Physical properties and organic matter of Fluvisols under forest, grassland, and 100 years of conventional tillage
(Elsevier Science Bv, Amsterdam, 2013)
Although a large number of papers deal with effects of land-use change on soil properties, less attention is directed to the long-term effects of different land-use types on soil physical properties and organic matter in ...
The effect of heat treatment and skimming on precipitate formation in caprine and bovine milks
(Cambridge Univ Press, New York, 2015)
Caprine and bovine milks have a similar overall gross composition, but vary considerably in the ratios of their casein components. These differences in colloidal casein micelles could affect directly or indirectly the heat ...
Gold(III) complexes with esters of cyclohexyl-functionalized ethylenediamine-N,N '-diacetate
(Elsevier Science Inc, New York, 2013)
Six novel gold(III) complexes containing O,O'-dialkyl-(S,S)-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoate ([AuCl2{(S,S)-R(2)eddch}]PF6, R = Me, Et, n-Pr, n-Bu, i-Bu, i-Am; 1-6, respectively) were synthesized and ...
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 ...
Radionuclides in the soil around the largest coal-fired power plant in Serbia: radiological hazard, relationship with soil characteristics and spatial distribution
(Springer Heidelberg, Heidelberg, 2015)
Primordial radionuclides, U-238, Th-232 and K-40 were determined in soil samples collected at two depths (0-10 and 10-20 cm) in the vicinity of the largest coal-fired power plant in Serbia, and their spatial distribution ...
The effects of geothermal water inflow on longitudinal changes in benthic macroinvertebrate community composition of a temperate stream
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Studies of macroinvertebrate communities in thermal streams are highly geographically localized and mostly faunistical, making the efforts to understand in situ water thermal regime effects on those biocoenoses barely ...
Effect of the maize-soybean intercropping system on the potential bioavailability of magnesium, iron and zinc
(Csiro Publishing, Clayton, 2015)
This study concerned the effect of different intercropping systems (alternating rows and alternating strips) of maize and soybean compared with single cropping, in combination with different fertilisers (biofertiliser, ...
Ferroelectric nanocomposites of polyvinylidene fluoride/polymethyl methacrylate blend and BaTiO3 particles: Fabrication of beta-crystal polymorph rich matrix through mechanical activation of the filler
(Amer Inst Physics, Melville, 2014)
Nanocomposites of polyvinylidene fluoride/polymethyl methacrylate (PVDF/PMMA) blend and mechanically activated barium titanate (BaTiO3) particles were prepared by melt mixing. Modification of filler by means of mechanical ...
Detecting population admixture in honey bees of Serbia
(Taylor & Francis Ltd, Abingdon, 2014)
Honey bee workers were sampled across the Serbian territory during 2009-2010 from mostly non-migratory apiaries to determine the population structure of these bees using morphometric, genetic, and spatial information. A ...
Biointerface dynamics - Multi scale modeling considerations
(Elsevier, Amsterdam, 2015)
Irreversible nature of matrix structural changes around the immobilized cell aggregates caused by cell expansion is considered within the Ca-alginate microbeads. It is related to various effects: (1) cell-bulk surface ...
