Investigation of fluid rheology effects on ultrasound propagation
Özkök, Ozan; Uludağ, Yusuf; Department of Chemical Engineering (2012)
In this study, a mathematical model is developed for investigating the discrete sound propagation in viscoelastic medium to identify its viscoelastic properties. The outcome of the model suggests that pulse repetition frequency is a very important parameter for the determination of relaxation time. Adjusting the order of magnitude of the pulse repetition frequency, the corresponding relaxation time which has similar magnitude with pulse repetition frequency is filtered while the others in the spectrum are d...
Value assessment for industrial heritage in Zonguldak
Kılınç, Ayşem; Özgönül, Nimet; Restoration in Department of Architecture (2009)
The aim of this thesis is to develop a value assessment method for industrial heritage in Zonguldak, one of the symbolic industrial cities in Turkey where mining has been the leading force since the discovery of hard coal in the mid-19th century. Values to decide what to conserve and why are searched during this process under the light of discussions on industrial heritage and values of the architectural conservation. Focusing on this aim, this study is structured in four parts as the survey on industrializ...

Design and construction of double promoter systems and their use in pharmaceutical protein production in P. Pastoris
Demir, İrem; Çalık, Pınar; Department of Chemical Engineering (2019)
Intracellular phenomena such as promoter strength, mRNA secondary structure, translation efficiency and codon preference, 5′-untranslated region processing, and protein turnover, have impacts directly on the expression of heterologous genes. Design of multi-promoter expression systems with constituent strong promoters and engineered promoter variants is a novel metabolic engineering strategy for increasing the promoter strength further, and tuning the expression for recombinant protein (r-protein) productio...
Investigation of Stockbridge dampers for vibration control of overhead transmission lines
Kasap, Hüseyin; Özgen, Gökhan Osman; Department of Mechanical Engineering (2012)
This thesis aims to examine the performance of Stockbridge dampers used to suppress aeolian vibrations on overhead transmission lines arising from the wind. In this respect, a computer program, based on the Energy Balance Method, is developed using MATLAB. The developed computer program has also a graphical user interface (GUI), which allows the program to interactively simulate Stockbridge damper performance for vibration control of overhead transmission lines. Field tests results obtained from literature ...
