Publication Metadata only “And in the soup kitchen food shall be cooked twice every day”: gustatory aspects of Ottoman mosque complexes(Taylor and Francis, 2016) Department of Archeology and History of Art; Ergin, Nina Macaraig; Faculty Member; Department of Archeology and History of Art; College of Social Sciences and HumanitiesN/APublication Metadata only “Das recht auf vergessen" im rahmen des schutzes personenbezogener daten und die beurteilung in bezug auf die Türkei(İstanbul Kültür Üniversitesi, 2017) N/A; N/A; Önok, Rıfat Murat; Faculty Member; Law School; 178418Das “Recht auf Vergessen” hat in den letzten Jahren in der internationalen Literatur an Popularität gewonnen. Die Zahl der wissenschaftlichen Studien zu diesem Thema nimmt rasch zu. Wir sind jedoch weit entfernt davon, einen Konsens in der Lehre über die Grundlage dieses Rechts, sein Zweck und noch wichtiger über sein Inhalt und Umfang zu erzielen. Nach der Google-Entscheidung des EuGH, das hinsichtlich der Existenz (oder Nichtexistenz) eines solchen Rechts eine neue Dimension aufwirft und in Bezug auf Individuen an Bedeutung gewinnt, ist es nunmehr notwendig, das Recht auf Vergessen unter die Lupe zu nehmen. Es fällt auf, dass auch der “Yargıtay” damit begonnen hat, dieses Recht in seinen Entscheidungen zu nennen. In diesem Zusammenhang werden in diesem Aufsatz die Begriffsbestimmung, streitige Fragen in Bezug auf den Inhalt dieses Rechts, die Verbindung und Folgen der Google-Entscheidung mit diesem Recht, sowohl theoretische als auch praktische Fragen, die sich aus dem EUGH-Urteil und der Umsetzung eines solchen Rechts ergeben können, sowie eine Reihe von Fragen, die sich im Zusammenhang mit diesem Recht für die Türkei ergeben können untersucht. / Son yıllarda uluslararası literatürde popülarite kazanan kavramlardan biri“unutulma hakkı”dır. Konuya dair akademik çalışmaların sayısı hızla artmakla birlikte;hakkın dayanağı, hizmet ettiği amacı ve daha da önemlisi, tam içeriği ve kapsamı hakkın-da doktrinde görüş birliği sağlanmasına henüz uzağız. Buna rağmen, böyle bir hakkınvarlığının (veya yokluğunun) bireyler açısından önemi ve konuya yeni bir boyut kazandı-ran, Avrupa Birliği Adalet Divanı’nın Google kararı sonrasında, unutulma hakkının irde-lenmesi zorunluluk arz etmektedir. Yargıtay’ımızın da kararlarında kavrama yer vermeyebaşladığı dikkati çekmektedir. Bu bağlamda, çalışmada; kavramın tanımı, içeriğine dairtartışmalı hususlar, Google kararının bu hakla bağlantısı ve sonuçları, gerek ABAD kara-rından gerekse böyle bir hakkın uygulanmasından kaynaklanabilecek teorik ve pratiksorunlar, Türkiye açısından bu hakla bağlantılı birtakım meseleler incelenmiştir.Publication Metadata only “O/F shift” in hybrid rockets(American Institute of Aeronautics and Astronautics, 2014) Toson, Elena; Evans, Brian; Department of Mechanical Engineering; Karabeyoğlu, Mustafa Arif; Faculty Member; Department of Mechanical Engineering; College of Engineering; 114595For most hybrid rocket systems, oxidizer to fuel ratio (O/F) changes over time due to 1) natural growth of the fuel port diameter and 2) oxidizer flow rate variations, if throttling is employed. This phenomenon, which is referred to as “O/F shift”, leads to a reduction in motor performance. Note that liquid or solid rocket motors are not subject to temporal O/F variations, which is wrongfully considered as one of the most critical disadvantages of hybrid rockets. In this paper, the effect of “O/F shift” is quantified for hybrid rocket motors. Analytical formulas for the temporal O/F variation and the overall c* efficiency drop associated with the variation has been derived for single circular port motors. It has been shown that for a typical motor, c* efficiency drop due to O/F variation is well below 0.2%, a value which is too small to be measured in an actual motor test. It is also shown that for a wagon wheel type multiport configuration (with triangular ports), efficiency drop is significantly worse than the single circular port case. Even for the multiport systems, the shift does not have a controlling effect on the overall efficiency of the motor. A number of strategies have been outlined to control the adverse effects of O/F variation in a hybrid rocket. For a single circular port design with limited throttling, no mitigation is required. For systems with deep throttling requirements, aft oxidizer injection seems like a viable strategy to retain a high level of overall efficiency.Publication Metadata only “Poor but achiever”: social capital, ethnicity, school achievement(Eğitim Araştırmaları Birliği, 2018) Department