The Gulf of Iskenderun is one of the largest gulfs in the Eastern Mediterranean Sea. Particularly, it is the easternmost and third largest gulf in the southern Anatolian shoreline of Turkey. It contains the Miocene Iskenderun ...
Effect of magnetic fields on the linear and nonlinear intersubband optical absorption coefficients and refractive index changes in square and graded quantum wells
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
In this study, both the intersubband optical absorption coefficients and the refractive index changes as dependent on the magnetic field are calculated in square and graded quantum wells. Our results show that the position ...
On trace of symmetric bi-gamma-derivations in gamma-near-rings
(UNIV HOUSTON, 2007)
Let M be a 2-torsion free 3-prime left Gamma-near-ring with multiplicative center C. For x is an element of M, let C(x) be the centralizer of x in M. The aim of this paper is to study the trace of symmetric bi-Gamma-derivations ...
