The Potiguar basin has large fields of viscous oil where the used method for recovering is based on vapor injection; this operation is carried out by injecting vapor in the oilwell directly, without the protection of a revetment through thermal insulation, what causes its dilation and, consequently, cracks in the cement placed on the annular, and lost of hydraulic insulation; this crack is occasioned by the phenomenon of retrogression of the compressive resistance due to the conversion of the hydrated calcium silicate in phases calcium-rich, caused by the high temperatures in the wells, subjected to thermal recuperation. This work has evaluated the application of composite pastes with addition of residue of biomass of ground sugar-cane bagasse as anti-retrogression mineral admixture for cementation of oil-wells subjected to thermal recuperation. The addition of the mineral residue was carried out considering a relative amount of 10, 20, 30, 40 and 59% in relation to cement mass, trying to improve the microstructure of the paste, still being developed a reference paste only with cement and a paste with addition of 40% of silica flour - renowned material in the oil industry as anti-retrogression additive. Pozzolanic activity of the ash was evaluated through XRD, TG/DTG, as the resistance to compression, and it was also determined the physical and mechanical behavior of the pastes when submitted to cure at low temperatures (22 and 38º C); besides it was evaluated the behavior of the pastes when submitted to two cycles of cure at high temperature (280ºC) and pressure (7 MPa). It was verified that the ash of the sugar-cane biomass presents pozzolanic reaction and has great efficiency in decrease the permeability of the paste by filler effect, as well as that addition of ash in a relative amount of 10, 20 e 30% increases cured compressive resistance at low temperatures. It was also showed that the ash in a relative amount of 40% and 59% has very significant efficiency as anti-retrogression additive, since it prevents the decrease of compressive resistance and forms hydrated calcium silicate type xenotlita and tobermorita which have more resistance and stability in high temperatures

Com o intuito de melhorar a eficiência na gestão e execução de responsabilidades junto dos munícipes, a Câmara Municipal de Angra do Heroísmo (CMAH), localizada na ilha Terceira (Região Autónoma dos Açores), distribui as suas valências por vários departamentos e colaboradores especializados. Apesar desta segmentação existem circunstâncias em que os mesmos trabalham em conjunto e cruzam informações, por exemplo, nos processos de licenciamento. Contudo, esta necessária troca de dados é deficiente quando se calendarizam eventos organizados ou não pela instituição em causa. Consequentemente, esta falha resulta muitas vezes na sobreposição de eventos, algo considerado insustentável numa comunidade relativamente pequena, como é o caso de Angra do Heroísmo (em 2013, contava com 35.109 habitantes). A autarquia pretende solucionar o problema tendo em conta as capacidades proporcionadas pelas plataformas da Web 2.0 que, entre outras, permitem a participação dos utilizadores e a fácil inserção e gestão da informação por pessoas sem conhecimentos técnicos aprofundados. Esta dissertação determina as especificações que devem estar presentes numa plataforma Web de calendarização e divulgação da oferta cultural, ao serviço do Município de Angra do Heroísmo; conceptualiza um protótipo funcional que valida as especificações identificadas e serve de apoio à construção da plataforma final a desenvolver no futuro. Esta investigação tem como fim melhorar o processo de calendarização e divulgação de eventos da oferta cultural do concelho angrense. Esta finalidade implicou a necessidade de conhecer aprofundadamente o funcionamento da instituição, identificando e distinguindo o papel dos vários intervenientes e processos, pelo que parte da investigação decorreu na Câmara Municipal de Angra do Heroísmo. Entre os vários desafios desta pesquisa destacam-se a recolha e compreensão de informação sobre o processo em estudo e o planeamento de um sistema digital intuitivo, que respeite as estruturas de decisão e o sistema hierárquico da autarquia e que detenha o grau de rigor exigido nas organizações governativas.

Em cada território, existe um universo considerável de aprendizagens disponível para a totalidade da população aí residente. Aos contextos formais e escolares, onde a hegemonia das culturas letradas importadas de latitudes económicas, sociais e culturais, tantas vezes distantes, e legitimadas pelos poderes nacionais, sempre se apresentaram, como alternativos ou complementares, os contextos não formais e informais, promovidos pelas instituições locais, geradas e desenvolvidas pela chamada sociedade civil. Nesta heterogénea realidade social e institucional, coexistem diversos conhecimentos, diferentes culturas e distintos estilos e processos de aprender. Nestes contextos, aparentemente enriquecidos pela diversidade, existe, mais ou menos evidente, uma fratura profunda. Uma fratura entre as culturas, as gerações e os rituais de aprendizagem. Uma falha social que, lenta, mas inexoravelmente, vai afastando os mais novos dos mais velhos, os mais ricos, dos mais pobres, os mais letrados dos menos letrados, os que ficam dos que saem.

OBJECTIVE: Study was to translate and culturally adapt the modified Rowe score for overhead athletes. METHODS: The translation and cultural adaptation process initially involved the stages of transla tion, synthesis, back-translation, and revision by the Translation Group. It was than created the pre-final version of the question naire, being the areas function and pain applied to 20 athletes that perform overhead movements and that suffered SLAP lesions in the dominant shoulder and the areas active compression test and anterior apprehension test and motion were applied to 15 health professionals. RESULTS: During the translation process there were made little modifications in the questionnaire in order to adapt it to Brazilian culture, without changing the semantics and the idiomatic concept originally described. CONCLUSIONS: The questionnaire was easily understood by the subjects of the study, being possible to obtain the Brazilian version of the modified Rowe score for over head athletes that underwent surgical treatment of the SLAP lesion.

This work indicates presuppositions for the qualitative research in Physical Education, starting with a literature review based on the cultural frame of reference. Firstly, we introduce the debate concerning the natural and the human sciences and implications for the Physical Education; we then use a cultural axis as a ground basis for the research in the area, proposing the 'dense description' as a possibility for knowledge building; finally, we bring up examples of studies conducted with such an approach. This theoretical methodological approach allows the study of the human being as a cultural being, thus opposed to the naturalised view of a human - predominant in Physical Education.
