Published: August 2024

Abstract. To meet the growing global demand for metal resources, new ore deposit discoveries are required. However, finding new high-grade deposits, particularly those not exposed at the Earth's surface, is very challenging. Therefore, understanding the geodynamic controls on the mineralizing processes can help identify new areas for exploration. Here we focus on clastic-dominated Zn–Pb deposits, the largest global resource of zinc and lead, which formed in sedimentary basins of extensional systems. Using numerical modelling of lithospheric extension coupled with surface erosion and sedimentation, we determine the geodynamic conditions required to generate the rare spatiotemporal window where potential metal source rocks, transport pathways, and host sequences are present. We show that the largest potential metal endowment can be expected in narrow asymmetric rifts, where the mineralization window spans about 1–3 Myr in the upper ∼ 4 km of the sedimentary infill close to shore. The narrow asymmetric rift type is characterized by rift migration, a process that successively generates hyper-extended crust through sequential faulting, resulting in one wide and one narrow conjugate margin. Rift migration also leads to (1) a sufficient life span of the migration-side border fault to accommodate a thick submarine package of sediments, including coarse (permeable) continental sediments that can act as source rock; (2) rising asthenosphere beneath the thinned lithosphere and crust, resulting in elevated temperatures in these overlying sediments that are favourable for leaching metals from the source rock; (3) the deposition of organic-rich sediments that form the host rock at shallower burial depths and lower temperatures; and (4) the generation of smaller faults that cut the major basin created by the border fault and provide additional pathways for focused fluid flow from source to host rock. Wide rifts with rift migration can have similarly favourable configurations, but these occur less frequently and less potential source rock is produced, thereby limiting potential metal endowment. In simulations of narrow symmetric rifts, the conditions to form ore deposits are rarely fulfilled. Based on these insights, exploration programmes should prioritize the narrow margins formed in asymmetric rift systems, in particular regions within several tens of kilometres from the paleo-shoreline, where we predict the highest-value deposits to have formed.

Published: August 2024

Drug-resistant epilepsy presents significant challenges in treating epileptic patients, leading to recurrent seizures and necessitating the use of polypharmacy with anti-epileptic drugs. Both of these conditions contribute to increased oxidative stress, which is detrimental to the brain. The aim of this study was to determine the role of vitamins C and E in reducing oxidative stress and seizure frequency in drug-resistant epileptic patients. This was a double-blinded, randomized clinical trial with a placebo, parallel design, and block randomization. The subjects were drug-resistant epileptic patients aged 1–18 years who received routine treatment. Randomization was performed on 100 patients who were divided into the treatment or placebo groups. The patients received a combination of vitamin C (100 mg/day) and vitamin E (200 IU/day for those <5 years or 400 IU/day for those ≥5 years) or a placebo for eight weeks. Malondialdehyde (MDA) levels and seizure frequency were measured prior to and after the intervention. A total of 42 and 46 patients were followed till the end of the study in the intervention and placebo groups, respectively. Our data indicated that the MDA levels prior to treatment were not significantly different between the treatment and placebo groups (0.901 vs 0.890 mmol/mL, p=0.920) and were significantly reduced after the treatment in both the treatment group (p<0.001) and placebo group (p=0.028). The changes in MDA levels (between post- and pre-treatment) were also not significantly different between the two groups (p=0.181). Our per-protocol analysis indicated that the reduction in seizure frequency was significantly higher in the treatment group compared to the placebo group (95% vs 35%, p<0.001), with 92% and 60% relative and absolute risk reduction, respectively. The intention-to-treat analysis also indicated that the reduction in seizure frequency was significantly higher in the intervention group than in the control group (80% vs 32%, p<0.001), with relative and absolute risk reduction of 70% and 48%, respectively. There was no significant relationship between changes in MDA levels and seizure frequency in either group. In conclusion, vitamins C and E could reduce seizure frequency and, therefore, could be considered as adjuvant therapy in drug-resistant epileptic patients.

