    TUR, KAZIM/0000-0002-8017-8209Articular cartilage defects heal very poorly and lead to degenerative arthritis. Existing medications cannot promote healing process; cartilage defects eventually require surgical replacements with autografts. As there is not enough source of articular cartilage that can be donated for autografting, materials that promote cartilage regeneration are important in both research and clinical applications. Tissue engineering involves cell growth on biomaterial scaffolds in vitro. These cells are then injected into cartilage defects for biological in vivo regeneration of the cartilage tissue. This review aims first to provide a brief introduction to the types of materials in medicine (biomaterials), to their roles in treatment of diseases, and to design factors and general requirements of biomaterials. Then, it attempts to sum up the recent advances in engineering articular cartilage; one of the most challenging area of study in biomaterials based tissue engineering, as an example to the research on regenerative solutions to musculoskeletal problems with an emphasis on the biomaterials that have been developed as scaffolds for cartilage tissue engineering. The definitive goal on cartilage regeneration is to develop a system using biomimetic approach to produce cartilage tissue that mimics native tissue properties, provides rapid restoration of tissue function, and is clinically translatable. This is obviously an ambitious goal; however, significant progress have been made in recent years; and further advances in materials design and technology will pave the way for creating significantly custom-made cellular environment for cartilage regeneration.

    Konca, Erkan/0000-0001-8943-091X; TUR, KAZIM/0000-0002-8017-8209The interest in austempered ductile irons (ADI) is continuously increasing due to their various advantageous properties over conventional ductile irons and some steels. This study aimed to determine the roles of alloying elements Ni, Cu, and Mo, on the austemperability of GGG-60 ductile cast iron. Two different sets of GGG-60 (EN-GJS-600-3) samples, one set alloyed with Ni and Cu and the other set alloyed with Mo, Ni, and Cu, were subjected to austempering treatments at 290 degrees C, 320 degrees C, and 350 degrees C. A custom design heat treatment setup, consisting of two units with the top unit (furnace) serving for austenitizing and the 200 L capacity bottom unit (stirred NaNO2-KNO3 salt bath) serving for isothermal treatment, was used for the experiments. It was found that austempering treatment at 290 degrees C increased the hardness of the Ni-Cu alloyed GGG-60 sample by about 44% without causing a loss in its ductility. In the case of the Mo-Ni-Cu alloyed sample, the increase in hardness due to austempering reached to almost 80% at the same temperature while some ductility was lost. Here, the microstructural investigation and mechanical testing results of the austempered samples are presented and the role of alloying elements (Mo, Ni, and Cu) on the austemperability of GGG-60 is discussed

    No full text
    In this study, a hand-held spectrophotometer was designed by taking advantage of the developments in modern optoelectronic technology. Spectrophotometer devices are used to determine the color information from the optic properties of the materials. As an alternative to a desktop spectrophotometer device we have implemented, it is the first prototype, low cost and portable. The prototype model designed for the textile industry can detect the color tone of any fabric. The prototype model consists of optic sensor, processor, display floors. According to the color applied on the optic sensor, it produces special frequency information on its output at that color value. In Arduino type processor, the frequency information is evaluated by the program we have written and the color tone information between 0-255 ton is decided and displayed on the screen

    Evolution of Aluminium Melt Quality of A356 After Several Recycling

    TUR, KAZIM/0000-0002-8017-8209; Dispinar, Derya/0000-0001-9550-6933Recyclability is one of the great features of aluminium and its alloys. However, it has been typically considered that the secondary aluminium quality is low and bad. This is only because aluminium is so sensitive to turbulence. Uncontrolled transfer and handling of the liquid aluminium results in formation of double oxide defects known as bifilms. Bifilms are detrimental defects. They form porosity and deteriorate the properties. The detection and quantification of bifilms in liquid aluminium can be carried out by bifilm index measured in millimetres as an indication of melt cleanliness using Reduced Pressure Test (RPT). In this work, recycling efficiency and quality change of A356 alloy with various Ti additions have been investigated. The charge was recycled three times and change in bifilm index and bifilm number was evaluated. It was found that when high amount of Ti grain refiner was added, the melt quality was increased due to sedimentation of bifilms with Ti. When low amount of Ti is added, the melt quality was degraded.Research Fund of the Istanbul Technical University [MOA-2019-42309]This work was supported by Research Fund of the Istanbul Technical University.

