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...

BACKGROUND Uncertainties about the pathophysiological processes resulting in cardiac surgery-related acute kidney injury (AKI) in infants concern the relative impact of the most prominent risk factors, the clinical relevance of changes in glomerular filtration rate vs tubular injury, and the usefulness of available diagnostic tools. Structural equation modelling could allow for the assessment o...

This work represents from local earthquakes in study are to evaluate the further our understanding knowledge concerning the an intensive study of coda waves California. The goals of this ability of coda wave analysis to of the earth, and to augment our generation of the coda itself. The methods used here are the simple extensions of single station coda wave techniques used by many workers (e.g....

the destructions caused by many recent earthquakes shows that the subsurface structure directly affects the ground motions. especially in areas with possible seismic hazard expectation, expansion of cities has come up with detailed vulnerability analysis. therefore, site response investigation is a key step in every microzonation study. one of the best approaches for understanding the geologica...
