In Europe, the North American theater of the Seven Years' War usually is not given a separate name. The entire international conflict is known as the Seven Years' War. "Seven Years" refers to events in Europe, from the official declaration of war in 1756 to the signing of the peace treaty in 1763. These dates do not correspond with the fighting on mainland North America, where the fighting between the two colonial powers was largely concluded in six years, from the Battle of Jumonville Glen in 1754 to the capture of Montreal in 1760.

What was first battle in 1754?


Read this: 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.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What were states not responsible for in Article 34?

In 1939, c. 1,300,000 people lived in Warsaw, but in 1945 – only 420,000. During the first years after the war, the population growth was c. 6%, so shortly the city started to suffer from the lack of flats and of areas for new houses. The first remedial measure was the Warsaw area enlargement (1951) – but the city authorities were still forced to introduce residency registration limitations: only the spouses and children of the permanent residents as well as some persons of public importance (like renowned specialists) were allowed to get the registration, hence halving the population growth in the following years. It also bolstered some kind of conviction among Poles that Varsovians thought of themselves as better only because they lived in the capital. Unfortunately this belief still lives on in Poland (although not as much as it used to be) – even though since 1990 there are no limitations to residency registration anymore.

What had the number of people living in Poland declined to by 1945?


In the United States, the industry in 2014 has around $960 billion in annual revenue according to statistics tracked by the Census Bureau, of which $680 billion is private (split evenly between residential and nonresidential) and the remainder is government. As of 2005, there were about 667,000 firms employing 1 million contractors (200,000 general contractors, 38,000 heavy, and 432,000 specialty); the average contractor employed fewer than 10 employees. As a whole, the industry employed an estimated 5.8 million as of April 2013, with a 13.2% unemployment rate. In the United States, approximately 828,000 women were employed in the construction industry as of 2011.

Read this: Harvard's 209-acre (85 ha) main campus is centered on Harvard Yard in Cambridge, about 3 miles (5 km) west-northwest of the State House in downtown Boston, and extends into the surrounding Harvard Square neighborhood. Harvard Yard itself contains the central administrative offices and main libraries of the university, academic buildings including Sever Hall and University Hall, Memorial Church, and the majority of the freshman dormitories. Sophomore, junior, and senior undergraduates live in twelve residential Houses, nine of which are south of Harvard Yard along or near the Charles River. The other three are located in a residential neighborhood half a mile northwest of the Yard at the Quadrangle (commonly referred to as the Quad), which formerly housed Radcliffe College students until Radcliffe merged its residential system with Harvard. Each residential house contains rooms for undergraduates, House masters, and resident tutors, as well as a dining hall and library. The facilities were made possible by a gift from Yale University alumnus Edward Harkness.

How many residential dorms house upper class, sophomore, Jr, and Sr students?

When suffering from sleep deprivation, active immunizations may have a diminished effect and may result in lower antibody production, and a lower immune response, than would be noted in a well-rested individual. Additionally, proteins such as NFIL3, which have been shown to be closely intertwined with both T-cell differentiation and our circadian rhythms, can be affected through the disturbance of natural light and dark cycles through instances of sleep deprivation, shift work, etc. As a result, these disruptions can lead to an increase in chronic conditions such as heart disease, chronic pain, and asthma.

Almost all ctenophores are predators, taking prey ranging from microscopic larvae and rotifers to the adults of small crustaceans; the exceptions are juveniles of two species, which live as parasites on the salps on which adults of their species feed. In favorable circumstances, ctenophores can eat ten times their own weight in a day. Only 100–150 species have been validated, and possibly another 25 have not been fully described and named. The textbook examples are cydippids with egg-shaped bodies and a pair of retractable tentacles fringed with tentilla ("little tentacles") that are covered with colloblasts, sticky cells that capture prey. The phylum has a wide range of body forms, including the flattened, deep-sea platyctenids, in which the adults of most species lack combs, and the coastal beroids, which lack tentacles and prey on other ctenophores by using huge mouths armed with groups of large, stiffened cilia that act as teeth. These variations enable different species to build huge populations in the same area, because they specialize in different types of prey, which they capture by as wide a range of methods as spiders use.

What do coastal beroids not have that other ctenophora have?


The popular neighborhood known as the Tower District is centered around the historic Tower Theatre, which is included on the National List of Historic Places. The theater was built in 1939 and is at Olive and Wishon Avenues in the heart of the Tower District. (The name of the theater refers to a well-known landmark water tower, which is actually in another nearby area). The Tower District neighborhood is just north of downtown Fresno proper, and one-half mile south of Fresno City College. Although the neighborhood was known as a residential area prior, the early commercial establishments of the Tower District began with small shops and services that flocked to the area shortly after World War II. The character of small local businesses largely remains today. To some extent, the businesses of the Tower District were developed due to the proximity of the original Fresno Normal School, (later renamed California State University at Fresno). In 1916 the college moved to what is now the site of Fresno City College one-half mile north of the Tower District.

It was shown by Ladner that if P ≠ NP then there exist problems in NP that are neither in P nor NP-complete. Such problems are called NP-intermediate problems. The graph isomorphism problem, the discrete logarithm problem and the integer factorization problem are examples of problems believed to be NP-intermediate. They are some of the very few NP problems not known to be in P or to be NP-complete.

What are four examples of problems believed to be NP=intermediate?


can have infinitely many primes only when a and q are coprime, i.e., their greatest common divisor is one. If this necessary condition is satisfied, Dirichlet's theorem on arithmetic progressions asserts that the progression contains infinitely many primes. The picture below illustrates this with q = 9: the numbers are "wrapped around" as soon as a multiple of 9 is passed. Primes are highlighted in red. The rows (=progressions) starting with a = 3, 6, or 9 contain at most one prime number. In all other rows (a = 1, 2, 4, 5, 7, and 8) there are infinitely many prime numbers. What is more, the primes are distributed equally among those rows in the long run—the density of all primes congruent a modulo 9 is 1/6.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): If a and q are coprime, which theorem holds that an arithmetic progression has an infinite number of wraps?


