We present results of Brownian dynamics simulations of polymer brushes under steady and oscillatory shear. The brush is sheared by a bare surface and the resulting solvent velocity and polymer dynamics are solved self-consistently. Under steady shear the deformation of the brush proceeds in two steps: chains tilt in the flow direction followed by a physical thinning of the brush. The brusheffec...

It has been widely observed that atherosclerotic stenosis occurs at sites with complex hemodynamics, such as arteries with high curvature or bifurcations. These regions usually have very low or highly oscillatory wall shear stress (WSS). In the present study, 3D sinusoidally pulsatile blood flow through the models of internal carotid artery (ICA) with different geometries was investigated with ...

Submitted for the MAR15 Meeting of The American Physical Society Yielding of colloidal gels under steady and oscillatory shear GEORGE PETEKIDIS, ESMAEEL MOGHIMI, NICK KOUMAKIS, IESLFORTH, FORTH TEAM — The structural and rheological properties of intermediate volume fraction colloid polymer gels are examined during and after steady and oscillatory shear flow using rheometry, confocal microscopy,...

INTRODUCTION It is unknown if there are limb differences in vascular function during prolonged sitting. PURPOSE This study was designed to test whether the effects of prolonged sitting on brachial artery (BA) and the superficial femoral artery (SFA) are similar. METHODS Twelve men (24.2 ± 4 yrs.) participated in a 3 hr prolonged sitting trial (SIT). SFA and BA flow mediated dilation (FMD) a...
