Проблемы территориального планирования городских агломераций (на примере Республики Башкортостан)

The aim of the research is to study the current state of territorial planning of urban agglomerations in Russia. The authors have considered the peculiarities of agglomerations in Russia, their boundaries and constituent elements. On the example of the Republic of Bashkortostan the differences in the allocation of urban agglomerations while using modern scientific methods are shown. The peculiarities of Ufa and South Bashkortostan agglomerations from the standpoint of territorial planning are highlighted. Insufficient quantity and quality of the sought data does not allow us to apply some of the scientifically based methods for identifying urban agglomerations both in Russia as a whole and on the territory of the Republic of Bashkortostan. In particular, due to the lack of information on pendular migration, the use of data from the All-Russian Population Census of 2020 (2021) is possible only in the case of urban agglomerations. (2021) Population census data can be used only in a very general way. The application of the UN Habitat methodology is possible only for international comparisons and is not applicable in the conditions of the Russian reality, taking into account the prevalence of poorly connected and small in terms of population density urban and rural settlements.

Invading the North: Dispersal of Nearctic treehopper Stictocephala bisonia (Hemiptera: Cicadomorpha: Membracidae) in European Russia

In recent years, the problem of distribution and expansion of new territories by invasive species has become global. The publication analyses the current distribution of Nearctic treehopper Stictocephala bisonia in the European part of Russia. It is a North American species which was introduced into Europe over 100 years ago, but only in the last 20-30 years has it been actively spreading in the continent. In the European part of Russia, the Nearctic treehopper has been known since 1992 from the Rostov region and since 1996 from the Krasnodar Krai. At present the species is reliably registered in 26 regions. The major part of observations (185, 82.2%) is made in the period from 2020 to 2022. Currently, the northern border of distribution is the city of Nizhny Novgorod. In the northeast, the range of the species reaches the Republic of Tatarstan, to the east of the Republic of Tatarstan and the Republic of Bashkortostan, the hopper has not yet been observed. Imagoes are observed in the southern regions beginning in the third decade of June. The maximum number of observations falls on the second and third decade of July and August.

The influence of pre-sowing treatment of seeds with molybdenum on the yield of pea grain in the conditions of the Republic of Bashkortostan

Relevance. Molybdenum is an essential micronutrient element necessary for plant growth and development. In addition to the fact that molybdenum is part of hormones and enzymes, in legumes it improves nitrogen fixation and nitrogen nutrition, increases the efficiency of phosphorus-potassium fertilizers, thereby increasing productivity.The purpose of this work is to assess the effect of pre–sowing seed treatment with various doses of molybdenum on the yield of pea grain.The experiments were carried out in 2019–2023 in the conditions of the Cis-Ural steppe of the Republic of Bashkortostan. The material for the study was the pea cultivar Pamyati Popova.Methods. An ammonium molybdate solution at a dose of 10, 25, 40, 55 g of molybdenum per 1 kg of seeds was used for pre-sowing treatment. Phenological observations, determination of the completeness of germination and plant height, analysis of the yield structure were carried out in accordance with the methodology of the state cultivar testing of agricultural crops.Results. It was found that pre-sowing treatment of pea seeds of the cultivar Pamyati Popova with molybdenum at a dose of 40 and 55 g/c compared to the control resulted in a reliable (p ≤ 0.05) increase in field germination, safety of plants for harvesting, the number of nodules on 10 plants and their weight. As a result of processing pea seeds with molybdenum at doses of 25, 40 and 55 g/c, the number of beans per plant increased by 5.7–11.4%, the number of seeds per plant – by 13.2–19.5%, grain yield – by 7.3–10.7% compared with the control. Thus, in our experiments, pre-sowing treatment of seeds with molybdenum at a dose of 25–40 g/c was optimal for increasing the value of pea grain yield.

