Incubation, which optimises temperature for chick development, usually begins after the last egg has been laid. In monogamous species incubation duties are often shared, whereas in polygamous species one parent is wholly responsible for incubation. Warmth from parents passes to the eggs through brood patches, areas of bare skin on the abdomen or breast of the incubating birds. Incubation can be an energetically demanding process; adult albatrosses, for instance, lose as much as 83 grams (2.9 oz) of body weight per day of incubation. The warmth for the incubation of the eggs of megapodes comes from the sun, decaying vegetation or volcanic sources. Incubation periods range from 10 days (in woodpeckers, cuckoos and passerine birds) to over 80 days (in albatrosses and kiwis).

Barça beat Athletic Bilbao 4–1 in the 2009 Copa del Rey Final, winning the competition for a record-breaking 25th time. A historic 2–6 victory against Real Madrid followed three days later and ensured that Barcelona became La Liga champions for the 2008–09 season. Barça finished the season by beating the previous year's Champions League winners Manchester United 2–0 at the Stadio Olimpico in Rome to win their third Champions League title and completed the first ever treble won by a Spanish team. The team went on to win the 2009 Supercopa de España against Athletic Bilbao and the 2009 UEFA Super Cup against Shakhtar Donetsk, becoming the first European club to win both domestic and European Super Cups following a treble. In December 2009, Barcelona won the 2009 FIFA Club World Cup, and became the first football club ever to accomplish the sextuple. Barcelona accomplished two new records in Spanish football in 2010 as they retained the La Liga trophy with 99 points and won the Spanish Super Cup trophy for a ninth time.

Estonia produces about 75% of its consumed electricity. In 2011 about 85% of it was generated with locally mined oil shale. Alternative energy sources such as wood, peat, and biomass make up approximately 9% of primary energy production. Renewable wind energy was about 6% of total consumption in 2009. Estonia imports petroleum products from western Europe and Russia. Oil shale energy, telecommunications, textiles, chemical products, banking, services, food and fishing, timber, shipbuilding, electronics, and transportation are key sectors of the economy. The ice-free port of Muuga, near Tallinn, is a modern facility featuring good transshipment capability, a high-capacity grain elevator, chill/frozen storage, and new oil tanker off-loading capabilities.[citation needed] The railroad serves as a conduit between the West, Russia, and other points to the East.[citation needed]

A number of novel ideas about religion developed with the Enlightenment, including Deism and talk of atheism. Deism, according to Thomas Paine, is the simple belief in God the Creator, with no reference to the Bible or any other miraculous source. Instead, the Deist relies solely on personal reason to guide his creed, which was eminently agreeable to many thinkers of the time. Atheism was much discussed, but there were few proponents. Wilson and Reill note that, "In fact, very few enlightened intellectuals, even when they were vocal critics of Christianity, were true atheists. Rather, they were critics of orthodox belief, wedded rather to skepticism, deism, vitalism, or perhaps pantheism." Some followed Pierre Bayle and argued that atheists could indeed be moral men. Many others like Voltaire held that without belief in a God who punishes evil, the moral order of society was undermined. That is, since atheists gave themselves to no Supreme Authority and no law, and had no fear of eternal consequences, they were far more likely to disrupt society. Bayle (1647–1706) observed that in his day, "prudent persons will always maintain an appearance of [religion].". He believed that even atheists could hold concepts of honor and go beyond their own self-interest to create and interact in society. Locke said that if there were no God and no divine law, the result would be moral anarchy: every individual "could have no law but his own will, no end but himself. He would be a god to himself, and the satisfaction of his own will the sole measure and end of all his actions".

Until roughly the 16th century, speakers of all the varieties of the West Germanic languages from the mouth of the Rhine to the Alps had been accustomed to refer to their native speech as Dietsch, (Neder)duyts or some other cognate of theudisk. This let inevitably to confusion since similar terms referred to different languages. Therefore, in the 16th century, a differentiation took place. Owing to Dutch commercial and colonial rivalry in the 16th and 17th centuries, the English term came to refer exclusively to the Dutch. A notable exception is Pennsylvania Dutch, which is a West Central German variety called Deitsch by its speakers. Jersey Dutch, on the other hand, as spoken until the 1950s in New Jersey, is a Dutch-based creole.

The UK political system, while technically a multi-party system, has functioned generally as a two-party (sometimes called a "two-and-a-half party") system; since the 1920s the two largest political parties have been the Conservative Party and the Labour Party. Before the Labour Party rose in British politics the Liberal Party was the other major political party along with the Conservatives. Though coalition and minority governments have been an occasional feature of parliamentary politics, the first-past-the-post electoral system used for general elections tends to maintain the dominance of these two parties, though each has in the past century relied upon a third party to deliver a working majority in Parliament. (A plurality voting system usually leads to a two-party system, a relationship described by Maurice Duverger and known as Duverger's Law.) There are also numerous other parties that hold or have held a number of seats in Parliament.

