Water and water resources in national environmental strategy of Serbia / Nacionalni program zaštite životne sredine Srbije u oblasti voda i vodnih resursa
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
The Law on Environmental Protection of The Republic of Serbia ("The Official Gazette RS", Nr. 135/04) requires that the National Environmental Strategy is developed for the period of at least ten years. According to the ...
Complex estimation of woven fabrics bending ability
(Niscair, 2007)
The bending ability of cotton, wool and viscose woven fabrics under the action of their own weight has been examined using the direct indicators by cantilever method, and indirect indicators by disc method. The results ...
The crystallisation of calcium phosphate glass containing vanadium oxide
(University of Chemistry and Technology, Prague, 2007)
The crystallisation behaviour of calcium phosphate glass containing vanadium oxide was studied. Glass with a molar ratio of [CaO]/[P2O5] = 1.13 and a V2O5 content of 8 mol.% was prepared for the experiments. The crystallisation ...
Effect of temperature on the electrodeposition of disperse copper deposits / Uticaj temperature na elektrohemijsko taloženje disperznih taloga bakra
(Serbian Chemical Society, 2007)
The effect of temperature on the electrodeposition of copper at overpotentials belonging to the plateau of the limiting diffusion current density and higher was examined by the determination of the average current efficiency ...
Vapor-liquid equilibria of triglycerides-methanol mixtures and their influence on the biodiesel synthesis under supercritical conditions of methanol / Ravnoteža para-tečnost za sistem trigliceridi-metanol i njen uticaj na kinetiku sinteze biodizela pod uslovima natkritičnog metanola
(Serbian Chemical Society, Belgrade, 2007)
The non-catalytic synthesis of biodiesel (fatty acids methyl esters) from triglycerides and methanol proceeds at elevated pressures above 100 bar and temperatures above 523 K. Kinetic investigations of the system revealed ...
Carrier's mobility temperature dependence in analytical model of SiC based MOSFET structure current-voltage characteristics / Temperaturna zavisnost pokretljivosti nosilaca u analitičkom modelu strujno-naponskih karakteristika MOSFET strukture izrađene na bazi SiC
(Savez inženjera i tehničara Srbije, Beograd, 2007)
In this paper temperature dependence on current-voltage characteristics of a SiC based MOSFET structure is considered. This influence is modeled by introducing temperature impact on carrier's mobility. Proposed model ...
Application of inverse gas chromatography for polymer characterization / Primena inverzne gasne hromatografije za karakterizaciju polimera
(Association of Chemical Engineers of Serbia, 2007)
The possibility of polymer characterization by inverse gas chromatography (IGC) was illustrated with the study of sorption properties of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), ...
New functionalities in cellulosic fibers developed by chemical modification / Celulozna vlakna novih funkcionalnih svojstava dobijena hemijskim modifikovanjem
(Association of Chemical Engineers of Serbia, 2007)
This paper gives an overview of the current state in the field of cellulosic fibers functionalization by chemical modification. The emphasis is placed on the selective (periodate and TEMPO oxidation) and non-selective ...
Kinetic study of the reaction between sodium chloroacetate and potassium ethylxanthogenate / Kinetička ispitivanja reakcije između natrijum-hloracetata i kalijum-etil-ksantata
(Serbian Chemical Society, Belgrade, 2007)
The reaction kinetics of the synthesis of sodium ethyl xanthogeneacetate from potassium ethylxanthogenate and sodium chloroacetate in distilled water as the reaction medium at 25, 30, 35 and 40°C, were investigated. The ...
Surface characterization of silver and palladium modified glassy carbon
(Indian Acad Sciences, Bangalore, 2007)
In this work, the influence of silver and palladium on the surface of undoped, boron doped and phosphorus doped glassy carbon has been studied. The silver and palladium concentrations in solution, after metal deposition, ...
