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.

Measurement of D-meson production versus multiplicity in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Abstract: The measurement of prompt D-meson production as a function of multiplic- ity in p–Pb collisions at √sNN = 5.02TeV with the ALICE detector at the LHC is re- ported. D0, D+ and D∗+ mesons are reconstructed via their hadronic decay channels in the centre-of-mass rapidity range −0.96 < ycms < 0.04 and transverse momentum interval 1 < pT < 24 GeV/c. The multiplicity dependence of D-meson production is examined by either comparing yields in p–Pb collisions in different event classes, selected based on the multiplicity of produced particles or zero-degree energy, with those in pp collisions ...Daha fazlası

Genotyping of Staphylococcus Aureus Strains Isolated From Bovine Mastitis in Turkey by Using ERIC-PCR Method.

ARSLAN, Emine | GÜLBAHÇE MUTLU, Elif

Mastitis is an intramammary infection that leads to important economic losses in dairy industry such as increasing the amount of waste milk by affecting the quality and quantity of the milk, removing cows from herd or sending them for slaughter early. Staphylococcus aureus has an important place in the fight against mastitis. In this study, it is aimed to genotyping of the 98 S. aureus isolates that were isolated from bovine mastitis by the polymerase chain reaction of enterobacterial repetitive intergenic consensus (ERIC-PCR). ERIC primers generated DNA products in sizes ranging between ~8000 ...Daha fazlası

Event-shape engineering for inclusive spectra and elliptic flow in Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on results obtained with the event-shape engineering technique applied to Pb-Pb collisions at sNN = 2.76 TeV. By selecting events in the same centrality interval, but with very different average flow, different initial-state conditions can be studied. We find the effect of the event-shape selection on the elliptic flow coefficient v2 to be almost independent of transverse momentum pT, which is as expected if this effect is attributable to fluctuations in the initial geometry of the system. Charged-hadron, -pion, -kaon, and -proton transverse momentum distributions are found to be har ...Daha fazlası

Study Gas Flow Heating In Micro-Nozzle Through Walls Instead Of Preheating

HAMEED, Amar Hasan

Previously, Preheating has been established in micro-nozzles to increase the specific impulse of thrusters and increase thrust level. However, heating may cause higher viscous losses in micro-nozzles working at low Reynolds numbers. In this work, heating is combined with gas expansion by using heated walls for convergent-divergent micro-nozzle. The flow in 2D micro-nozzle with heat generation inside the side-walls has been numerically simulated and analyzed. A wide range of low Reynolds numbers flow is tested to investigate the effect of flow parameters. A range of diverse amounts of heat flux ...Daha fazlası

Pseudorapidity and transverse-momentum distributions of charged particles in proton–proton collisions at √s = 13 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The pseudorapidity (η) and transverse-momentum (pT) distributions of charged particles produced in proton–proton collisions are measured at the centre-of-mass energy √s = 13 TeV. The pseudorapidity distribution in |η| < 1.8 is reported for inelastic events and for events with at least one charged particle in |η| < 1. The pseudorapidity density of charged particles produced in the pseudorapidity region |η| < 0.5 is 5.31 ± 0.18 and 6.46 ± 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 < pT < 20 GeV/c and |η| < ...Daha fazlası

Transforming Structures In Public Sphere: From Agora To Virtual Extension

BUDAK, Hatice

The individuals of the near past approving the law makers with a passive identity today have been trying to be the active actors by getting power from their own comments. This battle is for the public to be accepted as a value and on the behalf of suplying the public demands through a positive and integrative democracy. It also has the aim of solving the problems that prevent the individual from reaching ``a common life atmosphere{''} by graying him through minimizing or excluding him through marginalizing. With this aim, the sophisticated effort analyzes every means that will improve the rela ...Daha fazlası

Effect of Cooling Intensity and Position on Solidification in Semi-Continuous Casting of Copper

HAMEED, Amar Hasan | MOHAMMED, Ahmed Abdullah | FADHIL, Obaid

Cooling heat flux effect in both primary and secondary cooling zone has been studied in semi-continuous casting of copper billet. Sufficient cooling is essential to reduce casting defects and to get high productivity, however low rate of solidification is aimed in order to get coarser grain size and softer metal for less losses in extrusion. A three-dimensional numerical model has been developed including solidification behavior of copper through mushy zone. At steady state and constant casting speed, solid shell thickness is monitored during the reduction of cooling rate at mould region to av ...Daha fazlası

A New Approach to Early Diagnosis of Congestive Heart Failure Disease by Using Hilbert-Huang Transform

ALLAHVERDİ, Novruz | KUTLU, Yakup | ALTAN, Gökhan |

Congestive heart failure (CHF) is a degree of cardiac disease occurring as a result of the heart's inability to pump enough blood for the human body. In recent studies, coronary artery disease (CAD) is accepted as the most important cause of CHF. This study focuses on the diagnosis of both the CHF and the CAD. The Hilbert-Huang transform (HHT), which is effective on non-linear and non-stationary signals, is used to extract the features from R-R intervals obtained from the raw electrocardiogram ddata. The statistical features are extracted from instinct mode functions that are obtained applying ...Daha fazlası

Azimuthal anisotropy of charged jet production in √sNN = 2.76 TeV Pb–Pb collisions

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of the azimuthal dependence of charged jet production in central and semi- central √sNN = 2.76 TeV Pb–Pb collisions with respect to the second harmonic event plane, quantified as vch jet. Jet finding is performed employing the anti-kT algorithm with a resolution parameter R = 0.2 2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different ...Daha fazlası

Multipion Bose-Einstein correlations in pp, p-Pb, and Pb-Pb collisions at energies available at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

Three- and four-pion Bose-Einstein correlations are presented in pp, p-Pb, and Pb-Pb collisions at the LHC. We compare our measured four-pion correlations to the expectation derived from two- and three-pion measurements. Such a comparison provides a method to search for coherent pion emission. We also present mixed-charge correlations in order to demonstrate the effectiveness of several analysis procedures such as Coulomb corrections. Same-charge four-pion correlations in pp and p-Pb appear consistent with the expectations from three-pion measurements. However, the presence of non-negligible b ...Daha fazlası
