Agricultural Sector of Ulyanovsk Region (1966-1970): A Focus on Crop Production

This article provides a comprehensive analysis of the modernization processes in the crop production sector of the Ulyanovsk region during the Eighth Five-Year Plan. The research draws on unpublished documents sourced from the State Archive of the Ulyanovsk Region and the State Archive of Contemporary History of the Ulyanovsk Region, a significant portion of which is introduced into scholarly discourse for the first time, alongside statistical materials and periodicals. The study examines the efforts of party organs and farm leadership aimed at intensifying the development of crop production. It addresses the authorities’ personnel policies regarding the expansion of vocational and technical education institutions, the organization of training courses for specialists in mass professions, and the enhancement of their qualifications to meet agricultural needs. The dynamics of crop production development from 1966 to 1970 are analyzed, evaluating the achievements of regional farms in producing key agricultural products. The author concludes that, despite facing problematic farms and a slight reduction in areas allocated for grain crops, the authorities in the Ulyanovsk region managed not only to meet but also to exceed the planned targets for yield, total harvest, and state procurement volumes of primary crop products during this period.

Comparative Analysis of Surgical Outcomes in Hybrid and Open Esophagectomy for Esophageal Cancer: A Regional Russian Cancer Centre Experience.

Surgery is pivotal in treating esophageal cancer; hybrid esophagectomy, which combines minimally invasive and open techniques, shows promising outcomes. This historical cohort study compared the surgical outcomes of standard open esophagectomy with hybrid esophagectomy. Overall, 58 patients who underwent either hybrid or open esophagectomy at the Ulyanovsk Regional Clinical Oncology Clinic, Russia, from January 2015 to December 2023 were included. Data on demographics, surgical details, and postoperative outcomes were analyzed. The primary measures were overall complications and anastomotic leakage rates. Statistical analysis was performed using Pearson's Chi square test and t test via StatTech software (version 2.8.8). The number of removed lymph nodes was higher in the hybrid group (24±9) than in the open group (15±7) (P<0.001). In addition, the hybrid esophagectomy group showed significant reductions in operational time and blood loss (P<0.001 and P=0.014, respectively). The need for blood transfusion was higher in the open esophagectomy group (P=0.043). The postoperative length of stay in the hospital did not differ significantly between the two groups (open=20±8 days, hybrid=17±7 days, P=0.178). Cardiac complications were more frequent after an open esophagectomy (P=0.044). Hybrid esophagectomy reduced postoperative cardiac complications and other adverse events while maintaining satisfactory oncological outcomes. It had advantages over standard open esophagectomy in terms of lymphadenectomy, operative time, blood loss, and transfusion requirements, suggesting its efficacy for esophageal cancer patients.

Assessment of the adaptive capacity of children and adolescents in environmentally challenging conditions

BACKGROUND: A number of recent studies have demonstrated an increase in the number of children and adolescents with deviations in physical development attributing this increase to the effects of environmental pollution. The ability of children and adolescents to adapt to their environment can serve as an indicator of their physical development in unfavorable environmental conditions. AIM: To assess the physical development and adaptive capacity of children and adolescents living in regions with varying degrees of anthropogenic impact on the environment. MATERIAL AND METHODS: An analysis of the environmental situation in the Ulyanovsk region was carried out based on the author’s own research of atmospheric air, drinking water and soil samples collected from residential areas in 2009–2023. The study focused on identifying pollutants in the natural environment and calculating a comprehensive pollution indicator for each environmental component. In addition, a survey of schoolchildren in the Ulyanovsk region was conducted. Height, weight, chest circumference, body mass index, heart rate, systolic and diastolic blood pressure were measured. The adaptation capacity (AC) of the study participants was calculated using the Baevsky formula. RESULTS: Schoolchildren of both genders, who lived in regions with low level of anthropogenic impact on the environment, had higher values for morphological and functional characteristics than schoolchildren in regions with high degree of anthropogenic impact. Median AC values for boys and girls in the latter group were higher than those in the former, suggesting heightened adaptation mechanisms in environmentally disadvantaged areas. The differences in AC among girls closely mirrored those observed in boys, albeit across fewer age-groups, potentially indicating greater adaptive reserves in the latter group. CONCLUSION: Our findings can be used for sanitary and hygienic monitoring, prevention of childhood morbidity and the development of environmental strategies to reduce the adverse effects of environmental factors on public health.

