In the cooling mode, the loop supply water temperature (SWT) was maintained at 80 Â°F or higher based on a linear relationship between supply water temperature and cooling signal. The cooling signal directly controlled the fluid cooler fan and spray pump on/off and the fan speed.
The thinner projections, running horizontally between two terminal cisternae are the longitudinal sections of the SR. The sarcoplasmic reticulum (SR) is a membrane bound structure found within muscles cells, that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium (Ca2+).
The sarcoplasmic reticulum is known for its storage of calcium ions in muscle cells.mooth ER also is involved in the uptake and release of calcium to mediate some types of cellular activity. In skeletal muscle cells, for example, the release of â¦ calcium from the smooth ER triggers muscle contraction.   Source: http://encarta.msn.com/encyclopedia_761587444/Endoplasmic_Reticulum.html.
