Immune system:

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.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Antigen specificity  allows responses that are specific to certain types of what?


In humans, this response is activated by complement binding to antibodies that have attached to these microbes or the binding of complement proteins to carbohydrates on the surfaces of microbes. This recognition signal triggers a rapid killing response. The speed of the response is a result of signal amplification that occurs following sequential proteolytic activation of complement molecules, which are also proteases. After complement proteins initially bind to the microbe, they activate their protease activity, which in turn activates other complement proteases, and so on. This produces a catalytic cascade that amplifies the initial signal by controlled positive feedback. The cascade results in the production of peptides that attract immune cells, increase vascular permeability, and opsonize (coat) the surface of a pathogen, marking it for destruction. This deposition of complement can also kill cells directly by disrupting their plasma membrane.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Complement proteins bind to what kind of molecules on the surface of microbes in order to elicit an immune response?


Read this: The Royal Geographical Society of London and other geographical societies in Europe had great influence and were able to fund travelers who would come back with tales of their discoveries. These societies also served as a space for travellers to share these stories.Political geographers such as Friedrich Ratzel of Germany and Halford Mackinder of Britain also supported imperialism. Ratzel believed expansion was necessary for a state’s survival while Mackinder supported Britain’s imperial expansion; these two arguments dominated the discipline for decades.

2013 Economics Nobel prize winner Robert J. Shiller said that rising inequality in the United States and elsewhere is the most important problem. Increasing inequality harms economic growth. High and persistent unemployment, in which inequality increases, has a negative effect on subsequent long-run economic growth. Unemployment can harm growth not only because it is a waste of resources, but also because it generates redistributive pressures and subsequent distortions, drives people to poverty, constrains liquidity limiting labor mobility, and erodes self-esteem promoting social dislocation, unrest and conflict. Policies aiming at controlling unemployment and in particular at reducing its inequality-associated effects support economic growth.
Persistent unemployment has what effect on short-term economic growth? (If the question is unanswerable, say "unanswerable")


The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.

To make new legislation, TFEU article 294 defines the "ordinary legislative procedure" that applies for most EU acts. The essence is there are three readings, starting with a Commission proposal, where the Parliament must vote by a majority of all MEPs (not just those present) to block or suggest changes, and the Council must vote by qualified majority to approve changes, but by unanimity to block Commission amendment. Where the different institutions cannot agree at any stage, a "Conciliation Committee" is convened, representing MEPs, ministers and the Commission to try and get agreement on a joint text: if this works, it will be sent back to the Parliament and Council to approve by absolute and qualified majority. This means, legislation can be blocked by a majority in Parliament, a minority in the Council, and a majority in the Commission: it is harder to change EU law than stay the same. A different procedure exists for budgets. For "enhanced cooperation" among a sub-set of at least member states, authorisation must be given by the Council. Member state governments should be informed by the Commission at the outset before any proposals start the legislative procedure. The EU as a whole can only act within its power set out in the Treaties. TEU articles 4 and 5 state that powers remain with the member states unless they have been conferred, although there is a debate about the Kompetenz-Kompetenz question: who ultimately has the "competence" to define the EU's "competence". Many member state courts believe they decide, other member state Parliaments believe they decide, while within the EU, the Court of Justice believes it has the final say.

Answer this question, if possible (if impossible, reply "unanswerable"): What articles state that unless conferred, powers remain with member states?


For certain physical scenarios, it is impossible to model forces as being due to gradient of potentials. This is often due to macrophysical considerations that yield forces as arising from a macroscopic statistical average of microstates. For example, friction is caused by the gradients of numerous electrostatic potentials between the atoms, but manifests as a force model that is independent of any macroscale position vector. Nonconservative forces other than friction include other contact forces, tension, compression, and drag. However, for any sufficiently detailed description, all these forces are the results of conservative ones since each of these macroscopic forces are the net results of the gradients of microscopic potentials.

Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms compounds (notably oxides) with most elements. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
2. Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. However, monitoring of atmospheric oxygen levels show a global downward trend, because of fossil-fuel burning. Oxygen is the most abundant element by mass in the Earth's crust as part of oxide compounds such as silicon dioxide, making up almost half of the crust's mass.

Uptake of O
2 from the air is the essential purpose of respiration, so oxygen supplementation is used in medicine. Treatment not only increases oxygen levels in the patient's blood, but has the secondary effect of decreasing resistance to blood flow in many types of diseased lungs, easing work load on the heart. Oxygen therapy is used to treat emphysema, pneumonia, some heart disorders (congestive heart failure), some disorders that cause increased pulmonary artery pressure, and any disease that impairs the body's ability to take up and use gaseous oxygen.

In what process is the uptake from oxygen necessary?


Read this: In 2004, declassified documents revealed that the U.S. was so distraught by the rise in oil prices and being challenged by under-developed countries that they briefly considered military action to forcibly seize Middle Eastern oilfields in late 1973. Although no explicit plan was mentioned, a conversation between U.S. Secretary of Defense James Schlesinger and British Ambassador to the United States Lord Cromer revealed Schlesinger had told him that "it was no longer obvious to him that the U.S. could not use force." British Prime Minister Edward Heath was so worried by this prospect that he ordered a British intelligence estimate of U.S. intentions, which concluded America "might consider it could not tolerate a situation in which the U.S. and its allies were at the mercy of a small group of unreasonable countries," and that they would prefer a rapid operation to seize oilfields in Saudi Arabia and Kuwait, and possibly Abu Dhabi in military action was decided upon. Although the Soviet response to such an act would likely not involve force, intelligence warned "the American occupation would need to last 10 years as the West developed alternative energy sources, and would result in the ‘total alienation’ of the Arabs and much of the rest of the Third World."

