Features of work conditions on small and medium business enterprises.

Physiologic and hygienic evaluation covered work conditions on small business enterprises of retail and minor wholesale trade. Major unfavorable occupational factor for minor retail seller of foods is work process hardiness (up to 85% of <>). This work affects the workers' state, with 100% reports of the health state changes by the end of the working day.

Health state of medical personnel in MRI- tomography offices.

The study covered health state of medical personnel exposed to magnetic field in MRI-tomography offices. Findings are changes in functioning of cardiovascular and central nervous systems in a personnel group working with tomographs, that prove tension of adaptation processes due to occupational factors.

[IDENTIFICATION OF RISK FACTORS IN THE PRODUCTION OF SYNTHETIC RUBBER].

There was performed the identification of risk factors at the production of synthetic rubbers, priority factor of them is chemical. Results of researches testify to need of continuous monitoring of exposure of chemicals on atmospheric air of the residential territory for the purpose of securance of hygienic and ecological safety of the city.

Laser-induced photopatterning of organic-inorganic TiO2-based hybrid materials with tunable interfacial electron transfer.

Hybrid organic-inorganic materials based on TiO(2) gels demonstrate high photosensitivity. Associated with their stable photochromic behavior, these make them suitable for laser-induced photopatterning. We show that the electronic coupling along the extended interface between the inorganic, TiO(2)-based gel, and the organic, poly(hydroxyethyl methacrylate) networks allows (i) a rapid scavenging of the photo-excited holes by the polymer, (ii) an efficient trapping of the photo-exited electrons as small polarons (Ti(3+)) that develop "dark" absorption continuum covering the spectral range from 350 nm (UV) to 2.

Chemical activity of photoinduced Ti3+ centers in titanium oxide gels.

We report on the chemical activity of trapped electrons in wet titanium oxide gels. These electrons are generated under the band gap irradiation of gels in the spectral range between 3.25 and 4.

Light-induced charge separation and storage in titanium oxide gels.

We report on the interaction of light with a particular class of media--wet gels, which in contrast to sols of nanoparticles possess a macroscopic bulk structure, and which differ from conventional solids by the existence of the internal liquid-solid interface. We show, taking an absorption cross section of trapped electrons from Safrany, Gao, and Rabani [J. Phys.

[Complex hygienic evaluation of drivers' work conditions].

Drivers' work is characterized by various occupational hazards--higher psychoemotional strain associated with risk of traffic accidents, unfavorable microclimate, dusty and polluted air, static physical load.
