Zeta sedimentation ratio (ZSR) is a simple, rapid and reproducible test which is not influenced by variables like sex and anemia. There is good correlation with Westergren erythrocyte sedimentation ratio (ESR) in normal and hospital population. Limitation of packing force affects the use of the procedure in polycythemia and in patients with ZSR greater than 80%.

Presence of salts in water has been one of the biggest problems of industrial equipment such as evaporators, boilers, and pipes. These salts gradually form scales on evaporators and boilers tubes and reduce their efficiency. Pretreatment processes are conducted to remove these salts; with sedimentation tanks being one of the essential equipment used in these processes. This study numerically si...

Forest soils are shaped by various processes, like runoff, erosion, sedimentation and bioturbation. A better understanding of the interactions between abiotic biotic soil-forming including wild boar (Sus scrofa) rooting (i.e., subsurface foraging), enhances adequate management forest ecosystems. We hypothesized that intense soil influences occurrence boars modify outcome process redistributing ...

Pre-sedimentation basins are among the most important elements of the conventional water treatment process. In pre-sedimentation basins, due to different velocity gradients, secondary and rotational flows are formed that will create short paths and increase dead and still flow zones as well as changes in the flow mixing. This will prevent laminar flow conditions for sedimentation and will reduc...

Studies have been made by means of sedimentation in the ultracentrifuge, and by diffusion and electrophoresis, to determine the molecular weights and homogeneity of the tuberculin protein and polysaccharide molecules as found in their natural state in the unchanged filtrates from culture media after growth of tubercle bacilli. These results have been compared with data obtained on fractions iso...

ponding of unsaturated soils and the final resulted redox conditions, cause different chemical and electrochemical changes. redox potential is one of the most effective factors in determination of chemical properties of ponded soils; as by influencing dissolution and sedimentation of minerals and the activity and uptake of soil nutrients. the study site with an extension area of area about 10 h...

in carbonate systems, dolomites often form the best reservoirs .the dolomitized part of dalan(upper permian) and kangan(lower triassic) formations makes up the essential part of gas reservoirs in the south of iran. the dalan and kangan formations were dolomitized to various degrees in the areas of south of iran and- persian gulf.in most cases, dolomitization enhanced porosity and permeability o...

A modified procedure for purification of the adenosine 3’,5’-monophosphate-dependent (cyclic AMP-dependent) protein kinase from rabbit skeletal muscle is described. This procedure results in the separation of the enzyme into two peaks of activity on diethylaminoethylcellulose. No interconversion of these two peaks was observed. Both peaks exhibit dependence on cyclic AMP, but under certain cond...
