Bioconcentration. In aquatic toxicology, bioconcentration is the accumulation of a water-borne chemical substance in an organism exposed to the water. [1][2] There are several ways in which to measure and assess bioaccumulation and bioconcentration. These include: octanol-water partition coefficients (K OW), bioconcentration factors (BCF ...
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
Elementary kinetic theory and simple empirical models [1] [2] [3] - viscosity for dilute gas with nearly spherical molecules; Power series [2] [3] - simplest approach after dilute gas; Equation of state analogy [3] between PVT and T P; Corresponding state [2] [3] model - scaling a variable with its value at the critical point
For the study, Salvatore and other researchers analyzed a database of more than 1.5 million people born in Sweden between 1980 and 1998. They also looked at medical, pharmacy, and legal registries ...
Tris (pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C6F5)3B. It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC3 core is planar. It has been described as the “ideal Lewis acid ” because of its high ...
C ratio of 1.12372%. [2] A related standard is the use of wood, which has a δ 13 C of -25‰, as the material for which radiocarbon ages are calibrated. Since different materials have different δ 13 C values, it is possible for two samples of different materials, of the same age, to have different levels of radioactivity and different 14 C ...
In thermodynamics, vapor quality is the mass fraction in a saturated mixture that is vapor; [1] in other words, saturated vapor has a "quality" of 100%, and saturated liquid has a "quality" of 0%. Vapor quality is an intensive property which can be used in conjunction with other independent intensive properties to specify the thermodynamic ...
