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

Some elements of the Brotherhood, though perhaps against orders, did engage in violence against the government, and its founder Al-Banna was assassinated in 1949 in retaliation for the assassination of Egypt's premier Mahmud Fami Naqrashi three months earlier. The Brotherhood has suffered periodic repression in Egypt and has been banned several times, in 1948 and several years later following confrontations with Egyptian president Gamal Abdul Nasser, who jailed thousands of members for several years.

Immunology is strongly experimental in everyday practice but is also characterized by an ongoing theoretical attitude. Many theories have been suggested in immunology from the end of the nineteenth century up to the present time. The end of the 19th century and the beginning of the 20th century saw a battle between "cellular" and "humoral" theories of immunity. According to the cellular theory of immunity, represented in particular by Elie Metchnikoff, it was cells – more precisely, phagocytes – that were responsible for immune responses. In contrast, the humoral theory of immunity, held, among others, by Robert Koch and Emil von Behring, stated that the active immune agents were soluble components (molecules) found in the organism’s “humors” rather than its cells.

Who were the main detractors of the humoral theory of immunity?

It was in this place in Tours that the prétendus réformés ("these supposedly 'reformed'") habitually gathered at night, both for political purposes, and for prayer and singing psalms. Such explanations have been traced to the contemporary, Reguier de la Plancha (d. 1560), who in De l'Estat de France offered the following account as to the origin of the name, as cited by The Cape Monthly:

James Bryant Conant (president, 1933–1953) reinvigorated creative scholarship to guarantee its preeminence among research institutions. He saw higher education as a vehicle of opportunity for the talented rather than an entitlement for the wealthy, so Conant devised programs to identify, recruit, and support talented youth. In 1943, he asked the faculty make a definitive statement about what general education ought to be, at the secondary as well as the college level. The resulting Report, published in 1945, was one of the most influential manifestos in the history of American education in the 20th century.

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

When did BSkyB announce it's intention to replace it's free-to-air digital channels?


In regard to companies, the Court of Justice held in R (Daily Mail and General Trust plc) v HM Treasury that member states could restrict a company moving its seat of business, without infringing TFEU article 49. This meant the Daily Mail newspaper's parent company could not evade tax by shifting its residence to the Netherlands without first settling its tax bills in the UK. The UK did not need to justify its action, as rules on company seats were not yet harmonised. By contrast, in Centros Ltd v Erhversus-og Selkabssyrelsen the Court of Justice found that a UK limited company operating in Denmark could not be required to comply with Denmark's minimum share capital rules. UK law only required £1 of capital to start a company, while Denmark's legislature took the view companies should only be started up if they had 200,000 Danish krone (around €27,000) to protect creditors if the company failed and went insolvent. The Court of Justice held that Denmark's minimum capital law infringed Centros Ltd's freedom of establishment and could not be justified, because a company in the UK could admittedly provide services in Denmark without being established there, and there were less restrictive means of achieving the aim of creditor protection. This approach was criticised as potentially opening the EU to unjustified regulatory competition, and a race to the bottom in standards, like in the US where the state Delaware attracts most companies and is often argued to have the worst standards of accountability of boards, and low corporate taxes as a result. Similarly in Überseering BV v Nordic Construction GmbH the Court of Justice held that a German court could not deny a Dutch building company the right to enforce a contract in Germany on the basis that it was not validly incorporated in Germany. Although restrictions on freedom of establishment could be justified by creditor protection, labour rights to participate in work, or the public interest in collecting taxes, denial of capacity went too far: it was an "outright negation" of the right of establishment. However, in Cartesio Oktató és Szolgáltató bt the Court of Justice affirmed again that because corporations are created by law, they are in principle subject to any rules for formation that a state of incorporation wishes to impose. This meant that the Hungarian authorities could prevent a company from shifting its central administration to Italy while it still operated and was incorporated in Hungary. Thus, the court draws a distinction between the right of establishment for foreign companies (where restrictions must be justified), and the right of the state to determine conditions for companies incorporated in its territory, although it is not entirely clear why.

John Schmitt and Ben Zipperer (2006) of the CEPR point to economic liberalism and the reduction of business regulation along with the decline of union membership as one of the causes of economic inequality. In an analysis of the effects of intensive Anglo-American liberal policies in comparison to continental European liberalism, where unions have remained strong, they concluded "The U.S. economic and social model is associated with substantial levels of social exclusion, including high levels of income inequality, high relative and absolute poverty rates, poor and unequal educational outcomes, poor health outcomes, and high rates of crime and incarceration. At the same time, the available evidence provides little support for the view that U.S.-style labor-market flexibility dramatically improves labor-market outcomes. Despite popular prejudices to the contrary, the U.S. economy consistently affords a lower level of economic mobility than all the continental European countries for which data is available."

Read this: 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.

Pattern recognition receptors are proteins used by nearly all organisms to identify molecules associated with pathogens. Antimicrobial peptides called defensins are an evolutionarily conserved component of the innate immune response found in all animals and plants, and represent the main form of invertebrate systemic immunity. The complement system and phagocytic cells are also used by most forms of invertebrate life. Ribonucleases and the RNA interference pathway are conserved across all eukaryotes, and are thought to play a role in the immune response to viruses.

Read this: 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.

