To unveiled the function of exchanging Sm2O3 for B2O3 on the physical and mechanostructural traits of multi-component glass, five distinct type (A, B, C, D and E) of glasses
originated from (50-x)B2O3-10P2O5-30TeO2-10ZnO-xSm2O3 (0.1≤x≤1.5, mol%)
compositions were fabricated by using ordinary approach of melt-quenching. The noncrystallinity status of the synthesized samples was established by X-ray diffraction (XRD)
profile. However, with sequential replacement of B2O3 by Sm2O3, the deduced values of
physical entities such as density (𝑑𝑑𝑠𝑠), Sm3+ ions concentration (𝑁𝑁𝑖𝑖), field strength (F) and
glass hardness (𝐻𝐻𝑉𝑉) of our produced glasses were significantly amplified, while the molar
volume (𝑉𝑉𝑚𝑚) alongside polaron radius (𝑟𝑟𝑝𝑝) and inter-nuclear distance (𝑟𝑟𝑖𝑖) decline. Besides,
data from FTIR with consequential deconvoluted spectral showcased the presence of BO3,
BO4, TeO3, TeO4 and PO4 functional groups which were randomly distributed within the
main glass network.

Authors: Hilal Maulidi , Purnomo Arif , Arief Sandy
Published: November 2024

Indonesia’s legal reform and justice system have long faced challenges of inefficiency, corruption, and a lack of skilled personnel. As the nation strives to modernize and improve governance, a transformative approach is necessary to address systemic shortcomings. This research explores the pivotal role of Human Resources (HR) management in reshaping the Indonesian justice system, arguing that reforms in HR practices are essential to achieving sustainable legal reform and enhancing judicial efficiency. The study introduces a novel perspective by linking HR practices—such as recruitment, training, performance management, and retention—with broader goals of institutional transformation and legal accountability. The urgency of this research lies in Indonesia's ongoing efforts to combat corruption and improve the public sector’s effectiveness. HR reforms are positioned as a key lever for institutional change, offering a pathway to ensure that the judicial system is staffed with competent, ethical, and efficient personnel. The research examines existing HR practices within the justice sector and proposes innovative strategies for talent development, capacity building, and alignment with international standards. By fostering a culture of accountability and professionalism, these reforms can contribute to increased public trust and a more equitable legal environment. This study makes a significant contribution by bridging the gap between HR management and judicial reform in Indonesia. It provides actionable insights for policymakers, legal professionals, and international partners, emphasizing that an investment in human capital is central to achieving a more effective, transparent, and just legal system. Ultimately, the research underscores that HR transformation is not just an administrative reform, but a critical element in the broader pursuit of justice and national development.

Published: November 2024

A technology for thermolytic processing of fuel oil over a tin-lead melt in a flow-type reactor is proposed. Methods for fuel oil processing at oil refineries are currently too complicated and cost-demanding, so the development of effective technologies for fuel oil processing is an urgent task. The main advantages of the proposed technology are rather low process temperature and pressure close to atmospheric. The technological parameters of the process are constant over all points of the reactor, which ensures high-quality products. The formation of carbon deposits on the reactor walls is essentially eliminated. The technological process occurs simultaneously with auxiliary and transport operations, which increases the productivity of the installation. It becomes possible to completely automate technological process, eliminating the use of manual labour and simplifying installation maintenance. A schematic diagram of the flow-type installation is presented. The results of experiments on the thermal cracking of fuel oil over a tin-lead melt, carried out using two versions of destructive distillation, are presented. The first version involves minimal withdrawal of thermal gas oil (31 %), while in the second version it is maximal (77 %). It has been shown that the content of gasoline fraction (i.b.p.-180 °С, where i.b.p. is initial boiling point) and diesel fraction (180-360 °С) in the thermal gas oil obtained according to the second version is lower than that obtained according to the first version. Thermal gas oils have a high content of aromatic compounds, which makes them a promising raw material for the production of needle coke.

