تعتبر طريقة إزالة النترات من الماء باستخدام المعادن صفرية التكافؤ من الطرائق التي تثبت فعاليتها العالية يوماً بعد يوم، وخاصةً الحديد صفري التكافؤ. إلا أن أبرز العوائق التي تشكل عقبةً أمام الاستمرار باستخدامه هي تعرض سطحه للتخميل أثناء التفاعل، وتشكل أيونات الأمونيوم كمنتج رئيسي لاختزال النترات تحت ظروف المعالجة.
تم في هذا البحث دراسة تأثير الغضار أثناء إزالة النترات بواسطة الحديد الصفري، تم استخدام الغضار الخام والغضار المنشط بالطريقة الحمضية والغضار المعدل بجسيمات الحديد النانوية بنسبة (1:1).
أظهرت النتائج أنه يمكن إزالة 80% من أيونات النترات الموجودة في الماء باستخدام Fe0 بتركيز 40g/L مع 4 ≥ pH لمدة 120 دقيقة عند درجة حرارة الغرفة، كما أن إضافة الغضار الخام يقلل من الكفاءة بسبب خواصه القلوية مما أدى إلى لتفاعل تثبيط تفاعل Fe0 مع النترات. بينما أدى الغضار المنشط بالحمض إلى زيادة إزالة النترات بزيادة الجرعة المضافة. كما أعطى الغضار المعدل فعالية أكبر من الغضار الخام والغضار المنشط بالحمض، وزادت نسبة الإزالة إلى% 95.33 تحت ظروف المعالجة المطبقة. بينما تم تخفيض الأمونيوم مع زيادة الغضار المضاف بجميع أشكاله (الخام والمنشط والمعدل). وأخيراً لوحظ أن إضافة 5 غرام/لتر من الغضار (الخام، المنشط، المعدل) كانت كافية لتخفيض نسبة النترات والأمونيوم للحدود المسموح بها حسب المواصفة السورية رقم 45/2007 لمياه الشرب.

A abordagem e sistematização de sequências didáticas que tratem sobre a Educação Sexual tem sido cada vez mais urgentes em períodos pós-pandemia. Com o aumento no número de gravidezes na adolescência e na quantidade de abusos sexuais noticiados contra adolescentes, são notados indícios de que muito é necessário ser esquematizado no cotidiano escolar para vivência plena do adolescente em sociedade, a fim de que seu repertório variado viabilize uma vida mais digna enquanto cidadão e oportunize situações que lhe deem margem a ser agente transformador das desigualdades sociais existentes. O uso de metodologias ativas é cada vez mais importante, pois além de melhorarem a aprendizagem discente, colocam o aluno no centro do processo educativo, como ator principal das ações educacionais. Através de rodas de conversa, para retirada de dúvidas, exposição teórica de conteúdos, por meio de esquematizações do corpo humano e construção de um modelo de baixo custo da anatomia e fisiologia do sistema reprodutor masculino, pôde-se melhor contextualizar a temática sexualidade em uma escola de Ensino Fundamental e, inclusive, conversar mais abertamente, com base em evidências científicas, sobre a reprodução e sexualidade humanas. Assim, foi possível a construção de aprendizados sobre a sexualidade humana e uma melhoria na comunicação interpessoal, fazendo com que os discentes ficassem mais seguros em conversar sobre a temática.
Rupture Mode Preferences of Crustal Earthquakes in Japan
Authors: Shibata Ritsuya , Aso Naofumi
Published: November 2024

Rupture propagation is controlled by the energy balance between the energy release rate and the fracture energy, which varies according to the rupture mode. Although previous studies have primarily investigated rupture modes for entire ruptures, this study focuses on the rupture mode during rupture propagation at each spatiotemporal point. Specifically, we introduced an approach to evaluate the rupture propagation direction and compared it with the slip direction. Consequently, various distributions of the spatiotemporal rupture modes were obtained. Via stochastic analysis using this approach, we confirmed that rupture propagation exhibited slight directional preference regarding the rupture mode, which is expected from the framework of fracture mechanics. In contrast, we found that fault roughness, such as bending near the hypocenter, can function as a barrier. Additionally, there is a case where a large stress drop by a previous earthquake inhibited the rupture propagation. This new approach to evaluate the rupture propagation direction can quantitatively represent these effects of rupture attenuation during source processes.
A Photonic Crystal Receiver for Rydberg Atom-Based Sensing

