One more general method for solving Oseen's equations
(Springer Wien, Wien, 1991)
In this paper we have proposed a new method for solving the Oseen's equations. It has been testified in the case of the normal flow around the cylinder for the Re number being much smaller than 1. The step forward was to ...
Determination of new ASOG-H parameters of CyCH, furfural and DMSO groups
(Serbian Chemical Society, Belgrade, 1996)
New interaction parameters for the groups CYCH(1)-furfural(2) and CyCH(1)-DMSO(2) of the ASOG-H model were determined, for 293.15 K-323.15 K and 303.15 K-323.15K respectively. The values of the CyCH(1)-furfural(2) parameters ...
Formation mechanism, morphology and synthesis of alpha-Al2O3, mullite and cordierite particles obtained by the ultrasonic spray pyrolysis
(Trans Tech Publications Ltd, Durnten-Zurich, 1996)
The present stage in our investigations of the synthesis of high-purity, submicrometer and spherical Al2O3, mullite and cordierte powders obtained by the ultrasonic spray pyrolysis is presented. The influence of precursors ...
Dynamic cell seeding of polymer scaffolds for cartilage tissue engineering
(Wiley, Hoboken, 1998)
Cell seeding of three-dimensional polymer scaffolds is the first step of the cultivation of engineered tissues in bioreactors. Seeding requirements of large scaffolds to make implants for potential clinical use include: ...
Condensation of 1,3-diketones with cyanoacetamide: 4,6-disubstituted-3-cyano-2-pyridones
(Serbian Chemical Society, Belgrade, 1998)
Elimination of vanadium and arsenic from VKCs catalysts
(Marcel Dekker Inc, New York, 1997)
Vanadium and arsenic eliminations from an alkaline leaching solution of spent VKCs catalysts were studied. To this end, several commercial resins or polymers synthesized in the laboratory were evaluated in a solid-liquid ...
Kinetics of lipase-catalyzed hydrolysis of palm oil in lecithin/izooctane reversed micellles
(Springer, New York, 1998)
Candida rugosa lipase has been used to investigate the hydrolysis of palm oil in a lecithin/isooctane reversed micellar system. The reaction obeys Michaelis-Menten kinetics for the initial conditions. Kinetic parameters ...
Stress state effect on dynamic strain aging and surface markings during stretching of AlMg7 alloy sheet
(Trans Tech Publications Ltd., 1998)
Stress state effect on dynamic strain aging (DSA) and the related surface appearance was analyzed in uniaxial and biaxial room temperature stretching of AlMg7 alloy sheet. In uniaxial tension the serrated yielding was found ...
Temperature dependent oxygen electrochemistry on platinum low index single crystal surfaces in acid solutions
(Natl Research Council Canada, Ottawa, 1997)
Using the rotating ring-disk technique (RRDPt(hkl)E), the oxygen-reduction reaction (ORR) was studied in sulfuric acid solution over the temperature range 298-333 K. At the same temperature, the exchange current density ...
Size distribution of ultrafine spherical ceramic powders obtained by ultrasonic spray pyrolysis
(Trans Tech Publications Ltd., 1997)
Comparative analysis of experimentally determined particle size distribution and theoretically calculated aerosole drop size distribution (obtained on the basis of 3D model of spherical / elliptical waves generated by the ...
