Ege denizi ve Marmara denizi’ndeki adalardan Türkiye kemirici faunasının karyolojisine ve yayılışına katkılar
No full textA chromosomal study on five different rodent species (Mus domesticus, Mus macedonicus, Apodemus sylvaticus, Apodemus witherbyi and Rattus rattus) from Gökçeada and Bozcaada in Aegean Sea and Marmara Island in Marmara Sea was performed to fill the deficiency of karyological information about island populations of these species. Diploid chromosome sets (2n) and fundamental numbers of chromosomal arms (NF) were determined to be 2n = 40, 40, 48, 48 and 38, NF = 40, 40, 48, 48 and 60 for M. domesticus, M. macedonicus, A. sylvaticus, A. witherbyi and R. rattus respectively. Results showed that there was no difference between karyological values in island and continental populations of those rodents, although Aegean and Marmara seas have served as geographic barriers for a long time between islands and mainland. In addition to the karyotypes of M. domesticus, M. macedonicus, A. sylvaticus and R. rattus, their presence in Marmara Islands were firstly determined by current studyBeş farklı kemirici türünün (Mus domesticus, Mus macedonicus, Apodemus sylvaticus, Apodemus witherbyi ve Rattus rattus) Türkiye’deki ada populasyonlarına ilişkin karyolojik bilgi eksikliğini gidermek amacıyla, bu türlerin Ege Denizi’nde yer alan Gökçeada ve Bozcaada ile Marmara Denizi’nde yer alan Marmara Adası’nda yayılış gösteren populasyonları üzerine kromozomal bir çalışma gerçekleştirilmiştir. M. domesticus, M. macedonicus, A. sylvaticus, A. witherbyi ve R. rattus için diploit kromozom sayıları ve temel kromozom kol sayıları sırasıyla 2n = 40, 40, 48, 48 ve 38, NF = 40, 40, 48, 48 ve 60 olarak belirlenmiştir. Ege Denizi ve Marmara Denizi bu türlerin adalarda ve anakarada yayılış gösteren populasyonları arasında gen akışının kesilmesine neden olan coğrafik bariyerler olarak uzun süredir görev yapmaktadır, buna rağmen, bu çalışma ile bu kemirici türlerinin adalarda ve anakarada yayılış gösteren populasyonları arasında karyolojik bakımdan herhangi bir farklılaşma olmadığı tespit edilmiştir. Ayrıca, M. domesticus, M. macedonicus, A. sylvaticus ve R. rattus’un Marmara Adası’nda yayılış gösterdiği ilk kez bu çalışma ile belirlenmişti
Determination of genetic variations in the genus Dryomys Thomas, 1906 (Rodentia: Gliridae) distributed in Turkey using NADH dehydrogenase 1 (ND1) gene
No full textWOS: 000439832300013PubMed: 29072519Genetic diversity and phylogeny of Dryomys nitedula and Dryomys laniger from Turkey was described in the present study by using mitochondrial DNA NADH dehydrogenase 1 gene (ND1). Genetic variation in ND1 gene was determined by two model-based phylogenetic analyses and a network analysis revealed 27 haplotypes of D. nitedula constructing four main lineages (Thrace, Anatolia, North-eastern Anatolia and Savsat) that have non-overlapping geographic distributions and no shared haplotypes, but on the other hand, three haplotypes were detected in four samples of D. laniger from Turkey. It was determined that nucleotide diversity was low but haplotype diversity was high in D. laniger, whereas, D. nitedula has both high level of haplotype and nucleotide diversity. Characterization of Thrace lineage of D. nitedula with low nucleotide diversity and determination of the total nucleotide diversity of Anatolian lineages (Anatolia + North-eastern Anatolia + Savsat) to be approximately four times higher than that of Thrace lineage indicated that Anatolia may have served as a refuge for D. nitedula. Divergence times and high level of nucleotide differences between D. nitedula lineages showed that diversification of the lineages may have occurred before and during ice ages in Turkey, thought to be a refuge for post-glacial colonization and biodiversity resource of Europe. Additionally, estimated divergence times and calculated genetic distances yielded compatible results with the previous paleontological and genomic data for the diversification time of two species in the genus.Scientific Research Projects Coordination Unit of Nigde Omer Halisdemir University [YULTEP FEB 2015/06]; Scientific and Technological Research Council of Turkey (TUBITAK) [113Z822]This study was supported by Scientific Research Projects Coordination Unit of Nigde Omer Halisdemir University [grant number: YULTEP FEB 2015/06] and The Scientific and Technological Research Council of Turkey (TUBITAK) [grant number: 113Z822]
The cinema of Engin Ayça
