Semi-combed yarn represents a type of ring-spun yarn produced by modifying the typical carded and combed yarn manufacturing process. Carded yarn is inferior in quality, while combed yarns are not cost efficient. The semi-combed yarn has therefore emerged as an alternative to fully combed yarn to fac...

Background: Cholecystectomy is one of the most now common abdominal surgeries performed every day. The incidence of bile duct injury (BDI) following open cholecystectomy is only 0.1% - 0.2%. After the introduction of laparoscopic cholecystectomy, the incidence has gone up to 0.4% - 0.7%. The present...

Input current and power factor improvements of single and three-phase rectifiers by switch mode regulators are usually achieved by switching the output of rectifier's diode bridge. In this paper a three phase buck rectifier is proposed which is switched at the input side by one three phase bi-direct...
