To date, there has been an increase in demand for electric energy obtained from clean renewable energy sources. One of them is wind power. Based on this, the development and research of new types of efficient wind turbines that start working at low wind speeds is an urgent issue. Wind turbines operating based on the Magnus effect have proven their effectiveness. However, the authors of this work, for the first time, to eliminate the problem in the form of an electric drive for the promotion of cylindrical blades added a deflector element to the end of the cylinders. Before creating an experimental setup, it is necessary to numerically investigate the aerodynamics around the wind wheel. For this purpose, numerical simulation of wind wheel aerodynamics has been carried out using the highly efficient Ansys Fluent program. A three dimensional geometry has been created in Design Modeler. A mathematical model grid with a grid number of 47329 consisting of tetragonal cells is constructed. The Realizable k-ε is chosen as the turbulence model. A thorough analysis of the velocity vector distribution fields for flow and pressure velocities in the three-dimensional plane around the wind wheel at air flow velocities of 5.10 and 15 m/s is carried out.
On the issue of a new solution of the materials resistance contact problem on compression of elastic cylinders in contact with parallel generators

Published: February 2023

As a result of logarithmic singularity in the plane classical problem of elastically deformable material mechanics, it is proved that the reference formula for determining the convergence of two statically compressed parallel cylinders made of a homogeneous, isotropic, and physically linear material is not applicable. In the special case of elastic interaction of a cylinder with a half-plane, it is established that the convergence becomes equal to infinity. This paradoxical result confirms the nadequacy of Flaman’s model of a simple radial stress state in determining displacements. Based on this model, it is possible to determine only the stresses in parallel contacting cylinders, while the calculation of displacements, in this case, is not possible. Based on apreviously developed and mathematically approximated by the authors flat design scheme of Flaman the algorithm exception of conflicts has been proposed. The algorithm is based on the integral Fredholm equation solution and can be seen as a new fundamental and applied elasticity theory problem, which is of great importance when assessing the contact of refined strength and stiffness of the cylindrical parts of the supporting structures subject to the general and local deformations (cylindrical rollers, gears, pavements with their seal steel rollers, etc.).

This work considers the results of research of mechanical and tribological properties of surface layer of Ti3SiC2coatings after exposure to pulsed-plasma energy flows. Varying of technological parameters of pulsed-plasma treatment is made by changing the distance of pulse exposure. The analysis of the obtained results shows that the pulsed-plasma treatment technology makes it possible to improve the properties of Ti-SiC based coatings by strengthening the deposited compositions by modifying the structure with an increase in the number of МАХ-phases. It is established that the modification of the structural and phase state of the near-surface layers of the carbosilicide coatings leads to a change in their mechanical properties: an increase in the surface microhardness up to 1.8 times, a decrease in the dry friction coefficient by 1.5-2.0 times and an increase in wear resistance by 2.5 times. Based on the XRD analysis, it is established that the improvement of mechanical and tribological properties of Ti3SiC2 detonation coatings as a result of pulsed-plasma treatment is associated with phase transformations in the surface layer, in particular with an increase in the Ti3SiC2 phase content.

Wave processes are intensively studied in various fields of physics: electrodynamics, plasma physics, radiophysics, acoustics, hydrodynamics, etc. Along with the study of electromagnetic and elastic wave processes, the research of patterns of wave propagation of various physical nature in the presence of mutual transformation are of particular relevance. Wave processes in coupled fields reflect the mutual influence of elastic, electromagnetic and thermal fields. The coupling of electromagnetic fields to the deformation field takes place in a medium with piezoelectric, piezomagnetic and magnetostrictive properties. In the paper, based on the matrix method, the propagation of coupled elastic and electromagnetic waves in media with different physical and mechanical properties is studied. The paper proposes a generalization of non-classical contact conditions for studying the effect of thin layers with different physical and mechanical properties on wave processes. A system of differential equations of the 1st order with variable coefficients is constructed, which describe the propagation of electroelastic waves in anisotropic media of a rhombic system of class 222. The conditions for nonrigid contact for a thin layer with piezoelectric properties are derived. The possibility of studying layers with δ-shaped properties (δ is the Dirac function) is proved.

