The significance of periodic parameters for ANN modeling of daily SO2 and NOx concentrations: A case study of Belgrade, Serbia
(Turkish Natl Committee Air Pollution Res & Control-Tuncap, Buca, 2019)
In recent decades, artificial neural networks (ANNs) have been used for the prediction of concentration of air pollutants in urban areas. Beside meteorological variables, periodic parameters, such as hour of the day or ...
Hybrid denture acrylic composites with nanozirconia and electrospun polystyrene fibers
(Public Library Science, San Francisco, 2019)
The processing and characterization of hybrid PMMA resin composites with nano-zirconia (ZrO2) and electrospun polystyrene (PS) polymer fibers were presented in this study. Reinforcement was selected with the intention to ...
Novel engineering approach to optimization of thermal comfort properties of hemp containing textiles
(Taylor & Francis Ltd, Abingdon, 2019)
The aim of this research was to investigate the possibilities of producing comfort hemp containing textile fabrics by assembling a pure hemp yarn with other-fibre containing yarn. The plain knitted fabrics were produced ...
Synthesis, antimicrobial activity and quantum chemical investigation of novel succinimide derivatives
(Elsevier Science Bv, Amsterdam, 2019)
In the present study, twelve new 1-aryl-3-ethyl-3-methylpyrrolidine-2,5-diones were synthesized and their structures were characterized by FT-IR, H-1 NMR, C-13 NMR spectroscopy and elemental analysis. In the final step of ...
Theoretical and experimental investigation of geometry and stability of small potassium-iodide KnI (n=2-6) clusters
(Wiley, Hoboken, 2019)
Small heterogeneous potassium-iodide clusters are investigated by means of ab initio electronic structural methods together with experimental production and detection in mass spectrometry. Experiments were done by using ...
Novel Approach for Flavonoid Esters Production: Statistically Optimized Enzymatic Synthesis Using Natural Oils and Application in Cosmetics
(Amer Chemical Soc, Washington, 2019)
The present work describes application of natural triglycerides for lipase-catalyzed esterification of structurally diverse flavonoids-esculin, naringin, and phloridzin. Ester mixtures with laurate, linolenate, or linoleate ...
Molecular and Supra-Molecular Structural Ordering of Wheat Starch-OSA Modified Waxy Maize Starch Mixtures During Storage
(Wiley-VCH Verlag Gmbh, Weinheim, 2019)
The influence of waxy maize OSA starches on the retrogradation kinetics of wheat starch pastes is investigated using dynamic oscillatory rheological and differential scanning calorimetry (DSC) measurements. Total starch ...
Study on Transglucosylation Properties of Amylosucrase from Xanthomonas campestris pv. Campestris and Its Application in the Production of alpha-Arbutin
(MDPI, Basel, 2019)
alpha-Arbutin (4-hydroquinone-alpha-D-glucopyranoside), an effective skin-lightening agent due to its considerable inhibitory effect on human tyrosinase activity, is widely used in the pharmaceutical and cosmetic industries. ...
Color stability of bulk-fill and universal composite restorations with dissimilar dentin replacement materials
(Wiley, Hoboken, 2019)
Objective To determine color changes in bulk-fill composite and universal composite restorations with dissimilar dentin replacement materials in extracted teeth after staining in red wine. Materials and Methods Cylindrical, ...
Theorems of the Alternative for Systems of Convex Inequalities
(Springer, Dordrecht, 2019)
Systems of convex inequalities in function spaces are considered. Solvability conditions are obtained in the form of a theorem of the alternative. We revisit some results from the literature where such theorems are incorrect. ...
