One of the issues related to the construction and consolidation of a truly inclusive school concerns the importance of teachers, their valorization and their training, both initial and continued in the form of graduate specialization, update courses and short term courses. The objective of this work, considering the above context, was to determine whether teachers' conceptions of Portuguese, referring to his deaf students, have been changed after attending a continuing education course entitled Portuguese Language for the Deaf. The study was conducted at a Board of Education located in the central region of São Paulo State, which offered the course in the period 2004 to 2008, and focused on the year 2005. Study participants were 33 teachers who took part of course in Portuguese Language for the Deaf in 2005 and responded to assessments of the same period. The research, which consisted of a study of descriptive and exploratory qualitative approach was used to document analysis and semistructured interviews. Data analysis employed the procedures of content analysis. The writings of the teachers revealed some misconceptions about deafness, the deaf students and their learning. They also revealed the contributions of the course concerned that these contributions have been revised. The survey also offered some reflections on the issues surrounding the initial training and continuing education, the complexity of teaching Portuguese for the deaf and the points that could be improved in the course examination.
Avaliação da corrosão intergranular de aços inoxidáveis por meio de normas e de ensaios eletroquímicos em altos potenciais
(Universidade Federal de São Carlos, 2011-04-04) Higa, Silvia Midori; Kuri, Sebastião Elias; https://lattes.cnpq.br/6842072916153866; https://lattes.cnpq.br/7245298285401456
The corrosion resistance of stainless steels is given by the formation of a Cr2O3 film on the metal surface, inhibiting its contact with the aggressive medium. The sensitization that occurs in these steels at temperatures ranging from 500 to 800°C is responsible for corrosion due to carbide precipitation at grain boundaries, which makes the adjacent regions depleted of chromium. The standards used in industries to assess the stainless steels in their susceptibility to corrosion is based on immersion tests followed by microstructural analysis. The electrochemical tests provide a deeper analysis of the degree of sensitization that is often not detected by tests of immersion. This study aimed to evaluate the different techniques to determine the susceptibility to localized corrosion, pitting and intergranular in stainless steels to sensitization at different temperatures and compare them with current standards. Were used austenitic stainless steel AISI 304, AISI 304L, AISI 316L and martensitic stainless steel AISI 420. The evaluation of corrosion was carried out by potentiodynamic reactivation tests and double-loop cyclic anodic polarization, besides the classification according to the criteria of ASTM A 262 practice A. The electrochemical tests have provided a further analysis based on the standard immersion tests. The degree of sensitization obtained in the electrochemical tests showed an impairment of corrosion resistance of stainless steels, which, according to the criteria of the standard would be accepted for susceptibility to intergranular corrosion.
