Impact of hydrodynamics on oral biofilm strength.

29 Sep 2009 Mechanical removal of oral biofilms is ubiquitously accepted as the best way to prevent caries and periodontal diseases. Removal effectiveness strongly depends on biofilm strength. To investigate the influence of hydrodynamics on oral biofilm ... Read more...

Cyclic stretch induces cyclooxygenase-2 gene expression in vascular endothelial cells via activation of nuclear factor kappa-beta.

9 Sep 2009 Vascular endothelial cells respond to biomechanical forces, such as cyclic stretch and shear stress, by altering gene expression. Since endothelial-derived prostanoids, such as prostacyclin and thromboxane A(2), are key mediators of endothelial ... Read more...

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...

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.

Descriptor UI: D033081

Alternative terms: Shear Strength; Strength, Shear;

Allowable Qualifiers: drug effects; physiology; radiation effects;

Tree Number: G01.374.820;