Published: August 2024

Recent studies highlighted the role of platelet-rich plasma (PRP) in progenitor cell homing, migration, and nerve cell regeneration while also inhibiting fibrosis and apoptosis in cavernous nerve injury (CNI). The aim of this study was to investigate the effect of PRP administration on axon and collagen regeneration in CNI. A true experimental study using a post-test-only control group design was conducted. Twenty-five male Wistar rats (Rattus norvegicus), weighing 200–300 grams, were divided into five groups: two control groups (sham procedure and negative control), and three experimental groups receiving local PRP, intraperitoneal PRP, and a combination of local and intraperitoneal PRP. The cavernous nerve was injured with a hemostasis clamp for one minute before 200 µL of 200 PRP was injected locally, intraperitoneally, or both, depending on the group. After four weeks, the rats were euthanized, tissue segments (2 mm) from each cavernous nerve and mid-penis were collected and analyzed for collagen density, axon diameter, and number of myelinated axons. Our study found that collagen growth was slower in CNI group without PRP (sham procedure) compared to all PRP groups (local, intraperitoneal, and combination). The intraperitoneal PRP group had the highest collagen density at 5.62 µm; however, no significant difference was observed in collagen density among all groups (p=0.056). Similar axon diameter was found across the groups, with no statistically significant difference observed (p=0.856). In the number of myelinated axons, a significant difference was found among all groups with significantly more axons in local PRP and combined local and intraperitoneal PRP groups compared to others (p=0.026). In conclusion, PRP administration improved a number of myelinated axons in CNI, suggesting PRP role in CNI regeneration and the potential for an innovative approach to treating erectile dysfunction associated with CNI.

Published: August 2024

Osteoarthritis (OA) is a complex and common condition, especially affecting the knees due to their weight-bearing role. Traditionally seen as a degenerative disease, OA is now understood to have both mechanical and inflammatory causes. Despite its increasing prevalence, there is limited data on OA in Indonesia, resulting in low awareness among clinicians and the public. The aim of this study was to describe the OA burden in Indonesia, focusing on its prevalence, incidence, and years lived with disability (YLD) from 1990 to 2019, using data from the Global Burden of Disease (GBD) study 2019. A descriptive cross-sectional study was conducted to examine the prevalence, incidence, and YLD of OA in Indonesia from the GBD study 2019. OA prevalence and YLD were compared to other countries according to similar social demographics and geographical proximity. OA YLD was also compared to the top causes of death and disability YLD in Indonesia. The study found that OA cases in Indonesia more than doubled from 1990 to 2019, with increases of 153.12% in males and 143.36% in females. Similar trends were observed for knee OA. The age-standardized prevalence rate in Indonesia increased by 10.03% in males and 8.42% in females, and these were higher compared to China, India, Singapore, and the global average. Younger people had a higher OA prevalence rate growth than older groups. The incidence rate for OA also rose significantly, with males seeing a 10.89% increase to 290 per 100,000 people and females with an 8.57% increase to 384 per 100,000 people. Despite lower overall burden rates compared to some countries, Indonesia experienced significant growth in YLD due to OA (12.16% in males and 9.65% in females) since 1990. Although OA was less burdensome than stroke, diabetes, low back pain, and chronic obstructive pulmonary disease (COPD), its YLD growth rate was higher. In conclusion, OA prevalence and incidence in Indonesia significantly increased from 1990 to 2019, with a notable rise among younger populations. OA had a higher YLD growth compared to several other major diseases in Indonesia, highlighting the need for early detection and preventive measures, particularly for the younger population.

