History_of_science
In 1847, Hungarian physician Ignác Fülöp Semmelweis dramatically reduced the occurrency of puerperal fever by simply requiring physicians to wash their hands before attending to women in childbirth. This discovery predated the germ theory of disease. However, Semmelweis' findings were not appreciated by his contemporaries and came into use only with discoveries by British surgeon Joseph Lister, who in 1865 proved the principles of antisepsis. Lister's work was based on the important findings by French biologist Louis Pasteur. Pasteur was able to link microorganisms with disease, revolutionizing medicine. He also devised one of the most important methods in preventive medicine, when in 1880 he produced a vaccine against rabies. Pasteur invented the process of pasteurization, to help prevent the spread of disease through milk and other foods.

Portugal
Industry is diversified, ranging from automotive (Volkswagen Autoeuropa and Peugeot Citroen), aerospace (Embraer and OGMA), electronics and textiles, to food, chemicals, cement and wood pulp. Volkswagen Group's AutoEuropa motor vehicle assembly plant in Palmela is among the largest foreign direct investment projects in Portugal. Modern non-traditional technology-based industries, such as aerospace, biotechnology and information technology, have been developed in several locations across the country. Alverca, Covilhã, Évora, and Ponte de Sor are the main centres of the Portuguese aerospace industry, which is led by Brazil-based company Embraer and the Portuguese company OGMA. Following the turn of the 21st century, many major biotechnology and information technology industries have been founded, and are concentrated in the metropolitan areas of Lisbon, Porto, Braga, Coimbra and Aveiro.[citation needed]

Israel
The following day, the armies of four Arab countries—Egypt, Syria, Transjordan and Iraq—entered what had been British Mandatory Palestine, launching the 1948 Arab–Israeli War; Contingents from Yemen, Morocco, Saudi Arabia and Sudan joined the war. The apparent purpose of the invasion was to prevent the establishment of the Jewish state at inception, and some Arab leaders talked about driving the Jews into the sea. According to Benny Morris, Jews felt that the invading Arab armies aimed to slaughter the Jews. The Arab league stated that the invasion was to restore law and order and to prevent further bloodshed.

Diarrhea
According to two researchers, Nesse and Williams, diarrhea may function as an evolved expulsion defense mechanism. As a result, if it is stopped, there might be a delay in recovery. They cite in support of this argument research published in 1973 that found that treating Shigella with the anti-diarrhea drug (Co-phenotrope, Lomotil) caused people to stay feverish twice as long as those not so treated. The researchers indeed themselves observed that: "Lomotil may be contraindicated in shigellosis. Diarrhea may represent a defense mechanism".

A route through Beringia is seen as more likely than the Solutrean hypothesis. Kashani et al. 2012 state that "The similarities in ages and geographical distributions for C4c and the previously analyzed X2a lineage provide support to the scenario of a dual origin for Paleo-Indians. Taking into account that C4c is deeply rooted in the Asian portion of the mtDNA phylogeny and is indubitably of Asian origin, the finding that C4c and X2a are characterized by parallel genetic histories definitively dismisses the controversial hypothesis of an Atlantic glacial entry route into North America."

MP3
The compression works by reducing the accuracy of certain parts of a sound that are considered to be beyond the auditory resolution ability of most people. This method is commonly referred to as perceptual coding. It uses psychoacoustic models to discard or reduce precision of components less audible to human hearing, and then records the remaining information in an efficient manner.
These models ensure that the precision is reduced for the components that are what to human hearing?

51st_state
Other less likely contenders are Guam and the United States Virgin Islands, both of which are unincorporated organized territories of the United States. Also, the Northern Mariana Islands and American Samoa, an unorganized, unincorporated territory, could both attempt to gain statehood. Some proposals call for the Virgin Islands to be admitted with Puerto Rico as one state (often known as the proposed "Commonwealth of Prusvi", for Puerto Rico/U.S. Virgin Islands, or as "Puerto Virgo"), and for the amalgamation of U.S. territories or former territories in the Pacific Ocean, in the manner of the "Greater Hawaii" concept of the 1960s. Guam and the Northern Mariana Islands would be admitted as one state, along with Palau, the Federated States of Micronesia, and the Marshall Islands (although these latter three entities are now separate sovereign nations, which have Compact of Free Association relationships with the United States). Such a state would have a population of 412,381 (slightly lower than Wyoming's population) and a land area of 911.82 square miles (2,361.6 km2) (slightly smaller than Rhode Island). American Samoa could possibly be part of such a state, increasing the population to 467,900 and the area to 988.65 square miles (2,560.6 km2).

Immaculate_Conception
Contemporary Eastern Orthodox Christians often object to the dogmatic declaration of her immaculate conception as an "over-elaboration" of the faith and because they see it as too closely connected with a particular interpretation of the doctrine of ancestral sin. All the same, the historical and authentic tradition of Mariology in Byzantium took its historical point of departure from Sophronios, Damascene, and their imitators. The most famous Eastern Orthodox theologian to imply Mary's Immaculate Conception was St. Gregory Palamas. Though many passages from his works were long known to extol and attribute to Mary a Christlike holiness in her human nature, traditional objections to Palamas' disposition toward the Immaculate Conception typically rely on a poor understanding of his doctrine of "the purification of Mary" at the Annunciation. Not only did he explicitly cite St. Gregory Nazianzen for his understanding of Jesus' purification at His baptism and Mary's at the Annunciation, but Theophanes of Nicaea, Joseph Bryennius, and Gennadios Scholarios all explicitly placed Mary's Conception as the first moment of her all-immaculate participation in the divine energies to such a degree that she was always completely without spot and graced. In addition to Emperor Manuel II and Gennadius Scholarius, St. Mark of Ephesus also fervently defended Mary's title as "prepurified" against the Dominican, Manuel Calecas, who was perhaps promoting thomistic Mariology that denied Mary's all-holiness from the first moment of her existence.

