The available body of geological and geophysical data indicates that the morphologic structures of the Central Arctic submarine elevations complex (CAE) form a single complex block of continental crust that broke away from the Barents-Kara continental margin in the late Paleocene. Seismostratigraphic interpretation of the multichannel seismic reflection data acquired within the CAE, based on seismostratigraphic benchmarks confirmed by drilling and continuous tracing of pre-Cenozoic unconformities from the offshore North Chukchi Trough to its deep-water extension (Vilkitsky Trough), makes it possible to draw the following conclusions: The sedimentary-basin depocenters of the Vilkitsky Trough and Chukchi basin include pre-Upper Jurassic sediments in addition to Cretaceous complexes. However, the former are not common in the rest area of the CAE. Synrift extension of the continental crust is the key factor that affected the tectonic evolution of morphologic structures of the Central Arctic basin. Multichannel seismic reflection data show the clearest signs of the synrift extension in the Lomonosov Ridge, Mendeleev Rise, Chukchi plateau, and their flanks sloping to the sedimentary basins of the Vilkitsky Trough and Chukchi basin. At the same time, the depocenters of these sedimentary basins formed by pre-Upper Jurassic deposits are characterized by an almost undisturbed bedding of all sedimentary complexes. Pre-Upper Jurassic deposits might be interpreted as a relic of the Ellesmerian structural stage preserved in the deep-water extension of the North Chukchi trough since the preoceanic evolution stage. Pre-Upper Jurassic complexes seem to be affected by deep rift activity only within the elevations of the Central Arctic area and near-flank zones of the depressions separating them. Pre-Upper Jurassic deposits in the sedimentary basin depocenters of the Vilkitsky Trough and Chukchi basin structurally linked to the shallow-water shelf were barely affected by the rifting processes. The tectonic evolution of the depocenters and their submergence relative to the flank zones might have been affected not only by crustal extension processes but also by compensation mechanisms.

Keywords: Volcanic rocks, U-Pb zircon age, geochemistry, Nd isotope data, Paleoproterozoic, Siberian craton
Geological, geochronological, and geochemical isotope studies are carried out for metamorphosed volcanic rocks and dolerites of the Maltsevka sequence of the Elash Group in the Biryusa block of the Siberian craton. It is found that mafic igneous rocks (dolerites and basaltic andesites) are close in composition to intraplate basalts. Flat or slightly fractionated REE patterns ((La/Yb) n = 1.3-2.3) and positive εNd( T ) values of +3.7 and +4.1 are observed. It is assumed that the depleted asthenospheric mantle and, possibly, plume mantle were the sources of these rocks, while the lithospheric mantle had no significant effect. Meta-andesites of the Maltsevka sequence belong to the tholeiitic series and have high La, Th, and U contents. Pronounced negative Nb and Ti anomalies are observed in the multielement patterns of these rocks, along with negative εNd( T ) values of -4.6. It is assumed that meta-andesites resulted from the late Archean crustal melting with the participation of the mantle material. Metarhyolites prevalent in the Maltsevka sequence are divided into two groups similar in REE composition to А-type and I-type granites. A-type metarhyolites show high contents of Zr, Y, Nb, Th, and REE (except for Eu) and positive εNd( T ) values of +2.2 and might have resulted from the melting of a source with geochemical isotope parameters close to those of mafic igneous rocks of the Maltsevka sequence. I-type metarhyolites have low contents of Y, Yb, Zr, and Nb but high contents of Th and show negative εNd( T ) values of -3.7. They might have resulted from the melting of lower crustal diorite-tonalite rocks with addition of juvenile mantle material to the magma generation area. U-Pb zircon dating of metarhyolites of the Maltsevka sequence corresponding to A- and I-type granites showed that they are close in age, 1872 ± 10 and 1874 ± 10 Ma, respectively, which agrees with the age estimated earlier for granitoids of the Sayan complex of the Biryusa block. The similar ages and structural positions, along with the localization within the same structure, made it possible to unite volcanic rocks of the Elash Group and granitoids of the Sayan complex of the Biryusa block into a Paleoproterozoic volcanoplutonic association. The rocks of the association form the Sayan-Biryusa volcanoplutonic belt stretching for about 300 km along the zone of junction of the Biryusa block of the Angara fold belt and the Archean Tunguska superterrane of the Siberian craton. The belt is part of the large Paleoproterozoic South Siberian postcollisional magmatic belt formed at the final formation stage of the Siberian craton, when it was possibly part of the Paleoproterozoic Columbia supercontinent.

