Induction of peroxidases and superoxide dismutases in transformed embryogenic calli of alfalfa (Medicago sativa L.)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
Peroxidase (POD) and superoxide dismutase (SOD) enzyme activities were analyzed in non-regenerative transformed embryogenic lines of alfalfa (Medicago sativa L.) carrying wound-inducible oryzacystatin I (OC-I), wound-inducible ...
Electromechanical Switch Based on Mo6S6 Nanowires
(Amer Chemical Soc, Washington, 2008)
We investigate the structural, electronic, and transport properties of mechanically deformed Mo6S6 nanowires using a density-functional based tight binding method extended with a Green's functions formalism. We present two ...
Mechanochemical synthesis of lead magnesium niobate ceramics in iron media
(Springer, New York, 2008)
The possibility of mechanochemical synthesis of the lead magnesium niobate (PMN) powders of the composition Pb(Mg1/3Nb2/3)O-3 in iron vials was investigated. According to X-ray and energy-dispersive spectroscopy (EDS) ...
Far infrared properties of PbTe doped with Bismuth
(Springer, New York, 2008)
Far infrared reflectivity spectra of single crystal PbTe doped with Bi were measured and numerically analyzed using a fitting procedure based on a modified plasmon-phonon interaction model with two additional oscillators ...
The Electrophoretic Deposition of Lanthanum Manganite Powders for a Cathode-Supported Solid Oxide Fuel Cell in Planar and Tubular Configurations
(Wiley, Hoboken, 2008)
The purpose of this research was to obtain porous, high-quality cathodes for solid oxide fuel cells in both planar and tubular shapes. To accomplish this, cathodic electrophoretic deposition of the LaMnO3 powder (synthesized ...
Investigation of Dynamic Behavior of Brittle Solids by Discrete Systems
(Union University, Faculty of Construction Management, Belgrade, 2008)
With the remarkably rapid growth of computer capabilities and corresponding
advance of numerical algorithms as background, the landscape of the engineering and
scientific research is continually changing. In the pre-computer ...
Synthesis of BaTiO3 from a mechanically activated BaCO3-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
Germination of Iva xanthifolia, Amaranthus retroflexus and Sorghum halepense under media with microorganisms
(Journal of Plant Diseases and Proctection, Supplement, 2008)
This investigation focused on testing the germination of three weed species (Iva xanthifolia Nutt., Amaranthus retroflexus L. and Sorghum halepense (L.) Pers.) under the influence of several microorganisms: a population ...
The key threats to sturgeons and measures for their protection in the lower Danube region
(Springer, Dordrecht, 2008)
The six native sturgeon species have been commercially harvested in the Danube Basin for more than 2,000 years, with rapid decrease in catch by mid 19th century. Additional negative effect on sturgeon populations in the ...
Ordering effect of kinetic energy on dynamic deformation of brittle solids
(Elsevier, 2008)
The present study focuses on the plane strain problem of medium-to-high strain-rate loading of an idealized brittle material with random microstructure. The material is represented by an ensemble of “continuum particles” ...
