At present, the use of standard technical and economic indicators of a mining enterprise to account for the operation and repair of BelAZ heavy-duty mining dump trucks does not provide a complete understanding of the reasons for the failure of these machines and all mining equipment. This makes it difficult to determine the initial causes of failures and the conditions for their occurrence, which in turn hinders the development of more effective maintenance and repair strategies for BelAZ dump trucks. To solve this problem, it is necessary to use formulas for calculating reliability indicators, such as the Stegers formula and the mathematical expectation of time to failure. To solve this problem, it is necessary to use formulas for calculating reliability indicators, such as the Stegers formula and the mathematical expectation of time to failure. These methods allow you to more accurately determine the likelihood of failures and identify the most likely causes of its occurrence. Thus, they contribute to a more effective management of the risks of equipment failure and increase the reliability of the system for the use of BelAZ heavy mining dump trucks and their repair. However, the use of formulas for calculating reliability indicators requires a higher qualification of employees of a mining enterprise, additional knowledge and skills in the field of mechanical engineering, mathematics and statistics. In general, the use of technical and economic indicators in combination with formulas for calculating reliability indicators is an important tool for improving the efficiency and reliability of the system for using BelAZ dump trucks and their repair at a mining enterprise. However, in order to achieve maximum efficiency of equipment operation, it is necessary to take into account all possible factors that affect the process of operation and repair of BelAZ heavy-duty mining dump trucks, as well as constantly improve risk management methods and tools.

Self-excited oscillations remain a frequent problem of cold rolling of thin strips. When self-oscillations occur, the amplitude increases by a jump of more than a hundred times, that is from 2–3 m/s2 to 200–250 m/s2. Oscillation frequencies (from 100 to 500 Hz, i.e. the number of loading cycles) can reach several thousands per a few seconds. Intense self-oscillations normally occur on thin strips with a thickness of less than 1 mm and high rolling speeds. The control of the occurrence of self-oscillations includes special systems, according to the level of vibrations or technological parameters, for example, by fluctuations in the tension of the strip. In control systems, classical methods include the decomposition of the controlled signal into a Fourier series. For stationary processes, Fourier series decomposition provides complete information about the signal structure and is sufficient to diagnose the technical condition of machines and mechanisms. As for a nonstationary non-harmonic signal, the information about the spectral composition of the diagnostic signal is insufficient, since it does not allow for determining the moment of occurrence of an undesirable process. In metallurgy and rolling production, processes are frequently not stationary. The cold rolling process is continuous, but discrete. It takes 5–6 minutes to roll one coil. The process of selfoscillation, even when using control systems, can last no more than 2–3 seconds. A high frequency of vibrations and a high level of stress can lead to the formation of cracks in the elements of the mill stands, for example, CVC plates. A signal conversion wavelet can become an alternative way of monitoring and diagnostics. If the FFT allows you to determine the presence of self-oscillations only in the developed state, the wavelet transform allows you to determine the origin of the selfoscillation process at low oscillation amplitudes. It also allows you to determine it in the absence of fluctuations by changing the signal of the technological parameters.
Social media – Boon or Bane?
Authors: Burooj Ahmed
Published: July 2024

Introduction and aims

This literature review examines the complex relationship between social media usage and its subsequent health sequelae while shedding light on fields of research that require further investigation in accordance with PRISMA guidelines.

Materials and methods

Indexing services (SCOPUS and PUBMED) were used to identify pertinent studies, prioritising original research, review articles, and meta-analyses from 2018 to 2024. Papers not published in English (or where full-text translation was not available), research conducted solely on non-human populations, and proposal and opinion papers were excluded. Papers from before 2018 and those that observed an effect in a sample size of 50 participants or less were also omitted. The author then conducted a thorough evaluation of each study to ensure relevance and significance. After deduplication of results and implementation of the exclusion criterion, a total of 50 papers were shortlisted for this review. The keywords used for this literature search were “social media,” “internet usage,” “health,” “depression,” “cyberbullying,” “addiction,” and “misinformation.”

