University of Chicago scholars have played a major role in the development of various academic disciplines, including: the Chicago school of economics, the Chicago school of sociology, the law and economics movement in legal analysis, the Chicago school of literary criticism, the Chicago school of religion, and the behavioralism school of political science. Chicago's physics department helped develop the world's first man-made, self-sustaining nuclear reaction beneath the university's Stagg Field. Chicago's research pursuits have been aided by unique affiliations with world-renowned institutions like the nearby Fermilab and Argonne National Laboratory, as well as the Marine Biological Laboratory. The university is also home to the University of Chicago Press, the largest university press in the United States. With an estimated completion date of 2020, the Barack Obama Presidential Center will be housed at the university and include both the Obama presidential library and offices of the Obama Foundation.

In 1929, the university's fifth president, Robert Maynard Hutchins, took office; the university underwent many changes during his 24-year tenure. Hutchins eliminated varsity football from the university in an attempt to emphasize academics over athletics, instituted the undergraduate college's liberal-arts curriculum known as the Common Core, and organized the university's graduate work into its current[when?] four divisions. In 1933, Hutchins proposed an unsuccessful plan to merge the University of Chicago and Northwestern University into a single university. During his term, the University of Chicago Hospitals (now called the University of Chicago Medical Center) finished construction and enrolled its first medical students. Also, the Committee on Social Thought, an institution distinctive of the university, was created.

What was the name given to the undergraduate college's liberal-arts curriculum?

Many major classes of organic molecules in living organisms, such as proteins, nucleic acids, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that are constituents of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as it is a part of water, the major constituent of lifeforms. Oxygen is used in cellular respiration and released by photosynthesis, which uses the energy of sunlight to produce oxygen from water. It is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone (O
3), strongly absorbs UVB radiation and consequently the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation, but is a pollutant near the surface where it is a by-product of smog. At even higher low earth orbit altitudes, sufficient atomic oxygen is present to cause erosion for spacecraft.

What element is found in most organic organisms?


The relationship of ctenophores to the rest of Metazoa is very important to our understanding of the early evolution of animals and the origin of multicellularity. It has been the focus of debate for many years. Ctenophores have been purported to be the sister lineage to the Bilateria, sister to the Cnidaria, sister to Cnidaria, Placozoa and Bilateria, and sister to all other animal phyla. A series of studies that looked at the presence and absence of members of gene families and signalling pathways (e.g., homeoboxes, nuclear receptors, the Wnt signaling pathway, and sodium channels) showed evidence congruent with the latter two scenarios, that ctenophores are either sister to Cnidaria, Placozoa and Bilateria or sister to all other animal phyla. Several more recent studies comparing complete sequenced genomes of ctenophores with other sequenced animal genomes have also supported ctenophores as the sister lineage to all other animals. This position would suggest that neural and muscle cell types were either lost in major animal lineages (e.g., Porifera) or that they evolved independently in the ctenophore lineage. However, other researchers have argued that the placement of Ctenophora as sister to all other animals is a statistical anomaly caused by the high rate of evolution in ctenophore genomes, and that Porifera (sponges) is the earliest-diverging animal phylum instead. Ctenophores and sponges are also the only known animal phyla that lack any true hox genes.
How do other researchers believe Porifera evolved and developed its neural cells? (If the question is unanswerable, say "unanswerable")


From here, the situation becomes more complicated, as the Dutch name Rijn no longer coincides with the main flow of water. Two thirds of the water flow volume of the Rhine flows farther west, through the Waal and then, via the Merwede and Nieuwe Merwede (De Biesbosch), merging with the Meuse, through the Hollands Diep and Haringvliet estuaries, into the North Sea. The Beneden Merwede branches off, near Hardinxveld-Giessendam and continues as the Noord, to join the Lek, near the village of Kinderdijk, to form the Nieuwe Maas; then flows past Rotterdam and continues via Het Scheur and the Nieuwe Waterweg, to the North Sea. The Oude Maas branches off, near Dordrecht, farther down rejoining the Nieuwe Maas to form Het Scheur.

While the existence of these central government departments and the Six Ministries (which had been introduced since the Sui and Tang dynasties) gave a Sinicized image in the Yuan administration, the actual functions of these ministries also reflected how Mongolian priorities and policies reshaped and redirected those institutions. For example, the authority of the Yuan legal system, the Ministry of Justice, did not extend to legal cases involving Mongols and Semuren, who had separate courts of justice. Cases involving members of more than one ethnic group were decided by a mixed board consisting of Chinese and Mongols. Another example was the insignificance of the Ministry of War compared with native Chinese dynasties, as the real military authority in Yuan times resided in the Privy Council.

Economic inequality:

In 2014, economists with the Standard & Poor's rating agency concluded that the widening disparity between the U.S.'s wealthiest citizens and the rest of the nation had slowed its recovery from the 2008-2009 recession and made it more prone to boom-and-bust cycles. To partially remedy the wealth gap and the resulting slow growth, S&P recommended increasing access to education. It estimated that if the average United States worker had completed just one more year of school, it would add an additional $105 billion in growth to the country's economy over five years.

On 8 February 2007, BSkyB announced its intention to replace its three free-to-air digital terrestrial channels with four subscription channels. It was proposed that these channels would offer a range of content from the BSkyB portfolio including sport (including English Premier League Football), films, entertainment and news. The announcement came a day after Setanta Sports confirmed that it would launch in March as a subscription service on the digital terrestrial platform, and on the same day that NTL's services re-branded as Virgin Media. However, industry sources believe BSkyB will be forced to shelve plans to withdraw its channels from Freeview and replace them with subscription channels, due to possible lost advertising revenue.

When did Setanta Sports say it would launch as a free service on the digital terrestrial platform?


The Standard Industrial Classification and the newer North American Industry Classification System have a classification system for companies that perform or otherwise engage in construction. To recognize the differences of companies in this sector, it is divided into three subsectors: building construction, heavy and civil engineering construction, and specialty trade contractors. There are also categories for construction service firms (e.g., engineering, architecture) and construction managers (firms engaged in managing construction projects without assuming direct financial responsibility for completion of the construction project).
Try to answer this question if possible (otherwise reply "unanswerable"): What are construction managers?


Immunodeficiencies occur when one or more of the components of the immune system are inactive. The ability of the immune system to respond to pathogens is diminished in both the young and the elderly, with immune responses beginning to decline at around 50 years of age due to immunosenescence. In developed countries, obesity, alcoholism, and drug use are common causes of poor immune function. However, malnutrition is the most common cause of immunodeficiency in developing countries. Diets lacking sufficient protein are associated with impaired cell-mediated immunity, complement activity, phagocyte function, IgA antibody concentrations, and cytokine production. Additionally, the loss of the thymus at an early age through genetic mutation or surgical removal results in severe immunodeficiency and a high susceptibility to infection.

Answer this question, if possible (if impossible, reply "unanswerable"): In what people is the immune system the strongest?


Geology:

James Hutton is often viewed as the first modern geologist. In 1785 he presented a paper entitled Theory of the Earth to the Royal Society of Edinburgh. In his paper, he explained his theory that the Earth must be much older than had previously been supposed in order to allow enough time for mountains to be eroded and for sediments to form new rocks at the bottom of the sea, which in turn were raised up to become dry land. Hutton published a two-volume version of his ideas in 1795 (Vol. 1, Vol. 2).

