Granular solid hydrodynamics (GSH) is a continuum-mechanical theory for granular media, whose wide range of applicability is shown in this paper. Simple, frequently analytic solutions are related to classic observations at different shear rates, including: i) static stress distribution, clogging; ii) elasto-plastic motion: loading and unloading, approach to the critical state, angle of stabilit...

The functional consequences of the differences in lipid composition and structure between the two leaflets ofthe plasma membrane were investigated. Fluorescence of 1,6-diphenylhexa1,3,5-triene (DPH), quenching, and differential polarized phase fluorimetry demonstrated selective fluidization by local anaesthetics of individual leaflets in isolated LM-cell plasma membranes. As measured by decreas...

in this paper, experimental data on the drying kinetics of corn in a packed and fluidized bed are presented. experimental research was conducted on a laboratory apparatus. corn was used as a material because of its significance in agriculture and the food industry. an analysis of the influence of the operational parameters (the drying medium velocity i. e. the fluidization number, the drying me...

BACKGROUND Cells resident in certain hollow organs are subjected routinely to large transient stretches, including every adherent cell resident in lungs, heart, great vessels, gut, and bladder. We have shown recently that in response to a transient stretch the adherent eukaryotic cell promptly fluidizes and then gradually resolidifies, but mechanism is not yet understood. PRINCIPAL FINDINGS I...

This study addresses the need to model bubble flow in a fluidized bed using probabilistic approach, which includes intrinsic randomness. It is shown that proposed predictive (PPM) overcomes limitations of deterministic correlations, commonly used describe dynamics high-density (above 2000 kg/m3) sand-beds Type B particles Geldart classification. proven PPM can relationship between axial chord a...

The fluidization of short Hi Nicalon S fibers was investigated before considering CVD coatings with controlled composition and thicknesses. a fiber batch alone being delicate not reproducible, the study consisted in comparing hydrodynamic behavior powder alone, to that fiber/powder mixture. particle beds studied by following their pressure drop as function temperature. minimum velocity (Umf) ev...

Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, its diameter remains approximately constant. The center of mass of the bubble increases with t...
