A New Method for Modeling Bottom Shear Stress under Irregular Waves

Bottom Shear Stress Formulations to Compute Sediment Fluxes in Accelerated Skewed Waves

As waves travel and shoal towards a beach, their surface elevation becomes peaky (sharp crests) and asymmetric relative to the vertical. Within a wave period, the corresponding orbital velocity near the bottom shows a similar (time) variation and it is recognized that these nonlinearities are responsible for sediment transport. The resulting wave-induced bottom shear stresses are required for m...

Mathematical Modeling of Intravascular Blood Coagulation under Wall Shear Stress

Increased shear stress such as observed at local stenosis may cause drastic changes in the permeability of the vessel wall to procoagulants and thus initiate intravascular blood coagulation. In this paper we suggest a mathematical model to investigate how shear stress-induced permeability influences the thrombogenic potential of atherosclerotic plaques. Numerical analysis of the model reveals t...

A method for measuring the critical shear stress of cohesive soils

A novel method for measuring the erythrocyte deformability, under oscillatory shear stress.

A novel apparatus for detecting a subtle decrease in erythrocyte deformability was developed. The oscillatory shape change of erythrocytes was monitored under an oscillatory shear stress (modulating the oscillation frequency in the range of 9-90 dyn/cm2). The ellipsoidal deformation of intact erythrocytes perfectly followed the oscillatory force of up to about 2 Hz, but the diamide-treated cell...
