The dependence of the multiplicity and the transverse momentum distribution on the number of collisions are studied for central and peripheral Au-Au collisions at SPS, RHIC and LHC energies in the framework of percolation of strings. A scaling law relating the multiplicity to the mean transverse momentum is obtained. Our results are in overall agreement with the SPS and RHIC data, obtaining a s...

We have developed new techniques to detect hadrons with the PHENIX muon spectrometers. This allows us to study the centrality dependent nuclear modification factor RCP with high pT hadrons in both forward (d direction) and backward (Au direction) rapidities, 1 < |η| < 2, in d-Au collisions atsNN = 200GeV . Preliminary results show a suppression (enhancement) of high pT hadron production in cent...

We have developed new techniques to detect hadrons with the PHENIX muon spectrometers. This allows us to study the centrality dependent nuclear modification factor RCP with high pT hadrons in both forward (d direction) and backward (Au direction) pseudo-rapidities, 1 < |η| < 2, in d-Au collisions at √ sNN = 200GeV . Preliminary results show a suppression (enhancement) of high pT hadron producti...

In recent years some of the best theoretical work on the political economy of political institutions and processes has begun surfacing outside the political science mainstream in high quality economics journals. This two-part paper surveys these contributions from a recent five-year period. In Part I, the focus is on elections, voting and information aggregation, followed by treatments of parti...

The purpose of the present study was: a) to describe the theme of verbalizations about breastfeeding in mothers' pre-term (M-PT) and full-term (M-FT) infants; b) to examine the association between these themes and mother's anxiety and depression indicators and socio-demographic characteristics and, neonatal characteristics of the infants. The sample consisted of 50 M-PT and 25 M-FT. The mothers...

Metag Angular correlations between unidentified charged trigger (t) and associated (a) particles are measured by the ALICE experiment in Pb–Pb collisions at √ sNN = 2.76 TeV for transverse momenta 0.25 < p T < 15 GeV/c, where p t T > p a T . T...

OBJECTIVE To assess the recovery effect of panaxatriol (PT) on myeloid hemopoiesis in radiation injured mice, and analyze the underlying mechanism. METHODS This study was carried out in the Animal Center of Shandong University, Jinan, China, during March to September 2006. Forty-five inbred albino mice were separated randomly into 3 groups: control group, radiation group, and radiation + PT g...

the binding energy and thermodynamic parameters of cis- platinum di ammino chlorine (cis-[pt(nh3)2cl]+) and trans- platinum di ammino chlorine (trans- [pt(nh3)2cl]+) complexes withguanine has been studied by density functional theory (dft) calculations in water. the bindingenergies (ebin) of cis- and trans-[pt(nh3)2clg]+ are calculated to be 79.38 kcal/mol and 74.98kcal/mol, respectively. the b...
