Patologias na formulação de um betão na ilha da Madeira

Existem diversos métodos de formular a composição de um betão, dos quais, este estudo realça a metodologia aplicada às curvas de referência, nomeadamente a de Faury. No âmbito desta dissertação, o estudo do betão foi focado nas propriedades da resistência à compressão e trabalhabilidade, e nos factores que as influenciam para a obtenção dos resultados pretendidos. A dificuldade deste estudo surgiu na obtenção da trabalhabilidade desejada, derivada do tipo de agregados existentes na empresa e incertezas na quantificação da água de amassadura. Esta foi analisada, com especial destaque, para os parâmetros de absorção e humidade, em que o ensaio normativo da obtenção da capacidade de absorção dos agregados, poderá não ser o mais indicado para quantificar o valor real deste parâmetro. Notou-se que o método de Faury para determinar a água de amassadura, não era o mais indicado, por não ter em conta os parâmetros anteriormente referidos. Foram realizados diversos ensaios de obtenção de parâmetros necessários para efectuar uma formulação acertada. Foram também realizadas diversas amassaduras, com composições distintas, de forma a analisar a sua influência nos resultados. Estes foram analisados através de critérios de conformidade, para classificação do betão em termos de resistência. Foi possível concluir que os resultados da formulação da composição do betão, dependem muito da qualidade dos agregados utilizados, como a sua forma, porosidade e homogeneidade do material pétreo. De acordo com os resultados experimentais, foi concluída a existência de uma insuficiência de finos nas composições criadas para o betão, sugerindo uma curva real granulometria de referência para potencializar a trabalhabilidade para o tipo de agregados utilizados neste estudo.

A estrutura burocrática de poder no stricto sensu em administração no Brasil: o caso do mestrado profissional em administração pública em Rede Nacional - PROFIAP

This study approaches bureaucratic organizational structures with the aim to understand the adherence procedure to virtual technologies in the stricto sensu educational administrative process. Thus, the author navigates through the formation of these organizations in Brazil with the intent to demonstrate the bureaucratic organizational culture and the consequent form of domination of those who detain power. In this epistemological construction, the author explores the culture s bureaucratic environment and the organizational power. In the analyses, it was observed the technological phenomenon in the ODL s administrative environment, which can explain the adherence procedure to structures and technological instruments for stricto sensu courses that, hypothetically, dilutes the traditional inherited organizational axiom. Therefore, it was utilized as object of study the Professional Master s degree in National Scale Public Administration PROFIAP, hence analyzing the documental content and the legislation related to institutionalization as well as the positioning of professors/coordinators and of the director of CAPES/MEC. Considering this axioms, it was concluded that the bureaucratic structures can admit ODL in the stricto sensu s environment. However, this can only be done as long as the adherence does not imply in a dilution of the traditional forms of power and institutional bureaucratic inherited dominance, as well as the alleged hegemony of the governmental structure in the educational administration adopted in person by the stricto sensu courses in Brazil

Estrutura de organizações sociais: adaptação aos projetos sociais ou às pressões institucionais?

This is a study concerning in the structure of non governmental organizations, based on the institutional theory. It aims to understand the relation among structure, social projects and environmental influences, analyzing if there is coherence with project social or expresses adaptation to the institutional pressures of the environment. It introduces as theoretical support for the themes, studies about institutional theory and social structure. The research is descriptive and exploratory; it also applies to a study of case, based on the technical procedures. From the research universe, that was compound by non governmental organizations from Natal, RN, Brasil, it was chosen the Casa Renascer, a non governmental organization that works with the combat to the violence and sexual exploration of children and teenagers. The data collection process employed includes documental research, observations and semi structured research devices, guided by the organizational process proposed by Serva (1996) and by the institutional theory. The collected data were qualitatively treated. The analysis was divided into three parts, following the research matters. The social project characterization demonstrated that the organization went by three main phases. The first one, characterized by focus in women and girls education and health; the second shows the emphasis on girls in social risk situation, with preventive approach; and the last one, characterized by victims assistance of violence and sexual exploration. From the analysis using the institutional theory mechanisms, the results showed that exists coherence between structure and environmental influences, but a weak coherence between structure and social projects. It indicates as main determinant of the structure, an aspect forgotten by the institutional theory, the power. It was observed the presence from normative, coercive and mimetic mechanisms, highlighting normative influences

GÊNERO E RELAÇÕES DE PODER NO PENTECOSTALISMO: ESTUDO COMPARATIVO ENTRE A IGREJA DE CRISTO NO BRASIL E A COMUNIDADE EVANGÉLICA SARA NOSSA TERRA

Based on the empirical comparative study between two churches from Pentecostal guidance - both located in Parnamirim/RN - and supported on a dialogic interaction between my interlocutors and theoretical references, I proposed me to reflect about how this protestant segment represents and articulates questions such as gender and power relationships, and the daily impact of that in their followers life. In other words, this dissertation aims to understand the reason of the asymmetry attributed to male and female, especially in what concerns the distribution of ecclesiastic works and the authority given to male, as well as the implication of this reality in the reconfiguration of morality and religious praxis in daily life of individuals and involved groups. From this perspective, this work was divided in three chapters, in which I investigate the tension/relationship between faith and secularism, for from this question on concessions and/or prohibitions related to the limits and involvement of the followers with the world and with the very Pentecostal ethos arise. I also analyze here aspects concerning to both ecclesiastic hierarchy and power, with the objective of elucidating how it occurs, what kind of criteria and implications they consider as well as about the nature of the religious labor division between men and women and, finally, I try to understand how the conversion/adhesion of members is reflected in the redefinitions of gender and its relationship between the ecclesiastical and domestic spaces. The diligence and energy spent in this work is in the hope that its fruits can corroborate in the expansion of anthropological knowledge which, in this particular case, involves the Brazilian Pentecostal phenomenon