No full textBu tez, 1968’den beri sinema üzerine teorik ve pratik çalışmalar yapan yönetmen Engin Ayça’nın literatürde hemen hemen hiç yer verilmeyen kurmaca filmlerini ortaya çıkaran dinamikleri ve yönetmenin filmlerinde anlamın sinemasal olarak nasıl inşa edildiğini derinlemesine incelemeyi amaçlamıştır. Çalışmada, yönetmenin Bez Bebek (1987), Soğuktu ve Yağmur Çiseliyordu (1990) ve Suna (2007) filmleri analiz edilmiştir. Nitel araştırma yöntemi kullanılan bu tezde, Ayça’nın yönetmenliğini üstlendiği kurmaca filmler, sinema üzerine kaleme aldığı metinler ve yönetmenle bire bir yapılan görüşmelerden veriler elde edilmiştir. Engin Ayça’nın kurmaca filmleri analiz edilirken; filmlerin anlatısına, anlatımına, mizansen düzenlemelerine, filmlerin ortaya çıkmasına neden olan dışsal parametreler arasında yer alan yapım koşullarının auteur üretim pratiklerine uyup uymadığına, yönetmenin habitusunun kültürel ürünlerindeki etkisine ve filmlerin 1980’lerin kadın filmleri arasındaki konumuna odaklanılmıştır. Filmlerin sanat sineması anlatımı ve kişisel üretim tarzına uygun olarak tasarlandığı, yönetmenin habitusunun filmlerin üretim sürecinde ve anlatısında etkili olduğu, Bez Bebek ve Soğuktu ve Yağmur Çiseliyordu filmlerinde mizansen düzenlemeleri ve tema arasında uyum bulunduğu, yönetmenin toplumsal dönüşüm kaygısıyla filmler ürettiği, klasik anlatı sinemasının üslupsal tarzına alternatif bir sinema dili kullandığı ve böylece kadın karakterlerin bedenlerini teşhir etmeden görselleştirdiği ortaya konmuştur. Yönetmenin, Türk sinemasındaki diğer yönetmenlerden farklı olarak sinema üzerine ürettiği teorik ve pratik çalışmalarını devamlılık içinde geliştirdiği öne sürülmüştür. Bu çalışma Engin Ayça sinemasını ortaya çıkaran koşulları anlamak için faydalı olacaktır.This thesis aims to examine in depth the dynamics that reveal the fiction films of director Engin Ayça, who has been doing theoretical and practical studies on cinema since 1968, and how meaning is cinematically constructed in the director's films. In the study, the director's films Bez Bebek (1987), Soğuktu ve Yağmur Çiseliyordu (1990) and Suna (2007) were analyzed. In this thesis, which uses the qualitative research method, data were obtained from the fiction films directed by Ayça, the texts he wrote on cinema and one-on-one interviews with the director. While analyzing Engin Ayça's fiction films, the focus was on the narrative of the films, the narration, how to compose elements of mise-en-scêne, whether the production conditions match with the author production practices, the influence of the director's habitus on the films and the position of films among the women's films of the 1980s which are among the external parameters that cause the films to appear. It has been revealed that the films are designed in accordance with the narrative of art cinema and personal production style, the director's habitus is effective in the production process and narrative of films, there is harmony between the elements of mise-en-scêne and the theme in Bez Bebek and Soğuktu ve Yağmur Çiseliyordu, the director produces films with the concern of social transformation, uses an alternative cinematic language to the stylistic style of classical narrative cinema and thus visualizes the bodies of female characters without exposing them. It has been suggested that the director, differently from other directors in Turkish cinema, has consistently developed his theoretical and practical works on cinema. This study will be useful to understand the conditions that gave rise to the cinema of Engin Ayça
Study of tip clearance effects in centrifugal fans with unshrouded impellers using computational fluid dynamics
No full textPerformance of centrifugal fans with unshrouded impellers strongly depends upon complex configuration of the asymmetrical flowfield in the axial direction, which is highly unsteady. The flowfield, in turn, is considerably affected by the design parameters of both scroll and impeller geometry, for which tip clearance is of particular interest. This article presents a three-dimensional computational fluid dynamics (CFD) simulation of the flowfield in three different unshrouded centrifugal fan impellers with varying tip clearances. A commercial CFD code, namely, Fluent V6.2.16 with a k-epsilon two-equation turbulence model was utilized in order to study the effects of tip clearance on the overall performance of each fan with the tip clearances ranging from 5 to 30 mm. The numerical results were compared with the experimental data reported previously in the literature by the present author and his colleagues, and excellent agreements were observed for each fan

Mitochondrial DNA (Cytochrome b and control region) analysis of Apodemus species Kaup, 1829 (Mammalia:Rodentia) in North Anatolia and Thrace
