MATHEMATICAL MODEL OF PORTLAND CEMENT KINETICCURING REGIMES IN SULFUR-LIMY SOLUTION

The article covers the chemical method of concrete mixes modifying by setting themin sulfur-limy solution. Mathematical models of concrete curing dynamics are found, depending on concentration of sulfur in the solution, namely:- steady curing rate is observedinthe solution with low content of chemical additives (concentration of Scommon = 0,5-2,5 g/l); - obviously unsteady curing rate is observed in the solution with sulfur concentration at the range of3 to 180 g/l;- steadily high curing rate is observed in the solution ofcorresponding saturation (up to 220 g/l).

Social policy of the state in interrelation with the general economic policy instruments

Social policy in the Russian economy is currently being superimposed on the common actions of the state in the regulation of economic processes and the implementation of the overall economic policy of the state. The situation in the Russian economy in turn develops within the framework of the formation and presence of certain objective constraints affecting the effectiveness of social policy implementation. Insufficient financial resources, the crisis situation and the availability of different points of view regarding the future path of development and the effectiveness of the necessary tools used by the state significantly influence the development of a number of negative social consequences, determine both the potential opportunities for implementing social policy and the actual conditions for the implementation of the process of interaction between social and economic politicians. The conditions for the implementation of social policy require taking into account a number of points in the applied tools of economic policy: possible delay in the actions of the state in comparison with current economic processes, taking into account the formed mentality of the population, Pareto efficiency in determining the optimal balance between state actions to stabilize the economic situation and household activities within the framework prevention of a decline in the level of well-being. Indirect factors determining the basic conditions for increasing the effectiveness of social policy of the state form potential opportunities for economic development

Economic development and migration

© 2015, Mediterranean Center of Social and Educational Research. All rights reserved. At present population migration is a global problem that requires a serious and deep analysis of both how to address underlying causes of migration and its socio-economic consequences. Analyzing migration flows is necessary for both the source country and the recipient one. Migration issues in contemporary society are interrelated with the problems of economic development, with the problems of human rights and determine the features of the society development

Russian oil and gas regions during the COVID-19 crisis and their digital transformation

Relevance. One of the key long-term strategic goals of Russia's economic development is to increase the share of the digital and green economy in the gross product of the country and its regions.  The recession caused by the pandemic has brought to the forefront the challenges of digitalization in the country's oil and gas sector, which was among the hardest hit sectors, and thus required significant effort on the part of regional governments.Research objective. This research aims to demonstrate the key role played by digitalization and environmentalization in the recovery of the Russian oil and gas regions from the pandemic.Data and methods. The study provides an overview of the Russian and international research literature on the ways to foster economic recovery and growth after the COVID-19 pandemic, including the publications of the United Nations and the World Economic Forum. Methodologically, the study relies on the empirical, general scientific methods and methods of economic statistics. We used in our calculations the data from the open-access statistical yearbook 'Russian Regions' published by Rosstat.Results The study analyzed the challenges of digitalization faced by Russian oil and gas regions to show the need for institutional transformations on the national level. We also formulated some recommendations for the improvement of the evaluation of regional governments' digitalization efforts in the context of the COVID-19 pandemic and the more general evaluation of the digital transformation of regional economies.Conclusions To stimulate economic growth of Russian oil and gas regions recovering from the pandemic, a viable strategy would be to place a greater emphasis on their sustainable and digital development. In the international rankings such as the EDGI Ranking presented  annually by the United Nations Department of Economic and Social Affairs (UN DESA), Russia occupies a high position in terms of e-government services and digitalization in other spheres. Nevertheless, as far as the Russian oil and gas regions are concerned, there are considerable disparities in terms of digitalization. To accelerate digital transformation, we would highly recommend to improve the methods of evaluation of the digital progress in regional government, especially to include a set of indicators characterising regional governments' responses to the challenges posed by the COVID-19 pandemic

Inequality and economic growth in the Russian economy

© MCSER-Mediterranean Center of Social and Educational Research. During the transformation of the market economy in the last decade, its advantages, competition, price mechanism and efficiency in the allocation of society's resources could be combined with social policies. In a modern economy market mechanisms don’t warrant themselves in a number of spheres. For increase of efficiency of functioning of the economy in general these spheres, as well as addressing the global challenges of poverty reduction and inequality are subject to the government regulation. Problems of inequality and poverty in the Russian economy are directly concerned with the problems of achieving positive economic growth. Economic growth forms the environment that provides reduction of excessive inequality

Impact of regional economic development on migration processes

Factors influencing intensification of a migration process should be defined as the potential opportunities of migration, and the actual conditions of implementation of a migration process. Conditions of implementation of a migration process require to determine the intensity of the migration process for formation of priorities within the framework of migration, as well as the quantitative and qualitative dimensions of migration. The factors influencing a migration may be divided into direct (inequality level, poverty level, the value of individual's real income, and the value of his/her real wages), and indirect which include the effectiveness of a national or regional economy (when considering the migration processes within one country). Direct factors permit a comparison of the parameters in the countries interrelated with a migration process. Changes in these parameters that are adjusted to the expectations of migrants and to the existing information asymmetry upon formation of the optimal solution for the migration enable virtually (on the basis of the information collected) to evaluate the importance of each of these parameters during formation of a decision to migrate. Indirect factors which determine the basic conditions of an intensification of the migration process is form the potential opportunities of migration. It is necessary to include in the number of indirect factors not only parameters of a national economy as a whole, but also the parameters of the development of certain regions or areas which form a migration attractiveness of these regions. In this case the migration attractiveness should be defined both by the overall macroeconomic parameters of the region development, and by a socio-psychological climate, and social development priorities

Microbiome of abandoned soils of former agricultural cryogenic ecosystems of central part of Yamal region

Microbial activity plays a crucial role in the development and formation of soil properties. The active and abandoned agricultural soils in the Arctic zone represent a valuable resource that can play a crucial role in providing food security in the northern regions. The reuse of abandoned land for agriculture will reduce environmental risks in the context of a changing climate. Therefore, there is a need for monitoring studies to assess changes in soil parameters after long-term abandonment (taxonomic diversity, agrochemical and physico-chemical qualities). In the study, we evaluated the taxonomic diversity of the microbiome in abandoned (postagrogenic) and pristine soils of the Central part of the Yamal region. In the process of taxonomic analysis, more than 30 different bacterial and archaeal phyla were identified. The formation of a specific microbiome associated with anthropogenic influence in post-agrogenic sites has been shown. Most common types of soil microorganisms in samples collected from pristine and postagrogenic soils were Firmicutes (average 26.86%), Proteobacteria (average 23.41%), and Actinobacteria (average 15.45%). Firmicutes phylum was found mainly in the agrocenoses soils, Proteobacteria were mainly described in the mature tundra soils, Actinobacteria in humid conditions. An increase in diversity indices in postagrogenic soils was shown
