We focus on the phase structure of the model and study the chiral and Polyakov loop susceptibilities.4 pages, 3 figures, contribution to the proceedings of the International Workshop on Hadron Physics and Property of High Baryon Density Matter, November 22-25 2006, Xian, ChinaHigh Energy Physics - PhenomenologyNuclear Theorytext
