Within the growing literature on the Europeanisation of national foreign policies of European Union (EU) member states, the case of Portugal has been almost absent. Yet despite its small size and intermediate level of development, Portugal has had relatively extensive international relations...

La cuestión ambiental, la sustentabilidad, una producción de alimentos más sanos son temas que cuentan con una universalidad conceptual, pero también dependen de disputas locales alcanzando así una universalidad social construida. Entender las posiciones sociales de los diferentes actores...

We present a new second-order (in space), semi-discrete, central scheme for the approximation of hyperbolic conservation laws in three space dimensions. The proposed scheme is applied to a model for two-phase, immiscible and incompressible displacement in heterogeneous porous media. Numerical...

We use a nonoverlapping iterative domain decomposition procedure based on the Robin interface condition to develop a new multiscale mixed method to compute the velocity field in heterogeneous porous media. Hybridized mixed finite elements are used for the spatial discretization of the equations....

One of the most difficult tasks in subsurface flow simulations is the reliable characterization of properties of the subsurface. A typical situation employs dynamic data integration such as sparse (in space and time) measurements to be matched with simulated responses associated with a set of...

We describe a fractional-step numerical procedure for the simulation of immiscible three-phase flow in heterogeneous porous media that takes into account capillary pressure and apply it to indicate the existence of a so-called “transitional” wave in at least some multi-dimensional flows,...
