  • Accurate calculation of current-induced bed shear stress depends on probe height and wave conditions. (usgs.gov)
  • Also, an asymmetric failure propagation pattern could be obtained depending on an interaction between the W/H ratio, seam dip, in situ stresses, and pillar geometry. (cdc.gov)
  • These stresses arise when the radial pressure distribution is nonuniform due, primarily, to variations in gap bulk density (GBD ) of intumescent mat around the perimeter of the substrate. (sae.org)

  • The scrambled control was consistent with shear worry increasing TRAIL-mediated apoptosis having a cell viability of 50.six (Fig. 1c). (achrinhibitor.com)
  • There was no sizeable raise in viability among the siPiezo1 cells taken care of with TRAIL and shear anxiety on the scrambled cells with TRAIL and shear worry (Fig. 1c). (achrinhibitor.com)
  • SiPiezo1 cells handled with shear worry showed a reduced cell viability comparable on the siPiezo1 cells treated with TRAIL and shear worry (Fig. 1c). (achrinhibitor.com)
  • This suggests the diminished cell viability from the siPiezo1 PC3 cells, when treated with shear pressure and with TRAIL, is because of shear anxiety. (achrinhibitor.com)
