Pupkov K.A., Shahin B., Korotaeva S.V.
Abstract
The article focuses on the technical issues of implementing such innovative forms of electoral technologies, such as electronic voting, in the Syrian Arab Republic. The article provides the definition of electronic voting in general, and of two of its main types: remote voting, carried out from uncontrolled environments with the help of public means of communication, such as mobile phones, personal computers, specialized electronic devices - terminals installed in places widely available, and stationary electronic ballot held in a controlled environment (at polling stations) using specialized hardware. Based on the analysis of advantages and disadvantages of each of these types of e-voting, as well as taking into account the information and telecommunication capabilities at the disposal of the Syrian Arab Republic made a choice in favor of a stationary electronic voting as meeting the basic requirements of the electoral process, implemented through the use of information technology - the efficiency, availability, reliability, security.As a model system, similar to that provided to adapt it to the existing system in the Syrian Arab Republic, the material and technical base and the necessary optimization, presents possibility to design and implement geographically distributed automated national system for the organization and conduct of elections at all levels, including through electronic voting, elected by the State Automated System (SAS) of the Russian Federation “Elections” as best suited to the task, information and telecommunication capacities of the Syrian Arab Republic. Selecting the SAS of the Russian Federation “Elections” as a reference model is also due to the experience of the successful conduct with the help of its member systems of automation, in the particular systems for electronic voting, stationary electronic voting. The article provides a brief description of how the hierarchical structure of the SAS of the Russian Federation “Elections”, as well as the complex of technical devices for the electronic voting, distinguishing the efficiency and reliability of its use, suitability for e-voting organizations outside the country, that in today’s geopolitical environment is a priority for the Syrian Arab Republic.

THE GRADE OF GEOLOGICAL AND PETROLEUM AND GAS POTENTIAL INVESTIGATION OF RUSSIAN PLATFORM (RUSSIAN PART) IS THE BASE FOR THE NEW STRATEGY AND TECHNOLOGY ELABORATION FOR HYDROCARBON ACCUMULATIONS EXPLORATION
Seyful-Mulyukov R.B.
Abstract
The depth structure and rocks composition of Eastern part of the Russian platform have been investigated in the high grade. Within this territories hundreds petroleum and gas fields were in exploitation. For their exploration the different types of geophysical and geological methods were applied. These data allows consider and evaluate their effectiveness as well as theoretical base. The data shows that the postulates of organic petroleum and gas genesis paradigm dominating in the petroleum geology and teaching of the students in universities all over the world are not in line with real modern data and information. The history of petroleum exploration works within that territories demonstrate full independency of dominated model of petroleum genesis from methodology and strategy of petroleum exploration. It substantiated that the search for the petroleum accumulations depends on the withdrawal of two uncertainties. First is static one and it composed by the trap, reservoir, shield and canal of petroleum migration. Their location is the uncertainty. Currently it declining by 3D seismic survey methods. Second is dynamic uncertainty dealing with discrete process of petroleum hydrocarbon molecules formation. This process could not be expressed by exact mathematical means, but could be determined approximately applying the mathematical theory of fuzzy sets with very high grade of the approach to the petroleum accumulation existence.

TECTONIC PALEORECONSTRUCTION OF KOLGAN THICKNESS ON THE BASIS OF TIME SEISMIC CROSS SECTION WITHIN THE DONETSKO-SYRTOVSKY FIELD
Denisov S.B., Usova V.M.
Abstract
Results of the analysis of a paleotectonic structure of the Donetsko-Syrtovsky field are given in article. Ideas of tectonics of the Donetsko-Syrtovsky field were created as a result of generalization of materials of structural, search, prospecting drilling and a complex from seismoprospecting works. As a result are allocated western - Donetsk and east - Syrtovskoye the raisings divided by a superficial deflection. Results of seismoprospecting works 3D have allowed to gain the most detailed impression about a geological structure of the field. As a result of the executed reconstruction of time seismic cross sections and cubes of data no amplitude diagonal and orthogonal tectonic faults which influence on conditions of sedimentation wasn’t established are allocated. The main feature of morphology of all allocated surfaces supposes an inheritance of structural forms at their gradual planation up to surface. It is established that crest parts of local raisings almost flat, and wings abrupt what demonstrates close connection of tectonics of the base and a sedimentary cover. For the paleotectonic analysis, both data of GIS, and time seismic cross section the corresponding borders (reflecting, stratigrafichesky), being alignment surfaces have been chosen. The main sign of surfaces of alignment according to GIS are the lithological differences of breeds sustained on thickness and structure. In a terrigenous section, as a rule, borders of alignment are dated for a closing stage of formation of sedimentic cycles. The mail results of paleotectonic analysis of time seismic cross section: deposits of kolgan thickness were formed in the conditions of an active phase of the tectonic process dividing the Donetsk and Syrtovsky raisings; the active syndepositional phase of tectogenesis has exerted impact on nature of distribution of sandy material in deposits of kolgan thickness.