GENDERED PERSPECTIVES IN SELECTED ZIMDANCEHALL BILINGUAL SONGS: AFRICANA WOMANISM
Authors: Roya Witness , Ngcobo Sandiso , Ndaba Nobuhle Elizabeth
Published: August 2024

There is no study which is based on lyrics of songs about a sextape. Hence, the purpose of the study was to understand the gendered perspectives of four Zimbabwe singers towards explicit recording as reflected in the lyrics of their songs. Africana Womanism was deployed as a theory on the relationship between black males and females. The methodology was Critical Discourse Analysis in which purposefully selected artistes’ music lyrics were analysed. D Flexx’s song, “Hombe Yalevels”, “Ane hombe dzinotapira” (Ndunge Yut), “Tsamba kuna Levels” (Lorna Real Love) and Libronie’s “Ane hombe” which were released after the sextape scandal were examined in this study. From the findings, we argue that singers of the four songs failed Shashl as a woman and fellow musician by focusing on DJ Level’s perceived sexual prowess. Public figures ought to consult advisers, managers and veterans in their fields and government departments should partner stakeholders like businesses, brand experts and counsellors to explain the need for maintaining integrity.
Perceptions of employability within an undergraduate science department: A case study to define current strategies and recommend improvements
Authors:   University of Guyana, Craig Kimberly
Published: August 2024

Perceptions of employability in academia are largely shaped by influences and personal experiences. As a substantial amount of a student’s university life is curriculum-based, the issue of whether the university is the ideal place to prepare students for employability is worth examining. This research investigated employability perceptions of an undergraduate science department, along with the influences and approaches taken by the University to address employability. The research questions aimed to determine perceptions of employability by students, graduates, and lecturers, and current strategies being used by the University to improve perceptions of employability. This study applied the pragmatic approach and a mixed-methods design through the use of questionnaires and semi-structured interviews. Qualitative data was analysed using the following themes: perceptions, influences, strategies, and outlook, while quantitative data was analysed using chi-squared analysis. The results demonstrated that robust methods for enhancing employability should be implemented to produce a more skilled or equipped workforce, such as providing opportunities for internship, networking, and short-courses. Further research was recommended to investigate perceptions of employability at other University departments to gain a more holistic understanding of the issues and employ best methods and practices that would benefit all graduates. Such a study would also contribute to greater understanding of the evolving role of universities in enhancing employability.

Polynomials on Banach Lattices
Authors: Ryan Ray
Published: August 2024

Homogeneous polynomials are vital in the study of analytic functions on Banach spaces, as they are the components of the Taylor series that represent the functions locally. As most of the classical Banach spaces are Banach lattices, it is natural to work with polynomials that are coherent with the lattice structure. Thus, we study regular homogeneous polynomials, as they have a modulus that is a positive homogeneous polynomial. We demonstrate some applications, to analysis on Banach spaces with an unconditional basis, and to the radius of analyticity in a real Banach space. We also look at an application to the computation of the radius of convergence of power series on Banach lattices. We then consider the class of orthogonally additive polynomials, particularly on spaces of continuous functions, where some interesting geometric phenomena are seen.
OPEN-SETTLEMENT AND BURIAL MOUND NEAR THE VILLAGE OF BIRULI, DOKSHITSKY DISTRICT, IN THE CONTEXT OF SYNCHRONIC ARTEFACTS OF THE LATE 1ST – EARLY 3RD MILLENNIUM AD IN THE UPPER BEREZINA DNIEPER REGION
Authors: VOITEHOVICH A.
Published: August 2024

Some factors which were reflected in the time of origin of a trade and craft open-settlement in the upper reaches of the Berezina River in the 10th century, located near the present-day village of Biruli, Dokshitsky district are being presented in the article. This favourable geographical position (the Berezina Dnieper connected Central Belarus with the Dnieper and gave access to the rivers of the Neman basin), natural conditions (a large lake, forest lands rich in game), hill-fort located near the river (the only one in the region near the Berezina). The settlement provided the population of the region with imported goods and quality ones of its own production, including pottery, which was unknown there until then. The local population supplied the former with fur and possibly slaves. This place was permanently inhabited by craftsmen – blacksmiths, jewellers, potters and representatives of the trading class, who at the same time fulfilled a military function. This environment formed the local elite, the burials of representatives of whom were recorded in the burial mounds. By the middle of the 11th century the trade route connected with the Berezina River gradually decayed and ceased to function. At that time, activities ceased at the settlement near the hill-fort near the village of Biruli. Other ones acquired exclusively agrarian in character in the region.
DESCRIPTION OF CLIMATIC PHENOMENA IN THE SECOND HALF OF THE XVII–XVIII CENTURIES IN THE MOGILEV CHRONICLE OF T.R. SURTA AND TRUBNITSKY
Authors: SUBOTSIN А.
Published: August 2024

