is also produced by alpha cells in the stomach.

The keel, or keelplank, was only slightly thicker than the adjacent garboards and had no rabbet. Both stem and stern posts were straight and rather long, and connected to the keelplank through intermediate pieces called hooks. The lower plank hoods terminated in rabbets in the hooks and posts, but upper hoods were nailed to the exterior faces of the posts. Caulking was generally tarred moss that was inserted into curved grooves, covered with wooden laths, and secured by metal staples called \"sintels\".

These early cogs were influenced by the Norse knarr, which was the main trade vessel in northern Europe at the time, and probably used a steering oar, as there is nothing to suggest a stern rudder in northern Europe until about 1240. Current archaeological evidence points to the Frisian coast or Western Jutland as the possible birthplace of this type of vessel. The transformation of the cog into a true seagoing trader came not only during the time of the intense trade between West and East, but also as a direct answer to the closure of the western entrance to the Limfjord. For centuries, Limfjord in northern Jutland offered fairly protected passage between the North Sea and the Baltic. Due to unusual geographical conditions and strong currents, the passage was constantly filling with sand and was completely blocked by the 12th century. This change produced new challenges. Bigger ships that could not be pulled across the sand bars had to sail around the Jutland peninsula and circumnavigate the dangerous Cape Skagen to get to the Baltic. This resulted in major modifications to old ship structures, which can be observed by analyzing evolution of the earliest cog finds of \"Kollerup\", \"Skagen\", and \"Kolding\". The need for spacious and relatively inexpensive ships led to the development of the first workhorse of the Hanseatic League, the cog. The new and improved cog was no longer a simple Frisian coaster but a sturdy seagoing trader, which could cross even the most dangerous passages. Fore and stern castles would be added for defense against pirates, or to enable use of these vessels as warships, such as used at the Battle of Sluys. The stern castle also afforded more cargo space below by keeping the crew and tiller up, out of the way. Eventually, around the 14th century, the cog reached its structural limits, resulting in the desperate need for a quick replacement. The replacement, the hulk, already existed but awaited reconditioning. Although there is no evidence that hulks descended from the cogs, it is clear that a lot of technological ideas were adapted from one to the other and vice versa. The transition from cogs to hulks was not linear.

These writers concern themselves with the size of the Hanging Gardens, their overall design and means of irrigation, and why they were built. Josephus (37–100 AD) quotes a description of the gardens by Berossus, a Babylonian priest of Marduk, whose writing circa 290 BC is the earliest known mention of the gardens. Berossus described the reign of Nebuchadnezzar II and is the only source to credit that king with the construction of the Hanging Gardens. Diodorus Siculus (active 60–30 BC) seems to have consulted the 4th century BC texts of both Cleitarchus (a historian of Alexander the Great) and Ctesias of Cnidus. Diodorus ascribes the construction to a Syrian king. He states that the garden was in the shape of a square, with each side approximately four plethra long. The garden was tiered, with the uppermost gallery being 50 cubits high. The walls, 22 feet thick, were made of brick. The bases of the tiered sections were sufficiently deep to provide root growth for the largest trees, and the gardens were irrigated from the nearby Euphrates. Quintus Curtius Rufus (fl. 1st century AD) probably drew on the same sources as Diodorus. He states that the gardens were located on top of a citadel, which was 20 stadia in circumference. He attributes the building of the gardens to a Syrian king, again for the reason that his queen missed her homeland. The account of Strabo (64 BC – 21 AD) possibly based his description on the lost account of Onesicritus from the 4th century BC. He states that the gardens were watered by means of an Archimedes' screw leading to the gardens from the Euphrates river. The last of the classical sources, thought to be independent of the others, is \"A Handbook to the Seven Wonders of the World\" by Philo of Byzantium (writing in the 4th to 5th century AD; not to be confused with Philo of Byzantium, who lived ca. 280 BC – ca. 220 BC).

Many records exist of Nebuchadnezzar's works, yet his long and complete inscriptions do not mention any garden. However, the gardens were said to still exist at the time that later writers described them, and some of these accounts are regarded as deriving from people who had visited Babylon. Herodotus, who describes Babylon in his \"Histories\", does not mention the Hanging Gardens, although it could be that the gardens were not yet well known to the Greeks at the time of his visit. To date, no archaeological evidence has been found at Babylon for the Hanging Gardens. It is possible that evidence exists beneath the Euphrates, which cannot be excavated safely at present. The river flowed east of its current position during the time of Nebuchadnezzar II, and little is known about the western portion of Babylon.

Stephanie Dalley posits that during the intervening centuries the two sites became confused, and the extensive gardens at Sennacherib's palace were attributed to Nebuchadnezzar II's Babylon. Archaeological excavations have found traces of a vast system of aqueducts attributed to Sennacherib by an inscription on its remains, which Dalley proposes were part of an series of canals, dams, and aqueducts used to carry water to Nineveh with water-raising screws used to raise it to the upper levels of the gardens. Dalley bases her arguments on recent developments in the analysis of contemporary Akkadian inscriptions. Her main points are: King Sennacherib's garden was well-known not just for its beauty – a year-round oasis of lush green in a dusty summer landscape – but also for the marvelous feats of water engineering that maintained the garden. There was a tradition of Assyrian royal garden building. King Ashurnasirpal II (883–859 BC) had created a canal, which cut through the mountains. Fruit tree orchards were planted. Also mentioned were pines, cypresses and junipers; almond trees, date trees, ebony, rosewood, olive, oak, tamarisk, walnut, terebinth, ash, fir, pomegranate, pear, quince, fig, and grapes. A sculptured wall panel of Assurbanipal shows the garden in its maturity. One original panel and the drawing of another are held by the British Museum, although neither is on public display. Several features mentioned by the classical authors are discernible on these contemporary images. The irrigation of such a garden demanded an upgraded water supply to the city of Nineveh. The canals stretched over 50 km into the mountains. Sennacherib was proud of the technologies he had employed and describes them in some detail on his inscriptions. At the headwater of Bavian (Khinnis) his inscription mentions automatic sluice gates. An enormous aqueduct crossing the valley at Jerwan was constructed of over 2 million dressed stones. It used stone arches and waterproof cement. On it is written: Sennacherib king of the world king of Assyria. Over a great distance I had a watercourse directed to the environs of Nineveh, joining together the waters... Over steep-sided valleys I spanned an aqueduct of white limestone blocks, I made those waters flow over it. Sennacherib claimed that he had built a \"Wonder for all Peoples,\" and said he was the first to deploy a new casting technique in place of the \"lost-wax\" process for his monumental (30 tonne) bronze castings. He was able to bring the water into his garden at a high level because it was sourced from further up in the mountains, and he then raised the water even higher by deploying his new water screws.

Kelvin calculated that absolute zero was equivalent to −273 °C on the air thermometers of the time. This absolute scale is known today as the Kelvin thermodynamic temperature scale. Kelvin's value of \"−273\" was the negative reciprocal of 0.00366—the accepted expansion coefficient of gas per degree Celsius relative to the ice point, giving a remarkable consistency to the currently accepted value. In 1954, Resolution 3 of the 10th General Conference on Weights and Measures (CGPM) gave the Kelvin scale its modern definition by designating the triple point of water as its second defining point and assigned its temperature to exactly 273.16 kelvins. In 1967/1968, Resolution 3 of the 13th CGPM renamed the unit increment of thermodynamic temperature \"kelvin\", symbol K, replacing \"degree Kelvin\", symbol °K. Furthermore, feeling it useful to more explicitly define the magnitude of the unit increment, the 13th CGPM also held in Resolution 4 that \"The kelvin, unit of thermodynamic temperature, is equal to the fraction of the thermodynamic temperature of the triple point of water.\" In 2005, the Comité International des Poids et Mesures (CIPM), a committee of the CGPM, affirmed that for the purposes of delineating the temperature of the triple point of water, the definition of the Kelvin thermodynamic temperature scale would refer to water having an isotopic composition specified as Vienna Standard Mean Ocean Water.

When reference is made to the \"Kelvin \"scale\"\", the word \"kelvin\"—which is normally a noun—functions adjectivally to modify the noun \"scale\" and is capitalized. As with most other SI unit symbols (angle symbols, e.g. 45° 3′ 4′′, are the exception) there is a space between the numeric value and the kelvin symbol (e.g. \"99.987 K\"). (The style guide for CERN, however, specifically says to always use \"kelvin\", even when plural.) Before the 13th CGPM in 1967–1968, the unit kelvin was called a \"degree\", the same as with the other temperature scales at the time. It was distinguished from the other scales with either the adjective suffix \"Kelvin\" (\"degree Kelvin\") or with \"absolute\" (\"degree absolute\") and its symbol was °K. The latter term (degree absolute), which was the unit's official name from 1948 until 1954, was ambiguous since it could also be interpreted as referring to the Rankine scale. Before the 13th CGPM, the plural form was \"degrees absolute\". The 13th CGPM changed the unit name to simply \"kelvin\" (symbol: K). The omission of \"degree\" indicates that it is not relative to an arbitrary reference point like the Celsius and Fahrenheit scales (although the Rankine scale continued to use \"degree Rankine\"), but rather an absolute unit of measure which can be manipulated algebraically (e.g. multiplied by two to indicate twice the amount of \"mean energy\" available among elementary degrees of freedom of the system).", "section_level": 1}, {"title": "2019 redefinition.", "content": "In 2005 the CIPM embarked on a programme to redefine the kelvin (along with the other SI units) using a more experimentally rigorous methodology.

The redefinition was further postponed in 2014, pending more accurate measurements of Boltzmann's constant in terms of the current definition, but was finally adopted at the 26th CGPM in late 2018, with a value of =. From a scientific point of view, the main advantage is that this will allow measurements at very low and very high temperatures to be made more accurately, as the techniques used depend on the Boltzmann constant. It also has the philosophical advantage of being independent of any particular substance. The challenge was to avoid degrading the accuracy of measurements close to the triple point. From a practical point of view, the redefinition will pass unnoticed; water will still freeze at 273.15 K (0 °C), and the triple point of water will continue to be a commonly used laboratory reference temperature. The difference is that, before the redefinition, the triple point of water was exact and the Boltzmann constant had a measured value of, with a relative standard uncertainty of.

The traditional view of banks as intermediaries between savers and borrowers is incorrect. Modern banking is about credit creation. Credit is made up of two parts, the credit (money) and its corresponding debt, which requires repayment with interest. The majority (97% as of December 2013) of the money in the UK economy is created as credit. When a bank issues credit (i.e. makes a loan), it writes a negative entry in to the liabilities column of its balance sheet, and an equivalent positive figure on the assets column; the asset being the loan repayment income stream (plus interest) from a credit-worthy individual. When the debt is fully repaid, the credit and debt are canceled, and the money disappears from the economy. Meanwhile, the debtor receives a positive cash balance (which is used to purchase something like a house), but also an equivalent negative liability to be repaid to the bank over the duration. Most of the credit created goes into the purchase of land and property, creating inflation in those markets, which is a major driver of the economic cycle. When a bank creates credit, it effectively owes the money to itself. If a bank issues too much bad credit (those debtors who are unable to pay it back), the bank will become insolvent; having more liabilities than assets. That the bank never had the money to lend in the first place is immaterial - the banking license affords banks to create credit - what matters is that a bank's total assets are greater than its total liabilities and that it is holding sufficient liquid assets - such as cash - to meet its obligations to its debtors. If it fails to do this it risks bankruptcy. There are two main forms of private credit created by banks; unsecured (non-collateralized) credit such as consumer credit cards and small unsecured loans, and secured (collateralized) credit, typically secured against the item being purchased with the money (house, boat, car, etc.). To reduce their exposure to the risk of not getting their money back (credit default), banks will tend to issue large credit sums to those deemed credit-worthy, and also to require collateral; something of equivalent value to the loan, which will be passed to the bank if the debtor fails to meet the repayment terms of the loan. In this instance, the bank uses sale of the collateral to reduce its liabilities. Examples of secured credit include consumer mortgages used to buy houses, boats, etc., and PCP (personal contract plan) credit agreements for automobile purchases. Movements of financial capital are normally dependent on either credit or equity transfers. The global credit market is three times the size of global equity. Credit is in turn dependent on the reputation or creditworthiness of the entity which takes responsibility for the funds. Credit is also traded in financial markets. The purest form is the credit default swap market, which is essentially a traded market in credit insurance. A credit default swap represents the price at which two parties exchange this riskthe protection \"seller\" takes the risk of default of the credit in return for a payment, commonly denoted in basis points (one basis point is 1/100 of a percent) of the notional amount to be referenced, while the protection \"buyer\" pays this premium and in the case of default of the underlying (a loan, bond or other receivable), delivers this receivable to the protection seller and receives from the seller the paramount (that is, is made whole).", "section_level": 1}, {"title": "Types.", "content": "There are many types of credit, including but not limited to bank credit, commerce, consumer credit, investment credit, international credit, public credit and real estate.", "section_level": 1}, {"title": "Trade credit.", "content": "In commercial trade, the term \"trade credit\" refers to the approval of delayed payment for purchased goods.

Common forms of consumer credit include credit cards, store cards, motor vehicle finance, personal loans (installment loans), consumer lines of credit, payday loans, retail loans (retail installment loans) and mortgages. This is a broad definition of consumer credit and corresponds with the Bank of England's definition of \"Lending to individuals\". Given the size and nature of the mortgage market, many observers classify mortgage lending as a separate category of personal borrowing, and consequently, residential mortgages are excluded from some definitions of consumer credit, such as the one adopted by the U.S. Federal Reserve. The cost of credit is the additional amount, over and above the amount borrowed, that the borrower has to pay. It includes interest, arrangement fees and any other charges. Some costs are mandatory, required by the lender as an integral part of the credit agreement. Other costs, such as those for credit insurance, may be optional; the borrower chooses whether or not they are included as part of the agreement. Interest and other charges are presented in a variety of different ways, but under many legislative regimes lenders are required to quote all mandatory charges in the form of an annual percentage rate (APR). The goal of the APR calculation is to promote \"truth in lending\", to give potential borrowers a clear measure of the true cost of borrowing and to allow a comparison to be made between competing products. The APR is derived from the pattern of advances and repayments made during the agreement. Optional charges are usually not included in the APR calculation. Interest rates on loans to consumers, whether mortgages or credit cards are most commonly determined with reference to a credit score.

As such, its value can be estimated at a point in time. By contrast, investment, as production to be added to the capital stock, is described as taking place over time (\"per year\"), thus a flow. Marxian economics distinguishes between different forms of capital: Earlier illustrations often described capital as physical items, such as tools, buildings, and vehicles that are used in the production process. Since at least the 1960s economists have increasingly focused on broader forms of capital. For example, investment in skills and education can be viewed as building up human capital or knowledge capital, and investments in intellectual property can be viewed as building up intellectual capital. These terms lead to certain questions and controversies discussed in those articles.", "section_level": 1}, {"title": "Modern types of capital.", "content": "Detailed classifications of capital that have been used in various theoretical or applied uses generally respect the following division: Separate literatures have developed to describe both natural capital and social capital. Such terms reflect a wide consensus that nature and society both function in such a similar manner as traditional industrial infrastructural capital, that it is entirely appropriate to refer to them as different types of capital in themselves. In particular, they can be used in the production of other goods, are not used up immediately in the process of production, and can be enhanced (if not created) by human effort. There is also a literature of intellectual capital and intellectual property law. However, this increasingly distinguishes means of capital investment, and collection of potential rewards for patent, copyright (creative or individual capital), and trademark (social trust or social capital) instruments.", "section_level": 1}, {"title": "Interpretations.", "content": "Within classical economics, Adam Smith (\"Wealth of Nations\", Book II, Chapter 1) distinguished fixed capital from circulating capital. The former designated physical assets not consumed in the production of a product (e.g. machines and storage facilities), while the latter referred to physical assets consumed in the process of production (e.g. raw materials and intermediate products). For an enterprise, both were types of capital. Economist Henry George argued that financial instruments like stocks, bonds, mortgages, promissory notes, or other certificates for transferring wealth is not really capital, because \"Their economic value merely represents the power of one class to appropriate the earnings of another\" and \"their increase or decrease does not affect the sum of wealth in the community\". Some thinkers, such as Werner Sombart and Max Weber, locate the concept of capital as originating in double-entry bookkeeping, which is thus a foundational innovation in capitalism, Sombart writing in \"Medieval and Modern Commercial Enterprise\" that: Karl Marx adds a distinction that is often confused with David Ricardo's. In Marxian theory, variable capital refers to a capitalist's investment in labor-power, seen as the only source of surplus-value. It is called \"variable\" since the amount of value it can produce varies from the amount it consumes, \"i.e.\", it creates new value. On the other hand, constant capital refers to investment in non-human factors of production, such as plant and machinery, which Marx takes to contribute only its own replacement value to the commodities it is used to produce. Investment or capital accumulation, in classical economic theory, is the production of increased capital. Investment requires that some goods be produced that are not immediately consumed, but instead used to produce other goods as capital goods. Investment is closely related to saving, though it is not the same. As Keynes pointed out, saving involves not spending all of one's income on current goods or services, while investment refers to spending on a specific type of goods, \"i.e.\", capital goods. Austrian School economist Eugen Boehm von Bawerk maintained that capital intensity was measured by the roundaboutness of production processes. Since capital is defined by him as being goods of higher-order, or goods used to produce consumer goods, and derived their value from them, being future goods. Human development theory describes human capital as being composed of distinct social, imitative and creative elements: This theory is the basis of triple bottom line accounting and is further developed in ecological economics, welfare economics and the various theories of green economics. All of which use a particularly abstract notion of capital in which the requirement of capital being produced like durable goods is effectively removed. The Cambridge capital controversy was a dispute between economists at Cambridge, Massachusetts based MIT and University of Cambridge in the UK about the measurement of capital. The Cambridge, UK economists, including Joan Robinson and Piero Sraffa claimed that there is no basis for aggregating the heterogeneous objects that constitute 'capital goods.' Political economists Jonathan Nitzan and Shimshon Bichler have suggested that capital is not a productive entity, but solely financial and that capital values measure the relative power of owners over the broad social processes that bear on profits.", "section_level": 1}], "src_summary": "In economics, capital consists of assets that can enhance one's power to perform economically useful work. For example, a stone or an arrow is capital for a hunter-gatherer who can use it as a hunting instrument; similarly, roads are capital for inhabitants of a city. Capital is distinct from land and other non-renewable resources in that it can be increased by human labor, and does not include certain durable goods like homes and personal automobiles that are not used in the production of saleable goods and services. Adam Smith defined capital as \"that part of man's stock which he expects to afford him revenue\". In economic models, capital is an input in the production function. The total physical capital at any given moment in time is referred to as the capital stock (not to be confused with the capital stock of a business entity). Capital goods, real capital, or capital assets are already-produced, durable goods or any non-financial asset that is used in production of goods or services. In Marxian economics, capital is money used to buy something only in order to sell it again to realize a profit. For Marx, capital only exists within the process of the economic circuit (represented by M-C-M')—it is wealth that grows out of the process of circulation itself, and for Marx it formed the basis of the economic system of capitalism. In more contemporary schools of economics, this form of capital is generally referred to as \"financial capital\" and is distinguished from \"capital goods\".", "tgt_summary": null, "id": 4970951} {"src_title": "Polygonaceae", "tgt_title": null, "src_document": [{"title": "Taxonomy.", "content": "Polygonaceae are very well-defined and have long been universally recognized.

Advancing technology makes more complex and powerful chips feasible to manufacture. A minimal hypothetical microprocessor might include only an arithmetic logic unit (ALU), and a control logic section. The ALU performs addition, subtraction, and operations such as AND or OR. Each operation of the ALU sets one or more flags in a status register, which indicate the results of the last operation (zero value, negative number, overflow, or others). The control logic retrieves instruction codes from memory and initiates the sequence of operations required for the ALU to carry out the instruction. A single operation code might affect many individual data paths, registers, and other elements of the processor. As integrated circuit technology advanced, it was feasible to manufacture more and more complex processors on a single chip. The size of data objects became larger; allowing more transistors on a chip allowed word sizes to increase from 4- and 8-bit words up to today's 64-bit words. Additional features were added to the processor architecture; more on-chip registers sped up programs, and complex instructions could be used to make more compact programs. Floating-point arithmetic, for example, was often not available on 8-bit microprocessors, but had to be carried out in software. Integration of the floating point unit first as a separate integrated circuit and then as part of the same microprocessor chip sped up floating point calculations. Occasionally, physical limitations of integrated circuits made such practices as a bit slice approach necessary. Instead of processing all of a long word on one integrated circuit, multiple circuits in parallel processed subsets of each data word. While this required extra logic to handle, for example, carry and overflow within each slice, the result was a system that could handle, for example, 32-bit words using integrated circuits with a capacity for only four bits each. The ability to put large numbers of transistors on one chip makes it feasible to integrate memory on the same die as the processor. This CPU cache has the advantage of faster access than off-chip memory and increases the processing speed of the system for many applications.

General-purpose microprocessors in personal computers are used for computation, text editing, multimedia display, and communication over the Internet. Many more microprocessors are part of embedded systems, providing digital control over myriad objects from appliances to automobiles to cellular phones and industrial process control. Microprocessors perform binary operations based on Boolean Logic, named after George Boole. The ability to operate computer systems using Boolean Logic was first proven in a 1938 Thesis by Masters Student Claude Shannon, who later went on to become a Professor. Shannon is considered \"The Father of Information Theory\". The microprocessor has origins in the development of the MOSFET (metal-oxide-semiconductor field-effect transistor, or MOS transistor), which was first demonstrated by Mohamed M. Atalla and Dawon Kahng of Bell Labs in 1960. Following the development of MOS integrated circuit chips in the early 1960s, MOS chips reached higher transistor density and lower manufacturing costs than bipolar integrated circuits by 1964. MOS chips further increased in complexity at a rate predicted by Moore's law, leading to large-scale integration (LSI) with hundreds of transistors on a single MOS chip by the late 1960s. The application of MOS LSI chips to computing was the basis for the first microprocessors, as engineers began recognizing that a complete computer processor could be contained on several MOS LSI chips. Designers in the late 1960s were striving to integrate the central processing unit (CPU) functions of a computer onto a handful of MOS LSI chips, called microprocessor unit (MPU) chipsets. The first true microprocessor was the Intel 4004, released as a single MOS LSI chip in 1971. The single-chip microprocessor was made possible with the development of MOS silicon-gate technology (SGT). The earliest MOS transistors had aluminium metal gates, which Italian engineer Federico Faggin replaced with silicon self-aligned gates to develop the first silicon-gate MOS chip at Fairchild Semiconductor in 1968. Faggin later joined Intel and used his silicon-gate MOS technology to develop the 4004, along with Marcian Hoff, Stanley Mazor and Masatoshi Shima in 1971. The 4004 was designed for Busicom, which had earlier proposed a multi-chip design in 1969, before Faggin's team at Intel changed it into a new single-chip design. Intel introduced the first commercial microprocessor, the 4-bit Intel 4004, in 1971. It was soon followed by the 8-bit microprocessor Intel 8008 in 1972. Other embedded uses of 4-bit and 8-bit microprocessors, such as terminals, printers, various kinds of automation etc., followed soon after. Affordable 8-bit microprocessors with 16-bit addressing also led to the first general-purpose microcomputers from the mid-1970s on. The first use of the term \"microprocessor\" is attributed to Viatron Computer Systems describing the custom integrated circuit used in their System 21 small computer system announced in 1968. Since the early 1970s, the increase in capacity of microprocessors has followed Moore's law; this originally suggested that the number of components that can be fitted onto a chip doubles every year.

This anterior body region is called the capitulum or gnathosoma, and according to some works, is also found in the Ricinulei. The remainder of the body is called the idiosoma and is unique to mites. Most adult mites have four pairs of legs, like other arachnids, but some have fewer. For example, gall mites like \"Phyllocoptes variabilis\" (family Eriophyidae) have a worm-like body with only two pairs of legs; some parasitic mites have only one or three pairs of legs in the adult stage. Larval and prelarval stages have a maximum of three pairs of legs; adult mites with only three pairs of legs may be called 'larviform'. Also, members of the Nematalycidae within the Endeostigmata, which live between sand grains, have often worm-like and elongated bodies with reduced legs.

Usually, a maximum of three nymphal stages are present and they are referred to in sequence as the protonymph, deutonymph, and tritonymph; however, some soft ticks have supernumerary nymphal stages.

They may feed on uropygial oil, skin flakes, fungus, bacteria, and feathers, depending on the taxon to which they belong.

A well-known effect of mites on humans is their role as allergens and the stimulation of asthma in people affected by respiratory disease. The use of predatory mites (for example, Phytoseiidae) in pest control and herbivorous mites that infest weeds are also of importance. An unquantified, but major positive contribution of the Acari is their normal functioning in ecosystems, especially their roles in the decomposer subsystem.

In most modern treatments, the Acari are considered a subclass of the Arachnida and are composed of two or three superorders or orders: Acariformes (or Actinotrichida), Parasitiformes (or Anactinotrichida), and Opilioacariformes; the latter is often considered a subgroup within the Parasitiformes. The monophyly of the Acari is open to debate, and the relationships of the acarines to other arachnids is not at all clear.

Instructions are patterns of bits, digits or characters that by physical design correspond to different commands to the machine. Thus, the instruction set is specific to a class of processors using (mostly) the same architecture. Successor or derivative processor designs often include all the instructions of a predecessor and may add additional instructions. Occasionally, a successor design will discontinue or alter the meaning of some instruction code (typically because it is needed for new purposes), affecting code compatibility to some extent; even nearly completely compatible processors may show slightly different behavior for some instructions, but this is rarely a problem. Systems may also differ in other details, such as memory arrangement, operating systems, or peripheral devices. Because a program normally relies on such factors, different systems will typically not run the same machine code, even when the same type of processor is used. A processor's instruction set may have all instructions of the same length, or it may have variable-length instructions. How the patterns are organized varies strongly with the particular architecture and often also with the type of instruction. Most instructions have one or more opcode fields which specifies the basic instruction type (such as arithmetic, logical, jump, etc.) and the actual operation (such as add or compare) and other fields that may give the type of the operand(s), the addressing mode(s), the addressing offset(s) or index, or the actual value itself (such constant operands contained in an instruction are called \"immediates\"). Not all machines or individual instructions have explicit operands. An accumulator machine has a combined left operand and result in an implicit accumulator for most arithmetic instructions. Other architectures (such as 8086 and the x86-family) have accumulator versions of common instructions, with the accumulator regarded as one of the general registers by longer instructions. A stack machine has most or all of its operands on an implicit stack. Special purpose instructions also often lack explicit operands (CPUID in the x86 architecture writes values into four implicit destination registers, for instance). This distinction between explicit and implicit operands is important in code generators, especially in the register allocation and live range tracking parts. A good code optimizer can track implicit as well as explicit operands which may allow more frequent constant propagation, constant folding of registers (a register assigned the result of a constant expression freed up by replacing it by that constant) and other code enhancements.", "section_level": 1}, {"title": "Programs.", "content": "A computer program is a list of instructions that can be executed by a central processing unit (CPU).

This put American multinational Procter & Gamble out of the bidding and preserved Beiersdorf as a publicly traded, stand-alone company in Hamburg. As host of Hamburg's annual St. Matthew's Day banquet for the city's civic and business leaders, von Beust invited several high-ranking guests of honour to the city, including Queen Silvia of Sweden (2003), King Abdullah II of Jordan (2005), Crown Prince Frederik of Denmark (2006), President Jakaya Kikwete of Tanzania (2008). On 19 August 2003, von Beust dismissed his vice-mayor, Ronald Schill, causing a scandal. Von Beust had earlier dismissed Walter Wellinghausen, senator of the interior and Schill's most important official, without consulting Schill beforehand. This was due to public allegations of misconduct on Wellinghausen's part. In a private conversation, Schill then demanded that Beust take back the dismissal, allegedly using personal threats. Beust then decided to dismiss Schill as well. In the (preassigned) press conference Schill held minutes after he had heard of his own dismissal, he spoke vaguely of \"homosexual relationships\", a \"flat in an infamous hustler district\" and \"certain things happened that let one infer the occurrence of love acts\" between von Beust and Roger Kusch, who von Beust had appointed minister (in German city-states \"senator\") of justice. Beust in turn stated that Schill threatened to make his alleged liaison with Kusch public under the premise that Beust intermingled public and private affairs. He said he had no sexual relationship with Kusch, that they merely knew each other for 25 years and were good friends, and that Beust was Kusch's landlord. \"This is all – absolutely all\", according to Beust. His unprepared statement to the press quickly earned Schill a homophobic reputation. A popular radio-station broadcast a song calling him \"Mega-Proll\" (mega redneck) and gay and lesbian associations protested vocally. Schill however later affirmed von Beust's version of the story, except for the accusations of blackmail, saying that he warned von Beust to stay clear of nepotism, and that this had nothing to do with Beust's sexual orientation. He stated \"I have nothing against homosexuals\". In a later interview, von Beust's father confirmed that his son is indeed homosexual. Beust himself considers his sexual orientation a private matter; when asked directly he usually ironically refers the interviewer to his father.

The CDU gained 47.2 percent of the vote, a full 21-point increase from the previous election in September 2001. This was the first time since 1993 the city-state has had only a single ruling party. Under von Beust's leadership, the Hamburg state government made the decision to commence construction of the Elbphilharmonie, a concert hall in the quarter.

Third term In the Hamburg elections of 24 February 2008, the CDU gained 42.6 percent of the vote. Thus, the CDU continued to be the strongest party in Hamburg. However, since the CDU lost its absolute majority, it formed a coalition government with the Greens. At the time, the two party's cooperation was widely seen as a test for a possible coalition at the national level. In February 2009, von Beust and Minister President Peter Harry Carstensen of Schleswig-Holstein agreed on a €13 billion bailout of state-owned shipping financier HSH Nordbank. The two states were forced to intervene after the SoFFin fund, which had been set up by the federal government in 2008 to stabilize the financial markets, said it could not help out HSH Nordbank until it got rid of all its bad debts. Ahead of the 2009 national elections, von Beust was tipped as potential Federal Minister for Economic Cooperation and Development in the cabinet of Chancellor Angela Merkel; in the negotiations on a coalition agreement with the FDP, however, the position went to Dirk Niebel.

At room temperature plutonium is in its α (\"alpha\") form. This, the most common structural form of the element (allotrope), is about as hard and brittle as gray cast iron unless it is alloyed with other metals to make it soft and ductile. Unlike most metals, it is not a good conductor of heat or electricity. It has a low melting point (640 °C) and an unusually high boiling point (3,228 °C). Alpha decay, the release of a high-energy helium nucleus, is the most common form of radioactive decay for plutonium. A 5 kg mass of Pu contains about atoms. With a half-life of 24,100 years, about of its atoms decay each second by emitting a 5.157 MeV alpha particle. This amounts to 9.68 watts of power. Heat produced by the deceleration of these alpha particles makes it warm to the touch. Resistivity is a measure of how strongly a material opposes the flow of electric current. The resistivity of plutonium at room temperature is very high for a metal, and it gets even higher with lower temperatures, which is unusual for metals. This trend continues down to 100 K, below which resistivity rapidly decreases for fresh samples. Resistivity then begins to increase with time at around 20 K due to radiation damage, with the rate dictated by the isotopic composition of the sample. Because of self-irradiation, a sample of plutonium fatigues throughout its crystal structure, meaning the ordered arrangement of its atoms becomes disrupted by radiation with time. Self-irradiation can also lead to annealing which counteracts some of the fatigue effects as temperature increases above 100 K. Unlike most materials, plutonium increases in density when it melts, by 2.5%, but the liquid metal exhibits a linear decrease in density with temperature. Near the melting point, the liquid plutonium has very high viscosity and surface tension compared to other metals.", "section_level": 2}, {"title": "Allotropes.", "content": "Plutonium normally has six allotropes and forms a seventh (zeta, ζ) at high temperature within a limited pressure range. These allotropes, which are different structural modifications or forms of an element, have very similar internal energies but significantly varying densities and crystal structures. This makes plutonium very sensitive to changes in temperature, pressure, or chemistry, and allows for dramatic volume changes following phase transitions from one allotropic form to another. The densities of the different allotropes vary from 16.00 g/cm to 19.86 g/cm. The presence of these many allotropes makes machining plutonium very difficult, as it changes state very readily. For example, the α form exists at room temperature in unalloyed plutonium. It has machining characteristics similar to cast iron but changes to the plastic and malleable β (\"beta\") form at slightly higher temperatures. The reasons for the complicated phase diagram are not entirely understood. The α form has a low-symmetry monoclinic structure, hence its brittleness, strength, compressibility, and poor thermal conductivity. Plutonium in the δ (\"delta\") form normally exists in the 310 °C to 452 °C range but is stable at room temperature when alloyed with a small percentage of gallium, aluminium, or cerium, enhancing workability and allowing it to be welded. The δ form has more typical metallic character, and is roughly as strong and malleable as aluminium. In fission weapons, the explosive shock waves used to compress a plutonium core will also cause a transition from the usual δ phase plutonium to the denser α form, significantly helping to achieve supercriticality. The ε phase, the highest temperature solid allotrope, exhibits anomalously high atomic self-diffusion compared to other elements.", "section_level": 2}, {"title": "Nuclear fission.", "content": "Plutonium is a radioactive actinide metal whose isotope, plutonium-239, is one of the three primary fissile isotopes (uranium-233 and uranium-235 are the other two); plutonium-241 is also highly fissile. To be considered fissile, an isotope's atomic nucleus must be able to break apart or fission when struck by a slow moving neutron and to release enough additional neutrons to sustain the nuclear chain reaction by splitting further nuclei. Pure plutonium-239 may have a multiplication factor (k) larger than one, which means that if the metal is present in sufficient quantity and with an appropriate geometry (e.g., a sphere of sufficient size), it can form a critical mass. During fission, a fraction of the nuclear binding energy, which holds a nucleus together, is released as a large amount of electromagnetic and kinetic energy (much of the latter being quickly converted to thermal energy). Fission of a kilogram of plutonium-239 can produce an explosion equivalent to. It is this energy that makes plutonium-239 useful in nuclear weapons and reactors. The presence of the isotope plutonium-240 in a sample limits its nuclear bomb potential, as plutonium-240 has a relatively high spontaneous fission rate (~440 fissions per second per gram—over 1,000 neutrons per second per gram), raising the background neutron levels and thus increasing the risk of predetonation. Plutonium is identified as either weapons-grade, fuel-grade, or reactor-grade based on the percentage of plutonium-240 that it contains. Weapons-grade plutonium contains less than 7% plutonium-240. Fuel-grade plutonium contains from 7% to less than 19%, and power reactor-grade contains 19% or more plutonium-240. Supergrade plutonium, with less than 4% of plutonium-240, is used in U.S. Navy weapons stored in proximity to ship and submarine crews, due to its lower radioactivity.

All of the remaining radioactive isotopes have half-lives that are less than 7,000 years. This element also has eight metastable states, though all have half-lives less than one second. The known isotopes of plutonium range in mass number from 228 to 247. The primary decay modes of isotopes with mass numbers lower than the most stable isotope, plutonium-244, are spontaneous fission and alpha emission, mostly forming uranium (92 protons) and neptunium (93 protons) isotopes as decay products (neglecting the wide range of daughter nuclei created by fission processes). The primary decay mode for isotopes with mass numbers higher than plutonium-244 is beta emission, mostly forming americium (95 protons) isotopes as decay products. Plutonium-241 is the parent isotope of the neptunium decay series, decaying to americium-241 via beta emission. Plutonium-238 and 239 are the most widely synthesized isotopes. Plutonium-239 is synthesized via the following reaction using uranium (U) and neutrons (n) via beta decay (β) with neptunium (Np) as an intermediate: Neutrons from the fission of uranium-235 are captured by uranium-238 nuclei to form uranium-239; a beta decay converts a neutron into a proton to form neptunium-239 (half-life 2.36 days) and another beta decay forms plutonium-239.

Skeptical investigator Joe Nickell says that claimed poltergeist incidents typically originate from \"an individual who is motivated to cause mischief\". According to Nickell: \"In the typical poltergeist outbreak, small objects are hurled through the air by unseen forces, furniture is overturned, or other disturbances occur—usually just what could be accomplished by a juvenile trickster determined to plague credulous adults.\" Nickell writes that reports are often exaggerated by credulous witnesses. \"Time and again in other “poltergeist” outbreaks, witnesses have reported an object leaping from its resting place supposedly on its own, when it is likely that the perpetrator had secretly obtained the object sometime earlier and waited for an opportunity to fling it, even from outside the room—thus supposedly proving he or she was innocent.\" According to research in anomalistic psychology, claims of poltergeist activity can be explained by psychological factors such as illusion, memory lapses, and wishful thinking. A study (Lange and Houran, 1998) wrote that poltergeist experiences are delusions \"resulting from the affective and cognitive dynamics of percipients' interpretation of ambiguous stimuli\". Psychologist Donovan Rawcliffe has written that almost all poltergeist cases that have been investigated turned out to be based on trickery, whilst the rest are attributable to psychological factors such as hallucinations. Attempts have also been made to scientifically explain poltergeist disturbances that have not been traced to fraud or psychological factors. Skeptic and magician Milbourne Christopher found that some cases of poltergeist activity can be attributed to unusual air currents, such as a 1957 case on Cape Cod where downdrafts from an uncovered chimney became strong enough to blow a mirror off of a wall, overturn chairs and knock things off shelves.", "section_level": 2}, {"title": "Unverified natural phenomena.", "content": "In the 1950s, Guy William Lambert proposed that reported poltergeist phenomena could be explained by the movement of underground water causing stress on houses.

Probus became amongst the highest placed lieutenants of Aurelian, reconquering Egypt from Zenobia in 273 A.D.

In contrast to Florianus, who ignored the wishes of the senate, Probus referred his claim to Rome in a respectful dispatch. The senate enthusiastically ratified his pretensions. Probus next travelled west, defeating the Goths along the lower Danube in 277, and acquiring the title of \"Gothicus\". However, the Goths came to respect his ability and implored a treaty with the empire. In 278, Probus campaigned successfully in Gaul against the Alamanni and Longiones; both tribes had advanced through the Neckar valley and across the Rhine into Roman territory. Meanwhile, his generals defeated the Franks and these operations were directed to clearing Gaul of Germanic invaders (Franks and Burgundians), allowing Probus to adopt the titles of \"Gothicus Maximus\" and \"Germanicus Maximus\". Reportedly, 400,000 barbarians were killed during Probus' campaign, and the entire nation of the Lugii were extirpated. After the defeat of the Germanic invaders in Gaul, Probus crossed the Rhine to campaign successfully against the Barbarians in their homeland, forcing them to pay homage. In the aftermath of the campaign, Probus repaired the ancient fortifications erected by Hadrian in the vulnerable space between the Rhine and Danube, in the territory of Swabia. More significantly, Probus, by forcing from the vanquished tribes a tribute of manpower, established the precedent of settling barbarians within the empire as auxiliaries on a large scale. The provinces were depopulated by war, disease and the chaotic administration, heavy taxation, and extensive army recruitment, during the crisis of the Third century, and the barbarian colonies, at least in the short term, helped to restore frontier defense and the practice of agriculture. The army discipline which Aurelian had repaired was cultivated and extended under Probus, who was however more shy in the practice of cruelty. In 279–280, Probus was, according to Zosimus, in Raetia, Illyricum and Lycia, where he fought the Vandals. In the same years, Probus' generals defeated the Blemmyes in Egypt. Either then, or during his previous command in Egypt, he ordered the reconstruction of bridges and canals along the Nile, where the production of grain for the Empire was centered. In 280–281, Probus put down three usurpers, Julius Saturninus, Proculus and Bonosus. The extent of these revolts is not clear, but there are clues that they were not just local problems (an inscription with the name of Probus erased has been found as far as Spain). Following this, Probus then put down a revolt by an unnamed rebel in Britain with the assistance of a certain Victorinus, who was later made consul in 282.

This dream was interpreted by the seer Aesacus as a foretelling of the downfall of Troy, and he declared that the child would be the ruin of his homeland. On the day of Paris's birth, it was further announced by Aesacus that the child born of a royal Trojan that day would have to be killed to spare the kingdom, being the child that would bring about the prophecy. Though Paris was indeed born before nightfall, he was spared by Priam. Hecuba was also unable to kill the child, despite the urging of the priestess of Apollo, one Herophile. Instead, Paris's father prevailed upon his chief herdsman, Agelaus, to remove the child and kill him. The herdsman, unable to use a weapon against the infant, left him exposed on Mount Ida, hoping he would perish there (cf. Oedipus). He was, however, suckled by a she-bear. Returning after nine days, Agelaus was astonished to find the child still alive and brought him home in a backpack (Greek \"pḗra\", hence by folk etymology Paris’s name) to rear as his own. He returned to Priam bearing a dog's tongue as evidence of the deed's completion. Paris's noble birth was betrayed by his outstanding beauty and intelligence. While still a child, he routed a gang of cattle-thieves and restored the animals they had stolen to the herd, thereby earning the surname Alexander (\"protector of men\"). It was at this time that Oenone became Paris's first lover. She was a nymph from Mount Ida in Phrygia. Her father was Cebren, a river-god or, according to other sources, she was the daughter of Oeneus. She was skilled in the arts of prophecy and medicine, which she had been taught by Rhea and Apollo, respectively. When Paris later left her for Helen, she told him that if he ever was wounded, he should come to her, for she could heal any injury, even the most serious wounds. Paris's chief distraction at this time was to pit Agelaus's bulls against one another. One bull began to win these bouts consistently. Paris began to set it against rival herdsmen's own prize bulls and it defeated them all. Finally, Paris offered a golden crown to any bull that could defeat his champion.

The goddesses thought to be the most beautiful were Hera, Athena, and Aphrodite, and each one claimed the apple. They started a quarrel so they asked Zeus to choose one of them. Knowing that choosing any of them would bring him the hatred of the other two, Zeus did not want to take part in the decision. He thus appointed Paris to select the most beautiful. Escorted by Hermes, the three goddesses bathed in the spring of Mount Ida and approached Paris as he herded his cattle. Having been given permission by Zeus to set any conditions he saw fit, Paris required that the goddesses undress before him (alternatively, the goddesses themselves chose to disrobe to show all their beauty). Still, Paris could not decide, as all three were ideally beautiful, so the goddesses attempted to bribe him to choose among them. Hera offered ownership of all of Europe and Asia. Athena offered skill in battle, wisdom and the abilities of the greatest warriors. Aphrodite offered the love of the most beautiful woman on Earth: Helen of Sparta. Paris chose Aphrodite and therefore Helen. Helen was already married to King Menelaus of Sparta (a fact Aphrodite neglected to mention), so Paris had to raid Menelaus's house to steal Helen from him - according to some accounts, she fell in love with Paris and left willingly. The Greeks' expedition to retrieve Helen from Paris in Troy is the mythological basis of the Trojan War. This triggered the war because Helen was famous for her beauty throughout Achaea (ancient Greece), and had many suitors of extraordinary ability. Therefore, following Odysseus's advice, her father Tyndareus made all suitors promise to defend Helen's marriage to the man he chose for her. When Paris took her to Troy, Menelaus invoked this oath.

Although no original works exist that can be attributed to him with certainty, numerous Roman copies of varying degrees of fidelity are known to exist. This is not uncommon. Almost all classical Greek paintings and sculptures have been destroyed, and only Roman copies or notes of them exist, like the passages of Plato that ascribe Phidias' works to him. The ancient Romans frequently copied and further developed Greek art. The earliest of Phidias' works were dedications in memory of Marathon, celebrating the Greek victory. His first commission was a group of national heroes with Miltiades as a central figure. At Delphi he created a great group in bronze including the figures of Greek gods Apollo and Athena, several Attic heroes, and General Miltiades the Younger. On the Acropolis of Athens, Phidias constructed a colossal bronze statue of Athena, the \"Athena Promachos\", which was visible far out at sea. Athena was the goddess of wisdom and warriors and the protector of Athens. At Pellene in Achaea, and at Plataea, Phidias made two other statues of Athena, as well as a statue of the goddess Aphrodite in ivory and gold for the people of Elis. In antiquity, Phidias was celebrated for his statues in bronze and his chryselephantine works (statues made of gold and ivory). In the \"Hippias Major\", Plato claims that Phidias seldom, if ever, executed works in marble, though many of the sculptures of his time were executed in marble. Plutarch writes that he superintended the great works ordered by Greek statesman Pericles on the Acropolis. Ancient critics take a very high view of the merits of Phidias. What they especially praise is the ethos or permanent moral level of his works as compared with those of the later so called \"pathetic\" school. Both Pausanias and Plutarch mention works of his depicting the warlike Athena Areia. Demetrius calls his statues sublime, and at the same time precise. In 447 BCE, Pericles commissioned several sculptures for Athens from Phidias to celebrate the Greek victory against the Persians at the Battle of Marathon during the Greco-Persian Wars (490 BCE). Pericles used some of the money from the maritime League of Delos, to rebuild and decorate Athens to celebrate this victory. Inscriptions prove that the marble blocks intended for the pedimental statues of the Parthenon were not brought to Athens until 434BCE. It is therefore possible that most of sculptural decoration of the Parthenon was the work of Phidias' workshop including pupils of Phidias, such as Alcamenes and Agoracritus. According to geographer Pausanias (1.28.2), the original bronze \"Athena Lemnia\" was created by Phidias ( 450–440BCE) for Athenians living on Lemnos. He described it as \"the best of all Pheidias's works to see\". Adolf Furtwängler suggested that he found a copy of the \"Athena Lemnia\" in a statue of which the head is located in Bologna and the body is at Dresden. Some 5th-centuryBCE torsos of Athena have been found at Athens. The torso of Athena in the École des Beaux-Arts at Paris, which has lost its head, gives some idea of what the original statue may have looked like. For the ancient Greeks, two works of Phidias far outshone all others: the colossal chryselephantine Statue of Zeus ( 432BCE) which was erected in the Temple of Zeus at Olympia, Greece, and the \"Athena Parthenos\" (lit. \"Athena the Virgin\"), a sculpture of the Greek virgin goddess Athena, which was housed in the Parthenon in Athens. Both sculptures belong to about the middle of the 5th century BCE. A number of replicas and works inspired by it, both ancient and modern, have been made. Upon completing the \"Athena Parthenos\", Phidias was accused of embezzlement. Specifically, he was charged with shortchanging the amount of gold that was supposed to be used for the statue and keeping the extra for himself. It seems that the charge was politically motivated a result of his friendship with Pericles, who had many enemies in Athens. Phidias supposedly weighed the gold robe of the \"Athena Parthenos\" to prove his innocence, but was then accused of impiously portraying himself and Pericles on the shield of the statue, which was apparently true. Plutarch records that Phidias was imprisoned and died in jail. Aristophanes' play \"Peace\" () mentions an unfortunate incident involving Phidias, but little context is provided. According to Philochorus, as quoted by a scholiast on Aristophanes, Phidias was put to death by the Eleans after he completed the Statue of Zeus at Olympia for them. From the late 5th century BCE, small copies of the statue of Zeus were found on coins from Elis, which give a general notion of the pose and the character of the head. The god was seated on a throne, every part of which was used for sculptural decoration. His body was of ivory, his robe of gold.

The officials of Pilsen founded a city-owned brewery in 1839, called (, – now Pilsner Urquell), which was to brew beer in the pioneering Bavarian style. Brewers had begun aging beer made with cool fermenting yeasts in caves (lager, i.e., [stored]), which improved the beer's clarity and shelf-life. Part of this research benefited from the knowledge already expounded on in a book (printed in German in 1794, in Czech in 1799), written by Czech brewer () (1753–1805) from Brno. The Pilsen brewery recruited the Bavarian brewer Josef Groll (1813–1887) who, using the specifics of local ingredients and paler malts, presented his first batch of pale lager on 5 October 1842. The combination of Pilsen's remarkably soft water, local Saaz noble hops from nearby Žatec, brighter malt prepared by British technology, and Bavarian-style lagering (bottom-fermented beer termed at the time) produced a clear, golden beer. The recipe was regarded as a sensation and took hold very quickly. Groll's contract with the brewery ended in 1845, he returned to Vilshofen and later inherited his father's brewery. The Groll brewery no longer exists. Parts of the brewery, however, were acquired by Wolferstetter, another brewery from Vilshofen, which still produces a Josef Groll Pils. Emergence of efficient glass manufacturing in Europe around the same time, lowered glass prices. This allowed the general population to purchase glass drinking vessels for the first time. These former luxury items showcased the visually pleasing golden clarity of the beer, further influencing the Pilsner's rapid dissemination. In 1853, the beer was available in 35 pubs in Prague. In 1856, it came to Vienna and in 1862 to Paris. Improving transport and communications also meant that this new beer was soon available throughout Europe, and the \"Pilsner\" style of brewing was soon widely imitated. In 1859, was registered as a brand name at the Chamber of Commerce and Trade in Pilsen.

Orthography is largely concerned with matters of spelling, and in particular the relationship between phonemes and graphemes in a language. Other elements that may be considered part of orthography include hyphenation, capitalization, word breaks, emphasis, and punctuation. Orthography thus describes or defines the set of symbols used in writing a language, and the rules regarding how to use those symbols. Most natural languages developed as oral languages, and writing systems have usually been crafted or adapted as ways of representing the spoken language. The rules for doing this tend to become standardized for a given language, leading to the development of an orthography that is generally considered \"correct\". In linguistics the term \"orthography\" is often used to refer to any method of writing a language, without judgment as to right and wrong, with a scientific understanding that orthographic standardization exists on a spectrum of strength of convention. The original sense of the word, though, implies a dichotomy of correct and incorrect, and the word is still most often used to refer specifically to a thoroughly standardized, prescriptively correct, way of writing a language.

For example, different forms of the letter \"b\" are all considered to represent a single grapheme in the orthography of, say, English. Graphemes or sequences of them are sometimes placed between angle brackets, as in or. This distinguishes them from phonemic transcription, which is placed between slashes (, ), and from phonetic transcription, which is placed between square brackets (, ).", "section_level": 1}, {"title": "Types.", "content": "The writing systems on which orthographies are based can be divided into a number of types, depending on what type of unit each symbol serves to represent. The principal types are \"logographic\" (with symbols representing words or morphemes), \"syllabic\" (with symbols representing syllables), and \"alphabetic\" (with symbols roughly representing phonemes). Many writing systems combine features of more than one of these types, and a number of detailed classifications have been proposed. Japanese is an example of a writing system that can be written using a combination of logographic kanji characters and syllabic hiragana and katakana characters; as with many non-alphabetic languages, alphabetic romaji characters may also be used as needed.", "section_level": 1}, {"title": "Correspondence with pronunciation.", "content": "Orthographies that use alphabets and syllabaries are based on the principle that the written symbols (graphemes) correspond to units of sound of the spoken language: phonemes in the former case, and syllables in the latter. However, in virtually all cases, this correspondence is not exact. Different languages' orthographies offer different degrees of correspondence between spelling and pronunciation. English orthography, French orthography and Danish orthography, for example, are highly irregular, whereas the orthographies of languages such as Russian, German and Spanish represent pronunciation much more faithfully, although the correspondence between letters and phonemes is still not exact. Finnish, Turkish and Serbo-Croatian orthographies are remarkably consistent: approximation of the principle \"one letter per sound\". An orthography in which the correspondences between spelling and pronunciation are highly complex or inconsistent is called a \"deep orthography\" (or less formally, the language is said to have \"irregular spelling\"). An orthography with relatively simple and consistent correspondences is called \"shallow\" (and the language has \"regular spelling\"). One of the main reasons for which spelling and pronunciation deviate is that sound changes taking place in the spoken language are not always reflected in the orthography, and hence spellings correspond to historical rather than present-day pronunciation. One consequence of this is that many spellings come to reflect a word's morphophonemic structure rather than its purely phonemic structure (for example, the English regular past tense morpheme is consistently spelled \"-ed\" in spite of its different pronunciations in various words). This is discussed further at. The syllabary systems of Japanese (hiragana and katakana) are examples of almost perfectly shallow orthographies—the kana correspond with almost perfect consistency to the spoken syllables, although with a few exceptions where symbols reflect historical or morphophonemic features: notably the use of ぢ \"ji\" and づ \"zu\" (rather than じ \"ji\" and ず \"zu\", their pronunciation in standard Tokyo dialect) when the character is a voicing of an underlying ち or つ (see rendaku), and the use of は, を, and へ to represent the sounds わ, お, and え, as relics of historical kana usage. The Korean \"hangul\" system was also originally an extremely shallow orthography, but as a representation of the modern language it frequently also reflects morphophonemic features.

Another is the digraph \"th\", which represents two different phonemes (as in \"then\" and \"thin\"). A more systematic example is that of abjads like the Arabic and Hebrew alphabets, in which the short vowels are normally left unwritten and must be inferred by the reader. When an alphabet is borrowed from its original language for use with a new language—as has been done with the Latin alphabet for many languages, or Japanese Katakana for non-Japanese words—it often proves defective in representing the new language's phonemes. Sometimes this problem is addressed by the use of such devices as digraphs (such as \"sh\" and \"ch\" in English, where pairs of letters represent single sounds), diacritics (like the caron on the letters \"š\" and \"č\", which represent those same sounds in Czech), or the addition of completely new symbols (as some languages have introduced the letter \"w\" to the Latin alphabet) or of symbols from another alphabet, such as the rune \"þ\" in Icelandic. After the classical period, Greek developed a lowercase letter system that introduced diacritic marks to enable foreigners to learn pronunciation and in some cases, grammatical features.

The herb then made its way east to China and was naturalized there as early as 220 AD, during the late Han Dynasty. Rosemary came to England at an unknown date; the Romans probably brought it when they invaded in the first century, but there are no viable records about rosemary arriving in Britain until the 8th century. This was credited to Charlemagne, who promoted herbs in general, and ordered rosemary to be grown in monastic gardens and farms. Furthermore, there are also no records of rosemary being properly naturalized in Britain until 1338, when cuttings were sent by The Countess of Hainault, Jeanne of Valois (1294–1342) to Queen Phillippa (1311–1369), wife of Edward III.

The rice is first cooked briefly in a \"soffritto\" of onion and butter or olive oil, to coat each grain in a film of fat, called \"tostatura\"; white wine is added and must be absorbed by the grains. When it has been absorbed the heat is raised to medium high, and boiling stock is gradually added in small amounts, while stirring constantly. The constant stirring, with only a small amount of liquid present, forces the grains to rub against each other and release the starch from the outside of the grains into the surrounding liquid, creating a smooth creamy-textured mass. When the rice is cooked the pot is taken off the heat for \"mantecatura\", vigorously beating in refrigerated balls of grated parmesan cheese and butter, to make the texture as creamy and smooth as possible. It may be removed from the heat a few minutes earlier and left to cook with its residual heat. Properly cooked risotto is rich and creamy even if no cream is added, due to the starch in the grains.

Navigation at sea was done by eye until around 1500 when navigational instruments were developed and cartographers began using a coordinate system with parallels of latitude and meridians of longitude. By the late 16th century, Englishmen knew that the ratio of distances at sea to degrees were constant along any great circle such as the equator or any meridian, assuming that Earth was a sphere. Robert Hues wrote in 1594 that the distance along a great circle was 60 miles per degree, that is, one nautical mile per arcminute. Edmund Gunter wrote in 1623 that the distance along a great circle was 20 leagues per degree. Thus, Hues explicitly used nautical miles while Gunter did not. Since the Earth is not a perfect sphere but is an oblate spheroid with slightly flattened poles, a minute of latitude is not constant, but about 1861 metres at the poles and 1843 metres at the Equator. France and other metric countries state that in principle a nautical mile is an arcminute of a meridian at a latitude of 45°, but that is a modern justification for a more mundane calculation that was developed a century earlier. By the mid 19th century France had defined a nautical mile via the original 1791 definition of the metre, one ten-millionth of a quarter meridian. Thus became the metric length for a nautical mile. France made it legal for the French Navy in 1906, and many metric countries voted to sanction it for international use at the 1929 International Hydrographic Conference.

Being forced to pay for his living expenses from an early age, he decided against attending a university and worked for the \"Deutsche Reichspost\", the postal system of the German Empire. Dissatisfied, he began an apprenticeship to his merchant brother in Berlin. Then he lived in Málaga, Spain for two years, working as a correspondent. He then returned to Berlin involuntarily to complete his military service. After this, he worked as a merchant in Brunswick and Hamburg. In 1887, Gesell relocated to Buenos Aires, Argentina, where he opened a franchise of his brother's business. The 1890 depression in Argentina, which hurt his business considerably, caused him to think about the structural problems caused by the monetary system. In 1891, he released his first writing on this topic: \"Die Reformation des Münzwesens als Brücke zum sozialen Staat\" (\"The Reformation of the Monetary System as a Bridge to a Social State\"). He then wrote \"Nervus Rerum\" and \"The Nationalization of Money\". He gave his business to his brother and returned to Europe in 1892. After a stay in Germany, Gesell relocated to Les Hauts-Geneveys in the Swiss canton of Neuchâtel. He farmed in order to support himself while continuing his economic studies. In 1900, he created the magazine \"Geld- und Bodenreform\" (\"Monetary and Land Reform\"), but it failed in 1903 for financial reasons.

But his land reform proposal was different from Georgism. He believed that taxes could not solve the problem of rent on land, as taxes could be transferred to tenants. He thought we must abolish the private ownership of land and put free-land reform, a sort of public lease of land, into effect. According to Silvio Gesell, it is not effective to establish welfare systems without abolishing private ownership of land because the proceeds of the labor of workers are determined by the proceeds of labor that they can obtain on free land. The benefits gained by the welfare system are not to increase the proceeds of labor that workers can obtain on free land, but rather to increase the proceeds of labor that they can obtain on the lands of landowners. Private ownership of land converts all the advantages of using one's land into cash and it belongs to the landowner. In order not to cancel the effects of welfare policies, Silvio Gesell's Free-Land reform is needed. Gesell based his economic thought on the self-interest of individuals, which he saw as a \"natural\" and healthy motive, in satisfying their needs and being productive. Gesell believed that an economic system must do justice to individual proclivities; otherwise the system would fail. He believed that this stance put him in opposition to Marxism, which, Gesell considered, proposed an economic system that was against human nature. Believing that the talent and selfishness of individuals must be taken into account, Gesell called for free, fair business competition, with equal chances for all. This included the removal of all legal and inherited privilege. Everyone should rely only on their abilities to make a living. In the \"natural economic order\" which Gesell recommended, the most talented people would have the greatest income, without distortion by interest and rent charges. The economic status of the less-talented would improve because they would not be forced to pay interest and rent charges. According to Gesell, this would result in less difference between the poor and the rich. Furthermore, greater average incomes would mean that the poor would have a greater chance of escaping poverty, in part because other poor people would have greater disposable income and spending power. Some regard Gesell's idea as a negative interest rate policy. The difference between them is that, with the free-money reforms of Gesell, hoarding money becomes impossible because the face-value of money is depreciated regularly. This forces the circulation of money. With negative interest, on the contrary, there is the possibility of hoarding money because the face value of money is constant and people can use their money as a means of saving. For example, Japan's negative interest rates are driving up the sales of safes and strongboxes. Gesell denied value theory in economics.

The fourth vertex is not shared with another tetrahedron and all of the tetrahedra \"point\" in the same direction; i.e. all of the unshared vertices are on the same side of the sheet. In clays, the tetrahedral sheets are always bonded to octahedral sheets formed from small cations, such as aluminum or magnesium, and coordinated by six oxygen atoms. The unshared vertex from the tetrahedral sheet also forms part of one side of the octahedral sheet, but an additional oxygen atom is located above the gap in the tetrahedral sheet at the center of the six tetrahedra. This oxygen atom is bonded to a hydrogen atom forming an OH group in the clay structure. Clays can be categorized depending on the way that tetrahedral and octahedral sheets are packaged into \"layers\". If there is only one tetrahedral and one octahedral group in each layer the clay is known as a 1:1 clay. The alternative, known as a 2:1 clay, has two tetrahedral sheets with the unshared vertex of each sheet pointing towards each other and forming each side of the octahedral sheet. Bonding between the tetrahedral and octahedral sheets requires that the tetrahedral sheet becomes corrugated or twisted, causing ditrigonal distortion to the hexagonal array, and the octahedral sheet is flattened. This minimizes the overall bond-valence distortions of the crystallite. Depending on the composition of the tetrahedral and octahedral sheets, the layer will have no charge or will have a net negative charge.

Parallel to agriculture-directed studies, more basic scientific research elucidated many of viroids' physical, chemical, and macromolecular properties. Viroids were shown to consist of short stretches (a few hundred nucleobases) of single-stranded RNA and, unlike viruses, did not have a protein coat. Compared with other infectious plant pathogens, viroids are extremely small in size, ranging from 246 to 467 nucleobases; they thus consist of fewer than 10,000 atoms. In comparison, the genomes of the smallest known viruses capable of causing an infection by themselves are around 2,000 nucleobases long. In 1976, Sänger et al. presented evidence that potato spindle tuber viroid is a \"single-stranded, covalently closed, circular RNA molecule, existing as a highly base-paired rod-like structure\"—believed to be the first such molecule described. Circular RNA, unlike linear RNA, forms a covalently closed continuous loop, in which the 3' and 5' ends present in linear RNA molecules have been joined together. Sänger et al. also provided evidence for the true circularity of viroids by finding that the RNA could not be phosphorylated at the 5' terminus. Then, in other tests, they failed to find even one free 3' end, which ruled out the possibility of the molecule having two 3' ends. Viroids thus are true circular RNAs. The single-strandedness and circularity of viroids was confirmed by electron microscopy, and Gross et al. determined the complete nucleotide sequence of potato spindle tuber viroid in 1978. PSTVd was the first pathogen of a eukaryotic organism for which the complete molecular structure has been established. Over thirty plant diseases have since been identified as viroid-, not virus-caused, as had been assumed.

Seeking to outdo their Athenian rivals, the Eleans employed the renowned sculptor Phidias, who had previously made the massive statue of Athena Parthenos in the Parthenon. The statue occupied half the width of the aisle of the temple built to house it. \"It seems that if Zeus were to stand up,\" the geographer Strabo noted early in the 1st century BC, \"he would unroof the temple.\" The \"Zeus\" was a chryselephantine sculpture, made with ivory and gold panels on a wooden substructure. No copy in marble or bronze has survived, though there are recognizable but only approximate versions on coins of nearby Elis and on Roman coins and engraved gems. The 2nd-century AD geographer and traveler Pausanias left a detailed description: the statue was crowned with a sculpted wreath of olive sprays and wore a gilded robe made from glass and carved with animals and lilies. Its right hand held a small chryselephantine statue of crowned Nike, goddess of victory; its left a scepter inlaid with many metals, supporting an eagle. The throne featured painted figures and wrought images and was decorated with gold, precious stones, ebony, and ivory. Zeus' golden sandals rested upon a footstool decorated with an Amazonomachy in relief. The passage underneath the throne was restricted by painted screens. Pausanias also recounts that the statue was kept constantly coated with olive oil to counter the harmful effect on the ivory caused by the \"marshiness\" of the Altis grove. The floor in front of the image was paved with black tiles and surrounded by a raised rim of marble to contain the oil. This reservoir acted as a reflecting pool which doubled the apparent height of the statue. According to the Roman historian Livy, the Roman general Aemilius Paulus (the victor over Macedon) saw the statue and \"was moved to his soul, as if he had seen the god in person,\" while the 1st-centuryAD Greek orator Dio Chrysostom declared that a single glimpse of the statue would make a man forget all his earthly troubles. According to a legend, when Phidias was asked what inspired him—whether he climbed Mount Olympus to see Zeus, or whether Zeus came down from Olympus so that Phidias could see him—the artist answered that he portrayed Zeus according to Book One, verses 528 – 530 of Homer's \"Iliad\": The sculptor also was reputed to have immortalised Pantarkes, the winner of the boys' wrestling event at the eighty-sixth Olympiad who was said to have been his \"beloved\" (eromenos), by carving \"Pantarkes kalos\" (\"Pantarkes is beautiful\") into Zeus's little finger, and by placing a relief of the boy crowning himself at the feet of the statue.

The sanctuary at Olympia fell into disuse. The circumstances of the statue's eventual destruction are unknown.

Many tropical areas have a dry and wet season. The wet season, rainy season or green season is the time of year, ranging from one or more months, when most of the average annual rainfall in a region falls. Areas with wet seasons are disseminated across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet-season month is defined as a month where average precipitation is or more. Tropical rainforests technically do not have dry or wet seasons, since their rainfall is equally distributed through the year. Some areas with pronounced rainy seasons see a break in rainfall during mid-season when the intertropical convergence zone or monsoon trough moves poleward of their location during the middle of the warm season; typical vegetation in these areas ranges from moist seasonal tropical forests to savannahs. When the wet season occurs during the warm season, or summer, precipitation falls mainly during the late afternoon and early evening hours. The wet season is a time when air quality improves, freshwater quality improves and vegetation grows significantly, leading to crop yields late in the season. Floods cause rivers to overflow their banks, and some animals to retreat to higher ground. Soil nutrients diminish and erosion increases. The incidence of malaria increases in areas where the rainy season coincides with high temperatures. Animals have adaptation and survival strategies for the wetter regime. The previous dry season leads to food shortages into the wet season, as the crops have yet to mature. However, regions within the tropics may well not have a tropical climate. Under the Köppen climate classification, much of the area within the geographical tropics is classed not as \"tropical\" but as \"dry\" (arid or semi-arid), including the Sahara Desert, the Atacama Desert and Australian Outback.

Some examples of important biodiversity and high endemism ecosystems are El Yunque National Forest in Puerto Rico, Costa Rican and Nicaraguan rainforests, Amazon Rainforest territories of several South American countries, Madagascar dry deciduous forests, the Waterberg Biosphere of South Africa, and eastern Madagascar rainforests. Often the soils of tropical forests are low in nutrient content, making them quite vulnerable to slash-and-burn deforestation techniques, which are sometimes an element of shifting cultivation agricultural systems. In biogeography, the tropics are divided into Paleotropics (Africa, Asia and Australia) and Neotropics (Caribbean, Central America, and South America).

Tropicality encompassed two images. One, is that the tropics represent a 'Garden of Eden', a heaven on Earth, a land of rich biodiversity - aka a tropical paradise. The alternative is that the tropics consist of wild, unconquerable nature. The latter view was often discussed in old Western literature more so than the first. Evidence suggests over time that the view of the tropics as such in popular literature has been supplanted by more well-rounded and sophisticated interpretations. Western scholars tried to theorize reasons about why tropical areas were relatively more inhospitable to human civilisations then those existing in colder regions of the Northern Hemisphere. A popular explanation focused on the differences in climate. Tropical jungles and rainforests have much more humid and hotter weather than colder and drier temperaments of the Northern Hemisphere. This theme led to some scholars to suggest that humid hot climates correlate to human populations lacking control over nature e.g.'the wild Amazonian rainforests'.", "section_level": 1}], "src_summary": "The tropics is the region of the Earth surrounding the Equator.

He became an artist without having had any exposure to the art world, drawing much inspiration from art magazines. In 1910, Rodchenko began studies under Nicolai Fechin and Georgii Medvedev at the Kazan Art School, where he met Varvara Stepanova, whom he later married. After 1914, he continued his artistic training at the Stroganov Institute in Moscow, where he created his first abstract drawings, influenced by the Suprematism of Kazimir Malevich, in 1915. The following year, he participated in \"The Store\" exhibition organized by Vladimir Tatlin, who was another formative influence. Rodchenko's work was heavily influenced by Cubism and Futurism, as well as by Malevich's Suprematist compositions, which featured geometric forms deployed against a white background. While Rodchenko was a student of Tatlin's he was also his assistant, and the interest in figuration that characterized Rodchenko's early work disappeared as he experimented with the elements of design. He utilized a compass and ruler in creating his paintings, with the goal of eliminating expressive brushwork. Rodchenko worked in Narkompros and he was one of the organizers of RABIS. RABIS was formed in 1919–1920. Rodchenko was appointed Director of the Museum Bureau and Purchasing Fund by the Bolshevik Government in 1920, responsible for the reorganization of art schools and museums. He became secretary of the Moscow Artists' Union and set up the Fine Arts Division of the People's Commissariat for Education, and helped found the Institute for Artistic Culture. He taught from 1920 to 1930 at the Higher Technical-Artistic Studios (VKhUTEMAS/VKhUTEIN), a Bauhaus organization with a \"checkered career\". It was disbanded in 1930. In 1921 he became a member of the Productivist group, with Stepanova and Aleksei Gan, which advocated the incorporation of art into everyday life. He gave up painting in order to concentrate on graphic design for posters, books, and films. He was deeply influenced by the ideas and practice of the filmmaker Dziga Vertov, with whom he worked intensively in 1922. Impressed by the photomontage of the German Dadaists, Rodchenko began his own experiments in the medium, first employing found images in 1923, and from 1924 on, shooting his own photographs as well. His first published photomontage illustrated Mayakovsky's poem, \"About This\", in 1923. In 1924, Rodchenko produced what is likely his most famous poster, an advertisement for the Lengiz Publishing House sometimes titled \"Books\", which features a young woman with a cupped hand shouting \"книги по всем отраслям знания\" (Books in all branches of knowledge), printed in modernist typography. From 1923 to 1928 Rodchenko collaborated closely with Mayakovsky (of whom he took several portraits) on the design and layout of LEF and \"Novy LEF\", the publications of Constructivist artists. Many of his photographs appeared in or were used as covers for these and other journals. His images eliminated unnecessary detail, emphasized dynamic diagonal composition, and were concerned with the placement and movement of objects in space. During this period, he and Stepanova painted the well-known panels of the Mosselprom building in Moscow. Their daughter, Varvara Rodchenko, was born in 1925. Throughout the 1920s, Rodchenko's work was very abstract. Rodchenko joined the October Group of artists in 1928 but was expelled three years later, charged with \"formalism\", an accusation first raised in the pages of Sovetskoe Foto in 1928. In the 1930s, with the changing Party guidelines governing artistic practice in favour of Socialist Realism, he concentrated on sports photography and images of parades and other choreographed movements. He returned to painting in the late 1930s, stopped photographing in 1942, and produced abstract expressionist works in the 1940s.

Early characteristics of seed plants were evident in fossil progymnosperms of the late Devonian period around 383 million years ago. It has been suggested that during the mid-Mesozoic era, pollination of some extinct groups of gymnosperms was by extinct species of scorpionflies that had specialized proboscis for feeding on pollination drops. The scorpionflies likely engaged in pollination mutualisms with gymnosperms, long before the similar and independent coevolution of nectar-feeding insects on angiosperms.

Pollen grains (microgametophytes) mature from microspores, and ultimately produce sperm cells. Megagametophytes develop from megaspores and are retained within the ovule. Gymnosperms produce multiple archegonia, which produce the female gamete. During pollination, pollen grains are physically transferred between plants from the pollen cone to the ovule. Pollen is usually moved by wind or insects. Whole grains enter each ovule through a microscopic gap in the ovule coat (integument) called the micropyle. The pollen grains mature further inside the ovule and produce sperm cells. Two main modes of fertilization are found in gymnosperms. Cycads and \"Ginkgo\" have motile sperm that swim directly to the egg inside the ovule, whereas conifers and gnetophytes have sperm with no flagella that are moved along a pollen tube to the egg.

His father's family was of Italian descent. His sister was writer Bettina von Arnim, who, at a young age, lionised and corresponded with Goethe, and, in 1835, published the correspondence as \"Goethes Briefwechsel mit einem Kinde\" (Goethe's correspondence with a child). Clemens Brentano studied in Halle and Jena, afterwards residing at Heidelberg, Vienna and Berlin. He was close to Wieland, Herder, Goethe, Friedrich Schlegel, Fichte and Tieck. From 1798 to 1800 Brentano lived in Jena, the first center of the romantic movement. In 1801, he moved to Göttingen, and became a friend of Achim von Arnim. He married writer Sophie Mereau on 29 October 1803. In 1804, he moved to Heidelberg and worked with Arnim on \"Zeitungen für Einsiedler\" and \"Des Knaben Wunderhorn\". After his wife Sophie died in 1806 he married a second time in 1807 to Auguste Bussmann (whose half-sister, Marie de Flavigny, later by marriage the Countess Marie d'Agoult, would become the companion of pianist and composer Franz Liszt). In the years between 1808 and 1818, Brentano lived mostly in Berlin, and from 1819 to 1824 in Dülmen, Westphalia. In 1818, weary of his somewhat restless and unsettled life, he returned to the practice of the Catholic faith and withdrew to the monastery of Dülmen, where he lived for some years in strict seclusion. He took on there the position of secretary to the Catholic visionary nun, the Blessed Anne Catherine Emmerich. It was claimed that from 1802 until her death, she bore the wounds of the Crown of Thorns, and from 1812, the full stigmata, a cross over her heart and the wound from the lance. Clemens Brentano made her acquaintance in 1818 and remained at the foot of the stigmatist's bed copying her dictation until 1824. When she died, he prepared an index of the visions and revelations from her journal, \"The Dolorous Passion of Our Lord Jesus Christ\" (published 1833). One of these visions made known by Brentano later resulted in the actual identification of the real House of the Virgin Mary in Ephesus by Abbé Julien Gouyet, a French priest, during 1881. However, some posthumous investigations in 1923 and 1928 made it uncertain how much of the books he attributed to Emmerich were actually his own creation and the works were discarded for her beatification process. The latter part of his life he spent in Regensburg, Frankfurt and Munich, actively engaged in promoting the Catholic faith. Brentano assisted Ludwig Achim von Arnim, his brother-in-law, in the collection of folk-songs forming \"Des Knaben Wunderhorn\" (1805–1808), which Gustav Mahler drew upon for his song cycle. He died in Aschaffenburg. Brentano, whose early writings were published under the pseudonym Maria, belonged to the Heidelberg group of German romantic writers, and his works are marked by excess of fantastic imagery and by abrupt, bizarre modes of expression.

Having finished school, he began an apprenticeship at a bank, but already took acting lessons. In 1890, he gave his debut on a private stage in Vienna with the stage name \"Max Reinhardt\" (possibly after the protagonist Reinhard Werner in Theodor Storm's novella \"Immensee\"). In 1893 he performed at the re-opened Salzburg City Theatre. One year later, Reinhardt relocated to Germany, joining the Deutsches Theater ensemble under director Otto Brahm in Berlin. In 1918 Reinhardt purchased Schloss Leopoldskron castle in Salzburg, which had fallen into disrepair. While living in it for nearly 20 years, he painstakingly restored the castle; however he fled due to the Nazis' increasing anti-Semitic aggressions. The castle was seized following Germany's Anschluss annexation of Austria in 1938.

From 1903 to 1905, he managed the Neues Theater (present-day Theater am Schiffbauerdamm) and in 1906 acquired the Deutsches Theater in Berlin. In 1911, he premiered with Karl Vollmöller's \"The Miracle\" in Olympia, London, gaining an international reputation. In 1910, Siegfried Jacobsohn wrote his book entitled \"Max Reinhardt\". In 1914, he was persuaded to sign the Manifesto of the Ninety-Three, defending the German invasion of Belgium. He was signatory 66; he later expressed regret at signing. From 1915 to 1918, Reinhardt also worked as director of the Volksbühne theatre and after World War I re-opened the Großes Schauspielhaus (after World War II renamed into Friedrichstadtpalast) in 1919, following its expressionist conversion by Hans Poelzig. By 1930, he ran eleven stages in Berlin and, in addition, managed the Theater in der Josefstadt in Vienna from 1924 to 1933. In 1920, Reinhardt established the Salzburg Festival with Richard Strauss and Hugo von Hofmannsthal, notably directing an annual production of the morality play \"Jedermann\" in which God sends Death to summon a representative of mankind for judgment. In the United States, he successfully directed \"The Miracle\" in 1924, and a popular stage version of Shakespeare's \"A Midsummer Night's Dream\" in 1927. Reinhardt followed that success by directing a film version of A Midsummer Night's Dream in 1935 using a mostly different cast, that included James Cagney, Mickey Rooney, Joe E. Brown and Olivia de Havilland, amongst others. Mickey Rooney and Olivia de Havilland had also appeared in Reinhardt's 1934 stage production, which was staged at the Hollywood Bowl. The Nazis banned the film because of the Jewish ancestry of both Reinhardt and Felix Mendelssohn, whose music (arranged by Erich Wolfgang Korngold) was used throughout the film. After the Anschluss of Austria to Nazi-governed Germany in 1938, he emigrated first to Britain, then to the United States. Reinhardt opened the Reinhardt School of the Theatre in Hollywood, on Sunset Boulevard. Several notable stars of the day received classical theater training, among them actress Nanette Fabray. In 1940, he became a naturalized citizen of the United States. At that time, he was married to his second wife, actress Helene Thimig, daughter of actor Hugo Thimig. By employing powerful staging techniques, and integrating stage design, language, music and choreography, Reinhardt introduced new dimensions into German theatre.

He made films as a director and from time to time also as a producer. His first staging was the film \"Sumurûn\" in 1910. After that, Reinhardt founded his own film company. He sold the film rights for the film adaptation of the play \"Das Mirakel\" (\"The Miracle\") to Joseph Menchen, whose full-colour 1912 film of \"The Miracle\" gained world-wide success. Controversies around the staging of \"Das Mirakel\", which was shown in the Vienna Rotunde in 1912, led to Reinhardt's retreat from the project. The author of the play, Reinhardt's friend and confidant Karl Gustav Vollmoeller, had French director Michel Carré finish the shooting. Reinhardt made two films, \"Die Insel der Seligen\" (\"Isle of the Blessed\") and \"Eine venezianische Nacht\" (\"Venetian Nights\"), under a four-picture contract for the German film producer Paul Davidson. Released in 1913 and 1914, respectively, both films received negative reviews from the press and public. The other two films called for in the contract were never made. Both films demanded much of cameraman Karl Freund because of Reinhardt's special shooting needs, such as filming a lagoon in moonlight. \"Isle of the Blessed\" attracted attention due to its erotic nature. Its ancient mythical setting included sea gods, nymphs, and fauns, and the actors appeared naked. However, the film also fit in with the strict customs of the late German and Austrian empires. The actors had to live up to the demands of double roles. Wilhelm Diegelmann and Willy Prager played the bourgeois fathers as well as the sea gods, a bachelor and a faun, Leopoldine Konstantin the Circe. The shooting for \"Eine venezianische Nacht\" by Karl Gustav Vollmoeller took place in Venice. Maria Carmi played the bride, Alfred Abel the young stranger, and Ernst Matray Anselmus and Pipistrello. The shooting was disturbed by a fanatic who incited the attendant Venetians against the German-speaking staff. In 1935, Reinhardt directed his first film in the US, \"A Midsummer Night's Dream\".

The embryos of Pinaceae have three to 24 cotyledons. The female cones are large and usually woody, long, with numerous spirally arranged scales, and two winged seeds on each scale. The male cones are small, long, and fall soon after pollination; pollen dispersal is by wind. Seed dispersal is mostly by wind, but some species have large seeds with reduced wings, and are dispersed by birds. Analysis of Pinaceae cones reveals how selective pressure has shaped the evolution of variable cone size and function throughout the family. Variation in cone size in the family has likely resulted from the variation of seed dispersal mechanisms available in their environments over time. All Pinaceae with seeds weighing less than 90 mg are seemingly adapted for wind dispersal. Pines having seeds larger than 100 mg are more likely to have benefited from adaptations that promote animal dispersal, particularly by birds. Pinaceae that persist in areas where tree squirrels are abundant do not seem to have evolved adaptations for bird dispersal. Boreal conifers have many adaptions for winter.

In a 1910 publication, the family was divided into two tribes based on the occurrence and type of long–short shoot dimorphism. A more recent classification divided the subfamilies and genera based on the consideration of features of ovulate cone anatomy among extant and fossil members of the family.

They are produced and stored in specialized secretory areas known as resin ducts, resin blisters, or resin cavities. Resins have the ability to wash away, trap, fend off antagonists, and are also involved in wound sealing. They are an effective defense mechanism because they have toxic and inhibitory effects on invaders, such as insects or pathogens. Resins could have developed as an evolutionary defense against bark beetle attacks. One well researched resin present in \"Pinaceae\" is oleoresin.

The area under the curve will be: which is the amount of thermal energy transferred in the process. If the process moves to greater entropy, the area under the curve will be the amount of heat absorbed by the system in that process. If the process moves towards lesser entropy, it will be the amount of heat removed. For any cyclic process, there will be an upper portion of the cycle and a lower portion. For a clockwise cycle, the area under the upper portion will be the thermal energy absorbed during the cycle, while the area under the lower portion will be the thermal energy removed during the cycle. The area inside the cycle will then be the difference between the two, but since the internal energy of the system must have returned to its initial value, this difference must be the amount of work done by the system over the cycle. Referring to, mathematically, for a reversible process we may write the amount of work done over a cyclic process as: Since \"dU\" is an exact differential, its integral over any closed loop is zero and it follows that the area inside the loop on a T–S diagram is equal to the total work performed if the loop is traversed in a clockwise direction, and is equal to the total work done on the system as the loop is traversed in a counterclockwise direction.", "section_level": 2}, {"title": "The Carnot cycle.", "content": "Evaluation of the above integral is particularly simple for the Carnot cycle.

That is all the processes that compose it can be reversed, in which case it becomes the Carnot refrigeration cycle. This time, the cycle remains exactly the same except that the directions of any heat and work interactions are reversed. Heat is absorbed from the low-temperature reservoir, heat is rejected to a high-temperature reservoir, and a work input is required to accomplish all this. The P–V diagram of the reversed Carnot cycle is the same as for the Carnot cycle except that the directions of the processes are reversed.", "section_level": 2}, {"title": "Carnot's theorem.", "content": "It can be seen from the above diagram, that for any cycle operating between temperatures formula_13 and formula_12, none can exceed the efficiency of a Carnot cycle. Carnot's theorem is a formal statement of this fact: \"No engine operating between two heat reservoirs can be more efficient than a Carnot engine operating between those same reservoirs.\" Thus, Equation gives the maximum efficiency possible for any engine using the corresponding temperatures. A corollary to Carnot's theorem states that: \"All reversible engines operating between the same heat reservoirs are equally efficient.\" Rearranging the right side of the equation gives what may be a more easily understood form of the equation, namely that the theoretical maximum efficiency of a heat engine equals the difference in temperature between the hot and cold reservoir divided by the absolute temperature of the hot reservoir. Looking at this formula an interesting fact becomes apparent: Lowering the temperature of the cold reservoir will have more effect on the ceiling efficiency of a heat engine than raising the temperature of the hot reservoir by the same amount. In the real world, this may be difficult to achieve since the cold reservoir is often an existing ambient temperature. In other words, maximum efficiency is achieved if and only if no new entropy is created in the cycle, which would be the case if e.g. friction leads to dissipation of work into heat. In that case, the cycle is not reversible and the Clausius theorem becomes an inequality rather than an equality. Otherwise, since entropy is a state function, the required dumping of heat into the environment to dispose of excess entropy leads to a (minimal) reduction in efficiency. So Equation gives the efficiency of any reversible heat engine. In mesoscopic heat engines, work per cycle of operation in general fluctuates due to thermal noise. If the cycle is performed quasi-statically, the fluctuations vanish even on the mesoscale. However, if the cycle is performed faster than the relaxation time of the working medium, the fluctuations of work are inevitable. Nevertheless, when work and heat fluctuations are counted, there is exact equality that relates the exponential average of work performed by any heat engine and the heat transfer from the hotter heat bath.", "section_level": 2}, {"title": "Efficiency of real heat engines.", "content": "Carnot realized that in reality it is not possible to build a thermodynamically reversible engine, so real heat engines are even less efficient than indicated by Equation 3. In addition, real engines that operate along this cycle are rare. Nevertheless, Equation 3 is extremely useful for determining the maximum efficiency that could ever be expected for a given set of thermal reservoirs. Although Carnot's cycle is an idealisation, the expression of Carnot efficiency is still useful. Consider the average temperatures, at which heat is input and output, respectively. Replace \"T\" and \"T\" in Equation () by 〈\"T\"〉 and 〈\"T\"〉 respectively. For the Carnot cycle, or its equivalent, the average value 〈\"T\"〉 will equal the highest temperature available, namely \"T\", and 〈\"T\"〉 the lowest, namely \"T\". For other less efficient cycles, 〈\"T\"〉 will be lower than \"T\", and 〈\"T\"〉 will be higher than \"T\". This can help illustrate, for example, why a reheater or a regenerator can improve the thermal efficiency of steam power plants—and why the thermal efficiency of combined-cycle power plants (which incorporate gas turbines operating at even higher temperatures) exceeds that of conventional steam plants.

However, he supposedly surrendered this out of a fear that they would hinder his search for knowledge. The Roman author Valerius Maximus preserves a different tradition: Anaxagoras, coming home from a long voyage, found his property in ruin, and said: \"If this had not perished, I would have\"—a sentence described by Valerius as being \"possessed of sought-after wisdom!\" Anaxagoras was a Greek citizen of the Persian Empire and had served in the Persian army; he may have been a member of the Persian regiments that entered mainland Greece during the Greco-Persian Wars. Though this remains uncertain, \"it would certainly explain why he came to Athens in the year of Salamis, 480/79 B.C.\" Anaxagoras is said to have remained in Athens for thirty years. Pericles learned to love and admire him, and the poet Euripides derived from him an enthusiasm for science and humanity. Anaxagoras brought philosophy and the spirit of scientific inquiry from Ionia to Athens. His observations of the celestial bodies and the fall of meteorites led him to form new theories of the universal order, and to prediction of the impact of meteorites. Plutarch says \"Anaxagoras is said to have predicted that if the heavenly bodies should be loosened by some slip or shake, one of them might be torn away, and might plunge and fall down to earth\". According to Pliny he was credited with predicting the fall of the meteorite in 467. He attempted to give a scientific account of eclipses, meteors, rainbows, and the Sun, which he described as a mass of blazing metal, larger than the Peloponnese; his theories about eclipses, the Sun and Moon may well have been based on observations of the eclipse of 463 BCE, which was visible in Greece. He was the first to explain that the Moon shines due to reflected light from the Sun. He also said that the Moon had mountains and believed that it was inhabited. The heavenly bodies, he asserted, were masses of stone torn from the Earth and ignited by rapid rotation. He was the first to give a correct explanation of eclipses, and was both famous and notorious for his scientific theories, including the claims that the Sun is a mass of red-hot metal, that the Moon is earthy, and that the stars are fiery stones. He thought the Earth was flat and floated supported by'strong' air under it and disturbances in this air sometimes caused earthquakes. These speculations made him vulnerable in Athens to a charge of impiety. Diogenes Laërtius reports the story that he was prosecuted by Cleon for impiety, but Plutarch says that Pericles sent his former tutor, Anaxagoras, to Lampsacus for his own safety after the Athenians began to blame him for the Peloponnesian war. The charges against Anaxagoras may have stemmed from his denial of the existence of a solar or lunar deity. According to Laërtius, Pericles spoke in defense of Anaxagoras at his trial,. Even so, Anaxagoras was forced to retire from Athens to Lampsacus in Troad (433). He died there in around the year 428. Citizens of Lampsacus erected an altar to Mind and Truth in his memory, and observed the anniversary of his death for many years.

Word separators (typically spaces) are common in modern orthography of languages using alphabetic scripts, but these are (excepting isolated precedents) a relatively modern development (see also history of writing). In English orthography, compound expressions may contain spaces. For example, \"ice cream\", \"air raid shelter\" and \"get up\" each are generally considered to consist of more than one word (as each of the components are free forms, with the possible exception of \"get\"). Not all languages delimit words expressly. Mandarin Chinese is a very analytic language (with few inflectional affixes), making it unnecessary to delimit words orthographically. However, there are many multiple-morpheme compounds in Mandarin, as well as a variety of bound morphemes that make it difficult to clearly determine what constitutes a word. Sometimes, languages which are extremely close grammatically will consider the same order of words in different ways. For example, reflexive verbs in the French infinitive are separate from their respective particle, e.g. \"se laver\" (\"to wash oneself\"), whereas in Portuguese they are hyphenated, e.g. \"lavar-se\", and in Spanish they are joined, e.g. \"lavarse\". Japanese uses orthographic cues to delimit words such as switching between kanji (Chinese characters) and the two kana syllabaries. This is a fairly soft rule, because content words can also be written in hiragana for effect (though if done extensively spaces are typically added to maintain legibility).

Wittgenstein's thought transitioned from a word as representation of meaning to \"the meaning of a word is its use in the language.\" Archaeology shows that even for centuries prior to this fascination by philosophers in the 5th century BC, many languages had various ways of expressing this verbal unit, which in turn diversified and evolved into a range of expressions with wide philosophical significance.

Beginning with the reality of disaster, Lamentations concludes with the bitter possibility that God may have finally rejected Israel (chapter 5:22). Sufferers in the face of grief are not urged to a confidence in the goodness of God; in fact God is accountable for the disaster. The poet acknowledges that this suffering is a just punishment, still God is held to have had choice over whether to act in this way and at this time. Hope arises from a recollection of God's past goodness, but although this justifies a cry to God to act in deliverance, there is no guarantee that he will. Repentance will not persuade God to be gracious, since he is free to give or withhold grace as he chooses.

In August, Soviet and other Warsaw Pact troops invaded Czechoslovakia. This led to the overthrow of Dubček and to what came to be known as the normalization process. Less than a month after the invasion, Plastic People of the Universe was formed. Bassist Milan Hlavsa formed the band in 1968 and was heavily influenced by Frank Zappa and the Velvet Underground (Zappa's band, the Mothers of Invention, had a song called \"Plastic People\" from their 1967 album \"Absolutely Free\"). Czech art historian and cultural critic Ivan Jirous became their manager/artistic director in the following year, fulfilling a role similar to the one Andy Warhol had with the Velvet Underground. Jirous introduced Hlavsa to guitarist Josef Janíček, and viola player Jiří Kabeš. The consolidated Czech communist government revoked the band's musicians license in 1970. Because Ivan Jirous believed that English was the lingua franca of rock music, he invited Paul Wilson, a Canadian who had been teaching in Prague, to teach the band the lyrics of the American songs they covered and to translate their original Czech lyrics into English. Wilson served as lead singer for \"the Plastics\" from 1970 to 1972, and during this time, the band's repertoire drew heavily on songs by the Velvet Underground and the Fugs. The only two songs sung in Czech in this period were \"Na sosnové větvi\" and \"Růže a mrtví\", lyrics of both being written by Czech poet Jiří Kolář. Wilson encouraged them to sing in Czech. After he left, saxophonist Vratislav Brabenec joined the band and they began to draw upon poet Egon Bondy whose work had been banned by the government. In the following three years, Bondy's lyrics nearly completely dominated PPU's music. In December 1974, the band recorded their first \"studio\" album, \"Egon Bondy's Happy Hearts Club Banned\" (the title being a play on The Beatles' \"Sgt. Pepper's Lonely Hearts Club Band\"), which was released in France in 1978. In 1974, thousands of people traveled from Prague to the town of České Budějovice to visit the Plastics' performance. Stopped by police, they were sent back to Prague, and several students were arrested. The band was forced underground until the Velvet Revolution in 1989. Unable to perform openly, an entire underground cultural movement formed around the band during the 1970s. The sympathizers of the movement were often called \"máničky\", mainly due to their long hair. In 1976, the Plastics and other people from the underground scene were arrested and put on trial (after performing at the Third festival of the second culture) by the Communist government to make an example. They were convicted of \"organized disturbance of the peace\" and sentenced to terms in prison ranging from 8 to 18 months. Paul Wilson was deported even though he had left the band in 1972. Although the band was not associated with politics, the Communist regime's accusations against them ended up with many protests. It was partly in protest of these arrests and prosecution that playwright Václav Havel and others wrote the Charter 77. The Trial of the Plastics became a milestone for opposition against the Communist regime in Czechoslovakia for human rights. In 1978, the PPU recorded Pašijové hry velikonoční (released in Canada as \"The Passion Play\" at Paul Wilson's company Boží mlýn). The lyrics were written earlier by Vratislav Brabenec. In 1979, followed Jak bude po smrti, being influenced by a Czech philosopher and writer from the first half of the 20th century, Ladislav Klíma. In 1980, they rehearsed and performed a new record, recorded one year later, Co znamená vésti koně (released in Canada as \"Leading Horses\"). In 1982, Vratislav Brabenec was forced by the police to leave and emigrate to Canada. After he left, the band released its next record Hovězí porážka (1983) and Půlnoční myš (1986, Midnight Mouse). Czech record label Globus International has collected the original work of the Plastic People as 10 CDs, and released them in various forms several times between 1992 and 2004, with various liner notes and photos, and also as a limited edition box set. They have also released other PPU live and solo albums, and related work such as DG 307. Despite their clashes with the government, the musicians never considered themselves activists and always claimed that they wanted only to play their music. The band broke up in 1988, with some members forming the group Půlnoc (meaning \"midnight\" in Czech), which recorded briefly for Arista Records in the USA. At President Havel's suggestion, they reunited in 1997 in honor of the 20th anniversary of Charter 77, and have performed around the world regularly since then.

However an official group of artists and writers was mobilized into an \"anti-charter\" movement which included Czechoslovakia's foremost singer Karel Gott as well as prominent comedic writer Jan Werich who later claimed he had no idea of what he was doing whilst signing the anti-charter. Several means of retaliation were used against the signatories, including dismissal from work, denial of educational opportunities for their children, suspension of drivers' licenses, forced exile, loss of citizenship, and detention, trial, and imprisonment.

In triglycerides, the hydroxyl groups of the glycerol join the carboxyl groups of the fatty acid to form ester bonds: The three fatty acids (RCOH, R′COH, R′′COH in the above equation) are usually different, as many kinds of triglycerides are known. The chain lengths of the fatty acids in naturally occurring triglycerides vary, but most contain 16, 18, or 20 carbon atoms. Natural fatty acids found in plants and animals are typically composed of only even numbers of carbon atoms, reflecting the pathway for their biosynthesis from the two-carbon building-block acetyl CoA. Bacteria, however, possess the ability to synthesise odd- and branched-chain fatty acids. As a result, ruminant animal fat contains odd-numbered fatty acids, such as 15, due to the action of bacteria in the rumen.

In triglyceride form, lipids cannot be absorbed by the duodenum. Fatty acids, monoglycerides (one glycerol, one fatty acid), and some diglycerides are absorbed by the duodenum, once the triglycerides have been broken down. In the intestine, following the secretion of lipases and bile, triglycerides are split into monoacylglycerol and free fatty acids in a process called lipolysis. They are subsequently moved to absorptive enterocyte cells lining the intestines. The triglycerides are rebuilt in the enterocytes from their fragments and packaged together with cholesterol and proteins to form chylomicrons. These are excreted from the cells and collected by the lymph system and transported to the large vessels near the heart before being mixed into the blood. Various tissues can capture the chylomicrons, releasing the triglycerides to be used as a source of energy. Liver cells can synthesize and store triglycerides. When the body requires fatty acids as an energy source, the hormone glucagon signals the breakdown of the triglycerides by hormone-sensitive lipase to release free fatty acids. As the brain cannot utilize fatty acids as an energy source (unless converted to a ketone), the glycerol component of triglycerides can be converted into glucose, via gluconeogenesis by conversion into dihydroxyacetone phosphate and then into glyceraldehyde 3-phosphate, for brain fuel when it is broken down. Fat cells may also be broken down for that reason if the brain's needs ever outweigh the body's. Triglycerides cannot pass through cell membranes freely. Special enzymes on the walls of blood vessels called lipoprotein lipases must break down triglycerides into free fatty acids and glycerol. Fatty acids can then be taken up by cells via the fatty acid transporter (FAT).

He submitted darkly humorous illustrations to journals such as the anarchist satirical magazine \"L'Assiette au Beurre\", and also \"Le Rire\", \"Le Charivari\", and \"Le Cri de Paris\". In Paris, Gris followed the lead of Metzinger and another friend and fellow countryman, Pablo Picasso. Gris began to paint seriously in 1911 (when he gave up working as a satirical cartoonist), developing at this time a personal Cubist style. In \"A Life of Picasso\", John Richardson writes that Jean Metzinger's 1911 work, \"Le goûter (Tea Time)\", persuaded Juan Gris of the importance of mathematics in painting. Gris exhibited for the first time at the 1912 Salon des Indépendants (a painting entitled \"Hommage à Pablo Picasso\"). \"He appears with two styles\", writes art historian Peter Brooke, \"In one of them a grid structure appears that is clearly reminiscent of the \"Goûter\" and of Metzinger's later work in 1912.\" In the other, Brooke continues, \"the grid is still present but the lines are not stated and their continuity is broken. Their presence is suggested by the heavy, often triangular, shading of the angles between them... Both styles are distinguished from the work of Picasso and Braque by their clear, rational and measurable quality.\" Although Gris regarded Picasso as a teacher, Gertrude Stein wrote in \"The Autobiography of Alice B. Toklas\" that \"Juan Gris was the only person whom Picasso wished away\". In 1912 Gris exhibited at the \"Exposicío d'art cubista\", Galeries Dalmau in Barcelona, the first declared group exhibition of Cubism worldwide; the gallery Der Sturm in Berlin; the \"Salon de la Société Normande de Peinture Moderne\" in Rouen; and the Salon de la Section d'Or in Paris. Gris, in that same year, signed a contract that gave Daniel-Henry Kahnweiler exclusive rights to his work. At first Gris painted in the style of \"Analytical Cubism\", a term he himself later coined, but after 1913 he began his conversion to \"Synthetic Cubism\", of which he became a steadfast interpreter, with extensive use of papier collé or, collage. Unlike Picasso and Braque, whose Cubist works were practically monochromatic, Gris painted with bright harmonious colors in daring, novel combinations in the manner of his friend Matisse. Gris exhibited with the painters of the Puteaux Group in the Salon de \"la Section d'Or\" in 1912. His preference for clarity and order influenced the Purist style of Amédée Ozenfant and Charles Edouard Jeanneret (Le Corbusier), and made Gris an important exemplar of the post-war \"return to order\" movement. In 1915 he was painted by his friend, Amedeo Modigliani.

As a young boy he developed an interest in science while working for his father, who owned the local pharmacy. He and his brother Anders received most of their early education through self-study at home, going to Copenhagen in 1793 to take entrance exams for the University of Copenhagen, where both brothers excelled academically. By 1796, Ørsted had been awarded honors for his papers in both aesthetics and physics. He earned his doctorate in 1799 for a dissertation based on the works of Kant entitled \"The Architectonics of Natural Metaphysics\". In 1800, Alessandro Volta reported his invention of the voltaic pile, which inspired Ørsted to investigate the nature of electricity and to conduct his first electrical experiments. In 1801, Ørsted received a travel scholarship and public grant which enabled him to spend three years traveling across Europe. He toured science headquarters throughout the continent, including in Berlin and Paris. In Germany Ørsted met Johann Wilhelm Ritter, a physicist who believed there was a connection between electricity and magnetism. This idea made sense to Ørsted as he subscribed to Kantian thought regarding the unity of nature. Ørsted's conversations with Ritter drew him into the study of physics. He became a professor at the University of Copenhagen in 1806 and continued research on electric currents and acoustics. Under his guidance the university developed a comprehensive physics and chemistry program and established new laboratories. Ørsted welcomed William Christopher Zeise to his family home in autumn 1806. He granted Zeise a position as his lecturing assistant and took the young chemist under his tutelage. In 1812, Ørsted again visited Germany and France after publishing \"Videnskaben om Naturens Almindelige Love\" and \"Første Indledning til den Almindelige Naturlære\" (1811).

He had, in fact, been looking for a connection between electricity and magnetism since 1818, but was quite confused by the results he was obtaining. His initial interpretation was that magnetic effects radiate from all sides of a wire carrying an electric current, as do light and heat. Three months later, he began more intensive investigations and soon thereafter published his findings, showing that an electric current produces a circular magnetic field as it flows through a wire. For his discovery, the Royal Society of London awarded Ørsted the Copley Medal in 1820 and the French Academy granted him 3,000 francs. Ørsted's findings stirred much research into electrodynamics throughout the scientific community, influencing French physicist André-Marie Ampère's developments of a single mathematical formula to represent the magnetic forces between current-carrying conductors.

In 1808, Humphry Davy had predicted the existence of the metal which he gave the name of alumium. However his attempts to isolate it using electrolysis processes were unsuccessful. The closest he came was an aluminum-iron alloy. Ørsted was the first to isolate the element via a reduction of aluminium chloride. Although the aluminium alloy he extracted still contained impurities, he is credited with discovery of the metal.

In 1949 he participated with the other CoBrA artists in the Stedelijk Museum Amsterdam; this generated a huge scandal and many objections in the press and public. He was influenced by Pablo Picasso, Henri Matisse, and the French brute-art artist Jean Dubuffet. In 1947 he started sculpting with all kinds of used materials (in the technique of assemblage) and painted them in bright colors: white, red, yellow, blue, and black. He joined the Experimentele Groep in Holland together with the young Dutch painters Anton Rooskens, Theo Wolvecamp, and Jan Nieuwenhuys. Later the Belgian writer Hugo Claus joined the group. In 1948 Appel joined CoBrA (from Copenhagen, Brussels, Amsterdam) together with the Dutch artists Corneille, Constant, and Jan Nieuwenhuys (see also Aart Kemink), and with the Belgian poet Christian Dotremont. The new art of the CoBrA group was not popular in the Netherlands, but it found a warm and broad welcome in Denmark. By 1939, Danish artists had already started to make spontaneous art and one of their sources of inspiration was Danish and Nordic mythology. It was also in Denmark that the CoBrA artists started cooperating by collectively painting the insides of houses, which encouraged and intensified the exchange of the typical 'childish' and spontaneous picture language used by the CoBrA group. Appel used this very intensively; his 1949 fresco 'Questioning Children' in Amsterdam City Hall caused controversy and was covered up for ten years.

The legal rule is that unless a statute specifically prescribes a particular method of making a signature it may be made in any number of ways. These include by a mechanical or rubber stamp facsimile. A signature may be made by the purported signatory; alternatively someone else duly authorized by the signatory, acting in the signer's presence and at the signatory's direction, may make the signature. Many individuals have much more fanciful signatures than their normal cursive writing, including elaborate ascenders, descenders and exotic flourishes, much as one would find in calligraphic writing. As an example, the final \"k\" in John Hancock's famous signature on the US Declaration of Independence loops back to underline his name. This kind of flourish is also known as a \"paraph\". Paraphe is a term meaning flourish, initial or signature in French. The paraph is used in graphology analyses. Several cultures whose languages use writing systems other than alphabets do not share the Western notion of signatures per se: the \"signing\" of one's name results in a written product no different from the result of \"writing\" one's name in the standard way. For these languages, to write or to sign involves the same written characters.

In 1927, he abandoned medicine to learn traditional academic painting at the private Podolini-Volkmann Academy. In 1928/1929, he enrolled at Sándor Bortnyik's private art school called \"Műhely\" (lit. \"Workshop\", in existence until 1938), then widely recognized as Budapest's centre of Bauhaus studies. Cash-strapped, the \"műhely\" could not offer all that the Bauhaus offered. Instead it concentrated on applied graphic art and typographical design. In 1929, he painted his \"Blue Study\" and \"Green Study\". In 1930, he married his fellow student Claire Spinner (1908–1990). Together they had two sons, Andre and Jean-Pierre. Jean-Pierre was also an artist and used the professional name 'Yvaral'. In Budapest, he worked for a ball-bearings company in accounting and designing advertising posters. Vasarely became a graphic designer and a poster artist during the 1930s combining patterns and organic images with each other. Vasarely left Hungary and settled in Paris in 1930. He worked as a graphic artist and as a creative consultant at the advertising agencies Havas, Draeger, and Devambez (1930–1935). His interactions with other artists during this time were limited. He thought of opening an institution modelled after Sándor Bortnyik's \"műhely\" and developed some teaching material for it. Having lived mostly in cheap hotels, he settled in 1942/1944 in Saint-Céré in the Lot \"département\". After the Second World War, he opened an atelier in Arcueil, a suburb about 10 kilometres from the centre of Paris (in the Val-de-Marne \"département\" of the Île-de-France). In 1961, he finally settled in Annet-sur-Marne (in the Seine-et-Marne \"département\"). Vasarely eventually went on to produce art and sculpture using optical illusion. Over the next three decades, Vasarely developed his style of geometric abstract art, working in various materials but using a minimal number of forms and colours: In October 1967, designer Will Burtin invited Vasarely to make a presentation to Burtin's Vision '67 conference, held at New York University. On 5 June 1970, Vasarely opened his first dedicated museum with over 500 works in a renaissance palace in Gordes (closed in 1996). A second major undertaking was the \"Foundation Vasarely\" in Aix-en-Provence, a museum housed in a distinct structure specially designed by Vasarely. It was inaugurated in 1976 by French president Georges Pompidou, two years after his death. Sadly the museum is now in a state of disrepair, several of the pieces on display have been damaged by water leaking from the ceiling. Also, in 1976 his large kinematic object \"Georges Pompidou\" was installed in the Centre Pompidou in Paris and the Vasarely Museum located at his birthplace in Pécs, Hungary, was established with a large donation of works by Vasarely. In the same decade, he took a stab at industrial design with a 500-piece run of the upscale \"Suomi\" tableware by Timo Sarpaneva that Vasarely decorated for the German Rosenthal porcelain maker's \"Studio Linie\". In 1982, 154 specially created serigraphs were taken into space by the cosmonaut Jean-Loup Chrétien on board the French-Soviet spacecraft Salyut 7 and later sold for the benefit of UNESCO.

Mayor's doctoral thesis at the University of Geneva was devoted to the spiral structure of galaxies. During his time as a research associate, there had been strong interest in developing photoelectric-based Doppler spectrometers to obtain more accurate measurements of radial velocities of stellar objects compared to existing photographic methods. Following preliminary work by Roger Griffin in 1967 to show the feasibility of photoelectric measurements of radial velocities, Mayor worked with André Baranne at the Marseille Observatory to develop COREVAL, a photoelectric spectrometer capable of highly accurate radial velocity measurements, which allow measurement of star movements, orbital periods of binary stars, and even the rotational speed of stars. This research led to various fields of interest, including the study of statistical characteristics of solar-type binary stars. With fellow researcher Antoine Duquennoy, they examined the radial velocities of several systems believed to be binary stars in 1991. Their results found that a subset of these may in fact be single star systems with substellar secondary objects. Desiring more accurate radial velocity measurements, Mayor, along with Baranne at Marseille, and with graduate student Didier Queloz, developed ELODIE, a new spectrograph based on the work of CORAVEL, which was estimated to have an accuracy of 15 m/s for bright stars, improving upon the 1 km/s from CORAVEL. ELODIE was developed with the specific intent to determine if the substellar secondary objects were brown dwarf stars or potentially giant planets. By 1994, ELODIE was operational at Geneva and Mayor and Queloz began their survey of Sun-like systems with suspected substellar secondary objects. In July 1995, the pair's survey of the 51 Pegasi affirmed that there was an exoplanet orbiting it, identified as 51 Pegasi b which was later classified as a Hot Jupiter-type planet. This was the first exoplanet to be found orbiting a main sequence star, as opposed to planets that orbited the remains of a star. Mayor's and Queloz's discovery of an exoplanet launched great interest is searching for other exoplanets since. As of 2019, there are at least 4000 confirmed exoplanet discoveries with several more potential candidates. Mayor's work focused more on improving instrumentation for radial velocity measurements to improve detecting exoplanets and measuring their properties. Mayor led a team to further improve ELODIE to increase velocity measurement accuracy to 1 m/s via the High Accuracy Radial Velocity Planet Searcher (HARPS) installed on the ESO 3.6 m Telescope at La Silla Observatory in Chile by 2003. Mayor led the team that used HARPS to seek out other exoplanets. In 2007, Mayor was one of 11 European scientists who discovered Gliese 581c, the first extrasolar planet in a star's habitable zone, from the ESO telescope. In 2009, Mayor and his team discovered the lightest exoplanet ever detected around a main sequence star: Gliese 581e. Nonetheless, Mayor noted that humans will never migrate to such exoplanets since they are \"much, much too far away...

Henry's mother was Gertrude, only daughter of the Emperor Lothair III and his wife Richenza of Northeim, heiress of the Saxon territories of Northeim and the properties of the Brunones, counts of Brunswick. Henry's father died in 1139, aged 32, when Henry was still a child. King Conrad III had dispossessed Henry the Proud of his duchies in 1138 and 1139, handing Saxony to Albert the Bear and Bavaria to Leopold of Austria. This was because Henry the Proud had been his rival for the Crown in 1138. Henry III, however, did not relinquish his claims to his inheritance, and Conrad returned Saxony to him in 1142. A participant in the 1147 Wendish Crusade, Henry also reacquired Bavaria by a decision of the new Emperor Frederick Barbarossa in 1156. However, the East Mark was not returned, which became Austria. Henry was the founder of Munich (1157; \"München\") and Lübeck (1159); he also founded and developed numerous other cities in Northern Germany and Bavaria, a.o. Augsburg, Hildesheim, Stade, Kassel, Güstrow, Lüneburg, Salzwedel, Schwerin and Brunswick. In Brunswick, his capital, he had a bronze lion, his heraldic animal, erected in the courtyard of his castle Dankwarderode in 1166 — the first bronze statue north of the Alps. Later, he had Brunswick Cathedral built close to the statue. In 1147, Henry married Clementia of Zähringen, thereby gaining her hereditary territories in Swabia. He divorced her in 1162, apparently under pressure from the Emperor Frederick Barbarossa, who did not cherish Guelphish possessions in his home area and offered Henry several fortresses in Saxony in exchange. In 1168, Henry married Matilda (1156–1189), the daughter of King Henry II of England and Duchess Eleanor of Aquitaine and sister of King Richard I of England. Henry faithfully supported his older cousin, the Emperor Frederick I (Barbarossa), in his attempts to solidify his hold on the Imperial Crown and his repeated wars with the cities of Lombardy and the Popes, several times turning the tide of battle in Frederick's favor with his Saxon knights. During Frederick's first invasion of northern Italy, Henry took part, among the others, in the victorious sieges of Crema and Milan. In 1172, Henry took a pilgrimage to Jerusalem (June–July), meeting with the Knights Templar and Knights Hospitaller, and spending Easter of that year in Constantinople. By December 1172, he was back in Bavaria and in 1174, he refused to aid Frederick in a renewed invasion of Lombardy because he was preoccupied with securing his own borders in the East. He did not consider these Italian adventures worth the effort, unless Barbarossa presented Henry with the Saxon imperial city Goslar: a request Barbarossa refused. Barbarossa's expedition into Lombardy ultimately ended in failure. He bitterly resented Henry for failing to support him. Taking advantage of the hostility of other German princes to Henry, who had successfully established a powerful and contiguous state comprising Saxony, Bavaria and substantial territories in the north and east of Germany, Frederick had Henry tried \"in absentia\" for insubordination by a court of bishops and princes in 1180. Declaring that Imperial law overruled traditional German law, the court had Henry stripped of his lands and declared him an outlaw. Frederick then invaded Saxony with an Imperial army to bring his cousin to his knees. Henry's allies deserted him, and he finally had to submit in November 1181 at an Imperial Diet in Erfurt. He was exiled from Germany in 1182 for three years, and stayed with his father-in-law in Normandy before being allowed back into Germany in 1185. At Whitsun 1184 he visited the Diet of Pentecost in Mainz, probably as a mediator for his father-in-law Heinrich II. He was exiled again in 1188. His wife Matilda died in 1189. When Frederick Barbarossa went on the Crusade of 1189, Henry returned to Saxony, mobilized an army of his faithful, and conquered the rich city of Bardowick as punishment for its disloyalty. Only the churches were left standing.

This works for any polygon, regular or non-regular, and any location of the apex, provided that \"h\" is measured as the perpendicular distance from the plane containing the base. In 499 AD Aryabhata, a mathematician-astronomer from the classical age of Indian mathematics and Indian astronomy, used this method in the \"Aryabhatiya\" (section 2.6). The formula can be formally proved using calculus. By similarity, the \"linear\" dimensions of a cross-section parallel to the base increase linearly from the apex to the base. The scaling factor (proportionality factor) is formula_2, or formula_3, where \"h\" is the height and \"y\" is the perpendicular distance from the plane of the base to the cross-section. Since the area of any cross-section is proportional to the square of the shape's scaling factor, the area of a cross-section at height \"y\" is formula_4, or since both \"b\" and \"h\" are constants, formula_5. The volume is given by the integral The same equation, formula_1, also holds for cones with any base. This can be proven by an argument similar to the one above; see volume of a cone. For example, the volume of a pyramid whose base is an \"n\"-sided regular polygon with side length \"s\" and whose height is \"h\" is The formula can also be derived exactly without calculus for pyramids with rectangular bases. Consider a unit cube. Draw lines from the center of the cube to each of the 8 vertices. This partitions the cube into 6 equal square pyramids of base area 1 and height 1/2. Each pyramid clearly has volume of 1/6. From this we deduce that pyramid volume = height × base area / 3. Next, expand the cube uniformly in three directions by unequal amounts so that the resulting rectangular solid edges are \"a\", \"b\" and \"c\", with solid volume \"abc\". Each of the 6 pyramids within are likewise expanded. And each pyramid has the same volume \"abc\"/6. Since pairs of pyramids have heights \"a\"/2, \"b\"/2 and \"c\"/2, we see that pyramid volume = height × base area / 3 again. When the side triangles are equilateral, the formula for the volume is This formula only applies for \"n\" = 2, 3, 4 and 5; and it also covers the case \"n\" = 6, for which the volume equals zero (i.e., the pyramid height is zero).", "section_level": 1}, {"title": "Surface area.", "content": "The surface area of a pyramid is formula_10, where \"B\" is the base area, \"P\" is the base perimeter, and the slant height formula_11, where \"h\" is the pyramid altitude and \"r\" is the inradius of the base.", "section_level": 1}, {"title": "Centroid.", "content": "The centroid of a pyramid is located on the line segment that connects the apex to the centroid of the base.

Also during his travels in Russia his son Nikolaus was born on 20 August 1906, starting a two-year fight with the mother, Rosa Schwab, for the custody of the child, which Barlach was finally granted. After returning from Russia, Barlach's financial situation improved considerably, as he received a fixed salary from the art dealer Paul Cassirer in exchange for his sculptures. The formative experiences in Russia and the financial security helped him to develop his own style, focusing on the faces and hands of the people in his sculptures and reducing the other parts of the figures to a minimum. He also began to make wood carvings and bronzes of figures swathed in heavy drapery like those in early Gothic art, and in dramatic attitudes expressive of powerful emotions and a yearning for spiritual ecstasy. He also worked for the German journal \"Simplicissimus\", and started to produce some literature. His works were shown on various exhibitions. He also spent ten months in Florence, Italy in 1909 and afterwards settled in 1910 in Güstrow in Mecklenburg, where he spent the rest of his life. In the years before World War I, Barlach was a patriotic and enthusiastic supporter of the war, awaiting a new artistic age from the war. This support for the war can also be seen in his works, as for example the statue \"Der Rächer\" (The Avenger), from December 1914. His awaited \"new artistic age\" came for him when he volunteered to join the war between 1915 and 1916 as an infantry soldier.

This pacifist position went against the political trend during the rise of Nazism, and he was the target of much criticism. For example, the \"Magdeburger Ehrenmal\" (Magdeburg cenotaph) was ordered by the city of Magdeburg to be a memorial of World War I, and it was expected to show heroic German soldiers fighting for their glorious country. Barlach, however, created a sculpture with three German soldiers, a fresh recruit, a young officer and an old reservist, standing in a cemetery, all bearing marks of the horror, pain and desperation of the war, flanked by a mourning war widow covering her face in despair, a skeleton wearing a German army helmet, and a civilian (the face is that of Barlach himself) with his eyes closed and blocking his ears in terror. This naturally created a controversy with the pro-war population (several nationalists and Nazis claimed that the soldiers must be foreign since true Germans would be more heroic), and the sculpture was removed. Friends of Barlach were able to hide the sculpture until after the war, when it was returned to the Magdeburg Cathedral. Yet the attacks on Barlach continued until his death. In 1931 Barlach started to live with Marga Böhmer, whereas her ex-husband and Barlach's friend Bernhard Böhmer lived with his new wife Hella. In 1936, Barlach's works were confiscated during an exhibition together with the works of Käthe Kollwitz and Wilhelm Lehmbruck, and the majority of his remaining works were confiscated as \"degenerate art\", for example the \"Güstrower Ehrenmal\" (Güstrow cenotaph) and the \"Hamburger Ehrenmal\" (Hamburg cenotaph). Barlach himself was prohibited from working as a sculptor, and his membership in the art academies was canceled. This rejection is reflected in his final works before his death from heart failure on 24 October 1938 in Rostock, Mecklenburg. He is buried in the cemetery of Ratzeburg.

During this period, exponents of land art rejected the museum or gallery as the setting of artistic activity and developed monumental landscape projects which were beyond the reach of traditional transportable sculpture and the commercial art market, although photographic documentation was often presented in normal gallery spaces. Land art was inspired by minimal art and conceptual art but also by modern movements such as De Stijl, Cubism, minimalism and the work of Constantin Brâncuși and Joseph Beuys. Many of the artists associated with land art had been involved with minimal art and conceptual art. Isamu Noguchi's 1941 design for \"Contoured Playground\" in New York is sometimes interpreted as an important early piece of land art even though the artist himself never called his work \"land art\" but simply \"sculpture\". His influence on contemporary land art, landscape architecture and environmental sculpture is evident in many works today. Alan Sonfist used an alternative approach to working with nature and culture by bringing historical nature and sustainable art back into New York City. His most inspirational work is \"Time Landscape\", an indigenous forest he planted in New York City. He also created several other \"Time Landscapes\" around the world such as \"Circles of Time\" in Florence Italy documenting the historical usage of the land, and recently at the deCordova Sculpture Park and Museum outside Boston. According to critic Barbara Rose, writing in \"Artforum\" in 1969, he had become disillusioned with the commodification and insularity of gallery bound art. In 1967, the art critic Grace Glueck writing in the \"New York Times\" declared the first earthwork was done by Douglas Leichter and Richard Saba at the Skowhegan School of Painting and Sculpture. The sudden appearance of land art in 1968 can be located as a response by a generation of artists mostly in their late twenties to the heightened political activism of the year and the emerging environmental and women's liberation movements. One example of land art in the 20th century was a group exhibition created in 1968 at the Dwan Gallery in New York. In February 1969, Willoughby Sharp curated the \"Earth Art\" exhibition at the Andrew Dickson White Museum of Art at Cornell University, Ithaca, New York. The artists included were Walter De Maria, Jan Dibbets, Hans Haacke, Michael Heizer, Neil Jenney, Richard Long, David Medalla, Robert Morris, Dennis Oppenheim, Robert Smithson, and Gunther Uecker. The exhibition was directed by Thomas W. Leavitt. Gordon Matta-Clark, who lived in Ithaca at the time, was invited by Sharp to help the artists in \"Earth Art\" with the on-site execution of their works for the exhibition. Perhaps the best known artist who worked in this genre was the American Robert Smithson whose 1968 essay \"The Sedimentation of the Mind: Earth Projects\" provided a critical framework for the movement as a reaction to the disengagement of Modernism from social issues as represented by the critic Clement Greenberg. His best known piece, and probably the most famous piece of all land art, is the \"Spiral Jetty\" (1970), for which Smithson arranged rock, earth and algae so as to form a long (1500 ft) spiral-shape jetty protruding into Great Salt Lake in northern Utah, U.S.. How much of the work, if any, is visible is dependent on the fluctuating water levels. Since its creation, the work has been completely covered, and then uncovered again, by water. A steward of the artwork in conjunction with the Dia Foundation, the Utah Museum of Fine Arts regularly curates programming around the Spiral Jetty, including a \"Family Backpacks\" program. Smithson's \"Gravel Mirror with Cracks and Dust\" (1968) is an example of land art existing in a gallery space rather than in the natural environment. It consists of a pile of gravel by the side of a partially mirrored gallery wall. In its simplicity of form and concentration on the materials themselves, this and other pieces of land art have an affinity with minimalism. There is also a relationship to Arte Povera in the use of materials traditionally considered \"unartistic\" or \"worthless\". The Italian Germano Celant, founder of Arte Povera, was one of the first curator to promote Land Art. 'Land Artists' have tended to be American, with other prominent artists in this field including, Carl Andre, Alice Aycock, Walter De Maria, Hans Haacke, Michael Heizer, Nancy Holt, Ana Mendieta, Dennis Oppenheim, Andrew Rogers, Charles Ross, Alan Sonfist, and James Turrell. Turrell began work in 1972 on possibly the largest piece of land art thus far, reshaping the earth surrounding the extinct Roden Crater volcano in Arizona. Perhaps the most prominent non-American land artists are the British Chris Drury, Andy Goldsworthy, Richard Long and the Australian Andrew Rogers. In 1973 Jacek Tylicki begins to lay out blank canvases or paper sheets in the natural environment for the nature to create art. Some projects by the artists Christo and Jeanne-Claude (who are famous for wrapping monuments, buildings and landscapes in fabric) have also been considered land art by some, though the artists themselves consider this incorrect. Joseph Beuys' concept of'social sculpture' influenced 'Land art' and his '7000 Eichen' project of 1982 to plant 7000 Oak trees has many similarities to 'Land art' processes. Rogers' “Rhythms of Life” project is the largest contemporary land-art undertaking in the world, forming a chain of stone sculptures, or geoglyphs, around the globe – 12 sites – in disparate exotic locations (from below sea level and up to altitudes of 4,300 m/14,107 ft). Up to three geoglyphs (ranging in size up to 40,000 sq m/430,560 sq ft) are located in each site. Land artists in America relied mostly on wealthy patrons and private foundations to fund their often costly projects. With the sudden economic down turn of the mid-1970s funds from these sources largely stopped. With the death of Robert Smithson in a plane crash in 1973 the movement lost one of its most important figureheads and faded out. Charles Ross continues to work on the Star Axis project, which he began in 1971. Michael Heizer continues his work on City, and James Turrell continues to work on the Roden Crater project. In most respects, \"land art\" has become part of mainstream public art and in many cases the term \"land art\" is misused to label any kind of art in nature even though conceptually not related to the avant-garde works by the pioneers of land art.

It is not clear when Zerbst was founded; however, the name \"Ciervisti\" mentioned as early as 949 may already refer to a fortified Slavic settlement. The chronicles by Prince-Bishop Thietmar of Merseburg recorded the first mention of a town as \"Zirwisti urbs\" in 1018, giving an account of the occupation by the Polish duke Bolesław I Chrobry during the German–Polish War with King Henry II in 1007. In the early 12th century the Ascanian ruler Albert the Bear had the fortress rebuilt, and the adjacent settlement was first fortified with town walls about 1250. In 1307 Prince Albert I of Anhalt acquired the city of Zerbst from the Barby comital family, starting a centuries-long rule by the Ascanian princely House of Anhalt. His descendants continued to rule the Principality of Anhalt-Zerbst until in 1396 it was divided between Prince Sigismund I and his brother Albert IV, and the residence was moved to Dessau. In 1375 Zerbster Bitterbier was first mentioned; by the Middle Ages the town had 600 breweries. Following the Reformation Zerbst became a Calvinist centre. From 1582 to 1798 the \"Francisceum Gymnasium Illustre\" was an important Calvinist college. From 1603 to 1793 Zerbst again was the residence of the Anhalt-Zerbst princes, whose rule included among others also the Lordship of Jever in East Frisia. From 1722 to 1758, the Baroque composer Johann Friedrich Fasch resided there and was employed as a \"Hofkomponist\" and later \"Hofkapellmeister\". To honour his memory, the Fasch Festivals have taken place in the city since 1983.

By altering the release of neurotransmitters, the plasticity of synapses can be controlled in the presynaptic cell. The postsynaptic cell can be regulated by altering the function and number of its receptors. Changes in postsynaptic signaling are most commonly associated with a N-methyl-d-aspartic acid receptor (NMDAR)-dependent long-term potentiation (LTP) and long-term depression (LTD) due to the influx of calcium into the post-synaptic cell, which are the most analyzed forms of plasticity at excitatory synapses.", "section_level": 1}, {"title": "Study models.", "content": "For technical reasons, synaptic structure and function have been historically studied at unusually large model synapses, for example:", "section_level": 1}, {"title": "Synaptic polarization.", "content": "The function of neurons depends upon cell polarity.

PIP2 signaling regulated by IMPase plays an integral role in synaptic polarity. Phosphoinositides (PIP, PIP2, and PIP3) are molecules that have been shown to affect neuronal polarity. A gene (\"ttx-7\") was identified in \"Caenorhabditis elegans\" that encodes \"myo\"-inositol monophosphatase (IMPase), an enzyme that produces inositol by dephosphorylating inositol phosphate. Organisms with mutant \"ttx-7\" genes demonstrated behavioral and localization defects, which were rescued by expression of IMPase. This led to the conclusion that IMPase is required for the correct localization of synaptic protein components. The \"egl-8\" gene encodes a homolog of phospholipase Cβ (PLCβ), an enzyme that cleaves PIP2.

One arm is wrapped behind the mare's rear leg and the other in front. A foal starts the milk flow and is pulled away by another person, but left touching the mare's side during the entire process.

During one season, a mare produces approximately 1,000 to 1,200 litres of milk, of which about half is left to the foals.", "section_level": 1}, {"title": "Production of kumis.", "content": "\"Kumis\" is made by fermenting raw unpasteurized mare's milk over the course of hours or days, often while stirring or churning. (The physical agitation has similarities to making butter). During the fermentation, lactobacilli bacteria acidify the milk, and yeasts turn it into a carbonated and mildly alcoholic drink. Traditionally, this fermentation took place in horse-hide containers, which might be left on the top of a \"yurt\" and turned over on occasion, or strapped to a saddle and joggled around over the course of a day's riding. Today, a wooden vat or plastic barrel may be used in place of the leather container. In modern controlled production, the initial fermentation takes two to five hours at a temperature of around ; this may be followed by a cooler aging period. The finished product contains between 0.7 and 2.5% alcohol. \"Kumis\" itself has a very low level of alcohol, comparable to small beer, the common drink of medieval Europe that also helps to avoid the consumption of potentially contaminated water. \"Kumis\" can, however, be strengthened through freeze distillation, a technique Central Asian nomads are reported to have employed. It can also be made into the distilled beverage known as \"araka\" or \"arkhi\".", "section_level": 1}, {"title": "History.", "content": "Archaeological investigations of the Botai culture of ancient Kazakhstan have revealed traces of milk in bowls from the site of Botai, suggesting the domestication of the animal. No specific evidence for its fermentation has yet been found, but considering the location of the Botai culture and the nutritional properties of mare's milk, the possibility is high. \"Kumis\" is an ancient beverage. Herodotus, in his 5th-century BC \"Histories\", describes the Scythians processing of mare's milk: Now the Scythians blind all their slaves, to use them in preparing their milk. The plan they follow is to thrust tubes made of bone, not unlike our musical pipes, up the vulva of the mare, and then to blow into the tubes with their mouths, some milking while the others blow. They say that they do this because when the veins of the animal are full of air, the udder is forced down. The milk thus obtained is poured into deep wooden casks, about which the blind slaves are placed, and then the milk is stirred round. That which rises to the top is drawn off, and considered the best part; the under portion is of less account. This is widely believed to be the first description of ancient kumis-making. Apart from the idiosyncratic method of mare-milking, it matches up well enough with later accounts, such as this one given by 13th-century traveller William of Rubruck: This \"cosmos\", which is mare's milk, is made in this wise. [...] When they have got together a great quantity of milk, which is as sweet as cow's as long as it is fresh, they pour it into a big skin or bottle, and they set to churning it with a stick [...] and when they have beaten it sharply it begins to boil up like new wine and to sour or ferment, and they continue to churn it until they have extracted the butter. Then they taste it, and when it is mildly pungent, they drink it. It is pungent on the tongue like rapé wine when drunk, and when a man has finished drinking, it leaves a taste of milk of almonds on the tongue, and it makes the inner man most joyful and also intoxicates weak heads, and greatly provokes urine.

But in terms of experience and traditional manner of consumption, it is much more comparable to beer. It is even milder in alcoholic content than beer. It is arguably the region’s beer equivalent. \"Kumis\" is very light in body compared to most dairy drinks. It has a unique, slightly sour flavor with a bite from the mild alcoholic content. The exact flavor is greatly variable between different producers. \"Kumis\" is usually served cold or chilled. Traditionally it is sipped out of small, handle-less, bowl-shaped cups or saucers, called \"piyala\".

In 1599 she moved to the house of Sir Ralph Babthorpe at Osgodby, Selby. It was there at the age of 15 that Mary felt called to the religious life. She entered a monastery of Poor Clares at Saint-Omer in northern France, then in the Spanish Netherlands, as a lay sister. In 1606 she founded a new monastery of the Order specifically for English women at nearby Gravelines.", "section_level": 1}, {"title": "Establishment of the institute.", "content": "However, Mary Ward did not find herself called to the contemplative life and instead decided to dedicate herself to an active ministry, whilst still being a religious; this was considered most unusual at the time. At the age of twenty-four she found herself surrounded by a band of devoted companions determined to work under her guidance. In 1609 they established themselves as a religious community at Saint-Omer and opened schools for girls. Although the venture was a great success, it was still controversial at the time, and it called forth censure and opposition as well as praise. Her idea was to enable women to do for the Church in their proper field, what men had done for it in the Society of Jesus. The idea has been realized over and over again in modern times, but in the 17th century it met with little encouragement. As previous foundresses who attempted such a way of life (e.g., St. Angela Merici) had learned, uncloistered religious sisters were repugnant to long-standing principles and traditions then prevalent. At that time, the work of religious women was confined to what could be carried on within the walls of a monastery, either teaching boarding students within the cloister or nursing the sick in hospitals attached to the monastery. There were other new startling differences between the new Institute and existing congregations of women, freedom from: enclosure, the obligation of choir, wearing a religious habit, and from the jurisdiction of the local bishop. Moreover, her scheme was proposed at a time when there was division amongst English Catholics, and the fact that it borrowed so much from the Society of Jesus (itself an object of suspicion and hostility in many quarters) increased the mistrust. Measures recognized as acceptable in modern times were still novelties in hers, and her opponents called for a statement to be made by Church authorities. As early as 1615, the Jesuit theologians Francisco Suárez and Leonardus Lessius had been asked for their opinion on the new institute; both praised its way of life. Lessius held that local episcopal authorization sufficed to render it a religious body whereas Suárez maintained that its aim, organization, and methods being without precedent in the case of women, required the sanction of the Holy See. Pope Pius V (1566–1572) had declared solemn vows and strict papal enclosure to be essential to all communities of religious women. The difficulties which Ward encountered were mainly due to this ruling, when on the propagation of her institute in Flanders, Bavaria, Austria, and Italy, she applied to the Holy See for formal approbation. The Archduchess Isabella Clara Eugenia, the Elector Maximilian I, and the Emperor Ferdinand II had welcomed the congregation to their dominions, and together with such men as Cardinal Federico Borromeo, Fra Domenico de Gesù (Domenico Ruzola), and Father Mutio Vitelleschi, Superior General of the Society of Jesus, held the foundress in great esteem. Popes Paul V, Gregory XV and Urban VIII had shown her great kindness and spoken in praise of her work, and in 1629 she was allowed to plead her cause in person before the congregation of cardinals appointed by Urban to examine the situation. The \"Jesuitesses\", as her congregation was designated by her opponents, were suppressed in 1631. Her work however was not destroyed. It revived gradually and developed, following the general lines of the first scheme. The second institute was at length approved as to its Rule by Pope Clement XI in 1703, and as an institute by Pope Pius IX in 1877. At the express desire of Pope Urban, Mary went to Rome. It was there that she gathered around her the younger members of her religious family, under the supervision and protection of the Holy See. She traveled throughout Europe on foot, in extreme poverty and frequently ill, founding schools in the Netherlands, Italy, Germany, Austria, and in today's Czech Republic and Slovakia. In 1637, with letters of introduction from Pope Urban to Queen Henrietta Maria of France, Mary returned to England and established herself in London. There she and her companions established free schools for the poor, nursed the sick and visited prisoners. In 1642 she journeyed northward with her household and established a convent at Heworth, near York. She died at St. Mary's school in the siege of York during the English Civil War. After her death there, her companions thought it best not to bury her body near the city center where she died because of the dangers of desecration. Instead they sought a less conspicuous place and found a happy solution by arranging for her to be buried in the Osbaldwick Churchyard, about a mile away. There, as the record says, \"the vicar was honest enough to be bribed\"! Her burial on 1 February 1645 was also attended by Anglicans, she was much admired and revered by many local people, both Catholic and Protestant.

On 8 August 1786, Jacques Balmat and Michel-Gabriel Paccard made the first ascent of Mont Blanc. Balmat, a chamois hunter and crystal collector, had experience with high mountain travel, and Paccard had made previous attempts to climb the peak. Illustrations show Balmat carrying two separate tools that would later be merged into the ice axe – an alpenstock (or baton) and a small axe that could be used to chop steps on icy slopes. According to the earliest manufacturer of ice axes, Grivel, these two tools were merged to create the first true ice axe around 1840. Early ice axes had a vertical adze, with the cutting edge aligned with the direction of the shaft, as in a conventional axe. This design lasted until at least 1860, but eventually the adze was rotated to the current position, perpendicular to the direction of the shaft. The Italian Alpine Club published a book in 1889 entitled \"Fiorio e Ratti – The dangers of mountaineering and rules to avoid them\", which recommended ice axes as among \"the inseparable companions of the mountaineer\". In the late 19th century, the typical ice axe shaft measured in length. British climber Oscar Eckenstein started the trend toward shorter ice axes with a lighter model measuring. Initially, this innovation was criticized by well-known climbers of the era, including Martin Conway, a prominent member of the Alpine Club, who was the leader of an early expedition to the Baltoro region near K2 in 1892 of which Eckenstein was a member. Early ice axes had picks and adzes of about equal lengths. By the beginning of the 20th century, the pick lengthened to about twice the length of the adze. Improvements in crampon design (pioneered by Eckenstein in 1908) and ice climbing technique led to use of shorter, lighter ice axes appropriate to steeper ice climbs in the period between the world wars. A famous rescue involving an ice axe took place during the Third American Karakoram Expedition to K2 in 1953. One of the climbers, Art Gilkey, was incapacitated by thrombophlebitis. The other climbers attempted to rescue him by lowering him down the mountain by rope, wrapped in a sleeping bag. While crossing a steep ice sheet, a slip caused Gilkey and five other climbers to begin falling down a steep slope. Climber Pete Schoening wedged his ice axe alongside a boulder, and managed to belay the roped climbers, saving their lives. (Gilkey, however, later in the same descent was swept away by an avalanche. Remains of his lost corpse were discovered in 1993.) Schoening's ice axe is now on display at the Bradford Washburn American Mountaineering Museum in Golden, Colorado. In 1966, Yvon Chouinard led a significant redesign of ice axes, working with initially reluctant manufacturer Charlet to develop a ice axe with a dramatically curved pick. Chouinard believed that \"a curve compatible with the arc of the axe's swing would allow the pick to stay put better in the ice. I had noticed that a standard pick would often pop out when I placed my weight on it.\" Chouinard's idea worked and began a period of innovation in ice axe design. In 1978, the Safety Commission of the Union Internationale des Associations d'Alpinisme (UIAA) established formal standards for ice axe safety and performance.

Rucksacks with attachment points for two ice axes are also available, and these are popular for use with ice tools. To use these attachment points drop the shaft of the ice axe down through the loop, then bring the end of the axe up (in an arc) to the strap/bungee, thus wrapping the head in the loop. In this way the axe cannot slide down and out of the attachment. Shorter ice axes or ice tools are sometimes slid down through the compression straps on the sides of a rucksack, but this can present some danger to others nearby as the sharp points of the picks are at eye level. For short passages where the hands are needed and/or the ice axe is not required a common and convenient, easily accessible, stowage is to slide the axe down between the back and the rucksack, between the shoulder blades.

Augustine of Hippo echoes Cicero's formulation when he declares, \"\"religion\" is nothing other than the \"cultus\" of God.\" The term \"cult\" first appeared in English in 1617, derived from the French \"culte\", meaning \"worship\" which in turn originated from the Latin word \"cultus\" meaning \"care, cultivation, worship\".

Redon's father made his fortune in the slave trade in Louisiana in the 1830s. Redon was conceived in New Orleans and the couple made the transatlantic journey back to France while his mother Marie Guérin, a French Creole woman, was pregnant. The young Bertrand Redon acquired the nickname \"Odilon\" from his mother, Odile. Redon started drawing as a child; at the age of ten, he was awarded a drawing prize at school. He began the formal study of drawing at fifteen but, at his father's insistence, he changed to architecture. Failure to pass the entrance exams at Paris’ École des Beaux-Arts ended any plans for a career as an architect, although he briefly studied painting there under Jean-Léon Gérôme in 1864. (His younger brother Gaston Redon would become a noted architect.) Back in his native Bordeaux, he took up sculpting, and Rodolphe Bresdin instructed him in etching and lithography. His artistic career was interrupted in 1870 when he was drafted to serve in the army in the Franco-Prussian War until its end in 1871. At the end of the war, he moved to Paris and resumed working almost exclusively in charcoal and lithography. He called his visionary works, conceived in shades of black, his \"noirs\". It was not until 1878 that his work gained any recognition with \"Guardian Spirit of the Waters\"; he published his first album of lithographs, titled \"Dans le Rêve\", in 1879. Still, Redon remained relatively unknown until the appearance in 1884 of a cult novel by Joris-Karl Huysmans titled \"À rebours (Against Nature)\". The story featured a decadent aristocrat who collected Redon's drawings. In the 1890s pastel and oils became his favored media; he produced no more \"noirs\" after 1900. In 1899, he exhibited with the Nabis at Durand-Ruel's. Redon had a keen interest in Hindu and Buddhist religion and culture. The figure of the Buddha increasingly showed in his work. Influences of Japonism blended into his art, such as the painting \"The Death of the Buddha\" around 1899, \"The Buddha\" in 1906, \"Jacob and the Angel\" in 1905, and \"Vase with Japanese warrior\" in 1905, amongst many others. Baron Robert de Domecy (1867–1946) commissioned the artist in 1899 to create 17 decorative panels for the dining room of the Château de Domecy-sur-le-Vault near Sermizelles in Burgundy. Redon had created large decorative works for private residences in the past, but his compositions for the château de Domecy in 1900–1901 were his most radical compositions to that point and mark the transition from ornamental to abstract painting. The landscape details do not show a specific place or space. Only details of trees, twigs with leaves, and budding flowers in an endless horizon can be seen. The colours used are mostly yellow, grey, brown and light blue. The influence of the Japanese painting style found on folding screens \"byōbu\" is discernible in his choice of colours and the rectangular proportions of most of the up to 2.5 metres high panels. Fifteen of them are located today in the Musée d'Orsay, acquisitioned in 1988. Domecy also commissioned Redon to paint portraits of his wife and their daughter Jeanne, two of which are in the collections of the Musée d'Orsay and the Getty Museum in California. Most of the paintings remained in the Domecy family collection until the 1960s. In 1903 Redon was awarded the Legion of Honor. His popularity increased when a catalogue of etchings and lithographs was published by André Mellerio in 1913; that same year, he was given the largest single representation at the groundbreaking U.S. International Exhibition of Modern Art (aka Armory Show), in New York City, Chicago and Boston.

His father Adolf was an archaeologist, his mother a painter. Most of his childhood was spent in Munich, where his father taught at the city's Ludwig Maximilian University. He was given a musical education from an early age, and developed an early love of Ludwig van Beethoven, a composer with whose works he remained closely associated throughout his life. Although Furtwängler achieved fame chiefly from his conducting, he regarded himself foremost as a composer. He began conducting in order to perform his own works. By age of twenty, he had composed several works. However, they were not well received, and that, combined with the financial insecurity of a career as a composer, led him to concentrate on conducting. He made his conducting debut with the Kaim Orchestra (now the Munich Philharmonic) in Anton Bruckner's Ninth Symphony. He subsequently held conducting posts at Munich, Strasbourg, Lübeck, Mannheim, Frankfurt, and Vienna. Furtwangler succeeded Artur Bodanzky as principal conductor of the Mannheim Opera and Music Academy in 1915, remaining until 1920. As a boy he had sometimes stayed with his grandmother in Mannheim. Through her family he met the Geissmars, a Jewish family who were leading lawyers and amateur musicians in the town. Berta Geissmar wrote, \"Furtwängler became so good at [skiing] as to attain almost professional skill...Almost every sport appealed to him: he loved tennis, sailing and swimming...He was a good horseman...\" She also reports that he was a strong mountain climber and hiker. Berta Geissmar subsequently became his secretary and business manager, in Mannheim and later in Berlin, until she was forced to leave Germany in 1934. From 1921 onwards, Furtwängler shared holidays in the Engadin with Berta and her mother. In 1924 he bought a house there. After he married, the house was open to a wide circle of friends. In 1920 he was appointed conductor of the Berlin Staatskapelle succeeding Richard Strauss. In January 1922, following the sudden death of Arthur Nikisch, he was appointed to the Leipzig Gewandhaus Orchestra. Shortly afterwards he was appointed to the prestigious Berlin Philharmonic Orchestra, again in succession to Nikisch. Furtwängler made his London debut in 1924, and continued to appear there before the outbreak of World War II as late as 1938, when he conducted Richard Wagner's \"Ring\". (Furtwängler later conducted in London many times between 1948 and 1954). In 1925 he appeared as guest conductor of the New York Philharmonic Orchestra, making return visits in the following two years. In January 1945 Furtwängler fled to Switzerland. It was during this period that he completed what is considered his most significant composition, the Symphony No. 2 in E minor. It was given its premiere in 1948 by the Berlin Philharmonic Orchestra under Furtwängler's direction and was recorded for Deutsche Grammophon. Following the war, he resumed performing and recording, and remained a popular conductor in Europe, although his actions in the 1930s and 40s were a subject of ongoing criticism.

Furtwängler had this very rare and great gift of going beyond the printed score and showing what music really was. Many commentators and critics regard him as the greatest conductor in history. In his book on the symphonies of Johannes Brahms, musicologist Walter Frisch writes that Furtwängler's recordings show him to be \"the finest Brahms conductor of his generation, perhaps of all time\", demonstrating \"at once a greater attention to detail and to Brahms' markings than his contemporaries and at the same time a larger sense of rhythmic-temporal flow that is never deflected by the individual nuances.

Bile salt anions are hydrophilic on one side and hydrophobic on the other side; consequently, they tend to aggregate around droplets of lipids (triglycerides and phospholipids) to form micelles, with the hydrophobic sides towards the fat and hydrophilic sides facing outwards. The hydrophilic sides are negatively charged, and this charge prevents fat droplets coated with bile from re-aggregating into larger fat particles. Ordinarily, the micelles in the duodenum have a diameter around 1–50 μm in humans. The dispersion of food fat into micelles provides a greatly increased surface area for the action of the enzyme pancreatic lipase, which actually digests the triglycerides, and is able to reach the fatty core through gaps between the bile salts. A triglyceride is broken down into two fatty acids and a monoglyceride, which are absorbed by the villi on the intestine walls. After being transferred across the intestinal membrane, the fatty acids reform into triglycerides (re-esterified), before being absorbed into the lymphatic system through lacteals. Without bile salts, most of the lipids in food would be excreted in feces, undigested. Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances, such as the vitamins A, D, E, and K. Besides its digestive function, bile serves also as the route of excretion for bilirubin, a byproduct of red blood cells recycled by the liver. Bilirubin derives from hemoglobin by glucuronidation. Bile tends to be alkali on average. The pH of common duct bile (7.50 to 8.05) is higher than that of the corresponding gallbladder bile (6.80 to 7.65). Bile in the gallbladder becomes more acidic the longer a person goes without eating, though resting slows this fall in pH.

In addition, past the small intestine (which is normally responsible for absorbing fat from food) the gastrointestinal tract and gut flora are not adapted to processing fats, leading to problems in the large intestine. The cholesterol contained in bile will occasionally accrete into lumps in the gallbladder, forming gallstones. Cholesterol gallstones are generally treated through surgical removal of the gallbladder. However, they can sometimes be dissolved by increasing the concentration of certain naturally occurring bile acids, such as chenodeoxycholic acid and ursodeoxycholic acid.

After her mother's death, Sachs suffered several nervous breakdowns characterized by hallucinations, paranoia, and delusions of persecution by Nazis, and spent a number of years in a mental institution. She continued to write while hospitalized, and eventually recovered sufficiently to live on her own, though her mental health remained fragile. Her worst breakdown was ostensibly precipitated by hearing spoken German during a trip to Switzerland to accept a literary prize. But she maintained a forgiving attitude toward younger Germans, and corresponded with many German-speaking writers of the postwar period, including Hans Magnus Enzensberger and Ingeborg Bachmann. On the 127th anniversary of her birthday, 10 December 2018, Sachs was commemorated with a Google Doodle in parts of Europe and the US.", "section_level": 1}, {"title": "Paul Celan and lyrical poetry.", "content": "In the context of the Shoah, her deep friendship with \"brother\" poet Paul Celan is often noted today. Their bond was described in one of Celan's most famous poems, \"\" (\"Zürich, The Stork Inn\"). Sachs and Celan shared the Holocaust and the fate of the Jews throughout history, their interest in Jewish and Christian beliefs and practices, and their literary models; their imagery was often remarkably similar, though developed independently. Their friendship was supportive during professional conflicts. Celan also suffered from artistic infighting (Claire Goll's accusations of plagiarism) during a period of frustration with his work's reception. When Sachs met Celan she was embroiled in a long dispute with Finnish-Jewish composer over his adaptation of her play \"\". In Celan she found someone who understood her anxiety and hardships as an artist. Sachs's poetry is intensely lyrical and reflects some influence by German Romanticism, especially in her early work. The poetry she wrote as a young woman in Berlin is more inspired by Christianity than Judaism and makes use of traditional Romantic imagery and themes. Much of it concerns an unhappy love affair Sachs suffered in her teens with a non-Jewish man who would eventually be killed in a concentration camp. After Sachs learned of her only love interest's death, she bound up his fate with that of her people and wrote many love lyrics ending not only in the beloved's death, but in the catastrophe of the Holocaust. Sachs herself mourns no longer as a jilted lover but as a personification of the Jewish people in their vexed relationship to history and God. Her fusion of grief with subtly romantic elements is in keeping with the imagery of the kabbalah, where the Shekhinah represents God's presence on earth and mourns for the separation of God from His people in their suffering. Thus Sachs's Romanticism allowed her to develop self-consciously from a German to a Jewish writer, with a corresponding change in her language: still flowery and conventional in some of her first poetry on the Holocaust, it becomes ever more compressed and surreal, returning to a series of the same images and tropes (dust, stars, breath, stones and jewels, blood, dancers, fish suffering out of water, madness, and ever-frustrated love) in ways that are sometimes comprehensible only to her readers, but always moving and disturbing. Though Sachs does not resemble many authors, she appears to have been influenced by Gertrud Kolmar and Else Lasker-Schüler in addition to Celan. In 1961 Sachs won the first Nelly Sachs Prize, a literary award given biennially by the German city of Dortmund and named in her honour. When, with Shmuel Yosef Agnon, she was awarded the 1966 Nobel Prize in Literature, she observed that Agnon represented Israel whereas \"I represent the tragedy of the Jewish people.\" She read her poem \"In der Flucht\" at the ceremony.

The weapon had a hard pyramidal tip but the shank was sometimes made of softer iron. Some controversially believe that this softness would cause the shank to bend after impact, rendering the weapon useless to the enemy. Others believe that the pilum was not meant to bend after impact, but bending came from improper handling/removal of the weapon when it was stuck in an object. Also, if the \"pilum\" struck a shield it might embed itself, the bending of the shank would force the enemy to discard his shield as unusable without removing the \"pilum, \"which would be time consuming. Even if the shank did not bend, the pyramidal tip still made it difficult to pull out. However, there were many cases where the whole shank was hardened, making the \"pilum\" more suitable as a close quarters melee weapon, while also rendering it usable by enemy soldiers\".\" Although the bending of the \"pilum\"'s shank is commonly seen to be an integral part of the weapon's design and as an intentional feature, there is little evidence to suggest this. The most commonly found artifacts suggest that the \"pilum\" was constructed to use the weight of the weapon to cause damage, most likely to be able to impale through armour and reach the enemy soldier's body. The combination of the weapon's weight and the aforementioned pyramidal tip (the design of which would be seen in the Medieval era in the form of bodkin arrow tips), allowed the \"pilum\" to be a formidable armour-piercing weapon. Because the weapon was meant to be used against armour and use its mass, as opposed to its speed, to cause damage, the bending of the shank seems to be a beneficial result of its intended use, which is to pierce through layers of armour. That the \"pilum\" needed to pierce layers of armour (through the shield, into body-armour, and past clothing) necessitated a lengthy shank, which was prone to bending. In one work, M.C. Bishop wrote that the momentum of the \"pilum\" caused the shank to bend upon impact, and, although unintended, this proved to be a useful characteristic of the weapon. However, a newer work by M. C. Bishop states that the \"pilum\" is \"unlikely to bend under their own weight when thrown and striking a target or ground\" - rather, it is human intervention [e.g., improper removal of a pilum stuck in a target] that is responsible in some way, and that Caesar's writings should be interpreted as the \"pilum\" bent when soldiers tried to remove them. Since the pyramidal tip of a \"pilum\" was wider than the rest of the shank, once it penetrated a shield, it left behind a hole larger than the rest of the shank, and it could move through the shield with little resistance, stabbing the soldier behind. The length of the shank and its depth of penetration also made it hard to pull out of a shield even if it failed to bend. If the bearer of the shield was charging and a \"pilum\" penetrated the shield, the end of the heavy shaft of the \"pilum\" would hit the ground, holding the shield in place. On some \"pila\" there was a spike on the end of the shaft which made it easier to dig into the ground. \"Pila\" were divided into two models: heavy and light. Pictorial evidence suggests that some versions of the weapon were weighted by a lead ball to increase penetrative power, but archaeological specimens of this design variant are not so far known. Recent experiments have shown \"pila\" to have a range of approximately, although the effective range is up to. The earliest known examples of the heavy version of the \"pila\" have barbed heads and their tangs have a figure-eight shape. The \"pilum\" is also capable of being used as, and was used as, a melee weapon in close quarters combat. This includes pictorial depictions from the Tropaeum Traiani monument, descriptions of Caesar's troops using javelins as pikes against the Gauls in Caesar's Gallic War, Book VII, and descriptions of Caesar's men using javelins to stab at Pompey's cavalry in \"Life of Caesar\" by Plutarch. The \"angon\" was a similar weapon used in late Roman and post-Roman times. The origin of the \"pilum\"'s design is a matter of contention. Arguments have been put forth which favour the design to be from ancient Italian tribes or from the Iberian peninsula. Considering that there are two versions of the \"pilum\" (the heavy and the light), it may be possible that the Roman \"pilum\" had, as ancestors, two different weapons, perhaps from different cultural groups. The two weapon designs may have coalesced into the form of the typical Roman \"pilum\", as it is known today.", "section_level": 1}, {"title": "Tactics.", "content": "Legionaries of the late republic and early empire often carried two \"pila\", with one sometimes being lighter than the other. Standard tactics called for Roman soldiers to throw one of them (both if time permitted) at the enemy, just before charging to engage with the \"gladius\"; however, Alexander Zhmodikov has argued that the Roman infantry could use \"pila\" at any stage in the fighting. The effect of the \"pila\" throw was to disrupt the enemy formation by attrition and by causing gaps to appear in its protective shield wall. \"Pila\" could also be used in hand-to-hand combat; one documented instance of this occurred at the Siege of Alesia, and another during Mark Antony's Parthian campaign. Additionally, \"pila\" could be employed as a thrusting implement and a barrier against cavalry charges.

