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.
The thermal conductivity of a material is a quantitative measure of how much heat will flow through a material per unit time for a given temperature gradient. In the simplest materials the mechanism of heat transfer may be described at the microscopic level as transfer of energy through collisions between atoms and molecules. In a higher temperature region region the atoms and molecules have more kinetic energy than in a low temperature region.
