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.
Cathodic protection (CP) is a technique to control the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. Cathodic protection systems are most commonly used to protect steel, water, and fuel pipelines and tanks; steel pier piles, ships, and offshore oil platforms.icrobial corrosion, or commonly known as microbiologically influenced corrosion (MIC), is a corrosion caused or promoted by microorganisms, usually chemoautotrophs. It can apply to both metallic and non-metallic materials, in the presence or absence of oxygen.
