Family Size of Workers in Western Siberia in the First Quarter of the XX Century

Y.M. Goncharov, V.N. Faronov
Keywords: Siberia, workers, family, demography, family size, children
Pages: 19-22

Abstract >>
The paper describes changes in family size and number of children among the workers in Western Siberia in the first quarter of the XX century. At the beginning of the century there was a tendency of reduction in family size among the workers, replaced in the 1920s by a temporary tendency of growth. A tendency of reduction in the average number of children is also noted. This is explained by gradual decrease in economic need for having a large family so far as the workers became less dependent on agriculture. Other reasons were the increasing involvement of women in industry, low level of capitalism development in Siberia and, as a result, low demand for the cheap child labor.

Y.A Kuznetsova
Keywords: demographic process, family, marriage, Siberia, Republic of Buryatia, the age and sex structure, migration
Pages: 38-44

Abstract >>
The article describes the conditions, factors and trends in family and marriage relations in the 1970s- 1980 s in the Republic of Buryatia, one of the largest multinational regions of Eastern Siberia. Among the determining factors in the development of population of the Republic in this period was intense industrial and transport development of its remote northern areas and the construction of the BAM. This led to large-scale migration of young people and a qualitative change in the population by sex and age, which was reflected in the structure of the family relations. The article analyzes dynamics of demographic development of the country, and reveals general and specific features of development of the family relations in the region.

Keywords: high-speed, high-enthalpy flows; apparatus channels; cavity; turbulence; experiment; mathematical modeling
Pages: 673-687

Abstract >>
Results of an experimental and numerical study of supersonic turbulent high-enthalpy flow in a channel with cavity are reported. On the basis of wind-tunnel tests performed in the IT-302M short duration wind tunnel, data on the flow structure and on the distribution of static pressure along the model walls were obtained. These data were subsequently used to verify the numerical algorithm. In the calculations, a parametric study of the effects of Mach number, cavity configuration, and temperature factor on flow quantities was performed. It was numerically shown that variation of the above parameters leads to a transition of the flow regimes in the vicinity of the cavity.

Keywords: temperature, nonstationary heat transfer, turbulence, wall, ribs, flow, heat exchanger
Pages: 689-696

Abstract >>
Results of experimental investigation of nonstationary temperature field in the flow and on the surface of the channel with corrugated wall are presented at a jump-like change of heat release in time. The changes were performed at the air flow in a rectangular channel, whose one heated wall was made as a plate with triangular corrugation oriented at 45º relative to the main flow direction. The microthermocouples with the thickness of below 10 microns were used to perform these changes. Investigations revealed typical regularities of temperature evolution in the flow and along the perimeter of the heated rib. Experimental data on time-temperature dependence are approximated well by the exponential function.

Keywords: apex, magnetohydrodynamics, MHD, finite difference, Nusselt number, vertical cone, variable viscosity
Pages: 697-710

Abstract >>
Free convection flow over an isothermal vertical cone immersed in a fluid with variable viscosity and MHD is studied in this paper. Using appropriate variables, the basic equations are transformed into the non- dimensional boundary-layer equations. These equations are then solved numerically using a very efficient implicit finite-difference method known as Crankl—Nicolson scheme. Detailed results for the velocity, temperature, skin friction, and heat transfer rates for a selection of parameter sets consisting of the viscosity parameter, magnetic field parameter, and Prandtl number are discussed. In order to validate our numerical results, the present results are compared with the available work in the literature and are found to be in an excellent agreement.

Kutateladze Institute of Thermophysics SB RAS, Novosibirsk, Russia
maltzev@itp.nsc.ru
Keywords: falling liquid film, film disruption, dry spot, simulation
Pages: 711-718

Abstract >>
Mathematical simulation of isothermal film flow for a viscous ponderous capillary liquid with dry spots on a solid substrate was performed. The algorithm was developed for calculation of the shape of a ridge (around the dry spot): this algorithm takes into account gravity forces, surface tension, friction, and inertia effects. Simulation results performed by original method were compared with experiment and previous method that takes into account only gravity and capillary forces. It was demonstrated that both methods produce similar results at low Reynolds numbers. However, at Reynolds higher than one these two methods give different results.

Keywords: power engineering, internal electrolysis, atomic energy, thermonuclear reactor, combined cycles, electronic and ionic chains
Pages: 765-767

Abstract >>
The role of energy and methods of its saving for the development of human society and life are analyzed. The importance of future use of space energy flows and energy of water and air oceans is emphasized. The authors consider the idea of the unit for production of electric energy and pure substances using sodium chloride which reserves are limitless on the planet. Looking retrospectively at the development of power engineering from the elementary fire to modern electric power station, we see that the used method of heat production, namely by direct interaction of fuel and oxidizer, is the simplest. However, it may be possible to combust coal, i.e., carbon in salt melt, for instance, sodium chloride that would be more rational and efficient. If the stated problems are solved positively, we would master all energy properties of the substance; and this is the main problem of thermodynamics being one of the sciences on energy.

Abstract >>
Via the selective oxidative transformations of double bonds in (+)-(3S)-3,7-dimethylocta-1,6-diene (dihydromyrcene), the main thermolysis product of (+)-cis-pinane, efficient schemes are developed for the synthesis of a number of optically active insect pheromones.

Abstract >>
A predominant role of volcanic factor in strengthening the springtime ozone anomalies over Antarctica has been demonstrated. Correlation analysis was performed concerning the average data for September and October with respect to the areas of polar stratospheric clouds and the ozone hole over Antarctica as well as with respect to minimum temperature values in the stratosphere at an altitude of 18 km, during three 11-year period from 1979 to 2011. It is demonstrated that the accelerated growth of the ozone hole in the early 1980s coincided with the maximum gas emissions of the Antarctic volcano Mount Erebus. Within the subsequent 11-year period, increasing the area of the ozone hole was caused by an abrupt increase in the content of sulphuric acid aerosol in the stratosphere over Antarctica associated with powerful volcanic eruptions of Mount Pinatubo and Hudson Cerro in 1991.
