Published: February 2025

The purpose of this work is to study promising areas of sustainable development of ferrous metallurgy of Ukraine in modern conditions. The main areas of stabilization of the industry were considered, including: the influence of the state on the development of the metallurgical industry, problems of improving the range of metallurgical products, scientific development of metallurgical technologies, environmental problems of ferrous metallurgy, problems of scientific support for the development of metallurgical technologies, the main directions of scientific and technical solutions for the sustainable development of metallurgical production. It is shown that currently the main indicators of the country's development are not taken into account in the national state policy - target settings, definition and approval of criteria and parameters of the country's development, publicity and control of their implementation. Such a situation requires the development of an industrial policy in the metallurgical industry. The analysis shows that the problem of the internal market of metal products continues to worsen in the country, the assortment of effective types of metal products is decreasing, the country is increasingly oriented towards the export of raw types of metal products and semi-finished products. It was noted that the scientific and technical support of the metallurgical industry is one of the main factors in the development and efficiency of production. The use of the results of scientific research is one of the main factors in reducing the cost of energy resources for the production of metal products. It was noted that environmental problems can have an extremely negative impact on the prospects for the development of metallurgical production. This situation requires significant investments in the development of scientific research and the creation of new technologies for reducing the carbon footprint during the production of metal products. The analysis shows that due to the use of scientific potential and the use of technologies known in world practice in Ukraine, there is a fundamental opportunity to reduce energy consumption for the production of metal products, improve the environmental situation, and reduce greenhouse gas emissions. Therefore, the issue of scientific and technical support for the innovative development of MMC of Ukraine is extremely relevant today. The primary scientific and technical tasks in this direction are to reduce the consumption of energy resources for the production of metal products and achieve the best global indicators. The main strategic goals and priorities of MMC development at the current stage are shown.

Authors: Konovodov D.V. , Boiarkin V.V. , Boiko M.H. , Ivliev O.M.
Published: February 2025

Low-carbon steel wire takes a large part in the production of wire products. The wire standards regulate the limits of its mechanical properties. Drawing non-uniform strain determines the mechanical properties. One of the main parameters determines the non-uniform strain is the die dimensions, specifically the length of the die bell and the length of the die bearing. Tool manufacturers provide appropriate recommendations for choosing the length of the die bearing depending on the wire diameter. In industry, the die bearing is bored to the required diameter size in worn out dies during previous drawing. Considering the constancy of the die length, this leads to a change in the ratio between the lengths of the die bell and die bearing and to a change in the level of non-uniform strain. The mechanical properties of the wire are determined mainly through the results of experimental investigations, it leads to significant costs of material and energy. In this work, using FEM computer simulation, the influence of the die bearing on the non-uniform strain while drawing 1030 steel wire with a diameter of 1.85 mm was investigated.
ANALYTICAL SUBSTANTIATION OF THE STRUCTURAL PARAMETERS OF THE TECHNICAL CONDITION OF THE FIVE-PLUNGER SUPPORT OF AXIAL-PISTON HYDRAULIC MACHINES
Authors: Melyantsov P.T. , Losikov O.M. , Sidorenko V.K.
Published: February 2025

The purpose of the work was to provide an analytical justification of the structural parameters of the technical condition of the annular support of the five plungers, which could be used to evaluate the further use of the plunger pair in the technological process of repairing the axial-piston hydraulic unit. To achieve it, the first step is to analyze the operating conditions of the fifth plunger of the pumping unit of the hydraulic machine, which is a hydrostatic bearing, which allows to reduce mechanical losses in friction pairs at the expense of some increase in volumetric losses provided for by design solutions. At the same time, it is noted that the change in the structural parameters of the ring support of the heel as a result of hydroabrasive wear leads to an increase in the gap in the friction pair and causes an increase in volume losses of the working fluid. The analytically obtained relationship between the height of the annular support of the heel of the plunger, the gap in the coupling and the pressure of the working fluid relates the change in the height of the annular support to the size of the gap between the annular support of the heel and the support of the cradle for a hydraulic pump or an inclined washer for a hydraulic motor, which indicates the possibility use as a structural parameter to control the ring support of the heel of the plunger its height, subject to uniform wear. To determine the volumetric losses of the working fluid, which are formed by increasing the gap between the ring support of the heel and the support of the cradle, a dependence was analytically obtained. It was determined that the losses of the working fluid between the ring support of the heel and the support of the cradle do not significantly affect the volumetric efficiency of the transmission and can be compensated by the booster pump. The obtained quantitative assessment of the wear of the height of the ring support of the heel can be used to normalize the height of the support during direct diagnostic work when determining the technical condition of the plunger heel.
STUDY OF THE EFFECT OF MODIFICATION WITH HIGHLY DISPERSED SILICON CARBIDE ON THE DENSITY AND MACROSTRUCTURE OF CASTINGS FROM THE SECONDARY ALLOY OF THE AL-SI SYSTEM UNDER DIFFERENT THERMOPHYSICAL SOLIDIFICATION CONDITIONS
Authors: Selivorstov V. , Dotsenko Yu. , Selivorstova T.
Published: February 2025

