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 ...
Liver, gills, and skin histopathology and heavy metal content of the Danube sterlet (acipenser ruthenus linnaeus, 1758)
(Setac Press, Pensacola, 2010)
The sterlet (Acipenser ruthenus L.) is a bottom-feeding fish species with a direct exposure to contaminants from water and sediments. Although heavy metal pollution is believed to be one of the main threats to the sterlet ...
Application of superabsorbent polymers in the production of scotch pine (pinus sylvestris l.) And Austrian pine (pinus nigra arn.) Seedlings
(Parlar Scientific Publications (P S P), Freising, 2010)
The effect of superabsorbent polymers on Scotch pine (Pinus sylvestris L.) and Austrian pine (Pinus nigra Am.) seed germination and the development of 1-year-old- and 2-year-old seedlings were analyzed. The study results ...
Impedance Response and Dielectric Relaxation in Liquid-Phase Sintered Zn2SnO4-SnO2 Ceramics
(Springer, New York, 2010)
Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn2SnO4-SnO2 ceramics. The measurements were performed over a wide ...
The content of antioxidants in sunflower seed and kernel
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
The primary objective of this research was to determine differences among investigated sunflower genotypes and whether the analysed hybrids could be sources of phenols and tocopherols important for storage stability of ...
Optical properties of PbTe doped with Nd
(Springer, New York, 2010)
Single crystals of lead telluride doped with Nd were synthesized using the Bridgeman method. Room temperature far infrared reflectivity spectra were measured for PbTe samples with Nd content in the range 0.2-0.9 at.%. ...
RF equivalent circuit modeling of surface mounted components for PCB applications
(Emerald Group Publishing Ltd, Bingley, 2010)
Purpose - The appropriate selection of a testing method largely determines the accuracy of a measurement. Parasitic effects associated with test fixture demand a significant consideration in a measurement. The purpose of ...
