Authors: Bertolissi G. , Chazelas C. , Bolelli G. , Lusvarghi L. , Vardelle M. , Vardelle A.
Published: November 2022

This study examines the fundamental reactions that, in the solution plasma spraying process, lead to the conversion of the precursor salts to solid material that is deposited onto the substrate. The study specifically focused on the phenomena occurring in-flight and the effect of plasma jet treatment on the mechanical and thermal treatment of the solution injected in the form of a liquid jet. The evolution of precursor droplets in the plasma flow was investigated “in situ” using a shadowgraphy technique. The morphology and structure of material deposited onto smooth stainless steel substrates during single scan experiments were characterized by SEM, GI-XRD and micro-Raman spectroscopy and were correlated to the in-flight observations, in order to evaluate the effect of the plasma-forming gas and solution solvent.

Published: November 2022

This study reports on the effect of combined pulsed laser ablation and laser pre-heating surface pre-treatments to cold spraying Ti and Ti-6Al-4V on coatings’ microstructure, bond strength and cohesive strength. The Ti and Ti-6Al- 4V coatings were sprayed on pure titanium and Ti-6Al-4V substrates, respectively. Coatings were characterized by SEM and porosity level was evaluated through image analysis. Bond strength was evaluated by standard ASTM C633 pull tests and by the laser shock (LASAT) technique. Cohesive strength was evaluated by the cross-section scratch test method. Results show that among the spray conditions used in this study, laser pre-treatment yielded high bond strength (such that all cases had higher cohesive strength than the epoxy glue). The LASAT technique provided a means to evaluate the influence of the laser ablation energy density and the laser pre-heating temperature. For both Ti and Ti-6Al-4V coatings, surface pre-heating increased the coating bond strength to the substrate. The laser ablation process would either increase or decrease the bond strength of the coating to the substrate depending on the laser energy density. The laser energy density needs to be adjusted as a function of the surface pre-heating temperature in order to optimize bond strength improvement. Coating cohesion did not improve with continuous laser pre-treatment in-between passes. However, the laser pre-heating helped reduce the coating porosity.
Cryo-Gas Cooling Method and System for Thermal Spray Coatings
Authors: Akuh M. , Mercando L. , Zurecki Z.
Published: November 2022

Thermal spray coating applications require precise control of substrate temperature during deposition in order to achieve optimum performance of the final part. Applications such as high-velocity oxy-fuel (HVOF) hardfacing of aircraft landing gear and plasma spraying of thick sputtering targets are but a few examples where control of substrate temperature throughout the entire coating cycle is critical. A broad effort to develop a versatile and cost-effective cryogenic gas cooling system for controlling part temperature in high-energy thermal spray operations is described. Results show that the new liquid nitrogen cooling technology can significantly improve productivity of many conventional operations and provide corresponding powder and process gas savings by completely eliminating the need for interpass cooling breaks. Optimized temperature control and minimization of coating oxidation during the spraying process, resulting from the use of the new system, were also found to: (1) preserve substrate properties, (2) decrease residual stress gradients at coating interfaces, (3) enable applications of soft masking materials, and (4) increase the deposition efficiency (DE) of WC-CoCr coatings while minimizing decarburization of the WC phase. This work focused on HVOF spraying of WC-CoCr coatings which offer a performance and cost alternative to toxic chromium (Cr6+) plating but yet to be published, recent experimentation with the other coating materials and deposition systems was consistent with the observations reported here.

ANALYSIS OF THROUGHPUT RATE OF HARVESTING AND TRANSPORTATION COMPLEX OF MACHINES FOR SUGAR BEET PRODUCTION
Authors: FRYSHEV S. , VOLOKHA M. , ІKALCHIK M.
Published: November 2022

