This paper provides circuit analysis of low-side active-clamp forward converter with synchronous rectification which is widely used as an efficient power supply in various applications. With the use active clamp technique and techniques, losses reduces efficiency increases but number components also increases. A variety soft-switching strategies are employed to reduce switching conduction losse...
A pneumatic olive harvester was developed and evaluated in this study. The components of the machine were limb clamp, vibrating unit, control elements, main tube, air-pressured hoses, valve, power source. measurements that related to development fruit damage, some physical mechanical properties olives fruit-stem system. results demonstrated effectiveness harvest fruits. appropriateness by crite...
Introduction: Abdominal aortic aneurysm is a multifactorial condition which associated with aging and atherosclerosis. During aneurysm surgery, hypotension after aortic clamp removing occure commonly that require specific treatments. This case report showes administration of blood and hemodynamic control methods after aortic unclumping during aortic aneurysm surgery. Patient: A 75–years-o...
Ion channels are responsible for control of cell function in excitable tissues such as heart and brain and also in organs and tissues traditionally thought to be non- excitable including liver and epithelium. In the present research, the effect of lead (Pb2+) on Ca2+ -dependent action potential and currents was studied in F77 neuronal soma membrane of Helix aspersa. For this purpose, action pot...
