Representation of lattices by fuzzy weak congruence relations
(Elsevier, Amsterdam, 2015)
Fuzzy (lattice valued) weak congruences of abstract algebras are investigated. For an algebra, the family of all such fuzzy relations is a complete lattice; its structure and cut properties are investigated and fully ...
Use of histopathology and elemental accumulation in different organs of two benthophagous fish species as indicators of river pollution
(Wiley, Hoboken, 2015)
The bottom feeding fish species have a good potential to be used for assessments of pollution, as they are under pressure from pollutants from both water and sediments. In this study, the level of similarity of histopathological ...
Structural investigation of mechanically activated ZnO powder
(Elsevier Science Sa, Lausanne, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...

Sandy everlasting [Helichrysum arenarium (L.) Moench] is herbaceous perennial plant belonging to Asteraceae family and it is native to Europe, Central Asia, and China. It belongs to the section HELICHRYSUM (Asteraceae ...
On the use of regional climate models: Implications of climate change for viticulture in Serbia
(Elsevier, Amsterdam, 2012)
Climate projections obtained from the coupled regional climate model EBU-POM (Eta Belgrade University - Princeton Ocean Model) driven by the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier Sci Ltd, Oxford, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
The influence of concentration and temperature on the viscoelastic properties of tomato pomace dispersions
(Elsevier Sci Ltd, Oxford, 2016)
The influence of concentration and temperature on the rheological properties of tomato pomace dispersions obtained by rehydration of lyophilized and grinded tomato pomace was investigated in this paper. Examined systems ...
Synthesis and characterization of a new type of levan-graft-polystyrene copolymer
(Elsevier Sci Ltd, Oxford, 2016)
Novel macromolecular graft copolymers were synthesized by reaction of the hydroxyl groups of the microbial polysaccharide levan, produced using Bacillus licheniformis, with polystyrene (Lev-g-PS). Synthesis was performed ...
Impact of energy saving cultivations on soil parameters in northern Kazakhstan
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Recently the cost of soil processing for agricultural production has been rapidly increasing because of expensiveness of agricultural machinery, energy, and agricultural chemicals. Intensive soil cultivation is costly and ...
Chemical Composition of Two Different Extracts of Berries Harvested in Serbia
(Amer Chemical Soc, Washington, 2013)
Total phenolic content (TPC), total anthocyanin content (TAC), free and total ellagic acid content, sugars, minerals, and radical scavenging activity were determined in nine berries harvested in Serbia. More than 30 phenolic ...
