The helical flow leads to the redistribution of bed shear stress and roughness coefficient in open-channel bends, influencing transport sediment riverbed evolution process. To explore mechanisms underlying this redistribution, a 3D numerical simulation 180° sharp bend was performed by solving Reynolds-averaged Navier–Stokes (RANS) equations using Reynolds equation model (RSM) as anisotropic tur...

Use the Spur dike as one of the easiest ways to protect the costal of the river has always been of interest to River engineers.The aim of this study was numerical investigate, the effect of distance and angle of the spur dikes parameters  on the pattern of distribution of average velocity  and the location of maximum velocity position at a mild 90 degree bend. For this purpose used ANSYS CFX so...

• The correlation of molecular shape and conformations with the Ntb phase transitional properties was investigated. onset transition temperatures turned out to be very sensitive these structural features. Observed differences were attributed changes in bend, which is only difference among dimers. In view importance features, particularly curvature, that form basis for appearance stabilization t...

Lumbar side bending movements coupled with extension or flexion is a known low back pain (LBP) risk factor in certain groups, for example, athletes participating in sports such as hockey, tennis, gymnastics, rowing and cricket. Previous research has shown that sagittal spinal postures influence the degree of spinal rotation, with less rotation demonstrated at end of range extension and flexion....

We provide direct evidence that Bin/Amphiphysin/Rvs (BAR) family members bend the steady state membrane architecture of organelles in intact cells. In response to inducible BAR molecular actuators, organelles exhibit distinct changes to the orientation and degree of their membrane curvature. This rapidly inducible system may offer a mechanism by which to better understand the structure-function...
