Model-Based Algorithm for Water Management Diagnosis and Control of PEMFC Systems for Motive Applications
Authors: Sicilia Massimo , Cervone Davide , Polverino Pierpaolo , Pianese Cesare
Published: June 2024

Water management in PEMFC power generation systems is a key point to guarantee optimal performances and durability. It is known that a poor water management has a direct impact on PEMFC voltage, both in drying and flooding conditions: furthermore, water management entails phenomena from micro-scale, i.e., formation and water transport within membrane, to meso-scale, i.e., water capillary transport inside the GDL, up to the macro-scale, i.e., water droplet formation and removal from the GFC. Water transport mechanisms through the membrane are well known in literature, but typically a high computational burden is requested for their proper simulation. To deal with this issue, the authors have developed an analytical model for the water membrane content simulation as function of stack temperature and current density, for fast on-board monitoring and control purposes, with good fit with literature data. The water flow from the catalyst layer to the GFC through the GDL is modelled considering as main transport mechanism the capillary transport. The water coming from the GDL then emerges through the pores inside the channel forming water droplets that interact with the air flow. The authors have developed several papers on this topic: mathematical models have been developed for droplet’s emersion, oscillation, and detachment phases; furthermore, the coalescence between near droplets has been included into the modelling. The authors have also validated with experimental results the proposed models. The objective of this paper is to develop a mathematical model able to represent a typical fuel cell stack in order to predict the water membrane content and the water removal rate, that are fundamental to correctly control the PEMFC system in order to avoid the critical conditions mentioned before, ensuring the best performances of the stack reducing the hydrogen consumption. The model is validated with literature data, showing optimal fit and high correlation, making it suitable for further analyses.

Authors: Dalpadulo Enrico , Russo Mario , Gherardini Francesco , Leali Francesco
Published: June 2024

Composite materials, pioneered by aerospace engineering due to their lightness, strength, and durability properties, are increasingly adopted in the high-performance automotive sector. Besides the acknowledged composite components’ performance, enabled lightweighting is becoming even more crucial for energy efficiency, and therefore emissions along vehicle use phase from a decarbonization perspective. However, their use entails energy-intensive and polluting processes involved in the production of raw materials, manufacturing processes, and particularly their end-of-life disposal. Carbon footprint is the established indicator to assess the environmental impact of climate-changing factors on products or services. Research on different carbon footprint sources reduction is increasing, and even the European Composites Industry Association is demanding the development of specific Design for Sustainability approaches. This paper analyzes the early strategies for providing low-carbon aerospace and automotive composite components by design. The goal is to enable design approaches that consider the material life cycle from product and process design, material selection and fabrication, to eventual recycling and reuse. The investigation includes the design approaches and tools, and the aspects concerning ultimate trends of materials development, shapes generation, and manufacturing processes. Among these, we discuss the potential role of emerging technologies such as digital intelligence, Biocomposites, biomimicry, generative AI, and additive manufacturing. The aim is to identify the framework of possible drivers for Design for Sustainability approaches, rethinking lightweight products lifecycles and highlighting the resulting challenges and future developments. Moreover, as practical examples, a few innovative cases are provided to prove the effective potentials of such guidelines. The conclusive remarks discuss the advantages and disadvantages of the design drivers and the need for assessment and validation through vehicle Life Cycle Assessment approaches.

Published: June 2024

In this era, social media has brought significant changes in the way businesses communicate and share information with consumers. This makes it easier for potential customers to obtain information as a decision-making flow. One natural tourism destination that recognizes the value of Instagram advertising is Woodland. Woodland has gained significant marketing attention as one of the natural tourist attractions. The reason for choosing this research object stems from the noteworthy progress of several marketing tactics, including digital-based promotion and brand revitalization, after the challenging 2019-2020 era in Woodland (caused by the COVID-19 epidemic), as a result of this noteworthy progress, there were 53.02% more visitors in 2022. This study used quantitative techniques. The t-table values obtained show that social media advertisements significantly influence the intention to visit woodland tourist attractions. The study's findings, which showed that Ha was approved while Ho was rejected, lend support to this claim. In addition, attractiveness significantly and positively affects the tendency of tourists to visit places that have forests. Visit intent is also influenced by social media attraction and advertising. Specifically, social media will create expectations for a destination so that it allows potential tourists to determine their vacation plans. Therefore, business people and related agencies must be able to pay more attention to the long-term management of social media and the attractiveness of their tourist destinations.

