Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Taylor & Francis Ltd, Abingdon, 2005)
Increasing demands on the quality of electronic ceramics requires a well-controlled correlation between particle morphology and processing conditions. Since mechanical activation is one of the methods for modification of ...
Isolation and characterization of bacterial flora from farmhouse fermented milk products of Serbia and Montenegro / Izolacija i karakterizacija bakterijske flore iz autohtonih fermentisanih proizvoda Srbije i Crne Gore
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2005)
The natural community of lactic acid bacteria isolated from farmhouse fermented milk products has been investigated. In such products, where no starters are added, fermentation occurs as a result of natural flora present ...
Monoctonus leclanti sp n. (Hymenoptera : Braconidae : Aphidlinae) from high-montane areas of southeastern Europe, and key to related species
(Entomologica Fennica, 2002)
Monoctonus leclanti sp. n., a parasitoid of Delphiniobium junackianum Karsch. (Hemiptera: Aphididae) on Aconitum toxicum bosniacum and Aconitum pentheri in the high mountains of the Balkans is described. The species is an ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Srpsko hemijsko društvo, Beograd, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
Weed vegetation of small grain crops in Serbia: environmental and human impacts
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2009)
Weed flora of winter and spring small grain crops (wheat, barley, oats, and rye) was surveyed in lowland and mountainous areas of the central part of Serbia, which are dissimilar in environmental conditions, primarily ...
Water-yield relations of maize (Zea mays L) in temperate climatic conditions
(Maydica, 2011)
A field study was carried out from 2001 to 2007 in order to determine the water-yield relationship of maize in the Vojvodina region, a northern part of the Serbia Republic. The yield response factor (K-y) was calculated ...
Kinetics of Cu2+ binding to the poly(acrylic acid) hydrogel
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Isothermal kinetics of copper (ion) binding to poly(acrylic acid) (PAA) hydrogel at 20, 25, 35 and 45 C was investigated. Isothermal conversions and kinetic curves of Cu2+ binding to the PAA hydrogel were determined. It ...
Morphological and molecular identification of potato cyst nematode populations in Serbia / Morfološka i molekularna identifikacija populacija cistolikih nematoda krompira u Srbiji
(Srpsko biološko društvo, Beograd, i dr., 2010)
Quarantine species such as potato cyst nematodes Globodera rostochiensis and G. pallida are present in Serbia since 1999 and 2005, respectively. These nematodes are sibling species and their morphological identification ...
Complexes of iron(II), iron(III) and zinc(II) with condensation derivatives of 2-acetylpyridine and oxalic or malonic dihydrazide. Crystal structure of tris[(1-(2-pyridyl)ethylidene)hydrazine]iron(II) perchlorate
(Springer, Dordrecht, 2005)
Complexes of zinc and iron with N', N'(2)- bis[(1E)-1-(2-pyridyl) ethylidene] ethanedihydrazide (H(2)L1) and N', N'(2)-bis[( 1E)-1-(2-pyridyl) ethylidene] propanedihydrazide (H(2)L2) were prepared. Zn-II complexes with ...
Water quality in semi-intensive carp production system using three different feeds
(Bulgarian Journal of Agricultural Science, 2010)
In the era of growing demand for sustainable usage of water, all types of aquaculture systems are under reconsideration. Until recently semi-intensive production was concerned to be one of the least polluting. Nowadays, ...
