https://en.wikipedia.org/wiki/Microbial%20corrosion | Microbial corrosion, also called microbiologically influenced corrosion (MIC), microbially induced corrosion (MIC) or biocorrosion, is "corrosion affected by the presence or activity (or both) of microorganisms in biofilms on the surface of the corroding material." This corroding material can be either a metal (such as... |
https://en.wikipedia.org/wiki/Equiconsistency | In mathematical logic, two theories are equiconsistent if the consistency of one theory implies the consistency of the other theory, and vice versa. In this case, they are, roughly speaking, "as consistent as each other".
In general, it is not possible to prove the absolute consistency of a theory T. Instead we usua... |
https://en.wikipedia.org/wiki/Aerotolerant%20anaerobe | Aerotolerant anaerobes use fermentation to produce ATP. They do not use oxygen, but they can protect themselves from reactive oxygen molecules. In contrast, obligate anaerobes can be harmed by reactive oxygen molecules.
There are three categories of anaerobes. Where obligate aerobes require oxygen to grow, obligate an... |
https://en.wikipedia.org/wiki/Malthusian%20growth%20model | A Malthusian growth model, sometimes called a simple exponential growth model, is essentially exponential growth based on the idea of the function being proportional to the speed to which the function grows. The model is named after Thomas Robert Malthus, who wrote An Essay on the Principle of Population (1798), one o... |
https://en.wikipedia.org/wiki/Science%2C%20technology%2C%20engineering%2C%20and%20mathematics | Science, technology, engineering, and mathematics (STEM) is an umbrella term used to group together the distinct but related technical disciplines of science, technology, engineering, and mathematics. The term is typically used in the context of education policy or curriculum choices in schools. It has implications for... |
https://en.wikipedia.org/wiki/In-phase%20and%20quadrature%20components | A sinusoid with modulation can be decomposed into, or synthesized from, two amplitude-modulated sinusoids that are in quadrature phase, i.e., with a phase offset of one-quarter cycle (90 degrees or /2 radians). All three sinusoids have the same center frequency. The two amplitude-modulated sinusoids are known as the in... |
https://en.wikipedia.org/wiki/Common%20Base%20Event | Common Base Event (CBE) is an IBM implementation of the Web Services Distributed Management (WSDM) Event Format standard. IBM also implemented the Common Event Infrastructure, a unified set of APIs and infrastructure for the creation, transmission, persistence and distribution of a wide range of business, system and ne... |
https://en.wikipedia.org/wiki/Residue-class-wise%20affine%20group | In mathematics, specifically in group theory, residue-class-wise affine
groups are certain permutation groups acting on
(the integers), whose elements are bijective
residue-class-wise affine mappings.
A mapping is called residue-class-wise affine
if there is a nonzero integer such that the restrictions of
to the r... |
https://en.wikipedia.org/wiki/Rate%20of%20return | In finance, return is a profit on an investment. It comprises any change in value of the investment, and/or cash flows (or securities, or other investments) which the investor receives from that investment over a specified time period, such as interest payments, coupons, cash dividends and stock dividends. It may be me... |
https://en.wikipedia.org/wiki/Tolman%20length | The Tolman length (also known as Tolman's delta) measures the extent by which the surface tension of a small liquid drop deviates from its planar value. It is conveniently defined in terms of an expansion in , with the equimolar radius (defined below) of the liquid drop, of the pressure difference across the droplet'... |
https://en.wikipedia.org/wiki/Pseudocircle | The pseudocircle is the finite topological space X consisting of four distinct points {a,b,c,d } with the following non-Hausdorff topology:
This topology corresponds to the partial order where open sets are downward-closed sets. X is highly pathological from the usual viewpoint of general topology as it fails ... |