His parents were both of Breton origin. After his father's death in 1908, his mother moved back to her native Locronan, Finistère, and he ended up spending much of his youth living with various relatives. In 1918, Tanguy briefly joined the merchant navy before being drafted into the Army, where he befriended Jacques Prévert. At the end of his military service in 1922, he returned to Paris, where he worked various odd jobs. He stumbled upon a painting by Giorgio de Chirico and was so deeply impressed he resolved to become a painter himself in spite of his complete lack of formal training. Tanguy had a habit of being completely absorbed by the current painting he was working on. This way of creating artwork may have been due to his very small studio which only had enough room for one wet piece. Through his friend Prévert, in around 1924 Tanguy was introduced into the circle of surrealist artists around André Breton. Tanguy quickly began to develop his own unique painting style, giving his first solo exhibition in Paris in 1927, and marrying his first wife Jeannette Ducrocq (1896-1977) later that same year. During this busy time of his life, Breton gave Tanguy a contract to paint 12 pieces a year. With his fixed income, he painted less and ended up creating only eight works of art for Breton. In December 1930, at an early screening of Buñuel and Dali's \"L'Age d'Or\", right-wing activists went to the lobby of the cinema where the film was being screened, and destroyed art works by Dalí, Joan Miró, Man Ray, Tanguy, and others. Throughout the 1930s, Tanguy adopted the bohemian lifestyle of the struggling artist with gusto, leading eventually to the failure of his first marriage. He had an intense affair with Peggy Guggenheim in 1938 when he went to London with his wife Jeannette Ducrocq to hang his first retrospective exhibition in Britain at her gallery \"Guggenheim Jeune\". The exhibition was a great success and Guggenheim wrote in her autobiography that \"Tanguy found himself rich for the first time in his life\". She purchased his pictures \"Toilette de L'Air\" and \"The Sun in Its Jewel Case\" (Le Soleil dans son écrin) for her collection. Tanguy also painted Peggy two beautiful earrings. The affair continued in both London and Paris and only finished when Tanguy met a fellow Surrealist artist who would become his second wife. In 1938, after seeing the work of fellow artist Kay Sage, Tanguy began a relationship which led to his second marriage. With the outbreak of World War II, Sage moved back to her native New York, and Tanguy, judged unfit for military service, followed her. He would spend the rest of his life in the United States. Sage and Tanguy were married in Reno, Nevada on August 17, 1940. Their marriage proved durable but tense. Both drank heavily, and Tanguy assaulted Sage verbally and sometimes physically, pushing her and sometimes even threatening her with a knife privately and at social gatherings. Sage, according to friends' accounts, made no response to her husband's aggression. Toward the end of the war, the couple moved to Woodbury, Connecticut, converting an old farmhouse into an artists' studio. They spent the rest of their lives there. In 1948, he became a naturalized citizen of the United States. In January 1955, Tanguy suffered a fatal stroke at Woodbury. His body was cremated and his ashes preserved until Sage's death in 1963. Later, his ashes were scattered by his friend Pierre Matisse on the beach at Douarnenez in his beloved Brittany, together with those of his wife.", "section_level": 1}, {"title": "Style and legacy.", "content": "Tanguy's paintings have a unique, immediately recognizable style of nonrepresentational surrealism. They show vast, abstract landscapes, mostly in a tightly limited palette of colors, only occasionally showing flashes of contrasting color accents. Typically, these alien landscapes are populated with various abstract shapes, sometimes angular and sharp as shards of glass, sometimes with an intriguingly organic look to them, like giant amoebae suddenly turned to stone. According to Nathalia Brodskaïa, \"Mama, Papa is Wounded!\" (1927) is one of Tanguy's most impressive paintings. Brodskaïa writes that the painting reflects his debt to Giorgio de Chirico – falling shadows and a classical torso – and conjures up a sense of doom: the horizon, the emptiness of the plain, the solitary plant, the smoke, the helplessness of the small figures. Tanguy said that it was an image he saw entirely in his imagination before starting to paint it. He also claimed he took the title of this and other works from psychiatric textbooks: \"I remember spending a whole afternoon with... André Breton,\" he said, \"leafing through books on psychiatry in the search for statements of patients which could be used as titles for paintings.\" Jennifer Mundy, however, discovered that the title of this painting and several others were taken from a book about paranormal phenomena, \"Traite de metaphysique\" (1922) by Dr Charles Richet. Tanguy's style was an important influence on several younger painters, such as Roberto Matta, Wolfgang Paalen, and Esteban Francés, who adopted a Surrealist style in the 1930s.

He developed an early appreciation of Rembrandt, German painters such as Lovis Corinth, and the Expressionists Oskar Kokoschka and Emil Nolde. In 1924 he enrolled in Leipzig University, where he studied philosophy and art history. He subsequently studied at the Fine Arts academy of Dresden, where he copied the paintings of the masters. The modern French and Spanish works he saw in 1926 at the Internationale Kunstausstellung in Dresden were a revelation to him, and he decided that he would leave his native country to prevent succumbing to provincialism. Consequently, after a bicycle trip through Italy, he moved to Paris. In Paris, Hartung had little contact with other artists, and copied the works of old and modern masters. He visited the south of France, where the landscape inspired him to a close study of the works of Cézanne, and he developed a great interest in principles of harmony and proportion such as the golden section. In 1928 he visited Munich where he studied painting technique with Max Doerner. In 1929 he married the artist Anna-Eva Bergman and established himself in the French towns of Leucate, and then in the Spanish Balearic Islands, eventually settling in Menorca. He exhibited for the first time in 1931 in Dresden. The death of his father in 1932 severed Hartung's last bonds with Germany. He was rejected from Nazi Germany on account of being a 'degenerate', because his painting style was associated with Cubism – an art movement incompatible with Nazi Germany's ideals. In 1935 when he attempted to sell paintings while visiting Berlin, the police tried to arrest him. He was able to flee the country with the help of his friend Christian Zervos. After he returned to Paris as a refugee, Hartung and his wife divorced, and he became depressed. His paintings were becoming more abstract and did not sell well. His friends tried to help him with his financial difficulties, and the sculptor Julio González offered him the use of his studio. In 1939 Hartung married González's daughter Roberta. In December 1939, he became a member of the French Foreign Legion. He was closely followed by the Gestapo and arrested for seven months by the French police. After they learned he was a painter, he was put in a red cell in an attempt to disturb his vision. After being released he rejoined the Legion to fight in North Africa, losing a leg in a battle near Belfort. He earned French citizenship in 1945, and was awarded the Croix de Guerre. In 1947 in Paris he had his first solo exhibition. By the late 1950s he had achieved recognition for his gestural paintings, which were nearly monochromatic and characterized by configurations of long rhythmical brushstrokes or scratches. In 1960 he was awarded the International for painting at the Venice Biennale. Hartung's freewheeling abstract paintings set influential precedents for many younger American painters of the sixties, making him an important forerunner of American Lyrical Abstraction of the 1960s and 1970s.

The root-mean-square value of the shot noise current \"i\" is given by the Schottky formula. where \"I\" is the DC current, \"q\" is the charge of an electron, and Δ\"B\" is the bandwidth in hertz. The Schottky formula assumes independent arrivals. Vacuum tubes exhibit shot noise because the electrons randomly leave the cathode and arrive at the anode (plate). A tube may not exhibit the full shot noise effect: the presence of a space charge tends to smooth out the arrival times (and thus reduce the randomness of the current). Pentodes and screen-grid tetrodes exhibit more noise than triodes because the cathode current splits randomly between the screen grid and the anode.

Noise may also be characterized by its probability distribution and noise spectral density \"N\"(\"f\") in watts per hertz. A noise signal is typically considered as a linear addition to a useful information signal. Typical signal quality measures involving noise are signal-to-noise ratio (SNR or \"S\"/\"N\"), signal-to-quantization noise ratio (SQNR) in analog-to-digital conversion and compression, peak signal-to-noise ratio (PSNR) in image and video coding, \"E\"/\"N\" in digital transmission, carrier to noise ratio (CNR) before the detector in carrier-modulated systems, and noise figure in cascaded amplifiers. Noise is a random process, characterized by stochastic properties such as its variance, distribution, and spectral density. The spectral distribution of noise can vary with frequency, so its power density is measured in watts per hertz (W/Hz). Since the power in a resistive element is proportional to the square of the voltage across it, noise voltage (density) can be described by taking the square root of the noise power density, resulting in volts per root hertz (formula_2). Integrated circuit devices, such as operational amplifiers commonly quote equivalent input noise level in these terms (at room temperature).

The importance of navigation in the Ob basin for transportation was particularly great before the completion of the Trans-Siberian Railway, since, despite the general south-to-north direction of the flow of Ob and most of its tributaries, the width of the Ob basin provided for (somewhat indirect) transportation in the east–west direction as well. Until the early 20th century, a particularly important western river-port was Tyumen, located on the Tura, a tributary of the Tobol. Reached by an extension of the Yekaterinburg-Perm railway in 1885, and thus obtaining a rail link to the Kama and Volga rivers in the heart of Russia, Tyumen became an important railhead for some years until the railway extended further east. In the eastern reaches of the Ob basin, Tomsk on the Tom functioned as an important terminus. Tyumen had its first steamboat in 1836, and steamboats have navigated the middle reaches of the Ob since 1845. The first steamboat on the Ob, Nikita Myasnikov's \"Osnova\", was launched in 1844; the early starts were difficult, and it was not until 1857 that steamboat shipping started developing in the Ob system in a serious way. Steamboats started operating on the Yenisei in 1863, on the Lena and Amur in the 1870s. In 1916 there were 49 steamers on the Ob; 10 on the Yenisei. In an attempt to extend the Ob navigable system even further, a system of canals, utilizing the Ket, long in all, was built in the late 19th-century to connect the Ob with the Yenisei, but soon abandoned as being uncompetitive with the railway. The Trans-Siberian Railway, once completed, provided for more direct, year-round transportation in the east–west direction. But the Ob river-system still remained important for connecting the huge expanses of Tyumen Oblast and Tomsk Oblast with the major cities along the Trans-Siberian route, such as Novosibirsk or Omsk. In the second half of the 20th century, construction of rail links to Labytnangi, Tobolsk, and the oil and gas cities of Surgut, and Nizhnevartovsk provided more railheads, but did not diminish the importance of the waterways for reaching places still not served by the rail.

However, like other forms of radioactive decay, it occurs due to quantum tunneling, without the atom having been struck by a neutron or other particle as in induced nuclear fission. Spontaneous fissions release neutrons as all fissions do, so if a critical mass is present, a spontaneous fission can initiate a self-sustaining chain reaction. Radioisotopes for which spontaneous fission is not negligible can be used as neutron sources. For example, californium-252 (half-life 2.645 years, SF branch ratio about 3.1 percent) can be used for this purpose. The neutrons released can be used to inspect airline luggage for hidden explosives, to gauge the moisture content of soil in highway and building construction, or to measure the moisture of materials stored in silos, for example. As long as the spontaneous fission gives a negligible reduction of the number of nuclei that can undergo such fission, this process can be approximated closely as a Poisson process. In this situation, for short time intervals the probability of a spontaneous fission is directly proportional to the length of time.

It should not be surprising that Adam, a speaker of German, might connect \"Balt-\" with \"Belt\", a word he was familiar with. However, linguistics has since established that Balt means \"white\". Many Baltic words contain the stem balt-, \"white\", which may also refer to shallow bodies of water including marshes. In Germanic languages there was some form of \"East Sea\" until after about 1600, when maps in English labeled it the \"Baltic Sea\". By 1840, the German nobles of the Governorate of Livonia adopted the term \"Balts\" to distinguish themselves from Germans of Germany. They spoke an exclusive dialect, Baltic German. For many, that was the “Baltic language” until 1919. In 1845, Georg Heinrich Ferdinand Nesselmann proposed a distinct language group for Latvian, Lithuanian and Old Prussian—Baltic.

Because the thousands of lakes and swamps in this area contributed to the Balts' geographical isolation, the Baltic languages retain a number of conservative or archaic features. Some of the major authorities on Balts, such as Kazimieras Būga, Max Vasmer, Vladimir Toporov and Oleg Trubachyov, in conducting etymological studies of eastern European river names, were able to identify in certain regions names of specifically Baltic provenance, which most likely indicate where the Balts lived in prehistoric times.

Over time the Balts became differentiated into Western and Eastern Balts.

They had abandoned their leather shop and travelled through Germany as itinerant actors, founding the Berlin theatre company \"Urania\", and turning their amateur passion into a profession. The young Lortzing's first stage appearance was at the age of 12, entertaining the audience with comic poems during the interval in the \"Kornhaus\" at the Freiburg Münster. From 1817, the Lortzing family were part of Josef Derossi ensemble in the Rhineland, treading the boards at Bonn, Düsseldorf, Barmen and Aachen. Albert Lortzing became an audience favourite, playing the roles of a youthful lover, a country boy and bon vivant, sometimes also singing small tenor or baritone roles. On 30 January 1824 he married the actress Rosina Regine Ahles, with whom he subsequently had 11 children. The couple belonged to the Hoftheater (court theatre) in Detmold from late 1826, which toured to Münster and Osnabrück. Lortzing joined the Freemasons, a popular refuge for artists in Metternich's police state. Lortzing composed an oratorio in Detmold, \"Die Himmelfahrt Christi\" (\"Christ's Ascension\"), which premiered in Münster, and predictably earned a rebuke for the young composer from the Münster regional governor, who claimed that Lortzing was \"a composer of no renown\". Lortzing composed the music for Christian Dietrich Grabbe's Don Juan und Faust, playing the role of Don Juan himself, with his wife as Donna Anna. Lortzing received a glowing report from an anonymous reviewer in a Frankfurt paper, who also mistakenly praised Lortzing for the text \"by this brilliant poet\". Grabbe, the real poet, was outraged, although the review did bring good publicity for the piece. On 3 November 1833 the young Lortzings gave their debut at the Leipziger Stadttheater. Lortzing's parents had been members of this ensemble since 1832, under Friedrich Sebald Ringelhardt. Here, Lortzing became a member of the artists' club \"\"Tunnel unter der Pleisse\"\" (\"Tunnel under the Pleiße\"), and in 1834 he became a member of the Leipzig Freemasons lodge \"\"Balduin zur Linde\"\" (\"Balduin to the Linden Tree\"). Lortzing was much loved in the Leipzig ensemble, particularly when acting in Johann Nestroy's comedies. However, his tendency to improvise and to deviate from the script attracted the attention of the theatrical police. His first comic opera, \"Zar und Zimmermann\", had a tough time with the Leipzig censors. It premiered in Leipzig on 22 December 1837. Lortzing himself sang the role of Peter Iwanow, but it did not make a major breakthrough until its Berlin performances in 1839, where it was much praised. In 1844, Lortzing became Kapellmeister of the Leipzig Stadttheater. After a quarrel with management, he was dismissed in April 1845 due to his \"rheumatic troubles\". The repeated protests of the public got him reinstated, but he was soon dismissed again after another argument. In an open letter, signed by almost everyone in the ensemble, he made a plea against the measures taken by the city government. Between 1846 and 1848, Lortzing worked as Kapellmeister at the Theater an der Wien in Vienna. At the behest of the Freedom Movement, he wrote text and music in 1848 for his political opera \"Regina\", named after his wife. This work concerned both labour struggles and fear of suicide. His last full-length opera was an 1849 fairy-tale satire of the Prussian military state called \"Rolands Knappen\" (\"Roland's Squire\"), featuring the repeated line \"And this is supposed to be a world order?\" (\"\"Und das soll eine Weltordnung sein?\"\") In 1848 he lost his appointment and had to return to work as a touring actor to support his large family. He worked at Gera and Lüneburg, among other cities. Finally in 1850, he became the Kapellmeister in Berlin at the newly opened Friedrich-Wilhelmstädtisches Theater. Lortzing also wrote music for masonic rituals. On 20 January 1851, the night his musical comedy \"Die Opernprobe\" premiered in Frankfurt, Lortzing suffered a stroke at his home in Berlin and died without medical treatment on the morning of the following day, under huge stress and deeply in debt. A number of luminaries from the musical world were present at his funeral, including Giacomo Meyerbeer, Heinrich Dorn, Wilhelm Taubert and Carl Friedrich Rungenhagen.

He went on to achieve moderate success as a novelist with a series of books exploring life in post-war Europe, but only upon publication of \"Job\" and \"Radetzky March\" did he achieve acclaim for his fiction rather than his journalism. From 1930, Roth's fiction became less concerned with contemporary society, with which he had become increasingly disillusioned, and began to evoke a melancholic nostalgia for life in imperial Central Europe before 1914. He often portrayed the fate of homeless wanderers looking for a place to live, in particular Jews and former citizens of the old Austria-Hungary, who, with the downfall of the monarchy, had lost their only possible \"Heimat\" (\"true home\"). In his later works, Roth appeared to wish that the monarchy could be restored. His longing for a more tolerant past may be partly explained as a reaction against the political extremism of the time, which culminated in Germany with National Socialism. The novel \"Radetzky March\" (1932) and the story \"The Bust of the Emperor\" (1935) are typical of this late phase. In another novel, \"The Emperor's Tomb\" (1938), Roth describes the fate of a cousin of the hero of \"Radetzky March\" up to Germany's annexation of Austria in 1938.

Shortly after Hitler's rise to power, in February 1933, Roth wrote in a prophetic letter to his friend, the Austrian writer Stefan Zweig: The relationship with Andrea Manga Bell failed due to financial problems and Roth's jealousy. From 1936 to 1938, Roth had a romantic relationship with Irmgard Keun. They worked together, traveling to various cities such as Paris, Wilna, Lemberg, Warsaw, Vienna, Salzburg, Brussels and Amsterdam. Without intending to deny his Jewish origins, Roth considered his relationship to Catholicism very important.

As the uplift was occurring some of mostly Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to the east. This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment.

Internal medicine delved into underlying pathological causes of symptoms and syndromes by use of laboratory investigations in addition to bedside clinical assessment of patients. In contrast, physicians in previous generations, such as the 17th-century physician Thomas Sydenham, who is known as the father of English medicine or \"the English Hippocrates\", had developed nosology (the study of diseases) via the clinical approach to diagnosis and management, by careful bedside study of the natural history of diseases and their treatment. Sydenham eschewed dissection of corpses and scrutiny of the internal workings of the body, for considering the internal mechanisms and causes of symptoms. It was thus subsequent to the 17th century that there was a rise in anatomical pathology and laboratory studies, with Giovanni Battista Morgagni, an Italian anatomist of the 18th century, being considered the father of anatomical pathology. Laboratory investigations became increasingly significant, with contribution of doctors including German physician and bacteriologist Robert Koch in the 19th century. The 19th century saw the rise of internal medicine that combined the clinical approach with use of investigations. Many early-20th-century American physicians studied medicine in Germany and brought this medical field to the United States. Thus, the name \"internal medicine\" was adopted in imitation of the existing German term.

They may manage serious acute illnesses that affect multiple organ systems at the same time in a single patient, and they may manage multiple chronic diseases or \"comorbidities\" that a single patient may have. General internal medicine specialists do not provide necessarily less expertise than single-organ specialists, rather, they are trained for a specific role of caring for patients with multiple simultaneous problems or complex comorbidities. Perhaps because it is complex to explain treatment of diseases that are not localised to a single-organ, there has been confusion about the meaning of internal medicine and the role of an \"internist.\" Internists are qualified physicians with postgraduate training in internal medicine and should not be confused with \"interns\", who are doctors in their first year of residency training (officially the term intern is no longer in use). Although internists may act as primary care physicians, they are not \"family physicians,\" \"family practitioners,\" or \"general practitioners,\" or \"GPs,\" whose training is not solely concentrated on adults and may include surgery, obstetrics, and pediatrics.

This period may be referred to as \"internship\", \"conditional registration\", or \"foundation programme\". Then, doctors may finally follow specialty training in internal medicine if they wish, typically being selected to training programs through competition. In North America, this period of postgraduate training is referred to as residency training, followed by an optional fellowship if the internist decides to train in a subspecialty. In the United States and in most countries, residency training for internal medicine lasts three years and centers on secondary and tertiary levels of care.

He was promoted to full membership on the Politburo in January 1926, a position which he retained until his death in 1946. When Yakov Mikhailovich Sverdlov died in March 1919 (from influenza, a beating or poisoning; sources differ), Kalinin replaced him as President of the All-Russian Central Executive Committee, the titular head of state of Soviet Russia. The name of this position was changed to Chairman of the Central Executive Committee of the USSR in 1922 and to Chairman of the Presidium of the Supreme Soviet in 1938. Kalinin continued to hold the post without interruption until his retirement at the end of World War II.

The lowly social origins were widely publicised in the official press, which habitually referred to Kalinin as the \"All-Union headman\" (Всесоюзный староста), a term hearkening to the village commune, in conjunction with his role as titular head of state. In practical terms, by the 1930s, Kalinin's role as a decision-maker in the Soviet government was nominal. He held little power or influence beyond receiving diplomatic letters from abroad. Recalling him, future Soviet leader Nikita Khrushchev said, \"I don't know what practical work Kalinin carried out under Lenin. But under Stalin he was the nominal signatory of all decrees, while in reality he rarely took part in government business. Sometimes he was made a member of a commission, but people didn't take his opinion into account very much.

The Romans established a presence after Julius Caesar defeated the local Aduatuci tribe. Namur came to prominence during the early Middle Ages when the Merovingians built a castle or citadel on the rocky spur overlooking the town at the confluence of the two rivers. In the 10th century, it became a county in its own right. The town developed somewhat unevenly, as the counts of Namur could only build on the north bank of the Meuse - the south bank was owned by the bishops of Liège and developed more slowly into the town of Jambes (now effectively a suburb of Namur). In 1262, Namur fell into the hands of the Count of Flanders, and was purchased by Duke Philip the Good of Burgundy in 1421. After Namur became part of the Spanish Netherlands in the 1640s, its citadel was considerably strengthened. Louis XIV of France invaded in 1692, capturing the town and annexing it to France. His renowned military engineer Vauban rebuilt the citadel. French control was short-lived, as William III of Orange-Nassau captured Namur only three years later in 1695 during the War of the Grand Alliance. Under the Barrier Treaty of 1709, the Dutch gained the right to garrison Namur, although the subsequent Treaty of Utrecht of 1713 gave control of the formerly Spanish Netherlands to the Austrian House of Habsburg. Thus, although the Austrians ruled the town, the citadel was controlled by the Dutch. It was rebuilt again under their tenure. General Jean-Baptiste Cyrus de Valence's column laid siege to the city on 19 November 1792 during the War of the First Coalition and, after 12 days, the city surrendered on 1 December and its whole garrison of 3,000 men was taken prisoner. France invaded the region again in 1794, annexing Namur and imposing a repressive regime. After the defeat of Napoleon in 1815, the Congress of Vienna incorporated what is now Belgium into the United Kingdom of the Netherlands. Belgium broke away from the Netherlands in 1830 following the Belgian Revolution, and Namur continued to be a major garrison town under the new government. The citadel was rebuilt yet again in 1887. Namur was a major target of the German invasion of Belgium in 1914, which sought to use the Meuse valley as a route into France. On August 21, 1914, the Germans bombarded the town of Namur without warning. Several people were killed. Despite being billed as virtually impregnable, the citadel fell after only three days' fighting and the town was occupied by the Germans for the rest of the war. Namur fared little better in World War II; it was in the front lines of both the Battle of the Ardennes in 1940 and the Battle of the Bulge in 1944. The town suffered heavy damage in both wars.

He was one of the commission of twenty that carried out the great agrarian scheme of Caesar for the resettlement of Capua and Campania (59 BC). During Caesar's civil war he commanded one of Pompey's armies in the Ilerda campaign. He escaped the penalties of being on the losing side in the civil war through two pardons granted by Julius Caesar, before and after the Battle of Pharsalus. Caesar later appointed him to oversee the public library of Rome in 47 BC, but following Caesar's death Mark Antony proscribed him, resulting in the loss of much of his property, including his library. As the Republic gave way to Empire, Varro gained the favour of Augustus, under whose protection he found the security and quiet to devote himself to study and writing. Varro studied under the Roman philologist Lucius Aelius Stilo, and later at Athens under the Academic philosopher Antiochus of Ascalon. Varro proved to be a highly productive writer and turned out more than 74 Latin works on a variety of topics.

His \"Nine Books of Disciplines\" became a model for later encyclopedists, especially Pliny the Elder.

Varro decided to focus on identifying nine of these arts: grammar, rhetoric, logic, arithmetic, geometry, astronomy, musical theory, medicine, and architecture. Using Varro's list, subsequent writers defined the seven classical \"liberal arts of the medieval schools\". In 37 BC, in his old age, he also wrote on agriculture for his wife Fundania, writing a \"voluminous\" work \"De re rustica\" (also called \"Res rusticae\")—similar to Cato the Elder's similar work \"De agri cultura\"—on the management of large slave-run estates.", "section_level": 1}, {"title": "Calendars.", "content": "The compilation of the \"Varronian chronology\" was an attempt to determine an exact year-by-year timeline of Roman history up to his time.

Electrum is believed to have been used in coins c.600 BC in Lydia during the reign of Alyattes. Electrum was much better for coinage than gold, mostly because it was harder and more durable, but also because techniques for refining gold were not widespread at the time. The discrepancy between gold content of electrum from modern Western Anatolia (70–90%) and ancient Lydian coinage (45–55%) suggests that the Lydians had already solved the refining technology for silver and were adding refined silver to the local native electrum some decades before introducing the pure silver coins cited below. In Lydia, electrum was minted into coins weighing, each valued at 1/3 \"stater\" (meaning \"standard\"). Three of these coins—with a weight of about —totaled one stater, about one month's pay for a soldier. To complement the stater, fractions were made: the \"trite\" (third), the \"hekte\" (sixth), and so forth, including 1/24 of a stater, and even down to 1/48 and 1/96 of a stater. The 1/96 stater was only about to. Larger denominations, such as a one stater coin, were minted as well. Because of variation in the composition of electrum, it was difficult to determine the exact worth of each coin. Widespread trading was hampered by this problem, as the intrinsic value of each electrum coin could not be easily determined. These difficulties were eliminated circa 570 BC when the Croeseids, coins of pure gold and silver were introduced. However, electrum currency remained common until approximately 350 BC.

Archaeological research indicates that Baltic tribes had settlements at the mouth of Vitba. In the 9th century, Slavic settlements of the tribal union of the Krivichs replaced them. According to the \"Chronicle of Michael Brigandine\" (1760), Princess Olga of Kiev founded Vitebsk (also recorded as Dbesk, Vidbesk, Videbsk, Vitepesk, or Vicibesk) in 974. Other versions give 947 or 914. Academician Boris Rybakov and historian Leonid Alekseyev have come to the conclusion, based on the chronicles, that Princess Olga of Kiev could have established Vitebsk in 947. Leonid Alekseyev suggested that the chroniclers, when transferring the date from the account of the Byzantine era (since the creation of the world) to a new era, obtained the year 947, later mistakenly written in copying manuscripts as 974. An important place on trade route from the Varangians to the Greeks, Vitebsk became by the end of the 12th century a center of trade and commerce, and the center of an independent principality, following Polotsk, and at times, Smolensk and Kiev princes. The official year of the founding of Vitebsk is 974, based on an anachronistic legend of founding by Olga of Kiev, but the first mention in historical records dates from 1021, when Yaroslav the Wise of Kiev gave it to Bryachislav Izyaslavich, Prince of Polotsk. In the 12th and 13th centuries Vitebsk functioned as the capital of the Principality of Vitebsk, an appanage principality which thrived at the crossroads of the river routes between the Baltic and Black seas. In 1320 the city was incorporated into the Grand Duchy of Lithuania as dowry of the Princess Maria, the first wife of Grand Duke of Lithuania Algirdas. By 1351 the city had erected a stone Upper and Lower Castle, the prince's palace. In 1410 Vitebsk participated in the Battle of Grunwald. In 1569 it became a part of Polish-Lithuanian Commonwealth. In 1597 the townsfolk of Vitebsk were privileged with Magdeburg rights. However, the rights were taken away in 1623 after the citizens revolted against the imposed Union of Brest and killed Archbishop Josaphat Kuntsevych of Polotsk. The city was almost completely destroyed in 1708, during the Great Northern War. In the First Partition of Poland in 1772, the Russian Empire annexed Vitebsk. Under the Russian Empire the historic centre of Vitebsk was rebuilt in the Neoclassical style.

The most famous of its Jewish natives was the painter Marc Chagall (1887-1985). In 1919 Vitebsk was proclaimed to be part of the Socialist Soviet Republic of Byelorussia (January to February 1919), but was soon transferred to the Russian Soviet Federative Socialist Republic and later to the short-lived Lithuanian–Byelorussian Soviet Socialist Republic (February to July 1919). In 1924 it was returned to the Byelorussian Soviet Socialist Republic. During World War II the city came under Nazi German occupation (11 July 1941 – 26 June 1944).

Defendants ranged from members of the SS to \"kapos,\" privileged prisoners responsible for low-level control of camp internees, and included some of those responsible for the process of \"selection,\" or determination of who should be sent to the gas chambers directly from the \"ramp\" upon disembarking the trains that brought them from across Europe (\"selection\" generally entailed inclusion of all children held to be ineligible for work, generally under the age of 14, and any mothers unwilling to part with their \"selected\" children). In the course of the trial, approximately 360 witnesses were called, including around 210 survivors. Proceedings began in the \"Bürgerhaus Gallus\", in Frankfurt am Main, which was converted into a courthouse for that purpose, and remained there until their conclusion. State Attorney General (Hessian Generalstaatsanwalt) Fritz Bauer, himself briefly interned in 1933 at the Heuberg concentration camp, led the prosecution. Bauer was concerned with pursuing individual defendants serving at Auschwitz-Birkenau; only 22 SS members were charged of an estimated 6,000 to 8,000 thought to have been involved in the administration and operation of the camp. The men on trial in Frankfurt were tried only for murders and other crimes that they committed on their own initiative at Auschwitz and were not tried for genocidal actions perpetrated \"when following orders\", considered by the courts to be the lesser crime of accomplice to murder. At a 1963 trial, KGB assassin Bohdan Stashynsky, who had committed several murders in the Federal Republic in the 1950s, was found by a German court not legally guilty of murder. Instead, Stashynsky was found to be only an accomplice to murder as the courts ruled that the responsibility for his murders rested only with his superiors in the KGB who had given him his orders. The legal implication of the Stashynsky case were that the courts had ruled that in a totalitarian system only executive decision-makers could be convicted of murder and that anyone who followed orders and killed someone could be convicted only of being accomplices to murder. The term executive decision-maker was so defined by the courts to apply only to the highest levels of the \"Reich\" leadership during the National Socialist period, and that all who just followed orders when killing were just accomplices to murder. Someone could be only convicted of murder if it was shown that they had killed someone on their own initiative, and thus all of the accused of murder at the Auschwitz trial were tried only for murders that they had done on their own initiative. Thus, Bauer could only indict for murder those who killed when not following orders, and those who had killed while following orders could be indicted as accomplices to murder. Moreover, because of the legal distinction between murderers and accomplices to murder, this meant that an SS man who killed thousands while operating the gas chambers at Auschwitz could only be found guilty of being accomplice to murder because he had been following orders, while an SS man who had beaten one inmate to death on his own initiative could be convicted of murder because he had not been following orders. Bauer is said to have been opposed in the former purpose by the young Helmut Kohl, then a junior member of the Christian Democratic Union. In furtherance of that purpose Bauer sought and received support from the Institute for Contemporary History in Munich. The following historians from the Institute served as expert witnesses for the prosecution; Helmut Krausnick, Hans-Adolf Jacobsen, Hans Buchheim, and Martin Broszat. Subsequently, the information the four historians gathered for the prosecution served as the basis for their 1968 book, \"Anatomy of the SS State\", the first thorough survey of the SS based on SS records. Information about the actions of those accused and their whereabouts had been in the possession of West German authorities since 1958, but action on their cases was delayed by jurisdictional disputes, among other considerations.

With the exception of a few kilobytes of overhead, each DOS application could use any available low memory before Windows was started. Windows/386 ran Windows applications in a single Virtual 8086 box, with EMS emulation. In contrast, Windows 3.0 in standard or enhanced mode ran Windows applications in 16 bits protected mode segments. Windows/386 also provided EMS emulation, using the memory management features of the 80386 to make RAM beyond 640k behave like the banked memory previously only supplied by add-in cards and used by popular DOS applications. (By overwriting the WIN200.BIN file with COMMAND.COM, it is possible to use the EMS emulation in DOS without starting the Windows GUI.) There was no support for disk-based virtual memory, so multiple DOS programs had to fit inside the available physical memory; therefore, Microsoft suggested buying additional memory and cards if necessary. Neither of these versions worked with DOS memory managers like CEMM or QEMM or with DOS extenders, which have their own extended memory management and run in protected mode as well.

This timing may account for the ancient church's establishment of September 1 as the beginning of the liturgical year, despite the official Roman New Year's Day of January 1 in the Julian calendar, because the indiction was the principal means for counting years in the empires, apart from the reigns of the Emperors. The September 1 date prevailed throughout all of Christendom for many centuries, until subsequent divisions eventually produced revisions in some places. After the sack of Rome in 410, communications and travel between east and west deteriorated. Liturgical developments in Rome and Constantinople did not always match, although a rigid adherence to form was never mandated in the church. Nevertheless, the principal points of development were maintained between east and west. The Roman and Constantinopolitan liturgical calendars remained compatible even after the East-West Schism in 1054. Separations between the Roman Catholic ecclesiastical year and Eastern Orthodox liturgical calendar grew only over several centuries' time. During those intervening centuries, the Roman Catholic ecclesiastic year was moved to the first day of Advent, the Sunday nearest to St. Andrew's Day (November 30). According to the Latin Rite of the Catholic Church, the liturgical year begins at 4:00 PM on Saturday preceding the fourth Sunday prior to December 25 (between November 26 and December 2). By the time of the Reformation (early 16th century), the Roman Catholic general calendar provided the initial basis for the calendars for the liturgically-oriented Protestants, including the Anglican and Lutheran Churches, who inherited this observation of the liturgical new year. The present-day Eastern Orthodox liturgical calendar is the virtual culmination of the ancient eastern development cycle, though it includes later additions based on subsequent history and lives of saints. It still begins on September 1, proceeding annually into the Nativity of the Theotokos (September 8) and Exaltation of the Cross (September 14) to the celebration of Nativity of Christ (Christmas), through his death and resurrection (Pascha/Easter), to his Ascension and the Dormition of the Theotokos (\"falling asleep\" of the Virgin Mary, August 15). This last feast is known in the Roman Catholic church as the Assumption. The dating of \"September 1\" is according to the \"new\" (revised) Julian calendar or the \"old\" (standard) Julian calendar, depending on which is used by a particular Orthodox Church. Hence, it may fall on 1 September on the civil calendar, or on 14 September (between 1900 and 2099 inclusive). The Coptic and Ethiopian liturgical calendars are unrelated to these systems but instead follow the Alexandrian calendar which fixed the wandering ancient Egyptian calendar to the Julian year.

At that time, this was the date on which those who were to hold civil office assumed their official position, and it was also the traditional annual date for the convening of the Roman Senate. This civil new year remained in effect throughout the Roman Empire, east and west, during its lifetime and well after, wherever the Julian calendar continued in use.

While the reintroduction of Christianity brought the Julian calendar with it, its use was primarily in the service of the church to begin with.

In combination with ornamental decoration these techniques formed an alternative to the prevailing painting of walls. Of late there has been an unmistakable growing interest in this old technique. The technical procedure is relatively simple, and the procedures are similar to the painting of frescoes. Sgraffito played a significant role during the Italian Renaissance, with two of Raphael's workshop, Polidoro da Caravaggio and his partner Maturino da Firenze, among the leading specialists, painting palace facades in Rome and other cities. Most of their work has now weathered away. During the 16th century, the technique was brought to Germany by the master builders of the Renaissance and taken up with enthusiasm. As a simple native art, old examples of sgraffito can be found in the wide surroundings of Wetterau and Marburg. In Germany, the technique is most predominant in Bavaria. The use of sgraffito was common in the creation of housing façades for the purposes of advertising. The technique was also used in Thuringia, the Engadin, Austria and Transylvania. In Catalonia, sgraffito was implemented in the early 20th century by the Noucentista neo-classical architects and became a recurrent technique in façade decoration. Another use of sgraffito is seen in its simplified painting technique. One coat of paint is left to dry on a canvas or sheet of paper.

This bacterium is found in root nodules, which may be as large as a human fist, with many small lobes, and light brown in colour. The bacterium absorbs nitrogen from the air and makes it available to the tree. Alder, in turn, provides the bacterium with sugars, which it produces through photosynthesis. As a result of this mutually beneficial relationship, alder improves the fertility of the soil where it grows, and as a pioneer species, it helps provide additional nitrogen for the successional species which follow. Because of its abundance, red alder delivers large amounts of nitrogen to enrich forest soils. Red alder stands have been found to supply between 120 and 290 pounds of nitrogen per acre (130 to 320 kg per ha) annually to the soil. From Alaska to Oregon, \"Alnus viridis\" subsp. \"sinuata\" (\"A. sinuata\", Sitka Alder or Slide Alder), characteristically pioneer fresh, gravelly sites at the foot of retreating glaciers. Studies show that Sitka alder, a more shrubby variety of alder, adds nitrogen to the soil at an average of 55 pounds per acre (60 kg per ha) per year, helping convert the sterile glacial terrain to soil capable of supporting a conifer forest. Alders are common among the first species to colonize disturbed areas from floods, windstorms, fires, landslides, etc. Alder groves themselves often serve as natural firebreaks since these broad-leaved trees are much less flammable than conifers. Their foliage and leaf litter does not carry a fire well, and their thin bark is sufficiently resistant to protect them from light surface fires. In addition, the light weight of alder seeds (650,000 per pound, or 1.5 million per kg) allows for easy dispersal by the wind. Although it outgrows coastal Douglas-fir for the first 25 years, it is very shade intolerant and seldom lives more than 100 years. Red alder is the Pacific Northwest's largest alder and the most plentiful and commercially important broad-leaved tree in the coastal Northwest. Groves of red alder 10 to 20 inches (25 to 50 cm) in diameter intermingle with young Douglas-fir forests west of the Cascades, attaining a maximum height of 100 to 110 feet (30 to 33 m) in about sixty years and then lose vigor as heart rot sets in.

Most of the pilings that form the foundation of Venice were made from alder trees. Alder bark contains the anti-inflammatory salicin, which is metabolized into salicylic acid in the body. Some Native American cultures use red alder bark (\"Alnus rubra\") to treat poison oak, insect bites, and skin irritations.

The refractive index of many materials (such as glass) varies with the wavelength or color of the light used, a phenomenon known as \"dispersion\". This causes light of different colors to be refracted differently and to leave the prism at different angles, creating an effect similar to a rainbow. This can be used to separate a beam of white light into its constituent spectrum of colors. A similar separation happens with iridescent materials, such as a soap bubble. Prisms will generally disperse light over a much larger frequency bandwidth than diffraction gratings, making them useful for broad-spectrum spectroscopy. Furthermore, prisms do not suffer from complications arising from overlapping spectral orders, which all gratings have. Prisms are sometimes used for the internal reflection at the surfaces rather than for dispersion.

This inconsistency caused confusion amongst later geometricians. René Descartes had seen light separated into the colors of the rainbow by glass or water, though the source of the color was unknown. Isaac Newton's 1666 experiment of bending white light through a prism demonstrated that all the colors already existed in the light, with different color \"corpuscles\" fanning out and traveling with different speeds through the prism. It was only later that Young and Fresnel combined Newton's particle theory with Huygens' wave theory to explain how color arises from the spectrum of light. Newton arrived at his conclusion by passing the red color from one prism through a second prism and found the color unchanged. From this, he concluded that the colors must already be present in the incoming light — thus, the prism did not create colors, but merely separated colors that are already there. He also used a lens and a second prism to recompose the spectrum back into white light. This experiment has become a classic example of the methodology introduced during the scientific revolution. The results of the experiment dramatically transformed the field of metaphysics, leading to John Locke's primary vs secondary quality distinction.

Ash is a minor material for electric guitar bodies and, less commonly, for acoustic guitar bodies, known for its bright, cutting edge and sustaining quality. Some Fender Stratocasters and Telecasters are made of ash, (such as Bruce Springsteen's Telecaster on the Born to Run album cover), as an alternative to alder. They are also used for making drum shells. Woodworkers generally consider ash a \"poor cousin\" to the other major open pore wood, oak, but it is useful in any furniture application. Ash veneers are extensively used in office furniture. Ash is not used much outdoors due to the heartwood having a low durability to ground contact, meaning it will typically perish within five years. The \"F. japonica\" species is favored as a material for making baseball bats by Japanese sporting-goods manufacturers. Its robust structure, good looks, and flexibility combine to make ash ideal for staircases. Ash stairs are extremely hard-wearing, which is particularly important for treads. Due to its elasticity, ash can also be steamed and bent to produce curved stair parts such as volutes (curled sections of handrail) and intricately shaped balusters. However, a reduction in the supply of healthy trees, especially in Europe, is making ash an increasingly expensive option. Ash was commonly used for the structural members of the bodies of cars made by carriage builders. Early cars had frames which were intended to flex as part of the suspension system to simplify construction. The Morgan Motor Company of Great Britain still manufacture sports cars with frames made from ash. It was also widely used by early aviation pioneers for aircraft construction. It lights and burns easily, so is used for starting fires and barbecues, and is usable for maintaining a fire, though it produces only a moderate heat. The two most economically important species for wood production are white ash, in eastern North America, and European ash in Europe. The green ash (\"F. pennsylvanica\") is widely planted as a street tree in the United States. The inner bark of the blue ash (\"F. quadrangulata\") has been used as a source for blue dye.

Former Havas employees founded Reuters in 1851 in Britain and Wolff in 1849 in Germany; Havas is now Agence France-Presse (AFP). For international news, the agencies pooled their resources, so that Havas, for example, covered the French Empire, South America and the Balkans and shared the news with the other national agencies. In France the typical contract with Havas provided a provincial newspaper with 1800 lines of telegraphed text daily, for an annual subscription rate of 10,000 francs. Other agencies provided features and fiction for their subscribers. In the 1830s, France had several specialized agencies. Agence Havas was founded in 1835 by a Parisian translator and advertising agent, Charles-Louis Havas, to supply news about France to foreign customers. In the 1840s, Havas gradually incorporated other French agencies into his agency. Agence Havas evolved into Agence France-Presse (AFP). Two of his employees, Bernhard Wolff and Paul Julius Reuter, later set up rival news agencies, Wolffs Telegraphisches Bureau in 1849 in Berlin and Reuters in 1851 in London. Guglielmo Stefani founded the Agenzia Stefani, which became the most important press agency in Italy from the mid-19th century to World War II, in Turin in 1853. The development of the telegraph in the 1850s led to the creation of strong national agencies in England, Germany, Austria and the United States. But despite the efforts of governments, through telegraph laws such as in 1878 in France, inspired by the British Telegraph Act of 1869 which paved the way for the nationalisation of telegraph companies and their operations, the cost of telegraphy remained high. In the United States, the judgment in \"Inter Ocean Publishing v. Associated Press\" facilitated competition by requiring agencies to accept all newspapers wishing to join. As a result of the increasing newspapers, the Associated Press was now challenged by the creation of United Press Associations in 1907 and International News Service by newspaper publisher William Randolph Hearst in 1909. Driven by the huge U.S. domestic market, boosted by the runaway success of radio, all three major agencies required the dismantling of the \"cartel agencies\" through the Agreement of 26 August 1927. They were concerned about the success of U.S. agencies from other European countries which sought to create national agencies after the First World War. Reuters had been weakened by war censorship, which promoted the creation of newspaper cooperatives in the Commonwealth and national agencies in Asia, two of its strong areas. After the Second World War, the movement for the creation of national agencies accelerated, when accessing the independence of former colonies, the national agencies were operated by the State. Reuters, became cooperative, managed a breakthrough in finance, and helped to reduce the number of U.S. agencies from three to one, along with the internationalization of the Spanish EFE and the globalization of Agence France-Presse. In 1924, Benito Mussolini placed Agenzia Stefani under the direction of Manlio Morgagni, who expanded the agency's reach significantly both within Italy and abroad. Agenzia Stefani was dissolved in 1945, and its technical structure and organization were transferred to the new Agenzia Nazionale Stampa Associata (ANSA). Wolffs was taken over by the Nazi regime in 1934, and Reuters continues to operate as a major international news agency today. In 1865, Reuter and Wolff signed agreements with Havas's sons, forming a cartel designating exclusive reporting zones for each of their agencies within Europe.

It is similar to, but distinct from, market depth, which relates to the trade-off between quantity being sold and the price it can be sold for, rather than the liquidity trade-off between speed of sale and the price it can be sold for. A market may be considered both deep and liquid if there are ready and willing buyers and sellers in large quantities. An illiquid asset is an asset which is not readily salable (without a drastic price reduction, and sometimes not at any price) due to uncertainty about its value or the lack of a market in which it is regularly traded. The mortgage-related assets which resulted in the subprime mortgage crisis are examples of illiquid assets, as their value was not readily determinable despite being secured by real property. Before the crisis, they had moderate liquidity because it was believed that their value was generally known. Speculators and market makers are key contributors to the liquidity of a market or asset. Speculators are individuals or institutions that seek to profit from anticipated increases or decreases in a particular market price. Market makers seek to profit by charging for the immediacy of execution: either implicitly by earning a bid/ask spread or explicitly by charging execution commissions. By doing this, they provide the capital needed to facilitate the liquidity. The risk of illiquidity does not apply only to individual investments: whole portfolios are subject to market risk.

Contingent liquidity risk is the risk associated with finding additional funds or replacing maturing liabilities under potential, future stressed market conditions. When a central bank tries to influence the liquidity (supply) of money, this process is known as open market operations.", "section_level": 1}, {"title": "Effect on asset values.", "content": "The market liquidity of assets affects their prices and expected returns. Theory and empirical evidence suggests that investors require higher return on assets with lower market liquidity to compensate them for the higher cost of trading these assets. That is, for an asset with given cash flow, the higher its market liquidity, the higher its price and the lower is its expected return. In addition, risk-averse investors require higher expected return if the asset's market-liquidity risk is greater. This risk involves the exposure of the asset return to shocks in overall market liquidity, the exposure of the asset's own liquidity to shocks in market liquidity and the effect of market return on the asset's own liquidity. Here too, the higher the liquidity risk, the higher the expected return on the asset or the lower is its price. One example of this is a comparison of assets with and without a liquid secondary market. The liquidity discount is the reduced promised yield or expected return for such assets, like the difference between newly issued U.S. Treasury bonds compared to off the run treasuries with the same term to maturity. Initial buyers know that other investors are less willing to buy off-the-run treasuries, so the newly issued bonds have a higher price (and hence lower yield).", "section_level": 1}, {"title": "Futures.", "content": "In the futures markets, there is no assurance that a liquid market may exist for offsetting a commodity contract at all times.

Managing liquidity is a daily process requiring bankers to monitor and project cash flows to ensure adequate liquidity is maintained. Maintaining a balance between short-term assets and short-term liabilities is critical. For an individual bank, clients' deposits are its primary liabilities (in the sense that the bank is meant to give back all client deposits on demand), whereas reserves and loans are its primary assets (in the sense that these loans are owed to the bank, not by the bank). The investment portfolio represents a smaller portion of assets, and serves as the primary source of liquidity. Investment securities can be liquidated to satisfy deposit withdrawals and increased loan demand. Banks have several additional options for generating liquidity, such as selling loans, borrowing from other banks, borrowing from a central bank, such as the US Federal Reserve bank, and raising additional capital. In a worst-case scenario, depositors may demand their funds when the bank is unable to generate adequate cash without incurring substantial financial losses. In severe cases, this may result in a bank run. Most banks are subject to legally mandated requirements intended to help avoid a liquidity crisis. Banks can generally maintain as much liquidity as desired because bank deposits are insured by governments in most developed countries. A lack of liquidity can be remedied by raising deposit rates and effectively marketing deposit products. However, an important measure of a bank's value and success is the cost of liquidity. A bank can attract significant liquid funds. Lower costs generate stronger profits, more stability, and more confidence among depositors, investors, and regulators.", "section_level": 1}, {"title": "Stock market.", "content": "In the market, liquidity has a slightly different meaning. The market for a stock is said to be liquid if the shares can be rapidly sold and the act of selling has little impact on the stock's price. Generally, this translates to where the shares are traded and the level of interest that investors have in the company. Another way to judge liquidity in a company's stock is to look at the bid/ask spread. For liquid stocks, such as Microsoft or General Electric, the spread is often just a few pennies – much less than 1% of the price. For illiquid stocks, the spread can be much larger, amounting to a few percent of the trading price. Liquidity positively impacts the stock market. When stock prices rise, it is said to be due to a confluence of extraordinarily high levels of liquidity on household and business balance sheets, combined with a simultaneous normalization of liquidity preferences.

It is an implementation of dozens of services and a dozen protocols, including: All these services and protocols are frequently incorrectly referred to as just NetBIOS or SMB. The NBT (NetBIOS over TCP/IP) and WINS protocols, and their underlying SMB version 1 protocol, are deprecated on Windows. Since Windows Vista the WS-Discovery protocol has been included along with SMB2 and its successors, which supersede these. (WS-Discovery is implemented on Unix-like platforms by third party daemons which allow Samba shares to be discovered when the deprecated protocols are disabled). Samba sets up network shares for chosen Unix directories (including all contained subdirectories). These appear to Microsoft Windows users as normal Windows folders accessible via the network. Unix users can either mount the shares directly as part of their file structure using the mount.cifs command or, alternatively, can use a utility, smbclient (libsmb) installed with Samba to read the shares with a similar interface to a standard command line FTP program. Each directory can have different access privileges overlaid on top of the normal Unix file protections. For example: home directories would have read/write access for all known users, allowing each to access their own files. However they would still not have access to the files of others unless that permission would normally exist. Note that the netlogon share, typically distributed as a read only share from /etc/samba/netlogon, is the logon directory for user logon scripts. Samba services are implemented as two daemons: Samba configuration is achieved by editing a single file (typically installed as /etc/smb.conf or /etc/samba/smb.conf). Samba can also provide user logon scripts and group policy implementation through poledit. Samba is included in most Linux distributions and is started during the boot process. On Red Hat, for instance, the /etc/rc.d/init.d/smb script runs at boot time, and starts both daemons.

Development has been minimal, due to a lack of developers. The Samba TNG team frequently directed potential users towards Samba because of its better support and development. A key goal of the Samba TNG project was to rewrite all of the NT Domains services as FreeDCE projects. This was made difficult as the services were developed manually through network reverse-engineering, with limited or no reference to DCE/RPC documentation. A key difference from Samba was in the implementation of the NT Domains suite of protocols and MSRPC services. Samba makes all the NT Domains services available from a single place, whereas Samba TNG separated each service into its own program. ReactOS started using Samba TNG services for its SMB implementation.

The new car had a more powerful version of the three-cylinder two-stroke engine driving the front wheels and a completely new body. By this time, Germany had been divided into two countries (the West and the East) and the Wartburg factory was in the communist East (GDR). Exports to West Germany began in 1958, and by the early 1960s the car was exported to other countries, including the United Kingdom and United States. Right hand drive models were first manufactured in 1963 and exported to Cyprus, with British buyers being introduced to the car in 1964. However, just 550 examples (450 saloons and 100 estates) were sold in the UK. These were two-tone models sold at the same price as a basic British Mini, appealing mostly to older people. The 311 model was manufactured in a number of variations, including pickup, estate, and two-seater roadster. A convertible was advertised in the GDR in 1957 but its production never exceeded 350 units. The engine was enlarged to 992 cc in 1962 and a completely new body was manufactured after 1966. This version, the 353, was sold as the Wartburg Knight in several countries, including the UK, where the estate model was sold as the Tourist. It remained on sale until 1976, by which time nearly 20,000 had been sold. This marked the end of right-hand drive Wartburgs, but left-hand drive versions continued to be imported to the UK and at least one model was converted to right-hand drive. Also, in 1966, the gearbox gained synchromesh on all speeds and was designed to freewheel as a fuel efficiency and engine protection measure, which meant that unless the freewheel feature was disabled by a lever beneath the steering column, the car did not benefit from engine braking. Because the engine was a two stroke unit, it relied on the passage of the petrol mixture (two-stroke oil and petrol, at a ratio of 1:50) to lubricate the engine. With the freewheel device disengaged, the engine could be starved of lubricant and seize on long down-hill runs unless the throttle was opened briefly from time to time. Nevertheless, disengaging the freewheel device was recommended to give engine braking in snowy or icy conditions. There are four editions of Wartburg 353: There are three models of Wartburg 353 - Limousine (sedan), Tourist (combi) and Trans (pickup). The 353W modification had a new, round-shaped dashboard and black-coloured grille. It was also fitted with disc brakes on the front axle. The 353S modification featured new rectangular headlights integrated into the grille of a new shape. In the De Luxe version you can see electronic ignition, 5-speed gearbox, front and back fog lights, alarm system and central lock door. Usually this model can reach around 150-155 km/h.

Through this friendship, Tieck was given a first-hand look at the poor, which could be linked to his work as a Romanticist. He later attended the universities of Halle, Göttingen, and Erlangen. At Göttingen, he studied Shakespeare and Elizabethan drama. On returning to Berlin in 1794, Tieck attempted to make a living by writing. He contributed a number of short stories (1795–98) to the series \"Straussfedern\", published by the bookseller C. F. Nicolai and originally edited by J. K. A. Musäus. He also wrote \"Abdallah\" (1796) and a novel in letters, \"William Lovell\" (3 vols, 1795–96).", "section_level": 1}, {"title": "Adoption of Romanticism.", "content": "Tieck's transition to Romanticism is seen in the series of plays and stories published under the title \"Volksmärchen von Peter Lebrecht\" (3 vols., 1797), a collection containing the fairy tale \"Der blonde Eckbert\", which blends exploration of the paranoiac mind with the realm of the supernatural, and a witty dramatic satire on Berlin literary taste, \"Der gestiefelte Kater\". With his school and college friend Wilhelm Heinrich Wackenroder (1773–1798), he planned the novel \"Franz Sternbalds Wanderungen\" (vols. i–ii. 1798), which with Wackenroder's \"Herzensergiessungen\" (1796), was the first expression of the Romantic enthusiasm for old German art. In 1798 Tieck married and in the following year settled in Jena, where he, the two brothers August and Friedrich Schlegel, and Novalis were the leaders of the early Romantic school (also known as Jena Romanticism). His writings between 1798 and 1804 include the satirical drama, \"Prinz Zerbino\" (1799), and \"Romantische Dichtungen\" (2 vols., 1799–1800). The latter contains Tieck's most ambitious dramatic poems, \"Leben und Tod der heiligen Genoveva\", \"Leben und Tod des kleinen Rotkäppchens\", which were followed in 1804 by the \"comedy\" in two parts, \"Kaiser Oktavianus\". These dramas are typical plays of the first Romantic school. Although formless and destitute of dramatic qualities, they show the influence of both Calderón and Shakespeare. \"Kaiser Oktavianus\" is a poetic glorification of the Middle Ages. In 1801 Tieck went to Dresden, then lived for a time at Ziebingen near Frankfurt, and spent many months in Italy. In 1803 he published a translation of \"Minnelieder aus der schwäbischen Vorzeit\", then between 1799 and 1804 an excellent version of \"Don Quixote\", and in 1811 two volumes of Elizabethan dramas, \"Altenglisches Theater\". From 1812 to 1817 he collected in three volumes a number of his earlier stories and dramas, under the title \"Phantasus\". In this collection appeared the stories \"Der Runenberg\", \"Die Elfen\", \"Der Pokal\", and the dramatic fairy tale \"Fortunat\". In 1817 Tieck visited England in order to collect materials for a work on Shakespeare, which was never finished. In 1819 he settled permanently in Dresden, and from 1825 he was literary adviser to the Court Theatre. His semi-public readings from the dramatic poets gave him a reputation which extended far beyond the capital of the Kingdom of Saxony. The new series of short stories which he began to publish in 1822 also won him a wide popularity. Notable among these are \"Die Gemälde\", \"Die Reisenden\", \"Die Verlobung\", and \"Des Lebens Überfluss\".

Afterwards, Brehm travelled to Africa as well as to Scandinavia and Siberia. His essays and expedition reports from the animal world were well received by the educated bourgeoisie; because of this, he was commissioned by the editor of the Bibliographisches Institut, Herrmann Julius Meyer, to write a large multivolume work on the animal world. This book became known worldwide as \"Brehms Tierleben\" (or, in English, \"Brehm's Life of Animals\").

Until that time the monks of Europe worked at their trade in their monastery. Renouncing personal property, they owned all things in common as a community after the example of chapters 2 and 4 of the Acts of the Apostles. With the rise of Western monasticism, monasteries attracted not only individuals aspiring to become monks and nuns, but also property, buildings and hence riches. In the view of some, the idea that Christ came down to earth poor and that the true Church must be the church of the poor clashed with this phenomenon. The desire for true Christian authenticity was thus seen by some to contrast to the empirical reality of the Church. The twelfth century saw great changes in western Europe. As commerce revived, urban centers arose and with them an urban middle class. New directions in spirituality were called for. Church reform became a major theme of the cultural revival of this era. In response to this, there emerged the new mendicant orders founded by Francis of Assisi (c. 1181–1226) and Dominic Guzman (c. 1170–1221). The mendicant friars were bound by a vow of poverty and dedicated to an ascetic way of life, renouncing property and travelling the world to preach. Their survival was dependent upon the good will and material support of their listeners. It was this way of life that gave them their name, \"mendicant\", derived from the Latin \"mendicare\", meaning \"to beg\". The mendicant movement had started in France and Italy and became popular in the poorer towns and cities of Europe at the beginning of the thirteenth century. The refusal of the mendicants to own property—and therefore to pay taxes—was seen as threatening the stability of the established Church which was then planning a crusade, to be financed by tithes. For this and other reasons some mendicant orders were officially suppressed by Pope Gregory X at the Second Council of Lyon in 1274 and others were reformed, so as to be capable of contributing funds or men to support the war effort.", "section_level": 1}, {"title": "Dominicans.", "content": "While on a visit to southern France, Saint Dominic met the Albigensians, a religious sect which had a great popularity partly because of the economic situation of the times.

Before this time, religious life had been monastic, but with Dominic the secluded monastery gave way to priories in the cities.

The emergence of urban centers meant concentrated numbers of the homeless and the sick. This created problems for the parish churches who found themselves unable to address these issues. Since many people were moving from the countryside to the cities, they no longer built their convents in rural districts but rather in urban zones. In another innovation, the mendicant orders relinquished their principle of stability, a classical principle of ancient monasticism, opting for a different approach. Unlike the Benedictine monks, the mendicants were not permanently attached to any one particular convent and to its abbot. Because the orders' primary aim was the evangelization of the masses, the church granted them freedom from the jurisdiction of the bishops and they traveled about to convert or reinforce faith. The freedom of mendicancy allowed Franciscans and Dominicans mobility. Since they were not tied to monasteries or territorial parishes, they were free to take the gospel into the streets, to preach, hear confessions and minister to people wherever they were. Friars Minor and Preachers traveled with missionary zeal from one place to another. Consequently, they organized themselves differently in comparison with the majority of monastic orders. Instead of the traditional autonomy that every monastery enjoyed, they gave greater importance to the order as such and to the Superior General, as well as to the structure of the order Provinces. Their flexibility enabled them to send out the most suitable friars on specific missions, and the mendicant orders reached North Africa, the Middle East and Northern Europe. As students and professors, Friars Minor and Friars Preacher, Franciscans and Dominicans, entered the leading universities of the time, set up study centers, produced texts of great value and were protagonists of scholastic theology in its best period and had an important effect on the development of thought. The great thinkers, St Thomas Aquinas and St Bonaventure, were mendicants. In all the great cities of western Europe, friaries were established, and in the universities theological chairs were held by Dominicans and Franciscans. Later in the 13th century they were joined by the mendicant orders of Carmelites, Augustinian Hermits, and Servites. They attracted a significant level of patronage, as much from townsfolk as aristocrats. Their focus of operation rapidly centered on towns where population growth historically outstripped the provision of rural parishes.

In 1809, he went to Berlin, where he became a teacher at the Gymnasium zum Grauen Kloster and at the Plamann School. Brooding upon what he saw as the humiliation of his native land by Napoleon, Jahn conceived the idea of restoring the spirits of his countrymen by the development of their physical and moral powers through the practice of gymnastics. The first \"Turnplatz\", or open-air gymnasium, was opened by Jahn in Berlin in 1811, and the \"Turnverein\" (gymnastics association) movement spread rapidly. Young gymnasts were taught to regard themselves as members of a kind of guild for the emancipation of their fatherland. The nationalistic spirit was nourished in a significant degree by the writings of Jahn. In the Early 1813 Jahn took an active part in the formation of the famous Lützow Free Corps, a volunteer force in the Prussian army fighting Napoleon. He commanded a battalion of the corps, but he was often employed in the secret service during the same period. After the war, he returned to Berlin, where he was appointed state teacher of gymnastics, and he took on a role in the formation of the student patriotic fraternities, or Burschenschaften, in Jena. A man of populistic nature, rugged, eccentric and outspoken, Jahn often came into conflict with the authorities. The authorities finally realized he aimed at establishing a united Germany and that his \"Turner\" schools were political and liberal clubs. The conflict resulted in the closing of the \"Turnplatz\" in 1819 and Jahn's arrest. Kept in semi-confinement successively at Spandau, Küstrin, and at the fortress in Kolberg until 1824, he was sentenced to imprisonment for two years. The sentence was reversed in 1825, but he was forbidden to live within ten miles of Berlin. He therefore took up residence at Freyburg on the Unstrut, where he remained until his death, with the exception of a short period in 1828, when he was exiled to Kölleda on a charge of sedition. While at Freyburg, he received an invitation to become professor of German literature at Cambridge, Massachusetts, which he declined, saying that “deer and hares love to live where they are most hunted.” In 1840, Jahn was decorated by the Prussian government with the Iron Cross for bravery in the wars against Napoleon. In the spring of 1848, he was elected by the district of Naumburg to the German National Parliament. Jahn died in Freyburg, where a monument was erected in his honor in 1859.

He advocated that the German states should unite after the withdrawal of Napoleon's occupying armies, and establish a democratic constitution (under the Hohenzollern monarchy), which would include the right to free speech. As a German nationalist, Jahn advocated maintaining German language and culture against foreign influence. In 1810 he wrote, \"Poles, French, priests, aristocrats and Jews are Germany's misfortune.\" At the time Jahn wrote this, the German states were occupied by foreign armies under the leadership of Napoleon. Also, Jahn was \"the guiding spirit\" of the fanatic book burning episode carried out by revolutionary students at the Wartburg festival in 1817. Jahn gained infamy in English-speaking countries through the publication of Peter Viereck's \"Metapolitics: The Roots of the Nazi Mind\" (1941). Viereck claimed Jahn as the spiritual founder of Nazism, who inspired the early German romantics with anti-Semitic and authoritarian doctrines, and then influenced Wagner and finally the Nazis. However, Jacques Barzun observed that Viereck's portrait of cultural trends supposedly leading to Nazism was \"a caricature without resemblance\" relying on \"misleading shortcuts\". Scholarly focus on the völkischness of Jahn's thought started in the 1920s with a new generation of Jahn interpreters like Edmund Neuendorff and Karl Müller. Neuendorff explicitly linked Jahn with National Socialism. The equation by the National Socialists of Jahn's ideas with their world view was more or less complete by the mid-1930s. Alfred Baeumler, an educational philosopher and university lecturer who attempted to provide theoretical support for Nazi ideology (through the interpretation of Nietzsche among others) wrote a monograph on Jahn in which he characterises Jahn's invention of gymnastics as an explicitly political project, designed to create the ultimate völkisch citizen by educating his body.", "section_level": 1}], "src_summary": "Friedrich Ludwig Jahn (11 August 1778 – 15 October 1852) was a German gymnastics educator and nationalist whose writing is credited with the founding of the German gymnastics (Turner) movement as well as influencing the German Campaign of 1813, during which a coalition of German states effectively ended the occupation of Napoleon's First French Empire.

For example, carbon dioxide gas dissolves in water to produce a solution that contains hydronium, carbonate, and hydrogen carbonate ions. Molten salts can also be electrolytes as, for example, when sodium chloride is molten, the liquid conducts electricity. In particular, ionic liquids, which are molten salts with melting points below 100 °C, are a type of highly conductive non-aqueous electrolytes and thus have found more and more applications in fuel cells and batteries. An electrolyte in a solution may be described as \"concentrated\" if it has a high concentration of ions, or \"diluted\" if it has a low concentration. If a high proportion of the solute dissociates to form free ions, the electrolyte is strong; if most of the solute does not dissociate, the electrolyte is weak. The properties of electrolytes may be exploited using electrolysis to extract constituent elements and compounds contained within the solution. Alkaline earth metals form hydroxides that are strong electrolytes with limited solubility in water, due to the strong attraction between their constituent ions. This limits their application to situations where high solubility is required.", "section_level": 1}, {"title": "Physiological importance.", "content": "In physiology, the primary ions of electrolytes are sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), chloride (Cl), hydrogen phosphate (HPO), and hydrogen carbonate (HCO). The electric charge symbols of plus (+) and minus (−) indicate that the substance is ionic in nature and has an imbalanced distribution of electrons, the result of chemical dissociation. Sodium is the main electrolyte found in extracellular fluid and potassium is the main intracellular electrolyte; both are involved in fluid balance and blood pressure control. All known multicellular lifeforms require a subtle and complex electrolyte balance between the intracellular and extracellular environments. In particular, the maintenance of precise osmotic gradients of electrolytes is important. Such gradients affect and regulate the hydration of the body as well as blood pH, and are critical for nerve and muscle function. Various mechanisms exist in living species that keep the concentrations of different electrolytes under tight control. Both muscle tissue and neurons are considered electric tissues of the body. Muscles and neurons are activated by electrolyte activity between the extracellular fluid or interstitial fluid, and intracellular fluid. Electrolytes may enter or leave the cell membrane through specialized protein structures embedded in the plasma membrane called \"ion channels\". For example, muscle contraction is dependent upon the presence of calcium (Ca), sodium (Na), and potassium (K). Without sufficient levels of these key electrolytes, muscle weakness or severe muscle contractions may occur. Electrolyte balance is maintained by oral, or in emergencies, intravenous (IV) intake of electrolyte-containing substances, and is regulated by hormones, in general with the kidneys flushing out excess levels. In humans, electrolyte homeostasis is regulated by hormones such as antidiuretic hormones, aldosterone and parathyroid hormones.

Lone electrons normally cannot pass through the electrolyte; instead, a chemical reaction occurs at the cathode, providing electrons to the electrolyte. Another reaction occurs at the anode, consuming electrons from the electrolyte. As a result, a negative charge cloud develops in the electrolyte around the cathode, and a positive charge develops around the anode. The ions in the electrolyte neutralize these charges, enabling the electrons to keep flowing and the reactions to continue. For example, in a solution of ordinary table salt (sodium chloride, NaCl) in water, the cathode reaction will be and hydrogen gas will bubble up; the anode reaction is and chlorine gas will be liberated. The positively charged sodium ions Na will react toward the cathode, neutralizing the negative charge of OH there, and the negatively charged hydroxide ions OH will react toward the anode, neutralizing the positive charge of Na there. Without the ions from the electrolyte, the charges around the electrode would slow down continued electron flow; diffusion of H and OH through water to the other electrode takes longer than movement of the much more prevalent salt ions. Electrolytes dissociate in water because water molecules are dipoles and the dipoles orient in an energetically favorable manner to solvate the ions.

Digitally generated cards allow vendors, viewers and television stations to adjust their equipment for optimal functionality. The audio broadcast while test cards are shown is typically a sine wave tone, radio (if associated or affiliated with the television channel) or music (usually instrumental, though some also broadcast with jazz or popular music).

He studied medicine but also had time for literary pursuits in the company of Ludwig Uhland, Gustav Schwab and others. He took his doctor's degree in 1808, spent some time travelling, and then settled as a practising physician in Wildbad. Here he completed his \"Reiseschatten von dem Schattenspieler Luchs\" (1811), in which his own experiences are described with caustic humour.

Aitmatov lived at a time when Kyrgyzstan was being transformed from one of the most remote lands of the Russian Empire to a republic of the USSR. The future author studied at a Soviet school in Sheker. He also worked from an early age. At fourteen, he was an assistant to the Secretary at the Village Soviet. He later held jobs as a tax collector, a loader, an engineer's assistant and continued with many other types of work. In 1946, he began studying at the Animal Husbandry Division of the Kirghiz Agricultural Institute in Frunze, but later switched to literary studies at the Maxim Gorky Literature Institute in Moscow, where he lived from 1956-58. For the next eight years he worked for Pravda. His first two publications appeared in 1952 in Russian: \"The Newspaper Boy Dziuio\" and \"Ашым.\" His first work published in Kyrgyz was \"Ак Жаан\" (White rain, 1954), and his well-known work \"Jamila\" (Jamila) appeared in 1958. In 1961, he was a member of the jury at the 2nd Moscow International Film Festival.

Aitmatov's art was glorified by admirers. Even critics of Aitmatov mentioned the high quality of his novels. Aitmatov's work has some elements that are unique specifically to his creative process. His work drew on folklore, not in the ancient sense of it; rather, he tried to recreate and synthesize oral tales in the context of contemporary life. This is prevalent in his work; in nearly every story he refers to a myth, a legend, or a folktale. In \"The Day Lasts More Than a Hundred Years,\" a poetic legend about a young captive turned into a mankurt serves as a tragic allegory and becomes a significant symbolic expression of the philosophy of the novel. His work also touches on Kyrgyzstan’s transformation from the Russian empire to a republic of the USSR and the lives of its people during the transformation. This is prevalent in one of his work in \"Farewell, Gyusalry!\" Although the short story touches on the idea of friendship and loyalty between a man and his stallion, it also serves an tragic allegory of the political and USSR government. It explores the loss and grief that many Kyrgyz faced through the protagonist character in the short story. A second aspect of Aitmatov's writing is his ultimate closeness to our \"little brothers\" the animals, for their and our lives are intimately and inseparably connected. The two central characters of \"Farewell, Gulsary!\" are a man and his stallion. A camel plays a prominent role in \"The Day Lasts More Than a Hundred Years\"; one of the key turns of the novel which decides the fate of the main character is narrated through the story of the camel's rut and riot. \"The Scaffold\" starts off and finishes with the story of a wolf pack and the great wolf-mother Akbara and her cub; human lives enter the narrative but interweave with the lives of the wolves. Some of his stories were filmed, like \"The First Teacher\" in 1965 and \"Red Scarf\" (1970) as \"The Girl with the Red Scarf\" (1978). As many educated Kyrgyzs, Aitmatov was fluent in both Kyrgyz and Russian. As he explained in one of his interviews, Russian was as much of a native language for him as Kyrgyz.

His name appears in several forms, one of the most common being \"Ludolf Karl Adelbert von Chamisso.\" In 1790, the French Revolution drove his parents out of France with their seven children, and they went successively to Liège, the Hague, Würzburg, and Bayreuth, and possibly Hamburg where he reportedly met both a younger boy in Johann August Wilhelm Neander and another younger boy in Karl August Varnhagen von Ense before settling in Berlin. There, in 1796 the young Chamisso was fortunate in obtaining the post of page-in-waiting to the queen of Prussia, and in 1798 he entered a Prussian infantry regiment as an ensign to train for a career as an army officer. Shortly thereafter, thanks to the Peace of Tilsit, his family was able to return to France, but Chamisso remained in Prussia and continued his military career. He had little formal education, but while in the Prussian military service in Berlin he assiduously studied natural science for three years. In collaboration with Varnhagen von Ense, in 1803 he founded the \"Berliner Musenalmanach\", the publication in which his first verses appeared. The enterprise was a failure, and, interrupted by the Napoleonic wars, it came to an end in 1806. It brought him, however, to the notice of many of the literary celebrities of the day and established his reputation as a rising poet. Chamisso had become a lieutenant in 1801, and in 1805 he accompanied his regiment to Hamelin, where he shared in the humiliation of the town's treasonable capitulation the next year. Placed on parole, he went to France, but both his parents were dead; returning to Berlin in the autumn of 1807, he obtained his release from the Prussian service early the following year. Homeless and without a profession, disillusioned and despondent, Chamisso lived in Berlin until 1810, when through the services of an old friend of the family he was offered a professorship at the \"lycée\" at Napoléonville in the Vendée. He set out to take up the post, but instead joined the circle of Madame de Staël, and followed her in her exile to Coppet in Switzerland, where, devoting himself to botanical research, he remained nearly two years. In 1812 he returned to Berlin, where he continued his scientific studies. In the summer of the eventful year, 1813, he wrote the prose narrative \"Peter Schlemihl\", the man who sold his shadow. This, the most famous of all his works, has been translated into most European languages (English by William Howitt). It was written partly to divert his own thoughts and partly to amuse the children of his friend Julius Eduard Hitzig. In 1815, Chamisso was appointed botanist to the Russian ship \"Rurik\", fitted out at the expense of Count Nikolay Rumyantsev, which Otto von Kotzebue (son of August von Kotzebue) commanded on a scientific voyage round the world. He collected at the Cape of Good Hope in January 1818 in the company of Krebs, Mund and Maire. His diary of the expedition (\"Tagebuch\", 1821) is a fascinating account of the expedition to the Pacific Ocean and the Bering Sea. During this trip Chamisso described a number of new species found in what is now the San Francisco Bay Area. Several of these, including the California poppy, \"Eschscholzia californica\", were named after his friend Johann Friedrich von Eschscholtz, the Rurik's entomologist. In return, Eschscholtz named a variety of plants, including the genus \"Camissonia\", after Chamisso. On his return in 1818 he was made custodian of the botanical gardens in Berlin, and was elected a member of the Academy of Sciences, and in 1819 he married his friend Hitzig's foster daughter Antonie Piaste (1800–1837). He became a leading member of the Serapion Brethren, a literary circle around E. T. A. Hoffmann. In 1827, partly for the purpose of rebutting the charges brought against him by Kotzebue, he published \"Views and Remarks on a Voyage of Discovery\", and \"Description of a Voyage Round the World\". Both works display great accuracy and industry. His last scientific labor was a tract on the Hawaiian language. Chamisso's travels and scientific researches restrained for a while the full development of his poetical talent, and it was not until his forty-eighth year that he turned back to literature. In 1829, in collaboration with Gustav Schwab, and from 1832 in conjunction with Franz von Gaudy, he brought out the \"Deutscher Musenalmanach\", in which his later poems were mainly published. Chamisso died in Berlin at the age of 57.

A \"local exploit\" requires prior access to the vulnerable system and usually increases the privileges of the person running the exploit past those granted by the system administrator. Exploits against client applications also exist, usually consisting of modified servers that send an exploit if accessed with a client application. Exploits against client applications may also require some interaction with the user and thus may be used in combination with the social engineering method. Another classification is by the action against the vulnerable system; unauthorized data access, arbitrary code execution, and denial of service are examples. Many exploits are designed to provide superuser-level access to a computer system. However, it is also possible to use several exploits, first to gain low-level access, then to escalate privileges repeatedly until one reaches the highest administrative level (often called \"root\"). After an exploit is made known to the authors of the affected software, the vulnerability is often fixed through a patch and the exploit becomes unusable.

These types of attacks are often called multi-layered attacks. Pivoting is also known as \"island hopping\". Pivoting can further be distinguished into proxy pivoting and VPN pivoting. Proxy pivoting generally describes the practice of channeling traffic through a compromised target using a proxy payload on the machine and launching attacks from the computer. This type of pivoting is restricted to certain TCP and UDP ports that are supported by the proxy. VPN pivoting enables the attacker to create an encrypted layer to tunnel into the compromised machine to route any network traffic through that target machine, for example, to run a vulnerability scan on the internal network through the compromised machine, effectively giving the attacker full network access as if they were behind the firewall. Typically, the proxy or VPN applications enabling pivoting are executed on the target computer as the payload (software) of an exploit. Pivoting is usually done by infiltrating a part of a network infrastructure (as an example, a vulnerable printer or thermostat) and using a scanner to find other devices connected to attack them.

The Italian \"machiavellista\" and \"machiavello\" also go back to the 16th century. The Oxford English Dictionary defines \"Machiavellian\" (as an adjective) as: \"Of, pertaining to, or characteristic of Machiavelli, or his alleged principles; following the methods recommended by Machiavelli in preferring expediency to morality; practicing duplicity in statecraft or in general conduct; astute, cunning, intriguing\".

Machiavelli's view that acquiring a state and maintaining it requires evil means has been noted as the chief theme of the treatise. In the late 1530s, immediately following the publication of \"The Prince\", Machiavelli's philosophy was seen as an immoral ideology that corrupted European politics. Reginald Pole read the treatise while he was in Italy, and on which he commented: \"I found this type of book to be written by an enemy of the human race. It explains every means whereby religion, justice and any inclination toward virtue could be destroyed\". Due to the treatise's controversial analysis on politics, in 1559, the Catholic Church banned \"The Prince\", putting it on the \"Index Librorum Prohibitorum\". Machiavelli's works were received similarly by other popular European authors, especially in Protestant Elizabethan England. The \"Anti-Machiavel\" is an 18th-century essay by Frederick the Great, King of Prussia and patron of Voltaire, rebutting \"The Prince\". It was first published in September 1740, a few months after Frederick became king.

The massacre \"spawned a pullulating mass of polemical literature, bubbling with theories, prejudices and phobias\", in which Machiavellianism featured prominently. This view was greatly influenced by the Huguenot lawyer, who published his \"Discours contre Machievel\" in 1576, which was printed in ten editions in three languages over the next four years. Gentillet held, quite wrongly according to Sydney Anglo, that Machiavelli's \"books [were] held most dear and precious by our Italian and Italionized courtiers\" (in the words of his first English translation, \"Anti-Machiavel: A Discourse Upon the Means of Well Governing\"), and so (in Anglo's paraphrase) \"at the root of France's present degradation, which has culminated not only in the St Bartholomew massacre but the glee of its perverted admirers\". In fact there is little trace of Machiavelli in French writings before the massacre, and not very much after, until Gentillet's own book, but this concept was seized upon by many contemporaries, and played a crucial part in setting the long-lasting popular concept of Machiavellianism. It also gave added impetus to the strong anti-Italian feelings already present in Huguenot polemic. The Catholic Encyclopedia of 1913 was still ready to endorse a version of this view, describing the massacres as \"an entirely political act committed in the name of the immoral principles of Machiavellianism\" and blaming \"the pagan theories of a certain raison d'état according to which the end justified the means\".", "section_level": 1}, {"title": "English drama.", "content": "Christopher Marlowe was one of many Elizabethan English writers who were enthusiastic promoters of the trope, and although Machiavelli had not yet been published in English, he evidently expects his theatrical audience to understand the references.

Sitka spruce is used widely in piano, harp, violin, and guitar manufacture, as its high strength-to-weight ratio and regular, knot-free rings make it an excellent conductor of sound. For these reasons, the wood is also an important material for sailboat spars, and aircraft wing spars (including flying models). The Wright brothers' Flyer was built using Sitka spruce, as were many aircraft before World War II; during that war, aircraft such as the British Mosquito used it as a substitute for strategically important aluminium.

Many globes are made with a circumference of one metre, so they are models of the Earth at a scale of 1:40 million. In imperial units, many globes are made with a diameter of one foot (about 30 cm), yielding a circumference of 3.14 feet (about 96 cm) and a scale of 1:42 million.

No terrestrial globes from Antiquity or the Middle Ages have survived. An example of a surviving celestial globe is part of a Hellenistic sculpture, called the Farnese Atlas, surviving in a 2nd-century AD Roman copy in the Naples Archaeological Museum, Italy. Early terrestrial globes depicting the entirety of the Old World were constructed in the Islamic world. According to David Woodward, one such example was the terrestrial globe introduced to Beijing by the Persian astronomer, Jamal ad-Din, in 1267. The earliest extant terrestrial globe was made in 1492 by Martin Behaim (1459–1537) with help from the painter Georg Glockendon. Behaim was a German mapmaker, navigator, and merchant. Working in Nuremberg, Germany, he called his globe the \"Nürnberg Terrestrial Globe.\" It is now known as the Erdapfel. Before constructing the globe, Behaim had traveled extensively. He sojourned in Lisbon from 1480, developing commercial interests and mingling with explorers and scientists. In 1485–1486, he sailed with Portuguese explorer Diogo Cão to the coast of West Africa. He began to construct his globe after his return to Nürnberg in 1490. Another early globe, the Hunt–Lenox Globe, ca. 1510, is thought to be the source of the phrase \"Hic Sunt Dracones\", or “Here be dragons”. A similar grapefruit-sized globe made from two halves of an ostrich egg was found in 2012 and is believed to date from 1504. It may be the oldest globe to show the New World. Stefaan Missine, who analyzed the globe for the Washington Map Society journal \"Portolan\", said it was “part of an important European collection for decades.” After a year of research in which he consulted many experts, Missine concluded the Hunt–Lenox Globe was a copper cast of the egg globe. A facsimile globe showing America was made by Martin Waldseemueller in 1507. Another \"remarkably modern-looking\" terrestrial globe of the Earth was constructed by Taqi al-Din at the Constantinople Observatory of Taqi ad-Din during the 1570s. The world's first seamless celestial globe was built by Mughal scientists under the patronage of Jahangir. \"Globus\" IMP, electro-mechanical devices including five-inch globes have been used in Soviet and Russian spacecraft from 1961 to 2002 as navigation instruments.

This method of globe making was illustrated in 1802 in an engraving in The English Encyclopedia by George Kearsley. Modern globes are often made from thermoplastic. Flat, plastic disks are printed with a distorted map of one of the Earth's Hemispheres. This is placed in a machine which molds the disk into a hemispherical shape. The hemisphere is united with its opposite counterpart to form a complete globe.

The Z1 was wholly mechanical and only worked for a few minutes at a time at most. Helmut Schreyer advised Zuse to use a different technology. As a doctoral student at the Berlin Institute of Technology in 1937 he worked on the implementation of Boolean operations and (in today's terminology) flip-flops on the basis of vacuum tubes. In 1938 Schreyer demonstrated a circuit on this basis to a small audience, and explained his vision of an electronic computing machine – but since the largest operational electronic devices contained far fewer tubes this was considered practically infeasible. In that year when presenting the plan for a computer with 2,000 electron tubes, Zuse and Schreyer, who was an assistant at Prof. Wilhelm Stäblein's Telecommunication Institute at the Technical University of Berlin, were discouraged by members of the institute who knew about the problems with electron tube technology. Zuse later recalled: “They smiled at us in 1939, when we wanted to build electronic machines... We said: The electronic machine is great, but first the components have to be developed.\" In 1940 Zuse and Schreyer managed to arrange a meeting at the Oberkommando der Wehrmacht (OKW) to discuss a potential project for developing an electronic computer, but when they estimated a duration of two or three years, the proposal was rejected. Zuse decided to implement the next design based on relays. The realization of the Z2 was helped financially by Dr. Kurt Pannke, who manufactured small calculating machines. The Z2 was completed and presented to an audience of the (\"German Laboratory for Aviation\") in 1940 in Berlin-Adlershof. Zuse was lucky – this presentation was one of the few instances where the Z2 actually worked and could convince the DVL to partly finance the next design. Improving on the basic Z2 machine, he built the Z3 in 1941, which was a highly secret project of the German government. Dr. Joseph Jennissen (1905–1977), member of the \"Research-Leadership\" (\"Forschungsführung\") in the Reich Air Ministry acted as a government supervisor for orders of the ministry to Zuse's company \"ZUSE Apparatebau\". A further intermediary between Zuse and the Reich Air Ministry was the aerodynamicist Herbert A. Wagner. The Z3 was completed in 1941 and was faster and far more reliable than the Z1 and Z2. The Z3 floating-point arithmetic was improved over that of the Z1 in that it implemented exception handling \"using just a few relays\", the exceptional values (plus infinity, minus infinity and undefined) could be generated and passed through operations. The Z3 stored its program on an external tape, thus no rewiring was necessary to change programs. On 12 May 1941 the Z3 was presented to an audience of scientists including the professors Alfred Teichmann and Curt Schmieden of the (\"German Laboratory for Aviation\") in Berlin, today known as the German Aerospace Center in Cologne.

Nevertheless, the Z3 was Turing-complete – how to implement a universal Turing machine on the Z3 was shown in 1998 by Raúl Rojas. He proposed that the tape program would have to be long enough to execute every possible path through both sides of every branch. It would compute all possible answers, but the unneeded results would be canceled out (a kind of speculative execution). Rojas concludes, \"We can therefore say that, from an abstract theoretical perspective, the computing model of the Z3 is equivalent to the computing model of today's computers. From a practical perspective, and in the way the Z3 was really programmed, it was not equivalent to modern computers.\" From a pragmatic point of view, however, the Z3 provided a quite \"practical\" instruction set for the typical engineering applications of the 1940s – Zuse was a civil engineer who only started to build his computers to facilitate his work in his main profession.", "section_level": 1}, {"title": "Relation to other work.", "content": "The success of Zuse's Z3 is often attributed to its use of the simple binary system. This was invented roughly three centuries earlier by Gottfried Leibniz; Boole later used it to develop his Boolean algebra. Zuse was inspired by Hilbert's and Ackermann's book on elementary mathematical logic (cf. Principles of Mathematical Logic). In 1937, Claude Shannon introduced the idea of mapping Boolean algebra onto electronic relays in a seminal work on digital circuit design. Zuse, however, did not know Shannon's work and developed the groundwork independently for his first computer Z1, which he designed and built from 1935 to 1938. Zuse's coworker Helmut Schreyer built an electronic digital experimental model of a computer using 100 vacuum tubes in 1942, but it was lost at the end of the war. An analog computer was built by the rocket scientist Helmut Hölzer in 1942 at the Peenemünde Army Research Center to simulate V-2 rocket trajectories. The Tommy Flowers-built Colossus (1943) and the Atanasoff–Berry Computer (1942) used thermionic valves (vacuum tubes) and binary representation of numbers. Programming was by means of re-plugging patch panels and setting switches. The ENIAC computer, completed after the war, used vacuum tubes to implement switches and used decimal representation for numbers. Until 1948 programming was, as with Colossus, by patch leads and switches. The Manchester Baby of 1948 along with the Manchester Mark 1 and EDSAC both of 1949 were the world's earliest working computers that stored program instructions and data in the same space. In this they implemented the stored-program concept which is frequently (but erroneously) attributed to a 1945 paper by John von Neumann and colleagues. Von Neumann is said to have given due credit to Alan Turing, and the concept had actually been mentioned earlier by Konrad Zuse himself, in a 1936 patent application (that was rejected). Konrad Zuse himself remembered in his memoirs: \"During the war it would have barely been possible to build efficient stored program devices anyway.\" and Friedrich L.

The increased size may be countered by lower-level link compression, as the resulting text data will have about as much less entropy as it has increased size, so the actual data transferred in this scenario would likely be very close to the size of the original binary data. See Binary-to-text encoding for more on this subject. Microsoft Windows and its standard libraries for the C and C++ programming languages allow the programmer to specify a parameter indicating if a file is expected to be plain text or binary when opening a file; this affects the standard library calls to read and write from the file in that the system converts between the C/C++ \"end of line\" character (the ASCII linefeed character) and the end-of-line sequence Windows expects in files (the ASCII carriage return and linefeed characters in sequence). In Unix-like systems, the C and C++ standard libraries on those systems also allow the programmer to specify whether a file is expected to be text or binary, but the libraries can and do ignore that parameter, as the end-of-line sequence in Unix-like systems is just the C/C++ end-of-line character.", "section_level": 1}, {"title": "Viewing.", "content": "A hex editor or viewer may be used to view file data as a sequence of hexadecimal (or decimal, binary or ASCII character) values for corresponding bytes of a binary file.

Other type of viewers (called 'word extractors') simply replace the unprintable characters with spaces revealing only the human-readable text. This type of view is useful for quick inspection of a binary file in order to find passwords in games, find hidden text in non-text files and recover corrupted documents. It can even be used to inspect suspicious files (software) for unwanted effects. For example, the user would see any URL/email to which the suspected software may attempt to connect in order to upload unapproved data (to steal).

During the 4th century, the Burgundians, a Germanic people, who may have originated in Bornholm (on the Baltic Sea), settled in the western Alps. They founded the Kingdom of the Burgundians, which was conquered in the 6th century by another Germanic tribe, the Franks. Under Frankish dominion, the Kingdom of Burgundy continued for several centuries. Later, the region was divided between the Duchy of Burgundy (to the west) and the Free County of Burgundy (to the east). The Duchy of Burgundy is the better-known of the two, later becoming the French province of Burgundy, while the County of Burgundy became the French province of Franche-Comté, literally meaning \"free county\". Burgundy's modern existence is rooted in the dissolution of the Frankish Empire. In the 880s, there were four Burgundies: the duchy, the county, and the kingdoms of Upper Burgundy and Lower Burgundy. During the Middle Ages, Burgundy was home to some of the most important Western churches and monasteries, including those of Cluny, Cîteaux, and Vézelay. Cluny, founded in 910, exerted a strong influence in Europe for centuries. The first Cistercian abbey was founded in 1098 in Cîteaux. Over the next century, hundreds of Cistercian abbeys were founded throughout Europe, in a large part due to the charisma and influence of Bernard of Clairvaux. The Abbey of Fontenay, a UNESCO World Heritage site, is today the best-preserved Cistercian abbey in Burgundy. The Abbey of Vezelay, also a UNESCO site, is still a starting point for pilgrimages to Santiago de Compostela. Cluny was almost totally destroyed during the French Revolution. During the Hundred Years' War, King John II of France gave the duchy to his youngest son, Philip the Bold. The duchy soon became a major rival to the crown. The court in Dijon outshone the French court both economically and culturally. In 1477, at the battle of Nancy during the Burgundian Wars, the last duke Charles the Bold was killed in battle, and the Duchy itself was annexed by France and became a province. However the northern part of the empire was taken by the Austrian Habsburgs.

The area belonged to the Czech (Bohemian) Duchy (and later Kingdom) since the 11th century. It was first mentioned under the Latinized name \"Sitavia\" in 1238. It was granted town rights in 1255 by King Ottokar II of Bohemia, who also built defensive walls. In 1319 it passed to the Piast-ruled Duchy of Jawor of then-fragmented Poland, and after the death of Duke Henry I of Jawor in 1346, it became part of the Czech (Bohemian) Crown again. The city's coat of arms still shows a Czech Lion and a Silesian Piast Eagle. In 1346 the city became one of the members of the Six-City League of Upper Lusatia. At that time the city was granted a special title—it was called \"Die Reiche\" (\"the Rich\") because of its high proportion of well-to-do citizens. In 1359 and 1422 it suffered great fires. In 1469, together with the Lusatian League, the city recognized Hungarian King Matthias Corvinus as rightful ruler, thus passing to Hungary, and after his death in 1490 the city returned to the Bohemian Crown, then under the rule of Polish prince Vladislaus II. It remained part of it until 1635 when it passed to the Electorate of Saxony. During the Counter-Reformation, especially following the Battle of White Mountain in 1620, a large number of Protestant refugees from Bohemia (the \"böhmische Exulanten\") came to Zittau, where the Protestant Saxon rulers took them in. Many of them went on to find refuge in surrounding villages, in Dresden, and in Berlin in Brandenburg. Primarily as a result of the near-complete destruction of the city during the Seven Years' War, Zittau's then prosperity is reflected today in only a few exceptional buildings and the cemeteries where the well-to-do were buried.

Art songs are a tradition from most European countries, and now other countries with classical music traditions. German-speaking communities use the term art song (\"Kunstlied\") to distinguish so-called \"serious\" compositions from folk song (\"Volkslied\"). The lyrics are often written by a poet or lyricist and the music separately by a composer. Art songs may be more formally complicated than popular or folk songs, though many early Lieder by the likes of Franz Schubert are in simple strophic form. The accompaniment of European art songs is considered as an important part of the composition. Some art songs are so revered that they take on characteristics of national identification. Art songs emerge from the tradition of singing romantic love songs, often to an ideal or imaginary person and from religious songs. The troubadours and bards of Europe began the documented tradition of romantic songs, continued by the Elizabethan lutenists. Some of the earliest art songs are found in the music of Henry Purcell. The tradition of the romance, a love song with a flowing accompaniment, often in triple meter, entered opera in the 19th century and spread from there throughout Europe. It spread into popular music and became one of the underpinnings of popular songs.

The contract for STA-099 was awarded to North American Rockwell on July 26, 1972, and construction was completed in February 1978. After STA-099's rollout, it was sent to a Lockheed test site in Palmdale, where it spent over 11 months in vibration tests designed to simulate entire shuttle flights, from launch to landing. To prevent damage during structural testing, qualification tests were performed to a safety factor of 1.2 times the design limit loads. The qualification tests were used to validate computational models, and compliance with the required 1.4 factor of safety was shown by analysis. STA-099 was essentially a complete airframe of a Space Shuttle orbiter, with only a mockup crew module installed and thermal insulation placed on its forward fuselage. NASA planned to refit the prototype orbiter \"Enterprise\" (OV-101), used for flight testing, as the second operational orbiter; but \"Enterprise\" lacked most of the systems needed for flight, including a functional propulsion system, thermal insulation, a life support system, and most of the cockpit instrumentation. Modifying it for spaceflight was considered to be too difficult, expensive, and time-consuming. Since STA-099 was not as far along in the construction of its airframe, it would be easier to upgrade to a flight article. Because STA-099's qualification testing prevented damage, NASA found that rebuilding STA-099 as a flight worthy orbiter would be less expensive than refitting \"Enterprise\". Work on converting STA-099 to operational status began in January 1979, starting with the crew module (the pressurized portion of the vehicle), as the rest of the vehicle was still being used for testing by Lockheed. STA-099 returned to the Rockwell plant in November 1979, and the original, unfinished crew module was replaced with the newly constructed model. Major parts of STA-099, including the payload bay doors, body flap, wings, and vertical stabilizer, also had to be returned to their individual subcontractors for rework. By early 1981, most of these components had returned to Palmdale to be reinstalled. Work continued on the conversion until July 1982, when the new orbiter was rolled out as \"Challenger\". \"Challenger\", as did the orbiters built after it, had fewer tiles in its Thermal Protection System than \"Columbia\", though it still made heavier use of the white LRSI tiles on the cabin and main fuselage than did the later orbiters. Most of the tiles on the payload bay doors, upper wing surfaces, and rear fuselage surfaces were replaced with DuPont white Nomex felt insulation. These modifications and an overall lighter structure allowed \"Challenger\" to carry 2,500 lb (1,100 kg) more payload than \"Columbia.\" \"Challenger's\" fuselage and wings were also stronger than \"Columbia's\" despite being lighter. The hatch and vertical-stabilizer tile patterns were also different from those of the other orbiters. \"Challenger\" was also the first orbiter to have a head-up display system for use in the descent phase of a mission, and the first to feature Phase I main engines rated for 104% maximum thrust.", "section_level": 2}, {"title": "Flights and modifications.", "content": "After its first flight in April 1983, \"Challenger\" flew on 85% of all Space Shuttle missions.

Antiqua letterforms were modelled on a synthesis of Roman inscriptional capitals and Carolingian writing. Florentine writer Petrarch was one of the few medieval authors to have written at any length on the handwriting of his time; in his essay on the subject,'he criticized the current scholastic hand, with its laboured strokes (') and exuberant (') letter-forms amusing the eye from a distance, but fatiguing on closer exposure, as if written for other purpose than to be read. For Petrarch the gothic hand violated three principles: writing, he said, should be simple ('), clear (') and orthographically correct. Boccaccio was a great admirer of Petrarch; from Boccaccio's immediate circle this post-Petrarchan \"semi-gothic\" revised hand spread to'in Florence, Lombardy and the Veneto. A more thorough reform of handwriting than the Petrarchan compromise was in the offing. The generator of the new style (\"illustration\") was Poggio Bracciolini, a tireless pursuer of ancient manuscripts, who developed the new humanist script in the first decade of the 15th century. The Florentine bookseller Vespasiano da Bisticci recalled later in the century that Poggio had been a very fine calligrapher of \"\" and had transcribed texts to support himself— presumably, as Martin Davies points out— before he went to Rome in 1403 to begin his career in the papal curia. Berthold Ullman identifies the watershed moment in the development of the new humanistic hand as the youthful Poggio's transcription of Cicero's \"Epistles to Atticus\". By the time the Medici library was catalogued in 1418, almost half the manuscripts were noted as in the \"\". The new script was embraced and developed by the Florentine humanists and educators Niccolò de' Niccoli and Coluccio Salutati. The neat, sloping, humanist cursive invented by the Florentine humanist de' Niccoli in the 1420s and disseminated through his numerous scholars is usually characterized as essentially a rapid version of the same script. Rhiannon Daniels writes, however, that \"this was not humanistic bookhand written cursively, but a running script written with a very fine pen; a modification of contemporary gothic chancery script influenced by humanistic bookhand; hence it is sometimes known as \"\"\". In the late fifteenth century this \"chancery script in the Antique manner\" was further developed by humanists in Rome. Calligraphic forms of this \"chancery italic\" were popularized by the famous Roman writing master Ludovico Arrighi in the early sixteenth century. In the history of Western typography humanist minuscule gained prominence as a model for the typesetter's roman typeface, as it was standardized by Aldus Manutius, who introduced his revolutionary italic typeface based on the chancery hand in Venice, 1501, and was practised by designer-printers Nicolas Jenson and Francesco Griffo; this is the reason why they are also known as \"Venetian types\" and occasionally as \"old style\", differentiated from modern styles by the more or less uniform thickness of all strokes and by slanted serifs.

Olechowski and Płażyński left the party during the 2001–2005 parliamentary term, leaving Tusk as the sole remaining founder, and current party leader. In the 2001 general election the party secured 12.6% of the vote and 65 deputies in the Sejm, making it the largest opposition party to the government led by the Democratic Left Alliance (SLD). In the 2002 local elections PO stood together with Law and Justice in 15 voivodeships (in 14 as POPiS, in Podkarpacie with another centre-right political parties). They stood separately only in Mazovia. In 2005, PO led all opinion polls with 26% to 30% of public support. However, in the 2005 general election, in which it was led by Jan Rokita, PO polled only 24.1% and unexpectedly came second to the 27% garnered by Law and Justice (PiS). A centre-right coalition of PO and PiS (nicknamed:PO-PiS) was deemed most likely to form a government after the election. Yet the putative coalition parties had a falling out in the wake of the fiercely contested Polish presidential election of 2005. Lech Kaczyński (PiS) won the second round of the presidential election on 23 October 2005 with 54% of the vote, ahead of Tusk, the PO candidate. Due to the demands of PiS for control of all the armed ministries (the Defence Ministry, the Ministry of the Interior and the Ministry of Foreign Affairs) and the office of the Prime Minister, PO and PiS were unable to form a coalition. Instead, PiS formed a coalition government with the support of the League of Polish Families (LPR) and Self-Defense of the Republic of Poland (SRP). PO became the opposition to this PiS-led coalition government. The PiS-led coalition fell apart in 2007 amid corruption scandal with Andrzej Lepper and Tomasz Lipiec and internal leadership disputes. These events led to the new elections in 2007. In the 21 October 2007 parliamentary election, PO won 41.51% of the popular vote and 209 out of 460 seats (now 201) in the Sejm and 60 out of 100 seats (now 56) in the Senate of Poland. Civic Platform, now the largest party in both houses of parliament, subsequently formed a coalition with the Polish People's Party (PSL). At the 2010 Polish presidential election, following the Smolensk air disaster which killed the incumbent Polish president Lech Kaczyński, Tusk decided not to present his candidature, considered an easy possible victory over PiS leader Jarosław Kaczyński. During the PO primary elections, Bronisław Komorowski defeated the Oxford-educated, PiS defector Foreign Minister Radosław Sikorski. At the polls, Komorowski defeated Jarosław Kaczyński, ensuring PO dominance over the current Polish political landscape. In November 2010, local elections granted Civic Platform about 30.1 percent of the votes and PiS at 23.2 percent, an increase for the former and a drop for the latter compared to the 2006 elections. PO succeeded in winning four consecutive elections (a record in post-communist Poland), and Tusk remains as kingmaker. PO's dominance is also a reflection of left-wing weakness and divisions on both sides of the political scene, with PiS suffering a splinter in Autumn 2010.

Located at a Jurassic rift, it was formed by glaciers during the last ice age. It stretches about in a north-south direction and is about across at its widest point. Except at its outlet, the Königsseer Ache at the village of Königssee, the lake is similar to a fjord, being surrounded by the steeply-rising flanks of mountains up to, including the Watzmann massif in the west. The literal translation of the name, Königssee, appears to be \"king's lake\"; however while does indeed mean \"king\", there had been no Bavarian kings since the days of Louis the German until Elector Maximilian I Joseph assumed the royal title in 1806. Therefore, the name more probably stems from the first name \"Kuno\" of local nobles, who appear in several historical sources referring to the donation of the Berchtesgaden Provostry in the twelfth century; the lake was formerly called \"Kunigsee\". The Königssee Railway (\"Königsseebahn\") served the lake from 1909 until 1965. Its last tracks were dismantled during 1971, and the former station of the Königssee Railway in Berchtesgaden (Königsseer Bahnhof) was demolished in 2012. The only remaining element of the railway is the Königsee station, which is now a restaurant. The track route is mostly used as a walking path. In 1944 a sub-camp of the Dachau concentration camp was located near where Heinrich Himmler had a residence built at Schönau for his mistress Hedwig Potthast. The lake is noted for its clear water and is advertised as the cleanest lake in Germany. For this reason, only electric-powered passenger ships, rowing, and pedal boats have been permitted on the lake since 1909. Passenger services along the length of the lake are operated by the Bayerische Seenschifffahrt company and call at Seelände (Schönau), St. Bartholomä, Salet (mid-April to mid-October), and Kessel (on request). In ideal conditions, the longest tour takes two hours from Seelände to Salet. Swimming is permitted except in the lock area at Seelände. Due to its picturesque setting, the lake and surrounding parklands are very popular with tourists and hikers. In addition, the surrounding sheer rock walls create an echo known for its clarity. On boat tours, it has become traditional to stop and play a flugelhorn or trumpet to demonstrate the echo. Previously demonstrated by shooting a cannon, the echo can be heard to reverberate up to seven times. The trumpeter plays along with the echo, so that there can seem to be as many as seven players. St. Bartholomä, a famous pilgrimage church with an inn nearby, is located on a peninsula about halfway down the western lake shore. The small Christlieger island is located near its northern end. South of the Königssee, separated by the \"Salet\" moraine, is the smaller Obersee lake with the high Röthbach waterfall. Because there is no lakeside path on the steep shore of the Königssee, St. Bartholomä and the southern edge can only be reached by boat, or via hiking trails up the surrounding mountains, except during harsh winters when the lake freezes over.

The dukes of Brunswick-Lüneburg turned the place into a secondary residence in the 17th century and it enjoyed its heyday under Duke Louis Rudolf (1690–1731), the second son of Anthony Ulrich of Wolfenbüttel. Rudolf was given Blankenburg in 1707 as a \"\". At the same time the County of Blankenburg was elevated to the status of an imperial principality (\"Reichsfürstentum\") which was ruled independently until 1731, but then, because Louis Rudolf became a duke, was reunited with Brunswick where it remained. The present-day Little Castle with its terraced garden and Baroque pleasure garden stems from that period. From 1807 to 1813 Blankenburg belonged to the Kingdom of Westphalia. In the Seven Years' War the absolute neutrality of the town made it a safe refuge for the Brunswick court. Louis XVIII also stayed in Blankenburg under the name of Count of Lille from 24 August 1796 to 10 February 1798, after his escape from Dillingen. In the early days of Nazi era, those who opposed the Nazi regime were persecuted and murdered. In a notorious campaign by Brunswick SS commander, Jeckeln, in September 1933, 140 communists and social democrats were herded together in the inn, \"Zur Erholung\". Here and in the \"Blankenburger Hof\" they were severely beaten, some dying as a result. During the Second World War the Blankenburg-Oesig subcamp of Buchenwald concentration camp was set up in the Dr. Dasch (Harzer Werke) Monastery Works and, shortly thereafter, subordinated to Mittelbau-Dora concentration camp. Here some 500 prisoners had to carry out forced labour in the monastery factory and Oda Works. In addition, there was a work camp run by the Gestapo for \"half-Jews\" who were forced to do hard labour. Another camp was occupied in February 1945 by inmates of the Auschwitz subcamp of Fürstengrube and managed as Blankenburg Regenstein subcamp. As part of the division of Germany into occupation zones in 1945, Blankenburg district was actually assigned to the British zone in accordance with the Potsdam Conference and London Protocol. But because the larger eastern part of the district was linked to the rest of the British zone only by a road and a railway, the boundary was adjusted and Blankenburg incorporated into the Soviet zone. The largest part of the district thus ended up later in East Germany and became part of the state of Saxony-Anhalt. The main part of the former Free State of Brunswick went to the British zone and thus became part of Lower Saxony. The tunnels of the Regenstein-Blankenburg facility were used from 1974 by the National People's Army (NVA) in the GDR as a large ammunition depot. In 1992 the Bundeswehr were given the 8 km long tunnel system and established there, \"the largest underground pharmacy in the world\", both for routine Bundeswehr missions, but also for disaster relief around the world and for cases of serious military \"operations\".", "section_level": 1}, {"title": "Jewish life in Blankenburg.", "content": "At end of the 12th century, the abbess of Quedlinburg pledged estates to Blankenburg Jews.

Some professional garden designers are also landscape architects, a more formal level of training that usually requires an advanced degree and often a state license. Elements of garden design include the layout of hard landscape, such as paths, rockeries, walls, water features, sitting areas and decking, as well as the plants themselves, with consideration for their horticultural requirements, their season-to-season appearance, lifespan, growth habit, size, speed of growth, and combinations with other plants and landscape features. Consideration is also given to the maintenance needs of the garden, including the time or funds available for regular maintenance, which can affect the choices of plants regarding speed of growth, spreading or self-seeding of the plants, whether annual or perennial, and bloom-time, and many other characteristics. Garden design can be roughly divided into two groups, formal and naturalistic gardens. The most important consideration in any garden design is how the garden will be used, followed closely by the desired stylistic genres, and the way the garden space will connect to the home or other structures in the surrounding areas. All of these considerations are subject to the limitations of the budget.

Gardeners produce methane by compacting the soil and making it anaerobic, and by allowing their compost heaps to become compacted and anaerobic. Gardeners produce nitrous oxide by applying excess nitrogen fertiliser when plants are not actively growing so that the nitrogen in the fertiliser is converted by soil bacteria to nitrous oxide. Gardeners can help to prevent climate change in many ways, including the use of trees, shrubs, ground cover plants and other perennial plants in their gardens, turning garden waste into soil organic matter instead of burning it, keeping soil and compost heaps aerated, avoiding peat, switching from power tools to hand tools or changing their garden design so that power tools are not needed, and using nitrogen-fixing plants instead of nitrogen fertiliser.", "section_level": 2}, {"title": "Irrigation.", "content": "Some gardeners manage their gardens without using any water from outside the garden.

He showed an early predilection for solitary and gloomy places and the making of verses, for which he had no other model than hymnals. At the age of twelve, Bürger was practically adopted by his maternal grandfather, Bauer, at Aschersleben, who sent him to the Pädagogium at Halle. He learned Latin with difficulty. In 1764 he passed to the University of Halle, as a student of theology, which, however, he soon abandoned for the study of jurisprudence. There he fell under the influence of Christian Adolph Klotz (1738–1771), who directed Bürger's attention to literature and encouraged his natural disposition to a wild and unregulated life. In consequence of his dissipated habits, he was in 1767 recalled by his grandfather, but on promising to reform was in 1768 allowed to enter the University of Göttingen as a law student. As he continued his wild career, however, his grandfather withdrew his support and he was left to his own devices. Meanwhile, he had made fair progress with his legal studies, and had the good fortune to form a close friendship with a number of young men of literary tastes. He studied the ancient classics and the best works in French, Italian, Spanish and English, particularly Shakespeare, and the old English and Scottish ballads. Thomas Percy's \"Reliques of Ancient English Poetry\" was his constant companion. In the Göttingen \"Musenalmanach\", edited by Heinrich Christian Boie and Friedrich Wilhelm Gotter, Bürger's first poems were published, and by 1771 he had already become widely known as a poet. In 1772, through Boie's influence, Bürger obtained the post of \"Amtmann\" or district magistrate at Altengleichen near Göttingen. His grandfather was now reconciled to him, paid his debts and established him in his new sphere of activity. Meanwhile, he kept in touch with his Göttingen friends, and when the \"Göttinger Bund\" or \"Hain\" (\"Göttinger Hainbund\") was formed, Bürger, though not himself a member, kept in close touch with it. In 1773, the ballad \"Lenore\" was published in the \"Musenalmanach\". This poem, which in dramatic force and in its vivid realization of the weird and supernatural remains without a rival, made his name a household word in Göttingen. \"Lenore\" was paraphrased by Walter Scott under the title \"William and Helen\" and Goethe did the same under the title \"Bride of Corinth\". In 1774 he married Dorette Leonhart, the daughter of a Hanoverian official; but his passion for his wife's younger sister Auguste (the \"Molly\" of his poems and elegies) rendered the union unhappy and unsettled his life. In 1778 Bürger became editor of the \"Musenalmanach\", a position he retained until his death. In the same year published the first collection of his poems. In 1780 he took a farm at Appenrode, but in three years lost so much money that he had to abandon the venture. Pecuniary troubles oppressed him, and being accused of neglecting his official duties, and feeling his honour attacked, he gave up his official position and removed in 1784 to Göttingen, where he established himself as \"Privatdozent\". Shortly before his removal there his wife died (July 30, 1784), and on June 29 in the next year he married his sister-in-law \"Molly.\" Her death in childbirth on January 9, 1786 affected him deeply. He appeared to lose at once all courage and all bodily and mental vigour. He still continued to teach in Göttingen; at the jubilee of the foundation of the university in 1787 he was made an honorary doctor of philosophy, and in 1789 was appointed extraordinary professor in that faculty, though without a stipend. He was obliged to gain his living by poorly rewarded translations for booksellers. In 1790, he married a third time, his wife being a certain Elise Hahn, who, enchanted with his poems, had offered him her heart and hand. Only a few weeks of married life with his \"Schwabenmädchen\" sufficed to prove his mistake, and after two and a half years he divorced her. Deeply wounded by Schiller's criticism, in the 14th and 15th part of the \"Allgemeine Literaturzeitung\" of 1791, of the second edition of his poems, disappointed, wrecked in fortune and health, Bürger eked out a precarious existence as a teacher in Göttingen until, ill with tuberculosis, he died there on June 8, 1794. The government of Hanover afforded him some assistance shortly before his death. Bürger's talent for popular poetry was very considerable, and his ballads are among the finest in the German language. Besides \"Lenore\", \"Das Lied vom braven Manne\", \"Die Kuh\", \"Der Kaiser und der Abt\" and \"Der wilde Jäger\" are famous. Among his purely lyrical poems, but few have earned a lasting reputation; but mention may be made of \"Das Blümchen Wunderhold\", \"Lied an den lieben Mond\", and a few love songs.

In the same year he witnessed the Hungarian Uprising and began to advocate the ideals of a democratic socialism beyond the official line of the Socialist Unity Party. He obtained his \"Abitur\" degree in 1958 and completed an apprenticeship as an industrial clerk.

Dutschke also advocated that the transformation of Western societies should go hand in hand with Third World liberation movements and with democratization in communist countries of Central and Eastern Europe. He was from a pious Lutheran family and his socialism had strongly Christian roots; he called Jesus Christ the \"greatest revolutionary\", and in Easter 1963, he wrote that \"Jesus is risen. The decisive revolution in world history has happened – a revolution of all-conquering love. If people would fully receive this revealed love into their own existence, into the reality of the 'now', then the logic of insanity could no longer continue.\" Benno Ohnesorg's death in 1967 at the hands of German police pushed some in the student movement toward increasingly extremist violence and the formation of the Red Army Faction. The violence against Dutschke further radicalised parts of the student movement into committing several bombings and murders. Dutschke rejected this direction and feared that it would harm or cause the dissolution of the student movement. Instead he advocated a 'long march through the institutions' of power to create radical change from within government and society by becoming an integral part of the machinery. The meaning of Dutschke's idea of a \"long march through the institutions\" is in fact highly contested: most historians of '68 in West Germany understand it to mean advocating setting up an alternative society and recreating the institutions which were seen by Dutschke as beyond reform in their current state.

Dutschke was accepted at Clare Hall, a graduate college at the University of Cambridge, to finish his degree in 1969, but in 1971 the Conservative government under Edward Heath expelled him and his family as an \"undesirable alien\" who had engaged in \"subversive activity\", causing a political storm in London. They then moved to Århus, Denmark, after professor Johannes Sløk had offered him a job at the University of Aarhus which made it possible for Dutschke to gain a Danish residence permit. Dutschke re-entered the German political scene after protests against the building of nuclear power plants activated a new movement in the mid-1970s.

For hundreds of years, book bindings had functioned as a protective device for the expensively printed or hand-made pages, and as a decorative tribute to their cultural authority. In the 1820s great changes began to occur in how a book might be covered, with the gradual introduction of techniques for mechanical book-binding. Cloth, and then paper, became the staple materials used when books became so cheap—thanks to the introduction of steam-powered presses and mechanically produced paper—that to have them hand-bound became disproportionate to the cost of the book itself. Not only were the new types of book-covers cheaper to produce, they were also printable, using multi-colour lithography, and later, halftone illustration processes.

Another highly influential early book cover designer was Aubrey Beardsley, thanks to his striking covers for the first four volumes of \"The Yellow Book\" (1894–5). In the post-war era, book covers have become vitally important as the book industry has become commercially competitive. Covers now give detailed hints about the style, genre and subject of the book, while many push design to its limit in the hope of attracting sales attention. This can differ from country to country because of other tastes of the markets. So translated books can also have different book-accessories such as toys belonging to children's books, for example \"Harry Potter\".

In etching, for example, the plate is pre-covered in a thin, acid-resistant resin or wax \"ground\". Using etching needles or burins, the artist or writer (etcher) engraves their image (therefore to be only where the plate beneath is exposed). The plate's ground side is then dipped into acid, or the acid poured onto it. The acid bites into the surface of the plate where it was exposed. Biting is a printmaking term to describe the acid's etching, or incising, of the image; its duration depends on the acid strength, metal's reactivity, temperature, air pressure and the depth desired. After the plate is sufficiently bitten it is removed from the acid bath, the ground is removed gently and the plate is usually dried or cleaned. To print an intaglio plate, ink or inks are painted, wiped and/or dabbed into the recessed lines (such as with brushes/rubber gloves/rollers). The plate is then rubbed with tarlatan cloth to remove most of its waste (surface ink) and a final smooth wipe is often done with newspaper or old public phone book pages, leaving it in the incisions. Dampened imprint (product) paper will usually be fed against the plate, covered by a blanket, so when pressed by rolling press it is squeezed into the plate's ink-filled grooves with uniform very high pressure.

Engraving had been used by goldsmiths to decorate metalwork, including armor, musical instruments and religious objects since ancient times, and the niello technique, which involved rubbing an alloy into the lines to give a contrasting color, also goes back to late antiquity. Scholars and practitioners of printmaking have suggested that the idea of making prints from engraved plates may well have originated with goldsmiths' practices of taking an impression on paper of a design engraved on an object, in order to keep a record of their work, or to check the quality. Martin Schongauer was one of the earliest known artists to exploit the copper-engraving technique, and Albrecht Dürer is one of the most famous intaglio artists. Italian and Dutch engraving began slightly after the Germans, but were well developed by 1500. Drypoint and etching were also German inventions of the fifteenth century, probably by the Housebook Master and Daniel Hopfer respectively. In the nineteenth century, Viennese printer Karel Klíč introduced a combined intaglio and photographic process. Photogravure retained the smooth continuous tones of photography but was printed using a chemically-etched copper plate. This permitted a photographic image to be printed on regular paper, for inclusion in books or albums. In the 1940s and 1950s the Italian security printer Gualtiero Giori brought intaglio printing into the era of high-technology by developing the first ever six-colour intaglio printing press, designed to print banknotes which combined more artistic possibilities with greater security.", "section_level": 1}, {"title": "Current use.", "content": "At one time intaglio printing was used for all mass-printed materials including banknotes, stock certificates, newspapers, books, maps and magazines, fabrics, wallpapers and sheet music.

From the end of the 12. century to the early 13. century, German settlers from nearby German-speaking regions came as settlers, craftsmen and miners to develop the region's economy. Eventually, Karlovy Vary/Karlsbad became a town with a German-speaking population. Around 1350, Charles IV, Holy Roman Emperor organized an expedition into the forests surrounding modern-day Karlovy Vary during a stay in Loket. On the site of a spring, he established a spa mentioned as \"in dem warmen Bade bey dem Elbogen\" in German, (\"Hot Spas at the ellbow\") or \"Horké Lázně u Lokte\". The location was subsequently named \"Karlovy Vary\" after the emperor, who extolled the healing powers of the hot springs, at least according to legend. Charles IV granted the town privileges on 14 August 1370. Earlier settlements can also be found on the outskirts of today's town. An important political event took place in the town in 1819, with the issuing of the Carlsbad Decrees following a conference there. Initiated by the Austrian Minister of State Klemens von Metternich, the decrees were intended to implement anti-liberal censorship within the German Confederation. Due to publications produced by physicians such as David Becher and Josef von Löschner, the town developed into a famous spa resort in the 19th century and was visited by many members of European aristocracy as well as celebrities from many fields of endeavour.

The village was then resettled during the 16th century by mostly German-speaking colonists. In the 18th century, the first artificial jewellery was produced and the first exporter, J. F. Schwan, spread the town's name throughout Europe. The village of Gablonz was declared a \"market town\" by Emperor Francis II on 21 April 1808 and was given full town status by Emperor Francis Joseph on 28 March 1866.

A steady supply of a wide range of glass and artificial jewellery products flowed out of the town. This industrial advancement also improved the quality of life, and Jablonec's appearance changed dramatically. However, Black Friday in 1929 damaged the glass and jewellery industry and the crisis of the 1930s with its unemployment and hunger led to great support of Nazis.

In medieval Latin European documents, a land grant in exchange for service continued to be called a \"beneficium\" (Latin). Later, the term \"feudum\", or \"feodum\", began to replace \"beneficium\" in the documents. The first attested instance of this is from 984, although more primitive forms were seen up to one hundred years earlier. The origin of the \"feudum\" and why it replaced \"beneficium\" has not been well established, but there are multiple theories, described below. The most widely held theory is put forth by Marc Bloch that it is related to the Frankish term \"*fehu-ôd\", in which \"*fehu\" means \"cattle\" and \"-ôd\" means \"goods\", implying \"a moveable object of value.\" When land replaced currency as the primary store of value, the Germanic word \"*fehu-ôd\" replaced the Latin word \"beneficium\". This Germanic origin theory was also shared by William Stubbs in the 19th century. A theory put forward by Archibald R. Lewis is that the origin of 'fief' is not \"feudum\" (or \"feodum\"), but rather \"foderum\", the earliest attested use being in Astronomus's \"Vita Hludovici\" (840). In that text is a passage about Louis the Pious which says \"annona militaris quas vulgo foderum vocant\", which can be translated as \"(Louis forbade that) military provender which they popularly call 'fodder' (be furnished).\" A theory by Alauddin Samarrai suggests an Arabic origin, from \"fuyū\" (the plural of \"fay\", which literally means \"the returned\", and was used especially for 'land that has been conquered from enemies that did not fight'). Samarrai's theory is that early forms of 'fief' include \"feo\", \"feu\", \"feuz\", \"feuum\" and others, the plurality of forms strongly suggesting origins from a loanword. First use of these terms was in Languedoc, one of the least-Germanized areas of Europe, and bordering Muslim Spain, where the earliest use of \"feuum\" as a replacement for \"beneficium\" can be dated to 899, the same year a Muslim base at Fraxinetum (La Garde-Freinet) in Provence was established. It is possible, Samarrai says, that French scribes, writing in Latin, attempted to transliterate the Arabic word \"fuyū\" (the plural of \"fay\"), which was being used by the Muslims at the time, resulting in a plurality of forms - \"feo, feu, feuz, feuum\" and others - from which eventually \"feudum\" derived. Samarrai, however, also advises medieval and early modern Muslim scribes often used etymologically \"fanciful roots\" in order to claim the most outlandish things to be of Arabian or Muslim origin. In the 10th and 11th centuries the Latin terms for fee could be used either to describe dependent tenure held by a man from his lord, as the term is used now by historians, or it could mean simply \"property\" (the manor was, in effect, a small fief). It lacked a precise meaning until the middle of the 12th century, when it received formal definition from land lawyers. In English usage, the word \"fee\" is first attested around 1250–1300 (Middle English); the word \"fief\" from around 1605–15. In French, the term \"fief\" is found from the middle of the 13th century (Old French), derived from the 11th-century terms \"feu\", \"fie\". The odd appearance of the second \"f\" in the form \"fief\" may be due to influence from the verb \"fiever\" 'to grant in fee'. In French, one also finds \"seigneurie\" (land and rights possessed by a \"seigneur\" or \"lord\", 12th-century), which gives rise to the expression \"seigneurial system\" to describe feudalism.", "section_level": 1}, {"title": "Early feudal grants.", "content": "Originally, vassalage did not imply the giving or receiving of landholdings (which were granted only as a reward for loyalty), but by the 8th century the giving of a landholding was becoming standard. The granting of a landholding to a vassal did not relinquish the lord's property rights, but only the use of the lands and their income; the granting lord retained ultimate ownership of the fee and could, technically, recover the lands in case of disloyalty or death. In Francia, Charles Martel was the first to make large-scale and systematic use (the practice had remained until then sporadic) of the remuneration of vassals by the concession of the usufruct of lands (a \"beneficatium\" or \"benefice\" in the documents) for the life of the vassal, or, sometimes extending to the second or third generation. By the middle of the 10th century, fee had largely become hereditary. The eldest son of a deceased vassal would inherit, but first he had to do homage and fealty to the lord and pay a \"relief\" for the land (a monetary recognition of the lord's continuing proprietary rights over the property). Historically, the fees of the 11th and the 12th century derived from two separate sources. The first was land carved out of the estates of the upper nobility. The second source was allodial land transformed into dependent tenures. During the 10th century in northern France and the 11th century in France south of the Loire, local magnates either recruited or forced the owners of allodial holdings into dependent relationships and they were turned into fiefs. The process occurred later in Germany, and was still going on in the 13th century. In England, Henry II transformed them into important sources of royal income and patronage. The discontent of barons with royal claims to arbitrarily assessed \"reliefs\" and other feudal payments under Henry's son King John resulted in Magna Carta of 1215. Eventually, great feudal lords sought also to seize governmental and legal authority (the collection of taxes, the right of high justice, etc.) in their lands, and some passed these rights to their own vassals.

He did his \"Abitur\" at the \"Altes Gymnasium\" in the city of Oldenburg, and studied theology at Tübingen. After three terms, Bultmann went to the University of Berlin for two terms, and finally to Marburg for two more terms. He received his degree in 1910 from Marburg with a dissertation on the Epistles of St Paul, written under the supervision of Johannes Weiss. After submitting a Habilitation two years later, he became a lecturer on the New Testament at Marburg. Bultmann married Helene Feldmann on 6 August 1917. The couple had three daughters. Bultmann's wife died in 1973. After brief lectureships at Breslau and Giessen, Bultmann returned to Marburg in 1921 as a full professor, and stayed there until his retirement in 1951. From autumn 1944 until the end of the Second World War in 1945 he took into his family Uta Ranke-Heinemann, who had fled the bombs and destruction in Essen. Bultmann was a student of Hermann Gunkel, Johannes Weiss, and Wilhelm Heitmüller. His doctoral students included Hans Jonas, Ernst Käsemann, Günther Bornkamm, Helmut Koester, and Ernst Fuchs. He also taught Hannah Arendt. He was a member of the Confessing Church and critical towards Nazism. He spoke out against the mistreatment of Jews, against nationalistic excesses and against the dismissal of non-Aryan Christian ministers. He did not, however, speak out against \"the antiSemitic[sic] laws which had already been promulgated\" and he was philosophically limited in his ability to \"repudiate, in a comprehensive manner, the central tenets of Nazi racism and antiSemitism[sic].\" Bultmann became friends with Martin Heidegger who taught at Marburg for five years, and Heidegger's views on existentialism had an influence on Bultmann's thinking. What arose from this friendship was a \"sort of comradery\" grounded on an active and open dialogue between Bultmann and Heidegger from 1923-1928. However, Bultmann himself stated that his views could not simply be reduced to thinking in Heideggerian categories, in that \"the New Testament is not a doctrine about our nature, about our authentic existence as human beings, but a proclamation of this liberating act of God.\" He died on 30 July 1976 in Marburg.", "section_level": 1}, {"title": "Theological approaches.", "content": "Bultmann's \"History of the Synoptic Tradition\" (1921) remains highly influential as a tool for biblical research, even among scholars who reject his analyses of the conventional rhetorical pericopes (narrative units) which comprise the gospels, and the historically-oriented principles of \"form criticism\" of which Bultmann was the most influential exponent. According to Bultmann's definition, \"[t]he aim of form-criticism [\"sic\"] is to determine the original form of a piece of narrative, a dominical saying or a parable. In the process we learn to distinguish secondary additions and forms, and these in turn lead to important results for the history of the tradition.\" In 1941 Bultmann applied form criticism to the Gospel of John, in which he distinguished the presence of a lost Signs Gospel on which John — alone of the evangelists — depended. His monograph, \"Das Evangelium des Johannes\", highly controversial at the time, became a milestone in research into the historical Jesus. The same year his lecture \"New Testament and Mythology: The Problem of Demythologizing the New Testament Message\" called on interpreters to demythologize The New Testament, in particular he argued for replacing supernatural biblical interpretations with temporal and existential categorizations. His argument, in many ways, reflected a hermeneutical adaption of the existentialist thought of his colleague at the time, the philosopher Martin Heidegger. This approach led Bultmann to reject doctrines such as the pre-existence of Christ. Bultmann believed his endeavors in this regard would make accessible to modern audiences — already immersed in science and technology — the significance (or existential quality) of Jesus' teachings. Bultmann thus thought of his endeavor of \"demythologizing the New Testament proclamation\" as fundamentally an evangelism task, clarifying the \"kerygma\", or gospel proclamation, by stripping it of elements of the first-century \"mythical world picture\" that had potential to alienate modern people from Christian faith: It is impossible to repristinate a past world picture by sheer resolve, especially a \"mythical\" world picture, now that all of our thinking is irrevocably formed by science. A blind acceptance of New Testament mythology would be simply arbitrariness; to make such acceptance a demand of faith would be to reduce faith to a work. Bultmann saw theology in existential terms, and maintained that the New Testament was a radical text, worthy of understanding yet questioned in his time because of the prevailing Protestant conviction in a supernatural interpretation. In both the boasting of legalists \"who are faithful to the law\" and the boasting of the philosophers \"who are proud of their wisdom\", Bultmann finds a \"basic human attitude\" of \"highhandedness that tries to bring within our own power even the submission that we know to be our authentic being\". Standing against all human high-handedness is the New Testament, \"which claims that we can in no way free ourselves from our factual fallenness in the world but are freed from it only by an act of God... the salvation occurrence that is realized in Christ.\" Bultmann remained convinced that the narratives of the life of Jesus offered theology in story form, teaching lessons in the familiar language of myth. They were not to be excluded, but given explanation so they could be understood for today. Bultmann thought faith should become a present-day reality. To Bultmann, the people of the world appeared to be always in disappointment and turmoil. Faith must be a determined vital act of will, not a culling and extolling of \"ancient proofs\". Bultmann said about salvation and eternity: \"As from now on there are only believers and unbelievers, so there are also now only saved and lost, those who have life and those who are in death.\" Bultmann carried Form criticism so far as to call the historical value of the gospels into serious question. Some scholars, such as Craig L. Blomberg, criticized Bultmann and other critics for excessive skepticism regarding the historical reliability of the gospel narratives. The full impact of Bultmann was felt with the English translation of many of his works, notably \"Kerygma and Mythos\" (1948).", "section_level": 1}], "src_summary": "Rudolf Karl Bultmann (; 20 August 1884 – 30 July 1976) was a German Lutheran theologian and professor of the New Testament at the University of Marburg.

The ship arrived at Svolvær on Monday 3 July at 8pm after 351⁄2 hours and at Hammerfest on Wednesday 5 July after 67 hours. She was commanded by founder of the route Richard With. At that time this was the fastest route between northern and southern Norway, and this resulted in the route being named Hurtigruten (express route). As of 2008, the Trondheim–Svolvær trip took 33 hours and the Trondheim–Hammerfest trip took 41 hours 15 min. Before Hurtigruten opened, only Vesteraalens Dampskibsselskab was willing to make the trip through the then poorly-charted waters; the voyage was especially difficult during the long, dark winters. Hurtigruten was a substantial breakthrough for communities along its path. Mail from central Norway to Hammerfest, which used to take three weeks in summer and five months in winter, could now be delivered in seven days. Encouraged by Vesteraalens' early success, several other shipping companies obtained a concession to operate the route, extended to run between Bergen in the southwest and Kirkenes in the far northeast. A fleet of 11 ships visits each of the 34 ports daily, both northbound and southbound. Until the 1940s most ports north of Trondheim could not be reached by road from Oslo, so the sea was the only means of access. Beginning in the 1960s, the role of Hurtigruten changed, in part because of the construction of a local airport network and road improvements. Operating subsidies were gradually phased out, and the operators put more emphasis on tourism. New, bigger and more luxurious ships were introduced in the 1980s, with attention given to hot tubs, bars, restaurants and other comforts. However, Hurtigruten still serves important passenger and cargo needs, and operates 365 days a year. The last two independent shipping companies, Ofotens og Vesteraalens Dampskibsselskab (OVDS) and Troms Fylkes Dampskibsselskap (TFDS), merged on 1 March 2006 as the Hurtigruten Group, a year later becoming Hurtigruten ASA.

Production involves the selection of appropriate words and the appropriate form of those words from the lexicon and morphology, and the organization of those words through the syntax. Then, the phonetic properties of the words are retrieved and the sentence is uttered through the articulations associated with those phonetic properties. In linguistics (articulatory phonetics), articulation refers to how the tongue, lips, jaw, vocal cords, and other speech organs used to produce sounds are used to make sounds. Speech sounds are categorized by manner of articulation and place of articulation. Place of articulation refers to where the airstream in the mouth is constricted. Manner of articulation refers to the manner in which the speech organs interact, such as how closely the air is restricted, what form of airstream is used (e.g. pulmonic, implosive, ejectives, and clicks), whether or not the vocal cords are vibrating, and whether the nasal cavity is opened to the airstream. The concept is primarily used for the production of consonants, but can be used for vowels in qualities such as voicing and nasalization. For any place of articulation, there may be several manners of articulation, and therefore several homorganic consonants. Normal human speech is pulmonic, produced with pressure from the lungs, which creates phonation in the glottis in the larynx, which is then modified by the vocal tract and mouth into different vowels and consonants.

For example, the fact that children often make the error of over-regularizing the -ed past tense suffix in English (e.g. saying'singed' instead of'sang') shows that the regular forms are acquired earlier. Speech errors associated with certain kinds of aphasia have been used to map certain components of speech onto the brain and see the relation between different aspects of production: for example, the difficulty of expressive aphasia patients in producing regular past-tense verbs, but not irregulars like'sing-sang' has been used to demonstrate that regular inflected forms of a word are not individually stored in the lexicon, but produced from affixation of the base form.", "section_level": 2}, {"title": "Perception.", "content": "Speech perception refers to the processes by which humans can interpret and understand the sounds used in language.

Research into speech perception also has applications in building computer systems that can recognize speech, as well as improving speech recognition for hearing- and language-impaired listeners. Speech perception is categorical, in that people put the sounds they hear into categories rather than perceiving them as a spectrum. People are more likely to be able to hear differences in sounds across categorical boundaries than within them. A good example of this is voice onset time (VOT). For example, Hebrew speakers, who distinguish voiced /b/ from voiceless /p/, will more easily detect a change in VOT from -10 ( perceived as /b/ ) to 0 ( perceived as /p/ ) than a change in VOT from +10 to +20, or -10 to -20, despite this being an equally large change on the VOT spectrum.", "section_level": 1}, {"title": "Repetition.", "content": "In speech repetition, speech being heard is quickly turned from sensory input into motor instructions needed for its immediate or delayed vocal imitation (in phonological memory).

The lexicon is accessed in Wernicke's area, and these words are sent via the arcuate fasciculus to Broca's area, where morphology, syntax, and instructions for articulation are generated. This is then sent from Broca's area to the motor cortex for articulation. Paul Broca identified an approximate region of the brain in 1861 which, when damaged in two of his patients, caused severe deficits in speech production, where his patients were unable to speak beyond a few monosyllabic words. This deficit, known as Broca's or expressive aphasia, is characterized by difficulty in speech production where speech is slow and labored, function words are absent, and syntax is severely impaired, as in telegraphic speech. In expressive aphasia, speech comprehension is generally less affected except in the comprehension of grammatically complex sentences.

The initialisms ᴄᴇ, ʙᴄᴇ, ᴀᴍ, and ᴘᴍ are often typeset in small caps. In printed plays and stage directions, small caps are usually used for the names of characters before their lines. French and some British publications use small caps to indicate the surname by which someone with a long formal name is to be designated in the rest of a written work. An elementary example is Don Qᴜɪxᴏᴛᴇ de La Mancha. Similarly, they are used for those languages in which the surname comes first, such as the Romanization Mᴀᴏ Zedong.

Archaeological excavations of soil layers indicate that there was a settlement in the area during the Migration period, at the turn of the 5th and 6th centuries. The place was then abandoned for approximately hundred years. At the end of the 8th or the beginning of the 9th century the area was leveled and a new settlement constructed. The earliest evidence of fortifications dates to the first half of the 9th century. In the second half of the 9th century there was a central fortified area and two suburbs, to the north and south of the center. These became enclosed and fortified between the end of the 9th and the 10th centuries. In the 8th century there was a West Slavic settlement on the island. The name of the local tribe was recorded as \"Velunzani\" (Wolinians) in the 9th century by the Bavarian Geographer, and is considered a sub-tribe of both the Slavic Pomeranians and the Veleti (later Lutizians). The Wolinians are described by Jan Maria Piskorski as the most powerful Pomeranian tribe, due to their control of a multi-ethnic emporium at the site of the present-day town. Similar emporia were also set up elsewhere along the southern coastline of the Baltic Sea since the 8th century. This emporium, by contemporary chronicles referred to as \"Jumne\" or \"Julin\", began to prosper in the 9th century. Archaeological research has revealed seaside fortifications that have been dated back to the beginning 10th century, and also remnants of older fortifications, probably pointing to an earlier burgh with an adjacent open settlement. In the 960s, the Jewish merchant Ibrahim ibn Jakub described the settlement as a town with several thousand inhabitants and twelve gates. Besides the Wolinians, there were Scandinavian, Saxons and Rus' (people). Later, the town was mentioned in the chronicles of Adam of Bremen. Adam mentioned a lighthouse, which he described as \"the lamp of Vulcan\". All these descriptions contributed to the Vineta legend. Though other towns are also considered possible locations of Vineta, it is believed today to be identical with Wolin. The same is true for Jomsborg, a stronghold set up by Danish king Harald Bluetooth and Swedish prince Styrbjörn in the course of Harald's internal struggles with his son, Sweyn Forkbeard, in the 970s or 980s, which housed a garrison of soldiers known as Jomsvikings. In the late 10th century, the Polish dukes Mieszko I and Bolesław I Chrobry subdued parts of Pomerania and also fought the Wolinians. Despite a victory of Mieszko in a 967 battle, the Polish dukes, according to Jan Maria Piskorski, did not succeed to subdue the area. Władysław Filipowiak however says that the battle \"probably led to the establishment of the rule of the winner over the town.\" In 1982, Joachim Herrmann suggested that Boleslaw had established a Viking colony under Palnatoki there to defend his realm, a thesis that in 2000 had been revisited by Leszek Słupecki who like Władysław Duczko (2000) called for further research on resident Vikings in Jomsborg/Wolin. Filipowiak says that, based on the archaeological evidence, \"there might actually have existed in Wolin a mercenary company placed by the Piast rulers in the unruly town, which in 1007 informed the German Emperor that Boleslaw the Brave had been weaving a dangerous plot,\" but also points out the need for further research on this subject. The meeting with Henry II, Holy Roman Emperor in Regensburg on 6 April 1007 resulted in the latter declaring war on Boleslaw, after Wolinian and other delegates had reported that Boleslaw was preparing for war and had sought their support by offering money and making promises. Oskar Eggert and Filipowiak say that suggests that the town was independent in its policies by that time. Filipowiak further says that in the 11th century, Wolin became a \"save haven for Danish refugees, which in that period led to inner unrest and conflicts as well as pirate activities.\" Much of Wolin was destroyed in 1043 by Dano-Norwegian King Magnus the Good, who however failed to conquer its center. Also in the mid-11th century, export and wealth were greatly reduced, in part due to the breakdown of the Polish market. Yet the Wolinians retained their independence and continued to house refugees from the Danish opposition, causing Danish king Erik I Evergood to mount another campaign in 1098. In 1121/22, the Polish duke Bolesław III Wrymouth conquered the area along with the Duchy of Pomerania under Wartislaw I. Boleslaw aimed at Christianizing the area and in 1122 sent the Spanish eremite Bernard on a mission to Wolin. The inhabitants, reluctant to convert to a religion of a man who did not even wear shoes, beat him up badly and expelled him. With the approval of both Lothair III, Holy Roman Emperor, and Pope Callixtus II, Boleslaw initiated another mission of Saint Otto of Bamberg in 1124. When Otto, a respected and wealthy man accompanied by German and Polish clergymen and military units, arrived in Wolin, he had already successfully converted the Pyritz and Cammin areas. Yet, he was met with distrust, and the town's inhabitants finally gave in to convert to Christianity only if Otto managed to convert Szczecin, which the Wolinians assumed was unachievable. Yet, when Otto after two month work and threatening with another military intervention managed to convert Szczecin, he returned to Wolin and the Wolinians accepted conversion. Otto's second mission in 1128 was initiated by Holy Roman Emperor Lothair in 1128 after a pagan reaction. While this second mission was oriented more towards Western Pomerania, Otto also visited Wolin again. Wartislaw I, Duke of Pomerania supported and aided both missions. In 1140, Wolin was made the first episcopal see in Pomerania: Pope Innocent II founded the diocese by a papal bull of 14 October, and made Wolin's church of \"St. Adalbert\" its see. However, the see was moved to Grobe Abbey on the island of Usedom after 1150. At the same time Wolin economically decayed and was devastated by Danish expeditions, which contributed to the move of the episkopal see to Grobe. The Danish campaigns completely wiped out the town in the late 12th century. On the ruins of the early medieval town, a new town was founded and granted Lübeck Law. The town remained in the Duchy of Pomerania (which was a vassal of Denmark from 1185, and afterwards was within the Holy Roman Empire since 1227), passing with the duchy to the Swedish Crown following the Treaty of Stettin (1630), the Peace of Westphalia (1648) and the Treaty of Stettin (1653). Since the Treaty of Stockholm (Great Northern War) of 1720, it was incorporated into the Prussian Province of Pomerania. The town subsequently became part of the German Empire in 1871, then its successor states the Weimar Republic and the Third Reich. During World War II, the Germans operated a forced labour camp for French and Belgian prisoners of war from the Stalag II-B POW camp.

The southern parts of the town were ceded to Prussia by the 1720 Treaty of Stockholm, while a smaller section north of the Peene remained Swedish. It was damaged again during the Seven Years' War in the 1750s and '60s, with its fortifications being effectively dismantled in 1762. Sweden yielded its remaining part of the town in 1815, when all of Western Pomerania became part of the Prussian province of Pomerania. In the 19th century, Anklam was connected with Berlin and Stettin by rail and developed its manufacture of linen and woolen goods, leather, beer, and soap. Its 1871 population was 10,739, which had risen to 14,602 by the turn of the century. By the time of the First World War, it possessed a military school and developed iron foundries and sugar factories. In 1939 the Wehrmacht took over the military school and constructed a military prison on the grounds. Anklam was nearly completely destroyed by several bombing raids of the U.S. Air Force in 1943 and 1944 and in the last days of World War II, when the advancing Soviets burned and leveled most of the town. After Prussia and its Pomeranian province were dissolved and most of Pomerania was allocated to Poland under the terms of the Potsdam Conference, Anklam became part of the East German state of Mecklenburg-Vorpommern. That was soon to be dissolved, too, and Anklam was within the district of Neubrandenburg. The town was rebuilt in the rather uniform socialist style.

Although the settlement had only a few inhabitants, due to its central position it was often used as meeting place for officials of the Order. During the Thirteen Years' War, the castle was besieged on 24 May 1455 by troops of the Prussian Confederation under the command of Remschel von Krixen, but the garrison repulsed the attack. During the Horsemen's War in 1520, the castle was unsuccessfully besieged by troops of the Polish Kingdom, who devastated the settlement. Preußisch Eylau received its civic charter in 1585. In 1709–1711, the bubonic plague killed 2,212 inhabitants of the Eylau area. The Battle of Eylau (7–8 February 1807) during the Napoleonic Wars involved the French troops of Napoleon Bonaparte, the Russian troops of General Bennigsen, and the Prussian troops of General Anton Wilhelm von L'Estocq. Only 3 inhabitants of Eylau died in the battle, but 605 persons died due to hunger and diseases in 1807 (with the average death rate in \"normal\" years being around 80-90). Napoleon used the local courthouse as his headquarters in Eylau on 7–17 February 1807. On 1 April 1819, the town became the seat of the administrative district Preußisch Eylau (Kreis Pr. Eylau). In 1834, a Teachers' Seminary was founded, educating every East Prussian teacher until it was closed down in 1924. The town was connected to the railway on 2 September 1866. The town was occupied without a struggle by Russian troops on 27 August 1914, but these troops left on 3 September 1914 after massacring 65 civilians. After 1933, large barracks were built by the Wehrmacht, and in 1935 Infantry and Artillery units were stationed there.

These running times are equivalent because: We can achieve this bound as follows: first sort the edges by weight using a comparison sort in \"O\"(\"E\" log \"E\") time; this allows the step \"remove an edge with minimum weight from \"S\"\" to operate in constant time. Next, we use a disjoint-set data structure to keep track of which vertices are in which components. We place each vertex into its own disjoint set, which takes O(\"V\") operations. Finally, in worst case, we need to iterate through all edges, and for each edge we need to do two 'find' operations and possibly one union.

A variant of Kruskal's algorithm, named Filter-Kruskal, has been described by Osipov et al. and is better suited for parallelization. The basic idea behind Filter-Kruskal is to partition the edges in a similar way to quicksort and filter out edges that connect vertices of the same tree to reduce the cost of sorting. The following pseudocode demonstrates this. Filter-Kruskal lends itself better for parallelization as sorting, filtering, and partitioning can easily be performed in parallel by distributing the edges between the processors. Finally, other variants of a parallel implementation of Kruskal's algorithm have been explored.

Vast beds of sedimentary evaporite minerals, including halite, can result from the drying up of enclosed lakes, and restricted seas. Such salt beds may be hundreds of meters thick and underlie broad areas. Halite occurs at the surface today in playas in regions where evaporation exceeds precipitation such as in the salt flats of Badwater Basin in Death Valley National Park. In the United States and Canada extensive underground beds extend from the Appalachian basin of western New York through parts of Ontario and under much of the Michigan Basin. Other deposits are in Ohio, Kansas, New Mexico, Nova Scotia and Saskatchewan. The Khewra salt mine is a massive deposit of halite near Islamabad, Pakistan. Salt domes are vertical diapirs or pipe-like masses of salt that have been essentially \"squeezed up\" from underlying salt beds by mobilization due to the weight of overlying rock. Salt domes contain anhydrite, gypsum, and native sulfur, in addition to halite and sylvite. They are common along the Gulf coasts of Texas and Louisiana and are often associated with petroleum deposits. Germany, Spain, the Netherlands, Denmark, Romania and Iran also have salt domes. Salt glaciers exist in arid Iran where the salt has broken through the surface at high elevation and flows downhill. In all of these cases, halite is said to be behaving in the manner of a rheid. Unusual, purple, fibrous vein filling halite is found in France and a few other localities. Halite crystals termed \"hopper crystals\" appear to be \"skeletons\" of the typical cubes, with the edges present and stairstep depressions on, or rather in, each crystal face. In a rapidly crystallizing environment, the edges of the cubes simply grow faster than the centers. Halite crystals form very quickly in some rapidly evaporating lakes resulting in modern artifacts with a coating or encrustation of halite crystals. \"Halite flowers\" are rare stalactites of curling fibers of halite that are found in certain arid caves of Australia's Nullarbor Plain.

It is frequently used in food preservation methods across various cultures. Larger pieces can be ground in a salt mill or dusted over food from a shaker as finishing salt. Halite is also often used both residentially and municipally for managing ice. Because brine (a solution of water and salt) has a lower freezing point than pure water, putting salt or saltwater on ice that is below will cause it to melt — this effect is called freezing-point depression. It is common for homeowners in cold climates to spread salt on their sidewalks and driveways after a snow storm to melt the ice. It is not necessary to use so much salt that the ice is completely melted; rather, a small amount of salt will weaken the ice so that it can be easily removed by other means. Also, many cities will spread a mixture of sand and salt on roads during and after a snowstorm to improve traction. Using salt brine is more effective than spreading dry salt because moisture is necessary for the freezing-point depression to work and wet salt sticks to the roads better. Otherwise the salt can be wiped away by traffic. In addition to de-icing, rock salt is occasionally used in agriculture. An example of this would be inducing salt stress to suppress the growth of annual meadow grass in turf production. Other examples involve exposing weeds to salt water to dehydrate and kill them preventing them from affecting other plants. Salt is also used as a household cleaning product. Its coarse nature allows for its use in various cleaning scenarios including grease/oil removal, stain removal, and even dries out and hardens sticky spills for an easier clean. Some cultures, especially in Africa and Brazil, prefer a wide variety of different rock salts for different dishes. Pure salt is avoided as particular colors of salt indicates the presence of different impurities. Many recipes call for particular kinds of rock salt, and imported pure salt often has impurities added to adapt to local tastes. Historically, salt was used as a form of currency in barter systems and was exclusively controlled by authorities and their appointees. In some ancient civilizations the practice of salting the earth was done to make conquered land of an enemy infertile and inhospitable as an act of domination. One biblical reference to this practice is in Judges 9:45: \"he killed the people in it, pulled the wall down and sowed the site with salt.\" Polyhalite a mineral fertiliser, is not an NaCl-polymer but hydrated KCaMg-sulfate.", "section_level": 1}], "src_summary": "Halite ( or ), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl).

It is a member of the carotenoid family of compounds, and because it consists entirely of carbon and hydrogen, is also a carotene. Isolation procedures for lycopene were first reported in 1910, and the structure of the molecule was determined by 1931. In its natural, all-\"trans\" form, the molecule is long and straight, constrained by its system of 11 conjugated double bonds. Each extension in this conjugated system reduces the energy required for electrons to transition to higher energy states, allowing the molecule to absorb visible light of progressively longer wavelengths. Lycopene absorbs all but the longest wavelengths of visible light, so it appears red. Plants and photosynthetic bacteria naturally produce all-\"trans\" lycopene. When exposed to light or heat, lycopene can undergo isomerization to any of a number of \"cis\"-isomers, which have a bent rather than linear shape. Different isomers were shown to have different stabilities due to their molecular energy (highest stability: 5-cis ≥ all-trans ≥ 9-cis ≥ 13-cis > 15-cis > 7-cis > 11-cis: lowest). In human blood, various \"cis\"-isomers constitute more than 60% of the total lycopene concentration, but the biological effects of individual isomers have not been investigated. Carotenoids like lycopene are found in photosynthetic pigment-protein complexes in plants, photosynthetic bacteria, fungi, and algae. They are responsible for the bright orange–red colors of fruits and vegetables, perform various functions in photosynthesis, and protect photosynthetic organisms from excessive light damage. Lycopene is a key intermediate in the biosynthesis of carotenoids, such as beta-carotene, and xanthophylls. Dispersed lycopene molecules can be encapsulated into carbon nanotubes enhancing their optical properties.

Two molecules of this product are then condensed in a tail-to-tail configuration to give the 40-carbon phytoene, the first committed step in carotenoid biosynthesis.

Unlike other fruits and vegetables, where nutritional content such as vitamin C is diminished upon cooking, processing of tomatoes increases the concentration of bioavailable lycopene. Lycopene in tomato paste is up to four times more bioavailable than in fresh tomatoes. Processed tomato products such as pasteurized tomato juice, soup, sauce, and ketchup contain a higher concentration of bioavailable lycopene compared to raw tomatoes. Cooking and crushing tomatoes (as in the canning process) and serving in oil-rich dishes (such as spaghetti sauce or pizza) greatly increases assimilation from the digestive tract into the bloodstream.

This treaty, which created the Kingdom of Westphalia and the Duchy of Warsaw, completed Napoleon's humiliation of the Kingdom of Prussia, when it was deprived of one half of its dominions. This short-lived peace-treaty is also remarkable for quite another reason. Three days before its signing, Prussian queen Louise (1776–1810) tried to persuade Napoleon in a private conversation to ease his hard conditions on Prussia. Though unsuccessful, Louise's effort greatly endeared her to the Prussian people. Until 1945, a marble tablet marked the house in which King Frederick William III of Prussia and Queen Louise resided. Also, in the former Schenkendorf Platz was a monument to the poet Max von Schenkendorf (1783–1817), a native of Tilsit. During the 19th century when the Lithuanian language in Latin characters was banned within the Russian Empire, Tilsit was an important centre for printing Lithuanian books which then were smuggled by Knygnešiai to the Russian-controlled part of Lithuania. In general, Tilsit thrived and was an important Prussian town. By 1900 it had electric tramways and 34,500 inhabitants; a direct railway line linked it to Königsberg and Labiau and steamers docked there daily. It was occupied by Russian troops between 26 August 1914 and 12 September 1914 during World War I. The Act of Tilsit was signed here by leaders of the Lietuvininks in 1918. Hitler visited the town just before World War II, and a photo was taken of him on the famous bridge over the Memel River. Tilsit was occupied by the Red Army on January 20, 1945, and was annexed by the Soviet Union in 1945. The remaining Germans who had not evacuated were subsequently forcibly expelled and replaced with Soviet citizens. The town was renamed Sovetsk in honor of Soviet rule. Modern Sovetsk has sought to take advantage of Tilsit's rich traditions of cheese production (Tilsit cheese), but the new name (\"Sovetsky cheese\") has not inherited its predecessor's reputation. Since the dissolution of the Soviet Union in 1991, there has been some discussion about the possibility of restoring the town's original name, given its significance in Russian history. In 2010, the Kaliningrad Oblast's then-governor Georgy Boos of the ruling United Russia Party proposed restoring the original name and combining the town with the Nemen and Slavsk Districts to form a new Tilsit District. Boos emphasized that this move would stimulate development and economic growth, but that it could happen only through a referendum. The idea was opposed by the Communist Party of Russia. In particular, Igor Revin, the Kaliningrad Secretary of the Communist Party, accused Boos and United Russia of Germanophilia.

