The interpretation of Islam promoted by this funding was the strict, conservative Saudi-based Wahhabism or Salafism. In its harshest form it preached that Muslims should not only "always oppose" infidels "in every way," but "hate them for their religion ... for Allah's sake," that democracy "is responsible for all the horrible wars of the 20th century," that Shia and other non-Wahhabi Muslims were infidels, etc. While this effort has by no means converted all, or even most Muslims to the Wahhabist interpretation of Islam, it has done much to overwhelm more moderate local interpretations, and has set the Saudi-interpretation of Islam as the "gold standard" of religion in minds of some or many Muslims.

The following table gives the largest known primes of the mentioned types. Some of these primes have been found using distributed computing. In 2009, the Great Internet Mersenne Prime Search project was awarded a US$100,000 prize for first discovering a prime with at least 10 million digits. The Electronic Frontier Foundation also offers $150,000 and $250,000 for primes with at least 100 million digits and 1 billion digits, respectively. Some of the largest primes not known to have any particular form (that is, no simple formula such as that of Mersenne primes) have been found by taking a piece of semi-random binary data, converting it to a number n, multiplying it by 256k for some positive integer k, and searching for possible primes within the interval [256kn + 1, 256k(n + 1) − 1].[citation needed]

In the Great Internet Mersenne Prime Search hat was the prize for finding a prime with at least 150,000 digits?


Read this: Around 1800 Richard Trevithick and, separately, Oliver Evans in 1801 introduced engines using high-pressure steam; Trevithick obtained his high-pressure engine patent in 1802. These were much more powerful for a given cylinder size than previous engines and could be made small enough for transport applications. Thereafter, technological developments and improvements in manufacturing techniques (partly brought about by the adoption of the steam engine as a power source) resulted in the design of more efficient engines that could be smaller, faster, or more powerful, depending on the intended application.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Who created an engine using transport applications in 1801?


Read this: Following the utilitarian principle of seeking the greatest good for the greatest number – economic inequality is problematic. A house that provides less utility to a millionaire as a summer home than it would to a homeless family of five, is an example of reduced "distributive efficiency" within society, that decreases marginal utility of wealth and thus the sum total of personal utility. An additional dollar spent by a poor person will go to things providing a great deal of utility to that person, such as basic necessities like food, water, and healthcare; while, an additional dollar spent by a much richer person will very likely go to luxury items providing relatively less utility to that person. Thus, the marginal utility of wealth per person ("the additional dollar") decreases as a person becomes richer. From this standpoint, for any given amount of wealth in society, a society with more equality will have higher aggregate utility. Some studies have found evidence for this theory, noting that in societies where inequality is lower, population-wide satisfaction and happiness tend to be higher.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What does the utilitarian principle seek for the greatest number of people?


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.
Try to answer this question if possible (otherwise reply "unanswerable"): Where can sedimentary rock not be found at the same time?


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


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


The centre-left Australian Labor Party (ALP), the centre-right Liberal Party of Australia, the rural-based National Party of Australia, and the environmentalist Australian Greens are Victoria's main political parties. Traditionally, Labor is strongest in Melbourne's working class western and northern suburbs, and the regional cities of Ballarat, Bendigo and Geelong. The Liberals' main support lies in Melbourne's more affluent eastern and outer suburbs, and some rural and regional centres. The Nationals are strongest in Victoria's North Western and Eastern rural regional areas. The Greens, who won their first lower house seats in 2014, are strongest in inner Melbourne.

The Rankine cycle is the fundamental thermodynamic underpinning of the steam engine. The cycle is an arrangement of components as is typically used for simple power production, and utilizes the phase change of water (boiling water producing steam, condensing exhaust steam, producing liquid water)) to provide a practical heat/power conversion system. The heat is supplied externally to a closed loop with some of the heat added being converted to work and the waste heat being removed in a condenser. The Rankine cycle is used in virtually all steam power production applications. In the 1990s, Rankine steam cycles generated about 90% of all electric power used throughout the world, including virtually all solar, biomass, coal and nuclear power plants. It is named after William John Macquorn Rankine, a Scottish polymath.

Read this: Torque is the rotation equivalent of force in the same way that angle is the rotational equivalent for position, angular velocity for velocity, and angular momentum for momentum. As a consequence of Newton's First Law of Motion, there exists rotational inertia that ensures that all bodies maintain their angular momentum unless acted upon by an unbalanced torque. Likewise, Newton's Second Law of Motion can be used to derive an analogous equation for the instantaneous angular acceleration of the rigid body:
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): To calculate instant angular acceleration of a rigid body what would you use?


Among the most important classes of organic compounds that contain oxygen are (where "R" is an organic group): alcohols (R-OH); ethers (R-O-R); ketones (R-CO-R); aldehydes (R-CO-H); carboxylic acids (R-COOH); esters (R-COO-R); acid anhydrides (R-CO-O-CO-R); and amides (R-C(O)-NR

An oscillating cylinder steam engine is a variant of the simple expansion steam engine which does not require valves to direct steam into and out of the cylinder. Instead of valves, the entire cylinder rocks, or oscillates, such that one or more holes in the cylinder line up with holes in a fixed port face or in the pivot mounting (trunnion). These engines are mainly used in toys and models, because of their simplicity, but have also been used in full size working engines, mainly on ships where their compactness is valued.[citation needed]

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

What organization was responsible for setting up the IPCC?

