Authors: Kim Wonsun , Park JaeWoo , Jeong HyeRyun , Lee Kimin , Yang Sui , Choi Eun Ha , Park Byoungchoo
Published: January 2025

Hybrid organohalide perovskites have received considerable attention due to their exceptional photovoltaic (PV) conversion efficiencies in optoelectronic devices. In this study, we report the development of a highly sensitive, self-powered perovskite-based photovoltaic photodiode (PVPD) fabricated by incorporating a poly(amic acid)-polyimide (PAA-PI) copolymer as an interfacial layer between a methylammonium lead iodide (CH3NH3PbI3, MAPbI3) perovskite light-absorbing layer and a poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT: PSS) hole injection layer. The PAA-PI interfacial layer effectively suppresses carrier recombination at the interfaces, resulting in a high power conversion efficiency (PCE) of 11.8% compared to 10.4% in reference devices without an interfacial layer. Moreover, applying the PAA-PI interfacial layer to the MAPbI3 PVPD significantly improves the photodiode performance, increasing the specific detectivity by 49 times to 7.82 × 1010 Jones compared to the corresponding results of reference devices without an interfacial layer. The PAA-PI-passivated MAPbI3 PVPD also exhibits a wide linear dynamic range of ~103 dB and fast response times, with rise and decay times of 61 and 18 µs, respectively. The improved dynamic response of the PAA-PI-passivated MAPbI3 PVPD enables effective weak-light detection, highlighting the potential of advanced interfacial engineering with PAA-PI interfacial layers in the development of high-performance, self-powered perovskite photovoltaic photodetectors for a wide range of optoelectronic applications.

Authors: Jones Hannah , McClements Jake , Ray Dipa , Kalloudis Michail , Koutsos Vasileios
Published: January 2025

The phase separation of high-density polyethylene (HDPE)–polypropylene (PP) blends was studied using atomic force microscopy in tapping mode to obtain height and phase images. The results are compared with those from scanning electron microscopy imaging and are connected to the thermomechanical properties of the blends, characterised through differential scanning calorimetry, dynamic mechanical analysis (DMA), and tensile testing. Pure PP, as well as 10:90 and 20:80 weight ratio HDPE–PP blends, showed a homogeneous morphology, but the 25:75 HDPE–PP blends exhibited a sub-micrometre droplet-matrix structure, and the 50:50 HDPE–PP blends displayed a more complex co-continuous nano/microphase-separated structure. These complex phase separation morphologies correlate with the increased loss modulus (viscous properties) of the corresponding blends as measured by DMA, demonstrating the potential for the creation of strong and simultaneously tough, energy-absorbing materials for numerous applications.

Published: January 2025

Gel electrophoresis is a powerful method for the separation of nanoparticulate suspensions into several fractions with distinct particle properties. To monitor particle migration through the three-dimensional net structure of the gel and gain insights about the separation process, this study introduces a self-designed fiber-based UV-Vis measurement system equipped with five probes for the sequential in situ recording of absorption spectra. The system was employed to investigate the migration and separation of Au and Fe3O4 particles within hydrogels of varying agarose concentrations (0.15–0.50 wt.-%), revealing an increase in scattering with higher agarose content. The identification of specific particle fractions with a spherical or rod-shaped morphology was successfully achieved within the gels due to characteristic absorption peaks, allowing the real-time observation of particle separation. For the separation of a binary mixture, an adequate migration distance is needed according to the difference in the electrophoretic mobility of the two samples. The particle tracking and an additional mathematical deconvolution allowed the analysis of mixed particle samples within the gel so that their weight ratio could be determined. Finally, the system was calibrated for the determination of the particle concentration within the gel matrix, quantitatively revealing the particle concentration at a specific position in the gel.

