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

Read this: 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.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What period did plates reverse directions to compress the Tethys floor?


Construction is the process of constructing a building or infrastructure. Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client. Construction as an industry comprises six to nine percent of the gross domestic product of developed countries. Construction starts with planning,[citation needed] design, and financing and continues until the project is built and ready for use.
Try to answer this question if possible (otherwise reply "unanswerable"): What three things are recommended before construction begins?


In 1846, the natural history lectures of Louis Agassiz were acclaimed both in New York and on the campus at Harvard College. Agassiz's approach was distinctly idealist and posited Americans' "participation in the Divine Nature" and the possibility of understanding "intellectual existences". Agassiz's perspective on science combined observation with intuition and the assumption that a person can grasp the "divine plan" in all phenomena. When it came to explaining life-forms, Agassiz resorted to matters of shape based on a presumed archetype for his evidence. This dual view of knowledge was in concert with the teachings of Common Sense Realism derived from Scottish philosophers Thomas Reid and Dugald Stewart, whose works were part of the Harvard curriculum at the time. The popularity of Agassiz's efforts to "soar with Plato" probably also derived from other writings to which Harvard students were exposed, including Platonic treatises by Ralph Cudworth, John Norrisand, in a Romantic vein, Samuel Coleridge. The library records at Harvard reveal that the writings of Plato and his early modern and Romantic followers were almost as regularly read during the 19th century as those of the "official philosophy" of the more empirical and more deistic Scottish school.

It has been argued that the term "civil disobedience" has always suffered from ambiguity and in modern times, become utterly debased. Marshall Cohen notes, "It has been used to describe everything from bringing a test-case in the federal courts to taking aim at a federal official. Indeed, for Vice President Agnew it has become a code-word describing the activities of muggers, arsonists, draft evaders, campaign hecklers, campus militants, anti-war demonstrators, juvenile delinquents and political assassins."

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

The addition of new rock units, both depositionally and intrusively, often occurs during deformation. Faulting and other deformational processes result in the creation of topographic gradients, causing material on the rock unit that is increasing in elevation to be eroded by hillslopes and channels. These sediments are deposited on the rock unit that is going down. Continual motion along the fault maintains the topographic gradient in spite of the movement of sediment, and continues to create accommodation space for the material to deposit. Deformational events are often also associated with volcanism and igneous activity. Volcanic ashes and lavas accumulate on the surface, and igneous intrusions enter from below. Dikes, long, planar igneous intrusions, enter along cracks, and therefore often form in large numbers in areas that are being actively deformed. This can result in the emplacement of dike swarms, such as those that are observable across the Canadian shield, or rings of dikes around the lava tube of a volcano.

What two types of activity are associated with the Canadian shield?

Around 1800 Richard Trevithick and, separately, Oliver Evans in 1801 introduced engines using high-pressure steam; Trevithick obtained his high-pressure engine patent in 1802. These were much more powerful for a given cylinder size than previous engines and could be made small enough for transport applications. Thereafter, technological developments and improvements in manufacturing techniques (partly brought about by the adoption of the steam engine as a power source) resulted in the design of more efficient engines that could be smaller, faster, or more powerful, depending on the intended application.

Who invented a high-pressure steam engine around 1800?


European Union law:

Following the Nice Treaty, there was an attempt to reform the constitutional law of the European Union and make it more transparent; this would have also produced a single constitutional document. However, as a result of the referendum in France and the referendum in the Netherlands, the 2004 Treaty establishing a Constitution for Europe never came into force. Instead, the Lisbon Treaty was enacted. Its substance was very similar to the proposed constitutional treaty, but it was formally an amending treaty, and – though it significantly altered the existing treaties – it did not completely replace them.

Following the Peterloo massacre of 1819, poet Percy Shelley wrote the political poem The Mask of Anarchy later that year, that begins with the images of what he thought to be the unjust forms of authority of his time—and then imagines the stirrings of a new form of social action. It is perhaps the first modern[vague] statement of the principle of nonviolent protest. A version was taken up by the author Henry David Thoreau in his essay Civil Disobedience, and later by Gandhi in his doctrine of Satyagraha. Gandhi's Satyagraha was partially influenced and inspired by Shelley's nonviolence in protest and political action. In particular, it is known that Gandhi would often quote Shelley's Masque of Anarchy to vast audiences during the campaign for a free India.

Sessions of the IPCC Bureau, workshops, expert and lead authors meetings are by invitation only. Attendance at the 2003 meeting included 350 government officials and climate change experts. After the opening ceremonies, closed plenary sessions were held. The meeting report states there were 322 persons in attendance at Sessions with about seven-eighths of participants being from governmental organizations.

Answer this question, if possible (if impossible, reply "unanswerable"): What session did the IPCC panel attend before the opening ceremonies?


The French acquired a copy of the British war plans, including the activities of Shirley and Johnson. Shirley's efforts to fortify Oswego were bogged down in logistical difficulties, exacerbated by Shirley's inexperience in managing large expeditions. In conjunction, Shirley was made aware that the French were massing for an attack on Fort Oswego in his absence when he planned to attack Fort Niagara. As a response, Shirley left garrisons at Oswego, Fort Bull, and Fort Williams (the latter two located on the Oneida Carry between the Mohawk River and Wood Creek at present-day Rome, New York). Supplies for use in the projected attack on Niagara were cached at Fort Bull.