The plague theory was first significantly challenged by the work of British bacteriologist J. F. D. Shrewsbury in 1970, who noted that the reported rates of mortality in rural areas during the 14th-century pandemic were inconsistent with the modern bubonic plague, leading him to conclude that contemporary accounts were exaggerations. In 1984 zoologist Graham Twigg produced the first major work to challenge the bubonic plague theory directly, and his doubts about the identity of the Black Death have been taken up by a number of authors, including Samuel K. Cohn, Jr. (2002), David Herlihy (1997), and Susan Scott and Christopher Duncan (2001).

During this time, the discovery of oil in the North Sea and the following "It's Scotland's oil" campaign of the Scottish National Party (SNP) resulted in rising support for Scottish independence, as well as the SNP. The party argued that the revenues from the oil were not benefitting Scotland as much as they should. The combined effect of these events led to Prime Minister Wilson committing his government to some form of devolved legislature in 1974. However, it was not until 1978 that final legislative proposals for a Scottish Assembly were passed by the United Kingdom Parliament.

Oxygen:

Paleoclimatologists measure the ratio of oxygen-18 and oxygen-16 in the shells and skeletons of marine organisms to determine what the climate was like millions of years ago (see oxygen isotope ratio cycle). Seawater molecules that contain the lighter isotope, oxygen-16, evaporate at a slightly faster rate than water molecules containing the 12% heavier oxygen-18; this disparity increases at lower temperatures. During periods of lower global temperatures, snow and rain from that evaporated water tends to be higher in oxygen-16, and the seawater left behind tends to be higher in oxygen-18. Marine organisms then incorporate more oxygen-18 into their skeletons and shells than they would in a warmer climate. Paleoclimatologists also directly measure this ratio in the water molecules of ice core samples that are up to several hundreds of thousands of years old.

Construction:

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

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

This contributed to the "Oil Shock". After 1971, OPEC was slow to readjust prices to reflect this depreciation. From 1947 to 1967, the dollar price of oil had risen by less than two percent per year. Until the oil shock, the price had also remained fairly stable versus other currencies and commodities. OPEC ministers had not developed institutional mechanisms to update prices in sync with changing market conditions, so their real incomes lagged. The substantial price increases of 1973–1974 largely returned their prices and corresponding incomes to Bretton Woods levels in terms of commodities such as gold.

From 1947 to 1967, how much did the price of oil increase?


Islamism, also known as Political Islam (Arabic: إسلام سياسي islām siyāsī), is an Islamic revival movement often characterized by moral conservatism, literalism, and the attempt "to implement Islamic values in all spheres of life." Islamism favors the reordering of government and society in accordance with the Shari'a. The different Islamist movements have been described as "oscillating between two poles": at one end is a strategy of Islamization of society through state power seized by revolution or invasion; at the other "reformist" pole Islamists work to Islamize society gradually "from the bottom up". The movements have "arguably altered the Middle East more than any trend since the modern states gained independence", redefining "politics and even borders" according to one journalist (Robin Wright).

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.

Why should someone not commit a crime when they are protesting?


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

According to Sheldon Ungar's comparison with global warming, the actors in the ozone depletion case had a better understanding of scientific ignorance and uncertainties. The ozone case communicated to lay persons "with easy-to-understand bridging metaphors derived from the popular culture" and related to "immediate risks with everyday relevance", while the public opinion on climate change sees no imminent danger. The stepwise mitigation of the ozone layer challenge was based as well on successfully reducing regional burden sharing conflicts. In case of the IPCC conclusions and the failure of the Kyoto Protocol, varying regional cost-benefit analysis and burden-sharing conflicts with regard to the distribution of emission reductions remain an unsolved problem. In the UK, a report for a House of Lords committee asked to urge the IPCC to involve better assessments of costs and benefits of climate change but the Stern Review ordered by the UK government made a stronger argument in favor to combat human-made climate change.

Ctenophores may be abundant during the summer months in some coastal locations, but in other places they are uncommon and difficult to find. In bays where they occur in very high numbers, predation by ctenophores may control the populations of small zooplanktonic organisms such as copepods, which might otherwise wipe out the phytoplankton (planktonic plants), which are a vital part of marine food chains. One ctenophore, Mnemiopsis, has accidentally been introduced into the Black Sea, where it is blamed for causing fish stocks to collapse by eating both fish larvae and organisms that would otherwise have fed the fish. The situation was aggravated by other factors, such as over-fishing and long-term environmental changes that promoted the growth of the Mnemiopsis population. The later accidental introduction of Beroe helped to mitigate the problem, as Beroe preys on other ctenophores.

Using boiling water to produce mechanical motion goes back over 2000 years, but early devices were not practical. The Spanish inventor Jerónimo de Ayanz y Beaumont obtained the first patent for a steam engine in 1606. In 1698 Thomas Savery patented a steam pump that used steam in direct contact with the water being pumped. Savery's steam pump used condensing steam to create a vacuum and draw water into a chamber, and then applied pressurized steam to further pump the water. Thomas Newcomen's atmospheric engine was the first commercial true steam engine using a piston, and was used in 1712 for pumping in a mine.

In what year did Savery patent his steam pump?


Some disagree with such double or triple non-French linguistic origins, arguing that for the word to have spread into common use in France, it must have originated in the French language. The "Hugues hypothesis" argues that the name was derived by association with Hugues Capet, king of France, who reigned long before the Reformation. He was regarded by the Gallicans and Protestants as a noble man who respected people's dignity and lives. Janet Gray and other supporters of the hypothesis suggest that the name huguenote would be roughly equivalent to little Hugos, or those who want Hugo.

