Strong color fields and heavy flavor production
The clustering of color sources provides a natural framework for soft
partonic interactions producing strong color fields. We study the consequences
of these color fields in the production of heavy flavor and the behavior of the
nuclear modification factor.Comment: 11 pages, 7 figures, to appear in Physical Review
Rapidity long range correlations, parton percolation and color glass condensate
The similarities between string percolation and Glasma results are
emphasized, special attention being paid to rapidity long range correlations,
ridge structure and elliptic flow. As the string density of high multiplicity
pp collisions at LHC energies has similar value as the corresponding to Au-Au
semi-central collisions at RHIC we also expect in pp collisions long rapidity
correlations and ridge structure, extended more than 8 units in rapidity.Comment: 3 pages, 3 figures, conference Quark Confinement and the hadron

Elliptic flow at RHIC and LHC in the string percolation approach
The percolation of strings gives a good description of the RHIC experimental
data on the elliptic flow, v2 and predicted a rise on the integrated v2 of the
order of 25% at LHC such as it has been experimentally obtained. We show that
the dependence of v2 on pT for RHIC and LHC energies is approximately the same
as it has been observed, for all the centralities. We show the results for
different particles and the dependence of v2 on the centralities and rapidity.
Our results are compatible with an small value of the ratio eta/s in the whole
energy range such as it was expected in the percolation framework.Comment: 20 pages, 12 figure
Evaluation of artificial feeds for shrimp (Penaeus monodon) production in brackishwater ponds
Abstract only.The experiment was conducted in fifteen 500-m2 brackishwater ponds to determine the response of Penaeus monodon juveniles fed with various artificial diets. Five treatments with three replicates each were: two commercial feeds containing 45% and 40% crude protein (treatments I and II), two experimental diets formulated to contain 35% crude protein (treatments III and IV) and control, without feeding (treatment V). Shrimp were fed twice daily at feeding rates based on shrimp consumption.
Highest mean harvest weight was attained in treatment I (23.47 g) > III (19.25 g) > II (18.86 g) > IV (11.29 g) > V (9.27 g). Statistical analysis showed that differences in growth were significant at 5% probability level. However, growth in treatments I, II and III are comparable, also growth in treatments II, III and IV. Growth in treatments I, II, III and IV was significantly different from treatment V. Highest mean survival was attained in treatment III (91.82%) > I (88.93%) > II (86.95%) > IV (83.62%) V (82.62%). Statistical analysis showed no significant differences among treatments at 5% probability level.
Projecting on a hectare basis, mean yield for each treatment was: I (628.37 kg) > II (496.35 kg) per crop in 120 days culture. Good yield was attributed to provision of formulated feeds, use of pumps in addition to tidal change for water exchange and control of predators, and pest eradication through proper pond preparation