The main task of creating plasma technologies is to improve the operation parameters of its main element - the plasma torch, which is achieved by designing and constructing its main nodes. The paper analyzes the principles of designing a plasma torch and investigates the characteristics of an arc discharge plasma torch. The possibilities of increasing the thermal stability of the anode structure are considered; the speed and trajectory of powder particles are studied; the axial introduction of the powder through the cathode and the thermal stability of the cathode are studied. Using the finite element method, the effect of the anode shape on the service life of the plasma torch is studied by estimating the heat release power under the condition above the melting temperature of copper (anode). The optimal anode geometry for effective cooling of the unit with radial inlet and outlet of the coolant is determined. The influence of the thermal load on the cathode part of the plasma torch is studied, the thermophysical characteristics of the cathode on the operational characteristics of the plasma torch during the thermal load are taken. The dynamics of the particle by axial injection of the powder through the cathode is calculated, and the dynamics of the heating of the powder particle is determined. The output of the carrier gas is stabilized by a swirler and has great dynamics and is located in the high-temperature part of the arc. The trajectory of the movement of a powder particle in the nozzle area is calculated, which corresponds to the average value of the velocity ≈450-500 m/s. It is found that an increase in the cathode diameter from 3 to 5 mm reduces the thermal load by 50%.

The paper presents the results of a study of the photocatalytic activity of films formed by titanium dioxide nanorods doped with silver nanoparticles and reduced graphene oxide. The obtained nanocomposite materials were studied by optical spectroscopy, scanning electron microscopy, X-ray diffractometry, and Raman spectroscopy. The photocatalytic activity of the samples was evaluated by generating a photocurrent when the surface was illuminated by a modulated light source of a xenon lamp. In addition, the photocatalytic activity of the samples was evaluated by the degradation of the methylene blue dye, which is a model. It was found that the introduction of silver nanoparticles and reduced graphene oxide into the pores of films made of titanium dioxide nanorods leads to an increase in the spectral sensitivity of the sample in the region of 400-500 nm. The increased sensitivity of the sample to visible light leads to an increase in photocurrent generation and is 2.3 times higher than that of the original sample. Degradation of the methylene blue dye after 100 minutes of irradiation in the presence of a TiO2/Ag/rGO sample was 19 %. This is 3 times higher than in TiO2 nanorods films and 2.3 times higher than TiO2/Ag films. The results of the conducted studies have shown that the improvement of photocatalytic activity is associated with a decrease in film resistance, an expansion of spectral sensitivity and an increase in the surface area of the nanorods.

Published: February 2023

In this paper, the definition of the temperature distribution field for a rod made of heat-resistant alloy EI48 is introduced. The authors consider for the study a complete rod of circular cross-section of radius R, of limited length L. Studied body is under the influence of a heat flow q from the surface over the entire cross-sectional area of the left end, and heat exchange with the environment occurs on the cross-sectional area of the right end. The rod is thermally insulated along the side surface. The authors consider two cases: the first is the heat flow with intensity q can be set on the area of a small circle with radius r <R, the second is the heat flow can be set on its part, that is, on the area . During the study, the authors showed that during the thermomechanical process, the strength of each section of the load-bearing structural elements is significantly influenced by the temperature distribution field. The influence of high temperature on the morphology of heat-resistant alloys is also shown. This leads to the fact that in some parts of the structural elements the temperature will be acceptable, and in some — critical. As a result, rapid wear of structural elements and loss of their physical qualities occur. Therefore, mathematical modeling of temperature distribution field for a body of various configurations is an urgent problem. The article presents a method for constructing a mathematical model and a corresponding computational algorithm that allows solving a class of problems to determine the regularities of the temperature distribution field in the elements of rod-shaped structures. To do this, the authors used the energy-variation principle in combination with the finite element method.

The article analyzes the main results of the study of the peculiarities of the professional training of future rehabilitation assistants and occupational therapists in classes on modern rehabilitation technologies in the field of health. The development of rehabilitation and information technologies, electronics, radio engineering, robotics and other fields of science and technology contributes to the emergence of the latest diagnostic, treatment and rehabilitation complexes and systems. Mechanotherapy has always been an important component in the rehabilitation of the restoration of the patient's motor functions. Robotic mechanotherapy is a new method of rehabilitation. At the same time, special robotic structures are used for training the functions of the upper and lower limbs with the presence of feedback. When comparing the quality of robotic therapy training with traditional physical therapy classes, one can focus on the following advantages of the first: extended duration of classes, accuracy of cyclic, repeatedly repeated movements; constant uniform training program; the presence of an assessment of the effectiveness of certain physical exercises performed and the possibility of showing it to the patient. Modern robotic complexes, systems and devices significantly increase the effectiveness of diagnostics, treatment and physical rehabilitation measures. At the same time, the lack of educational literature, which would combine information about known types of complexes, device systems, reduces the effectiveness of the educational process and complicates the adaptation of graduates to rehabilitation industrial activities after graduating from higher education institutions. The presence in the training program of the educational component of modern rehabilitation technologies in the field of health makes it possible to deepen the knowledge and practical skills of the students, aimed at the effective implementation of modern technologies in the system of physical rehabilitation and to acquire competencies corresponding to the educational program. The result of the training of future specialists-rehabilitators for professional activities in the field of rehabilitation is familiarization and mastering of modern methods and tools, algorithms of their action, which will enable them to adapt more quickly in the future in the spheres of operation of foreign robotic and computerized tools that are constantly arriving in Ukraine. during physical rehabilitation procedures in medical and rehabilitation institutions.

