The article presents the results of mechanical activation steel-smelting slag affecting properties gypsum composition. As a result study, parameters were identified that characterize reactivity during activation. It was established increase in number Bronsted active adsorption centers on surface formed powders is responsible for their reactivity. However, maximum activity leads to large percent...

Fluorine-18 fluorodeoxyglu-cose positron emission tomography in mature T-cell and natural killer cell ma-lignancies. Recently in Blood, Schonthal and colleagues reported in an elegant study that green tea polyphenols interact directly with bortezomib and other boronic acid–based proteasome inhibitors and block their anticancer effects. 1 This subject has significant practice implications. By re...

A convenient and efficient direct protocol for the preparation of antibacterial azo dyes by the reaction of 2-naphthol with aromatic amines in the presence of catalytic amount of N-methyl-2-pyrrolidonium hydrogen sulfate ([H-NMP]HSO4) was carried out under solvent free conditions. This method has some advantages such as: easy work-up and easy separation of catalyst from the reaction mixture. Th...

A new approach is present for concentration effects on ionic reactions in solutions of small electrolyte concentrations. It is assumed that the mutual Coulomb interaction is felt by an ion pair only when their separation is smalller than the “Coulombic horizon”, R.,, namely when there is no intervening ion. This leads to an approximate but simple and parameterless, formula for activity coefftci...
