Does high bicarbonate supply to roots change availability of iron in the leaf apoplast?
(Springer, Dordrecht, 2002)
The role of the leaf apoplast in iron (Fe) uptake into the leaf symplast is insufficiently understood, particularly in relation to the supposed inactivation of Fe in leaves caused by elevated bicarbonate in calcareous ...
ZnO varistors from intensively milled powders
(Elsevier Sci Ltd, Oxford, 2007)
Two ways of application of intensive milling in ZnO varistors processing were compared. First was intensive milling of mixture of previously prepared constituent phases. In this case, intensive milling was applied only to ...
Changes in sterlet (Acipenser ruthenus L.) catch and length frequency distribution in the Serbian part of the Danube River during the twentieth century
(Polish Academy of Sciences, 2004)
Data from a sample of 262 sterlet (Acipenser ruthenus L.) specimens from the Serbian part of the Danube River were compared with data collected between 1948 and 1967. The recent sample was caught between September 2002 and ...
Structural - Phase transformations in bentonite after NaOH-BaCl2 treatment in conditions of water deficiency
(Silicates Industriels, 2006)
The methods of X-ray diffraction, FTIR-spectroscopy, electron microscopy, X-ray microanalysis and others were used for investigation of structural phase reorganization, which occurs in a montmorillonite-gypsum mixture ...
Germination of Iva xanthifolia, Amaranthus retroflexus and Sorghum halepense under media with microorganisms
(Journal of Plant Diseases and Proctection, Supplement, 2008)
This investigation focused on testing the germination of three weed species (Iva xanthifolia Nutt., Amaranthus retroflexus L. and Sorghum halepense (L.) Pers.) under the influence of several microorganisms: a population ...
ZnO varistors with reduced amount of additives prepared by direct mixing of constituent phases
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to reduce number of additives using new method of preparation, refered as "direct mixing of the constituent phases". The method is based on sintering of a mixture of constituent phases with the ...
Lungs: Remote inflammatory target of systemic cadmium administration in rats
(Elsevier Science Bv, Amsterdam, 2009)
Pulmonary inflammation is a biological response to cadmium entering the body via the respiratory route. Systemic administration of this metal revealed the lungs as a significant site of its disposition. In this study, the ...
Uptake and transport of foliar applied zinc (Zn-65) in bread and durum wheat cultivars differing in zinc efficiency
(Springer, Dordrecht, 2002)
Using two bread wheat (Triticum aestivum) and two durum wheat (Triticum durum) cultivars differing in zinc (Zn) efficiency, uptake and translocation of foliar-applied Zn-65 were studied to characterize the role of Zn ...
Phenolics, lignin content and peroxidase activity in Picea omorika lines
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2006)
We analyzed low molecular mass phenolics, lignin content and both soluble and cell wall bound peroxidase activity in the needles of three Picea omorika (Pancic) Purkyne lines grown in the generative seed orchard. The highest ...
Deconvolution of fluorescence spectra: Contribution to the structural analysis of complex molecules
(Elsevier Science Bv, Amsterdam, 2007)
Fluorescence spectroscopy is a sensitive analytical tool in the studies of both simple and complex molecular structures. In complex molecules, however, determining the number and position of components may give a specific ...
