The review gives some characteristics and methods of determination of microbiological damages of materials (adhesion, growing of microbe cells and changing of material properties under the action of microorganisms). These methods and characteristics give quantitative estimation of damages process. Authors of paper gave new method of microbiological damages investigation. This investigation is including several microbiological, chemical, biochemical and mechanical methods. It was shown that this complex of methods are very effective in case of investigation of material samples damages.

Are obtained the experimental dependences of the pressure of the saturated vapor on the temperature for the clean of dimethylsulfoxide and perfluorinebenzene in the range of temperatures, that corresponds to extractive rectification under the atmospheric pressure.
42-46 117
The new technique of contact crystallization with using of cooled solvent has been proposed and theoretically analyzed. This technique allows to exclude contamination of separated products by coolants and to simplify its instrumentation.
47-54 187
The questions of Distillation Process and Reactive Distillation Process into inert stream are considered.

Optimization of power supply level of a two-unit rectification column on preproject stage of development unit of division indissolubly is connected to used process computation variant, which the certain set of explanatory variables answers. In clause production of entropy is considered as criterion of an optimal arrangement of power supply at rectification of binary mixes various nature. The analysis of entropy production is carried out at design and verifying variants.

Synthesis of 1,2-di-(11,13-tetradecadienoyl)-sn-glycero-3-phosphocholine and 1,2-di- (2,4-hexadienoyl)-sn-glycero-3-phosphocholine, containing terminal polymerizable diene groups has been carried out. It is supposed that using of synthesized phosphorlipids mixtures followed by their polymerization will lead to formation of stable nanoparticles – bicelles, which will be capable to exist in a wide range of concentration of mixed components and resistant to organic solvents action.

The complex oxidative processes taking place in fat-containing products – pastes – during storage are defined by their multiple compositions. Secondary products of oxidation determined by the standard chemical method from the acid number value of the fat can react with various organic substances of pastes. Character of oxidative processes essentially depends on a state of foodstuff as heterogeneous disperse system.

This article is devoted method of synthesis and study of the properties of (±)-trans-2- dialkylaminoethylaminocyclohexahols. It was found that the studied compounds are not toxic and have expressed antiarrhythmic properties. It was found that the explored compounds are low-toxicity substances having pronounced antiarrhythmic properties.
