High-Load Operating Characteristics of Planar Membrane Humidifiers of Polymer Electrolyte Membrane Fuel Cell Systems for Heavy-Duty Applications
Authors: Mull Sophie , Weiss Lukas , Wensing Michael
Published: November 2024

To gain high efficiencies and long lifetimes, polymer electrolyte membrane fuel cell systems require precise control of the relative humidity of the cathode supply air. This is usually achieved by the use of membrane humidifiers. These are passive components that transfer the product water of the cathode exhaust air to humidify the supply air. Due to the passive design, controllability is achieved via a bypass. It is possible to use map-based control strategies to avoid the use of humidity sensors. Such map-based control requires deep insights into the humidifier behavior in all possible thermodynamic operating states, including various water loads. This paper focuses on typical operating conditions of heavy-duty application at high load, specifically on the occurrence of liquid water in the cathode exhaust gas, which has not been sufficiently investigated in the literature yet. In order to simulate these conditions, we built a test rig with an optically accessible single-channel set-up of a humidifier. We used a perfluorosulfonic acid membrane without a gas diffusion layer. It was shown that condensed liquid fractions, even isolated droplets, at the cathode outlet significantly enhance the water transfer. The influence of water mass flow rate, pressure level, temperature, and gas flow rate on humidifier’s water transfer rate was investigated. Static and dynamic measurements were obtained, with the presence of droplets also leading to characteristic enhancements in mass transfer during dynamic operation. The analyzed data show that if liquid water is not taken into account: a) the risks of flooding, which lead to irreversible ageing processes and thus to permanent performance loss of the fuel cell are not identified and b) opportunities to improve the membrane humidifier in terms of design, operating strategies and model-based control strategies in heavy-duty applications remain unused.

Authors: C Balamurugan , S Jeno , C Adhikesavan , A Praveen
Published: November 2024

Inadequately designed flow field layouts in bipolar plates within Proton Exchange Membrane fuel cells (PEMFCs) may lead to ineffective water removal and impede reactant transport. This work examines the conventional flow channel designs like that parallel, pinhole, spiral, maze, leaf-like, modified serpentine with two bypass channels, and modified serpentine with four bypass channels in bipolar plates of fuel cells and implements modifications to certain designs to alleviate pressure drops within the flow channels using computational fluid dynamics (CFD) analysis. These designs are optimized by changing different parameters such as size of the channel and rib width utilizing Taguchi L27 standard orthogonal array. The resultant reduction in pressure drop is anticipated to enhance the overall performance of the fuel cell. The optimal flow field design of bipolar plates (Graphite and Aluminum) are manufactured using CNC milling. Tests evaluating surface roughness, contact angle, and corrosion resistance are conducted to assess and compare the performance of these plates. After thorough testing and evaluation, Aluminum showed inferior results compared to Graphite in two key areas: Corrosion rate and Contact angle. Consequently, anodizing was performed on Aluminum to enhance its contact angle and corrosion resistance. The anodized aluminum demonstrated superior performance among the tested materials.

Published: November 2024

The article discusses modern methods of assessing the efficiency of logistics processes, which are one of the most important components of the successful functioning of any company, especially in today's fierce competition and globalization. The article assesses the efficiency of logistics processes, which are an integral part of the company's strategic management and allow ensuring its stable development. The analysis of modern methods for assessing the efficiency of logistics processes in a company has allowed to identify three important tools, such as: data envelopment analysis (DEA), ABC analysis and cost analysis and control method. It is proved that the DEA method can be applied to a wide range of logistics systems, regardless of their complexity and specificity. In addition, DEA allows to identify factors that limit efficiency and develops recommendations for its improvement. The value of ABC analysis is highlighted, which lies in the potential to increase sales volumes by improving the availability of goods that are most valued by customers. An assessment of the efficiency of logistics processes in a company using ABC analysis is proposed. The importance of such a method as cost analysis and control is analyzed. Thanks to a detailed analysis and control of costs, it is possible to identify bottlenecks in the logistics chain, optimize delivery routes, reduce storage costs and increase the efficiency of vehicle use. The author proposes the key stages of the logistics cost analysis based on the “Five Steps” system. It is proved that the joint use of the proposed methods creates synergy, allowing for a deeper and more accurate analysis than when each of them is applied separately. The methods we have studied complement each other, providing company managers with tools for comprehensive analysis and evaluation of logistics efficiency.

