The structural channel, C-channel or parallel flange channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering. Its cross section consists of a wide "web", usually but not always oriented vertically, and two "flanges" at the top and bottom of the web, only sticking out on one side ...
In fluid mechanics and hydraulics, open-channel flow is a type of liquid flow within a conduit with a free surface, known as a channel. [ 1 ] [ 2 ] The other type of flow within a conduit is pipe flow .
Mechanosensitive channels are major pathways for the release of cytoplasmic solutes to achieve a rapid reduction of the turgor pressure, therefore avoiding lysis. Gene disruption experiments confirmed that either MscL or MscS channels can rescue bacteria from a strong osmotic shock, while a double knockout of both channels led to lysis. [2]
Strut is normally made of sheet steel, with a zinc coating (), paint, epoxy, powder coat, or other finish.. Strut channel is also manufactured from stainless steel for use where rusting might become a problem (e.g., outdoors, facilities with corrosive materials), from aluminium alloy when weight is an issue or from fiberglass for very corrosive environments.

A particle or photon that enters one of the channels through a small orifice is guaranteed to hit the wall of the channel, due to the channel being at an angle to the plate. The impact starts a cascade of electrons that propagates through the channel, amplifying the original signal by several orders of magnitude, depending on the electric field ...
An application of the channel capacity concept to an additive white Gaussian noise (AWGN) channel with B Hz bandwidth and signal-to-noise ratio S/N is the Shannon–Hartley theorem: C = B log 2 ( 1 + S N ) {\displaystyle C=B\log _{2}\left(1+{\frac {S}{N}}\right)\ }
Using the weight equation above and solving for the free variables, the solution arrived at is = (/), where is the length and is the height of the beam. Assuming that b {\displaystyle b} , L {\displaystyle L} , and M {\displaystyle M} are fixed design variables, the performance index for bending becomes P C R = σ / ρ {\displaystyle P_{CR ...
