During the century 1850-1950 Vancouver Island attracted Imperial officers and other Imperials from India, the British Isles, and elsewhere in the Empire. Victoria was the main British port on the north-west Pacific Coast for forty years before the city of Vancouver was founded in 1886 to be the coastal terminus of the Canadian Pacific Railway. These two coastal cities were historically and geographically different. The Island joined Canada in 1871 and thirty-five years later the Royal Navy withdrew from Esquimalt, but Island communities did not lose their Imperial character until the 1950s."--P. [4] of cover.
During the last two decades, the production of polymers and plastics has been increasing rapidly. In spite of developing new polymers and polymeric materials, only 40~60 are used commercially on a large scale. It has been estimated that half of the annual production of polymers is employed outdoors. The photochemical instability of most polymers limits their outdoor application as they are photodegraded quickly over periods from months to a few years. To the despair of technologists and consumers alike, photodegradation and environmental ageing of polymers occur much faster than can be expected from knowledge collected in laboratories. In order to improve polymer photostability there has been a very big effort during the last 30 years to understand the mechanisms involved in photodegradation and environmental ageing. This book represents the author's attempt, based on his 25 years' experience in research on photodegradation and photo stabilization, to collect and generalize a number of available data on the photodegradation of polymers. The space limitation and the tremendous number of publications in the past two decades have made a detailed presentation of all important results and data difficult. The author apologizes to those whose work has not been quoted or widely presented in this book. Because many published results are very often contradictory, it has been difficult to present a fully critical review of collected knowledge, without antagonizing authors. For that reason, all available theories, mechanisms and different suggestions have been presented together, and only practice can evaluate which of them are valid.
Among the more than 200 known chapters of the Book of the Dead genre chapters 7 and 39 are entirely devoted to Apopis, the representative of darkness and chaos in Egyptian mythology. The present edition contains a translation of and extensive commentary on the text of the longer of the two, chapter 39, with a hieroglyphic transcription of six representative manuscripts from the 18th Dynasty down to the Ptolemaic period. Apopis, the rebel against cosmic order, is traditionally represented as a giant serpent and documented in a great number of cosmological and ritual texts of the Middle Kingdom and later. He is the ever-returning opponent of the sun god Re', trying to halt the course of the sun boat. His emerging from the chaos waters is especially feared at night. Although time and again the attack is repelled and Apopis driven back or bound and annihilated by the sun god's helpers, he always resurges and continues to be a threat to the cosmic balance. Precisely this is the theme of chapter 39, which is less a description of events than a violent vociferation on the part of gods and goddesses against the enemy. An attempt is made in the commentary to reconstruct the course of events.
The wild rush of action in this classic frontier adventure story has made The Last of the Mohicans the most popular of James Fenimore Cooper’s Leatherstocking Tales. Deep in the forests of upper New York State, the brave woodsman Hawkeye (Natty Bumppo) and his loyal Mohican friends Chingachgook and Uncas become embroiled in the bloody battles of the French and Indian War. James Fenimore Cooper’s historical imagination is profound, his creative use of the gothic landscape is uniquely American, and his infl uence on plot and characterization in American fi ction is pervasive and extensive.