MODELING TOURIST ARRIVALS IN THE ISLAND GARDEN CITY OF SAMAL: IMPLICATIONS TO BUSINESS OPERATIONS OF TOURISM-RELATED INDUSTRY
Authors: Asdang Lemuel B. , Murcia John Vianne B. , Schneider Stilo Floyd P.
Published: November 2024

This study aimed to model the tourist arrivals in the Island Garden City of Samal (IGaCoS) by utilizing the autoregressive integrated moving average (ARIMA) method. Specifically, this paper sought to determine whether there was a statistically appropriate forecasting model using the ARIMA approach, based on which it would be possible to reasonably forecast the number of tourist arrivals in IGaCoS. Quantitative secondary data were analyzed by employing the Box-Jenkins ARIMA. The time series plot was characterized by an apparent increasing trend combined with intermittent sinusoidal oscillations. The time series revealed a steady, gradual increase up until 2020. Next, a sharp decline was observed midway through 2020, indicative of the ill effects of the COVID-19 pandemic. A gradual increase was noted once more, starting in 2021, with some fluctuations. The Augmented Dickey-Fuller (ADF) test revealed that the time series was non-stationary at level— but was made stationary after differenced twice. The ARIMA (1,2,1) model was found to be statistically significant. The fitted model initially showed some notable deviations from the original data, but, with time, converged closely to the actual values, proving it is a reliable way to represent underlying patterns. The ARIMA (1,2,1) model, selected for having the lowest AIC and BIC values and a MAPE within the acceptable range for reasonable forecasting, was used to predict tourist arrivals in IGaCoS over the next six months. The forecasted values suggested a mix of fluctuations and stability. There was a noticeable upward trajectory at the beginning, which was followed by a slight decline at the end that yet remained stable. The forecasted results from the ARIMA (1,2,1) model may provide businesses with a roadmap for comprehensive planning in terms of operational and strategic concerns. This study helped address Sustainable Development Goal (SDG) No. 8, Decent Work and Economic Growth.

CURRENT SITUATION AND CHALLENGES IN EFL TEACHER EDUCATION IN THE EUROPEAN UNION WITH RESPECT TO GENDER AND SEXUAL-AFFECTIVE DIVERSITY
Authors: Muñoz-Martín Lucía , Barros-del Río María Amor , Sigona Concetta Maria
Published: November 2024

Gender identity and sexual diversity remain significant sources of discrimination in the 21st century, exacerbated by pervasive androcentrism, cisnormativity, and heteronormativity. In the context of the European Union (EU), education is critical for fostering social cohesion among an increasingly multicultural population due to migration and mobility. Initial Language Teacher Education (ILTE) plays a pivotal role in preparing future educators to instill values of diversity, inclusion, and interculturality. Despite the EU's efforts to unify educational frameworks through programs like Erasmus+ and initiatives such as the European Language Portfolio, discrepancies persist across member states regarding language teacher training curricula. These variations hinder the broader aim of creating an inclusive, cohesive educational system grounded in human rights and equality, particularly concerning gender and sexual diversity. This paper explores the challenges and proposes the need for a unified ILTE training that integrates the principles of inclusivity, social diversity, and respect for all identities.

Therefore, innovative and friendly strategies to develop learners’ retention of physics have been a matter of concern over the years. This study, therefore, strives to investigate the power of video-based multimedia (VBM) to nurture and promote learners’ retention in astrophysics in selected schools in Rwanda. 294 students were purposively selected for the scientific option with physics as a major subject in Rutsiro and Rubavu districts. The astrophysics achievement test with Cronbach alpha 0.87 was used to collect data within the pre/post-test non-equivalent control group quasi-experiment research design. The output revealed that the VBM intervention group outperformed the usual teaching control group. The results also showed that females retained marginally more than males in VBM intervention classes, and urban students retained better than their rural counterparts. Based on the output of this study, we concluded that credit goes to VBM as a friendly and innovative teaching method. Hence, we recommend using VBM in teaching and learning physics with special attention in rural-based schools.

