Abstract

Permafrost is a potentially important source of deglacial carbon release alongside deep-sea carbon outgassing. However, limited proxies have restricted our understanding in circumarctic regions and the last deglaciation. Tibetan Plateau (TP),the Earth's largest low-latitude and alpine permafrost region, remains underexplored. Using speleothem growth phases, we reconstruct TP permafrost thawing history over the last 500,000 years, standardizing chronology to investigateNorthern Hemisphere permafrost thawing patterns. We find that, unlike circumarctic permafrost, TP permafrost generally initiates thawing at the onset of deglaciations, coinciding with Weak Monsoon Intervals and sluggish Atlantic Meridional Overturning Circulation (AMOC) during Terminal Stadials. Modeling elaborates that the associated Asian monsoon weakening induces anomalous TP warming through local cloud–precipitation–soil moisture feedback. This, combined with high-latitude cooling, results in asynchronous boreal permafrost thawing. During the last deglaciation, however, anomalous AMOC variability delayed TP and advanced circumarctic permafrost thawing. Our results indicate that permafrost carbon release, influenced by millennial-scale AMOC variability, may have been a non-trivial contributor to deglacial CO2 rise.

Abstract

Drought stress is a major production constraint of groundnut in Africa and Asia where it is largely grown as rainfed crop. The experiments aim to design an early testing approach for drought tolerance in the groundnut breeding pipeline to ensure sustainable production. A population of 600 multi parent advanced generation inter-cross (MAGIC) lines (MLs) (F8/9 generation) and 100 advance breeding lines (ABLs) were studied in LeasyScan, a high throughput phenotyping platform (HTPP) to assess early canopy growth, and under a managed stress environment (MSE). MSE ensures uniform water application in well-watered and water-stressed plots, while intermittent drought is imposed in water-stressed plots from 10000 cumulative thermal time (CTT) during pod-filling stage. Digital biomass, leaf area 3D and plant height measured under HTPP recorded high heritability along with high genetic gain and were identified for use as selection criteria for early canopy vigour. The second selection criteria is Mean Score Index (MSI) (1 to 10 scale), which accounts for both resilience and productivity capacity indices (RCI and PCI), with the MSI ranging from 1.4 to 8.4. Based on results, a two-step selection approach is proposed for selection of traits required for adaption under drought stress. The approach involves HTPP (LeasyScan) to select early canopy vigour followed by selection based on MSI under MSE. MSE is field based and expensive, hence screening of a large number of selection candidates under HTTP helps to select a relatively small subset of early vigour lines for screening under MSE for agronomic performance.
Factors Influencing Successful Adoption of Health Information Systems in Ethiopia: A UTAUT Framework Analysis
Authors: Kore Tamirat 
Published: November 2024

Abstract

Background: The adoption of health information systems (HIS) is crucial for improving healthcare delivery in Ethiopia. Despite the potential benefits, several factors influence the successful implementation and utilization of these systems. This study utilizes the Unified Theory of Acceptance and Use of Technology (UTAUT) framework to systematically review existing literature on the determinants affecting HIS adoption in Ethiopia.
Methods: A systematic review was conducted following the PRISMA guidelines. Relevant studies were identified through exhaustive searches in databases such as PubMed, Science Direct, IEEE Xplore, and Google Scholar. The inclusion criteria focused on empirical research published between 2019 and 2024 that explored factors influencing the adoption of Health Information Systems (HIS) in Ethiopian healthcare settings. Data were systematically extracted and analyzed to identify the key factors influencing HIS acceptance in Ethiopia, particularly through the lens of the Unified Theory of Acceptance and Use of Technology (UTAUT).
Results: The findings suggest that performance expectancy, effort expectancy, facilitating conditions, and social influence are the primary determinants affecting HIS adoption, respectively. Addressing these key factors is crucial for improving the adoption rates of health information systems, ultimately enhancing healthcare delivery in Ethiopia. Furthermore, this research enhances understanding of how cultural, economic, and infrastructural factors influence technology acceptance in resource-limited settings.
Conclusion: This study underscores the significance of key factors that significantly impact HIS adoption. Performance expectancy, effort expectancy, facilitating conditions, and social influence are the primary determinants affecting HIS adoption, respectively. These critical areas highlight what stakeholders should prioritize to increase the likelihood of successful HIS implementation. Additionally, this research contributes to a deeper understanding of how cultural, economic, and infrastructural elements shape technology acceptance in resource limited settings.
Understanding the Dynamic Behavior of SDOF Systems: A MATLAB-Based Analysis
Authors: Noor Umar Ahmad 
Published: November 2024

