Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to ca ...

French Defence
The French Defence is a chess opening characterised by the moves: :1. e4 e6 This is most commonly followed by 2.d4 d5, with Black intending ...c5 soon after, attacking White's and gaining on the . The French has a reputation for solidity and resilience, although some lines such as the Winawer Variation can lead to complications. Black's position is often somewhat in the early game; in particular, the pawn on e6 can impede the of the bishop on c8. Basics Following the opening moves 1.e4 e6, the main line of the French Defence continues 2.d4 d5 (see below for alternatives). White sets up a , which Black immediately challenges by attacking the pawn on e4. The same position can be reached by from a Queen's Pawn Game after 1.d4 e6 2.e4 d5 or the declining of a Blackmar–Diemer Gambit after 1.d4 d5 2.e4 e6. White's options include defending the e4-pawn with 3.Nc3 or 3.Nd2, advancing it with 3.e5, or exchanging it with 3.exd5, each of which leads to different types ...

Double Cluster
The Double Cluster (also known as Caldwell 14) consists of the open clusters NGC 869 and NGC 884 (often designated h Persei and χ (chi) Persei, respectively), which are close together in the constellation Perseus. Both visible with the naked eye, NGC 869 and NGC 884 lie at a distance of about 7,500 light years in the Perseus Arm of the Milky Way galaxy. Membership NGC 869 has a mass of 4,700 solar masses and NGC 884 weighs in at 3,700 solar masses; both clusters are surrounded with a very extensive halo of stars, with a total mass for the complex of at least 20,000 solar masses. They form the core of the Perseus OB1 association of young hot stars. Based on their individual stars, the clusters are relatively young, both 14 million years old. In comparison, the Pleiades have an estimated age ranging from 75 million years to 150 million years. There are more than 300 blue-white super-giant stars in each of the ...

Head And Neck Cancer
Head and neck cancer develops from tissues in the lip and oral cavity (mouth), larynx (throat), salivary glands, nose, sinuses or the skin of the face. The most common types of head and neck cancers occur in the lip, mouth, and larynx. Symptoms predominantly include a sore that does not heal or a change in the voice. Some may experience a sore throat that does not go away. In those with advanced disease, there may be unusual bleeding, facial pain, numbness or swelling, and visible lumps on the outside of the neck or oral cavity. Given the location of these cancers, trouble breathing may also be present. The majority of head and neck cancer is caused by the use of alcohol or tobacco, including smokeless tobacco, with increasing cases linked to the human papillomavirus (HPV). Other risk factors include Epstein-Barr virus, betel quid, radiation exposure, certain workplace exposures. About 90% are pathologically classified as squamous cell cancers. The diagnosis is confirmed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing YC-14
The Boeing YC-14 is a twinjet short take-off and landing (STOL) tactical military transport aircraft. It was Boeing's entrant into the United States Air Force's Advanced Medium STOL Transport (AMST) competition, which aimed to replace the Lockheed C-130 Hercules as the USAF's standard STOL tactical transport. Although both the YC-14 and the competing McDonnell Douglas YC-15 were successful, neither aircraft entered production. The AMST project was ended in 1979 and replaced by the C-X program. Design and development In mid-1970, the USAF began a paper study, the Tactical Aircraft Investigation (TAI), with Boeing, McDonnell Douglas, and other companies to look at possible tactical transport aircraft designs. This study was a precursor to what became the Advanced Medium STOL Transport program. As a part of this program, Boeing began to look at various high-lift aircraft configurations. Boeing had earlier proposed an underwing externally blown flap solution for their competitor for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IEC 60320
IEC 60320 Appliance couplers for household and similar general purposes is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. Different types of connector (distinguished by shape and size) are specified for different combinations of current, temperature and earthing requirements. Unlike IEC 60309 connectors, they are not coded for voltage; users must ensure that the voltage rating of the equipment is compatible with the mains supply. The standard uses the term ''coupler'' to encompass connectors on power cords and power inlets and outlets built into appliances. The first edition of IEC 320 (later renumbered IEC 60320) was published in 1970. Terminology ''Appliance couplers'' enable the use of standard inlets and country-specific cord sets which allow manufacturers to produce ...

Carbon-14
Carbon-14, C-14, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California. Its existence had been suggested by Franz Kurie in 1934. There are three naturally occurring isotopes of carbon on Earth: carbon-12 (), which makes up 99% of all carbon on Earth; carbon-13 (), which makes up 1%; and carbon-14 (), which occurs in trace amounts, making up about 1 or 1.5 atoms per 1012 atoms of carbon in the atmosphere. Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 () through beta decay. A gra ...

Fokker C
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

14th Century
As a means of recording the passage of time, the 14th century was a century lasting from 1 January 1301 ( MCCCI), to 31 December 1400 ( MCD). It is estimated that the century witnessed the death of more than 45 million lives from political and natural disasters in both Europe and the Mongol Empire. West Africa experienced economic growth and prosperity. In Europe, the Black Death claimed 25 million lives wiping out one third of the European population while the Kingdom of England and the Kingdom of France fought in the protracted Hundred Years' War after the death of Charles IV, King of France led to a claim to the French throne by Edward III, King of England. This period is considered the height of chivalry and marks the beginning of strong separate identities for both England and France as well as the foundation of the Italian Renaissance and Ottoman Empire. In Asia, Tamerlane (Timur), established the Timurid Empire, history's third largest empire to have been ever establ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