The normal force is due to repulsive forces of interaction between atoms at close contact. When their electron clouds overlap, Pauli repulsion (due to fermionic nature of electrons) follows resulting in the force that acts in a direction normal to the surface interface between two objects.:93 The normal force, for example, is responsible for the structural integrity of tables and floors as well as being the force that responds whenever an external force pushes on a solid object. An example of the normal force in action is the impact force on an object crashing into an immobile surface.

Computational complexity theory is a branch of the theory of computation in theoretical computer science that focuses on classifying computational problems according to their inherent difficulty, and relating those classes to each other. A computational problem is understood to be a task that is in principle amenable to being solved by a computer, which is equivalent to stating that the problem may be solved by mechanical application of mathematical steps, such as an algorithm.

What branch of theoretical computer science deals with broadly classifying computational problems by difficulty and class of relationship?

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

What function is related to prime numbers?


Between the 1880s and World War II, Downtown Fresno flourished, filled with electric Street Cars, and contained some of the San Joaquin Valley's most beautiful architectural buildings. Among them, the original Fresno County Courthouse (demolished), the Fresno Carnegie Public Library (demolished), the Fresno Water Tower, the Bank of Italy Building, the Pacific Southwest Building, the San Joaquin Light & Power Building (currently known as the Grand 1401), and the Hughes Hotel (burned down), to name a few.

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

Sky (United Kingdom):

BSkyB launched its HDTV service, Sky+ HD, on 22 May 2006. Prior to its launch, BSkyB claimed that 40,000 people had registered to receive the HD service. In the week before the launch, rumours started to surface that BSkyB was having supply issues with its set top box (STB) from manufacturer Thomson. On Thursday 18 May 2006, and continuing through the weekend before launch, people were reporting that BSkyB had either cancelled or rescheduled its installation. Finally, the BBC reported that 17,000 customers had yet to receive the service due to failed deliveries. On 31 March 2012, Sky announced the total number of homes with Sky+HD was 4,222,000.

This is the most common method of construction procurement and is well established and recognized. In this arrangement, the architect or engineer acts as the project coordinator. His or her role is to design the works, prepare the specifications and produce construction drawings, administer the contract, tender the works, and manage the works from inception to completion. There are direct contractual links between the architect's client and the main contractor. Any subcontractor has a direct contractual relationship with the main contractor. The procedure continues until the building is ready to occupy.

In most jurisdictions (such as the United States), pharmacists are regulated separately from physicians. These jurisdictions also usually specify that only pharmacists may supply scheduled pharmaceuticals to the public, and that pharmacists cannot form business partnerships with physicians or give them "kickback" payments. However, the American Medical Association (AMA) Code of Ethics provides that physicians may dispense drugs within their office practices as long as there is no patient exploitation and patients have the right to a written prescription that can be filled elsewhere. 7 to 10 percent of American physicians practices reportedly dispense drugs on their own.

Answer this question, if possible (if impossible, reply "unanswerable"): What is the estimate of how many physicians give out drugs on their own?


In the fall quarter of 2014, the University of Chicago enrolled 5,792 students in the College, 3,468 students in its four graduate divisions, 5,984 students in its professional schools, and 15,244 students overall. In the 2012 Spring Quarter, international students comprised almost 19% of the overall study body, over 26% of students were domestic ethnic minorities, and about 44% of enrolled students were female. Admissions to the University of Chicago is highly selective. The middle 50% band of SAT scores for the undergraduate class of 2015, excluding the writing section, was 1420–1530, the average MCAT score for entering students in the Pritzker School of Medicine in 2011 was 36, and the median LSAT score for entering students in the Law School in 2011 was 171.

Black Death:

The plague struck various countries in the Middle East during the pandemic, leading to serious depopulation and permanent change in both economic and social structures. As it spread to western Europe, the disease entered the region from southern Russia also. By autumn 1347, the plague reached Alexandria in Egypt, probably through the port's trade with Constantinople, and ports on the Black Sea. During 1347, the disease travelled eastward to Gaza, and north along the eastern coast to cities in Lebanon, Syria and Palestine, including Ashkelon, Acre, Jerusalem, Sidon, Damascus, Homs, and Aleppo. In 1348–49, the disease reached Antioch. The city's residents fled to the north, most of them dying during the journey, but the infection had been spread to the people of Asia Minor.[citation needed]

European Union law is a body of treaties and legislation, such as Regulations and Directives, which have direct effect or indirect effect on the laws of European Union member states. The three sources of European Union law are primary law, secondary law and supplementary law. The main sources of primary law are the Treaties establishing the European Union. Secondary sources include regulations and directives which are based on the Treaties. The legislature of the European Union is principally composed of the European Parliament and the Council of the European Union, which under the Treaties may establish secondary law to pursue the objective set out in the Treaties.

What effect does European Union law have on laws of member states?

