Published: April 2023

The relevance of the study is related to the role of household behavior in the field of energy saving in the context of the development of hydrocarbon energy, in the implementation of energy-saving technologies, the rational use of resources in energy generation, as well as in stabilizing the energy market. The research methodology is based on system and factor analyzes of the neoclassical direction and institutionalism of economic theory, which are ambiguously implemented in shaping the behavior of households in energy saving. The conclusions of the study include highlighting the specifics of the behavior of households in energy saving, the influence of external factors - institutional, infrastructural and others on the rational behavior of households in energy saving. It was stated that the imperfection of the regulatory framework for the provision of energy services and their constant changes limit the formation of rational behavior of households in energy saving. It is suggested that when drawing up an energy-saving policy in the short term, it is necessary to use the factorial theoretical and methodological provisions of neoclassicism, and in the long term to use the factorial approach of institutionalism. The paper analyzes and proposes four models of energy-saving behavior of households and identifies problems and difficulties in the process of their implementation in practice. A factor analysis of the influence of household behavior on the implementation of sustainable energy was also carried out. The transition to sustainable energy, as well as the solution of the problems that stand in its way, must be carried out taking into account the interests and capabilities of households.

Published: April 2023

Ensuring the technological sovereignty of the country, achieving a food independence is associated with the development of the fertiliser market. The conducted research points to the formed market of mineral fertilisers with stable supply and demand, with a focus on export operations. There is no organised market for organic fertilisers in Russia. Production on an industrial scale has not been established, although all the prerequisites are present, in particular, a sufficiently powerful resource and raw material base. During the period from 2009 to 2021, the volume of solid manure decreased from 105.95 million tons to 86.64 million tons, semi-liquid from 117.02 million tons to 109.13 million tons, liquid manure increased from 38.68 million tons to 87.62 million tons. There is an urgent need for the production and application of organic fertilisers, as indicated by the negative balance of humus in the soil from 3.14 to 6.26 million tons d.v. It is proposed to develop an organisational and technological mechanism for the development of the organic fertiliser market. The conceptual apparatus of the mechanism is presented, organisational and technological components are defined. In order to justify the placement of organic fertiliser production, it is proposed to use the optimal localisation of processing enterprises based on the theories of production placement. The technologies of applying organic fertilisers are substantiated, a modern set of technical means developed using high-tech technologies and tested at agar enterprises in the south of Russia is proposed. Full-fledged application of high-quality organic fertilisers contributes to the restoration of soil fertility, increasing the yield of agricultural crops.

Authors: Spektor Ludmila , Agafonova Tatiana
Published: April 2023

The agro-industrial complex is an extensive and comprehensive sector that needs legal regulation for efficiency and legal protection. One of the labor-intensive and complex branches of the agricultural sector in the economy is agriculture. The complexity of economic development through the agricultural sector lies in the instability of climatic conditions in different rural areas of the Russian Federation. Two directions of development of the agro-industrial complex are considered. A new strategy for the development of the agro-industrial complex until 2030 is analyzed. Very careful attention is paid to the goals and directions of this strategy. There are certain strategic risks in the agro-industrial sector. Fluctuations in the economic situation and the application of sanctions by foreign countries create a negative environment for Russia in international trade. Due to the instability of economic and political factors, it can be said that the agro-industrial sector is a risky industry. Therefore, the way out of this situation is insurance of agro-industrial risks. Insurance refers to the protection of property that has suffered damage or loss in certain insurance cases, with the help of insurance funds. In the future, in the author's opinion, the development of insurance in agriculture should be carried out in the following directions: improvement of legislation, namely the adoption of a regulatory act regulating the specifics of insurance in the agricultural sector, taking into account the changed economic conditions.

