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
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. In order ...Daha fazlası
Throughout the history of English Language Teaching, teaching grammar has been one of the most important concepts. Different approaches, methods and techniques have been put forward regarding different ways of teaching grammar. Discovery learning and integrating grammar teaching with reading are among these ways through which English grammar can be taught. This study was conducted to test the effectiveness of a group reading instruction technique as an alternative to the traditional application of explicit teaching at a private university in Turkey. The study was carried out as an experimental ...Daha fazlası
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
Bu çalışmada, karaciğer fokal lezyonlarının türünün belirlenmesinde uzmanların karar vermelerini kolaylaştırmak amacıyla T1 ağırlıklı, dinamik kontrastlı karaciğer manyetik rezonans (MR) görüntülerinin farklı fazları dalgacık tabanlı görüntü füzyonu uygulanarak birbirleriyle kombine edilmiştir. Kullanılan veriler, hepatoselüler karsinom (HCC), kolanjioselüler karsinom (CCC), fokal nodüler hiperplazya (FNH), metastaz, kist ve hemanjiyom olmak üzere 6 farklı fokal lezyon türüne göre etiketlenmiştir. Uygulamada, 30 farklı hastadan, kontrast öncesi, arteryal, portal venöz ve geç venöz olmak üzere ...Daha fazlası
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.

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
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
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
In this letter, we propose a novel method for unsupervised change detection in multitemporal multispectral Landsat images using multiobjective evolutionary algorithm (MOEA). The proposed method minimizes two different objective functions using MOEA to provide tradeoff between each other. The objective functions are used for evaluating changed and unchanged regions of the difference image separately. The difference image is obtained by using the structural similarity index measure method, which provides combination of the comparisons of luminance, contrast, and structure between two images. By ...Daha fazlası
Energy needs are increasingly growing due to the mechanization of industry by the industrial revolution, increased production in line with increased population, higher prosperity levels, and abundance of electrical tools. Mineral oil get polluted chemically and physically and become unusable after a certain amount of usage. As natural resources are limited, mineral waste oil need to be recycled in order to reduce production costs and achieve sustainable energy acquisition. Cement factories are energy-intensive businesses and among industries that have the highest needs for energy. With usage o ...Daha fazlası

Variations in temperature and precipitation have direct impacts on the physical, chemical and biological characteristics of the shallow lakes. This paper examines the possible linkages between climate variables and the water levels of shallow interconnected Lakes Mogan and Eymir, located 20 km south of Ankara in Central Anatolia. The variations in the lakes' water levels during 1996-2015 are studied and the impacts of climate variables on the lake levels are assessed to address the long-term consequences. The nonparametric Mann-Kendall test was used to quantify trends in the climate variables ...Daha fazlası