Read this: A regulation of the Rhine was called for, with an upper canal near Diepoldsau and a lower canal at Fußach, in order to counteract the constant flooding and strong sedimentation in the western Rhine Delta. The Dornbirner Ach had to be diverted, too, and it now flows parallel to the canalized Rhine into the lake. Its water has a darker color than the Rhine; the latter's lighter suspended load comes from higher up the mountains. It is expected that the continuous input of sediment into the lake will silt up the lake. This has already happened to the former Lake Tuggenersee.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What is expected with the continuous input of sediment into the Dornbirner Ach?


Following a referendum in 1997, in which the Scottish electorate voted for devolution, the current Parliament was convened by the Scotland Act 1998, which sets out its powers as a devolved legislature. The Act delineates the legislative competence of the Parliament – the areas in which it can make laws – by explicitly specifying powers that are "reserved" to the Parliament of the United Kingdom. The Scottish Parliament has the power to legislate in all areas that are not explicitly reserved to Westminster. The British Parliament retains the ability to amend the terms of reference of the Scottish Parliament, and can extend or reduce the areas in which it can make laws. The first meeting of the new Parliament took place on 12 May 1999.
Try to answer this question if possible (otherwise reply "unanswerable"): When was the current parliament of Scotland convened?


Read this: A few years after the First Crusade, in 1107, the Normans under the command of Bohemond, Robert's son, landed in Valona and besieged Dyrrachium using the most sophisticated military equipment of the time, but to no avail. Meanwhile, they occupied Petrela, the citadel of Mili at the banks of the river Deabolis, Gllavenica (Ballsh), Kanina and Jericho. This time, the Albanians sided with the Normans, dissatisfied by the heavy taxes the Byzantines had imposed upon them. With their help, the Normans secured the Arbanon passes and opened their way to Dibra. The lack of supplies, disease and Byzantine resistance forced Bohemond to retreat from his campaign and sign a peace treaty with the Byzantines in the city of Deabolis.

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.
What trend increases the organic composition of capital over the long term? (If the question is unanswerable, say "unanswerable")


Read this: The historical measure of a steam engine's energy efficiency was its "duty". The concept of duty was first introduced by Watt in order to illustrate how much more efficient his engines were over the earlier Newcomen designs. Duty is the number of foot-pounds of work delivered by burning one bushel (94 pounds) of coal. The best examples of Newcomen designs had a duty of about 7 million, but most were closer to 5 million. Watt's original low-pressure designs were able to deliver duty as high as 25 million, but averaged about 17. This was a three-fold improvement over the average Newcomen design. Early Watt engines equipped with high-pressure steam improved this to 65 million.

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

Answer this question, if possible (if impossible, reply "unanswerable"): When an activated killer T cell finds cells where the MHC 1 receptor has specific antigens, it releases cytotoxins such as what?


Dendritic cells (DC) are phagocytes in tissues that are in contact with the external environment; therefore, they are located mainly in the skin, nose, lungs, stomach, and intestines. They are named for their resemblance to neuronal dendrites, as both have many spine-like projections, but dendritic cells are in no way connected to the nervous system. Dendritic cells serve as a link between the bodily tissues and the innate and adaptive immune systems, as they present antigens to T cells, one of the key cell types of the adaptive immune system.

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.)

In 1529, Warsaw for the first time became the seat of the General Sejm, permanent from 1569. In 1573 the city gave its name to the Warsaw Confederation, formally establishing religious freedom in the Polish–Lithuanian Commonwealth. Due to its central location between the Commonwealth's capitals of Kraków and Vilnius, Warsaw became the capital of the Commonwealth and the Crown of the Kingdom of Poland when King Sigismund III Vasa moved his court from Kraków to Warsaw in 1596. In the following years the town expanded towards the suburbs. Several private independent districts were established, the property of aristocrats and the gentry, which were ruled by their own laws. Three times between 1655–1658 the city was under siege and three times it was taken and pillaged by the Swedish, Brandenburgian and Transylvanian forces.

Read this: Hence, 6 is not prime. The image at the right illustrates that 12 is not prime: 12 = 3 · 4. No even number greater than 2 is prime because by definition, any such number n has at least three distinct divisors, namely 1, 2, and n. This implies that n is not prime. Accordingly, the term odd prime refers to any prime number greater than 2. Similarly, when written in the usual decimal system, all prime numbers larger than 5 end in 1, 3, 7, or 9, since even numbers are multiples of 2 and numbers ending in 0 or 5 are multiples of 5.

A simple case of dynamic equilibrium occurs in constant velocity motion across a surface with kinetic friction. In such a situation, a force is applied in the direction of motion while the kinetic friction force exactly opposes the applied force. This results in zero net force, but since the object started with a non-zero velocity, it continues to move with a non-zero velocity. Aristotle misinterpreted this motion as being caused by the applied force. However, when kinetic friction is taken into consideration it is clear that there is no net force causing constant velocity motion.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who thought that applied force caused movement of an object regardless of non-zero velocity?

