Supercritical carbon dioxide essential oil extraction of Lamiaceae family species: Mathematical modelling on the micro-scale and process optimization
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
In this paper the essential oil supercritical carbon dioxide extraction from leaves of Lamiaceae family species was studied. Recent investigations of Lamiaceae family essential oil storage have shown that most of the oil ...
Experimental design approach in the synthesis of hydroxyapatite by neutralization method
(Elsevier, Amsterdam, 2005)
Physicochemical properties of hydroxyapatite (HAP) synthesized by neutralization method are heavily dependent on the process variables. A Plackett-Burman two-level experimental design was therefore, chosen to screen a large ...
The influence of titanium and cerium on microstructure and properties of Fe-C-Cr-Nb alloys / Uticaj titana i cerijuma na mikrostrukturu i svojstva Fe-C-Cr-Nb legura
(Savez inženjera metalurgije Srbije, Beograd, 2005)
In this paper, the influence of titanium and cerium on the microstructure and properties of Fe-C-Cr-Nb alloys are examined, in both as-cast and heat treated state. These elements affect the crystallisation process of ...
Scaling of network segment dimensions in hyperelastic composites
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The change in elastomer tensile moduli, as formulated in the Gaussian statistical theory of rubber elasticity, with deformation, is considered both experimentally and theoretically. Gum elastomers of different structures ...
Hydrogels based on 2-hydroxyethyl methacrylate obtained by gamma irradiation
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Hydrogels based on 2-hydroxyethyl methacrylate and different types of poly(alkylene glycol) acrylates and methacrylates, with a small percent of itaconic acid, have been prepared by solution copolymerization using gamma ...
NMR analysis of (1S, 1aR, 6aR)-2’, 3’, 6, 6a-tetrahydrospiro cycloprop a indene-1(1aH), 1’- 1H indene / NMR analiza (1S,1aR,6aR)-2’,3’,6,6a-tetrahidro-spiro[cikloprop[a]inden-1(1ah),1’-[ 1h]indena]
(Serbian Chemical Society, Belgrade, 2005)
The aldol condensation product of 1H-indan-1-one, (2E)-2-(2,3-dihydro-1H-in den-1-ylidene)-2,3-dihydro-1H-inden-1-one, subjected to Huang–Minlon reduction conditions was shown, via 1D and 2D NMR analysis, to be a mixture ...
Prediction of peak-to-background ratio in gamma-ray spectrometry using simplex optimized artificial neural network
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
An artificial neural network (ANN) model was used for the prediction of peak-to-background ratio (PBR) as a function of measurement time in gamma-ray spectrometry. In order to make the ANN model with good predictive power, ...
Speedup of Clos packet switches that provide delay guarantees
(IEEE, New York, 2005)
A multihop Clos fabric may provide the terabit capacity by using the smaller switching elements (SE). When the traffic load is balanced over the switches in a middle stage, all the traffic would get through the fabric, as ...
Enhanced Cell-ID+TA GSM positioning technique
(IEEE, New York, 2005)
The majority of existing GSM positioning techniques can be described as either costly or with limited performance. Basic GSM positioning techniques Cell-ID and Cell-ID+TA can be upgraded to decrease positioning error. We ...
