Композит на основе графитоподобного нитрида углерода и легированного магнитными ионами феррита иттрия является перспективным фотокатализатором таких энергетически затратных реакций, как разложение воды с получением водорода. Использование данной системы позволяет обеспечить эффективное разделение зарядов и отличительную эффективность к абсорбции света. Известно, что на фотокаталитическую активность влияют такие параметры, как ширина запрещенной зоны, удельная поверхность и кристалличность. Получение композитов на основе графитоподобного нитрида углерода выгодно не только с точки зрения улучшения вышеперечисленных параметров, но и для придания системе дополнительных свойств, например, магнитных за счет легирования магнитным ионом эрбия Er3+. Проведенное исследование показывает увеличение способности к намагничиванию и снижение величины ширины запрещенной зоны композита с 2,70 до 2,55 эВ с увеличением степени замещения феррита магнитным ионом Er3+, что подтверждает выдвинутые гипотезы.

Published: November 2024

Neste artigo realizamos uma revisão da literatura acerca de como os conceitos de Perfil Conceitual, proposto por Eduardo Mortimer, e Perfil Epistemológico, desenvolvido por Gaston Bachelard, estão sendo utilizados pela comunidade do Ensino de Ciências. Em sua gênese, o Perfil Epistemológico caracterizou as zonas filosóficas do conhecimento científico e suas transformações, enquanto o Perfil Conceitual focou na evolução das ideias e na interação com o contexto social e cultural. As diferenças entre as proposições desses perfis e seus empregos nas pesquisas revisadas revelaram tensões teóricas e metodológicas, principalmente na relação entre epistemologia e pedagogia. De tais elementos, emerge a ideia de que, em certa medida, o uso desses conceitos tem sido desenvolvido com alguns abusos e confusões, “ruídos” que o presente texto busca problematizar.

Authors: Larios-Ulloa Mauricio , Ramírez-Muñoz David
Published: November 2024

Los residuos del tequila y el mezcal son un problema al no tener un manejo adecuado, por ello se utilizaron bagazos de tres especies de agave (A. tequilana, A. angustifolia y A. salmiana) como sustrato para el cultivo del hongo P. ostreatus, como propuesta de valor agregado al bagazo y evitar tiraderos clandestinos y contaminación. La investigación se llevo a cabo en el Centro Universitario de los Lagos, en Lagos de Moreno, Jalisco en el año 2019. Se realizaron mezclas de cada uno de los sustratos con estiércol bovino o rastrojo de maíz, ambos en proporciones de 20 y 30%, adicional a estas mezclas se realizó otro sustrato 50% de A. angustifolia más 50% A. salmiana, en total 16 modelos experimentales y un control (100% rastrojo de maíz), todos por cuadruplicado, con el objetivo de determinar qué mezcla puede generar mejor eficiencia biológica (EB), tasa de producción (TP) y rendimiento (Re). La eficacia se obtuvo al comparar las medidas morfológicas del cuerpo fructífero: largo y ancho del píleo, largo y diámetro del pie y el porcentaje de capacidad de degradación de los sustratos al medir la tasa de biodegradación (TB). Se observó una mejoría en la EB, TP y Re para A. salmiana y A. angustifolia. A. tequilana no alcanzó mejoría al realizar la mezcla con rastrojo de maíz o estiércol en comparación con el uso único de A. tequilana. Por lo cual la utilización del bagazo de Agave spp. es adecuado para el cultivo de P. ostreatus al alcanzar una eficiencia biológica mediana que puede mejorar al adicionar nitrógeno, esto permite darle un uso al bagazo y evitar su acumulación en vertederos contaminantes.

