The present study is the result of joint actions between education, research and outreach that is focused on the training of educators and its implications for the renovation of teaching Mathematics. Its objective is to analyze the attempts to reorganize in mathematics curriculum implemented in the state of São Paulo in the post-64. It makes use of documentary analysis and interviews of teachers for reasons of discussion and conclusions. Situated in the theoretical and methodological context of collaborative research and historical-cultural theory. The research results which shows that mathematical activity is the centrality of the discussion about learning mathematics, which has consequences for the organization, of teaching programs. This is a genesis school thinking that motivates the students to the reconstruction of ideas and thinking a production process in the classroom that considers the conditions of the school, other than the conditions that governs the production of knowledge of mathematical science, which requires thinking about the formation of a teacher epistemologically curious.

O presente relatório científico tem como proposta apresentar o processo de elaboração do livro-reportagem “As vozes que ninguém quer ouvir – Um retrato das presas estrangeiras no Brasil”, fruto do trabalho de conclusão de curso de Ana Navarrete e Juliana Santos. O livro parte da temática de mulheres vindas de outros países que são presas e cumprem pena no Brasil, para apresentar seus perfis, os motivos que as levaram ao cárcere, a vida dentro do presídio, as dificuldades jurídicas por questões de gênero e nacionalidade e a vida pós-prisão. Para isso, foram utilizados três recursos que podem compor um livro-reportagem: a grande reportagem, o perfil literário e o ensaio fotográfico jornalístico. No decorrer deste documento será apresentada a contextualização do tema, a base teórica jornalística, os objetivos, a justificativa e pretensões do trabalho, as dificuldades no processo de produção do livro e as conclusões finais das autoras. O trabalho (desde a confecção do produto, até as pesquisas e a interpretação das alunas sobre o tema) foi guiado sob a ótica dos direitos humanos. O objetivo foi dar voz a essas mulheres e levar até os leitores suas histórias, de maneira a conscientizar e incentivar debates e mudanças na situação das estrangeiras presas no Brasil

Este trabalho é uma proposta de grande reportagem para a revista Época em sua versão impressa. Diante da constatação segundo a qual a religião é assunto cada vez mais evidente na sociedade, o objetivo dessa produção é pautar um tema que é pouco difundido nos meios de comunicação de informação geral: o ecumenismo. A abordagem desse tema implicou desde a definição do conceito de ecumenismo, passando por uma breve trajetória histórica (limitações e progressos) até o relato da ação de organizações e pessoas que se envolvem concreta e cotidianamente com o ideal ecumênico. O processo de produção desse trabalho está descrito neste relatório e inclui as técnicas jornalísticas utilizadas, bem como a fundamentação teórica sobre jornalismo e sobre o tema

The term “writing media art” expresses an artisticscientific process performed in the Art-Science Communication interface presented as Final Paper in Visual Arts baccalaureate modality. The first part gathers, in artistic-scientific research, a historical overview of the relation between image and writing, which its main focus is calligraphy and its different expressions in art and design, including their interrelations. The identification is made from bibliographical and iconographical survey, both printed and virtual materials. This approach involves the selection of authors’ statements and comments in order to offer a deeper historical basis, since it comes to facts and events. The second part relates to the set of works produced during the four-year period of the Visual Arts course, including a reflection about the creation process and all that surrounds it – influences, memories, visions etc. – to finally establish a connection between all these elements in order to make clear this incredible web of creation. This work is inserted in the line of research “Artistic Processes and Procedures” of the Department of Fine Arts of the Art Institute of UNESP and describes: creative process, production and influences. The methodology used was Freinetiana Educational Cybernetics, developed in the research group “Art media and Videoclip”, whose leading advisor is the one from this Final Paper.

Escherichia coli O157:H7 is a foodborne pathogen associated with enteritis in humans, ranging from a mild to bloody diarrhea to hemolytic uremic syndrome, thrombotic thrombocytopenic purpura and even death. Large E. coli O157:H7 outbreaks have been reported worldwide and are frequently associated with consumption of undercooked beef. Cattle are a major reservoir of the pathogen, which is found in the intestinal tract of the animal. The carcasses can be contaminated with feces during the slaughter and production process. Ground beef remains the most common vehicle. The purpose of this study was to determine the E. coli O157:H7 importance associated to human illness and productivity losses to the meat industry, as well as identifying mechanisms of contamination related to beef and strategies to improve the safety of beef products

The ethyl carbamate is a compound present in most foods yeast-distillates; due to its carcinogenic potential, national legislation has established a limit of 0.150 µg / mL for spirits, so the values above the same, pose a threat to both public health as well for the economic sector by preventing the export of these products. The aim of this work is to provide the optimization of an analytical method employing the technique of gas chromatography equipped with flame ionization detector (FID) to determine the concentration levels of ethyl carbamate in some samples of wine. The use of ethyl acetate as solvent employed in the extraction, the ethyl carbamate present in wine samples proved to be suitable, where Recoveries were between 97.6 to 103.3% (m / m), with a standard deviation for between 0.56 to 3.50%. The concentrations of ethyl carbamate in particular wine samples vary between 3.22 µg / ml and 3.80 µg / mL, with a mean of 3.48 µg / mL. These valuesare all above the limit set by law. Thus, the results indicate the need for changes in the process of wine production, in order to control the levels of the substance

Therebar of aluminum 1350 AA produced by CBA are used inthe manufacture of wires and cables for electric power transmission, which marketshows increasingly favorableto aluminum due to itslow densityand high electrical conductivity, but to ensure that this materialmeets all specifications of projectsfor electricity transmission, it must have homogeneity in the chemicaland mechanicalproperties.One of the points of improvement in the process of rod production isreducing the high variation of the limitof tensile strengthalong the coils, therefore, this work seeks a better understanding of the factors that significantly influence the mechanical properties of rebar, specifically assessing the influence oftemperatureat the output of the coils, which can cause a recovery effect on the material andif thereare relevantdifferences between the two modes of rebar production: auto and manual.Samples of six coils have been specifically produced forthis study, which weresubsequently subjected to different annealing temperatures for one hour and ten minutes, similar to what occurs in the output of the coil from the machine. The tensile tests showed that aluminum 1350 AA is significantly influenced by temperature, whose behavior was very similar to that presented in the literature. It was found that the phenomenon of recovery occurred more significantly at high temperatures. Through the optical electron microscope Zeiss, 18 surface maps were made with 100x magnification for each sample in different conditions and the images were analyzed using entropy and fractal dimension, aiming to relate the condition of surface hardening on mechanical property of the samples in that condition. The results showed that these methods can be applied, provided they do not have any kind of imperfection on the surface, once they can influence the results. The study concluded that a more efficient cooling is required in ... (Complete abstract click electronic access below)
