This volume is dedicated to Professor Stefan Samko on the occasion of his seventieth birthday. The contributions display the range of his scientific interests in harmonic analysis and operator theory. Particular attention is paid to fractional integrals and derivatives, singular, hypersingular and potential operators in variable exponent spaces, pseudodifferential operators in various modern function and distribution spaces, as well as related applications, to mention but a few. Most contributions were firstly presented in two conferences at Lisbon and Aveiro, Portugal, in June-July 2011.

A child with Duchenne Muscular Dystrophy (DMD) faces a childhood and adolescence with a disability that develops gradually. This book intends to expose the problems of children with DMD. The authors discuss situations related to the disease in an attempt to provide some quality and improvement of life for those affected since DMD is a degenerative disease which affects muscle. This book offers a historical study of muscular dystrophy. It also shows some profiles of excellent clinicians and scientists that have contributed to this book with a description of muscular dystrophy from the clinical picture, to the latest techniques in genetics. Also included in the chapters are resolutions of several approaches to DMD, like scales, in order to anticipate how to manage the disease. This book relates some techniques of moderate exercise, like Yoga and water exercises, that are compliable with some advantages in mobility. The book concludes with some current trends and what can be done in the future. This book can be a good read to everyone that is interested in DMD, and also for the ones who know or provide care for those with this terrible disease.

This study contributes to the addressing of the Patent-R&D relationship from a new perspective, analyzing a crucial yet ignored question: Can more patents have a negative effect on R&D investment? Offering an extensive synthesizes of existing theoretical and empirical literature, we focus on the arguments that might sustain a negative impact of patents over R&D. The Patent system seems to have created an incentive to massive patenting with no perceivable significant(maybe even negative as our results show) impact on R&D and as for certain introduced a set of costs that may actually lower the optimal R&D investment level of firms and slow down technological progress. This book builds a strong case against the one-size-fits-all approach of IPR legislation across different technological fields and across different stages of country development, providing an intresting reading both for policy makers, as well as academic researchers. Nevertheless, its comprehensiveness and easy-to-read text also makes it suitable for the general public.