It is possible to use a mechanism based on a pistonless rotary engine such as the Wankel engine in place of the cylinders and valve gear of a conventional reciprocating steam engine. Many such engines have been designed, from the time of James Watt to the present day, but relatively few were actually built and even fewer went into quantity production; see link at bottom of article for more details. The major problem is the difficulty of sealing the rotors to make them steam-tight in the face of wear and thermal expansion; the resulting leakage made them very inefficient. Lack of expansive working, or any means of control of the cutoff is also a serious problem with many such designs.[citation needed]

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.

Rhine:

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.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Where does the Rhine make a distinctive turn to the south?


The Chinese medical tradition of the Yuan had "Four Great Schools" that the Yuan inherited from the Jin dynasty. All four schools were based on the same intellectual foundation, but advocated different theoretical approaches toward medicine. Under the Mongols, the practice of Chinese medicine spread to other parts of the empire. Chinese physicians were brought along military campaigns by the Mongols as they expanded towards the west. Chinese medical techniques such as acupuncture, moxibustion, pulse diagnosis, and various herbal drugs and elixirs were transmitted westward to the Middle East and the rest of the empire. Several medical advances were made in the Yuan period. The physician Wei Yilin (1277–1347) invented a suspension method for reducing dislocated joints, which he performed using anesthetics. The Mongol physician Hu Sihui described the importance of a healthy diet in a 1330 medical treatise.

The smaller the economic inequality, the more waste and pollution is created, resulting in many cases, in more environmental degradation. This can be explained by the fact that as the poor people in the society become more wealthy, it increases their yearly carbon emissions. This relation is expressed by the Environmental Kuznets Curve (EKC).[not in citation given] It should be noted here however that in certain cases, with great economic inequality, there is nonetheless not more waste and pollution created as the waste/pollution is cleaned up better afterwards (water treatment, filtering, ...).... Also note that the whole of the increase in environmental degradation is the result of the increase of emissions per person being multiplied by a multiplier. If there were fewer people however, this multiplier would be lower, and thus the amount of environmental degradation would be lower as well. As such, the current high level of population has a large impact on this as well. If (as WWF argued), population levels would start to drop to a sustainable level (1/3 of current levels, so about 2 billion people), human inequality can be addressed/corrected, while still not resulting in an increase of environmental damage.
Try to answer this question if possible (otherwise reply "unanswerable"): When political inequality is smaller, more waste and pollution is?

One computer model of future climate change caused by greenhouse gas emissions shows that the Amazon rainforest could become unsustainable under conditions of severely reduced rainfall and increased temperatures, leading to an almost complete loss of rainforest cover in the basin by 2100. However, simulations of Amazon basin climate change across many different models are not consistent in their estimation of any rainfall response, ranging from weak increases to strong decreases. The result indicates that the rainforest could be threatened though the 21st century by climate change in addition to deforestation.

What are the main threats facing the Amazon rainforest in the current century?


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

Britain's imperialist ambitions can be seen as early as the sixteenth century. In 1599 the British East India Company was established and was chartered by Queen Elizabeth in the following year. With the establishment of trading posts in India, the British were able to maintain strength relative to others empires such as the Portuguese who already had set up trading posts in India. In 1767 political activity caused exploitation of the East India Company causing the plundering of the local economy, almost bringing the company into bankruptcy.

After the 1940s, the Gothic style on campus began to give way to modern styles. In 1955, Eero Saarinen was contracted to develop a second master plan, which led to the construction of buildings both north and south of the Midway, including the Laird Bell Law Quadrangle (a complex designed by Saarinen); a series of arts buildings; a building designed by Ludwig Mies van der Rohe for the university's School of Social Service Administration;, a building which is to become the home of the Harris School of Public Policy Studies by Edward Durrell Stone, and the Regenstein Library, the largest building on campus, a brutalist structure designed by Walter Netsch of the Chicago firm Skidmore, Owings & Merrill. Another master plan, designed in 1999 and updated in 2004, produced the Gerald Ratner Athletics Center (2003), the Max Palevsky Residential Commons (2001), South Campus Residence Hall and dining commons (2009), a new children's hospital, and other construction, expansions, and restorations. In 2011, the university completed the glass dome-shaped Joe and Rika Mansueto Library, which provides a grand reading room for the university library and prevents the need for an off-campus book depository.

Oxygen toxicity to the lungs and central nervous system can also occur in deep scuba diving and surface supplied diving. Prolonged breathing of an air mixture with an O
2 partial pressure more than 60 kPa can eventually lead to permanent pulmonary fibrosis. Exposure to a O
2 partial pressures greater than 160 kPa (about 1.6 atm) may lead to convulsions (normally fatal for divers). Acute oxygen toxicity (causing seizures, its most feared effect for divers) can occur by breathing an air mixture with 21% O
2 at 66 m or more of depth; the same thing can occur by breathing 100% O
2 at only 6 m.

The fourth Yuan emperor, Buyantu Khan (Ayurbarwada), was a competent emperor. He was the first Yuan emperor to actively support and adopt mainstream Chinese culture after the reign of Kublai, to the discontent of some Mongol elite. He had been mentored by Li Meng, a Confucian academic. He made many reforms, including the liquidation of the Department of State Affairs (Chinese: 尚書省), which resulted in the execution of five of the highest-ranking officials. Starting in 1313 the traditional imperial examinations were reintroduced for prospective officials, testing their knowledge on significant historical works. Also, he codified much of the law, as well as publishing or translating a number of Chinese books and works.