Published: November 2024

Rydberg atom-based sensors use atoms dressed by lasers to detect and measure radio frequency electromagnetic fields. The absorptive properties of the atomic gas, configured as a Rydberg atom-based sensor, change in the presence of a radio frequency electromagnetic field. While these sensors are reasonably sensitive, the best conventional radio frequency sensors still outperform Rydberg atom-based sensors with respect to sensitivity. One approach to increase the sensitivity of Rydberg atom-based sensors is to engineer the vapor cell that contains the atomic gas. In this work, we introduce a passive, all-dielectric amplifier integrated into a Rydberg atom-based sensor vapor cell. The vapor cell is a combination of a slot waveguide and a photonic crystal. The structural features of the vapor cell yield a power amplification of ~ 24 dB. The radio frequency electromagnetic field is coupled adiabatically into the slot waveguide and slowed to increase the interaction between the radio frequency field and the atoms to effectively amplify the incoming signal, i.e., increase the Rabi frequency on the radio frequency transition. The work shows the utility of vapor cell engineering for atom-based quantum technologies and paves the way for other such devices.

Age- and sex-related differences in immune cell compositions and immune outcomes have been identified in adult and aging populations, but a comprehensive and nuanced characterization of these changes during the rapid developmental window of early life is lacking. We explored the association with sex and age within the immune system in CHILD, a Canadian longitudinal pediatric cohort, leveraging DNA methylation (DNAm) from whole blood samples collected at ages one and five years (n=760 paired, 356 female and 404 male). Using DNAm-based computational cell type deconvolution, we observed changes in all twelve estimated immune cell type proportions between these ages in a pediatric population and found significant differences in the context of biological sex. We also identified distinct age- and sex-specific DNAm signatures in the immune system in the first five years of life. Notably, there were few age-specific DNAm changes and the sex-specific DNAm were consistent across this early life developmental window. We were then able to validate many of the sex-specific DNAm changes in separate pediatric cohorts. This insight not only enhances our understanding of pediatric immune maturation and system composition in a healthy population but highlights the existence of sex-based differences prior to puberty.

Published: November 2024

Synapse dysfunction is tightly linked to cognitive changes during aging, but underlying mechanisms driving dysfunction are minimally understood. The extracellular matrix (ECM) can potently regulate synapse integrity and plasticity. Yet the status of the brain ECM during aging remains virtually unexplored. Using novel ECM-optimized proteomic workflows, we discovered striking regional differences in ECM composition and aging-induced ECM remodeling. ECM status was also aligned with preserved synapse protein abundance across key basal ganglia nuclei. Moreover, using foraging-based behavioral paradigms and confocal imaging in fixed tissue, we demonstrated that reduced ECM-synapse remodeling and microglial aging phenotypes are both linked with deficits in goal-directed behavior in aging mice. Finally, using mouse models of microglia ablation and premature microglial aging, we identified microglial aging phenotypes that promote ECM deposition and synapse numbers. Together, these foundational observations implicate glial-ECM interactions in the regulation of synapse function and cognitive abilities across the lifespan.

Background: Malignant pleural effusion (MPE) signals a disease with poor prognosis, high morbid-mortality. Studies of MPE in murine models have reproduced its formation and metastases, and have propose therapies for its control. Drugs associated with nanoparticles (nab) can reduce toxicity and increase action on the tumor cell. Our objective was to evaluate nab-Paclitaxel associated or not with intrapleural anti-VEGF in model of MPE.
Methods: Intrapleural LLC-cells were injected in 250 mice. After 7 days, mice received weekly intrapleurally Paclitaxel, nab-Paclitaxel, anti-VEGF, nab-Paclitaxel+anti-VEGF or Saline (untreated). Twenty animals from each group weekly were weighed, evaluated for mobility and followed until death. Ten animals from each group were euthanized on 7th, 14th or 21st day for evaluation of pleural fluid volume, cytology, LDH, IL-6, VEGF, TNF-α and histological analysis.
Results: Pleural carcinomatosis was lethal in all groups, with longer survival in nab-Paclitaxel+anti-VEGF group. Pleural fluid was greater in untreated and Paclitaxel groups, with the lowest levels in nab-Paclitaxel+anti-VEGF group. Tumor implantation in pleura was observed in all groups with the lowest scores in animals that received nab-Paclitaxel+anti-VEGF.
Conclusions: In this experimental model of MPE, intrapleural nab-Paclitaxel associated with anti-VEGF significantly increased survival time, reduced pleural fluid volume and pleural implants.
Connected Components on Lie Groups and Applications to Multi-Orientation Image Analysis

