The thickness of the bedload layer is a crucial parameter for evaluating sediment transport rates in open channel flow, but it is often determined empirically. Based on the concept of the hydrodynamic diffusion related to particle-particle interactions, an analytical model is proposed in this study for computing the thickness of the bedload layer. The coefficient of diffusion is assumed to be a...
This study investigates geometrical non-linear analysis of composite circular cylindrical shells under external pressure over part of their surfaces and also shells subjected to combined axial compression and triangular external pressure. Donnell non-linear shell theory along with first order shear deformation theory (FOSD) are adopted in the analysis. In the case of combined axial compression ...
In this article we consider the stability and damping problem for 2D Boussinesq equations with partial dissipation near a two parameter family of stationary solutions which includes Couette flow hydrostatic balance. first part show that linearized in an infinite periodic channel evolution is asymptotically stable if any diffusion coefficient non-zero. particular, imposes weaker conditions than ...
The nonequilibrium molecular dynamics computer simulation method was used to study microsegregated block copolymer systems in a selective solvent under a shear flow field. Two polymer concentrations were considered, 0.3 and 0.4, corresponding to the body centered cubic spherical and hexagonal cylindrical zero-shear phases, respectively. As the shear rate increased, both systems exhibited two-st...
We have previously shown that microtubule-associated protein 2 (MAP2) and Tau, two major microtubule-associated proteins, interact with actin differently as measured by low-shear viscosity and that their activities are modified by phosphorylation (Nishida, E., Kotani, S., Kuwaki, T., and Sakai, H. (1982 in Biological Functions of Microtubules and Related Structures (Sakai, H., Mohri, H., and Bo...
(7) was determined on plasma, serum, and Ringer suspensions of erythro-cytes from five mammalian species with different mean corpuscu-lar volume (MCV) : elephant 112 pa, man 90 p3, dog 74 pa, sheep 37 p3, and goat 18 p3. Samples with cell percentages (H) ranging from 5% to maximum packing were tested with a modified version of GDM viscometer at 37 C and shear rates ($ from 52 to 0.052 set-? In ...
Shear stress is an important stimulus to arterial adaptation in response to exercise and training in humans. We recently observed significant reverse arterial flow and shear during exercise and different antegrade/retrograde patterns of shear and flow in response to different types of exercise. The purpose of this study was to simultaneously examine flow-mediated dilation, a largely NO-mediated...

In the intestine, enterotoxigenic Escherichia coli works against peristaltic forces, adhering to the epithelium via the colonization factor antigen I (CFA/I) fimbrial adhesin CfaE. The CfaE adhesin is similar in localization and tertiary (but not primary) structure to FimH, the type 1 fimbrial adhesin of uropathogenic E. coli, which shows shear-dependent binding to epithelial receptors by an al...
