By Stephanie Liou 26 Jun, 2011 Glutamate Toxicity. Glutamate is a powerful excitatory neurotransmitter that is released by nerve cells in the brain. It is responsible for sending signals between nerve cells, and under normal conditions it plays an important role in learning and memory.
Fg. Fg is an abbreviation used in physics and engineering for the force exerted by gravity on an object, normally represented in units such as the newton. Fg is always a conservative force. see more on Definitions.net Â».
Cv = Valve flow coefficient, dimensionless; Q = Volumetric flow rate, gpm; q = Volumetric flow rate, scfh; Gf = Liquid specific gravity at upstream conditions [ratio of density of liquid at flowing temperature to density of water at 15.6Â°C (60Â°F)], dimensionless Gg = Gas specific gravity (ratio of flowing gas to density of air with both at standard conditions, which is equal to the ratio of the molecular weight of gas to the molecular weight of air), dimensionless
