At long-term BVS follow-up, we observed a favorable tissue response, with late luminal enlargement, side-branch patency, and development of a signal-rich, low-attenuating tissue layer that covered thrombogenic plaque components. The small size of the study and the observation of a different tissue response in 1 patient warrant judicious interpretation of our results and confirmation in larger studies.

As organizações confrontam uma série de dificuldades na condução de iniciativas de melhoria de processos de software (SPI). As causas podem estar relacionadas a aspectos de cunho organizacional, tecnológico e sociocultural. Alguns desses aspectos são considerados fatores críticos de sucesso. Neste contexto, este trabalho apresenta um catálogo de práticas que podem ser utilizadas para tratar os fatores críticos negativos. Este catálogo foi concebido a partir de ciclos de aprendizado incrementais, utilizando a metodologia Design Science Research. Em uma avaliação do catálogo realizada por meio de dois estudos de caso, foi identificada a pertinência de 84% das práticas em relação aos contextos das iniciativas de MPS em questão.

The stainless steel employed in the structural elements present high corrosion resistance, durability, fire resistance and high aesthetic value compared to those constructed using carbon steel. In contrast, the stainless steel structures design is made following the requirements based on the carbon steel analogies. In fact, the structural performance of stainless steel is complex and dissimilar where some stainless grades presenting nonlinear tension versus strain curves without a defined yield plateau and large strain hardening. These properties influence on structural performance of the lap bolted joints. The Eurocode 3 pt. 1.4, one of the most adopted design codes, recommends two structural design criteria for the stainless steel elements under tension: ultimate resistance of the net cross-section at holes or plastic resistance of the gross crosssection. The present work aimed to investigate the structural response of lap bolted joints made of three stainless steel grades: austenitic, ferritic and duplex. Nonlinear numerical analyses has been carried out using ABAQUS 6.14 program where the response have shown a good agreement in terms of the maximum loads and failure modes when compared to the performed experiments. The results indicated a conservative level of safety from Eurocode 3 pt. 1.4 code provisions in comparison to the experimental results.
