Cardiac tissue engineering
(Association of Chemical Engineers of Serbia, 2004)
The restoration of normal cardiac function can potentially be achieved by functional tissue constructs grown in vitro by using differentiated or progenitor cells, biomaterial scaffolds and bioreactors. Engineered tissues ...
The influence of low-temperature plasma treatment on some wool properties
(American Institute of Physics, 2004)
If swift heavy ions (5 MeV/u) hit solid targets energy is transferred to the electrons of the solid. Caused by the high electronic energy deposition along the flight path of the ion a cylindrical shaped chemical or structural ...
Synthesis of new hyperbranched urethane-acrylates and their evaluation in UV-curable coatings
(Elsevier Science Sa, Lausanne, 2004)
Three series of hyperbranched urethane-acrylates (HB-UA), based on aliphatic hyperbranched polyesters and polyethyleneglycol acrylate, were prepared and evaluated for use in UV-curable coatings. UV-curing kinetics were ...
Optimization of artificial neural network for retention modeling in high-performance liquid chromatography
(Elsevier, Amsterdam, 2004)
An artificial neural network (ANN) model for the prediction of retention times in high-performance liquid chromatography (HPLC) was developed and optimized. A three-layer feed-forward ANN has been used to model retention ...
Protective properties of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Fe alloys / Zaštitna svojstva epoksidnih kataforetskih prevlaka na čeliku elektrohemijski modifikovanom Zn-Fe legurama
(Association of Chemical Engineers of Serbia, 2004)
Epoxy coatings were electrodeposited on steel and steel modified by Zn-Fe alloys using the constant voltage method. Zn-Fe alloys were electrodeposited on steel at different current densities. The effect of the Zn-Fe alloy ...
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 ...
