Anticoagulant therapy has been employed in thromboembolic disease with increasing frequency during the past few years. There has been a striking lack of unanimity in the literature (1 to 15) as to the effect of heparin or dicumarol per se upon the erythrocyte sedimentation rate. In view of the fact that anticoagulants are frequently employed in disorders in which the sedimentation rate is of im...

Analytical ultracentrifugation is one of the classical techniques for the study of protein interactions and protein self-association. Recent instrumental and computational developments have significantly enhanced this methodology. In this paper, new tools for the analysis of protein self-association by sedimentation velocity are developed, their statistical properties are examined, and consider...

Inorganic aluminum or iron salts have been used for many decades to coagulate colloidal particles in surface water prior to flocculation, sedimentation and/or filtration. Although effective, inorganic coagulants have several disadvantages including large chemical dosages required for treating eutrophic waters, large volumes of chemical sludge produced, and toxic effects of metallic coagulants o...

Because of the uniqueness geological mineralization, tailings obtained from Chenchao Iron Mine have low SiO2 content only 27.80%. Content Al2O3 and MgO is 13.31% CaSO4 22.09%. The fineness modulus ores large enough for convenient mineral separation, thus resulting in 16.03% −5 μm particles 27.76% −10 tailings, respectively. average particle size 69.36 μm; it belongs to category very fine tailin...
