Educação a Distância e Qualidade: Pauta Urgente para as Políticas Públicas na Educação Superior
Authors: Maieski Alessandra , Casagrande Ana Lara , Morosov Alonso Katia
Published: November 2024

Este trabalho consiste em uma análise de documento de fonte primária relativa aos dados da Educação a Distância (EaD) no Brasil, com especial atenção à crescente atuação do setor privado na modalidade. Objetiva-se discutir as formas pelas quais a qualidade da EaD tem sido vinculada a uma narrativa difamatória, na qual “a parte”, que utiliza essa modalidade para lucrar mais com a massividade e formação aligeirada, é considerada como “o todo” do fazer EaD no Brasil. As universidades públicas desempenham um papel social, também via EaD, que não pode ser desprezado, além de algumas instituições privadas que desenvolvem um trabalho comprometido com o processo de ensino-aprendizagem de qualidade. Os dados do Censo da Educação Superior de 2022 e de 2023 indicam que o setor privado responde por 96,2% do total geral de vagas de cursos de graduação, sendo que a EaD representa 75,2% desse total. A evolução do número de cursos de graduação a distância se destaca nos anos de 2017 para 2018, com um crescimento expressivo de 50,71%. Ao longo de 22 anos, a EaD cresceu 91.760% no Brasil. Durante esse período de expansão, de 2013 a 2023, as vagas em cursos de graduação da EaD aumentaram 541%, enquanto as do ensino presencial encolheram. A análise realizada indica que, do ponto de vista das políticas públicas, é fundamental resgatar o princípio da EaD, a necessidade de institucionalização com previsão de estruturação e financiamento, além de direcionar o foco para a formação socialmente referenciada.

In this paper, we study stochastic models for discrete letter encoding and object classification via ensembles of different modality datasets. For these models, the minimal values of the average mutual information between a given ensemble of datasets and the corresponding set of possible decisions are constructed as the appropriate monotonic decreasing functions of a given admissible error probability. We present examples of such functions constructed for a scheme of coding independent letters represented by pairs of observation values with possible errors as well as for a scheme of classifying composite objects given by pairs of face and signature images. The inversions of the obtained functions yield the lower bounds for the error probability for any amount of processed information. So, these functions can be considered as the appropriate bifactor fidelity criteria for source coding and object classification decisions. Moreover, the obtained functions are similar to the rate distortion function known in the information theory.

The paper studies the real-time stereo image-based localization of a vehicle in a prior 3D LiDAR map. A novel localization approach for mobile ground robot, which successfully combines conventional computer vision techniques, neural network based image analysis and numerical optimization, is proposed. It includes matching a noisy depth image and visible point cloud based on the modified Nelder-Mead optimization method. Deep neural network for image semantic segmentation is used to eliminate dynamic obstacles. The visible point cloud is extracted using a 3D mesh map representation. The proposed approach is evaluated on the KITTI dataset and a custom dataset collected from a ClearPath Husky mobile robot. It shows a stable absolute translation error of about 0.11 – 0.13 m. and a rotation error of 0.42 – 0.62 deg. The standard deviation of the obtained absolute metrics for our method is the smallest among other state-of-the-art approaches. Thus, our approach provides more stability in the estimated pose. It is achieved primarily through the use of multiple data frames during the optimization step and dynamic obstacles elimination on depth image. The method’s performance is demonstrated on different hardware platforms, including energy-efficient Nvidia Jetson Xavier AGX. With parallel code implementation, we achieve an input stereo image processing speed of 14 frames per second on Xavier AGX.
An Humourous Day's Mirth
Authors: Chapman George
Published: November 2024

The King of France is melancholy and devolves power to his minion, Lemot, a wordsmith and architect of intrigue. As Lemot probes and taunts members of the court, he reveals their humours or idiosyncrasies of speech and behaviour, uncovers hidden love and secret sins, and exposes fissures in several marriages—including that of the King himself. Hilarity, poignancy and foolishness ensue, ending with a significant lottery, a wedding and renewal of marriage vows. Situating the play within George Chapman's oeuvre and the dramatic genre he initiated, Eleanor Lowe's Introduction explores the "comedy of humours" as a broader cultural phenomenon that reflects contemporary anxieties about the body and identity, gender and social status, containment and control. Generous glosses explain the play's many humoural and topical references, while fuller and further annotations, as well as a facsimile and transcription of the early playbook quarto, are available on the Digital Renaissance Editions website.
O DISTANCIAMENTO DE BRECHT EM TUDO VAI BEM (TOUT VA BIEN, 1972)
Authors: Bronzeri Murilo
Published: November 2024

