Hydrogenic impurities in graded GaAs-(Ga,Al)As quantum-well wires in an electric field
(ELSEVIER SCIENCE BV, 2002)
The electric field dependence of polarizability and binding energy of shallow-donor impurities in graded quantum-well wires is calculated by a variational method and in the effective-mass approximation. We have considered ...
Effect of Inbreeding Depression on Growth and Fluctuating Asymmetry in Turkish Young Males
(WILEY-BLACKWELL, 2010)
This study sought to examine the effects of inbreeding on physical development and fluctuating asymmetry (FA). A total 144 male high-school students (mean age = 18.11 +/- 0.52) whose parents are first cousins (F = 0.125) ...
Audiological evaluation of hearing levels in patients diagnosed with migraine
(MEDKNOW PUBLICATIONS & MEDIA PVT LTD, 2015)
Introduction: Based on the hypothesis that neurovascular events involving in the pathophysiology of migraine can cause hearing loss by influencing blood flow of inner ear, it was aimed to determine whether migraine with ...
Tracheobronchial rupture: a considerable risk for young teenagers
(ELSEVIER SCI IRELAND LTD, 2002)
Tracheobronchial (TB) ruptures are ten times lower in children than in adults. Despite its rarity in the literature, we found that it is as common as in adults in our series. We investigated TB ruptures in childhood regarding ...
The measurement of the rotational deformities with computed tomography in femoral shaft fractures of the children treated with early spica cast
(ELSEVIER SCI IRELAND LTD, 2003)
Twenty-eight children with femoral shaft fractures, treated with early spica cast, were evaluated with computed tomography (CT), for their femoral shaft rotational deformities. The femoral torsion angles were measured on ...
Microstructure of boron nitride coated on nuclear fuels by plasma enhanced chemical vapor deposition
(ELSEVIER SCIENCE BV, 1998)
Three nuclear fuels, pure urania, 5% and 10% gadolinia containing fuels were coated with boron nitride to improve nuclear and physical properties. Coating was done by plasma enhanced chemical vapor deposition technique by ...
Research of the substituent effect on non-linear optical properties of bis (difluoroboron)-1,2-bis((1H-pyrrol-2-yl)methylene)hydrazine (BOPHY) derivatives: Molecular simulation analyses
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)
Modelling studies of bis(difluoroboron)-1,2-bis( (1H-pyrrol-2-yl)methylene)hydrazine (BOPHY) derivatives were completed at M06-2X/6-31+G(d) level in vacuo. Structural properties (geometric structure, bond lengths and ...
Spin-orbit interaction effects on the optical properties of quantum wires under the influence of in-plane magnetic fields
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2015)
In this work, we studied the effects of in-plane magnetic field and Rashba spin-orbit interaction on the intersubband optical absorption coefficients and changes in refractive index for transitions between the first two ...
On the spectrum and fine spectrum of the compact Rhaly operators
(INDIAN NAT SCI ACAD, 2003)
In 1989, Rhaly determined the spectrum of Rhaly operator R-a regarded as an operator on the Hilbert space I-2 normed by parallel to x parallel to = (Sigma(n) \ x(n) \(2))(1/2). It is the purpose of this paper to determine ...
The investigation of quantum efficiency constituents of InAs/AlSb/GaSb based N structure type-II SL photodetectors with InAlAs interface
(IOP PUBLISHING LTD, 2018)
We report on the optical properties of InAs/AlSb/GaSb based Type-II superlattice N-structure with p on n configuration. The detector structure is designed to operate in the mid wavelength infrared range with 50% cut-off ...
