The present work deals with the study on the evaluation of the human health risks caused by the leaching of hydrocarbon products from a gas station in Sumaré-SP. First, a geoenvironmental diagnosis had to be done, where information such as: history of the area, chemicals involved, geological characteristics, transport, chemical analysis, were used to make it. The geoenvironmental diagnosis was used in the software RBCA tier 2 which established the risks by all possible pathways. The results indicated that there are risks for groundwater ingestion for commercial (on site and off site) and residential receptors and 10 that there´s risk for inhalation of vapors in enclosed space for the commercial receptor on site. The evaluation also calculated the specific target levels that the area needs to show, in order not to harm human beings and the environment. That makes RBCA a great tool that can helps the remediation actions needed to be done so that the human being and the environment remain secure.

Pipelines are linear engineering works, designed mostly for transporting oil and its derivatives for long distances, furnishing even the farthermost zones of the country. Due to oil sector needs to ensure for the safety and conservation of its properties, several geotechnical studies are being held at the pipelines field, in order to preserve this important transportation, and also to prevent accidents, which might seriously compromise the environment and the population who lives around it. The OSBRA pipeline, who connects the city of Paulínia to the capital Brasília, is one of these engineering works that deserves to be pointed out. This research, performed at the Ribeirão da Prata Basin, was a pilot study conducted with the main objective of testing the current methodology efficiency, for future applications in the closest watersheds to the OSBRA pipeline. The objective of this research is to analyze flood wave and debris flow processes in a non-fictional watershed, by comparing two different kinds of methods: the first one based on simulation models (software ‘ABC 6’), and the other one by flood wave and debris flow susceptibility mapping. The results from the hydrological modeling were both hydrographs and ietographs that estimated values of outputs and infiltration. To construct the susceptibility maps were necessary three other maps: ground use and occupation maps, divided according to the different protection degrees that were offered to the ground; maps of dam locations in the area and physiographic compartimentation maps, divided according to the local geology. To complete the methodology, the results were collected from both methods for comparison. The obtained product for this methodology was series of data whose different susceptibility degrees to flood wave and debris flow could define the safest route for a pipeline crossing in this watershed...

Among the flow, the flows have the highest destructive potential, may cause disasters with a very high number of victims, as recorded in the events Caraguatatuba (SP) and the Serra das Araras (RJ) in 1967; Valeu do Rio Figueira, in Timbé do Sul (SC) between 1995 and 1996; Vale do Itajaí in Santa Catarina, in 2008, Teresópolis, Petrópolis and Nova Friburgo (RJ), in December 2010 and January 2011. This project aimed to prioritize the main determinants of inducing processes of debris flows by applying the method of decision making AHP (Analytical Hierarch Process). Therefore, the following stages of work were defined: research of the major factors of debris flows, questionnaire design method for application of AHP expert on the subject, analysis of the results obtained from calculating the ratio of consistency and preparation of proposal for hierarchical of conditions for debris flows. From the surveys it was possible to establish a relationship of conditions according to the scale of work, defining three levels: regional (1:250,000 to 1:100,000), Semi-Detail (1:50,000 to 1:25,000) and Detail (1: 10,000 or higher). The factors found were: concentration time, the flood wave, rain, landslide susceptibility (slope), drainage and development in the deposition. The project analyzed the results obtained from the questionnaires, which allowed the ranking of the constraints, contributing to weight constraints in studies of multicriteria mapping of susceptibility to the occurrence of debris flows. The study showed that the most of the analyzed datas were inconsistent because of the different opinion of the judges

This article analyses aspects related to a continuing education course about Inclusive and Special Education in the area of Mental Disabilities offered to 20 (twenty) groups of teachers by the Ministry of Education. The Distance Course was offered in different regions of Brazil with a 180 (a hundred and eighty) hours workload. The research included the profi le of the participants, an evaluation of the course by the participants and the analysis of the dropout causes. The aspects of the course under evaluation received a positive evaluation by most of the participants. The most frequent reason for the dropout rates include participants’ limitations in terms of meeting deadlines, personal reasons and diffi culties in using computers. It was concluded that Distance Education seems to be a relevant tool for the acquisition of knowledge about inclusive practice.

With the wide variety of content to be worked out what really is expected of students in curricular physical education component? And as teachers conduct and evaluate this learning? These processes occur in the same way in public and private institutions? What is the relationship of the assessment with the students, with content and with the school? These were questions that motivated this research, which aims to conduct a desk review involving different schools, and interview their teachers, in order to identify possible relationships between teachers, students and educational institutions when referring to the assessment of physical education, between schools in different school systems (private, state and municipal), specifically from 6th to 9th grade. The survey was conducted in three different schools in the city Bauru/SP, being a private school, a school hall and a state school, and their physical education teachers. As a methodological reference was used qualitative research, and documentary analysis and semi-structured interviews were the techniques used for data collection. The data collected were tabulated and analyzed separately, and after the first analysis were separated into four categories that related to the study of literature review, interviews of teachers and the political projects of schools teaching (the documents that were analyzed). After the analysis performed it was revealed that the ways teachers surveyed perform their assessments contradicts the main problems and difficulties found in the literature. And regardless of the demands made by the educational institution that really influences the evaluation in physical education classes is the commitment and professional commitment to his students and his principles

Este trabalho teve como objetivo avaliar longitudinalmente um novo protocolo para técnica de clareamento de dentes vitais em consultório. Foram selecionados 20 pacientes, com critérios preestabelecidos, e divididos aleatoriamente, de acordo com o produto utilizado, em 2 grupos (n=10): Grupo 1 — Opalescence Xtra Boost (Ultradent); e Grupo 2 — White Gold Office (Dentsply). Os agentes clareadores foram aplicados apenas uma vez, durante 45min, e cada paciente submetido a duas sessões clareadoras. Para avaliação da cor inicial dos dentes, após 1 mês e após 3 meses do tratamento clareador, foi utilizada a escala de cor Vita Clássica, ordenada pela luminosidade. Concluiu-se que não há diferença no clareamento ou sensibilidade dentária entre os grupos, sendo desnecessária a troca do gel clareador e/ou a utilização de fonte de luz para os agentes clareadores avaliados.

The aim of this paper was to perform an energy assessment of firewood and woodshaving use for energy generation in sericulture agroindustry boilers. In this research, we used a boiler from a silk spinning factory located in the city of Duartina, São Paulo, Brazil, that currently uses eucalyptus firewood as fuel to generate water vapour used in silk fiber production. In the studied fuels utilization system energy consumption structure development, we considered energy input in Megajoule (MJ) by type, source and form involved in several firewood use technical itinerary operations, as well as in woodshaving use technical itinerary operations. From these fuels utilization built structure, we performed a firewood- and woodshaving-generated energy input comparative analysis, in Megajoule/hour (MJ.h-1), to produce 2.968,80 kg.h-1 of vapour, which is the boiler average production, during the following years: 2004, 2005, and 2006. The energy analysis results revealed that to replace eucalyptus firewood with woodshaving is something possible in the boiler, reducing total energy consumption approximately by 21%.
