DPR analysis of microstructural evolution of ZnO ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
It is well known that, due to their specific properties, ZnO - based materials are frequently used in electrotechnics and electronics. Since these properties are very Much dependent on the microstructural state of material ...
Rheological quantification of liposomes aggregation
(Edizioni Minerva Medica, Turin, 2005)
Aim. The aggregation of phospholipid vesicles (liposomes) in water is analyzed experimentally and theoretically and compared with the well-examined alumina dispersions. The steady-state aggregation followed rheologically ...
The effect of reversing current on the properties of copper and electrolytic copper powder II. The apparent density and flowability of powders
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The apparent density and flowability of copper powder are related to the structure of powder particles and the reversing current (RC) regimes. It was shown that the apparent density of the powders increases with the increase ...
Phase transformations and thermal effects of mechanically activated BaCO3 -TiO2 system
(Ferroelectrics, 2002)
Phase transformations and thermal effects of BaTiO 3 ceramics due to influence of mechanical activation were investigated. Equimolar mixture of BaCO 3 and TiO 2 powders was activated in high energy vibromill for various ...
The effect of new herbicides on the grain yield of inbred lines of maize
(Fresenius Environmental Bulletin, 2002)
In these experiments, the reaction of 24 inbred lines of maize to the new herbicides Equip (formasulfuron), Callisto (mesotrione) and a combination of Motivel (nicosulfuron) with Banvel 480 S (dicamba) was investigated. ...
Study of corrosion resistance of chromium-nickel steel in calcium-hypochlorite solution
(Bulletin of Electrochemistry, 2002)
The purpose of this paper is to study the corrosion resistance of different samples bf chromium-nickel steel in calcium-hypochlorite solution, by potentiodynamic method. Corrosion resistance of Cr-Ni special steels is ...
Total phenolics and phenolic acids content in low (Chrysopogon gryllus) and mediocre quality (Festuca vallesiaca) forage grasses of Deliblato Sands meadow-pasture communities in Serbia
(Czech Academy Agricultural Sciences, Prague, 2005)
Chrysopogon gryllus and Festuca vallesiaca are components of a number of meadow-pasture communities in Serbia. We performed the analyses of phenolics that influence quality and digestibility of grasses to a great extent. ...
A new Aphidius species (Hymenoptera : Braconidae : Aphidiinae) from high-montane areas of southeastern Europe
(Springer, Dordrecht, 2004)
Aphidius montenegrinus sp.n. from Serbia and Montenegro is described and illustrated. It parasitized Acyrthosiphon daphnidis Ilharco, on Daphne alpina L. The parasitoid was described and illustrated using scanning electron ...
Flowability of electrolytic copper powder
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The surface structure of powder particles, which allows free flow of copper powder, was examined. It has been shown that a sufficiently dense surface structure which permits free flow will be obtained if apparent density ...
