Moving breathers in a bent DNA model
(2002)
We study the properties of moving breathers in a bent DNA model with short range interaction, due to the stacking of the base pairs, and long range interaction, due to the finite dipole moment of the bonds within each ...

Influence of moving breathers on vacancies migration
(Elsevier, 2003)
A vacancy defect is described by a Frenkel-Kontorova model with a discommensuration. This vacancy can migrate when interacts with a moving breather. We establish that the width of the interaction potential must be larger ...

Stationary and moving breathers in a simplified model of curved alpha--helix proteins
(2002)
The existence, stability and movability of breathers in a model for alpha-helix proteins is studied. This model basically consists a chain of dipole moments parallel to it. The existence of localized linear modes brings ...

Moving discrete breathers in a Klein–Gordon chain with an impurity
(2002)
We analyse the influence of an impurity in the evolution of moving discrete breathers in a Klein–Gordon chain with non-weak nonlinearity. Three different types of behaviour can be observed when moving breathers interact ...

First spectral emissivity study of a solar selective coating in the 150–600 1C temperature range
(ScienceDirect, 2013-10)
A complete experimental study of temperature dependence of the total spectral emissivity has been performed, for the first time, for absorber–reflector selective coatings used in concentrated solar power (CSP) systems for ...

Modelling the physico-chemical speciation of plutonium in the eastern Irish Sea: a further development
(Elsevier, 2002)
A numerical full three-dimensional model previously developed to simulate the physico-chemical speciation of plutonium in the eastern Irish Sea has been improved. The model solves simultaneously the hydrodynamic equations, ...

Redissolution and long-term transport of radionuclides released from a contaminated sediment: a numerical modelling study
(Elsevier, 2003)
A numerical model based upon residual circulation has been developed to simulate the long-term (years) transport of non-conservative radionuclides in the English Channel. The transfer of radionuclides between water, suspended ...

A particle-tracking method for simulating the dispersion of non-conservative radionuclides in coastal waters
(Elsevier, 2002)
A particle-tracking method has been used to simulate the dispersion of non-conservative radionuclides in the sea. Three dimensional turbulent diffusion and the interactions between water, suspended matter and bottom sediments ...

Moving breathers in a DNA model with competing short and long range dispersive interactions
(2002)
Moving breathers is a means of transmitting information in DNA. We study the existence and properties of moving breathers in a DNA model with short range interaction, due to the stacking of the base pairs, and long range ...

The enhancement of Ra-226 in a tidal estuary due to the overation of fertilizer factories and redissolution from sediments: Experimental results and a modelling study
(Elsevier, 2002)
The presence of 226Ra in a tidal estuary formerly affected by direct discharges from a phosphate fertilizer complex has been investigated. In general, activity levels are lower than those detected when direct discharges ...
