The purpose of this research is to show the types of violence committed by teachers that were experienced and/or witnessed by future teachers during their schooling history. It's a quantitative and qualitative research. The collection, organization, and analysis of data proceeded from Content Analysis (BARDIN, 1977) and the construction of Bernard Charlot and Pierre Bourdieu's works and specific literature on the theme. The subjects are 12 students that attended the Pedagogy undergraduate program in 2011 at the Faculty of Science and Arts of the city of Araraquara in the state of São Paulo, Brazil. The data shows that the majority of the group of individuals claimed to have witnessed or experienced violence by teachers during their basic training. According to them, among the most recurring types of violence are those of symbolic nature. They attended, not equally, the public system and the private system. This enabled pointing out that violence, especially symbolic violence, occurred in both school systems. Therefore, this is a phenomenon that affects different fractions of social classes. Considering that the participants of this research are future teachers, it was established a relation with the notion of 'cycle of abuse', since there is a high possibility of them practicing the teaching function.

The approach of the subject matter in this work relies on the fact that the reliability of methods for performance analysis of materials proves critical for the result. This work focused on the development and presentation of the methodology for lifting probability curves for fatigue test (SN) according to standard E739, this focus is justified by the fact that the results in fatigue test show considerable dispersion making it difficult to reading and interpretation of data, this dispersion arises because the phenomenon of rupture is strongly influenced by internal characteristics of the material, we can then have much data ranging from test to test. Thus we set out originally for a brief study of aluminum alloys in question, as well as the treatments to which they were subjected. We also studied the behavior of materials when subjected to cyclic loading, which configures process of fatigue failure, and even fatigue test method in question. This statistical analysis is based on the ASTM E739 standard, so its contents was studied in detail so that we could present in detail the methodology and raise SN curves for different aluminum alloy 7012 subjected to fatigue test. Data were collected from tests conducted in the department of materials from two samples of aluminum alloy 7012 solubilized and precipitated by different time intervals and assayed temperature fatigue-type traction-compression, these data were then analyzed and used to survey curves using the base as E739. After lifting the curve analyzed the characteristics of the test samples and their correlation with the test results. We confirmed the effectiveness of the method of statistical analysis by ASME E739, which allowed the reading of data without this method would be very difficult to have a reading and comparison of the results for the two types...

Partindo do pressuposto que risco é um conceito central na sociedade contemporânea, este estudo teve por objetivo entender o papel da mídia na circulação e consolidação da linguagem dos riscos. Tendo por base estudos anteriores, optou-se por trabalhar com um único jornal, a Folha de S. Paulo, sendo adotados três procedimentos de pesquisa: 1) mapeamento da diversidade de termos utilizados para falar sobre a possibilidade de ocorrência de eventos concebidos como ocasião para ganho ou perda; 2) análise diacrônica de uma amostra representativa de matérias com a palavra risco no título (1921 e 1998); 3) análise do uso da linguagem de risco por área temática (CD-Rom Folha, 1994-1997). Os resultados sugerem que o uso da linguagem dos riscos na mídia é recente e diversificado, apoiando-se ora na linguagem formal do cálculo de risco, ora no uso metafórico do termo, para falar de desordem na sociedade contemporânea.

In questo elaborato si esplora ed estende la teoria sugli spazi di funzioni spline generalizzate utili nell'ambito della modellazione geometrica. In particolare si è analizzata la vasta letteratura e i diversi frammentati approcci, provenienti da paesi e epoche differenti con lo scopo di definire una teoria unica e completa effettivamente utilizzabile nelle applicazioni, in particolare nell'ambito della modellazione geometrica. In questo ambiente infatti lo spazio spline in cui si decide di lavorare deve necessariamente possedere una base con ben precise proprietà, sulle quali si focalizza la nostra trattazione. Supportati dalla sperimentazione numerica e simbolica, abbiamo dimostrato la proprietà di Variation Diminishing e trovato diversi spazi spline con le caratteristiche volute.