Published: January 2025

Coal structures are commonly found in coal rock formations. Understanding the evolutionary laws of mechanics, deformation, and permeability of gas-bearing coal rock during the failure process at different bedding angles is crucial for studying the prevention and control techniques of coal and rock gas dynamic disaster mitigation. In this study, a mechanical seepage test of gas-bearing coal under various bedding angles was conducted using the fluid–solid coupling triaxial servo test system. The results indicate the following corrections: ① Both axial peak strain (ε1) and radial peak strain (ε3) initially increase and then decrease, reaching their maximum values at 45°, indicating that the specimen eventually slips along the bedding plane and fails. ② As the bedding angle increases, the peak stress of the coal body shows a “V”-shaped distribution, with the peak strength of the gas-bearing coal sample being the lowest at 60°. ③ The minimum permeability of the coal sample increases with the rise in the bedding angle. The bedding direction of the coal samples at 90° and 75° aligns with the axial direction, leading to more seepage channels. ④ At a bedding angle of 60°, the minimum dissipated energy (Ud) is required for sample failure, indicating that the sample is highly prone to failure.

Decolorization of Rhodamine B by Fenton Processes Enhanced by Cysteine and Hydroxylamine Reducers
Authors: Fernandes Ana Daura Concilia Alves , Aguiar André
Published: January 2025

Fe3+-reducing agents have been used to enhance Fenton process efficiency in degrading dyes commonly found in textile wastewater. The present work consisted of evaluating the effect of two compounds that reduce Fe3+, cysteine (Cys) and hydroxylamine (HA), on the oxidative decolorization of Rhodamine B dye by homogeneous Fenton processes, Fe2+/H2O2 and Fe3+/H2O2. The kinetics of the reactions were analyzed to better interpret the decolorization data. Due to the addition of the two reducing agents and the increase in temperature, there were increases in decolorization and the values of the reaction rate constants. The first-order reaction kinetic model was the one that best fit the experimental data. Comparing the two reducers, Cys was more effective. As an example, for reactions initially containing Fe2+ in just 20 min and at a temperature of 30 °C, the HA and Cys reducers increased the decolorization from 33% to 48% and 64%, respectively. It was possible to verify a decrease in the activation energy (Ea) due to the presence of the two reducing agents, but more significantly for reactions containing Fe3+. The values of Ea to Fe3+/H2O2, Fe3+/H2O2/Cys, and Fe3+/H2O2/HA were 85.7, 52.2, and 50.9 kJ∙mol−1, respectively. This way, it can be inferred that the two reducers decreased the energy barrier to enhance the Fenton-based oxidation of Rhodamine B.

Published: January 2025

Background: Computer-aided design/computer-aided manufacturing (CAD-CAM) technology is becoming a more significant means of providing prosthodontic treatment due to its impact on clinical performance and patient outcomes. It has been integrated into dental education to allow students to experience digital work-flows. Despite these advancements, many dental students still lack sufficient knowledge of CAD-CAM technologies. Methods: A cross-sectional survey was conducted at the College of Dentistry, Imam Abdulrahman Bin Faisal University. Based on previous studies, a validated questionnaire was distributed to undergraduate dental students and interns. The questionnaire assessed their knowledge and attitudes toward CAD-CAM technology in prosthetic dentistry. Statistical analysis software utilized in the study was the Statistical Package for Social Sciences (SPSS). Results: The responses were analyzed using descriptive statistics, and a chi-square test was used to study the association between knowledge and practice and the study year level. A total of 170 students participated in the study, with a mean age of 22.2 (±2.5) years. The proportion of female participants was 65.9% and the proportion of males was 34.1%. Knowledge varied across academic levels, with fourth- and fifth-year students demonstrating greater theoretical knowledge, while sixth-year students and interns showed more practical experience. Only 3 of the 18 knowledge-related questions received a correct response rate above 70%. Most participants (86%) reported acquiring knowledge from undergraduate courses, and 88% expressed interest in further training. Conclusions: CAD-CAM technology was most commonly practiced for fixed prostheses, and intraoral scanning was the most frequently used digital work-flow. The study highlights the need to improve CAD-CAM education. While lower-level students displayed solid theoretical knowledge, advanced students benefitted from more practical exposure. Increasing hands-on experience and access to digital equipment is essential for preparing students to meet the demands of modern digitalized dentistry.
Enhancing Precipitation Nowcasting Through Dual-Attention RNN: Integrating Satellite Infrared and Radar VIL Data
Authors: Wang Hao , Yang Rong , He Jianxin , Zeng Qiangyu , Xiong Taisong , Liu Zhihao , Jin Hongfei
Published: January 2025