The Free Movement of Workers Regulation articles 1 to 7 set out the main provisions on equal treatment of workers. First, articles 1 to 4 generally require that workers can take up employment, conclude contracts, and not suffer discrimination compared to nationals of the member state. In a famous case, the Belgian Football Association v Bosman, a Belgian footballer named Jean-Marc Bosman claimed that he should be able to transfer from R.F.C. de Liège to USL Dunkerque when his contract finished, regardless of whether Dunkerque could afford to pay Liège the habitual transfer fees. The Court of Justice held "the transfer rules constitute[d] an obstacle to free movement" and were unlawful unless they could be justified in the public interest, but this was unlikely. In Groener v Minister for Education the Court of Justice accepted that a requirement to speak Gaelic to teach in a Dublin design college could be justified as part of the public policy of promoting the Irish language, but only if the measure was not disproportionate. By contrast in Angonese v Cassa di Risparmio di Bolzano SpA a bank in Bolzano, Italy, was not allowed to require Mr Angonese to have a bilingual certificate that could only be obtained in Bolzano. The Court of Justice, giving "horizontal" direct effect to TFEU article 45, reasoned that people from other countries would have little chance of acquiring the certificate, and because it was "impossible to submit proof of the required linguistic knowledge by any other means", the measure was disproportionate. Second, article 7(2) requires equal treatment in respect of tax. In Finanzamt Köln Altstadt v Schumacker the Court of Justice held that it contravened TFEU art 45 to deny tax benefits (e.g. for married couples, and social insurance expense deductions) to a man who worked in Germany, but was resident in Belgium when other German residents got the benefits. By contrast in Weigel v Finanzlandesdirektion für Vorarlberg the Court of Justice rejected Mr Weigel's claim that a re-registration charge upon bringing his car to Austria violated his right to free movement. Although the tax was "likely to have a negative bearing on the decision of migrant workers to exercise their right to freedom of movement", because the charge applied equally to Austrians, in absence of EU legislation on the matter it had to be regarded as justified. Third, people must receive equal treatment regarding "social advantages", although the Court has approved residential qualifying periods. In Hendrix v Employee Insurance Institute the Court of Justice held that a Dutch national was not entitled to continue receiving incapacity benefits when he moved to Belgium, because the benefit was "closely linked to the socio-economic situation" of the Netherlands. Conversely, in Geven v Land Nordrhein-Westfalen the Court of Justice held that a Dutch woman living in the Netherlands, but working between 3 and 14 hours a week in Germany, did not have a right to receive German child benefits, even though the wife of a man who worked full-time in Germany but was resident in Austria could. The general justifications for limiting free movement in TFEU article 45(3) are "public policy, public security or public health", and there is also a general exception in article 45(4) for "employment in the public service".

What did articles 1 to 4 not generally require of workers?


where  is the relevant cross-sectional area for the volume for which the stress-tensor is being calculated. This formalism includes pressure terms associated with forces that act normal to the cross-sectional area (the matrix diagonals of the tensor) as well as shear terms associated with forces that act parallel to the cross-sectional area (the off-diagonal elements). The stress tensor accounts for forces that cause all strains (deformations) including also tensile stresses and compressions.:133–134:38-1–38-11

Aristotle provided a philosophical discussion of the concept of a force as an integral part of Aristotelian cosmology. In Aristotle's view, the terrestrial sphere contained four elements that come to rest at different "natural places" therein. Aristotle believed that motionless objects on Earth, those composed mostly of the elements earth and water, to be in their natural place on the ground and that they will stay that way if left alone. He distinguished between the innate tendency of objects to find their "natural place" (e.g., for heavy bodies to fall), which led to "natural motion", and unnatural or forced motion, which required continued application of a force. This theory, based on the everyday experience of how objects move, such as the constant application of a force needed to keep a cart moving, had conceptual trouble accounting for the behavior of projectiles, such as the flight of arrows. The place where the archer moves the projectile was at the start of the flight, and while the projectile sailed through the air, no discernible efficient cause acts on it. Aristotle was aware of this problem and proposed that the air displaced through the projectile's path carries the projectile to its target. This explanation demands a continuum like air for change of place in general.

A further type of committee is normally set up to scrutinise private bills submitted to the Scottish Parliament by an outside party or promoter who is not a member of the Scottish Parliament or Scottish Government. Private bills normally relate to large-scale development projects such as infrastructure projects that require the use of land or property. Private Bill Committees have been set up to consider legislation on issues such as the development of the Edinburgh Tram Network, the Glasgow Airport Rail Link, the Airdrie-Bathgate Rail Link and extensions to the National Gallery of Scotland.

Read this: Residential construction practices, technologies, and resources must conform to local building authority regulations and codes of practice. Materials readily available in the area generally dictate the construction materials used (e.g. brick versus stone, versus timber). Cost of construction on a per square meter (or per square foot) basis for houses can vary dramatically based on site conditions, local regulations, economies of scale (custom designed homes are often more expensive to build) and the availability of skilled tradespeople. As residential construction (as well as all other types of construction) can generate a lot of waste, careful planning again is needed here.

Rhine:

The flow of cold, gray mountain water continues for some distance into the lake. The cold water flows near the surface and at first doesn't mix with the warmer, green waters of Upper Lake. But then, at the so-called Rheinbrech, the Rhine water abruptly falls into the depths because of the greater density of cold water. The flow reappears on the surface at the northern (German) shore of the lake, off the island of Lindau. The water then follows the northern shore until Hagnau am Bodensee. A small fraction of the flow is diverted off the island of Mainau into Lake Überlingen. Most of the water flows via the Constance hopper into the Rheinrinne ("Rhine Gutter") and Seerhein. Depending on the water level, this flow of the Rhine water is clearly visible along the entire length of the lake.

Economic inequality:

Conservative researchers have argued that income inequality is not significant because consumption, rather than income should be the measure of inequality, and inequality of consumption is less extreme than inequality of income in the US. Will Wilkinson of the libertarian Cato Institute states that "the weight of the evidence shows that the run-up in consumption inequality has been considerably less dramatic than the rise in income inequality," and consumption is more important than income. According to Johnson, Smeeding, and Tory, consumption inequality was actually lower in 2001 than it was in 1986. The debate is summarized in "The Hidden Prosperity of the Poor" by journalist Thomas B. Edsall. Other studies have not found consumption inequality less dramatic than household income inequality, and the CBO's study found consumption data not "adequately" capturing "consumption by high-income households" as it does their income, though it did agree that household consumption numbers show more equal distribution than household income.

Several commemorative events take place every year. Gatherings of thousands of people on the banks of the Vistula on Midsummer’s Night for a festival called Wianki (Polish for Wreaths) have become a tradition and a yearly event in the programme of cultural events in Warsaw. The festival traces its roots to a peaceful pagan ritual where maidens would float their wreaths of herbs on the water to predict when they would be married, and to whom. By the 19th century this tradition had become a festive event, and it continues today. The city council organize concerts and other events. Each Midsummer’s Eve, apart from the official floating of wreaths, jumping over fires, looking for the fern flower, there are musical performances, dignitaries' speeches, fairs and fireworks by the river bank.

What is the polish word for concerts?


