Extended abstract Introduction The vital need for river management is understood and predicts bank erosion processes. River bank erosion is one of the sediment major sources for many rivers across the world. Bank erosion is a key process in fluvial dynamics, affecting a wide range of physical, ecological and socio-economic issues in the fluvial environment. These include the establishm...
BACKGROUND This study describes a new method for determining site-specific vascular shear stress using dynamic measures of shear rate and blood viscosity (BV) in the carotid arteries, and examines characteristics of carotid arterial shear stress among patients with lacunar infarction. METHODS Vascular shear stress measurements were conducted in 37 patients (17 lacunar infarction patients and ...
in this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from sm to gm on behavior of sandy soil. in this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 kpa were carried out in ...
Once plaques intrude into the lumen, the shear stress they are exposed to alters with hitherto unknown consequences for plaque composition. We investigated the relationship between shear stress and strain, a marker for plaque composition, in human coronary arteries. We imaged 31 plaques in coronary arteries with angiography and intravascular ultrasound. Computational fluid dynamics was used to ...
Matrix resins of carbon fiber-epoxy composites with different numbers of epoxy functional groups were prepared, and their properties were compared to optimize the matrix resin composition. To understand the bonding strengths between the carbon fiber and epoxy resins in monofilaments and micro-sized resin beads, the interfacial shear strength (IFSS) was measured using the microdroplet technique....
Endothelial cells (ECs) sense shear stress and transduce blood flow information into functional responses that play important roles in vascular homeostasis and pathophysiology. A unique feature of shear-stress-sensing is the involvement of many different types of membrane-bound molecules, including receptors, ion channels and adhesion proteins, but the mechanisms remain unknown. Because cell me...
