Stepper motors can be rotated to a specific angle in discrete steps with ease, and hence stepper motors are used for read/write head positioning in computer floppy diskette drives. They were used for the same purpose in pre-gigabyte era computer disk drives, where the precision and speed they offered was adequate for the correct positioning of the read/write head of a hard disk drive. As drive density increased, the precision and speed limitations of stepper motors made them obsolete for hard drives—the precision limitation made them unusable, and the speed limitation made them uncompetitive—thus newer hard disk drives use voice coil-based head actuator systems. (The term "voice coil" in this connection is historic; it refers to the structure in a typical (cone type) loudspeaker. This structure was used for a while to position the heads. Modern drives have a pivoted coil mount; the coil swings back and forth, something like a blade of a rotating fan. Nevertheless, like a voice coil, modern actuator coil conductors (the magnet wire) move perpendicular to the magnetic lines of force.)

In Mark 15:25 crucifixion takes place at the third hour (9 a.m.) and Jesus' death at the ninth hour (3 p.m.). However, in John 19:14 Jesus is still before Pilate at the sixth hour. Scholars have presented a number of arguments to deal with the issue, some suggesting a reconciliation, e.g., based on the use of Roman timekeeping in John but not in Mark, yet others have rejected the arguments. Several notable scholars have argued that the modern precision of marking the time of day should not be read back into the gospel accounts, written at a time when no standardization of timepieces, or exact recording of hours and minutes was available, and time was often approximated to the closest three-hour period.

Question: What is another reason the times differ so much?
Answer: no standardization of timepieces, or exact recording of hours and minutes was available.

There are technical limitations to archiving a web site, and as a consequence, it is possible for opposing parties in litigation to misuse the results provided by web site archives. This problem can be exacerbated by the practice of submitting screen shots of web pages in complaints, answers, or expert witness reports, when the underlying links are not exposed and therefore, can contain errors. For example, archives such as the Wayback Machine do not fill out forms and therefore, do not include the contents of non-RESTful e-commerce databases in their archives.

Question: What kind of sites contain information that the Wayback Machine does not record?
Answer: e-commerce.

Municipalities (Gemeinden): Every rural district and every Amt is subdivided into municipalities, while every urban district is a municipality in its own right. There are (as of 6 March 2009[update]) 12,141 municipalities, which are the smallest administrative units in Germany. Cities and towns are municipalities as well, also having city rights or town rights (Stadtrechte). Nowadays, this is mostly just the right to be called a city or town. However, in former times there were many other privileges, including the right to impose local taxes or to allow industry only within city limits.

Scholars argue that Lee's approach to class and race was more complex "than ascribing racial prejudice primarily to 'poor white trash' ... Lee demonstrates how issues of gender and class intensify prejudice, silence the voices that might challenge the existing order, and greatly complicate many Americans' conception of the causes of racism and segregation." Lee's use of the middle-class narrative voice is a literary device that allows an intimacy with the reader, regardless of class or cultural background, and fosters a sense of nostalgia. Sharing Scout and Jem's perspective, the reader is allowed to engage in relationships with the conservative antebellum Mrs. Dubose; the lower-class Ewells, and the Cunninghams who are equally poor but behave in vastly different ways; the wealthy but ostracized Mr. Dolphus Raymond; and Calpurnia and other members of the black community. The children internalize Atticus' admonition not to judge someone until they have walked around in that person's skin, gaining a greater understanding of people's motives and behavior.

Over 50% of undergraduate students live on campus. Most of the residence halls on campus are located on the South 40, named because of its adjacent location on the south side of the Danforth Campus and its size of 40 acres (160,000 m2). It is the location of all the freshman buildings as well as several upperclassman buildings, which are set up in the traditional residential college system. All of the residential halls are co-ed. The South 40 is organized as a pedestrian-friendly environment wherein residences surround a central recreational lawn known as the Swamp. Bear's Den (the largest dining hall on campus), the Habif Health and Wellness Center (Student Health Services), the Residential Life Office, University Police Headquarters, various student-owned businesses (e.g. the laundry service, Wash U Wash), and the baseball, softball, and intramural fields are also located on the South 40.

