Singular lagrangians: some geometric structures along the Legendre map [PDF]
New geometric structures that relate the lagrangian and hamiltonian formalisms defined upon a singular lagrangian are presented. Several vector fields are constructed in velocity space that give new and precise answers to several topics like the projectability of a vector field to a hamiltonian vector field, the computation of the kernel of the ...

Abstract Let be a domain, or more generally, a Lipschitz domain with small local Lipschitz constant. In this paper it is shown that if u is a function harmonic in and continuous in , which vanishes in a relatively open subset ; moreover, the normal derivative vanishes in a subset of with positive surface measure; then u is identically zero.

The historical roots of the creation of the Catalan private-public hospital model: c. 1870-1935
This paper analyses the roots of the creation of the Catalan hospital model, based on a preponderance of privately owned hospitals and beds over those of public provision.

Abstract Social innovations are grassroots processes aiming to achieve impacts beyond an individual level and towards a broader societal good. The environmental dimension of impacts refers to any direct change to the environment resulting from social innovation activities, products, or services, which are not addressed by pre‐existing systems.

This article examines the territorial configuration of Spain between 1978 and 1983. The article investigates whether the scope of autonomy granted to the regions inhabited by “the historical nationalities” fulfilled their need of being independent from ...

Introduction. A mixed model of hospital services: Catalonia, 1870s-2010s
This special issue aims to contribute to current knowledge held on mixed hospital systems from a historical perspective, as there is nowadays much debate on the sustainability and efficiency of public and private healthcare systems in the world in the ...

Assessing light pollution in vast areas: zenith sky brightness maps of Catalonia [PDF]
Zenith sky brightness maps in the V and B bands of the region of Catalonia are presented in this paper. For creating them we have used the light pollution numerical model Illumina v2. The maps have a sampling of 5x5 km for the whole region with an improved resolution of 1x1 km for one of the provinces within Catalonia, Tarragona.
