Although provision is made in Title 10 of the United States Code for the Secretary of the Air Force to appoint warrant officers, the Air Force does not currently use warrant officer grades, and is the only one of the U.S. Armed Services not to do so. The Air Force inherited warrant officer ranks from the Army at its inception in 1947, but their place in the Air Force structure was never made clear.[citation needed] When the Congress authorized the creation of two new senior enlisted ranks in 1958, Air Force officials privately concluded that these two new "super grades" could fill all Air Force needs then performed at the warrant officer level, although this was not publicly acknowledged until years later.[citation needed] The Air Force stopped appointing warrant officers in 1959, the same year the first promotions were made to the new top enlisted grade, Chief Master Sergeant. Most of the existing Air Force warrant officers entered the commissioned officer ranks during the 1960s, but small numbers continued to exist in the warrant officer grades for the next 21 years.

Microsoft Windows keeps the system real-time clock in local time. This causes several problems, including compatibility when multi booting with operating systems that set the clock to UTC, and double-adjusting the clock when multi booting different Windows versions, such as with a rescue boot disk. This approach is a problem even in Windows-only systems: there is no support for per-user timezone settings, only a single system-wide setting. In 2008 Microsoft hinted that future versions of Windows will partially support a Windows registry entry RealTimeIsUniversal that had been introduced many years earlier, when Windows NT supported RISC machines with UTC clocks, but had not been maintained. Since then at least two fixes related to this feature have been published by Microsoft.

Question: Since 2008, at least how many times has Microsoft released fixes for the RealTimeIsUniversal feature?
Answer: two.

In the wake of these external defeats, the Guangxu Emperor initiated the Hundred Days' Reform of 1898. Newer, more radical advisers such as Kang Youwei were given positions of influence. The emperor issued a series of edicts and plans were made to reorganize the bureaucracy, restructure the school system, and appoint new officials. Opposition from the bureaucracy was immediate and intense. Although she had been involved in the initial reforms, the empress dowager stepped in to call them off, arrested and executed several reformers, and took over day-to-day control of policy. Yet many of the plans stayed in place, and the goals of reform were implanted.

Many hunter-gatherers consciously manipulate the landscape through cutting or burning undesirable plants while encouraging desirable ones, some even going to the extent of slash-and-burn to create habitat for game animals. These activities are on an entirely different scale to those associated with agriculture, but they are nevertheless domestication on some level. Today, almost all hunter-gatherers depend to some extent upon domesticated food sources either produced part-time or traded for products acquired in the wild.

Question: How do they manage the landscape?
Answer: cutting or burning undesirable plants.

Sub- and quotient groups are related in the following way: a subset H of G can be seen as an injective map H → G, i.e. any element of the target has at most one element that maps to it. The counterpart to injective maps are surjective maps (every element of the target is mapped onto), such as the canonical map G → G / N.y[›] Interpreting subgroup and quotients in light of these homomorphisms emphasizes the structural concept inherent to these definitions alluded to in the introduction. In general, homomorphisms are neither injective nor surjective. Kernel and image of group homomorphisms and the first isomorphism theorem address this phenomenon.

Question: What map shows the relation between sub and quotient groups?
Answer: injective map.

The concept's origins can potentially be traced back further. Jewish law includes several considerations whose effects are similar to those of modern intellectual property laws, though the notion of intellectual creations as property does not seem to exist – notably the principle of Hasagat Ge'vul (unfair encroachment) was used to justify limited-term publisher (but not author) copyright in the 16th century. In 500 BCE, the government of the Greek state of Sybaris offered one year's patent "to all who should discover any new refinement in luxury".

This nationwide acceptance and recognition of Aboriginal people led to a significant increase in the number of people self-identifying as Aboriginal or Torres Strait Islander. The reappropriation of the term "black" with a positive and more inclusive meaning has resulted in its widespread use in mainstream Australian culture, including public media outlets, government agencies, and private companies. In 2012, a number of high-profile cases highlighted the legal and community attitude that identifying as Aboriginal or Torres Strait Islander is not dependent on skin colour, with a well-known boxer Anthony Mundine being widely criticised for questioning the "blackness" of another boxer and journalist Andrew Bolt being successfully sued for publishing discriminatory comments about Aboriginals with light skin.

