Armoured Personnel Carrier
An armoured personnel carrier (APC) is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I, APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe, an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as a rule, is armed with an integral or organic weapon of less than 20 millimetres calibre." Compared to infantry fighting vehicles (IFVs), which are also used to carry infantry into battle, APCs have less weapon, armament and are not designed to provide direct fire support in battle. Infantry units that travel in APCs are known as mechanized infantry. Some militaries also make a distinction between infantry units that use APCs and infantry units that use IFVs, with the latter being known as armoured infantry. History One of the first armored ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anaphase-promoting Complex
Anaphase-promoting complex (also called the cyclosome or APC/C) is an E3 ubiquitin ligase that marks target cell cycle proteins for degradation by the 26S proteasome. The APC/C is a large complex of 11–13 subunit proteins, including a cullin (ANAPC2, Apc2) and RING (ANAPC11, Apc11) subunit much like SCF complex, SCF. Other parts of the APC/C have unknown functions but are highly Conserved sequence, conserved. It was the discovery of the APC/C (and SCF complex, SCF) and their key role in eukaryotic cell-cycle regulation that established the importance of ubiquitin-mediated proteolysis in cell biology. Once perceived as a system exclusively involved in removing damaged protein from the cell, ubiquitination and subsequent protein degradation by the proteasome is now perceived as a universal regulatory mechanism for signal transduction whose importance approaches that of protein phosphorylation. In 2014, the APC/C was mapped in 3D at a resolution of less than a nanometre, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brügger & Thomet APC
The B&T APC (Advanced Police Carbine) is a family of submachine guns, assault rifles and battle rifles produced and manufactured by B&T (formerly known as Brügger & Thomet) of Switzerland. Announced in 2011, the standard series uses standard 9×19mm (APC9), .40 S&W (APC40), 10mm Auto (APC10), and .45 ACP (APC45) ammunition. History The APC series was designed in the 2000s as a modern submachine gun that would be cheaper to produce than the intermediate cartridge assault carbines, which saw an increase in military usage during this period. Before this point, B&T sold the MP9 and had experience in the manufacture of submachine guns, as well as years of feedback from customers on possible enhancements. The first B&T APCs were produced in 2011. Military adoption On March 29, 2019, B&T was awarded a contract in the U.S. Army's Sub Compact Weapon Production-Other Transaction Agreement (P-OTA) competition for its APC9K submachine gun. The $2.6 million contract included an initial 35 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Army Cadet Force
The Army Cadet Force (ACF), generally shortened to Army Cadets, is a national Youth organisations in the United Kingdom, youth organisation sponsored by the United Kingdom's Ministry of Defence (United Kingdom), Ministry of Defence and the British Army. Along with the Sea Cadet Corps (United Kingdom), Sea Cadet Corps and the Air Training Corps, the ACF make up the Community Cadet Forces. It is a separate organisation from the Combined Cadet Force which provides similar training within principally Private schools in the United Kingdom, private schools. Although sponsored by the Ministry of Defence, the ACF is not part of the British Army, and as such cadets are not subject to military law or military 'call up' but is funded by the MOD. Some cadets do, however, go on to enlist in the armed forces later in life. The Army Cadet Charitable Trust UK (ACCT UK) is a registered charity that acts in an advisory role to the Ministry of Defence and other Government bodies on matters conn ...

Armour-piercing Capped
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly armoured targets such as body armour, bulletproof glass, and lightly armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at a very-high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. Penetration In the context of weaponry, ''penetration'' is the ability of a weapon or projectile to pierce into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonium Perchlorate
Ammonium perchlorate ("AP") is an inorganic compound with the formula . It is a colorless or white solid that is soluble in water. It is a powerful oxidizer. Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant. Its instability has involved it in accidents such as the PEPCON disaster. Production Ammonium perchlorate (AP) is produced by reaction between ammonia and perchloric acid. This process is the main outlet for the industrial production of perchloric acid. The salt also can be produced by salt metathesis reaction of ammonium salts with sodium perchlorate. This process exploits the relatively low solubility of NH4ClO4, which is about 10% of that for sodium perchlorate.Helmut Vogt, Jan Balej, John E. Bennett, Peter Wintzer, Saeed Akbar Sheikh, Patrizio Gallone "Chlorine Oxides and Chlorine Oxygen Acids" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH. AP crystallises as colorless rhombohedra. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allophycocyanin
Allophycocyanin ("other algal blue protein"; from Greek language, Greek: '' (allos)'' meaning "other", '' (phykos)'' meaning “alga”, and '' (kyanos)'' meaning "blue") is a protein from the light-harvesting phycobiliprotein family, along with phycocyanin, phycoerythrin and phycoerythrocyanin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble and therefore cannot exist within the membrane like carotenoids, but aggregate, forming clusters that adhere to the membrane called phycobilisomes. Allophycocyanin absorbs and emits red light (650 and 660 nm max, respectively), and is readily found in Cyanobacteria (also called blue-green algae), and red algae. Phycobilin pigments have fluorescent properties that are used in immunoassay kits. In flow cytometry, it is often abbreviated APC. To be effectively used in applications such as Fluorescence-activated cell sorting, FACS, High-Throughput Screening (HTS) and microscopy, APC needs to be chemically cro ...

Atrial Premature Complexes
Premature atrial contraction (PAC), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common arrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the atria depolarizes before the sinoatrial node and thus triggers a premature heartbeat, in contrast to escape beats, in which the normal sinoatrial node fails, leaving a non-nodal pacemaker to initiate a late beat. The exact cause of PACs is unclear; while several predisposing conditions exist, single isolated PACs commonly occur in healthy young and elderly people. Elderly people that get PACs usually don't need any further attention besides follow-ups due to unclear evidence. PACs are often completely asymptomatic and may be noted only with Holter monitoring, but occasionally they can be perceived as a skipped beat or a jolt in the chest. In most c ...

Argon Plasma Coagulation
Argon plasma coagulation (APC) is a medical endoscopic procedure used to control bleeding from certain lesions in the gastrointestinal tract. It is administered during gastrointestinal endoscopy such as esophagogastroduodenoscopy or colonoscopy. Medical use APC involves the use of a jet of ionized argon gas ( plasma) directed through a probe passed through the endoscope. The probe is placed at some distance from the bleeding lesion, and argon gas is emitted, then ionized by a high-voltage discharge (approx 6 kV). High-frequency electric current is then conducted through the jet of gas, resulting in coagulation of the bleeding lesion. As no physical contact is made with the lesion, the procedure is safe if the bowel has been cleaned of colonic gases, and can be used to treat bleeding in parts of the gastrointestinal tract with thin walls, such as the cecum. See also * Electrocautery Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenacetin
Phenacetin (; acetophenetidin, ''N''-(4-ethoxyphenyl)acetamide) is a pain-relieving and fever-reducing drug, which was widely used following its introduction in 1887. It was withdrawn from medicinal use as dangerous from the 1970s (e.g., withdrawn in Canada in 1973, and by the U.S. Food and Drug Administration in 1983). History Phenacetin was introduced in 1887 in Elberfeld, Germany by German company Bayer, and was used principally as an analgesic; it was one of the first synthetic fever reducers to go on the market. It is also known historically to be one of the first non- opioid analgesics without anti-inflammatory properties. Although paracetamol (acetaminophen) was produced earlier, a historical accident saw it ignored after Joseph von Mering's 1893 assessment. Prior to World War One, Britain imported phenacetin from Germany. During the war, a team including Jocelyn Field Thorpe and Martha Annie Whiteley developed a synthesis in Britain.