Reactive oxygen species, such as superoxide ion (O−
2) and hydrogen peroxide (H
2O
2), are dangerous by-products of oxygen use in organisms. Parts of the immune system of higher organisms create peroxide, superoxide, and singlet oxygen to destroy invading microbes. Reactive oxygen species also play an important role in the hypersensitive response of plants against pathogen attack. Oxygen is toxic to obligately anaerobic organisms, which were the dominant form of early life on Earth until O
2 began to accumulate in the atmosphere about 2.5 billion years ago during the Great Oxygenation Event, about a billion years after the first appearance of these organisms.

BSkyB initially charged additional subscription fees for using a Sky+ PVR with their service; waiving the charge for subscribers whose package included two or more premium channels. This changed as from 1 July 2007, and now customers that have Sky+ and subscribe to any BSkyB subscription package get Sky+ included at no extra charge. Customers that do not subscribe to BSkyB's channels can still pay a monthly fee to enable Sky+ functions. In January 2010 BSkyB discontinued the Sky+ Box, limited the standard Sky Box to Multiroom upgrade only and started to issue the Sky+HD Box as standard, thus giving all new subscribers the functions of Sky+. In February 2011 BSkyB discontinued the non-HD variant of its Multiroom box, offering a smaller version of the SkyHD box without Sky+ functionality. In September 2007, Sky launched a new TV advertising campaign targeting Sky+ at women. As of 31 March 2008, Sky had 3,393,000 Sky+ users.

Read this: In the modern industrialized world, construction usually involves the translation of designs into reality. A formal design team may be assembled to plan the physical proceedings, and to integrate those proceedings with the other parts. The design usually consists of drawings and specifications, usually prepared by a design team including Architect, civil engineers, mechanical engineers, electrical engineers, structural engineers, fire protection engineers, planning consultants, architectural consultants, and archaeological consultants. The design team is most commonly employed by (i.e. in contract with) the property owner. Under this system, once the design is completed by the design team, a number of construction companies or construction management companies may then be asked to make a bid for the work, either based directly on the design, or on the basis of drawings and a bill of quantities provided by a quantity surveyor. Following evaluation of bids, the owner typically awards a contract to the most cost efficient bidder.

Read this: In Marxian analysis, capitalist firms increasingly substitute capital equipment for labor inputs (workers) under competitive pressure to reduce costs and maximize profits. Over the long-term, this trend increases the organic composition of capital, meaning that less workers are required in proportion to capital inputs, increasing unemployment (the "reserve army of labour"). This process exerts a downward pressure on wages. The substitution of capital equipment for labor (mechanization and automation) raises the productivity of each worker, resulting in a situation of relatively stagnant wages for the working class amidst rising levels of property income for the capitalist class.

By autumn 1347, the plague reached Alexandria in Egypt, probably through the port's trade with Constantinople, and ports on the Black Sea. During 1347, the disease travelled eastward to Gaza, and north along the eastern coast to cities in Lebanon, Syria and Palestine, including Ashkelon, Acre, Jerusalem, Sidon, Damascus, Homs, and Aleppo. In 1348–49, the disease reached Antioch. The city's residents fled to the north, most of them dying during the journey, but the infection had been spread to the people of Asia Minor.[citation needed]

The other category of schools are those run and partly or fully funded by private individuals, private organizations and religious groups. The ones that accept government funds are called 'aided' schools. The private 'un-aided' schools are fully funded by private parties. The standard and the quality of education is quite high. Technically, these would be categorized as private schools, but many of them have the name "Public School" appended to them, e.g., the Galaxy Public School in Kathmandu. Most of the middle-class families send their children to such schools, which might be in their own city or far off, like boarding schools. The medium of education is English, but as a compulsory subject, Nepali and/or the state's official language is also taught. Preschool education is mostly limited to organized neighbourhood nursery schools.

Computational complexity theory is a branch of the theory of computation in theoretical computer science that focuses on classifying computational problems according to their inherent difficulty, and relating those classes to each other. A computational problem is understood to be a task that is in principle amenable to being solved by a computer, which is equivalent to stating that the problem may be solved by mechanical application of mathematical steps, such as an algorithm.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What is understood to be a task that is in principle not amendable to being solved by a computer?


Read this: 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.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): When were these settlers naturalized as English colonists?


One of the more notable applications of printing technology was the chao, the paper money of the Yuan. Chao were made from the bark of mulberry trees. The Yuan government used woodblocks to print paper money, but switched to bronze plates in 1275. The Mongols experimented with establishing the Chinese-style paper monetary system in Mongol-controlled territories outside of China. The Yuan minister Bolad was sent to Iran, where he explained Yuan paper money to the Il-khanate court of Gaykhatu. The Il-khanate government issued paper money in 1294, but public distrust of the exotic new currency doomed the experiment.

