Numerical modeling of ductile fracture initiation in structural steel / Numeričko modelisanje inicijalizacije daktilne frakture u strukturnom čeliku
(University of Niš, 2001)
Numerical modeling of ductile fracture initiation on a precracked geometry, taking into account the behaviour of simple uncracked material, has been done in the scope of micromechanical analysis. Numerical simulation has ...
A new current line division concept for the determination of the current distribution in electrochemical cells. Part I. Theoretical background of the corner weakness effect in electroforming / Нов концепт поделе струјних линија за одржавање расподеле струје у електрохемијским ћелијама. Део I.Теоријске основе појаве "Corner weakness" у галванопластици
(Belgrade : Serbian Chemical Society, 2000)
A new approach to the determination of the current distribution in electrochemicalcells, the current line division concept, is introduced. The new concept, based on thebasic equations of electrics and electrochemical ...
Antifreeze life cycle assessment: II. Mathematical modelling / Životni ciklus antifriza: II. Rezultati matematičkog modelovanja
(Association of Chemical Engineers of Serbia, 2005)
A mathematical model based on the mass and energy balances of all the processes included in antifreeze life cycle assesment (LCA) was defined in the first part of this study [1]. The part of energy that can be transformed ...
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 ...
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 ...
Influence of the hemp component in non-homogeneous yarns on the elastic behavior of knits made therefrom / Uticaj komponente na bazi konoplje u nehomogenim pređama na elastično ponašanje pletenina
(Association of the Chemical Engineers of Serbia, 2005)
One of the aims of producing non-homogeneous yarns is the improvement of their mechanical, aesthetic and comfort properties. In the case of hemp yarns, known by their predominantly technical uses, non-homogeneous yarns ...
An analysis of occurrence and beginning of stable crack growth in the low-alloyed steel for pressure vessels / Analiza nastanka i početka stabilnog rasta prsline u niskolegiranom čeliku za posude pod pritiskom
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2003)
Pressure vessels are often made of low-alloyed steel that should be characterized by proper values of strenght, toughness, formability and weldability. In this paper the crack initiation in low-alloyed ferritic steel (Rp0.2 ...
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 ...
Reactivity of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids with diazodiphenylmethane in aprotic solvents / Reaktivnost cikloheks-1-enilkarbonske i 2-metilcikloheks-1-enilkarbonske kiseline sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2000)
Rate constants for the reaction of diazodiphenylmethane with cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in nine aprotic solvents, as well as in seven protic solvents, at 30 ...
Saw surfacing of the worn part of crane wheel with flux cored wire / Navarivanje EPP-postupkom istrošenog dela točka dizalice primenom punjene žice
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2006)
This paper presents results of repairing a ring part and rolling surfaces of the crane wheel by SAW method with flux cored wire. Optimal quality of flux cored wire for crane wheel repairing is defined by weld metal hardness ...
