The aim of this study was to evaluate the psychometric validity and reliability Turkish version Questionnaire for Urinary Incontinence Diagnosis (QUID), which developed women with urinary incontinence. This cross-sectional, methodological included 600 female participants aged 18 years above reading writing skills. Psychometric methods comprised correlation analysis, internal consistency (Cronbach's alpha), test-retest reliability, receiver operating characteristic (ROC) curve analysis. QUID,...
Transmission of concentrated solar energy via fibre-optic bundle (FOB) has a great potential for numerous applications. In this paper, it is aimed to determine the transmission performance constructed plastical FOB-based lighting system. The experiments and measurements are carried out by means metal halide source simulating spectral distribution radiation in visible range wavelength. Optical efficiency, luminous efficacy, attenuation, characterization under different bending conditions,...
Abstract In this present study, the effects of electric, magnetic, and non-resonant intense laser field (ILF) on linear, third-order nonlinear, total optical absorption coefficients (TOACs) relative refractive index changes (RRICs) GaAs quantum well, having Hulthen confinement potential, were theoretically investigated. addition, dependence nonlinear properties in structure intensity incident photon inverse relaxation time was also calculated. To do research, firstly energy eigenvalues...
Abstract We have calculated the plasmon dispersion relations in a doped double quantum well with and without exchange–correlation potential added to effective of system. The calculations were done for high low doping densities by solving Schrödinger Poisson equations self‐consistently. Our numerical results show that is quite important at donor impurities dispersions large wave vectors. On other hand, ratio subband populations n i density N D more affected densities.

The luminous intensity unit and traceability in derived units of illuminance luminance were realized using new detector-based approach at the National Metrology Institute Turkey. Services photometry enlarged to perform high-level meter calibrations, namely levels up 5000 lx cd/m<sup>2</sup> by working standard photometer heads, precise apertures integrating spheres on 6 m long photometric bench. Working standart heads which consist a single silicon photodiode, V(λ)-corrected filter,...
Complete characterization of a filter radiometer, which is constructed from three-element reflection trap detector, temperature controlled band-pass filters and precision aperture, introduced. This study presents the progress made in primary level spectral irradiance measurements at National Metrology Institute (UME) Turkey.
Abstract In this paper, the effects of external electric, magnetic and non-resonant intense laser fields on nonlinear optical rectification (NOR), second-harmonic (SH), third-harmonic (TH) generation in a GaAs quantum well with asymmetrical Gaussian potential are theoretically investigated. Firstly, energy eigenvalues eigenfunctions single electron confined structure obtained by using diagonalization method within framework effective-mass parabolic band approaches. Then, these...
Bu çalışmada, GaAs /AlGaAs çoklu kuantum kuyusunun Akım-Voltaj ölçümlerinin sıcaklığa bağlılığını inceledik. Merkez bölgesinde 10 adet /Al_0.25 Ga_0.75 As kuyusu ile n^+-GaAs kontak tabakaları arasında eğimli tabakalardan oluşan örneğimiz, Metal Organik Buhar Fazlı Epitaksi tekniği büyütülmüştür. Tünelleme akımının düşük sıcaklıklarda (&lt;85 K) ve yüksek voltajlarda, termal akımın ise (&gt;125 voltajlarda etkili olduğu gözlemlendi. Ayrıca, ara sıcaklık (65 K
