Bu çalışmada Çayca/Kütahya’dan alınan tüflerin çimentoda mineral katkı maddesi olarak kullanılabilirliği araştırılmıştır. Çayca tüfünün toplam SiO2+Al2O3+Fe2O3 içeriği %85.34’dür. volkanik birimleri riyodasitik tüf, dasitik andezitik tüf bileşimleridir. Kirli beyaz, sarımsı, grimsi, pembemsi ve bej renkler gösteren tüflerinin çok hızlı (10 saniyede 4476 cm2/g) öğütülebildiği görülmüştür. Farklı...
Using the surface brightness fluctuations in HST WFPC-2 images, we determine that M87, NGC 4486B, and NGC 4478 are all at a distance of ∼ 16 Mpc, while NGC 4476 lies in the background at ∼ 21 Mpc. We also examine the globular clusters of M87 using archived HST fields. We detect the bimodal color distribution, and find that the amplitude of the red peak relative to the blue peak is greatest near...
