(Savez inženjera i tehničara tekstilaca Srbije, Beograd, 2004)
The part of results obtained during the investigation of synthesis of composites based on nonwoven textile materials (NTM) and alumosilicates are presented. The newly obtained material is composite agro textile that can ...
Associations of trace elements in aerosol at the South Adriatic Coast
(Springer Heidelberg, Heidelberg, 2004)
We applied statistical methods to the data of a 5-year sampling period to characterize the features of trace elements in airborne particulate matter at the South Adriatic Coast. The analysis of surface soil samples was ...
Superoxide dismutase activity as a function of culture aging of B-16 mouse melanoma cells / Aktivnost superoksid-dismutaze tokom maturacije kulture ćelija b-16 melanoma miša
(Serbian Chemical Society, 2004)
The C3 clone of B-16 mouse melanoma was cultured for 1, 6 and 9 days and analyzed. The changes which are not directly linked to melanogenesis in the B-16 / C3 cultures during their maturation were characterized. Early (1 ...