Results

The findings reveal a complex interplay between social media usage and psychosocial well-being. Social media facilitates global connectivity but correlates with depression, anxiety, and suicidal ideation, especially among adolescents. Cyberbullying, anonymity-driven, escalates mental health risks. Social media usage links with addictive behaviours, substance abuse, misinformation propagation, and racial discrimination, exacerbating public health crises.

Conclusion

Longitudinal studies are crucial to understand causal relationships and develop targeted interventions. Collaboration among stakeholders is imperative to promote responsible social media usage and protect public health in the digital age.

VARIEDADE DA SÁTIRA: UMA ANÁLISE DE CARTAS DE UM DIABO A SEU APRENDIZ, DE C. S. LEWIS
Authors: Scutari Pâmela Rodrigues
Published: July 2024

A sátira como obra literária e diversa formal e estilisticamente, e como meio de agressão, denúncia, crítica e correção de sua vítima se manifesta desde a antiguidade. A função social desempenhada pelo satirista ao apresentar a verdade, isto é, discrepâncias entre ideal e realidade, gera temor em seu público e se associa a uma tarefa moral. Isso revela a proximidade da sátira à religião, já que o comportamento lhes é um elemento em comum: a primeira denuncia, humorada e/ou agressivamente, a hipocrisia de determinado grupo social para lhe sugerir correção; a última prescreve comportamentos que considere adequados à sociedade religiosa, porém oferece exemplos de hipocrisia ao longo de sua história. A ficção epistolar Cartas de um diabo a seu aprendiz (1942), de C. S. Lewis, demonstra, portanto, a manutenção da variedade formal, estilística e, principalmente, funcional da sátira ainda no século 20, e a relação dialética entre satirista, obra literária e os contextos histórico-social e religioso em que se insere.

EXPERT-ANALYTICAL PRODUCT: APPROACHES TO FORMATION AND IMPLEMENTATION IN THE COMMUNICATION ENVIRONMENT OF POLITICAL SECURITY
Authors: TRETIAK Oleksii
Published: July 2024

The article is devoted to the unification of approaches to the analysis of the public information environment, as well as the coordination of efforts to counter information aggression on a decentralized basis. The purpose of the study is to establish the main features and principles of the formation of an expert-analytical product within the framework of strengthening the security capacity of Ukrainian society. The value of a quick asymmetric information response in the form of discrediting the source, disavowing the information provided and/or using errors or mistakes in the information provided to one’s advantage is characterized. It was emphasized that the targeting of political and security content should also take into account the socio-demographic and behavioral characteristics (data) of the community to which the information is directed. The creativity of the expert-analytical security product is analyzed, which means a creative approach to counter hostile informational provocations and invasions. The importance of the principle of responsiveness, which means the compliance of the appearance of content with time dimensions and the requirements of the political and security situation, is revealed. It was found that the appearance of expert political and security materials should precede the events, be carried out according to the plan of media events, as well as within the framework of crisis situations. It was revealed that the empirical nature of the expert-analytical product involves the use of various models for assessing threats to political security. It is proven that the development of various scenarios of expert public content contributes to the development of the political situation in the future in the desired direction. It has been established that the expert-analytical product of public direction (reports, assessments, analytical summaries, etc.) should not only be broadcast in an accessible (understandable) language. It is assumed that the complexity and completeness of information means its completeness in terms of known and unknown facts. It has been established that the value neutrality of communication messages means avoiding the promotion of ideological messages and motivational components, except when such materials are not included in special promotions and operations. It was found that open discussion leaves the possibility of the information consumer to interactively interact with the text of the message and data. It was concluded that a promising direction of information security activity is asymmetric action in relation to operational massive support of political actions of hostile power institutions on the international arena.

