Pretreatment of used vegetable oil using CaO and CaO-ZnO for biodiesel production
(Czech Society of Chemical Engineering, 2014)
Investigation of probiotic potential of Leuconostoc sp. and Lactobacillus sp. natural isolates from non-commercial milk and water kefir
(6th Central European Congress on Food, CEFood 2012, 2012)
Non-commercial milk and water kefir grains (from a household in Belgrade, Serbia) were used for isolation of lactic acid bacteria on TSA, MRS and M17 agar. Preliminary identification has been performed according to ...
Comparative Microhardness Analysis of Various Thin Metallic Multilayer Composite Films
(IEEE, New York, 2012)
Different composite systems of electrodeposited monolayered and multilayered thin metal films of Ni and Cu on cold-rolled copper substrates were made. Thin metal layers were deposited at narrow spacing of 300 nm and 150 ...
