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 ...
The BIM Collaboration Format (BCF) is a structured file format suited to issue tracking with a building information model. The BCF is designed primarily for defining views of a building model and associated information on collisions and errors connected with specific objects in the view. The BCF allows users of different BIM software, and/or ...
An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, [ 1] describing the enthalpy of a thermodynamic system. [ 2] A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius. [ 3] It shows enthalpy in terms of internal energy , pressure ...
Octanol-water partition coefficient. The n-octanol-water partition coefficient, Kow is a partition coefficient for the two-phase system consisting of n -octanol and water. [1] Kow is also frequently referred to by the symbol P, especially in the English literature. It is also called n-octanol-water partition ratio. [2][3][4]
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and ...
Plot the plan of the loaded area with a scale of z equal to the unit length of the chart (AB). Place the plan on the influence chart in such a manner that the point below which the stress is to be determined in located at the center of the chart. Count the number of elements (M) of the chart enclosed by the plan of the loaded area.
In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1] It is typically a number between 0 and 2, rounded to five ...
