Modeling of microenvironmetal restricted yeast cell growth within Ca-alginate microbead
(Minerva Biotecnologica, 2008)
Aim. A phase-field mathematical model was formulated to describe yeast cell growth within the Ca-alginate microbead during air-lift bioreactor cultivation. Model development was based on experimentally obtained data for ...
Adsorption of itaconic acid from aqueous solutions onto alumina / Adsorpcija itakonske kiseline iz vodenih rastvora na aluminijum-oksidu
(Serbian Chemical Society, Belgrade, 2008)
Itaconic acid, IA (C5H6O4), was investigated as a potential flocculant for the aqueous processing of alumina powders. The adsorption of IA, as a function of its concentration and pH value of the solution, onto the alumina ...
Study of the simulated heat affected zone of creep resistant 9-12% advanced chromium steel
(Taylor & Francis Inc, Philadelphia, 2008)
Global warming leads to research-development attempts worldwide with a view to reduce CO2 emission. Therefore, in the energy supply sector, a special focus has been directed to further development of steels that can endure ...
Benzylation of N-phenyl-2-phenylacetamide under microwave irradiation / Benzilovanje N-fenil-2-fenilacetamida pomoću mikrotalasnog zračenja
(Serbian Chemical Society, Belgrade, 2008)
N-Phenyl-2-phenylacetamide was alkylated with benzyl chloride in the presence of powdered potassium hydroxide under microwave irradiation in a solvent-free system. The reactions were also performed in the presence of ...
Heat transfer coefficient and pressure drop during refrigerant R-134a condensation in a plate heat exchanger
(Versita, Warsaw, 2008)
The condensation heat transfer coefficient and the two-phase pressure drop of refrigerant R-134a in a vertical plate heat exchanger were investigated experimentally. The area of the plate was divided into several segments ...
Isopiestic investigation of the osmotic and activity coefficients of {yMgCl(2)+(1-y)MgSO4}(aq) and the osmotic coefficients of Na2SO4 center dot MgSO4(aq) at 298.15 K
(Springer/Plenum Publishers, New York, 2008)
Isopiestic vapor-pressure measurements were made for {yMgCl(2) + (1-y)MgSO4}(aq) solutions with MgCl2 ionic strength fractions of y = (0,0.1997,0.3989,0.5992,0.8008, and 1) at the temperature 298.15 K, using KCl(aq) as the ...
Surface carriers' concentration dynamics caused by a small alternating applied voltage
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
One of our previous papers was devoted to threshold voltage in MOSFETs and MODFETs viewed as a problem of nonlinear dynamics. The behavior of surface carriers' concentration under D.C. (direct current) applied voltage has ...
The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition / Jonska ravnoteža u sistemu CuSO4-H2SO4-H2O i formiranje strukture pčelinjeg saća elektrohemijskim taloženjem bakra
(Serbian Chemical Society, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
Thermal stability of cordierite/silicon carbide composites after cyclic thermal shock
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
In this paper composite material made from silicium carbide and cordierite was used in experiments. Behavior of the material in conditions of rapid temperature changes was investigated. Modified water quench test was applied ...
Implementation of a quality management system in meteorological practice in Serbia
(Springer, New York, 2008)
An optional approach in the meteorological service Quality Management System (QMS) based on the case study of the Republic Hydrometeorological Service (MHS) of Serbia is presented and discussed in this paper. The idea is ...
