Read this: Microorganisms or toxins that successfully enter an organism encounter the cells and mechanisms of the innate immune system. The innate response is usually triggered when microbes are identified by pattern recognition receptors, which recognize components that are conserved among broad groups of microorganisms, or when damaged, injured or stressed cells send out alarm signals, many of which (but not all) are recognized by the same receptors as those that recognize pathogens. Innate immune defenses are non-specific, meaning these systems respond to pathogens in a generic way. This system does not confer long-lasting immunity against a pathogen. The innate immune system is the dominant system of host defense in most organisms.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What system gives an organism long lasting immunity against a pathogen?


Packet switching:

Packet mode communication may be implemented with or without intermediate forwarding nodes (packet switches or routers). Packets are normally forwarded by intermediate network nodes asynchronously using first-in, first-out buffering, but may be forwarded according to some scheduling discipline for fair queuing, traffic shaping, or for differentiated or guaranteed quality of service, such as weighted fair queuing or leaky bucket. In case of a shared physical medium (such as radio or 10BASE5), the packets may be delivered according to a multiple access scheme.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Packets can be delivered via what route?


Read this: During 2003–04, the gross value of Victorian agricultural production increased by 17% to $8.7 billion. This represented 24% of national agricultural production total gross value. As of 2004, an estimated 32,463 farms occupied around 136,000 square kilometres (52,500 sq mi) of Victorian land. This comprises more than 60% of the state's total land surface. Victorian farms range from small horticultural outfits to large-scale livestock and grain productions. A quarter of farmland is used to grow consumable crops.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): How much land do farms use in Victoria?


Read this: Islamists have asked the question, "If Islam is a way of life, how can we say that those who want to live by its principles in legal, social, political, economic, and political spheres of life are not Muslims, but Islamists and believe in Islamism, not [just] Islam?" Similarly, a writer for the International Crisis Group maintains that "the conception of 'political Islam'" is a creation of Americans to explain the Iranian Islamic Revolution and apolitical Islam was a historical fluke of the "short-lived era of the heyday of secular Arab nationalism between 1945 and 1970", and it is quietist/non-political Islam, not Islamism, that requires explanation.

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).

James Hutton published a 2 volume version of his theories in what year?


Immunology is a science that examines the structure and function of the immune system. It originates from medicine and early studies on the causes of immunity to disease. The earliest known reference to immunity was during the plague of Athens in 430 BC. Thucydides noted that people who had recovered from a previous bout of the disease could nurse the sick without contracting the illness a second time. In the 18th century, Pierre-Louis Moreau de Maupertuis made experiments with scorpion venom and observed that certain dogs and mice were immune to this venom. This and other observations of acquired immunity were later exploited by Louis Pasteur in his development of vaccination and his proposed germ theory of disease. Pasteur's theory was in direct opposition to contemporary theories of disease, such as the miasma theory. It was not until Robert Koch's 1891 proofs, for which he was awarded a Nobel Prize in 1905, that microorganisms were confirmed as the cause of infectious disease. Viruses were confirmed as human pathogens in 1901, with the discovery of the yellow fever virus by Walter Reed.

Bolshevik leaders had effectively reestablished a polity with roughly the same extent as that empire by 1921, however with an internationalist ideology: Lenin in particular asserted the right to limited self-determination for national minorities within the new territory. Beginning in 1923, the policy of "Indigenization" [korenizatsiia] was intended to support non-Russians develop their national cultures within a socialist framework. Never formally revoked, it stopped being implemented after 1932. After World War II, the Soviet Union installed socialist regimes modeled on those it had installed in 1919–20 in the old Tsarist Empire in areas its forces occupied in Eastern Europe. The Soviet Union and the People’s Republic of China supported post–World War II communist movements in foreign nations and colonies to advance their own interests, but were not always successful.

When was the Russian Policy "Indigenization" defunded?

Hamas has continued to be a major player in Palestine. From 2000 to 2007 it killed 542 people in 140 suicide bombing or "martyrdom operations". In the January 2006 legislative election—its first foray into the political process—it won the majority of the seats, and in 2007 it drove the PLO out of Gaza. Hamas has been praised by Muslims for driving Israel out of the Gaza Strip, but criticized for failure to achieve its demands in the 2008-9 and 2014 Gaza Wars despite heavy destruction and significant loss of life.

 When did Hamas keep the PLO in Gaza?

Geologists use a number of field, laboratory, and numerical modeling methods to decipher Earth history and understand the processes that occur on and inside the Earth. In typical geological investigations, geologists use primary information related to petrology (the study of rocks), stratigraphy (the study of sedimentary layers), and structural geology (the study of positions of rock units and their deformation). In many cases, geologists also study modern soils, rivers, landscapes, and glaciers; investigate past and current life and biogeochemical pathways, and use geophysical methods to investigate the subsurface.

The graph isomorphism problem is the computational problem of determining whether two finite graphs are isomorphic. An important unsolved problem in complexity theory is whether the graph isomorphism problem is in P, NP-complete, or NP-intermediate. The answer is not known, but it is believed that the problem is at least not NP-complete. If graph isomorphism is NP-complete, the polynomial time hierarchy collapses to its second level. Since it is widely believed that the polynomial hierarchy does not collapse to any finite level, it is believed that graph isomorphism is not NP-complete. The best algorithm for this problem, due to Laszlo Babai and Eugene Luks has run time 2O(√(n log(n))) for graphs with n vertices.

Immune system:

Newborn infants have no prior exposure to microbes and are particularly vulnerable to infection. Several layers of passive protection are provided by the mother. During pregnancy, a particular type of antibody, called IgG, is transported from mother to baby directly across the placenta, so human babies have high levels of antibodies even at birth, with the same range of antigen specificities as their mother. Breast milk or colostrum also contains antibodies that are transferred to the gut of the infant and protect against bacterial infections until the newborn can synthesize its own antibodies. This is passive immunity because the fetus does not actually make any memory cells or antibodies—it only borrows them. This passive immunity is usually short-term, lasting from a few days up to several months. In medicine, protective passive immunity can also be transferred artificially from one individual to another via antibody-rich serum.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What people are least vulnerable to infection?


