A conversão de D. José Brandão de Castro : a ação social de mediadores religiosos na Diocese de Propriá

This dissertation looked for to study the charisma of the religious mediator us " Movements of Christianity of Liberation " in the Diocese Sergipana of Propriá, during the decade from sixty to eighty. Centering our debate in the understanding of the social action, we have as main subject to understand the " poor " influence in the adoption of actions on the part of the mediators, in that public's favor, mainly in Fazenda Betume conflicts (1974) and of Santana dos Frades (1979). The hypotheses, we became pregnant that the mediators as D. José Brandão de Castro and the nun Maria Joana Hermínia exercised an important influence in the construction of the identity of the movements as CEBs, MEB and CPT in the area. Such influence was motivated by a conversion of the mediator D. Brandão, constituted starting from a relationship maintained between him and the members of the movements and proportionate for the critics and demands done by the popular ones. They resulted in actions in favor of the rural ones, what characterized the Church of Propriá as allied of the involved in the conflicts and no mere middleman. Before the collected material, we made use of the Analysis of Content using the poor " term " as analysis category, complemented by interviews done to members of the mentioned movements. Esta dissertação buscou estudar o carisma do mediador religioso nos “Movimentos de Cristianismo de Libertação” na Diocese Sergipana de Propriá, durante a década de sessenta a oitenta. Centrando nosso debate na compreensão da ação social, temos como questão principal entender a influência dos “pobres” na adoção de ações por parte do mediador, em favor desse público, principalmente nos conflitos da Fazenda Betume (1974) e de Santana dos Frades (1979). Como hipóteses, concebemos que os mediadores como D. José Brandão de Castro e a freira Maria Joana Hermínia exerceram uma importante influência na construção da identidade dos movimentos como as CEBs, o MEB e a CPT na região. Tal influência foi motivada por uma conversão do mediador D. Brandão, constituída a partir de uma relação mantida entre ele e os membros dos movimentos e proporcionada pelas críticas e demandas feita pelos populares. Elas resultaram em ações em favor dos campesinos, o que caracterizou a Igreja de Propriá como aliada dos envolvidos nos conflitos e não mera intermediária. Ante o material coletado, fizemos uso da Análise de Conteúdo utilizando o termo “pobre” como categoria de análise, complementada por entrevistas feitas à membros dos movimentos citados.

Influence of hydraulics and control of thermal storage in solar assisted heat pump combisystems

This paper studies the influence of hydraulics and control of thermal storage in systems combined with solar thermal and heat pump for the production of warm water and space heating in dwellings. A reference air source heat pump system with flat plate collectors connected to a combistore was defined and modeled together with the IEA SHC Task 44 / HPP Annex 38 (T44A38) “Solar and Heat Pump Systems” boundary conditions of Strasbourg climate and SFH45 building. Three and four pipe connections as well as use of internal and external heat exchangers for DHW preparation were investigated as well as sensor height for charging of the DHW zone in the store. The temperature in this zone was varied to ensure the same DHW comfort was achieved in all cases. The results show that the four pipe connection results in 9% improvement in SPF compared to three pipe and that the external heat exchanger for DHW preparation leads to a 2% improvement compared to the reference case. Additionally the sensor height for charging the DHW zone of the store should not be too low, otherwise system performance is adversely affected
