Background: It is shown that hypertension may affect androgens. The role of blood pressure on sperm parameters is matter of debate. The main goal was to evaluate the probable association between systolic and diastolic blood pressure and sperm parameters. Materials and Methods: Semen Sample of men (aged: 27- 45 years old) from 40 infertile cases who attended at Yazd research and clinical center ...

extended abstractintroduction the recognition of behaviors of the atmospheric circulation patterns and effective climatic elements in occurrence of flood is very important, especially because abnormal climate changes such as global warming in recent years tend to change in atmospheric circulation patterns and outbreak climatic inelegances in many areas in the world. intensive and torrential pre...

extended abstractintroductionsiberian high-pressure is one of the most important systems in climatology, which has been focused by all climatologists because of its influence area and expansion zone.unique features of this system including the expansion zone,the intensity of central pressure,which sometimes amounts to more than1075hp pressure at its core,its temperature and moisture characteris...

Blood pressure (BP) is one of the most common vital signs related to cardiovascular diseases. BP traditionally measured by mercury, aneroid, or digital sphygmomanometers; however, these approaches are restrictive, inconvenient, and need a cuff be attached directly patient. Therefore, it clinically important develop an innovative system that can accurately measure without for any direct physical...

1024x768 normal 0 false false false en-us x-none ar-sa background and objective: numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. one physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. in this study, we can predict hem...

The performance of proton-exchange membrane fuel cell cooling system using coolant flow channels enhanced with baffles was numerically investigated. To do this, the maximum temperature of the cooling plate, temperature uniformity and also pressure drop along the flow channels were compared for different cases associated with number of baffles and their dimensions inside the channels. The govern...
