Ethylene glycol and glycolic acid production by wild-typeEscherichia coli
(Wiley, Hoboken, 2021)
Ethylene glycol and glycolic acid are bulk chemicals with a broad range of applications. The ethylene glycol and glycolic acid biosynthesis pathways have been produced by microorganisms and used as a biological route for ...
Microeconomics of the materials and energents consumption in a simulated copper casting process
(Edimet SpA, 2012)
An analytical model for the optimization of the consumption of materials and energents in a typical copper casting process based on a standard simulation procedure is presented. The proposed microeconomic analysis in ...
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 ...
Characterisation of biomedical titanium layers deposited by a vacuum plasma spray process
(Materiali in Tehnologije, 2021)
In this paper we will describe the process of the deposition of thick layers of VPS-Ti coating, which is used as a bonding layer for the upper porous Ti coatings on implant substrates. In order to deposit the powder, we ...
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 ...
The influence of service solutions on the longitudinal and circumferential tensile properties of glass-polyester composite pipes
(Springer, New York, 2011)
In numerous cases, metals and alloys traditionally used as structural materials in the process equipment can now be successfully replaced by nonmetallic composite materials. We study the influence of service solutions on ...