The article presents a methodology for analyzing the capacity of the harvesting and transport complex (HTC) for sugar beet, which is aimed at finding ways to rationally use the resource of machines in the technological complex. The reloading method of transportation of beet crop is considered, the feature of which is flexibility, adaptability to weather and climatic and economic conditions during harvesting. Under favorable weather conditions and the availability of a sufficient number of motor vehicles (MV), beets, which are taken from the combine harvester from the field by tractor semi-trailer (TS), are reloaded into heavy-duty MV, which are located on the road from the edge of the field, and transported to the sugar factory. In case of changes in conditions (in rainy weather, with overmoistened soil or with insufficient number of vehicles), a loader-cleaner is added to the complex of machines and the work of the complex switches to a transshipment or flow transshipment method. Harvesting and transportation of beets is considered as the work of the technological chain, which consists of three links: "field - beet harvester (BH)", "BH - NP", "NP - ATZ". The main steps of the throughput analysis are determination of the throughput of the first, second and third links, their comparison and subsequent selection and analysis of alternatives that allow to overcome the possible significant difference between their values. The possibility of reducing the throughput of the third link to the maximum possible - the throughput of the first link by reducing by a certain number of vehicles for the transportation of beets with a simultaneous increase in their technical speed. The given example of calculating the number of units of equipment in the harvesting and transport complex in accordance with the developed methodology proves its effectiveness and advantages. The analysis of the throughput capacity of the ZTC shows ways to improve the parameters of the transport process in the technological complex of harvesting and transport operations.
A Deconstructive Analysis of Mohsin Hamidâs Moth Smoke
Authors: Faiz Shamsa , Fatima Iqra , Ajmal Muhammad
Published: November 2022

The aim of the current study is to deconstruct the foremost idea of individuals' struggle in Moth Smoke by Mohsin Hamid. Deconstruction theory states that language is a system of signs (signifier/signified) and, more distinctively, a system of binary oppositions, differences and contradictions. With the application of the Difference, as a tool, the study tries to investigate the non-centricity and free play of signifiers in the novel. The study also identifies the binary oppositions in the novel and destabilizes them by the application of deconstruction theory, given by Jacques Derrida. The result suggests that the deconstructive interpretation of Moth Smoke is rarely definite; instead, it seeks to always problematize the meaning of the text and suggest the depth to which the text operates. The new standpoints regarding man's great effort to survive in society, desire, death, depravity, power, jealousy, redundancy, insatiability, desire, and injustice of our judiciary system are deconstructed.

Protected and Conserved Areas (PCAs) are key ecosystem management tools for conserving biodiversity and sustaining ecosystem services and social co-benefits. As countries converge on a 30% target for protection of land and sea under the post-2020 framework of the United Nations Convention on Biological Diversity, a critical question emerging is, “which 30%?”. One approach to an answer is risk-based: we should protect the 30% that returns the greatest reductions in risks of species extinction and ecosystem collapse. IUCN Red List protocols provide practical methods for assessing these risks. All species, including humans, depend on the integrity of ecosystems for their well-being and survival. Africa is strategically important for ecosystem management due to convergence of high ecosystem diversity, intense pressures and high levels of human dependency on nature. We reviewed the outcomes of a symposium at the inaugural African Protected Areas Congress convened to discuss applications of the IUCN Red List of Ecosystems to the design and management of PCAs. We found significant recent progress in red listing, with c. 1000 ecosystem types assessed across 21 countries. While these span a diversity of environments across the continent, the greatest thematic gaps are in freshwater, marine and subterranean realms and large geographic gaps exist in north Africa and parts of west and east Africa. The projects are implemented by a diverse community of government agencies, NGOs and researchers. Already, they are having impact on policy and management, informing extensions to formal Protected Area networks, supporting decision making for sustainable development and informing ecosystem conservation and threat abatement, both within boundaries of PCAs and in surrounding landscapes and seascapes. We recommend further integration of risk assessments into environmental policy and enhanced investment in ecosystem red listing to fill current gaps.

Published: November 2022

The article is a review of the monograph by S.I. Zakhartsev, D.V. Maslennikov, V.P. Salnikov “Logos of Law: Parmenides - Hegel - Dostoevsky. On the Speculative-logical foundations of the Metaphysics of Law” 2019 and its English edition 2021 In the process of analyzing this work, the peculiarity of its authors’ understanding of the subject and method of philosophy as a science of the universal unity of thinking and being, realized in the complementarity of historical and logical forms, is revealed. Based on this, the authors of the monograph largely fill the gap that exists in philosophical and legal knowledge. Namely: they reveal the theoretical content of the process of mediation of general philosophy and Philosophy of Law. In this context, the philosophical and philosophical-legal teachings of Parmenides, Plato, Aristotle, Descartes, Kant, Fichte, Hegel, Dostoevsky are analyzed as necessary steps in the unified process of cognition of the essence and meaning of legal existence. As a result, the authors of the monograph give a modern interpretation of the main problems of the Philosophy of Law: the problems of the absolute in law, the value dimension in law, the relationship of the historical and logical principles of law and legal thinking, time and eternity, and others, as well as lay the foundations of legal Christology, substantiate the model of the comprehensive theory of law.

