Coach’s self-efficacy and athlete’s perceived training effectiveness: Specific context of WMSU sports development program
Authors: Jalandoni Albert A.
Published: January 2025

Sports development programs are essential in promoting physical, mental, and social growth among individuals, especially students and young athletes. The programs offer organized avenues for individuals to enhance their athletic abilities, increase fitness standards, and cultivate qualities such as discipline, teamwork, and resilience. This mixed-method paper analyzed the self-efficacy of sports coaches from Western Mindanao State University (WMSU) in terms of their competence, management, and selection. Perceptions from students were used to evaluate the efficacy of sports coaches in these constructs. Interview transcripts provided in-depth perspectives about the challenges that the students and coaches experience, which impacted the overall implementation of the sports development program. Findings indicated that sports coaches at WMSU exhibited high levels of self-efficacy in competence, management, and selection processes—which the student athletes confirm. Coaches believed they were capable of successfully training athletes, managing sports programs, and selecting new talents. This belief in their abilities positively affected the athletes they trained, contributing to the overall success of the sports development program. However, despite high self-efficacy, coaches and student-athletes faced challenges, such as inadequate facilities, limited funding, and insufficient institutional support. These external factors, impeded the full effectiveness of the sports development program, leading both coaches and athletes to view certain aspects of the program's management and selection processes as less effective. Addressing these hindrance stressors, particularly through increased financial support and upgraded facilities, could significantly improve the overall impact of WMSU's sports development program.

Com o crescimento do interesse no aproveitamento da energia solar no estado do Amapá, através de sistemas fotovoltaicos, a estimativa de radiação solar global diária média mensal, através de modelos matemáticos, é de grande utilidade na prospecção de regiões com potencial para exploração dessa energia. Assim, o objetivo deste estudo foi avaliar três modelos de estimativa de radiação solar para Macapá com base na amplitude térmica do ar, utilizando os modelos de Bristow e Campbell (B-C), Hargreaves (HG) e Hunt (HU), estendidos para medidas de média mensal. Os modelos foram calibrados e validados tomando como base seis anos de dados meteorológicos. O desempenho de cada modelo foi avaliado pelo coeficiente de determinação, raiz do erro médio quadrático, índice de concordância de Willmott, coeficiente de correlação de Pearson e o índice de desempenho (c). Os resultados mostraram que os modelos B-C e HU apresentaram melhores desempenhos, com boas acurácias encontradas no índice de Wilmott (0,93 e 0,92), erros médios quadráticos (1,37 MJm-2d-1 e 1,41 MJm-2d-1), medianas precisões R2 (0,78 e 0,76), sendo classificados como desempenho muito bom na estimativa da radiação solar global diária média mensal para Macapá. É de se destacar que a pequena diferença entre os desempenhos dos modelos avaliados e a proximidade dos resultados com os encontrados na literatura cientifica, indica que o modelo de Hargreaves, calibrado com um coeficiente, é também atrativo e robusto para Macapá.

A passivação das superfícies em células solares bifaciais visa o aumento da eficiência e da bifacialidade. O objetivo deste trabalho é analisar a influência da vazão de oxigênio e nitrogênio na espessura da camada de óxido de silício crescida no emissor e no campo retrodifusor para passivar células solares bifaciais PERT base p. Três processos de oxidação térmica seca foram desenvolvidos para crescer a camada de óxido de silício para passivação: com vazão padrão de oxigênio, com redução de 30% da vazão de oxigênio e com redução de 30% da vazão de oxigênio e adição de nitrogênio. A caracterização das camadas foi realizada por espectroscopia por energia dispersiva e pela determinação da espessura e do índice de refração com a técnica de elipsometria. A concentração de oxigênio e a espessura da camada de óxido de silício no emissor foi maior que no campo retrodifusor. Com o processo com redução de oxigênio, observou-se uma tendência de aumento da concentração de oxigênio na camada de passivação no emissor e no campo retrodifusor, em comparação com o processo com vazão padrão de oxigênio. A espessura do óxido de silício no campo retrodifusor foi maior, mas no emissor a espessura da camada foi similar. Também se constatou a tendência de aumento do índice de refração do óxido de silício no emissor com a redução de oxigênio. Para o processo com nitrogênio, ocorreu menor taxa de crescimento da camada de óxido de silício no emissor e a diferença entre a espessura da camada de passivação crescida no emissor e no campo retrodifusor foi a menor. Concluiu-se que é possível reduzir a vazão de oxigênio em 30% para a passivação de células solares PERT base p.

