The pointed arch, one of the defining attributes of Gothic, was earlier incorporated into Islamic architecture following the Islamic conquests of Roman Syria and the Sassanid Empire in the Seventh Century. The pointed arch and its precursors had been employed in Late Roman and Sassanian architecture; within the Roman context, evidenced in early church building in Syria and occasional secular structures, like the Roman Karamagara Bridge; in Sassanid architecture, in the parabolic and pointed arches employed in palace and sacred construction.

Popper won many awards and honours in his field, including the Lippincott Award of the American Political Science Association, the Sonning Prize, the Otto Hahn Peace Medal of the United Nations Association of Germany in Berlin and fellowships in the Royal Society, British Academy, London School of Economics, King's College London, Darwin College, Cambridge, and Charles University, Prague. Austria awarded him the Grand Decoration of Honour in Gold for Services to the Republic of Austria in 1986, and the Federal Republic of Germany its Grand Cross with Star and Sash of the Order of Merit, and the peace class of the Order Pour le Mérite. He received the Humanist Laureate Award from the International Academy of Humanism. He was knighted by Queen Elizabeth II in 1965, and was elected a Fellow of the Royal Society in 1976. He was invested with the Insignia of a Companion of Honour in 1982.

Two common considerations have the Latin names lectio brevior (shorter reading) and lectio difficilior (more difficult reading). The first is the general observation that scribes tended to add words, for clarification or out of habit, more often than they removed them. The second, lectio difficilior potior (the harder reading is stronger), recognizes the tendency for harmonization—resolving apparent inconsistencies in the text. Applying this principle leads to taking the more difficult (unharmonized) reading as being more likely to be the original. Such cases also include scribes simplifying and smoothing texts they did not fully understand.

Between 1836 and 1842 Victorian Aboriginal groups were largely dispossessed[by whom?] of their land. By January 1844, there were said to be 675 Aborigines resident in squalid camps in Melbourne. The British Colonial Office appointed five Aboriginal Protectors for the Aborigines of Victoria, in 1839, however their work was nullified by a land policy that favoured squatters to take possession of Aboriginal lands. By 1845, fewer than 240 wealthy Europeans held all the pastoral licences then issued in Victoria and became a powerful political and economic force in Victoria for generations to come.

Polabian Slavs (Wends) settled in parts of England (Danelaw), apparently as Danish allies. Polabian-Pomeranian Slavs are also known to have even settled on Norse age Iceland. Saqaliba refers to the Slavic mercenaries and slaves in the medieval Arab world in North Africa, Sicily and Al-Andalus. Saqaliba served as caliph's guards. In the 12th century, there was intensification of Slavic piracy in the Baltics. The Wendish Crusade was started against the Polabian Slavs in 1147, as a part of the Northern Crusades. Niklot, pagan chief of the Slavic Obodrites, began his open resistance when Lothar III, Holy Roman Emperor, invaded Slavic lands. In August 1160 Niklot was killed and German colonization (Ostsiedlung) of the Elbe-Oder region began. In Hanoverian Wendland, Mecklenburg-Vorpommern and Lusatia invaders started germanization. Early forms of germanization were described by German monks: Helmold in the manuscript Chronicon Slavorum and Adam of Bremen in Gesta Hammaburgensis ecclesiae pontificum. The Polabian language survived until the beginning of the 19th century in what is now the German state of Lower Saxony. In Eastern Germany, around 20% of Germans have Slavic paternal ancestry. Similarly, in Germany, around 20% of the foreign surnames are of Slavic origin.

The earliest archaeological artifacts in Iran, like those excavated at the Kashafrud and Ganj Par sites, attest to a human presence in Iran since the Lower Paleolithic era, c. 800,000–200,000 BC. Iran's Neanderthal artifacts from the Middle Paleolithic period, c. 200,000–40,000 BC, have been found mainly in the Zagros region, at sites such as Warwasi and Yafteh Cave.[page needed] Around 10th to 8th millennium BC, early agricultural communities such as Chogha Golan and Chogha Bonut began to flourish in Iran, as well as Susa and Chogha Mish developing in and around the Zagros region.[page needed]

Northwestern's football team has made 73 appearances in the top 10 of the AP poll since 1936 (including 5 at #1) and has won eight Big Ten conference championships since 1903. At one time, Northwestern had the longest losing streak in Division I-A, losing 34 consecutive games between 1979 and 1982. They did not appear in a bowl game after 1949 until the 1996 Rose Bowl. The team did not win a bowl since the 1949 Rose Bowl until the 2013 Gator Bowl. Following the sudden death of football coach Randy Walker in 2006, 31-year-old former All-American Northwestern linebacker Pat Fitzgerald assumed the position, becoming the youngest Division I FBS coach at the time.

In the United States, August Vollmer introduced other reforms, including education requirements for police officers. O.W. Wilson, a student of Vollmer, helped reduce corruption and introduce professionalism in Wichita, Kansas, and later in the Chicago Police Department. Strategies employed by O.W. Wilson included rotating officers from community to community to reduce their vulnerability to corruption, establishing of a non-partisan police board to help govern the police force, a strict merit system for promotions within the department, and an aggressive recruiting drive with higher police salaries to attract professionally qualified officers. During the professionalism era of policing, law enforcement agencies concentrated on dealing with felonies and other serious crime, rather than broader focus on crime prevention.

