Authors: Prušević Sadović Filduza , Demirović Esma , Trtovac Dedeić Alma , Karaahmetović Hana
Published: January 2025

Modern times have changed the way children play. Starting from the fact that play is a basic activity for children through which children learn and develop, we wanted to get acquainted with new games that have moved from the real world to the digital environment. The paper presents the results of a research whose subject was the intensity and frequency of playing digital video games, as well as a description of the most frequently played games in younger school age. Through research, we became familiar with the games Roblox and Stumble Guy, which are the most popular among the target group, their content, and the way they play. By directly playing these games, we explored their potential educational aspects. The research shows that children of younger school age spend between one and three hours a day playing these games, that they like to play synchronously with their peers the most, and that the most frequently played games have common features such as competitions to achieve certain goals, attractive graphics and modest educational values.
The Use of Digital Technologies and Learning in a Digital Environment: An Example of Students at the University of Novi Sad
Authors: Vojčić Gorana , Bosanac Maja
Published: January 2025

Analog learning environments are often combined with, or in some cases completely replaced by digital environments – a trend that has been particularly accelerated during the COVID-19 pandemic. To gain insight into students’ perceptions, practices, and experiences regarding the use of digital technologies and learning in digital environment, a qualitative study was conducted employing in-depth interview techniques. The research sample consisted of 14 students from the University of Novi Sad, with equal representation from the different fields: social sciences and humanities, natural and mathematical sciences, technical and technological sciences, medical sciences, and the arts. By exploring students’ perspectives, our study aimed to contribute to the body of research conducted in the post-pandemic period. The research results were interpreted within four sections, starting with an examination of the broader context and the use of digital technologies in students’ daily lives, including entertainment and relaxation, communication and connectivity, and extending to information and learning. The second section focuses on the use of digital technologies in the context of learning, while the third section is dedicated to the application of digital technologies and learning in a digital environment during the teaching process. Following this, the study explores perceptions and possibilities for the coexistence of different teaching models. Based on the reviewed literature and the results of the conducted research, the conclusion is drawn that the pandemic, as a contextual factor, potentially influenced students’ negative attitudes toward online education, given that it was a case of “emergency remote education” rather than planned online education. On the other hand, the primary purpose of using digital technologies and learning in digital environment is identified as accessing learning materials.In this context, the study of Open Educational Resources (OER) may gain increasing importance in the future. Although all students report using digital technologies in the context of learning and teaching, differences in the scope, frequency, and manner of their application are noticeable. Among the variables studied, affiliation with a specific field of study was found to be more relevant for participants’ responses compared to gender and average grade.
Motivation for Choosing Studies Among Psychology Students, Foreign Languages Students and Their Life Satisfaction
Authors: Dragišić Ljubica , Pavlović Zlatko
Published: January 2025

As factors that significantly influence students to choose psychology studies, sources often cite the need to help others and the desire to understand people and their behaviour in the literature. One of the reasons for choosing a study program is generally pragmatic reasons. On a smaller sample of students that consisted of students studying psychology and students studying foreign languages (N = 158), we investigated whether could identify three types of motivation for choosing a study based on the three needs mentioned (needs to help others, needs to understand people and their behaviour, and pragmatic needs). Motivation for the choice of study was measured with a self-constructed scale, while life satisfaction was measured with the Satisfaction With Life Scale (SWLS). In psychology students we identified all three types of motivation, while in foreign language students we identified pragmatist motivation for choice of studies and the other two components of motivation did not appear as separate factors, but formed one factor. Life satisfaction was unrelated with any type of motivation among psychology students, and in the other group of students it showed a slight correlation with pragmatic motivation. In pragmatist motivation, the difference between the two subsamples of students was not registered, while in life satisfaction it was. Psychology students showed higher life satisfaction.