In the north eastern part of Fresno, Woodward Park was founded by the late Ralph Woodward, a long-time Fresno resident. He bequeathed a major portion of his estate in 1968 to provide a regional park and bird sanctuary in Northeast Fresno. The park lies on the South bank of the San Joaquin River between Highway 41 and Friant Road. The initial 235 acres (0.95 km2), combined with additional acres acquired later by the City, brings the park to a sizable 300 acres (1.2 km2). Now packed with amenities, Woodward Park is the only Regional Park of its size in the Central Valley. The Southeast corner of the park harbors numerous bird species offering bird enthusiasts an excellent opportunity for viewing. The park has a multi-use amphitheatre that seats up to 2,500 people, authentic Japanese Garden, fenced dog park, two-mile (3 km) equestrian trail, exercise par course, three children's playgrounds, a lake, 3 small ponds, 7 picnic areas and five miles (8 km) of multipurpose trails that are part of the San Joaquin River Parkway's Lewis S. Eaton Trail. When complete, the Lewis S. Eaton trail system will cover 22 miles (35 km) between Highway 99 and Friant Dam. The park's numerous picnic tables make for a great picnic destination and a convenient escape from city life. The park's amphetheatre was renovated in 2010, and has hosted performances by acts such as Deftones, Tech N9ne, and Sevendust as well as numerous others. The park is open April through October, 6am to 10pm and November through March, 6am to 7pm. Woodward Park is home to the annual CIF(California Interscholastic Federation) State Championship cross country meet, which takes place in late November. It is also the home of the Woodward Shakespeare Festival which began performances in the park in 2005.

In Ireland, private schools (Irish: scoil phríobháideach) are unusual because a certain number of teacher's salaries are paid by the State. If the school wishes to employ extra teachers they are paid for with school fees, which tend to be relatively low in Ireland compared to the rest of the world. There is, however, a limited element of state assessment of private schools, because of the requirement that the state ensure that children receive a certain minimum education; Irish private schools must still work towards the Junior Certificate and the Leaving Certificate, for example. Many private schools in Ireland also double as boarding schools. The average fee is around €5,000 annually for most schools, but some of these schools also provide boarding and the fees may then rise up to €25,000 per year. The fee-paying schools are usually run by a religious order, i.e., the Society of Jesus or Congregation of Christian Brothers, etc.

What is the typical annual cost for an Irish private school?

Economist Joseph Stiglitz presented evidence in 2009 that both global inequality and inequality within countries prevent growth by limiting aggregate demand. Economist Branko Milanovic, wrote in 2001 that, "The view that income inequality harms growth – or that improved equality can help sustain growth – has become more widely held in recent years. ... The main reason for this shift is the increasing importance of human capital in development. When physical capital mattered most, savings and investments were key. Then it was important to have a large contingent of rich people who could save a greater proportion of their income than the poor and invest it in physical capital. But now that human capital is scarcer than machines, widespread education has become the secret to growth."

How does inequality prevent growth?


Research by Harvard economist Robert Barro, found that there is "little overall relation between income inequality and rates of growth and investment". According to work by Barro in 1999 and 2000, high levels of inequality reduce growth in relatively poor countries but encourage growth in richer countries. A study of Swedish counties between 1960 and 2000 found a positive impact of inequality on growth with lead times of five years or less, but no correlation after ten years. Studies of larger data sets have found no correlations for any fixed lead time, and a negative impact on the duration of growth.

For a long time, it was thought that the Amazon rainforest was only ever sparsely populated, as it was impossible to sustain a large population through agriculture given the poor soil. Archeologist Betty Meggers was a prominent proponent of this idea, as described in her book Amazonia: Man and Culture in a Counterfeit Paradise. She claimed that a population density of 0.2 inhabitants per square kilometre (0.52/sq mi) is the maximum that can be sustained in the rainforest through hunting, with agriculture needed to host a larger population. However, recent anthropological findings have suggested that the region was actually densely populated. Some 5 million people may have lived in the Amazon region in AD 1500, divided between dense coastal settlements, such as that at Marajó, and inland dwellers. By 1900 the population had fallen to 1 million and by the early 1980s it was less than 200,000.

What was the theorized maximum population density per square kilometre for the Amazon rainforest?


Read this: Jacksonville is in the First Coast region of northeast Florida and is centered on the banks of the St. Johns River, about 25 miles (40 km) south of the Georgia state line and about 340 miles (550 km) north of Miami. The Jacksonville Beaches communities are along the adjacent Atlantic coast. The area was originally inhabited by the Timucua people, and in 1564 was the site of the French colony of Fort Caroline, one of the earliest European settlements in what is now the continental United States. Under British rule, settlement grew at the narrow point in the river where cattle crossed, known as Wacca Pilatka to the Seminole and the Cow Ford to the British. A platted town was established there in 1822, a year after the United States gained Florida from Spain; it was named after Andrew Jackson, the first military governor of the Florida Territory and seventh President of the United States.

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

The Rhine emerges from Lake Constance, flows generally westward, as the Hochrhein, passes the Rhine Falls, and is joined by its major tributary, the river Aare. The Aare more than doubles the Rhine's water discharge, to an average of nearly 1,000 m3/s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn, the highest point of the Rhine basin. The Rhine roughly forms the German-Swiss border from Lake Constance with the exceptions of the canton of Schaffhausen and parts of the cantons of Zürich and Basel-Stadt, until it turns north at the so-called Rhine knee at Basel, leaving Switzerland.

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

The Very high-speed Backbone Network Service (vBNS) came on line in April 1995 as part of a National Science Foundation (NSF) sponsored project to provide high-speed interconnection between NSF-sponsored supercomputing centers and select access points in the United States. The network was engineered and operated by MCI Telecommunications under a cooperative agreement with the NSF. By 1998, the vBNS had grown to connect more than 100 universities and research and engineering institutions via 12 national points of presence with DS-3 (45 Mbit/s), OC-3c (155 Mbit/s), and OC-12c (622 Mbit/s) links on an all OC-12c backbone, a substantial engineering feat for that time. The vBNS installed one of the first ever production OC-48c (2.5 Gbit/s) IP links in February 1999 and went on to upgrade the entire backbone to OC-48c.

