Electrical power distribution on ships is similar to land based systems. Harmonic distortion is prevalent in both systems and equally detrimental in the modern era. It is important to understand and investigate the effect of harmonics on a ship’s Power Distribution System, when at sea, especially if the ship uses modern electronic variable speed drive (VSD) technology to control its electrical ...

The selective 5-hydroxytryptamine2-(5-HT2)-receptor-blocking agent ketanserin was given in a dose of 10 mg intravenously to nine patients with Raynaud's phenomenon. The effect on blood flow was assessed by photopletysmography and measurments of skin temperature. Digital blood flow and skin temperature increased significantly after ketanserin injection, whereas the placebo (saline 9 g/l) had no ...
