In response to American aid to Israel, on October 16, 1973, OPEC raised the posted price of oil by 70%, to $5.11 a barrel. The following day, oil ministers agreed to the embargo, a cut in production by five percent from September's output and to continue to cut production in five percent monthly increments until their economic and political objectives were met. On October 19, Nixon requested Congress to appropriate $2.2 billion in emergency aid to Israel, including $1.5 billion in outright grants. George Lenczowski notes, "Military supplies did not exhaust Nixon's eagerness to prevent Israel's collapse...This [$2.2 billion] decision triggered a collective OPEC response." Libya immediately announced it would embargo oil shipments to the United States. Saudi Arabia and the other Arab oil-producing states joined the embargo on October 20, 1973. At their Kuwait meeting, OAPEC proclaimed the embargo that curbed exports to various countries and blocked all oil deliveries to the US as a "principal hostile country".

Why did OPEC block oil deliveries to the United States?


People who climb mountains or fly in non-pressurized fixed-wing aircraft sometimes have supplemental O
2 supplies.[h] Passengers traveling in (pressurized) commercial airplanes have an emergency supply of O
2 automatically supplied to them in case of cabin depressurization. Sudden cabin pressure loss activates chemical oxygen generators above each seat, causing oxygen masks to drop. Pulling on the masks "to start the flow of oxygen" as cabin safety instructions dictate, forces iron filings into the sodium chlorate inside the canister. A steady stream of oxygen gas is then produced by the exothermic reaction.

Answer this question, if possible (if impossible, reply "unanswerable"): What gas does the airline exothermic reaction produce?

AUSTPAC was an Australian public X.25 network operated by Telstra. Started by Telecom Australia in the early 1980s, AUSTPAC was Australia's first public packet-switched data network, supporting applications such as on-line betting, financial applications — the Australian Tax Office made use of AUSTPAC — and remote terminal access to academic institutions, who maintained their connections to AUSTPAC up until the mid-late 1990s in some cases. Access can be via a dial-up terminal to a PAD, or, by linking a permanent X.25 node to the network.[citation needed]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How are AUSTPAC connections made


Normans:

One of the first Norman mercenaries to serve as a Byzantine general was Hervé in the 1050s. By then however, there were already Norman mercenaries serving as far away as Trebizond and Georgia. They were based at Malatya and Edessa, under the Byzantine duke of Antioch, Isaac Komnenos. In the 1060s, Robert Crispin led the Normans of Edessa against the Turks. Roussel de Bailleul even tried to carve out an independent state in Asia Minor with support from the local population, but he was stopped by the Byzantine general Alexius Komnenos.

Ctenophora:

Most species are hermaphrodites—a single animal can produce both eggs and sperm, meaning it can fertilize its own egg, not needing a mate. Some are simultaneous hermaphrodites, which can produce both eggs and sperm at the same time. Others are sequential hermaphrodites, in which the eggs and sperm mature at different times. Fertilization is generally external, although platyctenids' eggs are fertilized inside their parents' bodies and kept there until they hatch. The young are generally planktonic and in most species look like miniature cydippids, gradually changing into their adult shapes as they grow. The exceptions are the beroids, whose young are miniature beroids with large mouths and no tentacles, and the platyctenids, whose young live as cydippid-like plankton until they reach near-adult size, but then sink to the bottom and rapidly metamorphose into the adult form. In at least some species, juveniles are capable of reproduction before reaching the adult size and shape. The combination of hermaphroditism and early reproduction enables small populations to grow at an explosive rate.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". How quickly do plankton populations grow due to hermaphrodism and early reproduction?


The area is also known for its early twentieth century homes, many of which have been restored in recent decades. The area includes many California Bungalow and American Craftsman style homes, Spanish Colonial Revival Style architecture, Mediterranean Revival Style architecture, Mission Revival Style architecture, and many Storybook houses designed by Fresno architects, Hilliard, Taylor & Wheeler. The residential architecture of the Tower District contrasts with the newer areas of tract homes urban sprawl in north and east areas of Fresno.
Try to answer this question if possible (otherwise reply "unanswerable"): What area is the Tower District similar to in architecture?


Read this: The principle of inclusions and components states that, with sedimentary rocks, if inclusions (or clasts) are found in a formation, then the inclusions must be older than the formation that contains them. For example, in sedimentary rocks, it is common for gravel from an older formation to be ripped up and included in a newer layer. A similar situation with igneous rocks occurs when xenoliths are found. These foreign bodies are picked up as magma or lava flows, and are incorporated, later to cool in the matrix. As a result, xenoliths are older than the rock which contains them.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What is something that is often torn up and included in sedimentary rock?


During Reconstruction and the Gilded Age, Jacksonville and nearby St. Augustine became popular winter resorts for the rich and famous. Visitors arrived by steamboat and later by railroad. President Grover Cleveland attended the Sub-Tropical Exposition in the city on February 22, 1888 during his trip to Florida. This highlighted the visibility of the state as a worthy place for tourism. The city's tourism, however, was dealt major blows in the late 19th century by yellow fever outbreaks. In addition, extension of the Florida East Coast Railway further south drew visitors to other areas. From 1893 to 1938 Jacksonville was the site of the Florida Old Confederate Soldiers and Sailors Home with a nearby cemetery.

Answer this question, if possible (if impossible, reply "unanswerable"): During what age was Jacksonville no longer a popular destination for the rich?


There were two kinds of X.25 networks. Some such as DATAPAC and TRANSPAC were initially implemented with an X.25 external interface. Some older networks such as TELENET and TYMNET were modified to provide a X.25 host interface in addition to older host connection schemes. DATAPAC was developed by Bell Northern Research which was a joint venture of Bell Canada (a common carrier) and Northern Telecom (a telecommunications equipment supplier). Northern Telecom sold several DATAPAC clones to foreign PTTs including the Deutsche Bundespost. X.75 and X.121 allowed the interconnection of national X.25 networks. A user or host could call a host on a foreign network by including the DNIC of the remote network as part of the destination address.[citation needed]

Prime number:

In addition to the Riemann hypothesis, many more conjectures revolving about primes have been posed. Often having an elementary formulation, many of these conjectures have withstood a proof for decades: all four of Landau's problems from 1912 are still unsolved. One of them is Goldbach's conjecture, which asserts that every even integer n greater than 2 can be written as a sum of two primes. As of February 2011[update], this conjecture has been verified for all numbers up to n = 2 · 1017. Weaker statements than this have been proven, for example Vinogradov's theorem says that every sufficiently large odd integer can be written as a sum of three primes. Chen's theorem says that every sufficiently large even number can be expressed as the sum of a prime and a semiprime, the product of two primes. Also, any even integer can be written as the sum of six primes. The branch of number theory studying such questions is called additive number theory.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Which theorem states that every large even integer can be written as a prime summed with a semiprime?

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.

What is the center library in the Harvard library system?


