Imitação e Retórica em Corte na Aldeia de Francisco Rodrigues Lobo

Corte na Aldeia (1619), de Francisco Rodrigues Lobo, é o primeiro manual de cortesania em língua portuguesa, inspirado por Il Cortegiano (1528), de Baldesar Castiglione, a obra-matriz do género. Em tempo de usurpação do trono português por Castela, é necessário “resgatar” a glória da antiga corte, que servirá de base à escrita de um manual destinado a formar o cortesão do futuro, o “discreto”, na sua expressão mais exigente. Este, investido da devida doutrina, poderá entretanto brilhar numa corte política e simbolicamente dispersa “pelas aldeias”. Ora, o domínio da eloquência e a adopção de uma retórica apropriada ao trato cortesão, assente numa língua portuguesa “renascida”, constituem as ferramentas essenciais de que importa munir o aspirante a cortesão, que, neste início do século XVII, poderá até ser originário da burguesia.

Infectious endocarditis caused by Nocardia sp.: histological morphology as a guide for the specific diagnosis

Nocardia is a rare opportunistic agent, which may affect immunocompromised individuals causing lung infections and exceptionally infective endocarditis (IE). There are few reports of IE caused by Nocardia sp., usually involving biological prostheses but rarely in natural valves. Its accurate microbiological identification may be hampered by the similarity with Rhodococcus equi and Corynebacterium spp. Here we report a case of native mitral valve IE caused by this agent in which the clinical absence of response to vancomycin and the suggestion of Nocardia sp. by histology pointed to the misdiagnosis of Corynebacterium spp. in blood cultures. The histological morphology can advise on the need for expansion of cultivation time and use of extra microbiological procedures that lead to the differential diagnosis with Corynebacterium spp. and other agents, which is essential to establish timely specific treatment, especially in immunocompromised patients.

Evaluation of Characterization and Performance Modeling of Cementitiously Stabilized Layers in the Mechanistic-Empirical Pavement Design Guide

Cementitious stabilization of aggregates and soils is an effective technique to increase the stiffness of base and subbase layers. Furthermore, cementitious bases can improve the fatigue behavior of asphalt surface layers and subgrade rutting over the short and long term. However, it can lead to additional distresses such as shrinkage and fatigue in the stabilized layers. Extensive research has tested these materials experimentally and characterized them; however, very little of this research attempts to correlate the mechanical properties of the stabilized layers with their performance. The Mechanistic Empirical Pavement Design Guide (MEPDG) provides a promising theoretical framework for the modeling of pavements containing cementitiously stabilized materials (CSMs). However, significant improvements are needed to bring the modeling of semirigid pavements in MEPDG to the same level as that of flexible and rigid pavements. Furthermore, the MEPDG does not model CSMs in a manner similar to those for hot-mix asphalt or portland cement concrete materials. As a result, performance gains from stabilized layers are difficult to assess using the MEPDG. The current characterization of CSMs was evaluated and issues with CSM modeling and characterization in the MEPDG were discussed. Addressing these issues will help designers quantify the benefits of stabilization for pavement service life.
