After Germany led the way with starting DST (German: Sommerzeit) during World War I on 30 April 1916 together with its allies to alleviate hardships from wartime coal shortages and air raid blackouts, the political equation changed in other countries; the United Kingdom used DST first on 21 May 1916. US retailing and manufacturing interests led by Pittsburgh industrialist Robert Garland soon began lobbying for DST, but were opposed by railroads. The US's 1917 entry to the war overcame objections, and DST was established in 1918.

The Han-era family was patrilineal and typically had four to five nuclear family members living in one household. Multiple generations of extended family members did not occupy the same house, unlike families of later dynasties. According to Confucian family norms, various family members were treated with different levels of respect and intimacy. For example, there were different accepted time frames for mourning the death of a father versus a paternal uncle. Arranged marriages were normal, with the father's input on his offspring's spouse being considered more important than the mother's. Monogamous marriages were also normal, although nobles and high officials were wealthy enough to afford and support concubines as additional lovers. Under certain conditions dictated by custom, not law, both men and women were able to divorce their spouses and remarry.

Roman entanglement in the Balkans began when Illyrian piratical raids on Roman merchants led to invasions of Illyria (the First and, Second Illyrian Wars). Tension between Macedon and Rome increased when the young king of Macedon, Philip V harbored one of the chief pirates, Demetrius of Pharos (a former client of Rome). As a result, in an attempt to reduce Roman influence in the Balkans, Philip allied himself with Carthage after Hannibal had dealt the Romans a massive defeat at the Battle of Cannae (216 BC) during the Second Punic War. Forcing the Romans to fight on another front when they were at a nadir of manpower gained Philip the lasting enmity of the Romans; the only real result from the somewhat insubstantial First Macedonian War (215–202 BC).

The remaining animals form a monophyletic group called the Bilateria. For the most part, they are bilaterally symmetric, and often have a specialized head with feeding and sensory organs. The body is triploblastic, i.e. all three germ layers are well-developed, and tissues form distinct organs. The digestive chamber has two openings, a mouth and an anus, and there is also an internal body cavity called a coelom or pseudocoelom. There are exceptions to each of these characteristics, however — for instance adult echinoderms are radially symmetric, and certain parasitic worms have extremely simplified body structures.

As Universal's main product had always been low-budget film, it was one of the last major studios to have a contract with Technicolor. The studio did not make use of the three-strip Technicolor process until Arabian Nights (1942), starring Jon Hall and Maria Montez. The following year, Technicolor was also used in Universal's remake of their 1925 horror melodrama, Phantom of the Opera with Claude Rains and Nelson Eddy. With the success of their first two pictures, a regular schedule of high-budget, Technicolor films followed.

Insectivorous insects, or insects which feed on other insects, are beneficial to humans because they eat insects that could cause damage to agriculture and human structures. For example, aphids feed on crops and cause problems for farmers, but ladybugs feed on aphids, and can be used as a means to get significantly reduce pest aphid populations. While birds are perhaps more visible predators of insects, insects themselves account for the vast majority of insect consumption. Ants also help control animal populations by consuming small vertebrates. Without predators to keep them in check, insects can undergo almost unstoppable population explosions.:328–348:400

Some research suggests that "[f]or some [people] the focus of sexual interest will shift at various points through the life span..." "There... [was, as of 1995,] essentially no research on the longitudinal stability of sexual orientation over the adult life span... It [was]... still an unanswered question whether... [the] measure [of 'the complex components of sexual orientation as differentiated from other aspects of sexual identity at one point in time'] will predict future behavior or orientation. Certainly, it is... not a good predictor of past behavior and self-identity, given the developmental process common to most gay men and lesbians (i.e., denial of homosexual interests and heterosexual experimentation prior to the coming-out process)."