Like much of the south Atlantic region of the United States, Jacksonville has a humid subtropical climate (Köppen Cfa), with mild weather during winters and hot and humid weather during summers. Seasonal rainfall is concentrated in the warmest months from May through September, while the driest months are from November through April. Due to Jacksonville's low latitude and coastal location, the city sees very little cold weather, and winters are typically mild and sunny. Summers can be hot and wet, and summer thunderstorms with torrential but brief downpours are common.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): High altitude as well as what contributes to Jacksonville's lack of cold-weather question work

BSkyB's direct-to-home satellite service became available in 10 million homes in 2010, Europe's first pay-TV platform in to achieve that milestone. Confirming it had reached its target, the broadcaster said its reach into 36% of households in the UK represented an audience of more than 25m people. The target was first announced in August 2004, since then an additional 2.4m customers had subscribed to BSkyB's direct-to-home service. Media commentators had debated whether the figure could be reached as the growth in subscriber numbers elsewhere in Europe flattened.

What free TV platform was most popular in Europe at this time?


Read this: On 1 February 2007, the eve of the publication of IPCC's major report on climate, a study was published suggesting that temperatures and sea levels have been rising at or above the maximum rates proposed during the last IPCC report in 2001. The study compared IPCC 2001 projections on temperature and sea level change with observations. Over the six years studied, the actual temperature rise was near the top end of the range given by IPCC's 2001 projection, and the actual sea level rise was above the top of the range of the IPCC projection.

How did the 2001 IPCC report compare to reality for 2001-2006?

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.

Inter-network routing was what kind of system?

The further decline of Byzantine state-of-affairs paved the road to a third attack in 1185, when a large Norman army invaded Dyrrachium, owing to the betrayal of high Byzantine officials. Some time later, Dyrrachium—one of the most important naval bases of the Adriatic—fell again to Byzantine hands.

Southern California:

Los Angeles (at 3.7 million people) and San Diego (at 1.3 million people), both in southern California, are the two largest cities in all of California (and two of the eight largest cities in the United States). In southern California there are also twelve cities with more than 200,000 residents and 34 cities over 100,000 in population. Many of southern California's most developed cities lie along or in close proximity to the coast, with the exception of San Bernardino and Riverside.

Read this: Southern California, often abbreviated SoCal, is a geographic and cultural region that generally comprises California's southernmost 10 counties. The region is traditionally described as "eight counties", based on demographics and economic ties: Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura. The more extensive 10-county definition, including Kern and San Luis Obispo counties, is also used based on historical political divisions. Southern California is a major economic center for the state of California and the United States.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Despite being traditionall described as "eight counties", how many counties does this region actually have?


In the first half of the 17th century, a plague claimed some 1.7 million victims in Italy, or about 14% of the population. In 1656, the plague killed about half of Naples' 300,000 inhabitants. More than 1.25 million deaths resulted from the extreme incidence of plague in 17th-century Spain. The plague of 1649 probably reduced the population of Seville by half. In 1709–13, a plague epidemic that followed the Great Northern War (1700–21, Sweden v. Russia and allies) killed about 100,000 in Sweden, and 300,000 in Prussia. The plague killed two-thirds of the inhabitants of Helsinki, and claimed a third of Stockholm's population. Europe's last major epidemic occurred in 1720 in Marseille.
Try to answer this question if possible (otherwise reply "unanswerable"): In what country is Marseille?


Closely related fields in theoretical computer science are analysis of algorithms and computability theory. A key distinction between analysis of algorithms and computational complexity theory is that the former is devoted to analyzing the amount of resources needed by a particular algorithm to solve a problem, whereas the latter asks a more general question about all possible algorithms that could be used to solve the same problem. More precisely, it tries to classify problems that can or cannot be solved with appropriately restricted resources. In turn, imposing restrictions on the available resources is what distinguishes computational complexity from computability theory: the latter theory asks what kind of problems can, in principle, be solved algorithmically.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What two fields of theoretical computer science closely mirror computational complexity theory?

Although the European Union does not have a codified constitution, like every political body it has laws which "constitute" its basic governance structure. The EU's primary constitutional sources are the Treaty on European Union (TEU) and the Treaty on the Functioning of the European Union (TFEU), which have been agreed or adhered to among the governments of all 28 member states. The Treaties establish the EU's institutions, list their powers and responsibilities, and explain the areas in which the EU can legislate with Directives or Regulations. The European Commission has the initiative to propose legislation. During the ordinary legislative procedure, the Council (which are ministers from member state governments) and the European Parliament (elected by citizens) can make amendments and must give their consent for laws to pass. The Commission oversees departments and various agencies that execute or enforce EU law. The "European Council" (rather than the Council, made up of different government Ministers) is composed of the Prime Ministers or executive Presidents of the member states. It appoints the Commissioners and the board of the European Central Bank. The European Court of Justice is the supreme judicial body which interprets EU law, and develops it through precedent. The Court can review the legality of the EU institutions' actions, in compliance with the Treaties. It can also decide upon claims for breach of EU laws from member states and citizens.

What governing body appoints commissioners and the board of European Central Bank?


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.

How many more flows carry insignificant amounts of water?

In addition to the negative consequences of sleep deprivation, sleep and the intertwined circadian system have been shown to have strong regulatory effects on immunological functions affecting both the innate and the adaptive immunity. First, during the early slow-wave-sleep stage, a sudden drop in blood levels of cortisol, epinephrine, and norepinephrine induce increased blood levels of the hormones leptin, pituitary growth hormone, and prolactin. These signals induce a pro-inflammatory state through the production of the pro-inflammatory cytokines interleukin-1, interleukin-12, TNF-alpha and IFN-gamma. These cytokines then stimulate immune functions such as immune cells activation, proliferation, and differentiation. It is during this time that undifferentiated, or less differentiated, like naïve and central memory T cells, peak (i.e. during a time of a slowly evolving adaptive immune response). In addition to these effects, the milieu of hormones produced at this time (leptin, pituitary growth hormone, and prolactin) support the interactions between APCs and T-cells, a shift of the Th1/Th2 cytokine balance towards one that supports Th1, an increase in overall Th cell proliferation, and naïve T cell migration to lymph nodes. This milieu is also thought to support the formation of long-lasting immune memory through the initiation of Th1 immune responses.

Answer this question, if possible (if impossible, reply "unanswerable"): Hormones released during sleep support the interaction of T-cells and what species?

The 1973 oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries (OAPEC, consisting of the Arab members of OPEC plus Egypt and Syria) proclaimed an oil embargo. By the end of the embargo in March 1974, the price of oil had risen from US$3 per barrel to nearly $12 globally; US prices were significantly higher. The embargo caused an oil crisis, or "shock", with many short- and long-term effects on global politics and the global economy. It was later called the "first oil shock", followed by the 1979 oil crisis, termed the "second oil shock."

When was the second oil crisis?


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.

The principle of faunal succession is based on the appearance of fossils in sedimentary rocks. As organisms exist at the same time period throughout the world, their presence or (sometimes) absence may be used to provide a relative age of the formations in which they are found. Based on principles laid out by William Smith almost a hundred years before the publication of Charles Darwin's theory of evolution, the principles of succession were developed independently of evolutionary thought. The principle becomes quite complex, however, given the uncertainties of fossilization, the localization of fossil types due to lateral changes in habitat (facies change in sedimentary strata), and that not all fossils may be found globally at the same time.

What is the theory of evolution based on?