All of the forces in the universe are based on four fundamental interactions. The strong and weak forces are nuclear forces that act only at very short distances, and are responsible for the interactions between subatomic particles, including nucleons and compound nuclei. The electromagnetic force acts between electric charges, and the gravitational force acts between masses. All other forces in nature derive from these four fundamental interactions. For example, friction is a manifestation of the electromagnetic force acting between the atoms of two surfaces, and the Pauli exclusion principle, which does not permit atoms to pass through each other. Similarly, the forces in springs, modeled by Hooke's law, are the result of electromagnetic forces and the Exclusion Principle acting together to return an object to its equilibrium position. Centrifugal forces are acceleration forces that arise simply from the acceleration of rotating frames of reference.:12-11:359

Imperialism and colonialism both dictate the political and economic advantage over a land and the indigenous populations they control, yet scholars sometimes find it difficult to illustrate the difference between the two. Although imperialism and colonialism focus on the suppression of an other, if colonialism refers to the process of a country taking physical control of another, imperialism refers to the political and monetary dominance, either formally or informally. Colonialism is seen to be the architect deciding how to start dominating areas and then imperialism can be seen as creating the idea behind conquest cooperating with colonialism. Colonialism is when the imperial nation begins a conquest over an area and then eventually is able to rule over the areas the previous nation had controlled. Colonialism's core meaning is the exploitation of the valuable assets and supplies of the nation that was conquered and the conquering nation then gaining the benefits from the spoils of the war. The meaning of imperialism is to create an empire, by conquering the other state's lands and therefore increasing its own dominance. Colonialism is the builder and preserver of the colonial possessions in an area by a population coming from a foreign region. Colonialism can completely change the existing social structure, physical structure and economics of an area; it is not unusual that the characteristics of the conquering peoples are inherited by the conquered indigenous populations.

In Berlin, the Huguenots created two new neighbourhoods: Dorotheenstadt and Friedrichstadt. By 1700, one-fifth of the city's population was French speaking. The Berlin Huguenots preserved the French language in their church services for nearly a century. They ultimately decided to switch to German in protest against the occupation of Prussia by Napoleon in 1806-07. Many of their descendents rose to positions of prominence. Several congregations were founded, such as those of Fredericia (Denmark), Berlin, Stockholm, Hamburg, Frankfurt, Helsinki, and Emden.

Read this: Despite the high position given to Muslims, some policies of the Yuan Emperors severely discriminated against them, restricting Halal slaughter and other Islamic practices like circumcision, as well as Kosher butchering for Jews, forcing them to eat food the Mongol way. Toward the end, corruption and the persecution became so severe that Muslim generals joined Han Chinese in rebelling against the Mongols. The Ming founder Zhu Yuanzhang had Muslim generals like Lan Yu who rebelled against the Mongols and defeated them in combat. Some Muslim communities had a Chinese surname which meant "barracks" and could also mean "thanks". Many Hui Muslims claim this is because that they played an important role in overthrowing the Mongols and it was given in thanks by the Han Chinese for assisting them. During the war fighting the Mongols, among the Ming Emperor Zhu Yuanzhang's armies was the Hui Muslim Feng Sheng. The Muslims in the semu class also revolted against the Yuan dynasty in the Ispah Rebellion but the rebellion was crushed and the Muslims were massacred by the Yuan loyalist commander Chen Youding.

Planetary geologists have measured different abundances of oxygen isotopes in samples from the Earth, the Moon, Mars, and meteorites, but were long unable to obtain reference values for the isotope ratios in the Sun, believed to be the same as those of the primordial solar nebula. Analysis of a silicon wafer exposed to the solar wind in space and returned by the crashed Genesis spacecraft has shown that the Sun has a higher proportion of oxygen-16 than does the Earth. The measurement implies that an unknown process depleted oxygen-16 from the Sun's disk of protoplanetary material prior to the coalescence of dust grains that formed the Earth.

What spacecraft contained data to determine the oxygen content of the Sun?

Newton came to realize that the effects of gravity might be observed in different ways at larger distances. In particular, Newton determined that the acceleration of the Moon around the Earth could be ascribed to the same force of gravity if the acceleration due to gravity decreased as an inverse square law. Further, Newton realized that the acceleration due to gravity is proportional to the mass of the attracting body. Combining these ideas gives a formula that relates the mass () and the radius () of the Earth to the gravitational acceleration:

Read this: Since about the year 2000, a growing number of Internet pharmacies have been established worldwide. Many of these pharmacies are similar to community pharmacies, and in fact, many of them are actually operated by brick-and-mortar community pharmacies that serve consumers online and those that walk in their door. The primary difference is the method by which the medications are requested and received. Some customers consider this to be more convenient and private method rather than traveling to a community drugstore where another customer might overhear about the drugs that they take. Internet pharmacies (also known as online pharmacies) are also recommended to some patients by their physicians if they are homebound.

Connection-oriented transmission requires a setup phase in each involved node before any packet is transferred to establish the parameters of communication. The packets include a connection identifier rather than address information and are negotiated between endpoints so that they are delivered in order and with error checking. Address information is only transferred to each node during the connection set-up phase, when the route to the destination is discovered and an entry is added to the switching table in each network node through which the connection passes. The signaling protocols used allow the application to specify its requirements and discover link parameters. Acceptable values for service parameters may be negotiated. Routing a packet requires the node to look up the connection id in a table. The packet header can be small, as it only needs to contain this code and any information, such as length, timestamp, or sequence number, which is different for different packets.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): How is error checking involved in delivery?

The most commonly used reduction is a polynomial-time reduction. This means that the reduction process takes polynomial time. For example, the problem of squaring an integer can be reduced to the problem of multiplying two integers. This means an algorithm for multiplying two integers can be used to square an integer. Indeed, this can be done by giving the same input to both inputs of the multiplication algorithm. Thus we see that squaring is not more difficult than multiplication, since squaring can be reduced to multiplication.

Harvard has the largest university endowment in the world. As of September 2011[update], it had nearly regained the loss suffered during the 2008 recession. It was worth $32 billion in 2011, up from $28 billion in September 2010 and $26 billion in 2009. It suffered about 30% loss in 2008-09. In December 2008, Harvard announced that its endowment had lost 22% (approximately $8 billion) from July to October 2008, necessitating budget cuts. Later reports suggest the loss was actually more than double that figure, a reduction of nearly 50% of its endowment in the first four months alone. Forbes in March 2009 estimated the loss to be in the range of $12 billion. One of the most visible results of Harvard's attempt to re-balance its budget was their halting of construction of the $1.2 billion Allston Science Complex that had been scheduled to be completed by 2011, resulting in protests from local residents. As of 2012[update], Harvard University had a total financial aid reserve of $159 million for students, and a Pell Grant reserve of $4.093 million available for disbursement.

What amount did Harvard cut from their 2012 financial aid reserve?


This shift has already commenced in some countries; for instance, pharmacists in Australia receive remuneration from the Australian Government for conducting comprehensive Home Medicines Reviews. In Canada, pharmacists in certain provinces have limited prescribing rights (as in Alberta and British Columbia) or are remunerated by their provincial government for expanded services such as medications reviews (Medschecks in Ontario). In the United Kingdom, pharmacists who undertake additional training are obtaining prescribing rights and this is because of pharmacy education. They are also being paid for by the government for medicine use reviews. In Scotland the pharmacist can write prescriptions for Scottish registered patients of their regular medications, for the majority of drugs, except for controlled drugs, when the patient is unable to see their doctor, as could happen if they are away from home or the doctor is unavailable. In the United States, pharmaceutical care or clinical pharmacy has had an evolving influence on the practice of pharmacy. Moreover, the Doctor of Pharmacy (Pharm. D.) degree is now required before entering practice and some pharmacists now complete one or two years of residency or fellowship training following graduation. In addition, consultant pharmacists, who traditionally operated primarily in nursing homes are now expanding into direct consultation with patients, under the banner of "senior care pharmacy."