Abstract

This report presents a comprehensive analysis of the dynamic response of a Single Degree of Freedom (SDOF) system under varying conditions of damping ratio (ζ), mass (m), and stiffness (k). Using MATLAB, displacement responses were simulated for undamped, underdamped (ζ < 1), critically damped (ζ = 1), and overdamped (ζ > 1) cases. Variations in mass and stiffness were studied to evaluate their impact on system dynamics. The results highlight critical differences in system behavior, demonstrating that damping significantly affects response attenuation, while mass and stiffness influence natural frequency and amplitude. The findings are essential for understanding and optimizing SDOF systems in engineering applications.
Assessing the photodegradation efficiency of benzene, toluene, and xylene (BTX): A comparative investigation using activated charcoal (AC), zeolitic imidazolate framework-8 (ZIF-8), and zirconium metal–organic framework (Zr-MOF)

ABSTRACT

In this study, three different materials were investigated for their ability to degrade benzene, toluene, and xylene (BTX) using light energy. The materials studied were activated charcoal (AC), zeolitic imidazolate framework (ZIF-8), and zirconium metal–organic framework (Zr-MOF). Initially, AC, ZIF-8, and Zr-MOF were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area analysis, and spectroscopic analysis techniques. Based on their excellent features, that is, band gap (5.5, 5.45, and 4.75 eV), surface area (711.5, 1,122.1, and 535.4 m2/g), and pore volume (0.291, 0.369, and 0.628 cm3/g), a comparative photodegradation analysis of BTX was performed in acetonitrile. We found that Zr-MOF is the best photocatalyst to degrade BTX, with degradation percentages of 97, 95, and 94% (B &gt; T &gt; X), respectively, followed by ZIF-8 and AC. Our study suggests that these photocatalysts can be used to degrade BTX using light energy, which could reduce the health and environmental impacts of BTX. Our results illustrate that advanced porous materials may be established as photocatalyst materials with the potential to address the long-standing challenges associated with pollutant degradation.

Published: November 2024

Este artigo objetiva compreender a essência antropológica dos conceitos de mediação implícita e explícita, principalmente, com base nas pesquisas de Oswaldo Francisco Almeida Júnior sob um viés fenomenológico. Trata-se de uma pesquisa teórica e bibliográfica de caráter exploratório-descritivo, com uma abordagem qualitativa e procedimento metodológico baseado na construção do conhecimento científico produzido por Telma Cristiane Sasso de Lima e Regina Célia Tamaso Mioto que consubstanciam três fases de análise da pesquisa: investigação das soluções, análise explicativa e síntese integradora, tendo como referencial teórico o que foi produzido por pesquisadores, como Oswaldo Francisco de Almeida Júnior, Sueli Bortolin, João Arlindo dos Santos Neto, Angela Ales Bello e Giovanni Reale. No processo de pesquisa, percebe-se a manifestação do fenômeno estudado de forma teórica pela pesquisa bibliográfica e pela prática exemplificada por meio de relato de contexto didático-pedagógico de estudo de lendas, como ação cultural que se manifesta em uma essência antropológica, pois tanto a mediação da informação, quanto a informação só possuem sua existência e a manifestação fenomenológica do seu ser em uma vivência informacional na interação de pessoas humanas, nos sujeitos envolvidos no processo da mediação da informação. O fenômeno da mediação da informação é apreendido mediante a vivência fenomenológica como um ato antropológico. O trabalho possibilitou identificar o estudo da mediação da informação a partir da análise e da incorporação de elementos da Antropologia Filosófica e da Fenomenologia, compreendendo que o centro das ações informacionais é a pessoa humana. A pesquisa poderá contribuir para o processo de ensino-aprendizagem nos campos da Ciência da Informação e da Biblioteconomia, bem como no desenvolvimento dos processos de mediação da informação para novas e futuras pesquisas.

Published: November 2024

Inspiradas no modelo schumpteriano de inovação nos segmentos produtivo e tecnológico, as diretrizes das agências multilaterais (Banco Mundial, Organização para a Cooperação e Desenvolvimento Econômico, Banco Interamericano de Desenvolvimento) em favor da agenda inovadora no setor público têm tido, desde o final do século passado, uma ampla capilaridade entre os países. No caso brasileiro, as experiências pontuais tiveram início mais precisamente já na segunda década, possuindo, portanto, um breve histórico de atuação nas instâncias municipais e estaduais e no âmbito federal. O presente artigo busca investigar o nascedouro e as ações, princípios e valores do Pólen - Laboratório de Inovação em Gestão Pública (ENSP-Fiocruz) bem como os principais desafios frente ao estabelecimento de projetos em favor da inovação organizacional. Visando o alcance do referido objetivo, serão recuperadas conceitualmente as categorias inovação e laboratórios de inovação. Para a realização do estudo, será efetuada uma pesquisa bibliográfica e documental, aliada à técnica da observação participante, caracterizada pelo fato de os participantes do projeto serem também investigadores do fenômeno. Tem-se como hipótese que os programas de inovação no campo da gestão têm conquistado as várias instâncias do setor público, todavia tal agenda pode encontrar resistências de setores em função de fatores políticos, ideológicos e organizacionais. Como as categorias “protagonismo das pessoas e usuários”, “transparência” estão presentes nos programas inovadores, torna-se igualmente fundamental destacar o papel da cultura organizacional para as ações de inovação.

