This lecture provides a tutorial introduction to the Nyström and locally-corrected Nyström methods when used for the numerical solutions of the common integral equations of two-dimensional electromagnetic fields. These equations exhibit kernel singularities that complicate their numerical solution. Classical and generalized Gaussian quadrature rules are reviewed. The traditional Nyström method is summarized, and applied to the magnetic field equation for illustration. To obtain high order accuracy in the numerical results, the locally-corrected Nyström method is developed and applied to both the electric field and magnetic field equations. In the presence of target edges, where current or charge density singularities occur, the method must be extended through the use of appropriate singular basis functions and special quadrature rules. This extension is also described.

During the Second World War, the Merchant Navy suffered a higher percentage loss than any of the British armed forces, but despite this extraordinary fact few people today are aware of it. In total, 33,000 merchant seamen died, while others were severely injured both physically and mentally. This book is an important volume attempting to dispel the ignorance, and for the first time brings together a wealth of information concerning ship losses, including such details as ships' names, their captains, the route they were lost on, date and positions when lost, loss of life, and many other particulars. A former wartime Merchant Navy man himself, Malcolm presents a compendium of shipping company losses that is staggering in scale. This work will be of great value to shipping enthusiasts and anyone interested in the war at sea.
This is not a book for architects, but for all those that have suffered, consciously and unconsciously, from modern architecture and have wondered how it came about. This was largely due to one man, an architect called Le Corbusier. For some he was a genius, but the truth is he was a sham, a fake, a charlatan whose only gift was for self-publicity. He was the most influential architect of the second half of the twentieth century; his influence overwhelmed the architectural profession on a global scale, who swallowed his publicity whole, and still hold him in awe. For the rest of the world, the mere mortals, his influence was disastrous, as traditional buildings were destroyed and replaced by featureless boxes of varying sizes, imposing a dreariness hitherto unimagined. As usual, it was the poor who suffered most as they were herded into tower-blocks. These were often grouped into estates that ringed many towns and cities, which then degenerated into high-rise slums with all the well-known attendant social problems. This book exposes the myths that surround Le Corbusier, detailing the endless failures of his proposals and his projects. These were due to his profound dishonesty, both as a person and as an architect. His legacy was an architectural profession that believed, and still believe, they were designing buildings based on logic, functionality and honesty whereas they were doing the opposite.

The Sociology of Religion is a comprehensive and wide-ranging introduction to theoretical debates in the sociology of religion, placing these theories in the context of specific religious beliefs and practices. Using examples as diverse as primitive religions, Buddhism, millenial movements, the Protestant Ethic, secularisation, cults and the new religious movements, Malcolm Hamilton demonstrates the multiplicity of religious traditions and enables readers to place their own experiences in a wider context. He draws on both historical and anthropological perspectives in his examination of religious practices and outlines the work of major sociological theorists including Marx, Durkheim, Malinowski and other Functionalists, Frazer and Weber in the examination of world religion, bringing these theories up-to-date. The significance of each theoretical perspective is illustrated by chapters on particular beliefs and practices.
The central role of soil chemistry in the ecosystem and other disciplines is becoming increasingly important. For example the effects of the increased levels of atmospheric carbon dioxide, and accelerated use of pesticides, on soil fertility has been a focus of much high-level debate. This text begins by defining the relationship between soil chemistry and other fields such as plant science and pollution science. A detailed description of the components of soils follows, including inorganic, mineral and organic matter. The book addresses cogent issues such as soil fertility and soil pollution. In a concluding chapter, a review of future analytic advances in the study of soil chemistry is given, emphasising the importance of the soil chemist in equitable and sustainable land use and agricultural policy. The book is an ideal starting point for the student undertaking undergraduate study in the environmental and soil sciences.
This two-volume work explores the management of religious and faith-based organizations. Each chapter offers a discussion of the earliest Christian organizations based on New Testament evidence; a study of managing faith-based organizations; and an exploration of secular management theory in relation to the management of faith-based organizations.
Religious and faith-based organisations constitute a large and important group of organisations. This is the first book to study systematically their characteristics and the distinctive challenges they pose to the people managing them. Malcolm Torry discusses how to define religious and faith-based organisations, how to study them, and the secular context in which they operate in Western Europe and the USA. There are chapters on congregations, denominations, governance, membership, the clergy, leadership, and religious and faith-based organisations' relationship to civil society. The book relies on research-based literature and case studies and contains full bibliographies, making it an essential tool for anyone studying this important new field.
International Mindedness is a practical handbook which offers continuing professional development (CPD) solutions, support and guidance for international schools on a professional and whole-school level. It aims to encourage schools to work towards being 'internationally minded' and to enhance existing international teacher CPD programmes.
