The Microstructure, Hardness and Density Investigation of Mg Composites Reinforced with Nanoclay
Authors: Aslan Mikail
Published: January 2025

Magnesium (Mg) stands out as a prevalent material in engineering, finding essential utility as a biomaterial due to its unique combination of low density, stiffness, high damping capacity, superior bending resistance, and impressive specific strength. Despite its high reactivity and somewhat inadequate mechanical properties for rigorous engineering applications, the incorporation of reinforcing nanoparticles has shown significant potential in enhancing the performance of magnesium-based composites. This study investigates the microstructure evaluation, hardness, and density of magnesium composites reinforced with nanoclay using a powder metallurgy approach. Nanoclay was preferred as a reinforcement element at weight percentages of 1%, 3%, 5%, and 7%. The densities of the composites were measured using the Archimedean principle, revealing that the addition of nanoclay generally increases the density of the composites due to the higher density of nanoclay compared to pure magnesium. However, the composite with 5% nanoclay exhibited a lower density than the one with 3% nanoclay, likely due to agglomerations leading to increased internal voids. Surface preparation for Vickers hardness testing involved sanding with 600, 1000, and 2000 mesh sanders, followed by polishing with 6μ and 3μ diamond suspensions. Hardness measurements, conducted using an AOB Vickers microhardness tester, indicated that the highest hardness value was observed in the composite with a 7% weight percentage of nanoclay, demonstrating that nanoclay addition enhances hardness. However, the composite with 3% nanoclay showed lower hardness compared to other reinforced composites. Optical images of the structures revealed metallographic spots indicative of contamination. These findings contribute to the understanding of the structural and mechanical behavior of nanoclay-reinforced magnesium composites, highlighting the potential for optimizing such materials for various applications in automotive, aerospace, and medical fields.
Numerical Investigation of Firing Characteristic of Stochastic Hodgkin-Huxley Neuron under Different Forcing Regimes
Authors: Calim Ali
Published: January 2025

This paper investigates the influence of the ion channel noise, that is one of important internal neuronal noise sources, on the response of a Hodgkin-Huxley neuron in different stimulus regimes. Our results show that, in the case of dc current introduction into neuron dynamics, neuronal firings in excitable neuron emerge with growing firing rate due to increasing ion channel noise. Despite such a relationship between firing rate and channel noise, emergent behaviour is still spontaneous and irregular. However, neuronal firings in spiking neuron skip or terminate due to intermediate level of channel noise. This is known as inverse stochastic resonance phenomenon. We show that firing behaviour of such a spiking neuron is, interestingly, highly irregular around the revealed noise levels and this continues towards higher noise intensities. On the other hand, we examine the influence of channel noise on the neuronal response to a periodic signal primarily with subthreshold amplitude. We show that signal frequency has a significant effect on the response sensitivity related to channel noise intensity whereas, compared to dc current input, firing probability and regularity show a close relationship due to increasing noise. Finally, neuronal behaviour due to ion channel noise in the case of suprathreshold periodic forcing is analysed. Up to a certain level of channel noise, it does not seriously affect number of firings which has a nonlinear relationship with increasing signal frequencies. It is also possible to see inverse stochastic resonance effect at the high frequency regions with the help of relatively high noise. Another interesting finding is that channel noise does not affect the regularity at certain frequencies, yielding the presence of irregular response region at suprathreshold periodic inputs.
A Model Proposal for Estimate the Approxımate Costs and Contract Fees of Public Education Buildings (School Buildings)
Authors: Kesim Servet , Uğur Latif Onur
Published: January 2025