Published: November 2024

2-[4-(2-Methacryloyl)-piperazine-1-ylmethyl]-9H-thioxanthen-9-one-S,S-dioxide 1, an electrochemically active monomer, has been synthesised from 2-(piperazine-1-ylmethyl)-9Н-thioxanthen-9-one-S,S-dioxide and methacryloyl chloride. Subsequent radical copolymerisation of the synthesised compound with methyl methacrylate leads to an electroactive copolymer (PMMA-co-ThxSO2) with the ratio of methyl methacrylate fragments in the chain to the pendant (side) groups of the 9Н-thioxanthen-9-one S,S-dioxide structure equal to 95 : 5, respectively. It has been shown by cyclic voltammetry that the electrochemical reduction (ECR) of 1 in acetonitrile (MeCN) is a two-electron and two-stage process, with the formation of long-living radical anion at the first one-electron stage and unstable dianion at the second stage. Electrochemical reduction of PMMA-co-ThxSO2 is due to the reductive electrochemical activity of the pendant groups, and its mechanism is similar to the ECR of monomer 1. This compound is a polymer with pendant groups that play the role of efficient electron traps during charge transport inside the thin copolymer film, and it can be used in the resistive memory technologies (ReRAM - Resistive Random Access Memory) as the active working layer of memristors.
ПОТОМКИ БЕЛОРУССКИХ ПЕРЕСЕЛЕНЦЕВ ПРИТОМЬЯ: КУЛЬТУРА И ИДЕНТИЧНОСТЬ (ПО МАТЕРИАЛАМ ПОЛЕВЫХ ИССЛЕДОВАНИЙ 2022 Г.)
Authors: А.А. РУБЛЕВА
Published: November 2024

Статья посвящена анализу идентичности у потомков белорусских переселенцев Юргинского района Кемеровской области, которая формировалась в условиях трансляции традиций старшим поколением белорусских переселенцев, рожденных в начала XXв., а также в условиях культурных контактов с представителями других восточнославянских групп Притомья. Основным источником исследования стали интервью с потомками белорусских переселенцев (1930-1960-х г.р.). Во второй половине XX в. белорусские переселенцы отмечали традиционные календарные и семейные праздники, сохраняли этнокультурные особенности диалекта, традиционной кухни. Потомков белорусских переселенцев в сельской среде Притомья до сих пор продолжают называть «хахлами». Сами потомки переселенцев этого не отрицают, но считают себя также русскими или сибиряками. Как показал анализ, причинами такой идентичности стали длительное проживание потомков белорусских переселенцев в Сибири и их активные контакты с русскими Притомья.

In the summer of 2022, an ethnographic expedition was conducted in the Yurginsky district of the Kemerovo region. The field research showed that Pritomye is a territory with ethnocultural diversity of population, where in the 20th century in addition to Russian and Ukrainian settlers, Russian indigenous people of Siberia, Mordovians, Germans, and others, there were Belarusian settlers. The aim of this article is to analyze the ethnocultural identity of the descendants of Belarusian settlers in the Pritomye territory. The chronological framework of the study is the second half of the 20th century - the first quarter of the 21st century. The main source of information was the stories of rural residents of Pritomye, whose ancestors were Belarusian settlers. The methodology was based on an ethnocultural approach to understanding identity. The descriptive and comparative-historical method of research was applied. In the second half of the 20th century, the descendants of Belarusian settlers grew up in a cultural environment formed by older generations of Belarusian settlers. They celebrated calendar and family holidays. In their everyday and festive life, Belarusian settlers preserved elements of traditional cuisine and Belarusian dialect. The descendants of Belarusian settlers in Pritomye are still referred to as “khakhly,” a term that is not denied by the Belarusian settlers themselves. Modern descendants of Belarusian settlers, in international communication, consider Siberia their homeland and consider themselves Russians. The reason for such identity is their active cultural contacts with representatives of other ethnocultural groups of Pritomye, in particular with Russian indigenous people of Siberia, and the fact that descendants of Belarusian settlers have been living in Siberia for several generations, which has left an imprint on their culture and identity.
Teologia do domínio
Authors: Xavier Donizete
Published: November 2024

