A turbine rotor for an Air Cycle Machine includes a hub with a multiple turbine blades which extend therefrom, each of the multiple of turbine blades defined by a set of coordinates. This is achieved through rapidly varying laser drive current, as a result of RF modulation. The indicia may take on various forms. The wall support leg and the walkway support having a gusset formed therebetween for attaching one end of one of the plurality of adjustable outriggers thereupon. The present invention also provides processes for preparing the compounds of formula I, and intermediates thereof, pharmaceutical compositions comprising those compounds, and methods of using the compounds and compositions.
