Modified technical protocol for single-port laparoscopic appendectomy using needle-type grasping forceps for acute simple appendicitis: A case report
Authors: Chen Yang , Fan Zong-Qi , Fu Xin-Ao , Zhang Xiao-Xin , Yuan Jie-Qing , Guo Shi-Gang 
Published: September 2024

BACKGROUND
Because of the mild inflammatory status in acute uncomplicated appendicitis, our team developed a novel technical protocol for single-port laparoscopic appendectomy using needle-type grasping forceps (SLAN) and achieved positive clinical outcomes. However, the intraoperative procedure lacked stability and fluency due to a series of problems highlighted by the small incision design of the protocol (only 1 cm long). Therefore, there is a growing clinical demand to further optimize the SLAN protocol.
CASE SUMMARY
An adult male patient was admitted for persistent right lower abdominal pain with preoperative computed tomography findings suggestive of appendicitis accompanied by localized peritonitis. A modified technical protocol for SLAN based on minimally invasive surgical principles was used, and the patient was confirmed to have acute simple appendicitis by postoperative pathological analysis. Postoperative recovery was uneventful, and no postoperative complications, such as incision infection or severe incision pain, were observed. The patient was discharged successfully on postoperative day 2.
CONCLUSION
The modified technical protocol of SLAN may be a new minimally invasive surgical alternative for patients with acute simple appendicitis.

An adult mule was presented with a purulent wound on the distal and medial third of the pastern of his right forelimb (MAD) accompanied by grade 5 lameness. A type II fracture of the third phalanx (P3) was diagnosed by radiological examination. Treatment consisted of analgesics, antibiotics, wound care and a flanged boot bandage, replaced by a Monkey splint the following week. Six (6) months later, a follow-up clinical examination showed a clear reduction in lameness estimated at grade 2 and a clear reduction in pain on palpation.

Objetivo: Identificar la relación estadística entre las variables OCB, la satisfacción del personal y la retención entre los trabajadores del milenio utilizando ecuaciones estructurales. Diseño metodológico: Una encuesta transversal que utiliza cuestionarios con 385 millennials de la región de Laja-Bajio en México. El cuestionario se validó utilizando el análisis factorial y el modelo se validó utilizando ecuaciones estructurales. Ambos análisis produjeron resultados satisfactorios según los estándares estadísticos aceptados. Resultados: Existe una relación positiva entre el comportamiento de la ciudadanía organizacional individual y colectiva, y esto afecta la satisfacción laboral y la retención de los trabajadores milenarios. No se estudió el vínculo entre el comportamiento de la ciudadanía personal y la satisfacción laboral. Limitaciones de investigación: El estudio se centra únicamente en el vínculo entre OCB y la satisfacción/retención de empleados del Milenio. El estudio debe incluir otras variables como justicia organizacional, rasgos personales y productividad percibida. Es vital expandirlo a otras regiones mexicanas. Recomendaciones: El comportamiento de la ciudadanía organizacional ayuda a explicar por qué los millennials permanecen en el trabajo. Este hallazgo apoya la literatura internacional sobre el comportamiento de los trabajadores y su impacto en el trabajo.

Un arbre en ce monde. Théodore de Bèze, moraliste du contemptus mundi
Authors: Barioz Alain-Cyril 
Published: September 2024

Inspirés par les idées de détachement et de renoncement, les thèmes cléricaux et monastiques du contemptus mundi dénoncent la richesse, la chair et la gloire comme autant d’obstacles dans la quête de Dieu. Ils devaient, cependant, être renouvelés à la faveur de sa réception humaniste tandis que la Réforme, de son côté, avait besoin d’une doctrine du mépris du monde qui lui soit propre. La façon dont ce topos est transformé par Théodore Bèze au XVIe siècle pour devenir un thème majeur chez les réformateurs permet de comprendre leur « imaginaire » à partir des mentalités, de l’anthropologie culturelle et de la théorie de la réception. Via les genres littéraires à sa disposition, Bèze favorise une reconfiguration du contemptus mundi à partir des traditions médiévales et classiques. Son itinéraire commence à Orléans dans le contexte de la poésie latine humaniste et de l’évangélisme, ainsi que dans les bouleversements provoqués par les persécutions. Sa conversion au calvinisme le conduit à l’exil. La reformulation du mépris du monde à travers ses thèmes de prédilection comme la conversion, les normes et la discipline des Églises, les confessions de foi, la sanctification, l’eschatologie, la méditation sur la mort et la vanité de ce monde… s’est traduite par une large diffusion du motif à travers de nouveaux genres et médias. Bèze a joué un grand rôle dans l’adoption d’une conception éthique personnelle d’une attitude chrétienne droite à adopter face au théâtre d’un monde en mutation. Cette reconfiguration du mépris du monde est devenue constitutive du rayonnement calviniste en Europe.
Évolution du tai chi à la lumière de l’émersiologie
Authors: Kurashima Akira 
Published: September 2024