Economist Simon Kuznets argued that levels of economic inequality are in large part the result of stages of development. According to Kuznets, countries with low levels of development have relatively equal distributions of wealth. As a country develops, it acquires more capital, which leads to the owners of this capital having more wealth and income and introducing inequality. Eventually, through various possible redistribution mechanisms such as social welfare programs, more developed countries move back to lower levels of inequality.
Try to answer this question if possible (otherwise reply "unanswerable"): What do redistribution mechanisms lead to?

Read this: Established originally by the Massachusetts legislature and soon thereafter named for John Harvard (its first benefactor), Harvard is the United States' oldest institution of higher learning, and the Harvard Corporation (formally, the President and Fellows of Harvard College) is its first chartered corporation. Although never formally affiliated with any denomination, the early College primarily trained Congregationalist and Unitarian clergy. Its curriculum and student body were gradually secularized during the 18th century, and by the 19th century Harvard had emerged as the central cultural establishment among Boston elites. Following the American Civil War, President Charles W. Eliot's long tenure (1869–1909) transformed the college and affiliated professional schools into a modern research university; Harvard was a founding member of the Association of American Universities in 1900. James Bryant Conant led the university through the Great Depression and World War II and began to reform the curriculum and liberalize admissions after the war.

Economic inequality:

Neoclassical economics views inequalities in the distribution of income as arising from differences in value added by labor, capital and land. Within labor income distribution is due to differences in value added by different classifications of workers. In this perspective, wages and profits are determined by the marginal value added of each economic actor (worker, capitalist/business owner, landlord). Thus, in a market economy, inequality is a reflection of the productivity gap between highly-paid professions and lower-paid professions.

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.

Read this: 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.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): During what type of climate is oxygen 18 in seawater at higher levels?

By July 1944, the Red Army was deep into Polish territory and pursuing the Germans toward Warsaw. Knowing that Stalin was hostile to the idea of an independent Poland, the Polish government-in-exile in London gave orders to the underground Home Army (AK) to try to seize control of Warsaw from the Germans before the Red Army arrived. Thus, on 1 August 1944, as the Red Army was nearing the city, the Warsaw Uprising began. The armed struggle, planned to last 48 hours, was partially successful, however it went on for 63 days. Eventually the Home Army fighters and civilians assisting them were forced to capitulate. They were transported to PoW camps in Germany, while the entire civilian population was expelled. Polish civilian deaths are estimated at between 150,000 and 200,000.

Beyond these rivers she held only the fertile plain of Frankfurt, opposite the Roman border fortress of Moguntiacum (Mainz), the southernmost slopes of the Black Forest and a few scattered bridge-heads. The northern section of this frontier, where the Rhine is deep and broad, remained the Roman boundary until the empire fell. The southern part was different. The upper Rhine and upper Danube are easily crossed. The frontier which they form is inconveniently long, enclosing an acute-angled wedge of foreign territory between the modern Baden and Württemberg. The Germanic populations of these lands seem in Roman times to have been scanty, and Roman subjects from the modern Alsace-Lorraine had drifted across the river eastwards.

What populations occupied the foreign territory between the modern Baden and Württemberg?


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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where are a bulk of factories concentrated along the Rhine?


Read this: As of April 2014, there are 88 private schools in New Zealand, catering for around 28,000 students or 3.7% of the entire student population. Private school numbers have been in decline since the mid-1970s as a result of many private schools opting to become state-integrated schools, mostly due of financial difficulties stemming from changes in student numbers and/or the economy. State-integrated schools keep their private school special character and receives state funds in return for having to operate like a state school, e.g. they must teach the state curriculum, they must employ registered teachers, and they can't charge tuition fees (they can charge "attendance dues" for the upkeep on the still-private school land and buildings). The largest decline in private school numbers occurred between 1979 and 1984, when the nation's then-private Catholic school system integrated. As a result, private schools in New Zealand are now largely restricted to the largest cities (Auckland, Hamilton, Wellington and Christchurch) and niche markets.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What has happened to private school numbers since 2014?


Commissioners have various privileges, such as being exempt from member state taxes (but not EU taxes), and having immunity from prosecution for doing official acts. Commissioners have sometimes been found to have abused their offices, particularly since the Santer Commission was censured by Parliament in 1999, and it eventually resigned due to corruption allegations. This resulted in one main case, Commission v Edith Cresson where the European Court of Justice held that a Commissioner giving her dentist a job, for which he was clearly unqualified, did in fact not break any law. By contrast to the ECJ's relaxed approach, a Committee of Independent Experts found that a culture had developed where few Commissioners had ‘even the slightest sense of responsibility’. This led to the creation of the European Anti-fraud Office. In 2012 it investigated the Maltese Commissioner for Health, John Dalli, who quickly resigned after allegations that he received a €60m bribe in connection with a Tobacco Products Directive. Beyond the Commission, the European Central Bank has relative executive autonomy in its conduct of monetary policy for the purpose of managing the euro. It has a six-person board appointed by the European Council, on the Council's recommendation. The President of the Council and a Commissioner can sit in on ECB meetings, but do not have voting rights.

Fresno, California:

Passenger rail service is provided by Amtrak San Joaquins. The main passenger rail station is the recently renovated historic Santa Fe Railroad Depot in Downtown Fresno. The Bakersfield-Stockton mainlines of the Burlington Northern Santa Fe Railway and Union Pacific Railroad railroads cross in Fresno, and both railroads maintain railyards within the city; the San Joaquin Valley Railroad also operates former Southern Pacific branchlines heading west and south out of the city. The city of Fresno is planned to serve the future California High Speed Rail.

Read this: The plague disease, caused by Yersinia pestis, is enzootic (commonly present) in populations of fleas carried by ground rodents, including marmots, in various areas including Central Asia, Kurdistan, Western Asia, Northern India and Uganda. Nestorian graves dating to 1338–39 near Lake Issyk Kul in Kyrgyzstan have inscriptions referring to plague and are thought by many epidemiologists to mark the outbreak of the epidemic, from which it could easily have spread to China and India. In October 2010, medical geneticists suggested that all three of the great waves of the plague originated in China. In China, the 13th century Mongol conquest caused a decline in farming and trading. However, economic recovery had been observed at the beginning of the 14th century. In the 1330s a large number of natural disasters and plagues led to widespread famine, starting in 1331, with a deadly plague arriving soon after. Epidemics that may have included plague killed an estimated 25 million Chinese and other Asians during the 15 years before it reached Constantinople in 1347.

