Nine studies inform western scientists about some Russian thinking in the two fields these days. The topics include differential mutual diffusion coefficients of electrolytes measured by an open-ended conductimetric capillary cell, the relationship between thermodynamical parameters of activated complexes and initial reactants in the reaction of peroxides with amines, and the kinetics of growth of the bacterial strain Rhodococcus luteus Ac-1163 on different substrate. The English ranges from very good to incomprehensible.
