  Abstract:
In this paper the analysis of certain logarithmic expansions, which developed for precision studies of the evolution of the QCD parton distributions (pdf) at the Large Hadron Collider, is used. The xF3 data of the CCFR collaboration is used to parameterize the non-singlet parton distributions in this order. In the �tting procedure, Bernstein polynomial method is employed. The results of valence quark distributions in the NLO are compered with exact and truncated solutions for non-singlet case.