A new phase in neoclassical design was inaugurated by Robert and James Adam, who travelled in Italy and Dalmatia in the 1750s, observing the ruins of the classical world. On their return to Britain, they published a book entitled The Works in Architecture in installments between 1773 and 1779. This book of engraved designs made the Adam repertory available throughout Europe. The Adam brothers aimed to simplify the rococo and baroque styles which had been fashionable in the preceding decades, to bring what they felt to be a lighter and more elegant feel to Georgian houses. The Works in Architecture illustrated the main buildings the Adam brothers had worked on and crucially documented the interiors, furniture and fittings, designed by the Adams.

During the summer growing season, phosphate is at a high level. It has a vital role in the breakdown of the sugars manufactured by chlorophyll. But in the fall, phosphate, along with the other chemicals and nutrients, moves out of the leaf into the stem of the plant. When this happens, the sugar-breakdown process changes, leading to the production of anthocyanin pigments. The brighter the light during this period, the greater the production of anthocyanins and the more brilliant the resulting color display. When the days of autumn are bright and cool, and the nights are chilly but not freezing, the brightest colorations usually develop.

Mexico City is served by the Sistema de Transporte Colectivo, a 225.9 km (140 mi) metro system, which is the largest in Latin America. The first portions were opened in 1969 and it has expanded to 12 lines with 195 stations. The metro is one of the busiest in the world transporting approximately 4.5 million people every day, surpassed only by subway lines in Moscow (7.5 million), Tokyo (5.9 million), and New York City (5.1 million). It is heavily subsidized, and has some of the lowest fares in the world, each trip costing 5.00 pesos from 05:00 am to midnight. Several stations display pre-Columbian artifacts and architecture that were discovered during the metro's construction.[citation needed] However, the metro covers less than half of the total urban area. The Metro stations are also differentiated by the use of icons and glyphs which were proposed for people who could not read. The specific icons were developed based on historical (characters, sites, pre-Hispanic motifs), linguistic, symbolic (glyphs) or location references and has being emulated in further transportations alternatives in the City and in other Mexican cities. Mexico City is the only city in the world to use the icon reference and has become a popular culture trademark for the city.

From his diagrams of a small number of particles interacting in spacetime, Feynman could then model all of physics in terms of the spins of those particles and the range of coupling of the fundamental forces. Feynman attempted an explanation of the strong interactions governing nucleons scattering called the parton model. The parton model emerged as a complement to the quark model developed by his Caltech colleague Murray Gell-Mann. The relationship between the two models was murky; Gell-Mann referred to Feynman's partons derisively as "put-ons". In the mid-1960s, physicists believed that quarks were just a bookkeeping device for symmetry numbers, not real particles, as the statistics of the Omega-minus particle, if it were interpreted as three identical strange quarks bound together, seemed impossible if quarks were real. The Stanford linear accelerator deep inelastic scattering experiments of the late 1960s showed, analogously to Ernest Rutherford's experiment of scattering alpha particles on gold nuclei in 1911, that nucleons (protons and neutrons) contained point-like particles that scattered electrons. It was natural to identify these with quarks, but Feynman's parton model attempted to interpret the experimental data in a way that did not introduce additional hypotheses. For example, the data showed that some 45% of the energy momentum was carried by electrically-neutral particles in the nucleon. These electrically-neutral particles are now seen to be the gluons that carry the forces between the quarks and carry also the three-valued color quantum number that solves the Omega-minus problem. Feynman did not dispute the quark model; for example, when the fifth quark was discovered in 1977, Feynman immediately pointed out to his students that the discovery implied the existence of a sixth quark, which was discovered in the decade after his death.

Dell's reputation for poor customer service, since 2002, which was exacerbated as it moved call centres offshore and as its growth outstripped its technical support infrastructure, came under increasing scrutiny on the Web. The original Dell model was known for high customer satisfaction when PCs sold for thousands but by the 2000s, the company could not justify that level of service when computers in the same lineup sold for hundreds. Rollins responded by shifting Dick Hunter from head of manufacturing to head of customer service. Hunter, who noted that Dell's DNA of cost-cutting "got in the way," aimed to reduce call transfer times and have call center representatives resolve inquiries in one call. By 2006, Dell had spent $100 million in just a few months to improve on this, and rolled out DellConnect to answer customer inquiries more quickly. In July 2006, the company started its Direct2Dell blog, and then in February 2007, Michael Dell launched IdeaStorm.com, asking customers for advice including selling Linux computers and reducing the promotional "bloatware" on PCs. These initiatives did manage to cut the negative blog posts from 49% to 22%, as well as reduce the "Dell Hell" prominent on Internet search engines.

Symmetry groups are groups consisting of symmetries of given mathematical objects—be they of geometric nature, such as the introductory symmetry group of the square, or of algebraic nature, such as polynomial equations and their solutions. Conceptually, group theory can be thought of as the study of symmetry.t[›] Symmetries in mathematics greatly simplify the study of geometrical or analytical objects. A group is said to act on another mathematical object X if every group element performs some operation on X compatibly to the group law. In the rightmost example below, an element of order 7 of the (2,3,7) triangle group acts on the tiling by permuting the highlighted warped triangles (and the other ones, too). By a group action, the group pattern is connected to the structure of the object being acted on.

