Doğrudan Yabancı Sermaye Yatırımları ve Büyüme İlişkisi: 2008 Krizi Sonrası Türkiye Uygulaması

AFŞAR, Bilge | CURA, Fatih | DEMİRHAN, Faruk

Sanayi devriminden sonra iktisadi olarak üretim faktörlerindeki önemlilik derecesi değişmiştir. Sermaye ve emek faktörünün önemi daha ön plana çıkmıştır. Sermaye daha çok kar sağlayacağı bölgelere yönelmeye başlamış, ülkeler ise ekonomik büyümelerini ve refah düzeyini yükseltmek amacıyla sermayeyi kendi ekonomilerine çekmeye çalışmıştır. Bu döngü günümüzde küreselleşmenin de etkisiyle daha hızlı ve esnek hale gelmiştir. Ticari anlamda sınırlar kalkmış dünya sermaye sahipleri için tek bir ülke gibi görülmeye başlanmıştır. Sermaye sahipleri geçmişte olduğu gibi günümüzde de ekonomik ve siyasi is ...Daha fazlası

EKİCİ, Gamze | SAYIN, Ülkü | IŞIK, İlker | ÖZMEN, Ayhan | KILIÇ, Hamdi Şükür

In this study paramagnetic centers in quartz minerals of Kumyer Location archeological samples were identified using Electron Spin Resonance (ESR) technique. ESR spectra were recorded at different microwave powers and various spectrometer temperatures with JEOL JESFa-300 X-band ESR spectrometer located in Selcuk University Advanced Technology Research and Application Center (İLTEK). It was determined that there is Al, Ti-Li, Ti-H and Ge paramagnetic centers which were produced by natural radiation in quartz minerals of ceramic samples and ESR parameters of these centers were measured.

Static analysis of laminated composite beams based on higher-order shear deformation theory by using mixed-type finite element method

ÖZÜTOK, Atilla | MADENCİ, Emrah

In this paper, mixed finite element (MFEM) equations which are based on a functional are obtained by using the Gâteaux differential (GD) for laminated composite beams. Higher-order shear deformation theory (HOBT) including non-linear distribution of shear stress through thickness of laminated beam is presented. Differential field equations of composite beams are derived from virtual displacement principle. These equations were trans- formed into the operator form and using the mathematical advantages of the proposed the variational method, a functional with geometric and dynamic boundary condi ...Daha fazlası

Housing Development In Turkey Since The Republic’s Announcement

BACAK, Fatma Nur

Housing is a physical space where man finds himself from the moment a person comes to the World, the first steps are taken in the development of personality and selfness, the rules of social relations and social values are acquired and reproduced. It is the most important place to eat, to sleep, to get personal needs, shortly, to live in [1]. From the former time to daily time, these places are changing and developing day by day with many effects such as living conditions, environmental conditions, political interactions, aesthetic, climate conditions and population increase.

Energy dependence of forward-rapidity J/ψ and ψ(2S) production in pp collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Abstract We present results on transverse momentum (pt) and rapidity (y) differential production cross sections, mean transverse momentum and mean transverse momen- tum square of inclusive J/ψ and ψ(2S) at forward rapid- ity (2.5 < y < 4) as well as ψ(2S)-to-J/ψ cross section ratios. These quantities are measured in pp collisions at cen- ter of mass energies √s = 5.02 and 13 TeV with the ALICE detector. Both charmonium states are reconstructed in the dimuon decay channel, using the muon spectrometer. A com- prehensive comparison to inclusive charmonium cross sec- tions measured at √s = 2.76, 7 ...Daha fazlası

J/ψ Elliptic Flow in Pb-Pb Collisions at sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report a precise measurement of the J=ψ elliptic flow in Pb-Pb collisions at sNN 1⁄4 5.02 TeV with the ALICE detector at the LHC. The J=ψ mesons are reconstructed at midrapidity (jyj < 0.9) in the dielectron decay channel and at forward rapidity (2.5 < y < 4.0) in the dimuon channel, both down to zero transverse momentum. At forward rapidity, the elliptic flow v2 of the J=ψ is studied as a function of the transverse momentum and centrality. A positive v2 is observed in the transverse momentum range 2 < pT < 8 GeV=c in the three centrality classes studied and confirms with higher statistics ...Daha fazlası

K∗(892)0 and φ(1020) meson production at high transverse momentum in pp and Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of K∗(892)0 and φ(1020) mesons in proton-proton (pp) and lead-lead (Pb-Pb) collisions at √sNN = 2.76 TeV has been analyzed using a high luminosity data sample accumulated in 2011 with the ALICE detector at the Large Hadron Collider (LHC). Transverse momentum (pT) spectra have been measured for K∗(892)0 and φ(1020) mesons via their hadronic decay channels for pT up to 20 GeV/c. The measurements in pp collisions have been compared to model calculations and used to determine the nuclear modification factor and particle ratios. The K∗(892)0/K ratio exhibits significant reduction fro ...Daha fazlası

φ-Meson production at forward rapidity in p–Pb collisions at √sNN = 5.02 TeV and in pp collisions at √s = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The first study of φ-meson production in p–Pb collisions at forward and backward rapidity, at a nucleon– nucleon centre-of-mass energy √sNN = 5.02 TeV, has been performed with the ALICE apparatus at the LHC. The φ-mesons have been identified in the dimuon decay channel in the transverse momentum (pT) range 1 < pT < 7 GeV/c, both in the p-going (2.03 < y < 3.53) and the Pb-going (−4.46 < y < −2.96) directions — where y stands for the rapidity in the nucleon–nucleon centre-of-mass — the integrated luminosity amounting to 5.01 ± 0.19 nb−1 and 5.81 ± 0.20 nb−1, respectively, for the two data sam- ...Daha fazlası

Azimuthally differential pion femtoscopy in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present the first azimuthally differential measurements of the pion source size relative to the second harmonic event plane in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of sNN 1⁄4 2.76 TeV. The measurements have been performed in the centrality range 0%–50% and for pion pair transverse momenta 0.2 < kT < 0.7 GeV=c. We find that the Rside and Rout radii, which characterize the pion source size in the directions perpendicular and parallel to the pion transverse momentum, oscillate out of phase, similar to what was observed at the Relativistic Heavy Ion Collider.

Production of 4He and 4He in Pb–Pb collisions at √sNN = 2.76 TeV at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Results on the production of 4He and 4He nuclei in Pb–Pb collisions at √sNN = 2.76 TeV in the rapidity range | y |< 1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0–10% central events are found to be dN /dy4 He = (0.8 ± 0.4 (stat) ± 0.3 (syst)) × 10−6 and dN /dy4 He = (1.1 ± 0.4 (stat) ± 0.2 (syst)) × 10−6, respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (Tchem = 156 MeV) as for light hadrons. The measured ratio of 4He/4He is 1.4 ± 0.8 (stat) ± 0.5 (syst).