When did Buyantu stop testing potential government employees?


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.
What are those with lower incomes less likely to have in order to prepare for the future? (If the question is unanswerable, say "unanswerable")


Packet switching:

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

Most Platyctenida have oval bodies that are flattened in the oral-aboral direction, with a pair of tentilla-bearing tentacles on the aboral surface. They cling to and creep on surfaces by everting the pharynx and using it as a muscular "foot". All but one of the known platyctenid species lack comb-rows. Platyctenids are usually cryptically colored, live on rocks, algae, or the body surfaces of other invertebrates, and are often revealed by their long tentacles with many sidebranches, seen streaming off the back of the ctenophore into the current.

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.

Steam engine:

It is a logical extension of the compound engine (described above) to split the expansion into yet more stages to increase efficiency. The result is the multiple expansion engine. Such engines use either three or four expansion stages and are known as triple and quadruple expansion engines respectively. These engines use a series of cylinders of progressively increasing diameter. These cylinders are designed to divide the work into equal shares for each expansion stage. As with the double expansion engine, if space is at a premium, then two smaller cylinders may be used for the low-pressure stage. Multiple expansion engines typically had the cylinders arranged inline, but various other formations were used. In the late 19th century, the Yarrow-Schlick-Tweedy balancing 'system' was used on some marine triple expansion engines. Y-S-T engines divided the low-pressure expansion stages between two cylinders, one at each end of the engine. This allowed the crankshaft to be better balanced, resulting in a smoother, faster-responding engine which ran with less vibration. This made the 4-cylinder triple-expansion engine popular with large passenger liners (such as the Olympic class), but this was ultimately replaced by the virtually vibration-free turbine engine.[citation needed]

The basic unit of territorial division in Poland is a commune (gmina). A city is also a commune – but with the city charter. Both cities and communes are governed by a mayor – but in the communes the mayor is vogt (wójt in Polish), however in the cities – burmistrz. Some bigger cities obtain the entitlements, i.e. tasks and privileges, which are possessed by the units of the second level of the territorial division – counties or powiats. An example of such entitlement is a car registration: a gmina cannot register cars, this is a powiat's task (i.e. a registration number depends on what powiat a car had been registered, not gmina). In this case we say about city county or powiat grodzki. Such cities are for example Lublin, Kraków, Gdańsk, Poznań. In Warsaw, its districts additionally have some of powiat's entitlements – like already mentioned car registration. For example, the district Wola has its own evidence and the district Ursynów – its own (and the cars from Wola have another type of registration number than these from Ursynów). But for instance the districts in Kraków do not have entitlements of powiat, so the registration numbers in Kraków are of the same type for all districts.

What we now call gravity was not identified as a universal force until the work of Isaac Newton. Before Newton, the tendency for objects to fall towards the Earth was not understood to be related to the motions of celestial objects. Galileo was instrumental in describing the characteristics of falling objects by determining that the acceleration of every object in free-fall was constant and independent of the mass of the object. Today, this acceleration due to gravity towards the surface of the Earth is usually designated as  and has a magnitude of about 9.81 meters per second squared (this measurement is taken from sea level and may vary depending on location), and points toward the center of the Earth. This observation means that the force of gravity on an object at the Earth's surface is directly proportional to the object's mass. Thus an object that has a mass of  will experience a force:

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.

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

Tamara de Lempicka was a famous artist born in Warsaw. She was born Maria Górska in Warsaw to wealthy parents and in 1916 married a Polish lawyer Tadeusz Łempicki. Better than anyone else she represented the Art Deco style in painting and art. Nathan Alterman, the Israeli poet, was born in Warsaw, as was Moshe Vilenski, the Israeli composer, lyricist, and pianist, who studied music at the Warsaw Conservatory. Warsaw was the beloved city of Isaac Bashevis Singer, which he described in many of his novels: Warsaw has just now been destroyed. No one will ever see the Warsaw I knew. Let me just write about it. Let this Warsaw not disappear forever, he commented.

Parliamentary time is also set aside for question periods in the debating chamber. A "General Question Time" takes place on a Thursday between 11:40 a.m. and 12 p.m. where members can direct questions to any member of the Scottish Government. At 2.30pm, a 40-minute long themed "Question Time" takes place, where members can ask questions of ministers in departments that are selected for questioning that sitting day, such as health and justice or education and transport. Between 12 p.m. and 12:30 p.m. on Thursdays, when Parliament is sitting, First Minister's Question Time takes place. This gives members an opportunity to question the First Minister directly on issues under their jurisdiction. Opposition leaders ask a general question of the First Minister and then supplementary questions. Such a practice enables a "lead-in" to the questioner, who then uses their supplementary question to ask the First Minister any issue. The four general questions available to opposition leaders are:

Oxygen, as a supposed mild euphoric, has a history of recreational use in oxygen bars and in sports. Oxygen bars are establishments, found in Japan, California, and Las Vegas, Nevada since the late 1990s that offer higher than normal O
2 exposure for a fee. Professional athletes, especially in American football, also sometimes go off field between plays to wear oxygen masks in order to get a "boost" in performance. The pharmacological effect is doubtful; a placebo effect is a more likely explanation. Available studies support a performance boost from enriched O
2 mixtures only if they are breathed during aerobic exercise.

