Evaluation of heavy metal contamination in sediments using the method of total digestion and determination of the binding forms-Tisa River Basin, Serbia
(Taylor and Francis Inc., 2010)
This paper describes an approach for the evaluation of metal contamination in sediment, using the determination of binding forms of elements (sequential extraction method), the total element content (digestion method), as ...
Water-soluble main ions in precipitation over the southeastern Adriatic region: chemical composition and long-range transport
(Springer Heidelberg, Heidelberg, 2010)
Precipitation samples collected from 1995 to 2000 at meteorological station in the eastern outskirts of Herceg Novi (Montenegro) were analysed on Na(+), K(+), Mg(2+), Ca(2+), Cl(-), SO(4) (2-), NO(3) (-) and NH(4) (+). ...
Design of symmetric planar fishnet metamaterials for optical wavelength range
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
In this work we analyze fishnet-type optical metamaterials with full electromagnetic symmetry, fabricated in an ultrathin, freestanding film (self-supported nanomembrane). We utilized the finite element method to simulate ...
Classification of stacking interaction geometries of terpyridyl square-planar complexes in crystal structures
(Royal Soc Chemistry, Cambridge, 2010)
Stacking interactions of terpyridyl square-planar complexes in crystal structures were studied analyzing data from the Cambridge Structural Database. In most of the crystal structures, two terpyridyl complexes were oriented ...
EBG band-stop filter with suppression of 3 spurious stop-bands
(Final Program and Book of Abstracts - iWAT 2010: 2010 International Workshop on Antenna Technology:, 2010)
Based on the well known theory of infinite periodic structures, analytical theory of EBG (electromagnetic band gap) cells suppressing 3 higher (spurious) stop-bands is developed. Using such cells in a cascade the ...
Quantification of the lift height for magnetic force microscopy using 3D surface parameters
(Elsevier, 2010)
In this work, the quantitative conditions for the lift height for imaging of the magnetic field using magnetic force microscopy (MFM) were optimized. A thin cobalt film deposited on a monocrystalline silicon (1 0 0) substrate ...
Study of flow and pressure field in microchannels with various cross-section areas
(Elsevier, 2010)
In this work a micro-flow sensor integrated in the bottom surface of a rectangular microchannel is used in order to evaluate simultaneously both the flow velocity and the pressure in various micro-flow conditions. In this ...
Purification and properties of trypsin-like enzyme from the midgut of morimus funereus (coleoptera, cerambycidae) larvae
(Wiley-Blackwell, Hoboken, 2010)
Trypsin-like enzyme (TLE) from the anterior midgut of Morimus funereus larvae was purified by anion exchange chromatography and gel filtration chromatography and characterized. Specific TLE activity was increased 322-fold ...
A trapezoidal microstrip bandstop filter with efficient suppression of undesired stopbands
(National Institute of Optoelectronics, 2010)
A new bandstop filter implemented as a cascade of trapezoidally shaped cells is presented. The proposed bandstop filter suppresses many undesired stopbands at higher frequencies. The cell design is specified by two variables ...
Effect of parameters of square-wave pulsating current on copper electrodeposition in the hydrogen co-deposition range
(Elsevier Science Inc, New York, 2010)
Copper electrodeposition processes in the hydrogen co-deposition range by the pulsating current (PC) regime were examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