Uranium content in drinking water limescale and children’s hair in the Republic of Bashkortostan, Russia

ABSTRACT Analysis of limescales, collected from the walls of kitchenware used to boil drinking water, were used as a surrogate for analysis of uranium in drinking water. Geological features of the territory mainly explained the spatial distribution of uranium concentrations in the samples. Furthermore, uranium was analysed in human hair samples from inhabitants of the region. The median concentration of U in drinking water limescale was 5.4 μg/g (range 0.01 to 61.0 μg/g), and in children’s hair was 0.035 μg/g (range 0.001–0.179 μg/g). A significant correlation (R2 = 0.946) was detected between U in drinking water limescale and U concentration in human hair. Concentrations of uranium in limescales and human hair indicated that the current levels of exposure are in the range of values reported worldwide and are not particularly elevated.

Творчество Галима Хисамова: зарождение политического романа в башкирской прозе ХХI века

The famous Bashkir novelist Galim Khisamov, the author of a number of major novels, occupies an important place in the literature of Bashkortostan in the first quarter of the XXI century. His talent was awarded the Salavat Yulaev State Prize, and many of his works have been translated into Russian. His most important difference among modern prose writers is that the author carries in his work the features of the national heroic character of the Bashkir people. The works of G. Khisamov reflect the mentality of the people, their proud spirit of the owner of their land, demonstrate the high level of intelligence and education of his many heroes, who lead their compatriots to a better life, and thus correspond to the accepted definitions of the nationality of literature. In the historical genre, the novel by the writer G. Khisamov “February Blizzard” was written, which is dedicated to the events of a century ago, the theme of the formation of the USSR and the Republic of Bashkortostan. But a novelty in the genre diversity is his political novel “President Rakhimov”, dedicated to the life of a major leader of such a powerful region as Bashkortostan. If the novel “February Blizzard” of 2017 about the formation of the Bashkir Republic can be attributed to the historical and political, then the novel about the first president of the Republic of Bashkortostan “President Rakhimov” can undoubtedly be attributed to the political. An important indicator of the realism of the novel is the appeal to a contemporary living in our time, a political figure. Of course, in the political novel “President Rakhimov” there are features of historical and industrial novels. Describing the activities of Murtaza Rakhimov as president in close-up, the author delves into the historical, socio-political, as well as production aspects of the republic’s governance for the benefit of its population. Undoubtedly, the experience of artistic development of politics as a specific life material in G. Khisamov’s novel is of interest both from the point of view of the formation of national political history and from the point of view of the development of national artistic and political culture and requires extensive literary study.

Eastern Udmurt Sacred Places, Yesterday and Today

Abstract Most Udmurt living in the Bashkortostan Republic and in the Perm’ region of the Russian Federation are followers of a traditional ethnic religion. In their spiritual life, a huge place is occupied by sanctuaries and other places in which their ritual practices take place, such as the worship of deities, spirits and ancestors. We can identify different types of such places in this Udmurt regional group: the sanctuary dedicated to the cult of the clan protector deities, groves dedicated to the god Lud, places dedicated to personal and family cults, sacred places of agrarian sacrifices, territories where funerary and commemorative rituals take place, places dedicated to the propitiation of evil spirits. Depending on their social status, the sanctuaries are regional or general and can be related to a family, clan, village, or multiple villages. In this article, which relies on the authors’ ethnographic fieldwork and published sources, we analyse the present state of the sacred places. We show that the transformation of cultural patterns has led some types of sanctuary to cease functioning, while others have remained as relics and the places of agrarian sacrifices have undergone an active revitalisation.

