it is well known that ground-shaking site effect caused by an earthquake can vary significantly within a small distance. this is because at sites having soft soil and/or topographic and basement undulations, seismic energy gets trapped, leading to amplification of vibration that may cause considerable damage to man-made structures. theoretical analysis and observational data have shown that eac...

evaluation of range conditions and plant diversity circumstances can help to rangeland managers who establish their managerial approaches on the basis of ecological capabilities of rangeland ecosystems. hence, surveying of rangelands was done in four sites of northern alborz mt. including western alborz (masooleh site), west to middle alborz (javaherdeh site), central area (polour site), and ea...

Surgical site infection (SSI) surveillance was examined in gastric cancer patients who had undergone an open gastrectomy between 1997 and 2003 at Keio University Hospital in Tokyo, Japan. National Nosocomial Infections Surveillance (NNIS) reports and several studies have discussed SSI risk factors, but only open gastrectomy was analyzed by regression analysis. The purpose of this study was to e...

a microgravity survey was conducted for detecting the sink-holes at site of a power plant. pits, man-made tunnels and canals were considered as topographical effects and were corrected. to show the capability of the method two sites in a power plant have been surveyed for existing areas which can be affected by sink-holes overnight. ground shakes due to the running facilities were also preventi...
