Baranov D.A., Vlatskaya I.V. USING THE NETWORK DATABASE FOR STORING COMPLEX STRUCTURED DATA ON THE CLIENT IN AN INFORMATION SYSTEM WITH A WEB-INTERFACEThe development of Web 2.0 technologies has led to the displacement of complex applications on the Web. A Web-based applications have several advantages, however, the current limitation of the Webš2.0 platform (in particular, the lack of support for distributed object systems) do not allow to effectively handle complex structured data, which hampers the implementation of information systems in the form of web-based applications. The data with a complex structure (complex structured) include arrays, lists, trees, graphs, networks and combinations thereof. The problem is the complexity of the relevance maintenance of the web pages and synchronization with the server, the large amounts of data need to be transmitted, as this could adversely affect the reaction rate of the application user interface. Hence, an important task is to minimize the volume of transmitted data necessary to perform an operation and the elimination of reloading data. As a solution to this problem is proposed to introduce a separate (sub) level data on the client side. In the course of such a level of abstraction that solves the problems described above, it developed the concept of a unified oriented graph (UOG), which is a special case of the network database.Key words: distributed systems, object graph unified, complex structured data, databases.

Korabeynikov I.N., Korabeynikova O.A. SCIENTIFIC AND PRACTICAL ASPECTS OF FOOD SAFETY IN THE ORENBURG REGION BASIS OF CLUSTER APPROACHCurrently, under the food security is to understand the economic development of the territory, which will ensure the implementation process to ensure physical and economic access to every citizen of foods that meet the requirements of the Russian legislation on technical regulation. This modern authors formation and functioning of product clusters primarily examined from the standpoint of production approach. However, this approach does not fully reflect the various aspects of the practical implementation of a network of economic actors in the process of providing the population with food. The article highlights the need to provide a theoretical study of the problems of food security in the region, based on the cluster approach, which includes the provisions of the following theories: the cluster theory of economic development, the theory of stagnation and theories of regional development, defined by their characteristics. Based on the analysis of the practice of building clusters in the Russian grocery isolated model clustering product that have an orientation for the development of the relations of production and the development of food consumption. Clarification of theoretical and practical aspects of the product cluster formation has led to the possibility of clarifying the concepts of "food security" and "food cluster". According to the results of the research in the formulation of models of building product clusters and determine the content of mono-product polyproduct clusters and networks multicluster manifested in the differentiation of production and economic specialization and priorities of cluster development. It was determined that the priorities in the implementation of food consumer market organizations should reflect the need for the development of consumer markets for local producers. Clarification of the concepts of "food security" and "food cluster" allowed to determine the need to build regional production, logistics, service, trade and other systems in a variety of processes implemented to ensure food security.Key words: food security, food cluster model, typology, orientation, production, consumption.

Nosenko L.I., Gevorkyan T.V. THE CONCEPT OF DEVELOPMENT OF ALTERNATIVE MEANS OF RESOLVING LEGAL CONFLICTS IN THE ORENBURG REGION IN ORDER TO INCREASE THE LEGAL CULTURE OF THE POPULATIONThe lack of justice formed in the area of effective mechanisms of civil-legal regulation of alternative ways to protect the violated pravotritsatelno affects the confidence of civil turnover subjects to this form of implementation of the rights. Failure to understand the prerequisites, the nature and types of alternative ways to protect the violated rights does not give an opportunity to talk about the stability of the legal understanding of the importance of alternative procedures to resolve legal conflicts. In order to assist in the implementation of the citizens of the Orenburg region the right to effective legal protection, developed the concept of the development of alternative methods of dispute resolution, the implementation of which will serve as a mechanism for improving the legal culture of the population of the Orenburg region. Alternative methods of dispute resolution require active development due to the need to significantly improve the protection and preservation of the rights of citizens, which contributes to the formation of the rule of law. Orenburg region should be one of the most advanced regions, not only in the sphere of economic relations, but also in the development of the legal culture of the population. The fundamental problems due to the need of practical implementation and expansion of the scope of the institutions of the rule of law, because the higher the level of development of the state, the greater the number of disputes is considered non-state institutions. For the first time revealed some of the problems associated with the lack of a unified approach to the interpretation of the content of the alternative forms of protection of the violated rights, the relation of an alternative and extra-judicial dispute resolution. It proposed a responsible attitude to the use of terms related to the content of the alternative forms of protection of violated rights. Necessary legal education as a condition of formation of legal culture of the population. The structure of alternative ways of considering and resolving legal conflicts with the purpose of formation of legal culture of the population of the Orenburg region. We see the possibility of declaring the Orenburg region experimental platform development system of alternative means of resolving legal conflicts.Key words: legal culture, alternative, legal disputes, the concept of protection of the rights, protection of rights.

