A class of spatially localized solutions of Davey-Stewartson II equation is examined; it is shown that such solutions tend to lose the locality properties with time scale corresponding to a characteristic space scale of initial localization. The locality loss manifests itself with emergence of resonance spikes, whose total number is determined by the asymptotic behavior of support function on infinity. In particular, the exponentially localized perturbations split into an infinite number of the resonances.

|Yurov A.V.||One more observational consequence of many-worlds quantum theory (Abstract)|
Using new cosmological doomsday argument Page predicts that the maximal lifetime of de Sitter universe should be tmax = 1060 yr which is way too small in comparison with strings predictions (τ>googolplex). However, since this prediction is dependant on the total number of human observations, we show that Page arguments result instead in astounding conclusion that this number is the quantum variable and is therefore much greater then Page’s estimation. Identifying it with the number of coarse-grained histories in de Sitter universe we get the lifetime of the universe comparable with strings predictions. Moreover, it seems that this result can be considered as another one of the observational evidences of validity of the many-worlds quantum theory. Finally, we show that for the universe filled with phantom energy tmax ~ tf up to very high precision.

The method of the complete block decomposition is one of thepopularexact methods of solution of the systems of equations with block matriceswith belt structure. There are some conditions of existence of this method (e.g. [1-3]). In this article have been formulated andprovedmore general conditions of the existence of the complete block decomposition, that come to the testing of existence of the usual LU - decomposition of the Jacobi matrix, which elements are values of matrix norms for the blocks of the initial matrix of the system of equations.

|Pavlenko A.A., Nedostup A.A.||Mesh opening value in the net of different construction trawl codends (Abstract)|
In the present study, we attempted to determine the mesh opening value of trawl netting, depending on the number of net panels on the perimeter of its construction. To this end, we conducted two experiments to evaluate the opening of the mesh. One experiment was conduct in the sea and the second is a scale modeling one. Sea experiment was done by underwater video monitoring of the mesh opening value of eight and four net panels of the trawl. The findings showed that the mesh of eight panels part of trawl were opened more than four panels one. The scale model experiment allowed quantifying the degree of mesh opening for two panels trawl codend and for four panelscodend. So, in the conic part of two panelscodend the mesh opening was 41% less then in the four panels one. For the cylinder parts of model trawl codends the difference was 78%.

The equations of movement of trawl complex (at constant length of the towing warps and at arbitrary maneuver of trawler) based on its schematization by spatial two-warp mechanical model, are offered. With the help of numerical integration of obtained equations, the possibilities of outcome of trawl and trawl doors from tecnologically admissible regime at trawler's curvilinear movement, are investigated.

As a result of registration works in Peter the Great Bay (PGB) in 2009 is revealed, that the quantity of species most frequently meeting in catches, reaches 60. Total weight of these species makes 112,3 thousand tons. On a tentative estimation, the annual production of ground trawling in PGB can make 1,9 - 2,7 thousand tons, or 1,7 - 2,4 % from a general estimation of bioweight. Species structure of catches on trade vessels differs by the high contents Sclerocrangonsalebrosa and crabs (Kamchatka and Opilio), that can specify purposeful withdrawal of these species in commercial objectives. At the same time on trade vessels are thrown out practically all species Scorpaenidae, Сlupeidae, Rajidae, Liparidae, Stichaeidae, Zoarcidae, TrichodontidaeEngraulidae, Сottidae and also fishes and crabs of small size. The question about survival of fishes and crabs, which throw out for a board of a vessel, practically is not investigated.

The Presented results of the experimental work, in accordance with study of the problem of the slippage of the fishing gear (FG) on surfaces of the tractive drum of the mechanism of the friction type (MFT). The purpose of the called on studies - a determination of the influence to district velocity on surfaces of the drum on steady-state factor of friction in friction pair "FG-MFT". The district velocity created by drive MFT, is considered as velocity of exhibit shifting power, bring about friction of the slide (slipping) in friction pair. The Experiments are organized with friction pairs, formed cordage from polyamides and steel drum MFT. The District velocity on drum changed to account of management electric motor MFT at converter of the frequency. The Pull in running up branch of the cordage was measured by a strain gauge and registered by the tensostation. An analysis got data has shown the trend of the fall of the steady-state factor of friction when increase the district velocity on surfaces of the tractive drum MFT.
