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 ...
Land degradation on barren hills: A case study in northeast Vietnam
(Springer, New York, 2008)
The term "barren hills" has been a keyword for land degradation in the uplands of Vietnam for over a decade. Nevertheless, the "barren" land is still not adequately ecologically characterized. In this work, we analyze land ...
Far infrared reflectance of sintered Zn2TiO4
(Springer, New York, 2008)
Zinc-titanate ceramics were obtained by initial mechanical activation in a high-energy planetary mill for 15 min followed by sintering at temperatures 900-1100 degrees C for 2 h. Room temperature far infrared reflectivity ...
Star-shaped oligobenzoates: Non-conventional mesogens forming columnar helical mesophases
(Wiley-V C H Verlag Gmbh, Weinheim, 2008)
Star-shaped mesogens with a phloroglucinol or a trimesic acid core and oligobenzoate arms with up to five repeating units have been synthesised. non-conventional mesogens form various columnar mesophases over a broad ...
Peroxidase activity and phenolic compounds content in maize root and leaf apoplast, and their association with growth
(Elsevier Ireland Ltd, Clare, 2008)
Apoplastic fluid originated from maize (Zea mays L) leaf and root growing and non-growing regions were analyzed for peroxidase (POD) activities and phenols content. The samples were obtained by two different methods, as ...
Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
Pt/C doped by MoOx as the electrocatalyst for oxygen reduction and methanol oxidation
(Elsevier Science Bv, Amsterdam, 2008)
The oxidation of methanol and reduction of oxygen were studied on MoOx-Pt/C nano-catalysts prepared by the polyole method combined by MoOx post-deposition. The catalysts were characterized by TEM and EDX. The presented ...
Far infrared properties of PbTe doped with Bismuth
(Springer, New York, 2008)
Far infrared reflectivity spectra of single crystal PbTe doped with Bi were measured and numerically analyzed using a fitting procedure based on a modified plasmon-phonon interaction model with two additional oscillators ...
Induction of peroxidases and superoxide dismutases in transformed embryogenic calli of alfalfa (Medicago sativa L.)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
Peroxidase (POD) and superoxide dismutase (SOD) enzyme activities were analyzed in non-regenerative transformed embryogenic lines of alfalfa (Medicago sativa L.) carrying wound-inducible oryzacystatin I (OC-I), wound-inducible ...
Electromechanical Switch Based on Mo6S6 Nanowires
(Amer Chemical Soc, Washington, 2008)
We investigate the structural, electronic, and transport properties of mechanically deformed Mo6S6 nanowires using a density-functional based tight binding method extended with a Green's functions formalism. We present two ...
