Weed vegetation in the north-western Balkans: diversity and species composition
(Wiley, Hoboken, 2009)
P>Surveys of weed vegetation of the western Balkan peninsula (1939-2006) were used to study changes in species composition. A large data set of arable weed vegetation was compiled and analysed with direct and indirect ...
Composition and radical-scavenging activity of Thymus glabrescens Willd. (Lamiaceae) essential oil
(Wiley, Hoboken, 2008)
BACKGROUND: Knowledge about the chemical and therapeutic properties of Thymus glabrescens Willd. (Lamiaceae) is scarce and inconsistent. Therefore the main objectives of this study were to determine the yield and chemical ...
Improved efficacy of newly formulated bacteriophages for management of bacterial spot on tomato
(Amer Phytopathological Soc, St Paul, 2003)
Bacteriophages are currently used as an alternative method for controlling bacterial spot disease on tomato incited by Xanthomonas campestris pv. vesicatoria. However, the efficacy of phage is greatly reduced due to its ...
Characterization and PCR-based typing of Xanthomonas campestris pv. vesicatoria from peppers and tomatoes in Serbia
(Springer, Dordrecht, 2004)
During the last two decades bacterial strains associated with necrotic leaf spots of pepper and tomato fruit spots were collected in Serbia. Twenty-eight strains isolated from pepper and six from tomato were characterized. ...
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 ...
Effect of different fermentation parameters on bioethanol production from corn meal hydrolyzates by free and immobilized cells of Saccharomyces cerevisiae var. ellipsoideus
(Wiley, Hoboken, 2009)
BACKGROUND: Bioethanol produced from renewable biomass, such as corn meal, is a biofuel that is both renewable and environmentally friendly. Significant scientific and technological investments will be needed to achieve ...
Incidence and Distribution of Iris yellow spot virus on Onion in Serbia
(Amer Phytopathological Soc, St Paul, 2009)
In a survey to determine the presence and distribution of It-is yellows, spot virus (IYSV) in greenhouse ornamentals and onion field crops in 14 districts of Serbia as well as on imported ornamental plants, 1,574 samples ...
Heavy metals in soils: Distribution, relationship with soil characteristics and radionuclides and multivariate assessment of contamination sources
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The study is dealing with the distribution and the origin of heavy metals (Cd, Cr, Cu, Mn, Ni, Pb and Zn) in soils from a priori non-polluted areas. Positive correlations with organic matter and clay content but not with ...
Structural and electrical properties of sintered zinc-titanate ceramics
(Elsevier Sci Ltd, Oxford, 2009)
The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO(2) were mechanically activated in a planetary ...
Light transmission through fiber post: The effect on adhesion, elastic modulus and hardness of dual-cure resin cement
(Elsevier Sci Ltd, Oxford, 2009)
Objectives. The aim of this study was to investigate the effect of fiber post light transmitting ability to the continuity of resin cement-root dentin (C-RD) and resin cement-fiber post (C-FP) interface, elastic modulus ...