Fresno is the largest U.S. city not directly linked to an Interstate highway. When the Interstate Highway System was created in the 1950s, the decision was made to build what is now Interstate 5 on the west side of the Central Valley, and thus bypass many of the population centers in the region, instead of upgrading what is now State Route 99. Due to rapidly raising population and traffic in cities along SR 99, as well as the desirability of Federal funding, much discussion has been made to upgrade it to interstate standards and eventually incorporate it into the interstate system, most likely as Interstate 9. Major improvements to signage, lane width, median separation, vertical clearance, and other concerns are currently underway.

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

On October 6, 1973, Syria and Egypt, with support from other Arab nations, launched a surprise attack on Israel, on Yom Kippur. This renewal of hostilities in the Arab–Israeli conflict released the underlying economic pressure on oil prices. At the time, Iran was the world's second-largest oil exporter and a close US ally. Weeks later, the Shah of Iran said in an interview: "Of course [the price of oil] is going to rise... Certainly! And how!... You've [Western nations] increased the price of the wheat you sell us by 300 percent, and the same for sugar and cement... You buy our crude oil and sell it back to us, refined as petrochemicals, at a hundred times the price you've paid us... It's only fair that, from now on, you should pay more for oil. Let's say ten times more."

Iran was which size oil exporter?


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

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

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.

Traditionally, Labor is strongest in Melbourne's working class western and northern suburbs, and the regional cities of Ballarat, Bendigo and Geelong. The Liberals' main support lies in Melbourne's more affluent eastern and outer suburbs, and some rural and regional centres. The Nationals are strongest in Victoria's North Western and Eastern rural regional areas. The Greens, who won their first lower house seats in 2014, are strongest in inner Melbourne.

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

 When was the military-political complex reflected upon not within the scope of understanding imperialism?


Read this: French Huguenot explorer Jean Ribault charted the St. Johns River in 1562 calling it the River of May because he discovered it in May. Ribault erected a stone column near present-day Jacksonville claiming the newly discovered land for France. In 1564, René Goulaine de Laudonnière established the first European settlement, Fort Caroline, on the St. Johns near the main village of the Saturiwa. Philip II of Spain ordered Pedro Menéndez de Avilés to protect the interest of Spain by attacking the French presence at Fort Caroline. On September 20, 1565, a Spanish force from the nearby Spanish settlement of St. Augustine attacked Fort Caroline, and killed nearly all the French soldiers defending it. The Spanish renamed the fort San Mateo, and following the ejection of the French, St. Augustine's position as the most important settlement in Florida was solidified. The location of Fort Caroline is subject to debate but a reconstruction of the fort was established on the St. Johns River in 1964.

Ranging from about 1 millimeter (0.039 in) to 1.5 meters (4.9 ft) in size, ctenophores are the largest non-colonial animals that use cilia ("hairs") as their main method of locomotion. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb-like bands of cilia, called "ctenes," stacked along the comb rows so that when the cilia beat, those of each comb touch the comb below. The name "ctenophora" means "comb-bearing", from the Greek κτείς (stem-form κτεν-) meaning "comb" and the Greek suffix -φορος meaning "carrying".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What kind of animals are cilia considered?


Warsaw:

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.

Packet switching:

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

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Can a packet be lost and if so, then where does it go?


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.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Can packets ever collide in route?

In one experiment, Lavoisier observed that there was no overall increase in weight when tin and air were heated in a closed container. He noted that air rushed in when he opened the container, which indicated that part of the trapped air had been consumed. He also noted that the tin had increased in weight and that increase was the same as the weight of the air that rushed back in. This and other experiments on combustion were documented in his book Sur la combustion en général, which was published in 1777. In that work, he proved that air is a mixture of two gases; 'vital air', which is essential to combustion and respiration, and azote (Gk. ἄζωτον "lifeless"), which did not support either. Azote later became nitrogen in English, although it has kept the name in French and several other European languages.

In what way did Lavoisier see that the tin he used in his experiment had increased?


The first commercially successful true engine, in that it could generate power and transmit it to a machine, was the atmospheric engine, invented by Thomas Newcomen around 1712. It was an improvement over Savery's steam pump, using a piston as proposed by Papin. Newcomen's engine was relatively inefficient, and in most cases was used for pumping water. It worked by creating a partial vacuum by condensing steam under a piston within a cylinder. It was employed for draining mine workings at depths hitherto impossible, and also for providing a reusable water supply for driving waterwheels at factories sited away from a suitable "head". Water that had passed over the wheel was pumped back up into a storage reservoir above the wheel.
What was the first true vacuum that was commercially successful? (If the question is unanswerable, say "unanswerable")


Breathing pure O
2 in space applications, such as in some modern space suits, or in early spacecraft such as Apollo, causes no damage due to the low total pressures used. In the case of spacesuits, the O
2 partial pressure in the breathing gas is, in general, about 30 kPa (1.4 times normal), and the resulting O
2 partial pressure in the astronaut's arterial blood is only marginally more than normal sea-level O
2 partial pressure (for more information on this, see space suit and arterial blood gas).

LeGrande writes that "the formulation of a single all-encompassing definition of the term is extremely difficult, if not impossible. In reviewing the voluminous literature on the subject, the student of civil disobedience rapidly finds himself surrounded by a maze of semantical problems and grammatical niceties. Like Alice in Wonderland, he often finds that specific terminology has no more (or no less) meaning than the individual orator intends it to have." He encourages a distinction between lawful protest demonstration, nonviolent civil disobedience, and violent civil disobedience.

