  Recently we have shown that a one-parameter scaling, $T_{coh}$, describes the
physical behavior of several heavy fermions in a region of their phase diagram.
In this paper we fully characterize this region, obtaining the uniform
susceptibility, the resistivity and the specific heat in terms of the coherence
temperature $T_{coh}$. This allows for an explicit evaluation of the Wilson and
the Kadowaki-Woods ratios in this regime. These quantities turn out to be
independent of the distance $|\delta|$ to the quantum critical point (QCP). The
theory of the one-parameter scaling corresponds to a local interacting model.
Although spatial correlations are irrelevant in this case, time fluctuations
are critically correlated as a consequence of the quantum character of the
transition.
