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:
Synovial fluid is a thick (viscous) liquid that acts as a lubricant for the major joints of the body. It is found in small quantities in the spaces between the joints, where the fluid is produced and contained by synovial membranes.ynovial fluid is a thick (viscous) liquid that acts as a lubricant for the major joints of the body.
