Bu makale İslam dünyasında vakıfların ortaya çıkısından günümüzdeki en son gelişmelere kadar bu çok önemli kurumun geçirmiş olduğu evreleri incelemektedir. Ayrıca Bati dünyasındaki son durumlar da ele alınmakta ve sonuç olarak vakıfların hem ülkemizde hem de tüm İslam dünyasında ciddi bir reform surecine tabi tutulmaları gereği ortaya çıkmaktadır. This article examines waqfs and their evolution from their emergence in the Islamic world until the present day. In addition, it briefly looks at similar institutions in the contemporary West. It has been reached a conclusion that waqf institutions c ...Daha fazlası
The tradition of pious Islamic foundations goes back several centuries, they can be regarded as civil society organisations avant la lettre. After colonial politics and post-colonial modernisation efforts led to their demise in large parts of the Islamic world, they again gain in recognition in Muslim societies. But concrete legislation is necessary to support this trend.
In this Letter, we report the first measurement of the inelastic cross section for antideuteron-nucleus interactions at low particle momenta, covering a range of 0.3 ≤ p < 4 GeV=c. The measurement is carried out using p-Pb collisions at a center-of-mass energy per nucleon–nucleon pair of ffiffiffiffiffiffiffi sNN p ¼ 5.02 TeV, recorded with the ALICE detector at the CERN LHC and utilizing the detector material as an absorber for antideuterons and antiprotons. The extracted raw primary antiparticle-to-particle ratios are compared to the results from detailed ALICE simulations based on the GEANT ...Daha fazlası
The pT-differential production cross sections of prompt and non-prompt (produced in beauty-hadron decays) D mesons were measured by the ALICE experiment at midrapidity (|y|
The first measurements of the production of muons and electrons from heavy-flavour hadron decays in Xe–Xe collisions at √sNN = 5.44 TeV, using the ALICE detector at the LHC, are reported. The measurement of the nuclear modification factor RAA is performed as a function of transverse momentum pT in several centrality classes at forward rapidity (2.5 < y < 4) and midrapidity (|y| < 0.8) for muons and electrons from heavy-flavour hadron decays, respectively. A suppression by a factor up to about 2.5 compared to the binary-scaled pp reference is observed in central collisions at both central and f ...Daha fazlası
The first measurement of the production of pions, kaons, (anti-)protons and ϕ mesons at midrapidity in Xe-Xe collisions at sNN‾‾‾‾√=5.44 TeV is presented. Transverse momentum (pT) spectra and pT-integrated yields are extracted in several centrality intervals bridging from p-Pb to mid-central Pb-Pb collisions in terms of final-state multiplicity. The study of Xe-Xe and Pb-Pb collisions allows systems at similar charged-particle multiplicities but with different initial geometrical eccentricities to be investigated. A detailed comparison of the spectral shapes in the two systems reveals an oppos ...Daha fazlası
Systematic studies of charge-dependent two- and three-particle correlations in Pb-Pb collisions at √ sNN = 2.76 and 5.02 TeV used to probe the Chiral Magnetic Effect (CME) are presented. These measurements are performed for charged particles in the pseudorapidity (η) and transverse momentum (pT) ranges |η| < 0.8 and 0.2 < pT < 5 GeV/c. A significant charge-dependent signal that becomes more pronounced for peripheral collisions is reported for the CME-sensitive correlators γ1,1 = hcos(ϕα + ϕβ − 2Ψ2)i and γ1,−3 = hcos(ϕα − 3ϕβ + 2Ψ2)i. The results are used to estimate the contribution of backgro ...Daha fazlası
Two-particle angular correlations are measured in high-multiplicity proton-proton collisions at s√=13 TeV by the ALICE Collaboration. The yields of particle pairs at short-(Δη ∼ 0) and long-range (1.6
The production of Υ mesons in Pb-Pb collisions at a centre-of-mass energy per nucleon pair sNN‾‾‾‾√ = 5 TeV is measured with the muon spectrometer of the ALICE detector at the LHC. The yields as well as the nuclear modification factors are determined in the forward rapidity region 2.5
The event-by-event correlations between three flow amplitudes are measured for the first time in Pb-Pb collisions, using higher-order symmetric cumulants. We find that different three-harmonic correlations develop during the collective evolution of the medium when compared to correlations that exist in the initial state. These new results cannot be interpreted in terms of previous lower-order flow measurements since contributions from two-harmonic correlations are explicitly removed in the new observables. A comparison to Monte Carlo simulations provides new and independent constraints for the ...Daha fazlası
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythi ...Daha fazlası
