Erythrocyte concentration distribution in sheathed microfluidic flows.

30 Aug 2009 The combined effect of dissociative and associative forces on erythrocytes flowing in direct, layered contact with cell-free "sheath" flows in microfluidic systems was studied to aid in the design of blood purification devices. A blood stream flowed ... Read more...

The deformation behavior of multiple red blood cells in a capillary vessel.

29 Jun 2009 The deformation of multiple red blood cells in a capillary flow was studied numerically. The immersed boundary method was used for the fluid red blood cells interaction. The membrane of the red blood cell was modeled as a hyperelastic thin shell. ... Read more...

Impact of shear rate modulation on vascular function in humans.

20 Jun 2009 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 ... Read more...

Technical information about 'Shear Strength'

Definition: The internal resistance of a material to moving some parts of it parallel to a fixed plane, in contrast to stretching (TENSILE STRENGTH) or compression (COMPRESSIVE STRENGTH). Ionic crystals are brittle because, when subjected to shear, ions of the same charge are brought next to each other, which causes repulsion.
