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 ...
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 ...
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 ...
Effect of gibberellic acid on total antioxidant activity during chenopodium rubrum l. Ontogenesis in vitro
(Srpsko biološko društvo, Beograd, i dr., 2009)
Total antioxidant activity (TAA) represents the combined ability of diverse antioxidants present in a sample of plant material to scavenge free radicals. Chenopodium rubrum L. sel. 184 is a qualitatively short-day plant; ...
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 : ...
Anomalous lateral beam shift and total absorption due to excitation of surface waves in materials with negative refraction
(EUROPEAN PHYSICAL JOURNAL D, 2006)
We studied electromagnetic beam reflection from layered structures that include materials with negative refraction. Excitation of leaky surface waves leads to the formation of anomalous lateral shifts in the reflected beams ...
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 ...
Microstructure and Dielectric Properties of Lanthanum Doped Barium Titanate
(6th Workshop COST 539, 23-25. February 2009, Madrid, Spain, Programme and book of abstracts, p 64-65, 2009)
Barium titanate has a special place in the group of ferroelectric perovskites because it can be formulated in a large number of systems and solid solutions that provide a wide range of various applications. The perovskite ...
Sezonska horizontalna distribucija i abundancija vrsta familija Temoridae u Bokokotorskom zalivu
(Srpsko društvo za zaštitu voda, 2008)
U Bokokotorskom zalivu registrovane su dvije vrste Copepoda iz familije Temoridae: Temora stylifera (Dana, 1849) i Temora longicornis (Müller 1792). U radu dajemo podatke o horizontalnoj distribuciji i abundanciji ovih ...