Enlisted members of the USAF have pay grades from E-1 (entry level) to E-9 (senior enlisted). While all USAF military personnel are referred to as Airmen, the term also refers to the pay grades of E-1 through E-4, which are below the level of non-commissioned officers (NCOs). Above the pay grade of E-4 (i.e., pay grades E-5 through E-9) all ranks fall into the category of NCO and are further subdivided into "NCOs" (pay grades E-5 and E-6) and "Senior NCOs" (pay grades E-7 through E-9); the term "Junior NCO" is sometimes used to refer to staff sergeants and technical sergeants (pay grades E-5 and E-6).

Mutations or deletions of clock gene in mice have demonstrated the importance of body clocks to ensure the proper timing of cellular/metabolic events; clock-mutant mice are hyperphagic and obese, and have altered glucose metabolism. In mice, deletion of the Rev-ErbA alpha clock gene facilitates diet-induced obesity and changes the balance between glucose and lipid utilization predisposing to diabetes. However, it is not clear whether there is a strong association between clock gene polymorphisms in humans and the susceptibility to develop the metabolic syndrome.

Question: What do mice without the clock gene become?
Answer: hyperphagic and obese.

In 1890 Robert Louis Stevenson, his wife Fanny Vandegrift Stevenson and her son Lloyd Osbourne sailed on the Janet Nicoll, a trading steamer owned by Henderson and Macfarlane of Auckland, New Zealand, which operated between Sydney and Auckland and into the central Pacific. The Janet Nicoll visited three of the Ellice Islands; while Fanny records that they made landfall at Funafuti, Niutao and Nanumea, Jane Resture suggests that it was more likely they landed at Nukufetau rather than Funafuti. An account of this voyage was written by Fanny Stevenson and published under the title The Cruise of the Janet Nichol, together with photographs taken by Robert Louis Stevenson and Lloyd Osbourne.

Historically, the name Armenian has come to internationally designate this group of people. It was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu (in Babylonian) as Armina (in Old Persian; Armina (    ) and Harminuya (in Elamite). In Greek, Αρμένιοι "Armenians" is attested from about the same time, perhaps the earliest reference being a fragment attributed to Hecataeus of Miletus (476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians.

Very few early Byzantine mosaics survived the Iconoclastic destruction of the 8th century. Among the rare examples are the 6th-century Christ in majesty (or Ezekiel's Vision) mosaic in the apse of the Church of Hosios David in Thessaloniki that was hidden behind mortar during those dangerous times. Nine mosaic panels in the Hagios Demetrios Church, which were made between 634 and 730, also escaped destruction. Unusually almost all represent Saint Demetrius of Thessaloniki, often with suppliants before him.

The arts of Southeast Asia have affinity with the arts of other areas. Dance in much of Southeast Asia includes movement of the hands as well as the feet, to express the dance's emotion and meaning of the story that the ballerina is going to tell the audience. Most of Southeast Asia introduced dance into their court; in particular, Cambodian royal ballet represented them in the early 7th century before the Khmer Empire, which was highly influenced by Indian Hinduism. Apsara Dance, famous for strong hand and feet movement, is a great example of Hindu symbolic dance.

In an effort to demonstrate peaceful intentions toward Germany, on 13 April 1941, the Soviets signed a neutrality pact with Axis power Japan. While Stalin had little faith in Japan's commitment to neutrality, he felt that the pact was important for its political symbolism, to reinforce a public affection for Germany. Stalin felt that there was a growing split in German circles about whether Germany should initiate a war with the Soviet Union. Stalin did not know that Hitler had been secretly discussing an invasion of the Soviet Union since summer 1940, and that Hitler had ordered his military in late 1940 to prepare for war in the east regardless of the parties' talks of a potential Soviet entry as a fourth Axis Power.

