Prediction of thermal shock behavior of alumina based refractories: Temperature difference, fracture resistance parameters and water quench
(Trans Tech Publications Ltd, Durnten-Zurich, 2001)
In this paper temperature difference and fracture resistance parameters were used for prediction of thermal shock behavior of the samples. Materials were alumina based commercial refractories with different content of Al2O3 ...
Solubility and Pitzer's ionic parameters in the system H2O-NaCl-MgCl2
(University of Belgrade, Technical Faculty, Bor, 2001)
The object of this work was to determine Pitzer's ionic parameters, θ and Ψ, for the mixed salt solution H2O-NaCl-MgCl2 at following temperatures: 273.15, 298.15, 356.15 and 378.15 K in ionic strength interval from 7 to ...
Starter cultures for semi hard cheese / Starter kulture za polutvrdi sir
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad i Savez hemičara i tehnologa, Beograd, 2001)
29 starter cultures for semi hard cheese are formed from natural isolates of lactic acid bacteria. They are isolated from traditionally home made cheese produced without the addition of starter cultures. Natural isolates ...
Material properties and thermal shock behavior of alumina based refractories
(Belgian Ceramic Soc, Mons, 2001)
Materials were five alumina based commercial refractories with different contents of ( Al2O3 + TiO2) from 28 % to 78 %. Thermal and mechanical properties of the chosen materials, were measured using standard laboratory ...
The influence of a cryoprotective medium containing glycerol on the lyophilization of lactic acid bacteria / Uticaj krioprotektivnog medijuma sa glicerolom na liofilizaciju bakterija mlečne kiseline
(Serbian Chemical Society, 2001)
The aims of lyophilization (freeze-drying) of lactic acid bacteria are to preserve pure cultures or to prepare starters for the dairy industry. In both cases, the choice of the cryoprotectant is very important. In this ...
Development of steels for fabrication of welded constructions with improved safety / Razvoj čelika za izradu zavarenih konstrukcija povišene sigurnosti
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2001)
Physical and metallurgical basis of historical steel development and some modern solutions for specific applications, together with predictions and projections of future development are reviewed in this paper. Undoubtedly, ...
NMR analysis of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene / NMR analiza 2-(2',3'-dihidro-1'H-inden-1'-il)-1H-indena
(Serbian Chemical Society, Belgrade, 2001)
1H, 13C and two dimensional NMR analyses were applied to determine the NMR parameters of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene. The chemical shifts of all the H- and C-atoms, as well as the appropriate coupling ...
Computational studies in the AlPO4-34 system
(Kluwer Academic Publ, Dordrecht, 2001)
The lattice energies of the as-synthesized fluoride-containing chabazite-like aluminophosphate (AlPO4-34F) and of the corresponding metal-substituted materials [MeAPO-34F, Me = Mn(II), Co(II), Ni(II)] have been calculated ...
Mathematical modeling of gel drying with supercritical carbon dioxide / Matematičko modelovanje sušenja gela natkritičnim ugljen dioksidom
(Association of Chemical Engineers of Serbia, 2001)
The most complex step in the production of aerogels is the supercritical drying step, and it is therefore important to study its dynamics using mathematical models. Alumina/silica aerogel was obtained using a one step ...
Characterization of aged elastic explosives based upon pentrite and polyurethane binder by differential scanning calorimetry and infrared spectrophotometry / Ispitivanje starenih elastičnih eksploziva na bazi pentrita i poliuretanskog veziva diferencijalnom skenirajućom kalorimetrijom i infracrvenom spektrofotometrijom
(Vojnotehnički institut, Beograd, 2001)
Elastic explosives, based upon two types of binder antioxidants, were artificially aged at 60 and 80°C, and in cycles at -30 and +60°, during four months. The aging effects on the samples of elastic explosives were examined ...
