Purpose this study aims to analyze the association between motivation to learn and adaptation to the ERT of students in the 9th year of Elementary School and 1st, 2nd and 3rd years of High School in a privately funded institution. Methods this is an observational, analytical and cross-sectional study, in which 68 adolescents participated, authorized by their parents, who answered three questionnaires through the Google Forms platform, namely: Questionnaire for the Characterization of Participants; Learning Motivation Scale (EMAPRE) and Remote Learning Adaptation Questionnaire. Results the association analysis showed that students with high motivation felt better adapted to the ERT. In addition, it showed that girls with low motivation were more inclined to avoid negative situations than boys. Conclusion it was concluded that intrinsic motivation may have influenced the adaptation to ERT and that girls may have been motivated to avoid school failure in a way that didn’t harm their personal emotional issues.
Geotextile tubes are generally used in hydraulic and marine applications such as coastal protection and flood control. They are also used to dewater sludge from sewage treatment plants and dredged materials. Studies have been carried out to derive analytical solutions and develop empirical models as well as numerical simulations to represent the behaviour of geotextile tubes in such applications. However, there has been insufficient attention on dewatering of mining tailings. This article presents the numerical results of modelling a geotextile tube using Abaqus, a commercially available finite element software package. The mechanical behaviour of the tube was simulated while it was being filled with gold mining tailings. Back analyses of a large-scale field test as well as parametric analyses were performed to evaluate the influence of filling pressure, elastic modulus and finite element type on the stress–strain behaviour of the geotextile tube. In terms of validation, the numerical results agreed well with the analytical results and field test observations. A smaller elastic modulus causes greater strain. Comparing the results obtained using different types of finite elements, it was observed that the membrane element used to simulate the geotextile tube represented its mechanical behaviour well.
The water retention curves (WRC) presented in this study were determined for materials constituting prototypes of evapotranspirative capillary barrier coverage, which used gneissic residual soil and non-woven geotextile. The determination of the WRC was made possible by the hanging column test for the two distinct non-woven geotextiles and the hanging column and filter paper tests for the residual soil. Both tests were executed with both the drying and wetting trajectories. The curves were adjusted and the hydraulic conductivity functions were estimated, thus enabling a greater understanding of the hydraulic behavior of the materials involved. The non-woven geotextiles and residual soil presented WRC, as expected, similar to the WRC presented in the literature for similar materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