Employment and development levels in rural areas of the Russian Federation

The development of agro-industrial complex is important for ensuring national food security and national health. The development of rural areas is subject to the development of agriculture and local infrastructure, as well as the availability of various services. This study selected 15 indicators in 2021 to analyze the employment and development levels in rural areas of 71 regions of the Russian Federation using the analytical grouping method. The results indicated that 20 regions (Group 1) had the highest percentage of rural population (33.10%). The percentage of population engaged in agriculture had the highest value (12.40%) in 31 regions (Group 2). Moreover, 20 regions (Group 3) had the highest investments in fixed assets at the expense of municipal budget (11.80 USD/person). Increasing the investments in fixed assets carried out from the budget of the municipality can improve the employment level in rural areas. Then, we used cluster analysis to divide 14 regions of the Volga Federal District in the Russian Federation into 3 clusters. Cluster 1 covered Kirov Region and Republic of Mari El; Cluster 2 included Ulyanovsk Region, Saratov Region, Nizhny Novgorod Region, Perm Territory, Orenburg Region, Chuvash Region, and Republic of Mordovia; and Cluster 3 contained Republic of Tatarstan, Samara Region, Udmurtian Republic, Penza Region, and Republic of Bashkortostan. Results indicated that the 2 regions of Cluster 1 need to increase the availability of resources and natural gas and improve the investment attractiveness of rural areas. The 7 regions of Cluster 2 needed to develop infrastructure, public services, and agricultural production. We found the highest employment level in rural areas, the largest investments in fixed assets at the expense of municipal budget, the largest residential building area per 10,000 persons, and the largest individual residential building area in the 5 regions of Cluster 3. This study makes it possible to draw up a comprehensive regional development program and proves the need for the development of rural areas, which is especially important for the sustainable development of the Russian Federation.

Methodological Aspect of Evaluating the Effectiveness of Public Policy in Depressed Regions

The paper considers the practical possibilities of using various methods of qualitative and quantitative assessment of the effectiveness of public policy implementation, detailed in the context of the problem of depressed regions rehabilitation. The aim of the study is to form a holistic and comprehensive model that allows analyzing the effectiveness of the implementation of state projects at the regional level, taking into account the specific features inherent in the economic and administrative spheres of the depressed subjects of the Russian Federation. The relevance of the research topic to these conditions is defined by the dynamic nature of the development of regional depression, as well as the need to improve public administration mechanisms in order to solve urgent problems of socio-economic development of regions and ensure opportunities for sustainable and balanced spatial development of the Russian Federation. The development of this topic includes the use of methods of retrospective statistical analysis, mathematical modeling, as well as abstraction and socio-economic comparison. Based on the results of the study, a theoretical concept has been formed, including a methodological apparatus that allows evaluating the effectiveness of existing models of public administration for the development of depressed regions. The conclusions obtained at the theoretical level are concretized in the context of a practice-oriented analysis of the state and prospects of development of the depressed region — the Ulyanovsk region; the results of the analysis fully prove the validity of the proposed methodological developments. Based on the results of the study, a number of practical conclusions were made, in particular, in the context of analyzing the effectiveness of public policy, the role of integrated non-financial quantitative assessment tools was updated, as well as a number of aspects of their practical application and further improvement were specified. The prospects for further use of the proposed evaluation model are related to the possibility of its implementation into the structure of software and analytical complexes currently used in public administration practice. The results of the study are of practical importance in the context of the possibilities of optimizing the control and evaluation functions of public authorities and, in particular, can be used by subjects of state strategic planning for the formation and subsequent assessment of territorial development plans of the Russian Federation.

