The concentrations used ranged from 1 to 8 grs per hundred milliliters, the frequencies from 0,5 to 35 megacycles, the temperatures from-35°C to-10°C. A Twin T impedance bridge and a specially designed cell were used throughout the work. The critical frequencies and relaxation times ...

The hypothesis of the equivalent hydrodynamic sphere has been verified for these polystyrene fractions in different solvants; furthermore, the theories of Kirwood-Riseman and of Peterlin allow the interpretation of the factors ϕ and Ψ; finally, our results tend to show that the equivalent ...

Plate protection devices and wire gauzes are effective because the desappearance of the active centres on the walls prior to the branching reaction rather than because their cooling effect. Foreign ignition sources (sparks and hot wires) may be uneffective in certain circumstances which can be ...
The properties of two crystalline α-amylases obtained from two different strains of B. subtilis are described. The pH optima, stabilities, temperature coefficients, absorption spectra, sedimentation and electrophoretic mobilities have been determined for both enzymes and found to be identical....
Different properties of the complexes Me Y formed between the trivalent lanthanides and HEDTA have been studied: the solubilities at 20°C and 100°C, the degree of hydration and the temperature of dehydration. Extremely high solubility of certain complexes and other unexpected properties at high ...
