Enlisted Rank
An enlisted rank (also known as an enlisted grade or enlisted rate) is, in some armed services, any rank below that of a commissioned officer. The term can be inclusive of non-commissioned officers or warrant officers, except in United States military usage where warrant officers/chief warrant officers are a separate officer category ranking above enlisted grades and below commissioned officer grades. In most cases, enlisted service personnel perform jobs specific to their own occupational specialty, as opposed to the more generalized command responsibilities of commissioned officers. The term "enlistment" refers solely to a military commitment (whether officer or enlisted) whereas the terms "taken on strength" and "struck off strength" refer to a service member being carried on a given unit's roll. Canadian Forces In the Canadian Forces, the term non-commissioned member (NCM) is used. North Atlantic Treaty Organization For the ranks used by the North Atlantic Treaty Organizat ...

E Postcode Area
The E (Eastern) postcode area, also known as the London E postcode area, is the part of the London post town covering much of east London, England. It borders the N postcode area to the west, both north of the tidal Thames. Since closure of the East London mail centre its mail is sorted at Romford Mail Centre together with IG and RM postcode areas. Postal administration The current E postcode area was originally formed in 1866 as a merger of the E and NE areas, which had been created in 1858. In 1917, the postal districts were numbered alphabetically by their most important parish, chapelry, topographical or built environment feature. As of 2004, the district names do not form part of the postal address. High demand caused sector 9 of the E1 postcode district to be split and recoded in 1999 to create an E1W postcode district around Wapping, but the rest of the district did not gain an additional character. When districts are used for purposes other than the sorting of mail, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estetrol
Estetrol (E4), or oestetrol, is one of the four natural estrogenic steroid hormones found in humans, along with estrone (E1), estradiol (E2), and estriol (E3), estetrol is a major estrogen in the body. In contrast to estrone and estradiol, estetrol is a native estrogen of fetal life. Estetrol is produced exclusively by the fetal liver and is found in detectable levels only during pregnancy, with relatively high levels in the fetus and lower levels in the maternal circulation. In addition to its physiological role as a native hormone, estetrol can be used as a medication, see estetrol (medication). Estetrol, in combination with drospirenone, has recently been approved as a new estrogenic component of a combined oral contraceptive (COC) and estetrol alone is in clinical development for the treatment of menopausal symptoms as well as breast and prostate cancer. Biological function So far, the physiological function of estetrol remains unknown. The potential role of estetrol as a m ...

F4 (mathematics)
In mathematics, F4 is the name of a Lie group and also its Lie algebra f4. It is one of the five exceptional simple Lie groups. F4 has rank 4 and dimension 52. The compact form is simply connected and its outer automorphism group is the trivial group. Its fundamental representation is 26-dimensional. The compact real form of F4 is the isometry group of a 16-dimensional Riemannian manifold known as the octonionic projective plane OP2. This can be seen systematically using a construction known as the ''magic square'', due to Hans Freudenthal and Jacques Tits. There are 3 real forms: a compact one, a split one, and a third one. They are the isometry groups of the three real Albert algebras. The F4 Lie algebra may be constructed by adding 16 generators transforming as a spinor to the 36-dimensional Lie algebra so(9), in analogy with the construction of E8. In older books and papers, F4 is sometimes denoted by E4. Algebra Dynkin diagram The Dynkin diagram for F4 is: . W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RCS-4
RCS-4, or 1-pentyl-3-(4-methoxybenzoyl)indole, is a synthetic cannabinoid drug sold under the names SR-19, BTM-4, or Eric-4 (later shortened to E-4), but originally, OBT-199. Pharmacology RCS-4 is a potent cannabinoid receptor agonist, with EC50 values of 146 nM for human CB1 receptors, and 46 nM for human CB2 receptors. All methoxyphenyl regioisomers, and ''N''-butyl homologues of RCS-4 and its regioisomers also display potent agonist activities at CB1 and CB2 receptors. Legality RCS-4 was banned in Sweden on 1 October 2010 as a hazardous good harmful to health, after being identified as an ingredient in "herbal" synthetic cannabis products. It was outlawed in Denmark on 11 March 2011. In August 2011, New Zealand added not only RCS-4 but also its 1-butyl homologue, and the 2-methoxybenzoyl isomers of both these compounds, to a temporary class drug schedule (i.e. equivalent to Class C but reviewed after 12 months, and with personal possession and use of small amounts decrimi ...