Traditional deep learning-based prediction methods predominantly rely on weather radar data to quantify precipitation, often neglecting the integration of the thermal processes involved in the formation and dissipation of precipitation, which leads to reduced prediction accuracy. To address this limitation, we introduce the Dual-Attention Recurrent Neural Network (DA-RNN), a model that combines satellite infrared (IR) data with radar-derived vertically integrated liquid (VIL) content. This model leverages the fundamental physical relationship between temperature and precipitation in a predictive framework that captures thermal and water vapor dynamics, thereby enhancing prediction accuracy. The results of experimental evaluations on the SEVIR dataset demonstrate that the DA-RNN model surpasses traditional methods on the test set. Notably, the DA-TrajGRU model achieves reductions in mean squared error (MSE) and mean absolute error (MAE) of 30 (9.3%) and 89 (6.4%), respectively, compared with those of the conventional TrajGRU model. Furthermore, our DA-RNN exhibits robust false alarm rates (FAR) for various thresholds, with only slight decreases in the critical success index (CSI) and Heidke skill score (HSS) when increasing the threshold. Additionally, we present a visualization of precipitation nowcasting, illustrating that the integration of multiple data sources effectively avoids overestimation of VIL values, further increasing the precision of precipitation forecasts.
TARREAN: A Novel Transformer with a Gate Recurrent Unit for Stylized Music Generation
Authors: Zhang Yumei , Zhou Yulin , Lv Xiaojiao , Li Jinshan , Lu Heng , Su Yuping , Yang Honghong
Published: January 2025

Music generation by AI algorithms like Transformer is currently a research hotspot. Existing methods often suffer from issues related to coherence and high computational costs. To address these problems, we propose a novel Transformer-based model that incorporates a gate recurrent unit with root mean square norm restriction (TARREAN). This model improves the temporal coherence of music by utilizing the gate recurrent unit (GRU), which enhances the model’s ability to capture the dependencies between sequential elements. Additionally, we apply masked multi-head attention to prevent the model from accessing future information during training, preserving the causal structure of music sequences. To reduce computational overhead, we introduce root mean square layer normalization (RMS Norm), which smooths gradients and simplifies the calculations, thereby improving training efficiency. The music sequences are encoded using a compound word method, converting them into discrete symbol-event combinations for input into the TARREAN model. The proposed method effectively mitigates discontinuity issues in generated music and enhances generation quality. We evaluated the model using the Essen Associative Code and Folk Song Database, which contains 20,000 folk melodies from Germany, Poland, and China. The results show that our model produces music that is more aligned with human preferences, as indicated by subjective evaluation scores. The TARREAN model achieved a satisfaction score of 4.34, significantly higher than the 3.79 score of the Transformer-XL + REMI model. Objective evaluation also demonstrated a 15% improvement in temporal coherence compared to traditional methods. Both objective and subjective experimental results demonstrate that TARREAN can significantly improve generation coherence and reduce computational costs.

