Biological testing of films for the closed ground with various physical properties // Tomsk State Pedagogical University Bulletin. 2000. Issue 2 (18). P. 70-73

The influence of the light correcting films of various compositions on vital activity of sprouts of cabbage was researched. For this purpose the technique of comparative trials was completed. The technique consists in cultivation of sprouts of cabbage in hothouses by a size 1x1x0,6 m, covered by different films with a control of plant's metrics. Is shown, that usage of films with various physical properties renders considerable influence on metrics index under them of cabbage's sprouts. The composition of the light correcting Alms permitting of cabbage's sprouts in a closed ground in locale of Western Siberia without padding heating and lighting and to reduce period of cultivation on 10-15 of days is defined.

Influence of Meteorological Conditions on Efficiency of Application of Corrective Light Films at Cultivation Plants in Conditions of Region of Tomsk // Tomsk State Pedagogical University Bulletin. 2003. Issue 4 (36). P. 39-44

On the example of cultivation of sprout cabbage of a kind «Nadezhda» in the summer period influencing of meteorological conditions 1999-2003 years to productivity of correction light films for protection closed soil is investigated. With usage of techniques of biological testing of films is rotined, that challenging influencing to growth and development of plants («polysvetany» effect) correction light films render only at enough favorable temperature and light meteorological conditions, giving considerable effects of increase of biomass of spout and economic productivity of horse radish. At a decrease of mean temperatures on 5-7 °C or increase of temperatures on 8-10 °C from optimum for cultivation of plants and long-term period of dense cloud cover during realization of experiment in conditions of closed soil without an auxiliary illumination and heating «polysvetany» effect is not watched. Reproduction of effect in region of risky agriculture (Tomsk) in the indicated term is reached 40% in most unfavorable for an agriculture spring period and 75 % in the summer period

Synthesis and Photochemical Dehydrocyclization of 1,2-Dyarifethenes // Tomsk State Pedagogical University Bulletin. 2003. Issue 4 (36). P. 45-49

The possibility of convenient preparative methods of synthesis of polycyclic aromatic hydrocarbons of foehn set by the way of arylating olefins with halogenarils in the presence of palladium salts and following photochemical dehydrocyclization of 1,2-dyarilethenes are explored. The conditions of receiving of 3, 4, 5-nuclear carbons with different position of substituents with good preparative outputs are found. The prospects of method for synthesis of hydrocarbons of foehn set is shown.

Research of Fluorescence, Provoked by Solar Radiation of Dispersed Photophosphors on the Basis of Connections of a Europium and Corrective Light Polyethylene Films with their Components // Tomsk State Pedagogical University Bulletin. 2004. Issue 6 (43). P. 40-45

The research of features of fluorescence of dispersed photosphors in conducted on the basis of organic and inorganic connections of a europium and polymer films with their components at excitation of solar radiation. The excitation of luminescence of phosphors by UV radiation of the sun does not change spectral content of luminescence radiation. For number of photophosphors on the basis of ocsysulfide of yttrium, activated with europium watches change of intensity of minor bands in luminescent spectrum concerning the principal band, that it is necessary to allow for consideration of photophysical characteristics of corrective light films with their components. The obtained data allow to conduct calculation of intensity of luminescence radiation under corrective light films with allowance for its spectral content

DEFINITION OF THE CONTRIBUTION OF LUMINESCENT RADIATION OF POLYETHYLENE FILMS WITH PHOTOLUMINOPHORS ON THE BASIS OF EUROPIUM COMPOUNDS IN AUGMENTATION OF PRODUCTIVITY OF PLANTS IN THE GREENHOUSES // Tomsk State Pedagogical University Bulletin. 2010. Issue 3 (93). P. 22-26

The article studied the influence of luminiscent radiation of photoluminescent films on augmentation of productivity of plants in a greenhouses, and also the reflected, absorbed and dissipated solar light photoluminophore particles in films. It is experimentally erected, that the basic contribution to augmentation of productivity of plants to a greenhouses under photoluminescent films imports the luminescent radiance generated by films. Productivity also is spotted by a relation getting on a plant direct and a diffused light.

RESEARCH OF PROPERTIES OF PHOTOLUMINESCENT FILMS AT EXCITATION BY A SOLAR RADIATION // Tomsk State Pedagogical University Bulletin. 2011. Issue 8 (110). P. 119-123

The fluorescen properties of polyethylene photoluminescent films connected with injecting to their composition of photoluminophor on the basis of linkings of europium in excitation of UV by radiation of the sun are investigated. For the first time experimental measurement of rates of fluorescent radiation of a photoluminescent film at its exploitation in natural conditions are carried out. The maximum values of fluorescence intensity of films in investigated conditions make near to 8 mW/m2, average day from 0.5 to 2 mW/m2. For the first time the received results have allowed to make a quantitative estimation of fluorescent radiation intensity of photoluminescent films at effective cultivation under them plants in natural conditions. Reproducing of such indices can allow transferring effect studying to controllable laboratory conditions.
