Effect of bicarbonate and Fe supply on Fe nutrition of grapevine
(Taylor & Francis Inc, Philadelphia, 2000)
Grapevine grafts (Yi:lis vinifera L. cv. Riesling on rootstocks of Vitis sp. L. cv. 5BB) were grown hydroponically in complete nutrient solution (control), Fe-free nutrient solution and complete nutrient solution with added ...
Uptake of iron (Fe-59) complexed to water-extractable humic substances by sunflower leaves
(Taylor & Francis Inc, Philadelphia, 2003)
A research was carried out to evaluate the leaves' ability to utilize Fe supplied as a complex with water-extractable humic substances (WEHS) and the long-distance transport of Fe-59 applied to sections of fully expanded ...
Fractal analysis of STM images of lignin polymer obtained by in vitro synthesis
(Slovak Academy of Sciences, 2000)
Lignin, the structural polymer of the plant cell walls, is produced by free radical polymerization of phenolic alcohols, catalyzed by different peroxidases. The mechanism and the structural organization of lignin in the ...
Mechanochemical synthesis of CaTiO3 from CaCO3-TiO2 mixture
(Trans Tech Publications Ltd, 2004)
The synthesis of calcium titanate, CaTiO3, was performed by mechanical activation and thermal treatment. Milling for up to 360 minutes in a planetary ball mill mechanically activated an equimolar mixture of CaCO3 and TiO2 ...
The influence of tribophysical activation on non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., ...
Photoacoustic and optical properties of zinc-stannate thin films
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Thin films of single-phase zinc-stannate (Zn2SnO4) were grown by rf magnetron sputtering onto glass substrates. Transmission in the visible range was measured allowing determination of the energy gap and thickness of ...
Spectral sensitivity of the dogfish shark (Scyliorhinus canicula)
(Springer, Dordrecht, 2007)
The action spectrum of the electroretinographic (ERG) b-wave and the unmasked late receptor potential (LRP) were measured under a variety of conditions (isolated eyecup, detached retina, b-wave recording in fresh preparations, ...
In vitro multiplication of willow gentian (Gentiana asclepiadea L.) and the production of gentiopicrine and mangiferin
(Phyton - Annales Rei Botanicae, 2006)
A protocol for in vitro propagation of Gentiana asclepiadea was developed. The best multiplication rate was obtained with woody plant medium (WPM) supplemented with 8.9 mu M BAP (6-benzylaminopurine) and 1.1 mu M IAA ...
Microstructural properties of PZT thin films deposited on LaNiO3-coated substrates
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O-3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
(Springer Heidelberg, Heidelberg, 2008)
A single p-type crystal of the mineral, pyrite ( FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic ( PA) amplitude and phase spectra were measured using a specially ...
