Chocolate – A Bittersweet Antioxidant
(The Society of Physical Chemists of Serbia, 2008)
We studied the positive health effect of different chocolates (antioxidative effects on stable
free radicals, reactive oxygen species (ROS) and for prevention of lipid peroxidation). The
results show that all chocolates ...
Spatiotemporal optical instabilities in nematic solitons
(Optics Express, 2005)
We investigate numerically the propagation of self-trapped optical beams in nematic liquid crystals. Our analysis includes both spatial and temporal behavior. We display the formation of stable solitons in a narrow threshold ...
Guided modes in left-handed waveguides
(OPTICS COMMUNICATIONS, 2008)
We investigate basic properties of linear guided modes in a waveguide slab with the core of a material with simultaneously negative effective permittivity and permeability surrounded by a normal dielectric cladding. The ...
Cerium Oxide Based Nanometric Powders: Synthesis and Characterization
(Science of Sintering, 2007)
Nanometric powders of solid solutions of cerium oxide were obtained by a modified
glycine nitrate procedure. Solid solutions of the host compound CeO2 with one or more
dopants in the lattice were synthesized. Rare earth ...
Oxalate oxidase and non-enzymatic compounds of the antioxidative system in young Serbian spruce plants exposed to cadmium stress
(Srpsko biološko društvo, Beograd, i dr., 2008)
We studied changes in the concentrations of ascorbate and glutathione, composition of soluble phenolics, and activity of oxalate oxidase in 75-day-old Serbian spruce plants after exposure to 5 mu M and 50 mu M cadmium for ...
Influence of lanthanum doping on properties of BaTiO3 prepared from organometallic complex
(5th Workshop COST 539, 1 September 2008, Manchester, UK, abstracts and CD proceedings, 2008)
Barium titanate is the first discovered ferroelectric ceramic and one of the most widely used material for various applications. Doping of BaTiO3 (BT) ceramics is very important for obtaining very interesting characteristics ...
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 ...
RAMAN STUDY OF FERROELECTRIC BISMUTH LAYER-OXIDE ABi4Ti4O15 PREPARED BY THE MECHANOCHEMICAL SYNTHESIS
(Workshop Fabrication, Properties & Applications of Electroceramic Nanostructures, Abstracts June 26-28,2008 Genoa, Italy, 2008)
Ferroelectric materials have innumerable properties related totheir spontaneus
polarization, for instance. pyre- and piezoelectricity, which are used for various sensors and
actuators il 1. BaBi4Ti4O12 (BBT) is an r : ...
Changes in activities of antioxidant enzymes during Chenopodium murale seed germination
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2008)
The activities and isoenzyme pattern of catalase (CAT), superoxide dismutase (SOD) and peroxidase (POD) have been studied during germination of Chenopodium murale seeds. CAT and SOD activities were similar in dry seeds and ...
Role of fructose in the adaptation of plants to cold-induced oxidative stress
(Springer, New York, 2008)
This work presents findings, which indicate important role of fructose, fructose 6-phosphate (F6P), and fructose 1,6-bisphosphate (FBP) in preservation of homeostasis in plants under low temperature. Cold combined with ...