ResumoO Grupo Dziga Vertov foi um coletivo de cineastas criado, em 1968, por Jean-Luc Godard e Jean-Pierre Gorin, então editor cultural do Le Monde, e que se dissolveu em 1972. O coletivo também surge logo após os eventos do Maio de 68 na França, um marco na política mundial. Os filmes do Grupo Dziga Vertov tiveram muitos temas políticos e que dialogavam com a esquerda francesa da época. A pesquisa tem como objetivo geral analisar o filme Tudo vai bem, buscando aproximações com o “distanciamento” de Bertolt Brecht. A relação entre o filme e Brecht já é conhecida e já foi anteriormente citada por Gorin, mas a pesquisa busca aprofundar o entendimento dessa relação e contribuir com as análises já existentes do filme. Para isso, fez-se um levantamento bibliográfico conceitual sobre os assuntos tratados e uma análise do filme citado seguindo a metodologia de análise fílmica proposta de Manuela Penafria. Em seus resultados, a pesquisa conclui que as aproximações entre Brecht e Tudo vai bem aparecem no travelling que mostra os vários cenários simultaneamente, no humor de algumas cenas, nas quebras da quarta parede e até no trecho inicial com os cheques. E, embora essa relação já fosse conhecida, acredita-se que o artigo atingiu seu objetivo ao aprofundar o entendimento dela e demonstrar como ela ocorre em trechos ainda não comentados como quando o patrão quer ir ao banheiro.AbstractThe Dziga Vertov Group was a collective of filmmakers created in 1968 by Jean-Luc Godard and Jean-Pierre Gorin, who was the cultural editor of Le Monde at the time, and which dissolved in 1972. The collective emerged shortly after the events of May 1968 in France, a landmark in world politics. The films of the Dziga Vertov Group tackled many political themes and engaged in dialogue with the leftist movement in France during that period. The overarching goal of the research is to analyze the film Tout va bien seeking connections with Bertolt Brecht's concept of "distancing effect." The relationship between the film and Brecht is already known and has been previously mentioned by Gorin, but the research aims to deepen the understanding of this relationship and contribute to the existing analyses of the film. To achieve this, a conceptual bibliographic survey was conducted on the relevant topics, followed by an analysis of the mentioned film using the film analysis methodology proposed by Manuela Penafria. In its findings, the research concludes that the connections between Brecht and Tout va bien appear in the tracking shot that simultaneously shows various scenes, the humor in certain scenes, the breaking of the fourth wall, and even in the initial segment involving the checks. Although this relationship was already known, it is believed that the article has achieved its objective by delving deeper into the understanding of it and demonstrating how it manifests in previously unexplored scenes, such as when the boss wants to go to the bathroom.

THE PARADOXES AND CHALLENGES OF ANTHROPOGENIC CLIMATE CHANGE
Authors: Teles Eliana , Halbmayer Ernst , Chacón Noemi
Published: November 2024

A atual crise climática apresenta uma série de desafios sem precedentes em escala global. Apesar da implementação de medidas destinadas a reduzir as emissões e mitigar os impactos da mudança climática, a eficácia dessas medidas é questionável, principalmente no contexto de grupos sociais com bases de recursos restritas e capacidade limitada para lidar com as circunstâncias predominantes. Essa situação serve para ilustrar as injustiças inerentes à abordagem atual da mudança climática e exige o desenvolvimento de estruturas conceituais mais amplas para tratar dessas deficiências.
EMPOWERING MARGINS: FROM CLIMATE CHANGE POLITICS AND TECHNOLOGIES OF AGGREGATE STATES TO PLACE BASED HUMAN CONTRIBUTIONS
Authors: Halbmayer Ernst
Published: November 2024

