Öğe Edge state distribution in an Aharonov-Bohm electron interferometer in the integer quantum Hall regime(IOP PUBLISHING LTD, 2011) Ozturk, T.; Kavruk, A. E.; Ozturk, A.; Atav, U.; Yuksel, H.In this study we analyze the density distributions of the two dimensional electron system for an experimental geometry which is topologically equivalent of an Aharonov-Bohm interferometer in three dimensions in the quantum Hall regime and obtain the spatial distribution of the edge states. We employ the Thomas-Fermi approximation in our analysis and solve the Poisson equation in three dimensional using a multi grid technique. Also we obtain the distribution of incompressible strips for a wide range of magnetic fields strengths and comment on their relation with experimental results in literature.Öğe EFFECT OF SUPPLEMENTATION OF OVINE OVIDUCTAL CELLS WITH LH AND OESTRADIOL-17 beta ON EMBRYO DEVELOPMENT(INDIAN VETERINARY JOURNAL, 2008) Ciftci, H. B.; Zulkadir, U.; Boztepe, S.; Ozturk, A.; Dag, B.; Yetisir, R.In sheep, towards the end of follicular phase of the oestrus cycle, plasma concentration of E 2 increases and this increase is followed by an increase in LH secretion. The secretion of E 2 and LH can affect the secretary function of the oviductal cells and hence facilitate embryonic development in vitro. Therefore, the aim of this study was to measure the effect of supplementing the oviductal cells with Luteinizing Hormone,(LH) and oestradiol 17 beta (E(2)) on embryo development.Öğe EFFECTS OF UROLOGY SPECIALISTS AND RESIDENTS OF DIFFERENT LEVELS OF EXPERIENCE TO PNL RESULTS(ELSEVIER SCIENCE BV, 2011) Guven, S.; Ozturk, A.; Gurbuz, R.; Goger, E.; Kaynar, M.; Ardic, M.; Kilinc, M.[Abstract not Available]Öğe The self-consistent calculation of the edge states in bilayer quantum Hall bar(IOP PUBLISHING LTD, 2011) Kavruk, A. E.; Ozturk, T.; Ozturk, A.; Atav, U.; Yuksel, H.In this study, we present the spatial distributions of the edge channels for each layer in bilayer quantum Hall bar geometry for a wide range of applied magnetic fields. For this purpose, we employ a self-consistent Thomas-Fermi-Poisson approach to obtain the electron density distributions and related screened potential distributions. In order to have a more realistic description of the system we solve three dimensional Poisson equation numerically in each iteration step to obtain self consistency in the Thomas-Fermi-Poisson approach instead of employing a "frozen gate" approximation.Öğe TOTALLY TUBELESS PERCUTANEOUS NEPHROLITHOTOMY: IS IT SAFE AND EFFECTIVE IN PRESCHOOL CHILDREN? -- 2(MARY ANN LIEBERT INC, 2010) Guven, S.; Ozturk, A.; Kilinc, M.; Topbas, E.; Piskin, M.; Arslan, M.[Abstract not Available]
