72Sulfite process — The sulfite process produces wood pulp which is almost pure cellulose fibers by using various salts of sulfurous acid to extract the lignin from wood chips in large pressure vessels called digesters. The salts used in the pulping process are… …
73Northern Ireland peace process — The peace process, when discussing the history of Northern Ireland, is often considered to cover the events leading up to the 1994 Provisional Irish Republican Army (IRA) ceasefire, the end of most of the violence of the Troubles, the Belfast (or …
74Chloralkali process — The chloralkali process is an industrial process for the electrolysis of sodium chloride solution (brine). Depending on the method several products beside hydrogen can be produced. If the products are separated, chlorine and sodium hydroxide are… …
75International Mathematical Olympiad selection process — This article describes the selection process, by country, for entrance into the International Mathematical Olympiad.The International Mathematical Olympiad (IMO) is an annual mathematical olympiad for high school students.Each year, each… …
76Opponent process — For the universal psychological and neurological model, see opponent process theory. Opponent colors based on experiment. Deuteranopes see little difference between the two colors in the central column. The color opponent process is a color… …
77Monsanto process — The Monsanto process is an important method for the manufacture of acetic acid by catalytic carbonylation of methanol. This process operates at a pressure of 30–60 atm and a temperature of 150–200 °C and gives a selectivity greater than 99%. It… …
78Rp-process — The rp process (rapid proton capture process) consists of consecutive proton captures onto seed nuclei to produce heavier elements [Lars Bildsten, [http://arxiv.org/abs/astro ph/9709094v1 Thermonuclear Burning on Rapidly Accreting Neutron Stars ] …
79Fiberglass spray lay-up process — is similar to the hand lay up process. The difference comes from the application of the fiber and resin material to the mold. Spray up is an open molding composites fabrication process where resin and reinforcements are sprayed onto a reusable… …
80Castner–Kellner process — The Castner–Kellner process is a method of electrolysis on an aqueous alkali chloride solution (usually sodium chloride solution) to produce the corresponding alkali hydroxide,[1] invented by American Hamilton Castner and Austrian[2] Karl Kellner …