Published: January 2025

The current investigation reports the influence of siliconized slag powder on the mechanical properties of epoxy composites. At first, the received slag was crushed and milled followed by sieve analysis. The chemical composition of the slag waste of the steel-making process was inspected using X-ray fluorescence spectroscopy (XRF). Second, the treated slag was mixed with silicone rubber at high speed to produce siliconized slag. Then slag with and without silicon was incorporated into epoxy resin to produce epoxy composites, and mixing was done at the high-speed mixer. The mix was poured into Teflon-coated molds and allowed to harden for 3 days at room temperature. The mechanical performance of the prepared composites was inspected. Chemical functional groups and molecularstructure were analysed with attenuated total reflectance infrared spectroscopy (ATR-IR). The samples were examined with a Scanning electron microscope associated with energy-dispersive X-ray spectroscopy (SEM/EDX). Such a technique was used to obtain an idea of the fracture mode and the dispersion pattern of slag powder within the matrix and the chemical composition of the slag.

The experiments were carried out to examine the possibility of utilizing waste slags generated in fire smelting processes. Metallurgical slags - Fe-As Alloy, Lead Slag and Ground Pb Slag were subjected to leaching with nitric acid with varying concentrations, at 100°C for 1 h under atmospheric pressure. The possibility to recover iron, copper, lead, cadmium, cobalt and molybdenum was examined. Elements with high enough content in raw material can be successfully leached and the plateau of leaching efficiency is reached with 55 wt. % nitric acid in most cases and is recommended for this process. If iron is not targeted for leaching even as low as 30 wt. % nitric acid can be used while maintaining high leaching.

Authors: Suharno Bambang , Nurjaman Fajar , Azizah Aiesha
Published: January 2025

High energy consumption and production costs during the metal-slag smelting in the pyrometallurgical process caused many alternative methods to be developed. Selective reduction technology emerges as a potential solution, enabling the processing of nickel laterite into ferronickel concentrate at lower operational temperatures ranging from 1000°C to 1250°C with the presence of some additives. This work investigated the effect of a combination of two additives, i.e. sodium sulfate and calcium sulfate, on the reduction process of saprolitic nickel laterite on nickel and iron grade and recovery in ferronickel concentrate, phase transformation, and the morphology of the resulting ferronickel particles. The saprolitic nickel laterite, coal as a reductant, sodium sulfate and calcium sulfate as additives were mixed and then pelletized into a 10 - 15 mm diameter. The reduction process of pellets was carried out in a muffle furnace from 1050°C to 1250°C for 60 min, and a magnetic separation process was continued to segregate the ferronickel and impurities. Techniques such as XRF, XRD, and SEM-EDS are employed to ascertain the content of nickel and iron, phase changes, and the microstructure of the ferronickel. The study found that the addition of 10 wt. % of the mixture additives, with the composition ratio of 75 : 25 for sodium sulfate and calcium sulfate, at a reduction temperature of 1250°C, generated the optimum of the nickel content and recovery of 17.06 % and 57.01 %, respectively. It also enlarges the particle size of ferronickel up to 26.94 μm. The combination of sodium sulfate and calcium sulfate as additives could enhance the nickel content and recovery in ferronickel by the mechanism of segregating the nickel and iron from the magnesium silicates phase in saprolite and providing the formation of low-melting point phase of troilite promotes the aggregation of ferronickel particle, respectively.