Presbyterianism
Presbyterians distinguish themselves from other denominations by doctrine, institutional organization (or "church order") and worship; often using a "Book of Order" to regulate common practice and order. The origins of the Presbyterian churches are in Calvinism. Many branches of Presbyterianism are remnants of previous splits from larger groups. Some of the splits have been due to doctrinal controversy, while some have been caused by disagreement concerning the degree to which those ordained to church office should be required to agree with the Westminster Confession of Faith, which historically serves as an important confessional document – second only to the Bible, yet directing particularities in the standardization and translation of the Bible – in Presbyterian churches.

Qing_dynasty
In order not to let the routine administration take over the running of the empire, the Qing emperors made sure that all important matters were decided in the "Inner Court," which was dominated by the imperial family and Manchu nobility and which was located in the northern part of the Forbidden City. The core institution of the inner court was the Grand Council.[g] It emerged in the 1720s under the reign of the Yongzheng Emperor as a body charged with handling Qing military campaigns against the Mongols, but it soon took over other military and administrative duties and served to centralize authority under the crown. The Grand Councillors[h] served as a sort of privy council to the emperor.

Bird_migration
Birds fly at varying altitudes during migration. An expedition to Mt. Everest found skeletons of northern pintail Anas acuta and black-tailed godwit Limosa limosa at 5,000 m (16,000 ft) on the Khumbu Glacier. Bar-headed geese Anser indicus have been recorded by GPS flying at up to 6,540 metres (21,460 ft) while crossing the Himalayas, at the same time engaging in the highest rates of climb to altitude for any bird. Anecdotal reports of them flying much higher have yet to be corroborated with any direct evidence. Seabirds fly low over water but gain altitude when crossing land, and the reverse pattern is seen in landbirds. However most bird migration is in the range of 150 to 600 m (490 to 1,970 ft). Bird strike aviation records from the United States show most collisions occur below 600 m (2,000 ft) and almost none above 1,800 m (5,900 ft).

Atlantic_City,_New_Jersey
One by one, additional large hotels were constructed along the boardwalk, including the Brighton, Chelsea, Shelburne, Ambassador, Ritz Carlton, Mayflower, Madison House, and the Breakers. The Quaker-owned Chalfonte House, opened in 1868, and Haddon House, opened in 1869, flanked North Carolina Avenue at the beach end. Their original wood-frame structures would be enlarged, and even moved closer to the beach, over the years. The modern Chalfonte Hotel, eight stories tall, opened in 1904. The modern Haddon Hall was built in stages and was completed in 1929, at eleven stories. By this time, they were under the same ownership and merged into the Chalfonte-Haddon Hall Hotel, becoming the city's largest hotel with nearly 1,000 rooms. By 1930, the Claridge, the city's last large hotel before the casinos, opened its doors. The 400-room Claridge was built by a partnership that included renowned Philadelphia contractor John McShain. At 24 stories, it would become known as the "Skyscraper By The Sea." The city became known as the "The World's Playground.

Separation_of_church_and_state_in_the_United_States
Many early immigrant groups traveled to America to worship freely, particularly after the English Civil War and religious conflict in France and Germany. They included nonconformists like the Puritans, who were Protestant Christians fleeing religious persecution from the Anglican King of England. Despite a common background, the groups' views on religious toleration were mixed. While some such as Roger Williams of Rhode Island and William Penn of Pennsylvania ensured the protection of religious minorities within their colonies, others like the Plymouth Colony and Massachusetts Bay Colony had established churches. The Dutch colony of New Netherland established the Dutch Reformed Church and outlawed all other worship, though enforcement was sparse. Religious conformity was desired partly for financial reasons: the established Church was responsible for poverty relief, putting dissenting churches at a significant disadvantage.

New_Delhi
Much of New Delhi, planned by the leading 20th-century British architect Edwin Lutyens, was laid out to be the central administrative area of the city as a testament to Britain's imperial pretensions. New Delhi is structured around two central promenades called the Rajpath and the Janpath. The Rajpath, or King's Way, stretches from the Rashtrapati Bhavan to the India Gate. The Janpath (Hindi: "Path of the People"), formerly Queen's Way, begins at Connaught Circus and cuts the Rajpath at right angles. 19 foreign embassies are located on the nearby Shantipath (Hindi: "Path of Peace"), making it the largest diplomatic enclave in India.

Multiracial_American
In the early 19th century, the Indigenous American woman Sacagawea, who would help translate for and guide the Lewis and Clark Expedition in the West, married the French trapper Toussaint Charbonneau. Most marriages between Europeans and Indigenous Americans were between European men and Indigenous American women. Depending on the kinship system of the woman's tribe, their children would be more or less easily assimilated into the tribe. Nations that had matrilineal systems, such as the Creek and Cherokee in the Southeast, gave the mixed-race children status in their mother's clans and tribes. If the tribe had a patrilineal system, like the Omaha, the children of white fathers were considered white. Unless they were specifically adopted into the tribe by an adult male, they could have no social status in it.

Anti-aircraft_warfare
Unlike the heavier guns, these smaller weapons are in widespread use due to their low cost and ability to quickly follow the target. Classic examples of autocannons and large caliber guns are the 40 mm autocannon and the 8.8 cm FlaK 18, 36 gun, both designed by Bofors of Sweden. Artillery weapons of this sort have for the most part been superseded by the effective surface-to-air missile systems that were introduced in the 1950s, although they were still retained by many nations. The development of surface-to-air missiles began in Nazi Germany during the late World War II with missiles such as the Wasserfall, though no working system was deployed before the war's end, and represented new attempts to increase effectiveness of the anti-aircraft systems faced with growing threat from [bomber]s. Land-based SAMs can be deployed from fixed installations or mobile launchers, either wheeled or tracked. The tracked vehicles are usually armoured vehicles specifically designed to carry SAMs.