The algorithm may be modified to start with any particular vertex \"s\" by setting \"C\"[\"s\"] to be a number smaller than the other values of \"C\" (for instance, zero), and it may be modified to only find a single spanning tree rather than an entire spanning forest (matching more closely the informal description) by stopping whenever it encounters another vertex flagged as having no associated edge. Different variations of the algorithm differ from each other in how the set \"Q\" is implemented: as a simple linked list or array of vertices, or as a more complicated priority queue data structure. This choice leads to differences in the time complexity of the algorithm. In general, a priority queue will be quicker at finding the vertex \"v\" with minimum cost, but will entail more expensive updates when the value of \"C\"[\"w\"] changes.", "section_level": 1}, {"title": "Time complexity.", "content": "The time complexity of Prim's algorithm depends on the data structures used for the graph and for ordering the edges by weight, which can be done using a priority queue. The following table shows the typical choices: A simple implementation of Prim's, using an adjacency matrix or an adjacency list graph representation and linearly searching an array of weights to find the minimum weight edge to add, requires O(|V|) running time. However, this running time can be greatly improved further by using heaps to implement finding minimum weight edges in the algorithm's inner loop. A first improved version uses a heap to store all edges of the input graph, ordered by their weight. This leads to an O(|E| log |E|) worst-case running time. But storing vertices instead of edges can improve it still further. The heap should order the vertices by the smallest edge-weight that connects them to any vertex in the partially constructed minimum spanning tree (MST) (or infinity if no such edge exists). Every time a vertex \"v\" is chosen and added to the MST, a decrease-key operation is performed on all vertices \"w\" outside the partial MST such that \"v\" is connected to \"w\", setting the key to the minimum of its previous value and the edge cost of (\"v\",\"w\"). Using a simple binary heap data structure, Prim's algorithm can now be shown to run in time O(|E| log |V|) where |E| is the number of edges and |V| is the number of vertices. Using a more sophisticated Fibonacci heap, this can be brought down to O(|E| + |V| log |V|), which is asymptotically faster when the graph is dense enough that |E| is ω(|V|), and linear time when |E| is at least |V| log |V|. For graphs of even greater density (having at least |V| edges for some \"c\" > 1), Prim's algorithm can be made to run in linear time even more simply, by using a \"d\"-ary heap in place of a Fibonacci heap.", "section_level": 1}, {"title": "Proof of correctness.", "content": "Let \"P\" be a connected, weighted graph. At every iteration of Prim's algorithm, an edge must be found that connects a vertex in a subgraph to a vertex outside the subgraph. Since \"P\" is connected, there will always be a path to every vertex. The output \"Y\" of Prim's algorithm is a tree, because the edge and vertex added to tree \"Y\" are connected. Let \"Y\" be a minimum spanning tree of graph P. If \"Y\"=\"Y\" then \"Y\" is a minimum spanning tree. Otherwise, let \"e\" be the first edge added during the construction of tree \"Y\" that is not in tree \"Y\", and \"V\" be the set of vertices connected by the edges added before edge \"e\". Then one endpoint of edge \"e\" is in set \"V\" and the other is not. Since tree \"Y\" is a spanning tree of graph \"P\", there is a path in tree \"Y\" joining the two endpoints. As one travels along the path, one must encounter an edge \"f\" joining a vertex in set \"V\" to one that is not in set \"V\". Now, at the iteration when edge \"e\" was added to tree \"Y\", edge \"f\" could also have been added and it would be added instead of edge \"e\" if its weight was less than \"e\", and since edge \"f\" was not added, we conclude that Let tree \"Y\" be the graph obtained by removing edge \"f\" from and adding edge \"e\" to tree \"Y\". It is easy to show that tree \"Y\" is connected, has the same number of edges as tree \"Y\", and the total weights of its edges is not larger than that of tree \"Y\", therefore it is also a minimum spanning tree of graph \"P\" and it contains edge \"e\" and all the edges added before it during the construction of set \"V\". Repeat the steps above and we will eventually obtain a minimum spanning tree of graph \"P\" that is identical to tree \"Y\". This shows \"Y\" is a minimum spanning tree.

He writes,\" The modern mind has not made up its mind whether it should be Christian or pagan, it sees with one eye of faith and one of reason. Hence its vision is necessarily dim in comparison with either Greek or biblical thinking.\" The modern view is progressive, which is to say that it believes that the trajectory of history is moving towards a fulfillment in the bettering of the world by rational and technological means. Löwith believes that the modern view is a sort of Christian \"heresy\" insofar that is depends on the theology that history has a linear movement, in contrast to Greek pagan cyclical view of history. In this critique Löwith is prophetic in the sense that he anticipates the way post-secular theologians will pick up a similar critique of modernity in the 1990s (such is the case in the Radical Orthodox movement). The modern historical consciousness is, according to Löwith, derived from Christianity. But, this is mistaken because Christians are not a historical people, as their view of the world is based on faith. This explains the tendency in history (and philosophy) to see an eschatological view of human progress. Löwith traces the \"regression\" of history as opposed to a progression through famous western philosophers and historians. Whereas most genealogies begin from the most antique to the modern, Löwith begins with the most current. He moves from Burckhardt, to Marx, to Hegel, Voltaire, Vico, Bossuet, Augustine, Orosius, and others. He argues that the closer we get to the Biblical vision of history, \" I cannot discover the slightest hint of a \"philosophy of history\". By this he means that a truly theological view of history is not movement to an immanent end, but a transcendent eschatological hope in the consummation of the world. It is not a \"philosophy\" or attempt to systematize the movement of history. This point is clear in the epilogue of \"Meaning in History\" where he says, \" The attempt at elucidation of the dependence of the philosophy of history on the eschatological history of fulfillment and salvation does not solve the problem of historical thinking.\" Here he seems to argue that like the progressive view any theological view that tries to equate the happenings of history with God's action is inadequate, which reveals his true argument: We cannot understand the happening of history by reason. Returning to the idea that Löwith like Barth and others was trying to rethink Christian faith in light of the crisis of world war, Lowith's real concern is the relationship between faith and reason or more specifically faith and history. He writes,\"The Christian hope is not a worldly desire and expectation that something will probably happen but a cast of mind based on an unconditional faith in God's redemptive purpose. Genuine hope is, therefore, as free and absolute as the act of faith itself. Both hope and faith are Christian virtues of Grace. The reasons for such an unconditional hope and faith cannot rest on rational calculation of their reasonableness. Hence hope can never be refuted by so-called facts; it can neither be assured no discredited by an established experience.\" His analysis of the relationship between faith and the observable events of history is one of absolute disconnect, which is an idea he seems to adopt from Kierkegaard's similar argument in \"Practice in Christianity\". Lowith's answer to the change of modernity is to say that Christianity has nothing at all to do with history or reason, rather it is about being given faith, which becomes hope in the God-man. He writes,\" The question is therefore not the justification of absolute hope and faith by their relative reasonableness, but whether such an unconditional hope and faith can be put into man instead of God and the God-man. Hope is justified only by faith which justifies itself.\" So, whereas the \"liberal\" Christianity of his contemporaries tried to accommodate or assimilate faith with reason, Lowith maintains that faith justifies itself.", "section_level": 2}], "src_summary": "Karl Löwith (9 January 1897 – 26 May 1973) was a German philosopher in the phenomenological tradition.

Some of its affluences are Garzan, Anbarçayi, Batman, and the Great and the Little Zab. Close to its confluence with the Euphrates, the Tigris splits into several channels. First, the artificial Shatt al-Hayy branches off, to join the Euphrates near Nasiriyah. Second, the Shatt al-Muminah and Majar al-Kabir branch off to feed the Central Marshes. Further downstream, two other distributary channels branch off (the Al-Musharrah and Al-Kahla), to feed the Hawizeh Marshes. The main channel continues southwards and is joined by the Al-Kassarah, which drains the Hawizeh Marshes. Finally, the Tigris joins the Euphrates near al-Qurnah to form the Shatt-al-Arab. According to Pliny and other ancient historians, the Euphrates originally had its outlet into the sea separate from that of the Tigris. Baghdad, the capital of Iraq, stands on the banks of the Tigris. The port city of Basra straddles the Shatt al-Arab.

This was held up in contrast to what was perceived to be the alienating effects of industrial labor. These activities were called \"crafts\" because originally many of them were professions under the guild system. Adolescents were apprenticed to a master craftsman and refined their skills over a period of years in exchange for low wages. By the time their training was complete, they were well equipped to set up in trade for themselves, earning their living with the skill that could be traded directly within the community, often for goods and services. The Industrial Revolution and the increasing mechanization of production processes gradually reduced or eliminated many of the roles professional craftspeople played, and today many handicrafts are increasingly seen, especially when no longer the mainstay of a formal vocational trade, as a form of hobby, folk art and sometimes even fine art. The term \"handicrafts\" can also refer to the products themselves of such artisanal efforts, that require specialized knowledge, maybe highly technical in their execution, require specialized equipment and/or facilities to produce, involve manual labor or a blue-collar work ethic, are accessible to the general public, and are constructed from materials with histories that exceed the boundaries of Western \"fine art\" tradition, such as ceramics, glass, textiles, metal and wood. These products are produced within a specific community of practice, and while they mostly differ from the products produced within the communities of art and design, the boundaries often overlap, resulting in hybrid objects.

In Dresden Schütz sowed the seeds of what is now the Sächsische Staatskapelle Dresden, but left there on several occasions; in 1628 he went to Venice again, where he met and studied with Claudio Monteverdi. In 1633 he was invited to Copenhagen to compose the music for wedding festivities there, eventually returning to Dresden in 1635. He again conducted an extended visit to Denmark in 1641, due to the devastation of the Electoral court. The Thirty Years' War ended in 1648, and he again became more active in Dresden. In 1655, the year that his daughter Euphrosyne died, he accepted an \"ex officio\" post as Kapellmeister at Wolfenbüttel. His Dresden compositions during the Thirty Years' War were, by necessity of the times, smaller scale than the oft-massive works before, although this period produced much of his most charming music.

Additionally, the influence of the Netherlandish composers of the 16th century is prominent in his work. His best known works are in the field of sacred music, ranging from solo voice with instrumental accompaniment to a cappella choral music. Representative works include his Psalmen Davids\" (Psalms of David, Opus 2), Cantiones sacrae\" (Opus 4), three books of \"Symphoniae sacrae\", \"Die sieben Worte Jesu Christi am Kreuz\" (The seven words of Jesus Christ on the Cross), three Passion settings and the Christmas Story. Schütz's music, while starting off in the most progressive styles early in his career, eventually grew into a style that is simple and almost austere, culminating with his late Passion settings. Practical considerations were certainly responsible for part of this change: the Thirty Years' War had devastated the musical infrastructure of Germany, and it was no longer practical or even possible to put on the gigantic works in the Venetian style which marked his earlier period. The unique composition \"Es steh Gott auf\" (SWV 356) is in many respects comparable to Monteverdi. His funeral music \"Musikalische Exequien\" (1636) for his noble friend Heinrich Posthumus of Reuss is considerad a masterpiece, and is known today as the first German Requiem. Schütz was equally fluent in his Latin or Germanic styles. Schütz was one of the last composers to write in a modal style. His harmonies often result from the contrapuntal alignment of voices rather than from any sense of \"harmonic motion\"; contrastingly, much of his music shows a strong tonal pull when approaching cadences. His music includes a great deal of imitation, but structured in such a way that the successive voices do not necessarily enter after the same number of beats or at predictable intervallic distances. This contrasts sharply with the manner of his contemporary Samuel Scheidt, whose counterpoint usually flows in regularly spaced entries. Schütz's writing often includes intense dissonances caused by the contrapuntal motion of voices moving in correct individual linear motion, but resulting in startling harmonic tension. Above all, his music displays extreme sensitivity to the accents and meaning of the text, which is often conveyed using special technical figures drawn from \"musica poetica,\" themselves drawn from or created in analogy to the verbal figures of classical rhetoric. However, as noted above, the composer's style became simpler in his later works, which make less frequent use of the kind of distantly related chords and licences found in such pieces as \"Was hast du verwirket\" (SWV 307) from \"Kleine geistliche Konzerte II\". Beyond the early book of madrigals, almost no secular music by Schütz has survived, save for a few domestic songs (\"arien\") and occasional commemorative items (such as \"Wie wenn der Adler sich aus seiner Klippe schwingt\" (SWV 434), and no purely instrumental music at all (unless one counts the short instrumental movement entitled \"sinfonia\" that encloses the dialogue of \"Die sieben Worte\"), even though he had a reputation as one of the finest organists in Germany. Schütz was of great importance in bringing new musical ideas to Germany from Italy, and thus had a large influence on the German music which was to follow. The style of the North German organ school derives largely from Schütz (as well as from the Dutchman Jan Pieterszoon Sweelinck); a century later this music was to culminate in the work of J.S. Bach.

For some people, letters were seen as a written performance. For others, it was not only seen as a performance but also as a way of communication and a method of gaining feedback. Letters make up several of the books of the Bible. Archives of correspondence, whether for personal, diplomatic, or business reasons, serve as primary sources for historians.

For example, the development of the telegraph drastically shortened the time taken to send a communication, by sending it between distant points as an electrical signal. At the telegraph office closest to the destination, the signal was converted back into writing on paper and delivered to the recipient.

In 1225 written records first mentioned the town; Kamenz became an independent city in 1319, when Emperor Louis IV enfeoffed the West Lusatian lands to the Luxembourg king John of Bohemia. In 1346, the citizens joined the Lusatian League for protection against robber barons and to maintain public peace (\"Landfrieden\"). The town was nevertheless besieged and finally occupied by Hussite forces in 1429, who also devastated the nearby town of Wittichenau before they marched against Bautzen. In 1493 King Vladislaus II of Bohemia had a Franciscan monastery established north of the Kamenz town walls, dedicated to Saint Anne in 1512. Kamenz citizens officially turned Protestant in 1536. In the Schmalkaldic War of 1546/47, the Upper Lusatian towns refused to support the troops of the Habsburg emperor Ferdinand I against the Protestant princes and were penalised with the loss of numerous privileges. The Franciscan convent finally dissolved in 1564. According to the 1635 Peace of Prague, the Lusatias passed from the Bohemian Crown to the Electorate of Saxony.

The first philatelist is considered to be a postmaster going by Mansen, who lived in Paris, and in 1855 had sold his collection, which contained almost all the postage stamps issued by that time. The stamp merchant and second-hand book dealer Edard de Laplante bought it, recognizing the definitive collector's worth of the postage stamp. Due to the boom in popularity and news of this transaction, stamp merchants like Laplante began to emerge. Towards the end of the 19th century stamp collecting reached hundreds of thousands of people of all classes. Even some states had collections of postage stamps, for example, England, Germany, France, Bavaria, and Bulgaria). In countries who held national collections, museums were built to dedicate that nation's history with philately, and the first such appeared in Germany, France, and Bulgaria. Allegedly, the first of these museums housed the collection of the British Museum, curated by MP Tapling and bequeathed to the Museum in 1891. The Museum für Kommunikation Berlin also had an extensive collection of stamps. The largest collection of the time belonged to Baron Philipp von Ferrary in Paris.

Stamp Day is a memorial day established by the postal administration of a country and annually celebrated, which is designed to attract public attention to, popularize the use of, and expand the reach of postal correspondence, and contribute to the development of philately. In 1968, Cuba dedicated a postage stamp for Stamp Day with an image of G. Sciltian's \"El filatelista\".

Decades later, the BLU-82 was used in Afghanistan in November 2001 against the Taliban. Its success as a weapon of intimidation led to the decision to develop the MOAB. Pentagon officials suggested MOAB might be used as an anti-personnel weapon, as part of the \"shock and awe\" strategy integral to the 2003 invasion of Iraq. GBU-43s are delivered from C-130 cargo aircraft, inside which they are carried on cradles resting on airdrop platforms. The bombs are dropped by deploying drogue parachutes, which also extract the cradle and platform from the aircraft. Shortly after launch the drogues are released and the bomb falls without the use of a retarding parachute. GPS satellite-guidance is used to guide bombs to their targets. The MOAB is not a penetrator weapon and is primarily an air burst ordnance intended for soft to medium surface targets covering extended areas and targets in a contained environment such as a deep canyon or within a cave system. High altitude carpet-bombing with much smaller bombs delivered via heavy bombers such as the B-52, B-2, or the B-1 is also highly effective at covering large areas. The MOAB is designed to be used against a specific target, and cannot by itself replicate the effects of a typical heavy bomber mission. During the Vietnam War's Operation Arc Light program, for example, the United States Air Force sent B-52s on well over 10,000 bombing raids, each usually carried out by two groups of three aircraft. A typical mission dropped 168 tons of ordnance, pounding an area 1.5 by 0.5 miles with an explosive force equivalent to 10 to 17 MOABs.

Since 2003, 15 MOABs have been manufactured at the McAlester Army Ammunition Plant in McAlester, Oklahoma. The Air Force has said the MOAB has a unit price of $170,000, but this is a historical unit cost made in the mid-2000s and various factors of the bomb's atypical development process have made exact cost estimation difficult. The Air Force Research Lab generated the value based on already existing parts such as bomb casing and metals, and since the bomb was built in-house by the service they did not pay for outside research or have standard procurement costs associated with it. MOAB was a \"crash project\" developed for use against an adversary with uncertain tactics on unfamiliar terrain, and so was an effort to meet an urgent need rather than a formal program.

Pfleumer's invention used a ferric oxide () powder coating on a long strip of paper. This invention was further developed by the German electronics company AEG, which manufactured the recording machines and BASF, which manufactured the tape. In 1933, working for AEG, Eduard Schuller developed the ring-shaped tape head. Previous head designs were needle-shaped and tended to shred the tape. Another important discovery made in this period was the technique of AC biasing, which improved the fidelity of the recorded audio signal by increasing the effective linearity of the recording medium. Due to the escalating political tensions, and the outbreak of World War II, these developments in Germany were largely kept secret. Although the Allies knew from their monitoring of Nazi radio broadcasts that the Germans had some new form of recording technology, its nature was not discovered until the Allies acquired German recording equipment as they invaded Europe at the end of the war. It was only after the war that Americans, particularly Jack Mullin, John Herbert Orr, and Richard H. Ranger, were able to bring this technology out of Germany and develop it into commercially viable formats. Bing Crosby, an early adopter of the technology, made a large investment in the tape hardware manufacturer Ampex.

Existing audio tape recorders could not practically capture a video signal. Many set to work on resolving this problem. Jack Mullin (working for Bing Crosby) and the BBC both created crude working systems that involved moving the tape across a fixed tape head at very high speeds. Neither system saw much use. It was the team at Ampex, led by Charles Ginsburg, that made the breakthrough of using a spinning recording head and normal tape speeds to achieve a very high head-to-tape speed that could record and reproduce the high bandwidth signals of video. The Ampex system was called Quadruplex and used tape, mounted on reels like audio tape, which wrote the signal in what is now called \"transverse scan\". Later improvements by other companies, particularly Sony, led to the development of helical scan and the enclosure of the tape reels in an easy-to-handle videocassette cartridge.

The system's UNISERVO I tape drive used a thin strip of one half inch (12.65 mm) wide metal, consisting of nickel-plated bronze (called Vicalloy). Recording density was 100 characters per inch (39.37 characters/cm) on eight tracks. Early IBM 7 track tape drives were floor-standing and used vacuum columns to mechanically buffer long U-shaped loops of tape. The two tape reels visibly fed tape through the columns, intermittently spinning 10.5 inch open reels in rapid, unsynchronized bursts, resulting in visually striking action. Stock shots of such vacuum-column tape drives in motion were widely used to represent mainframe computers in movies and television. Most modern magnetic tape systems use reels that are much smaller than the 10.5 inch open reels and are fixed inside a cartridge to protect the tape and facilitate handling. Many late 1970s and early 1980s home computers used Compact Cassettes, encoded with the Kansas City standard, or alternate encodings. Modern cartridge formats include LTO, DLT, and DAT/DDC. Tape remains a viable alternative to disk in some situations due to its lower cost per bit. This is a large advantage when dealing with large amounts of data. Though the areal density of tape is lower than for disk drives, the available surface area on a tape is far greater. The highest capacity tape media are generally on the same order as the largest available disk drives (about 5 TB in 2011). Tape has historically offered enough advantage in cost over disk storage to make it a viable product, particularly for backup, where media removability is necessary. Tape has the benefit of a comparatively long duration during which the media can be guaranteed to retain the data stored on the media. Fifteen (15) to thirty (30) years of archival data storage is cited by manufacturers of modern data tape such as Linear Tape-Open media. In 2002, Imation received a US$11.9 million grant from the U.S. National Institute of Standards and Technology for research into increasing the data capacity of magnetic tape. In 2014, Sony and IBM announced that they had been able to record 148 gigabits per square inch with magnetic tape media developed using a new vacuum thin-film forming technology able to form extremely fine crystal particles, allowing true tape capacity of 185 TB.", "section_level": 1}], "src_summary": "Magnetic tape is a medium for magnetic recording, made of a thin, magnetizable coating on a long, narrow strip of plastic film.

Carthage, stripped of allies and territory (Sicily, Sardinia, Hispania), was suffering under a large indemnity of 200 silver talents to be paid every year for 50 years. According to Appian, the senator Cato the Elder usually finished his speeches on any subject in the Senate with the phrase \"ceterum censeo Carthaginem esse delendam\", which means \"Moreover, I am of the opinion that Carthage ought to be destroyed\". Cicero attributed a similar statement to Cato in his dialogue \"De Senectute\". He was opposed by the senator Publius Cornelius Scipio Nasica Corculum, who favoured a different course that would not destroy Carthage, and who usually prevailed in the debates. The peace treaty at the end of the Second Punic War required that all border disputes involving Carthage be arbitrated by the Roman Senate and required Carthage to get explicit Roman approval before going to war. As a result, in the 50 intervening years between the Second and Third Punic War, Carthage had to take all border disputes with Rome's ally Numidia to the Roman Senate, where they were decided almost exclusively in the latter's favour. In 151 BC, the Carthaginian debt to Rome was fully repaid, meaning that, in Punic eyes, the treaty was now expired, though not so according to the Romans, who instead viewed the treaty as a permanent declaration of Carthaginian subordination to Rome, akin to the Roman treaties with its Italian allies. Moreover, the retirement of the indemnity removed one of the main incentives the Romans had to keep the peace with Carthage – there were no further payments that might be interrupted. The Romans had other reasons to conquer Carthage and her remaining territories. By the middle of the 2nd century BC, the population of the city of Rome was about 400,000 and rising. Feeding the growing populace was becoming a major challenge. The farmlands surrounding Carthage represented the most productive, most accessible and perhaps the most easily obtainable agricultural lands not yet under Roman control.", "section_level": 1}, {"title": "Course of the war.", "content": "In 151 BC Numidia launched another border raid on Carthaginian soil, besieging the Punic town of Oroscopa, and Carthage launched a large military expedition (25,000 soldiers) to repel the Numidian invaders. However, Carthage suffered a military defeat and was charged with another fifty year debt to Numidia. Immediately after, however, Rome showed displeasure with Carthage's decision to wage war against its neighbour without Roman consent. In 149 BC, Rome declared war against Carthage. The Carthaginians made a series of attempts to appease Rome, and received a promise that if three hundred children of well-born Carthaginians were sent as hostages to Rome the Carthaginians would keep the rights to their land and self-government. Even after this was done the allied Punic city of Utica defected to Rome, and a Roman army of 80,000 men gathered there. The consuls then demanded that Carthage hand over all weapons and armor. After those had been handed over, Rome additionally demanded that the Carthaginians move at least 16 kilometres inland, while the city was to be burned. When the Carthaginians learned of this, they abandoned negotiations and the city was immediately besieged, beginning the Third Punic War. After the main Roman expedition landed at Utica, consuls Manius Manilius and Lucius Marcius Censorius launched a two-pronged attack on Carthage, but were eventually repulsed by the army of the Carthaginian Generals Hasdrubal the Boeotarch and Himilco Phameas. Censorius lost more than 500 men when they were surprised by the Carthaginian cavalry while collecting timber around the Lake of Tunis. A worse disaster fell upon the Romans when their fleet was set ablaze by fire ships which the Carthaginians released upwind. Manilius was replaced by consul Calpurnius Piso Caesonius in 149 after a severe defeat of the Roman army at Nepheris, a Carthaginian stronghold south of the city. Scipio Aemilianus's intervention saved four cohorts trapped in a ravine. Nepheris eventually fell to Scipio in the winter of 147–146. In the autumn of 148, Piso was beaten back while attempting to storm the city of Aspis, near Cape Bon. Undeterred, he laid siege to the town of Hippagreta in the north, but his army was unable to defeat the Punics there before winter and had to retreat. When news of these setbacks reached Rome, he was replaced as consul by Scipio Aemilianus. The Carthaginians endured the siege, starting 149 BC to the spring of 146 BC, when Scipio Aemilianus successfully assaulted the city. Though the Punic citizens offered strong resistance, they were gradually pushed back by the overwhelming Roman military force and destroyed.", "section_level": 1}, {"title": "Aftermath.", "content": "Many Carthaginians died from starvation during the later part of the siege, while many others died in the final six days of fighting. When the war ended, the remaining 50,000 Carthaginians, a small part of the original pre-war population, were sold into slavery by the victors. Carthage was systematically burned for 17 days; the city's walls and buildings were utterly destroyed. The remaining Carthaginian territories were annexed by Rome and reconstituted to become the Roman province of Africa. The notion that Roman forces then sowed the city with salt to ensure that nothing would grow there again is almost certainly a 19th-century invention. Contemporary accounts show that the land surrounding Carthage was declared \"ager publicus\" and that it was shared between local farmers, and Roman and Italian ones. North Africa soon became a vital source of grain for the Romans. Roman Carthage was the main hub transporting these supplies to the capital. Numerous significant Punic cities, such as those in Mauretania, were taken over and rebuilt by the Romans. Examples of these rebuilt cities are Volubilis, Chellah and Arambys. Volubilis, for example, was an important Roman town situated near the westernmost border of Roman conquests. It was built on the site of the previous Punic settlement, but that settlement overlies an earlier neolithic habitation. Utica, the Punic city which changed loyalties at the beginning of the siege, became the capital of the Roman province of Africa.

Michel Foucault translated it into French. However, the term first came into general use following the publication of a series of papers by Zellig Harris from 1952 reporting on work from which he developed transformational grammar in the late 1930s. Formal equivalence relations among the sentences of a coherent discourse are made explicit by using sentence transformations to put the text in a canonical form. Words and sentences with equivalent information then appear in the same column of an array. This work progressed over the next four decades (see references) into a science of sublanguage analysis (Kittredge & Lehrberger 1982), culminating in a demonstration of the informational structures in texts of a sublanguage of science, that of Immunology, (Harris et al. 1989) and a fully articulated theory of linguistic informational content (Harris 1991). During this time, however, most linguists ignored such developments in favor of a succession of elaborate theories of sentence-level syntax and semantics. In January 1953, a linguist working for the American Bible Society, James A. Lauriault/Loriot, needed to find answers to some fundamental errors in translating Quechua, in the Cuzco area of Peru. Following Harris's 1952 publications, he worked over the meaning and placement of each word in a collection of Quechua legends with a native speaker of Quechua and was able to formulate discourse rules that transcended the simple sentence structure. He then applied the process to Shipibo, another language of Eastern Peru. He taught the theory at the Summer Institute of Linguistics in Norman, Oklahoma, in the summers of 1956 and 1957 and entered the University of Pennsylvania to study with Harris in the interim year. He tried to publish a paper \"Shipibo Paragraph Structure\", but it was delayed until 1970 (Loriot & Hollenbach 1970). In the meantime, Kenneth Lee Pike, a professor at University of Michigan, Ann Arbor, taught the theory, and one of his students, Robert E. Longacre developed it in his writings. Harris's methodology disclosing the correlation of form with meaning was developed into a system for the computer-aided analysis of natural language by a team led by Naomi Sager at NYU, which has been applied to a number of sublanguage domains, most notably to medical informatics.

In this context, the term 'discourse' no longer refers to formal linguistic aspects, but to institutionalized patterns of knowledge that become manifest in disciplinary structures and operate by the connection of knowledge and power. Since the 1970s, Foucault's works have had an increasing impact especially on discourse analysis in the social sciences. Thus, in modern European social sciences, one can find a wide range of different approaches working with Foucault's definition of discourse and his theoretical concepts. Apart from the original context in France, there is, at least since 2005, a broad discussion on socio-scientific discourse analysis in Germany. Here, for example, the sociologist Reiner Keller developed his widely recognized 'Sociology of Knowledge Approach to Discourse (SKAD)'. Following the sociology of knowledge by Peter L. Berger and Thomas Luckmann, Keller argues, that our sense of reality in everyday life and thus the meaning of every object, actions and events are the product of a permanent, routinized interaction. In this context, SKAD has been developed as a scientific perspective that is able to understand the processes of 'The Social Construction of Reality' on all levels of social life by combining Michel Foucault's theories of discourse and power with the theory of knowledge by Berger/Luckmann. Whereas the latter primarily focus on the constitution and stabilisation of knowledge on the level of interaction, Foucault's perspective concentrates on institutional contexts of the production and integration of knowledge, where the subject mainly appears to be determined by knowledge and power.

For instance, many types of discourse begin with some kind of global'summary', in titles, headlines, leads, abstracts, and so on.

After his father died of tuberculosis, Keller's family lived in constant poverty, and, because of Keller's difficulties with his teachers, in continual disagreement with school authorities. Keller later gave a good rendering of his experiences in this period in his long novel, \"Der grüne Heinrich\" (1850–55; 2nd version, 1879). His mother seems to have brought him up in as carefree a condition as possible, sparing for him from her scanty meals, and allowing him the greatest possible liberty in the disposition of his time, the choice of a calling, etc. With some changes, a treatment of her relations to him may be found in his short story, “Frau Regel Amrain und ihr jüngster” (in the collection \"Die Leute von Seldwyla\").", "section_level": 1}, {"title": "Career.", "content": "Keller's first true passion was painting. Expelled in a political mix-up from the \"Industrieschule\" in Zürich, he became an apprentice in 1834 to the landscape painter Steiger and in 1837 to the watercolourist Rudolf Meyer (1803–1857). In 1840, he went to Munich (Bavaria) to study art for a time at the Royal Academy of Fine Arts. Keller returned to Zürich in 1842 and, although possessing artistic talent, took up writing. He published his first poems, \"Gedichte\", in 1846. Jacob Wittmer Hartmann characterizes these six years at Zürich (1842–48) as a time of almost total inactivity, when Keller inclined strongly toward radicalism in politics, and was also subject to much temptation and indulged himself. From 1848 to 1850 he studied at the University of Heidelberg. There he came under the influence of the philosopher Feuerbach, and extended his radicalism also to matters of religion. From 1850 to 1856, he worked in Berlin. Hartmann claims it was chiefly this stay in Berlin which molded Keller's character into its final shape, toned down his rather bitter pessimism to a more moderate form, and prepared him (not without the privations of hunger), in the whirl of a large city, for an enjoyment of the more restricted pleasures of his native Zürich. It was in Berlin that he turned definitely away from other pursuits and took up literature as a career. In this period, Keller published the semi-autobiographical novel \"Der grüne Heinrich\" (\"Green Henry\"). It is the most personal of all his works. Under the influence of Jean-Jacques Rousseau's doctrine of a return to nature, this book was at first intended to be a short narrative of the collapse of the life of a young artist. It expanded as its composition progressed into a huge work drawing on Keller's youth and career (or more precisely \"non-career\") as a painter up to 1842. Its reception by the literary world was cool, but the second version of 1879 is a rounded and satisfying artistic product. He also published his first collection of short stories, \"Die Leute von Seldwyla\" (\"The People of Seldwyla\"). It contains five stories averaging 60 pages each: “Pankraz der Schmoller,” “Frau Regel Amrain und ihr jüngster,” “Die drei gerechten Kammacher,” “Romeo und Julia auf dem Dorfe,” and “Spiegel das Kätzchen.” Hartmann characterizes two of the stories in \"Die Leute von Seldwyla\" as immortal: “Die drei gerechten Kammacher” he views as the most satyric and scorching attack on the sordid petit bourgeois morality ever penned by any writer, and “Romeo und Julia auf dem Dorfe” as one of the most pathetic tales in literature (Shakespeare's \"Romeo and Juliet\" plot in a Swiss village setting). Keller returned again to Zürich and became the \"First Official Secretary\" of the Canton of Zürich (\"Erster Zürcher Staatsschreiber\") in 1861. The routine duties of this position were a sort of fixed point about which his artistic activities could revolve, but Hartmann opines that he produced little of permanent value in these years. In 1872, Keller published \"Seven Legends\" (\"Sieben Legenden\"), which dealt with the early Christian era. After 15 years at this post, he was retired in 1876, and began a period of literary activity that was to last to his death, living the life of an old bachelor with his sister Regula as his housekeeper.

Thus, when a proton encounters an antiproton, one of its quarks, usually a constituent valence quark, may annihilate with an antiquark (which more rarely could be a sea quark) to produce a gluon, after which the gluon together with the remaining quarks, antiquarks, and gluons will undergo a complex process of rearrangement (called hadronization or fragmentation) into a number of mesons, (mostly pions and kaons), which will share the total energy and momentum. The newly created mesons are unstable, and unless they encounter and interact with some other material, they will decay in a series of reactions that ultimately produce only photons, electrons, positrons, and neutrinos. This type of reaction will occur between any baryon (particle consisting of three quarks) and any antibaryon consisting of three antiquarks, one of which corresponds to a quark in the baryon.

Antiprotons can and do annihilate with neutrons, and likewise antineutrons can annihilate with protons, as discussed below. Reactions in which proton-antiproton annihilation produces as many as nine mesons have been observed, while production of thirteen mesons is theoretically possible. The generated mesons leave the site of the annihilation at moderate fractions of the speed of light, and decay with whatever lifetime is appropriate for their type of meson. Similar reactions will occur when an antinucleon annihilates within a more complex atomic nucleus, save that the resulting mesons, being strongly interacting, have a significant probability of being absorbed by one of the remaining \"spectator\" nucleons rather than escaping. Since the absorbed energy can be as much as ~2 GeV, it can in principle exceed the binding energy of even the heaviest nuclei. Thus, when an antiproton annihilates inside a heavy nucleus such as uranium or plutonium, partial or complete disruption of the nucleus can occur, releasing large numbers of fast neutrons.

In 2012, the CERN laboratory in Geneva announced the discovery of the Higgs in the debris from proton-proton collisions at the Large Hadron Collider (LHC).

Weierstrass was the son of Wilhelm Weierstrass, a government official, and Theodora Vonderforst. His interest in mathematics began while he was a gymnasium student at the in Paderborn. He was sent to the University of Bonn upon graduation to prepare for a government position. Because his studies were to be in the fields of law, economics, and finance, he was immediately in conflict with his hopes to study mathematics. He resolved the conflict by paying little heed to his planned course of study, but continued private study in mathematics. The outcome was to leave the university without a degree. After that he studied mathematics at the Münster Academy (which was even at this time very famous for mathematics) and his father was able to obtain a place for him in a teacher training school in Münster. Later he was certified as a teacher in that city. During this period of study, Weierstrass attended the lectures of Christoph Gudermann and became interested in elliptic functions. In 1843 he taught in Deutsch Krone in West Prussia and since 1848 he taught at the Lyceum Hosianum in Braunsberg. Besides mathematics he also taught physics, botany, and gymnastics. Weierstrass may have had an illegitimate child named Franz with the widow of his friend Carl Wilhelm Borchardt. After 1850 Weierstrass suffered from a long period of illness, but was able to publish mathematical articles that brought him fame and distinction. The University of Königsberg conferred an honorary doctor's degree on him on 31 March 1854. In 1856 he took a chair at the Gewerbeinstitut, which later became the Technical University of Berlin. In 1864 he became professor at the Friedrich-Wilhelms-Universität Berlin, which later became the Humboldt Universität zu Berlin. At the age of fifty-five, Weierstrass met Sofia Kovalevsky whom he tutored privately after failing to secure her admission to the University. They had a fruitful intellectual, but troubled personal relationship that \"far transcended the usual teacher-student relationship\".

Delta-epsilon proofs are first found in the works of Cauchy in the 1820s. Cauchy did not clearly distinguish between continuity and uniform continuity on an interval. Notably, in his 1821 \"Cours d'analyse,\" Cauchy argued that the (pointwise) limit of (pointwise) continuous functions was itself (pointwise) continuous, a statement interpreted as being incorrect by many scholars. The correct statement is rather that the \"uniform\" limit of continuous functions is continuous (also, the uniform limit of uniformly continuous functions is uniformly continuous). This required the concept of uniform convergence, which was first observed by Weierstrass's advisor, Christoph Gudermann, in an 1838 paper, where Gudermann noted the phenomenon but did not define it or elaborate on it. Weierstrass saw the importance of the concept, and both formalized it and applied it widely throughout the foundations of calculus.

In the 1990s and onward, with personal computers, better screens, and the Web, it makes sense to consider only \"content\", independent of media. This \"content-oriented identification\" of serials was a repressed demand during a decade, but no ISSN update or initiative occurred. A natural extension for ISSN, the unique-identification of the articles in the serials, was the main demand application. An alternative serials' contents model arrived with the indecs Content Model and its application, the digital object identifier (DOI), an ISSN-independent initiative, consolidated in the 2000s.

His grandfather had been forced to relocate to Siberia for his role in the 1905 Russian Revolution. Alexei was the eighth of nine surviving children born to Yevdokia and Arkhip. His father was an electrician and miner. In 1936, his father was arrested and declared an \"enemy of the people\". Leonov wrote in his autobiography: \"He was not alone: many were being arrested. It was part of a conscientious drive by the authorities to eradicate anyone who showed too much independence or strength of character. These were the years of Stalin's purges. Many disappeared into remote gulags and were never seen again.\" The family moved in with one of his married sisters in Kemerovo. His father rejoined the family in Kemerovo after he was released. He was compensated for his wrongful imprisonment. Leonov used art as a way to provide more food for the family. He began his art career by drawing flowers on ovens and later painted landscapes on canvasses. The Soviet government encouraged its citizens to move to Soviet-occupied Prussia, so in 1948 his family relocated to Kaliningrad. Leonov graduated from secondary school (No. 21) in 1953. He applied to the Academy of Arts in Riga, Latvia, but decided not to attend due to the high tuition costs. Leonov decided to join a Ukrainian preparatory flying school in Kremenchug; he made his first solo flight in May 1955. While indulging in his passion for art by studying part-time in Riga, Leonov started an advanced two-year course to become a fighter pilot at the Chuguev Higher Air Force Pilots School in the Ukrainian SSR. On 30 October 1957, Leonov graduated with an honours degree and was commissioned a lieutenant in the 113th Parachute Aviation Regiment, part of the 10th Engineering Aviation Division of the 69th Air Army in Kiev.

As most cosmonauts, Leonov was a member of the Communist Party of the Soviet Union. His walk in space was originally to have taken place on the Voskhod 1 mission, but this was cancelled, and the historic event happened on the Voskhod 2 flight instead. He was outside the spacecraft for 12 minutes and nine seconds on 18 March 1965, connected to the craft by a tether. At the end of the spacewalk, Leonov's spacesuit had inflated in the vacuum of space to the point where he could not re-enter the airlock. He opened a valve to allow some of the suit's pressure to bleed off and was barely able to get back inside the capsule. Leonov had spent eighteen months undergoing weightlessness training for the mission. In 1968, Leonov was selected to be commander of a circumlunar Soyuz 7K-L1 flight. This was cancelled because of delays in achieving a reliable circumlunar flight (only the later Zond 7 and Zond 8 members of the programme were successful) and the Apollo 8 mission had already achieved that step in the Space Race. He was also selected to be the first Soviet person to land on the Moon, aboard the LOK/N1 spacecraft. This project was also cancelled. (The design required a spacewalk between lunar vehicles, something that contributed to his selection.) Leonov was to have been commander of the 1971 Soyuz 11 mission to Salyut 1, the first crewed space station, but his crew was replaced with the backup after one of the members, cosmonaut Valery Kubasov, was suspected to have contracted tuberculosis (the other member was Pyotr Kolodin). Leonov was to have commanded the next mission to Salyut 1, but this was scrapped after the deaths of the Soyuz 11 crew members, and the space station was lost. The next two Salyuts (actually the military Almaz station) were lost at launch or failed soon after, and Leonov's crew stood by. By the time Salyut 4 reached orbit, Leonov had been switched to a more prestigious project. Leonov's second trip into space was as commander of Soyuz 19, the Soviet half of the 1975 Apollo-Soyuz mission—the first joint space mission between the Soviet Union and the United States. From 1976 to 1982, Leonov was the commander of the cosmonaut team (\"Chief Cosmonaut\") and deputy director of the Yuri Gagarin Cosmonaut Training Center, where he oversaw crew training.

Initially, the slave labour was carried out in a huge stone quarry owned by the \"SS-Deutsche Erd- und Steinwerke GmbH\" (SS German Earth and Stone Works). In the fall of 1940 the use of labour in Upper Silesia was taken over by the new Organization Schmelt formed on the orders of Heinrich Himmler. It was named after its leader \"SS-Oberführer\" Albrecht Schmelt. The company was put in charge of employment from the camps with Jews intended to work for food only. The Gross-Rosen location close to occupied Poland was of considerable advantage. Prisoners were put to work in the construction of a system of subcamps for expelees from the annexed territories. Gross Rosen became an independent camp on 1 May 1941. As the complex grew, the majority of inmates were put to work in the new Nazi enterprises attached to these subcamps. In October 1941 the SS transferred about 3,000 Soviet POWs to Gross-Rosen for execution by shooting. Gross-Rosen was known for its brutal treatment of the so-called \"Nacht und Nebel\" prisoners vanishing without a trace from targeted communities. Most died in the granite quarry. The brutal treatment of the political and Jewish prisoners was not only in the hands of guards and German criminal prisoners brought in by the \"SS\", but to a lesser extent also fuelled by the German administration of the stone quarry responsible for starvation rations and denial of medical help. In 1942, for political prisoners, the average survival time-span was less than two months. Due to a change of policy in August 1942, prisoners were likely to survive longer because they were needed as slave workers in German war industries. Among the companies that benefited from the slave labour of the concentration camp inmates were German electronics manufacturers such as Blaupunkt, Siemens, as well as Krupp, IG Farben, and Daimler-Benz, among others. Some prisoners who were not able to work but not yet dying were sent to the Dachau concentration camp in so-called \"invalid\" transports. The largest population of inmates, however, were Jews, initially from the Dachau and Sachsenhausen camps, and later from Buchenwald.

A total of 125,000 inmates of various nationalities passed through the complex during its existence, of whom an estimated 40,000 died on site, on death marches and in evacuation transports. The camp was liberated on 14 February 1945 by the Red Army. A total of over 500 female camp guards were trained and served in the Gross-Rosen complex. Female SS staffed the women's subcamps of Brünnlitz, Graeben, Gruenberg, Gruschwitz Neusalz, Hundsfeld, Kratzau II, Oberaltstadt, Reichenbach, and Schlesiersee Schanzenbau. The Gabersdorf labour camp had been part of a network of forced labor camps for Jewish prisoners that had operated under Organization Schmelt since 1941. The spinning mill where the female Jewish prisoners worked had been \"Aryanized\" in 1939 by a Vienna-based company called Vereinigte Textilwerke K. H. Barthel & Co.

The cycle was discovered in 1950 by Melvin Calvin, James Bassham, and Andrew Benson at the University of California, Berkeley by using the radioactive isotope carbon-14. Photosynthesis occurs in two stages in a cell. In the first stage, light-dependent reactions capture the energy of light and use it to make the energy-storage and transport molecules ATP and NADPH. The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds that can be used by the organism (and by animals that feed on it). This set of reactions is also called \"carbon fixation\". The key enzyme of the cycle is called RuBisCO. In the following biochemical equations, the chemical species (phosphates and carboxylic acids) exist in equilibria among their various ionized states as governed by the pH. The enzymes in the Calvin cycle are functionally equivalent to most enzymes used in other metabolic pathways such as gluconeogenesis and the pentose phosphate pathway, but they are found in the chloroplast stroma instead of the cell cytosol, separating the reactions. They are activated in the light (which is why the name \"dark reaction\" is misleading), and also by products of the light-dependent reaction. These regulatory functions prevent the Calvin cycle from being respired to carbon dioxide. Energy (in the form of ATP) would be wasted in carrying out these reactions that have no net productivity. The sum of reactions in the Calvin cycle is the following: Hexose (six-carbon) sugars are not a product of the Calvin cycle. Although many texts list a product of photosynthesis as, this is mainly a convenience to counter the equation of respiration, where six-carbon sugars are oxidized in mitochondria. The carbohydrate products of the Calvin cycle are three-carbon sugar phosphate molecules, or \"triose phosphates\", namely, glyceraldehyde-3-phosphate (G3P).", "section_level": 1}, {"title": "Steps.", "content": "In the first stage of the Calvin cycle, a molecule is incorporated into one of two three-carbon molecules (glyceraldehyde 3-phosphate or G3P), where it uses up two molecules of ATP and two molecules of NADPH, which had been produced in the light-dependent stage. The three steps involved are: The next stage in the Calvin cycle is to regenerate RuBP. Five G3P molecules produce three RuBP molecules, using up three molecules of ATP. Since each molecule produces two G3P molecules, three molecules produce six G3P molecules, of which five are used to regenerate RuBP, leaving a net gain of one G3P molecule per three molecules (as would be expected from the number of carbon atoms involved). The regeneration stage can be broken down into steps. Thus, of six G3P produced, five are used to make three RuBP (5C) molecules (totaling 15 carbons), with only one G3P available for subsequent conversion to hexose. This requires nine ATP molecules and six NADPH molecules per three molecules. The equation of the overall Calvin cycle is shown diagrammatically below. RuBisCO also reacts competitively with instead of in photorespiration. The rate of photorespiration is higher at high temperatures. Photorespiration turns RuBP into 3-PGA and 2-phosphoglycolate, a 2-carbon molecule that can be converted via glycolate and glyoxalate to glycine. Via the glycine cleavage system and tetrahydrofolate, two glycines are converted into serine +. Serine can be converted back to 3-phosphoglycerate. Thus, only 3 of 4 carbons from two phosphoglycolates can be converted back to 3-PGA. It can be seen that photorespiration has very negative consequences for the plant, because, rather than fixing, this process leads to loss of.

For the Calvin cycle to continue, RuBP (ribulose 1,5-bisphosphate) must be regenerated. So, 5 out of 6 carbons from the 2 G3P molecules are used for this purpose. Therefore, there is only 1 net carbon produced to play with for each turn. To create 1 surplus G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle. To make one glucose molecule (which can be created from 2 G3P molecules) would require 6 turns of the Calvin cycle.

There is a light-dependent regulation of the cycle enzymes, as the third step requires reduced NADP. There are two regulation systems at work when the cycle must be turned on or off: the thioredoxin/ferredoxin activation system, which activates some of the cycle enzymes; and the RuBisCo enzyme activation, active in the Calvin cycle, which involves its own activase. The thioredoxin/ferredoxin system activates the enzymes glyceraldehyde-3-P dehydrogenase, glyceraldehyde-3-P phosphatase, fructose-1,6-bisphosphatase, sedoheptulose-1,7-bisphosphatase, and ribulose-5-phosphatase kinase, which are key points of the process. This happens when light is available, as the ferredoxin protein is reduced in the photosystem I complex of the thylakoid electron chain when electrons are circulating through it. Ferredoxin then binds to and reduces the thioredoxin protein, which activates the cycle enzymes by severing a cystine bond found in all these enzymes. This is a dynamic process as the same bond is formed again by other proteins that deactivate the enzymes. The implications of this process are that the enzymes remain mostly activated by day and are deactivated in the dark when there is no more reduced ferredoxin available. The enzyme RuBisCo has its own, more complex activation process. It requires that a specific lysine amino acid be carbamylated to activate the enzyme. This lysine binds to RuBP and leads to a non-functional state if left uncarbamylated. A specific activase enzyme, called RuBisCo activase, helps this carbamylation process by removing one proton from the lysine and making the binding of the carbon dioxide molecule possible. Even then the RuBisCo enzyme is not yet functional, as it needs a magnesium ion bound to the lysine to function. This magnesium ion is released from the thylakoid lumen when the inner pH drops due to the active pumping of protons from the electron flow.

He first studied the trombone, then changed to cornet. From 1908 to 1917 he played cornet in New Orleans brass bands and dance bands and in the city's red-light district, which came to be known as Storyville. A band he co-led with trombonist Kid Ory was considered one of the best and hottest in New Orleans in the late 1910s. He was popular in New Orleans across economic and racial lines and was in demand for music jobs of all kinds. According to an interview at Tulane University's Hogan Jazz Archive with Oliver's widow Estella, a fight broke out at a dance where Oliver was playing, and the police arrested him, his band, and the fighters. After Storyville closed, he moved to Chicago in 1918 with his wife and step-daughter, Ruby Tuesday Oliver. In Chicago, he found work with colleagues from New Orleans, such as clarinetist Lawrence Duhé, bassist Bill Johnson, trombonist Roy Palmer, and drummer Paul Barbarin. He became leader of Duhé's band, playing at a number of Chicago clubs. In the summer of 1921 he took a group to the West Coast, playing engagements in San Francisco and Oakland, California. In 1922, Oliver and his band returned to Chicago, where they began performing as King Oliver and his Creole Jazz Band at the Royal Gardens cabaret (later renamed the Lincoln Gardens). In addition to Oliver on cornet, the personnel included his protégé Louis Armstrong on second cornet, Baby Dodds on drums, Johnny Dodds on clarinet, Lil Hardin (later Armstrong's wife) on piano, Honoré Dutrey on trombone, and Bill Johnson on double bass. Recordings made by this group in 1923 for Gennett, Okeh, Paramount, and Columbia demonstrated the New Orleans style of collective improvisation, also known as Dixieland, and brought it to a larger audience. In the mid-1920s Oliver enlarged his band to nine musicians, performing under the name King Oliver and his Dixie Syncopators, and began using more written arrangements with jazz solos. In 1927 the band went to New York, but he disbanded it to do freelance jobs. In the later 1920s, he struggled with playing trumpet due to his gum disease, so he employed others to handle the solos, including his nephew Dave Nelson, Louis Metcalf, and Red Allen. He reunited the band in 1928, recording for Victor Talking Machine Company one year later. He continued with modest success until a downturn in the economy made it more difficult to find bookings. His periodontitis made playing the trumpet difficult. He quit playing music in 1937.", "section_level": 2}, {"title": "Work and influence.", "content": "As a player, Oliver took great interest in altering his horn's sound. He pioneered the use of mutes, including the rubber plumber's plunger, derby hat, bottles and cups. His favorite mute was a small metal mute made by the C.G. Conn Instrument Company, with which he played his famous solo on his composition the \"Dippermouth Blues\" (an early nickname for fellow cornetist Louis Armstrong). His recording \"Wa Wa Wa\" with the Dixie Syncopators can be credited with giving the name wah-wah to such techniques. Oliver was also a talented composer, and wrote many tunes that are still regularly played, including \"Dippermouth Blues,\" \"Sweet Like This,\" \"Canal Street Blues,\" and \"Doctor Jazz.\" Oliver performed mostly on cornet, but like many cornetists he switched to trumpet in the late 1920s. He credited jazz pioneer Buddy Bolden as an early influence, and in turn was a major influence on numerous younger cornet/trumpet players in New Orleans and Chicago, including Tommy Ladnier, Paul Mares, Muggsy Spanier, Johnny Wiggs, Frank Guarente and, the most famous of all, Armstrong. One of his protégés, Louis Panico (cornetist with the Isham Jones Orchestra), authored a book entitled \"The Novelty Cornetist\", which is illustrated with photos showing some of the mute techniques he learned from Oliver. As mentor to Armstrong in New Orleans, Oliver taught young Louis and gave him his job in Kid Ory's band when he went to Chicago. A few years later Oliver summoned him to Chicago to play with his band. Louis remembered Oliver as \"Papa Joe\" and considered him his idol and inspiration. In his autobiography, \"Satchmo: My Life in New Orleans\", Armstrong wrote: \"It was my ambition to play as he did.

The Great Depression brought hardship to Oliver. He lost his life savings to a collapsed bank in Chicago, and he struggled to keep his band together through a series of hand-to-mouth gigs until the group broke up. Oliver also had health problems, such as pyorrhea, a gum disease that was partly caused by his love of sugar sandwiches and it made it very difficult for him to play and he soon began delegating solos to younger players, but by 1935, he could no longer play the trumpet at all. Oliver was stranded in Savannah, Georgia, where he pawned his trumpet and finest suits and briefly ran a fruit stall, then he worked as a janitor at Wimberly's Recreation Hall (526-528 West Broad Street). Oliver died in poverty \"of arteriosclerosis, too broke to afford treatment\" in a Savannah rooming house on April 8 or 10, 1938.

The area was a sovereign state within the Holy Roman Empire for more than 800 years. After the Treaty of Westphalia in 1648 the Jura had close ties with the Swiss Confederation. At the Congress of Vienna (1815), the Jura region became part of the canton of Bern. This act caused dissension. The Jura was French-speaking and Roman Catholic, whereas the canton of Bern was mostly German-speaking and Protestant. After World War II, a separatist movement campaigned for a secession of Jura from the canton of Bern. After a long and partly militant struggle, which included some arson attacks by a youth organisation \"Les Béliers\", a constitution was accepted in 1977. In 1978, the split was made official when the Swiss people voted in favour, and in 1979, the Jura joined the Swiss Confederation as a full member. The canton celebrated its independence from the canton of Bern on 23 June. However, the southern part of the region, which is also predominantly French-speaking but has a Protestant majority, opted not to join the newly formed canton, instead remaining part of the canton of Bern. Although this decision may be considered strange linguistically, the choice may have been influenced by the fact that the canton of Bern is financially richer and is at the heart of federal power in Switzerland. The area is now known as Bernese Jura. The word Jura, therefore, may refer either to canton Jura, or to the combined territory of canton Jura and the Bernese Jura. Switzerland as a whole often presents the latter from a touristic standpoint with documentation easily available in French or German. On creation, the canton adopted the title Republic and canton of the Jura. Other cantons in Switzerland using the title \"Republic and Canton\" are Ticino, the canton of Geneva, and the canton of Neuchâtel. In each case, the title refers to the autonomy of the canton and its nominal sovereignty within the Swiss Confederation. Since 1994, the question of the Jura region has again been controversial. In 2004, a federal commission proposed that the French-speaking southern Jura be united with the canton of Jura, as the language question now seems to be more important than the denominational one. A possible solution would be to create two half-cantons, as reunification with the creation of only a single canton would mean a complete restructuring of the Jura's current political system, with the cantonal capital being transferred from Delémont to Moutier. On 18 June 2017, the town of Moutier voted to quit Bern and join the canton of Jura.

Thirty years later, in 1829, the French naturalist Alexandre Brongniart published a survey on the different terrains that constitute the crust of the Earth.

The Jurassic North Atlantic Ocean was relatively narrow, while the South Atlantic did not open until the following Cretaceous period, when Gondwana itself rifted apart. The Tethys Sea closed, and the Neotethys basin appeared. Climates were warm, with no evidence of a glacier having appeared. As in the Triassic, there was apparently no land over either pole, and no extensive ice caps existed. The Jurassic geological record is good in western Europe, where extensive marine sequences indicate a time when much of that future landmass was submerged under shallow tropical seas; famous locales include the Jurassic Coast World Heritage Site in southern England and the renowned late Jurassic \"lagerstätten\" of Holzmaden and Solnhofen in Germany. In contrast, the North American Jurassic record is the poorest of the Mesozoic, with few outcrops at the surface. Though the epicontinental Sundance Sea left marine deposits in parts of the northern plains of the United States and Canada during the late Jurassic, most exposed sediments from this period are continental, such as the alluvial deposits of the Morrison Formation. The Jurassic was a time of calcite sea geochemistry in which low-magnesium calcite was the primary inorganic marine precipitate of calcium carbonate. Carbonate hardgrounds were thus very common, along with calcitic ooids, calcitic cements, and invertebrate faunas with dominantly calcitic skeletons. The first of several massive batholiths were emplaced in the northern American cordillera beginning in the mid-Jurassic, marking the Nevadan orogeny. Important Jurassic exposures are also found in Russia, India, South America, Japan, Australasia and the United Kingdom. In Africa, Early Jurassic strata are distributed in a similar fashion to Late Triassic beds, with more common outcrops in the south and less common fossil beds which are predominated by tracks to the north. As the Jurassic proceeded, larger and more iconic groups of dinosaurs like sauropods and ornithopods proliferated in Africa.

Esiko's grandson was Otto, Count of Ballenstedt, who died in 1123. By Otto's marriage to Eilika, daughter of Magnus, Duke of Saxony, the Ascanians became heirs to half of the property of the House of Billung, former dukes of Saxony. Otto's son, Albert the Bear, became, with the help of his mother's inheritance, the first Ascanian duke of Saxony in 1139. However, he soon lost control of Saxony to the rival House of Guelph. Albert inherited the Margraviate of Brandenburg in 1157 from its last Wendish ruler, Pribislav, and he became the first Ascanian margrave. Albert, and his descendants of the House of Ascania, then made considerable progress in Christianizing and Germanizing the lands. As a borderland between German and Slavic cultures, the country was known as a march. In 1237 and 1244, two towns, Cölln and Berlin, were founded during the rule of Otto and Johann, grandsons of Margrave Albert the Bear. Later, they were united into one city, Berlin. The emblem of the House of Ascania, a red eagle and bear, became the heraldic emblems of Berlin. In 1320, the Brandenburg Ascanian line came to an end. After the Emperor had deposed the Guelph rulers of Saxony in 1180, Ascanians returned to rule the Duchy of Saxony, which had been reduced to its eastern half by the Emperor. However, even in eastern Saxony, the Ascanians could establish control only in limited areas, mostly near the River Elbe. In the 13th century, the Principality of Anhalt was split off from the Duchy of Saxony. Later, the remaining state was split into Saxe-Lauenburg and Saxe-Wittenberg.

On the other hand, most organic acids are very soluble in organic solvents. \"p\"-Toluenesulfonic acid is a comparatively strong acid used in organic chemistry often because it is able to dissolve in the organic reaction solvent.

These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid (HCl) or mixtures of HCl and hydrofluoric acid (HF). For this reason, organic acids are used at high temperatures or when long contact times between acid and pipe are needed. The conjugate bases of organic acids such as citrate and lactate are often used in biologically-compatible buffer solutions. Citric and oxalic acids are used as rust removal. As acids, they can dissolve the iron oxides, but without damaging the base metal as do stronger mineral acids. In the dissociated form, they may be able to chelate the metal ions, helping to speed removal. Biological systems create many more complex organic acids such as -lactic, citric, and -glucuronic acids that contain hydroxyl or carboxyl groups. Human blood and urine contain these plus organic acid degradation products of amino acids, neurotransmitters, and intestinal bacterial action on food components. Examples of these categories are alpha-ketoisocaproic, vanilmandelic, and -lactic acids, derived from catabolism of -leucine and epinephrine (adrenaline) by human tissues and catabolism of dietary carbohydrate by intestinal bacteria, respectively.", "section_level": 1}, {"title": "Application in food.", "content": "Organic acids are used in food preservation because of their effects on bacteria. The key basic principle on the mode of action of organic acids on bacteria is that non-dissociated (non-ionized) organic acids can penetrate the bacteria cell wall and disrupt the normal physiology of certain types of bacteria that we call \"pH-sensitive\", meaning that they cannot tolerate a wide internal and external pH gradient. Among those bacteria are \"Escherichia coli\", \"Salmonella\" spp., \"C. perfringens\", \"Listeria monocytogenes\", and \"Campylobacter\" species. Upon passive diffusion of organic acids into the bacteria, where the pH is near or above neutrality, the acids will dissociate and lower the bacteria internal pH, leading to situations that will impair or stop the growth of bacteria. On the other hand, the anionic part of the organic acids that cannot escape the bacteria in its dissociated form will accumulate within the bacteria and disrupt many metabolic functions, leading to osmotic pressure increase, incompatible with the survival of the bacteria. It has been well demonstrated that the state of the organic acids (undissociated or dissociated) is extremely important to define their capacity to inhibit the growth of bacteria, compared to undissociated acids.

Organic acids added to feeds should be protected to avoid their dissociation in the crop and in the intestine (high pH segments) and reach far into the gastrointestinal tract, where the bulk of the bacteria population is located. From the use of organic acids in poultry and pigs, one can expect an improvement in performance similar to or better than that of antibiotic growth promoters, without the public health concern, a preventive effect on the intestinal problems like necrotic enteritis in chickens and \"Escherichia coli\" infection in young pigs.

Further discoveries produced several versions of the Mesopotamian flood myth, with the account closest to that in Genesis being found in a 700 BC Babylonian copy of the \"Epic of Gilgamesh\". Many scholars believe that this was probably copied from the Akkadian \"Atra-Hasis\", which dates to the 18th century BC. In the Gilgamesh flood myth, the highest god Enlil decides to destroy the world with a flood because humans have become too noisy. The god Ea, who created humans out of clay and divine blood, secretly warns the hero Utnapishtim of the impending flood and gives him detailed instructions for building a boat so that life may survive. Another Mesopotamian flood myth is the 17th century BC Sumerian creation myth. In the Book of Genesis (c. 6th century BC) the god Yahweh, who created man out of the dust of the ground, decides to flood the earth because of the sinful state of mankind. It is also Yahweh who then gives the protagonist Noah instructions to build an ark in order to preserve human and animal life.

In Zoroastrian Mazdaism, Ahriman tries to destroy the world with a drought, which Mithra ends by shooting an arrow into a rock, from which a flood springs; one man survives in an ark with his cattle. In Plato's \"Timaeus\", written c. 360 BC, Timaeus describes a flood myth similar to the earlier versions. In it, the Bronze race of humans angers the high god Zeus with their constant warring. Zeus decides to punish humanity with a flood. The Titan Prometheus, who had created humans from clay, tells the secret plan to Deucalion, advising him to build an ark in order to be saved.

Excavations in Iraq have revealed evidence of localized flooding at Shuruppak (modern Tell Fara, Iraq) and various other Sumerian cities. A layer of riverine sediments, radiocarbon dated to about 2900 BC, interrupts the continuity of settlement, extending as far north as the city of Kish, which took over hegemony after the flood. Polychrome pottery from the Jemdet Nasr period (3000–2900 BC) was discovered immediately below the Shuruppak flood stratum. Other sites, such as Ur, Kish, Uruk, Lagash, and Ninevah, all present evidence of flooding. However, this evidence comes from different time periods. The Shuruppak flood seems to have been a localised event caused through the damming of the Karun River through the spread of dunes, flooding into the Tigris, and simultaneous heavy rainfall in the Nineveh region, spilling across into the Euphrates. In Israel, there is no such evidence of a widespread flood. Given the similarities in the Mesopotamian flood story and the Biblical account, it would seem that they have a common origin in the memories of the Shuruppak account. The Sumerian King List reads: Floods in the wake of the last glacial period may have inspired myths that survive to this day. It has been postulated that the deluge myth in North America may be based on a sudden rise in sea levels caused by the rapid draining of prehistoric Lake Agassiz at the end of the last Ice Age, about 8,400 years ago. The geography of the Mesopotamian area was considerably changed by the filling of the Persian Gulf after sea waters rose following the last glacial period. Global sea levels were about lower around 18,000 BP and rose until 8,000 BP when they reached current levels, which are now an average above the floor of the Gulf, which was a huge () low-lying and fertile region in Mesopotamia, in which human habitation is thought to have been strong around the Gulf Oasis for 100,000 years. A sudden increase in settlements above the present water level is recorded at around 7,500 BP. Adrienne Mayor promoted the hypothesis that global flood stories were inspired by ancient observations of seashells and fish fossils in inland and mountain areas. The ancient Greeks, Egyptians, and Romans all documented the discovery of such remains in these locations; the Greeks hypothesized that Earth had been covered by water on several occasions, citing the seashells and fish fossils found on mountain tops as evidence of this history. Another hypothesis is that a meteor or comet crashed into the Indian Ocean around 3000–2800 BC, created the undersea Burckle Crater, and generated a giant tsunami that flooded coastal lands. Some of the largest tsunamis in history, resulting from the Chicxulub impact, 66 million years ago, were thought to have affected roughly the entire Americas (or nearly all of the Western Hemisphere). In the late 17th century, there were speculations accounting for the Genesis flood by natural causes. Thomas Burnet’s \"Telluris Theoria Sacra\" (Sacred Theory of the Earth) had water rising from the hollow earth. William Whiston's \"A New Theory of the Earth\" postulated that major changes in the earth’s history could be attributed to the action of comets. Speculation regarding the Deucalion myth has also been introduced, whereby a large tsunami in the Mediterranean Sea, caused by the Thera eruption (with an approximate geological date of 1630–1600 BC), is the myth's historical basis. Although the tsunami hit the South Aegean Sea and Crete, it did not affect cities in the mainland of Greece, such as Mycenae, Athens, and Thebes, which continued to prosper, indicating that it had a local rather than a regionwide effect. Hanns Hörbiger, in his book \"Welteislehre\", which was published in 1912, was of the opinion that the great flood was caused by a moon falling to earth. This moon was afterwards replaced by another moon. A controversial hypothesis of long-term flooding is the Black Sea deluge hypothesis, which argues for a catastrophic deluge about 5600 BC from the Mediterranean Sea into the Black Sea. This has been the subject of considerable discussion. The Younger Dryas impact hypothesis is another proposed natural explanation for flood myths, but this idea is similarly controversial.", "section_level": 1}, {"title": "References.", "content": "Footnotes Citations", "section_level": 1}], "src_summary": "A flood myth or deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution.

The Roman writers Cato (in his \"De Agri Cultura\") and Columella (in his \"De re Rustica\") mentioned preserving cabbages and turnips with salt. Although \"sauerkraut\" is a German word, the dish did not originate in Germany. Some claim that the Mongol Emperor Genghis Khan brought it to Europe. Others claim that it originally came from China and surrounding areas and that the Tatars brought it to Europe, and altered the original Chinese recipe by fermenting it with salt instead of rice wine. It took root mostly in Central and Eastern European cuisines, but also in other countries including the Netherlands, where it is known as \"zuurkool\", and France, where the name became \"choucroute\". The English name is borrowed from German where it means literally \"sour herb\" or \"sour cabbage\". The names in Slavic and other Central and Eastern European languages have similar meanings with the German word: \"fermented cabbage\" (,,,,,,, ) or \"sour cabbage\" (,,,,,,,,,,,,, \"kisla kapusta\"). Before frozen foods, refrigeration, and cheap transport from warmer areas became readily available in northern, central and eastern Europe, sauerkraut – like other preserved foods – provided a source of nutrients during the winter. Captain James Cook always took a store of sauerkraut on his sea voyages, since experience had taught him it prevented scurvy. The word \"Kraut\", derived from this food, is a derogatory term for the German people. During World War I, due to concerns the American public would reject a product with a German name, American sauerkraut makers relabeled their product as \"Liberty Cabbage\" for the duration of the war.", "section_level": 1}, {"title": "Production.", "content": "Sauerkraut is made by a process of pickling called lactic acid fermentation that is analogous to how traditional (not heat-treated) pickled cucumbers and kimchi are made. The cabbage is finely shredded, layered with salt, and left to ferment. Fully cured sauerkraut keeps for several months in an airtight container stored at 15 °C (60 °F) or below. Neither refrigeration nor pasteurization is required, although these treatments prolong storage life. Fermentation by lactobacilli is introduced naturally, as these air-borne bacteria culture on raw cabbage leaves where they grow. Yeasts also are present, and may yield soft sauerkraut of poor flavor when the fermentation temperature is too high. The fermentation process has three phases, collectively sometimes referred to as population dynamics. In the first phase, anaerobic bacteria such as \"Klebsiella\" and \"Enterobacter\" lead the fermentation, and begin producing an acidic environment that favors later bacteria. The second phase starts as the acid levels become too high for many bacteria, and \"Leuconostoc mesenteroides\" and other \"Leuconostoc\" species take dominance. In the third phase, various \"Lactobacillus\" species, including \"L. brevis\" and \"L. plantarum\", ferment any remaining sugars, further lowering the pH. Properly cured sauerkraut is sufficiently acidic to prevent a favorable environment for the growth of \"Clostridium botulinum\", the toxins of which cause botulism. A 2004 genomic study found an unexpectedly large diversity of lactic acid bacteria in sauerkraut, and that previous studies had oversimplified this diversity. \"Weissella\" was found to be a major organism in the initial, heterofermentative stage, up to day 7. It was also found that \"Lactobacillus brevis\" and \"Pediococcus pentosaceus\" had smaller population numbers in the first 14 days than previous studies had reported. The Dutch sauerkraut industry found that inoculating a new batch of sauerkraut with an old batch resulted in an excessively sour product. This sourdough process is known as \"backslopping\" or \"inoculum enrichment\"; when used in making sauerkraut, first- and second-stage population dynamics, important to developing flavor, are bypassed. This is due primarily to the greater initial activity of species \"L. plantarum\".", "section_level": 1}, {"title": "Regional varieties.", "content": "In Azerbaijani, Belarusian, Polish, Russian, Baltic states and Ukrainian cuisine, chopped cabbage is often pickled together with shredded carrots. Other ingredients may include whole or quartered apples for additional flavor or cranberry for flavor and better keeping (the benzoic acid in cranberries is a common preservative). Bell peppers and beets are added in some recipes for colour. The resulting sauerkraut salad is typically served cold, as \"zakuski\" or a side dish. A home made type of very mild sauerkraut is available, where white cabbage is pickled with salt in a refrigerator for only three to seven days. This process results in very little lactic acid production. Sometimes in Russia the double fermentation is used, with the initial step producing an exceptionally sour product, which is then \"corrected\" by adding 30-50% more fresh cabbage and fermenting the mix again. The flavor additives like apples, beets, cranberries and sometimes even watermelons are usually introduced at this step. Sauerkraut may be used as a filling for Polish \"pierogi\", Ukrainian \"varenyky\", Russian \"pirogi\" and \"pirozhki\". Sauerkraut is also the central ingredient in traditional soups, such as \"shchi\" (a national dish of Russia), \"kwaśnica\" (Poland), \"kapustnica\" (Slovakia), and \"zelňačka\" (Czech Republic). It is an ingredient of Polish \"bigos\" (a hunter's stew). In Germany, cooked sauerkraut is often flavored with juniper berries or caraway seeds; apples and white wine are added in popular variations. Traditionally it is served warm, with pork (e.g. \"eisbein\", \"schweinshaxe\", \"Kassler\") or sausages (smoked or fried sausages, \"Frankfurter Würstchen\", Vienna sausages, black pudding), accompanied typically by roasted or steamed potatoes or dumplings (\"knödel\" or \"schupfnudel\"). Similar recipes are common in other Central European cuisines. The Czech national dish \"vepřo knedlo zelo\" consists of roast pork with \"knedliky\" and sauerkraut. In France, sauerkraut is the main ingredient of the Alsatian meal \"choucroute garnie\" (French for \"dressed sauerkraut\"), sauerkraut with sausages (Strasbourg sausages, smoked Morteau or Montbéliard sausages), charcuterie (bacon, ham, etc.), and often potatoes. Sauerkraut, along with pork, is eaten traditionally in Pennsylvania on New Year's Day. The tradition, started by the Pennsylvania Dutch, is thought to bring good luck for the upcoming year.

In 1704 he travelled to Copenhagen to enter the University of Copenhagen, where he earned a Bachelor's degree in Theology. He returned to Hinnøya Island after graduation, and in April 1707 he was ordained and assigned to a parish on the equally remote archipelago of Lofoten. Also in 1707 he married Gertrud Rasch (or \"Rask\"), who was 13 years his senior. Four children were born to the marriage – two boys and two girls.", "section_level": 1}, {"title": "Greenland.", "content": "At Lofoten, Egede heard stories about the old Norse settlements on Greenland, with which contact had been lost centuries before. Beginning in 1711, he sought permission from Frederick IV of Denmark to search for the colony and establish a mission there, presuming that it had either remained Catholic after the Danish Reformation or been lost to the Christian faith altogether. Frederick gave consent at least partially to re-establish a colonial claim to the island. Egede established the Bergen Greenland Company (\"\") with $9,000 in capital from Bergen merchants, $200 from the Danish king, and a $300 annual grant from the Royal Mission College. The company was granted broad powers to govern the peninsula (as it was then considered to be), to raise its own army and navy, to collect taxes and to administer justice; the king and his council, however, refused to grant it monopoly rights to whaling and trade in Greenland out of a fear of antagonizing the Dutch. \"Haabet\" (\"The Hope\") and two smaller ships departed Bergen on 2 May 1721 bearing Egede, his wife and four children, and forty other colonists. On 3 July they reached Nuup Kangerlua and established Hope Colony (\"\") with the erection of a portable house on Kangeq Island, which Egede christened the Island of Hope (\"Haabet Oe\"). Searching for months for descendants of the old Norse colonists, he found only the local Inuit people and began studying their language. Missionising among them required some imagination as, for instance, the Inuit had no bread nor any idea of it, requiring the Lord's Prayer to be translated as \"Give us this day our daily seal\". By the end of the first winter, many of the colonists had been stricken with scurvy and most returned home as soon as they could. Egede and his family remained with a few others and in 1722 welcomed two supply ships the king had funded with the imposition of a new tax. His (now ship-borne) explorations found no Norse survivors along the western shore and future work was misled by the two mistaken beliefs both prevalent at the time that the Eastern Settlement would be located on Greenland's east coast (it was later established it had been among the fjords of the island's extreme southwest) and that a strait existed nearby communicating with the western half of the island. In fact, his 1723 expedition found the churches and ruins of the Eastern Settlement, but he considered them to be those of the Western. At the end of the year, he turned north and helped establish a whaling station on Nipisat Island. In 1724 he baptized his first child converts, two of whom would travel to Denmark and there inspire Count Zinzendorf to begin the Moravian missions. In 1728, a royal expedition under Major Claus Paarss arrived with four supply ships and moved the Kangeq colony to the mainland opposite, establishing a fort named Godt-Haab (\"Good Hope\"), the future Godthåb. The extra supplies also allowed Egede to build a proper chapel within the main house. More scurvy led to forty deaths and abandonment of the site not only by the Danes but by the Inuit as well. Egede's book \"The Old Greenland's New Perlustration\" () appeared in 1729 and was translated into several languages, but King Frederick had lost patience and recalled Paarss's military garrison from Greenland the next year. Egede, encouraged by his wife Gertrud, remained with his family and ten sailors. A supply ship in 1733 brought three missionaries and news that the king had granted 2,000 rixdollars a year to establish a new company for the colony under Jacob Severin. The Moravians were allowed to establish a station at Neu-Herrnhut (which became the nucleus of modern Nuuk, Greenland's capital) and in time a string of missions along the island's west coast. The ship also returned one of Egede's convert children with a case of smallpox. By the next year, the epidemic was raging among the Inuit and in 1735 it claimed Gertrud Egede. Hans carried her body back to Denmark for burial the next year, leaving his son Poul to carry on his work. In Copenhagen, he was named Superintendent of the Greenland Mission Seminary (\"Seminarium Groenlandicum\") and in 1741 the Lutheran Bishop of Greenland.

There are several surviving statues of him as a scribe, portraying him as a young man and as an older man. He was a deified human and thus was depicted only in human form. His cult was initially limited to the Thebes area, with a funerary temple constructed to him during his lifetime next to that of Amenhotep III. This was clearly an exceptional privilege, as it was the only private cult temple to be built among the royal monuments in the area. He continued to be worshipped for at least three centuries after his death, and evidence of this worship persists in a 26th Dynasty votary inscription on a statue dedicated to Amenhotep by a daughter of the pharaoh. During the period of the Ptolemaic Kingdom, his worship saw a resurgence which led to chapels being dedicated to him in the Temple of Hathor at Deir el-Medina and the Mortuary Temple of Hatshepsut at Deir el-Bahari. Statues were erected to him in the Temple of Amun at Karnak and he was treated as an intermediary with the god Amun. Amenhotep also utilised his influence with the king to secure royal patronage for the town of Athribis, for the local god, and the temple dedicated to that god. Manetho gives a legendary account of how Amenhotep advised a king named Amenophis, who was \"desirous to become a spectator of the gods, as had Orus, one of his predecessors in that kingdom, desired the same before him\".

For many businessmen in Sicily, they provide an essential service when they cannot rely on the police and judiciary to enforce their contracts and protect their properties from thieves (this is often because they are engaged in black market deals). Scholars have observed that many other societies around the world have criminal organizations of their own that provide essentially the same protection service through similar methods. For instance, in Russia after the collapse of Communism, the state security system had all but collapsed, forcing businessmen to hire criminal gangs to enforce their contracts and protect their properties from thieves. These gangs are popularly called \"the Russian Mafia\" by foreigners, but they prefer to go by the term \"krysha\". In his analysis of the Sicilian Mafia, Gambetta provided the following hypothetical scenario to illustrate the Mafia's function in the Sicilian economy. Suppose a grocer wants to buy meat from a butcher without paying sales tax to the government. Because this is a black market deal, neither party can take the other to court if the other cheats. The grocer is afraid that the butcher will sell him rotten meat. The butcher is afraid that the grocer will not pay him. If the butcher and the grocer can't get over their mistrust and refuse to trade, they would both miss out on an opportunity for profit. Their solution is to ask the local mafioso to oversee the transaction, in exchange for a fee proportional to the value of the transaction but below the legal tax.

Formulated by Milton Friedman, it argues that excessive expansion of the money supply is inherently inflationary, and that monetary authorities should focus solely on maintaining price stability. This theory draws its roots from two historically antagonistic schools of thought: the hard money policies that dominated monetary thinking in the late 19th century, and the monetary theories of John Maynard Keynes, who, working in the inter-war period during the failure of the restored gold standard, proposed a demand-driven model for money. While Keynes had focused on the stability of a currency's value, with panics based on an insufficient money supply leading to the use of an alternate currency and collapse of the monetary system, Friedman focused on price stability. The result was summarised in a historical analysis of monetary policy, \"Monetary History of the United States 1867–1960\", which Friedman coauthored with Anna Schwartz. The book attributed inflation to excess money supply generated by a central bank. It attributed deflationary spirals to the reverse effect of a failure of a central bank to support the money supply during a liquidity crunch. Friedman originally proposed a fixed \"monetary rule\", called Friedman's k-percent rule, where the money supply would be automatically increased by a fixed percentage per year. Under this rule, there would be no leeway for the central reserve bank, as money supply increases could be determined \"by a computer\", and business could anticipate all money supply changes. With other monetarists he believed that the active manipulation of the money supply or its growth rate is more likely to destabilise than stabilise the economy.", "section_level": 1}, {"title": "Opposition to the gold standard.", "content": "Most monetarists oppose the gold standard. Friedman, for example, viewed a pure gold standard as impractical. For example, whereas one of the benefits of the gold standard is that the intrinsic limitations to the growth of the money supply by the use of gold would prevent inflation, if the growth of population or increase in trade outpaces the money supply, there would be no way to counteract deflation and reduced liquidity (and any attendant recession) except for the mining of more gold.", "section_level": 2}, {"title": "Rise.", "content": "Clark Warburton is credited with making the first solid empirical case for the monetarist interpretation of business fluctuations in a series of papers from 1945. Within mainstream economics, the rise of monetarism accelerated from Milton Friedman's 1956 restatement of the quantity theory of money. Friedman argued that the demand for money could be described as depending on a small number of economic variables. Thus, where the money supply expanded, people would not simply wish to hold the extra money in idle money balances; i.e., if they were in equilibrium before the increase, they were already holding money balances to suit their requirements, and thus after the increase they would have money balances surplus to their requirements. These excess money balances would therefore be spent and hence aggregate demand would rise. Similarly, if the money supply were reduced people would want to replenish their holdings of money by reducing their spending. In this, Friedman challenged a simplification attributed to Keynes suggesting that \"money does not matter.\" Thus the word'monetarist' was coined. The rise of the popularity of monetarism also picked up in political circles when Keynesian economics seemed unable to explain or cure the seemingly contradictory problems of rising unemployment and inflation in response to the collapse of the Bretton Woods system in 1972 and the oil shocks of 1973. On the one hand, higher unemployment seemed to call for Keynesian reflation, but on the other hand rising inflation seemed to call for Keynesian disinflation. In 1979, United States President Jimmy Carter appointed as Federal Reserve chief Paul Volcker, who made fighting inflation his primary objective, and who restricted the money supply (in accordance with the Friedman rule) to tame inflation in the economy. The result was a major rise in interest rates, not only in the United States; but worldwide. The \"Volcker shock\" continued from 1979 to the summer of 1982, decreasing inflation and increasing unemployment. By the time Margaret Thatcher, Leader of the Conservative Party in the United Kingdom, won the 1979 general election defeating the sitting Labour Government led by James Callaghan, the UK had endured several years of severe inflation, which was rarely below the 10% mark and by the time of the May 1979 general election, stood at 15.4%. Thatcher implemented monetarism as the weapon in her battle against inflation, and succeeded at reducing it to 4.6% by 1983. However, unemployment in the United Kingdom increased from 5.7% in 1979 to 12.2% in 1983, reaching 13.0% in 1982; starting with the first quarter of 1980, the UK economy contracted in terms of real gross domestic product for six straight quarters. Monetarists not only sought to explain present problems; they also interpreted historical ones. Milton Friedman and Anna Schwartz in their book \"A Monetary History of the United States, 1867–1960\" argued that the Great Depression of the 1930s was caused by a massive contraction of the money supply (they deemed it \"the Great Contraction\"), and not by the lack of investment Keynes had argued. They also maintained that post-war inflation was caused by an over-expansion of the money supply. They made famous the assertion of monetarism that \"inflation is always and everywhere a monetary phenomenon.\" Many Keynesian economists initially believed that the Keynesian vs. monetarist debate was solely about whether fiscal or monetary policy was the more effective tool of demand management. By the mid-1970s, however, the debate had moved on to other issues as monetarists began presenting a fundamental challenge to Keynesianism. Monetarists argued that central banks sometimes caused major unexpected fluctuations in the money supply. They asserted that actively increasing demand through the central bank can have negative unintended consequences.", "section_level": 1}, {"title": "Current state.", "content": "Former Federal Reserve chairman Alan Greenspan argued that the 1990s decoupling was explained by a virtuous cycle of productivity and investment on one hand, and a certain degree of \"irrational exuberance\" in the investment sector on the other.

The central test case over the validity of these theories would be the possibility of a liquidity trap, like that experienced by Japan. Ben Bernanke, Princeton professor and another former chairman of the U.S. Federal Reserve, argued that monetary policy could respond to zero interest rate conditions by direct expansion of the money supply.

In 605 BC he and his ally Cyaxares, ruler of the Medes, led an army against the Assyrians and Egyptians, who were then occupying Syria, and in the ensuing Battle of Carchemish, Pharaoh Necho II was defeated and Syria and Phoenicia were brought under the control of Babylon. Nabopolassar died in August 605 BC, and Nebuchadnezzar returned to Babylon to ascend the throne. For the next few years, his attention was devoted to subduing his eastern and northern borders, and in 595/4 BC there was a serious but brief rebellion in Babylon itself. In 594/3 BC, the army was sent again to the west, possibly in reaction to the elevation of Psamtik II to the throne of Egypt. During the Siege of Jerusalem, Nebuchadnezar captured King Jehoiachin along with prominent citizens and craftsman and appointed Zedekiah as King of Judah in his place, the latter rebelled and attempted to organize opposition among the small states in the region but his capital, Jerusalem, was taken in 587 BC (the events are described in the Bible's Books of Kings and Book of Jeremiah). In the following years, Nebuchadnezzar incorporated Phoenicia and the former Assyrian provinces of Cilicia (southwestern Anatolia) into his empire and may have campaigned in Egypt. According to a Babylonian poem, Nebuchadnezzar began behaving irrationally in his final years, \"pay[ing] no heed to son or daughter,\" and was deeply suspicious of his sons. The kings who came after him ruled only briefly and Nabonidus, apparently not of the royal family, was overthrown by the Persian conqueror Cyrus the Great less than twenty-five years after Nebuchadnezzar's death. The ruins of Nebuchadnezzar's Babylon are spread over two thousand acres, forming the largest archaeological site in the Middle East.

Daniel 1 introduces Nebuchadnezzar as the king who takes Daniel and other Hebrew youths into captivity in Babylon, to be trained in \"the learning and the tongue of the Chaldeans\".

The consensus among critical scholars is that the book of Daniel is historical fiction. Nebuchadnezzar's recognition of the power of Yahweh is unlikely to have actually occurred.

Fiscal policy in the German Empire was predominantly the domain of the various states responsible for all direct taxation according to the 1833 \"Zollverein\" treaties. The federal government merely received indirect contributions from the states. Matters of fiscal policy at the federal level initially was the exclusive responsibility of the German Chancellery under Otto von Bismarck. However, in 1877 a special finance department was established, which with effect from 14 July 1879 was separated from the chancellery as the Imperial Treasury (\"Reichsschatzamt\"), a federal agency in its own right. With its seat vis-à-vis on Wilhelmplatz in Berlin, it was first headed by a subsecretary, and from 1880 by a Secretary of State only answerable to the chancellor. After World War I, the newly established Weimar Republic had to face huge reparations and a fiscal emergency. To cope with the implications, the former \"Reichsschatzamt\" in 1919 was re-organised as a federal ministry, the \"Reichsministerium der Finanzen\", as supreme financial authority headed by a federal minister. Besides a Reich Treasury Ministry (\"Reichsschatzministerium\") was established for the administration of the federal property, both agencies were merged in 1923. Already in the German cabinet of Chancellor Franz von Papen, Undersecretary Lutz Graf Schwerin von Krosigk was appointed Finance Minister in 1932, an office he held throughout the Nazi era until 1945.

In the first step of alcoholic fermentation, the enzyme invertase cleaves the glycosidic linkage between the glucose and fructose molecules. Next, each glucose molecule is broken down into two pyruvate molecules in a process known as glycolysis. Glycolysis is summarized by the equation: CHCOCOO is pyruvate, and P is inorganic phosphate. Finally, pyruvate is converted to ethanol and CO in two steps, regenerating oxidized NAD+ needed for glycolysis: catalyzed by pyruvate decarboxylase This reaction is catalyzed by alcohol dehydrogenase (ADH1 in baker's yeast).

However, many yeasts such as the commonly used baker's yeast \"Saccharomyces cerevisiae\" or fission yeast \"Schizosaccharomyces pombe\" under certain conditions, ferment rather than respire even in the presence of oxygen. In wine making this is known as the counter-Pasteur effect. These yeasts will produce ethanol even under aerobic conditions, if they are provided with the right kind of nutrition. During batch fermentation, the rate of ethanol production per milligram of cell protein is maximal for a brief period early in this process and declines progressively as ethanol accumulates in the surrounding broth. Studies demonstrate that the removal of this accumulated ethanol does not immediately restore fermentative activity, and they provide evidence that the decline in metabolic rate is due to physiological changes (including possible ethanol damage) rather than to the presence of ethanol. Several potential causes for the decline in fermentative activity have been investigated. Viability remained at or above 90%, internal pH remained near neutrality, and the specific activities of the glycolytic and alcohologenic enzymes (measured in vitro) remained high throughout batch fermentation.

His portraits and self-portraits recall an attention to detail and insight often lost in his grander paintings. His closeness to Johann Joachim Winckelmann has enhanced his historical importance.

Due to its simplicity, bubble sort is often used to introduce the concept of an algorithm, or a sorting algorithm, to introductory computer science students. However, some researchers such as Owen Astrachan have gone to great lengths to disparage bubble sort and its continued popularity in computer science education, recommending that it no longer even be taught. The Jargon File, which famously calls bogosort \"the archetypical [sic] perversely awful algorithm\", also calls bubble sort \"the generic bad algorithm\". Donald Knuth, in \"The Art of Computer Programming\", concluded that \"the bubble sort seems to have nothing to recommend it, except a catchy name and the fact that it leads to some interesting theoretical problems\", some of which he then discusses. Bubble sort is asymptotically equivalent in running time to insertion sort in the worst case, but the two algorithms differ greatly in the number of swaps necessary. Experimental results such as those of Astrachan have also shown that insertion sort performs considerably better even on random lists. For these reasons many modern algorithm textbooks avoid using the bubble sort algorithm in favor of insertion sort. Bubble sort also interacts poorly with modern CPU hardware. It produces at least twice as many writes as insertion sort, twice as many cache misses, and asymptotically more branch mispredictions. Experiments by Astrachan sorting strings in Java show bubble sort to be roughly one-fifth as fast as an insertion sort and 70% as fast as a selection sort. In computer graphics bubble sort is popular for its capability to detect a very small error (like swap of just two elements) in almost-sorted arrays and fix it with just linear complexity (2\"n\").

In French opera of the late eighteenth century (such as the works of Gluck, Grétry and Méhul), \"reminiscence motif\" can be identified, which may recur at a significant juncture in the plot to establish an association with earlier events. Their use, however, is not extensive or systematic. The power of the technique was exploited early in the nineteenth century by composers of Romantic opera, such as Carl Maria von Weber, where recurring themes or ideas were sometimes used in association with specific characters (e.g. Samiel in \"Der Freischütz\" is coupled with the chord of a diminished seventh). The first use of the word \"leitmotif\" in print was by the critic Friedrich Wilhelm Jähns in describing Weber's work, although this was not until 1871. Motifs also figured occasionally in purely instrumental music of the Romantic period. The related idea of the musical \"idée fixe\" was coined by Hector Berlioz in reference to his \"Symphonie fantastique\" (1830). This purely instrumental, programmatic work (subtitled \"Episode in the Life of an Artist\") features a recurring melody representing the object of the artist's obsessive affection and depicting her presence in various real and imagined situations. Though perhaps not corresponding to the strict definition of leitmotif, several of Verdi's operas feature similar thematic tunes, often introduced in the overtures or preludes, and recurring to mark the presence of a character or to invoke a particular sentiment. In \"La forza del destino\", the opening theme of the overture recurs whenever Leonora feels guilt or fear. In \"Il trovatore\", the theme of the first aria by Azucena is repeated whenever she invokes the horror of how her mother was burnt alive and the devastating revenge she attempted then. In \"Don Carlos\", there are at least three leitmotifs that recur regularly across the five acts: the first is associated with the poverty and suffering from war, the second is associated with prayers around the tomb of Carlos V, and the third is introduced as a duet between Don Carlo and the Marquis of Posa, thereafter accentuating sentiments of sincere friendship and loyalty.", "section_level": 2}, {"title": "Wagner.", "content": "Richard Wagner is the earliest composer most specifically associated with the concept of leitmotif. His cycle of four operas, \"Der Ring des Nibelungen\" (the music for which was written between 1853 and 1869), uses hundreds of leitmotifs, often related to specific characters, things, or situations. While some of these leitmotifs occur in only one of the operas, many recur throughout the entire cycle. Wagner had raised the issue of how music could best unite disparate elements of the plot of a music drama in his essay \"Opera and Drama\" (1851); the leitmotif technique corresponds to this ideal. Some controversy surrounded the use of the word in Wagner's own circle: Wagner never authorised the use of the word \"leitmotiv\", using words such as \"Grundthema\" (basic idea), or simply \"Motiv\". His preferred name for the technique was \"Hauptmotiv\" (principal motif), which he first used in 1877; the only time he used the word \"Leitmotiv\", he referred to \"so-called Leitmotivs\". The word gained currency with the overly literal interpretations of Wagner's music by Hans von Wolzogen, who in 1876 published a \"Leitfaden\" (guide or manual) to the \"Ring\". In it he claimed to have isolated and named all of the recurring motifs in the cycle (the motif of \"Servitude\", the \"Spear\" or \"Treaty\" motif, etc.), often leading to absurdities or contradictions with Wagner's actual practice. Some of the motifs he identified began to appear in the published musical scores of the operas, arousing Wagner's annoyance; his wife Cosima Wagner quoted him as saying \"People will think all this nonsense is done at my request!\". In fact Wagner himself never publicly named any of his leitmotifs, preferring to emphasize their flexibility of association, role in the musical form, and emotional effect. The practice of naming leitmotifs nevertheless continued, featuring in the work of prominent Wagnerian critics Ernest Newman, Deryck Cooke and Robert Donington. The resulting lists of leitmotifs also attracted the ridicule of anti-Wagnerian critics and composers (such as Eduard Hanslick, Claude Debussy, and Igor Stravinsky). They identified the motif with Wagner's own approach to composing, mocking the impression of a musical \"address book\" or list of \"cloakroom numbers\" it created.", "section_level": 2}, {"title": "After Wagner.", "content": "Since Wagner, the use of leitmotifs has been taken up by many other composers. Richard Strauss used the device in many of his operas and several of his symphonic poems.

Arnold Schoenberg used a complex set of leitmotifs in his choral work \"Gurre-Lieder\" (completed 1911). Alban Berg's opera \"Wozzeck\" (1914–1922) also utilizes leitmotifs.

He notes that \"even in Wagner's own day the public made a crude link between the leitmotifs and the persons they characterised\" because people's innate mental processes did not necessarily correspond with Wagner's subtle intentions or optimistic expectations.

The headquarter buildings were vacated in 1993, renamed Clock Tower Place, and subsequently redeveloped as Mill & Main Place, a 1.1 million square foot facility for offices and light industry. Initially focusing on the small end of the computer market allowed DEC to grow without its potential competitors making serious efforts to compete with them. Their PDP series of machines became popular in the 1960s, especially the PDP-8, widely considered to be the first successful minicomputer. Looking to simplify and update their line, DEC replaced most of their smaller machines with the PDP-11 in 1970, eventually selling over 600,000 units and cementing DEC's position in the industry. Originally designed as a follow-on to the PDP-11, DEC's VAX-11 series was the first widely used 32-bit minicomputer, sometimes referred to as \"superminis\". These systems were able to compete in many roles with larger mainframe computers, such as the IBM System/370. The VAX was a best-seller, with over 400,000 sold, and its sales through the 1980s propelled the company into the second largest computer company in the industry. At its peak, DEC was the second largest employer in Massachusetts, second only to the Massachusetts State Government. The rapid rise of the business microcomputer in the late 1980s, and especially the introduction of powerful 32-bit systems in the 1990s, quickly eroded the value of DEC's systems. DEC's last major attempt to find a space in the rapidly changing market was the DEC Alpha 64-bit RISC instruction set architecture. DEC initially started work on Alpha as a way to re-implement their VAX series, but also employed it in a range of high-performance workstations. Although the Alpha processor family met both of these goals, and, for most of its lifetime, was the fastest processor family on the market, extremely high asking prices were outsold by lower priced x86 chips from Intel and clones such as AMD.

The Bull prescribed that four (out of seven) votes would always suffice to elect a new King; as a result, three Electors could no longer block the election.

The decision to hold the elections in Frankfurt reflected a traditional feeling dating from East Frankish days that both election and coronation ought to take place on Frankish soil. However, the election location was not the only specified location; the bull specified that the coronation would take place in Aachen, and Nuremberg would be the place where the first diet of a reign should be held. The elections were to be concluded within thirty days; failing that, the bull prescribed that the prince-electors were to receive only bread and water until they had decided: Besides regulating the election process, the chapters of the Golden Bull contained many minor decrees.

In competitive vaulting, the rider and horse will both be judged on a scale from 1 to 10. Vaulting competitions consist of compulsory exercises and choreographed freestyle exercises done to music. There are seven compulsory exercises: mount, basic seat, flag, mill, scissors, stand and flank. Each exercise is scored on a scale from 0 to 10. Horses also receive a score and are judged on the quality of their movement as well as their behavior. Vaulters compete in team, pas-de-deux and individual categories.

She was of distinguished noble heritage: the Vita Mahthildis identifies her as \"augusti de palatio\" and the Annales Magdeburgenses describe her as \"Grecam illustrem imperatoriae stirpi proximam, ingenio facundam\". Recent research tends to concur that she was most probably the daughter of Tzimiskes' brother-in-law (from his first marriage) Constantine Skleros (c. 920–989) and cousin Sophia Phokas, the daughter of \"Kouropalatēs\" Leo Phokas, brother of Emperor Nikephoros II (c. 912–969).", "section_level": 1}, {"title": "Marriage.", "content": "Theophanu was not \"born in the purple\" as the Ottonians would have preferred. The Saxon chronicler Bishop Thietmar of Merseburg writes that the Ottonian preference was for Anna Porphyrogenita, a daughter of late Emperor Romanos II. Theophanu's uncle John I Tzimiskes had overthrown his predecessor Nikephoros II Phokas in 969. Theophanu was escorted back to Rome for her wedding by a delegation of German and Italian churchmen and nobles. When the Ottonian court discovered Theophanu was not a scion of the Macedonian dynasty, as had been assumed, Otto I was told by some to send Theophanu away. His advisors believed that Theophanu's relation to the usurper John Tzimiskes would invalidate the marriage as a confirmation of Otto I as Holy Roman Emperor.. He was persuaded to allow her to stay when it was pointed out that John Tzimiskes had wed Theodora, a member of the Macedonian dynasty and sister to Emperor Romanos II. John was therefore was a Macedonian, by marriage if not by birth. Otto I must have been convinced, because Theophanu and Otto's heir, Otto II, were married on 14 April 972. Otto I was told by some to send Theophanu away, on account of the notion that her questionable imperial origin would not legitimize the emperorship. A reference by the Pope to Emperor Nikephoros II as \"Emperor of the Greeks\" in a letter while Otto's ambassador, Bishop Liutprand of Cremona, was at the Byzantine court, had destroyed the first round of marriage negotiations. With the ascension of John I Tzimiskes, who had not been personally referred to other than as Roman Emperor, the treaty negotiations were able to resume. However, not until a third delegation led by Archbishop Gero of Cologne arrived in Constantinople, were they successfully completed. After the marriage negotiations completed, Theophanu and Otto II were married by Pope John XIII in April 972 and she was crowned as Holy Roman Empress the same day in Rome. According to Karl Leysers' book \"Communications and Power in Medieval Europe: Carolingian and Ottonian,\" Otto I's choice was not \"to be searched for in the parlance of high politics\" as his decision was ultimately made on the basis of securing his dynasty with the birth of the next Ottonian emperor.", "section_level": 1}, {"title": "Empress.", "content": "Otto II succeeded his father on 8 May 973. Theophanu accompanied her husband on all his journeys, and she is mentioned in approximately one quarter of the emperor's formal documents - evidence of her privileged position, influence and interest in affairs of the empire. It is known that she was frequently at odds with her mother-in-law, Adelaide of Italy, which caused an estrangement between Otto II and Adelaide. According to Abbot Odilo of Cluny, Adelaide was very happy when \"that Greek woman\" died. The Benedictine chronicler Alpert of Metz describes Theophanu as being an unpleasant and chattery woman. Theophanu was also criticized for having introduced new luxurious garments and jewelry into France and Germany. The theologian Peter Damian even asserts that Theophanu had a love affair with John Philagathos, a Greek monk who briefly reigned as Antipope John XVI. Otto II died suddenly on 7 December 983 at the age of 28, probably from malaria. His three-year-old son, Otto III, had already been appointed King of the Romans during a diet held on Pentecost of that year at Verona. At Christmas, Theophanu had him crowned by the Mainz archbishop Willigis at Aachen Cathedral, with herself ruling as Empress Regent on his behalf. Upon the death of Emperor Otto II, Bishop Folcmar of Utrecht released his cousin, the Bavarian duke Henry the Quarrelsome from custody. Duke Henry allied with Archbishop Warin of Cologne and seized his nephew Otto III in spring 984, while Theophanu was still in Italy.

In fact, many queens in the tenth century, on an account of male rulers dying early deaths, found themselves in power, creating an age of women rulers for a small period of time. During her regency, Theophanu brought from her native east, a culture of royal women at the helm of a small amount of political power, something that the West--of which she was in rule of--had remained generally opposed to for centuries before her regency. Theophanu and her mother-in-law, Adelaide, are known during the empress' regency to have butted heads frequently--Adelaide of Italy is even quoted as referring to her as \"that Greek empress.\" Theophanu's rivalry with her mother-in-law, according to historian and author Simon Maclean, is overstated. Theophanu's \"Greekness\" was not an overall issue, moreover, there was a grand fascination with the culture surrounding Byzantine court in the west that slighted most criticisms to her Greek origin. Theophanu did not remain merely as an image of the Ottonian empire, but as an influence within the Holy Roman Empire. She intervened within the governing of the empire a total of seventy-six times during the reign of her husband Otto II—perhaps a foreshadowing of her regency. Her first act as regent was in securing her son, Otto III, as the heir to the Holy Roman Empire. Theophanu also placed her daughters in power by giving them high positions in influential nunneries all around the Ottonian-ruled west, securing power for all her children. She welcomed ambassadors, declaring herself \"imperator\" or \"imperatrix\", as did her relative contemporaries Irene of Athens and Theodora; the starting date for her reign being 972, the year of her marriage to the late Otto II. Though never donning any armor, she also waged war and sought peace agreements throughout her regency. Theophanu's regency is a time of considerable peace, as the years 985-991 passed without major crises. Though the myth of Theophanu's prowess as \"imperator\" could be an overstatement, according to historian Gerd Althoff, royal charters present evidence that magnates were at the core of governing the empire. Althoff remarks this as unusual, seeing that kings or emperors in the middle ages rarely shared such a large beacon of empirical power with nobility. Due to illness beginning in 988, Theophanu eventually died at Nijmegen and was buried in the Church of St. Pantaleon near her wittum in Cologne in 991. The chronicler Thietmar eulogized her as follows: \"\"Though [Theophanu] was of the weak sex she possessed moderation, trustworthiness, and good manners. In this way she protected with male vigilance the royal power for her son, friendly with all those who were honest, but with terrifying superiority against rebels\".\" Because Otto III was still a child, his grandmother Adelaide of Italy took over the regency until Otto III became old enough to rule on his own.", "section_level": 1}], "src_summary": "Theophanu (; also \"Theophania\", \"Theophana\", or \"Theophano\"; Medieval Greek ; AD 955 15 June 991) was empress of the Holy Roman Empire by marriage to Emperor Otto II, and regent of Empire during the minority of their son, Emperor Otto III, from 983 until her death in 991.

It was the terminus for the railways of southwestern France until 1939. By 1939 the station's short platforms had become unsuitable for the longer trains that had come to be used for mainline services. After 1939 it was used for suburban services and part of it became a mailing centre during World War II. It was then used as a set for several films, such as Kafka's \"The Trial\" adapted by Orson Welles, and as a haven for the Renaud–Barrault Theatre Company and for auctioneers, while the Hôtel Drouot was being rebuilt. In 1970, permission was granted to demolish the station but Jacques Duhamel, Minister for Cultural Affairs, ruled against plans to build a new hotel in its stead. The station was put on the supplementary list of Historic Monuments and finally listed in 1978. The suggestion to turn the station into a museum came from the Directorate of the Museum of France. The idea was to build a museum that would bridge the gap between the Louvre and the National Museum of Modern Art at the Georges Pompidou Centre. The plan was accepted by Georges Pompidou and a study was commissioned in 1974. In 1978, a competition was organized to design the new museum.

Around 2–4 eggs are laid, and mostly incubated by the female.

First, multiple lines of evidence in the 1970s and 1980s suggested that the New World vultures Cathartidae were more closely related to storks and herons (Ciconiiformes), though more recent work places them outside that group as well. Consequently, New World vultures are now often raised to the rank of an independent order Cathartiformes not closely associated with either birds of prey or storks or herons. In 2007, the American Ornithologists' Union's North American checklist moved Cathartidae back into the lead position in Falconiformes, but with an asterisk that indicates it is a taxon \"that is probably misplaced in the current phylogenetic listing but for which data indicating proper placement are not yet available\". In Europe, it has become common to split the remaining raptors into two: the falcons and caracaras remain in the order Falconiformes (about 60 species in 4 groups), and the remaining 220-odd species (including the Accipitridae eagles, hawks, Old World vultures, etc.) are put in the separate order Accipitriformes. An unplaced prehistoric family known only from fossils are the Horusornithidae. In agreement with the split of Falconiformes and Accipitriformes, comparative genome analysis published in 2008 suggested that falcons are more closely related to the parrots and passerines than to other birds including the Accipitridae, so that the traditional Falconiformes are polyphyletic even if the Cathartidae are excluded. Indeed, a 2011 analysis of transposable element insertions shared between the genomes of falcons, passerines, and parrots, but not present in the genomes of other birds, confirmed that falcons are a sister group of the combined parrot/passerine group, together forming the clade Eufalconimorphae.", "section_level": 2}, {"title": "Subfamilies.", "content": "The clade Falconidae is composed of three main branches: the falconets and true falcons, the caracaras, and the forest falcons. Differences exist between authorities in how these are grouped into subfamilies. Also, the placement of the laughing falcon (\"Herpetotheres\") and the spot-winged falconet (\"Spiziapteryx\") varies. One common approach uses two subfamilies Polyborinae and Falconinae. The first contains the caracaras, forest falcons, and laughing falcon. All species in this group are native to the Americas. The composition of Falconidae is disputed, and Polyborninae is not featured in the American Ornithologists' Union checklists for North and South American birds that are produced by its Classification Committees (NACC and SACC). The Check-list of North American Birds considers the laughing falcon a true falcon (Falconinae) and replaces Polyborinae with Caracarinae and Micrasturinae. On the other hand, the Check-list of South American Birds classifies all caracaras as true falcons and puts the laughing falcon and forest falcons into the subfamily Herpetotherinae. Based on genetic research from the late 1990s to 2015, Boyd uses three subfamilies. He places the laughing falcon (\"Herpetotheres\") with the forest falcons (\"Micrastur\") into Herpetotherinae (similar to SACC). Caracarinae is separate (similar to NACC), but also contains the spot-winged falconet (\"Spiziapteryx\"). The other falcons are placed in Falconinae. Falconinae, in its traditional classification, contains the falcons, falconets, and pygmy falcons. Depending on the authority, Falconinae may also include the caracaras and/or the laughing falcon.

This allows Arabic variants of the instrument to have more room for the installation of extreme bass and treble strings. Kanuns manufactured in Turkey generally feature 26 courses of strings, with three strings per course in the case of all regional variants. Contemporary Arabic designs use Nylon or PVC strings that are stretched over the bridge poised on fish-skins as described on one end, and attached to wooden tuning pegs at the other end. Ornamental sound holes called \"kafes\" are a critical component of what constitutes the accustomed timbre of qanun. However, they normally occupy different locations on the soundboard of Turkish kanuns compared to Arabic qanuns, and may also vary in shape, size and number depending on geography or personal taste. The dimensions of a Turkish kanun are typically 95 to 100 cm (37–39\") in length, 38 to 40 cm (15–16\") in width, and 4 to 6 cm (1.5–2.3\") in height. In contrast, an Arabic qanun measures a bit larger as mentioned. Qanun is played on the lap while sitting or squatting, or sometimes on trestle support, by plucking the strings with two tortoise-shell picks (one for each hand) or with fingernails, and has a standard range of three and a half octaves from A2 to E6 that can be extended down to F2 and up to G6 in the case of Arabic designs. The instrument also features special metallic levers or latches under each course called \"mandals\". These small levers, which can be raised or lowered quickly by the performer while the instrument is being played, serve to slightly change the pitch of a particular course by altering effective string lengths.", "section_level": 1}, {"title": "Tuning and temperament.", "content": "On the regular diatonically tuned qanun, \"mandal\" technology was first implemented, according to Turkish musicologist Rauf Yekta, some 30 years prior to his submission of his invited monograph on Turkish Music to the 1922 edition of Albert Lavignac's \"Encyclopédie de la Musique et Dictionnaire du Conservatoire\". Levantine qanuns, prior to that time, remained rather inflexible and cumbersome to perform on (especially as demanding modulations/transpositions came into vogue that were increasingly emulating Western tonality and key changes), requiring the player to use the fingernail of the thumb to depress on the leftmost ends of the courses to achieve on-the-fly intervallic alterations. With the advent of electronic tuners some decades later, standardization of the placement of \"reference mandals\" on the qanun began. While Armenian kanuns now employ only equidistant half-tones and Arabic qanuns exact quarter-tones as a result, Turkish kanun-makers went so far as dividing the electroacoustically referenced equal-tempered semitone of 100 cents into 6 equal parts, yielding – for all intents and purposes – 72 equal divisions (or commas) of the octave pitch resolution. Not all pitches of 72-tone equal temperament are available on the Turkish kanun, however, since kanun-makers affix mandals that only accommodate modulations/transpositions popularly demanded by performers. This has subsequently led to the familiar interrupted and irregular pattern of mandals on the Turkish kanun becoming a visual guide for players, in facilitating modal and intonational navigation on an instrument which is ordinarily bereft of pitch markers. Some kanun-makers may also choose to divide the semitone distance from the nut of the lower registers into 7 parts instead for microtonal subtlety (and the highest registers, conversely, into 5 parts due to spacing constraints); but do so at the expense of octave equivalences. Despite the mentioned discrepancies, hundreds of mandal configurations are at the player's disposal when performing on an ordinary Turkish kanun. On the other hand, the nowadays widespread application of equidistant 24-tones on Arabic and 72-tones on Turkish qanun models presents an ongoing source of controversy. This is particularly in regards to how adequate such Eurocentric octave divisions are in faithfully reproducing the traditionally or classically understood fluid pitches and inflexions of Arabic music or Ottoman classical music scales. Pitch measurement analyses of relevant audio recordings reveal that, equal temperaments based on bike-chained \"multiples of twelve\" are essentially not compatible with authentic Middle Eastern performances; substantiating the notion instruments strictly based on them would clash audibly with a justly tuned/intoned tanbur, oud, ney, or kemenche. Alternative tuning approaches for the qanun thus also exist. Turkish music theorist Ozan Yarman has proposed, for example, an academical 79-tone temperament for the expression within tolerable error-margins of Maqamat / Makamlar / Dastgaha at all pitch levels, that was implemented by the renowned late luthier Ejder Güleç (1939–2014) on a Turkish kanun. Likewise, the late Swiss-French qānūn performer Julien Jalâl Ed-Dine Weiss (1953–2015), who was critical of the tuning deficiency of Eurocentric octave divisions in approximating just intervals, is known to have conceived, since 1990, a number of prototypes that were entirely based on low prime-limit or simple integer ratio Pythagorean and harmonic intervals; which were once again built, on instructions from Weiss, by Ejder Güleç.", "section_level": 1}, {"title": "External links.", "content": "", "section_level": 1}], "src_summary": "The qanun, kanun, ganoun or kanoon (; ;, \"qanon\";, \"qānūn\"; ; ; ; ) is a string instrument played either solo, or more often as part of an ensemble, in much of the Middle East, North Africa, West Africa, Central Asia, and southeastern regions of Europe.

With a spectrum of physical variation in the peoples, Belgian authorities legally mandated ethnic affiliation in the 1920s, based on economic criteria. Formal and discrete social divisions were consequently imposed upon ambiguous biological distinctions. To some extent, the permeability of these categories in the intervening decades helped to reify the biological distinctions, generating a taller elite and a shorter underclass, but with little relation to the gene pools that had existed a few centuries ago. The social categories are thus real, but there is little if any detectable genetic differentiation between Hutu and Tutsi. Tishkoff et al.

In Rwanda, this led to the \"Social revolution\" and Hutu violence against Tutsis. Tens of thousands of Tutsis were killed and many others fled to neighboring countries, such as Burundi, Uganda and expanding the Banyamulenge Tutsi ethnic group in the South Kivu region of the Belgian Congo. Later, exiled Tutsis from Burundi invaded Rwanda, prompting Rwanda to close its border to Burundi. In Burundi, a campaign of genocide was conducted against the Hutu population in 1972, and an estimated 100,000 Hutus died. In 1993, Burundi's first democratically elected president, Melchior Ndadaye, who was Hutu, was believed to be assassinated by Tutsi officers, as was the person constitutionally entitled to succeed him. This sparked a genocide in Burundi between Hutu political structures and the Tutsi military, in which an estimated 500,000 Burundians died. There were many mass killings of Tutsis and moderate Hutus; these events were deemed to be a genocide by the United Nations International Commission of Inquiry for Burundi.

The region was part of Poland during the reign of the first Polish rulers Mieszko I and Bolesław I the Brave. The first recorded mention of the town comes from 1170 when the Pomeranian duke Casimir I granted a few villages and oversight of a church in the town to settlers from Lund in Sweden. It was part of the Duchy of Pomerania, which separated itself from Poland as a result of the fragmentation of Poland. In 1504, Johannes Bugenhagen moved to the town and became Rector of the local school. On 13 December 1534 a diet was assembled in the town, where the Dukes Barnim XI and Philip I as well as the nobility officially introduced Lutheranism to Pomerania, against the vote of Erasmus von Manteuffel-Arnhausen, Prince-Bishop of Cammin. In the following month Bugenhagen drafted the new church order (Kirchenordnung), founding the Pomeranian Lutheran church (today's Pomeranian Evangelical Church). As a dowager, Sophia of Schleswig-Holstein-Sonderburg (1579–1658), widow of Philip II, Duke of Pomerania, lived in Treptow. Sophia's dower was a former nunnery, which she converted into a palace. While in Swedish service and thereafter Duke Francis Henry of Saxe-Lauenburg spent a lot of time with Duchess dowager Sophia in Treptow. Sophia's and Francis Henry's fathers were cousins. On 13 December 1637 Francis Henry and Marie Juliane of Nassau-Siegen (1612–1665) married in Treptow. Their first child was born in Treptow in 1640. Francis Henry also served Sophia as administrator of the estates pertaining to her dower. In 1637 Philip II died leaving the Pomeranian ducal house extinct. At this point the duchy came under Swedish occupation with the Brandenburgian electors claiming succession in Pomerania. It was not until 1648 that the electors annexed the central and eastern part of the former duchy, which formed the newly established province of Pomerania. In 1750 the local palace was refurbished in classicist style for General Frederick Eugene of Württemberg, who resided there – with interruptions – until 1763. In the late 18th century, thanks to Polish noblewoman and writer Maria Wirtemberska née Czartoryska, the cultural life of the town was revived. She lived in the Trzebiatów Palace, and her early works and translations were created here. The Polish painter Jan Rustem visited her several times, and his paintings were part of the palace's art collection. The palace now houses a public library, founded in 1946 and named after Maria Wirtemberska née Czartoryska since 1999. With the end of the Holy Roman Empire in 1806, Brandenburg-Pomerania, already since 1618 ruled in personal union with Ducal Prussia (Kingdom since 1701), also legally merged into Prussia and the different German confederacies and empires of which it formed part since. Near the end of the World War II, in February 1945, despite the approaching front, the German authorities did not allow for the evacuation of the town's population. It was not until March 4 that the order to evacuate was issued, the day after the German army left the town, leaving the defenseless civilian population at the mercy of the approaching Soviet Army. After the war the central and eastern part of Western Pomerania, including Trzebiatów, became part of Poland.

Breton coined the term for his book \"Anthology of Black Humor\" (\"Anthologie de l'humour noir\"), in which he credited Jonathan Swift as the originator of black humor and gallows humor (particularly in his pieces \"Directions to Servants\" (1731), \"A Modest Proposal\" (1729), \"Meditation Upon a Broomstick\" (1710), and in a few aphorisms).

The paperback was one of the first American anthologies devoted to the concept of black humor as a literary genre. With the paperback, Friedman labeled as \"black humorists\" a variety of authors, such as J. P.

Among the writers labeled as black humorists by journalists and literary critics are today also Roald Dahl, Kurt Vonnegut, Warren Zevon, Christopher Durang, and Philip Roth. The motive for applying the label black humorist to all the writers cited above is that they have written novels, poems, stories, plays, and songs in which profound or horrific events were portrayed in a comic manner.

It insists that it cannot be affected by the traumas of the external world; it shows, in fact, that such traumas are no more than occasions for it to gain pleasure.\" Some other sociologists elaborated this concept further. At the same time, Paul Lewis warns that this \"relieving\" aspect of gallows jokes depends on the context of the joke: whether the joke is being told by the threatened person themselves or by someone else. Black comedy has the social effect of strengthening the morale of the oppressed and undermines the morale of the oppressors. According to Wylie Sypher, \"to be able to laugh at evil and error means we have surmounted them.\" Black comedy is a natural human instinct and examples of it can be found in stories from antiquity. Its use was widespread in middle Europe, from where it was imported to the United States. It is rendered with the German expression \"Galgenhumor\". The concept of gallows humor is comparable to the French expression \"rire jaune\" (lit. \"yellow laughing\"), which also has a Germanic equivalent in the Belgian Dutch expression \"groen lachen\" (lit. \"green laughing\"). Italian comedian Daniele Luttazzi discussed gallows humour focusing on the particular type of laughter that it arouses (\"risata verde\" or \"groen lachen\"), and said that grotesque satire, as opposed to ironic satire, is the one that most often arouses this kind of laughter. In the Weimar era \"Kabaretts\", this genre was particularly common, and according to Luttazzi, Karl Valentin and Karl Kraus were the major masters of it. Black comedy is common in professions and environments where workers routinely have to deal with dark subject matter. This includes police officers, firefighters, ambulance crews, military personnel and funeral directors, where it is an acknowledged coping mechanism. Outsiders can often react negatively to discovering this humor; as a result, there is an understanding within these professions that these jokes should not be shared with the wider public.

Although the resulting grape did not entirely attain these two qualities, it nonetheless became widely planted across many of the German wine-producing regions. By the 1970s, Müller-Thurgau had become Germany's most-planted grape. A possible reason for the popularity of this varietal is that it is capable of being grown in a relatively wide range of climates and soil types. Many of these vines were planted on flat areas that were not particularly suitable for growing other wine grapes because it was more profitable than sugar beet, which was the main alternative crop in those locations. The vines mature early and bring large yield quantities, and are less demanding as to planting site than for example Riesling. Müller-Thurgau wines are mild due to low acidic content, but nevertheless fruity. The wines may be drunk while relatively young, and with few exceptions are not considered to improve with age. These facts meant that Müller-Thurgau provided an economical way to cheaply produce large amounts of medium sweet German wines, such as Liebfraumilch and Piesporter, which were quite popular up until the 1980s. The turning point in Müller-Thurgau's growth however was the winter of 1979, when on 1 January there was a sharp fall in temperatures, to 20 °F (−7 °C) in many areas, which devastated most of the new varieties, but did not affect the varieties such as Riesling which have much more hardy stems, after hundreds of years of selection. In the decades since then, the winemakers have begun to grow a wider variety of vines, and Müller-Thurgau is now less widely planted in Germany than Riesling, although still significant in that country and worldwide.

After the National Socialists (or Nazis) closed all private schools, he switched to a public Catholic school in Cologne where, in 1937, he received his Abitur, the German equivalent of a high school diploma. In the same year, he fulfilled his duty for the Reichsarbeitsdienst and spent the 1937/1938 winter semester studying pedagogy at the Hochschule für Lehrerausbildung (lit. University for Teacher Training) in Bonn. He began studying Music Education, Musicology and Composition in the winter of 1938 at the University for Music in Cologne. In 1940, he was drafted in the Wehrmacht (the German Army) but was released in 1942 due to a severe skin illness. After he returned to his studies, he didn't receive a degree until 1947 due to the ending of the war. However, he was already busy as a free-lance composer in 1946, predominantly for radio. From 1948 to 1950, he was a participant in the Kranichsteiner/Darmstädter Ferienkursen für Neue Musik (lit. Kranichstein/Darmstadt Vacation Course for New Music) where he studied under René Leibowitz and Wolfgang Fortner, among others. In 1957, he received a scholarship to spend time at the German Academy Villa Massimo in Rome. He also assumed the position of Professor of Composition (from Frank Martin) as well as Film and Broadcast Music at the Cologne Music University. In the 60s, he received more attention and success as a composer (including a second scholarship to the Villa Massimo in 1963 and a fellowship in the Academy of Arts, Berlin), especially after his opera \"Die Soldaten\" (The Soldiers) finally premiered in 1965. The opera had previously not been performed due to the enormous number of people required and the musical difficulty—the Cologne Opera had considered it \"unspielbar\" (not performable). The composer's depressive tendencies increased to a more physical level, compounded by a quickly deteriorating eye problem.

His affection for jazz can sometimes be heard in some of his compositions (more so in his Violin Concerto or Trumpet Concerto). In contrast to the so-called Darmstadt School (Stockhausen, Boulez, Nono, etc.), Zimmermann did not make a radical break with tradition.

The combination and overlapping of layers of musical material from various time periods (from Medieval to Baroque and Classical to Jazz and Pop music) using advanced musical techniques is characteristic of \"Klangkomposition\". Zimmermann's use of this technique ranged from the embedding of individual musical quotes (seen somewhat in his orchestral work \"Photoptosis\") to pieces that are built entirely as a collage (the ballet \"Musique pour les soupers du Roi Ubu\").

A fortified town arose around the monastery, which was destroyed in the course of the Hussite Wars after the 1426 Battle of Aussig. In the late 15th century, queen consort Joanna of Rožmitál, wife of King George of Poděbrady, had a castle erected on the ruins. The name \"Teplice\" is derived from the Old Czech, meaning \"hot spring\". Teplice figures in the history of the Thirty Years' War, when it was a possession of the Protestant Bohemian noble Vilém Kinský, who was assassinated together with Generalissimo Albrecht von Wallenstein at Cheb in 1634. The Habsburg emperor Ferdinand II thereafter enfeoffed castle and town to his general Johann von Aldringen, who nevertheless was killed in battle in the same year, and Teplice fell to his sister Anna Maria von Clary-Aldringen. Consequently, and until 1945, Teplitz Castle was the primarily seat of the princely House of Clary-Aldringen. After the Thirty Years' War, the devastated town was the destination of many German settlers. After a blaze in 1793, large parts of the town were rebuilt in a Neoclassical style. The health resort was a popular venue for wealthy bourgeois like the poet Johann Gottfried Seume, who died on his stay in 1810, or Ludwig van Beethoven, who met here with Johann Wolfgang von Goethe in 1812; as well as for European monarchs.

Price called the first stage the \"Cthulhu Mythos proper.\" This stage was formulated during Lovecraft's lifetime and was subject to his guidance. The second stage was guided by August Derleth who, in addition to publishing Lovecraft's stories after his death, attempted to categorize and expand the Mythos.", "section_level": 1}, {"title": "First stage.", "content": "An ongoing theme in Lovecraft's work is the complete irrelevance of mankind in the face of the cosmic horrors that apparently exist in the universe. Lovecraft made frequent references to the \"Great Old Ones\", a loose pantheon of ancient, powerful deities from space who once ruled the Earth and have since fallen into a deathlike sleep. While these monstrous deities were present in almost all of Lovecraft's published work (his second short story \"Dagon\", published in 1919, is considered the start of the mythos), the first story to really expand the pantheon of Great Old Ones and its themes is \"The Call of Cthulhu\", which was published in 1928. Lovecraft broke with other pulp writers of the time by having his main characters' minds deteriorate when afforded a glimpse of what exists outside their perceived reality. He emphasized the point by stating in the opening sentence of the story that \"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents.\" Writer Dirk W. Mosig notes that Lovecraft was a \"mechanistic materialist\" who embraced the philosophy of \"cosmic indifference\" (Cosmicism). Lovecraft believed in a purposeless, mechanical, and uncaring universe. Human beings, with their limited faculties, can never fully understand this universe, and the cognitive dissonance caused by this revelation leads to insanity, in his view. There have been attempts at categorizing this fictional group of beings. Phillip A. Schreffler argues that by carefully scrutinizing Lovecraft's writings, a workable framework emerges that outlines the entire \"pantheon\"from the unreachable \"Outer Ones\" (e.g., Azathoth, who occupies the centre of the universe) and \"Great Old Ones\" (e.g., Cthulhu, imprisoned on Earth in the sunken city of R'lyeh) to the lesser castes (the lowly slave shoggoths and the Mi-go). David E. Schultz, however, believes that Lovecraft never meant to create a canonical Mythos but rather intended his imaginary pantheon to serve merely as a background element. Lovecraft himself humorously referred to his Mythos as \"Yog Sothothery\" (Dirk W. Mosig coincidentally suggested the term \"Yog-Sothoth Cycle of Myth\" be substituted for \"Cthulhu Mythos\"). At times, Lovecraft even had to remind his readers that his Mythos creations were entirely fictional. The view that there was no rigid structure is expounded upon by S. T. Joshi, who said Price, however, believed that Lovecraft's writings could at least be divided into categories and identified three distinct themes: the \"Dunsanian\" (written a similar style as Lord Dunsany), \"Arkham\" (occurring in Lovecraft's fictionalized New England setting), and \"Cthulhu\" (the cosmic tales) cycles. Writer Will Murray noted that while Lovecraft often used his fictional pantheon in the stories he ghostwrote for other authors, he reserved Arkham and its environs exclusively for those tales he wrote under his own name. Although the Mythos was not formalized or acknowledged between them, Lovecraft did correspond and share story elements with other contemporary writers including Clark Ashton Smith, Robert E. Howard, Robert Bloch, Frank Belknap Long, Henry Kuttner, Henry S. Whitehead, and Fritz Leibera group referred to as the \"Lovecraft Circle.\" For example, Robert E. Howard's character Friedrich Von Junzt reads Lovecraft's \"Necronomicon\" in the short story \"The Children of the Night\" (1931), and in turn Lovecraft mentions Howard's \"Unaussprechlichen Kulten\" in the stories \"Out of the Aeons\" (1935) and \"The Shadow Out of Time\" (1936). Many of Howard's original unedited \"Conan\" stories also involve parts of the Cthulhu Mythos.", "section_level": 2}, {"title": "Second stage.", "content": "Price denotes the second stage's commencement with August Derleth, with the principal difference between Lovecraft and Derleth being Derleth's use of hope and development of the idea that the Cthulhu mythos essentially represented a struggle between good and evil. Derleth is credited with creating the \"Elder Gods.\" He stated: Price believes that the basis for Derleth's system is found in Lovecraft: \"Was Derleth's use of the rubric 'Elder Gods' so alien to Lovecraft's in \"At the Mountains of Madness\"? Perhaps not. In fact, this very story, along with some hints from \"The Shadow over Innsmouth\", provides the key to the origin of the 'Derleth Mythos'. For in \"At the Mountains of Madness\" is shown the history of a conflict between interstellar races, first among them the Elder Ones and the Cthulhu-spawn. Derleth himself believed that Lovecraft wished for other authors to actively write about the Mythos as opposed to it being a discrete plot device within Lovecraft's own stories. Derleth expanded the boundaries of the Mythos by including any passing reference to another author's story elements by Lovecraft as part of the genre. Just as Lovecraft made passing reference to Clark Ashton Smith's \"Book of Eibon\", Derleth in turn added Smith's Ubbo-Sathla to the Mythos. Derleth also attempted to connect the deities of the Mythos to the four elements (\"air\", \"earth\", \"fire\", and \"water\"), creating new beings representative of certain elements in order to legitimize his system of classification. Derleth created \"Cthugha\" as a sort of fire elemental when a fan, Francis Towner Laney, complained that he had neglected to include the element in his schema. Laney, the editor of \"The Acolyte\", had categorized the Mythos in an essay that first appeared in the Winter 1942 issue of the magazine. Impressed by the glossary, Derleth asked Laney to rewrite it for publication in the Arkham House collection \"Beyond the Wall of Sleep\" (1943). Laney's essay (\"The Cthulhu Mythos\") was later republished in \"Crypt of Cthulhu #32\" (1985).

His father was baptized as a Lutheran, while his mother was from a family of secular Jews. He began writing short stories in 1924 and the following year became drama critic for a Berlin newspaper. His first literary works were published in 1925. Mann's early life was troubled. His homosexuality often made him the target of bigotry, and he had a difficult relationship with his father. After only a short time in various schools, he travelled with his sister Erika Mann, a year older than himself, around the world, visiting the US in 1927; they reported on the trip in essays published as a collaborative travelogue entitled \"Rundherum\" in 1929. In 1924 he had become engaged to his childhood friend Pamela Wedekind, the eldest daughter of the playwright Frank Wedekind, who was also a close friend of his sister Erika. The engagement was broken off in January 1928. He travelled with Erika to North Africa in 1929. Around this time they made the acquaintance of Annemarie Schwarzenbach, a Swiss writer and photographer, who remained close to them for the next few years. Klaus made several trips abroad with Annemarie, the final one to a Soviet writers' congress in Moscow in 1934. Since his young adulthood, Klaus was using drugs, mostly opiates, to which he later became heavily addicted. His diaries document an attempted morphine-injection in 1933 when Hitler took power. Initially, the aspiring writer used opium, Eukodal and later heroin to possibly increase his creative energy, as this was often the case for artists and intellectuals in literary circles at the time. He underwent drug detoxification in Budapest during his frantic travels and at the Kilchberg Sanatorium in Switzerland. After 1936, his drug use and sexual escapades became excessive during his stay in New York. In 1932 Klaus wrote the first part of his autobiography, which was well received until Hitler came to power. In 1933 Klaus participated with Erika in a political cabaret, called \"Die Pfeffermühle\" (\"The Pepper-Mill\"), which came to the attention of the Nazi regime. To escape prosecution he left Germany in March 1933 for Paris, later visiting Amsterdam and Switzerland, where his family had a house. Also in 1933, Klaus Mann and Annemarie Schwarzenbach, together with Fritz Landshoff and Dutch publisher Emanuel Querido, founded \"Die Sammlung\", a literary magazine, first published in September 1933 in Amsterdam. It was primarily affiliated with a number of influential German writers who fled from the Hitler regime during the first years of the establishment and consolidation of Nazi rule. The magazine was funded by the wealthy Annemarie Schwarzenbach, and Klaus Mann served as its editor-in-chief from 1933 to 1935, when \"Die Sammlung\"'s activity ceased. Klaus Mann not only played an important role in the consolidation of the German \"Exilliteratur\" but also communicated with authors who remained in Germany after 1933. In a letter exchange with Gottfried Benn, whose ambivalence towards Nazi rule was well known, Klaus expressed concern about his continued membership in the national German academy of writers, pointing out the moral dilemma it posed, even urging him to leave the country to join the German intellectuals in exile. In November 1934 Klaus was stripped of German citizenship by the Nazi regime. He became a Czechoslovak citizen. In 1936, he moved to the United States, living in Princeton, New Jersey, and New York. In the summer of 1937, he met his partner for the rest of the year Thomas Quinn Curtiss, who was later a longtime film and theater reviewer for \"Variety\" and the \"International Herald Tribune\". In 1940 Klaus Mann founded another literary magazine for German writers living in exile in the United States, \"Decision\". It lasted for only a year. During that time, he also lived at his father's house in Pacific Palisades when he was unable to support himself financially. Mann became a US citizen in 1943. The process of naturalization was delayed because of an investigation the FBI conducted into Klaus Mann's political and sexual activities; he was openly gay but not an adherent of marxist ideologies. Throughout his life in the US, he identified himself as a liberal antifascist and cosmopolitan. In World War II, he served as a Staff Sergeant of the 5th US Army in Italy. In summer 1945, he was sent by the \"Stars and Stripes\" to report from Postwar-Germany. Mann's most famous novel, \"Mephisto\", was written in 1936 and first published in Amsterdam. The novel is a thinly-disguised portrait of his former brother-in-law, the actor Gustaf Gründgens. The literary scandal surrounding it made Mann posthumously famous in West Germany, as Gründgens' adopted son brought a legal case to have the novel banned after its first publication in West Germany in the early 1960s. After seven years of legal hearings, the West German Supreme Court banned it by a vote of three to three, although it continued to be available in East Germany and abroad. The ban was lifted and the novel published in West Germany in 1981. Mann's novel \"Der Vulkan\" is one of the 20th century's most famous novels about German exiles during World War II.

Higher grades are intended to represent a lower probability of default. Agencies do not attach a hard number of probability of default to each grade, preferring descriptive definitions such as: \"the obligor's capacity to meet its financial commitment on the obligation is extremely strong,\" or \"less vulnerable to non-payment than other speculative issues...\" (Standard and Poors' definition of an AAA-rated and a BB-rated bond respectively). However, some studies have estimated the average risk and reward of bonds by rating. One study by Moody's claimed that over a \"5-year time horizon\" bonds it gave its highest rating (Aaa) to had a \"cumulative default rate\" of 0.18%, the next highest (Aa2) 0.28%, the next (Baa2) 2.11%, 8.82% for the next (Ba2), and 31.24% for the lowest it studied (B2). (See \"Default rate\" in \"Estimated spreads and default rates by rating grade\" table to right.) Over a longer period, it stated \"the order is by and large, but not exactly, preserved\". Another study in \"Journal of Finance\" calculated the additional interest rate or \"spread\" corporate bonds pay over that of \"riskless\" US Treasury bonds, according to the bonds' rating. (See \"Basis point spread\" in table to right.) Looking at rated bonds for 1973–89, the authors found a AAA-rated bond paid 43 \"basis points\" (or 43/100 of a percentage point) over a US Treasury bond (so that it would yield 3.43% if the Treasury yielded 3.00%). A CCC-rated \"junk\" (or speculative) bond, on the other hand, paid over 7% (724 basis points) more than a Treasury bond on average over that period. Different rating agencies may use variations of an alphabetical combination of lowercase and uppercase letters, with either plus or minus signs or numbers added to further fine-tune the rating (see colored chart). The Standard & Poor's rating scale uses uppercase letters and pluses and minuses. The Moody's rating system uses numbers and lowercase letters as well as uppercase. While Moody's, S&P and Fitch Ratings control approximately 95% of the credit ratings business, they are not the only rating agencies. DBRS's long-term ratings scale is somewhat similar to Standard & Poor's and Fitch Ratings with the words high and low replacing the + and −. It goes as follows, from excellent to poor: AAA, AA (high), AA, AA (low), A (high), A, A (low), BBB (high), BBB, BBB (low), BB (high), BB, BB (low), B (high), B, B (low), CCC (high), CCC, CCC (low), CC (high), CC, CC (low), C (high), C, C (low) and D. The short-term ratings often map to long-term ratings though there is room for exceptions at the high or low side of each equivalent. S&P, Moody's, Fitch and DBRS are the only four ratings agencies that are recognized by the European Central Bank (ECB) for determining collateral requirements for banks to borrow from the central bank. The ECB uses a first, best rule among the four agencies that have the designated ECAI status, which means that it takes the highest rating among the four agencies – S&P, Moody's, Fitch and DBRS – to determine haircuts and collateral requirements for borrowing.

According to the leaders of Kett's Rebellion (1549), \"all bond men may be made free, for God made all free with his precious blood-shedding.\" In the 17th century, English common law judge Sir Edward Coke revived the idea of rights based on citizenship by arguing that Englishmen had historically enjoyed such rights. The Parliament of England adopted the English Bill of Rights in 1689. It was one of the influences drawn on by George Mason and James Madison when drafting the Virginia Declaration of Rights in 1776. The Virginia declaration is the direct ancestor and model for the U.S. Bill of Rights (1789). The removal by legislation of a civil right constitutes a \"civil disability\". In early 19th century Britain, the phrase \"civil rights\" most commonly referred to the issue of such legal discrimination against Catholics. In the House of Commons support for civil rights was divided, with many politicians agreeing with the existing civil disabilities of Catholics. The Roman Catholic Relief Act 1829 restored their civil rights. In the 1860s, Americans adapted this usage to newly freed blacks. Congress enacted civil rights acts in 1866, 1871, 1875, 1957, 1960, 1964, 1968, and 1991.", "section_level": 1}, {"title": "Protection of rights.", "content": "T. H.

Civil and political rights need not be codified to be protected. However, most democracies worldwide do have formal written guarantees of civil and political rights. Civil rights are considered to be natural rights. Thomas Jefferson wrote in his \"A Summary View of the Rights of British America\" that \"a free people [claim] their rights as derived from the laws of nature, and not as the gift of their chief magistrate.\" The question of to whom civil and political rights apply is a subject of controversy. Although in many countries citizens have greater protections against infringement of rights than non-citizens, civil and political rights are generally considered to be universal rights that apply to all persons.

Rather than carrying an internal combustion engine or batteries, or connecting to overhead powerlines, a gyrobus carries a large flywheel that is spun at up to 3,000 RPM by a \"squirrel cage\" motor. Power for charging the flywheel was sourced by means of three booms mounted on the vehicle's roof, which contacted charging points located as required or where appropriate (at passenger stops en route, or at terminals, for instance). To obtain tractive power, capacitors would excite the flywheel's charging motor so that it became a generator, in this way transforming the energy stored in the flywheel back into electricity. Vehicle braking was electric, and some of the energy was recycled back into the flywheel, thereby extending its range. Fully charged, a gyrobus could typically travel as far as on a level route at speeds of up to, depending on vehicle batch (load), as top speeds varied from batch to batch. The installation in Yverdon-les-Bains (Switzerland) sometimes saw vehicles needing to travel as far as on one charge, although it is not known how well they performed towards the upper end of that distance. Charging a flywheel took between 30 seconds and 3 minutes; in an effort to reduce the charge time, the supply voltage was increased from 380 volts to 500 volts. Given the relatively restricted range between charges, it is likely that several charging stops would have been required on longer routes, or in dense urban traffic. It is not clear whether vehicles that require such frequent delays would have been practical and/or suitable for modern-day service applications. The demonstrator was first displayed (and used) publicly in summer 1950 and, to promote the system, this vehicle continued to be used for short periods of public service in a myriad of locations at least until 1954. In 1979, General Electric was awarded a $5 million four-year contract by the United States government, the Department of Energy and the Department of Transportation, to develop a prototype flywheel bus. In the 1980s, Volvo briefly experimented with using flywheels charged by a small diesel engine and recharged via braking energy. This was eventually dumped in favour of using hydraulic accumulators. During the 1990s, the Dutch Centre for Concepts in Mechatronics had developed a flywheel for both mobile and stationary applications. In 2005, the Center for Transportation and the Environment, working with the University of Texas at Austin, Center for Electromechanics, Test Devices, Inc., and DRS Technologies sought funding for the development of a prototype gyrobus.", "section_level": 1}, {"title": "Early commercial service.", "content": "The first full commercial service began in October 1953, linking the Swiss communities of Yverdon-les-Bains and Grandson. However, this was a route with limited traffic potential, and although technically successful it was not commercially viable. Services ended in late October 1960, and neither of the two vehicles (nor the demonstrator) survived. The next system to open was in Léopoldville in Belgian Congo (now Kinshasa in the Democratic Republic of the Congo). Here there were 12 vehicles (although apparently some reports suggest 17), which operated over four routes, with recharging facilities being provided about every. These were the largest of the gyrobuses, being in length, weighing, carrying up to 90 passengers, and having a maximum speed of. There were major problems related to excessive \"wear and tear\". One significant reason for this was that drivers often took shortcuts across unpaved roads, which after rains became nothing more than quagmires. Other problems included breakage of gyro ball bearings, and high humidity resulting in traction motor overload. The system's demise, however, came because of high energy consumption. The bus operator deemed that 3.4 kWh/km per gyrobus was unaffordable, so closure came in the summer of 1959 with the gyrobuses being abandoned and replaced with diesel buses. The third location to use gyrobuses commercially was Ghent, Belgium. Three gyrobuses started operation in late summer 1956 on a route linking Ghent and Merelbeke. The flywheel was in the center of the bus, spanning almost the whole width of the vehicle, and having a vertical axis of rotation. The Ghent to Merelbeke route was intended to be the first of a proposed multi-route network; instead, its gyrobuses stayed in service for only three years, being withdrawn late autumn 1959. The operator considered them unreliable, \"spending more time off the road than on\", and that their weight damaged road surfaces. They were also considered to be energy hungry, consuming 2.9 kWh/km—compared with between 2.0 kWh/km and 2.4 kWh/km for trams with much greater capacity. One of Ghent's gyrobuses has been preserved and restored, and is displayed at the VLATAM-museum in Antwerp.

Before the Convention entered into force in 1963, there were already indications that the matter of national sovereignty would complicate the full implementation of the organisation's founding mission. The first European plan for a harmonised air traffic control (ATC) system, proposed in 1962, was beset by the refusal of both France and Britain to comply, largely due to reasons closely linked with their national military airspace control. The other four original members (the Federal Republic of Germany, Belgium, the Netherlands and Luxembourg) agreed in 1964 to set up a single international air traffic control centre to manage their upper airspace, settling in the Dutch city of Maastricht. The European Parliament at the time expressed concern about the lack of clear intergovernmental agreements to ensure common air traffic control services across the continent. In 1979, EUROCONTROL signed a working cooperation agreement with the European Commission, attempting to create a synergy of EUROCONTROL's technical expertise and EU's regulatory authorities. Several initiatives originating in this period become a lasting element of the organisation, such as the EUROCONTROL forecasting service, which became STATFOR, as well as the Aeronautical Information Service. By 1986, the pressures on the European ATC network was so big that a new, wider mandate was already being considered for EUROCONTROL, with much of the initiative coming from ECAC’s Ministers of Transport. Subsequently, ECAC urged all of its member states to join EUROCONTROL. A revised EUROCONTROL Convention was signed in 1997, renewing the organisation's optimism for greater political support, surpassing the original vision of the 1960 Convention. In June 1998, Eurocontrol, the European Space Agency (ESA) and the European Commission (EC) also signed an agreement formalising cooperation in the realm of satellite navigation systems and services. In 1999 the European Commission presented its plan for a Single European Sky (SES) to the European Parliament, followed by two High Level Groups (HLG). The HLG reports on SES led to the establishment of the European Aviation Safety Agency (EASA) and reinforced the European Commission's role as the sole European aviation safety regulator, while acknowledging EUROCONTROL's technical expertise in the implementation of said regulations. The early 2000s were marred by several fatal accidents in Europe, such as the 2001 Linate Airport disaster and the 2002 Überlingen mid-air collision, both of which were related to air traffic navigation shortcomings. The pressure was further compounded by the September 11 attacks, increasing the need for a rapid Europe-wide regulatory and coordinating body. By May 2003, EUROCONTROL and NATO had signed a memorandum of cooperation, followed by a similar memorandum with the European Commission in December 2003.

This point is the site of the Roman castrum, or military fortification. The city is, therefore, well-defended by steep slopes to the north, east, and west. The next step in planning the city was the surveying of the area according to the architect's plans for the city. Every important public building had its specific place, starting with the temple of Jupiter as the sacred high point from which the street network would spread. The architect, who was responsible for executing the plans for the city, next laid a longitudinal axis across the triangle 36 ̊ west of north to form the main street of the settlement. Other longitudinal streets were laid out parallel to the main street at intervals of 55 meters. The main street was then divided into sections of 66 meters (255 Roman feet), which formed the corners of 10 crossing streets. This created a series of rectangular blocks of around 50 by 60 meters.

New research, based on tiles stamped with the mark of the Vindonissa Legion, indicates some administrative dependence on Vindonissa. This would indicate that the colony reached over the Bözberg toward Frick, with the Thiersteinberg below Frick forming the eastern boundary. The western boundary, was near the mouth of the Birs, possibly marked by a border station. Early Roman cremation remains, found in 1937 by the church in Neuallschwil, show that such a post did exist on the main road north (toward Blotzheim) into Alsace.

The city possessed the typical amenities of a Roman city, an amphitheatre, a main forum, several smaller forums, an aqueduct, a variety of temples, several public baths and the largest Roman theatre north of the Alps, with 8,000 to 10,000 seats. Many of these sites are open to visitors year-round. In 250 AD, a powerful earthquake damaged a large part of the city. Shortly after, around 260 AD, Alemanni tribes and/or marauding Roman troops destroyed the city. The Romans attempted to maintain their military position by building a fortress on the Rhine, Castrum Rauracense, the walls of which are still partly intact. Augusta Raurica was resettled on a much smaller scale on the site of the castrum. These two settlements form the centers of the modern communities of Augst and Kaiseraugst. In 1442, these communities were divided along the Ergolz and rivers. The western portion was given to Basel, which became a canton of Switzerland in 1501. In 1833, Augst became part of the Canton of Basel-Land. The eastern part became part of Habsburg territories and, to differentiate between the two towns, was renamed Kaiseraugst.

Over time the generally expected garnish became the drinker's choice of a green olive or a twist of lemon peel. A dry martini is made with dry, white vermouth. By the Roaring Twenties, it became a common drink order. Over the course of the 20th century, the amount of vermouth steadily dropped. During the 1930s the ratio was 3:1 (gin to vermouth), and during the 1940s the ratio was 4:1. During the latter part of the 20th century, 6:1, 8:1, 12:1, 15:1 (the \"Montgomery\", after British Field Marshal Bernard Montgomery's supposed penchant for attacking only when in possession of great numerical superiority), or even 50:1 or 100:1 Martinis became considered the norm. A dirty martini contains a splash of olive brine or olive juice and is typically garnished with an olive. A perfect martini uses equal amounts of sweet and dry vermouth. Some martinis were prepared by filling a cocktail glass with gin, then rubbing a finger of vermouth along the rim. There are those who advocated the elimination of vermouth altogether. According to Noël Coward, \"A perfect martini should be made by filling a glass with gin, then waving it in the general direction of Italy\", Italy being a major producer of vermouth. Luis Buñuel used the dry martini as part of his creative process, regularly using it to sustain \"a reverie in a bar\". He offers his own recipe, involving Angostura bitters, in his memoir. In 1966, the American Standards Association (ASA) released K100.1-1966, \"Safety Code and Requirements for Dry Martinis\", a tongue-in-cheek account of how to make a \"standard\" dry martini. The latest revision of this document, K100.1-1974, was published by American National Standards Institute (ANSI), the successor to ASA, though it is no longer an active standard. The traditional martini comes in a number of variations. The fictional spy James Bond sometimes asked for his vodka martinis to be \"shaken, not stirred\",(although, in books by Ian Fleming, Bond asks for \"stirred, not shaken\"), following Harry Craddock's \"The Savoy Cocktail Book\" (1930), which prescribes shaking for all its martini recipes. The proper name for a shaken martini is a Bradford; however, Somerset Maugham is often quoted as saying that \"a martini should always be stirred, not shaken, so that the molecules lie sensuously on top of one another.\" A martini may also be served on the rocks; that is, with the ingredients poured over ice cubes and served in an old fashioned glass.", "section_level": 1}, {"title": "Origins and mixology.", "content": "The exact origin of the martini is unclear. A popular theory suggests it evolved from a cocktail called the Martinez served sometime in the early 1860s at the Occidental Hotel in San Francisco, which people frequented before taking an evening ferry to the nearby town of Martinez, California. Alternatively, residents of Martinez say a bartender in their town created the drink, while another source indicates that the drink was named after the town. Indeed, a \"Martinez Cocktail\" was first described in Jerry Thomas' 1887 edition of his \"Bartender's Guide, How to Mix All Kinds of Plain and Fancy Drinks\": Other bartending guides of the late 19th century contained recipes for numerous cocktails similar to the modern-day martini. For example, Harry Johnson's \"Bartenders' Manual\" (1888) listed a recipe for a drink that consisted in part of half a wine glass of Old Tom gin and a half a wine glass of vermouth. The first dry martini is sometimes linked to the name of a bartender who concocted the drink at the Knickerbocker Hotel in New York City in 1911 or 1912. The \"Marguerite Cocktail\", first described in 1904, could be considered an early form of the dry martini, because it was a 2:1 mix of Plymouth dry gin and dry vermouth, with a dash of orange bitters. During Prohibition in the United States, during the mid-20th century, the relative ease of illegal gin manufacture led to the martini's rise as the locally predominant cocktail. With the repeal of Prohibition, and the ready availability of quality gin, the drink became progressively drier. In the 1970s and '80s, the martini came to be seen as old-fashioned and was replaced by more intricate cocktails and wine spritzers, but the mid-1990s saw a resurgence in the drink and numerous new versions. Some newer drinks include the word \"martini\" or the suffix \"-tini\" in the name (e.g., appletini, peach martini, chocolate martini, Espresso Martini).

His father, the distinguished philologist Karl Wilhelm Ludwig Heyse, was a professor at the University of Berlin who had been the tutor of both Wilhelm von Humboldt's youngest son (during 1815–17) and Felix Mendelssohn (during 1819–27). His paternal grandfather Johann Christian August Heyse (21 April 1764, Nordhausen – 27 July 1829, Magdeburg), was a famous German grammarian and lexicographer. Paul Heyse's mother was Jewish. Heyse attended the renamed Friedrich-Wilhelms-Gymnasium until 1847. He was later remembered as a model student. His family connections gained him early entry to the artistic circles of Berlin, where he made the acquaintance of Emanuel Geibel, a man fifteen years his elder who was to become his literary mentor and lifelong friend, and who introduced him to his future father-in-law, the art historian and writer Franz Kugler. After leaving school Heyse began studying classical philology. He met Jacob Burckhardt, Adolph Menzel, Theodor Fontane and Theodor Storm, and in 1849 joined the \"Tunnel über der Spree\" literary group. \"Frühlingsanfang 1848\", the first of Heyse's poems to see print, expressed his enthusiasm for the recent Revolution. After a brief excursion to see the student militias he returned home without joining them, apparently out of consideration for the concerns of his parents and friends. Having studied for two years at the University of Berlin he left for Bonn in April 1849 in order to study art history and Romance languages. In 1850 he finally resolved on a career as a writer and began a dissertation under the supervision of Friedrich Diez, a pioneer of Romance philology in Germany; but when it was discovered he was conducting an affair with the wife of one of his professors he was sent back to Berlin. Heyse's first book, \"Der Jungbrunnen\" (a collection of tales and poetry) was published anonymously by his father that same year as was his tragedy \"Francesca von Rimini\". About the same time, Heyse received from the publisher Alexander Duncker a manuscript by the then-unknown Theodor Storm. Heyse's enthusiastic critique of \"Sommergeschichten und Lieder\" laid the foundations of their future friendship. In 1851 Heyse won a contest held by the members of the \"Tunnel\" for the ballad \"Das Tal von Espigno\", and his first short story, \"Marion\" (1852), was similarly honoured. It was followed in 1852 by the \"Spanisches Liederbuch\", a collection of translations of poems and folk songs by Geibel and Heyse which was to be a favourite with composers, including Robert Schumann (Opp. 74 & 138), Adolf Jensen (Op. 21) and Hugo Wolf (Lieder collection \"Spanisches Liederbuch\", 1891). Wolf also set poems from Heyse's collection \"Italienisches Liederbuch\" of 1860 (Lieder collection \"Italienisches Liederbuch\" 189296). Throughout his career Heyse worked as a translator, above all of Italian literature (Leopardi, Giusti). Several members of the \"Tunnel\" began to find its formalities and public nature distasteful, and a smaller circle, the \"Rütli\", was formed in December 1852: it included Kugler, Lepel, Fontane, Storm, and Heyse. In May 1852 Heyse was awarded a doctorate for his work on the troubadours, and a Prussian scholarship allowed him to depart for Italy to look for old Provençal manuscripts. He made friends with Arnold Böcklin and Joseph Victor von Scheffel but was banned from the Vatican library after being discovered copying passages from unpublished manuscripts. He returned to Germany in 1853, where, with the Italian landscape still fresh in his mind, he wrote the works which first made him famous: his most famous short story, \"L'Arrabbiata\" (\"The Fury\", 1853, published in 1855); and the \"Lieder aus Sorrent\" (\"Songs of Sorrento\", 1852/53).

