In a medicine that is administered periodically, the trough level should be measured just before the administration of the next dose in order to avoid overdosing. [3] A trough level is contrasted with a "peak level" (C max), which is the highest level of the medicine in the body, and the "average level", which is the mean level over time. It is ...
Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line.
Shortwave trough with associated vorticity. A shortwave or shortwave trough is an embedded kink in the trough / ridge pattern. Its length scale is much smaller than that of and is embedded within longwaves, which are responsible for the largest scale (synoptic scale) weather systems.
In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones).
Peak-to-trough ratio in pharmacokinetics is the ratio of peak (C max) and trough (C min) levels of a drug over its dosing interval (τ) at steady state.. Peak-to-trough ratio (PTR), also known as peak-to-trough variation or peak-to-trough fluctuation, is a parameter in pharmacokinetics which is defined as the ratio of C max (peak) concentration and C min (trough) concentration over a dosing ...
A trough is the opposite of a crest, so the minimum or lowest point of the wave. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line).
Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
Two sun dogs often flank the Sun within a 22° halo. The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun ...
