The effects of aging on the precipitation of the W-rich phase in the matrix of the 92.5W-5Ni-2,5Fe powder metallurgy heavy alloys
(Association of Metallurgical Engineers of Serbia (AMES), Beograd, 2013)
The precipitation behavior of W-rich phase on the specific matrix locations of
Co-free and Co-containing 92.5W-5Ni-2.5Fe heavy alloys is investigated during
aging of the as-quenched samples. The aging treatment is ...
The influence of long-term aging on the properties of TEMPO oxidized cotton / Uticaj dugotrajnog starenja na svojstvo TEMPO oksidisanog pamuka
(Belgrade : Union of Engineers and Textile Technicians of Serbia, 2023)
Cotton yarns were 2,2,6,6-tetramethy|piperidine-1-oxy radical (TEMPO) oxidized, i.e., oxidation was carried out in the presence of sodium hypochlorite, sodium bromide and TEMPO, during different time intervals (30, 60 and ...

Walsh analysis - a convenient preprocessor for period detection in astronomy
(Astronomical Observatory Belgrade, 2016)
Walsh analysis is practically analogous to Fourier analysis, except that square wave is used instead of the sine one. It has one major advantage over Fourier - it can be performed much faster. This may seem of little ...
Određivanje veštačkog zaslađivača saharina u uzorcima otpadne vode / Determination of artificial sweetener saccharin in wastewater samples
(Beograd : Beogradska politehnika, 2019)
Široka primena veštačkih zaslađivača u prehrambenoj i farmaceutskoj industriji počela je početkom osamdesetih godina prošlog veka. Većina ovih jedinjenja se ne metaboliše u ljudskom telu i izlučuje se uglavnom nepromenjena. ...
