Microbiota of spring wheat seeds grown within the contrasting agroclimatic conditions of the Tyumen region

Relevance. Pathogenic microbiota of seed grain can cause death of seedlings, root rot, weakening of plants and a decrease in yield. Monitoring of seed grains pathogens infection rate is always relevant because the composition of the microbiota is dynamic due to the influence of natural and anthropogenic factors.Methods. Phytopathological analysis of spring wheat seeds grown at the state variety testing sites of the Tyumen region was carried out in contrasting years: cool and excessively moist in July 2015 and hot with moderate rainfall in 2016. We used the “wet chamber” method. 144 samples were analyzed.Results. Fungus of the genus Alternaria were the most abundant representatives of the grain microbial community. Average infection rate of seed samples with fungi Alternaria spp. was 49.5%. No differences were found by year of the study. In 2015 compared to 2016, higher prevalence of fungus of the genus Fusarium (4.8% vs. 1.6%) and bacteria (5.7% vs. 0.7%) was observed in the seed material. The maximum indicators of Fusarium infestation were observed in samples from Nizhnetavda variety testing site located in the subtaiga zone – up to 30% (variety Ikar). In 2016 compared to 2015, higher infection of seed material with helminthosporiose (7.1% vs. 2.6%) and mold fungi (2.3% vs. 0.2%) was observed. The prevalence of Bipolaris sorokiniana fungi was the highest in wheat samples grown in the northern forest-steppe zone, especially samples from the Yalutorovsky variety testing site — the limit value was 27% (variety SKENT-3). Harmfulness fungus of the genus Alternaria was significantly lower compared to other key representatives of grain microbiota. The average score of seedling damage was 1.4 vs. 2.2–2.6, seed germination indices — 94.1% vs. 53.2–67.4%.

Assessment of Prospects for Sustainable Cross‐Border Cooperation of the Russian Post‐Virgin Regions of the Urals and Siberia with the Republic of Kazakhstan

Aim. Comprehensive assessment of the stability of cross‐border cooperation between the Russian steppe regions of the Urals and Siberia and the Republic of Kazakhstan in the fields of foreign trade and migration. To achieve the goal, a model has been developed to assess the prospects for sustainable cross‐border interaction of the Russian steppe regions of the Urals and Siberia with the Republic of Kazakhstan.The research conducted using the methodology developed made it possible to identify the problems of cross‐border interaction of Russian steppe regions with the Republic of Kazakhstan. Against the background of a decrease in general mobility of the population of the Russian steppe regions, the share of those who left for the Republic of Kazakhstan among the total number of those who left abroad had a positive trend during the period analysed in the vast majority of steppe regions of the Russian Federation. In five of the eight regions considered, the interaction is characterized as "stable" and "steady", "unstable" interaction in the field of migration only in the Altai Territory.The Tyumen Region was the leader in terms of the share in the country's export‐import operations among the steppe regions of the Russian Federation for 2015–2021. In the period under review, foreign trade turnover had a stimulating effect on the economy of the Chelyabinsk region, the Republic of Bashkortostan and the Novosibirsk region. At the same time, the most active foreign trade activity with the Republic of Kazakhstan was observed in the Altai Territory and Omsk and Kurgan regions. Stable cross‐border cooperation in the field of foreign trade with the Republic of Kazakhstan is only in place in the Kurgan region.

Yield, varietal zoning of spring barley in Tyumen region and assessment of ecological plasticity and stability of its varieties

The purpose of the study is to assess the yield of spring barley in the production and state variety testing of the Tyumen region for 2017-2022, its varietal zoning, as well as the yield and adaptability of varieties for 2021-2023 in the conditions of the subtaiga. There was a significant excess of yield in state variety testing compared to production, which averaged 15.0 c/ha in 2017-2022. The originators of most of the varieties approved for use are the Federal Research Centers of the Urals and Western Siberia. The variety Kudesnik (44.8 c/ha) was the best in terms of average yield, and Chelyabinsky 99 (69.2%) – in terms of the realization of its potential. Stress resistance is low in all varieties, which ranged from -31.2 (Orda) to -49.0 (Nord 18/2613). All varieties had significant yield variability, ranging from 42.7% (Orda) to 69.4% (Nord 18/2613). Strong responsiveness to changes in conditions was detected in the varieties KVS Jessy (bi = 1.10) and Nord 18/2613 (bi = 1.34), which are classified as intensive. The varieties Acha, Despina, Kudesnik, Divny and Abba, with a regression coefficient equal to or close to one, were characterized as plastic, and the varieties Orda, Chelyabinsky 99 and Abalak were poorly responsive to changes in conditions (bi < 1). Yield stability is low in all varieties, from St2 = 0.52 (Nord 18/2613) to St2 = 0.82 (Abalak, Orda). The variety Kudesnik (Ei..=4.8) was characterized the greatest indicator of the genotypic effect, and the variety Abalak (143.5%) – the indicator of the yield and stability of the variety. The varieties Abalak (sum of ranks 32) and Kudesnik (sum of ranks 35) were recognized as the best by the sum of the ranks of the indicators of yield and adaptability of spring barley for 2021-2023 in the subtype of the Tyumen region.

