Separation of phytochemicals from Helichrysum italicum: An analysis of different isolation techniques and biological activity of prepared extracts
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Helichrysum italicum presents a valuable source of natural bioactive compounds. In this work, a literature review of terpenes, phenolic compounds, and other less common phytochemicals from H. italicum with regard to ...
A linear and non-linear polynomial neural network modeling of dissolved oxygen content in surface water: Inter- and extrapolation performance with inputs' significance analysis
(Elsevier Science Bv, Amsterdam, 2018)
Accurate prediction of water quality parameters (WQPs) is an important task in the management of water resources. Artificial neural networks (ANNs) are frequently applied for dissolved oxygen (DO) prediction, but often ...
Effect of compositional data in the multivariate analysis of sterol concentrations in river sediments
(Elsevier Science Bv, Amsterdam, 2018)
In this paper, multivariate analysis of sterol concentrations detected in river sediment samples was performed. In order to remove co-dependence of values, concentrations of sterols were transformed using centered log-ratio ...
Effect of LCF on behavior and microstructure of microalloyed HSLA steel and its simulated CGHAZ
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Numerous structural components made of high strength low-alloyed steels are often exposed to low-cycle fatigue loading during their exploitation life. In order to study the fatigue behavior of one grade of structural steels ...
RuOx nanoparticles deposited on TiO2 nanotube arrays by ion-exchange method as electrocatalysts for the hydrogen evolution reaction in acid solution
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Nanocomposite cathodes for the hydrogen evolution reaction (HER) were prepared by deposition of RuOx catalyst particles on self-organized titania nanotube (TiNT) arrays of highly developed surface area, following a procedure ...
Estimation of residual strength of a crack-containing welded pressure vessel exposed to a subzero operating temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
This paper presents a method for estimating the residual-strength of welded pressure vessel made of HSLA steel which contains a surface axial crack. In order to analyze the behavior of the structure, a set of specimens ...
Bioflavour production from orange peel hydrolysate using immobilized Saccharomyces cerevisiae
(Springer, New York, 2013)
The rising trend of bioflavour synthesis by microorganisms is hindered by the high manufacturing costs, partially attributed to the cost of the starting material. To overcome this limitation, in the present study, dilute-acid ...
Densities and derived thermodynamic properties for the (n-heptane plus n-octane), (n-heptane plus ethanol) and (n-octane plus ethanol) systems at high pressures
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
This work reports densities for the pure n-heptane, n-octane and ethanol at temperatures from (288.15 to 413.15) K and at pressures up to 60 MPa. The same properties were determined for the binary mixtures n-heptane + ...
Characterization of silver/polystyrene nanocomposites prepared by in situ bulk radical polymerization
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Nanocomposites (NCs) with different content of silver nanoparticles (Ag NPs) embeded in polystyrene (PS) matrix were prepared by in situ bulk radical polymerization. The nearly monodisperse Ag NPs protected with oleylamine ...
Modeling analysis of the lipid bilayer-cytoskeleton coupling in erythrocyte membrane
(Springer Heidelberg, Heidelberg, 2014)
Studies of thermal fluctuations in discocytes, echinocytes, and spherocytes suggest that the coupling between lipid bilayer and cytoskeleton can affect viscoelastic behavior of single erythrocyte membranes. To test this ...
