Study of cosmic ray events with high muon multiplicity using the ALICE detector at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

ALICE is one of four large experiments at the CERN Large Hadron Collider near Geneva, specially designed to study particle production in ultra-relativistic heavy-ion colli- sions. Located 52 meters underground with 28 meters of overburden rock, it has also been used to detect muons produced by cosmic ray interactions in the upper atmosphere. In this paper, we present the multiplicity distribution of these atmospheric muons and its compari- son with Monte Carlo simulations. This analysis exploits the large size and excellent tracking capability of the ALICE Time Projection Chamber. A special em ...Daha fazlası

There is a continuous search for the safest abdominal entry technique, considering the recent progressions in laparoscopic surgery. In this study, we wanted to share a novel technique that we have identified for safe laparoscopic entry in obese patients. A total of 2936 laparoscopic operations were performed in general surgery, urology, and gynecology departments of Mevlana University from 2003 to 2013. The number of patients with a body mass index (BMI) ≥30 was 764. We have identified a new technique for a safer first entry in these patients. Direct open surgery, insertion techniques in which ...Daha fazlası

ASLAN, Şebnem | AKARÇAY, Demet

This correlational study assessed the effect of information technology within the health sector on knowledge quality. In this context, the mediator roles of explicit and tacit knowledge management orientation in the relationship between information technology and knowledge quality were investigated. Healthcare employees of four public hospitals in Konya that is a province of Turkey were administrated knowledge quality scale of wood (2005), explicit and tacit knowledge management orientation scale and information technology support scale, which were developed by Choi and Lee (2003) and cited fr ...Daha fazlası

Power Aware Routing Protocols in Wireless Sensor Network

ALSULTAN, Mohammed | ÖZTOPRAK, Kasım | HASSANPOUR, Reza

Wireless Sensor Networks (WSNs) have gained importance with a rapid growth in their applications during the past decades. There has also been a rise in the need for energy-efficient and scalable routing along with the data aggregation protocols for the large scale deployments of sensor networks. The traditional routing algorithms suffer from drawbacks such as the presence of one hop long distance data transmissions, very large or very small clusters within a network at the same moment, over-accumulated energy consumption within the cluster-heads (CHs) etc. The lifetime of WSNs is also decrease ...Daha fazlası

Nursing Care Satisfaction of Surgery Patients

SAYIN, Yazile | ÖNER CENGİZ, Hatice | AYOĞLU, Tuluha

Objectives: To provide guidance on improving the quality of care by evaluating the patient satisfaction in surgery clinics. Methods: The descriptive study was conducted on 402 surgical patients. Data were collected by means of the survey (based literature) and the Newcastle Nursing Care Satisfaction Scale, which was found to be valid and reliable in its Turkish version by Akin and Erdogan in 2007.Results: In this study, the nursing care satisfaction of females was higher than that of males and that of employed persons was higher than that among unemployed persons. Nursing care satisfaction sco ...Daha fazlası

Centrality dependence of the nuclear modification factor of charged pions, kaons, and protons in Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Transverse momentum (pT) spectra of pions, kaons, and protons up to pT = 20 GeV/c have been measured in Pb-Pb collisions at √sNN = 2.76 TeV using the ALICE detector for six different centrality classes covering 0%–80%. The proton-to-pion and the kaon-to-pion ratios both show a distinct peak at pT ≈ 3 GeV/c in central Pb-Pbcollisionsthatdecreasesformoreperipheralcollisions.ForpT >10GeV/c,then uclear modification factor is found to be the same for all three particle species in each centrality interval within systematic uncertainties of 10%–20%. This suggests there is no direct interplay between ...Daha fazlası

Particle identification in ALICE: a Bayesian approach

KARASU UYSAL, Ayben | ALICE Collaboration

We present a Bayesian approach to particle identification (PID) within the ALICE experiment. The aim is to more effectively combine the particle identification capabilities of its various detectors. After a brief explanation of the adopted methodology and formalism, the performance of the Bayesian PID ap- proach for charged pions, kaons and protons in the central barrel of ALICE is studied. PID is performed via measurements of specific energy loss (dE/dx) and time of flight. PID efficiencies and misidentifica- tion probabilities are extracted and compared with Monte Carlo simulations using hig ...Daha fazlası

Production of light nuclei and anti-nuclei in pp and Pb-Pb collisions at energies available at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

The production of (anti-)deuteron and (anti-)3He nuclei in Pb-Pb collisions at √sNN = 2.76 TeV has been studied using the ALICE detector at the LHC. The spectra exhibit a significant hardening with increasing centrality. Combined blast-wave fits of several particles support the interpretation that this behavior is caused by an increase of radial flow. The integrated particle yields are discussed in the context of coalescence and thermal-statistical model expectations. The particle ratios, 3 He /d and 3 He /p, in Pb-Pb collisions are found to be in agreement with a common chemical freeze-out te ...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

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