Hyaluronan and its derivatives has developed very quickly in the last few years from a scientific novelty into an important new material for a diverse range of medical and biomaterial applications. This landmark conference focused on developments and applications in the use of hyaluronan in tissue repair and reconstruction, drug delivery systems, anti-cancer treatments and joint recovery and engineering. The entire range of hyaluronan progress is covered in depth by the more than 135 individual papers: Analytical chemistry Structural elucidation and basic chemistry Electron microscopy and atomic force microscopy Production, purification and characterisation Quality in production systems Chemical modification Derivatives and properties Cross-linking Free radical modification Physical characterisation Rheology Aggregation phenomena Interaction with water and solution properties Cell biology Control and regulation of HA synthases Cell surface chemistry HA cell receptors and cell signalling Interaction with proteins and other biological ligands Biophysical aspects Effects on pain receptors Neurobiology Role in organisation of extracellular matrix Role in development (embryogenesis): cell movement/migration Medical applications Uses in cartilage and wound repair Inflammation Wound regenerative healing Surgery and tissue engineering Viscosupplementation / osteoarthritis Viscoaugmentation and viscoprotection Anti-adhesion applications Brug delivery systems Binding onto tumour cells and metastases Outlines the proceedings of the landmark conference which focused on key developments and applications in the use of hyaluronan in tissue repair and reconstruction, among other uses The entire range of hyaluronan processes is dealt with in depth by more than 135 individual papers presented in two volumes Covers analytical chemistry, chemical modification, physical characterisation, cell biology and medical applications
Fenimore Cooper`s fictitious frontier hero Bumppo is never called by his name, but is instead referred to as “the trapper” or “the old man”. It depicts Natty in the final year of his life still proving helpful to people in distress on the American frontier. The book frequently references characters and events from the two books previously published in the Leatherstocking Tales as well as the two which Cooper wouldn’t write for more than ten years.
The text is intended as supplementary reading for fisheries workers, especially in developing countries, who do not always have ready access to current literature on applied marine ecology. An attempt is made to develop a wide range of concepts in a form that will hopefully encourage their incorporation into a practical, decision-making context. The food web and associated trophic interactions form the principal theme, in an approach that gives equal emphasis to qualitative, as well as the less easily measured quantitative considerations. An attempt is made to illustrate the consequences of the aggregated nature of much of marine production, as well as the subsequent dispersal of production in space and time, and how these processes affect the potential for economic harvest of commercial components of the ecosystem. Separate sections touch on environmental influences on production, relevant spatial and temporal scales for ecosystem analysis, life history strategies, diversity and stability, the concepts of the ecological niche, the community and the assemblage, and outline some first steps towards quantifiying production in marine ecosystems. Different approaches to representing trophic and other interactions are discussed, with examples from the literature. Reference is made to several ecological subsystems, in order to illustrate the main concepts presented. These include the mangrove ecosystem, the arcto-boreal macrophyte community, a mediterranean demersal fish assemblage, and the oceanic ecosystem associated with high seas tuna stocks. In practical terms, it is concluded that the first and simplest approach to multispecies resource management is not necessarily the manipulation of individual food web components, but the identification, mapping and conservation of critical habitats, especially centres of local production, and their associated ecological dissipation structures.
This important work, edited by an expert on terrorism, focuses on the 21st-century struggle for strategic influence and ways in which states can neutralize the role of new media in spreading terrorist propaganda. In an era where anyone can have access to the Internet or other media forms that make widespread communication easy, terrorists and insurgents can spread their messages with complete freedom, creating challenges for national security. Influence Warfare: How Terrorists and Governments Fight to Shape Perceptions in a War of Ideas focuses on the core of the ongoing struggle for strategic influence and, particularly, how states can counter the role media and the Internet play in radicalizing new agents of terrorism. As the book makes clear, governments need to find ways to effectively confront non-state adversaries at all levels of the information domain and create an understanding of strategic communications within a broad range of technologies. The essays from the international group of authors who contributed to this work offer a deeper understanding of the ongoing struggle. Influence Warfare also provides a set of case studies that illustrate how the means and methods of strategic influence can impact a nation's security.
An eclectic collection of scientific papers and popular science articles on Darwin and Darwinian evolution, beautifully illustrated. Topics range from Darwin's time spent in Edinburgh to the place of music in his life and works, his struggle with the impact of his ideas and the way that they have been subsequently used. What role has water location played in African evolution? Which well-known zoologist anonymously wrote a scathing review of The Origin of Species? What do contemporary academics think of Darwin's legacy? What role will Darwinism play in our future? Here are the answers to these and many more questions about Darwin and Darwinian evolution.
Reprint of a classic work of ancient military history Traces the origins of Sparta's unique training, tactics, and organization that made it the master of Greek battlefields Clear analysis of battles such as Thermopylae, Plataea, Mantinea, and Leuktra Spartan warriors continue to influence modern militaries, including the U.S. Marine Corps
