      This article presents data on a simple, spontaneous bimanual gesture –'clap'– that was investigated in a naturalistic group of 26 chimpanzees (Pan troglodytes).
    • Immunoassays: Their history, development and current place in food science and technology

      Bonwick, Graham A.; Smith, Christopher J.; University College Chester (Wiley-Blackwell, 2004-10-20)
      This article discusses the types and variety of immunoassays, which are currently available. Immunoassays provide a powerful tool, which can be used in the analysis and quality control of food materials. For both the novice and the experienced worker the specialist terminology of a subject presents an initial barrier, which must be overcome before full understanding is achieved. In this paper an attempt is made to introduce the important terms with which the reader should be familiar and to try to set the various technologies in context. The various basic methods are described and the theoretical and practical basis of more sophisticated assays now being devised are introduced.
