Cellular signaling mechanisms are designed to transmit information from the cell surface to specific targets within the cell. Usually, the information is transmitted by intracellular messengers, of which the calcium ion, Ca2+, is one of the most important.

Torsional Oscillators and Longitudinal Oscillators
2010Torsional vibrations in reciprocating engines historically were among the first problems of machine dynamics. They first occurred in marine engines and were calculated and measured by O. frahm as early as 1902. That type of research received a major boost by the demand for lightweight designs for airships and airplanes. In particular, the review of the

The last two chapters showed how transistors—bipolar and FET—work as amplifying devices, using a small current or voltage to control a much larger current. The application to a machine like a record-player, for example, is an obvious one, for the small electric signal produced by the player’s pick-up cartridge must be amplified to a sufficiently large ...
