Influence of photic environment on the form of the fish electroretinographic off-response
(New York Acad Sciences, New York, 2005)
Scotopic electroretinogram of dogfish shark (Scylliorhinus canicula) and eel (Anguilla anguilla) is characterized by a negative off-response, changing in sign under photopic condition. It increased under the effect of ...
Mycorrhiza formation enhances adaptive response of hybrid poplar to drought
(New York Acad Sciences, New York, 2005)
Mycorrhized and nonmycorrhized plants of hybrid poplar (Populus tremula L. x Populus tremuloides Mich) were cultivated in petri dishes until the amount of water became limiting (detected by a decrease of photosynthetic ...
Morphological characteristics of mechanically processed ZnO and MnO2 powder mixtures
(Elsevier Science Sa, Lausanne, 2009)
The evolution of structural-morphological characteristics of ZnO + 1 wt.% MnO2 and ZnO + 10 wt.% MnO2 samples during prolonged mechanical treatment (MT) was investigated by X-ray, AFM, LPS, SEM and IR methods. Changes in ...
Characterization of enzymatically synthesized diferulate
(New York Acad Sciences, New York, 2005)
Horseradish peroxidase was used to synthesize diferulates by a procedure in which ethyl ferulate was used as substrate. Four different forms were obtained, of which two dominant were the 5-5' and 8-5' diferulate. Fluorescence ...
Mechanochemical synthesis of PZT powders
(Elsevier Science Sa, Lausanne, 2003)
PZT ceramic powders were successfully prepared from the mixture of PbO, ZrO2 and TiO2 by mechanochemical synthesis in a planetary ball mill, under different milling conditions. Phase evolution during synthesis was monitored ...
Drought and oxidative load in the leaves of C-3 plants: a predominant role for photorespiration?
(Oxford Univ Press, Oxford, 2002)
Although active oxygen species are produced at high rates in both the chloroplasts and peroxisomes of the leaves Of C-3 plants, most attention has focused on the potentially damaging consequences of enhanced chloroplastic ...
Synthesis and characterization of MoOx-Pt/C and TiOx-Pt/C nano-catalysts for oxygen reduction
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The oxygen reduction reaction (ORR) was studied at carbon supported MoOx-Pt/C and TiOx-Pt nanocatalysts in 0.5 mol dm(-3) HClO4 solution, at 25 degrees C. The MoOx-Pt/C and TiOx-Pt/C catalysts were prepared by the polyole ...
Induction of peroxidases and superoxide dismutases in transformed embryogenic calli of alfalfa (Medicago sativa L.)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
Peroxidase (POD) and superoxide dismutase (SOD) enzyme activities were analyzed in non-regenerative transformed embryogenic lines of alfalfa (Medicago sativa L.) carrying wound-inducible oryzacystatin I (OC-I), wound-inducible ...
Mechanochemical synthesis of lead magnesium niobate ceramics in iron media
(Springer, New York, 2008)
The possibility of mechanochemical synthesis of the lead magnesium niobate (PMN) powders of the composition Pb(Mg1/3Nb2/3)O-3 in iron vials was investigated. According to X-ray and energy-dispersive spectroscopy (EDS) ...
The Electrophoretic Deposition of Lanthanum Manganite Powders for a Cathode-Supported Solid Oxide Fuel Cell in Planar and Tubular Configurations
(Wiley, Hoboken, 2008)
The purpose of this research was to obtain porous, high-quality cathodes for solid oxide fuel cells in both planar and tubular shapes. To accomplish this, cathodic electrophoretic deposition of the LaMnO3 powder (synthesized ...
