Influence οf households’ borrowings οn consumer spending during the escalation of the crisis

This article investigates the relationship between the borrowing activity of Russian households and their current conumer expendatures in the period of escalation of the social and economic crisis. The analysis was conducted on the basis of data provided by the Russian Longitudinal Monitoring Survey, RLMS-HSE for 2015. The paper proposes and implements an approach that makes it possible to assess the impact of borrowings on inequality in consumption and poverty among households. It was revealed that the need of repayment results in saving on food, medical treatment and other vital needs for an overwhelming number of households. This is especially acute among families being beyond the poverty threshold.peer-reviewe

Purpose: to develop the methodology for risk-assessment of the potential hazard of the Rostov region’s territory due to anthrax based on the spatial analysis, independent of the administrative division.Materials and Methods: for development the risk-based assessment of potential hazards of territory due to anthrax the registration data of cases for 132 years have been used. The construction of risk cartograms were carried out on the basis of biweight distribution of stationary unfavorable places due to anthrax.Results: the average value of the epizootic index and density of stationary unfavorable places due to anthrax are calculated for 413 administrative units of the Rostov region.Summary: the identification of «risk areas» by using risk-based methodology would provide the more accurate results than the zoning due to administrative territories

DEVELOPMENT OF SPATIAL ANALYSIS TECHNIQUES FOR IDENTIFICATION OF "RISK AREAS" IN CASE OF EXTERNAL THREATS REALIZATION AS REGARDS SANITARY AND EPIDEMIOLOGICAL WELLFARE

Objective of the study was to develop the methodology for identification of administratively independent areas under potential risk of “external” epidemiological threat realization, by the example of cholera.Materials and methods. Analysis was conducted using free software package with open source code (QGIS 2.8 and GRASS GIS 7.0) on the basis of the data received from Rosgranitsa and the Federal State Statistics Service. The construction of risk cartogram was performed on the base of Euclidean distance and estimation of nuclear density.Results and conclusions. In accordance with the obtained results, the GIS containing information about the checkpoints on the Russian border, settlements, roads and railway lines was worked out. The method of identification of risk areas due to importation of infectious diseases based on the cholera model has been developed, and the total area of such territories was less than 1 % of the total area of the country. It was found that in some cases the risk area is located at a certain distance from the checkpoint, but the existence of checkpoint does not lead to the formation of risk areas. The developed GIS is available on the geo-information portal of FGHI Rostov-on-Don Research Anti-Plague Institute of Rospotrebnadzor

Results of epizootic monitoring of natural foci of particularly dangerous infections common to humans and animals in Rostov Oblast

Objective: To analyze the results of epizootic monitoring of natural foci of particularly dangerous infections common to humans and animals in Rostov Oblast to establish their activity.Materials and Methods: The data of epizootic monitoring conducted by zoologists; the results of laboratory research of field material obtained in natural foci of infectious diseases. Descriptive, zoological, genetic, serological methods, and retrospective epidemiological analysis were used.Results: The results of the conducted epizootic monitoring showed the presence in Rostov Oblast of natural foci of particularly dangerous infectious diseases common to humans and animals. While the natural focus of the plague is in a depressed state and does not show activity, in the foci of tularemia, West Nile fever (WNF), Crimean hemorrhagic fever (CHF), ixodic tick-borne borreliosis (ITB), hemorrhagic fever with renal syndrome (HFRS), Q fever, Batai fever, California serogroups, Syndbis revealed the antigens of these pathogens in biological material obtained from small mammals and blood-sucking insects, which indicates the epizootic activity of these foci. In the natural foci of WNF, CHF, ITB, HFRS, cases of these disease among the population were recorded, which confirms the epidemic activity of these foci.Conclusion: The obtained results of epizootic monitoring over the period from 2008 to 2020 emphasize the relevance and necessity of continuing these studies in natural foci in Rostov Oblast

