Development of a packed bed bioreactor for cartilage tissue engineering / Razvoj bioreaktorskog sistema sa pakovanim slojem za primenu u inženjerstvu tkiva hrskavice
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2006)
Efficient transport of regulatory molecules is one of the main requirements for directing the growth and differentiation of bone marrow stromal cells (BMSC). We have designed and utilized a packed bed bioreactor system for ...
Determination of AL2O3particle size in Cu-AL2O3 nanocomposite materials using UV spectrophotometry / Određivanje veličine čestica AL2O3 u nanokompozitnim materijalima iz sistema Cu-AL2O3 primenom UV spektrofotometrije
(Savez inženjera metalurgije Srbije, Beograd, 2008)
In order to achieve improved mechanical properties of dispersion strengthened nanocomposite, without influencing electrical and thermal conductivity it is necessary for dispersoide to be nano sized and uniformly distributed ...
Influence of the woven construction on breaking load and relaxation / Uticaj Konstrukcije Tkanine na Prekidnu Silu i Relaksaciju
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2001)
A study is made to establish the correlation between a woven construction and its mechanical strength. Dynamometric tests are carried out to determine the breaking load and breaking extension of three wooltype fabrics, as ...
Influence of the heat treatment on the tribological characteristics of the Ti-based alloy for biomedical applications
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2009)
The influence of diverse heat treatments on micro-structural and tribological characteristics of Ti-6Al-4V ELI (mass%) alloy, which is used as implant material in biomedical engineering, was investigated on a block-on-disc ...
Characterization of nano-powder morphology obtained by ultrasonic spray pyrolysis
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Spherical nanosized particles of copper were synthesized by ultrasonic dispersion of solutions from copper sulphate in the temperature range of 800-900°C in hydrogen atmosphere. A controlled particle size was realized ...
The influence of residual stresses on welded joints and other inhomogeneous materials with cracks / Uticaj zaostalih napona na ponašanje zavarenih spojeva i drugih nehomogenih materijala sa prslinama
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
Residual stresses in many structural components are often produced during the fabrication or bonding processes, due to the cooling from elevated temperatures. Examples for such behavior are: welded and soldered joints, ...
Investigation of antimicrobial activity of encapsulated essential oils
(8th Conference of the Yugoslav Materials Research Society, 2007)
Antimicrobial activity of essential oils obtained from many plants has been known for a long time. However, the use of essential oils as active components of biomedical textile have recently gained popularity and aroused ...
Production of bioethanol from corn meal hydrolyzates
(Elsevier Sci Ltd, Oxford, 2006)
The two-step enzymatic hydrolysis of corn meal by commercially available a-amylase and glucoamylase and further ethanol fermentation of the obtained hydrolyzates by Saccharomyces cerevisiae yeast was studied. The conditions ...
Complex evaluation of elastic characteristics of clothing wool fabrics by 'DA Q XIAO q' method / Kompleksna ocena elastičnih karakteristika vunenih odevnih tkanina 'DA Q XIAO q' metodom
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2002)
Chinese method "DA Q XIAO q" is applied on 18 samples of clothing wool fabrics made in three variants of weaves (plain, twill 2/2, cross-twill) aimed at establishing the complex evaluation of elasticity of investigated ...
Solvent effect on electronic absorption spectra of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids / Efekti rastvarača na elektronske apsorpcione spektre cikloheks-1-enilkarbonske i 2-metilcikloheks-1-enilkarbonske kiseline
(Serbian Chemical Society, Belgrade, 2000)
The ultraviolet absorption spectra of cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in six protic and nine aprotic solvents in the wavelength range from 200 to 400 nm. The position ...