What issue plagues the literature about civil disobedience?


Highly concentrated sources of oxygen promote rapid combustion. Fire and explosion hazards exist when concentrated oxidants and fuels are brought into close proximity; an ignition event, such as heat or a spark, is needed to trigger combustion. Oxygen is the oxidant, not the fuel, but nevertheless the source of most of the chemical energy released in combustion. Combustion hazards also apply to compounds of oxygen with a high oxidative potential, such as peroxides, chlorates, nitrates, perchlorates, and dichromates because they can donate oxygen to a fire.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can concentrated oxygen produce?


Read this: Prior to European settlement, the area now constituting Victoria was inhabited by a large number of Aboriginal peoples, collectively known as the Koori. With Great Britain having claimed the entire Australian continent east of the 135th meridian east in 1788, Victoria was included in the wider colony of New South Wales. The first settlement in the area occurred in 1803 at Sullivan Bay, and much of what is now Victoria was included in the Port Phillip District in 1836, an administrative division of New South Wales. Victoria was officially created a separate colony in 1851, and achieved self-government in 1855. The Victorian gold rush in the 1850s and 1860s significantly increased both the population and wealth of the colony, and by the Federation of Australia in 1901, Melbourne had become the largest city and leading financial centre in Australasia. Melbourne also served as capital of Australia until the construction of Canberra in 1927, with the Federal Parliament meeting in Melbourne's Parliament House and all principal offices of the federal government being based in Melbourne.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What is the term for the original Aboriginal people of Victoria?


Among the most well-known experiments in structural geology are those involving orogenic wedges, which are zones in which mountains are built along convergent tectonic plate boundaries. In the analog versions of these experiments, horizontal layers of sand are pulled along a lower surface into a back stop, which results in realistic-looking patterns of faulting and the growth of a critically tapered (all angles remain the same) orogenic wedge. Numerical models work in the same way as these analog models, though they are often more sophisticated and can include patterns of erosion and uplift in the mountain belt. This helps to show the relationship between erosion and the shape of the mountain range. These studies can also give useful information about pathways for metamorphism through pressure, temperature, space, and time.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How are analog models different than numerical models?


For some decades prior to the First Palestine Intifada in 1987, the Muslim Brotherhood in Palestine took a "quiescent" stance towards Israel, focusing on preaching, education and social services, and benefiting from Israel's "indulgence" to build up a network of mosques and charitable organizations. As the First Intifada gathered momentum and Palestinian shopkeepers closed their shops in support of the uprising, the Brotherhood announced the formation of HAMAS ("zeal"), devoted to Jihad against Israel. Rather than being more moderate than the PLO, the 1988 Hamas charter took a more uncompromising stand, calling for the destruction of Israel and the establishment of an Islamic state in Palestine. It was soon competing with and then overtaking the PLO for control of the intifada. The Brotherhood's base of devout middle class found common cause with the impoverished youth of the intifada in their cultural conservatism and antipathy for activities of the secular middle class such as drinking alcohol and going about without hijab.

Structural geologists use microscopic analysis of oriented thin sections of geologic samples to observe the fabric within the rocks which gives information about strain within the crystalline structure of the rocks. They also plot and combine measurements of geological structures in order to better understand the orientations of faults and folds in order to reconstruct the history of rock deformation in the area. In addition, they perform analog and numerical experiments of rock deformation in large and small settings.

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

Where does the jelly-like layer come from in complex animals?

According to the New York Times on July 22, 2014, the "richest 1 percent in the United States now own more wealth than the bottom 90 percent". Inherited wealth may help explain why many Americans who have become rich may have had a "substantial head start".

Steam engines are external combustion engines, where the working fluid is separate from the combustion products. Non-combustion heat sources such as solar power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In the cycle, water is heated and transforms into steam within a boiler operating at a high pressure. When expanded through pistons or turbines, mechanical work is done. The reduced-pressure steam is then condensed and pumped back into the boiler.

In the Rankine cycle, what does water turn into when heated?


The mayor of Warsaw is called President. Generally, in Poland, the mayors of bigger cities are called presidents – i.e. such cities, which have over 100,000 people or these, where already was president before 1990. The first Warsaw President was Jan Andrzej Menich (1695–1696). Between 1975 and 1990 the Warsaw Presidents was simultaneously the Warsaw Voivode. Since 1990 the President of Warsaw had been elected by the City council. In the years of 1994–1999 the mayor of the district Centrum automatically was designated as the President of Warsaw: the mayor of Centrum was elected by the district council of Centrum and the council was elected only by the Centrum residents. Since 2002 the President of Warsaw is elected by all of the citizens of Warsaw.

Read this: are prime for any natural number n. Here  represents the floor function, i.e., largest integer not greater than the number in question. The latter formula can be shown using Bertrand's postulate (proven first by Chebyshev), which states that there always exists at least one prime number p with n < p < 2n − 2, for any natural number n > 3. However, computing A or μ requires the knowledge of infinitely many primes to begin with. Another formula is based on Wilson's theorem and generates the number 2 many times and all other primes exactly once.