Este artigo explora o conceito da teologia do domínio, questionando se esta deve ser entendida como uma sistematização teológica ou, mais propriamente, como uma problematização de natureza ideológica. Dado que não se trata de uma única teologia, mas de múltiplas abordagens, a teologia do domínio se apresenta como um fenômeno complexo. A análise destaca que essa teologia, em seus diversos desdobramentos, tem contribuído significativamente para a expansão das igrejas neopentecostais e para o fortalecimento das bancadas religiosas cristãs no Brasil, especialmente no âmbito do Poder Legislativo. Esses grupos, frequentemente defensores de um espectro ultraconservador, utilizam argumentos teológicos, morais e escatológicos, muitas vezes influenciados pelo pensamento norte-americano. O artigo visa demonstrar o pano de fundo dessa teologia, ressaltando o risco iminente da projeção de poder baseada na construção de uma imagem.

Objetivo. Validar la aplicabilidad de un método de discriminación de cacaos según su origen geográfico, mediante técnicas de espectroscopía NIR portátil y aprendizaje profundo. Materiales y métodos. Se recolectaron 193 muestras de granos de cacao fermentados y secos de diversas regiones de Costa Rica, utilizando 72 muestras para calibración y 121 para predicción. Las muestras se analizaron para determina su composición proximal, acidez titulable y compuestos fenólicos. Se empleó un espectrofotómetro NIR para recopilar datos espectrales (400-1700 nm). El preprocesamiento de los datos espectrales permitió desarrollar modelos de regresión para predecir características químicas. Para el modelo de clasificación geográfica, se eliminó el ruido de los espectros y se realizó un análisis de conglomerados, usando la distancia Gower y el método de agrupamiento Ward sobre los componentes obtenidos mediante Análisis de Componentes Principales (ACP). Resultados. La grasa fue el principal componente presente en el conjunto de muestras (>39,67%).

Introduction. The production of medicinal plants is a market that has been growing rapidly in recent years and requiressustainable agronomic techniques to meet this demand. The herb spearmint (Mentha spicata L.) is one of these plants in demand worldwide. However, there are not many techniques for its commercial cultivation, whether in terms of harvest, post-harvest, or propagation. As for propagation, this is usually done vegetatively, occasionally with the use rooting agents. Among the wide variety of rooting agents available in the market, the use of algae extracts such as Ascophyllum nodosum is a sustainable alternative. Objective. To evaluate the influence of Ascophyllum nodosum extract on the rooting of spearmint cuttings. Materials and methods. The trial was carried out under greenhouse conditions at National Agricultural University La Molina, Peru with different doses of the extract and different evaluation times. Doses of 0, 1, 5 and 10 mL L-1 of the extract and 3 evaluation moments were used, which were 21, 28 and 35 days after cutting. In this way, an appropriate dose and transplanting time would be obtained. The variables evaluated were root number, root length, rooting percentage, fresh weight of stem, root and leaf, and dry weight of stem, root and leaf. Results. Spearmint cuttings showed significant differences (a = 0.05) for root length, rooting percentage, and root fresh weight with the application of the extract, with better results in the 10 mL L-1 dose for root length and root fresh weight. Conclusion. Ascophyllum nodosum extract proved to be efficient in rooting Mentha spicata cuttings.

In their study, Stavropoulos et al. (2023) capitalized on supervised machine learning and a longitudinal design and reported that the User-Avatar Bond could be accurately employed to detect Gaming Disorder (GD) risk in a community sample of gamers. The authors suggested that the User-Avatar Bond is a “digital phenotype” that could be used as a diagnostic indicator for GD risk. In this commentary, our objectives are twofold: (1) to underscore the conceptual challenges of employing User-Avatar Bond for conceptualizing and diagnosing GD risk, and (2) to expound upon what we perceive as a misguided application of supervised machine learning techniques by the authors from a methodological standpoint.