PSYCHOPHYSIOLOGICAL AND METABOLIC ASPECTSOF ADAPTATIONAND DISADAPTATIONOF STUDENTSStress factors are the causes of emotional stress, reduced functional reserves of the organism, stress leads to increased morbidity and mortality. That's why studying of the mechanisms of adaptation and disadaptation of person has special importance. The article presents the results of long-term studies of the psycho-physiological and metabolic parameters'changes during the adaptation to various environmental conditions. The peculiarities of physical development, lifestyle, eating habits, bad habits, as well as cardio and metabolic parameters in students of different ethnic groups were investigated. Elemental portrait of young men with information about the features of the element status shows that most abnormalities are not related with ethnicity, but are related with the region of residence. At the same time, it was shown the influence of the person individual characteristics on the process of adaptation of students. Correlation analysis between psychological indices and the parameters of adaptation showed that the largest number of correlations between psychological characteristics and cardioindicators were in the group of Tatars. In addition, it is was shown that the functional hemispheric asymmetry of the brain affected on the body's ability to adaptation. Right hemisphere dominant young men hada higher rate of reaction according to the tests "assess attention", "noise immunity", "simple hand-eye reaction". Regardless of the type of functional hemispheric asymmetry, the young men had deficient of cobalt, selenium, an excess of lithium, iron and zinc, compared with the optimal interval centile. Thus, the adaptability of the organism depends on many factors, and defining factors are ethnic characteristics, the type of functional hemispheric asymmetry, lifestyle and environmental living conditions.Key words: adaptation, disadaptation, students, element status, hemispheric asymmetry, ethnic groups.

THE FORMATION OF ENDOMETALLOFULLERENES LANTHANIDES CLUSTERS IN SOLVENT AND ON THE SOLID SURFACEThe formation of the clusters in solution and on a solid surface can significantly modify the photophysical properties of the studied systems. Process of endometallofullerenes (EMFs) lanthanides (La, Gd, Ce) clusters formation in the polar solvent (dimethylformamide š— DMF) and on the mica surface by static and dynamic light scattering methods as well as atomic force microscopy was investigated. It is shown that endometallofullerenes in the solvent and on the mica surface form a stable system of nanoclusters with predominant dimension 50–60šnm. The combination of the methods of dynamic and static light scattering allowed us to estimate the molar mass of the scattering centers. Based on these data, the conclusion about the fractal nature of the EMF clusters and the estimation of their fractal dimension dš—š2.3 has been done. Zeta-potential of the EMF clusters in the DMF solution was measured. It is shown that the EMFs clusters have a negative charge and its zeta-potential value is –30šmV.Key words: endometallofullerenes, nanoclusters, dynamic and static light scattering, atomic force microscopy.
Bakhareva N.F., Polezhaev P.N., Ushakov U.A., Shukhman A.E. MANAGEMENT OF ENTERPRISE SOFTWARE DEFINED NETWORKSThe existing solutions for enterprise networks have a number of drawbacks. First, there is a problem deciding where to install the security tools, which are usually placed at the subnet borders. This leads to the fact, that they only handle the traffic transmitted through them. It reduces the level of network security. Second, there is the problem of the efficient network traffic routing while ensuring quality of service at the appropriate level. To solve these problems we propose the usage of the software-defined network technology. On the base of this technology, the prototype's architecture for network security system of enterprise SDN is proposed. It includes the implementation of the algorithms for firewall, authentication, routing and delivering QoS. The proposed authentication algorithm for enterprise SDN supports IEEE802.1x, EAP, RADIUS, LDAP, WPA2-EAP. SDN is used to isolate the data streams of different users with the ability to create any number of isolated virtual networks without restrictions of VLAN, and to implement additional access control by firewall. The experimental results of the prototype research show the efficiency and suitability of the developed algorithms for enterprise SDNs. The results can be used to deploy enterprise SDNs in companies of the Orenburg region.Key words: software-defined networks, enterprise networks, authentication, routing, QoS, firewall.