The Inagli zoned ring massif is located in the Central Aldan ore district. The close localization of ultrabasic and alkaline potassic rocks, magmatism, and mineralization (platinum, gem Cr-diopside, and vermiculite) make this object unique from both geological and economic perspectives. Formation of alkaline rocks in the Inagli massif was related to the Mesozoic tectonomagmatic activation of the Aldan Shield and occurred in several stages. Intrusion of clinopyroxenites took place no later than 145.8 ± 3.2 Ma, whereas most of alkaline rocks of the ring framing formed at 133-128 Ma. The feldspar-Cr-diopside-mica veins in the dunite core are dated at 133.4 ± 1 Ma.

Keywords: Composite dikes, mingling, zircons, U-Pb isotopic age, magma sources, Western Sangilen
Composite dikes (mingling dikes) of Western Sangilen (southeastern Tuva) are believed to indicate a shift from tectonic contraction, related to the mountain fold system formation, to postcollisional extension that ended with the disintegration of the collisional orogen. However, the position of composite dikes in the general sequence of magmatic events was based only on their geologic location and has not been confirmed by U/Pb isotope-geochronological data. The proposed study is concerned with the geologic structure, composition, and isotopic age (485-490 Ma) of West Sangilen composite dikes. The isotopic age of the host granites from the Matut pluton is 509 Ma; thermal events of Riphean (679-934 Ma) and early Paleozoic (484 Ma) ages are reflected in zircons from gneiss-granites of the Erzin metamorphic complex. The obtained data are consistent with the earlier determined sequences of West Sangilen tectonometamorphic events. Basites from the examined composite dikes are strongly different in the contents of indicator elements (Rb, Nb, Ta, Zr, and Hf) and the Nb/Y, Zr/Y, Th/Ta, Zr/Nb, and Nb/Th ratios, which is indicative of different (probably, different-depth) mantle sources. The protolith of the salic component of the combined dikes might have been rocks similar in composition to the autochthonous/parautochthonous gneiss-granites of the Erzin metamorphic complex.

Keywords: Alluvial placers, gold, mother lodes, gold fineness, impurity elements, grades/types of gold
On the territory of the Egor’evsk district, 3500 results of probe microanalyses of surface gold particles taken from 17 placers, weathering crusts, and orebodies were processed and summarized. High-fineness and mercury-containing gold is predominantly found within mother lodes and placers, and medium- and low-fineness gold is distributed in subordinate and dramatically subordinate quantities, especially in the placers. A unique feature of the gold composition, rarely occurring in other districts, is the constant and commonly simultaneous presence of mercury and copper impurities. Analysis of Ag, Hg, and Cu content variations has enabled us to identify five main grades of gold. The mother lodes of the predominant gold grades are metasomatites with beresite and listwaenite compositions, which are developed primarily after lower Cambrian volcanoterrigenous-carbonate rocks and ore-bearing mafic dikes. Mercury-containing gold is characteristic of beresites, but copper-bearing gold is typical of listwaenites. The relationship between corresponding grades of surface and ore gold is confirmed by the presence of microinclusions in the gold grains. Nonconformity between the content of gold from mother loads, weathering crusts, and placers is explained by the losses of Hg and Ag impurities by endogenous gold under subsurface hypergene conditions. Identification of mineral-geochemical properties of surface gold is of exceptional practical importance in ore-grade gold mineralization prediction.
The financial independence of regional and local budgets is the most important condition for its effective functioning. In Russia the most of socially significant expenditures is concentrated at the sub-federal level. The purpose of the study is to analyze the main directions of the formation and directions of the use of sub-federal budgets in the Russian Federation. The executed complex of calculations on materials of consolidated budgets of the subjects of the Russian Federation has allowed to reveal features of formation of revenues and expenditures of sub-federal budgets. The results of the research can be used to study the possibilities of improving the budget policy in the direction of equalization and stimulation of subjects of the Federation to strengthen their own revenue base. In addition, the analysis made it possible to characterize the budget situation at the sub-federal level from the point of view of the sufficiency of the financial resources for exercising its own and transferred powers.

