Production of K∗(892)0 and φ(1020) in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of K∗(892)0 and φ(1020) mesons has been measured in p–Pb collisions at √sNN = 5.02 TeV. K∗0 and φ are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range −0.5 < y < 0. The transverse momentum spectra, mea- sured as a function of the multiplicity, have a pT range from 0 to 15 GeV/c for K∗0 and from 0.3 to 21 GeV/c for φ. Inte- grated yields, mean transverse momenta and particle ratios are reported and compared with results in pp collisions at √s = 7 TeV and Pb–Pb collisions at √sNN = 2.76 TeV. In Pb–Pb and p–Pb collisions, K∗0 and φ pr ...Daha fazlası

AZAK, Hacer | KURBANOĞLU, Sevinç | YILDIZ, Hüseyin Bekir | ÖZKAN, Sibel Ayşıl

The synthesis of derivatives of dithionepyrrole is a hot subject that has been studied extensively. In this study, a novel approach for constructing different glucose biosensors using conducting polymers of 4-(4H-dithyinol[3,2-b:2′,3′-d]pyroll-4-yl)aniline and 4-(4H-dithyinol[3,2-b:2′,3′-d]pyroll-4-yl)-[1,1′-biphenyl]-4-amine is proposed. After the synthesis and characterizations of the dithionepyrrole type monomers, they were used in glucose biosensing applications. The surface of gold electrode was modified with mercaptoethane sulfonic acid and p-aminothiophenol functionalized gold nanoparti ...Daha fazlası

Effects of helicobacter pylori infections on ghrelin and leptin levels

KEFELİ, Ayşe | YENİOVA, Ahmet Özgür | BAŞYİĞİT, Sebahat | UZMAN, Metin | ASILTÜRK, Zeliha | TANRIKULU, Yusuf | NAZLIGÜL, Yaşar

Introduction: Helicobacter pylori (H. pylori) infection is common throughout the world. Ghrelin and leptin peptides play a crucial role in the homeostasis of the human body. Previously, some studies showed that H. pylori colonization had been associated with circulating leptin and ghrelin levels, but the certain relationship is still uncertain. The goal of this study is to determine the effects of H. pylori infection on serum ghrelin and leptin levels and how these relates to body weight changes before and after H. pylori eradication. Materials and methods: This study prospectively enrolled 12 ...Daha fazlası

Higher harmonic flow coefficients of identified hadrons in Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The elliptic, triangular, quadrangular and pentagonal anisotropic flow coeffi- cients for π±, K± and p+p in Pb-Pb collisions at √sNN = 2.76 TeV were measured with the ALICE detector at the Large Hadron Collider. The results were obtained with the Scalar Product method, correlating the identified hadrons with reference particles from a different pseudorapidity region. Effects not related to the common event symmetry planes (non-flow) were estimated using correlations in pp collisions and were subtracted from the measure- ment. The obtained flow coefficients exhibit a clear mass ordering for tra ...Daha fazlası

Quality function deployment: An application on determining the quality factors in higher education

GÜNDÜZ, Mehmet Akif

Quality Function Deployment (QFD) is a method developed in the 1970’s in Japan by Dr. Yoji Akao and with later contributions of Shigeru Mizuno. QFD is adopted all over the world following a number of successful applications in Japan and has been applied very widely until today. This term has been translated to English as "Quality Function Deployment" from original Japanese name "Ten Kai Hin Shits Ki No". The most basic purpose of QFD is to design the functions which product performs according to the needs and requirements of customers. The aim of this study is to apply QFD in a university in T ...Daha fazlası

3ΛH and 3Λ¯ production in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of the hypertriton nuclei 3ΛH and 3Λ¯ has been measured for the first time in Pb–Pb collisions at √sNN = 2.76 TeV with the ALICE experiment at LHC. The pT-integrated 3 !H yield in one unity of rapidity, dN/dy × B.R. ! 3 !H→3He,π−" = (3.86 ± 0.77(stat.) ± 0.68(syst.)) × 10−5 in the 0–10% most central collisions, is consistent with the predictions from a statistical thermal model using the same temperature as for the light hadrons. The coalescence parameter B3 shows a dependence on the transverse momentum, similar to the B2 of deuterons and the B3 of 3He nuclei. The ratio of yield ...Daha fazlası

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

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
