Target Mass Corrections for Polarized Structure Functions and New Sum Rules

The target mass corrections are calculated for all structure functions of neutral and charged current deep inelastic scattering in lowest order in the coupling constant. Representations of the correction to the twist--2 and twist--3 contributions are derived both in Mellin-$n$ and $x$-space. The impact of the target mass corrections on the general relations between the twist--2 and twist--3 parts of the structure functions is studied and three new relations between the twist--3 contributions are derived.Comment: 34 pages LATEX, 1 style fil

Acute spinal rigidity

In each section of this chapter, relevant case histories from the literature illustrating structural, inflammatory or paraneoplastic causes of spinal rigidity are discussed to highlight the presenting and diagnostic features. Such cases are rare, and the importance of imaging cannot be overemphasised in cases of segmental rigidity where a spinal origin is supsected. Modern imaging techniques permit detailed anatomical examination of the spinal cord, making such diagnoses much simpler than in the past.P.D. Thompso
