In the latter, simplification comes from the use of thin specimens or focal zones which thus essentially reduce the problem to a two-dimensional one. The concern in the present work is with the

Cryogenic Acoustic Microscopy. During this period we have seen the development of infrared microscopy (3), scanning Auger microscopy (4), Raman microscopy (5), scanning laser microscopy (6), ion microscopy (7), X-Ray microscopy (8), tunnelling microscopy (9) and the list seems to be growing every year. All of these microscopes

A recent application is the prediction of yield strength in plain carbon steel using an ultrasonic determination of

It is observed theoretically and experimentally that the magnitude spectra of individual nonoverlapping pulse reflections have approximately the same characteristics as the mag

Our simulations also show that the permeability distribution, especially around the lake, determines the overall pattern of circulat

Contrarily, after the Early Miocene the basalts corresponded to a retro-arc environment installed by the Nazca Plate subduction. Besides, from the

The subcrustal earthquakes have mechanisms which are consistent with one another and these show nearly pure strike slip faulting, with NE oriented P axes.