Authors: Tankosić Mirjana , Manić Ljiljana , Mikić Andrijana
Published: January 2025

The research examines effective communication strategies in higher education, focusing on their role in improving the market positioning of higher education institutions (HEIs). The study explores key communication channels, such as social media, email marketing, and events, with-in comprehensive marketing strategies. The results highlight the importance of tailoring communication to specific target audiences, including prospective students, current students, and alumni. The research analyzes student perceptions and satisfaction with their academic experience at the College of Social Work in Belgrade, using the Net Promoter Score (NPS) as a key metric for service quality evaluation. Findings indicate that flexibility in study options and the quality of teaching staff are critical factors in student satisfaction, while the institution’s website had a significant influence on student perceptions. In contrast, social media played a lesser role in student engagement. The conclusions emphasize the need for tailored com-munication strategies to attract and retain students.
Self-Assessment of Social Work Students’ Competence Development for Working with Marginal Groups
Authors: Gadžo-Šašić Sabira
Published: January 2025

According to the definition of the International Federation of Social Workers (IFSW), social work is a practice-based profession and academic discipline that promotes social change and development, social cohesion, and the empowerment and liberation of people. Underpinned by the theory of social work, social and humanistic sciences, and indigenous knowledge, the profession of social work engages people and structures to solve life’s challenges and increase well-being. However, the continuous negative changes that have characterized modern societies pose a challenge to social workers in particular in finding solutions for increasingly complex social situations that are especially faced by marginal members of society. Such a context imposes the necessity of continuously developing the competencies of those who are being educated for the profession of social work. Therefore, the aim of the paper is to gain insight into students’ views on the level of competence development during studies for working with marginalized groups, and on who they consider the most marginalized members of the community. In this connection, a survey was carried out, which included 50 students of the Department of Social Work, Faculty of Political Sciences, University of Sarajevo. The key findings are that students, or future social workers, believe that the most marginalized are the Roma, people with disabilities and children with developmental disabilities, but that young people are the group they would most like to work with as social workers. It was also learned that the reasons for such a determination are: insufficient resources for providing assistance; the impossibility to approach every individual due to the lack and insufficient involvement of actors important for improving the position of the most marginalized groups. Also, slightly less than half of the participants in the research (23 or 46%) emphasize the importance of organizing additional education as a form of continuous development of competences, which is especially important in a time of ubiquitous negative changes.
Students on Strategies and Approaches for Improving University Project-Based Learning in the Prevention of Gender-Based Violence
Authors: Kovačević Branka
Published: January 2025

The literature review finds gender-based violence to be a form of violence based on gender, that is, on socially constructed roles, norms, and relationships between women and men. Gender-based violence refers to physical, emotional, economic, and sexual violence, and it often occurs in the context of power and control. University project-based plays a crucial role in supporting the internal initiative to raise awareness of the importance of gender issues. It can include different strategies and approaches related to defining goals, analyzing the current situation, implementing the project, and evaluating its quality. The study aimed to determine and analyze the level of student assessment of strategies and approaches for improving university project-based learning to prevent gender-based violence and to determine statistically significant differences in assessment between students of social sciences, arts and humanities, and natural sciences and engineering. The research was conducted on a sample of 303 students at the University of East Sarajevo. For this research, we constructed a scale for assessing strategies and approaches to improving university project-based learning to prevent gender-based violence. The results show that there are statistically significant differences between students of social sciences and arts and humanities on the one hand and natural sciences and engineering on the other hand in the assessment of strategies and approaches to improving university project-based learning in the prevention of gender-based violence, i.e., the application of an interdisciplinary approach in university project-based learning, research and case studies, organizing workshops and discussions, cooperation with the local community and networking with other educational institutions. Strategies and approaches to improve university project-based learning act as prevention because they enable students to acquire skills for active participation in promoting gender equality and for creating a society tailored to everyone who lives in it.
Verb Constructions (u)činiti (se) + Noun or Adjective of Foreign Origin in Parry-Lord’s Collection
Authors: Ćušić Tarik
Published: January 2025

The paper analyzes the verb constructions composed of the verb with incomplete meanings(u)činiti (se) and nouns or adjectives of foreign origin as lexical meaning in Bosniak epic poems using the example of Parry-Lord’s collection from 1953. Such constructions in the verse structure fill the position of the predicate, either decomposed (verb + noun) or semi-copulative (verb + adjective), and are one of the characteristic features of the oral epic style. The conducted research confirms that the adjectives in these predicates are invariably of oriental origin, and the nouns are mostly of oriental and rarely of Italian and Albanian origin. The purpose of the analysis is not only to give a description of these constructions, but also to explain the reasons for their high frequency. Their frequent use in epic poetry is a reflection of the desire for simplicity, which epic singers fulfill by using traditional patterns of epic formulas: by replacing one noun or adjective with another same syllabic noun or adjective in these constructions the formulas of the second half-verse are very easily created. The simplicity of using these constructions in composing verses favors the frequency of their use. The list of all those constructions from the selected corpus is given in the form of a dictionary article, the structure of which includes an accented determiner, an etymological determiner, an indication of the type of word, a lexicographic (stylistic) determiner, a description of the meaning and an example.
Enhancing Business English Specialised Terminology Learning through Game-Based Instruction
Authors: Mebitil Nawal , Abderrahmane Djahida
Published: January 2025