Adaptability of hybrid populations of Linum usitatissimum L. in conditions of the Northern Transural region

Relevance. The selection of genotypes with high adaptive properties for the conditions of the Tyumen region allows us to contribute to the development of a regional strategy for breeding and genetic work, selection and cultivation of varieties in connection with changing weather and climatic conditions.Material and methodology. The research was carried out over a three-year period (2020-2022) in the northern forest-steppe zone of the Tyumen region. Intervarietal hybridization (4x4 scheme), evaluation of the obtained material according to morphological (4 pcs.), biological (1 pc.), adaptive indicators (2 pcs.) was carried out using generally accepted methods. The objects of study were 12 combinations of fiber flax, first obtained in the region.Results. Significant differences (p<0.05*) were determined between hybrid populations of fiber flax in the influence of genotype, environment, and genotype-environment interaction on the degree of implementation of the studied traits. Correlation relationships have been identified that determine the fiber content in the stem (r=0.79-0.91*, growing season, plant height, inflorescence length, softness, camber), the number and weight of seeds per plant (r=0.79-0 ,91*, inflorescence length, number, size and crackability of the capsule). Based on the results of individual selection in the third hybrid generation (F3), early ripening (4 pieces), tall (n=4), with the maximum number of bolls (n=4) and the number of seeds in them (n=7), fiber content (n =4) in the stem of the combination.Conclusions. Hybrid combinations of fiber flax with high levels of stable properties (G1, G3, G9, G10, G11), productivity criteria (G1, G2, G4, G7, G8, G9, G11, G12) can be valuable in breeding work.

Качество зерна новых сортов яровой пшеницы в Северном Зауралье

Abstract. The production of high-quality food wheat grains depends to a large extent on the quality potential of the cultivated varieties and the conditions that ensure its implementation. Studies have identified quality-resistant varieties and factors that ensure an optimal combination of yield and grain quality. The purpose of the research is to consider the possibilities of new varieties of spring wheat to form the technological properties of grain in the northern forest-steppe of the Tyumen region. Methods. Studies were carried out in 2021 and 2022 in the northern forest-steppe zone of the Tyumen region at the Ishim state section. The soil is leached chernozem. The predecessor in the experience is pure steam. The technological properties of wheat grain were assessed by the West Siberian Interregional Center for Comprehensive Quality Assessment of the Tested Varieties (Barnaul). The main criteria for assessing wheat varieties are taken as the gluten content in flour, the strength of flour according to the alveograph and the liquefaction of the test according to the farinograph, these indicators in local conditions are often limiting when assessing varieties according to bakery strength. According to the results of studies, it was established that the indicator “gluten content in flour” in the studied varieties significantly depended on meteorological conditions. For example, in 2022, with a higher degree of moisture and a lower degree of heat compared to 2021, in the predominant part of the varieties (80 %), the amount of gluten in the flour was lower than the standards for wheat filler. At the same time, the following varieties showed high opportunities to provide flour with the amount of gluten: Tyumenskaya 25, Agronomicheskaya 5, Baganochka, Dorada, Tyumenskaya 29, Varden. Varieties stood out – their indicators were at the level of requirements for strong wheat: Baganochka, Ishimskaya 12 and Lenta 45. In terms of “dough liquefaction”, a significant part of the varieties corresponded to the class “wheat-filler”. At the level of strong wheat were indicators in the varieties Ishimskaya 12, Zagora Novosibirsk, Nitsa. Scientific novelty: In the conditions of the northern forest-steppe of the Tyumen region, new scientific information has been obtained on the formation by new varieties of spring soft wheat of the state test of technological indicators characterizing the baking power of flour. The highest gluten content in flour of 70% yield was distinguished by the varieties Agronomic 5, Dorada, Varden, Baganochka, Ishimskaya 12, and Lenta varieties were characterized by high indicators of the physical properties of the test on the alveograph; Ishimskaya 12 on the farinograph, Zagora Novosibirsk, Nice.

