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 ...
The environmental impact of viticulture: "The influence of the biofertilizer type on wine quality and soil microbiological activity"
(Int Soc Horticultural Science, Leuven 1, 2004)
A trial was conducted in variety/rootstock Merlot/SO 4 in the vineyard district of Jagodina. At the beginning of grapevine vegetation, microbiological fertilizers (A-Az. chroococcum, AH-Az. chroococcum + humate, ABC-Az. ...
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 ...
Electrical properties of screen printed BaTiO3 thick films
(Elsevier Sci Ltd, Oxford, 2004)
The deposition of thick film pastes by screen-printing is a relatively simple and convenient method to produce thicker layers with thickness up to 100 mum. In the present work, the barium titanate thick films were prepared ...
An analytical approach to the uniqueness problem of hot-wire probes to measure simultaneously three velocity components
(IOP Publishing Ltd, Bristol, 2004)
The uniqueness range of hot-wire probes to simultaneously measure all three velocity components is analysed analytically. Expressions defining the uniqueness cone half-angle are presented for triple as well as for quadruple ...
Nectar production in three melliferous species of Lamiaceae in natural and experimental conditions
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2004)
The nectar production of Lamium maculatum, Lamiastrum galeobdolon and Ajuga reptans was evaluated by determining the Index of nectar production (INP), total nectar quantity per flower during 24h, nectar sugar concentration, ...
Identification of phytoplasmas associated with grapevine yellows in serbia
(Wiley, Hoboken, 2004)
The molecular identification and characterization of phytoplasmas from infected grapevines in four locations in Serbia are reported. Phytoplasmas were detected and identified by restriction fragment length polymorphism ...
Calorimetric study of room temperature adsorption of N2O and CO on Cu(II)-exchanged ZSM5 zeolites
(Elsevier, Amsterdam, 2004)
Copper ion-exchanged ZSM5 zeolites have been prepared with different cooper loadings from under- to over-exchanged levels. The adsorptions of N2O and CO at 303 K have been studied using calorimetric method and infrared ...
The effect of reversing current on the properties of copper and electrolytic copper powder. I. The morphology of powder particles
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The selective dissolution of copper dendrites during electrodeposition by reversing current was discussed and the effects on the morphology of copper powder particles were elucidated.
Investigation of kernel oils of Quercus robur and Quercus cerris
(Springer, New York, 2004)
The kemel oils of Quercus robur and Quercus cerris were obtained by Soxhlet extraction using petroleum ether. Oil yields were found to be 5.2-5.6% and 4.3-4.8% for Q. robur and Q. cerris kemel, respectively (expressed in ...
