As 37 PstK/36. 114 pieces were bought from Bofors in 1938–39 (some of them were returned to Sweden in 1940), 42 Polish-made guns were received from Germans in 1940–41 and 355 were produced by local manufacturers Tampella and VTT ( Valtion Tykkitehdas – State Artillery Factory) in 1939–41.
O-phosphoseryl-tRNASec kinase (EC 2.7.1.164, PSTK, phosphoseryl-tRNA[Ser]Sec kinase, phosphoseryl-tRNASec kinase) is an enzyme with systematic name ATP:L-seryl-tRNASec O-phosphotransferase. [ 1 ] [ 2 ] [ 3 ] This enzyme catalyses the following chemical reaction
At the time, Finland was also in the process of scrapping its stock of obsolete 75 PstK 40 anti-tank guns (German 7.5 cm Pak 40). [3] The existing 95 S 58-61 recoilless rifle was theoretically suitable, but its backblast was a remarkable downside, and the old ammunition types didn't offer much to defeat the reactive and composite armour.

HVAF coating technology is the combustion of propane in a compressed air stream. Like HVOF, this produces a uniform high velocity jet. HVAF differs by including a heat baffle to further stabilize the thermal spray mechanisms. Material is injected into the air-fuel stream and coating particles are propelled toward the part. [4]
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
This makes it suitable for coating temperature-sensitive substrates, such as plastics and certain metals, without causing damage or deformation. [ 9 ] PVD technologies can be scaled from small laboratory setups to large industrial systems, offering flexibility for different production volumes and sizes.
Sputter coating in scanning electron microscopy is a sputter deposition process [clarification needed] to cover a specimen with a thin layer of conducting material, typically a metal, such as a gold/palladium (Au/Pd) alloy. A conductive coating is needed to prevent charging of a specimen with an electron beam in conventional SEM mode (high ...
This makes them relatively expensive compared to other coating technologies. Unlike many other coating methods, they can however handle coatings with a very wide range of viscosities, from 1 to more than 50000 mPas, and are capable of producing extremely polished finishes on the coatings they apply. They have been produced in a variety of 3 ...