As conventional mitigation efforts seem insufficient to achieve the goals set by the Paris Agreement, the use of alternative pathways seems inevitable. This paper argues for an empowerment of the conceptual and spatial margins of climate change. This means pluralizing ontologies of climate change, securing and developing existing low-emission practices and recognizing and promoting place-based adaptation strategies. Placing the human and cultural contributions and resilience strategies of the low-emitting half of humanity at the conceptual center of climate action provides an essential and necessary complement to established climate change policies and promises to secure and promote biocultural diversity and low-emitting ways of life.Keywords: Climate change ontology. Mitigation politics, Carbon inequality; Human and cultural contributions; Conceptual and spatial margins

Published: November 2024

En un entorno natural, los sorbetes de plástico de un solo uso o desechables se desintegran en 500 años, mientras que los sorbetes comestibles, elaborados con ingredientes naturales, se disuelven en 40 minutos al entrar en contacto directo con la bebida. El propósito de este estudio fue desarrollar un prototipo de sorbete comestible con ingredientes de interés nutracéutico para el consumo de bebidas. Se diseñó un estudio experimental para determinar la dosis de inulina e isomalt conforme a las normas permitidas para el consumo humano, además, se llevo a cabo un análisis sensorial mediante una prueba de aceptación con escala hedónica de 7 puntos y un grupo focal para evaluar las cualidades del sorbete comestible. Los contenidos de inulina e isomalt en el sorbete fueron del 9.5 % y 30 %, respectivamente. Las calorías fueron de 379.98 kcal/100 g, con una diferencia de 14,83 kcal/100 g respecto a una fórmula con edulcorante 100% calórico. Se evaluó la durabilidad a distintos niveles de pH en bebidas (ácido, neutro y alcalino). Tras 40 minutos de contacto directo con la bebida, no hubo diferencias entre los tres tratamientos. La aceptación del sorbete comestible por los panelistas/consumidores se vio reflejada por el tipo de bebida que se va a consumir (jugo de naranja y té frío comercial).

Authors: Mitts Maryann , Lirgg Cathy D. , Lange Eric
Published: November 2024

During a 6-week period, students in Grades 1-5 participated in 15 sensory activities that focused on processing and integration motor skills. The intervention group participated in 20 minutes of the Minds in Motion maze (10 minutes in the morning and afternoon) while the control group continued with normal school activities. Pre and post difference scores of the dependent variables (Auditory Memory Test, Developmental Reading Assessment, and Office Referrals) were calculated. Manova results showed that the intervention group scored higher than the control on the auditory memory test. Groups did not differ on reading level or classroom behavior. However, post interviews with participating teachers indicated that the maze was a positive addition to the school day, especially with classroom management.

Gry komputerowe są obecnie jednymi z najgwałtowniej i najciekawiej rozwijających się mediów. Książka łączy w sobie perspektywy badawcze teorii gier, filmu i literatury, groznawstwa aby dyskutować o tym, czym gry komputerowe są, w jaki sposób tworzą się relacje między nimi a graczami, a przede wszystkim jak funkcjonują one jak teksty i tworzą znaczenia. Są w niej również zaproponowane narzędzia analityczne dotyczące zarówno ich warstwy tekstowej, jak i procesu recepcji, ukazując w  jaki sposób na styku tych strategii badawczych rodzi się bardziej zrozumiały obraz grywalnych tekstów oraz kultur, które się wokół nich tworzą. Jednym z problemów poruszanych w książce jest kwestia przestrzennych własności gier, które mogą ewokować opowiadania ze względu na angażujące oraz interpretacyjne procesy, którym podlega gracz oraz że możliwym jest postrzeganie środowiska gry nie tylko jako wizualnego spektaklu, ale lokacji, która generuje znaczenie. W książce pojawia się także zagadnienie tworzenia medialnych reprezentacji światów, które generują opowiadania oraz dostarczają różnorodnych sposobów ich doświadczania, będąc głosem w dyskusji wokół problematyki związanej ze świadomą medialnie narratologią.
Configuración espacial de los factores sociodemográficos y materiales que influyen en el capital social de vinculación en territorios forestales
Authors: Custodio González Carlos Alejandro , Pérez Verdín Gustavo , Ortiz Salazar Tania Margarita , Sánchez Ortiz Eduardo
Published: November 2024