Learning new terminology is often regarded as the cornerstone of ESP. Its acquisition is vital for ESP practitioners and learners to facilitate communication in different target situations. The practitioners ‘ prime concern is searching for an adequate way to facilitate this task for ESP learners. At this level, the use of educational games belongs to the strategies that are challenging and beneficial for the teacher, and engaging and captivating for the students. Therefore, the present study aims to test the impact of educational games on acquiring specialised terminology among Business English students at Mustapha Stambouli – Mascara University, Algeria. A semi-structured interview, a questionnaire, and a pre-and post-test under the umbrella of the mixed methods approach were used as research tools to gather the required data. The results revealed that teachers and students acknowledge the positive impact of the game-based approach on their ability to acquire and memorise specialised Business English terminology. Also, educational games are essential in creating a friendly, competitive, and authentic environment in which they wish to be involved. For them, this approach enhances their language proficiency and the required communication skills to function adequately in their target settings. These findings suggest that incorporating educational games can be perceived as an essential element that should be further consolidated in different ESP contexts, including the business one.
Ruin as the State of a City under Siege
Authors: Mandić Asja
Published: January 2025

The notion of the city as a ruin, in the case of besieged Sarajevo (1992-1996), extends beyond mere material destruction and diverges from the conventional meanings of ruins found in theoretical discourse and literary expressions – such as the aestheticization of death and decay and the romantic tranquility evoking feelings of nostalgia. In Sarajevo, ruin refers to a profound physical and psychological state resulting from fragmentation, disintegration, and the desecration of its urban fabric. This encompasses not only the literal reduction of certain buildings to ruins but, more significantly, the strategic incapacitation of the city as a social organism and the annihilation of everything that defines it as a modern and civilized place. Urban space, through its artifacts, concentrates and embodies history, memory, meaning, and symbols; it is designed to gather people and facilitate communication. However, this fundamental quality was systematically destroyed during the four years of the siege. The essence of the city, as a means of organizing society, facilitating interaction among diverse elements, and connecting them, was being increasingly undermined. While Sarajevo was not completely physically devastated, it can still be viewed as analogous to ruin in many ways. This comparison ties into the language used to describe its wartime state, evoking themes of decay, abandonment, neglect, transience, and the temporality of both building and living.
Ethnic Divisions and Power Politics: Unravelling the Barriers to Managing Diversity and Democratization in Post-Conflict Bosnia and Herzegovina
Authors: Arapović Adis
Published: January 2025

This article critically investigates the factors leading to the stagnation of democratization and the persistence of societal divisions in post-conflict Bosnia and Herzegovina (BH), with a particular focus on the role of political elites. Employing a mixed-methods approach, the research combines historical comparative analysis with qualitative content analysis of political developments, media reports, and public statements. The research uncovers that political elites in BH have systematically exploited and deepened ethnic divisions as a means to consolidate and maintain power supporting the hypothesis that insufficient success in managing diversity is influenced by the interests of political elites to maintain political power through ethnic divisions. This process of homogenizing ethnic groups for political leverage is identified as a significant barrier to democratization and societal integration. The study also examines the lingering effects of ex-Yugoslav socialism and regional geopolitical influences, particularly the relationships with Serbia and Croatia, in shaping the nation’s political and ethnic landscape. The main findings highlight that the deliberate actions of political elites, aimed at reinforcing their power bases through ethnic polarization, are the principal contributors to the failed democratization and the continuation of a divided society. The study underscores the necessity for policy interventions that target the root causes of ethnic division, emphasizing the need for political reforms that diminish the power of elites to manipulate ethnic identities for their gain. These insights are vital for understanding the challenges in BH and offer valuable lessons for other post-conflict and multi-ethnic societies grappling with democratization and ethnic reconciliation.
A Critical Analysis of US Official Discourse on Pakistan vis-a-vis Afghanistan under the Biden Presidency
Authors: Nousherwani Shahzad Dastgir , Maksić Adis
Published: January 2025