The internal cavity forms: a mouth that can usually be closed by muscles; a pharynx ("throat"); a wider area in the center that acts as a stomach; and a system of internal canals. These branch through the mesoglea to the most active parts of the animal: the mouth and pharynx; the roots of the tentacles, if present; all along the underside of each comb row; and four branches round the sensory complex at the far end from the mouth – two of these four branches terminate in anal pores. The inner surface of the cavity is lined with an epithelium, the gastrodermis. The mouth and pharynx have both cilia and well-developed muscles. In other parts of the canal system, the gastrodermis is different on the sides nearest to and furthest from the organ that it supplies. The nearer side is composed of tall nutritive cells that store nutrients in vacuoles (internal compartments), germ cells that produce eggs or sperm, and photocytes that produce bioluminescence. The side furthest from the organ is covered with ciliated cells that circulate water through the canals, punctuated by ciliary rosettes, pores that are surrounded by double whorls of cilia and connect to the mesoglea.

Several barriers protect organisms from infection, including mechanical, chemical, and biological barriers. The waxy cuticle of many leaves, the exoskeleton of insects, the shells and membranes of externally deposited eggs, and skin are examples of mechanical barriers that are the first line of defense against infection. However, as organisms cannot be completely sealed from their environments, other systems act to protect body openings such as the lungs, intestines, and the genitourinary tract. In the lungs, coughing and sneezing mechanically eject pathogens and other irritants from the respiratory tract. The flushing action of tears and urine also mechanically expels pathogens, while mucus secreted by the respiratory and gastrointestinal tract serves to trap and entangle microorganisms.

Answer this question, if possible (if impossible, reply "unanswerable"): What is the last line of defense against infection?

Oxygen:

This combination of cancellations and σ and π overlaps results in dioxygen's double bond character and reactivity, and a triplet electronic ground state. An electron configuration with two unpaired electrons as found in dioxygen (see the filled π* orbitals in the diagram), orbitals that are of equal energy—i.e., degenerate—is a configuration termed a spin triplet state. Hence, the ground state of the O
2 molecule is referred to as triplet oxygen.[b] The highest energy, partially filled orbitals are antibonding, and so their filling weakens the bond order from three to two. Because of its unpaired electrons, triplet oxygen reacts only slowly with most organic molecules, which have paired electron spins; this prevents spontaneous combustion.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What are the weakly filled higher orbitals of oxygen?

"Southern California" is not a formal geographic designation, and definitions of what constitutes southern California vary. Geographically, California's north-south midway point lies at exactly 37° 9' 58.23" latitude, around 11 miles (18 km) south of San Jose; however, this does not coincide with popular use of the term. When the state is divided into two areas (northern and southern California), the term "southern California" usually refers to the ten southern-most counties of the state. This definition coincides neatly with the county lines at 35° 47′ 28″ north latitude, which form the northern borders of San Luis Obispo, Kern, and San Bernardino counties. Another definition for southern California uses Point Conception and the Tehachapi Mountains as the northern boundary.

Immune system:

Neutrophils and macrophages are phagocytes that travel throughout the body in pursuit of invading pathogens. Neutrophils are normally found in the bloodstream and are the most abundant type of phagocyte, normally representing 50% to 60% of the total circulating leukocytes. During the acute phase of inflammation, particularly as a result of bacterial infection, neutrophils migrate toward the site of inflammation in a process called chemotaxis, and are usually the first cells to arrive at the scene of infection. Macrophages are versatile cells that reside within tissues and produce a wide array of chemicals including enzymes, complement proteins, and regulatory factors such as interleukin 1. Macrophages also act as scavengers, ridding the body of worn-out cells and other debris, and as antigen-presenting cells that activate the adaptive immune system.

Civil disobedience:

One of its earliest massive implementations was brought about by Egyptians against the British occupation in the 1919 Revolution. Civil disobedience is one of the many ways people have rebelled against what they deem to be unfair laws. It has been used in many nonviolent resistance movements in India (Gandhi's campaigns for independence from the British Empire), in Czechoslovakia's Velvet Revolution and in East Germany to oust their communist governments, In South Africa in the fight against apartheid, in the American Civil Rights Movement, in the Singing Revolution to bring independence to the Baltic countries from the Soviet Union, recently with the 2003 Rose Revolution in Georgia and the 2004 Orange Revolution in Ukraine, among other various movements worldwide.

Virtually all nuclear power plants generate electricity by heating water to provide steam that drives a turbine connected to an electrical generator. Nuclear-powered ships and submarines either use a steam turbine directly for main propulsion, with generators providing auxiliary power, or else employ turbo-electric transmission, where the steam drives a turbo generator set with propulsion provided by electric motors. A limited number of steam turbine railroad locomotives were manufactured. Some non-condensing direct-drive locomotives did meet with some success for long haul freight operations in Sweden and for express passenger work in Britain, but were not repeated. Elsewhere, notably in the U.S.A., more advanced designs with electric transmission were built experimentally, but not reproduced. It was found that steam turbines were not ideally suited to the railroad environment and these locomotives failed to oust the classic reciprocating steam unit in the way that modern diesel and electric traction has done.[citation needed]

What is it called when steam propels a turbo generator with electric motor propulsion?

In its focus on the Caliphate, the party takes a different view of Muslim history than some other Islamists such as Muhammad Qutb. HT sees Islam's pivotal turning point as occurring not with the death of Ali, or one of the other four rightly guided Caliphs in the 7th century, but with the abolition of the Ottoman Caliphate in 1924. This is believed to have ended the true Islamic system, something for which it blames "the disbelieving (Kafir) colonial powers" working through Turkish modernist Mustafa Kemal Atatürk.

The abolition of the Ottoman Caliphate is believed to have ended what system?


Steam engine:

Around 1800 Richard Trevithick and, separately, Oliver Evans in 1801 introduced engines using high-pressure steam; Trevithick obtained his high-pressure engine patent in 1802. These were much more powerful for a given cylinder size than previous engines and could be made small enough for transport applications. Thereafter, technological developments and improvements in manufacturing techniques (partly brought about by the adoption of the steam engine as a power source) resulted in the design of more efficient engines that could be smaller, faster, or more powerful, depending on the intended application.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". In what year did Richard Trevithick patent his device?


There are also many places commemorating the heroic history of Warsaw. Pawiak, an infamous German Gestapo prison now occupied by a Mausoleum of Memory of Martyrdom and the museum, is only the beginning of a walk in the traces of Heroic City. The Warsaw Citadel, an impressive 19th-century fortification built after the defeat of the November Uprising, was a place of martyr for the Poles. Another important monument, the statue of Little Insurgent located at the ramparts of the Old Town, commemorates the children who served as messengers and frontline troops in the Warsaw Uprising, while the impressive Warsaw Uprising Monument by Wincenty Kućma was erected in memory of the largest insurrection of World War II.

