Publication Embargo İmparatorluk Döneminde Denizciliğimiz: Ova'dan Okyanusa Turgut Reis(2010) Çelik, Yakup; 7328Bu çalışmada Türk denizcilik tarihinde önemli yeri olan Turgut Reis’in hayatının konu alındığı bir roman üzerinde durulmuştur. Turgut Reis romanında, yazarın Osmanlı İmparatorluğuna eleştirileri, çöküşün asıl nedenleri üzerine yaptığı yorumlar ele alınmıştır. Romandan hareketle, “Halikarnas Balıkçısı, Osmanlı İmparatorluğu döneminde denizciliğimizin ihmal edildiği görüşündedir”, tezi ortaya konulmaktadır. Ayrıca, kurgunun temelini oluşturan çatışma üzerinde durulmuş, bir köylü çocuğunun bütün dünyaya nam salan kahraman hâline gelişinin öyküsü de incelenmiştir.Publication Embargo Multivalued Sakaguchi functions(2007)Let A be the class of functions f(z) of the form f(z) = z +a2z2 + ··· which are analytic in the open unit disc U = {z ∈ C||z| < 1}. In 1959 [5], K. Sakaguchi has considered the subclass of A consisting of those f(z) which satisfy Re zf (z) f(z)−f(−z) > 0, where z ∈ U. We call such a functions “Sakaguchi Functions”. Various authors have investigated this class ([4], [5], [6]). Now we consider the class of functions of the form f(z) = zα(z +a2z2 +···+anzn +···) (0 <α< 1), that are analytic and multivalued in U, we denote the class of these functions by Aα, and we consider the subclass of Aα consisting of those f(z) which satisfy Re zDα z f(z) Dα z f(z)−Dα z f(−z) > 0 (z ∈ U), where Dα z f(z) is the fractional derivative of order α of f(z). We call such a functions “Multivalued Sakaguchi Functions” and denote the class of those functions by Sα s . The aim of this paper is to investigate some properties of the class Sα s . 2000 Mathematical Subject Classification: Primary 30C45.Publication Open Access Çocuğunuzun Yanında Olmak(İstanbul Kültür Üniversitesi / Eğitim Fakültesi, 1993) Shahmoon Shanok, Rebecca; Hacıfazlıoğlu, Özge; Şimşek, HasanPublication Embargo Survey on Access Control Mechanisms in Cloud Computing(River Publishers, 2018-05-26) AKBULUT, AKHAN; BAYDOĞMUŞ, GÖZDE KARATAŞ; 110942; 116056The benefits that Internet-based applications and services have given to the end user with today’s cloud computing technology are very remarkable. The distributed services instantly scaled over the Internet provided by cloud computing can be achieved by using some mechanisms in the background. It is a critical task for end users to control access to resources because lack of control often leads to security risks. In addition, this may cause systems to fail. This paper describes seven different access control mechanisms used in cloud computing platforms for different purposes. Besides, the advantages and disadvantages of various models developed from previous service-based architectures and used for cloud computing are detailed and classified. During the assessments, NIST’s metrics were taken as a reference, and in the study, 109 articles from the past decade were examined. We also compared our research with the existing survey papers.Publication Embargo Violence and melancholia: The story of melancholic “Butterfly” generation(2016) Gündoğdu, Bucu; 218753In his work entitled “Mercury fur”, Philip Ridley imagines a post–apocalyptic capitalist society plagued by the butterflies, multi-colored drugs, which induce memory loss and social collapse, particularly in younger generation. In addition to the drug dealing, violence and child abuse become another source of income in this capitalist world that suffers from loss of communication and empathy. This is one of the reasons that lead characters to develop melancholic subjectivity and strengthen their tendency to resort violence. Characters suffer from permanent melancholia state due to ongoing modern civil wars that turn the world into a “Waste Land” as in T.S Eliot’s poem. Just as Samuel Beckett’s characters, Vladimir and Estragon in “Waiting for Godot”, the brothers of “Mercury Fur”, Eliot and Darren think hope and belief are replaced with disbelief and despair. In this text, it is not an existential crisis that is focused on though, it is the post-war crisis causing moral bankruptcy and lack of commitment to life because threat is everywhere and capitalism demerits humane values. The Gang culture resurfaces again and dominates the young brains and incites them to do violent actions. This text has been examined from the perspective of Freudian theory of “Melancholia and Mourning”, which sheds light on the reasons why these characters suffer from melancholia, depressive psychoses and perversions. Though at first glance, it seems difficult to overcome shell-shock experience, moral degeneration and prevent familial institution’s disintegration, Ridley considers the best cure to work through the problems is story-telling. To exchange personal stories plays a big role in stimulating bitter-sweet memories, keeping family ties close and regaining sense of self even in the time of war.Publication Restricted Comparison of Tolerance Related Proteomic Profiles of Two Drought Tolerant Tomato Mutants Improved by Gamma Radiation(Elsevier B.V., 2021) ÇELİK, ÖZGE; AYAN, ALP; MERİÇ, SİNAN; ATAK, ÇİMENLycopersicon esculentum L., also known as tomato, is an important industrial plant due to its products which worth billions of dollars annually, besides its nutritional value and health benefits. In this study, we investigated the two-dimensional protein expression profiles in drought tolerant mutant plants derived from industrial 5MX12956 tomato variety by Cs-137 gamma radiation source induced mutations. Drought tolerance of mutants were evaluated and confirmed by in vivo and in vitro methods. Eleven drought responsive protein spots were identified by two-dimensional electrophoresis and MALDI-TOF-MS. Identified proteins which presented differential expression under drought conditions were clustered under six distinct groups based on their cellular functions. These clusters are ATP and carbohydrate metabolism, mRNA processing and protein phosphorylation, oxidation reduction and stress response, signaling and supporting cytoskeleton. Our results contributed proteomic data to drought tolerance of our tomato mutants which were originated from drought susceptible 5MX12956 variety. They may also facilitate basis for future investigations into the genetic and physiological aspects of this tolerance. © 2021 Elsevier B.V.Publication Open Access Okullar açılırken(İstanbul Kültür Üniversitesi / Eğitim Fakültesi, 1989)Publication Open Access Bilgisayar destekli eğitim(İstanbul Kültür Üniversitesi / Eğitim Fakültesi, 1986-10-17) Baykal, AliPublication Embargo Close-to-convex functions defined by fractional operator(2013) Aydoğan, Seher Melike; Kahramaner, Yasemin; POLATOĞLU, YAŞAR; 35549; 8366; 199370Let S denote the class of functions f(z) = z + a2z2 + ... analytic and univalent in the open unit disc D = {z ∈ CPublication Open Access The Heybeliada Talks: Sharing Ideas from and for Cyprus(Istanbul Kültür University / Küresel Siyasal Eğilimler Merkezi / Global Political Trends Center, 2014) Constanti, Costa; Hadjidemetriou, Takis; Hatay, Mete; Kyriacou, Praxoula Antoniadou; Özuslu, Sami; Pericleous, Chrysostomos
