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.
Corrosion is a natural process, which converts refined metal to their more stable oxide. It is the gradual destruction of materials (usually metals) by chemical reaction with their environment.In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen.ecause corrosion is a diffusion-controlled process, it occurs on exposed surfaces. As a result, methods to reduce the activity of the exposed surface, such as passivation and chromate conversion, can increase a material's corrosion resistance.
