On December 13, 2013, Beyoncé unexpectedly released her eponymous fifth studio album on the iTunes Store without any prior announcement or promotion. The album debuted atop the Billboard 200 chart, giving Beyoncé her fifth consecutive number-one album in the US. This made her the first woman in the chart's history to have her first five studio albums debut at number one. Beyoncé received critical acclaim and commercial success, selling one million digital copies worldwide in six days; The New York Times noted the album's unconventional, unexpected release as significant. Musically an electro-R&B album, it concerns darker themes previously unexplored in her work, such as "bulimia, postnatal depression [and] the fears and insecurities of marriage and motherhood". The single "Drunk in Love", featuring Jay Z, peaked at number two on the Billboard Hot 100 chart. In April 2014, after much speculation in the weeks before, Beyoncé and Jay Z officially announced their On the Run Tour. It served as the couple's first co-headlining stadium tour together. On August 24, 2014, she received the Video Vanguard Award at the 2014 MTV Video Music Awards. Knowles also took home three competitive awards: Best Video with a Social Message and Best Cinematography for "Pretty Hurts", as well as best collaboration for "Drunk in Love". In November, Forbes reported that Beyoncé was the top-earning woman in music for the second year in a row—earning $115 million in the year, more than double her earnings in 2013. Beyoncé was reissued with new material in three forms: as an extended play, a box set, as well as a full platinum edition.

In 1582 the United Provinces invited Francis, Duke of Anjou to lead them; but after a failed attempt to take Antwerp in 1583, the duke left the Netherlands again. After the assassination of William of Orange (10 July 1584), both Henry III of France and Elizabeth I of England declined the offer of sovereignty. However, the latter agreed to turn the United Provinces into a protectorate of England (Treaty of Nonsuch, 1585), and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648.

Callaghan had been widely expected to call a general election in the autumn of 1978 when most opinion polls showed Labour to have a narrow lead. However he decided to extend his wage restraint policy for another year hoping that the economy would be in a better shape for a 1979 election. But during the winter of 1978–79 there were widespread strikes among lorry drivers, railway workers, car workers and local government and hospital workers in favour of higher pay-rises that caused significant disruption to everyday life. These events came to be dubbed the "Winter of Discontent".

Solar cookers use sunlight for cooking, drying and pasteurization. They can be grouped into three broad categories: box cookers, panel cookers and reflector cookers. The simplest solar cooker is the box cooker first built by Horace de Saussure in 1767. A basic box cooker consists of an insulated container with a transparent lid. It can be used effectively with partially overcast skies and will typically reach temperatures of 90–150 °C (194–302 °F). Panel cookers use a reflective panel to direct sunlight onto an insulated container and reach temperatures comparable to box cookers. Reflector cookers use various concentrating geometries (dish, trough, Fresnel mirrors) to focus light on a cooking container. These cookers reach temperatures of 315 °C (599 °F) and above but require direct light to function properly and must be repositioned to track the Sun.

For five consecutive seasons, starting in season seven, the title was given to a white male who plays the guitar – a trend that Idol pundits call the "White guy with guitar" or "WGWG" factor. Just hours before the season eleven finale, where Phillip Phillips was named the winner, Richard Rushfield, author of the book American Idol: The Untold Story, said, "You have this alliance between young girls and grandmas and they see it, not necessarily as a contest to create a pop star competing on the contemporary radio, but as .... who's the nicest guy in a popularity contest," he says, "And that has led to this dynasty of four, and possibly now five, consecutive, affable, very nice, good-looking white boys."

Bronx gang life was depicted in the 1974 novel The Wanderers by Bronx native Richard Price and the 1979 movie of the same name. They are set in the heart of the Bronx, showing apartment life and the then-landmark Krums ice cream parlor. In the 1979 film The Warriors, the eponymous gang go to a meeting in Van Cortlandt Park in the Bronx, and have to fight their way out of the borough and get back to Coney Island in Brooklyn. A Bronx Tale (1993) depicts gang activities in the Belmont "Little Italy" section of the Bronx. The 2005 video game adaptation features levels called Pelham, Tremont, and "Gunhill" (a play off the name Gun Hill Road). This theme lends itself to the title of The Bronx Is Burning, an eight-part ESPN TV mini-series (2007) about the New York Yankees' drive to winning baseball's 1977 World Series. The TV series emphasizes the boisterous nature of the team, led by manager Billy Martin, catcher Thurman Munson and outfielder Reggie Jackson, as well as the malaise of the Bronx and New York City in general during that time, such as the blackout, the city's serious financial woes and near bankruptcy, the arson for insurance payments, and the election of Ed Koch as mayor.