Risk factors and integrated assessment of health disorders in teachers of rural comprehensive schools

Teaching is an occupation with high stress levels and extremely poor health indicators, which tend to decline as working records become longer. The aim of this study was to investigate risk factors able to cause health issues in teachers of rural comprehensive schools and to determine the significance of clinical and laboratory indices as early indicators. The work uses the results of hygienic, clinical and laboratory studies aimed at assessing health and working conditions of teachers employed at comprehensive schools in rural areas of the Republic of Bashkortostan. Sanitary and hygienic conditions in classrooms of rural comprehensive schools were assessed in conformity with the Guide R 2.2.2006-05. Medical check-ups resulted in 255 various somatic diseases diagnosed in 70 teachers, overall, 3.64 diseases per one examined teacher. Laboratory tests revealed elevated hemoglobin levels in 20.00 % of the examined female teachers and low ones in 8.57 %. Erythrocytosis was established in 64.29 % of the examined teachers. We also established some slight changes in hematocrit levels, which were elevated in 4.29 % and low in 8.57 % of the examined teachers. Accordingly, in case hemoglobin levels were low, erythrocyte indices MCV and МСН went down as well in 30.00–32.86 % of the female teachers. The number of workers with elevated glucose and cholesterol levels went up as their work records grew longer (the correlation coefficients were 0.94÷0.98). Examination of microflora found in the upper airway mucosa revealed clinically significant contamination, which was mostly represented by cocci bacteria, the most significant microorganisms being Staphylococcus epidermidis, Staphylococcus spp and β-hаemolytic streptococci. Our integrated study has shown that working conditions at workplaces of teachers in rural comprehensive schools do not conform to safety standards as per work hardness and work intensity (intellectual, emotional and sensory loads). The study results confirm high importance of diagnostic methods as indicators of health issues in teachers employed at comprehensive schools. Preventive measures aimed at protecting teachers’ health in rural areas should consider peculiarities of pathomorphosis that determines their health status.

Food Supply in Bashkortostan during Great Patriotic War: Failures and Violations

This study examines the disruptions in the operations of state trade enterprises and consumer cooperatives in providing food to the population of Bashkortostan during the Great Patriotic War. The article is based on unpublished documents from the National Archives of the Republic of Bashkortostan, as well as materials from periodicals. It is revealed that the weakening of the state’s control functions led to an increase in embezzlement and theft in trade and public catering enterprises. The combination of reduced trade turnover and the rise in abuses within the supply system resulted in severe food shortages. Supply disruptions affected workers, officials, evacuated populations, children, and medical institutions. Various abuses are discussed, including food ration card counterfeiting, different forms of self-supply, and instances of double provisioning. Attention is given to violations in accounting for population groups and inflated supply norms. It is established that combating abuses in the supply system was complicated by the involvement of enterprise leaders, shop workers, accountants, and representatives of auditing bodies in criminal activities. The conclusion is drawn that despite numerous violations, the supply system only minimally provided essential food items to the population of Bashkortostan with interruptions and not in full.

Novel Genetic Risk Marker for Paranoid Schizophrenia in the Chromosomal Region 9q21.13 in Tatars: A Genome-Wide Association Analysis

Schizophrenia, the most common severe mental illness, leads to a serious decrease in higher functions, mainly to a change in cognitive functions and perception of reality. Both genetic and environmental factors are involved in its pathogenesis; however, its genetic component still needs to be studied. The aim of the study was to identify genetic markers of paranoid schizophrenia in Tatars from the Republic of Bashkortostan. Genome-wide genotyping of DNA samples was carried out on the PsychChip biochip, which included 610,000 single nucleotide polymorphic variants (SNPs). The studied sample consisted of 357 patients with paranoid schizophrenia and 383 healthy individuals of Tatar ethnicity. As a result of the study, the association of the SNP rs12376586 of the MAMDC2 gene located in the region 9q21.13 with the development of paranoid schizophrenia in Tatars living in the Republic of Bashkortostan was established for the first time.