In this study, a method is proposed for the preliminary estimation of school building costs. For this purpose, the projects of 96 school buildings, which were put out to tender by public institutions and the result announcement was published, were provided from the Electronic Public Procurement Platform. These projects are divided into 81 training data and 15 test data. The construction cost of educational buildings through projects may affect the output vectors; “Number of Classrooms, Construction Duration, Total Number of Floors, Floor Height, Building Height, Building Height Class, Basement Height, Earthquake Design Class, Floor Class, Ground Safety Stress, Bed Coefficient, Concrete Class, Number of Elevators, Wet Area, Raft Foundation Height, Floor Area, Basement Area, Total Area" parameters were determined and used in modeling and analysis. Analyzes were carried out with “SPSS Statistics 26” software. Using these parameters, Regression Analyzes (RA) were performed and equations were developed to estimate the costs of educational structures. Approximate Costs and Contract Prices were tried to be estimated with the developed models. The model in which all parameters were used with the created equations was the model with the best correlation level, with the determination coefficient R²=0.900 for the Approximate Cost Price and R²=0.927 for the Contract Price. An error rate of 17,5% was found between the approximate cost estimates obtained using the model and the actual costs. It was determined that there was an 18,2% error between the estimated contract prices and the actual contract prices. The Durbin-Watson criterion was used to check the consistency between predicted results and actual results. As a result, an approach that can estimate the approximate costs and contract prices of school buildings of different types and coefficients with error rates lower than 20% has been created. Both public institutions and contracting construction companies will be able to make realistic cost estimates by benefiting from these modeling, providing time savings. Conducting similar studies by increasing the number of data may be a solution to minimize the error rate in subsequent modeling.
Visible Digital Image Watermarking Using Single Candidate Optimizer
Authors: Akbulut Harun
Published: January 2025

With the advent of internet technologies, accessing information has become remarkably facile, while concurrently precipitating copyright conundrums. This predicament can be ameliorated by embedding copyright information within digital images, a methodology termed digital image watermarking. Artificial intelligence optimization algorithms are extensively employed in myriad problem-solving scenarios, yielding efficacious outcomes. This study proposes a visible digital image watermarking method utilizing the Single Candidate Optimizer (SCO). Contrary to many prevalent metaheuristic optimization algorithms, SCO, introduced in 2024, is not population-based. The fitness function of SCO is designed to maximize the resemblance between the watermarked image and both the host and watermark images. Experiments were conducted on images commonly utilized in image processing, and the results were evaluated using eight quality metrics. Additionally, the obtained numerical results were juxtaposed with those from well-known and widely-used genetic algorithms, differential evolution algorithms, and artificial bee colony optimization algorithms. The findings demonstrate that SCO outperforms the others in visible digital image watermarking. Furthermore, due to its non-population-based nature, SCO is significantly faster compared to its counterparts.
THE EFFECT OF GRAPHENE NANOPARTICLES ON THE MECHANICAL PROPERTIES OF WOVEN ARAMID/EPOXY COMPOSITES
Authors: Şen Ömer , Yıldırım Musa
Published: January 2025

In this study, the effect of the amount of graphene added to aramid fiber/epoxy composites on the mechanical properties of these composites was investigated. In the study, graphene nanoparticles were added to the epoxy matrix at four different rates and mixed by mechanical methods, and then 5-layer aramid epoxy graphene composite plates were obtained using hand lay-up and vacuum infusion methods. Samples were cut from these composite plates according to ASTM 790 for bending test and ASTM D3039 for tensile test and three-point bending and tensile tests were performed. Microstructure examinations were carried out under a macro microscope. After the studies, it was observed that agglomeration occurred in the microstructures of the produced composites. It was determined that graphene added to the aramid epoxy composite increased the bending strength and bending modulus, the highest bending stress was observed in the samples with 1% graphene added. The flexural strength, which compared to the undoped composite, increased about 64 % in this sample. In addition, the highest tensile strength was measured in the undoped sample, and after the 0.25% graphene addition, the tensile strength decreased due to the agglomeration of graphene that occurred in the structure.

Authors: Dikbasan Buğra , Dursun Sami
Published: January 2025

Heavy metals (HMs) are causing an increasing amount of harm to the environment and living organisms. A variety of studies is being conducted to eliminate or diminish such pollutants. In this study, hydrochar was produced from hazelnut waste (HW), and Pb and Cr ion removal research was conducted with this adsorbent. In this way, both the evaluation of HW was provided and the removal of HMs, which are very harmful for the environment. The structural and morphological properties of the produced hydrochars were characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FT-IR), and EDX analyses. The effects of many parameters, such as initial concentration, temperature, adsorbent dosages, contact time, and pH on adsorption were discussed. In the studies executed in different parameter environments, it was determined that hydrochar removed 76% and 67% of Pb and Cr ions, respectively. Also, Langmuir and Freundlich isotherm models, pseudo-first-order and pseudo-second-order kinetic models, and thermodynamic parameters like Gibbs free energy were investigated in order to gain a better understanding of the adsorption system of the generated hydrochar. Furthermore, the hydrochar's reusability as an adsorbent was investigated, and it was demonstrated that the material continued to function effectively even after four cycles.

