Charged jet cross sections and properties in proton-proton collisions at root s=7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The differential charged jet cross sections, jet fragmentation distributions, and jet shapes are measured in pffiffi minimum bias proton-proton collisions at center-of-mass energy s 1⁄4 7 TeV using the ALICE detector at the LHC. Jets are reconstructed from charged particle momenta in the midrapidity region using the sequential recombination kT and anti-kT as well as the SISCone jet finding algorithms with several resolution parameters in the range R 1⁄4 0.2–0.6. Differential jet production cross sections measured with the three jet finders are in agreement in the transverse momentum (p ) inter ...Daha fazlası

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

KARASU UYSAL, Ayben | ALICE Collaboration

The yields of the K∗(892)0 and φ(1020) resonances are measured in Pb-Pb collisions at √sNN = 2.76 TeV through their hadronic decays using the ALICE detector. The measurements are performed in multiple centrality intervals at mid-rapidity (|y| < 0.5) in the transverse-momentum ranges 0.3 < pT < 5 GeV/c for the K∗(892)0 and 0.5 < pT < 5 GeV/c for the φ(1020). The yields of K∗(892)0 are suppressed in central Pb-Pb collisions with respect to pp and peripheral Pb-Pb collisions (perhaps due to rescattering of its decay products in the hadronic medium), while the longer-lived φ(1020) meson is not sup ...Daha fazlası

The Effect of Sr Modification and Holding Time on Si Morphology and Mechanical Properties of ETIAL 195 Alloy

ULUDAĞ, Muhammet | GEMİ, Lokman | ERYILMAZ, Muhammed Raşit | DIŞPINAR, Derya

Hypereutectic Al-Si alloys are typically used in applications where wear resistance is required. The primary factor that determines the wear properties is the morphology of Si in these types of alloys. Pouring temperature is one of the ways to control Si size and shape. On the other hand, bifilm defects that may be present in the liquid can significantly alter the morphology of Si acting as a heterogeneous nucleant. Therefore in this work, castings were made at 800 degrees C with varying holding time and the effects of bifilm on the Si morphology was studied. Bifilm content was measured by Red ...Daha fazlası

Forward-backward multiplicity correlations in pp collisions at √s = 0.9, 2.76 and 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The strength of forward-backward (FB) multiplicity correlations is measured √ s = 0.9, 2.76 and 7TeV. The measurement is performed in the central pseudorapidity region (|η| < 0.8) for the transverse momentum pT > 0.3GeV/c. Two separate pseudorapidity windows of width (δη) ranging from 0.2 to 0.8 are chosen symmetrically around η = 0. The multiplicity correlation strength (bcorr) is studied as a function of the pseudorapidity gap (ηgap) between the two windows as well as the width of these windows. The correlation strength is found to decrease with increasing ηgap and shows a non-linear increas ...Daha fazlası

Validity of and Relationship Between The Variables of Ethical Climate and Culture Patient Safety and Organizational Support

ASLAN, Şebnem | AKARÇAY, Demet

In this study, it was assumed that behavioral variables within the organization-al environment contribute to improve patient safety. For this purpose, in the initial phase, validity and reliability analysis was conducted for the scale in order to adapt to Turkish. In the second phase, the correlation between ethical climate and culture, patient safety and perceived organizational support (manager and peer support) were investi-gated. The study population involves employees (N= 300) working in four public hospi-tals in the province of Konya in Turkey. ing measures as ethical climate and cul-tur ...Daha fazlası

Centrality dependence of particle production in p–Pb collisions at √sNN= 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report measurements of the primary charged-particle pseudorapidity density and transverse momentum distributions in p-Pb collisions at sNN=5.02TeV and investigate their correlation with experimental observables sensitive to the centrality of the collision. Centrality classes are defined by using different event-activity estimators, i.e., charged-particle multiplicities measured in three different pseudorapidity regions as well as the energy measured at beam rapidity (zero degree). The procedures to determine the centrality, quantified by the number of participants (Npart) or the number of n ...Daha fazlası
