troff (/ ˈ t iː r ɒ f /), short for "typesetter roff", is the major component of a document processing system developed by Bell Labs for the Unix operating system. troff and the related nroff were both developed from the original roff.
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).
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map .
Trough (geology), a long depression less steep than a trench; Trough (meteorology), an elongated region of low atmospheric pressure; Trough (physics), the lowest point on a wave; Trough level (medicine), the lowest concentration of a medicine is present in the body over time; Langmuir-Blodgett trough, a laboratory instrument
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 widely used in clinical trials for newer medicines to investigate therapeutic effectiveness and safety.
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
A troffer is a rectangular light fixture that fits into a modular dropped ceiling grid (i.e. 2' by 2' or 2' by 4'). Troffer fixtures have typically been designed to accommodate standard fluorescent lamps (T12, T8, or T5), but are now often designed with integral LED sources.
A watering trough (or artificial watering point) is a man-made or natural receptacle intended to provide drinking water to animals, livestock on farms or ranches or wild animals. History [ edit ]
