PRINCIPLES OF THE "GREEN" ECONOMY IN RUSSIA: CURRENT STATE, COMPARING WITH WORLD EXPERIENCE, CHALLENGES AND PROSPECTS
Background: The concept of sustainable development plays an essential role in the functioning of the modern world economy. An important component of this concept is the implementation and financing of "green" and socially-oriented projects. In Russia, this direction is only at the initial stage of its formation, therefore it is important to study it and find ways to accelerate its development. Objective: The purpose of the research is to analyze the current state of sustainable development projects financing in Russia, to identify its features and future prospects, as well as to find the most effective ways for its development. Methods: To accomplish this task, the article analyzes the dynamics of changes and key trends in the global and Russian sustainability financial markets. Their comparative analysis is carried out, the main similarities and differences are highlighted. Results: Attention is paid to both industry and subtypes distribution. The theoretical basis of the sustainable development market formation is also considered, its impact on the ESG agenda in Russia is assessed. In the final part, forecasts are made for the possible development of the international and Russian ESG markets. The most effective ways of evolving the sustainable development concept in Russia are identified. Particular attention is paid to the DeFi technologies introduction possibility to simplify and improve financing mechanisms and the implementation of "green" and socially-oriented projects
THE EVALUATION OF FUNDAMENTAL METHODS EFFECTIVENESS ON THE RUSSIAN STOCK MARKET
Objective: The purpose of the study is a comparative analysis of various fundamental analysis indicators and indicators based on expected levels of return and risk usage. The aim also lies in identifying the most promising of them in the current state of the modern Russian stock market.

Both the effectiveness of individual indicators and the methods of their application are compared; index and average levels of profitability are added as an additional basis for comparison. For the purposes of the study, historical data from 2015 to mid-2021 is considered; portfolios are formed as of the first trading day of each year, starting from 2017. Results: Based on the results of the study, recommendations for traders on the use of the considered indicators were formed. Conclusion: The novelty of the study is the obtained results of comparing the effectiveness of individual groups of indicators used in compiling a portfolio in the modern state of the Russian stock market
OSCILLATOR STRATEGIES APPLICATION IN STOCK MOVEMENT PREDICTION ON THE RUSSIAN FINANCIAL MARKET: EFFICIENCY ISSUES
Background: Technical analysis is one of the most frequently used by traders instruments. However, many of its elements (in particular oscillators) may show varying efficiency depending on the particular markets characteristics. Therefore, taking into account the distinctive features of the Russian stock market, it is reasonable to examine which oscillators can be effectively applied on it. Objective: The purpose of the study is to analyze the effectiveness of technical analysis indicators for forecasting shares of the Russian stock market and to develop the most effective trading strategy combining various oscillators. Methods: In order to achieve this, the selection of stocks suitable for testing and technical analysis indicators representing various groups is carried out. The accuracy and the total number of signals act as criteria for the indicators effectiveness, while accuracy is given the main attention. The interval from mid-2020 to mid-2021 is used for testing. Results: Based on the results obtained, the indicators are divided into efficiency groups; recommendations for the application of each oscillator are given. The result of the study is the development of the most effective strategies for the usage of technical analysis indicators that have passed the test. The strengths and weaknesses of each formed strategy are highlighted. Conclusion: The novelty of the research lies in obtaining the results of comparing the different types of technical analysis indicators effectiveness in the modern conditions of the Russian stock market and in building optimal strategies for their application
Microstructural and material property changes in severely deformed Eurofer-97
Severe plastic deformation changes the microstructure and properties of
steels, which may be favourable for their use in structural components of
nuclear reactors. In this study, high-pressure torsion (HPT) was used to refine
the grain structure of Eurofer-97, a ferritic/ martensitic steel. Electron
microscopy and X-ray diffraction were used to characterise the microstructural
changes. Following HPT, the average grain size reduced by a factor of
30, with a marked increase in high-angle grain boundaries. Dislocation density
also increased by more than one order of magnitude. The thermal stability of
the deformed material was investigated via in-situ annealing during synchrotron
X-ray diffraction. This revealed substantial recovery between 450 K - 800 K.
Irradiation with 20 MeV Fe-ions to 0.1 dpa caused a 20% reduction in
dislocation density compared to the as-deformed material. However, HPT
deformation prior to irradiation did not have a significant effect in
mitigating the irradiation-induced reductions in thermal diffusivity and
surface acoustic wave velocity of the material. These results provide a
multi-faceted understanding of the changes in ferritic/martensitic steels due
to severe plastic deformation, and how these changes can be used to alter
material properties.Comment: 59 pages, 19 figure
Dose and compositional dependence of irradiation-induced property change in FeCr
Ferritic/martensitic steels will be used as structural components in next generation nuclear reactors. Their successful operation relies on an understanding of irradiation-induced defect behaviour in the material. In this study, Fe and FeCr alloys (3–12%Cr) were irradiated with 20 MeV Fe-ions at 313 K to doses ranging between 0.00008 dpa to 6.0 dpa. This dose range covers six orders of magnitude, spanning low, transition, and high dose regimes. Lattice strain and hardness in the irradiated material were characterised with micro-beam Laue X-ray diffraction and nanoindentation, respectively.
Irradiation hardening was observed even at very low doses (0.00008 dpa) and showed a monotonic increase with dose up to 6.0 dpa. Lattice strain measurements of samples at 0.0008 dpa allow the calculation of equivalent Frenkel pair densities and corrections to the Norgett-Robinson-Torrens (NRT) model for Fe and FeCr alloys at low dose. NRT efficiency for FeCr is 0.2, which agrees with literature values for high irradiation energy. Lattice strain increases with dose up to 0.8 dpa and then decreases when the damage dose is further increased. The strains measured in this study are lower and peak at a larger dose than predicted by atomistic simulations. This difference can be explained by taking temperature and impurities into account

Problem of chronic endometritis in cows and ways to solve it
Chronic endometritis is diagnosed on average in 18.1 % of infertile cows. With chronic endometritis, the uterus has a pronounced cavity of 18.4±0.9 mm (11–35 mm), while the wall thickness of the uterus is on average 8.7±0.37 mm. Morphometrically chronic endometritis is characterized by a decrease in the fraction of functionally active elements of the endometrium (integument epithelium, uterine glands, blood vessels) to 12.17 %. In the development of chronic endometritis, cows compared with clinically healthy animals showed an increase in leukocyte content by 12.2 %, monocytes by 2.5 times, creatinine by 29.7 %, average molecular peptides by 25.0 %, and endogenous intoxication index by 25.4 %, circulating immune complexes by 38.5 %, with a decrease in the bactericidal and lysozyme activity of blood serum, respectively by 10.7 and 12.9 % and phagocytic activity of leukocytes by 12.4 %. The effectiveness of the application of the developed method for the treatment of chronic endometritis, involving the use of aminoseleton five times with a 72-hour interval at a dose of 30, 35, 40, 45 and 50 ml, magestrofan on the 1st and 13th days at a dose of 2 ml, uterotone on 3rd, 4th and 5th days at a dose of 10 ml and intrauterine administration of primalact on 1st-3rd days at a dose of 20 ml, is 88.0 %. Recovery of animals after the treatment is accompanied by a decrease in the inflammatory response, endogenous intoxication, normalization of liver and kidneys, an increase in overall non-specific resistance and a decrease in uterine microbial contamination
