The achieved accuracy allows the measurement of the running coupling and the study of non-perturbative effects, in particular the test of universality of power corrections in a new experimental regime.5 pages, 1 figure, talk given at X International Workshop on Deep Inelastic Scattering (DIS2002), Krakov, PolandHigh Energy Physics - Phenomenologytext
