We map the gas-liquid equilibrium, which is coupled to a first-order isotropic-nematic transition. We discus how the topology of the phase diagrams changes upon varying the strengths of the isotropic and nematic interactions.<br /><br /><em>Keywords</em>: Phase diagrams; Nematic interactions; Free energy; Transitions.<br /><br />&copy; 2009 JSR Publications.
