Digitally graded GaAs/Al0.44Ga0.56As quantum-cascade laser
(Elsevier, Amsterdam, 2003)
A method for the optimal design and realization of a GaAs/Al0.44Ga0.56As quantum-cascade laser (QCL) is presented. Firstly, an optimal, smooth active region profile is derived, using inverse spectral theory. A digitally ...
AN EXPLICIT CALCULATION OF RELATIVE SURFACE DEFORMATION DURING BURSTING TEST OF FABRICS
(The Society of Chemists and Technologists of Macedonia, 2003)
A mathematical approach to the setting of a new model of knitted and other loose textile surfaces deformation during a ball-bursting test is presented. The dependence of ball traverse length is defined in an implicit ...
Leaching of copper(I) sulphide by sulphuric acid solution with addition of sodium nitrate
(Elsevier, Amsterdam, 2003)
Finely grained samples of copper(I) sulphide were leached by H2SO4 solution with added NaNO3. The occurrence probability of chemical reactions was analysed based on literature data and products which were formed during the ...
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 ...
Primena plazme u oplemenjivanju vune
(Srpska akademija nauke i umetnosti, 2003)
Biomarkers of oil-type pollutants in surface soil
(Parlar Scientific Publications (P S P), Freising, 2003)
In this paper, biomarkers were applied for identification of oil-type pollutants in surface soil and their microbial changes were investigated. Samples were taken at destroyed fuel storage in Nis (Yugoslavia). Steranes, ...
New directions in hemp spinning / Novi pravci u predenju vlakna konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2003)
If hemp, besides flax the only textile fiber that Europe must not import, is ever to regain its lost ground in new circumstances of comfort and ecology, it must be through development of new products and new end uses. This ...
Analysis of fatigue and crack growth in carbon-fiber epoxy matrix composite laminates
(Strength of Materials, 2003)
A study of high frequency fatigue in carbon-fiber reinforced composites has been undertaken. A comparison has been made between the fatigue behavior of crossply (0 / 90) and angleply (± 45) carbon/epoxy unnotched and notched ...
Characteristics of looms for production woven fabrics made of agro cellulose fibers / Karakteristike razboja za proizvodnju tkanina od agroceluloznih vlakana
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2003)
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 ...
Electrochemical oxidation of methanol on Pt3Co bulk alloy / Elektrohemijska oksidacija metanola na leguri Pt3Co
(Serbian Chemical Society, Belgrade, 2003)
The electrochemical oxidation of methanol was investigated on a Pt3Co bulk alloy in acid solutions. Kinetic parameters such as transfer coefficient reaction orders with respect to methanol and H+ ions and energy of activation ...
