Sarcoidose cardiaque: a propos d'un cas.

in Revue Médicale de Liège (2008), 63(12), 707-9

Sarcoidosis is a systemic disease of unknown aetiology characterised by the formation of non caseating epithelioid cell granuloma, which can occur in virtually any organ. The involvement of the heart is ... [more ▼]

Sarcoidosis is a systemic disease of unknown aetiology characterised by the formation of non caseating epithelioid cell granuloma, which can occur in virtually any organ. The involvement of the heart is an important prognostic factor in sarcoidosis. Early treatment prevents irreversible damage of the heart and seems to be associated with better prognosis. [less ▲]

Bainite formation from intercritical austenite is of great practical importance for the production of TRIP-assisted steels. Silicon and aluminium play important roles during this transformation by delaying carbide precipitation, thus favouring the carbon enrichment of untransformed austenite, which makes its stabilisation down to room temperature possible. Previous studies have shown a strong dependence of bainite formation kinetics on both chemical composition and transformation temperature. In the present work, the effect of silicon and aluminium contents on bainite formation kinetics is investigated experimentally using dilatometry combined with microscopical observations. The experimental results are analysed by comparison with thermodynamic parameters, such as the activation energy G* for nucleation of bainite and the carbon content CT0 corresponding to the T0-curve. It is shown that the faster transformation kinetics induced by the substitution of silicon by aluminium can be ascribed (i) to a higher driving force for nucleation, (ii) to a higher carbon content CT0 at the T0-curve and (iii) to the precipitation of carbide in austenite in steels with a low Al content.

Perturbation finite element method for the analysis of earthing systems with vertical and horizontal rods

This paper deals with the electrokinetic modeling of earthing systems by means of a sub-domain perturbation finite element technique. An axisymmetric problem is solved for each single grounding rod or cable. Its solution must then be corrected by taking into account the influence of the other rods and cables. The electric scalar potential is transferred from one problem to the other through projections between meshes. An inherently 3D problem can thus be solved as a succession of 2D sub-problems, which significantly speeds up the solution and enables to tackle complicated grounding systems. [less ▲]