Study of the State of Carbon Regulation and Perspectives for Russia

This article aims to investigate the current state of the problem of carbon regulation in the world and to discuss the general concept of carbon regulation in Russia. The main mechanisms and approaches to regulating greenhouse gas emissions in the international aspect are considered. It is concluded that under conditions of transboundary carbon regulation it is important to move to preactive actions in the framework of climate policy and to focus on support of domestic economy competitiveness. Studies of the conceptual foundations of the application of economic instruments in the fight against carbon emissions are carried out by a significant number of domestic and foreign scientists. Standard methods of taxation and collection underlie carbon taxation policy as a useful tool for resource management and environmental protection. A carbon tax is one of the economic tools for regulating greenhouse gas emissions. An emissions tax puts a price on a unit of emissions thereby creating incentives for emitting companies to reduce them. It is currently used in over 40 countries around the world in one form or another

Cytology of the minor-vein phloem in 320 species from the subclass Asteridae suggests a high diversity of phloem-loading modes†

The discovery of abundant plasmodesmata at the bundle sheath/phloem interface in Oleaceae (Gamalei, 1974) and Cucurbitaceae (Turgeon et al., 1975) opened the questions whether these plasmodesmata are functional in phloem loading and how widespread is symplasmic loading. Analysis of over 800 dicot species allowed the definition of ‘open’ and ‘closed’ types of the minor vein phloem depending on the abundance of plasmodesmata between companion cells and bundle sheath (Gamalei, 1989; 1990). These types corresponded to potential symplasmic and apoplasmic phloem loaders, respectively; however, this definition covered a spectrum of diverse structures of phloem endings. Here, a review of detailed cytological analyses of minor veins in 320 species from the subclass Asteridae is presented, including data on several cell types and their combinations which have not been reported previously. The percentage of Asteridae species with ‘open’ minor vein cytology which also contain sieve-element-companion cell complexes with ‘closed’ cytology, i.e. that show specialization for both symplasmic and apoplasmic phloem loading, was determined. Along with recent data confirming the dissimilar functional specialization of structurally different parts of minor vein phloem in the stachyose-translocating species Alonsoa meridionalis (Voitsekhovskaja et al., 2009), these findings suggest that apoplasmic loading is indispensable in a large group of species previously classified as putative symplasmic loaders. Altogether, this study provides formal classifications of companion cells and of minor veins, respectively, in 24 families of the Asteridae based on their structural features, opening the way to a close investigation of the relationship between structure and function in phloem loading

Phloem Loading in Two Scrophulariaceae Species. What Can Drive Symplastic Flow via Plasmodesmata?

To determine the driving forces for symplastic sugar flux between mesophyll and phloem, gradients of sugar concentrations and osmotic pressure were studied in leaf tissues of two Scrophulariaceae species, Alonsoa meridionalis and Asarina barclaiana. A. meridionalis has a typical symplastic configuration of minor-vein phloem, i.e. intermediary companion cells with highly developed plasmodesmal connections to bundle-sheath cells. In A. barclaiana, two types of companion cells, modified intermediary cells and transfer cells, were found in minor-vein phloem, giving this species the potential to have a complex phloem-loading mode. We identified all phloem-transported carbohydrates in both species and analyzed the levels of carbohydrates in chloroplasts, vacuoles, and cytoplasm of mesophyll cells by nonaqueous fractionation. Osmotic pressure was measured in single epidermal and mesophyll cells and in whole leaves and compared with calculated values for phloem sap. In A. meridionalis, a 2-fold concentration gradient for sucrose between mesophyll and phloem was found. In A. barclaiana, the major transported carbohydrates, sucrose and antirrhinoside, were present in the phloem in 22- and 6-fold higher concentrations, respectively, than in the cytoplasm of mesophyll cells. The data show that diffusion of sugars along their concentration gradients is unlikely to be the major mechanism for symplastic phloem loading if this were to occur in these species. We conclude that in both A. meridionalis and A. barclaiana, apoplastic phloem loading is an indispensable mechanism and that symplastic entrance of solutes into the phloem may occur by mass flow. The conditions favoring symplastic mass flow into the phloem are discussed