USAGE OF TECHNICAL MEANS FOR ANNULAR GAS EXTRACTION TO INCREASE OIL WELL PRODUCTION

In recent years, the technology of annular gas extraction from wells has become increasingly widespread in the fields in order to improve the working conditions of the submersible pump due to increasing its filling and supply coefficients, as well as increasing depression on the formation. Some types of compressor designs have been developed and put into production, allowing the annular gas extraction from wells and forced injection into the pressure line of the well. One of the most well-known types of compressors is a piston pair driven by a piston from a rocking machine balancer. They were used at oil production facilities in the Orenburg, Ulyanovsk Regions, the Republics of Tatarstan and Bashkortostan, Udmurtia and other regions of the Russian Federation.In the fields of Sheshmaoil LLC, a complex for pumping gas from the annulus of a well and pumping it into the COGS product collection system has found mass usage, allowing gas to be taken from a group of wells and reducing pressure in the annulus to values close to 0.1 MPa. Hydraulic piston compressors, in which gas compression occurs using a high-pressure pump that drives the piston group of the compressor, have been tested.One of the main disadvantages of the developed types of compressors is the insufficient volume and pressure of the compressed gas. The article provides an analysis of the technological parameters of the compressors. As a result of research possible solutions to the problem are worked out.To achieve the largest pumping volumes of separated annular gas, the maximum permissible diameter of the compressor cylinder should not exceed 0.07 m in order to prevent significant resistance exerted by the piston rod on the balancer of the pumping machine.The most suitable region for the effective use of suspended compressors is the Ural-Volga Region at fairly depleted oil fields with at least 60–65 % water cut, oil well flow rate of no more than 10–15 tons/day and a gas factor of no more than 15–20 m3/t . At the fields of Western Siberia, suspended compressors cannot be used due to high flow rates and gas factors. Exceptions may be wells with a water cut of at least 80 % and flow rates of no more than 20–25 tons/day.The KOGS compressor unit, developed and widely implemented at Sheshmaoil Management Company LLC, showed positive results, consisting of an increase in flow rate and additional oil production. For further use of the unit in fields, especially for high-viscosity oil production, as well as operation in winter conditions, it is necessary to increase the maximum gas injection pressure.

Prediction of the harmfulness of bristle species in agrophytocenoses with spring barley

Relevance. The appearance of weeds in the fields of farms does not always imply their complete destruction, since from an economic point of view this may be ineffective. Therefore, in order to predict the effectiveness of crop contamination control in specific soil and climatic conditions, an urgent task is to develop and substantiate models of weed harmfulness and calculate economic thresholds for their harmfulness.Methods. The harmfulness of gray bristle (Setaria glauca (L.) Beauv) and green bristle (Setaria viridis (L.) Beauv) in the conditions of the Agro-Invest Plus LLC enterprise in the Karsunsky district of the Ulyanovsk region in 2021–2022 on the yield of Despina barley was studied. The economic harmfulness thresholds were calculated against the background of the use of herbicides Ovsyugen Super, CE — 0.5 l/ha; Axial 50, CE — 0.9 l/ha; Puma Super, EMV — 0.9 l/ha; Avantik Turbo, MD — 0.5 l/ha. The scheme of the experience included: Option 1 — without weeds (control), 2–6 options — with the number of weeds, respectively, 10 pcs/m2, 20 pcs/m2, 30 pcs/m2, 40 pcs/m2, 50 pcs/m2, option 7 — with natural blockage. The accounting area of the plot is 1 m2, the location is systematic with an offset, the repetition is 6 times.Results. Based on field experiments, predictive models have been developed to determine the harmfulness of weeds, which make it possible to establish economic thresholds for their harmfulness in the conditions of a particular farm. The harmfulness of the bristle according to the linear function was 0.106–0.147 c/ha, depending on the amount (pcs/m2) or 0.322–0.291 c/ha by weight (g/m2). According to prognostic models, the proportion (%) of changes in barley grain yield from contamination ranged from 79 to 85%. Studies have shown that chemical weeding is advisable in the presence of bristles in barley phytocenoses from 8 to 15 pcs/m2.

ASSESSMENT OF ECOLOGICAL PROCESSES IN THE SVIYAGA RIVER (ULYANOVSK REGION)

