Copolymer hydrogels based on N-isopropylacrylamide and itaconic acid
(Elsevier Sci Ltd, Oxford, 2006)
In this study, the swelling behaviour of copolymer hydrogels of N-isopropylacrylamide (NIPAM) and itaconic acid (IA) in response to temperature and pH value of the external media was studied. The equilibrium degree of ...
Effects of operating parameters on efficiency of cadmium and zinc removal by the complexation-filtration process
(Elsevier, Amsterdam, 2006)
A process for purifying wastewaters containing heavy and toxic metals such as cadmium and zinc by the complexation-filtration process was studied. From previous research, diethylaminoethyl cellulose (DEAE23) was selected ...
Swelling and drug release behavior of poly(2-hydroxyethyl methacrylate/itaconic acid) copolymeric hydrogels obtained by gamma irradiation / Bubrenje i kontrolisano otpuštanje aktivnih materija iz poli(2-hidroksietil metakrilat/itakonska kiselina) kopolimernih hidrogelova dobijenih gama ozračivanjem
(Savez inženjera i tehničara Srbije, Beograd, 2006)
The new copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were prepared by gamma irradiation, in order to examine the potential use of these hydrogels in controlled drug release ...
Problems and prospect of Al-Mg alloys application in marine constructions
(Savez inženjera metalurgije Srbije, Beograd, 2006)
The position of steel as the most widely used material in the shipbuilding industry originates from the superior mechanical properties and low manufacturing costs The increasing demands for lowering the weight of different ...
Supercritical carbon dioxide extraction of carrot fruit oil - Comparison with hydrodistillation and modelling
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
In this study the compositions of Carrot fruit (Daucus carrota, cultivar Chanteney) essential oil obtained by hydrodistillation and its extract obtained by supercritical carbon dioxide extraction at 313 K and 10 MPa were ...
Enhancement of the electrochemical reduction of oxygen at platinum by nickel underpotential deposition
(Springer, New York, 2006)
Polycrystalline Pt electrode was modified by underpotential deposition (upd) of nickel. The modification was performed by potential cycling in phosphate buffer pH 7. 0 containing NiSO4, in which hydrogen and nickel upd ...
Design, implementation and testing of the controller for the terabit packet switch
(IEEE, New York, 2006)
The sequential greedy scheduling (SGS) is a scalable algorithm that provides non-blocking in high-capacity packet switches. We implemented the SGS scheduler in the FPGA device, and examined its scalability and speed. Then, ...
Electrochemical deposition and corrosion stability of Zn-Co alloy coatings / Elektrohemijsko taloženje i koroziona stabilnost prevlaka Zn-Co legura
(Engineering Society for Corrosion, Belgrade, Serbia, 2006)
The influence of the type of the deposition solution, deposition current density and temperature of deposition solution on the phase structure and corrosion properties of Zn-Co alloys was examined. Alloys were deposited ...
Removal of heavy metal ions from water by complexation-assisted ultrafiltration
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Toxic heavy metals in air, soil and water are global problems that are growing threat to the environment. Therefore, the removal and separation of toxic and environmentally relevant heavy metal ions are a technological ...
Simplex optimization of artificial neural networks for the prediction of minimum detectable activity in gamma-ray spectrometry
(Elsevier, Amsterdam, 2006)
A three-layer feed-forward artificial neural network (ANN) with a back-propagation learning algorithm was used to predict the minimum detectable activity (AD) of radionuclides (Ra-226, U-238, U-235, K-40, Th-232, Cs-134, ...
