Mechanics of a marine midge water locomotion

The Physics of Fluids
Marine midges, tiny insects with a body size of 2 mm and a weight of 0.07 dyn, provide valuable insights into advanced locomotion techniques. Found in shallow reefs at Wanlitong, Kenting National Park, Taiwan, these midges can continuously traverse ...

Fluid shear stress induces the phosphorylation of small heat shock proteins in vascular endothelial cells.

American Journal of Physiology, 1996
The small molecular mass heat shock protein of 27 kDa (HSP27) has been shown to influence actin filament dynamics and endothelial cell behavior in ways similar to those observed during laminar flow. We have employed human umbilical vein endothelial cells

Dynamics of turbulence strongly influenced by buoyancy

, 2003
The dynamics of quasi-horizontal motions in a stably stratified fluid have been simulated for Froude numbers of order 1, so that the flows are strongly affected by the stable density stratification, and for a range of Reynolds numbers.

Role of p38 MAP kinase in endothelial cell alignment induced by fluid shear stress.

American Journal of Physiology. Heart and Circulatory Physiology, 2001
The p38/mitogen-activated protein (MAP) kinase-activated protein kinase 2 (MAPKAP kinase 2)/heat shock protein (HSP)25/27 pathway is thought to play a critical role in actin dynamics.