Heyse was thus appointed professor of Romance philology, although he never taught at that city's university. After his marriage on 15 May to Margarete Kugler he arrived in Munich on 25 May 1854. At his first audience with the King, Heyse presented his verse tales, \"Hermen\", and began a productive life as one of the \"Nordlichtern\" (\"northern lights\": Geibel, Heyse and Riehl) and establishing another literary society, \"Die Krokodile\", which included Felix Dahn, Wilhelm Hertz, Hermann Lingg, Franz von Kobell, the cultural historian Wilhelm Heinrich Riehl, Friedrich Bodenstedt, and the travel writer and art patron Adolf Friedrich von Schack. In December Heyse began a long correspondence with Eduard Mörike. On 22 August 1855 Heyse's first son, Franz, was born. Heyse would have four children by his first marriage: Franz (1855–1919), Julie or Lulu (Frau Baumgarten, 1857–1928), Ernst (1859–1871) and Clara (Frau Layriz, 1861–1931). In 1859, obligations to the Kugler family led Heyse to take up a position as editor of the \"Literaturblatt zum deutschen Kunstblatt\", and he declined a tempting offer from the Grand Duke Carl Alexander von Weimar which would have involved moving to Thuringia. On 30 September 1862, his wife Margarete died in Meran of a lung illness. He completed the historical drama, \"Ludwig der Bayer\" – a Bavarian period piece which Maximilian II had long been eager to see – but its theatrical production was a failure. Nevertheless, Heyse worked throughout the 1860s on new plays, eventually achieving his greatest success with \"Kolberg\" (1865). He married Anna Schubart in 1867. Over the next three decades, Heyse continued to write prolifically. Despite a number of bereavements his life was uneventful, and his fame grew steadily until he was a world-famous figure. He was a very early opponent of naturalism, making critical references to it in print long before its influence could be felt in Germany. Younger critics who favoured naturalism made attacks on his writings, to which he replied in \"Merlin\" (1892): but their influence on the public was negligible. He was dubbed \"Dichterfürst\", prince of poetry, and he worked tirelessly to promote international understanding within Europe. In 1900, he was named an honorary citizen of Munich, and several special publications honoured his 70th birthday; and in 1910, he was made a member of the nobility, before being awarded the Nobel Prize for Literature on 10 December. He could not attend the ceremony, and was represented in Sweden by Count von Pückler. His last published works were \"Letzten Novellen\" and \"Italienischen Volksmärchen\" (1914).

This discovery, announced in 1932 and later confirmed by others, validated Paul Dirac's theoretical prediction of the existence of the positron. Anderson first detected the particles in cosmic rays. He then produced more conclusive proof by shooting gamma rays produced by the natural radioactive nuclide ThC\" (Tl) into other materials, resulting in the creation of positron-electron pairs. For this work, Anderson shared the 1936 Nobel Prize in Physics with Victor Hess. Fifty years later, Anderson acknowledged that his discovery was inspired by the work of his Caltech classmate Chung-Yao Chao, whose research formed the foundation from which much of Anderson's work developed but was not credited at the time. Also in 1936, Anderson and his first graduate student, Seth Neddermeyer, discovered the muon (or'mu-meson', as it was known for many years), a subatomic particle 207 times more massive than the electron, but with the same negative electric charge and spin 1/2 as the electron, again in cosmic rays. Anderson and Neddermeyer at first believed that they had seen the pion, a particle which Hideki Yukawa had postulated in his theory of the strong interaction. When it became clear that what Anderson had seen was \"not\" the pion, the physicist I. I. Rabi, puzzled as to how the unexpected discovery could fit into any logical scheme of particle physics, quizzically asked \"Who ordered \"that\"?\" (sometimes the story goes that he was dining with colleagues at a Chinese restaurant at the time). The muon was the first of a long list of subatomic particles whose discovery initially baffled theoreticians who could not make the confusing \"zoo\" fit into some tidy conceptual scheme.

Most require an exchange of information (such as public keys) in addition to the message over a secure channel. Such protocols, often using key-agreement protocols, have been developed with different security requirements for the secure channel, though some have attempted to remove the requirement for any secure channel at all. A public key infrastructure, such as Transport Layer Security, may harden Transmission Control Protocol against MITM attacks. In such structures, clients and servers exchange certificates which are issued and verified by a trusted third party called a certificate authority (CA). If the original key to authenticate this CA has not been itself the subject of a MITM attack, then the certificates issued by the CA may be used to authenticate the messages sent by the owner of that certificate. Use of mutual authentication, in which both the server and the client validate the other's communication, covers both ends of a MITM attack, though the default behavior of most connections is to only authenticate the server. Attestments, such as verbal communications of a shared value (as in ZRTP), or recorded attestments such as audio/visual recordings of a public key hash are used to ward off MITM attacks, as visual media is much more difficult and time-consuming to imitate than simple data packet communication. However, these methods require a human in the loop in order to successfully initiate the transaction. In a corporate environment, successful authentication (as indicated by the browser's green padlock) does not always imply secure connection with the remote server. Corporate security policies might contemplate the addition of custom certificates in workstations' web browsers in order to be able to inspect encrypted traffic. As a consequence, a green padlock does not indicate that the client has successfully authenticated with the remote server but just with the corporate server/proxy used for SSL/TLS inspection. HTTP Public Key Pinning (HPKP), sometimes called \"certificate pinning,\" helps prevent a MITM attack in which the certificate authority itself is compromised, by having the server provide a list of \"pinned\" public key hashes during the first transaction. Subsequent transactions then require one or more of the keys in the list must be used by the server in order to authenticate that transaction.

Following the accession to the throne of Suleiman I, the sultan sent an ambassador to Louis II to collect the annual tribute that Hungary had been subjected to. Louis refused to pay the annual tribute and had the Ottoman ambassador executed and sent the head to the Sultan. Louis believed that the Papal States and other Christian States including Charles V, Holy Roman Emperor would help him. This event hastened the fall of Hungary. Hungary was in a state of near anarchy in 1520 under the rule of the magnates. The king's finances were a shambles; he borrowed to meet his household expenses despite the fact that they totaled about one-third of the national income. The country's defenses weakened as border guards went unpaid, fortresses fell into disrepair, and initiatives to increase taxes to reinforce defenses were stifled. In 1521 Sultan Suleiman the Magnificent was well aware of Hungary's weakness. The Ottoman Empire declared war on the Kingdom of Hungary, Suleiman postponed his plan to besiege Rhodes and made an expedition to Belgrade. Louis failed to coordinate and gather his forces. At the same time, Hungary was unable to get assistance from other European states, which Louis had hoped for. Belgrade and many strategic castles in Serbia were captured by the Ottomans. This was disastrous for Louis' kingdom; without the strategically important cities of Belgrade and Šabac, Hungary, including Buda, was open to further Turkish conquests. After the siege of Rhodes, in 1526 Suleiman made a second expedition to subdue all of Hungary. Louis made a tactical error when he tried to stop the Ottoman army in an open field battle with a medieval army, insufficient firearms, and obsolete tactics.

SALT I froze the number of strategic ballistic missile launchers at existing levels and provided for the addition of new submarine-launched ballistic missile (SLBM) launchers only after the same number of older intercontinental ballistic missile (ICBM) and SLBM launchers had been dismantled. SALT I also limited land-based ICBMs that were in range from the northeastern border of the continental United States to the northwestern border of the continental USSR. In addition to that, SALT I limited the number of SLBM capable submarines that NATO and the United States could operate to 50 with a maximum of 800 SLBM launchers between them. If the United States or NATO were to increase that number, the USSR could respond with increasing their arsenal by the same amount. The strategic nuclear forces of the Soviet Union and the United States were changing in character in 1968. The total number of missiles held by the United States had been static since 1967 at 1,054 ICBMs and 656 SLBMs but there was an increasing number of missiles with multiple independently targetable reentry vehicle (MIRV) warheads being deployed. MIRVs carried multiple nuclear warheads, often with dummies, to confuse ABM systems, making MIRV defense by ABM systems increasingly difficult and expensive. Both sides were also permitted to increase their number of SLBM forces, but only after disassembling an equivalent number of older ICBMs or SLBM launchers on older submarines. One clause of the treaty required both countries to limit the number of deployment sites protected by an anti-ballistic missile (ABM) system to one each. The idea of this system was that it would prevent a competition in ABM deployment between the US and the Soviet Union. The Soviet Union had deployed such a system around Moscow in 1966 and the United States announced an ABM program to protect twelve ICBM sites in 1967. After 1968, the Soviet Union tested a system for the SS-9 missile, otherwise known as the R-36 missile. A modified two-tier Moscow ABM system is still used. The United States built only one ABM site to protect a Minuteman base in North Dakota where the \"Safeguard\" Program was deployed. This base was increasingly more vulnerable to attacks by the Soviet ICBMs, because of the advancement in Soviet missile technology. Negotiations lasted from November 17, 1969, until May 1972 in a series of meetings beginning in Helsinki, with the US delegation headed by Gerard C. Smith, director of the Arms Control and Disarmament Agency. Subsequent sessions alternated between Vienna and Helsinki. After a long deadlock, the first results of SALT I came in May 1971, when an agreement was reached over ABM systems. Further discussion brought the negotiations to an end on May 26, 1972, in Moscow when Richard Nixon and Leonid Brezhnev signed both the Anti-Ballistic Missile Treaty and the \"Interim Agreement Between The United States of America and The Union of Soviet Socialist Republics on Certain Measures With Respect to the Limitation of Strategic Offensive Arms\". The two sides also agreed to a number of basic principles regrading appropriate conduct. Each recognized the sovereignty of the other and agreed to the principle of non-interference while at the same seeking to promote economic, scientific, and cultural ties of mutual benefit and enrichment. Nixon was proud that thanks to his diplomatic skills, he achieved an agreement that his predecessors were unable to reach. Nixon and Kissinger planned to link arms control to détente and to the resolution of other urgent problems through what Nixon called \"linkage.\" David Tal argues: This agreement paved the way for further discussion regarding international cooperation and a limitation of nuclear armaments, as seen through both the SALT II Treaty and the Washington Summit of 1973.", "section_level": 1}, {"title": "SALT II Treaty.", "content": "SALT II was a series of talks between United States and Soviet negotiators from 1972 to 1979 which sought to curtail the manufacture of strategic nuclear weapons. It was a continuation of the SALT I talks and was led by representatives from both countries. SALT II was the first nuclear arms treaty which assumed real reductions in strategic forces to 2,250 of all categories of delivery vehicles on both sides. The SALT II Treaty banned new missile programs (a new missile defined as one with any key parameter 5% better than in currently deployed missiles), so both sides were forced to limit their new strategic missile types development and construction, such as the development of additional fixed ICBM launchers. Likewise, this agreement would limit the number of MIRVed ballistic missiles and long range missiles to 1,320. However, the United States preserved their most essential programs like the Trident missile, along with the cruise missiles President Jimmy Carter wished to use as his main defensive weapon as they were too slow to have first strike capability. In return, the USSR could exclusively retain 308 of its so-called \"heavy ICBM\" launchers of the SS-18 type. A major breakthrough for this agreement occurred at the Vladivostok Summit meeting in November 1974, when President Gerald Ford and General Secretary Leonid Brezhnev came to an agreement on the basic framework for the SALT II agreement. The elements of this agreement were stated to be in effect through 1985. An agreement to limit strategic launchers was reached in Vienna on June 18, 1979, and was signed by Leonid Brezhnev and Carter at a ceremony held in the Redoutensaal of the imperial Hofburg Palace. Six months after the signing, the Soviet Union invaded Afghanistan, and in September of the same year, the United States discovered that a Soviet combat brigade was stationed in Cuba. Although President Carter claimed this Soviet brigade had only recently been deployed to Cuba, the unit had been stationed on the island since the Cuban Missile Crisis of 1962. In light of these developments, President Carter withdrew the treaty from consideration in January 1980 so that it was never ratified by the U.S. Senate.

Unusually, he spent his entire academic life in the faculty of arts, rather than obtaining the doctorate in law, medicine or theology that typically prepared the way for a career in philosophy. Also unusual for a philosopher of his time, Buridan further maintained his intellectual independence by remaining a secular cleric, rather than joining a religious order. A papal letter of 1330 refers to him as simply, \"\"clericus Atrebatensis diocoesis, magister in artibus\" [a cleric from the Diocese of Arras and Master of Arts].\" As university statutes only permitted those educated in theology to teach or write on the subject, there are no writings from Buridan on either theological matters or commentary of Peter Lombard's \"Sentences\". Speculation on his reasons for avoiding religious matters have remained uncertain. Most scholars think it is unlikely that he went unnoticed, given his philosophical talents. As well, it is unlikely that he could not afford to study theology, given that he received several bursaries and stipends. Indeed, he is listed in a document from 1350 as being among the teachers capable of supporting themselves without the need for financial assistance from the University. Zupko has speculated that Buridan \"deliberately chose to remain among the \"'artists\" [artistae],'\" possibly envisioning philosophy as a secular enterprise based on what is evident to both the senses and the intellect, rather than the non-evident truths of theology revealed through scripture and doctrine. The last appearance of Buridan in historical documents came in 1359, where he was mentioned as the adjudicator in a territorial dispute between the English and Picard nations. It is supposed that he died sometime after then, since one of his benefices was awarded to another person in 1362.

Thus, in the Aristotelian view, a projectile moving through the air would owe its continuing motion to \"eddies\" or \"vibrations\" in the surrounding medium, a phenomenon known as \"antiperistasis\". In the absence of a proximate force, the body would come to rest almost immediately. The theory of impetus proposed that motion was maintained by some property of the body, imparted when it was set in motion. Buridan was the first to name this motion-maintaining property \"impetus\" but the theory itself probably did not originate with him. A less sophisticated notion of impressed forced can be found in the Avicenna's doctrine of \"mayl\" (inclination). In this he was possibly influenced by John Philoponus who was developing the Stoic notion of \"hormé\" (impulse). The major difference between Buridan's theory and that of his predecessor is that he rejected the view that the impetus dissipated spontaneously, instead asserting that a body would be arrested by the forces of air resistance and gravity which might be opposing its impetus. Buridan further held that the impetus of a body increased with the speed with which it was set in motion, and with its quantity of matter. This is closely related to the modern concept of momentum. Buridan saw impetus as \"causing\" the motion of the object: Buridan also contended that impetus is a variable quality whose force is determined by the speed and quantity of the matter in the subject.

His oldest brother, Christian, died in a boating accident in 1934, and his youngest, Harald, from childhood meningitis. Of the others, Hans became a physician; Erik, a chemical engineer; and Ernest, a lawyer and an Olympic athlete who played field hockey for Denmark at the 1948 Summer Olympics in London. The family lived at the Institute of Theoretical Physics at the University of Copenhagen, now known as the Niels Bohr Institute, where he grew up surrounded by physicists who were working with his father, such as Hans Kramers, Oskar Klein, Yoshio Nishina, Wolfgang Pauli and Werner Heisenberg. In 1932, the family moved to the Carlsberg Æresbolig, a mansion donated by Carl Jacobsen, the heir to Carlsberg breweries, to be used as an honorary residence by the Dane who had made the most prominent contribution to science, literature or the arts. Bohr went to high school at in Copenhagen. In 1940, shortly after the German occupation of Denmark in April, he entered the University of Copenhagen, where he studied physics. He assisted his father, helping draft correspondence and articles related to epistemology and physics. In September 1943, word reached his family that the Nazis considered them to be Jewish, because Aage's grandmother, Ellen Adler Bohr, had been Jewish, and that they therefore were in danger of being arrested. The Danish resistance helped the family escape by sea to Sweden. Bohr arrived there in October 1943, and then flew to Britain on a de Havilland Mosquito operated by British Overseas Airways Corporation. The Mosquitoes were unarmed high-speed bomber aircraft that had been converted to carry small, valuable cargoes or important passengers. By flying at high speed and high altitude, they could cross German-occupied Norway, and yet avoid German fighters. Bohr, equipped with parachute, flying suit and oxygen mask, spent the three-hour flight lying on a mattress in the aircraft's bomb bay. On arrival in London, Bohr rejoined his father, who had flown to Britain the week before. He officially became a junior researcher at the Department of Scientific and Industrial Research, but actually served as personal assistant and secretary to his father. The two worked on Tube Alloys, the British atomic bomb project. On 30 December 1943, they made the first of a number of visits to the United States, where his father was a consultant to the Manhattan Project. Due to his father's fame, they were given false names; Bohr became James Baker, and his father, Nicholas Baker. In 1945, the director of the Los Alamos Laboratory, Robert Oppenheimer, asked them to review the design of the modulated neutron initiator. They reported that it would work. That they had reached this conclusion put Enrico Fermi's concerns about the viability of the design to rest. The initiators performed flawlessly in the bombs used in the atomic bombings of Hiroshima and Nagasaki in August 1945.", "section_level": 1}, {"title": "Career.", "content": "In August 1945, with the war ended, Bohr returned to Denmark, where he resumed his university education, graduating with a master's degree in 1946, with a thesis concerned with some aspects of atomic stopping power problems. In early 1948, Bohr became a member of the Institute for Advanced Study in Princeton, New Jersey. While paying a visit to Columbia University, he met Isidor Isaac Rabi, who sparked in him an interest in recent discoveries related to the hyperfine structure of deuterium. This led to Bohr becoming a visiting fellow at Columbia from January 1949 to August 1950. While in the United States, Bohr married Marietta Soffer on 11 March 1950. They had three children: Vilhelm, Tomas and Margrethe. By the late 1940s it was known that the properties of atomic nuclei could not be explained by then-current models such as the liquid drop model developed by Niels Bohr amongst others. The shell model, developed in 1949 by Maria Goeppert-Mayer and others, allowed some additional features to be explained, in particular the so-called magic numbers. However, there were also properties that could not be explained, including the non-spherical distribution of charge in certain nuclei. In a 1950 paper, James Rainwater of Columbia University suggested a variant of the drop model of the nucleus that could explain a non-spherical charge distribution. Rainwater's model postulated a nucleus like a balloon with balls inside that distort the surface as they move about. He discussed the idea with Bohr, who was visiting Columbia at the time, and had independently conceived the same idea, and had, about a month after Rainwater's submission, submitted for publication a paper that discussed the same problem, but along more general lines. Bohr imagined a rotating, irregular-shaped nucleus with a form of surface tension. Bohr developed the idea further, in 1951 publishing a paper that comprehensively treated the relationship between oscillations of the surface of the nucleus and the movement of the individual nucleons. Upon his return to Copenhagen in 1950, Bohr began working with Ben Mottelson to compare the theoretical work with experimental data. In three papers, that were published in 1952 and 1953, Bohr and Mottelson demonstrated close agreement between theory and experiment; for example, showing that the energy levels of certain nuclei could be described by a rotation spectrum. They were thereby able to reconcile the shell model with Rainwater's concept. This work stimulated many new theoretical and experimental studies. Bohr, Mottelson and Rainwater were jointly awarded the 1975 Nobel Prize in Physics \"for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection\". Because his father had been awarded the prize in 1922, Bohr became one of only four pairs of fathers and sons to win the Nobel Prize in Physics. Only after doing his Nobel Prize-winning research did Bohr receive his doctorate from the University of Copenhagen, in 1954, writing his thesis on \"Rotational States of Atomic Nuclei\". Bohr became a professor at the University of Copenhagen in 1956, and, following his father's death in 1962, succeeded him as director of the Niels Bohr Institute, a position he held until 1970. He remained active there until he retired in 1992. He was also a member of the board of the Nordic Institute for Theoretical Physics (Nordita) from its inception in 1957, and was its director from 1975 to 1981. In addition to the Nobel Prize, he won the Dannie Heineman Prize for Mathematical Physics in 1960, the Atoms for Peace Award in 1969, H.C. Ørsted Medal in 1970, Rutherford Medal and Prize in 1972, John Price Wetherill Medal in 1974, and the Ole Rømer medal in 1976. Bohr and Mottelson continued to work together, publishing a two-volume monograph, \"Nuclear Structure\". The first volume, \"Single-Particle Motion,\" appeared in 1969; the second, \"Nuclear Deformations,\" in 1975. In 1972 he was awarded an honorary degree, doctor philos. honoris causa, at the Norwegian Institute of Technology, later part of Norwegian University of Science and Technology. In 1981, Bohr became a founding member of the World Cultural Council. His wife Marietta died on 2 October 1978. In 1981, he married Bente Scharff Meyer (1926–2011).

Records show that Waldseemüller was enrolled in 1490 at the University of Freiburg where Gregor Reisch, a noted humanist scholar, was one of his influential teachers. After finishing at the university, he lived in Basel where he was ordained a priest and, apparently, gained experience in printing and engraving while working with the printer community in Basel. Around 1500, an association of humanist scholars formed in Saint-Dié under the patronage of René II, Duke of Lorraine. They called themselves the \"Gymnasium Vosagense\" and their leader was Walter Lud. Their initial intention was to publish a new edition of Ptolemy's \"Geography\". Waldseemüller was invited to join the group and contribute his skills as a cartographer. It is not clear how he came to the groups's attention, but Lud later described him as a master cartographer.

The \"Gymnasium\" surmised that this was the \"new world\" or the \"antipodes\" hypothesized by classical writers. The Soderini Letter gave Vespucci credit for discovery of this new continent and implied that newly obtained Portuguese maps were based on his explorations. They decided to put aside the \"Geography\" for the moment and publish a brief \"Introduction to Cosmography\" with an accompanying world map. The \"Introduction\" was written by Ringmann and included a Latin translation of the \"Soderini Letter\". In a preface to the \"Letter\", Ringmann wrote \"I see no reason why anyone could properly disapprove of a name derived from that of Amerigo, the discoverer, a man of sagacious genius. A suitable form would be Amerige, meaning Land of Amerigo, or America, since Europe and Asia have received women's names.\" While Ringmann was writing the \"Introduction\", Waldseemüller focused on the creation of a world map using an aggregation of sources including maps based on the works of Ptolemy, Henricus Martellus, Alberto Cantino and Nicolò de Caverio. In addition to a large 12-panel wall map, Waldseemüller created a smaller, simplified globe. The wall map was decorated with prominent portraits of Ptolemy and Vespucci. The map and globe were notable for showing the New World as a continent separate from Asia and for naming the southern landmass America. By April 1507, the map, globe and accompanying book, \"Introduction to Cosmography\", were published. A thousand copies were printed and sold throughout Europe. The \"Introduction\" and map were a great success and four editions were printed in the first year alone. The map was widely used in universities and was influential among cartographers who admired the craftsmanship that went into its creation. In the following years other maps were printed that often incorporated the name America. Although Waldseemüller had intended the name to apply only to a specific part of Brazil, other maps applied it to the entire continent.

With this key reference they continued to make progress and Waldseemüller was able to finish his maps. However, completion was forestalled when their patron, Duke René II, died in 1508. The new edition was finally printed in 1513 by Johannes Schott in Strasbourg. By then, Waldseemüller had pulled out of the project and was not credited for his cartographic work. Nevertheless his maps were recognized as important contributions to the science of cartography and was considered a standard reference work for many decades. Approximately twenty of Waldseemüller's \"tabulae modernae\" (modern maps) were included in the new \"Geography\" as a separate appendix, \"Claudii Ptolemaei Supplementem\". This supplement constitutes the first modern atlas. Maps of Lorraine and the upper Rhine region were the first printed maps of those regions and were probably based on survey work done by Waldseemüller himself. The world map published in the 1513 \"Geography\" seems to indicate that Waldseemüller had second thoughts about the name and the nature of the lands discovered in the western Atlantic. The New World was no longer clearly shown as a continent separate from Asia and the name America had been replaced with \"Terra Incognita\" (Unknown Land).

Everything is subject to the concept of primitive cohesion.

Most compounds that contain one or more asymmetric carbon (or other element with a tetrahedral geometry) atoms show enantiomerism, but this is not always true. Compounds that contain two or more asymmetric carbon atoms but have a plane of symmetry with respect to the whole molecule are known as \"meso\" compounds. A \"meso\" compound does not have a mirror image stereoisomer because it is its own mirror image (i.e., it and its mirror image are the same molecule). For instance, \"meso\" tartaric acid (shown on the right) has two asymmetric carbon atoms, but it does not exhibit enantiomerism because each of the two halves of the molecule is equal and opposite to the other and thus is superposable on its geometric mirror image. Conversely, there exist forms of chirality that do not require individual asymmetric atoms. In fact, there are four distinct types of chirality: central, axial, planar, and helical chirality. Having an enantiomer by virtue of an asymmetric carbon atom represents the most common type of central chirality. The other three types of chirality do not involve asymmetric carbon atoms, and even central chirality does not require the center of chirality to be located at a carbon or any other atom. Consequently, while the presence of an asymmetric carbon atom is a convenient characteristic to look for when determining whether a molecule will have an enantiomer, it is neither sufficient nor necessary as a criterion. As a rigorous criterion, a molecule is chiral, and will therefore possess an enantiomer, if and only if it belongs to one of the chiral point groups: \"C\", \"D\", \"T\", \"O\", and \"I\". However, as a caveat, enantiomers are not necessarily isolable if there is an accessible pathway for racemization at a given temperature and timescale. For example, amines with three distinct substituents are chiral, but with the exception of only a few atypical cases (e.g. substituted \"N\"-chloroaziridines), they rapidly planarize and invert (\"umbrella inversion\") at room temperature, leading to racemization. If the racemization is fast enough, the molecule can often be treated as an achiral, averaged structure.", "section_level": 1}, {"title": "Examples.", "content": "An example of such an enantiomer is the sedative thalidomide, which was sold in a number of countries around the world from 1957 until 1961.

A less common method is by enantiomer self-disproportionation. The second strategy is asymmetric synthesis: the use of various techniques to prepare the desired compound in high enantiomeric excess. Techniques encompassed include the use of chiral starting materials (chiral pool synthesis), the use of chiral auxiliaries and chiral catalysts, and the application of asymmetric induction. The use of enzymes (biocatalysis) may also produce the desired compound. Enantioconvergent synthesis is the synthesis of one enantiomer from a racemic precursor molecule utilizing both enantiomers.

In functional linguistics, a sentence is typically associated with a clause and a clause can be either a \"clause simplex\" or a \"clause complex\". A clause is a clause simplex if it represents a single process going on through time and it is a clause complex if it represents a logical relation between two or more processes and is thus composed of two or more clause simplexes. A clause (simplex) typically contains a predication structure with a subject noun phrase and a finite verb. Although the subject is usually a noun phrase, other kinds of phrases (such as gerund phrases) work as well, and some languages allow subjects to be omitted. In the examples below, the subject of the outmost clause simplex is in italics and the subject of \"boiling\" is in square brackets. Notice that there is clause embedding in the second and third examples. There are two types of clauses: \"independent\" and \"non-independent\"/\"interdependent\". An independent clause realises a speech act such as a statement, a question, a command or an offer. A non-independent clause does not realise any act. A non-independent clause (simplex or complex) is usually logically related to other non-independent clauses. Together they usually constitute a single independent clause (complex). For that reason, non-independent clauses are also called \"interdependent\". For instance, the non-independent clause \"because I have no friends\" is related to the non-independent clause \"I don't go out\" in \"I don't go out, because I have no friends\". The whole clause complex is independent because it realises a statement. What is stated is the causal nexus between having no friend and not going out. When such a statement is acted out, the fact that the speaker doesn't go out is already established, therefore it cannot be stated. What is still open and under negotiation is the reason for that fact. The causal nexus is represented by the independent clause complex and not by the two interdependent clause simplexes.

Besides Russian, the Kapitsa family also spoke Romanian. Kapitsa's studies were interrupted by the First World War, in which he served as an ambulance driver for two years on the Polish front. He graduated from the Petrograd Polytechnical Institute in 1918. His wife and two children died in the flu epidemic of 1918-19. He subsequently studied in Britain, working for over ten years with Ernest Rutherford in the Cavendish Laboratory at the University of Cambridge, and founding the influential Kapitza club. He was the first director (1930–34) of the Mond Laboratory in Cambridge. In the 1920s he originated techniques for creating ultrastrong magnetic fields by injecting high current for brief periods into specially constructed air-core electromagnets. In 1928 he discovered the linear dependence of resistivity on magnetic field strength in various metals for very strong magnetic fields. In 1934 Kapitsa returned to Russia to visit his parents but the Soviet Union prevented him from travelling back to Great Britain. As his equipment for high-magnetic field research remained in Cambridge (although later Ernest Rutherford negotiated with the British government the possibility of shipping it to the USSR), he changed the direction of his research to the study of low temperature phenomena, beginning with a critical analysis of the existing methods for achieving low temperatures. In 1934 he developed new and original apparatus (based on the adiabatic principle) for making significant quantities of liquid helium. Kapitsa formed the Institute for Physical Problems, in part using equipment which the Soviet government bought from the Mond Laboratory in Cambridge (with the assistance of Rutherford, once it was clear that Kapitsa would not be permitted to return). In Russia, Kapitsa began a series of experiments to study liquid helium, leading to the discovery in 1937 of its superfluidity (not to be confused with superconductivity). He reported the properties of this new state of matter in a series of papers, for which he was later awarded the Nobel Prize in Physics \"for basic inventions and discoveries in the area of low-temperature physics\". In 1939 he developed a new method for liquefaction of air with a low-pressure cycle using a special high-efficiency expansion turbine. Consequently, during World War II he was assigned to head the Department of Oxygen Industry attached to the USSR Council of Ministers, where he developed his low-pressure expansion techniques for industrial purposes. He invented high power microwave generators (1950–1955) and discovered a new kind of continuous high pressure plasma discharge with electron temperatures over 1,000,000 K. In November 1945, Kapitsa quarreled with Lavrentiy Beria, head of the NKVD and in charge of the Soviet atomic bomb project, writing to Joseph Stalin about Beria's ignorance of physics and his arrogance.

He decided to study chemistry and began first at the laboratory of Edmond Frémy and later at that of Pierre Paul Dehérain. Dehérain persuaded him to pursue an academic career. He passed the baccalauréat, which was necessary to study at university, in 1874 after an earlier failed attempt. During his time in Paris he became a friend of the chemist Alexandre Léon Étard and the botanist Vasque. He published his first scientific paper, about carbon dioxide and oxygen metabolism in plants, with Dehérain in 1874. He left plant physiology and then turned towards inorganic chemistry; subsequently his research on pyrophoric iron was well received by the two most prominent French inorganic chemists of that time, Henri Etienne Sainte-Claire Deville and Jules Henri Debray. After Moissan received his Ph.D. on cyanogen and its reactions to form cyanures in 1880, his friend Landrine offered him a position at an analytic laboratory. His marriage, to Léonie Lugan, took place in 1882. They had a son in 1885. During the 1880s, Moissan focused on fluorine chemistry and especially the production of fluorine itself. He had no laboratory of his own, but used several laboratories, for example that of Charles Friedel. There he had access to a strong battery consisting of 90 Bunsen cells which made it possible to observe a gas produced by the electrolysis of molten arsenic trichloride; the gas was reabsorbed by the arsenic trichloride. The electrolysis of hydrogen fluoride yielded fluorine on 26 June 1886. The French academy of science sent three representatives, Marcellin Berthelot, Henri Debray, and Edmond Frémy, to verify the results, but Moissan was unable to reproduce them, owing to the absence from the hydrogen fluoride of traces of potassium fluoride present in the previous experiments. After resolving the problem and demonstrating the production of fluorine several times, he was awarded a prize of 10,000 francs. In subsequent years, until 1891, he focused on the study of fluorine chemistry. He discovered numerous fluorine compounds, such as (together with Paul Lebeau) SF in 1901.

The mixture was needed because hydrogen fluoride is a nonconductor. The device was built with platinum/iridium electrodes in a platinum holder and the apparatus was cooled to −50 °C. The result was the complete isolation of the hydrogen produced at the negative electrode from the fluorine produced at the positive one. This is essentially still the way fluorine is produced today.

Thus, in order for us to continue to believe in the essential propriety and rightness of the universe (what the narrator calls \"the categorical agreement with being\"), we live in a world \"in which shit is denied and everyone acts as though it did not exist\". For Kundera's narrator, this is the definition of kitsch: an \"aesthetic ideal\" which \"excludes everything from its purview which is essentially unacceptable in human existence\". The novel goes on to relate this definition of kitsch to politics, and specifically — given the novel's setting in Prague around the time of the 1968 invasion by the Soviet Union — to communism and totalitarianism. He gives the example of the Communist May Day ceremony, and of the sight of children running on the grass and the feeling this is supposed to provoke. This emphasis on feeling is fundamental to how kitsch operates: Kitsch causes two tears to flow in quick succession. The first tear says: How nice to see children running on the grass! The second tear says: How nice to be moved, together with all mankind, by children running on the grass! It is the second tear that makes kitsch kitsch. According to the narrator, kitsch is \"the aesthetic ideal of all politicians and all political parties and movements\"; however, where a society is dominated by a single political movement, the result is \"totalitarian kitsch\": When I say \"totalitarian,\" what I mean is that everything that infringes on kitsch must be banished for life: every display of individualism (because a deviation from the collective is a spit in the eye of the smiling brotherhood); every doubt (because anyone who starts doubting details will end by doubting life itself); all irony (because in the realm of kitsch everything must be taken quite seriously). Kundera's concept of \"totalitarian kitsch\" has since been invoked in the study of the art and culture of regimes such as Stalin's Soviet Union, Nazi Germany, Fascist Italy and Iraq under Saddam Hussein.

He and Rutherford realized that the anomalous behaviour of radioactive elements was because they decayed into other elements. This decay also produced alpha, beta, and gamma radiation. When radioactivity was first discovered, no one was sure what the cause was. It needed careful work by Soddy and Rutherford to prove that atomic transmutation was in fact occurring. In 1903, with Sir William Ramsay at University College London, Soddy showed that the decay of radium produced helium gas. In the experiment a sample of radium was enclosed in a thin-walled glass envelope sited within an evacuated glass bulb. After leaving the experiment running for a long period of time, a spectral analysis of the contents of the former evacuated space revealed the presence of helium. Later in 1907, Rutherford and Thomas Royds showed that the helium was first formed as positively charged nuclei of helium (He) which were identical to alpha particles, which could pass through the thin glass wall but were contained within the surrounding glass envelope. From 1904 to 1914, Soddy was a lecturer at the University of Glasgow. Ruth Pirret worked as his research assistant during this time. In May 1910 Soddy was elected a Fellow of the Royal Society. In 1914 he was appointed to a chair at the University of Aberdeen, where he worked on research related to World War I. The work that Soddy and his research assistant Ada Hitchins did at Glasgow and Aberdeen showed that uranium decays to radium. It also showed that a radioactive element may have more than one atomic mass though the chemical properties are identical. Soddy named this concept isotope meaning \"same place\". The word was initially suggested to him by Margaret Todd. Later, J. J. Thomson showed that non-radioactive elements can also have multiple isotopes. In 1913, Soddy also showed that an atom moves lower in atomic number by two places on alpha emission, higher by one place on beta emission. This was discovered at about the same time by Kazimierz Fajans, and is known as the radioactive displacement law of Fajans and Soddy, a fundamental step toward understanding the relationships among families of radioactive elements. Soddy published \"The Interpretation of Radium\" (1909) and \"Atomic Transmutation\" (1953). In 1918 he announced discovery of a stable isotope of Protactinium, working with John Arnold Cranston. This slightly post-dated its discovery by German counterparts; however, it is said their discovery was actually made in 1915 but its announcement was delayed due to Cranston's notes being locked away whilst on active service in the First World War. In 1919 he moved to the University of Oxford as Dr Lee's Professor of Chemistry, where, in the period up till 1936, he reorganized the laboratories and the syllabus in chemistry. He received the 1921 Nobel Prize in chemistry for his research in radioactive decay and particularly for his formulation of the theory of isotopes. His work and essays popularising the new understanding of radioactivity was the main inspiration for H. G. Wells's \"The World Set Free\" (1914), which features atomic bombs dropped from biplanes in a war set many years in the future. Wells's novel is also known as \"The Last War\" and imagines a peaceful world emerging from the chaos. In \"Wealth, Virtual Wealth and Debt\" Soddy praises Wells’s \"The World Set Free\".

While most of his proposals – \"to abandon the gold standard, let international exchange rates float, use federal surpluses and deficits as macroeconomic policy tools that could counter cyclical trends, and establish bureaus of economic statistics (including a consumer price index) in order to facilitate this effort\" – are now conventional practice, his critique of fractional-reserve banking still \"remains outside the bounds of conventional wisdom\" although a recent paper by the IMF reinvigorated his proposals.

Later in life he published a pamphlet \"Abolish Private Money, or Drown in Debt\" (1939) with a noted publisher of anti-Semitic texts.

Hevesy determined to look for that element on the basis of Bohr's atomic model. The mineralogical museum of Norway and Greenland in Copenhagen furnished the material for the research. Characteristic X-ray spectra recordings made of the sample indicated that a new element was present. The accepted account has been disputed by Mansel Davies and Eric Scerri who attribute the prediction that element 72 would be a transition element to the chemist Charles Bury. Supported financially by the Rockefeller Foundation, Hevesy had a very productive year. He developed the X-ray fluorescence analytical method, and discovered the samarium alpha-ray. It was here he began the use of radioactive isotopes in studying the metabolic processes of plants and animals, by tracing chemicals in the body by replacing part of stable isotopes with small quantities of the radioactive isotopes. In 1923, Hevesy published the first study on the use of the naturally radioactive Pb as radioactive tracer to follow the absorption and translocation in the roots, stems and leaves of Vicia faba, also known as the broad bean. Later, in 1943, the work on radioactive tracing would earn Hevesy the Nobel Prize in Chemistry. In 1924 Hevesy returned to Freiburg as Professor of Physical Chemistry, and in 1930 went to Cornell University, Ithaca as Baker Lecturer. Four years later he resumed his activities at Niels Bohr's Institute, based there through 1952.

The preparation work on the two ships, the 985-ton sloop-of-war \"Vostok\" (\"East\") and the 530-ton support vessel \"Mirny\" (\"Peaceful\") was carried out by Mikhail Lazarev, who had captained his own circumnavigation of the globe before. Bellingshausen became the captain of \"Vostok\", and Lazarev captained \"Mirny\". The journey started from Kronstadt on 4 June 1819. They stopped briefly in England, where Bellingshausen met with Sir Joseph Banks, the president of the Royal Society. Banks had sailed with Captain James Cook fifty years earlier and supplied the Russians with books and charts for their expedition. Leaving Portsmouth on 5 September 1819 the expedition crossed the Antarctic Circle (the first to do so since Cook) on 26 January 1820 (New Style). On 27 January the expedition discovered the Antarctic mainland approaching the Antarctic coast at a point with coordinates 69o21'28\"S 2o14'50\"W and seeing ice-fields there. The point in question lies within twenty miles of the Antarctic mainland. Bellingshausen's diary, his report to the Russian Naval Minister on 21 July 1821 and other documents, available in the Russian State Museum of the Arctic and Antarctic in Saint Petersburg, Russia, were carefully compared with the log-books of other claimants by the British polar historian A. G. E. Jones in his 1982 study \"Antarctica Observed\". Jones concluded that Bellingshausen, rather than the Royal Navy's Edward Bransfield on 30 January 1820 or the American Nathaniel Palmer on 17 November 1820, was indeed the discoverer of the sought-after Terra Australis. During the voyage Bellingshausen also visited Ship Cove in New Zealand, the South Shetland Islands, and discovered and named Peter I, Zavodovski, Leskov and Visokoi Islands, and a peninsula of the Antarctic mainland that he named the Alexander Coast but that has more recently borne the designation of Alexander Island.

The theory posits that we use two primary cues for sound lateralisation, using the difference in the phases of sinusoidal components of the sound and the difference in amplitude (level) between the two ears. During the First World War, he was president of the government's \"Advisory Committee for Aeronautics\", which was located at the National Physical Laboratory, and chaired by Richard Glazebrook. In 1919, Rayleigh served as President of the Society for Psychical Research. As an advocate that simplicity and theory be part of the scientific method, Rayleigh argued for the principle of similitude. Rayleigh was elected Fellow of the Royal Society on 12 June 1873, and served as president of the Royal Society from 1905 to 1908. From time to time Rayleigh participated in the House of Lords; however, he spoke up only if politics attempted to become involved in science. He died on 30 June 1919, at his home in Witham, Essex.

After an element is inserted into or deleted from a heap, the heap property may be violated and the heap must be balanced by swapping elements within the array. In an implicit heap data structure, the first (or last) element will contain the root. The next two elements of the array contain its children. The next four contain the four children of the two child nodes, etc. Thus the children of the node at position \"n\" would be at positions 2n and 2n + 1 in a one-based array, or 2n + 1 and 2n + 2 in a zero-based array. Computing the index of the parent node of n-th element is also straightforward. For one-based arrays the parent of element n is located at position n/2. Similarly, for zero-based arrays, is the parent is located at position (n-1)/2 (floored). This allows moving up or down the tree by doing simple index computations. Balancing a heap is done by sift-up or sift-down operations (swapping elements which are out of order). As we can build a heap from an array without requiring extra memory (for the nodes, for example), heapsort can be used to sort an array in-place. Different types of heaps implement the operations in different ways, but notably, insertion is often done by adding the new element at the end of the heap in the first available free space. This will generally violate the heap property, and so the elements are then shifted up until the heap property has been reestablished. Similarly, deleting the root is done by removing the root and then putting the last element in the root and sifting down to rebalance. Thus replacing is done by deleting the root and putting the \"new\" element in the root and sifting down, avoiding a sifting up step compared to pop (sift down of last element) followed by push (sift up of new element). Construction of a binary (or \"d\"-ary) heap out of a given array of elements may be performed in linear time using the classic Floyd algorithm, with the worst-case number of comparisons equal to 2\"N\" − 2\"s\"(\"N\") − \"e\"(\"N\") (for a binary heap), where \"s\"(\"N\") is the sum of all digits of the binary representation of \"N\" and \"e\"(\"N\") is the exponent of 2 in the prime factorization of \"N\".

He did not want to use the name Schwarz-Markt (\"Schwarzmarkt\" means \"black market\") and rather use the name of Josef Schwarz's former business partner, A. Lidl, but legal reasons prevented him from taking over the name for his discount stores. When he discovered a newspaper article about the painter and retired schoolteacher Ludwig Lidl, he bought the rights to the name from him for 1,000 German marks. Lidl is part of the Schwarz Group, the fifth-largest retailer in the world with sales of €104.3 billion (2018). The first Lidl discount store was opened in 1973, copying the Aldi concept. Schwarz rigorously removed merchandise that did not sell from the shelves, and cut costs by keeping the size of the retail outlets as small as possible. By 1977, the Lidl chain comprised 33 discount stores. Lidl opened its first UK store in 1994. Since then, Lidl UK has grown consistently, and today has over 800 stores. While it is still a small player in the United Kingdom, with a grocery market share of less than 5%, its importance, along with that of continental, no-frills competitor Aldi is growing, with half of the shoppers in the United Kingdom visiting Aldi or Lidl over Christmas 2014. Sven Seidel was appointed CEO of the company in March 2014, after the previous CEO Karl-Heinz Holland stepped down. Holland had served as chief executive since 2008 but left due to undisclosed \"unbridgeable\" differences over future strategy. Seidel stepped down from his position in February 2017 after \"Manager Magazin\" reported he had fallen out of favour with Klaus Gehrig, who has headed the Schwarz Group since 2004.

In Andalusia the golf courses became part of their habitat. Eurasian otters may also live along the coast, in salt water, but require regular access to fresh water to clean their fur.

An individual's territory may vary between about long, with about being usual. The length of the territory depends on the density of food available and the width of the water suitable for hunting (it is shorter on coasts, where the available width is much wider, and longer on narrower rivers).The Eurasian otter uses its feces, spraints, to mark its territory and prioritize the use of resources to other group members. The territories are only held against members of the same sex, so those of males and females may overlap. Mating takes place in water. Eurasian otters are nonseasonal breeders (males and females will breed at any time of the year) and it has been found that their mating season is most likely determined simply by the otters' reproductive maturity and physiological state. Female otters become sexually mature between 18 and 24 months old and the average age of first breeding is found to be years. Gestation for the Eurasian otter is 60–64 days, the litter weighing about 10% of the female body mass. After the gestation period, one to four pups are born, which remain dependent on the mother for about 13 months. The male plays no direct role in parental care, although the territory of a female with her pups is usually entirely within that of the male. Hunting mainly takes place at night, while the day is usually spent in the Eurasian otter's holt (den) – usually a burrow or hollow tree on the riverbank which can sometimes only be entered from underwater.

In the United Kingdom, the number of sites with an otter presence increased by 55% between 1994 and 2002. In August, 2011, the Environment Agency announced that otters had returned to every county in England since vanishing from every county except the West Country and parts of Northern England. Recovery is partly due to a ban on the most harmful pesticides that has been in place across Europe since 1979, partly to improvements in water quality leading to increases in prey populations, and partly to direct legal protection under the European Union Habitats Directive and national legislation in several European countries. In Hong Kong, it is a protected species under Wild Animals Protection Ordinance Cap 170. It is listed as Near Threatened by the IUCN Red List. In Asia, it is listed as endangered in Pakistan, India, Bangladesh, Myanmar and Thailand, and critically endangered in Mongolia. Most species that are victims of population decline or a loss of habitat tend to eventually lose their genetic difference due to inbreeding from small populations. A study conducted in 2001, examined whether or not the populations of Eurasian otters suffered from a lack of genetic variability. In the study, they examined teeth of otter skulls at the Zoological Museum, Copenhagen and the Natural History Museum, Aarhus. The samples were collected between 1883 and 1963 in Denmark (Funen, Zealand, and Jutland). The study examined the tissue on the teeth of the skulls and determined the genetic variability based on DNA analysis. In conclusion, the study discovered that despite the population declines, the Eurasian otter was not a victim of declining genetic variability.

Later, the Celtic tribe of the Helvetii inhabited the area. Caesar's troops defeated the Helvetii in 58 BC and as a consequence the Romans settled in the area. The many towns established by the Romans include Vevey () and Lausanne (\"Lausonium\" or \"Lausonna\"). In 27 BC the state of \"Civitas Helvetiorum\" was established around the capital of Avenches (\"Aventicum\"). There are still many Roman remains around the town today. Between the 2nd and the 4th centuries Alemannic tribes repeatedly invaded the area, and in the 5th century the Burgundians occupied the territory. The Merovingian Franks later replaced the Burgundians. Their control did not last long either, and in 888 the area of the canton of Vaud became part of the Carolingian Empire (the successor state to the Merovingians). In 1032 the Zähringens of Germany defeated the Burgundians. The Zähringens themselves were succeeded in 1218 by the counts of Savoy. It was only under the counts of Savoy that the area gained political unity as the Barony of Vaud. A part stretching from Attalens to the River Sarine, in the north, was absorbed by the canton of Fribourg. As the power of the House of Savoy declined at the beginning of the 15th century, troops from Bern occupied the land. By 1536 Bern had completely annexed the area. Vaud's Protestant Reformation started with co-workers of John Calvin like Pierre Viret (a famous debate took place at the cathedral of Lausanne), but it was only decisively implemented when Bern put its full force behind it. The Bernese occupiers were not popular amongst the population. In 1723 Major Abraham Davel led a revolt against Bern, in protest at what he saw as the denial of political rights of the French-speaking Vaudois by the German-speaking Bernese; he was subsequently beheaded. Later, inspired by the French Revolution of 1789–1799, the Vaudois drove out the Bernese governor in 1798 and declared the Lemanic Republic. Vaud nationalists like Frédéric-César de La Harpe had called for French intervention in liberating the area, and French Revolutionary troops moved in, taking over the whole of Switzerland itself in the process and setting up the Helvetic Republic. Under Napoleon I (Emperor 1804-1815), Vaud became (1798-1803) the canton of Léman. Unrest about the abolition of feudal rights and taxes led to increased discontent, which culminated in the revolt of the Bourla-papey in spring 1802, closely followed by the Stecklikrieg (August to October, 1802) that brought the end of the entire Helvetic Republic in 1803. In 1803 Vaud joined the re-installed Swiss Confederation. In spite of Bernese attempts to reclaim Vaud, it has remained a sovereign canton ever since. In the 19th century, the canton of Vaud was an outspoken opponent of the \"Sonderbund\" Catholic separatist movement, which led to intervention by 99,000 Swiss Federal troops under General Henri Dufour against 79,000 separatists, in the Sonderbund War (November 1847).

Thus, only few gravity yards were ever built, sometimes requiring massive earthwork (one example is the first German gravity yard at Dresden). Most gravity yards were built in Germany and Great Britain, a few also in some other European countries, for example Łazy yard near Zawiercie on the Warsaw-Vienna Railway (in Poland).

They work similarly to gravity yards, but the falling gradient is limited to a small part of the yard, namely the hump. It is the heart of the yard—a lead track on a small hill over which an engine pushes the cars. Single cars, or a block of coupled cars, are uncoupled just before or at the crest of the hump, and roll by gravity onto their destination tracks in the tracks where the cars are sorted, called the \"classification bowl\". The speed of the cars rolling down from the hump into the classification bowl must be regulated according to whether they are full or empty, heavy or light freight, varying number of axles, whether there are few or many cars on the classification tracks, and varying weather conditions, including temperature, wind speed and direction. As concerns speed regulation, there are two types of hump yards—without or with mechanisation by retarders. In the old non-retarder yards braking was usually done in Europe by railroaders who laid skates onto the tracks. The skate or wheel chock was manually (or, in rare cases, mechanically) placed on one or both of the rails so that the treadles or rims of the wheel or wheels caused frictional retardation and resulted in the halting of the railway car. In the United States this braking was done by riders on the cars. In the modern retarder yards this work is done by mechanized \"rail brakes\" called retarders, which brake the cars by gripping the wheels. They are operated either pneumatically or hydraulically. Pneumatic systems are prevalent in the United States, France, Belgium, Russia and China, while hydraulic systems are used in Germany, Italy and the Netherlands. Classification bowls in Europe typically consist of 20 to 40 tracks, divided into several fans or balloons of tracks, usually with eight classification tracks following a retarder in each one, often 32 tracks altogether. In the United States, many classification bowls have more than 40 tracks, which are often divided into six to ten classification tracks in each balloon loop. Bailey Yard in North Platte, Nebraska, United States, the world's largest classification yard, is a hump yard. Other large American hump yards include Argentine Yard in Kansas City, Kansas, Robert Young Yard in Elkhart, Indiana, Clearing Yard in Chicago, Illinois, Englewood Yard in Houston, Texas, and Waycross Rice Yard in Waycross, Georgia. Notably, in Europe, Russia and China, all major classification yards are hump yards. Europe's largest hump yard is that of Maschen near Hamburg, Germany; it is only slightly smaller than Bailey Yard. The second largest is in the port of Antwerp, Belgium. Most hump yards are single yards with one classification bowl, but some, mostly very large, hump yards have two of them, one for each direction, thus are double yards, such as the Maschen, Antwerp, Clearing, and Bailey yards. According to the PRRT&HS PRR Chronology, the first hump yard in the United States was opened May 11, 1903 as part of the Altoona Yards at Bells Mills (East Altoona). Other sources report the PRR yard at Youngwood, PA which opened in the 1880s to serve the Connellsville coke fields as the first U.S. hump yard.

In Germanic languages, including English, it was and still is called the \"Oder\", written in medieval Latin documents as \"Odera\" or \"Oddera\". Most notably, it was mentioned in the Dagome iudex, which described territory of the Duchy of Poland under Duke Mieszko I in A.D. 990, as a part of duchy's western frontier. Before Slavs settled along its banks, the Oder was an important trade route and towns in Germania were documented along with many tribes living between the rivers Albis (Elbe), Oder, and Vistula. Centuries later, after Germanic tribes, the Bavarian Geographer (ca. 845) specified the following West Slavic peoples: Sleenzane, Dadosesani, Opolanie, Lupiglaa, and Golensizi in Silesia and Wolinians with Pyrzycans in Western Pomerania. A document of the Bishopric of Prague (1086) mentions Zlasane, Trebovyane, Poborane, and Dedositze in Silesia. From the 13th century on, the Oder valley was central to German Ostsiedlung, making the towns on its banks German-speaking over the following centuries. The Finow Canal, first built in 1605, connects the Oder and Havel. After completion of the more straight Oder–Havel Canal in 1914, its economic relevance decreased. The earliest important undertaking with a view to improving the waterway was initiated by Frederick the Great, who recommended diverting the river into a new and straight channel in the swampy tract known as Oderbruch near Küstrin. The work was carried out in the years 1746–53, a large tract of marshland being brought under cultivation, a considerable detour cut off and the main stream successfully confined to a canal. In the late 19th century, three additional alterations were made to the waterway: By the Treaty of Versailles, navigation on the Oder became subject to International Commission of the Oder. Following the articles 363 and 364 of the Treaty Czechoslovakia was entitled to lease in Stettin (now Szczecin) its own section in the harbour, then called \"Tschechoslowakische Zone im Hafen Stettin\". The contract of lease between Czechoslovakia and Germany, and supervised by the United Kingdom, was signed on February 16, 1929, and would end in 2028, however, after 1945 Czechoslovakia did not regain this legal position, de facto abolished in 1938–39. At the 1943 Tehran Conference the allies decided that the new eastern border of Germany would run along the Oder. However, after World War II, the German areas east of the Oder and the Lusatian Neisse were put under Polish administration by the victorious allies at the Potsdam Conference (at the insistence of the Soviets). As a result, the so-called Oder–Neisse line formed the border between the Soviet occupation zone (from 1949 East Germany) and the areas of Germany under Polish administration. The final border between Germany and Poland was to be determined at a future peace conference. A part of the German population east of these two rivers was evacuated by the Nazis during the war or fled from the approaching Red Army. After the war, the remaining 8 million Germans were forcibly expelled from these territories by the Polish and Soviet administrations. East Germany confirmed the border with Poland under Soviet pressure in the Treaty of Zgorzelec in 1950. West Germany, after a period of refusal, confirmed the inviolability of the border in 1970 in the Treaty of Warsaw.

The most noticeable feature, however, is its huge bill, which measures from in length, which is yellow-orange, tending to deeper reddish-orange on its lower sections and culmen, and with a black base and large spot on the tip. It looks heavy, but as in other toucans it is relatively light because the inside largely is hollow. The tongue is nearly as long as the bill and very flat. This species is the largest toucan and the largest representative of the order Piciformes. The total length of the species is. Body weight in these birds can vary from, with males averaging against the smaller female, which averages. Among standard measurements, the wing chord is, the tail is and the tarsus is. Other than the size difference, there are no external differences between the sexes. Juveniles are duller and shorter-billed than adults. Its voice consists of a deep, coarse croaking, often repeated every few seconds. It also has a rattling call and will bill-clack. The bill is the largest relative to body size of all birds providing 30 to 50% of its body surface area, although another Neotropical species, the sword-billed hummingbird, has a longer bill relative to its body length. It was called by Buffon a “grossly monstrous” appendage. Diverse functions have been suggested. Charles Darwin suggested it was a sexual ornament: “toucans may owe the enormous size of their beaks to sexual selection, for the sake of displaying the diversified and vivid stripes of colour with which these organs are ornamented\". Further suggestions have included aid in peeling fruit, intimidating other birds when robbing their nests, social selection related to defense of territory, and as a visual warning. Research has shown that one function is as a surface area for heat exchange. The bill has the ability to modify blood flow and so regulate heat distribution in the bird, allowing it to use its bill as a thermal radiator. In terms of surface area used for this function, the bill relative to the bird's size is amongst the largest of any animal and has a network of superficial blood vessels supporting the thin horny sheath on the bill made of keratin called the rhamphotheca. In its capacity to remove body heat the bill is comparable to that of elephant ears. The ability to radiate heat depends upon air speed: if this is low only 25% of the adult bird's resting heat production to as much as four times this heat production. In comparison, the bill of a duck and the ears of elephant can shed only 9 to 9.1% of resting heat production. The bill normally is responsible for 30 to 60% of heat loss.

Preliminary work began the following year at Marshall Space Flight Center (MSFC) and the Smithsonian Astrophysical Observatory (SAO). In the meantime, in 1978, NASA launched the first imaging X-ray telescope, Einstein (HEAO-2), into orbit. Work continued on the AXAF project throughout the 1980s and 1990s. In 1992, to reduce costs, the spacecraft was redesigned. Four of the twelve planned mirrors were eliminated, as were two of the six scientific instruments. AXAF's planned orbit was changed to an elliptical one, reaching one third of the way to the Moon's at its farthest point. This eliminated the possibility of improvement or repair by the space shuttle but put the observatory above the Earth's radiation belts for most of its orbit. AXAF was assembled and tested by TRW (now Northrop Grumman Aerospace Systems) in Redondo Beach, California. AXAF was renamed Chandra as part of a contest held by NASA in 1998, which drew more than 6,000 submissions worldwide. The contest winners, Jatila van der Veen and Tyrel Johnson (then a high school teacher and high school student, respectively), suggested the name in honor of Nobel Prize–winning Indian-American astrophysicist Subrahmanyan Chandrasekhar. He is known for his work in determining the maximum mass of white dwarf stars, leading to greater understanding of high energy astronomical phenomena such as neutron stars and black holes. Fittingly, the name Chandra means \"moon\" in Sanskrit. Originally scheduled to be launched in December 1998, the spacecraft was delayed several months, eventually being launched in July 23, 1999, at 04:31 UTC by during STS-93. Chandra was deployed from \"Columbia\" at 11:47 UTC. The Inertial Upper Stage's first stage motor ignited at 12:48 UTC, and after burning for 125 seconds and separating, the second stage ignited at 12:51 UTC and burned for 117 seconds. At, it was the heaviest payload ever launched by the shuttle, a consequence of the two-stage Inertial Upper Stage booster rocket system needed to transport the spacecraft to its high orbit. Chandra has been returning data since the month after it launched. It is operated by the SAO at the Chandra X-ray Center in Cambridge, Massachusetts, with assistance from MIT and Northrop Grumman Space Technology. The ACIS CCDs suffered particle damage during early radiation belt passages. To prevent further damage, the instrument is now removed from the telescope's focal plane during passages. Although Chandra was initially given an expected lifetime of 5 years, on September 4, 2001, NASA extended its lifetime to 10 years \"based on the observatory's outstanding results.\" Physically Chandra could last much longer. A 2004 study performed at the Chandra X-ray Center indicated that the observatory could last at least 15 years. In July 2008, the International X-ray Observatory, a joint project between ESA, NASA and JAXA, was proposed as the next major X-ray observatory but was later cancelled. ESA later resurrected a downsized version of the project as the Advanced Telescope for High Energy Astrophysics (ATHENA), with a proposed launch in 2028.

X-ray photons would be absorbed by normal mirror surfaces, so mirrors with a low grazing angle are necessary to reflect them. Chandra uses four pairs of nested mirrors, together with their support structure, called the High Resolution Mirror Assembly (HRMA); the mirror substrate is 2 cm-thick glass, with the reflecting surface a 33 nm iridium coating, and the diameters are 65 cm, 87 cm, 99 cm and 123 cm. The thick substrate and particularly careful polishing allowed a very precise optical surface, which is responsible for Chandra's unmatched resolution: between 80% and 95% of the incoming X-ray energy is focused into a one-arcsecond circle. However, the thickness of the substrate limits the proportion of the aperture which is filled, leading to the low collecting area compared to XMM-Newton. Chandra's highly elliptical orbit allows it to observe continuously for up to 55 hours of its 65-hour orbital period. At its furthest orbital point from Earth, Chandra is one of the most distant Earth-orbiting satellites. This orbit takes it beyond the geostationary satellites and beyond the outer Van Allen belt. With an angular resolution of 0.5 arcsecond (2.4 μrad), Chandra possesses a resolution over 1000 times better than that of the first orbiting X-ray telescope.

To the assembled electors, this strange sight recalled the gospel scene of the descent of the Holy Spirit on Jesus at the time of his baptism by John the Baptist. The congregation took this as a sign that he was marked out for this dignity, and Fabian was at once proclaimed bishop by acclamation.", "section_level": 1}, {"title": "Papacy.", "content": "During Fabian's reign of 14 years, there was a lull in the storm of persecution which had resulted in the exile of both Anterus' predecessor Pontian and the antipope (and later saint) Hippolytus. Fabian had enough influence at court to effect the return of the bodies of both of these martyrs from Sardinia, where they had died at hard labor in the mines. The report that he baptized the emperor Philip the Arab and his son, however, is probably a legend, although he did seem to enjoy some connections at court, since the bodies of Pontian and Hippolytus could not have been exhumed without the emperor's approval. According to the sixth-century historian Gregory of Tours Fabian sent out the \"apostles to the Gauls\" to Christianise Gaul in A.D. 245. Fabian sent seven bishops from Rome to Gaul to preach the Gospel: Gatianus of Tours to Tours, Trophimus of Arles to Arles, Paul of Narbonne to Narbonne, Saturnin to Toulouse, Denis to Paris, Austromoine to Clermont, and Martial to Limoges. He also condemned Privatus, the originator of a new heresy in Africa. The \"Liber Pontificalis\" says that Fabian divided the Christian communities of Rome into seven districts, each supervised by a deacon. Eusebius (VI §43) adds that he appointed seven subdeacons to help collect the \"acta\" of the martyrs—the reports of the court proceedings on the occasion of their trials. There is also a tradition that he instituted the four minor clerical orders: porter, lector, exorcist, and acolyte. However most scholars believe these offices evolved gradually and were formally instituted at a later date. His deeds are thus described in the \"Liber Pontificalis\": \"Hic regiones dividit diaconibus et fecit vii subdiacones, qui vii notariis imminerent, Ut gestas martyrum integro fideliter colligerent, et multas fabricas per cymiteria fieri praecepit\". (\"He divided the \"regiones\" into deaconships and made seven sub-deaconships which seven secretaries oversaw, so that they brought together the deeds of the martyrs faithfully made whole, and he brought forth many works in the cemeteries.\") The \"Liberian Catalogue\" of the popes also reports that Fabian initiated considerable work on the catacombs, where honored Christians were buried, and where he also caused the body of Pope Pontian to be entombed at the catacomb of Callixtus. With the advent of Emperor Decius, the Roman government's tolerant policy toward Christianity temporarily ended. Decius ordered leading Christians to demonstrate their loyalty to Rome by offering incense to the cult images of deities which represented the Roman state. This was unacceptable to many Christians, who, while no longer holding most of the laws of the Old Testament to apply to them, took the commandment against idolatry with deadly seriousness. Fabian was thus one of the earliest victims of Decius, dying as a martyr on 20 January 250, at the beginning of the Decian persecution, probably in prison rather than by execution. Fabian was buried in the catacomb of Callixtus in Rome. The Greek inscription on his tomb has survived, and bears the words: His remains were later reinterred at San Sebastiano fuori le mura by Pope Clement XI where the Albani Chapel is dedicated in his honour.

The controversy arose in the context of a broad pastoral problem. During the Decian persecution some Christians had purchased certificates attesting that they had made the requisite sacrifices to the Roman gods. Others had denied they were Christians while yet others had in fact taken part in pagan sacrifices. These people were called \"lapsi\". The question arose that if they later repented, could they be readmitted to communion with the church, and if so, under what conditions.

Marred by financial and disciplinary disputes, the 1994 Cameroon squad was a shadow compared to the quarter-finals in 1990. Cameroon mustered just one point from three matches, and finished with a 6–1 defeat to Russia. However, Foé's performances (including a goal assist) prompted interest from European clubs. After turning down Auxerre for a trainee position, he signed for another French club, RC Lens of Ligue 1. His debut on 13 August 1994 was a 2–1 win against Montpellier. In five seasons at Lens, he won the 1998 French league title. In 1998, he was targeted by Manchester United, but Lens refused a £3 million offer. Further negotiations were curtailed abruptly after he broke a leg at Cameroon's pre-World Cup training camp, and missed the 1998 World Cup. Shortly after his recovery, he moved to English Premier League club West Ham United, for a club record £4.2 million in January 1999. He played 38 league matches for West Ham, scoring one goal against Sheffield Wednesday. He also scored a goal in West Ham's 3–1 win against NK Osijek in the UEFA Cup. In May 2000, he moved back to France, joining Lyon on a £6 million transfer. He missed much of the season from malaria. After recovery, he won the Coupe de la Ligue in 2001, and the Division 1 league title a year later. He was on the Cameroon squad in the 2002 World Cup. As in 1994, he played in all of Cameroon's matches. Though the team performed better since 1994, they were again eliminated. At the group stage, they beat Saudi Arabia, drew with Ireland and lost to Germany. Foé returned to the Premier League, loaned to Manchester City in the 2002–03 season for £550,000. His debut on the opening day of the season was a 3–0 loss to Leeds United. Foé was a first team regular for Kevin Keegan's team, starting 38 of 41 matches.

He graduated in ecclesiastical law at the late age of 20 and began to practice. Soon after, he dedicated himself to physics and mathematics (then called \"positive philosophy\"), and in 1809 started teaching them at a \"liceo\" (high school) in Vercelli, where his family lived and had some property. In 1811, he published an article with the title \"Essai d'une manière de déterminer les masses relatives des molécules élémentaires des corps, et les proportions selon lesquelles elles entrent dans ces combinaisons\" (\"Essay on a manner of Determining the Relative Masses of the Elementary Molecules of Bodies and the Proportions by Which They Enter These Combinations\"), which contains Avogadro's hypothesis. Avogadro submitted this essay to Jean-Claude Delamétherie's \"Journal de Physique, de Chimie et d'Histoire naturelle\" (\"Journal of Physics, Chemistry and Natural History\"). In 1820, he became a professor of physics at the University of Turin. Turin was now the capital of the restored Savoyard Kingdom of Sardinia under Victor Emmanuel I. Avogadro was active in the revolutionary movement of March 1821. As a result, he lost his chair in 1823 (or, as the university officially declared, it was \"very glad to allow this interesting scientist to take a rest from heavy teaching duties, in order to be able to give better attention to his researches\"). Eventually, King Charles Albert granted a Constitution (\"Statuto Albertino\") in 1848. Well before this, Avogadro had been recalled to the university in Turin in 1833, where he taught for another twenty years. Little is known about Avogadro's private life, which appears to have been sober and religious. He married Felicita Mazzé and had six children. Avogadro held posts dealing with statistics, meteorology, and weights and measures (he introduced the metric system into Piedmont) and was a member of the Royal Superior Council on Public Instruction. He died on 9 July 1856.", "section_level": 1}, {"title": "Accomplishments.", "content": "In honor of Avogadro's contributions to molecular theory, the number of molecules per mole of substance is named the \"Avogadro constant\", \"N\". It is exactly The Avogadro constant is used to compute the results of chemical reactions. It allows chemists to determine the amounts of substances produced in a given reaction to a great degree of accuracy. Johann Josef Loschmidt first calculated the value of the Avogadro constant, the number of particles in one mole, sometimes referred to as the Loschmidt number in German-speaking countries (Loschmidt constant now has another meaning). Avogadro's Law states that the relationship between the masses of the same volume of all gases (at the same temperature and pressure) corresponds to the relationship between their respective molecular weights. Hence, the relative molecular mass of a gas can be calculated from the mass of a sample of known volume. Avogadro developed this hypothesis after Joseph Louis Gay-Lussac published his law on volumes (and combining gases) in 1808. The greatest problem Avogadro had to resolve was the confusion at that time regarding atoms and molecules. One of his most important contributions was clearly distinguishing one from the other, stating that gases are composed of molecules, and these molecules are composed of atoms. (For instance, John Dalton did not consider this possibility.) Avogadro did not actually use the word \"atom\" as the words \"atom\" and \"molecule\" were used almost without difference. He believed that there were three kinds of \"molecules,\" including an \"elementary molecule\" (our \"atom\"). Also, he gave more attention to the definition of mass, as distinguished from weight. In 1815, he published \"Mémoire sur les masses relatives des molécules des corps simples, ou densités présumées de leur gaz, et sur la constitution de quelques-uns de leur composés, pour servir de suite à l'Essai sur le même sujet, publié dans le Journal de Physique, juillet 1811\" (\"Note on the Relative Masses of Elementary Molecules, or Suggested Densities of Their Gases, and on the Constituents of Some of Their Compounds, As a Follow-up to the Essay on the Same Subject, Published in the Journal of Physics, July 1811\") about gas densities. In 1821 he published another paper, \"Nouvelles considérations sur la théorie des proportions déterminées dans les combinaisons, et sur la détermination des masses des molécules des corps\" (\"New Considerations on the Theory of Proportions Determined in Combinations, and on Determination of the Masses of Atoms\") and shortly afterwards, \"Mémoire sur la manière de ramener les composès organiques aux lois ordinaires des proportions déterminées\" (\"Note on the Manner of Finding the Organic Composition by the Ordinary Laws of Determined Proportions\").

Only through studies by Charles Frédéric Gerhardt and Auguste Laurent on organic chemistry was it possible to demonstrate that Avogadro's law explained why the same quantities of molecules in a gas have the same volume. Unfortunately, related experiments with some inorganic substances showed seeming contradictions. This was finally resolved by Stanislao Cannizzaro, as announced at Karlsruhe Congress in 1860, four years after Avogadro's death. He explained that these exceptions were due to molecular dissociations at certain temperatures, and that Avogadro's law determined not only molecular masses, but atomic masses as well. In 1911, a meeting in Turin commemorated the hundredth anniversary of the publication of Avogadro's classic 1811 paper. King Victor Emmanuel III attended, and Avogadro's great contribution to chemistry was recognized. Rudolf Clausius, with his kinetic theory on gases proposed in 1857, provided further evidence for Avogadro's Law.

Scientists in this field conduct research concerned with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis, as well as how these interactions are regulated. A great variety of techniques are used to answer these questions. Fluorescent imaging techniques, as well as electron microscopy, x-ray crystallography, NMR spectroscopy, atomic force microscopy (AFM) and small-angle scattering (SAS) both with X-rays and neutrons (SAXS/SANS) are often used to visualize structures of biological significance. Protein dynamics can be observed by neutron spin echo spectroscopy. Conformational change in structure can be measured using techniques such as dual polarisation interferometry, circular dichroism, SAXS and SANS. Direct manipulation of molecules using optical tweezers or AFM, can also be used to monitor biological events where forces and distances are at the nanoscale. Molecular biophysicists often consider complex biological events as systems of interacting entities which can be understood e.g. through statistical mechanics, thermodynamics and chemical kinetics. By drawing knowledge and experimental techniques from a wide variety of disciplines, biophysicists are often able to directly observe, model or even manipulate the structures and interactions of individual molecules or complexes of molecules. In addition to traditional (i.e. molecular and cellular) biophysical topics like structural biology or enzyme kinetics, modern biophysics encompasses an extraordinarily broad range of research, from bioelectronics to quantum biology involving both experimental and theoretical tools.

Medical physics, a branch of biophysics, is any application of physics to medicine or healthcare, ranging from radiology to microscopy and nanomedicine. For example, physicist Richard Feynman theorized about the future of nanomedicine. He wrote about the idea of a \"medical\" use for biological machines (see nanomachines). Feynman and Albert Hibbs suggested that certain repair machines might one day be reduced in size to the point that it would be possible to (as Feynman put it) \"swallow the doctor\".

Morris started his career after college drawing in the Compagnie Belge d'Actualités (CBA) animation studios. This was a small and short-lived Belgian animation studio, where he met fellow artists Peyo and André Franquin. After World War II, the company folded. Morris worked as an illustrator for \"Het Laatste Nieuws\", a Flemish newspaper, and \"Le Moustique\", a French-language weekly magazine published by Dupuis.

Lucky Luke is a solitary cowboy who travels across the Wild West of the United States, helping those in need and aided by his faithful horse, Jolly Jumper. The first adventure, \"Arizona 1880\", was published in \"L'Almanach Spirou 1947\", released on 7 December 1946. Morris became one of the central artists of the magazine. He was one of the so-called \"La bande des quatre\" (Gang of 4), with Jijé, André Franquin, and Will. He did not work at Jijé's studio, unlike the other two, but all four became very good friends, stimulating each other artistically. In 1948, Morris, Jijé and Franquin travelled to the United States (Will was still too young and had to remain in Belgium). They wanted to get to know the country, see what was left of the Wild West, and meet some American comic artists. Morris stayed the longest of the three, for six years. During his six-year stay in the U.S. Morris met Jack Davis and Harvey Kurtzman, and assisted them with founding their \"Mad\" magazine at EC Comics. In the U.S. he also met René Goscinny, a French comic artist and writer. They developed a long collaboration, and Goscinny wrote all the \"Lucky Luke\" stories between 1955 and his death in 1977. In the 1950s, Goscinny was still fairly unknown, but he became the most successful comic writer in Europe, first with \"Lucky Luke\" and a few years later with his \"Asterix\" series. Morris's time in the USA were integral to his development, not only because of his collaboration with Goscinny, but because he gathered a great deal of documentation for his later work. He also became familiar with the Hollywood films of the time. In the following years, Morris introduced many cinematic techniques in his comics, such as freeze-frames and close-ups. Walt Disney's style influenced him, which can be seen in the very round lines that characterize the early Lucky Luke albums. Many characters in his comics are also clearly based on famous American actors, such as Jack Palance, Gary Cooper, W.C. Fields, and William Hart. He also caricatured unexpected figures, such as Louis de Funès and French singer Serge Gainsbourg. The first 31 Lucky Luke adventures were published by Dupuis. In the late 1960s, Morris left Dupuis and \"Spirou\" and went to Dargaud and \"Pilote\" magazine. This was started by his friend and collaborator Goscinny. In 1984, Hanna-Barbera made a series of 52 cartoons of \"Lucky Luke\", increasing the popularity of the series. 52 more animated cartoons were made in the early 1990s, and three live action movies followed. A few videogames based on the series were also made, e.g. for PlayStation and Game Boy Color. \"Lucky Luke\" is the best-selling European comics series ever, with more than 300 million copies sold, and published in more than thirty languages. Unlike many of his contemporaries, Morris never worked on several series. He made numerous illustrations for stories in the forties and fifties. In the nineties, he did make \"Rantanplan\", a spin-off from \"Lucky Luke\", starring the dumbest dog in the West.

Because of technological constraints or artistic requirements, the image may represent the scene over a period of time. Most often this exposure time is brief enough that the image captured by the camera appears to capture an instantaneous moment, but this is not always so, and a fast moving object or a longer exposure time may result in blurring artifacts which make this apparent. As objects in a scene move, an image of that scene must represent an integration of all positions of those objects, as well as the camera's viewpoint, over the period of exposure determined by the shutter speed. In such an image, any object moving with respect to the camera will look blurred or smeared along the direction of relative motion. This smearing may occur on an object that is moving or on a static background if the camera is moving. In a film or television image, this looks natural because the human eye behaves in much the same way. Because the effect is caused by the relative motion between the camera, and the objects and scene, motion blur may be manipulated by panning the camera to track those moving objects. In this case, even with long exposure times, the moving objects will appear sharper while the background will become more blurred, with the resulting image conveying a sense of movement and speed.", "section_level": 2}, {"title": "Animation.", "content": "In computer animation this effect must be simulated as a virtual camera actually does capture a discrete moment in time. This simulated motion blur is typically applied when either the camera or objects in the scene move rapidly. Without this simulated effect each frame shows a perfect instant in time (analogous to a camera with an infinitely fast shutter), with zero motion blur. This is why a video game with a frame rate of 25-30 frames per second will seem staggered, while natural motion filmed at the same frame rate appears rather more continuous. Many modern video games feature motion blur, especially vehicle simulation games. Some of the better-known games that utilise this are the recent Need for Speed titles, Unreal Tournament III,, among many others. There are two main methods used in video games to achieve motion blur: cheaper full-screen effects, which typically only take camera movement (and sometimes how fast the camera is moving in 3-D Space to create a radial blur) into mind, and more \"selective\" or \"per-object\" motion blur, which typically uses a shader to create a velocity buffer to mark motion intensity for a motion blurring effect to be applied to or uses a shader to perform geometry extrusion. Classic \"motion blur\" effects prior to modern per-pixel shading pipelines often simply drew successive frames on top of each other with slight transparency, which is strictly speaking a form of video feedback. In pre-rendered computer animation, such as CGI movies, realistic motion blur can be drawn because the renderer has more time to draw each frame. Temporal anti-aliasing produces frames as a composite of many instants. Frames are not points in time, they are periods of time. If an object makes a trip at a linear speed along a path from 0% to 100% in four time periods, and if those time periods are considered frames, then the object would exhibit motion blur streaks in each frame that are 25% of the path length. If the shutter speed is shortened to less than the duration of a frame, and it may be so shortened as to approach zero time in duration, then the computer animator must choose which portion of the quarter paths (in our 4 frame example) they wish to feature as \"open shutter\" times. They may choose to render the beginnings of each frame, in which case they will never see the arrival of the object at the end of the path, or they may choose to render the ends of each frame, in which case they will miss the starting point of the trip. Most computer animations systems make the classic \"fence-post error\" in the way they handle time, confusing the periods of time of an animation with the instantaneous moments that delimit them. Thus most computer animation systems will incorrectly place an object on a four frame trip along a path at 0%, 0.33%, 0.66%, and 1.0% and when called upon to render motion blur will have to cut one or more frames short, or look beyond the boundaries of the animation, compromises that real cameras don't do and synthetic cameras needn't do. Motion lines in cel animation are drawn in the same direction as motion blur and perform much the same duty. Go motion is a variant of stop motion animation that moves the models during the exposure to create a less staggered effect.", "section_level": 2}, {"title": "Computer graphics.", "content": "In 2D computer graphics, motion blur is an artistic filter that converts the digital image/bitmap/raster image in order to simulate the effect.

To cope with this, humans generally alternate between saccades (quick eye movements) and fixation (focusing on a single point). Saccadic masking makes motion blur during a saccade invisible. Similarly, smooth pursuit allows the eye to track a target in rapid motion, eliminating motion blur of that target instead of the scene.", "section_level": 2}, {"title": "Negative effects of motion blur.", "content": "In televised sports, where conventional cameras expose pictures 25 or 30 times per second, motion blur can be inconvenient because it obscures the exact position of a projectile or athlete in slow motion. For this reason special cameras are often used which eliminate motion blurring by taking rapid exposures on the order of 1 millisecond, and then transmitting them over the course of the next 30 to 40 milliseconds. Although this gives sharper slow motion replays it can look strange at normal speed because the eye expects to see motion blurring and is not provided with blurred images. Conversely, extra motion blur can unavoidably occur on displays when it is not desired. This occurs with some video displays (especially LCD) that exhibits motion blur during fast motion. This can lead to more perceived motion blurring above and beyond the preexisting motion blur in the video material. See display motion blur. Sometimes, motion blur can be removed from images with the help of deconvolution. In video games the use or not of motion blur is somewhat controversial. Some gamers claim that the blur actually makes gaming worse since it does blur images, making more difficult to recognize objects, especially in fast-paced moments. This does become noticeable the lower the frame rate is. Improvements in the visual quality of modern post-process motion blur shaders as well as a tendency towards high frame rate video games has lessened the visual detriment of undersampled motion blur effects.", "section_level": 1}, {"title": "Restoration.", "content": "An example of blurred image restoration with Wiener deconvolution:", "section_level": 1}], "src_summary": "Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation.

Though much of John XXI's brief papacy was dominated by the powerful Cardinal Giovanni Gaetano Orsini, who succeeded him as Pope Nicholas III, John attempted to launch a crusade for the Holy Land, pushed for a union with the Eastern church, and did what he could to maintain peace between the Christian nations.

Online collaborative gaming software began between early networked computer users. In 1975, Will Crowther created Colossal Cave Adventure on a DEC PDP-10 computer. As internet connections grew, so did the numbers of users and multi-user games. In 1978 Roy Trubshaw, a student at University of Essex in the United Kingdom, created the game MUD (Multi-User Dungeon).

One of the first robust applications was the Navy's Common Operational Modeling, Planning and Simulation Strategy (COMPASS). The COMPASS system allowed up to 6 users to create point-to-point connections with one another; the collaborative session only remained while at least one user stayed active, and would have to be recreated if all six logged out. MITRE improved on that model by hosting the collaborative session on a server that each user logged into.

At the request of his father-in-law, Bernoulli began the voyage back to his home town of Basel in 1705. Just after setting out on the journey he learned of his brother's death to tuberculosis. Bernoulli had planned on becoming the professor of Greek at Basel University upon returning but instead was able to take over as professor of mathematics, his older brother's former position. As a student of Leibniz's calculus, Bernoulli sided with him in 1713 in the Leibniz–Newton debate over who deserved credit for the discovery of calculus. Bernoulli defended Leibniz by showing that he had solved certain problems with his methods that Newton had failed to solve. Bernoulli also promoted Descartes' vortex theory over Newton's theory of gravitation. This ultimately delayed acceptance of Newton's theory in continental Europe. In 1724, Johann Bernoulli entered a competition sponsored by the French Académie Royale des Sciences, which posed the question: In defending a view previously espoused by Leibniz, he found himself postulating an infinite external force required to make the body elastic by overcoming the infinite internal force making the body hard. In consequence, he was disqualified for the prize, which was won by Maclaurin. However, Bernoulli's paper was subsequently accepted in 1726 when the Académie considered papers regarding elastic bodies, for which the prize was awarded to Pierre Mazière. Bernoulli received an honourable mention in both competitions.", "section_level": 2}, {"title": "Disputes and controversy.", "content": "Although Johann and his brother Jacob Bernoulli worked together before Johann graduated from Basel University, shortly after this, the two developed a jealous and competitive relationship. Johann was jealous of Jacob's position and the two often attempted to outdo each other. After Jacob's death Johann's jealousy shifted toward his own talented son, Daniel. In 1738 the father–son duo nearly simultaneously published separate works on hydrodynamics. Johann attempted to take precedence over his son by purposely and falsely predating his work two years prior to his son's. The Bernoulli brothers often worked on the same problems, but not without friction. Their most bitter dispute concerned the brachistochrone curve problem, or the equation for the path followed by a particle from one point to another in the shortest amount of time, if the particle is acted upon by gravity alone. Johann presented the problem in 1696, offering a reward for its solution. Entering the challenge, Johann proposed the cycloid, the path of a point on a moving wheel, also pointing out the relation this curve bears to the path taken by a ray of light passing through layers of varied density. Jacob proposed the same solution, but Johann's derivation of the solution was incorrect, and he presented his brother Jacob's derivation as his own. Bernoulli was hired by Guillaume de l'Hôpital for tutoring in mathematics. Bernoulli and l'Hôpital signed a contract which gave l'Hôpital the right to use Bernoulli's discoveries as he pleased. L'Hôpital authored the first textbook on infinitesimal calculus, \"Analyse des Infiniment Petits pour l'Intelligence des Lignes Courbes\" in 1696, which mainly consisted of the work of Bernoulli, including what is now known as l'Hôpital's rule.

Following his father's wish, he studied theology and entered the ministry. But contrary to the desires of his parents, he also studied mathematics and astronomy. He traveled throughout Europe from 1676 to 1682, learning about the latest discoveries in mathematics and the sciences under leading figures of the time. This included the work of Johannes Hudde, Robert Boyle, and Robert Hooke. During this time he also produced an incorrect theory of comets. Bernoulli returned to Switzerland, and began teaching mechanics at the University of Basel from 1683. His doctoral dissertation \"Solutionem tergemini problematis\" was submitted in 1684. It appeared in print in 1687. In 1684 Bernoulli married Judith Stupanus; they had two children. During this decade, he also began a fertile research career. His travels allowed him to establish correspondence with many leading mathematicians and scientists of his era, which he maintained throughout his life. During this time, he studied the new discoveries in mathematics, including Christiaan Huygens's \"De ratiociniis in aleae ludo\", Descartes' \"La Géométrie\" and Frans van Schooten's supplements of it. He also studied Isaac Barrow and John Wallis, leading to his interest in infinitesimal geometry. Apart from these, it was between 1684 and 1689 that many of the results that were to make up \"Ars Conjectandi\" were discovered. He was appointed professor of mathematics at the University of Basel in 1687, remaining in this position for the rest of his life. By that time, he had begun tutoring his brother Johann Bernoulli on mathematical topics. The two brothers began to study the calculus as presented by Leibniz in his 1684 paper on the differential calculus in \"Nova Methodus pro Maximis et Minimis\" published in \"Acta Eruditorum\". They also studied the publications of von Tschirnhaus. It must be understood that Leibniz's publications on the calculus were very obscure to mathematicians of that time and the Bernoullis were among the first to try to understand and apply Leibniz's theories. Jacob collaborated with his brother on various applications of calculus. However the atmosphere of collaboration between the two brothers turned into rivalry as Johann's own mathematical genius began to mature, with both of them attacking each other in print, and posing difficult mathematical challenges to test each other's skills. By 1697, the relationship had completely broken down. The lunar crater Bernoulli is also named after him jointly with his brother Johann.", "section_level": 1}, {"title": "Important works.", "content": "Jacob Bernoulli's first important contributions were a pamphlet on the parallels of logic and algebra published in 1685, work on probability in 1685 and geometry in 1687. His geometry result gave a construction to divide any triangle into four equal parts with two perpendicular lines. By 1689 he had published important work on infinite series and published his law of large numbers in probability theory. Jacob Bernoulli published five treatises on infinite series between 1682 and 1704 The first two of these contained many results, such as the fundamental result that formula_1 diverges, which Bernoulli believed were new but they had actually been proved by Mengoli 40 years earlier. Bernoulli could not find a closed form for formula_2, but he did show that it converged to a finite limit less than 2. Euler was the first to find the sum of this series in 1737. Bernoulli also studied the exponential series which came out of examining compound interest. In May 1690 in a paper published in \"Acta Eruditorum\", Jacob Bernoulli showed that the problem of determining the isochrone is equivalent to solving a first-order nonlinear differential equation. The isochrone, or curve of constant descent, is the curve along which a particle will descend under gravity from any point to the bottom in exactly the same time, no matter what the starting point. It had been studied by Huygens in 1687 and Leibniz in 1689. After finding the differential equation, Bernoulli then solved it by what we now call separation of variables. Jacob Bernoulli's paper of 1690 is important for the history of calculus, since the term integral appears for the first time with its integration meaning. In 1696 Bernoulli solved the equation, now called the Bernoulli differential equation, Jacob Bernoulli also discovered a general method to determine evolutes of a curve as the envelope of its circles of curvature. He also investigated caustic curves and in particular he studied these associated curves of the parabola, the logarithmic spiral and epicycloids around 1692. The lemniscate of Bernoulli was first conceived by Jacob Bernoulli in 1694. In 1695 he investigated the drawbridge problem which seeks the curve required so that a weight sliding along the cable always keeps the drawbridge balanced. Jacob Bernoulli's most original work was \"Ars Conjectandi\" published in Basel in 1713, eight years after his death. The work was incomplete at the time of his death but it is still a work of the greatest significance in the theory of probability. In the book Bernoulli reviewed work of others on probability, in particular work by van Schooten, Leibniz, and Prestet. The Bernoulli numbers appear in the book in a discussion of the exponential series. Many examples are given on how much one would expect to win playing various games of chance. The term Bernoulli trial resulted from this work. There are interesting thoughts on what probability really is: ... probability as a measurable degree of certainty; necessity and chance; moral versus mathematical expectation; a priori an a posteriori probability; expectation of winning when players are divided according to dexterity; regard of all available arguments, their valuation, and their calculable evaluation; law of large numbers...

Compounding quarterly yields $1.00×1.25 = $2.4414..., and compounding monthly yields $1.00×(1.0833...) = $2.613035... Bernoulli noticed that this sequence approaches a limit (the force of interest) for more and smaller compounding intervals. Compounding weekly yields $2.692597..., while compounding daily yields $2.714567..., just two cents more. Using as the number of compounding intervals, with interest of 100%/ in each interval, the limit for large is the number that Euler later named ; with \"continuous\" compounding, the account value will reach $2.7182818...

By 1910 bandoneons were being produced expressly for the Argentine and Uruguayan markets, with 25,000 shipping to Argentina in 1930 alone. However, declining popularity and the disruption of German manufacturing in World War II led to an end of bandoneon mass-production. Original instruments can be seen in a number of German museums, such as the Preuss family's Bandoneon Museum in Lichtenberg and the Steinhart family's collection in Kirchzarten, Freiburg. Historically, bandoneons were produced primarily in Germany and never in Argentina itself, despite their popularity in that country.

This means that each keyboard actually has two layouts: one for opening notes, and one for closing notes.

He was highly esteemed, however, by those who wanted to reform the Church, and was one of five men proposed by Cardinal Frederick of Lorraine when consulted during the summer of 1057 concerning a possible successor to Pope Victor II, whom Frederick himself succeeded as Pope Stephen IX. Upon Pope Stephen's death the following year, Giovanni was elected pope on 4 April 1058, his election having been arranged by his family. This was in violation, however, of a decree by the late pope that no election was to be held until the return of Cardinal Hildebrand from a mission to Germany. Hildebrand (later Pope Gregory VII) had been sent by the late Pope Stephen to the court of Empress Agnes, who had questioned the validity of Stephen's own election. As a result, a number of cardinals alleged that the election was irregular. These cardinals were soon forced to flee Rome. When Hildebrand heard of Benedict's election during his return journey to Rome, he decided to oppose it. He went to Florence where he obtained the support of the Duke of Lorraine and Tuscany for the election of Gerhard of Burgundy, Archbishop of Florence, as pope instead. Support for this was given by Empress Agnes. Those cardinals who had opposed Benedict's election met at Siena in December 1058, and elected Gerhard, who then took the name of Nicholas II. Nicholas then proceeded towards Rome, along the way holding a synod at Sutri, where he pronounced Benedict deposed and excommunicated. The supporters of Nicholas then gained control of Rome, and forced Benedict to flee to the castle of Count Gerard of Galeria. Having arrived in Rome, Nicholas was crowned as pope on 24 January 1059. He then proceeded to wage war against Benedict and his supporters, with the assistance of Norman forces based in southern Italy, after he agreed to recognize Count Richard of Aversa as ruler of Capua. An initial battle was fought in Campagna in early 1059, which was not wholly successful for Nicholas; but later that same year, his forces conquered Praeneste, Tusculum and Numentanum, and then attacked Galéria, forcing Benedict to surrender and to renounce the papacy in the Fall of that year. Benedict was allowed to go free, and he retired to one of his family's estates in the city. Pope Nicholas, however, deemed his submission inadequate and had him publicly tried in 1060, with Hildebrand serving as his prosecutor. Despite pleading that he had been forced to assume the papal crown, he was convicted that April and stripped of all his titles. He was further sentenced to confinement in the hospital attached to the Basilica of Sant'Agnese fuori le mura, where he died, still a prisoner, sometime between 1073 and 1080. He was likely buried in the adjoining church. The most important consequence of these events was the adoption of new regulations for papal elections, laid out at a synod called by Pope Nicholas in the Lateran Palace on Easter 1059.

The Netherlands at this time was engaged in the Eighty Years' War against Spain for its independence. Under Frederick Henry, the Netherlands had largely won the war, and since 1646 had been negotiating with Spain on the terms for ending it. The negotiators agreed to the Peace of Münster in 1648, but William opposed acceptance of the treaty, even though it recognized the independence of the (northern) Netherlands, because it left the southern Netherlands in the hands of the Spanish monarchy. A separate peace furthermore violated the alliance with France formed in 1635. However, the States of six provinces voted to accept it. Secretly, William opened his own negotiations with France with the goal of extending his own territory under a more centralized government. In addition, he worked for the restoration of his exiled brother-in-law, Charles II, to the throne of England. In 1650 William II became involved in a bitter quarrel with the province of Holland and the powerful Regents of Amsterdam, Andries Bicker and his cousin Cornelis de Graeff. With the Peace of Münster, the Regents wanted to reduce the army, saving money. That would also diminish William's authority. William imprisoned eight members of the States of Holland (including Jacob de Witt) in the castle of Loevestein. In addition, he sent his cousin, Willem Frederik of Nassau-Dietz with an army of 10,000 men to seize Amsterdam by force. Bad weather foiled this campaign, but Amsterdam did give in. William served as stadtholder for only three years, until he died of smallpox in 1650. His only son William was born one week after his death.

She probably took it as a recognition of Philip's victory in the Olympic Games of 356 BC, the news of which coincided with Alexander's birth (Plut. Alexander 3.8).

The alliance was cemented with a diplomatic marriage between Arymbas' niece, Olympias, and Philip in 357 BC. It made Olympias the queen consort of Macedonia, and Philip the king. Philip had allegedly fallen in love with Olympias when both were initiated into the mysteries of Cabeiri at the Sanctuary of the Great Gods, on the island of Samothrace, though their marriage was largely political in nature. One year later, in 356 BC, Philip's race horse won in the Olympic Games; for this victory, his wife, who was known then as Myrtale, received the name \"Olympias\". In the summer of the same year, Olympias gave birth to her first child, Alexander. In ancient Greece people believed that the birth of a great man was accompanied by portents. As Plutarch describes, the night before the consummation of their marriage, Olympias dreamed that a thunderbolt fell upon her womb and a great fire was kindled, its flames dispersed all about and then were extinguished. After the marriage Philip dreamed that he put a seal upon his wife's womb, the device of which was the figure of a lion. Aristander's interpretation was that Olympias was pregnant of a son whose nature would be bold and lion-like. Philip and Olympias also had a daughter, Cleopatra, who later married her uncle, Alexander I of Epirus, to further diplomatic ties between Macedonia and Epirus. According to primary sources, their marriage was very stormy due to Philip's volatility and Olympias' ambition and alleged jealousy, which led to their growing estrangement. Things got more tumultuous in 337 BC when Philip married a noble Macedonian woman, Cleopatra, the niece of Attalus, who was given the name Eurydice by Philip. At a gathering after the marriage, Philip failed to defend Alexander's claim to the Macedonian throne when Attalus threatened his legitimacy, causing great tensions between Philip, Olympias, and Alexander. Olympias went into voluntary exile in Epirus along with Alexander, staying at the Molossian court of her brother Alexander I, who was the king at the time. In 336 BC, Philip cemented his ties to Alexander I of Epirus by offering him the hand of his and Olympias' daughter Cleopatra in marriage, a fact that led Olympias to further isolation as she could no longer count on her brother's support.

The relationship between Olympias and Alexander was cordial, but her son tried to keep her away from politics. However, she wielded great influence in Macedonia and caused troubles to Antipater, the regent of the kingdom. In 330 BC, she returned to Epirus and served as a regent to her cousin Aeacides in the Epirote state, as her brother Alexander I had died during a campaign in southern Italy. After Alexander the Great's death in Babylon in 323 BC, his wife Roxana gave birth to their son named Alexander IV. Alexander IV and with his uncle Philip III Arrhidaeus, the half brother of Alexander the Great who may have been disabled, were subject to the regency of Perdiccas, who tried to strengthen his position through a marriage with Antipater's daughter Nicaea. At the same time, Olympias offered Perdiccas the hand of her and Philip's daughter, Cleopatra. Perdiccas chose Cleopatra, which angered Antipater, who allied himself with several other Diadochi, deposed Perdiccas, and was declared regent, only to die within the year. Polyperchon succeeded Antipater in 319 BC as regent, but Antipater's son Cassander established Philip II's son Philip III (Arrhidaeus) as king and forced Polyperchon out of Macedonia. He fled to Epirus, taking Roxana and her son Alexander IV with him, who had previously been left in the care of Olympias. At the beginning, Olympias had not been involved in this conflict, but she soon realized that in the case of Cassander's rule, her grandson would lose the crown, so she allied with Polyperchon in 317 BC. The Macedonian soldiers supported her return and the united armies of Polyperchon and Olympias, with the house of Aeacides, invaded Macedonia to drive Cassander out from power. After winning in battle by convincing the army of Adea Eurydice, the wife of Philip III, to side with her own, Olympias captured and executed the two in October 317 BC. She also captured Cassander's brother and a hundred of his partisans. Cassander soon blockaded and besieged Olympias in Pydna and one of the terms of the capitulation had been that Olympias's life would be saved, but Cassander had decided to execute her, sparing only temporarily the lives of Roxana and Alexander IV (they were executed a few years later in 309 BC). When the fortress of Pydna fell, Cassander ordered Olympias killed, but the soldiers refused to harm the mother of Alexander the Great.

Ireland was known in Latin as \"Scotia Major\"; therefore, in German, Irish monks were called \"\"Schotten\"\" (Scots) or \"\"Iroschotten\"\". The monasteries that they founded were called \"\"Schottenklöster\"\". In the foundation documents of the Schottenstift, Henry II specified that it was to be occupied exclusively by these \"Iroschotten\" (\"Solos elegimus Scottos\"). Henry II was elevated from the rank of Margrave (\"Markgraf\") to that of Duke (\"Herzog\") in 1156. He moved his residence from Klosterneuburg to Vienna and required a monastery for his new city. In the Middle Ages, monasteries were not only places for prayer, but also and above all, repositories of knowledge. The foundation of a monastery gave the ruler support for his administration (for example, schools to educate competent scribes). It also provided a library, a hospice and old age home, architects, educated men, and priests to conduct services in the new ducal city. The \"\"Schotten\"\" would also be involved with the University of Vienna, which was founded in 1365. Henry granted the new monastery extensive privileges. Construction of the first monastery started in 1160, and the structure was consecrated in 1200. The monastery was outside the city walls of Vienna. The monks also built a hospice for pilgrims and crusaders, who often passed through Vienna on their way to Jerusalem. The first church was a three-aisled, Romanesque, pillar church with a single apse. Henry II was buried there upon his death in 1177. A fire in the year 1276 destroyed the cloister, along with many other buildings in Vienna. In 1418, Duke Albert V seized the cloister during the Melker Reform, an attempt to revive the original ideals of Benedictine monasticism, and settled a community of Benedictines in their place. These new residents, however, continued to be known as the \"\"Schotten\"\". In the middle of the 15th century, the monastery was distinguished through the literary activities of its schoolmaster, Wolfgang Schmeltzl, and his successor, Johannes Rasch. The collapse of the tower, struck by a lightning bolt in 1638, was seized as an opportunity to completely rebuild the church, a project undertaken by the architects Andrea d'Allio the Younger and Silvestro Carlone. The church was somewhat shortened, and the tower no longer stood directly beside the basilica. Joachim von Sandrart provided the church with a new altar piece, which today is kept in the prelates' hall. After the Turkish siege, the church was restored. As the Baroque west tower was barely higher than the façade itself, its extension has often been proposed, but this has never come to fruition. Around 1700 the great Baroque musician Johann Fux was the organist at the Schottenstift. In 1773 and 1774, a new priory, with school, was built by Andreas Zach in the grounds of an open air cemetery. As it resembled a piece of furniture, it became popularly known as the \"Schubladkastenhaus\" (\"the chest-of-drawers house\"). Directly next door stood the \"Hotel Römischer Kaiser\", where the first public performance of a song by Franz Schubert was held. In 1807 the \"Schottengymnasium\", an institute for secondary education, was founded by imperial decree. Around 1830, the auxiliary buildings of the Abbey, in particular those that bordered on the Freyung, were renovated and partially rebuilt by Joseph Kornhäusel.

The same compound is responsible for the pungency of horseradish and mustard. Allyl isothiocyanate can also be released when the wasabi plants have been damaged, because it is being used as a defense mechanism. The unique flavor of wasabi is a result of complex chemical mixtures from the broken cells of the plant, including those resulting from the hydrolysis of thioglucosides from sinigrin into glucose and methylthioalkyl isothiocyanates: Research has shown that such isothiocyanates inhibit microbe growth, perhaps with implications for preserving food against spoilage and suppressing oral bacterial growth. Because the burning sensations of wasabi are not oil-based, they are short-lived compared to the effects of capsaicin in chili peppers, and are washed away with more food or liquid. The sensation is felt primarily in the nasal passage and can be quite painful depending on the amount consumed.

In this case this specifically involves amide bonds, and the two groups involved are an amine group, and a terminal carbonyl component of a functional group. These react to produce a carbon-nitrogen bond, creating a singular amide linkage. This process involves the elimination of other atoms previously part of the functional groups. The carbonyl-component may be part of either a carboxylic acid group or the more reactive acyl halide derivative. The amine group and the carboxylic acid group can be on the same monomer, or the polymer can be constituted of two different bifunctional monomers, one with two amine groups, the other with two carboxylic acid or acid chloride groups. The condensation reaction is used to synthetically produce nylon polymers in industry. Nylons must specifically include a straight chain (aliphatic) monomer. The amide link is produced from an amine group (alternatively known as an amino group), and a carboxylic acid group. The hydroxyl from the carboxylic acid combines with a hydrogen from the amine, and gives rise to water, the elimination byproduct that is the namesake of the reaction. As an example of condensation reactions, consider that in living organisms, Amino acids are condensed with one another by an enzyme to form amide linkages (known as peptides). The resulting polyamides are known as proteins or polypeptides. In the diagram below, consider the amino-acids as single aliphatic monomers reacting with identical molecules to form a polyamide, focusing on solely the amine and acid groups. Ignore the substituent R groups – under the assumption the difference between the R groups are negligible: For fully aromatic polyamides or 'aramids' e.g. Kevlar, the more reactive acyl chloride is used as a monomer. The polymerization reaction with the amine group eliminates hydrogen chloride. The acid chloride route can be used as a laboratory synthesis to avoid heating and obtain an almost instantaneous reaction. The aromatic moiety itself does not participate in elimination reaction, but it does increase the rigidity and strength of the resulting material which leads to Kevlar's renowned strength. In the diagram below, Aramid is made from two different monomers which continuously alternate to form the polymer. Aramid is an aromatic polyamide: Polyamides can also be synthesized from dinitriles using acid catalysis via an application of the Ritter reaction.

While working at a local mine, Sander first learned about photography by assisting a photographer who was working for a mining company. With financial support from his uncle, he bought photographic equipment and set up his own darkroom. He spent his military service (1897–99) as a photographer's assistant and the next years wandering across Germany. In 1901, he started working for a photo studio in Linz, Austria, eventually becoming a partner (1902), and then its sole proprietor (1904). He left Linz at the end of 1909 and set up a new studio in Cologne. In 1911, Sander began with the first series of portraits for his work \"People of the 20th Century\". In the early 1920s, he came in contact with the Cologne Progressives a radical group of artists linked to the workers' movement which, as put it, \"sought to combine constructivism and objectivity, geometry and object, the general and the particular, avant-garde conviction and political engagement, and which perhaps approximated most to the forward looking of New Objectivity [...] \".

The vas deferens loops over the ureter in placental mammals, but not in marsupial mammals. In cartilaginous fishes, the part of the archinephric duct closest to the testis is coiled up to form an epididymis. Below this are a number of small glands secreting components of the seminal fluid. The final portion of the duct also receives ducts from the kidneys in most species. In amniotes, however, the archinephric duct has become a true vas deferens, and is used only for conducting sperm, never urine. As in cartilaginous fish, the upper part of the duct forms the epididymis. In many species, the vas deferens ends in a small sac for storing sperm.

Images of the deity, quite different from those of the other gods, were kept in homes. Normally Egyptian gods were shown in profile, but instead Bes appeared in full face portrait, ithyphallic, and sometimes in a soldier's tunic, so as to appear ready to launch an attack on any approaching evil. He scared away demons from houses, so his statue was put up as a protector. Since he drove off evil, Bes also came to symbolize the good things in life – music, dance, and sexual pleasure. In the New Kingdom, tattoos of Bes could be found on the thighs of dancers, musicians and servant girls. Many instances of Bes masks and costumes from the New Kingdom and later have been uncovered. These show considerable wear, thought to be too great for occasional use at festivals, and are therefore thought to have been used by professional performers, or given out for rent. Later, in the Ptolemaic period of Egyptian history, chambers were constructed, painted with images of Bes and his wife Beset, thought by Egyptologists to have been for the purpose of curing fertility problems or general healing rituals. Like many Egyptian gods, the worship of Bes or Beset was exported overseas. While the female variant had been more popular in Minoan Crete, the male version would prove popular with the Phoenicians and the ancient Cypriots. The Balearic island of Ibiza derives its name from the god's name, brought along with the first Phoenician settlers in 654 BC. These settlers, amazed at the lack of any sort of venomous creatures on the island, thought it to be the island of Bes (<איבשם> \"ʔybšm\", \"*ʔibošim\", \"yibbōšīm\" \"dedicated to Bes\"). Later the Roman name Ebusus was derived from this designation. At the end of the 6th century BC, images of Bes began to spread across the Achaemenid Empire, which Egypt belonged to at the time.

He won all four Grand Slam junior titles in 1983 to become the first (and only) player to achieve the \"Junior Grand Slam\" in the open era. Later that year as a professional, Edberg won his first career doubles title in Basel. Edberg accidentally caused the death of linesman Dick Wertheim with an errant serve during the 1983 US Open. In 1984, Edberg won his first top-level singles title in Milan. Edberg also won the tennis tournament at the 1984 Summer Olympics when the sport was an exhibition event and partnered with fellow Swede Anders Järryd to reach the final of the US Open. Edberg also reached the French Open doubles final with Järryd in 1986 and consequently was world No. 1 in doubles in that year. U.S. fans first took notice of Edberg's professional career when he won the U.S. Indoor in Memphis in February 1985, defeating Yannick Noah in the final. Edberg's first two Grand Slam singles titles came at the Australian Open. In December 1985, he defeated Mats Wilander in straight sets to claim his first major title. In January 1987, he defended his title by defeating local favourite Pat Cash in five sets to win the last Australian Open held on grass courts. Edberg also won the Australian Open and US Open men's doubles titles in 1987 (partnering fellow Swede Anders Järryd). In 1988, Edberg reached the first of three consecutive finals at Wimbledon, but lost his ranking as Sweden's number-one-player when Mats Wilander had his best year by winning the Australian, French and US Opens, becoming the world's number-one-ranked player. In all three of his consecutive Wimbledon finals, Edberg played German Boris Becker in what became one of Wimbledon's greatest rivalries. Edberg won their first encounter in a four-set match spread over two days because of rain delays. A year later, Becker won in straight sets. The closest of their matches came in the 1990 final, when Edberg won in five sets after being down a break in the fifth set. Edberg reached the French Open final in 1989 but lost in five sets to 17-year-old Michael Chang, who became the youngest ever male winner of a Grand Slam singles title. This was the only Grand Slam singles title that Edberg never won, denying him the completion of a career Grand Slam at the senior level, to match his junior Grand Slam. In 1990, an abdominal muscle injury forced Edberg to retire from the Australian Open final while trailing Ivan Lendl 5–2 (including two breaks of serve) in the third set. Edberg nevertheless took the world No. 1 ranking from Lendl on 13 August 1990 by winning the Super 9 tournament in Cincinnati. He held it for the rest of that year and for much of 1991 and 1992. Edberg spent a total of 72 weeks as World No. 1. In 1991, Edberg again reached the semifinals of Wimbledon but lost to Michael Stich in a close match: 6–4, 6–7, 6–7, 6–7. Edberg's final two Grand Slam singles triumphs came at the US Open, with wins over Jim Courier in the 1991 final and Pete Sampras (who was just months away from attaining the world No. 1 ranking) in the 1992 final. Edberg reached the finals of the Australian Open again in 1992 and 1993, losing both times to Jim Courier in four sets. He was one of the few players who reached the finals of the Australian Open five times. The 1993 Australian Open final was Edberg's last Grand Slam singles final appearance. In 1996, Edberg reached the finals of Queens Club but lost the match to Boris Becker. He won his third and final Grand Slam doubles title at the Australian Open with Petr Korda.

After serving on the Eastern front, he was transferred to the Imperial German Army Air Service. Focke graduated in 1920 as Dipl-Ing with distinction.

In 1927 Wulf died while test flying the Focke-Wulf F 19 canard monoplane. In 1930 Focke was offered a chair at the Danzig Institute of Technology, an honour which he declined. In 1931 the city of Bremen awarded him the title of Professor. The same year, Focke-Wulf was merged with the Albatros Flugzeugwerke company. Focke-Wulf constructed Juan de la Cierva's C.19 and C.30 autogyros under license from 1933, and Focke was inspired by it to design the world's first practical helicopter, the Focke-Wulf Fw 61, which first flew on 26 June 1936 by Hanna Reitsch. In the Deutschlandhalle arena in 1938, it also became the first practical helicopter to be flown indoors. In 1936 Focke was ousted from the Focke-Wulf company by shareholder pressure. Though the ostensible reason was that he was considered \"politically unreliable\" by the Nazi regime, there is reason to believe it was so that Focke-Wulf's manufacturing capacity could be used to produce Bf 109 aircraft. The company was taken over by AEG, but soon after this the Air Ministry, which had been impressed by the Fw 61 helicopter, suggested that Focke establish a new company dedicated to helicopter development and issued him with a requirement for an improved design capable of carrying a payload. Focke established the Focke-Achgelis company on 27 April 1937 in partnership with pilot Gerd Achgelis, and began development work at Delmenhorst in 1938. The new company built the experimental Fa 225 using the fuselage of a DFS 230 glider and a rotor from a Fa 223. Another project was the Fa 330 kite with rotor, capable of being deployed by a submarine at a moments notice and then used as a towed spotter. It was stored in a watertight container on the deck of the U-boat and was used during the war. A powered version of the kite would have been the Fa 336 which was in the design phase when the war ended and built in France postwar for testing. Focke subsequently manufactured the heavy-lift transport helicopter Fa 223, and designed the Fa 224, Fa 266, Fa 269, Fa 283, Fa 284, and the Fa 336 during World War II. Only a few of the large Fa 223 \"Drache\" (\"Dragon\") helicopters actually were produced, but even the prototype set a new helicopter speed record of 182 km/h (113 mph) and climb record of 8.8 m/s (1,732 ft/min) in 1940. Subsequent war models were primarily used as mountain troop transport, rescue, and crashed aircraft recovery. The helicopter had provision for a nose-mounted machine gun, and could carry one or two bombs, but the \"Drache\" was never used for combat. Towards the end of the Third Reich Focke started design work on the Focke Rochen, also known as \"Schnellflugzeug\".", "section_level": 2}, {"title": "Postwar.", "content": "On 1 September 1945, Focke signed a contract with the French company SNCASE and assisted in development of their SE-3000 passenger helicopter, which was based on the Focke-Achgelis Fa 223 \"Drache\" and which first flew in 1948. In 1950, he worked as a designer with the North German Automobile Company (Norddeutsche Fahrzeugwerke) of Wilhelmshaven. In 1952, Focke and other members of his former design team were employed by Brazil's Centro Técnico Aeroespacial (CTA), at the time the air force's technical center, to develop a Convertiplane, the \"Convertiplano\", which drew heavily on Focke's wartime work on the Fa 269. Also recruited was Bussmann, a transmission specialist formerly of BMW. The Convertiplano was built using the fuselage and wings of a Supermarine Spitfire Mk 15, which was believed to be one delivered to Argentina as a sales example. Britain refused to supply the Armstrong Siddeley Double Mamba engine originally selected and the design was altered to accept a mid-mounted 2200 hp Wright engine instead as used in the Lockheed Constellation, which necessitated a redesign of the transmission due to the increase in weight and vibration. Some 40 workers and US$8 million were devoted to the project, and more than 300 takeoffs were achieved. While working at the CTA Focke also developed the BF-1 \"Beija-Flor\" (hummingbird) two-seater light helicopter from 1954, which made its first flight at Sao Jose dos Campos on 22 January 1959. The BF-1 was similar in design to the Cessna CH-1, with a 225 hp Continental E225 engine in the nose and the rotor mast running vertically between the front seats. An open structure tubular steel tail boom carried a pair of tail surfaces and a small tail rotor. The BF-2 was developed from this and first flew on 1 January 1959, and performed an extended flight-testing campaign until it was damaged in an accident. It is thought that further work on the \"Beija Flor\" was then abandoned. Focke returned permanently to Germany in 1956 and began developing a three-seater helicopter named the \"Kolibri\" (\"hummingbird\") at the Borgward company in Bremen, with its first flight taking place in 1958. While working at Borgward Focke set up a wind tunnel in a disused hangar in central Bremen; this wind tunnel was rediscovered in 1997 and is today the centerpiece of a museum devoted to him. After Borgward collapsed in 1961, Focke became a consulting engineer with Vereinigte Flugtechnische Werke of Bremen and Deutsche Forschungsanstalt für Luft-und Raumfahrt.

The area that encompasses Oak Island was once known as the \"Segepenegatig\" region. While it is unknown when Oak Island was first discovered, the tribe had a presence in the overall area which included the entire island of Newfoundland. The earliest confirmed European residents date back to the 1750s in the form of French fishermen, who had by this time built a few houses on the future site of the nearby village of Chester, Nova Scotia. Following the Expulsion of the Acadians during the Seven Years' War, the British government of Nova Scotia enacted a series of measures to encourage settlement of the area by the European-descended New Englanders. Land was made available to settlers in 1759 through the Shorham grant, and Chester was officially founded that same year. The first major group of settlers arrived in the Chester area from Massachusetts in 1761, and Oak Island was officially surveyed and divided into 32 four-acre lots in the following year. A large part of the island was owned at the time by the Monro, Lynch, Seacombe and Young families who had been granted the land in 1759. In the early days of British settlement, the Island was known locally as \"Smith's Island,\" after an early settler of the area named Edward Smith. Cartographer Joseph Frederick Wallet DesBarres renamed the Island \"Gloucester Isle\" in 1778. Shortly thereafter, the locally used name \"Oak Island\" was officially adopted for the Island. Early residents included Edward Smith in the 1760s and Anthony Vaughn Sr. in the early 1770s. In 1784, the government made additional land grants, this time to former soldiers, which included parts of Oak Island. It was not until July 6, 1818 that the original lot owners' names were mapped for the Nova Scotia Crown Lands office. Oak Island has been intermittently owned by treasure hunters ever since early settler stories started appearing in the late 1700s. The hunt for treasure got so extensive that in 1965 a causeway was built from the western end of the island to Crandall's Point on the mainland, two hundred metres away in order to bring heavy machinery onto the island. Oak Island has had several different recent owners which include a treasure hunter named Dan Blankenship, who initially partnered with \"Oak Island Tours Inc.\" run by David Tobias. Oak Island Tours eventually dissolved, and in February 2019, it was announced that a new partnership had been formed with a company called the \"Michigan Group\". This group consists of brothers Rick and Marty Lagina, Craig Tester, and Alan Kostrzewa who had been purchasing lots from Tobias. It is unclear who is involved to what degree as Blankenship only revealed Kostrzewa's name to the press saying he was \"on board\".

Since that time there have been many theories that extend beyond that of Captain Kidd which include among others religious artifacts, manuscripts, and Marie Antoinette's jewels. The \"treasure\" has also been prone to criticism by those who have dismissed search areas as natural phenomena. Areas of interest on the island with regard to treasure hunters include a location known as the \"Money Pit\", which is allegedly the original searchers’ spot. There is also a formation of boulders called \"Nolan's Cross\", named after a former treasure hunter with a theory on it, and a triangle-shaped swamp. Lastly, there has been searcher activity on a beach at a place called \"Smith's Cove\". Various objects including non-native coconut fibre have been found there. More recent archaeological discoveries in the 'Smith's Cove\" area have included an allegedly pre-15th century lead cross and various wooden earthworks. More than fifty books have been published recounting the island's history and exploring competing theories. Several works of fiction have also been based upon the Money Pit, including \"The Money Pit Mystery\", \"Riptide\", \"The Hand of Robin Squires\", and \"Betrayed: The Legend of Oak Island\".

These groups overlap and elites tend to circulate from one sector to another, consolidating power in the process. Unlike the ruling class, a social formation based on heritage and social ties, the power elite is characterized by the organizational structures through which its wealth is acquired. According to Mills, the power elite rose from \"the managerial reorganization of the propertied classes into the more or less unified stratum of the corporate rich\". Domhoff further clarified the differences in the two terms: \"The upper class as a whole does not do the ruling. Instead, class rule is manifested through the activities of a wide variety of organizations and institutions...Leaders within the upper class join with high-level employees in the organizations they control to make up what will be called the power elite\".

The basis for membership of a power elite is institutional power, namely an influential position within a prominent private or public organization. A study of the French corporate elite has shown that social class continues to hold sway in determining who joins this elite group, with those from the upper-middle class tending to dominate.

Sometime shortly before the year 1160, he was inspired by a series of events, firstly, after hearing a sermon on the life of St. Alexius, secondly, rejection of transubstantiation when it was considered a capital crime to do it, thirdly, the sudden and unexpected death of a friend during an evening meal. From this point onward he began living a radical Christian life, giving his property over to his wife, while the remainder of his belongings he distributed as alms to the poor. At about this time, Waldo began to preach and teach publicly, based on his ideas of simplicity and poverty, notably that \"No man can serve two masters, God and Mammon.\" Waldo condemned what he considered as papal excesses and Catholic dogmas, including purgatory and transubstantiation. He said that these dogmas were \"the harlot\" from the book of Revelation. By 1170 Waldo had gathered a large number of followers, referred to as \"the Poor of Lyons,\" \"the Poor of Lombardy,\" or \"the Poor of God.\" They evangelized their teaching while traveling as peddlers. Often referred to as the Waldensians (or Waldenses), they were distinct from the Albigensians or Cathari. The Waldensian movement was characterized from the beginning by lay preaching, voluntary poverty, and strict adherence to the Bible. Between 1170–80 Waldo commissioned a cleric from Lyon to translate the New Testament into the vernacular \"Romance\" (Franco-Provençal). He is credited with providing to Europe the first translation of the Bible in a'modern tongue' outside of Latin. In January 1179, Waldo and one of his disciples went to Rome, where they were welcomed by Pope Alexander III and the Roman Curia. They had to explain their faith before a panel of three clergymen, including issues which were then debated within the Church, such as the universal priesthood, the gospel in the vulgate or local language, and the issue of voluntary poverty. The results of the meeting were inconclusive. The pope affirmed his vow of poverty, but he was forbidden to continue preaching because he was a layperson. Waldo's ideas, but not the movement itself, were condemned at the Third Lateran Council in March of the same year. The leaders of the Waldensian movement were not yet excommunicated. In 1180, Waldo composed a profession of faith which is still extant. Driven away from Lyon, Waldo and his followers settled in the high valleys of Piedmont, and in France, in the Luberon, as they continued in their pursuit of Christianity based on the New Testament. Finally, Waldo was excommunicated by Pope Lucius III during the synod held at Verona in 1184. The doctrine of the Poor of Lyons was again condemned by the Fourth Lateran Council in 1215, when they mentioned the group by name for the first time, and declared its principles to be heresy.

The guild kept records of members and the marks they used on their products. These records, when they survive, are very useful to historians. Goldsmiths often acted as bankers, since they dealt in gold and had sufficient security for the safe storage of valuable items. In the Middle Ages, goldsmithing normally included silversmithing as well, but the brass workers and workers in other base metals normally were members of a separate guild, since the trades were not allowed to overlap. Many jewelers also were goldsmiths. The Sunar caste is one of the oldest communities in goldsmithing in India, whose superb gold artworks were displayed at The Great Exhibition of 1851 in London. In India, 'Vishwakarma', 'Daivadnya Brahmins', 'Kshatriya Sunar' are the goldsmith castes. The printmaking technique of engraving developed among goldsmiths in Germany around 1430, who had long used the technique on their metal pieces.

Gold, being the most malleable metal of all, offers unique opportunities for the worker. In today's world a wide variety of other metals, especially platinum alloys, also may be used frequently. 24 karat is pure gold and historically, was known as fine gold. Because it is so soft, however, 24 karat gold is rarely used. It is usually alloyed to make it stronger and to create different colors. Depending on the metals used to create the alloy, the color can change. This alloyed gold is then stamped with the 725 mark, representing the percentage of gold present in the alloy for commercially used gold. The majority of the jewellery is made with this alloy, while a smaller part uses lower gold-density alloys to keep jewel cheaper. The gold may be cast into some item then, usually with the lost wax casting process, or it may be used to fabricate the work directly in metal. In the latter case, the goldsmith will use a variety of tools and machinery, including the rolling mill, the drawplate, and perhaps, swage blocks and other forming tools to make the metal into shapes needed to build the intended piece. Then parts are fabricated through a wide variety of processes and assembled by soldering. It is a testament to the history and evolution of the trade that those skills have reached an extremely high level of attainment and skill over time.

Only wealthy medieval European lords could afford to build castles or equivalent structures on their lands; many of them only owned one village, or even only part of a village. This was an insufficient base to afford castles. Such lords usually lived in \"knight's houses\", which were fairly simple houses, scarcely bigger than those of their tenants. In some parts of the Holy Roman Empire of the German Nation, inheritance law required that the estate be divided among all successors. These successors, each of whose individual inheritance was too small to build a castle of his own, could build a castle together, where each owned one separate part for housing and all of them together shared the defensive fortification. In the case of Eltz, the family comprised three branches and the existing castle was enhanced with three separate complexes of buildings. The main part of the castle consists of the family portions.

In the years 1331–1336, there occurred the only serious military conflicts that the castle experienced. During the Eltz Feud, the lords of Eltzer, together with other free imperial knights, opposed the territorial policy of the Archbishop and Elector Balduin von Trier. The Eltz Castle was put under siege and possible capture and was bombarded with catapults by the Archbishop of the Diocese of Trier. A small siege castle, Trutzeltz Castle, was built on a rocky outcrop on the hillside above the castle, which can still be seen today as a few ruined walls outside of the northern side of the castle. The siege lasted for two years, but ended only when the free imperial knights had given up their imperial freedom. Balduin reinstated Johann again to the burgrave, but only as his subjects and no longer as a free knight. In 1472 the Rübenach house, built in the Late Gothic style, was completed. Remarkable are the Rübenach Lower Hall, a living room, and the Rübenach bedchamber with its opulently decorated walls. Started in 1470 by Philipp zu Eltz, the 10-story Greater Rodendorf House takes its name from the family's land holding in Lorraine. The oldest part is the flag hall with its late Gothic vaulted ceiling, which was probably originally a chapel. Construction was completed around 1520. The (so-called) Little Rodendorf house was finished in 1540, also in Late Gothic style. It contains the vaulted \"banner-room\". The Kempenich house replaced the original hall in 1615. Every room of this part of the castle could be heated; in contrast, other castles might only have one or two heated rooms. In the Palatinate War of Succession from 1688 to 1689, most of the early Rhenish castles were destroyed. Since Hans Anton was a senior officer in the French army to Eltz Üttingen, he was able to protect the castle Eltz from destruction. Count Hugo Philipp zu Eltz was thought to have fled during the French rule on the Rhine from 1794 to 1815. The French confiscated his possessions on the Rhine and nearby Trier which included Eltz castle, as well as the associated goods which were held at the French headquarters in Koblenz. In 1797, when Count Hugo Philipp later turned out to have remained hidden in Mainz, he came back to the reclaim of his lands, goods and wealth. In 1815 he became the sole owner of the castle through the purchase of the Rübenacher house and the landed property of the barons of Eltz-Rübenach.

The conquest by the Romans in 16–14 BC had a dramatic impact on the whole region. Even today many traces of the 400-year Roman occupation can be found: for example, the famous 'Römerschatz' (Roman treasure) which was excavated in 1950 and which is shown in the Gäubodenmuseum. \"Sorviodurum\", as the Romans called it, was an important military support base. After the fall of the Roman Empire Straubing became a centre of settlement of the Bavarii, mostly around St. Peter's Church (built in the 9th century) between Allachbach and Danube. According to the customs of the Bavarii the settlement was named after their leader \"Strupinga\", which later evolved into the name Straubing. In 1218 a new part of the city (called 'new town') was founded by Duke Ludwig I Wittelsbach of Bavaria. Straubing became the capital of the Duchy of Bavaria-Straubing under Duke Wilhelm I when Bavaria was divided among the sons of Louis IV, Holy Roman Emperor in 1349. In 1429 Straubing passed to Ernest, Duke of Bavaria-Munich, who ordered the murder of Agnes Bernauer in Straubing. The grave of Agnes Bernauer cannot be found. But in the graveyard of St. Peter's Church is a chapel built by Duke Ernest. In 1633, during the Thirty Years' War, the Swedish army successfully besieged the city. Nowadays, this new town is the centre of Straubing with many shops, offices, restaurants and a pedestrian area. Most buildings there still have medieval style. The nightlife of Straubing, with many pubs and discothèques, is concentrated in this area. The most important buildings are the beautiful Gothic cathedral-like Basilica of St. Jacob, the Romanesque St. Peter's Church, the Carmelite monastery with its Baroque church and library, St. Vitus's, where you can find a life-size personification of \"state and church\" joined in holy matrimony. Between 1933 and 1945 most of the members of the then small Jewish community of Straubing were murdered or forced to emigrate. In 2006, Straubing had a lively Jewish community with around 950 members. During a rally in June 1940, when Straubing and Bogen held its Kriegskreistag, some 20,000 people gathered at the \"Großdeutschlandplatz\". Among the speakers were Gauleiter Wächtler and \"Gauamtsleiter\" Erbersdobler. In July 1940, the \"Donau-Zeitung\" reported that the Straubing \"Kreisleiter\", Anton Putz, had flown toward France and not returned. In 1944 and 1945, Straubing suffered from several American air raids. The local military hospital was destroyed to the extent of 80 percent with a loss of 45 patients. In November 2016 a fire destroyed a greater part of the medieval town hall.

Saulnier's work on metal deflector wedges attached to propeller blades was taken forward by Garros; he eventually had a workable installation fitted to his Morane-Saulnier Type L aircraft.

He traveled to England with him that winter. While there, they visited photographer Cecil Beaton, who was working for the British edition of \"Vogue\". In 1931, Horst began his association with \"Vogue\", publishing his first photograph in the French edition of \"Vogue\" in December of that year. It was a full-page advertisement showing a model in black velvet holding a Klytia scent bottle. His first exhibition took place at La Plume d'Or in Paris in 1932. It was reviewed by Janet Flanner in \"The New Yorker\", and this review, which appeared after the exhibition ended, made Horst instantly prominent.

Riders preferred to operate their vehicles on the smooth pavements instead of the rough roads, but their interactions with pedestrians caused many municipalities worldwide to enact laws prohibiting their use.

She sees her neighbors' furniture stacked in the street, new West German cars for sale, advertisements for Western corporations, and a statue of Lenin being flown away by helicopter. Alex and Ariane take her home and show her a fake newscast explaining East Germany is now accepting refugees from the West following an economic crisis there. At the family dacha Christiane reveals her own secret: Her husband had fled not for a mistress but because his refusal to join the ruling party had made his life and job increasingly difficult, and the plan had been for the rest of the family to join him. Christiane, fearing the government would take her children if things went wrong, decided to stay. Contrary to what she had told her children their father wrote many letters which she hid. As she declares her wish to see her husband one last time to make amends, she relapses and is taken back to hospital. Alex meets his father, Robert, who has remarried, has two children, and lives in West Berlin. He convinces him to see Christiane one last time. Under pressure to reveal the truth about the fall of the East, Alex creates a final fake news segment, persuading a taxi driver (who is or resembles cosmonaut Sigmund Jähn, the first German in space and Alex's childhood hero) to act in the false news report as the new leader of East Germany and to give a speech about opening the borders to the West. However, unbeknownst to Alex, Lara had already recounted the true political developments to Christiane earlier that day. Christiane reacts fondly to her son's effort without revealing her knowledge.

Wasik avoided such problems during the first successful flash mob, which occurred on June 17, 2003 at Macy's department store, by sending participants to preliminary staging areas—in four Manhattan bars—where they received further instructions about the ultimate event and location just before the event began. More than 130 people converged upon the ninth floor rug department of the store, gathering around an expensive rug. Anyone approached by a sales assistant was advised to say that the gatherers lived together in a warehouse on the outskirts of New York, that they were shopping for a \"love rug\", and that they made all their purchase decisions as a group. Subsequently, 200 people flooded the lobby and mezzanine of the Hyatt hotel in synchronized applause for about 15 seconds, and a shoe boutique in SoHo was invaded by participants pretending to be tourists on a bus trip.

In 1973, the story \"Flash Crowd\" by Larry Niven described a concept similar to flash mobs. With the invention of popular and very inexpensive teleportation, an argument at a shopping mall—which happens to be covered by a news crew—quickly swells into a riot. In the story, broadcast coverage attracts the attention of other people, who use the widely available technology of the teleportation booth to swarm first that event—thus intensifying the riot—and then other events as they happen. Commenting on the social impact of such mobs, one character (articulating the police view) says, \"We call them flash crowds, and we watch for them.\" In related short stories, they are named as a prime location for illegal activities (such as pickpocketing and looting) to take place. Lev Grossman suggests that the story title is a source of the term \"flash mob\" Flash mobs began as a form of performance art.

In 1804 the family home was moved to Utzenstorf, a village in the Bernese Emmental. Here young Bitzius grew up, receiving his early education and consorting with the boys of the village, as well as helping his father to cultivate his glebe. In 1812 he went to complete his education at Bern. He was a founding member of the Student Society Zofingia, the second-oldest fraternity in Switzerland (founded in 1819). In 1820 he was received as a pastor. In 1821 he enrolled for a year at the University of Göttingen, but returned home in 1822 to act as his father's assistant. On his father's death (1824) he went in the same capacity to Herzogenbuchsee, and later to Bern (1829). Early in 1831 he went as assistant to the aged pastor of the village of Lützelflüh, in the Lower Emmental (between Langnau and Burgdorf), being soon elected his successor (1832) and marrying one of his granddaughters, Henriette Zeender (1833). He spent the rest of his life in Lützelflüh, where he died, leaving three children (the son was a pastor, the two daughters married pastors). During the 1840s, he steadfastly opposed radicalism and secularism and placed a conservative emphasis on piety and ecclesiastical authority. There are lives of Bitzius by C.

It purported to be the life of Jeremias Gotthelf, narrated by himself, and this name was later adopted by the author as his pen name. It sketches the development of a poor country orphan boy, but is not an autobiography. It is a living picture of Bernese (or, strictly speaking, Emmental) village life, true to nature, and not attempting to gloss over its defects and failings. It is written (like the rest of his works) in German, but contains expressions from the Bernese dialect of the Emmental, though Bitzius was not (like Auerbach) a peasant by birth, but belonged to the educated classes, so that he reproduces what he had seen and learnt, and not what he had himself personally experienced. The book was a great success, as it was a picture of real life, and not of fancifully beribboned eighteenth-century villagers. Henceforth Bitzius was a prolific writer, and in the last 18 years of his life became one of the important novelists not only of Switzerland but of the German language in general. His best known work is without doubt the short novel \"The Black Spider\" (\"Die schwarze Spinne\"), a semi-allegorical tale of the plague in form of the titular monster that devastates a Swiss valley community; first as a result of a pact with the devil born out of need and a second time due to the moral decay that releases the monster from its prison again.

After the rebellion was crushed in AD 9, the province of Illyricum was dissolved, and its lands were divided between the new provinces of Pannonia in the north and Dalmatia in the south. The date of the division is unknown, most certainly after AD 20 but before AD 50. The proximity of dangerous barbarian tribes (Quadi, Marcomanni) necessitated the presence of a large number of troops (seven legions in later times), and numerous fortresses were built on the bank of the Danube. Some time between the years 102 and 107, between the first and second Dacian wars, Trajan divided the province into Pannonia Superior (western part with the capital Carnuntum), and Pannonia Inferior (eastern part with the capitals in Aquincum and Sirmium). According to Ptolemy, these divisions were separated by a line drawn from Arrabona in the north to Servitium in the south; later, the boundary was placed further east. The whole country was sometimes called the Pannonias (Pannoniae). Pannonia Superior was under the consular legate, who had formerly administered the single province, and had three legions under his control. Pannonia Inferior was at first under a praetorian legate with a single legion as the garrison; after Marcus Aurelius, it was under a consular legate, but still with only one legion. The frontier on the Danube was protected by the establishment of the two colonies Aelia Mursia and Aelia Aquincum by Hadrian. Under Diocletian, a fourfold division of the country was made: Diocletian also moved parts of today's Slovenia out of Pannonia and incorporated them in Noricum. In 324 AD, Constantine I enlarged the borders of Roman Pannonia to the east, annexing the plains of what is now eastern Hungary, northern Serbia and western Romania up to the limes that he created: the Devil's Dykes. In the 4th-5th century, one of the dioceses of the Roman Empire was known as the Diocese of Pannonia.

In English works he often appears as \"Hugh de Payns\", in Italian sometimes as \"Ugo de' Pagani'.", "section_level": 1}, {"title": "Origin and early life.", "content": "There is no known early biography of Hugues de Payens in existence, nor do later writers cite such a biography. None of the sources on his later career give details of his early life. Information is therefore scanty and uncertain; embellishments depend partly on documents that may not refer to the same individual, partly on histories written decades or even centuries after his death. The earliest source that details a geographical origin for the later Grand Master is the Old French translation of William of Tyre's \"History of Events Beyond the Sea\". The Latin text calls him simply \"Hugo de Paganis\", but the French translation, dated to c. 1200, describes him as \"Hues de Paiens delez Troies\" (\"Hugh of Payens near Troyes\"), a reference to the village of Payns, about 10 km from Troyes, in Champagne (eastern France). In early documents of that region \"Hugo de Pedano, Montiniaci dominus\" is mentioned as a witness to a donation by Count Hugh of Champagne in a document of 1085–90, indicating that the man was at least sixteen by this date—a legal adult and thus able to bear witness to legal documents—and so born no later than 1070. The same name appears on a number of other charters up to 1113 also relating to Count Hugh of Champagne, suggesting that \"Hugo de Pedano\" or \"Hugo dominus de Peanz\" was a member of the Count's court. By the year 1113 he was married to Elizabeth de Chappes, who bore him at least one child, Thibaud, later abbot of Abbaye de la Colombe|la Colombe at Sens. The documents span Hugues' lifetime and the disposition of his property after his death. The one belated statement that the founder of the Knights Templars came from \"Payns near Troyes\" has some circumstantial confirmation. Bernard of Clairvaux, who favoured the Order and helped to compose its \"Latin Rule\", also had the support of Hugh of Champagne. The \"Latin Rule\" of the Order was confirmed at the Council of Troyes in 1129. A Templar commandery was eventually built at Payns. Some scholars have however looked for Hugues' origins elsewhere. There was an early claim that he came from the Vivarais (the district of Viviers in the modern \"département\" of Ardèche). Hugues has also been identified with Hug de Pinós, third son of Galceran I, lord of Pinós in Catalonia; however, Galceran married only in 1090, far too late a date for him to be the father of the founder of the Knights Templars. There is also a claim that Hugues de Payens or \"Ugo de' Pagani\" came from Nocera de' Pagani in Campania, southern Italy. Reference to Nocera as his birthplace is found at least as early as Baedeker's \"Southern Italy\" (1869) and is also found in the Old Catholic Encyclopedia. Two more recent writers say that the theory is supported by a letter that Hugues wrote from Palestine in 1103, in which he talked of writing to \"my father in Nocera\" to tell him of the death of his cousin Alessandro.", "section_level": 1}, {"title": "The foundation of the Order.", "content": "Hugh, Count of Champagne made a pilgrimage to the Holy Land in 1104–07 and visited Jerusalem for a second time in 1114–16. It is probable that he was accompanied by Hugues de Payens, who remained there after the Count returned to France as there is a charter with \"Hugonis de Peans\" in the witness list from Jerusalem in 1120 and again in 1123. In 1125 his name appears again as a witness to a donation, this time accompanied by the title \"magister militum Templi\" (\"Master of the Knights of the Temple\"). He most likely obtained approval for the Order from King Baldwin II of Jerusalem and Warmund, Patriarch of Jerusalem at the Council of Nablus in 1120. One early chronicler, Simon de St. Bertin, implies that the Knights Templar originated earlier, before the death of Godfrey of Bouillon in 1100: \"While he [Godfrey] was reigning magnificently, some had decided not to return to the shadows of the world after suffering such dangers for God's sake. On the advice of the princes of God's army they vowed themselves to God's Temple under this rule: they would renounce the world, give up personal goods, free themselves to pursue purity, and lead a communal life wearing a poor habit, only using arms to defend the land against the attacks of the insurgent pagans when necessity demanded.\" Later chroniclers write that Hugues de Payens approached King Baldwin II of Jerusalem (whose reign began in 1118) with eight knights, two of whom were brothers and all of whom were his relatives by either blood or marriage, in order to form the Order of the Knights Templar. The other knights were Godfrey de Saint-Omer, Payen de Montdidier, Archambaud de St. Agnan, André de Montbard, Geoffrey Bison, and two men recorded only by the names of Rossal and Gondamer. Baldwin approved the foundation of the Order and entrusted the Temple of Jerusalem to its care. Count Hugh of Champagne himself joined the Knights Templar on his third visit to the Holy Land in 1125. As Grand Master, Hugues de Payens led the Order for almost twenty years until his death, helping to establish the Order's foundations as an important and influential military and financial institution. On his visit to England and Scotland in 1128, he raised men and money for the Order, and also founded their first House in London and another near Edinburgh at Balantrodoch, now known as Temple, Midlothian. The \"Latin Rule\" laying down the way of life of the Order, attributed to Hugues de Payens and Bernard of Clairvaux, was confirmed in 1129 at the Council of Troyes over which Pope Honorius II presided. Hugues de Payens died, apparently on Bornholm, in 1136. He had lived on the island in his older days and has also used hammerhus to meetings, with the templegroup. The circumstances and date of his death are not recorded in any chronicle, though the Templars commemorated him every year on 24 May, and it's presumed he died of old age.

In 1953, he founded the period-instrument ensemble Concentus Musicus Wien with his wife, Alice Hoffelner, whom he married that year. The Concentus Musicus Wien was dedicated to performances on period instruments, and by the 1970s his work with it had made him quite well known. He played the viola da gamba at this time, as well as the cello. For the Telefunken (later Teldec) label, Harnoncourt recorded a wide variety of the Baroque repertoire, beginning with the viol music of Henry Purcell, and extending to include works like Bach's \"The Musical Offering\", Monteverdi's \"L'incoronazione di Poppea\", and Rameau's \"Castor et Pollux\". One of his final recordings with the Concentus Musicus Wien was of Beethoven's Symphonies Nos. 4 and 5. One reason that Harnoncourt left the Vienna Symphony was to become a conductor. He made his conducting debut at La Scala, Milan, in 1970, leading a production of Monteverdi's \"Il ritorno d'Ulisse in patria\". In 1971, Harnoncourt started a joint project with conductor Gustav Leonhardt to record all of J. S. Bach's cantatas. The Teldec Bach cantata project was eventually completed in 1990 and was the only cantata cycle to use an all-male choir and soloist roster, with the exception of cantatas nos. 51 and 199, which were intended for a female soprano voice. He also made the first recordings in historically informed performance of Bach's Mass in B minor (1968) and \"St Matthew Passion\" (1970). In 2001 a critically acclaimed and Grammy Award winning recording of the \"St Matthew Passion\" with the Arnold Schoenberg Choir was released, which included the entire score of the piece in Bach's own hand on a CD-ROM. This was his third recording of the work. Harnoncourt later performed with many other orchestras that played on modern instruments, but still with an eye on historical authenticity in terms of tempi and dynamics, among other things. He also expanded his repertoire, continuing to play the baroque works, but also championing the Viennese operetta repertoire. He made a benchmark recording of Beethoven's symphonies with the Chamber Orchestra of Europe (COE), and recorded Beethoven's piano concertos with Pierre-Laurent Aimard and the COE. Harnoncourt was also a guest conductor of the Vienna Philharmonic and made several recordings with the orchestra. Between 1987 and 1991, he conducted four new productions of Mozart operas at the Vienna State Opera (1987–91: \"Idomeneo\"; 1988–90: \"Die Zauberflöte\"; 1989: \"Die Entführung aus dem Serail\"; 1989–91: \"Così fan tutte\"). He directed the Vienna Philharmonic's New Year's Day concerts in 2001 and 2003. In 1992, Harnoncourt debuted at the Salzburg Festival conducting a concert with the Chamber Orchestra of Europe. In the following years, he led several concerts with the Chamber Orchestra of Europe, the Vienna Philharmonic and the Concentus Musicus. Harnoncourt also served as the conductor for major opera productions of the Festival: \"L'incoronazione di Poppea\" (1993), Mozart's \"Le nozze di Figaro\" (1995 and 2006), \"Don Giovanni\" (2002, marking also Anna Netrebko's international breakthrough as Donna Anna, and 2003) and \"La clemenza di Tito\" (2003 and 2006), and Purcell's \"King Arthur\" (2004). In 2012, Harnoncourt conducted a new production of \"Die Zauberflöte\" staged by Jens-Daniel Herzog. Harnoncourt made his guest-conducting debut with the Concertgebouw Orchestra, Amsterdam, in 1975.

The early camping equipment was very heavy, so it was convenient to transport it by boat or to use craft that converted into tents. Although Thomas Hiram Holding is often seen as the father of modern camping in the UK, he was responsible for popularising a different type of camping in the early twentieth century. He experienced the activity in the wild from his youth, when he had spent much time with his parents traveling across the American prairies. Later he embarked on a cycling and camping tour with some friends across Ireland. His book on his Ireland experience, \"Cycle and Camp in Connemara\" led to the formation of the first camping group in 1901, the Association of Cycle Campers, later to become the Camping and Caravanning Club. He wrote \"The Campers Handbook\" in 1908, so that he could share his enthusiasm for the great outdoors with the world. Possibly the first commercial camping ground in the world was Cunningham's camp, near Douglas, Isle of Man, which opened in 1894. In 1906 the Association of Cycle Campers opened its first own camping site, in Weybridge. By that time the organization had several hundred members. In 1910 the Association was merged into the National Camping Club. Although WW1 was responsible for a certain hiatus in camping activity, the association received a new lease of life after the war when Sir Robert Baden-Powell (founder of the Boy Scouts movement) became its president.

However, an archaeological expedition from the Institute of History of the National Academy of Sciences of Belarus suggests that Polotsk existed in the first half of the 9th century. The first known prince of Polotsk was Rogvolod (ruled 945–978). He had two sons and a daughter named Rogneda. Rogvolod promised Rogneda to the prince of Kiev, Yaropolk, as a wife. But Yaropolk's brother, Vladimir, had attacked Polotsk before Yaropolk came. He killed Rogvolod, his wife and sons, and married Rogneda. Vladimir and Rogneda had five children and the eldest of them, Izyaslav, became Prince of Polotsk (ruled 989-1001). Between the 10th and 12th centuries, the Principality of Polotsk emerged as the dominant center of power in what is now Belarusian territory, with a lesser role played by the Principality of Turov to the south. It repeatedly asserted its sovereignty in relation to other centers of Kievan Rus, becoming a political capital, the episcopal see and the controller of vassal territories among Balts in the west. Its most powerful ruler was Prince Vseslav Bryachislavich, who reigned from 1044 to 1101. A 12th-century inscription commissioned by Vseslav's son Boris may still be seen on a huge boulder installed near the St. Sophia Cathedral. For a full list of the Polotsk rulers, see the list of Belarusian rulers. In 1240, Polotsk became a vassal of the Lithuanian princes. The Grand Duke of Lithuania Vytenis annexed the city by military force in 1307, completing the process which the Lithuanian princes had begun in the 1250s. Polotsk received a charter of autonomy guaranteeing that the grand dukes \"will not introduce new, nor destroy the old\". It was the earliest to be so incorporated into the Grand Duchy of Lithuania. By doing so, the Lithuanians managed to firmly grasp the Dvina trade route in their hands, securing an important element for the surrounding economies. Magdeburg law was adopted in 1498. Polotsk functioned as a capital of the Połock Voivodship of the Polish-Lithuanian Commonwealth until 1772. Captured by the Russian army of Ivan the Terrible in 1563, it was returned to the Grand Duchy of Lithuania just 15 years later. It was again captured by Russia on 17 June 1654, but recaptured by Poland-Lithuania on 30 October 1660 during the Russo-Polish War (1654-67). In 1773, with the First Partition of Poland, Russia seized Polotsk (then Połock) as part of the Russian Partition of the Polish–Lithuanian Commonwealth. Since the Russian Empress Catherine II did not acknowledge the Papal suppression of the Society of Jesus (1773–1814), the Jesuit branches in these lands were not disbanded, and Połock became the European centre of the Order, with a novitiate opening in 1780, and with the arrival of distinguished Jesuits from other parts of Europe who brought with them valuable books and scientific collections. Jesuits continued their pastoral work and upgraded the Jesuit College in Polotsk (opened in 1580 by decree of the Polish king Stefan Batory, with the Jesuit Piotr Skarga (1536-1612) as its first rector) into the Połock Academy (1812–1820), with three faculties (Theology, Languages and Liberal Arts), four libraries, a printing house, a bookshop, a theatre with 3 stages, a science museum, an art gallery and a scientific and literary periodical, and a medical-care centre. The school was also the patron of the college in Petersburg, the mission to Saratów and an expedition to Canton. When in 1820 pressure from the Russian Orthodox Church influenced the Russian Emperor Alexander I to exile the Jesuits and to close the Academy, there were 700 students studying there. The Russian authorities also broke up the Academy's library of 40,000-60,000 volumes, the richest collection of 16th- to 18th-century books - the books went to St. Petersburg, Kiev and other cities, 4000 volumes (along with books from other closed Jesuit schools) going to the St. Petersburg State University Scientific Library. That period of warfare started the gradual decline of the city. After the first partition of Poland (1772), Polotsk became reduced to the status of a small provincial town of the Russian Empire. During the French invasion of Russia in 1812 the area saw two battles, the First Battle of Polotsk (August 1812) and the Second Battle of Polotsk (October 1812). Polotsk came under occupation by the German Empire between 25 February 1918 and 21 November 1918 in World War I, by Poland between 22 September 1919 and 14 May 1920 in the Polish–Soviet War and by Nazi Germany between 16 July 1941 and 4 July 1944 in World War II.

The cathedral had been ruined by the troops of Peter I of Russia. Hence the present baroque building by Johann Christoph Glaubitz dates from the mid-18th century.

During the first dynasty of Babylon, Hammurabi and his governors served as the highest appellate courts of the land. Ancient Roman law employed a complex hierarchy of appellate courts, where some appeals would be heard by the emperor. Additionally, appellate courts have existed in Japan since at least the Kamakura Shogunate (1185–1333 CE). During this time, the Shogunate established \"hikitsuke\", a high appellate court to aid the state in adjudicating lawsuits. Although some scholars argue that \"the right to appeal is itself a substantive liberty interest\", the notion of a right to appeal is a relatively recent advent in common law jurisdictions. In fact, commentators have observed that common law jurisdictions were particularly \"slow to incorporate a right to appeal into either its civil or criminal jurisprudence\". The idea of an appeal from court to court (as distinguished from court directly to the Crown) was unheard of in early English courts. English common law courts eventually developed the writs of error and certiorari as routes to appellate relief, but both types of writs were severely limited in comparison to modern appeals in terms of availability, scope of review, and remedies afforded. For example, writs of error were originally not available as a matter of right and were issued only upon the recommendation of the Attorney General (which was regularly granted in modern times). Certiorari was originally available only for summary offences; in the early 19th century, certiorari became available for indictable offences, but only to obtain relief before judgment. Due to widespread dissatisfaction with writs (resulting in the introduction of at least 28 separate bills in Parliament), England switched over to appeals in civil cases in 1873, and in criminal cases in 1907. The United States first created a system of federal appellate courts in 1789, but a federal right to appeal did not exist in the United States until 1889, when Congress passed the Judiciary Act to permit appeals in capital cases. Two years later, the right to appeals was extended to other criminal cases, and the United States Courts of Appeals were established to review decisions from district courts.

A fundamental premise of many legal systems is that appellate courts review questions of law \"de novo\", but appellate courts do not conduct independent fact-finding. Instead, appellate courts will generally defer to the record established by the trial court, unless some error occurred during the fact-finding process. Many jurisdictions provide a statutory or constitutional right for litigants to appeal adverse decisions. However, most jurisdictions also recognize that this right may be waived. In the United States, for example, litigants may waive the right to appeal, as long as the waiver is \"considered and intelligent\". The appellate process usually begins when an appellate court grants a party's petition for review or petition for certiorari. Unlike trials, appeals are generally presented to a judge, or a panel of judges, rather than a jury. Before making any formal argument, parties will generally submit legal briefs in which the parties present their arguments. Appellate courts may also grant permission for an \"amicus curiae\" to submit a brief in support of a particular party or position. After submitting briefs, parties often have the opportunity to present an oral argument to a judge or panel of judges.

Many complementary currencies use time as a unit of measure, using mutual credit accounting that keeps the balance of money intact. Modern money (and most ancient money too) is essentially a token – an abstraction. Paper currency is perhaps the most common type of physical money today.

Caesar Augustus gave \"coins of every device, including old pieces of the kings and foreign money\" as Saturnalia gifts. Petrarch, who wrote in a letter that he was often approached by vinediggers with old coins asking him to buy or to identify the ruler, is credited as the first Renaissance collector. Petrarch presented a collection of Roman coins to Emperor Charles IV in 1355. The first book on coins was \"De Asse et Partibus\" (1514) by Guillaume Budé. During the early Renaissance ancient coins were collected by European royalty and nobility. Collectors of coins were Pope Boniface VIII, Emperor Maximilian of the Holy Roman Empire, Louis XIV of France, Ferdinand I, Elector Joachim II of Brandenburg who started the Berlin coin cabinet and Henry IV of France to name a few. Numismatics is called the \"Hobby of Kings\", due to its most esteemed founders. Professional societies organised in the 19th century. The Royal Numismatic Society was founded in 1836 and immediately began publishing the journal that became the \"Numismatic Chronicle\". The American Numismatic Society was founded in 1858 and began publishing the \"American Journal of Numismatics\" in 1866. In 1931 the British Academy launched the Sylloge Nummorum Graecorum publishing collections of Ancient Greek coinage. The first volume of Sylloge of Coins of the British Isles was published in 1958. In the 20th century coins gained recognition as archaeological objects, scholars such as Guido Bruck of the Kunsthistorisches Museum in Vienna realised their value in providing a temporal context and the difficulty that curators faced when identifying worn coins using classical literature. After World War II in Germany a project, \"Fundmünzen der Antike\" (Coin finds of the Classical Period) was launched, to register every coin found within Germany. This idea found successors in many countries. In the United States, the US mint established a coin cabinet in 1838 when chief coiner Adam Eckfeldt donated his personal collection. William E. Du Bois’ \"Pledges of History...\" (1846) describes the cabinet. C. Wyllys Betts' \"American colonial history illustrated by contemporary medals\" (1894) set the groundwork for the study of American historical medals.

It is believed that people have been collecting paper money for as long as it has been in use.

The turning point occurred in the 1970s, when notaphily was established as a separate area by collectors. At the same time, some developed countries such as the United States, Germany and France began publishing their respective national catalogues of paper money, which represented major points of reference literature.

Within opera, the lowest demanded note for sopranos is F (from Richard Strauss's \"Die Frau ohne Schatten\"). Often low notes in higher voices will project less, lack timbre, and tend to \"count less\" in roles (although some Verdi, Strauss and Wagner roles call for stronger singing below the staff). However, rarely is a soprano simply unable to sing a low note in a song within a soprano role. Low notes can be reached with a lowered position of the larynx.

A couple of roles have optional Es, as well. In the coloratura repertoire several roles call for E on up to F. In rare cases, some coloratura roles go as high as G or G, such as Mozart's concert aria \"Popoli di Tessaglia!\", or the title role of Jules Massenet's opera \"Esclarmonde\". While not necessarily within the tessitura, a good soprano will be able to sing her top notes full-throated, with timbre and dynamic control.

Inspired by this research and Vogt's work, Johannes Heinrich Schultz became interested in the phenomenon of autosuggestion. He wanted to explore an approach, which would avoid undesirable implications of hypnotherapy (e.g., the passivity of the individual and dependency on the therapist). When he was investigating hallucinations in healthy persons, he found that a majority of the subjects reported having two types of experienced sensation: heaviness in the extremities and feeling of warmth. Schultz wanted to understand whether simply imagining a state of heaviness and warmth in one's limbs could induce a state similar to hypnosis. Based on this idea he developed six basic exercises. Autogenic training was popularized in North America and the English-speaking world by Wolfgang Luthe, who co-authored, with Schultz, a multi-volume tome on autogenic training. In 1963 Luthe discovered the significance of \"autogenic discharges\", paroxysmic phenomena of motor, sensorial, visual and emotional nature related to the traumatic history of the patient, and developed the method of \"autogenic abreaction\".