Hereditary urolithiasis at a young age on the example of a clinical case

To study the clinical features and course of urolithiasis in a young female patient, to suggest the cause of the simultaneous sudden formation of kidney stones in the patient and her mother within a year. Main provisions: urolithiasis (KSD) is one of the most common diseases of the urinary tract. The relevance of effective treatment of this problem arises from the steady increase in the number of patients around the world, especially in Russia. According to many researchers, this trend is due to the increase in life expectancy, changes in lifestyle and nutrition, as well as changes in the composition of water and climate conditions. Approximately two thirds of patients, develop the disease at the age from 30 to 60. Characteristic features of urolithiasis are repeated recurrence and a high incidence of complex forms, which complicates the treatment of such patients significantly. Diagnostic algorithm and treatment of urolithiasis are demonstrated in this article on the example of a medical history of a young patient with rapidly progressing urolithiasis. A similar disease with the same symptoms of urolithiasis was revealed in the patient’s parent a week later, which suggests a hereditary predisposition factor or manifestation of urolithiasis being dependent on the hard drinking water. The simultaneous sudden formation of kidney stones within a year in a patient at a young age and her mother emphasizes the hereditary nature of the disease. Probably, the peculiarities of national cuisine or the individual preferences of patients played a significant role in the development of the pathology. The composition of drinking water is extremely important. The patient is from the Republic of Bashkortostan, where water hardness is 7.8–8.0, which does not meet the standard.

Genome-Wide Analysis of the Risk Association for the Development of Paranoid Schizophrenia in Russians: Search for Genetic Markers in the 1q43 Chromosomal Region

Schizophrenia is a highly hereditary disorder. Genetic risk is associated with a large number of alleles, including common alleles with little effect that can be found in genome-wide association studies. The aim of this study was to study genetic risk factors for the development of schizophrenia in a genome-wide association analysis (GWAS) in Russians from the Republic of Bashkortostan. The studied sample consisted of 320 patients with paranoid schizophrenia and 402 healthy individuals. GWAS genotyping of DNA samples was carried out on the PsychChip biochip, which included 610,000 single nucleotide polymorphic variants (SNPs).

Method of Data Preprocessing on the Basis of Pulse Neural Network to Improve the Accuracy of Water Level Forecast on the Example of Ufa City of the Republic of Bashkortostan

The developed method of data preprocessing based on impulse neural network is considered. The essence of this method is to improve the quality of the initial dataset by minimising data noise. The peculiarity is to improve the accuracy of the predicted values of the time series of water levels obtained at the output of the pulse neural network. Retrospective data were obtained from hydrological posts (river gauge) and automatic stations with the help of FSUE «Centre of Register and Cadastre» from 01.01.1997 to 30.06.2023. On the example of hydrological post 76289 (Ufa) the experiment on forecasting of water levels with the help of the developed system «Flood 2.0» was carried out. The experiment proves the efficiency of the data preprocessing method developed in this study to improve the accuracy of water level forecasts.

Beef productivity of steers of Bestuzhev breed when using an enzyme additive with including of microelements

The value of animals feeding should be provided them with nutrients, but also with biologically active substances such as microelements. Making the task of increasing the productivity of cattle, along with improving the genetic potential, the problem of insuffi cient or unbalanced feeding becomes of great importance. This problem can be solved by using biologically active additives. The purpose of the research was to study the beef productivity of Bestuzhev breed steers with using an enzyme additive containing microelements. The experimental part of the research was carried out at the breeding farm “Agrofi rm Pravda” in the Sterlibashevsky district of the Republic of Bashkortostan. For the experiment steers of the Bestuzhev breed were selected on the principle of analogous pairs and formed into three groups (control, 1st and 2nd experimental). In the 1st experimental group, 15 mg/kg of complete feed enzyme additive plus microelements (protoisotilin with proteolytic activity at a dose of 0,03 % of the dry matter of the ration) was added to the basic ration of steers. In the 2nd experimental group the enzyme amylosubtilin with amylolytic activity was used at a dose of 0,03 % of the dry matter of the ration and a mixture of microelement salts (potassium, cobalt, manganese and citric acid). It was found as a result that with the use of biostimulants for 45 days with 15-day breaks, there was an increase in the total live weight of steers and adipose tissue with a stable carcass weight, regardless of animal groups. The highest rates of slaughter yield were observed in steers of the 2nd experimental group 65,29 %, in steers of the 1st experimental group it was 64,16 % and slightly lower than the control group 63,10 %. The diff erence in comparison with herdmates in the control group was 2,19 and 1,06 %, respectively.

