La présente thèse analyse les facteurs expliquant l'attrait académique pour la Near-Death Experience (NDE) aux Etats-Unis. À travers l'étude d'un acteur clé, Russell Noyés, la thèse démontre que l'expérience de mort imminente est devenue pertinente grâce aux psychiatres et aux psychologues qui lui ont octroyé une qualité clinique et thérapeutique. Afin de reconstruire les fondements académiques de l'intérêt pour l'étude de la mort, de l'expérience de la mort et de la mort imminente en psychiatrie dans les années 1960-70, la méthode employée est celle d'une enquête historique qui combine une approche empirique avec une génétique de récit. - The dissertation analyses the factors explaining the emergence of the Near- Death Experience (NDE) as a research topic in the disciplines of psychology and psychiatry in the United States. The study of a key actor, Russell Noyes, will demonstrate how the experience of near-death became relevant through the work of psychiatrists and psychologists who attributed a clinical and therapeutical quality to it. In order to retrace the academic foundations of the research on death, the experience of dying and near-death, during the 60s and 70s, this dissertation applies a historical method, which combines an empirical approach with a genetic of narratives.

The research project, HR-110, was begun in the fall of 1964 to further investigate the compositional and mechanical properties of some of the carbonate rocks used as aggregate in portland cement concrete. Samples were taken only from those portions of the quarries that are used as aggregate in portland cement concrete by the Iowa State Highway Commission except where designated by commission personnel for purposes of evaluation of potential aggregate sources. Where practical, the samples were taken from each bed recognized by the Highway Commission geologists, and in most instances, the thicker beds were sampled at the top, middle, and bottom to detect any lithologic changes that escaped megascopic observation.

This investigation was conducted to study the performance characteristics of low cost roadway surfaces of soil-aggregate-sodium chloride mixtures. Many roads have been successfully stabilized with sodium chloride. However, little information is available on either the properties of the road materials or the effects of sodium chloride on the materials. The performance of some of the sodium chloride stabilized roads in Franklin County, Iowa, and the performance of some near-by nonchemically treated roads has been studied. The study of sodium chloride stabilized roads was restricted to the roads in which the binder soil used in construction came from the same source. The effects of sodium chloride on some of the engineering properties of the soil and soil-aggregate mixtures used were studied in the laboratory.

Heavy traffic volumes frequently cause distress in asphalt pavements which were designed under accepted design methods and criteria. The distress appears in the form of rutting in the wheel tracks and rippling or shoving in areas where traffic accelerates or decelerates. Apparently accepted stability test methods alone do not always assure the desired service performance of asphaltic pavements under heavy traffic. The Bituminous Research Laboratory, Engineering Research Institute of Iowa State University undertook the development of a laboratory device by which the resistance of an asphalt paving mix to displacement under traffic might be evaluated, and also be used as a supplemental test to determine adequacy of design of the mix by stability procedures.

A study was undertaken by the Bituminous Research Laboratory of the Engineering Research Institute at Iowa State University, under the sponsorship of the Iowa Highway Research Board, project HR 100, to ascertain the effects of a number of characteristics and properties of asphaltic concrete mixes upon the service behavior of the mixes as evaluated by the Traffic Simulator and by field observations. The study included: Investigations of the relations, of gradation, fraction and resistance to wear of aggregates; of stability, cohesion, per cent voids and asphalt content: of a number of laboratory and field mixes to service behavior as indicated by the Traffic Simulator under various test conditions. Based upon the results of the tests and the relationships noted, tentative criteria for the Traffic Simulator test were devised, subject to verification by observations and measurements of field service behavior of the mixes.

During the summer of 1963 the Materials Department noted the three to four ·year old concrete pavement on I-80 in Cass County was showing extensive surface cracking adjacent to joints and cracks. An examination of the pavement and a few cores from the cracked areas was made by the I.S.H.C. Materials Department and later by David Stark of the P.C.A. Additional surveys were conducted on other concrete pavement made with coarse aggregate from similar rock from two different sources. Blue-line cracking was found on some primary pavement and the indications of incipient cracks were seen on I-29 in Pottawattamie County, north of Council Bluffs. A good "D"-crack pattern is now evident. Surveys were then made of the entire Interstate concrete pavement. No other sections of Interstate were "D"-cracking, although some sections showed joint discoloration. None of these pavements, including the discolored sections, contained "D"-crack associated aggregates. At the same time as the Interstate survey additional pavements and sources were checked. Some "D"-cracking was noticed on certain sections of primary pavement 5-10 years old, in the vicinity of Waterloo and Cedar Rapids. The "D"-cracked pavement was from three aggregate sources, the Newton, Otis, and Burton Ave. quarries. Other pavements in this area that were older or from· different· coarse aggregate sources were not "D"-cracked. We believe that all the "D"-cracking is related, although dedolomitization is probably involved in the intermediate dolomite rocks.

A admiración que destilou no seu tempo e durante o século XIX o bo sentido común das obras de Benjamin Franklin (1706-1790) plasmouse na tradución dos seus libros a un considerable número de linguas. The Way to Wealth (El camino de la fortuna o Cómo hacerse rico), publicado en 1758, contén máis de cen máximas que instan ao traballo honrado, á orde e ao aforro, condenando calquera sinal de preguiza ou desidia. O noso corpus nútrese dunha selección de trece aforismos que teñen relación precisamente con este vicio que condena á miseria, a preguiza. En cambio, o home de ben que aplique as virtudes contidas en The Way to Wealth, aconselladas a modo de refráns, verá, segundo o autor, prosperar esplendidamente a súa economía. Pretendemos analizar, dende os puntos de vista tradutolóxico e contrastivo, o corpus de dúas traducións españolas deste libriño de Franklin: unha anónima, publicada en Barcelona, en 1891; e a de Alberto Lena de 1999.