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.

where  is the mass of the object,  is the velocity of the object and  is the distance to the center of the circular path and  is the unit vector pointing in the radial direction outwards from the center. This means that the unbalanced centripetal force felt by any object is always directed toward the center of the curving path. Such forces act perpendicular to the velocity vector associated with the motion of an object, and therefore do not change the speed of the object (magnitude of the velocity), but only the direction of the velocity vector. The unbalanced force that accelerates an object can be resolved into a component that is perpendicular to the path, and one that is tangential to the path. This yields both the tangential force, which accelerates the object by either slowing it down or speeding it up, and the radial (centripetal) force, which changes its direction.

A balance force accelerates what?


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:

The French population numbered about 75,000 and was heavily concentrated along the St. Lawrence River valley, with some also in Acadia (present-day New Brunswick and parts of Nova Scotia, including Île Royale (present-day Cape Breton Island)). Fewer lived in New Orleans, Biloxi, Mississippi, Mobile, Alabama and small settlements in the Illinois Country, hugging the east side of the Mississippi River and its tributaries. French fur traders and trappers traveled throughout the St. Lawrence and Mississippi watersheds, did business with local tribes, and often married Indian women. Traders married daughters of chiefs, creating high-ranking unions.

Private school:

Private schools are often Anglican, such as King's College and Diocesan School for Girls in Auckland, St Paul's Collegiate School in Hamilton, St Peter's School in Cambridge, Samuel Marsden Collegiate School in Wellington, and Christ's College and St Margaret's College in Christchurch; or Presbyterian, such as Saint Kentigern College and St Cuthbert's College in Auckland, Scots College and Queen Margaret College in Wellington, and St Andrew's College and Rangi Ruru Girls' School in Christchurch. Academic Colleges Group is a recent group of private schools run as a business, with schools throughout Auckland, including ACG Senior College in Auckland’s CBD, ACG Parnell College in Parnell, and international school ACG New Zealand International College. There are three private schools (including the secondary school, St Dominic's College) operated by the Catholic schismatic group, the Society of St Pius X in Wanganui.

Jacksonville is the most populous city in Florida, and the twelfth most populous city in the United States. As of 2010[update], there were 821,784 people and 366,273 households in the city. Jacksonville has the country's tenth-largest Arab population, with a total population of 5,751 according to the 2000 United States Census. Jacksonville has Florida's largest Filipino American community, with 25,033 in the metropolitan area as of the 2010 Census. Much of Jacksonville's Filipino community served in or has ties to the United States Navy.

What military branch does much of Jacksonville's Arab population have ties to?


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

Answer this question, if possible (if impossible, reply "unanswerable"): How much had the price of gold risen after 1971?


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

In southern Europe, the stage was set in the Triassic Period of the Mesozoic Era, with the opening of the Tethys Ocean, between the Eurasian and African tectonic plates, between about 240 MBP and 220 MBP (million years before present). The present Mediterranean Sea descends from this somewhat larger Tethys sea. At about 180 MBP, in the Jurassic Period, the two plates reversed direction and began to compress the Tethys floor, causing it to be subducted under Eurasia and pushing up the edge of the latter plate in the Alpine Orogeny of the Oligocene and Miocene Periods. Several microplates were caught in the squeeze and rotated or were pushed laterally, generating the individual features of Mediterranean geography: Iberia pushed up the Pyrenees; Italy, the Alps, and Anatolia, moving west, the mountains of Greece and the islands. The compression and orogeny continue today, as shown by the ongoing raising of the mountains a small amount each year and the active volcanoes.

When did the Jurassic Period end?


Read this: The mouth of the Rhine into Lake Constance forms an inland delta. The delta is delimited in the West by the Alter Rhein ("Old Rhine") and in the East by a modern canalized section. Most of the delta is a nature reserve and bird sanctuary. It includes the Austrian towns of Gaißau, Höchst and Fußach. The natural Rhine originally branched into at least two arms and formed small islands by precipitating sediments. In the local Alemannic dialect, the singular is pronounced "Isel" and this is also the local pronunciation of Esel ("Donkey"). Many local fields have an official name containing this element.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What animal sometimes swims in the Rhine?


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]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is a turbine's theoretical Carnot efficiency?


A large body of mathematical work would still be valid when calling 1 a prime, but Euclid's fundamental theorem of arithmetic (mentioned above) would not hold as stated. For example, the number 15 can be factored as 3 · 5 and 1 · 3 · 5; if 1 were admitted as a prime, these two presentations would be considered different factorizations of 15 into prime numbers, so the statement of that theorem would have to be modified. Similarly, the sieve of Eratosthenes would not work correctly if 1 were considered a prime: a modified version of the sieve that considers 1 as prime would eliminate all multiples of 1 (that is, all other numbers) and produce as output only the single number 1. Furthermore, the prime numbers have several properties that the number 1 lacks, such as the relationship of the number to its corresponding value of Euler's totient function or the sum of divisors function.
Try to answer this question if possible (otherwise reply "unanswerable"): Which theorem would be invalid if the number 1 were considered prime?


Like much of the south Atlantic region of the United States, Jacksonville has a humid subtropical climate (Köppen Cfa), with mild weather during winters and hot and humid weather during summers. Seasonal rainfall is concentrated in the warmest months from May through September, while the driest months are from November through April. Due to Jacksonville's low latitude and coastal location, the city sees very little cold weather, and winters are typically mild and sunny. Summers can be hot and wet, and summer thunderstorms with torrential but brief downpours are common.

Answer this question, if possible (if impossible, reply "unanswerable"): What is concentrated in the coldest months of the year?


Read this: Effects of inequality researchers have found include higher rates of health and social problems, and lower rates of social goods, a lower level of economic utility in society from resources devoted on high-end consumption, and even a lower level of economic growth when human capital is neglected for high-end consumption. For the top 21 industrialised countries, counting each person equally, life expectancy is lower in more unequal countries (r = -.907). A similar relationship exists among US states (r = -.620).

In U.S. states, what happens to the life expectancy in less economically equal ones?

Read this: When considering computational problems, a problem instance is a string over an alphabet. Usually, the alphabet is taken to be the binary alphabet (i.e., the set {0,1}), and thus the strings are bitstrings. As in a real-world computer, mathematical objects other than bitstrings must be suitably encoded. For example, integers can be represented in binary notation, and graphs can be encoded directly via their adjacency matrices, or by encoding their adjacency lists in binary.

