Antimalarial and antiproliferative evaluation of bis-steroidal tetraoxanes
(Elsevier, 2003)
Several cis and trans bis-steroidal 1,2,4,5-tetraoxanes possessing amide terminus were synthesised and evaluated as antimalarials and antiproliferatives. The compounds exhibited submicromolar antimalarial activity against ...
A new class of electromagnetically coupled printed antenna arrays
(IEEE Computer Society, 2003)
A new class of electromagnetically coupled microwave printed antenna arrays using three coplanar strip-TCS (CPW with finite narrow ground strips) is reported. Two versions of this antenna array are introduced. (1) Antenna ...
A new type of slow-wave PBG microstrip ring resonator
(IEEE Computer Society, 2003)
A new type of microstrip ring resonator is introduced. In order to minimized dimensions the ring resonator is constructed like a PBG structure. The central frequency is 50% lower than in the conventional case. Additional ...
Methanol electrooxidation on supported Pt and Pt/Ru catalysts in alkaline solution / Oksidacija metanola na Pt i Pt/Ru nanokatalizatorima u alkalnoj sredini
(Tehnika - Novi materijali, 2003)
The kinetic of methanol oxidation on 47.5 wt% Pt and 54 wt% Pt/Ru catalysts supported on high surface area carbon are measured in 0.1 M NaOH at 295 K and 333 K. The catalysts used were characterized by using TEM and XRD ...
Effect of temperature on the methanol oxidation at supported Pt and PtRu catalysts in alkaline solution
(Elsevier, 2003)
The effect of temperature on the kinetics of methanol oxidation on supported 47.5 wt% Pt, 54 and 33.5 wt% Pt/Ru catalysts was studied in 0.1 M NaOH at 295, 313 and 333 K using thin-film rotating disk electrode (RDE) method. ...
Light modulation utilizing photonic crystal-based photoelastic elements with dual built-in defect
(IEEE Computer Society, 2003)
In this paper we analyze optical modulation by stress-sensitive active elements based on photonic crystals utilizing photoelasticity effects. Our approach is to utilize thin film sensitive elements with photonic bandgap ...
Cloning of Saccharomyces cerevisiae MnSOD in Escherichia coli
(Balkan society for microbiologyTurkish micorbiological society, 2003)
Determination of all pK(a) values of some di- and tri-carboxylic unsaturated and epoxy acids and their polylinear correlation with the carboxylic group atomic charges
(Scientific Reviews Ltd., 2003)
For a series of seven unsaturated and seven epoxy di- and tricarboxylic acids, pK(a)(a) values were determined potentiometrically in aqueous media at 25 degreesC and an ionic strength of 0.1 M (NaCl). The thermodynamic ...
Electrochemical deposition of Ni–W alloys from ammonia–citrate electrolyte
(Elsevier, 2003)
Ammonia-citrate electrolyte is one of the solutions that are used in practice for electroplating Ni-W alloys. In this contribution, a systematic effort was made to clarify some controversies about the mechanism of 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 ...