ON THE HISTORY OF A FOREST MELIORATION FRAMEWORK DEVELOPMENT IN ORENBURG STATEOne of the primary problem ofsteppe use optimization and stable agro-landscapes development is formation and support of a forest melioration framework in the steppe region. Today, by virtue of a line of social-economical and agro-ecological problems systems of forest cultures developed before loses their agro-ecological functions, their breakup and collapse happen due to agro-lands demands reduction and fires acceleration. In this connection a development of a new concept of a forest melioration framework suitable for current condition and modern steppe science achievement is extremely topical and urgent. To develop a modern concept of a forest melioration framework is necessary to research spreading and dynamics of forest plantations as well as historical experience of steppe forest melioration. Using historical methods is revealed that before forest vegetation was represented more wide lyandvarious on the territory of modern Orenburgskaya oblast, especially on Common Syrt and in the Pre-Ural region, e.šg.šSiberian larch from the north reaches to in latitudeš53œ. Periodization of forest melioration with separation of three stages was developed in Orenburgskaya oblast. Herewith, the first stage fell on the middle of 1930s, but the main activity to develop a forest melioration was made during 1948–1953 in the frame of a rapid implementation of A Council of Ministers Resolution USSR and the Central Committee of C.P.S.U. (b) of 20.10.1948 №š3960. A scale of forest cultural activity and main objects, including a state forest belt "Vishnevaya mountain š— the Caspian sea" is shown.

Gur'eva V.A., Belova T.K. PROPERTIES OF THE CEMENT MORTARS FIBRE REINFORCED BY THE MODIFIED MICROFIBRE The cement mortars fibre reinforced by fibers fibers are one of perspective constructional materials in construction. Modifying of fibers carbon nanomaterials strengthens structure of a cement stone at various levels therefore the received composite possesses the increased operational properties. However, the fibers today modified weren't widely adopted in view of insufficient study of properties of cement composite materials on their basis. Results of research of properties of the cement mortars fibre reinforced by the basalt microfiber modified (MBM) the carbon nanomodifier are increase of durability of solutions on a bend, decrease in an istirayemost and relative deformation of shrinkage. Introduction of 1š% of MBM of the mass of the knitting leads to increase of durability on a bend to 60š% and to slight increase of durability on compression š— 4š%. Abradability of the cement mortars fibre reinforced by the modified basalt microfiber in comparison with the samples of similar structure dispersno reinforced by usual thin basalt fiber 50,2š% lower. With other things being equal introduction of the modified microfiber promotes decrease in size of relative deformation of shrinkage by 51š%, thus most intensively shrinkage develops in the first 7-10 days of curing. By results of tests it is possible to draw a conclusion that fibre reinforcing of cement mortars the microfiber modified by the carbon nanomodifier promotes improvement of structure of a cement and sand composite. As a result such operational characteristics of cement mortar as improve: durability on a bend, durability on compression, an istirayemost, shrinkage as a result of curing. Key words: fibre reinforcing, cement mortars, the modified microfiber, the carbon nanomodifier, solution durability, an istirayemost, shrinkage deformation.

COMPREHENSIVE ASSESSMENT AND RISK MIGRATION ABILITY OF HEAVY METAL CONTAMINATION OF SOIL AND VEGETATION COMPONENT SYSTEMSIn this paper, when considering the transport processes and substances such as heavy metals in the components of soil-plant systems assumed that this process is probabilistic in nature. The second assumption we adopted the current status of the independence of the system components from its previous state. This allowed us to consider the soil-plant system as a Markov chain with a finite number of states. The probabilities of a state determines the intensity of transitions substances system components. On the basis of the constructed mathematical models to calculate the risk of contamination of the soil, aboveground and root systems of plants with heavy metals. The risk of contamination of components of soil-plant system shows the likelihood that heavy metals accumulate in the soil, the root system and aboveground plant parts. The intensity of transition shows the magnitude and direction of transport of substances (heavy metal) the components of the system. Integral indicators characterize the overall distribution of heavy metals in the soil-plant-specific system. The differential indicator shows the distribution of one or the other metal in the soil-plant system.Key words: soil-plant system modeling, the risk of contamination by heavy metals, integral differential indicator.

