    Fugacity and BCF relate to each other in the following equation: = [6] where Z Fish is equal to the Fugacity capacity of a chemical in the fish, P Fish is equal to the density of the fish (mass/length 3), BCF is the partition coefficient between the fish and the water (length 3 /mass) and H is equal to the Henry's law constant (Length 2 /Time 2) [6]

  3. Tris(pentafluorophenyl)borane - Wikipedia

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

    Tris(pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C 6 F 5) 3 B. It is a white, volatile solid. 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 BC 3 core is planar .

  4. Half-life - Wikipedia

    en.wikipedia.org/wiki/Half-life

    Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic unit for the exponential decay equation. The accompanying table shows the reduction of a quantity as a function of the number of half-lives elapsed.

  5. Survival analysis - Wikipedia

    en.wikipedia.org/wiki/Survival_analysis

    In reliability problems, the expected lifetime is called the mean time to failure, and the expected future lifetime is called the mean residual lifetime. As the probability of an individual surviving until age t or later is S ( t ), by definition, the expected number of survivors at age t out of an initial population of n newborns is n × S ( t ...

  6. Exponential decay - Wikipedia

    en.wikipedia.org/wiki/Exponential_decay

    Specifically, if the individual lifetime of an element of the assembly is the time elapsed between some reference time and the removal of that element from the assembly, the mean lifetime is the arithmetic mean of the individual lifetimes. Starting from the population formula =,

  8. Accelerated life testing - Wikipedia

    en.wikipedia.org/wiki/Accelerated_life_testing

    Accelerated life testing is the process of testing a product by subjecting it to conditions (stress, strain, temperatures, voltage, vibration rate, pressure etc.) in excess of its normal service parameters in an effort to uncover faults and potential modes of failure in a short amount of time.

  9. Equivalent annual cost - Wikipedia

    en.wikipedia.org/wiki/Equivalent_annual_cost

    Calculating how much should be invested in an asset in order to achieve a desired result (i.e., purchasing a storage tank with a 20-year life, as opposed to one with a 5-year life, in order to achieve a similar EAC). [11] Comparing to estimated annual cost savings, in order to determine whether it makes economic sense to invest. [12]