Authors: Khorolskyi M.S.
Published: July 2024

Майбутній розвиток економіки України залежить від темпів зростання валового продукту порівняно з досягнутим рівнем і постійно залежить від науково-технічного прогресу, який повинен забезпечувати вказане зростання. Для цього нашому поколінню належить передати молоді – здобувачам освіти, майбутнім творцям наукоємних об’єктів ті знання, досвід і навички, які вже досягнуті, і закласти фундамент подальшого розвитку, творчого підходу для появи та реалізації нових ідей, створення надійних нових перспективних об’єктів і технологій, розробки нових конструкційних матеріалів з більш високими технічними властивостями, які і є джерелом їх створення. Здобувачі освіти отримують знання переважно від викладачів, з підручників, наукових статей, з інтернету тощо, оскільки свого практичного досвіду поки що не достатньо. Але у зазначених мною в даній статті деяких джерелах інформації має місце, на мій погляд, не коректна та помилкова технічна термінологія, на яку повинні звертати увагу здобувачі освіти і викладачі та забезпечувати чистоту української мови. Аналізуючи різну термінологію, здобувачі освіти будуть розвивати і свою творчість уже сьогодні і розвивати та удосконалювати свої знання. Наприклад, в різних джерелах інформації можна прочитати, що конструкційні матеріали мають експлуатаційні властивості, яких, на думку автора, у них немає, а є лише технічні властивості, які сильно впливають на експлуатаційні властивості виготовлених із них виробів за відповідною конструкторською і технологічною документацією. Розробляючи той, чи інший конструкційний матеріал, потрібно зразу опрацьовувати технологію його виготовлення, вивчати, які у нього переваги перед існуючими та які недоліки. Це прискорить його впровадження у виробництво. У статті також наведені найбільш типові широко вживані технічні терміни з зазначенням правильної термінології відповідно до стандартизованих термінів або з зазначенням їх сталого використання, а також помилкові терміни, які не мають технічного обгрунтування. В статті акцентується увага на тому, що правильна термінологія - це один із основних напрямків надання якісних знань здобувачам освіти.

Multifiller carbon nanotube, graphene, and carbon black composite filaments: A path to versatile electromaterials
Authors: Lepak-Kuc Sandra , Nowicki Łukasz , Lekawa-Raus Agnieszka , Jakubowska Malgorzata
Published: July 2024

Addressing the growing demand for conductive and flexible composites, this research focuses on producing thermoplastic composite fibers made of polyurethane and carbon nanomaterials featuring the highest possible electrical conductivity. Based on a recently developed methodology enabling the formation of very high filler contents of 40% w/w, this work presents a systematic investigation of the role of all the materials used during the manufacturing process and selects the materials that ensure the best electrical performance. The results show that the highest electrical conductivity and current-carrying capacities are obtained when dimethylformamide is used as a solvent, and small amounts of AKM surfactant aid the de-agglomeration of carbon nanomaterials. It is also shown that the hybridization of MWCNTs filler with graphene nanoplatelets and small amounts of carbon black is beneficial for the electrical properties. However, the highest performance is achieved with SWCNTs as fillers, exhibiting two orders of magnitude higher electrical conductivities of 6.17 × 104 S/m.

Impact statement

The article presents a pioneering exploration into the synthesis and application of a novel composite material. This research significantly impacts the field of electromaterials by introducing a cutting-edge approach that leverages the synergistic properties of carbon nanotubes, graphene, and carbon black within a single filament. The impact of this research extends beyond the laboratory, influencing the development of next-generation materials that bridge the gap between conventional materials and advanced nanomaterials. The presented composite filaments open avenues for the creation of innovative devices and systems that demand good mechanical strength, electrical conductivity, and thermal stability. Moreover, the versatility of these filaments allows for the optimization of materials properties, enabling customization based on specific application requirements. In addition to its technological significance, the paper contributes to sustainability efforts by facilitating the production of lightweight, energy-efficient materials. The insights provided by this research have the potential to reshape the landscape of materials science, inspiring further exploration and innovation in the quest for versatile and high-performance electromaterials.