Theoretical and legal foundations of the development of federalism in the conditions of centralization of state power in the Russian Federation
Authors: Eriashvili Nodari D.
Published: November 2022

The article analyzes the history of development and some prospects for the future federalism of the Russian Federation, in particular, after the July 1, 2020 the All-Russian vote on amendments to the Constitution of the Russian Federation, according to which a unified system of public power was fixed in the state. In the theory of state and law, taking into account modern world practice, unitarianism may well be combined with the independence of subjects, and federalism with a strong central government. The author of the article explores the issues of the optimal possible combination of unitarianism and federalism. Among the measures needed to be taken in order to modernize (modernize) federal relations, there may be: reforming the state structure through the transition to a model of unitary federalism; unification of the practice of dividing powers and subjects of jurisdiction of the federal center and the subjects of the federation; development of local self-government; increasing the responsibility of state bodies and local self-government for the state of social well-being of the population. Achieving the optimal variant of the federal structure in the Russian Federation implies the need for a preliminary comprehensive analysis of the state of federalism of the Russian Federation, based on the principles formulated in the Constitution of the Russian Federation of December 12, 1993, principles that by their nature corresponded to the interests of the liberal-democratic reorganization of the Russian Federation.

Glucose and Several Mitogenic Agents Modulate the Glucagon-Like Peptide-2 Receptor Expression in Cultured Rat Astrocytes
Authors: Velázquez Esther , Le Baut Ayuso Yannick , Blázquez Enrique , Ruiz-Albusac Juan Miguel
Published: November 2022

Background:

Glucagon-like peptide-2 (GLP-2) is an intestinal trophic factor that induces astrocyte proliferation through its own receptor (GLP-2R), but the control of its expression is not well known.

Objective:

To study the effects of glucose and of different mitogenic agents on the control of GLP-2R expression in cultured rat astrocytes.

Methods:

GLP-2R mRNA content was measured by quantitative RT-PCR.

Results:

GLP-2R expression was higher in proliferating than in resting cells. The expression was dependent of glucose concentration both in the absence and in the presence of GLP-2. In the presence of a high glucose concentration, GLP-2, PDGF, and PDGF plus GLP-2 presented opposite effects depending on the incubation time. However, insulin, IGF-1, and EGF alone, and plus GLP-2 had no effect. IGF-2, but not IGF-2 plus GLP-2, increased the expression. On the contrary, NGF decreased the GLP-2R expression, but NGF plus GLP-2 increased it even until values similar to those obtained with GLP-2 alone. Interestingly, in the presence of a low glucose concentration, leptin and NPY produced a significant reduction of GLP-2R expression.

Conclusion:

Astrocytes are distributed throughout the brain, where GLP-2 appears to have important functions. Since these cells express the GLP-2R, the results of this study could be considered of interest to advance the knowledge of the role of GLP-2 signaling in the CNS, which should lead a better understanding of the events that occur under normal and pathophysiological conditions.

Published: November 2022

Elderly people requiring care the entire day usually depend on the availability of their family members to give assistance. However, the family members might not provide appropriate help especially in an emergent situation. The application of Internet of Things (IoT) technology with a variety of interconnected devices provides the solution. We propose an IoT-based smart healthcare system comprising wearable devices, which integrates a variety of contact sensors with location-based mesh networks (LBMN) such as Wi-Fi and Bluetooth Low Energy (BLE) connections to continuously sense various parameters of aging people. The BLE-connected devices such as wearable sensors, fixed sensors, seat cushions, pedal mats, magnetic reed switches, and mobile devices are all involved in collecting, processing, and transmitting physiological data and their locations to the cloud. Through the utilization of convenient interfaces such as software applications on smartphones and web pages on computers, it provides real time monitoring of the elderly in terms of localization, activity pattern, and health status. Thus the system enables early detection of health risks to the elderly. We used Platform as a service (PaaS) to receive and store the health data generated from the interconnected devices and to perform analysis. The essential feature of this LBMN is to generate a complete 6W(Who, What,When,Where,Why and How)big data for policy, feed it to the PaaS analysis to easily and quickly obtain more accurate data, and then develop possible health strategy or preventive measures. The proposed healthcare system detected that, out of the 20 participants recruited, 2 persons (10%) were often restless. It was also able to detect abnormal daily activity patterns with more tag positioning and the historical data from the devices. More importantly, it can help to prevent potential physical and neuropsychiatric disorders based on the real-time monitoring information and analyzed historical data for the aging people.