Read this: In Japan, at the end of the Asuka period (538–710) and the early Nara period (710–794), the men who fulfilled roles similar to those of modern pharmacists were highly respected. The place of pharmacists in society was expressly defined in the Taihō Code (701) and re-stated in the Yōrō Code (718). Ranked positions in the pre-Heian Imperial court were established; and this organizational structure remained largely intact until the Meiji Restoration (1868). In this highly stable hierarchy, the pharmacists—and even pharmacist assistants—were assigned status superior to all others in health-related fields such as physicians and acupuncturists. In the Imperial household, the pharmacist was even ranked above the two personal physicians of the Emperor.

Where did the pharmacist stand in relation to the Emperor?

Politically, Victoria has 37 seats in the Australian House of Representatives and 12 seats in the Australian Senate. At state level, the Parliament of Victoria consists of the Legislative Assembly (the lower house) and the Legislative Council (the upper house). Victoria is currently governed by the Labor Party, with Daniel Andrews the current Premier. The personal representative of the Queen of Australia in the state is the Governor of Victoria, currently Linda Dessau. Local government is concentrated in 79 municipal districts, including 33 cities, although a number of unincorporated areas still exist, which are administered directly by the state.

Building activity occurred in numerous noble palaces and churches during the later decades of the 17th century. One of the best examples of this architecture are Krasiński Palace (1677–1683), Wilanów Palace (1677–1696) and St. Kazimierz Church (1688–1692). The most impressive examples of rococo architecture are Czapski Palace (1712–1721), Palace of the Four Winds (1730s) and Visitationist Church (façade 1728–1761). The neoclassical architecture in Warsaw can be described by the simplicity of the geometrical forms teamed with a great inspiration from the Roman period. Some of the best examples of the neoclassical style are the Palace on the Water (rebuilt 1775–1795), Królikarnia (1782–1786), Carmelite Church (façade 1761–1783) and Evangelical Holy Trinity Church (1777–1782). The economic growth during the first years of Congress Poland caused a rapid rise architecture. The Neoclassical revival affected all aspects of architecture, the most notable are the Great Theater (1825–1833) and buildings located at Bank Square (1825–1828).

When was the Palace on the Water rebuilt?


Harvard has purchased tracts of land in Allston, a walk across the Charles River from Cambridge, with the intent of major expansion southward. The university now owns approximately fifty percent more land in Allston than in Cambridge. Proposals to connect the Cambridge campus with the new Allston campus include new and enlarged bridges, a shuttle service and/or a tram. Plans also call for sinking part of Storrow Drive (at Harvard's expense) for replacement with park land and pedestrian access to the Charles River, as well as the construction of bike paths, and buildings throughout the Allston campus. The institution asserts that such expansion will benefit not only the school, but surrounding community, pointing to such features as the enhanced transit infrastructure, possible shuttles open to the public, and park space which will also be publicly accessible.

On 1 July 1851, writs were issued for the election of the first Victorian Legislative Council, and the absolute independence of Victoria from New South Wales was established proclaiming a new Colony of Victoria. Days later, still in 1851 gold was discovered near Ballarat, and subsequently at Bendigo. Later discoveries occurred at many sites across Victoria. This triggered one of the largest gold rushes the world has ever seen. The colony grew rapidly in both population and economic power. In ten years the population of Victoria increased sevenfold from 76,000 to 540,000. All sorts of gold records were produced including the "richest shallow alluvial goldfield in the world" and the largest gold nugget. Victoria produced in the decade 1851–1860 20 million ounces of gold, one third of the world's output[citation needed].

Packet switching:

The CYCLADES packet switching network was a French research network designed and directed by Louis Pouzin. First demonstrated in 1973, it was developed to explore alternatives to the early ARPANET design and to support network research generally. It was the first network to make the hosts responsible for reliable delivery of data, rather than the network itself, using unreliable datagrams and associated end-to-end protocol mechanisms. Concepts of this network influenced later ARPANET architecture.

Since its founding, the EU has operated among an increasing plurality of national and globalising legal systems. This has meant both the European Court of Justice and the highest national courts have had to develop principles to resolve conflicts of laws between different systems. Within the EU itself, the Court of Justice's view is that if EU law conflicts with a provision of national law, then EU law has primacy. In the first major case in 1964, Costa v ENEL, a Milanese lawyer, and former shareholder of an energy company, named Mr Costa refused to pay his electricity bill to Enel, as a protest against the nationalisation of the Italian energy corporations. He claimed the Italian nationalisation law conflicted with the Treaty of Rome, and requested a reference be made to both the Italian Constitutional Court and the Court of Justice under TFEU article 267. The Italian Constitutional Court gave an opinion that because the nationalisation law was from 1962, and the treaty was in force from 1958, Costa had no claim. By contrast, the Court of Justice held that ultimately the Treaty of Rome in no way prevented energy nationalisation, and in any case under the Treaty provisions only the Commission could have brought a claim, not Mr Costa. However, in principle, Mr Costa was entitled to plead that the Treaty conflicted with national law, and the court would have a duty to consider his claim to make a reference if there would be no appeal against its decision. The Court of Justice, repeating its view in Van Gend en Loos, said member states "albeit within limited spheres, have restricted their sovereign rights and created a body of law applicable both to their nationals and to themselves" on the "basis of reciprocity". EU law would not "be overridden by domestic legal provisions, however framed... without the legal basis of the community itself being called into question." This meant any "subsequent unilateral act" of the member state inapplicable. Similarly, in Amministrazione delle Finanze v Simmenthal SpA, a company, Simmenthal SpA, claimed that a public health inspection fee under an Italian law of 1970 for importing beef from France to Italy was contrary to two Regulations from 1964 and 1968. In "accordance with the principle of the precedence of Community law," said the Court of Justice, the "directly applicable measures of the institutions" (such as the Regulations in the case) "render automatically inapplicable any conflicting provision of current national law". This was necessary to prevent a "corresponding denial" of Treaty "obligations undertaken unconditionally and irrevocably by member states", that could "imperil the very foundations of the" EU. But despite the views of the Court of Justice, the national courts of member states have not accepted the same analysis.

Advances in polynomial algebra were made by mathematicians during the Yuan era. The mathematician Zhu Shijie (1249–1314) solved simultaneous equations with up to four unknowns using a rectangular array of coefficients, equivalent to modern matrices. Zhu used a method of elimination to reduce the simultaneous equations to a single equation with only one unknown. His method is described in the Jade Mirror of the Four Unknowns, written in 1303. The opening pages contain a diagram of Pascal's triangle. The summation of a finite arithmetic series is also covered in the book.

