Published: December 2024

Introduction: Vesicouterine fistula, also known as Youssef’s syndrome, is a rare but significant complication primarily arising after cesarean sections. This condition involves an abnormal connection between the bladder and the uterus, which can lead to symptoms such as cyclic hematuria (menstrual blood in the urine) and urinary leakage. The increasing incidence of cesarean deliveries highlights the need for greater awareness and effective management of this condition.

Case Report: We present the case of a 32-year-old woman with a history of multiple cesarean sections who was admitted with spontaneous labor at 36 weeks and 4 days of amenorrhea. Initial diagnostic imaging and clinical assessment indicated a viable pregnancy but revealed a history of extensive intra-abdominal adhesions. During an emergency cesarean section, complications included a bladder injury and a 2 cm uterine rupture. Post-operatively, the persistent presence of hematuria led to further investigation using retrograde urethrocystography (UCR), which confirmed the diagnosis of a vesicouterine fistula. The diagnosis of vesicouterine fistula presents significant challenges due to its rarity and the overlap of symptoms with other conditions such as malignancies or bladder injuries. The condition is often associated with difficult cesarean sections and extensive intra-abdominal adhesions. Accurate diagnosis relies on imaging techniques, particularly UCR, to identify the fistula and guide appropriate surgical intervention. Effective management includes careful surgical repair and post-operative monitoring to resolve the fistula and restore normal bladder and uterine function.

Conclusion: Vesicouterine fistula is a rare but important complication following cesarean sections, requiring prompt recognition, and management. Awareness of its symptoms and the potential for occurrence in patients with a history of multiple cesarean deliveries is essential for early diagnosis. Imaging modalities, such as UCR, are crucial for accurate diagnosis and guiding surgical treatment. Early intervention and careful post-operative care are key to achieving favorable outcomes and preserving reproductive health.

Articulando noções da história das cidades, história da arte pública, morfologia urbana e urbanismo crítico, este artigo aproxima dois projetos de arte que se inserem no escopo das ausências e memória nas cidades contemporâneas. De um lado, uma cidade que via o mar de sua janela, antes que sucessivos aterramentos afastassem o mar até que ele se perdesse na paisagem. A cidade do Rio de Janeiro, em continuados processos de transformações urbanas, viu suas feições transmutarem ao limite do não-reconhecimento. O projeto de Guga Ferraz (Até onde o mar vinha, até onde o Rio ia, 2014) refaz simbolicamente as linhas de toque entre o mar e a cidade do Rio de Janeiro, desaparecidas no início da década de 1920.
Na outra ponta, um projeto de arte pública que recria, em sua forma arquitetural mais simplificada, aquilo que foi vida para uma comunidade que saudava a alegria de viver no Píer 52, às margens do Hudson River, Nova York. A obra Day´s End (2014-2021), do artista estadunidense David Hammons, redesenha na memória e nos espaços etéreos que pairam entre rio, cidade e horizonte, os traços do armazém à beira-rio que, suprimido da paisagem, sobrevive em suas linhas fantasmáticas.
Cada qual à sua maneira, os trabalhos de Guga Ferraz e David Hammons parecem replicar, em sua fantasmagoria, o abandono de cidades aviltadas por sucessivos processos de gentrificação.

O passageiro fecha os olhos. De um lado está sentada uma criança agitada, do outro uma pequena janela por onde se vêm as nuvens. Os pais da criança irão esforçar-se (ou não) por mantê-la “presa” à cadeira durante as 7 horas da viagem que se avizinha. O enclausuramento e proximidade forçada testa os limites da resistência humana. O espaço interior de um avião tenta manter a lógica dos ambientes e acções à cota 0, entre elas está, obviamente a sã convivência. Começa por ser difícil sentá-los e depois mantê-los sentados1: o ambiente está montado. Para o nosso artigo elegemos um conjunto de objectos presentes a bordo dos aviões da TAP Portugal que tentaram amenizar ou condicionar a atitude das crianças e juvenis durante o arco temporal das décadas de sessenta a oitenta. Objectos, que parecendo inócuos, possuem a simultaneidade funcional de evitar o choro e a birra, entretendo e distraindo, e estender a experiência e valores da marca. A nostalgia das viagens realizadas em família durante este período está povoada de recordações dessas ofertas que marcaram gerações de crianças, hoje adultos, talvez colecionadores.

