Because solid food takes more time to digest and to break down the protein and send it to the muscles, it can be best to take a protein shake immediately following a workout, since protein shakes only take about 30 minutes to reach the muscle after ingestion.
selectivity. (analytical chemistry). The ability of a type of method or instrumentation to respond to a specified substance or constituent and not to others. (electronics). The ability of a radio receiver to separate a desired signal frequency from other signal frequencies, some of which may differ only slightly from the desired value.
Thermal conductivity is a property of a material that determines the rate at which it can transfer heat. Each material's thermal conductivity is determined by a constant, Î», calculated as: where Q is heat, L is the thickness of the surface, A is the surface area, t is time, and Î´T is the difference in temperature.
