The object of the study is the distributed generation (DG) system for remote areas where extending power lines is challenging or impossible. The study demonstrates how integrating electrical and thermal energy modules based on renewable energy sources (RES) into a common DG bus can ensure continuous energy supply. This approach provides both heat and electricity to consumers, independent of weather conditions an advantage over traditional systems reliant on variable sources like wind and solar energy. Numerical assessments suggest that the proposed system can improve local renewable resource utilization by approximately 20–30 % compared to singlesource renewable setups. This enhanced efficiency results in a more stable power output, with fewer interruptions caused by low wind speeds or reduced solar irradiance. Economically, reducing dependence on diesel generators by about 15–25 % can translate into substantial fuel cost savings. In addition, shifting energy production away from nonrenewable sources may cut greenhouse gas emissions by an estimated 10–20 %, contributing to environmental protection targets. In this research received lies in its solution for offgrid energy delivery in rural areas, which generally rely on expensive and frequently unreliable centralized energy infrastructure. By leveraging renewable energy sources and implementing a cogenerative DG system, the study significantly reduces reliance on traditional energy grids and enhances energy independence for remote facilities. The research highlights the practical value of the proposed solution, particularly for rural areas far from power lines and with limited access to traditional electricity systems. The suggested system not only provides continuous energy, but it also coincides with worldwide trends toward sustainable and decentralized energy solutions

Learning a foreign language has become a necessity in modern society's development. The knowledge of foreign languages contributes to the adaptation of a person to rapid changes in world society. In modern conditions, there is an urgent need for highly educated people with critical thinking skills who would be able to analyze a large flow of information and make informed decisions. To achieve this, it is necessary to pay great importance to the quality of education. The methodology of foreign language education is closely interrelated with didactics as both sciences study the educational process. As it is known, didactics considers the educational process as a whole, and the methodology of foreign language education deals with studying a specific subject and identifying the features of foreign language education. The main function of a foreign language in school is the formation of communicative competence, that is, to teach students to communicate to transmit the information received in a foreign language. In foreign language lessons, educational goals are realized while students solve communicative tasks, and patriotic feelings and feelings of tolerance for their own and foreign cultures are formed and developed among students. When learning a foreign language, harmonious personality development occurs, and her horizons expand. The purpose of foreign language education is to develop the student's potential, which determines the humanistic direction of modern education (Borisenkov, 2004). © 2023, Slovenska Vzdelavacia Obstaravacia.

One of the main methods of natural water and wastewater treatment is coagulation. Water purification from suspended solids is very difficult due to their small particle size and flocculation stability. In many cases, enhancement of these processes can be achieved by enlargement of the particles in flocculence under the action of flocculants, especially mixtures (mixing) of them. Both pure chemical salts and mineral raw materials are used as initial raw materials for flocculants. The technique of obtaining coagulant from mineral raw materials (alunite, nepheline, slag, ash and clay, bauxite) and unconditioned natural ores that are considered technical waste is much cheaper than obtaining reagents from pure chemical salts. A technology is presented that simultaneously solves the problem of obtaining low-cost, cost-effective alumina iron coagulant and reducing bauxite mining waste. This information is confirmed by the study of the physicochemical and thermodynamic conditions of the process, the validation of mathematical models, and estimated data on the efficiency of industrial wastewater treatment when a given coagulant is applied. This scientific paper presents original research on the development of coagulants-flocculants based on sulfate-chloride alumina coagulants and substandard bauxite. The novelty of the work lies in the selection of substandard materials for the extraction of effective coagulant products. © 2025, Kauno Technologijos Universitetas. All rights reserved.

In recent years, the escalating challenges of noise pollution in urban environments have necessitated the development of more sophisticated sound detection and classification systems. This research introduces a novel approach employing a Convolutional Long Short-Term Memory (ConvLSTM) network tailored for real-time impulsive sound detection in metropolitan landscapes. Impulsive sounds, characterized by sudden onsets and short durations—such as honking, abrupt shouts, or breaking glass—are inherently sporadic but can significantly impact urban soundscapes and the well-being of city dwellers. Traditional sound detection mechanisms often falter in identifying these ephemeral noises amidst the cacophony of urban life. The ConvLSTM network proposed in this study amalgamates the spatial feature learning capabilities of Convolutional Neural Networks (CNN) with the temporal sequence retention attributes of LSTM, culminating in an architecture that excels in both sound detection and classification tasks. The model was trained and evaluated on a comprehensive dataset sourced from various urban settings and demonstrated commendable proficiency in discerning impulsive sounds with minimal false positives. Furthermore, the system's real-time processing capabilities ensure timely interventions, paving the way for smarter noise management in cities. This research not only propels the frontier of impulsive sound detection but also underscores the potential of ConvLSTM in addressing multifaceted urban challenges. © (2023), (Science and Information Organization).