The article discusses the features of the description of climatic phenomena in the Mogilev chronicle of T.R. Surta and Trubnitsky. The chronicle is a valuable historical source for reconstructing the climate of the second half of the XVII – XVIII centuries. It mentions, first of all, climatic disasters, which are reflected in records of abnormally cold winters and unstable weather in the spring and summer seasons. The chronicle pays great attention to the facts of famine, rising prices for bread and other food products, which was the result of low yields, caused by unfavorable climatic conditions. The authors of the Mogilev Chronicle also described cases of locust invasions, which have been observed again on Belarusian lands since the end of the XVII century and are a clear indicator of dry and warm weather.

MODELS AND INSTITUTIONAL FACTORS OF THE CAREER OF HEADS OF LOCAL PUBLIC AUTHORITIES AND MANAGEMENT (1965–1985)
Authors: ELIZAROV S.
Published: August 2024

The article deals with the issues of personnel policy in relation to the heads of local government bodies – the chairmen of the executive committees of the Soviets of the period of "developed socialism". In the 1960s and 1980s, there were models of career growth worked out in practice, which assumed consistent, starting from grassroots leadership positions, and gradual, without sudden jerks, promotion along the vertical of power and management. Based on the analysis of statistical material and the study of the biographies of specific heads of local state bodies, three main trajectories of their career growth are distinguished: "Soviet-economic", "party-Soviet", "combined". It is noted that the most common was the third option – "combined": the alternation of party, Soviet and economic nomenclature positions. Institutional factors of career growth are highlighted: membership in the CPSU, higher specialized technical or agricultural education, higher party-political education, age and work experience in lower positions (including the beginning of work as workers or collective farmers).

The article was prepared as part of the task of the state scientific research program "Society and Humanitarian Security of the Belarusian State", subprogram "History", topic 12.1.3.11 "Local government bodies of the Byelorussian SSR – the Republic of Belarus: organizational, legal, material, financial and personnel foundations of functioning (1944–2020)" for 2021–2025.

Postsecondary retention of students in STEM continues to be a challenge. Access to mentorship, experiential learning activities, and lack of intentional K-12 preparation impact retention in STEM for students of color in particular. Career development interventions that provide focus
on self-exploration, career decision-making, and career thoughts can increase retention and decidedness for students. The purpose of this qualitative study was to illuminate the experiences of undergraduate STEM interested students (specifically students of color) in a STEM focused career
planning course. Our primary research question was, “How do students in a STEM focused career planning course describe their experiences from the course?” The researchers found that, overall, students had a positive experience in the class and it helped them find mentorship, become
more decided in a major, and learn about the world of work.

Analysis of Presupposition in English Teaching Materials at SMAN 4 Palu
Authors: Zulfikri Zulfikri
Published: August 2024

This study aims to analyze the types of presuppositions in English teaching materials at SMAN 4 Palu. The method used in this research is discourse analysis of the English textbooks used in the eleventh grade, focusing on identifying examples of existential, factual, and structural presuppositions. Data were collected through critical discourse analysis techniques and interviews. The results of the analysis show that the teaching material at SMAN 4 Palu contains various types of presuppositions that can influence students' understanding. Existential presuppositions, such as "The President of the United States," assume knowledge about a particular entity, whereas factual presuppositions, such as "John stopped smoking," assume the truth of information that students may not know. Structural presuppositions, for example, the use of the word "again" in "He came back again," involve hidden assumptions that require contextual background for proper understanding. Findings show that teaching materials often contain presuppositions that are not relevant to students' local contexts, such as the use of examples from Western culture that students may be unfamiliar with. Therefore, adapting teaching materials to local contexts is very necessary. This research recommends the involvement of Palu regional teachers and education experts in curriculum development and the adaptation of teaching materials to make them more relevant to students' daily lives. By integrating local culture into teaching, students' understanding of texts can increase significantly, enhancing learning effectiveness and supporting the achievement of optimal learning outcomes.

