  3. Bioconcentration - Wikipedia

    en.wikipedia.org/wiki/Bioconcentration

    [15] k 1 is the rate constant for chemical uptake from water at the respiratory surface (L*kg −1 *d −1). [15] C WD is the chemical concentration dissolved in water (g*L −1 ). [ 15 ] k 2 ,k E ,k G ,k B are rate constants that represent excretion from the organism from the respiratory surface, fecal excretion, metabolic transformation, and ...

    en.wikipedia.org/wiki/Bromochlorodifluoromethane

    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 ]

    en.wikipedia.org/wiki/Survival_analysis

    Survival analysis is a branch of statistics for analyzing the expected duration of time until one event occurs, such as death in biological organisms and failure in mechanical systems. This topic is called reliability theory, reliability analysis or reliability engineering in engineering, duration analysis or duration modelling in economics ...

  6. Biopharmaceutics Classification System - Wikipedia

    en.wikipedia.org/wiki/Biopharmaceutics...

    The Biopharmaceutics Classification System (BCS) is a system to differentiate drugs on the basis of their solubility and permeability. [1] This system restricts the prediction using the parameters solubility and intestinal permeability. The solubility classification is based on a United States Pharmacopoeia (USP) aperture.

  7. Variant Call Format - Wikipedia

    en.wikipedia.org/wiki/Variant_Call_Format

    The Variant Call Format or VCF is a standard text file format used in bioinformatics for storing gene sequence variations. The format was developed in 2010 for the 1000 Genomes Project and has since been used by other large-scale genotyping and DNA sequencing projects. [1][2] VCF is a common output format for variant calling programs due to its ...

  8. Tris(pentafluorophenyl)borane - Wikipedia

    en.wikipedia.org/wiki/Tris(pentafluorophenyl)borane

    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 ...

  9. Coronary CT calcium scan - Wikipedia

    en.wikipedia.org/wiki/Coronary_CT_calcium_scan

    On average, a single scan will expose a patient to about 2.3 millisieverts of radiation, equivalent to 23 chest x-rays (front and side views). [13] [14] That average covers a wide range of doses depending on equipment type and scanning protocol. Using modern equipment and protocols, a 1 millisievert exposure is possible. [15]