Originating as the Jama'at al-Tawhid wal-Jihad in 1999, it pledged allegiance to al-Qaeda in 2004, participated in the Iraqi insurgency that followed the March 2003 invasion of Iraq by Western forces, joined the fight in the Syrian Civil War beginning in March 2011, and was expelled from al-Qaeda in early 2014, (which complained of its failure to consult and "notorious intransigence"). The group gained prominence after it drove Iraqi government forces out of key cities in western Iraq in a 2014 offensive. The group is adept at social media, posting Internet videos of beheadings of soldiers, civilians, journalists and aid workers, and is known for its destruction of cultural heritage sites. The United Nations has held ISIL responsible for human rights abuses and war crimes, and Amnesty International has reported ethnic cleansing by the group on a "historic scale". The group has been designated a terrorist organisation by the United Nations, the European Union and member states, the United States, India, Indonesia, Turkey, Saudi Arabia, Syria and other countries.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"):  What has the United Nations not claimed ISIL to be?


Fourth, national courts have a duty to interpret domestic law "as far as possible in the light of the wording and purpose of the directive". Textbooks (though not the Court itself) often called this "indirect effect". In Marleasing SA v La Comercial SA the Court of Justice held that a Spanish Court had to interpret its general Civil Code provisions, on contracts lacking cause or defrauding creditors, to conform with the First Company Law Directive article 11, that required incorporations would only be nullified for a fixed list of reasons. The Court of Justice quickly acknowledged that the duty of interpretation cannot contradict plain words in a national statute. But, fifth, if a member state has failed to implement a Directive, a citizen may not be able to bring claims against other non-state parties, but can sue the member state itself for failure to implement the law. So, in Francovich v Italy, the Italian government had failed to set up an insurance fund for employees to claim unpaid wages if their employers had gone insolvent, as the Insolvency Protection Directive required. Francovich, the former employee of a bankrupt Venetian firm, was therefore allowed to claim 6 million Lira from the Italian government in damages for his loss. The Court of Justice held that if a Directive would confer identifiable rights on individuals, and there is a causal link between a member state's violation of EU and a claimant's loss, damages must be paid. The fact that the incompatible law is an Act of Parliament is no defence.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the Italian government fail to do in Francovich v Italy?

Many of the same decisions and principles that apply in other criminal investigations and arrests arise also in civil disobedience cases. For example, the suspect may need to decide whether or not to grant a consent search of his property, and whether or not to talk to police officers. It is generally agreed within the legal community, and is often believed within the activist community, that a suspect's talking to criminal investigators can serve no useful purpose, and may be harmful. However, some civil disobedients have nonetheless found it hard to resist responding to investigators' questions, sometimes due to a lack of understanding of the legal ramifications, or due to a fear of seeming rude. Also, some civil disobedients seek to use the arrest as an opportunity to make an impression on the officers. Thoreau wrote, "My civil neighbor, the tax-gatherer, is the very man I have to deal with--for it is, after all, with men and not with parchment that I quarrel--and he has voluntarily chosen to be an agent of the government. How shall he ever know well that he is and does as an officer of the government, or as a man, until he is obliged to consider whether he will treat me, his neighbor, for whom he has respect, as a neighbor and well-disposed man, or as a maniac and disturber of the peace, and see if he can get over this obstruction to his neighborliness without a ruder and more impetuous thought or speech corresponding with his action."

What reasons cause failure of the disobedience with authorities?


There are 13 natural reserves in Warsaw – among others, Bielany Forest, Kabaty Woods, Czerniaków Lake. About 15 kilometres (9 miles) from Warsaw, the Vistula river's environment changes strikingly and features a perfectly preserved ecosystem, with a habitat of animals that includes the otter, beaver and hundreds of bird species. There are also several lakes in Warsaw – mainly the oxbow lakes, like Czerniaków Lake, the lakes in the Łazienki or Wilanów Parks, Kamionek Lake. There are lot of small lakes in the parks, but only a few are permanent – the majority are emptied before winter to clean them of plants and sediments.

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.

The secondary level includes schools offering years 7 through 12 (year twelve is known as lower sixth) and year 13 (upper sixth). This category includes university-preparatory schools or "prep schools", boarding schools and day schools. Tuition at private secondary schools varies from school to school and depends on many factors, including the location of the school, the willingness of parents to pay, peer tuitions and the school's financial endowment. High tuition, schools claim, is used to pay higher salaries for the best teachers and also used to provide enriched learning environments, including a low student to teacher ratio, small class sizes and services, such as libraries, science laboratories and computers. Some private schools are boarding schools and many military academies are privately owned or operated as well.

Oxygen:

By the late 19th century scientists realized that air could be liquefied, and its components isolated, by compressing and cooling it. Using a cascade method, Swiss chemist and physicist Raoul Pierre Pictet evaporated liquid sulfur dioxide in order to liquefy carbon dioxide, which in turn was evaporated to cool oxygen gas enough to liquefy it. He sent a telegram on December 22, 1877 to the French Academy of Sciences in Paris announcing his discovery of liquid oxygen. Just two days later, French physicist Louis Paul Cailletet announced his own method of liquefying molecular oxygen. Only a few drops of the liquid were produced in either case so no meaningful analysis could be conducted. Oxygen was liquified in stable state for the first time on March 29, 1883 by Polish scientists from Jagiellonian University, Zygmunt Wróblewski and Karol Olszewski.

Warsaw's mixture of architectural styles reflects the turbulent history of the city and country. During the Second World War, Warsaw was razed to the ground by bombing raids and planned destruction. After liberation, rebuilding began as in other cities of the communist-ruled PRL. Most of the historical buildings were thoroughly reconstructed. However, some of the buildings from the 19th century that had been preserved in reasonably reconstructible form were nonetheless eradicated in the 1950s and 1960s (e.g. Leopold Kronenberg Palace). Mass residential blocks were erected, with basic design typical of Eastern bloc countries.

Deforestation is the conversion of forested areas to non-forested areas. The main sources of deforestation in the Amazon are human settlement and development of the land. Prior to the early 1960s, access to the forest's interior was highly restricted, and the forest remained basically intact. Farms established during the 1960s were based on crop cultivation and the slash and burn method. However, the colonists were unable to manage their fields and the crops because of the loss of soil fertility and weed invasion. The soils in the Amazon are productive for just a short period of time, so farmers are constantly moving to new areas and clearing more land. These farming practices led to deforestation and caused extensive environmental damage. Deforestation is considerable, and areas cleared of forest are visible to the naked eye from outer space.

Read this: Following the treaty, King George III issued the Royal Proclamation of 1763 on October 7, 1763, which outlined the division and administration of the newly conquered territory, and to some extent continues to govern relations between the government of modern Canada and the First Nations. Included in its provisions was the reservation of lands west of the Appalachian Mountains to its Indian population, a demarcation that was at best a temporary impediment to a rising tide of westward-bound settlers. The proclamation also contained provisions that prevented civic participation by the Roman Catholic Canadians. When accommodations were made in the Quebec Act in 1774 to address this and other issues, religious concerns were raised in the largely Protestant Thirteen Colonies over the advance of "popery"; the Act maintained French Civil law, including the seigneurial system, a medieval code soon to be removed from France within a generation by the French Revolution.

Long-term active memory is acquired following infection by activation of B and T cells. Active immunity can also be generated artificially, through vaccination. The principle behind vaccination (also called immunization) is to introduce an antigen from a pathogen in order to stimulate the immune system and develop specific immunity against that particular pathogen without causing disease associated with that organism. This deliberate induction of an immune response is successful because it exploits the natural specificity of the immune system, as well as its inducibility. With infectious disease remaining one of the leading causes of death in the human population, vaccination represents the most effective manipulation of the immune system mankind has developed.

