Chemical and oil spill rapid response modelling in the Strait of Gibraltar–Alborán Sea
(Elsevier, 2007)
A numerical model that simulates the dispersion of contaminants, including oil spills, in the Strait of Gibraltar–Alboran Sea region has been developed. The hydrodynamic is solved in ´ advance and includes a barotropic ...

Modelling surface radioactive spill dispersion in the Alboran Sea
(Elsevier, 2006)
The Strait of Gibraltar and the Albora´n Sea are the only connection between the Atlantic Ocean and the Mediterranean Sea. Intense shipping activities occur in the area, including transport of waste radionuclides and ...

Environmental modelling in the Gulf of Cadiz: Heavy metal distributions in water and sediments
(Elsevier, 2009)
The Gulf of Cadiz (GoC) connects the Atlantic Ocean and the Mediterranean Sea. An environmental study of the GoC is carried out through numerical modelling. First, a 3D baroclinic model is used to obtain the residual circulation ...

Normal-mode linear analysis and initial conditions of capillary jets
(Cambridge University Press, 2008-04-25)
The normal-mode linear analysis of an axisymmetric infinite capillary jet is generalized to account for arbitrary initial conditions. An exhaustive study of the dispersion relation reveals the parametric behaviour of all ...

Increased Cysteine Availability is Essential for Cadmium Tolerance and Accumulation in Arabidopsis Thaliana
(Wiley Open Access, 2004)
Employing genetic transformation using an Atcys-3A cDNA construct expressing the cytosolic O-acetylserine(thiol)lyase (OASTL), we obtained two Arabidopsis lines with different capabilities for supplying cysteine under metal ...

Occupational dosimetric assessment (inhalation pathway) from the application of phosphogypsum in agriculture in South West Spain
(Elsevier, 2009)
Phosphogypsum (PG) has been traditionally applied as Ca-amendment in saline marsh soils in SW Spain, where available PG has 710 ± 40 Bq kg−1 of 226Ra. This work assesses the potential radiological risk for farmers through ...

A modelling study on 137Cs and 239,240Pu behaviour in the Alborán Sea, western Mediterranean
(Elsevier, 2008)
A model for simulating the dispersion processes of 137Cs and 239,240Pu in the Alborán Sea is described. The model consists of two hydrodynamic models: a 2D depth-averaged model and a two-layer model which provide tidal and ...

Very large stochastic resonance gains in finite sets of interacting identical subsystems driven by subthreshold rectangular pulses
(American Physical Society, 2007)
We study the phenomenon of nonlinear stochastic resonance (SR) in a complex noisy system formed by a finite number of interacting subunits driven by rectangular pulsed time periodic forces. We find that very large SR gains ...

Modelling surface radioactive, chemical and oil spills in the Strait of Gibraltar
(Elsevier, 2008)
A model that simulates the dispersion of chemical/radioactive and oil spills in the Strait of Gibraltar has been developed. Water currents over the Strait have been obtained from a hydrodynamic model. Computed tides and ...

Using the finite domain remnant of the continuous spectrum to examine integrability: Effect of boundary conditions
(2003)
The aim of this work is to propose a method for testing the integrability of a model partial differential (PDE) and/or differential difference equation (DDE), by examining it in a finite but large domain. For monoparametric ...