“Is It Suicide or Genocide?”: Black Female Clinicians’ Critical Understandings of Shame and Other Related Themes to Suicide in Black Communities
Authors: Hightower Heath H.
Published: November 2024

Suicide is a complex, multi-factorial human experience that affects millions of people in the U.S. and disproportionately impacts Black communities every year. Historical data, critical theories, and research literature indicate that Black suicides result from interactions between macrosystemic systemic forces and individual-level meaning-making processes. To explore the complexities among systemic forces and deaths often labelled suicides in contemporary U.S. Black communities, this project centered and elevated the critical perspectives of fourteen Black female clinicians. Because of their marginalized identities, intersectional lived experiences, and clinical training, these participants were well-positioned to analyze and understand the degrees to which suicides in Black communities are associated with oppressive macrosystemic dynamics and/or individual-level psychological factors. Narrative inquiry and thematic analysis underscored the interplay among six thematic characters for critically understanding suicide in Black communities: shame, hopelessness, trauma, racism, systemic problems, and fear. Participants also noted that violence, anger, and guilt shaped their perspectives to a lesser degree. To address these themes’ suicide-potentiating effects on Black communities, I discuss language, research, policy, and psychosocial assessment and intervention implications.
Utilization of virtual reality as a learning tool to increase students’ pro-environmental behavior at universities: A maximum likelihood estimation approach
Authors: Sahabuddin Erma Suryani , Makkasau Andi
Published: November 2024

This research explores the effect of virtual reality technology on enhancing university students’ environmental knowledge (ENK), environmental attitudes (ENAs), and pro-environmental behaviors (PEBs). The primary objective is to evaluate how immersive virtual reality (VR) experiences influence students’ understanding of pressing environmental issues like climate change, deforestation, and pollution. A sample of 336 students from Universitas Negeri Makassar who participated in a VR-based environmental education class were surveyed through structured questionnaires distributed via Google Forms. Stratified random sampling was employed to ensure a diverse illustration of the student population. The study applies covariance-based structural equation modeling using the AMOS program to evaluate the correlations among the variables of ENK, attitudes, and behaviors. The results indicate that VR significantly enhances students’ ENK by providing an interactive and immersive learning platform that simplifies complex ecological concepts. VR was shown to positively influence students’ ENAs by simulating real-world environmental degradation consequences, fostering emotional connection and concern. A robust link was also identified between improved ENAs and increased PEBs, such as waste reduction and energy saving. These findings demonstrate that VR can be an actual tool for driving behavioral change in the context of environmental education, offering a promising approach to addressing global sustainability challenges. The analysis adds to the expanding body of literature on technology-enhanced learning, highlighting the potential of VR to promote sustainability through education and fostering a more profound commitment to environmental stewardship among students.

Authors: Syed Ismail Syed Azman , Maat Siti Mistima , Khalid Fariza
Published: November 2024

Fraction learning is a fundamental yet challenging component of mathematical education, critical to students’ broader mathematical development. This study presents a comprehensive review of fraction learning research spanning the years 1989 to 2024, integrating a systematic literature review with bibliometric analysis to explore the evolution, trends and gaps in this domain. Utilizing data from the Web of Science database, we reviewed 725 articles, identifying key themes through co-citation analysis and categorizing the literature into three primary clusters: cognitive and conceptual understanding of fractions, developmental and educational aspects of fraction learning and teacher knowledge and its impact on mathematics teaching. Our findings reveal a shift from early research focused on conceptual foundations to more recent studies emphasizing educational interventions and teacher preparation. The analysis also highlights significant geographical imbalances, with most research originating from Western countries, particularly the USA. Despite advancements, critical gaps remain, particularly concerning the long-term retention of fraction knowledge and the effectiveness of adaptive learning strategies. This study underscores the importance of a multifaceted approach to improving fraction learning outcomes and calls for future research that addresses these gaps, particularly in diverse educational contexts. The findings provide valuable insights for educators, policymakers and researchers, guiding future efforts to enhance fraction education globally.
Exploración del potencial catalítico de metal-organic frameworks con sitios de coordinación insaturados en síntesis orgánica.
Authors:   , Báez Gómez Reynier
Published: November 2024

