  2. Atwater system - Wikipedia

    en.wikipedia.org/wiki/Atwater_system

    The Atwater system, [1] named after Wilbur Olin Atwater, or derivatives of this system are used for the calculation of the available energy of foods.The system was developed largely from the experimental studies of Atwater and his colleagues in the later part of the 19th century and the early years of the 20th at Wesleyan University in Middletown, Connecticut.

  3. Hydrophobicity scales - Wikipedia

    en.wikipedia.org/wiki/Hydrophobicity_scales

    The mobility of water molecules in the "cage" (or solvation shell) is strongly restricted. This leads to significant losses in translational and rotational entropy of water molecules and makes the process unfavorable in terms of free energy of the system.

  4. Hydronic balancing - Wikipedia

    en.wikipedia.org/wiki/Hydronic_balancing

    Hydronic balancing, also called hydraulic balancing, is the process of optimizing the distribution of water in a building's hydronic heating or cooling system by equalizing the system pressure. In a balanced system every radiator is set to receive the proper amount of fluid in order to provide the intended indoor climate at optimum energy ...

    Here, is the molecular weight of water (vapor), is the average molecular weight of air, is the partial pressure of air (not including the partial pressure of water vapor in an air mixture) and can be approximated by knowing the partial pressure of water vapor at the inlet, before dehumidification occurs, ,. From here, all of the previously ...

    BMI. BMI measures a person’s weight compared to their height. It’s a simple division equation. Since it’s such a quick and easy way to get a rough idea of whether you have a healthy weight ...

  9. Biological value - Wikipedia

    en.wikipedia.org/wiki/Biological_value

    A ratio of nitrogen incorporated into the body over nitrogen absorbed gives a measure of protein "usability" – the BV. Unlike some measures of protein usability, biological value does not take into account how readily the protein can be digested and absorbed (largely by the small intestine). This is reflected in the experimental methods used ...
