The Americo-Liberian settlers did not identify with the indigenous peoples they encountered, especially those in communities of the more isolated "bush." They knew nothing of their cultures, languages or animist religion. Encounters with tribal Africans in the bush often developed as violent confrontations. The colonial settlements were raided by the Kru and Grebo people from their inland chiefdoms. Because of feeling set apart and superior by their culture and education to the indigenous peoples, the Americo-Liberians developed as a small elite that held on to political power. It excluded the indigenous tribesmen from birthright citizenship in their own lands until 1904, in a repetition of the United States' treatment of Native Americans. Because of the cultural gap between the groups and assumption of superiority of western culture, the Americo-Liberians envisioned creating a western-style state to which the tribesmen should assimilate. They encouraged religious organizations to set up missions and schools to educate the indigenous peoples.

The city struck fortune in the late 18th century with the inventions and industrial activity of Eli Whitney, a Yale graduate who remained in New Haven to develop the cotton gin and establish a gun-manufacturing factory in the northern part of the city near the Hamden town line. That area is still known as Whitneyville, and the main road through both towns is known as Whitney Avenue. The factory is now the Eli Whitney Museum, which has a particular emphasis on activities for children and exhibits pertaining to the A. C. Gilbert Company. His factory, along with that of Simeon North, and the lively clock-making and brass hardware sectors, contributed to making early Connecticut a powerful manufacturing economy; so many arms manufacturers sprang up that the state became known as "The Arsenal of America". It was in Whitney's gun-manufacturing plant that Samuel Colt invented the automatic revolver in 1836. The Farmington Canal, created in the early 19th century, was a short-lived transporter of goods into the interior regions of Connecticut and Massachusetts, and ran from New Haven to Northampton, Massachusetts.

A P-N junction can convert absorbed light energy into a proportional electric current. The same process is reversed here (i.e. the P-N junction emits light when electrical energy is applied to it). This phenomenon is generally called electroluminescence, which can be defined as the emission of light from a semi-conductor under the influence of an electric field. The charge carriers recombine in a forward-biased P-N junction as the electrons cross from the N-region and recombine with the holes existing in the P-region. Free electrons are in the conduction band of energy levels, while holes are in the valence energy band. Thus the energy level of the holes will be lesser than the energy levels of the electrons. Some portion of the energy must be dissipated in order to recombine the electrons and the holes. This energy is emitted in the form of heat and light.

Question: What is the phenomenon where a P-N junction emits light when an electrical current is applied to it?
Answer: electroluminescence.

A defect in the human homologue of the Drosophila "period" gene was identified as a cause of the sleep disorder FASPS (Familial advanced sleep phase syndrome), underscoring the conserved nature of the molecular circadian clock through evolution. Many more genetic components of the biological clock are now known. Their interactions result in an interlocked feedback loop of gene products resulting in periodic fluctuations that the cells of the body interpret as a specific time of the day.[citation needed]

Whereas most Christians believe the gibbet on which Jesus was executed was the traditional two-beamed cross, the Jehovah's Witnesses hold the view that a single upright stake was used. The Greek and Latin words used in the earliest Christian writings are ambiguous. The Koine Greek terms used in the New Testament are stauros (σταυρός) and xylon (ξύλον). The latter means wood (a live tree, timber or an object constructed of wood); in earlier forms of Greek, the former term meant an upright stake or pole, but in Koine Greek it was used also to mean a cross. The Latin word crux was also applied to objects other than a cross.

In 14th-century England, hound (from Old English: hund) was the general word for all domestic canines, and dog referred to a subtype of hound, a group including the mastiff. It is believed this "dog" type was so common, it eventually became the prototype of the category "hound". By the 16th century, dog had become the general word, and hound had begun to refer only to types used for hunting. The word "hound" is ultimately derived from the Proto-Indo-European word *kwon- "dog".

In 1790, the first federal population census was taken in the United States. Enumerators were instructed to classify free residents as white or "other." Only the heads of households were identified by name in the federal census until 1850. Native Americans were included among "Other;" in later censuses, they were included as "Free people of color" if they were not living on Indian reservations. Slaves were counted separately from free persons in all the censuses until the Civil War and end of slavery. In later censuses, people of African descent were classified by appearance as mulatto (which recognized visible European ancestry in addition to African) or black.

