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 ...
Far infrared properties of sintered Pb0.9Sn0.1Te doped with palladium
(Springer, New York, 2009)
Far infrared reflectivity spectra of sintered Pb0.9Sn0.1Te doped with 0.2 and 2 at.% Pd are measured. The experimental results are analyzed using a fitting procedure based on a modified plasmon-phonon interaction model. ...
Far infrared study of some rare earth impurities crystals of Pb1-xSnx alloys
(National Institute of Optoelectronics, 2009)
Single crystal samples of Pb0.9Sn0.1Te doped with Yb, Sm or Gd were produced using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for highly polished samples with various impurity ...
Transport properties of MoS2 nanoribbons: edge priority
(Springer, New York, 2012)
We report about results from density functional based calculations on structural, electronic and transport properties of one-dimensional MoS2 nanoribbons with different widths and passivation of their edges. The edge ...
A strain of phytoplasma related to 16SrII group in Picris hieracioides L. in Serbia
(Alma Mater Studiorum, Univ Bologna, Bologna, 2011)
During epidemiological survey for phytoplasmas in association with agricultural crops in Serbia, a new species of common weed has been detected to harbor phytoplasmas in Serbia. In 2010, a total of 38 samples of Picris ...
Deconvolution of lignin fluorescence spectra: A contribution to the comparative structural studies of lignins
(Maik Nauka/Interperiodica/Springer, New York, 2007)
In this work, we deconvoluted the fluorescence spectra of lignin and a lignin model compound using a combination of one symmetric ( Gaussian) and the most appropriate number of asymmetric (Log-normal) models. We aimed to ...
Microstructural characterization of mechanicallyactivated ZnO powders
(Wiley, Hoboken, 2008)
In this paper, changes of microstructural characteristics of disperse systems during mechanical activation of zinc oxide (ZnO) have been investigated. ZnO powder was activated by grinding in a planetary ball mill in a ...
Fatty Acids of Some Moss Species from Germany
(Asian Journal Of Chemistry, Sahibabad, 2011)
The fatty acid composition of three mosses collected in Germany was preliminary analyzed by gas chromatography (GC-FID) and gas I chromatography-mass spectrometry (GC-MS) for the first time. It was found that Hypnum ...
Comparative research of accumulation of heavy metals in woody plants and herbs
(Parlar Scientific Publications (P S P), Freising, 2011)
Vascular plants can precisely indicate the presence and intensity of different pollutants (heavy metals, chemical substances etc.) in air and soil in natural ecosystems as well as in the urban environments. The accumulation ...
Biological activities of phenolic compounds and ethanolic extract of Halacsya sendtneri (Boiss) Dorfler
(De Gruyter Poland Sp Z O O, Warsaw, 2012)
The objective of this study was to evaluate the efficacy of the ethanolic extract of endemic plant Halacsya sendtneri in inhibiting the growing of the test fungi and bacteria as well as to determine its genotoxic potential ...
