Çimento İle Stabilizasyonda Optimum Çimento Oranının Belirlenmesi

URAY, Esra | SANCIOĞLU, Sadrettin | ÇUBUKÇU, Esra Aslı | ERDEM, Mehmet Doğukan

Bu çalışmada, farklı çimento ve su oranlarının çimento stabilize zemin dayanımına etkisi deneysel olarak araştırılmıştır. Zayıf zeminin iyileştirilmesi ve belirli zemin özelliklerini sağlaması karayolu uygulamalarında önemli bir konudur. Yol yapımında kullanılan çimento bağlayıcılı granüler temel tabakası çakıl ve ya kırmataş dolgu malzemesi kullanılarak elde edilmektedir. Yol maliyeti ve hizmet ömrü açısından yol altı temel tabakası gerekli dayanımı sağlamalı ve oturmalara karşı dayanıklı olmalıdır. Çimento stabilizasyonunda, taneler arası boşluklar doldurulur ve zeminin mukavemeti arttırılır ...Daha fazlası

Çocuğa İsim Verme ve İsim Değişikliği Durumunda Hâkimin Çocuğa İsim Verme Yetkisi

GÜLEŞ, Bedia

İsim kişinin toplum içerisindeki resmi ve sosyal kimliğidir. Kişinin ismi için kural, onun değişmezliğidir. Fakat bazı durumlara mahsus olmak üzere mahkemeden değiştirilmesi talep edilebilir. Çocuğun ismini verme yetkisi Türk Medeni Kanunu m.339’a göre ana – babasına aittir ve bir görüşe göre onun değiştirilmesini isteme yetkisi de yine onlara aittir. Bu arada ana – babanın birlikte sahip oldukları bu yetkinin velayete mi yoksa soy bağına mı dayandığı hususu da tartışmalıdır. Dayanağı her ne olursa olsun, acaba ana – babanın çocuğa isim verme konusunda anlaşmazlığa düştüğü durumlarda hâkim onl ...Daha fazlası

D-meson production in p-Pb collisions at √sNN = 5.02 TeV and in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

In the context of the investigation of the quark gluon plasma produced in heavy-ion collisions, hadrons containing heavy (charm or beauty) quarks play a special role for the characterization of the hot and dense medium created in the interaction. The measurement of the production of charm and beauty hadrons in proton– proton collisions, besides providing the necessary reference for the studies in heavy-ion reactions, constitutes an important test of perturbative quantum chromodynamics (pQCD) calculations. Heavy-flavor production in proton–nucleus collisions is sensitive to the various effects ...Daha fazlası

Elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity (|y| < 0.7) is measured in Pb–Pb collisions at √sNN = 2.76 TeV with ALICE at the LHC. The particle azimuthal distribution with respect to the reaction plane can be parametrized with a Fourier expansion, where the second coefficient (v2) represents the elliptic flow. The v2 coefficient of inclusive electrons is measured in three centrality classes (0–10%, 10–20% and 20–40%) with the event plane and the scalar product methods in the transverse momentum (pT) intervals 0.5–13GeV/c and 0.5–8GeV/c, respectively.

The Impact Of Paris Agreement on Turkish Coal Power Project Developments

UYANIK, Sırrı | ALTÜRK, Orhan

EuraCoal, a European mining industry lobby group, estimates that Turkey has around 1.3 billion tonnes of hard coal and 11.5 billion tonnes of lignite resources, of which 0.5 billion tonnes and 9.8 billion tonnes respectively are proven reserves. As worldwide populations and industrial growth reach new heights, electricity demand is projected to increase substantially. Fossil fuels, particularly coal, will continue to be a vital energy source for the power sector in many countries. At the same time, fossil fuel fired power generation is one of the largest sources of global CO2 emissions. High-e ...Daha fazlası

Import Dependency And Seeking For New Energy Technologies European Union Case

ÖZKAN NESİMİOĞLU, Şerife

In this paper, energy poverty and as a result of this energy import dependency and its possible negative results have been examined by taking European Union (EU) into consideration. This analysis has two aims: the first one is questioning the European Unions’ energy security from supply perspective and the second one is investigating the solutions produced by European Union to get away or at least to reduce its energy import dependency. To guarantee its energy supply security at affordable price and to attain its targets about energy security, some action plans has been being put into practice ...Daha fazlası

Search for weakly decaying

KARASU UYSAL, Ayben | ALICE Collaboration

We present results of a search for two hypothetical strange dibaryon states, i.e. the H-dibaryon and the possible !n bound state. The search is performed with the ALICE detector in central (0–10%) Pb– Pb collisions at √sNN = 2.76 TeV, by invariant mass analysis in the decay modes !n → dπ+ and Hdibaryon → !pπ−. No evidence for these bound states is observed. Upper limits are determined at 99% confidence level for a wide range of lifetimes and for the full range of branching ratios. The results are compared to thermal, coalescence and hybrid UrQMD model expectations, which describe correctly the ...Daha fazlası

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The elliptic flow, v2, of muons from heavy-flavour hadron decays at forward rapidity (2.5 < y < 4) is measured in Pb–Pb collisions at √sNN = 2.76 TeV with the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee–Yang zeros methods are used. The dependence of the v2 of muons from heavy-flavour hadron decays on the collision centrality, in the range 0–40%, and on transverse momentum, pT, is studied in the interval 3 < pT < 10 GeV/c. A positive v2 is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10–20% and 20–40% cen ...Daha fazlası

Centrality dependence of pion freeze-out radii in Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on the measurement of freeze-out radii for pairs of identical-charge pions measured in Pb-Pb collisions at √sNN = 2.76 TeV as a function of collision centrality and the average transverse momentum of the pair kT. Three-dimensional sizes of the system (femtoscopic radii), as well as direction-averaged one- dimensional radii are extracted. The radii decrease with kT, following a power-law behavior. This is qualitatively consistent with expectations from a collectively expanding system, produced in hydrodynamic calculations. The radii also scale linearly with ⟨dNch/dη⟩1/3. This behavior ...Daha fazlası