Frequency response sensitivity to crack for piezoelectric FGM beam subjected to moving load
Authors: Huyen Nguyen Ngoc , Huan Duong Thanh
Published: July 2024

Since functionally graded material (FGM) is increasingly used in high-tech engineering, free and forced vibrations of FGM structures become an important issue. This report addresses the analysis of frequency response sensitivity to crack for piezoelectric FGM beams subjected to moving load. First, a frequency domain model of a cracked FGM beam with a piezoelectric layer is conducted to derive an explicit expression of the electrical charge produced in the piezoelectric layer under the moving load. It was shown in the previous works of the authors that the electrical charge is a reliable representation of the beam frequency response to moving load and can be efficiently employed as a measured diagnostic signal for structural health monitoring. Then, a damage indicator acknowledged as a spectral damage index (SDI) calculated from the electrical frequency response is introduced and used for sensitivity analysis of the response to crack. Under the sensitivity analysis the effect also of FGM and moving load parameters on the sensitivity is examined and illustrated by numerical results.

The Relationship Between Current Account Deficit and CBRT Policy Rates After the 2008 Crisis: ARDL and NARDL Bounds Test Approach
Authors: Sümer Ayşegül Ladin , Peker Osman
Published: July 2024

The current account deficit continues to be a constant problem due to the structural problems of the Turkish economy and the tight monetary policy implemented after the 2008 crisis. Therefore, the measures taken against the current account deficit constitute the priority agenda items of the CBRT. This study aims to comparatively examine the relationship between the current account deficit and the policy interest rate in the inflation targeting and floating exchange rate system using ARDL and NARDL bounds test methods in the period 2011:Q1-2023:Q1. Cointegration test results confirm the existence of a long-run relationship between the variables. ARDL model long-run and short-run coefficients show that the policy rate does not have a significant effect on the current account deficit. NARDL model long-run and short-run coefficients prove that the policy rate does not have a significant and asymmetric effect on the current account deficit. The findings indicate that the expected impact of policy interest rate adjustments on the current account deficit is limited. As a result, it is concluded that the reaction of the exchange rate to the policy interest in inflation targeting will be more decisive in keeping the current account deficit at a sustainable level.
Challenges with measures used for assessing research impact in higher education institutions
Authors: Mfengu Andiswa , Raju Jaya
Published: July 2024

Internationally, there has been a push for the prioritisation of research impact beyond its scholarly contribution. Traditionally, research impact assessments have focused on academic impact and quantitative measures, at the expense of researchers for whom research impact cannot be quantified. Bibliometric indicators and other quantitative measures are still the most widely used method for evaluating research impact because these measures are easy to use and provide a quick solution for evaluators. Conversely, metric indicators fail to capture important dimensions of high-quality research. Hence, in this study, we explored challenges with metric indicators. We adopted a case study of the University of Cape Town and used document analysis, a questionnaire survey to collect data from academics and researchers, as well as semi-structured interviews with a sample of academic and research staff. The findings highlight common challenges with quantitative measures, such as bias and discipline coverage, and the ability of measures to drive researchers’ behaviour in another direction. We propose the adoption of responsible research metrics and assessment in South African higher education institutions for more inclusive and equitable research impact assessments.
The provision of goods and governance in local communities during an emergency: Findings from an urban space in southern Africa
Authors: Lambrechts Derica
Published: July 2024

The provision of political goods and governance in marginalised local communities, located in Cape Town, South Africa, during the national lockdown periods (due to the COVID-19 pandemic) is described. The focus is on an African city, drawing attention to the growing importance of urban governance on the continent. Rapid urbanisation and emergency periods (such as the pandemic) are adding to the complexity of the urban space. This study found that communities in the city relied mostly on themselves for the provision of goods, and that the provision of security remains a critical political good, informing governance. However, the findings confront literature on a hierarchy of political goods, in which security is at the apex. In the given context, the sequence of the provision of goods changes to a non-hierarchical process. The fulfilment of other political goods will facilitate improved provision of security. Good governance needs to be informed by an integrated approach to, and the synchronous fulfilment of, political goods.
Dental metrics of Sahelanthropus tchadensis: A comparative analysis with apes and Plio-Pleistocene hominins
Authors: Neves Walter , Valota Leticia , Monteiro Clovis
Published: July 2024

