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 ...
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 ...
Evaluation of different methods for determining growing degree-day thresholds in apricot cultivars
(Springer, New York, 2010)
The aim of this study was to examine different methods for determining growing degree-day (GDD) threshold temperatures for two phenological stages (full bloom and harvest) and select the optimal thresholds for a greater ...
Vertical distribution of 137Cs in cultivated and undisturbed areas / Vertikalna rasprostranjenost cezijuma-137 u obradivim i neobradivim zemljištima
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper introduces the distribution BACKGROUND: and unique characteristics of 137Cs in cultivated and undisturbed areas. The samples were taken from three measuring points of the depth of 1 m. We examined all visible ...
Correlations between statistical moments of soil aggregate size distributions
(International Agrophysics, 2010)
In this paper, following the common practice, the shapes of soil particles size distributions are quantified by higher-order statistical parameters: skewness, flatness, superskewness, superflatness, hyperskewness and ...
Fungi in the apple sooty blotch and flyspeck complex from Serbia and Montenegro
(Journal of Plant Pathology, 2010)
Sooty blotch and flyspeck (SBFS) is a late season disease complex of apple and pear caused by epiphytic fungi that blemish the fruit surface, resulting in economic losses in humid regions worldwide. The SBFS disease complex ...
Morphogenetic responses of embryo culture of wheat related to environment culture conditions of the explant donor plant
(Univ Sao Paolo, Cerquera Cesar, 2010)
Availability of immature embryos as explants to establish wheat (Triticum aestivum L.) by tissue culture can be limited by climatic factors and the lack of high quality embryos frequently hampers experimentation. This study ...
New Type of Beer - Beer with Improved Functionality and Defined Pharmacodynamic Properties
(University of Zagreb, 2010)
The paper highlights the facts about the possibilities of improving the functionality of beer with extracts of thyme (Thymus vulgaris), lemon balm (Melissa officinalis) and mushroom Ganoderma lucidum. It briefly summarizes ...
Pruning effect on content of quercetin and catechin in berry skins of cv. Blaufrankisch (Vitis vinifera L.)
(Turkish Journal of Agriculture and Forestry, 2010)
The effect of pruning severity on quercetin and catechin content in berry skins of cv. Blaufrankisch (Vitis vinifera L.) was studied over 3 years. Different crop levels and canopy structures were obtained by retaining 8, ...