The object of this study is the economic ecosystem of the territory. The subject of the study is economic relations for the development of the economic ecosystem of the territory on the basis of mapping its elements. The information base of the research was scientific publications indexed in the Scopus and RSCI databases, as well as the author's results on public management of the development of economic ecosystems. The method of logical system analysis is used as a research method. Results. As a result of the conducted research, a scheme of a map of the industry and sphere of activity of the economic ecosystem is proposed, including indicators, participants, products of activity, development trends, assessment experts and conclusions on the development of this sphere of economic activity. An algorithm for mapping the economic ecosystem of the territory has been developed, which includes the stages of segmentation, the formation of maps of industries, the assessment of development projects and the formation of a strategy for the socio-economic development of the territory. Using the example of the development of the Tyumen region, the applicability of mapping segments of the economic ecosystem of the territory for public management of the development of various fields of activity is shown. The novelty of this study lies in the development of the author's approach to mapping segments of the economic eco-system of the territory, which develops the theory of modeling the structure and development of elements of economic ecosystems.

Исследование мотивации будущих врачей к работе в сельской местности и малых городах.

The staffing of state medical organizations with medical personnel is one of the main factors in the implementation of the strategic goals of the state. The relevance of studying the attractiveness of public health care in rural areas and small towns for medical university students is due to the need to take preventive measures to increase the interest of future doctors in working in these areas. Purpose of the study is to develop proposals to increase the interest of future doctors in working in rural areas and small towns. Materials and methods. 529 students of Tyumen Medical University participated in the sociological study. The survey questions are aimed at identifying intentions for the future place of residence, the significance of motivating factors and measures of social support for medical workers in rural areas and small towns that can influence the employment decisions. Results. The priority for 9 out of 10 respondents is career. More than a third of respondents want to live in cities with more than a million inhabitants and about 40% – in the largest city up to 1 million people. Four out of five target students do not plan to continue working in the same locality after fulfilling their obligations to the employer. Findings. The risk of staffing in medical organizations located in some rural areas and small towns of the Tyumen region have been identified. The proposed initiatives can be taken into account by authorities and heads of medical organizations when making management decisions and help improve staffing levels in medical organizations in rural areas, small and medium-sized cities.

The experience of developing, testing and implementing standards of nursing practice in the activities of medical organizations in the Tyumen region is given. The need to update the technologies of simple medical services using evidence-based nursing practice approaches to unify primary accreditation algorithms is substantiated.

Уровни цифрового неравенства: особенности проявления в Уральском федеральном округе

Introduction. Access to information, digital products and services contributes to reducing barriers in individual’s interaction with state, organizations, and other individuals, also providing opportunities for human development. The author assesses the digital inequality level of the constituent entities of the Ural Federal District.Materials and methods. Theoretically, the research is based on the concept of three levels of digital inequality, according to which inequality can be manifested at the level of access to Internet and information and communication technologies; at the level of the users’ digital skills and competencies; at the level of benefits obtained from the use of digital technologies and impacting individual life chances. The materials used are: statistical data of the Russian information society development monitoring, research on the digital literacy of the Russian population, conducted by the Analytical Center of the National Agency for Financial Research, the Russian Association of Electronic Communications, the Ministry of Digital Development, Communications and Mass Communications of the Russian Federation and the National Research University “Higher School of Economics”, as well as the results of an expert survey conducted by the author in 2023 with state civil servants of the Sverdlovsk region and employees of “Electronic government operator”, the state budgetary institution of the Sverdlovsk region.Results. The article reveals the specific features of digital inequality of the entities of the Ural Federal District. The geographical features of the region paradoxically affects the digital inequality level. The more compactly located territories of the Sverdlovsk, Tyumen and Chelyabinsk regions provide for the appropriate infrastructure with better broadband Internet access. A social consequence of low Internet access in the Yamalo-Nenets Autonomous Okrug is, in part, that not all medical organizations can be connected to the Integrated National Health Information System. In addition, there is no direct correlation between Internet access and digital skills development. On the contrary, remoteness and inaccessibility of territories act as drivers for the development of digital competencies of the Khanty-Mansi Autonomous Okrug and Yugra residents, who are more efficient in using digital technologies in e-commerce and public services.Discussions and conclusions. “Bridging the Digital Divide” federal program implementation will increase the information infrastructure availability. Conscious and focused effort is required to improve digital literacy and cyber hygiene of the population.

