    Systemic Circular Economy Solutions for Fiber Reinforced Composites

    Get PDF
    This open access book provides an overview of the work undertaken within the FiberEUse project, which developed solutions enhancing the profitability of composite recycling and reuse in value-added products, with a cross-sectorial approach. Glass and carbon fiber reinforced polymers, or composites, are increasingly used as structural materials in many manufacturing sectors like transport, constructions and energy due to their better lightweight and corrosion resistance compared to metals. However, composite recycling is still a challenge since no significant added value in the recycling and reprocessing of composites is demonstrated. FiberEUse developed innovative solutions and business models towards sustainable Circular Economy solutions for post-use composite-made products. Three strategies are presented, namely mechanical recycling of short fibers, thermal recycling of long fibers and modular car parts design for sustainable disassembly and remanufacturing. The validation of the FiberEUse approach within eight industrial demonstrators shows the potentials towards new Circular Economy value-chains for composite materials

    Drug development progress in duchenne muscular dystrophy

    Get PDF
    Duchenne muscular dystrophy (DMD) is a severe, progressive, and incurable X-linked disorder caused by mutations in the dystrophin gene. Patients with DMD have an absence of functional dystrophin protein, which results in chronic damage of muscle fibers during contraction, thus leading to deterioration of muscle quality and loss of muscle mass over time. Although there is currently no cure for DMD, improvements in treatment care and management could delay disease progression and improve quality of life, thereby prolonging life expectancy for these patients. Furthermore, active research efforts are ongoing to develop therapeutic strategies that target dystrophin deficiency, such as gene replacement therapies, exon skipping, and readthrough therapy, as well as strategies that target secondary pathology of DMD, such as novel anti-inflammatory compounds, myostatin inhibitors, and cardioprotective compounds. Furthermore, longitudinal modeling approaches have been used to characterize the progression of MRI and functional endpoints for predictive purposes to inform Go/No Go decisions in drug development. This review showcases approved drugs or drug candidates along their development paths and also provides information on primary endpoints and enrollment size of Ph2/3 and Ph3 trials in the DMD space

    Representations of the Cuban Revolution in the American Gaze: The Case of African-American Activists

    Get PDF
    For more than six decades, the Cuban Revolution has been the object of representation by foreign authors―historians, anthropologists, sociologists, political scientists, and also poets and writers. After the triumph of Fidel Castro on January 1, 1959, his revolution captured the imagination of U.S. intellectuals and activists. Many of them traveled to Cuba to become witnesses of the radical transformations that were taking place there. In my dissertation, I suggest that visiting Cuba was important for them to authenticate their views. Writing from Castro’s Cuba lent legitimacy to their narratives, with which they hoped to influence U.S. public opinion.My focus is on African-American citizens who sought refuge in communist Cuba. Some wrote about their experiences while still living on the Island and others after returning home. Some portrayed the Cuban Revolution as a utopian experiment. Others saw it as a dystopian system that betrayed the emancipation efforts of Cubans. I show the ways in which, in the context of the Cold War, the revolution was understood by foreigners as an exceptional alternative to representative democracy and capitalism. I discuss how the American gaze of these travelers encompassed an effort to write from the perspective of Cubans. I also consider that, ultimately, their narratives aimed to interpret Cuban reality for the American public in service of their own political agendas. My research has found that the same social issues―including racism―roiling the U.S. were, when displaced to Cuba, perceived in strikingly different ways by these writers than when they lived in the United States. I group these narratives in two clusters: those by travelers who adapted to the Cuban Revolution and those who resisted it. In the first group, the American gaze from the outside was adjusted over time. In the second, it undergoes an ideological inversion where the authors are alienated as revolutionary allies. My results invite new lines of multidisciplinary analysis in aspects not sufficiently explored by the fields of African American and Latin American studies

    New Trends in 3D Printing

    A quarter century period of the 3D printing technology development affords ground for speaking about new realities or the formation of a new technological system of digital manufacture and partnership. The up-to-date 3D printing is at the top of its own overrated expectations. So the development of scalable, high-speed methods of the material 3D printing aimed to increase the productivity and operating volume of the 3D printing machines requires new original decisions. It is necessary to study the 3D printing applicability for manufacturing of the materials with multilevel hierarchical functionality on nano-, micro- and meso-scales that can find applications for medical, aerospace and/or automotive industries. Some of the above-mentioned problems and new trends are considered in this book