El capital social ha sido incorporado como una categoría explicativa en los procesos de cooperación y asociatividad para abordar problemáticas a nivel comunitario. Sin embargo, debido a su naturaleza histórica y cultural, el capital social se manifiesta de manera diferenciada en el espacio. Esta diferenciación está asociada a las condiciones sociodemográficas y socioeconómicas presentes en los territorios. En este contexto, el objetivo del artículo fue identificar las características sociodemográficas de los territorios forestales que influyen en los procesos relacionales de cooperación para el manejo de bienes comunes forestales. Además, se analizó la relación espacial de estos factores con la pérdida de cobertura de estos recursos. Para ello, la base metodológica se sustentó en la combinación de dos métodos cuantitativos: análisis de componentes principales y regresión espacial múltiple, considerando como caso de estudio los territorios forestales del estado de Durango, México. A partir de estos métodos, se identificó la presencia de dos escenarios de proximidad social, con un patrón espacial contradictorio: los territorios con menor grado de proximidad social presentaron una menor pérdida de la cobertura forestal. Esto puede explicarse por el comportamiento de las condicionantes sociodemográficas y materiales del capital social de vinculación a escala local.

A mathematical modeling of the turbulence combustion biodiesel in a compression ignition engine
Authors: MOUZONG Francis BONGNE , AYISSI Merlin Zacharie
Published: November 2024

The present work proposes a new model for biodiesel combustion in an internal combustion engine. This model first includes the balance equations of gas dynamics with heat release. Secondly, a model with special properties that take into account turbulence effects is incorporated. The chemical models implemented in this study are for a biofuel used at less than 100% and for biodiesel-diesel blends. The resulting model is a coupling of equations describing the combustion of biodiesel with premixing. The model obtained is interesting and applicable to a wide range of combustion problems without major modifications. It is then proposed to the scientific community in order to develop internal combustion engines capable of meeting future political expectations regarding the reduction of pollutant emissions from the combustion of internal combustion engines.
Protestant school profile and quality education : Perceptions of protestant secondary school leaders in Rwanda
Authors: Uwajyiwabo Etienne
Published: November 2024

The present study was conducted to investigate the perceptions of protestant school leaders on the relationship between the protestant school profile and quality education in Rwanda. The choice of the topic was based on the recognized contribution of the protestant school profile to quality education improvement and on the research gap on this relationship in Rwanda. The research process was guided by the following main research question: What are the perceptions of protestant school leaders on the protestant school profile and its relation with quality education? To achieve the study objective, a qualitative research approach was adopted using a semi-structured interview to collect data by use of theoretical sampling. For data analysis, qualitative content analysis was used. Through the abduction process, three types of profiles were generated, including vocation-based, Institution-based, and socio-spiritual profiles. The discussion of the results in light of the existing literature highlights a positive contribution of the protestant school profile to quality education, limited to quality output. Additionally, the discussion demonstrates a positive contribution of the protestant school profile to the promotion of unity and reconciliation in Rwanda, to the economic development of Rwanda, as well as to the promotion of religious plurality. Finally, recommendations are addressed to different stakeholders in protestant education in Rwanda including school leaders, school owners, the protestant council of Rwanda, and the Ministry of education.

Authors: Intan Fairuz Zakia  , Izzati Dwi , Atika Atika
Published: November 2024

Background: Postpartum mothers are vulnerable to mental health problems, including baby blues syndrome, which occurs in the first week. Baby blues syndrome has the potential to predict postpartum depression, and if left untreated, it can lead to more severe mental disorders. This study aims to determine the relationship between the level of postpartum maternal anxiety and the occurrence of baby blues syndrome at Universitas Airlangga Hospital. Method: This was a quantitative study with an observational analytic method and a cross-sectional design. The population in this study was mothers 1-2 days postpartum who were treated at Universitas Airlangga Hospital in December 2023. The study involved 33 postpartum mothers sampled using the consecutive sampling method. The instruments used were questionnaires, the Perinatal Anxiety Screening Scale (PASS) to measure anxiety and the Edinburgh Postnatal Depression Scale (EPDS) to measure symptoms of baby blues syndrome. The analysis method used was the chi-square test. Results: Respondents with anxiety without symptoms were 12 (36.36%), none of whom experienced baby blues syndrome. Out of 16 respondents with mild to moderate anxiety and experienced baby blues syndrome, one person (3.03%) did. And out of 5 respondents with severe anxiety and experienced baby blues syndrome, one person (3.03%). The p-value of 0.289 based on the chi-square test. Conclusion: The level of anxiety in postpartum mothers is not related to the incidence of Baby Blues Syndrome.