Economic inequality:

An important factor in the creation of inequality is variation in individuals' access to education. Education, especially in an area where there is a high demand for workers, creates high wages for those with this education, however, increases in education first increase and then decrease growth as well as income inequality. As a result, those who are unable to afford an education, or choose not to pursue optional education, generally receive much lower wages. The justification for this is that a lack of education leads directly to lower incomes, and thus lower aggregate savings and investment. Conversely, education raises incomes and promotes growth because it helps to unleash the productive potential of the poor.

are prime. Prime numbers of this form are known as factorial primes. Other primes where either p + 1 or p − 1 is of a particular shape include the Sophie Germain primes (primes of the form 2p + 1 with p prime), primorial primes, Fermat primes and Mersenne primes, that is, prime numbers that are of the form 2p − 1, where p is an arbitrary prime. The Lucas–Lehmer test is particularly fast for numbers of this form. This is why the largest known prime has almost always been a Mersenne prime since the dawn of electronic computers.

What test is especially useful for tests of the form 2p-1?


Phagocytosis is an important feature of cellular innate immunity performed by cells called 'phagocytes' that engulf, or eat, pathogens or particles. Phagocytes generally patrol the body searching for pathogens, but can be called to specific locations by cytokines. Once a pathogen has been engulfed by a phagocyte, it becomes trapped in an intracellular vesicle called a phagosome, which subsequently fuses with another vesicle called a lysosome to form a phagolysosome. The pathogen is killed by the activity of digestive enzymes or following a respiratory burst that releases free radicals into the phagolysosome. Phagocytosis evolved as a means of acquiring nutrients, but this role was extended in phagocytes to include engulfment of pathogens as a defense mechanism. Phagocytosis probably represents the oldest form of host defense, as phagocytes have been identified in both vertebrate and invertebrate animals.

Seismologists can use the arrival times of seismic waves in reverse to image the interior of the Earth. Early advances in this field showed the existence of a liquid outer core (where shear waves were not able to propagate) and a dense solid inner core. These advances led to the development of a layered model of the Earth, with a crust and lithosphere on top, the mantle below (separated within itself by seismic discontinuities at 410 and 660 kilometers), and the outer core and inner core below that. More recently, seismologists have been able to create detailed images of wave speeds inside the earth in the same way a doctor images a body in a CT scan. These images have led to a much more detailed view of the interior of the Earth, and have replaced the simplified layered model with a much more dynamic model.

Read this: After this, Huguenots (with estimates ranging from 200,000 to 1,000,000) fled to surrounding Protestant countries: England, the Netherlands, Switzerland, Norway, Denmark, and Prussia — whose Calvinist Great Elector Frederick William welcomed them to help rebuild his war-ravaged and underpopulated country. Following this exodus, Huguenots remained in large numbers in only one region of France: the rugged Cévennes region in the south. In the early 18th century, a regional group known as the Camisards who were Huguenots rioted against the Catholic Church in the region, burning churches and killing clergy. It took French troops years to hunt down and destroy all the bands of Camisards, between 1702 and 1709.

In the China of the Yuan, or Mongol era, various important developments in the arts occurred or continued in their development, including the areas of painting, mathematics, calligraphy, poetry, and theater, with many great artists and writers being famous today. Due to the coming together of painting, poetry, and calligraphy at this time many of the artists practicing these different pursuits were the same individuals, though perhaps more famed for one area of their achievements than others. Often in terms of the further development of landscape painting as well as the classical joining together of the arts of painting, poetry, and calligraphy, the Song dynasty and the Yuan dynasty are linked together. In the area of Chinese painting during the Yuan dynasty there were many famous painters. In the area of calligraphy many of the great calligraphers were from the Yuan dynasty era. In Yuan poetry, the main development was the qu, which was used among other poetic forms by most of the famous Yuan poets. Many of the poets were also involved in the major developments in the theater during this time, and the other way around, with people important in the theater becoming famous through the development of the sanqu type of qu. One of the key factors in the mix of the zaju variety show was the incorporation of poetry both classical and of the newer qu form. One of the important cultural developments during the Yuan era was the consolidation of poetry, painting, and calligraphy into a unified piece of the type that tends to come to mind when people think of classical Chinese art. Another important aspect of Yuan times is the increasing incorporation of the then current, vernacular Chinese into both the qu form of poetry and the zaju variety show. Another important consideration regarding Yuan dynasty arts and culture is that so much of it has survived in China, relatively to works from the Tang dynasty and Song dynasty, which have often been better preserved in places such as the Shōsōin, in Japan.

What type of languages flourished in the Yuan?


Imperialism:

According to geographic scholars under colonizing empires, the world could be split into climatic zones. These scholars believed that Northern Europe and the Mid-Atlantic temperate climate produced a hard-working, moral, and upstanding human being. Alternatively, tropical climates yielded lazy attitudes, sexual promiscuity, exotic culture, and moral degeneracy. The people of these climates were believed to be in need of guidance and intervention from the European empire to aid in the governing of a more evolved social structure; they were seen as incapable of such a feat. Similarly, orientalism is a view of a people based on their geographical location.

European Union law:

Today, the Treaty of Lisbon prohibits anti-competitive agreements in Article 101(1), including price fixing. According to Article 101(2) any such agreements are automatically void. Article 101(3) establishes exemptions, if the collusion is for distributional or technological innovation, gives consumers a "fair share" of the benefit and does not include unreasonable restraints that risk eliminating competition anywhere (or compliant with the general principle of European Union law of proportionality). Article 102 prohibits the abuse of dominant position, such as price discrimination and exclusive dealing. Article 102 allows the European Council to regulations to govern mergers between firms (the current regulation is the Regulation 139/2004/EC). The general test is whether a concentration (i.e. merger or acquisition) with a community dimension (i.e. affects a number of EU member states) might significantly impede effective competition. Articles 106 and 107 provide that member state's right to deliver public services may not be obstructed, but that otherwise public enterprises must adhere to the same competition principles as companies. Article 107 lays down a general rule that the state may not aid or subsidise private parties in distortion of free competition and provides exemptions for charities, regional development objectives and in the event of a natural disaster.

In the meantime, on August 1, 1774, an experiment conducted by the British clergyman Joseph Priestley focused sunlight on mercuric oxide (HgO) inside a glass tube, which liberated a gas he named "dephlogisticated air". He noted that candles burned brighter in the gas and that a mouse was more active and lived longer while breathing it. After breathing the gas himself, he wrote: "The feeling of it to my lungs was not sensibly different from that of common air, but I fancied that my breast felt peculiarly light and easy for some time afterwards." Priestley published his findings in 1775 in a paper titled "An Account of Further Discoveries in Air" which was included in the second volume of his book titled Experiments and Observations on Different Kinds of Air. Because he published his findings first, Priestley is usually given priority in the discovery.

By sunlight, what compound did  Priestley concentrate on to make the gas he called "dephlogisticated air"?

Clearly, some tumors evade the immune system and go on to become cancers. Tumor cells often have a reduced number of MHC class I molecules on their surface, thus avoiding detection by killer T cells. Some tumor cells also release products that inhibit the immune response; for example by secreting the cytokine TGF-β, which suppresses the activity of macrophages and lymphocytes. In addition, immunological tolerance may develop against tumor antigens, so the immune system no longer attacks the tumor cells.

What receptors do tumor cells often have reduced concentrations of?


Read this: Gamma delta T cells (γδ T cells) possess an alternative T cell receptor (TCR) as opposed to CD4+ and CD8+ (αβ) T cells and share the characteristics of helper T cells, cytotoxic T cells and NK cells. The conditions that produce responses from γδ T cells are not fully understood. Like other 'unconventional' T cell subsets bearing invariant TCRs, such as CD1d-restricted Natural Killer T cells, γδ T cells straddle the border between innate and adaptive immunity. On one hand, γδ T cells are a component of adaptive immunity as they rearrange TCR genes to produce receptor diversity and can also develop a memory phenotype. On the other hand, the various subsets are also part of the innate immune system, as restricted TCR or NK receptors may be used as pattern recognition receptors. For example, large numbers of human Vγ9/Vδ2 T cells respond within hours to common molecules produced by microbes, and highly restricted Vδ1+ T cells in epithelia respond to stressed epithelial cells.

