In this study. Sr2P2O7 was doped with some rare earth oxides (Pr6O11, Nd2O3, Dy2O3, Ho2O3, Er2O3, and Tm2O3) at 0.5%, 1%, 2%, 3%, 4%, 5%, 10%, and 15% (by weight) and co-doped with CuO by heating at 900 C for 10 h. Structural analysis of the products was carried out by powder X-ray diffraction (XRD). XRD patterns of the samples showed that doping did not alter the orthorhombic structure of the Sr2P2O7. Thermoluminescence (TL) glow curve measurements were obtained and these showed that Pr and Cu-doped Sr2P2O7 exhibit very significant thermoluminescence glow peaks, suggesting these could be promising dosimetric materials. Bearing this in mind, some TL dosimetric properties of Sr2P2O7:Cu,Pr compounds are presented in this paper, confirming they are promising for this application.

Investigation of turbulence models used in automotive industry Taştan, Umur; Çetinkaya, Tahsin Ali; Department of Mechanical Engineering (2011) In this study; reliability and performance of turbulence models used in CFD softwares to determine the aerodynamics of passenger cars, are tested and compared. In the analyses, drag forces acting on the car, pressure and velocity distributions and wake flow patterns are determined by using several turbulence models with a commercial software Fluent. Calculated results compared to the experimental results given in the literature. It is observed that, turbulence models give relatively reliable results for det...
CO2 emissions of Turkish manufacturing industry: A decomposition analysis Akbostancı Özkazanç, Elif; Tunç, Gül İpek (2011-06-01) In this study. CO2 emissions of Turkish manufacturing industry are calculated by using the fuel consumption data at ISIC revision 2, four digit level. Study covers 57 industries, for the 1995-2001 period. Log Mean Divisia Index (LMDI) method is used to decompose the changes in the CO2 emissions of manufacturing industry into five components: changes in activity, activity structure, sectoral energy intensity, sectoral energy mix and emission factors. Mainly, it is found that changes in total industrial activ...
The Coastal circulation model of Büyük Menderes river mouth and adjacent coastal areas Gözlet, Mehmet Sedat; Özyurt Tarakcıoğlu, Gülizar; Baykal, Cüneyt; Department of Civil Engineering (2019) In this study; coastal circulation of Buyuk Menders river mouth and the adjacent coastal areas is modeled to determine the current characteristics of the region under river-sea interaction. For this purpose, Finite Volume Coastal Ocean Model (FVCOM) numerical model is setup and run under wind, tide, and river forcing conditions. Current, salinity, temperature data from field measurements are used to validate the performance of the model setup with default parametrization. Significance of each forcing on the...
Gas production from hydrate resevoirs Alp, Doruk; Parlaktuma, Mahmut; Department of Petroleum and Natural Gas Engineering (2005) In this study; gas production by depressurization method from a hydrate reservoir containing free gas zone below the hydrate zone is numerically modeled through 3 dimensional, 3 phase, non-isothermal reservoir simulation. The endothermic nature of hydrate decomposition requires modeling to be non-isothermal; hence energy balance equations must be employed in the simulation process. TOUGH-Fx, the successor of the well known multipurpose reservoir simulator TOUGH2 (Pruess [24]) and its very first module TOUGH...
