PHOTOVOLTAIC EFFECT IN THE PHTHALOCYANINE AND PERYLENE ORGANIC JUNCTION LAYERS ^{[№ 12 ' 2011]}
Organic solar sell consisting from PTCDA donor and CuPc acceptor layers was formed. Its photophysical properties were investigated. It was shown that obtained multilayer system has nonlinear I-U dark characteristic and can induce photoelectromotive force jmax =0.6 V. On the base of the investigation of photoelectric cell spectral sensitivity its heterojunction efficient thickness was evaluated.

BIOLOGICAL PROTECTION OF CUCUMBERS AND TOMATOES OF PROTECTED SOIL FROM ROOT ROT ^{[№ 12 ' 2011]}
The effectiveness of a biological product Elena, Zh on cucumbers and tomatoes of protected soil is studied in Astrakhan region. It is shown that the biological product is active against root rot pathogens of greenhouse plants (biological efficiency to 73.08%). Growth stimulant drug effects on plant performance and confirmed by biometric data on the yield (yield increase compared to control up to 40.0%).

THE INFLUENCE OF ABIOTIC AND BIOTIC FACTORS ON THE IMMUNOLOGICAL RESPONSE OF FRESHWATER BIVALVES IN THE EXPERIMENT ^{[№ 12 ' 2011]}
Influence of chemical and biological factors on intensity of the immune answer of fresh-water folding mollusks is investigated. It is defined that the maximum immunological activity of mollusks is observed at joint influences of pollutants of the various nature.

IMMUNOLOGIC REACTION OF FRESHWATER BIVALVES FOR ADVERSE ENVIRONMENT EFFECT ^{[№ 6 ' 2010]}
The authors study effect of anthropogenic load of different degree of a basin on rate of immune response by freshwater bivalves. It has been determined that immunologic activity of bivalves directly depends on pollution of observable points: the higher pollution level, the higher immune response of the bivalves.