of Sociology; Çelik, Çetin; Faculty Member; Department of Sociology; College of Social Sciences and Humanities; 105104This study uses Bourdieu's social capital concept to analyze the impacts of the parental networks on the educational success of their children by comparing student-mother and dropout-mother interviewee pairs living in disadvantaged areas of Istanbul. The findings obtained from the research reveal that; (1) although they live in the same disadvantaged neighbourhoods, students continuing to attend school differ from school dropouts in terms of socioeconomic and ethnic terms; (2) school dropouts are predominantly from Kurdish and Roma families living in marginal poverty; (3) the network structures of the parents of school drop-outs and nondropouts significantly differ in the nexus of socioeconomic resources and ethnicity; and (4) differences in network structures favouring parents of those continuing to attend school are mobilized to improve the school success. This research argues that this differentiation between the two groups regarding opportunities and constraints may be the result of the historical memory of the ethnic groups who occupy differing positioning the ethnoreligious hierarchy of Turkish society. / Bu çalışma Bourdieu’nün sosyal sermaye kavramını kullanarak İstanbul’un dezavantajlı bölgelerinde yaşayan, halihazırda okula devam eden ve kısa bir süre önce okulu terk etmiş öğrenci ebeveynlerinin ağ yapılarını çocuklarının eğitim başarısına etkileri bakımından ayrıntılı olarak analiz etmektedir. Araştırmadan elde edilen bulgular şunlardır: (1) Her ne kadar aynı dezavantajlı mahallelerde yaşıyor olsalar da okula devam eden öğrenciler sosyoekonomik ve etnik açıdan okul terklerden ayrışmaktadır; (2) okul terkler ağırlıklı olarak marjinal yoksulluk koşullarında yaşayan Kürt ve Roman ailelerden gelmektedir; (3) okula devam edenlerin ve okulu terklerin ebeveynlerinin ağ yapıları sosyoekonomik ve etnisite olarak önemli derecede farklılaşmaktadır; ve (4) okula devam edenlerin ebeveynleri lehine olan ağ yapılarındaki farklılıklar, çocukların okul başarısını artırmak için mobilize edilmektedir. Araştırma, fırsat ve kısıtlara ilişkin bu grupsal farklılaşmaların onların Türkiye toplumda uzun süredir işgal ettikleri etnik konumlarının yarattığı bir toplumsal hafızadan kaynaklanabileceğini ileri sürmektedir.Publication Metadata only “Smart poisoning” of Co/SiO2 catalysts by sulfidation for chirality-selective synthesis of (9,8) single-walled carbon nanotubes(2016) Yuan, Yang; Karahan, H. Enis; Wei, Li; Zhai, Shengli; Lau, Raymond; Chen, Yuan; N/A; Yıldırım, Cansu; Birer, Özgür; Master Student; Researcher; Koç University Surface Science and Technology Center (KUYTAM) / Koç Üniversitesi Yüzey Teknolojileri Araştırmaları Merkezi (KUYTAM); N/A; N/A; N/AThe chirality-selective synthesis of relatively large (diameter > 1 nm) single-walled carbon nanotubes (SWCNTs) is of great interest for a variety of practical applications, but only a few catalysts are available so far. Previous studies suggested that S (compounds) can enhance the chirality-selectivity of Co catalysts in SWCNT synthesis, however, the mechanism behind is not fully understood, and no tailorable methodology has yet been developed. Here, we demonstrate a facile approach to achieve the chirality-selective synthesis of SWCNTs by the sulfidation-based poisoning of silica-supported Co catalysts using a mixture of H2S and H2. The UV-vis-NIR, photoluminescence, and Raman spectroscopy results together show that the resulting SWCNTs have a narrow diameter distribution of around 1.2 nm, and (9,8) nanotubes have an abundance of ∼38% among the semiconducting species. More importantly, the carbon yield achieved by the sulfided catalyst (2.5 wt%) is similar to that of the nonsulfided one (2.7 wt%). The characterization of the catalysts by X-ray diffraction, X-ray photoelectron spectroscopy, X-ray fluorescence, and H2 temperature-programmed reduction shows that the sulfidation leads to the formation of Co9S8 nanoparticles. However, Co9S8 nanoparticles are reduced back to regenerate metallic Co nanoparticles during the synthesis of SWCNTs, which maintain a high carbon yield. In this process, Co9S8 nanoparticles seemingly intermediate the production of Co nanoparticles with narrow size distribution. Due to the fact that the poisoning step improves the quality of the end-product rather than hampering the growth process, we have coined the process developed as “smart poisoning”. This study not only reveals the mechanism behind the beneficial role of S in the selective