Spatial sensitivity of seismic hazard results to background seismic activity models
Yilmaz, N.; Yücemen, Mehmet Semih (2011-08-04)
In the probabilistic seismic hazard analysis, the past earthquake records that can not be associated with any one of the specific faults are treated as background seismic activity. Contribution of background seismic activity to seismic hazard is generally calculated by using two different models, namely: background area source with uniform seismicity and spatially smoothed seismicity model. In this study, two case studies are carried out for a large (a country) and a small region (a province) in order to in...

Corrosion behaviors of stainless steels in molten zinc aluminum alloy
Özcan, Emre; Sevinç, Naci; Department of Metallurgical and Materials Engineering (2012)
High grade galvanized steel in large amounts is needed to match the increasing demand of automotive industry both in our country and in the world. Stainless steels, used in fabrication of zinc bath hardware of continuous galvanizing lines, lose their corrosion resistance due to various mechanisms in such mediums containing molten metals like zinc and aluminum. Consequently they corrode to the levels where they should be taken to maintenance or replaced. In this study, corrosion performance and the effect of...
Terahertz spectroscopy of dicyanobenzenes: Anomalous absorption intensities and spectral calculations
Esentürk, Okan; Heilweil, E. J. (2007-07-06)
Terahertz absorption spectra of three isomeric structures of dicyanobenzene in chloroform solution and solid phase at 298 K are reported. These spectra exhibit enhanced absorption in low THz range compared to most organic systems because of strong coupling to phonon modes. Molecular vibrational spectral calculations show strong correlation with the experiment especially for solution spectra. All intramolecular modes were assigned and intermolecular modes identified. Out-of-plane intramolecular modes at low ...
Sol-gel processing of silver-doped silica and assessment of its structural and antimicrobial properties
Akköprü Akgün, Betül; Durucan, Caner; Department of Metallurgical and Materials Engineering (2015)
Sol-gel processing routes for development of silver biocide-doped antibacterial silicate based coatings and powders were established and structural properties defining the antibacterial activity and long term durability were determined. During the first phase of this study, silver-doped silica based powders have been synthesized by hydrolysis and condensation of tetraethyl orthosilicate (TEOS, Si(OC2H5)4) in the presence of a silver nitrate (AgNO3) solution. The effects of modifications in sol-gel chemistry...
