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, ...
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 ...