Published: November 2024

We develop and analyze a new algorithm to find the connected components of a compact set I from a Lie group G endowed with a left-invariant Riemannian distance. For a given delta>0, the algorithm finds the largest cover of I such that all sets in the cover are separated by at least distance delta. We call the sets in the cover the delta-connected components of I. The grouping relies on an iterative procedure involving morphological dilations with Hamilton-Jacobi-Bellman-kernels on G and notions of delta-thickened sets. We prove that the algorithm converges in finitely many iteration steps, and we propose a strategy to find an optimal value for delta based on persistence homology arguments. We also introduce the concept of affinity matrices. This allows grouping delta-connected components based on their local proximity and alignment.
Among the many different applications of the algorithm, in this article, we focus on illustrating that the method can efficiently identify (possibly overlapping) branches in complex vascular trees on retinal images. This is done by applying an orientation score transform to the images that allows us to view them as functions from L2(G) where G=SE(2), the Lie group of positions and orientations. By applying our algorithm in this Lie group, we illustrate that we obtain delta-connected components that differentiate between crossing structures and that group well-aligned, nearby structures. This contrasts standard connected component algorithms in R2.

Background Lymphogranuloma venereum is a sexually transmitted infection caused by Chlamydia trachomatis ompA-genotypes L1-L3, with increasing numbers of detected cases across Europe. Here, we analysed diversity and temporal distribution of the LGV ompA-subvariants detected in Portugal between 2007 and 2023, in order to better understand the dissemination and diversification landscape of LGV strains.Methods The collection of the Portuguese National Reference Laboratory includes 1188 LGV ompA-genotyped samples between 2007 and 2023. In-depth analysis of the diversity of LGV ompA-subvariants circulating in Portugal across the years was performed, identifying newly described subvariants and integrating this data in a comprehensive compilation with all representative LGV ompA-subvariants described globally.Results L2 ompA-variant (L2/434/Bu) was consistently the most frequently detected in our collection, with annual proportions ranging from 34.0–82.9%, between 2016 and 2023. L2bV5 was the second most frequent followed by L2b, ranging from 5.0–27.9% and 2.6–23.7% across the years, respectively, from 2017 to 2023. We highlighted the emergence and considerable increase in circulation of L1-like ompA-subvariants in recent years, representing 13.7% of LGV sequences in 2023. We also identified thirteen novel LGV ompA-subvariants that had not been described before, differing by up to three mutations from the respective genotype reference sequences.Conclusions This study contributes for the worldwide picture of the LGV molecular epidemiology, highlighting the importance of long-term molecular surveillance to monitor the circulation and geographical spread of LGV, and timely identify and track new strains, such as the recently emerging L1-like ompA-subvariants.

Authors: Sharma Shashwat
Published: November 2024

This paper explores the integration of emotionally intelligent marketing tactics to drive brand innovation and repositioning during crises. The role of emotional intelligence (EI) in leadership is pivotal, especially in managing crises, enhancing communication, and inspiring organizational resilience. Using case studies, the research highlights how emotionally intelligent leaders, such as Howard Schultz and Jacinda Ardern, responded to crises with empathy and decisive action, fostering trust and innovation. The study also examines how EI impacts decision-making, conflict management, and employee morale while promoting flexibility, creativity, and transparency. Furthermore, the analysis underscores the influence of emotional intelligence in transforming leadership styles, boosting team cohesion, and creating long-term resilience. Despite the benefits, the research acknowledges the potential limitations of over-reliance on EI, emphasizing that effective leadership also requires a balance of technical skills and swift decision-making in crisis scenarios. This paper offers valuable insights into the intersection of crisis leadership and emotional intelligence, ultimately providing strategies for fostering an emotionally intelligent organizational culture.
THE IMPACT OF ARTIFICIAL INTELLIGENCE ON TEACHING CAREERS: PEDAGOGICAL, ADMINISTRATIVE AND ETHICAL CHALLENGES AND OPPORTUNITIES
Authors:   Federal Institute of Parana, Department of Management and Business., Goncalves Dos Santos Marcio
Published: November 2024

This article reviews the impacts of Artificial Intelligence (AI) on teaching careers, with a focus on the pedagogical, administrative, and ethical dimensions, based on an analysis of recent studies (2022-2024). In the pedagogical dimension, AI has the potential to personalize teaching through adaptive systems and virtual tutors, adjusting content to students needs. However, this personalization could compromise teachers autonomy, as they may become dependent on algorithms for decisions regarding lesson pacing and content. In the administrative dimension, AI automates tasks such as grading and lesson planning, allowing for more teaching-focused time. However, this requires new training and technological adaptations, which may increase teachers workloads. In the ethical dimension, challenges such as data privacy, algorithmic bias, and digital exclusion could exacerbate educational inequalities. The article provides recommendations for leveraging AI as a teaching aid while preserving teacher autonomy and ensuring ethical and inclusive implementation. Methodological limitations, such as the narrow temporal scope and the lack of long-term impact studies, are acknowledged. The article also calls for future research on AI integration in various educational contexts and the development of public policies to ensure equitable technology adoption in schools and universities.

