Monte Carlo simulations and forecasting of Radium-226, Thorium-232, and Potassium-40 radioactivity concentrations
(Springer, 2020)
This study depicts the radioactivity time series levels of Ra-226, Th-232, and K-40 prospectively by Monte Carlo simulations (MCSs). Three ARIMA stationary stochastic processes are used with measurement records statistical ...
Synthesis, characterization, and swelling behavior of poly(N-hydroxymethylacrylamide) grafted poly(vinyl alcohol)
(Wiley, 2020)
In this study, the graft copolymerization of N-hydroxymethylacrylamide (NHMAAm) with poly(vinyl alcohol) (PVA) was carried out by using potassium persulfate/N,N,N,N-tetramethylethylenediamine (K2S2O8) to improve physicochemical ...
The effect of chewing gum on dry mouth, interdialytic weight gain, and intradialytic symptoms: A prospective, randomized controlled trial
(Wiley, 2021)
Introduction The major salivary glands can be stimulated by chewing gum to increase saliva flow and decrease xerostomia. The aim of this study was to investigate the effect of chewing gum on dry mouth, interdialytic weight ...
Significant role of the specific prime number p = 257 in the improvement of cryptosystems
(Bulgarian Acad Science, 2020)
Cryptology is the significant science which is inseparable from the means of communication of secrets. In a safe manner, it has the main objective of transmitting (potentially sensitive) information between two interlocutors. ...
Oxygen Vacancies in the Single Layer of Ti(2)CO(2)MXene: Effects of Gating Voltage, Mechanical Strain, and Atomic Impurities
(Wiley-V C H Verlag Gmbh, 2020)
Herein, using first-principles calculations the structural and electronic properties of the Ti(2)CO(2)MXene monolayer with and without oxygen vacancies are systematically investigated with different defect concentrations ...
A TYCHONOFF THEOREM FOR GRADED DITOPOLOGICAL TEXTURE SPACES
(Ankara Univ, Fac Sci, 2020)
In this paper, initial and product graded ditopologies are formulated and accordingly it is shown that dfGDitop is a topological structure over dffex x dffex. By means of spectrum idea, (di)compactness in graded ditological ...
Forced vibration analysis of composite-geometrically exact elliptical cone helices via mixed FEM
(Taylor & Francis Inc, 2020)
In this pioneering study, the cross-sectional warping included transient response and normal/shear stress components of composite elliptical and elliptical cone helices over exact axis geometry are investigated using a ...
Strain and electric field tuning of semi-metallic character WCrCO2 MXenes with dual narrow band gap
(Iop Publishing Ltd, 2020)
Motivated by the recent successful synthesis of double-M carbides, we investigate structural and electronic properties of WCrC and WCrCO2 monolayers and the effects of biaxial and out-of-plane strain and electric field ...
A 5-D Multi-Stable Hyperchaotic Two-Disk Dynamo System With No Equilibrium Point: Circuit Design, FPGA Realization and Applications to TRNGs and Image Encryption
(Ieee-Inst Electrical Electronics Engineers Inc, 2021)
In this work, we devise a new 5-D hyperchaotic dynamo system by adding two feedback controllers to the Rikitake 2-disk dynamo system (1958). We show that the new 5-D hyperchaotic system does not possess any equilibrium ...
Evaluation of students' scientific process skills through reflective worksheets in the inquiry-based learning environments
(Routledge Journals, Taylor & Francis Ltd, 2020)
This study aimed to evaluate how 7th-grade students' scientific process skills changed in the inquiry-based learning environment through reflective worksheets. For this purpose, four inquiry-based activities related to ...