Comparative estimation of grain productivity and green mass of leguminous crops in the southern forest-steppe of the Republic of Bashkortostan

Leguminous crops play an important role in providing the population with high-protein products and farm animals with feed. The correct selection and distribution of species and varieties of these crops in accordance with soil and climatic conditions have a significant impact on their productivity. The purpose of the current work was to estimate productivity of green mass, hay, grain, as well as the degree of development of traits that affect the productivity formation of peas, chickpeas, lentils, spring vetch, and fodder beans when grown in the southern forest-steppe of the Republic of Bashkortostan. The study was carried out in 2021–2023. Contrasting weather conditions made it possible to comprehensively estimate the material being studied. The objects of the study were the varieties of five types of leguminous crops ‘Pamyati Popova’ (peas), ‘Sokol’ (chickpeas), ‘Nevesta’ (lentils), ‘Uzunovskaya 8’ (spring vetch), ‘Kalor’ (fodder beans). The trials were carried out in accordance with the Methodology of State Variety Testing (2019). As a result of the research, there were identified leguminous crops that were the most adaptive in a number of parameters for cultivation in the Southern Urals of the Republic of Bashkortostan, namely peas, chickpeas, lentils with 65.7 ± 9.7–70.7 ± 9.4 days of a vegetation period; peas with a maximum growth rate before the budding phase; peas, chickpeas, spring vetch, fodder beans with the most developed root system; peas and spring vetch with the largest number (223.3±13.3 – 236.0±17.1 pieces, respectively) and weight (0.39±0.04 – 0.45±0.07 g, respectively) of nodules per 10 plants. The maximum productivity of green mass (7.41–7.47 t/ha) and hay (1.87–1.89 t/ha) was obtained from peas and spring vetch. The maximum productivity of seeds (1.48–1.51 t/ha) was from peas and chickpeas. Thus, there has been recommended to expand pea crops, including chickpeas and lentils in the crop rotation, and restoring spring vetch crops. To achieve consistently high yields of these leguminous crops, it is necessary to sow them in the early stages with seeds of higher reproductions, treated before sowing with appropriate disinfectants and microfertilizers.

Рост и развитие бычков лимузинской породы различных генотипов в постнатальном онтогенезе

The purpose of research is to study the growth and development of Limousin bulls of various genotypes in postnatal ontogenesis. Objectives: to study of weight growth, absolute, average daily gains in live weight and relative growth rate of young animals by age periods and for the entire period of growing and fattening; to study of the linear growth of bulls in postnatal ontogenesis based on the dynamics of body measurements and body composition indices. The objects of the study are bulls of the Limousin breed of various genotypes obtained from the mating of cows of French, Australian and local selection with bulls of local reproduction. The scientific and economic experiment was carried out in 2021–2022 at LLC Meat Union of Bashkir Producers, located in the Kuyurgazinsky District of the Republic of Bashkortostan. Indicators of live weight dynamics, live weight gain, relative growth rate, body measurements and body composition indices in the age aspect were studied. Research of the weight growth of young animals of various genotypes made it possible to identify significant differences in terms of absolute and average daily gain in live weight for the entire period of growing and fattening between bulls of the 1st and 2nd experimental groups, respectively, by 32.5 kg and 59.7 g (in both cases – by 6.2 %). The highest values of measurements, indicating the formation of meat qualities and body shape, were noted in bulls of the 1st group compared with peers of the 2nd and 3rd experimental groups. Breeding animals for a long period under different housing and feeding technologies influences the characteristics of the growth and development of the descendants of local reproduction of Limousin breed cattle.

