Resumo: O horizonte teórico do artigo passa pela defi nição e apropriação do campo conceitual que se arma ao redor das noções de "reescrita" e "paródia". Tais noções são aplicadas ao contexto literário português em sua especifi cidade pós-1974, ou seja, o contexto da literatura que se faz a partir da Revolução dos Cravos e da queda do regime de exceção até então predominante. Consequentemente, as noções referidas, aplicadas ao contexto histórico de emergência da diferença, se transformam e passam a confi gurar um cenário de intensa heterogeneidade entre produção fi ccional e trabalho de elaboração historiográfi ca. É nos interstícios dessa heterogeneidade que o presente artigo procura estabelecer seu ponto de vista de leitura dos textos.
reported results based on lJ4C palmitate label studies with trout which suggest that lipid absorption occurs in a manner quite different in fish from the usual routes in mammals.The paper of /. Blomberg reported on the composition of lipids in the melon of whale which suggests that lipids having different ultrasound transmission rates may be arranged to produce an acoustic lens to facilitate biosonar activity. In ensuing discussions, analogous research employing porpoises at other institutions in Canada and the United States were mentioned. Such current research is beginning to unravel the hitherto little understood chemical aspects of the mechanism of biosonar in marine mammals. The paper of G. Lambertsen discussed research on the relatively high unsaponifiables content of Arctic herring, capelin, and polar cod oils. The presence of fatty alcohols was revealed as probably coming from wax esters of similar composition which are a main constituent of the planktonic diet of these fish.W . T. Roubal reported on the use of the new spin-labeling technique in whi& a free radical-containing groupe.g., a nitroxideis attached to a lipid to serve as a tracer in such research as lipid oxidation and for investigating effects of environmental contaminants upon marine organisms. The unique advantages of such a technique were pointed out whereby not only the presence and amount of tracer is determined, but also information can be gleaned concerning interactions between exogenous, physiologically active materials and membranes and components of the membranes of cells.The final three speakers reported on investigations concerning commercial fish oils. G. Lunde, investigating the binding of phosphorous, selenium, bromine, and arsenic, related an increase in the first two proportional to the level of spoilage of the raw fish. Relative rates of decline in these bound elements during refining and hydrogenation were also discussed. The papers of N. Urdahl et al. and of P. C. Merk dealt with poisoning of the catalyst during the hydrogenation of fish oil containing sulphur and other catalyst poisons.The paper of the first group showed that the sulphur content increased as the degree of freshness of the fish, from which the oil was made, declined as a result of bacterial spoilage. The rate of hydrogenation decreased, or more catalyst had to be used to keep a constant rate, when the sulphur content increased.The final paper reported on an in depth kinetic study of the course of catalyst poisoning during different stages of hydrogenation. Results with different commercial catalysts and with both mackerel and capelin oil were presented, and the decrease in the catalyst activity during hydrogenation was discussed in terms of three kinetically distinguishable poisoning effects [see J. Amer. Oil Chemists' SOC. 49, 426 (1972)].
RESUMENEste trabajo muestra el estudio realizado para evaluar el comportamiento estructural de la cúpula de la Iglesia Jesuítica Santa Catalina, y su bóveda, así como las bóvedas del noviciado y de una habitación de la Estancia, con manifestación de fisuras.Se describen las tareas realizadas previas al análisis tensional, que incluyeron un relevamiento planialtimétrico general mediante estación total, a efectos de confeccionar los planos digitalizados y fundamentalmente, determinar los espesores de las bóvedas y cúpula. Se realizaron también dos pozos tangenciales para analizar las características del suelo y profundidad de las fundaciones. La verificación seccional se realizó con el software Algor, de análisis por elementos finitos, a partir de modelos sólidos de CAD.Los resultados de estos estudios, permitieron evaluar la seguridad de la estructura de bóvedas y cúpula, y proponer actuaciones para la preservación y mantenimiento de este edificio declarado patrimonio cultural de la humanidad por la Unesco.Palabras clave: cúpula; bóvedas; patrimonio; análisis tensional.ABSTRACTThis job shows the study realized to test the dome structural behavior, of Jesuit Santa Catalina´s church and his vault, also novitiate´s vault and one room from the ranch, with demonstrations of fissures.It describe a previously work at analysis tension, including a general 3D survey by a total station, in order to prepare the digital drawings and fundamentally determinate the thickness of the vaults and dome. Also realize two tangential wells to analyze the characteristics of the ground and the deepness of foundations. The sectional verification was made with Algor´s software analysis by very thin element from CAD solid models. The results of these studies allow assessing the safety vaults and dome structure, and propose actions for the preservation and maintenance of this building declared cultural heritage of humanity by UNESCO.Keywords: dome; vaults; heritage; stress analysis.
RESUMENLa Iglesia de Salsipuedes en la Provincia de Córdoba fue construida en el año 1875 y su techo está conformado por una estructura de madera, vigas reticulada y correas sobre las cuales se apoyan bovedillas cerámicas, capa de mortero y tejas musleras. La Iglesia está inhabilitada por precaución debido a la aparición de fisuras en barras del reticulado y desprendimiento de trozos de mampostería en las cercanías del apoyo de las vigas principales. En este trabajo se estudia el estado tensional de las barras del reticulado y la materialización del apoyo de las vigas principales en los muros de mampostería. Constatado el alto valor de las tensiones de trabajo de las barras con manifestaciones patológicas, como así también el inadecuado sistema de apoyo en la mampostería, se proyectan los refuerzos necesarios para lograr un funcionamiento de la estructura con un grado de seguridad adecuado. Palabras clave: estructuras; madera; patología; patrimonio. ABSTRACTSalsipuedes the Church of the Province of Cordoba was built in 1875 and its roof is formed by a wooden structure, reticulate beams and straps which support ceramic arches tile mortar layer and tiling Legguards The Church is disabled as a precaution due to the appearance of cracks in the grid bars and breaking away of pieces of masonry near the support of the main beams. In this work, we study the stress state of the grid bars and support the realization of the main beams in the masonry walls. Confirmed the high value of the working stresses of the bars with pathological manifestations, as well as inadequate support system in the masonry, projecting reinforcements necessary for safe operation of the structure with a degree of security.