Compact trucks were introduced, such as the Toyota Hilux and the Datsun Truck, followed by the Mazda Truck (sold as the Ford Courier), and the Isuzu-built Chevrolet LUV. Mitsubishi rebranded its Forte as the Dodge D-50 a few years after the oil crisis. Mazda, Mitsubishi and Isuzu had joint partnerships with Ford, Chrysler, and GM, respectively. Later the American makers introduced their domestic replacements (Ford Ranger, Dodge Dakota and the Chevrolet S10/GMC S-15), ending their captive import policy.

Scottish Parliament:

Following a referendum in 1997, in which the Scottish electorate voted for devolution, the current Parliament was convened by the Scotland Act 1998, which sets out its powers as a devolved legislature. The Act delineates the legislative competence of the Parliament – the areas in which it can make laws – by explicitly specifying powers that are "reserved" to the Parliament of the United Kingdom. The Scottish Parliament has the power to legislate in all areas that are not explicitly reserved to Westminster. The British Parliament retains the ability to amend the terms of reference of the Scottish Parliament, and can extend or reduce the areas in which it can make laws. The first meeting of the new Parliament took place on 12 May 1999.

Historically, Victoria has been the base for the manufacturing plants of the major car brands Ford, Toyota and Holden; however, closure announcements by all three companies in the 21st century will mean that Australia will no longer be a base for the global car industry, with Toyota's statement in February 2014 outlining a closure year of 2017. Holden's announcement occurred in May 2013, followed by Ford's decision in December of the same year (Ford's Victorian plants—in Broadmeadows and Geelong—will close in October 2016).
Try to answer this question if possible (otherwise reply "unanswerable"): When did Holden announce that it will open its Victoria plant?


Read this: An increase in imported cars into North America forced General Motors, Ford and Chrysler to introduce smaller and fuel-efficient models for domestic sales. The Dodge Omni / Plymouth Horizon from Chrysler, the Ford Fiesta and the Chevrolet Chevette all had four-cylinder engines and room for at least four passengers by the late 1970s. By 1985, the average American vehicle moved 17.4 miles per gallon, compared to 13.5 in 1970. The improvements stayed even though the price of a barrel of oil remained constant at $12 from 1974 to 1979. Sales of large sedans for most makes (except Chrysler products) recovered within two model years of the 1973 crisis. The Cadillac DeVille and Fleetwood, Buick Electra, Oldsmobile 98, Lincoln Continental, Mercury Marquis, and various other luxury oriented sedans became popular again in the mid-1970s. The only full-size models that did not recover were lower price models such as the Chevrolet Bel Air, and Ford Galaxie 500. Slightly smaller, mid-size models such as the Oldsmobile Cutlass, Chevrolet Monte Carlo, Ford Thunderbird and various other models sold well.

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

 Who had military control during the Yuan?


Newborn infants have no prior exposure to microbes and are particularly vulnerable to infection. Several layers of passive protection are provided by the mother. During pregnancy, a particular type of antibody, called IgG, is transported from mother to baby directly across the placenta, so human babies have high levels of antibodies even at birth, with the same range of antigen specificities as their mother. Breast milk or colostrum also contains antibodies that are transferred to the gut of the infant and protect against bacterial infections until the newborn can synthesize its own antibodies. This is passive immunity because the fetus does not actually make any memory cells or antibodies—it only borrows them. This passive immunity is usually short-term, lasting from a few days up to several months. In medicine, protective passive immunity can also be transferred artificially from one individual to another via antibody-rich serum.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Newborns are vulnerable to infection because they have no previous exposure to what?


Read this: Ctenophores used to be regarded as "dead ends" in marine food chains because it was thought their low ratio of organic matter to salt and water made them a poor diet for other animals. It is also often difficult to identify the remains of ctenophores in the guts of possible predators, although the combs sometimes remain intact long enough to provide a clue. Detailed investigation of chum salmon, Oncorhynchus keta, showed that these fish digest ctenophores 20 times as fast as an equal weight of shrimps, and that ctenophores can provide a good diet if there are enough of them around. Beroids prey mainly on other ctenophores. Some jellyfish and turtles eat large quantities of ctenophores, and jellyfish may temporarily wipe out ctenophore populations. Since ctenophores and jellyfish often have large seasonal variations in population, most fish that prey on them are generalists, and may have a greater effect on populations than the specialist jelly-eaters. This is underlined by an observation of herbivorous fishes deliberately feeding on gelatinous zooplankton during blooms in the Red Sea. The larvae of some sea anemones are parasites on ctenophores, as are the larvae of some flatworms that parasitize fish when they reach adulthood.

