The effect of disorder on integer quantized Hall effect
(Elsevier, 2012)We study the effects of disorder on the integer quantized Hall effect within the screening theory, systematically. The disorder potential is analyzed considering the range of the potential fluctuations. The short-range ... -
Preparation and characterization of acrylonitrile-ethyl methacrylate copolymers and the effect of LiClO4 salt on electrical properties of copolymer films
(Wiley, 2012)Copolymers of poly(acrylonitrile-co-ethyl methacrylate), P(AN-EMA), with three different EMA content and parent homopolymers were synthesized by emulsion polymerization. The chemical composition of copolymers were identified ... -
Screening theory based modeling of the quantum Hall based quasi-particle interferometers, defined at quantum dots
(Elsevier Science Bv, 2012)In this work, we investigate the spatial distributions and the widths of the incompressible strips, i.e. the edge-states. The incompressible strips that correspond to nu = 1,2 and 1/3 filling factors are examined in the ... -
On the solutions of a class of nonlinear ordinary differential equations by the Bessel polynomials
(Walter de Gruyter & Co, 2012)In this study, we suggest a collocation method to solve a class of the nonlinear differential equations under the mixed conditions in terms of the Bessel polynomials. The method is based on the matrix forms of the Bessel ... -
Effects of manganese on the microstructure and dynamic precipitation in creep-resistant cast Mg-Ce-Mn alloys
(Pergamon-Elsevier Science Ltd, 2012)The creep-strengthening effect of Mn in Mg-Ce alloys has been studied via creep testing and transmission electron microscopy. It appears that alpha-Mn precipitates may serve as nucleants for the intradendritic heterogeneous ... -
Middle School Science and Items of High School Entrance Examination: Examining the Gap in Turkey
(Amer Soc Testing Materials, 2012)This study presents findings from an analysis of the Turkish Science and Technology Curriculum Guidelines and their alignment to the university entrance examination. The analysis of the Science and Technology Curriculum ... -
Poly(3-hydroxyalkanoate)s: Diversification and biomedical applications A state of the art review
(Elsevier, 2012)Biomaterials have played an important role in the treatment of disease and the improvement of health care. Synthetic and naturally occurring biodegradable and biocompatible polymers have been used as biomaterials. ... -
Quantitative performance measurements of bent crystal Laue analyzers for X-ray fluorescence spectroscopy
(Wiley-Blackwell, 2012)Third-generation synchrotron radiation sources pose difficult challenges for energy-dispersive detectors for XAFS because of their count rate limitations. One solution to this problem is the bent crystal Laue analyzer ... -
Synthesis and G-quadruplex binding study of a novel full visible absorbing perylene diimide dye
(Elsevier Science Sa, 2012)A novel perylene diimide dye containing glucopyranosyl groups in 1- and 7-positions of the perylene ring has been synthesized and characterized to obtain highly efficient and stable photosensitized material in photodynamic ... -
Personal and professional values grading among midwifery students
(Sage Publications Ltd, 2012)The purpose of this study was to determine the professional and personal values among midwifery students in Turkey and to identify whether the years of study affected these values. A total of 192 participants were asked ... -
Numerical analyses of piles subjected to lateral soil movement
(Korean Society of Civil Engineers-Ksce, 2012)Load transfer to piles due to the relative movement between the piles and the moving soil is a fairly complex soil-pile interaction problem. Different analysis methods are available in literature to estimate the loads on ... -
On the solutions of a system of linear retarded and advanced differential equations by the Bessel collocation approximation
(Pergamon-Elsevier Science Ltd, 2012)In this study, we present a numerical approximation for the solutions of the system of high-order linear retarded and advanced differential equations with variable coefficients under the mixed conditions. This method is ... -
Perylene Monolayer Protected Gold Nanorods: Unique Optical, Electronic Properties and Self-Assemblies
(Amer Chemical Soc, 2012)Here we report the synthesis and characterization of organosoluble perylene monolayer protected gold nanorods. From H-1 NMR, FT-IR, and differential scanning calorimetry experiments, the successful thiol exchange and ... -
Structural, spectral, electrochemical and catalytic reactivity studies of a series of N2O2 chelated palladium(II) complexes
(Pergamon-Elsevier Science Ltd, 2012)A series of neutral salicylaldiminato Pd(II) complexes have been synthesized and characterized. Spectral and electrochemical properties of the complexes in the solution phase have been investigated. The structure of complex ... -
The illustrated brief application of defect distribution model for heterojunction device by admittance spectroscopy
(Elsevier Science Sa, 2012)The dielectric properties of the devices can be studied by using admittance spectroscopy (AS). Majority carrier traps are experimentally analyzed without sophisticated mathematical manipulation. Experimental evidence ... -
A Taylor polynomial approach for solving the most general linear Fredholm integro-differential-difference equations
(Wiley, 2012)In this study, a matrix method is developed to solve approximately the most general higher order linear Fredholm integro-differential-difference equations with variable coefficients under the mixed conditions in terms of ... -
A numerical scheme for solutions of the Chen system
(Wiley-Blackwell, 2012)In this paper, we will develop the Bessel collocation method to find approximate solutions of the Chen system, which is a three-dimensional system of ODEs with quadratic nonlinearities. This scheme consists of reducing the ... -
Advance and Immediate Request Admission: A Preemptable Service Definition for Bandwidth Brokers
(Ccc Publ-Agora Univ, 2012)Differentiated Services Architecture lacks control level functionalities and Bandwidth Brokers are proposed to fill that gap. In order to provide proper control level functionalities, Bandwidth Brokers need to provide ... -
Genetic characterization of Meloidogyne incognita isolates from Turkey using sequence-related amplified polymorphism (SRAP)
(Versita, 2012)Southern root knot nematode Meloidogyne incognita is the most widespread-species, causing serious yield losses in protected vegetables fields in the West Mediterranean region of Turkey. The knowledge of genetic variation ... -
Repeat prostate biopsy: who, when, how?
