      Sarıer, Nihal; Önder, Emel; Ukuşer, Gökçen; Öztürk, Mehmet; Arat, Refik (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2013-08-20)
      This study investigates the intercalation of low molecular weight poly(ethylene glycol), PEG1000, into a montmorillonite-type Anatolian clay mineral (MMTA) using ultrasound sonication in a solvent free medium to produce a ...
    • VORTEX SHEDDINGS ON THE INSTABILITY AT SUBSEA SUSPENDED PIPELINE 

      Mastanzade, Nijat; Yılmaz, Levent (AMER SOC MECHANICAL ENGINEERS, THREE PARK AVENUE, NEW YORK, NY 10016-5990 USA, 2008)
      The underwater suspended pipeline was investigated for the lateral vibration which is applied for the oscillation of the pipeline part for vortex shedding. Firstly it is defined the tension force at the connection legs on ...
    • Water Runoff, sediment transport and related impacts in the Southeastern Black Sea rivers 

      Berkun, Mehmet; Aras, Egemen; Özel Akdemir, Ümmükülsüm (Gh Asachi Technical Univ Iasi, 71 Mangeron Blvd, Iasi, 700050, Romania, 2015-04)
      The Southeastern Black Sea coastal region in Turkey and Georgia is under threat of severe coastal erosion and shoreline recession. The main reason for this problem is the response of the coast to human activities. While ...
    • Wireless 3-Axis Accelerometer System for Measurement of Structural Displacement 

      Gürkan, Koray; Gürkan, Güray; Dindar, Ahmet Anıl; Akpınar, Burak; Gülal, Vahap Engin (IEEE, 345 E 47Th St, New York, Ny 10017 Usa, 2013)
      In this study, we present the design of a 3-axis acceleration measurement system that is capable of UTC (Coordinated Universal Time) time-stamping captured from a Global Positioning System (GPS) receiver module. With this ...
    • β-Carotene adsorption on acid-activated montmorillonite 

      Sarıer, Nihal; Güler, Çetin (1988-05)
      The adsorption of β-carotene from solution in benzene on acid-activated Canakkale montmorillonite of Turkey has been investigated. The adsorption isotherm had two steps. The first step was of the Langmuir type, and the ...