The "freedom to provide services" under TFEU article 56 applies to people who give services "for remuneration", especially commercial or professional activity. For example, in Van Binsbergen v Bestuur van de Bedrijfvereniging voor de Metaalnijverheid a Dutch lawyer moved to Belgium while advising a client in a social security case, and was told he could not continue because Dutch law said only people established in the Netherlands could give legal advice. The Court of Justice held that the freedom to provide services applied, it was directly effective, and the rule was probably unjustified: having an address in the member state would be enough to pursue the legitimate aim of good administration of justice. The Court of Justice has held that secondary education falls outside the scope of article 56, because usually the state funds it, though higher education does not. Health care generally counts as a service. In Geraets-Smits v Stichting Ziekenfonds Mrs Geraets-Smits claimed she should be reimbursed by Dutch social insurance for costs of receiving treatment in Germany. The Dutch health authorities regarded the treatment unnecessary, so she argued this restricted the freedom (of the German health clinic) to provide services. Several governments submitted that hospital services should not be regarded as economic, and should not fall within article 56. But the Court of Justice held health was a "service" even though the government (rather than the service recipient) paid for the service. National authorities could be justified in refusing to reimburse patients for medical services abroad if the health care received at home was without undue delay, and it followed "international medical science" on which treatments counted as normal and necessary. The Court requires that the individual circumstances of a patient justify waiting lists, and this is also true in the context of the UK's National Health Service. Aside from public services, another sensitive field of services are those classified as illegal. Josemans v Burgemeester van Maastricht held that the Netherlands' regulation of cannabis consumption, including the prohibitions by some municipalities on tourists (but not Dutch nationals) going to coffee shops, fell outside article 56 altogether. The Court of Justice reasoned that narcotic drugs were controlled in all member states, and so this differed from other cases where prostitution or other quasi-legal activity was subject to restriction. If an activity does fall within article 56, a restriction can be justified under article 52 or overriding requirements developed by the Court of Justice. In Alpine Investments BV v Minister van Financiën a business that sold commodities futures (with Merrill Lynch and another banking firms) attempted to challenge a Dutch law that prohibiting cold calling customers. The Court of Justice held the Dutch prohibition pursued a legitimate aim to prevent "undesirable developments in securities trading" including protecting the consumer from aggressive sales tactics, thus maintaining confidence in the Dutch markets. In Omega Spielhallen GmbH v Bonn a "laserdrome" business was banned by the Bonn council. It bought fake laser gun services from a UK firm called Pulsar Ltd, but residents had protested against "playing at killing" entertainment. The Court of Justice held that the German constitutional value of human dignity, which underpinned the ban, did count as a justified restriction on freedom to provide services. In Liga Portuguesa de Futebol v Santa Casa da Misericórdia de Lisboa the Court of Justice also held that the state monopoly on gambling, and a penalty for a Gibraltar firm that had sold internet gambling services, was justified to prevent fraud and gambling where people's views were highly divergent. The ban was proportionate as this was an appropriate and necessary way to tackle the serious problems of fraud that arise over the internet. In the Services Directive a group of justifications were codified in article 16 that the case law has developed.

Why could a Dutch lawyer who moved to Belgium give legal advice?


Students at the University of Chicago run over 400 clubs and organizations known as Recognized Student Organizations (RSOs). These include cultural and religious groups, academic clubs and teams, and common-interest organizations. Notable extracurricular groups include the University of Chicago College Bowl Team, which has won 118 tournaments and 15 national championships, leading both categories internationally. The university's competitive Model United Nations team was the top ranked team in North America in 2013-14 and 2014-2015. Among notable RSOs are the nation's longest continuously running student film society Doc Films, organizing committee for the University of Chicago Scavenger Hunt, the twice-weekly student newspaper The Chicago Maroon, the alternative weekly student newspaper South Side Weekly, the nation's second oldest continuously running student improvisational theater troupe Off-Off Campus, and the university-owned radio station WHPK.

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


Read this: On 1 February 2007, the eve of the publication of IPCC's major report on climate, a study was published suggesting that temperatures and sea levels have been rising at or above the maximum rates proposed during the last IPCC report in 2001. The study compared IPCC 2001 projections on temperature and sea level change with observations. Over the six years studied, the actual temperature rise was near the top end of the range given by IPCC's 2001 projection, and the actual sea level rise was above the top of the range of the IPCC projection.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): How did the 2001 IPCC report compare to reality on temperature levels?


Read this: 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.

Packet switching:

In connectionless mode each packet includes complete addressing information. The packets are routed individually, sometimes resulting in different paths and out-of-order delivery. Each packet is labeled with a destination address, source address, and port numbers. It may also be labeled with the sequence number of the packet. This precludes the need for a dedicated path to help the packet find its way to its destination, but means that much more information is needed in the packet header, which is therefore larger, and this information needs to be looked up in power-hungry content-addressable memory. Each packet is dispatched and may go via different routes; potentially, the system has to do as much work for every packet as the connection-oriented system has to do in connection set-up, but with less information as to the application's requirements. At the destination, the original message/data is reassembled in the correct order, based on the packet sequence number. Thus a virtual connection, also known as a virtual circuit or byte stream is provided to the end-user by a transport layer protocol, although intermediate network nodes only provides a connectionless network layer service.

In the 1960s, a series of discoveries, the most important of which was seafloor spreading, showed that the Earth's lithosphere, which includes the crust and rigid uppermost portion of the upper mantle, is separated into a number of tectonic plates that move across the plastically deforming, solid, upper mantle, which is called the asthenosphere. There is an intimate coupling between the movement of the plates on the surface and the convection of the mantle: oceanic plate motions and mantle convection currents always move in the same direction, because the oceanic lithosphere is the rigid upper thermal boundary layer of the convecting mantle. This coupling between rigid plates moving on the surface of the Earth and the convecting mantle is called plate tectonics.

