Ordinal scale and its application in classification analysis / Kvantifikacija ordinalne skale i njena primena u analizi grupisanja
(Statističko društvo Srbije, Beograd, 1999)
The application of the classification analysis on the set of nonquantitative indicators expressed as an ordinal scale is possible with additional transformations on the scale in sense that a (sensible( numerical mark must ...
SEM investigation of domain structure in (Ba,Ca,Pb)TiO3
(Elsevier Sci Ltd, Oxford, 1999)
In the present paper the microstructure and domain structure in modified BaTiO3 with Pb and Ca as additives have been investigated using SEM technique. The (Ba,Pb)TiO3 and (Ba,Ca,Pb)TiO3 ceramics show a slight difference ...
Treatment of ovine footrot with zinc sulfate/sodium lauryl sulfate footbaths
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 1999)
Seven groups of sheep, with a total of 365 animals were used to determine the efficacy of treating ovine footrot by footbathing in aqueous zinc sulfate solution (20% w/v) or aqueous zinc sulfate solution (20% w/v) with ...
CO interaction with zeolites studied by TPD and FTIR: transition-metal ion-exchanged FAU-type zeolites
(Elsevier, Amsterdam, 1999)
The interaction of carbon monoxide with the cationic Lewis acid sites of transition-metal (Fe2+, Co2+, Ni2+) and Cu2+-exchanged Y and X zeolites was investigated by Fourier transform infrared spectroscopy (FTIR) and ...
A modification of a method for phytic acid determination
(Srpsko hemijsko društvo, Beograd, 1999)
Several different methods for the determination of phytic acid which do not require sophisticated equipment are currently in use. These methods have been developed to measure the phytic acid content of a variety of materials, ...
Effects of excessive levels of sodium selenite on daily weight gain, mortality and plasma selenium concentration in chickens
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 1999)
One hundred and five, one day old unsexed Hybro chickens divided into 7 groups, were fed basal diets supplemented with 0, 2, 5, 10, 20 and 30 mg Se/kg as sodium selenite for 6 weeks. The Se level of 2 mg/kg feed had no ...
Dielectric properties of barium-titanate sintered from tribophysically activated powders
(Elsevier Sci Ltd, Oxford, 1999)
It has been well known that the tribophysical (mechanical) activation could be used as a method for modification of physicochemical properties of dispersed systems such as polycrystalline mixture of oxides. In this study, ...