Language is important in the formulation and construction of perceptions regarding allies and foes. In the case of US-Pakistan relations, conflicting themes based on oxymorons have been routinely used to depict the inherent complexities and contradictions in the relations. Using the theoretical framework of discourse analysis, this paper critically analyzes the corpus of US official discourse on Pakistan on the issue of Afghanistan under the Biden Presidency. The corpus of official statements is analyzed with reference to the wider US political culture as well as previous ‘texts’ / older discourse, thereby creating a degree of intertextuality. In this regard, the US official discourse shows four major themes, some of which are in tension with others, which inform overall US-Pakistan relations. They are also, in part, reflective of the tensions within US policies in the region and the War on Terror.
Local Self-Government in Bosnia and Herzegovina - Analysis of the Normative Framework Through the International Standards with Special Reference to Citizen Participation
Authors: Kotlo Rebeka , Tomić Ivan
Published: January 2025

In the article, the authors analyze the normative framework of local self-government in Bosnia and Herzegovina according to international standards with special reference to citizen participation. The authors analyze the normative regulation of local self-government along with the relevant acts of the Congress of Local and Regional Authorities that refer to Bosnia and Herzegovina. In addition to the existing normative framework, the authors examine the possibilities of applying deliberative democracy through the analysis of the pilot project Development of Democratic Participation in the City of Mostar and the possibility of introducing electronic democracy mechanisms. The results of the research indicate that the basic problems in the functioning of local self-government are reflected in a complex multi-level normative framework, an inadequate system of local self-government financing, and insufficient use of existing democratic mechanisms that promote citizen participation in local self-government units. In order to make more efficient use of existing mechanisms and strengthen citizen participation, the authors suggest the implementation of unconventional models of democracy, deliberative and electronic democracy. The implementation of these mechanisms could strengthen the democracy of local self-government and contribute to the strengthening of public trust in local government.

Authors: Grundy Quinn , Hart Dana , Elkhalifa Sarah , Lexchin Joel , Gagnon Marc-André , Persaud Navindra , Tadrous Mina
Published: January 2025

Historically, medically necessary infusion services were provided within publicly funded hospitals under the Canada Health Act. In the early 2000s, pharmaceutical manufacturers set up third-party private infusion clinics to facilitate patient access to new IV drugs.
This descriptive, cross-sectional study identified all infusion clinic locations in Canada and summarized their ownership, settings, amenities, and types of medicines infused.
A total of 1,097 infusion clinics were identified that provided outpatient care for people prescribed IV medications. Approximately half of the clinics were owned by private entities and funded through manufacturers’ patient support programs, private insurance, or out-of-pocket by patients.
Of the clinics offering infusion services for biologics and cancer immunotherapy, more than 85% were private, for-profit companies, whereas 99% of clinics providing chemotherapy or blood products were in the publicly funded system.
The findings highlight the need for further research into clinic operations and care outcomes to inform government policies on the optimal degree of private sector involvement and strategies to ensure equitable and sustainable access to medically necessary care.

Effect of dietary protein level and lamb breed on meat physicochemical traits, fatty acid profile and nutritional indices
Authors: Hajji Hadhami , Smeti Samir , Mekki Ilyes , Atti Naziha
Published: January 2025

Abstract. Special attention is increasingly given to food characteristics, particularly fatty acid (FA) profile. The quality of meat, as food of animal origin, depends on animal genotype and feeding. This study evaluated the meat quality and FA profile of three Tunisian sheep breeds, i.e. Barbarine (BB), Queue Fine de l'Ouest (QFO) and Noire de Thibar (NT), under diets with low (11 %) or high (16 %) crude protein (CP) levels, aiming to optimize feeding strategies for Tunisian sheep production. Lambs were slaughtered at 51 kg body weight. The longissimus-thoracis et lumborum muscle was extracted for meat quality analysis. The intramuscular fat was higher for QFO than other breeds. The meat FA profile was not affected by CP level but was affected by sheep breed. The C16:0 FA was higher for QFO than the two other breeds, which had higher C18:0 FA (17.7 vs. 14.6 %). The n−3 and n−6 polyunsaturated FA (PUFA) contents were higher (P<0.001) for meat of fat-tailed BB than other breeds, resulting in a higher total PUFA and higher PUFA / SFA ratio (0.135 vs. 0.09, where SFA represents saturated fatty acid). The atherogenic index (AI) and cholesterolemic index (h/H) of the meat were in the recommended ranges, being in favour of BB and NT breeds with, respectively, lower and higher values than QFO. However, the thrombogenic index (TI) was high and similar among breeds. In conclusion, the FA profile and lipid indices in sheep meat were primarily influenced by breed, with no significant effect from crude protein level, suggesting that a low-protein diet can yield comparable meat quality to a high-protein diet.
Regional-scale groundwater analysis with dimensionality reduction
Authors: Somogyvári Márk , Brill Fabio , Tsypin Mikhail , Rihm Lisa , Krueger Tobias
Published: January 2025