The Rhine was not known to Herodotus and first enters the historical period in the 1st century BC in Roman-era geography. At that time, it formed the boundary between Gaul and Germania. The Upper Rhine had been part of the areal of the late Hallstatt culture since the 6th century BC, and by the 1st century BC, the areal of the La Tène culture covered almost its entire length, forming a contact zone with the Jastorf culture, i.e. the locus of early Celtic-Germanic cultural contact. In Roman geography, the Rhine formed the boundary between Gallia and Germania by definition; e.g. Maurus Servius Honoratus, Commentary on the Aeneid of Vergil (8.727) (Rhenus) fluvius Galliae, qui Germanos a Gallia dividit "(The Rhine is a) river of Gaul, which divides the Germanic people from Gaul."

In the laboratory, biostratigraphers analyze rock samples from outcrop and drill cores for the fossils found in them. These fossils help scientists to date the core and to understand the depositional environment in which the rock units formed. Geochronologists precisely date rocks within the stratigraphic section in order to provide better absolute bounds on the timing and rates of deposition. Magnetic stratigraphers look for signs of magnetic reversals in igneous rock units within the drill cores. Other scientists perform stable isotope studies on the rocks to gain information about past climate.

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.

One of FIS' agenda items was to force women to start doing what?


It has been argued that the term "civil disobedience" has always suffered from ambiguity and in modern times, become utterly debased. Marshall Cohen notes, "It has been used to describe everything from bringing a test-case in the federal courts to taking aim at a federal official.

Civil disobedients have chosen a variety of different illegal acts. Bedau writes, "There is a whole class of acts, undertaken in the name of civil disobedience, which, even if they were widely practiced, would in themselves constitute hardly more than a nuisance (e.g. trespassing at a nuclear-missile installation)...Such acts are often just a harassment and, at least to the bystander, somewhat inane...The remoteness of the connection between the disobedient act and the objectionable law lays such acts open to the charge of ineffectiveness and absurdity." Bedau also notes, though, that the very harmlessness of such entirely symbolic illegal protests toward public policy goals may serve a propaganda purpose. Some civil disobedients, such as the proprietors of illegal medical cannabis dispensaries and Voice in the Wilderness, which brought medicine to Iraq without the permission of the U.S. Government, directly achieve a desired social goal (such as the provision of medication to the sick) while openly breaking the law.

Tymnet was an international data communications network headquartered in San Jose, CA that utilized virtual call packet switched technology and used X.25, SNA/SDLC, BSC and ASCII interfaces to connect host computers (servers)at thousands of large companies, educational institutions, and government agencies. Users typically connected via dial-up connections or dedicated async connections. The business consisted of a large public network that supported dial-up users and a private network business that allowed government agencies and large companies (mostly banks and airlines) to build their own dedicated networks. The private networks were often connected via gateways to the public network to reach locations not on the private network. Tymnet was also connected to dozens of other public networks in the U.S. and internationally via X.25/X.75 gateways. (Interesting note: Tymnet was not named after Mr. Tyme. Another employee suggested the name.)

Read this: In contrast, during wake periods differentiated effector cells, such as cytotoxic natural killer cells and CTLs (cytotoxic T lymphocytes), peak in order to elicit an effective response against any intruding pathogens. As well during awake active times, anti-inflammatory molecules, such as cortisol and catecholamines, peak. There are two theories as to why the pro-inflammatory state is reserved for sleep time. First, inflammation would cause serious cognitive and physical impairments if it were to occur during wake times. Second, inflammation may occur during sleep times due to the presence of melatonin. Inflammation causes a great deal of oxidative stress and the presence of melatonin during sleep times could actively counteract free radical production during this time.

There are many instances where a practitioner issues a prescription, brokered by an Internet server, for a controlled substance to a "patient" s/he has never met.[citation needed] In the United States, in order for a prescription for a controlled substance to be valid, it must be issued for a legitimate medical purpose by a licensed practitioner acting in the course of legitimate doctor-patient relationship.

Uniflow engines attempt to remedy the difficulties arising from the usual counterflow cycle where, during each stroke, the port and the cylinder walls will be cooled by the passing exhaust steam, whilst the hotter incoming admission steam will waste some of its energy in restoring working temperature. The aim of the uniflow is to remedy this defect and improve efficiency by providing an additional port uncovered by the piston at the end of each stroke making the steam flow only in one direction. By this means, the simple-expansion uniflow engine gives efficiency equivalent to that of classic compound systems with the added advantage of superior part-load performance, and comparable efficiency to turbines for smaller engines below one thousand horsepower. However, the thermal expansion gradient uniflow engines produce along the cylinder wall gives practical difficulties.[citation needed]. The Quasiturbine is a uniflow rotary steam engine where steam intakes in hot areas, while exhausting in cold areas.

Immune system:

Immunology is a science that examines the structure and function of the immune system. It originates from medicine and early studies on the causes of immunity to disease. The earliest known reference to immunity was during the plague of Athens in 430 BC. Thucydides noted that people who had recovered from a previous bout of the disease could nurse the sick without contracting the illness a second time. In the 18th century, Pierre-Louis Moreau de Maupertuis made experiments with scorpion venom and observed that certain dogs and mice were immune to this venom. This and other observations of acquired immunity were later exploited by Louis Pasteur in his development of vaccination and his proposed germ theory of disease. Pasteur's theory was in direct opposition to contemporary theories of disease, such as the miasma theory. It was not until Robert Koch's 1891 proofs, for which he was awarded a Nobel Prize in 1905, that microorganisms were confirmed as the cause of infectious disease. Viruses were confirmed as human pathogens in 1901, with the discovery of the yellow fever virus by Walter Reed.

Telenet was the first FCC-licensed public data network in the United States. It was founded by former ARPA IPTO director Larry Roberts as a means of making ARPANET technology public. He had tried to interest AT&T in buying the technology, but the monopoly's reaction was that this was incompatible with their future. Bolt, Beranack and Newman (BBN) provided the financing. It initially used ARPANET technology but changed the host interface to X.25 and the terminal interface to X.29. Telenet designed these protocols and helped standardize them in the CCITT. Telenet was incorporated in 1973 and started operations in 1975. It went public in 1979 and was then sold to GTE.

The zeta function is closely related to prime numbers. For example, the aforementioned fact that there are infinitely many primes can also be seen using the zeta function: if there were only finitely many primes then ζ(1) would have a finite value. However, the harmonic series 1 + 1/2 + 1/3 + 1/4 + ... diverges (i.e., exceeds any given number), so there must be infinitely many primes. Another example of the richness of the zeta function and a glimpse of modern algebraic number theory is the following identity (Basel problem), due to Euler,

Lobates have eight comb-rows, originating at the aboral pole and usually not extending beyond the body to the lobes; in species with (four) auricles, the cilia edging the auricles are extensions of cilia in four of the comb rows. Most lobates are quite passive when moving through the water, using the cilia on their comb rows for propulsion, although Leucothea has long and active auricles whose movements also contribute to propulsion. Members of the lobate genera Bathocyroe and Ocyropsis can escape from danger by clapping their lobes, so that the jet of expelled water drives them backwards very quickly. Unlike cydippids, the movements of lobates' combs are coordinated by nerves rather than by water disturbances created by the cilia, yet combs on the same row beat in the same Mexican wave style as the mechanically coordinated comb rows of cydippids and beroids. This may have enabled lobates to grow larger than cydippids and to have shapes that are less egg-like.

