The Electrical Conductivity of Molten Oxide-Fluoride Cryolite Mixtures.

A new way to reduce the energy consumption during the operation of powerful aluminum reduction cells is suggested via reducing the resistance of the electrolyte, i.e., increasing its electrical conductivity.

Electrochemical Production of Bismuth in the KCl-PbCl Melt.

An anode dissolution of binary metallic lead-bismuth alloys with different concentrations of components has been studied in the KCl-PbCl molten eutectic. The dissolution of lead is found to be a basic process for the alloys of Pb-Bi (59.3-40.

[Isolation of strains of the Hong Kong complex (H3N2) influenza virus from Nyctalus noctula bats in Kazakhstan].

Four antigenically related hemagglutinating agents were isolated from pools of lungs and tracheas of Nyctalus noctula bats in chick embryos. Identification of the isolates by the hemagglutination inhibition, neuraminidase activity inhibition and double immunodiffusion methods revealed close antigenic relationships with A/Port Chalmers/73 virus.

[Results of a study of some methods of differentiating M. pneumoniae strains by the virulence of the degree of attenuation].

Study of five M. pneumoniae strains by the intensity of hemolysis and hemadsorption demonstrated no definite differences between them. Experiments on Cricetus auratus W.
