Conflict Resolution Mechanisms in the System of Interactions of Political Pictures of the World
Authors:   Russian Presidential Academy of National Economy and Public Administration  (North-West Institute of Management of RANEPA), Ivanov Denis Yu.
Published: December 2024

Modern political reality is like an unregulated crossroads where even unspoken norms are no longer respected. This situation leads to difficulties in understanding each other by political actors. The rules of the game become dependent on the initial subjective attitudes and political pictures of the world of political decision-makers. The system of interactions of political pictures of the world is increasingly acquiring a conflict character. Under such conditions, the interpretation and forecasting of political events and situations becomes a difficult task. The issue of formation of scientifically based mechanisms for resolving conflict interactions of political pictures of the world becomes topical. The author analyses such models of interactions from the position of the theory of action and the theory of communicative action. The mechanisms of conflict prevention of political pictures of the world are embodied in a variety of interactive actions manifested in the activities of political institutions. The models of such compensatory interactions are strategic, normative and communicative actions of actors of political pictures of the world.
transformación del rol docente en la era de la Inteligencia Artificial: hacia un liderazgo pedagógico estratégico
Authors: Vallejo Alcira
Published: December 2024

El presente artículo examina el impacto de la Inteligencia Artificial (IA) en la educación, considerándola no sólo como una herramienta de apoyo, sino como una tecnología disruptiva que cuestiona los modelos educativos tradicionales. El análisis crítico del rol docente tradicional muestra la transición del modelo transmisor al facilitador, influido por teorías constructivistas y socioconstructivistas, abarcando también la incorporación de nuevas tecnologías. La transformación del rol docente con la adopción de la IA se explora en cuatro dimensiones: como arquitecto del aprendizaje personalizado, mentor de habilidades socioemocionales, curador de contenidos y alfabetizador digital, constituyendo el nuevo rol de liderazgo pedagógico. Se plantea que la IA potencia el rol docente, pero no reemplaza las cualidades humanas esenciales. Mirando hacia el futuro, la IA abre perspectivas prometedoras para crear entornos de aprendizaje más inclusivos y adaptativos, preparando a los estudiantes para los desafíos del siglo XXI.

2025 arrenca amb més preguntes que respostes. El món ja ha votat i ara toca veure quines polítiques ens esperen; quin impacte tindran les noves agendes guanyadores; fins on arribarà la imprevisibilitat de Trump 2.0; i si estem davant d'un Trump factor de canvi o davant d'escarafalls i focs d'artifici polític.

El 2025 es parlarà de treva, però no de pau. L'ofensiva diplomàtica guanyarà terreny a Ucraïna, mentre la caiguda del règim sirià de Bashar al-Assad obre una transició política incerta. Aquests moviments posaran a prova un sistema internacional incapaç de resoldre les causes estructurals dels conflictes.

El món es debat entre la gesticulació dels nous lideratges, els escenaris canviants que estan redibuixant conflictes enquistats, i una rivalitat sinoestatunidenca que pot derivar en una guerra comercial i tecnològica. La por, com a dinàmica que impregna polítiques, tant en el camp migratori com en les relacions internacionals, guanya terreny el 2025.

Authors: GÜÇLÜ Selahattin , ÖZDEMİR Durmuş , SARAOĞLU Hamdi Melih
Published: December 2024

Image recognition is one of the essential branches of computer vision and has significant theoretical and practical importance. This study aims to enhance a deep learning model, DenseNet, by incorporating parallel structures using X-ray images from the MURA (Musculoskeletal Radiographs) dataset. X-ray images of the elbow and finger are analyzed using AlexNet, DenseNet, Parallel DenseNet, and Proposed Parallel DenseNet (PPDN) deep learning models for anomaly detection, and the results are compared. For the elbow, 1534 healthy and 1630 anomaly X-ray images; for the finger, 1965 healthy and 1938 anomaly X-ray images were used to train the deep learning models. As a result of the statistical analysis, the most successful model with the test accuracy value for the elbow part was the suggested PPDN model (78.74%). The next successful model for the elbow part was AlexNet (77.05%). The most successful model for the finger part was again the PPDN model (69.97%), and the next successful model was the Parallel DenseNet model for the finger part (68.94%). In anomaly detection of musculoskeletal elbow and finger X-ray images, the PPDN model is more successful than the classical DenseNet and Alexnet models in terms of test accuracy.
How to perform a transtracheal aspirate in horses for diagnosis of lower respiratory tract disease
Authors: Bishop Rebecca C. , Nobrega Ana D. , Mersich Ina , Wilkins Pamela A.
Published: December 2024

