Extension of the stability criterion for dissipative optical soliton solutions of a two-dimensional Ginzburg-Landau system generated from asymmetric inputs
(IOP PUBLISHING, 2008)
The evolution and stability of dissipative optical spatial solitons generated from an input asymmetric with respect to two transverse coordinates x and y are studied. The variational approach used to investigate steady ...
INFRARED SPECTROSCOPY OF UNDOPED AND LA AND Sb DOPED BaTiO3 PREPARED BY POLYMERIC PRECURSORS METHOD
(Final Workshop COST 539, 28-30 October 2009, Aveiro, Portugal, Programme and book of extended abstracts, p 78-79, 2009)
The infrared spectra of ABO3 perovskites have been studied extensively. Factor
group analysis for BaTiO3 with cubic symmetry (space group Pm3m : O6r) predicts only
infrared bands (three triply degenerate infrared active ...
EFFECT OF SYNTHESIS METHOD ON BaTiO3 PROPERTIES
(Faculty of Technology, University of Novi Sad Bul. cara Lazara 1, 21000 Novi Sad, Serbia, 2007)
Barium titanate (BaTiO3) has been of practical interest for more than 60 years
because of its attractive properties. BaTiO3 can be prepared using different methods. It
was detected a significant influence of used method ...
Efekat neurotoksičnosti aluminijuma na elektrokortikalnu aktivnost mozga pacova / Effect of aluminium neurotoxicity on the rat brain electrocortical activity
(Acta biologica serbica - serija C: Acta physiologica et pharmacologica serbica, 2006)
The aim of our study was to investigate the electrophysiological effects of aluminium neurotoxicity. This animal model of neurodegenerative dementia was induced by chronic treatment of Wistarrats with aluminum chloride for ...
Self-stabilized spatiotemporal dynamics of dissipative light bullets generated from inputs without spherical symmetry in three-dimensional Ginzburg-Landau systems
(Physical Review A, 2007)
In order to meet experimental conditions, the generation, evolution, and self-stabilization of optical dissipative light bullets from non-spherically-symmetric input pulses is studied. Steady-state solutions of the ...
Concentrations of lead and manganese in some woody plants along M-21 road through “Fruska gora” National park
(Proceeding of 6th European Meeting on Environmental Chemistry, 6th European Meeting on Environmental Chemistry, Belgrade, Serbia and Montenegro, 2005, 06.12.-10.12., No 6, 2005)
Herbaceus plants as lead (PB) hyperaccumulators

Spectrofluorimetric Analysis of Synthetic and isolated lignin from Omorika
(22th International Symposium on Biophysic, 2004)
Lignin is the one of the main constituitive polymers of the plant cell wall that protect plant cell from different kond of stress. Lignin precursors, the plenolic alcohols, belong to the group of phenylpropanoid compounds. ...
Excitation of guided waves in materials with negative refraction
(Elsevier, 2008)
We study, both analytically and numerically, electromagnetic beam transmission through a layered structure that includes a waveguide slab of metamaterial with negative refraction. The resonant excitation of the leaky guided ...
Determination of crystalline structure of calcium carbonate obtained from drinking water / Određivanje kristalne strukture kalcijum-karbonata dobijenog iz vode za piće
(Inženjersko društvo za koroziju, Beograd, 2008)
Sample of scale which taken from house boiler is examined. This scale is made by warming drinking water from water-supply system of the -city of Belgrade - New Belgrade. Examinations on atomic absorption spectrophotometer ...
