Mechanism of Fe uptake by the leaf symplast: Is Fe inactivation in leaf a cause of Fe deficiency chlorosis?
(Springer, Dordrecht, 1999)
The mechanism of iron (Fe) uptake from the leaf apoplast into leaf mesophyll cells was studied to evaluate the putative Fe inactivation as a possible cause of Fe deficiency chlorosis. For this purpose, sunflower (Helianthus ...
Light-induced transient ion flux responses from maize leaves and their association with leaf growth and photosynthesis
(Wiley, Hoboken, 2005)
Net fluxes of H+, K+ and Ca2+ ions from maize (Zea mays L.) isolated leaf segments were measured non-invasively using ion-selective vibrating microelectrodes (the MIFE technique). Leaf segments were isolated from the blade ...
Spectral and dose dependence of light-induced ion flux responses from maize leaves and their involvement in leaf expansion growth
(Oxford Univ Press, Oxford, 2007)
Two types of segments (intact leaf tissue and isolated mesophyll tissue respectively) were isolated from basal (still growing) and tip (non-growing) maize leaf regions. The leaf segments were exposed to different light ...
Tailoring of morphology and orientation of LaNiO3 films from polymeric precursors
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to prepare lanthanum nickel oxide (LaNiO3, LNO) thin films of different morphology and orientation. The precursor solutions were prepared by a chemical method from citric salts of lanthanum and ...
Synthesis and Biological Activities of Thio-avarol Derivatives
(Amer Chemical Soc, Washington, 2008)
Eleven new thio-avarol derivatives (3-13) were synthesized. Their antimicrobial, brine shrimp lethality, and free-radical scavenging activities and acetylcholinesterase inhibition, together with 12 already reported ...
Synthesis, characterization and electrocatalytical behavior of Nb-TiO2/Pt nanocatalyst for oxygen reduction reaction
(Elsevier Science Bv, Amsterdam, 2010)
In order to point out the effect of the support to the catalyst for oxygen reduction reaction nano-crystalline Nb-doped TiO2 was synthesized through a modified sol-gel route procedure. The specific surface area of the ...
Decline in the Index of Biotic Integrity of the Fish Assemblage as a Response to Reservoir Aging
(Springer, Dordrecht, 2009)
The fish assemblage from reservoir Medjuvrsje was monitored over the 1955-2000 period. The Medjuvrsje Reservoir is one of the oldest Serbian reservoirs formed in 1953. Ichthyofauna was sampled in 1955, 1984, 1991 and 2000. ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb(0.9)Sn(0.1)Te doped with 0.4 ...
Structure study of nanosized La- and Sb-doped BaTiO3
(Elsevier Science Sa, Lausanne, 2010)
Lanthanum and antimony doped barium titanate powders were prepared by polymeric precursors method through Pechini process. Obtained powder was pressed into pellet and sintering was performed at 1300 degrees C for 8 h. The ...
Far infrared properties of sintered NiO
(Elsevier Sci Ltd, Oxford, 2007)
Far infrared reflection spectra of NiO polycrystals sintered at 1100 degrees C for various times (30-240 min) were measured at room temperature using a FTIR Spectrometer-Brucker 113V. The measured spectra depended on the ...
