Calculation of elasticity modulus of particulate composite biomaterials using finite element method / Numeričko određivanje modula elastičnosti čestično kompozitnih biomaterijala primenom metode konačnih elemenata
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2003)
The influence of particle geometry, volume fraction and particle distribution on the modulus of elasticity of a hydroxyapatite (HAp) particulate reinforced polymer (poly -L-lactide) matrix composite biomaterial was ...
Electrochemical synthesis and corrosion behavior of thin polyaniline film on mild steel / Elektrohemijska sinteza i koroziono ponašanje tankih filmova polianilina na mekom čeliku
(Engineering Society for Corrosion, Belgrade, Serbia, 2003)
The electrochemical synthesis of polyaniline (PANI) on mild steel from the sodium-benzoate solutions has been investigated. It has been concluded that thin, highly adherent, polyaniline films could be obtained by anodic ...
Studies of a wear resistant cast iron / Izučavanje belih gvožđa otpornih na habanje
(Savez inženjera metalurgije Srbije, Beograd, 2003)
The objective of this investigation was to set down (on the base of the results obtained by the examination of white cast iron alloys with different content of the alloying elements) a correlation between chemical composition ...

Influence of the background electrolyte on the point of zero charge of chromium(III)-oxide
(Trans Tech Publications Ltd, Durnten-Zurich, 2003)
The Point of zero charge of chromium(Ill)-oxide (pH(pzc)) was investigated by a batch equilibration method. The effect of several background electrolytes, in the concentration range of 10(-5)-10(-1) mol/dm(3), on pH(pzc) ...
Saturated-liquid heat capacity: New polynomial models and review of the literature experimental data / Toplotni kapacitet zasićene tečnosti - novi polinomski modeli i pregled literaturnih podataka
(Serbian Chemical Society, Belgrade, 2003)
In this paper a review of selected literature experimental data for saturated-liquid heat capacities was presented. Two-, three- and four-parameter polynomial correlation models are tested on those data. Obtained results ...

(Elsevier, 2003)
The result of the investigation on methyl esters obtained on the basis of heated refined sunflower oil and used frying oils are given in the paper. Transesterification reaction conditions that affect yield and purity of ...
Ni alloyed steels for low temperature service / Čelici legirani niklom za rad na niskim temperaturama
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2003)
A metallurgical base of alloying in cryogenic steels is presented in this paper. The common use of these steels is for tanks for liquid gases. Main alloying element is Ni, added in amounts between 2.25 and 9 % due to ...
The combined low-temperature, plasma/enzyme wool shrink-resist treatment
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 2003)
To successfully achieve shrink resistance, an enzymatic treatment was applied to knitted fabrics previously treated with a radio-frequency low-temperature plasma. Shrink resistance was attained at the machine-washable level ...