The article considers the issues of impact of differentiation of the development of regions on economic growth of the country. The hypothesis of ambiguity of this interaction is checked against actual data; on the one hand, the inequality of levels naturally stimulates the need for economic growth, on the other hand, the excessive differentiation of territories creates the situations of social tension, as well as forms the negative trends of capital and labor migration, followed by an adverse effect on the parameters of economic development. The paper attempts to define for a particular territory whether the differentiation is a negative or, on the contrary, a motivating factor. The hypothesis is checked on the basis of calculation of the differentiation level of social and economic development of municipal formations of the constituent entities via the appraisal of concentration of gross regional product production over the territory of the country.

On the basis of econometric modeling a conclusion about low efficiency of state policy to promote small business in Russia has been made. The elasticity of the level of entrepreneurial activity in terms of state support does not exceed 0.3. The ways to improve efficiency include the replacement of budget subsidies by the expansion of tax benefits and the volume of government purchases from small businesses. The combined effect of these measures covers various aspects of business activities, which will increase the return on fiscal measures to support small businesses.

The aim of the study is formation of the measures of fiscal expansion improvement on the basis of the analysis of their current problems and approaches of usage for the purposes of spatial development of the country. The article appraises the core role of tax regulation; fiscal expansion is the crucial part of it. The paper considers two most important ways of spatial development of the country (creation of effective regional and interregional areas of innovation-oriented priority development and softening of social inequality of the regions, human capital investment) and reveals the issues of their modern realization. The article presents the analysis of the measures of fiscal expansion aimed at provision of the two main ways of realization of spatial strategy of Russia. The article offers the system of fiscal expansion, with both vertical directivity, aimed at the growth of entrepreneurial, innovative, technological and other activities, and with horizontal directivity related to economic leveling of the territories. As the first type of fiscal expansion, the author suggests defining a sequential and transparent gradation of taxpayers with marking out and support with fiscal expansion (regional and local taxes) of the profitable entrepreneurs and companies, which invest in technological, social and other development of the territories. The second horizontal type of fiscal expansion is based on the system of social and economic zonation, with marking out of the ‘peripheral’ territories, which are to be developed, among other things, at the expense of exemptions and preferences of federal taxes.
This article presents a cluster analysis of the value of organizations in the agricultural sector of the Russian Federation, calculated by discounting cash flows income approach. The relevance of the study is due to the fact that the value indicator is insufficiently studied by the factors affecting it and, therefore, it is necessary to take a comprehensive approach and apply statistical analysis methods to the valuation of the enterprise. Clustering will determine the type of distribution characteristic of the value indicator, as well as confirm or disprove the hypothesis that the analysis of the company will be divided into three groups: with an inflated value; with a value close to the balance sheet and with an understated estimated value. The results obtained can be the basis for the factor analysis and the construction of the integral index of assessing the value of companies of agriculture of the Russian Federation.

