List Of ITU-T V-series Recommendations
The ITU-T V-Series Recommendations on Data communication over the telephone network specify the protocols that govern approved modem communication standards and interfaces. Note: the ''wikt:bis#Latin, bis'' and ''wikt:ter#Latin, ter'' suffixes are ITU-T standard designators of successive iterations of a standard (''bis'' and ''ter'' are the Latin words for "twice" and "thrice"). General standards ''Applies to V.1–V.9'' * V.1 is an ITU-T recommendation, entitled ''Equivalence between binary notation symbols and the significant conditions of a two-condition code.'' * V.2 is an ITU-T recommendation, approved in November 1988, titled ''Power levels for data transmission over telephone lines.'' * V.4 is an ITU-T recommendation, approved in November 1988, titled ''General structure of signals of International Alphabet No. 5 code for character oriented data transmission over public telephone networks.'' * V.5 was an ITU-T recommendation, approved in November 1988, titled ''Stand ...

Nerve Agent
Nerve agents, sometimes also called nerve gases, are a class of organic chemistry, organic chemicals that disrupt the mechanisms by which nerves transfer messages to organs. The disruption is caused by the blocking of acetylcholinesterase (AChE), an enzyme that catalyzes the breakdown of acetylcholine, a neurotransmitter. Nerve agents are irreversible acetylcholinesterase inhibitors used as poison. Poisoning by a nerve agent leads to constriction of pupils, profuse salivation, convulsions, and involuntary urination and defecation, with the first symptoms appearing in seconds after exposure. Death by asphyxiation or cardiac arrest may follow in minutes due to the loss of the body's control over Respiration (physiology), respiratory and other muscles. Some nerve agents are readily vaporized or aerosolized, and the primary portal of entry into the body is the respiratory system. Nervous agents can also be absorbed through the skin, requiring that those likely to be subjected to su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VE (nerve Agent)
VE (''S''-(diethylamino)ethyl ''O''-ethyl ethylphosphonothioate) is a "V-series" nerve agent closely related to the better-known VX nerve agent. It was first reported in 1958 as a pesticide. Like most of the agents in the V-series (with the exception of VX), VE has not been extensively studied outside of military science. It is commonly theorized that the so-called "second-generation" V series agents came from a Cold War era Russian chemical weapons development program. They may have been developed sometime between 1950 and 1990. They have similar lethal dose levels to VX (between 10–50 mg) and have similar symptoms and method of action to other nerve agents that act on cholinesterase, and treatment remains the same, but the window for effectively treating second generation V series seizures is shorter. In addition to the standard seizures, some of the second generation V series agents are known to cause coma A coma is a deep state of prolonged unconsciousness in wh ...

VG (nerve Agent)
VG (IUPAC name: ''O'',''O''-diethyl ''S''- -(diethylamino)ethylphosphorothioate) (also called amiton or Tetram) is a "V-series" nerve agent chemically similar to the better-known VX nerve agent. Tetram was the proposed trade name for the substance and amiton its ISO common name when it was tested as an acaricide by ICI in the 1950s. It is now only of historic interest as the first member of the V-series. History By the 1950s, the use of organophosphate insecticides was well established, despite their known toxicity to mammals. For example, parathion had been developed in the 1940s and became widely used in agriculture despite its known oral toxicity. Many chemical companies continued to research this type of acetylcholinesterase inhibitor, seeking to develop alternatives which had greater human safety while retaining their activity on pests. In 1952, Dr. Ranajit Ghosh, a chemist at Imperial Chemical Industries (ICI), investigated organophosphate esters of substituted amino ethan ...

VM (nerve Agent)
VM (Edemo) is a "V-series" nerve agent closely related to the better-known VX nerve agent. Like most of the agents in the V-series (with the exception of VX), VM has not been extensively studied outside of military science. Little is known about this chemical compound other than its chemical formula. It is commonly theorized that the so-called "second-generation" V series agents came from a Cold War era Russian chemical weapons development program. They may have been developed sometime between 1950 and 1990. They have similar lethal dose levels to VX (between 10 and 50 mg) and have similar symptoms and method of action to other nerve agents that act on cholinesterase. The treatment remains the same, but the window for effectively treating second generation V series seizures is shorter.

VR (nerve Agent)
VR (Russian VX, VXr, Soviet V-gas, GosNIIOKhT, GOSNIIOKhT substance No. 33, Agent "November") is a "V-series" Chemical weapon, unitary nerve agent closely related (it is an isomer) to the better-known VX (nerve agent), VX nerve agent. It became a prototype for the series of Novichok agents. According to chemical weapons expert Jonathan B. Tucker, Jonathan Tucker, the first binary formulation developed under the Soviet Foliant program was used to make Substance 33, differing from VX only in the alkyl substituents on its nitrogen and oxygen atoms. "This weapon was given the code name Novichok." History The development of VR started in 1957, after the Soviet Union obtained information about detection of high level of toxicity in phosphorylthiocholines (the same year Lars-Erik Tammelin published his first articles on fluorophosphorylcholines and phosphorylthiocholines in Acta Chemica Scandinavica) by a team from the Soviet Union's Scientific Research Institute No. 42 (NII-42).

VX (nerve Agent)
VX is an extremely toxic chemical synthesis, synthetic chemical compound in the organophosphorus compound, organophosphorus class, specifically, a phosphonate, thiophosphonate. In the class of nerve agents, it was developed for military use in chemical warfare after translational science, translation of earlier discoveries of organophosphate toxicity in pesticide research. In its pure form, VX is an oily, relatively Volatility (chemistry), non-volatile liquid that is amber-like in colour. Because of its low volatility, VX persists in environments where it is dispersed. VX, short for "venomous agent X", is one of the best known of the V nerve agents and originated from pesticide development work at Imperial Chemical Industries (ICI). It was developed further at Porton Down in England during the early 1950s, based on research first done by Gerhard Schrader, a chemist working for IG Farben in Germany during the 1930s. It is now one of a broader V-series of agents which are class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadillac V Series
The Cadillac V series (stylized as V-Series) is a line of high-performance vehicles tuned by the Chevrolet Performance, General Motors Performance division for the Cadillac division of General Motors. Models in the V series tend to vary from one generation to the other. It was introduced in 2003. The V series was initially created as part of the 2000s Cadillac rebranding and the new 'Art & Science' design language to compete directly with German rivals such as BMW M and Mercedes-AMG. The first-ever V series model was the Cadillac CTS, 2004 Cadillac CTS-V which became a successful seller and steered Cadillac in the new direction for the following decade. The letter "V" was chosen as a salute dedicated to post-WWII Cadillacs that featured a V-shape ornament below the crowned wreath logo, the shape itself was never recognized as a letter back then. Most V series Cadillac cars traditionally include high-performance General Motors LS-based small-block engine, V8 engines, transmission ...