L’article explore le tai chi, art martial d’origine chinoise aujourd’hui majoritairement suivi pour ses bienfaits sur la santé et ses implications spirituelles. Notre intérêt porte sur le fait que l’entraînement à des « formes », une série de mouvements exécutés en solitaire, souvent lentement, s’observe non seulement dans la plupart des écoles focalisées sur la santé, mais aussi dans une minorité portée sur l’aspect martial. Pour analyser le rôle des formes dans l’apprentissage des techniques de combat, l’article s’appuie sur l’émersiologie, l’étude de l’activation involontaire du corps, permettant la focalisation sur les éléments propices à la transformation du schéma corporel. Cette analyse vise à concilier la dichotomie entre le tai chi comme art martial, de combat, et sa pratique à des fins de santé, apportant une meilleure compréhension de l’évolution historique du tai chi.
ANÁLISE TEMPORAL DE MUDANÇAS NO ECOSSISTEMA DE DUNAS DO DISTRITO DE QUINTÃO, PALMARES DO SUL - RS

Published: September 2024

RESUMO - As áreas costeiras, sujeitas a mudanças constantes devido a ações erosivas, deposicionais e antrópicas, enfrentam desafios físicos e ecossistêmicos significativos. A mudança do uso e cobertura do solo amplia a perda de habitats cruciais, como dunas, essenciais para serviços ecossistêmicos de proteção costeira. O presente trabalho tem por objetivo realizar uma análise temporal de mudanças no ecossistema de dunas do distrito de Quintão. Para isso, foram selecionadas imagens Landsat de diferentes períodos e analisadas as mudanças obtidas através da classificação semi automática das imagens. A partir da classificação, os dados foram inseridos no modelo Land Change Modeler no software TerrSet 2020 onde foram elaborados os mapas de transição, de mudança e de persistência das classes ao longo do período de análise. Os resultados obtidos indicam um aumento de 993% na área urbana no distrito. Já as áreas de dunas apresentaram uma diminuição em sua área de 34,45%. Diante das alterações ambientais identificadas decorrentes do crescimento urbano, propõe-se a implementação de um monitoramento contínuo da supressão de ambientes naturais em Quintão. Essa medida visa não apenas à preservação das dunas como parte fundamental do ecossistema costeiro, mas também a mitigação dos impactos negativos associados ao avanço urbano desordenado.

ABSTRACT - Coastal areas, subject to constant changes due to erosive, depositional, and anthropic actions, face significant physical and ecosystem challenges. The change in land use and coverage exacerbates the loss of crucial habitats, such as dunes, essential for coastal protection ecosystem services. The aim of this study is to conduct a temporal analysis of changes in the dune ecosystem in the Quintão district. To achieve this, Landsat images from different periods were selected, and changes were analyzed through the semi-automatic classification of the images. Following the classification, the data were input into the Land Change Modeler in the TerrSet 2020 software, where transition, change, and persistence maps of the classes were developed over the analysis period. The results indicate a 993% increase in urban area in the district. Conversely, dune areas experienced a decrease in their extent by 34.45%. Given the identified environmental changes resulting from urban growth, the continuous monitoring of the suppression of natural environments in Quintão is proposed. This measure aims not only at preserving dunes as a fundamental part of the coastal ecosystem but also at mitigating the negative impacts associated with disordered urban advancement.

RESUMO - As Aeronaves Remotamente Pilotadas (do inglês Remotely Piloted Aircraft – RPA), popularmente conhecidas como Drone, vêm sendo amplamente utilizadas na mineração, cujo cenário competitivo requer otimização do desempenho operacional aliado a custos atrativos. Buscando entender como uma RPA pode auxiliar na realização de estudos na prospecção e exploração mineral, o presente trabalho utilizou essa ferramenta para realizar um aerolevantamento em uma área com potencial para exploração do minério de ferro, localizada no Quadrilátero Ferrífero, Minas Gerais. O objetivo foi avaliar os produtos gerados por um drone da linha consumidor como suporte à prospecção mineral. Especificamente, objetivou-se avaliar se esses produtos favorecem a uma melhor e mais assertiva caracterização geológica e geomorfológica da região, se comparado aos dados espaciais disponíveis, no contexto da prospecção e exploração mineral. Para isso, foram gerados Ortomosaico, Modelo Digital de Terreno (MDT) e Modelo 3D Texturizado. Os resultados permitiram identificar com maior clareza as principais feições geológicas e geomorfológicas e, portanto, o drone se mostrou como uma interessante ferramenta complementar para os trabalhos de prospecção e exploração mineral, sendo destacados ganhos de eficiência e custos competitivos em relação aos levantamentos convencionais de campo.

