Experimental determination and modeling of excess molar volumes, viscosities and refractive indices of the binary systems (pyridine+1-propanol,+1,2-propanediol,+1,3-propanediol, and plus glycerol). New UNIFAC-VISCO parameters determination
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
Densities, viscosities and refractive indices of four binary systems consisting of pyridine with mono-, di-, and three- hydroxyl alcohols (1-propanol, 1,2-propanediol, 1,3-propanediol, and glycerol) were measured at eight ...
Seasonal water pricing using meteorological data: case study of Belgrade
(Elsevier Sci Ltd, Oxford, 2013)
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 ...
Forced degradation study of torasemide: Characterization of its degradation products
(Taylor & Francis Inc, Philadelphia, 2013)
Torasemide was subjected to forced degradation studies. Stress conditions were varied concerning hydrolysis (acid, base, and neutral), oxidation, photolysis, and thermal degradation in order to identify the potential ...
Development of polycaprolactone scaffold with antibacterial activity by an integrated supercritical extraction and impregnation process
(Elsevier, 2013)
The present study is aimed to develop a process for production of functionalized scaffolds impregnated with natural compounds extracted from Patagonian Usnea lichen. A setup for an integrated supercritical CO2 extraction ...
PM10 emission forecasting using artificial neural networks and genetic algorithm input variable optimization
(Elsevier Science Bv, Amsterdam, 2013)
This paper describes the development of an artificial neural network (ANN) model for the forecasting of annual PM10 emissions at the national level, using widely available sustainability and economical/industrial parameters ...
Influence of different pre-treatment methods on isolation of extracts with strong antibacterial activity from lichen Usnea barbata using carbon dioxide as a solvent
(Elsevier, Amsterdam, 2013)
Multiplication and spreading of multiresistant pathogenic bacteria that cause fatal infections in humans and animals have boosted research on implementation of newer technologies for producing natural substances with strong ...
Modification of chitosan by zeolite A and adsorption of Bezactive Orange 16 from aqueous solution
(Composites: Part B: Engineering, 2013)
This study represents new material based on chitosan modified by zeolite A as adsorbent for anionic dye, using Bezactive Orange 16 as a model compound. Interactions between dye and chitosan/zeolite A film at initial ...
Antimicrobial viscose fabric prepared by treatment in DBD and subsequent deposition of silver and copper ions-Investigation of plasma aging effect
(Elsevier Science Sa, Lausanne, 2013)
In this work, the effect of dielectric barrier discharge (DBD) in ambient air on preparation of antimicrobial viscose fabric was studied. DBD plasma treatment was applied under constant discharge power and different exposure ...
Mathematical modeling of cross-linking monomer elution from resin-based dental composites
(Wiley-Blackwell, Hoboken, 2013)
Elution of potentially toxic substances, including monomers, from resin-based dental composites may affect the biocompatibility of these materials in clinical conditions. In addition to the amounts of eluted monomers, ...
Thermal, morphological and mechanical properties of ethyl vanillin immobilized in polyvinyl alcohol by electrospinning process
(Vilnus : Central and Eastern European Committee for Thermal Analysis and Calorimetry, 2013)
In this study, polyvinyl alcohol (PVA) nanofibers with ethyl vanillin as active compound were prepared using electrospinning technique. The final products of electrospinning process were in the form of films consist of ...