Honda E4
The E series was a collection of successive humanoid robots created by the Honda Motor Company between the years of 1986 and 1993. These robots were only experimental, but later evolved into the Honda P series, with Honda eventually amassing the knowledge and experience necessary to create Honda's advanced humanoid robot: ASIMO. The fact that Honda had been developing the robots was kept secret from the public until the announcement of the Honda P2 in 1996. E0, developed in 1986, was the first robot. It walked in a straight line on two feet, in a manner resembling human locomotion, taking around 5 seconds to complete a single step. Quickly engineers realised that in order to walk up slopes, the robot would need to travel faster. The model has 6 degrees of freedom: one in each groin, one in each knee and one in each ankle. Models *E0, developed in 1986. *E1, developed in 1987, was larger than the first and walked at 0.25 km/h. This model and subsequent E-series robots have 12 degree ...

E-4 Process
:''See also Ektachrome for full details of Kodak E-series processes.'' The E-4 process is a now outdated process for developing color reversal (transparency) photographic film, that was introduced in 1966. The process is infamous for two reasons: First, its use of the highly toxic reversal agent tertiary butyl-amine borane (TBAB) (not to be confused with tetra-n-butylammonium bromide, which also has TBAB as abbr.) – as of all boron hydrides. Early releases of the consumer-sized version of the chemistry provided the TBAB in the form of a tablet. This was later changed to loose powder (likely as a countermeasure against inadvertent ingestion of the substance). The use of the reversal agent permits processing of the film without the manual reexposure that its predecessor E-3 required. Kodak's official E-6 process, which replaced Process E-4 for almost all applications, avoids the necessity of TBAB by adding a separate reversal bath containing the tin salt stannous chloride Tin(I ...

Leukotriene E4
Leukotriene E4 (LTE4) is a cysteinyl leukotriene involved in inflammation. It is known to be produced by several types of white blood cells, including eosinophils, mast cells, tissue macrophages, and basophils, and recently was also found to be produced by platelets adhering to neutrophils. It is formed from the sequential conversion of LTC4 to LTD4 and then to LTE4, which is the final and most stable cysteinyl leukotriene. Compared to the short half lives of LTC4 and LTD4, LTE4 is relatively stable and accumulates in breath condensation, in plasma, and in urine, making it the dominant cysteinyl leukotriene detected in biologic fluids. Therefore, measurements of LTE4, especially in the urine, are commonly monitored in clinical research studies. Increased production and excretion of LTE4 has been linked to several respiratory diseases, and urinary LTE4 levels are increased during severe asthma attacks and are especially high in people with aspirin-induced asthma Aspirin exacerba ...

E4-isoprostane
The isoprostanes are prostaglandin-like compounds formed ''in vivo'' from the free radical-catalyzed peroxidation of essential fatty acids (primarily arachidonic acid) without the direct action of cyclooxygenase (COX) enzymes. The compounds were discovered in 1990 by L. Jackson Roberts and Jason D. Morrow in the Division of Clinical Pharmacology at Vanderbilt University. These nonclassical eicosanoids possess potent biological activity as inflammatory mediators that augment the perception of pain. These compounds are accurate markers of lipid peroxidation in both animal and human models of oxidative stress. Elevated levels of isoprostanes are suspected of contributing to increased risk of heart attack in patients taking Coxibs. Isoprostanes and their metabolites have also been shown to be elevated in the urine of cigarette smokers, and have been suggested as biomarkers of oxidative stress in smokers. Abundance Polyunsaturated fatty acids other than arachidonic acid are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corporal
Corporal is a military rank in use in some form by many militaries and by some police forces or other uniformed organizations. The word is derived from the medieval Italian phrase ("head of a body"). The rank is usually the lowest ranking non-commissioned officer. In some militaries, the rank of corporal nominally corresponds to commanding a section or squad of soldiers. By country Argentina NCOs in the Argentine Armed Forces are divided into junior and senior NCOs, with three and four ranks, respectively. The three junior ranks are called "corporal" (cabo) in both the Navy and the Air Force, while in the Army the third rank is called "sergeant" (sargento). National Gendarmerie and Coast Guard junior NCOs ranks are similar to those in the Army and Navy, respectively. Australia Corporal is the second lowest of the non-commissioned officer ranks in the Australian Army, falling between lance-corporal and sergeant. A corporal is usually appointed as a section comman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specialist (rank)
Specialist is a military rank in some countries’ armed forces. Two branches of the United States Armed Forces use the rank. It is one of the four junior enlisted ranks in the United States Army, above private (PVT), private (PV2), and private first class and is equivalent in pay grade to corporal; in the United States Space Force, four grades of specialist comprise the four junior enlisted ranks below the rank of sergeant. Denmark ;Regular forces In the Royal Danish Navy and Royal Danish Air Force, the rank of specialist is branch-specific; "Naval specialist" and "Air force specialist" ( da, Marinespecialist, Flyverspecialist) respectively. The ranks are placed below corporal and above private first class (). They are rated OR-3 within NATO and the rank has the grade of M112 within the Ministry of Defence's pay structure. ;Home guard In 2018, new specialist ranks were introduced to the Danish Home Guard. These new ranks were created to remove the need for leadership trainin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