How are most cilia when moving through the water?


Sociologist Jake Rosenfield of the University of Washington asserts that the decline of organized labor in the United States has played a more significant role in expanding the income gap than technological changes and globalization, which were also experienced by other industrialized nations that didn't experience steep surges in inequality. He points out that nations with high rates of unionization, particularly in Scandinavia, have very low levels of inequality, and concludes "the historical pattern is clear; the cross-national pattern is clear: high inequality goes hand-in-hand with weak labor movements and vice-versa."

Read this: Around 2.5 million years ago (ending 11,600 years ago) was the geological period of the Ice Ages. Since approximately 600,000 years ago, six major Ice Ages have occurred, in which sea level dropped 120 m (390 ft) and much of the continental margins became exposed. In the Early Pleistocene, the Rhine followed a course to the northwest, through the present North Sea. During the so-called Anglian glaciation (~450,000 yr BP, marine oxygen isotope stage 12), the northern part of the present North Sea was blocked by the ice and a large lake developed, that overflowed through the English Channel. This caused the Rhine's course to be diverted through the English Channel. Since then, during glacial times, the river mouth was located offshore of Brest, France and rivers, like the Thames and the Seine, became tributaries to the Rhine. During interglacials, when sea level rose to approximately the present level, the Rhine built deltas, in what is now the Netherlands.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What period was 2.5 million years ago?


Inflammation is one of the first responses of the immune system to infection. The symptoms of inflammation are redness, swelling, heat, and pain, which are caused by increased blood flow into tissue. Inflammation is produced by eicosanoids and cytokines, which are released by injured or infected cells. Eicosanoids include prostaglandins that produce fever and the dilation of blood vessels associated with inflammation, and leukotrienes that attract certain white blood cells (leukocytes). Common cytokines include interleukins that are responsible for communication between white blood cells; chemokines that promote chemotaxis; and interferons that have anti-viral effects, such as shutting down protein synthesis in the host cell. Growth factors and cytotoxic factors may also be released. These cytokines and other chemicals recruit immune cells to the site of infection and promote healing of any damaged tissue following the removal of pathogens.

However, this definition is disputed by Thoreau's political philosophy pitching the conscience vs. the collective. The individual is the final judge of right and wrong. More than this, since only individuals act, only individuals can act unjustly. When the government knocks on the door, it is an individual in the form of a postman or tax collector whose hand hits the wood. Before Thoreau’s imprisonment, when a confused taxman had wondered aloud about how to handle his refusal to pay, Thoreau had advised, “Resign.” If a man chose to be an agent of injustice, then Thoreau insisted on confronting him with the fact that he was making a choice. But if government is “the voice of the people,” as it is often called, shouldn’t that voice be heeded? Thoreau admits that government may express the will of the majority but it may also express nothing more than the will of elite politicians. Even a good form of government is “liable to be abused and perverted before the people can act through it.” Moreover, even if a government did express the voice of the people, this fact would not compel the obedience of individuals who disagree with what is being said. The majority may be powerful but it is not necessarily right. What, then, is the proper relationship between the individual and the government?

Read this: Price controls exacerbated the crisis in the US. The system limited the price of "old oil" (that which had already been discovered) while allowing newly discovered oil to be sold at a higher price to encourage investment. Predictably, old oil was withdrawn from the market, creating greater scarcity. The rule also discouraged development of alternative energies. The rule had been intended to promote oil exploration. Scarcity was addressed by rationing (as in many countries). Motorists faced long lines at gas stations beginning in summer 1972 and increasing by summer 1973.

The length of the Rhine is conventionally measured in "Rhine-kilometers" (Rheinkilometer), a scale introduced in 1939 which runs from the Old Rhine Bridge at Constance (0 km) to Hoek van Holland (1036.20 km). The river length is significantly shortened from the river's natural course due to number of canalisation projects completed in the 19th and 20th century.[note 7] The "total length of the Rhine", to the inclusion of Lake Constance and the Alpine Rhine is more difficult to measure objectively; it was cited as 1,232 kilometres (766 miles) by the Dutch Rijkswaterstaat in 2010.[note 1]

How long is Lake Constance?

Stage 3 is the final stage of the bill and is considered at a meeting of the whole Parliament. This stage comprises two parts: consideration of amendments to the bill as a general debate, and a final vote on the bill. Opposition members can table "wrecking amendments" to the bill, designed to thwart further progress and take up parliamentary time, to cause the bill to fall without a final vote being taken. After a general debate on the final form of the bill, members proceed to vote at Decision Time on whether they agree to the general principles of the final bill.

What vote on a bill takes place in Stage 3?


In connectionless mode each packet includes complete addressing information. The packets are routed individually, sometimes resulting in different paths and out-of-order delivery. Each packet is labeled with a destination address, source address, and port numbers. It may also be labeled with the sequence number of the packet. This precludes the need for a dedicated path to help the packet find its way to its destination, but means that much more information is needed in the packet header, which is therefore larger, and this information needs to be looked up in power-hungry content-addressable memory. Each packet is dispatched and may go via different routes; potentially, the system has to do as much work for every packet as the connection-oriented system has to do in connection set-up, but with less information as to the application's requirements. At the destination, the original message/data is reassembled in the correct order, based on the packet sequence number. Thus a virtual connection, also known as a virtual circuit or byte stream is provided to the end-user by a transport layer protocol, although intermediate network nodes only provides a connectionless network layer service.

The mayor of Warsaw is called President. Generally, in Poland, the mayors of bigger cities are called presidents – i.e. such cities, which have over 100,000 people or these, where already was president before 1990. The first Warsaw President was Jan Andrzej Menich (1695–1696). Between 1975 and 1990 the Warsaw Presidents was simultaneously the Warsaw Voivode. Since 1990 the President of Warsaw had been elected by the City council. In the years of 1994–1999 the mayor of the district Centrum automatically was designated as the President of Warsaw: the mayor of Centrum was elected by the district council of Centrum and the council was elected only by the Centrum residents. Since 2002 the President of Warsaw is elected by all of the citizens of Warsaw.

Not a maritime power, and not a nation-state, as it would eventually become, Germany’s participation in Western imperialism was negligible until the late 19th century. The participation of Austria was primarily as a result of Habsburg control of the First Empire, the Spanish throne, and other royal houses.[further explanation needed] After the defeat of Napoleon, who caused the dissolution of that Holy Roman Empire, Prussia and the German states continued to stand aloof from imperialism, preferring to manipulate the European system through the Concert of Europe. After Prussia unified the other states into the second German Empire after the Franco-German War, its long-time Chancellor, Otto von Bismarck (1862–90), long opposed colonial acquisitions, arguing that the burden of obtaining, maintaining, and defending such possessions would outweigh any potential benefits. He felt that colonies did not pay for themselves, that the German bureaucratic system would not work well in the tropics and the diplomatic disputes over colonies would distract Germany from its central interest, Europe itself.

