Semi-Empirical Method for Determination of Air Relative Humidity on Results of Sun-Photometric Measurements of Precipitated Water Vapors

Authors: Asadov H., Abdullayeva S., Aliyeva A.

The paper is devoted to suggested semi-empirical method for determination of air relative humidity based on results of measurements of precipitated water vapors using sun photometers. The analysis of known Butler method make it possible to predict the presence of extremes in functional dependence of precipitated water vapors on relative humidity on the earth surface.

Foreign Students in Russia: Educational Migrants or Potential Residents

Authors: Ustavshchikova S. V.

The article discusses the trends of educational migration to Russia, including the geography of migrants’ origin. The main stream of educational migrants comes from neighboring countries. To smooth out the country’s demographic problems, educational migrants are the best migrants. These are highly qualified young people who have undergone adaptation and integration during their studies. The country needs to break the stereotype of migrants from Central Asia only as low-skilled workers.

Structural Differences in the Industry of the Volga Region

Authors: Preobrazhenskiy Y. V.

The article raises the question of complementarity of economic structures of a number of the Volga and Ural regions within the supraregional formation, which can be the Volga economic region or the Volga-Ural macro-region. The degree of changes in the structure of the manufacturing industry of the Volga regions over the decade is estimated, including taking into account the dynamics of the production of innovative products.

Foreign Research Experience of the Non-Street Passenger Transport

Authors: Ataev P. G.

The development of urban agglomerations is connected with the solution of the issues of territorial zones allocation and ensuring their transport accessibility. The purpose of the article is to determine the theoretical and methodological foundations of this subject. A review of foreign studies on the topic of extra-street passenger transport is conducted. The terminology used in foreign literature is defined. On the example of urban metropolitan areas of the USA, the development of public transport and the position of researchers on this issue are considered.

Angarsk City District – Modern Economic-Geographic Development

Authors: Aleksandrov E. Y.

The article is devoted to the modern economic and geographical development of one of the main industrial and agricultural subregions of the Irkutsk region, which transformed in the time dynamics from a large Soviet, post-Soviet industrial city of regional subordination into the modern Angarsk urban district (hereinafter AGO). The AGO structure is a «modular designer» from the city of Angarsk and the non-urban areas (the settlement of Meget, village Savateevka and Odinsk and 11 small settlements).

The Conditions of Development and the Activity of Exogenous Geological Processes on the South-Western Coasts of Crimea from Cape Aya to Cape Sarych

Authors: Agarkova-Lyakh I. V., Lyakh A. M.

The history of the study of the southwestern part of the Crimean coast between cape Aya and сape Sarych was considered. The conditions determining the development of exogenous geological processes on the coasts studied were characterized. They are: the type of coast, the tectonic construction and the direction of tectonic movements, maritime relief, lithological composition of the coasts. Genesis, morphometric characteristics, granulometric and material composition of the beaches forming here are described.

Studying Linear Erosion by Means of Creating a Refined Digital Elevation Model Based on SRTM (The Khvalynsk District of the Saratov Region as an Example)

Authors: Fedorov A. V., Shlapak P. A., Muzhenskiy D. A.

This article considers the methodology for constructing a digital elevation model and its derivatives for analyzing the spatial distribution of linear erosion processes using the territory of the Khvalynsky district as an example. The authors propose the creation of a refined terrain model based on SRTM radar data, topographic maps and the interpretation of Earth remote sensing data. The creation technology is described and a comparative analysis of the refined model with the base SRTM is carried out.

On the Question of Assessing the Quality of Green Plants for a Comfortable City Environment (on the Example of the Pedestrian Zone «Rakhov Street», Saratov)

Authors: Romanova A. Y., Tsoberg O. A.

The article discusses the creation of a comfortable urban environment in the central part of the city of Saratov. The data on reducing the area of green spaces, the results of the assessment of air pollution from vehicles against the backdrop of an unfavorable terrain are presented. It is established that the indicators of complex environmental pollution of the pedestrian zone of Rakhov Street have a tendency to increase after its reconstruction.

Correlation Relationship between the Protein Content of Spring Wheat and the Average Monthly Air Temperature in June at the Station «Saratov South-East»

Authors: Pryakhina S. I., Ormeli E. I.

The article presents a forecast of grain quality of spring wheat, obtained on the basis of the correlation of grain protein content with the average monthly air temperature in June. The correlation coefficient of the found dependence was 0.75, the equation justification was 94%. The statistical significance of the model is confirmed using Student’s criterion, the analysis of residual deviations and using the Kolmogorov-Smirnov criterion.

Macroregions as Supra-Regional Innovation Systems: The Problem of Knowledge Spillover

Authors: Preobrazhenskiy Y. V.

The necessity of formation and development of supra-regional innovation systems within the country for the effective flow of the innovation cycle, dissemination of knowledge and innovations is substantiated. The properties of the regional innovation system including those relevant in the Russian conditions of low population density and economic activity are discussed. The hypothesis that the macro-regions of Russia are considered as a super-regional innovation systems is tested. The regions – scientific and innovative centers-are singled out.