Outra particularidade do evangelho segundo João é a realidade dos Sinais, que ganham grande relevância em se tratando da revelação do Pai por e em Jesus. O presente artigo tem a intenção de sinalizar a eminência da Hora Gloriosa de Jesus já na unção acontecida em Betânia por parte de, segundo João, Maria irmã de Lázaro, e alguns significados que tal unção sinaliza, isto é, ver a unção de Betânia como Sinal da Hora.
Domine, quo vadis?
Authors: Cordeiro Santos Lucas
Published: June 2024

Muitas ações e imagens retratam de maneira expressiva o pontificado do Papa Francisco, seja sua personalidade, suas escolhas, seus exemplos e atitudes, entretanto, desde o início de seu pontificado, a exatos 10 anos, o discernimento e o discipulado mostraram-se o eixo central de sua ação pastoral. Diante desta constatação, este artigo busca evidenciar a importância do discernimento no pontificado de Francisco a partir das catequeses sobre o discernimento, pronunciadas entre agosto de 2022 e janeiro de 2023 e a Exortação Apostólica Evangelii Gaudium. Ilustrando e dialogando com esta questão estará o tema do discipulado no evangelho de Marcos. A literatura marcana expõe uma trajetória muito particular da formação dos discípulos que gradativamente delineiam a identidade de Jesus. Entre avanços e retrocessos eles discernem a missão de Jesus. A partir deste diálogo entre Sagradas Escrituras e Magistério o artigo confirma a ideia de que o discernimento é a alma do discípulo que aceitando sua vulnerabilidade não desiste de colocar-se atrás de Jesus e segui-lo. Francisco, em seu pontificado, readmite esta mesma interpretação para a Igreja e confirma que é necessário discernir para onde o Senhor envia seus discípulos e missionários contemporâneos.
WHAT CONTRIBUTES TO BETTER OVERALL EVALUATIONS WHEN APPLYING FOR A JOB? SOCIABILITY OR COMPETENCE? THE ROLES OF TRAIT AND WORK SETTING IN GAINING POSITIVE OVERALL EVALUATIONS
Authors: Jijyan Hovhannes
Published: June 2024

Job candidate evaluation is relevant for any organization, however the factors which lead to positive evaluations have been argued upon by researchers, mainly stating their differing opinions on the context of the job and the climate of the organization. This paper investigates whether trait and setting have an impact on candidate evaluation, and if they do, which factor has the most influence. The study used a 2x2 experimental between-subjects design, with overall evaluation as the measured variable. Trait was measured through sociability and competence. Setting was defined as either working from home or at the company office. The hypotheses of the paper were the following; Candidates scoring higher on sociability will receive more positive overall evaluations, this relationship will be stronger for those candidates who are expected to work physically from the office. 267 participants completed a questionnaire assessing their decision in hiring a candidate who is high in sociability or competence, while also including the job setting as an influencing factor in this model. After analyzing the data, it was found that sociability does in fact lead to more positive overall evaluations. The results led to the conclusion, that the candidate who was more sociable rather than competent was chosen by raters. Setting did not have a significant interaction effect with trait, concluding that working remotely, or at the company office does not affect the respondent’s choice on preferring sociability over competence in a potential candidate.

Authors: Mahmoud Ashawesh  , Sara Alashhab  , Sakena Kori
Published: June 2024

Background and objectives: Disinfectants and antiseptics are widely used in hospitals and other healthcare centers to ensure the prevention of nosocomial infections and provide efficient infection control. Numerous studies have recently shown that hospital-acquired bacteria are developing resistance against such compounds. The purpose of this study is to examine the effectiveness of the commonly used disinfectants and antiseptics against a group of nosocomial bacteria isolated from Tripoli University Hospital, Libya. Material and Methods: Five bacterial pathogens isolated from different hospital departments are klebsiella spp., Proteus spp., Escherichia coli (E. coli), Acinetobacter spp., Staphylococcus aureus (S. aureus). These isolated bacterial species were subjected to disinfectants and antiseptics impregnated with filter paper discs (disk diffusion assay). The disinfectants and antiseptics used were; Hydrogen peroxide (H2O2), OROLIN® Multisept plus (Orolin), Chlorhexidine (CHX), 84 Disinfectant, ACTOSAL® Flache AF (Actosal) and Ethyl alcohol. Results: In the present study found that the most effective was H2O2 antiseptic against the tested bacterial pathogens with inhibition diameters of 10 to 26mm, except for Proteus bacteria which illustrated resistance at high concentrations. Similarly, Orolin disinfectant shows very excellent efficacy against tested bacteria, and even with low concentrations. Good efficacy was observed for Actosal disinfectant on all species with diameters of inhibition ranging from 10 to 15mm. S. aureus in particular was very sensitive to 70% Ethyl alcohol (20mm), while all tested species were slightly insensitive to both Ethyl alcohol and CHX. In contrast, no effect of the 84 disinfectant was observed on most of isolates. Conclusion: The results of this study indicated that Orolin disinfectant had comparable effects to H2O2 atiseptic but less than to Actosal, 70% Ethyl alcohol and CHX, whereas 84 disinfectant was the weakest one. This study suggests the necessity of applying continuous monitoring to determine the antimicrobial efficacy of these antimicrobial agents regularly.

