Application of nonlinear frequency response to investigation of membrane transport
(Taylor & Francis Inc, Philadelphia, 2006)
The concept of higher order frequency response functions, used for investigation of weekly nonlinear systems by frequency response techniques, is applied to investigation of membrane systems. Isothermal permeation of single ...
Classification of soil samples according to their geographic origin using gamma-ray spectrometry and principal component analysis
(Elsevier Sci Ltd, Oxford, 2006)
A principal component analysis (PCA) was used for classification of soil samples from different locations in Serbia and Montenegro. Based on activities of radionuclides (Ra-226, U-238, U-235, K-40, Cs-134, Cs-131, Th-232 ...
Optimization of the electrostatic droplet generation process for controlled microbead production: Single nozzle system / Optimizacija elektrostatičkog generisanja čestica u cilju kontrolisanja njihovih mikronskih veličina - sistem sa jednom mlaznicom
(Association of the Chemical Engineers of Serbia, 2006)
The aim of this study was to optimize the electrostatic extrusion process for producing small, spherical and uniform microbeads with different fluid viscosities by varying the operating parameters in very wide ranges. ...
Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
Simultaneous correlation of VLE, He and Cpe of some diether + n-alkane systems by the Kohler polynomial / Simultano korelisanje VLE, He i Cpe podataka dietar + n-alkan sistema pomoću Kohlerovog polinoma
(Serbian Chemical Society, Belgrade, 2006)
The simultaneous correlation of VLE and excess properties (HE, cPE) for diether + n-alkane systems was performed in our previous paper by the cubic equation of state which incorporates the activity coefficient model ...
Correlation analysis of IR, H-1 NMR and UV spectral data of alkyl and aryl 4,6-disubstituted-3-cyano-2-pyridones. Part I
(Arkat Usa Inc, Gainesville, 2006)
Spectral characteristics of the two series of previously synthesized and identified 4,6-disubstituted- 3-cyano-2-pyridones were determined, and corresponding H-1 NMR chemical shifts and IR and UV frequencies were correlated ...
New analytical HFET I-V characteristics model
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
In this paper the new analytical model of current - voltage characteristics of a Heterostructure Field Effect Transistor (HFET), is proposed. The model is relatively simple, and at the same time, it describes complex HFET ...
Influence of electrode materials and the manner of electrode surface processing on gas-filled surge arresters relevant characteristics
(2006 25th International Conference on Microelectronics, MIEL 2006, 2006)
The aim of this paper is to present the electrode effects as approach for the improvement of gas filled surge arresters (GFSA) protective characteristics in the most optimal way. We examined the influence of the electrode ...
The plane-to-cellular-to-dendrite transition of the shape of the crystallization front during the crystallization of Al-Cu alloys / Prelaz sa ravnog fronta kristalizacije na ćelijski i dendritni rast kod kristalizacije legure Al-Cu
(Serbian Chemical Society, Belgrade, 2006)
The evolution of the crystallization front from a planar to a dendritic one as a function of the G L/(Rc 0) parameter was investigated during the crystallization of Al-Cu alloys by the vertical Bridgman method. Six series ...
Silver in medieval Serbia / Srebro u srednjovekovnoj Srbiji
(Savez inženjera i tehničara Srbije, Beograd, 2006)
In Serbia there were several polimetal ores deposits from which silver was exploited during ancient times and middle ages. Large silver production in middle ages, during Nemanjić dynasty, contributed to development and ...