 North Korea: The event was held in Pyongyang on April 28. It was the first time that the Olympic torch has traveled to North Korea. A crowd of thousands waving pink paper flowers and small flags with the Beijing Olympics logo were organized by the authoritarian regime watched the beginning of the relay in Pyongyang, some waving Chinese flags. The event was presided over by the head of the country's parliament, Kim Yong Nam. The North, an ally of China, has been critical of disruptions to the torch relay elsewhere and has supported Beijing in its actions against protests in Tibet. Kim passed the torch to the first runner Pak Du Ik, who played on North Korea's 1966 World Cup soccer team, as he began the 19-kilometre route through Pyongyang. The relay began from the large sculpted flame of the obelisk of the Juche Tower, which commemorates the national ideology of Juche, or "self-reliance", created by the country's late founding President Kim Il Sung, father of leader Kim Jong Il, who did not attend.

His next theatrical release in that same year was the World War II film Saving Private Ryan, about a group of U.S. soldiers led by Capt. Miller (Tom Hanks) sent to bring home a paratrooper whose three older brothers were killed in the same twenty-four hours, June 5–6, of the Normandy landing. The film was a huge box office success, grossing over $481 million worldwide and was the biggest film of the year at the North American box office (worldwide it made second place after Michael Bay's Armageddon). Spielberg won his second Academy Award for his direction. The film's graphic, realistic depiction of combat violence influenced later war films such as Black Hawk Down and Enemy at the Gates. The film was also the first major hit for DreamWorks, which co-produced the film with Paramount Pictures (as such, it was Spielberg's first release from the latter that was not part of the Indiana Jones series). Later, Spielberg and Tom Hanks produced a TV mini-series based on Stephen Ambrose's book Band of Brothers. The ten-part HBO mini-series follows Easy Company of the 101st Airborne Division's 506th Parachute Infantry Regiment. The series won a number of awards at the Golden Globes and the Emmys.

To prevent this problem, in one implementation of destination control, every user gets an RFID card to identify himself, so the system knows every user call and can cancel the first call if the passenger decides to travel to another destination to prevent empty calls. The newest invention knows even where people are located and how many on which floor because of their identification, either for the purposes of evacuating the building or for security reasons. Another way to prevent this issue is to treat everyone travelling from one floor to another as one group and to allocate only one car for that group.

Armenian literature dates back to 400 AD, when Mesrop Mashtots first invented the Armenian alphabet. This period of time is often viewed as the Golden Age of Armenian literature. Early Armenian literature was written by the "father of Armenian history", Moses of Chorene, who authored The History of Armenia. The book covers the time-frame from the formation of the Armenian people to the fifth century AD. The nineteenth century beheld a great literary movement that was to give rise to modern Armenian literature. This period of time, during which Armenian culture flourished, is known as the Revival period (Zartonki sherchan). The Revivalist authors of Constantinople and Tiflis, almost identical to the Romanticists of Europe, were interested in encouraging Armenian nationalism. Most of them adopted the newly created Eastern or Western variants of the Armenian language depending on the targeted audience, and preferred them over classical Armenian (grabar). This period ended after the Hamidian massacres, when Armenians experienced turbulent times. As Armenian history of the 1920s and of the Genocide came to be more openly discussed, writers like Paruyr Sevak, Gevork Emin, Silva Kaputikyan and Hovhannes Shiraz began a new era of literature.

Question: Who came up with the Armenian alphabet?

Federations often have special procedures for amendment of the federal constitution. As well as reflecting the federal structure of the state this may guarantee that the self-governing status of the component states cannot be abolished without their consent. An amendment to the constitution of the United States must be ratified by three-quarters of either the state legislatures, or of constitutional conventions specially elected in each of the states, before it can come into effect. In referendums to amend the constitutions of Australia and Switzerland it is required that a proposal be endorsed not just by an overall majority of the electorate in the nation as a whole, but also by separate majorities in each of a majority of the states or cantons. In Australia, this latter requirement is known as a double majority.

