An association of the level of personal anxiety with polymorphic variants of the gene encoding serotonin transporter (5-HTT) in 57 Russian residents of Siberia and 62 Tuvinians was studied. The 5-HTT gene polymorphic variants were determined be means of allele-specific PCR with DNA isolated from the blood of subjects as a matrix. The level of explicit anxiety was established by means of Spielberger–Khanin questionnaire; implicit anxiety was established by means of associative test. Indices of aggressiveness, impulsiveness, behavioral activation and inhibition systems (BAS and BIS) were additionally determined in each subject. The 5-HTT gene S-allele was significantly more frequently found in the Tuvinians, while the L allele was more common in Russians. The implicit and explicit anxiety levels were lower in carriers of the LL genotype than in carriers of the SS genotype; LS heterozygotes demonstrated intermediate values of anxiety. The sex and ethnicity factors were associated with the level of explicit (but not implicit) anxiety. Tuvinian men with the SS genotype demonstrated a low explicit anxiety level, while Russian men with this genotype demonstrated high anxiety level. No intergroup differences were found in women with the SS genotype. An association of 5-HTT gene polymorphic variants with BAS indices and an inclination to verbal aggression was also detected. The data can be interpreted as an index of differences in the direction of anxiety in different cultures. Theoretically, genetically highly anxious Tuvinian men are afraid to show fear, since manifestation of fear is condemned in their social environment. © 2015, Pleiades Publishing, Ltd. Source

Comparative silicate analysis data on the distribution of the main ash-forming elements of Kaa-Khem coals in fly ash and slag from the Kyzyl heat and power plant in 1989-2009 heating seasons are presented. The degree of binding of SO2 from industrial smoke emissions increased in this two-decade time interval. The distribution of six main ash-forming elements between slag and fly ash is uneven: silicon, iron, manganese, and sulfur are concentrated in the slag. Fly ash is enriched in aluminum, titanium, and unburned carbon. The concentrations of alkali metals and calcium in the slag and fly ash are almost the same. The low-sulfur ash-and-slag waste of the Kyzyl heat and power plant with high silicon, aluminum, iron, calcium, and unburned carbon contents can be recommended as a raw material in the production of building materials, wall ceramics, and porous fillers, for road building, etc. The ash dump is of practical interest in terms of the extraction of valuable ferromagnetic materials (magnetite and ferrosilicon) and aluminosilicate microspheres. © Allerton Press, Inc., 2012.

It is shown that fully sintered ceramic articles can be obtained on the basis of local feldspar-zeolite raw material. Materials with high strength and low water absorption were obtained by optimizing the batch composition. © 2016 Springer Science+Business Media New York Source