Authors: Nazman Muhammad , Mohd Hatta Puteri Balqis , Suhaimi Nur Faseeha
Published: November 2024

Introduction: Poor indoor air quality (IAQ) in work environments can reduce productivity and decrease overall performance. This study examines IAQ in university laboratories and its relationship with psychological performance among students in Malaysia. Methods: This cross-sectional study was conducted from October to November 2023 in six laboratories at a Malaysian university, categorised into chemical and non-chemical. A total of 117 students aged 18 to 40 participated. IAQ was measured in real-time for 8 hours during weekdays using instruments for particulate matter (PM2.5, PM10), carbon monoxide (CO), total volatile organic compounds (TVOC), airborne microorganisms, carbon dioxide (CO2), temperature in °C, relative humidity (RH), and air movement. Psychological performance was assessed using the General Health Questionnaire (GHQ-12) and Post Occupancy Evaluation (POE). Data analysis was performed using Kruskal-Wallis, One-Way ANOVA, and Chi-Square tests. Results and Discussion: Significant differences in IAQ parameters were observed for PM2.5 (p=0.007), PM10 (p=0.020), CO2 (p=0.024) and RH (p=0.043). Psychological distress affected 41.9% of students based on the predefined threshold. High CO levels (≥0.67 ppm) and elevated temperatures (≥23.28°C) were significantly associated with increased psychological distress (p=0.011). Students exposed to these conditions were 1.3 times more likely to experience distress (OR=1.3). Conclusion: Specific IAQ parameters, particularly CO and temperature, critically impact students’ psychological well-being. Improving IAQ by reducing CO levels and maintaining optimal temperatures may enhance mental health and performance. Improving IAQ by reducing CO levels and maintaining optimal temperatures may enhance mental health and performance. However, external factors such as personal stressors could not be entirely controlled.

Published: November 2024

Introduction: Microplastic (MP) contamination poses a global environmental threat, affecting terrestrial and marine ecosystems, and human health. This study investigates the presence, density, and composition of MPs in three commercially important shellfish species, oriental angel wing clam (Pholas orientalis), bamboo clam (Ensis leei), and blood cockles (Tegillarca granosa) at Pantai Remis Jeram, Kuala Selangor. Methods: Microplastics in shellfish were quantitatively analyzed for their abundance, colour, size, shape, and composition using microscopic techniques and micro-Fourier Transform Infrared (FTIR). Standard experimental protocols were followed. Statistical analysis of the data was performed using SPSS to identify correlations between these parameters. Results and Discussion: Our findings reveal a significant presence of MP particles in shellfish with T. granosa exhibiting the highest density (2.417 particles/cm³) compared to E. leei (0.721 particles/cm³) and P. orientalis (1.449 particles/cm³). Fibers and fragments were the dominant MP morphotypes, primarily in black color. P. orientalis and T. granosa contained a majority of MPs within the 1 - 5 mm size range, totalling 41 and 56 particles, respectively. Shellfish samples contain polymers of cellulase acetate and polyethylene terephthalate, indicating possible origins from plastic bottles and textile fibres. A statistically significant difference in the mean MP densities in the different species of shellfish was found by one-way ANOVA analysis (p = 0.042, p < 0.05). Conclusion: This study provides relevant data on MP pollution in commercially significant shellfish species. To effectively mitigate this environmental concern and comprehend the long-term ecological ramifications of MP intake by shellfish, more research is required.