At the end of the 16th century, England and the Netherlands began to challenge Portugal's monopoly of trade with Asia, forming private joint-stock companies to finance the voyages—the English, later British, East India Company and the Dutch East India Company, chartered in 1600 and 1602 respectively. The primary aim of these companies was to tap into the lucrative spice trade, an effort focused mainly on two regions; the East Indies archipelago, and an important hub in the trade network, India. There, they competed for trade supremacy with Portugal and with each other. Although England ultimately eclipsed the Netherlands as a colonial power, in the short term the Netherlands' more advanced financial system and the three Anglo-Dutch Wars of the 17th century left it with a stronger position in Asia. Hostilities ceased after the Glorious Revolution of 1688 when the Dutch William of Orange ascended the English throne, bringing peace between the Netherlands and England. A deal between the two nations left the spice trade of the East Indies archipelago to the Netherlands and the textiles industry of India to England, but textiles soon overtook spices in terms of profitability, and by 1720, in terms of sales, the British company had overtaken the Dutch.

Liber Aboali Abincine de Anima in arte Alchemiae was the most influential, having influenced later medieval chemists and alchemists such as Vincent of Beauvais. However Anawati argues (following Ruska) that the de Anima is a fake by a Spanish author. Similarly the Declaratio is believed not to be actually by Avicenna. The third work (The Book of Minerals) is agreed to be Avicenna's writing, adapted from the Kitab al-Shifa (Book of the Remedy). Ibn Sina classified minerals into stones, fusible substances, sulfurs, and salts, building on the ideas of Aristotle and Jabir. The epistola de Re recta is somewhat less sceptical of alchemy; Anawati argues that it is by Avicenna, but written earlier in his career when he had not yet firmly decided that transmutation was impossible.

Mithridates the Great was the ruler of Pontus, a large kingdom in Asia Minor (modern Turkey), from 120 to 63 BC. Mithridates antagonised Rome by seeking to expand his kingdom, and Rome for her part seemed equally eager for war and the spoils and prestige that it might bring. In 88 BC, Mithridates ordered the killing of a majority of the 80,000 Romans living in his kingdom. The massacre was the official reason given for the commencement of hostilities in the First Mithridatic War. The Roman general Lucius Cornelius Sulla forced Mithridates out of Greece proper, but then had to return to Italy to answer the internal threat posed by his rival, Gaius Marius. A peace was made between Rome and Pontus, but this proved only a temporary lull.

Oda Nobunaga made innovations in the fields of organization and war tactics, heavily used arquebuses, developed commerce and industry and treasured innovation. Consecutive victories enabled him to realize the termination of the Ashikaga Bakufu and the disarmament of the military powers of the Buddhist monks, which had inflamed futile struggles among the populace for centuries. Attacking from the "sanctuary" of Buddhist temples, they were constant headaches to any warlord and even the Emperor who tried to control their actions. He died in 1582 when one of his generals, Akechi Mitsuhide, turned upon him with his army.

Racial discrimination continued to be enacted in new laws in the 20th century, for instance the one-drop rule was enacted in Virginia's 1924 Racial Integrity Law and in other southern states, in part influenced by the popularity of eugenics and ideas of racial purity. People buried fading memories that many whites had multiracial ancestry. Many families were multiracial. Similar laws had been proposed but not passed in the late nineteenth century in South Carolina and Virginia, for instance. After regaining political power in Southern states by disenfranchising blacks, white Democrats passed laws to impose Jim Crow and racial segregation to restore white supremacy. They maintained these until forced to change in the 1960s and after by enforcement of federal legislation authorizing oversight of practices to protect the constitutional rights of African Americans and other minority citizens.

Though there is no doubt that the demographic crisis of the 14th century caused a dramatic fall in production and commerce in absolute terms, there has been a vigorous historical debate over whether the decline was greater than the fall in population. While the older orthodoxy held that the artistic output of the Renaissance was a result of greater opulence, more recent studies have suggested that there might have been a so-called 'depression of the Renaissance'. In spite of convincing arguments for the case, the statistical evidence is simply too incomplete for a definite conclusion to be made.

