The Magnetic and Structural Properties of SiC-Doped MgB2 Bulks Prepared by the Standard Ceramic Processing
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2011-01)
According to general formula MgB2-x SiC (x) (x=0,0.05,0.1,0.2), MgB2 and SiC-doped bulk superconductors were prepared by the standard ceramic processing. The mixtures of the corresponding powders were sintered at 750 degrees ...

Mathematical analysis of spark ignition engine via the combination of the first and second laws of thermodynamics
(Proceedings of Royal Society A-Mathematical Physical & Engineering Sciences (Royal Society Publishing), 2008)
This study aims at the theoretical exergetic evaluation of spark ignition engine operation. For this purpose, a two-zone quasi-dimensional cycle model was installed, not considering the complex calculation of fluid motions. ...
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 ...
