Secuencia cronoestratigráfica del Pleistoceno Superior en Sierra Morena: la cueva de La Sima (Constantina, Sevilla)
(Sociedad Geológica de España, 2002)
La Sima of Constantina, located at the northermost part of Seville province, is a karstic cave with a thick terrigenous and chemical (f/owstone) record. These sedimentary formations are representative of the Late Quaternary ...

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 ...

In situ mechanical, temperature and gas exposure treatments of materials combined with variable energy positron beam techniques
(ScienceDirect, 2002-06-21)
An overview is given of the extension of the Delft variable energy positron (VEP) beam facility with equipment for in situ heating, cooling, 4-point bending, hydrogen permeation and gas ad- and absorption of bulk materials, ...

Soliton ratchets
(2002)
The mechanism underlying the soliton ratchet, both in absence and in presence of noise, is investigated. We show the existence of an asymmetric internal mode on the soliton profile that couples, through the damping in the ...

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 ...

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 ...

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 ...

Structural effects due to the incorporation of Ar atoms in the lattice of ZrO2 thin films prepared by ion beam assisted deposition
(ScienceDirect, 2002-09)
Two sets of ZrO2 thin films have been prepared at room temperature by ion beam induced chemical vapour deposition and subsequently annealed up to 1323 K. The two sets of samples have been prepared by using either O2+ or ...

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, ...
