Natural populations of crayfish are in depression in Russia and local species are not cultivated. In this situation, experimental cultivation of allochtonous australian crayfish Cherax quadricarinatus is conducted. This species is distinguished by high reproductive abilities and good consumer properties. It has domesticated in Russia spontaneously and produced 9–10 generations in Astrakhan Region. Certain natural selection in the process of domestication provides adaptive ability of this species to local environments and its capabil­ity to reproduce a viable progeny, so there is no doubts in good prospects of its cultivation in industrial conditions.

Development of low-growing varieties is one of the prioritized directions in groups selection. Solution of excessive growth in the selection can be solved in today’s conditions by two means: on a polygenic and on a monogenic level. Up until recently such work was performed by research institutes of horticulture in the U.S.S.R. and Russian Federation only on the polygenic level. The analysis is performed for the data of 17 summer studies on the development of complex donors of monogenic determined dwarfness (gene D), high winter hardiness, group fungal disease resistance (scab, leaf spot and Septoria blight) and bright red coloration of pear fruits (gene C). On the first stage of these studies the issue of the development of population of hybrid dwarf types with high adaptive potential in the conditions of the Central Black Earth region of Russia was solved based on a hybridization of the donors of high winter hardiness and fungal disease resistance with the donors of monogenic determined dwarfness which were the descendants of 4th generation of the NainVert variety. As a result, several complex donors were selected. Its use in long-term pear selection programs would make sorting process possible on earlier stages of the ontogenesis and thanks to that would make it possible to halve the size of hybrid funds. Brief description of the complex donors is given.

The Disappeared

The article deals with the problem of collecting, preserving and researching the disappeared names of localities in the subjects of the Russian Federation, which for centuries have become an integral part of the historical and cultural heritage of the peoples of our country. The author believes that only a comprehensive analysis of the past oikonyms in nominational, lexical-semantic, historical-cultural, historical-ethnographic, local history aspects will restore the linguistic and cultural systems of different time periods in different microareals of the Russian Federation. The author comes to the conclusion that in order to preserve the historical memory of the disappeared names of geographical objects, local researchers need the support of regional state authorities and local self-government.

The presented study develops theoretical and methodological foundations for assessing the fiscal sustainability of the constituent entities of the Russian Federation in perspective.Aim. The study aims to develop a systems approach to assessing the fiscal sustainability of the constituent entities of the Russian Federation in the medium and long term.Tasks. The authors analyze the major approaches to assessing the fiscal sustainability of federal subjects and determine the significance of quantitative and qualitative assessment methods in the development of a methodology for assessing the fiscal sustainability of federal subjects in the medium and long term.Methods. This study uses scientific methods of cognition, analysis and synthesis, comparison and analogy, systems and institutional approaches to assess the fiscal sustainability of federal subjects.Results. The authors examine the major approaches to assessing the fiscal sustainability of federal subjects developed by Russian scientific schools and disciplines; approaches used by state and local authorities; approaches to assessing the fiscal sustainability of federal subjects used by international and national rating agencies; foreign experience. In general, this implies the development of a universal system of indicators for assessing the fiscal sustainability of federal subjects.Conclusions. It is substantiated that under the current conditions of new challenges, particularly in the context of the coronavirus pandemic, it is necessary to assess the long-term balance and sustainability of the budgets of federal subjects using a systems approach based on quantitative and qualitative methods, making allowance for the medium- and long-term prospects to make efficient management decisions at different levels of the economic system.

The Common

The steel fiber/graphite conductive concrete is applied in power system grounding. In high soil resistivity regions, the common methods for reducing the grounding resistance are not practical. It is difficult for grounding resistance of substations to meet the requirements of working earthing and safety earthing. In order to solve this problem, a steel fiber/graphite conductive concrete is developed in this paper. Steel fiber and graphite are added as conductive fillers. The long-term stability of the steel fiber/graphite conductive concrete is studied. The experiment results show that steel fiber/graphite conductive concrete not only maintains excellent conductivity, but also has good mechanical strength and corrosion resistance in 300 days.