Germination, survival and preservation of tomatoes when using the technological method of grafting in protected soil

The article discusses the use of technological graftingand its effect on the survival and preservation of tomato plants, and also provides the results of research on seed germination.The purpose of the research is to evaluate the effect of technological inoculation on the survival and preservation of tomato hybrids in protected soil conditions of the Tyumen region. The cultivation of tomatoes at the Narimanovsky municipal plant is carried out using Dutch technology, which has proven its right to be used in the conditions of the sharply continental climate of Siberia and the possibility of creating break-even production based on them. Studies aimed at studying the reception of tomato grafting on stable rootstocks seem timely and promising not only in our country, but also abroad. Scientific research was conducted from 2018 to 2022.The paper presents recommendations for growing tomato hybrids in protected soil as a grafted crop. The advantages of grafted plants are that the graft may not have all types of resistance, and some of them are added at the expense of the rootstock, which is relevant and has not been studied in the conditions of the closed ground of the Tyumen region. Grafting has a complex and prolonged effect on a number of physiological parameters. In the course of research, it was found that growing tomatoes usinggrafting in low-volume hydroponics conditions makes it possible to increase the safety of plants by the end of the turnover.

Relation between complete feeding and blood biochemical indicators in housing of service dogs in a kennel

The purpose of the research was to analyze the relation between the complete feeding and biochemical parameters of blood in service dogs when housing in a kennel in the Tyumen region. The objectives of the research included issues on the assessment and adjustment of the existing diet, the study of the physiological state of dogs and the determination of the economic effi ciency of the proposed diet. The article reveals the problems of non-compliance of the existing diet with the feeding standards for service dogs, especially in terms of vitamin and mineral nutrition. In order to increase the missing indicators such as the content of protein, calcium and phosphorus to the recommended norm, we proposed to include meat and bone meal in the diet in the amount of 15 g, based on 1 kg of live weight of the dog. The ratio of trace elements calcium and phosphorus will be 1.1:1, which corresponds to the norm of 0.8–1.5: 1. The study of the biochemical composition of the blood showed a change in the enzymatic indicators of the serum to the downside, which may be a symptom of vitamin defi ciency in the diet, especially B vitamins (B6, B1). It is necessary to take into account that these indicators increase with physical activity and intensive use of animals. It was found on the based analysis that the cost of a diet with added vitamins and meat and bone meal would be increased by 2 rubles compared to the existing one, but the diet would be balanced in nutrients. When using traditional feed, it is necessary to include balancing additives in the diet, which requires additional costs. At the same time, we can talk about the feasibility of transferring animals from a traditional diet to feeding dry complete feed.

Infl uence of the exercise regime on the quality indicators of sperm production in breeding boars

In the pig breeding industry, the quality of sperm obtained from breeding boars plays an important role in the issue of reproduction. The purpose of the research was to investigate the eff ect of exercise regime on the quality indicators of sperm production in breeding boars. The research was carried out at the Tyumensky Pig Complex LLC in the Tyumen Region. For the research 3 groups of boars were formed with 10 heads in each. The control group did not receive exercise, the 1st experimental group received passive exercise, the 2nd experimental group received active exercise. It was found that the rectilinear motility of sperm, which aff ects the fertilizing ability of semen was in the 1st experimental group of boars 87.0 %, which was by 2.8 abs.% higher than in other groups. Also, more sperm doses were obtained from semen with high rectilinear motility with the same volume and concentration indicators In the groups of boars without exercise and with active exercise, 5.7 % of dead sperm were found, which was by 0.8 abs.% more than in the analogs that received passive exercise (p < 0,05). In the 1st experimental group of boars with passive exercise, the lowest percentage of sperm with defects was found, which aff ects the efficiency of insemination and the quality of the off spring. It was found that passive exercise had a more favorable eff ect on the qualitative indicators of sperm of the breeding boars of the 1st experimental group compared to active exercise (2nd experimental group) and its absence (control group). The use of passive exercise regime for breeding boars had a positive eff ect not only on the quantitative indicators of semen, but also on the quality of sperm and can be recommended at the enterprise when housing breeding boars.

A Large Marine Bird (Aves: Procellariiformes) from the Eocene of Western Siberia.