Authors: Ostachavičiūtė Simona , Mardosaitė Rasa , Valatka Eugenijus
Published: January 2025

Continuous tungsten trioxide (WO3) and porous titanium dioxide (TiO2) films on AISI304 type steel were prepared by electrochemical methods. The morphology and structure of the obtained films were studied by X-ray diffraction analysis and scanning electron microscopy. Oxygen evolution catalyst containing cobalt–phosphate compound was deposited photochemically onto the surface of semiconductor particles. The photoelectrochemical properties of the prepared electrodes were investigated in neutral 0.1 M phosphate buffer solutions. The voltammetric characteristics revealed that the presence of cobalt-based catalyst effectively changes the photoelectrocatalytic activity of WO3 and TiO2 particles. The influence of some synthesis parameters (type of cobalt(II) salt, photodeposition time) on the electrochemical properties of the prepared electrodes was evaluated experimentally.
Adsorption behaviour of camphor on copper electrode
Authors: Survila Arvydas , Kanapeckaitė Stasė
Published: January 2025

Electrochemical impedance spectroscopy was used for investigation of camphor surface activity on copper electrode in acid sulphate solutions. A large frequency dispersion of the differential capacitance is indicative of development of non-equilibrium adsorption layers involving slow relaxation processes. A rather weak adsorption of camphor is enhanced by bromide anions, especially in the presence of Cu(II). The respective orientation of adsorbed camphor dipoles results in the positive shift of the zero-charge potential. The model of the adsorption layer is suggested, according to which specifically adsorbed halides act as species bridging the copper substrate with Cu(I)-camphor surface complexes. Nevertheless, this does not lead to the exclusion of surface water and formation of two-dimensional condensed adsorption layers that are typical of less hydrophilic metals.

Ultra performance liquid chromatography (UPLC) coupled with a diode array detector (DAD) and mass spectrometry (MS) was applied for identification of isoflavones and their conjugates in red clover (Trifolium pratense L.) growing in Lithuania. Isoflavones were extracted with methanol/water (9:1, v/v) using sonication for 60 min at room temperature. Optimized separations were carried out on the Acquity UPLC BEH C18 column in the gradient elution mode using the mobile phase composed of water and methanol containing 0.25% (v/v) acetic acid. Based on UV spectra, MS data, elution order and elution profiles, measured before and after acid hydrolysis, a total of 16 isoflavone aglycones, their glucosides and glucoside malonates were identified in red clover extract.

The synthesis and characterization of 13 new 5-carboxyuracil derivatives bearing ester and amide groups is described. Five previously synthesised 5-carboxyuracil esters were prepared by a new procedure using carbodiimide as a coupling reagent. The prepared compounds were tested as inhibitors of DNA polymerases, particularly M. MuLV and HIV-1 reverse transcriptases. In addition, it is shown that the methyl, ethyl, propyl, isopropyl, butyl, cyclohexyl, cyclooctyl, and prop-2-ynyl esters of 5-carboxyuracil are substrates of thymidine phosphorylase, thus allowing enzymatic synthesis of novel modified nucleosides.

2,4-Diazidopyrrolo[2,3-d]pyrimidines were synthesized by the reaction of the corresponding 2,4-dichloropyrrolo[2,3-d]pyrimidines with sodium azide at room temperature. 2,4-Diazidopyrrolo[2,3-d]pyrimidines were shown to exist in an equilibrium with the corresponding 5-azidopyrrolo[3,2-e]tetrazolo[1,5-c]pyrimidine. The proportion of the tetrazole tautomer increases with increasing solvent polarity. The CuAAC reaction of the obtained azides with 3-methylphenyl- and 4-biphenylylethynes afforded the corresponding 2,4-bis(4-aryl-1,2,3-triazol-1-yl)pyrrolo[2,3-d]pyrimidines.