Authors: Esumeh Comfort Omogor , Andrew Reigns
Published: November 2024

Introduction: In numerous tropical regions of developing nations, the prevalence of foodborne illnesses is perceived to be more severe than in developed countries, due to insufficient food safety initiatives or the lack of a structured institutional framework for street food vendors. The study's objectives of examining microorganisms associated with fruits and vegetables, the prevailing temperature and the hygiene practices of various fruit and vegetable sellers were all met. Methods: A self-designed questionnaire completed by twenty vendors were used. Laboratory techniques like serial dilution, biochemical testing, and culture techniques were used. A handheld thermometer was used to determine the prevailing temperature, and descriptive statistics using Microsoft Excel was used to analyze data. Results and Discussion: Statistical analysis revealed that 80% of vendors had washing facilities, 70% worked in a clean environment, 20% washed their hands before handling fruits, 70% dressed correctly, and 70% kept their fruits and vegetables above the WHO temperature standard. A laboratory investigation revealed the bacteria counts of (watermelon being the highest 8.3×105, cucumber 5.4×105, carrot 2.3×105, orange 3.7×105). Microbial species encountered were Staphylococcus aureus, Escherichia coli, Salmonella species, amongst others, which increases health risk. Conclusion: The study concluded that temperatures, handling processes, and inadequate hygiene all had impact on fruits and vegetables sold in tropical Bwari area. It also established a link between temperature and the prevalence of bacteria in fruits and vegetables. As a result, the study suggests monitoring and surveillance of fruit and vegetable sellers, national vendor hygiene policies and public awareness.

Authors: Khofiyyah Nida'an , Akhmad Taufiq Mukti  , Laksmi Sulmartiwi
Published: November 2024

Macrognathus aculeatus is a local fish from the Bengawan Solo and Brantas Rivers threatened with extinction. Due to the lack of literacy on the biology of this fish. Biological parameters can be used to determine the condition of this fish in nature. Field observations at five stations from the two rivers were conducted to obtain samples. Biological and reproductive parameters such as weight and length, gonad maturity level (GML), Gonadosomatic Index (GSI), Hepatosomatic Index (HSI), and Condition Factor (CF) were the parameters observed in this study. All data obtained were presented as mean and standard deviation. Furthermore, analysis of variance was conducted using ANOVA (p < 0.05) to determine differences in samples from each observation station. The results showed that some biological factors had significant results (p < 0.05) on Gonadosomatic Index and Hepatosomatic Index). However, there was no significant difference (p > 0.05) in the condition factor. On the other hand, there were significant differences (p < 0.05) in body weight, total length, ovary weight, and fecundity parameters across all sampling sites.

Therefore, studying the structure and content of EVs produced by resident bacteria is crucial to understanding their functionality and impact on the host and other microorganisms.

Methods: Bacterial EVs were isolated by differential centrifugation, their size and concentration were measured by transmission electron microscopy and nanoparticle tracking analysis, and the cargo proteins were identified by liquid chromatography coupled to tandem mass spectrometry. The cytotoxicity of bacterial EVs was tested using the human epithelial cell line A549 and an in vivo model of Galleria mellonella larvae.

Results: The isolation and preliminary characteristics of EVs from two strains of lactic acid bacteria - Lactiplantibacillus plantarum PCM 2675 and Lacticaseibacillus rhamnosus PCM 489 - were presented, confirming the production of vesicular structures with sizes in the range of 50-170 nm for L. plantarum and 80-250 nm for L. rhamnosus . In addition, various proteins were identified within EVs cargo, with distinct locations of origin, including membrane, cytoplasmic and extracellular proteins, and with diverse functions, including enzymes with confirmed proteolytic activity. Furthermore, bacterial EVs did not show statistically significant cytotoxicity to the host under the tested conditions.

Conclusions : A better understanding of the composition and functionality of bacterial EVs may contribute to their future effective use in supporting human health.
Uncovering Cardiolipin’s Function in Neurodegenerative Diseases
Authors: Ferguson David Joshua
Published: November 2024

Cardiolipin (CL), an essential phospholipid, is localized in the mitochondrial inner membrane, where it plays a critical role in oxidative phosphorylation (OXPHOS) and energy metabolism. This study reviews current findings on cardiolipin's function within neurodegenerative diseases (NDDs), focusing on Alzheimer's and Parkinson's diseases, along with Barth Syndrome. Using lipidomics and protein-lipid interaction analysis, we examine the role of CL in mitochondrial integrity and neuronal function. The primary objective is to analyze how alterations in CL composition and distribution can serve as biomarkers and therapeutic targets for NDDs. Results highlight significant insights into the potential for CL-targeted therapies.