The paper analyzes the results of social research of unoccupied population regarding the possibility of their transition to self-employment, as well as of the entrepreneurs who set up their own business when they were unemployed. The studies were conducted in Novosibirsk region in 2015. The goal of the article is studying the preferences of the respondents in terms of the types, conditions, assistance in their transition to self-employment and comparison of the results with objective reality of carrying out of small business, revelation of issues and development of counter measures. Empiric and general scientific methods were applied: survey (type - polling), analysis of documents, analysis and synthesis, generalization and comparison and other. The novelty of the research lies in obtaining new empiric data, as well as in a special approach to analysis of the results. The article analyses the motives of setting up own business, the activities which are favorable to small business in terms of unoccupied citizens and entrepreneurs, the preferred type of activity within self-employment in personal subsidiary economy, the assistance necessary for transition to entrepreneurial activity; social and demographic parameters of the entrepreneurs, who set up their own business, as well as changes in their financial situation and social-psychological state are explicitly considered. A conclusion was drawn that the development of small business and self-employment as a complex approach to solution of the employment issues deserves more attention and support since it helps to break the established employment stereotypes, forms other systems of values and motives of behavior and facilitates the general growth in population prosperity and reduction of social tension in the society.

Subsection: THEORETICAL SEARCH AND OFFERS
This study examines the factors behind the development of a car service station. In the conditions of qualitative transformations of the economy in the Republic of Tajikistan and the entire system of public relations, the problem of creating modern car service stations is of particular relevance. It is organically connected with the main tasks facing automobile transport enterprises and is a significant component of the efficiency of economic activity. Currently, car maintenance stations have to resolve contradictions caused by imperfect structural relationships. There is a high degree of equipment depreciation, a shortage of own sources of financing, unavailability of loans due to high fees for their provision, low purchasing power hinders the demand for the sale of services. In the current situation, car service stations are seeking internal capabilities, optimizing their use. The leading place is occupied by the problem of effective use of potential. The decision of this problem depends on the definition of controlled factors affecting the activities of the car maintenance station, the development of recommendations for their restructuring, improvement of the internal structure and control mechanism. The crucial factor here is the management of factors, which largely determines the strategy and ways for the development of a car service station.
National pension systems are subject to reform because of the impact of both socio-economic and demographic factors. The reforms are mainly aimed at reducing state obligations to pensioners by raising the retirement age, stimulating later retirement, and abolishing the indexation of pensions for working pensioners. The article presents an assessment of the results of the pension system reform in Russia at the present stage. The achieved level of pension provision in Russia is compared with similar indicators of foreign countries. The prospects of the expected directions of pension system reform are evaluated.
The present work was devoted to an experimental study of small angles of attack and cone nose bluntness on the efficiency of stabilization of high-frequency disturbances in hypersonic boundary layer with a passive porous coating. The experiments were carried out on a cone with an apex half-angle 7° and nose bluntness radii R = 0.03, 0.5 and 1 mm installed under angles of attack a = 0–1° at the freestream Mach number M¥ = 5.8. High-frequency pressure fluctuations on the sides of the cone with the solid and porous surfaces were measured. It is shown that at all angles of attack and cone bluntness, the passive porous coating permits an efficient suppression of disturbances in hypersonic boundary layer both on the windward and leeward sides of the cone.
The hot-wire anemometry technique is used to study the development of controlled disturbances in a straight wing boundary layer. Three-dimensional surface oscillations with large amplitude generate two types of disturbances: the localized longitudinal structures and wave packets. In downstream direction, the intensity of localized longitudinal structures decreases. The wave packets manifest themselves near the fronts of longitudinal localized structure in the flow region with adverse pressure gradient. In the separation flow area, an intensive growth of the wave packets amplitude is observed. The spatial development of the wave packets coincides with the development of three-dimensional Tollmien-Schlichting wave under similar conditions.