The weak force is due to the exchange of the heavy W and Z bosons. Its most familiar effect is beta decay (of neutrons in atomic nuclei) and the associated radioactivity. The word "weak" derives from the fact that the field strength is some 1013 times less than that of the strong force. Still, it is stronger than gravity over short distances. A consistent electroweak theory has also been developed, which shows that electromagnetic forces and the weak force are indistinguishable at a temperatures in excess of approximately 1015 kelvins. Such temperatures have been probed in modern particle accelerators and show the conditions of the universe in the early moments of the Big Bang.

What force is weaker than gravity over short distances?

Rhine:

Until the early 1980s, industry was a major source of water pollution. Although many plants and factories can be found along the Rhine up into Switzerland, it is along the Lower Rhine that the bulk of them are concentrated, as the river passes the major cities of Cologne, Düsseldorf and Duisburg. Duisburg is the home of Europe's largest inland port and functions as a hub to the sea ports of Rotterdam, Antwerp and Amsterdam. The Ruhr, which joins the Rhine in Duisburg, is nowadays a clean river, thanks to a combination of stricter environmental controls, a transition from heavy industry to light industry and cleanup measures, such as the reforestation of Slag and brownfields. The Ruhr currently provides the region with drinking water. It contributes 70 m3/s (2,500 cu ft/s) to the Rhine. Other rivers in the Ruhr Area, above all, the Emscher, still carry a considerable degree of pollution.

When Céloron's expedition arrived at Logstown, the Native Americans in the area informed Céloron that they owned the Ohio Country and that they would trade with the British regardless of the French. Céloron continued south until his expedition reached the confluence of the Ohio and the Miami rivers, which lay just south of the village of Pickawillany, the home of the Miami chief known as "Old Briton". Céloron threatened "Old Briton" with severe consequences if he continued to trade with the British. "Old Briton" ignored the warning. Disappointed, Céloron returned to Montreal in November 1749.

Read this: The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body under the auspices of the United Nations, set up at the request of member governments. It was first established in 1988 by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), and later endorsed by the United Nations General Assembly through Resolution 43/53. Membership of the IPCC is open to all members of the WMO and UNEP. The IPCC produces reports that support the United Nations Framework Convention on Climate Change (UNFCCC), which is the main international treaty on climate change. The ultimate objective of the UNFCCC is to "stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic [i.e., human-induced] interference with the climate system". IPCC reports cover "the scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation."

Studies on income inequality and growth have sometimes found evidence confirming the Kuznets curve hypothesis, which states that with economic development, inequality first increases, then decreases. Economist Thomas Piketty challenges this notion, claiming that from 1914 to 1945 wars and "violent economic and political shocks" reduced inequality. Moreover, Piketty argues that the "magical" Kuznets curve hypothesis, with its emphasis on the balancing of economic growth in the long run, cannot account for the significant increase in economic inequality throughout the developed world since the 1970s.

The city resumed its role as the capital of Poland and the country's centre of political and economic life. Many of the historic streets, buildings, and churches were restored to their original form. In 1980, Warsaw's historic Old Town was inscribed onto UNESCO's World Heritage list.

First, if a Directive's deadline for implementation is not met, the member state cannot enforce conflicting laws, and a citizen may rely on the Directive in such an action (so called "vertical" direct effect). So, in Pubblico Ministero v Ratti because the Italian government had failed to implement a Directive 73/173/EEC on packaging and labelling solvents by the deadline, it was estopped from enforcing a conflicting national law from 1963 against Mr Ratti's solvent and varnish business. A member state could "not rely, as against individuals, on its own failure to perform the obligations which the Directive entails." Second, a citizen or company can invoke a Directive, not just in a dispute with a public authority, but in a dispute with another citizen or company. So, in CIA Security v Signalson and Securitel the Court of Justice held that a business called CIA Security could defend itself from allegations by competitors that it had not complied with a Belgian decree from 1991 about alarm systems, on the basis that it had not been notified to the Commission as a Directive required. Third, if a Directive gives expression to a "general principle" of EU law, it can be invoked between private non-state parties before its deadline for implementation. This follows from Kücükdeveci v Swedex GmbH & Co KG where the German Civil Code §622 stated that the years people worked under the age of 25 would not count towards the increasing statutory notice before dismissal. Ms Kücükdeveci worked for 10 years, from age 18 to 28, for Swedex GmbH & Co KG before her dismissal. She claimed that the law not counting her years under age 25 was unlawful age discrimination under the Employment Equality Framework Directive. The Court of Justice held that the Directive could be relied on by her because equality was also a general principle of EU law. Third, if the defendant is an emanation of the state, even if not central government, it can still be bound by Directives. In Foster v British Gas plc the Court of Justice held that Mrs Foster was entitled to bring a sex discrimination claim against her employer, British Gas plc, which made women retire at age 60 and men at 65, if (1) pursuant to a state measure, (2) it provided a public service, and (3) had special powers. This could also be true if the enterprise is privatised, as it was held with a water company that was responsible for basic water provision.

How long did Ms Kucukdeveci work for Swedex Gmbh & Co KG before she was dismissed?


The University of Chicago was created and incorporated as a coeducational, secular institution in 1890 by the American Baptist Education Society and a donation from oil magnate and philanthropist John D. Rockefeller on land donated by Marshall Field. While the Rockefeller donation provided money for academic operations and long-term endowment, it was stipulated that such money could not be used for buildings. The original physical campus was financed by donations from wealthy Chicagoans like Silas B. Cobb who provided the funds for the campus' first building, Cobb Lecture Hall, and matched Marshall Field's pledge of $100,000. Other early benefactors included businessmen Charles L. Hutchinson (trustee, treasurer and donor of Hutchinson Commons), Martin A. Ryerson (president of the board of trustees and donor of the Ryerson Physical Laboratory) Adolphus Clay Bartlett and Leon Mandel, who funded the construction of the gymnasium and assembly hall, and George C. Walker of the Walker Museum, a relative of Cobb who encouraged his inaugural donation for facilities.

Scottish Parliament:

In addition to the General Assembly Hall, the Parliament also used buildings rented from the City of Edinburgh Council. The former administrative building of Lothian Regional Council on George IV Bridge was used for the MSP's offices. Following the move to Holyrood in 2004 this building was demolished. The former Midlothian County Buildings facing Parliament Square, High Street and George IV Bridge in Edinburgh (originally built as the headquarters of the pre-1975 Midlothian County Council) housed the Parliament's visitors' centre and shop, whilst the main hall was used as the Parliament's principal committee room.

Read this: Britain gained control of French Canada and Acadia, colonies containing approximately 80,000 primarily French-speaking Roman Catholic residents. The deportation of Acadians beginning in 1755 resulted in land made available to migrants from Europe and the colonies further south. The British resettled many Acadians throughout its North American provinces, but many went to France, and some went to New Orleans, which they had expected to remain French. Some were sent to colonize places as diverse as French Guiana and the Falkland Islands; these latter efforts were unsuccessful. Others migrated to places like Saint-Domingue, and fled to New Orleans after the Haitian Revolution. The Louisiana population contributed to the founding of the modern Cajun population. (The French word "Acadien" evolved to "Cadien", then to "Cajun".)

How many French colonists weren't gained by British?

A function problem is a computational problem where a single output (of a total function) is expected for every input, but the output is more complex than that of a decision problem, that is, it isn't just yes or no. Notable examples include the traveling salesman problem and the integer factorization problem.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Is the output of a functional problem typically characterized by a simple or complex answer?


Read this: The modern trend in design is toward integration of previously separated specialties, especially among large firms. In the past, architects, interior designers, engineers, developers, construction managers, and general contractors were more likely to be entirely separate companies, even in the larger firms. Presently, a firm that is nominally an "architecture" or "construction management" firm may have experts from all related fields as employees, or to have an associated company that provides each necessary skill. Thus, each such firm may offer itself as "one-stop shopping" for a construction project, from beginning to end. This is designated as a "design build" contract where the contractor is given a performance specification and must undertake the project from design to construction, while adhering to the performance specifications.