Authors: Golubova Valentina , Kostylev Pavel
Published: April 2023

The article presents the results of a morphophysiological assessment of rice samples by the strength of growth, as well as an assessment of the degree of development of the conducting system of the flag leaves of rice plants. The resistance of varieties to flooding is very relevant in the fight against weeds due to the deep layer of water that weeds cannot overcome. Currently, there are no zoned varieties in Russia that would meet these requirements. Therefore, the problem of creating such rice varieties is urgent, as it will reduce production costs, reduce grain losses during harvesting, improve the quality of the products obtained, and also reduce the pesticide load on the ecosystem. As a result of research, a number of studied samples revealed the potential to quickly lengthen the first leaves, overcome a large layer of water and accumulate vegetative mass. As a result of the evaluation of the conducting system of the flag leaf of rice plants, it was found that in plants with the flood resistance gene Sub1A, which stops growth under water, the conductive beams were smaller in comparison with other fast-growing samples with the AG, Sk genes. Consequently, fast-growing samples have bigger sizes of the conducting system as a resistance mechanism.

Published: April 2023

The aim of this study is to study engineering safety at an industrial facility. The subject of the study is dangerous and harmful factors of production, which include dust and harmful gases. The objectives of the study is assessing the dispersed composition of dust, which determines the microclimate of the working area on the example of a foundry. The presence of fine dust in the air space of the workshop leads to occupational diseases, such as pneumoconiosis (silicosis), bronchitis, dermatitis, conjunctivitis. The dust dispersion assessment took into account the relationship between the particle size and the speed of movement under the action of gravitational or centrifugal forces. The granulometric composition of the provided powder sample was determined by laser diffraction, implemented on the Fritsch NanoTec “ANALISETTE 22” laser particle analyzer. Data analysis shows that almost all phases of the technological process determine the microclimate of the internal environment and in the inter-hull zone during emission dispersion. The degree of exposure depends on the dispersion and chemical composition of the dust, in particular, in the air, the dust is oxidized to form a SiO2 film. In addition, there are other harmful substances in the workshop air that can be deposited on dust particles, which makes dust more dangerous and in this case it is necessary to take into account more stringent values of maximum permissible concentrations (MPC). An increase in the SiO2 content tightens the requirements for the cleanliness of the air in the working area. In the work, on the basis of theoretical and experimental data, the most dangerous areas with the formation of industrial dust from the standpoint of environmental risk were identified, the dust dispersion was assessed, the dust collection system was finalized, and a wet cleaning system was installed.

The study is devoted to comparing the career orientations of schoolchildren (N=461) from the Omsk region, who have different levels of giftedness, and the search for relationships between their career orientations and migration attitudes. The method of determining career orientations by E. Schein and the scale of migratory attitudes of the individual S.A. Kuznetsova were used. Groups of schoolchildren with reduced and increased educational activity, gifted in one or more areas, were identified. It was found that schoolchildren with reduced educational activity significantly higher than in more active groups developed orientations towards professionalism, autonomy in work, stability of place of residence and work, and the desire to integrate different aspects of life. Migration attitudes of all respondents are expressed at the average level and are negatively related to the orientation towards the stability of the place of residence. The desire to migrate among gifted students has a positive correlation with an orientation towards autonomy in work, among schoolchildren with increased educational activity, in addition, there is a connection with career orientations for managing people and entrepreneurship.
Multiplicative effect as a factor in the development of industrial tourism in the Rostov Region
Authors: Zainullina Tatiana , Kedrova Irina
Published: April 2023

The article conducts a study of the issue of analyzing the multiplicative impact of tourism in general and industrial tourism in particular on the economy of the Rostov region. Tourist spending can have an impact on the economy of the host region through the effect of a direct and indirect multiplier, that is, directly through tourist income and through indirect expenses of tourist enterprises and related industries. The assessment of the multiplier effect of tourism spending on the regional economy is made using the input-output model. Money spent in tourism helps create jobs in tourism directly, but it also indirectly creates jobs in other sectors of the economy. A hotel, for example, has to buy products from local producers, who can spend some of this money on developing production. Tourists often buy souvenirs, which increases employment and production in small businesses. Recognition of the multiplier effects produced by the tourism industry suggests further research in the general context of the economic and social efficiency of tourism at the level of a particular region.

