[IRC] The basic unit of discussion on IRC. Once one joins a channel, everything one types is read by others on that channel. Channels are named with strings that begin with a ‘#’ sign and can have topic descriptions (which are generally irrelevant to the actual subject of discussion). Some notable channels are #initgame, #hottub, callahans, and #report. At times of international crisis, #report has hundreds of members, some of whom take turns listening to various news services and typing in summaries of the news, or in some cases, giving first-hand accounts of the action (e.g., Scud missile attacks in Tel Aviv during the Gulf War in 1991).

n

A definite furrow, groove, or tubelike passage.

Any natural or man-made watercourse. The channel capacity of a river is its cross-sectional area in square metres, but the limits of the channel at each bank are not easy to assess. Water in the channel will experience channel resistance which slows or impedes the flow; friction with the bed is the major cause. see bed-floor roughness.

Narrow, deep channels are associated with a regular discharge and coherent bank materials such as clay, while wide and shallow channels develop where discharge is irregular and the bank material incoherent, as with gravel.

Various classifications of channel types have been suggested. The typology may be based on the shape of the channel and its network, the nature of the bank and bed and the way in which these affect the channel, or the capacity of the river to carry sediment. see hydraulic radius, wetted perimeter.

1. A structural or rolled steel shape used in steel construction.
2. A decorative groove, in carpentry or masonry.
3. An enclosure containing the ballast, starter, lamp holders, and wiring for a fluorescent lamp, or a similar enclosure on which filament lamps (usually tubular) are mounted.

In biophysical terms these are the ‘pores’ in semipermeable membranes through which specific physicochemical units, e.g. cations, calcium ions, can pass; the rate of passage of some channels may be much slower than others, hence there is an expansive nomenclature, e.g. slow calcium channel, fast calcium channel.

IN BRIEF: The deeper part of a river or harbor. Also: The band of frequencies on which a radio or television station sends out its signal.

The channel had to be excavated every ten years to keep it passable by ships.
