Positive Matrix Factorization (PMF) using particle bound organic compounds as tracers is applied to determine the primary source contributions to PM2.5 phase atmospheric particulate matter in Ankara to identify the seasonal variability of these compounds concentrations. Source contributions to fine particulate matter collected from urban and sub-urban sites in Ankara during July 2014 and September 2015 are calculated and prepared for this study. PAH compounds in daily collected samples at each site are determined and quantified by GC/MS and then are used as tracers in PMF model. The optimum result for both stations with PMF was obtained with 6 factors. Urban station factor distributions were 12, 11,9, 21,1, 25,3, 14,4 and 15,3 % respectively with diesel emissions, pyrogenic sources, biomass burning, petroleum emissions, domestic heating emissions and coal burning; for sub-urban station factor distributions were 21, 22, 13, 14, 17 and 13 % respectively with petroleum emissions, coal burning, pyrogenic sources, domestic heatingemissions, diesel emissions and traffic mix were defined

Multiscale pore structure characterization and pore network modeling of middle east carbonates Gündoğar, Satı Aslı; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2017) The complex interplay between structural and wettability heterogeneities is responsible for the limited pore network modeling studies on carbonates. In this study, our purpose is to develop structurally representative pore networks of Middle East carbonates and to predict their macroscopic difficult-to-measure relative permeability and capillary pressure hysteresis curves and residual oil trends under mixed-wettability conditions. In comparison with the conventional pore-scale models, particular emphasis is...
Geotechnical characterization and rock mass classification of the Antalya karstic rock masses Sopacı, Evrim; Akgün, Haluk; Department of Geological Engineering (2012) This thesis identifies the geotechnical parameters of the Antalya karstic foundation rocks (travertine/tufa), which are highly variable in nature, by means of geological observations, geotechnical site investigations, and field and laboratory geomechanics tests to examine karstic (mainly tufa) rock mass behavior. Several geotechnical parameters such as porosity, seismic wave velocity, uniaxial compressive strength, Young’s modulus, tensile strength, etc. that are thought to have significant influence on roc...
AN EXPERIMENTAL INVESTIGATION OF POSSIBLE PRODUCTION MECHANISMS OF HYDRATE FORMATION Engüçlü, Hasan Hüseyin; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2021-9-10) In this study, temperature, pressure and mole values of methane hydrate formation and dissociation are analyzed using different production methods under laboratory conditions. During the experiments, a cylindrical high-pressure hydrate cell in a constant temperature room was used. In order to provide the real field conditions of the hydrate reservoirs, methane gas was injected at high pressure into the cell filled with sand and water at low temperatures, and the hydrate reservoir was formed in a 21.2 *liter...
Chemical expansion in manganites Şeren, Mehmet Hazar; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2015) Manganites are type of manganese oxides having mixed valence states with perovskite structure represented as Ln1-xAxMnO3 (Ln= rare-earth cation, A= alkaline earth cation) and they have been widely studied due to their potential applications in various important areas and their interesting properties. Numerous investigations have focused on their production, characterization of their properties and solution of problems encountered during their applications. Some of these applications are cathode and electrol...
Niobium-Cobalt co-doped Barium Titanate Dielectric Ceramics for Multilayered Ceramic Capacitors Özgür, Berkay; Öztürk, Abdullah; Department of Metallurgical and Materials Engineering (2022-8-22) Niobium (Nb) and Cobalt (Co) co-doped barium titanate ceramics were prepared to stabilize ferroelectric-tetragonal phase transformation of barium titanate. Preparation of ceramics started with mixing barium titanate, niobium oxide and cobalt oxide powders at predetermined concentrations varying from 1 to 3 at%. The mixing was done at wet conditions using distilled water with alumina balls at 50 rpm for 24 h in a ball mill. Then, the mixtures were compacted into 15 mm diameter and 3 mm thick disc shaped pell...
