tween steady and oscillatory states, and marked sensitivity to stirring rate. Thiocyanate shows none of these features. A mechanistic explanation of the chlorite-bromide oscillations seems within reach given the reactions's similarity to the chlorite-iodide reaction and the success of numerical simulations' ' , 1 2 of batch behavior in the chlorite-bromide system. In contrast, very little is kn...

We develop a general model and the associated numerical algorithm to compute the swelling dynamics of chemo-responsive polyelectrolyte gels immersed in a reactive ionic solution kept at a non equilibrium stationary state by a permanent feed of fresh reactants. Using an autocatalytic bistable but nonoscillatory reaction, namely, the bromate-sulfite reaction, we predict that a piece of hydrogel t...

The main aim of this thesis was to study the role of the indirect actions of γ-rays and αparticles on the complexity of primary DNA damages and the repair fidelity of major DNA repair pathways: non-homologous end joining (NHEJ), homologous recombination repair (HRR) and base excision repair (BER). The complexity of radiation-induced damages increases and the proximity between damages decreases ...
