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 ...

Disability in elderly patients with chronic neurological illness: Stroke, multiple sclerosis and epilepsy
(ELSEVIER IRELAND LTD, 2011)
The aim of the study was to evaluate disability in patients with elderly stroke, multiple sclerosis (MS) and epilepsy, and to analyze its relationship with demographic characteristics. We conducted a cross-sectional study ...
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 ...
Haptoglobin, serum amyloid A and ceruloplasmin concentrations in cattle with suspicion of coryza gangrenosa bovum
(UNIV ZAGREB VET FACULTY, 2017)
The aim of this study was to detemiine haptoglohin (Hp), serum amyloid-A (SAA) and ceruloplasmin (Cp) levels in naturally occurring cases of coryza gangrenosa bovum (CGB). The study was conducted on 14 animals, where 7 ...
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 ...