Authors: Barua Prabal , Rahman Syed Hafizur , Eslamian Saeid
Published: November 2022

Climate change has become the biggest risk to the nutritional and food security of the planet worldwide. Rising temperatures, uneven rainfall, cyclones and droughts are unfavourably impacting agricultural production, which, in turn, is creating an elevated vulnerability to the livelihood of Bangladesh’s huge population. Bangladesh is an agrarian country and almost half of the population depends on agriculture activities as a profession. But the agriculture sector of the country is experiencing adverse impacts at various levels and ways because of climate change-induced natural hazards. The present study was done to explore the salinity intrusion problem, soil fertility and rice production in the study areas. Besides, the authors also discover some indigenous knowledge-based adaptation and coping practices of the farmers for reducing the impact of climate change in the study areas. The study disclosed that salinity intrusion into the surface water recorded at high values everywhere and the quality of the sediments was alarming. According to the experiences of the farmers, knowledge and resources, they looked for adaptation strategies to cope with the changing climatic situation. The study will help to demonstrate adaptation practices by the farmers for reducing the salinity level of the agriculture field which will be effective in the vulnerable areas of other parts of the country and worldwide while the area was affected by the salinisation problem.

Published: November 2022

Sawa Lake is one unique enclosed water system situated in southwest Iraq. The current study intends to track the change in water level and analyse the reasons and consequences of the shift in the lake’s physicochemical qualities and primary productivity. Monthly samples were taken from three study sites from February to July 2021. The study found that air and water temperatures increased and decreased at all sites, which were evaluated during the study period. The mean salinity values ranged from 85.92 to 19.67‰, with the highest value (52.20‰) occurring before the drought in February and the lowest value (19.67‰) occurring after the drought in July. The pH level ranged from 7.57 to 8.77. The current study’s nutrient concentration (nitrite, nitrate, and phosphate) was 1.04-19.91, 21.51-251.79, 0.26 - 2.37μg/L, respectively, and there was a reverse correlation between nitrite and nitrate with salinity. The productivity measured by the light and dark bottle method recorded the lowest level (0.25 mg/m3/h) before the drought, and the highest level (3.25 mg/m3/h) was observed after the drought period. Chlorophyll concentration decreased during a drought due to lowered nutrient inputs. These data demonstrate that primary productivity in the lake’s waters is relatively low. And, the drought for the lake occurred as a result of a series of reasons that were strongly influenced by human activities. Traditionally, groundwater is extracted for agricultural purposes in this region. Thus, the rate of groundwater flows into the lake decreases, which negatively affects the physical and chemical parameters and thus affects the productivity of the lake. One of the ways of management is to form a national campaign that adopts exceptional measures to meet the challenges related to groundwater by reformulating and developing water systems, in addition to the proposal to reduce the area of the lake basin industrially to one-third, because the water, even if it returns to flood the lake, does not return to the previous quantities. Thus, when the water quality will be good, it will create the appropriate conditions to increase the productivity of the lake.

Authors: Dudoniene Vilma , Balnytė Milda , Kuisma Raija
Published: November 2022

BACKGROUND: Plantar fasciitis (PF) is a common condition amongst athletes as well as in non-sporting population. It is characterised by a sharp pain under the calcaneus during walking. The impact of pain due to PF on gait and static balance is examined in this observational study. OBJECTIVE: To compare gait and balance between individuals with PF and age-matched controls without PF. METHOD: A cross-sectional observational study was executed in an Outpatient Rehabilitation Centre. Twenty-nine participants were included, 14 with PF, and 15 age-matched healthy asymptomatic individuals. Main outcome measures were foot pain, foot function index (FFI), static balance measured with modified Romberg test, static balance measured on the TYMO® system, and gait with the G-Walk System. RESULTS: Foot pain and FFI were adversely related to balance and gait parameters in subjects with PF. Static balance with eyes open and eyes closed on firm and soft surface measured on the TYMO® balance platform as well as gait parameters measured with the G-Walk system, were significantly lower in subjects with PF compared to age-matched healthy controls. CONCLUSION: PF negatively affects parameters of static balance measured with TYMO® system and gait parameters measured with the G-Walk System. However, the Romberg balance test did not detect differences between subjects with PF and age-matched healthy controls.