Published: June 2024

Все больше внимание уделяется способам передачи информации между морскими исследовательскими приборами и пунктами сбора и обработки информации для дальнейшего анализа и выработки концепций развития Мирового океана. Вся передаваемая информация подвержена получению третьими лицами, в связи с этим, стоит одна из задач, защита передаваемой информации. Не исключение составляет и организованный канал передачи информации между морской платформой и берегом на Черноморском гидрофизическом подспутниковом полигоне. Представленная математическая модель на основе метода стеганографии позволяет решить задачу подтверждения подлинности путем внедрения дополнительной информации в исходный сигнал, таким образом, что факт внедрения не будет распознан эмпирически. Одним из первых и наиболее известным методом скрытного внедрения дополнительной информации является метод на основе технологии расширения спектра и множественные его модификации, основанные на внедрении в математическую формулу дополнительных коэффициентов, призванных усовершенствовать метод. Однако, при кодировании дополнительной информации введение в исходный звуковой сигнал коэффициентов оказывает влияние на скрытность и изменяет устойчивость, что может привести к разрушению стегосистемы. Поэтому совершенствование методов стеганографии, с одной стороны, направлено на повышение скрытности, а с другой стороны, на повышение стойкости.

Published: June 2024

According to recent data, many communities worldwide are multicultural nowadays. Culture is believed to significantly impact the creation of therapy materials, practice models, assessment instruments, and client collaboration. Also, recent works address the interaction between a therapist and a client and the need to understand a child's social needs. Even with significant advancements in the development and delivery of efficient treatments for children with ADHD, ethnic minority youths and teens continue to lag behind their non-minority peers in terms of diagnosis and treatment rates. Various learning and behavioral obstacles are linked to this disorder because of cognitive and metacognitive functioning difficulties. Individuals can only fully integrate into society if these functions have been acquired. Children can acquire alternate strategies to manage their cognitive deficits and adapt to different circumstances by using internal attention to build self-awareness, self-regulation, and self-control. The quick progress of research has led to the development of several medicinal and psychological strategies for treating ADHD, which significantly help with symptom management. The goal of the current study is to gain an understanding of the various therapeutic approaches used to help children from racial and ethnic minorities who are suffering from ADHD. These approaches include games using augmented reality (AR) environments.

Published: June 2024

Çalışmada XU100 endeksi bazındaki yerli ve yabancı yatırımcıların XU100 endeksinin etkinliğine olan etkisinin araştırılması amaçlanmaktadır. Çalışmada ilk olarak Sample Entropi kullanılarak XU100 endeksinin bilgisel etkinlik seviyesi hesaplanmıştır. İkinci olarak Fourier Otoregresif Gecikmesi Dağıtılmış eşbütünleşme testi (FADL) ile yerli ve yabancı yatırımcıların portföy değerlerinin etkinlik üzerindeki etkisi araştırılmıştır. Bulgular, XU100’ün kısmı etkin olduğunu göstermektedir. Covid-19 Dönemininden itibaren XU100, etkinlik seviyesinin en düşük olduğu zamanları yaşamakta olup, XU100’ün etkinliği pandemi öncesi seviyelere ulaşamamıştır. FADL test sonuçları ise yerli ve yabancı yatırımcıların portföy değerleri ile XU100 endeksinin etkinliği arasında uzun dönemli ilişki olduğu yönündedir. Elde edilen bulgular, yabancı yatırımcıların XU100 endeksinin etkinliğini pozitif yönde, yerli yatırımcıların ise negatif yönde etkilediğini göstermektedir. Bu sonuçlar, yabancı yatırımcıların kurumsal yatırımcılardan oluşması ve bu yatırımcıların uluslararası piyasalarda işlem yapmaları nedeniyle üstün yatırım deneyimlerine ve bilgiyi daha iyi işleme konusundaki tecrübelerine sahip olması olarak açıklanabilir. Yerli yatırımcılarda ise davranışsal faktörlerin piyasa etkinliği üzerinde etkili olduğunu göstermektedir.
Understanding of Connectivity and Interlinkages between Human Activities and Climate Change: Community Perspectives from Kenya
Authors: Kibue G.W , Kirui K.B
Published: June 2024

