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...

Abstract Purpose Although the coordination between stomatal closure and aboveground hydraulics has extensively been studied, our understanding of impact belowground on regulation remains incomplete. Here, we investigated whether how water use maize ( Zea mays L.) varied under hydraulically contrasting soil textures. Our hypothesis is that a textural-specific drop in hydraulic conductivity assoc...

The sediment composition of the seabed governs its mobility, hence determining transport and morphological evolution estuaries tidal basins. Bed sediments often consist mixtures sand mud, with spatial gradients in sand/mud content. This study aims at increasing understanding processes driving basins, focusing on depositional processes. We show that bed Wadden Sea tend to be either mud-dominated...

this experiment was carried out to investigate the effect of different substrate on growth and yield of gerbera flower. the experiment was performed using 10 treatments as fallow: fine sand, peat +fine sand (%25+%75), peat + fine sand ( %50 +%50), perlite + peat (%75 + %25), perlite + peat (%50 + %50), perlite + peat (%25 + %75), perlite + peat + expanded clay (%25 + %70 + %5), perlite + peat +...

The accurate prediction of sand transport rates in the coastal zone depends not only upon the choice of sediment transport model but also, rather critically, upon the formulation used to predict the bed roughness (ks). Sand transport rates are modelled here using both a One-equation, turbulence-closure, TKE-model and also Bijker’s sand transport model. Following some remarks about the nature an...