synthesis of relatively large SWCNTs but also presents a promising method to create chirality-selective catalysts with high activity for scalable synthesis.Publication Metadata only ‘Culture’ in EU–Turkey relations(Taylor and Francis, 2016) Department of International Relations; N/A; Rumelili, Bahar; İşler, Didem Çakmaklı; Faculty Member; PhD Student; Department of International Relations; College of Administrative Sciences and Economics; Graduate School of Social Sciences and Humanities; 51356; 260783Contemporary socio-political and economic situations in the countries of SEE greatly influence their mutual relationships which are already bearing heavy loads from the past as well as distinct visions of the future. Politicians are forced to change their own priorities, sometimes even decisions, to fit the daily demands of their coalition partners or the expectations of public opinion which are often influenced by populist officials and media. The government and majority representatives condemning crimes committed in Srebrenica approved the decision of the European Parliament. Yugoslav cultural diplomacy was tuned equally toward West and East and also toward countries of the third world. All Balkan countries are open to global cultural flows but, paradoxically, their institutional systems are still closed towards the products of mass culture of neighbouring countries, particularly in the case of ethno-pop or folk music. International dimensions of national cultural policies of the Balkans primarily focus on transferring knowledge, improving the national image and increasing national influence.Publication Metadata only ‘Culture’ in EU–Turkey relations(Ashgate Publishing Ltd, 2011) Department of International Relations; Rumelili, Bahar; İşler, Didem Çakmaklı; Faculty Member; PhD Student; Department of International Relations; College of Administrative Sciences and Economics; Graduate School of Social Sciences and Humanities; 51356; 260783Contemporary socio-political and economic situations in the countries of SEE greatly influence their mutual relationships which are already bearing heavy loads from the past as well as distinct visions of the future.

While social ecology, spearheaded by Murray Bookchin, stresses the tangle of ecological and socio-political issues and advocates for a transformative viewpoint in both spheres, new materialism destabilizes the nature/culture dichotomy by reading the production of matter and meaning as co-extensive praxes and by defining phenomena, in Karen Barad’s terms, as the “ontological inseparability of intra-acting agencies.” Ergin reads social ecology and new materialism, respectively, in relation to deconstruction to tease out the different models of entanglement in each school of thought and to elucidate what is at stake in the motif of entanglement. She rethinks these three strands of thought vis-à-vis each other to capture some of the breadth and variety in reconceptualizations of natural-social and material-discursive entanglements.Publication Metadata only 1,3-bis(gamma-aminopropyl)tetramethyldisiloxane modified epoxy resins: curing and characterization(Elsevier, 1998) Department of Chemistry; Department of Chemistry; Yılgör, Emel; Yılgör, İskender; Researcher; Faculty Member; Department of Chemistry; College of Sciences; College of Sciences; 40527; 24181Incorporation of siloxane oligomers with reactive organofunctional terminal groups, such as amine, epoxy and carboxy, into the structure of epoxy networks, provides improvements in the fracture toughness, water absorption and surface properties of the resultant systems. 1,3-bis(gamma-aminopropyl) tetramethyldisiloxane (DSX) was used as a model curing agent and modifier in bis(4-aminocyclohexyl)methane (PACM-20) cured diglycidyl ether of bisphenol-A (DGEBA) based epoxy resins. Curing reactions followed by differential scanning calorimetry indicated faster reaction rates between DSX and DGEBA as compared with PACM-20 and DGEBA. Mechanical characterization of the modified products showed improvements in tensile and impact strengths as expected. Glass transition temperatures of these materials showed a decrease with an increase in DSX content.Publication Metadata only 1.07 - Rubberlike elasticity(Elsevier, 2012) Mark, J.E.; Department of Chemical and Biological Engineering; Erman, Burak; Faculty Member; Department of Chemical and Biological Engineering; College of Engineering; 179997Molecular structure, molecular and phenomenological theories, and computer simulations of amorphous rubberlike polymeric networks of rubber elasticity are discussed.