In absolute terms, the planet has lost 52% of its biodiversity since 1970 according to a 2014 study by the World Wildlife Fund. The Living Planet Report 2014 claims that "the number of mammals, birds, reptiles, amphibians and fish across the globe is, on average, about half the size it was 40 years ago". Of that number, 39% accounts for the terrestrial wildlife gone, 39% for the marine wildlife gone, and 76% for the freshwater wildlife gone. Biodiversity took the biggest hit in Latin America, plummeting 83 percent. High-income countries showed a 10% increase in biodiversity, which was canceled out by a loss in low-income countries. This is despite the fact that high-income countries use five times the ecological resources of low-income countries, which was explained as a result of process whereby wealthy nations are outsourcing resource depletion to poorer nations, which are suffering the greatest ecosystem losses.

When Ibn Sina was 22 years old, he lost his father. The Samanid dynasty came to its end in December 1004. Ibn Sina seems to have declined the offers of Mahmud of Ghazni, and proceeded westwards to Urgench in modern Turkmenistan, where the vizier, regarded as a friend of scholars, gave him a small monthly stipend. The pay was small, however, so Ibn Sina wandered from place to place through the districts of Nishapur and Merv to the borders of Khorasan, seeking an opening for his talents. Qabus, the generous ruler of Tabaristan, himself a poet and a scholar, with whom Ibn Sina had expected to find asylum, was on about that date (1012) starved to death by his troops who had revolted. Ibn Sina himself was at this time stricken by a severe illness. Finally, at Gorgan, near the Caspian Sea, Ibn Sina met with a friend, who bought a dwelling near his own house in which Ibn Sina lectured on logic and astronomy. Several of Ibn Sina's treatises were written for this patron; and the commencement of his Canon of Medicine also dates from his stay in Hyrcania.

In addition to limiting the total average power used by the device, the USB specification limits the inrush current (i.e., that used to charge decoupling and filter capacitors) when the device is first connected. Otherwise, connecting a device could cause problems with the host's internal power. USB devices are also required to automatically enter ultra low-power suspend mode when the USB host is suspended. Nevertheless, many USB host interfaces do not cut off the power supply to USB devices when they are suspended.

However, there is significant disagreement within Orthodox Judaism, particularly between Haredi Judaism and Modern Orthodox Judaism, about the extent and circumstances under which the proper application of Halakha should be re-examined as a result of changing realities. As a general rule, Haredi Jews believe that when at all possible the law should be maintained as it was understood by their authorities at the haskalah, believing that it had never changed. Modern Orthodox authorities are more willing to assume that under scrupulous examination, identical principles may lead to different applications in the context of modern life. To the Orthodox Jew, halakha is a guide, God's Law, governing the structure of daily life from the moment he or she wakes up to the moment he goes to sleep. It includes codes of behaviour applicable to a broad range of circumstances (and many hypothetical ones). There are though a number of halakhic meta-principles that guide the halakhic process and in an instance of opposition between a specific halakha and a meta-principle, the meta-principle often wins out . Examples of Halakhic Meta-Principles are: "Deracheha Darchei Noam" - the ways of Torah are pleasant, "Kavod Habriyot" - basic respect for human beings, "Pikuach Nefesh" - the sanctity of human life.

Question: Basic respect for human beings is known as what?

When auto-changing turntables were commonplace, records were typically pressed with a raised (or ridged) outer edge and a raised label area, allowing records to be stacked onto each other without the delicate grooves coming into contact, reducing the risk of damage. Auto-changers included a mechanism to support a stack of several records above the turntable itself, dropping them one at a time onto the active turntable to be played in order. Many longer sound recordings, such as complete operas, were interleaved across several 10-inch or 12-inch discs for use with auto-changing mechanisms, so that the first disk of a three-disk recording would carry sides 1 and 6 of the program, while the second disk would carry sides 2 and 5, and the third, sides 3 and 4, allowing sides 1, 2, and 3 to be played automatically; then the whole stack reversed to play sides 4, 5, and 6.

