Jet Quenching in Non-Conformal Holography
We use our non-conformal holographic bottom-up model for QCD described in
1012.0116 to further study the effect of the QCD trace anomaly on the energy
loss of both light and heavy quarks in a strongly coupled plasma. We compute
the nuclear modification factor for bottom and charm quarks in an
expanding plasma with Glauber initial conditions. We find that the maximum
stopping distance of light quarks in a non-conformal plasma scales with the
energy with a temperature (and energy) dependent effective power.Comment: 4 pages, 1 figure. Proceedings for Quark Matter 201
Integration of Evidence-Based Practice in Nursing Education
Evidence based practice (EBP) has gained momentum globally, to provide effective and efficient health care.
Although EBP has evolved to a great extent over the last two decades and is accepted as an important concept by all
health care professionals, its integration in practice is still challenging. Integration of EBP in nursing profession both
in nursing practice and nursing education is an important issue. This article describes the experience of the authors
in integrating evidence based practice in nursing education in Manipal University. It focuses on the training of nurse
educators in EBP, alignment of EBP in curriculum and EBP practicum in curriculum so as to enable a nurse to identify
evidences, make appropriate clinical decisions and utilize EBP in rendering scientific and quality patient care
Polyakov Loops in Strongly-Coupled Plasmas with Gravity Duals
We study the properties of the Polyakov loop in strongly-coupled gauge
plasmas that are conjectured to be dual to five dimensional theories of gravity
coupled to a nontrivial single scalar field. We find a gravity dual that can
describe the thermodynamic properties and also the expectation value of the
Polyakov loop in the deconfined phase of quenched SU(3) QCD up to .Comment: 7 pages, 2 figures, talk presented at the International Conference on

Particle Ratios and the QCD Critical Temperature
We show how the measured particle ratios at RHIC can be used to provide
non-trivial information about the critical temperature of the QCD phase
transition. This is obtained by including the effects of highly massive
Hagedorn resonances on statistical models, which are used to describe hadronic
yields. Hagedorn states are relevant close to and have been shown to
decrease to the KSS limit and allow for quick chemical equilibrium
times in dynamical calculations of hadrons. The inclusion of Hagedorn states
creates a dependence of the thermal fits on the Hagedorn temperature, ,
which is assumed to be equal to , and leads to an overall improvement of
thermal fits. We find that for Au+Au collisions at RHIC at
GeV the best square fit measure, , occurs at MeV and
produces a chemical freeze-out temperature of 170.4 MeV and a baryon chemical
potential of 27.8 MeV.Comment: 6 pages, 2 figures, talk presented at the International Conference on