Read this: Funding for private schools is generally provided through student tuition, endowments, scholarship/voucher funds, and donations and grants from religious organizations or private individuals. Government funding for religious schools is either subject to restrictions or possibly forbidden, according to the courts' interpretation of the Establishment Clause of the First Amendment or individual state Blaine Amendments. Non-religious private schools theoretically could qualify for such funding without hassle, preferring the advantages of independent control of their student admissions and course content instead of the public funding they could get with charter status.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What amendment to the United States Constitution governs government funding of religious schools?


A term used originally in derision, Huguenot has unclear origins. Various hypotheses have been promoted. The nickname may have been a combined reference to the Swiss politician Besançon Hugues (died 1532) and the religiously conflicted nature of Swiss republicanism in his time, using a clever derogatory pun on the name Hugues by way of the Dutch word Huisgenoten (literally housemates), referring to the connotations of a somewhat related word in German Eidgenosse (Confederates as in "a citizen of one of the states of the Swiss Confederacy"). Geneva was John Calvin's adopted home and the centre of the Calvinist movement. In Geneva, Hugues, though Catholic, was a leader of the "Confederate Party", so called because it favoured independence from the Duke of Savoy through an alliance between the city-state of Geneva and the Swiss Confederation. The label Huguenot was purportedly first applied in France to those conspirators (all of them aristocratic members of the Reformed Church) involved in the Amboise plot of 1560: a foiled attempt to wrest power in France from the influential House of Guise. The move would have had the side effect of fostering relations with the Swiss. Thus, Hugues plus Eidgenosse by way of Huisgenoten supposedly became Huguenot, a nickname associating the Protestant cause with politics unpopular in France.[citation needed]

In 1700 several hundred French Huguenots migrated from England to the colony of Virginia, where the English Crown had promised them land grants in Lower Norfolk County. When they arrived, colonial authorities offered them instead land 20 miles above the falls of the James River, at the abandoned Monacan village known as Manakin Town, now in Powhatan County. Some settlers landed in present-day Chesterfield County. On 12 May 1705, the Virginia General Assembly passed an act to naturalise the 148 Huguenots still resident at Manakintown. Of the original 390 settlers in the isolated settlement, many had died; others lived outside town on farms in the English style; and others moved to different areas. Gradually they intermarried with their English neighbors. Through the 18th and 19th centuries, descendants of the French migrated west into the Piedmont, and across the Appalachian Mountains into the West of what became Kentucky, Tennessee, Missouri, and other states. In the Manakintown area, the Huguenot Memorial Bridge across the James River and Huguenot Road were named in their honor, as were many local features, including several schools, including Huguenot High School.

While studying law and philosophy in England and Germany, Iqbal became a member of the London branch of the All India Muslim League. He came back to Lahore in 1908. While dividing his time between law practice and philosophical poetry, Iqbal had remained active in the Muslim League. He did not support Indian involvement in World War I and remained in close touch with Muslim political leaders such as Muhammad Ali Johar and Muhammad Ali Jinnah. He was a critic of the mainstream Indian nationalist and secularist Indian National Congress. Iqbal's seven English lectures were published by Oxford University press in 1934 in a book titled The Reconstruction of Religious Thought in Islam. These lectures dwell on the role of Islam as a religion as well as a political and legal philosophy in the modern age.

What organization did Iqbal join in London?


Read this: In the centre of Basel, the first major city in the course of the stream, is located the "Rhine knee"; this is a major bend, where the overall direction of the Rhine changes from West to North. Here the High Rhine ends. Legally, the Central Bridge is the boundary between High and Upper Rhine. The river now flows North as Upper Rhine through the Upper Rhine Plain, which is about 300 km long and up to 40 km wide. The most important tributaries in this area are the Ill below of Strasbourg, the Neckar in Mannheim and the Main across from Mainz. In Mainz, the Rhine leaves the Upper Rhine Valley and flows through the Mainz Basin.

What is the bend called where the overall direction of the Rhine changes from East to North?

Pharmacy informatics is the combination of pharmacy practice science and applied information science. Pharmacy informaticists work in many practice areas of pharmacy, however, they may also work in information technology departments or for healthcare information technology vendor companies. As a practice area and specialist domain, pharmacy informatics is growing quickly to meet the needs of major national and international patient information projects and health system interoperability goals. Pharmacists in this area are trained to participate in medication management system development, deployment and optimization.

Despite periodic repression, the Brotherhood has become one of the most influential movements in the Islamic world, particularly in the Arab world. For many years it was described as "semi-legal" and was the only opposition group in Egypt able to field candidates during elections. In the Egyptian parliamentary election, 2011–2012, the political parties identified as "Islamist" (the Brotherhood's Freedom and Justice Party, Salafi Al-Nour Party and liberal Islamist Al-Wasat Party) won 75% of the total seats. Mohamed Morsi, an Islamist democrat of Muslim Brotherhood, was the first democratically elected president of Egypt. He was deposed during the 2013 Egyptian coup d'état.

The Amazon rainforest (Portuguese: Floresta Amazônica or Amazônia; Spanish: Selva Amazónica, Amazonía or usually Amazonia; French: Forêt amazonienne; Dutch: Amazoneregenwoud), also known in English as Amazonia or the Amazon Jungle, is a moist broadleaf forest that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 square kilometres (2,700,000 sq mi), of which 5,500,000 square kilometres (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. States or departments in four nations contain "Amazonas" in their names. The Amazon represents over half of the planet's remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species.

Amazonia or the Amazon jungle are no longer used to refer to what?


An evasion strategy used by several pathogens to avoid the innate immune system is to hide within the cells of their host (also called intracellular pathogenesis). Here, a pathogen spends most of its life-cycle inside host cells, where it is shielded from direct contact with immune cells, antibodies and complement. Some examples of intracellular pathogens include viruses, the food poisoning bacterium Salmonella and the eukaryotic parasites that cause malaria (Plasmodium falciparum) and leishmaniasis (Leishmania spp.). Other bacteria, such as Mycobacterium tuberculosis, live inside a protective capsule that prevents lysis by complement. Many pathogens secrete compounds that diminish or misdirect the host's immune response. Some bacteria form biofilms to protect themselves from the cells and proteins of the immune system. Such biofilms are present in many successful infections, e.g., the chronic Pseudomonas aeruginosa and Burkholderia cenocepacia infections characteristic of cystic fibrosis. Other bacteria generate surface proteins that bind to antibodies, rendering them ineffective; examples include Streptococcus (protein G), Staphylococcus aureus (protein A), and Peptostreptococcus magnus (protein L).

