As a result of such chicanery, the voter rolls in many American cities and counties â in such states as South Dakota, Texas, Mississippi, Kentucky, Indiana, West Virginia, Maryland, Iowa, North Carolina, and Missouri â soon included more names than there were residents of voting age in those locales.
From Wikipedia, the free encyclopedia. Microbial corrosion, also called bacterial corrosion, bio-corrosion, microbiologically influenced corrosion, or microbially induced corrosion (MIC), is corrosion caused or promoted by microorganisms, usually chemoautotrophs.It can apply to both metals and non-metallic materials.acterial corrosion may appear in form of pitting corrosion, for example in pipelines of the oil and gas industry. Anaerobic corrosion is evident as layers of metal sulfides and hydrogen sulfide smell.
For example, zinc is often used as a sacrificial anode for steel structures. Galvanic corrosion is of major interest to the marine industry and also anywhere water (containing salts) contacts pipes or metal structures.any structural alloys corrode merely from exposure to moisture in air, but the process can be strongly affected by exposure to certain substances. Corrosion can be concentrated locally to form a pit or crack, or it can extend across a wide area more or less uniformly corroding the surface.
