This work aims to study the fluctuation structure of physical properties of oil well profiles. It was used as technique the analysis of fluctuations without trend (Detrended Fluctuation Analysis - DFA). It has been made part of the study 54 oil wells in the Campo de Namorado located in the Campos Basin in Rio de Janeiro. We studied five sections, namely: sonic, density, porosity, resistivity and gamma rays. For most of the profiles , DFA analysis was available in the literature, though the sonic perfile was estimated with the aid of a standard algorithm. The comparison between the exponents of DFA of the five profiles was performed using linear correlation of variables, so we had 10 comparisons of profiles. Our null hypothesis is that the values of DFA for the various physical properties are independent. The main result indicates that no refutation of the null hypothesis. That is, the fluctuations observed by DFA in the profiles do not have a universal character, that is, in general the quantities display a floating structure of their own. From the ten correlations studied only the profiles of density and sonic one showed a significant correlation (p> 0.05). Finally these results indicate that one should use the data from DFA with caution, because, in general, based on geological analysis DFA different profiles can lead to disparate conclusions

O Partido Comunista (1922-1962): lugar de memória, espaço de disputa

This work studies the dispute by Party Communist s memory in Brazil during and after division which it resulted in the appearance of two parties entitled communists, in the brazilian political context, in the final of the fifties and beginning of the sixties: the Brazilian Communist Party (in Portuguese, Partido Comunista Brasileiro) and the Communist Party of Brazil (in portuguese, Partido Comunista do Brasil). Along of yours three chapters, the author tries to answer some questions as: what were the elements which constituted the Communist Party s memory, in the period from 1922 to 1956? At which moment did this memory pass to be fiercely contested? Who and which documents reveal this? How did it happen the dispute by this memory? The approach to topic consider which the production of memory by Communist Party and the dispute for your possession by communists of PCB and of PCdoB happened in scope of national reality and of party, spaces notions understand from concept of memory developed for authors as Halbwachs, Le Goff, Pollack and Pierre Nora. To explain the objectives of historical research it has used as methodology the exam and the interpretation of documentary and bibliographical sources, with priority for the party s documents then it was depicted a collective interpretation about the events considered more importants. The sites of Partido Comunista do Brasil (www.pcdob.org.br or vermelho.org.br) and of Partido Popular Socialista (www.pps.org.br) also went consulted

"Ombro a ombro com os mais fracos": a inserção de João Café Filho nos espaços do trabalhador na cidade do Natal 1922 - 1937

The purpose of this thesis is to analyze how João Café Filho constituted a discourse of advocate of the labor movement and workers in different sociability spaces. It is intended to understand, on one hand, how political relations were established between different categories of workers and the ‘middle classes’ and, on the other hand, how places were instituted to house the meeting of these relations. It a ims to understand the insertion of Café Filho in union activities in the urban world. It demonstrates specificities of the political culture in Natal emphasizing the dispute between a city politically ruled by a still reigning rural paternalistic mentality and the rise of a new way to experience the urban conflicts which appeared. Temporally, the work is delimited between 1922 (proclaimed by Café Filho himself as the initial period of his political action) and 1937 (when he broke up with Vargas and went into exile in Argentina). The research was constituted by three main document types: several published newspapers between the decades of 1920 and 1930 in the cities of Natal, Recife, São Paulo, Porto Alegre and Rio de Janeiro; the autobiographical memoirs written by Café Filho himself and memoirs of other people who lived in his time. The main pillars that have supported the work were: the concepts of society and individuals (ELIAS, 1994; 1995), political cultures (BERSTEIN, 1998) and theater of the memory (GOMES, 2004); the sociability spaces category (CERTEAU, 1994; MALATIAN, 2001; RIOX, 1996); the biography notion (DOSSE, 2009; LORIGA, 2011). We demonstrated that Café Filho acted in some sociability spaces as: the Jornal do Norte, the Federação Regional do Trabalho and the Partido Democrático Nacional. In such spaces, Café Filho, gradually, become an important leader of workers and, at the same time, linked to national entities led to the opposition that fight against the power established in the Brazilian First Republic. In Café Filho’s interpretation, workers were individuals who needed to fight against the political structures prevailing at that time because the poor living conditions and the low representativeness of this group were caused by the way the political system in the First Republic was structured. After the 1930 Movement, the 3 de Outubro Club, the Jornal and the Labor Federation of Natal were constituted in spaces where the cafeista critical discourse about the government was changed: workers should follow the official syndicalism and defend the 1930 Movement which put Vargas in the presidency of the Republic.