Abstract. Given the importance of groundwater for freshwater provision and groundwater-dependent ecosystems, understanding climate effects on groundwater changes at a regional scale is essential. In this paper, we propose a new way of applying dimensionality reduction for such purpose, not over the collected data, nor over any calibrated models, but over the misfits between the modeled and observed groundwater levels. This methodology highlights local differences in climate-groundwater relations and can be used to identify regions with different vulnerabilities in a data-driven way. The approach takes gridded groundwater level data and gridded precipitation and evapotranspiration data as input. Linear water balance models are set up for each grid cell in an independent way. The misfits between the water balance model simulations and groundwater levels are used for the dimensionality reduction-based regionalization, with which areas of different groundwater behavior are identified. We demonstrate the potential of our methodology in the Berlin-Brandenburg region, Germany, where groundwater is a major freshwater source at risk. We show that groundwater level changes are linearly related to climatic variations at a monthly scale, even in areas with strong anthropogenic influences. The dimensionality reduction further reveals an approximate regionalization of groundwater behavior, which can be used as a basis for more detailed investigations.

Abstract. Leaf area index is an important metric for characterising the structure of vegetation canopies and scaling up leaf and plant processes to assess their influence on regional and global climate. Earth observation estimates of leaf area index have increased in recent decades, providing a valuable resource for monitoring vegetation changes and evaluating their representation in land surface and earth system models. The study presented here uses satellite leaf area index products to quantify regional to global variations in the seasonal timing and value of the leaf area index trough, peak, and amplitude, and evaluate how well these variations are simulated by seven land surface models, which are the land components of state-of-the-art earth system models. Results show that the models simulate widespread delays, of up to three months, in the timing of leaf area index troughs and peaks compared to satellite products. These delays are most prominent across the Northern Hemisphere and support the findings of previous studies that have shown similar delays in the timing of spring leaf out simulated by some of these land surface models. The modelled seasonal amplitude differs by less than 1 m2/m2 compared to the satellite-derived amplitude across more than half of the vegetated land area. This study highlights the relevance of vegetation phenology as an indicator of climate, hydrology, soil, and plant interactions, and the need for further improvements in the modelling of phenology in land surface models in order to capture the correct seasonal cycles, and potentially also the long-term trends, of carbon, water and energy within global earth system models.
Global terrestrial moisture recycling in Shared Socioeconomic Pathways
Authors: Staal Arie , Meijer Pim , Nyasulu Maganizo Kruger , Tuinenburg Obbe A. , Dekker Stefan C.
Published: January 2025

Abstract. Many areas across the globe rely for their precipitation supply on terrestrial precipitation recycling, which is the amount of precipitation that has evaporated from upwind land areas. Global warming and land-use changes may affect the future patterns of terrestrial precipitation recycling, but where and to which extent remains unclear. To study how the global patterns of precipitation recycling may change until the end of the 21st century, we present a new forward-tracking version of the three-dimensional atmospheric moisture-tracking model UTrack that is forced by output of the Norwegian Earth System Model (NorESM2). We simulate global precipitation recycling in four Shared Socioeconomic Pathways (SSPs) which are internally consistent combinations of climate and land-use scenarios used in the sixth phase of the Coupled Model Intercomparison Project. The scenarios range from mild to severe, namely SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5. We compare results for the middle of the century (2050–2059) and the end of the century (2090–2099) with a 2015–2024 baseline. We also calculate basin precipitation recycling for the 26 major river basins of the world. We find that the global terrestrial precipitation recycling ratio decreases with the severity of the SSPs and estimate a decrease in this ratio of 1.5 % with every degree of global warming. However, we find differences among regions and river basins in trends in precipitation recycling and whether projected drying or wetting is mainly contributed by land or ocean. Our results give critical insight into the relative contributions of global warming and land-use changes on global precipitation changes over the course of this century. In addition, our model paves the way for more detailed regional studies of future changes in terrestrial moisture recycling.

