Nechanisms of fracture in medium carbon vanadium microalloyed steels
(16th European Conference of Fracture, 2006)
Selection of natural materials for In situ remediation and prevention of environment contamination by lead
(Grafima Loannis Tsarouchidis, Thessaloniki, 2002)
Stability of the solid matrix - contaminant system represents a crucial parameter in selection of the appropriate natural material for in situ remediation of the environment contaminated by toxic heavy metals. We have ...
Application of plasma in wool processing
(Serbian Acad Sciences Arts, Belgrade, 2002)
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 ...
Treatment of heavy metals contaminated solid wastes-Stabilization
(4th European Metallurgical Conference, EMC 2007, 2007)
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 ...
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, ...
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 ...
Comparison of training algorithms in neural network modeling of gamma spectrometric uncertainty
(Belgrade : The Society of Physical Chemists of Serbia, 2004)
A three-layer feed-forward artificial neural network with six different algorithms applied on different training sets was used to model uncertainties of activity
levels of eight radionuclides (226Ra, 238
U, 235
U, 40K, ...
Optimization of a neural network model for signal-to-background prediction in gamma-ray spectrometry
(Belgrade : Vinča Institute of Nuclear Sciences, 2004)
The artificial neural network (ANN) model was optimized for the prediction of signal-tobackground (SBR) ratio as a function of the measurement time in gamma-ray
spectrometry. The network parameters: learning rate (α), ...
