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 ...
Small structural changes of pentacyclic lupane type triterpenoid derivatives lead to significant differences in their anticancer properties
(Elsevier, 2010)
In the present investigations five new derivatives of betulinic and betulonic acid were synthesized and the effect of this structural variations on anticancer activity was studied and discussed. The antiproliferative ...
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 ...
Effect of mechanical-chemical activation of flotation tailings on removal the useful components / Uticaj mehano-hemijske aktivacije flotacijske jalovine na stepen izdvajanja korisnih komponenti
(Rudarski radovi, Bor, 2010)
The presented results refer to the investigation of effect the mechanical-chemical activation of flotation tailings on copper, iron and sulfur leaching degree in the sulfuric-chloride solution with the addition of H2O2 as ...
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 ...
Synthesis and Structure of New 5-(Arylidene)-3-(4-methylbenzoyl)thiazolidine-2,4-diones
(Wiley-Blackwell Publishing, Inc, Malden, 2010)
The derivatives of 5-substituted-2,4-thiazolidinedione have a broad spectrum of biological activities. In this article, new 5-(arylidene)-3-(4-methylbenzoyl)thiayolidine-2,4-diones 3a-k, with arylidene groups such as ...
Purification and characterisation of Saccharomyces cerevisiae external invertase isoforms
(Elsevier Sci Ltd, Oxford, 2010)
Four external invertase isoforms (EINV1, EINV2, EINV3 and EINV4) from Saccharomyces cerevisiae were highly purified by isoelectric precipitation, ethanol precipitation, ion-exchange on QAE-Sephadex and gel filtration using ...
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, ...
The influence of pH on removal of H2S and natural organic matter by anion resin
(Desalination Publ, Hopkinton, 2010)
A number of experiments with "specific"ground water from the Pannonian Plains (the Republic of Serbia) were conducted in order to define a technological process for drinking water treatment. The "specificity"of this raw ...
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 ...