No full textBu tez çalışmasında Türkiye'nin kuzeyinde, Trakya'da ve yüz ölçümü bakımından sırasıyla Türkiye'nin üç büyük adası olan Gökçeada, Marmara Adası ile Bozcaada'da yayılış gösteren Apodemus cinsine dahil örneklerin mitokondriyal DNA'sının sitokrom b ve kontrol bölgesindeki varyasyonlar araştırıldı. DNA dizi analizi sonucunda elde edilen bulgular bu tezin kapsamındaki çalışma alanında Apodemus cinsinin 6 türünün (Apodemus flavicollis, Apodemus mystacinus, Apodemus witherbyi, Apodemus uralensis, Apodemus sylvaticus ve Apodemus agrarius) yayılış gösterdiğini ortaya çıkardı. A. flavicollis'in Trakya ve Anadolu populasyonlarının iki farklı genetik soy hattı oluşturduğu belirlendi. A. mystacinus populasyonları Batı Karadeniz ve Orta/Doğu Karadeniz olmak üzere iki farklı genetik gruba ayrıldı. Bu güne kadar Türkiye'de sadece Anadolu'nun büyük bölümünde yayılış gösterdiği bilinen A. witherbyi populasyonlarının Trakya'da yayılışının olduğu ilk kez bu çalışma ile tespit edildi. A. uralensis populasyonları arasında gen akışının devam ettiği, dolayısıyla genetik farklılaşmanın az olduğu sonucuna varıldı. Parçalı yayılışa sahip olan A. sylvaticus'un Anadolu'dan tek bir lokalitedeki Kurupelit (Samsun) populasyonu ile Gökçeada, Marmara adası ve Trakya populasyonları arasında yüksek genetik farklılıkların bulunduğu açığa çıkarıldı. Trakya'da yayılışı olan A. agrarius'un sadece bir lokaliteden incelenen populasyonunda haplotip çeşitliliğinin yüksek, nükleotid çeşitliliğinin düşük seviyede olduğu bulundu. Miyosen, Pliyosen ve Pleyistosen dönemlerinde meydana gelen jeolojik, tektonik olaylarla beraber iklim değişikliklerinin Apodemus cinsi türlerinin genetik farkılılaşması üzerinde etkili olduğu ortaya kondu.In this thesis, variations in cytochrome b and control region of mitochondrial DNA in the samples of the genus Apodemus distributed in northern Turkey, Thrace and three islands in Turkey (Imbros, Marmara Island and Tenedos, which are the biggest islands of Turkey according to the their surface areas, respectively) were investigated. The findings provided by DNA sequence analysis revealed that 6 species of Apodemus (Apodemus flavicollis, Apodemus mystacinus, Apodemus witherbyi, Apodemus uralensis, Apodemus sylvaticus and Apodemus agrarius) live in the study area of this thesis. It was determined that Thrace and Anatolia populations of Apodemus flavicollis formed two different genetic lineages. Apodemus mystacinus populations were divided into two different genetic groups (Western Black Sea and Central/Eastern Black Sea). So far, A. witherbyi populations, which has been known to be lived in the most parts of Anatolia, were recorded from Thrace for the first time by this thesis. A continuing gene flow and therefore little genetic differentiation between A. uralensis populations were determined. It was deduced that there was high genetic differentiation between Kurupelit (Samsun) population and populations from Imbros, Marmara Island and Tenedos of A. sylvaticus distributed in fragmented habitats. It was found that one population of A. agrarius from only one locality in Thrace had high haplotype diversity, but, low nucleotide diversity. It was determined that geologic, tectonic events as well as climatic oscillations occurred during Miocene, Pliocene and Pleistocene had an impact on the genetic differentiation of Apodemus species

Expressing manner, location, and orientation in manner-only motion events in Turkish sign language
No full textArık, Engin (Dogus Author)The path and manner of objects in motion events have been studied in many languages. Previous research has focused on whether both path and manner are expressed in the main verb and whether manner can be omitted due to saliency, narrative style, or available linguistic constructions of a particular language. However, it is unknown to what extent language users express manner when it is salient and marked. Aiming to fill this gap, the present study asked how Turkish Sign Language (TİD) signers express location, orientation, and manner in a basic motion event including manner but not path. Eight TİD signers participated in an experiment and described what they saw in 34 brief videos to an addressee. Results showed a significant difference between expressions of location, orientation, and manner or leaving them ambiguous. While TİD signers encoded manners of motion obligatorily, they gave the locations of the objects more than their orientations. Thus, when manner is salient, it must be encoded regardless of language family or modality
THE EFFECTS OF KITSCH CONCEPT ON THE AESTHETIC PERCEPTION AND TASTE OF HIGH SCHOOL STUDENTS
No full textBu araştırmada, Ankara ili merkezinde yaşayan ve farklı liselerde okuyan
öğrencilerin estetik algı ve beğenilerinin, kitsch olgusundan etkilenme düzeyleri ve
öğrencilerin kitsch ürünleri benimsemelerinin altında yatan faktörler
belirlenmektedir.
