Testing the validity of purchasing power parity in alternative markets: Evidence from the fourier quantile unit root test
(Borsa İstanbul, 2020)
This study analyzes the long-run validity of purchasing power parity (PPP) in three types of market economies—developed, emerging, and frontier markets—using the Fourier quantile unit root test. The analyses are conducted ...
Ce/Sm co-doped hydroxyapatites: synthesis, characterization, and band structure calculation
(Springer, 2020)
In this paper, Ce/Sm co-doped hydroxyapatites (HAps) were synthesized by a wet chemical route. The amount of Ce was kept at constant at the value of at.% 0.4, and the second dopant of Sm was used at different amounts of ...
A new 3D segmentation approach using extreme learning machine algorithm and morphological operations
(Elsevier, 2020)
Segmentation is one of the most crucial steps of image processing. Because 3D images contain depth information, they have gradually gained importance for numerical systems in image analysis. In the present study, a new 3D ...
Analysis of thermoluminescence characteristics of a lithium disilicate glass ceramic using a nonlinear autoregressive with exogenous input model
(Wiley, 2020)
Dental ceramics because of their translucency exemplify the most biologically realistic restorative materials for aesthetic rehabilitation and can be used to estimate dose accumulated as a result of a nuclear accident or ...
Accumulation of trace elements in muscle, gill and liver of fish species (Capoeta umbla and Luciobarbus mystaceus) in the Tigris River (Turkey), and health risk assessment
(Elsevier, 2020)
Two fish species (Capoeta umbla and Luciobarbus mystaceus) were collected from the Tigris River (Turkey), and tissues (gill, muscle and liver) of fish samples were analyzed for Cd, As, Mn, Cr, Cu, Co and Ni using the ...
Phytochemical screening and antioxidant activity of Diospyros Lotus L. fruits grown in Turkey
(Acta Scientiarum Polonorum, 2020)
The present study aimed to analyze total ascorbic acid content (TAC), total phenolic content (TPC), total flavonoid content (TFC), phenolic composition, fatty acid profiles, and antioxidant activity of Diospyros lotus L. ...
Analyzing Biological Properties of Some Plum Genotypes Grown in Turkey
(Taylor & Francis, 2020)
In the current study, the biochemical components, antioxidant activity, antibacterial activity, and antimutagenic activity of 5 plum (Demal, White Cancur, Cancur, Red plum, and Sugar plum) fruits grown in Posof/Ardahan, ...
Comparison of biochemical, antimicrobial and cytotoxic activities of different propolis samples from Malatya and Bilecik
(Revista de Chimie SRL, 2020)
Propolis is a resinous natural mixtures collected and produced by honey bees. It is rich in essential oils and phenolic components so it has high levels of antioxidant, antimicrobial, anti-inflammatory and anti-tumoral ...
Synthesis of NiO/SnO2 nanowires for energy applications
(Polska Akademia Nauk, 2020)
In this study, SnO2 nanowire arrays with lengths in the micrometres range were successfully synthesised by using polyethylene glycol (PEG) at room temperature. Then Ni was coated onto the SnO2 nanowires by chemical ...
Some results on wijsman ideal convergence in intuitionistic fuzzy metric spaces
(Hindawi, 2020)
In the present work, we study and extend the notion of Wijsman J-convergence and Wijsman J*-convergence for the sequence of closed sets in a more general setting, i.e., in the intuitionistic fuzzy metric spaces (briefly, ...