The article describes the first find of a bird from the Paleogene of Siberia. A fragment of tibiotarsus from the Eocene Tavda Formation of the Tyumen Region (Western Siberia) is assigned to Procellariiformes. The bird is morphologically closer to Procellariidae, but comparable in size to albatrosses (Diomedeidae) and is assumed to represent the stem members of the family. The find indicated for the first time that either stem albatrosses or similar large Procellariiformes could have had a worldwide distribution as early as the Eocene.

Кластерный анализ в оценке эффективности зернового производства Тюменской области

Abstract. In recent years, there has been stable production of grain industry products in volumes that meet the needs of the Tyumen region and allow the sale of products outside the region. The article is devoted to the study of territorial differentiation of the production of grain and leguminous crops in the Tyumen region. The purpose of the study is to assess the efficiency of grain production in the context of municipalities in the south of the Tyumen region and determine the dependence on the level of fertilizer application. Methods. Statistical methods of data processing (analysis of time series, method of variation, method of correlation-regression analysis), as well as cluster analysis using the Ward method, were used for the study. The scientific novelty lies in the fact that municipalities have been clustered and ranked according to a set of parameters characterizing the development of the grain production industry in the Tyumen region. Results. An assessment was made of the scale of industry development for the period from 2018 to 2022, quantitative and qualitative indicators were considered: the size of sown areas, gross yields, yields of grain and leguminous crops differentiated by municipal areas. An assessment was made of the dynamics of development of the grain production industry, trends of changes over 5 years, parameters of the influence and dependence of the yield of grain and leguminous crops on the level of fertilizer application were identified, clusters were identified that reflect the differentiation of municipal areas in grain production.

Chronic kidney disease and chronic heart failure: impact on prognosis and choice of pathogenetic therapy

To evaluate the impact of a decrease in glomerular filtration rate (GFR) on the prognosis of patients with chronic heart failure (CHF), to analyze real clinical practice regarding the frequency of prescribing pathogenetic therapy for CHF, achieving target dosages depending on the gradation of GFR in patients included in the CHF Register of the Tyumen region. The analysis included medical data of 4077 patients (1662 men and 2415 women) with NYHA class I-IV CHF who underwent examination and treatment in medical organizations of the Tyumen region for the period from January 2020 to May 2023. Criteria for inclusion in the register: proven heart failure. Chronic kidney disease (CKD) was assessed by GFR calculated using the CKD-EPI formula (ml/min/1.73 m2). The primary end point was defined as death from all causes. GFR<60 ml/min/1.73 m2 was recorded in 34.6% of patients, more common in women (40.2 and 26.6%, respectively; p<0.001). When dividing patients into phenotypes according to LVEF, no statistically significant differences were found in the distribution of patients according to GFR. In patients with HFrEF and HFpEF GFR<45 ml/min/1.73 m2 was associated with an increased risk of meeting the endpoint. Analysis of prescribed pathogenetic therapy showed that in patients with HFrEF, the frequency of prescription of ACE inhibitors, â-blockers and MRA decreased (p=0.023, 006 and 0.01, respectively), and ARNI, on the contrary, increased with a decrease in GFR (p=0.026). In patients with HFpEF, a similar trend towards a decrease in the frequency of prescription of ACEIs and MCBs with a decrease in GFR (p<0.001) remained, but it was compensated by an inversely proportional increase in the frequency of prescription of ARBs (p<0.001). 100% of the target dosage is achieved in more than 90% of patients taking MRA across the entire LVEF range. While for â-blockers and ARNI/ACE/ARB the percentage of patients receiving the full therapeutic dosage of drugs is significantly lower. When analyzing target dosages of pathogenetic drugs, gradations of achieved doses were distributed evenly throughout the entire range of GFR. GFR<60 ml/min/1.73 m2 occurs in every 3 patients with CHF across the entire range of LVEF. A decrease in GFR worsens the prognosis of patients with both HFrEF and HFpEF, increasing in direct proportion with the severity of the stage of CKD. Inclusion of patients in the monitoring program within the framework of the CHF service allows the treatment to be significantly brought closer to optimal drug therapy, at the same time, certain efforts are required to overcome difficulties with titration to target dosages.