Published: August 2024

Fish is an essential component of the diet of the most popular in India. Fish production in India has increased at a higher rate compared to other food items. The most widely used time series models ARIMA was applied for modelling and forecasting of total, inland and marine fish production in India for a period from 1978-79 to 2021-22. The collected data during the third decade was found highly consistent and stable with less variability. The lowest mean fish production growth rate was observed in all three categories viz., Inland, Marine and Total fish production, in the fourth decade of study period, i.e., 2003-2012. Present study revealed that the model ARIMA (0,1,3) was best fit for forecasting marine fish production of India while ARIMA (0,2,1) was best model for both inland and overall fish production. The model forecasted that the fish production in all three categories would be in increasing trend for the next five years from 2022-23 to 2026-27 with highest estimated marine, inland and total fish production of 42.18 lakh tonne 162.78 lakh tonne and 211.64 lakh tonnes respectively during the year 2026-27.
A religião em Gilberto Freyre - Sincretismo e a civilização «cristocêntrica»
Authors: Oliveira Nuno
Published: August 2024

In this article, I seek to dialogue with the thesis of alternative modernity in Freyre’s work from a less explored dimension: the religious one. Using texts and excerpts explicitly problematizing religion’s role in Brazil’s social formation, I show how we can read this alternative modernity in the light of an «alternative religiosity». This text then explores the author’s intuition of the influence of the Orient in the forms of the social organization of colonial Brazil. It is argued that this should be understood as refracted by Christianity and that the latter assumes a fundamental role in the cultural production of hybridity. This combination has its ethical core, allowing us to understand the utopian sense of some of Freyre’s theses. A sense which cannot be dissociated from a very particular attempt at the «invention» of national identity.

Background: Anterior combined latissimus dorsi and teres major (aLDTM) tendon transfer has shown promise as a treatment for anterior superior irreparable rotator cuff tears (ASIRCTs). Our study aimed to compare aLDTM clinical outcomes for ASIRCTs between young and elderly patients.Methods: This retrospective study reviewed data from patients who underwent aLDTM tendon transfer for ASIRCTs with minimum 2-year follow-up. Clinical evaluations included visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), active range of motion (aROM), strength, and complications. Radiologic assessments included acromiohumeral distance, Hamada classification, and integrity of transferred tendon. Patients were divided into group total (all ages), group old (≥70 years), and group young (≤60 years).Results: A total of 123 patients were enrolled with 39 in group young (mean age, 56.6±4.9 years) and 27 in group old (mean age, 73.6±2.3 years). Postoperatively, both groups showed significant improvements in VAS, ASES, and SANE scores and improved aROM for forward elevation, abduction, and internal rotation. No significant differences in clinical coutcomes were noted between the groups. Furthermore, similar rates of complications, including retears and postoperative infections, were observed across all three groups.Conclusions: Our study highlights the effectiveness of aLDTM transfer for ASIRCTs with minimal glenohumeral arthritis, demonstrating similar outcomes in both group young and group old patients. Moreover, patients in these distinct age groups showed comparable clinical results when compared to group total.Level of evidence: III.

