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 ...
Nonlinear properties and stability of SnO2 varistors prepared by evaporation and decomposition of suspensions
(Elsevier Sci Ltd, Oxford, 2005)
SnO2 varistors doped with CoO, Cr2O3 and Nb2O5 were prepared by evaporation and decomposition of suspensions. The composition of the varistors was optimized to improve electrical properties, such as nonlinearity, leakage ...
Detection of hydrogen atom adduct of spin-trap DEPMPO. The relevance for studies of biological systems
(Amer Chemical Soc, Washington, 2005)
We proposed EPR spectroscopy using spin-trap DEPMPO as a novel method for the detection of a hydrogen atom (H-center dot) produced by chemical and biological systems. In complex EPR spectra of DEPMPO adducts in biological ...
Effects of 5-fluorouracil on erythrocytes in relation to its cardiotoxicity: Membrane structure and functioning
(Amer Chemical Soc, Washington, 2005)
In the present study, we showed that the antineoplastic drug 5-fluorouracil (5-FU) induces in vitro exposure-time/dose-dependent changes on the level of an erythrocyte's morphology, ionic balance, and membrane fluidity. ...
Organic manure stimulates biological activity and barley growth in soil subject to secondary salinization
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
A pot experiment was performed to compare the impact of organic manure on soil enzymatic activity, respiration rate and the growth of two barley cultivars (Hordeum vulgare L.) differing in their salt tolerance under a ...
Microstructural characterization of mechanically activated ZnO-Cr2O3 system
(Elsevier Sci Ltd, Oxford, 2005)
An equimolar mixtures of starting ZnO and Cr2O3 powders were mechanically activated by grinding using a planetary ball mill for various periods of time (40-320min). Formation of nanocrystalline ZnCr2O4 as normal spine] ...