Answer this question, if possible (if impossible, reply "unanswerable"): What does vaccination not exploit?


Read this: In anglophone academic works, theories regarding imperialism are often based on the British experience. The term "Imperialism" was originally introduced into English in its present sense in the late 1870s by opponents of the allegedly aggressive and ostentatious imperial policies of British prime Minister Benjamin Disraeli. It was shortly appropriated by supporters of "imperialism" such as Joseph Chamberlain. For some, imperialism designated a policy of idealism and philanthropy; others alleged that it was characterized by political self-interest, and a growing number associated it with capitalist greed. Liberal John A. Hobson and Marxist Vladimir Lenin added a more theoretical macroeconomic connotation to the term. Lenin in particular exerted substantial influence over later Marxist conceptions of imperialism with his work Imperialism, the Highest Stage of Capitalism. In his writings Lenin portrayed Imperialism as a natural extension of capitalism that arose from need for capitalist economies to constantly expand investment, material resources and manpower in such a way that necessitated colonial expansion. This conception of imperialism as a structural feature of capitalism is echoed by later Marxist theoreticians. Many theoreticians on the left have followed in emphasizing the structural or systemic character of "imperialism". Such writers have expanded the time period associated with the term so that it now designates neither a policy, nor a short space of decades in the late 19th century, but a world system extending over a period of centuries, often going back to Christopher Columbus and, in some accounts, to the Crusades. As the application of the term has expanded, its meaning has shifted along five distinct but often parallel axes: the moral, the economic, the systemic, the cultural, and the temporal. Those changes reflect - among other shifts in sensibility - a growing unease, even squeamishness, with the fact of power, specifically, Western power.

 According to Lenin why must capitalistic countries not have an imperialistic policy?

European Union law:

The European Commission is the main executive body of the European Union. Article 17(1) of the Treaty on European Union states the Commission should "promote the general interest of the Union" while Article 17(3) adds that Commissioners should be "completely independent" and not "take instructions from any Government". Under article 17(2), "Union legislative acts may only be adopted on the basis of a Commission proposal, except where the Treaties provide otherwise." This means that the Commission has a monopoly on initiating the legislative procedure, although the Council is the "de facto catalyst of many legislative initiatives". The Parliament can also formally request the Commission to submit a legislative proposal but the Commission can reject such a suggestion, giving reasons. The Commission's President (currently an ex-Luxembourg Prime Minister, Jean-Claude Juncker) sets the agenda for the EU's work. Decisions are taken by a simple majority vote, usually through a "written procedure" of circulating the proposals and adopting if there are no objections.[citation needed] Since Ireland refused to consent to changes in the Treaty of Lisbon 2007, there remains one Commissioner for each of the 28 member states, including the President and the High Representative for Foreign and Security Policy (currently Federica Mogherini). The Commissioners (and most importantly, the portfolios they will hold) are bargained over intensively by the member states. The Commissioners, as a block, are then subject to a qualified majority vote of the Council to approve, and majority approval of the Parliament. The proposal to make the Commissioners be drawn from the elected Parliament, was not adopted in the Treaty of Lisbon. This means Commissioners are, through the appointment process, the unelected subordinates of member state governments.

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".

Read this: After Malaysia's independence in 1957, the government instructed all schools to surrender their properties and be assimilated into the National School system. This caused an uproar among the Chinese and a compromise was achieved in that the schools would instead become "National Type" schools. Under such a system, the government is only in charge of the school curriculum and teaching personnel while the lands still belonged to the schools. While Chinese primary schools were allowed to retain Chinese as the medium of instruction, Chinese secondary schools are required to change into English-medium schools. Over 60 schools converted to become National Type schools.

A regulation of the Rhine was called for, with an upper canal near Diepoldsau and a lower canal at Fußach, in order to counteract the constant flooding and strong sedimentation in the western Rhine Delta. The Dornbirner Ach had to be diverted, too, and it now flows parallel to the canalized Rhine into the lake. Its water has a darker color than the Rhine; the latter's lighter suspended load comes from higher up the mountains. It is expected that the continuous input of sediment into the lake will silt up the lake. This has already happened to the former Lake Tuggenersee.

Subject Committees are established at the beginning of each parliamentary session, and again the members on each committee reflect the balance of parties across Parliament. Typically each committee corresponds with one (or more) of the departments (or ministries) of the Scottish Government. The current Subject Committees in the fourth Session are: Economy, Energy and Tourism; Education and Culture; Health and Sport; Justice; Local Government and Regeneration; Rural Affairs, Climate Change and Environment; Welfare Reform; and Infrastructure and Capital Investment.

It is recognised that an epidemiological account of the plague is as important as an identification of symptoms, but researchers are hampered by the lack of reliable statistics from this period. Most work has been done on the spread of the plague in England, and even estimates of overall population at the start vary by over 100% as no census was undertaken between the time of publication of the Domesday Book and the year 1377. Estimates of plague victims are usually extrapolated from figures from the clergy.

Another factor in the early 1990s that worked to radicalize the Islamist movement was the Gulf War, which brought several hundred thousand US and allied non-Muslim military personnel to Saudi Arabian soil to put an end to Saddam Hussein's occupation of Kuwait. Prior to 1990 Saudi Arabia played an important role in restraining the many Islamist groups that received its aid. But when Saddam, secularist and Ba'athist dictator of neighboring Iraq, attacked Saudi Arabia (his enemy in the war), western troops came to protect the Saudi monarchy. Islamists accused the Saudi regime of being a puppet of the west.

Up until 1990, Saudi Arabia played an unimportant role in restraining what groups?


Older than The Game by 23 years, the Harvard-Yale Regatta was the original source of the athletic rivalry between the two schools. It is held annually in June on the Thames River in eastern Connecticut. The Harvard crew is typically considered to be one of the top teams in the country in rowing. Today, Harvard fields top teams in several other sports, such as the Harvard Crimson men's ice hockey team (with a strong rivalry against Cornell), squash, and even recently won NCAA titles in Men's and Women's Fencing. Harvard also won the Intercollegiate Sailing Association National Championships in 2003.

Answer this question, if possible (if impossible, reply "unanswerable"): In what body of water is the Harvard - Yale Regatta held?


The mechanisms used to evade the adaptive immune system are more complicated. The simplest approach is to rapidly change non-essential epitopes (amino acids and/or sugars) on the surface of the pathogen, while keeping essential epitopes concealed. This is called antigenic variation. An example is HIV, which mutates rapidly, so the proteins on its viral envelope that are essential for entry into its host target cell are constantly changing. These frequent changes in antigens may explain the failures of vaccines directed at this virus. The parasite Trypanosoma brucei uses a similar strategy, constantly switching one type of surface protein for another, allowing it to stay one step ahead of the antibody response. Masking antigens with host molecules is another common strategy for avoiding detection by the immune system. In HIV, the envelope that covers the virion is formed from the outermost membrane of the host cell; such "self-cloaked" viruses make it difficult for the immune system to identify them as "non-self" structures.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What compounds can be masked with the molecules of the host cell in order for a virus to evade detection?