The Rhine-Meuse Delta, the most important natural region of the Netherlands begins near Millingen aan de Rijn, close to the Dutch-German border with the division of the Rhine into Waal and Nederrijn. Since the Rhine contributes most of the water, the shorter term Rhine Delta is commonly used. However, this name is also used for the river delta where the Rhine flows into Lake Constance, so it is clearer to call the larger one Rhine-Meuse delta, or even Rhine–Meuse–Scheldt delta, as the Scheldt ends in the same delta.

What is the least important natural region of the Netherlands?

Starting in the late 1950s, American computer scientist Paul Baran developed the concept Distributed Adaptive Message Block Switching with the goal to provide a fault-tolerant, efficient routing method for telecommunication messages as part of a research program at the RAND Corporation, funded by the US Department of Defense. This concept contrasted and contradicted the theretofore established principles of pre-allocation of network bandwidth, largely fortified by the development of telecommunications in the Bell System. The new concept found little resonance among network implementers until the independent work of Donald Davies at the National Physical Laboratory (United Kingdom) (NPL) in the late 1960s. Davies is credited with coining the modern name packet switching and inspiring numerous packet switching networks in Europe in the decade following, including the incorporation of the concept in the early ARPANET in the United States.

Victoria has a written constitution enacted in 1975, but based on the 1855 colonial constitution, passed by the United Kingdom Parliament as the Victoria Constitution Act 1855, which establishes the Parliament as the state's law-making body for matters coming under state responsibility. The Victorian Constitution can be amended by the Parliament of Victoria, except for certain "entrenched" provisions that require either an absolute majority in both houses, a three-fifths majority in both houses, or the approval of the Victorian people in a referendum, depending on the provision.

Private schools in Australia may be favoured for many reasons: prestige and the social status of the 'old school tie'; better quality physical infrastructure and more facilities (e.g. playing fields, swimming pools, etc.), higher-paid teachers; and/or the belief that private schools offer a higher quality of education. Some schools offer the removal of the purported distractions of co-education; the presence of boarding facilities; or stricter discipline based on their power of expulsion, a tool not readily available to government schools. Student uniforms for Australian private schools are generally stricter and more formal than in government schools - for example, a compulsory blazer. Private schools in Australia are always more expensive than their public counterparts.[citation needed]

Steam engines are external combustion engines, where the working fluid is separate from the combustion products. Non-combustion heat sources such as solar power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In the cycle, water is heated and transforms into steam within a boiler operating at a high pressure. When expanded through pistons or turbines, mechanical work is done. The reduced-pressure steam is then condensed and pumped back into the boiler.

Free oxygen gas was almost nonexistent in Earth's atmosphere before photosynthetic archaea and bacteria evolved, probably about 3.5 billion years ago. Free oxygen first appeared in significant quantities during the Paleoproterozoic eon (between 3.0 and 2.3 billion years ago). For the first billion years, any free oxygen produced by these organisms combined with dissolved iron in the oceans to form banded iron formations. When such oxygen sinks became saturated, free oxygen began to outgas from the oceans 3–2.7 billion years ago, reaching 10% of its present level around 1.7 billion years ago.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): During which eon did free oxygen begin appearing in quantity?

An Islamist movement influenced by Salafism and the jihad in Afghanistan, as well as the Muslim Brotherhood, was the FIS or Front Islamique de Salut (the Islamic Salvation Front) in Algeria. Founded as a broad Islamist coalition in 1989 it was led by Abbassi Madani, and a charismatic Islamist young preacher, Ali Belhadj. Taking advantage of economic failure and unpopular social liberalization and secularization by the ruling leftist-nationalist FLN government, it used its preaching to advocate the establishment of a legal system following Sharia law, economic liberalization and development program, education in Arabic rather than French, and gender segregation, with women staying home to alleviate the high rate of unemployment among young Algerian men. The FIS won sweeping victories in local elections and it was going to win national elections in 1991 when voting was canceled by a military coup d'état.

Prior to European settlement, the area now constituting Victoria was inhabited by a large number of Aboriginal peoples, collectively known as the Koori. With Great Britain having claimed the entire Australian continent east of the 135th meridian east in 1788, Victoria was included in the wider colony of New South Wales. The first settlement in the area occurred in 1803 at Sullivan Bay, and much of what is now Victoria was included in the Port Phillip District in 1836, an administrative division of New South Wales. Victoria was officially created a separate colony in 1851, and achieved self-government in 1855. The Victorian gold rush in the 1850s and 1860s significantly increased both the population and wealth of the colony, and by the Federation of Australia in 1901, Melbourne had become the largest city and leading financial centre in Australasia. Melbourne also served as capital of Australia until the construction of Canberra in 1927, with the Federal Parliament meeting in Melbourne's Parliament House and all principal offices of the federal government being based in Melbourne.

The Rankine cycle and most practical steam engines have a water pump to recycle or top up the boiler water, so that they may be run continuously. Utility and industrial boilers commonly use multi-stage centrifugal pumps; however, other types are used. Another means of supplying lower-pressure boiler feed water is an injector, which uses a steam jet usually supplied from the boiler. Injectors became popular in the 1850s but are no longer widely used, except in applications such as steam locomotives.
Try to answer this question if possible (otherwise reply "unanswerable"): In what decade were injectors widely used in steam engines?


Read this: One of the first known experiments on the relationship between combustion and air was conducted by the 2nd century BCE Greek writer on mechanics, Philo of Byzantium. In his work Pneumatica, Philo observed that inverting a vessel over a burning candle and surrounding the vessel's neck with water resulted in some water rising into the neck. Philo incorrectly surmised that parts of the air in the vessel were converted into the classical element fire and thus were able to escape through pores in the glass. Many centuries later Leonardo da Vinci built on Philo's work by observing that a portion of air is consumed during combustion and respiration.

The economy of Victoria is highly diversified: service sectors including financial and property services, health, education, wholesale, retail, hospitality and manufacturing constitute the majority of employment. Victoria's total gross state product (GSP) is ranked second in Australia, although Victoria is ranked fourth in terms of GSP per capita because of its limited mining activity. Culturally, Melbourne is home to a number of museums, art galleries and theatres and is also described as the "sporting capital of Australia". The Melbourne Cricket Ground is the largest stadium in Australia, and the host of the 1956 Summer Olympics and the 2006 Commonwealth Games. The ground is also considered the "spiritual home" of Australian cricket and Australian rules football, and hosts the grand final of the Australian Football League (AFL) each year, usually drawing crowds of over 95,000 people. Victoria includes eight public universities, with the oldest, the University of Melbourne, having been founded in 1853.

Civil disobedience:

Along with giving the offender his "just deserts", achieving crime control via incapacitation and deterrence is a major goal of criminal punishment. Brownlee argues, "Bringing in deterrence at the level of justification detracts from the law’s engagement in a moral dialogue with the offender as a rational person because it focuses attention on the threat of punishment and not the moral reasons to follow this law." Leonard Hubert Hoffmann writes, "In deciding whether or not to impose punishment, the most important consideration would be whether it would do more harm than good. This means that the objector has no right not to be punished. It is a matter for the state (including the judges) to decide on utilitarian grounds whether to do so or not."

If the input size is n, the time taken can be expressed as a function of n. Since the time taken on different inputs of the same size can be different, the worst-case time complexity T(n) is defined to be the maximum time taken over all inputs of size n. If T(n) is a polynomial in n, then the algorithm is said to be a polynomial time algorithm. Cobham's thesis says that a problem can be solved with a feasible amount of resources if it admits a polynomial time algorithm.