While H2 is not very reactive under standard conditions, it does form compounds with most elements. Hydrogen can form compounds with elements that are more electronegative, such as halogens (e.g., F, Cl, Br, I), or oxygen; in these compounds hydrogen takes on a partial positive charge. When bonded to fluorine, oxygen, or nitrogen, hydrogen can participate in a form of medium-strength noncovalent bonding with other similar molecules between their hydrogens called hydrogen bonding, which is critical to the stability of many biological molecules. Hydrogen also forms compounds with less electronegative elements, such as the metals and metalloids, in which it takes on a partial negative charge. These compounds are often known as hydrides.

On 8 June 1856, the next settlement began on Norfolk Island. These were the descendants of Tahitians and the HMS Bounty mutineers, including those of Fletcher Christian. They resettled from the Pitcairn Islands, which had become too small for their growing population. On 3 May 1856, 193 persons left Pitcairn Islands aboard the "Morayshire". On 8 June 194 persons arrived, a baby having been born in transit. The Pitcairners occupied many of the buildings remaining from the penal settlements, and gradually established traditional farming and whaling industries on the island. Although some families decided to return to Pitcairn in 1858 and 1863, the island's population continued to grow. They accepted additional settlers, who often arrived with whaling fleets.

In an essay on Sephardi Jewry, Daniel Elazar at the Jerusalem Center for Public Affairs summarized the demographic history of Ashkenazi Jews in the last thousand years, noting that at the end of the 11th century, 97% of world Jewry was Sephardic and 3% Ashkenazi; by the end of XVI century, the: 'Treaty on the redemption of captives', by Gracian of the God's Mother, Mercy Priest, who was imprisoned by Turks, cites a Tunisian Hebrew, made captive when arriving to Gaeta, who aided others with money, named: 'Simon Escanasi', in the mid-17th century, "Sephardim still outnumbered Ashkenazim three to two", but by the end of the 18th century, "Ashkenazim outnumbered Sephardim three to two, the result of improved living conditions in Christian Europe versus the Ottoman Muslim world." By 1931, Ashkenazi Jews accounted for nearly 92% of world Jewry. These factors are sheer demography showing the migration patterns of Jews from Southern and Western Europe to Central and Eastern Europe.

This means that a newly appointed constable has the same arrest powers as a Chief Constable or Commissioner. However, certain higher ranks have additional powers to authorize certain aspects of police operations, such as a power to authorize a search of a suspect's house (section 18 PACE in England and Wales) by an officer of the rank of Inspector, or the power to authorize a suspect's detention beyond 24 hours by a Superintendent.

The Scientific Revolution was a period when European ideas in classical physics, astronomy, biology, human anatomy, chemistry, and other classical sciences were rejected and led to doctrines supplanting those that had prevailed from Ancient Greece to the Middle Ages which would lead to a transition to modern science. This period saw a fundamental transformation in scientific ideas across physics, astronomy, and biology, in institutions supporting scientific investigation, and in the more widely held picture of the universe. Individuals started to question all manners of things and it was this questioning that led to the Scientific Revolution, which in turn formed the foundations of contemporary sciences and the establishment of several modern scientific fields.

In 1978, Sewall Wright suggested that human populations that have long inhabited separated parts of the world should, in general, be considered different subspecies by the usual criterion that most individuals of such populations can be allocated correctly by inspection. Wright argued that it does not require a trained anthropologist to classify an array of Englishmen, West Africans, and Chinese with 100% accuracy by features, skin color, and type of hair despite so much variability within each of these groups that every individual can easily be distinguished from every other. However, it is customary to use the term race rather than subspecies for the major subdivisions of the human species as well as for minor ones.

Breathing is largely driven by the muscular diaphragm, which divides the thorax from the abdominal cavity, forming a dome with its convexity towards the thorax. Contraction of the diaphragm flattens the dome, increasing the volume of the cavity in which the lung is enclosed. Air enters through the oral and nasal cavities; it flows through the larynx, trachea and bronchi and expands the alveoli. Relaxation of the diaphragm has the opposite effect, passively recoiling during normal breathing. During exercise, the abdominal wall contracts, increasing visceral pressure on the diaphragm, thus forcing the air out more quickly and forcefully. The rib cage itself also is able to expand and contract the thoracic cavity to some degree, through the action of other respiratory and accessory respiratory muscles. As a result, air is sucked into or expelled out of the lungs, always moving down its pressure gradient. This type of lung is known as a bellows lung as it resembles a blacksmith's bellows. Mammals take oxygen into their lungs, and discard carbon dioxide.

Within months of beginning his tenure as the president of the university, Eisenhower was requested to advise U.S. Secretary of Defense James Forrestal on the unification of the armed services. About six months after his appointment, he became the informal Chairman of the Joint Chiefs of Staff in Washington. Two months later he fell ill, and he spent over a month in recovery at the Augusta National Golf Club. He returned to his post in New York in mid-May, and in July 1949 took a two-month vacation out-of-state. Because the American Assembly had begun to take shape, he traveled around the country during mid-to-late 1950, building financial support from Columbia Associates, an alumni association.

On Sentinel Peak (also known as "'A' Mountain"), just west of downtown, there is a giant "A" in honor of the University of Arizona. Starting in about 1916, a yearly tradition developed for freshmen to whitewash the "A", which was visible for miles. However, at the beginning of the Iraq War, anti-war activists painted it black. This was followed by a paint scuffle where the "A" was painted various colors until the city council intervened. It is now red, white and blue except when it is white or another color decided by a biennial election. Because of the three-color paint scheme often used, the shape of the A can be vague and indistinguishable from the rest of the peak. The top of Sentinel Peak, which is accessible by road, offers an outstanding scenic view of the city looking eastward. A parking lot located near the summit of Sentinel Peak was formerly a popular place to watch sunsets or view the city lights at night.