Differential equations have a remarkable ability to predict the world around us. They are used in a wide variety of disciplines, from biology, economics, physics, chemistry and engineering. The study of existence and uniqueness, periodicity, asymptotic behavior, stability, and methods of analytic and numerical solutions of fractional differential equations have been studied extensively in a large cycle works; Especially, The study of existence and uniqueness of solution of fractional partial differential equations are then proved by mani methods as: the well-known Lax–Milgram theorem, Energy estimate and fixed point theorem... Among them, we only mention here the apriori estimate method (energy inequality method). The current piece of work concentrates on exploring the existence and uniqueness of a solution for a non-linear boundary value problem that has integrable conditions in the case of fractional partial differential equations. For this we split the proof into two sections: linear and non-linear problem; for the associated linear problem, we derive the a priori bound and demonstrate the density of the operator generated by the problem posed; we solve the non-linear problem by introducing a iterative process. The results show the efficiency of energy inequality method in the case of time fractional order differential equations with integrable conditions our results illustrate the existence and uniqueness of the continuous dependence of solution on fractional order. The work of the authors could be considered as a contribution to the development of the functional analysis method. And to conclude we argue that the research carried out in this article could serve as a contribution for possible studies in the field of applied mathematics.

Este estudo consiste na socialização de um dos achados de nossa pesquisa de mestrado em Educação Contemporânea, financiada pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior. A questão-problema que orientou nossa pesquisa foi: Quais as possíveis contribuições da teologia da tradição Hare Krishna e sua tradução em práticas pedagógicas na perspectiva de uma educação centrada na sabedoria? Nesta esteira indagativa, objetivamos relacionar a noção de sabedoria com a educação a partir da tradição Hare Krishna. Para tanto, percorremos um trajeto teórico-metodológico a partir da teologia da tradição, a Bhagavad-Gita e dos aportes interpretativos da mesma de Swami Prabhupada (2001) e Howard Resnick (2015), além das Epistemologias do Sul de Santos (2006a; 2006b; 2010; 2018); caminhamos também com Freire (1987; 1996) e Souza (2009). Metodologicamente, utilizamo-nos de Santos (1983), Goldenberg (2001), Gatti (2007), Demo (2000), Gill (2008), Minayo (2012), Lage (2005, 2013) e Bardin (1977). Entre nossos principais achados está a noção de pedagogia da alimentação, que corporifica modos de vida que tensionam crenças basilares em relação à vida, à natureza e exerce crítica aos modos utilitaristas de produzir e de ingerir alimentos. Essa compreensão provoca aprendizados que possibilitam transformações existenciais e ético-políticas, articulando a sabedoria e a formação humana, abarcando dimensões vivenciais e interligando os aspectos intra-inter e transpessoais dos sujeitos, das culturas e sociedades.

O artigo apresenta o projeto de pesquisa e desenvolvimento intitulado "Motor Prefix", cujo objetivo é automatizar o processo de pré-fixação dos motores das unidades externas dos condicionadores de ar modelo Split. O projeto envolve o uso de uma esteira para transportar os motores, onde são parafusados automaticamente por um conjunto de quatro parafusadeiras. Após a fixação, uma garra especialmente projetada é responsável por transferir os motores para a esteira de saída. Essa abordagem automatizada visa melhorar a eficiência e a precisão do processo, reduzindo a necessidade de intervenção manual e aumentando a produtividade, mas também mitiga problemas comuns na montagem manual, como a fixação inconsistente ou incompleta do parafuso, aplicação incorreta do torque, parafusos frouxos ou perdidos, além de reduzir riscos ergonômicos e o desgaste dos operadores devido à repetitividade do trabalho Este projeto se alinha com as iniciativas da indústria 4.0 e conceitos de Fábrica Inteligente para transformar fábricas em instalações inteligentes e conectadas, utilizando tecnologias avançadas como IoT (Internet of Things), IA (Inteligência Artifical) e robótica para otimizar a produção. O projeto faz parte do plano estratégico de P&D (Pesquisa e Desenvolvimento) da empresa, focando em pesquisa aplicada para a automatização da pré-fixação dos motores, uma técnica já empregada em diversos setores da empresa. Para desenvolver o protótipo, foi adotada uma metodologia que inclui o levantamento de requisitos, projeto mecânico usando a ferramenta PTC CREO, programação do sistema de controle via CLP (Controlador Lógico Programável), Diagrama Ladder, desenvolvimento de uma IHM (Interface Homem-Máquina) para monitoramento e controle do processo, e a realização de testes funcionais para garantir que o protótipo atende às necessidades de produção.