Presented are the results of research on determining the effect of modification of the secondary aluminum casting alloy of the Al-Si system with highly dispersed silicon carbide of the F1200 brand with a particle size of 1-3 μm in the amount from 0.1 to 0.3 wt.% on the density of the cast metal and the macrostructure of cylindrical castings with a height of 150 mm and with an average diameter of 50 mm, obtained by casting in a metal mold and in a sand-clay mold with the addition of highly dispersed silicon carbide. Studies of the metal density of castings poured into a metal mold and a sand-clay mold, carried out using hydrostatic weighing of samples on analytical balances, showed the presence of the influence of modification and thermophysical conditions of solidification on the relevant indicators. In the metal form, the rate of solidification of the alloy is higher and the structure becomes denser (the alloy density of the castings obtained in the sand-clay mold is 2.7% lower compared to the castings obtained in the metal mold). The alloy with the addition of 0.1% SiC and poured into a metal mold has the highest density. In samples of castings that were cast in a sand-clay mold, with an increase in the amount of SiC, there is almost no significant change in the density of the alloy. The obtained data also indicate that both the method of obtaining castings and modification of the alloy affect its macrostructure. In particular, the macrostructure of the cast secondary alloy of the Al-Si system, which was not subjected to modification and poured into the mold, has a small shrinking sink and scattered porosity throughout the volume of the casting metal and corresponds to the 3rd point on the reference scale. The macrostructure of castings modified with highly dispersed silicon carbide includes a concentrated deep shrinking sink with coarse cracks in the lower part of the shell. As well as concentrated shrinkage porosity in the upper part of the casting. There are no macrodefects in the lower part of the casting. In general, the macrostructure of castings with 0.1-0.3 wt.% SiC, poured into the mold, corresponds to the 2nd and 3rd sparring points on the reference scale. Studies of the macrostructure of castings cast in a sand-clay mold with silicon carbide modification of 0.1% and 0.3 wt.% showed the presence of concentrated shrinking sink in the upper part of the castings and the presence of gas pores on the side surface, which corresponds to the 1st point for reference scale. The analysis also showed that they do not have a pronounced concentrated shrinking sink and all porosity is concentrated on the outside of the casting, while in the upper part of both castings there is a small concentrated porosity.
THE PHENOMENON OF THERMODYNAMIC ACTION DURING PLASTIC DEFORMATION OF METALS AND THEIR ALLOYS
Authors: Kuznetsow E.V.
Published: February 2025

The most important problem of modern technology for mechanical processing of structural materials is to increase the efficiency of shaping operations. Its full value solution requires the establishment of a functional relationship between the parameters of the force influence on the workpiece and the characteristics of the natural adaptive behavior of the processed material. In this regard, using metals and their alloys as an example, the mechanism and general laws of thermodynamic excitation of solid crystalline bodies during plastic deformation are considered. The relationship between the change in the thermodynamic potentials of the substance of the deformed volume and its behavior during the process of shape forming, as well as in the postoperative period, is described. It is shown based on the synergetic method of analyzing highly nonequilibrium systems that from a technological point of view the most favorable adaptive functional response arises in the case when the deforming influence is exerted taking into account the natural ability of the workpiece substance to relaxation. The got results create the basis for improving the operations of mechanical processing of metals and their alloys by taking into consideration the properties and features of the natural deformation behavior of each concrete material under concrete conditions. They are applicable not only for metal forming operations, but also in cutting technology.

