We employ numerical models of Mars at spatial scales ranging from global to a few metres in order to investigate both the impact of increasing dust loading on atmospheric circulations and the role of different atmospheric circulation components on dust lifting, transport and on dust storm decay. Figure 1: Typical dust lifting events, relevant spatial scales and meteorological models suitable fo...

The paper presents the solution of a three-dimensional (3-D) magnetostatic problem using the finite formulation of an electromagnetic field. Two different approaches, based on a primal-dual barycentric discretization of the 3-D space, are presented, considering as unknowns either the magnetic fluxes or the circulations of the vector potential. Results on simple reference configurations are repo...

Abstract This article addresses the relation between Andean ‘traditional music’ and circulations of people, objects, ideas sounds. Although many studies on indigenous music have explored such circulations, scholars still tend to understand musical practices in terms ‘cultures’. The case from Otavalo, Ecuadorian Andes, encourages us go beyond this approach. I make two arguments. First, by concei...
