An experimental study on the transverse vibration of a power transmission belt
No full textIn this paper an experimental study on the transversal vibrations of a rubber flat belt is presented. The aim is to evaluate the influence of the axial velocity on system vibrations and to study the nonlinear system behaviour in resonance conditions. Since the transversal vibration of a non-still surface cannot be measured through classical testing tools such as accelerometers, strain-gauges, etc., the measurements are performed using a laser-Doppler vibrometer. The axial velocity is identified by a simple axially moving string model. Nonlinear vibrations are observed and qualitatively compared with those of a hardening Duffing oscillator. The experimental results are compared to, and explained through, the theoretical and numerical predictions presented in the literature
Introduction. Climate Change Integration in the Multilevel Governance of Italy and Austria
No full textWhat Is Italian Antispeciesism? An Overview of Recent Tendencies in Animal Advocacy
No full textThis chapter offers an overview of the different agents currently operating in Italy as part of the animal liberation movement. It analyses the impact on this social reality by books and essays published or translated in Italian in the last 20 years in the field of Animal Ethics. From the reception of Peter Singer and Tom Regan’s ideas mediated by the work of Paola Cavalieri, Italian philosophers have shaped the narratives and the rhetoric of animal advocates and liberationists. On the other side, activists’ debates on the best strategies to adopt involved intellectuals and enriched their production on Animal Liberation. Groups with an intersectional approach have paid particular attention to theoretical implications and political consequences of their acts, developing radical, non-anthropocentric forms of antispeciesism
Influence of water activity and anti-fungal compounds on development and competiveness of F. verticillioides
No full textA study was undertaken to investigate the role of water activity (aw) and fungicides on the competitiveness of two Fusarium verticillioides strains against other spoilage fungi commonly present in maize (F. proliferatum, Aspergillus niger, A. flavus, A. ochraceus and Penicillium verrucosum). Fungal strains were inoculated on artificial media containing maize flour. The effect of three aw levels (0.99, 0.98 and 0.95) and 3 fungicides (Tebuconazole, Procloraz and Prothioconazole) on fungal interactions, the Index of Dominance (ID) of isolates and fumonisin B1+B2 (FBs) production were determined. The two strains of F. verticillioides showed similar behaviour in conditions where water was freely available (0.99 aw); at 0.98 and 0.95 aw both F. verticilliodes strains had the lowest total ID scores (8-6 and 10-12, respectively). They showed the same ability to compete against other fungi having the highest ID scores against P. verrucosum and A. ochraceus and the lowest against A. niger and A. flavus. Interestingly, 0.95 aw was the most conducive condition for fumonisin production with significant differences respect to 0.98 and 0.99 aw. In co-inoculation experiment, only FBs production obtained with P. verrucosum resulted significantly higher from those obtained in the presence of the other fungi. The use of fungicides reduced both F. verticilliodes strains Index of Dominancy (ID). In particular, a significant reduction in F. verticilloides strain growth was observed when combining water stress x fungicide treatments. This information could be useful for a better understanding of the colonisation patterns of F. verticillioides in relation to other mycobiota and to both environmental and chemical stresses, also in future climate change scenarios

No full textIn this paper the effect of a pulley eccentricity on power transmission belt is experimentally investigated. The evaluation of the nonlinear behaviour of the belt, in presence of large amplitude of vibration due to special resonance conditions, is the goal of the present work. Transversal vibrations of moving surfaces cannot be measured through classical transducers such as accelerometers; therefore in this case Laser displacement transducers are used. An hardening nonlinear behaviour of the system is observed, i.e. the stiffness of the systems grows with the amplitude of vibration. The experimental amplitude-frequency response curve is compared with that of a hardening Duffing oscillator representing the nonlinear vibration when the first mode is directly excited. A parametric resonance phenomenon of subarmonic kind is observed. This is due to the tension fluctuation. The experimental results are explained and compared with those present in literature
Stresses in Universal Ceramic Heads for Total Hip Replacement: Effect of Stem Elastic Modulus and Frictional Coefficient
No full textIslet cell transplantation
No full textIslet cell transplantation is an attractive alternative therapy to conventional insulin treatment or vascularized whole pancreas transplantation for type 1 diabetic patients. It represents a successful example of somatic cell therapy in humans based on complex procedures for islet isolation from whole pancreas. The islets, that are only 1% of the total pancreas tissue, are isolated by two steps method starting with collagenase digestion that operates a rapid dissociation of the stromal component of the gland, while preserving islet anatomical integrity. After digestion, islets are then separated from exocrine tissue by centrifugation in density gradients. Transplantation consists of a simple injection of few milliliter-purified tissue in the portal vein through a percutaneous trans- hepatic approach performed in local anesthesia. Several studies have now demonstrated that islet transplant can replace pancreatic endocrine function without major side effects and with liver viability preservation in selected patients affected by longterm type 1 diabetes. It can restore endogenous insulin secretion, achieve insulin independence in more than 80% of patients, and recover the metabolism of glucose, protein and lipids. Improved control of glycated HbAlc, reduced risk of recurrent hypoglycemia and of diabetic complications are also seen as important benefits of islet cell transplantation, irrespective of the status of insulin independence. Many protocols are now on going for reduction of immunosuppression therapy in recipients, induction of tolerance, and prolongation of graft function
