Although bulk changes in red blood cell concentration between vessels have been well characterised, local distributions are generally overlooked. Red blood cells aggregate, deform and migrate within vessels, forming heterogeneous distributions which have considerable effect on local haemodynamics. The present study reports data on the local distribution of human red blood cells in a sequentiall...

A two-phase model for the flow of blood in narrow tubes is described. The model consists of a central core of suspended erythrocytes and a cell-free layer surrounding the core. It is assumed that the viscosity in the cell-free layer differs from that of plasma as a result of additional dissipation of energy near the wall caused by the red blood cell motion near the cell-free layer. A consistent...

FORTY YEARS AGO, this month, I started in practice, I confess without the benefit of vocational training; that came two months later when my chief had his first coronary. I was extremely fortunate in becoming assistant, and later partner, to John Taggart of the Antrim Road, one of the most distinguished practitioners of his day. Taggart was a County Antrim man, with all the bluntness and sagaci...

A Mathematical model for the two phase flow of blood in a narrow capillary surrounded by the tissue has been presented in this paper. We have developed the earlier two phase models of blood flow in capillaries into a model of capillary-tissue fluid exchange system by including porous tissue enclosing the capillary. Blood is not a homogeneous fluid, It is a suspension. The suspended blood cells ...

The propagation of cracks in layered glass from low-velocity impact of sharp or spherical tip projectiles is observed using high-speed photography. Tests are also carried out to determine the threshold impact energy for chipping in glass blocks and subsurface crack instability in an edge-supported glass plates. The results identify the median and subsurface radial crack systems as the prime dam...

The boundary layer receptivity process due to the interaction of threedimensional slow and fast acoustic disturbances with a blunted flat plate is numerically investigated at a free stream Mach number of 3.5 and at a high Reynolds number of 106/inch. The computations are performed with and without two-dimensional isolated roughness element located near the leading edge. Both the steady and unst...

Scour around non-circular cylinders has seldom been studied before. This paper aims to numerically investigate the flow behaviour and evolution of local scour two single square-shaped piers with 90 ° (square pier) 45 (diamond orientation angles under steady-current live-bed conditions. For this purpose, a coupled approach between hydrodynamic morphodynamic model is developed validated against e...

This article reviews the hypersonic laminar-turbulent boundary layer transition over a blunt circular cone under support of National Key Research and Development Program China (contract No. 2016YFA0401200). Various approaches, including theoretical, numerical, experimental flight test, are combined to obtain complete perspective process as well some fundamental issues for this kind flow. The in...

This study carries out spatial-resolved optical birefringence observations to quantify, for mode I (tensile opening) loading, the stress intensification at crack tip of brittle and ductile glassy polymers (polymethyl methacrylate—PMMA, polyethylene terephthalate—PET) as well one type elastomer: (ethylene propylene diene monomer—EPDM). We measure buildup in a precut specimen by correlating retar...

the khushab anticline is located in the zagros fold-thrust belt in the lurestan. this anticline is affected by the balarud fault zone, which is a part of mountain front fault between the lurestan and dezful embayment zones. based on the measurement of the elements of fold style, this anticline is analyzed. according to these measurements, this anticline is a noncylindrical, asymmetrical and dis...