Her geçen gün kültürün yozlaşması ve popüler kültürün hızla yayılması ile
ortaya çıkan kitsch olgusu ve ürünleri toplumun her kesiminden insanları ve
dolayısıyla eğitim sistemimizdeki öğrencilerimizi olumsuz yönde etkilemektedir.
Araştırmada; öğrencilerin estetik algı ve beğeni gelişimlerinin, kültür endüstrisinin
ideolojisi doğrultusunda ticari amaçlarla üretilen, kitsch ürünler tarafından
etkilenmesindeki nedenlerin ortaya konulması ve öğrencilerin bu olumsuz etkilerden
kendilerini nasıl koruyabilecekleri sorusuna yanıtlar bulunması amaçlanmıştır.
Çünkü öğrencilerimizin, hiçbir sanatsal değeri olmayan ve tamamen ticari kaygılarla
sisteminin işleyişine ve devamlılığına hizmet etmesi için üretilen aldatıcı ve ikiyüzlü
yoz sanatı benimseyip etkilenmeleri, geleceğimizi oluşturacak olan toplumun
yapısını ve sağlığını olumsuz yönde etkileyecektir.

This study aims to find out the degree of the influence of kitsch concept on the
taste and aesthetic perception of students who live and study in different high schools
in the centre of Ankara and the reasons why students adopt the products of kitsch.
Day by day, because of the development of cultural degeneration and the high
spread of popular culture, the concept of kitsch and its products affect not only
people from different classes of society but also our students in the education
system.This study aims to explain the students' aesthetic perception and taste
development, kitch products which are produced by the ideology of culture industry
and also aims to find out the answers of the questions why students are influenced
by the kitch products and how they can protect themselves from these negative
effects. Because; if our students adopt or if they are influenced by the degenerated,
deceiving work of art which has no artistic value and which has been produced with
financial worries to serve the continuation of the system, the development and
structure of our future society and new generation will be influenced negatively.
After the analysis of the results, it is seen that the education level of the
families of the students who are studying in high schools effects students habits of
reading books, watching TV, interest in arts and adoption of kitsch products.
In the conclusion part of the study, suggestions of the researcher take place
which are based on the problems mentioned
Computation of the potential trade of Turkey in the OIC market through estimator selection process
No full textSorhun, Engin (Dogus Author)As the trade volume of Turkey has tripled in the last decade, one observes a complementary shift in the trade orientation of the country from its conventional markets like the European Union to Asian and African markets. Among the alterative markets, the members of the Organization of Islamic Cooperation (OIC) have become particularly important in the market diversification policy of Turkey. In this respect, computing the actualized trade potential can not only account for the dynamic change in trade orientation of the country but also presents a guideline for policy makers and firms. On the other hand, since recent research in literature stated that estimations of potential trade through a single estimator (monotype estimation) lead to overestimations (or underestimations) which misguide policy makers; thus, this paper employs an estimator selection process. For that purpose, this study uses a gravity model estimated by multiple alternative estimators to assure the econometric credibility. This paper aims at (1) choosing the most adequate estimator possible for the case through an estimator selection process, (2) computing the trade potential of Turkey in the OIC market, and (3) revealing to what extent the trade potential has been actualized up to now