John,_King_of_England
John inherited a sophisticated system of administration in England, with a range of royal agents answering to the Royal Household: the Chancery kept written records and communications; the Treasury and the Exchequer dealt with income and expenditure respectively; and various judges were deployed to deliver justice around the kingdom. Thanks to the efforts of men like Hubert Walter, this trend towards improved record keeping continued into his reign. Like previous kings, John managed a peripatetic court that travelled around the kingdom, dealing with both local and national matters as he went. John was very active in the administration of England and was involved in every aspect of government. In part he was following in the tradition of Henry I and Henry II, but by the 13th century the volume of administrative work had greatly increased, which put much more pressure on a king who wished to rule in this style. John was in England for much longer periods than his predecessors, which made his rule more personal than that of previous kings, particularly in previously ignored areas such as the north.

In 2010, Boston was estimated to have 617,594 residents (a density of 12,200 persons/sq mile, or 4,700/km2) living in 272,481 housing units— a 5% population increase over 2000. The city is the third most densely populated large U.S. city of over half a million residents. Some 1.2 million persons may be within Boston's boundaries during work hours, and as many as 2 million during special events. This fluctuation of people is caused by hundreds of thousands of suburban residents who travel to the city for work, education, health care, and special events.

Eritrea
In 2010, a genetic study was conducted on the mummified remains of baboons that were brought back as gifts from Punt by the ancient Egyptians. Led by a research team from the Egyptian Museum and the University of California, the scientists used oxygen isotope analysis to examine hairs from two baboon mummies that had been preserved in the British Museum. One of the baboons had distorted isotopic data, so the other's oxygen isotope values were compared to those of present-day baboon specimens from regions of interest. The researchers found that the mummies most closely matched modern baboon specimens in Eritrea and Ethiopia, which they suggested implied that Punt was likely a narrow region that included eastern Ethiopia and all of Eritrea.

Samurai
Maintaining the household was the main duty of samurai women. This was especially crucial during early feudal Japan, when warrior husbands were often traveling abroad or engaged in clan battles. The wife, or okugatasama (meaning: one who remains in the home), was left to manage all household affairs, care for the children, and perhaps even defend the home forcibly. For this reason, many women of the samurai class were trained in wielding a polearm called a naginata or a special knife called the kaiken in an art called tantojutsu (lit. the skill of the knife), which they could use to protect their household, family, and honor if the need arose.

Race_(human_categorization)
Another way to look at differences between populations is to measure genetic differences rather than physical differences between groups. The mid-20th-century anthropologist William C. Boyd defined race as: "A population which differs significantly from other populations in regard to the frequency of one or more of the genes it possesses. It is an arbitrary matter which, and how many, gene loci we choose to consider as a significant 'constellation'". Leonard Lieberman and Rodney Kirk have pointed out that "the paramount weakness of this statement is that if one gene can distinguish races then the number of races is as numerous as the number of human couples reproducing." Moreover, the anthropologist Stephen Molnar has suggested that the discordance of clines inevitably results in a multiplication of races that renders the concept itself useless. The Human Genome Project states "People who have lived in the same geographic region for many generations may have some alleles in common, but no allele will be found in all members of one population and in no members of any other."

Idealism
Pluralistic idealism such as that of Gottfried Leibniz takes the view that there are many individual minds that together underlie the existence of the observed world and make possible the existence of the physical universe. Unlike absolute idealism, pluralistic idealism does not assume the existence of a single ultimate mental reality or "Absolute". Leibniz' form of idealism, known as Panpsychism, views "monads" as the true atoms of the universe and as entities having perception. The monads are "substantial forms of being",elemental, individual, subject to their own laws, non-interacting, each reflecting the entire universe. Monads are centers of force, which is substance while space, matter and motion are phenomenal and their form and existence is dependent on the simple and immaterial monads. There is a pre-established harmony established by God, the central monad, between the world in the minds of the monads and the external world of objects. Leibniz's cosmology embraced traditional Christian Theism. The English psychologist and philosopher James Ward inspired by Leibniz had also defended a form of pluralistic idealism. According to Ward the universe is composed of "psychic monads" of different levels, interacting for mutual self- betterment.

Classical_music
It is in this time that the notation of music on a staff and other elements of musical notation began to take shape. This invention made possible the separation of the composition of a piece of music from its transmission; without written music, transmission was oral, and subject to change every time it was transmitted. With a musical score, a work of music could be performed without the composer's presence. The invention of the movable-type printing press in the 15th century had far-reaching consequences on the preservation and transmission of music.

History_of_science
At the beginning of the 13th century, there were reasonably accurate Latin translations of the main works of almost all the intellectually crucial ancient authors, allowing a sound transfer of scientific ideas via both the universities and the monasteries. By then, the natural philosophy contained in these texts began to be extended by notable scholastics such as Robert Grosseteste, Roger Bacon, Albertus Magnus and Duns Scotus. Precursors of the modern scientific method, influenced by earlier contributions of the Islamic world, can be seen already in Grosseteste's emphasis on mathematics as a way to understand nature, and in the empirical approach admired by Bacon, particularly in his Opus Majus. Pierre Duhem's provocative thesis of the Catholic Church's Condemnation of 1277 led to the study of medieval science as a serious discipline, "but no one in the field any longer endorses his view that modern science started in 1277". However, many scholars agree with Duhem's view that the Middle Ages were a period of important scientific developments.

