Dubishchuk M.M.Efficiency evaluation of the modern methods of fishing conditions forecasting in the Central-Eastern Atlantic (Abstract)
The issues of evaluating the quality of new commercial forecasting methods based on the environment satellite-based measurement data are considered in the article. The forecasts of fishing conditions prepared for the fishing industry enterprises within the period preliminary to new methods introduction (2009), and within the period of their usage (2013) were used. The success rate is used as the measure of forecasting ef-fectiveness, as the measure of adequacy the predicted and really recorded values. On the basis of the given forecasts with the results of real commercial fishery activities the evaluation of the forecast effectiveness prepared according to new and previously used methods of forecasting is made. Main economical and administrative factors influencing sufficiently on estimating the forecast success rate in modern conditions are presented. The conclusion about the effectiveness of using new forecasting methods is made on the basis of the received estimation of the forecast success rate. New approaches to forecasting demonstrate increasing the forecast success rate on the average by 10% and en-sure a more stable level of the forecast success rate as a whole.

Sokolov A.N., Chubarenko B.V.Sensitivity analysis for wave regime in wave deformation zone in the South-Eastern Baltic in a view of possible climate changes (Abstract)
The two-dimensional spectral numerical model was used for a simulation of wind waves. The modeling domain included the central part of the Baltic Proper, all boundaries were closed. Wind uniform in space and varying in time was the only forcing in the model. The correlation coefficient higher than 0.8 was obtained by the previously made model calibration versus field measurements of waves conducted at the Lubiatowo field station in 2006. The task of the study was to simulate the influence of a possible cli-mate changes on wave parameters in the nearshore zone of the Kaliningrad region. Four scenarios for the background sea level in the modeling domain were used to simulate wave fields in the nearshore zone (0-10 m of depth) under the real wind forcing, which took place during the storm on 12-14 January 2012: nowadays level, +50…+200 cm, according to different possible climate change scenarios. The results of the simulations showed that wave parameters seaward the first wave breaker and in the area between the shoreline and the last wave breaker are almost the same in all used scenarios and depend on the local wa-ter depth only. At the same time, the width of the wave transformation zone for scenarios of higher water level became narrow in 1.5-2 times in comparison with nowadays conditions. Narrowing of the wave transformation zone leads to increasing of the longshore current speed. This fact is very likely leads to increasing of the bottom erosion and the integral sediment transport.

Pylenok M.A., Mezenova O.Ya.Technology of rolls with atlantic herring and chitosan (Abstract)
In the article “The technology of the high biological value rolls using Atlantic herring and chitosan” the segment of the gastronomy, namely Japanese, and the variant of expanding the assortment and adaptation of the receipt to native raw materials are considered. Rolls produced with the standard receipt have a number of disadvantages, namely short expiry date, they don’t have a functional orientation, have a fragile con-sistency, and also there’s a necessity of substituting utilized salmon in the roll stuff. These disadvantages are eliminated by introducing chitosan into the receipt and also by enriching rice with ground kelp and using Atlantic herring as a stuff. The chemical con-sistency of stuff used in the receipt of rolls is analized: the comparison of herring and salmon chemical consistencies. The advantages of chitosan while its usage in the receipt as a biologically active stuff, preserving and structure-forming agent are presented. In the article the relevance of the Japanese cuisine in Kaliningrad region is shown. The technology of "Marianna" rolls production containing Atlantic herring, round grain rice, laminaria, apple vinegar, sugar, salt and chitosan is developed. The receipt of rolls is developed, the vitaminic, mineral and chemical content of the finished product is stud-ied. The recommendations of using the product are offered.