OBJECTIVE

To describe indications for and demonstrate the technique to perform a transtracheal aspirate in horses. Transtracheal aspirate is indicated to collect samples for cytology and bacteriologic culture in cases of suspected pneumonia or other lower respiratory tract disease.

ANIMALS

1 healthy university-owned horse was used for demonstration purposes. Images of clinical case samples from the University of Illinois Veterinary Teaching Hospital are shown.

METHODS

The horse is restrained and sedated with detomidine or xylazine to facilitate restraint and butorphanol to minimize coughing. The ventral neck is clipped and aseptically prepared. The site of planned puncture proximal to the bifurcation of the sternocephalicus is anesthetized with lidocaine. Two to three 30-mL syringes are filled with saline aseptically. A stab incision is made with a No. 15 blade to the depth of the trachea. The trocar is advanced between tracheal rings on midline, the stylet removed, and the aspiration catheter advanced through the trocar to the level of the proximal horizontal trachea. Sterile saline (30 mL) is infused rapidly, and suction is applied to the syringe while slowly withdrawing the catheter until fluid is retrieved. The catheter and trocar are withdrawn and the puncture site covered with antimicrobial ointment or a light bandage.

RESULTS

Samples are collected in a plain tube for bacteriologic culture and EDTA for cytology. The visual appearance of purulent effluent confirms severe pneumonia.

CLINICAL RELEVANCE

Transtracheal aspirate is minimally invasive and simple to perform with available kits. Samples provide valuable information to guide treatment decisions and selection of antimicrobials for horses with suspected lower respiratory tract disease.
Examining ‘Vernacular’ Symbols and Symbolic Power in Times of Crisis
Authors: Bhutia Kikee Doma
Published: December 2024

This article* examines the significance and impact of vernacular symbols with national and ritualistic importance, focusing on their roles in the conflict between Russia and Ukraine, as well as the Tibetan crisis. The study asserts that the effectiveness of these symbols in mobilising public sentiment depends on their ability to elicit a diverse range of emotions. It analyses symbols that have garnered global attention, particularly following Russia’s full-scale invasion of Ukraine on February 24, 2022, and China’s occupation of Tibet in 1959.

The methodology combines fieldwork and interviews with Tibetan communities in Kalimpong near Darjeeling (West Bengal), Belakhuppi (South India), and Sikkim, along with Ukrainians residing in Estonia. By utilising both traditional ethnographic approaches and netnography (Kozinets 2015), the study investigates trends and emotional impacts through social media, incorporating digital tools for interviews.

The research explores the transformation of religious and cultural symbols into instruments for constructing national identity amid geopolitical conflicts. It examines how these symbols validate personal and collective identities during national crises, offering insights into their role in affirming one’s identity as it relates to a lost or threatened nation.
Dramaturgical Tactics in a Chinese Tea Room: Tailoring Self-Presentation for Business Success
Authors: Wang Yanyu , Tian Robert Guang , Walle Alf H.
Published: December 2024

The current paper* studies the strategic behaviour pursued by individuals in Fuzhou City, China, to enhance reputation, power, and social capital through rituals involving drinking Wuyi Rock Tea. The rituals include people consciously acting to improve their reputation by following specific rules when making and drinking the tea in teahouses. The dramaturgical method of social analysis developed by social theorist Erving Goffman draws an analogy between dramatic performance and social actors strategically “playing a part” when interacting with others. Analysing Chinese Wuyi tea rituals using this approach demonstrates the value of the dramaturgical paradigm within strategic sciences such as business anthropology.
Dressing the Part: Producing Ethnic Minority Textiles in the Era of Intangible Cultural Heritage Tourism
Authors: Hertz Carrie
Published: December 2024

