Cleaner metallurgical industry in Serbia: A road to the sustainable development
(Association of the Chemical Engineers of Serbia, 2009)
Since the sustainable development has been a global and fundamental objective, a metallurgical industrial sector faces some of the most difficult sustainability challenges of any industrial sector. On the other hand, the ...
Influence of microstructure and phase composition on the nanoindentation characterization of bioceramic materials based on hydroxyapatite
(Elsevier Sci Ltd, Oxford, 2009)
The aim of the study was to investigate the influence of microstructure and phase composition on the mechanical behaviour of hydroxyapatite (HAp) and biphasic HAp/beta-tricalcium phosphate (beta-TCP) bioceramic materials ...
Sol-Gel Combustion Synthesis of La-9.33(SiO4)(6)O-2 Oxyapatite
(Taylor & Francis Inc, Philadelphia, 2009)
Synthesis of La-9.33(SiO4)(6)O-2 was performed by a new method that represents the combination of sol-gel and combustion procedures using glycine as the fuel. Syntheses were performed from ethanol-water solutions of oxides ...
Influence of Hydrolysis on the Osmotic Coefficients of the System {yZnCl(2) + (1-y)ZnSO4}(aq) at Temperature 298.15 K
(Amer Chemical Soc, Washington, 2009)
Isopiestic vapor pressure measurements were made for {yZnCl(2) + (1 - y)ZnSO4}(aq) solutions with ZnCl2 ionic strength fractions of y = (0.2640, 0.5042, 0.7533, and 1) at the temperature 298.15 K, using KCl(aq) as the ...
Behavior of silicon carbide/cordierite composite material after cyclic thermal shock
(Elsevier Sci Ltd, Oxford, 2009)
In the present work Mg-exchanged zeolite and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70. Samples were exposed to the water quench test from 950 ...
Setup of combined creep crack growth model / Postavke kombinovanog modela razvoja prsline u uslovima puzanja
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
The paper sets up the combined criteria for creep crack growth (CCG) assessment. The CCG model considering influence of creep damage on mechanics of fracture correlates the crack growth rate, damage factor and damage factor ...

Rezidualna količina pesticida kao parametar tehnološkog kvaliteta sirovina biljnog porekla
(Poslovna politika AD, Beograd, 2009)
Pesticidi se upotrebljavaju širom sveta za zaštitu uroda tokom uzgoja i skladištenja. Poznato je da upotreba pesticida povećava prinose, ali u prekomernim količinama može da naruši kvalitet i zdravstvenu ispranost namrnica. ...
Natural resources protection by municipal solid waste recycling / Očuvanje prirodnih resursa reciklažom materijala iz komunalnog otpada
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2009)
Rapid population growth, urbanization and industrial growth have led to severe waste management problems in the cities of developing countries. The improper management of municipal solid waste is a major source of air, ...
A novel bioreactor with mechanical stimulation for skeletal tissue engineering
(Association of the Chemical Engineers of Serbia, 2009)
The provision of mechanical stimulation is believed to be necessary for the functional assembly of skeletal tissues, which are normally exposed to a variety of biomechanical signals in vivo. In this paper, we present a ...
