The author dwells on the role functions of kaicha (narrator) in heroic legends of the Shorian people. The presence of kaicha in folklore works is determined not only by the narrator
This article is devoted to proverbs used as epic formulas in typical places of heroic legends of the Altai. In the study of Turkic language such theme is insufficiently explored. The author resorts to excerption and thorough analysis of the fund of proverbs of the Altaic epos. In this work, themes of proverbs, their presence in one or the other typical place, their syntactical structure, manners of modifying (lexico-grammatical and semantic), as well as parallels in epos of the other Turkic peoples are brought to light. Statement of the question about connection of the proverb
The article is devoted to the study of structural peculiarities of the Khakass myths. The questions connected with their formation and composition construction are touched upon. Such composition elements as beginnings and endings, as well as imitative and expressive means are revealed. Moreover, the place of each element in composition of the myths, as well as the extent of their stability and variability are shown. Tracing the evolution of the Khakass myths, the author draws to the conclusion that at the earliest stages of their development they were formed as short stories, the elementary ones in the content and structure. Meanwhile, myths of the later periods of formation are blessed with artistic form and clearly seen composition construction of their plots.

Perspective directions and results of the investigations of physicochemical transformations undergone by mineral and organic components of soil and natural water in the presence of heavy metal ions, which are among the most widespread pollutants of the biosphere, are considered. The mechanism of the indicated processes is discussed along with the effect of various factors on their kinetics (nature of heavy metals and substrate, pH of the medium, action of solar radiation, etc.).

A homopolymer of N,N'-bis(vinyloxyethyl)thiuramdisulphide was synthesized via cationic polymerization and investigated as a sorbent of the ions of mercury and precious metals. The effect of the nature and concentration of acid, phase contact time on the extraction of metals was revealed; sorption capacities of the polymer and metal partition coefficients were estimated. It was shown that the sorbent exhibits high sorption activity to metal ions in the cationic form: with respect to mercury (Hg2+) from 1 M HNO3 solution - 1100 mg/g, 1M H2SO4 - 990 mg/g, 1 M HCl - 280 mg/g; with respect to silver (Ag+) from 1 M HNO3 - 850 mg/g, from 1 M H2SO4 - 900 mg/g. A mechanism of the interaction of active groups of the sorbent with metal ions was proposed on the basis of IR spectroscopic data. The homopolymer of N,N'-bis(vinyloxyethyl)thiuramdisulphide sorbs mercury and silver ions selectively from a mixture of copper, nickel, iron and zinc salts. The possibility to use the sorbent for concentrating precious metals and for analytical purposes was demonstrated. A method of sorbent regeneration was developed.

Concentrations of 23 polycyclic aromatic hydrocarbons (PAH) were determined in the bottom sediments of the tributaries: the Selenga, the Turka, the Khaym, the Barguzin, which provide more than 70 % of the water drainage into the Baikal, and in the bottom sediments of the shallow water regions of the lake: the Zmeevaya bay (Chivyrkuy arm) and the Sor-Cherkalovo bay. It was discovered that the level of pollution with PAH is relatively low; the sum of PAH concentrations for the 23 individual compounds is within the range 1.4-5.2 mg/kg (for 5 compounds, the range is 0.15-1.11 mg/kg). The presence of PAH in the samples of bottom sediments is due to local sources of petrogenic and pyrolytic nature.

Chlorination of butyl rubber by molecular chlorine in solution relates to the class of fast chemical reactions. A new continuous method of obtaining chlorobutyl rubber in the industry is proposed on the basis of small-size tubular turbulent devices of the jet type; the method provides many ecological and technological advantages.