Since discovery and description of the species, Sahelanthropus tchadensis has been at the centre of a great discussion around its classification as a hominin – the first of our lineage – or an ape. Many studies have been conducted in order to clarify this question, especially studies based on the morphology of the cranium and the post-cranial remains. In this study, we analysed the posterior dentition of S. tchadensis in relation to those of other hominins and chimpanzees, using a multivariate comparative metric analysis. Our results suggest that the posterior dentition of the Chad material lies in the range of well-established early Plio-Pleistocene hominins, supporting its classification as part of the hominin lineage.
Catalysing gender transformation in research through engaging African science granting councils

Published: July 2024

Science investments should benefit everyone; however, research still predominantly lacks gender integration, resulting in incomplete findings and inequitable outcomes. Moreover, despite some progress, gender disparities persist in the research workforce. Research funders, including science granting councils, are pivotal in driving gender transformation through shaping knowledge production and research infrastructure. We report on key findings from the Science Granting Councils Initiative (SGCI) in Sub-Saharan Africa (SSA) Gender Equality and Inclusivity (GEI) Project – a multi-year participatory intervention aimed at strengthening the capacities of councils to integrate GEI across their functions. Participating councils were located in 13 African countries, and their actions spanned four domains: building organisational GEI infrastructure; reshaping norms, practices, and power relations that perpetuate gender inequality; implementing targeted measures to address women’s unequal access to resources and research opportunities; and promoting collective ownership of efforts to advance GEI in the research and innovation ecosystem.

Miradas a la diversidad etnolingüística en una ciudad mexicana
Authors: Canuto Castillo Felipe ,   Universidad de Guanajuato (México)
Published: July 2024

La presencia indígena en las ciudades mexicanas suele evidenciar diferentes situaciones en su relación con la alteridad citadina: desde expresiones que la consideran ajena y no deseada debido a que se le relaciona, en general, con la “tradición” y el “atraso” hasta la aceptación, inclusión y reconocimiento (CDI, 2006; Jasso, 2011). La manera como en general se tiende a identificar a este sector de la población es por los diacríticos culturales, entre ellos, le lengua que habla o la manera como habla español. La población india/indígena1 ha residido en las ahora ciudades y metrópolis mexicanas a lo largo de la historia. El caso que se aborda en esta investigación es el de León, Guanajuato, una localidad que se fundó como villa española en 1576 en un territorio que era ocupado por chichimecas. Desde los primeros años de su existencia llegaron otomíes y purépechas que se asentaron en los entonces pueblos de San Miguel y El Coecillo; además, arribó gente de origen africano que llegó a ser la más numerosa en la cabecera.

Els nous imaginaris culturals
Authors: autores Varios
Published: July 2024

Aquest seguit de fitxes temàtiques té una pretensió bàsica que és explicar amb una mica més de detall un seguit d'aspectes recollits al llibre en paper Els nous imaginaris culturals. Espiritualitats orientals, teràpies naturals i sabers esotèrics, per facilitar la comprensió del lector. És evident que no pretén ser una exposició exhaustiva de tot el que es fa en l'àmbit considerat alternatiu i només presenta teràpies i pràctiques referides per algú, ja que totes han estat comentades o practicades en algun moment per algun dels informants entrevistats. La bibliografia que acompanya les fitxes és la recomanada a aquelles persones que vulguin aprofundir encara més.

