Studies on the Interaction of Guar Gum with Chalcopyrite
Adsorption, electrokinetic and flotation studies have been carried out to investigate the interaction of guar gum with chalcopyrite. The adsorption density of guar gum onto chalcopyrite shows a weak adsorption maximum at pH 9.5. The adsorption isotherms exhibit Langmuirian behaviour. The electrophoretic mobilities of chalcopyrite are decreased in proportion to the added concentration of guar gu...
متن کاملPharmacological studies on fatigue. I.
Considerable investigation has been done as to whether or not a particular drug is effective for recovery of an animal after it has become exhausted. Experiments have included screening antifatigue effect on animals, but applications have not been generally established. Effects of drugs on psychological fatigue as seen in man can hardly be inferred from tests on animals. Even physiological effe...
متن کاملThree-dimensional topological insulators in I-III-VI2 and II-IV-V2 chalcopyrite semiconductors.
Using first-principles calculations within density functional theory, we investigate the band topology of ternary chalcopyrites of composition I-III-VI2 and II-IV-V2. By exploiting adiabatic continuity of their band structures to the binary 3D-HgTe, combined with direct evaluation of the Z2 topological invariant, we show that a large number of chalcopyrites can realize the topological insulatin...
متن کاملStudies on Mexican Typhus Fever. I
The preceding studies on typhus fever, chiefly done with a Mexican strain obtained from Dr. Mooser, concern themselves largely with reinvestigations of some of the fundamental problems of this disease. Filtration experiments carried out with methods almost regularly successful with true filterable viruses, in regard to material, suspension fluid, reaction, nature of filters and pressure employe...