Firstly, certain costs are difficult to avoid and are shared by everyone, such as the costs of housing, pensions, education and health care. If the state does not provide these services, then for those on lower incomes, the costs must be borrowed and often those on lower incomes are those who are worse equipped to manage their finances. Secondly, aspirational consumption describes the process of middle income earners aspiring to achieve the standards of living enjoyed by their wealthier counterparts and one method of achieving this aspiration is by taking on debt. The result leads to even greater inequality and potential economic instability.

Most of the Huguenot congregations (or individuals) in North America eventually affiliated with other Protestant denominations with more numerous members. The Huguenots adapted quickly and often married outside their immediate French communities, which led to their assimilation. Their descendants in many families continued to use French first names and surnames for their children well into the nineteenth century. Assimilated, the French made numerous contributions to United States economic life, especially as merchants and artisans in the late Colonial and early Federal periods. For example, E.I. du Pont, a former student of Lavoisier, established the Eleutherian gunpowder mills.

In some rural areas in the United Kingdom, there are dispensing physicians who are allowed to both prescribe and dispense prescription-only medicines to their patients from within their practices. The law requires that the GP practice be located in a designated rural area and that there is also a specified, minimum distance (currently 1.6 kilometres) between a patient's home and the nearest retail pharmacy. This law also exists in Austria for general physicians if the nearest pharmacy is more than 4 kilometers away, or where none is registered in the city.

Kublai's government faced financial difficulties after 1279. Wars and construction projects had drained the Mongol treasury. Efforts to raise and collect tax revenues were plagued by corruption and political scandals. Mishandled military expeditions followed the financial problems. Kublai's second invasion of Japan in 1281 failed because of an inauspicious typhoon. Kublai botched his campaigns against Annam, Champa, and Java, but won a Pyrrhic victory against Burma. The expeditions were hampered by disease, an inhospitable climate, and a tropical terrain unsuitable for the mounted warfare of the Mongols. The Tran dynasty which ruled Annam (Dai Viet) crushed and defeated the Mongols at the Battle of Bạch Đằng (1288). The Chinese region of Fujian was the original home of the Chinese Tran (Chen) clan before they migrated under Trần Kinh (陳京, Chén Jīng) to Dai Viet and whose descendants established the Trần dynasty which ruled Vietnam Đại Việt, and certain members of the clan could still speak Chinese such as when a Yuan dynasty envoy had a meeting with the Chinese-speaking Trần prince Trần Quốc Tuấn (later King Trần Hưng Đạo) in 1282. Professor Liam Kelley noted that people from Song dynasty China like Zhao Zhong and Xu Zongdao fled to Tran dynasty ruled Vietnam after the Mongol invasion of the Song and they helped the Tran fight against the Mongol invasion. The Tran dynasty originated from the Fujian region of China as did the Daoist cleric Xu Zongdao who recorded the Mongol invasion and referred to them as "Northern bandits". Annam, Burma, and Champa recognized Mongol hegemony and established tributary relations with the Yuan dynasty.

These attacks resonated with conservative Muslims and the problem did not go away with Saddam's defeat either, since American troops remained stationed in the kingdom, and a de facto cooperation with the Palestinian-Israeli peace process developed. Saudi Arabia attempted to compensate for its loss of prestige among these groups by repressing those domestic Islamists who attacked it (bin Laden being a prime example), and increasing aid to Islamic groups (Islamist madrassas around the world and even aiding some violent Islamist groups) that did not, but its pre-war influence on behalf of moderation was greatly reduced. One result of this was a campaign of attacks on government officials and tourists in Egypt, a bloody civil war in Algeria and Osama bin Laden's terror attacks climaxing in the 9/11 attack.

Who masterminded many terror attacks?


Homes from the early 20th century line this boulevard in the heart of the historic Alta Vista Tract. The section of Huntington Boulevard between First Street on the west to Cedar Avenue on the east is the home to many large, stately homes. The original development of this area began circa 1910, on 190 acres of what had been an alfalfa field. The Alta Vista Tract, as the land would become known, was mapped by William Stranahan for the Pacific Improvement Corporation, and was officially platted in 1911. The tract's boundaries were Balch Avenue on the south, Cedar Avenue on the east, the rear property line of Platt Avenue (east of Sixth Street) and Platt Avenue (west of Sixth Street) on the north, and First Street on the west. The subdivision was annexed to the City in January 1912, in an election that was the first in which women voted in the community. At the time of its admission to the City, the Alta Vista Tract was uninhabited but landscaped, although the trees had to be watered by tank wagon. In 1914 developers Billings & Meyering acquired the tract, completed street development, provided the last of the necessary municipal improvements including water service, and began marketing the property with fervor. A mere half decade later the tract had 267 homes. This rapid development was no doubt hastened by the Fresno Traction Company right-of-way along Huntington Boulevard, which provided streetcar connections between downtown and the County Hospital.

Iqbal expressed fears that not only would secularism and secular nationalism weaken the spiritual foundations of Islam and Muslim society, but that India's Hindu-majority population would crowd out Muslim heritage, culture and political influence. In his travels to Egypt, Afghanistan, Palestine and Syria, he promoted ideas of greater Islamic political co-operation and unity, calling for the shedding of nationalist differences. Sir Muhammad Iqbal was elected president of the Muslim League in 1930 at its session in Allahabad as well as for the session in Lahore in 1932. In his Allahabad Address on 29 December 1930, Iqbal outlined a vision of an independent state for Muslim-majority provinces in northwestern India. This address later inspired the Pakistan movement.

 When Iqbal promoted ideas of greater Islamic political unity, what did he discourage ending?


Renewed religious warfare in the 1620s caused the political and military privileges of the Huguenots to be abolished following their defeat. They retained the religious provisions of the Edict of Nantes until the rule of Louis XIV, who progressively increased persecution of them until he issued the Edict of Fontainebleau (1685), which abolished all legal recognition of Protestantism in France, and forced the Huguenots to convert. While nearly three-quarters eventually were killed  or submitted, roughly 500,000 Huguenots had fled France by the early 18th century[citation needed].

The mouth of the Rhine into Lake Constance forms an inland delta. The delta is delimited in the West by the Alter Rhein ("Old Rhine") and in the East by a modern canalized section. Most of the delta is a nature reserve and bird sanctuary. It includes the Austrian towns of Gaißau, Höchst and Fußach. The natural Rhine originally branched into at least two arms and formed small islands by precipitating sediments. In the local Alemannic dialect, the singular is pronounced "Isel" and this is also the local pronunciation of Esel ("Donkey"). Many local fields have an official name containing this element.

What is one of the mammal animals that lives in the nature reserve and bird sanctuary?


Kublai Khan promoted commercial, scientific, and cultural growth. He supported the merchants of the Silk Road trade network by protecting the Mongol postal system, constructing infrastructure, providing loans that financed trade caravans, and encouraging the circulation of paper banknotes (鈔, Chao). Pax Mongolica, Mongol peace, enabled the spread of technologies, commodities, and culture between China and the West. Kublai expanded the Grand Canal from southern China to Daidu in the north. Mongol rule was cosmopolitan under Kublai Khan. He welcomed foreign visitors to his court, such as the Venetian merchant Marco Polo, who wrote the most influential European account of Yuan China. Marco Polo's travels would later inspire many others like Christopher Columbus to chart a passage to the Far East in search of its legendary wealth.

Johnson's expedition was better organized than Shirley's, which was noticed by New France's governor, the Marquis de Vaudreuil. He had primarily been concerned about the extended supply line to the forts on the Ohio, and had sent Baron Dieskau to lead the defenses at Frontenac against Shirley's expected attack. When Johnson was seen as the larger threat, Vaudreuil sent Dieskau to Fort St. Frédéric to meet that threat. Dieskau planned to attack the British encampment at Fort Edward at the upper end of navigation on the Hudson River, but Johnson had strongly fortified it, and Dieskau's Indian support was reluctant to attack. The two forces finally met in the bloody Battle of Lake George between Fort Edward and Fort William Henry. The battle ended inconclusively, with both sides withdrawing from the field. Johnson's advance stopped at Fort William Henry, and the French withdrew to Ticonderoga Point, where they began the construction of Fort Carillon (later renamed Fort Ticonderoga after British capture in 1759).