The rapid expansion of the Rus' to the south led to conflict and volatile relationships with the Khazars and other neighbors on the Pontic steppe. The Khazars dominated the Black Sea steppe during the 8th century, trading and frequently allying with the Byzantine Empire against Persians and Arabs. In the late 8th century, the collapse of the Göktürk Khaganate led the Magyars and the Pechenegs, Ugric and Turkic peoples from Central Asia, to migrate west into the steppe region, leading to military conflict, disruption of trade, and instability within the Khazar Khaganate. The Rus' and Slavs had earlier allied with the Khazars against Arab raids on the Caucasus, but they increasingly worked against them to secure control of the trade routes.

One of the few stirs arose when the Canadian Prime Minister, R. B. Bennett, considered the Duke for Governor General of Canada in 1931—a proposal that King George V rejected on the advice of the Secretary of State for Dominion Affairs, J. H. Thomas.

Breakthrough pain is transitory acute pain that comes on suddenly and is not alleviated by the patient's normal pain management. It is common in cancer patients who often have background pain that is generally well-controlled by medications, but who also sometimes experience bouts of severe pain that from time to time "breaks through" the medication. The characteristics of breakthrough cancer pain vary from person to person and according to the cause. Management of breakthrough pain can entail intensive use of opioids, including fentanyl.

As a consequence, there was a crisis in international confidence in Greece's ability to repay its sovereign debt, as reflected by the rise of the country's borrowing rates (although their slow rise – the 10-year government bond yield only exceeded 7% in April 2010 – coinciding with a large number of negative articles, has led to arguments about the role of international news media in the evolution of the crisis). In order to avert a default (as high borrowing rates effectively prohibited access to the markets), in May 2010 the other Eurozone countries, and the IMF, agreed to a "rescue package" which involved giving Greece an immediate €45 billion in bail-out loans, with more funds to follow, totaling €110 billion. In order to secure the funding, Greece was required to adopt harsh austerity measures to bring its deficit under control. Their implementation will be monitored and evaluated by the European Commission, the European Central Bank and the IMF.

Like in English, Dutch has generalised the dative over the accusative case for all pronouns, e.g. Du me, je, Eng me, you, vs. Germ mich/mir dich/dir. There is one exception: the standard language prescribes that in the third person plural, hen is to be used for the direct object, and hun for the indirect object. This distinction was artificially introduced in the 17th century by grammarians, and is largely ignored in spoken language and not well understood by Dutch speakers. Consequently, the third person plural forms hun and hen are interchangeable in normal usage, with hun being more common. The shared unstressed form ze is also often used as both direct and indirect objects and is a useful avoidance strategy when people are unsure which form to use.

At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzińska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 1838–39 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.

The consensus view in contemporary paleontology is that the flying theropods, or avialans, are the closest relatives of the deinonychosaurs, which include dromaeosaurids and troodontids. Together, these form a group called Paraves. Some basal members of this group, such as Microraptor, have features which may have enabled them to glide or fly. The most basal deinonychosaurs were very small. This evidence raises the possibility that the ancestor of all paravians may have been arboreal, have been able to glide, or both. Unlike Archaeopteryx and the non-avialan feathered dinosaurs, who primarily ate meat, recent studies suggest that the first avialans were omnivores.

Pāśupatas divided the created world into the insentient and the sentient. The insentient was the unconscious and thus dependent on the sentient or conscious. The insentient was further divided into effects and causes. The effects were of ten kinds, the earth, four elements and their qualities, colour etc. The causes were of thirteen kinds, the five organs of cognition, the five organs of action, the three internal organs, intellect, the ego principle and the cognising principle. These insentient causes were held responsible for the illusive identification of Self with non-Self. Salvation in Pāśupata involved the union of the soul with God through the intellect.

Nanjing has a humid subtropical climate (Köppen Cfa) and is under the influence of the East Asian monsoon. The four seasons are distinct, with damp conditions seen throughout the year, very hot and muggy summers, cold, damp winters, and in between, spring and autumn are of reasonable length. Along with Chongqing and Wuhan, Nanjing is traditionally referred to as one of the "Three Furnacelike Cities" along the Yangtze River (长江流域三大火炉) for the perennially high temperatures in the summertime. However, the time from mid-June to the end of July is the plum blossom blooming season in which the meiyu (rainy season of East Asia; literally "plum rain") occurs, during which the city experiences a period of mild rain as well as dampness. Typhoons are uncommon but possible in the late stages of summer and early part of autumn. The annual mean temperature is around 15.46 °C (59.8 °F), with the monthly 24-hour average temperature ranging from 2.4 °C (36.3 °F) in January to 27.8 °C (82.0 °F) in July. Extremes since 1951 have ranged from −14.0 °C (7 °F) on 6 January 1955 to 40.7 °C (105 °F) on 22 August 1959. On average precipitation falls 115 days out of the year, and the average annual rainfall is 1,062 millimetres (42 in). With monthly percent possible sunshine ranging from 37 percent in March to 52 percent in August, the city receives 1,983 hours of bright sunshine annually.