Role of bile acids in atherogenesis: review
Authors: Safaryan A. S.
Published: November 2024

The review describes the metabolism of bile acids (BAs) in the human body, their effect on cholesterol metabolism and the development of atherosclerosis, which remains one of the most pressing problems in medicine. The problem of cholestasis is discussed, which is often found in patients with cardiovascular diseases with comorbidities, including non-alcoholic fatty liver disease and which plays a key role in the development of many complications associated with impaired BA metabolism, including hyperlipidemia, metabolic syndrome. Cholestasis treatment, which allows restoring normal cholesterol levels, are considered. Timely administration of ursodeoxycholic acid makes it possible to prevent atherosclerosis (primary prevention of atherosclerosis), because with normal bile metabolism, the levels of proatherogenic lipids are normalized and the production of inflammatory mediators, high levels of which contribute to atherogenesis, decreases. In this review, the author presents the important role of bile metabolism in the primary and secondary prevention of atherosclerosis and the possibility of solving this issue by prescribing ursodeoxycholic acid and changing lifestyle.

Published: November 2024

Data are accumulating on the direct influence of psychoemotional and psychosocial factors on the inexorable growth of obesity prevalence, and therefore the concept of an interdisciplinary approach is needed, including dietary, physical activity and mental state modifications.

Aim. To determine the effectiveness of cognitive-behavioral group the­ra­py (CBGT) in combination with nutritional modifications for body mass (BM) management in women with obesity.

Material and methods. The study involved 20 women (mean age 46,6±12,3 years) with a BMI ≥30 kg/m2, rigid to diet therapy. A medical psychologist and a nutritionist conducted CBGT sessions with the participants. Initially, BM, BM index, and eating behavior were assessed (DEBQ, Stunkard, CARDIA questionnaires). In addition, the following were used to study the mental status: Toronto Alexithymia Scale ­(TAS-20), vital exhaustion test, University of California, Los Angeles (UCLA) Loneliness Scale, Test of Self-Conscious Affect (TOSCA), Reeder Stress Inventory, and Psychological Stress Measure (PSM-25). The changes were studied 8 weeks after the start CBGT.

Results. After 2 months, the BMI dynamics was -4,33 kg (p<0,001). A decrease in the severity of emotional eating behavior by an average of 0,77 (p<0,001), external eating behavior by 1,05 (p<0,001) points was noted, no significant changes in restrained eating behavior were obtained (p=0,43). According to the CARDIA test, after 2 months of CBGT, the detection rate of pathological significance of BM decreased by 50% (p<0,001); as well as episodes of loss of control over food intake (initially in 5 (25%) (p<0,001)), distress due to loss of control over food intake (initially in 6 (30%) (p<0,001). CBGT in combination with dietary intervention showed a decrease in the severity of chronic stress, which corresponded to an increase in the total score from 1,8±0,75 to 2,0±0,60 (p<0,05), a decrease in vital exhaustion from 5,6±3,89 to 4,1±2,66 (p=0,001) and loneliness from 34,9±12,61 to 29,9±7,57 (p=0,007), a decrease in guilt-proneness from 53,0±8,42 to 42,8±11,18 (p<0,001) and shame-proneness from 38,3±10,99 to 31,6±10,07 points (p=0,014).

Conclusion. The mental state of a person has a significant impact on eating behavior and on the regulation of BM, which emphasizes the need for complex interventions to provide effective assistance to people with obesity.

CircCNKSR2 Facilitates NSCLC Tumorigenesis and Warburg Effect via miRNA-138-5p/PLEK2 Axis
Authors: Ding Dongxiao , Shi Ke , Ying Junjie , Shang Wenjun , Du Chengli
Published: November 2024