In the Southern Russian dialects, instances of unstressed /e/ and /a/ following palatalized consonants and preceding a stressed syllable are not reduced to [ɪ] (as occurs in the Moscow dialect), being instead pronounced [a] in such positions (e.g. несли is pronounced [nʲaˈslʲi], not [nʲɪsˈlʲi]) – this is called yakanye/яканье. Consonants include a fricative /ɣ/, a semivowel /w~u̯/ and /x~xv~xw/, whereas the Standard and Northern dialects have the consonants /ɡ/, /v/, and final /l/ and /f/, respectively. The morphology features a palatalized final /tʲ/ in 3rd person forms of verbs (this is unpalatalized in the Standard and Northern dialects). Some of these features such as akanye/yakanye, a debuccalized or lenited /ɡ/, a semivowel /w~u̯/ and palatalized final /tʲ/ in 3rd person forms of verbs are also present in modern Belarusian and some dialects of Ukrainian (Eastern Polesian), indicating a linguistic continuum.

Samuel Adelstein described the Lombardi mandolin in 1893 as wider and shorter than the Neapolitan mandolin, with a shallower back and a shorter and wider neck, with six single strings to the regular mandolin's set of 4. The Lombardi was tuned C, D, A, E, B, G. The strings were fastened to the bridge like a guitar's. There were 20 frets, covering three octaves, with an additional 5 notes. When Adelstein wrote, there were no nylon strings, and the gut and single strings "do not vibrate so clearly and sweetly as the double steel string of the Neapolitan."

The cheerful crowds visiting bomb sites were so large they interfered with rescue work, pub visits increased in number (beer was never rationed), and 13,000 attended cricket at Lord's. People left shelters when told instead of refusing to leave, although many housewives reportedly enjoyed the break from housework. Some people even told government surveyors that they enjoyed air raids if they occurred occasionally, perhaps once a week. Despite the attacks, defeat in Norway and France, and the threat of invasion, overall morale remained high; a Gallup poll found only 3% of Britons expected to lose the war in May 1940, another found an 88% approval rating for Churchill in July, and a third found 89% support for his leadership in October. Support for peace negotiations declined from 29% in February. Each setback caused more civilians to volunteer to become unpaid Local Defence Volunteers, workers worked longer shifts and over weekends, contributions rose to the £5,000 "Spitfire Funds" to build fighters, and the number of work days lost to strikes in 1940 was the lowest in history.:60–63,67–68,75,78–79,215–216

In early August 2008, Iowa Labour Commissioner David Neil announced that his department had found that Agriprocessors, a kosher meatpacking company in Postville which had recently been raided by Immigration and Customs Enforcement, had employed 57 minors, some as young as 14, in violation of state law prohibiting anyone under 18 from working in a meatpacking plant. Neil announced that he was turning the case over to the state Attorney General for prosecution, claiming that his department's inquiry had discovered "egregious violations of virtually every aspect of Iowa's child labour laws." Agriprocessors claimed that it was at a loss to understand the allegations. Agriprocessors' CEO went to trial on these charges in state court on 4 May 2010. After a five-week trial he was found not guilty of all 57 charges of child labour violations by the Black Hawk County District Court jury in Waterloo, Iowa, on 7 June 2010.

From their beginnings in Sumer (now Iraq) around 3500 BC, the Mesopotamian people began to attempt to record some observations of the world with numerical data. But their observations and measurements were seemingly taken for purposes other than for elucidating scientific laws. A concrete instance of Pythagoras' law was recorded, as early as the 18th century BC: the Mesopotamian cuneiform tablet Plimpton 322 records a number of Pythagorean triplets (3,4,5) (5,12,13). ..., dated 1900 BC, possibly millennia before Pythagoras,  but an abstract formulation of the Pythagorean theorem was not.

The first settlers primarily came from England, its Caribbean colony of Barbados, and its Atlantic colony of Bermuda. Among these were free people of color, born in the West Indies of alliances and marriages between Africans and Englanders, when color lines were looser among the working class in the early colonial years, and some wealthy whites took black consorts or concubines. Charles Town attracted a mixture of ethnic and religious groups. French, Scottish, Irish, and Germans migrated to the developing seacoast town, representing numerous Protestant denominations. Because of the battles between English "royalty" and the Roman Catholic Church, practicing Catholics were not allowed to settle in South Carolina until after the American Revolution. Jews were allowed, and Sephardic Jews migrated to the city in such numbers that by the beginning of the 19th century, the city was home to the largest and wealthiest Jewish community in North America—a status it held until about 1830.