Tanaman Obat Keluarga (TOGA) adalah jenis tumbuhan yang dapat meningkatkan kesehatan yang efektif mengobati penyakit tanpa menimbulkan efek samping negatif. Membudidayakan tanaman obat di rumah sebagai sarana pemanfaatan tanaman obat yang sudah ada untuk melakukan pencegahan atau pengobatan secara mandiri dikenal dengan sebutan Tanaman Obat Keluarga (TOGA) atau Apotek Hidup. Bagi keluarga yang sulit mengakses layanan kesehatan, memiliki tanaman obat keluarga sangatlah penting. Untuk menjamin masyarakat dapat memanfaatkan tanaman obat dengan baik dan benar, tim Kuliah Kerja Nyata (KKN) Universitas Negeri Padang membuat program perbaikan gedung TOGA dan peningkatan pemahaman masyarakat tentang tanaman obat keluarga. Metode yang digunakaan adalah pendekataan analisis kualitatif dan metode pelaksanaan adalah pengabdian masyarakat, Selain itu pendekatan ini jugamelakukan observasi langsung dan indepth interview melalui pihak- pihak yang terkait dalam penelitian tersebut. Hasil penelitian dan pengabdian tim Kuliah Kerja Nyata (KKN) UNP yangtelah dilakukan di Jorong Bonai, yaitu meningkatnya kesadaran masyarakat untuk menjaga kebersihan TOGA dan masyarakat dapat menggunakannnya dengan baik

The aim of the work is to study the processes of injecting gas-powder jets into a liquid bath on cold models and determine the processing parameters. To implement the cold modeling, an installation was mounted at the laboratory base of the Institute of Ferrous Metallurgy, which provides a controlled reagent injection. The reagents used were soda, lime, and iron (II) oxide. The simulation was carried out with the reagent being dispensed into a dry container and into a container with water, which was an imitation of a ladle. Before pouring the reagent into the dosing device, sieving was performed, the mesh diameter of the smallest sieve was 1 mm. A surfactant was also added to the reagent to improve the movement of the reagent. During the operation of the installation, the readings of the manometers installed on the gas carrier outlet route and on the dosing device were recorded. The dosing device was calibrated. Also, during injection into a bucket of water, the behavior of the jet without reagent during immersion was video recorded, as well as the beginning of the reagent supply and the surface of the "melt". A number of treatments were carried out at different gas flow rates and at different intensities of reagent supply. A summary table of the results of the treatments was obtained, which became the basis for further processing of the results of the cold modeling studies. The system of equations for a one-dimensional two-phase steady-state flow is shown. This system includes the equation of state of the gas, the equation for determining the heat transfer between the gas and the pipe wall, the equations for the interfacial force, the attached mass, and the interfacial heat flux. Boundary conditions are formulated based on natural considerations. Using the developed methodology, we calculated the pressure drop, velocities of the gas and solid phases for CaO particles with a diameter of 60 and 100 μm; FeO - 70 and 450 μm; Na2CO3 - 100 μm).

An urgent problem in today's conditions is the improvement of blast furnace process technology. The article emphasizes that an indispensable indicator of progress in the development of blast furnace process technology is the development and improvement of the operation of new loading devices. It is noted that a significant drawback of the operation of these devices is the imperfection of the methods of laying charge components with different densities on the main conveyor to obtain a homogeneous mixture in the hopper. In this case, control of the composition of the mixture of materials when pouring them from the hopper is of particular importance. To study the influence of structural and technological parameters of the BLT operation, a physical model was used on which a study of the mechanism of laying mixtures of different materials in the BLT hopper was conducted. It was established that the ridge consisted mainly of fine particles. The amount of fines in the direction from the ridge to the hopper wall decreases with an increase in the content of the coarse fraction. It is proved that the given nature of the movement of materials in the hopper of this design to the outlet does not depend on the type of materials, their quality, and also on the size of the outlet. With an increase in the size of the outlet opening, the release time decreases, the flow rate increases, and the amplitude of oscillations increases, which indicates an increase in the heterogeneity of both the mass and the granulometric composition of the materials in the flow. The optimal technological parameters are proposed, which prove that the most appropriate is the degree of opening of the charge gate of the BLT, the value of which exceeds by no less than 1.5–2.0 times the degree of opening of the gate, at which the continuity of the flow of materials through the outlet opening is disturbed. It is emphasized that the mechanism of formation of mixtures of charge components in the hopper and their leakage from it must be taken into account when forming a rational method of loading materials into the blast furnace.