"The Islamic State", formerly known as the "Islamic State of Iraq and the Levant" and before that as the "Islamic State of Iraq", (and called the acronym Daesh by its many detractors), is a Wahhabi/Salafi jihadist extremist militant group which is led by and mainly composed of Sunni Arabs from Iraq and Syria. In 2014, the group proclaimed itself a caliphate, with religious, political and military authority over all Muslims worldwide. As of March 2015[update], it had control over territory occupied by ten million people in Iraq and Syria, and has nominal control over small areas of Libya, Nigeria and Afghanistan. (While a self-described state, it lacks international recognition.) The group also operates or has affiliates in other parts of the world, including North Africa and South Asia.

Homes from the early 20th century line this boulevard in the heart of the historic Alta Vista Tract. The section of Huntington Boulevard between First Street on the west to Cedar Avenue on the east is the home to many large, stately homes. The original development of this area began circa 1910, on 190 acres of what had been an alfalfa field. The Alta Vista Tract, as the land would become known, was mapped by William Stranahan for the Pacific Improvement Corporation, and was officially platted in 1911. The tract's boundaries were Balch Avenue on the south, Cedar Avenue on the east, the rear property line of Platt Avenue (east of Sixth Street) and Platt Avenue (west of Sixth Street) on the north, and First Street on the west. The subdivision was annexed to the City in January 1912, in an election that was the first in which women voted in the community. At the time of its admission to the City, the Alta Vista Tract was uninhabited but landscaped, although the trees had to be watered by tank wagon. In 1914 developers Billings & Meyering acquired the tract, completed street development, provided the last of the necessary municipal improvements including water service, and began marketing the property with fervor. A mere half decade later the tract had 267 homes. This rapid development was no doubt hastened by the Fresno Traction Company right-of-way along Huntington Boulevard, which provided streetcar connections between downtown and the County Hospital.

In what year did developers Billings & Meyering acquire the Alta Vista Tract?


Ctenophores form an animal phylum that is more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals). Unlike sponges, both ctenophores and cnidarians have: cells bound by inter-cell connections and carpet-like basement membranes; muscles; nervous systems; and some have sensory organs. Ctenophores are distinguished from all other animals by having colloblasts, which are sticky and adhere to prey, although a few ctenophore species lack them.

A job where there are many workers willing to work a large amount of time (high supply) competing for a job that few require (low demand) will result in a low wage for that job. This is because competition between workers drives down the wage. An example of this would be jobs such as dish-washing or customer service. Competition amongst workers tends to drive down wages due to the expendable nature of the worker in relation to his or her particular job. A job where there are few able or willing workers (low supply), but a large need for the positions (high demand), will result in high wages for that job. This is because competition between employers for employees will drive up the wage. Examples of this would include jobs that require highly developed skills, rare abilities, or a high level of risk. Competition amongst employers tends to drive up wages due to the nature of the job, since there is a relative shortage of workers for the particular position. Professional and labor organizations may limit the supply of workers which results in higher demand and greater incomes for members. Members may also receive higher wages through collective bargaining, political influence, or corruption.

Who works to get workers lower compensation?


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

Answer this question, if possible (if impossible, reply "unanswerable"): What animals does the Vistula river's ecosystem include?


Read this: 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.

For the next three hundred years, Scotland was directly governed by the Parliament of Great Britain and the subsequent Parliament of the United Kingdom, both seated at Westminster, and the lack of a Parliament of Scotland remained an important element in Scottish national identity. Suggestions for a 'devolved' Parliament were made before 1914, but were shelved due to the outbreak of the First World War. A sharp rise in nationalism in Scotland during the late 1960s fuelled demands for some form of home rule or complete independence, and in 1969 prompted the incumbent Labour government of Harold Wilson to set up the Kilbrandon Commission to consider the British constitution. One of the principal objectives of the commission was to examine ways of enabling more self-government for Scotland, within the unitary state of the United Kingdom. Kilbrandon published his report in 1973 recommending the establishment of a directly elected Scottish Assembly to legislate for the majority of domestic Scottish affairs.

In England, in the absence of census figures, historians propose a range of preincident population figures from as high as 7 million to as low as 4 million in 1300, and a postincident population figure as low as 2 million. By the end of 1350, the Black Death subsided, but it never really died out in England. Over the next few hundred years, further outbreaks occurred in 1361–62, 1369, 1379–83, 1389–93, and throughout the first half of the 15th century. An outbreak in 1471 took as much as 10–15% of the population, while the death rate of the plague of 1479–80 could have been as high as 20%. The most general outbreaks in Tudor and Stuart England seem to have begun in 1498, 1535, 1543, 1563, 1589, 1603, 1625, and 1636, and ended with the Great Plague of London in 1665.

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

Victoria has a written constitution enacted in 1975, but based on the 1855 colonial constitution, passed by the United Kingdom Parliament as the Victoria Constitution Act 1855, which establishes the Parliament as the state's law-making body for matters coming under state responsibility. The Victorian Constitution can be amended by the Parliament of Victoria, except for certain "entrenched" provisions that require either an absolute majority in both houses, a three-fifths majority in both houses, or the approval of the Victorian people in a referendum, depending on the provision.