ABSTRACT - Remotely Piloted Aircraft (RPA), popularly known as Drones, have been widely used in mining, whose competitive scenario requires operational performance optimization combined with attractive costs. Aiming to understand how an RPA can assist in carrying out studies in mineral prospecting and exploration, this study used this tool to perform an aerial survey in an area with potential for iron ore exploration, located in the Quadrilátero Ferrífero, Minas Gerais. The objective was to evaluate the products generated by a consumer-grade drone as support for mineral prospecting. Specifically, the aim was to assess whether these products favor a better and more assertive geological and geomorphological characterization of the region, when compared to the available spatial data, in the context of mineral prospecting and exploration. For this, an Orthomosaic, Digital Terrain Model (DTM), and Textured 3D Model were generated. The results allowed for the identification of the main geological and geomorphological features with greater clarity and, therefore, the drone proved to be an interesting complementary tool for prospecting and mineral exploration work, highlighting efficiency gains and competitive costs to conventional field surveys.

Впервые получены новые зависимости и взаимосвязи при реализации технологии абразивостойкой наплавки на термоупрочненную сталь 65Г. Выявлен характер распределения твердости по Виккерсу в вертикальном и горизонтальном направлениях области наплавки и показана их идентичность. Установлено, что термические воздействия от сварочной дуги снижают твердость основного металла, расположенного непосредственно в нижней части области наплавки. Показано, что влияние термических воздействий на твердость металла и размеры зоны термического влияния и околошовной зоны больше проявляется по глубине области наплавки по сравнению с плоскостным направлением. Дано объяснение изменений твердости HV в различных зонах на основе материаловедения, металлургии и последних исследований в области прочности.
For the first time, new dependencies and relationships were obtained in the implementation of the technology of abrasion-resistant surfacing on heat-strengthened steel 65G. The nature of the Vickers hardness distribution in the vertical and horizontal directions of the surfacing area is revealed and their identity is shown. It has been found that thermal effects from the welding arc reduce the hardness of the base metal located directly in the lower part of the surfacing area. It is shown that the influence of thermal influences on the hardness of the metal and the size of the zone of thermal influence and the near-seam zone is more pronounced in the depth of the surfacing area compared with the planar direction. An explanation of the changes in HV hardness in various zones is given based on materials science, metallurgy and recent strength studies.

В статье представлены результаты коррозионных испытаний кобальта в атмосферных условиях при различных температурно-влажностных режимах. Показано, что коррозионные потери кобальта при температурах 20, 30 °С и относительной влажности воздуха 70, 80, 95% незначительны. Скорость коррозии кобальта при температуре воздуха 50 °С резко возрастает, особенно при относительной влажности воздуха 95%. Об интенсивном протекании коррозионных процессов на кобальте в этих условиях свидетельствует и внешний вид образцов кобальта: после испытаний при температуре 50 °С и влажности воздуха 70% образцы чернеют, а при температуре 50 °С и влажности воздуха 95% покрываются черными, маслянистыми, легко осыпающимися хлопьями – продуктами коррозии кобальта. Установлено, что на поверхности кобальта образуется коррозионная пленка, состоящая из эвтектической смеси Co–CoO переменного состава и сложного оксида CoO·Co(OH)2·H2O. При повышении температуры коррозионных испытаний поверхностная пленка гидратированного оксида кобальта увеличивает свою толщину, покрывается микротрещинами, формируются хлопья гидроксида кобальта, которые слабо сцепляются с подложкой и осыпаются.
The paper presents results of cobalt corrosion test on the air at different temperatures and humidity values. It was demonstrated that corrosion losses in Co samples at 20, 30 °С and relative humidity of 70, 80, 95% are insignificant, but its corrosion velocity is sharply increased at 50 °С especially at 95% relative humidity. One can also judge the intensity of corrosion processes by the look of the samples: the samples turn black at 50 °С, humidity 70%, and at 50 °С, 95% they are covered with black, oily, easily crumbling flakes – products of cobalt corrosion. It was found that corrosion film on the cobalt surface has a complicated structure that includes the Co–CoO eutectic mixture of variable composition and the complex oxide CoO·Co(OH)2·H2O. With an increase in the corrosion tests temperature, the surface film of hydrated cobalt oxide comes thicker, it becomes covered with microcracks, than flakes of cobalt hydroxide with weakly adhesion to the substrate, and then they deteriorate.
