Memória ferroviária : da mobilização social à política pública de patrimônio

Esta tese tem como objetivo o estudo do processo de construção e apropriação do passado ferroviário e da transformação da memória ferroviária como objeto de política pública, sobretudo após a edição da Lei no 11.483/2007. O estudo aborda os papeis desempenhados por agentes sociais diversos, como as associações de preservação ferroviárias (APF), a Rede Ferroviária Federal (RFFSA) e o Instituto do Patrimônio Histórico e Artístico Nacional (Iphan), e suas estratégias de ressignificação e objetificação do passado ferroviário, processo que teve início ainda na década de 1970. A pesquisa descreve a implantação da malha ferroviária brasileira, de maneira a contextualizar a extinção da RFFSA, em 2007; aborda o surgimento e evolução das APFs, e descreve a atuação da Rede na preservação e salvaguarda do passado da ferrovia por meio da análise do Programa de Preservação do Patrimônio Histórico Ferroviário (Preserfe). Por fim, a tese se debruça sobre a atuação do Iphan, recorrendo à análise dos processos de tombamentos de bens ferroviários e ao estudo dos desdobramentos da Lei no 11.483/2007 no interior do órgão. O movimento de valorização do passado ferroviário contribui para os debates acerca dos processos de apropriação e patrimonialização do passado.

Fazer a ponte para a escola de todos(as)

The purpose of this study is to understand what are the matrix elements in which everyday activities of social author/authors, actor/actors and actress/actresses are embedded, in order to carry out the Escola da Ponte s political and pedagogic process (PPP). Thus, the object of this study is to reflect on an experience developed in a public school supported by the Portuguese State within the scenario of institutions that are committed to building up a school of the people by investing in democratization and community participation in their management process. The methodological course of action was targeted at the presuppositions of qualitative research (WOODS, 1999; BURGESS, 1997; MILLS, 1982; OLIVEIRA, 1998; BOGDAN and BIKLEN, 1994; MACEDO, 2000; CASAL, 1996; GEERTZ, 2000), with data collected from random word association (MACHADO and CARVALHO, 2003), the discourse of the interviewed (KAUFMANN, 1996; SILVA, 2006; 2002), observation notes and documents (ELIAS, 1997). Based on a multiple reference and theoretical framework, the investigation revealed elements that are construed as the raw material and pillars supporting the bridge of a school of the people, as well as the self-organization of the school community which emerges as a dimension that binds together all the elements and brings new arrangements into the school dynamics by moving from the individual to the society (DUPUY, 1990). Along this line, the central argument is that in the short and long run the public school quality does not spring from macro educational policies, nor from ephemeral mass-production programs, projects or governmental policies, but from the intent of the professionals working there in becoming authors and characters in the process of building up and carrying out the PPP. The Project has been conceived in the light of the needs and intentionality of the community whose support comes from the participation and social control held by the students families and the community s power to force to action public administration central agencies aiming at having the State fulfill its responsibilities

A construção da ponte metálica sobre o Rio Pontengi: aspectos históricos, construtivos e de durabilidade - Natal/RN, Brasil (1912-1916) - estudo de caso

It is a case study that reports the construction of metal truss bridge in the river Potengi in Natal, Rio Grande do Norte, between the years 1912 and 1916. From testimonials on steel bridges in Brazil and worldwide including foundations. Documentary research from procurement of projects and contracts was performed. A chronology of construction, with a description of the equipment used and its original budget with the Brazilian government. Still, we used interviews and surveys with experimental sampling / testimonies, laboratory tests. This study aims to analyze historically and technically the Bridge over the River Potengi, emphasizing primarily the construction process, the qualities and characteristics of the materials used and the technological, chemical, mineralogical and microstructural properties of cement and concrete used in its construction. Taking as conclusions that cements pozolônicos ensured a good durability to the concrete in a hundred-year period and that the solution employed with the compressed air caissons was right

Modelo de ashkin-teller de três cores na rede ponte de wheatstone

In this work we study the phase transitions of the ferromagnetic three-color Ashkin-Teller Model in the hierarquical lattice generated by the Wheatstone bridge using real space renormalization group approach. With such technique we obtain the phase diagram and its critical points with respective critical exponents v. This model presents four phases: ferromagnetic, paramagnetic and two intermediates. Nine critical points were found, three of which are of Ising model type, three are of four states Potts model type, one is of eight states Potts model type and the last two which do not correspond to any Potts model with integer number of states. iv

Trombectomia na angioplastia primária em ponte de safena

O emprego da trombectomia na angioplastia primária demonstra bons resultados clínicos e angiográficos imediatos, por meio de redução da embolização distal e do fenômeno do no-reflow e otimização da perfusão miocárdica. Essa técnica, principalmente usada em artérias coronárias, em raras oportunidades é descrita quando empregada em pontes de safena aortocoronarianas. Relatamos o caso de um paciente de 67 anos com infarto agudo do miocárdio relacionado a oclusão de ponte de safena e submetido a trombectomia com bons resultados.

Os marcos da paisagem da cidade no contexto da trama urbana de Natal/RN: um estudo a partir do Morro do Careca, o Midway Mall, o Pórtico dos Reis Magos e a Ponte Newton Navarro

The present work is a study on the functions performed by landmarks landscape Natal / RN in the urban fabric, in the case of Midway Mall, the Portico dos Reis Magos, the Morro do Careca and Newton Navarro Bridge. For such goals established itself as analyze the functionality of the milestones presented here in the urban fabric; discuss the importance of these landmarks of the city landscape in the process of urbanization of Natal, and identify and spatialize actions related to the use of territories where are located landmarks, discussing their reflections. To achieve these goals we chose to use as a literature search procedures, the problematic concept, working with oral sources, and reading speechless. To support this research the main concepts were worked landscape, city, landmark, public space, circuits, among others. After going over the theory, consistent with the empirical data, it appears that the landmarks studied here have different functions and features, but all carry different forms of fascination for the public and visitors to the city, and every man your way, influence the public space, land speculation and feature importance in the process of urbanization of Natal
