Heat transfer conditions and ultrasonic measurements of alumina based refractories
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
In this paper temperature difference and resistance parameters were used for prediction of thermal shock behavior of alumina based commercial refractories with content of Al2O3 from 28 % to 78 %. Thermal and mechanical ...
Preparation of heterogeneous catalyst for biodiesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, e.g., fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies that are based on using heterogeneous catalyst. A new type of ...
Characterization of Intestinal Isolates of Lactic Acid Bacteria with Potential Probiotic Ability from Premature Born Nursling
(2008 Joint Central European Congress of the 4th Central European Congress on Food, CEFood 2008 and 6th Croatian Congress of Food Technologists, Biotechnologists and Nutritionists, 2008)
Five samples of feces from premature born nursling were taken from Institute of Neonatology (Belgrade). Three different media based on MRS was used for isolation of intestinal isolates of lactic acid bacteria. From 25 ...
Supercritical carbon dioxide extraction and fractionation of hyper for in and adhyperforin from St. John's Wort (Hypericum perforatum L.)
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
Plants of the genus Hypericum have been used as traditional medicinal plants in various parts of the world. St. John's Wort (Hypericum perforatum L.) has been reported as an antidepressive, antiviral, antimicrobial, ...
Use of nonlinear frequency response analysis for model discrimination: Example - DMFC anode kinetics
(18th International Congress of Chemical and Process Engineering, CHISA 2008, 2008)
Nonlinear frequency response analysis is proven as a powerful tool for the characterization of nonlinear systems. A set of frequency response functions (FRF), which contain different information, is obtained. In a number ...
Preparation of heterogeneous catalyst for biodlesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, i.e. fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies which are based on using heterogeneous catalyst. In this study a ...
The influence of low-temperature plasma treatment on some wool properties
(American Institute of Physics, 2004)
If swift heavy ions (5 MeV/u) hit solid targets energy is transferred to the electrons of the solid. Caused by the high electronic energy deposition along the flight path of the ion a cylindrical shaped chemical or structural ...
Supercritical carbon dioxide extraction of essential oils and mathematical modelling on the micro-scale - General model
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
General model for the supercritical carbon dioxide extraction of essential oils on the secretory structure scale (micro-scale) is presented in this study. The model containes Source and Transfer term which describes mass ...
Nechanisms of fracture in medium carbon vanadium microalloyed steels
(16th European Conference of Fracture, 2006)
Brewing by Immobilized Freeze Dried Cells in a Novel Gas Flow Bioreactor
(2008 Joint Central European Congress of the 4th Central European Congress on Food, CEFood 2008 and 6th Croatian Congress of Food Technologists, Biotechnologists and Nutritionists, 2008)
The aim of this study was to examine the novel gas-lift three phase bioreactor with external loop in beer fermentation by immobilized yeast cells on gluten pellets. Cells of Saccharomyces cerevisiae were immobilized on 40 ...
