Estimation of parameter k(max) in fractal analysis of rat brain activity
(New York Acad Sciences, New York, 2005)
We recorded electrocortical activity in anesthetized rats and constructed kmax new self-similar time series, applying Higuchi's algorithm. The aim of this study was to estimate value of the parameter k(max). in order to ...
Aquaporins in poplar: What a difference a symbiont makes!
(Springer, New York, 2005)
The formation of ectomycorrhizas, a tight association between fine roots of trees and certain soil fungi, improves plant nutrition in a nutrient-limited environment and may increase plant survival under water stress ...
An EPR spin-probe and spin-trap study of the free radicals produced by plant plasma membranes
(Srpsko hemijsko društvo, Beograd, 2005)
Plant plasma membranes are known to produce superoxide radicals, while the production of hydroxyl radical is thought to occur only in the cell wall. In this work it was demonstrated using combined spin-trap and spin-probe ...
A phenomenological analysis of sintering kinetics from the viewpoint of activated volume
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2005)
The sintering kinetics of real systems has been viewed as a process of transport of activated volume. Activated volume is a parameter that can be used to describe mass transport during the sintering process. It defines the ...
The effect of anoxia on PolyP content of Phycomyces blakesleeanus mycelium studied by P-31 NMR spectroscopy
(New York Acad Sciences, New York, 2005)
The effect of anoxia and the respiratory chain inhibitors azide and cyanide on the polyphosphate content of Phycomyces was studied by in vivo (31)p NMR spectroscopy. Anoxia was manifested by a decrease of core polyphosphates ...
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 ...
Consecutive differences as a method of signal fractal analysis
(World Scientific Publ Co Pte Ltd, Singapore, 2005)
We propose a new method for calculating fractal dimension (DF) of a signal y(t), based on coefficients m(y)((n)), mean absolute values of its nth order derivatives (consecutive finite differences for sampled signals). We ...
Acid activation of bentonite clay in conditions of water deficiency
(Silicates Industriels, 2005)
The methods of X-ray diffraction, FTIR, electron microscopy, BET, CEC and others were used for investigation of bentonite activation with hydrochloric acid in conditions of water deficiency. It was established that during ...
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 ...
Electrodeposition and characterization of Fe-Mo alloys as cathodes for hydrogen evolution in the process of chlorate production
(Srpsko hemijsko društvo, Beograd, 2005)
Fe-Mo alloys were electrodeposited from a pyrophosphate bath using a single diode rectified AC current. Their composition and morphology were investigated by SEM, optical microscopy and EDS, in order to determine the ...
