New approach in teaching English language in the globalization era
Статья научная
English language is identified as one of the most spread languages for the worldwide communication. The intensive globalization of the world in the last decades requires international communication within the wider range of nations and cultures. It is important to recognize the continuous shift of the role of the English language from a second language into the global nature of the English language, in the context of worldwide communication, stressing the fact, that English as a foreign language has become international language. Within the concept of English as a language used for international and intercultural communication, it is consequently important to consider the inseparable role of culture in a language as the cause of the shift from the cultural aspect in English as a second language into the intercultural aspects in English as an international language including consideration of its possible impact on teaching English as an international language.

New book format of the XXI century - electronic textbooks
Статья научная
The rapid informatization process of the education system has created both the opportunities and the need for the use of e-books in education. E-books allow students to actively participate in the learning process, to personalize their learning, to gain new knowledge and to evaluate their own abilities. The e-textbook also enriches traditional forms of learning, encompassing a large amount of teaching and learning materials and stimulating the development of new teaching methods. In our opinion, it is time to switch to electronic and interactive formats in the development of electronic aids and textbooks in universities. One of the leading directions in the use of information and communication technologies today is the effective use of computers in educational activities. The main issue in implementing this activity is the selection of e-learning resources that will improve the quality of education.

New mathematical model for the Russian population projections
Статья научная
In this article, a new original mathematical model for the Russian population projections as an autonomous non-Markov queuing system with an unlimited number of servers and two types of customers is built. The research of this system was carried out a virtual phase method and a modified method of asymptotic analysis and was proofed that the asymptotic distribution of applications served in the system at time t is Gaussian. Such a queuing system sufficiently and adequately simulates the process of changing the age structure of the population and can be used to analyze demographic situations in a single country and around the world. The mathematical model has been applied to the analysis of the population growth in Russia. We have built optimistic scenario for population projections to answer the question of how the Russian population will grow without immigration.

New method of using mobile robots for implementing warehouse operations
Статья научная
The new patented method of movements of packaged cargoes at the warehouse is proposed in this article. The proposed method of loading is superior in economic efficiency, reliability, cheapness, simplicity of construction and use, to all other methods of loading implemented by robots. The method allows the mobile robot to load a cargo which is three times as heavy as this mobile robot, wherein almost no electrical energy is consumed during loading. In implementing the method, two mobile robots are used, each of which contains a mobile platform, an omnidirectional mobile wheel-type mechanism and a transport suspension with independent suspension for each wheel. Actually, mobile robots help each other to load cargo on the first mobile robot, through robot cooperation. Loading of the container with the load on the first mobile robot is carried out by actuating a two-arm lever, which is carried out through the impact of the bottom of the mobile platform of the second mobile robot on the longer arm of the two-arm lever by lowering the mobile platform of the second mobile robot due to the operation of the transport suspension of the mobile platform of the second mobile robot. For example, if the length of the longer arm of the two-arm lever is three times longer than the shorter arm of the two-arm lever then the second mobile robot of weight 50 kg is capable of loading a container with a load of weight 150 kg on the first mobile robot.

New method of using mobile robots for moving cargo in warehouse
Статья научная
The new patented method for moving cargo in warehouse is proposed in this article. According to the new method, movement of cargo from the storage area to another warehouse area is carried out by throwing the cargo by the first mobile robot and catching the thrown cargo on fly by the second mobile robot. The parameters of the calculated trajectory of movement, in the free flight phase, of the center of mass of the cargo to be thrown are calculated by numerical methods for solving the Cauchy problem for a system of ordinary differential equations, and by the shooting method for boundary value problems of a system of ordinary differential equations. The first mobile robot throws the cargo at the specified angle to the horizon with the specified initial velocity, at the specified moment of time. In order to catch the thrown cargo on fly by the second mobile robot, the parallel algorithm A1-A2 for catching a thrown cargo on fly by the second mobile robot was created. The method allows the first mobile robot to throw cargoes for large distances, and the created algorithms allow the second mobile robot to catch reliably the thrown cargoes on fly. The proposed method for moving cargo is superior in economic efficiency and reliability to the other methods for moving cargo by implementing tossing of inventory items by robots.

Noceceptive system: features of physiological bases of functioning
Статья обзорная
This article is devoted to the features of the physiological functioning of the nociceptive system. Nociception is a neurophysiological term that describes the totality of the perception, conduct, and processing of signals about processes or effects. Accordingly, the system itself, which implements the translation of such signals, is called nociceptive. The concept of pain reflects a kind of subjective experience accompanying nociception. In addition, there are reactions to nociceptive irritation in the depressed mind. This article reflects the hypotheses that form the concept of a nociceptive system and the physiological mechanisms of perception, analysis and response to nociceptive information. Over the past decade, there has been tremendous progress in the study of the molecular features of phenomena and processes. Multicomponent reactions initiated by the reception of pain, develop according to certain algorithms, referring to the parameters of nociceptive signals, where the study of molecular markers is particularly promising. In the body there is also a specialized response to nociceptive information, which is called the antinociceptive system. The results of many years of research have revealed correlation parallels and significantly significant differences in the neurophysiological and neurochemical mechanisms of pain in a given pathological condition.

Статья обзорная
This literature review focuses on non-alcoholic fatty liver disease (NAFTLD). Today, the world practice of researching diseases is characterized by a multifactor approach, in particular, it concerns pathologies, which are based on a cascade of metabolic disorders, where insulin resistance is one of the key places. Today, NAFTLD is considered an integral part of the metabolic syndrome. The frequency of occurrence of NAFTLD varies from 14 to 26%, in addition, 10% of patients show signs of steatohepatitis non-alcoholic etiology. The pathogenesis of steatosis and metabolic steatohepatitis is poorly studied and there are very contradictory data in the literature, which served as the basis for the creation of this review. The authors consider in detail the historical aspect of the formation of the NAFTLD as an independent nosological unit. A number of etiological aspects of the formation of NAFTLD, but to a large extent, the review is devoted to the mechanisms and pathogenesis of the formation of NAFTLD...