АНАЛИЗ ДЕЯТЕЛЬНОСТИ ВРАЧЕЙ-ДЕРМАТОВЕНЕРОЛОГОВ, ОКАЗЫВАЮЩИХ МЕДИЦИНСКУЮ ПОМОЩЬ СЕЛЬСКОМУ НАСЕЛЕНИЮ В РЕСПУБЛИКЕ БАШКОРТОСТАН

Relevance. Currently, there is a low staffing of medical organizations with local doctors and medical specialists, including dermatovenerologists. This determines the low availability of primary medical care for the rural population for diseases of the skin and subcutaneous tissue. Purpose of the study. To analyze the activities of dermatovenerologists in providing primary specialized medical care to the rural population for diseases of the skin and subcutaneous tissue in the Republic of Bashkortostan. Materials and methods. The calculation of indicators characterizing the activities of dermatovenerologists in the Republic of Bashkortostan for 2017-2021 was carried out: the provision of the population with dermatovenereologists, staffing of regular positions of dermatovenereologists, staffing with individuals, part-time ratio, share of visits per one rural resident and one patient with skin diseases, number of visits in connection with the disease, in connection with the preventive purpose. Results. Level of supply of dermatovenerologists in the Republic of Bashkortostan in 2021. amounted to 0.54 per 10 thousand population. In recent years, the provision of dermatovenerologists in the rural population remains low: in 11.1% of rural areas there are no dermatovenerologists, and in 31.5% the level of provision is insufficient. For the period 2017-2021 a decrease in the number of visits to a dermatovenerologist for skin diseases was established by 16.3% (per rural resident from 0.29 to 0.24 visits per resident), as well as a decrease in the number of visits to a dermatovenerologist by 22.0% . (from 4.63 to 3.61 visits per patient). An extremely low volume of telemedicine consultations was revealed, which is a significant factor in reducing the availability of medical care for the rural population. Conclusions. In the Republic of Bashkortostan in recent years, the provision of dermatovenerologists for the rural population remains insufficient. Thus, there is a need to develop measures aimed at improving primary specialized medical care provided by dermatovenerologists to the rural population of the Republic of Bashkortostan.

Dynamics of Timely Vaccination Among Tender-Age Infants in two Subjects of Russian Federation with the Lowest Immunization Coverage in 2020: Serial Cross-Sectional Study

Background. It was revealed in 2020 that immunization of children in decreed times in several subjects of Russian Federation was below the standard level. Therefore, monitoring of timely vaccination in children of these regions was relevant. Objective. The aim of the study is to evaluate changes in the timeliness of vaccination in children of two subjects of Russian Federation with low immunization rates according to 2020 data. Methods. Immunization of children born in 2015–2017 and 2020–2022 were studied according to the form of federal statistical monitoring (FFSM) No. 6 and vaccination record cards (form No. 063/y) obtained from children's polyclinics of the Republic of Bashkortostan (two in 2020 and three in 2023) and the Republic of Sakha (Yakutia) (two in 2020 and four in 2023). The vaccination timeliness among children against infections from the national immunization schedule (NIS) list was determined. The timeliness of vaccination was evaluated by the proportion of children who received the required number of vaccine doses against each of the infection from the NIS list by the decreed age among all persons of the decreed age. Results. Data from 998 records was analyzed. The increase in timely vaccination against all vaccine-controlled infections in children was revealed. The proportion of children vaccinated according to the NIS has increased by 1.5–4 times. Timely vaccination of 95% children in the decreed age (by FFSM No. 6) was achieved in the Republic of Sakha (Yakutia) against tuberculosis, hepatitis B, measles, rubella, and mumps, and in the Republic of Bashkortostan against measles, rubella, and mumps. The increase in the multivalent vaccines’ usage and simultaneous administration of several vaccines has been discovered. Conclusion. Monitoring the level of documented immunization and timely vaccination in children allows effectively control routine immunization quality. Implementation of multivalent vaccines and simultaneous administration of several vaccines in routine immunization provides radical change in the vaccination rate in pediatric population.