Tuvalu
The atolls have shown resilience to gradual sea-level rise, with atolls and reef islands being able to grow under current climate conditions by generating sufficient sand and coral debris that accumulates and gets dumped on the islands during cyclones. Gradual sea-level rise also allows for coral polyp activity to increase the reefs. However, if the increase in sea level occurs at faster rate as compared to coral growth, or if polyp activity is damaged by ocean acidification, then the resilience of the atolls and reef islands is less certain. The 2011 report of Pacific Climate Change Science Program of Australia concludes, in relation to Tuvalu, states the conclusions that over the course of the 21st century:

Association_football
A standard adult football match consists of two periods of 45 minutes each, known as halves. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called additional time in FIFA documents, but is most commonly referred to as stoppage time or injury time, while loss time can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. The referee alone signals the end of the match. In matches where a fourth official is appointed, toward the end of the half the referee signals how many minutes of stoppage time he intends to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa. Trailing 1–0 and with just two minutes remaining, Stoke were awarded a penalty. Villa's goalkeeper kicked the ball out of the ground, and by the time the ball had been recovered, the 90 minutes had elapsed and the game was over. The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed, thus no game shall end with a penalty to be taken.

Gene
Alleles at a locus may be dominant or recessive; dominant alleles give rise to their corresponding phenotypes when paired with any other allele for the same trait, whereas recessive alleles give rise to their corresponding phenotype only when paired with another copy of the same allele. For example, if the allele specifying tall stems in pea plants is dominant over the allele specifying short stems, then pea plants that inherit one tall allele from one parent and one short allele from the other parent will also have tall stems. Mendel's work demonstrated that alleles assort independently in the production of gametes, or germ cells, ensuring variation in the next generation. Although Mendelian inheritance remains a good model for many traits determined by single genes (including a number of well-known genetic disorders) it does not include the physical processes of DNA replication and cell division.
When do alleles assort independently?

However, asymmetry of causation can be observed in a non-arbitrary way which is not metaphysical in the case of a human hand dropping a cup of water which smashes into fragments on a hard floor, spilling the liquid. In this order, the causes of the resultant pattern of cup fragments and water spill is easily attributable in terms of the trajectory of the cup, irregularities in its structure, angle of its impact on the floor, etc. However, applying the same event in reverse, it is difficult to explain why the various pieces of the cup should fly up into the human hand and reassemble precisely into the shape of a cup, or why the water should position itself entirely within the cup. The causes of the resultant structure and shape of the cup and the encapsulation of the water by the hand within the cup are not easily attributable, as neither hand nor floor can achieve such formations of the cup or water. This asymmetry is perceivable on account of two features: i) the relationship between the agent capacities of the human hand (i.e., what it is and is not capable of and what it is for) and non-animal agency (i.e., what floors are and are not capable of and what they are for) and ii) that the pieces of cup came to possess exactly the nature and number of those of a cup before assembling. In short, such asymmetry is attributable to the relationship between temporal direction on the one hand and the implications of form and functional capacity on the other.
What else, besides direction, is asymmetry attributable to?

Emotion
Perspectives on emotions from evolutionary theory were initiated in the late 19th century with Charles Darwin's book The Expression of the Emotions in Man and Animals. Darwin argued that emotions actually served a purpose for humans, in communication and also in aiding their survival. Darwin, therefore, argued that emotions evolved via natural selection and therefore have universal cross-cultural counterparts. Darwin also detailed the virtues of experiencing emotions and the parallel experiences that occur in animals. This led the way for animal research on emotions and the eventual determination of the neural underpinnings of emotion.

Annelid
Earthworms are Oligochaetes that support terrestrial food chains both as prey and in some regions are important in aeration and enriching of soil. The burrowing of marine polychaetes, which may constitute up to a third of all species in near-shore environments, encourages the development of ecosystems by enabling water and oxygen to penetrate the sea floor. In addition to improving soil fertility, annelids serve humans as food and as bait. Scientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries. Ragworms' jaws are now being studied by engineers as they offer an exceptional combination of lightness and strength.

Multiracial_American
After the American Revolutionary War, the number and proportion of free people of color increased markedly in the North and the South as slaves were freed. Most northern states abolished slavery, sometimes, like New York, in programs of gradual emancipation that took more than two decades to be completed. The last slaves in New York were not freed until 1827. In connection with the Second Great Awakening, Quaker and Methodist preachers in the South urged slaveholders to free their slaves. Revolutionary ideals led many men to free their slaves, some by deed and others by will, so that from 1782 to 1810, the percentage of free people of color rose from less than one percent to nearly 10 percent of blacks in the South.

Tuvalu
The United Nations designates Tuvalu as a least developed country (LDC) because of its limited potential for economic development, absence of exploitable resources and its small size and vulnerability to external economic and environmental shocks. Tuvalu participates in the Enhanced Integrated Framework for Trade-Related Technical Assistance to Least Developed Countries (EIF), which was established in October 1997 under the auspices of the World Trade Organisation. In 2013 Tuvalu deferred its graduation from least developed country (LDC) status to a developing country to 2015. Prime Minister Enele Sopoaga said that this deferral was necessary to maintain access by Tuvalu to the funds provided by the United Nations's National Adaptation Programme of Action (NAPA), as "Once Tuvalu graduates to a developed country, it will not be considered for funding assistance for climate change adaptation programmes like NAPA, which only goes to LDCs". Tuvalu had met targets so that Tuvalu was to graduate from LDC status. Prime minister, Enele Sopoaga wants the United Nations to reconsider its criteria for graduation from LDC status as not enough weight is given to the environmental plight of small island states like Tuvalu in the application of the Environmental Vulnerability Index (EVI).