Published: November 2024

Objective: This study aims to evaluate the differences in heart rate variability (HRV), a biomarker of autonomic nervous system, between offspring of normotensive and hypertensive parents to understand the genetic predisposition of autonomic dysfunction. Methods: This study was a cross-sectional observational study.Two groups of healthy adults, offspring of parents with hypertension (n = 50) and offspring of parents with normal blood pressure (n = 50). Short-term HRV was measured using 5-minute electrocardiogram (ECG). HRV indices such as time and frequency domainwere measured. Data were compared by using independent t-tests, with p < 0.05 being considered as statistically significant. Results:The offspring of parents with hypertension showed significantly lower HRV, with SDNN (30.5 Â± 8.2 ms) compared to offspring of parents with normal blood pressure (45.2 Â± 7.1 ms, p < 0.001). RMSSD also was significantly lower in offspring of hypertensive group. Low-frequency (LF) power was higher in offspring of parents with hypertension,while high-frequency (HF) power was significantly reduced in them compared to the normotensive group. The LF:HF ratio was higher in offspring of parents with hypertension (2.80 Â± 0.85) compared to the normotensive group (1.40 Â± 0.60, p < 0.001), indicating sympathovagal imbalance. Conclusion: Offspring of parents with hypertension hadlower HRV, suggesting autonomic dysfunction even in the absence of clinical hypertension. These findings emphasize the potential role of genetic predisposition in the early onset of autonomic dysregulation Further studies are required to understand mechanisms contributing to these differences in HRV.

The innovation is the use of a low cost digital microscope with a USB (universal serial bus) interface to monitor the experimental activities of steel corrosion and water electrolysis in the context of teaching electrochemistry in a physical chemistry graduation course. Thirty-three students from the chemical engineering course at a university in Northern Brazil participated in this research, who were studying the discipline, arranged in groups. The results show that the students performed well in the scientific skills assessed during the steel corrosion experiment due to the apparatus. However, in the water electrolysis experiment, there were more difficulties, especially in communicating scientific ideas. Participants reported that using the microscope helped them understand chemical phenomena and increased curiosity and learning. It highlights the importance of the pedagogical approach based on experimental activities, which are similar to the practices of science, allowing students to be active agents in the construction of knowledge and the use of the low cost digital microscope as an innovative tool in teaching electrochemistry.

Authors: Allsop Yasemin , Kalelioglu Filiz
Published: November 2024

This study investigated the effectiveness of the ‘Match it’ card sorting activity for evaluating the prospective teachers’ knowledge and understanding of computational thinking (CT) concepts. 146 primary prospective teachers were asked to sort 26 scenarios and words alongside nine images under five main computational concepts: algorithmic thinking, abstraction, decomposition, patterns & generalisation, and evaluation. The study found that the card sorting activity, as a method for assessment was useful, however, the issues around the design and the content of the current card sorting activity were reported by students which suggests that further revisions should be made to improve the effectiveness of the tool.
Curriculum Framework and Assessment Approach for Computational Thinking in the Early Years
Authors: Critten Valerie , Hagon Hannah , Aslan Unlu Melike
Published: November 2024

In light of current developments, there is an increasing effort to integrate computing-oriented activities into the education of children as young as two years old. Although the computing strand is not officially addressed in the Early Years Foundation Stage Statutory Framework (DfES, 2024), a small number of early years teachers in England implement computing-oriented activities to ensure that young children progress from early years to Key Stage 1. A particular gap in the field is that previous research on computational thinking concepts never or rarely establish curriculum links in a way that teachers can utilise in their practices. This theoretical article therefore proposes a curriculum-based framework for both teaching and assessing computational thinking (CT) in early years education as assessment is not possible without pedagogic guidelines. Offering a sample lesson plan with links to the Early Learning Goals, this framework aims to encourage teachers, including those without specific computing training, to integrate CT concepts more explicitly into their teaching and enables them to monitor and assess their pupils' progress in relevant skills.
Investigating the impact of introducing pair programming to primary computing education on female pupils’ attitudes towards computing
Authors: Childs Katharine , Sentance Sue
Published: November 2024

