    Hadronization via Coalescence

    Full text link
    We review the quark coalescence model for hadronization in relativistic heavy ion collisions and show how it can explain the observed large baryon to meson ratio at intermediate transverse momentum and scaling of the elliptic flows of identified hadrons. We also show its predictions on higher-order anisotropic flows and discuss how quark coalescence applied to open- and hidden-charm mesons can give insight to charm quark interactions in the quark-gluon plasma and J/ΨJ/\Psi production in heavy ion collisions.Comment: 6 pages, 4 figures, Proceedings of 20th Winter Workshop on Nuclear Dynamics, Trelawny Beach, Jamaica, March 15--20, 200

    Effect of resonance decays on hadron elliptic flows

    Get PDF
    The influence of resonance decays on the elliptic flows of stable hadrons is studied in the quark coalescence model. Although difference between the elliptic flow of pions from resonance decays, except the rho meson, and that of directly produced pions is appreciable, those for other stable hadrons are small. Since there are more pions from the decays of rho mesons than from other resonances, including resonance decays can only account partially the deviation of final pion elliptic flow from the observed scaling of hadron elliptic flows, i.e., the hadron elliptic flow per quark is the same at same transverse momentum per quark. The remaining deviation can be explained by including the effect due to the quark momentum distribution inside hadrons.Comment: 13 pages and 5 figures, version pubblished in PRC, updated references and figure

    Multiliteracies: Bringing Multimodality into Schools

    Today’s technological advancements provide cause for literacy educators to think about literacy as many literacies or multiliteracies (Cimbricz & Rath, 2015). This analytical review explores the construct of multiliteracy in hopes of discovering how to help students become multiliterate and learn the many literacies important to today’s world. This review examines four case studies that speak to the actual impact multiliteracies has on student and teacher learning. My analysis suggests that in some cases, student engagement improved when the teaching and learning of multiliteracies were used in schools. Furthermore, the integration of multiple modes of meaning making seemed to better meet the needs of all students in the classroom. Unfortunately, mot much is known about multiliteracies, and its actual impact on student and teacher learning remains relatively unknown

    On the Path Integral Representation for Spin Systems

    Full text link
    We propose a classical constrained Hamiltonian theory for the spin. After the Dirac treatment we show that due to the existence of second class constraints the Dirac brackets of the proposed theory represent the commutation relations for the spin. We show that the corresponding partition function, obtained via the Fadeev-Senjanovic procedure, coincides with the one obtained using coherent states. We also evaluate this partition function for the case of a single spin in a magnetic field.Comment: To be published in J.Phys. A: Math. and Gen. Latex file, 12 page

    Study to establish cost projections for production of Redox chemicals

    Get PDF
    A cost study of four proposed manufacturing processes for redox chemicals for the NASA REDOX Energy Storage System yielded favorable selling prices in the range 0.99to0.99 to 1.91/kg of chromic chloride, anhydrous basis, including ferrous chloride. The prices corresponded to specific energy storage costs from under 9to9 to 17/kWh. A refined and expanded cost analysis of the most favored process yielded a price estimate corresponding to a storage cost of $11/kWh. The findings supported the potential economic viability of the NASA REDOX system
