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.

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.
In fact the. slopes are close to theorical value of 1.00. l Selectivityis the ability of an alternative. method to detect the target analyte from a. wide range of strains and is the lack of inter-. ference from a relevant range of non-target. strains of the alternative method as indi-. cated by ISO 16140 (2003).