Published: November 2024

Background: The necessity for efficient medication optimization techniques has increased due to the rising incidence of chronic illnesses in older populations. Despite being frequently required, polypharmacy carries a number of serious dangers, such as decreased quality of life, adverse drug events (ADEs), and prescription non-adherence. An interdisciplinary platform for tackling these issues is provided by telehealth, a quickly developing digital innovation that combines the knowledge of pharmaceutical and nursing specialists. Aim: this study is to investigate how telemedicine can improve medication optimization in geriatric care by fostering interdisciplinary cooperation between pharmacy and nursing specialists. In order to provide a strong framework for future practices, it examines evidence-based solutions, ethical issues, and implementation challenges. Methods: Studies assessing telemedicine solutions for medication optimization were the main topic of a systematic evaluation of recent literature (2010–2018). Alongside qualitative information about interdisciplinary cooperation and ethical issues, quantitative data on outcomes including medication adherence, ADE decrease, and patient satisfaction were examined. Results: Telehealth dramatically increases medication adherence and lowers adverse drug events (ADEs) among older patients. Pharmacy professionals help with medication reconciliation and adherence assistance, while nursing professionals are essential in patient monitoring, education, and empowerment.

Background: By compromising the effectiveness of life-saving therapies and driving up healthcare expenses, antibiotic resistance (AR) is a serious danger to global public health. Effective mitigation solutions are desperately needed, as the World Health Organization (WHO) has declared AR a high global health concern. As frontline healthcare professionals, nurses and pharmacists have distinct and complementary roles in antimicrobial stewardship (AMS). Their capacity to have a collaborative impact is still untapped, though. Aim: this research is to analyze the multidisciplinary cooperation between pharmacy and nursing in tackling AR, emphasizing how well it works to improve patient outcomes, lower resistance rates, and strengthen AMS programs. The research highlights obstacles, investigates facilitators, and offers practical suggestions for incorporating these functions into a unified approach to counter AR. Methods: To better understand interdisciplinary approaches to AR management, a thematic assessment of peer-reviewed literature, clinical guidelines, and case studies was carried out. To find trends of cooperation, common difficulties, and proof of achievement, data were combined. Results: By optimizing antibiotic use, enhancing patient education, and guaranteeing adherence to infection control guidelines, interdisciplinary collaboration between nursing and pharmacy improves AMS.

Partiendo del apócrifo “antropología mexicana” el artículo cuestiona su institucionalización, en tanto residual del campo disciplinario, así como su sistema consuetudinario.
En aras de interpretar “lo mexicano” en sus significados corrientes, recurre a los artificios culturales de la lucha libre y rock que también son reclamados y se ostentan como tales. Revisando históricamente el desarrollo de ambas industrias culturales ofrece el contraste para revelar al mediador evanescente en la relación entre Estado y sujetos de mexicanidad en distintos momentos generacionales, así como los “abusos por costumbre” en un entramado disciplinario institucional del presente. En él se opone al cosmopolitanismo inherente a la disciplina el nacionalismo con que se marginaliza a la disidencia.

Published: December 2024

Este trabajo está dirigido al fortalecimiento del pensamiento y de la práctica (praxis) de la evaluación educadora que lideran los docentes a nivel áulico (micro). Presenta las diferencias entre la denominada evaluación educativa y la evaluación educadora, siendo esta última la alternativa didáctica para que los estudiantes se conviertan en auto y socio didactas a lo largo de todas sus vidas, además, de situar a la evaluación como el eje vertebrador del proceso educador y de aprendizaje personal y grupal.Se establecen las diferencias entre evaluación del aprendizaje y de la educación, en el entendido de que el aprendizaje no necesariamente es educativo y que la misma evaluación sí no es asumida por los educandos de manera concientizadora puede convertirse en una práctica alienante y hasta deformadora del educando, de los docentes y de sus culturas educacionales, haciéndola un estorbo y hasta un obstáculo, para la consecución de mejores niveles de calidad de la educación misma y de los respectivos aprendizajes implicados.El trabajo termina exponiendo los lineamientos genéricos acerca del cómo practicar la Evaluación Educadora o educante a nivel áulico en un esfuerzo por hacer de este proceso un recurso didáctico para estudiantes y profesores, integrado en forma directa a la consecución cualitativa, más que cuantitativa, de objetivos educacionales formativos y didáctico-instructivos, propios de la educación, mientras se aleja de otros modos de hacer la micro - evaluación con fines administrativos, políticos y/o de control. Es pertinente resaltar que la evaluación es, más que la medición; esta última es solo un recurso de la primera y adquiere sentido educativo, si y solo si contribuye al desarrollo estudiantil.

