Authors: Kuznetsova V. N. , Romanenko R. V. 
Published: May 2024

Introduction. Transport and technological means based on tracked undercarriages have found their use in both military and civilian industries. Their widespread use is due to a number of advantages that contribute to the further development of mechanization of production, increasing the efficiency of transportation of minerals, and developing infrastructure during the development of new territories. Ensuring cross-country ability and mobility of vehicles with tracked undercarriages, including tracked conveyor-tractors, is possible through the use of hybrid electromechanical transmissions. One of the components of scientific research in this direction is carrying out simulation modeling of the movement of equipment. Modeling the motion process will make it possible to substantiate the energy characteristics of the electromechanical transmission of a tracked vehicle and confirm the adequacy of previously performed theoretical studies.Research methods. The main objective of the simulation was to confirm the effectiveness of the theoretical studies performed. The studies in the VISSIM programming environment using typical motion cycles that equivalently reflect the operating conditions and use of a tracked machine were carried out.Results. As a result of the research, quantitative estimates of the influence of the power of a diesel generator and the charge of an energy storage device on the dynamic performance of equipment were obtained. It has been established that in order to meet the requirements for promising samples, the power of the energy storage device should be at least 2.5 kWh when using a standard internal combustion engine.Discussion and conclusion. The research results can be used to create, based on the existing scientific and technical background, a promising robotic complex with an electromechanical transmission.
Vibrating roller with compacted soil interaction modelling
Authors: Tyuremnov I. S. , Shorohov D. A. 
Published: May 2024

Introduction. Vibrating rollers are the most common means of compacting soils in construction. The nature of stress development on the contact surface of the roller with the ground depends on the technical characteristics of the vibrating roller (the mass of the roller, the mass of the roller frame, the frequency and driving force of vibrations, the number and characteristics of the roller shock absorbers) and the properties of the soil.Materials and methods. Simulation of the interaction of a vibrating roller with compacted soil was carried out using a three-mass rheological model of the frame-roller-soil system. Differential equations of mass motion in contact and separation modes were solved numerically. To determine the numerical values of the loading time (increase in contact stresses from zero to the maximum value) and the unloading time (decrease in contact stresses from the maximum value to zero), as well as the maximum reaction force of the soil, a computational experiment was conducted on a rheological model. The mass of the vibrating roller module (the mass of the front axle) and the relative driving force were used as independent parameters of the vibrating roller. The coefficients of elastic and viscous resistance of the soil were chosen as independent parameters of the soil. The total number of combinations of factors was 192. The values of the time of loading and unloading of the soil, as well as the maximum strength of the soil reaction, were determined by oscillograms of changes in the strength of the soil reaction over time.Results. Using the STATISTICA program, regression equations, to calculate the numerical values of the loading and unloading time of the soil, as well as the maximum reaction force of the soil and the corresponding values of the reliability coefficients of the multiple approximation, were obtained.Discussion and conclusion. The rheological model reproduces the asymmetric nature of changes in contact stresses during soil compaction by a vibrating roller, observed in experimental stress oscillograms obtained during field experimental studies. The results obtained are important for calculating the depth of stress propagation in the ground and the distribution of stresses in the ground after the passage of a vibrating roller using a wave approach to describing stress propagation in the ground. In the future, it is advisable to conduct a computational experiment with an expanded list of independent parameters of the roller, including the oscillation frequency.

Triggers of Exceptional Experiences on the Camino de Santiago Pilgrimage
Authors: Brumec Snežana 
Published: May 2024

Abstract
This study delves into triggers and transformative effects of exceptional experiences among Camino de Santiago pilgrims. Analyzing 32 travelogues, we identify triggers like exposure to natural beauty and visits to sacred sites, leading to emotional shifts characterized by heightened unity and love. These experiences influence moral and cognitive frameworks, fostering heightened spirituality, wisdom, and detachment. “Experience of deep calm and reconciliation” improves relationships, “Experience of interconnectedness” enhances intuition in decision-making, and “Cathartic experiences” encourage vulnerability expression, fostering connection. Supported by a survey of 501 pilgrims, our findings highlight the frequency and transformative impact of these experiences on a diverse pilgrim population.

Human wildlife conflicts are one of the major challenges for wildlife conservation throughout the globe, and electric fencing (EF) has been used as one of the means to address those challenges. However, the comprehensive study to assess its effectiveness is lacking in many parts. Thus, this study attempted to understand the impact on crops and crop guarding time before and after fencing in communities having both fenced and unfenced households in three Chiwogs under Pemagatshel district. The data were collected through total enumeration using semi-structured interviews from 80 households. Wilcoxon’s signed-rank test showed that the electric fence (EF) has a significant difference (p=0.00, M=50) to farmers in reducing their common crop loss to wildlife and protected staple crop damages (maize). However, bitter buckwheat and radish continued attacking by barking deer. EF reduced both day and night guarding time significantly to all common crops. On the contrary, the unfenced farmers have suffered from increasing pressure from the wildlife after the establishment of EF in their community. Maize and potato damage have significantly increased after EF. There was a significant difference in maize and potato's day and night guarding time before and after EF. Only night guarding time has a significant difference between sweet buckwheat and bitter buckwheat before EF and after EF. Therefore, it emphasizes the need to cover the whole community by EF promoting crop production and reducing crop guarding against wildlife to avert similar issues in other communities.

