Webof ppb levels of certain polynuclear aromatic hydrocarbons. Prior to use of thi s method, appropriate sample extraction techniques must be used. Both neat and diluted organic liquids (Method 3580, Waste Dilution) may be analyzed by direct injection. A 2- to 5-uL aliquot of the extract is injected into a gas Webbituminous coal (Ref. 5.3). Coal tar pitch is composed almost entirely of polynuclear aromatic compounds and constitutes 48-65% of the usual grades of coal tar. (Ref. 5.3) The purpose of this work was to evaluate the sampling and analytical method routinely used by OSHA, and to make appropriate modifications if necessary. That method required

Mitosis in multinucleate cells can occur either in a coordinated, synchronous manner where all nuclei divide … See more Some biologists use the term "acellular" to refer to multinucleate cell forms (syncitia and plasmodia), such as to differentiate "acellular" slime molds from the purely "cellular" ones (which do not form such structures). This … See more Syncytia Syncytia are multinuclear cells that can form either through normal biological processes, such as the mammalian placenta, or under … See more Multinucleated cells can also occur under pathological conditions as the consequence of a disturbed cell cycle control (e.g., some See more sims 4 baby icon
