On diffusion of smoking components of smoke-air mixture (produced by IR smoke generator) in production of half-smoked fish
The technology of half-smoked fish fillets production using smoke-air mixture produced by IR smoke generator has been developed. It has been determined that depositing a pellicle of natural biopolymer on surface of the fillet before smoking permits to decrease the loss of semi-finished product's mass during smoking, make better organoleptic properties and increase the edibility term. The mathematical model of technological process has been developed; on the base of the model optimal values of main parameters have been determined. The draft of technical documents has been developed: specification of finished products, technological instructions and others. The edibility term of the finished products on the base of microbiological sample's researches during storage has been hygienically justified according to the requirement conditions. The mathematical model of diffusion process gives preliminary information about length of diffusion during smoking up to adjusted level of smokiness, which correlates virtually with all smoking technological effects (formation of flavour, antioxidation, antibactericidal effects).

On hydrocarbon degradation rate of petroleum hydrocarbons in the Kola Bay
The paper considers the dynamics of tissue biochemical parameters of fish family Salmonidae during storage under low temperatures. The complex analysis of biochemical parameters' dynamics accounting the peculiarities of chemical content and biochemical characteristics of fish is of great importance.

Distribution and potential activity of hydrocarbon-oxidizing bacteria in the water of the middle and northern tribes of the Kola Bay
The paper presents data on the number and distribution of microorganisms in the surface layer of water of the Kola Bay in the Barents Sea. The works were carried out in the Kola Bay in three stations located in the middle and northern tribes of the bay. The total number of microorganisms by direct account, the number of hydrocarbon-oxidizing bacteria and their activity have been investigated. The number of hydrocarbon-oxidizing bacteria depending on the season ranged from several dozen to several thousand cells in 1 ml of seawater. The natural salinity (PEMokt) hydrocarbons measured in water samples at temperatures in situ using 14C-octadecane as a substrate in the waters of the Kola Bay ranged from 0.069 to 0.134 mcg/(l*h). According to the calculations for a day on average of no more than one quarter of present hydrocarbons is oxidized by microorganisms in the water of the medium and northern tribes of the Kola Bay.

Laboratory diagnostics of chromosomal pathology in Murmansk and the Murmansk region (2006-2011)
The optimum method of chromosomal analysis of chorionic villus cells (placenta) in the diagnostics of chromosomal congenital and hereditary diseases has been defined. It has been stated that compulsory genetic consultation should be included in the complex of surveys to help improve the efficiency of the prenatal diagnostics. On the basis of statistical data the maximum value of chromosomal abnormalities constituting 8.3 % in 2011 as well as their overall percentage (3.8 %) in the last six years have been revealed. The growth of polymorphism (1.03 %) and translocation (0.5 %) has been observed. The chromosomal abnormalities have been revealed more (5.1 %) at the stage of embryonic development than at the stage of postnatal development. This proves the importance of prevention of hereditary diseases and timeliness of genetic consultation.
