Neuromyelitis Optica
Neuromyelitis optica spectrum disorders (NMOSD), including neuromyelitis optica (NMO), are autoimmune diseases characterized by acute inflammation of the optic nerve (optic neuritis, ON) and the spinal cord (myelitis). Episodes of ON and myelitis can be simultaneous or successive. A relapsing disease course is common, especially in untreated patients. In more than 80% of cases, NMO is caused by immunoglobulin G Autoantibody, autoantibodies to aquaporin 4 (anti-AQP4 diseases, anti-AQP4), the most abundant Aquaporin, water channel protein in the central nervous system. A subset of anti-AQP4-negative cases is associated with antibodies against myelin oligodendrocyte glycoprotein (Anti-MOG associated encephalomyelitis, anti-MOG). Rarely, NMO may occur in the context of other autoimmune diseases (e.g. Connective tissue disease, connective tissue disorders, paraneoplastic syndromes) or infectious diseases. In some cases, the etiology remains unknown (Idiopathic disease, idiopathic NMO). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N-Methylmorpholine N-oxide
''N''-Methylmorpholine ''N''-oxide (more correctly 4-methylmorpholine 4-oxide), NMO or NMMO is an organic compound. This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP. NMO is commercially supplied both as a monohydrate C5H11NO2·H2O and as the anhydrous compound. The monohydrate is used as a solvent for cellulose in the lyocell process to produce cellulose fibers. Uses Solvent of cellulose NMMO monohydrate is used as a solvent in the lyocell process to produce lyocell fiber. It dissolves cellulose to form a solution called dope, and the cellulose is reprecipitated in a water bath to produce a fiber. The process is similar but not analogous to the viscose process. In the viscose process, cellulose is made soluble by conversion to its xanthate derivatives. With NMMO, cellul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitronate Monooxygenase
Nitronate monooxygenase (, NMO) is an enzyme with systematic name ''nitronate:oxygen 2-oxidoreductase (nitrite-forming)''. This enzyme catalyses the following chemical reaction : ethylnitronate + O2 \rightleftharpoons acetaldehyde + nitrite + other products The enzymes from the fungus ''Neurospora crassa'' and the yeast Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitut ...

Normal Move Out
In reflection seismology, normal moveout (NMO) describes the effect that the distance between a seismic source and a receiver (the offset) has on the arrival time of a reflection in the form of an increase of time with offset. The relationship between arrival time and offset is hyperbolic and it is the principal criterion that a geophysicist uses to decide whether an event is a reflection or not. It is distinguished from dip moveout (DMO), the systematic change in arrival time due to a dipping layer. The normal moveout depends on complex combination of factors including the velocity above the reflector, offset, dip of the reflector and the source receiver azimuth in relation to the dip of the reflector. For a flat, horizontal reflector, the traveltime equation is: t^2 = t_0^2 + \frac where ''x'' = offset; ''v'' = velocity of the medium above the reflecting interface; t_0 = travel time at zero offset, when the source and receiver are in the same place. According to W. Harry May ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Measurement Office
The National Measurement and Regulation Office (NMRO) was an executive agency of the UK Government's Department for Business, Innovation and Skills (BIS). Its function were to provide a measurement infrastructure which supports innovation, facilitates fair competition, promotes international trade and protects consumers and the environment. History The agency was created as National Weights and Measures Laboratory (NWML) in 1987 from a reorganisation of the Standards Department when it moved from its previous location in central London to a new, purpose-built facility in Teddington which was officially opened by the Duke of Kent on the 9th of April 1987. Until June 28, 2007 it was an agency of the Department of Trade and Industry. It then became part of the newly formed Department for Innovation, Universities and Skills. In 2009 an agency moved to Department for Business Innovation and Skills and until April 2015 was known as the National Measurement Office (NMO). In April 2015 N ...

RF Connector
An RF connector (radio frequency connector) is a electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection in order to reduce signal reflection and power loss. As the frequency increases, transmission line effects become more important, with small impedance variations from connectors causing the signal to reflect rather than pass through. An RF connector must not allow external signals into the circuit through electromagnetic interference and capacitive pickup. Mechanically, RF connectors may provide a fastening mechanism ( thread, bayonet, braces, blind mate) and springs for a low ohmic electric contact while sparing the gold surface, thus allowing very high mating cycles and reducing the insertion force.