Published: January 2025

Background: this study builds on existing research on fathers’ experiences of family breakdown, separation, and post-separation abuse, exploring the systemic challenges they face in negotiating co-parenting arrangements. Methods: using data from a survey of 141 fathers and interviews with 30 participants, we examined the dynamics of post-separation co-parenting, particularly focusing on how fathers perceive and navigate family court systems. The data were analysed using reflexive thematic analysis to identify key themes. Results: the findings highlighted two primary themes: the difficulties that fathers face in establishing equitable co-parenting arrangements and their negative experiences with family courts, including perceptions of gender bias and systemic inefficiency. Conclusions: the results indicate a need for greater support mechanisms post-separation to facilitate healthier co-parenting relationships and minimise reliance on adversarial court processes. Furthermore, the research underscores the importance of addressing gender stereotypes within family law and social services to ensure more just outcomes for fathers and their children.
The Role of Green Innovation Appropriability and Firm Performance: Evidence from the Chinese Manufacturing Industry
Authors: Zhang Qihang , Jiang Jie
Published: January 2025

The growing concern over environmental degradation has pushed firms towards green innovation—technological progress that reduces environmental impact, especially in the manufacturing regime. In this context, appropriability, or the ability of firms to protect and profit from their innovations, particularly green technological innovation, becomes crucial. This paper investigates the role of appropriability in the relationship between green innovation and a firm’s performance and the circumstances in which that effect will be strengthened or lessened. To conduct this study, we examined 618 Chinese manufacturing firms from 2015 to 2021 and found that stronger green innovation appropriability (GIA) leads to better firm performance. Furthermore, that positive effect is superior in discrete technology regimes than in cumulative technology regimes; nonetheless, increasing the shareholding of national institutional investors can intensify GIA’s force. This study contributes to the literature on green innovation management and provides practical insight for Chinese manufacturing firms aiming to pursue sustainable production processes as well as improve their economic performance.

Published: January 2025

The acquisition, integration, and exchange of digital technologies considerably contribute to the improvement of corporate innovation quality, as autonomous vehicles are a complex amalgamation of multiple industrial chains. In order to address the intense global competition in the autonomous vehicles industry and help China’s enterprises establish a prominent position in technological innovation, this study innovatively integrates the concepts of digital empowerment, digital platform capabilities, and boundary-spanning search into a cohesive framework, examines the pathways of influence, and methodically builds a multiple-chain mediation model. It employs various quantitative models, such as reliability and validity testing, confirmatory factor analysis, common method bias testing, mediation effect analysis, and robustness testing. The study focuses on over a hundred companies related to autonomous vehicles in China, employing software such as SPSS26.0, AMOS26.0, PROCESS4.0, and MPLUS8.3 to conduct this analysis. The findings indicate that digital empowerment is a critical factor in the improvement of innovation quality within autonomous vehicle companies. The relationship between digital empowerment and innovation quality is partially mediated by digital platform capabilities, and the boundary-spanning search also functions as a partial intermediary. Additionally, the quality of innovation and digital empowerment are mediated by the boundary-spanning search and the capabilities of digital platforms. The results of this study provide valuable insights on how to accurately empower the high-quality development of the autonomous vehicle sector with digital technologies, revealing new perspectives on the innovation quality enhancement pathways for autonomous vehicle companies in China, offering pivotal insights amidst the escalating competition within the global autonomous vehicle sector.

The use of recycled manure solids (RMS) as cow bedding in dairy farms poses concerns due to its potential to harbor pathogenic and antimicrobial-resistant bacteria. This study evaluated the impact of RMS supplementation with biochar at three concentrations (2.5%, 5%, and 10%) on bacterial counts and on the antimicrobial resistance and virulence profiles of Escherichia coli and Enterococcus isolates. The results show that biochar supplementation did not promote a significant reduction in bacterial numbers. Overall, there were no significant changes in the isolates’ virulence or resistance profiles, and none of the isolates obtained were classified as high or moderate threats based on their MAR and VIR indexes. The most pathogenic Enterococcus isolates found were present in the control samples. A phylogenetic analysis of E. coli isolates allowed us to identify phylogroup D strains, predominantly in RMS supplemented with 2.5% and 10% biochar, which are associated with higher virulence and resistance. These findings indicate that the biochar concentrations tested were not effective in significantly reducing the bacterial risks associated with RMS. Further research is needed to evaluate different biochar formulations and concentrations, aiming to optimize its potential use for RMS supplementation.

