Determination of carbendazim residues in fruit juices by liquid chromatography-tandem mass spectrometry
(Taylor & Francis, 2005)
In this paper a rapid optimized method for routine analysis of carbendazim residues in fruit juices is reported. The procedure is based on matrix solid-phase dispersion (MSPD) with diatomaceous earth and analysis of the ...
Waste from electrical and electronic equipment / Otpad električnih i elektronskih proizvoda
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2005)
Intensive development of the electrical and electronic equipment industry causes generation of high quantities of specific wastes. Recycling of waste from electrical and electronic equipment (WEEE) is an important subject ...

Analytical model for the determination of bending properties of glass-epoxy composites / Primena analitičkog modela za određivanje savojnih svojstava staklo-epoksi kompozitnog materijala
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Mechanical properties of composite materials are conditioned by their structure and depend from the characteristic of structural components. In this paper the analytical model has been shown with which the bending properties ...
The surface energy of disperse cadmium electrodeposits formations / Површинска енергија електрохемијског формирања дисперзног талога кадмијума
(Serbian Chemical Society, 2005)
The surface energy of disperse cadmium electrodeposits formation was determined by using a procedure described earlier.1,2 It was shown that the surface energy strongly depends on the composition of the solution from which ...
