This fascinating selection of photographs traces some of the many ways in which the Severn from Plynlimon to Bridgnorth has changed and developed over the last century
In 1838 Thomas Edmondson, an employee of the fledgling Newcastle & Carlisle Railway, revolutionised the ticket issuing process in Britain and left an enduring legacy: the Edmondson ticket. Purchased as proof of the contract between passenger and railway company, the ticket was a receipt, travel pass and an ephemeral record of almost every train journey ever taken in the British Isles, reflecting the nostalgia of the railways and a period of history when the movement of millions of people brought together England, Ireland, Scotland and Wales. The railways printed millions of tickets for every conceivable journey and category of passenger. Most were destroyed after use, but remarkably many survive, in the care of libraries, museums and collectors, and form the basis of a fascinating hobby.

River Severn: From Source to Sea follows the entire course of the river through Wales and England. It describes the unique and varied countryside in words and high-quality photographs, and includes historic and topographical information and descriptions of footpaths, villages, towns and cities along the way.
Experimental advances in helium atom scattering spectroscopy over the last forty years have allowed the measurement of surface phonon dispersion curves of more than 200 different crystal surfaces and overlayers of insulators, semiconductors and metals. The first part of the book presents, at a tutorial level, the fundamental concepts and methods in surface lattice dynamics, and the theory of atom-surface interaction and inelastic scattering in their various approximations, up to the recent electron-phonon theory of helium atom scattering from conducting surfaces. The second part of the book, after introducing the experimentalist to He-atom spectrometers and the rich phenomenology of helium atom scattering from corrugated surfaces, illustrates the most significant experimental results on the surface phonon dispersion curves of various classes of insulators, semiconductors, metals, layered crystals, topological insulators, complex surfaces, adsorbates, ultra-thin films and clusters. The great potential of helium atom scattering for the study of atomic scale diffusion, THz surface collective excitations, including acoustic surface plasmons, and the future prospects of helium atom scattering are presented in the concluding chapters. The book will be valuable reading for all researchers and graduate students interested in dynamical processes at surfaces.
This book uses asymptotic methods to obtain simple approximate analytic solutions to various problems within mechanics, notably wave processes in heterogeneous materials. Presenting original solutions to common issues within mechanics, this book builds upon years of research to demonstrate the benefits of implementing asymptotic techniques within mechanical engineering and material science. Focusing on linear and nonlinear wave phenomena in complex micro-structured solids, the book determines their global characteristics through analysis of their internal structure, using homogenization and asymptotic procedures, in line with the latest thinking within the field. The book’s cutting-edge methodology can be applied to optimal design, non-destructive control and in deep seismic sounding, providing a valuable alternative to widely used numerical methods. Using case studies, the book covers topics such as elastic waves in nonhomogeneous materials, regular and chaotic dynamics based on continualisation and discretization and vibration localization in 1D Linear and Nonlinear lattices. The book will be of interest to students, research engineers, and professionals specialising in mathematics and physics as well as mechanical and civil engineering.
In 2015 vond aan het Sint-Janscentrum een wetenschappelijk colloquium plaats met internationale sprekers, naar aanleiding van de verjaardag van de val van de Berlijnse Muur. De teksten van de lezingen, die gehouden werden tijdens dit colloquium, zijn nu verzameld in de bundel Secularisation & Europe , een uitgave van uitgeverij Betsaida in samenwerking met de wetenschappelijke uitgeverij van de Pauselijke Universiteit Johannes Paulus II in Krakau.
Encompassing all occupants of aircraft and spacecraft—passengers and crew, military and civilian—Fundamentals of Aerospace Medicine, 5th Edition, addresses all medical and public health issues involved in this unique medical specialty. Comprehensive coverage includes everything from human physiology under flight conditions to the impact of the aviation industry on public health, from an increasingly mobile global populace to numerous clinical specialty considerations, including a variety of common diseases and risks emanating from the aerospace environment. This text is an invaluable reference for all students and practitioners who engage in aeromedical clinical practice, engineering, education, research, mission planning, population health, and operational support.
