Investigation on the behaviour of fully thermoplastic composite sandwich beams under concentrated loads

The recent development of new low cost manufacturing processes adopting thermoplastic matrices in the production of structural long fibre reinforced laminates is fostering an increasing interest towards this class of materials. The automotive sector in particular is attracted by the high energy absorbing, damage tolerance performances and manufacturing and recycling potentials of structural thermoplastic composites. In this study a number of fully thermoplastic sandwich beams have been manufactured in order to investigate flexural and shear rigidity performances as well as the indentation behavior under static concentrated loads.

Aspetti psicologici e strategie di coping nella dialisi e nel trapianto renale

Aim. Although with different results, dialysis and kidney transplantation represent two effective strategies in treating chronic uraemia. Our study compares the psychological aspects of two categories of patients: on one hand those who faced kidney transplantation and have been in dialysis, on the other hand the non complaint patients treated with these therapies. Methods. We used a test for the analysis of the personality (MMPI2) and the COPE, that tests the abilities to coping used by the patient in certain conditions that can be perceived us stressful or, in any case, as unusual. With both MMPI2 and COPE we tested 120 patients that have faced haemodialysis and 50 that have been subject t…
