Influence of mechanical activation on structural and electrical properties of sintered MgTiO3 ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
The aim of this work was to analyze the influence of mechanical activation on the MgCO3-TiO2 system. Mixtures of MgCO3-TiO2 were mechanically activated for 15, 30, 60 and 120 minutes in a planetary ball mill and after that ...

Synthesis, characterization and biological activity evaluation of Pt(II), Pd(II), Co(III) and Ni(II) complexes with N-heteroaromatic selenosemicarbazones
(Elsevier Science Sa, Lausanne, 2009)
Five new complexes of Pt(II), Pd(II), Co(III) and Ni(II) with 2-pyridine(quinoline) carboxaldehyde selenose-micarbazones were synthesized and characterized. Crystal structures of Pt(II) complex with the pyridine derivative ...
Phylogenetic relationships among Praini (Hymenoptera : Braconidae : Aphidiinae) aphid parasitoids, with redescription of two species
(Brill Academic Publishers, Leiden, 2006)
Phylogenetic relationships among four genera and 25 species of the tribe Praini (Braconidae: Aphidimae) were investigated on the basis of 15 characters (13 morphological and two life history characters) using parsimony ...
Comparative effects of regulated deficit irrigation (RDI) and partial root-zone drying (PRD) on growth and cell wall peroxidase activity in tomato fruits
(Elsevier, Amsterdam, 2008)
The effects of regulated deficit irrigation (RDI) and partial root-zone drying (PRD) on tomato fruit growth and cell wall peroxidase activity in tomato exocarp were investigated in growth chamber conditions. The RDI treatment ...
A leaf spot and blight of greenhouse tomato seedlings incited by a Herbaspirillum sp.
(Amer Phytopathological Soc, St Paul, 2007)
A leaf spot and blighting were observed on leaves of tomato transplants from a producer in Florida in 2001 and 2002. A nonfluorescent bacterium was isolated consistently from affected tissue. The typical bacterium was a ...
Anatomical Injury Induced by the Eriophyid Mite Aceria anthocoptes on the Leaves of Cirsium arvense
(Springer, Dordrecht, 2006)
Anatomical injury of the leaves of the invasive species, Cirsium arvense (L.) Scop., caused by the eriophyid mite Aceria anthocoptes (Nal.), which is the only eriophyid mite that has been recorded on C. arvense worldwide, ...
Effect of dicamba on wheat haploid embryo development
(Akademiai Kiado Zrt, Budapest, 2008)
An interspecies zygote derives after wheat x maize crosses. This zygote aborts in absence of auxin stimulation. Treatment with dicamba is widely used to promote wheat haploid embryo development. We analyzed the effect of ...
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 ...
Structure and thermal behavior of the layered zincophosphate [NH3-CH2-CH(NH3)-CH3](ZnPO4)(2)
(Elsevier Science Sa, Lausanne, 2009)
A zinc phosphate with the composition [NH3-CH2-CH(NH3)-CH3](ZnPO4)(2), containing the doubly protonated 1,2-diaminopropane (abbr. HDAP), was synthesized by hydrothermal crystallization of zinc nitrate, phosphoric acid, ...
