Introduction In the aftermath of the pandemic, the need to protect both individual and collective well-being, especially in young people, has driven the study of mental health problems. Before developing a program that focuses on student community well-being, it is crucial to identify and assess community skills. The primary purpose of this study is to investigate the community skills of PUJ nursing faculty students in Bogotá and their participation in and contribution to wellness programs. Methodology Descriptive observational cross-sectional study with a mixed method of data collection. Results concerning the quantitative phase, the question about the existence or absence of Welfare Programmes, most students (68%) do not know of the existence of these, while 17% believe that there are and 15% say that there are not. In the qualitative phase, it was concluded that the most appropriate way to consolidate a culture focused on wellbeing is to allow academic interests and activities that promote mental health to be aligned through a curriculum with student wellbeing as a cross-cutting theme. Conclusions: It is important to mention how community capacities can respond to current issues if the community is committed to change. In this case, we must mention that both the university and the students must recognize each other as a team and as fundamental parts of the change and implementation of well-being programs.

Authors: Kobak Dmitry , Bessudnov Alexey , Ershov Alexander , Mikhailova Tatiana , Raksha Alexei
Published: November 2023

In this research note, we used excess deaths among young males to estimate the number of Russian fatalities in the Russo-Ukrainian war in 2022--23. We based our calculations on the official mortality statistics, split by age and gender. To separate excess deaths due to war from those due to Covid-19, we relied on the ratio of male to female deaths, and extrapolated the 2015--19 trend to get the baseline value for 2022--23. We found noticeable excess male mortality in all age groups between 15 and 49, with 58,500±2,500 excess male deaths in 2022--23 (20,600±1,400 in 2022 and 37,900±1,500 in 2023). These estimates were obtained after excluding all HIV deaths that showed complex dynamics unrelated to the war. Depending on the modelling assumptions, the estimated number of deaths over the two years varied from about 46,600 to about 64,100, with 58,500 corresponding to our preferred model. Our estimate should be treated as a lower bound on the true number of deaths as the data do not include either the Russian military personnel missing in action and not officially declared dead, or the deaths registered in the Ukrainian territories annexed in 2022.

The question of efficiency of use of metalized pellets for production of consumable electrodes subjected to electroslag remelting process in order to obtain metal pure in phosphorus and impurities of non-ferrous metals is considered. Analytical estimation of the processes occurring during the interaction "pellet - ligature" has been made, which allowed to obtain optimal parameters for the formation of consumable electrode from ligature and metallized pellets. The experimental estimation of temperature interval of pellets preheating 300...500 °C was carried out. The optimum temperature of pellets preheating is determined, which is 400 °C. The obtained prototypes are investigated and it is established that pellet preheating up to 400 °C allows to obtain fusion of pellet surface layers with ligature. The technology of formation of expendable electrodes from metalized pellets by pouring liquid ligature into a special liner with a polystyrene rod pre-installed in it has been developed.

Published: November 2023

The results of studies to obtain thermodynamic constants of condensed and vapor phases of binary systems of magnesium with beryllium are presented in this paper, and liquid-vapor phase transitions at atmospheric pressure and in vacuum are also constructed. Mg - Be alloys of a given composition were prepared as a result of this work. The partial pressures of magnesium over binary alloys with beryllium were determined with the use of the boiling point method (isothermal variant). The partial vapor pressure of beryllium was found by numerical integration of the Gibbs-Duhem equation. The partial pressures of magnesium and beryllium are represented by temperature-concentration dependences. The boundaries of melt and vapor coexistence fields of magnesium-beryllium system at atmospheric pressure and in vacuum of 1.33 kPa are calculated and plotted on the state diagram. It is established that the separation of magnesium-beryllium system alloys does not involve technological difficulties.

In this article given physical properties of liquid slag, their influence on the basic parameters of technological processes in Almalyk mining and metallurgical plant. The physical properties of melts directly affect the main parameters of pyrometallurgical processes, as well as the design and operation features of equipment. The physical properties of melts (F) are functions of the composition of the phase under study (Xij) and external parameters that determine the state of the system. These properties reflect the structure of the melt, i.e., they are structure-sensitive properties. The physical properties of the liquid phase should also be understood as its properties that are not associated with changes in its material composition or chemical properties, or are associated to an insignificant extent.

