137Cs and 40K activity concentration measurements and elemental analysis in lichen samples collected from the Giresun province of northeastern Turkey
(TAYLOR & FRANCIS LTD, 4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND, 2008-09-01)
About 21 years after the Chernobyl accident, (137)Cs and (40)K activity concentration measurements using gamma-ray spectroscopy and elemental analysis using energy dispersive X-ray spectroscopy were performed in five ...
Determination of indoor radon and soil radioactivity levels in Giresun, Turkey
(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2008-08)
Indoor radon survey and gamma activity measurements in soil samples were carried out in the Giresun province (Northeastern Turkey). The result of analysis of variance showed a relationship between indoor radon and radium ...
The Effect of Y2O3 Buffer Layer on the Magnetic Properties of Melt-Processed YBCO Superconductor
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2011-07)
In this study, two kinds of melt-processed YBCO samples (Y1050-1 and Y1050-2) grown on a buffer layer of Y(2)O(3) addition were fabricated. The compacted powders were located on a crucible with Y(2)O(3) powder freely poured ...
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 ...
Determination of rectangular stress block parameters for high performance concrete
(2003)
Despite so much research on high performance concrete, the properties of this concrete are not known as well as those of ordinary concrete. There have been a lot of equations, rules and suggestions in the codes which are ...
The effects of the fiber contents on the mechanic properties of the adobes
(Construction and Building Materials, 2008-03)
In this study, compression and tensile tests were conducted for five different adobe mixtures. The important part of this study consisted of uniaxial compressive tests done with natural fiber mixtures. Thus, the results ...
Effects of Sintering Temperature on Microstructure and Magnetic Properties of Nd–Fe–B Magnets
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2013-05)
The sintered Nd-Fe-B (neodymium-iron-boron) magnet has been used for many applications in various fields such as acoustics, communications, and automation due to its excellent properties including high remanence, high ...
