System Size and Energy Dependence of Jet-Induced Hadron Pair Correlation Shapes in Cu+Cu and Au+Au Collisions at sqrt(s_NN) = 200 and 62.4 GeV
We present azimuthal angle correlations of intermediate transverse momentum
(1-4 GeV/c) hadrons from {dijets} in Cu+Cu and Au+Au collisions at sqrt(s_NN) =
62.4 and 200 GeV. The away-side dijet induced azimuthal correlation is
broadened, non-Gaussian, and peaked away from \Delta\phi=\pi in central and
semi-central collisions in all the systems. The broadening and peak location
are found to depend upon the number of participants in the collision, but not
on the collision energy or beam nuclei. These results are consistent with sound
or shock wave models, but pose challenges to Cherenkov gluon radiation models.Comment: 464 authors from 60 institutions, 6 pages, 3 figures, 2 tables.

Improved Measurement of Double Helicity Asymmetry in Inclusive Midrapidity pi^0 Production for Polarized p+p Collisions at sqrt(s)=200 GeV
We present an improved measurement of the double helicity asymmetry for pi^0
production in polarized proton-proton scattering at sqrt(s) = 200 GeV employing
the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The
improvements to our previous measurement come from two main factors: Inclusion
of a new data set from the 2004 RHIC run with higher beam polarizations than
the earlier run and a recalibration of the beam polarization measurements,
which resulted in reduced uncertainties and increased beam polarizations. The
results are compared to a Next to Leading Order (NLO) perturbative Quantum
Chromodynamics (pQCD) calculation with a range of polarized gluon
distributions.Comment: 389 authors, 4 pages, 2 tables, 1 figure. Submitted to Phys. Rev. D,

Serum acute phase proteins in cows with SARA (Subacute Ruminal Acidosis) suspect
The aim of this study was to evaluate the variations of Acute Phase Proteins (APPs) and other blood constituents during the onset of the sub-acute ruminal acidosis (SARA) pathological status. A total of 108 cows from 12 dairy herds were randomly selected and divided into three Groups of 36 animals each. All animals were subjected to a rumenocentesis. Group A was composed by subjects with a rumen pH>5.8, Group B was composed by subjects with a rumen pH ≤5.5≤5.8 and Group C was composed by subjects with a rumen pH<5.5. Blood samples were collected by jugular venipuncture and Haptoglobin (Hp), Serum Amyloid A (SAA), Total Proteins, Albumin and White Blood Cells (WBC) were determined. One-way ANOVA showed a statistical significance on Rumen pH, Hp, SAA. SARA seems not stimulate the APPs production from liver
J/psi Production and Nuclear Effects for d+Au and p+p Collisions at sqrt(s_NN) = 200 GeV
J/psi production in d+Au and p+p collisions at sqrt(s_NN) = 200 GeV has been
measured by the PHENIX experiment at rapidities -2.2 < y < +2.4. The cross
sections and nuclear dependence of J/\psi production versus rapidity,
transverse momentum, and centrality are obtained and compared to lower energy
p+A results and to theoretical models. The observed nuclear dependence in d+Au
collisions is found to be modest, suggesting that the absorption in the final
state is weak and the shadowing of the gluon distributions is small and
consistent with Dokshitzer-Gribov-Lipatov-Altarelli-Parisi-based
parameterizations that fit deep-inelastic scattering and Drell-Yan data at
lower energies.Comment: 331 authors, 6 pages text, 3 figures. Published in PRL. Version 2 has
minor changes required during the review and production process. Of
significant note are that (a) the original Figs. 3 and 4 are combined into a
single Fig. 3 and (b) the value of (p_T)**2 at x_F=0 changed from 3.17+/-0.33
to 3.03+/-0.40. Plain text data tables for the points plotted in figures for

Bluetongue Virus: Production And Study Of Viral Antigen For Serological Diagnosis
A soluble antigen, produced from the culture supernatant of VERO cells infected with bluetongue virus serotype 4 (BTV-S4) and concentrated by sequential ultrafiltration with membranes with cut-off values 103 and 25 × 103 NMWP, showed complete identity to standard antigens when compared by agar gel immunodiffusion (AGID) and SDS-PAGE profiles, revealing that the main protein component responsible for the AGID reaction has a molecular weight of about 60 kDa corresponding probably to the NS1 protein. © 1993.4402/03/15281286Adams, Gogolewski, Barbet, Cheevers, Identification of caprine arthritisencephalitis retrovirus proteins in immunodiffusion precipitin line (1985) J.
