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 ...
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, ...
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 ...
The adsorption of pharmaceutically active compounds from aqueous solutions onto activated carbons
(Elsevier Science Bv, Amsterdam, 2015)
In this study, the adsorption of pharmaceutically active compounds - salicylic acid, acetylsalicylic acid, atenolol and diclofenac-Na onto activated carbons has been studied. Three different commercial activated carbons, ...
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 ...
Uncertainty and modeling energy consumption: Sensitivity analysis for a city-scale domestic energy model
(Elsevier Science Sa, Lausanne, 2013)
This paper presents the development and evaluation of the Belgrade Domestic Energy Model (BEDEM) for predicting the energy consumption and carbon dioxide (CO2) emissions of the existing housing stock. The distribution of ...
The impact of storage on the primary and secondary metabolites, antioxidant activity and digestibility of oat grains (Avena sativa)
(Elsevier, Amsterdam, 2014)
The effect of storage was studied on grain metabolites, functional properties and digestibility of three oat cultivars selected in Serbia - Dunav, Vrbas and NS Tara. During the 12 and 24 months of storage, there was a ...
Chemical profile of major taste- and health-related compounds of Oblainska sour cherry
(Wiley, Hoboken, 2016)
BACKGROUND: Oblainska sour cherry, an autochthonous cultivar, is the most planted cultivar in Serbian commercial orchards. Owing to its long cultivation under different agro-ecological conditions, it is a mixture of different ...
Atmospheric processing of iron carried by mineral dust
(Copernicus Gesellschaft Mbh, Gottingen, 2013)
Nutrification of the open ocean originates mainly from deposited aerosol in which the bio-avaliable iron is likely to be an important factor. The relatively insoluble iron in dust from arid soils becomes more soluble after ...
Environmental assessment of heavy metals around the largest coal fired power plant in Serbia
(Elsevier Science Bv, Amsterdam, 2016)
Anthropogenic activities may lead to increased levels of heavy metals in soil environment and to reduced environmental quality. In this study concentrations of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn) were ...
