Dominant Seventh Chord
In music theory, a dominant seventh chord, or major minor seventh chord, is a seventh chord, usually built on the fifth degree of the major scale, and composed of a root, major third, perfect fifth, and minor seventh. Thus it is a major triad together with a minor seventh, denoted by the letter name of the chord root and a superscript "7". An example is the dominant seventh chord built on G, written as G7, having pitches G–B–D–F: : Dominant seventh chords contain a strong dissonance – a tritone between the chord's third and seventh. Dominant seventh chords are often built on the fifth scale degree (or dominant) of a key. For instance, in the C major scale, G is the fifth note of the scale, and the seventh chord built on G is the dominant seventh chord, G7 (shown above). In this chord, F is a minor seventh above G. In Roman numeral analysis, G7 would be represented as V7 in the key of C major. Similarly, this chord also occurs on the seventh degree of any natural ...

Aggregate (rocket Family)
The Aggregat series (German for "Aggregate") was a set of ballistic missile designs developed in 1933–1945 by a research program of Nazi Germany's Armed Forces (Wehrmacht). Its greatest success was the A4, more commonly known as the V-2. A1 (1933) The A1 was the first rocket design in the Aggregat series. It was designed in 1933 by Wernher von Braun in a German armed forces research program at Kummersdorf headed by Walter Dornberger. The A1 was the grandfather of most modern rockets. The rocket was long, in diameter, and had a takeoff weight of . The engine, designed by Arthur Rudolph, used a pressure-fed rocket propellant system burning ethanol and liquid oxygen, and produced 2.9 kN (660 lbf) of thrust for 16 seconds. The LOX tank was located within the fuel tank and insulated with a fiberglass material. The rocket was stabilized by a 3 axes gyroscope system in the nose, supplied by Kreiselgeräte G.m.b.H. The rocket could not be rotated for stability as with a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Comet
Air Comet (formerly Air Plus Comet) was an airline based in Madrid, Spain. It operated scheduled long-haul services from Madrid to 13 destinations in Central and South America, as well as services in Europe. Its main base was Terminal 1 at Madrid Barajas Airport. The airline cooperated with airlines such as AeroSur through codeshare agreements. History Air Plus Comet The airline was established on 23 December 1996 as Air Plus Comet and started operations on 1 March 1997, based at Madrid Barajas Airport. On 11 December 1996 Oasis airline ceased operations and their only aircraft, an Airbus A310, and many of their pilots, ground and office personnel, etc. became the foundation of Air Plus Comet. In the post-takeover haste, the airline lacked a commercial name and its ICAO code was MPD, which stood for the last names of its three main executives (Mata, Pascual and Díaz). It mainly operated long-haul charter services from Madrid and Palma de Mallorca to destinations in America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Réti Opening
The Réti Opening is a hypermodern chess opening whose "traditional" or "classic method" begins with the moves: :1. Nf3 d5 :2. c4 White attacks Black's pawn from the , which may occasion 2...dxc4. White may couple this plan with a kingside fianchetto (g3 and Bg2) to create pressure on the light squares in the . The opening is named after Czechoslovakian chess player Richard Réti (1889–1929). The opening is in the spirit of the hypermodernism movement that Réti championed, with the center being dominated from the wings rather than by direct occupation. If White fianchettoes both bishops, castles kingside, and refrains from occupying the center with pawns, the result may be described as the Réti system. In the ''Encyclopaedia of Chess Openings'', Réti Opening is classified as codes A04–A09, where it is closely associated with the King's Indian Attack. History According to Réti, the opening was introduced into master play in the early part of 1923. Schiller, Eric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A7 (classification)
A7 is an amputee sport classification used by the International Sports Organization for the Disabled (ISOD) for people with acquired or congenital amputations. A7 sportspeople have both arms amputated below the elbow, but through or above the wrist joint. Their amputations impact their sport performance, including being more prone to overuse injuries. Sports people in this class are eligible to participate in include athletics, swimming, cycling, lawn bowls, and sitzball. Definition This class is for people who have both arms amputated below the elbow, but through or above the wrist joint. This classification is sometimes abbreviated as B/E. In competing in some sports, this class may have a different name: Performance The nature of a person's amputations in this class can effect their physiology and sports performance. Because they are missing a limb, amputees are more prone to overuse injuries in their remaining limbs. Common problems for intact upper limbs for people ...

Rhodopsin-like Receptors
Rhodopsin-like receptors are a family of proteins that comprise the largest group of G protein-coupled receptors. Scope G-protein-coupled receptors, GPCRs, constitute a vast protein family that encompasses a wide range of functions (including various autocrine, paracrine, and endocrine processes). They show considerable diversity at the sequence level, on the basis of which they can be separated into distinct groups. GPCRs are usually described as "superfamily" because they embrace a group of families for which there are indications of evolutionary relationship, but between which there is no statistically significant similarity in sequence. The currently known superfamily members include the rhodopsin-like GPCRs (this family), the secretin-like GPCRs, the cAMP receptors, the fungal mating pheromone receptors, and the metabotropic glutamate receptor family. There is a specialised database for GPCRs. Function The rhodopsin-like GPCRs themselves represent a widespread protein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