Published: April 2023

At the preclinical stage, a comparative assessment of various models of the formation of oxidative stress by exposure to high and low temperatures, ultraviolet irradiation, and the influence of a low-frequency alternating magnetic field was carried out. Exposure to laboratory animals was carried out daily for 21 days. It has been established that the modeling of oxidative stress by exposure to ultraviolet rays on rats allows, by the end of the first week of the experiment, to induce an increase in the intensity of lipid peroxidation processes with the accumulation of lipid peroxidation products by 48-61% and a decrease in the activity of antioxidant components by 31-33% in comparison with the control, which exceeds similar parameters on day 7 in models of hypothermia, hyperthermia and magnetic induction. Cold exposure in rats is accompanied by a more pronounced shift in the antioxidant status towards the prooxidant side by the end of the third week, which is confirmed by an increase in the concentration of lipid peroxidation products by 45-67% and a decrease in the level of components of the antioxidant system by 28-37% relative to the control. In general, the prooxidant effect in vivo of all the studied effects was confirmed, which we recommend as experimental models for the formation of oxidative stress at the preclinical stage, substantiating in the work the possibility of using each effect depending on the purpose of the pharmacological study.

Published: April 2023

The article notes that after the beginning of the process of developing virgin lands in Kazakhstan in the 1950s, the health authorities faced the question of creating a disinfection station in the city of Tselinograd. The problem in those years was acute, since sewage treatment plants were under construction in the virgin land city and often sewage water was pumped without treatment and discharged into the Taldy-Kul storage lake, located 12 km from the city. The high population density led to an annual increase in the number of infections. The ongoing and final disinfection measures carried out by the health authorities undoubtedly gave certain positive results. However, in infectious diseases hospitals, the regime of chamber disinfection was constantly violated, there were not enough staff, which together lowered the quality of the complex of special measures aimed at destroying pathogens of infectious diseases. The authors of the article came to the conclusion that the measures carried out by the health authorities could not meet the needs of the local and visiting population, and the insufficient organization of the sanitary service was one of the reasons for the high incidence of various infections among the population.

Published: April 2023

The article presents an analysis of the condition of children's healthcare in Molotov city during the Second World War. The authors pay attention to the significant difficulties in protecting the children's health (under one year old): a significant rise in the incidence of childhood infections, malnutrition, incomplete vaccination of children, and a weak level of preventive work. It is emphasized that among nursery and unorganized children respiratory and gastrointestinal diseases were mainly common during the war years: measles, scarlet fever, whooping cough, diphtheria. It is concluded that shortage of qualified medical staff, untimely and partial vaccinations, errors in diagnosis and other reasons have led to an increase in morbidity and mortality among children. In addition, the high incidence of infections with high mortality among children was also associated with the weak and unsatisfactory work of children's consultations on the early detection of diseases which hindered timely treatment.

Published: April 2023

The article presents the results of studies of the influence of luminance modes on ontogenesis of artemia cultivated in artificial conditions in a closed cycle. The aim of the work was to study the effect of light on morphological features of artemia at different stages of ontogenesis. During the work, the luminance modes of 1.5 kl, 2.5 kl and 4 kl were used. It was found that the intensity of the light flux differently affects the ontogenesis and development of individual parts of the body of artemia. In one case, during the cultivation of artemia, optimal results were obtained at 2.5 klx, in the other at 4 klx. The luminance mode of 1.5 klx, turned out to be the least effective. Observations of the growth and development of Artemis larvae in an artificial environment revealed that the luminance mode of 4 klx had a more noticeable stimulating effect on the length of the body, abdomen, cephalothorax and furca than the mode of 2.5 klx at the initial stages of postembryonic development of larvae during the first 120 hours. When cultivating sexually mature artemia, as the results of studies have shown, the luminance mode - 2.5 klx had a more pronounced effect on body length, abdominal length, cephalothorax length, abdominal width and the number of bristles on the furc than the 4klx mode. For the first time, the results of morphological studies demonstrating the effect of light intensity on the development of individual parts of the body of crustaceans in aquaculture have been obtained. The study was supported by the Development Program of the Saratov state university of genetics, biotechnology and engineering named after N.I. Vavilov (Prioritet -2030).

