Abstract
It is shown that the CKMT model for the nucleon structure function
F2,
taken as the initial condition for the NLO evolution equations
in perturbative
QCD,
provides a good description of the HERA data when presented in
the form
of the logarithmic slopes of F2 versus x and Q2 (Caldwell
plot), in the
whole
available
kinematic ranges. Also the results obtained for the behavior
of the gluon
component of a nucleon are presented.