Louis XIV gained the throne in 1643 and acted increasingly aggressively to force the Huguenots to convert. At first he sent missionaries, backed by a fund to financially reward converts to Catholicism. Then he imposed penalties, closed Huguenot schools and excluded them from favored professions. Escalating, he instituted dragonnades, which included the occupation and looting of Huguenot homes by military troops, in an effort to forcibly convert them. In 1685, he issued the Edict of Fontainebleau, revoking the Edict of Nantes and declaring Protestantism illegal.[citation needed]

Prime ideals are the points of algebro-geometric objects, via the notion of the spectrum of a ring. Arithmetic geometry also benefits from this notion, and many concepts exist in both geometry and number theory. For example, factorization or ramification of prime ideals when lifted to an extension field, a basic problem of algebraic number theory, bears some resemblance with ramification in geometry. Such ramification questions occur even in number-theoretic questions solely concerned with integers. For example, prime ideals in the ring of integers of quadratic number fields can be used in proving quadratic reciprocity, a statement that concerns the solvability of quadratic equations

Read this: The heat required for boiling the water and supplying the steam can be derived from various sources, most commonly from burning combustible materials with an appropriate supply of air in a closed space (called variously combustion chamber, firebox). In some cases the heat source is a nuclear reactor, geothermal energy, solar energy or waste heat from an internal combustion engine or industrial process. In the case of model or toy steam engines, the heat source can be an electric heating element.

Aside from firebox, what is another name for the space in which combustible material is burned in the engine?

Modern primality tests for general numbers n can be divided into two main classes, probabilistic (or "Monte Carlo") and deterministic algorithms. Deterministic algorithms provide a way to tell for sure whether a given number is prime or not. For example, trial division is a deterministic algorithm because, if performed correctly, it will always identify a prime number as prime and a composite number as composite. Probabilistic algorithms are normally faster, but do not completely prove that a number is prime. These tests rely on testing a given number in a partly random way. For example, a given test might pass all the time if applied to a prime number, but pass only with probability p if applied to a composite number. If we repeat the test n times and pass every time, then the probability that our number is composite is 1/(1-p)n, which decreases exponentially with the number of tests, so we can be as sure as we like (though never perfectly sure) that the number is prime. On the other hand, if the test ever fails, then we know that the number is composite.
Try to answer this question if possible (otherwise reply "unanswerable"): How many modern types of algorithm tests for general numbers n are there?


The fundamental theorem of arithmetic continues to hold in unique factorization domains. An example of such a domain is the Gaussian integers Z[i], that is, the set of complex numbers of the form a + bi where i denotes the imaginary unit and a and b are arbitrary integers. Its prime elements are known as Gaussian primes. Not every prime (in Z) is a Gaussian prime: in the bigger ring Z[i], 2 factors into the product of the two Gaussian primes (1 + i) and (1 − i). Rational primes (i.e. prime elements in Z) of the form 4k + 3 are Gaussian primes, whereas rational primes of the form 4k + 1 are not.

Exceptional examples of the bourgeois architecture of the later periods were not restored by the communist authorities after the war (like mentioned Kronenberg Palace and Insurance Company Rosja building) or they were rebuilt in socialist realism style (like Warsaw Philharmony edifice originally inspired by Palais Garnier in Paris). Despite that the Warsaw University of Technology building (1899–1902) is the most interesting of the late 19th-century architecture. Some 19th-century buildings in the Praga district (the Vistula’s right bank) have been restored although many have been poorly maintained. Warsaw’s municipal government authorities have decided to rebuild the Saxon Palace and the Brühl Palace, the most distinctive buildings in prewar Warsaw.

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.

In what year did the Black Death spread into Iceland?


The embargo was not uniform across Europe. Of the nine members of the European Economic Community (EEC), the Netherlands faced a complete embargo, the UK and France received almost uninterrupted supplies (having refused to allow America to use their airfields and embargoed arms and supplies to both the Arabs and the Israelis), while the other six faced partial cutbacks. The UK had traditionally been an ally of Israel, and Harold Wilson's government supported the Israelis during the Six-Day War. His successor, Ted Heath, reversed this policy in 1970, calling for Israel to withdraw to its pre-1967 borders.

Read this: Mortgage bankers, accountants, and cost engineers are likely participants in creating an overall plan for the financial management of the building construction project. The presence of the mortgage banker is highly likely, even in relatively small projects since the owner's equity in the property is the most obvious source of funding for a building project. Accountants act to study the expected monetary flow over the life of the project and to monitor the payouts throughout the process. Cost engineers and estimators apply expertise to relate the work and materials involved to a proper valuation. Cost overruns with government projects have occurred when the contractor identified change orders or project changes that increased costs, which are not subject to competition from other firms as they have already been eliminated from consideration after the initial bid.

Southern California contains a Mediterranean climate, with infrequent rain and many sunny days. Summers are hot and dry, while winters are a bit warm or mild and wet. Serious rain can occur unusually. In the summers, temperature ranges are 90-60's while as winters are 70-50's, usually all of Southern California have Mediterranean climate. But snow is very rare in the Southwest of the state, it occurs on the Southeast of the state.

In 1781 James Watt patented a steam engine that produced continuous rotary motion. Watt's ten-horsepower engines enabled a wide range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained. By 1883, engines that could provide 10,000 hp had become feasible. The stationary steam engine was a key component of the Industrial Revolution, allowing factories to locate where water power was unavailable. The atmospheric engines of Newcomen and Watt were large compared to the amount of power they produced, but high pressure steam engines were light enough to be applied to vehicles such as traction engines and the railway locomotives.

Paul Revere was descended from Huguenot refugees, as was Henry Laurens, who signed the Articles of Confederation for South Carolina; Jack Jouett, who made the ride from Cuckoo Tavern to warn Thomas Jefferson and others that Tarleton and his men were on their way to arrest him for crimes against the king; Francis Marion, and a number of other leaders of the American Revolution and later statesmen. The last active Huguenot congregation in North America worships in Charleston, South Carolina, at a church that dates to 1844. The Huguenot Society of America maintains Manakin Episcopal Church in Virginia as an historic shrine with occasional services. The Society has chapters in numerous states, with the one in Texas being the largest.

