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 ...
Genetic diversity and structure of the West Balkan Pramenka sheep types as revealed by microsatellite and mitochondrial DNA analysis
(Wiley-Blackwell, Malden, 2008)
Several different phenotypes of the native Pramenka sheep have been developed in the Balkan region for different environmental and socio-cultural conditions. Animals from seven West Balkan Pramenka sheep types were analysed ...
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 ...
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 ...
Application of the intergranular impedance model in correlating microstructure and electrical properties of doped BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
Microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of this material. In this study, the model of intergranular impedance ...

(Elsevier Gmbh, Munich, 2005)
A review of species in the genus Praon Haliday, 1833 is presented. Twenty described species are keyed and illustrated with scanning electron micrographs and line drawings. The Praon species presented in this work have been ...
The effect of certain exogenous growth regulators on quality of grafted grapevine rootlings
(Springer, Dordrecht, 2005)
Paclobutrazol (PB), chlormequat (CM), fenarimol (FM), and gibberellin A(3) (GA(3)) were applied as exogenous growth regulators once (1 x PB, 1 x CM, 1 x FM, 1 x GA(3)), twice (2 x PB, 2 x CM, 2 x FM, 2 x GA3) or three times ...
Oilseed rape (Brassica napus L.) genotypic variation in response to boron deficiency
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2012)
Boron efficiency of 16 oilseed rape genotypes was tested using both hydroponic and pot-soil growing techniques. From the nutrient solution experiment (0.1 and 10 mu M B), 4 representative contrasting genotypes were selected ...
Resistance of sunflower hybrids to imazamox and tribenuron-methyl
(Elsevier Sci Ltd, Oxford, 2012)
The response of the imazamox resistant and susceptible sunflower hybrids Rimi and S to imazamox and of tribenuron-methyl resistant and susceptible hybrids Rsu and S to tribenuron-methyl was investigated both in a whole-plant ...
The effect of field pea (Pisum sativum L.) companion crop management on red clover (Trifolium pratense L.) establishment and productivity
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2010)
Field pea (Pisum sativum L.) has the potential to be a suitable companion crop for the establishment of red clover (Trifolium pratense L.), as it is fast growing and is harvested early, and thus reduces the duration of ...