Non-small cell lung cancer (NSCLC) has a high global incidence and mortality rate. Although circRNAs have significant attention in tumor research, it's role in NSCLC is uncertain. QRT-PCR and Western blotting were utilized to quantify the expression of circCNKSR2, miR-138-5p, and PLEK2 in NSCLC tissues and cells. The characteristics and subcellular localization of circCNKSR2 were determined using RNase R analysis and qRT-PCR. In vitro functional experiments determined the biological functions of circCNKSR2. The specific binding interactions among circCNKSR2, miR-138-5p, and PLEK2 were evaluated through bioinformatics analysis, luciferase reporter, and rescue assays. In vivo xenograft model was established to examine the impact of circCNKSR2, which was significantly increased in NSCLC tissues and cells. Functional studies demonstrated that silencing circCNKSR2 significantly inhibited NSCLC malignant phenotype and Warburg effect. Bioinformatics analysis and rescue experiments verification indicated circCNKSR2 functioned as a miR-138-5p sponge, and inhibiting miR-138-5p reversed the suppressive effect of silencing circCNKSR2 in NSCLC. Additionally, PLEK2 identified as a miR-138-5p target gene. The potential regulatory role of circCNKSR2 in NSCLC progression and Warburg effect via the miR-138-5p/PLEK2 pathway was demonstrated.
The issue of the admissibility of conducting municipal management by local government units in the form of commercial companies in and outside the sphere of public utility – legal assumptions
Authors: Wojtkowiak Anna
Published: November 2024

According to art. 2 of the Act on Municipal Economy, municipal economy may be run by local government units in the form of commercial law companies. While the application of capital companies to the conduct of municipal management in the sphere and beyond the public utility sphere by local government units is beyond doubt. The situation is different in the case of municipal management in the public utility sphere by partnerships. The Municipal Economy Act does not provide a clear answer to the question whether local government units may establish commercial partnerships in order to perform public tasks in the sphere of public utility. The analysis of the provisions and their linguistic, teleological and systemic interpretation may lead to different conclusions, which is reflected in the different views of the doctrine on this subject.
Genesis and effects of the activities of the Branch of Poznań University of Physical Education in Gorzów Wielkopolski from 1971 to 1984
Authors: Jurek Tomasz , Pilecka Dorota
Published: November 2024

The purpose of the article is to present the 13-year-long activity of the Gorzow branch of the Academy of Physical Education. The article was prepared in accordance with the methodology of historical research. It is based on the analysis of archival materials, documents and files. The branch of the Higher School of Physical Education in Poznań (since 1973 known under the name of the Academy of Physical Education) was established in 1971, in the Gorzow district as a result of the efforts of local and provincial authorities. Initially, the new educational institution functioned as the Branch (1971–1984). The period of 1971–1984 was the most difficult and least known in the fifty-year history of the university. Many teachers commuted from Poznań, and the teaching base was modest. From 1971 to 1984, the Gorzow school educated full-time and part-time students. During the period under review, a total of 1,400 graduates completed their master’s degrees. Significant contributions to the development of the university were made by: associate professor Lech Erdmann (1972–1974), associate professor Tadeusz Łobożewicz (1974–1976), Professor Jerzy Gaj (1976–1984). The rector, Prof. Stefan Bączyk, and his successors Prof. Zbigniew Drozdowski and Prof. Alexander Kabsch were also meritorious. In 1982, under martial law, an unexpected, unsuccessful attempt was made to make the Branch independent andt ransform it into an independent university.
Ido as treatment, healing or self-healing. About the relationship between traditional East Asian martial arts and medicine
Authors: Cynarski Wojciech J.
Published: November 2024

Ido, in the sense of “medicine of martial arts”(bujutsu idō), is analyzed from the perspective of the General Theory of Fighting Arts in many aspects. In particular, the social reception of this and related forms of natural medicine is interesting, which is the main topic of reflection here. The terms “health” and “human” are understood here holistically. Social reception is analyzed here indirectly, through the presence in opinion-forming weeklies and other periodicals. Selected magazines from the years 1982–2023 and direct interviews with three experts constitute the sources. There are also two more qualitative methods, i.e. long-term participant observation and analysis of the content of the literature on the subject. A set of healing or self-healing methods was characterized and a general picture of alternative medicine in mass culture was shown, based on the content published in various magazines. Sharp criticism is mixed here with interest reflected in the search for non-pharmacological methods of therapy. The diverse image of alternative medicine (natural, holistic) in mass culture is shaped by the media. It is rare to associate traditional martial arts with natural medicine.
Self-Reported Physical Activity and Aerobic Endurance Among Female Students of Pavol Jozef Šafárik University in Košice, Slovakia
Authors: Horbacz Agata , Majherova Maria , Melichar Richard , Junger Jan
Published: November 2024

