New Uses for Old Needs in the Diaspora: Watching Basque Television in Latin America
(Macquarie University, 2006)
The transformations occurring in the communications media are resulting in the emergence of new uses amongst diasporic and migratory groups. An example of this is found in satellite television, which makes the regular, ...
Exchange-Correlation Hole of a Generalized Gradient Approximation for Solids and Surfaces
(American Physical Society, 2009-02)
We propose a generalized gradient approximation (GGA) for the angle- and system-averaged exchange-correlation hole of a many-electron system. This hole, which satisfies known exact constraints, recovers the Perdew-Burke-Ernzerhof ...
La autoridad en María de Ajofrín y Teresa de Cartagena, ¿un desafío?
(Universidad de Granada, 2004-07)
[ES] Este artículo analiza los recursos utilizados por María de Ajofrín y Teresa de Cartagena para crear un paradigma femenino de autoridad creadora. Aunque parten de circunstancias similares, sus soluciones difieren. ...
On minimal realizations and minimal partial realizations of linear time-invariant systems subject to point incommensurate delays
(Hindawi Publishing Corporation, 2008)
This paper investigates key aspects of realization and partial realization theories for linear time-invariant systems being subject to a set of incommensurate internal and external point delays. The results are obtained ...
On pole-placement controllers for linear time-delay systems with commensurate point delays
(Hindawi Publishing Corporation, 2005)
We investigate the exact and approximate spectrum assignment properties associated with realizable output-feedback pole-placement-type controllers for single-input single-output linear time-invariant time-delay systems ...
Scientific theories as intervening representations
In this paper some classical representational ideas of Hertz and Duhem are used to show how the di-chotomy between representation and intervention can be overcome. More precisely, scientific theories are reconstructed as ...
Oscillatory behavior in linear difference equations under unmodeled dynamics and parametrical errors
(Hindawi Publishing Corporation, 2007)
This paper investigates the presence of oscillating solutions in time-varying difference equations even in the case when there exist parametrical errors (i.e., errors in the sequences defining their coefficients) and/or ...
Hospitalization rates for human metapneumovirus infection among 0- to 3-year-olds in Gipuzkoa (Basque Country), Spain
(Cambridge University Press, 2009-01)
Numerous studies have been published on human metapneumovirus (HMPV) infection, but few have been population based. The main aim of this study was to estimate the incidence rate of hospitalization for community-acquired ...
La discusión conceptual sobre el milenarismo y mesianismo en Latinoamérica
(Universidad de Navarra, 2001)
Effects of the whole seed and a protein isolate of faba bean (Vicia faba) on the cholesterol metabolism of hypercholesterolaemic rats
(Cambridge University Press, 2001-05)
The aim of the present work was to analyse the hypocholesterolaemic efficiency of a Vicia faba-protein isolate in relation to the intact legume. In addition, the mechanisms underlying the effects of this isolate were ...
