The paper describes basic principles related to weightlessness simulation. In ground-based experiments zero-g is simulated with respect to the conceptual mechanisms of weightlessness effects on the body. The main components of the effects are considered to be elimination of deformations and fluid redistribution. The paper surveys and summarizes different(More)
Studies of tissue bioenergetics are very important to gain insight into the effects of weightlessness on the animal and human body. A reduction of the muscular load in zero gravity should affect reactions of biological oxidation because their pattern and level are related to energy requirements of the body.

A new convenient method for the preparation of heterocyclic bis-adducts: of imidazole, benzimidazole, uracile with 1,1,1-trifluoro-2-bromo-2-chloroethane is described. The reactions are catalysed by the 18-crown-6-complex. The critical toxicity and antitumour activity of saprophytic strains Bacillus genus (B. subtilis 668 IMV and B. polymyxa 102 KSU)(More)
