Hydrogenation of oil produced by naphtha steam pyrolysis: Determination of catalyst activity / Hidrogenovanje pirolitičkog ulja nastalog u procesu pirolize primarnog benzina - određivanje aktivnosti katalizatora
(Association of Chemical Engineers of Serbia, 2000)
Residual pyrolysis oil (RPO) produced as a by-product of naphtha steam pyrolysis was hydrogenated (160-280°C; 60 bar; trickle-bed reactor with Co-Mo/y-AlgOs) with the aim of suppressing the polymerization of the unsaturated ...
Conservation of the Archaeological Finds from Roman Period
(UNIVERSITY OF TIMISOARA, 2012)
A degree of preservation of iron artefacts depends on the type of underground environment and the type of
corrosion products formed on their surface. This paper analyses the conditions of an archaeological artefact made ...
Simultaneity analysis in a wireless sensor network
(Polska Akad Nauk, Polish Acad Sciences, Warszawa, 2015)
An original wireless sensor network for vibration measurements was designed. Its primary purpose is modal analysis of vibrations of large structures. A number of experiments have been performed to evaluate the system, with ...
Removal of copper(II) ion from aqueous solution by high-porosity activated carbon
(Water Research Commission, Pretoria, 2013)
The removal of copper(II) ion from aqueous solution by the granular activated carbon, obtained from hazelnut shells (ACHS) (Corylus avellana L. var. lunga istriana), was investigated. The ACHS was prepared from ground dried ...
The analysis of forming PVB-SiO2 nanocomposite fibers by the electrospinning process / Analiza formiranja PVB-SiO2 nanokompozitnih vlakana pomoću elektrospining procesa
(Vojnotehnički institut, Beograd, 2011)
The poly (vinyl butyral)-silica (PVB-SiO2) nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt.% where ethanol was used as the solvent. The ...
Thermal resistance testing of standard and protective filtering military garment on the burning napalm mixture / Testiranje termičke otpornosti standardne i filtrirajuće zaštitne vojničke uniforme na goruću napalm smešu
(Association of Chemical Engineers of Serbia, 2013)
Fires are an accompanying manifestation in modern weaponry use and in various accidents in peacetime. The standard military uniform is a primary barrier in protection of a soldier's body from all external influences, ...
Functionalization of thermo-acid activated sepiolite by amine-silane and mercapto-silane for chromium(VI) adsorption from aqueous solutions / Adsorpcija hroma(VI) iz vodenih rastvora na termo-kiselinski aktiviranom sepiolitu funkcionalizovanom amino-silanom i merkapto-silanom
(Association of Chemical Engineers of Serbia, 2013)
Chromium(VI) adsorption from aqueous solutions onto thermo-acid activated sepiolite functionalized with (3-mercaptopropyl)trimethoxy-silane and [3-(2-aminoethylamino)propyl]trimethoxy-silane was investigated. Scanning ...
The effect of accelerated aging on the mechanical properties of PMMA denture base materials modified with itaconates / Uticaj ubrzanog starenja na mehanička svojstva poli(metil-metakrilatnih) materijala za bazu zubnih proteza modifikovanih itakonatima
(Association of Chemical Engineers of Serbia, 2011)
This study evaluated the effect of accelerated aging on tensile strength, elongation at break, hardness and Charpy impact strength in commercial PMMA denture base material modified with di-methyl itaconate (DMI) and ...