Soon after the defeat of the Spanish Armada in 1588, London merchants presented a petition to Queen Elizabeth I for permission to sail to the Indian Ocean. The permission was granted, and despite the defeat of the English Armada in 1589, on 10 April 1591 three ships sailed from Torbay around the Cape of Good Hope to the Arabian Sea on one of the earliest English overseas Indian expeditions. One of them, Edward Bonventure, then sailed around Cape Comorin and on to the Malay Peninsula and subsequently returned to England in 1594.

Andreesen's browser sparked the internet boom of the 1990s. The introduction of Mosaic in 1993 – one of the first graphical web browsers – led to an explosion in web use. Andreessen, the leader of the Mosaic team at National Center for Supercomputing Applications (NCSA), soon started his own company, named Netscape, and released the Mosaic-influenced Netscape Navigator in 1994, which quickly became the world's most popular browser, accounting for 90% of all web use at its peak (see usage share of web browsers).

These live their lives as scavengers and have never been owned by humans, with one study showing their most common response when approached by strangers was to run away (52%) or respond with aggression (11%). We know little about these dogs, nor about the dogs that live in developed countries that are feral, stray or are in shelters, yet the great majority of modern research on dog cognition has focused on pet dogs living in human homes.

Though still a graphical wrapper that relied upon MS-DOS, 3.0 was the first iteration of Windows which had a feature set and performance comparable to the much more expensive Macintosh platform. It also did not help matters that during the previous year Jean-Louis Gassée had steadfastly refused to lower the profit margins on Mac computers. Finally, there was a component shortage that rocked the exponentially-expanding PC industry in 1989, forcing Apple USA head Allan Loren to cut prices which dropped Apple's margins.

The 9th- and 10th-century mosaics of the Hagia Sophia in Constantinople are truly classical Byzantine artworks. The north and south tympana beneath the dome was decorated with figures of prophets, saints and patriarchs. Above the principal door from the narthex we can see an Emperor kneeling before Christ (late 9th or early 10th century). Above the door from the southwest vestibule to the narthex another mosaic shows the Theotokos with Justinian and Constantine. Justinian I is offering the model of the church to Mary while Constantine is holding a model of the city in his hand. Both emperors are beardless – this is an example for conscious archaization as contemporary Byzantine rulers were bearded. A mosaic panel on the gallery shows Christ with Constantine Monomachos and Empress Zoe (1042–1055). The emperor gives a bulging money sack to Christ as a donation for the church.

The study of genocide has mainly been focused towards the legal aspect of the term. By formally recognizing the act of genocide as a crime, involves the undergoing prosecution that begins with not only seeing genocide as outrageous past any moral standpoint but also may be a legal liability within international relations. When genocide is looked at in a general aspect it is viewed as the deliberate killing of a certain group. Yet is commonly seen to escape the process of trial and prosecution due to the fact that genocide is more often than not committed by the officials in power of a state or area. In 1648 before the term genocide had been coined, the Peace of Westphalia was established to protect ethnic, national, racial and in some instances religious groups. During the 19th century humanitarian intervention was needed due to the fact of conflict and justification of some of the actions executed by the military.

iPods with color displays use anti-aliased graphics and text, with sliding animations. All iPods (except the 3rd-generation iPod Shuffle, the 6th & 7th generation iPod Nano, and iPod Touch) have five buttons and the later generations have the buttons integrated into the click wheel – an innovation that gives an uncluttered, minimalist interface. The buttons perform basic functions such as menu, play, pause, next track, and previous track. Other operations, such as scrolling through menu items and controlling the volume, are performed by using the click wheel in a rotational manner. The 3rd-generation iPod Shuffle does not have any controls on the actual player; instead it has a small control on the earphone cable, with volume-up and -down buttons and a single button for play and pause, next track, etc. The iPod Touch has no click-wheel; instead it uses a 3.5" touch screen along with a home button, sleep/wake button and (on the second and third generations of the iPod Touch) volume-up and -down buttons. The user interface for the iPod Touch is identical to that of the iPhone. Differences include a lack of a phone application. Both devices use iOS.

In 1742, fearing the monetary consequences of a war, the British government agreed to extend the deadline for the licensed exclusive trade by the company in India until 1783, in return for a further loan of £1 million. Between 1756 and 1763, the Seven Years' War diverted the state's attention towards consolidation and defence of its territorial possessions in Europe and its colonies in North America.

Literary techniques encompass a wide range of approaches to crafting a work: whether a work is narrated in first-person or from another perspective, whether to use a traditional linear narrative or a nonlinear narrative, or the choice of literary genre, are all examples of literary technique. They may indicate to a reader that there is a familiar structure and presentation to a work, such as a conventional murder-mystery novel; or, the author may choose to experiment with their technique to surprise the reader.

Unlike most languages that use alphabets to indicate the pronunciation, Chinese characters have developed from logograms that do not always give hints to its pronunciation. Although the written characters remained relatively consistent for the last two thousand years, the pronunciation and grammar in different regions has developed to an extent that the varieties of the spoken language are often mutually unintelligible. As a series of migration to the south throughout the history, the regional languages of the south, including Xiang, Wu, Gan, Min, Yue (Cantonese), and Hakka often show traces of Old Chinese or Middle Chinese. From the Ming dynasty onward, Beijing has been the capital of China and the dialect spoken in Beijing has had the most prestige among other varieties. With the founding of the Republic of China, Standard Mandarin was designated as the official language, based on the spoken language of Beijing. Since then, other spoken varieties are regarded as fangyan (dialects). Cantonese is still the most commonly used language in Hong Kong, Macau and among some overseas Chinese communities, whereas Southern Min has been accepted in Taiwan as an important local language along with Mandarin.