Visualizing difference is central to ethnic tourism and intangible cultural heritage (ICH) performance in Southwest China today. The expectation that individuals in ethnic minority communities will always be dressed and ready to meet romanticized expectations, while otherwise living their lives, creates new subjectivities and refashions how people think about and interact with their traditional material practices. ICH interventions may promise support for minority cultural reproduction but can instead disincentivize the intergenerational transmission of skilled knowledge. At the same time, individuals are experimenting with new forms of entrepreneurial heritage-making that meet community needs without official ICH endorsement, including the development of small-scale ethnic fashion industries. Based on fieldwork in Baiku Yao and Sanjiang Dong communities in the Guangxi Zhuang Autonomous Region, this study highlights individuals engaged in the making, wearing, and marketing of minority dress on an expanding national stage.
PHYGITAL APPROACH IN THE PRACTICE OF TEACHING ENGLISH TO STUDENTS OF NON-LINGUISTIC SPECIALTIES AT UNIVERSITY
Authors:   Bunin Yelets State University, Puzatykh A.N.
Published: December 2024

The relevance of the study is explained by the growing demand for effective training in the field of foreign languages, since today it is impossible for a modern university graduate to achieve the required level of professionalism without developed foreign language competence. The process of closer integration of digital technologies into teaching practices comes to the fore. This area is called “phygital learning”. The phygital approach combines physical and digital interaction. The article discusses the application of this approach in teaching English to students of non-linguistic specialties at universities. The purpose of the study was to describe the possibilities and practice of using phygital components, such as working with online platforms, interactive tasks with traditional teaching methods during foreign language classes. The research methodology included an analysis of theoretical works by both domestic and foreign authors, existing pedagogical practices, and an assessment of student performance and engagement. The main attention was paid to such aspects as developing language skills, increasing motivation, and creating an interactive educational environment. The article presents practical examples of the implementation of the phygital approach in the educational process. The results of the study show that the implementation of the phygital approach provides a personalized and interactive learning format, which is especially important for students of non-linguistic specialties, where the level of initial language proficiency can vary significantly; increases student motivation due to involvement in the learning process. At the same time, the use of the phygital approach requires a response to certain challenges, such as the need to train teachers, technical support, and balance between digital and physical elements of training.

The paper analyzes the mechanisms of working memory: forgetting as a consequence of reproduction and learning as a consequence of reproduction. Indicators of working memory have a high prognostic value for learning processes, since it is closely linked to attention, the formation of new motor and sensory skills, and ensures the acquisition of languages, reading processes, and arithmetic operations. According to the literature, working memory largely depends on the maturity of the prefrontal cortex, which, in turn, has a nonlinear maturation route. The mechanism of forgetting as a consequence of reproduction is associated with inhibitory control and is a proactive interference. There is still no agreed solution regarding the learning mechanism. The study used O. M. Razumnikova's technique aimed at testing these mechanisms. The results of preschoolers and schoolchildren were divided into clusters in accordance with the reproduction strategy in three series, in which the same set of visual-spatial stimuli was presented on the computer in different orders. Three strategies were described for preschoolers: good first reproduction and pronounced proactive interference; low level of reproduction in three series without pronounced mechanisms; high first reproduction and the emergence of weak learning. In adolescents, 4 clusters were found, among which there was a cluster in which both proactive interference and learning were expressed. The role of prefrontal cortex maturity and its relationship with working memory in preschoolers and adolescents is discussed.
AESTHETIC EXPERIENCE AND ITS ROLE IN THE PROCESS OF PERSONAL AND PROFESSIONAL SELF-REALIZATION OF STUDENTS: PSYCHOLOGICAL ASPECT
Authors:   Peoples’ Friendship University of Russia named after Patrice Lumumba, Zhelezniak N.E.
Published: December 2024

