OK, I put the latest versions here http://djk.se/The%20adiabatic%20heat%20gradient%20for%20solids%20and%20the%20heat%20conduction%20through%20the%20earth%20crust.pdf
Tell me what you think. The correspondence was remarkably high, especially since I only have one figures precisions in two of the constants used.