A network tap is an even more reliable solution than to use a monitoring port, since taps are less likely to drop packets during high traffic load. On wireless LANs, traffic can be captured on one channel at a time, or by using multiple adapters, on several channels simultaneously. On wired broadcast and wireless LANs, to capture unicast traffic between other machines, the network adapter capturing the traffic must be in promiscuous mode. On wireless LANs, even if the adapter is in promiscuous mode, packets not for the service set the adapter is configured for are usually ignored. To see those packets, the adapter must be in monitor mode. No special provisions are required to capture multicast traffic to a multicast group the packet analyzer is already monitoring, or broadcast traffic. When traffic is captured, either the entire contents of packets are recorded, or just the headers are recorded.

Captured information is decoded from raw digital form into a human-readable format that lets users easily review exchanged information.

In 1911 he adapted the 15th century English morality play \"Everyman\" as \"Jedermann\", and Jean Sibelius (amongst others) wrote incidental music for it. The play later became a staple at the Salzburg Festival. During the First World War Hofmannsthal held a government post. He wrote speeches and articles supporting the war effort, and emphasizing the cultural tradition of Austria-Hungary. The end of the war spelled the end of the Habsburg monarchy in Austria; this was a blow from which the patriotic and conservative-minded Hofmannsthal never fully recovered. Nevertheless, the years after the war were very productive ones for Hofmannsthal; he continued with his earlier literary projects, almost without a break. He wrote several new libretti for Richard Strauss operas. In 1920, Hofmannsthal, along with Max Reinhardt, founded the Salzburg Festival.

In this letter Chandos says that he has stopped writing because he has \"lost completely the ability to think or to speak of anything coherently\"; he has given up on the possibility of language to describe the world. This letter reflects the growing distrust of and dissatisfaction with language that so characterizes the Modern era, and Chandos's dissolving personality is not only individual but societal. Growing up the son of a wealthy merchant who was well connected with the major artists of the time, Hofmannsthal was raised in what Carl Schorske refers to as \"the temple of art\". This perfect setting for aesthetic isolation allowed Hofmannsthal the unique perspective of the privileged artist, but also allowed him to see that art had become a flattened documenting of humanity, which took our instincts and desires and framed them for viewing without acquiring any of the living, passionate elements. Because of this realization, Hofmannsthal’s idea of the role of the artist began to take shape as someone who created works that would inspire or inflame the instinct, rather than merely preserving it in a creative form. He also began to think that the artist should not be someone isolated and left to his art, but rather a man of the world, immersed in both politics and art. Hofmannsthal saw in English culture the ideal setting for the artist. This was because the English simultaneously admired Admiral Nelson and John Milton, both war heroes and poets, while still maintaining a solid national identity. \"In [Hofmannsthal’s] view, the division between artist (writer) and man of action (politician, explorer, soldier) does not exist in England. Britain provides her subjects with a common base of energy which functions as equilibrium, a force lacking in fragmented Germany\" (Weiss). This singular and yet pragmatic identity must have appealed to Hofmannsthal to a certain degree due to the large scale fragmentation of Austria at the time, which was in the throes of radical nationalism and anti-Semitism, a nation in which the progressive artist and the progressive politician were growing more different and hostile to each other by the day.", "section_level": 1}, {"title": "Influence.", "content": "The Austrian author Stefan Zweig wrote in his memoirs \"The World of Yesterday\" (1942) on Hofmannsthal's early accomplishments and their influence on Zweig's generation:", "section_level": 1}, {"title": "Selected works.", "content": "Plays Libretti Narrations and fictitious conversations Novel (fragment) Essays, speeches, prose Poetry", "section_level": 1}], "src_summary": "Hugo Laurenz August Hofmann von Hofmannsthal (; 1 February 1874 – 15 July 1929) was an Austrian prodigy, a novelist, librettist, poet, dramatist, narrator, and essayist.", "tgt_summary": null, "id": 4971484} {"src_title": "Class (set theory)", "tgt_title": null, "src_document": [{"title": "Examples.", "content": "The collection of all algebraic structures of a given type will usually be a proper class.

For example, one can reduce the formula formula_1 to formula_2. Semantically, in a metalanguage, the classes can be described as equivalence classes of logical formulas: If formula_3 is a structure interpreting ZF, then the object language \"class-builder expression\" formula_4 is interpreted in formula_3 by the collection of all the elements from the domain of formula_3 on which formula_7 holds; thus, the class can be described as the set of all predicates equivalent to formula_8 (which includes formula_8 itself). In particular, one can identify the \"class of all sets\" with the set of all predicates equivalent to formula_10 Because classes do not have any formal status in the theory of ZF, the axioms of ZF do not immediately apply to classes. However, if an inaccessible cardinal formula_11 is assumed, then the sets of smaller rank form a model of ZF (a Grothendieck universe), and its subsets can be thought of as \"classes\". In ZF, the concept of a function can also be generalised to classes. A class function is not a function in the usual sense, since it is not a set; it is rather a formula formula_12 with the property that for any set formula_13 there is no more than one set formula_14 such that the pair formula_15 satisfies formula_16 For example, the class function mapping each set to its successor may be expressed as the formula formula_17 The fact that the ordered pair formula_15 satisfies formula_19 may be expressed with the shorthand notation formula_20 Another approach is taken by the von Neumann–Bernays–Gödel axioms (NBG); classes are the basic objects in this theory, and a set is then defined to be a class that is an element of some other class. However, the class existence axioms of NBG are restricted so that they only quantify over sets, rather than over all classes. This causes NBG to be a conservative extension of ZF. Morse–Kelley set theory admits proper classes as basic objects, like NBG, but also allows quantification over all proper classes in its class existence axioms. This causes MK to be strictly stronger than both NBG and ZF. In other set theories, such as New Foundations or the theory of semisets, the concept of \"proper class\" still makes sense (not all classes are sets) but the criterion of sethood is not closed under subsets.

Consequently, an individual ruling several states held multiple votes; similarly, multiple individuals ruling parts of the same state shared a single vote. These rules were not formalized until 1582; prior to this time, when multiple individuals inherited parts of the same state, they sometimes received a vote each. Votes were either individual or collective. Princes and senior clerics generally held individual votes (but such votes, as noted above, were sometimes shared). Prelates (abbots and priors) without individual votes were classified into two benches—the Bench of the Rhine and the Bench of Swabia — each of which enjoyed a collective vote. Similarly, Counts were grouped into four comital benches with a collective vote each — the Upper Rhenish Bench of Wetterau, the Swabian Bench, the Franconian Bench and the Westphalian Bench.

The Byzantine Emperor would typically protect the Eastern Church and manage its administration by presiding over Ecumenical Councils and appointing Patriarchs and setting territorial boundaries for their jurisdiction. The Emperor exercised a strong control over the ecclesiastical hierarchy, and the Patriarch of Constantinople could not hold office if he did not have the Emperor's approval. Such Emperors as Basiliscus, Zeno, Justinian I, Heraclius, and Constans II published several strictly ecclesiastical edicts either on their own without the mediation of church councils, or they exercised their own political influence on the councils to issue the edicts. According to Metropolitan Kallistos Ware, the historical reality of caesaropapism stems from the confusion of the Byzantine Empire with the Kingdom of God and the zeal of the Byzantines \"to establish here on earth a living icon of God's government in heaven.\" However, Caesaropapism \"never became an accepted principle in Byzantium.\" Several Eastern churchmen such as John Chrysostom, Patriarch of Constantinople and Athanasius, Patriarch of Alexandria, strongly opposed imperial control over the Church, as did Western theologians like Hilary of Poitiers and Hosius, Bishop of Córdoba. Saints, such as Maximus the Confessor, resisted the imperial power as a consequence of their witness to orthodoxy. In addition, at several occasions imperial decrees had to be withdrawn as the people of the Church, both lay people, monks and priests, refused to accept inventions at variance with the Church's customs and beliefs. These events show that power over the Church really was in the hands of the Church itself – not solely with the emperor. Caesaropapism was most notorious in the Tsardom of Russia when Ivan IV the Terrible assumed the title Czar in 1547 and subordinated the Russian Orthodox Church to the state. This level of caesaropapism far exceeded that of the Byzantine Empire and was taken to a new level in 1721, when Peter the Great replaced the patriarchate with a Holy Synod, making the church a department of his government.

On contact of liquid with a surface, adhesion forces result in wetting of the surface. Either complete or incomplete wetting may occur depending on the structure of the surface and the fluid tension of the droplet. The cause of self-cleaning properties is the hydrophobic water-repellent double structure of the surface. This enables the contact area and the adhesion force between surface and droplet to be significantly reduced, resulting in a self-cleaning process. This hierarchical double structure is formed out of a characteristic epidermis (its outermost layer called the cuticle) and the covering waxes. The epidermis of the lotus plant possesses papillae 10 μm to 20 μm in height and 10 μm to 15 μm in width on which the so-called epicuticular waxes are imposed. These superimposed waxes are hydrophobic and form the second layer of the double structure. This system regenerates. This biochemical property is responsible for the functioning of the water repellency of the surface. The hydrophobicity of a surface can be measured by its contact angle. The higher the contact angle the higher the hydrophobicity of a surface. Surfaces with a contact angle < 90° are referred to as hydrophilic and those with an angle >90° as hydrophobic. Some plants show contact angles up to 160° and are called ultrahydrophobic, meaning that only 2–3% of the surface of a droplet (of typical size) is in contact. Plants with a double structured surface like the lotus can reach a contact angle of 170°, whereby the droplet's contact area is only 0.6%. All this leads to a self-cleaning effect. Dirt particles with an extremely reduced contact area are picked up by water droplets and are thus easily cleaned off the surface. If a water droplet rolls across such a contaminated surface the adhesion between the dirt particle, irrespective of its chemistry, and the droplet is higher than between the particle and the surface. This cleaning effect has been demonstrated on common materials such as stainless steel when a superhydrophobic surface is produced. As this self-cleaning effect is based on the high surface tension of water it does not work with organic solvents. Therefore, the hydrophobicity of a surface is no protection against graffiti. This effect is of a great importance for plants as a protection against pathogens like fungi or algae growth, and also for animals like butterflies, dragonflies and other insects not able to cleanse all their body parts. Another positive effect of self-cleaning is the prevention of contamination of the area of a plant surface exposed to light resulting in reduced photosynthesis.", "section_level": 1}, {"title": "Technical application.", "content": "When it was discovered that the self-cleaning qualities of ultrahydrophobic surfaces come from physical-chemical properties at the microscopic to nanoscopic scale rather than from the specific chemical properties of the leaf surface, the possibility arose of using this effect in manmade surfaces, by mimicking nature in a general way rather than a specific one. Some nanotechnologists have developed treatments, coatings, paints, roof tiles, fabrics and other surfaces that can stay dry and clean themselves by replicating in a technical manner the self-cleaning properties of plants, such as the lotus plant. This can usually be achieved using special fluorochemical or silicone treatments on structured surfaces or with compositions containing micro-scale particulates. In addition to chemical surface treatments, which can be removed over time, metals have been sculpted with femtosecond pulse lasers to produce the lotus effect. The materials are uniformly black at any angle, which combined with the self-cleaning properties might produce very low maintenance solar thermal energy collectors, while the high durability of the metals could be used for self-cleaning latrines to reduce disease transmission. Further applications have been marketed, such as self-cleaning glasses installed in the sensors of traffic control units on German autobahns developed by a cooperation partner (Ferro GmbH). The Swiss companies HeiQ and Schoeller Textil have developed stain-resistant textiles under the brand names \"HeiQ Eco Dry\" and \"nanosphere\" respectively. In October 2005, tests of the Hohenstein Research Institute showed that clothes treated with NanoSphere technology allowed tomato sauce, coffee and red wine to be easily washed away even after a few washes. Another possible application is thus with self-cleaning awnings, tarpaulins and sails, which otherwise quickly become dirty and difficult to clean. Superhydrophobic coatings applied to microwave antennas can significantly reduce rain fade and the buildup of ice and snow. \"Easy to clean\" products in ads are often mistaken in the name of the self-cleaning properties of hydrophobic or ultrahydrophobic surfaces. Patterned ultrahydrophobic surfaces also show promise for \"lab-on-a-chip\" microfluidic devices and can greatly improve surface-based bioanalysis. Superhydrophobic or hydrophobic properties have been used in dew harvesting, or the funneling of water to a basin for use in irrigation.

His stepmother was Empress Justina and his paternal half siblings were Valentinian II, Galla and Justa. Gratian was educated by Ausonius who had praised his pupil for his tolerance. On 24 August 367 he received from his father the title of \"Augustus\". When his father died on 17 November 375, Gratian began his actual reign at the age of sixteen. Six days later, Gratian's half brother Valentinian II, Valentinian's four-year old son by his second wife Justina, was also proclaimed Emperor by troops in Pannonia, impelled by the generals Aequitius and Maximinus, two of Valentinian's more unscrupulous ministers. Gratian prudently acquiesced in their choice; reserving for himself the administration of the Gallic provinces, to command the forces responsible for the frontier, while handing over the peaceful Italy, Illyricum and Africa to Valentinian and his mother, who fixed their residence at Mediolanum. The division, however, was merely nominal, and the real authority even in those provinces remained in the hands of Gratian. Gratian, with the aid of his capable generals Mallobaudes, a king of the Franks, and Naniemus, completely defeated the Lentienses, the southernmost branch of the Alamanni, in May 378 at the Battle of Argentovaria. Next, Gratian personally led a campaign across the Upper Rhine into the territory of the Lentienses. After initial trouble facing the Lentienses on high ground, Gratian blockaded the enemy instead and received their surrender. The Lentienses were forced to supply young men to be levied into the Roman army, while the remainder were allowed to return home. Later that year, Gratian's uncle Valens met his death in the Battle of Adrianople against a coalition of hostile Gothic and Hunnic tribes who had rebelled after being settled in Thrace by the eastern emperor. Valens refused to wait for Gratian, who had promised to march to his aid as soon as the Alemanni threat was contained; as a result, two-thirds of Valens men, to the number of 40,000 dead, fell in the battle along with the emperor and some of his top staff. By the time Gratian arrived in the east, the Gothic war had spiraled out of control; the provinces south of the Danube were daily being devastated by barbarians, and Roman authority as well as military prestige was all but annihilated. Hearing that the Germans were planning a new invasion in Gaul now that Gratian had departed from the province, and convinced that one emperor alone was incapable of repelling the inundation of foes on several different fronts, Gratian appointed the Spaniard Theodosius I Augustus on 19 January 379 to govern the east. During the ensuing four years Theodosius would take advantage of the internal discord and disorder of the Goths to destroy the more intractable of the barbarians and settle the rest by a peaceful treaty in the provinces of Thrace and Asia Minor. For some years Gratian governed the Empire with energy and success, earning the esteem of the army and people by his personal courage and justice, but at length, being deprived by death of some of his abler counselors, the promising young emperor neglected public affairs, and occupied himself chiefly with the hunting. He alienated the army and German auxiliaries by his favoritism towards his Frankish general Merobaudes and a body of Scythian archers whom he made his body-guard and companions in the hunt. On other side his tutor Ausonius which has worked toward religious tolerance, has lost influence with time as bishop Ambrose' influence over Gratian grew. This has resulted with Roman Senate protests and fall of emperor popularity.

Propionic acid displays the general properties of carboxylic acids: it can form amide, ester, anhydride, and chloride derivatives. It undergoes the Hell–Volhard–Zelinsky reaction that involves α-halogenation of a carboxylic acid with bromine, catalysed by phosphorus tribromide, in this case to form 2-bromopropanoic acid, CHCHBrCOOH. This product has been used to prepare a racemic mixture of alanine by ammonolysis.", "section_level": 1}, {"title": "Production.", "content": "In industry, propionic acid is mainly produced by the hydrocarboxylation of ethylene using nickel carbonyl as the catalyst: It is also produced by the aerobic oxidation of propionaldehyde. In the presence of cobalt or manganese salts (manganese propionate is most commonly used), this reaction proceeds rapidly at temperatures as mild as 40–50 °C: Large amounts of propionic acid were once produced as a byproduct of acetic acid manufacture. At the current time, the world's largest producer of propionic acid is BASF, with approximately 150 kt/a production capacity. Propionic acid is produced biologically as its coenzyme A ester, propionyl-CoA, from the metabolic breakdown of fatty acids containing odd numbers of carbon atoms, and also from the breakdown of some amino acids. Bacteria of the genus \"Propionibacterium\" produce propionic acid as the end-product of their anaerobic metabolism. This class of bacteria is commonly found in the stomachs of ruminants and the sweat glands of humans, and their activity is partially responsible for the odor of Emmental cheese, American \"Swiss cheese\" and sweat. Biotechnological production of propionic acid is mainly studied by the use of \"Propionibacterium\" strains. However, production of propionic acid by \"Propionibacteria\" is facing challenges such as severe inhibition of end-products during cell growth and the formation of by-products (acetic acid and succinic acid). One approach to improve productivity and yield during fermentation is through the use of cell immobilization techniques, which also promotes easy recovery, reuse of the cell biomass and enhances microorganisms’ stress tolerance. In 2018, 3D printing technology was used for the first time to create a matrix for cell immobilization in fermentation. Propionic acid production by \"Propionibacterium acidipropionici\" immobilized on 3D-printed nylon beads was chosen as a model study. It was shown that those 3D-printed beads were capable to promote high density cell attachment and propionic acid production, which could be adapted to other fermentation bioprocesses.

The antibiotic Monensin is added to cattle feed to favor propionibacteria over acetic acid producers in the rumen; this produces less carbon dioxide and feed conversion is better. This application accounts for about half of the world production of propionic acid. Another major application is as a preservative in baked goods, which use the sodium and calcium salts. As a food additive, it is approved for use in the EU, USA, Australia and New Zealand. Propionic acid is also useful as an intermediate in the production of other chemicals, especially polymers. Cellulose-acetate-propionate is a useful thermoplastic. Vinyl propionate is also used. In more specialized applications, it is also used to make pesticides and pharmaceuticals. The esters of propionic acid have fruit-like odors and are sometimes used as solvents or artificial flavorings.

A vitamin B-dependent enzyme catalyzes rearrangement of -methylmalonyl-CoA to succinyl-CoA, which is an intermediate of the citric acid cycle and can be readily incorporated there. In propionic acidemia, a rare inherited genetic disorder, propionate acts as a metabolic toxin in liver cells by accumulating in mitochondria as propionyl-CoA and its derivative, methylcitrate, two tricarboxylic acid cycle inhibitors. Propanoate is metabolized oxidatively by glia, which suggests astrocytic vulnerability in propionic acidemia when intramitochondrial propionyl-CoA may accumulate. Propionic acidemia may alter both neuronal and glial gene expression by affecting histone acetylation.

Sometime before 1728, Canaletto began his association with Smith, an English businessman and collector living in Venice who was appointed British Consul in Venice in 1744. Smith later became the artist's principal agent and patron, acquiring nearly fifty paintings, one hundred fifty drawings, and fifteen rare etchings from Canaletto, the largest and finest single group of the artist's works, which he sold to King George III in 1763. In the 1740s Canaletto's market was disrupted when the War of the Austrian Succession led to a reduction in the number of British visitors to Venice. Smith also arranged for the publication of a series of etchings of \"capricci\" (or architectural phantasies) (\"capriccio\" Italian for fancy) in his \"vedute ideale\", but the returns were not high enough, and in 1746 Canaletto moved to London, to be closer to his market. He remained in England until 1755, producing views of London (including several of the new Westminster Bridge, which was completed during his stay) and of his patrons' houses and castles. These included Northumberland House for Sir Hugh Smithson, Bt., who by marriage later became the 2nd Earl of Northumberland; and Warwick Castle for Lord Brooke, later 1st Earl of Warwick. Smithson was one of the commissioners of Westminster Bridge, and it is \"not impossible\" that he had encouraged Canaletto to come to England and record the beginning of the bridge's life. His 1754 painting of Old Walton Bridge includes an image of Canaletto himself. He was often expected to paint England in the fashion with which he had painted his native city. Canaletto's painting began to suffer from repetitiveness, losing its fluidity, and becoming mechanical to the point that the English art critic George Vertue suggested that the man painting under the name 'Canaletto' was an impostor. This may have been because Canaletto's nephew, Bernardo Bellotto, was also using his uncle's nickname; or more likely because the story had been spread by unscrupulous art dealers who had been passing off copies of Canaletto's own work and were anxious to see him return to Venice. Historian Michael Levey described his work from this period as \"inhibited\". In order to refute this claim the artist, through an advertisement in a newspaper, invited \"any Gentleman\" to inspect his latest painting of St. James's Park at his studio in Silver Street (now Beak Street) off Golden Square; however, his reputation never fully recovered in his lifetime. After his return to Venice, Canaletto was elected to the Venetian Academy in 1763 and appointed prior of the \"Collegio dei Pittori\". He continued to paint until his death in 1768.

They are formed from cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays, and silica. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.0025–0.08 inches). Clays and sediments with smaller grain sizes not visible with the naked eye, including siltstones and shales, are typically called \"argillaceous\" sediments; rocks with larger grain sizes, including breccias and conglomerates, are termed \"rudaceous\" sediments. The formation of sandstone involves two principal stages. First, a layer or layers of sand accumulates as the result of sedimentation, either from water (as in a stream, lake, or sea) or from air (as in a desert). Typically, sedimentation occurs by the sand settling out from suspension; i.e., ceasing to be rolled or bounced along the bottom of a body of water or ground surface (e.g., in a desert or erg). Finally, once it has accumulated, the sand becomes sandstone when it is compacted by the pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces between sand grains. The most common cementing materials are silica and calcium carbonate, which are often derived either from dissolution or from alteration of the sand after it was buried. Colors will usually be tan or yellow (from a blend of the clear quartz with the dark amber feldspar content of the sand). A predominant additional colourant in the southwestern United States is iron oxide, which imparts reddish tints ranging from pink to dark red (terracotta), with additional manganese imparting a purplish hue.

Matrix may also be present in the interstitial spaces between the framework grains. Below is a list of several major groups of sandstones. These groups are divided based on mineralogy and texture. Even though sandstones have very simple compositions which are based on framework grains, geologists have not been able to agree on a specific, right way, to classify sandstones. Sandstone classifications are typically done by point-counting a thin section using a method like the Gazzi-Dickinson Method. The composition of a sandstone can have important information regarding the genesis of the sediment when used with a triangular \"Q\"uartz, \"F\"eldspar, \"L\"ithic fragment (QFL diagrams). Many geologists, however, do not agree on how to separate the triangle parts into the single components so that the framework grains can be plotted. Therefore, there have been many published ways to classify sandstones, all of which are similar in their general format.

Some sandstones are resistant to weathering, yet are easy to work. This makes sandstone a common building and paving material including in asphalt concrete. However, some that have been used in the past, such as the Collyhurst sandstone used in North West England, have been found less resistant, necessitating repair and replacement in older buildings. Because of the hardness of individual grains, uniformity of grain size and friability of their structure, some types of sandstone are excellent materials from which to make grindstones, for sharpening blades and other implements. Non-friable sandstone can be used to make grindstones for grinding grain, e.g., gritstone. A type of pure quartz sandstone, orthoquartzite, with more of 90–95 percent of quartz, has been proposed for nomination to the Global Heritage Stone Resource.

The idea was to have intellectuals discuss the country's problems in order to promote new forms of arts and new cultural institutions. Mao, however, also saw this as the chance to promote socialism. He believed that after discussion it would be apparent that socialist ideology was the dominant ideology over capitalism, even amongst non-communist Chinese, and would thus propel the development and spread of the goals of socialism. The beginning of the Hundred Flowers Movement was marked by a speech titled \"On the Correct Handling of the Contradictions Among the People\", in which Mao displayed open support for the campaign, saying \"Our society cannot back down, it could only progress... criticism of the bureaucracy is pushing the government towards the better.\" The speech, published on February 27, 1957, encouraged people to vent their criticisms as long as they were \"constructive\" (\"among the people\") rather than \"hateful and destructive\" (\"between the enemy and ourselves\"). The name of the movement originated in a poem: \"Let a hundred flowers bloom; let a hundred schools of thought contend\" (, \"Bǎihuā qífàng, bǎijiā zhēngmíng\"). Mao had used this to signal what he had wanted from the intellectuals of the country, for different and competing ideologies to voice their opinions about the issues of the day. He alluded to the Warring States period when numerous schools of thought competed for ideological, not military, supremacy. Historically, Confucianism and Taoism had gained prominence, and socialism would now stand to its test. Historians debate whether Mao's motivations for launching the campaign were genuine.

Premier Zhou Enlai received some of these letters, and once again realized that, although the campaign had gained notable publicity, it was not progressing as had been hoped. Zhou approached Mao about the situation, stating that more encouragement was needed from the central bureaucracy to lead the intellectuals into further discussion. By the spring of 1957, Mao had announced that criticism was \"preferred\" and had begun to mount pressure on those who did not turn in healthy criticism on policy to the Central Government. The reception with intellectuals was immediate, and they began voicing concerns without any taboo. In the period from May 1 to June 7, 1957, millions of letters were pouring into the Premier's Office and other authorities. People spoke out by putting up posters around campuses, rallying in the streets, holding meetings for CPC members, and publishing magazine articles. For example, students at Peking University created a \"Democratic Wall\" on which they criticized the CPC with posters and letters. \"They protested CPC control over intellectuals, the harshness of previous mass campaigns such as that against counter-revolutionaries, the slavish following of Soviet models, the low standards of living in China, the proscription of foreign literature, economic corruption among party cadres, and the fact that 'Party members [enjoyed] many privileges which make them a race apart'\".", "section_level": 2}, {"title": "Effects.", "content": "In July 1957, Mao ordered a halt to the campaign.

Mao's earlier speech, \"On the Correct Handling of the Contradictions Among the People\", was significantly changed and appeared later on as an anti-rightist piece in itself. The campaign made a lasting impact on Mao's ideological perception. Mao, who is known historically to be more ideological and theoretical, less pragmatic and practical, continued to attempt to solidify socialist ideals in future movements, and in the case of the Cultural Revolution, employed more violent means. Another result of the Hundred Flowers Campaign was that it discouraged dissent and made intellectuals reluctant to criticize Mao and his party in the future. The Anti-Rightist Movement, that shortly followed and was possibly caused by the Hundred Flowers Campaign, resulted in the persecution of intellectuals, officials, students, artists and dissidents labeled \"rightists\". The campaign led to a loss of individual rights, especially for any Chinese intellectuals educated in Western centers of learning. The Hundred Flowers Movement was the first of its kind in the history of the People's Republic of China in that the government opened up to ideological criticisms from the general public. Although its true nature has always been questioned by historians, it can be generally concluded that the events that took place alarmed the central communist leadership. The movement also represented a pattern that has emerged from Chinese history wherein free thought is promoted by the government, and then suppressed by it. A similar surge in ideological thought would not occur again until the late 1980s, leading up to the Tiananmen Square protests of 1989. The latter surge, however, did not receive the same amount of government backing and encouragement.

In response to concerns that exposing security flaws in the design of locks could make them more vulnerable to criminals, he said: \"Rogues are very keen in their profession, and know already much more than we can teach them\". There is scant formal literature on the issue of security through obscurity. Books on security engineering cite Kerckhoffs' doctrine from 1883, if they cite anything at all. For example, in a discussion about secrecy and openness in Nuclear Command and Control: [T]he benefits of reducing the likelihood of an accidental war were considered to outweigh the possible benefits of secrecy. This is a modern reincarnation of Kerckhoffs' doctrine, first put forward in the nineteenth century, that the security of a system should depend on its key, not on its design remaining obscure. In the field of legal academia, Peter Swire has written about the trade-off between the notion that \"security through obscurity is an illusion\" and the military notion that \"loose lips sink ships\" as well as how competition affects the incentives to disclose. The principle of security through obscurity was more generally accepted in cryptographic work in the days when essentially all well-informed cryptographers were employed by national intelligence agencies, such as the National Security Agency. Now that cryptographers often work at universities, where researchers publish many or even all of their results, and publicly test others' designs, or in private industry, where results are more often controlled by patents and copyrights than by secrecy, the argument has lost some of its former popularity. An early example was PGP, whose source code is publicly available to anyone. The security technology in some of the best commercial browsers is also considered highly secure despite being open source. There are conflicting stories about the origin of this term. Fans of MIT's Incompatible Timesharing System (ITS) say it was coined in opposition to Multics users down the hall, for whom security was far more an issue than on ITS. Within the ITS culture the term referred, self-mockingly, to the poor coverage of the documentation and obscurity of many commands, and to the attitude that by the time a tourist figured out how to make trouble he'd generally got over the urge to make it, because he felt part of the community. One instance of deliberate security through obscurity on ITS has been noted: the command to allow patching the running ITS system (altmode altmode control-R) echoed as $$^D. Typing Alt Alt Control-D set a flag that would prevent patching the system even if the user later got it right.

In normal conditions, the dew point temperature will not be greater than the air temperature, since relative humidity cannot exceed 100%. In technical terms, the dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same rate at which it evaporates. At temperatures below the dew point, the rate of condensation will be greater than that of evaporation, forming more liquid water. The condensed water is called dew when it forms on a solid surface, or frost if it freezes. In the air, the condensed water is called either fog or a cloud, depending on its altitude when it forms. If the temperature is below the dew point, and no dew or fog forms, the vapor is called supersaturated. This can happen if there are not enough particles in the air to act as condensation nuclei. A high relative humidity implies that the dew point is close to the current air temperature. A relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. When the moisture content remains constant and temperature increases, relative humidity decreases, but the dew point remains constant. General aviation pilots use dew point data to calculate the likelihood of carburetor icing and fog, and to estimate the height of a cumuliform cloud base. Increasing the barometric pressure increases the dew point. This means that, if the pressure increases, the mass of water vapor in the air must be reduced in order to maintain the same dew point. For example, consider New York ( elevation) and Denver ( elevation). Because Denver is at a higher elevation than New York, it will tend to have a lower barometric pressure.

The rate at which perspiration can evaporate depends on how much moisture is in the air and how much moisture the air can hold. If the air is already saturated with moisture, perspiration will not evaporate. The body's thermoregulation will produce perspiration in an effort to keep the body at its normal temperature even when the rate at which it is producing sweat exceeds the evaporation rate, so one can become coated with sweat on humid days even without generating additional body heat (such as by exercising). As the air surrounding one's body is warmed by body heat, it will rise and be replaced with other air. If air is moved away from one's body with a natural breeze or a fan, sweat will evaporate faster, making perspiration more effective at cooling the body. The more unevaporated perspiration, the greater the discomfort. A wet bulb thermometer also uses evaporative cooling, so it provides a good measure for use in evaluating comfort level. Discomfort also exists when the dew point is very low (below around ). The drier air can cause skin to crack and become irritated more easily. It will also dry out the airways. The US Occupational Safety and Health Administration recommends indoor air be maintained at with a 20–60% relative humidity, equivalent to a dew point of. Lower dew points, less than, correlate with lower ambient temperatures and causes the body to require less cooling. A lower dew point can go along with a high temperature only at extremely low relative humidity, allowing for relatively effective cooling. People inhabiting tropical and subtropical climates acclimatize somewhat to higher dew points. Thus, a resident of Singapore or Miami, for example, might have a higher threshold for discomfort than a resident of a temperate climate like London or Chicago. People accustomed to temperate climates often begin to feel uncomfortable when the dew point gets above, while others might find dew points up to comfortable. Most inhabitants of temperate areas will consider dew points above oppressive and tropical-like, while inhabitants of hot and humid areas may not find this uncomfortable.

For example, it is common on some corporate networks to have internal systems trust each other, so that users can log in without a username or password provided they are connecting from another machine on the internal network (and so must already be logged in). By spoofing a connection from a trusted machine, an attacker on the same network may be able to access the target machine without authentication. IP address spoofing is most frequently used in denial-of-service attacks, where the objective is to flood the target with an overwhelming volume of traffic, and the attacker does not care about receiving responses to the attack packets. Packets with spoofed IP addresses are more difficult to filter since each spoofed packet appears to come from a different address, and they hide the true source of the attack. Denial of service attacks that use spoofing typically randomly choose addresses from the entire IP address space, though more sophisticated spoofing mechanisms might avoid unroutable addresses or unused portions of the IP address space. The proliferation of large botnets makes spoofing less important in denial of service attacks, but attackers typically have spoofing available as a tool, if they want to use it, so defenses against denial-of-service attacks that rely on the validity of the source IP address in attack packets might have trouble with spoofed packets.

It is a vesicular cell-rich cartilage due to the large, spherical and vacuolated chondrocytes with no homologies in other arthropods. Other type of cartilage found in \"Limulus polyphemus\" is the endosternite cartilage, a fibrous-hyaline cartilage with chondrocytes of typical morphology in a fibrous component, much more fibrous than vertebrate hyaline cartilage, with mucopolysaccharides immunoreactive against chondroitin sulfate antibodies. There are homologous tissues to the endosternite cartilage in other arthropods. The embryos of \"Limulus polyphemus\" express ColA and hyaluronan in the gill cartilage and the endosternite, which indicates that these tissues are fibrillar-collagen-based cartilage. The endosternite cartilage forms close to Hh-expressing ventral nerve cords and expresses ColA and SoxE, a Sox9 analog. This is also seen in gill cartilage tissue. In cephalopods, the models used for the studies of cartilage are \"Octopus vulgaris\" and \"Sepia officinalis\". The cephalopod cranial cartilage is the invertebrate cartilage that shows more resemblance to the vertebrate hyaline cartilage. The growth is though to take place throughout the movement of cells from the periphery to the center. The chondrocytes present different morphologies related to their position in the tissue. The embryos of \"Sepia officinalis\" express ColAa, ColAb and hyaluronan in the cranial cartilages and other regions of chondrogenesis. This implies that the cartilage is fibrillar-collagen-based. The \"Sepia officinalis\" embryo expresses hh, whose presence causes ColAa and ColAb expression and is also able to maintain proliferating cells undiferentiated. It has been observed that this species presents the expression SoxD and SoxE, analogs of the vertebrate Sox5/6 and Sox9, in the developing cartilage.

In november 1857, fisherman Hans Kopp was sailing to a Neolithic dwelling near Concise from Lake Biel under orders from Colonel Friedrich Schwab when he spotted an interesting spot near La Tène. He stopped and started investigating, and found within an hour around 40 iron objects, among which 8 spearheads and 12 swords. At that time, that is before the Jura water correction, the lake level was 2.7 m higher, and therefore, the site was 60 to 70 cm underwater. The discoveries made by Kopp went into Friedrich Shwab private collection until his death when they were given to the city of Biel/Bienne. The first scholars studying the site, colonel Friedrich Schwab and Ferdinand Keller did not not give the site a particular interest. However when Édouard Desor, professor of geology and paleontology heard of the discoveries, around a year later, he immediately realised the potential of La Tène within the Three-age system. In 1866, the first International congress of prehistoric archaeology and anthropology took place in Neuchâtel, Desor advocated the site of La Tène as the reference for the prehistoric Iron Age. A few years later, during a later meeting of the congress in Stockholm, it was decided to divide the Iron Age in Europe in two periods.

In 1907, on an initiative of the History and Archaeology society of Neuchâtel with a support from the Canton of Neuchâtel, a well organized excavation started. The excavation, lead by William Wavre and then Paul Vouga (1909) consisted in systematically emptying the old river Thielle bed. This methodical excavation lasted until 1917 and brought to light a large corpus of remarkably culturally similar artifacts. Six years later, Vouga published a monograph in the form of a typological inventory of the excavation discoveries where he did not try to suggest an interpretation of the site's function. The publication was considered disappointing, because Vouga did not use technics that were already known at the time, such as studying the site's stratigraphy. However, Vouga's monograph remains useful for the chronotypological studies of the second Iron Age.

A carillon bell is a cast bronze cup-shaped bell whose partial tones are in such harmonious relationship to each other as to permit many such bells to be sounded together in varied chords with harmonious and concordant effect.\" The GCNA defines a \"traditional carillon\" as one played from a carillon mechanical (not electrified) baton keyboard, and a \"non-traditional carillon\" as a musical instrument with bells, but played by automated mechanical or electro-mechanical means, or from an electrical or electronic keyboard. Since each note is produced by an individual bell, a carillon's musical range is determined by the number of bells it has. Different names are assigned to instruments based on the number of bells they comprise: The Riverside Carillon in New York City has the largest tuned carillon bell in the world, which sounds C (two octaves below middle C). Travelling or mobile carillons are not placed in a tower, but can be transported. Some of them can even be played indoors—in a concert hall or church—like the mobile carillon of Frank Steijns. Poorly tuned bells often give an \"out of tune\" impression and also can be out of tune with themselves. This is due to the unusual harmonic characteristics of foundry bells, which have strong overtones above and below the fundamental frequency. There is no standard pitch range for the carillon. In general, a concert carillon will have a minimum of 48 bells. The range of any given instrument usually depends on funds available for the fabrication and installation of the instrument: more money allows more bells to be cast, especially the larger, more costly ones.

Because of the acoustic peculiarities of a carillon bell (the prominence of the minor third, and the lack of damping of sound), music written for other instruments needs to be arranged specifically for the carillon. The combination of carillon and other instruments, while possible, is generally not a happy marriage. The carillon is generally far too loud to perform with most other concert instruments.

Amnesty after a war helps end a conflict. While laws against treason, sedition, etc. are retained to discourage future traitors during future conflicts, it makes sense to forgive past offenders, after the enemy no longer exists which had attracted their support but a significant number remains in flight from authorities. Amnesty is often used to get people to turn in contraband, as in the case of China's gun restrictions, or the Kansas City ban on pit bulls. Advantages of using amnesty may include avoiding expensive prosecutions (especially when massive numbers of violators are involved); prompting violators to come forward who might otherwise have eluded authorities; and promoting reconciliation between offenders and society. An example of the latter was the amnesty that was granted to conscientious objectors and draft evaders in the wake of the Vietnam War in the 1970s, in an effort by President Carter to heal war wounds, given that both the war and the draft were over. An example of an argument made for amnesty for illegal immigrants is that they would be allowed to qualify for higher paying jobs, scholarships, and other services. According to the Center for Study of Immigration Integration, if California alone were to adopt an amnesty program, they would benefit by $16 billion (Pastor, 2010). With amnesty, immigrants can seek out higher education. A RAND study found that, by the age of 30, a Mexican immigrant woman who becomes a legal resident can obtain a college degree. With a college degree she will pay $5,300 more in taxes and cost $3,900 less in government expenses each year compared to a high-school dropout with similar characteristics.

In contrast, workers with a bachelor's degree earned $962 per week and had an unemployment rate of 2.3 percent, while those with a doctorate earned $1,441 and had an unemployment rate of only 1.4 percent (Gonzales, 2010).", "section_level": 1}, {"title": "Controversy.", "content": "Amnesty can at times raise questions of justice.

David Smock noted, \"The downside of it is the impunity that it implies; that people can commit atrocities and say that they will only stop if they are given amnesty...\" A controversial issue in the United States is whether illegal immigrants should be granted some form of amnesty. It is proposed that illegal immigrants be able to come forward and immediately receive probationary status. California Republican Governor Arnold Schwarzenegger said an amnesty program similar to the one the federal government undertook in the late 1980s would be ill-advised today. It just didn't work. \"It backfired big-time. It sent the wrong message: You come here illegally, and then we go and give you amnesty. So then, the next million come and they say, 'Hey, we get amnesty, this is really terrific'.\" Some allege that at the national level an amnesty program would cost $2.6 trillion. This would only include the costs for the first year. The Federal Government would need to hire additional workers to help register immigrants, increasing costs for labor and or facilities. It is also alleged that an amnesty program would draw far more immigrants into the U.S. to receive amnesty, so the costs would continue to increase. Some allege that due to the large number of illegal immigrants residing in the U.S., the government had to hire outside contractors. This led to mass cases of fraudulent activity. Illegal immigrants were paying off workers to falsify information, grant amnesty for family and or friends, and providing other relevant services. Controversies also raise towards amnesties given to alleged perpetrators of the most serious crimes of international law (or crimes of the \"Jus Cogens\" which include genocide, crimes against humanity, war crimes, and aggression). Courts have rejected amnesties for such crimes, such as the International Criminal Tribunal for the former Yugoslavia and the Special Court for Sierra Leone. But scholars have suggested that there should be room for amnesties which were imperative necessities to achieve peace and accompanied by effective Truth and Reconciliation Commissions. One particular case was in Uruguay: the controversial Law on the Expiration of the Punitive Claims of the State pretended to put an end to unsolved issues deriving from 12 years of civic-military dictatorship; local human rights organizations challenged that law and called a referendum in 1989 which confirmed the law by 56% of the popular vote.", "section_level": 1}], "src_summary": "Amnesty (from the Greek ἀμνηστία \"amnestia\", \"forgetfulness, passing over\") is defined as \"A pardon extended by the government to a group or class of people, usually for a political offense; the act of a sovereign power officially forgiving certain classes of people who are subject to trial but have not yet been convicted.\" An amnesty constitutes more than a pardon, in so much as it obliterates all legal remembrance of the offense.

Key concepts in stratigraphy involve understanding how certain geometric relationships between rock layers arise and what these geometries imply about their original depositional environment. The basic concept in stratigraphy, called the law of superposition, states: in an undeformed stratigraphic sequence, the oldest strata occur at the base of the sequence. Chemostratigraphy studies the changes in the relative proportions of trace elements and isotopes within and between lithologic units. Carbon and oxygen isotope ratios vary with time, and researchers can use those to map subtle changes that occurred in the paleoenvironment. This has led to the specialized field of isotopic stratigraphy.

The geologic time scale was developed during the 19th century, based on the evidence of biologic stratigraphy and faunal succession. This timescale remained a relative scale until the development of radiometric dating, which gave it and the stratigraphy it was based on an absolute time framework, leading to the development of chronostratigraphy.

The ultimate aim of chronostratigraphy is to place dates on the sequence of deposition of all rocks within a geological region, and then to every region, and by extension to provide an entire geologic record of the Earth. A gap or missing strata in the geological record of an area is called a stratigraphic hiatus. This may be the result of a halt in the deposition of sediment. Alternatively, the gap may be due to removal by erosion, in which case it may be called a stratigraphic vacuity. It is called a \"hiatus\" because deposition was \"on hold\" for a period of time.

The method works by collecting oriented samples at measured intervals throughout a section. The samples are analyzed to determine their detrital remanent magnetism (DRM), that is, the polarity of Earth's magnetic field at the time a stratum was deposited. For sedimentary rocks this is possible because, as they fall through the water column, very fine-grained magnetic minerals (< 17 μm) behave like tiny compasses, orienting themselves with Earth's magnetic field. Upon burial, that orientation is preserved. For volcanic rocks, magnetic minerals, which form in the melt, orient themselves with the ambient magnetic field, and are fixed in place upon crystallization of the lava. Oriented paleomagnetic core samples are collected in the field; mudstones, siltstones, and very fine-grained sandstones are the preferred lithologies because the magnetic grains are finer and more likely to orient with the ambient field during deposition. If the ancient magnetic field were oriented similar to today's field (North Magnetic Pole near the North Rotational Pole), the strata would retain a normal polarity. If the data indicate that the North Magnetic Pole were near the South Rotational Pole, the strata would exhibit reversed polarity. Results of the individual samples are analyzed by removing the natural remanent magnetization (NRM) to reveal the DRM. Following statistical analysis, the results are used to generate a local magnetostratigraphic column that can then be compared against the Global Magnetic Polarity Time Scale.

In the confusion, he meets Niketas Choniates and saves his life. Niketas is amazed by his language genius, speaking many languages he has never heard, and on the question: if he is not part of the crusade, who is he? Baudolino begins to recount his life story to Niketas. His story begins in 1155, when Baudolino – a highly talented Italian peasant boy – is sold to and adopted by the emperor Frederick I. At court and on the battlefield, he is educated in reading and writing Latin and learns about the power struggles and battles of northern Italy at the time. He is sent to Paris to become a scholar. In Paris, he gains friends (such as the Archpoet, Abdul, Robert de Boron and Kyot, the purported source of Wolfram von Eschenbach's \"Parzival\") and learns about the legendary kingdom of Prester John. From this event onward, Baudolino dreams of reaching this fabled land. The earlier parts of the story follow the general historical and geographical outlines of 12th-century Europe, with special emphasis on the Emperor Frederick's futile efforts to subdue the increasingly independent and assertive city states of Northern Italy. Baudolino, being both a beloved adopted son to the Emperor and a loyal native of the newly founded and highly rebellious town of Alessandria, plays a key role in effecting reconciliation between the Emperor and the Alessandria townspeople, who are led by Baudolino's biological father; a way is found for the Emperor to recognize Alessandria's independence without losing face. (It is no accident that Alessandria is Umberto Eco's own hometown.) During the siege, Baudolino works on the side of Frederick Barbarossa, but concocts a plan to help win the Alessandrian townspeople some independence. He attempts to convince the emperor's forces that Alessandria is more prepared for a siege than them through stuffing a cow with the last of Alessandria's wheat and sends the cow out to the Emperor's forces. When the cow is cut open, it reveals a full belly of wheat. The emperor's forces are convinced that Alessandria is not worth besieging, and thus leave. The incident of the death of Emperor Frederick, while on the Third Crusade, is a key element of the plot. This part involves an element of secret history – the book asserts that Emperor Frederick had not drowned in a river, as history records, but died mysteriously at night while hosted at the castle of a sinister Armenian noble. This part also constitutes a historical detective mystery – specifically, a historical locked room mystery – with various suspects suggested, each of whom had a clever means of killing the Emperor, and with Baudolino acting as the detective. After the Emperor's death, Baudolino and his friends set off on a long journey, encompassing 15 years, to find the Kingdom of Prester John. From the moment when they depart eastwards, the book becomes pure fantasy – the lands which the band travels bearing no resemblance to the continent of Asia at that or any other historical time, being rather derived from the various myths which Europeans had about Asia – including the aforementioned Christian myth of the Kingdom of Prester John, as well as the Jewish myth of the Ten Lost Tribes and the River Sambation, and some earlier accounts provided by Herodotos. Baudolino meets eunuchs, unicorns, Blemmyes, skiapods and pygmies. At one point, he falls in love with a female satyr-like creature who recounts to him the full Gnostic creation myth; Gnosticism is a pervasive presence in another of Eco's novels, \"Foucault's Pendulum\". Philosophical debates are mixed with comedy, epic adventure and creatures drawn from the strangest medieval bestiaries. After many disastrous adventures, the destruction of Prester John's Kingdom by the White Huns followed by a long stint of slavery at the hands of the Old Man of the Mountain, Baudolino and surviving members of his band of friends return to Constantinople undergoing the agony of the Fourth Crusade – the book's starting point.

In the east, the Habsburg archdukes of Austria, based on the March of Carniola they held from 1335, had gained suzerainty over Istrian Pazin in 1374 and the port of Trieste in 1382. They also purchased Duino and Rijeka (Fiume) on the northern Adriatic coast in 1474, and inherited more territory in Friuli when the line of the Counts of Görz died out in 1500. In 1511, Emperor Maximilian I annexed the city of Gradisca from Venice. The Habsburgs did little initially to consolidate or develop their holdings in the Littoral. The supremacy of the Republic of Venice in the Adriatic, and the attention to the threat posed by an expanding Ottoman Empire, gave the Austrian archdukes little opportunity to enlarge their coastal possessions. Incorporated into the Austrian Circle of the Holy Roman Empire, Görz, Trieste and Istria remained separately administered and retained their autonomy until the 18th century. Emperor Charles VI increased the sea power of the Habsburg Monarchy by making peace with the Ottomans and declaring free shipping in the Adriatic. In 1719, Trieste and Fiume were made free ports. In 1730, administration of the Littoral was unified under the Intendancy in Trieste. However, in 1775, Emperor Joseph II divided the administration of the two main ports, assigning Trieste as the port for the Austrian \"hereditary lands\" and Fiume for the Kingdom of Hungary. Shortly after, Trieste was merged with the Princely County of Gorizia and Gradisca in the north. During the Napoleonic Wars, the Habsburg Monarchy gained Venetian lands in the Istrian Peninsula and the Quarnero (Kvarner) Islands as part of the Treaty of Campo Formio of 1797. However, these territories and all of the new Austrian Empire's Adriatic lands were soon lost to the French Empire's puppet state, the Kingdom of Italy by the Treaty of Pressburg of 1805. The 1809 Treaty of Schönbrunn then transferred the area to the Illyrian Provinces which were directly ruled by France. With Napoleon's defeats, the Austrian Empire regained the region. In 1813, all of the Littoral including Trieste, Gorizia and Gradisca, all of Istria, the Quarnero Islands, Fiume, and the hinterland of Fiume, Civil Croatia, including Karlstadt (Karlovac), became one administrative unit. From 1816, the Littoral was a part of the Austrian Empire's Kingdom of Illyria. In 1822, Fiume and Civil Croatia were separated from the territory and ceded to the Kingdom of Hungary (and in 1849 to Croatia). The Littoral was officially the Trieste (\"Triest\") Province, one of two provinces (or \"gouvernements\") of the Kingdom, the other being Laibach (Ljubljana). It was subdivided into four districts (\"kreis\"): Gorizia (\"Görz\"; including Gorizia and the Julian March), Istria (\"Istrien\"; Eastern Istria and the Quarnero Islands), Trieste (\"Triest\"; the Trieste hinterland and Western Istria), and Trieste city (\"Triester Stadtgebiet\"). Around 1825, the Littoral was reorganized into only two subdivisions: Istria with its capital at Mitterburg (Pisino/Pazin) and Gorizia with Trieste and its immediate surroundings under the direct control of the crown and separate from the local administrative structure. In 1849, the Kingdom of Illyria was dissolved and the Littoral became a separate crown land with a governor in Trieste. It was formally divided into the Margravate of Istria and the Princely County (\"Gefürstete Grafschaft\") of Gorizia and Gradisca with Trieste remaining separate from both. By the 1861 February Patent, Gorizia and Gradisca and Istria became administratively separate entities and, in 1867, Trieste received separate status as well, and the Littoral was divided into the three crown lands of the Imperial Free City of Trieste and its suburbs, the Margraviate of Istria, and the Princely County of Gorizia and Gradisca, which each had separate administrations and Landtag assemblies, but were all subject to a \"k.k.\" statholder at Trieste. Following the dissolution of Austria-Hungary, the Littoral fell within Italy's newly expanded borders as part of the Julian March. An area of similar extent under the name of Adriatic Littoral (\"Adriatisches Küstenland\") was one of the operational zones of German forces during World War II after the capitulation of Italy in September 1943 until the end of the war. After World War II, most of it was included in the Second Yugoslavia. Today Croatia and Slovenia each hold portions of the territory, and the city of Trieste remains under Italian rule.

He was connected with the Habsburgs through his grandmother Eleonore, daughter of Emperor Ferdinand III. He was very close to his brother Charles and sister Anne Charlotte. Emperor Charles VI favoured the family, who, besides being his cousins, had served the house of Austria with distinction. He had designed to marry his daughter Maria Theresa to Francis' older brother Leopold Clement. On Leopold Clement's death, Charles adopted the younger brother as his future son-in-law. Francis was brought up in Vienna with Maria Theresa with the understanding that they were to be married, and a real affection arose between them. At the age of 15, when he was brought to Vienna, he was established in the Silesian Duchy of Teschen, which had been mediatised and granted to his father by the emperor in 1722. Francis succeeded his father as Duke of Lorraine in 1729. In 1731 he was initiated into freemasonry (Grand Lodge of England) by John Theophilus Desaguliers at a specially convened lodge in The Hague at the house of the British Ambassador, Philip Stanhope, 4th Earl of Chesterfield. During a subsequent visit to England, Francis was made a Master Mason at another specially convened lodge at Houghton Hall, the Norfolk estate of British Prime Minister Robert Walpole. Maria Theresa arranged for Francis to become \"Lord Lieutenant\" (locumtenens) of Hungary in 1732. He was not excited about this position, but Maria Theresa wanted him closer to her. In June 1732 he agreed to go to Pressburg. When the War of the Polish Succession broke out in 1733, France used it as an opportunity to seize Lorraine, since France's prime minister, Cardinal Fleury, was concerned that, as a Habsburg possession, it would bring Austrian power too close to France. A preliminary peace was concluded in October 1735 and ratified in the Treaty of Vienna in November 1738. Under its terms, Stanisław I, the father-in-law of King Louis XV and the losing claimant to the Polish throne, received Lorraine, while Francis, in compensation for his loss, was made heir to the Grand Duchy of Tuscany, which he would inherit in 1737. Although fighting stopped after the preliminary peace, the final peace settlement had to wait until the death of the last Medici Grand Duke of Tuscany, Gian Gastone de' Medici in 1737, to allow the territorial exchanges provided for by the peace settlement to go into effect. In March 1736 the Emperor persuaded Francis, his future son-in-law, to secretly exchange Lorraine for the Grand Duchy of Tuscany. France had demanded that Maria Theresa's fiancé surrender his ancestral Duchy of Lorraine to accommodate the deposed King of Poland. The Emperor considered other possibilities (such as marrying her to the future Charles III of Spain) before announcing the engagement of the couple. If something were to go wrong, Francis would become governor of the Austrian Netherlands. Elisabeth of Parma had also wanted the Grand Duchy of Tuscany for her son Charles III of Spain; Gian Gastone de' Medici was childless and was related to Elisabeth via her great-grandmother Margherita de' Medici. As a result, Elisabeth's sons could claim by right of being a descendant of Margherita. On 31 January 1736 Francis agreed to marry Maria Theresa. He hesitated three times (and laid down the feather before signing).

It was his good fortune to govern the Austrian dominions and to be head of the Empire, during the years in which his trusted general, Prince Eugene of Savoy, either acting alone in Italy or with the Duke of Marlborough in Germany and Flanders, was beating the armies of Louis XIV of France. During the whole of his reign, Hungary was disturbed by the conflict with Francis Rákóczi II, who eventually took refuge in the Ottoman Empire. The emperor reversed many of the authoritarian measures of his father, thus helping to placate opponents. He began the attempts to settle the question of the Austrian inheritance by a pragmatic sanction, which was continued by his brother Charles VI. In 1710, Joseph extended his father's edict of outlawry against the Romani (Gypsies) in the Habsburg lands. Per Leopold, any Romani who entered the kingdom was to be declared an outlaw by letters patent and if the same person returned to Bohemia a second time \"treated with all possible severity\". Joseph ordered that in the Kingdom of Bohemia they were to have their right ears cut off; in the March of Moravia, the left ear was to be cut off; in Austria, they would be branded on the back with a branding iron, representing the gallows. These mutilations were to enable the authorities to identify Romani who had been outlawed and returned. Joseph's edict specified \"that all adult males were to be hanged without trial, whereas women and young males were to be flogged and banished forever.\" Officials who failed to enforce the edict could be fined 100 Reichsthaler.

Parishes may extend into different counties or hundreds and historically many parishes comprised extra outlying portions in addition to its principal district, usually being described as 'detached' and intermixed with the lands of other parishes. Church of England parishes nowadays all lie within one of 44 dioceses divided between the provinces of Canterbury, 30 and York, 14. Each parish normally has its own parish priest (either a vicar or rector, owing to the vagaries of the feudal tithe system: rectories usually having had greater income) and perhaps supported by one or more curates or deacons - although as a result of ecclesiastical pluralism some parish priests might have held more than one parish living, placing a curate in charge of those where they do not reside. Now, however, it is common for a number of neighbouring parishes to be placed under one benefice in the charge of a priest who conducts services by rotation, with additional services being provided by lay readers or other non-ordained members of the church community. A chapelry was a subdivision of an ecclesiastical parish in England, and parts of Lowland Scotland up to the mid 19th century. It had a similar status to a township but was so named as it had a chapel which acted as a subsidiary place of worship to the main parish church. In England civil parishes and their governing parish councils evolved in the 19th century as ecclesiastical parishes began to be relieved of what became considered to be civic responsibilities. Thus their boundaries began to diverge. The word \"parish\" acquired a secular usage.

Matthias Alexander, Elsa Gindler, and Gerda Alexander, the Feldenkrais Method originated in the efforts of its founder to work with his own bodily problem. In the case of Moshé Feldenkrais, it was a chronically injured knee. Feldenkrais first injured his knee while playing soccer in British-controlled Palestine in the 1920s. He reinjured it while negotiating the slippery decks of submarines while working as a scientist at the British Naval station at Fairlie, North Ayrshire, Scotland during the Second World War. By that time Feldenkrais was a judo teacher and had mostly completed the work toward a D.Sc. under the guidance of Nobel laureate Frédéric Joliot-Curie. Facing the prospect of a surgery that could leave him with a life-long limp, Feldenkrais decided to apply the knowledge gained from his study of physics, engineering, and martial arts to an intensive self-study of his own movement habits. When his work provided him with relief, allowing him to avoid the knee surgery, he began exploring the methods he developed on himself with a small group of people at Fairlie, including scientific colleague John Desmond Bernal and John Boyd-Orr, Nobel laureate and first president of the World Academy of Art and Science. After serving as head of electronic engineering for the Israeli Army in newly formed Israel from 1951 to 1953, Feldenkrais devoted the rest of his life, from age 50 onward, to developing and teaching self-awareness through movement lessons. From the 1950s till his death in 1984, he taught continuously in his home city of Tel Aviv. Feldenkrais gained recognition in part through media accounts of his work with prominent individuals, including Israeli Prime Minister David Ben-Gurion. Beginning in the late 1950s, Feldenkrais made trips to teach in Europe and America. Several hundred people became certified Feldenkrais practitioners through trainings he held in San Francisco from 1975 to 1978 and in Amherst, Massachusetts from 1980 to 1984. Anticipating the need for an institutional structure to carry on his teaching, he helped found the Feldenkrais Guild of North America in 1977. Feldenkrais developed the conceptual framework of his method in part through the publication of six books, beginning with \"Body and Mature Behavior\" (1949) and ending with the posthumously published \"The Potent Self\" (1985). Since Feldenkrais' death, the international Feldenkrais community has used a guild structure to regulate its activity, with training accreditation boards in the Americas, Europe, and Australasia overseeing guilds and associations in eighteen member countries. \"The Feldenkrais Journal\", the annual publication of the Feldenkrais Guild of North America, serves as a forum for the Feldenkrais community to discuss the method and its applications.", "section_level": 1}, {"title": "Influences.", "content": "The development of the Feldenkrais Method was influenced by Moshe Feldenkrais's involvement in the martial arts. After meeting Kano Jigoro, the founder of Judo, while living in Paris in the 1930s, Feldenkrais transitioned to that practice. One of the main influences of judo on the Feldenkrais Method is the differentiation between rote exercise and attentive movement: \"the methods of physical exercise in vogue... exert only the muscles without any other goal, and one needs much will to bind oneself unfailingly to one of these methods\", wrote Feldenkrais in 1952. \"Judo is very different, each movement has a specific goal which is reached after a precise and supple execution.\" Before he focused on the creation of his own method, Feldenkrais influenced the teaching of martial arts in Western Europe through the publication of five books on jiujitsu and judo, as well as teaching at practice centers in France and Great Britain. Feldenkrais was born into an Hasidic family and community, and he acknowledged the influence of Hasidic Judaism on his method. In David Kaetz's biography, \"Making Connections: Roots and Resonance in the Life of Moshe Feldenkrais\" (2007), he argues many lines of influence can be found between the Judaism of Feldenkrais's upbringing and the Feldenkrais Method – for instance, the use of paradox as a pedagogical tool. Feldenkrais also acknowledged the influence of the Russian spiritualist George Gurdjieff on his work, in particular Gurdjieff's teachings on automatism and freedom in embodiment. Feldenkrais earned his doctorate in a program at the Sorbonne intended to bridge theoretical physics and industrial engineering. Mark Reese, another biographer of the teacher, says that Feldenkrais brought this emphasis on practical scientific inquiry to the understanding of embodiment expressed through his method: \"Feldenkrais was critical of the appropriation of the term 'energy' to express immeasurable phenomena or to label experiences that people had trouble describing,\" notes Reese. \"He was impatient when someone invoked energy in pseudoscientific 'explanations' that masked a lack of understanding. In such cases he urged skepticism and scientific discourse. He encouraged empirical and phenomenological narratives that could lead to insights.\" Feldenkrais incorporated the views of other scientists into his teaching; for instance, he asked questions of both the neurosurgeon Karl H. Pribram and the cyberneticist Heinz von Foerster at trainings in San Francisco in the mid-1970s. Cybernetics, also known as dynamic systems theory, continued to influence the Feldenkrais Method in the 1990s through the work of human development researcher Esther Thelen.", "section_level": 1}], "src_summary": "The Feldenkrais Method is a type of exercise therapy devised by Israeli Moshé Feldenkrais (1904–1984) during the mid-20th century.

After World War II, her family, being Germans, were expelled from their home on what had become Polish territory. They crossed the new Oder-Neisse border in 1945 and settled in Mecklenburg, in what would become the German Democratic Republic, or East Germany. She studied literature at the University of Jena and the University of Leipzig. After her graduation, she worked for the German Writers' Union and became an editor for a publishing company. While working as an editor for publishing companies \"Verlag Neues Leben\" and \"Mitteldeutscher Verlag\" and as a literary critic for the journal \"Neue deutsche Literatur\", Wolf was provided contact with antifascists and Communists, many of whom had either returned from exile or from imprisonment in concentration camps. Her writings discuss political, economic, and scientific power, making her an influential spokesperson in East and West Germany during post-World War II for the empowerment of individuals to be active within the industrialized and patriarchal society. She joined the Socialist Unity Party of Germany (SED) in 1949 and left it in June 1989, six months before the Communist regime collapsed. She was a candidate member of the Central Committee of the SED from 1963 to 1967. Stasi records found in 1993 showed that she worked as an informant (\"Inoffizieller Mitarbeiter\") during the years 1959–61. The Stasi officers criticized what they called her \"reticence\", and they lost interest in her cooperation. She was herself then closely watched for nearly 30 years. During the Cold War, Wolf was openly critical of the leadership of the GDR, but she maintained a loyalty to the values of socialism and opposed German reunification. In 1961, she published \"Moskauer Novelle\" (\"Moscow Novella\"). However, Wolf's breakthrough as a writer came in 1963 with the publication of \"Der geteilte Himmel\" (\"Divided Heaven\", \"They Divided the Sky\").

Central themes in her work are German fascism, humanity, feminism, and self-discovery. In many of her works, Wolf uses illness as a metaphor.

Symbolically, if we have a data set consisting of the values formula_5, then the arithmetic mean formula_6 is defined by the formula: (See summation for an explanation of the summation operator). For example, consider the monthly salary of 10 employees of a firm: 2500, 2700, 2400, 2300, 2550, 2650, 2750, 2450, 2600, 2400. The arithmetic mean is If the data set is a statistical population (i.e., consists of every possible observation and not just a subset of them), then the mean of that population is called the population mean. If the data set is a statistical sample (a subset of the population), we call the statistic resulting from this calculation a sample mean. The arithmetic mean can be similarly defined for vectors in multiple dimension, not only scalar values; this is often referred to as a centroid. More generally, because the arithmetic mean is a convex combination (coefficients sum to 1), it can be defined on a convex space, not only a vector space.", "section_level": 1}, {"title": "Motivating properties.", "content": "The arithmetic mean has several properties that make it useful, especially as a measure of central tendency. These include:", "section_level": 1}, {"title": "Contrast with median.", "content": "The arithmetic mean may be contrasted with the median. The median is defined such that no more than half the values are larger than, and no more than half are smaller than, the median. If elements in the data increase arithmetically, when placed in some order, then the median and arithmetic average are equal. For example, consider the data sample formula_15. The average is formula_16, as is the median. However, when we consider a sample that cannot be arranged so as to increase arithmetically, such as formula_17, the median and arithmetic average can differ significantly. In this case, the arithmetic average is 6.2 and the median is 4. In general, the average value can vary significantly from most values in the sample, and can be larger or smaller than most of them. There are applications of this phenomenon in many fields. For example, since the 1980s, the median income in the United States has increased more slowly than the arithmetic average of income.", "section_level": 1}, {"title": "Generalizations.", "content": "", "section_level": 1}, {"title": "Weighted average.", "content": "A weighted average, or weighted mean, is an average in which some data points count more heavily than others, in that they are given more weight in the calculation. For example, the arithmetic mean of formula_18 and formula_19 is formula_20, or equivalently formula_21. In contrast, a \"weighted\" mean in which the first number receives, for example, twice as much weight as the second (perhaps because it is assumed to appear twice as often in the general population from which these numbers were sampled) would be calculated as formula_22. Here the weights, which necessarily sum to the value one, are formula_23 and formula_24, the former being twice the latter. The arithmetic mean (sometimes called the \"unweighted average\" or \"equally weighted average\") can be interpreted as a special case of a weighted average in which all the weights are equal to each other (equal to formula_25 in the above example, and equal to formula_26 in a situation with formula_3 numbers being averaged).", "section_level": 2}, {"title": "Continuous probability distributions.", "content": "If a numerical property, and any sample of data from it, could take on any value from a continuous range, instead of, for example, just integers, then the probability of a number falling into some range of possible values can be described by integrating a continuous probability distribution across this range, even when the naive probability for a sample number taking one certain value from infinitely many is zero. The analog of a weighted average in this context, in which there are an infinite number of possibilities for the precise value of the variable in each range, is called the \"mean of the probability distribution\". A most widely encountered probability distribution is called the normal distribution; it has the property that all measures of its central tendency, including not just the mean but also the aforementioned median and the mode (the three M's), are equal to each other. This equality does not hold for other probability distributions, as illustrated for the lognormal distribution here.", "section_level": 2}, {"title": "Angles.", "content": "Particular care must be taken when using cyclic data, such as phases or angles.

A solution to this problem is to use the optimization formulation (viz., define the mean as the central point: the point about which one has the lowest dispersion), and redefine the difference as a modular distance (i.e., the distance on the circle: so the modular distance between 1° and 359° is 2°, not 358°).", "section_level": 1}, {"title": "Symbols and encoding.", "content": "The arithmetic mean is often denoted by a bar, for example as in formula_1 (read formula_2 \"bar\").

The film was selected for screening at the 1995 Cannes Festival. In 1997, Diesel made his first feature-length film, \"Strays\", an urban drama in which he played a gang leader whose love for a woman inspires him to try to change his ways. Written, directed, and produced by Diesel, the film was selected for competition at the 1997 Sundance Festival, leading to an MTV deal to turn it into a series. Director Steven Spielberg took notice of Diesel after seeing him in \"Multi-Facial\" and cast him in a small role as a soldier in his 1998 Oscar-winning war film \"Saving Private Ryan\".

The name \"Tighina\" is found in documents from the second half of the 15th century. The town was the main Moldavian customs point on the commercial road linking the country to Tatar Crimea. During his reign of Moldavia, Stephen III had a small wooden fort built in the town to defend the settlement from Tatar raids. In 1538, the Ottoman sultan Suleiman the Magnificent conquered the town from Moldavia, and renamed it \"Bender\". Its fortifications were developed into a full fortress under the same name under the supervision of the Turkish architect Koji Mimar Sinan. The Ottomans used it to keep the pressure on Moldavia. At the end of the 16th century several unsuccessful attempts to retake the fortress were made: in the summer of 1574 Prince John III the Terrible led a siege on the fortress, as did Michael the Brave in 1595 and 1600. About the same time the fortress was attacked by Zaporozhian Cossacks. In the 18th century, the fort's area was expanded and modernized by the prince of Moldavia Antioh Cantemir, who carried out these works under Ottoman supervision. In 1713, the fortress, the town, and the neighboring village Varnița were the site of skirmishes (\"kalabalik\") between Charles XII of Sweden, who had taken refuge there with the Cossack Hetman Ivan Mazepa after his defeat in the Battle of Poltava, and Turks who wished to enforce the departure of the Swedish king. During the second half of the 18th century, the fortress fell three times to the Russians during the Russo-Turkish Wars (in 1770, 1789, and in 1806 without a fight). Along with Bessarabia, the city was annexed to the Russian Empire in 1812, and remained part of the Russian Governorate of Bessarabia until 1917. Many Ukrainians, Russians and Jews settled in or around Bender, and the town quickly became predominantly Russian-speaking. By 1897, speakers of Romanian and Moldovan made up only around 7% of Bender's population, while 33.4% were Jews. Tighina was part of the Moldavian Democratic Republic in 1917–1918, and after 1918, as part of Bessarabia, the city belonged to Romania, where it was the seat of Tighina County. In 1918, it was shortly controlled by the Odessa Soviet Republic which was driven out by the Romanian army. The local population was critical of Romanian authorities; pro-Soviet separatism remained popular. On Easter Day, 1919, the bridge over the Dniester River was blown up by the French Army in order to block the Bolsheviks from coming to the city. In the same year, there was a pro-Soviet uprising in Bender, attempting to attach the city to the newly founded Soviet Union. Several hundred communist workers and Red Army members from Bessarabia, headed by Grigori Stary, seized control in Bender on May 27. However, the uprising was crushed on the same day by the Romanian army. Romania launched a policy of Romanianization and the use of Russian was now discouraged and in certain cases restricted. In Bender, however, Russian continued to be the city's most widely spoken language, being native to 53% of its residents in 1930. Although their share had doubled, Romanian-speakers made up only 15%. Along with Bessarabia, the city was occupied by the Soviet Union on June 28, 1940, following an ultimatum. In the course of World War II, it was retaken by Romania in July 1941, and again by the USSR in August 1944.

On the other hand, some recent linguistic estimations suggest that Finno-Ugrian language arrived around the Baltic Sea considerably later, perhaps during the Early Bronze Age (ca. 1800 BCE). The oldest known endonym of the Estonians is, literally meaning \"land people\" or \"country folk\". It was used up until the mid-19th century, when it was gradually replaced by \"Eesti rahvas\" \"Estonian people\" during the Estonian national awakening. \"Eesti\", the modern endonym of Estonia, is thought to be derived from the word \"Aestii\", the name given by the ancient Germanic people to the Baltic people living northeast of the Vistula River. The Roman historian Tacitus in 98 AD was the first to mention the \"\"Aestii\"\" people, and early Scandinavians called the land south of the Gulf of Finland \"\"Eistland\"\" ( is also the current word in Icelandic for Estonia), and the people \"\"eistr\"\". Proto-Estonians (as well as other speakers of the Finnish language group) were also called \"Chuds\" () in Old East Slavic chronicles.

By the 18th century the self-denomination spread among Estonians along with the older. Anton thor Helle's translation of the Bible into Estonian appeared in 1739, and the number of books and brochures published in Estonian increased from 18 in the 1750s to 54 in the 1790s. By the end of the century more than a half of adult peasants could read. The first university-educated intellectuals identifying themselves as Estonians, including Friedrich Robert Faehlmann (1798–1850), Kristjan Jaak Peterson (1801–1822) and Friedrich Reinhold Kreutzwald (1803–1882), appeared in the 1820s. The ruling elites had remained predominantly German in language and culture since the conquest of the early 13th century. Garlieb Merkel (1769–1850), a Baltic-German Estophile, became the first author to treat the Estonians as a nationality equal to others; he became a source of inspiration for the Estonian national movement, modelled on Baltic German cultural world before the middle of the 19th century. However, in the middle of the century, the Estonians became more ambitious and started leaning toward the Finns as a successful model of national movement and, to some extent, toward the neighbouring Latvian national movement. By the end of 1860 the Estonians became unwilling to reconcile with German cultural and political hegemony. Before the attempts at Russification in the 1880s, their view of Imperial Russia remained positive. Estonians have strong ties to the Nordic countries stemming from important cultural and religious influences gained over centuries during Scandinavian and German rule and settlement. Indeed, Estonians consider themselves Nordic rather than Baltic, in particular because of close ethnic and linguistic affinities with the Finns. After the Treaty of Tartu (1920) recognised Estonia's 1918 independence from Russia, ethnic Estonians residing in Russia gained the option of opting for Estonian citizenship (those who opted were called \"optandid\" - 'optants') and returning to their fatherland.

Some of these refugees and their descendants returned to Estonia after the nation regained its independence in 1991. Over the years of independence, increasing numbers of Estonians have chosen to work abroad, primarily in Finland, but also in other European countries (mostly in the UK, Benelux, Sweden, and Germany), making Estonia the country with the highest emigration rate in Europe. This is at least partly due to the easy access to oscillating migration to Finland. Recognising the problems arising from both low birth rate and high emigration, the country has launched various measures to both increase the birth rate and to lure migrant Estonians back to Estonia.

Another method targeting the snail host, mechanical disturbance of snail habitat, has been also tried in some areas of North America and Lake Annecy in France, with promising results.

According to the \"Chronicle of the Morea\", Andravida, like most of the towns and regions of the northern and western Peloponnese, was captured without a fight in 1205 by the Crusader leader William of Champlitte, and it was there that the local Greek magnates and lords of Elis and of the mountains of Skorta and Mesarea paid him homage and recognized him as their lord. Soon after the Frankish conquest, Andravida (known as \"Andreville\" in French, \"Andrevilla\" in Aragonese and \"Andravilla\" in Italian) became the residence of the princes of the newly established Principality of Achaea. As the medievalist Antoine Bon points out, Andravida's choice as the \"de facto\" capital of the principality rested on its favourable location: situated in the midst of the fertile plain of Elis, it was well provisioned and could sustain horses, it was located near the major port town of Glarentza, but not on the coast and hence not vulnerable to seaborne raids, and was equally far from the mountains of the central Peloponnese with their rebellious inhabitants. Consequently, despite its importance, it was never fortified. The town also became the seat of a Roman Catholic bishopric, attested since 1212, which assimilated the pre-existing Greek bishopric of Olena and retained the latter's name. Only a few traces survive of the Frankish town, and most of the testimony about its buildings comes from literary sources: a palace for the Princes; the Church of Saint Stephen, possibly belonging to the Franciscans; the Church and hospice of Saint James, given to the Teutonic Order in 1241 and serving as the burial place for the princely House of Villehardouin; the convent of Saint Nicholas of Carmel; and the Church of Saint Sophia, serviced by the Dominicans and the largest of them all, by virtue of which it often served as the site of assemblies and parliaments of the principality's nobility. Early 19th-century travellers like François Pouqueville and Jean Alexandre Buchon reported that the three churches were still largely extant, but today only Saint Sophia survives to a substantial extent. Like the rest of the Principality's remnants in Elis and Achaea, Andravida was conquered by the Despotate of the Morea in the late 1420s.

In order for this transcription to occur, several pol I-associated factors and DNA-specific trans-acting factors are required. In yeast, the most important are: UAF (upstream activating factor), TBP (TATA-box binding protein), and core binding factor (CBF)) which bind promoter elements and form the preinitiation complex (PIC), which is in turn recognized by RNA pol. In humans, a similar PIC is assembled with SL1, the promoter selectivity factor (composed of TBP and TBP-associated factors, or TAFs), transcription initiation factors, and UBF (upstream binding factor). RNA polymerase I transcribes most rRNA transcripts 28S, 18S, and 5.8S) but the 5S rRNA subunit (component of the 60S ribosomal subunit) is transcribed by RNA polymerase III. Transcription of rRNA yields a long precursor molecule (45S pre-rRNA) which still contains the ITS and ETS. Further processing is needed to generate the 18S RNA, 5.8S and 28S RNA molecules. In eukaryotes, the RNA-modifying enzymes are brought to their respective recognition sites by interaction with guide RNAs, which bind these specific sequences. These guide RNAs belong to the class of small nucleolar RNAs (snoRNAs) which are complexed with proteins and exist as small-nucleolar-ribonucleoproteins (snoRNPs). Once the rRNA subunits are processed, they are ready to be assembled into larger ribosomal subunits. However, an additional rRNA molecule, the 5S rRNA, is also necessary. In yeast, the 5S rDNA sequence is localized in the intergenic spacer and is transcribed in the nucleolus by RNA pol. In higher eukaryotes and plants, the situation is more complex, for the 5S DNA sequence lies outside the Nucleolus Organiser Region (NOR) and is transcribed by RNA pol III in the nucleoplasm, after which it finds its way into the nucleolus to participate in the ribosome assembly. This assembly not only involves the rRNA, but ribosomal proteins as well. The genes encoding these r-proteins are transcribed by pol II in the nucleoplasm by a \"conventional\" pathway of protein synthesis (transcription, pre-mRNA processing, nuclear export of mature mRNA and translation on cytoplasmic ribosomes). The mature r-proteins are then imported into the nucleus and finally the nucleolus. Association and maturation of rRNA and r-proteins result in the formation of the 40S (small) and 60S (large) subunits of the complete ribosome. These are exported through the nuclear pore complexes to the cytoplasm, where they remain free or become associated with the endoplasmic reticulum, forming rough endoplasmic reticulum (RER).

Ferrite crystals do not adopt the ordinary spinel structure, but rather the inverse spinel structure: One eighth of the tetrahedral holes are occupied by B cations, one fourth of the octahedral sites are occupied by A cations. and the other one fourth by B cation. It is also possible to have mixed structure spinel ferrites with formula [MFe][MFe]O where δ is the degree of inversion. The magnetic material known as \"ZnFe\" has the formula ZnFeO, with Fe occupying the octahedral sites and Zn occupy the tetrahedral sites, it is an example of normal structure spinel ferrite. Some ferrites adopt hexagonal crystal structure, like barium and strontium ferrites BaFeO (BaO:6FeO) and SrFeO (SrO:6FeO).

Because of their comparatively low losses at high frequencies, they are extensively used in the cores of RF transformers and inductors in applications such as switched-mode power supplies and loopstick antennas used in AM radios.

Next the powder is pressed into a shape, dried, and re-sintered. The shaping may be performed in an external magnetic field, in order to achieve a preferred orientation of the particles (anisotropy). Small and geometrically easy shapes may be produced with dry pressing. However, in such a process small particles may agglomerate and lead to poorer magnetic properties compared to the wet pressing process. Direct calcination and sintering without re-milling is possible as well but leads to poor magnetic properties. Electromagnets are pre-sintered as well (pre-reaction), milled and pressed. However, the sintering takes place in a specific atmosphere, for instance one with an oxygen shortage. The chemical composition and especially the structure vary strongly between the precursor and the sintered product. To allow efficient stacking of product in the furnace during sintering and prevent parts sticking together, many manufacturers separate ware using ceramic powder separator sheets. These sheets are available in various materials such as alumina, zirconia and magnesia. They are also available in fine, medium and coarse particle sizes. By matching the material and particle size to the ware being sintered, surface damage and contamination can be reduced while maximizing furnace loading.", "section_level": 2}, {"title": "Uses.", "content": "Ferrite cores are used in electronic inductors, transformers, and electromagnets where the high electrical resistance of the ferrite leads to very low eddy current losses.

Early computer memories stored data in the residual magnetic fields of hard ferrite cores, which were assembled into arrays of \"core memory\". Ferrite powders are used in the coatings of magnetic recording tapes. Ferrite particles are also used as a component of radar-absorbing materials or coatings used in stealth aircraft and in the absorption tiles lining the rooms used for electromagnetic compatibility measurements. Most common audio magnets, including those used in loudspeakers and electromagnetic instrument pickups, are ferrite magnets. Except for certain \"vintage\" products, ferrite magnets have largely displaced the more expensive Alnico magnets in these applications.

From 1918 to mid-1920, he published numerous poems, such as \"Mis ojos\" (\"My eyes\"), and essays in local magazines as Neftalí Reyes. In 1919, he participated in the literary contest Juegos Florales del Maule and won third place for his poem \"Comunión ideal\" or \"Nocturno ideal\". By mid-1920, when he adopted the pseudonym Pablo Neruda, he was a published author of poems, prose, and journalism. He is thought to have derived his pen name from the Czech poet Jan Neruda. The young poet's intention in publishing under a pseudonym was to avoid his father's disapproval of his poems. In 1921, at the age of 16, Neruda moved to Santiago to study French at the Universidad de Chile, with the intention of becoming a teacher. However, he was soon devoting all his time to writing poems and with the help of well-known writer Eduardo Barrios, he managed to meet and impress Don Carlos George Nascimento, the most important publisher in Chile at the time. In 1923, his first volume of verse, \"Crepusculario\" (\"Book of Twilights\"), was published by Editorial Nascimento, followed the next year by \"Veinte poemas de amor y una canción desesperada\" (\"Twenty Love Poems and A Desperate Song\"), a collection of love poems that was controversial for its eroticism, especially considering its author's young age. Both works were critically acclaimed and have been translated into many languages. Over the decades, \"Veinte poemas\" sold millions of copies and became Neruda's best-known work, though a second edition did not appear until 1932. Almost one hundred years later, Veinte Poemas still retains its place as the best-selling poetry book in the Spanish language. By the age of 20, Neruda had established an international reputation as a poet, but faced poverty. In 1926, he published the collection \"Tentativa del hombre infinito\" (\"The Attempt of the Infinite Man\") and the novel \"El habitante y su esperanza\" (\"The Inhabitant and His Hope\"). In 1927, out of financial desperation, he took an honorary consulship in Rangoon, the capital of the British colony of Burma, then administered from New Delhi as a province of British India. Rangoon was a place he had never heard of before. Later, mired in isolation and loneliness, he worked in Colombo (Ceylon), Batavia (Java), and Singapore. In Batavia the following year he met and married (6 December 1930) his first wife, a Dutch bank employee named Marijke Antonieta Hagenaar Vogelzang, known as Maruca.
-Phenylalanine (DLPA) is marketed as a nutritional supplement for its purported analgesic and antidepressant activities. -Phenylalanine is a mixture of -phenylalanine and -phenylalanine. The reputed analgesic activity of -phenylalanine may be explained by the possible blockage by -phenylalanine of enkephalin degradation by the enzyme carboxypeptidase A. The mechanism of -phenylalanine's supposed antidepressant activity may be accounted for by the precursor role of -phenylalanine in the synthesis of the neurotransmitters norepinephrine and dopamine. Elevated brain levels of norepinephrine and dopamine are thought to have an antidepressant effect. -Phenylalanine is absorbed from the small intestine and transported to the liver via the portal circulation. A small amount of -phenylalanine appears to be converted to -phenylalanine. -Phenylalanine is distributed to the various tissues of the body via the systemic circulation. It appears to cross the blood–brain barrier less efficiently than -phenylalanine, and so a small amount of an ingested dose of -phenylalanine is excreted in the urine without penetrating the central nervous system. -Phenylalanine is an antagonist at α2δ Ca calcium channels with a K of 980 nM. In the brain, -phenylalanine is a competitive antagonist at the glycine binding site of NMDA receptor and at the glutamate binding site of AMPA receptor. At the glycine binding site of NMDA receptor -phenylalanine has an apparent equilibrium dissociation constant (K) of 573 μM estimated by Schild regression which is considerably lower than brain -phenylalanine concentration observed in untreated human phenylketonuria. -Phenylalanine also inhibits neurotransmitter release at glutamatergic synapses in hippocampus and cortex with IC of 980 μM, a brain concentration seen in classical phenylketonuria, whereas -phenylalanine has a significantly smaller effect.", "section_level": 1}, {"title": "Commercial synthesis.", "content": "-Phenylalanine is produced for medical, feed, and nutritional applications, such as aspartame, in large quantities by utilizing the bacterium \"Escherichia coli\", which naturally produces aromatic amino acids like phenylalanine.

Three years later, work began to rebuild the structure. Under Archbishop Hartwig, the sanctuary expanded to the west with addition of a choir and crypt between 1000 and 1080. Archbishop Konrad I added the west towers from 1106 to 1147. This original church, thus experienced at least three extensive building and rebuilding campaigns during the early Middle Ages, the final result of which was a somewhat \"ad hoc\" Romanesque basilica. In 1598, the basilica was severely damaged, and after several failed attempts at restoration and reconstruction, Prince-Bishop Wolf Dietrich Raitenau (Archbishop from 1587–1612) finally ordered it demolished. Wolf Dietrich was a patron and supporter of modern Italian Baroque architecture, having seen it from its origins in Italy and particularly Rome. Indeed, it was Wolf Dietrich who was also responsible for the building of the nearby \"Alten Residenz\", which is today connected to the cathedral. Wolf Dietrich hired the Italian architect Vincenzo Scamozzi to prepare a plan for a comprehensive new Baroque building. Construction did not begin however until Wolf Dietrich's successor, Markus Sittich von Hohenems (Archbishop from 1612–19), in 1614 laid the cornerstone of the new cathedral. Santino Solari designed the current cathedral by dramatically altering the original Scamozzi plan. The new sanctuary was completed 1628, less than 15 years after construction began.

Wolfgang wrote a number of works for Marianne to perform, including the Prelude and Fugue in C, K. 394 (1782). Until 1785, he sent her copies of his piano concertos (up to No. 21) in St. Gilgen.

The most important aspect of MBE is the deposition rate (typically less than 3,000 nm per hour) that allows the films to grow epitaxially. These deposition rates require proportionally better vacuum to achieve the same impurity levels as other deposition techniques. The absence of carrier gases, as well as the ultra-high vacuum environment, result in the highest achievable purity of the grown films. In solid source MBE, elements such as gallium and arsenic, in ultra-pure form, are heated in separate quasi-Knudsen effusion cells or electron-beam evaporators until they begin to slowly sublime. The gaseous elements then condense on the wafer, where they may react with each other. In the example of gallium and arsenic, single-crystal gallium arsenide is formed. When evaporation sources such as copper or gold are used, the gaseous elements impinging on the surface may be adsorbed (after a time window where the impinging atoms will hop around the surface) or reflected. Atoms on the surface may also desorb. Controlling the temperature of the source will control the rate of material impinging on the substrate surface and the temperature of the substrate will affect the rate of hopping or desorption. The term \"beam\" means that evaporated atoms do not interact with each other or vacuum-chamber gases until they reach the wafer, due to the long mean free paths of the atoms. During operation, reflection high-energy electron diffraction (RHEED) is often used for monitoring the growth of the crystal layers. A computer controls shutters in front of each furnace, allowing precise control of the thickness of each layer, down to a single layer of atoms. Intricate structures of layers of different materials may be fabricated this way. Such control has allowed the development of structures where the electrons can be confined in space, giving quantum wells or even quantum dots. Such layers are now a critical part of many modern semiconductor devices, including semiconductor lasers and light-emitting diodes. In systems where the substrate needs to be cooled, the ultra-high vacuum environment within the growth chamber is maintained by a system of cryopumps and cryopanels, chilled using liquid nitrogen or cold nitrogen gas to a temperature close to 77 kelvins (−196 degree Celsius). Cold surfaces act as a sink for impurities in the vacuum, so vacuum levels need to be several orders of magnitude better to deposit films under these conditions. In other systems, the wafers on which the crystals are grown may be mounted on a rotating platter, which can be heated to several hundred degrees Celsius during operation. Molecular-beam epitaxy is also used for the deposition of some types of organic semiconductors. In this case, molecules, rather than atoms, are evaporated and deposited onto the wafer. Other variations include gas-source MBE, which resembles chemical vapor deposition. MBE systems can also be modified according to need. Oxygen sources, for example, can be incorporated for depositing oxide materials for advanced electronic, magnetic and optical applications, as well as for fundamental research.", "section_level": 1}, {"title": "Quantum nanostructures.", "content": "One of the most accomplished achievements of molecular-beam epitaxy is the nano-structures that permitted the formation of atomically flat and abrupt hetero-interfaces.

At some critical height, the free energy of the film can be lowered if the film breaks into isolated islands, where the tension can be relaxed laterally.

Conrad was marked out to act as regent for Germany, together with his elder brother, Duke Frederick II of Swabia. At the death of Henry V in 1125, Conrad unsuccessfully supported Frederick II for the kingship of Germany. Frederick was placed under a ban and Conrad was deprived of Franconia and the Kingdom of Burgundy, of which he was rector. With the support of the imperial cities, Swabia, and the Duchy of Austria, Conrad was elected anti-king at Nuremberg in December 1127. Conrad quickly crossed the Alps to be crowned King of Italy by Anselmo della Pusterla, Archbishop of Milan, in the village of Monza. Over the next two years, he failed to achieve anything in Italy, however, and returned to Germany in 1130, after Nuremberg and Speyer, two strong cities that supported him, fell to Lothair in 1129. Conrad continued in Lothair's opposition, but he and Frederick were forced to acknowledge Lothair as emperor in 1135, during which time Conrad relinquished his title as King of Italy. After this they were pardoned and could take again possession of their lands. After Lothair's death (December 1137), Conrad was elected king at Coblenz on 7 March 1138, in the presence of the papal legate Theodwin. Conrad was crowned at Aachen six days later (13 March) and was acknowledged in Bamberg by several princes of southern Germany. As Henry the Proud, son-in-law and heir of Lothair and the most powerful prince in Germany, who had been passed over in the election, refused to do the same, Conrad deprived him of all his territories, giving the Duchy of Saxony to Albert the Bear and that of Bavaria to Leopold IV, Margrave of Austria. Henry, however, retained the loyalty of his subjects. The civil war that broke out is considered the first act of the struggle between Guelphs and Ghibellines, which later extended southwards to Italy. After Henry's death (October 1139), the war was continued by his son Henry the Lion, supported by the Saxons, and by his brother Welf VI. Conrad, after a long siege, defeated the latter at Weinsberg in December 1140, and in May 1142 a peace agreement was reached in Frankfurt. In the same year, Conrad entered Bohemia to reinstate his brother-in-law Vladislav II as prince. The attempt to do the same with another brother-in-law, the Polish prince Ladislaus the Exile, failed. Bavaria, Saxony, and the other regions of Germany were in revolt. In 1146, Conrad heard Bernard of Clairvaux preach the Second Crusade at Speyer, and he agreed to join Louis VII in a great expedition to the Holy Land. At the imperial diet in Frankfurt in March 1147 Conrad and the assembled princes entrusted Bernard of Clairvaux with the recruitment for the Wendish crusade. Before leaving, he had the nobles elect and crown his son Henry Berengar king. The succession secured in the event of his death, Conrad set out. His army of 20,000 men went overland, via Hungary, causing disruptions in the Byzantine territories through which they passed. They arrived at Constantinople by September 1147, ahead of the French army. Rather than taking the coastal road around Anatolia through Christian-held territory, by which he sent most of his noncombatants, Conrad took his army across Anatolia. On 25 October 1147, they were defeated by the Seljuk Turks at the Battle of Dorylaeum. Conrad and most of the knights escaped, but most of the foot soldiers were killed or captured. The remaining 2,000 men of the German army limped on to Nicaea, where many of the survivors deserted and tried to return home. Conrad and his adherents had to be escorted to Lopadium by the French, where they joined the main French army under Louis. Conrad fell seriously ill at Ephesus and was sent to recuperate in Constantinople, where his host the Emperor Manuel I acted as his personal physician. After recovering, Conrad sailed to Acre, and from there reached Jerusalem. He participated in the ill-fated Siege of Damascus and after that failure, grew disaffected with his allies. Another attempt to attack Ascalon failed when Conrad's allies did not appear as promised, and Conrad returned to Germany. In 1150, Conrad and Henry Berengar defeated Welf VI and his son Welf VII at the Battle of Flochberg. Henry Berengar died later that year and the succession was thrown open. The Welfs and Hohenstaufen made peace in 1152 and the peaceful succession of one of Conrad's family was secured. Conrad was never crowned emperor and continued to style himself \"King of the Romans\" until his death. On his deathbed, in the presence of only two witnesses, his nephew Frederick Barbarossa and the Bishop of Bamberg, he allegedly designated Frederick his successor, rather than his own surviving six-year-old son Frederick. Frederick Barbarossa, who had accompanied his uncle on the unfortunate crusade, forcefully pursued his advantage and was duly elected king in Cologne a few weeks later. The young son of the late king was given the Duchy of Swabia. Conrad left no male heirs by his first wife, Gertrude von Komburg.

Many images seemingly depict structures very similar to \"audencias\" which indicates the cultural importance of architecture to the Chimú people of Chan Chan. Additionally, the construction of these massive architectural feats indicates that there was a large labor force available at Chan Chan. This further supports evidence for a hierarchical structure of society in Chan Chan as it was likely that the construction of this architecture was done by the working class. Chan Chan is triangular, surrounded by walls. There are no enclosures opening north because the north-facing walls have the greatest sun exposure, serving to block wind and absorb sunlight where fog is frequent. The tallest walls shelter against south-westerly winds from the coast. The walls are adobe brick covered with a smooth surface into which intricate designs are carved.

This title, though not acknowledged by Pope Gregory IX, presumed his future as a Holy Roman Emperor.

This exertion of power by the pope has since been regarded as a transition of power in the Holy Roman Empire. Notably, many bishops took this opportunity to gain more influence with their vast wealth and relative stability as opposed to the fractured monarchy which had proven to be somewhat unreliable.

This year Conrad issued constitutions during the hoftag in Foggia, which were based on the well-known examples from Norman and early Staufer times.

After the death of Frederick II, riots prevailed in parts of the kingdom of Sicily, and several cities attempted to escape the royal control. Conrad was therefore forced to take military action against the revolts. In October 1253 his troops conquered Naples.

The way in which he described the visit and its purpose is important; unlike all the others, Willibrord was not on the usual pilgrimage to the graves of the apostles Peter and Paul and the martyrs.

The second time he went to Rome, on 21 November 695, in the Church of Santa Cecilia in Trastevere, Pope Sergius I gave him a pallium and consecrated him as bishop of the Frisians. He returned to Frisia to preach and establish churches, among them a monastery at Utrecht, where he built his cathedral. Willibrord is counted the first Bishop of Utrecht. In 698 he established the Abbey of Echternach on the site of a Roman villa in Echternach, which was donated to him by Pepin's mother-in-law, Irmina of Oeren, the wife of seneschal and Count Palatine Hugobert. After Hugobert died, Irmina founded a Benedictine convent at Horren in Trier. When a plague threatened her community, she gained the help of Willibrord; and when the pestilence passed by the convent, she gave Willibrord the lands for his abbey in Echternach.

This youthful success, ambitious and monumental, was followed by a change in direction: for the next several years Géricault produced a series of small studies of horses and cavalrymen. He exhibited \"Wounded Cuirassier\" at the Salon in 1814, a work more labored and less well received. Géricault in a fit of disappointment entered the army and served for a time in the garrison of Versailles. In the nearly two years that followed the 1814 Salon, he also underwent a self-imposed study of figure construction and composition, all the while evidencing a personal predilection for drama and expressive force. A trip to Florence, Rome, and Naples (1816–17), prompted in part by the desire to flee from a romantic entanglement with his aunt, ignited a fascination with Michelangelo. Rome itself inspired the preparation of a monumental canvas, the \"Race of the Barberi Horses\", a work of epic composition and abstracted theme that promised to be \"entirely without parallel in its time\".

Perhaps his most significant, and certainly most ambitious work, is \"The Raft of the Medusa\" (1818–19), which depicted the aftermath of a contemporary French shipwreck, \"Meduse\", in which the captain had left the crew and passengers to die. The incident became a national scandal, and Géricault's dramatic interpretation presented a contemporary tragedy on a monumental scale. The painting's notoriety stemmed from its indictment of a corrupt establishment, but it also dramatized a more eternal theme, that of man's struggle with nature. It surely excited the imagination of the young Eugène Delacroix, who posed for one of the dying figures. The classical depiction of the figures and structure of the composition stand in contrast to the turbulence of the subject, so that the painting constitutes an important bridge between neo-classicism and romanticism. It fuses many influences: the \"Last Judgment\" of Michelangelo, the monumental approach to contemporary events by Antoine-Jean Gros, figure groupings by Henry Fuseli, and possibly the painting \"Watson and the Shark \"by John Singleton Copley. The painting ignited political controversy when first exhibited at the Paris Salon of 1819; it then traveled to England in 1820, accompanied by Géricault himself, where it received much praise.

The paintings are noteworthy for their bravura style, expressive realism, and for their documenting of the psychological discomfort of individuals, made all the more poignant by the history of insanity in Géricault's family, as well as the artist's own fragile mental health. His observations of the human subject were not confined to the living, for some remarkable still-lifes—painted studies of severed heads and limbs—have also been ascribed to the artist.

The left-wing attempted to retaliate, but were outgunned by the British-backed government and subjected to the White Terror. With the full outbreak of civil war (1946–49), guerrilla forces controlled by the Greek Communist Party sustained a revolt against the internationally recognized Greek government which was formed after 1946 elections boycotted by the KKE. The British realized that the KKE were being directly funded by Josip Broz Tito in neighboring Yugoslavia. In line with the Churchill-Stalin \"percentages agreement\", the Greek communists received no help from the Soviet Union, and Yugoslavia provided them support and sanctuary against Stalin's wishes. By late 1946, Britain informed the United States that due to its own weakening economy, it could no longer continue to provide military and economic support to royalist Greece. In 1946–47, the United States and the Soviet Union moved from being wartime allies to Cold War adversaries. The breakdown of Allied cooperation in Germany provided a backdrop of escalating tensions for the Truman Doctrine. To Truman, the growing unrest in Greece began to look like a pincer movement against the oil-rich areas of the Middle East and the warm-water ports of the Mediterranean. In February 1946, Kennan, an American diplomat in Moscow, sent his famed \"Long Telegram\", which predicted the Soviets would only respond to force and that the best way to handle them would be through a long-term strategy of containment, that is stopping their geographical expansion. After the British warned that they could no longer help Greece, and following Prime Minister Konstantinos Tsaldaris's visit to Washington in December 1946 to ask for American assistance, the U.S. State Department formulated a plan. Aid would be given to both Greece and Turkey, to help cool the long-standing rivalry between them. American policy makers recognized the instability of the region, fearing that if Greece was lost to communism, Turkey would not last long. Similarly, if Turkey yielded to Soviet demands, the position of Greece would be endangered. A regional domino effect threat therefore guided the American decision.

The chief Republican spokesman Senator Arthur H. Vandenberg strongly supported Truman and overcame the doubts of isolationists such as Senator Robert A. Taft. Truman laid the groundwork for his request by having key congressional leaders meet with himself, Secretary of State George Marshall, and Undersecretary of State Dean Acheson. Acheson laid out the \"domino theory\" in the starkest terms, comparing a communist state to a rotten apple that could spread its infection to an entire barrel. Vandenberg was impressed, and advised Truman to appear before Congress and \"scare the hell out of the American people.\" On March 7, Acheson warned Truman that Greece could fall to the communists within weeks without outside aid. When a draft for Truman's address was circulated to policymakers, Marshall, Kennan, and others criticized it for containing excess \"rhetoric.\" Truman responded that, as Vandenberg had suggested, his request would only be approved if he played up the threat. On March 12, 1947, Truman appeared before a joint session of Congress. In his eighteen-minute speech, he stated: The reaction to Truman's speech was broadly positive, though there were dissenters. Anti-communists in both parties supported both Truman's proposed aid package and the doctrine behind it, and \"Collier's\" described it as a \"popularity jackpot\" for the President. Influential columnist Walter Lippmann was more skeptical, noting the open-ended nature of Truman's pledge; he felt so strongly that he almost came to blows while arguing with Acheson over the doctrine. Others argued that the Greek monarchy Truman proposed to defend was itself a repressive government, rather than a democracy. Despite these objections, the fear of the growing communist threat almost guaranteed the bill's passage. In May 1947, two months after Truman's request, a large majority of Congress approved $400 million in military and economic aid to Greece and Turkey. Increased American aid helped defeat the KKE, after interim defeats for government forces from 1946 to 1948.

Its sweeping rhetoric, promising that the United States should aid all 'free people' being subjugated, set the stage for innumerable later ventures that led to globalisation commitments. It was in these ways a major step.\" The doctrine endured, historian Dennis Merill argues, because it addressed broader cultural insecurity regarding modern life in a globalized world. It dealt with Washington's concern over communism's domino effect, it enabled a media-sensitive presentation of the doctrine that won bipartisan support, and it mobilized American economic power to modernize and stabilize unstable regions without direct military intervention. It brought nation-building activities and modernization programs to the forefront of foreign policy. The Truman Doctrine became a metaphor for aid to keep a nation from communist influence. Truman used disease imagery not only to communicate a sense of impending disaster in the spread of communism but also to create a \"rhetorical vision\" of containing it by extending a protective shield around non-communist countries throughout the world. It echoed the \"quarantine the aggressor\" policy Truman's predecessor, Franklin D. Roosevelt, had sought to impose to contain German and Japanese expansion in 1937 (\"quarantine\" suggested the role of public health officials handling an infectious disease). The medical metaphor extended beyond the immediate aims of the Truman Doctrine in that the imagery combined with fire and flood imagery evocative of disaster provided the United States with an easy transition to direct military confrontation in later years with the Korean War and the Vietnam War.

The Reynolds number is the ratio of the inertial force to the shearing force of the fluid: how fast the fluid is moving relative to how viscous it is, irrespective of the scale of the fluid system. Laminar flow generally occurs when the fluid is moving slowly or the fluid is very viscous. As the Reynolds number increases, such as by increasing the flow rate of the fluid, the flow will transition from laminar to turbulent flow at a specific range of Reynolds numbers, the laminar–turbulent transition range depending on small disturbance levels in the fluid or imperfections in the flow system. If the Reynolds number is very small, much less than 1, then the fluid will exhibit Stokes, or creeping, flow, where the viscous forces of the fluid dominate the inertial forces.

Behavioral therapy — in which a person systematically asks his own mind if the doubt has any real basis — uses rational, Socratic methods.

Alternatively, doubt over the existence of god(s) may lead to acceptance of a particular religion: compare Pascal's Wager. Doubt of a specific theology, scriptural or deistic, may bring into question the truth of that theology's set of beliefs. On the other hand, doubt as to some doctrines but acceptance of others may lead to the growth of heresy and/or the splitting off of sects or groups of thought. Thus proto-Protestants doubted papal authority, and substituted alternative methods of governance in their new (but still recognizably similar) churches. Christianity often debates doubt in the contexts of salvation and eventual redemption in an afterlife. This issue has become particularly important in Protestantism, which requires \"only\" the acceptance of Jesus, though more contemporary versions have arisen within the Protestant churches that resemble Catholicism. Doubt as a path towards (deeper) belief lies at the heart of the story of Saint Thomas the Apostle. Note in this respect the theological views of Georg Hermes:... the starting-point and chief principle of every science, and hence of theology also, is not only methodical doubt, but positive doubt. One can believe only what one has perceived to be true from reasonable grounds, and consequently one must have the courage to continue doubting until one has found reliable grounds to satisfy the reason. Christian existentialists such as Søren Kierkegaard suggest that for one to truly have belief in God, one would also have to doubt one's beliefs about God; the doubt is the rational part of a person's thought involved in weighing evidence, without which the belief would have no real substance. Belief is not a decision based on evidence that, say, certain beliefs about God are true or a certain person is worthy of love. No such evidence could ever be enough to pragmatically justify the kind of total commitment involved in true theological belief or romantic love. Belief involves making that commitment anyway.

It carries its own origin of replication, the \"oriV\", and an origin of transfer, or \"oriT\". There can only be one copy of the F-plasmid in a given bacterium, either free or integrated, and bacteria that possess a copy are called \"F-positive\" or \"F-plus\" (denoted F). Cells that lack F plasmids are called \"F-negative\" or \"F-minus\" (F) and as such can function as recipient cells. Among other genetic information, the F-plasmid carries a \"tra\" and \"trb\" locus, which together are about 33 kb long and consist of about 40 genes. The \"tra\" locus includes the \"pilin\" gene and regulatory genes, which together form pili on the cell surface. The locus also includes the genes for the proteins that attach themselves to the surface of F bacteria and initiate conjugation. Though there is some debate on the exact mechanism of conjugation it seems that the pili are not the structures through which DNA exchange occurs. This has been shown in experiments where the pilus are allowed to make contact, but then are denatured with SDS and yet DNA transformation still proceeds. Several proteins coded for in the \"tra\" or \"trb\" locus seem to open a channel between the bacteria and it is thought that the traD enzyme, located at the base of the pilus, initiates membrane fusion. When conjugation is initiated by a signal the relaxase enzyme creates a nick in one of the strands of the conjugative plasmid at the \"oriT\". Relaxase may work alone or in a complex of over a dozen proteins known collectively as a relaxosome. In the F-plasmid system the relaxase enzyme is called TraI and the relaxosome consists of TraI, TraY, TraM and the integrated host factor IHF. The nicked strand, or \"T-strand\", is then unwound from the unbroken strand and transferred to the recipient cell in a 5'-terminus to 3'-terminus direction. The remaining strand is replicated either independent of conjugative action (vegetative replication beginning at the \"oriV\") or in concert with conjugation (conjugative replication similar to the rolling circle replication of lambda phage). Conjugative replication may require a second nick before successful transfer can occur. A recent report claims to have inhibited conjugation with chemicals that mimic an intermediate step of this second nicking event. If the F-plasmid that is transferred has previously been integrated into the donor's genome (producing an Hfr strain [\"High Frequency of Recombination\"]) some of the donor's chromosomal DNA may also be transferred with the plasmid DNA. The amount of chromosomal DNA that is transferred depends on how long the two conjugating bacteria remain in contact. In common laboratory strains of \"E. coli\" the transfer of the entire bacterial chromosome takes about 100 minutes. The transferred DNA can then be integrated into the recipient genome via homologous recombination. A cell culture that contains in its population cells with non-integrated F-plasmids usually also contains a few cells that have accidentally integrated their plasmids. It is these cells that are responsible for the low-frequency chromosomal gene transfers that occur in such cultures. Some strains of bacteria with an integrated F-plasmid can be isolated and grown in pure culture. Because such strains transfer chromosomal genes very efficiently they are called Hfr (high frequency of recombination). The \"E. coli\" genome was originally mapped by interrupted mating experiments in which various Hfr cells in the process of conjugation were sheared from recipients after less than 100 minutes (initially using a Waring blender). The genes that were transferred were then investigated. Since integration of the F-plasmid into the \"E. coli\" chromosome is a rare spontaneous occurrence, and since the numerous genes promoting DNA transfer are in the plasmid genome rather than in the bacterial genome, it has been argued that conjugative bacterial gene transfer, as it occurs in the \"E. coli\" Hfr system, is not an evolutionary adaptation of the bacterial host, nor is it likely ancestral to eukaryotic sex. Spontaneous zygogenesis in \"E. coli\" In addition to classical bacterial conjugation described above for \"E. coli\", a form of conjugation referred to as spontaneous zygogenesis (Z-mating for short) is observed in certain strains of \"E. coli\".

Furthermore, in contrast to \"E. coli\" Hfr conjugation, in \"M. smegmatis\" all regions of the chromosome are transferred with comparable efficiencies. The lengths of the donor segments vary widely, but have an average length of 44.2kb. Since a mean of 13 tracts are transferred, the average total of transferred DNA per genome is 575kb.

Infected cells form crown gall or root tumors. The Ti and Ri plasmids are thus endosymbionts of the bacteria, which are in turn endosymbionts (or parasites) of the infected plant.

The similar word \"ecclesialogy \"first appeared in the quarterly journal \"The British Critic\" in 1837, in an article written by an anonymous contributor who defined it thus: However, in volume 4 of the Cambridge Camden Society's journal \"The Ecclesiologist\", published in January 1845 that society (the CCS) claimed that they had invented the word \"ecclesiology\": \"The Ecclesiologist\" was first published in October 1841 and dealt with the study of the building and decoration of churches.

Its successor \"Ecclesiology Today\" is still,, being published by The Ecclesiological Society (successor to the CCS, now a registered charity). The situation regarding the etymology has been summed up by Alister McGrath: \"'Ecclesiology' is a term that has changed its meaning in recent theology.

This shift is most clearly marked by the encyclical \"Divino afflante Spiritu\" in 1943. Avery Robert Cardinal Dulles, S.J. contributed greatly to the use of models in understanding ecclesiology. In his work Models of the Church, he defines five basic models of Church that have been prevalent throughout the history of the Catholic Church. These include models of the Church as institution, as mystical communion, as sacrament, as herald, and as servant. The ecclesiological model of Church as an Institution holds that the Catholic Church alone is the \"one, holy, catholic and apostolic Church\", and is the only Church of divine and apostolic origin led by the Pope. This view of the Church is dogmatically defined Catholic doctrine, and is therefore \"de fide\". In this view, the Catholic Church— composed of all baptized, professing Catholics, both clergy and laity—is the unified, visible society founded by Christ himself, and its hierarchy derives its spiritual authority through the centuries, via apostolic succession of its bishops, most especially through the bishop of Rome (the Pope) whose successorship comes from St. Peter the Apostle, to whom Christ gave \"the keys to the Kingdom of Heaven\". Thus, the Popes, in the Catholic view, have a God-ordained universal jurisdiction over the whole Church on earth. The Catholic Church is considered Christ's mystical body, and the universal sacrament of salvation, whereby Christ enables human to receive sanctifying grace. The model of Church as Mystical Communion draws on two major Biblical images, the first of the \"Mystical Body of Christ\" (as developed in Paul's Epistles) and the second of the \"People of God.\" This image goes beyond the Aristotelian-Scholastic model of \"\"Communitas Perfecta\"\" held in previous centuries. This ecclesiological model draws upon sociology and articulations of two types of social relationships: a formally organized or structured society (Gesellschaft) and an informal or interpersonal community (Gemeinschaft). The Catholic theologian Arnold Rademacher maintained that the Church in its inner core is community (Gemeinschaft) and in its outer core society (Gesellschaft). Here, the interpersonal aspect of the Church is given primacy and that the structured Church is the result of a real community of believers. Similarly, Yves Congar argued that the ultimate reality of the Church is a fellowship of persons. This ecclesiology opens itself to ecumenism and was the prevailing model used by the Second Vatican Council in its ecumenical efforts. The Council, using this model, recognized in its document \"Lumen gentium\" that the Body of Christ subsists in a visible society governed by the Successor of Peter and by the Bishops in communion with him, although many elements of sanctification and of truth are found outside its visible structure.", "section_level": 1}, {"title": "Eastern Orthodox ecclesiology.", "content": "From the Eastern Orthodox perspective, the Church is one, even though it is manifested in many places.

In this view, it is both canonically and theologically correct to speak of the Church and the churches, and vice versa. Historically, that ecclesiological concept was applied in practice as patriarchal pentarchy, embodied in ecclesiastical unity of five major patriarchal thrones (Rome, Constantinople, Alexandria, Antioch and Jerusalem).

Sullivan Palincsar. Psychological tools are one of the key concepts in Lev Vygotsky's sociocultural perspective. Studies on increasing the use of student discussion in the classroom both support and are grounded in theories of social constructivism. There is a full range of advantages that results from the implementation of discussion in the classroom. Participating in group discussion allows students to generalize and transfer their knowledge of classroom learning and builds a strong foundation for communicating ideas orally. Many studies argue that discussion plays a vital role in increasing student ability to test their ideas, synthesize the ideas of others, and build deeper understanding of what they are learning. Large and small group discussion also affords students opportunities to exercise self-regulation, self-determination, and a desire to persevere with tasks. Additionally, discussion increases student motivation, collaborative skills, and the ability to problem solve. Increasing students’ opportunity to talk with one another and discuss their ideas increases their ability to support their thinking, develop reasoning skills, and to argue their opinions persuasively and respectfully. Furthermore, the feeling of community and collaboration in classrooms increases through offering more chances for students to talk together. Studies have found that students are not regularly accustomed to participating in academic discourse. Martin Nystrand argues that teachers rarely choose classroom discussion as an instructional format. The results of Nystrand’s (1996) three-year study focusing on 2400 students in 60 different classrooms indicate that the typical classroom teacher spends under three minutes an hour allowing students to talk about ideas with one another and the teacher. Even within those three minutes of discussion, most talk is not true discussion because it depends upon teacher-directed questions with predetermined answers. Multiple observations indicate that students in low socioeconomic schools and lower track classrooms are allowed even fewer opportunities for discussion. Teachers who teach as if they value what their students think create learners. Discussion and interactive discourse promote learning because they afford students the opportunity to use language as a demonstration of their independent thoughts. Discussion elicits sustained responses from students that encourage meaning-making through negotiating with the ideas of others.

Polycarbonate is highly transparent to visible light, with better light transmission than many kinds of glass. Polycarbonate has a glass transition temperature of about, so it softens gradually above this point and flows above about. Tools must be held at high temperatures, generally above to make strain-free and stress-free products. Low molecular mass grades are easier to mold than higher grades, but their strength is lower as a result. The toughest grades have the highest molecular mass, but are much more difficult to process. Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as bending on a brake. Even for sharp angle bends with a tight radius, heating may not be necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be made from sheet metal.

Humans and other animals must ingest histidine or histidine-containing proteins. The biosynthesis of histidine has been widely studied in prokaryotes such as \"E. coli\".

This is possible because a single gene product has the ability to catalyze more than one reaction. For example, as shown in the pathway, His4 catalyzes 4 different steps in the pathway. Histidine is synthesized from phosphoribosyl pyrophosphate (PRPP), which is made from ribose-5-phosphate by ribose-phosphate diphosphokinase in the pentose phosphate pathway. The first reaction of histidine biosynthesis is the condensation of PRPP and adenosine triphosphate (ATP) by the enzyme ATP-phosphoribosyl transferase. ATP-phosphoribosyl transferase is indicated by His1 in the image. His4 gene product then hydrolyzes the product of the condensation, phosphoribosyl-ATP, producing phosphoribosyl-AMP (PRAMP), which is an irreversible step. His4 then catalyzes the formation of phosphoribosylformiminoAICAR-phosphate, which is then converted to phosphoribulosylformimino-AICAR-P by the His6 gene product. His7 splits phosphoribulosylformimino-AICAR-P to form -erythro-imidazole-glycerol-phosphate. After, His3 forms imidazole acetol-phosphate releasing water. His5 then makes -histidinol-phosphate, which is then hydrolyzed by His2 making histidinol. His4 catalyzes the oxidation of -histidinol to form -histidinal, an amino aldehyde. In the last step, -histidinal is converted to -histidine. Just like animals and microorganisms, plants need histidine for their growth and development.

King Conrad died in February 1152 and a few weeks later his nephew Frederick was elected King of the Romans, probably with the support of late Henry the Proud's son Henry the Lion. The young king and Henry the Lion were cousins through Frederick's mother Judith of Bavaria, sister of Henry the Proud. Frederick prepared for a campaign to Rome to be crowned Holy Roman Emperor and in order to gain military support wished to end the conflict he had inherited from his uncle. He called for a diet at Würzburg —however, Henry Jasomirgott, who anticipated the king's intentions, did not appear under the pretext, that he had not been duly summoned. After several attempts to make an arrangement, Frederick left for Italy and was crowned Emperor on 18 June 1155. Back in Germany, Frederick resolved upon returning the Duchy of Bavaria to Henry the Lion. He finally was able to hold a secret meeting with Henry Jasomirgott on 5 June 1156 near the Bavarian capital Regensburg. After the conditions were fixed, the emperor called for another diet in Regensburg on 8 September, where the Babenberger officially renounced the Bavarian duchy, which passed to the Welf Henry the Lion. To make up for the loss, Austria with the explicit consent by the Princes of the Holy Roman Empire, led by Duke Vladislaus II of Bohemia, was raised to the status of a duchy. Frederick thereby avoided the degradation of Henry Jasomirgott to the rank of a margrave, which would have lacked any explanation and furthermore would have exposed Henry Jasomirgott to persecution by the Welfs.

Down to the time of Constantine, who deprived the office of its military character, the prefecture of the guards was regularly held by tried soldiers, often by men who had fought their way up from the ranks. In course of time the command seems to have been enlarged so as to include all the troops in Italy except the corps commanded by the city praefect (\"cohortes urbanae\"). The special position of the praetorians made them a power in their own right in the Roman state, and their prefect, the \"praefectus praetorio\", soon became one of the more powerful men in this society. The emperors tried to flatter and control the praetorians, but they staged many coups d'état and contributed to a rapid rate of turnover in the imperial succession. The praetorians thus came to destabilize the Roman state, contrary to their purpose. The praetorian prefect became a major administrative figure in the later empire, when the post combined in one individual the duties of an imperial chief of staff with direct command over the guard also.

The prefect remained as chief quarter-master general responsible for the logistical supply of the army. The prefect was the chief financial officer whose office drew up the global imperial budget. His office drew up the state liturgical obligations laid on the richer inhabitants of the Empire. He ceased to be head of administration which had to be shared with the master of the offices attached to the palace. Constantine in 331 confirmed that from the sentence of the praetorian praefect there should be no appeal. A similar jurisdiction in civil cases was acquired by him not later than the time of Septimius Severus. Hence a knowledge of law became a qualification for the post, which under Marcus Aurelius and Commodus, but especially from the time of Severus, was held by the first jurists of the age, (e.g. Papinian, Ulpian, Paulus) and, under Justinianus, John the Cappadocian, while the military qualification fell more and more into the background.

In the midsummer, individuals begin foraging at sunset, continuing throughout the night, and fading into the early morning. Foraging is almost exclusively diurnal during the winter it usually occurs in patches, which match the clumped prey resources, such as termite colonies, that also occur in patches.

They often live in pairs or groups of up to 15 individuals, and home ranges of groups either overlap substantially or very little. Individuals forage, play, and rest together in a group, which helps in protection against predators. Social grooming occurs throughout the year, mostly between mature adults, but also between young adults and mature adults. Visual displays are very important in communication among bat-eared foxes. When they are looking intently at something, the head is held high, eyes are open, ears are erect and facing forward, and the mouth is closed. When an individual is in threat or showing submission, the ears are pulled back and lying against the head and the head is low. The tail also plays a role in communication. When an individual is asserting dominance or aggression, feeling threatened, playing, or being sexually aroused, the tail is arched in an inverted U shape. Individuals can also use piloerection, which occurs when individual hairs are standing straight, to make it appear larger when faced with extreme threat. When running, chasing, or fleeing, the tail is straight and horizontal. The bat-eared fox can recognize individuals up to 30 m away. The recognition process has three steps: First they ignore the individual, then they stare intently, and finally they either approach or attack without displays. When greeting another, the approaching individual shows symbolic submission which is received by the other individual with a high head and tail down.

The concept has also been identified in classical Greek drama, Roman satire, and Renaissance literature such as \"Don Quixote\" and the picaresque rogue. The term antihero was first used as early as 1714, emerging in works such as \"Rameau's Nephew\" in the 18th century, and is also used more broadly to cover Byronic heroes as well. Literary Romanticism in the 19th century helped popularize new forms of the antihero, such as the Gothic double. The antihero eventually became an established form of social criticism, a phenomenon often associated with the unnamed protagonist in Fyodor Dostoyevsky's \"Notes from Underground.\" The antihero emerged as a foil to the traditional hero archetype, a process that Northrop Frye called the fictional \"center of gravity\". This movement indicated a literary change in heroic ethos from feudal aristocrat to urban democrat, as was the shift from epic to ironic narratives. Huckleberry Finn (1884) has been called \"the first antihero in the American nursery\". Charlotte Mullen of Somerville and Ross' \"The Real Charlotte\" (1894) has been described as an antiheroine. The antihero became prominent in early 20th century existentialist works such as Franz Kafka's \"The Metamorphosis\" (1915), Jean-Paul Sartre's \"La Nausée\" (1938) (), and Albert Camus' \"L'Étranger\" (1942) (). The protagonist in these works is an indecisive central character who drifts through his life and is marked by ennui, angst, and alienation. The antihero entered American literature in the 1950s and up to the mid-1960s was portrayed as an alienated figure, unable to communicate. The American antihero of the 1950s and 1960s (as seen in the works of Jack Kerouac, Norman Mailer, et al.) was typically more proactive than his French counterpart, with characters such as Kerouac's Dean Moriarty famously taking to the road to vanquish his ennui. The British version of the antihero emerged in the works of the \"angry young men\" of the 1950s. The collective protests of Sixties counterculture saw the solitary antihero gradually eclipsed from fictional prominence, though not without subsequent revivals in literary and cinematic form. The antihero also plays a prominent role in films noir such as \"Double Indemnity\" (1944) and \"Night and the City\" (1950), in gangster films such as \"The Godfather\" (1972), and in Western films, especially the Revisionist Western and Spaghetti Western. Lead figures in these westerns are often morally ambiguous, such as the \"Man with No Name\", portrayed by Clint Eastwood in \"A Fistful of Dollars\" (1964), \"For a Few Dollars More\" (1965) and \"The Good, the Bad and the Ugly\" (1966).

His transcriptions were especially useful to Grotefend, who made the first correct decirpherments of Old Persian cuneiform: He also visited the ruins of Babylon (making many important sketches), Baghdad, Mosul and Aleppo. He seems also to have visited the Behistun Inscription in around 1764. After a visit to Cyprus he made a tour through Palestine, crossed the Taurus Mountains to Bursa, reached Constantinople in February 1767 and finally arrived in Copenhagen in the following November. Niebuhr's production during the expedition is indeed impressive. It includes small-scale maps and charts of Yemen, the Red Sea, the Persian Gulf and Oman, and other larger scale maps covering the Nile Delta, the Gulf of Suez and the regions surrounding various port cities he visited, including Mocha and Surat. He completed 28 town plans of significant historical value because of their uniqueness for that period.

This was followed in 1774 and 1778 by the first two volumes of Niebuhr's \"Reisebeschreibung nach Arabien und andern umliegender Ländern\". These works (particularly the one published in 1778), and most specifically the accurate copies of the cuneiform inscriptions found at Persepolis, were to prove to be extremely important to the decipherment of cuneiform writing. Before Niebuhr's publication, cuneiform inscriptions were often thought to be merely decorations and embellishments, and no accurate decipherments or translations had been made up to that point. Niebuhr demonstrated that the three trilingual inscriptions found at Persepolis were in fact three distinct forms of cuneiform writing (which he termed Class I, Class II, and Class III) to be read from left to right. His accurate copies of the trilingual inscriptions gave Orientalists the key to finally crack the cuneiform code, leading to the discovery of Old Persian, Akkadian, and Sumerian. The third volume of the Reisebeschreibung, also based on materials from the expedition, was not published till 1837, long after Niebuhr's death, under the editorship of his daughter and his assistant, Johan Nicolaus Gloyer. Niebuhr also contributed papers on the interior of Africa, the political and military condition of the Ottoman Empire, and other subjects to a German periodical, the \"Deutsches Museum\". In addition, he edited and published the work of his friend Peter Forsskål, the naturalist on the Arabian expedition, under the titles \"Descriptiones animalium, Flora Aegyptiaco-Arabica\" and \"Icones rerum naturalium\" (Copenhagen, 1775 and 1776). French and Dutch translations of Niebuhr's narratives were published during his lifetime, and a condensed English translation of his own three volumes, prepared by Robert Heron, was published in Edinburgh in 1792, under the title \"Travels through Arabia\". A facsimile edition of this translation, as by \"M. Niebuhr\", was published in two volumes by the Libraire du Liban, Beirut (undated). The government funds covered only a fraction of the printing costs for Niebuhr's first book, and probably a similar or smaller proportion of the costs for the other two volumes. To ensure that the volumes were published, Niebuhr had to pay over 80% of the costs himself. In all, Niebuhr devoted ten years of his life, the years 1768-1778, to the publication of six volumes of findings from the expedition. He had virtually no help from the academics who had conceived and shaped the expedition in Göttingen and Copenhagen.

Most collections are of manufactured commercial items, but natural objects such as birds' eggs, butterflies, rocks, and seashells can also be the subject of a collection. For some collectors, the criterion for inclusion might not be the type of object but some incidental property such as the identity of its original owner. Some collectors are generalists with very broad criteria for inclusion, while others focus on a subtopic within their area of interest. Some collectors accumulate arbitrarily many objects that meet the thematic and quality requirements of their collection, others—called \"completists\" or \"completionists\"—aim to acquire all items in a well-defined set that can in principle be completed, and others seek a limited number of items per category (e.g. one representative item per year of manufacture or place of purchase).

There is no secondary market for an item unless someone is willing to buy it, and an object's value is whatever the buyer is willing to pay. Depending on age, condition, supply, demand, and other factors, individuals, auctioneers, and secondary retailers may sell a collectable for either more or less than what they originally paid for it. Special or limited edition collectables are created with the goal of increasing demand and value of an item due to its rarity. A \"price guide\" is a resource such as a book or website that lists typical selling prices. Products often become more valuable with age. The term \"antique\" generally refers to manufactured items made over 100 years ago, although in some fields, such as antique cars, the time frame is less stringent. For antique furniture, the limit has traditionally been set in the 1830s. Collectors and dealers may use the word \"vintage\" to describe older collectables that are too young to be called antiques, including Art Deco and Art Nouveau items, Carnival and Depression glass, etc. Items which were once everyday objects but may now be collectable, as almost all examples produced have been destroyed or discarded, are called \"ephemera\".", "section_level": 1}, {"title": "Psychological aspects.", "content": "Psychological factors can play a role in both the motivation for keeping a collection and the impact it has on the collector's life. These factors can be positive or negative. The hobby of collecting often goes hand-in-hand with an interest in the objects collected and what they represent, for example collecting postcards may reflect an interest in different places and cultures. For this reason, collecting can have educational benefits, and some collectors even become experts in their field. Maintaining a collection can be a relaxing activity that counteracts the stress of life, while providing a purposeful pursuit which prevents boredom. The hobby can lead to social connections between people with similar interests and the development of new friendships. It has also been shown to be particularly common among academics. Collecting for most people is a choice, but for some it can be a compulsion, sharing characteristics with obsessive hoarding. When collecting is passed between generations, it might sometimes be that children have inherited symptoms of obsessive–compulsive disorder. Collecting can sometimes reflect a fear of scarcity, or of discarding something then later regretting it. It has been speculated that the widespread appeal of collecting is connected to the hunting and gathering that was once necessary for human survival.

In Mesopotamia, collecting practices have been noted among royalty and elites as far back as the 3rd millennium BCE.

The Medici family, in Renaissance Florence, made the first effort to collect art by private patronage, this way artists could be free for the first time from the money given by the Church and Kings; this citizenship tradition continues today with the work of private art collectors. Many of the world's popular museums—from the Metropolitan in New York City to the Thyssen in Madrid or the Franz Mayer in Mexico City—have collections formed by the collectors that donated them to be seen by the general public. The collecting hobby is a modern descendant of the \"cabinet of curiosities\" which was common among scholars with the means and opportunities to acquire unusual items from the 16th century onwards. Planned collecting of ephemeral publications goes back at least to George Thomason in the reign of Charles I and Samuel Pepys in that of Charles II. Collecting engravings and other prints by those whose means did not allow them to buy original works of art also goes back many centuries. The progress in 18th-century Paris of collecting both works of art and of \"curiosité\", dimly echoed in the English \"curios\", and the origins in Paris, Amsterdam and London of the modern art market have been increasingly well documented and studied since the mid-19th century. The involvement of larger numbers of people in collecting activities came with the prosperity and increased leisure for some in the later 19th century in industrial countries.

Just before his birth, his father had achieved the elevation of the Austrian margraviate to a duchy according to the 1156 \"Privilegium Minus\", issued by Emperor Frederick Barbarossa. As the eldest son of Henry II, Leopold was already enfeoffed with the Austrian duchy by the emperor in the summer of 1174 at Regensburg. He succeeded his father as Duke of Austria upon his death on 13 January 1177. Soon after, Leopold lent his support to Duke Frederick of Bohemia stuck in a conflict with his Přemyslid cousin Soběslav II, who had campaigned in the Austrian duchy. In turn, Leopold reached a peace agreement with the neighbouring Duchy of Bohemia, determined by Emperor Frederick Barbarossa at Eger in 1179. Two years later, he attended an Imperial Diet in Erfurt, where his first-born son Frederick was enfeoffed with the Austrian estate. In 1182 Leopold went on a pilgrimage to the Holy Land and was received with honour at the courts of King Béla III of Hungary and of Emperor Alexios II Komnenos in Constantinople. Back in Germany, he began negotiating the Georgenberg Pact with the last Otakar duke Ottokar IV of Styria, who had received the ducal title from Emperor Frederick in 1180. The agreement was concluded on 17 August 1186, whereafter Styria and the central part of Upper Austria with Wels and Steyr were amalgamated into the Duchy of Austria upon Ottokar's death in 1192. The next year Leopold was enfeoffed with Styria by the emperor; this was the first step towards the creation of modern Austria. Leopold is mainly remembered outside Austria for his participation in the Third Crusade. Border disputes with King Béla III of Hungary had initially impeded the duke from accompanying Emperor Frederick on his departure in May 1189. When he heard about the emperor's death in 1190, he went to Venice, where he embarked to the Holy Land. Autumn storms forced him to winter in Zadar on the Adriatic coast. He arrived in Palestine to take part in the final stage of the Siege of Acre in spring 1191. Leopold assumed command of the remnants of the Imperial forces after the death of the emperor's son Duke Frederick of Swabia in January. According to legend, his tunic was blood-soaked after the fights. When he doffed his belt, a white stripe appeared. The new emperor Henry VI granted him the privilege to adopt these colours as his new banner, that later would become the flag of Austria. Acre surrendered on July 12, after the arrival of King Philip II of France and King Richard I of England. Duke Leopold, as commander of the German contingent, demanded rights equal to those of the two kings but was rejected. When the banners of the Kingdom of Jerusalem, England, France and Leopold's ducal flag were raised in the city by Leopold's cousin, Marquis Conrad of Montferrat, Richard removed Leopold's colours (see Siege of Acre) and the duke wrathfully left for his Austrian home, where he arrived by the end of 1191. In January 1192 he proceeded to the court of Emperor Henry VI and complained bitterly about Richard, who also was suspected of involvement in the murder of Conrad, shortly after his election as King of Jerusalem in April. The emperor probably agreed with King Philip, already in conflict with the English king, on Richard's capture. When Richard left the Holy Land in late October 1192, he found the French ports closed and sailed up the Adriatic Sea. He took the country road from Aquileia across Austria, to reach the Bavarian estates of his Welf brother-in-law Henry the Lion. Whilst travelling under disguise, he stopped at Vienna shortly before Christmas 1192, where he was recognized (supposedly because of his signet ring) and arrested in Erdberg (modern Landstraße district). Initially Duke Leopold had the king imprisoned in Dürnstein, and in March 1193 Richard was brought before Emperor Henry VI at Trifels Castle, accused of Conrad's murder. A ransom of 35,000 kilograms of silver was paid to release King Richard. Leopold demanded that Richard's niece, Eleanor, marry his son Frederick. Due to Leopold's death, this marriage never took place. Leopold's share of the ransom became the foundation for the mint in Vienna, and was used to build new city walls for Vienna, as well as to found the towns of Wiener Neustadt and Friedberg in Styria. The duke was excommunicated by Pope Celestine III for having taken a fellow crusader prisoner. To receive absolution, Leopold prepared for another crusade, but this plan failed. In 1194, his foot was crushed when his horse fell on him at a tournament in Graz. Though advised by his surgeons to have the foot amputated, no one admitted to being able to do it. He ordered his servants to chop his foot off with an axe, which they succeeded in doing after three swings. He succumbed to gangrene.

The Greek settlement was begun as a failed colony from Klazomenai, traditionally dated to 654. (Evidence in 7th-century- Greek pottery tends to support the traditional date but the exact timing remains uncertain.) Herodotus reports that the leader of the colony had been Timesios but, within his generation, the Thracians had expelled the colonists. Timesios was subsequently honored as a local protective spirit by the later Abderans from Teos. Others recount various legends about this colony. Plutarch and Aelian relate that Timesios grew insufferable to his colonists because of his desire to do everything by himself; when one of their children let him know how they all really felt, he quit the settlement in disgust; modern scholars have tried to split the difference between the two accounts of early Abdera's failure by giving the latter as the reason for Timesios's having left Klazomenai. The successful foundation occurred in 544BC, when the majority of the people of Teos (including the poet Anacreon) migrated to Abdera to escape the Persian yoke. The chief coin type, a \"griffon\", is identical with that of Teos; the rich silver coinage is noted for the beauty and variety of its reverse types. In 513 and 512, the Persians, under Darius conquered Abdera, by which time the city seems to have become a place of considerable importance, and is mentioned as one of the cities which had the expensive honour of entertaining the great king on his march into Greece. In 492, after the Ionian Revolt, the Persians again conquered Abdera, again under Darius I but led by his general Mardonius. On his flight after the Battle of Salamis, Xerxes stopped at Abdera and acknowledged the hospitality of its inhabitants by presenting them with a tiara and scimitar of gold. Thucydides mentions Abdera as the westernmost limit of the Odrysian kingdom when at its height at the beginning of the Peloponnesian war. It later became part of the Delian League and fought on the side of Athens in the Peloponnesian war. Abdera was a wealthy city, the third richest in the League, due to its status as a prime port for trade with the interior of Thrace and the Odrysian kingdom. In 408, Abdera was reduced under the power of Athens by Thrasybulus, then one of the Athenian generals in that quarter. A valuable prize, the city was repeatedly sacked: by the Triballi in 376, Philip II of Macedon in 350; later by Lysimachos of Thrace, the Seleucids, the Ptolemies, and again by the Macedonians. In 170 the Roman armies and those of Eumenes II of Pergamon besieged and sacked it. The town seems to have declined in importance after the middle of the 4th century. Cicero ridicules the city as a byword for stupidity in his letters to Atticus, writing of a debate in the Senate, \"Here was Abdera, but I wasn't silent\" (\"Hic, Abdera non tacente me\").

The reference to Venus is metaphorical, since the figurines predate the mythological figure of Venus by many thousands of years. Some scholars reject this terminology, instead referring to the statuette as the \"Woman of\" or \"Woman from Willendorf\". Christopher Witcombe criticizes the term: \"the ironic identification of these figurines as 'Venus' pleasantly satisfied certain assumptions at the time about the primitive, about women, and about taste\". Very little is known about the \"Venus\" origin, method of creation, or cultural significance; however, it is one of numerous \"Venus figurines\" surviving from Paleolithic Europe. The purpose of the carving is the subject of much speculation. Like other similar sculptures, it probably never had feet, and would not have stood on its own, although it might have been pegged into soft ground. Parts of the body associated with fertility and childbearing have been emphasized, leading researchers to believe that the \"Venus of Willendorf\" may have been used as a fertility fetish. The figure has no visible face, her head being covered with circular horizontal bands of what might be rows of plaited hair, or perhaps a type of headdress. Catherine McCoid and LeRoy McDermott hypothesize that the figurines may have been created as self-portraits by women. This theory stems from the correlation of the proportions of the statues to how the proportions of women's bodies would seem if they were looking down at themselves, which would have been the only way to view their bodies during this period. They speculate that the complete lack of facial features could be accounted for by the fact that sculptors did not own mirrors. This reasoning has been criticized by Michael S.

The text does not specify whether the king in the passage refers to Artaxerxes I (465–424 BCE) or to Artaxerxes II (404–359 BCE). Most scholars hold that Ezra lived during the rule of Artaxerxes I, though some have difficulties with this assumption: Nehemiah and Ezra \"seem to have no knowledge of each other; their missions do not overlap\", however, in Nehemiah 12, both are leading processions on the wall as part of the wall dedication ceremony. So, they clearly were contemporaries working together in Jerusalem at the time the wall and the city of Jerusalem was rebuilt in contrast to the previously stated viewpoint.;.\" These difficulties have led many scholars to assume that Ezra arrived in the seventh year of the rule of Artaxerxes II, i.e. some 50 years after Nehemiah. This assumption would imply that the biblical account is not chronological. The last group of scholars regard \"the seventh year\" as a scribal error and hold that the two men were contemporaries. However, Ezra appears for the first time in Nehemiah 8, having probably been at the court for twelve years. The rebuilding of the Jewish community in Jerusalem had begun under Cyrus the Great, who had permitted Jews held captive in Babylon to return to Jerusalem and rebuild Solomon's Temple. Consequently, a number of Jews returned to Jerusalem in 538 BC, and the foundation of this \"Second Temple\" was laid in 536 BC, in the second year of their return (Ezra 3:8). After a period of strife, the temple was finally completed in the sixth year of Darius, 516 BC (Ezra 6:15). In Artaxerxes' twentieth year, Nehemiah, the king's cup-bearer, apparently was also a friend of the king as in that year Artaxerxes inquired after Nehemiah's sadness. Nehemiah related to him the plight of the Jewish people and that the city of Jerusalem was undefended.

In his time, the abbey library increased from around fifty items to more than two thousand. He often served as featured speaker and chapter secretary at the Bursfelde Congregation's annual chapter from 1492 to 1503, the annual meeting of reform-minded abbots. Trithemius also supervised the visits of the Congregation's abbeys. Trithemius wrote extensively as a historian, starting with a chronicle of Sponheim and culminating in a two-volume work on the history of Hirsau Abbey. His work was distinguished by mastery of the Latin language and eloquent phrasing, yet it was soon discovered that he inserted several fictional passages into his works. His work as a historian has been tainted ever since, the invented passages proved by several scholars. However, his efforts did not meet with praise, and his reputation as a magician did not further his acceptance. Increasing differences with the convent led to his resignation in 1506, when he decided to take up the offer of the Bishop of Würzburg, Lorenz von Bibra (bishop from 1495 to 1519), to become the abbot of St. James's Abbey, the \"Schottenkloster\" in Würzburg.

Maneuvers were flown for artistic reasons or to draw gasps from onlookers. In due course some of these maneuvers were found to allow aircraft to gain tactical advantage during aerial combat or dogfights between fighter aircraft. Aerobatic aircraft fall into two categories—specialist aerobatic, and aerobatic capable. Specialist designs such as the Pitts Special, the Extra 200 and 300, and the Sukhoi Su-26M and Sukhoi Su-29 aim for ultimate aerobatic performance. This comes at the expense of general purpose use such as touring, or ease of non aerobatic handling such as landing. At a more basic level, \"aerobatic capable\" aircraft, such as the Cessna 152 Aerobat or the R2160 Acrobin, can be dual purpose—equipped to carrying passengers and luggage, as well as being capable of basic aerobatic figures. \"Flight formation aerobatics\" are flown by teams of up to sixteen aircraft, although most teams fly between four and ten aircraft. Some are state funded to reflect pride in the armed forces while others are commercially sponsored. Coloured smoke trails may be emitted to emphasise the patterns flown and/or the colours of a national flag. Usually each team will use aircraft similar to one another finished in a special and dramatic colour scheme, thus emphasising their entertainment function. Teams often fly V-formations (otherwise known as echelon formation)— they will not fly directly behind another aircraft because of danger from wake vortices or engine exhaust. Aircraft will always fly slightly below the aircraft in front, if they have to follow in line (the \"trail formation\"). Aerobatic maneuvers flown in a jet-powered aircraft are limited in scope as they cannot take advantage of the gyroscopic forces that a propeller driven aircraft can exploit. Jet-powered aircraft also tend to fly much faster, which increases the size of the figures and the length of time the pilot has to withstand increased g-forces. Jet aerobatic teams often fly in formations, which further restricts the maneuvers that can be safely flown. Aerobatics done at low levels and for an audience is called \"stunt flying\". To enhance the show effect of aerobatic maneuvers, smoke is sometimes generated; the smoke allows viewers to see the path travelled by the aircraft. Due to safety concerns, the smoke is not a result of combustion but is produced by the vaporization of fog oil into a fine aerosol, achieved either by injecting the oil into the hot engine exhaust or by the use of a dedicated device that can be fitted in any position on the aircraft.

All aerobatic maneuvers demand training and practice to avoid accidents. Accidents due to aerobatic manoeuvers are very rare in competition aerobatics, most of them happen when performing formation flying or stunt flying at very low levels at airshows or air racing. Low-level aerobatics are extremely demanding and airshow pilots must demonstrate their ability before being allowed to gradually reduce the height at which they may fly their show. In the EU, flying aerobatics requires a special training and license.

In 1914 he narrowly passed his matura exams and enrolled to study law at the University of Vienna, however, in April 1915 he joined the dragoon regiment No. 3 of the Austro-Hungarian Army and served in the mounted infantry at the Eastern Front in Galicia and Bukovina. On 12 July 1916 (during Brusilov Offensive) he was captured as a prisoner of war by the Imperial Russian Army in the area of Tlumach. A long way from home, in a Russian Far East camp for officer POWs in Krasnaya Rechka near Khabarovsk, he decided to become an author and began writing. Upon the Treaty of Brest-Litovsk he was released by the Bolshevik government, but had to make his way back to Austria through the Russian Civil War. Stranded in Samara, Doderer and his comrades again turned to the East, and found refuge in a Red Cross camp near Krasnoyarsk, cared for by Elsa Brändström. Many men had died from typhoid fever during their flight. Doderer stayed in Siberia until his eventual return to Austria in 1920; he finally reached Vienna on 14 August.

In 1936 he moved to Dachau, Germany, where he met Emma Maria Thoma, who would become his second wife in 1952. In Germany, he renewed his NSDAP membership (the Austrian Nazi Party had been banned since 1933). He returned to Vienna in 1938, sharing a flat with the celebrated painter Albert Paris Gütersloh. In that year the novel \"Ein Mord, den jeder begeht\" (\"A murder everyone commits\") was published. He converted to Catholicism in 1940 as a result of his reading of Thomas Aquinas and his alienation from the Nazis, which had been growing for some years. Also in 1940, Doderer was called up to the Wehrmacht and was later posted to German-occupied France, where he began work on his most celebrated novel \"Die Strudlhofstiege\" (the name refers to the so-called Strudlhofstiege, an outdoor staircase in Vienna).

Lambert also devised theorems regarding conic sections that made the calculation of the orbits of comets simpler. Lambert devised a formula for the relationship between the angles and the area of hyperbolic triangles. These are triangles drawn on a concave surface, as on a saddle, instead of the usual flat Euclidean surface. Lambert showed that the angles added up to less than π (radians), or 180°. The amount of shortfall, called the defect, increases with the area. The larger the triangle's area, the smaller the sum of the angles and hence the larger the defect C△ = π — (α + β + γ). That is, the area of a hyperbolic triangle (multiplied by a constant C) is equal to π (in radians), or 180°, minus the sum of the angles α, β, and γ. Here C denotes, in the present sense, the negative of the curvature of the surface (taking the negative is necessary as the curvature of a saddle surface is defined to be negative in the first place). As the triangle gets larger or smaller, the angles change in a way that forbids the existence of similar hyperbolic triangles, as only triangles that have the same angles will have the same area.

Later, another company called \"Skurfer\" was founded by Tony Finn in 1985, named as such due to the board being a cross of a surfboard and a water ski. The first board made in the early 1990s was the Hyperlite board by the O’Brien company, a water ski manufacturer who marketed the board as a “compression-molded neutral-buoyancy wakeboard.” This was followed by a variety of boards that are curvier and more compact, creating a smoother ride. The wakeboard rope has advanced over the years with improvements in the material makeup. When wakeboarding first started, wakeboarders used ski rope, which was made with stretchy cloth or plastic ropes. The latter soon grew in popularity, and a braided rope made out of polypropylene was eventually introduced. A few years later, a rope that was less stretchy was invented that gave the rider a more consistent pull on the rope, though they were heavier and larger in diameter. Modern ropes are coated with Spectra and Dyneema, which decrease the stretch and drag of the rope.", "section_level": 1}, {"title": "Equipment.", "content": "When wakeboarding, a wide variety of safety equipment is used. These include life vests or other buoyancy aids which prevent water-related injuries and deaths, as they keep the wearer buoyant until they are picked up. These vests especially help in situations where the rider is knocked unconscious or cannot tread water. Furthermore, wakeboarders use water-resistant helmets that are able to ventilate water so that the helmets do not fill up with water. Even the length of a wakeboarder's rope is important in providing safety; if the rope is too long, a wakeboarder will land on the flat part of the wake instead of the downside, and their knees will buckle. At the same time, the length of a wakeboarding rope will vary based on the rider's preferences. A longer rope may allow for more preparation and momentum before performing tricks, whereas a shorter rope may require less speed and height to travel between wakes.", "section_level": 1}, {"title": "Tricks.", "content": "When wakeboarding, a variety of tricks may be attempted. Most of these stem from the wakeboarder adjusting their posture, edge, and distribution of weight so as to fly into the air upon hitting the wake. Various tricks include the toeside edge, the heelside edge, the ride switch, and the 180° spin. More advanced tricks call for what is known as inversion or “inverts”. An invert is considered any action where the board is above the head of the rider. This does not necessarily mean the rider is fully upside down, as evidenced by the Raley, a trick where the rider extends their body parallel to the water bending at the knees to achieve inversion. The heel side backflip, otherwise known as a tantrum, is often regarded as the first and easiest invert to learn as an intermediate level rider. This is because the shape of the wake or the “kicker” (a type of floating ramp, used primarily at cable parks, that mimics the shape of a wake) naturally initiates the sequence of motions which are necessary to complete the trick.", "section_level": 1}], "src_summary": "Wakeboarding is a water sport in which the rider, standing on a wakeboard (a short board with foot bindings), is towed behind a motorboat across its wake and especially up off the crest in order to perform aerial maneuvers.

The rider is usually towed by a rope behind a boat, but can also be towed by cable systems and winches, and be pulled by other motorized vehicles like personal watercraft, cars, trucks, and all-terrain vehicles.

After a time spent in the marshes nearby, she was rescued by a priest and taken to a \"certain impregnable fortress,\" likely the fortified town of Canossa Castle near Reggio.

Part of Christian's appeal to the common people may be explained by the fact that he allowed Danish and Norwegian commoners into state service, but his attempts to curtail the influence of the nobility also meant continuing his father's drive toward absolutism. To accommodate non-aristocrats into state service, he created the new noble ranks of count and baron. One of the commoners elevated in this way by the king was Peder Schumacher, named Count of Griffenfeld by Christian V in 1670 and high councillor of Denmark in 1674. Griffenfeld, a skilled statesman, better understood the precarious situation Denmark-Norway placed itself by attacking Sweden at a time when the country was allied with France, the major European power of the era. After some hesitation, Christian V initiated the Scanian War (1675-1679) against Sweden in an attempt to reconquer Scania which Denmark the lost under the Treaty of Roskilde in 1658. As Griffenfeld predicted, Sweden's stronger ally France was the party that dictated the peace with Denmark's ally the Netherlands, and in spite of Danish victory at sea in the battles against Sweden in 1675–1679 during the Scanian War, Danish hopes for border changes on the Scandinavian Peninsula between the two countries were dashed. The results of the war efforts proved politically and financially unremunerative for Denmark-Norway. The damage to the Danish-Norwegian economy was extensive. At this point, Christian V no longer had his most experienced foreign relations counsel around to repair the political damage — in 1676 he had been persuaded to sacrifice Griffenfeld as a traitor, and to the clamour of his adversaries, Griffenfeld was imprisoned for the remainder of his life.

In spite of the family ties, war between the brothers-in-law was close again in 1689, when Charles XI nearly provoked confrontation with Denmark-Norway by his support of the exiled Christian Albert, Duke of Holstein-Gottorp in his claims to Holstein-Gottorp in Schleswig-Holstein. Like Charles XI of Sweden, who had never been outside Sweden, Christian V spoke only German and Danish and was therefore often considered poorly educated due to his inability to communicate with visiting foreign diplomats. Christian V was also often considered dependent on his councillors by contemporary sources. The Danish monarch did nothing to dispel this notion. In his memoirs, he listed \"hunting, love-making, war and maritime affairs\" as his main interests in life. Christian V introduced the Danish Code (\"Danske Lov\") in 1683, the first law code for all of Denmark. He also introduced the similar \"Norske Lov\" (Norwegian Code) of 1687 to replace Christian IVs Norwegian Code from 1604 in Norway. He also introduced the land register of 1688, which attempted to work out the land value of the united monarchy in order to create a more just taxation. During the reign of Christian V, Denmark's trade in cattle that had declined due to catastrophic fires and wars has been restored, and livestock and crop exports have also surpassed Frederick III, with thousands of cattle entering and leaving Jutland through the Oxen Way. After entering and fattening in the Danish King's German enclave County of Oldenburg,the castle reached the big market in Wedel. From there, cattle are resold to all parts of North Germany via Stade, Hamburg and Lübeck. As the population continues to soar at the end of the seventeenth century, demand for beef, grains and fish is increasing, both throughout North Germany and on the Baltic coast alone. In terms of the number of livestock shipped to the South, in 1680 each market had reached 40,000 cattle. Traditional export commodities, including fish and grains, have increased their exports since the beginning of the seventeenth century. The agricultural products exported by Denmark, especially cattle, have made a lot of money from Germany and the Netherlands for the Danish royal family, the aristocrats and the town residents. During his reign, science witnessed a golden age due to the work of the astronomer Ole Rømer in spite of the king's personal lack of scientific knowledge and interest.

Working primarily in the OEM field, ATI produced integrated graphics cards for PC manufacturers such as IBM and Commodore. By 1987, ATI had grown into an independent graphics-card retailer, introducing EGA Wonder and VGA Wonder card product lines that year. In the early nineties, they released products able to process graphics without the CPU: in May 1991, the Mach8, in 1992 the Mach32, which offered improved memory bandwidth and GUI acceleration. ATI Technologies Inc. went public in 1993, with shares listed on NASDAQ and on the Toronto Stock Exchange. In 1994, the Mach64 accelerator debuted, powering the Graphics Xpression and Graphics Pro Turbo, offering hardware support for YUV-to-RGB color space conversion in addition to hardware zoom; early techniques of hardware-based video acceleration. ATI introduced its first combination of 2D and 3D accelerator under the name 3D Rage. This chip was based on the Mach 64, but it featured elemental 3D acceleration. The ATI Rage line powered almost the entire range of ATI graphics products. In particular, the Rage Pro was one of the first viable 2D-plus-3D alternatives to 3Dfx's 3D-only Voodoo chipset. 3D acceleration in the Rage line advanced from the basic functionality within the initial 3D Rage to a more advanced DirectX 6.0 accelerator in 1999 Rage 128. The All-in-Wonder product line, introduced in 1996, was the first combination of integrated graphics chip with TV tuner card and the first chip that enabled display of computer graphics on a TV set. The cards featured 3D acceleration powered by ATI's 3D Rage II, 64-bit 2D performance, TV-quality video acceleration, analog video capture, TV tuner functionality, flicker-free TV-out and stereo TV audio reception. ATI entered the mobile computing sector by introducing 3D-graphics acceleration to laptops in 1996. The Mobility product line had to meet requirements different from those of desktop PCs, such as minimized power usage, reduced heat output, TMDS output capabilities for laptop screens, and maximized integration. In 1997, ATI acquired Tseng Labs's graphics assets, which included 40 engineers. The Radeon line of graphics products was unveiled in 2000. The initial Radeon graphics processing unit offered an all-new design with DirectX 7.0 3D acceleration, video acceleration, and 2D acceleration. Technology developed for a specific Radeon generation could be built in varying levels of features and performance in order to provide products suited for the entire market range, from high-end to budget to mobile versions. In 2000, ATI acquired ArtX, which engineered the Flipper graphics chip used in the Nintendo GameCube game console. They also created a modified version of the chip (codenamed Hollywood) for the successor of the GameCube, the Wii. Microsoft contracted ATI to design the graphics core (codenamed Xenos) for the Xbox 360.