The early Qing military was rooted in the Eight Banners first developed by Nurhaci to organize Jurchen society beyond petty clan affiliations. There were eight banners in all, differentiated by color. The yellow, bordered yellow, and white banners were known as the "Upper Three Banners" and were under the direct command of the emperor. Only Manchus belonging to the Upper Three Banners, and selected Han Chinese who had passed the highest level of martial exams could serve as the emperor's personal bodyguards. The remaining Banners were known as the "Lower Five Banners." They were commanded by hereditary Manchu princes descended from Nurhachi's immediate family, known informally as the "Iron cap princes". Together they formed the ruling council of the Manchu nation as well as high command of the army. Nurhachi's son Hong Taiji expanded the system to include mirrored Mongol and Han Banners. After capturing Beijing in 1644, the relatively small Banner armies were further augmented by the Green Standard Army, made up of those Ming troops who had surrendered to the Qing, which eventually outnumbered Banner troops three to one. They maintained their Ming era organization and were led by a mix of Banner and Green Standard officers.[citation needed]

An urban civilization, the Garamantes, arose around 500 BCE in the heart of the Sahara, in a valley that is now called the Wadi al-Ajal in Fezzan, Libya. The Garamantes achieved this development by digging tunnels far into the mountains flanking the valley to tap fossil water and bring it to their fields. The Garamantes grew populous and strong, conquering their neighbors and capturing many slaves (which were put to work extending the tunnels). The ancient Greeks and the Romans knew of the Garamantes and regarded them as uncivilized nomads. However, they traded with the Garamantes, and a Roman bath has been found in the Garamantes capital of Garama. Archaeologists have found eight major towns and many other important settlements in the Garamantes territory. The Garamantes civilization eventually collapsed after they had depleted available water in the aquifers and could no longer sustain the effort to extend the tunnels further into the mountains.

Question: What was the reason for the collapse of the Garamantes   civilization?
Answer: depleted available water.

In Book 11 of St. Augustine's Confessions, he ruminates on the nature of time, asking, "What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not." He goes on to comment on the difficulty of thinking about time, pointing out the inaccuracy of common speech: "For but few things are there of which we speak properly; of most things we speak improperly, still the things intended are understood."  But Augustine presented the first philosophical argument for the reality of Creation (against Aristotle) in the context of his discussion of time, saying that knowledge of time depends on the knowledge of the movement of things, and therefore time cannot be where there are no creatures to measure its passing (Confessions Book XI ¶30; City of God Book XI ch.6).

In nature, uranium(VI) forms highly soluble carbonate complexes at alkaline pH. This leads to an increase in mobility and availability of uranium to groundwater and soil from nuclear wastes which leads to health hazards. However, it is difficult to precipitate uranium as phosphate in the presence of excess carbonate at alkaline pH. A Sphingomonas sp. strain BSAR-1 has been found to express a high activity alkaline phosphatase (PhoK) that has been applied for bioprecipitation of uranium as uranyl phosphate species from alkaline solutions. The precipitation ability was enhanced by overexpressing PhoK protein in E. coli.

Question: The presence of what substance at alkaline pH makes it difficult to precipitate uranium as phosphate?
Answer: carbonate.

To continue evacuating a chamber indefinitely without requiring infinite growth, a compartment of the vacuum can be repeatedly closed off, exhausted, and expanded again. This is the principle behind positive displacement pumps, like the manual water pump for example. Inside the pump, a mechanism expands a small sealed cavity to create a vacuum. Because of the pressure differential, some fluid from the chamber (or the well, in our example) is pushed into the pump's small cavity. The pump's cavity is then sealed from the chamber, opened to the atmosphere, and squeezed back to a minute size.

---

Question: Why is fluid in a manual pump pushed into the pumps cavity when a small sealed cavity is expanded?
Answer: Because of the pressure differential.

Sometimes overlooked during his life, James Lind, a physician in the British navy, performed the first scientific nutrition experiment in 1747. Lind discovered that lime juice saved sailors that had been at sea for years from scurvy, a deadly and painful bleeding disorder. Between 1500 and 1800, an estimated two million sailors had died of scurvy. The discovery was ignored for forty years, after which British sailors became known as "limeys." The essential vitamin C within citrus fruits would not be identified by scientists until 1932.
