Entre o "instinto" e a "falta de hábito": a psiquiatrização da sexualidade em Bom-Crioulo (1895)

A productive dialogue marked the interaction among novelists and scientists adepts from deterministic theories in the late 19th century. We start with the contextualization of this fundamental period to history of sexuality in modern societies to realize analytical reading of Adolfo Caminha s novel, Bom-Crioulo (1895). The projects that based discourses in this period answered to the question of homoerotism like social and medical matter. In this work, we discuss like this biopolitical reading in Brazilian society was elaborated in Caminha s novel and from the jurist Francisco Viveiros de Castro, defining it in accordance with Brazilian racism.
Investigação por espectroscopia Mössbauer das fases formadas e sua influência na resistência à corrosão do aço inoxidável austenítico AISI 316L nitretado
(Universidade Federal de São Carlos, 2009-03-10) Campos, Marcelo; Souza, Maristela Olzon Monteiro Dionysio de; https://lattes.cnpq.br/9452239672967881; https://lattes.cnpq.br/0717563036484228
The plasma nitriding is a technique that improves mechanical and tribological properties of metallic materials as hardness and wear. It improves also the corrosion resistance, because the nitrated layer is formed by phases as the metastable phase (γN), iron nitrides (ε-Fe2-3N and γ -Fe4N) and chrome nitrides. In recent paper studying nitrided AISI 316L stainless steel, we proposed an empiric model to explain the observed results: The higher the ε/γ ratio, better the corrosion resistance is. In order to test this model systematically, we produced samples with ε/γ ratio different values. So, AISI 316L stainless steel samples were nitrided under dc glow discharge, 80 vol. % H2 and 20 vol. % N2 gas mixture, at different conditions of temperature (350º, 400º and 450º C) and time intervals (3, 4 and 5 h). The produced samples were analyzed by X-Ray Diffraction and Mössbauer Spectroscopy, in order to identify the phases presents in the surface layers. The layer thickness was measured by SEM (Scanning Electric Microscope). Besides Hardness Vickers measurements, corrosion performance of the samples was investigated in 3% NaCl aerated electrolytic solution. The present results could not be explained by the first empiric model. Then we proposed a new model: The sample that presents the minimum value for (fórmula) will resist better to corrosion. Besides to explain the presents results, this new model is successful with the previous results. The best condition of treatment was temperature of 400º C, during 4 h, because it produces a sample that presented the best corrosion resistance and a good hardness value.