Published: November 2024

Introdução: Os estudos epidemiológicos sobre inflamação pancreática repentina são comumente baseados em pesquisas internacionais ou com faixas etárias elevadas. O objetivo deste trabalho é entender quais fatores determinam a ocorrência de internação de jovens brasileiros por pancreatite aguda. Métodos: Trata-se de um estudo epidemiológico, transversal, observacional, retrospectivo, quantitativo, analítico e descritivo. Os dados de indivíduos de 15 a 29 anos foram coletados no Sistema de Informações Hospitalares do SUS (SIH/SUS). Analisou-se o número absoluto de internações e as incidências médias. Resultados: No Brasil houveram 27.731 internações de jovens, com uma tendência sutil de crescimento de 2018 a 2023. O Sudeste e Nordeste apresentaram valores superiores e o estado de São Paulo a maior frequência de registros. As regiões com a maior incidência média foram o Sul, Sudeste e Centro-Oeste e as menores incidências anuais ocorreram em 2018, no Nordeste e Norte. O sexo feminino foi predominante em internações e incidência. A maioria eram pardos, e somente em São Paulo, Paraná, Santa Catarina e Rio Grande do Sul a população branca foi a mais acometida. Discussão: As internações por região podem ser explicadas pelas divergências quanto à quantidade de habitantes e as incidências podem estar atreladas ao padrão regional de consumo de bebidas alcoólicas. A maior ocorrência em mulheres pode acontecer devido à litíase biliar e ao aumento do consumo alcoólico nos últimos anos. Esse consumo apresenta tendência crescente em ambos gêneros, porém efeitos deletérios são superiores no feminino. Os dados quanto à raça condizem com o a população do país, já que pardos são maioria no Norte, Nordeste e Centro-Oeste, superada pela população branca somente nas regiões restantes. Conclusão: Jovens foram amplamente acometidos pela condição em todas as regiões brasileiras. Os resultados deste trabalho podem contribuir para a criação de políticas que visem mudar a atual situação epidemiológica.

Published: November 2024

Advances in information technology have led to significant changes in the teaching and learning process, enabling traditional face-to-face methods to be replaced or supplemented by online meetings. Social media, designed initially for social interaction and entertainment, has increasingly become a tool for sharing educational content, including language learning. While prior studies have demonstrated the potential of social media for academic purposes, there is a gap in research focusing on maritime cadets' use of social media for learning English. This study examines cadets’ perspectives in the Port and Shipping Management department on using social media for English learning. This research employs a descriptive qualitative approach. Data was collected via online surveys. Among the 89 respondents, all were active social media users, and 85 reported using these platforms, primarily Instagram, YouTube, and TikTok, for language learning. The cadets expressed interest in developing speaking, reading, writing, and listening skills. However, the study also identified challenges, including internet connectivity issues and entertainment content distractions. These findings suggest that while social media provides valuable language learning resources, obstacles must be addressed to optimize its effectiveness as an educational tool. English lecturers can combine learning in class by utilizing content provided by existing social media accounts.

Many schools still use manual recording in borrowing and returning and there is no automation of library reports resulting in many lost books that cannot be traced. In addition, manual recording also risks not recording library materials because of the many borrowers who come. Library digitization training using the SliM application for 6 vocational schools where 4 vocational schools are in Tangerang district, 1 vocational school is in Karawang and 1 vocational school is in Malingping. The six vocational schools until the day of the training had not used the library application and were still using a conventional system by recording borrowing and returning books through a ledger although 3 schools had recorded books in Microsoft Excel but for borrowing and returning they still used manual. So it is necessary to conduct training in the use of the library application so that library materials owned by the school can be traced easily and databased and make it easier to print reports. The training was conducted at the Saba Karya Insan Pembangunan Auditorium with competent speakers, namely guided directly by librarians and Insan Pembangunan University itself has long implemented the SLiM application. Participants from 6 vocational schools were very enthusiastic in participating in this training and communication media was provided for participants if they still experienced problems using the application
Comparative analysis of the fine-grained quartz textures from ain temouchent beaches and adrar sand dunes in Algeria
Authors: Dahmani Roqiya , Bouskaia Tahar , Amer Lakhder , Bradai Hamza , Ouahab Ali , Hadjira Rafai
Published: November 2024