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

Petrologists can also use fluid inclusion data and perform high temperature and pressure physical experiments to understand the temperatures and pressures at which different mineral phases appear, and how they change through igneous and metamorphic processes. This research can be extrapolated to the field to understand metamorphic processes and the conditions of crystallization of igneous rocks. This work can also help to explain processes that occur within the Earth, such as subduction and magma chamber evolution.

The development of plate tectonics provided a physical basis for many observations of the solid Earth. Long linear regions of geologic features could be explained as plate boundaries. Mid-ocean ridges, high regions on the seafloor where hydrothermal vents and volcanoes exist, were explained as divergent boundaries, where two plates move apart. Arcs of volcanoes and earthquakes were explained as convergent boundaries, where one plate subducts under another. Transform boundaries, such as the San Andreas fault system, resulted in widespread powerful earthquakes. Plate tectonics also provided a mechanism for Alfred Wegener's theory of continental drift, in which the continents move across the surface of the Earth over geologic time. They also provided a driving force for crustal deformation, and a new setting for the observations of structural geology. The power of the theory of plate tectonics lies in its ability to combine all of these observations into a single theory of how the lithosphere moves over the convecting mantle.

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

Oxygen:

The other major method of producing O
2 gas involves passing a stream of clean, dry air through one bed of a pair of identical zeolite molecular sieves, which absorbs the nitrogen and delivers a gas stream that is 90% to 93% O
2. Simultaneously, nitrogen gas is released from the other nitrogen-saturated zeolite bed, by reducing the chamber operating pressure and diverting part of the oxygen gas from the producer bed through it, in the reverse direction of flow. After a set cycle time the operation of the two beds is interchanged, thereby allowing for a continuous supply of gaseous oxygen to be pumped through a pipeline. This is known as pressure swing adsorption. Oxygen gas is increasingly obtained by these non-cryogenic technologies (see also the related vacuum swing adsorption).

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

Killer T cells are a sub-group of T cells that kill cells that are infected with viruses (and other pathogens), or are otherwise damaged or dysfunctional. As with B cells, each type of T cell recognizes a different antigen. Killer T cells are activated when their T cell receptor (TCR) binds to this specific antigen in a complex with the MHC Class I receptor of another cell. Recognition of this MHC:antigen complex is aided by a co-receptor on the T cell, called CD8. The T cell then travels throughout the body in search of cells where the MHC I receptors bear this antigen. When an activated T cell contacts such cells, it releases cytotoxins, such as perforin, which form pores in the target cell's plasma membrane, allowing ions, water and toxins to enter. The entry of another toxin called granulysin (a protease) induces the target cell to undergo apoptosis. T cell killing of host cells is particularly important in preventing the replication of viruses. T cell activation is tightly controlled and generally requires a very strong MHC/antigen activation signal, or additional activation signals provided by "helper" T cells (see below).

The University of Chicago has been the site of some important experiments and academic movements. In economics, the university has played an important role in shaping ideas about the free market and is the namesake of the Chicago school of economics, the school of economic thought supported by Milton Friedman and other economists. The university's sociology department was the first independent sociology department in the United States and gave birth to the Chicago school of sociology. In physics, the university was the site of the Chicago Pile-1 (the first self-sustained man-made nuclear reaction, part of the Manhattan Project), of Robert Millikan's oil-drop experiment that calculated the charge of the electron, and of the development of radiocarbon dating by Willard F. Libby in 1947. The chemical experiment that tested how life originated on early Earth, the Miller–Urey experiment, was conducted at the university. REM sleep was discovered at the university in 1953 by Nathaniel Kleitman and Eugene Aserinsky.

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


Because of their soft, gelatinous bodies, ctenophores are extremely rare as fossils, and fossils that have been interpreted as ctenophores have been found only in lagerstätten, places where the environment was exceptionally suited to preservation of soft tissue. Until the mid-1990s only two specimens good enough for analysis were known, both members of the crown group, from the early Devonian (Emsian) period. Three additional putative species were then found in the Burgess Shale and other Canadian rocks of similar age, about 505 million years ago in the mid-Cambrian period. All three apparently lacked tentacles but had between 24 and 80 comb rows, far more than the 8 typical of living species. They also appear to have had internal organ-like structures unlike anything found in living ctenophores. One of the fossil species first reported in 1996 had a large mouth, apparently surrounded by a folded edge that may have been muscular. Evidence from China a year later suggests that such ctenophores were widespread in the Cambrian, but perhaps very different from modern species – for example one fossil's comb-rows were mounted on prominent vanes. The Ediacaran Eoandromeda could putatively represent a comb jelly.

Huguenot:

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 his extensively detailed report, Céloron wrote, "All I can say is that the Natives of these localities are very badly disposed towards the French, and are entirely devoted to the English. I don't know in what way they could be brought back." Even before his return to Montreal, reports on the situation in the Ohio Country were making their way to London and Paris, each side proposing that action be taken. William Shirley, the expansionist governor of the Province of Massachusetts Bay, was particularly forceful, stating that British colonists would not be safe as long as the French were present. Conflicts between the colonies, accomplished through raiding parties that included Indian allies, had taken place for decades, leading to a brisk trade in European colonial captives from either side.