Published: November 2024

Background
Extremely preterm infants (EPIs) often require advanced respiratory support to survive, and one such intervention is the heated, humidified, high-flow nasal cannula (HHHFNC). While the use of this cannula in EPIs has been studied, the relationship between its use and the length of hospital stay is an important yet unexplored research area that we aim to investigate in this study.

Methods
In a quantitative retrospective cohort study, data were extracted from an electronic database. The study included all EPIs younger than 28 weeks of gestational age admitted to the neonatal intensive care unit of a tertiary hospital from January 1, 2020, to December 31, 2022. The descriptive analysis was conducted to describe each infant’s demographic, maternal, and neonatal characteristics. A chi-squared test was also conducted, and a p-value of < 0.05 was considered statistically significant.

Results
The findings suggest that infants who receive an HHHFNC have a longer hospital stay than those who do not. Specifically, infants who did not receive a cannula spent 42.5 days on average in the hospital, compared with 99 days among those who received it, with a significant p-value (p=0.0001).

Conclusion
Infants receiving a cannula stay in hospital on average for twice as long as those who do not. However, to reduce the possibility of bias and produce more reliable results, we advise conducting clinical trials or prospective studies in future research.

Authors: Sahbudin Muhammad , Hermawan Wawan , Sutejo Agus 
Published: November 2024

Used engine oil is a waste from various types of machinery that has potential as an alternative fuel. The viscous characteristics of used engine oil require viscosity adjustment to be utilized as fuel. Nowadays used engine oil burners are generally using an external heater as an initial preheater, which causes the thermal efficiency decreased. The aims of this study are optimizing the design of the used engine oil burner by adding an initial heater and to find the optimum operating conditions of the burner to improve thermal. The initial heater is a spiral-shaped heat exchanger around the flame inside the burner, using its heat to decrease the viscous of used engine oil, so the used engine oil can be used as burner fuel. This study is varying the combustion air flowrate at 3.2×10-3 kg/s, 4.6×10-3 kg/s, and 6.4×10-3 kg/s and fuel rates of 2.1×10-4 kg/s, 3.1×10-4 kg/s, and 4.3×10-4 kg/s so the best performance of the burner will be observed. The results were obtained the best burner performance air flowrate of 4.6×10-3 kg/s and fuel flow rate of 4.3×10-4 kg/s, producing flue gas heat of 544°C, useful energy of 2.69 kW, and a resulting thermal efficiency of 59.54%.

Résumé

Les chutes chez les aînés (65 ans et plus) constituent un problème de santé publique au Canada. Les blessures liées aux chutes sont susceptibles d’entraîner une réduction de la qualité de vie chez les aînés ou de causer la mort. Elles entraînent également des coûts importants en matière de soins de santé. Il est essentiel de réaliser un suivi des blessures et des décès liés aux chutes chez les aînés afin de mieux en comprendre les tendances temporelles et les caractéristiques et d’évaluer les stratégies de prévention des chutes. Nous avons utilisé les plus récentes données de la Base canadienne de données de l’état civil – Décès, de la Base de données sur les congés des patients et du Système national d’information sur les soins ambulatoires pour analyser les tendances des décès, des hospitalisations et des visites à l’urgence liées aux chutes chez les aînés au Canada sur plus de dix ans. Nous avons également effectué une analyse en fonction de l’âge et du sexe. En 2022, dans l’ensemble du Canada (à l’exception du Yukon), 7 189 aînés sont décédés en raison d’une chute. Entre 2010 et 2022, de manière générale, le nombre et le taux de décès attribuables aux chutes ont augmenté. Au cours de l’exercice 2023-2024, il y a eu 81 599 hospitalisations liées aux chutes dans l’ensemble du Canada (à l’exception du Québec) et 212 570 visites à l’urgence liées aux chutes en Ontario et en Alberta. Entre 2010-2011 et 2023-2024, si la tendance générale des taux d’hospitalisation et de visite à l’urgence liées aux chutes n’a pas augmenté, leur nombre a généralement augmenté d’une année sur l’autre, sauf en 2020-2021, soit au début de la pandémie de COVID-19. En ce qui a trait à l’âge et au sexe, les taux de décès, d’hospitalisation et de visite à l’urgence ont augmenté avec l’âge à la fois chez les hommes et chez les femmes. Compte tenu du vieillissement de la population, la surveillance continue des tendances est essentielle pour la prévention des chutes.

