in this study, the concentrations of heavy metals (ca, zn, cu, fe, mn, ni) in thesediment of shavoor river in khuzestan province in iran has been investigated. after the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. to determine the geochemical phases of metals in sediment samples the 5-ste...
The dynamics of a flexible filament sedimenting in a viscous fluid are explored analytically and numerically. Compared with the well-studied case of sedimenting rigid rods, the introduction of filament compliance is shown to cause a significant alteration in the long-time sedimentation orientation and filament geometry. A model is developed by balancing viscous, elastic and gravitational forces...
Certain factors are common to the erythrocyte sedimentation rate and the plasma viscosity. Thus fibrinogen increases the erythrocyte sedimentation rate (Gram, 1921 ; Greisheimer, Johnson, and Ryan, 1929) and Hardwicke, Ricketts, and Squire (1950) found that a direct logarithmic relation exists between the erythrocyte sedimentation rate and the plasma fibrinogen concentration. Also fibrinogen ex...
Sedimentation–diffusion profiles and layered sedimentation of charged colloids at low ionic strength
The molecular weight of Escherichia coli beta-galactosidase was determined in 6m- and 8m-guanidine hydrochloride by meniscus-depletion sedimentation equilibrium, sedimentation velocity and viscosity. Sedimentation equilibrium revealed heterogeneity with the smallest component having a molecular weight of about 50000. At lower speeds, the apparent weight-average molecular weight is about 80000. ...
Asaluyeh Fishery Port is an old fishery port located in the south-east of the Bushehr Province. The rapid shoreline advancement of the updrift fillet of the main breakwater during past few years and the sedimentation at the port entrance has resulted to substantial difficulties in using the port. The relatively large amount of sedimentation finally affected the navigation at the entrance of the...
To study grain quality traits and their relationships with high molecular weight (HMW) and low moleculor weight (LMW) glutenin subunits, 104 durum wheat genotypes were used. Six grain quality characteristics comprising wet and dry gluten content, test weight, grain hardiness, protein content and SDS sedimentation volume were studied. HMW and LMW glutenin subunits were evaluated using SDS-polyac...
The variation and path coefficient analysis of bread-making quality traits have been studied for 145 genotypes of breeding lines, cultivars and landrace varieties of wheat (Triticum aestivum L.). Bread-making quality traits of genotypes was evaluated indirectly by protein percentage, SDS and Zeleny sedimentation tests, hardness index, test weight, bread volume, grain moisture, and water absorpt...
In order to study the effect of traits related to baking quality of bread wheat, an experiment was carried out by six bread wheat genotypes (as parents) and their15 F1progeny using randomized complete block design with three replications in Kermanshah, Iran during crop season 2010- 2011. In this study 14 traits attributes baking quality bread wheat were evaluated. The analysis of variance was i...
Background & Aim:The main aim of this study was stabilizing D. Sophia beverage and reduce its sedimentation rate. Experimental: Xanthan and Carboxy methyl cellulose gums have been used in three levels (0.05, .01 and .02 gr/lit) and mixture of Guar-xanthan and carboxymethyl cellulose (each .1 g/l) and extracted dried gum from D. Sophia in (1, 2 an...