After each election to the Scottish Parliament, at the beginning of each parliamentary session, Parliament elects one MSP to serve as Presiding Officer, the equivalent of the speaker (currently Tricia Marwick), and two MSPs to serve as deputies (currently Elaine Smith and John Scott). The Presiding Officer and deputies are elected by a secret ballot of the 129 MSPs, which is the only secret ballot conducted in the Scottish Parliament. Principally, the role of the Presiding Officer is to chair chamber proceedings and the Scottish Parliamentary Corporate Body. When chairing meetings of the Parliament, the Presiding Officer and his/her deputies must be politically impartial. During debates, the Presiding Officer (or the deputy) is assisted by the parliamentary clerks, who give advice on how to interpret the standing orders that govern the proceedings of meetings. A vote clerk sits in front of the Presiding Officer and operates the electronic voting equipment and chamber clocks.

Read this: In this dioxygen, the two oxygen atoms are chemically bonded to each other. The bond can be variously described based on level of theory, but is reasonably and simply described as a covalent double bond that results from the filling of molecular orbitals formed from the atomic orbitals of the individual oxygen atoms, the filling of which results in a bond order of two. More specifically, the double bond is the result of sequential, low-to-high energy, or Aufbau, filling of orbitals, and the resulting cancellation of contributions from the 2s electrons, after sequential filling of the low σ and σ* orbitals; σ overlap of the two atomic 2p orbitals that lie along the O-O molecular axis and π overlap of two pairs of atomic 2p orbitals perpendicular to the O-O molecular axis, and then cancellation of contributions from the remaining two of the six 2p electrons after their partial filling of the lowest π and π* orbitals.

An important decision for civil disobedients is whether or not to plead guilty. There is much debate on this point, as some believe that it is a civil disobedient's duty to submit to the punishment prescribed by law, while others believe that defending oneself in court will increase the possibility of changing the unjust law. It has also been argued that either choice is compatible with the spirit of civil disobedience. ACT-UP's Civil Disobedience Training handbook states that a civil disobedient who pleads guilty is essentially stating, "Yes, I committed the act of which you accuse me. I don't deny it; in fact, I am proud of it. I feel I did the right thing by violating this particular law; I am guilty as charged," but that pleading not guilty sends a message of, "Guilt implies wrong-doing. I feel I have done no wrong. I may have violated some specific laws, but I am guilty of doing no wrong. I therefore plead not guilty." A plea of no contest is sometimes regarded as a compromise between the two. One defendant accused of illegally protesting nuclear power, when asked to enter his plea, stated, "I plead for the beauty that surrounds us"; this is known as a "creative plea," and will usually be interpreted as a plea of not guilty.

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.

As of February 2017, how many numbers has Goldbach's conjecture been proven to?

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

How much did the population of Victoria increase in ten years after the discovery of gold?

In World War II, it was recognised that the Rhine would present a formidable natural obstacle to the invasion of Germany, by the Western Allies. The Rhine bridge at Arnhem, immortalized in the book, A Bridge Too Far and the film, was a central focus of the battle for Arnhem, during the failed Operation Market Garden of September 1944. The bridges at Nijmegen, over the Waal distributary of the Rhine, were also an objective of Operation Market Garden. In a separate operation, the Ludendorff Bridge, crossing the Rhine at Remagen, became famous, when U.S. forces were able to capture it intact – much to their own surprise – after the Germans failed to demolish it. This also became the subject of a film, The Bridge at Remagen. Seven Days to the River Rhine was a Warsaw Pact war plan for an invasion of Western Europe during the Cold War.

Eventually, the Normans merged with the natives, combining languages and traditions. In the course of the Hundred Years' War, the Norman aristocracy often identified themselves as English. The Anglo-Norman language became distinct from the Latin language, something that was the subject of some humour by Geoffrey Chaucer. The Anglo-Norman language was eventually absorbed into the Anglo-Saxon language of their subjects (see Old English) and influenced it, helping (along with the Norse language of the earlier Anglo-Norse settlers and the Latin used by the church) in the development of Middle English. It in turn evolved into Modern English.

In the 1890s, the University of Chicago, fearful that its vast resources would injure smaller schools by drawing away good students, affiliated with several regional colleges and universities: Des Moines College, Kalamazoo College, Butler University, and Stetson University. In 1896, the university affiliated with Shimer College in Mount Carroll, Illinois. Under the terms of the affiliation, the schools were required to have courses of study comparable to those at the university, to notify the university early of any contemplated faculty appointments or dismissals, to make no faculty appointment without the university's approval, and to send copies of examinations for suggestions. The University of Chicago agreed to confer a degree on any graduating senior from an affiliated school who made a grade of A for all four years, and on any other graduate who took twelve weeks additional study at the University of Chicago. A student or faculty member of an affiliated school was entitled to free tuition at the University of Chicago, and Chicago students were eligible to attend an affiliated school on the same terms and receive credit for their work. The University of Chicago also agreed to provide affiliated schools with books and scientific apparatus and supplies at cost; special instructors and lecturers without cost except travel expenses; and a copy of every book and journal published by the University of Chicago Press at no cost. The agreement provided that either party could terminate the affiliation on proper notice. Several University of Chicago professors disliked the program, as it involved uncompensated additional labor on their part, and they believed it cheapened the academic reputation of the university. The program passed into history by 1910.