Katō Kiyomasa was one of the most powerful and well-known lords of the Sengoku Era. He commanded most of Japan's major clans during the invasion of Korea (1592–1598). In a handbook he addressed to "all samurai, regardless of rank" he told his followers that a warrior's only duty in life was to "...grasp the long and the short swords and to die". He also ordered his followers to put forth great effort in studying the military classics, especially those related to loyalty and filial piety. He is best known for his quote: "If a man does not investigate into the matter of Bushido daily, it will be difficult for him to die a brave and manly death. Thus it is essential to engrave this business of the warrior into one's mind well."

Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered around the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age. Until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, Egypt, the Balkans, Cyprus, and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization. The cultural centers of the Greeks have included Athens, Thessalonica, Alexandria, Smyrna, and Constantinople at various periods.

About 10,000 years ago, when the ice melted after the last glacial period, late Paleolithic communities were established along the lake shores and in cave systems. Evidence of human habitation has been found in caves near Vercors, close to Grenoble; in Austria the Mondsee culture shows evidence of houses built on piles to keep them dry. Standing stones have been found in Alpine areas of France and Italy. The rock drawings in Valcamonica are more than 5000 years old; more than 200,000 drawings and etchings have been identified at the site.

Measurement of light or photometry is generally concerned with the amount of useful light falling on a surface and the amount of light emerging from a lamp or other source, along with the colors that can be rendered by this light. The human eye responds differently to light from different parts of the visible spectrum, therefore photometric measurements must take the luminosity function into account when measuring the amount of useful light. The basic SI unit of measurement is the candela (cd), which describes the luminous intensity, all other photometric units are derived from the candela. Luminance for instance is a measure of the density of luminous intensity in a given direction. It describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m2). The CGS unit of luminance is the stilb, which is equal to one candela per square centimetre or 10 kcd/m2. The amount of useful light emitted from a source or the luminous flux is measured in lumen (lm).

Question: What is the CGS unit of lumiance?
Answer: stilb.

Two controversies during the campaign tested him and his staff, but did not affect the campaign. One involved a report that Nixon had improperly received funds from a secret trust. Nixon spoke out adroitly to avoid potential damage, but the matter permanently alienated the two candidates. The second issue centered on Eisenhower's relented decision to confront the controversial methods of Joseph McCarthy on his home turf in a Wisconsin appearance. Just two weeks prior to the election, Eisenhower vowed to go to Korea and end the war there. He promised to maintain a strong commitment against Communism while avoiding the topic of NATO; finally, he stressed a corruption-free, frugal administration at home.

Serious American students of theology and divinity, particularly in New England, regarded Hebrew as a classical language, along with Greek and Latin, and essential for study of the Old Testament in the original words. The Reverend Ezra Stiles, president of the College from 1778 to 1795, brought with him his interest in the Hebrew language as a vehicle for studying ancient Biblical texts in their original language (as was common in other schools), requiring all freshmen to study Hebrew (in contrast to Harvard, where only upperclassmen were required to study the language) and is responsible for the Hebrew phrase אורים ותמים (Urim and Thummim) on the Yale seal. Stiles' greatest challenge occurred in July 1779 when hostile British forces occupied New Haven and threatened to raze the College. However, Yale graduate Edmund Fanning, Secretary to the British General in command of the occupation, interceded and the College was saved. Fanning later was granted an honorary degree LL.D., at 1803, for his efforts.

The Twelve Tables forbade any harmful incantation (malum carmen, or 'noisome metrical charm'); this included the "charming of crops from one field to another" (excantatio frugum) and any rite that sought harm or death to others. Chthonic deities functioned at the margins of Rome's divine and human communities; although sometimes the recipients of public rites, these were conducted outside the sacred boundary of the pomerium. Individuals seeking their aid did so away from the public gaze, during the hours of darkness. Burial grounds and isolated crossroads were among the likely portals. The barrier between private religious practices and "magic" is permeable, and Ovid gives a vivid account of rites at the fringes of the public Feralia festival that are indistinguishable from magic: an old woman squats among a circle of younger women, sews up a fish-head, smears it with pitch, then pierces and roasts it to "bind hostile tongues to silence". By this she invokes Tacita, the "Silent One" of the underworld.
