Natural and artificial radionuclides in a marine core. First results of 236U in North Atlantic Ocean sediments
(ScienceDirect, 2018-06)
There are very few data available of 236U in marine sediment cores. In this study we present the results from the first oceanic depth profile of 236U in a sediment core sampled in the North Atlantic Ocean, at the PAP site ...

Nonlinear instabilities of multi-site breathers in Klein–Gordon lattices
(Wiley online library, 2016)
In the present work, we explore the possibility of excited breather states in a nonlinear Klein–Gordon lattice to become nonlinearly unstable, even if they are found to be spectrally stable. The mechanism for this fundamentally ...

Determination of the Optical Constants of Gold Nanoparticles from Thin-Film Spectra
(American Chemical Society, 2015-04-06)
We determine the optical properties of nanocomposites comprising gold nanoparticles embedded in a titania matrix using spectroscopic ellipsometry. We then apply the spectral representation formalism due to Bergman, to ...

A set of rapid-response models for pollutant dispersion assessments in southern Spain coastal waters
(Elsevier, 2010)
Three rapid-response Lagrangian particle-tracking dispersion models have been developed for southern Spain coastal waters. The three domains cover the Gulf of Cádiz (Atlantic Ocean), the Alborán Sea (Med iterranean), and ...

Nonlinear waves in a chain of magnetically coupled pendula
(Acoustical Society of America, 2018)
A motivation for the study of reduced models like one-dimensional systems in Solid State Physics is the complexity of the full problem. In recent years our group has studied theoretically, numerically and experimentally ...

Minimal formulation of the linear spatial analysis of capillary jets: Validity of the two-mode approach
(American Physical Society, 2018)
A rigorous and complete formulation of the linear evolution of harmonically stimulated capillary jets should include infinitely many spatial modes to account for arbitrary exit conditions [J. Guerrero et al., J. Fluid ...

La mentoría en la Escuela Universitaria Politécnica de la Universidad de Sevilla
(Universidad de Cantabria, 2010-07)
Con el fin de integrar a los alumnos de nuevo ingreso, la Escuela Universitaria Politécnica de la Universidad de Sevilla ha puesto en marcha en el curso 2008-09 un Plan de Acción Tutorial (EUPAT) basado en una red en la ...

Modelling the environmental behaviour of pollutants in Algeciras Bay (south Spain)
(Elsevier, 2012)
An environmental study of Algeciras Bay is carried out through numerical modelling. First, a 2D barotrop ic model is applied to calculate tides and mean circulation. Results of this model are used by a sediment transport ...

Levels of radionuclide concentrations in benthic invertebrate species from the Balearic Islands, Western Mediterranean, during 2012–2018
(Elsevier, 2019-12)
Baseline levels of radionuclides in the marine environment of the Balearic Islands in Western Mediterranean have not been reported in literature. Because of their ecological role and acknowledged sensitivity to pollutants, ...

New classes of stable exact solutions for a nonlinear rotational DNA model
(Jagellonian University, 2010)
We consider a system of two coupled nonlinear partial differential equations for describing the rotational motions of bases in both polynucleotide chains of the DNA molecule. The model was proposed by L.V. Yakushevich and ...
