White Engineering Corporation to constructits first international civilian airport, Istanbul'sYe & scedil;ilk & ouml;y Airport. As this article will argue, the buildingof Ye & scedil;ilk & ouml;y (1949-53), through a partnership with two American engineering firms, is essentially anearly Cold War narrative of transnational exchange involving the multidirectional flow of technicalknowledge, expertise and resources between the United States and Turkey; the circulation of geopol-itically significant (and frequently competing) military, civilian and government actors; and thelocal and global implications of these transmissions. Yet the Ye & scedil;ilk & ouml;y construction narrative also illus-trates how post-war technology transfer was a highly political process of constant adaptation, modifi-cation and negotiation. Fraught with unforeseen friction and thorny challenges, Ye & scedil;ilk & ouml;y exemplifiesthe complicated American Cold War strategy of creating and maintaining alliances through engineeringknowledge, personnel and practices, often with unintended consequences. Moreover, as a case study,Ye & scedil;ilk & ouml;y opens a new window into the cautious science diplomacy that occurred along the IronCurtain, while filling a notable historiographic gap with respect to aviation in early Cold War Turkey.Conference Object Exercise Capacity and Activities of Daily Living in Ccpd Patients With Mild and Higher Symptom Scores(European Respiratory Soc Journals Ltd, 2024) Eyuboglu, Filiz; Saglam, Melda; Vardar-Yagli, Naciye; Calik-Kutukcu, Ebru; Coplu, Lutfi; Arikan, Hulya; Inal-Ince, Deniz[No Abstract Available]Article Citation - WoS: 9Citation - Scopus: 9Fluorescent and Electrochemical Detection of Nuclease Activity Associated With <i>streptococcus Pneumoniae</I> Using Specific Oligonucleotide Probes(Royal Soc Chemistry, 2024) Goikoetxea, Garazi; Akhtar, Khadija-Tul Kubra; Prysiazhniuk, Alona; Borsa, Baris A.; Aldag, Mehmet Ersoy; Kavruk, Murat; Hernandez, Frank J.Streptococcus pneumoniae (S. pneumoniae) represents a significant pathogenic threat, often responsible for community-acquired pneumonia with potentially life-threatening consequences if left untreated. This underscores the pressing clinical need for rapid and accurate detection of this harmful bacteria. In this study, we report the screening and discovery of a novel biomarker for S. pneumoniae detection. We used S. pneumoniae nucleases as biomarker and we have identified a specific oligonucleotide that works as substrate. This biomarker relies on a specific nuclease activity found on the bacterial membrane, forming the basis for the development of both fluorescence and electrochemical biosensors. We observed an exceptionally high sensitivity in the performance of the electrochemical biosensor, detecting as low as 10(2) CFU mL(-1), whereas the fluorescence sensor demonstrated comparatively lower efficiency, with a detection limit of 10(6) CFU mL(-1). Moreover, the specificity studies have demonstrated the biosensors' remarkable capacity to identify S. pneumoniae from other pathogenic bacteria. Significantly, both biosensors have demonstrated the ability to identify S. pneumoniae cultured from clinical samples, providing compelling evidence of the potential clinical utility of this innovative detection system.Article Reevaluation of Plate-Fin Heatsink Natural Convection Correlations for Sideways and Three-Dimensional Inclinations(Taylor & Francis inc, 2025) Mehrtash, MehdiThe common orientations of the plate-fin heat sink for natural convection cooling of electronics are vertical and upward-facing horizontal. However, depending on various use scenarios, the heat sink may be inclined, intentionally or otherwise. In our previous papers concerning this subject, the author proposed a set of correlations for plate-fin heat sinks covering all inclination angles backward and forward (pitch rotation) from the vertical position of the heat sink. The set was based on a series of computational simulations with a validated model. At the time, tilting the heat sink sideways (roll rotation) was not considered. In the present study, though, the sideways inclination of the plate-fin heat sinks is simulated using our previous model only by adjusting the direction of the gravitational acceleration vector, thus requiring no additional validation. It is determined that the previously proposed correlation is valid up to 80 degrees sideways inclinations of the heat sink. Interesting flow structures are observed when the heat sink is tilted 90 degrees sideways. Furthermore, it is demonstrated that the correlation surprisingly remains valid if the heat sink is simultaneously rotated in both axes (pitch and roll).Book Part Religion, Education, and the Turkish Constitution: a Critical Assessment(Ashgate Publishing Ltd, 2013) Köker,L.; Koeker, Levent[No abstract available]Conference Object Citation - WoS: 4Citation - Scopus: 3Dual-Frequency, Two Shorting Pin-Loaded Equilateral Triangular Patch Antennas(Electromagnetics ACAD, 2012) Can,S.; Kapusuz,K.Y.; Aydin,E.This study presents the resonant frequencies of several antennas, which are dual-frequency antennas. These antennas possess two shorting pins to form dual frequency. Among several methods to provide dual operation, two shorting pins are used to form dual frequency equilateral triangular antennas since there are limited studies on this issue and higher frequency ratios are achievable. The present study has been done with this in mind in order to contribute to related literature on such antennas. Here, the parameters that affect the resonant frequencies of the antenna are also evaluated. The thickness, side length, and shorting pin positions are changed numerous times, and the resonant frequencies are examined according to the change of these parameters. Finally, the frequency ratios are determined for each variation, and the results are compared. The proposed antennas in present study achieved a frequency ratio around 5.7, which is significantly higher from the ones presented in the literature.Article Citation - WoS: 4Optimum Dragline Selection for Strip Coal Mines(inst Mining Metallurgy, 1998) Erdem, B; Çelebi, N; Pasamehmetoglu, AGA model is presented by means of which the optimal dragline selection may be made. An outline is given of the methodology that was adopted in developing a series of generic algorithms to first define and then formularize the need to extend the working bench under a nat-lying topography and coal seam. Rehandle percentages were calculated for four generalized extended bench geometries, in each of which the percentage rehandle varied according to the relative positions of the extended bench and pit. A set of geometric and simulative equations was developed on which a model for the optimal selection of a dragline was based. Finally, a typical application was tested through the use of data associated with a hypothetical strip-mining operation.