On 26 June 1950, the National Assembly supported a crucial bill written by Milovan Đilas and Tito about "self-management" (samoupravljanje): a type of cooperative independent socialist experiment that introduced profit sharing and workplace democracy in previously state-run enterprises which then became the direct social ownership of the employees. On 13 January 1953, they established that the law on self-management was the basis of the entire social order in Yugoslavia. Tito also succeeded Ivan Ribar as the President of Yugoslavia on 14 January 1953. After Stalin's death Tito rejected the USSR's invitation for a visit to discuss normalization of relations between two nations. Nikita Khrushchev and Nikolai Bulganin visited Tito in Belgrade in 1955 and apologized for wrongdoings by Stalin's administration. Tito visited the USSR in 1956, which signaled to the world that animosity between Yugoslavia and USSR was easing. However, the relationship between the USSR and Yugoslavia would reach another low in the late 1960s. Commenting on the crisis, Tito concluded that:

Neptune's weather is characterised by extremely dynamic storm systems, with winds reaching speeds of almost 600 m/s (2,200 km/h; 1,300 mph)—nearly reaching supersonic flow. More typically, by tracking the motion of persistent clouds, wind speeds have been shown to vary from 20 m/s in the easterly direction to 325 m/s westward. At the cloud tops, the prevailing winds range in speed from 400 m/s along the equator to 250 m/s at the poles. Most of the winds on Neptune move in a direction opposite the planet's rotation. The general pattern of winds showed prograde rotation at high latitudes vs. retrograde rotation at lower latitudes. The difference in flow direction is thought to be a "skin effect" and not due to any deeper atmospheric processes. At 70° S latitude, a high-speed jet travels at a speed of 300 m/s.

He attained a perfect score on the graduate school entrance exams to Princeton University in mathematics and physics—an unprecedented feat—but did rather poorly on the history and English portions. Attendees at Feynman's first seminar included Albert Einstein, Wolfgang Pauli, and John von Neumann. He received a PhD from Princeton in 1942; his thesis advisor was John Archibald Wheeler. Feynman's thesis applied the principle of stationary action to problems of quantum mechanics, inspired by a desire to quantize the Wheeler–Feynman absorber theory of electrodynamics, laying the groundwork for the "path integral" approach and Feynman diagrams, and was titled "The Principle of Least Action in Quantum Mechanics".

Yale's residential college system was established in 1933 by Edward S. Harkness, who admired the social intimacy of Oxford and Cambridge and donated significant funds to found similar colleges at Yale and Harvard. Though Yale's colleges resemble their English precursors organizationally and architecturally, they are dependent entities of Yale College and have limited autonomy. The colleges are led by a master and an academic dean, who reside in the college, and university faculty and affiliates comprise each college's fellowship. Colleges offer their own seminars, social events, and speaking engagements known as "Master's Teas," but do not contain programs of study or academic departments. Instead, all undergraduate courses are taught by the Faculty of Arts and Sciences and are open to members of any college.

These critics of the modern separation of church and state also note the official establishment of religion in several of the states at the time of ratification, to suggest that the modern incorporation of the Establishment Clause as to state governments goes against the original constitutional intent.[citation needed] The issue is complex, however, as the incorporation ultimately bases on the passage of the 14th Amendment in 1868, at which point the first amendment's application to the state government was recognized. Many of these constitutional debates relate to the competing interpretive theories of originalism versus modern, progressivist theories such as the doctrine of the Living Constitution. Other debates center on the principle of the law of the land in America being defined not just by the Constitution's Supremacy Clause, but also by legal precedence, making an accurate reading of the Constitution subject to the mores and values of a given era, and rendering the concept of historical revisionism irrelevant when discussing the Constitution.

Although the Adventist churches hold much in common, their theologies differ on whether the intermediate state is unconscious sleep or consciousness, whether the ultimate punishment of the wicked is annihilation or eternal torment, the nature of immortality, whether or not the wicked are resurrected after the millennium, and whether the sanctuary of Daniel 8 refers to the one in heaven or one on earth. The movement has encouraged the examination of the whole Bible, leading Seventh-day Adventists and some smaller Adventist groups to observe the Sabbath. The General Conference of Seventh-day Adventists has compiled that church's core beliefs in the 28 Fundamental Beliefs (1980 and 2005), which use Biblical references as justification.

Following the German unconditional surrender, Eisenhower was appointed Military Governor of the U.S. Occupation Zone, based at the IG Farben Building in Frankfurt am Main. He had no responsibility for the other three zones, controlled by Britain, France and the Soviet Union, except for the city of Berlin, which was managed by the Four-Power Authorities through the Allied Kommandatura as the governing body. Upon discovery of the Nazi concentration camps, he ordered camera crews to document evidence of the atrocities in them for use in the Nuremberg Trials. He reclassified German prisoners of war (POWs) in U.S. custody as Disarmed Enemy Forces (DEFs), who were no longer subject to the Geneva Convention. Eisenhower followed the orders laid down by the Joint Chiefs of Staff (JCS) in directive JCS 1067, but softened them by bringing in 400,000 tons of food for civilians and allowing more fraternization. In response to the devastation in Germany, including food shortages and an influx of refugees, he arranged distribution of American food and medical equipment. His actions reflected the new American attitudes of the German people as Nazi victims not villains, while aggressively purging the ex-Nazis.