Published: April 2023

The work is devoted to the study of influence of salinity level at the rate of hatching, productivity and morphometric parameters of artemia in aquaculture. The cultivation technology of Artemia salina in aquaculture for obtaining live starter feeds has been used in practice for a long time, but it is still far from perfect, since it is developed for a certain averaged artemia, and in practice we have to deal with specific species and their ecomorphs (ecological morphotypes), the optimal conditions of cultivation of which differ in many ways. One of the most important factors determining the development of artemia is the salinity of the environment. The aim of our study was to assess the effect of the salinity level of culture medium at the rate of hatching, productivity and morphometric parameters of artemia grown in industrial aquaculture. The results of the study showed that with an increase in the concentration of salt in the solution for cultivation of artemia, metamorphosis of the free embryo in nauplia is prolonged and the percentage of their yield decreases. Differences in the average population indicators of length and body weight of nauplia were found, which tended to decrease with an increase in water salt concentration. When studying the absolute fertility of female artemia grown at different concentrations of salt, it was found that an increase in water salinity in reproductive age of females makes it possible to increase their absolute fertility when breeding in artificial conditions.

Financial innovation system reform in Chinese banking: the impact on bank profitability
Authors: Shen Bingbing , Xu Zhenpeng
Published: April 2023

China's innovation capacity has been growing rapidly in recent years, but the country still needs to improve its national innovation system and form a financial services system that is compatible with the full life cycle of science and innovation companies. Looking back at China's history of financial development, the choice and feedback of commercial banks on regulatory policy has been an important factor influencing regulatory policy. With China's financial market gradually opening up to the outside world and an influx of foreign commercial banks, Chinese commercial banks are facing increasing competitive pressure. Improving the profitability of Chinese commercial banks to enhance their competitiveness has become a key to financial innovation and reform in the Chinese banking sector. Therefore, this study investigates the profitability and profit efficiency levels of Chinese banking industry over the period 2012-2020 using stochastic frontier approach. The empirical analysis leads to the following conclusions: The result is that national joint-stock commercial banks and city commercial banks, which have been given more management freedom, are trying to adapt to the dynamically changing environment and show an increase in efficiency. State-owned commercial banks maintain high levels of efficiency, but are more conservative to change. Agricultural commercial banks, for the most part, are showing efficiency gains, with no strong deterioration shown.

Currently, the process of growth and development of cities continues, including through the integrated development of already built-up areas, in connection with which there is a problem of intensification of the use of their territory. Objects of cultural heritage, as objects of everyday life of people of past historical epochs, occupy the most valuable territories in terms of urban planning. At the same time, a large number of cultural heritage sites are not included in the life of the city, because they are in an accident condition and have strict regulations for use and transformation. The article provides an example of an algorithm for working with an object of cultural heritage in order to adapt it for use as a social object in the conditions of complex development of the territory (renovation). The type of social object is determined taking into account the priority in the renovation conditions in two stages.

Revolutionary technological development has been assumed to be the cause and basis of the same revolutionary changes in the modern environmental perception of youth. The purpose of the article is to show the changes in youth's sustainable perspectives on environmental issues via information and communication technologies and the changes in sustainable behaviour. The methodology of this study presents the analysis of related topics and qualitative research based on the online questionnaire. The collection of data helped to show that over 80 per cent of modern digital youth use information and communication technologies to raise their awareness of environmental concerns and their preference for the environmental issues that attract them the most by watching or reading the news online. The model of three variables ”awareness – attitude – behaviour”, was proposed. This model can be used to explain influencers and modes of action in the emotional domain of environmentally sustainable behaviour among young people. The study of changes in sustainable behavior based on the example of language and emotional domains in the era of information and communication technologies and may supplement existing research. Research may be of interest to philosophers, psychologists, sociologists, linguists and those concerned with the environmental issues.