Authors: Taramuel-Villacreces James , Pérez-Narváez Hamilton , Rosero-Celi Yessenia
Published: January 2025

La educación superior enfrenta desafíos en la formación integral de los estudiantes en un entorno que exige inteligencia emocional (IE) para manejar situaciones complejas. La IE es esencial para desarrollar habilidades interpersonales, adaptabilidad y manejo del estrés, fundamentales para el éxito personal y profesional. Aunque investigaciones como las de Thorndike y Gardner han explorado la inteligencia social y emocional, no han planteado metodologías específicas para medir la IE en el contexto universitario. Este estudio adopta el modelo multifactorial de IE de Bar-On, que combina habilidades emocionales y sociales para enfrentar presiones ambientales. Con un enfoque cuantitativo y descriptivo, se utilizó el Inventario de Cociente Emocional (EQ-i)-S para evaluar cinco dimensiones clave de la IE en 177 estudiantes de últimos semestres de la Facultad de Filosofía de la Universidad Central del Ecuador, con edades entre 17 y 65 años, de ambos géneros. El coeficiente alfa de Cronbach de 0.75 indica una fiabilidad aceptable. Los resultados mostraron niveles variables de IE, con influencia notable en los ámbitos social, académico y profesional. Se recomienda crear espacios de análisis entre docentes y estudiantes para reflexionar sobre los resultados y trabajar en las áreas problemáticas. Estas iniciativas deben centrarse en desarrollar la autoconciencia emocional, la autorregulación y otras habilidades interpersonales que fortalezcan el desarrollo integral de los estudiantes universitarios.

Authors: Majebi Enesi , Omuya Sefinat , Fagbolu Olukemi
Published: January 2025

The BSc tourism studies programme at the National Open University of Nigeria’s (NOUN) major study centres is experiencing instability in student enrolment. This study examined the attracting and retaining strategies being used by 10 key administrators of the NOUN to boost student enrolment in the programme, using a semi-structured interview technique, based Koch et al.’s student enrolment model. The research participants comprised 6 study centre directors (1 from each of the 6 geopolitical zones of Nigeria), the director of the NOUN’s learners support services, the dean of the faculty where the programme is domiciled, and the head of the programme. Results from the transcribed interviews which were content-analysed based on the student enrolment model and emergent themes show that although the NOUN’s stakeholders are making efforts, including visiting public places with flyers to inform prospective students about the programme, more needs to be done, especially by the host department to boost student enrolment in the programme. Consequently, these findings suggest the need for concerted efforts among the NOUN’s stakeholders to adopt and design measures to help identify and address low student enrolment in the programme, including changing its name to e.g., BSc Tourism and Hospitality Management.

Published: January 2025

Water is the most essential component in daily life. One of its uses is as water in swimming pools. A swimming pool is a public place and facility in the form of a pool building used for swimming. The water used in swimming pools must have a quality that complies with the quality standards determined for the water. One of the parameters required in PERMENKES Nomor 2 Tahun 2023 is the remaining free chlorine. This research aims to analyze the residual free chlorine content in Rinjani Waterpark swimming pool water, where it is known from the results of preliminary studies that Rinjani Waterpark uses chlorine as a disinfectant to kill bacteria in the water and purify the pool water. There were several complaints from swimming pool visitors, such as eye irritation and itchy skin after swimming in that swimming pool, so further analysis was needed. The type of research used in this research is descriptive qualitative. The samples used in this research were 4 samples. The sampling technique uses total sampling. Testing was carried out at the STTL Mataram laboratory to see the free chlorine content in water samples using Mohr's Argentometry method. After conducting the research, the results were obtained that the samples that did not meet the requirements were samples with codes P1 M=2.3 mg/L, P3 M=1.77 mg/L, P4 M=2.3 mg/L, and P3 A = 0 mg/L. Visitors who want to visit the Rinjani Waterpark swimming pool are expected to use personal protective equipment (PPE) such as swimming goggles to avoid the impact of chlorine levels that are too high in the water. Swimming pool managers should pay attention to the chlorine dosage in the water so that it does not cause side effects to visitors.

