Imageamento Elétrico 3D em área contaminada por hidrocarbonetono polo industrial de Cubatão - SP

Este trabalho mostra os resultados obtidos com ensaios geofísicos realizados em uma área contaminada por hidrocarboneto no Polo Industrial de Cubatão - São Paulo, com objetivo de caracterizar as anomalias geoelétricas associadas à presença dos hidrocarbonetos, bem como delimitar e cubar tais anomalias. Para tanto, utilizou-se o método da eletrorresistividade, por meio das técnicas de Sondagem Elétrica Vertical (SEV) e Imageamento Elétrico 3D. Os resultados obtidos permitem indicar que a presença de hidrocarboneto está associada a anomalias condutivas devido aos produtos da biodegradação. As anomalias condutivas ocorrem de forma disseminada na área, totalizando um volume de 1365,3 m³; entretanto, este volume corresponde somente à presença de contaminante em fase residual.

Evaluation of neighborhood impacts caused by companies of the high-tech industrial cluster of São Carlos, SP, Brazil

The purpose of this study was to develop a methodology for evaluating neighborhood impacts using a Geographic Information System (GIS) and to apply the procedures to the companies of the High-Technology Industrial Cluster of São Carlos. To this end, an evaluation was made of the neighborhood impacts on the physical environment, urban components, quality of life, and urban infrastructure using impact matrices, and the impacts were assigned scores according to type, order, magnitude and duration. Fifty one companies were examined based on data provided by the companies themselves and on field surveys. The impacts are represented spatially in proportional symbols maps, based on the spatial distribution of the companies in the urban area of the city of São Carlos and the areas of influence of each company. The application of the proposed methodology served to validate it and indicated that the neighborhood impacts caused by the companies of this study are related to each company's type of activity, its size, and its occupation of the area. © 2008 Journal of Urban and Environmental Engineering (JUEE).

Ideologia industrial x cultura rural: o método SESI de ensino em uma escola rural

This study compares two educational practices: the Rural School method (Escola do Campo) and the SESI teaching method, suggesting that the latter one is inefficient when applied to rural schools, as illustrated with a case study of a rural school that was obliged to adopt this method in 2012. The epistemological basis of a dialogical pedagogy for rural education has been used in order to criticize the practices of a method whose origins in the industrial ideology and in consumerism promotes a true cultural invasion, according to Paulo Freire, hindering the students' dialogues with respect to the ways of life in rural areas and in towns – an interaction that assured school performance in the previous educational system, which has been arbitrarily discontinued by the political power. Different surveys were used in this study for both compared cases, specially dissertations that have evaluated the Rural School project (Projeto Escola do Campo), adopted in Araraquara in 2004, a dissertation about the SESI teaching method that has discussed its new didactic material and, also, an evaluation of the contents of a representative sample of textbooks of History, Geography, Sciences and Mathematics for the 6th grade of elementary school. It is a theoretical text, not an essay, considering that it is based on concrete situations, which were explained using researches on the implicit themes and summarizes the analytical procedures that have allowed to unveil, in the textbooks prepared by SESI, the stimulus and the valorization of consumerism, without any criticism and environment concerns.