Lyubimov V.Yu.,Kreslavski V.D., Shirshikova G.N., Kosobryukhov A.A.Regulation of prooxidant-antioxidant potential by irradiation of plant leaves with phytocrome-activating light (Abstract)
In green leaves of plants, in addition to a number of others, two signal-regulatory systems operate – light-dependent phytochromic and oxidative – operating, first of all, on the basis of the ROS. The latter of them, depending on the absolute value of the pool of O2- and H2O2 and its dynamics, can also run the oxidative metabolism of carbon compounds and synthesis enzymes of the antioxidant defense. In this work, in experiments on seedlings of lettuce (Lactuca sativa L.) and arabidopsis (Arabidopsis thaliana, ecotype Columbia-0) we studied the possibility of the interaction between these two systems. It is shown that under the increasing dose of the RL from 0,6 up to 3.6 kJ m-2 a slight decrease in the activity of catalase and two-phase changes in the ac-tivity of general and ascorbate peroxidase occur. The dependence of H2O2 pool on RL-dose is mirrored in relation to the activity of peroxidase, and the participation in these processes of phytochrome-B is confirmed by the fact that FRL-irradiation significantly reduces the RL-induced change of prooxidant-antioxidant potential. UV-A irradiation of lettuce led to a twofold decrease of activity PS-2, probably as a result of the oxidative stress and the oxidative damage of photosystem membranes. Preillumination by RL sig-nificantly prevented this inhibition, possibly by reducing the oxidative stress on the pho-tosynthetic apparatus. The same was experimentally observed with the aid of the inte-gral process – photosynthetic CO2 assimilation. Moreover, the inhibition by UV and the protective role of phytochromic systems were found with the net assimilation of carbon dioxide only, but almost not touched on stomatal conductance. Thus, the obtained re-sults can be interpreted as the presence of regulation of prooxidant-antioxidant potential by the phytochromic system. This process significantly depends on the dose of RL-irradiation and, at the optimal dosage it is a mechanism that protects the photosynthetic apparatus against the damage from the oxidative stress.

Functional activity of mitochondria is important not only for the energy supply of cells, but also for maintaining the homeostasis, work of signaling pathways, activation and control of various types of the programmed cell death. The use of inhibitors of the electron transport chain (ETC) of mitochondria is a classic method for studying the functional activity of mitochondria as in vitro, and in vivo. Inhibition of complexes I and III of the ETC induced the dissipation of the mitochondrial transmembrane potential, the changes in the rate of respiration and morphological transformation of mitochondria with the formation of megamitochondria.

Kaznina N.M., Titov A.V., Batova Y.V., Laidinen G.F.The content of nonproteinthiols in SetariaViridis to cadmium action (Abstract)
In vegetation conditions the effect of cadmium (100 mcM) on the growth of green foxtail (Setaria viridis L. (Beauv.))and also on the content of non-protein thiols in root and leaf cells were studied. The concentration of metal in bodies of plants was defined. The researches revealed high resistance of a foxtail to cadmium, inhibiting the effect of metal concerning accumulation by plants of biomass wasn't observed, the stability index was equal 0.91. Thus the content of cadmium in plant organs was relatively high, and not only in a root, but also in a leaf. Plants resistance to metal provided by cellular detoxification mechanisms, in particular, the binding of toxic ions by non-protein thiols. We have found the decrease of the reduced glutathione (GSH) level and at the same time the sharp increase in the amount of phytochelatins. The most clearly changes marked in a leaf despite the minimal content of cadmium. It is assumed that the high level of the phytochelatins in the leaves is an important mechanism of plant tolerance to cadmium, with the protect of mesofyll cells from the toxic ions and allows to support work of the photosynthesis apparatus at a high level.

Blaginin V.A., Kazkekin I.E.The study of arc over-voltage based on the grounding arc stability analysis (Abstract)
The article presents the results of the grounding arc stability studies and its influence on the limit values of arc over-voltage. The studies can justify the border areas of application of arc over-voltage theories. The stability analysis performed by the method of Hurwitz has shown that the critical arc resistance increases with decreasing phase of the electrical system capacity. Increasing the critical arc resistance leads to the fact that its attenuation occurs after quenching of the free component of current single-phase circuit. Using the highest values of free amplitude component of the current single-phase circuit, the dependences of the limit values for the neutral displacement voltage of the constant potential of the network phase capacity, confirming the previously established experimental correlation between these variables were built.