Sir Charles Lyell first published his famous book, Principles of Geology, in 1830. This book, which influenced the thought of Charles Darwin, successfully promoted the doctrine of uniformitarianism. This theory states that slow geological processes have occurred throughout the Earth's history and are still occurring today. In contrast, catastrophism is the theory that Earth's features formed in single, catastrophic events and remained unchanged thereafter. Though Hutton believed in uniformitarianism, the idea was not widely accepted at the time.

Which theory states that slow geological processes are still occurring today, and have occurred throughout Earth's history?


Read this: In particular, this norm gets smaller when a number is multiplied by p, in sharp contrast to the usual absolute value (also referred to as the infinite prime). While completing Q (roughly, filling the gaps) with respect to the absolute value yields the field of real numbers, completing with respect to the p-adic norm |−|p yields the field of p-adic numbers. These are essentially all possible ways to complete Q, by Ostrowski's theorem. Certain arithmetic questions related to Q or more general global fields may be transferred back and forth to the completed (or local) fields. This local-global principle again underlines the importance of primes to number theory.

Read this: 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.

A construction project is a complex net of contracts and other legal obligations, each of which all parties must carefully consider. A contract is the exchange of a set of obligations between two or more parties, but it is not so simple a matter as trying to get the other side to agree to as much as possible in exchange for as little as possible. The time element in construction means that a delay costs money, and in cases of bottlenecks, the delay can be extremely expensive. Thus, the contracts must be designed to ensure that each side is capable of performing the obligations set out. Contracts that set out clear expectations and clear paths to accomplishing those expectations are far more likely to result in the project flowing smoothly, whereas poorly drafted contracts lead to confusion and collapse.

Sometimes the prosecution proposes a plea bargain to civil disobedients, as in the case of the Camden 28, in which the defendants were offered an opportunity to plead guilty to one misdemeanor count and receive no jail time. In some mass arrest situations, the activists decide to use solidarity tactics to secure the same plea bargain for everyone. But some activists have opted to enter a blind plea, pleading guilty without any plea agreement in place. Mohandas Gandhi pleaded guilty and told the court, "I am here to . . . submit cheerfully to the highest penalty that can be inflicted upon me for what in law is a deliberate crime and what appears to me to be the highest duty of a citizen."

Read this: Politically, the system of government created by Kublai Khan was the product of a compromise between Mongolian patrimonial feudalism and the traditional Chinese autocratic-bureaucratic system. Nevertheless, socially the educated Chinese elite were in general not given the degree of esteem that they had been accorded previously under native Chinese dynasties. Although the traditional Chinese elite were not given their share of power, the Mongols and the Semuren (various allied groups from Central Asia and the western end of the empire) largely remained strangers to the mainstream Chinese culture, and this dichotomy gave the Yuan regime a somewhat strong "colonial" coloration. The unequal treatment is possibly due to the fear of transferring power to the ethnic Chinese under their rule. The Mongols and Semuren were given certain advantages in the dynasty, and this would last even after the restoration of the imperial examination in the early 14th century. In general there were very few North Chinese or Southerners reaching the highest-post in the government compared with the possibility that Persians did so in the Ilkhanate. Later the Yongle Emperor of the Ming dynasty also mentioned the discrimination that existed during the Yuan dynasty. In response to an objection against the use of "barbarians" in his government, the Yongle Emperor answered: "... Discrimination was used by the Mongols during the Yuan dynasty, who employed only "Mongols and Tartars" and discarded northern and southern Chinese and this was precisely the cause that brought disaster upon them".

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.

Western medicine was also practiced in China by the Nestorian Christians of the Yuan court, where it was sometimes labeled as huihui or Muslim medicine. The Nestorian physician Jesus the Interpreter founded the Office of Western Medicine in 1263 during the reign of Kublai. Huihui doctors staffed at two imperial hospitals were responsible for treating the imperial family and members of the court. Chinese physicians opposed Western medicine because its humoral system contradicted the yin-yang and wuxing philosophy underlying traditional Chinese medicine. No Chinese translation of Western medical works is known, but it is possible that the Chinese had access to Avicenna's The Canon of Medicine.

The concept of prime number is so important that it has been generalized in different ways in various branches of mathematics. Generally, "prime" indicates minimality or indecomposability, in an appropriate sense. For example, the prime field is the smallest subfield of a field F containing both 0 and 1. It is either Q or the finite field with p elements, whence the name. Often a second, additional meaning is intended by using the word prime, namely that any object can be, essentially uniquely, decomposed into its prime components. For example, in knot theory, a prime knot is a knot that is indecomposable in the sense that it cannot be written as the knot sum of two nontrivial knots. Any knot can be uniquely expressed as a connected sum of prime knots. Prime models and prime 3-manifolds are other examples of this type.

How can any knot be distinctively indicated?