Gender balance in computing education is a decades-old issue that has been the focus of much previous research. In K-12, the introduction of mandatory computing education goes some way to giving all learners the opportunity to engage with computing throughout school, but a gender imbalance still persists when computer science becomes an elective subject. The study described in this paper investigates whether introducing pair programming would make a difference to primary-aged girls’ attitudes to computing and intent to study the subject in the future. A randomised controlled trial (RCT) was designed and implemented around a 12-week intervention with 785 female pupils between the ages of 8 and 10 years, alongside a qualitative evaluation investigating teachers’ and pupils' experience of the interventions and the development of materials and teacher preparation resources.  The results of the RCT showed no statistically significant changes in student attitudes towards computing or intent to study further, although the qualitative data indicated that both teachers and pupils found the interventions engaging and enjoyable. Themes emerging from the qualitative data point to the importance of collaboration in supporting a development in pupil confidence. Overall, these results emphasise the societal and systemic barriers around computer science and technology engagement across genders that persist despite many initiatives being implemented over many years.

Published: November 2024

Countries are under significant pressure from climate change due to high levels of carbon emissions, and they are working towards carbon neutrality (CN). This is particularly relevant for Saudi Arabia and the United Arab Emirates, which heavily rely on fossil fuels. Therefore, this study aims to suggest solutions for these countries. Specifically, it examines how sustainable management practices (SMP) impact CN. Additionally, it explores the moderating role of strong policies in the relationship between SMP and CN. To strengthen the study's findings, data were collected from 795 respondents across 244 firms in industries like oil, gas, iron, and copper extraction, selected based on their carbon emissions and potential for adopting sustainable practices. Using ordinary least squares regression, the study found that SMP has a significant positive effect on CN. Moreover, strong policies significantly enhance the relationship between sustainable practices and CN in both countries. Policymakers are encouraged to reinforce environmental regulations and offer incentives for adopting green technologies and practices. Effective policies can ensure the consistent use of SMP, leading to a significant reduction in carbon emissions.

Published: November 2024

A interdisciplinaridade é um termo comum no cenário das pesquisas, documentos e diretrizes para a educação brasileira. Pesquisas recentes alertam que, dentre outros aspectos, não cabe mais uma formação docente de forma linear e fragmentada. A partir da aplicação de 31 questionários, esta pesquisa objetivou analisar de que maneira a interdisciplinaridade está presente na formação inicial dos professores das áreas das Ciências Naturais. Participaram deste estudo sujeitos que concluíram ou nos anos finais da graduação em licenciaturas áreas das Ciências Naturais e do curso de licenciatura em Ciências Naturais. Os resultados apontaram conhecimentos adequados sobre a interdisciplinaridade de parte dos sujeitos participantes. No entanto, as instituições não são responsáveis de forma sistêmica pela construção desses conhecimentos. Os participantes desta pesquisa também apontaram os desafios para a promoção de práticas interdisciplinares, bem como as possíveis articulações interdisciplinares de suas disciplinas.

Authors: Boege Selina , Milne-Ives Madison , Ananthakrishnan Ananya , Cong Cen , Sharma Aditya , Anderson David , Meinert Edward
Published: November 2024

Background

The researchers have used mobile phones to assist in monitoring, analyzing, and managing moods to acquire insight into mood patterns. There is a lack of evidence in their use as clinical tools and interventions, which necessitates a comprehensive review and quality assessment to understand barriers and facilitators for app implementation as an impactful clinical intervention.

Objective

This review aims to (1) provide an overview of the recent evidence on mobile mood-monitoring apps that are intended for facilitating self-management and support of mental health in children, adolescents, and young people; and (2) investigate the quality of publicly available apps.

Methods

The study will first involve a scoping review of the literature on mood-monitoring apps for children, adolescents, and young people followed by an evaluation of features of the apps available in the marketplace. The scoping review will follow the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines and search 6 databases— Embase, CINAHL, PubMed, ACM Digital Library, Scopus, and Springer LNCS—for relevant studies and reviews published in the last 3 years. The author will then screen the references, extract data from the included studies, and analyze them to synthesize the evidence on mood apps. Next, the Apple App Store and Google Play Store will be searched for mood apps. A total of 2 independent reviewers will screen the apps based on eligibility criteria, and disagreements will be resolved through consensus. The features of the selected apps will then be evaluated using the Mobile Health Index and Navigation framework, and descriptive analysis will be used to synthesize the findings.

Results

Literature search and screening began soon after submission of the protocol and is expected to be completed by September 2024. The app evaluation will be completed by October 2024.

Conclusions

Combined, the scoping literature review and app evaluation will provide an in-depth overview of the most recent scientific evidence related to mood apps and the quality of apps actually available for use.