RECOMPOSIÇÃO DAS APRENDIZAGENS NOS ANOS FINAIS DO ENSINO FUNDAMENTAL: ITINERÁRIOS PEDAGÓGICOS DE LÍNGUA PORTUGUESA PARA O (RE) APRENDER
Authors: Malta Daniela Paula de Lima Nunes
Published: January 2025

O atual contexto pós-pandêmico desempenhou um papel significativo no surgimento e agravamento de desafios enfrentados pelo sistema educacional contemporâneo. A imposição do isolamento social levou à adoção generalizada do ensino remoto, porém esta alternativa revelou-se inadequada para atender às necessidades educacionais em todas as etapas da educação básica. Assim, torna-se imperativa a reconstrução das práticas pedagógicas a fim de proporcionar uma educação mais adaptada às demandas individuais dos aprendizes, incluindo a ressignificação de métodos tradicionais. Neste novo cenário, o estudante assume um papel central como protagonista de seu próprio processo de aprendizagem, enquanto o professor atua como facilitador na consolidação do conhecimento através de atividades interativas e criativas por meio de sequências didáticas, que vão além da mera transmissão de informações. Embora desafiador, este novo modelo de ensino se revela essencial para a construção de uma educação mais inclusiva e igualitária, capaz de atender às diversas necessidades e realidades presentes em nossa sociedade.

Considerando esta premissa o contexto deste estudo, perpassa pela utilização do PDCA na gestão escolar como elemento facilitador dos processos educacionais aliado ao PPP- Projeto Político Pedagógico da Escola. Os desafios educacionais são diários e devem considerar um processo contínuo de planejar, executar, revisar e avaliar a prática. É nesta perspectiva que o delinear deste texto se desenvolve, considerando os processos e dimensões da gestão escolar na construção da educação de qualidade. As exigências, na apresentação de resultados satisfatórios dos processos escolares, tornam imprescindível a condução de ações eficazes na instituição escolar. Assim, a escola deve estar em sintonia com o mundo globalizado e acompanhar os avanços científicos tecnológicos, os quais são necessidades emergentes e indispensáveis às atuais e futuras gerações. Assim destacamos que administrar os processos educacionais aliados aos objetivos da instituição requer o desenvolvimento de processos administrativos bem definidos o que nos leva a referenciar o uso do PDCA na educação com o objetivo de auxiliar as instituições escolares na melhoria do desempenho educacional. A metodologia utilizada foi a revisão bibliográfica. Assim consideramos relevante o uso do PDCA na gestão escolar.

The red devil fish (Amphilophus spp.) is a carnivorous fish from Nicaragua that is considered a pest due to its predatory nature toward smaller fish. Although it does not have high economic value, this fish reproduces rapidly and threatens the endemic fish population in Lake Sentani, Papua. The endemic fish population has declined due to the increasing population of red devil fish that live in colonies in the littoral zone. Despite its high amino acid content, this fish is less favored due to the abundance of bones. One way to increase its consumption is by processing it into crackers. The method used involves training the community. The goal of this activity is to increase the consumption of red devil fish among the community. The results and achievements of this activity show that the women of Yoboi village successfully utilized the previously underutilized red devil fish by processing it into crackers. This has had a positive impact on maximizing local potential and creating new business opportunities, thereby improving economic welfare. This activity has also enhanced food processing skills within the community.

Life expectancy is one of the most popular summary measures for a population's general health. Growing Life Expectancy predicts a rise in senior citizens in the coming years. An increase in health issues among the elderly may result from an aging population. Anthropometric measures of nutritional status can reveal nutritional status, which may contribute to the development of cardiovascular risk; however, research on this topic in the elderly is still lacking. This study uses a cross-sectional design and a sample size of 60 elderly people who live in Muhammadiyah University Palembang's development village. Blood pressure and anthropometric measures were taken by researchers. Throughout the course of five minutes, three separate readings of the blood pressure, waist circumference, mid-upper arm circumference, and body mass index (BMI) were obtained. The means of these measurements were then analyzed. Diastole Blood Pressure/DBP was substantially correlated with BMI, WC, and MUAC (P = 0.001; r = 0.407; P = 0.003; r = 0.381 & P = 0.017; r = 0.307, respectively). In conclusion, systolic and diastolic blood pressure in the elderly are positively associated with anthropometric measures of body fatness, particularly BMI.