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 French Protestant Church of London was established by Royal Charter in 1550. It is now located at Soho Square. Huguenot refugees flocked to Shoreditch, London. They established a major weaving industry in and around Spitalfields (see Petticoat Lane and the Tenterground) in East London. In Wandsworth, their gardening skills benefited the Battersea market gardens. The Old Truman Brewery, then known as the Black Eagle Brewery, was founded in 1724. The flight of Huguenot refugees from Tours, France drew off most of the workers of its great silk mills which they had built.[citation needed] Some of these immigrants moved to Norwich, which had accommodated an earlier settlement of Walloon weavers. The French added to the existing immigrant population, then comprising about a third of the population of the city.

In 2010 a salary survey revealed the differences in remuneration between different roles, sectors and locations in the construction and built environment industry. The results showed that areas of particularly strong growth in the construction industry, such as the Middle East, yield higher average salaries than in the UK for example. The average earning for a professional in the construction industry in the Middle East, across all sectors, job types and levels of experience, is £42,090, compared to £26,719 in the UK. This trend is not necessarily due to the fact that more affluent roles are available, however, as architects with 14 or more years experience working in the Middle East earn on average £43,389 per annum, compared to £40,000 in the UK. Some construction workers in the US/Canada have made more than $100,000 annually, depending on their trade.

The Rhine (Romansh: Rein, German: Rhein, French: le Rhin, Dutch: Rijn) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Swiss-Austrian, Swiss-Liechtenstein border, Swiss-German and then the Franco-German border, then flows through the Rhineland and eventually empties into the North Sea in the Netherlands. The biggest city on the river Rhine is Cologne, Germany with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about 1,230 km (760 mi),[note 2][note 1] with an average discharge of about 2,900 m3/s (100,000 cu ft/s).

In the Philippines, the private sector has been a major provider of educational services, accounting for about 7.5% of primary enrollment, 32% of secondary enrollment and about 80% of tertiary enrollment. Private schools have proven to be efficient in resource utilization. Per unit costs in private schools are generally lower when compared to public schools. This situation is more evident at the tertiary level. Government regulations have given private education more flexibility and autonomy in recent years, notably by lifting the moratorium on applications for new courses, new schools and conversions, by liberalizing tuition fee policy for private schools, by replacing values education for third and fourth years with English, mathematics and natural science at the option of the school, and by issuing the revised Manual of Regulations for Private Schools in August 1992.

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

Answer this question, if possible (if impossible, reply "unanswerable"): Why did the 5th president of the university decide to get rid of the football program?


Religiously affiliated and denominational schools form a subcategory of private schools. Some such schools teach religious education, together with the usual academic subjects to impress their particular faith's beliefs and traditions in the students who attend. Others use the denomination as more of a general label to describe on what the founders based their belief, while still maintaining a fine distinction between academics and religion. They include parochial schools, a term which is often used to denote Roman Catholic schools. Other religious groups represented in the K-12 private education sector include Protestants, Jews, Muslims and the Orthodox Christians.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why were Roman Catholic schools founded?


The adoption of compounding was common for industrial units, for road engines and almost universal for marine engines after 1880; it was not universally popular in railway locomotives where it was often perceived as complicated. This is partly due to the harsh railway operating environment and limited space afforded by the loading gauge (particularly in Britain, where compounding was never common and not employed after 1930). However, although never in the majority, it was popular in many other countries.
Along with marine engines and industrial units, in what machines were marine locomotives popular? (If the question is unanswerable, say "unanswerable")

Many known complexity classes are suspected to be unequal, but this has not been proved. For instance P ⊆ NP ⊆ PP ⊆ PSPACE, but it is possible that P = PSPACE. If P is not equal to NP, then P is not equal to PSPACE either. Since there are many known complexity classes between P and PSPACE, such as RP, BPP, PP, BQP, MA, PH, etc., it is possible that all these complexity classes collapse to one class. Proving that any of these classes are unequal would be a major breakthrough in complexity theory.

What is impossible for the complexity classes RP, BPP, PP, BQP, MA, and PH?


Structural geologists use microscopic analysis of oriented thin sections of geologic samples to observe the fabric within the rocks which gives information about strain within the crystalline structure of the rocks. They also plot and combine measurements of geological structures in order to better understand the orientations of faults and folds in order to reconstruct the history of rock deformation in the area. In addition, they perform analog and numerical experiments of rock deformation in large and small settings.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How do structural geologists observe the fabric within the rocks?


Warsaw, especially its city centre (Śródmieście), is home not only to many national institutions and government agencies, but also to many domestic and international companies. In 2006, 304,016 companies were registered in the city. Warsaw's ever-growing business community has been noticed globally, regionally, and nationally. MasterCard Emerging Market Index has noted Warsaw's economic strength and commercial center. Moreover, Warsaw was ranked as the 7th greatest emerging market. Foreign investors' financial participation in the city's development was estimated in 2002 at over 650 million euro. Warsaw produces 12% of Poland's national income, which in 2008 was 305.1% of the Polish average, per capita (or 160% of the European Union average). The GDP per capita in Warsaw amounted to PLN 94 000 in 2008 (c. EUR 23 800, USD 33 000). Total nominal GDP of the city in 2010 amounted to 191.766 billion PLN, 111696 PLN per capita, which was 301,1 % of Polish average. Warsaw leads the region of East-Central Europe in foreign investment and in 2006, GDP growth met expectations with a level of 6.1%. It also has one of the fastest growing economies, with GDP growth at 6.5 percent in 2007 and 6.1 percent in the first quarter of 2008.

