the local solid flow structure of gas-solid bubbling fluidized bed was investigated to identify and characterize the particle clusters. extensive mathematical calculations were carried out using the energy-minimization multi-scale (emms) approach for evaluating cluster properties including the velocity, the size and the void fraction of clusters in the dense phase of the bed. the results showed...

We report numerical estimates of correlation lengths in 2D Potts models from the asymptotic decay of the cluster-diameter distribution. Using this observable we are able to verify theoretical predictions for the correlation length in the disordered phase at the transition point for q = 10, 15, and 20 with an accuracy of about 1% 2%. This is a considerable improvement over previous measurements ...

in order to assess and identify genetic diversity and genetic relationships of the 64 kabuli chickpeas genotypes, an experimental design was carried out in a simple lattice design (8×8) in 2009-2010 cropping season on the research field of college of agriculture and natural resource of tehran university. the results of phenotypic correlation showed that grain yield per plant had significant and...

in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...

to study yield and its components by the method of multivariate analysis, 25 genotypes of melon were sown on the basis of square lattice design of 2 replications in zahak agricultural research station. analysis of variance showed that there were significant differences among genotypes in some such characters as: fruit weight, width, and seed weight and yield. simple correlation coefficients sho...

Pd, Ag, Cd and Au clusters of varying sizes have been investigated by scanning tunneling spectroscopy under ultra-high vacuum. The conductance of the clusters decreases markedly when the cluster diameter is F1 nm. A plot of the density of 3 Ž . states at the Fermi level against the cluster volume varies nearly linearly up to a cluster volume of 4 nm diameter ;2 nm . Below a cluster diameter of ...