En los últimos años, los Metal-Organic Frameworks (MOFs) han ganado relevancia en diversas aplicaciones, destacándose en la catálisis heterogénea debido a sus propiedades únicas, como una alta porosidad y superficie específica, estabilidad térmica, y la capacidad de incorporar centros catalíticamente activos.
En este trabajo se realizó la síntesis, caracterización y evaluación catalítica de cuatro MOFs: HKUST-1, MIL-101(Cr), UiO-66-NH2, y MIL-53(Al). Destaca la síntesis de MIL-53(Al) mediante reciclaje ascendente (up-cycling) a partir de latas de aluminio y botellas de PET, lo que promueve la economía circular al demostrar la viabilidad de producir MOFs a partir de residuos. Los MOFs fueron evaluados como catalizadores heterogéneos en dos reacciones de formación de enlaces C-N. Se reporta por primera vez el uso de MOFs como catalizadores en la síntesis de hidracidas a partir de aldehídos y azocompuestos. La reacción se llevó a cabo a 60 °C durante 48 horas en acetato de etilo, obteniéndose 16 compuestos con rendimientos entre 54 % y 97 %. También se estudió la síntesis de pirroles mediante la reacción de Paal-Knorr a partir de anilinas y acetonilacetona. La reacción se llevó a cabo en condiciones libres de solventes utilizando irradiación de microondas durante 5 minutos, produciendo 7 pirroles con rendimientos entre 50 % y 96 %. En ambas reacciones, MIL-53(Al) demostró ser el catalizador más eficiente, con un contenido MOF de 10 mol % y 5 mol %, respectivamente. Además, se evaluó la estabilidad y reutilización de MIL-53(Al) durante cuatro ciclos catalíticos consecutivos, manteniendo su rendimiento con una disminución mínima.
La combinación de alta actividad catalítica, estabilidad y origen sostenible del MIL-53(Al) representa un avance significativo en la catálisis heterogénea y la química verde. La aplicación pionera de MOFs en la síntesis de hidracidas amplía las fronteras de la catálisis con estos materiales, proporcionando un ejemplo claro de cómo los principios de la economía circular y la innovación en catálisis pueden aplicarse en la síntesis de materiales avanzados y en el desarrollo de procesos químicos más eficientes y ambientalmente amigables.

Published: November 2024

La salmonicultura es una actividad que impacta los sedimentos a través de los residuos de la alimentación. Los microorganismos juegan un rol fundamental en el reciclaje de la materia orgánica; sin embargo, el efecto de la salmonicultura sobre la composición microbiana aún es poco conocido. En particular, Piscirickettsia salmonis es una bacteria patógena presente en los cultivos durante largo tiempo en Chile. En este trabajo se estudiaron las comunidades microbianas asociadas al sedimento (metagenómica) y particularmente P. salmonis (qPCR), ya que el sedimento podría ser un posible reservorio. Así también, se determinaron los parámetros fisicoquímicos del sedimento (C, N, P, Redox y Materia Orgánica Total), en el área de estudio del fiordo Puyuhuapi. El programa de muestreo fue desde el inicio del periodo productivo (primavera 2022) hasta el otoño 2023. Se obtuvieron muestras en un gradiente desde las balsas jaulas de un centro productivo y hasta 7 kilómetros distante de él. Los resultados demuestran que existe un incremento significativo (p 0,05), en la concentración de C, N, P y Redox, en los sedimentos a través del tiempo y una correlación significativa (p 0,05) de estos parámetros con la señal molecular (Log) de la presencia de P. salmonis. Así también, se observó un incremento de la diversidad de bacterias asociadas a la degradación anaeróbica de materia orgánica bajo la balsa jaula. Finalmente se determinó un incremento de la señal molecular de P. salmonis en los sedimentos del área de estudio a través del tiempo, siendo este el primer indicio de que esta matriz ambiental pudiese actuar como un reservorio, asociado al proceso productivo de la cría de salmón.

