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) (+). ...
Synthesis, characterization and in vitro cytotoxicity studies of platinum(IV) complexes with thiouracil ligands
(Elsevier, 2010)
Reactions of [PtMe3(bpy)(Me2CO)][BF4] (2) with the thionucleobases 2-thiouracil (s2Ura), 4-thiouracil (s 4Ura) and 2,4-dithiouracil (s2s4Ura) resulted in the formation of complexes of the type [PtMe3 (bPy)(L-κS)] [BF4] (L= ...
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 ...
Trace elements as tracers of environmental pollution in the canal sediments (alluvial formation of the Danube River, Serbia)
(Springer, Dordrecht, 2010)
The purpose of this study was to examine the levels of trace elements and to discuss the origin and mobility of these contaminants in the canal sediments (alluvial formation of the Danube River). The most significant ...
Chemical surface composition of the polyethylene implanted by Ag+ ions studied by phase imaging atomic force microscopy
(Elsevier, 2010)
High density polyethylene (HDPE) has been modified by Ag+ ion implantation with the energy of 60 keV. The total amount of implanted silver ions was 1, 5 and 12 x 10(15) ions/cm(2). The surface topography was observed by ...
The electrochemical reduction of trinitrotoluene on a platinum wire modified by chemisorbed acetonitrile
(Elsevier, 2010)
The electrochemical reduction of 2,4,6-trinitrotoluene (TNT) was investigated by cyclic voltammetry on a platinum electrode in aqueous sodium chloride solutions with acetonitrile containing different concentrations of TNT. ...
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 ...

(Wiley-Blackwell, Malden, 2010)
The simple PVC-based membrane containing N',N',N '',N '''-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) as an ionophore and dibutyl phthalate as a plasticizer, directly coated on a glassy carbon electrode ...
Protein subunit interfaces: a statistical analysis of hot spots in Sm proteins
(Springer, New York, 2010)
The distinguishing property of Sm protein associations is very high stability. In order to understand this property, we analyzed the interfaces and compared the properties of Sm protein interfaces with those of a test set, ...