One of the easiest ways to improve everyone’s physical and mental health is to choose appropriate physical activity (PA). Its general decline in recent decades has triggered an increase in civilisation-related diseases. Female college students neglect PA more than males. We compared the PA of female undergraduates at the University of P.J. Šafárik in Košice (UPJŠ) to their actual aerobic endurance based on our research. The study comprised 268 female students from four UPJŠ faculties. PA data were gathered using a short version of the International Physical Activity Questionnaire (IPAQ). Aerobic endurance capacity was determined using the results of a 20m beep-test, which was then converted to estimated VO2 max values. The results were comparable to other studies when converted to MET-min/week, but undergraduate students’ self-reported PA did not differ between faculties. A correlation exists between total (r = 0.24; p <0.05) and vigorous (r = 0.34; p <0.05) PA and 20m beep-test aerobic endurance. The level of PA among female UPJŠ students is in line with that observed in other studies following pandemic prevention measures. However, its lower intensity may affect aerobic performance. Future goals include increasing female students’ interest in moderate-and high-intensity PA to improve aerobic endurance and health.

The increasing number of individuals who lack religious faith or self-identify as nonreligious in certain parts of the world necessitates a shift in the science–religion dialogue and a change of some key categories and notions. This shift, I argue, implies the expansion of the science–religion dialogue into a science–worldview dialogue, so the core question becomes the relevance of science for the formation, revision, and rejection of both religious worldviews (such as Buddhism, Christianity, and Islam) and secular worldviews (such as scientific naturalism, liberal naturalism, and secular humanism). I begin by explaining what worldview studies are and why refocusing from science and religions to science and worldviews is important. I then identify the main ways of relating science and worldviews in a new typology and provide examples for each.
Regulating Artificial Intelligence to Advance Financial Inclusion in South Africa
Authors: Mota Makore Shelton Tapiwa
Published: November 2024

The emergency of Artificial Intelligence (AI) endowed with capabilities to simulate human intelligence through software-coded operations, has become a topical issue perplexing the minds of regulators, government officials, non-governmental organisations, and the public, across the globe. Linked to this increasing AI debate, is the view that these technologies have the potential to facilitate financial inclusion. Whilst there are concomitant liability and cyber-security related issues associated with AI adoption, the importance of AI in facilitating financial inclusion cannot be overstated. AI can facilitate financial inclusion by enhancing the quality of financial services products and services offered by key players in the South African financial sector, including the capacity to improve the process of opening bank accounts, data analysis, assessment of credit scores, and the management of risk-linked to various financial products. Drawing significant lessons from a select study of the EU and UK model on the regulation of AI, this article argues that there is a need for South Africa to develop an effective regulatory framework governing AI in pursuit of advancing the goals of financial inclusion, among other things.  In finality, the article offers pertinent recommendations in search of avenues for developing policies, principles, norms, and rules that govern AI in South Africa to advance financial inclusion and other important related goals.
A Case for the Right to Education for Stateless and Undocumented Children: A South African Analysis in the Light of International Law
Authors: Mahleza Yeukai , Maake-Malatji Mahlatse I
Published: November 2024

This paper is grounded in the right to education, guaranteed to every child, whether stateless or undocumented. Being stateless means that the child is not considered to be a national by any State under the operation of its law and when a child is undocumented it means that they have no government-issued proof of identity. The Constitution of the Republic of South Africa, 1996 provides the right to education for all children, regardless of their nationality. However, whether stateless or undocumented, they encounter impediments when they attempt to exercise their right to education. The study questions whether the South African Government is complying with its constitutional and international legal obligations to provide the right to education to all children. The paper contends that it is not sufficient to state that every child has the right to education, and that there is a need to formulate guidelines and procedures to be followed in cases where children are undocumented or stateless. In addition, the paper analyses the relevant education laws and policies together with the immigration laws and the effects they have on one another. It further addresses how the provisions of immigration law related to education impede undocumented and stateless children from accessing the right to education. Accordingly, the study identifies the gaps in the laws regulating the right to education and their implications when stateless and undocumented children seek to exercise the right to education. This paper recommends that the South African Government adapts its education laws and procedures in ways that consider the circumstances of stateless and undocumented children.
Development of a physical separation pre-concentration process for the extraction of Rare Earth bearing ore

