BACKGROUND Pigmented villonodular synovitis (PVNS) is characterized by the presence of inflammation and hemosiderin deposition in the synovium. Two forms of PVNS distinguished in the literature are diffused and localized involvements. There are controversies in the literature about the surgical management of PVNS. We report our experience in the management of knee PVNS at a mean follow-up of 4 ...

In the last century, economic growth has been accompanied by a worldwide diffusion of polymers for multiple applications. However, there is growing attention to environmental pollution and energy consumption linked unconditional use plastic. present work, exergy used as measure resource during life cycle polymers. Nine commercially diffused are chosen, their production chains identified accordi...

A level set method combining features of front tracking methods and fixed domain methods is presented to model microstructure evolution in the solidification of multi-component multiphase alloy systems. Phase boundaries are explicitly tracked by solving the multi-phase level set equations. Diffused interfaces are constructed by extending a small width in both directions from these explicitly tr...

The seven-equation model is a compressible multiphase formulation that allows for phasic velocity and pressure disequilibrium. These equations are solved using diffused interface method models resolved flows. Novel extensions proposed including the effects of surface tension, viscosity, multi-species, reactions. allowed non-equilibrium in provides numerical stability strong shocks arbitrary ind...

Meteorological and climatic phenomena affect oceanographic characteristics and, consequently, anthropogenic microparticle aggregation. The same influence the ecology of pelagic fish, but whether there is a connection between meteorological ingestion remains unknown. In NW Mediterranean during springs 2011–2014, incidence contaminated European anchovies (35 ± 17%) abundance in stomach content (0...
