Influence of carbohydrate source on Nepeta rtanjensis growth, morphogenesis, and nepetalactone production in vitro
(Brill Academic Publishers, Leiden, 2005)
A wide range of sucrose, fructose, and glucose levels in culture media was tested in vitro in order to determine those that provide optimum growth, morphogenesis, and the production of secondary metabolites in Nepeta ...
Kinetics of the hydrogen evolution reaction on Fe-Mo film deposited on mild steel support in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The mechanism and kinetics of the hydrogen evolution reaction were studied. in 1.0 mol dm(-3) NaOH solution on Fe-Mo alloy electrodes prepared by electrodeposition at constant current densities from a pyrophosphate bath. ...
Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Taylor & Francis Ltd, Abingdon, 2005)
Increasing demands on the quality of electronic ceramics requires a well-controlled correlation between particle morphology and processing conditions. Since mechanical activation is one of the methods for modification of ...
Modeling of the migration of the European glass eel
(New York Acad Sciences, New York, 2005)
The characteristics of glass eel migration at the mouth of river Bojana have been investigated by seasonal field studies from February to April 1998. Samples were collected by two fyke nets, one on each riverside, for 12 ...
Nonenzymatic reaction of dihydroxyacetone with hydrogen peroxide enhanced via a Fenton reaction
(New York Acad Sciences, New York, 2005)
An analysis of the reaction of dihydroxyacetone with hydrogen peroxide was performed using HPLC with electrochemical and spectrophotometric detection and EPR spectroscopy of the reactants and products. Glycolate production ...
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 ...
Spectral analysis of cerebellar activity after acute brain injury in anesthetized rats
(Nencki Institute of Experimental Biology, 2005)
We investigated cerebellar electrocortical activity before and after unilateral brain injury in anesthetized rats. Spectral analysis of cerebellar activity was obtained by Fast Fourier Transformation. There was a dominance ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, 2005)
In this paper a practical approach to the analysis of sintering of BaTiO3 using the Master Sintering Curve concept has been presented. Non-isothermal sintering of high-purity non-doped BaTiO3 ceramics was monitored using ...
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 ...
Somatic embryogenesis in Chenopodium rubrum and Chenopodium murale in vitro
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2005)
In order to establish an efficient system for in vitro plant regeneration of a short day plant Chenopodium rubrum L. and a long day plant Chenopodium murale L., optimum culture conditions for somatic embryogenesis were ...