For a phylum with relatively few species, ctenophores have a wide range of body plans. Coastal species need to be tough enough to withstand waves and swirling sediment particles, while some oceanic species are so fragile that it is very difficult to capture them intact for study. In addition oceanic species do not preserve well, and are known mainly from photographs and from observers' notes. Hence most attention has until recently concentrated on three coastal genera – Pleurobrachia, Beroe and Mnemiopsis. At least two textbooks base their descriptions of ctenophores on the cydippid Pleurobrachia.
Why are coastal species tough? (If the question is unanswerable, say "unanswerable")


Read this: The Lower Rhine flows through North Rhine-Westphalia. Its banks are usually heavily populated and industrialized, in particular the agglomerations Cologne, Düsseldorf and Ruhr area. Here the Rhine flows through the largest conurbation in Germany, the Rhine-Ruhr region. One of the most important cities in this region is Duisburg with the largest river port in Europe (Duisport). The region downstream of Duisburg is more agricultural. In Wesel, 30 km downstream of Duisburg, is located the western end of the second east-west shipping route, the Wesel-Datteln Canal, which runs parallel to the Lippe. Between Emmerich and Cleves the Emmerich Rhine Bridge, the longest suspension bridge in Germany, crosses the 400 m wide river. Near Krefeld, the river crosses the Uerdingen line, the line which separates the areas where Low German and High German are spoken.

Force:

Newton's laws and Newtonian mechanics in general were first developed to describe how forces affect idealized point particles rather than three-dimensional objects. However, in real life, matter has extended structure and forces that act on one part of an object might affect other parts of an object. For situations where lattice holding together the atoms in an object is able to flow, contract, expand, or otherwise change shape, the theories of continuum mechanics describe the way forces affect the material. For example, in extended fluids, differences in pressure result in forces being directed along the pressure gradients as follows:

Helper T cells express T cell receptors (TCR) that recognize antigen bound to Class II MHC molecules. The MHC:antigen complex is also recognized by the helper cell's CD4 co-receptor, which recruits molecules inside the T cell (e.g., Lck) that are responsible for the T cell's activation. Helper T cells have a weaker association with the MHC:antigen complex than observed for killer T cells, meaning many receptors (around 200–300) on the helper T cell must be bound by an MHC:antigen in order to activate the helper cell, while killer T cells can be activated by engagement of a single MHC:antigen molecule. Helper T cell activation also requires longer duration of engagement with an antigen-presenting cell. The activation of a resting helper T cell causes it to release cytokines that influence the activity of many cell types. Cytokine signals produced by helper T cells enhance the microbicidal function of macrophages and the activity of killer T cells. In addition, helper T cell activation causes an upregulation of molecules expressed on the T cell's surface, such as CD40 ligand (also called CD154), which provide extra stimulatory signals typically required to activate antibody-producing B cells.

Answer this question, if possible (if impossible, reply "unanswerable"): What is a ligand on the cell surface that is upregulated after helper T cell activation?


Chemical barriers also protect against infection. The skin and respiratory tract secrete antimicrobial peptides such as the β-defensins. Enzymes such as lysozyme and phospholipase A2 in saliva, tears, and breast milk are also antibacterials. Vaginal secretions serve as a chemical barrier following menarche, when they become slightly acidic, while semen contains defensins and zinc to kill pathogens. In the stomach, gastric acid and proteases serve as powerful chemical defenses against ingested pathogens.
Semen contains what in order to kill pathogens? (If the question is unanswerable, say "unanswerable")


Möngke Khan commenced a military campaign against the Chinese Song dynasty in southern China. The Mongol force that invaded southern China was far greater than the force they sent to invade the Middle East in 1256. He died in 1259 without a successor. Kublai returned from fighting the Song in 1260 when he learned that his brother, Ariq Böke, was challenging his claim to the throne. Kublai convened a kurultai in Kaiping that elected him Great Khan. A rival kurultai in Mongolia proclaimed Ariq Böke Great Khan, beginning a civil war. Kublai depended on the cooperation of his Chinese subjects to ensure that his army received ample resources. He bolstered his popularity among his subjects by modeling his government on the bureaucracy of traditional Chinese dynasties and adopting the Chinese era name of Zhongtong. Ariq Böke was hampered by inadequate supplies and surrendered in 1264. All of the three western khanates (Golden Horde, Chagatai Khanate and Ilkhanate) became functionally autonomous, although only the Ilkhans truly recognized Kublai as Great Khan. Civil strife had permanently divided the Mongol Empire.

Baran developed the concept of distributed adaptive message block switching during his research at the RAND Corporation for the US Air Force into survivable communications networks, first presented to the Air Force in the summer of 1961 as briefing B-265, later published as RAND report P-2626 in 1962, and finally in report RM 3420 in 1964. Report P-2626 described a general architecture for a large-scale, distributed, survivable communications network. The work focuses on three key ideas: use of a decentralized network with multiple paths between any two points, dividing user messages into message blocks, later called packets, and delivery of these messages by store and forward switching.

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.