Purpose: This study was conducted in Nakuru County, Kenya and aimed at assessing the community knowledge of the complex interrelationship between individual and collective activities and climate change in Kenya. Specifically, we assessed the knowledge and perception of climate change, grassroot information flow on Greenhouse Gas (GHGs) and climate change, and local practices/activities taken towards mitigation/adaptation to climate change.
Methodology:  The study involved both qualitative and quantitative research methods. Data was collected using literature reviews, questionnaires, focus group discussions, and key informant interviews.  Descriptive analysis was used to summarize data that were then presented as frequencies and percentages. Index construction was undertaken by summing up the scores for all statements relating to knowledge and perceptions to obtain a single group of variables. Chi-square tests were used to test relationship between variables. 
Findings: Eighty (80%) of the respondents indicated that climate change is real, 69% of which attributed it to human activities, majorly (52%), clearance of vegetation. Most of the respondents (63%) had no idea about any climate change policy in the county while barely half (48%) could identify at least 1 greenhouse gas. This points to a gap in knowledge transmission from the national/County to the community and perhaps lack of sufficient community involvement in policy making. It was further established that there was a disconnect in information flow from scientific sources to communities that most respondents (63%) obtained climate information from community groups while only 2% relied on scientific sources, which would provide accurate information. this implies that the respondents may not be employing climate change mitigation strategies in their everyday interventions. Gender and education had significant influence on awareness and attitude towards climate change.

Este artigo trata-se de um ensaio teórico, cujo objetivo foi analisar a formação nos cursos de licenciatura. Para responder às perguntas apresentadas desenvolveu-se pesquisa qualitativa de caráter bibliográfico e documental. Ademais, utilizaram-se artigos e livros de autores que discutem a formação inicial, como Gonçalves (2000), Tardif e Lessard (2005), Costa (2009), entre outras obras pertinentes sobre o tema. Diante das discussões, elencaram-se muitas fragilidades na formação do professor de matemática, em razão disso, percebe-se a importância da construção de melhorias na formação profissional. Por fim, considera-se necessário inserir na formação do professor o desenvolvimento de projetos que visem solucionar as dificuldades oriundas do ensino básico, a partir da inclusão de atividades, palestras e rodas de conversas que evidenciem as dificuldades vivenciadas na sala de aula, entre outras possibilidades.
Evaluating the Transportation Sector of Siargao Island: Basis for a Proposed Online Payment System with QR Code Technology
Authors: Argie E. Libay  , Riah E. Encarnacion
Published: June 2024

The rapid growth of tourism in Siargao Island continues to outpace its transportation sector resulting to inefficiencies and security concerns stemming from cash transactions. Tourists face challenges such as fare inconsistencies, limited payment options, and safety concerns due to the reliance on cash transactions, making the current system cumbersome and risky for all parties involved. This study aims to evaluate the current transportation sector and propose "e-Bayad" application, a QR code-based online payment system, to enhance convenience, efficiency, and security for tourists and service providers. A mixed-methods approach was employed, combining quantitative data from surveys and qualitative insights from interviews to understand the transportation challenges and user preferences. The respondents have a high level of agreement in terms of the lack of transparency in fare collection procedures (WM = 4.21), overcharging of fare by transportation providers (WM = 4.17), and inconsistency in fare charges among different transportation modes (WM = 4.14).The study also identified significant points, including fare-related issues, payment difficulties, and security concerns, leading to the proposal of the "e-Bayad" system, an online payment system. This system offers QR code payments that streamlines transactions and improves transparency to address these challenges. The development and implementation of "e-Bayad" has the potential to transform the transportation payments in Siargao. It can significantly improve the overall transportation experience for both tourists and locals and contributing to the sustainable growth of the island's tourism industry

The study was carried out to identify through scientific methods the active ingredients and the pharmacological activities of the shoot and root extracts of Mimosa pudica Linn. The Mimosa pudica shoot methanolic extract (MSME),Mimosa pudica root methanolic extract (MRME) showed very good wound healing activity when compared to the standard drug Gentamicin. Tridax procumbens L. (Compositae) is a common weed that grows in the rice fields of India. Traditionally the juice from leaves of Tridax procumbens has been used for healing dermal wound. However, in experimental studies, equivocal pro and anti-healing action of T. Procumbens has been demonstrated. It has been studied previously that stage of wound healing involves acute inflammatory phase followed by the synthesis of collagen and other extra cellular macromolecules, which is later removed to form a scar
