The Mw7.8 Kunlun earthquake of 14 November, 2001, in the northern Tibetan Plateau of China, was the largest event in the Chinese continental area in the latest 50 years. In this paper, layered visco-elastic models are calculated using the PSGRN/ PSCMP code, and the results are fi tted to the observed post-seismic deformation. We show that a model of a surface anelastic layer of 10km thickness o...
The aim of the study was to show the changes in the great saphenous vein (GSV) wall at consecutive stages in the development of chronic vein disease (CVD) in patients qualified for a surgical procedure after physical examination and Doppler ultrasonography. Four groups of patients were formed (C2, C3, C4 and C5/6) according to clinical stage of the CEAP classification (C - clinical signs, E - a...
The present research attempts to characterize mechanical properties, which are representative of the adhesive and cohesive states of adhesively bonded assemblies, using through-transmission immersion ultrasonic method. Transmission coefficients of an ultrasonic wave incident from different angles are measured for an assembly made of 2 substrates bonded with an adhesive. Knowing thicknesses and ...
We study the lubrication of fluid-immersed soft interfaces and show that elastic deformation couples tangential and normal forces and thus generates lift. We consider materials that deform easily, due to either geometry e.g., a shell or constitutive properties e.g., a gel or a rubber , so that the effects of pressure and temperature on the fluid properties may be neglected. Four different syste...
Soft elastic layers with top and bottom surfaces adhered to rigid bodies are abundant in biological organisms and engineering applications. As the rigid bodies are pulled apart, the stressed layer can exhibit various modes of mechanical instabilities. In cases where the layer's thickness is much smaller than its length and width, the dominant modes that have been studied are the cavitation, int...