Published: November 2024

Automatic speech recognition is a process of using computers to convert voice signals produced by human speech into reasonable format i.e. text or command that conveys the same meaning as the speaker intended to do. Many researchers are working on various languages including English and other European languages like Spanish, German, and French etc. to develop an automated system for speech recognition (ASR). However, researchers on the development of ASR for the Urdu language have put very little effort. We have developed an Urdu speech recognition system using Deep Neural Network (DNN) on our developed corpus that contains some of the most frequently used words in Urdu like digits, season names, and month names. The accuracy rates of our ASR are very encouraging because 72% accuracy is achieved for 26 words and 92% accuracy is achieved separately for names of seasons.
A Comparative Analysis of Twelve Research Paradigms Across Six Knowledge Acquisitions and Twelve Sources of Knowledge: A Philosophical Discourse
Authors: Tambun A.R.Y. Toronata , Yudoko Gatot , Aldianto Leo
Published: November 2024

This study investigates whether a single research paradigm can dominate knowledge acquisition across empirical and interpretive domains or if a multi-paradigm approach is essential for achieving a holistic understanding. Twelve paradigms, including Positivism, Pragmatism, Hermeneutics, and Feminism, were evaluated across six domains: Science, Philosophy, History, Art, Religion, and Culture. The methodology employed comparative analysis, factor analysis, sensitivity testing, and inter-rater reliability assessment to quantify paradigm performance. The findings confirm Positivism's strength in empirical fields like Science and Philosophy but reveal its limitations in addressing ethical, cultural, and interpretive dimensions, where paradigms like Hermeneutics and Feminism excel. Pragmatism and Critical Realism bridge empirical rigor with interpretive depth, offering integrative solutions for interdisciplinary challenges. By applying statistical tools within a philosophical inquiry, this research highlights the necessity of humility and open-mindedness in selecting paradigms to address complex questions. The study concludes that no single paradigm suffices across all domains, advocating for a multi-paradigm approach to foster collaboration, inclusivity, and a more comprehensive understanding of knowledge production. These insights have implications for interdisciplinary research, education, and policymaking, emphasizing the importance of integrating diverse epistemological perspectives.

Authors: Cenk PAŞA  , Alper YARDAN
Published: November 2024

This study aimed to determine how administering ascorbic acid (AsA) at different salt concentrations (NaCl) affected the germination and other physiological characteristics of catnip (Nepeta cataria) seeds. For each application, the study employed four distinct AsA applications (0, 50, 100, and 150 mM) and four distinct NaCl concentrations (0, 50, 100, and 150 mM). Germination rate (%), germination time (day), root length (cm), and stem length (cm) were the criteria examined in this study.
This study showed that germination was adversely affected by increased salt concentrations. Treatments with 50 mM and 100 mM AsA also showed positive effects on germination and other measures. It has been shown that catnip plant germination in saline conditions may be positively impacted by the ideal administration of AsA.
Optimal control of the gradient systems
Authors: Tuğba Küçükseyhan
Published: November 2024

In this paper we consider the optimal control problems governed by the gradient systems

for the Ginzburg-Landau free energy

where denotes a potential function and ε is the diffusivity. One example of gradient systems are the Schlögl equation arising in chemical waves with a quartic potential function F(y). Gradient systems are characterized by energy decreasing property . Numerical integrators that preserve the energy decreasing property in the discrete setting are called energy or gradient stable. It is known that the implicit Euler method is first order unconditionally energy stable method. The only second order unconditionally energy stable method is the average vector field (AVF) method. We discretize the gradients systems by discontinuous Galerkin method in space and by AVF integrator in time. We solve optimal control problems for the Schlögl equation with traveling and spiraling waves using sparse and regularized controls .

