The present invention is an improved business method that marries the real estate listing process with property improvement services to enable the property seller to sell an improved property without bearing the costs of the improvement. Immediately before time T2, the power of light L2 is slightly lower than the absorption saturation threshold. The graphical design tool generates modules using a hardware description language to represent the primary logic component of the circuit. The plurality of conduits may also include a second conduit fluidly coupled to the first conduit and the compressor, and configured to flow therethrough a second process fluid stream of the plurality of process fluid streams.
