Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
Comparative examination of activity of different strains of lactic acid bacteria in beetroot and carrot juice / Uporedna ispitivanja aktivnosti sojeva bakterija mlečno-kiselinskog vrenja u soku cvekle i mrkve
(Faculty of Technology, Novi Sad, 2000)
Fermented vegetable juices are an important component of nutrition, because the fermentation improves the quality of natural vegetable juices by its products, which are important biotic substances. Beetroot (Beta vulgaris ...
Karakteristike kvašenja pletenina na bazi konoplje namenjenih za medicinske svrhe / Liquid wetting properties of hemp based knitted fabrics for hospital uses
(Savez inženjera i tehničara tekstilaca Srbije, 2006)
U okviru ovog rada pletenine na bazi konoplje podvrgnute su ispitivanju maksimalnog kapaciteta apsorpcije tečnosti kao i brzine njene apsorpcije. S obzirom da su za izradu pletenina upotrebljene nehomogene kompleksne pređe ...
Solvent and structural effects on the kinetics of the reactions of 2-substituted cyclohex-1-enylcarboxylic and 2-substituted benzoic acids with diazodiphenyl with diazodiphenylmethane
(Wiley, Hoboken, 2007)
The rate constants for the reaction of 2-methyl-cyclohex-1-enylcarboxylic, 2-phenylcyclohex-1-enylcarboxylic, and 2-methylbenzoic and 2-phenylbenzoic acids with diazodiphenyl-methane were determined in 14 various solvents ...
Relation between selected heavy metal concentrations in wheat from growing regions of Serbia
(Journal of Environmental Protection and Ecology, 2005)
The content of heavy metals in representative wheat samples taken from all important wheat growing regions of Serbia was analysed, Concentration of 8 trace elements in 14 wheat samples was determined by atomic absorption ...
Removal of methyl tertiary butyl ether from wastewaters using photolytic, photocatalytic and microbiological degradation processes
(Elsevier Science Bv, Amsterdam, 2007)
Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods ...
Kinetic of corrosion reactions in acid and neutral solutions on electrochemically deposited Ni-W alloys / Kinetika korozionih reakcija u kiselim i neutralnim rastvorima na elektrohemijski taloženim legurama Ni-W
(Engineering Society for Corrosion, Belgrade, Serbia, 2006)
Ni-W alloys were electrochemically deposited from an ammonia-citrate electrolyte on rotating disc electrode with a gold disc, by direct and pulsating current. The corrosion potential and kinetics of cathodic and anodic ...
Compressional behavior of knitted fabrics exposed to repeated wash and wear cycles / Kompresibilnost pletenina podvrgnutih testu nege i nošenja
(Association of Chemical Engineers of Serbia, 2006)
The quality requirements of knitted fabrics nowadays have become highly demanding in terms of appearance and comfort properties. It is well known that yarns are subjected to tension, bending, torsion and compression during ...
The effect of TiO 2 on the structure and devitrification behavior of potassium titanium germanate glass
(Springer Netherlands, 2006)
The effect of replacing 20 mol% of GeO 2 by TiO 2 on the properties of potassium germanate glass was investigated. The structure and devitrification behaviour of glasses were studied by Fourier transform infrared spectroscopy ...
Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
