Published: December 2024

Abstract
The article presents the results of a research on the efficiency of multimodal grain transportation from Ukraine in the global supply chains. The research was conducted on the basis of the developed simulation model. Unlike existing ones the presented model takes into account the stochastic nature of the main technological operations and delays at the intersection point of different modes of transport. Using the developed simulation models, the process of transporting grains in global supply chains from Ukraine through the Mykolaiv Commercial Port was simulated. It was experimentally determined that the environmental impact of the multimodal route is significantly lower. CO2 emissions per ton of transported grains were 1 kg, which is almost 90 percent lower than when transported by the existing method.

Abstract
In the modern conditions of the ecological crisis, the study of adaptive changes in xerophyte plants, which form natural and cultural phytocenoses, has important theoretical and practical significance. Steppe phytocenoses of the Zaporizhia region, especially the Melitopol city and the Melitopol district, are represented by xerophytic associations. The research aim was to find out the histological and physiological rearrangements of the organs of the genus Elytrigia L. to determine adaptation features at the tissue level to water and temperature stresses. The subject of the study was the study of the structural and functional features of plant organs of the genus Elytrigia repens L. during adaptation to environmental factors (on the example of the Zaporizhzhia region, in particular the Melitopol city). The theoretical and methodological basis of the work was the synergistic use of a systemic approach, which led to a transparent approach to the choice of research methods, in particular: general scientific (analysis, synthesis, systematization, generalization of literary sources); general biological (experimental method, quantitative-anatomical, physiological and system-structural analysis, methods of mathematical statistics. It was established that the adaptation of xerophytes of the genus Elytrígia L. to arid habitats is characterized by structural and functional rearrangements of vegetative organs, in particular, the presence of unicellular trichomes, which ensures a decrease in transpiration, an increase in the share of storage tissues in the leaf and conductive and mechanical elements in the stem, as well as a decrease in intensity photosynthesis under drought conditions. As a result of finding out the functional disturbances in the leaf under the influence of drought, in particular the intensity of photosynthesis and the specificity of the pigment composition of the experimental plant, it was proved that the experimental plants under normal conditions have a parabolic curve of photosynthesis, and under the influence of atmospheric drought these indicators have a hyperbolic shape, and the analysis of the results of daily of the dynamics of photosynthesis established that the most intense photosynthesis occurs in plants under normal conditions, and under the influence of drought in plants there is a decrease and inhibition of the process of photosynthesis.

Abstract
The article is dedicated to the study of motivational profiles of employees, identifying dominant motives in conditions of war and uncertainty to develop the proper tools for directing personnel behavior toward reaching the goals of sustainable development. The study was conducted at bakery enterprises in the Sumy region of Ukraine in 2023. The methodological basis of the study is the author’s approach to structuring motives, which adapts the classic Martin and Ritchie methodology, sociological research methods (questionnaires, focus group surveys) and statistical analysis to the current conditions in Ukraine. As a result, the hypothesis regarding the dependency of the structure of motives (the image of the motivational profile) of employees on their position within organization and the nature of their work was confirmed. It was shown that management pays little attention to the development of motives directed at achieving sustainable development; at the same time, the very nature of work can serve as the basis for the behavior focused on sustainable development goals (for example, the value of work results for society). At the same time, it is apparent that the war changed the structure of motives: safety in the workplace instead of being just important becomes one of the key motives; the motives of social participation and psychological well-being of personnel acquired a greater weight. Unfortunately, though environmental behavior is understood and accepted as important in the structure of motives of employees, in the real motivational profiles it takes an average level, which indicates the impact of stress and war on the priorities as well as minimal efforts of company management in the development of “environmentally responsible” personnel. The obtained data became the foundation for the recommendations offered to improve staff motivation that include components relevant to the current situation of uncertainty and risks and are aimed at achieving sustainable development goals.
Interconnected roles of human capital, employment, and sustainable development in the EU countries
Authors: Kichurchak M V 
Published: December 2024

Abstract
Ensuring social stability and environmental sustainability is crucial for implementing the Sustainable Development Goals in European Union (EU) countries. This paper aims to explore the interdependencies among human capital, employment, and resource productivity in these countries, focusing on sustainable development. To comprehensively assess factors influencing sustainable development in the EU countries, the simultaneous model is proposed. The simultaneous equations were derived using a two-step least squares method. The model comprises three endogenous variables (human capital, quantified by students enrolled in tertiary education; employment, in terms of the resident population concept; and resource productivity) and ten exogenous variables. The human capital pillar for the EU countries hinges on public funding for tertiary education, the employment dynamics for tertiary-educated individuals, resource productivity, environmental taxation, and emigration. Employment requires monitoring demographic trends, resource productivity, government funding for tertiary education, and environmental taxation. The environmental pillar depends on employment dynamics, GDP per capita, public funding for environmental protection, material resource extraction, and direct material inputs of fossil energy materials. For Austria, Belgium, and Portugal, from 2013 to 2021, the theoretical values based on the structural model of sustainable development demonstrated good forecast accuracy for human capital, employment, and resource productivity, indicating positive dynamics.

