A Turkish Posthumanist Perspective in Science Fiction: Özlem Ada’s Embriyogenesis
No full textThe world of science-fiction in Turkey is like a closed circuit, only supported by fans and authors, but an outstanding example, Özlem Ada's Embriyogenesis (1997), provides the reader with a unique experience in the two stories titled "Hisse Senetleri" and "Çaya Yetiştirilir," which can be respectively translated as "Share Certificates" and "You Can Be Ready for Tea Party." Both stories are analyzed in this paper with an ecocritical approach to science-fiction as regards how this genre plays a crucial role in broadening the horizons of ecocriticism. The posthumanist perspective of the author offers the reader a chance to interrogate how traditional science-fiction uses apocalyptic and complacent modes to create futuristic images of the world. Ada's stories are exceptional to the Turkish science-fiction genre as they are environmentally oriented
Molar volume calculated at various pressures and the Pippard relations close to the melting point in benzene
No full textTarı İlgin, Özlem (Arel Author)The molar volume of solid and liquid benzene was calculated at various pressures (at constant temperatures), and the Pippard relations were examined close to the melting point in this organic molecule. The molar volume calculated is in good agreement with the observed data, which decreases as the pressure increases up to about 150 MPa. The Pippard relations are also valid within this pressure range at constant temperatures studied here for the solid and liquid phases of benzene
Bubbles in the Middle East stock markets
No full textTaşseven, Özlem (Dogus Author)We empirically investigate the existence of periodically collapsing bubbles in seven Middle East and North African (MENA) financial markets for the period ending in May 2009. We use the Taylor and Peel (1998) residual augmented least square Dickey and Fuller test (RALS DF) to detect the bubbles. We find that the hypothesis of a bubble formation cannot be rejected for all seven markets investigated in our study, leading us to believe that in fact there has been a break down in the cointegration relationship between real equity prices and real dividends and also between real market capitalizations and real dividends
Toplu Beslenme Sistemlerinde El Hijyeninin Önemi
No full textPersil Özkan, Özlem (Arel Author)Besinler, üretim zincirindeki çeşitli aşamalarda kontamine olabilirler. Toplu beslenme üretimi ve servisi yapan iş yerlerinde personel hijyeninin sağlanması birçok besin kaynaklı hastalığın önlenmesinde etkili olabilmektedir. Eller ve besinle teması olabilen vücut bölgelerinin temizliği bu bakımdan oldukça önemlidir. Besinlerin eller yoluyla kontaminasyon riski çok yüksektir. Toplu beslenme yapılan kurumlarda besinlerin hazırlanması ve servisinde çalışan personelin kişisel ve mutfak hijyeni konusunda eğitimli ve bilgili olması insan sağlığının korunması ve sürdürülmesi açısından vazgeçilmezdir
Nowcasting capacity utilization in Turkey: A continuous wavelet analysis
No full textTaşseven, Özlem (Dogus Author)Capacity utilization in macroeconomics is always related to inflation rate and unemployment level. However, the Great Recession has taught us that there might have been other factors considered in determining and/or be determined by capacity utilization. In order to further enhance Phillips Curve relationship unconventional variables such as financial and survey variables are considered. The relationship between capacity utilization rates and several real variables such as industrial production, gross domestic product growth rate, unemployment rate, consumer expenditures, financial variables such as return on BIST 100 index, exchange rate of currency basket, interest rates, survey variables such as consumer consumption index, business tendency survey and survey of expectations is investigated using data between 2006 and 2015 for Turkey. All of the above-mentioned variables indicate the production capacity and their repercussions on other macro variables except the level of standard of living. We also highlight the repercussions of production capacity concerning welfare state
Seismic performance of a high-rise building by using linear and nonlinear methods
No full textIn this paper, the seismic behavior of the existing reinforced concrete tall building is investigated by using the linear and nonlinear dynamic methods. The selected existing reinforced concrete structure was designed according to Turkey Seismic Code-2007. The performance analysis according to the Turkey Building Earthquake Code-2019 is realized in a 41-story reinforced concrete shear wall-framed structure in Istanbul where active fault lines are located. For high-rise building, firstly, spectrum analysis according to mode superposition methods of linear computational methods used within the scope of strength-based design is performed. Turkey Building Earthquake Code-2019 advises a nonlinear deformation-based design approach to determine more accurately the behavior of high-rise building, as in the earthquake regulations of other developed countries. In addition, the nonlinear time history analyses of building were performed. At the end of the study, torsional irregularity is seen on the normal floors and intermediate floor; stiffness irregularity was found on second floors. In addition, it has been observed in some of the oblique columns of the building that load bearing capacities were exceeded due to creep, axial compressive loads and severe damages occurred. According to the Turkey Building Earthquake Code-2019, the high-rise reinforced concrete shear wall building is not expected to satisfy life safety performance levels under design earthquake. © 2022, The Author(s), under exclusive licence to Springer Nature B.V.WOS:00075157610000
New spirobifluorene-based hole-transporting semiconductors for electroluminescent devices
No full textWOS: 000342180200015A series of spirofluorene-centered, carbazole and thiophene-linked molecules (CFT, TCFT and CFTFC) were synthesized by Ullmann coupling and Suzuki cross-coupling reactions, and fully characterized by H-1 NMR, C-13 NMR, FT-IR, UV-vis, PL spectroscopy, DSC, TGA, CV and MALDI-TOF. Multilayer organic light-emitting diode (OLED) devices based on these materials were fabricated to investigate their hole-transport properties. The electroluminescent properties of these molecules showed excellent performance in the devices. CFT-based OLED devices exhibited the best performance with a low turn on voltage of 3 V, a maximum luminance of 10 100 cd m(-2) and a maximum luminous efficiency of 11.30 (cd A(-1)). This work brings opportunities for the employment of spirobifluorene semiconductors for use in highly efficient OLED applications.Mugla Sitki Kocman University (BAP Project)Mugla Sitki Kocman University [2012/138]The author would like to thank Prof. Niyazi Serdar Sariciftci for providing research facilities for device fabrication and characterization at the Linz Institute for Organic Solar Cells.

Calculation of the Raman frequencies as a function of temperature in phase I of benzene
No full textTarı, Özlem (Arel Author)This study gives our calculation of the Raman frequencies of the lattice modes A (A1g), B (AgB2g) and C (B1gB3g) as a function of temperature at constant pressures of 0, 1.4 and 3.05 GPa for the solid phase I of benzene. The Raman frequencies of those lattice modes are calculated using the volume data from the literature through the mode Grüneisen parameters for the solid phase I of this molecular crystal. It is shown here that the Raman frequencies of the lattice modes studied decrease with increasing temperature, as expected and they also decrease as the pressure increases in the solid phase I of benzene