His ancestors had been in Fusignano and land-owners there since 1506, when a Corelli moved to the area from Rome. Although apparently prosperous, they were almost certainly not of the nobility, as several fanciful accounts of the composer's genealogy subsequently claimed. Corelli's father, from whom he took the name Arcangelo, died five weeks before the composer's birth. Consequently, he was raised by his mother, Santa (\"née\" Ruffini, or Raffini), alongside four elder siblings. The wealth of anecdotes and legends attached to Corelli contrast sharply with the paucity of reliable contemporary evidence documenting events in his life. This gap is especially pronounced for his formative years, including his musical education, even though traditional accounts of a highly idealized childhood have long been debunked. According to the poet Giovanni Mario Crescimbeni, who presumably knew the composer well, Corelli initially studied music under a priest in the nearby town of Faenza, and then in Lugo, before moving in 1666 to Bologna. A major centre of musical culture of the time, Bologna had a flourishing school of violinists associated with Ercole Gaibara and his pupils, Giovanni Benvenuti and Leonardo Brugnoli. Reports by later sources link Corelli's musical studies with several master violinists, including Benvenuti, Brugnoli, Bartolomeo Laurenti and Giovanni Battista Bassani. Although historically plausible, these accounts remain largely unconfirmed, as does the claim that the papal contralto Matteo Simonelli first taught him composition. A remark Corelli later made to a patron suggests that his musical education focused mainly on the violin. Chronicles of the Accademia Filarmonica of Bologna indicate that Corelli was accepted as a member by 1670, at the exceptionally young age of seventeen. The credibility of this attribution has been disputed. Although the nickname \"Il Bolognese\" appears on the title-pages of Corelli's first three published sets of works (Opus 1 to 3), the duration of his stay in Bologna remains unclear. Anecdotes of trips outside Italy to France, Germany and Spain lack any contemporary evidence. For example, the anecdote that Corelli's continental fame stemmed from a trip to Paris at the age of nineteen, where he was chased away by an envious Jean-Baptiste Lully, seems to have originated with Jean-Jacques Rousseau. It was also claimed that Corelli spent time in Germany in the service of Maximilian II Emanuel, Elector of Bavaria (supposedly in 1681), as well as in the house of his friend and fellow violinist-composer Cristiano Farinelli (between 1680 and 1685). Although it is unclear quite when Corelli arrived in Rome, he was certainly active there by 1675, when \"Arcangelo Bolognese\" (as he was referred to) was engaged to play as one of the supporting violinists in lenten oratorios at the church of San Giovanni dei Fiorentini, as well as in the French national celebrations held each year on 25 August at San Luigi dei Francesi and during the ordination of a member of the powerful Chigi family at Santi Domenico e Sisto. In August 1676, he was already playing second violin to the renowned Carlo Mannelli at San Luigi dei Francesi. Although Rome did not have any permanent orchestra providing stable employment for instrumentalists, Corelli rapidly made a name for himself, playing in a variety of ensembles sponsored by wealthy patrons, such as Cardinal Benedetto Pamphili, for whom he played in Lenten oratorios at San Marcello from 1676 to 1679. In 1687 Corelli led the festival performances of music for Queen Christina of Sweden. He was also a favorite of Cardinal Pietro Ottoboni, grandnephew of another Cardinal Pietro Ottoboni, who in 1689 became Pope Alexander VIII. From 1689 to 1690 he was in Modena. The Duke of Modena was generous to him. In 1706 Corelli was elected a member of the Pontificia Accademia degli Arcadi (the Arcadian Academy of Rome). He received the Arcadian name of Arcomelo Erimanteo. In 1708 he returned to Rome, living in the palace of Cardinal Ottoboni. His visit to Naples, at the invitation of the king, took place in the same year. The style of execution introduced by Corelli and preserved by his pupils, such as Francesco Geminiani, Pietro Locatelli, Pietro Castrucci, Francesco Antonio Bonporti, Giovanni Stefano Carbonelli, Francesco Gasparini, and others, was of vital importance for the development of violin playing. It has been said that the paths of all of the famous violinist-composers of 18th-century Italy led to Arcangelo Corelli, who was their \"iconic point of reference\". However, Corelli used only a limited portion of his instrument's capabilities. This may be seen from his writings. The parts for violin very rarely proceed above D on the highest string, sometimes reaching the E in fourth position on the highest string. The story has been told and retold that Corelli refused to play a passage that extended to A in altissimo in the overture to Handel's oratorio \"The Triumph of Time and Truth\" (premiered in Rome, 1708), and felt seriously offended when the composer (32 years his junior) played the note. Nevertheless, his compositions for the instrument mark an epoch in the history of chamber music. His influence was not confined to his own country. Johann Sebastian Bach studied the works of Corelli and based an organ fugue (BWV 579) on Corelli's Opus 3 of 1689. Handel's Opus 6 \"Concerti Grossi\" take Corelli's own older Opus 6 \"Concerti\" as models, rather than the later three-movement Venetian concerto of Antonio Vivaldi favoured by Bach. Musical society in Rome also owed much to Corelli. He was received in the highest circles of the aristocracy, and for a long time presided at the celebrated Monday concerts in the palace of Cardinal Ottoboni. Corelli died in Rome in possession of a fortune of 120,000 marks and a valuable collection of works of art and fine violins, the only luxury in which he had indulged. He left both to his benefactor and friend, who generously made over the money to Corelli's relatives. Corelli is buried in the Pantheon at Rome. His concerti grossi have often been popular in Western culture. For example, a portion of the \"Christmas Concerto\", Op. 6 No. 8, is in the soundtrack of the film \"\", and Corelli's Op. 6 No. 2 also provided the theme for Sir Michael Tippett's \"Fantasia Concertante on a Theme of Corelli\".", "section_level": 1}, {"title": "Works.", "content": "Corelli composed 48 trio sonatas, 12 violin and continuo sonatas, and 12 concerti grossi.

His father was Mathias Haydn, a wheelwright who also served as \"Marktrichter\", an office akin to village mayor. Haydn's mother Maria, Koller, had previously worked as a cook in the palace of Count Harrach, the presiding aristocrat of Rohrau. Mathias was an enthusiastic folk musician, who during the journeyman period of his career had taught himself to play the harp, and he also made sure that his children learned to sing. Michael went to Vienna at the age of eight, his early professional career path being paved by his older brother Joseph, whose skillful singing had landed him a position as a boy soprano in the St. Stephen's Cathedral, Vienna choir under the direction of Georg Reutter, as were Johann Georg Albrechtsberger and Franz Joseph Aumann, both composers with whom Haydn later traded manuscripts. By Michael's 12th birthday he was earning extra money as a substitute organist at the cathedral and had, reportedly, performed preludes and fantasies of his own composition. The early 19th-century author Albert Christoph Dies, based on Joseph's late-life reminiscences, wrote: Reutter was so captivated by [Joseph]'s talents that he declared to his father that even if he had twelve sons he would take care of them all. The father saw himself freed of a great burden by this offer, consented to it, and some five years after dedicated Joseph's brothers Michael, and still later Johann to the musical muse. Both were taken on as choirboys, and, to Joseph's unending joy, both brothers were turned over to him to be trained. The same source indicates that Michael was a brighter student than Joseph, and that (particularly when Joseph had grown enough to have trouble keeping his soprano voice) it was Michael's singing that was the more admired. About 1753, he left the choir school because of the breaking of his voice. In 1760 Michael was appointed Kapellmeister at Großwardein (today Oradea) and later, in 1762, was appointed concertmaster at Salzburg, where he remained for 44 years, during which he wrote over 360 compositions comprising both church and instrumental music. From their mutual sojourn in Salzburg, Haydn was acquainted with Mozart, who held his work in high esteem. On 17 August 1768 he married singer Maria Magdalena Lipp (1745–1827); their only child, a daughter (Aloisia Josepha, born 31 January 1770) died just short of her first birthday, on 27 January 1771. Although Lipp was disliked by the women in Mozart's family for some reason, she still created the role of \"\" ([Divine] Mercy) in Mozart's first musical play, \"Die Schuldigkeit des ersten Gebots\" (\"The Obligation of the First Commandment\"), 1767, and later the role of Tamiri in his short pastoral opera \"Il re pastore\" of 1775. Leopold Mozart criticized Haydn's heavy drinking. In Salzburg Haydn taught young Carl Maria von Weber and Anton Diabelli. Michael remained close to Joseph all of his life. Joseph regarded his brother's music highly, to the point of feeling Michael's religious works were superior to his own (possibly for their devotional intimacy, as opposed to Joseph's monumental and majestic, more secularized, symphonic style). In 1802, when Michael was \"offered lucrative and honourable positions\" by \"both Esterházy and the Grand Duke of Tuscany,\" he wrote to Joseph in Vienna asking for advice on whether or not to accept any of them, but in the end chose to stay in Salzburg. Michael and Maria Magdalena Haydn named their daughter Aloisia Josepha not in honor of Michael's brother, but after Josepha Daubrawa von Daubrawaick, who substituted as godmother at the baptism for Countess de Firmian. He died in Salzburg at the age of 68.", "section_level": 1}, {"title": "Works.", "content": "Musicologist Karl Geiringer has claimed that Michael Haydn has not received the recognition he deserves from posterity, taking the view that his church music, his choruses for male voices, and many of his instrumental works are on respectable level and ought to be revived. Michael Haydn never compiled a thematic catalog of his works, nor did he ever supervise the making of one. The earliest catalog was compiled in 1808 by Nikolaus Lang for his 'Biographische Skizze' (Biographical Sketch). In 1907 Lothar Perger compiled a catalogue of his orchestral works, the Perger-Verzeichnis, for \"Denkmäler der Tonkunst in Österreich\", which is somewhat more reliable than Lang's catalog and attaches P. (for Perger) numbers to many of Haydn's instrumental works. And in 1915 Anton Maria Klafsky undertook a similar work regarding Michael's sacred vocal music. In 1982, Charles H. Sherman, who has edited scores of many of his symphonies for Doblinger, published a chronological catalog of them which some recording companies have adopted. Later, in 1991, Sherman joined forces with T. Donley Thomas to publish a chronological catalog of Michael's complete works using a single continuous range of numbers after Köchel's pioneering catalog of all of Mozart's works and Otto Erich Deutsch's similar comprehensive compendium for all of Schubert's works. Further important amendments to the Sherman/Thomas catalogue have been made by Dwight Blazin. The task of cataloging Michael's music is facilitated by the fact that he almost always entered the date of completion on his manuscripts. Guesswork was necessary only where autograph manuscripts did not survive. Haydn's sacred choral works are generally regarded as his most important; his musical taste and skill showed themselves best in his church compositions and were already in his lifetime old-fashioned. Some of these works include the \"Requiem pro defuncto Archiepiscopo Sigismundo\" (Requiem for the death of Archbishop Siegmund) in C minor, which greatly influenced the \"Requiem\" by Mozart; \"Missa Hispanica\" (which he exchanged for a diploma at Stockholm); his magnificent last St. Francis Mass in D minor; the motet \"Lauda Sion\" which he wished to have sung at his funeral; and a set of graduals, forty-two of which are reprinted in Anton Diabelli's \"Ecclesiasticon\". He wrote several settings of the mass ordinary in German by Franz Seraph von Kohlbrenner, named \"Deutsches Hochamt\". Haydn was also a prolific composer of secular music, including forty symphonies and wind partitas, and multiple concertos and chamber music including a string quintet in C major was once thought to have been by his brother Joseph. There was another case of posthumous mistaken identity involving Michael Haydn: for many years, the G major symphony now known to be Michael Haydn's Symphony No. 25 was thought to be Mozart's Symphony No. 37 and assigned as K. 444. The confusion arose because an autograph was discovered with the opening movement of the symphony in Mozart's hand and the rest in another's hand. It is now known that Mozart composed the slow introduction to the first movement but the rest of the work is by Michael. As a result, this work, which had been quite widely played when thought to be a Mozart symphony, has been performed considerably less often since this discovery in 1907. Indeed, several of Michael Haydn's works influenced Mozart. To give just three examples: the \"Te Deum\" \"which Wolfgang was later to follow very closely in K. 141\"; the finale of the Symphony No. 23 which influenced the finale of the G major Quartet, K. 387; and the (fugal) transition and (nonfugal) closing theme of the G major second subject expositions of the finales of both Michael's Symphony No. 28 (1784) and Mozart's monumental last Symphony No. 41 (\"Jupiter\") (1788), both in C major.", "section_level": 1}], "src_summary": "Johann Michael Haydn (; 14 September 173710 August 1806) was an Austrian composer of the Classical period, the younger brother of Franz Joseph Haydn.", "tgt_summary": null, "id": 4971839} {"src_title": "Alessandro Scarlatti", "tgt_title": null, "src_document": [{"title": "Life.", "content": "Scarlatti was born in Palermo (or in Trapani), then part of the Kingdom of Sicily. He is generally said to have been a pupil of Giacomo Carissimi in Rome, and some theorize that he had some connection with northern Italy because his early works seem to show the influence of Stradella and Legrenzi. The production at Rome of his opera \"Gli equivoci nel sembiante\" (1679) gained him the support of Queen Christina of Sweden (who at the time was living in Rome), and he became her \"maestro di cappella\". In February 1684 he became \"maestro di cappella\" to the viceroy of Naples, perhaps through the influence of his sister, an opera singer, who might have been the mistress of an influential Neapolitan noble. Here he produced a long series of operas, remarkable chiefly for their fluency and expressiveness, as well as other music for state occasions. In 1702 Scarlatti left Naples and did not return until the Spanish domination had been superseded by that of the Austrians. In the interval he enjoyed the patronage of Ferdinando de' Medici, for whose private theatre near Florence he composed operas, and of Cardinal Ottoboni, who made him his \"maestro di cappella\", and procured him a similar post at the Basilica di Santa Maria Maggiore in Rome in 1703. After visiting Venice and Urbino in 1707, Scarlatti took up his duties in Naples again in 1708, and remained there until 1717. By this time Naples seems to have become tired of his music; the Romans, however, appreciated it better, and it was at the Teatro Capranica in Rome that he produced some of his finest operas (\"Telemaco\", 1718; \"Marco Attilio Regolò\", 1719; \"La Griselda\", 1721), as well as some noble specimens of church music, including a \"Messa di Santa Cecilia\" for chorus and orchestra, composed in honor of Saint Cecilia for Cardinal Francesco Acquaviva in 1721. His last work on a large scale appears to have been the unfinished \"Erminia\" serenata for the marriage of the prince of Stigliano in 1723. He died in Naples in 1725 and is entombed there at the church of Santa Maria di Montesanto.", "section_level": 1}, {"title": "Scarlatti's music.", "content": "Scarlatti's music forms an important link between the early Baroque Italian vocal styles of the 17th century, with their centers in Florence, Venice and Rome, and the classical school of the 18th century. Scarlatti's style, however, is more than a transitional element in Western music; like most of his Naples colleagues he shows an almost modern understanding of the psychology of modulation and also frequently makes use of the ever-changing phrase lengths so typical of the Napoli school. His early operas—\"Gli equivoci nel sembiante\" 1679; \"L'honestà negli amori\" 1680, containing the famous aria \"Già il sole dal Gange\"; \"Il Pompeo\" 1683, containing the well-known airs \"O cessate di piagarmi\" and \"Toglietemi la vita ancor,\" and others down to about 1685—retain the older cadences in their recitatives, and a considerable variety of neatly constructed forms in their charming little arias, accompanied sometimes by the string quartet, treated with careful elaboration, sometimes with the continuo alone. By 1686, he had definitely established the \"Italian overture\" form (second edition of \"Dal male il bene\"), and had abandoned the ground bass and the binary form air in two stanzas in favour of the ternary form or da capo type of air. His best operas of this period are \"La Rosaura\" (1690, printed by the Gesellschaft für Musikforschung), and \"Pirro e Demetrio\" (1694), in which occur the arias \"Le Violette\", and \"Ben ti sta, traditor\". From about 1697 onwards (\"La caduta del Decemviri\"), influenced partly perhaps by the style of Giovanni Bononcini and probably more by the taste of the viceregal court, his opera arias become more conventional and commonplace in rhythm, while his scoring is hasty and crude, yet not without brilliance (\"L'Eraclea\", 1700), the oboes and trumpets being frequently used, and the violins often playing in unison. The operas composed for Ferdinando de' Medici are lost; they might have given a more favourable idea of his style as his correspondence with the prince shows that they were composed with a very sincere sense of inspiration. \"Mitridate Eupatore\", accounted his masterpiece, composed for Venice in 1707, contains music far in advance of anything that Scarlatti had written for Naples, both in technique and in intellectual power. The later Neapolitan operas (\"L'amor volubile e tiranno\" 1709; \"La principessa fedele\" 1710; \"Tigrane\", 1714, &c.) are showy and effective rather than profoundly emotional; the instrumentation marks a great advance on previous work, since the main duty of accompanying the voice is thrown upon the string quartet, the harpsichord being reserved exclusively for the noisy instrumental \"ritornelli\". In his opera \"Teodora\" (1697) he originated the use of the orchestral \"ritornello\". His last group of operas, composed for Rome, exhibit a deeper poetic feeling, a broad and dignified style of melody, a strong dramatic sense, especially in accompanied recitatives, a device which he himself had been the first to use as early as 1686 (\"Olimpia vendicata\") and a much more modern style of orchestration, the horns appearing for the first time, and being treated with striking effect. Besides the operas, oratorios (\"Agar et Ismaele esiliati\", 1684; \"La Maddalena\", 1685; \"La Giuditta\", 1693; \"Christmas Oratorio\", c. 1705; \"S. Filippo Neri\", 1714; and others) and serenatas, which all exhibit a similar style, Scarlatti composed upwards of five hundred chamber-cantatas for solo voice. These represent the most intellectual type of chamber-music of their period, and it is to be regretted that they have remained almost entirely in manuscript, since a careful study of them is indispensable to anyone who wishes to form an adequate idea of Scarlatti's development. His few remaining Masses (the story of his having composed two hundred is hardly credible) and church music in general are comparatively unimportant, except the great \"Saint Cecilia Mass\" (1721), which is one of the first attempts at the style which reached its height in the great Masses of Johann Sebastian Bach and Ludwig van Beethoven.

Frederick's general, Johann Rantzau, moved his army to Scania and defeated the peasants soundly in April and May 1525. Frederick played a central role in the spread of Lutheran teaching throughout Denmark. In his coronation charter, he was made the solemn protector (\"værner\") of Roman Catholicism in Denmark. In that role, he asserted his right to select bishops for the Roman Catholic dioceses in the country. Christian II had been intolerant of Protestant teaching, but Frederick took a more opportunist approach. For example, he ordered that Lutherans and Roman Catholics share the same churches and encouraged the first publication of the Bible in the Danish language. In 1526, when Lutheran Reformer Hans Tausen was threatened with arrest and trial for heresy, Frederick appointed him his personal chaplain to give him immunity. Starting in 1527, Frederick authorized the closure of Franciscan houses and monasteries in 28 Danish cities.

The Kingdom of Italy, like some of the other European powers, wanted to set up colonies and build up an overseas empire. Although France had supported Italian unification, Italy's colonial ambitions in Africa quickly brought it into a rivalry with France. That was reflected in anger at the French seizure of Tunisia in 1881, the so-called \"Schiaffo di Tunisi\" by Italian press, which many Italians had seen as a potential colony. By joining the Alliance, Italy hoped to guarantee itself support in case of foreign aggression. The main alliance compelled any signatory country to support the other parties if two other countries attacked. Germany had won a war against France in 1870 and was a natural ally for Italy. Thus, Italy found itself coming to terms with its historical enemy, Austria-Hungary, against which Italy had fought three wars in the 34 years before the signing of the first treaty. However, Italian public opinion remained unenthusiastic about their country's alignment with Austria-Hungary, a past enemy of Italian unification and whose Italian-populated districts in the Trentino and Istria were seen as occupied territories by Italian irredentists. In the years before World War I, many distinguished military analysts predicted that Italy would attack its supposed ally in the event of a large scale conflict. Italy's adherence to the Triple Alliance was doubted, and from 1903 plans for a possible war against Rome were again maintained by the Austro-Hungarian General Staff. Mutual suspicions led to reinforcement of the frontier and speculation in the press about a war between the two countries into the first decade of the 20th century. As late as 1911, Count Franz Conrad von Hötzendorf, the chief of the Austro-Hungarian General Staff, was advocating a preemptive strike against Austria's supposed Italian ally.

While in Detroit he began to get recognition appearing in local television commercials and appearing on cable comedy shows such as Gary Thison's \"Some Semblance of Sanity\". On October 2, 1978, Allen was arrested in the Kalamazoo/Battle Creek International Airport for possession of over of cocaine. He subsequently pleaded guilty to felony drug trafficking charges and provided the names of other dealers in exchange for a sentence of three to seven years rather than a possible life imprisonment. He was paroled on June 12, 1981, after serving two years and four months in Federal Correctional Institution, Sandstone in Sandstone, Minnesota. Following his release from prison, he returned to comedy. He moved to Los Angeles and became a regular performer at The Comedy Store. He began to do stand-up appearances on late-night talk shows and specials on record and film. Despite his admitted limited acting range (he once told a magazine his range as an actor is \"... strictly limited. I can only play a part if I can draw on personal experience, and that well can go dry pretty quickly\"), Allen rose to fame in acting with the ABC sitcom \"Home Improvement\" (1991–1999) produced for ABC by Wind Dancer Productions, a company he co-founded with producer Carmen Finestra. Allen played the main character Tim \"The Tool-Man\" Taylor. In November 1994, he simultaneously starred in the highest-grossing film (Disney's \"The Santa Clause\"), topped the \"New York Times\" bestseller list with his book \"Don't Stand Too Close to a Naked Man\", and appeared in the top rated television series (\"Home Improvement\") within the span of one week. \"Home Improvement\" ran until 1999, for which he was paid US$1.25 million per episode. In 1995, Allen provided the voice of Buzz Lightyear in the Disney/Pixar blockbuster \"Toy Story\". In 1997, he starred in the family comedy \"Jungle 2 Jungle\" from Disney. The next year he returned to voice Buzz Lightyear in \"Toy Story 2\" which was a financial and critical hit. That same year, Allen was arrested for DUI in Birmingham, Michigan. At the time, his blood alcohol content was 0.15, nearly double the legal limit in Michigan. He was sentenced to one-year probation and entered a rehabilitation clinic for alcohol abuse as part of his court obligation. In 1999, he starred in the sci-fi parody \"Galaxy Quest\" alongside Sigourney Weaver, Alan Rickman, and Sam Rockwell. In 2002, he reprised his role as Scott Calvin in \"The Santa Clause 2\". Two years later, he starred as Luther Krank in \"Christmas with the Kranks\". In 2006, \"Zoom\" was released, starring Allen as Jack Shepard. The same year, he also starred in \"The Shaggy Dog\" and \"The Santa Clause 3\". 2008 marked his first dramatic turn with a supporting role as an aging action movie star in David Mamet's \"Redbelt\". Allen began narrating the \"Pure Michigan\" television and radio commercials for the \"Travel Michigan\" agency. These commercials can be seen and heard throughout the Midwest and began airing nationally in 2009. In December 2009, he started a preview tour of \"Crazy on the Outside\", a film that debuted in January 2010. Allen accompanied the film, helping promote it with a series of stand-up acts beforehand. During the performances, he told audiences that he planned a 2010 comedy tour. Allen also directed the film, marking his film directorial debut. Allen hosted the 8th Annual TV Land Awards on April 25, 2010. That same year, he became the official voice of the Chevrolet Cruze, narrating commercials for the vehicle, and he became the voice of Campbell Soup's \"It's Amazing What Soup Can Do\" campaign.

In the context of modern theistic evolution, \"hominization\" refers to the theory that there was a point at which a population of hominids who had (or may have) evolved by a process of evolution acquired souls and thus (with their descendants) became fully human in theological terms. This group might be restricted to Adam and Eve, or indeed to Mitochondrial Eve, although versions of the theory allow for larger populations. The point at which this occurred should essentially be the same as in paleoanthropology and archeology, but theological discussion of the matter tends to concentrate on the theoretical. The term \"special transformism\" refers to theories of a divine intervention of some sort, achieving hominization. The process and means by which hominization occurs is a key problem in theistic evolutionary thought, at least for the Abrahamic religions, for which the belief that animals do not have souls but humans do is a core teaching. Scientific accounts of the origin of the universe, origin of life and subsequent evolution of pre-human life forms may not cause any difficulty (helped by the reluctance of science itself to say anything about what preceded the Big Bang) but the need to reconcile religious and scientific views of hominization and account for the addition of a soul to humans remains a problem.

Five prototypes were ordered from each company; the Junkers Ju 86 and Heinkel He 111. Junkers' design was a low-winged twin-engined monoplane, of all-metal stressed skin construction. Unlike most of Junkers' previous designs, it discarded the typical corrugated skinning in favour of smooth metal skinning which helped to reduce drag. The craft was fitted with a narrow track retractable-main gear conventional undercarriage with a fixed tailwheel, and twin fins and rudders. It was intended to be powered by Junkers Jumo 205 diesel engines, which although heavy, gave better fuel consumption than conventional petrol engines. The design featured the distinctive Junkers \"doppelflügel\" control surfaces on the wing, similar to those on the Junkers Ju 52. These were hinged below the wing's trailing edge, with the outboard section on each side functioning as an aileron, and the inner section functioning as a wing flap. The bomber aircraft had a crew of four; a pilot, navigator, radio operator/bombardier and gunner. Defensive armament consisted of three machine guns, situated at the nose; at a dorsal position; and within a retractable ventral position. Bombs were carried vertically in four fuselage cells behind the cockpit. The airliner version replaced the bomb cells with seating for ten passengers, with fuel tanks being moved from the fuselage to the wings. Jumo 205s were unavailable when the first prototype airframe was completed. Instead, the bomber-configured Ju 86ab1 was fitted with Siemens SAM 22 radial engines and flew for the first time on 4 November 1934. The second prototype, also a bomber, flew in January 1935. The third Ju 86, the first civil prototype, flew on 4 April 1935. Production of pre-series military and civil aircraft started in late 1935, with full production of the Ju 86A-1 bomber commencing in April 1936. Production quickly switched to the improved Ju 86D with a modified tail cone to improve stability. Early use of the Jumo-powered Ju 86 bomber in the Spanish Civil War showed that it was inferior to the He 111, with the diesel engines being unsuitable for rough treatment during combat; and production plans were cut back. One Ju 86 had already been converted to use radial engines as a testbed for possible export versions, and this showed improved reliability. Production switched to a version powered by the BMW 132 engine, the Ju 86E, with production continuing until 1938. Civil variants, introduced in 1936, were designated Ju 86Z in three different models differing in their engines. The Jumo-engined Ju 86Z-1 (corresponding to the former B-0 or C-1) was sold to Swissair (one), Airlines of Australia (one), and LAN-Chile (three). The BMW 132H-powered Ju 86Z-2 was sold to DLH (two) and the para-military Manchukuo Air Transport (five or more). The Pratt & Whitney R-1690 Hornet-engined Ju 86Z-7 was delivered to AB Aerotransport (ABA) of Sweden (one, for use as a mail carrier), Lloyd Aéreo Boliviano (three), and South African Airways - SAA - (17). The ABA aircraft was later transferred to the Swedish Air Force, with which it served, under the designation Tp 9, until 1958. South African Airways' original intention was to have its Ju 86s powered by 745 hp Rolls-Royce Kestrels. Six aircraft for SAA, flown with these engines, were refitted with Hornets before delivery, and the remainder were also Hornet-powered. The Ju 86K was an export model, also built under license in Sweden by Saab as the B 3 with (905 hp) Bristol Mercury XIX radial engines.

Four Ju 86D-1s arrived in Spain in early February 1937, but after a few sorties one of them was shot down on 23 February by Republican fighters with the loss of three crewmen killed and one captured. A replacement aircraft was sent from Germany, but in the summer of 1937 another was lost in an accident, and the three remaining aircraft were sold to the Nationalist air forces. Ju 86s were again used in the 1939 invasion of Poland, but retired soon after. In January 1940, the \"Luftwaffe\" tested the prototype Ju 86P with a longer wingspan, pressurized cabin, Junkers Jumo 207A-1 turbocharged two-stroke, opposed-piston diesel engines and a two-man crew. The Ju 86P could fly at heights of 12,000 m (39,000 ft) and higher on occasion, where it was felt to be safe from enemy fighters. The British Westland Welkin and Soviet Yakovlev Yak-9PD were developed specifically to counter this threat. At the outbreak of the Second World War, South Africa's Ju 86Zs were militarised and armed as bombers with defensive guns and external bomb racks. These aircraft were initially used for coastal patrols along with the sole Ju 86K-1, playing an important role in the interception of the German blockade runner SS \"Watussi\" in December 1939. In May 1940, they were used to re-equip No. 12 Squadron SAAF, which was deployed in the East African Campaign from June 1940. It flew its first bombing missions on 14 June 1940. As more modern aircraft became available, the South African Ju 86s were passed from squadron to squadron, seeing their last use with No. 22 Squadron SAAF, which used it along with the Avro Anson in the coastal reconnaissance role, finally retiring its Ju 86s in September 1942. Satisfied with the trials of the new Ju 86P prototype, the \"Luftwaffe\" ordered that some 40 older-model bombers be converted to Ju 86P-1 high-altitude bombers and Ju 86P-2 photo-reconnaissance aircraft. Those operated successfully for some years over Britain, the Soviet Union and North Africa. In August 1942, a modified Supermarine Spitfire V shot one down over Egypt at an altitude of some 14,500 m (49,000 ft); when two more were lost, Ju 86Ps were withdrawn from service in 1943.

To this date, the Christkindl \"remains the main gift bringer in many Catholic countries in Latin America.\" The Christkind is a sprite-like child, usually depicted with blond hair and angelic wings. Martin Luther intended it to be a reference to the incarnation of Jesus as an infant (see Christ Child). Sometimes the Christ Child is, instead of the infant Jesus, interpreted as a specific angel bringing the presents, as it appears in some processions together with an image of little Jesus Christ. Later, the Christkind was said to make rounds delivering gifts with St. Nicholas. Children never see the Christkind in person, and parents tell them that Christkind will not come and bring presents if they are curious and try to spot it. The family enters the living room, where the Christmas tree has been put up, for the opening of presents (the \"Bescherung\"), when the parents say that they think that the Christkind who has brought the presents has now left again. In some traditions, the departure is announced by the ringing of a small bell, which the parents pretend to have heard or which is secretly done by one of the adults in the family. Since the 1990s, the Christkind has faced increasing competition from the Weihnachtsmann, caused by the use of the American version of Santa Claus as an advertising figure. Many traditionalist Catholics in recent times have advocated for the tradition of the Christkind as a \"beautiful means of restoring the true meaning of Christmas\".

Because Julianus bought his position rather than acquiring it conventionally through succession or conquest, he was a deeply unpopular emperor. When Julianus appeared in public, he frequently was greeted with groans and shouts of \"robber and parricide.\" Once, a mob even obstructed his progress to the Capitol by pelting him with large stones. When news of the public anger in Rome spread across the Empire, three influential generals, Pescennius Niger in Syria, Septimius Severus in Pannonia, and Clodius Albinus in Britain, each able to muster three legions, rebelled. They refused to accept Julianus' authority as emperor and instead declared themselves emperor. Julianus declared Severus a public enemy because he was the nearest of the three to Rome, making him the most dangerous foe. Julianus sent senators to persuade Severus' legionaries to abandon him, a new general was nominated to replace him, and a centurion dispatched to take Severus' life. The Praetorian Guard had rarely fought in field battles, so Julianus marched them into the Campus Martius and drilled the guard in the construction of fortifications and field works. Despite this training, the Praetorian Guard was still undertrained compared to the field legionaries of Severus. Severus first secured the support of Albinus, declaring him Caesar, and then seized Ravenna and its fleet. Severus killed Tullius Crispinus, the Praetorian prefect, who was sent to negotiate with Severus and slow his march on Rome and won over to his cause the ambassadors sent to turn his troops. Cassius Dio maintains that the Praetorian Guard tried to fight back, but were crushed, while modern historians believe that the Praetorian Guard simply abandoned Julianus, deserting \"en masse\". Julianus attempted to negotiate with Severus, offering to share the empire with his rival, but Severus ignored these overtures and pressed forward. As he marched, more and more cities in Italy supported his claim to the throne. The remnants of the Praetorian Guard received pardons from Severus in exchange for surrendering the actual murderers of Pertinax. After seizing the ringleaders and killing them, the soldiers reported what they had done to Marcus Silius Messala, the consul, who summoned the senate to inform them of the proceedings.

He wrote \"My Beautiful Laundrette\" in 1985, a screenplay about a gay Pakistani-British boy growing up in 1980s London for a film directed by Stephen Frears. The screenplay, especially the racial discrimination experienced, contained elements from Hanif's own experiences as the only Pakistani student in his class at school. It won the New York Film Critics Best Screenplay Award and an Academy Award nomination for Best Screenplay. He also wrote the screenplay for \"Sammy and Rosie Get Laid\" (1987). His book \"The Buddha of Suburbia\" (1990) won the Whitbread Award for the best first novel and was made into a BBC television series with a soundtrack by David Bowie. 1991 saw the release of the feature film entitled \"London Kills Me\", written and directed by Kureishi. His novel \"Intimacy\" (1998) revolved around the story of a man leaving his wife and two young sons after feeling physically and emotionally rejected by his wife. This created some controversy as Kureishi had recently left his own partner (the editor and producer Tracey Scoffield) and two young sons; it was assumed to be at least semi-autobiographical. In 2000/2001 the novel was adapted into a film, \"Intimacy\" by Patrice Chéreau, which won two Bears at the Berlin Film Festival: a Golden Bear for Best Film and a Silver Bear for Best Actress (Kerry Fox). It was controversial for its explicit sex scenes. The book was translated into Persian by Niki Karimi in 2005. Kureishi's drama \"The Mother\" was adapted to a movie by Roger Michell, which won a joint First Prize in the Director’s Fortnight section at Cannes Film Festival. It showed a cross-generational relationship with changed roles: a seventy-year-old English lady and grandmother (played by Anne Reid) who seduces her daughter's boyfriend (played by Daniel Craig), a thirty-year-old craftsman. Explicit sex scenes were shown in realistic drawings only, thus avoiding censorship. His 2006 screenplay \"Venus\" saw Oscar, BAFTA, Screen Actors Guild, Broadcast Film Critics Association and Golden Globe nominations for Peter O'Toole in the best actor category.

Upon a 2012 visit sponsored by the British Council, he acknowledged that it was his first trip to Pakistan in 20 years. Kureishi's family have accused him of exploiting them with thinly disguised references in his work; Kureishi has denied the claims. His sister Yasmin has accused him of selling her family \"down the line\". She wrote, in a letter to \"The Guardian\", that if her family's history had to become public, she would not stand by and let it be \"fabricated for the entertainment of the public or for Hanif's profit\". She says that his description of her family's working-class roots are fictitious. Their grandfather was not \"cloth cap working class\", their mother never worked in a shoe factory, and their father, she says, was not a bitter old man. Yasmin takes up issues with her brother not merely for his thinly disguised autobiographical references in his first novel, \"The Buddha of Suburbia\", but also for the image of his own past that he portrays in newspaper interviews. She wrote: \"My father was angry when \"The Buddha of Suburbia\" came out as he felt that Hanif had robbed him of his dignity, and he didn't speak to Hanif for about a year.\" Kureishi and his father did not speak for many months during the controversy. There was further furore with the publication of \"Intimacy\", as the story was assumed to be autobiographical. In 2013 Kureishi was appointed as a professor in the creative writing department at Kingston University in London, where he was a Writer in Residence. However, at \"The Independent\" Bath Literature Festival, 2 March 2014, he stated that creative writing courses were a \"waste of time\" and commented that 99.9 per cent of his students were talentless.

Several more unpowered flights took place that month. The biggest problem had to do with the center of gravity which was restored with the addition of counterweights. Eventually, the production aircraft would have repositioned the engine or the landing gear installation to solve this problem. The landing gear was still non-retractable. The first flights gave the impression that it was suitable as it was for production. Test flights were later stopped because of fuel shortages for the Bf 110 towplanes. As the Me 263 was not a part of the \"Jägernotprogramm\" (Emergency Fighter Program), it was difficult to get the resources it needed. For the time being the plane was not expected to enter production but further development was allowed. The V2 and V3 were not yet ready. The V2 was to get the retractable landing gear and the V3 would have the armament built in. The next month both the V1 and the V2 had the two-chambered HWK 109-509C installed, correcting the center-of-gravity problems. They flew only as gliders. In April, the Americans occupied the plant and captured the three prototypes and the mock-up. The V2 was destroyed but another prototype ended up in the US.

In Ruotger, the title served as an honorific denoting Bruno's unusual position rather than a formal office. The title was not used systematically until the 14th century, when the title \"Archduke of Austria\" was invented in the forged \"Privilegium Maius\" (1358–1359) by Duke Rudolf IV of Austria. Rudolf originally claimed the title in the form \"palatinus archidux\" (\"palatine archduke\"). The title was intended to emphasize the claimed precedence (thus \"Arch-\") of the Duchy of Austria, in an effort to put the Habsburgs on an even level with the Prince-Electors of the Holy Roman Empire, as Austria had been passed over when the Golden Bull of 1356 assigned that dignity to the four highest-ranking secular Imperial princes and three Archbishops. Holy Roman Emperor Charles IV refused to recognise the title, as did all the other ruling dynasties of the member countries of the Empire. But Duke Ernest the Iron and his descendants unilaterally assumed the title of \"Archduke\". The archducal title was only officially recognized in 1453 by Emperor Frederick III, when the Habsburgs had solidified their grip on the throne of the \"de jure\" elected Holy Roman Emperor, making it \"de facto\" hereditary. Despite that imperial authorization of the title, which showed a Holy Roman Emperor from the Habsburg dynasty deciding over a title claim of the Habsburg dynasty, many ruling dynasties of the countries which formed the Empire refused to recognize the title \"Archduke\". Ladislaus the Posthumous, Duke of Austria, who died in 1457, never got in his lifetime the imperial authorization to use it, and accordingly, neither he nor anyone in his branch of the dynasty ever used the title. Emperor Frederick III himself simply used the title \"Duke of Austria\", never \"Archduke\", until his death in 1493. The title was first granted to Frederick's younger brother, Albert VI of Austria (d. 1463), who used it at least from 1458. In 1477, Frederick III also granted the title of \"Archduke\" to his first cousin, Sigismund of Austria, ruler of Further Austria (). Frederick's son and heir, the future Emperor Maximilian I, started to use the title, but apparently only after the death of his wife Mary of Burgundy (d. 1482), as \"Archduke\" never appears in documents issued jointly by Maximilian and Mary as rulers in the Low Countries (where Maximilian is still titled \"Duke of Austria\"). The title appears first in documents issued under the joint rule of Maximilian and his son Philip in the Low Countries. \"Archduke\" was initially borne by those dynasts who ruled a Habsburg territory—i.e., only by males and their consorts, appanages being commonly distributed to cadets. But these \"junior\" \"archdukes\" did not thereby become sovereign hereditary rulers, since all territories remained vested in the Austrian crown. Occasionally a territory might be combined with a separate gubernatorial mandate ruled by an archducal cadet.", "section_level": 1}, {"title": "Usage.", "content": "From the 16th century onward, \"Archduke\" and its female form, \"Archduchess\", came to be used by \"all\" the members of the House of Habsburg (e.g. Queen Marie Antoinette of France was born Archduchess Maria Antonia of Austria). Upon extinction of the male line of the Habsburgs and the marriage of their heiress, the Holy Roman Empress-consort Maria Theresa, Queen of Hungary and Archduchess of Austria, to Francis Stephen, Duke of Lorraine, who was elected Holy Roman Emperor, their descendants formed the House of Habsburg-Lorraine. After the dissolution of the Holy Roman Empire this usage was retained in the Austrian Empire (1804–1867) and the Austro-Hungarian Empire (1867–1918). The official use of titles of nobility and of all other hereditary titles, including \"Archduke\", has been illegal in the Republic of Austria for Austrian citizens since the Law on the Abolition of Nobility (\"Gesetz vom 3. April 1919 über die Aufhebung des Adels, der weltlichen Ritter- und Damenorden und gewisser Titel und Würden\"). Thus those members of the Habsburg family who are residents of the Republic of Austria are simply known by their first name(s) and their surname \"Habsburg-Lothringen\". However, members of the family who reside in other countries may or may not use the title, in accordance with laws and customs in those nations. For example, Otto Habsburg-Lothringen (1912–2011), the eldest son of the last Habsburg Emperor, was an Austrian, Hungarian and German citizen. As he lived in Germany, where it is permitted to use hereditary titles as part of the civil surname (including indications of origin, such as \"von\" or \"zu\"), his official civil name was Otto von Habsburg (literally: Otto \"of\" Habsburg), whereas in Austria he was registered as Otto Habsburg. The King of Spain also bears the nominal title of Archduke of Austria as part of his full list of titles, as the Bourbon dynasty adopted all the titles previously held by the Spanish Habsburgs when they took over the Spanish throne. However, \"Archduke\" was never considered by the Spanish Bourbons as a substantial dignity of their own dynasty, but rather as a traditional supplementary title of the Spanish Kings since the days of the Habsburg dynasty on the royal throne (1516–1700).

To focus on an object at infinity, the distance from this single lens to focal plane of the camera (where the sensor or film is respectively) has to be adjusted to this focal length. For example, given a focal length of 500 mm, the distance between lens and focal plane is 500 mm. The farther the focal length is increased, the more the physical length of such a simple lens makes it unwieldy. But such simple lenses are not telephoto lenses, no matter how extreme the focal length – they are known as \"long-focus lenses\". While the optical centre of a simple (\"non-telephoto\") lens is within the construction, the telephoto lens moves the optical centre in front of the construction. While the length of a long-focus lens approximates its focal length, a telephoto lens manages to be shorter than its focal length. E.g., a telephoto lens might have a focal length of 400 mm, while it is shorter than that. A telephoto lens works by having the outermost (i.e. light gathering) element of a much shorter focal length than the equivalent long-focus lens and then incorporating a second set of elements close to the film or sensor plane that extend the cone of light so that it appears to have come from a lens of much greater focal length. The basic construction of a telephoto lens consists of front lens elements that, as a group, have a positive focus. The focal length of this group is shorter than the effective focal length of the lens. The converging rays from this group are intercepted by the rear lens group, sometimes called the \"telephoto group,\" which has a negative focus. The simplest telephoto designs could consist of one element in each group, but in practice, more than one element is used in each group to correct for various aberrations. The combination of these two groups produces a lens assembly that is physically shorter than a long-focus lens producing the same image size. This same property is achieved in camera lenses that combine mirrors with lenses. These designs, called catadioptric,'reflex', or'mirror' lenses,have a curved mirror as the primary objective with some form of negative lens in front of the mirror to correct optical aberrations. They also use a curved secondary mirror to relay the image that extends the light cone the same way the negative lens telephoto group does. The mirrors also fold the light path. This makes them much shorter, lighter, and cheaper than an all refractive lens, but at the cost of some optical compromises due to aberrations caused by the central obstruction from the secondary mirror. The heaviest non-Catadioptric telephoto lens for civilian use was made by Carl Zeiss and has a focal length of 1700 mm with a maximum aperture of, implying a entrance pupil. It is designed for use with a medium format Hasselblad 203 FE camera and weighs.

This allows for greater clearance for other optical or mechanical parts such as the mirror parts in a single-lens reflex camera.

In 1883 or 1884 New Zealand photographer Alexander McKay discovered he could create a much more manageable long-focus lens by combining a shorter focal length telescope objective lens with negative lenses and other optical parts from opera glasses to modify the light cone. Some of his photographs are preserved in the holdings of the Turnbull Library in Wellington, and two of these can be unequivocally dated as having been taken during May 1886. One of McKay’s photographs shows a warship anchored in Wellington harbour about two and a half kilometres away, with its rigging lines and gun ports clearly visible.

The city was also mentioned in Rome since they here produced excellent fabrics that were used in the most exclusive togas. After Rome lost its position as the dominant power in the western Mediterranean, Pollentia was attacked by pirates and several times by the Vandals. Finally, the city was abandoned, and the remaining population left to create a new town at a more protected location. This town became Pollenca and the area where Pollentia stood was left to ruins. After the invasion of the Moors, a farmstead was created very close to where the ancient village of Pollentia had been. The farm was called Alcúdia, which is Arabic for \"on the hill\". In 1229, the Moors were defeated by King James I of Aragon, who overtook the power of the area. In 1298, King James II of Aragon bought the farmstead Alcúdia and founded the new town. A church, a graveyard, a house for priests, and a square were created in the same year. The construction of the walls was also initiated at the same time and finished in 1362. The city plan that was made at the time remains the same for Alcúdia today. During the Renaissance, walls were reconstructed, and a second wall was constructed outside the first one. This wall has since been torn down and only details show where it once was. During the 16th century pirates attacked the city several times. The population shrank, and there was from time to time a risk that the city would be abandoned totally. In 1779 a decision was taken to support the city by constructing a harbour.

The new numbers are, however, used from Denmark and southward, though, as do other European routes within Scandinavia. These two roads are the most conspicuous exceptions to the rule that even numbers signify west-to-east E-roads. Further exceptions are E67, going from Finland to Czech Republic (wrong side of E75 and E77), assigned around year 2000, simply because it was best available number for this new route, most of E63 in Finland (wrong side of E75) E8 in Finland (partly on the wrong side of E12 after a lengthening around 2002) and E82 (Spain and Portugal, wrong side of E80).

Although the town itself is only about two hundred years old, the locality has been inhabited much longer. The first written record dates back to 1273, when there was a village of Úšovice. The springs first appear in a document dating from 1341 where they are called \"the Auschowitzer springs\" belonging to the Teplá Abbey. It was only through the efforts of Dr Josef Nehr, the abbey's physician, who from 1779 until his death in 1820 worked hard to demonstrate the curative properties of the springs, that the waters began to be used for medicinal purposes. The place obtained its current name of Marienbad in 1808; became a watering-place in 1818, and received its charter as a town in 1868. By the early 20th century, approximately 1,000,000 bottles of mineral water were exported annually from Marienbad. The water from the Cross Spring (\"Kreuzquelle\", \"Křížový pramen\") was evaporated and the final product was sold as a laxative under the name of \"sal teplensis\". The modern spa town was founded by the Teplá abbots, namely Karl Kaspar Reitenberger, who also bought some of the surrounding forests to protect them. Under the guidance of gardener Václav Skalník, architect Jiří Fischer, and builder Anton Turner the inhospitable marshland valley was changed into a park-like countryside with colonnades, neoclassical buildings and pavilions around the springs. The name Marienbad first appeared in 1786; since 1865 it has been a town. Then came a second period of growth, the town's Golden Era. Between 1870 and 1914 many new hotels, colonnades and other buildings, designed by Friedrich Zickler, Josef Schaffer, and Arnold Heymann, were constructed or rebuilt from older houses. In 1872 the town got a railway connection with the town of Cheb (Eger) and thus with the whole Austro-Hungarian Empire and the rest of Europe. The town soon became one of the top European spas, popular with notable figures and rulers who often returned there. Among them were such names as Johann Wolfgang Goethe, Frédéric Chopin, Thomas Edison, Richard Wagner or Prince Friedrich of Saxony, King Edward VII of the United Kingdom, the Russian Czar Nicholas II, and Emperor Franz Joseph I and many others. At those times, about 20,000 visitors came every year. Marienbad remained a popular destination between World War I and World War II. After World War II, the ethnic German population of the town was forcibly expelled according to the Potsdam agreement, thereby emptying the town of the majority of its population. After the communist coup-d'état in 1948; it got sealed off from most of its foreign visitors. After the return of democracy in 1989 much effort was put into restoring the town into its original character.

In 1645–46 he served in Hungary against Prince Rákóczy of Transylvania, on the Danube and Neckar against the French, and in Silesia and Bohemia against the Swedes. The victory of Triebel in Silesia won him the rank of \"General of Cavalry\", and at the battle of Zusmarshausen in 1648 his stubborn rearguard fighting rescued the imperials from annihilation. For some years after the Peace of Westphalia Montecuccoli was chiefly concerned with the business of the council of war, though he went to Flanders and England as the representative of the emperor, and to Sweden as the envoy of the pope to Queen Christina, and at Modena his lance was victorious in a great tourney. In 1657, soon after his marriage with Countess Margarethe de Dietrichstein, he was ordered by the Emperor to take part in the Habsburg expedition (as agreed between the King of Poland and the Emperor) against Prince Rákóczy, Charles X Gustav of Sweden and the Cossacks, who had already, in 1655, attacked the Kingdom of Poland in the war known in Poland as \"The Deluge\" or elsewhere as the \"Second Northern War\". During the conflict he was promoted to commanding officer of the division. He became field-marshal in the imperial army and his division, along with Stefan Czarniecki's division, Frederick William's army and Danish forces, participated in the struggle in Denmark against the invading Swedes.

He became a tercio pikeman for the Crown of Spain at the age of sixteen. 1618 saw the outbreak of the Thirty Years' War. Piccolomini was appointed captain of a cavalry regiment in Bohemia, sent by the Grand Duke of Tuscany to the emperor's army. He fought with distinction under Count Charles Bucquoy at the Battle of White Mountain in 1620 and later in Hungary. In 1624 he served for a short time again in the Spanish army and then as lieutenant-colonel of Gottfried Heinrich Graf zu Pappenheim's cuirassier regiment in the war with the Milanese. In 1627 he returned to the Imperial service as colonel and captain of the personal guard of Albrecht von Wallenstein, Duke of Friedland. In this capacity Piccolomini fell into disgrace for attempting to extort money from people of Stargard in Pomerania. But his dedication and contrition saw him returned to the rank of \"colonel of horse and foot\". In 1629 his younger brother, Ascanio Piccolomini, was appointed Archbishop of Siena which secured the older Piccolomini brother a position of influence in the diplomatic world. Italians were at the centre of diplomacy in Europe (due in no small part to the influence of the Roman Catholic Church) and this was even more so the case for a family that had seen two of its members elected to the papal throne (Popes Pius II and Pius III). Wallenstein made use of his subordinate's capacity for negotiation and intrigue. During the Mantuan War, Piccolomini took a prominent part in the dual role of subtle diplomat and plundering soldier of fortune. In 1630 came the invasion of Germany by Gustavus Adolphus of Sweden. Piccolomini was captured and held hostage at Ferrara for helping in unauthorised negotiations for peace with the Swedish Empire. Despite his support for Wallenstein, he was not included in the list of promotions when the Duke resumed action against Saxony, Brandenburg, Sweden and France. Thereafter, Piccolomini served as a colonel under Feldmarschallleutnant Heinrich Holk, a Danish officer, in the battle of Lützen and other operations. Nineteenth-century authors were so impressed by Piccolomini's role in the battle of Lützen that they falsely ascribed to him the command of the entire Imperial left wing.

At the same time, however, Holk, who had played an even more crucial role in holding the Imperial army together at Lützen, was promoted to field marshal at Wallenstein's insistence, much to Piccolomini's chagrin. In the campaign of 1633 Piccolomini was appointed commander of a detachment posted at Königgratz assigned to bar the enemy's advance from Silesia into Bohemia. In May, Wallenstein entered Silesia with the main army in an attempt to compel the electors of Brandenburg and Saxony to join the Holy Roman Empire against the Swedes. Piccolomini was with Wallenstein but disapproved of his policy and joined in the military conspiracy to oust the Duke. On 24 January 1634 Ferdinand II signed a decree dismissing Wallenstein and instructed Count Gallas and Piccolomini to determine a course of action for removing the Duke, but did not specifically demand his death. Nevertheless, the conspiracy developed into a plot to assassinate the Duke; Wallenstein was killed on 25 February 1634 at Cheb Castle. Piccolomini's reward was his marshal's baton, 100,000 gulden and the estate of Náchod in the Orlické mountains in East Bohemia. Piccolomini's part in the assassination was set out in fictionalised form in Friedrich Schiller's play, \"Wallenstein\". On 5 and 6 September of that same year, Piccolomini distinguished himself at the Battle of Nördlingen. By 1635, Piccolomini was again allied with a Spanish army but complained that their laziness and caution ruined every strategy he developed. In 1638 he was made a Count of the Empire. In 1639, having won a great victory over the French (at the relief of Thionville, on 7 July), he was rewarded with elevation to the office of privy councillor and the dukedom of Amalfi from King Philip IV of Spain.

Also in 1925, he published his work in intuitionistic logic, \"On the principle of the excluded middle\", in which he proved that under a certain interpretation, all statements of classical formal logic can be formulated as those of intuitionistic logic. In 1929, Kolmogorov earned his Doctor of Philosophy (Ph.D.) degree, from Moscow State University. In 1930, Kolmogorov went on his first long trip abroad, traveling to Göttingen and Munich, and then to Paris. He had various scientific contacts in Göttingen. First of all with Richard Courant and his students working on limit theorems, where diffusion processes turned out to be the limits of discrete random processes, then with Hermann Weyl in intuitionistic logic, and lastly with Edmund Landau in function theory. His pioneering work, \"About the Analytical Methods of Probability Theory,\" was published (in German) in 1931. Also in 1931, he became a professor at the Moscow State University. In 1933, Kolmogorov published his book, \"Foundations of the Theory of Probability\", laying the modern axiomatic foundations of probability theory and establishing his reputation as the world's leading expert in this field. In 1935, Kolmogorov became the first chairman of the department of probability theory at the Moscow State University. Around the same years (1936) Kolmogorov contributed to the field of ecology and generalized the Lotka–Volterra model of predator-prey systems. In 1936, Kolmogorov and Alexandrov were involved in the political persecution of their common teacher Nikolai Luzin, in the so-called Luzin affair. In a 1938 paper, Kolmogorov \"established the basic theorems for smoothing and predicting stationary stochastic processes\"—a paper that had major military applications during the Cold War. In 1939, he was elected a full member (academician) of the USSR Academy of Sciences. During World War II Kolmogorov contributed to the Russian war effort by applying statistical theory to artillery fire, developing a scheme of stochastic distribution of barrage balloons intended to help protect Moscow from German bombers. In his study of stochastic processes, especially Markov processes, Kolmogorov and the British mathematician Sydney Chapman independently developed the pivotal set of equations in the field, which have been given the name of the Chapman–Kolmogorov equations. Later, Kolmogorov focused his research on turbulence, where his publications (beginning in 1941) significantly influenced the field. In classical mechanics, he is best known for the Kolmogorov–Arnold–Moser theorem, first presented in 1954 at the International Congress of Mathematicians. In 1957, working jointly with his student Vladimir Arnold, he solved a particular interpretation of Hilbert's thirteenth problem. Around this time he also began to develop, and was considered a founder of, algorithmic complexity theory – often referred to as Kolmogorov complexity theory. Kolmogorov married Anna Dmitrievna Egorova in 1942. He pursued a vigorous teaching routine throughout his life, not only at the university level but also with younger children, as he was actively involved in developing a pedagogy for gifted children (in literature, music, and mathematics). At the Moscow State University, Kolmogorov occupied different positions, including the heads of several departments: probability, statistics, and random processes; mathematical logic. He also served as the Dean of the Moscow State University Department of Mechanics and Mathematics. In 1971, Kolmogorov joined an oceanographic expedition aboard the research vessel \"Dmitri Mendeleev\". He wrote a number of articles for the \"Great Soviet Encyclopedia.\" In his later years, he devoted much of his effort to the mathematical and philosophical relationship between probability theory in abstract and applied areas. Kolmogorov died in Moscow in 1987, and his remains were buried in the Novodevichy cemetery. A quotation attributed to Kolmogorov is [translated into English]: \"Every mathematician believes that he is ahead of the others. The reason none state this belief in public is because they are intelligent people.\" Vladimir Arnold once said: \"Kolmogorov – Poincaré – Gauss – Euler – Newton, are only five lives separating us from the source of our science\".", "section_level": 2}, {"title": "Awards and honours.", "content": "Kolmogorov received numerous awards and honours both during and after his lifetime: The following are named in Kolmogorov's honour:", "section_level": 1}, {"title": "Bibliography.", "content": "A bibliography of his works appeared in Textbooks:", "section_level": 1}], "src_summary": "Andrey Nikolaevich Kolmogorov (, 25 April 1903 – 20 October 1987) was a Soviet mathematician who made significant contributions to the mathematics of probability theory, topology, intuitionistic logic, turbulence, classical mechanics, algorithmic information theory and computational complexity.", "tgt_summary": null, "id": 4971875} {"src_title": "Pertinax", "tgt_title": null, "src_document": [{"title": "Early life.", "content": "His career before becoming emperor is documented in the \"Historia Augusta\" and confirmed in many places by existing inscriptions.

In the Parthian war that followed, he was able to distinguish himself, which resulted in a string of promotions, and after postings in Britain (as military tribune of the Legio VI \"Victrix\") and along the Danube, he served as a procurator in Dacia. He suffered a setback as a victim of court intrigues during the reign of Marcus Aurelius, but shortly afterwards he was recalled to assist Claudius Pompeianus in the Marcomannic Wars. In 175, he received the honor of a suffect consulship and until 185, Pertinax was governor of the provinces of Upper and Lower Moesia, Dacia, Syria and finally governor of Britain. During the 180s, Pertinax took a pivotal role in the Roman Senate until the praetorian prefect Sextus Tigidius Perennis forced him out of public life. He was recalled after three years to Britain, where the Roman army was in a state of mutiny. He tried to quell the unruly soldiers there but one legion attacked his bodyguard, leaving Pertinax for dead. When he was forced to resign in 187, the reason given was that the legions had grown hostile to him because of his harsh rule.

The plot was carried out by the Praetorian prefect Quintus Aemilius Laetus, Commodus' mistress Marcia, and his chamberlain Eclectus. After the murder had been carried out, Pertinax, who was serving as urban prefect at this time, was hurried to the Praetorian Camp and proclaimed emperor the following morning. His short reign (86 days) was an uneasy one. He attempted to emulate the restrained practices of Marcus Aurelius, and made an effort to reform the alimenta but he faced antagonism from many quarters. Ancient writers detail how the Praetorian Guard expected a generous donativum on his ascension, and when they were disappointed, agitated until he produced the money, selling off Commodus' property, including the concubines and youths Commodus kept for his sexual pleasures. He reformed the Roman currency dramatically, increasing the silver purity of the denarius from 74% to 87% – the actual silver weight increasing from 2.22 grams to 2.75 grams. Pertinax attempted to impose stricter military discipline upon the pampered Praetorians. In early March he narrowly averted one conspiracy by a group to replace him with the consul Quintus Sosius Falco while he was in Ostia inspecting the arrangements for grain shipments. The plot was betrayed; Falco himself was pardoned but several of the officers behind the coup were executed. On 28 March 193, Pertinax was at his palace when, according to the \"Historia Augusta\", a contingent of some three hundred soldiers of the Praetorian Guard rushed the gates (two hundred according to Cassius Dio). Ancient sources suggest that they had received only half their promised pay. Neither the guards on duty nor the palace officials chose to resist them. Pertinax sent Laetus to meet them, but he chose to side with the insurgents instead and deserted the emperor. Although advised to flee, he then attempted to reason with them, and was almost successful before being struck down by one of the soldiers.

Dio refers to him as \"an excellent and upright man\" who displayed \"not only humaneness and integrity in the imperial administrations, but also the most economical management and the most careful consideration for the public welfare.\" Dio's approval is not unqualified, however. He acknowledges that while some would call Pertinax's decision to confront the soldiers that would wind up killing him \"noble\", others would call it \"senseless\". He is also critical of Pertinax's judgment when it came to the speed with which he tried to reform the excesses of the reign of Commodus, suggesting that a more tempered approach would have been less likely to result in his murder. Pertinax is discussed in \"The Prince\" by Niccolò Machiavelli. When discussing the importance of a prince not being hated, Machiavelli provides Pertinax as an example of how it is as easy for a ruler to be hated for good actions as for bad ones. Though describing him as a good man, Machiavelli considered Pertinax's attempt to reform a soldiery that had become \"accustomed to live licentiously\" a mistake, as it inspired their hatred of him, which led to his overthrow and death. Pertinax is described by David Hume in his essay \"Of the Original Contract\" as an \"excellent prince\" possessing an implied modesty when, on the arrival of soldiers who had come to proclaim him emperor, he believed that Commodus had ordered his death.

Born in 1924 in the Free City of Danzig (now Gdańsk, Poland), with an adult's capacity for thought and perception, he decides never to grow up when he hears his father declare that he would become a grocer. Gifted with a piercing shriek that can shatter glass or be used as a weapon, Oskar declares himself to be one of those \"clairaudient infants\", whose \"spiritual development is complete at birth and only needs to affirm itself\". He retains the stature of a child while living through the beginning of World War II, several love affairs, and the world of postwar Europe. Through all this, a toy tin drum, the first of which he received as a present on his third birthday, followed by many replacement drums each time he wears one out from over-vigorous drumming, remains his treasured possession; he is willing to commit violence to retain it. Oskar considers himself to have two \"presumptive fathers\"—his mother's husband Alfred Matzerath, a member of the Nazi Party, and her cousin and lover Jan Bronski, a Danzig Pole who is executed for defending the Polish Post Office in Danzig during the German invasion of Poland. Oskar's mother having died, Alfred marries Maria, a woman who is secretly Oskar's first mistress. After marrying Alfred, Maria gives birth to Kurt, whom Oskar thereafter refers to as his son. But Oskar is disappointed to find that the baby persists in growing up, and will not join him in ceasing to grow at the age of three. During the war, Oskar joins a troupe of performing dwarfs who entertain the German troops at the front line. But when his second love, the diminutive Roswitha, is killed by Allied troops in the invasion of Normandy, Oskar returns to his family in Danzig where he becomes the leader of a criminal youth gang (akin to the Edelweiss Pirates). The Russian army soon captures Danzig, and Alfred is shot by invading troops after he goes into seizures while swallowing his party pin to avoid being revealed as a Nazi. Oskar bears some culpability for both of his presumptive fathers' deaths since he leads Joseph Bronski to the Polish Post Office in an effort to get his drum repaired and since he returns Alfred Matzerath's Nazi party pin while the latter is being interrogated by Soviet soldiers. After the war Oskar, his widowed stepmother, and their son have to leave the now Polish city of Danzig and move to Düsseldorf, where he models in the nude and works engraving tombstones. Mounting tensions compel Oskar to live apart from Maria and Kurt; he decides on a flat owned by the Zeidlers. Upon moving in, he falls in love with Sister Dorothea, a neighbor, but he later fails to seduce her. During an encounter with fellow musician Klepp, Klepp asks Oskar how he has an authority over the judgement of music. Oskar, willing to prove himself once and for all, picks up his drum and sticks despite his vow to never play again after Alfred's death, and plays a measure on his drum. The ensuing events lead Klepp, Oskar, and Scholle, a guitarist, to form the Rhine River Three jazz band. They are discovered by Mr. Schmuh, who invites them to play at the Onion Cellar club. After a virtuoso performance, a record company talent seeker discovers Oskar the jazz drummer and offers a contract. Oskar soon achieves fame and riches.

If a light source is in the lens' angle of view, a lens hood will hardly have any effect, but the light does not have to cause lens flare. It is sufficient that stray light from a bright light source enters the lens.

These more complex shapes take into account the final image's shape and aspect ratio. This allows the lens hood to block stray light with the longer portions of the lens hood, while allowing more light into the corners of the image through the shorter portions of the hood, thereby reducing the amount of mechanical vignetting (reduction of light around the periphery) in the final image. The geometry of a lens hood is dependent on three things: Ideally, lens hoods should increase in length, and therefore in efficiency, as the focal length of the lens increases and the angle of view reduces. Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood (away from the end of the lens) cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens. Maximum aperture also affects the shape of a lens hood. As the aperture gets larger the amount of light and consequentially the amount of the frame the sensor \"sees\" increases. This can be seen when comparing two lens hoods of the same focal length but with differing apertures – compare the lens hood of a telephoto 4 lens with that of the same lens but with a maximum aperture of 2.8. Correctly made rectangular or square lens hoods are generally more efficient than cylindrical or conical ones because those shapes closely resemble the shape of the photograph. However, rectangular or square lens hoods should not be used with zoom lenses whose front elements rotate as the focal length is changed, as the hood will rotate as well, blocking parts of the angle of view. The same also applies to petal lens hoods. For these types of lenses, only cylindrical or conical lens hoods will work effectively. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself. Lens hoods with an extending bellows design (much like the bellows of a medium or large format camera) can be adjusted for depth.

He called on the Church to renounce its claim and return ownership to the city government so as not to be tainted by possession—renunciation of worldliness being one of his primary teachings. He was condemned at the Second Lateran Council in 1139 and forced from Italy. According to the chronicler Otto of Freising, Arnold had studied in Paris under the tutelage of the reformer and philosopher Pierre Abélard. He took to Abélard's philosophy of reform ways. The issue came before the Synod of Sens in 1141 and both Arnold and Abélard's positions were overruled by Bernard of Clairvaux. Arnold stood alone against the church's decision after Abélard's capitulation; he returned to Paris, where he continued to teach and preach against Bernard. As a consequence he was then commanded to silence and exiled by Pope Innocent II. He took refuge first in Zürich and then probably in Bavaria. His writings were also condemned to be burned as a further measure, though the condemnation is the only evidence that he had actually written anything. Arnold continued to preach his radical ideas concerning apostolic poverty. Arnold, who is known only from the vituperative condemnation of his foes, was declared to be a demagogue; his motives were impugned. Having returned to Italy after 1143, Arnold made his peace in 1145 with Pope Eugene III, who ordered him to submit himself to the mercy of the Church in Rome. When he arrived, he found that Giordano Pierleoni's followers had asserted the ancient rights of the commune of Rome, taken control of the city from papal forces, and founded a republic, the Commune of Rome. Arnold sided with the people immediately and, after Pierleoni's deposition, soon rose to the intellectual leadership of the Commune, calling for liberties and democratic rights. Arnold taught that clergy who owned property had no power to perform the Sacraments. He succeeded in driving Pope Eugene into exile in 1146, for which he was excommunicated on 15 July 1148. When Pope Eugene returned to the city in 1148, Arnold continued to lead the blossoming republic despite his excommunication. In summing up these events, Caesar Baronius called Arnold \"the father of political heresies\", while Edward Gibbon later expressed his view that \"the trumpet of Roman liberty was first sounded by Arnold.\" After Pope Eugene's death, Pope Adrian IV swiftly took steps to regain control of Rome. He allied with Frederick Barbarossa, who took Rome by force in 1155 after a Holy Week interdict and forced Arnold again into exile. Arnold was seized by Imperial forces and tried by the Roman Curia as a rebel. Importantly, he was never accused of heresy. Faced with the stake, he refused to recant any of his positions. Convicted of rebellion, Arnold was hanged in June and his body burnt. Because he remained a hero to large sections of the Roman people and the minor clergy, his ashes were cast into the Tiber, to prevent his burial place becoming venerated as the shrine of a martyr.

As a day job, he translated literature into Russian (19 books in 6 years), then worked as a correspondent for a newspaper. In the autumn of 1933, Mandelstam composed the poem \"Stalin Epigram\", which he read at a few small private gatherings in Moscow. The poem was a sharp criticism of the \"Kremlin highlander\". Six months later, in 1934, Mandelstam was arrested. But, after interrogation about his poem, he was not immediately sentenced to death or the Gulag, but to exile in Cherdyn in the Northern Ural, where he was accompanied by his wife.

The ancient name of the city also is said to be derived from the Egyptian symbol for \"trade\", or \"market\". Because the Ancient Egyptians oriented themselves toward the origin of the life-giving waters of the Nile in the south, and as Swenett was the southernmost town in the country, Egypt always was conceived to \"open\" or begin at Swenett. The city stood upon a peninsula on the right (east) bank of the Nile, immediately below (and north of) the first cataract of the flowing waters, which extend to it from Philae. Navigation to the delta was possible from this location without encountering a barrier. The stone quarries of ancient Egypt located here were celebrated for their stone, and especially for the granitic rock called Syenite. They furnished the colossal statues, obelisks, and monolithal shrines that are found throughout Egypt, including the pyramids; and the traces of the quarrymen who worked in these 3,000 years ago are still visible in the native rock. They lie on either bank of the Nile, and a road, in length, was cut beside them from Syene to Philae. Swenett was equally important as a military station as a place of traffic. Under every dynasty it was a garrison town; and here tolls and customs were levied on all boats passing southwards and northwards. Around 330, the legion stationed here received a bishop from Alexandria; this later became the Coptic Diocese of Syene. The city is mentioned by numerous ancient writers, including Herodotus, Strabo, Stephanus of Byzantium, Ptolemy, Pliny the Elder, Vitruvius, and it appears on the Antonine Itinerary. It may also be mentioned in the Book of Ezekiel and the Book of Isaiah. The latitude of the city that would become Aswan – located at 24° 5′ 23′′ – was an object of great interest to the ancient geographers. They believed that it was seated immediately under the tropic, and that on the day of the summer solstice, a vertical staff cast no shadow. They noted that the sun's disc was reflected in a well at noon. This statement is only approximately correct; at the summer solstice, the shadow was only of the staff, and so could scarcely be discerned, and the northern limb of the Sun's disc would be nearly vertical.

He studied with private tutors and took an interest in natural history, later attending the University of Halle and the University of Göttingen. In 1760, he moved to the University of Leiden and passed his doctor's degree at the age of 19. Pallas travelled throughout the Netherlands and to London, improving his medical and surgical knowledge. He then settled at The Hague, and his new system of animal classification was praised by Georges Cuvier. Pallas wrote \"Miscellanea Zoologica\" (1766), which included descriptions of several vertebrates new to science which he had discovered in the Dutch museum collections. A planned voyage to southern Africa and the East Indies fell through when his father recalled him to Berlin. There, he began work on his \"Spicilegia Zoologica\" (1767–80). In 1767, Pallas was invited by Catherine II of Russia to become a professor at the St Petersburg Academy of Sciences and, between 1768 and 1774, he led an expedition to central Russian provinces, Povolzhye, Urals, West Siberia, Altay, and Transbaikal, collecting natural history specimens for the academy. He explored the Caspian Sea, the Ural and Altai Mountains and the upper Amur River, reaching as far eastward as Lake Baikal. The regular reports which Pallas sent to St Petersburg were collected and published as \"Reise durch verschiedene Provinzen des Russischen Reichs\" (Journey through various provinces of the Russian Empire) (3 vols., 1771–1776). They covered a wide range of topics, including geology and mineralogy, reports on the native peoples and their religions, and descriptions of new plants and animals. In 1776, Pallas was elected a foreign member of the Royal Swedish Academy of Sciences. Pallas settled in St Petersburg, becoming a favourite of Catherine II and teaching natural history to the Grand Dukes Alexander and Constantine. He was provided with the plants collected by other naturalists to compile the \"Flora Rossica\" (1784–1815), a Russian flora, and started work on his \"Zoographica Rosso-Asiatica\" (1811–31), a zoography of Russia and Asia. He also published an account of Johann Anton Güldenstädt's travels in the Caucasus. The Empress bought Pallas's large natural history collection for 2,000 rubles, 500 more than his asking price, and allowed him to keep them for life. During this period, Pallas helped plan the Mulovsky expedition, which was cancelled in October 1787. Between 1793 and 1794, Pallas led a second expedition to southern Russia, visiting the Crimea and the Black Sea. He was accompanied by his daughter (by his first wife who had died in 1782) and his new wife, an artist, servants, and a military escort. In February 1793, they travelled to Saratov and then downriver to Tsaritsyn. They explored the country to the east, and in August travelled along the banks of the Caspian Sea and into the Caucasus Mountains. In September, they travelled to the Crimea, wintering in Simferopol. Pallas spent early 1794 exploring to the southeast, and in July travelled up the valley of the Dnieper, arriving back in St Petersburg in September. Pallas gave his account of the journey in his \"P. S. Pallas Bemerkungen auf einer Reise in die Südlichen Statthalterschaften des Russischen Reichs\" (1799–1801). Catherine II gave him a large estate at Simferopol, where Pallas lived until the death of his second wife in 1810.

It favored the transfer of public and private funds outside of Spain keeping all of the foreign exchanges in the hands of the Royal Treasury, enriching the State. It is considered the predecessor to the Bank of San Carlos, introduced during the reign of Charles III. Commerce was stimulated in the Americas, in an attempt to end the monopoly in the Indies and eliminate the injustices of colonial commerce. Ferdinand leaned toward registered ships rather than fleets of ships. The new system consisted of the substitution of the fleets and galleons so that a Spanish ship, previously authorized, could conduct trade freely in the Americas. This increased the revenues and decreased the fraud. Even so, this system provoked many protests among merchants in the private sector. According to Ensenada, a powerful navy was fundamental to power of an overseas empire and aspirations of being respected by France and Great Britain. He increased the navy's budget and expanded the capacity of the shipyards of Cádiz, Ferrol, Cartagena and Havana which marked a commitment to extending the naval policies already underway in his predecessor's reign. Church relations were really tense from start of the reign of Philip V because of the recognition of Charles of Austria as the king of Spain by the pope. A regalist policy was maintained that pursued as much political as fiscal objectives and whose decisive achievement was the Concord of 1753.

The American banking system had to recall money from Europe, and cancel the credits that made the Young Plan possible. Moreover, the downfall of imports and exports affected the rest of the world. By 1933, almost two-thirds of world trade had vanished. A new trade policy was set with the Smoot–Hawley Tariff Act. The latter was influenced by nationalism and the adopted economic policy. Unemployment soared to 33.7% in 1931 in Germany, and 40% in 1932. Under such circumstances, U.S. President Herbert Hoover issued a public statement that proposed a one-year moratorium on the payments. He managed to assemble support for the moratorium from 15 nations by July 1931. But the adoption of the moratorium did little to slow economic decline in Europe. Germany was gripped by a major banking crisis. A final effort was made at the Lausanne Conference of 1932. Here, representatives from Great Britain, France, Italy, Belgium, Germany and Japan gathered to come to an agreement. By that time it was clear that the deepening depression had made it impossible for Germany to resume its reparations payments. They agreed: Hoover made the obligatory public statement about the lack of any connection between reparations and war debts, however in December 1932, the U.S. Congress rejected the Allied war debt reduction plan, which technically meant that the war reparations and debt reverted to the debt reduction previously granted Germany by the 1929 Young Plan. However, the system had collapsed, and Germany did not resume payments. Once the National Socialist government consolidated power, the debt was repudiated and Germany made no further payments. By 1933, Germany had made World War I reparations of only one eighth of the sum required under the Treaty of Versailles, and owing to the repudiated American loans the United States in effect paid \"reparations\" to Germany. The plan ultimately failed, not because of the U.S. Congress' refusal to go along, but because it became irrelevant upon Hitler's rise to power. After Germany’s defeat in World War II, an international conference (London Agreement on German External Debts, 1953) decided that Germany would pay the remaining debt only after the country was reunified. Nonetheless, West Germany paid off the principal by 1980; then in 1995, after reunification, the new German government announced it would resume payments of the interest. Germany was due to pay off the interest to the United States in 2010, and to other countries in 2020. In 2010, \"Time\" reported that Germany made \"final reparations-related payment for the Great War on Oct. 3, nearly 92 years after the country's defeat by the Allies.\" This agreement had been preceded by bitter diplomatic struggles, and its acceptance aroused nationalist passions and resentment.

A coalition was formed of various conservative groups under the leadership of Alfred Hugenberg, the head of the German National People's Party. One of the groups that joined this coalition was Adolf Hitler and the National Socialist German Workers Party. The coalition's goal was the enactment of the \"Freiheitsgesetz\" (\"Liberty Law\"). This law would renounce all reparations and make it a criminal offense for any German official to cooperate in their collection. It would also renounce the German acknowledgement of \"war guilt\" and the occupation of German territory which were also terms of the Treaty of Versailles. Under the terms of the German constitution, if ten percent of the eligible voters in the country signed a petition in favor of a proposed law, the Reichstag had to put the matter to a vote. If the Reichstag voted against the law, the proposal would automatically be put to a national referendum. If fifty percent of the people voted in favor of it, it would become a law. The Liberty Law proposal was officially put forth on October 16, 1929. The National Socialists and other groups held large public rallies to collect signatures. The government opposed the Liberty Law and staged demonstrations against it. However, the coalition succeeded in collecting enough names to put the proposal before the Reichstag.

In the subsequent popular vote on December 22, the Liberty Law referendum, voter turnout was only 14.9%, although 94.5% of the votes cast (13.8% of registered voters) were in favor of the proposed law. While the Liberty Law was not enacted in 1929, the campaign for it was a major factor in bringing Hitler and the National Socialists into the political mainstream. Following the defeat, Hitler denounced Hugenberg and said the loss was a result of his poor leadership.

In 1830 the German process of manufacture was introduced into England, while exports of from China gradually stopped. In 1832, a form of German silver was also developed in Birmingham, England. After the modern process for the production of electroplated nickel silver was patented by the Elkington brothers in Sheffield in 1840, the development of electroplating caused nickel silver to become widely used. It formed an ideal, strong and bright substrate for the plating process. It was also used unplated in applications such as cutlery.", "section_level": 1}, {"title": "Uses.", "content": "Nickel silver first became popular as a base metal for silver-plated cutlery and other silverware, notably the electroplated wares called EPNS (electroplated nickel silver). It is used in zippers, better-quality keys, costume jewelry, for making musical instruments (e.g., flutes, clarinets), and is preferred for the track in electrically powered model railway layouts, as its oxide is conductive. It is widely used in the production of coins (e.g. Portuguese escudo and the former GDR marks). Its industrial and technical uses include marine fittings and plumbing fixtures for its corrosion resistance, and heating coils for its high electrical resistance. In the nineteenth century, particularly after 1868, North American Plains Indian jewelers were able to easily acquire sheets of German silver. They used them to cut, stamp, and cold hammer a wide range of accessories and also horse gear. Continuing into the present, Plains metalsmiths have used German silver for pendants, pectorals, bracelets, armbands, hair plates, \"conchas\" (oval decorative plates for belts), earrings, belt buckles, necktie slides, stickpins, \"dush-tuhs\", and tiaras. Nickel silver is the metal of choice among contemporary Kiowa and Pawnee metalsmiths in Oklahoma. Many of the metal fittings on modern higher-end equine harness and tack are of nickel silver. Early in the twentieth century, German silver was used by automobile manufacturers before the advent of steel sheet metal; for example, the famous Rolls-Royce Silver Ghost of 1907. After about 1920, its use became widespread for pocketknife bolsters, due to its machinability and corrosion resistance. Prior to this point, the most common metal was iron. Musical instruments, including the flute, saxophone, trumpet, and French horn, can be made of nickel silver. Many professional-level French horns are entirely made of nickel silver. Some saxophone manufacturers, such as Keilwerth, offer saxophones made of nickel silver (Shadow model); these are far rarer than traditional lacquered brass saxophones. Student-level flutes and piccolos are also made of silver-plated nickel silver, although upper-level models are likely to use sterling silver. Nickel silver produces a bright and powerful sound quality; an additional benefit is that the metal is harder and has more corrosion resistance than brass. Because of its hardness, it is the most commonly used material for woodwind keys. Most clarinets, flutes, oboes and similar wind instruments have nickel silver keys, normally silver-plated. It is used to produce the tubes (called staples) onto which oboe reeds are tied. Many parts of brass instruments are made of nickel silver, such as tubes, braces or valve mechanism. Trombone slides of many manufacturers offer lightweight nickel silver (LT slide) option for faster slide action and weight balance. It was used in the construction of the National tricone resophonic guitar. The frets of guitar, mandolin, banjo, bass, and related string instruments are typically made of nickel silver. Nickel silver is sometimes used as ornamentation on the great highland bagpipe. Nickel silver is also used in art. The Dutch sculptor Willem Lenssinck has made several objects in German silver.

The strong influence of Irish literati on the script can be seen in the distinctively cló-Gaelach (Irish style) forms of the letters, especially a, e, d, g, s, and t. Carolingian minuscule was created partly under the patronage of the Emperor Charlemagne (hence Carolingian). Charlemagne had a keen interest in learning, according to his biographer Einhard (here with apices): Temptábat et scríbere, tabulásque et códicellós ad hoc in lectó sub cervícálibus circumferre solébat, ut, cum vacuum tempus esset, manum litterís effigiendís adsuésceret, sed parum successit labor praeposterus ac séró incohátus. As a part of Charlemagne's educational and religious reforms, he decreed that every church and monastery should have a copy of Jerome's Vulgate Bible. Charlemagne wanted to make the Vulgate Bible more readable for preachers and easier to copy for scribes. Thus, Marcia Colish explains, Charlemagne looked first to Anglo-Saxon England for a scholar to head his court school, finding him in Alcuin (). He assigned to Alcuin the correction of the Vulgate. In conjunction with this project, and later in his career when he became abbot of Tours, Alcuin invented a new style of handwriting, the Caroline minuscule. This script was far more legible than earlier medieval hands and an improvement on Roman book hands, since it provided spaces between the words, more extensive punctuation, and a hierarchy of hands, with capitals used for titles, a mix of capitals and lower-case letters for subtitles or chapter headings, and lower case for the body of the text. With the newly corrected Bible, pastors would be able to base their teaching and preaching on what it actually said. Although Charlemagne was never fully literate, he understood the value of literacy and a uniform script in running his empire. Charlemagne sent for the English scholar Alcuin of York to run his palace school and scriptorium at his capital, Aachen. Efforts to supplant Gallo-Roman and Germanic scripts had been under way before Alcuin arrived at Aachen, where he was master from 782 to 796, with a two-year break. The new minuscule was disseminated first from Aachen, of which the Ada Gospels provided classic models, and later from the influential scriptorium at Marmoutier Abbey (Tours), where Alcuin withdrew from court service as an abbot in 796 and restructured the scriptorium.", "section_level": 1}, {"title": "Characteristics.", "content": "Carolingian minuscule was uniform, with rounded shapes in clearly distinguishable glyphs, disciplined and above all, legible. Clear capital letters and spaces between words became standard in Carolingian minuscule, which was one result of a campaign to achieve a culturally unifying standardization across the Carolingian Empire. Traditional charters, however, continued to be written in a Merovingian \"chancery hand\" long after manuscripts of Scripture and classical literature were being produced in the minuscule hand. Documents written in a local language, like Gothic or Anglo-Saxon rather than Latin, tended to be expressed in traditional local script. Carolingian script generally has fewer ligatures than other contemporary scripts, although the \"et\" (\"&\"), \"æ\", \"rt\", \"st\", and \"ct\" ligatures are common. The letter \"d\" often appears in an uncial form with an ascender slanting to the left, but the letter \"g\" is essentially the same as the modern minuscule letter, rather than the previously common uncial \"\". Ascenders are usually \"clubbed\" – they become thicker near the top. The early period of the script, during Charlemagne's reign in the late 8th century and early 9th, still has widely varying letter forms in different regions. The uncial form of the letter \"a\", similar to a double \"c\" (\"cc\"), is still used in manuscripts from this period. There is also use of punctuation such as the question mark, as in Beneventan script of the same period. The script flourished during the 9th century, when regional hands developed into an international standard, with less variation of letter forms. Modern glyphs, such as \"s\" and \"v\", began to appear (as opposed to the \"long \"s\"\" \"s\" and \"u\"), and ascenders, after thickening at the top, were finished with a three-cornered wedge. The script began to evolve slowly after the 9th century. In the 10th and 11th centuries, ligatures were rare and ascenders began to slant to the right and were finished with a fork.

It reached far afield: the 10th century Freising manuscripts, which contain the oldest Slovene language, the first Roman-script record of any Slavic language, are written in Carolingian minuscule. In Switzerland, Carolingian was used in the Rhaetian and Alemannic minuscule types. Manuscripts written in Rhaetian minuscule tend to have slender letters, resembling Insular script, with the letters and, and ligatures such as, showing similar to Visigothic and Beneventan. Alemannic minuscule, used for a short time in the early 9th century, is usually larger and broader, very vertical compared to the slanting Rhaetian type. In Austria, Salzburg was the major centre of Carolingian script, while Fulda, Mainz, and Würzburg were the major centres in Germany. German minuscule tends to be oval-shaped, very slender, and slants to the right. It has uncial features as well, such as the ascender of the letter slanting to the left, and vertical initial strokes of and. In northern Italy, the monastery at Bobbio used Carolingian minuscule beginning in the 9th century. Outside the sphere of influence of Charlemagne and his successors, however, the new legible hand was resisted by the Roman Curia; nevertheless the Romanesca type was developed in Rome after the 10th century. The script was not taken up in England and Ireland until ecclesiastic reforms in the middle of the 10th century; in Spain a traditionalist Visigothic hand survived; and in southern Italy a 'Beneventan minuscule' survived in the lands of the Lombard duchy of Benevento through the 13th century, although Romanesca eventually also appeared in southern Italy.", "section_level": 1}, {"title": "Role in cultural transmission.", "content": "Scholars during the Carolingian Renaissance sought out and copied in the new legible standardized hand many Roman texts that had been wholly forgotten.

Finally, the male lays a spermatophore, a sperm capsule covered in gossamer, which the female takes into her body via her ovipositor to fertilize her eggs. The female lays groups of fewer than 60 eggs at once, deposited in small crevices. The eggs are oval-shaped, whitish, about long, and take between two weeks and two months to hatch. A silverfish usually lays fewer than 100 eggs in her lifetime. When the nymphs hatch, they are whitish in colour, and look like smaller adults. As they moult, young silverfish develop a greyish appearance and a metallic shine, eventually becoming adults after three months to three years.

It was conquered in 928 by the German King Henry I, but returned to Slavic rule after the rebellion of 983. In 1156, the Ascanian count Albert the Bear took possession of the region and is believed to have established a fortress here, from which the name Spandau originated. It was around this fortress that the city of Spandow developed, becoming the centre of the entire region. It was first mentioned as \"Spandowe\" in 1197 in a deed of Otto II, Margrave of Brandenburg – 40 years earlier than the Cölln part of medieval Berlin. Spandau was given city rights in 1232. During the Ascanian Rule the construction of the Spandau Citadel began, which was completed between 1559 and 1594 by Joachim II of Brandenburg. In 1558 the village of Gatow became part of Spandau. During the Thirty Years' War Spandau was surrendered to the Swedes in 1634. In 1806, after the Battle of Jena and Auerstedt, French troops under Napoleon took possession of the city and stayed there until 1807. In 1812, Napoleon returned and the Spandau Citadel was besieged in 1813 by Prussian and Russian troops.

This flag later resurfaced several other times, it was used as the flag of the United Baltic Duchy. In the era of the crusades, the particular geographic domain of the contemporary Estonia's location (the Eastern Baltic shores) was proclaimed to be \"Land of Mary\", the Land of the Virgin Mary, \"Terra Mariana\" in Latin. (The region more to the South, the then-Prussia, was named the Land of St Peter). When creating its flag, the generic Teutonic banner was adapted so as to include the colors of the flag of St Mary. Mary being the \"Virgin/Queen of Heaven\", her flag consists of blue representing the heaven/sky, and white, the color of purity. The \"Marian flag\" itself, the flag of St Mary (St Maria), has two fields, white over blue. This original flag is still to be found in the flag of the Baltic Germans, and the flag of Pomerania (Province of Pomerania (1815–1945)). The Marian flag is still popular in Poland. It is also the flag of the Cathedral of St Mary in Luxembourg. This flag is also taken for the background in the San Marino (St Marinus) banner. The merging of the Teutonic cross with the Marian colors resulted in the Terra mariana pattern. The pattern is today used in the coat of arms of the Jungingen family (Ulrich von Jungingen, notably, the Grand Master of the Teutonic Order active in the Baltic domain). It is also used in the coat of arms of the German town of Jungingen. The State of the German Order of the Cross ceased to exist in 1561. In 1860 the students of the Baltic-Prussian extraction studying in Germany (in Danzig, in Karlsruhe) established a society, the Baltica-Borussia (Prussia) student organisation (\"corporation\"). The coat of arms of that corporation was based on the known pattern of colours and their arrangement associated with the region and its German past (the coat of arms also incorporated the German eagle). The corporation also adopted a flag. As the idea behind the French revolutionary tricolours demanded that flags be composed of three fields of equal width (representing the equality of the citizens), so was the old Terra Mariana flag transformed into a tricolour (technically, a triband). In 1881 the Society of Estonian Students at the University of Tartu (Estonia) was formed, a similar tricolour was constructed. Yet by that time the selection of the particular colours was also attributed to the Finnish flag, and the colours were ascribed symbolic meanings. The Estonian flag was therefore officially adopted first as a student organisation flag on 17 September 1881 by the constituent assembly of the first Estonian national student Corps \"Vironia\" (modern Estonian Students Society) in the city of Tartu.

The design was based on the banner of the Senussi dynasty from Cyrenaica, which consisted of a black field and star and crescent design, and was later used as the flag of the region. Omar Faiek Shennib, Chief of the Royal Diwans, Vice President of the National Assembly and Minister of Defense under King Idris Al Senussi is credited in the memoirs of Adrian Pelt, UN commissioner for Libya (1949 to 1951) for the design of the original flag of Libya. According to Pelt: \"during deliberations of the Libyan National Constitutional Convention, a paper drawing of a proposed national flag was presented to the convention by Omar Faiek Shennib [distinguished member of the delegation from Cyrenaica]. The design was composed of three colors; red, black and green, with a white Crescent and Star centered in the middle black stripe. Mr. Shennib informed the delegates that this design had met the approval of His Highness Emir of Cyrenaica, King Idris Al Senussi [later to become King of Libya]. The assembly subsequently approved that design.\" This flag represented Libya from its independence in 1951 until the 1969 Libyan coup d'état. The symbolism of the star and crescent in the flag of the Kingdom of Libya was explained in an English language booklet, \"The Libyan Flag & The National Anthem\", issued by the Ministry of Information and Guidance of the Kingdom of Libya (year unknown) as follows: \"The crescent is symbolic of the beginning of the lunar month according to the Muslim calendar. It brings back to our minds the story of Hijra [migration] of our Prophet Mohammed from his home in order to spread Islam and teach the principles of right and virtue. The Star represents our smiling hope, the beauty of aim and object and the light of our belief in God, in our country, its dignity and honour which illuminate our way and puts an end to darkness.\" In 2011, interviews with Ibtisam Shennib and Amal Omar Shennib, Omar Faeik Shennib's only two remaining children, were cited as confirming Pelt's account of the origin of the flag. Ibtisam Shennib recalled the morning her father brought a draft of the flag to the breakfast table and showed it to her and her siblings, explaining the original intent behind the selection of the flag's colours and symbols. According to Omar Faiek Shennib, \"red was selected for the blood sacrificed for the freedom of Libya, black to remember the dark days that Libyans lived under the occupation of the Italians and green to represent its primary wealth, agriculture, [Libya once being referred to as the 'agricultural basket' or 'breadbasket' of the Ottoman Empire] and the future prosperity of the country. The star and crescent were placed within the black central strip of the flag as a reference to the Senussi flag and the role of King Idris in leading the country to independence\". During the Libyan Civil War against the rule of Muammar Gaddafi, the 1951–69 flag — as well as various makeshift versions without the crescent and star symbol, or without the green stripe — came back into use in areas held by the Libyan opposition and by protesters at several Libyan diplomatic missions abroad. The National Transitional Council, formed on 27 February 2011, adopted the flag previously used in the Kingdom of Libya between 1951 and 1969 as the \"emblem of the Libyan Republic\". The flag was officially defined in article three of the Libyan Draft Constitutional Charter for the Transitional Stage: The national flag shall have the following shape and dimensions: Its length shall be double its width, its shall be divided into three parallel coloured stripes, the uppermost being red, the centre black and lowest green, the black stripe shall be equal in area to the other two stripes together and shall bear in its centre a white crescent, between the two extremities of which there shall be a five-pointed white star.

On 21 March, the flag was flown by the Permanent Mission of Libya to the United Nations and appeared on their official website, and thereafter in late August by the Arab League and by Libya's own telecommunications authority, the Libya Telecom & Technology, on its own website. In the following months many other Libyan embassies replaced the green flag of Gaddafi with the tricolour flag.

The first historically recorded samovar-makers were the Russian Lisitsyn brothers, Ivan Fyodorovich and Nazar Fyodorovich. From their childhood they were engaged in metalworking at the brass factory of their father, Fyodor Ivanovich Lisitsyn. In 1778 they made a samovar, and the same year Nazar Lisitsyn registered the first samovar-making factory in Russia. They may not have been the inventors of the samovar, but they were the first documented samovar-makers, and their various and beautiful samovar designs became very influential throughout the later history of samovar-making. These and other early producers lived in Tula, a city known for its metalworkers and arms-makers. Since the 18th century Tula has been also the main center of Russian samovar production, with \"tul'sky samovar\" being the brand mark of the city. A Russian saying equivalent to \"carrying coal to Newcastle\" is \"to travel to Tula with one's own samovar\". Although Central Russia and Ural region were among the first Samovar producers, over time several samovar producers emerged all over Russia, which gave the somovar its different local characteristics. By the 19th century samovars were already a common feature of Russian tea culture. They were produced in large numbers and exported to Central Asia and other regions. The samovar was an important attribute of Russian households and taverns to tea-drinking. It was used by all classes, from the poorest peasants up to the most well-suited people. The Russian expression \"to have a sit by the samovar\" means to have a leisurely talk while drinking tea from a samovar. In everyday use samovars were an economical permanent source of hot water in older times. Various slow-burning items could be used for fuel, such as charcoal or dry pinecones. When not in use, the fire in the samovar pipe faintly smouldered. As needed it could be quickly rekindled with the help of bellows.

His father was a printer. He studied Hebrew and Talmud with an Orthodox rabbi. Scholem met Walter Benjamin in Munich in 1915, when the former was seventeen years old and the latter was twenty-three. They began a lifelong friendship that ended when Benjamin committed suicide in 1940 in the wake of Nazi persecution. Scholem dedicated his book \"Major Trends in Jewish Mysticism\" (\"Die jüdische Mystik in ihren Hauptströmungen\"), based on lectures 1938–1957, to Benjamin. In 1915 Scholem enrolled at the Frederick William University in Berlin (today, Humboldt University), where he studied mathematics, philosophy, and Hebrew. There he met Martin Buber, Shmuel Yosef Agnon, Hayim Nahman Bialik, Ahad Ha'am, and Zalman Shazar. In Berlin, Scholem befriended Leo Strauss and corresponded with him throughout his life. He studied mathematical logic at the University of Jena under Gottlob Frege. He was in Bern in 1918 with Benjamin when he met Elsa (Escha) Burchhard, who became his first wife. Scholem returned to Germany in 1919, where he received a degree in semitic languages at the Ludwig Maximilian University of Munich. Together with Benjamin he established a fictitious school - the University of Muri. Scholem wrote his doctoral thesis on the oldest known kabbalistic text, \"Sefer ha-Bahir\". Drawn to Zionism and influenced by Buber, he immigrated in 1923 to the British Mandate of Palestine. He became a librarian, and eventually head of the Department of Hebrew and Judaica at the National Library. Scholem's brother Werner was a member of the ultra-left \"Fischer-Maslow Group\" and the youngest ever member of the Reichstag, representing the Communist Party (KPD) in the German parliament. He was expelled from the party and later murdered by the Nazis during the Third Reich. Gershom Scholem, unlike his brother, was vehemently opposed to both Communism and Marxism. In 1936, he married his second wife, Fania Freud. Scholem died in Jerusalem, where he is buried next to his wife in the Sanhedria Cemetery. Jürgen Habermas delivered the eulogy.", "section_level": 1}, {"title": "Academic career.", "content": "He became a lecturer at the Hebrew University of Jerusalem. Scholem taught the Kabbalah and mysticism from a scientific point of view and became the first professor of Jewish mysticism at the university in 1933, working in this post until his retirement in 1965, when he became an emeritus professor. Scholem directly contrasted his historiographical approach on the study of Jewish mysticism with the approach of the 19th-century school of the \"Wissenschaft des Judentums\" (\"Science of Judaism\"), which sought to submit the study of Judaism to the discipline of subjects such as history, philology, and philosophy. According to Jeremy Adler, Scholem's thinking was \"both recognizably Jewish and deeply German,\" and \"changed the course of twentieth-century European thought.\" Jewish mysticism was seen as Judaism's weakest scholarly link. Scholem told the story of his early research when he was directed to a prominent rabbi who was an expert on Kabbalah. Seeing the rabbi's many books on the subject, Scholem asked about them, only to be told: \"This trash? Why would I waste my time reading nonsense like this?\" (Robinson 2000, p. 396) The analysis of Judaism carried out by the \"Wissenschaft\" school was flawed in two ways, according to Scholem: It studied Judaism as a dead object rather than as a living organism; and it did not consider the proper \"foundations\" of Judaism, the non-rational force that, in Scholem's view, made the religion a living thing. In Scholem's opinion, the mythical and mystical components were at least as important as the rational ones, and he thought that they, rather than the minutiae of Halakha, were the truly living core of Judaism. In particular, he disagreed with what he considered to be Martin Buber's personalization of Kabbalistic concepts as well as what he argued was an inadequate approach to Jewish history, Hebrew language, and the land of Israel. In the \"Weltanschauung\" of Scholem, the research of Jewish mysticism could not be separated from its historical context. Starting from something similar to the \"Gegengeschichte\" of Friedrich Nietzsche he ended up including less normative aspects of Judaism in the public history. Specifically, Scholem thought that Jewish history could be divided into three periods: The notion of the three periods, with its interactions between rational and irrational elements in Judaism, led Scholem to put forward some controversial arguments. He thought that the 17th century messianic movement, known as Sabbatianism, was developed from the Lurianic Kabbalah. In order to neutralize Sabbatianism, Hasidism had emerged as a Hegelian synthesis. Many of those who joined the Hasidic movement, because they had seen in it an Orthodox congregation, considered it scandalous that their community should be associated with a heretical movement. In the same way, Scholem produced the hypothesis that the source of the 13th century Kabbalah was a Jewish gnosticism that preceded Christian gnosticism. The historiographical approach of Scholem also involved a linguistic theory. In contrast to Buber, Scholem believed in the power of the language to invoke supernatural phenomena. In contrast to Walter Benjamin, he put the Hebrew language in a privileged position with respect to other languages, as the only language capable of revealing the divine truth. Scholem considered the Kabbalists as interpreters of a pre-existent linguistic revelation.", "section_level": 1}, {"title": "Debate with Hannah Arendt.", "content": "In the aftermath of the Eichmann trial in Jerusalem, Scholem sharply criticised Hannah Arendt's book, \"\" and decried her lack of \"ahavath Yisrael\" (solidarity with the Jewish people). Arendt responded that she never loved any collective group, and that she does not love the Jewish people but was only part of them. The bitter fight, which was exchanged in various articles, made Scholem break off ties with Arendt and refuse to forgive her. Scholem wrote to Hans Paeschke that he \"knew Hannah Arendt when she was a socialist or half-communist and...when she was a Zionist. I am astounded by her ability to pronounce upon movements in which she was once so deeply engaged, in terms of a distance measured in light years and from such sovereign heights.” Various other Israeli and Jewish academics also broke off ties with Arendt, claiming that her lack of solidarity with the Jewish people in their time of need was appalling, along with her victimization of various Nazis. Before the Eichmann trial, Scholem also opposed Arendt's interpretation (in letters and the introduction to \"Illuminations\") of Walter Benjamin as a Marxist thinker who predated the New Left.

Instead, influenced by the process philosophy of Alfred North Whitehead, he claimed that the fundamental units of anthropology were processes of human life and interaction. Because these are by definition characterised by constant flux, what calls for explanation is the occurrence of stability. Why, Radcliffe-Brown asked, would some patterns of social practices repeat themselves and even seem to become fixed? He reasoned that this would at least require that other practices must not conflict with them too much; and that in some cases, it may be that practices grow to support each other, a notion he called 'coadaptation', deriving from the biological term. Functional analysis, then, was just the attempt to explain stability by discovering how practices fit together to sustain that stability; the 'function' of a practice was just its role in sustaining the overall social structure, insofar as there was a stable social structure (Radcliffe-Brown 1957).

Instead, he argued for the use of the comparative method to find regularities in human societies and thereby build up a genuinely scientific knowledge of social life. To that end, Radcliffe-Brown argued for a 'natural science of society'. He claimed that there was an independent role for social anthropology here, separate from psychology, though not in conflict with it. This was because psychology was to be the study of individual mental processes, while social anthropology was to study processes of interaction between people (social relations).

One proposal was for a tournament based upon the format of the European Cup, but with national cup winners rather than league champions taking part, which could run alongside that competition. The inaugural Cup Winners' Cup was held in the 1960–61 season and was basically a semi-official pilot tournament. However the initial reaction to the competition's creation was unenthusiastic on the part of many of Europe's top clubs – many European associations did not have domestic cup competitions at the time and in those countries that did, the cup competition was generally held in low esteem and often not taken seriously by the bigger clubs. It was essentially only in England, Scotland and to a lesser extent Germany and Spain that the domestic cup was considered especially prestigious. Many were sceptical about the viability of a European tournament for cup winners and many of the bigger clubs eligible to contest the first CWC turned down the chance to enter, such as Atlético Madrid of Spain and AS Monaco of France. Ultimately the inaugural CWC was contested by just 10 clubs (with Fiorentina of Italy winning the two-legged final against the Scottish team Rangers) but the games were generally well attended and the response from the public and the media to the new tournament was positive and enthusiastic. For the tournament's second season in 1961–62, UEFA took over the running of all aspects of the competition and this time all the clubs eligible to enter accepted the opportunity. By 1968, all UEFA member nations had set up domestic cup competitions due to the success of the Cup Winners' Cup. UEFA regarded it as the second most prestigious competition, behind the European Cup (later the UEFA Champions League) and ahead of the Fairs Cup (later the UEFA Cup). Therefore, a team qualified for both the European Cup and the Cup Winners' Cup would play in the European Cup, whereas a team qualified for both the UEFA Cup and the Cup Winners' Cup would play in the Cup Winners' Cup. Nevertheless, many commentators and fans regarded the Cup Winners' Cup as weaker than the UEFA Cup, which had more and better teams from the stronger European leagues. In the 1985–86 season, English clubs were banned from European competition as a result of Heysel Stadium disaster. Consequently, Manchester United, Everton, Coventry City, Wimbledon and Liverpool were prevented from competing in the Cup Winners' Cup until the beginning of the 1990–91 season.

Many of the bigger teams who would previously have entered the Cup Winners' Cup were now gaining entry to the Champions League instead by finishing second in their domestic league – such as Cup Winners' Cup holders Barcelona in 1997–98 and Bayern Munich and PSV Eindhoven in 1998–99 – and this greatly weakened the Cup Winners' Cup. At the time of the Champions League expansion, UEFA also considered expanding the Cup Winners' Cup from 32 teams to 64 by allowing a second team to enter from many countries, although by what qualification criteria the second entrants would be determined were never settled upon – ultimately UEFA did not make any of these changes to the Cup Winners' Cup. By the late 1990s, the Cup Winners' Cup had come to be seen as a second-rate competition with only one or two big name teams available to enter each year and the interest in the tournament from both major clubs and the public dropped.

Pupienus's career was allegedly impressive, serving a number of important posts during the reign of the Severan dynasty throughout the late 2nd and early 3rd centuries. This included assignment as Proconsul of the senatorial propraetorial provinces of Bithynia et Pontus, Achaea, and Gallia Narbonensis.

According to Edward Gibbon (drawing on the narratives of Herodian and the \"Historia Augusta\"), the choice was sensible, as: the mind of Maximus [Pupienus] was formed in a rougher mould [than that of Balbinus]. By his valour and abilities he had raised himself from the meanest origin to the first employments of the state and army.

The two colleagues had both been consul... and, since the one was sixty and the other seventy-four years old, they had both attained the full maturity of age and experience. However, factions within the Senate who had hoped to profit from the accession of the Gordians manipulated the people and the Praetorian Guard to agitate for the elevation of Gordian III as their imperial colleague. Leaving his senior colleague Balbinus in charge of the civil administration at Rome, sometime during late April Pupienus marched to Ravenna, where he oversaw the campaign against Maximinus, recruiting German auxiliary troops who had served under him whilst he was in Germania. After Maximinus was assassinated by his soldiers just outside Aquileia, Pupienus despatched both Maximinus's troops and his own back to their provinces (along with a considerable donative) and returned to Rome with his newly-acquired German bodyguard. Balbinus, in the meantime, had failed to keep public order in the capital. The sources suggest that Balbinus suspected Pupienus of using his German bodyguard to supplant him, and they were soon living in different parts of the Imperial palace. This meant that they were at the mercy of disaffected elements in the Praetorian Guard, who resented serving under Senate-appointed emperors, and now plotted to kill them. Pupienus, becoming aware of the threat, begged Balbinus to call for the German bodyguard. Balbinus, believing that this news was part of a plot by Pupienus to have him assassinated, refused, and the two began to argue just as the Praetorians burst into the room.

He was hailed as successor to the throne of Denmark in 1542, and of Norway in 1548. Unlike his father, King Frederick II was strongly affected by military ideals. Already as a young man, he made friendships with German war princes. In 1552, Steward of the Realm, Peder Oxe (1520–1575), had been raised to Councillor of State (\"Rigsraad\"). During the spring of 1557, Oxe and the King had quarreled over a mutual property exchange. Failing to compromise matters with the King, Oxe had fled to Germany in 1558. However, financial difficulties arose during the stress of the Northern Seven Years' War. King Frederick II won his first victory with the conquest of Dithmarschen in Schleswig-Holstein under Johan Rantzau, during the summer of 1559. From his predecessor, he inherited the Livonian War. In 1560, he installed his younger brother, Magnus of Holstein (1540–1583), in the Bishopric of Ösel–Wiek. King Frederick II largely tried to avoid conflict in Livonia and consolidated amicable relations with Tsar Ivan IV of Russia in the 1562 Treaty of Mozhaysk. His brother Magnus was later made titular King of Livonia, as a vassal of Tsar Ivan IV. King Frederick's competition with Sweden for supremacy in the Baltic broke out into open warfare in 1563, the start of the Northern Seven Years' War, the dominating conflict of his rule. He tried in vain to conquer Sweden, which was ruled by his cousin, King Eric XIV. It developed into an extremely expensive war of attrition in which the areas of Scania were ravaged by the Swedes, and Norway was almost lost. During this war, King Frederick II led his army personally on the battlefield, but without much result. The conflict damaged his relationship with his noble councillors; however, the later Sture Murders of 24 May 1567 by the insane King Eric XIV in Sweden, eventually helped stabilize the situation in Denmark. After state finances collapsed during the years 1566 to 1567, King Frederick II called Peder Oxe home to address the kingdom's economy. The taking over of Danish administration and finances by the able councillor, provided a marked improvement for the national treasury. Councillors of experience, including Niels Kaas, Arild Huitfeldt, and Christoffer Valkendorff, took care of the domestic administration. Subsequently, government finances were put in order and Denmark's economy improved. One of the chief expedients of the improved state of affairs was the raising of the Sound Dues. Oxe, as lord treasurer, reduced the national debt considerably and redeemed portions of crown lands. After King John III of Sweden, King Eric's successor, refused to accept a peace favoring Denmark in the Treaties of Roskilde (1568), the ongoing war dragged on until it was ended by a status quo peace in the Treaty of Stettin (1570), that let Denmark save face but also show limits of Danish military power. After the war, King Frederick II kept the peace without giving up his attempt of trying to expand his prestige as a naval ruler. His foreign politics were marked by a moral support of the Protestant powers – but at the same time by a strict neutrality. A period of affluence and growth followed in Danish history. In 1567, King Frederick II founded Fredrikstad in Norway. Frederik II Upper Secondary School in Fredrikstad, one of the largest schools of its kind in Norway, is named after Frederick. He also rebuilt Kronborg in Elsinore from a medieval fortress into a magnificent Renaissance castle, between 1574 and 1585. In 1585, he visited Norway as king when he came to Båhus. He was a major patron and close personal friend of the famous astronomer, Tycho Brahe (whose step-father, Jørgen Thygesen Brahe, had rescued the King from drowning, catching pneumonia and dying as a result).

Magdalenian tool culture is characterised by regular blade industries struck from carinated cores. The Magdalenian epoch is divided into six phases generally agreed to have chronological significance. The earliest phases are recognised by the varying proportion of blades and specific varieties of scrapers, the middle phases marked by the emergence of a microlithic component (particularly the distinctive denticulated microliths), and the later phases by the presence of uniserial (phase5) and biserial 'harpoons' (phase6) made of bone, antler and ivory. Debate continues about the nature of the earliest Magdalenian assemblages, and it remains questionable whether the Badegoulian culture is the earliest phase of Magdalenian culture. Similarly, finds from the forest of Beauregard near Paris have been suggested as belonging to the earliest Magdalenian. The earliest Magdalenian sites are in France. The Epigravettian is a similar culture appearing at the same time. Its known range extends from southeast France to the western shores of the Volga River, Russia, with many sites in Italy. The later phases of Magdalenian culture are contemporaneous with the human re-settlement of north-western Europe after the Last Glacial Maximum during the Late Glacial Maximum. As hunter gatherers, Magdalenians did not re-settle permanently in northwest Europe, instead following herds and seasons. By the end of the Magdalenian epoch, lithic technology shows a pronounced trend toward increased microlithisation. The bone harpoons and points have the most distinctive chronological markers within the typological sequence. As well as flint tools, Magdalenians are known for their elaborate worked bone, antler and ivory that served both functional and aesthetic purposes, including perforated batons. The sea shells and fossils found in Magdalenian sites may be sourced to relatively precise areas and have been used to support hypotheses of Magdalenian hunter-gatherer seasonal ranges, and perhaps trade routes. In northern Spain and south-west France this tool culture was superseded by the Azilian culture. In northern Europe it was followed by variants of the Tjongerian techno-complex.

In 1584, Hassler became the first of many German composers of the time who went to Italy to continue their studies; he arrived in Venice during the peak of activity of the Venetian school, the composers who wrote in the resplendent polychoral style, which was soon to become popular outside its native city. Hassler was already familiar with some of this music, as numerous prints had circulated in Germany due to the interest of Leonhard Lechner, who was associated with Orlandus Lassus in Munich. While in Venice, Hassler became friends with Giovanni Gabrieli, with whom he composed a wedding motet for Georg Gruber, a Nuremberg merchant living in Venice, in 1600. Together they studied with Andrea Gabrieli, Giovanni's uncle. Under Andrea, Hassler received instruction in composition and organ playing. Following Andrea Gabrieli's death, Hassler returned to Germany in the latter part of 1585, moving to Augsburg where he served as an organist to Octavian II Fugger, a nobleman there. The Augsburg years were extremely creative for him; in addition he became well known as a composer and organist at this time, though his influence was limited because he was a Protestant in an area which was still heavily Catholic. Hassler was not only a composer, but also an active organist and a consultant to organ builders. In 1596, Hassler, along with 53 other organists, was given the opportunity to examine a new instrument with 59 stops at the Schlosskirche, Groningen. Hassler was continually recognized for his expertise in organ design, and was often called upon as the examiner of new instruments. Using his extensive organ background, Hassler stepped into the world of mechanical instrument construction and developed a clockwork organ that was later sold to Emperor Rudolf II. In 1602, Hassler returned to Nuremberg where he became the \"Kapellmeister,\" or director of town music. While there, he was appointed \"Kaiserlicher Hofdiener\" in the court of Rudolf II. In 1604, he took a leave of absence and traveled to Ulm, where he was wed to Cordula Claus. Four years later, Hassler moved to Dresden where he served as the electoral chamber organist to the Elector Christian II of Saxony, and eventually as \"Kapellmeister.\" By this time, Hassler had already developed the tuberculosis that would claim his life in June 1612. After he died, Michael Praetorius and Heinrich Schütz were appointed in his place.", "section_level": 1}, {"title": "Style.", "content": "Hassler was one of the first to bring the innovations of the Venetian style across the Alps. Through his songs, “in the manner of foreign madrigal and canzonets,” and the \"Lustgarten\", Hassler brought to Germany the \"villanelle\", \"canzonette\", and dance songs of Gastoldi and Orazio Vecchi. As the first great German composer to undertake an “Italian Journey,” Hassler's influence was one of the reasons for the Italian domination over German music and for the common trend of German musicians finishing their education in Italy. While musicians of the stature of Lassus had been working in Germany for years, they represented the older school, the \"prima pratica\", the fully developed and refined Renaissance style of polyphony; in Italy new trends were emerging which were to define what was later called the Baroque era. Musicians such as Hassler, and later Schütz, carried the concertato style, the polychoral idea, and the freely emotional expression of the Venetians into the German culture, creating the first and most important Baroque development outside of Italy. Though Hassler was Protestant, he wrote many masses and directed the music for Catholic services in Augsburg. While in the service of Octavian Fugger, Hassler dedicated both his \"Cantiones sacrae\" and a book of masses for four to eight voices to him. Due to the demands of the Catholic patrons, and his own Protestant beliefs, Hassler's compositions represented a skillful blend of both religions’ music styles that allowed his compositions to function in both contexts. Thus, many of Hassler's works could be used both in the Roman Catholic Church and the Lutheran. During his time in Augsburg, Hassler only produced two works that were specifically meant for the Lutheran church. Under the commission of the free city of Nuremberg, the \"Psalmen simpliciter\" was composed in 1608, and was dedicated to the city. Hassler also produced the \"Psalmen und christliche Gesänge, mit vier Stimmen auf die Melodeien fugweis komponiert\" in 1607 and dedicated it to Elector Christian II of Saxony. Stylistically, Hassler's early works exhibit reflections of the influence of Lassus, while his later works are marked by the impressions left on him by his studies in Italy. After returning from Italy, Hassler incorporated polychoral techniques, textural contrasts and occasional chromaticism in his compositions. His later masses were characterized by light melodies juxtaposed with the grace and fluidity of the madrigalian dance songs; thus creating a charming sacred style that was more sonorous than it was profound. His secular music—madrigals, canzonette, and songs among the vocal, and ricercars, canzonas, introits and toccatas among the instrumental—show many of the advanced techniques of the Gabrielis in Italy, but with a somewhat more restrained character, and always attentive to craftsmanship and beauty of sound. However, Hassler's greatest success in combining the German and Italian compositional styles existed in his \"lieder.\" In 1590, Hassler released his first publication, a set of twenty-four, four-part \"canzonette\". The \"Lustgarten neuer teutscher Gesang, Balletti, Galliarden und Intraden\", which contains thirty-nine vocal and eleven instrumental pieces, is Hassler's most renowned collection of \"lieder.\" Within this work, Hassler published dance collections for four, five, or six string or wind instruments with voice and without continuo. He also composed \"Mein G'müt ist mir verwirret\", a five-part piece. Its melody was later combined with the text \"O Haupt voll Blut und Wunden\" of Paul Gerhardt, in which form it was used by Bach in his St Matthew Passion. Bach also employed the melody as a counterpoint to the Aria, \"Komm,Du Susse Todesstunde\", in Cantata BWV 161 and used it once again as the final chorale melody in that same cantata. Along with many of his contemporaries, Hassler sought to blend the Italian virtuoso style with the traditional style prevalent in Germany. This was accomplished in the chorale motet by employing the thorough bass continuo and including instrumental and solo ornamentation. Hassler's motets exhibit this blend of the old and the new in the way they reflect both the influence of Lassus and the two four-part chorus style of the Gabrielis. Hassler is considered to be one of the most important German composers of all time. His use of the innovative Italian techniques, coupled with traditional, conservative German techniques allowed his compositions to be fresh without the modern affective tone. His songs presented a combined vocal and instrumental literature that did not make use of the continuo, or only provided it as an option, and his sacred music introduced the Italian polychoral structures that would later influence many composers leading into the Baroque era.", "section_level": 1}], "src_summary": "Hans Leo Hassler (in German, Hans Leo Haßler) (baptized 26 October 1564 – 8 June 1612) was a German composer and organist of the late Renaissance and early Baroque eras, elder brother of composer Jakob Hassler.

Nonetheless, Gaston fled again to Lorraine and, in a secret ceremony in the presence of her family at Nancy during the night of 2 – 3 January 1632, Gaston took the princess Marguerite as his wife. Because he had not obtained the prior permission of his elder brother, the king – one of his many acts of defiance – the couple could not appear at the French court and the marriage was kept secret. But in November of that year, Henri II, Duke of Montmorency, on his way to the scaffold, betrayed Gaston, his former co-conspirator, and Louis XIII and Richelieu learnt of the elopement. The king had his brother's marriage declared null and void by the Parlement of Paris in September 1634 and, despite the protest of Pope Urban VIII, the Assembly of the French clergy held in September 1635 that a \"prince du sang\" could enter matrimony only with permission of the king – consistent with French sovereignty and custom.

Schär (2010) proposed that Gallus may have been of Irish descent but born and raised in the Alsace. According to the 9th-century hagiographies, Gallus as a young man went to study under Comgall of Bangor Abbey. The monastery at Bangor had become renowned throughout Europe as a great centre of Christian learning. Studying in Bangor at the same time as Gall was Columbanus, who with twelve companions, set out about the year 589.

He accompanied Columbanus on his voyage up the Rhine River to Bregenz but when in 612 Columbanus travelled on to Italy from Bregenz, Gall had to remain behind due to illness and was nursed at Arbon. He remained in Alemannia, where, with several companions, he led the life of a hermit in the forests southwest of Lake Constance, near the source of the river Steinach. Cells were soon added for twelve monks whom Gall carefully instructed. Gall was soon known in Switzerland as a powerful preacher. When the See of Constance became vacant, the clergy who assembled to elect a new Bishop were unanimously in favour of Gall. He, however, refused, pleading that the election of a stranger would be contrary to Church law. Some time later, in the year 625, on the death of Eustasius, abbott of Luxeuil, a monastery founded by Saint Columbanus, members of that community were sent by the monks to request Saint Gall to undertake the government of the monastery.

After receiving his musical education, from 1587 he served as organist at the Marienkirche in Frankfurt. From 1592/3 he served at the court in Wolfenbüttel, under the employ of Henry Julius, Duke of Brunswick-Lüneburg. He served in the duke's State Orchestra, first as organist and later (from 1604) as \"Kapellmeister\" (court music director). His first compositions appeared around 1602/3. Their publication primarily reflects the care for music at the court of Gröningen. The motets of this collection were the first in Germany to make use of the new Italian performance practices; as a result, they established him as a proficient composer. These \"modern\" pieces mark the end of his middle creative period. The nine parts of his \"Musae Sioniae\" (1605–10) and the 1611 published collections of liturgical music (masses, hymns, magnificats) follow the German Protestant chorale style. With these, at the behest of a circle of orthodox Lutherans, he followed the Duchess Elizabeth, who ruled the duchy in the duke's absence. When the duke died in 1613 and was succeeded by Frederick Ulrich, Praetorius retained his post in Wolfenbüttel. But he also began working at the court of John George I, Elector of Saxony at Dresden as \"Kapellmeister von Haus aus\" (nonresident music director). There he was responsible for festive music and was exposed to the latest Italian music, including the polychoral works of the Venetian School. His subsequent development of the form of the chorale concerto, particularly the polychoral variety, resulted directly from his familiarity with the music of such Venetians as Giovanni Gabrieli. The solo-voice, polychoral, and instrumental compositions Praetorius prepared for these events mark the high period of his artistic creativity.

While Praetorius made some refinements to figured-bass practice and to tuning practice, his importance to scholars of the 17th century derives from his discussions of the normal use of instruments and voices in ensembles, the standard pitch of the time, and the state of modal, metrical, and fugal theory. His meticulous documentation of 17th-century practice was of inestimable value to the early-music revival of the 20th century. His expansive but unfinished treatise, \"Syntagma Musicum\", appeared in three volumes (with appendix) between 1614 and 1620. The first volume (1614), titled \"Musicae Artis Analecta\", was written mostly in Latin, and regarded the music of the ancients and of the church. The second (\"De Organographia\", 1618) regarded the musical instruments of the day, especially the organ; it was one of the first theoretical treatises written in the vernacular. The third (\"Termini Musicali\", 1618), also in German, regarded the genres of composition and the technical essentials for professional musicians.

In December 1607 his troops occupied the city, and vigorous steps were taken to restore the supremacy of Catholicism. Some Protestant princes, alarmed at this action, formed the Protestant Union to defend their interests, which was answered in 1609 by the establishment of the Catholic League, in the formation of which Maximilian took an important part. Under his leadership an army was set on foot, but his policy was strictly defensive and he refused to allow the League to become a tool in the hands of the House of Habsburg. Dissensions among his colleagues led the duke to resign his office in 1616, but the approach of trouble brought about his return to the League about two years later. Having refused to become a candidate for the imperial throne in 1619, Maximilian was faced with the complications arising from the outbreak of war in Bohemia. After some delay he made a treaty with Ferdinand II, Holy Roman Emperor in October 1619, and in return for large concessions placed the forces of the League at the emperor's service. Anxious to curtail the area of the struggle, he made a treaty of neutrality with the Protestant Union, and occupied Upper Austria as security for the expenses of the campaign. On 8 November 1620 his troops under Johann Tserclaes, Count of Tilly defeated the forces of Frederick, King of Bohemia and Count Palatine of the Rhine, at the Battle of White Mountain near Prague. Subsequently Ferdinand II released Upper Austria as a pawn for Maximilian until 1628. In spite of the arrangement with the Union, Tilly then devastated the Rhenish Palatinate, and in February 1623 Maximilian was formally invested with the electoral dignity and the attendant office of imperial steward, which had been enjoyed since 1356 by the Counts Palatine of the Rhine. After receiving the Upper Palatinate and restoring Upper Austria to Ferdinand, Maximilian became leader of the party which sought to bring about Albrecht von Wallenstein's dismissal from the imperial service. At the Diet of Regensburg (1630) Ferdinand was compelled to assent to this demand, but the sequel was disastrous both for Bavaria and its ruler. Attempting to remain neutral during the war, Maximilian signed the secret Treaty of Fontainebleau (1631) with the Kingdom of France, but this proved worthless. Early in 1632 Gustavus Adolphus of Sweden marched into the duchy and occupied Munich, and Maximilian could only obtain the assistance of the Imperial troops by placing himself under the orders of Wallenstein, now restored to the command of the emperor's forces. The ravages of the Swedes and their French allies induced the elector to enter into negotiations for peace with the Swedes and Cardinal Cardinal Richelieu of France. He also wooed the Protestants by proposing modifications to the Edict of Restitution of 1629, but these efforts were abortive. In September 1638 Baron Franz von Mercy was made master-general of ordnance in the army of Bavaria, then the second largest army in the Holy Roman Empire. Mercy and Johann von Werth as lieutenant field-marshal fought with varying success France and Sweden. In March 1647 Maximilian concluded the Truce of Ulm (1647) with France and Sweden, but the entreaties of Ferdinand III, Holy Roman Emperor led him to disregard his undertaking. Bavaria was again ravaged, and the elector's forces were defeated in May 1648 at the Battle of Zusmarshausen. The Peace of Westphalia soon put an end to the struggle.

From its foundation, the undisciplined Order tended to ignore its supposed vassalage to the bishops. In 1218, Albert asked King Valdemar II of Denmark for assistance, but Valdemar instead arranged a deal with the Brotherhood and conquered northern Estonia (now known as Danish Estonia) for Denmark. The Brotherhood had its headquarters at Fellin (Viljandi) in present-day Estonia, where the walls of the Master's castle stand.

A great deal of the fort's excavation work was carried out on the canal side, sheltered from view and a convenient location to load excavated spoil into barges to be taken away economically.

This was in contrast with French thinking for the contemporary Maginot Line fortifications, which were based on the dispersed \"fort palmé\" concept, with no clearly defined perimeter, a lesson learned from the experiences of French and Belgian forts in World War I. The new Belgian forts, while more conservative in design than the French \"ouvrages\", included several new features as a result of World War I experience. The gun turrets were less closely grouped. Reinforced concrete was used in place of plain mass concrete, and its placement was done with greater care to avoid weak joints between pours. Ventilation was greatly improved, including an air filtration system for protection against gas attack, magazines were deeply buried and protected, and sanitary facilities and general living arrangements for the troops were given careful attention. Eben-Emael and Battice featured 120mm and 75mm guns, giving the fort the ability to bombard targets across a wide area of the eastern Liège region. Fort Eben-Emael occupies a large hill just to the east of Eben-Emael village (now part of Bassenge) and bordering the Albert Canal. The irregularly-shaped fort is about in the east-west dimension, and about in the north-south dimension. It was more heavily armed than any other in the PFL I.

Most of the fort's defenses were lightly manned and taken by complete surprise. Much of the fort's defensive armament was destroyed in a few minutes. The \"Fallschirmjäger\" were able to penetrate one of the 75 mm turrets, killing some defenders and containing the rest in the lower sections of the fortress. The attackers were unable to penetrate further inside the underground galleries, but the garrison was unable to dislodge them from the surface of the fort. The fortress surrendered one day later, when the paratroopers were reinforced by the German 151st Infantry Regiment.

The Germans had planned the capture of the fort well in advance. In preparation they had practised assaulting a full-scale mock up of the fort's exterior in occupied Czechoslovakia using the recently built and captured border fortifications that were modeled to a large degree on western designs. Adolf Hitler himself conceived a plan to take over the fort by getting men onto it by using gliders to overcome the problem of concentrating an airdrop on a small target, and utilizing the new top secret shaped charge (also called \"hollow charge\") bombs to penetrate the cupolas. Good espionage and superior planning, combined with unpreparedness on the Belgian side, helped make the execution of Hitler's top secret plan a swift and overwhelming success. The capture of Eben-Emael involved the first utilization of gliders for the initial attack and the first use of hollow charge devices in war. The gliders, led by First Lieutenant Rudolf Witzig, landed on the roof of the fortress and being totally silent, took the defenders by complete surprise. They were able to use the hollow charges to destroy or disable the gun cupolas. They also used a flamethrower against machine guns. The Belgians did destroy one of the key bridges, preventing it from being used by the Germans but also preventing a relieving force from aiding the fortress.

Studies have shown, however, that individual, separate witness testimony is often flawed, and parts of it can be meaningless. That can occur because of flaws in eyewitness identification (such as faulty observation and recollection, or bias) or because a witness is lying. If several people witness a crime, it is probative to look for similarities in their collective descriptions to substantiate the facts of an event but to keep in mind the contrasts between individual descriptions. One study involved an experiment, in which subjects acted as jurors in a criminal case. Jurors heard a description of a robbery-murder, a prosecution argument, and then an argument for the defense. Some jurors heard only circumstantial evidence; others heard from a clerk who claimed to identify the defendant. In the former case, 18% percent found the defendant guilty, but in the latter case, 72% found the defendant guilty (Loftus 1988). Police lineups in which the eyewitness picks out a suspect from a group of people in the police station are often grossly suggestive, and they give the false impression that the witness remembered the suspect. In another study, students watched a staged crime. An hour later they looked through photos. A week later they were asked to pick the suspect out of lineups. 8% of the people in the lineups were mistakenly identified as criminals. 20% of the innocent people whose photographs were included were mistakenly identified (University of Nebraska 1977). Weapon focus effects in which the presence of a weapon impairs memory for surrounding details is also an issue. Another study looked at 65 cases of \"erroneous criminal convictions of innocent people.\" In 45% of the cases, eyewitness mistakes were responsible. The formal study of eyewitness memory is usually undertaken within the broader category of cognitive processes, the different ways in which we make sense of the world around us. That is done by employing the mental skills at one's disposal like thinking, perception, memory, awareness, reasoning, and judgment. Although cognitive processes can be only inferred and cannot be seen directly, they all have very important practical implications within a legal context. If one were to accept that the way people think, perceive, reason, and judge is not always perfect, it becomes easier to understand why cognitive processes and the factors influencing the processes are studied by psychologists in matters of law, one being the grave implications that this imperfection can have within the criminal justice system.

The first of these, the Pyramid at Meidum, collapsed in antiquity, while the second, the Bent Pyramid, had the angle of its inclination dramatically altered from 54 to 43 degrees part-way through construction.

When the throne of Sweden seemed likely to become vacant in 1809, Frederick was interested in being elected there as well. Frederick actually was the first monarch of Denmark and Norway to descend from Gustav I of Sweden, who had secured Sweden's independence in 1520s after the period of the Kalmar Union with other Scandinavian countries. However, Frederick's brother-in-law, Prince Christian Augustus of Augustenborg, was first elected to the throne of Sweden, followed by the French Marshal Bernadotte. During the Napoleonic Wars, he tried to maintain neutrality; however, after the British bombardment of Copenhagen, he was forced to ally Denmark-Norway with Napoleon. After the French defeat in Russia in 1812, the Allies again asked him to change sides but he refused. Many Danish historians portray the king as stubborn, incompetent, and motivated by a misconceived loyalty towards Napoleon. However, some historians in recent years have provided a different interpretation that sheds a better light on the king. He stayed with Napoleon in order to protect the exposed situation of Norway, which was dependent on grain imports and had become the target of Swedish territorial ambitions. He expected the wars would end with a great international conference in which Napoleon would have a major voice, and would help protect Denmark's interests, especially in Norway. After the French defeat in the Napoleonic Wars in 1814 and the loss of the Norwegian crown, Frederick VI carried through an authoritarian and reactionary course, giving up the liberal ideas of his years as a prince regent. Censorship and suppression of all opposition together with the poor state of the country's economy made this period of his reign somewhat gloomy, though the king himself in general maintained his position of a well-meaning autocrat. From the 1830s the economic depression was eased a bit and from 1834 the king reluctantly accepted a small democratic innovation by the creation of the Assemblies of the Estate (purely consultative regional assemblies); this had the unintended result of later exacerbating relations between Danes and Germans in Schleswig, whose regional assembly became a forum for constant bickering between the two national groups.", "section_level": 1}, {"title": "Later life and succession.", "content": "Frederick VI was known as a patron of astronomy and in 1832 offered gold medal prizes to anyone who discovered a comet using a telescope.

Christian did all he could personally to strengthen the bonds between the Norwegians and the royal house of Denmark. Though his endeavours were opposed by the so-called Swedish party, which desired a dynastic union with Sweden, he placed himself at the head of the Norwegian party of independence after the Treaty of Kiel had forced the king to cede Norway to the king of Sweden. He was elected Regent of Norway by an assembly of notables on 16 February 1814. This election was confirmed by the Norwegian Constituent Assembly convoked at Eidsvoll on 10 April, and on 17 May the constitution was signed and Christian was unanimously elected king of Norway under the name Christian Frederick (Kristian Frederik in Norwegian). Christian next attempted to interest the great powers in Norway's cause, but without success. On being pressed by the commissioners of the allied powers to bring about a union between Norway and Sweden in accordance with the terms of the treaty of Kiel, and then return to Denmark, he replied that, as a constitutional king, he could do nothing without the consent of the parliament (Storting), which would not be convoked until there was a suspension of hostilities on the part of Sweden. Sweden refused Christian's conditions and a short military campaign ensued in which the Norwegian army was defeated by the forces of the Swedish crown prince Charles John. The brief war concluded with the Convention of Moss on 14 August 1814.

In his attitude to the growing national unrest in the twin duchies of Schleswig and Holstein he often seemed hesitant and half-hearted, which damaged his position there. It was not until 1846 that he clearly supported the idea of Schleswig being a Danish area. King Christian VIII continued his predecessor's patronage of astronomy, awarding gold medals for the discovery of comets by telescope and financially supporting Heinrich Christian Schumacher with his publication of the scientific journal \"Astronomische Nachrichten\". It was during his reign that the last remnants of Danish India, namely Tranquebar in the south and Serampore in Bengal, were sold to the British in 1845. His only legitimate son, the future Frederick VII (1808–1863) was married three times, but produced no legitimate issue.

However, in 1161, King Géza II of Hungary signed an agreement and recognised Alexander III as the rightful pope and declared that the supreme spiritual leader was the only one who could exercise the rite of investiture. This meant that Alexander's legitimacy was gaining strength, as soon proved by the fact that other monarchs, such as the king of France and King Henry II of England, recognized his authority. Because of imperial strength in Italy, Alexander was forced to reside outside Rome for a large part of his pontificate. When news reached him of the death of Victor in 1164, he openly wept, and scolded the cardinals in his company for rejoicing at the end of the rival antipope. However, the dispute between Alexander III, Victor IV and his successors Paschal III and Calixtus III (who had the German imperial support) continued until Frederick Barbarossa's defeat at the Legnano in 1176, after which Barbarossa finally (in the Peace of Venice of 1177) recognized Alexander III as pope.

The latter appointed a Benedictine monk Fulco as a bishop in Estonia. In 1171, Alexander became the first pope to address the situation of the Church in Finland, with Finns allegedly harassing priests and only relying on God in time of war. In the bull \"Non parum animus noster\", in 1171 or 1172, he gave papal sanction to ongoing crusades against pagans in northern Europe, promising remission of sin for those who fought there. In doing so, he legitimized the widespread use of forced conversion as a tactic by those fighting in the Baltic. In 1166, Alexander received an embassy from the Byzantine emperor Manuel I. The Byzantine ambassador, the \"sebastos\" Iordanos, relayed that Manuel would end the Great Schism of the eastern and western churches if Alexander would recognize him as emperor. As emperor, Manuel would supply the pope with men and money to restore his authority in Italy. Alexander gave an evasive answer, but in 1168 he rejected outright the same proposal from a second Byzantine embassy. His stated reason amounted to it being too difficult. He appears to have feared Byzantine domination of Italy if the pope owed his position to its support. Besides checkmating Barbarossa, Alexander humbled King Henry II of England for the murder of Thomas Becket in 1170, to whom he was unusually close, later canonizing Becket in 1173. This was the second English saint canonized by Alexander, the first being Edward the Confessor in 1161. Nonetheless, he confirmed the position of Henry as Lord of Ireland in 1172.

Also on the heels of the re-release of Tarde's works has come an important development in which French sociologist Bruno Latour has referred to Tarde as a possible predecessor to Actor-Network Theory in part because of Tarde's criticisms of Durkheim's conceptions of the Social.

Voisin's aircraft could seat only one person, so she operated the plane by herself while he stood on the ground and gave instructions. After she mastered taxiing around the airfield, she lifted off and flew. De Laroche's flight is often cited as the first by a woman in a powered heavier-than-air craft; there is evidence that two other women, P. Van Pottelsberghe and Thérèse Peltier, had flown the previous year with Henri Farman and Delagrange respectively as passengers but not as pilots. Decades later, aviation journalist Harry Harper wrote that until de Laroche made her celebrated flight on the Voisin, she had only flown once, for a short hop, as a passenger; when she first took the controls, Charles Voisin expressly forbade her to attempt a flight; and after taxiing twice across the airfield, she took off, flying \"ten or fifteen feet high\" and handling the controls with \"cool, quick precision\". Although Gabriel Voisin wrote, \"... my brother [was] entirely under her thumb\", the story of de Laroche as a headstrong woman making the flight after scant preparation and against Voisin's orders almost certainly romanticises what actually took place. \"Flight\" magazine, a week after the flight, reported: \"For some time the Baroness has been taking lessons from M. Chateau, the Voisin instructor, at Chalons, and on Friday of last week she was able to take the wheel for the first time. This initial voyage into the air was only a very short one, and \"terra firma\" was regained after.\" \"Flight\" was also responsible for bestowing the title \"Baroness\" upon de Laroche, as she was not of noble birth. \"Flight\" added that on the following day she circled the flying field twice, \"the turnings being made with consummate ease. During this flight of about four miles (6 km) there was a strong gusty wind blowing, but after the first two turnings the Baroness said that it did not bother her, as she had the machine completely under control.\" On 8 March 1910, de Laroche became the first woman in the world to receive a pilot licence when the Aero-Club of France issued her licence #36 of the \"Fédération Aéronautique Internationale\" (International Aeronautics Federation or F.A.I.).

He made his debut in the world cup in January 1989, finishing 11th on 15 km freestyle in Kavgolovo. In December the same year, he won his first world cup race. He finished first on the 15 km freestyle, the first world cup race of the season. In the FIS Nordic World Ski Championships 1991 in Val di Fiemme, Dæhlie won his first World Championship gold medal. He beat skiing legend Gunde Svan on the 15 km freestyle. The medal was unexpected, since Dæhlie was young and still unknown. It was Norway's first individual gold medal in the World Championships since Oddvar Brå won gold in the same race in Oslo in 1982. Dæhlie also skied the last leg on the winning 4 × 10 km relay team. In 1992, Dæhlie's period of dominance started. He won the world cup overall for the first time, a feat he would accomplish five more times in the next seven years. In Albertville Dæhlie won his first Olympic medals. He won gold in 10/15 km freestyle pursuit, 50 km freestyle and was on the winning team for the 4 × 10 km relay.

Dæhlie and Ulvang completed a clean sweep of the cross-country skiing gold medals, each winning three golds and a silver. Dæhlie was awarded Fearnley's Olympic Prize for his performance, a prize given to the best performing Norwegian athlete in the Olympics. In the 1994 Winter Olympics in Lillehammer, Norway, Dæhlie won gold in the 10 km classical style and the 15 km freestyle pursuit.

Philip went on to name one of his children Dæhlie Boit. Dæhlie was planning to compete in the 2002 Winter Olympics in Salt Lake City, but he was prevented from participating by a career-ending roller skiing accident in August 1999. The resulting back injury prevented Dæhlie from adding more medals to his collection. He retired from the sport in March 2001, having tried extensive rehabilitation and surgery to come back. His decision to retire shocked the nation of Norway, where Dæhlie was idolized for his great winning record. Dæhlie's eight Olympic titles are a record for the Winter Olympics, as are his total of 12 Olympic medals (he also won four silver medals) which he amassed in three Olympics (Albertville, Lillehammer and Nagano). In addition to his achievements at the Olympics he had great success in the World Championships where he won 17 medals of which nine were gold medals. He was particularly successful in the Trondheim 1997 World Championships, where he earned medals in all five events.

The abdomen is relatively soft, and may include remnants of the nymphal gills even in the adult. Both nymphs and adults have long, paired cerci projecting from the tip of their abdomens. The name \"Plecoptera\" literally means \"braided-wings\", from the Ancient Greek \"plekein\" (πλέκειν, \"to braid\") and \"pteryx\" (πτέρυξ, \"wing\"). This refers to the complex venation of their two pairs of wings, which are membranous and fold flat over their backs. Stoneflies are generally not strong fliers, and some species are entirely wingless. A few wingless species, such as the Lake Tahoe benthic stonefly (\"\"Capnia\" lacustra\") or \"Baikaloperla\", are the only known insects, perhaps with the exception of \"Halobates\", that are exclusively aquatic from birth to death. Some true water bugs (Nepomorpha) may also be fully aquatic for their entire lives, but can leave the water to travel. The nymphs (technically, \"naiads\") are aquatic and live in the benthic zone of well-oxygenated lakes and streams. A few species found in New Zealand and nearby islands have terrestrial nymphs, but even these inhabit only very moist environments. The nymphs physically resemble wingless adults, but often have external gills, which may be present on almost any part of the body. Nymphs can acquire oxygen via diffusing through the exoskeleton, or through gills located on behind the head, on the thorax, or around the anus. Due to their nymph's requirement for well oxygenated water, the species is very sensitive to water pollution. This makes them important indicators for water quality.

The Fujita scale was applied retroactively to tornadoes reported between 1950 and 1972 in the National Oceanic and Atmospheric Administration (NOAA) National Tornado Database. Fujita rated tornadoes from 1916–1992 and Tom Grazulis of The Tornado Project retroactively rated all known significant tornadoes (F2–F5 or causing a fatality) in the U.S. back to 1880. The Fujita scale was adopted in most areas outside of Great Britain. On February 1, 2007, the Fujita scale was decommissioned, and the Enhanced Fujita Scale was introduced in the United States. The new scale more accurately matches wind speeds to the severity of damage caused by the tornado. Though each damage level is associated with a wind speed, the Fujita scale is effectively a damage scale, and the wind speeds associated with the damage listed aren't rigorously verified. The Enhanced Fujita Scale was formulated due to research which suggested that the wind speeds required to inflict damage by intense tornadoes on the Fujita scale are greatly overestimated.

F0 was placed at a position specifying no damage (approximately the eighth level of the Beaufort scale), in analogy to how the Beaufort's zeroth level specifies little to no wind. From these wind speed numbers, qualitative descriptions of damage were made for each category of the Fujita scale, and then these descriptions were used to classify tornadoes. The diagram on the right illustrates the relationship between the Beaufort, Fujita, and Mach number scales. At the time Fujita derived the scale, little information was available on damage caused by wind, so the original scale presented little more than educated guesses at wind speed ranges for specific tiers of damage. Fujita intended that only F0–F5 be used in practice, as this covered all possible levels of damage to frame homes as well as the expected estimated bounds of wind speeds. He did, however, add a description for F6, which he phrased as \"inconceivable tornado\", to allow for wind speeds exceeding F5 and for possible future advancements in damage analysis which might show it. Furthermore, the original wind speed numbers have since been found to be higher than the actual wind speeds required to incur the damage described at each category. The error manifests itself to an increasing degree as the category increases, especially in the range of F3 through F5. NOAA notes that \"... precise wind speed numbers are actually guesses and have never been scientifically verified. Different wind speeds may cause similar-looking damage from place to place—even from building to building.

This research, as well as subsequent research, showed that tornado wind speeds required to inflict the described damage were actually much lower than the F-scale indicated, particularly for the upper categories. Also, although the scale gave general descriptions for the type of damage a tornado could cause, it gave little leeway for strength of construction and other factors that might cause a building to receive higher damage at lower wind speeds. Fujita tried to address these problems somewhat in 1992 with the Modified Fujita Scale, but by then he was semi-retired and the National Weather Service was not in a position for the undertaking of updating to an entirely new scale, so it went largely unenacted.

He could play so fast, that he was sometimes criticized for playing too many notes. As Return to Forever was disbanding around 1976, Di Meola began recording solo albums on which he demonstrated mastery of jazz fusion, flamenco, and Mediterranean music. His album \"Elegant Gypsy\" (1977) received a gold certification. In 1980 he recorded the acoustic live album \"Friday Night in San Francisco\" with Paco de Lucía and John McLaughlin. In the beginning of his career, as evidenced on his first solo album \"Land of the Midnight Sun\" (1976), Di Meola was noted for his technical mastery and extremely fast, complex guitar solos and compositions. But even on his early albums, he had begun to explore Mediterranean cultures and acoustic genres like flamenco. Notable examples are \"Mediterranean Sundance\" and \"Lady of Rome, Sister of Brazil\" from the \"Elegant Gypsy\" album (1977). His early albums were influential among rock and jazz guitarists. Di Meola continued to explore Latin music within jazz fusion on \"Casino\" and \"Splendido Hotel\". He exhibited a more subtle touch on acoustic numbers \"Fantasia Suite for Two Guitars\" from the \"Casino\" album and on the best-selling live album with McLaughlin and de Lucia, \"Friday Night in San Francisco\". The latter album became one of the most popular live albums for acoustic guitar, selling more than two million copies worldwide. With \"Scenario\", he explored the electronic side of jazz in a collaboration with Jan Hammer (keyboardist with Fusion pioneers \"Mahavishnu Orchestra,\" on albums with Jeff Beck, and later, composed the \"Miami Vice\" theme).

As the oldest son, he was expected to take over his father’s textile factory in Teesdorf; therefore, he attended a technical college for textile manufacture and a spinning and weaving college. In 1909 he converted to Roman Catholicism and married Franziska von Rothermann, the daughter of a knighted manufacturer. The following year, their son Hermann Friedrich Maria was born. His marriage ended in divorce in 1923. In 1927 he sold the textile factory and decided to study mathematics, philosophy and psychology at the University of Vienna. He embarked on a full-time literary career only around the age of 40. At the age of 45, his first major literary work, the trilogy \"The Sleepwalkers\", was published by Daniel Brody, for the Rhein Verlag in 1931/1932 in Munich. He was acquainted with many of the now well-known writers, intellectuals, and artists of his time, including Robert Musil, Rainer Maria Rilke, Elias Canetti, Leo Perutz, Franz Blei and writer and former nude model Ea von Allesch. With the annexation of Austria by the Nazis (1938), Broch was arrested in the small Alpine town of Bad Aussee for possession of a socialist magazine but was soon released. Shortly thereafter, a movement organized by friends – including James Joyce, Thornton Wilder, and his translators Edwin and Willa Muir – managed to help him emigrate; first to Britain and then to the United States, where he published his novel \"The Death of Virgil\" and his collection of short stories \"The Guiltless\". While in exile, he also continued to write on politics and work on mass psychology, similar to Elias Canetti and Hannah Arendt. His essay on mass behaviour remained unfinished. From the 15th of August to the 15th of September 1939, Hermann Broch lived at the Albert Einstein House at 112 Mercer Street Princeton, New Jersey when the Einsteins were on vacation. From 1942 to 1948 Broch lived in an attic apartment in Eric and Lili Kahler's house at One Evelyn Place in Princeton, New Jersey. Broch died in 1951 in New Haven, Connecticut.

Having begun the text as a short radio lecture in 1937, Broch expanded and redeveloped the text over the next eight years of his life, which witnessed a short incarceration in an Austrian prison after the Austrian Anschluss, his flight to Scotland via England, and his eventual exile in the United States. This extensive, difficult novel interweaves reality, hallucination, poetry and prose, and reenacts the last 18 hours of the Roman poet Virgil's life in the port of Brundisium (Brindisi). Here, shocked by the balefulness (\"Unheil\") of the society he glorifies in his \"Aeneid\", the feverish Virgil resolves to burn his epic, but is thwarted by his close friend and emperor Augustus before he succumbs to his fatal ailment. The final chapter exhibits the final hallucinations of the poet, where Virgil voyages to a distant land at which he witnesses roughly the biblical creation story in reverse. The French composer Jean Barraqué composed a number of works inspired by \"The Death of Virgil\". Erich Heller observed that if \"\"The Death of Virgil\" is his masterpiece... it is a very problematical one, for it attempts to give literary shape to the author's growing aversion to literature. In the very year the novel appeared, Broch confessed to 'a deep revulsion' from literature as such – 'the domain of vanity and mendacity'. Written with a paradoxical, lyrical exuberance, it is the imaginary record of the poet’s last day and his renunciation of poetry. He commands the manuscript of the \"Aeneid\" to be destroyed, not because it is incomplete or imperfect but because it is poetry and not 'knowledge'. He even says his \"Georgics\" are useless, inferior to any expert treatise on agriculture.

Hence, it is necessary to restrict attention to a more limited family of subsets. For the standard tools of probability theory, such as joint and conditional probabilities, to work, it is necessary to use a σ-algebra, that is, a family closed under complementation and countable unions of its members. The most natural choice of σ-algebra is the Borel measurable set derived from unions and intersections of intervals. However, the larger class of Lebesgue measurable sets proves more useful in practice. In the general measure-theoretic description of probability spaces, an event may be defined as an element of a selected σ-algebra of subsets of the sample space.

In the acute zone the eye is flattened and the facets larger. The flattening allows more ommatidia to receive light from a spot and therefore higher resolution. There are some exceptions from the types mentioned above. Some insects have a so-called single lens compound eye, a transitional type which is something between a superposition type of the multi-lens compound eye and the single lens eye found in animals with simple eyes. Then there is the mysid shrimp, \"Dioptromysis paucispinosa\". The shrimp has an eye of the refracting superposition type, in the rear behind this in each eye there is a single large facet that is three times in diameter the others in the eye and behind this is an enlarged crystalline cone. This projects an upright image on a specialized retina. The resulting eye is a mixture of a simple eye within a compound eye. Another version is the pseudofaceted eye, as seen in Scutigera. This type of eye consists of a cluster of numerous ocelli on each side of the head, organized in a way that resembles a true compound eye. The body of \"Ophiocoma wendtii\", a type of brittle star, was previously thought to be covered with ommatidia, turning its whole skin into a compound eye. Asymmetries in compound eyes may be associated with asymmetries in behaviour. For example, \"Temnothorax albipennis\" ant scouts show behavioural lateralization when exploring unknown nest sites, showing a population-level bias to prefer left turns.

As a result, the plural \"opera\" of \"opus\" tends to be avoided in English. In other languages such as German, however, it remains common.", "section_level": 1}, {"title": "Early usage.", "content": "In the arts, an opus number usually denotes a work of musical composition, a practice and usage established in the seventeenth century when composers identified their works with an opus number. In the eighteenth century, publishers usually assigned opus numbers when publishing groups of like compositions, usually in sets of three, six or twelve compositions. Consequently, opus numbers are not usually in chronological order, unpublished compositions usually had no opus number, and numeration gaps and sequential duplications occurred when publishers issued contemporaneous editions of a composer’s works, as in the sets of string quartets by Joseph Haydn (1732–1809) and Ludwig van Beethoven (1770–1827); Haydn's Op. 76, the Erdödy quartets (1796–97), comprises six discrete quartets consecutively numbered Op. 76 No. 1 – Op. 76 No. 6; whilst Beethoven's Op. 59, the Rasumovsky quartets (1805–06), comprises String Quartet No. 7, String Quartet No. 8, and String Quartet No. 9.", "section_level": 1}, {"title": "19th century to date.", "content": "From about 1800, composers usually assigned an opus number to a work or set of works upon publication. After approximately 1900, they tended to assign an opus number to a composition whether published or not. However, practices were not always perfectly consistent or logical. For example, early in his career, Beethoven selectively numbered his compositions (some published without opus numbers), yet in later years, he published early works with high opus numbers. Likewise, some posthumously published works were given high opus numbers by publishers, even though some of them were written early in Beethoven's career. Since his death in 1827, the un-numbered compositions have been cataloged and labeled with the German acronym WoO (\"Werk ohne Opuszahl\"), meaning \"work without opus number\"; the same has been done with other composers who used opus numbers. (There are also other catalogs of Beethoven's works – see Catalogues of Beethoven compositions.) The practice of enumerating a posthumous opus (\"Op. posth.\") is noteworthy in the case of Felix Mendelssohn (1809–47); after his death, the heirs published many compositions with opus numbers that Mendelssohn did not assign. In life, he published two symphonies (Symphony No. 1 in C minor, Op. 11; and Symphony No. 3 in A minor, Op. 56), furthermore he published his symphony-cantata \"Lobgesang\", Op. 52, which was posthumously counted as his Symphony No. 2; yet, he chronologically wrote symphonies between symphonies Nos. 1 and 2, which he withdrew for personal and compositional reasons; nevertheless, the Mendelssohn heirs published (and cataloged) them as the \" Italian\" Symphony No. 4 in A major, Op. 90, and as the \" Reformation\" Symphony No. 5 in D major and D minor, Op. 107. While many of the works of Antonín Dvořák (1841–1904) were given opus numbers, these did not always bear a logical relationship to the order in which the works were written or published. To achieve better sales, some publishers, such as N. Simrock, preferred to present less experienced composers as being well established, by giving some relatively early works much higher opus numbers than their chronological order would merit. In other cases, Dvořák gave lower opus numbers to new works to be able to sell them to other publishers outside his contract obligations. This way it could happen that the same opus number was given to more than one of his works. Opus number 12, for example, was assigned, successively, to five different works (an opera, a concert overture, a string quartet, and two unrelated piano works). In other cases, the same work was given as many as three different opus numbers by different publishers. The sequential numbering of his symphonies has also been confused: (a) they were initially numbered by order of publication, not composition; (b) the first four symphonies to be composed were published after the last five; and (c) the last five symphonies were not published in order of composition. The \"New World Symphony\" originally was published as No. 5, later was known as No. 8, and definitively was renumbered as No. 9 in the critical editions published in the 1950s. Other examples of composers' historically inconsistent opus-number usages include the cases of César Franck (1822–1890), Béla Bartók (1881–1945), and Alban Berg (1885-1935), who initially numbered, but then stopped numbering their compositions. Carl Nielsen (1865–1931) and Paul Hindemith (1895–1963) were also inconsistent in their approaches. Sergei Prokofiev (1891–1953) was consistent and assigned an opus number to a composition \"before\" composing it; at his death, he left fragmentary and planned, but numbered, works. In revising a composition, Prokofiev occasionally assigned a new opus number to the revision; thus Symphony No. 4 is two thematically related but discrete works: Symphony No. 4, Op. 47, written in 1929; and Symphony No. 4, Op. 112, a large-scale revision written in 1947. Likewise, depending upon the edition, the original version of Piano Sonata No. 5 in C major, is cataloged both as Op. 38 and as Op. 135. Despite being used in more or less normal fashion by a number of important early-twentieth-century composers, including Arnold Schoenberg (1874-1951) and Anton Webern (1883-1945), opus numbers became less common in the later part of the twentieth century.", "section_level": 1}, {"title": "Other catalogues.", "content": "To manage inconsistent opus-number usages — especially by composers of the Baroque (1600–1750) and of the Classical (1720—1830) music eras — musicologists have developed comprehensive and unambiguous catalogue number-systems for the works of composers such as:", "section_level": 1}], "src_summary": "In musical composition, the opus number is the \"work number\" that is assigned to a musical composition, or to a set of compositions, to indicate the chronological order of the composer's production.