En el nombre del planeta. Un análisis desde la teoría política sobre posibles articulaciones del ecologismo
Authors: García-Avalos Ismael
Published: February 2025

La sostenibilidad del planeta ha ido ocupando a escala global las agendas políticas e institucionales durante las últimas décadas. Analizaremos, desde la teoría política, hasta qué punto es correcto entender la preservación del medio ambiente como un asunto puramente científico que pueda ser abordado al margen de la política. A su vez, nos interrogaremos por la capacidad de la política para trascender las ideologías en materias de primer orden como la crisis climática. Posteriormente, analizaremos si es posible concebir al ecologismo como un concepto unívoco o si, por el contrario, nos encontramos ante un significante flotante, un concepto cuyo significado permanece en abierta disputa entre distintas articulaciones políticas que pugnan entre sí por dotarlo de un sentido concreto, armonizándolo con el conjunto de su corpus ideológico. Así, por ejemplo, el ecosocialismo, el Green New Deal, el ambientalismo neoliberal o el ecofascismo serían algunas de las diferentes articulaciones políticas posibles que disputarían en nuestro tiempo el sentido del ecologismo.

Authors: Noviyana Hesti , AB Joko Sutrisno
Published: February 2025

This study aims to examine the effectiveness of the use of LKPD containing Character education based on Group Investigation in mathematics learning in terms of student learning outcomes. The study is a quasi-experimental study with a pretest-posttest control group design. In this design, two groups of students (experimental group and control group) were measured for their learning outcomes on flat shape material, before and after treatment was given. The study population was grade VII students of SMP Negeri 7 Bandar Lampung. Data analysis of the results of this study used the t-test, with analysis prerequisites in the form of normality and homogeneity of variance tests. The results of the normality test with Kolmogorov-Smirnov showed a p value = 0.200 which is greater than 0.05, meaning that the data is normally distributed and the results of the homogeneity test with Levene's Test obtained a p value = 0.711 greater than 0.05, which means that the variance between groups is homogeneous. The results of the independent t-test for the comparison between the experimental group and the control group on the posttest using SPSS showed that the p-value = 0.000 which is smaller than 0.05, meaning that there is a significant difference between the mathematics learning outcomes of students in the experimental group using LKPD containing Character education based on Group Investigation and the control group. The average mathematics learning outcomes of the experimental group were 85, while the control group was only 74. This shows that the use of LKPD containing Character education based on Group Investigation is effective in mathematics learning in terms of students' mathematics learning outcomes on flat shape material.

Learning from the obstacles faced by other universities whose nature is administrative wise, currently questions still arise regarding the implementation of MBKM, which is about how the abilities will be developed by students who take part in the MBKM program, especially their hard skills, Reflective Abstractions. This research aims to determine the Reflective Abstractions (RA) of Students who carry out MBKM program and the factors that cause the obstacles in implementing MBKM. This research used a phenomenology method involving 6 students participating in the MBKM Mathematics Education study program. There was 1 student participating in the MBKM PMM scheme, 4 students participating in the Kampus Mengajar scheme, 1 student participating in the KKN Tematik scheme. The research results were analyzed qualitatively in four steps. This research resulted in all levels of reflective abstractions possessed by MBKM student participants. Starting from level 1, recognition; level 2, representation; level 3, structural abstraction; and level 4, structural awareness. However, not all subjects reach the level 4 of reflective abstractions and not all subjects have consistent reflective abstractions. In certain circumstances, they are facing problems that they have yet to understand from adapting MBKM activities, causing them to be unable to develop the new concepts.
Birdwatchers on social media: The mediatisation of intelligence organisations
Authors: Schrijver Peter , Nietzman Lotte , Pijpers Peter B.M.J.
Published: February 2025

War has always affected the physical and cognitive dimensions of life; however, recent developments in Ukraine and Gaza have increased the emphasis on warfare making use of the virtual realm. Military actions now extend beyond traditional battlefields, significantly impacting virtual and cognitive dimensions through cyberspace and social media. This study examines how intelligence and security services in Ukraine, Israel, and the United Kingdom employ mediatisation—the process whereby mass media shapes public discourse—to achieve their objectives in modern warfare. Through comparative analysis of these three intelligence landscapes, the research explores how these organisations, despite being part of larger national security systems, pursue their own organisational interests. The study reveals that intelligence services use mediatisation for multiple purposes: engaging citizens, justifying operations, and projecting strength to domestic and international audiences. The results show a marked shift from secretive practices to open, public-facing communication strategies. The UK Defence Intelligence provides daily situational updates, the Israel Defence Forces Spokesperson’s Unit releases sensitive intelligence to shape narratives, and Ukrainian military intelligence publishes intercepted communications to undermine adversaries. This selective disclosure via social media represents a significant departure from conventional secrecy, reflecting the growing importance of information warfare. While this approach offers benefits in shaping narratives and countering adversaries, it poses risks to operational security. The study underscores the complex balance that intelligence agencies must strike between transparency and protecting sources and methods in the digital age, highlighting how communication serves as a tool for informing the public, justifying actions and discrediting adversaries.