AN ASSESSMENT OF THE PARENTAL INVOLVEMENT CONTRIBUTION ON THE PRIMARY SCHOOLS’ ACADEMIC PERFORMANCE IN TANZANIA
Authors: Godson Leonard , Gwambene Brown , Mwahombela Lucas
Published: November 2024

Parental involvement is very important in student’s learning and academic progress in primary schools. However, the combined impact of various factors, including poverty, illiteracy in some families, lack of time, language, and lack of knowledge about the curriculum, especially among the parents, makes their effective involvement in their children’s education challenging. This study utilized the social capital theory developed by Pierre Bourdieu and the community participation theory by Sherry Arnstein to have a clear understanding of the study. The combination of the two theories provided an understanding of parental involvement in primary school education in the study area. The study employed a descriptive research design that used both qualitative and quantitative approaches. The targeted population consisted of public primary school students, teachers, head teachers, ward education officers, and school-going students' parents. Questionnaires, interview guides and documentary reviews were used to collect information about parental involvement in public primary schools. Qualitative data was analyzed mainly through thematic analysis, and SPSS software was used to analyze the quantitative data. Simple statistics have been presented in tables and figures to depict the frequencies, percentages and means in relation to the findings of the study. The study found that parental involvement contributes much to the lives of schools. Without it, it could be hard to run the school’s activities. This is because the schools are better managed through the collective efforts of both teachers and parents, as well as other educational stakeholders in the community. Therefore, the government should educate parents about the necessity of their involvement in schools so as to be ready to take responsibility for supporting their children in different ways.

REVIEW OF INTEGRATING TAI CHI INTO ACADEMIC CURRICULUMS: IDENTIFYING ITS LIMITATIONS AND CHALLENGES IN IMPLEMENTATION
Authors: Nkemeni Darrin Sime , Hong Hao
Published: November 2024

This paper explores the declining interest in Tai Chi among younger demographics, identifying several core issues. The prevalent stereotype that associates Tai Chi primarily with the elderly diminishes its appeal to younger audiences, as its slow, meditative movements lack the excitement found in traditional martial arts. Furthermore, conventional teaching methods often prioritize rigid form and theory over interactive, engaging practices. In an age dominated by digital distractions, activities without immediate gratification struggle to attract attention, with many students gravitating towards high-energy sports that promise quick results. Innovative teaching strategies are essential to rejuvenating interest in Tai Chi. By integrating modern fitness trends, utilizing technology such as apps or virtual trainers, and emphasizing the mental health benefits of Tai Chi, its attractiveness can be significantly enhanced. Developing a dynamic curriculum that balances theoretical understanding with practical application while including interactive elements can deepen student engagement. Additionally, highlighting Tai Chi's versatility and real-world applications can pique interest, as can combating stereotypes through the promotion of young, charismatic practitioners on social media platforms. The proposed strategies aim to reposition Tai Chi as a relevant and appealing practice for today’s youth, fostering a new generation of practitioners.

Press releases are essential in public relations for announcing newsworthy items, such as product launches, quarterly earnings, mergers, or important updates. As in various fields, digitalisation has changed and transformed some tools and methods in public relations. However, press releases, one of the oldest public relations tools, are still used by organisations' communication departments for the same purposes. Due to digitalisation, press releases are now posted on businesses' websites and social media pages. For this reason, the press releases published by the four airlines on their corporate websites were analysed in this study. The main objective of the research is to identify the message content in press releases and how it aligns with public relations objectives. For this purpose, all press releases issued by four airline companies in 2023 were analysed using content analysis. In this context, it was determined that airline companies issued press releases in a total of nine different categories. These categories are press releases named Public Announcement, New Route, Corporate Social Responsibility, Financial - Earnings, Innovation & Technology, New Partnership, Award Announcement, Product - Service Launch, and Sponsorship. As a result, it was concluded that these press releases also serve airlines' marketing and public relations purposes.
