O problema da taxatividade do rol do art. 1.015 do Novo Código de Processo Civil

A presente monografia tem como objetivo estudar a problemática surgida a partir da previsão constante do Novo Código de Processo Civil, a qual concebe um rol taxativo de hipóteses de cabimento do recurso de agravo de instrumento. Necessária será a diferenciação entre a antiga sistemática do r. recurso em relação à atual, posto que divergem em pontos nodais. No curso da análise, priorizar-se-á, ainda, trazer à tona o que a atual previsão implicou de problemas práticos para quem opera cotidianamente o direito em suas diversas variantes. Ademais, estabelecidos os pontos entendidos como controversos – utilizando para tal a mais respeitada doutrina e o entendimento dos tribunais pátrios acerca do tema –, buscar-se-á delinear soluções cabíveis para saná-los, seja via outras exegeses interpretativas, seja via cabimento de mandado de segurança

Effects of heat treatments on the microstructure and mechanical properties of a 6061 aluminium alloy

International audienceThis paper describes the mechanical behavior of the 6061-T6 aluminium alloy at room temperature for various previous thermal histories representative of an electron beam welding. A fast-heating device has been designed to control and apply thermal loadings on tensile specimens. Tensile tests show that the yield stress at ambient temperature decreases if the maximum temperature reached increases or if the heating rate decreases. This variation of the mechanical properties is the result of microstructural changes which have been observed by Transmission Electron Microscopy

Comparative study of the microstructure between a laser beam melted 17-4PH stainless steel and its conventional counterpart

The aim of this work was to compare the microstructures of 17-4PH martensitic stainless steels (MSSs) obtained by conventional manufacturing (CM), and additive manufacturing (AM) using laser beam melting (LBM) process. Both materials were studied after the same H900 heat treatment. Significant differences in microstructure were observed between the two MSSs, with a higher austenite content for the AM-H900 sample, as compared to the CM-H900 sample. Transmission electron microscopy (TEM) analyses allowed to identify both retained and reversed austenite in the AM-H900 sample, but most part of the austenite detected was found to be reversed austenite. The high amount of reversed austenite in the AM-H900 sample was attributed to a heterogeneous distribution in austenite-stabilising elements in the solution heat treated AM sample, leading to a decrease in Ms value and subsequent increase in the driving force for the martensite to austenite transformation during the ageing at 480 °C. Moreover, TEM analyses highlighted thinner martensite laths for the AM-H900 steel as compared to the CM-H900 one. This was interpreted as an increase in both nucleation sites and growth rate for reversed austenite. Despite those differences in microstructure, the AM-H900 and CM-H900 samples showed similar tensile behaviour, with similar UTS and Rp0.2 values, but a decrease in the strain to fracture was observed for the AM-H900 sample, probably related to the pores and/or to intergranular carbides

Behavioral and biological risks of women seeking HIV test in an anonymous testing center

Due to the high prevalence and morbidity sexually transmitted diseases are highly relevant to public health, especially for women. OBJECTIVES: To determine and compare the behavioral and biological risks associated with human immunodeficiency virus acquisition. METHODS: A group of 253 women who voluntarily sought anonymous testing were interviewed to find out their behavioral risk. Biological risk was identified by means of gynecological exam, colposcopy as well as blood and cervicovaginal sampling for serological and microbiological exams. Using known traditional risk factors, a table of scores classified the subjects into high, low and absent for behavioral and biological risks. Frequency and percentage of each risk was tabulated and the correlation between risks was obtained by calculating the Kappa statistic. RESULTS: 79.8% of subjects were found to have behavioral risks, and 79.1% biological risks. It was also found that 66.7% of the women (169) with high behavioral risk also had high biological vulnerability. However, 31 out of 51 women without any behavioral risk had biological vulnerability 12.2 %. The Kappa statistic demonstrated low agreement between the latter risks [K = 0.05 95% CI (-0.06 to 0.17)]. CONCLUSION: Women who seek care in centers for anonymous testing have high biological risk, which is neither proportional nor concurrent to behavioral risk. The low concordance found between these risks suggests the need for routine gynecological investigation (clinical and microbiological) for all women.36036

Influences mécaniques et métallurgiques de procédés haute température sur un alliage d\u27aluminium 6061-T6

Le travail de thèse présenté dans ce mémoire s\u27inscrit dans le cadre des actions de qualification anticipée du caisson du RJH (Réacteur Jules Horowitz). Le caisson est une enceinte sous pression fabriquée en alliage d\u27aluminium 6061-T6. Il s\u27agit d\u27un alliage à durcissement structural dont les propriétés mécaniques sont étroitement liées à l\u27état de précipitation dans le matériau. Des essais de traction ont permis de mesurer l\u27évolution des propriétés mécaniques du matériau ayant subi des chargements thermiques représentatifs d\u27une opération de soudage par faisceaux d\u27électrons (soudage FE). Des essais ont été menés à température ambiante et à chaud. Des observations métallurgiques par Diffusion de Neutrons au Petits Angles (DNPA) et par Microscopie Electronique en Transmission (MET) donnent par la suite la taille et la fraction volumique des précipités. Les résultats de ces campagnes d\u27essais permettent de comprendre l\u27évolution des propriétés mécaniques. Ces expérimentations ont ensuite été utilisées pour mettre en place un modèle métallurgique permettant de calculer les caractéristiques de l\u27état de précipitation. Ce modèle étant couplé à un modèle de durcissement structural, il calcule la limite d\u27élasticité du matériau pour divers chargements thermiques. Un modèle mécanique phénoménologique a également été développé afin de modéliser le comportement d\u27une structure soumise à un chargement thermique

This vessel is made of aluminium alloy 6061-T6. this is an age hardening allow whose mechanical properties are closely related to the precipitation state in the material. Tensile tests were used to measure the evolution of the mechanical properties of the material previously subjected to thermal loading representative of an electron beam welding operation (EB welding). Tests were conducted at room temperature and at high temperature. Then metallurgical observations by small Angle Neutron Scattering (SANS) and by Transmission Electron Microscopy (TEM) gave the size and the volume fraction of precipitates. The results of these campaigns improved our understanding of the mechanical properties and evolution with thermal history. Furthermore, these experiments were used to develop a metallurgical model to forecast the characteristics of the precipitation state. A model was linked to a hardening model for the calculation of the yield strength of the material after various thermal loading. A phenomenological mechanical model was also developed to represent the behaviour of a structure subjected to thermal loading.VILLEURBANNE-DOC'INSA LYON (692662301) / SudocSudocFranceF