Under Walter Dill Scott's presidency from 1920 to 1939, Northwestern began construction of an integrated campus in Chicago designed by James Gamble Rogers to house the professional schools; established the Kellogg School of Management; and built several prominent buildings on the Evanston campus, Dyche Stadium (now named Ryan Field) and Deering Library among others. In 1933, a proposal to merge Northwestern with the University of Chicago was considered but rejected. Northwestern was also one of the first six universities in the country to establish a Naval Reserve Officers Training Corps (NROTC) in the 1920s. Northwestern played host to the first-ever NCAA Men's Division I Basketball Championship game in 1939 in the original Patten Gymnasium, which was later demolished and relocated farther north along with the Dearborn Observatory to make room for the Technological Institute.

The American people are mostly multi-ethnic descendants of various culturally distinct immigrant groups, many of which have now developed nations. Some consider themselves multiracial, while acknowledging race as a social construct. Creolization, assimilation and integration have been continuing processes. The African-American Civil Rights Movement (1955–1968) and other social movements since the mid-twentieth century worked to achieve social justice and equal enforcement of civil rights under the constitution for all ethnicities. In the 2000s, less than 5% of the population identified as multiracial. In many instances, mixed racial ancestry is so far back in an individual's family history (for instance, before the Civil War or earlier), that it does not affect more recent ethnic and cultural identification.

Athanasius_of_Alexandria
Athanasius's episcopate began on 9 May 328 as the Alexandrian Council elected Athanasius to succeed the aged Alexander. That council also denounced various heresies and schisms, many of which continued to preoccupy his 45-year-long episcopate (c. 8 June 328 – 2 May 373). Patriarch Athanasius spent over 17 years in five exiles ordered by four different Roman Emperors, not counting approximately six more incidents in which Athanasius fled Alexandria to escape people seeking to take his life. This gave rise to the expression "Athanasius contra mundum" or "Athanasius against the world". However, during his first years as bishop, Athanasius visited the churches of his territory, which at that time included all of Egypt and Libya. He established contacts with the hermits and monks of the desert, including Pachomius, which proved very valuable to him over the years. Shortly thereafter, Athanasius became occupied with the theological disputes against Arians within the Byzantine Empire that would occupy much of his life.

History_of_India
The Nawab of Bengal Siraj Ud Daulah, the de facto ruler of the Bengal province, opposed British attempts to use these permits. This led to the Battle of Plassey on 23 June 1757, in which the Bengal Army of the East India Company, led by Robert Clive, defeated the French-supported Nawab's forces. This was the first real political foothold with territorial implications that the British acquired in India. Clive was appointed by the company as its first 'Governor of Bengal' in 1757. This was combined with British victories over the French at Madras, Wandiwash and Pondichéry that, along with wider British successes during the Seven Years' War, reduced French influence in India. The British East India Company extended its control over the whole of Bengal. After the Battle of Buxar in 1764, the company acquired the rights of administration in Bengal from de jure Mughal Emperor Shah Alam II; this marked the beginning of its formal rule, which within the next century engulfed most of India. The East India Company monopolized the trade of Bengal. They introduced a land taxation system called the Permanent Settlement which introduced a feudal-like structure in Bengal, often with zamindars set in place.

Axons transmit signals to other neurons by means of specialized junctions called synapses. A single axon may make as many as several thousand synaptic connections with other cells. When an action potential, traveling along an axon, arrives at a synapse, it causes a chemical called a neurotransmitter to be released. The neurotransmitter binds to receptor molecules in the membrane of the target cell.

Beside the introduction of the lute to Spain (Andalusia) by the Moors, another important point of transfer of the lute from Arabian to European culture was Sicily, where it was brought either by Byzantine or later by Muslim musicians. There were singer-lutenists at the court in Palermo following the Norman conquest of the island from the Muslims, and the lute is depicted extensively in the ceiling paintings in the Palermo’s royal Cappella Palatina, dedicated by the Norman King Roger II of Sicily in 1140. His Hohenstaufen grandson Frederick II, Holy Roman Emperor (1194 - 1250) continued integrating Muslims into his court, including Moorish musicians. By the 14th century, lutes had disseminated throughout Italy and, probably because of the cultural influence of the Hohenstaufen kings and emperor, based in Palermo, the lute had also made significant inroads into the German-speaking lands.

There is also a high concentration of I2a2a in the Moldavian region of Romania, Moldova and western Ukraine. According to original studies, Hg I2a2 was believed to have arisen in the west Balkans sometime after the LGM, subsequently spreading from the Balkans through Central Russian Plain. Recently, Ken Nordtvedt has split I2a2 into two clades – N (northern) and S (southern), in relation where they arose compared to Danube river. He proposes that N is slightly older than S. He recalculated the age of I2a2 to be ~ 2550 years and proposed that the current distribution is explained by a Slavic expansion from the area north-east of the Carpathians.

In North America, especially the first half of this period, people experienced considerable prosperity in the Roaring Twenties. The social and societal upheaval known as the Roaring Twenties began in North America and spread to Europe in the aftermath of World War I. The Roaring Twenties, often called "The Jazz Age", saw an exposition of social, artistic, and cultural dynamism. 'Normalcy' returned to politics, jazz music blossomed, the flapper redefined modern womanhood, Art Deco peaked. The spirit of the Roaring Twenties was marked by a general feeling of discontinuity associated with modernity, a break with traditions. Everything seemed to be feasible through modern technology. New technologies, especially automobiles, movies and radio proliferated 'modernity' to a large part of the population. The 1920s saw the general favor of practicality, in architecture as well as in daily life.

MIs are less commonly caused by coronary artery spasms, which may be due to cocaine, significant emotional stress, and extreme cold, among others. A number of tests are useful to help with diagnosis, including electrocardiograms (ECGs), blood tests, and coronary angiography. An ECG may confirm an ST elevation MI if ST elevation is present. Commonly used blood tests include troponin and less often creatine kinase MB.