Nevertheless, this section outlines some rules and traditions which are commonly upheld. In contrast to baseball and cricket, there is no pitcher/bowler, but the batsman himself throws or bounces the ball (usually a tennis ball) and hits it with his bat. A selection of bats is sometimes available, with a regular wooden or metallic baseball bat usually present, and a paddle-like bat resembling a cricket bat available for less experienced batsmen. On some occasions, there is also a stiff racket. The valid area for a successful batting is usually delimited by natural features such as trees, or simply an agreed upon imaginary border, this rule only restricts how widely the batter can hit, but not how far. The proportions of the field and positioning of the players are arbitrary, albeit usually adjusted according to the batting and running ability of the players, as well as team size. When the batsman successfully hits the ball, they drop the bat and make their way around the four bases (usually counter-clockwise), while the players in the catching team catch and throw the ball back to the designated catcher positioned by the outing base (\"brännplatta\"), who announces the end of the batting round with \"out\" (\"bränd\", \"burned\") when the catcher has made contact with the outing base whilst holding the ball. If a player from the batting team is caught between two bases at the end of the batting round, they move back to either the last visited base or first base (depending on the local rules) and the catching team scores a point. If a batsman is unsuccessful at batting after the three attempts allowed, they move to the first base and will run when the next batsman bats a valid hit. There are no restrictions on the number of players at each base. If all players on the batting team fail to reach the fourth base (and thus rejoin the queue) and no batsmen remain in the queue, the inner team is caught out (\"utebrända\"), and depending on local rules extra points may be awarded to the opposing team in return for the safe passage on the players to the queue.

Since 1974 an annual Students World Championship tournament has been held in the northern city of Umeå, whereby some standardized rules are followed. The world championship is called Brännbollscupen, which is followed by the festival Brännbollsyran. Brännboll is enjoyed by elementary schoolchildren in the American Upper Midwest (particularly Minnesota), due to the area's large Scandinavian influence. A similar game, brennball, is popular in PE classes at German schools. It is usually played indoors, with a larger ball (such as a volleyball or a basketball) and without a bat; batting is replaced by throwing. The bases are usually far larger than in baseball and more than one player can be on the same base at the same time. German brennball is rarely played outside a PE setting. In Norway another similar game, called (deadball or deathball), is common. The game has six or five rings (approximately one meter in diameter) marked on the ground instead of four bases, limiting the number of players secured by a given ring to the amount that can fit within it. The term \"dead\" (død) is used instead of \"burnt\" or \"out\". When the catcher gets the ball he or she also has to bounce it on the ground (usually on a predetermined square called døboksen, \"the death box\") and shout \"dø\" (\"die\"). A dead player is exempt from play for the rest of the round unless a home run is achieved; in which case a set number of dead players (usually either one or all of them, depending on the rule-set) are \"saved\" and allowed to rejoin the queue. To complete a run a player has to reenter the \"in\" side of the field rather than just reaching the last base. Scoring- and win-conditions varies widely from rule-set to rule-set. Points can be determined by runs, just by home runs, by rounds won (usually determined by reaching set numbers of home runs for the in-team or dead players for the out-team) or by combinations of the above. Sometimes points are not used at all and a game ends with no formal winner after a set amount of time. Another version of the game, popular among students, is called ölbrännboll (beer-brännball), where beercases are used as bases so the players of the batting team, waiting to run can drink freely.

The swept-forward wing was suggested by the project's head designer, Dr. Hans Wocke as a way of providing extra lift at low airspeeds - necessary because of the poor responsiveness of early turbojets at the vulnerable times of takeoff and landing. A further structural advantage of the forward-swept wing was that it would allow for a single massive weapons bay in the best location, the centre of gravity of the plane, with the main wing spar passing behind the bomb bay. The same structural requirement meant the wing could then be located at the best aerodynamic location, the centre of the fuselage. Prior to the assembly of the first Ju 287, an He 177 A-5 (designated as na He 177 prototype, V38) was modified at the Letov plant in Prague to examine the technical characteristics of this single large bomb bay design. The first and second prototypes (Ju 287 V1 and V2; both designated Ju 288 V201 and Ju 288 V202 for security reasons) were intended to evaluate the concept, with V1 being intended to test the FSW and V2 being earmarked for evaluating flight at high subsonic speeds, and both were assembled from the fuselages of the He 177 A-5, the tail of the Ju 188G-2, main undercarriage from a Ju 352, and nosewheels taken from shot-down B-24 Liberators, all of which were fixed to lower weight and complexity, and equipped with spats to reduce drag. The fixed undercarriage was used as the wing box couldn't have cutouts for wheel stowage which would reduce wing torsion box stiffness required for the forward sweep design. Later prototypes with higher power engines and higher top speed would have the undercarriage stowage in the centre fuselage sides Two of the Jumo 004 engines were hung in nacelles (pods) under the wings, with the other two mounted in nacelles added to the sides of the forward fuselage. Flight tests began on 16 August 1944 (pilot: Siegfried Holzbaur), with the aircraft displaying extremely good handling characteristics, as well as revealing some of the problems of the forward-swept wing under some flight conditions. The most notable of these drawbacks was 'wing warping', or excessive in flight flexing of the main spar and wing assembly. Tests suggested that the warping problem would be eliminated by concentrating greater engine mass under the wings. This technical improvement would be incorporated in the subsequent prototypes with under wing engines moved forward under leading edge as a mass balance. The Ju 287 was intended to be powered by four Heinkel-Hirth HeS 011 engines, but because of the development problems experienced with that engine, the BMW 003 was selected in its place. The second prototype (Junkers Ju 287 V2) would have had six engines (originally four underwing BMW 003s and two fuselage-mounted Jumo 004s, but later changed to two triple clusters composed of four Jumo 004s and two BMW 003s), and also differed from the Ju 287 V1 in having the main undercarriage struts with an inward cant, the horizontal stabilizer lowered by 30 centimeters, and light grey-colored trouser pants for the nose wheels. The third prototype, the Junkers Ju 287 V3, employed six BMW 003s, in a triple cluster under each wing, and featured the all-new fuselage and tail design intended for the production bomber, the Ju 287A-1, utilizing a pressurised cockpit used on the Junkers Ju 288. The Ju 287 V4 and V5 would have served as prototypes of the Ju 287A-2 and Ju 287B-1 respectively, and the V5 and V6 were to feature tail armament and ejection seats. The Ju 287B-1 would have had four thrust HeS 011 turbojets, while the Junkers Ju 287B-2 was to employ two thrust BMW 018 turbojets. While the Heinkel turbojet was in the pre-production phase at war's end, work on BMW's radical and very powerful turbine engine never proceeded past three barely-tested prototypes. The final Ju 287 variant design to be mooted was a Mistel combination-plane ground attack version, comprising an unmanned explosives-packed \"drone\" 287 and a manned Me 262 fighter attached to the top of the bomber by a strut assembly. The cockpit of the 287 would be replaced by a massive impact-fused warhead. Takeoff and flight control of the combination would be under the direction of the 262's pilot. The 262 would disengage from the 287 drone as the Mistel neared its target, the pilot of the fighter remotely steering the 287 for the terminal phase of its strike mission. Work on the Ju 287 programme, along with all other pending German bomber projects (including Junkers' other ongoing heavy bomber design, the piston-engined Ju 488) came to a halt in July 1944, but Junkers was allowed to go forward with the flight testing regime on the V1 prototype. The components for the Junkers Ju 287 V2 had been completed by that time, and were shipped to Brandis for final assembly. Seventeen test flights were undertaken in total, which passed without notable incident. Minor problems, however, did arise with the turbojet engines and the equally-experimental HWK 109-501 higher-thrust (14.71 kN apiece) bipropellant \"Starthilfe\" RATO booster units, which proved to be unreliable over sustained periods. This initial test phase was designed purely to assess the low-speed handling qualities of the forward-swept wing, but despite this the V1 was dived at full jet power on at least one occasion, attaining a speed in the medium dive-angle employed of 660 km/h. To gain data on airflow patterns, small woolen tufts were glued to the airframe and the \"behavior\" of these tufts during flight was captured by a cine camera mounted on a sturdy tripod directly ahead of the plane's tailfin. After the seventeenth and last flight in late autumn of 1944, the V1 was transferred to the Luftwaffe's primary \"Erprobungsstelle\" evaluation and test centre at Rechlin\", for flow tests. However, in March 1945, for unknown reasons, the Ju 287 program was restarted, with the RLM issuing a requirement for mass production of the jet bomber (100 airframes a month) as soon as possible.", "section_level": 1}, {"title": "Postwar development.", "content": "The Junkers factory in Dessau was overrun by the Red Army in late April 1945.

Wocke and his staff were captured by the Red Army and taken to the Soviet Union, and remnants of V2, especially the wings, were used in construction of the EF 131 which was flown on 23 May 1947, but by that time, jet development had already overtaken the Ju 287.

Although he wrote \"Werther\" at the age of 24, it was all for which some of his visitors in his old age knew him. His views of literature had changed radically by then. He even denounced the Romantic movement as \"everything that is sick.\" Goethe described the powerful impact the book had on him, writing that even if Werther had been a brother of his whom he had killed, he could not have been more haunted by his vengeful ghost. Yet, Goethe substantially reworked the book for the 1787 edition and acknowledged the great personal and emotional influence that \"The Sorrows of Young Werther\" could exert on forlorn young lovers who discovered it. As he commented to his secretary in 1821, \"It must be bad, if not everybody was to have a time in his life, when he felt as though \"Werther\" had been written exclusively for him.\" Even fifty years after the book's publication, Goethe wrote in a conversation with Johann Peter Eckermann about the emotional turmoil he had gone through while writing the book: \"That was a creation which I, like the pelican, fed with the blood of my own heart.\"", "section_level": 1}, {"title": "Cultural impact.", "content": "\"The Sorrows of Young Werther\" turned Goethe, previously an unknown author, into a literary celebrity almost overnight. Napoleon Bonaparte considered it one of the great works of European literature, having written a Goethe-inspired soliloquy in his youth and carried \"Werther\" with him on his campaigning to Egypt. It also started the phenomenon known as the \"Werther Fever\", which caused young men throughout Europe to dress in the clothing style described for Werther in the novel. Items of merchandising such as prints, decorated Meissen porcelain and even a perfume were produced. The book reputedly also led to some of the first known examples of copycat suicide. The men were often dressed in the same clothing \"as Goethe's description of Werther and using similar pistols.\" Often the book was found at the scene of the suicide. Rüdiger Safranski, a modern biographer of Goethe, dismisses the Werther Effect 'as only a persistent rumor'. Nonetheless, this aspect of \"Werther Fever\" was watched with concern by the authorities – both the novel and the Werther clothing style were banned in Leipzig in 1775; the novel was also banned in Denmark and Italy.

The earliest electronic document management (EDM) systems managed either proprietary file types, or a limited number of file formats. Many of these systems later became known as document imaging systems, because they focused on the capture, storage, indexing and retrieval of image file formats. EDM systems evolved to a point where systems could manage any type of file format that could be stored on the network. The applications grew to encompass electronic documents, collaboration tools, security, workflow, and auditing capabilities. These systems enabled an organization to capture faxes and forms, to save copies of the documents as images, and to store the image files in the repository for security and quick retrieval (retrieval made possible because the system handled the extraction of the text from the document in the process of capture, and the text-indexer function provided text-retrieval capabilities). While many EDM systems store documents in their native file format (Microsoft Word or Excel, PDF), some web-based document management systems are beginning to store content in the form of html.

During puberty, estrogen causes the hymen to become very elastic and fimbriated.The hymen can stretch or tear as a result of various behaviors, by tampon or menstrual cup use, pelvic examinations with a speculum, regular physical activity, sexual intercourse, insertion of multiple fingers or items into the vagina, and activities such as gymnastics (doing 'the splits'), or horseback riding. Remnants of the hymen are called carunculae myrtiformes. A glass or plastic rod of 6 mm diameter having a globe on one end with varying diameter from 10 to 25 mm, called a Glaister Keen rod, is used for close examination of the hymen or the degree of its rupture. In forensic medicine, it is recommended by health authorities that a physician who must swab near this area of a prepubescent girl avoid the hymen and swab the outer vulval vestibule instead. In cases of suspected rape or child sexual abuse, a detailed examination of the hymen may be performed, but the condition of the hymen alone is often inconclusive.", "section_level": 1}, {"title": "Anatomic variations.", "content": "Normal variations of the hymen range from thin and stretchy to thick and somewhat rigid; or it may also be completely absent. An imperforate hymen occurs in 1-2 out of 1,000 infants. The only variation that may require medical intervention is the imperforate hymen, which either completely prevents the passage of menstrual fluid or slows it significantly. In either case, surgical intervention may be needed to allow menstrual fluid to pass or intercourse to take place at all. Prepubescent girls' hymenal openings come in many shapes, depending on hormonal and activity level, the most common being crescentic (posterior rim): no tissue at the 12 o'clock position; crescent-shaped band of tissue from 1–2 to 10–11 o'clock, at its widest around 6 o'clock. From puberty onwards, depending on estrogen and activity levels, the hymenal tissue may be thicker, and the opening is often fimbriated or erratically shaped. In younger children, a torn hymen will typically heal very quickly. In adolescents, the hymenal opening can naturally extend and variation in shape and appearance increases.

In one cross-cultural study, slightly more than half of all women self-reported bleeding during first intercourse, with significantly different levels of pain and bleeding reported depending on their region of origin. Not all women experience pain, and one study found a correlation between the experience of strong emotions - such as excitement, nervousness, or fear - with experiencing pain during first intercourse. In several studies of adolescent female rape victims, where patients were examined at a hospital following sexual assault, half or fewer of virgin victims had any injury to the hymen. Tears of the hymen occurred in less than a quarter of cases. However, virgins were significantly more likely to have injuries to the hymen than non-virgins. In a study of adolescents who had previously had consensual sex, approximately half showed evidence of trauma to the hymen. Trauma to the hymen may also occur in adult non-virgins following consensual sex, although it is rare. Trauma to the hymen may heal without any visible sign of injury. An observational study of adolescent sexual assault victims found that majority of wounds to the hymen healed without any visible sign of injury having occurred.

In the first of these essays Hoffmann traced the beginnings of musical Romanticism to the later works of Haydn and Mozart. It was Hoffmann's fusion of ideas already associated with the term \"Romantic\", used in opposition to the restraint and formality of Classical models, that elevated music, and especially instrumental music, to a position of pre-eminence in Romanticism as the art most suited to the expression of emotions.

Gilbert's syndrome is characterized by a 70–80% reduction in the glucuronidation activity of the enzyme (UGT1A1). The \"UGT1A1\" gene is located on human chromosome 2. More than 100 variants of the \"UGT1A1\" gene are known, designated as \"UGT1A1*n\" (where n is the general chronological order of discovery), either of the gene itself or of its promoter region. \"UGT1A1 \"is associated with a TATA box promoter region; this region most commonly contains the genetic sequence A(TA)TAA; this variant accounts for about 50% of alleles in many populations. However, several allelic polymorphic variants of this region occur, the most common of which results from adding another dinucleotide repeat TA to the promoter region, resulting in A(TA)TAA, which is called \"UGT1A1*28\"; this common variant accounts for about 40% of alleles in some populations, but is seen less often, around 3% of alleles, in Southeast and East Asian people and Pacific Islanders. In most populations, Gilbert's syndrome is most commonly associated with homozygous A(TA)TAA alleles. In 94% of GS cases, two other glucuronosyltransferase enzymes, UGT1A6 (rendered 50% inactive) and UGT1A7 (rendered 83% ineffective), are also affected. However, Gilbert's syndrome can arise without TATA box promoter polymorphic mutations; in some populations, particularly healthy Southeast and East Asians, Gilbert's syndrome is more often a consequence of heterozygote missense mutations (such as Gly71Arg also known as \"UGT1A1*6\", Tyr486Asp also known as \"UGT1A1*7\", Pro364Leu also known as \"UGT1A1*73\") in the actual gene coding region, which may be associated with significantly higher bilirubin levels.

GS patients have a ratio of unconjugated/conjugated (indirect/direct) bilirubin commensurately higher than those without GS. The level of total bilirubin is often further increased if the blood sample is taken after fasting for two days, and a fast can, therefore, be useful diagnostically.

As a young boy, Michael and his mother had been exiled to Beloozero in 1600. This was a result of the recently elected Tsar Boris Godunov, in 1598, falsely accusing his father, Feodor, of treason. This may have been partly because Feodor had married Ksenia Shestova against Boris' wishes. Michael was unanimously elected Tsar of Russia by a national assembly on 21 February 1613, but the delegates of the council did not discover the young Tsar and his mother at the Ipatiev Monastery near Kostroma until 24 March. He had been chosen after several other options had been removed, including royalty of Poland and Sweden. Initially, Martha protested, believing and stating that her son was too young and tender for so difficult an office, and in such a troublesome time. Michael's election and accession to the throne form the basis of the Ivan Susanin legend, which Russian composer Mikhail Glinka dramatized in his opera \"A Life for the Tsar\". In so dilapidated a condition was the capital at this time that Michael had to wait for several weeks at the Troitsa monastery, off, before decent accommodation could be provided for him at Moscow. He was crowned on 22 July 1613. The first task of the new tsar was to clear the land of the countries occupying it. Sweden and Poland were then dealt with respectively by the peace of Stolbovo (17 February 1617) and the Truce of Deulino (1 December 1618). The most important result of the Truce of Deulino was the return from exile of the tsar's father, who henceforth took over the government till his death in October 1633, Michael occupying quite a subordinate position. Michael's reign saw the greatest territorial expansion in Russian history. During his reign, the conquest of Siberia continued, largely accomplished by the Cossacks and financed by the Stroganov merchant family.

The first head of the Posolsky Prikaz under Michael was Pyotr Tretyakov until his death in 1618; he conducted policy of allying with Sweden against Poland. The next one, Ivan Gramotin had a reputation of a Poloniphile; this appointment was necessary to bring forth Filaret's release from captivity. In the mid-1620s Filaret began preparations for war with Poland; Gramotin fell in his disfavour and was fired and exiled in 1626. The same fate was shared by Efim Telepnev in 1630 and Fedor Likhachov in 1631 – they too tried to soothe Filaret's belligerent approach. Ivan Gryazev, appointed in 1632, was promoted from second ranks of bureaucracy to fulfill Filaret's orders.

Charles also helped Louis De Geer to carry through his reform of the Parliament of Sweden in 1866. He also declared the freedom of women by passing the law of legal majority for unmarried women in 1858 – his sister Princess Eugenie became the first woman who was declared mature. Charles, like his father Oscar I, was an advocate of Scandinavianism and the political solidarity of the three northern kingdoms, and his friendship with Frederick VII of Denmark, it is said, led him to give half promises of help to Denmark on the eve of the war of 1864, which, in the circumstances, were perhaps misleading and unjustifiable. In view, however, of the unpreparedness of the Swedish army and the difficulties of the situation, Charles was forced to observe a strict neutrality. He died in Malmö on 18 September 1872. Charles XV attained some eminence as a painter and as a poet. He was followed on the thrones of both Norway and Sweden by his brother Oscar II.

While the monarchy had been \"de facto\" subordinate to the Riksdag and ministers since the definitive establishment of parliamentary rule in 1917, the king still nominally retained considerable reserve powers.

A church at \"Caofstein\" was first mentioned in a 788 deed issued by Bishop Arno of Salzburg. At that time, the Lower Inn Valley was part of the Bavarian realm under the Agilolfing duke Tassilo III, who was deposed by Charlemagne and replaced by Prefect Gerold. The Fortress is first documented in 1205 as a possession of the Bishop of Regensburg and the Duke of Bavaria. In the early 14th century, the Wittelsbach emperor Louis IV, also Bavarian duke, vested the Kufstein citizens with rights of jurisdiction. Kufstein passed to the County of Tyrol in 1342, when it was a wedding gift to Countess Margaret from her husband, Emperor Louis's son Louis the Brandenburger. However, it fell back to Bavaria upon Margaret's death in 1369. Duke Stephen III of Bavaria granted Kufstein city status in 1393, due to its prominence as a trading and docking point on the Inn River. From 1415 onwards, his son and successor Duke Louis VII had the Fortress largely rebuilt and expanded. The possession of the strategically important Kufstein border fortress remained disputed. In 1504, the Habsburg emperor Maximilian I took the opportunity of the War of the Succession of Landshut within the Bavarian Wittelsbach dynasty: his Austrian forces laid siege to the town, and at the Imperial Diet in Cologne the next year, the emperor resolved upon the cession of the Kufstein territories to the Habsburg lands of Tyrol. Maximilian had the prominent \"Kaiserturm\" tower of the fortress erected, which was finished in 1522. During the War of the Spanish Succession, the castle was again besieged by Bavarian troops under Elector Maximilian II Emanuel in 1703, nevertheless the Austrian domains were confirmed by the Treaty of Ilbersheim the next year. After the War of the Third Coalition, Kufstein once again was awarded to the newly established Kingdom of Bavaria in the 1805 Peace of Pressburg and the Tyrolean Rebellion of 1809 was crushed by the Bavarian Army. Finally in 1813/14 it passed to the Austrian Empire. In the 19th century, Kufstein Fortress was turned into a bastille for political prisoners, such as the Hungarian outlaw Sándor Rózsa, who spent several years here before he was finally pardoned in 1868.

A difference of opinion developed in the community concerning the interpretation of the rule regarding property. The Observants held to a strict interpretation that the friars may not hold any property either individually nor communally. The literal and unconditional observance of this was rendered impracticable by the great expansion of the order, its pursuit of learning, and the accumulated property of the large cloisters in the towns. Regulations were drafted by which all alms donated were held by custodians appointed by the Holy See, who would make distributions upon request. It was John XXII who had introduced Conventualism in the sense of community of goods, income, and property as in other religious orders, in contradiction to Observantism or the strict observance of the rule. Pope Martin V, in the Brief \"Ad statum\" of 23 August 1430, allowed the Conventuals to hold property like all other orders. Projects for a union between the two main branches of the order were put forth not only by the Council of Constance but by several popes, without any positive result. By direction of Pope Martin V, John of Capistrano drew up statutes which were to serve as a basis for reunion, and they were actually accepted by a general chapter at Assisi in 1430; but the majority of the Conventual houses refused to agree to them, and they remained without effect. Equally unsuccessful were the attempts of the Franciscan Pope Sixtus IV, who bestowed a vast number of privileges on both original mendicant orders, but by this very fact lost the favor of the Observants and failed in his plans for reunion. Julius II succeeded in doing away with some of the smaller branches, but left the division of the two great parties untouched.

Leo X summoned on 11 July 1516 a general chapter to meet at Rome on the feast of Pentecost 31 May 1517.

Jordan enrolled in the Technical University of Hannover in 1921 where he studied zoology, mathematics, and physics. As was typical for a German university student of the time, he shifted his studies to another university before obtaining a degree. The University of Göttingen, his destination in 1923, was then at the very zenith of its powers in mathematics and the physical sciences, such as under the guidance of mathematician David Hilbert and the physicist Arnold Sommerfeld.

Today, von Neumann algebras are also employed for this purpose. Jordan algebras have since been applied in projective geometry, number theory, complex analysis, optimization, and many other fields of pure and applied mathematics, and continue to be used in studying the mathematical and conceptual underpinnings of quantum theory. In 1966, Jordan published his 182-page work \"Die Expansion der Erde. Folgerungen aus der Diracschen Gravitationshypothese\" (The expansion of the Earth. Conclusions from the Dirac gravitation hypothesis) in which he developed his theory that, according to Paul Dirac's hypothesis of a steady weakening of gravitation throughout the history of the universe, the Earth may have swollen to its current size, from an initial ball of a diameter of only about. This theory could explain why the ductile lower sima layer of the Earth's crust is of a comparatively uniform thickness, while the brittle upper sial layer of the Earth's crust had broken apart into the main continental plates. The continents having to adapt to the ever flatter surface of the growing ball, the mountain ranges on the Earth's surface would, in the course of that, have come into being as constricted folds.

While many of his colleagues believed the Treaty to be unjust, Jordan went much further and became increasingly nationalistic and right-wing. He wrote numerous articles in the late 1920s that propounded an aggressive and bellicose stance. He was an anti-communist and was particularly concerned about the Russian Revolution and the rise of the Bolsheviks. In 1933, Jordan joined the Nazi party, like Philipp Lenard and Johannes Stark, and, moreover, joined an SA unit. He supported the Nazis' nationalism and anti-communism but at the same time, he remained \"a defender of Einstein\" and other Jewish scientists. Jordan seemed to hope that he could influence the new regime; one of his projects was attempting to convince the Nazis that modern physics developed as represented by Einstein and especially the new Copenhagen brand of quantum theory could be the antidote to the \"materialism of the Bolsheviks\". However, while the Nazis appreciated his support for them, his continued support for Jewish scientists and their theories led him to be regarded as politically unreliable. Jordan enlisted in the Luftwaffe in 1939 and worked as a weather analyst at the Peenemünde rocket center, for a while. During the war he attempted to interest the Nazi party in various schemes for advanced weapons. His suggestions were ignored because he was considered \"politically unreliable\", probably because of his past associations with Jews (in particular: Courant, Born, and Wolfgang Pauli) and the so-called \"Jewish physics\". Had Jordan not joined the Nazi party, it is conceivable that he could have won a Nobel Prize in Physics for his work with Max Born. Born would go on to win the 1954 Physics Prize with Walther Bothe. Wolfgang Pauli declared Jordan to be \"rehabilitated\" to the West German authorities some time after the war, allowing him to regain academic employment after a two-year period. He then recovered his full status as a tenured professor in 1953. Jordan went against Pauli's advice, and reentered politics after the period of denazification came to an end under the pressures of the Cold War. He secured election to the Bundestag standing with the conservative Christian Democratic Union.

The Theater of Hamburg engaged him for some years for a position today known as \"dramaturge\". He was first of this kind and described his task as ‘\"dramatic judge\" (\"dramatischer Richter\") who has to be able to tell the difference between the stake the play has or the main actor or the director to make us feel comfortable or not while watching a theatrical performance. From 1767–1770 Lessing wrote and published as result a series of criticisms titled \"Hamburg Dramaturgy (Hamburgische Dramaturgie).\" These works analyzed, criticized and theorized the German theatre, and made Lessing the father of modern dramaturgy. Based on Lessing's \"Hamburgische Dramaturgie\" (Lessing and Berghahn, 1981) and \"Laokoon\" and Hegel’s \"Aesthetics\" (written 1835–1838), many authors, including Hölderlin, Goethe, Schelling, Thornton Wilder, Arthur Miller, and Tennessee Williams, started to reflect on theater, not only in Germany., Gustav Freytag summed up those reflections in his book \"The Technique of the Drama\", which has been translated into English and published in the late 19th century in the USA. Freytag's book is seen as the blueprint for the first Hollywood screenwriting manuals. \"The Technique of Play Writing\" by Charlton Andrews, 1915, refers to European and German traditions of dramaturgy and understanding dramatic composition. Another important work in the Western theatrical tradition is \"Poetics\" by Aristotle (written around 335 BCE). In this work Aristotle analyzes tragedy. Aristotle considers \"Oedipus Rex\" (c. 429 BCE) as the quintessential dramatic work. He analyzes the relations among character, action, and speech, gives examples of good plots, and examines the reactions the plays provoke in the audience. Many of his \"rules\" are referred to today as \"Aristotelian drama\". In \"Poetics\", Aristotle discusses many key concepts of drama, such as anagnorisis and catharsis. \"Poetics\" is the earliest surviving Western work of dramatic theory.

Institutional dramaturges may participate in many phases of play production including casting of the play, offering in-house criticism of productions-in-progress, and informing the director, the cast, and the audience about a play’s history and its current importance. In America, this type of dramaturgy is sometimes known as Production Dramaturgy. Institutional or production dramaturges may make files of materials about a play's history or social context, prepare program notes, lead post-production discussions, or write study guides for schools and groups.

She asked that the court declare her a co-author of \"Rent\" and grant her 16 per cent of the author's share of the royalties. Although she made her claim only after the show became a Broadway hit, the case is not without precedent. For instance, 15 per cent of the royalties of \"Angels in America\" go to playwright Tony Kushner's dramaturge. On June 19, 1998, the United States Court of Appeals for the Second Circuit affirmed the original court's ruling that Thomson was not entitled to be credited with co-authorship of \"Rent\" and that she was not entitled to royalties.

Although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced more than 100 centuries ago in what is now China, according to an interpretation of ancient paintings. However, this continues to be debated. The word \"ski\" is one of a handful of words that Norway has exported to the international community. It comes from the Old Norse word \"skíð\" which means \"split piece of wood or firewood\". Asymmetrical skis were used in northern Finland and Sweden until at least the late 19th century. On one foot, the skier wore a long straight non-arching ski for sliding, and a shorter ski was worn on the other foot for kicking. The underside of the short ski was either plain or covered with animal skin to aid this use, while the long ski supporting the weight of the skier was treated with animal fat in a similar manner to modern ski waxing. Early skiers used one long pole or spear. The first depiction of a skier with two ski poles dates to 1741. Troops on continental Europe were equipped with skis by 1747. Skiing was primarily used for transport until the mid-19th century, but since then has also become a recreation and sport. Military ski races were held in Norway during the 18th century, and ski warfare was studied in the late 18th century. As equipment evolved and ski lifts were developed during the late 19th and early 20th centuries, two main genres of skiing emerged—Alpine (downhill) skiing and Nordic skiing.

Hugh was influenced by many people, but chiefly by Saint Augustine, especially in holding that the arts and philosophy can serve theology. Hugh's most significant works include: Other works by Hugh of St Victor include: Various other works were wrongly attributed to Hugh in later thought. One such particularly influential work was the \"Exposition of the Rule of St Augustine\", now accepted to be from the Victorine school but not by Hugh of St Victor. A new edition of Hugh's works has been started. The first publication is: \"Hugonis de Sancto Victore De sacramentis Christiane fidei\", ed. Rainer Berndt, Münster: Aschendorff, 2008.", "section_level": 1}, {"title": "Philosophy and theology.", "content": "The early \"Didascalicon\" was an elementary, encyclopedic approach to God and Christ, in which Hugh avoided controversial subjects and focused on what he took to be commonplaces of Catholic Christianity. In it he outlined three types of philosophy or \"science\" [scientia] that can help mortals improve themselves and advance toward God: theoretical philosophy (theology, mathematics, physics) provides them with truth, practical philosophy (ethics, economics, politics) aids them in becoming virtuous and prudent, and \"mechanical\" or \"illiberal\" philosophy (e.g., carpentry, agriculture, medicine) yields physical benefits. A fourth philosophy, logic, is preparatory to the others and exists to ensure clear and proper conclusions in them. Hugh's deeply mystical bent did not prevent him from seeing philosophy as a useful tool for understanding the divine, or from using it to argue on behalf of faith. Hugh was heavily influenced by Augustine's exegesis of Genesis. Divine Wisdom was the archetypal form of creation. The creation of the world in six days was a mystery for man to contemplate, perhaps even a sacrament. God's forming order from chaos to make the world was a message to humans to rise up from their own chaos of ignorance and become creatures of Wisdom and therefore beauty. This kind of mystical-ethical interpretation was typical for Hugh, who tended to find Genesis interesting for its moral lessons rather than as a literal account of events. Along with Jesus, the sacraments were divine gifts that God gave man to redeem himself, though God could have used other means. Hugh separated everything along the lines of \"opus creationis\" and \"opus restaurationis\". \"Opus Creationis\" was the works of the creation, referring to God's creative activity, the true good natures of things, and the original state and destiny of humanity. The \"opus restaurationis\" was that which dealt with the reasons for God sending Jesus and the consequences of that. Hugh believed that God did not have to send Jesus and that He had other options open to Him. Why he chose to send Jesus is a mystery we are to meditate on and is to be learned through revelation, with the aid of philosophy to facilitate understanding.", "section_level": 1}, {"title": "Legacy.", "content": "Within the Abbey of St Victor, many scholars who followed him are often known as the 'School of St Victor'. Both Achard and Andrew of St Victor appear to have been direct disciples of Hugh. Others, who probably entered the community too late to be directly educated by Hugh, include Richard of Saint Victor and Godfrey. One of Hugh's ideals that did not take root in St Victor, however, was his embracing of science and philosophy as tools for approaching God. His works are in hundreds of libraries all across Europe. He is quoted in many other publications after his death, and Bonaventure praises him in \"De reductione artium ad theologiam\". He was also an influence on the critic Erich Auerbach, who cited this passage from Hugh of St Victor in his essay \"Philology and World Literature\": It is therefore, a source of great virtue for the practiced mind to learn, bit by bit, first to change about in visible and transitory things, so that afterwards it may be able to leave them behind altogether. The person who finds his homeland sweet is a tender beginner; he to whom every soil is as his native one is already strong; but he is perfect to whom the entire world is as a foreign place.

At the request of the East Frankish king Henry the Fowler, who wished to stake a claim to equality and to seal the alliance between the two Saxon kingdoms, her half-brother King Æthelstan sent his sisters Edith and Edgiva to Germany. Henry's eldest son and heir to the throne Otto was instructed to choose whichever one pleased him best. Otto chose Edith, according to Hrotsvitha a woman \"of pure noble countenance, graceful character and truly royal appearance\", and married her in 930. In 936 Henry the Fowler died and his eldest son Otto, Edith's husband, was crowned king at Aachen Cathedral. A surviving report of the ceremony by the medieval chronicler Widukind of Corvey makes no mention of his wife having been crowned at this point, but according to Bishop Thietmar of Merseburg's chronicle, Eadgyth was nevertheless anointed as queen, albeit in a separate ceremony. As queen consort, Edith undertook the usual state duties of a \"First Lady\": when she turns up in the records it is generally in connection with gifts to the state's favoured monasteries or memorials to holy women and saints. In this respect she seems to have been more diligent than her now widowed and subsequently sainted mother-in-law, Queen Matilda, whose own charitable activities only achieve a single recorded mention from the period of Eadgyth's time as queen. There was probably rivalry between the Benedictine founded at Magdeburg by Otto and Eadgyth in 937, a year after coming to the throne, and Matilda's foundation Quedlinburg Abbey, intended by her as a memorial to her husband, the late King Henry. Edith accompanied her husband on his travels, though not during battles. While Otto fought against the rebellious dukes Eberhard of Franconia and Gilbert of Lorraine in 939, she spent the hostilities at Lorsch Abbey. Like her brother, Æthelstan, Edith was devoted to the cult of their ancestor Saint Oswald of Northumbria and was instrumental in introducing this cult into Germany after her marriage to the emperor. Her lasting influence may have caused certain monasteries and churches in the Duchy of Saxony to be dedicated to this saint.

After his mother's early death, Ansgar was brought up in Corbie Abbey, and was educated at the Benedictine monastery in Picardy. According to the \"Vita Ansgarii\" (\"Life of Ansgar\"), when the little boy learned in a vision that his mother was in the company of Mary, mother of Jesus, his careless attitude toward spiritual matters changed to seriousness. His pupil, successor, and eventual biographer Rimbert considered the visions (of which this was the first) to have been Ansgar's main life motivator. Ansgar was a product of the phase of Christianization of Saxony (present day Northern Germany) begun by Charlemagne and continued by his son and successor, Louis the Pious. In 822 Ansgar became one of many missionaries sent to found the abbey of Corvey (New Corbie) in Westphalia, where he became a teacher and preacher. A group of monks including Ansgar were sent further north to Jutland with the king Harald Klak, who had received baptism during his exile. With Harald's downfall in 827 and Ansgar's companion Autbert having died, their school for the sons of courtiers closed and Ansgar returned to Germany. Then in 829, after the Swedish king Björn at Hauge requested missionaries for his Swedes, King Louis sent Ansgar, now accompanied by friar Witmar from New Corbie as his assistant. Ansgar preached and made converts, particularly during six months at Birka, on Lake Mälaren, where the wealthy widow Mor Frideborg extended hospitality. Ansgar organized a small congregation with her and the king's steward, Hergeir, as its most prominent members. In 831 Ansgar returned to Louis' court at Worms and was appointed to the Archbishopric of Hamburg-Bremen. This was a new archbishopric, incorporating the bishoprics of Bremen and Verden and with the right to send missions into all the northern lands, as well as to consecrate bishops for them. Ansgar received the mission of evangelizing pagan Denmark, Norway and Sweden. The King of Sweden decided to cast lots as to whether to admit the Christian missionaries into his kingdom. Ansgar recommended the issue to the care of God, and the lot was favorable. Ansgar was consecrated as a bishop in November 831, with the approval of Gregory IV. Before traveling north once again, Ansgar traveled to Rome to receive the pallium directly from the pope's hands, and was formally named legate for the northern lands. Ebbo, Archbishop of Reims had previously received a similar commission, but would be deposed twice before his death in 851, and never actually traveled so far north, so the jurisdiction was divided by agreement, with Ebbo retaining Sweden for himself. For a time Ansgar devoted himself to the needs of his own diocese, which was still missionary territory and had few churches. He founded a monastery and a school in Hamburg. Although intended to serve the Danish mission further north, it accomplished little. After Louis the Pious died in 840, his empire was divided and Ansgar lost the abbey of Turholt, which Louis had given to endow Ansgar's work. Then in 845, the Danes unexpectedly raided Hamburg, destroying all the church's treasures and books. Ansgar now had neither see nor revenue, and many helpers deserted him. The new king, Louis' third son, Louis the German, did not re-endow Turholt to Ansgar, but in 847 he named the missionary to the vacant diocese of Bremen, where Ansgar moved in 848. However, since Bremen had been suffragan to the Bishop of Cologne, combining the sees of Bremen and Hamburg presented canonical difficulties. After prolonged negotiations, Pope Nicholas I would approve the union of the two dioceses in 864. Through this political turmoil, Ansgar continued his northern mission. The Danish civil war compelled him to establish good relations with two kings, Horik the Elder and his son, Horik II. Both assisted him until his death; Ansgar was able to secure permission to build a church in Sleswick north of Hamburg and recognition of Christianity as a tolerated religion. Ansgar did not forget the Swedish mission, and spent two years there in person (848–850), averting a threatened pagan reaction. In 854, Ansgar returned to Sweden when king Olof ruled in Birka.

It is partly concerned with Ansgar's visions, which, according to the author Rimbert, encouraged and assisted Ansgar's remarkable missionary feats. Through the course of this work, Ansgar repeatedly embarks on a new stage in his career following a vision. According to Rimbert, his early studies and ensuing devotion to the ascetic life of a monk were inspired by a vision of his mother in the presence of Mary, mother of Jesus. Again, when the Swedish people were left without a priest for some time, he begged King Horik to help him with this problem; then after receiving his consent, consulted with Bishop Gautbert to find a suitable man. The two together sought the approval of King Louis, which he granted when he learned that they were in agreement on the issue. Ansgar was convinced he was commanded by heaven to undertake this mission and was influenced by a vision he received when he was concerned about the journey, in which he met a man who reassured him of his purpose and informed him of a prophet that he would meet, the abbot Adalhard, who would instruct him in what was to happen. In the vision, he searched for and found Adalhard, who commanded, \"Islands, listen to me, pay attention, remotest peoples\", which Ansgar interpreted as God's will that he go to the Scandinavian countries as \"most of that country consisted of islands, and also, when 'I will make you the light of the nations so that my salvation may reach to the ends of the earth' was added, since the end of the world in the north was in Swedish territory\".

It was simply a roughly oval piece of cloth, with a round hole in the middle through which to pass the head, that fell below the knees on all sides. It had to be gathered up on the arms to allow the arms to be used freely. In its liturgical use in the West, this garment was folded up from the sides to leave the hands free. Strings were sometimes used to assist in this task, and the deacon could help the priest in folding up the sides of the vestment. Beginning in the 13th century, there was a tendency to shorten the sides a little. In the course of the 15th and the following century, the chasuble took something like its modern form, in which the sides of the vestment no longer reach to the ankle but only, at most, to the wrist, making folding unnecessary. At the end of the sixteenth century the chasuble, though still quite ample and covering part of the arms, had become less similar to its traditional shape than to that which prevailed in the nineteenth and early twentieth centuries, when the chasuble was reduced to a broad scapular, leaving the whole of the arms quite free, and was shortened also in front and back. Additionally, to make it easier for the priest to join his hands when wearing a chasuble of stiff (lined and heavily embroidered) material, in these later centuries the front was often cut away further, giving it the distinctive shape often called \"fiddleback\". Complex decoration schemes were often used on chasubles of scapular form, especially the back, incorporating the image of the Christian cross or of a saint; and rich materials such as silk, cloth of gold or brocade were employed, especially in chasubles reserved for major celebrations.", "section_level": 1}, {"title": "Current usage.", "content": "In the 20th century, there began to be a return to an earlier, more ample, form of the chasuble, sometimes called \"Gothic\", as distinguished from the \"Roman\" scapular form.

There exists a photograph of Pope Pius XI wearing the more ample chasuble while celebrating Mass in Saint Peter's Basilica as early as 19 March 1930. After the Second Vatican Council, the more ample form became the most usually seen form of the chasuble, and the directions of the GIRM quoted above indicate that \"it is fitting\" that the beauty should come \"not from abundance of overly lavish ornamentation, but rather from the material that is used and from the design. Ornamentation on vestments should, moreover, consist of figures, that is, of images or symbols, that evoke sacred use, avoiding thereby anything unbecoming\" (n. 344). Hence, the prevalence today of chasubles that reach almost to the ankles, and to the wrists, and decorated with relatively simple symbols or bands and orphreys. By comparison, \"fiddleback\" vestments were often extremely heavily embroidered or painted with detailed decorations or whole scenes depicted. Use of scapular \"Roman\" chasubles, whether with straight edges or in \"fiddleback\" form, is sometimes associated with traditionalism. However, some priests prefer them simply on grounds of taste and comfort, while for similar reasons some traditionalist priests prefer ampler chasubles of less stiff material. Pope Benedict XVI sometimes used chasubles of the transitional style common at the end of the 16th century.

Nearly all ecclesiologists are now agreed that liturgical costume was simply an adaptation of the secular attire commonly worn throughout the Roman Empire in the early Christian centuries.

The state sponsored employment organisation provided services to civic and land improvement projects, from 16 July 1932 it was headed by Friedrich Syrup in the official rank of a \"Reichskommissar\". As the name stated, participating was voluntary as long as the Weimar Republic existed. The concept was adopted by Adolf Hitler, who upon the Nazi seizure of power in 1933 appointed Konstantin Hierl state secretary in the Reich Ministry of Labour, responsible for FAD matters. Hierl was already a high-ranking member of the NSDAP and head of the party's labour organisation, the \"Nationalsozialistischer Arbeitsdienst\" or NSAD. Hierl developed the concept of a state labour service organisation similar to the \"Reichswehr\" army, with a view to implementing a compulsory service. Meant as an evasion of the regulations set by the 1919 Treaty of Versailles, voluntariness initially was maintained after protests by the Geneva World Disarmament Conference. Hierl's rivalry with Labour Minister Franz Seldte led to the affiliation of his office as a FAD \"Reichskommissar\" with the Interior Ministry under his party fellow Wilhelm Frick. On 11 July 1934, the NSAD was renamed \"Reichsarbeitsdienst\" or RAD with Hierl as its director until the end of World War II.

The most widely cultivated clovers are white clover, \"Trifolium repens\", and red clover, \"Trifolium pratense\". Clover, either sown alone or in mixture with ryegrass, has for a long time formed a staple crop for silaging, for several reasons: it grows freely, shooting up again after repeated mowings; it produces an abundant crop; it is palatable to and nutritious for livestock; it fixes nitrogen, reducing the need for synthetic fertilizers; it grows in a great range of soils and climates; and it is appropriate for either pasturage or green composting. In many areas, particularly on acidic soil, clover is short-lived because of a combination of insect pests, diseases and nutrient balance; this is known as \"clover sickness\". When crop rotations are managed so that clover does not recur at intervals shorter than eight years, it grows with much of its pristine vigor. Clovers are most efficiently pollinated by bumblebees, which have declined as a result of agricultural intensification. Honeybees can also pollinate clover, and beekeepers are often in heavy demand from farmers with clover pastures. Farmers reap the benefits of increased reseeding that occurs with increased bee activity, which means that future clover yields remain abundant. Beekeepers benefit from the clover bloom, as clover is one of the main nectar sources for honeybees. \"Trifolium repens\", white or Dutch clover, is a perennial abundant in meadows and good pastures. The flowers are white or pinkish, becoming brown and deflexed as the corolla fades. \"Trifolium hybridum\", alsike or Swedish clover, is a perennial which was introduced early in the 19th century and has now become naturalized in Britain. The flowers are white or rosy, and resemble those of \"Trifolium repens\". \"Trifolium medium\", meadow or zigzag clover, a perennial with straggling flexuous stems and rose-purple flowers, has potential for interbreeding with \"T. pratense\" to produce perennial crop plants.

Under the feudal system, most land in England was cultivated in common fields, where peasants were allocated strips of arable land that were used to support the needs of the local village or manor. By the sixteenth century the growth of population and prosperity provided incentives for landowners to use their land in more profitable ways, dispossessing the peasantry. Common fields were aggregated and enclosed by large and enterprising farmers—either through negotiation among one another or by lease from the landlord—to maximize the productivity of the available land and contain livestock. Fences redefined the means by which land is used, resulting in the modern law of servitudes. In the United States, the earliest settlers claimed land by simply fencing it in. Later, as the American government formed, unsettled land became technically owned by the government and programs to register land ownership developed, usually making raw land available for low prices or for free, if the owner improved the property, including the construction of fences. However, the remaining vast tracts of unsettled land were often used as a commons, or, in the American West, \"open range\" as degradation of habitat developed due to overgrazing and a tragedy of the commons situation arose, common areas began to either be allocated to individual landowners via mechanisms such as the Homestead Act and Desert Land Act and fenced in, or, if kept in public hands, leased to individual users for limited purposes, with fences built to separate tracts of public and private land. Ownership of a fence on a boundary varies. The last relevant original title deed(s) and a completed seller's property information form may document which side has to put up and has installed any fence respectively; the first using \"T\" marks/symbols (the side with the \"T\" denotes the owner); the latter by a ticked box to the best of the last owner's belief with no duty, as the conventionally agreed conveyancing process stresses, to make any detailed, protracted enquiry. Commonly the mesh or panelling is in mid-position. Otherwise it tends to be on non-owner's side so the fence owner might access the posts when repairs are needed but this is not a legal requirement. Where estate planners wish to entrench privacy a close-boarded fence or equivalent well-maintained hedge of a minimum height may be stipulated by deed. Beyond a standard height planning permission is necessary. Where a rural fence or hedge has (or in some cases had) an adjacent ditch, the ditch is normally in the same ownership as the hedge or fence, with the ownership boundary being the edge of the ditch furthest from the fence or hedge. The principle of this rule is that an owner digging a boundary ditch will normally dig it up to the very edge of their land, and must then pile the spoil on their own side of the ditch to avoid trespassing on their neighbour. They may then erect a fence or hedge on the spoil, leaving the ditch on its far side. Exceptions exist in law, for example where a plot of land derives from subdivision of a larger one along the centre line of a previously-existing ditch or other feature, particularly where reinforced by historic parcel numbers with acreages beneath which were used to tally up a total for administrative units not to confirm the actual size of holdings, a rare instance where Ordnance Survey maps often provide more than circumstantial evidence namely as to which feature is to be considered the boundary. On private land in the United Kingdom, it is the landowner's responsibility to fence their livestock in. Conversely, for common land, it is the surrounding landowners' duty to fence the common's livestock out such as in large parts of the New Forest. Large commons with livestock roaming have been greatly reduced by 18th and 19th century Acts for enclosure of commons covering most local units, with most remaining such land in the UK's National Parks.", "section_level": 2}, {"title": "United States.", "content": "Distinctly different land ownership and fencing patterns arose in the eastern and western United States.

The \"open range\" tradition of requiring landowners to fence out unwanted livestock was dominant in most of the rural west until very late in the 20th century, and even today, a few isolated regions of the west still have open range statutes on the books. More recently, fences are generally constructed on the surveyed property line as precisely as possible. Today, across the nation, each state is free to develop its own laws regarding fences.

Some scholars speculate that Thutmose ousted his older brother in order to usurp power and then commissioned the \"Dream Stele\" in order to justify his unexpected kingship. Thutmose's most celebrated accomplishment was the restoration of the Sphinx at Giza and subsequent commission of the \"Dream Stele\". According to Thutmose's account on the \"Dream Stele\", while the young prince was out on a hunting trip, he stopped to rest under the head of the Sphinx, which was buried up to the neck in sand. He soon fell asleep and had a dream in which the Sphinx told him that if he cleared away the sand and restored it he would become the next Pharaoh. After completing the restoration of the Sphinx, he placed a carved stone tablet, now known as the \"Dream Stele\", between the two paws of the Sphinx. The restoration of the Sphinx, and the text of the \"Dream Stele\" would then be a piece of propaganda on Thutmose's part, meant to bestow legitimacy upon his unexpected kingship. Little is known about his brief ten-year rule. He suppressed a minor uprising in Nubia in his 8th year (attested in his Konosso stela) around 1393 BC and was referred to in a stela as the \"Conqueror of Syria\", but little else has been pieced together about his military exploits. Betsy Bryan, who penned a biography of Thutmose IV, says that Thutmose IV's Konosso stela appears to refer to a minor desert patrol action on the part of the king's forces to protect certain gold-mine routes in Egypt's Eastern Desert from occasional attacks by the Nubians. Thutmose IV's rule is significant because he established peaceful relations with Mitanni and married a Mitannian princess to seal this new alliance.

Thutmose's grandfather Thutmose III almost certainly acceded the throne in either 1504 or 1479, based upon two lunar observances during his reign, and ruled for nearly 54 years. His successor Amenhotep II, Thutmose IV's father, took the throne and ruled for at least 26 years but has been assigned up to 35 years in some chronological reconstructions. The currently preferred reconstruction, after analyzing all this evidence, usually comes to an accession date around 1401 BC or 1400 BC for the beginning of Thutmose IV's reign. The length of his reign is not as clear as one would wish. He is usually given about nine or ten years of reign. Manetho credits him a reign of 9 years and 8 months. However, Manetho's other figures for the 18th Dynasty are frequently assigned to the wrong kings or simply incorrect, so monumental evidence is also used to determine his reign length. Of all of Thutmose IV's dated monuments, three date to his first regnal year, one to his fourth, possibly one to his fifth, one to his sixth, two to his seventh, and one to his eighth. Two other dated objects, one dated to a Year 19 and another year 20, have been suggested as possibly belonging to him, but neither have been accepted as dating to his reign.

A discretionary policy is supported because it allows policymakers to respond quickly to events. However, discretionary policy can be subject to dynamic inconsistency: a government may say it intends to raise interest rates indefinitely to bring inflation under control, but then relax its stance later. This makes policy non-credible and ultimately ineffective. A rule-based policy can be more credible, because it is more transparent and easier to anticipate. Examples of rule-based policies are fixed exchange rates, interest rate rules, the stability and growth pact and the Golden Rule. Some policy rules can be imposed by external bodies, for instance the Exchange Rate Mechanism for currency. A compromise between strict discretionary and strict rule-based policy is to grant discretionary power to an independent body. For instance, the Federal Reserve Bank, European Central Bank, Bank of England and Reserve Bank of Australia all set interest rates without government interference, but do not adopt rules.

A government could raise money through taxing its citizens. However, it could now also debase the coinage and so increase the money supply. Early civilizations also made decisions about whether to permit and how to tax trade. Some early civilizations, such as Ptolemaic Egypt adopted a closed currency policy whereby foreign merchants had to exchange their coin for local money. This effectively levied a very high tariff on foreign trade. By the early modern age, more policy choices had been developed. There was considerable debate about mercantilism and other restrictive trade practices like the Navigation Acts, as trade policy became associated with both national wealth and with foreign and colonial policy.

AKS involves neuronal loss, that is, damage to neurons; gliosis, which is a result of damage to supporting cells of the central nervous system, and hemorrhage or bleeding also occurs in mammillary bodies. Damage to the medial dorsal nucleus or anterior group of the thalamus (limbic-specific nuclei) is also associated with this disorder. Cortical dysfunction may have arisen from thiamine deficiency, alcohol neurotoxicity, and/or structural damage in the diencephalon. Originally, it was thought that a lack of initiative and a flat affect were important characteristics of emotional presentation in sufferers. Studies have questioned this, proposing that neither is necessarily a symptom of AKS. Research suggesting that Korsakoff patients are emotionally unimpaired has made this a controversial topic. It can be argued that apathy, which usually characterizes Korsakoff patients, reflects a deficit of emotional \"expressions\", without affecting the \"experience\" or perception of emotion. AKS causes deficits in declarative memory in most patients, but leaves implicit spatial, verbal, and procedural memory functioning intact. People with AKS have deficits in the processing of contextual information. Context memories refers to the where and when of experiences, and is an essential part of recollection. The ability to store and retrieve this information, such as spatial location or temporal order information, is impaired. Research has also suggested that Korsakoff patients have impaired executive functions, which can lead to behavioral problems and interfere with daily activities. It is unclear, however, which executive functions are affected most. Nonetheless, IQ is usually not affected by the brain damage associated with Korsakoff's syndrome. At first it was thought that AKS patients used confabulation to fill in memory gaps. However, it has been found that confabulation and amnesia do not necessarily co-occur. Studies have shown that there is dissociation between provoked confabulation, spontaneous confabulation (which is unprovoked), and false memories. That is, patients could be led to believe certain things had happened which actually had not, but so could people without alcoholic Korsakoff syndrome.", "section_level": 1}, {"title": "Causes.", "content": "Conditions resulting in thiamine deficiency and its effects include chronic alcoholism and severe malnutrition. Alcoholism may co-occur with poor nutrition, which in addition to inflammation of the stomach lining, causes thiamine deficiency. Other causes include dietary deficiencies, prolonged vomiting, eating disorders, and the effects of chemotherapy. It can also occur in pregnant women who have a form of extreme morning sickness known as hyperemesis gravidarum. Mercury poisoning can also lead to Korsakoff's syndrome. Though it does not always co-occur, this disorder can emerge frequently as a consequential result of Wernicke's encephalopathy. PET scans show that there is a decrease of glucose metabolism in the frontal, parietal and cingulated regions of the brain in Korsakoff's patients. This may contribute to memory loss and amnesia. Structural neuroimaging has also shown the presence of midline diencephalic lesions and cortical atrophy. Structural lesions of the central nervous system, though rare, can also contribute to symptoms of AKS. Severe damage to the medial dorsal nucleus inevitably results in memory deficit. Additionally, autopsies of patients with AKS have showed lesions in both the midline and anterior thalamus, and thalamic infarctions. Bilateral infarctions to the thalamus can result in Korsakoff-induced amnesia as well. These findings imply damage to anterior thalamic nuclei can result in disruptive memory.", "section_level": 1}, {"title": "Risk factors.", "content": "A number of factors may increase a person's risk to develop alcoholic Korsakoff syndrome.

Thus, fortifying foods with thiamine, or requiring companies that sell alcoholic beverages to supplement them with B vitamins in general or thiamine in particular, could avert many cases of AKS.", "section_level": 1}, {"title": "Treatment.", "content": "It was once assumed that anyone suffering from AKS would eventually need full-time care. This is still often the case, but rehabilitation can help regain some, albeit often limited, level of independence. Treatment involves the replacement or supplementation of thiamine by intravenous (IV) or intramuscular (IM) injection, together with proper nutrition and hydration. However, the amnesia and brain damage caused by the disease does not always respond to thiamine replacement therapy. In some cases, drug therapy is recommended. Treatment of the patient typically requires taking thiamine orally for 3 to 12 months, though only about 20 percent of cases are reversible. If treatment is successful, improvement will become apparent within two years, although recovery is slow and often incomplete. As an immediate form of treatment, a pairing of IV or IM thiamine with a high concentration of B-complex vitamins can be administered three times daily for period of 2–3 days. In most cases, an effective response from patients will be observed. A dose of 1 gram of thiamine can also be administered to achieve a clinical response. In patients who are seriously malnourished, the sudden availability of glucose without proper bodily levels of thiamine to metabolize is thought to cause damage to cells. Thus, the administration of thiamine along with an intravenous form of glucose is often good practice. Treatment for the memory aspect of AKS can also include domain-specific learning, which when used for rehabilitation is called the method of vanishing cues. Such treatments aim to use patients' intact memory processes as the basis for rehabilitation. Patients who used the method of vanishing cues in therapy were found to learn and retain information more easily.

Historical documents regarding the first centuries of the town are scarce. King Louis II granted the town and château of Bohumín to George, Margrave of Brandenburg-Ansbach in 1523. The town began to develop during rule by the House of Hohenzollern, although further development of Bogumin was halted by frequent epidemics of bubonic plague and floodings of the Olza. It was officially known in German as \"Oderberg\", and by the end of the 16th century the majority of citizens followed Protestantism. The successor after the Hohenzollerns in 1620 was Lazar Henckel, whose family of bankers and entrepreneurs hailed from Habsburg-ruled Hungary. In 1624 only 138 permanent residents lived in the town. After defeating Maria Theresa of Austria during the Silesian Wars, King Frederick II of Prussia annexed most of Silesia, although Oderberg remained in Austrian Silesia. The town successively became part of the Austrian Empire (1804) and Austria-Hungary (1867). After the Revolutions of 1848 in the Austrian Empire a modern municipal division was introduced in the re-established Austrian Silesia. The town became a seat of a legal district at first in Friedek and since 1868 in the Freistadt political district. At the end of the 19th century a wire and rolling mill was built by German industrialists from Berlin, Albert Hahn and Heinrich Eisner. In 1872 the important Kassa-Oderberg railway line was opened to traffic in a nearby Schönichel (Šunychl), which later outgrew Oderberg; this increased the town's importance and contributed to the Polish - Czechoslovak dispute over Cieszyn Silesia after World War I. According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the town grew from 1,839 in 1880 to 5,810 in 1910. The dominant language spoken \"colloquially\" shifted through the censuses. In 1880 and 1890 the majority were Polish-speakers (58.1% in 1880 and 64.8% in 1890), followed by German-speakers (34.8% in 1880 and 27.6% in 1890) and Czech-speakers (6.9% in 1880 and 7.6% in 1890). In 1900 and 1910 the majority were German-speakers (52.8% in 1900, 54.5% in 1910), followed by Polish-speakers (41.7% in 1900 and 38.2% in 1910) and Czech-speakers (5.3% in 1900 and 7.3% in 1910). In terms of religion, in 1910 the majority were Roman Catholics (91.7%), followed by Protestants (206 or 3.5%), Jews (129 or 2.2%) and \"others\" (141 or 2.6%). After the division of Cieszyn Silesia in 1920, the town became part of Czechoslovakia. Following the Munich Agreement, Bohumín and the Zaolzie region were annexed by Poland in October 1938. The town was then annexed by Nazi Germany at the beginning of World War II. On 1 May 1945 Bohumín was taken by Soviet troops of the 1st Guards Army.

For instance, some uses of water divert it from its natural course but return most or all of it (e.g. hydroelectric plants), while others consume much of what they take (ice, agriculture), and still others use water without diverting it at all (e.g. boating). Each type of activity has its own needs and can in theory be regulated separately. There are several types of conflict likely to arise: absolute shortages; shortages in a particular time or place, diversions of water that reduce the flow available to others, pollutants or other changes (such as temperature or turbidity) that render water unfit for others' use, and the need to maintain \"in-stream flows\" of water to protect the natural ecosystem.

Extensive archeological evidence has been found in the present-day Burgundy region of France. The Camargue breed was appreciated by the Celtic and Roman invaders who entered the Iberian Peninsula. Their genealogy is closely tied with Iberian horses, especially those of the northern part of the peninsula. The original Spanish \"jaca\" was probably a cross between the Celtic pony and the Camargue. It was later improved by crosses with northern European horse types and ultimately with the southern peninsular horse, as the Moors spread their influence toward the Pyrenees. As a result, the Camargue genes probably penetrated the Americas through the influence of the \"jaca\", the warhorse taken to new lands where hardiness was a requirement. Breeds such as the Chilean horse and Criollo show signs of some characteristics that are common in the Camargue breed. Camargue horses were used on a large scale during the construction of the Suez Canal in the 1860s. In 1976, to preserve the standards and purity of the breed, the French government set breed standards and started registering the main breeders of the Camargue horse. In 1978, they set up the breed stud book. To be registered, foals must be born out of doors and must be seen to suckle from a registered mare as proof of parentage. Foals born inside the defined Camargue region are registered, while those born elsewhere are registered (\"outside the cradle\" or \"birthplace\"). They have the heavy, square heads of primitive horses, but the influence of Arabian, Barb and Thoroughbred blood can also be seen.

A \"comune\" of its Metropolitan City, located at the southern entrance of the Strait of Messina, is to this day called 'Scaletta Zanclea'. Solinus write that the city of Metauros was established by people from the Zancle. In the early 5th century BC, Anaxilas of Rhegium renamed it Messene () in honour of the Greek city Messene (See also List of traditional Greek place names). Later, Micythus was the ruler of Rhegium and Zancle, and he also founded the city of Pyxus. The city was sacked in 397 BC by the Carthaginians and then reconquered by Dionysius I of Syracuse. In 288 BC the Mamertines seized the city by treachery, killing all the men and taking the women as their wives. The city became a base from which they ravaged the countryside, leading to a conflict with the expanding regional empire of Syracuse. Hiero II, tyrant of Syracuse, defeated the Mamertines near Mylae on the Longanus River and besieged Messina. Carthage assisted the Mamertines because of a long-standing conflict with Syracuse over dominance in Sicily. When Hiero attacked a second time in 264 BC, the Mamertines petitioned the Roman Republic for an alliance, hoping for more reliable protection. Although initially reluctant to assist lest it encourage other mercenary groups to mutiny, Rome was unwilling to see Carthaginian power spread further over Sicily and encroach on Italy. Rome therefore entered into an alliance with the Mamertines. In 264 BC, Roman troops were deployed to Sicily, the first time a Roman army acted outside the Italian Peninsula. At the end of the First Punic War it was a free city allied with Rome. In Roman times Messina, then known as Messana, had an important pharos (lighthouse). Messana was the base of Sextus Pompeius, during his war against Octavian. After the fall of the Western Roman Empire, the city was successively ruled by Goths from 476, then by the Byzantine Empire in 535, by the Arabs in 842, and in 1061 by the Norman brothers Robert Guiscard and Roger Guiscard (later count Roger I of Sicily). In 1189 the English King Richard I (\"\"The Lionheart\"\") stopped at Messina en route to the Holy Land for the Third Crusade and briefly occupied the city after a dispute over the dowry of his sister, who had been married to William the Good, King of Sicily. In 1345 Orlando d'Aragona, illegitimate son of Frederick II of Sicily was the \"strategos\" of Messina. In 1347, Messina was one of the first points of entry for the black death into Western Europe. Genoese galleys traveling from the infected city of Kaffa carried plague into the Messina ports. Kaffa had been infected via Asian trade routes and siege from infected Mongol armies led by Janibeg; it was a departure point for many Italian merchants who fled the city to Sicily. Contemporary accounts from Messina tell of the arrival of \"Death Ships\" from the East, which floated to shore with all the passengers on board already dead or dying of plague. Plague-infected rats probably also came aboard these ships. The black death ravaged Messina, and rapidly spread northward into mainland Italy from Sicily in the following few months. In 1548 St. Ignatius founded there the first Jesuit college in the world, which later gave birth to the \"Studium Generale\" (the current University of Messina). The Christian ships that won the Battle of Lepanto (1571) left from Messina: the Spanish author Miguel de Cervantes, who took part in the battle, recovered for some time in the \"Grand Hospital\". The city reached the peak of its splendour in the early 17th century, under Spanish domination: at the time it was one of the ten greatest cities in Europe. In 1674 the city rebelled against the foreign garrison. It managed to remain independent for some time, thanks to the help of the French king Louis XIV, but in 1678, with the Peace of Nijmegen, it was reconquered by the Spaniards and sacked: the university, the senate and all the privileges of autonomy it had enjoyed since the Roman times were abolished. A massive fortress was built by the occupants and Messina decayed steadily. In 1743, 48,000 died of a second wave of plague in the city. In 1783, an earthquake devastated much of the city, and it took decades to rebuild and rekindle the cultural life of Messina. In 1847 it was one of the first cities in Italy where Risorgimento riots broke out. In 1848 it rebelled openly against the reigning Bourbons, but was heavily suppressed again. Only in 1860, after the Battle of Milazzo, the Garibaldine troops occupied the city. One of the main figures of the unification of Italy, Giuseppe Mazzini, was elected deputy at Messina in the general elections of 1866. Another earthquake of less intensity damaged the city on 16 November 1894. The city was almost entirely destroyed by an earthquake and associated tsunami on the morning of 28 December 1908, killing about 100,000 people and destroying most of the ancient architecture. The city was largely rebuilt in the following year. It incurred further damage from the massive Allied air bombardments of 1943; before and during the Allied invasion of Sicily. Messina, owing to its strategic importance as a transit point for Axis troops and supplies sent to Sicily from mainland Italy, was a prime target for the British and American air forces, which dropped some 6,500 tons of bombs in the span of a few months. These raids destroyed one third of the city, and caused 854 deaths among the population. The city was awarded a Gold Medal of Military Valor and one for Civil Valor by the Italian government in memory of the event and the subsequent effort of reconstruction. In June 1955, Messina was the location of the Messina Conference of Western European foreign ministers which led to the creation of the European Economic Community. The conference was held mainly in Messina's City Hall building (), and partly in nearby Taormina.

The molars are large and, unusually, do not appear all at once but a pair at a time at the back of the mouth as the animal ages, eventually becoming worn down by the tough, abrasive grasses and falling out. Like many Macropodiformes, early kangaroos had plagiaulacoids, but these converted into normal molars in more derived species. Most species have four molars and, when the last pair is too worn to be of use, the animals starve to death. The dental formula for macropods is. Like the eutherian ruminants of the Northern Hemisphere (sheep, cattle, and so on), macropods have specialised digestive systems that use a high concentration of bacteria, protozoans, and fungi in the first chamber of a complex stomach to digest plant material. The details of organisation are quite different, but the end result is somewhat similar, namely feces. The particular structure-function relationship of the Macropodidae gut and the gut microbiota allows the degradation of lignocellulosic material with a relatively low emission of methane relative to other ruminants. These low emissions are partly explained by the anatomical differences between the macropodid digestive system and that of ruminants, resulting in shorter retention times of particulate digesta within the foregut. This fact might prevent the establishment of methanogenic archaea, which has been found in low levels in tammar wallabies (\"Macropus eugenii\") and eastern grey kangaroo (\"M. giganteus\"). Metagenomic analysis revealed that the foregut of tammar wallabies mainly contains bacteria belonging to the phyla Firmicutes, Bacteroides, and Proteobacteria. Among proteobacteria populations of the Succinivibrionaceae family are overrepresented and may contribute to low methane emissions. Macropods vary in size considerably, but most have very large hind legs and long, powerfully muscled tails. The term macropod comes from the Greek for \"large foot\" and is appropriate: most have very long, narrow hind feet with a distinctive arrangement of toes. The fourth toe is very large and strong, the fifth toe moderately so; the second and third are fused; and the first toe is usually missing. Their short front legs have five separate digits. Some macropods have seven carpal bones instead of the usual eight in mammals. All have relatively small heads and most have large ears, except for tree-kangaroos, which must move quickly between closely spaced branches. The young are born very small and the pouch opens forward. The unusual development of the hind legs is optimised for economical long-distance travel at fairly high speed. The greatly elongated feet provide enormous leverage for the strong legs, but the famous kangaroo hop has more: kangaroos and wallabies have a unique ability to store elastic strain energy in their tendons. In consequence, most of the energy required for each hop is provided \"free\" by the spring action of the tendons (rather than by muscular effort). The main limitation on a macropod's ability to leap is not the strength of the muscles in the hindquarters, it is the ability of the joints and tendons to withstand the strain of hopping. In addition, the hopping action is linked to breathing. As the feet leave the ground, air is expelled from the lungs by what amounts to an internal piston; bringing the feet forward ready for landing fills the lungs again, providing further energy efficiency. Studies of kangaroos and wallabies have demonstrated that, beyond the minimum energy expenditure required to hop at all, increased speed requires very little extra effort (much less than the same speed increase in, say, a horse, a dog, or a human), and also that little extra energy is required to carry extra weight – something that is of obvious importance to females carrying large pouch young. The ability of larger macropods to survive on poor-quality, low-energy feed, and to travel long distances at high speed without great energy expenditure (to reach fresh food supplies or waterholes, and to escape predators) has been crucial to their evolutionary success on a continent that, because of poor soil fertility and low, unpredictable average rainfall, offers only very limited primary plant productivity. Gestation in macropods lasts about a month, being slightly longer in the largest species. Typically, only a single young is born, weighing less than at birth. They soon attach themselves to one of four teats inside the mother's pouch. The young leave the pouch after five to 11 months, and are weaned after a further two to six months.

In 1966 a special issue of the journal \"Communications\" proved highly influential, becoming considered a program for research into the field and even a manifesto. It included articles by Barthes, Claude Brémond, Genette, Greimas, Todorov and others, which in turn often referred to the works of Vladimir Propp (1895–1970). Jonathan Culler (2001) describes narratology as comprising many strands implicitly united in the recognition that narrative theory requires a distinction between \"story,\" a sequence of actions or events conceived as independent of their manifestation in discourse, and \"discourse,\" the discursive presentation or narration of events.' The Russian Formalists first proposed such a distinction, employing the couplet fabula and sujet. A subsequent succession of alternate pairings has preserved the essential binomial impulse, e.g. \"histoire\"/\"discours\", \"histoire\"/\"récit\", \"story\"/\"plot\". The Structuralist assumption that one can investigate fabula and sujet separately gave birth to two quite different traditions: thematic (Propp, Bremond, Greimas, Dundes, et al.) and modal (Genette, Prince, et al.) narratology. The former is mainly limited to a semiotic formalization of the sequences of the actions told, while the latter examines the manner of their telling, stressing voice, point of view, transformation of the chronological order, rhythm and frequency.

Each decision will make some parts of the text more, and others less, accessible, and you may never know the exact results of your choices; that is, exactly what you missed. The narrative structure or game-worlds of these cybertexts are compared to a labyrinth that invites the player, a term Aarseth deems more appropriate than reader, to play, explore and discover paths within these texts. Two kinds of labyrinths which are referenced by Aarseth are the unicursal labyrinth which holds one single, winding path that leads to a hidden center, and the multicursal labyrinth, synonymous with a maze, which is branching and complex with the path and direction chosen by the player.

Indeed, between 900 BC and 100 AD, sacred Delos was a major cult centre, where Dionysus is also in evidence as well as the Titaness Leto, mother of the above-mentioned twin deities. Eventually acquiring Panhellenic religious significance, Delos was initially a religious pilgrimage for the Ionians. A number of \"purifications\" were performed by the city-state of Athens in an attempt to render the island fit for the proper worship of the gods. The first took place in the 6th century BC, directed by the tyrant Pisistratus who ordered that all graves within sight of the temple be dug up and the bodies moved to another nearby island. In the 5th century BC, during the 6th year of the Peloponnesian war and under instruction from the Delphic Oracle, the entire island was purged of all dead bodies. It was then ordered that no one should be allowed to either die or give birth on the island due to its sacred importance and to preserve its neutrality in commerce, since no one could then claim ownership through inheritance. Immediately after this purification, the first quinquennial festival of the Delian games were celebrated there. Four years later, all inhabitants of the island were removed to Atramyttium in Asia as a further purification. After the Persian Wars the island became the natural meeting-ground for the Delian League, founded in 478 BC, the congresses being held in the temple (a separate quarter was reserved for foreigners and the sanctuaries of foreign deities). The League's common treasury was kept here as well until 454 BC when Pericles removed it to Athens. The island had no productive capacity for food, fiber, or timber, with such being imported. Limited water was exploited with an extensive cistern and aqueduct system, wells, and sanitary drains. Various regions operated agoras (markets). Strabo states that in 166 BC the Romans converted Delos into a free port, which was partially motivated by seeking to damage the trade of Rhodes, at the time the target of Roman hostility. In 167 or 166 BC, after the Roman victory in the Third Macedonian War, the Roman Republic ceded the island of Delos to the Athenians, who expelled most of the original inhabitants. Roman traders came to purchase tens of thousands of slaves captured by the Cilician pirates or captured in the wars following the disintegration of the Seleucid Empire. It became the center of the slave trade, with the largest slave market in the larger region being maintained here. The Roman destruction of Corinth in 146 BC allowed Delos to at least partially assume Corinth's role as the premier trading center of Greece. However, Delos' commercial prosperity, construction activity, and population waned significantly after the island was assaulted by the forces of Mithridates VI of Pontus in 88 and 69 BC, during the Mithridatic Wars with Rome. Before the end of the 1st century BC, trade routes had changed; Delos was replaced by Puteoli as the chief focus of Italian trade with the East, and as a cult-centre too it entered a sharp decline. Due to the inadequate natural sources of food and water, and the above history, unlike other Greek islands, Delos did not have an indigenous, self-supporting community of its own. As a result, in later times it was uninhabited. Since 1872 the École française d'Athènes (\"French School of Athens\") has been excavating the island, the complex of buildings of which compares with those of Delphi and Olympia. In 1990, UNESCO inscribed Delos on the World Heritage List, citing it as the \"exceptionally extensive and rich\" archaeological site which \"conveys the image of a great cosmopolitan Mediterranean port\".

It was, however, during ancient times a rather poor island with limited agricultural resources. Its inhabitants were polytheists and worshipped many gods. Mykonos came under the control of the Romans during the reign of the Roman Empire and then became part of the Byzantine Empire until the 12th century. In 1204, with the fall of Constantinople in the Fourth Crusade, Mykonos was occupied by Andrea Ghisi. The island was ravaged by the Catalans at the end of the 13th century and finally given over to direct Venetian rule in 1390. In 1537, while the Venetians still reigned, Mykonos was attacked by Hayreddin Barbarossa, the admiral of Suleiman the Magnificent and an Ottoman fleet established itself on the island. The Ottomans, under the leadership of Kapudan Pasha, imposed a system of self-governance comprising a governor and an appointed council of \"syndics\". When the castle of Tinos fell to the Ottomans in 1718, the last of the Venetians withdrew from the region. Up until the end of the 18th century, Mykonos prospered as a trading centre, attracting many immigrants from nearby islands, in addition to regular pirate raids. In June 1794 the Battle of Mykonos was fought between British and French ships in the island's main harbour.

In the 1713 Peace of Utrecht, Spain ceded its possessions in Italy and Flanders to Habsburg Austria and Savoy and recovering them was a priority for the new administration of Philip V of Spain. The 1701 to 1714 war was fought to ensure neither France or the Habsburg Monarchy could ever be united with Spain but Philip now cast doubts on his renunciation of the French throne agreed at Utrecht. Charles VI of Austria also refused to formally accept this principle, as well as delaying implementation of the Dutch Barrier in the newly acquired Austrian Netherlands, an objective for which the Dutch Republic effectively bankrupted themselves. In late 1716, former opponents Britain and France agreed an Anglo-French alliance to ensure enforcement of Utrecht; in January 1717, these two and the Dutch formed the Triple Alliance. Its key principles were confirmation by Charles and Philip that they renounced their respective claims to the thrones of France and Spain, while Savoy and Austria would exchange Sicily and Sardinia. Spain saw little benefit in this and decided to seize the opportunity to recover territorial losses agreed at Utrecht. As neither Savoy nor Austria possessed significant navies, the most obvious targets were the islands of Sardinia and Sicily, an ambition that aligned with the Italian dynastic claims of Elizabeth Farnese. In August 1717, Spanish forces landed on Sardinia and by November had re-established control of the island. They met little opposition; Austria was engaged in the 1716–1718 Austro-Turkish War, while France and the Netherlands needed peace to rebuild their shattered economies. Attempts to resolve the situation through diplomacy failed and in June 1718, a British naval force arrived in the Western Mediterranean as a preventive measure.

The Austrians were defeated in the First Battle of Milazzo on 15 October, and only held a small bridgehead around Milazzo. In 1718, Cardinal Alberoni began plotting to replace the Duc d'Orléans, regent to the 5-year old King Louis XV of France, with Philip V. This plot became known as the Cellamare Conspiracy. After the plot was discovered, Alberoni was expelled from France, which declared war on Spain. By 17 December 1718, the French, British, and Austrians had all officially entered the war against Spain. The Dutch would join them later, in August 1719. The Duc d'Orléans ordered a French army under the Duke of Berwick to invade the western Basque districts of Spain in April 1719, still under the shock of Philip V's military intervention against them. The Duke of Berwick's army met very little resistance, but was forced back by heavy losses due to disease. A second attack in Catalonia suffered the same fate. In Sicily, the Austrians started a new offensive under Count Claude Florimond de Mercy. They first suffered a defeat in the Battle of Francavilla (20 June 1719). But the Spanish were cut off from their homeland by the British fleet and it was just a matter of time before their resistance would crumble. Mercy was then victorious in the second Battle of Milazzo, took Messina in October and besieged Palermo. It was also in 1719 that the Irish exile, the Duke of Ormonde, organized an expedition with extensive Spanish support to invade Britain and replace King George I with James Stuart, the Jacobite \"Old Pretender\". However, his fleet was dispersed by a storm near Galicia in 1719, and never reached Britain.

In retaliation for this attack, a British fleet captured Vigo and marched inland to Pontevedra in October 1719.

Some studies have explored its origins in an autoimmune response, and, separately or in relation to an immune response, links to pathologies of infectious disease — viral and bacterial, e.g., in the case of influenza, where a link with encephalitis is clear. Postencephalitic parkinsonism was clearly documented to have followed an outbreak of encephalitis lethargica following the 1918 influenza pandemic; evidence for viral causation of the Parkinson's symptoms is circumstantial (epidemiologic, and finding influenza antigens in encephalitis lethargica patients), while evidence arguing against this cause is of the negative sort (e.g., lack of viral RNA in postencephalitic parkinsonian brain material). In reviewing the relationship between influenza and encephalitis lethargica (EL), McCall and coworkers conclude, as of 2008, that while \"the case against influenza [is] less decisive than currently perceived... there is little direct evidence supporting influenza in the etiology of EL,\" and that \"[a]lmost 100 years after the EL epidemic, its etiology remains enigmatic.\" Hence, while opinions on the relationship of encephalitis lethargica to influenza remain divided, the preponderance of literature appears skeptical. German neurologist Felix Stern, who examined hundreds of encephalitis lethargica patients during the 1920s, pointed out that the encephalitis lethargica typically evolved over time. The early symptom would be dominated by sleepiness or wakefulness. A second symptom would lead to an oculogyric crisis. The third symptom would be recovery, followed by a Parkinson-like symptom. If patients of Stern followed this course of disease, he diagnosed them with encephalitis lethargica. Stern suspected encephalitis lethargica to be close to polio without evidence. Nevertheless, he experimented with the convalescent serum of survivors of the first acute symptom. He vaccinated patients with early stage symptoms and told them that it might be successful. Stern is author of the 1920s definitive book \"Die Epidemische Encephalitis\" (1920 and 2nd ed. 1928). Stern was driven to suicide during the Holocaust by the German state, his research forgotten. In 2010, in a substantial Oxford University Press compendium reviewing the historic and contemporary views on EL, its editor, Joel Vilensky of the Indiana University School of Medicine, quotes Pool, writing in 1930, who states, \"we must confess that etiology is still obscure, the causative agent still unknown, the pathological riddle still unsolved...\", and goes on to offer the following conclusion, as of that publication date:Subsequent to publication of this compendium, an enterovirus was discovered in encephalitis lethargica cases from the epidemic.

He appointed Dózsa to organize and direct the movement. Within a few weeks, Dózsa had gathered an army of some 40,000 so-called \"hajdú\", consisting for the most part of peasants, wandering students, friars, and parish priests - some of the lowest-ranking groups of medieval society. They assembled in their counties, and by the time he had provided them with some military training, they began to air the grievances of their status. No measures had been taken to supply these voluntary crusaders with food or clothing. As harvest-time approached, the landlords commanded them to return to reap the fields, and, on their refusing to do so, proceeded to maltreat their wives and families and set their armed retainers upon the local peasantry. The volunteers became increasingly angry at the failure of the nobility to provide military leadership (the original and primary function of the nobility and the justification for its higher status in the society.)

The rebellion spread quickly, principally in the central or purely Magyar provinces, where hundreds of manor houses and castles were burnt and thousands of the gentry killed by impalement, crucifixion, and other methods. Dózsa's camp at Cegléd was the centre of the \"jacquerie\", as all raids in the surrounding area started out from there. In reaction, the papal bull was revoked, and King Vladislaus II issued a proclamation commanding the peasantry to return to their homes under pain of death. By this time, the uprising had attained the dimensions of a revolution; all the vassals of the kingdom were called out against it, and soldiers of fortune were hired in haste from the Republic of Venice, Bohemia, and the Holy Roman Empire. Meanwhile, Dózsa had captured the city and fortress of Csanád (today's Cenad), and signaled his victory by impaling the bishop and the castellan. Subsequently, at Arad, Lord Treasurer István Telegdy was seized and tortured to death. In general, however, the rebels only executed particularly vicious or greedy noblemen; those who freely submitted were released on parole.

Dózsa himself had apparently become demoralized by success: after Csanád, he issued proclamations which can be described as millenarian. As his suppression had become a political necessity, Dózsa was routed at Temesvár (today Timișoara, Romania) by an army of 20,000 led by John Zápolya and István Báthory. He was captured after the battle, and condemned to sit on a smouldering, heated iron throne, and forced to wear a heated iron crown and sceptre (mocking his ambition to be king). While he was suffering, a procession of nine fellow rebels who had been starved beforehand were led to this throne. In the lead was Dózsa's younger brother, Gergely, who was cut in three despite Dózsa asking for Gergely to be spared. Next, executioners removed some pliers from a fire and forced them into Dózsa's skin. After tearing his flesh, the remaining rebels were ordered to bite spots where the hot pliers had been inserted and to swallow the flesh. The three or four who refused were simply cut up, prompting the others to comply. In the end, Dózsa died from the ordeal, while the rebels who obeyed were released and left alone. The revolt was repressed but some 70,000 peasants were tortured. György's execution, and the brutal suppression of the peasants, greatly aided the 1526 Ottoman invasion as the Hungarians were no longer a politically united people. Another consequence was the creation of new laws, an effort in the Hungarian Diet led by István Werbőczy.

The year of his birth has been given as 1389, 1395 or 1403. Bessarion's Neoplatonism Bessarion was educated in Constantinople, then went in 1423 to Peloponnese to study Neoplatonism under Gemistus Pletho. Under Pletho, he \"went through the liberal arts curriculum..., with a special emphasis on mathematics...including the study of astronomy and geography\" that would have related \"philosophy to physics...cosmology and astrology\" and Pletho's “mathematics would include Pythagorean number-mysticism, Plato’s cosmological geometry and the Neoplatonic arithmetic which connected the material world with the world of Plato’s Forms. Possibly it also included astrology...\" Woodhouse also mentions that Bessarion \"had a mystical streak...[and] was proficient in Neoplatonic vocabulary...mathematics...and Platonic theology\". Bessarion's Neoplatonism stayed with him his whole life, even as a cardinal. He was very familiar with Neoplatonist terminology and used it in his letter to Pletho's two sons, Demitrios and Andronikos, on the death of his still-beloved teacher in 1452. Perhaps the most remarkable thing about his life was that a Neoplatonist could have played such a significant role in the Roman Church for at least a brief time, though he was attacked for his views by more orthodox Catholic academics shortly after his death. Bessarion's life as a monk and role in the Council of Ferrara On becoming a tonsured monk, he adopted the name of an old Egyptian anchorite Bessarion, whose story he has related. In 1436 became abbot of a monastery in Constantinople and in 1437, he was made metropolitan of Nicaea by the Byzantine Emperor John VIII Palaeologus, whom he accompanied to Italy in order to bring about a reunion between the Eastern (Orthodox) and Western (Catholic) churches. The emperor hoped to use the possibility of re-uniting the churches to obtain help from Western Europe against the Ottoman Empire. Bessarion participated in the Byzantine delegation to the Council of Ferrara-Florence as the most eminent representative of unionists, although originally belonged to the party of anti-unionists. On 6 July 1439 he was the one who read the declaration of the Greek Association of Churches in the cathedral of Florence, in the presence of Pope Eugene IV and the Emperor John VIII Palaeologus. Some have impugned Bessarion's sincerity in adhering to the Union. It has been argued that he was pragmatic patriot and thought religious Union would be the only hope and refuge for the Byzantine Empire faced with the Ottoman advance. However, Gill upholds Bessarion's sincerity in being convinced to the truth of the Roman position in the matters discussed at the Council quoting from the bishop's own \"Oratio Dogmatica\": Upon his return to the East, he found himself bitterly resented for his attachment to the minority party that saw no difficulty in a reconciliation of the two churches. At the Council of Ferrara-Florence (1438–1445), Bessarion supported the Roman church and gained the favour of Pope Eugene IV, who invested him with the rank of cardinal at a consistory of 18 December 1439. From that time, he resided permanently in Italy, doing much, by his patronage of learned men, by his collection of books and manuscripts, and by his own writings, to spread abroad the new learning. His palazzo in Rome was a virtual Academy for the studies of new humanistic learning, a center for learned Greeks and Greek refugees, whom he supported by commissioning transcripts of Greek manuscripts and translations into Latin that made Greek scholarship available to Western Europeans. He supported Regiomontanus in this fashion and defended Nicholas of Cusa. He is known in history as the original patron of the Greek exiles (scholars and diplomats) including Theodore Gaza, George of Trebizond, John Argyropoulos and many others. He held in succession the archbishopric of Siponto and the suburbicarian sees of Sabina and Frascati. At the papal conclave of 1455 which elected the Aragonese candidate, Alfons de Borja, as Callixtus III, Cardinal Bessarion was an early candidate for his disinterest in the competition between Roman factions that pressed candidates of the Orsini and Colonna factions. He was opposed for his Greek background by the French Cardinal Alain de Coëtivy. \"It is probable that the cardinals were less afraid of his Greek training and temperament than they were of his known austerity and passion for reform\", Francis A. Burkle-Young has observed. For five years (1450–1455), he was legate at Bologna, and he was engaged on embassies to many foreign princes, among others to Louis XI of France in 1471. Other missions were to Germany to encourage Western princes to help their fellow Christians in the East. For these efforts, his fellow humanist Aeneas Silvius Piccolomini, then Pius II, gave him the purely ceremonial title of Latin Patriarch of Constantinople in 1463. As \"primus Cardinalium\" (from April 1463) — the title Dean of the Sacred College of Cardinals was not yet in use — Cardinal Bessarion presided over the Papal conclave, 1464 and Papal conclave, 1471. Vexation at an insult offered him by Louis XI is said to have hastened his death, which took place on 19 November 1472 at Ravenna.

Bessarion, though a Platonist, was not so thoroughgoing in his admiration as Gemistus Pletho, and he strove instead to reconcile the two philosophies. His work, by opening up the relations of Platonism to the main questions of religion, contributed greatly to the extension of speculative thought in the department of theology. It was thanks to him that the Bibliotheca (Pseudo-Apollodorus), an important compendium of Greek Mythology, has survived to the present. His library, which contained a very extensive collection of Greek manuscripts, was presented by him in 1468 to the Senate of the Republic of Venice, and forms the nucleus of the famous library of St Mark's, the \"Biblioteca Marciana\".

The pamphlet mainly covers the period 1912–1914, and occasionally back to 1900. Lichnowsky deplored the German alliance with Austria-Hungary (though he owned land in Austria and had served as a diplomat in Vienna), feeling that it inevitably pulled German diplomacy into Balkan crises and tensions with Russia, without any compensating benefits to Germany with its new industries, trade and colonies. \"This is a return to the days of the Holy Roman Empire and the mistakes of the Hohenstaufens and Habsburgs,\" he wrote. The Kaiser had commented on 31 July 1914 about an encircling British diplomacy during the crisis: \"For I no longer have any doubt that England, Russia and France have agreed among themselves, knowing that our treaty obligations compel us to support Austria-Hungary, to use the Austro-Serb conflict as a pretext for waging a war of annihilation against us.... Our dilemma over keeping faith with the old and honourable Emperor has been exploited to create a situation which gives England the excuse she has been seeking to annihilate us with a spurious appearance of justice on the pretext that she is helping France and maintaining the well-known Balance of Power in Europe, i.e. playing off all European States for her own benefit against us.\" In contrast, Lichnowsky outlined how the British foreign minister Sir Edward Grey had helped, with two treaties, on dividing the Portuguese Empire and establishing the Berlin–Baghdad railway, and had supported Germany's policy in the resolution of the Balkan Wars in 1912 and 1913 that excluded Russia. Britain had held back from declaring war until 4 August, after Belgium had been invaded, yet in a telegram sent to him from Berlin on 1 August: \"... England was already mentioned as an opponent...\" Lichnowsky summed up his view on blame for the outbreak of war, and the failure of diplomacy, in three main points: \"In view of the above, undeniable, facts, it is no wonder that the whole of the civilised world outside Germany places the entire responsibility for the world war upon our shoulders.\" At the pamphlet's end, he forecasts that the Central Powers were doomed to lose World War I, and says: \"The world will belong to the Anglo-Saxons, Russians and Japanese.\" The German role, he wrote, \"will be that of thought and commerce, not that of the bureaucrat and soldier.

The name Kéroualle was derived from an heiress whom an ancestor François de Penhoët had married in 1330. The Kérouaille family were nobles in Brittany, and their name was so spelt by themselves. The form \"Quérouaille\" was commonly used in England. All are derivations of the original Breton name Kerouazle, which is the most common form in Brittany.

Louis de Rouvroy, duc de Saint-Simon, asserts that her family threw her in the way of Louis XIV in the hope that she would become a royal mistress. In 1670, she accompanied Henrietta on a visit to Charles II at Dover. The sudden death of Henrietta left her unprovided for, but Charles II appointed her as a lady-in-waiting to his own queen, Catherine of Braganza. Unlike her predecessor Barbara Palmer, who had openly insulted the Queen, Louise was careful to show her every respect, and relations between the two women were never less than amicable. It was later said that Louise had been selected by the French court to fascinate Charles II, but for this there seems to be no evidence. Yet when there appeared a prospect that Charles would show her favour, the intrigue was vigorously pushed by the French ambassador, Colbert de Croissy, who was aided by the secretary of state Henry Bennet, 1st Earl of Arlington, and his wife. Louise, who concealed great cleverness and a strong will under an appearance of languor and a rather childlike beauty (diarist John Evelyn speaks of her \"baby face\"), yielded only when she had already established a strong hold on Charles' affections and character. Her son Charles (1672–1723) was created Duke of Richmond in 1675. The support Louise received from the French envoy was given on the understanding that she should serve the interests of her native sovereign. The bargain was confirmed by gifts and honours from Louis XIV and was loyally carried out by Louise. However, she was much disliked by the people in England. Louis gave her a pair of earrings worth the astonishing sum of eighteen thousand pounds, his most expensive gift to England that year and certainly more lavish than anything he had ever given Charles' queen. However, the hatred openly avowed for her in England was due as much to her own activity in the interest of France as to her notorious promiscuity. Nell Gwynne, another of Charles' mistresses, called her \"Squintabella\", and when mistaken for her, replied, \"Pray good people be civil, I am the \"Protestant\" whore.\" The titles of Baroness Petersfield, Countess of Fareham and Duchess of Portsmouth were granted to her for life on 19 August 1673. Her pensions and money allowances of various kinds were enormous. In 1681 alone she received £136,000. The French court gave her frequent presents, and in December 1673 conferred upon her the title \"Duchess of Aubigny\" in the Peerage of France at the request of Charles II. At about this time Louise was instrumental in bringing to Charles II's attention a young Frenchman who proposed a solution to the longitude problem. While the Frenchman's proposal was ineffective, it led Charles to establish the Royal Observatory, Greenwich, and appoint John Flamsteed as Astronomer Royal. Louise's thorough understanding of Charles' character enabled her to retain her hold on him to the end. She contrived to escape uninjured during the crisis of the \"Popish Plot\" in 1678: she found an unexpected ally in Queen Catherine, who was grateful for the kindness and consideration which Louise had always shown her. She was strong enough to maintain her position during a long illness in 1677 and in spite of a visit to France in 1682. One of Charles' nicknames for her was 'Fubbs', meaning plump or chubby. This female form was much in vogue at the time, and in 1682 the royal yacht HMY \"Fubbs\" – in reference to Louise's nickname – was built. In February 1685, she assisted in measures to see that Charles II was received into the Catholic Church on his deathbed.

The new fighter was to have also a better performance than the experimental Mitsubishi Ki-18. The results were the Nakajima Ki-27, the Kawasaki Ki-28, and the Mitsubishi Ki-33 (a modification of the Mitsubishi A5M carrier-based fighter). The Nakajima design was based on its earlier Ki-11 monoplane fighter which lost to the Ki-10 in the Type 95 Fighter competition. When the follow-up Nakajima Ki-12 proposal with a liquid-cooled engine and retractable landing gear was deemed too complex by the Japanese officials, the Ki-27 was designed by Koyama Yasushi to have an air-cooled radial engine and fixed landing gear. The aircraft had the Nakajima trademark wing with a straight leading edge and tapered trailing edge which would reappear again on the Ki-43, Ki-44, and Ki-84. The Ki-27 made its first flight on 15 October 1936. Although it had a slower top speed and worse climb performance than its competitors, the Army chose the Nakajima design for its outstanding turning ability granted by its remarkably low wing loading. The Army ordered 10 pre-production samples (Ki-27a) for further testing, which featured an enclosed cockpit with sliding canopy and larger wings. The type was officially accepted into service in 1937 as the Army Type 97 Fighter. In addition to Nakajima, the Ki-27 was also manufactured by Tachikawa Aircraft Company Ltd and Manshukoku Hikoki Seizo KK, with a total of 3,368 built before production ended in 1942.", "section_level": 1}, {"title": "Operational history.", "content": "The Ki-27 was the Imperial Japanese Army Air Force's main fighter until the start of World War II. When placed into combat service over northern China in March 1938, the Ki-27 enjoyed air superiority until the introduction of the faster Soviet-built Polikarpov I-16 fighters by the Chinese. In the 1939 Battle of Khalkhin Gol against the USSR in Mongolia, the Ki-27 faced both Polikarpov I-15 biplane and Polikarpov I-16 monoplane fighters. In the initial phase of the conflict, its performance was a match for the early model I-16s, and was considerably superior to the I-15 biplane. With better trained Ki-27 pilots, the IJAAF gained aerial superiority. The Ki-27 was armed with two 7.7 mm (.303 in) Type 89 machine guns and as with most aircraft of the period, lacked armor protection for the pilot and self-sealing or fire suppression in the fuel tanks. Later, the Soviet Air Force received improved I-16s. The faster, more heavily armed (with twin wing-mounted 20mm ShVAK cannons) and armored I-16 now nullified the Ki-27's advantages and it could now escape from the Ki-27 in a dive. The VVS introduced new tactics consisting of flying in large tightly knit formations, attacking with altitude and/or speed advantage and hit-and-run (high-energy) tactics much as Claire Chennault would later formulate for the 1941-era Flying Tigers (likewise to fly against Japanese forces). Japanese losses mounted but despite this they claimed 1,340 aircraft (six times the admitted Soviet losses and three times as many as Soviet aircraft admitted to being in the theatre). Japanese losses numbered 120 (including Ki-10s) while the Russians claimed 215 vs. a peak Japanese strength of 200 fighters. (Overclaiming remained commonplace through World War Two, despite gun cameras and expert intelligence assessments.) Top scoring pilot of the incident and top scoring IJAAF pilot on the Ki-27 and overall World War II IJAAF ace was Warrant Officer Hiromichi Shinohara, who claimed 58 Soviet planes (including an IJAAF record of 11 in one day) whilst flying Ki-27s, only to be shot down himself by a number of I-16s on 27 August 1939. The preference of Japanese fighter pilots for the Ki-27's high rate of turn caused the Army to focus excessively on manoeuvrability, a decision which later handicapped the development of faster and more heavily armed fighters. The Ki-27 served until the beginning of World War II in the Pacific, escorting bombers attacking Malaya, Singapore, Netherlands East Indies, Burma and the Philippines (where it initially fared poorly against the Brewster F2A Buffalo). The type also saw extensive action against the American Volunteer Group in the early months of the war. Soon outclassed by the American Curtiss P-40 Warhawks, the Ki-27 was replaced in front line service by the Nakajima Ki-43, while surviving examples continued to serve as a trainer. The Ki-27 was also exported for use with Manchukuo and Thai armed forces, seeing combat with both. In Thai service, Ki-27s reportedly damaged two North American P-51 Mustangs and shot down one Lockheed P-38 Lightning. In the final months of the war, desperate lack of aircraft forced the Japanese to utilize all available machines and the Ki-27 and 79 were no exception. Some were equipped with up to of explosives for \"kamikaze\" attacks, but some were redeployed as fighters, suffering terrible losses as on 16 February 1945 when the 39th Educational Flight Regiment scrambled 16 Ki-79 trainers from Yokoshiba Airfield to oppose a massive air raid from U.S. Task Force 58 carrier group, losing six aircraft with more damaged and five pilots killed, in return damaging at least one Hellcat and possibly downing a second.", "section_level": 1}, {"title": "Variants.", "content": "Data from", "section_level": 1}, {"title": "Surviving aircraft.", "content": "Two aircraft survive today:", "section_level": 1}], "src_summary": "The was the main fighter aircraft used by the Imperial Japanese Army Air Force up until 1940.

In 2000, he made his directorial debut, with the German television production \"Wenn man sich traut\". Before coming to the attention of a larger audience in Tarantino's \"Inglourious Basterds\", he had played Dr. Hans-Joachim Dorfmann in the British TV series \"The Gravy Train\" in 1990. The show is a story of intrigue and misdeeds set in the offices of the European Union in Brussels. In Quentin Tarantino's 2009 film \"Inglourious Basterds\", Waltz portrayed SS-Standartenführer Hans Landa, also known as \"The Jew Hunter\". Clever, courteous, multilingual—but also self-serving, cunning, implacable and murderous—the character of Landa was such that Tarantino feared he \"might have written a part that was un-playable\". Waltz received the Best Actor Award for the performance at the 2009 Cannes Film Festival and received acclaim from critics and the public. In 2009, he began sweeping critics' awards circuits, receiving awards for Best Supporting Actor from the New York Film Critics Circle, the Boston Society of Film Critics, Los Angeles Film Critics Association, and for Best Supporting Actor at the 67th Golden Globe Awards and the 16th Screen Actors Guild Awards in January 2010. The following month, he won the BAFTA for Best Supporting Actor, and won the Academy Award for Best Supporting Actor.

The concept of metta (loving kindness), based on Bhuddist teachings, is an integral part of this practice. Well known practitioners also emphasize meditation and devotion on part of the practitioner as integral to the effectiveness of this practice. The recipient wears loose, comfortable clothing and lies on a mat or firm mattress on the floor. In Thailand, a dozen or so subjects may be receiving massage simultaneously in one large room. The true ancient style of the massage requires that the massage be performed solo with just the giver and receiver. The receiver will be positioned in a variety of yoga-like positions during the course of the massage, that is also combined with deep static and rhythmic pressures. The massage generally follows designated lines (\"sen\") in the body. The legs and feet of the giver can be used to position the body or limbs of the recipient. In other positions, hands fix the body, while the feet do the massaging. A full Thai massage session may last two hours and includes rhythmic pressing and stretching of the entire body. This may include pulling fingers, toes, ears, cracking knuckles, walking on the recipient's back, and moving the recipient's body into many different positions.

In fact, the history of Thai massage is more complex than this legend of a single founder would suggest. Thai massage, like Thai traditional medicine (TTM) more generally, is a combination of influences from Indian, Chinese, Southeast Asian cultural spheres, and traditions of medicine, and the art as it is practiced today is likely to be the product of a 19th-century synthesis of various healing traditions from all over the kingdom.

His \"Eastern\" influences are clearly audible in all of these recordings, with spots for instruments like the rahab, shanai, arghul, koto and a collection of Chinese wooden flutes and bells along with his tenor and flute. Even his use of the western oboe sounds exotic in this context; it is not a standard jazz instrument. Indeed, the tunes themselves are a mixture of jazz standards, blues and film music usually performed with a piano/bass/drums rhythm section in support. Lateef made numerous contributions to other people's albums including his time as a member of saxophonist Cannonball Adderley's Quintet during 1962–64. In the late 1960s he began to incorporate contemporary soul and gospel phrasing into his music, still with a strong blues underlay, on albums such as \"Detroit\" and \"Hush'n'Thunder\". Lateef expressed a dislike of the terms \"jazz\" and \"jazz musician\" as musical generalizations. As is so often the case with such generalizations, the use of these terms do understate the breadth of his sound. For example, in the 1980s, Lateef experimented with new-age and spiritual elements. In 1960, Lateef again returned to school, studying flute at the Manhattan School of Music in New York City.

In the 6th century BC, about 250 years prior to the establishment of the Ptolemaic dynasty, the Greek philosopher Thales is recorded as using similar triangles to estimate the height of the pyramids of ancient Egypt. He measured the length of the pyramids' shadows and that of his own at the same moment, and compared the ratios to his height (intercept theorem). Thales also estimated the distances to ships at sea as seen from a clifftop by measuring the horizontal distance traversed by the line-of-sight for a known fall, and scaling up to the height of the whole cliff. Such techniques would have been familiar to the ancient Egyptians. Problem 57 of the Rhind papyrus, a thousand years earlier, defines the \"seqt\" or \"seked\" as the ratio of the run to the rise of a slope, \"i.e.\" the reciprocal of gradients as measured today. The slopes and angles were measured using a sighting rod that the Greeks called a \"dioptra\", the forerunner of the Arabic alidade. A detailed contemporary collection of constructions for the determination of lengths from a distance using this instrument is known, the \"Dioptra\" of Hero of Alexandria (c. 10–70 AD), which survived in Arabic translation; but the knowledge became lost in Europe until in 1615 Snellius, after the work of Eratosthenes, reworked the technique for an attempt to measure the circumference of the earth. In China, Pei Xiu (224–271) identified \"measuring right angles and acute angles\" as the fifth of his six principles for accurate map-making, necessary to accurately establish distances, while Liu Hui (c. 263) gives a version of the calculation above, for measuring perpendicular distances to inaccessible places.", "section_level": 1}], "src_summary": "In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to it from known points.

In March, Spyker announced a sponsor deal with Etihad Airways and Aldar Properties, two companies from Abu Dhabi, United Arab Emirates. The official name of the entrant during the season was Etihad Aldar Spyker F1 Team. On 10 July, Albers was released from his Spyker contract, due to a lack of sponsorship money, which would have compromised the team's development programme. Mol described it as \"one of the toughest decisions of my career\". Despite former Red Bull Racing driver Christian Klien testing for the team on 12 July 2007, Albers' replacement for the 2007 European Grand Prix was Winkelhock. During the 2007 European Grand Prix, Winkelhock became the only driver to lead a Grand Prix in a Spyker, due to the team's tyre selection. However, Winkelhock did not keep his race drive as this went to Sakon Yamamoto. In August, the new B-Spec Spyker model, which the team hoped to use at the 2007 Turkish Grand Prix, failed the crucial rear crash test which is set by the FIA. All cars must pass these tests to be allowed to race. However, a few days later it was confirmed that the car had passed the crash test in time to compete in the Italian Grand Prix. On 30 September at the 2007 Japanese Grand Prix, the team scored its first and only championship point. Driver Sutil finished 9th on the track, but was promoted to 8th place and into the points scoring positions when stewards ruled post-race that Toro Rosso's Vitantonio Liuzzi had overtaken Sutil under a yellow flag on lap 55; Liuzzi was subsequently given a 25-second penalty that dropped his time below Sutil's. On 14 August, Spyker Cars announced that it might need to sell all or part of the team due to a potential split of the team from its parent company. The team was sold to a consortium named \"Orange India\" led by Indian businessman Vijay Mallya and Dutch entrepreneur (and existing board member) Michiel Mol after approval by Spyker's shareholders.

She was an excellent shot and attended shooting matches, participated in hunting while she and her ladies-in-waiting dressed in amazon attire and also played billiards. Elisabeth Christine was later rumored to be a crypto-Protestant, likely because she was a patron of Jansenists such as Johann Christoph Bartenstein. Charles VI did not allow her any political influence whatsoever after her arrival in Austria in 1713. However, she was described as intelligent and self-sufficient, and she established political connections among the ministers, especially Starhemberg, and she took some initiative to engage in politics on her own. In the 1720s, she appeared to have had some influence in the treaty with the Russian Tsar through her family connections in Northern Germany, and she allied herself with the court faction which opposed the plans to marry her daughters to members of the Spanish royal house. The marriage of Elisabeth Christine was dominated by the pressure upon her to give birth to a male heir. This she later fulfilled when she gave birth to a male heir named Archduke Leopold John in 1716. However, at age 7 months the infant Leopold died. She reportedly found the situation very stressing and was tormented by the loss of confidence in Charles VI that this caused. Three years after her marriage, court doctors prescribed large doses of liquor to make her more fertile, which gave her face a permanent blush. During her 1725 pregnancy, Charles unsuccessfully had her bedchamber decorated with erotic images of male beauty so as to make her expected baby male by stimulating her fantasy. After this, the court doctors prescribed a rich diet to increase her fertility, which made her so fat that she became unable to walk, experienced breathing problems, insomnia and dropsy and had to be lowered into her chairs by a specially constructed machine. Though her health was devastated by the different prescriptions as how to make her conceive another son, Charles VI apparently did care for her: he continued to refer to her by her pet name White Liz, expressed sincere concern in his diary about her health and left her an independent income in his will. Charles had a mistress before the marriage, and he had a mistress, countess Althann, from 1711 onward, though Althann was not an official mistress and had been married to one of his ministers shortly before the arrival of the empress to make the relationship more discreet.

Fiat had decided to produce a new coupé based upon the Tipo platform when the Pininfarina factory was suddenly dormant after the Cadillac Allante project failed around 1990. Two designs were put forward, with Fiat's in-house Centro Stile team competing with Pininfarina.The concept as put forward by Centro Stile's Chris Bangle unexpectedly won the Fiat management over. The design previously offered by Pininfarina was eventually accepted by Peugeot, who adopted it as the 406 Coupe in October 1996. On its launch in January 1994, the Coupé was available with a four cylinder, 2.0 L 16V engine, in both turbo (190 PS) and normally aspirated (139 PS) versions. Both engines were later versions of Fiat's twin-cam design and inherited from the Lancia Delta Integrale, winner of the World Rally Championship a record six times. 1996 brought in a 1.8 L 16V engine (not available in the United Kingdom, 131 PS), along with a 2.0 litre five cylinder 20V (147 PS), and a five cylinder 2.0 litre 20V turbo (220 PS). Along with the new engines Fiat also made some minor design changes including the front grill, steering wheel,the door panel now included leather, the interior centre console was redesigned and the digital clock was replaced with an analog one. Production of the right-hand drive models for markets including the UK began in early 1995, and continued until the end of Coupe production five years later. Both the turbocharged 16v/4-cylinder and 20v/5-cylinder (4v per cyl.) versions were equipped with a very efficient \"Viscodrive\" limited-slip differential to counter the understeer that plagues most powerful front wheel drive cars. Additionally, the Coupé featured independent suspension all round: at the front MacPherson struts and lower wishbones anchored to an auxiliary crossbeam, offset coil springs and anti roll bar; at the rear, trailing arms mounted on an auxiliary subframe, coil springs and an anti roll bar. 1998 saw the release of the Limited Edition which could be identified externally by a body kit, titanium grey details such as the wheels, fuel cap, rear light cups, mirror casings and the Brembo brake calipers at the front were now painted red. Inside, the Limited Edition specification included a push-button start, Recaro seats with red leather inserts, Sparco pedals and the recognisable body-coloured dash was replaced with a titanium grey example. Mechanically, there were few changes over a standard 20V Turbo model, but the LE (as they came to be known) did add a six speed gearbox for the first time, strut brace and the engine covers were all painted red. The LE was produced in Black (flat), Red (flat), Vinci Grey (metallic), Crono Grey (flat) and Steel Grey (metallic). Each Limited Edition ('LE') Coupé was manufactured with a badge located by the rear view mirror which contained that car's unique number (it is rumoured that Michael Schumacher was the original owner of LE No. 0001, however when the question was raised to him personally he confirmed he had owned one, but a red one, while LE No. 0001 is a Crono Grey one). Originally, a spokesman from Fiat stated only approximately 300 Limited Editions would be built (although the plaques always allowed for four-figure numbers). The final amount was much higher, with numbers as high as 1400 touted by some. This angered many of the owners of the original 300 cars and almost certainly impacted residual values. The original number however was quoted by a spokesman for Fiat UK, so probably that number only applied to the United Kingdom. In 1998, the 2.0 litre five cylinder 20V got a Variable Inlet System, which brought the power to. In addition, the sills of the Turbo version were colour matched with the body paintwork. Fiat also released the 2.0 litre five cylinder Turbo 'Plus'. This model came with an option kit that made it virtually identical to the LE, except for minor interior design changes and without the unique identification badge of the LE. In early 2000, Fiat released another special version of the Fiat Coupé. Featuring the 1.8 litre engine, it was only available throughout mainland Europe and marketed as an elegant and affordable edition. This final version had different leather seats, white speedo with yellow arrows, new 16 inch bbs rims and the new \"honeycomb\"grill. Production finished in the summer of that year, with no plans for a direct successor. Fiat also made changes throughout the rest of the range: new seats, side skirts, wheels for the 2.0 litre 20V model, 'Plus' edition wheels and a six speed transmission as standard on turbo models, and Fiat manufactured seats on the 'Plus' that were virtually identical to the original Plus Recaro seats with the addition of extra airbags. The 2.0 litre 20V Turbo model is capable of accelerating from 0–100 km/h (0 to 62 mph) in 6.5 seconds and 6.3 seconds for the 20v Turbo Plus, with a top speed of or with later six speed gearbox.

He used the time to become acquainted with the Imperial family, and wished to marry into the Habsburg dynasty for dynastic and economic reasons. They met a second time in 1718. However, Charles Albert initially asked to marry her elder sister Maria Josepha, but she was already engaged at the time of his proposal. Maria Amalia and her sister Maria Josepha were both given a very strict Catholic upbringing with focus on Catholic religious duties by their mother, but Maria Amalia was described as having a more vivid and extrovert personality than the more serious Maria Josepha.

In May 1727, at the birth of the heir, Maximilian III Joseph, Maria Amalia was given her own residence, the Fürstenried Palace as a puerperal gift; and in 1734, Charles Albert named the Amalienburg in the Nymphenburg Palace Park after her. Similar to her mother, she was forced to accept the infidelity of her spouse: her husband also had six illegitimate children.

During this time, Bennett attended some of the Darmstadt summer courses in 1955, where he was exposed to serialism. He later spent two years in Paris as a student of the prominent serialist Pierre Boulez between 1957 and 1959. He always used both his first names after finding another Richard Bennett active in music. Bennett taught at the Royal Academy of Music between 1963 and 1965, at the Peabody Institute in Baltimore, United States from 1970 to 1971, and was later International Chair of Composition at the Royal Academy of Music between 1994 and the year 2000. He was appointed a Commander of the Order of the British Empire (CBE) in 1977, and was knighted in 1998. Bennett produced over 200 works for the concert hall, and 50 scores for film and television. He was also a writer and performer of jazz songs for 50 years. Immersed in the techniques of the European avant-garde via his contact with Boulez, Bennett subsequently developed his own dramato-abstract style. In his later years, he adopted an increasingly tonal idiom. Bennett regularly performed as a jazz pianist, with such singers as Cleo Laine, Marion Montgomery (until her death in 2002), Mary Cleere Haran (until her death in 2011), and more recently with Claire Martin, performing the Great American Songbook. Bennett and Martin performed at such venues as The Oak Room at the Algonquin Hotel in New York, and The Pheasantry and Ronnie Scott's Jazz Club in London. In later years, in addition to his musical activities, Bennett became known as an artist working in the medium of collage. He exhibited these collages several times in England, including at the Holt Festival, Norfolk in 2011, and at the Swaledale Festival, Yorkshire, in 2012. The first ever exhibition of his collages was in London in 2010, at the South Kensington and Chelsea Mental Health Centre, curated by the Nightingale Project, a charity that takes music and art into hospitals. Bennett was a patron of this charity. Bennett is honoured with four photographic portraits in the collection of the National Portrait Gallery, London. Anthony Meredith's biography of Bennett was published in November 2010. Bennett is survived by his sister Meg (born 1930), the poet M. R.

Some writing found indicates the settlement is closely connected to the known Roman colony in modern-day Zenica, away. In the Middle Ages the Travnik area was known as the \" župa Lašva\" province of the medieval Bosnian Kingdom. The area is first mentioned by Bela IV of Hungary in 1244. Travnik itself was one of a number of fortified towns in the region, with its fortress \"Kaštel\" becoming today's old town sector. The city itself is first mentioned by the Ottomans during their conquest of nearby Jajce. After the Ottoman conquest of Bosnia in the 15th century, much of the local population converted to Islam. The city quickly grew into one of the more important settlements in the region, as authorities constructed mosques, marketplaces, and various infrastructure. During 1699 when Sarajevo was set afire by soldiers of Field-Marshal Prince Eugene of Savoy, Travnik became the capital of the Ottoman province of Bosnia and residence of the Bosnian viziers. The city became an important center of government in the whole Western frontier of the empire, and consulates were established by the governments of France and Austria-Hungary. The period of Austrian occupation brought westernization and industry to Travnik, but also a reduction of importance. While cities such as Banja Luka, Sarajevo, Tuzla, and Zenica grew rapidly, Travnik changed so little that during 1991 it had a mere 30,000 or so people, with 70,000 in the entire municipality. A large fire started by a spark from a locomotive in September 1903 destroyed most of the towns buildings and homes, leaving only some hamlets and the fortress untouched. The cleanup and rebuilding took several years. From 1929 to 1941, Travnik was part of the Drina Banovina of the Kingdom of Yugoslavia. During the Bosnian War, the town mostly escaped damage from conflict with Serbian forces, hosting refugees from nearby Jajce, but the area experienced fighting between local Bosniak and Croat factions before the Washington Agreement was signed in 1994.

The two campaigns are distinguishable by a slight shift in the axis of the work and by changes in stylistic handwriting. Under Bishop, an extra 4.9 m was added to the height, to make it the highest-vaulted cathedral in Europe. The vaulting in the interior of the choir reaches 48 m (157.48 feet) in height, far surpassing the concurrently constructed Cathedral of Notre-Dame in Amiens, with its nave. (A formerly often-quoted beginning date of 1247 was based on an error made by an early historian of Beauvais.) The work was interrupted in 1284 by the collapse of some of the vaulting of the recently completed choir. This collapse has been seen as a disaster that produced a failure of nerve among the French masons working in Gothic style. The collapse also marked the beginning of an age of smaller structures generally, which was associated with demographic decline, the Hundred Years' War, and with the thirteenth century. However, large-scale Gothic design continued, and the choir was rebuilt at the same height, albeit with more columns in the chevet and choir, converting the vaulting from quadripartite vaulting to sexpartite vaulting. The transept was built from 1500 to 1548. In 1573, the fall of the 153 m (502 feet) central tower stopped work again. The tower made the church the tallest structure in the world (1569–1573). Afterwards little structural addition was made. The choir has always been wholeheartedly admired, with Eugène Viollet-le-Duc calling the Beauvais choir \"the Parthenon of French Gothic.\" Its façades, especially that on the south, exhibit all the richness of the late Gothic style. The carved wooden doors of both the north and the south portals are masterpieces, respectively, of Gothic and Renaissance workmanship. The church possesses an elaborate astronomical clock in neo-Gothic taste (1866) and tapestries of the 15th and 17th centuries, but its chief artistic treasures are stained glass windows of the 13th, 14th, and 16th centuries, the most beautiful of them from the hand of Renaissance artist Engrand Le Prince, a native of Beauvais. To him also is due some of the stained glass in St-Etienne, the second church of the town, and an interesting example of the transition stage between the Gothic and the Renaissance styles.

Even though the structure was to be taller, the buttresses were made thinner in order to pass maximum light into the cathedral. In 1284, only twelve years after completion, part of the choir vault collapsed, along with a few flying buttresses. It is now believed that the collapse was caused by resonant vibrations due to high winds. The accompanying photograph shows lateral iron supports between the flying buttresses; it is not known when these external tie rods were installed. The technology would have been available at the time of the initial construction, but the extra support might not have been considered necessary until after the collapse in 1284, or even later. In the 1960s, the tie rods were removed; the thinking was that they were ungraceful and unnecessary. However, the oscillations created by the wind became amplified, and the choir partially disassociated itself from the transept. Subsequently, the tie rods were reinstalled, but this time with rods made of steel. Since steel is less ductile than iron, the structure became more rigid, possibly causing additional fissures. As the floor plan shows, the original design included a nave that was never built. Thus, the absence of shouldering support that would have otherwise been provided by the nave contributes to the structural weakness of the cathedral. With the passage of time, other problems surfaced, some requiring more drastic remedies. The north transept now has four large wood-and-steel lateral trusses at different heights, installed during the 1990s to keep the transept from collapsing (see photograph below). In addition, the main floor of the transept is interrupted by a much larger brace that rises out of the floor at a 45-degree angle. This brace was installed as an emergency measure to give additional support to the pillars that, until now, have held up the tallest vault in the world. These temporary measures will remain in place until more permanent solutions can be determined.

People who like to use chapels may find it peaceful and relaxing to be away from the stress of life, without other people moving around them. The word \"chapel\", like the associated word \"chaplain\", is ultimately derived from Latin. More specifically, the word \"chapel\" is derived from a relic of Saint Martin of Tours: traditional stories about Martin relate that while he was still a soldier, he cut his military cloak in half to give part to a beggar in need. The other half he wore over his shoulders as a \"small cape\" (). The beggar, the stories claim, was Christ in disguise, and Martin experienced a conversion of heart, becoming first a monk, then abbot, then bishop. This cape came into the possession of the Frankish kings, and they kept the relic with them as they did battle. The tent which kept the cape was called the \"capella\" and the priests who said daily Mass in the tent were known as the \"capellani\". From these words, via Old French, we get the names \"chapel\" and \"chaplain\". The word also appears in the Irish language in the Middle Ages, as Welsh people came with the Norman and Old English invaders to the island of Ireland. While the traditional Irish word for church was \"eaglais\" (derived from \"ecclesia\"), a new word, \"séipéal\" (from \"cappella\"), came into usage. In British history, \"chapel\" or \"meeting house\" were formerly the standard designations for church buildings belonging to independent or Nonconformist religious societies and their members. They were particularly associated with the pre-eminence of independent religious practice in rural regions of England and Wales, the northern industrial towns of the late 18th and 19th centuries, and centres of population close to but outside the City of London.

Frequently they were established by evangelical philanthropists with a vision of spreading Christianity in cities whose needs could no longer be met by the parishes. Some functioned more privately, with a wealthy person building a chapel so that they could invite their favorite preachers. They are anomalies in the English ecclesiastical law, having no parish area, but being permitted to have an Anglican clergyman licensed there. Historically many Anglican churches were proprietary chapels. Over the years they have often been converted into normal parishes.

Chapels can also be found for worship in Judaism. The word \"chapel\" is in particularly common usage in the United Kingdom, and especially in Wales, for Nonconformist places of worship; and in Scotland and Ireland for Roman Catholic churches. In the UK, due to the rise in Nonconformist chapels during the late 18th and early 19th centuries, by the time of the 1851 census, more people attended the independent chapels than attended the state religion's Anglican churches. In Roman Catholic Church canon law, a chapel, technically called an \"oratory\", is a building or part thereof dedicated to the celebration of services, particularly the Mass, which is not a parish church. This may be a private chapel, for the use of one person or a select group (a bishop's private chapel, or the chapel of a convent, for instance); a semi-public oratory, which is partially available to the general public (a seminary chapel that welcomes visitors to services, for instance); or a public oratory (for instance, a hospital or university chapel).

As a result of Pulu seizing the throne in a bloody \"coup d'état\", the old royal family was slaughtered, and the new monarch set Assyria on the path to expand the empire in order to ensure the survival of the kingdom. A mutilated brick inscription states that he is the son of Adad-nirari (III); however, the Assyrian King List makes Tiglath-pileser (III) the son of Ahur-nirari (V), son of Adad-nirari (III). This is quite a discrepancy for the King list places Adad-nirari III four monarchs before Tiglath-pileser's reign and depicts Ashur-nirari (V) as both his father and immediate predecessor upon the throne.

Ashur-nirari (V) is also said to be a son of Adad-nirari (III), implying brotherhood with Shalmaneser III (IV), and Ashur-dan III (III). The Assyrian records contain very little information concerning Adad-nirari (III) and nothing about Shalmaneser III (IV) or Ashur-dan III (III). Significantly, an alabaster stele was discovered in 1894 at Tell Abta displaying the name Tiglath-pileser imprinted over that of Shalmaneser (IV), a successor of Adad-Nirari (III) and the third sovereign prior to Tiglath-pileser (III).

A surgical mask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes, or certain medical procedures. Surgical masks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the face mask and the face. A surgical mask is not to be confused with a respirator and is not certified as such. Surgical masks are not designed to protect the wearer from inhaling airborne bacteria or virus particles and are less effective than respirators, which are designed for this purpose.

The boy became ill when he was only one month old, and his mother prayed to St. Francis and promised that her son would spend a year in a Franciscan friary if he were healed. Her prayer was granted, and at 13 years of age Francis fulfilled that votive year. After this year he dedicated himself to a life of solitude and penance as a hermit. In 1435, two followers joined Francis and began the community, which was first called the \"Poor Hermits of St. Francis of Assisi.\" Francis and his followers founded hermitages at Paterno in 1444 and Milazzo, Sicily, in 1469. The Archbishop of Cosenza approved the group and established them as a religious order on November 30, 1470, and this approval was confirmed by Pope Sixtus IV in his bull \"Sedes Apostolica\" of May 17, 1474. At that time, the pope also changed their status from that of hermits to mendicant friars. The name \"Minims\" comes from the Italian word \"minimo\", meaning the smallest or the least, and their founder would call himself \"il minimo dei minimi\". Francis of Paola wanted to distinguish himself as being of even less significance than the Friars Minor founded by his patron saint. Francis composed a rule for the community in 1493, which was approved under the name of \"Hermits of the Order of the Minims\". The definitive version of the rule was solemnly approved by Pope Julius II in the Bull \"Inter ceteros\", July 28, 1506, who also simplified the name of the community to the Order of Minims (). In addition to the standard three religious vows of chastity, poverty and obedience, the rule contains the vow of \"a Lenten way of life\" (), which is considered to be the distinctive feature of the Minims. This vow is for perpetual abstinence from all meat and dairy products, veganism, except in case of grave illness and by order of a physician. Because of asceticism, The Order is also discalced in character and there are other acts of humility. The Minim habit consists of a black wool tunic, with broad sleeves, a hood, and a short scapular. It has a thick, black cord (with four knots that signify the four vows) with a tassel to gird the robe. The Order of the Minims spread throughout Italy in the fifteenth century and was introduced to France in 1482, and later to Spain and to Germany in 1497. The houses in Spain, Germany, and France were suppressed during the period following the French Revolution. By the turn of the 20th century, only 19 friaries remained, all but one of them in Italy.

Through the ambassador, they communicated their interest to the saint, and asked for a rule of life which they might follow.

During the Nazi occupation of Poland, he founded the Independent Theatre, and served as a professor at the Academy of Fine Arts in Kraków as well as a director of experimental theatre in Kraków from 1942 to 1944. After the war, he became known for his avant-garde work in stage design including designs for \"Saint Joan\" (1956) and \"Measure for Measure\" (1956). Specific examples of such changes to standard theatre were stages that extended out into the audience, and the use of mannequins as real-life actors. In 1955, with a group of visual artists disenchanted with the growing institutionalization of avant-garde, he formed a new theatre ensemble called Cricot 2. In the 1960s, Cricot 2 gave performances in many theatres in Poland and abroad, gaining recognition for their stage \"happenings\". His interest was mainly with the absurdists and Polish writer and playwright Stanisław Ignacy Witkiewicz (also known as \"Witkacy\"). Stage productions of Witkacy's plays \"The Cuttlefish\" (1956) and \"The Water Hen\" (1969) were regarded as his best achievements during this time. A 1972 performance of \"The Water Hen\" was described as \"the least-publicised, most talked-about event at the Edinburgh festival\". \"Dead Class\" (1975) was the most famous of his theatre pieces of the 1970s. A TV-Movie of the production was made in 1977, directed by Andrzej Wajda. In the play, Kantor himself played the role of a teacher who presided over a class of apparently dead characters who are confronted by mannequins representing the characters' younger selves. He had begun experimenting with the juxtaposition of mannequins and live actors in the 1950s. His later works of the 1980s were very personal reflections. As in \"Dead Class\", he would sometimes represent himself on stage. In the 1990s, his works became well known in the United States due to presentations at Ellen Stewart's La MaMa Experimental Theatre Club which inspired Lower East Side cultural leaders such as the Nuyorican poet Giannina Braschi.

In 1816, he moved to Geneva, where he attended lectures by M. A. Pictet in physics, C. G. de la Rive in chemistry, and A. P. de Candolle in botany, and before he had reached his majority, he was engaged with Pierre Prévost in original work on problems of physiological chemistry and even of embryology. In 1822, he moved to Paris, acting on the advice of Alexander von Humboldt, where he became professor of chemistry, initially at the Lyceum, later (1835) at the École polytechnique. He was one of the founders of the École centrale des arts et manufactures (later named École centrale Paris) in 1829. In 1832 Dumas became a member of the French Academy of Sciences. From 1868 until his death in 1884 he would serve the academy as the permanent secretary for its department of Physical Sciences. In 1838, Dumas was elected a foreign member of the Royal Swedish Academy of Sciences. The same year he became correspondent of the Royal Institute of the Netherlands and, when that became the Royal Netherlands Academy of Arts and Sciences in 1851, he joined as a foreign member. Dumas was president of Société d'encouragement pour l'industrie nationale from 1845 to 1864. After 1848, he exchanged much of his scientific work for ministerial posts under Napoléon III. He became a member of the National Legislative Assembly. He acted as minister of agriculture and commerce for a few months in 1850–1851, and subsequently became a senator, president of the municipal council of Paris, and master of the French mint, but his official career came to a sudden end with the fall of the Second Empire. Dumas was a devout Catholic who would often defend Christian views against critics. Dumas died at Cannes in 1884, and is buried at the Montparnasse Cemetery in Paris, in a large tomb near the back wall. His is one of the 72 names inscribed on the Eiffel tower.", "section_level": 1}, {"title": "Scientific work.", "content": "Dumas was one of the first to criticise the electro-chemical doctrines of Jöns Jakob Berzelius, which, at the time his work began, were widely accepted as the true theory of the constitution of compound bodies, and opposed a unitary view to the dualistic conception of the Swedish chemist. In a paper on the atomic theory, published in 1826, he anticipated to a remarkable extent some ideas which are frequently supposed to belong to a later period; and the continuation of these studies led him to the ideas about substitution (metalepsis) which were developed about 1839 into the theory (Older Style Theory) that in organic chemistry there are certain types which remain unchanged even when their hydrogen is replaced by an equivalent quantity of a halide element. The classification of organic compounds into homologous series was advanced as one consequence of his researches into the acids generated by the oxidation of the alcohols. Dumas also showed that kidneys remove urea from the blood. Vapour densities and atomic masses Dumas perfected the method of measuring vapor densities which was also important in determining atomic weights (see below). A known amount of the substance being analyzed was put into a previously weighed glass bulb, which was then sealed and heated in water to vaporize the substance. The pressure was recorded with a barometer, and the bulb is allowed to cool to determine the mass of the vapor. The universal gas law was then used to determine the moles of gas within the bulb. In an 1826 paper, he described his method for ascertaining vapour densities, and the redeterminations which he undertook by its aid of the atomic weights of carbon and oxygen proved the forerunners of a long series which included some thirty of the elements, the results being mostly published in 1858–1860. He showed \"in all elastic fluids observed under the same conditions, the molecules are placed at equal distances\". He also determined the atomic weight of titanium, one of the rare earth elements. Dumas established new values for the atomic mass of thirty elements, setting the value for hydrogen to 1. Determination of nitrogen In 1833, Dumas developed a method for estimating the amount of nitrogen in an organic compound, founding modern analysis methods. He made important revisions to the existing combustion methods with a sophisticated pneumatic trough. These revisions were the flushing of the combustion tube with carbon dioxide and the addition of potassium hydroxide in the pneumatic trough. Flushing with carbon dioxide eliminated the nitrogen present in the air that previously occupied the combustion tube, eliminating the need for correction due to nitrogen in the air. The potassium hydroxide dissolved the passing carbon dioxide gas, which left nitrogen as the only gas in the collection tube. Theory of substitution and theory of chemical types At the Tuileries palace in Paris, guests of a soiree began reacting adversely to a gas suddenly emitted by the candles. Alexandre Brongniart asked his son-in-law, Dumas, to investigate. Dumas found that the coughing and dangerous fumes were caused by chlorine present in the candle wax. Chlorine had been used to whiten the candles, and Dumas concluded that it must have combined during the candle-making process. This led Dumas to investigate the behavior of chlorine substitution in other chemical compounds. One of the most important research projects of Dumas was that on the action of chlorine on acetic acid to form trichloroacetic acid – a derivative of essentially the same character as the acetic acid itself. Dumas extended this to a theory (sometimes considered a law) which states that in an organic compound, a hydrogen atom may be substituted for any halogen. In his published paper on the subject, Dumas introduces his theory of types. Since the trichloracetic acid retained similar properties to acetic acid, Dumas reasoned that there were certain chemical structures that remained comparatively unchanged even if one atom were changed within them. The basis of this theory rests in the natural history of organism classification, which Dumas learned under the botanist de Candolle. This new theory challenged Berzelius's previous theory of electrochemical dualism and was also a competitor of radical theory.", "section_level": 1}, {"title": "Family.", "content": "He married Herminie Brongniart, daughter of Alexandre Brongniart, in 1826.", "section_level": 1}], "src_summary": "Jean Baptiste André Dumas (14 July 180010 April 1884) was a French chemist, best known for his works on organic analysis and synthesis, as well as the determination of atomic weights (relative atomic masses) and molecular weights by measuring vapor densities.

Founded in Břevnov atop earlier social democratic initiatives, such as the Ouls, it represented much of the Kingdom of Bohemia in the Austrian parliament, and its significant role in the political life of the empire was one of the factors that led to the creation of an independent Czechoslovakia. After the collapse of Austria-Hungary at the end of the First World War, the party became one of the leading parties of the first Czechoslovak Republic. Its members were split over whether to join the Comintern, which in 1921 resulted in the fracturing of the party, with a large part of its membership then forming the new Communist Party of Czechoslovakia. During the occupation of Czechoslovakia by Nazi Germany, the party was officially abolished, but its members organized resistance movements contrary to the laws of the German-controlled Protectorate of Bohemia and Moravia, both at home and abroad. After the re-establishment of the Czechoslovak Republic in 1945, the party returned to its pre-war structure and became a member of the National Front which formed a new governing coalition. In 1948, after the Communist Party of Czechoslovakia gained a parliamentary majority, the Czech Social Democratic Party was incorporated into the Communist Party. At the time of the Prague Spring, a reformist movement in 1968, there were talks about allowing the recreation of a Social Democratic party, but Soviet intervention put an end to such ideas. It was only after the Velvet Revolution of 1989 that the party was recreated. Since the dissolution of Czechoslovakia, which came into effect on 1 January 1993, the ČSSD has been one of the major political parties of the Czech Republic, and until October 2017 was always one of the two parties with the largest number of seats in the Chamber of Deputies. At the 1998 parliamentary election, the party won the largest number of seats but failed to form a coalition government, so formed a minority government under its leader Miloš Zeman. With only 74 seats out of 200, the government had confidence and supply from the Civic Democratic Party (ODS), under the so-called Opposition Agreement. At the elections of 2002, the party gained 70 of the 200 seats in the of Deputies of the Czech Republic Chamber of Deputies. Its leader Vladimír Špidla became prime minister, heading a coalition with two small centre-right parties, the Christian and Democratic Union – Czechoslovak People's Party (KDU–ČSL) and the Freedom Union – Democratic Union (US-DEU) until he was forced to resign in 2004 after the ČSSD lost in the European Parliament elections of 2004 The next leader was Stanislav Gross, serving as leader from 26 June 2004 to 26 April 2005 and as prime minister from 4 August 2004 to 25 April 2005. He resigned after a scandal when he was unable to explain the source of money used to buy his house. The successor of Gross as prime minister was Jiří Paroubek, while Bohuslav Sobotka became acting party leader from 26 April 2005 to 13 May 2006. Paroubek was then elected as the new party leader in the run-up to the June 2006 elections, at which the party won 32.3% of the vote and 74 out of 200 seats. The election at first caused a stalemate, since the centre-right parties plus the Green Party and the centre-left parties each had exactly 100 seats. The stalemate was broken when two ČSSD deputies, Miloš Melčák and Michal Pohanka, abstained during a vote of confidence, allowing a coalition of the Civic Democrats (ODS), the KDU-ČSL, and the Green Party to form a government. Hence the ČSSD went into opposition. At the 2010 legislative elections on 28 and 29 May, the ČSSD gained 22.08% of the vote but remained the largest party, with 56 seats. Failing to form a governing coalition, it remained in opposition to a government coalition of the ODS, conservative TOP 09 and conservative-liberal Public Affairs parties. Paroubek resigned as leader on 7 June and was succeeded by Sobotka. The Party remained the largest Party even after the 2013 legislative election of 25 and 26 October 2013 and in December formed a governing coalition with the populist ANO 2011 and the centrist Christian and Democratic Union – Czechoslovak People's Party. The leader of ČSSD, Bohuslav Sobotka, became the new Prime Minister of the Czech Republic. The party suffered heavy losses in the 2017 legislative election and was reduced to only 15 seats, the worst result in its history.

He set up his photographic studio at first as a hobby and was exhibiting his work internationally by 1893 (London), including Cairo (1897), Berlin (1898–99, including a solo exhibition), Philadelphia (1902), Budapest & Marseilles (1903), Nice (1903 & 1905), Riga (1905), Dresden (1909) and Rome (World Fair 1911). His well-known study of two young boys clinging to an Ionic column was published in \"The Studio\" (London) in June 1893 (above a nude study by Baron Corvo of Cecil Castle, cousin of Charles Kains Jackson), which brought his work to the notice of a wider public. In 1895, when his family's fortune was lost through the \"Hammerstein affair\", Gloeden received as a gift from his friend and patron the Grand Duke of Mecklenburg-Schwerin, a large-format plate camera. Soon his work brought him visitors from Europe, including royalty, industrialists, writers, including Oscar Wilde in December 1897, and artists. In 1930, Gloeden ceased work as a photographer and sold his house on the Piazza San Domenico in Taormina in return for an annuity and residence rights.

Semenov was a Transbaikalian Cossack – dark and thickset, and of the rather alert Mongolian type. His intelligence was of a specifically Cossack calibre, and he was an exemplary soldier, especially courageous when under the eye of his superior.

The White Siberian Provisional Government appointed Semyonov commander of a detached unit with headquarters in Chita. Initially Adm. Aleksandr Kolchak refused to recognize Semyonov's authority, but he had no choice and had to accept Semyonov as de facto leader and confirm him as Commander-in-Chief of the Chita military district.

The region under his control, also called Eastern Okraina, extended from Verkhne-Udinsk near Lake Baikal to the Shilka River and the town of Stretensk, to Manzhouli, where the Chinese Eastern Railway met the Chita Railway, and northeast some distance along the Amur Railway. Semyonov handed out copies of the \"Protocols of the Elders of Zion\" to the Japanese troops he became associated with. After the fall of Kolchak's Siberian government, the admiral transferred power to Semyonov in the Far East. However, Semyonov was unable to keep his forces in Siberia under control: they stole, burned, murdered and raped, and developed a reputation for being little better than thugs.

It is the retinal molecule that changes its conformation when absorbing a photon, resulting in a conformational change of the surrounding protein and the proton pumping action. It is covalently linked to Lys216 in the chromophore by Schiff base action. After photoisomerization of the retinal molecule, Asp85 becomes a proton acceptor of the donor proton from the retinal molecule. This releases a proton from a \"holding site\" into the extracellular side (EC) of the membrane. Reprotonation of the retinal molecule by Asp96 restores its original isomerized form. This results in a second proton being released to the EC side. Asp85 releases its proton into the \"holding site,\" where a new cycle may begin. The bacteriorhodopsin molecule is purple and is most efficient at absorbing green light (wavelength 500-650 nm, with the absorption maximum at 568 nm). Bacteriorhodopsin has a broad excitation spectrum. For a detection wavelength between 700 and 800 nm, it has an appreciable detected emission for excitation wavelengths between 470 nm and 650 nm (with a peak at 570 nm). When pumped at 633 nm, the emission spectrum has appreciable intensity between 650 nm and 850 nm. Bacteriorhodopsin belongs to the microbial rhodopsins. They have similarities to vertebrate rhodopsins, the pigments that sense light in the retina. Rhodopsins also contain retinal; however, the functions of rhodopsin and bacteriorhodopsin are different, and there is limited similarity in their amino acid sequences. Both rhodopsin and bacteriorhodopsin belong to the 7TM receptor family of proteins, but rhodopsin is a G protein-coupled receptor and bacteriorhodopsin is not. In the first use of electron crystallography to obtain an atomic-level protein structure, the structure of bacteriorhodopsin was resolved in 1990. It was then used as a template to build models of G protein-coupled receptors before crystallographic structures were also available for these proteins. It has been excessively studied on both mica and glass substrates using Atomic force microscopy and Femtosecond crystallography. Many proteins have homology to bacteriorhodopsin, including the light-driven chloride pump halorhodopsin (for which the crystal structure is also known), and some directly light-activated channels like channelrhodopsin. All other phototrophic systems in bacteria, algae, and plants use chlorophylls or bacteriochlorophylls rather than bacteriorhodopsin. These also produce a proton gradient, but in a quite different and more indirect way involving an electron transfer chain consisting of several other proteins. Furthermore, chlorophylls are aided in capturing light energy by other pigments known as \"antennas\"; these are not present in bacteriorhodopsin-based systems.

It was the first ever car built with front-engine, four-wheel-drive layout, and its engine with six cylinders was also a world's first.

In 1907, an 18 hp model competed in the 15,000 km Peking to Paris monster race, finishing second in the most gruelling race of its time.

Thus, there is not only an individual memory, but also a group memory that exists outside of and lives beyond the individual. Consequently, an individual's understanding of the past is strongly linked to this group consciousness. This idea of memory Halbwachs pursued to prove through peoples expression of commemoration in our culture. Commemoration offers collective memory tie to society and its conceptions where physical monuments and rituals fix and affirm collectivity. Halbwachs Collective Memory includes two laws governing how this form of memory will evolve. The two laws are called a Law of Fragmentation, and a Law of Concentration. Halbwachs also wrote an important book on suicide, \"Les Causes du suicide\", 1930 (\"The Causes of Suicide\"). In this book he followed the footsteps of his mentor Émile Durkheim, expanding and elaborating upon the former's theories on suicide. Specifically, he focused on ideas such as, the ways in which rural and urban styles of life explain variations in suicide rates. Halbwachs also continued to further Durkheim's conceptualization of how specific family styles and religious backgrounds alter rates of suicide.

Wilhelmine spent her earliest childhood in Mitau. In 1795 the Duke was forced to cede his Duchy to the Russian Empire, and the family moved to the Duchy of Sagan (Żagań) in Silesia, which had been acquired in 1786. Among other properties bought by her father during the 1780s was County Náchod in Bohemia, which included Ratibořice Castle. Wilhelmine, who inherited both Sagan and Náchod, selected this castle as her summer residence. The young duchess was very beautiful, intelligent, eloquent and educated in philosophy and history.

She also undertook journeys to Italy, England and France. Her second marriage with prince Vasily Troubetzkoy (1776–1841), which lasted from 1805 to 1806, also ended in divorce.

The negotiations in 1813 that resulted in an anti-Napoleonic coalition between Prussia, Austria and Russia were held in one of Wilhelmine's homes, Ratibořice Castle. During the Congress of Vienna (1814–15), the relationship ended, as Wilhelmine didn't like playing the role of an unacknowledged mistress, a role forced onto her as Metternich was married, and also because Alfred Windischgraetz (alternative spelling) appeared in Vienna, and she could not resist resuming her affair with him, writing \"with friends one counts the days, with you I count the nights, and I would not wish to miss a single one of them\".

Blackboard chalk manufacturers now may use mineral chalk, other mineral sources of calcium carbonate, or the mineral gypsum (calcium sulfate). While gypsum-based blackboard chalk is the lowest cost to produce, and thus widely used in the developing world, calcium-based chalk can be made where the crumbling particles are larger and thus produce less dust, and is marketed as \"dustless chalk\". Colored chalks, pastel chalks, and sidewalk chalk (shaped into larger sticks and often colored), used to draw on sidewalks, streets, and driveways, are primarily made of gypsum. Chalk is a source of quicklime by thermal decomposition, or slaked lime following quenching of quicklime with water. In southeast England, deneholes are a notable example of ancient chalk pits. Such bell pits may also mark the sites of ancient flint mines, where the prime object was to remove flint nodules for stone tool manufacture. The surface remains at Cissbury are one such example, but perhaps the most famous is the extensive complex at Grimes Graves in Norfolk. Woodworking joints may be fitted by chalking one of the mating surfaces. A trial fit will leave a chalk mark on the high spots of the corresponding surface. Chalk transferring to cover the complete surface indicates a good fit. Builder's putty also mainly contains chalk as a filler in linseed oil. Chalk may be used for its properties as a base. In agriculture, chalk is used for raising pH in soils with high acidity. The most common forms are CaCO (calcium carbonate) and CaO (calcium oxide). Small doses of chalk can also be used as an antacid. Additionally, the small particles of chalk make it a substance ideal for cleaning and polishing.

In the Danish Land Book, Järve and Kukruse villages were first mentioned in 1241 by the names \"Jeruius\" and \"Kukarus\" respectively, and Sompa village in 1420 by the name \"Soenpe\". Local residents were aware of oil shale's flammable capability in ancient times, but its industrial extraction in Estonia began only in the 20th century. In 1916, researches showed that oil shale could be used both as fuel and as a raw material for chemical industry, and mining started near Järve village. In 1919 the State Oil Shale Industrial Corporation was formed and extraction by shaft and open-pit mining was extended. Settlements for workers began to appear adjacent to the mines. In 1924 the oil shale processing factory was built near Kohtla railway station, and the nearby settlement, named Kohtla-Järve, started to grow. During World War II the value of the Estonian oil shale deposit grew. The Germans, who occupied Estonia, considered it as an important source of fuel. However, they failed to begin full-scale extraction. After the war, the next occupier of Estonia, the Soviet Union, required constantly increasing quantities of oil shale for its industries and extraction greatly expanded. Kohtla-Järve, as the main settlement in the mining area, received city status on 15 June 1946. Since that time, during the next twenty years, there was a process of administrative amalgamation of neighboring settlements within the limits of Kohtla-Järve. Kohtla and Kukruse were added to the city in 1949; Jõhvi, Ahtme and Sompa in 1960. The town of Kiviõli and the boroughs of Oru, Püssi and Viivikonna were subordinated to the city in 1964. Thus, Kohtla-Järve greatly expanded, becoming a city with a unique layout, as its parts remained scattered among woods, agricultural areas and oil shale mines. Total population of the city increased mainly by workers sent from different parts of Soviet Union, reaching (with subordinated settlements) 90,000 in 1980. After Soviet Union collapsed and Estonia regained independence in 1991 the number of city districts decreased, as Jõhvi, Kiviõli and Püssi became separate towns.

Seamen rescued from the ships sunk by \"Admiral Graf Spee\" were transferred to \"Altmark\". After \"Admiral Graf Spee\" was heavily damaged by British cruisers in Battle of the River Plate and subsequently scuttled by her crew, in the Río de la Plata in December 1939, \"Altmark\" attempted to return to Germany, steaming around the north of Great Britain and then within the Norwegian littoral. On 14 February 1940 \"Altmark\", proceeding south within Norwegian territorial waters, was discovered by three British Lockheed Hudson Mk.II aircraft from RAF Thornaby and pursued by several British destroyers led by. Late on 16 February 1940 in Jøssingfjord she was fired upon while the Norwegian Navy stood by and took no action save for raising a protest flag. The German tanker then received a boarding party from HMS \"Cossack\". During an attempted escape across the ice, seven of the \"Altmark\" crew were shot down. During the skirmish \"Altmark\" was run onto the rocks. It had been the British intention to tow the ship back to a Scottish port, but the damage to the tanker's stern frustrated this idea. An attack by one belligerent upon its enemy in neutral waters is a breach of neutrality, in this case a breach of Norwegian neutrality by Britain. Because Hitler feared Norway would be insufficiently resolute to protect the German iron-ore traffic that passed legitimately along the Norwegian littoral, at Admiral Erich Raeder's urging he decided on the invasion of Norway and Denmark in March 1940. The British justification for the attack on the \"Altmark\" was set out in a Note to the Norwegian Government from Foreign Secretary Lord Halifax dated 10 March 1940. The problem the British Government faced was the wording of The Hague Convention XIII of 1907 to which it was a signatory. Article 10 provides that: \"The neutrality of a Power is not affected by the mere passage through its territorial waters of warships or prizes belonging to belligerents.\" This meant that the \"Altmark\" was within its rights to sail through Norwegian waters with prisoners aboard providing that it did not come to a protracted stop longer than 24 hours. In the diplomatic letter, the British government confirmed that it was not contrary to the law of neutrality to sail a prison ship through neutral waters, and Britain often did this herself. In fact the British complaint had nothing to do with the prisoners. \"Altmark\" was a fleet tanker assimilated to a warship and was proceeding to Germany from the Atlantic by the north-about route. Instead of sailing down the North Sea as he would do in peacetime, the master of the \"Altmark\" had elected to sail the entire leg of the voyage southwards within Norwegian territorial waters in order to attract immunity from attack there under international law. There was no other reason for him to want to voyage through waters so dangerous to navigation. With no valid breach of international law, the British excused their violation of international law by contriving that the \"Altmark's\" course abused international law even without a violation, and since the Norwegians had declined to stop a voyage that was not in violation of international convention the British Admiralty decided it was justified in taking action contrary to law, essentially announcing that it had the right to determine what course an enemy ship must travel to be entitled to the protections of international law.

The cause of the explosion was thought to be a spark from tools used by a repair gang working near the cargo tanks. The \"Uckermark\" had delivered 5000ts of gasoline to Yokohama. It seems to be logical that the residual fumes and gasoline did explode. Diesel fuel does not explode the way the ship went up. 53 crewmen from \"Uckermark\" died in the explosion.

Two other firsthand reports of the plague's ravages were by the Syriac church historian John of Ephesus and Evagrius Scholasticus, who was a child in Antioch at the time and later became a church historian. Evagrius was afflicted with the buboes associated with the disease but survived. During the disease's four returns in his lifetime, he lost his wife, a daughter and her child, other children, most of his servants and people from his country estate. According to contemporary sources, the outbreak in Constantinople was thought to have been carried to the city by infected rats on grain ships arriving from Egypt. To feed its citizens, the city and outlying communities imported large amounts of grain, mostly from Egypt. The rat (and flea) population in Egypt thrived on feeding from the large granaries maintained by the government. Procopius, in a passage closely modelled on Thucydides, recorded that at its peak the plague was killing 10,000 people in Constantinople daily, but the accuracy of the figure is in question, and the true number will probably never be known. He noted that because there was no room to bury the dead, bodies were left stacked in the open. Funeral rites were often left unattended to, and the entire city smelled like the dead. In his \"Secret History,\" he records the devastation in the countryside and reports the ruthless response by the hard-pressed Justinian: When pestilence swept through the whole known world and notably the Roman Empire, wiping out most of the farming community and of necessity leaving a trail of desolation in its wake, Justinian showed no mercy towards the ruined freeholders. Even then, he did not refrain from demanding the annual tax, not only the amount at which he assessed each individual, but also the amount for which his deceased neighbors were liable. As a result of the plague in the countryside, farmers could not take care of crops and the price of grain rose in Constantinople. Justinian had expended huge amounts of money for wars against the Vandals in the region of Carthage and the Ostrogoths' kingdom in Italy. He had invested heavily in the construction of great churches, such as Hagia Sophia. As the empire tried to fund the projects, the plague caused tax revenues to decline through the massive number of deaths and the disruption of agriculture and trade. Justinian swiftly enacted new legislation to deal more efficiently with the glut of inheritance suits being brought as a result of victims dying intestate. The plague's long-term effects on European and Christian history were enormous. As the disease spread to port cities around the Mediterranean, the struggling Goths were reinvigorated and their conflict with Constantinople entered a new phase. The plague weakened the Byzantine Empire at a critical point, when Justinian's armies had nearly retaken all of Italy and the western Mediterranean coast; the evolving conquest would have reunited the core of the Western Roman Empire with the Eastern Roman Empire. Although the conquest occurred in 554, the reunification did not last long. In 568, the Lombards invaded Northern Italy, defeated the small Byzantine army that had been left behind and established the Kingdom of the Lombards.

Genetic studies of modern and ancient \"Yersinia pestis\" DNA suggest that the origin of the Justinian plague was in Central Asia. The most basal or root level existing strains of the \"Yersinia pestis\" as a whole species are found in Qinghai, China. After samples of DNA from \"Yersinia pestis\" were isolated from skeletons of Justinian plague victims in Germany, it was found that modern strains currently found in the Tian Shan mountain range system are most basal known in comparison with the Justinian plague strain. Additionally, a skeleton found in Tian Shan dating to around 180 AD and identified as an \"early Hun\" was found to contain DNA from \"Yersinia pestis\" closely related to the Tian Shan strain basal ancestor of the Justinian plague strain German samples. This finding suggests that the expansion of nomadic peoples who moved across the Eurasian steppe, such as the Xiongnu and the later Huns, had a role in spreading plague to West Eurasia from an origin in Central Asia. Earlier samples of \"Yersinia pestis\" DNA have been found in skeletons dating from 3000–800 BC, across West and East Eurasia.

His early works use his own compositions, combining elements from Francia and other North Italian artists, and like all Italian printmakers in these years he was strongly affected by the enormously accomplished prints of Dürer, which were widely distributed in Italy.

The factor behind Artabanus' rise to kingship of Media Atropatene is unclear. The kingdom served as Artabanus' headquarters of his attacks against the Parthian king Vonones I (), with whom he fought against over the crown. Vonones I, who had originally resided in Rome, had been placed on the Parthian throne by a faction led by the Karin and Suren clans. His rule was supported by the Romans.