Kislov D.A. IMPROVING THE EFFICIENCY OF LIGHT CONVERSION INTO ELECTRICAL ENERGY IN SOLAR DYE-SENSITIZED SOLAR CELL BY INTRODUCING INTO THE DESIGN OF PLASMONIC NANOPARTICLESWork on improving the performance of solar cells is constantly are carried out. One of perspective methods to enhance the performance is to use clusters of nanoparticles with plasmonic properties in the solar cell design. In our work we investigated the effect of metal nanoparticles with a plasmon resonance on the mechanisms of electrochemical photovoltaic cells based on nanostructured titanium dioxide. The basic idea is that if the dye molecule in the dye-sensitized solar cell falls to local amplification of the metal nanoparticles electric field, then it varies greatly absorption cross section. This effect leads to the fact that the photovoltaic cells generate more free charge carriers.In our opinion, this phenomenon is one of the most important in the description of the influence of metal nanoparticles with plasmon properties on the Gratzel solar cell.Shown, that the silver nanoparticles in sample design allow generate more photocurrent. Moreover, photo current rises up, with increasing of concentration nanosilver in the cell. It is found that the sample with the highest concentration of nanoparticles short circuit current value twice the value of the current in the standard sample. The analysis shows, that maximum plasmonic nanoparticles concentration in the solar cell, increases efficiency more than 2štimes in comparison with the standard sample. Furthermore, to investigate the capacitive and transport properties of the photovoltaic cell samples, was conducted a series of kinetic experiments. Shown, that presence in the structure of the cells of silver nanoparticles increases the capacity on 30š%. Furthermore, we show that the addition of silver nanoparticles in the cell considerably increases the diffusion coefficient. Since the sample with the highest concentration of nanoparticles the average diffusion coefficient is 20š% larger than the average diffusion coefficient in the standard sample.Key words: dye-sensitized solar cell, photovoltaic, surface plasmons, DSSC, metal nanoparticles, titanium dioxide, dye molecules, nanocluster, Gratzel solar cell.

Radial distribution of the average atomic concentration of polypeptides on the surface of gold nanoparticles are calculated on a 5-produced model calculations, estimated a mean square deviation. Approximation of the radial distribution of the average atomic concentration of the polypeptides was produced by the formulas obtained by the methods of the statistical theory for the distribution of the density of links of macrochain on the surface of spherical nanoparticle. Numerical values of the parameters of the approximation curves of the average radial distribution of atoms of polypeptides on the surface of spherical gold nanoparticles are presented in the table.

Kucherenko M.G., Nalbandyan V.M. POLARIZABILITY SPECTRA OF NANOCLUSTERS OF TWO COMPOSITE PARTICLES IN AN EXTERNAL MAGNETIC FIELDOn the basis of exact solutions of the Laplace equations in anisotropic conjugated fields the expressions are obtained for the electric dipole tensor polarizabilities of two-layer spherical nanoparticles with different materials layers in an external magnetic field. Based on these expressions the frequency dependence of the polarizability of composites composition of the metal/dielectric and dielectric/metal are studied for different values of the induction magnetic field tion, the radii of the cores and shells of the globules. The values of the material parameters (plasma frequency of metals and dielectric constant of nondispersion dielectrics) typical of noble metal (Ag, Au), silicon dioxide (SiO2) and optical glass are used for calculations. It is established that the spectra of the polarizability of a cluster consisting of two spherical particles with metal cores have two plasmon resonance separated in frequency, while particles with dielectric cores and metallic shells š— four. The influence of external magnetic field on the spectra of electric polarizability nanoclay-the method of spherical composite particles of different composition and geometry is investigated. As in the previously studied case of a homogeneous conductive particles in a magnetic field the splitting of the spectral peaks into individual components, which led to the increase of the magnetic field diverge in the opposite directions of the frequency scale is observed for clusters. Optical properties of composite nanoclusters with magnetized plasma of metal components by various geometric parameters of the system are studied. It is found that the frequencies of plasmon resonances in the spectra of the polarizabilities of the clusters have a strong dependence on the thickness distribution of composite particles. The conclusion is made the enhanced possibility of a change in the spectral optical properties of cluster (control of the shift of the resonances and their intensity) by varying the geometric parameters of the composites and applying an external magnetic field.Key words: two-particle cluster polarizability, layered nanoparticles, magnetic field, plasmon resonance.

