UZAKTAN ÇALIŞMANIN ESNEKLİĞİ: ÜÇÜNCÜ YER OLARAK KAHVE EVLERİ ANKARA ÇUKURAMBAR Çavdaroğlu, İbrahim; Yetişkul Şenbil, Emine; Department of City and Regional Planning (2024-12-4) This master’s thesis examines the utilization of coffee houses as third places for remote work, with a particular focus on the Çukurambar district of Ankara. According to Ray Oldenburg's definition of "Third Place," sites that are neither homes (the first place) nor businesses (the second place) but are necessary for social contact, leisure, and community involvement are called third places. Third places might be coffee houses, restaurants, cafés, bars, and taverns. These settings give a vital break from th...
PYROLYSIS OF POLYLACTIC ACID USING BIFUNCTIONAL CATALYST Sökmen, Uğur; Sezgi, Naime Aslı; Dilek Hacıhabiboğlu, Çerağ; Department of Chemical Engineering (2024-12-04) Polylactic acid is a promising polymer thanks to being biodegradable. PLA could be utilized to diminish environmental problems caused by non-biodegradable petroleum-based polymers. However, misconceptions about the biodegradability of PLA lead to PLA waste. Nature lacks the proper conditions, such as temperature, pH, etc., that PLA requires to decompose easily; therefore, PLA waste is inevitable. Thus, the aim of this study was to investigate PLA degradation using a catalyst. In this study support material ...
Psychosis From a Secondary Perspective: Contributions of Philosophy to the Practice of Psychiatry Oğuzman, Zeynep; Zambak, Aziz Fevzi; Department of Philosophy (2025-1) Traditional third-person symptom-based diagnostic-treatment methods do not adequately address the subjective experiences of psychotic patients; reductionist biopsychiatry fails to comprehensively assess subjective experiences and treatment difficulties. Alternatively, first-person perspective practices and the biopsychosocial model are also incompatible with the scientific paradigm and fail to identify diagnostic-treatment goals. Nevertheless, calls to address the shortcomings of first- and third-person per...
Failure Analysis of Curved Fiber Reinforced Composite Beam using State Based Peridynamics Haliloğlu Celiloğlu, Erhan; Çöker, Demirkan; Dördüncü, Mehmet; Department of Aerospace Engineering (2024-12-06) Composite materials are favored for their specific stiffness and strength properties in airframe design. However, benefits obtained in lightweight and tailored design fade due to complexity in material qualification and structural analyses in airframe design. To ensure the structural integrity of an airframe, series of tests are conducted to quantify mechanical properties and design allowables for failure which are used in stress analyses. Thus, simulating structural failures has many benefits in airframe d...
COMPUTATIONAL PARAMETRIC ANALYSES OF ENERGY ABSORPTION CAPACITIES OF DIFFERENT LATTICE STRUCTURES Karaca, İsmail Safa; Gürses, Ercan; Department of Aerospace Engineering (2024-12) In this thesis study, the energy absorption capacities of three different lattice structures were calculated depending on variable parameters. The three lattice structures were created using hexagonal, re-entrant, and chiral unit cells. Five different parametric studies were conducted for each model by making thickness changes, angle changes of unit cells, and adding elements to unit cells. The first study engendered changes in the thickness of the horizontal and vertical edges relative to each other while ...
The pressure effect on particle size distribution of recycling NdFeB magnets Özaltun, Gizem; Akdeniz, Mahmut Vedat; Çakır, Öznur; Department of Metallurgical and Materials Engineering (2024-12-5) Rare earth permanent magnets (REPMs), specifically NdFeB magnets, play a crucial role in industries due to their improved magnetic performance. However, sustainable alternatives, such as recycling, are needed, as there are significant geopolitical supply concerns regarding the dependence on rare earth elements (REEs), which are also included in the list of critical raw materials identified by the European Commission. The objective of this thesis is to investigate the impact of hydrogen pressure on scrap NdF...

Physico-chemical characterization of cement type hydration of alpha-tricalcium phosphate Köhnetarfun, Mehmet Yiğit; Durucan, Caner; Department of Metallurgical and Materials Engineering (2024-12-02) Synthetic bone grafts are widely employed in bone restoration procedures, particularly in the treatment of bone defects. Alpha-tricalcium phosphate (α-TCP, α-Ca₃(PO₄)₂) is a commonly utilized calcium orthophosphate material for bone filling applications. Upon hydration with aqueous solutions, α-TCP-based powder cement systems undergo a transformation into calcium-deficient hydroxyapatite (CDHAp, Ca₉(HPO₄)(PO₄)₅(OH)), a key inorganic component of bone tissue that plays a critical role in bone healing and def...

Beyond the State: Reframing Kemalism from Neo-Kemalism to Civic Atatürkism in Post-1980 Turkey Özdemir, Enes Utku; Aytekin, Erden Attila; Department of Political Science and Public Administration (2025-1-06) This thesis explores the evolution of Kemalism in post-1980 Turkey, concentrating on the rise of Civic Atatürkism from the Neo-Kemalism of the 1990s. It posits that Civic Atatürkism emerged as a response to the de-Kemalization of state institutions and the shortcomings of post-Kemalism, illustrating Turkey's identity negotiation through the reframing of Atatürk. Civic Atatürkism enables diverse actors to reinterpret and recontextualize Republican symbols, using them to advance varied agendas and prioritizin...