The Democrats gained a majority in both houses in the 1954 election. Eisenhower had to work with the Democratic Majority Leader Lyndon B. Johnson (later U.S. president) in the Senate and Speaker Sam Rayburn in the House, both from Texas. Joe Martin, the Republican Speaker from 1947 to 1949 and again from 1953 to 1955, wrote that Eisenhower "never surrounded himself with assistants who could solve political problems with professional skill. There were exceptions, Leonard W. Hall, for example, who as chairman of the Republican National Committee tried to open the administration's eyes to the political facts of life, with occasional success. However, these exceptions were not enough to right the balance."

Prodigies were transgressions in the natural, predictable order of the cosmos – signs of divine anger that portended conflict and misfortune. The Senate decided whether a reported prodigy was false, or genuine and in the public interest, in which case it was referred to the public priests, augurs and haruspices for ritual expiation. In 207 BC, during one of the Punic Wars' worst crises, the Senate dealt with an unprecedented number of confirmed prodigies whose expiation would have involved "at least twenty days" of dedicated rites.

Question: Of what were prodigies predictors?
Answer: conflict and misfortune.

After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.

The Alaska Permanent Fund is a constitutionally authorized appropriation of oil revenues, established by voters in 1976 to manage a surplus in state petroleum revenues from oil, largely in anticipation of the recently constructed Trans-Alaska Pipeline System. The fund was originally proposed by Governor Keith Miller on the eve of the 1969 Prudhoe Bay lease sale, out of fear that the legislature would spend the entire proceeds of the sale (which amounted to $900 million) at once. It was later championed by Governor Jay Hammond and Kenai state representative Hugh Malone. It has served as an attractive political prospect ever since, diverting revenues which would normally be deposited into the general fund.

A week after the implementation of the no-fly zone, NATO announced that it would be enforced. On 30 April a NATO airstrike killed Gaddafi's sixth son and three of his grandsons in Tripoli, though Gaddafi and his wife were unharmed. Western officials remained divided over whether Gaddafi was a legitimate military target under the U.N. Security Council resolution. U.S. Secretary of Defense Robert Gates said that NATO was "not targeting Gaddafi specifically" but that his command-and-control facilities were legitimate targets—including a facility inside his sprawling Tripoli compound that was hit with airstrikes on 25 April.

The United States has become essentially a two-party system. Since a conservative (such as the Republican Party) and liberal (such as the Democratic Party) party has usually been the status quo within American politics. The first parties were called Federalist and Republican, followed by a brief period of Republican dominance before a split occurred between National Republicans and Democratic Republicans. The former became the Whig Party and the latter became the Democratic Party. The Whigs survived only for two decades before they split over the spread of slavery, those opposed becoming members of the new Republican Party, as did anti-slavery members of the Democratic Party. Third parties (such as the Libertarian Party) often receive little support and are very rarely the victors in elections. Despite this, there have been several examples of third parties siphoning votes from major parties that were expected to win (such as Theodore Roosevelt in the election of 1912 and George Wallace in the election of 1968). As third party movements have learned, the Electoral College's requirement of a nationally distributed majority makes it difficult for third parties to succeed. Thus, such parties rarely win many electoral votes, although their popular support within a state may tip it toward one party or the other. Wallace had weak support outside the South. More generally, parties with a broad base of support across regions or among economic and other interest groups, have a great chance of winning the necessary plurality in the U.S.'s largely single-member district, winner-take-all elections. The tremendous land area and large population of the country are formidable challenges to political parties with a narrow appeal.

In prokaryotes, transcription occurs in the cytoplasm; for very long transcripts, translation may begin at the 5' end of the RNA while the 3' end is still being transcribed. In eukaryotes, transcription occurs in the nucleus, where the cell's DNA is stored. The RNA molecule produced by the polymerase is known as the primary transcript and undergoes post-transcriptional modifications before being exported to the cytoplasm for translation. One of the modifications performed is the splicing of introns which are sequences in the transcribed region that do not encode protein. Alternative splicing mechanisms can result in mature transcripts from the same gene having different sequences and thus coding for different proteins. This is a major form of regulation in eukaryotic cells and also occurs in some prokaryotes.:7.5

Question: If the transcription is very long, where on the RNA may translation begin?
Answer: at the 5' end of the RNA.