    Explaining Nadir Shah: Kingship and Royal Legitimacy in Muhammad Kazim Marvi's <i>Tārīkh-i ‘ālam-ārā-yi Nādirī</i>

    No full text
    One of the most important contemporary Persian prose chronicles of Nadir Shah's life is the Tārīkh-i ‘ālam-ārā-yi Nādirī (The World-Illuminating History of Nadir). Its author, Muhammad Kazim Marvi, served Nadir as a financial officer, and appears to have witnessed many of the events that he depicts. Completed after Nadir's death in 1160/1747 but before the last Afsharid ruler fell in 1210/1796, the AAN offers one of the most detailed contemporary accounts of Nadir's career. Several scholars, including N. D. Miklukho-Maklai and Muhammad Amin Riyahi, have begun to investigate the historical context of the work, discussing such issues as the date of its composition and its relationship to other accounts of the period. This article will attempt to build upon their work by focusing on what Muhammad Kazim's account of Nadir's career may reveal about his views on kingship and legitimacy.</jats:p

    The Spousal Abuse in Mary Wollstonecraft's The Wrongs of Woman, or Maria

    No full text
    Abstract: The spousal abuse is a form of abusive and aggressive actions that woman encounters in her close relationship with her male partner who attempts to uphold control and power over his spouse. This subject has increased widely nowadays and it needs to be investigated through the lens of literature in order to give a voice for the voiceless wives who endure the bad temper and abuse of their spouses. It will be studied in The Wrongs of Woman which is considered as a feminist novel and one of the best 18th century novels. Wollstonecraft’s philosophical and gothic tale tells the story of Her husband has committed her to an insane asylum. It critiques the oppressive sacredness of getting married in eighteenth-century Britain, and also the judicial framework that upholds it, according to Wollstonecraft., and focuses on society rather than individual female wrongdoings. The purpose of this dissertation is to utilize a thematic method to evaluate the theme of spousal abuse of women in the novel, and to investigate the impact and consequences on the main female characters. Her novel , was designed to be read and appreciated as both profoundly restorative and historical important in terms of what that exposes concerning patriarchal and patriarchal systems’ effects on women’s lives. Keywords: Spouse Abuse, Maria, or the Wrongs of Woman, Offending Theory, Mary Wollstonecraft.

    The effects of European Union illegal immigration policies on the candidate countries: the case of Turkey

    No full text
    Fighting against illegal immigration consumes a country’s financial sources which may lead to economic crisis; not fighting against illegal immigration, on the other hand, causes the emergence of identity and social fears. In other words, the struggle against illegal immigration not only costs a lot, but also poses risk in political terms to the countries that are involved in this process. Consequently, the illegal immigration policies could have the potential of ending in deadlock and becoming the reason of conflict between the related countries. This study examines the nature of relationship between the EU and Turkey in terms of illegal immigration policies. It also investigates to what extent Turkey carries out its responsibilities to the EU regarding the fight against illegal immigration. This study also examines whether or not the EU is rightful about its allegations against Turkey on the issue of illegal immigration. This study uses the following mixed method: The Content Analysis and Candidate Countries’ Eurobarometers (CCEB) Surveys. The data used in content analysis are obtained from the EU Reports and Turkish Adaptation to Acquis Documents. The statements in the documents were coded on the basis of Turkey’s progression status with a special focus on the topics. Another method used in the study is the CCEB Surveys obtained from the website of Interuniversity Consortium for Political and Social Research (ICPSR). These surveys were conducted in 2006 and 2007 in the EU member countries and candidate countries. The sample size of each survey was around 30.000. According to the results of the content analysis, Turkey made adequate progress in the following two fields: Fighting against illegal immigration and human trafficking. Turkey made no progress in repealing the geographical limitation. Turkey makes limited or inadequate progress in nine fields including signing and ratifying readmission agreement, handling asylum-seekers and refugees, developing training programs, setting up and improving the reception and removal centers, setting up a migration and asylum authority, alignment to external border policy and Schengen Agreement, setting up an integrated border management unit, setting up a unified and professional border guard and aligning to the EU Visa Policy. These inadequate progresses show that Turkish policy on illegal immigration is fluctuated and reluctant. According to the results of the Logistic Regression Analysis, the citizens of destination countries give almost three times higher priority on illegal immigration than the citizens of non-destination countries. Turkish citizens thinks that the EU should take collective responsibility on immigration policies, otherwise, they see the immigration as a risk for future integration to the EU. Turkish citizens are also less likely to support the joint EU efforts and they perceive immigration issues significantly less important than the citizens of destination countries. On the other hand, Turkey do not completely ignore the importance of fighting against illegal immigration. The citizens of non-destination countries are more likely to think that the EU should take further joint-responsibility on immigration issues. In fact, the perception of importance of illegal immigration and perceived risks for integration confirm that the citizens of non-destination countries regard the immigration issue as a responsibility of the EU. In conclusion, Turkey purposefully fights against illegal immigration in a limited way as it costs a lot and politically risky. Although illegal immigration is the problem of destination countries (Core EU countries), non-destination countries support destination countries on their fight against illegal immigration as well. Turkey prioritizes the problem but seems to be reluctant to take necessary actions. The EU and Turkey are in deadlock in terms of negotiations for fighting against illegal immigration in a full-fledged way.Ph.D.Includes bibliographical referencesby Kazim Ciri
