Torque is applied to the central stalk atoms at the F 1. -F. o interface to. constrain their rotation to constant angular velocity Ï = 24 deg/ns. 0.0 to 5.0 ns (0 to 120 deg) of torqued F. 1. rotation, Ï = 24 deg/ns.
A masking agent is a reagent used in chemical analysis which reacts with chemical species that may interfere in the analysis. In sports a masking agent is used to hide or prevent detection of a banned substance or illegal drug like anabolic steroids or stimulants.