FLYORESCENT DOSIMETRY IN PHOTODYNAMIC THERAPYThe long-lived photoexcitations relaxation processes of fluorophores in biological tissues with molecular oxygen presence are investigated. This subject has a practical significance because of the active elaboration of photodynamic therapy and optical diagnostic. The futures of delayed fluorescence and phosphorescence in erythrosine stained healthy and cancer-diseased mammary gland tissues of BYRB-line mice were investigated in vitro. The dominant role of diffusive-mobile molecular oxygen in relaxation of triplet-excited long-life states of the dye molecules in cells is determined. A novel phenomenon of suppression of stained tissue delayed fluorescence under pulsed laser irradiation was revealed. The phenomenon was named as light quenching of delayed fluorescence (LQDF). The using of this phenomenon will greatly simplify the determination of the radiation "dose" in photodynamic therapy directly during the treatment session. Statistically certain distinction between delayed fluorescence characterization as well as LQDF extent in healthy and pathological tissues was established.Key words: dosimetry in photodynamic therapy, optical diagnostic of pathologies, fluorophores, delayed fluorescence.

ATOMIC FORCE MICROSCOPYUSING IN IDENTIFICATION OF SPECIFICALLY MARKED MOLECULES AND MICROORGANISM CELLSIdentification of biological molecules and microorganisms is an important problem of the microbiology which is traditionally solved by means of the marked antibodies. However in most cases the corresponding methods are based on detection of a significant amount of the interacting molecules and don't allow to find out their distribution on a surface. One of possible solutions consists in use of a modern method of atomic force microscopy. In current work the specific complexes formedbynanodimensionallabels, containing colloidal gold or amorphous carbon on a surface of bacterial cages of S.šaureus and on a surface of plastic microwell immunological plateswere found and studied by means of atomic force microscopy. Morphological characteristics and the map of distribution of the revealed complexes on the studied surfaces were established. In experiments with tags sensitivity of a method was defined and comparison with the enzyme-linked immunoassay was carried out. The received results indicate high sensitivity of the offered method and certain advantages of carbon labels in comparison with gold labels, because of their easy detection and unambiguity in identification on the received images. Identification of microorganisms in model two-component biological systems was carried out and approaches to marking of bacterial cages in complex biological mixes was developed for the directed their allocation and the subsequent studying. Thus, use of a atomic force microscope in combination with nanodimensional carbon and gold labels, allows to realize a new way of identification of single molecules and microorganisms in complex biological mixes.Key words: molecules identification, microorganisms detection, gold and carbon labels, atomic force microscopy.

INFLUENCE OF SILVER NANOPARTICLES ON THE OPTICAL ABSORPTION SPECTRA OF ORGANIC DYES MOLECULES IN POLYMER SOLUTIONS AND MEMBRANESObjects and systems structured at the nanometer scale are of great interest among researchers due to the presence of their specific physical properties. Due to considerable experimental difficulties and limitations of theoretical approaches, the focus now is on study of relatively simple nano-objects for which there are suitable experimental methods, known methods of synthesis and physical models for theoretical description of their properties. As an example of such a system is considered colloidal solutions of metal nanoparticles and nanoparticles in polymer film. Influence of metal nanoparticles on molecular environment due to the presence of plasmon oscillations of electron gas density. This changes the interaction efficiency between nearby molecules with external electromagnetic field and the rate of photoinduced processes in this area. The influence of various concentrations of silver nanoparticles on absorption spectra of organic dyes molecules in water solutions and thin polyvinyl alcohol films is investigated. It is found that with increasing concentration of metal nanoparticles optical density of polymer solutions and films in the 380–450šnm band increases monotonically, as in the 490–570šnm band increases at low nanoparticles concentrations and decreases at higher nanoparticles concentrations. Maximum enhancement of the dye absorption is observed when at concentration nanoparticles near 10-9 M. Based on the model of influence metal nanoparticles on interaction of organic dye molecules with linearly polarized monochromatic electromagnetic field spatial orientation and frequency dependence of transition probabilities in dye molecule within nanoparticles is calculated. It is shown a qualitative agreement between the theoretical frequency dependences with the experimental results of concentration effect of silver nanoparticles on the absorption intensity of dye molecules in different spectral ranges.Key words: silver nanoparticle, organic dye, absorption spectrum, induced transitions.

