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.
Stress Corrosion Cracking (SCC). Stress corrosion cracking (SCC) is the cracking induced from the combined influence of tensile stress and a corrosive environment. The impact of SCC on a material usually falls between dry cracking and the fatigue threshold of that material.The required tensile stresses may be in the form of directly applied stresses or in the form of residual stresses, see an example of SCC of an aircraft component.he impact of SCC on a material usually falls between dry cracking and the fatigue threshold of that material.
