Effects of the static and ELF magnetic fields on the neuronal population activity in Morimus funereus (Coleoptera, Cerambycidae) antennal lobe revealed by wavelet analysis
(Elsevier Science Inc, New York, 2015)
To study the influence of a static magnetic field (SMF, 2 mT) and extremely low frequency magnetic field (ELF MF, 50 Hz, 2 mT) on the neuronal population activity, the experiments were performed on adult longhorn beetles ...
Oxygen and light accelerate recovery from SO2-induced inhibition of leaf photosynthesis and from cytoplasmic acidification
(Elsevier GmbH, 2000)
Leaves of several plant species were illuminated either in air or in a gas atmosphere with reduced oxygen content, and photosynthesis and transpiration were recorded after brief exposure to high concentrations of SO2. ...
A new electrolyte based on Tm3+-doped delta-Bi2O3-type phase with enhanced conductivity
(Elsevier Science Bv, Amsterdam, 2015)
The possibility to stabilize the delta-Bi2O3-type polymorph with high ionic conductivity by doping with Tm2O3 was investigated in this study. Five microaystalline samples were synthesized at 750 degrees C from alpha-Bi2O3 ...
Are leaf hydrogen peroxide concentrations commonly overestimated? The potential influence of artefactual interference by tissue phenolics and ascorbate
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2002)
We have examined the authenticity of two methods for determination of H2O2 in leaf tissue. We show that the high concentrations of ascorbic acid present in leaf extracts interfere with both techniques. In the chromogenic ...
Structural and electrical properties of ZnO varistors containing different spinel phases
(Elsevier Sci Ltd, Oxford, 2001)
Structural and electrical properties of ZnO varistors were investigated as a function of spinel composition. Six varistor mixtures differing only in chemical composition of spinel, were prepared by mixing separately ...
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 ...
Effects of xanthine derivatives on electroretinographic responsiveness
(Elsevier, Amsterdam, 2000)
In view of the use of synthetic propentofylline (PPF) as a protective agent in brain ischemia, its possible side effects on vision capacities have been explored by electroretinography in comparative experiments with ...
Low ascorbic acid in the vtc-1 mutant of arabidopsis is associated with decreased growth and intracellular redistribution of the antioxidant system
(Oxford Univ Press Inc, Cary, 2001)
Ascorbic acid has numerous and diverse roles in plant metabolism. We have used the vtc-1 mutant of Arabidopsis, which is deficient in ascorbate biosynthesis, to investigate the role of ascorbate concentration in growth, ...
Electroretinographic evaluation of spectral sensitivity in yellow and silver eels (Anguilla anguilla)
(Cambridge Univ Press, New York, 1998)
Although differences in visual pigments between developmental stages of the European eel are well known, the expected differences in spectral sensitivity have not been demonstrated at the electrophysiological level. In ...
Far infrared properties of PbTe doped with cerium
(Elsevier Science Sa, Lausanne, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are presented. The experimental data were numerically ...
