Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
Biomarkers of oil-type pollutants in surface soil
(Parlar Scientific Publications (P S P), Freising, 2003)
In this paper, biomarkers were applied for identification of oil-type pollutants in surface soil and their microbial changes were investigated. Samples were taken at destroyed fuel storage in Nis (Yugoslavia). Steranes, ...
Bioethanol production by immobilized Sacharomyces cerevisiae var. ellipsoideus cells
(African Journal of Biotechnology, 2009)
Bioethanol can be produced by fermentation of sugars from various waste agricultural materials. Whichever system for bioethanol production is chosen, the attention must be paid to the overall economics and energy consumption. ...
Solvent and structural effects on the kinetics of the reactions of cycloalkenylcarboxylic and cycloalkenylacetic acids with diazodiphenylmethane
(Wiley, Hoboken, 2005)
The rate constants for the reaction of different cycloalkenylcarboxylic, cycloalkenylacetic acids, and phenylacetic acid with diazodiphenylmethane were determined in 12 aprotic solvents at 30 degrees C. in order to explain ...
Hydroxylic solvent effects on the reaction rates of diazodiphenyl methane with 2-substituted cyclohex-1-enylcarboxylic and 2-substituted benzoic acids: Part II
(Natl Inst Science Communication, New Delhi, 2005)
The rate constants for the reaction of diazodiphenylinethane with 2-substituted cyclohex-1-enylcarboxylic acids, determined in butan-1-ol, 2-methylpropan-1-ol and ethylene glycol, together with the rate constants determined ...
Study of heavy metal pollution in sediments from the Iron Gate (Danube River), Serbia and Montenegro
(HARD, 2005)
The pollution of aquatic ecosystems by heavy metals has assumed serious proportions due to their toxicity and accumulative behavior. River dams are especially at risk of contamination by different contaminants from ...
Ductile fracture prediction of steam pipeline steel
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Considering the conditions to which steels used for the manufacture of steam pipelines are exposed, the micromechanism of their destruction in exploitation is exclusively the ductile one. In order to make an estimation of ...
The estimation of solid copper surface tension in copper sulfate solutions
(Journal of the Serbian Chemical Society, 2002)
In metal electrodeposition in the limiting diffusion current density range, the deposition current density remains constant regardless of the deposition overpotential used, At the same time, die larger the deposition ...
Analysis of the transferability of micromechanical parameters of damage of steel under the conditions of ductile-fracture initiation
(Springer, New York, 2002)
For the description of the mechanical behavior of a cracked material, we use a macromechanical model of fracture based on the well-known criterion of plastic yield for porous materials. This model is realized as a computational ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