Published: November 2024

La reciente situación de pandemia mundial impulsó la generación de reportes abiertos de movilidad, iniciativa creada por la empresa Google en apoyo a las políticas sanitarias asociadas al COVID-19. El cambio significativo en el flujo de vehículos durante la situación de pandemia y la variación en el consumo de combustible asociado al transporte y a diversas actividades productivas, requirió la creación de nuevos modelos predictivos relacionados con un conjunto de datos inusuales (por ejemplo, la geolocalización de los conductores). La manipulación y el análisis adecuado de estos datos proporcionan un pronóstico que mejora la previsión de la demanda de combustible asociada al consumo real. En este trabajo analizamos las bases de datos de la venta de combustibles (Nafta y gasoil), disponibles y abiertas en sitios web oficiales e información de la empresa YPF. Los resultados muestran una correlación positiva entre las variables relacionadas a la demanda de estos combustibles y los registros de movilidad de Google, con ciertas particularidades. El lenguaje de programación utilizado para el desarrollo del código de visualización, geoestadística, cálculo predictivo y reportes de la investigación es “R”.
Objective assessment of computed tomographic pulmonary attenuation of inspiratory and expiratory series in dogs with and without bronchomalacia
Authors: Gerhard Charlotte , Masseau Isabelle , Vientos-Plotts Aida , Petroski Gregory F. , Reinero Carol 
Published: November 2024

Abstract

OBJECTIVE
To document objective metrics of attenuation of the pulmonary parenchyma on inspiratory and expiratory breath-hold CT in dogs with bronchomalacia (BM) and dogs without BM (NoBM) using automated software analysis. Metrics included mean lung attenuation, percent low-attenuation area at −856 HU, percent high-attenuation area at −700 HU, and percent attenuation area between −600 and −250 HU.

ANIMALS
Client-owned dogs with BM (n = 123) and NoBM (20).

METHODS
This retrospective study utilized 3D Slicer software (Brigham and Women's Hospital) to assess pulmonary CT attenuation. Analysis used Spearman correlation and 2-way ANOVA with beta regression.

RESULTS
Comparing the difference between inspiratory and expiratory phases, there was a significantly greater increase in mean lung attenuation (P = .001), a significant reduction in percent low-attenuation area at −856 HU (P = .016), and a significant increase in percent high-attenuation area at −700 HU and percent attenuation area between −600 and −250 HU (P < .001 and P < .0001, respectively) in BM versus NoBM dogs.

CONCLUSIONS
The higher inspiratory and expiratory difference in lung attenuation in BM compared to NoBM dogs supports the presence of impaired parenchymal aeration downstream of segmental and subsegmental airway collapse.

CLINICAL RELEVANCE
Quantitative image analysis holds promise for objectively evaluating changes with BM.
Effects of luteinizing hormone receptor activation in immortalized neoplastic canine T lymphocytes
Authors: Maxwell Elizabeth , Dietz Alexa , Li Wanli , Kutzler Michelle 
Published: November 2024

Abstract

OBJECTIVE
The expression of luteinizing hormone (LH) receptors has been reported in canine nonneoplastic and neoplastic lymphocytes. This study aimed to determine the effect of LH receptor activation in neoplastic canine T lymphocytes.

METHODS
Cell lines (CLC, CLK, EMA) derived from 3 dogs with primary T-cell lymphoma were used. Cell lines were previously phenotyped and evaluated for LH receptor expression with flow cytometry. Cell lines were stimulated with increasing concentrations (0, 4, 400, and 4,000 U/mL) of human chorionic gonadotropin (hCG; an LH receptor agonist), RNA was extracted, cDNA was synthesized, and gene expression was determined using quantitative PCR and the 2-ΔΔCt method. Cell lines were stimulated with the same increasing concentrations of hCG, and cell proliferation, adhesion, and transmigration were determined using commercial assays. The effects of LH receptor activation were compared between hCG concentrations using a one-way ANOVA. Significance was defined as P < .05.

RESULTS
LH receptor stimulation increased LH receptor gene expression in the CLC cell line, and there was a trend for increased expression in the EMA cell line but no effect in the CLK cell line. Activation of LH receptors increased proliferation in all 3 cell lines, endothelium adhesion in 2 cell lines (CLC, CLK), and transmigration in 2 cell lines (CLK, EMA).

CONCLUSIONS
LH receptor stimulation using hCG increased LH receptor gene expression in neoplastic canine T lymphocytes and increased cell proliferation, adhesion, and transmigration.

CLINICAL RELEVANCE
These findings may provide a physiologic mechanism for the increased incidence of lymphoma reported in dogs with sustained supraphysiologic LH concentrations.