Read this: While the Treaties and Regulations will have direct effect (if clear, unconditional and immediate), Directives do not generally give citizens (as opposed to the member state) standing to sue other citizens. In theory, this is because TFEU article 288 says Directives are addressed to the member states and usually "leave to the national authorities the choice of form and methods" to implement. In part this reflects that directives often create minimum standards, leaving member states to apply higher standards. For example, the Working Time Directive requires that every worker has at least 4 weeks paid holidays each year, but most member states require more than 28 days in national law. However, on the current position adopted by the Court of Justice, citizens have standing to make claims based on national laws that implement Directives, but not from Directives themselves. Directives do not have so called "horizontal" direct effect (i.e. between non-state parties). This view was instantly controversial, and in the early 1990s three Advocate Generals persuasively argued that Directives should create rights and duties for all citizens. The Court of Justice refused, but there are five large exceptions.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What generally does not allow citizens to sue other citizens?


From the Eocene onwards, the ongoing Alpine orogeny caused a N–S rift system to develop in this zone. The main elements of this rift are the Upper Rhine Graben, in southwest Germany and eastern France and the Lower Rhine Embayment, in northwest Germany and the southeastern Netherlands. By the time of the Miocene, a river system had developed in the Upper Rhine Graben, that continued northward and is considered the first Rhine river. At that time, it did not yet carry discharge from the Alps; instead, the watersheds of the Rhone and Danube drained the northern flanks of the Alps.
Try to answer this question if possible (otherwise reply "unanswerable"): What did the ongoing Alpine orogeny cause before the Eocene?


The complexity class P is often seen as a mathematical abstraction modeling those computational tasks that admit an efficient algorithm. This hypothesis is called the Cobham–Edmonds thesis. The complexity class NP, on the other hand, contains many problems that people would like to solve efficiently, but for which no efficient algorithm is known, such as the Boolean satisfiability problem, the Hamiltonian path problem and the vertex cover problem. Since deterministic Turing machines are special non-deterministic Turing machines, it is easily observed that each problem in P is also member of the class NP.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): In what theoretical machine is it confirmed that a problem in P belies membership in the NP class?


Ersatzschulen are ordinary primary or secondary schools, which are run by private individuals, private organizations or religious groups. These schools offer the same types of diplomas as public schools. Ersatzschulen lack the freedom to operate completely outside of government regulation. Teachers at Ersatzschulen must have at least the same education and at least the same wages as teachers at public schools, an Ersatzschule must have at least the same academic standards as a public school and Article 7, Paragraph 4 of the Grundgesetz, also forbids segregation of pupils according to the means of their parents (the so-called Sonderungsverbot). Therefore, most Ersatzschulen have very low tuition fees and/or offer scholarships, compared to most other Western European countries. However, it is not possible to finance these schools with such low tuition fees, which is why all German Ersatzschulen are additionally financed with public funds. The percentages of public money could reach 100% of the personnel expenditures. Nevertheless, Private Schools became insolvent in the past in Germany.

Steam engine:

Other components are often present; pumps (such as an injector) to supply water to the boiler during operation, condensers to recirculate the water and recover the latent heat of vaporisation, and superheaters to raise the temperature of the steam above its saturated vapour point, and various mechanisms to increase the draft for fireboxes. When coal is used, a chain or screw stoking mechanism and its drive engine or motor may be included to move the fuel from a supply bin (bunker) to the firebox. See: Mechanical stoker

Read this: The U.S. government has engaged in efforts to counter Islamism, or violent Islamism, since 2001. These efforts were centred in the U.S. around public diplomacy programmes conducted by the State Department. There have been calls to create an independent agency in the U.S. with a specific mission of undermining Islamism and jihadism. Christian Whiton, an official in the George W. Bush administration, called for a new agency focused on the nonviolent practice of "political warfare" aimed at undermining the ideology. U.S. Defense Secretary Robert Gates called for establishing something similar to the defunct U.S. Information Agency, which was charged with undermining the communist ideology during the Cold War.

The correlation between capitalism, aristocracy, and imperialism has long been debated among historians and political theorists. Much of the debate was pioneered by such theorists as J. A. Hobson (1858–1940), Joseph Schumpeter (1883–1950), Thorstein Veblen (1857–1929), and Norman Angell (1872–1967). While these non-Marxist writers were at their most prolific before World War I, they remained active in the interwar years. Their combined work informed the study of imperialism and it's impact on Europe, as well as contributed to reflections on the rise of the military-political complex in the United States from the 1950s. Hobson argued that domestic social reforms could cure the international disease of imperialism by removing its economic foundation. Hobson theorized that state intervention through taxation could boost broader consumption, create wealth, and encourage a peaceful, tolerant, multipolar world order.

 How did Hobson argue to not rid the world of imperialism?


Rhine:

Germanic tribes crossed the Rhine in the Migration period, by the 5th century establishing the kingdoms of Francia on the Lower Rhine, Burgundy on the Upper Rhine and Alemannia on the High Rhine. This "Germanic Heroic Age" is reflected in medieval legend, such as the Nibelungenlied which tells of the hero Siegfried killing a dragon on the Drachenfels (Siebengebirge) ("dragons rock"), near Bonn at the Rhine and of the Burgundians and their court at Worms, at the Rhine and Kriemhild's golden treasure, which was thrown into the Rhine by Hagen.

Read this: Like sponges and cnidarians, ctenophores have two main layers of cells that sandwich a middle layer of jelly-like material, which is called the mesoglea in cnidarians and ctenophores; more complex animals have three main cell layers and no intermediate jelly-like layer. Hence ctenophores and cnidarians have traditionally been labelled diploblastic, along with sponges. Both ctenophores and cnidarians have a type of muscle that, in more complex animals, arises from the middle cell layer, and as a result some recent text books classify ctenophores as triploblastic, while others still regard them as diploblastic.

Steven Barkan writes that if defendants plead not guilty, "they must decide whether their primary goal will be to win an acquittal and avoid imprisonment or a fine, or to use the proceedings as a forum to inform the jury and the public of the political circumstances surrounding the case and their reasons for breaking the law via civil disobedience." A technical defense may enhance the chances for acquittal but make for more boring proceedings and reduced press coverage. During the Vietnam War era, the Chicago Eight used a political defense, while Benjamin Spock used a technical defense. In countries such as the United States whose laws guarantee the right to a jury trial but do not excuse lawbreaking for political purposes, some civil disobedients seek jury nullification. Over the years, this has been made more difficult by court decisions such as Sparf v. United States, which held that the judge need not inform jurors of their nullification prerogative, and United States v. Dougherty, which held that the judge need not allow defendants to openly seek jury nullification.

For a long time, number theory in general, and the study of prime numbers in particular, was seen as the canonical example of pure mathematics, with no applications outside of the self-interest of studying the topic with the exception of use of prime numbered gear teeth to distribute wear evenly. In particular, number theorists such as British mathematician G. H. Hardy prided themselves on doing work that had absolutely no military significance. However, this vision was shattered in the 1970s, when it was publicly announced that prime numbers could be used as the basis for the creation of public key cryptography algorithms. Prime numbers are also used for hash tables and pseudorandom number generators.

ARPANET and SITA HLN became operational in 1969. Before the introduction of X.25 in 1973, about twenty different network technologies had been developed. Two fundamental differences involved the division of functions and tasks between the hosts at the edge of the network and the network core. In the datagram system, the hosts have the responsibility to ensure orderly delivery of packets. The User Datagram Protocol (UDP) is an example of a datagram protocol. In the virtual call system, the network guarantees sequenced delivery of data to the host. This results in a simpler host interface with less functionality than in the datagram model. The X.25 protocol suite uses this network type.

