Glycosaminoglycans in human retinoblastoma cells: heparan sulfate, a modulator of the pigment epithelium-derived factor-receptor interactions
(BioMed Central, 2003-02-19)
BACKGROUND: Pigment epithelium-derived factor (PEDF) has binding affinity for cell-surface receptors in retinoblastoma cells and for glycosaminoglycans. We investigated the effects of glycosaminoglycans on PEDF-receptor ...
Constant mean curvature hypersurfaces with constant δ-invariant
(Hindawi Publishing Corporation, 2003)
We completely classify constant mean curvature hypersurfaces (CMC) with constant
δ-invariant in the unit 4-sphere S4 and in the Euclidean 4-space E4.
An Analysis of English, Spanish and Basque Demonstratives in Narrative: a Matter of Viewpoint
(Universidad de Murcia, Servicio de Publicaciones, 2003)
[EN]This paper undertakes the study of the occurrence of non-corresponding demonstrative forms in Spanish, Basque and English in exactly the same linguistic context. It is proposed that the differenccs in the choice of the ...
Hospitalization for respiratory syncytial virus in the paediatric population in Spain
(Cambridge University Press, 2003-10)
The aim of this population-based retrospective study was to determine the incidence of hospitalization for community-acquired, laboratory-confirmed respiratory syncytial virus (RSV) infection in an unselected paediatric ...
Fishing effort validation and substitution possibilities among components: the case study of the VIII division European anchovy fishery
(Routledge. Taylor & Francis, 2003)
Command and control regulation programs, particularly input constraints, typically
fail to achieve stated objectives, because fishermen may substitute unregulated for
regulated inputs. It is, thus, essential to have an ...
Cohomologically Kähler manifolds with no Kähler metrics
(Hindawi Publishing Corporation, 2003)
We show some examples of compact symplectic solvmanifolds, of
dimension greater than four, which are cohomologically
Kähler and do not admit Kähler metric since their
fundamental groups cannot be the fundamental group ...
Role of occupied d bands in the dynamics of excited electrons and holes in Ag
(American Physical Society, 2003)
The role that occupied d bands play in the inelastic lifetime of bulk and surface states in Ag is investigated from the knowledge of the quasiparticle self-energy. In the case of bulk electrons, sp bands are taken to be ...
Spanish Customer Satisfaction Indices by Cumulative Panel Data
(2003-07)
In this paper, we present a new theoretical representation of the Consumer Satisfaction Index (CSI) based on Structural Equation Modelling (SEM). We use panel data collected by an automotive magazine to apply our approach ...
