Relationship between Mechanical Characteristics and Thermal Shock Behaviour of Alumina Based Refractories
(InterCeram: International Ceramic Review, 2003)
The thermal stability of the refractory material with the Al 2 O 3 content of 42 mass-% was investigated. Water quench tests (JUS.B.D8.319.) were carried out. The dynamic Young modulus of elasticity was calculated using ...
Solids holdup and pressure drop in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2003)
Fundamentally based model for pressure drop in gas-flowing solids-fixed bed contactors is presented, together with a phenomenological semiempirical model for prediction of dynamic holdup. These simple models do not require ...
The system parameters influence on the particle circulation in the fountain-fluidized bed with the central pipe / Uticaj parametara sistema na cirkulaciju čestica u fontansko-fluidizovanom sloju sa centralnom cevi
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2003)
Fluid-mechanical investigations of fountain-fluidized bed with the central pipe were conducted on a cylindrical column of 250mm diameter, 45şC conical bottom, 50mm nozzle and built-in central pipe of 250mm diameter with ...
Improvement to the Flynn-Wall method of determining apparent activation energies of the thermal degradation of polymers
(Amer Chemical Soc, Washington, 2003)
An improvement to the Flynn-Wall method of determining apparent activation energies of the thermal degradation of polymers is presented. The method involves the deconvolution of differential thermogravimetric (TG) curves ...
Semi-IPNs based on polyacrylamide and poly(itaconic acid)
(Springer, New York, 2003)
Semi-IPNs based on polyacrylamide (PAAm) and poly(itaconic acid) (PIA) were prepared by two different techniques, polymerizing itaconic acid in the presence of polyacrylamide gel (Samples I) and by makiug the polyacrylamide ...
Uticaj vlažnosti sredine na električnu otpornost tekstilnih materijala / Influence of humidity on textile materials electrical resistance
(Savez inženjera i tehničara tekstilaca Srbije, 2003)
Razvijeni su postupci za ocenu zavisnosti električne otpornosti tekstilnih materijala od vlažnosti sredine. Korišćen je uređaj koji su autori ranije konstruisali, i za tu svrhu snabdeli komorom koja obezbeđuje definisanu ...
Excess molar volume of acetonitrile + alcohol systems at 298. 15 K. - Part II: Correlation by cubic equation of state / Dopunska molarna zapremina sistema acetonitril + alkohol na 298.15 K. - II deo - korelisanje pomoću kubne jednačine stanja
(Serbian Chemical Society, Belgrade, 2003)
The excess molar volume VE of the binary liquid systems acetonitrile methanol and acetonitrile + ethanol, experimentally determined in the previous part, were correlated by the PRSV CEOS coupled with the vdW and TCBT mixing ...
Radical polymerization of monoethyl itaconate / Radikalna polimerizacija monoetil itakonata
(Association of Chemical Engineers of Serbia, 2003)
The radical polymerization of monoethyl itaconate (MEI) was investigated in bulk and in solution at 60°C using a,a'-azobisisobutyronitrile as initiator. It was established that the obtained polymer poly(monoethyl itaconate) ...
Phase topology of a NR/BR elastomer blend with active filler / Fazna topologija elastomernih blendi NR/BR sa aktivnim punilom
(Association of Chemical Engineers of Serbia, 2003)
The relations between the structure and mechanical properties of a polymer blend of natural (NR) and polybutadiene (BR) rubber (i.e. a NR/BR blend with the weight ratio of the components 70/30) filled with active carbon ...
