Studies on Digitalis VI
T IS undisputed that the administration of digitalis to patients with many forms of congestive heart failure results in an improvement in both the clinical state and in the abnormal circulatory dynamics that are characteristic of heart failure.'-6 The effects of digitalis in subjects without heart failure are less well defined. Although some glycosides augment the contractile force of nonfailin...
متن کاملChromium (vi) Compounds
Chromium (VI), also known as hexavalent chromium, is the second most stable oxidation state of chromium. Rarely occurring naturally, most chromium (VI) compounds are manufactured (products or by-products). Chromium (VI) can be reduced to the more stable chromium (III) in the presence of reducing agents (e.g. iron) or oxidizable organic matter (OSHA, 2006). Selected chemical and physical propert...

متن کاملElectroreflectance of Iv-vi Compounds
Electric-field modulation considerably enhances structure in the reflectance of a solid. In addition to the greater sensitivity, the symmetry-breaking effect of the modulation parameter provides symmetry information useful in the identification of critical points. Interband transitions, excitonic excitations and interactions between carriers and lattice can, in principle, be evaluated in their ...
متن کاملTunneling in Iv-vi Compounds
Metal-insulator-IV-VI compound semiconductor tunnel junctions were formed for both single and polycrystalline semiconductor material. I-V and conductance characteristics were taken as a function of temperature, and magnetic field. The experimental results were interpreted in terms of a conventional tunneling theory, and yielded information on Fermi energies, band gaps, temperature dependence of...