Post-punk is a heterogeneous type of rock music that emerged in the wake of the punk movement of the 1970s. Drawing inspiration from elements of punk rock while departing from its musical conventions and wider cultural affiliations, post-punk music was marked by varied, experimentalist sensibilities and its "conceptual assault" on rock tradition. Artists embraced electronic music, black dance styles and the avant-garde, as well as novel recording technology and production techniques. The movement also saw the frequent intersection of music with art and politics, as artists liberally drew on sources such as critical theory, cinema, performance art and modernist literature. Accompanying these musical developments were subcultures that produced visual art, multimedia performances, independent record labels and fanzines in conjunction with the music.

Under the 1995–2004 National Hockey League collective bargaining agreement, teams were limited to nine preseason games. From 1975 to 1991, NHL teams sometimes played exhibition games against teams from the Soviet Union in the Super Series, and in 1978, played against World Hockey Association teams also in preseason training. Like the NFL, the NHL sometimes schedules exhibition games for cities without their own NHL teams, often at a club's minor league affiliate (e.g. Carolina Hurricanes games at Time Warner Cable Arena in Charlotte, home of their AHL affiliate; Los Angeles Kings games at Citizens Business Bank Arena in Ontario, California, home of their ECHL affiliate; Montreal Canadiens games at Colisée Pepsi in Quebec City, which has no pro hockey but used to have an NHL team until 1995; Washington Capitals at 1st Mariner Arena in the Baltimore Hockey Classic; various Western Canada teams at Credit Union Centre in Saskatoon, a potential NHL expansion venue). Since the 2000s, some preseason games have been played in Europe against European teams, as part of the NHL Challenge and NHL Premiere series. In addition to the standard preseason, there also exist prospect tournaments such as the Vancouver Canucks' YoungStars tournament and the Detroit Red Wings' training camp, in which NHL teams' younger prospects face off against each other under their parent club's banner.

By 1640, the town's theocratic government and nine-square grid plan were in place, and the town was renamed Newhaven from Quinnipiac. However, the area north of New Haven remained Quinnipiac until 1678, when it was renamed Hamden. The settlement became the headquarters of the New Haven Colony. At the time, the New Haven Colony was separate from the Connecticut Colony, which had been established to the north centering on Hartford. One of the principal differences between the two colonies was that the New Haven colony was an intolerant theocracy that did not permit other churches to be established, while the Connecticut colony permitted the establishment of other churches.

Defining exactly what section of a DNA sequence comprises a gene is difficult. Regulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity. Similarly, a gene's introns can be much larger than its exons. Regulatory regions can even be on entirely different chromosomes and operate in trans to allow regulatory regions on one chromosome to come in contact with target genes on another chromosome.

Question: How do regulatory regions on different chromosomes operate in order to allow regions on different chromosomes to come into contact with one another?
Answer: in trans.

In 1902, the Siemens company developed a tantalum lamp filament. These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports. The metal filament had the property of gradually shortening in use; the filaments were installed with large loops that tightened in use. This made lamps in use for several hundred hours quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913.

Question: What were the major advantages of the tantalum light filament?
Answer: These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures..

Infrared vibrational spectroscopy (see also near-infrared spectroscopy) is a technique that can be used to identify molecules by analysis of their constituent bonds. Each chemical bond in a molecule vibrates at a frequency characteristic of that bond. A group of atoms in a molecule (e.g., CH2) may have multiple modes of oscillation caused by the stretching and bending motions of the group as a whole. If an oscillation leads to a change in dipole in the molecule then it will absorb a photon that has the same frequency. The vibrational frequencies of most molecules correspond to the frequencies of infrared light. Typically, the technique is used to study organic compounds using light radiation from 4000–400 cm−1, the mid-infrared. A spectrum of all the frequencies of absorption in a sample is recorded. This can be used to gain information about the sample composition in terms of chemical groups present and also its purity (for example, a wet sample will show a broad O-H absorption around 3200 cm−1).

Question: What do the vibrational frequencies of molecules usually correspond to?
Answer: the frequencies of infrared light.