The article is devoted to aesthetic experience as a necessary component of students' self-realization. Its main goal is to demonstrate the value and suitability of using the aesthetic component in the psychotherapeutic and educational process, including for students majoring in natural sciences. The article provides a general overview of the available results of domestic and foreign studies on the use of art in the correction of students' psychoemotional states. The psychological components of aesthetic experience and the mechanisms of art's influence on improving the effectiveness of educational activities are considered. The toolkit of the aesthetic component in educational and psychocorrectional activities is quite wide and can be used in various situations. A modern specialist must have a wide range of competencies to solve complex problems. This means the need to use a creative approach and search for non-standard solutions, which is also facilitated by interaction with the creative component of art. The most undeveloped and controversial aspects of the use of art are highlighted, such as the lack of standardized and sufficiently tested materials for work, which requires further research. By analyzing the available materials, it was found that aesthetic experience obtained through art has a positive effect on the psychological state of students. Teaching with the use of art helps improve academic performance, increases the level of memorization of information, improving cognitive and social skills, and is also a condition for personal development, self-determination and awareness of students' opportunities to express their individuality. It is shown that the inclusion of an aesthetic component in teaching is a necessary component of students' self-realization.

The article presents data from a study of the ideas of primary and secondary school students about artificial intelligence, its use in the educational process in ensuring the personalization of students' education. In modern conditions of the development of society and the demands of the state, expressed in Federal educational standards, much attention is paid to the individualization of the educational process of schoolchildren. One of the means to ensure this process can be the use of modern information technologies. However, science and practice may face the problem of children and adolescents themselves being unprepared to use artificial intelligence. The purpose of the empirical research was to identify existing ideas about artificial intelligence among students in primary and secondary schools. 336 subjects students of grades 5–11 of educational organizations from the North-West region of the Russian Federation took part in the work. Survey methods were used. The data obtained allow us to formulate a number of conclusions about the existence of basic and secondary school students’ ideas about artificial intelligence and options for its use in human life. These studies can become the basis for providing a personalized approach to psychological and pedagogical support and educational activities of students at different levels of education. The obtained research results pose the need to determine the prospects for further work to ensure the personalization of students’ education through the use of artificial intelligence in the process of educational activities.
DİJİTALİZASYONUN TÜRKİYE’DE BÖLGESEL EKONOMİK YAKINSAMA ÜZERİNDEKİ ETKİSİ
Authors: Duru Bengisu , Kuştepeli Yeşim
Published: December 2024

Yakınsama ve dijitalizasyon, küresel ekonominin iki temel bileşenidir. Yakınsama teorisinin en önemli varsayımı, yoksul ekonomilerin kişi başına düşen gelir düzeylerinin zengin ekonomilere kıyasla daha yüksek oranda arttığıdır. Yoksul ekonomilerin gelir düzeyleri zaman içinde bazı varsayımlar altında zengin ekonomilerin gelir düzeyleri ile aynı düzeye gelmektedir. Dijitalizasyon, bir ekonomide insanların günlük yaşamını, üretimi ve dağıtımı kolaylaştırmak, ekonomik büyümeyi iyileştirmek için bilginin dijitalleştirilmesi süreci olarak tanımlanmaktadır. Bu çalışma, 2012-2020 yıllarında Türkiye’nin Düzey-1 bölgelerinde dijitalizasyonun yakınsama üzerindeki etkisini incelemeyi amaçlamaktadır. Öncelikle istatistiki veriler kullanılarak dijitalizasyon ve yakınsama ile ilgili değişkenlerin bölgesel dağılımları haritalar üzerinde gösterilmiş, daha sonra sigma yakınsaması, mutlak yakınsaklık, koşullu yakınsaklık, birim kök testi yöntemleri kullanılmıştır. Temel Bileşen Analizini (PCA) kullanarak, dijitalizasyon, dijital teknoloji kullanımı, altyapısı ve kullanım yeterliliği olarak üç gruba ayrılmış ve üç endeks (DUI, DFI, SI) hesaplanmıştır. Sonuçlar, 2012-2020 döneminde Türkiye’nin Düzey-1 bölgelerinde dijitalizasyonun, başta İstanbul olmak üzere batı bölgelerde daha çok, doğu bölgelerde (özellikle Kuzeydoğu Anadolu bölgesi) daha az gelişmiş olduğunu, bölgeler arası yakınsama olduğunu ve dijitalizasyonun yakınsamayı olumlu etkilediğini göstermektedir.
KÜRESELLEŞME VE KENTLEŞMENİN ÇEVREYE ETKİSİ: TÜRKİYE ÜZERİNE BİR UYGULAMA
Authors: Özgün Fergül
Published: December 2024