Background: The clinical and laboratory features of patients with non-criteria obstetric antiphospholipid syndrome (NC-OAPS), as well as their pregnancy outcomes and ideal treatment are not clearly determined. The aim of this study is to describe the characteristics and outcomes of pregnancies in NC-OAPS and compare them with an obstetric APS (OAPS) cohort. Methods: Retrospective study conducted in a cohort of women referred to a high-risk obstetric unit of a tertiary hospital. Women that were classified as having OAPS or NC-OAPS were included and compared in terms of clinical and laboratory characteristics, management, and subsequent pregnancy outcomes. Results: We identified 107 women with 143 pregnancies, 91 with NC-OAPS and 16 with OAPS. There were no differences in demographic features between both groups. Women with NC-OAPS were more likely to have recurrent implantation failure and were predominantly positive for a single antiphospholipid antibody (aPL) subtype. Both groups were treated similarly (low dose aspirin plus low molecular weight heparin in 87.4% of NC-OAPS and 83.3% of OAPS, p>0.05). Live birth rate (82.4% and 75.0%, respectively, p>0.05) and adverse pregnancy outcomes (31.6% vs 37.5%, p>0.05) in subsequent pregnancies during follow-up were also similar between groups. Conclusions: This study revealed differences in the previous pregnancy morbidity and aPL profiles in women with NC-OAPS and OAPS, although the therapeutic approach and the outcomes of subsequent pregnancies were similar in both groups.
Epidemiological Landscape and Zoonotic Risks of Poultry Diseases in Ethiopia: Implications for Public Health and Poultry Production
Authors: Assefa Behailu
Published: November 2024

Poultry production in Ethiopia plays a vital role in providing high-quality protein and economic opportunities, yet it faces significant challenges due to prevalent infectious diseases that impact both animal health and human well-being. This review synthesizes current knowledge on the epidemiology and zoonotic risks associated with major poultry pathogens in Ethiopia, focusing on bacterial and viral agents. In Ethiopia, poultry production predominantly consists of traditional scavenging systems in rural areas, alongside a growing intensive farming sector utilizing exotic breeds. Despite efforts to improve biosecurity and vaccination practices, the proximity of intensively reared chickens to smallholder and backyard flocks poses challenges. This environment facilitates the transmission of pathogens such as Campylobacter spp. and Salmonella spp., leading causes of foodborne illnesses in humans. Viral diseases like Newcastle disease virus (NDV) and infectious bursal disease virus (IBDV) also pose significant threats to poultry health and production. These viruses not only cause substantial economic losses but can potentially infect humans, highlighting the interconnectedness of animal and human health in poultry farming settings. This review underscores the importance of integrated disease management strategies encompassing enhanced biosecurity, regular surveillance, and vaccination programs tailored to local contexts. Furthermore, the adoption of molecular epidemiology approaches could provide deeper insights into pathogen circulation and evolution, aiding in targeted control measures. Addressing the complex challenges of poultry diseases in Ethiopia requires interdisciplinary collaboration between veterinary, public health, and agricultural sectors. By mitigating disease risks in poultry populations, Ethiopia can enhance food security, improve public health outcomes, and sustainably support its growing poultry industry.

