The STK 50 MG, formerly known as the CIS 50MG, [a] is a gas-operated, air-cooled, belt-fed heavy machine gun developed and manufactured by Chartered Industries of Singapore (CIS, now ST Kinetics) in the late 1980s, in response to a request by the Singaporean Defence Ministry to replace the 12.7mm Browning M2HB machine guns then in ubiquitous service with the Singapore Armed Forces (SAF).
The CPW (Compact Personal Weapon) is a multi-caliber submachine gun developed by ST Kinetics as a PDW-class firearm. [2] The prototype is chambered in 9×19mm Parabellum, but the manufacturer assures that the weapon's modular design allows for a simple caliber conversion to either 5.7×28mm or 4.6×30mm.
Surface plasmon resonance (SPR) is a phenomenon that occurs where electrons in a thin metal sheet become excited by light that is directed to the sheet with a particular angle of incidence, and then travel parallel to the sheet. Assuming a constant light source wavelength and that the metal sheet is thin, the angle of incidence that triggers ...
cobalt-precorrin-7 + S-adenosyl-L-methionine cobalt-precorrin-8x + S-adenosyl-L-homocysteine + CO 2 This enzyme catalyses both methylation at C-15 and decarboxylation of the C-12 acetate side chain of cobalt-precorrin-7 in the anaerobic pathway [ 3 ] of adenosylcobalamin biosynthesis in bacteria such as Salmonella typhimurium , Bacillus ...
A U.S. Army graphic detailing the competitors for the program as of December 2020. The Next Generation Squad Weapon (NGSW) program is a United States military program created in 2017 by the U.S. Army to replace the 5.56mm M4 carbine, the M249 SAW light machine gun, and the 7.62mm M240 machine gun, with a common system of 6.8mm cartridges and to develop small arms fire-control systems for the ...
Processes involving cobalt are practiced commercially mainly for the production of C7-C14 alcohols used for the production of surfactants. [ 10 ] [ 11 ] Many hydroformylations have switched from cobalt-based processes to rhodium-based processes, despite the great expense of that metal.
Multi-parametric surface plasmon resonance (MP-SPR) is based on surface plasmon resonance (SPR), an established real-time label-free method for biomolecular interaction analysis, but it uses a different optical setup, a goniometric SPR configuration.
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.
