Determination of natural radioactivity by gross alpha and beta measurements in tap waters in Rize province
(Springer, 2015)
The aim of the study to determine the level of gross alpha and beta activity concentrations in tap waters in dwellings of Rize province from North part of Turkey after 27 years from Chernobyl disaster. the activity ...
Radioactivity and heavy metal concentrations in various honey samples
(Scibulcom Ltd, 2015)
In this study, the contents of natural radionuclide K-40 and fission product Cs-137 in floral honey samples from Rize and some other cities in Turkey, were investigated. the results indicated that 80% of honey samples were ...
Comparative studies of CdS, CdS:Al, CdS:Na and CdS:(Al-Na) thin films prepared by spray pyrolysis
(Academic Press Ltd- Elsevier Science Ltd, 2015)
In the present study, the spray pyrolysis technique was used to prepare pure CdS, 4 at.% Al-doped CdS, 4 at.% Na-doped CdS and (4 at.% Al, 4 at.% Na)-co-doped CdS thin films. It was found from X-ray diffraction data that ...
Effect of adding on the critical current density and lateral levitation force of bulk
(Springer/Plenum Publishers, 2015)
We fabricated malic acid -added bulks by wet mixing and "Two-step solid state reaction method". the effects of adding malic acid on , behaviour and lateral levitation force features of bulk have been investigated. A ...
High-field pinning potential in YBCO films with nanoengineered pinning centres
(Springer, 2015)
Frequency-dependent AC susceptibility measurements have been used to estimate the critical current densities and pinning potential of two 1.1-mu m-thick YBCO films with nanoengineered pinning centres. the films were grown ...
The effect of magnetic field distribution and pole array on the vertical levitation force properties of HTS maglev systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2015)
In this paper, the levitation force measurements have been carried out by the magnetic force measurement system under both field-cooling and zero-field-cooling regimes, whereas the magnetic field distribution over the ...
Design and simulation of 31/2-cell superconducting gun cavity and beam dynamics studies of the SASE-FEL System at the Institute of Accelerator Technologies at Ankara University
(Elsevier Science Bv, 2015)
Design and simulation of a superconducting gun cavity with 31/2 cells have been studied in order to give the first push to the electron beam for the linear accelerating system at the Institute of Accelerator Technologies ...
Determination of tritium concentrations in humans before the development of a nuclear power plant in Turkey
(Taylor & Francis Ltd, 2015)
The most widely used method to determine the level of tritium in humans is testing urine. Tritium concentrations in urine samples of 100 persons aged 18-66 years selected randomly from a pilot region in Turkey were analysed. ...
Cu(In,Ga)(Se,Te)(2) pentenary thin films formed by reaction of precursor layers
(Elsevier Science Sa, 2015)
Sodium doped CuIn(1 - x) Ga-x(Se(1 - y) Te-y)(2) (CIGST) thin films were grown on Mo-coated soda lime glass substrates by a two-stage technique. the effects of Te content and annealing temperature on the microstructural ...
The size effect on the magnetic levitation force of MgB2 bulk superconductors
(Elsevier Sci Ltd, 2016)
In this study, the size effect on the magnetic levitation performance of disk-shaped MgB2 bulk superconductors and permanent magnets was investigated. MgB2 samples with varying diameters of 13 mm, 15 mm and 18 mm, each of ...