Despite their soft, gelatinous bodies, fossils thought to represent ctenophores, apparently with no tentacles but many more comb-rows than modern forms, have been found in lagerstätten as far back as the early Cambrian, about 515 million years ago. The position of the ctenophores in the evolutionary family tree of animals has long been debated, and the majority view at present, based on molecular phylogenetics, is that cnidarians and bilaterians are more closely related to each other than either is to ctenophores. A recent molecular phylogenetics analysis concluded that the common ancestor of all modern ctenophores was cydippid-like, and that all the modern groups appeared relatively recently, probably after the Cretaceous–Paleogene extinction event 66 million years ago. Evidence accumulating since the 1980s indicates that the "cydippids" are not monophyletic, in other words do not include all and only the descendants of a single common ancestor, because all the other traditional ctenophore groups are descendants of various cydippids.
What do current ctenophores have that fossils found did not have? (If the question is unanswerable, say "unanswerable")


The variant forms of the name of the Rhine in modern languages are all derived from the Gaulish name Rēnos, which was adapted in Roman-era geography (1st century BC) as Greek Ῥῆνος (Rhēnos), Latin Rhenus.[note 3] The spelling with Rh- in English Rhine as well as in German Rhein and French Rhin is due to the influence of Greek orthography, while the vocalisation -i- is due to the Proto-Germanic adoption of the Gaulish name as *Rīnaz, via Old Frankish giving Old English Rín, Old High German Rīn, Dutch Rijn (formerly also spelled Rhijn)). The diphthong in modern German Rhein (also adopted in Romansh Rein, Rain) is a Central German development of the early modern period, the Alemannic name Rī(n) retaining the older vocalism,[note 4] as does Ripuarian Rhing, while Palatine has diphthongized Rhei, Rhoi. Spanish is with French in adopting the Germanic vocalism Rin-, while Italian, Occitan and Portuguese retain the Latin Ren-.

Michael Oppenheimer, a long-time participant in the IPCC and coordinating lead author of the Fifth Assessment Report conceded in Science Magazine's State of the Planet 2008-2009 some limitations of the IPCC consensus approach and asks for concurring, smaller assessments of special problems instead of the large scale approach as in the previous IPCC assessment reports. It has become more important to provide a broader exploration of uncertainties. Others see as well mixed blessings of the drive for consensus within the IPCC process and ask to include dissenting or minority positions or to improve statements about uncertainties.

When was the fifth assessment report written?


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.

There is also a growing number of new forms of procurement that involve relationship contracting where the emphasis is on a co-operative relationship between the principal and contractor and other stakeholders within a construction project. New forms include partnering such as Public-Private Partnering (PPPs) aka private finance initiatives (PFIs) and alliances such as "pure" or "project" alliances and "impure" or "strategic" alliances. The focus on co-operation is to ameliorate the many problems that arise from the often highly competitive and adversarial practices within the construction industry.

Rhine:

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

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What does the smallest and northern main branch begins as?


DECnet is a suite of network protocols created by Digital Equipment Corporation, originally released in 1975 in order to connect two PDP-11 minicomputers. It evolved into one of the first peer-to-peer network architectures, thus transforming DEC into a networking powerhouse in the 1980s. Initially built with three layers, it later (1982) evolved into a seven-layer OSI-compliant networking protocol. The DECnet protocols were designed entirely by Digital Equipment Corporation. However, DECnet Phase II (and later) were open standards with published specifications, and several implementations were developed outside DEC, including one for Linux.

Answer this question, if possible (if impossible, reply "unanswerable"): Originally built with four layers, how many layers did DEC evolve to have?


A conservative force that acts on a closed system has an associated mechanical work that allows energy to convert only between kinetic or potential forms. This means that for a closed system, the net mechanical energy is conserved whenever a conservative force acts on the system. The force, therefore, is related directly to the difference in potential energy between two different locations in space, and can be considered to be an artifact of the potential field in the same way that the direction and amount of a flow of water can be considered to be an artifact of the contour map of the elevation of an area.

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

Warsaw's first stock exchange was established in 1817 and continued trading until World War II. It was re-established in April 1991, following the end of the post-war communist control of the country and the reintroduction of a free-market economy. Today, the Warsaw Stock Exchange (WSE) is, according to many indicators, the largest market in the region, with 374 companies listed and total capitalization of 162 584 mln EUR as of 31 August 2009. From 1991 until 2000, the stock exchange was, ironically, located in the building previously used as the headquarters of the Polish United Workers' Party (PZPR).

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

The outcome of most votes can be predicted beforehand since political parties normally instruct members which way to vote. Parties entrust some MSPs, known as whips, with the task of ensuring that party members vote according to the party line. MSPs do not tend to vote against such instructions, since those who do are unlikely to reach higher political ranks in their parties. Errant members can be deselected as official party candidates during future elections, and, in serious cases, may be expelled from their parties outright. Thus, as with many Parliaments, the independence of Members of the Scottish Parliament tends to be low, and backbench rebellions by members who are discontent with their party's policies are rare. In some circumstances, however, parties announce "free votes", which allows Members to vote as they please. This is typically done on moral issues.

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.

Immigrants arrived from all over the world to search for gold, especially from Ireland and China. Many Chinese miners worked in Victoria, and their legacy is particularly strong in Bendigo and its environs. Although there was some racism directed at them, there was not the level of anti-Chinese violence that was seen at the Lambing Flat riots in New South Wales. However, there was a riot at Buckland Valley near Bright in 1857. Conditions on the gold fields were cramped and unsanitary; an outbreak of typhoid at Buckland Valley in 1854 killed over 1,000 miners.

Where were the pro-Chinese riots?


However, already in quantum mechanics there is one "caveat", namely the particles acting onto each other do not only possess the spatial variable, but also a discrete intrinsic angular momentum-like variable called the "spin", and there is the Pauli principle relating the space and the spin variables. Depending on the value of the spin, identical particles split into two different classes, fermions and bosons. If two identical fermions (e.g. electrons) have a symmetric spin function (e.g. parallel spins) the spatial variables must be antisymmetric (i.e. they exclude each other from their places much as if there was a repulsive force), and vice versa, i.e. for antiparallel spins the position variables must be symmetric (i.e. the apparent force must be attractive). Thus in the case of two fermions there is a strictly negative correlation between spatial and spin variables, whereas for two bosons (e.g. quanta of electromagnetic waves, photons) the correlation is strictly positive.