What type of network does SITA HLN not use?


The hydrography of the current delta is characterized by the delta's main arms, disconnected arms (Hollandse IJssel, Linge, Vecht, etc.) and smaller rivers and streams. Many rivers have been closed ("dammed") and now serve as drainage channels for the numerous polders. The construction of Delta Works changed the Delta in the second half of the 20th Century fundamentally. Currently Rhine water runs into the sea, or into former marine bays now separated from the sea, in five places, namely at the mouths of the Nieuwe Merwede, Nieuwe Waterway (Nieuwe Maas), Dordtse Kil, Spui and IJssel.

The earliest recorded incidents of collective civil disobedience took place during the Roman Empire[citation needed]. Unarmed Jews gathered in the streets to prevent the installation of pagan images in the Temple in Jerusalem.[citation needed][original research?] In modern times, some activists who commit civil disobedience as a group collectively refuse to sign bail until certain demands are met, such as favorable bail conditions, or the release of all the activists. This is a form of jail solidarity.[page needed] There have also been many instances of solitary civil disobedience, such as that committed by Thoreau, but these sometimes go unnoticed. Thoreau, at the time of his arrest, was not yet a well-known author, and his arrest was not covered in any newspapers in the days, weeks and months after it happened. The tax collector who arrested him rose to higher political office, and Thoreau's essay was not published until after the end of the Mexican War.

The war was fought primarily along the frontiers between New France and the British colonies, from Virginia in the South to Nova Scotia in the North. It began with a dispute over control of the confluence of the Allegheny and Monongahela rivers, called the Forks of the Ohio, and the site of the French Fort Duquesne and present-day Pittsburgh, Pennsylvania. The dispute erupted into violence in the Battle of Jumonville Glen in May 1754, during which Virginia militiamen under the command of 22-year-old George Washington ambushed a French patrol.

Genghis Khan united the Mongol and Turkic tribes of the steppes and became Great Khan in 1206. He and his successors expanded the Mongol empire across Asia. Under the reign of Genghis' third son, Ögedei Khan, the Mongols destroyed the weakened Jin dynasty in 1234, conquering most of northern China. Ögedei offered his nephew Kublai a position in Xingzhou, Hebei. Kublai was unable to read Chinese but had several Han Chinese teachers attached to him since his early years by his mother Sorghaghtani. He sought the counsel of Chinese Buddhist and Confucian advisers. Möngke Khan succeeded Ögedei's son, Güyük, as Great Khan in 1251. He granted his brother Kublai control over Mongol held territories in China. Kublai built schools for Confucian scholars, issued paper money, revived Chinese rituals, and endorsed policies that stimulated agricultural and commercial growth. He adopted as his capital city Kaiping in Inner Mongolia, later renamed Shangdu.

After al-Nimeiry was overthrown in 1985 the party did poorly in national elections, but in 1989 it was able to overthrow the elected post-al-Nimeiry government with the help of the military. Turabi was noted for proclaiming his support for the democratic process and a liberal government before coming to power, but strict application of sharia law, torture and mass imprisonment of the opposition, and an intensification of the long-running war in southern Sudan, once in power. The NIF regime also harbored Osama bin Laden for a time (before 9/11), and worked to unify Islamist opposition to the American attack on Iraq in the 1991 Gulf War.

Read this: Some civil disobedience defendants choose to make a defiant speech, or a speech explaining their actions, in allocution. In U.S. v. Burgos-Andujar, a defendant who was involved in a movement to stop military exercises by trespassing on U.S. Navy property argued to the court in allocution that "the ones who are violating the greater law are the members of the Navy". As a result, the judge increased her sentence from 40 to 60 days. This action was upheld because, according to the U.S. Court of Appeals for the First Circuit, her statement suggested a lack of remorse, an attempt to avoid responsibility for her actions, and even a likelihood of repeating her illegal actions. Some of the other allocution speeches given by the protesters complained about mistreatment from government officials.

In 2012 the Economist Intelligence Unit ranked Warsaw as the 32nd most liveable city in the world. It was also ranked as one of the most liveable cities in Central Europe. Today Warsaw is considered an "Alpha–" global city, a major international tourist destination and a significant cultural, political and economic hub. Warsaw's economy, by a wide variety of industries, is characterised by FMCG manufacturing, metal processing, steel and electronic manufacturing and food processing. The city is a significant centre of research and development, BPO, ITO, as well as of the Polish media industry. The Warsaw Stock Exchange is one of the largest and most important in Central and Eastern Europe. Frontex, the European Union agency for external border security, has its headquarters in Warsaw. It has been said that Warsaw, together with Frankfurt, London, Paris and Barcelona is one of the cities with the highest number of skyscrapers in the European Union.

Near Tamins-Reichenau the Anterior Rhine and the Posterior Rhine join and form the Rhine. The river makes a distinctive turn to the north near Chur. This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial alpine valley known as the Rhine Valley (German: Rheintal). Near Sargans a natural dam, only a few metres high, prevents it from flowing into the open Seeztal valley and then through Lake Walen and Lake Zurich into the river Aare. The Alpine Rhine begins in the most western part of the Swiss canton of Graubünden, and later forms the border between Switzerland to the West and Liechtenstein and later Austria to the East.

Citizenship of the EU has increasingly been seen as a "fundamental" status of member state nationals by the Court of Justice, and has accordingly increased the number of social services that people can access wherever they move. The Court has required that higher education, along with other forms of vocational training, should be more access, albeit with qualifying periods. In Commission v Austria the Court held that Austria was not entitled to restrict places in Austrian universities to Austrian students to avoid "structural, staffing and financial problems" if (mainly German) foreign students applied for places because there was little evidence of an actual problem.

Read this: The centrifugal governor was adopted by James Watt for use on a steam engine in 1788 after Watt’s partner Boulton saw one at a flour mill Boulton & Watt were building. The governor could not actually hold a set speed, because it would assume a new constant speed in response to load changes. The governor was able to handle smaller variations such as those caused by fluctuating heat load to the boiler. Also, there was a tendency for oscillation whenever there was a speed change. As a consequence, engines equipped only with this governor were not suitable for operations requiring constant speed, such as cotton spinning. The governor was improved over time and coupled with variable steam cut off, good speed control in response to changes in load was attainable near the end of the 19th century.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What did Watt add to the steam engine in 1788?


Read this: Shi Tianze was a Han Chinese who lived in the Jin dynasty. Interethnic marriage between Han and Jurchen became common at this time. His father was Shi Bingzhi (史秉直, Shih Ping-chih). Shi Bingzhi was married to a Jurchen woman (surname Na-ho) and a Han Chinese woman (surname Chang); it is unknown which of them was Shi Tianze's mother. Shi Tianze was married to two Jurchen women, a Han Chinese woman, and a Korean woman, and his son Shi Gang was born to one of his Jurchen wives. The surnames of his Jurchen wives were Mo-nien and Na-ho; the surname of his Korean wife was Li; and the surname of his Han Chinese wife was Shi. Shi Tianze defected to Mongol forces upon their invasion of the Jin dynasty. His son Shi Gang married a Kerait woman; the Kerait were Mongolified Turkic people and were considered part of the "Mongol nation". Shi Tianze (Shih T'ien-tse), Zhang Rou (Chang Jou, 張柔), and Yan Shi (Yen Shih, 嚴實) and other high ranking Chinese who served in the Jin dynasty and defected to the Mongols helped build the structure for the administration of the new state.

