    • Intermediate-Term Variations İn Solar Radius During Solar Cycle 23 

      Gölbaşı, Orhan; Kılıç, H.; Chollet, F. (Wiley-V C H Verlag Gmbh, Po Box 10 11 61, D-69451 Weinheim, Germany, 2009-05)
      In this study, we look for the mid-term variations in the daily average data of solar radius measurements made at the Solar Astrolabe Station of TUBITAK National Observatory (TUG) during solar cycle 23 for a time interval ...
    • Sintering behavior of ZnO:Al ceramics fabricated by sol-gel derived nanocrystalline powders 

      Bahşi, Zehra Banu; Aslan, Muhammed Hasan; Özer, Mehmet; Oral, Ahmet Yavuz (Wiley-V C H Verlag Gmbh, Po Box 10 11 61, D-69451 Weinheim, Germany, 2009-09)
      ZnO:Al ceramics (Zn:Al, 0.95:0.05) were prepared by using sol-gel derived nanocrystalline powders. XRD patterns of the doped ceramics revealed the existence of both zincite (JCPDS 36-1451) and gahnite (JCPDS 5-0669) phases. ...