The competency-based approach (CBA) represents a pedagogical paradigm that prioritizes the acquisition and cultivation of specific competencies over the accumulation of theoretical knowledge. This approach emphasizes the development of crucial skills necessary for students' future professional success and is widely recognized as one of the most efficacious educational methodologies globally. This study aims to examine and evaluate the influence of learning approaches employed in higher education, with a particular focus on the CBA, on student learning outcomes and the cultivation of essential competencies. To accomplish this objective, the researchers employed a quantitative research design, utilizing a structured questionnaire to measure and analyze the impact of the CBA. The survey was administered to 104 students from diverse academic disciplines across Moroccan universities. Data analysis was conducted using the SPSS (Statistical Package for Social Sciences) software, yielding a Cronbach's alpha of 0.77, which is considered acceptable. The findings reveal that the CBA significantly contributes to the development of key skills, including creativity, teamwork, cooperation, communication, and problem-solving abilities in students. Moreover, the study demonstrates a strong alignment of students' academic pursuits and internship experiences with their university education, which is evidenced by the fact that the majority of respondents (54.8% at the Higher School of Education and Training (HSET) and 24% at the Normal Higher School (NHS)) are enrolled in bachelor's degree programs in education. In conclusion, this research underscores the positive impact of competency-based learning approaches on the development of critical skills in higher education students. Furthermore, it highlights the congruence of students' academic trajectories and work placements with their university studies, indicating effective preparation for the demands of the labor market. These findings emphasize the importance of further integrating and promoting the CBA in higher education curricula to ensure a more robust alignment between acquired skills and the needs of the professional sphere.

Patin fish (Pangasius sp.) is a superior commodity that is in demand and widely cultivated by the people of Indonesia. Feed is one of the things that has an impact in fish farming as a growth support. One way to increase feed efficiency is to use additional ingredients, in the form of peat soil humic substances. This study aims to determine the growth response and endurance of catfish seeds (Pangasius sp.) fed with additional humic acid. Feed was given as much as 2% of fish biomass using a completely randomized design (CRD) with five treatments, namely control and humic acid concentrations of 0.25%; 0.5%; 1%; and 2%, for 4 weeks. Each treatment was repeated three times with each replicate containing 10 catfish fry. The results showed that feeding humic acid supplementation with a humic acid concentration of 0.5% had a significant effect on the addition of the mean absolute weight of catfish to 2,394 ± 1,144 with the highest daily growth rate (0.080 ± 0.038 g/day).

Radikalisasi di Indonesia telah menjadi ancaman serius terhadap kestabilan sosial dan keamanan nasional. Pendidikan Islam memiliki peran penting dalam membentuk pola pikir dan karakter generasi muda, sehingga pengintegrasian hadis sebagai pilar deradikalisasi dalam kurikulum pendidikan Islam menjadi sangat relevan. Penelitian ini bertujuan untuk menganalisis peran hadis dalam membentuk kurikulum pendidikan Islam yang efektif untuk mencegah dan melawan paham radikalisme. Metode penelitian ini menggunakan pendekatan kualitatif dengan studi literatur dan analisis dokumen kurikulum yang ada di beberapa lembaga pendidikan Islam. Hasil penelitian menunjukkan bahwa hadis-hadis yang menekankan moderasi, perdamaian, dan toleransi dapat menjadi landasan dalam membentuk materi ajar yang mampu menangkal paham ekstremisme. Selain itu, implementasi hadis ini dapat diperkuat dengan pelatihan guru yang mendalam tentang pemahaman hadis-hadis terkait deradikalisasi. Saran penelitian ini adalah perlunya penyusunan kurikulum berbasis hadis yang lebih komprehensif serta melibatkan para ulama, akademisi, dan pembuat kebijakan dalam mengembangkan strategi pendidikan yang tepat untuk deradikalisasi di Indonesia.

The influence of seasonal factors (autumn and spring) on the leukocyte formula of students during the period of martial law was analyzed. A shift to the lower limit of the norm of lymphocyte indicators and to the upper limit of neutrophil indicators in the autumn period was revealed, which indicates chronic stress caused by martial law and the formation of an adaptive response. In the spring, there is an overstrain of the lymphocyte link and an imbalance in the indicators of the nonspecific link of cellular immunity at the level of monocytes, neutrophils and basophils. The reasons for such an imbalance can be considered the initial chronic stress in the autumn period, increased antigenic load in the winter period, caused by the circulation of SARS-CoV2 and other pathogens of acute respiratory diseases and, as a result, the depletion of adaptive resources of cellular immunity.