Background In type 2 diabetes, insulin resistance is observed, and
β-cells are incapable of responding to glycemia demands, leading to
hyperglycemia. Although the nature of β-cells dysfunction in this
disease is not fully understood, a link between the induction of pancreatic
β-cell premature senescence and its metabolic implications has been
proposed. This study aimed to understand the relationship between diabetes and
pancreatic senescence, particularly at the beginning of the disease.

Methods C57Bl/6 J mice were fed two different diets, a
normal diet and a high-fat diet, for 16 weeks. Pancreatic histomorphology
analysis, insulin quantification, inflammation parameters, and senescence
biomarkers for the experimental animals were assessed at weeks 12 and 16.

Results The results proved that diabetes onset occurred at week 16 in the
High Fat Diet group, supported by glycaemia, weight and blood lipid levels.
Increased β-cells size and number accompanied by increased insulin
expression were observed. Also, an inflammatory status of the diabetic group was
noted by increased levels of systemic IL-1β and increased pancreatic
fibrosis. Finally, the expression of galactosidase-beta 1 (GLB1) was
significantly increased in pancreatic β-cells.

Conclusion The study findings indicate that senescence, as revealed by an
increase in GLB1 expression, is a key factor in the initial stage of
diabetes.
Cryofibrinogen—Characteristics and Association with Cryoglobulin: A Retrospective Study Out of a Series of 1,712 Samples over 7 Years
Authors: Sarda-Kolopp Marie N. , Miossec Pierre
Published: April 2023

Objective Cryofibrinogens (CFs) and cryoglobulins (CGs) are cryoproteins responsible for obstructive vasculopathy and vasculitis. The aim of this study was to compare the characteristics of CF and CG, and to define the conditions of their association.

Methods and Results This retrospective study was conducted at the Lyon University Hospitals, and included patients with at least one sample tested for CF and/or CG between September 2013 and April 2021. Serum and plasma samples were analyzed in very strict conditions of temperature. After cold precipitation, CF and CG were characterized and quantified in the cryoprecipitates. CRP and plasma fibrinogen levels were also investigated. Over this 7-year period, 1,712 samples for CF detection and 25,650 samples for CG detection were sent to the laboratory. Simultaneous testing of CF and CG was performed in 1,453/1,712 samples (85%). CF was less often positive than CG (8.3 vs. 13.5%, p < 0.0001). In positive CF samples, CG was associated in 28.9% of cases. In CF, fibrinogen was associated with fibronectin in 98/142 (69%) samples, especially in highly concentrated CF. CF concentration was independent of C-reactive protein and plasma fibrinogen concentrations.

Conclusion The simultaneous detection of CF and CG is essential for the diagnosis of vasculitis or thromboembolic events and their treatment.

Urinary Bladder Mullerianosis Causing Recurrent Abdominal Pain: A Rare Case Report and Review of the Literature
Authors: Kumar Manjeet , Barwal Kailash Chander , Sharma Girish Kumar , Mardi Kavita , Raina Pamposh , Sharma Sanjeev
Published: April 2023

Mullerianosis of the urinary bladder is a rare bladder lesion with fewer than 30 cases reported in the literature. It describes the ectopic presence of endocervical, endometrium, and endosalpingial tissues inside the urinary bladder. It is diagnosed when at least two of three Mullerian tissues, endometriosis, endocervicosis, and endosalpingiosis, are identified. Mullerianosis presents in females of the reproductive age group, especially after pelvic surgery. Treatment involves resection of the bladder mass and ruling out malignant pathology. Follow-up of Mullerianosis is vital, as recurrence is common. Medical therapy is also indicated when a diagnosis is established after the histopathological examination of the tumor.

We report a 31-year-old female presenting with recurrent lower abdominal pain. Cystoscopy showed a mass of 3 × 3 cm in the urinary bladder. Transurethral resection of bladder tumor was resected, and histopathology suggested a combination of endometriosis, endocervicosis, and endosalpingiosis. Pain was resolved after surgery, but the lesion recurred at 3 months, which was subsequently resected.