Answer this question, if possible (if impossible, reply "unanswerable"): How much of Poland's national income does Srodmiescie produce?


Warsaw is located on two main geomorphologic formations: the plain moraine plateau and the Vistula Valley with its asymmetrical pattern of different terraces. The Vistula River is the specific axis of Warsaw, which divides the city into two parts, left and right. The left one is situated both on the moraine plateau (10 to 25 m (32.8 to 82.0 ft) above Vistula level) and on the Vistula terraces (max. 6.5 m (21.3 ft) above Vistula level). The significant element of the relief, in this part of Warsaw, is the edge of moraine plateau called Warsaw Escarpment. It is 20 to 25 m (65.6 to 82.0 ft) high in the Old Town and Central district and about 10 m (32.8 ft) in the north and south of Warsaw. It goes through the city and plays an important role as a landmark.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the axis of Vistula which divides it into two parts?

Since its invention in 1269, the 'Phags-pa script, a unified script for spelling Mongolian, Tibetan, and Chinese languages, was preserved in the court until the end of the dynasty. Most of the Emperors could not master written Chinese, but they could generally converse well in the language. The Mongol custom of long standing quda/marriage alliance with Mongol clans, the Onggirat, and the Ikeres, kept the imperial blood purely Mongol until the reign of Tugh Temur, whose mother was a Tangut concubine. The Mongol Emperors had built large palaces and pavilions, but some still continued to live as nomads at times. Nevertheless, a few other Yuan emperors actively sponsored cultural activities; an example is Tugh Temur (Emperor Wenzong), who wrote poetry, painted, read Chinese classical texts, and ordered the compilation of books.

Answer this question, if possible (if impossible, reply "unanswerable"): Which languages used the Phags-pa script?

Charles W. Eliot, president 1869–1909, eliminated the favored position of Christianity from the curriculum while opening it to student self-direction. While Eliot was the most crucial figure in the secularization of American higher education, he was motivated not by a desire to secularize education, but by Transcendentalist Unitarian convictions. Derived from William Ellery Channing and Ralph Waldo Emerson, these convictions were focused on the dignity and worth of human nature, the right and ability of each person to perceive truth, and the indwelling God in each person.

What president eliminated the Christian position in the curriculum?


Read this: Following the conquest of Dali in 1253, the former ruling Duan dynasty were appointed as governors-general, recognized as imperial officials by the Yuan, Ming, and Qing-era governments, principally in the province of Yunnan. Succession for the Yuan dynasty, however, was an intractable problem, later causing much strife and internal struggle. This emerged as early as the end of Kublai's reign. Kublai originally named his eldest son, Zhenjin, as the Crown Prince, but he died before Kublai in 1285. Thus, Zhenjin's third son, with the support of his mother Kökejin and the minister Bayan, succeeded the throne and ruled as Temür Khan, or Emperor Chengzong, from 1294 to 1307. Temür Khan decided to maintain and continue much of the work begun by his grandfather. He also made peace with the western Mongol khanates as well as neighboring countries such as Vietnam, which recognized his nominal suzerainty and paid tributes for a few decades. However, the corruption in the Yuan dynasty began during the reign of Temür Khan.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"):  Who had Kublai wanted to precede him?


Read this: As of 2012, quality private schools in the United States charged substantial tuition, close to $40,000 annually for day schools in New York City, and nearly $50,000 for boarding schools. However, tuition did not cover operating expenses, particularly at boarding schools. The leading schools such as the Groton School had substantial endowments running to hundreds of millions of dollars supplemented by fundraising drives. Boarding schools with a reputation for quality in the United States have a student body drawn from throughout the country, indeed the globe, and a list of applicants which far exceeds their capacity.

In addition to arguing that the rat population was insufficient to account for a bubonic plague pandemic, sceptics of the bubonic plague theory point out that the symptoms of the Black Death are not unique (and arguably in some accounts may differ from bubonic plague); that transference via fleas in goods was likely to be of marginal significance; and that the DNA results may be flawed and might not have been repeated elsewhere, despite extensive samples from other mass graves. Other arguments include the lack of accounts of the death of rats before outbreaks of plague between the 14th and 17th centuries; temperatures that are too cold in northern Europe for the survival of fleas; that, despite primitive transport systems, the spread of the Black Death was much faster than that of modern bubonic plague; that mortality rates of the Black Death appear to be very high; that, while modern bubonic plague is largely endemic as a rural disease, the Black Death indiscriminately struck urban and rural areas; and that the pattern of the Black Death, with major outbreaks in the same areas separated by 5 to 15 years, differs from modern bubonic plague—which often becomes endemic for decades with annual flare-ups.

Why might rats not be responsible for the plague?


Read this: To further highlight the difference between a problem and an instance, consider the following instance of the decision version of the traveling salesman problem: Is there a route of at most 2000 kilometres passing through all of Germany's 15 largest cities? The quantitative answer to this particular problem instance is of little use for solving other instances of the problem, such as asking for a round trip through all sites in Milan whose total length is at most 10 km. For this reason, complexity theory addresses computational problems and not particular problem instances.