Published: November 2024

This paper investigated the pre-concentration amenability of sovite (carbonatite) ore to enhance the grade of rare earth elements (REE) bearing minerals by rejecting calcite, and to improve total rare earth elements (TREE) recovery using gravity and magnetic separation. A high proportion of calcite affects downstream processes like leaching due to high acid consumption. Multiple flowsheets combining gravity and magnetic separation were employed to target > 60% TREEs recovery to the final concentrate and > 60% calcite rejection to the tailings. Head analysis of the feed showed the sample's main constituents as Fe (15.61%), Ca (16.04%), SiO2 (7.13%), and lastly TREEs (1.12%). Mineralogy liberation data at 2mm top size indicated poor liberation of TREEs, with the majority of minerals displaying < 30% mass greater than 80% liberated. Grain size distribution data showed that the majority of REE minerals are fine grained and report to the < 20 μm size class. Calcite liberation mineralogy showed < 60% mass greater than 80% liberation.A combination of a single-stage shaking table with a wet high intensity magnetic separator at a magnetic intensity of 7520 G was found to be the optimum flowsheet. For a shaking table feed with P80 of 150 μm followed by tails regrind to P80 of 45 μm as feed to wet high intensity magnetic separator, the overall mass balance results showed that 60.5% TREEs are recovered to the concentrate while 63.0% calcite is rejected to the tails. However, due to the fine-grained nature of TREEs, no flowsheet improved their grade.

Let us recall some classes of rings. A ring R is said to be k-nil-clean if each element can be written as a sum of a nilpotent and k idempotents. A ring R is said to be fine if each non-zero element can be written as a sum of a unit and a nilpotent. A ring R is called nil-good if every element is a nilpotent or a sum of a nilpotent and a unit. And, finally, ring R is called nil-good clean if every element is a sum of a nilpotent, an idempotent, and a unit. In this paper, we continue our work on additive problems in formal matrix rings over residue class rings. We have found necessary and sufficient conditions for the nilpotency of a formal matrix over residue class rings. After that we have shown that a ring of such matrices is (p –1)-nil-clean and nil-good clean. Also, answering the question posed in the previous article of the second co-author, we prove that a ring of formal matrices over residue rings is never nil-good, and, therefore, not fine.

It is traditionally believed that theories and formulas for averaging (homogenization) the physical properties of dispersion media, which exclude the effect of the collective interaction of dispersed particles, are applicable only at low concentrations of the dispersed phase. This opinion was disapproved theoretically and then experimentally in a previous paper. It has been established that with an increase in the concentration of dispersed particles, the main effect on the change in the effective thermal conductivity coefficient of the dispersion medium is exerted by the purely geometric factor of compaction of dispersed particles. Therefore, if the experimental conditions correspond to the theoretical premises considering a two-phase medium as homogeneous and isotropic and the dispersed particles as isolated from each other, then Maxwell's analytical formula is applicable (with an error of less than 2.7%) over the entire range of variation of concentrations and phase parameters. It is shown that the proposed new analytical dependence, which is invariant with respect to the phase inversion transformation and does not take into account the interaction of particles, best describes experiments in binary metal mixtures when it is impossible to isolate a continuous dispersed phase.