BACKGROUND: In 2020, a revised version of the International IFOMPT Cervical Framework was published. This framework provides both physical therapists and educators the necessary information to guide the assessment of the cervical spine region for potential vascular pathologies of the neck in advance of planned Orthopaedic Manual Therapy (OMT) interventions. OBJECTIVE: The objective was to develop a framework flowchart which is useful in clinical practice and education to assist physical therapists to improve the safety of OMT, and apply this in a case report. METHODS: The framework was developed in co-creation with manual therapy experts, researchers, educators in manual therapy, patients, medical specialists and the Manual Therapy Association in The Netherlands and Belgium. Manual therapists and patients tested the framework for intelligibility and usefulness. RESULTS: A framework flowchart is developed and presented, that is easy to use in both clinical practice and education. It is a visual representation of the sequence of steps and decisions needed during the process. A case description of a patient with neck pain and headache is added to illustrate the clinical usefulness of the framework flowchart. CONCLUSION: The framework flowchart helps physical therapists in their clinical reasoning to provide safe OMT interventions.

Authors: Liu Zeng-Yao , Xing Zhao-Hui , Wang Wen , Liu Yu-Xi , Wang Rui-Tao , Li Jia-Yu
Published: November 2022

BACKGROUND: Post-hepatectomy liver failure (PHLF) is a severe complication of liver surgery in hepatocellular carcinoma (HCC) patients. Reduced lean body mass (LBM) decreases the immune activity and increases adverse clinical outcomes among cancer patients. OBJECTIVE: We aimed to assess the association between LBM and PHLF in HCC patients. METHODS: PHLF was defined and graded based on the International Study Group of Liver Surgery (ISGLS) criteria. Patients with Grade B or Grade C were included in PHLF ⩾ Grade B group, while others in PHLF < Grade B group. LBM was measured via preoperative computed tomography images. Binary logistic regression was applied for investigating the association between LBM and PHLF. The receiver operating characteristic curve was used to identify potential cut-off values and assess the predictive ability of the measured variables. RESULTS: The PHLF ⩾ Grade B group had significantly lower LBM levels (means ± standard deviation: 57.0 ± 14.1) than PHLF < Grade B group (67.2 ± 15.7) (p< 0.001). After controlling other variables, LBM was an independent protective factor for PHLF ⩾ Grade B (Odds Ratio: 0.406, 95% confidence interval: 0.172–0.957, p= 0.039). The prevalence of PHLF ⩾ Grade B in each quartile of LBM was 29.4% (15/51), 25.5% (13/51), 19.2% (10/52) and 4.0% (2/50), respectively (ptrend< 0.001). CONCLUSIONS: LBM might be a protective factor for PHLF in HCC patients. Our findings might help to develop a novel strategy to reduce the occurrence of hepatic dysfunction following major liver resection. Multicentric prospective studies and further molecular biologic investigation are needed.

Multi-robot path planning has evolved from research to real applications in warehouses and other domains; the knowledge on this topic is reflected in the large amount of related research published in recent years on international journals. The main focus of existing research relates to the generation of efficient routes, relying the collision detection to the local sensory system and creating a solution based on local search methods. This approach implies the robots having a good sensory system and also the computation capabilities to take decisions on the fly. In some controlled environments, such as virtual labs or industrial plants, these restrictions overtake the actual needs as simpler robots are sufficient. Therefore, the multi-robot path planning must solve the collisions beforehand. This study focuses on the generation of efficient collision-free multi-robot path planning solutions for such controlled environments, extending our previous research. The proposal combines the optimization capabilities of the A* algorithm with the search capabilities of co-evolutionary algorithms. The outcome is a set of routes, either from A* or from the co-evolutionary process, that are collision-free; this set is generated in real-time and makes its implementation on edge-computing devices feasible. Although further research is needed to reduce the computational time, the computational experiments performed in this study confirm a good performance of the proposed approach in solving complex cases where well-known alternatives, such as M* or WHCA, fail in finding suitable solutions.
A SWOT analysis of smart governance applications amid the COVID-19 pandemic
Authors: Jiang Huaxiong
Published: November 2022