Computational complexity theory:

The integer factorization problem is the computational problem of determining the prime factorization of a given integer. Phrased as a decision problem, it is the problem of deciding whether the input has a factor less than k. No efficient integer factorization algorithm is known, and this fact forms the basis of several modern cryptographic systems, such as the RSA algorithm. The integer factorization problem is in NP and in co-NP (and even in UP and co-UP). If the problem is NP-complete, the polynomial time hierarchy will collapse to its first level (i.e., NP will equal co-NP). The best known algorithm for integer factorization is the general number field sieve, which takes time O(e(64/9)1/3(n.log 2)1/3(log (n.log 2))2/3) to factor an n-bit integer. However, the best known quantum algorithm for this problem, Shor's algorithm, does run in polynomial time. Unfortunately, this fact doesn't say much about where the problem lies with respect to non-quantum complexity classes.

The term "imperialism" is often conflated with "colonialism", however many scholars have argued that each have their own distinct definition. Imperialism and colonialism have been used in order to describe one's superiority, domination and influence upon a person or group of people. Robert Young writes that while imperialism operates from the center, is a state policy and is developed for ideological as well as financial reasons, colonialism is simply the development for settlement or commercial intentions. Colonialism in modern usage also tends to imply a degree of geographic separation between the colony and the imperial power. Particularly, Edward Said distinguishes the difference between imperialism and colonialism by stating; "imperialism involved 'the practice, the theory and the attitudes of a dominating metropolitan center ruling a distant territory', while colonialism refers to the 'implanting of settlements on a distant territory.' Contiguous land empires such as the Russian or Ottoman are generally excluded from discussions of colonialism.:116 Thus it can be said that imperialism includes some form of colonialism, but colonialism itself does not automatically imply imperialism, as it lacks a political focus.[further explanation needed]

Free movement of goods within the European Union is achieved by a customs union, and the principle of non-discrimination. The EU manages imports from non-member states, duties between member states are prohibited, and imports circulate freely. In addition under the Treaty on the Functioning of the European Union article 34, ‘Quantitative restrictions on imports and all measures having equivalent effect shall be prohibited between Member States’. In Procureur du Roi v Dassonville the Court of Justice held that this rule meant all "trading rules" that are "enacted by Member States" which could hinder trade "directly or indirectly, actually or potentially" would be caught by article 34. This meant that a Belgian law requiring Scotch whisky imports to have a certificate of origin was unlikely to be lawful. It discriminated against parallel importers like Mr Dassonville, who could not get certificates from authorities in France, where they bought the Scotch. This "wide test", to determine what could potentially be an unlawful restriction on trade, applies equally to actions by quasi-government bodies, such as the former "Buy Irish" company that had government appointees. It also means states can be responsible for private actors. For instance, in Commission v France French farmer vigilantes were continually sabotaging shipments of Spanish strawberries, and even Belgian tomato imports. France was liable for these hindrances to trade because the authorities ‘manifestly and persistently abstained' from preventing the sabotage. Generally speaking, if a member state has laws or practices that directly discriminate against imports (or exports under TFEU article 35) then it must be justified under article 36. The justifications include public morality, policy or security, "protection of health and life of humans, animals or plants", "national treasures" of "artistic, historic or archaeological value" and "industrial and commercial property." In addition, although not clearly listed, environmental protection can justify restrictions on trade as an overriding requirement derived from TFEU article 11. More generally, it has been increasingly acknowledged that fundamental human rights should take priority over all trade rules. So, in Schmidberger v Austria the Court of Justice held that Austria did not infringe article 34 by failing to ban a protest that blocked heavy traffic passing over the A13, Brenner Autobahn, en route to Italy. Although many companies, including Mr Schmidberger's German undertaking, were prevented from trading, the Court of Justice reasoned that freedom of association is one of the ‘fundamental pillars of a democratic society’, against which the free movement of goods had to be balanced, and was probably subordinate. If a member state does appeal to the article 36 justification, the measures it takes have to be applied proportionately. This means the rule must be pursue a legitimate aim and (1) be suitable to achieve the aim, (2) be necessary, so that a less restrictive measure could not achieve the same result, and (3) be reasonable in balancing the interests of free trade with interests in article 36.

Read this: Building construction is the process of adding structure to real property or construction of buildings. The majority of building construction jobs are small renovations, such as addition of a room, or renovation of a bathroom. Often, the owner of the property acts as laborer, paymaster, and design team for the entire project. Although building construction projects typically include various common elements, such as design, financial, estimating and legal considerations, many projects of varying sizes reach undesirable end results, such as structural collapse, cost overruns, and/or litigation. For this reason, those with experience in the field make detailed plans and maintain careful oversight during the project to ensure a positive outcome.

The efficiency of a Rankine cycle is usually limited by the working fluid. Without the pressure reaching supercritical levels for the working fluid, the temperature range the cycle can operate over is quite small; in steam turbines, turbine entry temperatures are typically 565 °C (the creep limit of stainless steel) and condenser temperatures are around 30 °C. This gives a theoretical Carnot efficiency of about 63% compared with an actual efficiency of 42% for a modern coal-fired power station. This low turbine entry temperature (compared with a gas turbine) is why the Rankine cycle is often used as a bottoming cycle in combined-cycle gas turbine power stations.[citation needed]

What is 63 degrees celsius the creep limit of?


Geology:

All of these processes do not necessarily occur in a single environment, and do not necessarily occur in a single order. The Hawaiian Islands, for example, consist almost entirely of layered basaltic lava flows. The sedimentary sequences of the mid-continental United States and the Grand Canyon in the southwestern United States contain almost-undeformed stacks of sedimentary rocks that have remained in place since Cambrian time. Other areas are much more geologically complex. In the southwestern United States, sedimentary, volcanic, and intrusive rocks have been metamorphosed, faulted, foliated, and folded. Even older rocks, such as the Acasta gneiss of the Slave craton in northwestern Canada, the oldest known rock in the world have been metamorphosed to the point where their origin is undiscernable without laboratory analysis. In addition, these processes can occur in stages. In many places, the Grand Canyon in the southwestern United States being a very visible example, the lower rock units were metamorphosed and deformed, and then deformation ended and the upper, undeformed units were deposited. Although any amount of rock emplacement and rock deformation can occur, and they can occur any number of times, these concepts provide a guide to understanding the geological history of an area.

