Quantification of transfer of U-238, Ra-226, Th-232, K-40 and Cs-137 in mosses of a semi-natural ecosystem
(Elsevier Sci Ltd, Oxford, 2010)
There is a lack of appropriate data on transfer of some radionuclides on many terrestrial biota groups. To expand the available data concentration ratios of U-238, Ra-226, Th-232, K-40 and Cs-137 in mosses are presented ...
Impedance Response and Dielectric Relaxation in Liquid-Phase Sintered Zn2SnO4-SnO2 Ceramics
(Springer, New York, 2010)
Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn2SnO4-SnO2 ceramics. The measurements were performed over a wide ...

The influence of operational conditions on the reliability and tractor Massey- Ferguson 8160 service life is analyzed in the work. Experimental data have been provided by acquiring the operational parameters, malfunction ...
The effect of the crop rotation on the weed floristic composition in winter wheat / Uticaj plodoreda na floristički sastav korova u ozimoj pšenici
(Savez poljoprivrednih inženjera i tehničara, Beograd, 2010)
The goal of a crop rotation is to create an unstable environment that discourages weeds from becoming established in the field. The paper deals with results on the crop rotation effects on weed synusia including the weed ...
Fast Fourier Transform IR Characterization of Epoxy GY Systems Crosslinked with Aliphatic and Cycloaliphatic EH Polyamine Adducts
(MDPI, BASEL, 2010)
The use of fast FT-IR spectroscopy as a sensitive method to estimate a change of the crosslinking kinetics of epoxy resin with polyamine adducts is described in this study. A new epoxy formulation based on the use of ...
Comparison of different methods for determination of sodium chloride in cheese / Poređenje različitih metoda određivanja natrijum-hlorida u siru
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd, 2010)
The content of NaCl (weight fraction of Cl-ions, in %) was analysed in different cheeses, which were bought in supermarkets, and made by domestic manufacturers. Sodium chloride in cheese samples was analysed after the ...
