C-137 Stratoliner
The Boeing C-137 Stratoliner is a retired VIP transport aircraft derived from the Boeing 707 jet airliner used by the United States Air Force. Other nations also bought both new and used 707s for military service, primarily as VIP or tanker transports. In addition, the 707 served as the basis for several specialized versions, such as the E-3 Sentry AWACS aircraft. The designation C-18 covers several later variants based on the 707-320B/C series. The C-137 should not be confused with the similar Boeing C-135 Stratolifter; although they share a common ancestor the two aircraft have different fuselages. Development US Air Force procurement of the Boeing 707 was very limited, amounting to three Model 707-153s designated VC-137A. When delivered in 1959 these had four 13,500 lb (6123 kg) dry thrust Pratt & Whitney J57 (JT3C6) turbojets; when subsequently re-engined with 18,000 lbf (80.1 kN) dry thrust TF33-P-5 (JT3D) turbofans they were redesignated VC-137B.

Chrysler Royal
Chrysler Eight For production year 1931, Chrysler introduced their first straight eight engine for the Chrysler Imperial, and offered it in the Chrysler Eight Series CD. It borrowed appearance influences from the Cord L-29. The engine used had a displacement that was smaller than the one used in the Imperial Series CG, followed in 1932 with the Chrysler Series CP and an upgraded engine, while both Eights used a wheelbase. The Chrysler Eight offered sweeping fenders, rear suicide doors, dual windshield wipers, dual taillights and dual chrome trumpet horns, sharing an appearance with the 1931 Chrysler Imperial Series CG, and was available with five different two-door body style choices that could accommodate between two through five passengers, and three four-door coachwork choices were offered, to include a sedan convertible and two versions of the Royal Sedan in Standard and Special trim packages. Prices ranged from US$1,495 ($ in dollars ) for the two-door Sport Roadster to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IEC 60320 C18
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 t ...

NGC 185
NGC 185 (also known as Caldwell 18) is a dwarf spheroidal galaxy located 2.08 million light-years from Earth, appearing in the constellation Cassiopeia. It is a member of the Local Group, and is a satellite of the Andromeda Galaxy (M31). NGC 185 was discovered by William Herschel on November 30, 1787, and he cataloged it "H II.707". John Herschel observed the object again in 1833 when he cataloged it as "h 35", and then in 1864 when he cataloged it as "GC 90" within his ''General Catalogue of Nebulae and Clusters''. NGC 185 was first photographed between 1898 and 1900 by James Edward Keeler with the Crossley Reflector of Lick Observatory. Unlike most dwarf elliptical galaxies, NGC 185 contains young stellar clusters, and star formation proceeded at a low rate until the recent past. NGC 185 has an active galactic nucleus (AGN) and is usually classified as a type 2 Seyfert galaxy, though its status as a Seyfert is questioned. It is possibly the closest Seyfert galaxy to Earth ...

HMS C18
HMS ''C18'' was one of 38 C-class submarines built for the Royal Navy in the first decade of the 20th century. The boat survived the First World War and was sold for scrap in 1921. Design and description The C class was essentially a repeat of the preceding B class, albeit with better performance underwater. The submarine had a length of overall, a beam of and a mean draft of . They displaced on the surface and submerged. The C-class submarines had a crew of two officers and fourteen ratings.Gardiner & Gray, p. 87 For surface running, the boats were powered by a single 16-cylinder Vickers petrol engine that drove one propeller shaft. When submerged the propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the C class had a range of at . The boats were armed with two 18-inch (45 cm) torpedo tubes in the bow. They could carry a pair of reload torpedoes, but generally did not as they would have to remove an ...

18th Century
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the Natural environment, environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV, Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected ...

Combat 18
Combat 18 (C18 or 318) is a neo-Nazi terrorist organisation that was founded in 1992. It originated in the United Kingdom, with ties to movements in Canada and the United States. Since then it has spread to other countries, including Germany. Combat 18 members have been suspected of being involved and directly responsible in the deaths of numerous immigrants, non-whites, German politician Walter Lübcke and other C18 members. On 21 June 2019, the government of Canada added Combat 18 (alongside its affiliate Blood & Honour) to its list of terrorist organisations, which was the first time that a far-right group was added to the list. Members in the UK are barred from joining the British Prison Service, the armed forces and police. On 23 January 2020, the German government announced a ban of the German offshoot of Combat 18. Name Combat 18's name is often abbreviated "C18". The "18" in its name is derived from the initials of the Nazi German leader Adolf Hitler: A and H are t ...

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 ...

Sauber C18
The Sauber C18 was the car with which the Sauber team competed in the 1999 Formula One World Championship. It was driven by Frenchman Jean Alesi, in his second year with the team, and Brazilian Pedro Diniz, who joined from Arrows. Design and development The C18 was launched at the Museum Tinguely in Basel, Switzerland. The C18 was a clear development of the C17 from the season prior. The new car did however feature an upgraded Ferrari engine named SPE 03A, rebadged Petronas, and a seven speed gearbox for the first time. The C18 would run Bridgestone tyres, a first for Sauber, as Goodyear withdrew from Formula One before 1999. Bringing Diniz onboard was worth around $7million for the Sauber team, and with the saving on Johnny Herbert's salary, it was estimated Sauber had an additional $12million in budget for developing the C18. The C18 retained a similar livery to the season prior, a two tone blue livery with flashes of red and extensive sponsorship from energy drinks m ...

Colorectal Cancer
Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the large intestine). Signs and symptoms may include blood in the stool, a change in bowel movements, weight loss, and fatigue. Most colorectal cancers are due to old age and lifestyle factors, with only a small number of cases due to underlying genetic disorders. Risk factors include diet, obesity, smoking, and lack of physical activity. Dietary factors that increase the risk include red meat, processed meat, and alcohol. Another risk factor is inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis. Some of the inherited genetic disorders that can cause colorectal cancer include familial adenomatous polyposis and hereditary non-polyposis colon cancer; however, these represent less than 5% of cases. It typically starts as a benign tumor, often in the form of a polyp, which over time becomes cancerous. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
