    The integration of tall buildings in Urban environment: considering the key sustainability concepts

    Get PDF
    As a result of physical, social and economic needs, demand for tall buildings is increasing worldwide. Due to their great size and large impacts on urban environment, tall buildings,, have the potential to improve the quality around them through careful design and urban integration. When compared with lower buildings, tall buildings can be more challenging by means of architectural design and engineering details. Also, depending on their large area of influence, design considerations regarding sustainability and environmental integration of tall buildings need to be handled with more care than other conventional buildings in order to provide the most positive impact

    When does globalization lead to local adaptation? the emergence of hybrid Islamic schools in Turkey, 1985-2007

    Get PDF
    Institutional perspectives of globalization envision the homogenization of the world through global cultural, economic, and political dynamics, while glocalization theory highlights how local cultures may adapt or resist global forces. On the basis of these theories, the authors analyze when, where, and why local hybrid organizational forms emerge as a reaction to globalization. They suggest that the impact of globalization on the emergence and expansion of hybrid organizational forms, which reflect local adaptations of global forms, depends on three types of moderators: (1) the fit between global and local ideas, values, and practices; (2) the experience of the local community with alternative organizational forms; and (3) the motivation of the local community to adapt. The authors test their hypotheses with data from the high school education system in Turkey from 1985 to 2007, a period in which Turkey experienced the growing impact of globalization

    Syntheses of wholly natural polymeric linseed oil (PLO) containing peroxide groups have been reported. Peroxidation, epoxidation and/or perepoxidation reactions of linseed oil, either under air or under oxygen flow at room temperature, resulted in polymeric peroxides, PLO-air and PLO-ofl, containing 1.3 and 3.5 wt.% of peroxide, with molecular weights of 2100 and 3780 Da, respectively. PLO-air contained cross-linked film up to 46.1 wt.% after a reaction time of 60 d, associated with a waxy, soluble part (PLO-air-s) that was isolated with chloroform extraction. PLO-ofl was obtained as a waxy, viscous liquid without any cross-linked part at the end of 24 d under visible irradation and oxygen flow. Polymeric peroxides, PLO-air-s and PLO-ofl initiated the free radical polymerization of both methyl methacrylate (MMA) and styreine (S) to give PMMA-graft-PLO and PS-graft-PLO graft copolymers in high yields with M-w varying from 37 to 470 kDa. The polymers obtained were characterized by FT-IR. H-1 NMR, TGA, DSC and GPC techniques. Cross-linked polymers were also studied by means of swelling measurements. PMNA-graft-PLO graft copolymer film samples were also used in cell-culture studies. Fibroblast cells were well adhered and proliferated on the copolymer film surfaces, which is important in tissue engineering

    The effect of granulocyte colony stimulating factor on genotoxicity in allogeneic peripheral blood stem cell transplantation donors: A prospective case-control study

    Background. Every year, thousands of donors are exposed to granulocyte-colony stimulating factor (G-CSF) for stem cell mobilization in hematopoietic stem cell transplantations (HSCT). Previous studies about the genotoxicity of G-CSF were inconclusive. In this study, the genotoxic effects of G-CSF in peripheral blood stem cell (PBSC) donors were evaluated prospectively by using three different validated and reliable methods for the first time in the literature to the best of our knowledge. Methods. Donors of PBSC transplantation (n=36), who received G-CSF were evaluated for genotoxicity by micronucleus test (MNT), nuclear division index (NDI), and comet assay (CA). Genotoxic effects are expected to cause an increase in MNT and CA values and decrease in NDI. Blood samples were collected at three time-points (TP): before starting G-CSF (TP1), after G-CSF for five days (TP2), and one month after the last dose (TP3). Sixteen controls were included for baseline comparison of genotoxicity tests. CD34 cell counts and hemograms were also analyzed. Results. MNT and CA parameters; comet and tail length, tail DNA%, and tail moment, showed no change in time whereas another CA parameter, Olive’s tail moment (OTM) was increased significantly at TP3 compared to both baseline and TP2 (p=0.002 and p=0.017, respectively). Nuclear division index decreased significantly at TP2 (p[removed]Ankara University Scientific Study Fun

    Devlet ve vakıf üniversitelerinde "strateji", 1982-2014 ("Strategy" in public and private universities, 1982 - 2014)

    Bu çalışmada, üniversitelerin, öğretim alanlarında çeşitlenme şeklinde ele aldığımız, stratejileri üzerindeki kurumsal etkileri inceliyoruz. Türkiye’de 1982-2014 yılları arasında faaliyette bulunmuş bütün üniversiteleri kapsayan bir veri temeliyle, devlet ve vakıf üniversitelerinin stratejilerinin mensubu oldukları topluluktaki stratejilerin ortalamasını izlediğini gösteriyoruz. Bulgularımız, ilave olarak, bu kurumsal etkinin her topluluk içindeki üniversitelerin stratejilerinde farklılaşmanın ve yükseköğretim alanındaki rekabetin artması ile zayıfladığını ortaya koymaktadır. Ayrıca, rekabetin zayıflatıcı etkisi vakıf üniversitelerinde daha güçlüdür. Makale, bulgularımızın kurumsalcı yazın ve Türkiye’deki yükseköğretim alanı için ne ifade ettiği ve neler düşündürdüğünün tartışılmasıyla son bulmaktadır

    La mission 2016 de Labraunda s’est déroulée du 10 juillet au 17 septembre 2016. Les événements politiques turcs qui se sont déroulés peu après le début des opérations, s’ils ont eu un certain impact sur la fouille, avec notamment le renoncement de quelques participants, n’ont toutefois pas désorganisé les travaux prévus. Dans la lignée des années précédentes, nous avons travaillé, avec succès, d’une part à la consolidation de notre implantation locale, par des accords de collaboration (avec l..

    La mission Labraunda 2013 s’est déroulée du 05 août au 27 septembre 2013. La date de début, initialement prévue le 22 juillet, a dû être reportée à deux reprises suite à des difficultés administratives. Les opérations 2013 se sont déroulées sous l’égide du Musée archéologique de Milas, en cette période de transition de la direction du site, et nous sommes particulièrement redevable à Mr Ali Sinan Özbey, directeur du Musée, et à son représentant Suleyman Özgen pour l’aide et le soutien qu’ils ..

    La saison 2014 à Labraunda (Fig. 1) a probablement été la plus intense depuis les grands travaux entrepris par l’équipe suédoise sous la direction d’Alfred Westholm en 1960. Grâce au soutien des très nombreuses institutions, publiques comme privées, et de personnalités physiques, nous avons pu réunir sur le terrain une équipe internationale de 47 chercheurs et étudiants de onze nationalités différentes (d’Ouest en Est : États-Unis, Colombie, Royaume-Uni, France, Suède, Finlande, Slovaquie, Gr..
