Comprehensive structural and optical characterization of AlAs/GaAs distributed Bragg reflector
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2019)
30-pair AlAs/GaAs distributed Bragg reflector (DBR), which has 1030 nm center reflectivity, is studied extensively by means of High Resolution X-ray Diffraction (HR-XRD) and reflectivity measurements. Theta/2-Theta ...
Effect of technology addiction on academic success and fatigue among Turkish university students
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2019)
Background: Technology addiction can cause certain physical, mental, and social health problems. Purpose: This study was conducted to determine the effect of technology addiction levels on academic success and fatigue in ...
Diagnostic Performance of Different Methods in Detecting Incipient Non-Cavitated Occlusal Caries Lesions in Permanent Teeth
(JOURNAL PEDODONTICS INC, 2019)
Aim: This in vitro study was aimed to investigate the performance of the new caries detection tools on the incipient occlusal caries. Study design: In our study, 100 permanent molar teeth, which were considered to have ...
SPECTRA AND FINE SPECTRA OF THE UPPER TRIANGULAR BAND MATRIX U(a; 0; b) OVER THE SEQUENCE SPACE C-0
(UNIV MISKOLC INST MATH, 2019)
The aim of this paper is to obtain the spectrum, fine spectrum, approximate point spectrum, defect spectrum and compression spectrum of the operator U(a;0;b) = [GRAPHICS] (b(0) , b(1) , b(2) not equal 0) on the sequence ...
The functionality of the external electric and magnetic field on optical specifications of Rosen-Morse quantum well
(IOP PUBLISHING LTD, 2019)
In this study, for the first time, we probe the influences of the external electric and magnetic field (EF and MF) on the total refractive index changes (TRICs) and the total absorption coefficients (TACs) of quantum well ...
Nonlinear optical properties of triple delta-doped quantum wells: The impact of the applied external fields
(ELSEVIER GMBH, 2019)
In the present paper, we theoretically investigate the effect of applied external fields, such as electric, magnetic, and intense terahertz laser fields on the optical absorption and the relative refractive index change ...
Determination of the block movements in the eastern section of the Gediz Graben (Turkey) from GNSS measurements
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)
The source parameters of an earthquake should be determined in detail to calculate deformations caused by that earthquake and to identify faults that are likely to break. Today, the GNSS method is frequently used to determine ...
A scale-development study: Exploration of intensive-care nurses' attitudes towards futile treatments
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2019)
The study was conducted to determine the validity and reliability of the tool used to assess nurses' attitudes towards futility, and to explore intensive-care nurses' attitudes towards futility. Principal components analysis ...
The contribution of AsH3: Pre-flow and V/III ratio effects on heteroepitaxially grown GaAs/Ge
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2019)
We report the effects of AsH3 (arsine) on morphological, structural, optical and crystalline quality of MOVPE (metal organic vapor phase epitaxy) grown GaAs/Ge heterostructures. AsH3 pre-flow supplied on Ge substrate to ...
Vortex assisted-ionic liquid dispersive liquid-liquid microextraction and spectrophotometric determination of quercetin in tea, honey, fruit juice and wine samples after optimization based on response surface methodology
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)
The aim of our study is to develop a new vortex assisted-ionic liquid dispersive liquid-liquid microextraction (VA-IL-DLLM ) method for preconcentration and determination of the quercetin in tea, honey, fruit juice and ...
