Senescence-related changes in catalase, peroxidase and ascorbic acid level in ginkgo and birch leaves during autumn yellowing
(Taylor & Francis Ltd, Abingdon, 2003)
Characterization of NAD-dependent malate dehydrogenases from spinach leaves
(Springer Wien, Wien, 2008)
Spinach leaves were used to extract isoforms of NAD-dependent malate dehydrogenase (NAD-MDH) (EC 1.1.1.37), either soluble or bound to microsomal, plasma, or chloroplast envelope membranes. All fractions were subjected to ...
Antioxidant Properties of Phenolics in Castanea sativa Mill. Extracts
(University of Zagreb, 2009)
Using electron paramagnetic resonance (EPR) spectroscopy, antioxidant properties of chestnut extracts have been investigated as a source of phenolic compounds. In addition to their high antioxidant activities against ...
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 ...
A PD simulation‑informed prediction of penetration depth of rigid rods through materials susceptible to microcracking
(Springer Nature, 2022)
The present investigation relies upon an
alternative approach to estimate the penetration depth
of rigid projectiles into quasibrittle materials that utilizes
simulation-informed modeling of penetration
resistance. ...
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 ...
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 ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Elsevier Science Sa, Lausanne, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
Mechanisms of detoxification of high copper concentrations by the microalga Chlorella sorokiniana
(Portland Press Ltd, London, 2020)
Microalgae have evolved mechanisms to respond to changes in copper ion availability, which are very important for normal cellular function, to tolerate metal pollution of aquatic ecosystems, and for modulation of copper ...
