39 spatial arrangement of the animal male germ cell genome: II. 2d-3d Simulation and visualization of spatial configuration of major chromosome 2 in Drosophila sperm
(İstanbul Kültür Üniversitesi, 2007-09) Alexandrov, Igor D.; Stepanenko, Victor A.; Alexandrova, Margarita V.
Data on the non-random distribution of radiationinduced inversion breakpoints were used as genetic markers for 2D and 3D modeling of the largescale architecture of the chromosome 2 in Drosophila sperm genome at the time of irradiation. During modeling, Gmax program with application of splines, the additional objects and operations as well as the methods of visualization of macromolecular biostructures were employed. A specific megarosette-loop model of spatial arrangement of chromatin fiber in the haploid sperm nucleus can account well for the experimental data.

4 4 Bipyridyl Vibrational Assignments and Force Field
(Elsevier, 1995-04) Topaçlı, Arzu; AKYÜZ, SEVİM; 170067; 10127
A normal coordinate analysis of 4,4′-bipyridyl (4,4′-bipy) is carried out to establish consistent vibrational assignment and to determine a Urey-Bradley force field. The potential energy distribution of 4,4′-bipy is calculated which has provided certainty for the assignments. Additional information is obtained from the vibrational spectra of M (4,4′-bipy)Cl2 complexes (where M = Zn, Cu or Cd) and calculated wave numbers of complexed 4,4′-bipy. Several vibrational modes of 4,4′-bipy in the IR and Raman spectra of the complexes are found to have upward shifts in frequency compared to those in the free molecule and the shifts are metal dependent. An explanation supported by the normal coordinate analysis is provided in terms of coupling with low frequency vibrations, particularly the M-N stretching frequencies.

A biomimetic research on how cities can mimic forests to become sutainable and smart
(2020-06) KARABETÇA, ALİYE RAHŞAN
In nature, everything is functional concerning each other. Every single organism supports the other either with a symbiotic relationship or in terms of form and/or function; such as some trees shed their leaves to the ground to prepare themselves for strong winter conditions and also to create nutrition for microorganisms and fungi under the surface. This kind of interaction of nature could lead architects to develop better solutions to create better built environments which is the main objective of this paper. It aims to clarify and prove that nature is the greatest mentor and can teach humanity many solutions about designing smart cities. In this context, using biomimicry as a design strategy is the main methodology. Biomimicry and biology will be the scientific fields for researching and understanding the structural strength, bioclimatic properties, functional morphology and other important features of forests which will be explained to identify forests and state solutions for developing smart cities. Outcomes of this paper aim to scientifically state that forests are naturally sustainable built environments which are the greatest examples for smart cities and when they unite, they are able to create the most suitable living environments for other living organisms.

A Brief Evaluation of the Decision of the European Court of Human Rights: Celebi and the Others v. Turkey
(Seçkin Yayıncılık, 2017-05) Güler, Zeynep; 245972
In 17 August 1999, an earthquake in north-western Turkey occurred and caused deaths of thousands of people and destruction of the buildings. After this loss, many people brought action against the construction companies for using poor quality materials in the buildings. In these cases, different chambers of Court of Cassation decided in different ways in respect of starting of the limitation period. In the Case Çelebi and Others v. Turkey, European Court of Human Rights emphasized that the different interpretations of the same regulation cause infringement of the legal security principle. The Court held the violation of Article 6 of the Convention.

A Case Study in University and Community Integration: Science Meets with Children at University

This study was undertaken to investigate whether children’s perceptions of science and scientists changed following their participation in the science education program within the scope of “Science Meets with Children at University”-the project which was initiated at Ankara University by Ankara Development Agency, and it was also intended to find out whether the science education program affected children’s future job choices. Within the scope of the project “Science Meets with Children at University”, 6319 children attended half-day education sessions.“Questionnaire of Views on Science and Scientists” was administered to 4688 of the children who volunteered to take part in the study. The results indicated that there were changesin the views of the children following the education program, their views on science and the scientist changed positively after education program 90,4% of children reported they would like to choose a science-related career in the future and 90.1% of them said they would like to attend the education program again.

A Cinematic Narration Of The Great Depression: Recalling John Ford’s The Grapes Of Wrath
(The Turkish Online Journal of Design Art and Communication, 2014-01) Yılmazok, Levent; TR42255
John Steinbeck’s novel The Grapes of Wrath, published in 1939, depicts the poverty of 1930s America during the “Great Depression” through the tragedy of the Joad family, who lost their home and land in Oklahoma and have to drive to California in the hope of finding employment and plenty like many other farmers. The novel was adapted for the cinema the same year and directed by John Ford. Proving welcome in cinema circles and taking its place as a master work in film history, it was one of the few films with radical political connotations hitherto produced by Hollywood. Nevertheless, this cinematic version of the Great Depression narrative has not escaped criticisms, which have been aimed chiefly at aspects of its content that diverge from its parent work. Compared with the novel, the film has been considered more conservative and optimistic, on the grounds that, although the novel emphasizes the class conflict and portrays the Joads as only one of the many suffering families, the film exerts a redundant focus on the family and commends family values: divergences considered to be supported by the visual style of the film. In this article, while recalling Ford’s The Grapes of Wrath, I revisit the above-mentioned criticisms and reassess them in relation to the parenting novel. In doing so, this article also aims to evoke the ongoing economic recession that influences the masses all over the world and the recurrent, unchanging and inevitable outcomes that such crises of capitalism bring for its victims.

A Comparative Study of Smoothing a Vehicle s Trajectory which is Calculated by an Evolutionary Algorithm
(2016-06) Buran, Bayram Ali; Çağlar, Süleyman Hikmet; ŞAHİNGÖZ, ÖZGÜR KORAY; 214903; 243931; 114368
Determining a vehicle’s trajectory is a complex and hard to solve type problem in the literature and it is identified as a NP-Hard optimization problem which is studied in different engineering disciplines such as computer, electrical and industrial engineering. It has been observed that such complex problems can be solved by using various approaches and lots of them are focused on the usage of Evolutionary Algorithms especially in case of a large number of controls points which are needed to be visited. Although these algorithms provide near optimal solutions, in the real world, vehicles are not able to follow this determined path (trajectory) without any deviation. Because vehicles are moving objects and each one moves with a certain speed. Therefore it is impossible for a vehicle to make a sharp turn after visiting control points. These vehicles need to make smoothed turns over these points. Therefore there will be a certain difference between the calculated path and the real path. It is needed to determine the real path by using necessary mathematical solutions for smoothing these paths. To ensure the motion continuity of vehicles, they need to follow paths determined according to a certain criterion. In this study, the most common smoothing methods which are used to ensure these continuities (Bezier, B-Spline and Dubins) have been compared and it is aimed to show the different approaches in an application area of path planning problems as a comparative study.
