Determinação de manganêsem águas no entorno de minerações de urânio

The studies of this work aimed to determine the labile fractions of manganese (Mn) in natural and drainage water samples collected around the Osamu Utsumi uranium mine, located in the municipality of Caldas, south-central region of Poços de Caldas- MG, using the technique of diffusion gradient in thin films (DGT). The DGT devices were mounted with Chelex-100 resin, polyacrylamide-agarose hydrogel (conventional porosity) and cellulose acetate membrane. The device were deployed up to 48 hours in six water samples collected from different areas around the uranium mine (075, 076, 022-E, 025-E, 014, and 041). The DGT devices immersed in each sample were gradually removed after 4, 8, 12, 24 and 48 hours. The pH of the samples ranged from 3.0 to 10.5, which influenced the lability and the sampling of the analyte by the Chelex-100 resin. The results showed a linear relationship between accumulated mass and sampling time (immersion curve) for samples 014 and 025-E (pH between 6 and 8) suggesting the ability of the DGT technique for sampling the analyte. The results obtained for samples 075 and 076 (pH<5) and samples 041 and 022-E (pH around 10) were characterized by nonlinear relationships. The values obtained by DGT were compared with Solid Phase Extraction (SPE) technique using Chelex-100. For samples 014 and 025-E, there was a good agreement between the results obtained by both techniques

Estudo da deformação heterogênea no ensaio do anel de atrito

The plastic deformation is widely used in the metallurgical market due to its positive factors such as low prices and high speed production. Forming process products are obtained in high quality, both surface quality and mechanical properties. Friction is an importante factor in metal forming. Friction study in metal forming can be accomplished indirectly, such as the ring test of friction. Two samples of different materials being mild steel and copper alloy were used. The results showed the influence of friction in the flow behavior of the deformation of the second phase, as evidenced by standard metallography. It is observed that in the outer regions of the ring, plastic deformation occured in the radial direction. In the central region of the disc deformation occured in the direction of compression and the inner region of the ring flux lines showed a significant deformation in the radial direction towards the center of the ring

Experimentação no ensino de física: um estudo escolas estaduais na região de São José dos Campos

This work presents the results of a study on the use of experimentation in physics teaching, presenting a survey on the use of this strategy in public high schools in the region of São José dos Campos. Data collection was carried out in schools by means of questionnaires prepared for physics teachers and students from three grades of high school. Data were obtained in eighteen schools distributed in the city of São José dos Campos (two in the central region, in the west, three on the east side, seven in the north and five in the south), a school in the district of Sao Francisco Xavier and a school in the town of Monteiro Lobato. Thus, data from 20 schools, 610 students and 20 teachers were analyzed. Among the main results, we highlight that over 80% of the students said that there is no physics lab at the school where they study, and less than 1% declares that uses laboratory weekly. We note that there is a laboratory in 25% of the schools in the northern region and 10% or less of the other schools. According to the students the proposition of the experimental activities by teachers is rare - only three schools in East Side the options sometimes and always exceeded the number of responses experimental activities are never proposed. We had 60% of the teachers who reported using the curriculum of the state of São Paulo to propose activities to students, and half of the teachers said they did not have classes experimental physics classes in initial training or had them in sufficient quantity to support the use of this feature in practice
