A phase diagram near the NAC point in liquid crystals
(Elsevier Science SA, 2002-07-28)In this study using a mean field model we obtain the phase line equations for the NA. NC and AC transitions near the NAC point in a mixture of liquid crystals. We then fit these phase line equations to the experimental ... -
Yeşilırmak taraçalarında (Orta Kuzey Anadolu) geç pleyistosen iklim değişiklikleri ve düşey yönlü deformasyona akarsu cevabının araştırılması
(TMMOB Jeoloji Mühendisleri Odası, 2017)Fosilleşmiş taşkın ovası çökelleri olarak da tanımlanan akarsu taraça basamaklanması, akarsuların gelişim süreci üzerindeki iklim, kaide seviyesi ve genç tektonik etkinin analitik olarak belirlenmesi için önemli kayıtlar ... -
Tectonic and climatic controls on Quaternary fluvial processes and river terrace formation in a Mediterranean setting, the Goksu River, southern Turkey
(Cambridge University Press, 2019-03)Climate and tectonics effect the fluvial evolution of the Mediterranean Mut basin. The basin contains a river terrace staircase of 16 levels (T16-T1) ranging from 365 to 10m above the current Goksu River in its middle and ... -
Quaternary uplift of the northern margin of the Central Anatolian Plateau: New OSL dates of fluvial and delta-terrace deposits of the Kizilirmak River, Black Sea coast, Turkey
(Pergamon-Elsevier Science Ltd, 2018-12-01)We analysed the interplay between coastal uplift, sea level change in the Black Sea, and incision of the Kizilirmak River in northern Turkey. These processes have created multiple co-genetic fluvial and marine terrace ... -
