The positioning of associated entities by importance for the sustainable development of microregion is held. Stakeholder management strategy of the Tiligul liman zone is proposed.
The article is devoted to a comprehensive system of marine planning in general and in particular coastal seas. This paper analyzes the characteristics of marine planning, and causes existing complications, recommendations for its development and improvement.
The meaning of the institutional approaches to the development of environmental entrepreneurship is determined. The systematization of existing scientific forms of institutional approaches to the development is given. The institutional approaches to the development of environmental entrepreneurship in the recreational and touristic sphere are considered.
The approaches to higher quality wine production are considered in the article. The directions of wine production are defined. The system of the requirements to a wine quality and the regulations of a new wine classification are worked out.
On the basis of daily precipitation data sets from 28 hydrometeorological stations of Ukraine the seasonal and yearly extreme value rows are got for 1951 – 2009 using several independent methods. Their linear trends are estimated in this paper. The space distribution of climate change of extreme precipitation frequency over the Ukraine in winter, spring, summer and autumn is analyzed in the paper.
We study a spat–iotemporal variability for the features of droughts at the time scales 12, 24 months during 1951–1980 and 1981-2010 for Ukraine. It was found that the maximum number of long and severe droughts was registered in the period of global warming. It is also found a strong relationship between temporal variability of drought and an average annual flow of the Southern Bug River during 1951–2010.
The analysis with using the criteria of hydrodynamic instability for the cases of intensive cyclogenesis, related with cut-off low over territory of Ukraine in summer is presented.
Review of existing grain crop grow models of period from sowing to germination and the algorithm of developed dynamic model that describes the physiological and biochemical processes occurring in seeds during the period are discussed. The structure and the scheme of the model were described in details.
It was considered the possibility of applying Johnson’s distribution law for equalization series of wind speed at the ground surface with their annual and diurnal variations оn the marine hydrometeorological station Illichivsk- port.
Based on results of modelling of autotrophs responses to seasonal temperature variations, the role of temperature in formation of a scenario of cyclic successions of planktonic communities of the Barents Sea and the Black Sea is discussed. The quantity of bioproduction potential realization (μ/μm), taken as a conditional function, is used for the analysis. Discussed are causes of formation and effects of existence of the clear water phase in the Bogorov-Shirshov bimodal scenario of plankton development.
Generalizations of the real hydrometeorological and morphometric information is conducted for the aquatorium of the Kakhovka reservoir, comparison and analysis of results.
The paper presents the results of the assessment of water quality of the river Desna over a period of years and the years of typical water content based on calculations of water pollution index (WPI) and the environmental assessment of the quality of surface waters according to the relevant categories, determination of the suitability of water using for domestic water use.
In the article the norms of annual flow are summarized on territory of Zakarpat’ya.
On the basis of the modern source of information on the maximum spring flood runoff analyzed by trends in the changes of runoff characteristics and calculated the principal statistics of the time series of maximum water flow and layers of flow in the basin of the river Dniester.
The results of the calculations and analysis of three-dimensional wind-driven circulation of water at the water area of the Tiligul estuary under stationary winds of different directions are given. The calculations are performed using a hydrodynamic model Delft3D-FLOW on a curvilinear computational grid.
It was considered and analysed the sources and mechanisms of alluviums in the Kerch channel. A variety of alluviums and their feature, influence of natural and human factors, are brought. It is exposed mechanisms of formation of the self-weighted alluviums, their sources are described. It is meaningfulness of defined flow, waves and flow, winds and gales, dnedgiy works, and also anthropogenic and natural factors.
Basic topics of spintronics such as spin valve, interface resistance due to mode mismatch, spin potentials, non-local spin voltage, spin moment and its transport, Landau – Lifshitz – Gilbert equation, and explanation on its basis why a magnet has an “easy axis”, nanomagnet dynamics by spin current, polarizers and analyzers of spin current, diffusion equation for ballistic transport and current in terms of non-equllibrium potentials are discussed in the frame of the «bottom – up» approach of modern nanoelectronics.
By present paper we open the set of reviews concerned the study of structure and dynamic properties of nonequilibrium, dissipative, nonlinear systems – granular materials which has a wide applications in science and industry. The focus as it is planned will be done on overview of observed specific properties (like compaction, segregation, inelastic collapse, dynamic phase transitions and some other) and their physical modeling superimposed with the numerical simulations and in some cases with the direct physical experiments. The influence of inelasticity of the intergrain collisions, as well as initial and boundary effects and relevant constitutive relations will be also outlined. The present first part of review is related to outline of most specific properties which display granular materials subjected into particular conditions.
It is proposed a new approach to non-linear modeling and forecasting chaotic processes in geophysical and ecological systems, which is based on the conception of compact geometrical attractor and neural networks (artificial intellect) algorithms. In particular, the proposed approach can be used in a short-and middle-termed forecasting air pollutants concentration evolution in atmosphere of an industrial city.
The interaction of 1H-imidazole-4,5-dicarbonitrile, 3-nitro-1,2,4-triazole and 1H-tetrazole which containing one by one proton at two donor atoms and which parted by one covalent bond with crown – ethers of possibility synthesis a neutral crystal supramolecular compounds due to a proton donor properties of aromatic heterocyclic was exhibit.
