AB  - Interaction of a TEA CO2laser, operating at 10.6 μm wavelength and pulse length  of  100  ns,  with titanium  target  (implant),  in  nitrogen  and  carbon-dioxide  gas  ambience  was  studied.  The  Ti-surface  modifications  were studied  at  moderate  fluence  (~17J/cm2)  and  intensity  (~60MW/cm2) regime.The energy absorbed from the laser beam was partially convertedto thermal  energy,  which  generated  a  series  of  effects,  such  as  melting, vaporization  of  the  molten  material,  shock  waves,  etc.  The  following  Ti-surface  changes  and  phenomena  were  observed:  (i)  superficial  damages  in both   atmospheres;   (ii)   creation   of   cone-and   hill-like   structures   in atmosphere of N2and CO2, respectively; (iii) possible formation of TiN, Ti-oxide(s)  and,  Ti-carbide  layers,  in  N2and  CO2gas,  respectively  and,  (iv) occurrence  of plasma  inboth  gas  ambiences.  It  can  be  concluded  that  the applied laser fluence was high  enough to produce effective modification  of the Ti-implant target in nitrogen as well as in carbon-dioxide gas. Creation of plasma may provide sterilization effect.

AB  - The aim of this study is to describe the effect of geographical varieties on the transport of lead and cadmium in the air. During period between 1997- 2006, the concentrations of lead in suspended in the air at 5 measuring sites in Serbia were measured. The minimal measured daily concentrations of lead ranged from 0,42 μg/m3 (2002.) in Kraljevo. The maximal measured daily concentrations of lead to 251,8 μg/m3 (2004.) in Belgrade. During the period between 1997-2006., the concentrations of cadmium in suspended in the air at 5 measuring sites in Serbia were measured. The minimal measured daily concentrations of cadmium ranged from 0,1 μg/m3 (1999) in Kraljevo. The maximal measured daily concentrations of lead to 42,0 μg/m3 (2000) in Belgrade. Results from our experiments demonstrated that when rapid infiltration conditions or a rainstorm exist, particle-facilitated transport of contaminants is likely to the dominant metal transport pathway influenced by acid rain.