This was attempt instantly opposed by the Romans, who regarded this as posing a danger to their interests. As a result, the Roman emperor Tiberius () sent his stepson Germanicus to prevent this from happening. However, the Roman general was met with no resistance by the Parthians, and reached an agreement with Artabanus to appoint Artaxias III the new king of Armenia and renounce their support of Vonones I. The Romans thus acknowledged Artabanus as the legitimate Parthian ruler. In order to ratify the friendly relationship between the two empires, Artabanus and Germanicus met on an island in the Euphrates in 18. The Romans moved Vonones I to Cilicia, where he was killed the following year after attempting to flee. His death and the now unchallenged dominance of Artabanus split the Parthian nobility, since not all of them supported a new branch of the Arsacid family taking over the empire. In 19/20, the Parthian satrap of Sakastan, Drangiana and Arachosia, named Gondophares, declared independence from Artabanus and founded the Indo-Parthian Kingdom. He assumed the titles of \"Great King of Kings\" and \"\"Autokrator\"\", demonstrating his new-found independence. Nevertheless, Artabanus and Gondophares most likely reached an agreement that the Indo-Parthians would not intervene in the affairs of the Arsacids. Artabanus spent the following years increasing his authority. To the northeast, he was victorious in his efforts to have a new dynasty established in Khwarazm, thus starting a new era in the history of the country. Artabanus most likely operated in western Bactria as well, which had been part of the Parthian domains for centuries. In AD 35, he tried a new way to conquer Armenia and to establish his son Arsaces I as King there. A war with Rome seemed inevitable. The faction among the Parthian magnates which was hostile to Artabanus II applied to Tiberius for a king of the race of Phraates IV. Tiberius sent Phraates IV's grandson, Tiridates III, and ordered Lucius Vitellius the Elder (the father of the Roman emperor Vitellius) to restore Roman authority in the East. By very dexterous military and diplomatic operations Vitellius succeeded completely. Artabanus II was deserted by his followers and fled to the East. Tiridates III, who was proclaimed King, could no longer maintain himself, because he appeared to be a vassal of the Romans. Artabanus II returned from Hyrcania with a strong army of Scythian (Dahae) auxiliaries and was again acknowledged by the Parthians. Tiridates III left Seleucia and fled to Syria. Artabanus II wasn’t strong enough for a war with Rome; he therefore concluded a treaty with Vitellius in 37, in which he gave up all further pretensions. A short time afterwards Artabanus II was deposed again, and a certain Cinnamus was proclaimed king. Artabanus II took refuge with his vassal, the King Izates bar Monobaz. Izates, by negotiations and the promise of a complete pardon, induced the Parthians to restore Artabanus II once more to the throne.

Hermann's mother was a member of the House of Kotromanić, daughter of Ban Stephen II of Bosnia and thus cousin of the first King of Bosnia, Tvrtko I.

The Christian coalition was soundly defeated. Hermann saved Sigismund's life. The two escaped the battlefield on the same fishing boat and underwent a long journey back to Hungary together. Sigismund rewarded Hermann by assigning to him the district of Varaždin in 1397, followed in 1399 by various other districts in Zagorje along the border of the Kingdom of Croatia and the Holy Roman Empire. These grants were hereditary and made the Celje counts the greatest landowners in Slavonia; from then on, they styled themselves \"counts of Celje and Zagorje\". Hermann's loyalty persisted during the Hungarian civil war, when Sigismund's kingdoms of Croatia and Hungary were being claimed by King Ladislaus of Naples with the support of Sigismund's rebellious vassals. The rebels succeeded in capturing and imprisoning Sigismund in 1401. Hermann and the Palatine of Hungary Nicholas II Garay procured his release later that year, after Hermann threatened to invade Hungary. The relations between the two men then became even closer. Sigismund had promised to remove foreigners such as Hermann from state offices upon being liberated, but never carried out the promise. In 1405, Sigismund married Hermann's youngest daughter Barbara and granted extensive lands in Slavonia to his father-in-law. Anne, another daughter of Hermann, was married to the Palatine, linking the three families through affinity. In 1406, Sigismund named Hermann Ban of Dalmatia and Croatia and Ban of Slavonia. He held these offices until 1408 and again from 1423 until 1435, benefiting from the dedicated support of Eberhard, the German-born Bishop of Zagreb. All of this made the House of Celje the most powerful family in the Kingdom of Croatia. Hermann was one of the founding members of Sigismund's elite Order of the Dragon, established in 1408. For reasons of economy rather than religious fanaticism, Hermann expelled all Jews from his domain. When Count Frederick III of Ortenburg, the last of his line, died in 1418, his domain was inherited by Hermann. From then on, he controlled three quarters of Carinthia. This made it easier for him to attain imperial immediacy, his family's long-set goal. The marriage of his son Louis and Duke Ernest of Bavaria's daughter Beatrix provided Hermann with a powerful ally against his Habsburg overlords. His goal was finally achieved in 1423 when Duke Ernest of Styria and Carinthia renounced his feudal supremacy over the counts of Celje. This was a reward by Sigismund, also King of Germany since 1411, for Hermann's successful negotiation with the dissatisfied Croatian nobles. It came with the right of coinage as well as the right to collect tolls and revenues from various mines. Now enjoying a direct legal relationship with the Crown, Hermann was free to concentrate on a new goal: becoming Prince of the Holy Roman Empire.

The Bosnian nobility was outraged by the demand. Hermann's accession would have meant an increased influence of Hungary over Bosnia, something they were determined to prevent. Besides, they were used to controlling the royal succession and considered it their right to elect kings. They also feared that Hermann, whose domain enveloped Bosnia, would assist Tvrtko in curbing their power and privileges.

He became a Russophile and a Pan-Slav, but after recognizing the true reality of the Russian society he took the pessimistic view that \"Pan-Slavism is a great, attractive but feckless idea\". His memories of the Russian stay were published first in magazines and then as a book \"Obrazy z Rus\" (\"Pictures from Russia\"). He returned to Bohemia in 1844, aged 24 and used his writing skills to criticize the fashion of embracing anything written in the recently reborn Czech language. He specifically aimed at a novel by Josef Kajetán Tyl. In 1846 Havlíček attained a position as editor of the \"Pražské noviny\" newspaper with the help of František Palacký. In April 1848 he changed the name of the newspaper to \"Národní noviny\" (\"National News\") and it became one of the first newspapers of the Revolutionary-era Czech liberals, and one of the most influential publications of 1848-1849. \"Národní noviny\" became popular especially for his sharp-tongued epigrams and its wit. Havlíček was concerned with the preparations of the Congress of the Slavs in Prague. In July 1848 he was elected as a member of the Austrian Empire Constituent Assembly in Vienna and later in Kroměříž. He eventually relinquished his seat to focus on journalism. Havlíček was a \"liberal nationalist\" politically, but refused to allow a \"party line\" to inform his opinions. Often, he would criticize those that agreed with him as much as those that disagreed. He excoriated revolutionaries for their radicalism, but also advocated ideas like universal suffrage-a concept altogether too radical for most of his fellow liberals. He was a pragmatist, and had little patience for those that spent their time romanticizing the Czech nationality without helping it achieve political or cultural independence. He used much of the space in his newspapers to educate the people on important issues-stressing areas like economics, which were sorely neglected by other nationalist writers. The Bohemian revolution was defeated in March 1849 with the dissolution of the Kroměříž assembly, but Havlíček continued to criticize the new regime. He was brought to court for his criticism (there was no freedom of the press in the Habsburg's territory) but was found not guilty by a sympathetic jury. \"Národní noviny\" had to cease publication in January 1850, but Havlíček did not end his activities. In May 1850 he began publishing the magazine \"Slovan\" in Kutná Hora. The magazine was a target of censorship from the start. It had to stop publication in August 1851, and Havlíček stood again at the court to answer on charges of dissent. Again, he was found not guilty by a sympathetic jury of Czech commoners. Havlíček translated and introduced some satirical and critical authors into the Czech language culture including Nikolai Gogol (1842) and Voltaire (1851). In the night of December 16, 1851, he was arrested by the police and forced into exile in Brixen, Austria (present-day Italy).

A rule in a chain can cause a goto or jump to another chain, and this can be repeated to whatever level of nesting is desired. (A jump is like a “call”, i.e. the point that was jumped from is remembered.) Every network packet arriving at or leaving from the computer traverses at least one chain. The origin of the packet determines which chain it traverses initially. There are five \"predefined chains\" (mapping to the five available Netfilter hooks), though a table may not have all chains. Predefined chains have a \"policy\", for example DROP, which is applied to the packet if it reaches the end of the chain. The system administrator can create as many other chains as desired. These chains have no policy; if a packet reaches the end of the chain it is returned to the chain which called it. A chain may be empty. A chain does not exist by itself; it belongs to a \"table\". There are three tables: \"nat\", \"filter\", and \"mangle\". Unless preceded by the option \"-t\", an iptables command concerns the \"filter\" table by default. For example, the command \"iptables -L -v -n\", which shows some chains and their rules, is equivalent to \"iptables -t filter -L -v -n\". To show chains of table \"nat\", use the command \"iptables -t nat -L -v -n\" Each rule in a chain contains the specification of which packets it matches. It may also contain a \"target\" (used for extensions) or \"verdict\" (one of the built-in decisions). As a packet traverses a chain, each rule in turn is examined. If a rule does not match the packet, the packet is passed to the next rule. If a rule does match the packet, the rule takes the action indicated by the target/verdict, which may result in the packet being allowed to continue along the chain or may not. Matches make up the large part of rulesets, as they contain the conditions packets are tested for. These can happen for about any layer in the OSI model, as with e.g. the codice_8 and codice_9 parameters, and there are also protocol-independent matches, such as codice_10.

Aristotle regarded quantity as a fundamental ontological and scientific category. In Aristotle's ontology, quantity or quantum was classified into two different types, which he characterized as follows: In his \"Elements\", Euclid developed the theory of ratios of magnitudes without studying the nature of magnitudes, as Archimedes, but giving the following significant definitions: For Aristotle and Euclid, relations were conceived as whole numbers (Michell, 1993). John Wallis later conceived of ratios of magnitudes as real numbers as reflected in the following: That is, the ratio of magnitudes of any quantity, whether volume, mass, heat and so on, is a number. Following this, Newton then defined number, and the relationship between quantity and number, in the following terms: \"By \"number\" we understand not so much a multitude of unities, as the abstracted ratio of any quantity to another quantity of the same kind, which we take for unity\" (Newton, 1728).", "section_level": 1}, {"title": "Quantitative structure.", "content": "Continuous quantities possess a particular structure that was first explicitly characterized by Hölder (1901) as a set of axioms that define such features as \"identities\" and \"relations\" between magnitudes. In science, quantitative structure is the subject of empirical investigation and cannot be assumed to exist \"a priori\" for any given property. The linear continuum represents the prototype of continuous quantitative structure as characterized by Hölder (1901) (translated in Michell & Ernst, 1996). A fundamental feature of any type of quantity is that the relationships of equality or inequality can in principle be stated in comparisons between particular magnitudes, unlike quality, which is marked by likeness, similarity and difference, diversity. Another fundamental feature is additivity. Additivity may involve concatenation, such as adding two lengths A and B to obtain a third A + B. Additivity is not, however, restricted to extensive quantities but may also entail relations between magnitudes that can be established through experiments that permit tests of hypothesized observable manifestations of the additive relations of magnitudes. Another feature is continuity, on which Michell (1999, p. 51) says of length, as a type of quantitative attribute, \"what continuity means is that if any arbitrary length, a, is selected as a unit, then for every positive real number, \"r\", there is a length b such that b = \"r\"a\".

In formal terms, quantities—their ratios, proportions, order and formal relationships of equality and inequality—are studied by mathematics. The essential part of mathematical quantities consists of having a collection of variables, each assuming a set of values. These can be a set of a single quantity, referred to as a scalar when represented by real numbers, or have multiple quantities as do vectors and tensors, two kinds of geometric objects. The mathematical usage of a quantity can then be varied and so is situationally dependent. Quantities can be used as being infinitesimal, arguments of a function, variables in an expression (independent or dependent), or probabilistic as in random and stochastic quantities. In mathematics, magnitudes and multitudes are also not only two distinct kinds of quantity but furthermore relatable to each other. Number theory covers the topics of the discrete quantities as numbers: number systems with their kinds and relations. Geometry studies the issues of spatial magnitudes: straight lines, curved lines, surfaces and solids, all with their respective measurements and relationships. A traditional philosophy of mathematics, stemming from Aristotle and remaining popular until the eighteenth century, held that mathematics is the \"science of quantity\". Quantity was considered to be divided into the discrete (studied by arithmetic) and the continuous (studied by geometry and later calculus).

Physics is fundamentally a quantitative science. Its progress is chiefly achieved due to rendering the abstract qualities of material entities into physical quantities, by postulating that all material bodies marked by quantitative properties or physical dimensions are subject to some measurements and observations. Setting the units of measurement, physics covers such fundamental quantities as space (length, breadth, and depth) and time, mass and force, temperature, energy, and quanta. A distinction has also been made between intensive quantity and extensive quantity as two types of quantitative property, state or relation. The magnitude of an \"intensive quantity\" does not depend on the size, or extent, of the object or system of which the quantity is a property, whereas magnitudes of an \"extensive quantity\" are additive for parts of an entity or subsystems.

The growth in the design was in part to answer a question that always dogged U.S. Navy designs, that being the long range required by operations in the Pacific Ocean. They were also to carry no less than five guns and ten deck-mounted torpedo tubes on the centerline, allowing them to meet any foreign design on equal terms. Compared to earlier designs, the \"Fletcher\"s were large, allowing them to eventually absorb the addition of two 40 mm Bofors quadruple mount AA guns as well as six 20 mm Oerlikon dual AA gun positions. This addition to the AA suite required the deletion of the forward quintuple torpedo mount, a change done under the 4 April 1945 anti-\"kamikaze\" program. \"Fletcher\"s were also much less top-heavy than previous classes, allowing them to take on additional equipment and weapons without major redesign. They were fortunate in catching American production at the right moment, becoming \"the\" destroyer design, and only \"Fletcher\"-class derivatives, the \"Sumner\" and \"Gearing\" classes, would follow it. The first design inputs were in the fall of 1939 from questionnaires distributed around design bureaus and the Office of the Chief of Naval Operations. The design parameters were the armaments desired of the next destroyer. As such, the questions were of how many guns, torpedoes, and depth charges were seen as desirable. Also asked was at what point would the design grow large enough to become a torpedo target instead of a torpedo delivery system. The answer that came back was that five dual purpose guns, twelve torpedoes, and twenty-eight depth charges would be ideal, while a return to the 1500-ton designs of the past was seen as undesirable. Speed requirements varied from, and shortcomings in the earlier \"Sims\" class, which were top heavy and needed lead ballast to correct this fault, caused the \"Fletcher\" design to be widened by of beam. As with other previous U.S. flush deck destroyer designs, seagoing performance suffered. This was mitigated by deployment to the Pacific Ocean, which is relatively calm. To achieve with a 500-ton increase in displacement, shaft horsepower was increased from 50,000 to 60,000 compared to the previous \"Benson\" and \"Gleaves\" classes.

Ten torpedo tubes were fitted in two quintuple mounts on the centerline amidships, firing the 21-inch Mark 15 torpedo. Anti-submarine armament was two depth charge racks for 600-pound charges at the stern, augmented by six K-gun depth charge throwers for 300-pound charges amidships. Besides the main dual-purpose guns, initial (April-May 1942) anti-aircraft armament was light; a quadruple 1.1\"/75 caliber gun (located in an elevated tub between the number three and four 5\"/38 caliber gun mounts), and six Oerlikon 20 mm cannons (two in front of and below the bridge, and four amidships). Beginning in June 1942, the 1.1\" gun was replaced by a twin Bofors 40 mm gun mount, plus another twin mount on the fantail between the depth charge racks. In February 1943, the fantail-mounted Bofors was removed, and instead, one twin mount was placed on each side of the aft funnel, bringing the total number of 40 mm barrels to six. In 1942 and 1943, the number of Oerlikon cannons was steadily increased. Ships were often modified before leaving the shipyard with a seventh 20 mm mount in front of the bridge behind the number two 5\"/38 caliber gun mount, and anywhere from one to three mounts on the flying bridge depending upon the bridge configuration of the ship. In combat, commanders often requisitioned additional guns, and some Fletchers mounted up to thirteen 20 mm cannons. In June and July 1943, two more twin Bofors mounts were added in place of the 20 mm cannons in front of and below the bridge, giving a total of ten barrels. With this modification, the Oerlikon cannons were rearranged and their number was standardized at seven; four amidships and three in a heart-shaped mount on the fantail. Due to the increasing threat from \"kamikaze\" attacks, beginning in July 1945 some ships returning to the United States for refit received further antiaircraft modifications, replacing the forward set of quintuple torpedo tubes with a large gun platform housing two quadruple 40 mm guns (for a total of fourteen barrels). The seven single 20 mm guns were replaced with six twin mounts (four amidships and two on the fantail, rather than three as before).

Another important aspect of the neo-Kantian movement was its attempt to promote a revised notion of Judaism, particularly in Cohen's seminal work, one of the few works of the movement available in English translation. The neo-Kantian school was of importance in devising a division of philosophy that has had durable influence well beyond Germany. It made early use of terms such as epistemology and upheld its prominence over ontology. Natorp had a decisive influence on the history of phenomenology and is often credited with leading Edmund Husserl to adopt the vocabulary of transcendental idealism. Emil Lask was influenced by Edmund Husserl's work, and himself exerted a remarkable influence on the young Martin Heidegger. The debate between Cassirer and Heidegger over the interpretation of Kant led the latter to formulate reasons for viewing Kant as a forerunner of phenomenology; this view was disputed in important respects by Eugen Fink. An abiding achievement of the neo-Kantians was the founding of the journal \"Kant-Studien\", which still survives today.

Around the same time as Strawson, Wilfrid Sellars also renewed interest in Kant's philosophy. His project of introducing a Kantian turn in contemporary analytic philosophy has been taken up by his student Robert Brandom. Brandom's work has transformed Sellars' project to introducing a Hegelian phase in analytic philosophy. In the 1980s, interest in neo-Kantianism has revived in the wake of the work of Gillian Rose, who is a critic of this movement's influence on modern philosophy, and because of its influence on the work of Max Weber. The Kantian concern for the limits of perception strongly influenced the antipositivist sociological movement in late 19th-century Germany, particularly in the work of Georg Simmel (Simmel's question 'What is society?' is a direct allusion to Kant's own: 'What is nature'?).

He also spent two years in the United States Air Force. Westlake moved to New York City in 1959, initially to work for a literary agency while writing on the side. By 1960, he was writing full-time. His first novel under his own name, \"The Mercenaries\", was published in 1960; over the next 48 years, Westlake published a variety of novels and short stories under his own name and a number of pseudonyms. He was married three times, the final time to Abigail Westlake (also known as Abby Adams Westlake and Abby Adams), a writer of nonfiction (her two published books are \"An Uncommon Scold\" and \"The Gardener's Gripe Book\").

Neither the film's producer nor Godard purchased the rights to the novel, so Westlake successfully sued to prevent the film's commercial distribution in the United States. Westlake was himself a screenwriter. His script for the 1990 film \"The Grifters,\" adapted from the novel by Jim Thompson, was nominated for an Academy Award. (Westlake the screenwriter adapted Jim Thompson's work in a straightforward manner, but Westlake the humourist played on Thompson's name later that year in the Dortmunder novel \"Drowned Hopes\" by featuring a character named \"Tom Jimson\" who is a criminal psychopath.) Westlake also wrote the screenplay \"The Stepfather\" (from a story by Westlake, Brian Garfield and Carolyn Lefcourt), the film of which was popular enough to inspire two sequels and a remake, projects in which Westlake was not involved. In 1987 Westlake wrote the teleplay \"Fatal Confession\", a pilot for the TV series \"Father Dowling Mysteries\" based on the novels by Ralph McInerny. He also appeared in a small role (as the mystery writer Rich Vincent) in the third-season episode, \"The Hardboiled Mystery.\" While the seventeenth James Bond film \"GoldenEye\" was in post-production, Westlake wrote story treatments for the eighteenth James Bond film (eventually titled \"Tomorrow Never Dies\") in collaboration with Bond series writer-producer Michael G.

The ninth century theologian Abu al-Hasan al-Ash'ari argued that there is no Secondary Causation in the created order. The world is sustained and governed through direct intervention of a divine primary causation. As such the world is in a constant state of recreation by God. The most famous proponent of the Asharite occasionalist doctrine was Abu Hamid Muhammad ibn Muhammad al-Ghazali, an 11th-century theologian based in Baghdad. In \"The Incoherence of the Philosophers\", Al-Ghazali launched a philosophical critique against Neoplatonic-influenced early Islamic philosophers such as Al-Farabi and Ibn Sina. In response to the philosophers' claim that the created order is governed by secondary efficient causes (God being, as it were, the Primary and Final Cause in an ontological and logical sense), Ghazali argues that what we observe as regularity in nature based presumably upon some natural law is actually a kind of constant and continual regularity. There is no independent necessitation of change and becoming, other than what God has ordained. To posit an independent causality outside of God's knowledge and action is to deprive Him of true agency, and diminish his attribute of power. In his famous example, when fire and cotton are placed in contact, the cotton is burned not because of the heat of the fire, but through God's direct intervention, a claim which he defended using logic. In the 12th century, this theory was defended and further strengthened by the Islamic theologian Fakhr al-Din al-Razi, using his expertise in the natural sciences of astronomy, cosmology and physics. Because God is usually seen as rational, rather than arbitrary, his behaviour in normally causing events in the same sequence (i.e., what appears to us to be efficient causation) can be understood as a natural outworking of that principle of reason, which we then describe as the laws of nature. Properly speaking, however, these are not laws of nature but laws by which God chooses to govern his own behaviour (his autonomy, in the strict sense) — in other words, his rational will. This is not, however, an essential element of an occasionalist account, and occasionalism can include positions where God's behaviour (and thus that of the world) is viewed as ultimately inscrutable, thus maintaining God's essential transcendence. On this understanding, apparent anomalies such as miracles are not really such: they are simply God behaving in a way that \"appears\" unusual \"to us\". Given his transcendent freedom, he is not bound even by his own nature. Miracles, as breaks in the rational structure of the universe, can occur, since God's relationship with the world is not mediated by rational principles. In a 1978 article in \"Studia Islamica\", Lenn Goodman asks the question, \"Did Al-Ghazâlî Deny Causality?\" and demonstrates that Ghazali did not deny the existence of observed, \"worldly\" causation. According to Goodman's analysis, Ghazali does not claim that there is never any link between observed cause and observed effect: rather, Ghazali argues that there is no \"necessary\" link between observed cause and effect.", "section_level": 1}, {"title": "Dualism.", "content": "One of the motivations for the theory is the dualist belief that mind and matter are so utterly different in their essences that one cannot affect the other. Thus, a person's mind cannot be the true cause of his hand's moving, nor can a physical wound be the true cause of mental anguish. In other words, the mental cannot cause the physical and vice versa. Also, occasionalists generally hold that the physical cannot cause the physical either, for no necessary connection can be perceived between physical causes and effects. The will of God is taken to be necessary. The doctrine is, however, more usually associated with certain seventeenth century philosophers of the Cartesian school. There are hints of an occasionalist viewpoint here and there in Descartes's own writings, but these can mostly be explained away under alternative interpretations. However, many of his later followers quite explicitly committed themselves to an occasionalist position.

George Berkeley was also inspired by the occasionalists, and he agreed with them that no efficient power could be attributed to bodies. For Berkeley, bodies merely existed as ideas in percipient minds, and all such ideas were, as he put it, \"visibly inactive\". However, Berkeley disagreed with the occasionalists by continuing to endow the created minds themselves with efficient power. Gottfried Wilhelm Leibniz agreed with the occasionalists that there could be no efficient causation between distinct created substances, but he did not think it followed that there was no efficient power in the created world at all. On the contrary, every simple substance had the power to produce changes in \"itself\". The illusion of transeunt efficient causation, for Leibniz, arose out of the pre-established harmony between the alterations produced immanently within different substances.

Another intermediary was Jozef Retinger, a London-based Polish literary scholar and budding politician who was a friend of Sixtus, Xavier and Zita de Bourbon-Parma and who had received backing from the British to support the initiative. Sixtus arrived with French-agreed conditions for talks: the restoration to France of Alsace-Lorraine (annexed by Germany after the Franco-Prussian War in 1870); restoration of the independence of Belgium; independence for the kingdom of Serbia; and the handover of Constantinople to Russia. Charles agreed, in principle, to the first three points and wrote a letter dated 25 March 1917, to Sixtus giving \"the secret and unofficial message that I will use all means and all my personal influence\" to the President of France.

In the 9th century the island's population began to grow, and in the following centuries its importance grew steadily, until it was governed by a dedicated Podestà. In 1379 Venice came under attack from the Genoan fleet; the people of Poveglia were moved to the Giudecca. The island remained uninhabited in the subsequent centuries; in 1527 the doge offered the island to the Camaldolese monks, who refused the offer. From 1645 on, the Venetian government built five octagonal forts to protect and control the entrances to the lagoon. The Poveglia octagon is one of four that still survive. In 1776 the island came under the jurisdiction of the \"Magistrato alla Sanità\" (Public Health Office), and became a check point for all goods and people coming to and going from Venice by ship. In 1793, there were several cases of the plague on two ships, and consequently the island was transformed into a temporary confinement station for the ill (\"lazaretto\"); this role became permanent in 1805, under the rule of Napoleon Bonaparte, who also had the old church of San Vitale destroyed; the old bell-tower was converted into a lighthouse. The \"lazaretto\" was closed in 1814. The island was used as a quarantine station from 1793 until 1814. In 1922 the existing buildings were converted into an asylum for the mentally ill and later used as a nursing home/long-term care facility, until its closure in 1968. Afterwards, the island was briefly used for agriculture and then completely abandoned. In 2014 the Italian state auctioned a 99-year lease of Poveglia, which would remain state property, to raise revenue, hoping that the buyer would redevelop the hospital into a luxury hotel. The highest bid was from Italian businessman Luigi Brugnaro, (€513,000); he planned to invest €20 million euros in a restoration plan. The lease did not proceed because his project was judged not to meet all the conditions. Other sources suggested that the deal was annulled because the bid was too low. Brugnaro initially fought the cancellation of the lease, but after he became mayor of Venice, he renounced any intentions to the island.

The tower was re-used as a lighthouse. The existence of an asylum on Poveglia seems to be confirmed by a sign for \"Reparto Psichiatria\" (Psychiatric Department) still visible among the derelict buildings, as photographed by Ransom Riggs in his May 2010 photo-essay documenting his visit to Poveglia. However, there seems to be no evidence of an alleged prison. A bridge connects the island on which the buildings stand with the island that was given over to trees and fields. The octagonal fort is on a third, separate island, next to the island with the buildings, but unconnected to it. The fort itself today consists solely of an earthen rampart faced on the outside with brick. The island contains one or more plague pits.

The island was sealed off and used to host people with infectious diseases, leading to legends of terminally ill Venetians waiting to die before their ghosts returned to haunt the island. A doctor allegedly experimented on patients with crude lobotomies. According to various reports, most recently by the Travel Channel, the doctor jumped from the bell tower in the 1930s after claiming he had been driven mad by ghosts. He later died. Decades later, nearby residents claimed to still hear the bell, although it was removed many years earlier. That report, titled \"Haunted History\", also states that some restoration work had started recently but that \"abruptly stopped without explanation\". The island has been featured on the paranormal shows \"Ghost Adventures\" and \"Scariest Places on Earth\". Poveglia was also featured in the \"Alex Rider\" series by Anthony Horowitz as \"Malagosto\", the main assassin training centre for SCORPIA. A dark Polish graphic novel by Roman Pietraszko (art) and Maciej Kur (script) titled \"Żyjesz?\" (\"Are you alive?\") is set on the island of Poveglia during the Plague and focuses on a sick girl and a boy trying to escape from the island while being hunted down by the plague doctors.

The island is owned in the 18th century by a rich nobleman and alchemist, who finds a way to shield his palazzo, himself, and his guests from the ravages of time to repeat the same day over and over. The narrator visits the island as a boy and later as an adult, where (like Poveglia) it has been long since abandoned with a reputation of being haunted. Linda Medley's graphic novel \"Castle Waiting\" refers to Poveglia as 'The Island of No Return'. The character Dr. Fell was driven mad attempting to treat the plague victims. Laurie R. King's novel \"Island of the Mad\" features Poveglia as the hiding place of a group of women who wish to escape the rising Fascist regime, and use the ghost stories of the island as cover to keep unwanted visitors away. David Nathaniel Holcomb’s gothic fantasy novels “Grim’s Squad” features Poveglia as Grim’s Squad’s home base. In the novel \"The Dark Temple\" by R.D.

In the post-World War II years, Keynes's policy ideas were widely accepted. For the first time, governments prepared good quality economic statistics on an ongoing basis and a theory that told them what to do. In this era of New Deal liberalism and social democracy, most western capitalist countries enjoyed low, stable unemployment and modest inflation.", "section_level": 1}, {"title": "IS–LM model (investment saving–liquidity preference money supply).", "content": "It was with John Hicks that Keynesian economics produced a clear model which policy-makers could use to attempt to understand and control economic activity. This model, the IS–LM model, is nearly as influential as Keynes' original analysis in determining actual policy and economics education. It relates aggregate demand and employment to three exogenous quantities, i.e. the amount of money in circulation, the government budget and the state of business expectations. This model was very popular with economists after World War II because it could be understood in terms of general equilibrium theory. This encouraged a much more static vision of macroeconomics than that described above.", "section_level": 2}, {"title": "Phillips curve's successes and collapse.", "content": "The second main part of a Keynesian policy-maker's theoretical apparatus was the Phillips curve. This curve, which was more of an empirical observation than a theory, indicated that increased employment over unemployment implied increased inflation. Keynes had only predicted that increase employment would cause a higher price, not a higher inflation rate. Thus the economist could use the IS–LM model to predict, for example, that an increase in the money supply would raise output and employment—and then use the Phillips curve to predict an increase in inflation. The strength of Keynesianism's influence can be seen by the wave of economists which began in the late 1940s with Milton Friedman- Milton Friedman rejected Keynesian teaching this is misleading. Instead of rejecting macro-measurements and macro-models of the economy, they embraced the techniques of treating the entire economy as having a supply and demand equilibrium, but unlike the Keynesians—they argued that \"crowding out\" effects would hobble or deprive fiscal policy of its positive effect. Instead, the focus should be on monetary policy, which was largely ignored by early Keynesians. The monetarist critique pushed Keynesians toward a more balanced view of monetary policy and inspired a wave of revisions to Keynesian theory. Through the 1950s, moderate degrees of government demand leading industrial development and use of fiscal and monetary counter-cyclical policies continued and reached a peak in the \"go go\" 1960s, where it seemed to many Keynesians that prosperity was now permanent. However, with the oil shock of 1973 and the economic problems of the 1970s, modern liberal economics began to fall out of favor. During this time, many economies experienced \"stagflation\" : high and rising unemployment, coupled with high and rising inflation, contradicting the Phillips curve's prediction. This stagflation meant that both expansionary (anti-recession) and contractionary (anti-inflation) policies had to be applied simultaneously, a clear impossibility. This dilemma led to the rise of ideas based upon more classical analysis, including monetarism, supply-side economics and new classical economics. This produced a \"policy bind\" and the collapse of the Keynesian consensus on the economy.", "section_level": 2}, {"title": "New Keynesian economics.", "content": "Through the 1980s, Keynesian macroeconomics fell out of fashion as a policy tool and as a field of study. Instead, it was felt that combining economics with behavioral science, game theory and monetary theory were more important areas of study. On the policy level, it was the era of Margaret Thatcher and Ronald Reagan, who advocated slashing the size of the government sector. However, beginning in the late 1980s economics began shifting back to a study of macro-economics and policy makers began to look for means of managing the global financial network, which was increasingly interlinked. In the 1990s, the \"uncoupling\" of money supply and inflation caused an increasing questioning of the original form of monetarism. The repeated failures of \"big bang\" marketization in the former Soviet Bloc have encouraged the recent revival in Keynesian ideas, with particular emphasis on giving the Keynesian macroeconomic analysis theoretically sound foundations in microeconomics. These theories have been called new Keynesian economics. The heart of the new Keynesian view rests on microeconomic models that indicate that nominal wages and prices are \"sticky\", i.e. do not change easily or quickly with changes in supply and demand, so that quantity adjustment prevails. According to economist Paul Krugman, this \"works beautifully in practice but very badly in theory\". This integration is further spurred by work of other economists which questions rational decision-making in a perfect information environment as a necessity for micro-economic theory. Imperfect decision making such as that investigated by Joseph Stiglitz underlines the importance of management of risk in the economy. New classical economics relied on the theory of rational expectations to reject Keynesian economics. Most well-known is the Lucas critique by Robert Lucas, who argues that rational expectations will defeat any monetary or fiscal policy. However, new Keynesians argue that this critique only works if the economy has a unique equilibrium at full employment. Price stickiness means that there are a variety of possible equilibria in the short run, so that rational expectations models do not produce any simple result. Some macroeconomists have returned to the IS–LM model and the Phillips curve as a first approximation of how an economy works. New versions of the Phillips curve, such as the triangle model, allow for stagflation since the curve can shift due to supply shocks or changes in built-in inflation. In the 1990s, the original ideas of \"full employment\" had been replaced by the NAIRU theory, sometimes called the \"natural rate of unemployment\". This theory pointed to the dangers of getting unemployment too low because accelerating inflation can result, but it is unclear exactly what the value of the NAIRU is—or whether it really exists or not.", "section_level": 1}], "src_summary": "Neo-Keynesian economics is a school of macroeconomic thought that was developed in the post-war period from the writings of John Maynard Keynes.

Notice that the Pythagorean comma (PC) and the syntonic comma (SC) are basic intervals that can be used as yardsticks to define some of the other commas. For instance, the difference between them is a small comma called schisma. A schisma is not audible in many contexts, as its size is narrower than the smallest audible difference between tones (which is around six cents, also known as just noticeable difference, or JND). Many other commas have been enumerated and named by microtonalists The syntonic comma has a crucial role in the history of music. It is the amount by which some of the notes produced in Pythagorean tuning were flattened or sharpened to produce just minor and major thirds. In Pythagorean tuning, the only highly consonant intervals were the perfect fifth and its inversion, the perfect fourth. The Pythagorean major third (81:64) and minor third (32:27) were dissonant, and this prevented musicians from freely using triads and chords, forcing them to write music with relatively simple texture. In late Middle Ages, musicians realized that by slightly tempering the pitch of some notes, the Pythagorean thirds could be made consonant. For instance, if you decrease by a syntonic comma (81:80) the frequency of E, C–E (a major third), and E–G (a minor third) become just. Namely, C–E is flattened to a justly intonated ratio of and at the same time E–G is sharpened to the just ratio of This brought to the creation of a new tuning system, known as quarter-comma meantone, which permitted the full development of music with complex texture, such as polyphonic music, or melodies with instrumental accompaniment.

This method was called the extended Helmholtz-Ellis JI pitch notation. Sabat and Schweinitz take the \"conventional\" flats, naturals and sharps as a Pythagorean series of perfect fifths. Thus, a series of perfect fifths beginning with F proceeds and so on. The advantage for musicians is that conventional reading of the basic fourths and fifths remains familiar. Such an approach has also been advocated by Daniel James Wolf and by Joe Monzo, who refers to it by the acronym HEWM (Helmholtz-Ellis-Wolf-Monzo). In the Sabat-Schweinitz design, syntonic commas are marked by arrows attached to the flat, natural or sharp sign, septimal commas using Giuseppe Tartini's symbol, and undecimal quartertones using the common practice quartertone signs (a single cross and backwards flat). For higher primes, additional signs have been designed. To facilitate quick estimation of pitches, cents indications may be added (downward deviations below and upward deviations above the respective accidental). The convention used is that the cents written refer to the tempered pitch implied by the flat, natural, or sharp sign and the note name. One of the great advantages of any such a notation is that it allows the natural harmonic series to be precisely notated. A complete legend and fonts for the notation (see samples) are open source and available from Plainsound Music Edition. Thus a Pythagorean scale is, while a just scale is. Composer Ben Johnston uses a \"−\" as an accidental to indicate a note is lowered a syntonic comma, or a \"+\" to indicate a note is raised a syntonic comma; however, Johnston's \"basic scale\" (the plain nominals ) is tuned to just-intonation and thus already includes the syntonic comma.

A comma can be viewed as the distance between two musical intervals. When a given comma is tempered out in a tuning system, the ability to distinguish between those two intervals in that tuning is eliminated. For example, the difference between the diatonic semitone and chromatic semitone is called the diesis. The widely used 12-tone equal temperament \"tempers out\" the diesis, and thus does not distinguish between the two different types of semitones. On the other hand, 19-tone equal temperament does not temper out this comma, and thus it distinguishes between the two semitones. Examples: The following table lists the number of steps used that correspond various just intervals in various tuning systems. Zeros indicate commas. The comma can also be considered as the interval that remains after a full circle of intervals. The Pythagorean comma, for instance, is the difference obtained, say, between A and G after a circle of twelve just fifths. A circle of three just major thirds, such as A–C–E–G, produces the \"small diesis\" 125/128 (41,1 cent) between G and A. A circle of four just minor thirds, such as G–B–D–F–A, produces an interval of 648/625 between A and G. Etc.

Its mass is estimated to be approximately a third that of the Sun, and it is the 89th closest known star system to the Sun.

However, a red dwarf such as Gliese 581 radiates primarily in the near infrared, with peak emission at a wavelength of roughly 830 nm (estimated using Wien's displacement law, which assumes the star radiates as a black body), so such an estimate will underestimate the star's total luminosity.

After his return he filled various educational offices, and took his doctorate with two theses, \"Quid Vestae cultus in institutis veterum privatis publicisque valuerit\" and \"Polybe, ou la Grèce conquise par les Romains\" (1858). In these works his distinctive qualities were already revealed. His minute knowledge of the language of the Greek and Roman institutions, coupled with his low estimate of the conclusions of contemporary scholars, led him to go directly to the original texts, which he read without political or religious bias. When, however, he had succeeded in extracting from the sources a general idea that seemed to him clear and simple, he attached himself to it as if to the truth itself. From 1860 to 1870 he was professor of history at the faculty of letters at Strasbourg, where he had a brilliant career as a teacher, but never yielded to the influence exercised by the German universities in the field of classical and Germanic antiquities. It was at Strasbourg that he published his remarkable volume \"La Cité antique\" (1864), in which he showed forcibly the part played by religion in the political and social evolution of Greece and Rome. The book was so consistent throughout, so full of ingenious ideas, and written in so striking a style, that it ranks as one of the masterpieces of the French language in the 19th century. By this literary merit Fustel set little store, but he clung tenaciously to his theories. When he revised the book in 1875, his modifications were very slight, and it is conceivable that, had he recast it, as he often expressed the desire to do in the last years of his life, he would not have abandoned any part of his fundamental thesis. Fustel de Coulanges was appointed to a lectureship at the École Normale Supérieure in February 1870, to a professorship at the Paris faculty of letters in 1875, and to the chair of medieval history created for him at the Sorbonne in 1878, he applied himself to the study of the political institutions of ancient France. The invasion of France by the German armies during the Franco-Prussian War attracted his attention to the Germanic invasions under the Roman Empire. Pursuing the theory of JB Dubos, but also transforming it, he maintained that those invasions were not marked by the violent and destructive character usually attributed to them; that the penetration of the German barbarians into Gaul was a slow process; that the Germans submitted to the imperial administration; that the political institutions of the Merovingians had their origins in the Roman laws at least as much as, if not more than, in German usages; and, consequently, that there was no conquest of Gaul by the Germans. This thesis he sustained in his \"Histoire des institutions politiques de l'ancienne France\", the first volume of which appeared in 1874. It was the author's original intention to complete this work in four volumes, but as the first volume was keenly attacked in Germany as well as in France, Fustel was forced in self-defence to recast the book entirely. He re-examined all the texts and wrote a number of dissertations, which were dominated by his general idea and characterized by a total disregard for the results of such historical disciplines as diplomatic. From this crucible issued an entirely new work, less well arranged than the original, but rich in facts and critical comments. The first volume was expanded into three volumes, \"La Gaule romaine\" (1891), \"L'Invasion germanique et la fin de l'empire\" (1891) and \"La Monarchie franque\" (1888), followed by three other volumes, \"L'Alleu et le domaine rural pendant l'époque mérovingienne\" (1889), \"Les Origines du système féodal: le bénéfice et le patronat...\" (1890) and \"Les Transformations de la royauté pendant l'époque carolingienne\" (1892). Thus, in six volumes, he had carried the work no farther than the Carolingian period. The dissertations not embodied in his work were collected by himself and (after his death) by his pupil, Camille Jullian, and published as volumes of miscellanies: \"Recherches sur quelques problèmes d'Histoire\" (1885), dealing with the Roman colonate, the land system in Normandy; the Germanic mark, and the judiciary organization in the kingdom of the Franks; \"Nouvelles recherches sur quelques problèmes d'histoire\" (1891); and \"Questions historiques\" (1893), which contains his paper on Chios and his thesis on Polybius. His life was devoted almost entirely to his teaching and his books. In 1875, he was elected member of the Académie des Sciences Morales et Politiques, and in 1880 reluctantly accepted the post of director of the École Normale. Without intervening personally in French politics, he took a keen interest in the questions of administration and social reorganization arising from the fall of the imperialist régime and the disasters of the war. He wished the institutions of the present to approximate more closely to those of the past, and devised for the new French constitution a body of reforms which reflected the opinions he had formed upon the democracy at Rome and in ancient France.

His father was Antonín Bartholomäus Koželuh, a shoemaker. He was baptised Jan Antonín, but by 1773 he had adopted the name Leopold to avoid confusion with his elder cousin, the composer Jan Antonín Koželuh. He also Germanised his surname to Koželuch. After starting his musical education in Velvary, Koželuch moved to Prague where he studied with his cousin and František Xaver Dušek, the latter teaching him in the keyboard and composition. From 1771 to 1778 Koželuch wrote ballets and pantomimes which were performed in Prague. The success of these works led him to abandon plans to study law in favour of a musical career. He moved to Vienna for this purpose in 1778, where he quickly established himself as a pianist, albeit one who did not perform in public, composer and teacher. Pianist Kemp English observes that in Vienna Koželuch \"found himself in the right place at the right time\", and was able to advance his career there with carefully cultivated connections. He composed a cantata for the death of Maria Theresa in 1780. His pupils would include Maria Theresia Paradis, Archduchess Elisabeth of Württemberg and Archduchess Marie Louise. His appointment to teach Archduchess Elizabeth was an official court position, succeeding Georg Christoph Wagenseil. In 1781 Wolfgang Amadeus Mozart resigned his appointment as court organist in Salzburg following a quarrel with his employer, the Archbishop of Salzburg. The Archbishop offered the position to Koželuch, but Koželuch refused, later expressing concerns to a friend that he might too have fallen victim to what he saw as Mozart's ill-treatment. In 1784 Koželuch expanded into publishing, and soon formed his own firm, Musikalisches Magazin, which would later come under the management of his brother Antonín Tomáš. Koželuch would use the firm, in combination with overseas partners, to publish many of his compositions. By 1790, a time at which Mozart and Joseph Haydn were at the height of their careers, Koželuch's reputation was such as to move Ernst Ludwig Gerber to say the following of his status within Europe: \"Leopold Kozeluch is without question with young and old the generally most loved among our living composers, and this with justification\". Koželuch's esteem in royal circles grew again in 1791, when he composed a well-received cantata commissioned for the coronation of Emperor Leopold II in Prague. Mozart composed \"La clemenza di Tito\" for the same occasion. Mozart's death later in the year afforded Koželuch another opportunity: Emperor Franz II offered him Mozart's positions in his court, \"Kammer Kapellmeister\" (music director) and \"Hofmusik Compositor\" (composer), and at double Mozart's salary. Koželuch would remain in the positions until his death. Koželuch joined a masonic lodge in 1791, marking another coincidence between his career and Mozart's and serving to advance himself further within Viennese society. Koželuch's compositional output declined after the turn of the century as he focused on his court duties, teaching, and the lucrative work of arranging Scottish, Irish and Welsh folk songs for the publisher George Thomson. William Crotch reflected on Koželuch's reputation in a lecture in 1806, remarking that he had \"sunk in unmerited neglect\" while Mozart's reputation had enjoyed posthumous growth. In 1809, Ludwig van Beethoven, a frequent disparager of rival composers, would write to Thomson referring to Koželuch as \"Miserabilis\". Koželuch died on 7 May 1818. His daughter, Catherina Cibbini-Kozeluch, became a prominent pianist and composer based in Vienna.", "section_level": 1}, {"title": "Works.", "content": "Koželuch left around 400 compositions.

Among his music there are also operas and works for ballet, which—with the exception of one opera —have yet to be heard in recent years.

Christopher Hogwood argues that Koželuch's keyboard sonatas, especially those which open in minor keys, \"substantially anticipated... the tragic-pathetic manner\" of Beethoven and Schubert, and that in them he \"created the internationally praised \"cantabile\" idiom\". Hogwood further states that \"Koželuch's sonatas are, in the true sense, 'classics'—that is to say,'models for imitation and study'—and display to perfection precisely those features that theorists required of a sonata at the end of the 18th century.\" The oeuvre of sonatas spans almost the entirety of Koželuch's career: the first was composed in 1773; the final three date from after 1810. The sonatas cater for different purposes. Some are exhibitionist works; some are simpler; some are cast in a Romantic style that foreshadows Beethoven. In the third category, Koželuch was composing slow minor-key introductions to sonatas as much as 17 years before Beethoven composed his Piano Sonata No. 8 (\"Pathetique\"), while neither Mozart nor Haydn ever did so. Koželuch's composed his sonatas to be played on the newly emerging fortepiano rather than the harpsichord. The popularity of the sonatas in turn helped to make the fortepiano fashionable. Twenty-two Koželuch keyboard concertos survive. The musicologist Richard Wigmore argues that they \"conspicuously lack the melodic abundance, rich woodwind colouring and operatic-style dialogues of Mozart's great Viennese concertos\", but nonetheless \"beguile with their limpid grace, their sparkling keyboard writing (often in just two parts), and their sense of proportion.\" Most are scored only for strings, oboes, horns and soloist—sparser than Mozart's scoring of his contemporaneous concertos—suggesting that the works were intended for small-scale performances.", "section_level": 2}, {"title": "Chamber.", "content": "Koželuch's chamber music, especially his output from the 1790s, is among the more advanced of his works, often foreshadowing the expressionism of Beethoven.

Badley argues that Koželuch's symphonies are influenced by those of his Prague teacher František Xaver Dušek in their orchestration and thematic organisation. Almost all of Koželuch's choral works, including cantatas and five of his six operas, have been lost.

Elected to the Supreme Council of Georgia the same year, he was closely associated with Zviad Gamsakhurdia, a Soviet-era dissident who went on to become the chairman of the Presidium of the Supreme Council and eventually the President of Georgia in 1991. In December 1990, Gamsakhurdia decreed the creation of the National Guard of Georgia and appointed Kitovani as its head. However, the two men collided in August 1991, when Gamsakhurdia sacked him as National Guard commander.

Ioseliani, as well as Gamsakhurdia’s supporters and some independent observers, claimed that Kitovani hired some Soviet/Russian troops stationed in Tbilisi to join the attack on the government. On January 2, 1992, the deposition of Gamsakhurdia and the formation of the Military Council had been announced with Kitovani and Ioseliani as its leaders. Gamsakhurdia had been forced into exile by January 6, 1992, and the coup leaders invited the former Soviet foreign minister Eduard Shevardnadze to head the post-coup provisional government – the State Council – in March 1992. As a result of the power-sharing arrangement that was eventually struck between Ioseliani, Kitovani, Sigua and Shevardnadze, Kitovani remained the commander of the National Guard and retained a considerable influence on decision making. In May 1992, Shevardnadze appointed Kitovani Minister of Defence and Deputy Prime Minister in an effort to bring the National Guard under central control. However, both Kitovani and Ioseliani were reluctant to concede power to Shevardnadze and tended to engage in unilateral actions, and in doing so frequently conflicted with each other. The first and most obvious of such actions was taken by Kitovani during a planned military operation against Gamsakhurdia’s supporters who had formed pockets of armed resistance in western Georgia and had taken Georgian government officials hostage. On the night of August 13, 1992, Kitovani’s force entered the autonomous republic of Abkhazia, whose leadership had taken a series of steps towards secession from Georgia, in order to establish control over the region’s railways sabotaged by Gamsakhurdia's loyal militias. Although this operation and show of force resulted in the eventual release of the hostages, Kitovani, acting most probably on his own initiative, proceeded towards Abkhazia’s capital of Sukhumi and forced the Abkhaz leaders into flight. Shevardnadze failed to have Kitovani’s force withdrawn from Abkhazia and the country became involved in a thirteen-month-long war which would end in Georgia’s loss of control over most of Abkhazia. Another version of these events, often quoted in Georgia, says that Russia, while supporting the Abkhaz, also instigated Kitovani to trigger the conflict and perhaps even promised support for his leadership ambitions in Georgia after a successful operation. Later, Shevardnadze would accuse Kitovani of provoking an armed conflict in Abkhazia, claiming that Kitovani disavowed his order and advance with his military to Sukhumi. Kitovani however blamed Shevardnadze for preventing him from following up an offensive on Sukhumi with an attack on the Abkhaz stronghold in Gudauta, home to a Russian military base which supplied the secessionist forces with instructors and munitions.

Kitovani stood as a candidate in Georgia's parliamentary elections of October 11, 1992 and was elected in the single-mandate constituency of Bolnisi. In the aftermath of the elections, Shevardnadze attempted to replace him as Minister of Defence with a professional soldier, General Anatoli Kamkamidze, but was unable to do so. Amid persistent rumors that he was planning a new military coup, Kitovani was finally forced into resignation in May 1993 – though a protégé, Gia Karkarashvili, was named as his replacement, and he was able to retain some of his power – partly, according to widespread rumours in Tbilisi, through his control over Georgia’s \"energy mafia\" and his \"special relationship\" with Russian defence minister Pavel Grachev. However, Shevardnadze was able to exploit the military setback in Abkhazia to embark on a crackdown on the paramilitary groups and ultimately their leaders. After the pro-Gamsakhurdia rebellion had been quashed with Russian aid by December 1993, Shevardnadze was able to increasingly consolidate his power and deprive both Kitovani and Ioseliani of influence over national security policy. After spending some time in Russia, Kitovani returned to Tbilisi and, together with Tengiz Sigua and Boris Kakubava, leader of a faction of ethnic Georgian IDPs from Abkhazia, founded the National Front for the Liberation of Abkhazia in the autumn of 1994.

Although double stars had been studied earlier by William Herschel and John Herschel and Sir James South, Struve outdid any previous efforts. He discovered a very large number of double stars and in 1827 published his double star catalogue \"Catalogus novus stellarum duplicium\". Stars of his catalogue are sometimes indicated by the Greek letter sigma, Σ. Thus, 61 Cygni is also designated as Σ2758. Since most double stars are true binary stars rather than mere optical doubles (as William Herschel had been the first to discover), they orbit around one another's barycenter and slowly change position over the years. Thus Struve made micrometric measurements of 2714 double stars from 1824 to 1837 and published these in his work \"Stellarum duplicium et multiplicium mensurae micrometricae\". Struve carefully measured the \"constant of aberration\" in 1843. He was also the first to measure the parallax of a star Vega, although Friedrich Bessel had been the first to measure the parallax of a star (61 Cygni). In an 1847 work, \"Etudes d'Astronomie Stellaire: Sur la voie lactee et sur la distance des etoiles fixes,\" Struve was one of the first astronomers to identify the effects of interstellar extinction (though he provided no mechanism to explain the effect). His estimate of the average rate of visual extinction, 1 mag per kpc, is remarkably close to modern estimates (0.7–1.0 mag per kpc). He was also interested in geodetic surveying, and in 1831 published \"Beschreibung der Breitengradmessung in den Ostseeprovinzen Russlands\".

At the Academy, Say began his work on what he would publish as \"American Entomology\". To collect insects, he made numerous expeditions to frontier areas, risking American Indian attacks and hazards of traveling in wild countryside. In 1818, Say accompanied his friend William Maclure, then the ANSP president and father of American geology; Gerhard Troost, a geologist; and other members of the Academy on a geological expedition to the off-shore islands of Georgia and Florida, then a Spanish colony. In 1819–20, Major Stephen Harriman Long led an exploration to the Rocky Mountains and the tributaries of the Missouri River, with Say as zoologist.

In 1823, Say served as chief zoologist in Long's expedition to the headwaters of the Mississippi River. He traveled on the \"Boatload of Knowledge\" to the New Harmony Settlement in Indiana (1826–34), a utopian society experiment founded by Robert Owen.

He was the tenth of eleven children. From 1910 to 1913 he studied in Vilnius at a small art academy. In 1913, with his friends Pinchus Kremegne (1890–1981) and Michel Kikoine (1892–1968), he emigrated to Paris, where he studied at the École des Beaux-Arts under Fernand Cormon. He soon developed a highly personal vision and painting technique. For a time, he and his friends lived at La Ruche, a residence for struggling artists in Montparnasse where he became friends with Amedeo Modigliani (1884–1920). Modigliani painted Soutine's portrait several times, most famously in 1917, on a door of an apartment belonging to Léopold Zborowski (1889–1932), who was their art dealer. Zborowski supported Soutine through World War I, taking the struggling artist with him to Nice to escape the possible German invasion of Paris. After the war Paul Guillaume, a highly influential art dealer, began to champion Soutine's work. In 1923, in a showing arranged by Guillaume, the prominent American collector Albert C. Barnes (1872–1951), bought 60 of Soutine's paintings on the spot. Soutine, who had been virtually penniless in his years in Paris, immediately took the money, ran into the street, hailed a Paris taxi, and ordered the driver to take him to Nice, on the French Riviera, more than 400 miles away. Soutine once horrified his neighbours by keeping an animal carcass in his studio so that he could paint it (\"Carcass of Beef\"). The stench drove them to send for the police, whom Soutine promptly lectured on the relative importance of art over hygiene. There's a story that Marc Chagall saw the blood from the carcass leak out onto the corridor outside Soutine's room, and rushed out screaming, 'Someone has killed Soutine.' Soutine painted 10 works in this series, which have since become his most well-known. His carcass paintings were inspired by Rembrandt's still life of the same subject, \"Slaughtered Ox\", which he discovered while studying the Old Masters in the Louvre. Soutine produced the majority of his works from 1920 to 1929. From 1930 to 1935, the interior designer Madeleine Castaing and her husband welcomed him to their summer home, the mansion of Lèves, becoming his patrons, so that Soutine could hold his first exhibition in Chicago in 1935. He seldom showed his works, but he did take part in the important exhibition \"The Origins and Development of International Independent Art\" held at the Galerie nationale du Jeu de Paume in 1937 in Paris, where he was at last hailed as a great painter. Soon afterwards France was invaded by German troops. As a Jew, Soutine had to escape from the French capital and hide in order to avoid arrest by the Gestapo. He moved from one place to another and was sometimes forced to seek shelter in forests, sleeping outdoors. Suffering from a stomach ulcer and bleeding badly, he left a safe hiding place for Paris in order to undergo emergency surgery, which failed to save his life.

Roenick, a former Marine, is deskbound and abusing alcohol and prescription drugs, blaming himself for a botched undercover operation eight months prior that resulted in the deaths of two members of his team. Psychiatrist Alexandra Sabian is treating a reluctant and dismissive Roenick at the station. Crime lord Marion Bishop is arrested when he kills an undercover police officer. Two Sheriff's Department Deputies are transferring Bishop with three other criminals: addict ex-lawyer Beck, petty crook Anna, and counterfeiter Smiley. When a raging snowstorm shuts down the roads, the transport bus is directed to the nearby Precinct 13. Masked gunmen cut off the Precinct's communication, attack the station, kill the Deputies and demand Bishop be handed over to them. The lawmen believe the attackers are Bishop's men. When they kill one of the attackers, they discover he is from a crew of undercover officers led by Captain Marcus Duvall of Precinct 21. Rather than trying to avenge the cop that Bishop murdered, they are actually Bishop's crooked partners in crime. Bishop balked when Duvall and his crew demanded a larger cut, so Duvall and his men (starting with the original dead cop) are trying to kill Bishop before he can testify about their involvement. Heavily outnumbered and outgunned, Roenick sets free and arms the prisoners to bolster the defense of the station. Roenick and Bishop forge an uneasy truce between cops and criminals, as both groups know they will be killed by Duvall to protect his secret. Their combined efforts repel several more attacks. Off-duty cop Capra, who has been partying and wants to make a move on Iris, returns to the station. Duvall's men shoot at him, but he makes it into the Precinct. Beck believes that Capra is a plant for Duvall, but Roenick vouches for him. Beck doesn't believe him and tries to attempt a mutiny, but Bishop sides with Roenick and forcefully reminds Beck that Roenick is in charge. With Capra's vehicle outside the front door, Beck and Smiley secretly plan to make a break for it. At the same time, the rest of the defenders are also planning to use the vehicle, with Anna and Dr. Sabian volunteering to be the driver and \"gunman\" in an effort to get help. Beck and Smiley happen to sneak out first, both getting killed by Duvall's men, inadvertently providing a distraction for Anna and Sabian to get away. Duvall had anticipated this and hidden Kahane, his second in command, in the back seat. Kahane kills Anna, then Duvall kills Sabian after she refuses to give intel on Precinct 13's defenders. With only five defenders left alive, Roenick and Bishop decide to take action instead of waiting for another attack. When someone inside unlocks the back door, they suspect Capra to be a mole for Duvall and put him in handcuffs. The storm eases just enough to allow Duvall to call in some corrupt SWAT officers by helicopter, who land on the roof of Precinct 13. The defenders set fire to the station to cover their escape and flee through a utilities tunnel underneath the building. Emerging from the tunnel, they find themselves surrounded by the corrupt policemen. The real Duvall insider is revealed to be O'Shea, and Duvall prepares to execute the rest. Bishop secretly plants a flash bang grenade on O'Shea, killing him. In the confusion Iris and Capra flee in Duvall's truck. When Kahane shoots out their tires and moves in for the kill, Iris manages to kill him with his own knife. Roenick and Bishop are chased into a small urban forest, where they work together to survive the final confrontation with Duvall and his remaining men. Duvall wounds both of them before Roenick finally manages to kill Duvall. Bishop, more mobile of the two, takes Roenick's gun and flees, with Roenick promising to personally arrest him in the future. When Iris arrives with police, fire and medical services, Roenick claims that only he and the dead cops are present – giving Bishop a head start. Roenick and Iris leave the forest as the sun rises.

S. probably came from a background and training as a goldsmith, rather than as a painter. He sometimes used goldsmith punches in his prints (for example, to make the circles on the borders of the clothes in the \"Delilah\" print above) and some works are clearly designs for metalwork. He was the first printmaker to sign his prints with an engraved monogram, which was standard practice on significant pieces of metalwork. He engraved two images of Saint Eligius, the patron-saint of goldsmiths. He liked to fill his engravings with decorative detail, sometimes overloading the composition, and only slowly does a sense of volume or recession develop in his work. Since his earliest prints show a practiced use of the burin, he is presumed to have worked as a goldsmith for some years before beginning printmaking. His date of birth is estimated on this basis. His level of production of prints probably means that he worked on these only during his later years.

S. into three stylistic periods: around 1450, up to 1460, and after 1460. During the second period he made significant technical developments. Firstly, deeper incisions with the burin, which allowed more impressions to be taken from each plate, although the number still may have been limited to about sixty or so, before wear on the plate began to show and reworking was necessary for it to be used again. His use of hatching (parallel lines) and cross-hatching to depict shading and volume, steadily grew more sophisticated and his figure-drawing became more confident, sometimes overconfident. Many figures of this period have contorted poses even when at rest. In works from the third period, his figures are more relaxed and flat surfaces are given prominence in the compositions. Many faces of his subjects have a rather pudding-like appearance, and are overly-large for their bodies, which diminishes the quality of otherwise, fine works. Much of his work still has great charm, and the secular and comic subjects he engraved are rarely found in the surviving painting of the period. Lehrs catalogues three hundred and eighteen engravings by E. S. and of these, ninety-five are unique, and fifty exist in only two impressions (copies).

He received a humanist training and participated in knightly tournaments. His father, George, was King of Bohemia, but this crown was not heritable. George persuaded Emperor Frederick III in 1459 to appoint his eldest son Victor to Imperial Count. In 1462, Frederick also appointed Henry the Younger and his elder brother Henry the Elder to Imperial Count. Earlier, George had appointed his three sons Count of Glatz and enfeoffed them with the County of Glatz and the Duchy of Münsterberg. In 1465 he also enfeoffed them with the Duchy of Opava, which he had acquired in 1464. In 1471, Henry the Younger married Catherine, the daughter of William III, Landgrave of Thuringia. His father died soon thereafter. Although Henry had stood at his father's side politically and religiously when he was young, he then turned to the Catholic faith. George's successor King Vladislas II undertook to protect George's sons and to take over their debts. George's sons initially ruled his territories together, but in 1472, the inheritance was split. Henry the Younger received Poděbrady, Kostomlaty nad Labem and possessions in Silesia. From his mother he inherited Lichnice Castle, Melnik and Teplice. At the state convention of Benešov in 1472, Henry was elected as the provincial administrator on the recommendation of his mother, who also took part. Unlike his mother, however, he sided with the Hungarian king, Matthias Corvinus. The reason for this was probably that Vladislas repaid his debts only slowly, while Matthias Corvinus did so without hesitation. In 1475, Henry sold the Lordship of Kolín, which he had received from his older brother Victor, for ducats to Matthias Corvinus, who stationed his Hungarian occupation troops there. After Henry appointed the Corvinus supported and despot Racek Kocovský as the administrator of Konopiště, Vladislas's supporters aligned with those of Matthias Corvinus. In 1478 it came to a reconciliation between Henry and Vladislas under the Treaty of Brno. Henry prepared the agreement to appointment Vladislas as King of Bohemia and played a significant role in resolving various religious and legal disputes Bohemia. In 1488 he chose the side of the Silesian princes who rebelled against Matthias Corvinus. After the rebellion was suppressed, he had to assign his inherited possessions of Poděbrady and Kostomlaty to John Corvinus, an illegitimate son of Matthias Corvinus. Henry was, however, granted a life interest in these possessions. Henry the Younger died in 1492 at the Poděbrady Castle.

She was christened on 27 October 1766 at St James's Palace by the Archbishop of Canterbury, Thomas Secker, and her godparents were her paternal aunts Caroline Matilda and Louisa and Caroline Matilda's husband King Christian VII of Denmark. The Duke of Portland, Lord Chamberlain, and the Dowager Countess of Effingham, stood proxy for the King and Queen of Denmark. Charlotte was officially designated as Princess Royal on 22 June 1789. After the birth of three sons in a row, her parents were delighted to have a Princess in the nursery. Like all of her siblings, Charlotte was inoculated, in her case, in December 1768 along with her brother William. As the eldest daughter of the monarch, Charlotte was assumed to be destined for an important marriage on the continent, and her education was considered to be of the utmost importance, beginning when she was only eighteen months old. Since French was the official language in every European court, the little Princess was given a Frenchwoman to be her tutor, in order that she should have no accent. Her memory was another of her beginning subjects. She was taught to recite little verses and stories, and as a result had an almost uncanny ability to recall detail for the rest of her life. Her early childhood was not all scholarly pursuits. When she was almost three years old, she took place in her first tableau dressed like Columbine, where she danced with her seven-year-old brother George, Prince of Wales. She was not a naturally musical child and later abhorred such displays of children, declaring that they made children vain and self-important. This did not stop her parents from continuing to show her off. In late 1769, she and the Prince of Wales were once again displayed, this time to the public in a \"junior drawing room\" in St James's Palace. Charlotte was dressed in a Roman toga and lay on a sofa. Though this type of thing was common in German courts, it was considered vulgar in England, where in reaction a London mob drove a hearse into the Palace courtyard. Afterward, the Prince of Wales told Lady Mary Coke that the whole event had made Charlotte \"terribly tired\". Wisely, the King and Queen decided to never repeat the experience. Though she was the eldest daughter, Charlotte was constantly compared to her sister Augusta Sophia, only two years younger than she. When Augusta was a month old, Lady Mary Coke called her \"the most beautiful baby I have ever seen\" while Charlotte was \"very plain\". Passing judgment once again three years later, Charlotte was now \"the most sensible agreeable child I ever saw, but in my opinion far from pretty\" while Augusta was still \"rather pretty\". Although the Princess Royal was never as beautiful as her younger sister, she did not share in Augusta's primary flaw: painful shyness, though Charlotte did suffer from a stammer that her attendant Mary Dacres tried to help her young charge overcome. In 1770, the cluster of the three eldest princesses was completed with the birth of Princess Elizabeth, the seventh child. For the time being the family remained comparatively small (there were fifteen royal children in all), and Charlotte was fortunate in having parents who preferred spending time with their numerous children to spending all their time at court and took her education seriously. However, given the frequency with which children were being produced and the troubles that plagued George III's reign, Charlotte's childhood was not as utopian as her parents planned it to be.

Along with her twin, she was baptised at Versailles on 27 April 1737. Henriette was named after her paternal great-great grandmother Henrietta, Duchess of Orleans, with Louis Henri, Duke of Bourbon and Louise Anne de Bourbon as her godparents. As the legitimate daughter of the king, she was a \"fille de France\", but as the younger of the twins, she was referred as \"Madame Seconde\"; as an adult, she became known as \"Madame Henriette\", or only \"Madame\", as the eldest daughter of the king present in Versailles after the marriage of her sister. The eldest children of Louis XV, the twins Élisabeth and Henriette, Marie-Louise, Adélaïde and their brother, the Dauphin of France, were raised in Versailles under the supervision of the Governess of the Children of France, Marie Isabelle de Rohan, \"duchesse de Tallard\", while their younger siblings, Victoire, Sophie, Therese and Louise, were sent to be raised at the Abbey of Fontevraud in June 1738. In 1739, her twin moved to Spain to marry the Infante Philip, a younger son of King Philip V. Henriette was reportedly despondent about being separated from her twin.", "section_level": 2}, {"title": "Adult life.", "content": "One of the reasons why her younger sisters were sent away from Versailles to be raised was the high expense of raising royal French children, who were allowed to participate in court life as well as arrange their own festivities even in childhood; those kept at court participated in court life from the age of twelve. From 1744 onward, Henriette and Adelaide accompanied their father to the Opera in Paris, and from 1746, they hunted with him five days a week. In 1744, Henriette and Adelaide were officially transferred from the royal nursery and the King created their own household, the Household of the \"Mesdames aînées\" ('Elder Mesdames') and appointed two ladies-in-waiting (\"dame pour accompagner Mesdames\"); two years later, they were given their own \"dame d'honneur\". Henriette was considered to be a beauty and prettier than her elder twin. She was described as gentle and melancholic to her temperament, reserved but intensely loyal, and gifted in music. She was evidently the favorite child of her father, and it was said that she had no enemies at court. Despite her beauty, no serious marriage negotiations was ever meade for Henriette. In 1740, Louis François, Prince of Conti took the opportunity to suggest a marriage between himself and Henriette when he became alone with the king during a hunt, explaining that he believed that he could make Henriette happy, and that such a marriage would mean that she would never have to leave her father and France; but the king did not react favorably to the proposal. Henriette reportedly fell mutually in love with her cousin, Louis Philippe, \"duc de Chartres\", the heir to the House of Orléans, and reportedly wished to marry him. The King initially liked the idea, but changed his mind, not wanting the house of Orleans too close to the throne, and the plans were finnally discontinued in 1743, when the duke de Chartres married someone else, and Henriette remained unmarried. Her twin Élisabeth, who was described as ambitious, was not satisfied as the spouse of a prince without a throne; she kept in contact with the French court through correspondence, and had already by 1740 established a net of contacts there to assist her in her ambition to obtain independent power positions for herself and her spouse \"worthy of the birth of both\"; Henriette was one of her most fervent champions in this issue. Otherwise regarded as habitually apathetic about politics, Henriette was reportedly passionately devoted to working for the political ambition of her twin, as was her younger sister Adelaide and her sister-in-law Infanta Maria Teresa Rafaela of Spain; the powerful Noailles and Maurepas allied with the queen to achieve the same, and the French ambassador at Madrid, Monseigneur Vaurdal, Archbishop of Rheims. Henriette, as well as her siblings, disliked their father's extramarital liaisons because they caused their father to neglect their mother, and their discontent with their father's adultery was directed toward his mistresses, notably Madame de Pompadour, who from 1745 onward was their father's official mistress at court and influential upon the affairs of state. With her brother, the Dauphin Louis, and her sister, \"Madame Adélaïde\", she called the powerful mistress, \"Maman Putain\" (\"Mother Whore\"). When Louise Élisabeth returned from Parma for a year-long visit to Versailles in 1748, she and \"Madame de Pompadour\" became close friends, which led to a temporary estrangement between the sisters. In 1747, her brother Louis was forced to marry Maria Josepha of Saxony, Dauphine of France, against his will shortly after the death of his beloved first spouse, Maria Teresa Rafaela, in childbirth. This caused Louis to initially be hostile toward Maria Josepha, even more so when his only child with the Spanish Infanta died at the age of two, but she eventually managed to win his affection, upon the advice of Henriette.", "section_level": 2}, {"title": "Death.", "content": "Henriette died of smallpox in 1752 at the age of twenty-four. In February of that year, she had felt somewhat unwell and tired, but when the king asked her to accompany him on a sledge ride, she gave no signs of her discomfort, and accepted the invitation anyway. She was badly affected by the chilly weather, and died after just three days of illness. Her family was described as being in a \"state of stupefaction over the rapidity of the illness.\" Louis XV reacted with \"violent\" despair upon her death and gave order of the highest honors around her funeral; in order to enhance the public mourning, her remains were placed at the Tuileries instead of Versailles prior to the funeral, dressed in one of her finest dresses and made up so to appear alive. The public funeral reception was however not to the king's taste, as the public \"drank, laughed and amused themselves\", which was taken as a sign of the diminishing reputation of the monarchy. At the time, the public interpreted the death of Henriette as a sign of divine disapproval of the king's lifestyle. Her heart was interred in the Abbey of Val-de-Grace, while her remains were buried at the Basilica of Saint Denis, along with her sister Elisabeth. Her tomb, like other royal tombs at Saint-Denis, was destroyed during the French Revolution. Madame Campan later wrote about her: \"Madame Henriette, twin sister of the Duchess of Parma, was much regretted, for she had considerable influence over the King’s mind, and it was remarked that if she had lived she would have been assiduous in finding him amusements in the bosom of his family, would have followed him in his short excursions, and would have done the honours of the 'petits soupers' which he was so fond of giving in his private apartments.\"", "section_level": 2}], "src_summary": "Anne \"Henriette\" of France(14 August 1727 – 10 February 1752) was a French princess, the twin of Louise Élisabeth of France, and the second child of King Louis XV of France and queen consort Marie Leszczyńska.", "tgt_summary": null, "id": 4975128} {"src_title": "Irène Némirovsky", "tgt_title": null, "src_document": [{"title": "Life and career.", "content": "Némirovsky was born Irina Lvivna Nemirovska () in 1903 in Kiev, then Russian Empire, the daughter of a wealthy banker, Léon (Lev) Némirovsky. Her volatile and unhappy relationship with her mother became the heart of many of her novels. Her family fled the Russian Empire at the start of the Russian Revolution in 1917, spending a year in Finland in 1918 and then settling in Paris, where Némirovsky attended the Sorbonne and began writing when she was 18 years old. In 1926, Némirovsky married Michel Epstein, a banker, and had two daughters: Denise, born in 1929; and Élisabeth, in 1937. In 1929, she published \"David Golder\", the story of a Jewish banker unable to please his troubled daughter, which was an immediate success, and was adapted to the big screen by Julien Duvivier in 1930, with Harry Baur as David Golder. In 1930 her novel \"Le Bal\", the story of a mistreated daughter and the revenge of a teenager, became a play and a movie. The \"David Golder\" manuscript was sent by post to the \"Grasset\" publisher with a poste restante address and signed \"Epstein\". H. Muller, a reader for \"Grasset\" immediately tried to find the author but couldn't get hold of him/her. \"Grasset\" put an ad in the newspapers hoping to find the author, but the author was busy: she was having her first child, Denise. When Némirovsky finally showed up as the author of \"David Golder\", the unverified story is that the publisher was surprised that such a young woman was able to write such a powerful book. Although she was widely recognized as a major author – even by some anti-Semitic writers like Robert Brasillach – French citizenship was denied to the Némirovskys in 1938. Némirovsky was of Russian-Jewish origin, but was baptized into the Roman Catholic Church in 1939 and wrote in \"Candide\" and \"Gringoire\", two magazines with ultra-nationalist tendencies. After the war started, \"Gringoire\" was the only magazine that continued to publish her work, thus \"guarantee[ing] Némirovsky's family some desperately needed income\". By 1940, Némirovsky's husband was unable to continue working at the bank, and Némirovsky's books could no longer be published, because of her Jewish ancestry. Upon the Nazis' approach to Paris, they fled with their two daughters to the village of Issy-l'Evêque (the Némirovskys initially sent them to live with their nanny's family in Burgundy, while staying on in Paris themselves; they had already lost their Russian home and refused to lose their home in France), where Némirovsky was required to wear the Yellow star. On 13 July 1942, Némirovsky (then 39) was arrested as a \"stateless person of Jewish descent\" by policemen employed by Vichy France. As she was being taken away, she told her daughters, \"I am going on a journey now.\" She was brought to a convoy assembly camp at Pithiviers, and on 17 July 1942, together with 928 other Jewish deportees, transported to German concentration camp Auschwitz. Upon her arrival there two days later, her forearm was marked with an identification number. She died a month later of typhus.

These works are considered remarkable because they were written during the actual period itself, and yet are the product of considered reflection, rather than just a journal of events, as might be expected considering the personal turmoil experienced by the author at the time. Némirovsky's older daughter, Denise, kept the notebook containing the manuscript for \"Suite Française\" for fifty years without reading it, thinking it was a journal or diary of her mother's, which would be too painful to read. In the late 1990s, however, she made arrangements to donate her mother's papers to a French archive and decided to examine the notebook first. Upon discovering what it contained, she instead had it published in France, where it became a bestseller in 2004. It has since been translated into 38 languages and as of 2008 has sold 2.5 million copies. The original manuscript has been given to the \"Institut mémoires de l'édition contemporaine\" (IMEC), and the novel has won the Prix Renaudot – the first time the prize has been awarded posthumously. Némirovsky's surviving notes sketch a general outline of a story arc that was intended to include the two existing novellas, as well as three more to take place later during the war and at its end. She wrote that the rest of the work was \"in limbo, and what limbo! It's really in the lap of the gods since it depends on what happens.\" In a January 2006 interview with the BBC, her daughter, Denise, said, \"For me, the greatest joy is knowing that the book is being read.

Well, here is a Jewish writer who owed her success in France \"entre deux guerres\" in no small measure to her ability to pander to the forces of reaction, to the fascist right. Némirovsky's stories of corrupt Jews – some of them even have hooked noses, no less! – appeared in right-wing periodicals and won her the friendship of her editors, many of whom held positions of power in extreme-right political circles. When the racial laws in 1940 and 1941 cut off her ability to publish, she turned to those connections to seek special favors for herself, and even went so far as to write a personal plea to Marshal Pétain. Myriam Anissimov's introduction to the French edition of \"Suite Française\" describes Némirovsky as a \"self-hating Jew,\" due to the fact that Némirovsky's own situation as a Jew in France is not at all seen in the work.

In 1946 Major Sokolov (agent \"Davey\") was deported from Canada in relation to spying activity. After returning to the Soviet Union in 1946 and growing up there, Sokolov did not fit into the Soviet system. In 1965 he was discarded from a military university, probably because he had tried to flee the country. After that he studied journalism at Moscow State University from 1966 to 1971. Shortly after his first daughter was born in 1974 his first marriage ended. Sokolov made several attempts to flee from Soviet Union. He was caught while crossing the Iranian border, and only his father's connections helped him to avoid long imprisonment. He met his second wife, the Austrian-born Johanna Steindl while she was teaching German at the University in Moscow. She smuggled the text of his first novel into the West. Only after she started a hunger strike in the Stephansdom in Vienna, Austria, in 1975, was Sokolov allowed to leave the Soviet Union. Sokolov left Vienna in late 1976 for the United States after his first novel had been published. In early 1977, Johanna Steindl gave birth to Sokolov's son, who has become a journalist.

When Delicious was first launched, it was the first use of the term \"tag\" in the modern sense, and it was the first explicit opportunity where website users were given the ability to add their own tags to their bookmarks so that they could more easily search for them at a later time. This major breakthrough was not much noticed as most thought the application at the time \"cool\" but obvious. Yahoo acquired Delicious on December 9, 2005. Various guesses suggest it was sold for somewhere between US$15 million and US$30 million. In 2018, Schachter said the actual number was \"definitely less\" than US$30 million. On December 16, 2010, an internal slide from a Yahoo meeting leaked, indicating that Delicious would be \"sunsetted\" in the future, which seemed to mean \"shut down\". Later Yahoo clarified that they would be selling Delicious, not ending it. This news resulted in Delicious users looking for alternative sites.

Specifically, Keynesian economists argue that fiscal stimulus in the form of deficit spending is the most powerful method of fighting unemployment during a liquidity trap. Such stimulus may not be possible if states in a monetary union are not allowed to run sufficient deficits. The Post-Keynesian theory of Neo-Chartalism holds that government deficit spending creates money, that ability to print money is fundamental to a state's ability to command resources, and that \"money and monetary policy are intricately linked to political sovereignty and fiscal authority\".

However, another school of thought argues that some of the OCA criteria are not given and fixed, but rather they are economic outcomes (i.e., endogenous) determined by the creation of the currency union itself. Consider goods market interaction as an example: if the OCA criteria were applied before the currency union forms, then many countries might exhibit low trade volumes and low market integration; which means that OCA criteria are not met. Thus, the currency union might not be formed based on those current characteristics. However, if the currency union was established anyway, its member-states would trade so much more that, in the end, the OCA criteria would be met. This logic suggests that the OCA criteria can be self-fulfilling. Furthermore, greater integration under the OCA project might also improve other OCA criteria. For example, if goods markets are better connected, shocks will be more rapidly transmitted within the OCA and will be felt more symmetrically. However, caution should be employed when analysing the self-fulfilling argument. Firstly, the self-fulfilling effect's impact may not be significant. According to a recent study by Richard Baldwin, a trade economist at the Graduate Institute of International Studies in Geneva, the boost to trade within the Eurozone from the single currency is much smaller: between 5% and 15%, with a best estimate of 9%. The second counter-argument is that further goods market integration might also lead to more specialization in production. Once individual firms can easily serve the whole OCA market, and not just their national market, they will exploit economies of scale and concentrate production. Some sectors in the OCA might end up becoming concentrated in a few locations. The United States is a good example: financial services are centered in New York City, entertainment in Los Angeles, and technology in Silicon Valley. If specialization increases, each country will be less diversified and will face more asymmetric shocks; weakening the case for the self-fulfilling OCA argument.", "section_level": 2}], "src_summary": "In economics, an optimum currency area (OCA), also known as an optimal currency region (OCR), is a geographical region in which it would maximize economic efficiency to have the entire region share a single currency.

Dionysius, Bishop of Alexandria (247–265), relates the sufferings of his people in a letter addressed to Fabius, Bishop of Antioch, of which long extracts have been preserved in Eusebius' \"Historia Ecclesiae\". After describing how a Christian man and woman, Metras and Quinta, were seized and killed by the mob, and how the houses of several other Christians were pillaged, Dionysius continues: At that time Apollonia, \"parthénos presbytis\" (mostly likely meaning a deaconess) was held in high esteem. These men seized her also and by repeated blows broke all her teeth. They then erected outside the city gates a pile of wood and threatened to burn her alive if she refused to repeat after them impious words (either a blasphemy against Christ, or an invocation of the heathen gods). Given, at her own request, a little freedom, she sprang quickly into the fire and was burned to death. This brief tale was extended and moralized in Jacobus da Voragine's \"Golden Legend\" (c. 1260). Apollonia and a whole group of early martyrs did not await the death they were threatened with, but either to preserve their chastity or because they were confronted with the alternative of renouncing their faith or suffering death, voluntarily embraced the death prepared for them, an action that runs perilously close to suicide, some thought. Augustine of Hippo touches on this question in the first book of \"The City of God\", apropos suicide: But, they say, during the time of persecution certain holy women plunged into the water with the intention of being swept away by the waves and drowned, and thus preserve their threatened chastity. Although they quitted life in this wise, nevertheless they receive high honour as martyrs in the Catholic Church and their feasts are observed with great ceremony. This is a matter on which I dare not pass judgment lightly. For I know not but that the Church was divinely authorized through trustworthy revelations to honour thus the memory of these Christians. It may be that such is the case. May it not be, too, that these acted in such a manner, not through human caprice but on the command of God, not erroneously but through obedience, as we must believe in the case of Samson? When, however, God gives a command and makes it clearly known, who would account obedience there to a crime or condemn such pious devotion and ready service?\" The narrative of Dionysius does not suggest the slightest reproach as to this act of St. Apollonia; in his eyes she was as much a martyr as the others, and as such she was revered in the Alexandrian Church.

Air entering the building is filtered, as is common, but the air exhausted is cleaned as well. Bank of America Tower is the first skyscraper designed to attain a Platinum LEED Certification. The Bank of America Tower is constructed using a concrete manufactured with slag, a byproduct of blast furnaces. The mixture used in the tower concrete is 55% cement and 45% slag. The use of slag cement reduces damage to the environment by decreasing the amount of cement needed for the building, which in turn lowers the amount of carbon dioxide greenhouse gas produced through the normal cement manufacturing process. Each ton of regular cement produced creates about one ton of carbon dioxide in the atmosphere. Temperature control and the production of some of its energy are accomplished in an environmentally friendly manner for the tower. Insulated glazing reduces thermal loss, lowering energy consumption and increasing transparency. Carbon dioxide sensors signal increased fresh air ventilation when elevated levels of carbon dioxide are detected in the building.

It can also be a symptom of borderline personality disorder, which can be treated in the long term with proper psychotherapy and psychopharmacology. The treatment of chronic depersonalization is considered in depersonalization disorder. A recently completed study at Columbia University in New York City has shown positive effects from transcranial magnetic stimulation (TMS) to treat depersonalization disorder. Currently, however, the FDA has not approved TMS to treat DP. A 2001 Russian study showed that naloxone, a drug used to reverse the intoxicating effects of opioid drugs, can successfully treat depersonalization disorder. According to the study: \"In three of 14 patients, depersonalization symptoms disappeared entirely and seven patients showed a marked improvement. The therapeutic effect of naloxone provides evidence for the role of the endogenous opioid system in the pathogenesis of depersonalization.\" The anti convulsion drug Lamotrigine has shown some success in treating symptoms of depersonalization, often in combination with a Selective serotonin reuptake inhibitor and is the first drug of choice at the depersonalisation research unit at King's College London.", "section_level": 1}, {"title": "Research.", "content": "The Depersonalisation Research Unit at the Institute of Psychiatry in London conducts research into depersonalization disorder.

Trisha falls back to avoid listening and is therefore unable to find her family again after she wanders off the trail to take a bathroom break. Trying to catch up by attempting a shortcut, she slips and falls down a steep embankment and ends up hopelessly lost, heading deeper into the heart of the forest. She is left with a bottle of water, two Twinkies, a boiled egg, a tuna sandwich, a bottle of Surge, a poncho, a Game Boy, and a Walkman. She listens to her Walkman to keep her mood up, either to learn of news of the search for her, or to listen to the baseball game featuring her favorite player, and \"heartthrob,\" Tom Gordon. As she starts to take steps to survive by conserving what little food she has with her and consuming edible flora, Trisha's family return to their car without her and call the police to start a search. The rescuers search in the area around the path, but not as far as Trisha has gone. The girl decides to follow a creek because of what she read in \"Little House on the Prairie\" (though it soon turns into a swamp-like river), rationalizing that all bodies of water lead eventually to civilization. As the cops stop searching for the night, she huddles up underneath a tree to rest. Eventually, a combination of fear, hunger, and thirst causes Trisha to hallucinate. She imagines several people from her life, as well as her hero, Tom Gordon, appearing to her. It's left unclear whether increasingly obvious signs of supernatural events in the woods are also hallucinations. Hours and soon days begin to pass, with Trisha wandering further into the woods. Eventually she begins to believe that she is headed for a confrontation with the God of the Lost, a wasp-faced, evil entity who is hunting her down. Her trial becomes a test of a 9-year-old girl's ability to maintain sanity in the face of seemingly certain death. Racked with pneumonia and near death, she comes upon a road, but just as she discovers signs of civilization, she is confronted by a bear, which she interprets as the God of the Lost in disguise. Facing down her fear, she realizes it is the bottom of the ninth, and she must close the game. In imitation of Tom Gordon, she takes a pitcher's stance and throws her Walkman like a baseball, hitting the bear in the face, and startling it enough to make it back away.

Émile de La Bédollière wrote that the water came from la Villette and that the fountain was \"superb\" in character. In 1867, Gabriel Davioud built a more impressive fountain in the square, which (like the first fountain) was decorated with lions. The square took its current shape as part of Baron Hausmann's vast renovation of Paris. Haussmann also built new barracks on the cities, to garrison troops useful in times of civil unrest. At the center of the Place de la République is a bronze statue of Marianne, the personification of the French Republic, \"holding aloft an olive branch in her right hand and resting her left on a tablet engraved with Droits de l'homme (the Declaration of the Rights of Man and of the Citizen).\" The statue sits atop a monument which is high. Marianne is surrounded with three statues personifying liberty, equality, and fraternity, the values of the French Republic. These statues also evoke the three medieval theological virtues. Also at the base is a lion guarding a depiction of a ballot box. The monument has been described as \"an ordinary one, acceptable to a committee in the 1880s and inoffensively unarresting today.\" The monument was created by the brothers Charles and Léopold Morice. Leopold executed the sculptural segments, while Charles executed the architectural segments. The monument was chosen as part of an art competition announced in early 1879 by the Paris City Council, which sought to create a \"Monument to the French Republic\" in honor of the 90th anniversary of the French Revolution, to be erected on the Place de la République. The Morice statue was chosen by the jury, but a \"vociferous minority opinion among jury members claimed precedence for the second prize\", the submission of Jules Dalou, who had just returned from exile in England. Dalou's statue, which was completely different in style, impressed the jury so much that it was decided in early 1880 to erect his monument to the Republic on the adjacent Place de la Nation. Two inauguration ceremonies for the Morice monument took place, the first on 14 July 1880 with a gypsum model, and the second on 14 July 1883 with the final version in bronze. The monument replaced the second fountain. Paris mayor Bertrand Delanoë made a renovation of the Place de la République one of his campaign promises in the 2008 campaign for re-election. The project involved the transformation of the square from a \"glorified roundabout\" into a pedestrian zone, with 70% of the square's 3.4 hectares and surroundings roads being reserved for pedestrians. The Paris City Council allocated twelve million euros for renovating the square in 2010, and the project began the same year. The project was completed in 2013. The total cost of the project was 20.4 GBP, about 5 million GBP over budget. The renovation was a finalist for the European Prize for Urban Public Space. The pedestrian area now occupies \"some two hectares in the sunniest part on the north-eastern side\" while the \"other third, to be used by vehicular traffic, is the shadier part on the south-western side.\" The statue of Marianne was cleaned of graffiti and footprints as part of the renovations. After terrorist attacks against France in January 2015, crowds gathered in the square to mourn and express solidarity against the threat of Islamic extremism.

Strauss's parents, Franz Borgias Strauss (October 10, 1764 – April 5, 1816) and Barbara Dollmann (December 3, 1770 – August 28, 1811), were innkeepers (). He was born a Roman Catholic. His mother died of 'creeping fever' when he was seven and five years later his father drowned, possibly as a result of suicide, in the Danube river. Strauss' guardian, the tailor Anton Müller, placed him as an apprentice to the bookbinder, Johann Lichtscheidl; Strauss took lessons in the violin and viola in addition to fulfilling his apprenticeship. Contrary to a story later told by his son Johann II, Strauss successfully completed his bookbinder apprenticeship in 1822. He also studied music with Johann Polischansky during his apprenticeship and eventually managed to secure a place in a local orchestra, headed by Michael Pamer. Strauss left the orchestra to join a popular string quartet known as the \"Lanner Quartet\", formed by his would-be rivals Joseph Lanner and the Drahanek brothers, Karl and Johann. This string quartet playing Viennese Waltzes and rustic German dances expanded into a small string orchestra in 1824. Strauss became deputy conductor of the orchestra to assist Lanner in commissions after it became so popular during the Fasching of 1824 and Strauss was soon placed in command of a second smaller orchestra which was formed as a result of the success of the parent orchestra. In 1825, he decided to form his own band and began to write music (chiefly, dance music) for it to play after he realized that he could also possibly emulate the success of Lanner in addition to putting an end to his financial struggles. By so doing, he would have made Lanner a serious rival although the rivalry did not entail hostile consequences as the musical competition was very productive for the development of the waltz as well as other dance music in Vienna. He soon became one of the best-known and well loved dance composers in Vienna. During the carnival of 1826, Strauss inaugurated his long line of triumphs by introducing his band to the public of Vienna at the in the suburb of Roßau where his Täuberln-Walzer (Op. 1) at once established his reputation. He toured with his band to Germany, the Netherlands, Belgium and Britain. The conducting reins and management of this Strauss Orchestra would eventually be passed on to the hands of his sons until its disbandment by Eduard Strauss in 1901. On a trip to France in 1837 he heard the quadrille and began to compose them himself, becoming largely responsible for introducing that dance to Austria in the 1840 Fasching, where it became very popular. It was this very trip (in 1837) which has proved Strauss' popularity with audiences from different social backgrounds and this paved the way to forming an ambitious plan to perform his music in England for the coronation of Queen Victoria in 1838. Strauss also adapted various popular melodies of his day into his works so as to ensure a wider audience, as evidenced in the incorporation of the \"Oberon\" overture into his early waltz, \"Wiener Carneval\", Op. 3, and also the French national anthem \"La Marseillaise\" into his \"Paris-Walzer\", Op. 101. Strauss married Maria Anna Streim in 1825 in the Roman Catholic Lichtental Parish Church in Vienna. The marriage was relatively unhappy due to his prolonged absences caused by frequent tours abroad which led to a gradual alienation. They had seven children; Johann, Josef and Eduard Strauss, the last of whom had a son called Johann Strauss III. Strauss Sr. also had two daughters, Anna, who was born in 1829, and Therese, who was born in 1831. His third son, Ferdinand, born in 1834, lived only ten months. The family home was called 'Hirschenhaus' but was better known in Vienna as the 'Goldener Hirsch' (The Golden Stag). Strauss was a strict disciplinarian and demanded that none of his sons pursue careers in music, despite their display of musical talent. Johann Junior was to study banking, likewise his brother Josef Strauss was destined for a military career, whereas the youngest Eduard Strauss was expected to join the Austrian consulate. By 1834 Strauss had taken a mistress, Emilie Trampusch, with whom he had eight children. When her husband openly acknowledged his paternity of a daughter born to Emilie in 1844, Maria Anna sued for divorce. With the ending of the marriage Anna Strauss determined to further Johann Strauss II's musical career, allowing him to develop his skills as a composer. Despite family problems, Strauss senior continued to tour frequently and was always prepared to write novelty pieces for numerous charitable organizations. His waltzes were gradually developed from a rustic peasant dance into one which posterity would recognize as the Viennese Waltz. They were written in three-quarter time with a short introduction; often with little or no reference to the later chain of five two-part waltz structure; usually appended with a short coda and concluded in a stirring finish, although his son Johann Strauss II expanded the waltz structure and utilized more instruments than his father. While he did not possess a musical talent as rich as his eldest son's, nor a business mind as astute, he was among the handful of early waltz composers along with Joseph Lanner to actively write pieces with individual titles — with the view to boost sales of their sheet music — which enabled music enthusiasts to easily recognize those pieces. In fact, during his performances at the Sperl-Ballroom in Vienna, where he established his name, he actively pursued the concept of collecting a fixed entrance fee from the patrons of the ballroom instead of the old practice of passing around a collection plate where income was reliant on the goodwill of the patrons. Johann Strauss II often played his father's works and openly declared his admiration of them, although it was no secret to the Viennese that their rivalry was intense, with the press at that time fueling it. Johann Strauss I himself refused to play ever again at the Dommayer's Casino, which offered his son his conducting debut, and was to tower over his son during his lifetime in terms of career advancement, although Strauss II was to eclipse him in terms of popularity in the classical repertoire. In 1846, Johann Strauss I was awarded the honorary title of \"K.K. Hofballmusikdirektor\" (Director of Music for the Imperial and Royal Court Balls) by Emperor Ferdinand I. Strauss died in Vienna on September 25, 1849 at the age of 45 from scarlet fever contracted from one of his illegitimate children. He was buried at the Döblinger cemetery beside his friend Joseph Lanner. In 1904, both of their remains were transferred to the graves of honour at the Zentralfriedhof. The former Döbling Cemetery is now a Strauss-Lanner Park. Hector Berlioz himself paid tribute to the 'Father of the Viennese Waltz' by commenting that \"Vienna without Strauss is like Austria without the Danube\".

It is there that young Victor attended elementary school. When his family returned to Romania in 1914, he continued his studies at the Lutheran school in Brăila. His interests revolved around zoology during that period. He attended the National School of Fine Arts in Bucharest (1916–1918) and Horia Igiroşanu private school of painting. He visited Fălticeni and Balcic, and started painting landscapes in the manner of Paul Cézanne. Then, as he testified himself, he went through all the stages: \"Dadaist, Abstractionist, Expressionist\". On 26 September 1924, the Mozart Galleries in Bucharest hosted his first personal exhibition. In that period he met poet Ilarie Voronca, together with whom he founded the \"75HP\" magazine. It was in this magazine that Brauner published the manifesto \"The Pictopoetry\" and the article \"The Surrationalism\". He painted and exhibited \"Christ at the Cabaret\" (in the manner of George Grosz) and \"The Girl in the Factory\" (in the manner of Hodler). He participated to the \"Contimporanul\" exhibition in November 1924. In 1925, he undertook his first journey to Paris, from where he returned in 1927. In the period 1928–1931 he was a contributor of the \"unu\" magazine (an avant-garde periodical with Dadaist and Surrealist tendencies), which published reproductions of most of his paintings and graphic works: \"clear drawings and portraits made by Victor Brauner to his friends, poets and writers\" (Jaques Lessaigne – \"Painters I Knew\"). In 1930, he settled in Paris, where he met Constantin Brâncuși, who instructed him in methods of art photography. In that same period he became a friend of the Romanian poet Benjamin Fondane and met Yves Tanguy, who would later introduce him to the circle of the Surrealists. He lived on Moulin Vert Street, in the same building as Alberto Giacometti and Tanguy. He painted \"Self-portrait with enucleated eye\", a premonitory theme. In 1934 André Breton wrote an introduction to the catalogue for Brauner’s first Parisian solo exhibition at the Pierre Gallery. The theme of the eye was omnipresent: \"Mr. K's power of concentration\" and \"The strange case of Mr. K\" are paintings that Breton compared with Alfred Jarry’s play \"Ubu Roi\", \"a huge, caricature-like satire of the bourgeoisie\". In 1935, Brauner returned to Bucharest. He joined the ranks of the Romanian Communist Party for a short while, without a very firm conviction. On 7 April 1935, he opened a new personal exhibition at the Mozart Galleries. Saşa Pană wrote about it in his autobiographical novel \"Born in 02\": The catalogue shows 16 paintings; they are accompanied by verse, surrealist images that are exquisite by their bizarreness – they are perhaps the creations of automatic dictation and they certainly bear no connection to the painting itself. They are written in French, but their colorful taste is kept in their Romanian language translation. The exhibition brought about many interesting articles and takings of position regarding Surrealism in arts and literature. Another remark about Brauner’s participation to Surrealist exhibitions: \"Despite its appearance of abstract formula... this trend is a point of transition to the art that is to come\" (Dolfi Trost, in \"Rampa\" of 14 April 1935). In \"Cuvântul liber\" of 20 April 1935, Miron Radu Paraschivescu wrote in the article \"Victor Brauner’s exhibition\": \"In contrast to what one may see, for instance, in the neighboring exhibition halls, Victor Brauner’s painting means integration, an attitude that is a social one, as far as art allows it. For V. Brauner takes attitude through the very character and ideology of his art\".

On 28 August, he lost his left eye in a violent argument between Oscar Domínguez and Esteban Francés. Brauner attempted to protect Esteban and was hit by a glass thrown by Domínguez: the premonition became true. That same year, he met Jaqueline Abraham, who was to become his wife. He created a series of paintings called \"lycanthropic\" or sometimes \"chimeras\". He left Paris during Nazi Germany's invasion of France in 1940, together with Pierre Mabille. He lived for a while in Perpignan, at Robert Rius', then at Cant-Blage, in the Eastern Pyrenees and at Saint Feliu d'Amont, where he was forcibly secluded. However, he kept in touch with the Surrealists who had taken refuge in Marseille. In 1941, he was granted the permission to settle in Marseille. Seriously ill, he was hospitalized at the \"Paradis\" clinic. He painted \"Prelude to a civilization\" in 1954, now in New York's Metropolitan Museum of Art. The painting is in encaustic on Masonite. After the war, he took part in the Venice Biennale, and traveled to Italy. In 1959, he settled in a studio at 72, rue Lepic, in Montmartre. In 1961, he traveled to Italy again. In the same year, New York City's Bodley Gallery mounted a solo exhibition of Brauner's work. He settled in Varengeville in Normandy, where he spent most of his time working. In 1965, he created an ensemble of object-paintings, grouped under the titles \"Mythologie\" and \"Fêtes des mères\". These paintings were made in Varengeville and in Athanor in 1964, where Brauner retreated. His last painting, \"La fin et le debut\" (made in 1965), reminds us that \"when the painter's life ends, his work starts living\". In 1966, he was chosen to represent France at the Venice Biennale, where an entire hall was dedicated to him. He died in Paris as a result of a prolonged illness. The epitaph on his tomb from the Montmartre cemetery is a phrase from his notebooks: \"Peindre, c'est la vie, la vraie vie, ma vie\" (\"Painting is life, the real life, my life\"). The painter’s notebooks with private notes, which he handed to Max Pol Fouchet, partly enclose the \"key\" of his creation: \"Each painting that I make is projected from the deepest sources of my anxiety...\" Victor Brauner's brother, Harry Brauner, was a folklorist who later married Lena Constante.", "section_level": 1}], "src_summary": "Victor Brauner (, also spelled Viktor Brauner; 15 June 1903 – 12 March 1966) was a Romanian sculptor and painter of surrealistic images.", "tgt_summary": null, "id": 4975146} {"src_title": "Dorothea von Medem", "tgt_title": null, "src_document": [{"title": "Biography.", "content": "Anna Charlotte Dorothea was born at Mežotne, now Latvia, to Johann Friedrich von Medem, a Graf from the old Courland nobility, general-poruchik of the Russian Empire, and (as of 1779) Reichsgraf of the Holy Roman Empire; and his second wife, Louise Charlotte von Manteuffel.

The distillery was rebuilt 1880–87 and extended in 1900. When a new lease for the distillery was negotiated with the chief of Clan MacLeod in 1892 the annual payment was to be £23.12s and a ten-gallon cask of best-quality Talisker. It was rebuilt in 1960 after a stillhouse fire completely destroyed the distillery. The distillery operates five stills; two wash stills and three spirit stills. All the stills use worm tubs (condensing coils) rather than a modern condenser, which are believed to give the whisky a \"fuller\" flavour (itself an indication of higher sugar content). During this early period, the whisky was produced using a triple distilling method, but changed to the more conventional double distilling in 1928. Talisker was acquired by Distillers Company in 1925 and is now part of Diageo. After the 1960 fire, five exact replicas of the original stills were constructed to preserve the original Talisker flavour. In 1972 the stills were converted to steam heating and the maltings floor was demolished. Talisker's water comes from springs directly above the distillery via a network of pipes and wells. The malted barley used in production comes from Muir of Ord. Talisker has an unusual feature—swan neck lye pipes. A loop in the pipes takes the vapour from the stills to the worm tubs so some of the alcohol already condenses before it reaches the cooler. It then runs back into the stills and is distilled again. Talisker now has an annual output of three and a half million litres of spirit. Talisker was the favourite whisky of writers Robert Louis Stevenson and HV Morton. In his poem \"The Scotsman's Return From Abroad\", Stevenson mentioned \"The king o' drinks, as I conceive it, Talisker, Islay, or Glenlivet.\" Recently, Talisker has come under scrutiny after a radiocarbon study suggested Talisker 1863 whisky was produced much later, either between 1957-58 or 2007-2014.", "section_level": 1}, {"title": "Character.", "content": "The spirit is most frequently matured in American oak casks.

Their motto was the tongue-in-cheek Latin phrase \"Non Gratus Anus Rodentum\" (\"not worth a rat's arse\"). In the early stages of the war against the French colonial forces, the Viet Minh created an extensive underground system of tunnels, which was later expanded and improved by the Viet Cong. By the 1960s, the tunnel complexes included hospitals, training areas, storage facilities, headquarters, and barracks. These diverse facilities, coupled with sophisticated ventilation systems, allowed VC guerrillas to remain hidden underground for months at a time. During the Vietnam War, U.S. and ANZAC troops uncovered a great number of enemy tunnels while patrolling or conducting larger operations. The men of the 3 Field Force, an Australian combat engineering unit that served in Vietnam from 1965-1966, have made a convincing argument that they were the first allied troops to enter the tunnels. Tunnel rats were given the task of destroying them, gathering intelligence within them, and killing or capturing their occupants—often in conditions of close combat. Typically, a tunnel rat was equipped with only a standard issue M1911 pistol or M1917 revolver, a bayonet, a flashlight, and explosives. Many tunnel rats reportedly came to dislike the intense muzzle blast of the relatively large.45 caliber round, as the.45's loud report could often leave one temporarily deaf when fired in a confined space. Consequently, some preferred to clear tunnels armed with a.38 Special revolver equipped with a sound suppressor and other non-standard weapons. \"A few of the OSS-ordered World War II era suppressed High Standard HD.22 automatics made their way into Tunnel Rat hands. But these weapons were very few in number and wanted by a number of other special units. Personal weapons were used by the rats, ranging from.25 caliber automatics to sawn-off shotguns.\" Besides enemy combatants, the tunnels themselves presented many potential dangers to tunnel rats. Sometimes they were poorly constructed and they would simply collapse. Tunnels were often booby trapped with hand grenades, anti-personnel mines, and punji sticks. The VC would even use venomous snakes (placed as living booby traps). Rats, spiders, scorpions, and ants also posed threats to tunnel rats. Bats also roosted in the tunnels, although they were generally more of a nuisance than a threat. Tunnel construction occasionally included anti-intruder features such as U-bends that could be flooded quickly to trap and drown the tunnel rat. Sometimes poison gases were used. A tunnel rat might therefore choose to enter the tunnels wearing a gas mask (donning one within was frequently impossible in such a confined space). According to U.S. tunnel rat veterans, however, most tunnel rats usually went without gas masks because wearing one made it even harder to see, hear, and breathe in the narrow dark passages. Tunnel rats were generally men of smaller stature ( and under), who were able to maneuver more comfortably in the narrow tunnels. Tom Mangold and John Penycate, authors of one of the definitive accounts of tunnel warfare in the Vietnam War, reported that U.S. tunnel rats were almost exclusively white or Hispanic soldiers, many of whom were Puerto Rican or Mexican American. By Mangold and Penycate's account, the contributions of tunnel rats first garnered public attention in January 1966, after a combined U.S. and Australian operation against the Củ Chi tunnels in Bình Dương Province, known as Operation Crimp. The \"Diehards\" of the U.S. Army's 1st Engineer Battalion, whose exploits are featured in Mangold and Penycate's book, later claimed a special place for tunnel rats in American military history during their rotation through the Cu Chi District of Vietnam in 1969.

His interpretation, based solely on the early writers, greatly influenced Vatican II's treatment of Mary in chapter VIII of the Constitution on the Church, \"Lumen gentium\", and Pope Paul VI, quoting Ambrose, declared Mary the \"Mother of the Church,\" a title actively promoted by Popes John Paul II and Benedict XVI. The latter specifically gives credit to Rahner in this regard. At first sight, J. Ratzinger argues, it may seem accidental that the Council moved mariology into ecclesiology. But this relation helps to understand what \"\"Church\"\" really is, as Ratzinger maintains: Hugo Rahner showed that Mariology was originally ecclesiology; the Church is like Mary. The Church is virgin and mother, she is immaculate and carries the burdens of history. She suffers and she is assumed into heaven. Slowly the Church learns that Mary is her mirror, that she is a person in Mary. Mary, on the other hand, is not an isolated individual, who rests in herself. She carries the mystery of the Church. Pope Benedict lamented that this unity of the Church and Mary, brought to light by Rahner, was overshadowed in later centuries which overburdened Mary with privileges and removed her to a far distance. Both mariology and ecclesiology suffered from this. A Marian view of the Church and an ecclesiological view of Mary in salvation history lead directly to Christ. It brings to light what is meant by holiness and by \"God being human\". Only one work on mariology, \"Our Lady and the Church\", is translated into English. The book received great praise not only from Pope Benedict XVI but also from the American Jesuit theologian Cardinal Avery Dulles, who said of it: \"With engaging clarity, this pioneering study sets forth the vast range of biblical metaphors the Fathers applied to Mary and the Church: ark of the covenant, valiant woman, treasure-laden ship.

In contrast, while Rahner does acknowledge that the Church of late antiquity adopted many of its nonessential markers and ritualistic dressings from with pagan mysticism, all essential elements of the Christian mystery and the emergent Church remained untarnished by external influence and independent from conception. According to this view, the presence of Roman cults which dominated the environment in which the early Church gained its footing and eventually gained supremacy was not necessary for the Church's foundation but merely helped shape features and rites of the institution without invading or influencing Christianity's core tenets. For example, Rahner's analysis notes the centrality of celestial bodies including the Sun (Helios) and Moon (Luna)- both longstanding entities of cultic devotion- in Roman paganism and the early Church's intentional, analogous use of the Sun and Moon as symbols of Jesus Christ and Mary (or, alternatively, the Church), respectively.", "section_level": 2}], "src_summary": "Hugo Karl Erich Rahner, S.J.

Edward demanded that they walk out wearing nooses around their necks, and carrying the keys to the city and castle. One of the wealthiest of the town leaders, Eustache de Saint Pierre, volunteered first, and five other burghers joined with him. Saint Pierre led this envoy of volunteers to the city gates. It was this moment, and this poignant mix of defeat, heroic self-sacrifice, and willingness to face imminent death that Rodin captured in his sculpture, scaled somewhat larger than life. According to Froissart's story, the burghers expected to be executed, but their lives were spared by the intervention of England's queen, Philippa of Hainault, who persuaded her husband to exercise mercy by claiming that their deaths would be a bad omen for her unborn child.

Two prior artists were prevented from creating the sculpture: David d'Angers by his death, and Auguste Clésinger by the Franco-Prussian War. In 1884 the municipal corporation of the city invited several artists, Rodin amongst them, to submit proposals for the project. Rodin's design, which included all six figures rather than just de Saint Pierre, was controversial. The public felt that it lacked \"overtly heroic antique references\" which were considered integral to public sculpture. It was not a pyramidal arrangement and contained no allegorical figures. It was intended to be placed at ground level, rather than on a pedestal. The burghers were not presented in a positive image of glory; instead, they display \"pain, anguish and fatalism\". To Rodin, this was nevertheless heroic, the heroism of self-sacrifice. In 1895 the monument was installed in Calais on a large pedestal in front of Parc Richelieu, a public park, contrary to the sculptor's wishes, who wanted contemporary townsfolk to \"almost bump into\" the figures and feel solidarity with them.

After earning his doctorate, he worked for Edmund Hartnack's optical workshop in Potsdam designing microscope objectives. In 1891, after the death of Hartnack, he moved to Rathenow and took a job with the optical company Schulze & Barthels, where he developed telescopes, binoculars, and one of the first tele lenses for cameras. In 1894 he went to Voigtländer & Sohn in Braunschweig, where he held the post of technical director and also worked on improving rifle scopes. In 1899 he succeeded Hermann Wilhelm Vogel at the Royal Technical University in Berlin as professor of photography, photochemistry, and spectral analysis. Miethe was the designer of a camera for color photography, the first photographic product made by the Berlin cabinetmaker Wilhelm Bermpohl. Introduced to the public in 1903, it produced sets of three separate black-and-white images on glass plates by making a series of three photographs of the subject through red, green and blue color fliters, a method of color photography first proposed by James Clerk Maxwell. These were used to reconstitute the full original range of color by projecting transparent positives made from them through similar filters and exactly superimposing the images on the projection screen (additive color), or by making three prints consisting of transparent pigment or dye images in the complementary colors and superimposing those to make a single full-color transparency or print on paper (subtractive color). They were also used to prepare printing plates for illustrating books, periodicals and other mechanically printed media, the only form in which early color photographs were likely to be seen by the general public. There were a number of technical issues with the system, including the relatively long time required to make each sequence of three exposures and the difficulty of correctly balancing them to obtain accurate color values under different lighting conditions. In 1901, Miethe had introduced \"Ethyl Red\", a sensitizing dye that greatly improved the characteristics of panchromatically sensitized photographic emulsions, which in turn obviated the very long exposures previously needed to photograph red-filtered images, simplified color filter design, and generally cleared the path for future progress. Miethe's innovations provided the technological foundation used by such photographic pioneers as the Russian Sergey Prokudin-Gorsky, who studied with Miethe for several weeks in 1902. In 1909, Miethe began working with an observatory for astrophotography. This interest led him to participate in several overseas expeditions, such as one in 1908 to Upper Egypt to examine twilight phenomena and the ultraviolet end of the solar spectrum. In 1910 he took part in a shipborne expedition to Spitsbergen led by Count Ferdinand von Zeppelin that focused primarily on meteorological issues but also considered the viability of exploring the polar regions by airship. In 1914, he led an expedition to Norway to observe the 21 August solar eclipse. In 1921, he set up a research institute for cinema technology for which he served as chairman of the board of trustees. Miethe wrote several books and close to a hundred articles on photography. He took over the editorship of \"Photographischen Wochenblattes\" (Photographic Week) in 1889, and in 1894 he founded the magazines \"Atelier des Photographen\" (Photographer's Studio) and \"Photographische Chronik\" (Photographic Chronicle).

Following Luisa Carlotta's suggestion, Ferdinand VII sent for Maria Christina, his niece, who had already given birth to a child and pleased the King's eyes. The two were wed on 12 December 1829 at the Church of the Atocha. With her betrothal and then marriage to Ferdinand VII, Maria Christina became embroiled in the conflict between the Spanish Liberals and the Carlists.

In other common models, elements are implemented as lightweight threads or as coroutines to reduce the OS overhead often involved with processes. Depending upon the OS, threads may be scheduled directly by the OS or by a thread manager. Coroutines are always scheduled by a coroutine manager of some form. Usually, read and write requests are blocking operations, which means that the execution of the source process, upon writing, is suspended until all data could be written to the destination process, and, likewise, the execution of the destination process, upon reading, is suspended until at least some of the requested data could be obtained from the source process. This cannot lead to a deadlock, where both processes would wait indefinitely for each other to respond, since at least one of the two processes will soon thereafter have its request serviced by the operating system, and continue to run. For performance, most operating systems implementing pipes use pipe buffers, which allow the source process to provide more data than the destination process is currently able or willing to receive. Under most Unices and Unix-like operating systems, a special command is also available which implements a pipe buffer of potentially much larger and configurable size, typically called \"buffer\". This command can be useful if the destination process is significantly slower than the source process, but it is anyway desired that the source process can complete its task as soon as possible. E.g., if the source process consists of a command which reads an audio track from a CD and the destination process consists of a command which compresses the waveform audio data to a format like MP3. In this case, buffering the entire track in a pipe buffer would allow the CD drive to spin down more quickly, and enable the user to remove the CD from the drive before the encoding process has finished.

Instead of spawning processes with external programs, CMS Pipelines features a lightweight dispatcher to concurrently execute instances of built-in programs to run the pipeline. More than 200 built-in programs that implement typical UNIX utilities and interface to devices and operating system services. In addition to the built-in programs, CMS Pipelines defines a framework to allow user-written REXX programs with input and output streams that can be used in the pipeline. Data on IBM mainframes typically resides in a Record-oriented filesystem and connected I/O devices operate in record mode rather than stream mode. As a consequence, data in CMS Pipelines is handled in record mode. For text files, a record holds one line of text. In general, CMS Pipelines does not buffer the data but passes records of data in a lock-step fashion from one program to the next. This ensures a deterministic flow of data through a network of interconnected pipelines.", "section_level": 1}, {"title": "Object pipelines.", "content": "Beside byte stream-based pipelines, there are also object pipelines.

Rather than providing a save dialog box containing a file manager to let the user specify where a program should write data, RISC OS and ROX provide a save dialog box containing an icon (and a field to specify the name). The destination is specified by dragging and dropping the icon. The user can drop the icon anywhere an already-saved file could be dropped, including onto icons of other programs. If the icon is dropped onto a program's icon, it's loaded and the contents that would otherwise have been saved are passed in on the new program's standard input stream. For instance, a user browsing the world-wide web might come across a.gz compressed image which they want to edit and re-upload. Using GUI pipelines, they could drag the link to their de-archiving program, drag the icon representing the extracted contents to their image editor, edit it, open the save as dialog, and drag its icon to their uploading software. Conceptually, this method could be used with a conventional save dialog box, but this would require the user's programs to have an obvious and easily accessible location in the filesystem that can be navigated to. In practice, this is often not the case, so GUI pipelines are rare.", "section_level": 1}, {"title": "Other considerations.", "content": "The name 'pipeline' comes from a rough analogy with physical plumbing in that a pipeline usually allows information to flow in only one direction, like water often flows in a pipe.

The concept of pipeline is also central to the Cocoon web development framework or to any XProc (the W3C Standards) implementations, where it allows a source stream to be modified before eventual display. This pattern encourages the use of text streams as the input and output of programs. This reliance on text has to be accounted when creating graphic shells to text programs.", "section_level": 1}], "src_summary": "In software engineering, a pipeline consists of a chain of processing elements (processes, threads, coroutines, functions, \"etc.\"), arranged so that the output of each element is the input of the next; the name is by analogy to a physical pipeline.

The information that flows in these pipelines is often a stream of records, bytes, or bits, and the elements of a pipeline may be called filters; this is also called the pipes and filters design pattern.

His ancestors were Sephardi Jews. His paternal ancestors settled in Ruse from Ottoman Adrianople. The original family name was \"Cañete\", named after Cañete, Cuenca, a village in Spain. In Ruse, Canetti's father and grandfather were successful merchants who operated out of a commercial building, which they had built in 1898. Canetti's mother descended from the Arditti family, one of the oldest Sephardi families in Bulgaria, who were among the founders of the Ruse Jewish colony in the late 18th century. The Ardittis can be traced to the 14th century, when they were court physicians and astronomers to the Aragonese royal court of Alfonso IV and Pedro IV. Before settling in Ruse, they had migrated into Italy and lived in Livorno in the 17th century. Canetti spent his childhood years, from 1905 to 1911, in Ruse until the family moved to Manchester, England, where Canetti's father joined a business established by his wife's brothers. In 1912, his father died suddenly, and his mother moved with their children first to Lausanne, then Vienna in the same year. They lived in Vienna from the time Canetti was aged seven onwards. His mother insisted that he speak German, and taught it to him. By this time Canetti already spoke Ladino (his native language), Bulgarian, English, and some French; the latter two he studied in the one year they were in Britain. Subsequently, the family moved first (from 1916 to 1921) to Zürich and then (until 1924) to Frankfurt, where Canetti graduated from high school. Canetti went back to Vienna in 1924 in order to study chemistry. However, his primary interests during his years in Vienna became philosophy and literature. Introduced into the literary circles of First-Republic-Vienna, he started writing. Politically leaning towards the left, he was present at the July Revolt of 1927 – he came near to the action accidentally, was most impressed by the burning of books (recalled frequently in his writings), and left the place quickly with his bicycle. He gained a degree in chemistry from the University of Vienna in 1929, but never worked as a chemist. He published two works in Vienna before escaping to Great Britain. He reflected the experiences of Nazi Germany and political chaos in his works, especially exploring mob action and group thinking in his novel \"Die Blendung\" (\"Auto-da-Fé\", 1935) and non-fiction \"Crowds and Power\" (1960).

The people of North Carolina thought that he would best represent them because of his activism for the American cause of independence, which appealed to people in other states as well. However initially, Joseph Hewes was not in favor of independence but came to accept the idea due to the urging of his constituents in North Carolina. He was a representative in the last Province of North Carolina House of Burgesses in 1775. In later years John Adams wrote of the struggles that Hewes experienced as he set about serving in the Continental Congress: \"For many days the majority depended on Mr. Hewes of North Carolina. While a member one day was speaking and reading documents from all the colonies to prove that public opinion, the general sense of all, was in favor of the measure, when he came to North Carolina and produced letters and public proceedings that the majority in that colony was in favor of it, Mr. Hewes, who had hitherto constantly voted against it, started suddenly upright and lifting both hands to heaven as if he had been in a trance, cried out, \"It is done and I will abide by it.\" I would give more for the perfect painting of the terror and horror upon the face of the old majority at that critical moment than for the best piece of Raphael. The question, however, was eluded by an immediate motion for adjournment\". Though the people of the United States wanted independence, Hewes found it much harder in Congress to convey his opinion without being laughed at or scolded. Even in the year leading up to the revolution, more than two-thirds of the Continental Congress still believed that ties between King George and the colonies could stay intact. Hewes was barely able to speak in Congress because he was usually interrupted by those who disagreed with him. Nevertheless, he was actively involved in many committees, most of which favored the revolution. One such committee was the Committee of Correspondence, which advocated ideas that supported independence. One of the ideas that Hewes contributed to this committee was the following statement: \"State the rights of the colonies in general, the several instances in which these rights are violated or infringed, and the means most proper to be pursued for obtaining a restoration of them.\" Traditionally the Quakers were pacifists. Ironically, Hewes was not only one of the few people in favor of a war against Britain but was one of the few Quakers in Congress. The Quakers not only opposed war, but strongly opposed the committees that supported war too. Despite Joseph Hewes' obvious departure from Quaker principles, he did continue to have a relationship with his family and visited his mother, a Quaker minister, when he was able.

He was also involved with the secret committee of claims, which further promoted the independence of the colonies. Hewes was one of the primary reasons why North Carolina submitted to independence before any other colony. Hewes was initially faced with an ill-equipped navy of which to fight the British Navy.

Although this was confirmed in 1505 by Pope Julius II, the Order of Saint Lazarus resisted this move and the order of St. John never came into possession of this property except in Germany. In France, the Bull of suppression was ignored and French Grand Masters appointed. The order of Saint John claimed the possession of the French holdings but their claim was legally rejected in 1547 by the Parliament of Paris. In 1565 Pope Pius IV annulled the Bulls of his predecessors and restored all possessions to the order so that he might give the grand magistry to a favorite, Giovanni de Castiglione. But the latter did not succeed in securing the devolution of the commanderies in France.

This order was then linked in perpetuity with the Crown of Savoy and thenceforth the title of its Grand Master was hereditary in that house. By the time of Pope Clement VIII the order had two houses, one at Turin, was to contribute to combats on land, while the other, at Nice, had to provide galleys to fight the Turks at sea. But when thus reduced to the states of the Duke of Savoy, the order merely vegetated until the French Revolution, which suppressed it. In 1816 the King of Sardinia, Victor Emmanuel I, re-established the titles of Knight and Commander of Sts. Maurice and Lazarus, as simple decorations, accessible without conditions of birth to both civilians and military men. This became a national order of chivalry on the unification of Italy in 1861, but has been suppressed by law since the foundation of the Republic in 1946. Since 1951 the order has not been recognized officially by the Italian state. However, the House of Savoy in exile continued to bestow the order.

King Henry IV founded in 1608, with the approbation of Pope Paul V, the Order of Notre-Dame du Mont-Carmel. He then, in turn, united to this new order the possessions of St. Lazarus in France, and such is the origin of the title \"Ordres Royaux, Militaires & Hospitaliers de Saint Lazare de Jérusalem & de Notre-Dame du Mont-Carmel réunis\" (\"Royal, Military, and Hospitaller Orders of Our Lady of Mount Carmel and St. Lazarus of Jerusalem united\"). This amalgamation eventually received formal canonical acceptance on 5 June 1668 by a bull issued by Cardinal Legate de Vendôme under Papal authority of Clement IX. Unlike the situation with the Savoyian Order of Saints Maurice and Lazarus where a complete merger took place creating one order, the French branch was not completely merged with the Order of Our Lady of Mount Carmel, and the orders were managed as two separate entities, with individuals being admitted to one order but not necessarily to both. During the French Revolution, a decree of 30 July 1791 suppressed all royal and knightly orders in France. Another decree the following year confiscated all the Order's properties. The Holy See, which had originally created the Order, on the other hand did not suppress the order; while Louis, Count of Provence, then Grand Master of the order, who later became Louis XVIII, continued to function in exile and continued admitting various dignitaries to the order. Scholars differ in their views regarding the extent to which the Order remained active during and after the French Revolution. There is however no doubt of its continuing existence during this time. In different museums, there are preserved a number of paintings of Russian and Baltic nobles, admitted to the order after 1791. In this list are general John Lamb, Prince Suvorov, count Pahlen, count Sievers etc. Some of the new knights are listed in Almanach Royal from 1814 to 1830.

It was recognised by King Fulk of Jerusalem in 1142 and canonically recognised as a hospitaller and military order of chivalry under the rule of Saint Augustine in the Papal bull \"Cum a Nobis Petitur\" of Pope Alexander IV in 1255. Although they were centered on their charism of caring for those afflicted with leprosy, the knights of the Order of Saint Lazarus notably fought in the Battle of La Forbie in 1244 and in the Defense of Acre in 1291.

While the standard route up the peak is not severely difficult in modern technical terms, it presented quite a formidable undertaking in the earliest days, owing to the isolation of the peak, the heat of the desert and the total lack of water. Before the First World War what is now Namibia was German South-West Africa. It is possible that the main peak was reached as early as 1904, when a soldier of the Imperial Schutztruppe supposedly soloed the peak and made a fire on the summit. What he may have burned remains a mystery, as there is absolutely no natural fuel of any kind on the upper parts of the peak. The legend suggests that he never returned and that his body was never recovered. Certainly, no proof of his conquest is available today. The first documented conquest was made by a team of climbers from Cape Town, led by S. le Roux. The next party – O'Neil, Shipley and Schaff – pioneered a route up the northern extremes of the peak, after having failed on the southwest ridge. They gained access to the gully now known as the \"scramble\" but ran out of time to attempt the final faces. Four days later they made another attempt but finally gave up. Some of the earliest climbers, defeated by an extraordinarily smooth band of granite only about 3m high, resorted to carving steps into the rock with a hammer and chisel. A few months later Hans and Else Wong and Jannie de Villiers Graaff arrived and they reached the summit at noon, in November 1946. For the next quarter of a century the mountain maintained its reputation of presenting a two- or three-day struggle to potential climbers. (There are accounts of these ascents in old volumes of the \"Journal of The Mountain Club of South Africa\" – one of which can be found at scanned extracts from MCSA Journal). This era came to an end in 1971, when the peak was climbed in four hours by a party led by J. W. Marchant from the University of Cape Town Mountain and Ski Club. Included were the talented South African climber Gabriel Athiros and Oliver Stansfield from England [2 June 1971]. This team scaled all of the lower pitches without ropes and got through the difficult band without using the artificial steps hacked into the granite. They descended from the peak in two hours and as they reached the base rain began to fall for the first time in over a year. The modern era commenced. E. Haber, together with A. Lombard, C. Ward and Holding completed the first direct ascent of the South West Wall. They began their endeavours in 1977 but did not succeed in finishing the route before 1982. M. Cartwright and M. Hislop freed the route in 1988, giving it a grade of 22, which was later revised to 24. C. Edelstein and G. Mallory left their mark in 1983 by completing \"Royale Flush\", another monster route that was freed only in 2000 by J. Wamsteker and S. Wallis. During 1991 M. Cartwright, K. Smith and M.

(Masaryk in his scientific and political activities paid attention to the development of Czechoslovak universities and since the 1880s he emphasized the need for broad competition in scientific work. In this context, he pointed out that the only Czech university at that time needed a competitive institution for its development.) The founding of the second Czech university was possible only after the fall of the Austro-Hungarian monarchy because of the resistance of the German-controlled city council, which feared giving power to the Czech residents of Brno. Brno was at that time a bilingual city. A notable demonstration in favour of establishing a university in Brno happened in 1905. From the beginning, the university suffered from a lack of money for development. The fragile state of public finances in 1923–1925 and 1933–1934 led to proposals to abolish both the Faculty of Arts and the Faculty of Science. Both faculties eventually survived until 17 November 1939 when the whole university was closed following the German occupation of Czechoslovakia. A number of professors of Masaryk University were executed or tortured; for example, the Faculty of Science lost one quarter of its teaching staff. Many of the executions took place in the Mauthausen concentration camp in 1942. The renewal of university life after the end of World War II was interrupted by the Communist takeover. The percentage of students expelled in various faculties ranged from 5 percent at the Faculty of Education to 46 percent at the Faculty of Law, which was completely closed in 1950. In 1953, the Faculty of Education (founded in 1946) was separated from the university. In August 1960, a government decree abolished the Pharmaceutical Faculty and the University was renamed \"Jan Evangelista Purkyně University in Brno\". Relaxation occurred in 1964 with the reintegration of the Faculty of Education into the university and with the reestablishment of the Faculty of Law in 1969. But conditions changed again rapidly with the Normalization of the 1970s after the 1968 invasion of Warsaw Pact troops into Czechoslovakia.

Another \"Barbel\"-like innovation was the combination of the conning tower, control room, and attack center in one space. This was continued in all subsequent US nuclear submarines. Combining the functions in one space was facilitated by the adoption of \"push-button\" ballast control, another feature of \"Albacore\". Previous designs had routed the trim system piping through the control room, where the valves were manually operated. The \"push-button\" system used hydraulic operators on each valve, remotely electrically operated (actually via toggle switches) from the control room. This greatly conserved control room space and reduced the time required to conduct trim operations. The overall layout made coordination of the weapons and ship control systems easier during combat operations. Much of the overall internal arrangement was continued in the subsequent \"Thresher\"- and \"Sturgeon\"-class submarines. The \"Skipjack\"s' five compartments were called the Torpedo Room, Operations Compartment, Reactor Compartment, Auxiliary Machinery Space (AMS), and Engine Room. With the addition of a missile compartment, the arrangement of the first 41 US nuclear-powered ballistic missile submarines (SSBNs) was similar. The design was primarily single-hull, with a double hull around the torpedo room and AMS for ballast tanks. The design was improved on the \"Thresher\"s, the one-off, and subsequent attack submarines by relocating the torpedo room into the operations compartment via angled midships torpedo tubes to make room for a large sonar sphere in the bow. The \"George Washington\" class, the first SSBNs, were derived from the \"Skipjack\"s, with rebuilt from the incomplete first. The hull of \"Scorpion\" was laid down twice, as the original hull was redesigned to become the \"George Washington\". Also, the material for building was diverted into building, which delayed \"Scamp\"s progress. The bow planes were moved to the massive sail to cut down on flow-induced noise near the bow sonar arrays. They were known as sail planes or fairwater planes. The \"Skipjack\"s were the first class built with sail planes; they were later backfitted on the \"Barbel\"s. This design feature would be repeated on all U.S. nuclear submarines until the improved, the first of which was launched in 1988. The small \"turtleback\" behind the sail was the exhaust piping of the auxiliary diesel generator. The \"Skipjack\"s also introduced the S5W reactor to U.S. nuclear submarines. It was known as ASFR (Advanced Submarine Fleet Reactor) during development. The S5W was used on 98 U.S. nuclear submarines of 8 classes and the first British nuclear submarine,, making it the most-used US Navy reactor design to date.", "section_level": 1}, {"title": "Service.", "content": "\"Skipjack\" was authorized in the FY 1956 new construction program and commissioned in April 1959.

The \"Skipjack\"s remained the fastest US nuclear-powered submarines until the first of the \"Los Angeles\" class entered service in 1974. This was due to the increased size of the \"Thresher\" and \"Sturgeon\" classes, which retained \"Skipjack\"s S5W power plant, plus the introduction of the \"skewback\" screw, which was quiet but mechanically inefficient.

Every word of length formula_18 over an formula_2-ary alphabet corresponds to a node in this tree at depth formula_20. The formula_21th word in the prefix code corresponds to a node formula_22; let formula_23 be the set of all leaf nodes (i.e. of nodes at depth formula_13) in the subtree of formula_11 rooted at formula_22. That subtree being of height formula_27, we have Since the code is a prefix code, those subtrees cannot share any leaves, which means that Thus, given that the total number of nodes at depth formula_13 is formula_31, we have from which the result follows. Conversely, given any ordered sequence of formula_33 natural numbers, satisfying the Kraft inequality, one can construct a prefix code with codeword lengths equal to each formula_35 by choosing a word of length formula_35 arbitrarily, then ruling out all words of greater length that have it as a prefix. There again, we shall interpret this in terms of leaf nodes of an formula_2-ary tree of depth formula_13. First choose any node from the full tree at depth formula_39; it corresponds to the first word of our new code. Since we are building a prefix code, all the descendants of this node (i.e., all words that have this first word as a prefix) become unsuitable for inclusion in the code. We consider the descendants at depth formula_13 (i.e., the leaf nodes among the descendants); there are formula_41 such descendant nodes that are removed from consideration. The next iteration picks a (surviving) node at depth formula_42 and removes formula_43 further leaf nodes, and so on. After formula_33 iterations, we have removed a total of nodes. The question is whether we need to remove more leaf nodes than we actually have available — formula_46 in all — in the process of building the code.

A Major-General commanding the German infantry division of Guards on Foot in France, he was transferred to Finland in March 1918 to help the nationalist government in the civil war against the Finnish \"Reds\" and Soviet Russian troops. He commanded the German expedition unit (\"Baltic Sea Division\") which landed at Hanko, Finland, between 3 April and 5 April 1918, and then marched on the socialist-controlled capital Helsinki, which surrendered after the Battle of Helsinki on 13 April 1918. The German military intervention aided the nationalist government of Finland to gain control over most of the country by May 1918. Goltz stayed with his troops in Finland after the Civil War until December 1918 and was a major political influence in the country, described by the Quartermaster General of the White Army Hannes Ignatius as being the \"true regent of Finland\". In the summer of 1918, Goltz wanted to replace the Finnish White forces with a new Finnish conscript army, where all leadership positions were to be staffed by German officers and conscripts were to be trained according to German army standards. Finnish generals Ignatius, von Gerich and Theslöf resigned from the Finnish military staff in protest. The Germans wanted to use Finnish forces against the Allied units fighting in Murmansk and Arkhangelsk. After the 11 November 1918, armistice, von der Goltz and his division left Helsinki on 16 December 1918. The Inter-Allied Commission of Control insisted that the German troops remain in the Baltic states to prevent the region from being re-occupied by the Red Army. As many of the demoralised German soldiers were being withdrawn from Latvia, a Freikorps unit called the Iron Division (\"Eiserne Division\") was formed and deployed in Riga and used to delay the Red advance. New volunteers arriving from Germany and remnants of the German 8th Army were subsequently added to the Iron Division, which was assigned under the command of Goltz. Also, Baltic Germans and some Latvians formed the \"Baltische Landeswehr\", led by Major Alfred Fletcher. In late February 1919, only the seaport of Libau (Liepāja) remained in the hands of the German and Latvian forces. In March 1919, General von der Goltz was able to win a series of victories over the Red Army, first occupying Windau (Ventspils), the major port of Courland, and then advancing south and east to retake Riga. After the Bolsheviks had been driven out from most of Latvia, the Allies ordered the German government to withdraw its troops from the Baltic region. However, the Germans succeeded in negotiating a postponement, arguing that this would have given the Bolsheviks a free hand. General von der Goltz then attempted to seize control of Latvia with the assistance of the local German population. The Latvian nationalist government was deposed while the Freikorps, Latvian and White Russian units moved on to capture Riga on May 23, 1919. The Latvian nationalists sought assistance from the Estonian army which had been occupying northern Latvia since earlier that year. In June 1919, General von der Goltz ordered his troops not to advance east against the Red Army, as the Allies had been expecting, but north, against the Estonians. On June 19, the Iron Division and \"Landeswehr\" units launched an attack to capture areas around Wenden (Cēsis), but in the battles over the following few days, they were defeated by the 3rd Estonian Division (led by Ernst Põdder). On the morning of June 23, the Germans began a general retreat toward Riga. The Allies again insisted that the Germans withdraw their remaining troops from Latvia and intervened to impose a ceasefire between the Estonians and the Freikorps when the Latvians were about to march into Riga. The British insisted that General von der Goltz leave Latvia, and he turned his troops over to the West Russian Volunteer Army. Count von der Goltz later claimed in his memoirs that his major strategic goal in 1919 had been to launch a campaign in cooperation with the White Russian forces to overturn the Bolshevik regime by marching on St. Petersburg and to install a pro-German anti-Bolshevist government in Russia. As President of the United Patriotic Organizations he participated in the Harzburg Front in the early thirties. From 1924 to 1930, he headed the German government department on the military education of young German youth. On 17 July 1931 he handed over the command of the Economic Policy Association Frankfurt am Main to the Reich President Paul von Hindenburg.

This technique removes both nutrients and soil cover from the site and so can be harmful to the long term health of the area if no further action is taken, however, depending on the species, many of the limbs are often broken off in handling so the end result may not be as different from tree-length logging as it might seem.", "section_level": 2}, {"title": "Cut-to-length logging.", "content": "Cut-to-length logging is the process of felling, delimbing, bucking, and sorting (pulpwood, sawlog, etc.) at the stump area, leaving limbs and tops in the forest.

Many methods have been used to move logs from where they were cut to a rail line or directly to a sawmill or paper mill. The cheapest and historically most common method is making use of a river's current to float floating tree trunks downstream, by either log driving or timber rafting. (Some logs sink because of high resin content; these are called deadheads.) To help herd the logs to the mill, in 1960 the Alaskan Lumber and Pulp Mill had a specially designed boat that was constructed of steel. In the late 1800s and the first half of the 1900s, the most common method was the high-wheel loader, which was a set of wheels over ten feet tall that the log or logs were strapped beneath. Oxen were at first used with the high-wheel loaders, but in the 1930s tractors replaced the oxen. In 1960 the largest high wheel loader was built for service in California. Called the Bunyan Buggie, the unit was self-propelled and had wheels high and a front dozer blade that was across and high. Log transportation can be challenging and costly since trees are often far from roads or watercourses. Road building and maintenance may be restricted in National Forests or other wilderness areas since it can cause erosion in riparian zones. When felled logs sit adjacent to a road, heavy machinery may simply lift logs onto trucks. Most often, special heavy equipment is used to gather the logs from the site and move them close to the road to be lifted on trucks. Many methods exist to transport felled logs lying away from roads. Cable logging involves a yarder, which pulls one or several logs along the ground to a platform where a truck is waiting. When the terrain is too uneven to pull logs on the ground, a skyline can lift logs off the ground vertically, similar to a ski lift. Heli-logging, which uses heavy-lift helicopters to remove cut trees from forests by lifting them on cables attached to a helicopter, may be used when cable logging is not allowed for environmental reasons or when roads are lacking. It reduces the level of infrastructure required to log in a specific location, reducing the environmental impact of logging. Less mainstream or now for the most part superseded forms of log transport include horses, oxen, or balloon logging.", "section_level": 1}, {"title": "Safety considerations.", "content": "Logging is a dangerous occupation. In the United States, it has consistently been one of the most hazardous industries and was recognized by the National Institute for Occupational Safety and Health (NIOSH) as a priority industry sector in the National Occupational Research Agenda (NORA) to identify and provide intervention strategies regarding occupational health and safety issues. In 2008, the logging industry employed 86,000 workers, and accounted for 93 deaths. This resulted in a fatality rate of 108.1 deaths per 100,000 workers that year. This rate is over 30 times higher than the overall fatality rate. Forestry/logging-related injuries (fatal and non-fatal) are often difficult to track through formal reporting mechanisms. Thus, some programs have begun to monitor injuries through publicly available reports such as news media. The logging industry experiences the highest fatality rate of 23.2 per 100,000 full-time equivalent (FTE) workers and a non-fatal incident rate of 8.5 per 100 FTE workers. The most common type of injuries or illnesses at work include musculoskeletal disorders (MSDs), which include an extensive list of \"inflammatory and degenerative conditions affecting the muscles, tendons, ligaments, joints, peripheral nerves, and supporting blood vessels.\" Loggers work with heavy, moving weights, and use tools such as chainsaws and heavy equipment on uneven and sometimes steep or unstable terrain. Loggers also deal with severe environmental conditions, such as inclement weather and severe heat or cold. An injured logger is often far from professional emergency treatment. Traditionally, the cry of \"Timber!\" developed as a warning alerting fellow workers in an area that a tree is being felled, so they should be alert to avoid being struck. The term \"widowmaker\" for timber that is neither standing nor fallen to the ground demonstrates another emphasis on situational awareness as a safety principle. In British Columbia, Canada, the BC Forest Safety Council was created in September 2004 as a not-for-profit society dedicated to promoting safety in the forest sector. It works with employers, workers, contractors, and government agencies to implement fundamental changes necessary to make it safer to earn a living in forestry.

He was the son of Jošt III of Rosenberg and his second wife Anna of Roggendorf (d. 1562). His father died when William was four years old. William and his younger brother Peter Vok then stood under the guardianship of their uncle Peter V. From age seven, he studied at the Protestant private school of Arnošt Kraiger von Kraigk in Mlada Boleslav. In 1544, at the age of nine, he switched to a Catholic school for young nobles at the court of Bishop Wolfgang of Passau. On 23 April 1551, at the age of sixteen, William was declared an adult by a decree of Emperor Ferdinand I. He took up the administration of the family's possessions and chose as his residence Český Krumlov Castle, which he remodeled in a Renaissance style. From 1552 to 1556, he fought a court case against Henry IV of Plauen, the High Chancellor of Bohemia, about their precedence in Bohemian society. William won. In 1560, he was appointed High Treasurer by King Ferdinand. In 1566, he was appointed commander of the Bohemian army and on 10 June 1566, he began forming an army at Znojmo to fight a war against the Ottoman Empire. Their aim was to recapture Szigetvár, which William's brother-in-law Nikola Šubić Zrinski had lost to the Turks. The Habsburg armies were to meet at Győr. However, the Turks retreated south after the death of Suleiman the Magnificent and no battle ensued. On 26 May 1570, William was appointed High Burgrave of Bohemia, the highest office in the Kingdom. In this position, he was repeatedly given diplomatic duties, for example, he was sent to Germany twice. In 1572, he negotiated with Emperor Maximilian II, the leader of the Holy League about the next step to take in the ongoing war with then Ottoman Empire. In 1574, he was involved in the negotiations about electing King Rudolf II of Bohemia as the new emperor. In Poland, he represented the interests of Archduke Ernest of Austria, who aimed to be elected King of Poland. His efforts were in vain, although he gained so much sympathy that when King Henry fled, he was considered as a candidate to be the next king. As it happened, King Rudolf was also interested and out of loyalty, William withdrew. Eventually Stephen Bathory, a Transylvanian prince, was elected. However, he died shortly after his election. William was honored with the order of the Golden Fleece for his diplomatic mediation. In 1587, Sigismund III Vasa was elected as the new King of Poland, defeating the Habsburg candidate Maximilian III. Maximilian then tried to grab power in Poland by invading the country. His army was defeated by the Polish general Jan Zamoyski and he was taken prisoner. William was sent to Poland to negotiate his release. These negotiations led to a peace treaty in March 1589, and Maximilian's release. In addition to his high political office, William was actively promoting science, literature, music and architecture. Both he and his younger brother Peter Vok acted as patrons of the arts. They supported the Charles University in Prague and founded secondary schools in their territories. They created a library with a vast collection of precious manuscripts and incunables. With its approximately volumes, it was one of the largest libraries of its time. Many humanists such as the Flemish mineralogist, physician and naturalist Anselmus de Boodt were active at his court. William also supported economic and cultural development in his territories. His Třeboň Castle was expanded and remodeled in a renaissance style by the architect Antonio Ericer between 1565 and 1575. He added the southwest wing, a tower and the entrance gate. In 1573, William expanded the Rosenberg Palace his uncle Peter V had built inside the Prague Castle, using designs made by the architect Ulrico Aostalli. In the town of Roudnice nad Labem, which he acquired in 1577, he renewed the castle and the bridge across the Elbe. In 1580, William exchanged some territory with his business manager Jakub Krčín of Jelčan: he transferred Sedlčany and Křepenice to Jakub and received a large deer parc and the Leptáč manor near Netolice in return. Between 1583 and 1589, William built his Kratochvíle Castle at Netolice. This castle is one of the most important Renaissance buildings in southern Bohemia. In 1584, he invited the Jesuits to his Český Krumlov Castle and between 1586 and 1588, they constructed a large college building there. The castle, which was his main residence, was extensively remodeled during his reign and he equipped a number of state rooms in the upper castle. In 1580, he added a tower, connected to the castle with a Renaissance arcade. In 1589 he took part in the negotiations of the Treaty of Bytom and Będzin. Around 1590, he added the Little Castle. He gave town rights to Borovany, which was located in his land, and in Libějovice he expanded the old castle into another renaissance castle. In Třeboň, he promoted carp breeding and constructed the Rožmberk Pond. William died in 1592 and was buried in the St. Vitus Church in Český Krumlov, next to his third wife, Anna Maria of Baden.

At the urging of his brother Prince Albert, Hereditary Prince Ernst of Saxe-Coburg and Gotha (born 1818) began to search for a suitable bride. Albert believed that a wife would be good for his brother: \"Chains you will have to bear in any case, and it will certainly be good for you... The heavier and tighter they are, the better for you. A married couple must be chained to one another, be inseparable, and they must live only for one another.\" With this advice in mind (although Albert was reprimanded for presuming to counsel his elders), Ernest began searching. Around this time, Ernest was suffering from a venereal disease brought on by his many affairs; Albert consequently counseled him against marrying until he was fully recovered. He also warned that continued promiscuity could leave Ernest unable to father children. Ernest waited a few years before marrying as a result. On 13 May 1842, in Karlsruhe, Ernest married Princess Alexandrine. To the consternation of his brother and sister-in-law Queen Victoria, the marriage failed to \"settle down\" Ernest.

While touring some farms in Windsor, Alexandrine caught a cold; they left soon after. Lady Eleanor commented again that \"[Alexandrine] was very sweet at parting, and kissed us all round; she looked very delicate, as white as a sheet, and more fit to be in her bed than undertaking a long journey. The parting of the Royalty was not so sorrowful as I expected; plenty of kissing, but no tears\". Victoria was sorry to see them leave, as she loved Ernest loyally for Albert's sake, and had come to see Alexandrine as a sister. Victoria chose Ernest to be the godfather of her second daughter Princess Alice, and he was consequently expected in England in April 1859 for her confirmation. Though Victoria was eager to see his wife again, and though plans had been arranged the previous year for her to visit, Ernest chose to not bring her along. It was clear that as the chances of producing children had faded, Ernest was taking less and less interest in his wife. The marriage proved to be childless.

This new material was the Poly(2-hydroxyethyl methacrylate) (pHEMA), that they patented in 1953. Wichterle thought pHEMA might be a suitable material for contact lenses and gained his first patent for soft contact lenses. On 1954 this material was first used as an orbital implant. On 1957 Wichterle produced around 100 soft lenses from closed polystyrene molds but the edges split and tore as the lenses were removed. In addition, they required hand finishing. He was determined to find a better way. Unfortunately, Wichterle and other prominent teachers had to leave the Institute of Chemical Technology after a political purge staged by its Communist leadership 1958. Research into contact eye lenses at the Institute of Chemical Technology came to an end. The International Symposium on Macromolecular Chemistry held in Prague in 1957 convinced the state leadership of the need to establish a centre for research into synthetic polymers. The Institute of Macromolecular Chemistry of the Czechoslovak Academy of Sciences (CSAS) came into being in 1958, with Professor Wichterle appointed its director.

On Christmas afternoon, with the help of his wife Linda, using the machine on his kitchen table, he finally succeeded. He tried the lenses in his own eyes and although they were the wrong power they were comfortable. Thus, he invented a new way of manufacturing the lenses using a centrifugal casting procedure. A few days later, he completed his patent application and produced over 100 lenses by spin casting. He built several new prototype machines using Merkur toys with increasing numbers of spindles which required the stronger motor taken from his gramophone. With these rudimental devices, in the first four months of 1962 they made 5,500 lenses. The early experimental lenses were called Geltakt and the later production lenses Spofalens after the state enterprise SPOFA which manufactured them.

Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands. Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. The \"Kikka\" was designed in preliminary form to use the Tsu-11, a very crude motorjet style of jet engine that was little more than a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003. Development of the engine was troublesome, based on little more than photographs and a cut-away drawing; but a suitable unit, the Ishikawajima Ne-20, was finally built. By mid-1945, the \"Kikka\" project was making progress once again and at this stage, reflecting the deteriorating war situation, it is possible that the Navy considered employing the \"Kikka\" as a \"kamikaze\" weapon although the prospect was questionable due to the high cost and complexity associated with contemporary turbojet engines. As well, other more economical projects meant specifically for the role such as the simple Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production. Compared to the Me 262, the \"Kikka\" airframe was noticeably smaller and even more conventional in design, with straight wings (lacking the slight sweepback of the Me 262) and tail surfaces. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks.

The first flight took place on 7 August 1945 (the day after Hiroshima was bombed by atomic bomb), with Lieutenant Commander Susumu Takaoka at the controls. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run. For the second test flight, four days later (4 days prior to Japan's declaration of surrender), rocket assisted take off (RATO) units were fitted to the aircraft. The pilot had been uneasy about the angle at which the rocket tubes had been set, but with no time to correct them they decided to simply reduce the thrust of the rockets from 800 kg to only 400 kg. Four seconds into take off the RATO was actuated, immediately jolting the aircraft back onto its tail leaving the pilot with no effective tail control. After the nine-second burning time of the RATO ran out the nose came down and the nose wheel contacted the runway, resulting in a sudden deceleration, however both engines were still functioning normally. At this point the pilot opted to abort the take off, but fighting to brake the aircraft and perform a ground loop only put him in danger of running it into other installations. Eventually the aircraft ran over a drainage ditch which caught the tricycle landing gear, the aircraft continued to skid forward and stopped short of the water's edge. Before it could be repaired Japan had surrendered and the war was over. At this point, the second prototype was close to completion, and approximately 23 more airframes were under construction.

Eight princely abbeys (including similar status priories) and roughly 40 imperial abbeys survived up to the mass secularisation of 1802–03 when they were all secularized. The head of an Imperial abbey was generally an Imperial abbot (\"Reichsabt\") or Imperial abbess (\"Reichsäbtissin\"). (The head of a \"Reichspropstei\"—an Imperial provostry or priory—was generally a \"Reichspropst\"). Collectively, Imperial abbots, provosts and priors were formally known as \"Reichsprälaten\" (Imperial Prelates). A small number of the larger and most prestigious establishments had the rank of princely abbeys (\"Fürstsabtei\"), and were headed by a prince-abbot or a prince-provost (\"Fürstabt\", \"Fürstpropst\"), with status comparable to that of Prince-Bishops. Most however were imperial prelates and as such participated in a single collective vote in the Imperial Diet as members of the Bench of Prelates, later (1575) divided into the Swabian College of Imperial Prelates and the Rhenish College of Imperial Prelates. Despite their difference of status within the Imperial Diet, both the Imperial Prelates and the Prince-Abbots exercised the same degree of authority over their principality. Some abbeys, particularly in Switzerland, gained the status of princely abbeys (\"Fürstsabtei\") during the Middle Ages or later but they either didn't have a territory over which they ruled or they lost that territory after a short while. This was the case with Kreuzlingen, Allerheiligen, Einsiedeln, Muri and Saint-Maurice abbeys. One major exception was the large and powerful Abbey of St. Gall which remained independent up to its dissolution during the Napoleonic period, despite the fact that, as a Swiss abbey, it had stopped taking part in the Imperial Diet and other institutions of the Holy Roman Empire once the independence of the Swiss Confederacy was recognized in 1648.

He was one of three children. His father, a clerk in a land surveying office, died when he was seven, and his mother moved to Kazan. Lobachevsky attended Kazan Gymnasium from 1802, graduating in 1807 and then received a scholarship to Kazan University, which was founded just three years earlier in 1804. At Kazan University, Lobachevsky was influenced by professor Johann Christian Martin Bartels, a former teacher and friend of German mathematician Carl Friedrich Gauss. Lobachevsky received a master's degree in physics and mathematics in 1811. In 1814, he became a lecturer at Kazan University, in 1816 he was promoted to associate professor. In 1822, at the age of 30, he became a full professor, teaching mathematics, physics, and astronomy. He served in many administrative positions and became the rector of Kazan University in 1827. In 1832, he married Varvara Alexeyevna Moiseyeva. They had a large number of children (eighteen according to his son's memoirs, while only seven apparently survived into adulthood). He was dismissed from the university in 1846, ostensibly due to his deteriorating health: by the early 1850s, he was nearly blind and unable to walk. He died in poverty in 1856.

Before him, mathematicians were trying to deduce Euclid's fifth postulate from other axioms. Euclid's fifth is a rule in Euclidean geometry which states (in John Playfair's reformulation) that for any given line and point not on the line, there is only one line through the point not intersecting the given line. Lobachevsky would instead develop a geometry in which the fifth postulate was not true. This idea was first reported on February 23 (Feb. 11, O.S.), 1826 to the session of the department of physics and mathematics, and this research was printed in the UMA (Вестник Казанского университета) in 1829–1830. Lobachevsky wrote a paper about it called \"A concise outline of the foundations of geometry\" that was published by the \"Kazan Messenger\" but was rejected when it was submitted to the St. Petersburg Academy of Sciences for publication. The non-Euclidean geometry that Lobachevsky developed is referred to as hyperbolic geometry. Lobachevsky replaced Playfair's axiom with the statement that for any given point there exists \"more than\" one line that can be extended through that point and run parallel to another line of which that point is not part. He developed the angle of parallelism which depends on the distance the point is off the given line. In hyperbolic geometry the sum of angles in a hyperbolic triangle must be less than 180 degrees. Non-Euclidean geometry stimulated the development of differential geometry which has many applications. Hyperbolic geometry is frequently referred to as \"Lobachevskian geometry\" or \"Bolyai–Lobachevskian geometry\". Some mathematicians and historians have wrongfully claimed that Lobachevsky in his studies in non-Euclidean geometry was influenced by Gauss, which is untrue. Gauss himself appreciated Lobachevsky's published works very highly, but they never had personal correspondence between them prior to the publication. Although three people—Gauss, Lobachevsky and Bolyai—can be credited with discovery of hyperbolic geometry, Gauss never published his ideas, and Lobachevsky was the first to present his views to the world mathematical community. Lobachevsky's magnum opus \"Geometriya\" was completed in 1823, but was not published in its exact original form until 1909, long after he had died. Lobachevsky was also the author of \"New Foundations of Geometry\" (1835–1838). He also wrote \"Geometrical Investigations on the Theory of Parallels\" (1840) and \"Pangeometry\" (1855). Another of Lobachevsky's achievements was developing a method for the approximation of the roots of algebraic equations. This method is now known as the Dandelin–Gräffe method, named after two other mathematicians who discovered it independently. In Russia, it is called the Lobachevsky method. Lobachevsky gave the definition of a function as a correspondence between two sets of real numbers (Peter Gustav Lejeune Dirichlet gave the same definition independently soon after Lobachevsky).", "section_level": 1}, {"title": "Impact.", "content": "E.

The full impact of the Lobachevskian method of challenging axioms has probably yet to be felt.
