Degradation of transformer oil on the basis of polychlorinated bifenyls without degrading the existing quality of the environment / Degradacija transformatorskog ulja na bazi polihlorovanih bifenila bez narušavanja postojećeg kvaliteta životne sredine
(Elektroprivreda, 2003)
This paper deals with results of laboratory experiments referring to transformer oil chemical degradation on the basis of polychlorinated bifenyls, results referring to rinsing of transformer insulation material, as well ...
The roughness analysis of metal coatings by STM technique part III: Analysis of copper coatings electrodeposited with thiourea as brightening additive / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije III deo - analiza prevlaka bakra istaloženih sa tioureom kao aditivom za sjaj
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work is given the analysis of roughness of copper coatings electrodeposited from a sulfate bath in the presence of thiourea, by methodology which is described in part I of this work. It was shown that the ...
Hyperatomarin, an antibacterial prenylated phloroglucinol from Hypericum atomarium ssp degenii
(American Chemical Society (ACS), 2003)
As shown by quantitative 1H NMR measurements, a lipophilic extract of the aerial parts of Hypericum atomarium ssp. degenii contained a high percentage (3.1% per weight of dried plant material) of a prenylated phloroglucinol ...
Electrical Conductivity of Fullerene Derivatives
(Trans Tech Publications, Switzerland, 2003)
In this paper electrical conductivity of fullerene derivatives was investigated. Compared with pure fullerene (molecule C60), which is an insulator (10-12 Sm-1), the measured C60(OH)24 shows several order of magnitude ...
The roughness analysis of metal coatings by STM technique part IV: The relation between brightness and mechanisms of metal electrodeposition / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije IV deo - veza između sjaja i mehanizma elektrohemijskog taloženja metala
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work is given the analysis of roughness of copper coatings electrodepositedfrom a sulfate bath in the presence of modified polyglycol ether (Lutron H F 1), PEG 6000 and 3 - mercapto alkane sulfonate, by methodology ...
Electrochemically deposed Ni/W composite coatings obtained under constant and pulsating current regimes / Kompozitne Ni/WC prevlake dobijene elektrohemijskim taloženjem konstantnom i pulsirajućom strujom
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
The properties of composite coatings are dependent on properties of the base metal, as well as on properties of incorporating particles. The Ni / W composite coatings were obtained by electro deposition from commercially ...
Osmotic coefficient of the ZnCl2(aq) at T = 298.15 K
(Elsevier, 2003)
The osmotic coefficient of ZnCl2 (aq) has been measured at T = 298.15 K by the isopiestic method over the range of molalities from (0.4 to 2.4)mol·kg -1 with KCl(aq) as the reference solution. The available literature data ...
An electrochemical illustration of the mathematical modelling of chlorine impact and acidification in electrochemical tumour treatment and its application on an agar-agar gel system
(Elsevier, 2003)
Electrochemical treatment (EchT) of tumours, which is also known as electrochemical therapy, implies that tumour tissue is treated with a direct current through the use of electrodes. This was shown earlier when the major ...
A new class of electromagnetically coupled printed antenna arrays
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2003)
We report a new class of electromagnetically coupled microwave printed antenna arrays using three coplanar strip-TCS (CPW with finite narrow ground strips). Two versions of this antenna array are introduced. (1) Antenna ...
Further degradation product of hyperforin from Hypericum perforatum (St. John's Wort)
(Elsevier, 2003)
Repeated examination of the aerial parts of Hypericum Perfomtum yielded a new degradation product of hyperforin (1) namely deoxyfurohyperforin A (2), together with the previously identified furohyperforin (3), furoadhyperforin ...
