MG Cars
MG is a British automotive marque founded by Cecil Kimber in the 1920s, and M.G. Car Company Limited was the British sports car manufacturer that made the marque famous. Best known for its open two-seater sports cars, MG also produced saloons and coupés, with engines up to three litres in size and 3.5L in the case of the MGB GT V8. The marque is now owned by Chinese state-owned automaker SAIC Motor Corporation Limited. MG cars had their roots in a 1920s sales promotion sideline of Morris Garages, a retail sales and service centre in Oxford belonging to William Morris. The business's manager, Cecil Kimber, modified standard production Morris Oxfords and added ''MG Super Sports'' to the plate at the nose of the car. A separate M.G. Car Company Limited was incorporated in July 1930. It remained Morris's personal property until 1 July 1935, when he sold it to his holding company, Morris Motors Limited. MG underwent many changes in ownership over the years. Morris's Nuffield O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Monoglyceride
Monoglycerides (also: acylglycerols or monoacylglycerols) are a class of glycerides which are composed of a molecule of glycerol linked to a fatty acid via an ester bond. As glycerol contains both primary and secondary alcohol groups two different types of monoglycerides may be formed; 1-monoacylglycerols where the fatty acid is attached to a primary alcohol, or a 2-monoacylglycerols where the fatty acid is attached to the secondary alcohol. Synthesis Monoglycerides are produced both biologically and industrially. They are naturally present at very low levels (0.1-0.2%) in some seed oils such as olive oil, rapeseed oil and cottonseed oil. They are biosynthesized by the enzymatic hydrolysis of triglycerides by lipoprotein lipase and the enzymatic hydrolysis of diglycerides by diacylglycerol lipase; or as an intermediate in the alkanoylation of glycerol to form fats. Several monoglycerides are pharmacologically active (e.g. 2-oleoylglycerol, 2-arachidonoylglycerol). Industrial p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michaelis–Gutmann Bodies
Michaelis–Gutmann bodies, (M-G bodies) are concentrically layered basophilic inclusions found in Hansemann cells in the urinary tract. They are 2 to 10 μm in diameter, and are thought to represent remnants of phagosomes mineralized by iron and calcium deposits. M-G bodies are a pathognomonic feature of malakoplakia, an inflammatory condition that affects the genitourinary tract. They were discovered in 1902 by Leonor Michaelis Leonor Michaelis (16 January 1875 – 8 October 1949) was a German biochemist, physical chemist, and physician, known for his work with Maud Menten on enzyme kinetics in 1913, as well as for work on enzyme inhibition, pH and quinones.

OpenMG
OpenMG is a digital rights management (DRM) system developed by Sony for managing and protecting digital music data on a personal computer. It was originally designed for audio files in ATRAC3 format; the compliant software, e.g. Sony SonicStage, is usually capable of transcoding MP3 and WAV files to OpenMG/ATRAC3. The file extensions OpenMG-encrypted files use are and . Sister technologies OpenMG Light (for mobile devices) and OpenMG X were also created. Development OpenMG was created alongside MagicGate in an effort to protect digital music copyright. It was released alongside the Memory Stick Walkman and VAIO Music Clip. It is compliant with the Secure Digital Music Initiative (SDMI) version 1.0 industry group specification formed in February 1999. There has been at least one reported case when a security update of Windows XP and Windows 2000 broke OpenMG-compliant software. This issue was later resolved. Method Audio files encrypted using OpenMG cannot be played on anot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MagicGate
MagicGate (MG) is a copy-protection technology introduced by Sony in 1999 as part of the Secure Digital Music Initiative (SDMI). It works by encrypting the content on the device and using MagicGate chips in both the storage device and the reader to enforce control over how files are copied. MagicGate encryption was introduced with Sony's first digital audio players, with the related OpenMG technology being its software counterpart. Since then the encryption has been rolled out to other Sony devices - it is used in the memory cards of the PlayStation 2 and, {{As of, 2004, lc=on, has been introduced into all of Sony's Memory Stick products. Some devices will only accept Memory Sticks which use MagicGate technology. All Memory Stick Duo cards equipped with MagicGate can be identified by a notch located on the rear end of the card. Support Few (USB or PC Card) Memory Stick-compatible card readers support secure MagicGate. Although manufacturers list Memory Stick Pro/Pro Duo (MG) ...

Gravity
In physics, gravity () is a fundamental interaction which causes mutual attraction between all things with mass or energy. Gravity is, by far, the weakest of the four fundamental interactions, approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force and 1029 times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light. On Earth, gravity gives weight to physical objects, and the Moon's gravity is responsible for sublunar tides in the oceans (the corresponding antipodal tide is caused by the inertia of the Earth and Moon orbiting one another). Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circ ...

Smart Grid
A smart grid is an electrical grid which includes a variety of operation and energy measures including: *Advanced metering infrastructure (of which smart meters are a generic name for any utility side device even if it is more capable e.g. a fiber optic router) *Smart distribution boards and circuit breakers integrated with home control and demand response (''behind the meter'' from a utility perspective) **Load control switches and smart appliances, often financed by efficiency gains on municipal programs (e.g. PACE financing) *Renewable energy resources, including the capacity to charge parked (electric vehicle) batteries or larger arrays of batteries recycled from these, or other energy storage. *Energy efficient resources *Sufficient utility grade fiber broadband to connect and monitor the above, with wireless as a backup. Sufficient spare if "dark" capacity to ensure failover, often leased for revenue. Electronic power conditioning and control of the production and distr ...

Level Crossings In The United Kingdom
There are around 6,000 level crossings in the United Kingdom, of which about 1,500 are public highway crossings. This number is gradually being reduced as the risk of accidents at level crossings is considered high. The director of the UK Railway Inspectorate commented in 2004 that "the use of level crossings contributes the greatest potential for catastrophic risk on the railways." The creation of new level crossings on the national network is banned (the exception being reopening unavoidable crossings on new/reopening railway lines, and on heritage railways), with bridges and tunnels being the more favoured options. The cost of making significant reductions, other than by simply closing the crossings, is substantial; some commentators argue that the money could be better spent. Some 5,000 crossings are user-worked crossings or footpaths with very low usage. The removal of crossings can improve train performance and lower accident rates, as some crossings have low rail speed li ...

Motor–generator
A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line. Large motor–generators were widely used to convert industrial amounts of power while smaller motor–generators (such as the one shown in the picture) were used to convert battery power to higher DC voltages. While a motor–generator set may consist of distinct motor and generator machines coupled together, a single unit dynamotor (for dynamo–motor) has the motor coils and the generator coils wound around a single rotor; both the motor and generator therefore share the same outer field coils or magnets.Radio Amateur's Handbook 1976, pub. |
Magnesium
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medium where it ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