The adaptive immune system evolved in early vertebrates and allows for a stronger immune response as well as immunological memory, where each pathogen is "remembered" by a signature antigen. The adaptive immune response is antigen-specific and requires the recognition of specific "non-self" antigens during a process called antigen presentation. Antigen specificity allows for the generation of responses that are tailored to specific pathogens or pathogen-infected cells. The ability to mount these tailored responses is maintained in the body by "memory cells". Should a pathogen infect the body more than once, these specific memory cells are used to quickly eliminate it.

Warsaw's name in the Polish language is Warszawa, approximately /vɑːrˈʃɑːvə/ (also formerly spelled Warszewa and Warszowa), meaning "belonging to Warsz", Warsz being a shortened form of the masculine name of Slavic origin Warcisław; see also etymology of Wrocław. Folk etymology attributes the city name to a fisherman, Wars, and his wife, Sawa. According to legend, Sawa was a mermaid living in the Vistula River with whom Wars fell in love. In actuality, Warsz was a 12th/13th-century nobleman who owned a village located at the modern-day site of Mariensztat neighbourhood. See also the Vršovci family which had escaped to Poland. The official city name in full is miasto stołeczne Warszawa (English: "The Capital City of Warsaw"). A native or resident of Warsaw is known as a Varsovian – in Polish warszawiak (male), warszawianka (female), warszawiacy (plural).

In the early years, many Huguenots also settled in the area of present-day Charleston, South Carolina. In 1685, Rev. Elie Prioleau from the town of Pons in France, was among the first to settle there. He became pastor of the first Huguenot church in North America in that city. After the Revocation of the Edict of Nantes in 1685, several Huguenot families of Norman and Carolingian nobility and descent, including Edmund Bohun of Suffolk England from the Humphrey de Bohun line of French royalty descended from Charlemagne, Jean Postell of Dieppe France, Alexander Pepin, Antoine Poitevin of Orsement France, and Jacques de Bordeaux of Grenoble, immigrated to the Charleston Orange district. They were very successful at marriage and property speculation. After petitioning the British Crown in 1697 for the right to own land in the Baronies, they prospered as slave owners on the Cooper, Ashepoo, Ashley and Santee River plantations they purchased from the British Landgrave Edmund Bellinger. Some of their descendants moved into the Deep South and Texas, where they developed new plantations.

French and Indian War:

Governor Robert Dinwiddie of Virginia was an investor in the Ohio Company, which stood to lose money if the French held their claim. To counter the French military presence in Ohio, in October 1753 Dinwiddie ordered the 21-year-old Major George Washington (whose brother was another Ohio Company investor) of the Virginia Regiment to warn the French to leave Virginia territory. Washington left with a small party, picking up along the way Jacob Van Braam as an interpreter; Christopher Gist, a company surveyor working in the area; and a few Mingo led by Tanaghrisson. On December 12, Washington and his men reached Fort Le Boeuf.

The Mongol rulers patronized the Yuan printing industry. Chinese printing technology was transferred to the Mongols through Kingdom of Qocho and Tibetan intermediaries. Some Yuan documents such as Wang Zhen's Nong Shu were printed with earthenware movable type, a technology invented in the 12th century. However, most published works were still produced through traditional block printing techniques. The publication of a Taoist text inscribed with the name of Töregene Khatun, Ögedei's wife, is one of the first printed works sponsored by the Mongols. In 1273, the Mongols created the Imperial Library Directorate, a government-sponsored printing office. The Yuan government established centers for printing throughout China. Local schools and government agencies were funded to support the publishing of books.

Immune system:

Within the genitourinary and gastrointestinal tracts, commensal flora serve as biological barriers by competing with pathogenic bacteria for food and space and, in some cases, by changing the conditions in their environment, such as pH or available iron. This reduces the probability that pathogens will reach sufficient numbers to cause illness. However, since most antibiotics non-specifically target bacteria and do not affect fungi, oral antibiotics can lead to an "overgrowth" of fungi and cause conditions such as a vaginal candidiasis (a yeast infection). There is good evidence that re-introduction of probiotic flora, such as pure cultures of the lactobacilli normally found in unpasteurized yogurt, helps restore a healthy balance of microbial populations in intestinal infections in children and encouraging preliminary data in studies on bacterial gastroenteritis, inflammatory bowel diseases, urinary tract infection and post-surgical infections.

The owner produces a list of requirements for a project, giving an overall view of the project's goals. Several D&B contractors present different ideas about how to accomplish these goals. The owner selects the ideas he or she likes best and hires the appropriate contractor. Often, it is not just one contractor, but a consortium of several contractors working together. Once these have been hired, they begin building the first phase of the project. As they build phase 1, they design phase 2. This is in contrast to a design-bid-build contract, where the project is completely designed by the owner, then bid on, then completed.

Throughout its existence, Warsaw has been a multi-cultural city. According to the 1901 census, out of 711,988 inhabitants 56.2% were Catholics, 35.7% Jews, 5% Greek orthodox Christians and 2.8% Protestants. Eight years later, in 1909, there were 281,754 Jews (36.9%), 18,189 Protestants (2.4%) and 2,818 Mariavites (0.4%). This led to construction of hundreds of places of religious worship in all parts of the town. Most of them were destroyed in the aftermath of the Warsaw Uprising of 1944. After the war, the new communist authorities of Poland discouraged church construction and only a small number were rebuilt.
Try to answer this question if possible (otherwise reply "unanswerable"): When were most of the places of religious worship destroyed in Poland?


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