PMA-2 Mine
The PMA-2 is a Yugoslavian blast antipersonnel mine. Sometimes referred to as the 'Pašteta', due to its superficial resemblance to a meat-pâté tin. The mine is constructed from dark green plastic, with a distinctive plunger which has six petals radiating from it. Overview The mine is armed by removing a pin which blocks the downward travel of the six-pronged plunger. After removing the arming pin, sufficient pressure on the plunger (by the victim's foot) forces it downwards into the main fuze body, which ignites a friction-sensitive pyrotechnic composition. The burning pyrotechnic composition flashes through to the detonator which fires, initiating a small RDX booster pellet which in turn detonates the main TNT explosive charge. Generally, PMA-2 mines are buried in such a way that only the star-shaped plunger is visible above ground. However, although this mine is not completely concealed (unlike so many others), it can be very difficult to spot it, particularly in heavy ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Trinitrotoluene
Troponin T (shortened TnT or TropT) is a part of the troponin complex, which are proteins integral to the contraction of skeletal and heart muscles. They are expressed in skeletal and cardiac myocytes. Troponin T binds to tropomyosin and helps position it on actin, and together with the rest of the troponin complex, modulates contraction of striated muscle. The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. It was discovered by the German physician Hugo A. Katus at the University of Heidelberg, who also developed the troponin T assay. Subtypes * Slow skeletal troponin T1, TNNT1 (19q13.4, ) * Cardiac troponin T2, TNNT2 (1q32, ) * Fast skeletal troponin T3, TNNT3 (11p15.5, ) Reference values The 99th percentile cutoff for cardiac troponin T (cTnT) is 0.01 ng/mL. The reference range for the high sensitivity troponin T is a normal 52 ng/L. Backgr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
