The invasive asexual stages of apicomplexans are not flagellated, and therefore neither of these MTOCs functions as a basal body. In both Toxoplasma and Plasmodium, only the male gamete, known as the microgamete, assembles basal bodies and flagella (Fig. 1d, e). Mature Plasmodium sperm have a single flagella (Fig.
CORROSION CONTROL. Introduction. Corrosion control is a concern whenever water is present in a metalworking fluid. Heat removal is one of the most important functions of a metalworking fluid. Water-based coolants have greater capacity for removing heat than oil. However, water alone in contact with freshly machined metal leads to corrosion.
Process control systems in a chemical plant or oil refinery maintain fluid levels, pressures, temperature, chemical composition, etc. by controlling heaters, pumps and valves. [citation needed] The centrifugal governor of a steam engine, as designed by James Watt in 1788, reduces the throttle valve in response to increases in the engine speed, or opens the valve if the speed falls below the pre-set rate.