The possibility of smelting an oxide-dispersed strengthening steel alloy using five different approaches involving the introduction of finely dispersed Y2O3 particles into liquid Fe-13Cr steel alloy under vacuum conditions has been investigated. To achieve the objective, five series of experiments were carried out, each differing in the conditions and process of the experiments. Two series of melting, were performed to evaluate the possibility of mechanical introduction of yttrium oxide into the melt under different conditions of introduction. The subsequent three series, were carried out to study the possibility of oxidation of metallic yttrium in the melt with the formation of yttrium oxide particles. In these experiments such parameters as duration of melt holding time and residual pressure in the furnace chamber were varied. When the obtained ingots were analysed by X-ray fluorescence (XRF), inductively coupled plasma atomic emission spectroscopy (ICP-AES) and energy dispersive X-ray spectroscopy (EDS), it was found that a significant amount of yttrium oxide was not successfully incorporated into the steel volume. A method using oxidation of metallic yttrium in the melt by reduction of added iron oxide was found to be the most promising.

Published: November 2023

The problem to refine high-chromium cast iron melts obtained with the use of a large proportion of scraped metal and scrap is considered herein. Since fluxes containing calcium fluoride are currently considered to be environmentally polluting, it is required to reduce the use of fluorides, or completely replace them. It was shown that a decrease in the melting point of the flux can be achieved with the use of a mixture of calcium and magnesium fluorides or by the introduction of boron oxide into the composition of the fluxes. However, the efficiency of these fluxes, as well as silicocalcium additives and vacuum remelting in the high-chromium cast iron melting when a high proportion of scrap in the charge is used, has not been previously considered. In this regard, the effect of these refining methods on the removal of non-metallic inclusions in high-chromium cast iron of Grade 340Х18HML was experimentally assessed. Thermodynamic calculations were performed for the interaction of magnesium and calcium fluorides with non-metallic oxide inclusions typical of high-chromium cast irons and with oxides used for neutral lining of induction furnaces. It has been shown that fluxes based on boron oxide, magnesium and calcium fluorides and their mixtures effectively remove oxide and sulfide non-metallic inclusions; however, they have a destructive effect on the lining of furnaces, significantly reducing its service life. The addition of silicocalcium reduces the content of sulfides but does not affect the content of non-metallic inclusions in the form of oxides and nitrides. Vacuum remelting effectively reduces the number of nitride inclusions.

Modeling of the solitary waves trajectories in “shallow water” environme
Authors: Turbal Yuriy , Turbal Mariana , Bomba Andrii
Published: November 2023

Solitary waves in the “shallow water” environment are considered and approximate approach to calculation and prediction of trajectories of these waves is proposed. We use an approach which was developed in recent years and was called the T-representations method. This method allows to move away from the exact solutions of the corresponding systems of differential equations and construct the trajectory approximately, in fact estimating only the point of maximum of the wave amplitude and its displacement. An appropriate mathematical simplification makes efficient computer simulations possible. In recent years, software packages have been actively used to monitor and predict a number of dangerous natural phenomena, such as Earth Alerts, Pacific Tsunami Warning System, Wave Monitoring Sites and others. But these systems do not take solitary waves into account. Using our approach, it is possible to refine the parameters of solitary waves in a specific environment, investigate whether such waves exist there at all and create functions taking into account solitary waves in monitoring systems.

Published: November 2023

The article is aimed at the development of modern automatic control systems, which should provide high-performance indicators in the conditions of variable operating modes of industrial equipment due to effective control structures and algorithms. The purpose of the study is to reduce the cost of the basic oxygen furnace steel, which is a consequence of the increase in the share of scrap metal due to the enhanced post-burning of CO to CO2 in the cavity, by optimal controlling the duty mode parameters using model-predictive control. The blowing mode of the basic oxygen furnace was considered as a technological object of control, and the problem of controlling blowing parameters in conditions of non-stationarity of the rate of metal decarburization was analyzed. The use of a model-predictive controller made it possible to improve the quality of control for the oxygen flow circuit by 39% and the maximum dynamic deviation of the CO2 content in the gases was reduced by 16.5% compared to the PID control. The implementation of a software-hardware control system using model-predictive control based on a programmable logic controller is considered.

Published: November 2023

Objetivo: El incremento de demandas asistenciales, en un contexto de crisis generalizada de recursos, hace necesario la utilización de sistemas de gestión diferencial, que garantice la equidad y la calidad en la atención ambulatoria, similares a los sistemas de priorización de demandas en los Servicios de Urgencias. Material y métodos: Se utilizaron las escalas HEADS-ED (Home, Education, Activities/peers, Drugs/alcohol, Suicidality, Emotions/behavior, Discharge resources) y Western Canada Waiting List (WCWL), para evaluar retrospectivamente la demanda de varios centros ambulatorios de salud mental infantil y de la adolescencia de la Comunidad de Castilla y León (España), recogiéndose motivos, tiempos de respuesta y los sistemas de priorización vigentes (normal o preferente). Resultados: Se ha observado que la mediana en el tiempo de espera para una demanda normal es de 60 días (Rango intercuartílico o RIC=40,75-113,25) vs 35,0 días (RIC=21,0-35,0) en la demanda preferente, que disminuye con la entrevista de acogida hasta 21,0 días (RIC=11,0-29,0) vs 5,0 días (RIC=1,0-7,0) respectivamente.. Según el sistema empleado (HEADS-ED ó WCWL modelo Finlandés o Canadiense) en los casos derivados a Salud Mental Infanto-Juvenil no se alcanza el punto de corte entre un 13,2%, 40,7% y un 76,3%, respectivamente. Conclusiones: Los sistemas de priorización (HEADS-ED y WCWL) han detectado demandas injustificadas. Se sugiere la necesidad de establecer sistemas de gestión de la demanda online, sistemas de priorización y ampliación de las modalidades de atención, para que de forma coordinada mejoren los procesos de atención.