Read this: Several commemorative events take place every year. Gatherings of thousands of people on the banks of the Vistula on Midsummer’s Night for a festival called Wianki (Polish for Wreaths) have become a tradition and a yearly event in the programme of cultural events in Warsaw. The festival traces its roots to a peaceful pagan ritual where maidens would float their wreaths of herbs on the water to predict when they would be married, and to whom. By the 19th century this tradition had become a festive event, and it continues today. The city council organize concerts and other events. Each Midsummer’s Eve, apart from the official floating of wreaths, jumping over fires, looking for the fern flower, there are musical performances, dignitaries' speeches, fairs and fireworks by the river bank.

Jacksonville has suffered less damage from hurricanes than most other east coast cities, although the threat does exist for a direct hit by a major hurricane. The city has only received one direct hit from a hurricane since 1871; however, Jacksonville has experienced hurricane or near-hurricane conditions more than a dozen times due to storms crossing the state from the Gulf of Mexico to the Atlantic Ocean, or passing to the north or south in the Atlantic and brushing past the area. The strongest effect on Jacksonville was from Hurricane Dora in 1964, the only recorded storm to hit the First Coast with sustained hurricane-force winds. The eye crossed St. Augustine with winds that had just barely diminished to 110 mph (180 km/h), making it a strong Category 2 on the Saffir-Simpson Scale. Jacksonville also suffered damage from 2008's Tropical Storm Fay which crisscrossed the state, bringing parts of Jacksonville under darkness for four days. Similarly, four years prior to this, Jacksonville was inundated by Hurricane Frances and Hurricane Jeanne, which made landfall south of the area. These tropical cyclones were the costliest indirect hits to Jacksonville. Hurricane Floyd in 1999 caused damage mainly to Jacksonville Beach. During Floyd, the Jacksonville Beach pier was severely damaged, and later demolished. The rebuilt pier was later damaged by Fay, but not destroyed. Tropical Storm Bonnie would cause minor damage in 2004, spawning a minor tornado in the process. On May 28, 2012, Jacksonville was hit by Tropical Storm Beryl, packing winds up to 70 miles per hour (113 km/h) which made landfall near Jacksonville Beach.

AppleTalk was a proprietary suite of networking protocols developed by Apple Inc. in 1985 for Apple Macintosh computers. It was the primary protocol used by Apple devices through the 1980s and 90s. AppleTalk included features that allowed local area networks to be established ad hoc without the requirement for a centralized router or server. The AppleTalk system automatically assigned addresses, updated the distributed namespace, and configured any required inter-network routing. It was a plug-n-play system.

Why was Appletalk considered plug-n-play?


There have been debates as to whether civil disobedience must necessarily be non-violent. Black's Law Dictionary includes non-violence in its definition of civil disobedience. Christian Bay's encyclopedia article states that civil disobedience requires "carefully chosen and legitimate means," but holds that they do not have to be non-violent. It has been argued that, while both civil disobedience and civil rebellion are justified by appeal to constitutional defects, rebellion is much more destructive; therefore, the defects justifying rebellion must be much more serious than those justifying disobedience, and if one cannot justify civil rebellion, then one cannot justify a civil disobedients' use of force and violence and refusal to submit to arrest. Civil disobedients' refraining from violence is also said to help preserve society's tolerance of civil disobedience.

Montpellier was among the most important of the 66 "villes de sûreté" that the Edict of 1598 granted to the Huguenots. The city's political institutions and the university were all handed over to the Huguenots. Tension with Paris led to a siege by the royal army in 1622. Peace terms called for the dismantling of the city's fortifications. A royal citadel was built and the university and consulate were taken over by the Catholic party. Even before the Edict of Alès (1629), Protestant rule was dead and the ville de sûreté was no more.[citation needed]

According to economists David Castells-Quintana and Vicente Royuela, increasing inequality harms economic growth. High and persistent unemployment, in which inequality increases, has a negative effect on subsequent long-run economic growth. Unemployment can harm growth not only because it is a waste of resources, but also because it generates redistributive pressures and subsequent distortions, drives people to poverty, constrains liquidity limiting labor mobility, and erodes self-esteem promoting social dislocation, unrest and conflict. Policies aiming at controlling unemployment and in particular at reducing its inequality-associated effects support economic growth.

The Cestida ("belt animals") are ribbon-shaped planktonic animals, with the mouth and aboral organ aligned in the middle of opposite edges of the ribbon. There is a pair of comb-rows along each aboral edge, and tentilla emerging from a groove all along the oral edge, which stream back across most of the wing-like body surface. Cestids can swim by undulating their bodies as well as by the beating of their comb-rows. There are two known species, with worldwide distribution in warm, and warm-temperate waters: Cestum veneris ("Venus' girdle") is among the largest ctenophores – up to 1.5 meters (4.9 ft) long, and can undulate slowly or quite rapidly. Velamen parallelum, which is typically less than 20 centimeters (0.66 ft) long, can move much faster in what has been described as a "darting motion".

Read this: Since the IPCC does not carry out its own research, it operates on the basis of scientific papers and independently documented results from other scientific bodies, and its schedule for producing reports requires a deadline for submissions prior to the report's final release. In principle, this means that any significant new evidence or events that change our understanding of climate science between this deadline and publication of an IPCC report cannot be included. In an area of science where our scientific understanding is rapidly changing, this has been raised as a serious shortcoming in a body which is widely regarded as the ultimate authority on the science. However, there has generally been a steady evolution of key findings and levels of scientific confidence from one assessment report to the next.[citation needed]

Read this: The shape of the Rhine delta is determined by two bifurcations: first, at Millingen aan de Rijn, the Rhine splits into Waal and Pannerdens Kanaal, which changes its name to Nederrijn at Angeren, and second near Arnhem, the IJssel branches off from the Nederrijn. This creates three main flows, two of which change names rather often. The largest and southern main branch begins as Waal and continues as Boven Merwede ("Upper Merwede"), Beneden Merwede ("Lower Merwede"), Noord River ("North River"), Nieuwe Maas ("New Meuse"), Het Scheur ("the Rip") and Nieuwe Waterweg ("New Waterway"). The middle flow begins as Nederrijn, then changes into Lek, then joins the Noord, thereby forming Nieuwe Maas. The northern flow keeps the name IJssel until it flows into Lake IJsselmeer. Three more flows carry significant amounts of water: the Nieuwe Merwede ("New Merwede"), which branches off from the southern branch where it changes from Boven to Beneden Merwede; the Oude Maas ("Old Meuse"), which branches off from the southern branch where it changes from Beneden Merwede into Noord, and Dordtse Kil, which branches off from Oude Maas.

This is the most common method of construction procurement and is well established and recognized. In this arrangement, the architect or engineer acts as the project coordinator. His or her role is to design the works, prepare the specifications and produce construction drawings, administer the contract, tender the works, and manage the works from inception to completion. There are direct contractual links between the architect's client and the main contractor. Any subcontractor has a direct contractual relationship with the main contractor. The procedure continues until the building is ready to occupy.

Read this: Civil disobedience is usually defined as pertaining to a citizen's relation to the state and its laws, as distinguished from a constitutional impasse in which two public agencies, especially two equally sovereign branches of government, conflict. For instance, if the head of government of a country were to refuse to enforce a decision of that country's highest court, it would not be civil disobedience, since the head of government would be acting in her or his capacity as public official rather than private citizen.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): A constitutional impasse pertains to how a citizen relates to the state and what?

