Mass transfer in vertical liquid-solids flow of coarse particles
(Powder Technology, 2009)
Wall-to-bed mass transfer in the hydraulic transport of spherical glass particles was studied. The experiments were performed by transporting spherical glass particles 1.20, 1.94 and 2.98 mm in diameter with water in a ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j D ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
Photocatalytic degradation of wastewater polluted by methyl-tertiary-butyl-ether using titanium-dioxide and doped titanium-dioxide
(Proceedings of the 4th Iasme/Wseas International Conference on Water Resources, Hydraulics and Hydro, 2009)
The subject of this research was utilization of concentrated solar radiation simulated with a sodium lamp SONT UV100, in lab condition, on removal of wastewater polluted by methyl-tertiary-butyl-ether (MTBE). The effects ...
Chemical composition and antimicrobial activity of essential oil of physocaulis nodosus (L.) W.D.J.Koch
(Journal of Essential Oil Research, 2009)
Aerial parts of Physocaulis nodosus (L.) W.D.J.Koch. (Apiaceae) collected on Hajla mountain possessed an essential oil in 0.62% yield (expressed in g per 100 g of dried plant material). The oil was analyzed by GC and GC/MS. ...
Temperature influence on the malonic acid decomposition in the Belousov-Zhabotinsky reaction

The kinetic investigations of the malonic acid decomposition (8.00 x 10(-3) mol dm(-3) a parts per thousand currency sign [CH(2)(COOH)(2)](0) a parts per thousand currency sign 4.30 x 10(-2) mol dm(-3)) in the Belousov-Zhabotinsky ...
Predictive modeling of the hypothalamic-pituitary-adrenal (HPA) function. dynamic systems theory approach by stoichiometric network analysis and quenching small amplitude oscillations
(International Journal of Nonlinear Sciences and Numerical Simulation, 2009)
Two methods for dynamic systems analysis, Stoichiometric Network Analysis (SNA) and Quenching of Small Amplitude Oscillations (QA), are used to study the behaviour of a vital biological system. Both methods use geometric ...
Review of our beneficiation of oil shale by bioprocessing on laboratory scale
(International Oil Shale Symposium, Tallin, Estonia, 8-11 June 2009, 2009)
It is estimated that reserves of oil shale in Serbia amounts to about 3 billion tons while the largest deposit (approx. 2/3 of total amount) for open-pit and underground exploitation is situated in the locality of Aleksinac ...
Study on fisetin-aluminium(III) interaction in aqueous buffered solutions by spectroscopy and molecular modeling
(Elsevier Science Inc, New York, 2009)
Spectroscopic (UV/visible and IR) and theoretical studies were used to assess relevant interaction of fisetin, a tetrahydroxylated flavone molecule, and trivalent aluminium in a wide range of buffered aqueous solutions. ...
Geochemical investigation and characterisation of Neogene sediments from Valjevo-Mionica Basin (Serbia)
(Springer, New York, 2009)
Sediments from the Valjevo-Mionica Basin of Neogene age were investigated in this study using different geochemical methods. The results of the inorganic part analyses suggest that during genesis of the sediments, the ...
Pyrolysis and Pt(IV)- and Ru(III)-ion catalyzed pyrolysis of asphaltenes in organic geochemical investigation of a biodegraded crude oil (Gaj, Serbia)
(Elsevier Sci Ltd, Oxford, 2009)
This paper is aimed at investigating the origin and geological history of the biodegraded Gaj (Serbia) crude oil, based on comparison of biomarkers, particularly alkylaromatics, in crude oil maltene fraction, with those ...
