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 ...

Catalytic membrane ozonation is a hybrid process that combines filtration and catalytic ozonation. The deposited with an appropriate solid material acts as catalyst. As consequence, the contactor can act simultaneously (i.e., improving transfer/dissolution of gaseous ozone into liquid phase), well reactor oxidizing organic compounds). It be used in water wastewater treatment limiting disadvanta...

The kinetics of the oxidative decolorization of amaranth with KBrO3 acidified by H2SO4 was followed up by monitoring the decrease of the absorbance of amaranth at max = 520 nm. The reaction was carried out under pseudo-first-order conditions. The concentration of BrO3 was ca 300 greater than that of amaranth. The rate of reaction increased with increasing concentration of H2SO4 and BrO3, while...