Insect
Other developmental and reproductive variations include haplodiploidy, polymorphism, paedomorphosis or peramorphosis, sexual dimorphism, parthenogenesis and more rarely hermaphroditism.:143 In haplodiploidy, which is a type of sex-determination system, the offspring's sex is determined by the number of sets of chromosomes an individual receives. This system is typical in bees and wasps. Polymorphism is where a species may have different morphs or forms, as in the oblong winged katydid, which has four different varieties: green, pink and yellow or tan. Some insects may retain phenotypes that are normally only seen in juveniles; this is called paedomorphosis. In peramorphosis, an opposite sort of phenomenon, insects take on previously unseen traits after they have matured into adults. Many insects display sexual dimorphism, in which males and females have notably different appearances, such as the moth Orgyia recens as an exemplar of sexual dimorphism in insects.

Mammal
Mammalian hair, also known as pelage, can vary in color between populations, organisms within a population, and even on the individual organism. Light-dark color variation is common in the mammalian taxa. Sometimes, this color variation is determined by age variation, however, in other cases, it is determined by other factors. Selective pressures, such as ecological interactions with other populations or environmental conditions, often lead to the variation in mammalian coloration. These selective pressures favor certain colors in order to increase survival. Camouflage is thought to be a major selection pressure shaping coloration in mammals, although there is also evidence that sexual selection, communication, and physiological processes may influence the evolution of coloration as well. Camouflage is the most predominant mechanism for color variation, as it aids in the concealment of the organisms from predators or from their prey. Coat color can also be for intraspecies communication such as warning members of their species about predators, indicating health for reproductive purposes, communicating between mother and young, and intimidating predators. Studies have shown that in some cases, differences in female and male coat color could indicate information nutrition and hormone levels, which are important in the mate selection process. One final mechanism for coat color variation is physiological response purposes, such as temperature regulation in tropical or arctic environments. Although much has been observed about color variation, much of the genetic that link coat color to genes is still unknown. The genetic sites where pigmentation genes are found are known to affect phenotype by: 1) altering the spatial distribution of pigmentation of the hairs, and 2) altering the density and distribution of the hairs. Quantitative trait mapping is being used to better understand the distribution of loci responsible for pigmentation variation. However, although the genetic sites are known, there is still much to learn about how these genes are expressed.

Digestion
After some time (typically 1–2 hours in humans, 4–6 hours in dogs, 3–4 hours in house cats),[citation needed] the resulting thick liquid is called chyme. When the pyloric sphincter valve opens, chyme enters the duodenum where it mixes with digestive enzymes from the pancreas and bile juice from the liver and then passes through the small intestine, in which digestion continues. When the chyme is fully digested, it is absorbed into the blood. 95% of absorption of nutrients occurs in the small intestine. Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic about 5.6 ~ 6.9. Some vitamins, such as biotin and vitamin K (K2MK7) produced by bacteria in the colon are also absorbed into the blood in the colon. Waste material is eliminated from the rectum during defecation.

It also used to be commonplace to have a team play an exhibition against Minor League affiliates during the regular season, but worries of injuries to players, along with travel issues, have made this very rare. Exhibitions between inter-city teams in different leagues, like Chicago's Crosstown Classic and New York's Subway Series which used to be played solely as exhibitions for bragging rights are now blended into interleague play. The annual MLB All-Star Game, played in July between players from AL teams and players from NL teams, was long considered an exhibition match, but as of 2003 this status was questioned because the league whose team wins the All-Star game has been awarded home field advantage for the upcoming World Series.

Utrecht
Utrecht is the centre of a densely populated area, which makes concise definitions of its agglomeration difficult, and somewhat arbitrary. The smaller Utrecht agglomeration of continuously built up areas counts some 420,000 inhabitants and includes Nieuwegein, IJsselstein and Maarssen. It is sometimes argued that the close by municipalities De Bilt, Zeist, Houten, Vianen, Driebergen-Rijsenburg (Utrechtse Heuvelrug), and Bunnik should also be counted towards the Utrecht agglomeration, bringing the total to 640,000 inhabitants. The larger region, including slightly more remote towns such as Woerden and Amersfoort counts up to 820,000 inhabitants.

Aircraft_carrier
Since the early 1950s on conventional carriers it has been the practice to recover aircraft at an angle to port of the axial line of the ship. The primary function of this angled deck is to allow aircraft that miss the arresting wires, referred to as a bolter, to become airborne again without the risk of hitting aircraft parked forward. The angled deck allows the installation of one or two "waist" catapults in addition to the two bow cats. An angled deck also improves launch and recovery cycle flexibility with the option of simultaneous launching and recovery of aircraft.

Pope_Paul_VI
In 1976 Montini became the first pontiff in modern history to deny the accusation of homosexuality. Published by his order in January 1976 was a homily Persona Humana: Declaration on Certain Questions concerning Sexual Ethics, which outlawed pre or extra-marital sex, condemned homosexuality, and forbade masturbation. It provoked French author and former diplomat Roger Peyrefitte, in an interview published by the magazine Tempo, to accuse Montini of hypocrisy, and of having a longtime lover who was a movie actor. According to rumors prevalent both inside the Curia and in Italian society, this was Paolo Carlini, who had a bit part as a hairdresser in the Audrey Hepburn film Roman Holiday. Peyrefitte had previously published the accusation in two books, but the interview (previously published in a French gay magazine) brought the rumors to a wider public and caused an uproar. In a brief address to a crowd of approximately 20,000 in St. Peters Square on April 18, Montini called the charges "horrible and slanderous insinuations" and appealed for prayers on his behalf. Special prayers for Montini were said in all Italian Roman Catholic churches in "a day of consolation". In 1984 a New York Times correspondent repeated the allegations.