Published: December 2024

Abstract
Lime is used in the classical copper-molybdenum-pyrite flotation for pyrite depression. Often copper-molybdenum flotation separation is conducted with nitrogen and copper minerals are depressed with the aid of phosphorus- or sulfide-based compounds. The mentioned methods are relatively expensive, difficult for handling, sometimes desired results are not achieved and valuable metals are lost. An electrochemical depression of pyrite, followed by an electrochemical depression of copper minerals is suggested and aimed at increasing the recovery of metals and improving the processes’ control. The impact is achieved both by electrodes immersed in the flotation pulp or by using preliminary produced catholyte for pulp preparation. Effective copper-pyrite and copper-molybdenum flotation separation can be achieved under air conditions at significantly reduced amounts of reagents used, latter leading to improved environmental impact.

Abstract
The article is dedicated to Internet of Things (IoT) technologies that allow connecting various devices and sensors via the Internet. Effective customer interaction with IoT systems requires smart interfaces that take into account the context and human needs. Chatbots are considered that can provide users with convenient support, process data from sensors, and visualize them. An IoT system consisting of sensors, a cloud platform for data storage and processing, a database, and a chatbot interface for user interaction is considered. The automatic indoor temperature control system uses sensors that transmit data to the cloud, where it is processed and stored. Users can interact with the IoT system through a chatbot that understands commands and responds accordingly. The chatbot has been tested, showing that it can autonomously maintain the optimal temperature, changing it according to user commands, and responding to critical situations. The results of the study demonstrated that the use of a chatbot allows you to create a human-centered automated system.
Modeling of cone crusher steady-state operation modes
Authors: Mykhailenko O 
Published: December 2024

Abstract
The design of complex technological processes control systems involves several stages. One of the first is to analyze the steady-state operation modes of the control plant. Ore crushing is one of the most critical processes in mineral processing. The quality of its control determines the level of power consumption not only at this stage of mineral processing, but also at the subsequent ones, especially the grinding processes, which are the most energy-intensive in the entire production. The size and homogeneity of crushed ore significantly affect the power consumption of the mills. Ore is crushed by cone crushers. The crushing process is characterized by a large number of parameters. Depending on the control purpose, any of them can be considered as an input, output or disturbance. As a result, a cone crusher as a control plant is a multi-input multi-output system. The relationships between inputs and outputs are very complex, so it is very important to have an adequate mathematical description of cone crusher steady-state for its quality control. In this article, it has identified second-order polynomials regression models for the dependencies between the most significant parameters for a typical cone crusher with a mantle width 2200 mm. Namely, the dependence of the crusher electric drive power on the closed-side setting and feed capacity; the percentage of the control particle size class in the product on the closed-side setting and product capacity; product capacity on the closed-side setting, lining wear on the product capacity. The least squares method was used to estimate the parameters of the regression models.

Published: December 2024

Abstract
Dam monitoring is an effective method of the management of risk associated with dam operation. Interpretation of monitoring data is an essential part of the monitoring procedure. The main purpose of data interpretation in dams is the well-timed detection of hazardous conditions. Since numerical modelling such as finite element modelling method (FEM) is based on physical equations, it can provide results that can be converted into diagnosis. The application of the numerical modelling for monitoring data interpretation in earth dams in the view of uncertainties specific for dam operation and monitoring is studied with the purpose of obtaining the interpretation results that will be practically valuable for intervention planning. In this study the application of one of the techniques of numerical model calibration for the series of alternative diagnoses for real dam monitoring data interpretation is presented. For reducing the uncertainty, the probabilistic estimations of the alternative diagnoses were inferred with the use of Bayes’ rule. The technique applied provides a visually clear representation of the possible diagnosis for the practical decision making.

