The effect of partial Lu doping on magnetic behaviour of YBCO (123) superconductors
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2010-04-09)
We have investigated the effect of Lutetium doping on YBCO prepared by conventional solid-state reaction method by means of XRD, AC susceptibility and DC magnetization measurements and theoretical analysis. AC susceptibility ...

(The Turkish Online Journal of Educational Technology (TOJET), 2004-01)
Eğitim literatürümüzde hizmet içi eğitimle ilgili yürütülen bir çok araştırmanın sonuçları MEB tarafından fen ve fizik öğretmenleri için yeterli sayıda ve etkili hizmet içi eğitim kurslarının düzenlenmediğini, ayrıca merkezi ...
Effective atomic numbers and electron densities of CuGaSe2 semiconductor in the energy range 6-511 keV
(JOHN WILEY & SONS LTD, THE ATRIUM, SOUTHERN GATE, CHICHESTER PO19 8SQ, W SUSSEX, ENGLAND, 2008-09)
The effective atomic numbers and electron densities of the CuGaSe2 semiconductor were calculated at 29 different energies from 6.9 to 511.0 keV by using the measured mass attenuation coefficients. Also, the mass attenuation ...
The in situ natural radionuclide (238U,232Th and40K) concentrations in Gümüşhane granitoids: implications for radiological hazard levels of Gümüşhane city, northeast Turkey
(Elsevier, 2019-05-12)
We have carried out 48 in situ measurements on radioactivities of 238U, 232Th and 40K isotopes at the Gümüşhane granitoid plutons employing gamma-ray spectrometer with a NaI(Tl) scintillation detector. The radionuclide ...
Irreversibility Line and Flux Relaxation Bi:2223/Ag tape Prepared by CTFF Technique : H // c axis
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2010-04-29)
We have studied flux dynamics in Bi:2223/Ag tape prepared by the CTFF technique in the orientation of H//c axis. Irreversibility line (IL) of a Bi:2223/Ag tape has been determined from AC susceptibility and the DC magnetization ...

Measurment of L X-Ray Production Cross-Sections and Li Subshell Florescence Yields
(Journal of Electron Spectrometry And Related Phenomena, 2003-04-03)
Li (i=1, 2 and 3) X-ray production cross sections have been measured for 14 elements in the atomic number range 55≤Z≤81 at 15.73 keV. The values of Li subshell fluorescence yields (ω1, ω2 and ω3) have been determined using ...
A New Method to Compensate for Counting Losses due to System Dead Time
(Nuclear Instruments and Methods in Physics Research A, 2009-05-21)
Determination of count losses and pile-up pulse effects in quantitative and qualitative analysis became a vital step in various analyses. Therefore, compensating for counting losses is of importance. These counting losses ...
