Antioxidative system in maize roots as affected by osmotic stress and different nitrogen sources
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2010)
The activities of antioxidative enzymes and contents of proline and total phenolics were assayed in roots of two maize (Zea mays L.) genotypes grown in a medium containing nitrate (NO3 (-)) or both nitrogen forms, nitrate ...
Parameters Extraction of Ferrite EMI Suppressors for PCB Applications Using Microstrip Test Fixture
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2010)
The goal of this work was to investigate the behavior of a ferrite electromagnetic interference (EMI) suppressor when placed in a real surrounding. Electrical parameter measurements of the same EMI suppressor can differ ...
Optical far infrared properties of FeS2
(National Institute of Optoelectronics, 2010)
In this paper are presented the far-infrared reflectivity spectra for a cleaved FeS2 sample measured at roam temperature and at 77 K.
Nepetalactone content in shoot cultures of three endemic Nepeta species and the evaluation of their antimicrobial activity
(Elsevier, Amsterdam, 2010)
Rapid micropropagation of Nepeta rtanjensis, N. sibirica and N. nervosa was performed. Qualitative and quantitative nepetalactone content in methanol extracts of in vitro grown plants was analysed by reverse-phase HPLC ...
Characterization of ferrite surface mount bead using S-parameters
(SIISY 2010 - 8th IEEE International Symposium on Intelligent Systems and Informatics, 2010)
In this paper, characterization of ferrite surface mount bead based on S-parameters measurement, using vector network analyzer E5071B and specially developed PCB test fixture, are presented. The validation of characterization ...
Effect of chemisorbed CO on MoOx-Pt/C electrode on the kinetics of hydrogen oxidation reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The influence of poisoning of MoOx-Pt catalyst by CO on the kinetics of H-2 oxidation reaction (HOR) at MoOx-Pt electrode in 0 5 mol dm(-3) HClO4 saturated with H-2 containing 100 ppm CO was examined on rotating disc ...
The potential physiological implications of polygalacturonic acid-mediated production of superoxide
(Landes Bioscience, 2010)
PGA/OGA/PF represent apoplastic signaling molecules implicated in the control of gene expression and the activity of enzymes involved in defense regulation. However, the underlying mechanisms behind such processes are ...
Zinc-induced oxidative stress in Verbascum thapsus is caused by an accumulation of reactive oxygen species and quinhydrone in the cell wall
(Wiley, Hoboken, 2010)
Oxidative stress is one aspect of metal toxicity. Zinc, although unable to perform univalent oxido-reduction reactions, can induce the oxidative damage of cellular components and alter antioxidative systems. Verbascum ...
Sintered strontium hexaferrite shaped by injection moulding in unidirectional magnetic and electromagnetic field
(European Powder Metallurgy Association (EPMA), 2010)
Strontium hexaferrite permanent magnets were produced by powder injection molding (PIM). The feedstock for powder injection molding was prepared by mixing strontium hexaferrite powder with a "Solvent system" organic binder. ...
Infrared and Raman spectroscopy study of antimony doped barium titanate prepared from organometallic complex
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Pure and antimony doped barium titanate powders were prepared by polymeric precursors method through Pechini process, which was carried out as a three-stage process from organometallic complex. Obtained powder was pressed ...