Gene
The majority of eukaryotic genes are stored on a set of large, linear chromosomes. The chromosomes are packed within the nucleus in complex with storage proteins called histones to form a unit called a nucleosome. DNA packaged and condensed in this way is called chromatin.:4.2 The manner in which DNA is stored on the histones, as well as chemical modifications of the histone itself, regulate whether a particular region of DNA is accessible for gene expression. In addition to genes, eukaryotic chromosomes contain sequences involved in ensuring that the DNA is copied without degradation of end regions and sorted into daughter cells during cell division: replication origins, telomeres and the centromere.:4.2 Replication origins are the sequence regions where DNA replication is initiated to make two copies of the chromosome. Telomeres are long stretches of repetitive sequence that cap the ends of the linear chromosomes and prevent degradation of coding and regulatory regions during DNA replication. The length of the telomeres decreases each time the genome is replicated and has been implicated in the aging process. The centromere is required for binding spindle fibres to separate sister chromatids into daughter cells during cell division.:18.2

2008_Sichuan_earthquake
Initially, officials were unable to contact the Wolong National Nature Reserve, home to around 280 giant pandas. However, the Foreign Ministry later said that a group of 31 British tourists visiting the Wolong Panda Reserve in the quake-hit area returned safe and uninjured to Chengdu. Nonetheless, the well-being of an even greater number of pandas in the neighbouring panda reserves remained unknown. Five security guards at the reserve were killed by the earthquake. Six pandas escaped after their enclosures were damaged. By May 20, two pandas at the reserve were found to be injured, while the search continued for another two adult pandas that went missing after the quake. By May 28, 2008, one panda was still missing. The missing panda was later found dead under the rubble of an enclosure. Nine-year-old Mao Mao, a mother of five at the breeding center, was discovered on Monday, her body crushed by a wall in her enclosure.

Premier_League
As of the 2015–16 season, Premier League football has been played in 53 stadiums since the formation of the Premier League in 1992. The Hillsborough disaster in 1989 and the subsequent Taylor Report saw a recommendation that standing terraces should be abolished; as a result all stadiums in the Premier League are all-seater. Since the formation of the Premier League, football grounds in England have seen constant improvements to capacity and facilities, with some clubs moving to new-build stadiums. Nine stadiums that have seen Premier League football have now been demolished. The stadiums for the 2010–11 season show a large disparity in capacity: Old Trafford, the home of Manchester United has a capacity of 75,957 with Bloomfield Road, the home of Blackpool, having a capacity of 16,220.

Seven_Years%27_War
The war was successful for Great Britain, which gained the bulk of New France in North America, Spanish Florida, some individual Caribbean islands in the West Indies, the colony of Senegal on the West African coast, and superiority over the French trading outposts on the Indian subcontinent. The Native American tribes were excluded from the settlement; a subsequent conflict, known as Pontiac's War, was also unsuccessful in returning them to their pre-war status. In Europe, the war began disastrously for Prussia, but a combination of good luck and successful strategy saw King Frederick the Great manage to retrieve the Prussian position and retain the status quo ante bellum. Prussia emerged as a new European great power. Although Austria failed to retrieve the territory of Silesia from Prussia (its original goal) its military prowess was also noted by the other powers. The involvement of Portugal, Spain and Sweden did not return them to their former status as great powers. France was deprived of many of its colonies and had saddled itself with heavy war debts that its inefficient financial system could barely handle. Spain lost Florida but gained French Louisiana and regained control of its colonies, e.g., Cuba and the Philippines, which had been captured by the British during the war. France and other European powers avenged their defeat in 1778 when the American Revolutionary War broke out, with hopes of destroying Britain's dominance once and for all.

When paying a state visit to Britain, foreign heads of state are usually entertained by the Queen at Buckingham Palace. They are allocated a large suite of rooms known as the Belgian Suite, situated at the foot of the Minister's Staircase, on the ground floor of the north-facing Garden Wing. The rooms of the suite are linked by narrow corridors, one of them is given extra height and perspective by saucer domes designed by Nash in the style of Soane. A second corridor in the suite has Gothic influenced cross over vaulting. The Belgian Rooms themselves were decorated in their present style and named after Prince Albert's uncle Léopold I, first King of the Belgians.

Franco-Prussian_War
The causes of the Franco-Prussian War are deeply rooted in the events surrounding the unification of Germany. In the aftermath of the Austro–Prussian War of 1866, Prussia had annexed numerous territories and formed the North German Confederation. This new power destabilized the European balance of power established by the Congress of Vienna in 1815 after the Napoleonic Wars. Napoleon III, then the emperor of France, demanded compensations in Belgium and on the left bank of the Rhine to secure France's strategic position, which the Prussian chancellor, Otto von Bismarck, flatly refused. Prussia then turned its attention towards the south of Germany, where it sought to incorporate the southern German kingdoms, Bavaria, Württemberg, Baden and Hesse-Darmstadt, into a unified Prussia-dominated Germany. France was strongly opposed to any further alliance of German states, which would have significantly strengthened the Prussian military.

Strasbourg
The tram system that now criss-crosses the historic city centre complements walking and biking in it. The centre has been transformed into a pedestrian priority zone that enables and invites walking and biking by making these active modes of transport comfortable, safe and enjoyable. These attributes are accomplished by applying the principle of "filtered permeability" to the existing irregular network of streets. It means that the network adaptations favour active transportation and, selectively, "filter out" the car by reducing the number of streets that run through the centre. While certain streets are discontinuous for cars, they connect to a network of pedestrian and bike paths which permeate the entire centre. In addition, these paths go through public squares and open spaces increasing the enjoyment of the trip. This logic of filtering a mode of transport is fully expressed in a comprehensive model for laying out neighbourhoods and districts – the Fused Grid.