This research endeavors to scrutinize the microtextures of quartz grains obtained from two distinct regions in Algeria: the beaches of Ain Temouchent Province along the Mediterranean coast and the sand dunes of Adrar Province in the southern part of the country. The analysis focuses on examining the shape and size of the quartz grains, with particular attention to the smooth texture of the surfaces. Quartz grains from both coastal and desert regions exhibit an angular to sub-circular shape, indicating diverse and heterogeneous origins with short to medium transport processes. Notably, differences emerge in the mechanical features present on the surfaces of these quartz grains, allowing for the differentiation and partial prediction of their respective environments. Mechanical signs such as percussion marks (Pm), V-shaped marks (Vs), parallel striations (Ps), meandering ridges (Mr), bulged edges (ble), crystal overgrowths (Cro), and rough terrain are prevalent on grains from the beaches of Ain Temouchent Province, indicating a high-energy beach environment. Conversely, quartz grains from the Adrar region exhibit abundant features such as grain-to-grain impact (CK), meandering ridges (Mr), bulged edges (ble), and smooth surfaces, signifying exposure to strong air currents and facilitating the transportation of grains over considerable distances, contributing to erosion processes in the area. This comprehensive analysis provides valuable insights into the geological history and sedimentary processes of the coastal and sand dune environments in Algeria.
An improved multi-band spectral subtraction technique designed for cochlear implant users
Authors: Boucherit Ismail , Amokrane Zouhir , Mohamed Ould Zmirli , Kebir Sofiane Tchoketch
Published: November 2024

In this paper, we propose a novel approach to reduce noise in cochlear implants by utilizing an enhanced multi-band spectral subtraction method. The main objective of this work is to optimize the subtraction factors used in the spectral subtraction process to improve the overall performance of the stimulation strategy in cochlear implants. These implants are designed to decompose incoming audio signals into multiple sub-bands for further processing. However, one of the persistent challenges in cochlear implant technology is maintaining speech intelligibility in noisy environments. To address this issue, our approach involves adapting the subtraction factors dynamically based on common noise patterns observed in real-world scenarios. To assess the effectiveness of this method, we conducted extensive simulations using noisy sentences corrupted by eight distinct types of environmental noise, including street noise, machinery, and crowd chatter. Objective evaluations were performed using established metrics for speech intelligibility and audio quality. The results demonstrate that our proposed method significantly enhances the signal-to-noise ratio, ensuring improved clarity of speech for users of cochlear implants. This approach is highly promising, as evidenced by the encouraging results obtained in our simulations. By enabling more precise signal processing, it contributes to better speech intelligibility and overall user satisfaction.

Published: November 2024

Magnesium and cadmium oxides (MgO, CdO) are widely used in optoelectronic technology, and CdxMg1-xO oxides exhibit an interesting band gap. For this reason, they are a significant subject of research. In this work, the structural and elastic properties of rock-salt CdxMg1-xO were investigated using two exchange-correlation functionals (LDA and GGA-WC). The calculations were performed using the Full-Potential Linearized Augmented Plane Wave (FP-LAPW) method within the framework of Density Functional Theory (DFT). The lattice parameter was Calculated for various cadmium concentrations (x) in the rock-salt structure, showing a quasi-linear variation from 4.257 A° for MgO to 4.43 A° for CdO. With deviations of less than 1%, the calculated values was in good agreement with experimental data for both rs-MgO and rs-CdO. In addition, the three independent elastic constants were computed, together with associated parameters including bulk modulus, shear modulus, and Young's modulus for CdxMg1-xO in the rock-salt structure. The quasi-linear change in the elastic characteristics is also evident, with the values of C11, C12, and C44 for rs-MgO changing from 334.85, 94.84, and 98.28 to 242.88, 124, and 48.08 for rs-CdO, respectively.