Published: November 2024

Asthma is a chronic respiratory disorder marked by inflammation and obstruction of the airways, resulting in symptoms such as wheezing, breathlessness, chest tightness, and coughing. Affecting over 300 million people globally, asthma is triggered by genetic and environmental factors, including allergens, pollutants, and respiratory infections. While current treatment strategies, including inhaled corticosteroids and bronchodilators, help manage symptoms, asthma remains a significant public health challenge with no definitive cure. Diagnostic approaches rely on clinical assessment and pulmonary function tests. Looking ahead, future directions in asthma research are focused on personalized medicine, targeting the unique genetic and environmental factors that contribute to asthma variability among patients. Innovative treatments such as biologics, which aim to modulate immune pathways involved in inflammation, are showing promise for severe asthma cases. Additionally, advancements in digital health, such as wearable devices and mobile apps, are improving disease monitoring and patient adherence to treatment plans. Continued efforts are needed to address disparities in asthma care and to explore preventive strategies, such as early-life interventions to reduce the development of asthma in high-risk populations.
This Article discusses the key aspects of asthma, current treatment challenges, and emerging research directions aimed at improving management and reducing the global burden of the disease.

The Nipah virus outbreak in Kerala, India, in 2024 presented significant public health challenges, necessitating an in-depth analysis of its transmission dynamics and the effectiveness of response measures. This study employs the SIR (Susceptible, Infected, Recovered) epidemiological model to simulate the outbreak, focusing on key parameters such as transmission and recovery rates. The model reveals that the outbreak peaked around Day 10, with a maximum of approximately 631 infected individuals, highlighting the rapid spread of the virus. However, timely public health interventions, including contact tracing, isolation, and community engagement, effectively curtailed transmission, resulting in a swift decline in infected cases and a significant recovery rate. By Day 100, nearly the entire population had either recovered or remained uninfected, underscoring the success of containment efforts. This study emphasizes the critical role of proactive health strategies in managing infectious diseases and provides valuable insights for future preparedness against zoonotic outbreaks. The findings highlight the necessity of continuous monitoring and community involvement in strengthening public health infrastructure to mitigate the impact of similar outbreaks in the future.

This paper addresses the growing threat of phishing attacks in the Philippines by developing an engaging educational game designed to enhance information retention and actively engage players in cybersecurity learning. Despite efforts by law enforcement, phishing attacks remain a significant cybersecurity threat in the Philippines, with current preventive measures and awareness campaigns proving insufficient to address evolving cyber threats.
The study aims to evaluate the effectiveness of gamification in cybersecurity education through the development and testing of "Unveiling Shadows," a game developed using Unity Game Engine and C# programming language. Using quantitative survey research methodology, the study collected data from 100 participants aged 12 and above through an online survey utilizing a four-point Likert scale to measure learning outcomes and user engagement.
Results demonstrated that "Unveiling Shadows" achieved high effectiveness in educating players about phishing tactics, with particularly strong outcomes in password security awareness and understanding the risks of sharing sensitive information online. The findings suggest that cybersecurity educators should consider incorporating gamified learning experiences that simulate real-world scenarios to enhance engagement and knowledge retention. Future research should explore the long-term impact of gamified cybersecurity education on user behavior and investigate the effectiveness of this approach across different demographic groups in the Philippine context.

ADEM is diagnosed as an acute disseminated demyelinating disease of the CNS. It is normally initiated by viral infections. The objective of the current research was to elucidate the etiology, immunologic characteristics and management of ADEM in 430 subjects in Hayatabad Medical Complex, Peshawar. Of the viral causes the most commonly identified were influenza, 25%; measles, 20%; and varicella, 18%. Perhaps this may show how distribution of the infective agents common in this region may explain the occurrence of ADEM. They have similarly given out high cytokine concentration particularly IL-6 and TNF-α and similar to past findings they might not only be biomarkers of disease severity but may also be a site of immunomodulation.
As for the reaction to the treatment the favorable responses are 80% of the times on corticosteroids and the IVIG and plasmapheresis are great for severe cases or if the prior one failed. Datalocalized at six months follow-up, the majority of the patients had positively improved in seventy percent with the other ten percent patients’ symptoms nearly dropped down. Therefore, the present research suggests that diagnosis of ADEM should be done early and patients ought to be put on working on formulation of tailor made treatment plans that might improve prognosis of ADEM. Findings regarding genetic profile identifying high risk patients who must be prescribed special medicine are still lacking. Therefore, this study will therefore complement information on Immune defenses and therapeutic approaches in ADEM in a region of the world where viral diseases are common.