History_of_science
The basis for classical economics forms Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. Smith criticized mercantilism, advocating a system of free trade with division of labour. He postulated an "invisible hand" that regulated economic systems made up of actors guided only by self-interest. Karl Marx developed an alternative economic theory, called Marxian economics. Marxian economics is based on the labor theory of value and assumes the value of good to be based on the amount of labor required to produce it. Under this assumption, capitalism was based on employers not paying the full value of workers labor to create profit. The Austrian school responded to Marxian economics by viewing entrepreneurship as driving force of economic development. This replaced the labor theory of value by a system of supply and demand.

Copper
Copper-alloy touch surfaces have natural intrinsic properties to destroy a wide range of microorganisms (e.g., E. coli O157:H7, methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus, Clostridium difficile, influenza A virus, adenovirus, and fungi). Some 355 copper alloys were proven to kill more than 99.9% of disease-causing bacteria within just two hours when cleaned regularly. The United States Environmental Protection Agency (EPA) has approved the registrations of these copper alloys as "antimicrobial materials with public health benefits," which allows manufacturers to legally make claims as to the positive public health benefits of products made with registered antimicrobial copper alloys. In addition, the EPA has approved a long list of antimicrobial copper products made from these alloys, such as bedrails, handrails, over-bed tables, sinks, faucets, door knobs, toilet hardware, computer keyboards, health club equipment, shopping cart handles, etc. (for a comprehensive list of products, see: Antimicrobial copper-alloy touch surfaces#Approved products). Copper doorknobs are used by hospitals to reduce the transfer of disease, and Legionnaires' disease is suppressed by copper tubing in plumbing systems. Antimicrobial copper alloy products are now being installed in healthcare facilities in the U.K., Ireland, Japan, Korea, France, Denmark, and Brazil[citation needed] and in the subway transit system in Santiago, Chile, where copper-zinc alloy handrails will be installed in some 30 stations between 2011–2014.

Probably the most influential single device on the interpretation of these characters was the Teletype Model 33 ASR, which was a printing terminal with an available paper tape reader/punch option. Paper tape was a very popular medium for long-term program storage until the 1980s, less costly and in some ways less fragile than magnetic tape. In particular, the Teletype Model 33 machine assignments for codes 17 (Control-Q, DC1, also known as XON), 19 (Control-S, DC3, also known as XOFF), and 127 (Delete) became de facto standards. The Model 33 was also notable for taking the description of Control-G (BEL, meaning audibly alert the operator) literally as the unit contained an actual bell which it rang when it received a BEL character. Because the keytop for the O key also showed a left-arrow symbol (from ASCII-1963, which had this character instead of underscore), a noncompliant use of code 15 (Control-O, Shift In) interpreted as "delete previous character" was also adopted by many early timesharing systems but eventually became neglected.

Circadian_rhythm
The central oscillator generates a self-sustaining rhythm and is driven by two interacting feedback loops that are active at different times of day. The morning loop consists of CCA1 (Circadian and Clock-Associated 1) and LHY (Late Elongated Hypocotyl), which encode closely related MYB transcription factors that regulate circadian rhythms in Arabidopsis, as well as PRR 7 and 9 (Pseudo-Response Regulators.) The evening loop consists of GI (Gigantea) and ELF4, both involved in regulation of flowering time genes. When CCA1 and LHY are overexpressed (under constant light or dark conditions), plants become arrhythmic, and mRNA signals reduce, contributing to a negative feedback loop. Gene expression of CCA1 and LHY oscillates and peaks in the early morning, whereas TOC1 gene expression oscillates and peaks in the early evening. While it was previously hypothesised that these three genes model a negative feedback loop in which over-expressed CCA1 and LHY repress TOC1 and over-expressed TOC1 is a positive regulator of CCA1 and LHY, it was shown in 2012 by Andrew Millar and others that TOC1 in fact serves as a repressor not only of CCA1, LHY, and PRR7 and 9 in the morning loop but also of GI and ELF4 in the evening loop. This finding and further computational modeling of TOC1 gene functions and interactions suggest a reframing of the plant circadian clock as a triple negative-component repressilator model rather than the positive/negative-element feedback loop characterizing the clock in mammals.

Wellington was at Eton from 1781 to 1784 and was to send his sons there. According to Nevill (citing the historian Sir Edward Creasy), what Wellington said, while passing an Eton cricket match many decades later, was, "There grows the stuff that won Waterloo", a remark Nevill construes as a reference to "the manly character induced by games and sport" amongst English youth generally, not a comment about Eton specifically. In 1889, Sir William Fraser conflated this uncorroborated remark with the one attributed to him by Count Charles de Montalembert's "C'est ici qu'a été gagné la bataille de Waterloo" ("It is here that the Battle of Waterloo was won.")

Muammar_Gaddafi
The son of an impoverished Bedouin goat herder, Gaddafi became involved in politics while at school in Sabha, subsequently enrolling in the Royal Military Academy, Benghazi. Founding a revolutionary cell within the military, in 1969 they seized power from the absolute monarchy of King Idris in a bloodless coup. Becoming Chairman of the governing Revolutionary Command Council (RCC), Gaddafi abolished the monarchy and proclaimed the Republic. Ruling by decree, he implemented measures to remove what he viewed as foreign imperialist influence from Libya, and strengthened ties to Arab nationalist governments. Intent on pushing Libya towards "Islamic socialism", he introduced sharia as the basis for the legal system and nationalized the oil industry, using the increased revenues to bolster the military, implement social programs and fund revolutionary militants across the world. In 1973 he initiated a "Popular Revolution" with the formation of General People's Committees (GPCs), purported to be a system of direct democracy, but retained personal control over major decisions. He outlined his Third International Theory that year, publishing these ideas in The Green Book.