The unproven Riemann hypothesis, dating from 1859, states that except for s = −2, −4, ..., all zeroes of the ζ-function have real part equal to 1/2. The connection to prime numbers is that it essentially says that the primes are as regularly distributed as possible.[clarification needed] From a physical viewpoint, it roughly states that the irregularity in the distribution of primes only comes from random noise. From a mathematical viewpoint, it roughly states that the asymptotic distribution of primes (about x/log x of numbers less than x are primes, the prime number theorem) also holds for much shorter intervals of length about the square root of x (for intervals near x). This hypothesis is generally believed to be correct. In particular, the simplest assumption is that primes should have no significant irregularities without good reason.

Answer this question, if possible (if impossible, reply "unanswerable"): What does the Riemann hypothesis state the source of irregularity in the distribution of points comes from?


Extension causes the rock units as a whole to become longer and thinner. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. Normal faults drop rock units that are higher below those that are lower. This typically results in younger units being placed below older units. Stretching of units can result in their thinning; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter. Rocks at the depth to be ductilely stretched are often also metamorphosed. These stretched rocks can also pinch into lenses, known as boudins, after the French word for "sausage", because of their visual similarity.

Answer this question, if possible (if impossible, reply "unanswerable"): How does sediment make rock fall?


A third type of conjectures concerns aspects of the distribution of primes. It is conjectured that there are infinitely many twin primes, pairs of primes with difference 2 (twin prime conjecture). Polignac's conjecture is a strengthening of that conjecture, it states that for every positive integer n, there are infinitely many pairs of consecutive primes that differ by 2n. It is conjectured there are infinitely many primes of the form n2 + 1. These conjectures are special cases of the broad Schinzel's hypothesis H. Brocard's conjecture says that there are always at least four primes between the squares of consecutive primes greater than 2. Legendre's conjecture states that there is a prime number between n2 and (n + 1)2 for every positive integer n. It is implied by the stronger Cramér's conjecture.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Of what form is the infinite amount of primes that comprise the special cases of Schinzel's hypothesis?


This shift has already commenced in some countries; for instance, pharmacists in Australia receive remuneration from the Australian Government for conducting comprehensive Home Medicines Reviews. In Canada, pharmacists in certain provinces have limited prescribing rights (as in Alberta and British Columbia) or are remunerated by their provincial government for expanded services such as medications reviews (Medschecks in Ontario). In the United Kingdom, pharmacists who undertake additional training are obtaining prescribing rights and this is because of pharmacy education. They are also being paid for by the government for medicine use reviews. In Scotland the pharmacist can write prescriptions for Scottish registered patients of their regular medications, for the majority of drugs, except for controlled drugs, when the patient is unable to see their doctor, as could happen if they are away from home or the doctor is unavailable. In the United States, pharmaceutical care or clinical pharmacy has had an evolving influence on the practice of pharmacy. Moreover, the Doctor of Pharmacy (Pharm. D.) degree is now required before entering practice and some pharmacists now complete one or two years of residency or fellowship training following graduation. In addition, consultant pharmacists, who traditionally operated primarily in nursing homes are now expanding into direct consultation with patients, under the banner of "senior care pharmacy."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who can't pay Australian pharmacists for doing Home Medicines Reviews?


One theory is that, while disobedience may be helpful, any great amount of it would undermine the law by encouraging general disobedience which is neither conscientious nor of social benefit. Therefore, conscientious lawbreakers must be punished. Michael Bayles argues that if a person violates a law in order to create a test case as to the constitutionality of a law, and then wins his case, then that act did not constitute civil disobedience. It has also been argued that breaking the law for self-gratification, as in the case of a homosexual or cannabis user who does not direct his act at securing the repeal of amendment of the law, is not civil disobedience. Likewise, a protestor who attempts to escape punishment by committing the crime covertly and avoiding attribution, or by denying having committed the crime, or by fleeing the jurisdiction, is generally viewed as not being a civil disobedient.

Answer this question, if possible (if impossible, reply "unanswerable"): For what reason would someone avoid crimes while protesting?

In general, there are three sectors of construction: buildings, infrastructure and industrial. Building construction is usually further divided into residential and non-residential (commercial/institutional). Infrastructure is often called heavy/highway, heavy civil or heavy engineering. It includes large public works, dams, bridges, highways, water/wastewater and utility distribution. Industrial includes refineries, process chemical, power generation, mills and manufacturing plants. There are other ways to break the industry into sectors or markets.

What are buildings, stuctures and industrial?


Read this: Between Bingen and Bonn, the Middle Rhine flows through the Rhine Gorge, a formation which was created by erosion. The rate of erosion equaled the uplift in the region, such that the river was left at about its original level while the surrounding lands raised. The gorge is quite deep and is the stretch of the river which is known for its many castles and vineyards. It is a UNESCO World Heritage Site (2002) and known as "the Romantic Rhine", with more than 40 castles and fortresses from the Middle Ages and many quaint and lovely country villages.

Céloron's expedition force consisted of about 200 Troupes de la marine and 30 Indians. The expedition covered about 3,000 miles (4,800 km) between June and November 1749. It went up the St. Lawrence, continued along the northern shore of Lake Ontario, crossed the portage at Niagara, and followed the southern shore of Lake Erie. At the Chautauqua Portage (near present-day Barcelona, New York), the expedition moved inland to the Allegheny River, which it followed to the site of present-day Pittsburgh. There Céloron buried lead plates engraved with the French claim to the Ohio Country. Whenever he encountered British merchants or fur-traders, Céloron informed them of the French claims on the territory and told them to leave.

The new British command was not in place until July. When he arrived in Albany, Abercrombie refused to take any significant actions until Loudoun approved them. Montcalm took bold action against his inertia. Building on Vaudreuil's work harassing the Oswego garrison, Montcalm executed a strategic feint by moving his headquarters to Ticonderoga, as if to presage another attack along Lake George. With Abercrombie pinned down at Albany, Montcalm slipped away and led the successful attack on Oswego in August. In the aftermath, Montcalm and the Indians under his command disagreed about the disposition of prisoners' personal effects. The Europeans did not consider them prizes and prevented the Indians from stripping the prisoners of their valuables, which angered the Indians.
Try to answer this question if possible (otherwise reply "unanswerable"): What agreement did Montcalm and Indians have?

It is likely that a multicomponent, adaptive immune system arose with the first vertebrates, as invertebrates do not generate lymphocytes or an antibody-based humoral response. Many species, however, utilize mechanisms that appear to be precursors of these aspects of vertebrate immunity. Immune systems appear even in the structurally most simple forms of life, with bacteria using a unique defense mechanism, called the restriction modification system to protect themselves from viral pathogens, called bacteriophages. Prokaryotes also possess acquired immunity, through a system that uses CRISPR sequences to retain fragments of the genomes of phage that they have come into contact with in the past, which allows them to block virus replication through a form of RNA interference. Offensive elements of the immune systems are also present in unicellular eukaryotes, but studies of their roles in defense are few.

Invertebrates do not generate what type of cells that are a part of the vertebrate adaptive immune system?
