  In this work we compare the nuclear modification factors in proton (deuteron)
-- nucleus collisions at CERN SPS, FNAL and RHIC energies in a wide p_T range.
In these experiments the nuclear modification factor has shown an enhancement
at p_T ~ 4 GeV/c. The height of this "Cronin peak" depends on the c.m. energy
of the collision, as it is subject to stronger shadowing at higher energies.
One of the aims of this contribution is to analyze the shadowing phenomenon at
lower (2 GeV/c < p_T < 4 GeV/c) and intermediate (4 GeV/c < p_T < 8 GeV/c)
transverse momentum. Different shadowing parameterizations are considered and
the obtained Cronin peaks are investigated at RHIC and LHC energies.