Küreselleşme ve kentleşme, sadece ekonomik değil çevresel sonuçları da olan iki önemli kavramdır. Küreselleşme ülkeleri ekonomik, sosyal ve politik açıdan birbirine yaklaştırarak üretimi ve tüketimi değiştirmektedir. Üretim ve tüketimdeki değişmeler ekonomik büyümeyi doğrudan etkilemekte, dolaylı olarak da çevre üzerinde etkiler yaratmaktadır. Kentleşme ise nüfus yoğunluğunun kentlerde birikmesine sebep olarak doğal kaynakların daha yoğun kullanılmasını sağlamaktadır. Bu çalışmada küreselleşme ve kentleşmenin çevre üzerindeki etkileri Türkiye örneği üzerinden incelenmiştir. Farklı küreselleşme türlerinin çevre üzerindeki etkilerinin aynı olup olmadığının test edilmesi ve politika önerilerinin sağlıklı bir şekilde yapılabilmesi için ekonomik, sosyal ve politik olmak üzere üç farklı küreselleşme türü ele alınmıştır. Küreselleşmeye ek olarak kentleşme oranı ve ekonomik büyüme değişkenleri modele dahil edilmiştir. 1980-2021 dönemine ait veriler kullanılarak ARDL analizi uygulanmıştır. Analiz sonuçlarına göre değişkenler arasında eş bütünleşme ilişkisi bulunmaktadır. Uzun dönemde ekonomik ve sosyal küreselleşme CO2 emisyonlarının artmasına sebep olarak çevre kalitesini düşürmektedir. Politik küreselleşme ise CO2 emisyonlarını azaltarak çevre kalitesini olumlu yönde etkilemektedir. Kentleşmenin CO2 emisyonlarına etkisi kısa dönemde negatif yönlü ve anlamlı iken uzun dönemde pozitif fakat anlamsızdır. Politik küreselleşmeyi artıracak politikalar uygulanarak çevre kalitesinin iyileştirilmesi sağlanabilir. Türkiye çevre konusunda uluslararası iş birliği çabalarını hızlandırmalı, uluslararası çevresel politikalara uyum sürecini destekleyecek adımlar atmalıdır.

Published: December 2024

Background. Anti-signal recognition protein (anti-SRP) myopathy is a rare idiopathic inflammatory myopathy in children. Herein, a 3-year-old patient with severe anti-SRP myopathy showing a rapidly progressive disease course is presented in order to increase the awareness of pediatricians about idiopathic inflammatory myopathies.
Case Presentation. A previously healthy 3-year-old girl presented with progressive symmetrical proximal muscle weakness that caused difficulty in climbing stairs for two months prior to evaluation, and a marked elevation of the serum creatine kinase levels. A skeletal muscle biopsy revealed necrotic and regenerating processes, with mild inflammatory changes. Myositis-specific and associated autoantibodies tested by the immunoblot method were positive for anti-SRP. Pulse corticosteroid, intravenous immunoglobulin, and methotrexate were administered. However, muscle weakness progressed, respiratory distress and dysphagia developed. Rituximab was initiated. While on rituximab treatment, she was able to walk independently and muscle enzymes were within normal range at the 15th month of diagnosis.
Conclusion. Early diagnosis of patients with anti-SRP myositis is important to control inflammation and prevent disease progression and complications. To our knowledge, our patient is the youngest case reported in the literature and was successfully treated with rituximab added to conventional therapy.

Physics-Informed Neural Network Surrogate Model for Small-Sample Mistuned Bladed Disk
Authors: Fan Yu , Fan Jiasen , Li Anlue , Wu Yaguang , Wang Wenjun
Published: December 2024