Published: January 2025

Malaysia can accurately analyse flood patterns and susceptible forecast areas and allocate resources as efficiently as possible by leveraging geographic information systems (GIS). Authorities can execute data-driven plans for robust flood control and quick catastrophe response because of this technology. However, in Malaysia, public authorities adequately apply GIS, researchers often limit the use of GIS applications to study natural disasters, and communities find GIS challenging to learn and adopt. By producing flood risk mapping using GIS applications that make it easy for the communities to understand the situation, the government and communities can implement programs to mitigate the impacts of natural hazards. Reviewing the available literature on the use of GIS applications in assessing natural hazards, this study found that GIS applications effectively provide flood risk mapping and positively impact natural disaster management to ensure that the worst impacts of natural hazards can be avoided. Moreover, this study revealed the importance of GIS applications and technologies in managing natural hazards in communities to make them better prepared for disaster management. Based on the scientific research, 12 articles were identified to analyse flood management activities in Malaysia. Therefore, the government and relevant agencies should take advantage of the appropriate use of GIS in managing natural disasters and educate the population about applying GIS so that present and future generations can gain this knowledge earlier and use it better in mitigating disaster risks.

Published: January 2025

Coagulase-negative staphylococci form a heterogeneous group defined solely by the lack of coagulase. Initially considered non-pathogenic, they are now known to be opportunistic pathogens of increasing importance. This study was conducted to examine the prevalence of Staphylococcus spp., their taxonomic diversity, antibiotic resistance patterns and genetic determinants of antibiotic resistance in the water resources used within the technical snow production process. The types of samples included (1) river water at intakes where water is drawn for snowmaking, (2) water stored in technical reservoirs, from which it is pumped into the snowmaking systems, (3) and technical snowmelt water. The study was conducted in the catchments of five rivers: Białka, Biały Dunajec, Raba and Wisła in Poland, and Studený Potok in Slovakia. Staphylococcus spp. was detected in all types of samples: in 17% of river water, 25% of reservoir-stored water and in 60% of technical snowmelt water. All staphylococci were coagulase-negative (CoNS) and belonged to 10 species, with S. epidermidis being the most prevalent in river water, S. warneri and S. pasteuri in reservoir-stored water and S. haemolyticus in snowmelt water. The highest resistance rates to erythromycin and macrolide/lincosamid/streptogramin b (MLSb) types of resistance were detected in all types of samples, accompanied by the erythromycin efflux pump-determining msrA gene as the most frequent genetic determinant of antibiotic resistance. This study is the first report of the presence of antibiotic-resistant, including multidrug-resistant, CoNS carrying more than one gene determining antibiotic resistance in technical snow in the mountain areas of the Central European countries.

Published: January 2025

Tumores cardíacos fetais são extremamente raros e a maioria é benigna, sendo os mais comuns os rabdomiomas, teratomas e fibromas. O estudo tem como objetivo dimensionar as pesquisas sobre os tumores cardíacos fetais por revisão integrativa da literatura, com buscas em bases de dados entre os anos de 2020 e 2024. O processo de seleção dos estudos foi realizado seguindo as diretrizes do Preferred Reporting Items for Systematic reviews and Meta-Analyses - PRISMA Foram encontrados 10 artigos condizentes com o objetivo. 70% dos estudos são retrospectivos, 40% são de origem chinesa e somente 20% foram escritos por pesquisadores da América do Sul. O Rabdomioma Cardíaco Fetal foi bastante citado, assim como o Complexo de Esclerose Tuberosa em 30% das publicações nos anos de 2023 e 2024. A população dos estudos são fetos intrauterinos, bem como dados secundários de fetos. A avaliação cardíaca fetal é fundamental para a caracterização morfológica diferencial das massas cardíacas e para avaliação funcional cardíaca. Observa-se pouca literatura sobre a temática e ao abordar, descreve principalmente tumores cardíacos em fetos no diagnóstico pré-natal. Assim, os estudos apontam que a abordagem pré e pós-natal deve ser adequada, apresentando um risco reduzido de complicações.