The project must adhere to zoning and building code requirements. Constructing a project that fails to adhere to codes does not benefit the owner. Some legal requirements come from malum in se considerations, or the desire to prevent things that are indisputably bad – bridge collapses or explosions. Other legal requirements come from malum prohibitum considerations, or things that are a matter of custom or expectation, such as isolating businesses to a business district and residences to a residential district. An attorney may seek changes or exemptions in the law that governs the land where the building will be built, either by arguing that a rule is inapplicable (the bridge design will not cause a collapse), or that the custom is no longer needed (acceptance of live-work spaces has grown in the community).

Read this: A B cell identifies pathogens when antibodies on its surface bind to a specific foreign antigen. This antigen/antibody complex is taken up by the B cell and processed by proteolysis into peptides. The B cell then displays these antigenic peptides on its surface MHC class II molecules. This combination of MHC and antigen attracts a matching helper T cell, which releases lymphokines and activates the B cell. As the activated B cell then begins to divide, its offspring (plasma cells) secrete millions of copies of the antibody that recognizes this antigen. These antibodies circulate in blood plasma and lymph, bind to pathogens expressing the antigen and mark them for destruction by complement activation or for uptake and destruction by phagocytes. Antibodies can also neutralize challenges directly, by binding to bacterial toxins or by interfering with the receptors that viruses and bacteria use to infect cells.

In the early years the College trained many Puritan ministers.[citation needed] (A 1643 publication said the school's purpose was "to advance learning and perpetuate it to posterity, dreading to leave an illiterate ministry to the churches when our present ministers shall lie in the dust".) It offered a classic curriculum on the English university model—many leaders in the colony had attended the University of Cambridge—but conformed Puritanism. It was never affiliated with any particular denomination, but many of its earliest graduates went on to become clergymen in Congregational and Unitarian churches.

Many machine models different from the standard multi-tape Turing machines have been proposed in the literature, for example random access machines. Perhaps surprisingly, each of these models can be converted to another without providing any extra computational power. The time and memory consumption of these alternate models may vary. What all these models have in common is that the machines operate deterministically.

What commonality do alternate machine models, such as random access machines, share with Turing machines?


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

The Rankine cycle is sometimes referred to as a practical Carnot cycle because, when an efficient turbine is used, the TS diagram begins to resemble the Carnot cycle. The main difference is that heat addition (in the boiler) and rejection (in the condenser) are isobaric (constant pressure) processes in the Rankine cycle and isothermal (constant temperature) processes in the theoretical Carnot cycle. In this cycle a pump is used to pressurize the working fluid which is received from the condenser as a liquid not as a gas. Pumping the working fluid in liquid form during the cycle requires a small fraction of the energy to transport it compared to the energy needed to compress the working fluid in gaseous form in a compressor (as in the Carnot cycle). The cycle of a reciprocating steam engine differs from that of turbines because of condensation and re-evaporation occurring in the cylinder or in the steam inlet passages.

Read this: 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.

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.

The Upper Rhine region was changed significantly by a Rhine straightening program in the 19th Century. The rate of flow was increased and the ground water level fell significantly. Dead branches dried up and the amount of forests on the flood plains decreased sharply. On the French side, the Grand Canal d'Alsace was dug, which carries a significant part of the river water, and all of the traffic. In some places, there are large compensation pools, for example the huge Bassin de compensation de Plobsheim in Alsace.

In the United Kingdom and several other Commonwealth countries including Australia and Canada, the use of the term is generally restricted to primary and secondary educational levels; it is almost never used of universities and other tertiary institutions. Private education in North America covers the whole gamut of educational activity, ranging from pre-school to tertiary level institutions. Annual tuition fees at K-12 schools range from nothing at so called 'tuition-free' schools to more than $45,000 at several New England preparatory schools.

Victorian schools are either publicly or privately funded. Public schools, also known as state or government schools, are funded and run directly by the Victoria Department of Education . Students do not pay tuition fees, but some extra costs are levied. Private fee-paying schools include parish schools run by the Roman Catholic Church and independent schools similar to British public schools. Independent schools are usually affiliated with Protestant churches. Victoria also has several private Jewish and Islamic primary and secondary schools. Private schools also receive some public funding. All schools must comply with government-set curriculum standards. In addition, Victoria has four government selective schools, Melbourne High School for boys, MacRobertson Girls' High School for girls, the coeducational schools John Monash Science School, Nossal High School and Suzanne Cory High School, and The Victorian College of the Arts Secondary School. Students at these schools are exclusively admitted on the basis of an academic selective entry test.

In contrast to product requirements or other laws that hinder market access, the Court of Justice developed a presumption that "selling arrangements" would be presumed to not fall into TFEU article 34, if they applied equally to all sellers, and affected them in the same manner in fact. In Keck and Mithouard two importers claimed that their prosecution under a French competition law, which prevented them selling Picon beer under wholesale price, was unlawful. The aim of the law was to prevent cut throat competition, not to hinder trade. The Court of Justice held, as "in law and in fact" it was an equally applicable "selling arrangement" (not something that alters a product's content) it was outside the scope of article 34, and so did not need to be justified. Selling arrangements can be held to have an unequal effect "in fact" particularly where traders from another member state are seeking to break into the market, but there are restrictions on advertising and marketing. In Konsumentombudsmannen v De Agostini the Court of Justice reviewed Swedish bans on advertising to children under age 12, and misleading commercials for skin care products. While the bans have remained (justifiable under article 36 or as a mandatory requirement) the Court emphasised that complete marketing bans could be disproportionate if advertising were "the only effective form of promotion enabling [a trader] to penetrate" the market. In Konsumentombudsmannen v Gourmet AB the Court suggested that a total ban for advertising alcohol on the radio, TV and in magazines could fall within article 34 where advertising was the only way for sellers to overcome consumers' "traditional social practices and to local habits and customs" to buy their products, but again the national courts would decide whether it was justified under article 36 to protect public health. Under the Unfair Commercial Practices Directive, the EU harmonised restrictions on restrictions on marketing and advertising, to forbid conduct that distorts average consumer behaviour, is misleading or aggressive, and sets out a list of examples that count as unfair. Increasingly, states have to give mutual recognition to each other's standards of regulation, while the EU has attempted to harmonise minimum ideals of best practice. The attempt to raise standards is hoped to avoid a regulatory "race to the bottom", while allowing consumers access to goods from around the continent.

