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) ...
Comparative effects of regulated deficit irrigation (RDI) and partial root-zone drying (PRD) on growth and cell wall peroxidase activity in tomato fruits
(Elsevier, Amsterdam, 2008)
The effects of regulated deficit irrigation (RDI) and partial root-zone drying (PRD) on tomato fruit growth and cell wall peroxidase activity in tomato exocarp were investigated in growth chamber conditions. The RDI treatment ...
Preparation and characterization of Me2O3-CeO2 (Me = B, Al, Ga, In) mixed oxide catalysts. 2. Preparation by sol-gel method
(Amer Chemical Soc, Washington, 2008)
The present work focuses on the combination of ceria mixed with another oxide from group III, using the sol-gel method. B2O3- Al2O3- Ga2O3- or In2O3-CeO2 mixed oxides have been prepared in order to improve the catalytic ...
Effect of dicamba on wheat haploid embryo development
(Akademiai Kiado Zrt, Budapest, 2008)
An interspecies zygote derives after wheat x maize crosses. This zygote aborts in absence of auxin stimulation. Treatment with dicamba is widely used to promote wheat haploid embryo development. We analyzed the effect of ...
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 ...
Larvicidal and antifeedant activity of some plant-derived compounds to Lymantria dispar L. (Lepidoptera : Limantriidae)
(Elsevier Sci Ltd, Oxford, 2008)
Ethanol solutions of essential oil of Ocimum basilicum and its main component, linalool (both isomer forms), all in three concentrations, as well as botanical standard Bioneem (0.5%), were tested for their toxicity and ...
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 ...
Biodiversity, utilization and management of grasslands of salt affected soils in Serbia
(Springer Heidelberg, Heidelberg, 2008)
Salt affected soils especially in the arid arid semi-arid regions of the world exhibit a significant increasing tendency. The relationship between plant/vegetation richness and soil salinity was assessed for 2 1 grassland ...
Morphophysiological traits and atrazine sensitivity in Chenopodium album L.
(John Wiley & Sons Ltd, Chichester, 2008)
BACKGROUND: A Chenopodium album L. biotype surviving in atrazine-treated Serbian corn fields (VC) was compared against atrazine-susceptible (S) and atrazine-resistant (R) standards. RESULTS: Atrazine (2 kg ha(-1)) killed ...
Inflammatory cytokines and malnutrition as related to risk for cardiovascular disease in hemodialysis patients
(Canadian Science Publishing, Nrc Research Press, Ottawa, 2008)
Malnutrition and inflammation are associated with end-stage renal disease (ESRD). Interleukin (IL)-6 and tumor necrosis factor alpha (TNF-alpha) powerfully predict death from cardiovascular disease. The aim of our study ...
