Deadstar

I'm sure you all know what I mean by tidal dissipation function but it's...
Q = \frac{2 \pi E_0}{\Delta E}
and describes how much dissipation is produced. \Delta E is the energy lost over one cycle and E_0 is the peak energy stored during the cycle.
So my questions are:
How do we estimate this? I remember my lecturer saying a while ago it's not very well known for most planets. Following on from this, I read it can be used to explain the lack of resonance in Uranus's satellites but I can't get any access to the only article I could find on this. (google search only brings up further links to it's abstract)

So why are there no resonances? It clearly has to do with tidal evolution but my understanding of it is not good enough to explain something like this.
