Cloning of Saccharomyces cerevisiae MnSOD in Escherichia coli
(Balkan society for microbiologyTurkish micorbiological society, 2003)
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 ...
The critical apparent density for the free flow of copper powder / Kritična nasipna masa za tečenje praha bakra
(Serbian Chemical Society, 2003)
A method for the determination of the critical apparent density, which permits the free flow of electrodeposited copper powder is discussed. It was found that powders the apparent density of which were larger than 2.3 g/cm3 ...
The current efficiency during the cathodic period of reversing current in copper powder deposition and the overall current efficiency / Iskorišćenje struje za vreme katodnog perioda reversne struje pri taloženju bakarnog praha i ukupno iskorišćenje struje
(Serbian Chemical Society, 2003)
The current efficiency during the cathodic period of reversing current in copper powder deposition was determined by measuring the quantity of hydrogen evolved. The diagrams from which the instantaneous and average current ...
Absorption in a three-phase fluidized bed II: Mass transfer investigations / Apsorpcija u koloni sa pokretnim punjenjem II - ispitivanja karakteristika prenosa Mase
(Association of Chemical Engineers of Serbia, 2003)
The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration ...
Comparative electrochemical study of some cobalt(III) and cobalt(II) complexes with azamacrocyles and β-diketonato ligands / Komparativno elektrohemijsko ispitivanje nekih kobalt(III)i kobalt(II) kompleksa sa azamakrocikličnim i β-diketonato ligandima
(Serbian Chemical Society, 2003)
The electrochemical properties of eight mixed-ligand cobalt(III) and co balt(II) complexes of the general formulas [CoIII(Rac)cyclam (ClO4)2 (1)–(4) and [Co2II(Rac)tpmc](ClO4)3 (5)–(8) were studied. The substances were ...
Acid-catalyzed and photolytic reactivity of some unsaturated B-nor-5, 10-secosteroidal ketones / Kiselo-katalizovana i fotolitička reaktivnost nekih nezasićenih B-nor-5,10-sekosteroidnih ketona
(Serbian Chemical Society, 2003)
The acid-catalyzed reaction of (Z)- and (E)-B-nor-5,10-seco-ketones 2 and 3 resulted in an intramolecular cyclization to give the 5-hydroxy-A-nor-1β,5β-10(19)-methylidene derivative 8, the 5β-hydroxy-A-nor-1(10)-unsaturated ...
Oil pollutants in alluvial sediments - influence of the intensity of contact with ground waters on the effect of microorganisms / Naftni zagađivači u aluvijalnim sedimentima - uticaj intenziteta kontakta sa podzemnim vodama na dejstvo mikroorganizama
(Serbian Chemical Soc, Belgrade, 2003)
The influence of the intensity of interaction between oil pollutants and ground waters in alluvial sediments on the effect of microbial activity was investigated in this work. The study was based on a comparison of detailed ...
Antimalarial, antimycobacterial and antiproliferative activity of phenyl substituted mixed tetraoxanes / Antimalarijska, antimikobakterijska i antiproliferativna aktivnost fenil-supstituisanih tetraoksana
(Serbian Chemical Society, 2003)
Mixed tetraoxanes of the 4"-phenyl-substituted cyclohexyl-spirotetraoxacyclohexyl- spirocholate series have been prepared and evaluated as possible antimalarials, antiproliferatives and antimycobacterials. The activity of ...
