masses. Whilst overlooking many of the technical aspects of this procedure at this point, it is a remarkable achievement that the formalism is in more than solid agreement with nature. Aside from determining particle spectra, one of the current main problems is to measure matrix elements of operators in the non-perturbative region. These are important in, for instance, understanding the structure of nucleons if one focuses on the operators relating to deep inelastic scattering. These were introduced originally in [@1] which subsequently produced an intense industry to determine the operator anomalous dimensions for arbitrary moment to eventually three loops in the ${\overline{\mbox{MS}}}$ renormalization scheme, [@2; @3; @4; @5; @6; @7]. Indeed there has been a large degree of progress in the area of measuring matrix elements of quark bilinear currents and operators and the associated renormalization constants by the QCDSF collaboration, [@8; @9; @10; @11; @12; @13; @14], and others [@15; @16; @17; @18; @19; @20; @21; @22; @23; @24]. However, in order to make reliable measurements and hence accurate predictions one has to overcome various theoretical difficulties. Aside from those relating specifically to the lattice, there is the problem of ensuring the results match on to what would be