Published: January 2025

This study explores the relationship between financial literacy, consumer communication, and financial decision-making among English Literature students at Universitas Negeri Medan. Using surveys with 40 participants aged 20-24, the research assesses students’ financial literacy levels, preferences for communication formats, and their impact on financial behaviors. Rsults indicate that while most students have a basic understanding of financial concepts, gaps exist in budgeting, selecting financial products, and seeking assistance. Visual formats like videos and infographics are the preferred communication channels, while social media, though widely accessed, often lacks clarity. Only a portion of students applies financial literacy effectively in decision-making, such as evaluating financial products critically or avoiding unnecessary spending.  The findings emphasize the importance of integrating tailored financial education programs with effective communication strategies. Enhancing financial literacy through practical and accessible learning methods can empower students to make informed and strategic financial decisions.
Uncovering the Power of Educational Websites as a Means of English Language Learning: Students’ Perspective
Authors: Sherly Desliyanah
Published: January 2025

Technology is essential to the efficient teaching and learning process. But technological advancement does not ensure that everyone can take full use of it. Acquiring technical literacy or knowing how to utilize it involves more than just learning how to read; it also involves being able to use, access, and integrate technology into the teaching and learning process. Although a lot of people use the internet, not everyone is able to fully utilize its benefits, particularly in the field of education. Learning can be done more quickly and in a number of ways, particularly while learning English. In our nation, English is a foreign language, and students will have a lot of trouble using it. Therefore, in order to help students understand and avoid becoming disinterested in the process of learning English, teachers need to possess additional skills. As a result, providing the internet and educational websites as resources for learning English will benefit both educators and learners. While the use of the internet for educational purposes is not new in our nation, not all institutions are able to put it into practice because of a lack of necessary resources, including computer equipment and internet access.

Published: January 2025

This study explores the current state of circular economy (CE) practices in the Nigerian construction industry, identifying key challenges and opportunities for their implementation. Utilizing a mixed-methods approach, data were collected from 200 survey participants and 20 key informants through structured surveys and semi-structured interviews. The quantitative data were analyzed using descriptive and inferential statistics, including regression and factor analysis, to uncover the relationships between variables and the underlying dimensions of barriers to CE adoption. The findings reveal that while there is a moderate level of awareness and implementation of CE practices, such as waste segregation and the use of recycled materials, these practices are not yet widespread. Major barriers identified include lack of awareness, high implementation costs, and insufficient regulatory support. Specifically, 75% of respondents cited lack of awareness as a significant barrier, and 80% identified high costs as a deterrent. Regression analysis indicated that awareness level, regulatory support, and company size positively influence CE practice adoption, while perceived cost has a negative impact. The study also highlights positive perceptions towards CE practices among industry professionals, with 85% of respondents recognizing their importance for the future of the construction industry. Factor analysis revealed three main dimensions of barriers: financial, awareness and education, and regulatory and policy barriers. Based on these findings, the study recommends targeted educational programs to increase awareness, financial incentives to mitigate cost barriers, and stronger regulatory frameworks to enforce sustainable practices..
Design a PID controller based on grey wolf optimization algorithm for single-area load frequency control
Authors: Jangid Priyanka , Nagar Vishal , Sharma Aditya , Nagar Sonam , Palwalia D. K.
Published: January 2025

This article, focuses on the load frequency control (LFC) of a single-area system with a grey wolf optimization metaheuristic approach. This approach is applied to optimize the PID controller parameters for the effective operation of the system. The grey wolf Algorithm (GWO) has been utilized to optimize the controller’s parameters and minimize the error. SIMULINK Model is used to simulate the Single-area load frequency control (SALFC) with GWO to mitigate the error and frequency fluctuations. The integral time absolute error (ITAE) has been considered as an objective function for optimal search of PID parameters. The frequency performance of the system has been observed without a controller, or any other methods in literature and with the proposed grey wolf optimization (GWO). The simulation response shows in terms of rise time, settling time, and peak time. The performance of the power system has been compared with other approaches namely Particle Swarm Optimization (PSO), and Firefly Algorithm (FFA). The Proposed optimization technique provides a much better response than other strategies.