Charles Peirce (1839–1914) was highly influential in laying the groundwork for today's empirical scientific method.[citation needed] Although Peirce severely criticized many elements of Descartes' peculiar brand of rationalism, he did not reject rationalism outright. Indeed, he concurred with the main ideas of rationalism, most importantly the idea that rational concepts can be meaningful and the idea that rational concepts necessarily go beyond the data given by empirical observation. In later years he even emphasized the concept-driven side of the then ongoing debate between strict empiricism and strict rationalism, in part to counterbalance the excesses to which some of his cohorts had taken pragmatism under the "data-driven" strict-empiricist view.

In Johannine "agent Christology" the submission of Jesus to crucifixion is a sacrifice made as an agent of God or servant of God, for the sake of eventual victory. This builds on the salvific theme of the Gospel of John which begins in John 1:29 with John the Baptist's proclamation: "The Lamb of God who takes away the sins of the world". Further reinforcement of the concept is provided in Revelation 21:14 where the "lamb slain but standing" is the only one worthy of handling the scroll (i.e. the book) containing the names of those who are to be saved.

In addition to the true folded mountains, known as the ridge and valley province, the area of dissected plateau to the north and west of the mountains is usually grouped with the Appalachians. This includes the Catskill Mountains of southeastern New York, the Poconos in Pennsylvania, and the Allegheny Plateau of southwestern New York, western Pennsylvania, eastern Ohio and northern West Virginia. This same plateau is known as the Cumberland Plateau in southern West Virginia, eastern Kentucky, western Virginia, eastern Tennessee, and northern Alabama.

Stepper motors are a type of motor frequently used when precise rotations are required. In a stepper motor an internal rotor containing PMs or a magnetically soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it "steps"—starts and then quickly stops again—from one position to the next as field windings are energized and de-energized in sequence. Depending on the sequence, the rotor may turn forwards or backwards, and it may change direction, stop, speed up or slow down arbitrarily at any time.

Pan-Germanism's origins began in the early 19th century following the Napoleonic Wars. The wars launched a new movement that was born in France itself during the French Revolution. Nationalism during the 19th century threatened the old aristocratic regimes. Many ethnic groups of Central and Eastern Europe had been divided for centuries, ruled over by the old Monarchies of the Romanovs and the Habsburgs. Germans, for the most part, had been a loose and disunited people since the Reformation when the Holy Roman Empire was shattered into a patchwork of states. The new German nationalists, mostly young reformers such as Johann Tillmann of East Prussia, sought to unite all the German-speaking and ethnic-German (Volksdeutsche) people.

The British and French struggles in India became but one theatre of the global Seven Years' War (1756–1763) involving France, Britain and the other major European powers. The signing of the Treaty of Paris (1763) had important consequences for the future of the British Empire. In North America, France's future as a colonial power there was effectively ended with the recognition of British claims to Rupert's Land, and the ceding of New France to Britain (leaving a sizeable French-speaking population under British control) and Louisiana to Spain. Spain ceded Florida to Britain. Along with its victory over France in India, the Seven Years' War therefore left Britain as the world's most powerful maritime power.

It has been mentioned that most nonprofits will never be able to match the pay of the private sector and therefore should focus their attention on benefits packages, incentives and implementing pleasurable work environments. Pleasurable work conditions are ranked as being more preferable than a high salary and implacable work. NPOs are encouraged to pay as much as they are able, and offer a low stress work environment that the employee can associate him or herself positively with. Other incentives that should be implemented are generous vacation allowances or flexible work hours.

Robert N. Bellah has in his writings that although the separation of church and state is grounded firmly in the constitution of the United States, this does not mean that there is no religious dimension in the political society of the United States. He used the term "Civil Religion" to describe the specific relation between politics and religion in the United States. His 1967 article analyzes the inaugural speech of John F. Kennedy: "Considering the separation of church and state, how is a president justified in using the word 'God' at all? The answer is that the separation of church and state has not denied the political realm a religious dimension."

Operational Acceptance is used to conduct operational readiness (pre-release) of a product, service or system as part of a quality management system. OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. This type of testing focuses on the operational readiness of the system to be supported, and/or to become part of the production environment. Hence, it is also known as operational readiness testing (ORT) or Operations readiness and assurance (OR&A) testing. Functional testing within OAT is limited to those tests which are required to verify the non-functional aspects of the system.

The 1469 marriage of Isabella I of Castile and Ferdinand II of Aragon and the 1479 death of John II of Aragon led to the creation of modern-day Spain. In 1492, Granada was captured from the Moors, thereby completing the Reconquista. Portugal had during the 15th century – particularly under Henry the Navigator – gradually explored the coast of Africa, and in 1498, Vasco da Gama found the sea route to India. The Spanish monarchs met the Portuguese challenge by financing the expedition of Christopher Columbus to find a western sea route to India, leading to the discovery of the Americas in 1492.

