Preliminary characterization of lactic acid bacteria isolated from Zlatar cheese
(Wiley, Hoboken, 2007)
Aims: Isolation, characterization and identification of lactic acid bacteria (LAB) from artisanal Zlatar cheese during the ripening process and selection of strains with good technological characteristics. Methods and ...
Thermodynamic and structural investigation of the Ag-In-Sb system
(Croatian Metallurgical Society, 2007)
The Ag-In-Sb ternary system presents one of the possible lead-free solder candidates. Therefore, the results of thermodynamic study of the alloys in the Ag-In-Sb alloys, obtained using general solution mode!, are presented ...
Concentrations of Cu, Zn, Cd and Pb in urban soils in parks and green areas of Belgrade / Zagađenje metalima urbanog zemljišta u parkovima i zelenim površinama u Beogradu
(Association of the Chemical Engineers of Serbia, 2006)
Several metals in urban soils of Belgrade were extracted by two methods which respectively give estimates of the available and "quasi total" contents. Soil samples were collected from six parks and three green areas within ...
Experimental design approach regarding kinetics of high pressure leaching processes / Dizajniranje eksperimenata u pogledu na kinetiku luženja pri visokim pritiscima
(Savez inženjera metalurgije Srbije, Beograd, 2003)
Kinetics of high pressure leaching of nickel latente ore "Rudjinci", Serbia was studied in this work. The following parameters: temperature, acid to ore ratio, stirring speed, and time were optimized in order to obtain the ...
Influence of heat input on HAZ hardness distribution after surfacing two Q+T steels / Uticaj pogonske energije zavarivanja na raspodelu tvrdoće u ZUT pri navarivanju čelika za poboljšanje
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2002)
The aim of this work was to determine the influence of welding heat input on hardness distribution after SURFACING of two quench+temper steels. The results indicate that variation of heat input can partially provide required ...
