Palm trees, particularly coconut, arecanut and palmyrah play an important part in Indian rural life. All three produce materials for house construction, basket-making and the like, and may be tapped for juice, a popular drink either fresh or fermented. Arecanut is in widespread demand as a masticatory; but pre-eminent as a crop is the coconut, whose multifarious uses have earned for it the title “Tree of Life“. With an average annual yield of twenty nuts per tree, but the potential to produce up to two hundred, selection and breeding offer great possibilities for improvement.

In the Crucifixion scene on the remarkable bronze doors of Hildesheim Cathedral, cast for Bishop Bernward in 1015, appears a cross with a series of curious protuberances regularly disposed all round its edge. Dibelius, writing of this cross, has suggested that it represents a cross constructed of unhewn palm-trunks, conventionalized in form, and has cited, as early examples of similar crosses, the representations of crosses on some of the Monza ampullae, attributing these representations to a presumed tendency, on the part of a Palestinian craftsman, to show the Saviour's cross as if made of a wood common in Palestine. I am dealing elsewhere with the suggestion that the cross on the Hildesheim door represents palm-wood, concluding that logs of palm-trunk are not represented in that cross and that the latter is no more than one of a class fairly common, formed of conventionalized living vegetation; and I am there discussing, in considerable detail, Dibelius's further suggestion that the crosses, common in medieval times and during the early Renaissance, represented as if made of rough wood, have been derived from crosses intended to represent pieces of palm-trunk set crosswise. Although since preparing that study I have seen no reason to ascribe the origin of roughwood crosses to prototypes representing palm-trunks, either dead and as the material substance of which our Lord's cross was constructed or as living, and representing symbolically the Tree of Life, the iconographical questions–first, as to actual representations of palm-tree crosses; and, second, as to the symbolical meanings underlying such representations–suggested by Dibelius's conjectures have seemed to me to be worthy of the investigation of which I present the results below.

The carnauba, the tree of life, is a palm tree found in all regions of Brazil and has many applications, from electronics to cosmetics, with a greater emphasis on wax. The objective of this research was to obtain composites using petioles fibers from carnauba leaves and polyester resin. The powder was obtained using forage grinding and subsequent sieving, generating residues with different grain sizes. All the obtained granulometries were tested and the smaller one was chosen, due to its greater viability to obtain the composite, due to its better processability. Three mass proportions of the mixture between matrix and residues were chosen, 5%, 7.5% and 10%, since above that percentage there was a compromise in the processability and obtaining the composite studied. Mechanical, thermal and environmental characterizations were performed, which demonstrated the feasibility of the proposed composite. The carnauba powder was present in the composite as fill charge. The best formulation, 10%, was chosen to make a parabola of a solar cooker at concentration to produce cooking food. The composite can also be used in the manufacture of decorative panels for the support of televisions, as well as in the manufacture of furniture.
