  3. Bioconcentration - Wikipedia

    en.wikipedia.org/wiki/Bioconcentration

    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]

  4. BIM Collaboration Format - Wikipedia

    en.wikipedia.org/wiki/BIM_Collaboration_Format

    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 ...

    en.wikipedia.org/wiki/Survival_analysis

    A life table summarizes survival data in terms of the number of events and the proportion surviving at each event time point. The life table for the aml data, created using the R software, is shown. Life table for the aml data. The life table summarizes the events and the proportion surviving at each event time point. The columns in the life ...

  6. High-temperature operating life - Wikipedia

    en.wikipedia.org/.../High-temperature_operating_life

    High-temperature operating life (HTOL) is a reliability test applied to integrated circuits (ICs) to determine their intrinsic reliability. This test stresses the IC at an elevated temperature, high voltage and dynamic operation for a predefined period of time. The IC is usually monitored under stress and tested at intermediate intervals.

  7. Basalt fiber - Wikipedia

    en.wikipedia.org/wiki/Basalt_fiber

    Basalt fibers are produced from basalt rocks by melting them and converting the melt into fibers. Basalts are rocks of igneous origin. The main energy consumption for the preparation of basalt raw materials to produce of fibers is made in natural conditions. Basalt fibers are classified into 3 types: Basalt continuous fibers (BCF), used for the ...

  8. Holdridge life zones - Wikipedia

    en.wikipedia.org/wiki/Holdridge_life_zones

    The Holdridge life zones system is a global bioclimatic scheme for the classification of land areas. It was first published by Leslie Holdridge in 1947, and updated in 1967. It is a relatively simple system based on few empirical data, giving objective criteria. [ 1] A basic assumption of the system is that both soil and the climax vegetation ...

  9. Fatigue limit - Wikipedia

    en.wikipedia.org/wiki/Fatigue_limit

    The fatigue limit or endurance limit is the stress level below which an infinite number of loading cycles can be applied to a material without causing fatigue failure. [1] Some metals such as ferrous alloys and titanium alloys have a distinct limit, [2] whereas others such as aluminium and copper do not and will eventually fail even from small ...