The first geological map of the U.S. was produced in 1809 by William Maclure. In 1807, Maclure commenced the self-imposed task of making a geological survey of the United States. Almost every state in the Union was traversed and mapped by him, the Allegheny Mountains being crossed and recrossed some 50 times. The results of his unaided labours were submitted to the American Philosophical Society in a memoir entitled Observations on the Geology of the United States explanatory of a Geological Map, and published in the Society's Transactions, together with the nation's first geological map. This antedates William Smith's geological map of England by six years, although it was constructed using a different classification of rocks.

How many years later was Maclure's memoir published after the map?


Orientalism, as theorized by Edward Said, refers to how the West developed an imaginative geography of the East. This imaginative geography relies on an essentializing discourse that represents neither the diversity nor the social reality of the East. Rather, by essentializing the East, this discourse uses the idea of place-based identities to create difference and distance between "we" the West and "them" the East, or "here" in the West and "there" in the East. This difference was particularly apparent in textual and visual works of early European studies of the Orient that positioned the East as irrational and backward in opposition to the rational and progressive West. Defining the East as a negative vision of itself, as its inferior, not only increased the West’s sense of self, but also was a way of ordering the East and making it known to the West so that it could be dominated and controlled. The discourse of Orientalism therefore served as an ideological justification of early Western imperialism, as it formed a body of knowledge and ideas that rationalized social, cultural, political, and economic control of other territories.

The pound-force has a metric counterpart, less commonly used than the newton: the kilogram-force (kgf) (sometimes kilopond), is the force exerted by standard gravity on one kilogram of mass. The kilogram-force leads to an alternate, but rarely used unit of mass: the metric slug (sometimes mug or hyl) is that mass that accelerates at 1 m·s−2 when subjected to a force of 1 kgf. The kilogram-force is not a part of the modern SI system, and is generally deprecated; however it still sees use for some purposes as expressing aircraft weight, jet thrust, bicycle spoke tension, torque wrench settings and engine output torque. Other arcane units of force include the sthène, which is equivalent to 1000 N, and the kip, which is equivalent to 1000 lbf.

What is the force exerted by standard gravity on one ton of mass?


Read this: A controversial aspect of imperialism is the defense and justification of empire-building based on seemingly rational grounds. J. A. Hobson identifies this justification on general grounds as: "It is desirable that the earth should be peopled, governed, and developed, as far as possible, by the races which can do this work best, i.e. by the races of highest 'social efficiency'". Many others argued that imperialism is justified for several different reasons. Friedrich Ratzel believed that in order for a state to survive, imperialism was needed. Halford Mackinder felt that Great Britain needed to be one of the greatest imperialists and therefore justified imperialism. The purportedly scientific nature of "Social Darwinism" and a theory of races formed a supposedly rational justification for imperialism. The rhetoric of colonizers being racially superior appears to have achieved its purpose, for example throughout Latin America "whiteness" is still prized today and various forms of blanqueamiento (whitening) are common.

 J. A. Hobson wanted which races to develop the world?

Read this: The main use for steam turbines is in electricity generation (in the 1990s about 90% of the world's electric production was by use of steam turbines) however the recent widespread application of large gas turbine units and typical combined cycle power plants has resulted in reduction of this percentage to the 80% regime for steam turbines. In electricity production, the high speed of turbine rotation matches well with the speed of modern electric generators, which are typically direct connected to their driving turbines. In marine service, (pioneered on the Turbinia), steam turbines with reduction gearing (although the Turbinia has direct turbines to propellers with no reduction gearbox) dominated large ship propulsion throughout the late 20th century, being more efficient (and requiring far less maintenance) than reciprocating steam engines. In recent decades, reciprocating Diesel engines, and gas turbines, have almost entirely supplanted steam propulsion for marine applications.

BSkyB's digital service was officially launched on 1 October 1998 under the name Sky Digital, although small-scale tests were carried out before then. At this time the use of the Sky Digital brand made an important distinction between the new service and Sky's analogue services. Key selling points were the improvement in picture and sound quality, increased number of channels and an interactive service branded Open.... now called Sky Active, BSkyB competed with the ONdigital (later ITV Digital) terrestrial offering and cable services. Within 30 days, over 100,000 digiboxes had been sold, which help bolstered BSkyB's decision to give away free digiboxes and minidishes from May 1999.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What did BSkyB name their interactive service?


The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) beginning in 1985 to promote advanced research and education networking in the United States. NSFNET was also the name given to several nationwide backbone networks operating at speeds of 56 kbit/s, 1.5 Mbit/s (T1), and 45 Mbit/s (T3) that were constructed to support NSF's networking initiatives from 1985-1995. Initially created to link researchers to the nation's NSF-funded supercomputing centers, through further public funding and private industry partnerships it developed into a major part of the Internet backbone.

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.

How did Celeron handle business on trip?

EU Competition law has its origins in the European Coal and Steel Community (ECSC) agreement between France, Italy, Belgium, the Netherlands, Luxembourg and Germany in 1951 following the second World War. The agreement aimed to prevent Germany from re-establishing dominance in the production of coal and steel as members felt that its dominance had contributed to the outbreak of the war. Article 65 of the agreement banned cartels and article 66 made provisions for concentrations, or mergers, and the abuse of a dominant position by companies. This was the first time that competition law principles were included in a plurilateral regional agreement and established the trans-European model of competition law. In 1957 competition rules were included in the Treaty of Rome, also known as the EC Treaty, which established the European Economic Community (EEC). The Treaty of Rome established the enactment of competition law as one of the main aims of the EEC through the "institution of a system ensuring that competition in the common market is not distorted". The two central provisions on EU competition law on companies were established in article 85, which prohibited anti-competitive agreements, subject to some exemptions, and article 86 prohibiting the abuse of dominant position. The treaty also established principles on competition law for member states, with article 90 covering public undertakings, and article 92 making provisions on state aid. Regulations on mergers were not included as member states could not establish consensus on the issue at the time.

When were competition rules included in the Treaty of Rome?

Every May since 1987, the University of Chicago has held the University of Chicago Scavenger Hunt, in which large teams of students compete to obtain notoriously esoteric items from a list. Since 1963, the Festival of the Arts (FOTA) takes over campus for 7–10 days of exhibitions and interactive artistic endeavors. Every January, the university holds a week-long winter festival, Kuviasungnerk/Kangeiko, which include early morning exercise routines and fitness workshops. The university also annually holds a summer carnival and concert called Summer Breeze that hosts outside musicians, and is home to Doc Films, a student film society founded in 1932 that screens films nightly at the university. Since 1946, the university has organized the Latke-Hamantash Debate, which involves humorous discussions about the relative merits and meanings of latkes and hamantashen.

Which debate has been organized by the U of C since 1987?