The IPCC Fourth Assessment Report (AR4) published in 2007 featured a graph showing 12 proxy based temperature reconstructions, including the three highlighted in the 2001 Third Assessment Report (TAR); Mann, Bradley & Hughes 1999 as before, Jones et al. 1998 and Briffa 2000 had both been calibrated by newer studies. In addition, analysis of the Medieval Warm Period cited reconstructions by Crowley & Lowery 2000 (as cited in the TAR) and Osborn & Briffa 2006. Ten of these 14 reconstructions covered 1,000 years or longer. Most reconstructions shared some data series, particularly tree ring data, but newer reconstructions used additional data and covered a wider area, using a variety of statistical methods. The section discussed the divergence problem affecting certain tree ring data.

What problem did some tree ring data have?

The principles of imperialism are often generalizable to the policies and practices of the British Empire "during the last generation, and proceeds rather by diagnosis than by historical description". British imperialism often used the concept of Terra nullius (Latin expression which stems from Roman law meaning 'empty land'). The country of Australia serves as a case study in relation to British settlement and colonial rule of the continent in the eighteenth century, as it was premised on terra nullius, and its settlers considered it unused by its sparse Aboriginal inhabitants.

 What were the non-native inhabitants of Australia called?


The notion "force" keeps its meaning in quantum mechanics, though one is now dealing with operators instead of classical variables and though the physics is now described by the Schrödinger equation instead of Newtonian equations. This has the consequence that the results of a measurement are now sometimes "quantized", i.e. they appear in discrete portions. This is, of course, difficult to imagine in the context of "forces". However, the potentials V(x,y,z) or fields, from which the forces generally can be derived, are treated similar to classical position variables, i.e., .

Guo Shoujing applied mathematics to the construction of calendars. He was one of the first mathematicians in China to work on spherical trigonometry. Gou derived a cubic interpolation formula for his astronomical calculations. His calendar, the Shoushi Li (授時暦) or Calendar for Fixing the Seasons, was disseminated in 1281 as the official calendar of the Yuan dynasty. The calendar may have been influenced solely by the work of Song dynasty astronomer Shen Kuo or possibly by the work of Arab astronomers. There are no explicit signs of Muslim influences in the Shoushi calendar, but Mongol rulers were known to be interested in Muslim calendars. Mathematical knowledge from the Middle East was introduced to China under the Mongols, and Muslim astronomers brought Arabic numerals to China in the 13th century.

When did Gou's calendar become the official calendar of the Yuan?


The path of violence and military struggle was then taken up by the Egyptian Islamic Jihad organization responsible for the assassination of Anwar Sadat in 1981. Unlike earlier anti-colonial movements the extremist group directed its attacks against what it believed were "apostate" leaders of Muslim states, leaders who held secular leanings or who had introduced or promoted Western/foreign ideas and practices into Islamic societies. Its views were outlined in a pamphlet written by Muhammad Abd al-Salaam Farag, in which he states:

In the late 17th century, Robert Boyle proved that air is necessary for combustion. English chemist John Mayow (1641–1679) refined this work by showing that fire requires only a part of air that he called spiritus nitroaereus or just nitroaereus. In one experiment he found that placing either a mouse or a lit candle in a closed container over water caused the water to rise and replace one-fourteenth of the air's volume before extinguishing the subjects. From this he surmised that nitroaereus is consumed in both respiration and combustion.

What was the profession of John Boyle?


Many Han Chinese and Khitan defected to the Mongols to fight against the Jin. Two Han Chinese leaders, Shi Tianze, Liu Heima (劉黑馬, Liu Ni), and the Khitan Xiao Zhala (蕭札剌) defected and commanded the 3 Tumens in the Mongol army. Liu Heima and Shi Tianze served Ogödei Khan. Liu Heima and Shi Tianxiang led armies against Western Xia for the Mongols. There were 4 Han Tumens and 3 Khitan Tumens, with each Tumen consisting of 10,000 troops. The three Khitan Generals Shimobeidier (石抹孛迭兒), Tabuyir (塔不已兒) and Xiaozhacizhizizhongxi (蕭札刺之子重喜) commanded the three Khitan Tumens and the four Han Generals Zhang Rou, Yan Shi, Shi Tianze, and Liu Heima commanded the four Han tumens under Ogödei Khan.

The Beroida, also known as Nuda, have no feeding appendages, but their large pharynx, just inside the large mouth and filling most of the saclike body, bears "macrocilia" at the oral end. These fused bundles of several thousand large cilia are able to "bite" off pieces of prey that are too large to swallow whole – almost always other ctenophores. In front of the field of macrocilia, on the mouth "lips" in some species of Beroe, is a pair of narrow strips of adhesive epithelial cells on the stomach wall that "zip" the mouth shut when the animal is not feeding, by forming intercellular connections with the opposite adhesive strip. This tight closure streamlines the front of the animal when it is pursuing prey.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What are epithelial cells able do do if prey is too large to swallow?


Packet switching contrasts with another principal networking paradigm, circuit switching, a method which pre-allocates dedicated network bandwidth specifically for each communication session, each having a constant bit rate and latency between nodes. In cases of billable services, such as cellular communication services, circuit switching is characterized by a fee per unit of connection time, even when no data is transferred, while packet switching may be characterized by a fee per unit of information transmitted, such as characters, packets, or messages.
Try to answer this question if possible (otherwise reply "unanswerable"): How is circuit switching allocated


The concept of inertia can be further generalized to explain the tendency of objects to continue in many different forms of constant motion, even those that are not strictly constant velocity. The rotational inertia of planet Earth is what fixes the constancy of the length of a day and the length of a year. Albert Einstein extended the principle of inertia further when he explained that reference frames subject to constant acceleration, such as those free-falling toward a gravitating object, were physically equivalent to inertial reference frames. This is why, for example, astronauts experience weightlessness when in free-fall orbit around the Earth, and why Newton's Laws of Motion are more easily discernible in such environments. If an astronaut places an object with mass in mid-air next to himself, it will remain stationary with respect to the astronaut due to its inertia. This is the same thing that would occur if the astronaut and the object were in intergalactic space with no net force of gravity acting on their shared reference frame. This principle of equivalence was one of the foundational underpinnings for the development of the general theory of relativity.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What concept explains why objects continue in constant motion?


Read this: It was only the orbit of the planet Mercury that Newton's Law of Gravitation seemed not to fully explain. Some astrophysicists predicted the existence of another planet (Vulcan) that would explain the discrepancies; however, despite some early indications, no such planet could be found. When Albert Einstein formulated his theory of general relativity (GR) he turned his attention to the problem of Mercury's orbit and found that his theory added a correction, which could account for the discrepancy. This was the first time that Newton's Theory of Gravity had been shown to be less correct than an alternative.

Read this: The USSR's invasion of Afghanistan was only one sign of insecurity in the region, also marked by increased American weapons sales, technology, and outright military presence. Saudi Arabia and Iran became increasingly dependent on American security assurances to manage both external and internal threats, including increased military competition between them over increased oil revenues. Both states were competing for preeminence in the Persian Gulf and using increased revenues to fund expanded militaries. By 1979, Saudi arms purchases from the US exceeded five times Israel's. Another motive for the large scale purchase of arms from the US by Saudi Arabia was the failure of the Shah during January 1979 to maintain control of Iran, a non-Arabic but largely Shiite Muslim nation, which fell to a theocratic Islamist government under the Ayatollah Ruhollah Khomeini in the wake of the 1979 Iranian Revolution. Saudi Arabia, on the other hand, is an Arab, largely Sunni Muslim nation headed by a near absolutist monarchy. In the wake of the Iranian revolution the Saudis were forced to deal with the prospect of internal destabilization via the radicalism of Islamism, a reality which would quickly be revealed in the seizure of the Grand Mosque in Mecca by Wahhabi extremists during November 1979 and a Shiite revolt in the oil rich Al-Hasa region of Saudi Arabia in December of the same year. In November 2010, Wikileaks leaked confidential diplomatic cables pertaining to the United States and its allies which revealed that the late Saudi King Abdullah urged the United States to attack Iran in order to destroy its potential nuclear weapons program, describing Iran as "a snake whose head should be cut off without any procrastination."

