Contextualiza e descreve o trabalho desenvolvido pela equipe da UNESP de Araraquara no município de Axixá do Tocantins durante o Projeto Rondon. Apresenta proposta multidisciplinar desenvolvida e voltada para os anos finais do Ensino Fundamental e Ensino Médio, entendendo-se que a rede municipal de ensino constitui-se num espaço estratégico para desencadear processos formativos que possam atingir, direta ou indiretamente, o público escolar e população em contato com esta. Focando a Serra do Estrondo, patrimônio natural local, a proposta objetiva a articulação de conhecimentos teóricos e práticos a partir de conteúdos relacionados à temática ambiental para enfrentamento de problemas socioambientais.

This article reports on the diversity and the linguistic variations in e-mails and chat interactions in teletandem interactions. Based on the interface of foreign language acquisition and sociolinguistics, its focus is on linguistic variants under the perspective of the social variations of language, especially regarding standard and non-standard norms of the Portuguese language in a teletandem context. Sociolinguistics offers us resources for the analysis and understanding that we intend to provide about teletandem interactions. We also mention the Teletandem Brasil project, its ideas and theoretical orientations, and also analyze data collected. The findings show that the variations in foreign students´ written production, who are also Portuguese learners, come from fluctuations between the standard and non-standard norms because students still do not have complete communicative competence in the target language.

The aim of this experience report is to present the Semiotic Studies Lab for Patient Care Interactions (Laboratório de Estudos Semióticos nas Interações de Cuidado - LESIC). The lab was set up at the Nursing School of the Federal University of Rio Grande do Sul (UFRGS), Brazil, in 2010. It has the purpose of providing didactic and pedagogical updates, based on the Theory developed by the Paris School of Semiotics, that enable the increase of knowledge and interactive/observational skills regarding the nature and mastery of human care.

This article provides reflections and discussions about the importance of human interactions and methodological interrelations to substantiate the integrity in the transdisciplinary process in teams that operate in health area. Should be taken as reference the Complexity Theory of Edgar Morin, the logic transdisciplinary of Basarab Nicolescu and the formation groups principles based on the Socionomic Theory of Jacob Levy Moreno. It was concluded that the complexity of the methodologies in the field of workplace health, are influenced by factors that intersect between the scientific interaction and human interrelationships, which allow the transdisciplinary construction. However, the constructions requires the development of professionals in their areas and in their relationship with others as a way of supporting the perspective of transdisciplinarity, ie, interaction, in which different individuals are interrelated with the methodologies and providing articulations and coconstructions from which actualize the transformations.

The development of electrocatalysts for the oxidation of methanol and ethanol is very important, because these alcohols may be used in the anode fuel cells which convert chemical energy directly into electrical energy with high efficiency, cleanly and with low noise. Thus, this study reports to the synthesis of nanocatalysts of PtAu supported on carbon by microemulsion method. The physical characterization of these catalysts is performed through the techniques of X-ray diffraction and transmission electron microscopy. The catalytic activity of the prepared materials was studied using conventional electrochemical techniques and also the technique of spectro-electrochemical in situ FTIR, which allows identification of intermediates and products of the reactions. From the x-ray diffraction, it was observed that the thermal treatment applied to catalysts favored incorporation of Au into the crystal lattice of Pt,that is, increased the formation of PtAu alloy. Micrographs indicated particle size about 3 nm to materials not heat treated and 9 nm to materials subjected to thermal treatment (heating at 150 ° C for 1h and 30 min in argon atmosphere). Current density oxidation of methanol on PtAu / C were superior to pure platinum. Spectroscopic results indicated the presence of formate in solution in 50:50 and the composition showed bands for CO2, indicating complete oxidation, in lower potential. During ethanol oxidation on the catalyst PtAu, the main product formed was acetate, product of incomplete oxidation. The good performance for methanol oxidation can be attributed to large amounts of oxygen species adsorbed on the catalyst surface, or an electronic effect.