A dissecção coronária espontânea (DCE) é uma condição rara, mas potencialmente grave, que pode levar a complicações como infarto do miocárdio, arritmias e morte súbita. Caracteriza-se pela ruptura na camada interna das artérias coronárias, resultando em um hematoma que compromete o fluxo sanguíneo cardíaco. Embora mais comum em mulheres jovens, a DCE pode afetar qualquer faixa etária e gênero, tornando seu diagnóstico desafiador, principalmente em pacientes sem fatores de risco típicos. Metodologia: Este estudo caracteriza-se como um Experiência de Caso, um método qualitativo e descritivo que tem como objetivo apresentar um caso específico de relevância prática, contribuindo para a compreensão e discussão de situações semelhantes. Resultados: O diagnóstico precoce é frequentemente dificultado pela semelhança dos sintomas com outras condições, como infarto agudo do miocárdio. Técnicas de imagem, como angiografia coronária e tomografia de coerência óptica (OCT), são essenciais para o diagnóstico definitivo e avaliação da extensão da lesão. O manejo da DCE varia entre tratamento conservador, intervenções percutâneas ou cirúrgicas, dependendo da gravidade da lesão. A intervenção precoce e o acompanhamento rigoroso são fundamentais para reduzir o risco de complicações graves. Conclusão: Este relato de experiência descreve o caso de uma paciente de 43 anos com DCE, abordando o diagnóstico, tratamento e acompanhamento e quais os impactos desse caso na formação acadêmica do médico. A experiência ilustra a importância de uma avaliação clínica detalhada e uma abordagem terapêutica individualizada, com base na evolução clínica do paciente, visando otimizar o prognóstico e minimizar os riscos

Published: January 2025

O Diabetes Mellitus tipo 2 (DM2) está associado a altos níveis de glicemia, fator que contribui para o desenvolvimento e progressão da disfunção renal. A Nefropatia Diabética (ND), uma complicação microvascular do DM2, caracteriza-se por albuminúria persistente e declínio da taxa de filtração glomerular (TFG), sendo uma das principais causas de Doença Renal Crônica (DRC). Este estudo teve como objetivo analisar, por meio de revisão integrativa da literatura, a relação entre hiperglicemia em pacientes com DM2 e a progressão da disfunção renal, comparando-os a pacientes não diabéticos. A metodologia incluiu busca em bases de dados como PubMed, SciELO e BVS, utilizando descritores “diabetes mellitus”, “disfunção renal” e “nefropatia diabética”. Foram analisados 21 artigos publicados entre 2020 e 2024, selecionados com base em critérios de inclusão previamente definidos. Os resultados indicaram que níveis elevados de glicemia aceleram o declínio da TFG e aumentam a albuminúria em pacientes com DM2. Além disso, intervenções como controle glicêmico rigoroso, redução da ingestão proteica e o uso de inibidores do SGLT2 mostraram-se eficazes em retardar a progressão da ND. A discussão ressaltou a interação entre fatores genéticos, clínicos e ambientais no manejo da ND, além da importância de diagnóstico precoce com marcadores como albuminúria e cistatina C. Conclui-se que a hiperglicemia é um determinante crítico na progressão da ND em pacientes com DM2, reforçando a necessidade de abordagens integradas para reduzir complicações renais e melhorar a qualidade de vida desses pacientes.

