The zeta sedimentation ratio (ZSR) capillary tube, is subjected to four is a measurement similar to the detercycles of dispersion and compaction. mination of the erythrocyte sedimenAt the conclusion of this process, the tation rate (ESR) but possesses sevaral hematocrit of the blood in the red advantages. It is unaffected by anemia cell-containing portion of the capillary and responds in a line...

background: corrosivity is one of the factors affecting the water quality. not controlling the chemical quality of water in the distribution network causes corrosion, sedimentation and economical and health damages. the aim of this study was to determine the drinking water corrosivity and sediment of kuhdasht, iran by using the corrosivity index. methods: in this study, 12 predetermined areas l...

We present the validation of a recent fractional mathematical model for erythrocyte sedimentation proposed by Sharma et al. \cite{GMR}. The model uses a Caputo fractional derivative to build a time fractional diffusion equation suitable to predict blood sedimentation rates. This validation was carried out by means of erythrocyte sedimentation tests in laboratory. Data on sedimentation rates (pe...

Abstract In human society, there is a demand for sustainable solutions water preservation and efficient treatment systems. An important reservoir road runoff defined as rainwater leaching from roads, loading micropollutants infiltrating the soil. We aimed to study this poorly understood feature using large-scale metabolomic analysis coupled with of soil physico-chemical properties molecular che...

Natural montmorillonite was modified with a quaternary ammonium compound, hexadecyltrimethylammonium (HDTMA). The sedimentation capabilities of unmodified and modified montmorillonites were then investigated. The sedimentation velocity of modified montmorillonites increased if the amounts of adsorbed HDTMA were from 0.3 to 1.0 times the cation exchange capacitity (CEC). It also emerged that the...

The effects of solvent compressibility on the sedimentation behavior of macromolecules as observed in analytical ultracentrifugation are examined. Expressions for the density and pressure distributions in the solution column are derived and combined with the finite element solution of the Lamm equation in inhomogeneous media to predict the macromolecular concentration distributions under differ...

1. The size of two bacterial lipases was studied by SDS/PAGE, sedimentation velocity and sedimentation equilibrium to test for possible self-association behaviour. 2. Mr values of selected lipases were obtained from SDS/PAGE and sedimentation-velocity measurements, together with an absolute determination by sedimentation equilibrium 3. The Mr values obtained in a variety of aqueous solvents ind...

BACKGROUND Tinnitus is the perception of hearing a sound for which there is no external acoustic source. It is often associated with sudden, temporary hearing loss and has a clear impact on a patient's quality of life. Despite numerous trials, there are no treatments that can be considered well established in terms of providing replicable long-term tinnitus reduction. Complementary and alternat...

The Waaler-Rose test (Waaler, 1940; Rose, Ragan, Pearce, and Lipman, 1948) has established itself as a laboratory procedure of limited value in the diagnosis of rheumatoid arthritis. With a few exceptions the workers who have used it find it to be positive in under 75 per cent. of cases of that disease. It is rarely positive in other conditions, except disseminated lupus erythematosus and hepat...
