A modeling study of Ra-226 dispersion in an estuarine system in south-west Spain
(Elsevier, 1994)
A numerical model to study 226Ra dispersion in the Odiel River, in which two fertilizer plants release their wastes, has been developed. The hydrodynamic equations have been solved to obtain the instantaneous water state ...

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 ...

dc motion of ac driven sine-Gordon solitons
(Elsevier, 1998-10-05)
We investigate the dependence of dc soliton motion sustained by pure ac driving in the sine-Gordon model on various parameter problems, such as frequency, initial kink velocity or relative phase. We show by means of the ...

Modelling the suspended matter dynamics in a marine environment using a three dimensional σ coordinate model: application to the eastern Irish Sea
(Elsevier, 2002)
A numerical model to study the suspended matter dynamics in the sea has been developed. The model solves the three dimensional hydrodynamic equations, that are written in normalized σ coordinates so that vertical resolution ...

Modelling the physico-chemical speciation of plutonium in the eastern Irish Sea
(Elsevier, 2000)
A numerical model to simulate the speciation of in the eastern Irish Sea is presented. The model solves the three dimensional hydrodynamic equations, using normalized σ coordinates in the vertical direction. Simultaneously, ...

Phosphogypsum Amendment Effect on Radionuclide Content in Drainage Water and Marsh Soils from Southwestern Spain
(Wiley, 2003)
Phosphogypsum (PG) is a residue of the phosphate fertilizer industry that has relatively high concentrations of 226Ra and other radionuclides. Thus, it is interesting to study the effect of PG applied as a Ca amendment on ...

A numerical model to simulate the tidal dispersion of radionuclides in the English Channel
(Elsevier, 1999)
A numerical model to simulate the tide-induced dispersion of conservative radionuclides in the English Channel has been developed. The model solves the shallow-water hydrodynamic equations and, simultaneously, the advection ...

Voltage Quality Factor for Networks Supplying Unbalanced Nonlinear Loads
(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2005)
While the common term for describing the harmonic content and the unbalanced loading of the three-phase supply is power quality, it is actually the quality of the voltage that is being addressed in most cases. The power ...

Modelling the suspended matter distribution in an estuarine system : Application to the Odiel river in southwest Spain
(Elsevier, 1996)
A numerical model which solves the advective-diffusive dispersion equation for suspended matter and includes the deposition and resuspension is presented. The model requires the simultaneous solution of the hydrodynamic ...
