Efecto de la zona de contacto entre fibra y matriz en las propiedades de fractura de materiales compuestos sometidos a carga transversal
(Grupo Español de Fractura, 1997)
El presente trabajo trata de dilucidar si en presencia de despegues entre fibra y matriz, se produce contacto circunferencial entre ambas fases cuando el conjunto está sometido a carga transversal a la fibra. Se utiliza ...

Site-directed Mutagenesis of Cytochromec 6 from Synechocystissp. PCC 6803
(Elsevier, 1999)
This paper reports the first site-directed mutagenesis analysis of any cytochrome c 6, a heme protein that performs the same function as the copper-protein plastocyanin in the electron transport chain of photosynthetic ...

Three-dimensional modelling of the tidal dispersion of non-conservative radionuclides in the marine environment. Application to 239,240 Pu dispersion in the eastern Irish Sea
(Elsevier, 1999)
A three-dimensional model to simulate the tidal dispersion of non-conservative radionuclides in a marine environment has been developed. The model solves the three-dimensional hydrodynamic equations using normalized s ...

Reliable analysis of settling errors in SC integrators - application to high-speed low-power ΣΔ modulators design
(1999)
This paper presents a detailed study on the transient response of SC integrators taking into account the effects of amplifier finite gain-bandwidth product and slew-rate during, unlike previous models, both the integration ...

Modelling the dispersion of non-conservative radionuclides in tidal waters .2. Application to Ra-226 dispersion in an estuarine system
(Elsevier, 1996)
The Odiel river is an estuary system located in the south-west of Spain and affected by tidal dynamics. A phosphate fertilizer processing plant releases part of its wastes directly into the Odiel river. The model described ...

210Pb distribution in riverwaters and sediments near phosphate fertilizer factories
(Elsevier, 1996)
two fertilizer factories operate at the estuary formed by the Odiel and Tinto rivers in Southwestern Spain. In previous work the authors have shown that such operation enhances the natural radionuclide background of the ...

Radioactive impact of phosphate ore processing in a wet marshland in southwestern Spain
(Elsevier, 1997)
In this paper an extensive study of the presence of natural radionuclides in a marshland area located in the vicinity of a phosphoric acid production complex in southwestern Spain is presented. This marsh is a natural ...

The limit relations between generalized orthogonal polynomials
(Elsevier, 1997-09)
We consider the different limit transitions for modifications of the classical polynomials obtained by the addition of one or two point masses at the ends of the interval of orthogonality. The connections between Jacobi, ...

Electronic structure of stoichiometric and Ar+-bombarded ZrO2 determined by resonant photoemission
(American Institute of Physics Publising LLC, 1995)
The electronic properties of thermally grown ZrO2 thin films before and after Ar+ bombardment have been studied with resonant photoemission spectroscopy using synchrotron radiation. For stoichiometric ZrO2 thin films the ...
