    Notes: Abstract Somatic embryogenesis was achieved in callus cultures dervied from 40-day-old semimature zygotic embryos of Dalbergia sissoo on semi-solid Murashige and Skoog (MS) salts and vitamins supplemented with 0.46–1.16 µM kinetin, 6.78–9.04 µM 2,4-dichlorophenoxy acetic acid (2,4-D) and 30 g/l sucrose. Somatic embryos proliferated rapidly by secondary somatic embryogenesis after transfer to half-strength basal MS medium supplemented with 0.46–1.16 µM kinetin and 6.78– 9.04 µM 2,4-D with 2% (w/v) sucrose. The light-green somatic embryos germinated on half-strength MS salts and vitamins supplemented with 0.5 mg/l abscisic acid and 2% (w/v) sucrose. The developmental stages of somatic embryogenesis were studied by light and scanning electron microscopy.

    The invariant manifold of beam deformations (1993)

    Notes: Abstract The subcentre invariant manifold of elasticity in a thin rod may be used to give a rigorous and appealing approach to deriving one-dimensional beam theories. Here I investigate the analytically simple case of the deformations of a perfectly uniform circular rod. Many, traditionally separate, conventional approximations are derived from within this one approach. Furthermore, I show that beam theories are convergent, at least for the circular rod, and obtain an accurate estimate of the limit of their validity. The approximate evolution equations derived by this invariant manifold approach are complete with appropriate initial conditions, forcing and, in at least one case, boundary conditions.