Trade liberalization may shift economic inequality from a global to a domestic scale. When rich countries trade with poor countries, the low-skilled workers in the rich countries may see reduced wages as a result of the competition, while low-skilled workers in the poor countries may see increased wages. Trade economist Paul Krugman estimates that trade liberalisation has had a measurable effect on the rising inequality in the United States. He attributes this trend to increased trade with poor countries and the fragmentation of the means of production, resulting in low skilled jobs becoming more tradeable. However, he concedes that the effect of trade on inequality in America is minor when compared to other causes, such as technological innovation, a view shared by other experts. Empirical economists Max Roser and Jesus Crespo-Cuaresma find support in the data that international trade is increasing income inequality. They empirically confirm the predictions of the Stolper–Samuelson theorem regarding the effects of international trade on the distribution of incomes. Lawrence Katz estimates that trade has only accounted for 5-15% of rising income inequality. Robert Lawrence argues that technological innovation and automation has meant that low-skilled jobs have been replaced by machine labor in wealthier nations, and that wealthier countries no longer have significant numbers of low-skilled manufacturing workers that could be affected by competition from poor countries.

Answer this question, if possible (if impossible, reply "unanswerable"): Compared to other causes, the effect of trade on inequality in America is what?


The historian Francis Aidan Gasquet wrote about the 'Great Pestilence' in 1893 and suggested that "it would appear to be some form of the ordinary Eastern or bubonic plague". He was able to adopt the epidemiology of the bubonic plague for the Black Death for the second edition in 1908, implicating rats and fleas in the process, and his interpretation was widely accepted for other ancient and medieval epidemics, such as the Justinian plague that was prevalent in the Eastern Roman Empire from 541 to 700 CE.
Try to answer this question if possible (otherwise reply "unanswerable"): What did Gasquet think the plague was?


European Union law:

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

Please answer a question about this article. If the question is unanswerable, say "unanswerable". How many non paid holidays does the Working time directive require workers to have each year?


The University of Chicago also maintains facilities apart from its main campus. The university's Booth School of Business maintains campuses in Singapore, London, and the downtown Streeterville neighborhood of Chicago. The Center in Paris, a campus located on the left bank of the Seine in Paris, hosts various undergraduate and graduate study programs. In fall 2010, the University of Chicago also opened a center in Beijing, near Renmin University's campus in Haidian District. The most recent additions are a center in New Delhi, India, which opened in 2014, and a center in Hong Kong which opened in 2015.

Due to its electronegativity, oxygen forms chemical bonds with almost all other elements to give corresponding oxides. The surface of most metals, such as aluminium and titanium, are oxidized in the presence of air and become coated with a thin film of oxide that passivates the metal and slows further corrosion. Many oxides of the transition metals are non-stoichiometric compounds, with slightly less metal than the chemical formula would show. For example, the mineral FeO (wüstite) is written as Fe
1 − xO, where x is usually around 0.05.

What is the mineral wustite?

Warsaw (Polish: Warszawa [varˈʂava] ( listen); see also other names) is the capital and largest city of Poland. It stands on the Vistula River in east-central Poland, roughly 260 kilometres (160 mi) from the Baltic Sea and 300 kilometres (190 mi) from the Carpathian Mountains. Its population is estimated at 1.740 million residents within a greater metropolitan area of 2.666 million residents, which makes Warsaw the 9th most-populous capital city in the European Union. The city limits cover 516.9 square kilometres (199.6 sq mi), while the metropolitan area covers 6,100.43 square kilometres (2,355.39 sq mi).

On what river does Warsaw stand?


On the other hand, in the late 1980s the Western Atlantic ctenophore Mnemiopsis leidyi was accidentally introduced into the Black Sea and Sea of Azov via the ballast tanks of ships, and has been blamed for causing sharp drops in fish catches by eating both fish larvae and small crustaceans that would otherwise feed the adult fish. Mnemiopsis is well equipped to invade new territories (although this was not predicted until after it so successfully colonized the Black Sea), as it can breed very rapidly and tolerate a wide range of water temperatures and salinities. The impact was increased by chronic overfishing, and by eutrophication that gave the entire ecosystem a short-term boost, causing the Mnemiopsis population to increase even faster than normal – and above all by the absence of efficient predators on these introduced ctenophores. Mnemiopsis populations in those areas were eventually brought under control by the accidental introduction of the Mnemiopsis-eating North American ctenophore Beroe ovata, and by a cooling of the local climate from 1991 to 1993, which significantly slowed the animal's metabolism. However the abundance of plankton in the area seems unlikely to be restored to pre-Mnemiopsis levels.

The British failures in North America, combined with other failures in the European theater, led to the fall from power of Newcastle and his principal military advisor, the Duke of Cumberland. Newcastle and Pitt joined in an uneasy coalition in which Pitt dominated the military planning. He embarked on a plan for the 1758 campaign that was largely developed by Loudoun. He had been replaced by Abercrombie as commander in chief after the failures of 1757. Pitt's plan called for three major offensive actions involving large numbers of regular troops, supported by the provincial militias, aimed at capturing the heartlands of New France. Two of the expeditions were successful, with Fort Duquesne and Louisbourg falling to sizable British forces.
Try to answer this question if possible (otherwise reply "unanswerable"): How many of the Pitt's planned expeditions weren't successful?


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.

Black Death:

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

When some species, including Bathyctena chuni, Euplokamis stationis and Eurhamphaea vexilligera, are disturbed, they produce secretions (ink) that luminesce at much the same wavelengths as their bodies. Juveniles will luminesce more brightly in relation to their body size than adults, whose luminescence is diffused over their bodies. Detailed statistical investigation has not suggested the function of ctenophores' bioluminescence nor produced any correlation between its exact color and any aspect of the animals' environments, such as depth or whether they live in coastal or mid-ocean waters.

Answer this question, if possible (if impossible, reply "unanswerable"): Do adults or juveniles secretions luminesce brighter?