Mistuning in bladed disk structures disrupts their cyclic symmetry, potentially resulting in high cycle fatigue. The stochastic nature of mistuning greatly increases the computational cost of related studies. To improve computational efficiency, previous research has primarily focused on reduced-order models based on finite element methods, whereas the increasing demand for rapid computation and precise predictions has led to the emergence of data-driven approaches. These methods directly use vibration data from bladed disks, eliminating the need for building complex physical models. The accuracy of these methods is dependent on the size of the data, which, however, are often difficult to obtain. To overcome the challenge of insufficient data, this study introduces a Physics-Informed Neural Network Surrogate Model for Small-Sample Mistuned Bladed Disk (PINN-SMBD). This new method combines neural networks with the knowledge of bladed disk dynamics mainly reflected in the following three features: the integration of the governing equations of a mistuned bladed disk in the network architecture, the selection of the input and output according to the frequency independence of the response, and the data augmentation using the cyclic characteristic of bladed disks. Moreover, a dataset construction strategy is proposed that the use of datasets with high variance of mistuning can speed up model convergence and improve accuracy. Finally, a PINN-SMBD model for a dummy bladed disk is built by using only 30 samples which demonstrates remarkable accuracy.

Published: December 2024

To clarify the optimal matching relationship between the inlet velocity [Formula: see text] and baffle height, based on the improved elastic tube bundle (I-ETB) heat exchanger, the vibration characteristics and comprehensive heat transfer performance (HTP) of I-ETBs inside the heat exchanger under various [Formula: see text] were analyzed numerically. The results show that there is an optimal baffle height coefficient [Formula: see text], which matches the specific [Formula: see text]. When [Formula: see text] is 0.1 m/s, 0.4 m/s, 0.7 m/s, and 1.0 m/s, the corresponding optimal [Formula: see text] is 0.70, 0.82, 0.87, and 0.73, respectively. It is evident that as [Formula: see text] increases, the optimal [Formula: see text] initially increases but subsequently decreases. Note that, in the design of heat exchangers, it is very important to customize the baffle height according to the operating conditions. Through the comprehensive evaluation of different cases, within the calculation range of this paper, it is finally concluded that the heat exchanger configuration of case I ([Formula: see text], [Formula: see text]) can achieve the best comprehensive HTP.

Published: December 2024

Demand for lithium is expected to quadruple by the end of the decade. Without new sources of production, the supply-demand curve is expected to invert. Traditional geological reserves will not be able to meet the anticipated gap, thus unconventional sources of lithium will need to be utilized, setting the stage for fierce competition for perhaps the most critical of mineral resources required for the energy transition. Direct Lithium Extraction refers to the umbrella of technologies being developed to access lithium from unconventional sources. Electrochemical extraction offers significant promise for its selectivity and low operating cost when coupled with renewable energy. This review aims to describe materials and process design considerations for electrochemical extraction of lithium from aqueous sources with a specific emphasis on ζ-V2O5 designed in our research group as an insertion host. We point to specific strategies for improving capacity and selectivity for electrochemical lithium extraction based on materials design across length scales. Strategies range from site-selective modification of insertion hosts to controlled tortuosity of ion diffusion pathways in porous electrode architectures. Electrochemical lithium extraction from unconventional sources stands poised to be a linchpin of a sustainable economy when coupled with cleaning of wastewater, hydrogen generation, and recovery of ancillary critical metals.
The First Decade of Colloidal Lead Halide Perovskite Quantum Dots (in our Laboratory)
Authors: Dirin Dmitry N. , Kovalenko Maksym V.
Published: December 2024

Ten years after the discovery of colloidal lead halide perovskite nanocrystals (LHP NCs), the field has witnessed substantial progress in synthetic methods, understanding of their surface chemistry and unique optical properties, precise control over NC size, shape, and composition. Ligand engineering, particularly with cationic and zwitterionic head groups, massively enhanced NC stability, compatibility with organic solvents, and photoluminescence efficiency. These breakthroughs allowed for the self-assembly of monodisperse NCs into complex long-range ordered superlattices and enabled the exploration of collective optical phenomena, such as superfluorescence. The development of low-cost scalable approaches like microfluidic systems and mechanochemical synthesis paved the way for the commercialization of LHP NCs, particularly for the down-conversion films in blue-backlit LCDs and as thermally-efficient color converters in pixelated displays. This review aims to trace the journey of these advancements, focusing on contributions from Switzerland, and outline future directions in this rapidly evolving field, such as quantum light sources, photocatalysis, etc.