Purpose: to analyze the results of experiments on the use of irrigation regimes and methods when cultivating corn in different climatic and soil conditions. Discussion. The overview of research works devoted to the study of irrigation methods and regimes for cultivating corn for grain on various types of soil in a number of regions of the Russian Federation and other countries, including former Soviet republics is presented. It has been determined that irrigating corn increases yields by 2–3 times. The optimal level of soil moisture in the root layer is approximately 70–80 % of the minimum moisture capacity. The most advanced technology of irrigation reclamation when cultivating corn for grain is drip irrigation, which allows soil cultivation be carried out simultaneously with irrigation at the optimal time, preventing soil erosion, and meeting the needs of plants for water and nutrients as accurately as possible. When growing corn on heavy soils, chieseling has a positive effect, which can increase the yield by 24 % compared to the traditional technology of basic tillage, which involves plowing to a depth of 30 cm. Conclusions: in the process of developing an irrigation regime when growing corn for grain, it is necessary to take into account the crop biological features, climatic and soil conditions of the area, the degree of drainage and water supply of the territory.

At the same time, the factors of influence varied in the range: the water level in headwater from minus 8.2 to minus 1.2; water level in tailwater from minus 7.9 to minus 6.7. Materials and methods. The study of a complex system was carried out in two stages. At the first stage, the pore pressure under the underground dam, responsible for the seepage under it, was calculated using the finite element method based on the Midas GTX NX software package, which has the ability to take into account the complex joint operation of the underground dam and the soil mass. At the second stage, the resulting array of numbers, which reflects the physical processes occuring when the response function, which is taken as the pore pressure under the underground dam, is affected by disturbances, for which the water levels in headwater and tailwater of the dam are taken, was subjected to digital analysis. Results. The range of pore pressure values at the maximum headwater levels is 31.72 % over the entire range of tailwater levels. For the average levels of the headwater, the range of pore pressure values is 32.70 %, and for the minimum levels of the headwater, the range of pore pressure values is 39.41 %, also in the entire range of changes at the tailwater levels. Thus, the lower the headwater level, the greater the impact on the pore pressure of the tailwater level. Conclusions: with a change in the studied range of water levels in headwater or tailwater of the dam, i.e. factors of influence, with a decrease in the values of the impact factors, the degree of their influence on the pore pressure under the underground dam decreases, and with growth – increases, and it occurs almost linear.

Purpose: collection, analysis and generalization of data on wind speed and the intensity of deflation processes in Rostov region, that helps assessing the quantitative side of soil loss depending on wind speed, weather conditions, terrain, tillage method and other factors, and development of wind corridors for the conditions of the region under consideration. Materials and methods. The research was carried out on chestnut soils, southern and ordinary chernozems of the agricultural enterprise “Rassvet” of Aksai district and the agricultural enterprise “Krasnoarmeyskoe” of Oryol district of Rostov region, and the results of other scientists, who have been conducting research in Rostov region since 1969, were analyzed and summarized. Wind speed was measured with anemometers at a height of 2 m above the soil level, and the soil mass moved by winds was determined by the Erosion bridge (pin method) and dust collectors of our own design. Methods of analysis and synthesis as a systematic approach to achieving the goal were used. Results. The wind direction and speed in Rostov region depend on the seasonal position of pressure centers: the Siberian maximum in winter and the Azores in summer. Over the 54 years of research from 1969 to 2023, dust storms and drifting snow were observed 11 times, i.e. once every five years. Mathematical processing of long-term research data made it possible to obtain dependencies for assessing the effect of wind speed on soil removal on average in 1 hour, to determine soil removal coefficients, to propose zoning of the region into five deflationary regions, to develop a map diagram of deflationary zones and wind corridors of Rostov region. Conclusions. The greatest soil losses in wind-impact directions were in 1969 up to 800–900 t/ha for a duration of 300 h, in 1972 – 170–200 t/ha for a duration of 96 h; in 1984, with a daytime wind speed of 10–14 m/s with gusts of up to 25–30 m/s for a duration of 142 h, soil losses amounted to 218 t/ha.