Smart governance technologies are emergent information and communication technologies (ICT), which amid the COVID-19 pandemic have been widely used to govern COVID’s impacts. However, very few studies have provided insight into the strengths, weaknesses, opportunities, and threats (SWOT) of smart governance technologies under COVID-19. This prevents the widespread usage of smart governance technologies across cities and countries and impedes their usefulness during emergencies. This study combines knowledge of emergency management theory and planning support systems (PSS) to frame the functional usefulness of smart governance technologies in handling practical tasks amid the COVID-19 state of emergency into a task-technology fit model. By employing qualitative content analysis to collect views and insights from the international news-based cases (n= 69), we identify SWOT of smart governance technologies under COVID-19. Results indicate that usefulness of smart governance technologies is reflected in task-handling in the ex-post emergency phases of response (e.g., provide e-health service, tracing and tracking) and recovery (e.g., improve e-government services, enhance collaboration for renewal), whereas few applications focus on tasks in the ex-ante emergency phases of mitigation (e.g., hazard analysis, vulnerability assessment) and preparedness (e.g., planning, training and exercises). Main findings lead to a conclusion that hidden capacities of smart governance technologies can be fully achieved if policy makers and practitioners can focus on the full range of tasks and demands before, amid, or after emergencies and identify collaborative opportunities for technological development.
A novel scheme for determination of vessel heading using airborne magnetic wake scanning
Authors: Monemi Mehdi , Fallah Mohammad Amir
Published: November 2022

Practical remote vessel detection schemes are switching from the active lidar and sonar based methods to modern passive schemes such as analyzing the geomagnetic anomaly initiated from a moving remote vessel. The detection of a remote vessel and its heading direction has been fully studied in our recently published work through analyzing the two-dimensional frequency spectrum image of the magnetic wake captured by an array of magnetic sensors positioned under the sea surface. Instead of employing the fixed-positioned multi-sensor detection scheme, in this work, we study the heading detection of a remote vessel traveling in shallow/deep water through analyzing the measured magnetic anomaly captured by a single airborne magnetic sensor. After representing mathematical expressions of the captured magnetic wake initiated from the remote vessel, we manage to formulate the Fourier transform of the magnetic wake, and show that the detection of a remote vessel as well as its heading direction can be estimated through detecting the frequency corresponding to the peak amplitude of the spectrum. We show through theoretical and numerical results that the lower the cross-angle between the drone and vessel traveling directions, the more accurate the estimation of the heading angle.

Published: November 2022

This paper proposes a multi-objective stratified optimization (MOSO) design for a permanent magnet linear synchronous machine (PMLSM) to obtain higher thrust and suppress the thrust ripple. MOSO can combine the advantages of different optimization methods and have fast and efficient optimization characteristics. Based on the parametric analysis of the influence of the auxiliary tooth size and the end-tooth width on the thrust performance, the sensitive variables are quickly filtered by using the Taguchi method. The response surface model (RSM) is built by adopting the central composite design (CCD) based on the sensitive variables. Moreover, the stratified optimization design of the PMLSM is completed by combining with the multi-objective particle swarm optimization (MOPSO) to achieve a balance between local and global search. Finally, a prototype is manufactured, and experiments are implemented to verify the proposed method.

Published: November 2022

Introduction. The introduction indicates the relevance of the analyzed image of the motherland in modern Buryat prose when shaping the patriotism of schoolchildren and students. Materials and Methods. The study of the formulated problem relies on the methods of cultural-historical and comparative analysis, generalization and synthesis; and the actualization method, which made it possible to comprehend the features of the motherland image created in the prose of modern writers of Buryatia. Results of the research. The image of the motherland in the books by modern Russian-speaking writers of Buryatia consists of several components: the steppe as a nationally marked space, village, family, and others. The most frequent image – the one of the village – given in the village/city, friend/foe opposition, significant for Buryat prose writers, is filled with everyday details and trifles connected with the native home and native people that acquire a symbolic meaning. The blood connection with the homeland helps the heroes overcome the catastrophic nature of time and return to the origins and the spiritual fabric of life. Conclusion. The study of the motherland image in the prose of Buryatia indicates the relevance of this topic in teaching regional literature.