The Sviyaga River is a water resource, and a recreational facility. It is rich in fish, therefore the assessment of ecological processes in the Sviyaga river is relevant and has theoretical and practical significance. The relevance and practical significance of research is increasing due to the plans to use the Sviyaga river bays for aquaculture development.&#x0D; The purpose of the study was to examine the nature and direction of ecological processes in the Sviyaga River bays on the territory of the Ulyanovsk region.&#x0D; Materials and Methods. The assessment of the bay water quality was carried out according to organoleptic, hydrochemical and hydrobiological parameters.&#x0D; Results. Organoleptic water parameters in both bays met the requirements for natural waters. The maximum water temperature in summer reached 24–26 ºС, the average temperature was 20.5 ºС. The amount of dissolved oxygen (6.5 mg/l) corresponded to the optimal values for the life of many fish species, and pH level showed weak water alkalinity. Hydrochemical bay water composition indicated high organic pollution. In both bays, and in the Sviyaga river itself, the content of heavy metals and petroleum products was several times higher than the threshold limit value. BOD5 level in the bays significantly exceeded the limit values. BOD20 and chemical oxygen demand exceeded the standards four times. The results of a microbiological study revealed significant water contamination with Escherichia coli. The species composition of the aquatic phytocenosis in both bays largely corresponded to the Sviyaga River phytocenosis structure. However, the bays are characterized by plant species and ecological processes that indicate the initial stages of their waterlogging.

Public Catering at Logging Sites in the Middle Volga Region during the Pre-War Five-Year Plans

The article examines one of the most important aspects of the industrial and domestic components of the logging process in the 1930s. The work of canteens and food stations for lumberjacks is considered using the example of the Middle Volga region, whose logging was typical for the European part of the USSR. At the same time, the article compares regional problems of catering at logging sites with all-Union trends. The source base for the article was the funds of regional archives of the Penza, Samara and Ulyanovsk regions and materials from periodicals of the 1930s. In general, the catering system at the logging sites of the largest logger in the Middle Volga region, the Sredles trust, was organized already at the end of the first five-year plan. The greatest number of problems in the public catering system in the third five-year plan were recorded in the Kuibyshevles sections. Typical methods for supplying the canteens of timber industry enterprises with products in the 1930s. began to organize their own subsidiary farms and purchase food. There are numerous complaints about the quality of food prepared in the forestry industry canteens. In some cases, the shortcomings of catering at logging sites were associated not with the general food shortage in the USSR, but with the low professionalism of canteen workers.

ФОРМИРОВАНИЕ И СТРУКТУРА ПОРТОВОГО КЛАСТЕРА НИНБО ЧЖОУШАНЬ

The study is devoted to assessing the quality of Russian Federation subjects’ policies in thefield of creative industries. For this purpose, the special methodology and information base were developed, according to which for each region the Index of Creative policies Quality (ICQ) was calculated. The regions were ranked according to the ICQ and the results of the ranking were interpreted. In accordance with the ICQ, characteristics of legal and organizational support, the representation of creative industries in regional socio-economic development strategies, the availability of region-level support and the regions’ participation in the federal support measures, all Russian regions were divided into 4 groups. The top-10 regions included Moscow, St. Petersburg, the Republic of Tatarstan, Novosibirsk, Sverdlovsk, Tomsk, Nizhny Novgorod, Tyumen, Vologda and Ulyanovsk regions. The leading regions are distinguished by the systematic approach to setting strategic priorities in the field of creativeindustries, the diversified organizational infrastructure and initiative in launching regional support measures. There is a connection between urbanization, economic prosperity and the quality of policies in the field of creative industries. The study showed that the policies in the field of creative industries significantly vary by the frequency of occurrence in regions. Thus,the participation in the federal agenda is more common than the developing the region-level measures, and setting goals and objectives aimed at developing creative industries in regional socio-economic development strategies is more common than the creating the specialized strategies.

On the distribution and biology of Elater ferrugineus (Coleoptera: Elateridae) in Russia

Saproxylic beetle communities play an important bioindicator role in the assessment of biodiversity status in forest habitats. These Coleoptera communities also contain a considerable number of threatened species with a low abundance throughout their range. One of these species is Elater ferrugineus (Coleoptera: Elateridae), a threatened species that inhabits old, hollow, deciduous trees. Elater ferrugineus is protected in many European countries, including Russia. In the present study, we provide new data on the distribution of this rare and protected species in Russia. The species has been recorded for the first time in Ulyanovsk Region, Ryazan Region, and Voronezh Region, and it is currently indicated in the fauna of 23 Russian regions. The phenology, habitat preferences, and some other aspects of ecology of Elater ferrugineus in Russia have been characterised. The main period of activity of adult individuals was observed from the third decade of June to the third decade of July. The species is mainly found in various types of deciduous forests (dominated by trees of the genera Quercus, Tilia, Acer, Populus, and Fagus) and in mixed forests. In addition, our research also revealed the presence of Elater ferrugineus in pine (Pinus sylvestris) forest complexes. A general set of measures is proposed to ensure the protection and monitoring of Elater ferrugineus. It is recommended that Elater ferrugineus ferrugineus needs to be included in Red Data Books of all regions where it is known, because at present this species still has no conservation status in several regions of Russia.