Published: November 2024

The Chatter vibrations are a critical issue in milling, affecting workpiece quality and potentially damaging machines. This study analyzes the causes of chatter and proposes preventive methods. After reviewing the existing research, the transfer function is analyzed using an orthogonal cutting model, highlighting its evolution concerning system stability. A dynamic stability map is developed to help select optimal spindle speeds and cutting depths. Experiments using an innovative chatter detection device, based on noise analysis, demonstrate real-time identification of chatter, enhancing operational stability. The second part focuses on modeling cutting forces, essential for optimizing machining conditions and mitigating vibrations. A thermo-mechanical approach is applied using the Abaqus simulator and the Arbitrary Lagrangian-Eulerian (ALE) method to study the impact of cutting conditions on mechanical stress and temperature at the tool-workpiece interface. The results show that cutting parameters significantly influence both stress distribution and thermal behavior.

The generalized gradient approximation GGA, GGA + U, where U is the Hubbard potential U and Tran–Blaha-modified Becke–Johnson (TB-mBJ–GGA) potential have been used to calculate the ground-state response of SrYO3 (Y= V; Cr and Fe) Perovskite Oxides. For this purpose, we use the full-potential linearized augmented plane wave method along with the spin-polarized calculations implemented in WIEN2k simulation code. The optimization curves of the three compounds confirm their stable structures. The mechanical stability is achieved through the calculation of the elastic parameters. A strong elastic anisotropy for the   three compounds is depicted. SrVO3, SrCrO3 are ductile but SrFeO3 is brittle. Moreover, the electronic properties are calculated using Band Structure and Density of States, SrVO3 and SrFeO3 are metallic using GGA but half metallic with GGA+U and TB-mBJ–GGA.SrCrO3 is half metallic for the three approximations.We can also note that P type conductivity is observed for SrCrO3 and SrFeO3 and N type conductivity for SrVO3. The total magnetic moments of all compounds are integers which confirm their half metallicity with a 100% spin polarization, which makes them promising candidates for spintronic and embedded system applications. The contribution of Y atoms is dominant to the overall magnetic behavior of alloys. The thermoelectric characteristics are also elaborated such us thermal conductivity and Seebeck coefficient, within the temperature range 300-1000K. We can observe that SrCrO3 and SrFeO3 show promising thermoelectric properties with significant figure of merit ZT values of 1 at room temperature.

This work aims to evaluate the operational processes and performance of industrial diffusion flame burners. Specifically, the study focuses on the interaction between multiple jets and their influence on the dynamic and thermal characteristics of the flow field, flame stability, and the resulting flow field composition within the combustion chamber. The investigation was carried out on three industrial gas burners, each with a capacity of 250 kilowatts. Numerical simulations were performed using the FLUENT software, incorporating the standard k-ε turbulence model coupled with the Eddy Dissipation (ED) model for turbulent combustion. This approach allowed for a detailed analysis of the complex flow and combustion processes occurring within the burners. The results demonstrate that the structure of the flow field, as well as the shape and stability of the flame, are significantly affected by the geometry of the burner and the mode of operation. These findings provide valuable insights for optimizing burner design and improving combustion efficiency.

In recent years, image compression methods are the important research topics, these methods are classified into reversible and irreversiblet techniques.  The irreversible techniques or called transformation techniques are the most widely used today. In fact, the transformation methods decompose the image into an orthonormal basis, such as a great number of the coefficients be equal to zero, without significantly impairing the visual aspect of the original image. Decades ago, the wavelet theory has given high contributions in the transformation methods by its nice mathematical properties and using the traditional thresholding as Hard and soft thresholding. However, if the image has a large singularity, we will be obliged to increase the number of non-zero wavelet coefficients in the reconstructed image. So, this situation costs us a lot, especially with color images. Therefore, we can pose the following problem to answer: are there thresholding operators can reduce the wavelet coefficients number independently on the singularity contained in the image?. In this paper, we propose a new method for image compression, called Comparative Thresholding (CT), which is based on constructing new thresholding operators that solve the imposed compression problem. These solution operators can enhance the traditional thresholding in terms of the visual quality of the compressed image. Experiments on a grayscale image using Discrete Wavelet Transform (DWT) with our proposed method (CT), show that CT method provides better performance compared to traditional thresholding in terms of the Peak Signal to Noise Ratio (PSNR) and Compression Ratio (CR).

