Stray current corrosion occurs because: 1) the piping system has been connected accidentally or intentionally to a DC voltage source; 2) the piping does not have metal-to-metal electrical continuity throughout its length; or 3) if the voltage source is AC, copper oxide or one or more naturally occurring minerals coating the pipe interior may ...
It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature , an acetyl group is called an ethanoyl group . An acetyl group contains a methyl group ( −CH 3 ) that is single-bonded to a carbonyl ( C=O ), making it an acyl group .
Biological engineering is a science-based discipline founded upon the biological sciences in the same way that chemical engineering, electrical engineering, and mechanical engineering [7] can be based upon chemistry, electricity and magnetism, and classical mechanics, respectively.
O-GlcNAcylation is the process of adding a single N-acetylglucosamine sugar to the serine or threonine of a protein. [4] Comparable to phosphorylation, addition or removal of N-acetylglucosamine is a means of activating or deactivating enzymes or transcription factors. [4]
To use smaller tubes instead of conventional-sized tubes in air conditioners, heat exchangers must be redesigned including the fin and tube circuits. [12] Design optimization requires the use of computational fluid dynamics to analyze airflow around the tubes and fins, as well as computer simulations of refrigerant flow and temperatures inside the tubes.
Sepiolite, [5] also known in English by the German name meerschaum (/ ˈ m ɪər ʃ ɔː m / MEER-shawm, /-ʃ əm /-shəm; German: [ˈmeːɐ̯ʃaʊm] ⓘ; meaning "sea foam"), is a soft white clay mineral, often used to make tobacco pipes (known as meerschaum pipes).
Culture tubes for biology are usually made of clear plastic (such as polystyrene or polypropylene) by injection molding [2] and are often discarded after use. Plastic test tubes with a screwtop cap are often called "Falcon tubes" after a line manufactured by Becton Dickinson. [3]
