S-type Asteroid
S-type (stony-type or silicaceous-type) asteroids are asteroids with a spectral type that is indicative of a siliceous (i.e. stony) mineralogical composition, hence the name. They have relatively high density. Approximately 17% of asteroids are of this type, making it the second-most common after the carbonaceous C-type. Characteristics S-type asteroids, with an astronomical albedo of typically 0.20, are moderately bright and consist mainly of iron- and magnesium-silicates. They are dominant in the inner part of the asteroid belt within 2.2 AU, common in the central belt within about 3 AU, but become rare farther out. The largest are 3 Juno (about 240–250 km across) and 15 Eunomia (230 km), with other large S-types being 29 Amphitrite, 532 Herculina and 7 Iris. These largest S-types are visible in 10x50 binoculars at most oppositions; the brightest, 7 Iris, can occasionally become brighter than +7.0, which is a higher magnitude than any asteroid except ...

S Type Fuse
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated, it is an open circuit, and must be replaced or rewired, depending on its type. Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity, and response times, depending on the application. The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Wiring regulations usually define a maximum fuse current rating for particular circuits. A fuse can be used to mitigate short circuits, overloading, mismatched load ...

S-type Granite
S-type granites are a category of granites first proposed in 1974. They are recognized by a specific set of Mineralogy, mineralogical, Geochemistry, geochemical, textural, and Isotope, isotopic characteristics. S-type granites are over-saturated in aluminium, with an ASI index greater than 1.1 where ASI = Al2O3 / (CaO + Na2O +K2O) in mol percent; Petrography, petrographic features are representative of the chemical composition of the initial magma as originally put forth by Chappell and White are summarized in their table 1. Mineralogy Major minerals (present in amounts > 5 volume%) Like all Granite, granites, the modal mineralogy of S-type granites are dominated by Alkali feldspar, alkali- and plagioclase feldspars and quartz. Thus, S-type granites are silica over-saturated (contain quartz), and do not contain feldspathoids. An interesting feature of S-type granites, at the hand sample scale, is that alkali-feldspars are typically white in color (rather than pink) excluding sa ...

S-type Star
An S-type star (or just S star) is a cool giant star with approximately equal quantities of carbon and oxygen in its atmosphere. The class was originally defined in 1922 by Paul Merrill for stars with unusual absorption lines and molecular bands now known to be due to s-process elements. The bands of zirconium monoxide (ZrO) are a defining feature of the S stars. The carbon stars have more carbon than oxygen in their atmospheres. In most stars, such as class M giants, the atmosphere is richer in oxygen than carbon and they are referred to as ''oxygen-rich stars''. S-type stars are intermediate between carbon stars and normal giants. They can be grouped into two classes: ''intrinsic'' S stars, which owe their spectra to convection of fusion products and s-process elements to the surface; and ''extrinsic'' S stars, which are formed through mass transfer in a binary system. The intrinsic S-type stars are on the most luminous portion of the asymptotic giant branch, a stage of thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Star
A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved as separate stars using a telescope, in which case they are called ''visual binaries''. Many visual binaries have long orbital periods of several centuries or millennia and therefore have orbits which are uncertain or poorly known. They may also be detected by indirect techniques, such as spectroscopy (''spectroscopic binaries'') or astrometry (''astrometric binaries''). If a binary star happens to orbit in a plane along our line of sight, its components will eclipse and transit each other; these pairs are called ''eclipsing binaries'', or, together with other binaries that change brightness as they orbit, ''photometric binaries''. If components in binary star systems are close enough, they can gravitationally distort each other's outer stellar atmospheres. ...

Bedford S Type
The Bedford S is a heavy lorry produced in Great Britain between 1950 and 1959. Launched at the Commercial Vehicle Show in 1950, it was the largest Bedford lorry available at the time. Originally available only with a petrol engine, a diesel was added in 1953. The lorry proved popular amongst haulers and general traders, for fire engines, and was used for the first liquid egg tanker in 1966. Description The S was a conventional lorry and available in three wheelbases, , and . At introduction, the lorry was fitted with a 6-cylinder Bedford petrol engine that produced at 3200 rpm. Drive was through a four-speed manual gearbox featuring synchromesh on the top three gears, and final drive in the rear axle was by hypoid gears. The Perkins R6 diesel engine was made an option in 1953, soon joined by the Leyland O.350, and Bedford's own diesel in 1957. These were rated at between . History The S was launched at the Commercial Vehicle Show in 1950. Known as the "Big Bedford", it w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jensen S-type
The Jensen S-type is a car built by Jensen Motors from 1936 until 1941 as both a saloon and a convertible. It was the firm's first volume production car, based on Ford V8 engines from the United States, and chassis parts from Ford of Britain sourced through M B K Motors. The car was built on a steel chassis and used aluminium for the body panels. The car was sold with either a or a Ford flathead V8 engine, equipped with two downdraft carburetors, Vertex ignition, and a Columbia overdrive rear axle. The cars were available in three body styles: 2-door convertible, 3-door tourer, and 4-door saloon. In total, there were about 50 S-type cars built by Jensen in their West Bromwich West Bromwich ( ), commonly known as West Brom, is a market town in the borough of Sandwell, in the county of the West Midlands (county), West Midlands, England.

Renault S-Type Engine
The 8140 was a diesel engine made by Sofim for cars. Originally introduced as a swirl chamber, naturally aspirated diesel it was mostly used in commercial vehicles worldwide. At the time of introduction, the 8140's overhead camshaft layout (driven by a toothed timingbelt) was unexpected in a diesel engine, which were typically overhead valve designs. Turbocharging the original engine, the design of which was finished in 1974, was impeded until 1985 due to restrictions of the original design. Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development. Before entering the market, Fiat tested the Sofim engine in its 131 model during the 1977 London-Sydney Marathon. First direct injection models also appeared in the mid-1980s. Additionally to the Fiat designation 8140 some engines got a Renault tag (S8 for indirect injection, S9 for direct injection). 2.0 L version In the early beginning there was a four-cylinder , ca ...

Soviet S-class Submarine
The S-class or Srednyaya (, "medium") submarines were part of the Soviet Navy's underwater fleet during World War II. Unofficially nicknamed Stalinets (, "follower of Joseph Stalin, Stalin"; not to be confused with the submarine Leninets-class submarine, L-class L-2 ''Stalinets'' of 1931), boats of this class were the most successful and achieved the most significant victories among all Soviet submarines. They sank of merchant shipping and seven warships, which accounts for about one-third of all tonnage sunk by Soviet submarines during the war. Project history The history of the S class represents a turn in warship development. It was a result of international collaboration between Soviet Union, Soviet and German engineers that resulted in two different (but nevertheless related) classes of submarines often pitted against each other in the war. In the early 1930s the Soviet government started a massive program of general rearmament, including naval expansion. Submarines were o ...
