Influence of thermal treatment on phenolic compounds and antioxidant properties of oak acorns from Serbia
(Elsevier Sci Ltd, Oxford, 2007)
The aim of the present work was to investigate and compare phenolic compounds and antioxidant activity of methanol extracts of Quercus robur and Quercus cerris acorn kernels obtained before and after thermal treatment. ...
The adsorption of nicotine from aqueous solutions on different zeolite structures
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The present work is focused on the adsorption of nicotine from aqueous solutions. Based on the data available in the literature, serious concern is claimed regarding the appearance of nicotine in ground, surface and municipal ...
LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
(Elsevier, Amsterdam, 2008)
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
Energy efficiency optimization of combined ventilation systems in livestock buildings
(Elsevier Science Sa, Lausanne, 2010)
Good ventilation system in livestock buildings is necessary for removing excess moisture and heat and for improving building environment in general. Natural ventilation does not require energy consumption and on the other ...
Resistance of Listeria monocytogenes, Escherichia coli O157:H7 and Campylobacter jejuni after exposure to repetitive cycles of mild bactericidal treatments
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
While maintaining nutritional and sensorial attributes of fresh foods mild processing technologies generally deliver microbiologically perishable food products. Currently little information exists on possible increase in ...
Comparison of tillage systems according to fuel consumption
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Nowadays, tractor is still the basic power unit in almost all production processes in agriculture, including tillage. The structure of tractor-machinery systems depends on many parameters: seeding system, soil conditions, ...
A review of bottom-up building stock models for energy consumption in the residential sector
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Efficient and rational implementation of building stock CO(2) emission reduction strategies and policies requires the application of comprehensive building stock models that have the ability to: (a) estimate the baseline ...
The investigation of phenol removal from aqueous solutions by zeolites as solid adsorbents
(Elsevier, Amsterdam, 2010)
This work reports results on phenol adsorption from aqueous solutions on synthetic BEA (beta) and MFI (ZSM-5) zeolites, studied by heat-flow microcalorimetry. For the sake of comparison, the adsorption was performed on ...
Oxidation of CO over Ru containing perovskite type oxides
(Elsevier Science Bv, Amsterdam, 2006)
Perovskite type catalysts La0.7Sr0.3Cr1-xRuxO3 (0.025 lt = x lt = 0.100) were synthesized by annealing a mixture of metal oxides and carbonates gradually up to 1000 degrees C in air, and characterized by XRPD, XPS, TPD, ...
Treatment of Escherichia coli O157:H7 with lactic acid, neutralized electrolyzed oxidizing water and chlorine dioxide followed by growth under sub-optimal conditions of temperature, pH and modified atmosphere
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
The utilization of sub-lethal decontamination treatments gains more and more interest due to the increased consumers' demand for fresh, minimally processed and convenient food products. These products rely on cold chain ...
