What does current web-based education lack?
(International Journal of Computers and Applications, 2003)
Current web-based education has its limitations, most of which can be divided into three categories: conceptual, technological, and tool related. This article describes the three categories in detail and discusses possible ...
Selectivity in extraction of copper and indium with chelate extractants
(Skopje : Macedonian union of metallurgists, 2003)
Simultaneous extraction of copper and indium with chelate extractants (LIX84 and D2EHPA) was
described. Stechiometry of metal-organic complexes examined using the method of equimolar ratios resulted in
CuR2 and InR3 forms ...

In this paper technical characteristics and possibilities of single phase and multiphase looms for production of woven fabrics made of agro cellulose fibers of some world lieder manufacturers of looms are described. In the ...
Surface composition and adsorption properties of activated carbon cloth
(Belgrade : Institute of Technical Sciences of SASA, 2003)
Surface properties of activated carbons have shown to play an important role in
adsorption process. The presence of various functional groups (such as phenolic, carbonyl,
carboxylic) on the carbon surface depends on the ...
Inverse gas chromatography study of synthetic hydroxyapatite surface by hexane adsorption at finite surface coverage
(Belgrade : Institute of Technical Sciences of SASA, 2003)
The sorption of both organic and inorganic substances on synthetic hydroxyapatite
(HAP) was studied intensively in the last decade, due to HAP application in diverse fields of
science and technology. In this paper, HAP ...

Glass transition temperature determination of macroporous copolymer by inverse gas chromatography
(Belgrade : Institute of Technical Sciences of SASA, 2003)
The glass transition temperature, Tg, of crosslinked macroporous glycidyl
methacrylate, GMA, based copolymer was studied by inverse gas chromatography at zero
surface coverage (IGC-ZC). The specific retention volumes, ...
The kinetics of the hydrogen evolution reaction on zinc in EDTA solutions in the pH 3-10 range
(Elsevier Science Sa, Lausanne, 2003)
Polarization curves of the hydrogen evolution reaction on zinc were obtained in Ethylenediaminetetraacetic acid (EDTA) solutions of different total molar concentrations (0.05, 0.10, 0.15 and 0.20 mol dm(-3)), the pH values ...
