Low-pressure rf plasma and corona decolourisation of indigo dyed denim fabrics
(Astronomical Observatory, Belgrade, 2008)
This study was aimed to investigate the influence of low-pressure RF plasma (gas, treatment time and power) and atmospheric pressure corona (number of passages and power) parameters on decolourisation of indigo dyed denim ...
Analysis of the composite and film hardness of electrodeposited nickel coatings on different substrates
(Elsevier Science Sa, Lausanne, 2008)
Fine-grained nickel thin films were electrodeposited from a self-made sulphamate-based electrolyte on different substrates: polycrystalline cold-rolled copper and single crystal silicon with two different orientations, ...
A fracture mechanics approach to thermal shock investigation in alumina-based refractory
(9th International Conference on Multiscale and Functionally Graded Materials, FGM IX, 2008)
The thermal shock behavior of large grain size, alumina-based refractories was investigated experimentally using a standard water quench test. A mathematical model was employed to simulate the thermal stability behavior. ...
Temperature dependence of densities and excess molar volumes of the ternary mixture (1-butanol plus chloroform plus benzene) and its binary constituents (1-butanol plus chloroform and 1-butanol plus benzene)
(Springer/Plenum Publishers, New York, 2008)
Densities rho of the 1-butanol + chloroform + benzene ternary mixture and the 1-butanol + chloroform and 1-butanol + benzene binaries have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and ...
The influence of bonding agents in improving interactionsin composite propellants determined using image analysis
(Wiley, Hoboken, 2008)
Binder-oxidizer interactions in rocket composite propellants can be improved using adequate bonding agents. In the present work, the effectiveness of different 1,3,5-trisubstituted isocyanurates was determined by stereo ...
Fermentation processes by immobilized cell systems in beverage production
(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)
Immobilized cell technology has been investigated and used in various bio-industries as well as in processes based on alcoholic fermentation, like beer, wine and cider fermentation processes. Some of the most important ...
Corrosion stability of epoxy coatings on aluminum pretreated by vinyltriethoxysilane
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The electrochemical and transport properties and adhesion of epoxy coatings electrodeposited on aluminum pretreated by vinyltriethoxysilane (VTES) were investigated during exposure to 3% NaCl. The VTES films were deposited ...
Electrochemical synthesis and characterization of hydroxyapatite powders
(Elsevier Science Sa, Lausanne, 2008)
Electrochemical synthesis of hydroxyapatite powders was performed galvanostatically from homogeneous solution of Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 at a concentration relationship Ca/EDTA/PO43- of 0.25/0.25/0.15 ...
Assessment of viscoelastic crack bridging toughening in refractory materials
(Elsevier Sci Ltd, Oxford, 2008)
Viscoelastic bridges can be formed in refractory ceramics while cooling from high temperatures. Such bridges can shield crack tips, thus reducing the effective crack tip stress intensity factors leading to higher resistance ...
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 ...