With the rapid advancement of urbanization, the problem of traffic congestion in cities has become increasingly severe. Effectively managing traffic congestion is crucial for sustainable urban development. Previous studies have indicated that fluid dynamics theory can be applied to address flow problems in transportation, and this article aims at utilize CFD to solve congestion issues in urban road traffic. Firstly, a similarity analysis is conducted between fluids and traffic flow at the theoretical level. By converting parameters, the formula of fluid is derived into the formula of traffic flow, thus demonstrating the feasibility of using CFD in traffic flow research. On this basis, targeting recurrent congestion and non-recurrent congestion scenarios, 2D road fluid domains and constraints are constructed based on the common characteristics of each congestion type area. By using Fluent software to analyze the flow conditions under different congestion characteristics, use the smoothness of fluid motion to find out the problems causing traffic congestion and conduct analysis to reveal the microscopic mechanism behind congestion formation. For different types of congestion, in order to clarify the effectiveness of congestion mitigation measures, the geometric design of road intersections and diversion measures are discussed in depth. The traffic pressure is analyzed by adjusting the vehicle inlet angle at intersections or controlling the vehicle flow speed. Finally, the optimal design scheme is obtained by comparative analysis. The work of this article provides new ideas for optimizing urban road design and solving vehicle traffic congestion problems. The optimization measures can effectively reduce the accident rate and improve the efficiency of traffic flow.
Frustrated Synchronization of the Kuramoto Model on Complex Networks

Published: November 2024

We present a synchronization transition study of the locally coupled Kuramoto model on extremely large graphs. We compare regular 405 and 1004 lattice results with those of 120002 lattice substrates with power-law decaying long links (ll). The latter heterogeneous network exhibits ds>4 spectral dimensions. We show strong corrections to scaling and mean-field type of criticality at d=5, while logarithmic corrections at d=4. Contrary, the ll model exhibits a non-mean field smeared transition, with oscillating corrections, suggesting the network heterogeneity is relevant, causing frustrated synchronization, akin to Griffiths effects.

Dietary interventions during chemotherapy hold promise for clinical and supportive care outcomes. We systematically investigated the feasibility, safety, and efficacy of nutritional counseling conducted during chemotherapy. Studies prospectively implemented nutrition counseling during chemotherapy. Articles were identified from three databases—EMBASE, Cochrane Library, and SCOPUS—from inception to October 1, 2024. Feasibility, safety, and efficacy of outcome data were extracted. Among 44 publications, 39 studies recruited 98±80 participants (range 15-360); 38/39 (97%) were randomized controlled trials. One-third (31%) were among patients with breast cancer. Interventions were divided into individualized nutritional counseling (n=21), nutrition counseling plus exercise (n=13), and nutrient-specific dietary patterns (n=10). Many had goals to achieve established nutrition guidelines. Feasibility was high based on attendance at counseling sessions, retention, and/or food log analysis. Overall, there were minimal adverse events related to the interventions. Many studies showed between-group differences favoring the intervention group for body weight (8/24, gain or loss, according to goals), nutritional status (8/9), quality of life (3/10 without and 6/9 with exercise), cancer-related fatigue (7/10), chemotherapy tolerance (6/11), and treatment responses (3/13). In conclusion, nutritional interventions were feasible and safe for patients undergoing chemotherapy and demonstrated preliminary efficacy to improve nutritional status, fatigue, chemotherapy tolerance, and other outcomes.

Currently, therapeutic Fc-fusion protein is used for treating disease. ESAT6 (6-kDa early secretory antigenic target), secreted by Mycobacterium tuberculosis, is involved in immune regulation. Administered via intranasal immunization, ESAT6-Fc fusion protein significantly alleviated allergic airway inflammation and mucus hypersecretion, reduced the proportions of Th2 cells, Th17 cells and eosinophils with no observable histopathological injury to principal organs in ovalbumin (OVA)-induced allergic asthma (AA) model mice. A analysis of the transcriptome was conducted to explore its mechanisms of immune regulation, which confirmed that ESAT6 exerts an anti-AA effect by mainly suppressing some signaling pathways activation including Natural Killer Cell-Mediated Cytotoxicity, T Cell Receptor, Th1 and Th2 Cell Differentiation, Th17 Cell Differentiation, and Chemokine, which all belong to immune system in organismal systems. Meanwhile, The RT-qPCR validation results of Differently Expressed genes (DEGs) including Cd28, Icos, Cd48, Cd247, Cd40l, Itgal, Itgb2 and Ccl5 from the aforementioned pathways were consistent with the RNA-seq results. This study revealed the fundamental mechanisms of immune regulation underlying the effects of ESAT6 on OVA-induced allergic asthma. More importantly, this study provides valuable insights into the application of mucosal immunotherapy in treating AA, and ESAT6-Fc has potential as a secure mucosal immunotherapy agent for AA.