The Hamiltonian equations of the motion of a system of N ideal point vortices in a simply connected two-dimensional region have been obtained by the methods of the theory of functions of a complex variable. It is shown that the motion of two vortices in a circle is integrated exactly; the periods of this motion have been determined. The motion of two vortices in a region bounded by a lemniscate has been investigated by the method of secant planes in the phase space. The stochastic trajectories have been revealed here, which have continuous power spectra. The supposed reason for stochasticity is the walk of the phase point over a homoclinic structure.
The paper is devoted to the study of the permeability of hollow microspherical membranes to helium with a narrow fraction of MS-V-1L microspheres taken as an example. In the course of the study, a special experimental facility for obtaining the sorption curves of various gases at given pressures and temperatures was created. A procedure for carrying out experiments and processing experimental data with the aim of evaluating the coefficient of helium permeability for the investigated type of hollow membranes was approbated. For the selected narrow fraction of MS-V-1L microspheres with diameters in the range from 35 to 50 mm, the helium permeability coefficient of the particle-wall material in the temperature range from 20 to 110°C and the activation energy of the helium sorption process by the microspheres were determined.

The effect of flow swirl parameter and thermophysical properties of the droplet of water, ethanol, and acetone on the structure of turbulent flow and heat transfer in a gas-droplet flow was studied numerically. To describe the dynamics and heat and mass transfer of the two-phase flow, the Eulerian approach was used. The growth of the volume fraction of small particles on the tube axis is typical of a swirling flow because of their accumulation in the zone of reverse flows due to the turbophoresis force. It is shown that the addition of droplets leads to a significant increase in heat transfer (more than 2.5 times) at mass concentration of droplets ML1 = 0.1 in comparison with a single-phase swirling flow. Intensification of heat transfer with the use of ethanol droplets is higher than that for water droplets (approximately 10–20 %) and acetone (up to 65 %). When using the droplets of ethanol and acetone, the region of two-phase flow existence reduces, and the degree of suppression of carrier phase turbulence decreases. This is due to a more rapid evaporation of droplets of volatile liquids.

This paper deals with 3D flow of thermoviscous fluid in the low compressibility approximation within a cubic-shaped domain enclosed between two flat plates with different temperatures. For two other directions, the problem statement assigns periodic boundary conditions, while the steady pressure drop is sustained for the head flow direction. Such formulation allows to trace the evolution of initial disturbances imposed on the main flow depending on perturbation properties. In this case, we consider a degenerate one-dimensional divergence-free noise that is modified by a special correlation filter. When the divergent noise is generated, the solenoid nature of random velocity field must be restored. The simulation demonstrates that random disturbance field development leads to two different scenarios: for the first low-amplitude case, the velocity profile loses initial inflection point and its flowrate increases by 1.5-1.6 times, but for the second one, the flow turbulization occurs destroying the flow core and decreasing the flowrate. In both outcomes, the transition to a steady flow mode in terms of either stationary velocity fields or statistical averages takes place for a long interval: up to dimensionless time units. The analysis of
simulated flow is based on integral kinetic energy curves and enstrophy and
also via spatial averaging of the obtained data arrays.

The joint steady-state motion of a rivulet of incompressible liquid and a gas flow in a microchannel was studied taking into account the action of gravity forces, tangential stress at the gas-liquid interface, and Van der Waals forces. The values of contact angle are calculated for various values of liquid and gas flow rates. It is shown that for a constant liquid flow rate, an increase in gas velocity leads to a decrease in the height of rivulet, and the surface of rivulet becomes flatter. A significant deforming effect of rivulet on the velocity distribution in gas is found.

The results of an experimental and theoretical investigation of highly subcooled ethanol in an annular flow-passage duct under the conditions of pulsed heat generation in the wall cooled by liquid flow are presented. The formation of a vapor film on the heater wall and long-lasting pressure oscillations of high amplitude in the duct (the self-oscillatory regime) have been observed in experiments. A mathematical model of the ethanol boiling up has been developed to take into account the evaporation of the overheated liquid near the heater wall and the vapor condensation in the flow of a subcooled liquid. The proposed model describes both the decaying oscillations of the vapor layer and the development of the self-oscillatory regime, which predicts well the amplitude and frequency of nonlinear oscillations. Numerical computations have shown that the self-oscillatory regime is realized due to evaporation of a periodically renewed microlayer on the heater wall. Computational results agree well with experimental data.

