Climate systems: simulation of air influence on human organism

It is the fifth part from a series of articles about influence of climate systems on human organism using the method of crystallization in gels. Mathematical modelling and experimental data for crystalls growth in gels are given. It is shown that similar processes take place in human organism when polluted air come into it.

ANALYSIS
Гуминовые вещества как фактор риска для подземных сооружений

E.V. Abakumov, D.U. Vlasov, S.A. Starcev
Humic substances as risk factor for underground structures

Ways of influence of underground microflora and humic substances on underground building structures are analysed. Experimental data for soil samples are given. Soil samples were taken from metro tunnel in the time of its technic inspection. The classification for biological aggression of soils is proposed. On basis of this classification the research was conducted in the place of future inclined tunnels for projectible branch of underground railway.

MATERIALS
Использование материалов из гидролизованных алюмосиликатов глинистых пород для гидроизоляции зданий и сооружений

M.V. Knatko, E.V. Scherbakova, M.N. Ephimenko
Hydrolyzed aluminosilicates of mudstones. Application for building waterproofing

In the article the waterproofing technology is described. It is the alternative and in the same time the heir of traditional method "clay lock". New materials on basis of hydrolyzed aluminosilicates of mudstones have the same principle of work, but avoid a lot of disadvantages of traditional method. Results of material tests for principal physicomechanical properties are given in the article.