For the complexity classes defined in this way, it is desirable to prove that relaxing the requirements on (say) computation time indeed defines a bigger set of problems. In particular, although DTIME(n) is contained in DTIME(n2), it would be interesting to know if the inclusion is strict. For time and space requirements, the answer to such questions is given by the time and space hierarchy theorems respectively. They are called hierarchy theorems because they induce a proper hierarchy on the classes defined by constraining the respective resources. Thus there are pairs of complexity classes such that one is properly included in the other. Having deduced such proper set inclusions, we can proceed to make quantitative statements about how much more additional time or space is needed in order to increase the number of problems that can be solved.

What kind of statement is made in the effort of establishing the time and space requirements needed to enhance the ultimate number of problems solved?

Yuan dynasty:

The reason for the order of the classes and the reason why people were placed in a certain class was the date they surrendered to the Mongols, and had nothing to do with their ethnicity. The earlier they surrendered to the Mongols, the higher they were placed, the more the held out, the lower they were ranked. The Northern Chinese were ranked higher and Southern Chinese were ranked lower because southern China withstood and fought to the last before caving in.

From the mid-2000s, the university began a number of multimillion-dollar expansion projects. In 2008, the University of Chicago announced plans to establish the Milton Friedman Institute which attracted both support and controversy from faculty members and students. The institute will cost around $200 million and occupy the buildings of the Chicago Theological Seminary. During the same year, investor David G. Booth donated $300 million to the university's Booth School of Business, which is the largest gift in the university's history and the largest gift ever to any business school. In 2009, planning or construction on several new buildings, half of which cost $100 million or more, was underway. Since 2011, major construction projects have included the Jules and Gwen Knapp Center for Biomedical Discovery, a ten-story medical research center, and further additions to the medical campus of the University of Chicago Medical Center. In 2014 the University launched the public phase of a $4.5 billion fundraising campaign. In September 2015, the University received $100 million from The Pearson Family Foundation to establish The Pearson Institute for the Study and Resolution of Global Conflicts and The Pearson Global Forum at the Harris School of Public Policy Studies.

What intractability means in practice is open to debate. Saying that a problem is not in P does not imply that all large cases of the problem are hard or even that most of them are. For example, the decision problem in Presburger arithmetic has been shown not to be in P, yet algorithms have been written that solve the problem in reasonable times in most cases. Similarly, algorithms can solve the NP-complete knapsack problem over a wide range of sizes in less than quadratic time and SAT solvers routinely handle large instances of the NP-complete Boolean satisfiability problem.

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.

Read this: Construction is the process of constructing a building or infrastructure. Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client. Construction as an industry comprises six to nine percent of the gross domestic product of developed countries. Construction starts with planning,[citation needed] design, and financing and continues until the project is built and ready for use.

Read this: Islamism, also known as Political Islam (Arabic: إسلام سياسي islām siyāsī), is an Islamic revival movement often characterized by moral conservatism, literalism, and the attempt "to implement Islamic values in all spheres of life." Islamism favors the reordering of government and society in accordance with the Shari'a. The different Islamist movements have been described as "oscillating between two poles": at one end is a strategy of Islamization of society through state power seized by revolution or invasion; at the other "reformist" pole Islamists work to Islamize society gradually "from the bottom up". The movements have "arguably altered the Middle East more than any trend since the modern states gained independence", redefining "politics and even borders" according to one journalist (Robin Wright).

 One strategy of Islamization is to not seize power by what methods?

Read this: The advances made in the Middle East in botany and chemistry led medicine in medieval Islam substantially to develop pharmacology. Muhammad ibn Zakarīya Rāzi (Rhazes) (865–915), for instance, acted to promote the medical uses of chemical compounds. Abu al-Qasim al-Zahrawi (Abulcasis) (936–1013) pioneered the preparation of medicines by sublimation and distillation. His Liber servitoris is of particular interest, as it provides the reader with recipes and explains how to prepare the `simples’ from which were compounded the complex drugs then generally used. Sabur Ibn Sahl (d 869), was, however, the first physician to initiate pharmacopoedia, describing a large variety of drugs and remedies for ailments. Al-Biruni (973–1050) wrote one of the most valuable Islamic works on pharmacology, entitled Kitab al-Saydalah (The Book of Drugs), in which he detailed the properties of drugs and outlined the role of pharmacy and the functions and duties of the pharmacist. Avicenna, too, described no less than 700 preparations, their properties, modes of action, and their indications. He devoted in fact a whole volume to simple drugs in The Canon of Medicine. Of great impact were also the works by al-Maridini of Baghdad and Cairo, and Ibn al-Wafid (1008–1074), both of which were printed in Latin more than fifty times, appearing as De Medicinis universalibus et particularibus by 'Mesue' the younger, and the Medicamentis simplicibus by 'Abenguefit'. Peter of Abano (1250–1316) translated and added a supplement to the work of al-Maridini under the title De Veneris. Al-Muwaffaq’s contributions in the field are also pioneering. Living in the 10th century, he wrote The foundations of the true properties of Remedies, amongst others describing arsenious oxide, and being acquainted with silicic acid. He made clear distinction between sodium carbonate and potassium carbonate, and drew attention to the poisonous nature of copper compounds, especially copper vitriol, and also lead compounds. He also describes the distillation of sea-water for drinking.[verification needed]
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Which two compounds did Al-Muwaffaq combine?


