United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Gigabit
The bit is the most basic unit of information in computing and digital communications. The name is a portmanteau of binary digit. The bit represents a logical state with one of two possible values. These values are most commonly represented as either , but other representations such as ''true''/''false'', ''yes''/''no'', ''on''/''off'', or ''+''/''−'' are also commonly used. The relation between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. It may be physically implemented with a two-state device. The symbol for the binary digit is either "bit" per recommendation by the IEC 80000-13:2008 standard, or the lowercase character "b", as recommended by the IEEE 1541-2002 standard. A contiguous group of binary digits is commonly called a ''bit string'', a bit vector, or a single-dimensional (or multi-dimensional) ''bit array''. A group of eight b ...

Gigabase
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, "Watson–Crick" (or "Watson–Crick–Franklin") base pairs (guanine–cytosine and adenine–thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired structure provides a redundant copy of the genetic information encoded within each strand of DNA. The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding proteins ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ganglion Blocker
A ganglionic blocker (or ganglioplegic) is a type of medication that inhibits transmission between preganglionic and postganglionic neurons in the autonomic nervous system, often by acting as a nicotinic receptor antagonist. Nicotinic acetylcholine receptors are found on skeletal muscle, but also within the route of transmission for the parasympathetic and sympathetic nervous system (which together comprise the autonomic nervous system). More specifically, nicotinic receptors are found within the ganglia of the autonomic nervous system, allowing outgoing signals to be transmitted from the presynaptic to the postsynaptic cells. Thus, for example, blocking nicotinic acetylcholine receptors blocks both sympathetic (excitatory) and parasympathetic (calming) stimulation of the heart. The nicotinic antagonist hexamethonium, for example, does this by blocking the transmission of outgoing signals across the autonomic ganglia at the postsynaptic nicotinic acetylcholine receptor.

GB-1
} The GB-1, also known as the "Grapefruit bomb" and as XM-108,379th 2000 p.39. was a glide bomb produced by Aeronca Aircraft for the United States Army Air Forces during World War II. Intended to allow bombers to release bombs from outside the range of enemy defenses, over one thousand GB-1s were used in combat before the end of the war. Design and development The U.S. Army Air Corps – which would later become the U.S. Army Air Forces – initiated development of a glide bomb design in March 1941.Ordway and Wakeford 1960, p.119. Intended to allow bombers to stand off outside the range of enemy flak while releasing their bombload, while also potentially allowing for more precise targeting due to the shallow glide path the bomb would follow, the design resulted in three prototypes; one developed by Aeronca designated GB-1; a design by Bellanca designated GB-2, and the Timm Aircraft-designed GB-3.Parsch 2003 The GB-1 mated a wing and twin-tail empennage of conventional small-ai ...

Steyr GB
The Steyr GB is a double-action 9×19mm Parabellum caliber, large-framed semi-automatic pistol employing a gas-delayed blowback action. As such the GB abbreviation stand for ''Gasbremse'' (gas brake). It was designed in 1968, intended as a replacement for older handguns in Austrian military service. The weapon went into general civilian production in 1982, and in 1988 production ceased. In the late 1970s, an American company founded by Les Rogak, LES Incorporated of Morton Grove, Illinois marketed the Rogak P-18, a close derivative of the Austrian original, but without great commercial success, Originally published in: due to significantly lower manufacturing standards which affected both the appearance and function of the pistol. Both weapons are now regarded as collector's items, the original (Steyr) model commanding higher prices in the American market. Operating mechanism The Steyr GB is a semi-automatic, blowback-operated firearm. It features a unique gas-delayed blowbac ...

Beechcraft GB Traveler
The Beechcraft Model 17 Staggerwing is an American biplane with an atypical negative wing stagger (the lower wing is farther forward than the upper wing). It first flew in 1932. Development At the height of the Great Depression, aircraft executive Walter H. Beech and airplane designer Ted A. Wells joined forces to collaborate on a project to produce a large, powerful, and fast cabin biplane built specifically for the business executive. The Beechcraft Model 17, popularly known as the "Staggerwing", was first flown on November 4, 1932. During its heyday, it was used as an executive aircraft, much as the private jet is now, and its primary competition were the Waco Custom Cabin and Waco Standard Cabin series of biplanes. The Model 17's unusual negative stagger wing configuration (the upper wing staggered behind the lower) and unique shape maximized pilot visibility and was intended to reduce interference drag between the wings (although it was later found to have negligi ...

GB 18030
GB 18030 is a Chinese government standard, described as ''Information Technology — Chinese coded character set'' and defines the required language and character support necessary for software in China. GB18030 is the registered Internet name for the official character set of the People's Republic of China (PRC) superseding GB2312. As a Unicode Transformation Format (i.e. an encoding of all Unicode code points), GB18030 supports both simplified and traditional Chinese characters. It is also compatible with legacy encodings including GB2312, CP936, and GBK 1.0. In addition to the "GB18030 character encoding", this standard contains requirements about which scripts must be supported, font support, etc. As of 2022, in terms of font implementations, "only the Simplified Chinese fonts of the ''Noto Sans CJK'' (Google), ''Source Han Mono'' (Adobe), and ''Source Han Sans'' (Adobe) typeface families are already compliant with GB 18030-2022 Implementation Level 2 .''Microsoft ...