O Acidente Vascular Cerebral (AVC) é uma importante causa de morbimortalidade. O AVC isquêmico é responsável por 85% dos casos e a transformação hemorrágica (TH) é uma complicação que tem incidência de 2,2 a 8% dos casos. Identificar os fatores de risco para a transformação hemorrágica é crucial para desenvolver terapias que melhorem os desfechos. O seguinte trabalho objetiva encontrar os fatores de risco associados à TH em pacientes com acidente vascular encefálico isquêmico agudo submetidos à terapia de reperfusão. Foi realizada uma busca nas bases de dados: Pubmed, scielo e BVS, com os seguintes descritores: “risk factors”, “stroke treatment” e “hemorrhagic transformation”, utilizando o operador booleano “AND”. Utilizou-se o protocolo Prisma para guiar o screening. Com a leitura do texto completo, nove artigos foram incluídos, sendo 4 meta-análises e 5 ensaios clínicos randomizados. O NIHSS aumentado foi fator de risco comum em todos os estudos. Alguns fatores de risco independentes foram comuns à maioria dos estudos: diabetes mellitus, fibrilação atrial, tamanho do infarto, idade, glicemia à admissão e AVC prévio. A TH foi associada a um risco aumentado de mortalidade e a um pior desfecho funcional em 3 meses após o evento.

O presente relato de experiência analisa a importância do rastreamento de osteoporose, principalmente na Atenção Primária à Saúde (APS), onde é o primeiro contato da população com a saúde pública. Este relato refere-se a um atendimento médico realizado em uma Unidade Básica de Saúde. Objetiva-se compartilhar a experiência vivenciada durante um atendimento médico realizado em conjunto, em que estudantes de medicina do 5º período participaram ativamente. Destaca-se a importância do rastreamento da osteoporose na APS, fornecendo evidências práticas e contribuindo para a sensibilização dos profissionais de saúde e gestores sobre a relevância dessa abordagem na melhoria da saúde e bem-estar da população atendida. A paciente foi selecionada aleatoriamente. Durante o atendimento, foi realizada uma avaliação clínica detalhada, centrada principalmente na anamnese. Diversos fatores de risco relacionados à osteoporose foram identificados: menopausa cirúrgica precoce, diabetes melito tipo 2, uso de antidepressivos, dieta desbalanceada com baixa ingestão de cálcio e vitamina D, inatividade física e provável baixo índice de exposição solar, sendo indicado o rastreamento, com base nas diretrizes da National Osteoporosis Foundation. O rastreamento precoce da osteoporose é crucial para prevenir complicações graves, como fraturas, que podem impactar negativamente na qualidade de vida dos pacientes, especialmente idosos e mulheres na pós-menopausa. A utilização de ferramentas de triagem, principalmente a densitometria óssea, mostra-se eficaz na identificação de caso, possibilitando intervenções precoces e orientações preventivas. Este relato reforça a importância do rastreamento da osteoporose na APS como uma estratégia indispensável para a promoção da saúde e prevenção de complicações.

As artroplastias são procedimentos cirúrgicos que visam substituir os componentes articulares com danos graves por próteses artificiais para restaurar a função articular. O joelho e os quadris são as principais articulações submetidas a artroplastia, sendo a osteoartrite a principal etiologia. As infecções pós artroplastias (IPA) podem acontecer em qualquer período no pós-operatório. Objetiva-se assim, elaborar um protocolo institucional para diagnóstico precoce de infecções pós-operatórias em artroplastias de joelho e quadril, uniformizar o manejo e tratamento dos casos em consonância com a literatura científica atual, adequando-os à realidade da nossa instituição. Para tanto, foram selecionadas diretrizes nas bases de dados: MEDLINE, PUBMED, Scielo e EMBASE a partir de uma revisão sistemática. Foi utilizado AGREE II para padronizar o rigor metodológico. A flora hospitalar foi avaliada a partir dos registros da Comissão de Controle de Infecção Hospitalar (CCIH) da instituição e revisão dos resultados de cultura e antibiograma. A viabilidade das evidências e condutas foi discutida em cada setor envolvido no diagnóstico e tratamento das infecções para avaliar sua aplicabilidade. Desse modo, foram selecionadas sete diretrizes dentro dos critérios AGREE. A flora bacteriana foi representada por 49 microorganismos isolados entre 2010 e 2020. Após reunião com os setores envolvidos, os dados da literatura foram adequados à realidade prática do hospital. Sendo possível concluir com a elaboração de um protocolo institucional a partir dos dados mais aceitos na literatura e com aplicabilidade operacional da nossa instituição..
Getting your letters wrong: Early modern Epistolary writing
Authors: Bayer Gerd
Published: January 2025