On May 3, 1901, downtown Jacksonville was ravaged by a fire that started as a kitchen fire. Spanish moss at a nearby mattress factory was quickly engulfed in flames and enabling the fire to spread rapidly. In just eight hours, it swept through 146 city blocks, destroyed over 2,000 buildings, left about 10,000 homeless and killed 7 residents. The Confederate Monument in Hemming Park was one of the only landmarks to survive the fire. Governor Jennings declare martial law and sent the state militia to maintain order. On May 17 municipal authority resumed in Jacksonville. It is said the glow from the flames could be seen in Savannah, Georgia, and the smoke plumes seen in Raleigh, North Carolina. Known as the "Great Fire of 1901", it was one of the worst disasters in Florida history and the largest urban fire in the southeastern United States. Architect Henry John Klutho was a primary figure in the reconstruction of the city. The first multi-story structure built by Klutho was the Dyal-Upchurch Building in 1902. The St. James Building, built on the previous site of the St. James Hotel that burned down, was built in 1912 as Klutho's crowning achievement.

On the other hand, higher economic inequality tends to increase entrepreneurship rates at the individual level (self-employment). However, most of it is often based on necessity rather than opportunity. Necessity-based entrepreneurship is motivated by survival needs such as income for food and shelter ("push" motivations), whereas opportunity-based entrepreneurship is driven by achievement-oriented motivations ("pull") such as vocation and more likely to involve the pursue of new products, services, or underserved market needs. The economic impact of the former type of entrepreneurialism tends to be redistributive while the latter is expected to foster technological progress and thus have a more positive impact on economic growth.

For instance, while traveling in a moving vehicle at a constant velocity, the laws of physics do not change from being at rest. A person can throw a ball straight up in the air and catch it as it falls down without worrying about applying a force in the direction the vehicle is moving. This is true even though another person who is observing the moving vehicle pass by also observes the ball follow a curving parabolic path in the same direction as the motion of the vehicle. It is the inertia of the ball associated with its constant velocity in the direction of the vehicle's motion that ensures the ball continues to move forward even as it is thrown up and falls back down. From the perspective of the person in the car, the vehicle and everything inside of it is at rest: It is the outside world that is moving with a constant speed in the opposite direction. Since there is no experiment that can distinguish whether it is the vehicle that is at rest or the outside world that is at rest, the two situations are considered to be physically indistinguishable. Inertia therefore applies equally well to constant velocity motion as it does to rest.

The two what are considered to be physically distinguishable?


The needs of soy farmers have been used to justify many of the controversial transportation projects that are currently developing in the Amazon. The first two highways successfully opened up the rainforest and led to increased settlement and deforestation. The mean annual deforestation rate from 2000 to 2005 (22,392 km2 or 8,646 sq mi per year) was 18% higher than in the previous five years (19,018 km2 or 7,343 sq mi per year). Although deforestation has declined significantly in the Brazilian Amazon between 2004 and 2014, there has been an increase to the present day.

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

Answer this question, if possible (if impossible, reply "unanswerable"): What did industry do to the Rhine until the 1980s?


At Saint Evroul, a tradition of singing had developed and the choir achieved fame in Normandy. Under the Norman abbot Robert de Grantmesnil, several monks of Saint-Evroul fled to southern Italy, where they were patronised by Robert Guiscard and established a Latin monastery at Sant'Eufemia. There they continued the tradition of singing.

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.

Islamism:

For many years, Sudan had an Islamist regime under the leadership of Hassan al-Turabi. His National Islamic Front first gained influence when strongman General Gaafar al-Nimeiry invited members to serve in his government in 1979. Turabi built a powerful economic base with money from foreign Islamist banking systems, especially those linked with Saudi Arabia. He also recruited and built a cadre of influential loyalists by placing sympathetic students in the university and military academy while serving as minister of education.

The principle of cross-cutting relationships pertains to the formation of faults and the age of the sequences through which they cut. Faults are younger than the rocks they cut; accordingly, if a fault is found that penetrates some formations but not those on top of it, then the formations that were cut are older than the fault, and the ones that are not cut must be younger than the fault. Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.

What can you say about a fault that penetrates the top rocks but not the lower formations?


Amazon rainforest:

The region is home to about 2.5 million insect species, tens of thousands of plants, and some 2,000 birds and mammals. To date, at least 40,000 plant species, 2,200 fishes, 1,294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region. One in five of all the bird species in the world live in the rainforests of the Amazon, and one in five of the fish species live in Amazonian rivers and streams. Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone.

Some buyers lamented the small size of the first Japanese compacts, and both Toyota and Nissan (then known as Datsun) introduced larger cars such as the Toyota Corona Mark II, the Toyota Cressida, the Mazda 616 and Datsun 810, which added passenger space and amenities such as air conditioning, power steering, AM-FM radios, and even power windows and central locking without increasing the price of the vehicle. A decade after the 1973 oil crisis, Honda, Toyota and Nissan, affected by the 1981 voluntary export restraints, opened US assembly plants and established their luxury divisions (Acura, Lexus and Infiniti, respectively) to distinguish themselves from their mass-market brands.
Try to answer this question if possible (otherwise reply "unanswerable"): Name a luxury division of Toyota.


