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 ...
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 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 ...
Enhanced Cell-ID+TA GSM positioning technique
(IEEE, New York, 2005)
The majority of existing GSM positioning techniques can be described as either costly or with limited performance. Basic GSM positioning techniques Cell-ID and Cell-ID+TA can be upgraded to decrease positioning error. We ...
Assessment of Electrical Behavior of Non-Woven Textile Materials
(7th International Conference of the Balkan Physical Union, 2010)
Non-woven textile materials have been increasingly used for a variety of applications in industry and daily life. This imposes a need for the investigation of electrical properties in different conditions of their usage. ...
Environmental effects of raw pyrolysis gasoline storage and handling: Case study of refinery and petrochemical complex Pancevo, Serbia
(19th International Congress of Chemical and Process Engineering, CHISA 2010 and 7th European Congress of Chemical Engineering, ECCE-7, 2010)
A case study is presented that deals with Refinery and Petrochemical Complex, Pancevo, Serbia, in which handling of raw pyrolysis gasoline (RPG) has two possible pathways, i.e,, by pipelines to nearby refinery or transport ...
Power Generation from Low Enthalpy Geothermal Fields by Design and Selection of Efficient Working Fluids for Organic Rankine Cycles
(Aidic Servizi Srl, Milano, 2010)
The presented work addresses the efficient power generation from low enthalpy geothermal fields through design and selection of working fluids for organic Rankine cycle (ORC) processes. A systematic methodology is employed ...