Feeding structures in the mouth region vary widely, and have little correlation with the animals' diets. Many polychaetes have a muscular pharynx that can be everted (turned inside out to extend it). In these animals the foremost few segments often lack septa so that, when the muscles in these segments contract, the sharp increase in fluid pressure from all these segments everts the pharynx very quickly. Two families, the Eunicidae and Phyllodocidae, have evolved jaws, which can be used for seizing prey, biting off pieces of vegetation, or grasping dead and decaying matter. On the other hand, some predatory polychaetes have neither jaws nor eversible pharynges. Selective deposit feeders generally live in tubes on the sea-floor and use palps to find food particles in the sediment and then wipe them into their mouths. Filter feeders use "crowns" of palps covered in cilia that wash food particles towards their mouths. Non-selective deposit feeders ingest soil or marine sediments via mouths that are generally unspecialized. Some clitellates have sticky pads in the roofs of their mouths, and some of these can evert the pads to capture prey. Leeches often have an eversible proboscis, or a muscular pharynx with two or three teeth.

John Calvin supported the "agent of God" Christology and argued that in his trial in Pilate's Court Jesus could have successfully argued for his innocence, but instead submitted to crucifixion in obedience to the Father. This Christological theme continued into the 20th century, both in the Eastern and Western Churches. In the Eastern Church Sergei Bulgakov argued that the crucifixion of Jesus was "pre-eternally" determined by the Father before the creation of the world, to redeem humanity from the disgrace caused by the fall of Adam. In the Western Church, Karl Rahner elaborated on the analogy that the blood of the Lamb of God (and the water from the side of Jesus) shed at the crucifixion had a cleansing nature, similar to baptismal water.

Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.

The World Intellectual Property Organization (WIPO) recognizes that conflicts may exist between the respect for and implementation of current intellectual property systems and other human rights. In 2001 the UN Committee on Economic, Social and Cultural Rights issued a document called "Human rights and intellectual property" that argued that intellectual property tends to be governed by economic goals when it should be viewed primarily as a social product; in order to serve human well-being, intellectual property systems must respect and conform to human rights laws. According to the Committee, when systems fail to do so they risk infringing upon the human right to food and health, and to cultural participation and scientific benefits. In 2004 the General Assembly of WIPO adopted The Geneva Declaration on the Future of the World Intellectual Property Organization which argues that WIPO should "focus more on the needs of developing countries, and to view IP as one of many tools for development—not as an end in itself".

The flag of the Communist Party of China became a red banner with a hammer and sickle, similar to that on the Soviet flag. In the 1950s and 1960s, other Communist regimes such as Vietnam and Laos also adopted red flags. Some Communist countries, such as Cuba, chose to keep their old flags; and other countries used red flags which had nothing to do with Communism or socialism; the red flag of Nepal, for instance, represents the national flower.

Provide Campaign Assistance. Minority leaders are typically energetic and aggressive campaigners for partisan incumbents and challengers. There is hardly any major aspect of campaigning that does not engage their attention. For example, they assist in recruiting qualified candidates; they establish "leadership PACs" to raise and distribute funds to House candidates of their party; they try to persuade partisan colleagues not to retire or run for other offices so as to hold down the number of open seats the party would need to defend; they coordinate their campaign activities with congressional and national party campaign committees; they encourage outside groups to back their candidates; they travel around the country to speak on behalf of party candidates; and they encourage incumbent colleagues to make significant financial contributions to the party's campaign committee.

When Faubus balked, the president placed the Arkansas National Guard under federal control and sent in the 101st Airborne Division. They escorted and protected nine black students' entry to Little Rock Central High School, an all-white public school, for the first time since the Reconstruction Era.

Exposure to antibiotics early in life is associated with increased body mass in humans and mouse models. Early life is a critical period for the establishment of the intestinal microbiota and for metabolic development. Mice exposed to subtherapeutic antibiotic treatment (STAT)– with either penicillin, vancomycin, penicillin and vancomycin, or chlortetracycline had altered composition of the gut microbiota as well as its metabolic capabilities. Moreover, research have shown that mice given low-dose penicillin (1 μg/g body weight) around birth and throughout the weaning process had an increased body mass and fat mass, accelerated growth, and increased hepatic expression of genes involved in adipogenesis, compared to controlled mice. In addition, penicillin in combination with a high-fat diet increased fasting insulin levels in mice. However, it is unclear whether or not antibiotics cause obesity in humans. Studies have found a correlation between early exposure of antibiotics (<6 months) and increased body mass (at 10 and 20 months). Another study found that the type of antibiotic exposure was also significant with the highest risk of being overweight in those given macrolides compared to penicillin and cephalosporin. Therefore, there is correlation between antibiotic exposure in early life and obesity in humans, but whether or not there is a causal relationship remains unclear. Although there is a correlation between antibiotic use in early life and obesity, the effect of antibiotics on obesity in humans needs to be weighed against the beneficial effects of clinically indicated treatment with antibiotics in infancy.

The heavy infantry of the maniples were supported by a number of light infantry and cavalry troops, typically 300 horsemen per manipular legion. The cavalry was drawn primarily from the richest class of equestrians. There was an additional class of troops who followed the army without specific martial roles and were deployed to the rear of the third line. Their role in accompanying the army was primarily to supply any vacancies that might occur in the maniples. The light infantry consisted of 1,200 unarmoured skirmishing troops drawn from the youngest and lower social classes.

