Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Determination of the behavior of steel fiber reinforced concrete beams without stirrups under bending by nonlinear finite element analysis

WOS: 000436191100006Although the use of steel fiber reinforced concrete elements is on the rise in recent years, present analytical models to determine the structural behavior of these members are inadequate, requiring numerical methods such as nonlinear finite element method. In this study, two steel fiber reinforced concrete beam and one ordinary reinforced concrete beam tested under static three-point bending were modeled with a Modified Compression Field Theory based nonlinear finite element method and results were investigated. In the method, Simplified Diverse Embedment Model was selected to model the tensile stresses transmitted between crack faces in cracked concrete. When analysis results were compared with experimental results, it was observed that the bending capacities and major cracks were captured with high accuracy, whereas displacement capacities were highly underpredicted. Although the major cracks were predicted with high accuracy, the fact that the model could not predict smaller cracks accurately and, as a result, the occurrence of a premature reinforcing bar failure at major cracks is believed to be the major reason for earlier failure of beams. More advanced models are needed for modeling the steel fiber reinforcement in order to obtain more accurate solutions

Continuous serratus posterior superior intercostal plane block for postoperative analgesia management in the patient who underwent right atrial mass excision: a case report

Abstract Serratus posterior intercostal plane block (SPSIPB) is a novel periparavertebral block. It provides anterolateral posterior chest wall analgesia. It is an interfascial plane block, performed under ultrasound guidance, and the visualization of landmarks is easy. It is performed deep into the serratus posterior superior muscle at the level of the third rib. Until now, there have been case reports about the usage of single-shot SPSIPB, but there are no reports about the usage of the block catheterization technique of SPSIPB. Continuous infusion from a catheter of interfascial plane blocks is important for postoperative analgesia management after painful surgeries such as thoracic and cardiac surgeries. Thus, we performed SPSIPB catheterization in a patient who underwent right atrial mass excision with minimally invasive thoracotomy surgery. Here, we present our successful analgesic experience with continuous SPSIPB in this case report
