S. Impedovo,T. Simone,G. Dimaurogood X-ray fibre diffraction patterns, good polarised infra-red spectra and built analogue molecular models of the stick and ball kind. Their conclusions are now considered to be wrong whilst Carlstrom in 1957 using almost the same data deduced a structure which is widely held to be substantially co

Like in many other invertebrates, the nucleation and growth of mineral crystallites occur on a well defined structure of organic components, these components being more or l

M. Cobb,H. Foley,F. Petry,K. Shawr and recording system analyse scattered light for frequency and intensity. The theoretical basis of Raman vibrational spectra is photon energy exchange with the molecules vibrational states, or inelastic light scattering.

A Generalised Object-Oriented Database Modelerotized, either in smaller parts, such as mandibles, or in larger areas for the construction of the exoskeleton. Sclerotization of the insect cuticle actually results from the incorporation of diphenolic compounds into the outer parts of the integument. Due to the classical work of Karlson and his