The article under review outlines the problems of development and assessment of machine translation that can greatly facilitate global communication, despite the imperfect quality of the source text. Most often the results of online tools require post-editing and can only be effectively used by those who already speak the target language to some extent. The need for a competent translation is growing every year. Today, the search for an algorithm to deliver this quality of translation is one of the most important questions in computer science and linguistics, therefore informing the scientific relevance of this work. It is analyzed different approaches to the machine translation systems, their characteristics, efficacy and the quality of their output. Different approaches to the machine translation systems, their characteristics, efficacy and the quality of their output are analyzed in the article. The main problems we see arising from such translations goes from the fact that the systems depend on a large amount of high-quality data sets (i.e., corpora of texts for specific language pairs). The quality of these sets directly influences the quality of the output, which in our case is the quality of the target language text. It can be seen by comparing the average quality of translation between Google’s and Microsoft’s systems. The former one makes less mistakes on average and does not have as many issues in regards to identifying a contextual meaning of a polysemantic lexeme. It is underlined in the article, that this issue can be fixed to a certain extent one of two ways: hiring professional translators and linguists to compile those parallel corpora or create a possibility for every person to contribute to this process even on a small scale. The first approach would be very time and labor consuming, but would ultimately provide us with a higher quality data set, which may lead to further improvements in MT. The second is already being deployed by all three major NMT systems but may lead slower progression due to lack of quality control and oversight. The potential prospect of this research is seen in widening the subject area of texts chosen to reflect the variety of writing styles in use on the Internet right now. Inclusion of texts from confessional, business, and other styles may allow us to highlight more lacunae in the neural network models and to suggest further means of improvement.

The article is dedicated to the method of digital storytelling in teaching the English language to higher education establishments, in particular enhancing students’ speaking ability which is seen as an interaction and social and situation-based activity. The significance of speaking of learners of English as a second (foreign) language is out of doubt whereas it becomes the dominant tool for communication. Therefore, the necessity to teach students to use language as a communicative means rather than to inform them about the language leads educators to implementation of modern teaching methods. Storytelling as a teaching method has been confidently placed within English teachers’ work for the last two decades and recommended as quite effective and handy which assists to reduce students’ psychological barriers to speaking such as anxiety to perform in public and lack of motivation. It is noticed in the article that several constant and traditional story plots (elementary, butterfly effect or groundhog day, Cinderella syndrome, quest, etc.) are well-known and easily recognizable so teachers can use them to create a comfortable learning environment aimed to support learners’ speaking skills and, as such, focused mostly on their development. The fact that storytelling has great potential while digital storytelling integrates the traditional art of oral storytelling with the technology available in the twenty-first-century classroom is highlighted in the article. This facilitates the process of information perception by young people with clip thinking because the visualization attracts their attention and forms interest in one or another topic or discipline in general. Digital storytelling is mentioned as the practice of combining narrative with digital content, including images, sound, and video to create a digital story using online platforms or appropriate software. Digital storytelling might be incorporated in higher education both working offline and during distance or blended learning, either to introduce new material, encourage conversation, and make abstract or conceptual topics easier to understand. Key words: digital storytelling, method, speaking skills, higher education.

Their data were compared with an age- and sex-matched group of subjects who did not receive collars after PCLF during the same period. Pain intensity (using the Visual Analog Scale), Neck Disability Index, and quality of life (using 36-item Short Form Health Survey) of the patients were compared at baseline, 1, 3, 6, and 12 months postoperatively.Results: A total of 36 patients who received cervical collars after surgery and 40 controls were included. At baseline and 1-month follow-up, there were no differences in pain intensity, functional status, and quality of life between the groups. However, at 3 months postoperatively, the quality of life of the subjects with no orthosis was higher than those who received cervical collars (p =0.01). At 6- and 12-month follow-up, there were no differences between the groups in pain intensity, functional status, and quality of life.Conclusions: No difference in the pain intensity and functional status of patients who used cervical collars and controls was shown in our study. Patients who did not wear cervical collars had a higher quality of life during the 3-month postoperative evaluation. Future prospective, well-controlled studies with longer follow-ups are needed to further investigate the effects of cervical orthosis on the clinical outcome of patients after PCLF.

