     26Sphlow was written to model metallurgical processes involving flotation of 
    2127inclusions, such as tundishes or electron beam melting hearths. Inclusions

    143 and 4.05 for Irix and Netscape 3.01 and 4.05 for PowerPC Mac, I have heard 
    144 it doesn't work on Sandia Mac Netscape 3. My guess is that this is 
    145 because the classes are not signed.