Financial problems and a reduction in tourism led to Norfolk Island's administration appealing to the Australian federal government for assistance in 2010. In return, the islanders were to pay income tax for the first time but would be eligible for greater welfare benefits. However, by May 2013 agreement had not been reached and islanders were having to leave to find work and welfare. An agreement was finally signed in Canberra on 12 March 2015 to replace self-government with a local council but against the wishes of the Norfolk Island government. A majority of Norfolk Islanders have objected to the Australian plan to make changes to Norfolk Island without first consulting them and allowing their say with 68% of voters against forced changes.

Most modern air defence systems are fairly mobile. Even the larger systems tend to be mounted on trailers and are designed to be fairly quickly broken down or set up. In the past, this was not always the case. Early missile systems were cumbersome and required much infrastructure; many could not be moved at all. With the diversification of air defence there has been much more emphasis on mobility. Most modern systems are usually either self-propelled (i.e. guns or missiles are mounted on a truck or tracked chassis) or easily towed. Even systems that consist of many components (transporter/erector/launchers, radars, command posts etc.) benefit from being mounted on a fleet of vehicles. In general, a fixed system can be identified, attacked and destroyed whereas a mobile system can show up in places where it is not expected. Soviet systems especially concentrate on mobility, after the lessons learnt in the Vietnam war between the USA and Vietnam. For more information on this part of the conflict, see SA-2 Guideline.

A political party is typically led by a party leader (the most powerful member and spokesperson representing the party), a party secretary (who maintains the daily work and records of party meetings), party treasurer (who is responsible for membership dues) and party chair (who forms strategies for recruiting and retaining party members, and also chairs party meetings). Most of the above positions are also members of the party executive, the leading organization which sets policy for the entire party at the national level. The structure is far more decentralized in the United States because of the separation of powers, federalism and the multiplicity of economic interests and religious sects. Even state parties are decentralized as county and other local committees are largely independent of state central committees. The national party leader in the U.S. will be the president, if the party holds that office, or a prominent member of Congress in opposition (although a big-state governor may aspire to that role). Officially, each party has a chairman for its national committee who is a prominent spokesman, organizer and fund-raiser, but without the status of prominent elected office holders.

Brooke Foss Westcott (1825–1901) and Fenton J. A. Hort (1828–1892) published an edition of the New Testament in Greek in 1881. They proposed nine critical rules, including a version of Bengel's rule, "The reading is less likely to be original that shows a disposition to smooth away difficulties." They also argued that "Readings are approved or rejected by reason of the quality, and not the number, of their supporting witnesses", and that "The reading is to be preferred that most fitly explains the existence of the others."

The Islamic Golden Age coincided with the Middle Ages in the Muslim world, starting with the rise of Islam and establishment of the first Islamic state in 622. The end of the age is variously given as 1258 with the Mongolian Sack of Baghdad, or 1492 with the completion of the Christian Reconquista of the Emirate of Granada in Al-Andalus, Iberian Peninsula. During the reign of the Abbasid caliph Harun ar-Rashid (786 to 809), the legendary House of Wisdom was inaugurated in Baghdad where scholars from various parts of the world sought to translate and gather all the known world's knowledge into Arabic. The Abbasids were influenced by the Quranic injunctions and hadiths, such as "the ink of a scholar is more holy than the blood of a martyr," that stressed the value of knowledge. The major Islamic capital cities of Baghdad, Cairo, and Córdoba became the main intellectual centers for science, philosophy, medicine, and education. During this period, the Muslim world was a collection of cultures; they drew together and advanced the knowledge gained from the ancient Greek, Roman, Persian, Chinese, Indian, Egyptian, and Phoenician civilizations.

The great majority of asphalt used commercially is obtained from petroleum. Nonetheless, large amounts of asphalt occur in concentrated form in nature. Naturally occurring deposits of asphalt/bitumen are formed from the remains of ancient, microscopic algae (diatoms) and other once-living things. These remains were deposited in the mud on the bottom of the ocean or lake where the organisms lived. Under the heat (above 50 °C) and pressure of burial deep in the earth, the remains were transformed into materials such as asphalt/bitumen, kerogen, or petroleum.

Question: Besides heat, what other requirement is needed to form asphalt?
Answer: pressure.

What is today the Central African Republic has been inhabited for millennia; however, the country's current borders were established by France, which ruled the country as a colony starting in the late 19th century. After gaining independence from France in 1960, the Central African Republic was ruled by a series of autocratic leaders; by the 1990s, calls for democracy led to the first multi-party democratic elections in 1993. Ange-Félix Patassé became president, but was later removed by General François Bozizé in the 2003 coup. The Central African Republic Bush War began in 2004 and, despite a peace treaty in 2007 and another in 2011, fighting broke out between various factions in December 2012, leading to ethnic and religious cleansing of the Muslim minority and massive population displacement in 2013 and 2014.

Another example relates to AIG, which insured obligations of various financial institutions through the usage of credit default swaps. The basic CDS transaction involved AIG receiving a premium in exchange for a promise to pay money to party A in the event party B defaulted. However, AIG did not have the financial strength to support its many CDS commitments as the crisis progressed and was taken over by the government in September 2008. U.S. taxpayers provided over $180 billion in government support to AIG during 2008 and early 2009, through which the money flowed to various counterparties to CDS transactions, including many large global financial institutions.