ЭФФЕКТИВНОСТЬ И ИНТЕНСИВНОСТЬ ИСПОЛЬЗОВАНИЯ СЕЛЬСКОХОЗЯЙСТВЕННЫХ УГОДИЙ В СУБЪЕКТАХ ПОВОЛЖСКОГО ЭКОНОМИЧЕСКОГО РАЙОНА

The article conducted a study of the efficiency and intensity of use of agricultural land in the constituent entities of the Volga economic region. The Republic of Kalmykia, the Republic of Tatarstan, Astrakhan, Volgograd, Penza, Samara, Saratov and Ulyanovsk regions were analyzed. In the process of studying, the stages of research are considered to ensure stimulation of the goals set for the future. The practical side of effective and intensive turnover of agricultural land and ways to improve it in real use have been worked out. Depending on the ratio of indicators of the capabilities of the Volga economic region, a program of activities has been built for the involvement and expedient exploitation of agricultural land. Inefficient lands and methods of their use through the use of highly effective agrotechnical innovations are considered. Directions for measures to improve consistently ineffective lands are revealed. An important role here is played by targeted actions to improve land through land reclamation. An analysis of the investment climate, key risks and adaptation to modern conditions was carried out. Key positions that hinder the elimination of a number of problems are formulated in the form of a summary consequence. This is associated with the risk of a slowdown in investment attractiveness and competitive advantage, taking into account the global economic context. Despite the significant interest in the use of agricultural land in the subjects of the Volga economic region, the applied interest associated with the possibility and intensity of use to ensure the production of agricultural products is not sufficiently substantiated, the theoretical and practical aspects related to the study of models of economic modernization of this region are not sufficiently developed.

Physico-chemical properties of Russian natural aluminosilicates for purification of aqueous environment

The paper analyses and compares the physico-chemical properties of aluminosilicate green clay and bentonite and diatomite from the Russian deposits. The research determines specific surface area and the morphological features of aluminosilicates, their pore sizes, and pore distribution by volume. The surface of the green clay includes silicon and aluminum oxides, montmorillonite, kaolinite, impurities of pyrite, saponite, micas, and hydrosludes. It also contains a lot of rounded particles with a diameter of 1-2 μm. According to the research, adsorption isotherms for mesoporous green clay samples belong to type IV; the samples of bentonite and diatomite (Middle Volga regions of Russia) belong to type II. They characterize the monolayer-multilayer concentration of solution components on macroporous bodies. Also the research revealed a sufficiently high amount of adsorbate (31 ml • g-1) to cover the surface of diatomite (Ulyanovsk region, Russia) with a monomolecular layer. The source minerals of diatomite are montmorillonite and muscovite. The study of adsorption and desorption branches for a bentonite sample (Samara region, Russia) indicates the processes asymmetry. Hence, we compared the ability to adsorb iron (II) and lead ions from aqueous systems using green clay extracted in different years (2017 and 2023).

РАБОЧИЕ БУДНИ УЛЬЯНОВСКОГО КОЖЕВЕННОГО КОМБИНАТА В 1970-е гг.

The article is based on the materials of the State Archive of the Modern History of the Ulyanovsk region and the State Archive of the Ulyanovsk region, which are introduced to the scientific world for the first time. The authors examine the history and organization of work at one of the light industry enterprises, the Ulyanovsk tannery plant. The main stories are devoted to the analysis of labor discipline, measures of material and moral incentives for workers. The authors pay attention to the scale of staff turnover and measures to reduce it, to suppress non-normative behavior, in particular alcoholism. A conclusion is drawn about the socio-economic importance of the enterprise for the regional economy during the Soviet period. The authors argue that the inherent potential and traditions of maintaining production made it possible to preserve the Ulyanovsk tannery plant in the changed conditions of the 1990s and the continue its activities as the Closed Joint Stock Company "Ulyanovsk Shoe Factory".