Read this: However, this definition is disputed by Thoreau's political philosophy pitching the conscience vs. the collective. The individual is the final judge of right and wrong. More than this, since only individuals act, only individuals can act unjustly. When the government knocks on the door, it is an individual in the form of a postman or tax collector whose hand hits the wood. Before Thoreau’s imprisonment, when a confused taxman had wondered aloud about how to handle his refusal to pay, Thoreau had advised, “Resign.” If a man chose to be an agent of injustice, then Thoreau insisted on confronting him with the fact that he was making a choice. But if government is “the voice of the people,” as it is often called, shouldn’t that voice be heeded? Thoreau admits that government may express the will of the majority but it may also express nothing more than the will of elite politicians. Even a good form of government is “liable to be abused and perverted before the people can act through it.” Moreover, even if a government did express the voice of the people, this fact would not compel the obedience of individuals who disagree with what is being said. The majority may be powerful but it is not necessarily right. What, then, is the proper relationship between the individual and the government?

Force:

Tension forces can be modeled using ideal strings that are massless, frictionless, unbreakable, and unstretchable. They can be combined with ideal pulleys, which allow ideal strings to switch physical direction. Ideal strings transmit tension forces instantaneously in action-reaction pairs so that if two objects are connected by an ideal string, any force directed along the string by the first object is accompanied by a force directed along the string in the opposite direction by the second object. By connecting the same string multiple times to the same object through the use of a set-up that uses movable pulleys, the tension force on a load can be multiplied. For every string that acts on a load, another factor of the tension force in the string acts on the load. However, even though such machines allow for an increase in force, there is a corresponding increase in the length of string that must be displaced in order to move the load. These tandem effects result ultimately in the conservation of mechanical energy since the work done on the load is the same no matter how complicated the machine.

Read this: A regulation of the Rhine was called for, with an upper canal near Diepoldsau and a lower canal at Fußach, in order to counteract the constant flooding and strong sedimentation in the western Rhine Delta. The Dornbirner Ach had to be diverted, too, and it now flows parallel to the canalized Rhine into the lake. Its water has a darker color than the Rhine; the latter's lighter suspended load comes from higher up the mountains. It is expected that the continuous input of sediment into the lake will silt up the lake. This has already happened to the former Lake Tuggenersee.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What lake no longer has any silt?


Since its founding, the EU has operated among an increasing plurality of national and globalising legal systems. This has meant both the European Court of Justice and the highest national courts have had to develop principles to resolve conflicts of laws between different systems. Within the EU itself, the Court of Justice's view is that if EU law conflicts with a provision of national law, then EU law has primacy. In the first major case in 1964, Costa v ENEL, a Milanese lawyer, and former shareholder of an energy company, named Mr Costa refused to pay his electricity bill to Enel, as a protest against the nationalisation of the Italian energy corporations. He claimed the Italian nationalisation law conflicted with the Treaty of Rome, and requested a reference be made to both the Italian Constitutional Court and the Court of Justice under TFEU article 267. The Italian Constitutional Court gave an opinion that because the nationalisation law was from 1962, and the treaty was in force from 1958, Costa had no claim. By contrast, the Court of Justice held that ultimately the Treaty of Rome in no way prevented energy nationalisation, and in any case under the Treaty provisions only the Commission could have brought a claim, not Mr Costa. However, in principle, Mr Costa was entitled to plead that the Treaty conflicted with national law, and the court would have a duty to consider his claim to make a reference if there would be no appeal against its decision. The Court of Justice, repeating its view in Van Gend en Loos, said member states "albeit within limited spheres, have restricted their sovereign rights and created a body of law applicable both to their nationals and to themselves" on the "basis of reciprocity". EU law would not "be overridden by domestic legal provisions, however framed... without the legal basis of the community itself being called into question." This meant any "subsequent unilateral act" of the member state inapplicable. Similarly, in Amministrazione delle Finanze v Simmenthal SpA, a company, Simmenthal SpA, claimed that a public health inspection fee under an Italian law of 1970 for importing beef from France to Italy was contrary to two Regulations from 1964 and 1968. In "accordance with the principle of the precedence of Community law," said the Court of Justice, the "directly applicable measures of the institutions" (such as the Regulations in the case) "render automatically inapplicable any conflicting provision of current national law". This was necessary to prevent a "corresponding denial" of Treaty "obligations undertaken unconditionally and irrevocably by member states", that could "imperil the very foundations of the" EU. But despite the views of the Court of Justice, the national courts of member states have not accepted the same analysis.
What was the reason the Italian Constitutional court gave that resulted in Mr. Costa losing his his claim against ENEL? (If the question is unanswerable, say "unanswerable")

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

What forces are responsible for the interactions between atomic particles?


Federal safety standards, such as NHTSA Federal Motor Vehicle Safety Standard 215 (pertaining to safety bumpers), and compacts like the 1974 Mustang I were a prelude to the DOT "downsize" revision of vehicle categories. By 1977, GM's full-sized cars reflected the crisis. By 1979, virtually all "full-size" American cars had shrunk, featuring smaller engines and smaller outside dimensions. Chrysler ended production of their full-sized luxury sedans at the end of the 1981 model year, moving instead to a full front-wheel drive lineup for 1982 (except for the M-body Dodge Diplomat/Plymouth Gran Fury and Chrysler New Yorker Fifth Avenue sedans).