Abstract
Hydrological indicators are important in shaping the ecological status and economic potential of surface water bodies. Industrial facilities that consume water can change the hydrological and temperature regimes of water bodies. The purpose of this study was to investigate the impact of water use and consumption for the Rivne Nuclear Power Plant (RNPP) on alterations of indicators of the hydrological and temperature regimes of the Styr River. The study revealed patterns of changes and analyzed the hydrological indicators of the Styr River under water use and consumption by the RNPP, and the temperature regime of the Styr River in the RNPP impact zone, revealed patterns of dynamics of water use and consumption for the RNPP, determined the correlation between the Styr River discharge and the RNPP water discharge in the hydrological regime of the Styr River. The range of variability approach was used to assess of the Styr River hydrological alteration in the RNPP impact zone. During the warm seasons of 2019 and 2020, the Styr River experienced periods of low water flow. A strong positive correlation (r = 0.7 – 0.9, R
2 = 0.7623, p <0.0001) was found between water use and consumption at RNPP and the temperature of Styr River water. Additionally, a very strong positive correlation (r = 0.9934, R
2 = 0.9869) was found between the temperature of Styr River water before and after discharge. Furthermore, it is observed that during the warm season, there is an increase in water consumption and discharge costs for RNPP. Thus, the results of the study indicate that there is no impact of RNPP water discharge, and therefore no measures to improve the condition of the Styr River are required.
Risks of the soil foundations stability losses of the Kyiv-Pechersk Lavra Dormition Cathedral due to the urban activities
Authors: Kril T V , Cherevko I A 
Published: December 2024

Abstract
In the research, the use of numerical analysis of the soil foundations stability losses of Dormition Cathedral, where in the interiors of the II tier northern part, deformations of structural elements have been recorded since 2016, probably caused by uneven settlement of the foundations due to overmoistening. The initial data were the results of constant monitoring of the technical condition of the building, engineering and geological investigations, etc. To determine (confirm) the deformation factors and forecast their activation stabilization, a numerical calculation of the stress-deformation state of the cathedral soil foundations was performed for soils in their natural state and water-saturated state. The calculations of the stress-strain state of the cathedral foundations and the determination of plastic deformation zones were done using the PLAXIS software complex. They showed an increase in deformations in its northeastern part, under the basement premises, in particular for the scenario of flooding of the underground part. According to calculations, the plastic deformations of the base soil and, as a result, the deformations of structural elements are still in the stage of incomplete stabilization in the northern part of the cathedral, in the area where the basement part is located. The deformations extend the entire pile field under the construction of the cathedral, but do not reach the extreme minimum values in 8 cm. The main factor in the activation of deformations is the overmoistening of the soil massif, the impact of blast waves is not excluded (confirmation of which requires vibration monitoring). The direction of improving protection management measures for Dormition Cathedral is proposed.

Published: December 2024

Abstract
This article explores strategies for ensuring the autonomous operation of Renewable Energy Communities (RECs) in Ukraine, aligning with the ongoing reform in the country’s energy sector. The reform emphasizes the implementation of promising autonomous decentralized systems, potentially leading to the establishment of RECs. These initiatives aim to incorporate low-capacity sources in providing electricity during autonomous conditions or outages. Examining data on small electricity producers reveals the prevalence of solar power plants, the emergence of micro-hydro plants, and limited representation of wind power. The article also underscores the increasing significance of biogas in electricity production. Furthermore, it explores the formation of RECs as a contemporary decentralized solution, requiring a thorough analysis of sustainability for autonomous operation. The utilization of various generation types in the structure of RES (renewable energy sources) communities enables the adaptation of electricity generation to dynamic conditions, ensuring system resilience in the face of failures or challenges associated with a predominant generation source. The core focus shifts towards optimizing existing hybrid systems encompassing different renewable energy sources. This involves analyzing load and capacity distribution, technological profiles, and integration strategies for RECs into the power grid, ultimately contributing to the enhancement of Ukraine’s energy security. The proposed approach involves mathematical modeling of low-power hybrid renewable systems that derive electricity from RECs. This modeling incorporates generation characteristics, objective functions, and constraints to facilitate multi-criteria decision-making. The results underscore the significance of exploring diverse scenarios and combinations of generating sources, taking into account resource potential, electricity generation variability, operating costs, and other factors. This holistic approach allows for the optimization of the RES community structure, striking a balance between reliability and cost considerations.
Analysis of the current state and the future prospects of renewable energy in heating and cooling systems in Ukraine
Authors: Lysak O V 
Published: December 2024

Abstract
Currently, there is significant focus on the transition to green energy, particularly in achieving climate neutrality. The European Green Deal outlines one of the main approaches in this field, which is being implemented in the EU. As Ukraine aims to become an EU member, it would be beneficial to consider adopting renewable energy solutions, especially in heating and cooling systems, in order to align with the EU’s efforts towards sustainability. The statistical analysis of the field shows that Ukraine’s share of renewable energy is two and a half times less than that of the EU, but it still exceeds that of three EU member states. It is worth noting that the majority of renewable energy for heating in Ukraine is generated by biomass, which is considered less economical and ecological compared to heat pumps. At present, there is a notable interest in increasing the proportion of renewable energy used for heating and cooling, with heat pumps being the primary focus. Various methods are being investigated to facilitate the adoption of heat pumps, including government assistance to reduce system costs and step-to-step realisation in cases of limited financial resources.