Read this: The following four timelines show the geologic time scale. The first shows the entire time from the formation of the Earth to the present, but this compresses the most recent eon. Therefore, the second scale shows the most recent eon with an expanded scale. The second scale compresses the most recent era, so the most recent era is expanded in the third scale. Since the Quaternary is a very short period with short epochs, it is further expanded in the fourth scale. The second, third, and fourth timelines are therefore each subsections of their preceding timeline as indicated by asterisks. The Holocene (the latest epoch) is too small to be shown clearly on the third timeline on the right, another reason for expanding the fourth scale. The Pleistocene (P) epoch. Q stands for the Quaternary period.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Which timeline is the most accurate?


The Education Service Contracting scheme of the government provides financial assistance for tuition and other school fees of students turned away from public high schools because of enrollment overflows. The Tuition Fee Supplement is geared to students enrolled in priority courses in post-secondary and non-degree programmes, including vocational and technical courses. The Private Education Student Financial Assistance is made available to underprivileged, but deserving high school graduates, who wish to pursue college/technical education in private colleges and universities.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does the government provide for students turned away from priority courses?


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]
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Where were non-condensing direct-drive locomotives notably used for fast passenger ships?

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

Which regions have temperate climates?

News of the two battles reached England in August. After several months of negotiations, the government of the Duke of Newcastle decided to send an army expedition the following year to dislodge the French. They chose Major General Edward Braddock to lead the expedition. Word of the British military plans leaked to France well before Braddock's departure for North America. In response, King Louis XV dispatched six regiments to New France under the command of Baron Dieskau in 1755. The British, intending to blockade French ports, sent out their fleet in February 1755, but the French fleet had already sailed. Admiral Edward Hawke detached a fast squadron to North America in an attempt to intercept the French.

How did King Louis XV respond to British plans?


Huguenot:

Huguenot numbers peaked near an estimated two million by 1562, concentrated mainly in the southern and central parts of France, about one-eighth the number of French Catholics. As Huguenots gained influence and more openly displayed their faith, Catholic hostility grew, in spite of increasingly liberal political concessions and edicts of toleration from the French crown. A series of religious conflicts followed, known as the Wars of Religion, fought intermittently from 1562 to 1598. The wars finally ended with the granting of the Edict of Nantes, which granted the Huguenots substantial religious, political and military autonomy.

Read this: 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.

Read this: The conflict is known by multiple names. In British America, wars were often named after the sitting British monarch, such as King William's War or Queen Anne's War. As there had already been a King George's War in the 1740s, British colonists named the second war in King George's reign after their opponents, and it became known as the French and Indian War. This traditional name continues as the standard in the United States, but it obscures the fact that Indians fought on both sides of the conflict, and that this was part of the Seven Years' War, a much larger conflict between France and Great Britain. American historians generally use the traditional name or sometimes the Seven Years' War. Other, less frequently used names for the war include the Fourth Intercolonial War and the Great War for the Empire.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What isn't the confusion of the French and Indian war?


Both X.25 and Frame Relay provide connection-oriented operations. But X.25 does it at the network layer of the OSI Model. Frame Relay does it at level two, the data link layer. Another major difference between X.25 and Frame Relay is that X.25 requires a handshake between the communicating parties before any user packets are transmitted. Frame Relay does not define any such handshakes. X.25 does not define any operations inside the packet network. It only operates at the user-network-interface (UNI). Thus, the network provider is free to use any procedure it wishes inside the network. X.25 does specify some limited re-transmission procedures at the UNI, and its link layer protocol (LAPB) provides conventional HDLC-type link management procedures. Frame Relay is a modified version of ISDN's layer two protocol, LAPD and LAPB. As such, its integrity operations pertain only between nodes on a link, not end-to-end. Any retransmissions must be carried out by higher layer protocols. The X.25 UNI protocol is part of the X.25 protocol suite, which consists of the lower three layers of the OSI Model. It was widely used at the UNI for packet switching networks during the 1980s and early 1990s, to provide a standardized interface into and out of packet networks. Some implementations used X.25 within the network as well, but its connection-oriented features made this setup cumbersome and inefficient. Frame relay operates principally at layer two of the OSI Model. However, its address field (the Data Link Connection ID, or DLCI) can be used at the OSI network layer, with a minimum set of procedures. Thus, it rids itself of many X.25 layer 3 encumbrances, but still has the DLCI as an ID beyond a node-to-node layer two link protocol. The simplicity of Frame Relay makes it faster and more efficient than X.25. Because Frame relay is a data link layer protocol, like X.25 it does not define internal network routing operations. For X.25 its packet IDs---the virtual circuit and virtual channel numbers have to be correlated to network addresses. The same is true for Frame Relays DLCI. How this is done is up to the network provider. Frame Relay, by virtue of having no network layer procedures is connection-oriented at layer two, by using the HDLC/LAPD/LAPB Set Asynchronous Balanced Mode (SABM). X.25 connections are typically established for each communication session, but it does have a feature allowing a limited amount of traffic to be passed across the UNI without the connection-oriented handshake. For a while, Frame Relay was used to interconnect LANs across wide area networks. However, X.25 and well as Frame Relay have been supplanted by the Internet Protocol (IP) at the network layer, and the Asynchronous Transfer Mode (ATM) and or versions of Multi-Protocol Label Switching (MPLS) at layer two. A typical configuration is to run IP over ATM or a version of MPLS. <Uyless Black, X.25 and Related Protocols, IEEE Computer Society, 1991> <Uyless Black, Frame Relay Networks, McGraw-Hill, 1998> <Uyless Black, MPLS and Label Switching Networks, Prentice Hall, 2001> < Uyless Black, ATM, Volume I, Prentice Hall, 1995>