Non-infectious Causes of Rash Mimicking Infectious Diseases
Статья научная
Non-infectious rashes often mimic infectious etiologies and are, therefore, a source of diagnostic difficulty, treatment delays, and mismanagement. The clinical overlap is due to similarities in morphology, systemic symptoms, and patterns of distribution. This article provides an in-depth scholarly review of the non-infectious disorders that clinically resemble infectious dermatologic diseases and includes drug eruptions, autoimmune disorders, allergic reactions, vascular pathologies, genetic syndromes, and environmental causes. Using a narrative review-based methodological approach, clinical presentation, diagnosis-related pitfalls, differential features, and modern investigative techniques are discussed. The findings highlight the need for early consideration of non-infectious mimickers in clinical assessment to avoid unnecessary use of antimicrobials and adverse consequences. Recommendations for practitioners relate to structured diagnostic algorithms, increased dermatology training, collaboration across medical disciplines, and refined clinical guidelines.

Pleural effusion (PE) is an abnormal accumulation of fluid between the visceral and parietal layers of the pleura. PE is a symptom of more than 80 different diseases, thus affecting doctors of various specialties. Chemical pleurodesis is an artificial induction of an aseptic inflammatory process by introducing various chemical agents into the pleural cavity in order to obliterate the pleural cavity. Despite the fact that the history of pleurodesis is more than a century old, there is still a search for the most effective, safe and affordable sclerosant. Develop our own technique of chemical pleurodesis. Evaluation the efficacy and safety of using iodpovidone as a pleurosclerosant. The study was conducted on the basis of the clinic named after I. K. Akhunbaev National Hospital of the Ministry of Health of the Kyrgyz Republic in the department of thoracic surgery. The study included 51 patients with PE of various etiologies, who were treated in the department from September 2019 to February 2023. PE in all cases had a refractory course. All patients underwent drainage of the pleural cavity, after complete expansion of the lung, a chemical pleurodesis procedure was performed with a 10% solution of iodpovidone. After this manipulation, we evaluated the effectiveness and safety of the technique. An effective technique is possibility to reduce the volume of pleural fluid and, as a result, remove drainage from the pleural cavity. In 45 cases out of 51, the technique was effective, which amounted to 88.2%. It is important that the procedure was accompanied by minimal side effects in the form of pain and temperature reaction. Chemical pleurodesis with iodopovidone is an effective, safe and affordable method in the treatment of patients with refractory PE.

The spatial distribution of heavy oils and natural bitumen’s depending on their reserves is analyzed. It is shown that due to the deterioration of the structure of the reserve in the direction of increasing the share of hard-to-recover oils, the role of heavy oils and natural bitumen’s in the overall hydrocarbon balance increases. Analysis of reserves showed that most of their world reserves are concentrated in Canada, Venezuela, and Russia. The results of studies of the distribution patterns of heavy oils and natural bitumen’s can be used in improving methods of field search and in solving other problems of the oil industry.

Non-verbal means of communication in the Turkish language and their corresponding expressions
Статья научная
The article attempts to describe the gestures used by the representatives of Turkish culture and to classify them by comparing them with Russian gestures. While analyzing gestures, the principle of lacunarity, the absence of a phenomenon in a comparable language, was taken into account. The material of the study was the observation of the process of communication of representatives of various cultures with native speakers of the Turkish language, an analysis of literature, from which one could draw descriptions of certain gestures, materials of modern media. The research methodology is based on a comparative analysis of two languages in an asynchronous context. The study of gestures led to the following results: 1) the vast majority of gestures are lacunas (which have no analogs in another culture) for a representative of Russian culture; 2) gestures close in execution have distinctive features that do not allow them to be equated to Russian gestures in full. The possible coincidence of gestures in the aspect of execution, an increase in the number of borrowed gestures from Western cultures, once again proves that it is a nonverbal culture that is a ‘living substance’, influenced by cultural and socio-political changes in society. Nevertheless, in spite of this, today it is possible to establish and describe purely Turkish gestures, which are an integral part of communication with representatives of Turkish culture.

Baffle heat exchanger is widely used in various production activities because of its simple design and strong adaptability, so the structural optimization of baffle heat exchanger is of great significance to engineering practice. COMSOL software was used to simulate the shell-and-tube heat exchanger with baffles. By comparing and analyzing the simulation results, we find that the temperature field and pressure field of baffle plate are distributed evenly; The existence of baffles leads to the transverse flow of air, which increases the heat exchange area. Another advantage of using baffles is that vibration due to fluid flow can be reduced.

Numerical simulation research on cavitation flow of different fuels in diesel engine injectors
Статья научная
With the increasingly stringent requirements of diesel engine fuel consumption and pollutant emission, higher requirements are put forward for the performance of diesel engine fuel injection systems. Cavitation flow in diesel fuel injectors is an extremely important factor affecting spray characteristics. In this study, the occurrence of cavitation in the fuel injector nozzle and its impact on mass flow rate and vapor fraction at the outlet of the fuel injection hole are studied numerically for various fuels such as diesel, gasoline, ethanol and methanol. The results show that the mass flow rate of diesel is the highest and that of gasoline is the lowest. Methanol and gasoline have the highest vapor content, followed by ethanol, and then diesel with the lowest vapor phase. For mass flow, the mass flow is inversely proportional to the viscosity of the fuel, and for cavitation, the amount cavitation is inversely related to the viscosity of the fuel. This agrees with many researchers’ findings.