Актуальность темы состоит в изучении селевых процессов, которые являются важной составляющей для своевременной защиты территории, населенных пунктов и обеспечения безопасности жизнедеятельности людей. Целью работы является определение расчетных значений максимальных расходов воды и селей по результатам натурных маршрутных данных, необходимых при проектировании селезащитных мероприятий г. Тырныауз, а также исследования, направленные на выявление опасных участков в бассейне р. Камык-суу, влияющих на формирование селевых потоков. Методы исследования - натурные обследования селевого бассейна р. Камык-суу, расчет максимального расхода воды и селевого потока 1% обеспеченности. Результаты. При проведении натурного обследования выявлены оползневые участки и отвалы грунта, являющиеся очагами зарождения селевых потоков. Сделан вывод, что эти участки образовались в результате подрезки склона для устройства автодороги к вольфрамо-молибденовым рудникам. Были проведены расчеты максимального значения расхода воды дождевого паводка и селевого потока 1% обеспеченности для р. Камык-суу. В работе дается сравнительная характеристика расчетных результатов с ранее определенными данными, взятыми из архивных источников. Также в работе даются рекомендации по проведению необходимых мероприятий по защите инфраструктуры г. Тырныауз и безопасной эксплуатации серпантинной автодороги на правом склоне бассейна р. Камык-суу от негативного воздействия селевых потоков.

The relevance of the topic lies in the study of mudflow processes, which is an important component for the timely protection of the territory, settlements and ensuring the safety of people’s livelihoods. The purpose of scientific work is to determine the calculated values of the maximum water flow and mudflows based on the results of field route data necessary for the design of mudflow protection measures in the city of Tyrnyauz, as well as research aimed at identifying dangerous areas in the river basin Kamyk-suu influencing the formation of mudflows. Research methods - natural surveys of the mudflow basin river of the Kamyk-suu, calculation of the maximum water discharge and mudflow of 1% security. Results. During the field survey, landslide areas and soil dumps were identified, which are the centers of the origin of mudflows. It is concluded that these areas were formed as a result of slope trimming for the construction of a road to tungsten-molybdenum mines. Calculations were made of the maximum value of the water discharge of a rain flood and a mudflow of 1% probability for the river Kamyk-suu. The paper gives a comparative description of the calculated results with previously determined data taken from archival sources. The paper also provides recommendations on the necessary measures to protect the infrastructure of the city of Tyrnyauz and the safe operation of the serpentine road on the right slope of the river basin Kamyk-suu from the negative impact of mudflows.

Актуальность работы связана с изучением нового поискового направления на нефть и газ в Предкавказье – в одном из старейших нефтегазодобывающих регионов мира, а её целью – выявление новых поисковых объектов. В работе на основе анализа литературных источников обосновывается нефтегазоносность магматических и метаморфических пород фундамента платформ. При этом отмечено, что большая часть запасов нефти и газа связана с кислыми кристаллическими породами (гранитоидами), находящимися в зонах новейшей тектонической активизации. Среди интрузивных и магматических пород максимальной пустотностью характеризуются наиболее кислые, которые в наибольшей степени предрасположены к вторичным изменениям. Всё это способствует образованию трещин, каверн и пор. Используя метод аналогий и анализ геолого-геофизической и геохимической информации, обосновываются перспективы нефтегазоносности пород палеозойского складчатого основания, в том числе ряда гранитоидных массивов Скифской плиты Предкавказья. Новейшая тектоническая активность выделенных гранитных интрузий в пределах Ставропольского края установлена на основании личных неотектонических и структурно-геоморфологических исследований.

The relevance of the work is related to the study of a new exploration direction for oil and gas in Ciscaucasia – in one of the oldest oil and gas producing regions in the world, and its goal is identification of new search objects. In work based on the analysis of literary sources substantiates the oil and gas potential of igneous and metamorphic rocks of the basement of young and ancient platforms. At the same time, it was noted that most of the oil and gas reserves are associated with acid crystalline rocks (granitoids) located in the zones of the latest tectonic activation. Using the method of analogies and analysis of geological and geophysical and geochemical information, the prospects for oil and gas potential of rocks are substantiated Paleozoic folded base, including a number of granitoid massifs of the Scythian plate Ciscaucasia. The latest tectonic activity of identified granite intrusions within Stavropol region is established on the basis of personal neotectonic and structural geomorphological research.