STRUCTURAL POSITION OF CHROMITE MINERALIZATION AT THE DEPOSIT CENTRAL (POLAR URALS)
Markov V.E., Karelina E.V., McGarrell D.S.
Abstract
The article presents the results of detailed structural studies carried out by us in the field of chromite ore Central, located in the massif of ultrabasic rocks of the Rai-iz in the polar Urals. The investigations included the mapping of structural elements in a rock: layering, pyroxene cleavage and the lineation of accessory chrome spinel, as well as the study of the morphology and spatial position of ore bodies that are installed from trenches and boreholes in the period of exploration and currently confirms in the mining process. The result of this work revealed the structure of host rocks and the relationship of the ore zone as a whole, and individual ore bodies with the elements of the structure. The layering creates an open sinform fold NE-SW trending, with subvertical axial surfaces and steeply (50°) sinking hinge toward North-Eaet. The enstatite flattening and related cleavage occupy the position corresponding to the axial surfaces cleavage of the folds, and the lineation of chrome spinel oriented parallel to its hinge. The ore bodies form a linearly elongated zone that can be traced along the axis of the folds to 1,5 km with a width of ~ 350 m. The prevailing ore bodies have flattened-lenticular and tubular form. Almost all ore bodies fitted steep (40-60°) North-Eastern declination. Thus, the structure of layering controls the spatial position of the ore zone as a whole, with individual ore bodies can be both intersecting and agree with banding. The flatness of enstatite defines the strike of the ore zone. The lineation of accessory chrome spinel reflects the decline of the ore bodies.

COMPOSITION AND ORIGIN OF POSTGLACIAL BOTTOM SEDIMENTS FROM CENTRAL AND NORTHEASTERN PARTS OF THE BARENTS SEA (RUSSIAN SECTOR)
Kostyleva V.V., Chamov N.P., Lyapunov S.M., Sokolov S.Y., Kotelnikov A.E.
Abstract
The lighology of postglacial bottom sediments are studied in cores from central and north-eastern part of the Barents Sea (25 and 28 cruises of R/V “Academic Nikolai Strakhov” in 2007 and 2011 respectively). Petrographic and chemical composition of modern and late Quaternary sediments from the Fedynskii swell area and the southern rim of the Franz Josef Land were examined. The study revealed sources of clastic material and permitted to estimate their influence on the various stages of post glacial sedimentation. At the end of Late Pleistocene (the initial phase of the ice cover degradation) granitoid rocks of the Kola peninsula are considered to be the main source of clastics in the Fedynskii swell area, while volcanic-sedimentary strata that compose FJL governed sedimentation in the North- East. Sedimentation was accompanied by intense ice-rafting that resulted in mixing of clastics from both sources. Ate the Late Pleistocene to Holocene boundary and later in Holocene the main source of clastic material remained unchanged in the central part of the sea. In the North-East sedimentation was controlled by recycling of previously accumulated deposits. Ice-rafting had no significant values such as at early deglaciation phase. In the case of poor faunal characterization and/or the absence of radiocarbon data petrographic and geochemical study can be used for stratification of the Barents sea bottom sediments.

GOLD-BEARING MINERALIZED ZONES OF THE YUZHNOE ORE OCCURRENCE AND ITS COMPARISON WITH LODE GOLD DEPOSITS OF YENISEI RIDGE
Mansurov R.K.
Abstract
The relevance of the discussed issue is caused by the need to detect a new gold ore deposits within the Yenisei ridge to replenish the mineral resources of gold ore in Russia. The main aim of the study is to explore the features of geological structure and gold ore mineralized zones of ore occurrence Yuzhnoe in order to forecast gold ore bodies, and to substantiate the continuation of geological exploration. The prospecting is realized by the express method of prospecting of gold ore deposits in difficult mountain-taiga landscapes using a complex of lithogeochemical sampling for secondary dispersion halos, schlich, point and trench sampling; spectrochemical analysis for determination of gold content, ICP-MS, atomic-and-absorption, X-ray phase analysis and isotope-geochemical methods are used. The complex of prospecting methods allowed to reveal the ore-controlling zone of fold-discontinuous deformations and localize within it the ore occurrence Yuzhnoe. This ore occurrence is located at the south-eastern part of the Sredne-Ishimbinskaya area in the zone of dynamic influence of Ishimbinskiy deep fault system. The gold ore mineralized zones are revealed within the ore occurrence. They are presented by a series of lode gold stockwork subparallel bedding zones with low average gold content. A detection of gold ore bodies is forecasted within the most wide and lengthy zone Central`naya. Continuation of geological exploration is recommended. A comparison of the ore occurrence with model objects is carried out. A set of common criteria and indicators of ore occurrence with lode gold-sulfide deposits of the Yenisei ridge - Olimpiadninskoye, Veduginskoye, etc. and with «carlin» type deposits is established. For the first time in the region the gold ore mineralized zones in carbonate-terrigenous carbonaceous sediments of kartochki and aladyinskaya series of the Middle Riphean are detected. Perspectives of gold-bearing mineralization of the eastern slope of the Yenisei ridge are defined.

A STUDY OF THE RESOURSE OF BEARING CAPACITY OF THE LARGE-SPAN ROOF OF A STADIUM MADE OF ORTHOGONAL METAL TRUSSES
Lebed E.V., Mitev J.M.
Abstract
Based on an overview of the roof systems of football stadiums, a structural system of a large-span roof made of orthogonal 2-D metal trusses was developed. A computer analysis of bearing capacity of the roof was performed under the assumption of the abnormal increase of the snow load.It has been demonstrated that a limited number of additionally installed metal bars can significantly increase the bearing capacity of the roof. The role of these bars is to reduce the effective length of the most loaded elements of the grid of metal trusses for in-plane and out-of-plane buckling.The limit values of snow load for consecutive steps of reinforcement are established, and the effect of the added bars on the bearing capacity of the roof structure is estimated.The results of the investigation are presented in the form of drawings and diagrams. Conclusions are made on the resource of the load-bearing capacity of the large-span roof of the stadium made of 2-D orthogonal trusses.
