Micromechanical coupled study of crack growth initiation criterion in pressure vessel steel
(Strength of Materials, 2004)
We present results of the combined design-theoretical investigation of the mechanism of crack growth at the onset of ductile fracture of NPP reactor pressure vessels. Micromechanical approach to the prediction of ductile ...
Optimization of arsenic behavior during concentrate roasting process
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
Copper concentrates almost always contain certain quantity of arsenic, from 0.01-1%. Domestic concentrates processed in Bor Smelting Plant usually contain small quantity of arsenic (0.05-0.15%) except from Bor concentrate ...

This paper presents investigation of possibility of heavy metals contaminated solid wastes treatment form Bor Site, Serbia. Presented remediation technology is stabilization, which can effectively reduce content of ...
Neural network prediction of the gas chromatographic separation of polycyclic aromatic hydrocarbons
(Belgrade : The Society of Physical Chemists of Serbia, 2004)
This paper describes the application of artificial neural networks (ANNs) method
to the modeling of 13 polycyclic aromatic hydrocarbons (PAHs)retentionsin temperature - programmed gas chromatography.The ANN method used ...
Sorption of Ni2+ by different synthetic hydroxyapatite
(Belgrade : The Society of Physical Chemists of Serbia, 2004)
Two hydroxyapatite (HAP) samples of different crystallinity were studied as a
nickel immobilization matrix. Sorption isotherms were obtained by batch equilibration
method, in the concentration range 1.
10-4 – 8.

Analysis of in vivo substitution of bone tissue by HAp/PLLA composite biomaterial with PLLA of different molecular weights using FTIR spectroscopy
(Uetikon-Zuerich : Trans Tech Publ, 2000)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial with PLLA of 50,000 and 430,000 g/mole molecular weight was studied in vivo. The biocomposite with PLLA of both molecular weights was implanted into mice and ...
Mobility of Contaminants originated from Bombing of an Oil rafinery in Serbia
(Proceedings of an International Conference, Protection and Restoration of the Environment V", Thassos, Greece, July 3-6 (2000), 2000)
Further results on singular time delayed system stability
(Institute of Electrical and Electronics Engineers Inc., 2005)
This paper gives sufficient conditions for the stability of linear singular continuous delay systems of the form Eẋ(t) -A 0 x(t) + A 1 X(t -τ). These new, delay-independent conditions are derived using approach based on ...
Use of multivariate analysis in radioecological and environmental radoactivity studies - advantages and limitations
(Østerås : Norwegian Radiation Protection Authority, 2008)
Some of the most commonly occuring problems in radioecological and environmental
radioactivitiy studies when applying traditional statistical models are multivariate and
multiscale structures of data. Spatial data analysis ...
Local heat transfer coefficients during refrigerant R-134a evaporation in a vertical plate heat exchanger
(18th International Congress of Chemical and Process Engineering, CHISA 2008, 2008)
The evaporation heat transfer coefficient of refrigerant R-134a in a vertical plate heat exchanger was investigated. The area of the plate was divided into several segments along the vertical axis. For each of the segments, ...
