In order to increase the performance of a primary sedimentation tank (clarifier), it is essential to have a uniform and calm flow field. The use of suitable baffle configurations may help forming favorable flow field and increase the efficiency of the primary sedimentation tank. In order to find the proper position of a baffle in a rectangular primary sedimentation tank, computational investiga...

This unit introduces the basic principles and practice of sedimentation velocity analytical ultracentrifugation for the study of reversible protein interactions, such as the characterization of self-association, heterogeneous association, multi-protein complexes, binding stoichiometry, and the determination of association constants. The analytical tools described include sedimentation coefficie...

Distribution and elimination of petroleum products can be predicted in aerobic wastewater treatment plants (WWTPs) using models such as multimedia fate model SimpleTreat. An advantage the SimpleTreat is that it only requires a few basic properties chemical to calculate partitioning, biodegradation ultimately emissions air, surface water produced sludge. The structure reflects WWTP scheme. Howev...

investigation and preparing of wind erosion intensity maps are the main objectives of this research. in this research, the working unit map was prepared and then nine effective factors in wind erosion according to irifr.e.a model are determined at each of seven homogeneous units. according to the results, active sand dunes and landuse change showed the highest value with the rate of annual sedi...

In this study; membrane distillation technology using to associated oil water production desalination by air gap unit removed salt from the after separating product, via PTEF commercial hydrophobic with 0.22 µm porous and 0.011 m contact surface area, evaluated system operation parameter for feed effected on process employment under boiling point temperature that getting increments study energy...

A model for the emplacement, bioturbation, and preservation of fine scaled sedimentary strata has been used to evaluate the impact of interacting physical and biological sedimentary processes on preserved sedimentary fabric in three contrasting shelf and estuarine depositional settings: Eckernförde Bay, German Baltic Sea; the Eel Shelf, northern California, USA; and the northern Gulf of Alaska ...

The erythrocyte sedimentation rate (ESR) is still a widely used parameter for acute phase inflammation. Recently, new methods based on direct undiluted measurement of ESR in a standard EDTA tube have been developed. We evaluated the analytic performance of one of these new methods, the Ves-Matic Cube 200 (Diesse Diagnostica Senese, Siena, Italy), and compared it with several established Westerg...
