The flow of Newtonian and drag-reducing fluids around sphere
(Serbian Chemical Society, Belgrade, 1996)
The flow around a sphere placed coaxially in a cylindrical tube, the separation of the boundary layer and the wake shedding phenomena are investigated. The results of the simultaneous determination of the drag coefficients ...
31 P MAS NMR investigation of some microporous zincophosphates
(Serbian Chemical Society, Belgrade, 1996)
High field magic-angle spinning (MAS) 31 P-NMR investigations of novel porous zincophosphates and their cobalt-containing derivatives confirm the framework structure of alternating Zn(Co)O 4 and PO 4 tetrahedra. The MAS ...
Some aspects of the quantitative analysis of cyclic nucleotides by fast-atom bombardment mass spectrometry
(Serbian Chemical Society, Belgrade, 1996)
The possibilities of the quantitative analysis of cyclic nucleotides by fast-atom bombardment are examined. Aspects such as the amount of matrix, the formation of protonatcd ion species and the presence of more than one ...
Nondispersive solvent extraction-stripping of phenol in a hollow fiber-in-fiber membrane contactor
(Serbian Chemical Society, Belgrade, 1996)
Phenol extraction from aqueous solution and its simultaneous concentration into caustic stripping solution using a hollow fiber-in-fiber type membrane contactor was investigated. The phenol separation rate using sunflower ...
Apparent energy of activation for hot working of vanadium microalloyed steel
(Serbian Chemical Society, Belgrade, 1996)
Two-stage linear In [sinh(ασca)] vs.1/T plots, based on isothermal continuous and anisothermal multipass torsion curves, indicate the double Q HW behaviour of a V-steel. Above T nr , Q HW is independent of all variables ...
Low temperature processes during the synthesis of lanthanum lead borosilicate glasses
(Serbian Chemical Society, Belgrade, 1997)
Low temperature processes during the synthesis of PbO-B 2 O 3 -SiO 2 -La 2 O 3 glasses were studied by thermal analysis of the batch mixture of glasses and X-ray powder diffraction analysis of samples that crystallized ...
The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions
(Serbian Chemical Society, Belgrade, 1997)
The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions was studied. The lead leaching rates were measured using an agitated vessel at atmospheric pressure. The effects of the MgCl2 ...
Cubic equation of state models for liquid excess heat capacity calculations. II. Applicability of the PRSV-SR and PRSV-HVOS models to complex binary mixtures
(Serbian Chemical Society, Belgrade, 1998)
Binary liquid excess heat capacities C-p(E) for various kinds of complex binary systems measured by Conti and coworkers are well represented by the PRSV EOS modified van der Waals one fluid mixing rule proposed by ...
Condensation of 1,3-diketones with cyanoacetamide: 4,6-disubstituted-3-cyano-2-pyridones
(Serbian Chemical Society, Belgrade, 1998)
Kinetics of the reaction of 5-substituted orotic acids with diazodiphenylmethane / Kinetika reakcije 5-supstituisanih orotinskih kiselina sa dizaodifenilmetanom
(Serbian Chemical Society, Belgrade, 2004)
Rate konstants for the reaction of eight 5-substituted orotic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) were determined at 30 ºC by the known spectrophotometricmethod. The determined rate constants ...