THE SPATIAL ANALYSIS OF FACTORS OF TRANSFORMATION OF THE RIVER DRAIN IN THE CROSS-BORDER BASIN OF THE RIVER URALThe worldwide growing problems of water consumption makes it necessary to address them in the context of geo-political, socio-economic and environmental security of the regions. A considerable relevance of the problem priobre-melt water in water-scarce conditions and in regions with developed industrial and agricultural production. Within the Russian Federation, this combination is a characteristic of transboundary Ural River. The paper analyzes the natural conditions and human factors forming the river flow in the basin of the Ural River in terms of the development of the concept of integrated water resources management. Data on the spatial heterogeneity of the formation conditions of runoff caused by a combination of complex and vzaimouslovlennym zonal-climatic conditions, varied topography and landscape structure. Studies have revealed trends in the water regime of the rivers, expressed in the redistribution of water content on hydrological seasons, manifested in the reduction of the spring and increase the share of low flow, especially in the winter. The information about the most significant types of anthropogenic transformation of surface runoff, summarizes the parameters of the largest reservoirs. It is pointed out that the majority of dangerous hydrological situations observed in the basin of the Urals, provoked by human activities without regard to seasonal and long-term dynamics of channel processes. As an example, consider geo-ecological consequences of the construction of bridges and road embankments. The article states that the question of assessing the impact of flow regulation on a multi-year and annual transformation of the hydrological regime of watercourses Ural River basin remains controversial, and the findings of various researchers š— is not identical. Studies suggest that the transformation of the hydro-logical mode is defined as a geographical contrasts between the different parts of the river basin. Ural and anthropogenic factors. The results indicate the need for drawing up long-term forecasts in the development of water-ecological situation, but with a detailed assessment of the socio-economic and landscape-hydrological effects.Key words: transformation of a river drain, cross-border pool, regulation of a drain.
Stroganova å.á., Anufriyenko V.F. FEATURES OF COPPER (II) IONS STABILIZATION IN A PHASE OF AN ANIONIT AH-31 AT SORPTION FROM THE GERMANIUM CONTAINED CHLORIDE SOLUTIONSAnionit AN-31 is the low-basic aminofunctional anionite that defines high affinity ofd-metals ions. At the same time, due to existence of alcoholic hidroxyl groups, AN-31 shows selectivity to germanat-ions that allows to apply a sorbent in technologies of passing germanium extraction from copper solutions. Concurrent sorption of germanium and copper ions leads to receiving sorbates of difficult structure that doesn't allow to carry out full division of metals during desorption stage. Thus, the possibility of germanium, copper-containing sorbent usage is actual for optimisation of production schemes. In particular, cupriferous sorbents can be applied as catalysts of low-temperature processes. Our work is devoted to study the influence of solution composition on the way of copper ions stabilization in sorbent to indicate the catalytically active forms. Sorption was carried out at static conditions for various metals concentration, Òî and ionic force of solution. The content of metals in solution was determined by the titrimetry and photometry methods. The phase of a sorbent was investigated by methods of the electronic spin resonance (EPR) and the electronic spectroscopy of diffusion reflection (ESDR). Increase of Òî was shown to lead manifestation a dipole-dipolar interactions in associates of the hidroxocomplexies of copper which are localized in cavities of the polymeric matrix. Introduction of background electrolyte to solution increases hidroxocomplexes association with the exchange-connected copper ions. Presence of germanat-ions promotes strengthening of dipole-dipolar interactions of copper ions that is connected probably with concurrent sorption of metals heteronuclear complexes. Stabilization of copper ions in the phase of AN-31 is due to covalent connection of hidroxocomplexes of copper with aminogroups, and also to formation of oxidic dimers (-Cu-O-)2,oxidic oligomers Cun(OH)m and the square-planed oxidic clusters. Presenceof oxidic clusters implicits catalytic properties of a cupriferous sorbent.Key words: copper ions, germanium ions, stabilization, sorbent phase, electron spin resonance (ESR) method, electronic spectroscopy of diffusion reflection (ESDO) method, polynuclear hidroxocomplexes, associates, axial distortion, oxidic clusters.