Which two importers did not claim that under French competition law, they were prevented from selling Picon beer under wholesale price?


Read this: The first buildings of the University of Chicago campus, which make up what is now known as the Main Quadrangles, were part of a "master plan" conceived by two University of Chicago trustees and plotted by Chicago architect Henry Ives Cobb. The Main Quadrangles consist of six quadrangles, each surrounded by buildings, bordering one larger quadrangle. The buildings of the Main Quadrangles were designed by Cobb, Shepley, Rutan and Coolidge, Holabird & Roche, and other architectural firms in a mixture of the Victorian Gothic and Collegiate Gothic styles, patterned on the colleges of the University of Oxford. (Mitchell Tower, for example, is modeled after Oxford's Magdalen Tower, and the university Commons, Hutchinson Hall, replicates Christ Church Hall.)

Harvard was formed in 1636 by vote of the Great and General Court of the Massachusetts Bay Colony. It was initially called "New College" or "the college at New Towne". In 1638, the college became home for North America's first known printing press, carried by the ship John of London. In 1639, the college was renamed Harvard College after deceased clergyman John Harvard, who was an alumnus of the University of Cambridge. He had left the school £779 and his library of some 400 books. The charter creating the Harvard Corporation was granted in 1650.

The evolutionary strategy used by cicadas of the genus Magicicada make use of prime numbers. These insects spend most of their lives as grubs underground. They only pupate and then emerge from their burrows after 7, 13 or 17 years, at which point they fly about, breed, and then die after a few weeks at most. The logic for this is believed to be that the prime number intervals between emergences make it very difficult for predators to evolve that could specialize as predators on Magicicadas. If Magicicadas appeared at a non-prime number intervals, say every 12 years, then predators appearing every 2, 3, 4, 6, or 12 years would be sure to meet them. Over a 200-year period, average predator populations during hypothetical outbreaks of 14- and 15-year cicadas would be up to 2% higher than during outbreaks of 13- and 17-year cicadas. Though small, this advantage appears to have been enough to drive natural selection in favour of a prime-numbered life-cycle for these insects.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of insect employs the use of Magicicadas in its evolutionary strategy?


Following the Cretaceous–Paleogene extinction event, the extinction of the dinosaurs and the wetter climate may have allowed the tropical rainforest to spread out across the continent. From 66–34 Mya, the rainforest extended as far south as 45°. Climate fluctuations during the last 34 million years have allowed savanna regions to expand into the tropics. During the Oligocene, for example, the rainforest spanned a relatively narrow band. It expanded again during the Middle Miocene, then retracted to a mostly inland formation at the last glacial maximum. However, the rainforest still managed to thrive during these glacial periods, allowing for the survival and evolution of a broad diversity of species.

The Rhine emerges from Lake Constance, flows generally westward, as the Hochrhein, passes the Rhine Falls, and is joined by its major tributary, the river Aare. The Aare more than doubles the Rhine's water discharge, to an average of nearly 1,000 m3/s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn, the highest point of the Rhine basin. The Rhine roughly forms the German-Swiss border from Lake Constance with the exceptions of the canton of Schaffhausen and parts of the cantons of Zürich and Basel-Stadt, until it turns north at the so-called Rhine knee at Basel, leaving Switzerland.

Where is the highest point of the Rhine basin?


A particularly simple example of a probabilistic test is the Fermat primality test, which relies on the fact (Fermat's little theorem) that np≡n (mod p) for any n if p is a prime number. If we have a number b that we want to test for primality, then we work out nb (mod b) for a random value of n as our test. A flaw with this test is that there are some composite numbers (the Carmichael numbers) that satisfy the Fermat identity even though they are not prime, so the test has no way of distinguishing between prime numbers and Carmichael numbers. Carmichael numbers are substantially rarer than prime numbers, though, so this test can be useful for practical purposes. More powerful extensions of the Fermat primality test, such as the Baillie-PSW, Miller-Rabin, and Solovay-Strassen tests, are guaranteed to fail at least some of the time when applied to a composite number.
Try to answer this question if possible (otherwise reply "unanswerable"): What is the name of another compelling continuation of the Fermat primality test?

Another of the Egyptian groups which employed violence in their struggle for Islamic order was al-Gama'a al-Islamiyya (Islamic Group). Victims of their campaign against the Egyptian state in the 1990s included the head of the counter-terrorism police (Major General Raouf Khayrat), a parliamentary speaker (Rifaat al-Mahgoub), dozens of European tourists and Egyptian bystanders, and over 100 Egyptian police. Ultimately the campaign to overthrow the government was unsuccessful, and the major jihadi group, Jamaa Islamiya (or al-Gama'a al-Islamiyya), renounced violence in 2003. Other lesser known groups include the Islamic Liberation Party, Salvation from Hell and Takfir wal-Hijra, and these groups have variously been involved in activities such as attempted assassinations of political figures, arson of video shops and attempted takeovers of government buildings.

How did the Islamic Group's campaign to support the government turn out?


Rhine:

The last glacial ran from ~74,000 (BP = Before Present), until the end of the Pleistocene (~11,600 BP). In northwest Europe, it saw two very cold phases, peaking around 70,000 BP and around 29,000–24,000 BP. The last phase slightly predates the global last ice age maximum (Last Glacial Maximum). During this time, the lower Rhine flowed roughly west through the Netherlands and extended to the southwest, through the English Channel and finally, to the Atlantic Ocean. The English Channel, the Irish Channel and most of the North Sea were dry land, mainly because sea level was approximately 120 m (390 ft) lower than today.
