(Institute for Medicinal Plants Research "Dr. Josif Pancic", 2013)
The Lamiaceae family, which contains about 200 genus and 3000 species, has a cosmopolitan distribution. Plants of this family are rich in essential oils and phenol compounds. Thymus vulgaris (Thyme) is perennial, subshrub ...
Assessment of pressure vessel load capacity in the presence of cracks / Procena nosivosti posude pod pritiskom u prisustvu prsline
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
The paper illustrates the structural assessment of an investigated pressure vessel, made of low-alloyed high strength steel, with an external surface crack located on the shell wall. In order to assess the remaining strength ...
Prediction models of non-ferrous secondary raw materials formation
(University of East Sarajevo, Faculty of Technology, 2013)
For the prediction of formation of non-ferrous processing and accumulating waste both model of balancing and model of correlation and regression analysis can be employed, while the dynamic model can be applied only for the ...

Electrochemical oxidation of methanol on Pt/(RuxSn1-x)O2 nanocatalyst / Elektrohemijska oksidacija metanola na katalizatoru Pt/(RuxSn1-x)O2
(Serbian Chemical Society, Belgrade, 2013)
Ru-doped SnO2 powder, (RuxSn1-x)O2, with a Sn:Ru atomic ratio of 9:1 was synthesized and used as a support for Pt nanoparticles (30 mass % loading). The (RuxSn1-x)O2 support and the Pt/(RuxSn1-x)O2 catalyst were characterized ...
Analysis of copper losses throughout weak acid effluent flows generated during off-gas treatment in the new copper smelter RTB Bor
(Association of Metallurgical Engineers of Serbia, 2013)
The previous inadequate treatment of off-gas in RTB Bor in Serbia has resulted in serious pollution of the environment and the possibly high losses of copper through the effluent flows. The project of New Copper Smelter ...
