The professional science master's, or PSM, got its start in 1997 as a way to better and more rapidly equip students with much-needed skills in the science, technology, engineering, and math (STEM) fields. Now nearly 300 PSM programs are offered by KGI and 128 other institutions.
Parkerizing, bonderizing, phosphating, or phosphatizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating.s for all chemical conversion coatings, the Parkerized surface must be completely covered with a light coating of oil to maximize corrosion and wear resistance, primarily through reducing wetting action and galvanic action.
Mezzotint: is an intaglio printmaking process -- or the print made from such a process -- the main feature of which is the production of graduated tone, as in aquatint, but accomplished differently. In mezzotint a multiplicity of small indentations evenly distributed are made in a metal plate. Etching -- soft ground: is a variation on the hard ground method that allows the artist to create a more textured line. 2  In this method the harder ground is mixed with another substance such as axel grease, rolled onto the plate, which is then heated until the ground is tacky.
