Evaluation of the potential of periodically operated reactors based on the second order frequency response function
(Inst Chemical Engineers, Rugby, 2008)
A new, fast and easy method for analysing the potential for improving reactor performance by replacing steady state by forced periodic operation is presented. The method is based on Volterra series, generalized Fourier ...
Nanostructured bioglass thin films synthesized by pulsed laser deposition: CSLM, FTIR investigations and in vitro biotests
(Elsevier, Amsterdam, 2008)
We report the synthesis by pulsed laser deposition of thin structures of two bioactive glasses belonging to the SiO2-Na2O-K2O-CaO-MgO-P2O5 system, on medical grade Ti substrates. We evaluated their biocompatibility after ...
A correlation for heat of vaporization of pure compounds
(Korean Institute Chemical Engineers, Seoul, 2008)
Twenty-seven selected equations were tested on 162 compounds with 1958 calorimetric data for their abilities to reflect the temperature influence on the heat of vaporization of pure compounds. A new equation is recommended ...
Chemical composition and antimicrobial activity of essential oil of wild-growing Salvia officinalis L. from Montenegro
(Taylor & Francis Ltd, Abingdon, 2008)
The essential oil composition of wild-growing Salvia officinalis L. (Lamiaceae) from Montenegro was analysed by GC-FID and GC-MS and its antimicrobial activity tested at different oil concentrations, Twenty-five compounds ...
Cavitation damage of the medium carbon steel: Implementation of image analysis
(Elsevier Science Bv, Amsterdam, 2008)
Cavitation damage of the medium carbon steel was performed using the modified vibratory cavitation test set up. Erosion rates were measured by analytical method. The morphology of damage under cavitation action was determined ...
Lipase catalyzed synthesis of flavor esters in non-aqueous media: Optimization of the yield of pentyl 2-methylpropanoate by statistical analysis / Sinteza mirisnih estara katalizovana lipazama u nevodenoj sredini - optimizacija prinosa pentil-2-metilpropanoata statističkom analizom
(Serbian Chemical Society, Belgrade, 2008)
In this study, the synthesis of pentyl 2-methylpropanoate employing a commercial lipase from Candida rugosa was investigated, the emphasis being placed on analyzing the effects of various process conditions on the yield ...
Thermal shock damage characterization of high temperature ceramics by non destructive test methods
(University of Chemistry and Technology, Prague, 2008)
In the present work a mixture of commercially available spinel, quartz (SiO2) and alumina (Al2O3) corresponding to cordierite stoichiometry was used as starting material for obtaining cordierite/SiC composite ceramics with ...
The possibilities of waste waters and waste processing in industry of fruit processing and fruit juices production / Mogućnosti obrade otpadnih voda i otpada u industriji prerade voća i proizvodnje voćnih sokova
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2008)
The basic characteristics of technological waste waters and industrial waste of agricultural industry, as well as of industry of fruit processing and production of juices, are high values of organic contamination and ...
Significance of cracks in the heat-affected-zone of steels for elevated temperature application / Značaj prslina u zoni uticaja toplote čelika za povišene temperature
(Society for Structural Integrity and Life, Institute for Material Testing, 2008)
Damage and failure of welded joints are classified according to the crack position. Type IV cracking occurs in welded joints in creep-resistant steels, due to enhanced rate of creep void formation in the presence of coarse ...
Adsorption of itaconic acid from aqueous solutions onto alumina / Adsorpcija itakonske kiseline iz vodenih rastvora na aluminijum-oksidu
(Serbian Chemical Society, Belgrade, 2008)
Itaconic acid, IA (C5H6O4), was investigated as a potential flocculant for the aqueous processing of alumina powders. The adsorption of IA, as a function of its concentration and pH value of the solution, onto the alumina ...
