Distant Seismic Waves from a High-Altitude Source

An experimental study on surgical wound contamination from distant infective source in rabbits

Surgical wound infections are usually encountered due to the endogenous rather than the exogenousinfective sources. The objective of this study was to evaluate the effect of a distant inoculated infective source on the contamination of surgical wounds. Thirty White New Zealand rabbits divided randomly into three control and three treatment equal groups. In treatment groups 24 hrs before surgica...

Seismic noise emission induced by seismic waves

The in situ rock undergoing different kinds of deformation accumulates elastic energy that can be released spontaneously o r under artificial effect. Triggering of energy can also be performed by means of a dynamic excitation caused by elastic waves. W e carried out special field investigations with the use of seismic vibrators (Vibroseis-like sources) to study the effect of the energy release ...

Seismic Surface Waves

Seismic Waves Due to a Shear Fault in a Semi-infinite Medium Part Ii: Moving Source

doubling the corresponding displacements for an infinite medium. The vertical component Uz is much disturbed by the free surface. (2) The SP wave has an appreciable amplitude comparable to that of P wave as pointed out for a point source case by KAWASAKI et al. (1973). Especially in such cases as shallow sources propagate upward, the SP wave becomes a remarkably marked phase. Hence, careful exa...
