Query: From confining fields back to power corrections   We overview the issue of the power corrections to the parton model, mostly
within the context of QCD sum rules. There are a few sources of the power
corrections responsible for various qualitative effects. The basic idea that
the power corrections are related to confining fields seems to be realized in
case of $1/Q^2$ corrections which are dual to high orders of perturbation
theory. The evidence comes from lattice studies of the confinement which
allowed to identify the confining field configurations as monopoles and
vortices. We comment also on the role of the condensate of dimension two,
$<(A_{\mu}^a)^2>_{min}$.
