Hydrogenic impurity states in zinc-blende InxGa1-xN/GaN in cylindrical quantum well wires
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
Within the framework of effective-mass approximation, the binding energy of a hydrogenic donor impurity in zinc-blende (ZB) InxGa1-xN/GaN cylindrical quantum well wires (CQWWs) is investigated using variational procedures. ...
Nonlinear optical properties of asymmetric double-graded quantum wells
(TAYLOR & FRANCIS LTD, 2018)
In this work, the effects of the structure parameters, such as the central barrier thickness and the aluminium concentrations x, on the linear and nonlinear intersubband optical absorption coefficients and refractive index ...

Serum levels of ET-1, M30, and angiopoietins-1 and-2 in HELLP syndrome and preeclampsia compared to controls
(SPRINGER HEIDELBERG, 2016)
We aimed to compare the serum levels of ET-1, M30, and Angs-1 and -2 in patients with preeclampsia or HELLP syndrome, and normal controls. In this cross-sectional study of 74 pregnant women, serum levels of ET-1, M30, and ...
Biological understanding of the cardiovascular risk associated with major depression and panic disorder is important
(TAYLOR & FRANCIS LTD, 2012)
Introduction. Panic disorder (PD) and major depressive disorders (MDD) are serious mental disorders but the mechanisms underlying the pathophysiology are poorly understood. Nitric oxide (NO) is a gas considered to play an ...
An optimization study of yield for a coal washing plant from Zonguldak region
(ELSEVIER SCIENCE BV, 2013)
In this study, a coal washing plant in Zonguldak was optimized using equalization of incremental product quality approach which maximizes plant yield for a given ash constraint based on float-sink data. By maximization of ...