This book presents twelve essays by historian David M. Williams, in order to pay tribute to his career. The essays stretch from 1807 through to the end of the nineteenth century, and address both economic and social themes. Topics include maritime trade, deployment of merchant ships, the state regulations concerning shipping, shipwrecks and loss of life, passenger cargoes, slavery, cotton, timber and coffee trades, and the working conditions of seamen over the course of the century. The plight of the maritime labourer is at the core of this collection. The essays primarily focus on British shipping, and firmly places it within an international context. The book is introduced by Lars U. Scholl, followed by two tributes to Williams' career, one by Peter N. Davies, the other by Lewis R. Fischer. Scholl concludes the volume with a thorough bibliography of Williams' maritime writings: books, chapters, and articles.
This book provides a background to the modern geography of the Middle East by tracing the evolution of humanized managed landscapes from the domestication of cereals through to the initiation of the great transformations of the region in the mid-nineteenth century. By examining the natural potential of the region in terms of climate, natural vegetation and physical conditions, and charting the emergence of basic long-lasting traditional economies based on this environment, the author shows how the environment stimulated traditional life styles, which in turn perpetuated and molded the region.
The Admiralty Jurisdiction Regulation Act 105 of 1983 was a radical and far-reaching, as well as overdue, modernisation of South African admiralty law. Described as 'bold, innovative and comprehensive', it introduced - for the first time anywhere in the world - the provisions enabling an action to be pursued by way of the arrest of an associated ship rather than the ship in respect of which the claim lay. This work, by one of South Africa's pre-eminent shipping lawyers, analyses the nature of this novel action. That involves a review of how the jurisdiction came about; its nature and impact; the problems to which it gives rise and the making of some modest suggestions concerning the road ahead.
Twenty years ago the Kentucky General Assembly was one of the least powerful and least effective legislatures in the country, almost entirely dominated by the governor. Over the past two decades the legislature has changed—gradually and with little public attention—into a far more powerful, professional, and independent body. This book is a study of that process of change: its causes, the obstacles encountered, and the political and policy consequences. It is a study of changing relationships between governor and legislature, caused in part by less aggressive gubernatorial leadership and in part by the growing assertion of legislative independence. It is also a study of the men and women who initiated change and who play major roles in the legislature today. One important area of change has been in the kinds of persons elected to the legislature. Today's Kentucky legislators are more professional in their approach to legislative service, serve longer tenures, and are likely to be committed to long-term political careers. They work harder to become known in their districts, and they devote more time to constituency service. In preparing this study, Malcolm E. Jewell and Penny M. Miller interviewed and sent questionnaires to many past and present members of the Kentucky legislature, as well as examining election returns, roll call votes, and committee records. They also traced developments since the 1960s to provide historical perspective. The Kentucky General Assembly is not a "typical" legislature. It is less professional and meets less frequently than those in most states. But trends in the Kentucky legislature are typical of those in other states, and this book puts the changes in Kentucky into national perspective.
The second edition of the Historical Dictionary of the Gulf Arab States comes at a time when the world's attention is riveted on the Middle East. The small states covered in this volume_Bahrain, Kuwait, Oman, Qatar, and the United Arab Emirates (UAE)_possess about 20 percent of the world's total oil reserves. Beyond the strategic and economic importance conferred upon them by their vast oil reserves, the Gulf Arab states are worthy of attention for the inherent interest of their history and culture. No area of the world has yielded more revealing and exciting archaeological finds in the past few decades than these states. Investigations have brought to light extensive evidence of an important culture as old as Egypt of the Pharaohs or ancient Babylon, which was virtually unknown previously except through rare references in the records of other civilizations. This expanded second edition covers the history of the five countries through a chronology broken down by country, a list of acronyms and abbreviations, an introductory essay, a bibliography, and several hundred cross-referenced dictionary entries on important persons, places, and events of each country. Everything from the Abbasids to Zubarah is covered in this essential reference on this increasingly important region of the world.
This lecture presents a modern approach for the computation of Mathieu functions. These functions find application in boundary value analysis such as electromagnetic scattering from elliptic cylinders and flat strips, as well as the analogous acoustic and optical problems, and many other applications in science and engineering. The authors review the traditional approach used for these functions, show its limitations, and provide an alternative "tuned" approach enabling improved accuracy and convergence. The performance of this approach is investigated for a wide range of parameters and machine precision. Examples from electromagnetic scattering are provided for illustration and to show the convergence of the typical series that employ Mathieu functions for boundary value analysis.