Read this: To measure the difficulty of solving a computational problem, one may wish to see how much time the best algorithm requires to solve the problem. However, the running time may, in general, depend on the instance. In particular, larger instances will require more time to solve. Thus the time required to solve a problem (or the space required, or any measure of complexity) is calculated as a function of the size of the instance. This is usually taken to be the size of the input in bits. Complexity theory is interested in how algorithms scale with an increase in the input size. For instance, in the problem of finding whether a graph is connected, how much more time does it take to solve a problem for a graph with 2n vertices compared to the time taken for a graph with n vertices?
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What is a commonly used measurement used to determine the complexity of a computational problem?


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

The mermaid (syrenka) is Warsaw's symbol and can be found on statues throughout the city and on the city's coat of arms. This imagery has been in use since at least the mid-14th century. The oldest existing armed seal of Warsaw is from the year 1390, consisting of a round seal bordered with the Latin inscription Sigilium Civitatis Varsoviensis (Seal of the city of Warsaw). City records as far back as 1609 document the use of a crude form of a sea monster with a female upper body and holding a sword in its claws. In 1653 the poet Zygmunt Laukowski asks the question:

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.

Answer this question, if possible (if impossible, reply "unanswerable"): In what year did William Maclure begin the process of creating the first geological map of the U.S.?


Immune system:

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

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What was suggested in immunology before the 19th century?


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


French Huguenots made two attempts to establish a haven in North America. In 1562, naval officer Jean Ribault led an expedition that explored Florida and the present-day Southeastern U.S., and founded the outpost of Charlesfort on Parris Island, South Carolina. The Wars of Religion precluded a return voyage, and the outpost was abandoned. In 1564, Ribault's former lieutenant René Goulaine de Laudonnière launched a second voyage to build a colony; he established Fort Caroline in what is now Jacksonville, Florida. War at home again precluded a resupply mission, and the colony struggled. In 1565 the Spanish decided to enforce their claim to La Florida, and sent Pedro Menéndez de Avilés, who established the settlement of St. Augustine near Fort Caroline. Menéndez' forces routed the French and executed most of the Protestant captives.
Try to answer this question if possible (otherwise reply "unanswerable"): What European event caused the Huguenots to abandon Charlesfort?


Construction:

Construction is one of the most dangerous occupations in the world, incurring more occupational fatalities than any other sector in both the United States and in the European Union. In 2009, the fatal occupational injury rate among construction workers in the United States was nearly three times that for all workers. Falls are one of the most common causes of fatal and non-fatal injuries among construction workers. Proper safety equipment such as harnesses and guardrails and procedures such as securing ladders and inspecting scaffolding can curtail the risk of occupational injuries in the construction industry. Other major causes of fatalities in the construction industry include electrocution, transportation accidents, and trench cave-ins.

Black Death:

The plague struck various countries in the Middle East during the pandemic, leading to serious depopulation and permanent change in both economic and social structures. As it spread to western Europe, the disease entered the region from southern Russia also. By autumn 1347, the plague reached Alexandria in Egypt, probably through the port's trade with Constantinople, and ports on the Black Sea. During 1347, the disease travelled eastward to Gaza, and north along the eastern coast to cities in Lebanon, Syria and Palestine, including Ashkelon, Acre, Jerusalem, Sidon, Damascus, Homs, and Aleppo. In 1348–49, the disease reached Antioch. The city's residents fled to the north, most of them dying during the journey, but the infection had been spread to the people of Asia Minor.[citation needed]

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.

Steam engines frequently possess two independent mechanisms for ensuring that the pressure in the boiler does not go too high; one may be adjusted by the user, the second is typically designed as an ultimate fail-safe. Such safety valves traditionally used a simple lever to restrain a plug valve in the top of a boiler. One end of the lever carried a weight or spring that restrained the valve against steam pressure. Early valves could be adjusted by engine drivers, leading to many accidents when a driver fastened the valve down to allow greater steam pressure and more power from the engine. The more recent type of safety valve uses an adjustable spring-loaded valve, which is locked such that operators may not tamper with its adjustment unless a seal illegally is broken. This arrangement is considerably safer.[citation needed]

What is restrained with a lever in the top of a driver?


Leukocytes (white blood cells) act like independent, single-celled organisms and are the second arm of the innate immune system. The innate leukocytes include the phagocytes (macrophages, neutrophils, and dendritic cells), mast cells, eosinophils, basophils, and natural killer cells. These cells identify and eliminate pathogens, either by attacking larger pathogens through contact or by engulfing and then killing microorganisms. Innate cells are also important mediators in the activation of the adaptive immune system.

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

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.

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

What do petrologists use to understand magma chamber crystallization?


Computational complexity theory:

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

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What does not induce a proper hierarchy on the classes defined by constraining the respective resources?


IPCC author Richard Lindzen has made a number of criticisms of the TAR. Among his criticisms, Lindzen has stated that the WGI Summary for Policymakers (SPM) does not faithfully summarize the full WGI report. For example, Lindzen states that the SPM understates the uncertainty associated with climate models. John Houghton, who was a co-chair of TAR WGI, has responded to Lindzen's criticisms of the SPM. Houghton has stressed that the SPM is agreed upon by delegates from many of the world's governments, and that any changes to the SPM must be supported by scientific evidence.

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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year did the Mongol conquest of China begin?


Read this: Hormones can act as immunomodulators, altering the sensitivity of the immune system. For example, female sex hormones are known immunostimulators of both adaptive and innate immune responses. Some autoimmune diseases such as lupus erythematosus strike women preferentially, and their onset often coincides with puberty. By contrast, male sex hormones such as testosterone seem to be immunosuppressive. Other hormones appear to regulate the immune system as well, most notably prolactin, growth hormone and vitamin D.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Female sex hormones are immunostimulators of which immune responses?

