Population genetics. Population genetics is a subfield of genetics that deals with genetic differences within and between populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.
In the fluid-filled case, the wellbore is presumed to be full of either all liquid or gas which gets compressed as afterflow continues into the wellbore. The wellbore storage constant (C) is a function of the wellbore volume (Vw) and the wellbore fluid compressibility (cwb) as shown below: For a fluid-filled wellbore:
In your body you use synovial fluid (body grease). The basic ingredient in the creation of synovial fluid is hyaluronic acid. Hyaluronic acid (HA) may very well be the single most important compound in the structure of the human body. Hyaluronic acid is one type of glycosaminoglycan (GAG).
