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. ...

P-type Asteroid
P-type (primitive-type) asteroids have low albedo and a featureless reddish spectrum. It has been suggested that they have a composition of organic-rich silicates, carbon and anhydrous silicates, possibly with water ice in their interior. P-type asteroids are found in the outer asteroid belt and beyond. There are about 33 known P-type asteroids, depending on the classification, including 46 Hestia, 65 Cybele, 76 Freia, 87 Sylvia, 153 Hilda, 476 Hedwig and, in some classifications, 107 Camilla. Taxonomy An early system of asteroid taxonomy was established in 1975 from the doctoral thesis work of David J. Tholen. This was based upon observations of a group of 110 asteroids. The U-type classification was used as a miscellaneous class for asteroids with unusual spectra that did not fit into the C and S-type asteroid classifications. In 1976, some of these U-type asteroids with unusual moderate albedo levels were labeled as M-type. Around 1981, an offshoot of the M-type asteroi ...

MG P-type
The MG P-type is a sports car that was produced by MG (car), MG from 1934 to 1936. This 2-door sports car used an updated version of the Wolseley Motors-designed and made overhead camshaft, crossflow cylinder head, crossflow engine, used in the 1928 Morris Minor (1928)#Engine, Morris Minor and previously fitted in the MG J-type, J-type Midget of 1932 to 1934, driving the rear wheels through a four-speed synchromesh, non-synchromesh gearbox. The chassis was a strengthened and slightly longer version of that used in the J-type with suspension by half-elliptic springs all round with rigid front and rear axles. Steering was initially by a Marles steering gear, Marles Weller and later a Bishop Cam steering box, Bishop Cam system. The two-seat car had a wheelbase of 87 inches (2210 mm) and a track of . Most cars were open two-seaters, but streamlined Airline coupé bodies were also made. The P-type was also available as a four-seater, a car that suffered from a lack of power and p ...

P-type ATPase
The P-type ATPases, also known as E1-E2 ATPases, are a large group of evolutionarily related ion and lipid pumps that are found in bacteria, archaea, and eukaryotes. P-type ATPases are α-helical bundle primary transporters named based upon their ability to catalyze auto- (or self-) phosphorylation (hence P) of a key conserved aspartate residue within the pump and their energy source, adenosine triphosphate (ATP). In addition, they all appear to interconvert between at least two different conformations, denoted by E1 and E2. P-type ATPases fall under the P-type ATPase (P-ATPase) SuperfamilyTC# 3.A.3 which, as of early 2016, includes 20 different protein families. Most members of this transporter superfamily catalyze cation uptake and/or efflux, however one subfamily, the flippases,TC# 3.A.3.8 is involved in flipping phospholipids to maintain the asymmetric nature of the biomembrane. In humans, P-type ATPases serve as a basis for nerve impulses, relaxation of muscles, secre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audi Type P
The Audi Type P was a small two-door sedan/saloon car introduced by Audi in 1931. It was discontinued by 1932. History Jørgen Skafte Rasmussen who had purchased Audiwerke AG in 1928 was concerned that the Audi Zwickau plant was badly underutilized because demand for the expensive luxury cars that Audi produced was still restricted by the economic contraction that had followed the 1929 Stock-market crashes. The other company owned by Rasmussen was Zschopauer Motorenwerke with its brand DKW, which had in 1929 introduced the small rear-wheel drive DKW Typ 4=8. Zschopauer Motorenwerke was the nation's largest producer of motor-bikes, and used a motor-bike style two-stroke engine in their own small cars. Rasmussen became persuaded that the then noisy and lumpy two-stroke engines might be deterring customers: his short-term solution was the Audi Type P which combined the body of the DKW Typ 4=8 with a four-stroke 1,122 cc engine. Rasmussen avoided time as well as development a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermocouple
A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. Thermocouples are widely used as list of temperature sensors, temperature sensors. Commercial thermocouples are inexpensive, interchangeable, are supplied with standard Electrical connector, connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self-powered and require no external form of excitation. The main limitation with thermocouples is accuracy; system errors of less than one degree Celsius (°C) can be difficult to achieve. Thermocouples are widely used in science and industry. Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
