Deformations of Spacetime Symmetries
This monograph provides an introduction to deformations of Poincaré symmetries focusing on models with a Lie group momentum space and associated non-commutative space-times. The emphasis is put on the emergence of such structures from quantum gravity, their mathematical features described in terms of Hopf algebras and applications to particle kinematics and field theory. Part I of this work focuses on the link between gravity and deformed symmetries in the case of 2+1 and 3+1 space-time dimensions. Part II is devoted to the description of classical particles with group valued momenta, their phase spaces and kinematics. The last part of these notes provides an introduction to the basic features of classical and quantum field theory on κ-Minkowski space-time, the prototypical example of non-commutative space-time exhibiting deformed Poincaré symmetry. The text, being the first providing a detailed overview of these topics, is primarily intended for researchers and graduate students interested in non-commutative field theories and quantum gravity phenomenology.
Advances in Natural Hazards and Volcanic Risks: Shaping a Sustainable Future
This book comprises the selected proceedings of the 3rd International Workshop on Natural Hazards (NATHAZ’22), Angra do Heroísmo, Terceira Island, Azores, 2022. The book interests all researchers and practitioners in Earth Sciences, Volcanic Risks, Natural Hazards, Geoethics, Environmental Sciences and Engineering. Terceira is a volcanic island with volcanic systems with caldera (Cinco Picos, Guilherme Moniz, Santa Bárbara and Pico Alto central volcanoes) and an active fissural zone defined by various alignments of small volcanic cones, lava domes and fault zones. The agricultural landscape, the natural and forest reserve, as well as the natural pools make the island a unique place to vi...
The Promise of Francis
With more than four decades of firsthand experience reporting from Vatican City, David Willey explores the religious and personal background of Pope Francis and his ability to fulfill the promises of reform made during the first two years of his papacy. Sex crimes and cover-ups, financial scandal, declining membership, and the unprecedented resignation of its chief executive, Pope Benedict XVI. These were the ingredients of a twenty-first century crisis in the Vatican—a crisis that might have anticipated the election of a steadily conservative pope, a career bureaucrat, and an insider. An operator. Instead they chose Francis. Using his unparalleled access and knowledge of the inner working...
Chemical Sciences in the 20th Century
Chemistry in the last century was characterized by spectacular growth and advances, stimulated by revolutionary theories and experimental breakthroughs. Yet, despite this rapid development, the history of this scientific discipline has achieved only recently the status necessary to understand the effects of chemistry on the scientific and technological culture of the modern world. This book addresses the bridging of boundaries between chemistry and the other "classical" disciplines of science, physics and biology as well as the connections of chemistry to mathematics and technology. Chemical research is represented as an interconnected patchwork of scientific specialties, and this is shown b...
Electromagnetics for High-Speed Analog and Digital Communication Circuits
Modern communications technology demands smaller, faster and more efficient circuits. This book reviews the fundamentals of electromagnetism in passive and active circuit elements, highlighting various effects and potential problems in designing a new circuit. The author begins with a review of the basics - the origin of resistance, capacitance, and inductance - then progresses to more advanced topics such as passive device design and layout, resonant circuits, impedance matching, high-speed switching circuits, and parasitic coupling and isolation techniques. Using examples and applications in RF and microwave systems, the author describes transmission lines, transformers, and distributed circuits. State-of-the-art developments in Si based broadband analog, RF, microwave, and mm-wave circuits are reviewed. With up-to-date results, techniques, practical examples, illustrations and worked examples, this book will be valuable to advanced undergraduate and graduate students of electrical engineering, and practitioners in the IC design industry. Further resources for this title are available at www.cambridge.org/9780521853507.

Biografie Luisa Piccarreta, Dienerin Gottes
Info: goettlicherwille.org - Aufgrund einer eindringlichen Aufforderung des nunmehr emeritierten Erzbischofs von Trani, Msgr. Giuseppe Carata, fühlte ich mich veranlaßt, die Zeugnisse über Luisa Piccarreta schriftlich niederzulegen. Es sind dies gesammelte mündliche Zeugnisse seitens meiner Familie und anderer Personen, die die Dienerin Gottes persönlich gekannt haben. In einigen Episoden bin ich direkt beteiligt. In meiner Jugend hatte ich ständigen und direkten Kontakt mit der Dienerin Gottes durch meine Tante Rosaria Bucci, die ungefähr vierzig Jahre lang Tag und Nacht der Dienerin Gottes zur Seite stand.. Pater Bernadino Bucci O.F.M
