Research opportunities termoperlit thermal insulation product based on obsidian-perilit rocks
The article presents the results of research opportunities termoperlit based on sand-obsidian rocks perilit Tashkesken field using as a binder combined ligament (lime and caustic soda), sodium hydroxide and sodium silicate. Found that termoperlit on a combined bond does not meet the requirements of GOST. Termoperlit using sodium hydroxide as the binder fulfills the requirements of GOST thermal conductivity and volumetric weight, but not tested for durability. Termoperlit based on liquid glass meets the requirements of GOST in all respects.

Physico-chemical condition of uranium in mine waters bearing uranium and in sandy-loam grounds
Uranium state investigation results in sandy-loam grounds are provided in this work. In accordance with collected data, ion-exchange, complex-formation, hydrolysis, and oxidation-reduction processes are critical for uranium immobilization in sandy-loam grounds. Elements’ initial chemical form and micro-components presence impact on sorption behavior of uranium from technical sources.

Influence of drought and salinity on the antioxidant system of chloroplast of potato regenerants
This article shows that stress factors (salinity, drought) in varying degrees are depending from plant’s genotypes. The stress factors disturb the equilibrium of lipid peroxidation (POL) and the activity of the enzyme Superoxidedismutase in the potato’s chloroplasts. Also was shown, that prooxidants-antioxidants balance in the salt-tolerant genotype shifts to antioxidants, but in the sensitive genotype toward to prooxidants.

Key words: засоление; засуха; прооксиданты; антиоксиданты; АФК; СОД; ПОЛ; генотипы картофеля; drought; salinity; prooxidants; antioxidants; SOD; POL; potatoes regenerants.

Peculiarities of skin cancer a rising from scars
Follow-up and treatment results of 57 patients with skin cancer arising from scars are presented in the work. We show the peculiarities of treatment and morphological structure of the skin cancer arising from scars,its more aggressive character in comparison with the cancer which has developed in unchanged skin or owing to other reasons is established. Surgical and, combined treatment results of skin cancer arising from scars are discussed.