Features of Coronary Atherosclerosis in Patients with Coronary Artery Disease Residing in the Far North

Aim: To evaluate the features of coronary artery disease (CAD) in patients in the Far North and determination of the potential impact of extreme climatic factors on the development of coronary atherosclerosis. Material and Methods. Using the “Register of performed coronary angiography operations”, 5,679 patients with coronary artery disease were selected, who underwent coronary angiography at the Tyumen Cardiology Research Center. The main study group consisted of 2,590 patients permanently residing in the YamaloNenets Autonomous Okrug and 3,089 patients residing in the South of the Tyumen Region. Results. Patients with permanent residence in the Yamalo-Nenets Autonomous Okrug were on average younger (53.20 ± 7.49 versus 56.79 ± 8.34 years, p &lt; 0.001), men were more common among them. In the extreme North there were more smokers (40.7 vs. 32.0%, p &lt; 0.001) and alcohol users (19.7 vs.15.0%, p &lt; 0.001), and more frequent myocardial infarction in anamnesis (57.1 vs. 48.2%, p &lt; 0.001). At the same time, in patients permanently residing in the South of the Tyumen Region, a burdened hereditary history of CAD was more often determined, and the frequency of arterial hypertension and dyslipidemia was higher. In groups balanced by baseline clinical and demographic characteristics, including CAD risk factors, patients from the Yamal-Nenets Autonomous Okrug had more frequent lesions of the three main coronary arteries: anterior descending artery (42 vs. 35%, p &lt; 0.001), circumflex artery (25 vs. 23%, p = 0.038) and right coronary artery (42 vs. 38%, p = 0.007). It should be noted that in balanced groups in patients permanently residing in the Far North, occlusive lesions of the coronary arteries were statistically significantly more likely to be determined (54 vs. 47%, p &lt; 0.001). Also, between the compared groups, statistically significant differences were found in the type of left ventricle (LV) myocardial remodeling, but these differences were not determined in the balanced groups. Also, in the group of patients permanently residing in the Far North, there was a trend towards a decrease in the LV ejection fraction (53.6 ± 8.6% vs. 54.2 ± 8.7, p = 0.074).Conclusion. In patients with verified coronary artery disease living in the Far North, a more frequent and pronounced atherosclerotic lesion of the coronary bed is determined. These pathological changes are probably due to the complex impact of unfavorable natural and climatic environmental factors.

Patterns of peasant way of life in Tobolsk province in the second half of the XIXth century (on the materials of N.N. Mataev’s personal archive)

The goal of the research is to analyze the specifics of the everyday life of old-timer peasants of Tobolsk province on the basis of information collected during ethnographic fieldwork in the Tyumen region. On the basis of the involved narrative sources, such as personal diaries, memoirs, biographies and retelling of ancestral memories of the hereditary peasant N.N. Mataev, marital behavior, child-parent relations, interaction between family members in and out of the home lifehave been studied, the level of child mortality and birth rate have been analyzed, and the cultural specifics of everyday life of several generations of one family have been revealed. The collected records in the form of interviews, diaries and memoirs refer to the end of the 19th century and the beginning of the 20th century, i.e. to the period of active changes and transformations in the way of life of the peasant village in Russia, which determines the relevance of the research, because a thorough study of the identity of the Siberian sub-ethnos allows us to find differences in the consequences of these transformations and understand the history of Western Siberia. The principle of historicism and the civilizational approach applied allow us to observe the stages of development of new forms of family structure and the transformation of peasant life as a result of modernization. The studied ethnographic materials allow to present more fully the picture of peasant everyday life and to draw conclusions about the specific features of the life cycle of the traditional patriarchal peasant family and the community of old residents of Tobolsk province.

ТЕПЛОФИЗИЧЕСКАЯ МОДЕЛЬ И РЕЗУЛЬТАТЫ ЭКСПЕРИМЕНТАЛЬНОГО ИССЛЕДОВАНИЯ ГАЗИФИКАЦИИ ДРЕВЕСНЫХ И РАСТИТЕЛЬНЫХ ОТХОДОВ

The article compares the calculation results using the developed thermophysical composition model for the study of thermal gasification of wood and plant waste – renewable natural energy resources in a gas generator with the reverse combustion process and forced steam-air blast, which allows to achieve minimal formation of a by-product – resin. Based on the thermophysical model, the optimal consumption of solid fuel – wood and plant waste and oxidizer – atmospheric air is determined. The work can be used by technical engineers at enterprises in Russia and abroad for the environmentally friendly disposal of wood and plant waste in autonomous energy technology installations with combustion gas generators to generate thermal and electrical energy for the consumer. In particular, large volumes of wood and plant waste accumulate at wood processing and agricultural enterprises in the Tyumen region, which are an additional cheap source of energy.