A procedural consequence of the establishment of the Scottish Parliament is that Scottish MPs sitting in the UK House of Commons are able to vote on domestic legislation that applies only to England, Wales and Northern Ireland – whilst English, Scottish, Welsh and Northern Irish Westminster MPs are unable to vote on the domestic legislation of the Scottish Parliament. This phenomenon is known as the West Lothian question and has led to criticism. Following the Conservative victory in the 2015 UK election, standing orders of the House of Commons were changed to give MPs representing English constituencies a new "veto" over laws only affecting England.

MPs representing English constituencies can only veto laws affecting which country?


According to the United States Census Bureau, the city has a total area of 874.3 square miles (2,264 km2), making Jacksonville the largest city in land area in the contiguous United States; of this, 86.66% (757.7 sq mi or 1,962 km2) is land and ; 13.34% (116.7 sq mi or 302 km2) is water. Jacksonville surrounds the town of Baldwin. Nassau County lies to the north, Baker County lies to the west, and Clay and St. Johns County lie to the south; the Atlantic Ocean lies to the east, along with the Jacksonville Beaches. The St. Johns River divides the city. The Trout River, a major tributary of the St. Johns River, is located entirely within Jacksonville.

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

The election produced a majority SNP government, making this the first time in the Scottish Parliament where a party has commanded a parliamentary majority. The SNP took 16 seats from Labour, with many of their key figures not returned to parliament, although Labour leader Iain Gray retained East Lothian by 151 votes. The SNP took a further eight seats from the Liberal Democrats and one seat from the Conservatives. The SNP overall majority meant that there was sufficient support in the Scottish Parliament to hold a referendum on Scottish independence.

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:

Computational complexity theory:

The complexity class P is often seen as a mathematical abstraction modeling those computational tasks that admit an efficient algorithm. This hypothesis is called the Cobham–Edmonds thesis. The complexity class NP, on the other hand, contains many problems that people would like to solve efficiently, but for which no efficient algorithm is known, such as the Boolean satisfiability problem, the Hamiltonian path problem and the vertex cover problem. Since deterministic Turing machines are special non-deterministic Turing machines, it is easily observed that each problem in P is also member of the class NP.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What theory is the Cobham-Edward thesis?


During the 1970s and sometimes later, Western and pro-Western governments often supported sometimes fledgling Islamists and Islamist groups that later came to be seen as dangerous enemies. Islamists were considered by Western governments bulwarks against—what were thought to be at the time—more dangerous leftist/communist/nationalist insurgents/opposition, which Islamists were correctly seen as opposing. The US spent billions of dollars to aid the mujahideen Muslim Afghanistan enemies of the Soviet Union, and non-Afghan veterans of the war returned home with their prestige, "experience, ideology, and weapons", and had considerable impact.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who did the US provide aid to, to fight against the Soviet Union?


During the mass high school education movement from 1910–1940, there was an increase in skilled workers, which led to a decrease in the price of skilled labor. High school education during the period was designed to equip students with necessary skill sets to be able to perform at work. In fact, it differs from the present high school education, which is regarded as a stepping-stone to acquire college and advanced degrees. This decrease in wages caused a period of compression and decreased inequality between skilled and unskilled workers. Education is very important for the growth of the economy, however educational inequality in gender also influence towards the economy. Lagerlof and Galor stated that gender inequality in education can result to low economic growth, and continued gender inequality in education, thus creating a poverty trap. It is suggested that a large gap in male and female education may indicate backwardness and so may be associated with lower economic growth, which can explain why there is economic inequality between countries.
What impact did the high school education movement have on the wages of unskilled workers? (If the question is unanswerable, say "unanswerable")


Read this: In 1564 a group of Norman Huguenots under the leadership of Jean Ribault established the small colony of Fort Caroline on the banks of the St. Johns River in what is today Jacksonville, Florida. The effort was the first at any permanent European settlement in the present-day continental United States, but survived only a short time. A September 1565 French naval attack against the new Spanish colony at St. Augustine failed when its ships were hit by a hurricane on their way to the Spanish encampment at Fort Matanzas. Hundreds of French soldiers were stranded and surrendered to the numerically inferior Spanish forces led by Pedro Menendez. Menendez proceeded to massacre the defenseless Huguenots, after which he wiped out the Fort Caroline garrison.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): When was the colony destroyed?

Read this: Construction is one of the most dangerous occupations in the world, incurring more occupational fatalities than any other sector in both the United States and in the European Union. In 2009, the fatal occupational injury rate among construction workers in the United States was nearly three times that for all workers. Falls are one of the most common causes of fatal and non-fatal injuries among construction workers. Proper safety equipment such as harnesses and guardrails and procedures such as securing ladders and inspecting scaffolding can curtail the risk of occupational injuries in the construction industry. Other major causes of fatalities in the construction industry include electrocution, transportation accidents, and trench cave-ins.

Read this: Norman architecture typically stands out as a new stage in the architectural history of the regions they subdued. They spread a unique Romanesque idiom to England and Italy, and the encastellation of these regions with keeps in their north French style fundamentally altered the military landscape. Their style was characterised by rounded arches, particularly over windows and doorways, and massive proportions.

The principal Treaties that form the European Union began with common rules for coal and steel, and then atomic energy, but more complete and formal institutions were established through the Treaty of Rome 1957 and the Maastricht Treaty 1992 (now: TFEU). Minor amendments were made during the 1960s and 1970s. Major amending treaties were signed to complete the development of a single, internal market in the Single European Act 1986, to further the development of a more social Europe in the Treaty of Amsterdam 1997, and to make minor amendments to the relative power of member states in the EU institutions in the Treaty of Nice 2001 and the Treaty of Lisbon 2007. Since its establishment, more member states have joined through a series of accession treaties, from the UK, Ireland, Denmark and Norway in 1972 (though Norway did not end up joining), Greece in 1979, Spain and Portugal 1985, Austria, Finland, Norway and Sweden in 1994 (though again Norway failed to join, because of lack of support in the referendum), the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia in 2004, Romania and Bulgaria in 2007 and Croatia in 2013. Greenland signed a Treaty in 1985 giving it a special status.