Authors: Adhikari Pankaj 
Published: May 2024

The understanding of historical floodplain change plays a pivotal role in the minimization of flood risk to communities. Though many research works in Nepal have attempted to study the Land Use Land Cover (LULC) change in different parts of the country, they have not dealt with identification of the floodplain and its change pattern over the period of the time. This study is aimed at understanding the historical change in floodplain of Tinau River in Butwal city which has repeatedly witnessed devastating flooding events. For the purpose, historical Landsat images for the year 1988, 1999, 2009 and 2020 were acquired from earth explorer site of USGS. The supervised classification was performed in QGIS by classifying into vegetation, agricultural land, water bodies, floodplain and settlement. The result shows that there is significant decrease in the area of the floodplain. In the span of around 32 years, its area has decreased by around 229 hectares. The major regions of floodplain encroachment are found to be Buddhanagar, Majuwa and Sundarnagar. Moreover, significant increase in the area of settlement and decrease in agricultural land was observed. The result could be helpful for the policy makers to formulate strategies to prevent floodplain encroachment and cope with flood risk. Likewise, it can be baseline for further studies which delve into the details of change analysis of floodplain.

Published: May 2024

The aim of the study is to characterize, from the point of view of geriatric aspects, the current problems of the organization of medico-social, palliative and hospice care (PHC) and social services for palliative care in the war conditions based on multidisciplinary, interagency and inter-sectoral approaches, as well as a combination of medical, psychological and social problems.
Materials and methods. The research materials were scientific literary sources and regulatory documents. A pilot survey of 200 people was conducted to study the psychological state and psychological support needs of the elderly and internally displaced persons (IDPs). The survey results of 3,705 client’s questionnaires of the “Vseturbota” Project were also evaluated, of which 63.6 % are people aged 67-84 years, 26.4 % are 85–101 years old. The following research methods were used in the work: bibliosemantic, sociological, system approach and system analysis.
Results and discussion. After February 24, 2022, IDPs will experience significant difficulties, suffer from reduced income, increased dependence on humanitarian aid, do not feel safe and protected. All these are reflected in their psychological state. It was found that among respondents aged ≥75 years had the most people with medium (57.1 %) and low (25.0 %) levels of anxiety, 71.4 % had a low level of mood. 32.17 % of the “Vseturbota” Project clients needed additional consultation with a family doctor, 3.83 % needed consultation with a psychologist, and 3.35 % with other specialists. Most often, they needed help around the house (26.02 %), buying medicines/foodstuff (22.43 %), 34.97 % needed information, and 13.36 % needed psychological counseling. An important condition for providing geriatric patients, including IDPs, with affordable, high-quality and effective PHC is the creation of a system and service of ambulatory/mobile and inpatient PHC facilities and medico-social care.
Conclusions. The military aggression of the Russian Federation caused considerable suffering to the population of Ukraine. The state of anxiety and fear has a negative impact not only on the psycho-emotional, but also on the physical sphere of the elderly, which necessitates the implementation of psychological services and effective strategies for overcoming stress and distress, which requires the development and implementation of mechanisms for interagency coordination and cooperation, involving and training of multidisciplinary teams’ specialists and volunteers, effective advocacy activities, etc.

Published: May 2024

The laboratory power supply is an indispensable device for the manufacture, testing, adjustment and repair of electronic equipment. The object of research is the process of selecting and justifying the device circuit on a modern element base, developing a printed circuit board, manufacturing and testing the created device layout in practice. The toroidal transformer of the required power was also calculated. The test was carried out in the voltage and current stabilization mode, and the data obtained indicate the possibility of further improvement of the device's circuitry. To build a laboratory power supply, it is desirable to use a linear circuit, because of the small pulsations that are critical when powering electronic equipment. A switching power supply can be used as an additional source when working with high-power circuits. A universal option is a bipolar power supply built according to a linear circuit with an output voltage of 0...±30 V and a current of 0...5 A. This solution will allow the device to be used for operation with most radio electronic devices, including those sensitive to RF noise, whose power consumption does not exceed 150 W. Thanks to the use of a bipolar circuit, it is also possible to work with high-quality audio frequency amplifiers that require bipolar power supply, operational amplifiers and some digital equipment. The galvanic isolation of the channels will make it possible to adjust the output parameters independently for each arm, which may be necessary when repairing digital equipment. Equipping the laboratory power supply with a current stabilization unit will make it possible to use the power supply as a battery charger and help in finding short circuits in circuits. Short-circuit protection will save the power supply in the event of an emergency and, in some cases, save the connected load.

Проблема чистоти повітря є надзвичайно актуальною для сучасної України, а саме, підтримки стану навколишнього середовища, життєдіяльності людини, перспективного розвитку промисловості країни. Забруднення повітря залежить від кількості викидів з різних джерел забруднення, до яких доєднались забруднення від військових дій. Причому наразі спостерігається досить низький рівень розвитку системи контролю стану навколишнього середовища. .Для вирішення питань, які постали у зв’язку з погіршенням екологічної ситуації в країні, є практична необхідність у створенні інформаційно-мобільних вимірювальних систем, в склад яких входять сучасні прилади з використанням продуктивних, точних і дешевих сенсорів для виявлення й вимірювання гранично допустимої концентрації забруднюючих речовин у повітрі статті надані наданні відомості щодо порівняльного аналізу, наявних на ринку України газоаналізаторів вуглекислого газу різних моделей. Згідно аналізу, запропонована інформаційна система вимірювання концентрацій токсичних, агресивних та отруйних газів, в склад якої входить газоаналізатор авторської розробки. Інформаційно-вимірювальна система поєднує в собі малі габарити, достатню точність вимірювання, простоту конструкції газоаналізатору та дешевизну складання. Було розроблено макет стенду інформаційно-вимірювальної система (ІВС), що надало можливість забезпечувати вимірювання складу повітря з використанням сучасних технологій.
