Seasonal water pricing using meteorological data: case study of Belgrade
(Elsevier Sci Ltd, Oxford, 2012)
The paper presents a model of seasonal water pricing (SWP) aimed primarily at diminishing excessive fresh water use in the city of Belgrade. Seasonal prices are determined on meteorological observations of the average ...
Interpretation of hybrid x sowing date interaction for oil content and oil yield in sunflower
(Elsevier, Amsterdam, 2012)
Due to the presence of an interaction, it is often difficult to recommend which sunflower hybrids should be planted based on specific sowing dates or production regions. Through this study, the hybrid x sowing date (H x ...
Antioxidative activities and chemical characterization of polysaccharide extracts from the widely used mushrooms Ganoderma applanatum, Ganoderma lucidum, Lentinus edodes and Trametes versicolor
(Academic Press Inc Elsevier Science, San Diego, 2012)
Antioxidant activities of polysaccharide extracts of four of the most widely known mushrooms often used in medicinal applications as well as in tea and food, namely Ganoderma applanatum, Ganoderma lucidum, Lentinus edodes ...
Rhizome and root yield of the cultivated Arnica montana L., chemical composition and histochemical localization of essential oil
(Elsevier, Amsterdam, 2012)
Arnica montana (L) is a medicinal plant whose flower heads are widely used for the topical treatment of bruises and sprains in phytopharmaceutical preparations. Despite being cultivated for flower heads production for a ...
Effectiveness assessment of agricultural machinery based on fuzzy sets theory
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The quality of service of agricultural machinery represents one of the basic factors for successful agricultural production. In this sense, there is a clear need for defining the exact indicator of the quality of these ...
Preparation of highly conductive carbon cryogel based on pristine graphene
(Elsevier Science Sa, Lausanne, 2012)
In this paper we report fabrication and characterization of highly conductive carbon cryogel. The carbon cryogels were prepared by the sol-gel polymerization of resorcinol and formaldehyde in an aqueous surfactant stabilized ...
Vertical distribution of natural radionuclides in soil: Assessment of external exposure of population in cultivated and undisturbed areas
(Elsevier, Amsterdam, 2012)
In the present work, naturally occurring radionuclides U-238, Th-232 and K-40 were measured in soil samples from the cultivated and undisturbed areas in Rudovci, municipality of Lazarevac, Serbia. There were three profiles, ...
Yield and yield components of imidazolinone-resistant sunflower (Helianthus annuus L.) are influenced by pre-emergence herbicide and time of post-emergence weed removal
(Elsevier Science Bv, Amsterdam, 2012)
With an increase in the use of imidazolinone (IMI)-resistant sunflower, it is important to determine the influence of weed interference and herbicide presence on seed yield and yield components of sunflower. The objective ...
Exploring diversity of Erwinia amylovora population in Serbia by conventional and automated techniques and detection of new PFGE patterns
(Springer, Dordrecht, 2012)
Forty Erwinia amylovora strains originating from different host plants and locations in Serbia and one strain from Montenegro were characterized by conventional, automated and molecular techniques. All strains were ...
Enthalpy-entropy compensation for n-hexane adsorption on HZSM-5 containing transition metal ions
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
In this work, the values of entropy changes related to n-hexane adsorption onto ion-exchanged ZSM-5 zeolites were calculated from differential heats, obtained from microcalorimetric experiments. The existence of enthalpy-entropy ...