During the early years of the Cold War from 1946 to 1958, the United States tested 67 nuclear weapons at its Pacific Proving Grounds located in the Marshall Islands, including the largest atmospheric nuclear test ever conducted by the U.S., code named Castle Bravo. "The bombs had a total yield of 108,496 kilotons, over 7,200 times more powerful than the atomic weapons used during World War II." With the 1952 test of the first U.S. hydrogen bomb, code named "Ivy Mike," the island of Elugelab in the Enewetak atoll was destroyed. In 1956, the United States Atomic Energy Commission regarded the Marshall Islands as "by far the most contaminated place in the world."

The most recent major entrant to the browser market is Chrome, first released in September 2008. Chrome's take-up has increased significantly year by year, by doubling its usage share from 8% to 16% by August 2011. This increase seems largely to be at the expense of Internet Explorer, whose share has tended to decrease from month to month. In December 2011, Chrome overtook Internet Explorer 8 as the most widely used web browser but still had lower usage than all versions of Internet Explorer combined. Chrome's user-base continued to grow and in May 2012, Chrome's usage passed the usage of all versions of Internet Explorer combined. By April 2014, Chrome's usage had hit 45%.

Libya began to turn towards socialism. In March 1978, the government issued guidelines for housing redistribution, attempting to ensure the population that every adult Libyan owned his own home and that nobody was enslaved to paying their rent. Most families were banned from owning more than one house, while former rental properties were seized and sold to the tenants at a heavily subsidized price. In September, Gaddafi called for the People's Committees to eliminate the "bureaucracy of the public sector" and the "dictatorship of the private sector"; the People's Committees took control of several hundred companies, converting them into worker cooperatives run by elected representatives.

The purpose of electronic warfare is to deny the opponent an advantage in the EMS and ensure friendly, unimpeded access to the EM spectrum portion of the information environment. Electronic warfare aircraft are used to keep airspaces friendly, and send critical information to anyone who needs it. They are often called "The Eye in the Sky." The roles of the aircraft vary greatly among the different variants to include Electronic Warfare/Jamming (EC-130H), Psychological Operations/Communications (EC-130J), Airborne Early Warning and Control (E-3), Airborne Command Post (E-4B), ground targeting radar (E-8C), range control (E-9A), and communications relay (E-11A)

Before the early 20th century, treatments for infections were based primarily on medicinal folklore. Mixtures with antimicrobial properties that were used in treatments of infections were described over 2000 years ago. Many ancient cultures, including the ancient Egyptians and ancient Greeks, used specially selected mold and plant materials and extracts to treat infections. More recent observations made in the laboratory of antibiosis between microorganisms led to the discovery of natural antibacterials produced by microorganisms. Louis Pasteur observed, "if we could intervene in the antagonism observed between some bacteria, it would offer perhaps the greatest hopes for therapeutics". The term 'antibiosis', meaning "against life", was introduced by the French bacteriologist Jean Paul Vuillemin as a descriptive name of the phenomenon exhibited by these early antibacterial drugs. Antibiosis was first described in 1877 in bacteria when Louis Pasteur and Robert Koch observed that an airborne bacillus could inhibit the growth of Bacillus anthracis. These drugs were later renamed antibiotics by Selman Waksman, an American microbiologist, in 1942. Synthetic antibiotic chemotherapy as a science and development of antibacterials began in Germany with Paul Ehrlich in the late 1880s. Ehrlich noted certain dyes would color human, animal, or bacterial cells, whereas others did not. He then proposed the idea that it might be possible to create chemicals that would act as a selective drug that would bind to and kill bacteria without harming the human host. After screening hundreds of dyes against various organisms, in 1907, he discovered a medicinally useful drug, the synthetic antibacterial salvarsan now called arsphenamine.

The name "Seattle" appears on official Washington Territory papers dated May 23, 1853, when the first plats for the village were filed. In 1855, nominal land settlements were established. On January 14, 1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of trustees managing the city. The town of Seattle was disincorporated January 18, 1867 and remained a mere precinct of King County until late 1869, when a new petition was filed and the city was re-incorporated December 2, 1869 with a Mayor-council government.

Government revenues largely come from sales of fishing licenses, income from the Tuvalu Trust Fund, and from the lease of its highly fortuitous .tv Internet Top Level Domain (TLD). In 1998, Tuvalu began deriving revenue from the use of its area code for premium-rate telephone numbers and from the commercialisation of its ".tv" Internet domain name, which is now managed by Verisign until 2021. The ".tv" domain name generates around $2.2 million each year from royalties, which is about ten per cent of the government's total revenue. Domain name income paid most of the cost of paving the streets of Funafuti and installing street lighting in mid-2002. Tuvalu also generates income from stamps by the Tuvalu Philatelic Bureau and income from the Tuvalu Ship Registry.
