(Springer, New York, 2010)
This study was aimed to assess the levels of selected heavy metals and pesticides in soil and plant products from an agricultural area of Belgrade, Serbia and to indicate possible sources and risks of contamination. Soil, ...
Antioxidant Effects of Glechoma hederacea as a Food Additive
(SAGE Publishing, 2010)
The antioxidant properties of Glechoma hederacea L. (Lamiaceae), of Serbian origin, were studied in respect to its potential use in foodstuffs. Ethanol-water (8:2, v/v) and purified ethyl acetate extracts of the plant were ...
The Effects of the pH Value of the Swelling Medium on the Kinetics of the Swelling of a Poly(acrylic acid) Hydrogel
(John Wiley & Sons Inc, Hoboken, 2010)
The isothermal kinetics curves of the swelling of a poly(acrylic acid) hydrogel in buffer solutions of different pH values (5, 7, and 9) at temperatures ranging from 30 to 40 degrees C were determined. The possibilities ...
Influence of mechanical activation on microstructure and crystal structure of sintered MgO-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100°-1400°C for 2h. The decrease in powder's ...
Benefits of Environmental Conditions for Growing Coriander in Banat Region, Serbia
(SAGE Publishing, 2011)
As one of the oldest multi-purpose plants (spice, aromatic, honey and medicinal), coriander is widespread across Europe. Although in Serbia there are favorable conditions fir its growth and development, it is grown on ...
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 ...
Solid Phase Microextraction as an Efficient Method for Characterization of the Interaction of Pesticides with Different Soil Types
(Sociedade Brasileira de Química, 2010)
A solid phase microextraction (SPME) method for simultaneous determination of 20 pesticides belonging to various pesticide groups in soil samples was developed. Extraction conditions, such as fibre type, desorption temperature ...
Grain characteristics and composition of maize specialty hybrids
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2011)
Improved nutritive and technological maize grain value is very important for its use in diets. In this work, the chemical composition and potential beneficial components, including total and soluble proteins, tryptophan, ...
Dehydration investigations of a refractory concrete using DTA method
(Springer, Dordrecht, 2012)
The base mix refractory concrete is corundum-based, containing corundum as refractory aggregate and CAC as hydraulic binder, with a spinel as an additive. The authors investigated the dehydration reactions which occur from ...
