On modelling of different sectors of economy in terms of sustainable development

© Medwell Journals, 2016.Modern industrial production consumes much energy, capital and labour to maintain adequate competitive position. Such development puts the reliability of industrial production at risk as well as can deprive future generations of the opportunity to meet their own needs. The study is aimed primarily to develop a method of assessing production reliability in various sectors of economy based on a balanced scorecard system in accordance with the concept of sustainable development. The key method of studying this issue is modelling that looks into a matter of this issue as an object-oriented and orchestrated process of improving different sectors of economy

EARLY PRECAMBRIAN CRUSTAL EVOLUTION OF THE BELOMORIAN AND TRANS-NORTH CHINA OROGENS AND SUPERCONTINENTS RECONSTRUCTION

Comparative analysis of the crustal evolution of the Early Precambrian Belomorian and Trans-North China orogens (Fig. 1) has shown [Slabunov et al., 2015] that: Both belts were formed by the superposition of two Precambrian orogenies. The earth crust of the Belomorian belt was produced during the Mesoarchaean to Neoarchaean Belomorian collisional orogeny [Slabunov, 2008; Slabunov et al., 2006] and then was reworked during the Palaeoproterozoic Lapland-Kola collisional orogeny [Daly at al., 2006; Balagansky et al., 2014]. The earth crust of the Trans-North China orogen was formed during a Neoarchean accretionary orogeny and then was reworked during a Paleoproterozoic collisional orogeny [Zhao et al., 2012; Guo et al., 2012, 2005]. The Lapland granulite belt is the core of the Lapland-Kola Palaeoproterozoic collisional orogen in the Fennoscandian shield and the Khondolite belt occupies the same tectonic position in a Palaeoproterozoic collisional orogen in the North China craton.Comparative analysis of the crustal evolution of the Early Precambrian Belomorian and Trans-North China orogens (Fig. 1) has shown [Slabunov et al., 2015] that: Both belts were formed by the superposition of two Precambrian orogenies.

Studies on correlations between immunophenotype and the indices of metabolic enzyme activity of blood lymphocytes in children with hypertrophy of the pharyngeal tonsils

The objective of our study was to evaluate correlation between the immune pheno-type and activity indices of NAD (P)-dependent dehydrogenases in peripheral blood lymphocytes in young children with hypertrophy of the pharyngeal tonsil (HPT). We have examined 57 children, 1-3 years of age, with hypertrophy of the pharyngeal tonsils (HPT). The control group consisted of 35 healthy children of the same age. The numbers of CD3+, CD4+, CD8+, CD19+, CD16+/56+ lymphoid cells in peripheral blood were determined by flow cytofluorimetry technique. Activity of NAD (P)-dependant dehydrogenases in peripheral blood lymphocytes was studied using bioluminescent method as described elsewhere (А. Savchenko, L. Suntsova, 1989). Correlation analysis has revealed an increase of positive correlations, a decrease of the correlation strength, and emergence of new connections between phenotype and activity indices of NAD (P)-dependent dehydrogenases in peripheral blood lymphocytes in children with hypertrophy of pharyngeal tonsils (HPT). Specific correlation patterns between the phenotype and activity indices of NAD (P)-dependent dehydrogenases in peripheral blood lymphocytes have been revealed in children with hypertrophy of pharyngeal tonsils (HPT)

Systematization of progressive indicators of industrial enterprises' sustainable development

The relevance of the study is conditioned by the modern trends of economic development which suggest that the sustainability of production is possible to provide, while maintaining and enhancing the natural and ecological environment, by looking qualitatively new, revolutionary opportunities, associated with the use of resource-saving and energy-saving technologies, as well as alternative, reproducible sources of industrial activity, the creation of favorable ecological, economic and social conditions for the accumulation and realization of human capital. The purpose of the paper is to systematize progressive indicators of the sustainability of the development of industrial enterprises aimed at increasing the competitiveness of products, the use of innovative energy and resource-saving technologies, minimizing waste generation. The leading method to the study of this problem is the index method, which allows us to consider this problem as a purposeful and organized process to increase the sustainability of the development of industrial enterprises. The paper gives an assessment of the current state of energy consumption of industrial enterprises; a set of progressive indicators of the sustainability of industrial enterprises is suggested. The practical value is that the results of the research make it possible to regulate the sustainable development of industrial enterprises in a better and more targeted way by applying innovative forms of energy and resource saving and can be used in the framework of sector programs, they are of interest to state statistics bodies, as well as ministries and agencies which are responsible for strategic analysis and planning

EPR as a complementary tool for the analysis of low-temperature oxidation reactions of crude oils

© 2018 Elsevier B.V. Air injection is a promising method for enhanced oil recovery (EOR) in both conventional and unconventional oil sources. It is widely accepted that oxidation reactions between oil and injected air determine the success of an air injection process. In this study, electron paramagnetic resonance (EPR) was introduced as a new route to investigate the occurrence of low-temperature oxidation (LTO) and its behavior by monitoring the signals of free radicals. The EPR experiments were conducted for the different crude oil samples (light, medium and heavy) heated in both static air and flow air (air-bubbling) conditions under different temperatures from 25 °C to 180 °C. The results showed that the free-radical concentrations exhibited a good correspondence on the heating temperature. Furthermore, nuclear magnetic resonance (NMR), Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) experiments were carried out to help to analyze the oxidation process and verify the EPR results. It turned out that the EPR results can be well supported by NMR, FTIR and DSC data, which indicates that proposed EPR monitoring method can be applied as a fast and low-cost technique to investigate LTO under mild reaction conditions. Simultaneously, the combination of EPR, NMR, FTIR and DSC can help to better understand the LTO mechanism and to monitor the application of in-situ combustion technique in the field

Extreme sensitivity in Snowball Earth formation to mountains on PaleoProterozoic supercontinents

During the PaleoProterozoic 2.45 to 2.2 billion years ago, several glaciations may have produced Snowball Earths. These glacial cycles occurred during large environmental change when atmospheric oxygen was increasing, a supercontinent was assembled from numerous landmasses, and collisions between these landmasses formed mountain ranges. Despite uncertainties in the composition of the atmosphere and reconstruction of the landmasses, paleoclimate model simulations can test the sensitivity of the climate to producing a Snowball Earth. Here we present a series of simulations that vary the atmospheric methane concentration and latitudes of west–east-oriented mountain ranges on an idealised supercontinent. For a given methane concentration, the latitudes of mountains control whether a Snowball Earth forms or not. Significantly, mountains in middle latitudes inhibited Snowball Earth formation, and mountains in low latitudes promoted Snowball Earth formation, with the supercontinent with mountains at ±30° being most conducive to forming a Snowball Earth because of reduced albedo at low latitudes. We propose that the extreme sensitivity of a Snowball Earth to reconstructions of the paleogeography and paleoatmospheric composition may explain the observed glaciations, demonstrating the importance of high-quality reconstructions to improved understanding of this early period in Earth’s history
