Introduction The relationship between intellectual disability (ID) and hand motor coordination and speed-accuracy, as well as the effect of aging on fine motor performance in patients with ID, has been previously investigated. However, only a few data are available on the impact of the nonpharmacological interventions in adult patients with long-term hand motor deficit. Methods Fifty adults with mild ID were enrolled. A group of thirty patients underwent a two-month intensive ergotherapic treatment that included hand motor rehabilitation and visual-perceptual treatment (group A); twenty patients performing conventional motor rehabilitation alone (group B) served as a control group. Data on attention, perceptual abilities, hand dexterity, and functional independence were collected by a blind operator, both at entry and at the end of the study. Results After the interventions, group A showed significantly better performance than group B in all measures related to hand movement from both sides and to independence in activities of daily living. Discussion Multimodal integrated interventions targeting visual-perceptual abilities and motor skills are an effective neurorehabilitative approach in adult patients with mild ID. Motor learning and memory-mediated mechanisms of neural plasticity might underlie the observed recovery, suggesting the presence of plastic adaptive changes even in the adult brain with ID.

This paper summarises a series of small scale tests carried out to evaluate and model the postcrash fire integrity of composite aircraft fuselage structures. The US Federal Aviation Administration regulations for the penetration of an external fuel fire into an aircraft cabin after crash require a burn-through period of 4 min (FAA 1 25?856 Appendix F, Part VII). Different candidate structures for the next generation of composite aircraft fuselage, provided by EADS, were investigated, including CFRP monolithic laminate and a folded core CFRP sandwich. Those materials were subjected to constant heat flux from a propane gas burner, while being held under compressive load in a small, specially designed compression test rig with antibuckling guides. The sample time to failure was measured, along with the temperatures at various points through the thickness. Modelling the thermal and structural behaviour under load required the use of a modified version of the Henderson equation, which describes heat transfer through composites under ablative fire conditions. This has been incorporated into the Com_Fire software model. Kinetic parameters for the resin decomposition reaction were determined from thermogravimetric data and other thermal parameters, conductivity and diffusivity, were measured experimentally. The paper will examine measured and modelled behaviour of the CFRP monolithic laminate.

Different candidate structures for the next generation of composite aircraft fuselage, provided by Airbus, were investigated, including CFRP monolithic laminate and a folded-core CFRP sandwich. Those materials were subjected to constant heat flux from a propane gas burner, while being held under compressive load in a small, specially designed compression test rig with anti-buckling guides. The propane burner was calibrated to produce a constant heat flux up to 182 kW/m 2 . The sample time-to-failure was measured, along with the temperatures at various points through the thickness.Modelling the thermal and structural behaviour under load required the use of a modified version of the Henderson Equation, which describes heat transfer through composites under ablative fire conditions. This has been incorporated into the Com-Fire software model. Kinetic parameters for the resin decomposition reaction were determined from thermo-gravimetric data and other thermal parameters, conductivity and diffusivity were measured experimentally. The paper will compare the behaviour of single and double-skinned structures and will examine measured and modelled behaviour.
