Ecobiological study of medicinal plants in some regions of Serbia
(Czech Academy Agricultural Sciences, Prague, 2006)
Ecobiological study of medicinal plants includes the analysis of particular soil features and the ecological indexes of plant species as site indicators. Two experimental serpentine areas in northwest and central Serbia ...
The use of image analysis for the interaction of 1,3,5-trisubstituted isocyanurates with oxidizer and different binders in composite materials / Korišćenje analize slike za utvrđivanje interakcije 1,3,5-trisupstituisanih izocijanurata sa oksidansom i različitim vezivima u kompozitnim gorivima
(Association of Chemical Engineers of Serbia, 2006)
Composite propellants are non-homogenous propellants and comprise primarily crystalline oxidizer and metal fuels uniformly suspended in a resin binder. The strength of the bonds between the polymer matrix and the oxidizer ...
Surface characteristics and modification of different carbon materials
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
In this work, surface characteristics of different carbon materials were investigated. The materials under consideration were: activated carbon, carbon monolith, carbon felt and glassy carbon (powder, plate and broken ...
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 ...
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 ...
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 ...
Assessment of gamma dose rates from terrestrial exposure in Serbia and Montenegro
(Oxford Univ Press, Oxford, 2006)
The gamma dose rates due to naturally occuring terrestrial radionuclides (Ra-226, Th-232 and K-40) were calculated based on their activities in soil samples, determined by gamma-ray spectrometry. A total of 140 soil samples ...
Laminar composite materials damage monitoring by embedded optical fibers
(16th European Conference of Fracture, 2006)
Investigation of the interfacial bonding in composite propellants. 1,3,5-trisubstituted isocyanurates as universal bonding agents / Proučavanje međusobnih veza komponenata u kompozitnim gorivima. 1,3,5-trisupstituisani izocijanurati kao univerzalni vezivni agensi
(Serbian Chemical Society, Belgrade, 2006)
A series of 1,3,5-trisubstituted isocyanurates (substituents: CH2CH2OH CH2CH=CH2 and CH2CH2COOH) was synthesized according to a modified literature procedure. Experimental investigations included modification of the synthetic ...