The article reviews the issues related to the mechanical activation of Portland cement in the separate technology of the production of concrete mixtures in the production of concrete and reinforced concrete products. Usually, an essential characteristic of composite building materials based on Portland cement and its varieties used in building processes is their rapid setting of strength. Therefore, scientific researches related to the development of technologies aimed at the intensification of cement hydration processes and the growth of the speed of concrete strength gaining are relevant. The work presents the main technological processes during the production of concrete mixtures using intensive separate technology. The usage of this technology, particularly, makes it possible to significantly increase the reversibility of forms due to a more intense concrete strength gaining on mechanically activated Portland cement, especially during the early stages of hardening. The need to include mineral filler in the form of ground quartz sand during the preparation of the cement-water composition in a high-speed mixer is founded. It was experimentally discovered that the rapid mixing of the cement-water composition in the presence of a C-3 superplasticizer causes a sharp decrease in its effective viscosity, which positively affects the reduction of the water content of concrete mixtures of the required ease of workability. The mechanical activation of Portland cement causes an increase in the amount of chemically bound water in vintage-age cement stone from 13.1% to 17.9%, which means more than 36% compared to the control. It was established that with the same amount of binder, the strength of the concrete on activated Portland cement on the first twenty-four hours of hardening is 1.8...2 times higher compared to the concrete of similar composition, the binder of which was not activated. Over time, the effect of activation on the concrete strength decreases a little, but even at 28 days, the compressive strength of concrete on the activated binder is 25…30% higher compared to the control.

Comparative microanalysis and elemental analysis of the structure of chips of concrete composites of different strength from compressive structures were used. Analysis of the microstructure of concrete chips was performed using a scanning electron microscope from Oxford SU 70 using a CCD detector. Elemental analysis of objects was performed using energy-dispersive X-wave spectroscopy (EDC analysis). The method of energy-dispersive X-wave spectroscopy is used. The character of opening of cracks of concrete samples in the course of their destruction is analyzed. From the data of X-ray and spectral analysis it follows that in a series of samples of strength of 120 MPa in the process of hydration of clinker minerals during hardening of concrete a number of chemically active substances is formed. These are primarily potassium oxide hydrate, calcium silicate hydrate (HSC) and structural gel models such as Janite and Tobermorite. Modification of the concrete composite with a complex of MK and MTK create conditions for the conversion of unstable and soluble calcium hydroxide into a strong crystalline hydrate of calcium silicate. The structure of concrete compacted in this form gives a significant increase in strength. The influence of ultrafine modifiers on the microstructure of cement stone formed during the operation of the structure and the strength of concrete are determined. The results of the scanning electron microscopy analysis show that the phase sizes differ slightly, but are not larger than ≈20 μm. Characteristic destruction of the sample with a strength of 120 MPa occurred in the main cracks, which develop due to the greater number of phases in contrast to the nature of the destruction of the sample with a strength of 50 MPa, which broke mainly on one structure. The complex of modifiers based on microsilica and metakaolin in the concrete mixture creates conditions for the conversion of unstable and soluble calcium hydroxide into a strong crystalline hydrate of calcium silicate. When using cement with a low content of C3S less than ≈50% significantly complicates the production of high-strength concretes, in particular when using silica and metakaolin, because the effectiveness of these additives implies the presence of excess portlandite Ca (OH)2 in the curing system, while systems with low C3S content is characterized by a reduced content of Ca (OH)2.

System of two differential equations, which describe the liquid motion in a drainage pipeline with variable flow rate and the conditions of liquid entry from the surrounding soil through the walls of the pipe in filtration mode, is considered. It consists of a variable mass hydraulics equation and a modified filtration equation. The explored pipeline is laid with a direct slope "i". It is shown that in this case, the second term of modified filtration equation can be neglected without significant error. By introducing new variables, the original system is reduced to a dimensionless form. The solution of this equations system in dimensionless form is presented. In this case the solution of the original equations system depends on the value of three main factors: the resistance factor of the collecting drainage pipeline "ζl"; the generalized parameter "A", which comprehensively takes into account the structural and filtering characteristics of the stream; the geometric slope of pipeline laying "i". The analysis used the concept of an infinitely long drainage pipeline, which is laid with a slope, or, what is the same, an inclined pipeline with an infinite filtering capacity of the side surface walls. It is noted that such pipeline will have the maximum throughput compared to the same pipeline of limited length. Relatively simple and easy-to-use analytical dependencies were obtained on the basis of the conducted analysis. They allow to calculate the nature of the flow rate variations and pressure drop along the length of the drainage pipeline laid with a certain slope. A series of calculations of the explored pipelines main characteristics were carried out according to the proposed formulas at different values of the slope. Corresponding graphic dependencies were constructed for clarity. It is shown that the value of the geometric slope of the pressure drainage pipeline, along with the resistance factor and the generalized parameter, significantly affects the calculated parameters of such pipelines.
