Soyuz 6 was part of a joint October, 1969, mission with Soyuz 7 and Soyuz 8 that saw the three Soyuz spacecraft in orbit together at the same time, carrying a total of seven cosmonauts. The crew of Georgy Shonin and Valeri Kubasov were meant to take high-quality movie photography of the Soyuz 7 and Soyuz 8 docking, but the rendezvous systems on all three spacecraft failed.
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity. It functions similarly to a searchlight or flashlight reflector to direct radio waves in a narrow beam, or receive radio waves from one particular direction only. Parabolic antennas have some of the highest gains, meaning that they can produce the narrowest beamwidths, of any antenna type. In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave (SHF) frequencies, at which the wavelengths are small enough that conveniently sized reflectors can be used.
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a detector such as a scintillator attached to a charge-coupled device or a direct electron detector.
A ceiling is an overhead interior surface that covers the upper limits of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the roof structure or the floor of a story above. Ceilings can be decorated to taste, and there are many examples of frescoes and artwork on ceilings, especially within religious buildings. A ceiling can also be the upper limit of a tunnel.
The Neutrino Factory is a proposed particle accelerator complex intended to measure in detail the properties of neutrinos, which are extremely weakly interacting fundamental particles that can travel in straight lines through normal matter for thousands of kilometres. Up until the 1990s, neutrinos were assumed to be massless, but experimental results from searches for solar neutrinos and others are inconsistent with this assumption, and thus indicate that the neutrino does have a very small mass.
An I-beam is any of various structural members with an I or H-shaped cross-section. Technical terms for similar items include H-beam, w-beam, universal beam (UB), rolled steel joist (RSJ), or double-T. I-beams are typically made of structural steel and serve a wide variety of construction uses.
Thomas Jefferson National Accelerator Facility (TJNAF), commonly called Jefferson Lab or JLab, is a US Department of Energy National Laboratory located in Newport News, Virginia.
The T95 was an American prototype medium tank developed from 1955 to 1959. These tanks used many advanced or unusual features, such as siliceous-cored armor, new transmissions, and OPTAR fire-control systems. The OPTAR incorporated an electro-optical rangefinder and was mounted on the right side of the turret, and was used in conjunction with the APFSDS-firing 90 mm T208 smoothbore gun, which had a rigid mount without a recoil system. In addition, although the tanks were designed with a torsion beam suspension, a hydropneumatic suspension was fitted, and one of the tanks was fitted with a Solar Saturn gas turbine for demonstration purposes.
Vania Stambolova is a Bulgarian athlete. She competes in the 400 m hurdles and the 400 m event. At the 2006 IAAF World Indoor Championships she won a silver medal over 400 m. She also won a gold medal at the 2006 European Championships. At present, Stambolova is the highest paid female athlete in Bulgaria.
Vania King is a retired American tennis player. A former top-10 doubles player, King won both the Wimbledon and US Open women's doubles titles in 2010 with partner Yaroslava Shvedova, with whom she also reached the final of the 2011 US Open. She won a total of 15 doubles titles on the WTA Tour and reached a career-high ranking of No. 3 in the world. She also ended runner-up in the mixed-doubles final at the French Open in 2009, with Marcelo Melo.
The twist-beam rear suspension is a type of automobile suspension based on a large H or C-shaped member. The front of the H attaches to the body via rubber bushings, and the rear of the H carries each stub-axle assembly, on each side of the car. The cross beam of the H holds the two trailing arms together, and provides the roll stiffness of the suspension, by twisting as the two trailing arms move vertically, relative to each other.
Figuring is the process of final polishing of an optical surface to remove imperfections or modify the surface curvature to achieve the shape required for a given application.
Vânia Sofia Olim Marote de Ribeiro Fernandes is a Portuguese singer from Funchal, Madeira (Portugal).
A T-beam, used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a T-shaped cross section. The top of the T-shaped cross section serves as a flange or compression member in resisting compressive stresses. The web of the beam below the compression flange serves to resist shear stress. When used for highway bridges the beam incorporates reinforcing bars in the bottom of the beam to resist the tensile stresses which occur during bending.
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines.
Vania Rossi is a professional cyclocross bicycle racer from Italy. On 29 January 2010 Rossi was reported positive for EPO CERA by the Italian Olympic Committee. The Comitato Olimpico Nazionale Italiano (CONI) controlled her on 10 January after she finished second in the women's national cyclocross championships. However, on 2 April CONI revealed that the B Sample was returned non-positive. Rossi is the partner of Italian professional road bicycle racer Riccardo Riccò, who himself tested positive for CERA at the 2008 Tour de France.
The Bigelow Expandable Activity Module (BEAM) is an experimental expandable space station module developed by Bigelow Aerospace, under contract to NASA, for testing as a temporary module on the International Space Station (ISS) from 2016 to at most 2028, when the contract can not be extended any further. It arrived at the ISS on 10 April 2016, was berthed to the station on 16 April 2016, and was expanded and pressurized on 28 May 2016. Although originally planned to be a two year test, it has exceeded expectations and is used as additional cargo storage. The module is under ownership of NASA after Bigelow Aerospace suspended operations in 2021.
Havelock Mills in central Manchester were built between 1820 and 1840. It was probably the largest surviving silk mill in the north-west region in the 1970s and had a unique combination of silk and cotton mills on one site. It was a landmark on the Rochdale Canal, overlooking Tib Lock, one of the Rochdale Nine.
Saudia is a genus of large discoidal to reniform forams, with a relatively thick test and complex interior, composed of agglutinated matter, or microgranular calcite. Saudia is known from the Paleocene to middle Eocene of Saudi Arabia, Iraq and the balkans. Related genera include Vania, Sornayina, and Haurania.
Nuclear shaped charges refers to nuclear weapons that focus the energy of their explosion into certain directions, as opposed to a spherical explosion. Edward Teller referred to such concepts as third-generation weapons, the first generation being the atom bomb and the second the H-bomb.
