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 ...
LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
(Elsevier, Amsterdam, 2008)
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
Soil type classification and estimation of soil properties using support vector machines
(Elsevier, Amsterdam, 2010)
Quantitative techniques for prediction and classification in soil survey are developing rapidly. The paper introduces application of Support Vector Machines in the estimate of values of soil properties and soil type ...
Parasitoids (Hymenoptera: Braconidae: Aphidiinae) Attacking Aphids Feeding on Solanaceae and Cucurbitaceae Crops in Southeastern Europe: Aphidiine-Aphid-Plant Associations and Key
(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 ...
Energy efficiency optimization of combined ventilation systems in livestock buildings
(Elsevier Science Sa, Lausanne, 2010)
Good ventilation system in livestock buildings is necessary for removing excess moisture and heat and for improving building environment in general. Natural ventilation does not require energy consumption and on the other ...
Boron uptake by the root cortex symplast of tomato and pea plants: evidence for low-boron-induced active transport
(Csiro Publishing, Clayton, 2007)
The objective of this research was to test the hypothesis of the existence of an active boron ( B) uptake into the cortical cells induced by low B supply. The uptake of B was characterised in two tomato ( Lycopersicon ...
Dehydrogenase isoenzyme polymorphism in selected almond genotypes (prunus amygdalus batsch.)
(Bulgarian Journal of Agricultural Science, 2009)
Isoenzyme polymorphism was studied in 20 almond (Prunus amygdalus Batsch.) genotypes, selected in the region of northern Serbia (Vojvodina). Five enzyme systems: alcohol dehydrogenase (ADH), formate dehydrogenase (FDH), ...
RAPD Marker Related to Elongated Fruit Shape in Pepper (Capsicum annuum L.)
(Acta Horticulturae, 2009)
Breeders develop pepper lines with different fruit shapes according to demands of market. It will be useful to develop an efficient tool for identification of fruit shape in pepper seedling. This could shorten a selection ...
Synthesis, characterization and biological activity evaluation of Pt(II), Pd(II), Co(III) and Ni(II) complexes with N-heteroaromatic selenosemicarbazones
(Elsevier Science Sa, Lausanne, 2009)
Five new complexes of Pt(II), Pd(II), Co(III) and Ni(II) with 2-pyridine(quinoline) carboxaldehyde selenose-micarbazones were synthesized and characterized. Crystal structures of Pt(II) complex with the pyridine derivative ...
Effectiveness of fungicides and an essential-oil-based product in the control of grey mould disease in raspberry
(Scientific Issues Natl Centre Agrarian Sciences, Sofia, 2012)
Field experiments were conducted in two commercial raspberry fields to evaluate effectiveness of some fungicides and an essential oil based product in the control of Botrytis fruit rot. The experiments consisted of four ...
