Effects of the shape properties of talc and quartz particles on the wettability based separation processes
(ELSEVIER SCIENCE BV, 2004)
Shape properties of talc and quartz particles ground by a laboratory size ball, rod, and autogenous mills were studied using scanning electron microscope (SEM). More than 100 particles were measured to do the shape analysis ...
Determination of Al(III) activation conditions for white bentonite used for cottonseed oil bleaching by robust design
(WILEY, 2006)
The optimum AI(III) activation conditions for white bentonite (Ordu, Turkey), used as a bleaching agent for cottonseed oil, were investigated. AICl(3) -clay suspension was hydrolyzed in situ using NaOH to investigate ...
Gypsum: An additive for stabilization of swelling clay soils
(ELSEVIER SCIENCE BV, 2009)
Low rise buildings are particularly vulnerable to ground movements sourced from swelling and shrinking of the expansive clay soils. Geotechnical engineers have long recognized that swelling of expansive clays caused by ...
Photo-degradation of some dyes using Ag-loaded titaniumdioxide
(KLUWER ACADEMIC PUBL, 2001)
The photocatalytic degradation of organic dyes using TiO2 and silver-loaded TiO2 has been studied. The dyes which were chosen (methyl violet, a cationic dye; Cibacron Blue FMR, a reactive dye; and Maxilon Red GRL, a mono ...
Impact of coronary collateral circulation on QT dispersion in patients with coronary artery disease
(LIPPINCOTT WILLIAMS & WILKINS, 2006)
Objective The aim of this study was to assess the effect of coronary collateral circulation (CCC) on QT dispersion (QTD) in coronary artery disease. Background A prolonged QTD has been linked to increased heterogeneity of ...