Authors: Flores Fillol Ricardo , Pérez Lacasta María José
Published: July 2024

Aquesta col·lecció de problemes constitueix un material de suport per a l'assignatura dEconomia Industrial en el marc del grau d'Economia. Shi inclou un bloc de monopoli (temes 1-3) i un altre d'oligopoli (temes 4-6). Al bloc de monopoli, estudiem com lempresa utilitza el poder de mercat per discriminar preus i condicionar les relacions verticals amb altres empreses. Al bloc d'oligopoli, estudiem com el poder de mercat dóna lloc a un entorn d'interacció estratègica entre empreses, on les decisions que pren una determinada empresa afecten els seus propis beneficis, però també els d'altres empreses que operen al mercat. En aquest bloc estudiem la competència simultània i seqüencial en quantitats, així com models de diverses etapes amb diferenciació de producte i competència en preus.

120 exercicis resolts de comptabilitat financera superior
Authors: Monclús Guitart Ricard , Vidal Blasco Maria Arántzazu
Published: July 2024

Aquest llibre és la conseqüència lògica del ja publicat en aquesta mateixa col·lecció titulat Lliçons de comptabilitat financera superior. En comptabilitat sovint un llibre de teoria requereix un llibre d’exercicis pràctics que permeti arrelar millor els conceptes. I això és més necessari quan la matèria comptable tractada està regulada en codis, lleis i tractats, com l'anomenada comptabilitat de societats. En aquest cas els exercicis i problemes intenten plasmar amb nombres tot allò que el legislador ha exposat en lletres i percentatges.
Enhancing Mechanical Properties of Aluminium-Based Biocomposites through the Addition of Hybrid Reinforcing Particulates
Authors: Chukwuneke JL , Olisakwe HC , Nnakwo KC
Published: July 2024

This study looks into the improvement of mechanical properties in Al-7Mg-2Si-0.1Nb-based biocomposites by incorporating hybrid additions of Irvingia Wombolu Shell Particulates (IWSP) and Mangifera indica shell particulates (MISP). The biocomposites were created using the stir-casting technique. Tensile, hardness, and impact strength were used to determine the mechanical properties of the developed biocomposites. The study shows that the additions of IWSP and MISp have a significant impact on the biocomposites’ properties. The addition of hybrid 2wt% IWSP and 10wt% MISP resulted in a higher percentage elongation compared to the base alloy. The ultimate tensile strength of the biocomposites increased significantly with the addition of both IWSP and MISP, peaking at 6wt% IWSP and 6 wt% MISP. The hybrids of IWSP and MISP consistently demonstrated higher tensile strength, reaching a maximum ultimate tensile strength of 132 MPa. The hardness properties of the biocomposites improved with the addition of IWSP and MISP, with the highest values observed in hybrid combinations of 6 wt% IWSP and 6 wt% MISP. Specifically, the addition of 6wt% IWSP and 6wt% MISP resulted in a remarkable 34.9% increase in hardness. The study found that adding IWSP and MISP significantly improved the impact strength of the Al-7wt%Mg-2wt%Si-0.1wt%Nb alloy matrix, with a maximum value of 45 J at a hybrid 6 wt% IWSP and 6 wt% MISP. These findings demonstrate the ability of hybrid additions to improve the mechanical properties of Al-7Mg-2Si-0.1Nb-based biocomposites, making them a promising candidate for a variety of engineering applications.

Speakezio Application as an Alternative and Augmentative Communication Media for Cerebral Palsy Students
Authors: Eliyas Andri , Susetyo Budi , Nursaniah Sofi Septiani Julaeha
Published: July 2024

The obstacle experienced by most children with cerebral palsy is limited communication skills. This is due to disorders of the speech organs or limitations in receptive and expressive language abilities experienced by children with cerebral palsy. So, when communicating, you need alternative augmentative media or communication systems (AAC) that can help you communicate. This research aims to develop the Speakezio application as AAC media. The method used is the RD (Research and Development) research method with a qualitative approach. This research involves one subject (single subject) which is used as a model in developing applications. This research obtained results in the form of the Speakezio application which was developed based on the results of assessments on target subjects and trials of the application as a media for the AAC system. The trial results show that this application can improve children's receptive and expressive language skills. Apart from that, this application can help communication between children and parents so that parents can more easily understand the messages conveyed by children.
