Effect of camphor essential oil on rat cerebral cortex activity as manifested by fractal dimension changes
(Srpsko biološko društvo, Beograd, i dr., 2008)
The aim of our study was to investigate the effect of camphor essential oil on rat cerebral cortex activity by fractal analysis. Fractal dimension (FD) values of the parietal electrocortical activity were calculated before ...
Antioxidative defense enzymes in placenta protect placenta and fetus in inherited thrombophilia from hydrogen peroxide
(Hindawi Ltd, London, 2009)
Our aim was to investigate the activities of antioxidative defense enzymes in the placenta, fetal blood and amnion fluid in inherited thrombophilia. Thrombophilia was associated with nearly threefold increase of activity ...
Aerosol Deposition of Ba0.8Sr0.2TiO3 Thin Films
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
In this work we optimized conditions for aerosol deposition of homogeneous, nano-grained, smooth Ba0.8Sr0.2TiO3 thin films. Investigation involved optimization of deposition parameters, namely deposition time and temperature ...