A videira é um fruto que tem seu crescimento e desenvolvimento vegetativo afetado por diversos elementos meteorológicos do clima. Telas de sombreamento diminuem a incidência solar e ajuda a controlar o microclima. Alguns tipos de malhas, além do sombreamento, apresenta funções extras como melhorar a distribuição da luminosidade ou estimular o crescimento das plantas. O presente trabalho objetiva analisar a influência do uso de telas de sombreamento sobre o cultivo de uvas na região sudoeste do estado de São Paulo. O experimento contou com o uso de malhas negra, aluminizada e vermelha sobre o cultivar Benitaka. Uma parcela a céu aberto foi analisado para comparação com os tratamentos sob telado. Foram tomados dados de crescimento vegetativo da folha, qualidade e quantidade de produção de frutos, bem como, seu teor de açúcar. Médias estatísticas sobre os resultados e mostraram que a malha vermelha apresentou bons índices de produção vegetal sobre as demais parcelas. Conclui-se que, para a região do sudoeste paulista, a produção de uvas apresenta melhores índices quando tratados sob telado vermelho. Malhas negras e aluminizadas apresentaram índices de produção abaixo do tratamento a céu aberto.

Um bilhão de pessoas vivem com transtornos mentais, sendo essa a principal causa de incapacidade em todo o mundo. No norte de Minas Gerais, cerca de 30% da população utiliza a bicicleta, o que justifica intervenções nas vias para garantir mais segurança a esse público. Diante desse cenário, é essencial investigar os efeitos do ciclismo sobre a saúde mental. O presente estudo objetivou apresentar o perfil sociodemográfico e clínico de ciclistas e não ciclistas do Norte de Minas Gerais e sua associação com a ocorrência de sintomas de estresse, ansiedade e depressão. É um estudo de natureza analítica, transversal e quantitativa, que examinou aspectos sociodemográficos, esportivos e clínicos de ciclistas e não ciclistas na região Norte de Minas Gerais. Participaram da pesquisa 245 não ciclistas e 233 ciclistas. Foi aplicado o questionário DASS-21 para avaliar os níveis de estresse, ansiedade e depressão. Constatou-se que indivíduos mais jovens apresentaram maior chance de quadros moderados a graves de depressão (RC=0,977) e estresse (RC=0,976), enquanto o sexo feminino foi associado a maiores chances de depressão (RC=2,352) e ansiedade (RC=2,321). Para ansiedade, também houve maior chance entre não casados (RC=3,284) e não ciclistas (RC=3,008). Conclui-se que são válidos projetos de conscientização para a prática do esporte, visto que esse possui impacto na prevenção de transtornos mentais graves e ameaçadoras à vida. Ademais, é notória a necessidade de intervenções para reduzir a carga da depressão e do estresse em jovens.

As sub-bacias dos rios São Francisco e São Francisco Falso destacam-se como áreas de grande potencial para a piscicultura, com grande parte de sua extensão situada acima de 300 metros de altitude. A implantação de propriedades para criação de peixes nessas áreas exige estudos prévios com Sistemas de Informações Geográficas (SIG). Este trabalho teve como objetivo caracterizar as sub-bacias usando o software QGIS para avaliar a viabilidade aquícola na região. Foram analisados fatores como hidrografia, hipsometria, declividades, solos, clima e uso do solo. As sub-bacias próximas à Usina Hidrelétrica Itaipu Binacional possuem hidrografia sem risco de enchentes e altitudes variando de 219 m a 763 m, com relevos suavemente ondulados. A sub-bacia do São Francisco Falso apresenta solo Nitossolo Vermelho e Neossolo Regolítico, enquanto o São Francisco possui Nitossolo Vermelho e Latossolo Vermelho. As sub-bacias dos rios São Francisco e São Francisco Falso possuem condições morfológicas e morfométricas favoráveis para o desenvolvimento da piscicultura em viveiros escavados.