Letters have played a central role in the development of various forms of literary culture. This article argues that it is through the tropes of miscarriage, deceit, and betrayal that early modern writers and audiences frequently encountered epistolary forms of communication. By looking at various examples from Renaissance and Restoration fiction and literary culture, the article demonstrates that this period was marked by inconsistencies, experimentation, and negotiations. Letters at the time provided writers with an opportunity to showcase the flexibility and malleability of language. The letter, indeed, represented the semantic in-betweenness that links factuality and fiction.

Published: January 2025

O Tumor Venéreo Transmissível (TVT) é uma neoplasia canina transmissível pelo contato direto, acomete, principalmente, animais jovens, errantes e sexualmente ativos, sendo comumente localizado na genitália externa, mucosas nasal e oral. O objetivo deste estudo foi relatar um caso atípico de TVT em cordão espermático e plexo pampiniforme. Um cão macho não castrado da raça Pit Monster, de 3 anos, foi atendido com queixa de aumento de volume na região escrotal. Após, foi realizado ultrassonografia e posterior orquiectomia com a coleta de amostras do cordão espermático e do plexo pampiniforme que foram submetidas a análises histopatológicas e imunohistoquímicas. Os resultados mostraram a presença de neoplasia de células redondas, confirmando o diagnóstico de TVT. É de extrema importância o relato de localizações atípicas de TVT, uma vez que auxilia no manejo clínico de casos futuros e, podendo ser incluído, como diagnóstico diferencial em casos de suspeita de neoplasia nestes órgãos.
A Saga do Rei Bantu
Authors: Sales Fonseca Luiz Claudio Ribeiro
Published: January 2025

O presente trabalho busca analisar os aspectos musicais e comunicacionais da canção Rei Bantu, mais especificamente a partir da regravação do cantor Jorge Du Peixe, lançada em 2021 como um single do álbum Baião Granfino. A partir de três eixos de análise, são eles: 1) performance de gosto e querelas dos fandoms; 2) mídia e nostalgia; e 3) performance e coerência expressiva, procura-se investigar de que forma a interpretação de Du Peixe articula e tensiona dimensões como modernidade e tradição a partir do seguinte corpus: 1) a música per se; e 2) o post de lançamento do single, divulgado nas redes sociais do artista. A conclusão é a de que o trabalho joga entre vertentes distintas de gosto, coadunando tradição e modernidade com a criação de um lugar entre esses dois tipos ideais.
Development of Automatic Waste Classification System using CNN-Based Deep Learning to Support Smart Waste Management
Authors: Luntungan Stephen Pieters
Published: January 2025

This research develops an automatic waste classification system using deep learning based on Convolutional Neural Network (CNN) to support the implementation of Smart Waste Management (SWM). The main objective of this research is to design and test a CNN model that is able to classify various types of waste, such as plastic, paper, organic, and other non-organic waste, with high accuracy and efficiency. The developed CNN model successfully achieved an accuracy rate of 94.86% on the training dataset. The system performed very well in classifying recyclable waste with a precision of 56.6% and recall of 63.5%, although it still faces challenges in the classification of organic waste with a precision of 45.7% and recall of 38.8%. This research also includes model validation using cross-validation techniques to ensure the generalizability of the model on different datasets. In addition, tests were conducted on external datasets to evaluate the robustness of the model under real-world conditions. Data preprocessing techniques such as image normalisation and data augmentation were used to improve the performance of the model. The results show that a CNN-based automated waste classification system has great potential to be implemented in SWM systems, enabling more efficient and automated waste management. However, there are still some challenges such as high variation in litter images and dataset limitations that need to be addressed for future development of a more robust system
