η−η′\eta - \eta' in a hot and dense medium

The behavior of $\eta$ and $\eta'$ in hot strange quark matter in weak equilibrium with temperature, is investigated within the SU(3) Nambu-Jona-Lasinio [NJL] model. Possible manifestations of restoration of symmetries, by temperature or density, in the behavior of $\eta$ and $\eta'$ are discussed. The role played by the combined effect of temperature and density in the nature of the phase transition and meson behavior is also analyzed.Comment: 15 pages, 5 figures.

Consumer Demand for Ahi Poke (Raw Tuna Salad) in Hawaii

Ahi poke (raw tuna salad) has significant role in Hawaii culture and economy. A consumer survey in Hawaii was used to examine consumers’ purchasing intentions of ahi poke. A censored analysis was conducted to analyze the demand and tie with various consumer characteristics. Results show that many consumer eat ahi poke frequently and different consumer profiles will lead to large differences in their demand. Information obtained in study may help producers and retailers to better target their marketing strategies and increase sales.Ahi Poke, Demand, Hawaii, Tobit, Agribusiness, Agricultural and Food Policy, Consumer/Household Economics, Demand and Price Analysis, Marketing, Q13, D12,

The QCD Critical End Point in the Context of the Polyakov--Nambu--Jona-Lasinio Model

We investigate the phase diagram of the so-called Polyakov--Nambu--Jona-Lasinio model at finite temperature and nonzero chemical potential with three quark flavors. Chiral and deconfinement phase transitions are discussed, and the relevant order-like parameters are analyzed. A special attention is payed to the critical end point (CEP): the influence of the strangeness on the location of the CEP is studied; also the strength of the flavor-mixing interaction alters the CEP location, once when it becomes weaker the CEP moves to low temperatures and can even disappear.Comment: Prepared for Strangeness in Quark Matter 2011, Sept. 18--24, Cracow, Polan