Based on the system of nonlinear equations of thermal conductivity for stationary temperatures of the gas layer, substrate, the first and the second layers of samples with a volumetric optical absorption coefficient, the features of the formation of a stationary temperature field in the photoacoustic cell have been investigated. Analytical expressions for the temperature field of the gas layer, two layers of the sample and the substrate, as well as a system of interrelated nonlinear algebraic equations for the steady-state temperature of the irradiated and rear surfaces of the first layer and the boundary between the second layer and the substrate have been obtained. The numerical solution of the system of nonlinear algebraic equations shows that with the increase of the absorption coefficient of the corresponding layer and the gradual transition from the condition (is the layer thickness) to the condition, heating increases significantly, and the dependences of the characteristic temperatures on the intensity of the incident beam become nonlinear. It is shown
that the sign of the thermal coefficient of the temperature dependence of emissivity
significantly affects the dependences of the temperature increment of the
surfaces of all layers on the intensity of the incident beam.
The problem of measurement of the in-flight velocity and temperature of particles in the light field of a pulsed-periodic laser was solved using contactless detection methods. The solution of the problem is based on using a spectrometer and a complex of laser and optical means. The diagnostic technique combines two independent methods for measuring the in-flight particle velocity: a passive one, based on the registration of the natural radiation emitted by the heated particles in the gas flow, and an active one, using the effect due to laser-beam scattering. Histograms of the statistical distributions of particle velocities for two operating modes of a coaxial nozzle were presented. There is no laser radiation in the first mode. There is pulsed laser radiation in the second mode. In the experiments, various powders (Al2O3, Mo, Ni, Al) with particle size distributions typical of laser deposition technology and various working gases (air, nitrogen, argon) were used. СО2-laser works in
pulse-periodic mode with a mean power up to 2 kW. Pulsed power reaches
several ten/hundred kilowatts. It is shown that in the field of laser
radiation, powder particles acquire additional acceleration due to the
evaporation and the appearance of a reactive force due to the recoil pressure
of the vapors emitted from the irradiated part of the particle surface. It
is shown that laser radiation can significantly affect the velocity and
temperature of powder particles being transported by a gas jet. At the maximum
carrier-gas velocity of up to 30 m/s, the velocities of single particles
due to the laser-induced acceleration can reach the values of the order of
120 m/s.
The
paper presents experiments on using alkali-surfactant-polymer compositions (for ASP flooding) in tests on cores saturated with highly viscous
oil. The phase behavior was evaluated for solutions with different
concentrations of alkali (NaOH) and surfactant (SDS) after mixing with highly viscous oil samples; this defined
the optimal agent compositions for producing Winsor type III emulsions. Experiments on core saturated with highly
viscous oil demonstrated the pumping of ASP agent in the form of aquatic
solutions surfactant/alkali and polymer after regular water flooding
give the gain in the oil displacement in the range from 19 to 37 %.

The paper presents a
mathematical model and calculation results for the process of gasification of
solid hydrocarbons (SHC) placed in form of spherical bedding inside channels
with variable cross section and washed with high-temperature gas. Parametric
study was performed for analysis of generator performance (mass flow rate and
gasification products) as function of different parameters: temperature and
composition of gas phase, thermophysical properties of SHC, sphere diameter in
the bedding, and channels configuration. The method for estimating the SHC
gasification process in a flow duct of low temperature gas generator (LTGG)
without loss of spheres shape (due to melting) was developed. The method offers
recommendations for obtaining the required level of mass flow rate and gas
temperature at the generator exit. These data can be used for analysis of
experimental results on SHC sublimation at the stage of preliminary
designing of the LTGG.