Read this: Firstly, certain costs are difficult to avoid and are shared by everyone, such as the costs of housing, pensions, education and health care. If the state does not provide these services, then for those on lower incomes, the costs must be borrowed and often those on lower incomes are those who are worse equipped to manage their finances. Secondly, aspirational consumption describes the process of middle income earners aspiring to achieve the standards of living enjoyed by their wealthier counterparts and one method of achieving this aspiration is by taking on debt. The result leads to even greater inequality and potential economic instability.

The flow of cold, gray mountain water continues for some distance into the lake. The cold water flows near the surface and at first doesn't mix with the warmer, green waters of Upper Lake. But then, at the so-called Rheinbrech, the Rhine water abruptly falls into the depths because of the greater density of cold water. The flow reappears on the surface at the northern (German) shore of the lake, off the island of Lindau. The water then follows the northern shore until Hagnau am Bodensee. A small fraction of the flow is diverted off the island of Mainau into Lake Überlingen. Most of the water flows via the Constance hopper into the Rheinrinne ("Rhine Gutter") and Seerhein. Depending on the water level, this flow of the Rhine water is clearly visible along the entire length of the lake.

Answer this question, if possible (if impossible, reply "unanswerable"): What does the flow of the Rhine being visible depend on?


Steam engine:

One of the principal advantages the Rankine cycle holds over others is that during the compression stage relatively little work is required to drive the pump, the working fluid being in its liquid phase at this point. By condensing the fluid, the work required by the pump consumes only 1% to 3% of the turbine power and contributes to a much higher efficiency for a real cycle. The benefit of this is lost somewhat due to the lower heat addition temperature. Gas turbines, for instance, have turbine entry temperatures approaching 1500 °C. Nonetheless, the efficiencies of actual large steam cycles and large modern gas turbines are fairly well matched.[citation needed]

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What is the approximate turbine entry temperature of a gas turbine?


Read this: Private schools generally prefer to be called independent schools, because of their freedom to operate outside of government and local government control. Some of these are also known as public schools. Preparatory schools in the UK prepare pupils aged up to 13 years old to enter public schools. The name "public school" is based on the fact that the schools were open to pupils from anywhere, and not merely to those from a certain locality, and of any religion or occupation. According to The Good Schools Guide approximately 9 per cent of children being educated in the UK are doing so at fee-paying schools at GSCE level and 13 per cent at A-level.[citation needed] Many independent schools are single-sex (though this is becoming less common). Fees range from under £3,000 to £21,000 and above per year for day pupils, rising to £27,000+ per year for boarders. For details in Scotland, see "Meeting the Cost".
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Who do preparatory schools in Scotland prepare to enter public schools?


The Harvard University Library System is centered in Widener Library in Harvard Yard and comprises nearly 80 individual libraries holding over 18 million volumes. According to the American Library Association, this makes it the largest academic library in the United States, and one of the largest in the world. Cabot Science Library, Lamont Library, and Widener Library are three of the most popular libraries for undergraduates to use, with easy access and central locations. There are rare books, manuscripts and other special collections throughout Harvard's libraries; Houghton Library, the Arthur and Elizabeth Schlesinger Library on the History of Women in America, and the Harvard University Archives consist principally of rare and unique materials. America's oldest collection of maps, gazetteers, and atlases both old and new is stored in Pusey Library and open to the public. The largest collection of East-Asian language material outside of East Asia is held in the Harvard-Yenching Library.

Answer this question, if possible (if impossible, reply "unanswerable"): What is the size of the Lamont Library that gives it a unique distinction?


Land-based steam engines could exhaust much of their steam, as feed water was usually readily available. Prior to and during World War I, the expansion engine dominated marine applications where high vessel speed was not essential. It was however superseded by the British invention steam turbine where speed was required, for instance in warships, such as the dreadnought battleships, and ocean liners. HMS Dreadnought of 1905 was the first major warship to replace the proven technology of the reciprocating engine with the then-novel steam turbine.[citation needed]

Packet switching:

Starting in 1965, Donald Davies at the National Physical Laboratory, UK, independently developed the same message routing methodology as developed by Baran. He called it packet switching, a more accessible name than Baran's, and proposed to build a nationwide network in the UK. He gave a talk on the proposal in 1966, after which a person from the Ministry of Defence (MoD) told him about Baran's work. A member of Davies' team (Roger Scantlebury) met Lawrence Roberts at the 1967 ACM Symposium on Operating System Principles and suggested it for use in the ARPANET.

Read this: Many major classes of organic molecules in living organisms, such as proteins, nucleic acids, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that are constituents of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as it is a part of water, the major constituent of lifeforms. Oxygen is used in cellular respiration and released by photosynthesis, which uses the energy of sunlight to produce oxygen from water. It is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone (O
3), strongly absorbs UVB radiation and consequently the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation, but is a pollutant near the surface where it is a by-product of smog. At even higher low earth orbit altitudes, sufficient atomic oxygen is present to cause erosion for spacecraft.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What absorbs UBV rays?

Read this: The Daily Mail newspaper reported in 2012 that the UK government's benefits agency was checking claimants' "Sky TV bills to establish if a woman in receipt of benefits as a single mother is wrongly claiming to be living alone" – as, it claimed, subscription to sports channels would betray a man's presence in the household. In December, the UK’s parliament heard a claim that a subscription to BSkyB was ‘often damaging’, along with alcohol, tobacco and gambling. Conservative MP Alec Shelbrooke was proposing the payments of benefits and tax credits on a "Welfare Cash Card", in the style of the Supplemental Nutrition Assistance Program, that could be used to buy only "essentials".
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What did the benefits agency think sports channels on a TV bill meant?


Most of the Rhine's current course was not under the ice during the last Ice Age; although, its source must still have been a glacier. A tundra, with Ice Age flora and fauna, stretched across middle Europe, from Asia to the Atlantic Ocean. Such was the case during the Last Glacial Maximum, ca. 22,000–14,000 yr BP, when ice-sheets covered Scandinavia, the Baltics, Scotland and the Alps, but left the space between as open tundra. The loess or wind-blown dust over that tundra, settled in and around the Rhine Valley, contributing to its current agricultural usefulness.

Answer this question, if possible (if impossible, reply "unanswerable"): What stretched across middle Europe in the last ice age?


According to International Monetary Fund economists, inequality in wealth and income is negatively correlated with the duration of economic growth spells (not the rate of growth). High levels of inequality prevent not just economic prosperity, but also the quality of a country's institutions and high levels of education. According to IMF staff economists, "if the income share of the top 20 percent (the rich) increases, then GDP growth actually declines over the medium term, suggesting that the benefits do not trickle down. In contrast, an increase in the income share of the bottom 20 percent (the poor) is associated with higher GDP growth. The poor and the middle class matter the most for growth via a number of interrelated economic, social, and political channels."
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Who matters the least for economic growth?


Steam engine:

Trevithick continued his own experiments using a trio of locomotives, concluding with the Catch Me Who Can in 1808. Only four years later, the successful twin-cylinder locomotive Salamanca by Matthew Murray was used by the edge railed rack and pinion Middleton Railway. In 1825 George Stephenson built the Locomotion for the Stockton and Darlington Railway. This was the first public steam railway in the world and then in 1829, he built The Rocket which was entered in and won the Rainhill Trials. The Liverpool and Manchester Railway opened in 1830 making exclusive use of steam power for both passenger and freight trains.