By the end of the 20th century, the development of information technologies and globalization led to significant changes in the economy, stimulating the emergence of innovative processes. The growing role of scientific knowledge and information as factors of economic development became central in the concepts describing the innovative activities of this period. The article analyzes various concepts of innovations of domestic and foreign authors, including S.Yu. Glazyev, N.I. Ivanova, L.M. Gokhberg, E. Rogers, M. Porter, R. Henderson, K. Clark, G. Chesbrough, C. Christensen, D. Brown, M. Rutt, D. Tiss, A. Schlesinger Jr., G. Itskovich, L. Leydesdorff, S. Konvez, F. Stewart, R. Ayres, K. Fukuda, and K. Watanabe. The article explores the concept of technological paradigms, national innovation systems, the theory of diffusion of innovations, the model of open innovations, the ecosystem and other approaches to innovative activities. The author systematizes and summarizes the ideas of various authors to identify key aspects and trends of innovative processes in the economy.
Twenty‐First Century Autocrats and Their Followers: A Comparative Inquiry
Authors: Helms Ludger
Published: November 2024

Leadership and followership have long been considered to be defining features of democratic politics. However, more recently, both conceptual redefinitions and real-world developments have put issues of leadership and followership in regimes from beyond the family of established liberal democracies center-stage. This article looks into the nature of authoritarian leadership and followership from a comparative perspective and in light of theories of democratic political leadership. As the inquiry suggests, the rise and nature of leadership activities in contemporary authoritarian regimes reflects both the turn towards more competitive types of autocracy and the aspiration of many authoritarian powerholders to be seen as democratic. At the same time, some of the most spectacular manifestations of autocratic leadership relate to democratic rather than established authoritarian regimes. While followers of autocratic leaders can control their leaders only to the extent that a regime provides mechanisms of vertical accountability, authoritarian followers, even in established autocracies, are not in all regards less important or powerful than their democratic counterparts. Many authoritarian followers do not just support autocrats, but actively attack and chase non-followers or followers of other leaders, and thus play an independent role in the legitimation or de-legitimation of leaders and regimes.

The purpose of the article is to trace the coverage of events in Ukraine by the French edition of Le Monde during Russia’s full-scale invasion. To achieve this goal, the following tasks have been set: to analyse the attitude of the French media to Russia’s armed aggression on the territory of Ukraine; to determine the number of Le Monde publications devoted to the war in Ukraine; to find out the problematic and thematic aspect of Le Monde’s materials covering the image of Ukraine.

The method of analysing the scientific literature was used to determine the views of Ukrainian scholars on the problem of objective and accurate media coverage. The method of media monitoring helped to identify Le Monde publications (41 in total) that covered Ukrainian issues. The content analysis method identified the topics of the relevant publications and the presence of Russian propaganda narratives in them.

We analysed 41 publications covering various areas of Ukrainian and international realities in the context of the Russian-Ukrainian war. In February-April 2022, publications on military (50%), economic (25%) and socio-political (25%) topics prevailed. In February-April 2023, the trends in the coverage of topical issues related to Ukraine changed somewhat, which affected the distribution of the number of stories on different topics: military (60%), economic (30%), and socio-political (10%).

Analysing the way Le Monde covers Ukraine, it can be concluded that this newspaper treats Ukrainian events with great attention and objectivity. By offering its readers a thorough and objective analysis of the circumstances of the Russian-Ukrainian war, Le Monde plays an important role in shaping the image of Ukraine in the international arena.
Historia Constitucional de las restricciones a los derechos políticos de los militares y policías en Colombia, 1886-1991
Authors: Cajas Sarria Mario Alberto
Published: November 2024

La Constitución Política de Colombia les prohíbe a los miembros de la Fuerza Pública participar en política, deliberar y votar. Estas restricciones a los derechos políticos tienen una rica  trayectoria política y jurídica. Con base en fuentes  primarias y secundarias, este artículo narra la historia de esas limitaciones constitucionales y legales, y las sitúa en los distintos contextos políticos en los que surgieron entre las Constituciones de 1886 y  1991. La reconstrucción permite apreciar cómo dos asambleas constitucionales, el Congreso, el Ejecutivo, la Corte Suprema de Justicia, e incluso los propios militares, contribuyeron en el diseño de dichas limitaciones. De igual modo, revela cómo las prohibiciones están ligadas a preocupaciones históricas sobre el papel de la Fuerza Pública en las elecciones y la política.
