The increasing rate of traffic accidents, followed by the high rate of mortality due to these occurrences, favored to the classification of traffic accidents as a public health problem in Brazil. These accidents consume a significant portion of Gross Domestic Product (GDP), especially related to the victims. Considering this scenery with many tragedies and resources being spent only in the end, this paper seeks to examine the influence of federal highways lighting by reducing the number of accidents. Federal Highways sections that received lighting were taken up for study, therefore a survey of statistical data has been raised considering the accidents before and after the route had been illuminated. Taking advantage of the results obtained, an economic analysis has been made considering the amounts consumed by traffic accidents versus the values required for the installation of lighting on highways

The aim of this paper is to present some fundamental aspects of the history of the number e, in particular those related to its origin, a little uncertain, and their unavoidable presence in the most diverse applications in various branches of science. We will highlight the importance of this number in compound interest problems, in the Napier’s logarithms, in the quadrature of the hyperbola, in the catenary problem and mostly in the lush Euler’s contribution to the subject.

In this work was developed a fuzzy computational model type-2 predictive interval, using the software of the type-2 fuzzy MATLAB toolbox, the final idea is to estimate the number of hospitalizations of patients with respiratory diseases. The interest in the creation of this model is to assist in decision makeshift hospital environment, where there are no medical or professional equipment available to provide the care that the population need. It began working with the study of fuzzy logic, the fuzzy inference system and fuzzy toolbox. Through a real database provided by the Departamento de Informática do Sistema Único de Saúde (DATASUS) and Companhia de Tecnologia de Saneamento Básico (CETESB), was possible to start the model. The analyzed database is composed of the number of patients admitted with respiratory diseases a day for the public hospital in São José dos Campos, during the year 2009 and by factors such as PM10, SO2, wind and humidity. These factors were analyzed as input variables and, through these, is possible to get the number of admissions a day, which is the output variable of the model. For data analysis we used the fuzzy control method type-2 Mamdani. In the following steps the performance developed in this work was compared with the performance of the same model using fuzzy logic type-1. Finally, the validity of the models was estimated by the ROC curve

Neste artigo, apresentamos os resultados de um estudo que investigou o que as pesquisas dos Programas de Pós-Graduação em Educação do Estado de São Paulo produzidas entre 1980 e 2005, com foco nas práticas de professores alfabetizadores, dizem a respeito dos procedimentos, práticas e saberes que caracterizam a atuação desses docentes. Primeiramente, fazemos uma breve contextualização da alfabetização. Em seguida, destacamos a análise do corpus (8 teses e 32 dissertações) nos focos temáticos: procedimentos de alfabetização, práticas docentes e saberes docentes. Os dados apresentados neste artigo permitem apontar permanências e indícios de alterações nas práticas dos alfabetizadores e, consequentemente, nas pesquisas sobre essas práticas.

The aim of this study was to compare the hydraulic conductance in human dentin disks, where 1, 2 or 3 layers of adhesive Single Bond 2(SB2) and Single Bond Universal(SBU) were applied. 84 1 mm. thick(+/- 0.1 mm.) dentin disks were fabricated. Samples were divided into 7 groups (n = 12) Control (without adhesive), A1: one layer of SB2, A2: two layers SB2, A3: three layers SB2, B1: one layer SBU, B2: two layers of SBU, B3: three layers of SBU. The results as averages for the hydraulic conductance of each separate group were: Control (0.0363), A1 (0.0206), A2 (0.0070), A3 (0.0061), B1 (0.0161), B2 (0.0062), B3(0.0056) expressed µl/min.cm2. There is statistically significant difference CH, between the control group and those samples that one coat was applied (p = 0.000) and also between the application of one and two layers (p = 0.000). No difference between the two adhesives (p = 0.434). Summary Key words: Dentin, conductance, difussion adhesive layers.
