v. t. e. The Corpulence Index ( CI) (also Ponderal Index ( PI) or Rohrer's Index) is a measure of corpulence, or of leanness in other variants, of a person [1] calculated as a relationship between mass and height. [2] It was first proposed in 1921 as the "Corpulence measure" by Swiss physician Fritz Rohrer [3] [4] and hence is also known as ...
In electronics and semiconductor physics, the law of mass action relates the concentrations of free electrons and electron holes under thermal equilibrium. It states that, under thermal equilibrium, the product of the free electron concentration and the free hole concentration is equal to a constant square of intrinsic carrier concentration .

Mass flux. In physics and engineering, mass flux is the rate of mass flow per unit of area. Its SI units are kg m −2 s −1. The common symbols are j, J, q, Q, φ, or Φ ( Greek lowercase or capital Phi ), sometimes with subscript m to indicate mass is the flowing quantity. Mass flux can also refer to an alternate form of flux in Fick's law ...
