Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how
The density of a material is defined as its mass per unit volume. For a pure substance the density has the same numerical value as its mass concentration.
Ejection fraction (EF) is the fraction of blood in the left and right ventricles pumped out with each heartbeat. EF is applied to both the right
Atomic packing factor
In crystallography, atomic packing factor (APF), packing efficiency or packing fraction is the fraction of volume in a crystal
The volume concentration (also called volume fraction) is defined as the volume of one of the constituents divided by the volume of all constituents of the