The first Huguenots to leave France sought freedom from persecution in Switzerland and the Netherlands.[citation needed] A group of Huguenots was part of the French colonisers who arrived in Brazil in 1555 to found France Antarctique. A couple of ships with around 500 people arrived at the Guanabara Bay, present-day Rio de Janeiro, and settled in a small island. A fort, named Fort Coligny, was built to protect them from attack from the Portuguese troops and Brazilian Native Americans. It was an attempt to establish a French colony in South America. The fort was destroyed in 1560 by the Portuguese, who captured part of the Huguenots. The Portuguese threatened the prisoners with death if they did not convert to Catholicism. The Huguenots of Guanabara, as they are now known, produced a declaration of faith to express their beliefs to the Portuguese. This was their death sentence. This document, the Guanabara Confession of Faith, became the first Protestant confession of faith in the whole of the Americas.[citation needed]

In 1271, Kublai Khan imposed the name Great Yuan (Chinese: 大元; pinyin: Dà Yuán; Wade–Giles: Ta-Yüan), establishing the Yuan dynasty. "Dà Yuán" (大元) is from the sentence "大哉乾元" (dà zai Qián Yuán / "Great is Qián, the Primal") in the Commentaries on the Classic of Changes (I Ching) section regarding Qián (乾). The counterpart in Mongolian language was Dai Ön Ulus, also rendered as Ikh Yuan Üls or Yekhe Yuan Ulus. In Mongolian, Dai Ön (Great Yuan) is often used in conjunction with the "Yeke Mongghul Ulus" (lit. "Great Mongol State"), resulting in Dai Ön Yeke Mongghul Ulus (Mongolian script: ), meaning "Great Yuan Great Mongol State". The Yuan dynasty is also known as the "Mongol dynasty" or "Mongol Dynasty of China", similar to the names "Manchu dynasty" or "Manchu Dynasty of China" for the Qing dynasty. Furthermore, the Yuan is sometimes known as the "Empire of the Great Khan" or "Khanate of the Great Khan", which particularly appeared on some Yuan maps, since Yuan emperors held the nominal title of Great Khan. Nevertheless, both terms can also refer to the khanate within the Mongol Empire directly ruled by Great Khans before the actual establishment of the Yuan dynasty by Kublai Khan in 1271.

When did Khan establish the Great Yuan?

Imperialism has played an important role in the histories of Japan, Korea, the Assyrian Empire, the Chinese Empire, the Roman Empire, Greece, the Byzantine Empire, the Persian Empire, the Ottoman Empire, Ancient Egypt, the British Empire, India, and many other empires. Imperialism was a basic component to the conquests of Genghis Khan during the Mongol Empire, and of other war-lords. Historically recognized Muslim empires number in the dozens. Sub-Saharan Africa has also featured dozens of empires that predate the European colonial era, for example the Ethiopian Empire, Oyo Empire, Asante Union, Luba Empire, Lunda Empire, and Mutapa Empire. The Americas during the pre-Columbian era also had large empires such as the Aztec Empire and the Incan Empire.

From Italy, the disease spread northwest across Europe, striking France, Spain, Portugal and England by June 1348, then turned and spread east through Germany and Scandinavia from 1348 to 1350. It was introduced in Norway in 1349 when a ship landed at Askøy, then spread to Bjørgvin (modern Bergen) and Iceland. Finally it spread to northwestern Russia in 1351. The plague was somewhat less common in parts of Europe that had smaller trade relations with their neighbours, including the Kingdom of Poland, the majority of the Basque Country, isolated parts of Belgium and the Netherlands, and isolated alpine villages throughout the continent.

What country's ship landed at Oskoy?


Oxygen:

People who climb mountains or fly in non-pressurized fixed-wing aircraft sometimes have supplemental O
2 supplies.[h] Passengers traveling in (pressurized) commercial airplanes have an emergency supply of O
2 automatically supplied to them in case of cabin depressurization. Sudden cabin pressure loss activates chemical oxygen generators above each seat, causing oxygen masks to drop. Pulling on the masks "to start the flow of oxygen" as cabin safety instructions dictate, forces iron filings into the sodium chlorate inside the canister. A steady stream of oxygen gas is then produced by the exothermic reaction.

Read this: Stadtholder William III of Orange, who later became King of England, emerged as the strongest opponent of king Louis XIV after the French attacked the Dutch Republic in 1672. William formed the League of Augsburg as a coalition to oppose Louis and the French state. Consequently, many Huguenots considered the wealthy and Calvinist Dutch Republic, which led the opposition to Louis XIV, as the most attractive country for exile after the revocation of the Edict of Nantes. They also found many French-speaking Calvinist churches there.

Closely related fields in theoretical computer science are analysis of algorithms and computability theory. A key distinction between analysis of algorithms and computational complexity theory is that the former is devoted to analyzing the amount of resources needed by a particular algorithm to solve a problem, whereas the latter asks a more general question about all possible algorithms that could be used to solve the same problem. More precisely, it tries to classify problems that can or cannot be solved with appropriately restricted resources. In turn, imposing restrictions on the available resources is what distinguishes computational complexity from computability theory: the latter theory asks what kind of problems can, in principle, be solved algorithmically.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What field of computer science analyzes all possible algorithms in aggregate to determine the resource requirements needed to solve to a given problem?

In addition to identifying rocks in the field, petrologists identify rock samples in the laboratory. Two of the primary methods for identifying rocks in the laboratory are through optical microscopy and by using an electron microprobe. In an optical mineralogy analysis, thin sections of rock samples are analyzed through a petrographic microscope, where the minerals can be identified through their different properties in plane-polarized and cross-polarized light, including their birefringence, pleochroism, twinning, and interference properties with a conoscopic lens. In the electron microprobe, individual locations are analyzed for their exact chemical compositions and variation in composition within individual crystals. Stable and radioactive isotope studies provide insight into the geochemical evolution of rock units.

What kind of rock samples are analyzed by an electron microprobe?


Read this: Socialists attribute the vast disparities in wealth to the private ownership of the means of production by a class of owners, creating a situation where a small portion of the population lives off unearned property income by virtue of ownership titles in capital equipment, financial assets and corporate stock. By contrast, the vast majority of the population is dependent on income in the form of a wage or salary. In order to rectify this situation, socialists argue that the means of production should be socially owned so that income differentials would be reflective of individual contributions to the social product.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What doesn't private ownership create a situation of?


Read this: Economist Joseph Stiglitz argues that rather than explaining concentrations of wealth and income, market forces should serve as a brake on such concentration, which may better be explained by the non-market force known as "rent-seeking". While the market will bid up compensation for rare and desired skills to reward wealth creation, greater productivity, etc., it will also prevent successful entrepreneurs from earning excess profits by fostering competition to cut prices, profits and large compensation. A better explainer of growing inequality, according to Stiglitz, is the use of political power generated by wealth by certain groups to shape government policies financially beneficial to them. This process, known to economists as rent-seeking, brings income not from creation of wealth but from "grabbing a larger share of the wealth that would otherwise have been produced without their effort"

Income not from the creation of wealth but by grabbing a larger share of it is know to economists by what term?

After the Greeks, little happened with the study of prime numbers until the 17th century. In 1640 Pierre de Fermat stated (without proof) Fermat's little theorem (later proved by Leibniz and Euler). Fermat also conjectured that all numbers of the form 22n + 1 are prime (they are called Fermat numbers) and he verified this up to n = 4 (or 216 + 1). However, the very next Fermat number 232 + 1 is composite (one of its prime factors is 641), as Euler discovered later, and in fact no further Fermat numbers are known to be prime. The French monk Marin Mersenne looked at primes of the form 2p − 1, with p a prime. They are called Mersenne primes in his honor.

In what year did Pierre de Fermat declare Fermat's little theorem?
