(Association of the Chemical Engineers of Serbia, 2012)
The synthesis of the poly(N-isopropylacrylamide-co-2-hydroxypropyl-methacrylate) hydrogel along with the analysis of the residual monomers content and influence of monomer and crosslinker molar ratios on the swelling ...
Recovery of the damages of a welded steel structure of a coal-reloading bridge: Methodological approach
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
In present paper, the methodological approach to the analysis of the causes of failures and to recovery of the damages has been presented using, as an example, the fracture and damage of a welded steel structure of a ...
Effect of vibration on the variation of residual stresses and impact energy in butt-welded joints / Uticaj vibracija na promenu zaostalih napona i energije udara kod sučeono zavarenih spojeva
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An important segment occurring as a ...
Potential application of thermo-sensitive hydrogels for controlled release of phenacetin / Potencijalna primena termoosetljivih hidrogelova za kontrolisano otpuštanje fenacetina
(Association of Chemical Engineers of Serbia, 2012)
Over the past years, many scientific research studies have been focused on thermo-sensitive hydrogels containing N-isopropylacrylamide (NIPAM) as a monomer. The NIPAM based hydrogels with 20 mol% 2-hydroxypropyl methacrylate ...
