Influence of mechanical activation on microstructure and crystal structure of sintered MgO-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100°-1400°C for 2h. The decrease in powder's ...
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 ...
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 ...

(Oxford Univ Press Inc, Cary, 2010)
Original information oil aphidiine braconids attacking aphids feeding on Solanaceae (i.e., Capsicum annuum L., Lycium europaeum, L., Lycopersicon esculentum Miller, Solanum spp.) and Cucurbitaceae (i.e., Citrullus vulgaris ...
Pruning effect on content of quercetin and catechin in berry skins of cv. Blaufrankisch (Vitis vinifera L.)
(Turkish Journal of Agriculture and Forestry, 2010)
The effect of pruning severity on quercetin and catechin content in berry skins of cv. Blaufrankisch (Vitis vinifera L.) was studied over 3 years. Different crop levels and canopy structures were obtained by retaining 8, ...
Ca-alginate hydrogel mechanical transformations - The influence on yeast cell growth dynamics
(Elsevier, Amsterdam, 2007)
A mathematical model was formulated to describe yeast cell growth within the Ca-alginate microbead during air-lift bioreactor cultivation. Model development was based on experimentally obtained data for the intra-bead cell ...
Benefits of Environmental Conditions for Growing Coriander in Banat Region, Serbia
(SAGE Publishing, 2011)
As one of the oldest multi-purpose plants (spice, aromatic, honey and medicinal), coriander is widespread across Europe. Although in Serbia there are favorable conditions fir its growth and development, it is grown on ...
Morphogenetic responses of embryo culture of wheat related to environment culture conditions of the explant donor plant
(Univ Sao Paolo, Cerquera Cesar, 2010)
Availability of immature embryos as explants to establish wheat (Triticum aestivum L.) by tissue culture can be limited by climatic factors and the lack of high quality embryos frequently hampers experimentation. This study ...
Trichodoridae (Nematoda : Triplonchida) from the Tara National Park, Serbia, and proposal of Trichodorus pseudobursatus n. sp.
(Brill Academic Publishers, Leiden, 2008)
A survey for plant-root parasites in Tara National Park, Serbia, revealed the widespread occurrence of Trichodoridae, present in nearly one-third of the samples. Several species appeared to belong to the Trichodorus aequalis ...
Quantification of transfer of U-238, Ra-226, Th-232, K-40 and Cs-137 in mosses of a semi-natural ecosystem
(Elsevier Sci Ltd, Oxford, 2010)
There is a lack of appropriate data on transfer of some radionuclides on many terrestrial biota groups. To expand the available data concentration ratios of U-238, Ra-226, Th-232, K-40 and Cs-137 in mosses are presented ...