An additional extension to MPEG-2 is named MPEG-2.5 audio, as MPEG-3 already had a different meaning. This extension was developed at Fraunhofer IIS, the registered MP3 patent holders. Like MPEG-2, MPEG-2.5 adds new sampling rates exactly half of that previously possible with MPEG-2. It thus widens the scope of MP3 to include human speech and other applications requiring only 25% of the frequency reproduction possible with MPEG-1. While not an ISO recognized standard, MPEG-2.5 is widely supported by both inexpensive and brand name digital audio players as well as computer software based MP3 encoders and decoders. A sample rate comparison between MPEG-1, 2 and 2.5 is given further down. MPEG-2.5 was not developed by MPEG and was never approved as an international standard.

In offices, both men and women often dress in suits. Traditional clothing for Christian Tigrinya-speaking highlanders consists of bright white gowns called zurias for the women, and long white shirts accompanied by white pants for the men. In Muslim communities in the Eritrean lowland, the women traditionally dress in brightly colored clothes.

Unlike these diseases, the airway obstruction in asthma is usually reversible; however, if left untreated, the chronic inflammation from asthma can lead the lungs to become irreversibly obstructed due to airway remodeling.

The sensors are primarily single cells that detect light, chemicals, pressure waves and contact, and are present on the head, appendages (if any) and other parts of the body. Nuchal ("on the neck") organs are paired, ciliated structures found only in polychaetes, and are thought to be chemosensors. Some polychaetes also have various combinations of ocelli ("little eyes") that detect the direction from which light is coming and camera eyes or compound eyes that can probably form images. The compound eyes probably evolved independently of arthropods' eyes. Some tube-worms use ocelli widely spread over their bodies to detect the shadows of fish, so that they can quickly withdraw into their tubes. Some burrowing and tube-dwelling polychaetes have statocysts (tilt and balance sensors) that tell them which way is down. A few polychaete genera have on the undersides of their heads palps that are used both in feeding and as "feelers", and some of these also have antennae that are structurally similar but probably are used mainly as "feelers".

Although chartered as a university, for many years Washington University functioned primarily as a night school located on 17th Street and Washington Avenue in the heart of downtown St. Louis. Owing to limited financial resources, Washington University initially used public buildings. Classes began on October 22, 1854, at the Benton School building. At first the university paid for the evening classes, but as their popularity grew, their funding was transferred to the St. Louis Public Schools. Eventually the board secured funds for the construction of Academic Hall and a half dozen other buildings. Later the university divided into three departments: the Manual Training School, Smith Academy, and the Mary Institute.

According to mtDNA studies by Holden (2005) and Richards et al. (2006), a significant proportion of the maternal lineages of Somalis consists of the M1 haplogroup. This mitochondrial clade is common among Ethiopians and North Africans, particularly Egyptians and Algerians. M1 is believed to have originated in Asia, where its parent M clade represents the majority of mtDNA lineages. This haplogroup is also thought to possibly correlate with the Afro-Asiatic language family:

In Darwin's time there was no agreed-upon model of heredity; in Chapter I Darwin admitted, "The laws governing inheritance are quite unknown." He accepted a version of the inheritance of acquired characteristics (which after Darwin's death came to be called Lamarckism), and Chapter V discusses what he called the effects of use and disuse; he wrote that he thought "there can be little doubt that use in our domestic animals strengthens and enlarges certain parts, and disuse diminishes them; and that such modifications are inherited", and that this also applied in nature. Darwin stated that some changes that were commonly attributed to use and disuse, such as the loss of functional wings in some island dwelling insects, might be produced by natural selection. In later editions of Origin, Darwin expanded the role attributed to the inheritance of acquired characteristics. Darwin also admitted ignorance of the source of inheritable variations, but speculated they might be produced by environmental factors. However, one thing was clear: whatever the exact nature and causes of new variations, Darwin knew from observation and experiment that breeders were able to select such variations and produce huge differences in many generations of selection. The observation that selection works in domestic animals is not destroyed by lack of understanding of the underlying hereditary mechanism.

In the 19th century, musical institutions emerged from the control of wealthy patrons, as composers and musicians could construct lives independent of the nobility. Increasing interest in music by the growing middle classes throughout western Europe spurred the creation of organizations for the teaching, performance, and preservation of music. The piano, which achieved its modern construction in this era (in part due to industrial advances in metallurgy) became widely popular with the middle class, whose demands for the instrument spurred a large number of piano builders. Many symphony orchestras date their founding to this era. Some musicians and composers were the stars of the day; some, like Franz Liszt and Niccolò Paganini, fulfilled both roles.

Even at high latitudes, glacier formation is not inevitable. Areas of the Arctic, such as Banks Island, and the McMurdo Dry Valleys in Antarctica are considered polar deserts where glaciers cannot form because they receive little snowfall despite the bitter cold. Cold air, unlike warm air, is unable to transport much water vapor. Even during glacial periods of the Quaternary, Manchuria, lowland Siberia, and central and northern Alaska, though extraordinarily cold, had such light snowfall that glaciers could not form.

To prevent piracy of films, the standard drill of film distribution is to have a movie first released through movie theaters (theatrical window), on average approximately 16 and a half weeks, before having it released to Blu-Ray and DVD (entering its video window). During the theatrical window, digital versions of films are often transported in data storage devices by couriers rather than by data transmission. The data can be encrypted, with the key being made to work only at specific times in order to prevent leakage between screens. Coded Anti-Piracy marks can be added to films to identify the source of illegal copies and shut them down. As a result of these measures, the only versions of films available for piracy during the theatrical window are usually "cams" made by video recordings of the movie screens, which are of inferior quality compared to the original film version.