Read this: Often rules apply to all goods neutrally, but may have a greater practical effect on imports than domestic products. For such "indirect" discriminatory (or "indistinctly applicable") measures the Court of Justice has developed more justifications: either those in article 36, or additional "mandatory" or "overriding" requirements such as consumer protection, improving labour standards, protecting the environment, press diversity, fairness in commerce, and more: the categories are not closed. In the most famous case Rewe-Zentral AG v Bundesmonopol für Branntwein, the Court of Justice found that a German law requiring all spirits and liqueurs (not just imported ones) to have a minimum alcohol content of 25 per cent was contrary to TFEU article 34, because it had a greater negative effect on imports. German liqueurs were over 25 per cent alcohol, but Cassis de Dijon, which Rewe-Zentrale AG wished to import from France, only had 15 to 20 per cent alcohol. The Court of Justice rejected the German government's arguments that the measure proportionately protected public health under TFEU article 36, because stronger beverages were available and adequate labelling would be enough for consumers to understand what they bought. This rule primarily applies to requirements about a product's content or packaging. In Walter Rau Lebensmittelwerke v De Smedt PVBA the Court of Justice found that a Belgian law requiring all margarine to be in cube shaped packages infringed article 34, and was not justified by the pursuit of consumer protection. The argument that Belgians would believe it was butter if it was not cube shaped was disproportionate: it would "considerably exceed the requirements of the object in view" and labelling would protect consumers "just as effectively". In a 2003 case, Commission v Italy Italian law required that cocoa products that included other vegetable fats could not be labelled as "chocolate". It had to be "chocolate substitute". All Italian chocolate was made from cocoa butter alone, but British, Danish and Irish manufacturers used other vegetable fats. They claimed the law infringed article 34. The Court of Justice held that a low content of vegetable fat did not justify a "chocolate substitute" label. This was derogatory in the consumers' eyes. A ‘neutral and objective statement’ was enough to protect consumers. If member states place considerable obstacles on the use of a product, this can also infringe article 34. So, in a 2009 case, Commission v Italy, the Court of Justice held that an Italian law prohibiting motorcycles or mopeds pulling trailers infringed article 34. Again, the law applied neutrally to everyone, but disproportionately affected importers, because Italian companies did not make trailers. This was not a product requirement, but the Court reasoned that the prohibition would deter people from buying it: it would have "a considerable influence on the behaviour of consumers" that "affects the access of that product to the market". It would require justification under article 36, or as a mandatory requirement.

To help reduce consumption, in 1974 a national maximum speed limit of 55 mph (about 88 km/h) was imposed through the Emergency Highway Energy Conservation Act. Development of the Strategic Petroleum Reserve began in 1975, and in 1977 the cabinet-level Department of Energy was created, followed by the National Energy Act of 1978.[citation needed] On November 28, 1995, Bill Clinton signed the National Highway Designation Act, ending the federal 55 mph (89 km/h) speed limit, allowing states to restore their prior maximum speed limit.

On Novermber 28, 1995 what did the Department of Energy end?


Read this: Connection-oriented transmission requires a setup phase in each involved node before any packet is transferred to establish the parameters of communication. The packets include a connection identifier rather than address information and are negotiated between endpoints so that they are delivered in order and with error checking. Address information is only transferred to each node during the connection set-up phase, when the route to the destination is discovered and an entry is added to the switching table in each network node through which the connection passes. The signaling protocols used allow the application to specify its requirements and discover link parameters. Acceptable values for service parameters may be negotiated. Routing a packet requires the node to look up the connection id in a table. The packet header can be small, as it only needs to contain this code and any information, such as length, timestamp, or sequence number, which is different for different packets.

What does the address information negotiate?

This means that in a closed system of particles, there are no internal forces that are unbalanced. That is, the action-reaction force shared between any two objects in a closed system will not cause the center of mass of the system to accelerate. The constituent objects only accelerate with respect to each other, the system itself remains unaccelerated. Alternatively, if an external force acts on the system, then the center of mass will experience an acceleration proportional to the magnitude of the external force divided by the mass of the system.:19-1

In what kind of system of particles are there no unbalanced iinternal forces?


The mermaid (syrenka) is Warsaw's symbol and can be found on statues throughout the city and on the city's coat of arms. This imagery has been in use since at least the mid-14th century. The oldest existing armed seal of Warsaw is from the year 1390, consisting of a round seal bordered with the Latin inscription Sigilium Civitatis Varsoviensis (Seal of the city of Warsaw). City records as far back as 1609 document the use of a crude form of a sea monster with a female upper body and holding a sword in its claws. In 1653 the poet Zygmunt Laukowski asks the question:

In 2014, economists with the Standard & Poor's rating agency concluded that the widening disparity between the U.S.'s wealthiest citizens and the rest of the nation had slowed its recovery from the 2008-2009 recession and made it more prone to boom-and-bust cycles. To partially remedy the wealth gap and the resulting slow growth, S&P recommended increasing access to education. It estimated that if the average United States worker had completed just one more year of school, it would add an additional $105 billion in growth to the country's economy over five years.

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."

Both innate and adaptive immunity depend on the ability of the immune system to distinguish between self and non-self molecules. In immunology, self molecules are those components of an organism's body that can be distinguished from foreign substances by the immune system. Conversely, non-self molecules are those recognized as foreign molecules. One class of non-self molecules are called antigens (short for antibody generators) and are defined as substances that bind to specific immune receptors and elicit an immune response.

Since ~3000 yr BP (= years Before Present), human impact is seen in the delta. As a result of increasing land clearance (Bronze Age agriculture), in the upland areas (central Germany), the sediment load of the Rhine has strongly increased and delta growth has sped up. This caused increased flooding and sedimentation, ending peat formation in the delta. The shifting of river channels to new locations, on the floodplain (termed avulsion), was the main process distributing sediment across the subrecent delta. Over the past 6000 years, approximately 80 avulsions have occurred. Direct human impact in the delta started with peat mining, for salt and fuel, from Roman times onward. This was followed by embankment, of the major distributaries and damming of minor distributaries, which took place in the 11–13th century AD. Thereafter, canals were dug, bends were short cut and groynes were built, to prevent the river's channels from migrating or silting up.

What has increased sediment and delta growth also produced in the Rhine?
