Pharmacodynamics phase:

The pharmacodynamics phase can described the drug action mechanism by which a drug molecule causes its effect on the body.

Onset Phase: According to the pharmacodynamics the onset phase explains a specific action of a drug takes to reach a therapeutic response in a particular time after the drug administration.

Peak Phase: According to the pharmacodynamics the peak phase can describes the time it takes for a drug to reach its maximum therapeutic response (highest blood or plasma concentration).

Duration Phase: According to the pharmacodynamics the duration period can describe the length of time the drug concentration is sufficient to elicit a pharmacologic effect.

Trough level: In the pharmacology and medicine a trough concentration or a trough level is the lowest concentration the drug reached before the administration of next dose.

The business cycle has four phases. The peak, the recession, the trough, and the expansion. During the peak phase you will see the short-term fluctuations due to changes in economic activity. If the real output declines for at least two consecutive quarters than that's when it's considered the recession phase. The lowest point is called the trough phase. The trough phase is where people feel the strain and stress of the financial burden the most. The expansion phase is where...

Peak and off-peak times provide an obvious source of equivalence classes for the start and duration of the call. A call could start during peak or off-peak hours, and it could end in peak or off-peak hours (because the maximum duration of a call is just under an hour, a call can cross the peak/off-peak boundary once, but not twice). A call could also cross over the boundary between days, and this wrapping must be handled correctly. A good set...
