Local existence and uniqueness of regular solutions in a model of tissue invasion by solid tumours
In this paper we consider a nonlinear system of differential equations arising in tumour invasion which has been proposed in  M.A.J. Chaplain and A.R.A. Anderson, Mathematical modelling of tissue invasion, in Cancer ...
Mathematical modelling of cancer invasion of tissue the role and effect of nonlocal interactions
(World Scientific, 2009-02)
In this paper we consider a mathematical model of cancer cell invasion of tissue (extracellular matrix). Two crucial components of tissue invasion are (i) cancer cell proliferation, and (ii) over-expression and secretion ...
A betaine adduct of N-heterocyclic carbene and carbodiimide, an efficient ligand to produce ultra-small ruthenium nanoparticles
(Royal Society of Chemistry, 2015)
The betaine adduct of N-heterocyclic carbene and carbodiimide (ICy·(p-tol)NCN) was found to be a very efficient ligand to prepare very small (1–1.3 nm) ruthenium nanoparticles (RuNPs). The coordination of the ligand on the ...
Inhomogeneous multiscale dynamics in harmonic lattices
(American Institute of Physics, 2005)
We use projection operators to address the coarse-grained multiscale problem in harmonic systems. Stochastic equations of motion for the coarse-grained variables with an inhomogeneous level of coarse graining in both time ...
Formal derivation of dissipative particle dynamics from first principles
(American Physical Society, 2005)
We show that the Markovian approximation assumed in current particle-based coarse-grained techniques, like dissipative particle dynamics, is unreliable in situations in which sound plays an important role. As an example ...
Degradación anaerobia como sistema eficaz de eliminación de compuestos poliméricos
El polietilenglicol se ha identificado tradicionalmente como un compuesto recalcitrante y dificilmente biodegradable. En este trabajo se ha determinado la biodegradabilidad de polietilenglicol, de pesos moleculares medios ...
In Vitro and in Vivo Study of Poly(Lactic–co–Glycolic) (PLGA) Membranes Treated with Oxygen Plasma and Coated with Nanostructured Hydroxyapatite Ultrathin Films for Guided Bone Regeneration Processes
(Molecular Diversity Preservation International (MDPI), 2017)
The novelty of this study is the addition of an ultrathin layer of nanostructured hydroxyapatite (HA) on oxygen plasma modified poly(lactic–co–glycolic) (PLGA) membranes (PO2) in order to evaluate the efficiency of this ...
