Africa has been and currently is the site of numerous conflicts and crises. Authors previously wrote of these as specifically African problems or the problems of Europeans in Africa, but newer scholarship on other aspects of Africa has come to stress the interconnectness of Africa and the wider world. Still, it has often been limited to studies of isolated instances within African countries, with little-to-no connection to greater patterns of international power and violence. This volume explores the historical and present local and international dimensions of the myriad security crises in Africa, from the role of international relations during liberation to multination efforts against piracy.

Stone inscriptions are the most important written source for 5th-7th century western-British history. Against a background for Old World prehistory and the classical civilizations, this book focuses on the inscribed memorial stones of Demetia (south-west Wales, modern-day Dyfed) and Dumnonia (Devon, Cornwall and part of Somerset). The author looks at cultural change after AD 400 by analyzing the evidence or "messages" left on memorial stones. The invention of the ogam script in Ireland and its use, with implications for both paganism and Christianity, on such stones is examined. A group of chapters is devoted to a praticular reconstruction of events in south-west Wales between AD 400 and 600 - the establishment of an Irish-decended kingdom of Dementia. The author demonstrates that the Dementians adopted first Latinity (use of Roman names, ets) and only then Christinity, influenced by sub-Roman native kingdoms to the east. The author then traces a remarkable "venture to the interior" - the foundation of a small Dementian kingdom in the upper Usk valley, and examines documentary evidence for the first settler-king - Brychan - and, as monk and saint, his connection with Lundy Island (in the Bristol Channel) and north Devon. Evidence for a post-Roman native kingdom in Cornwall, Devon and part of Somerset is next considered, as is minor Irish settlement in west Cornwall around the year 400, and an isolated introduction of Christianity from 5th-century Gaul. Inscribed stones show that the conversion of Dumnonia to Christianity - though field-work has revealed that, far from being a Land of Saints, the deep south-west did not become Christian until well into the 6th century.

Suitable for both aspiring process technicians and active process technology professionals, this wide-ranging guide provides a thorough grounding in the history, science, technology, equipment, systems, operations, and troubleshooting principles associated with modern manufacturing. Following years of widespread use and testing, INTRODUCTION TO PROCESS TECHNOLOGY, Fourth Edition, is a proven product featuring a logical sequence of topics—including safety, instrumentation, applied physics and chemistry, and quality control—aligned to the structure of accredited college courses and professional training programs. Technically accurate and up to date, the Fourth Edition remains affordable, reader-friendly, and highly visual, with ample illustrations and photographs to make complex technical concepts easier to understand and apply.

For the first time, process technicians have a resource designed specifically for them that will provide a comprehensive, thorough overview of modern troubleshooting methods and models. Process Technology Troubleshooting utilizes a simple to complex approach that encourages readers to master basic concepts before progressing to more advanced ones for increased comprehension. The book covers troubleshooting models that apply concepts from advanced instrumentation, the control loop, and process equipment and systems, and includes coverage of such processes as a simple pump-around and feed system, compressor system, heat transfer system, cooling tower system, boiler system, furnace system, distillation system , stirred reactor system, and separations system. Each of these systems have operational information, set points, and start-up procedures. These sections include "what-if" scenarios and detailed illustrations. Process Technology Troubleshooting is an invaluable resource and reference for any novice, training manager or experienced process technician.

First of a two-part issue dealing with Cancer Emergencies by Drs. Mohamud Daya and�Charles Thomas.��Topics with include: "Spinal Cord Compression," "Cerebral Edema," "Acute Renal Failure," "Electrolyte Disorders," and more!

This issue provides the reader with a summary of evidence-based therapies of how to manage emergency care for cancer disorders. Articles are dedicated to specific presentation syndromes, such as malignant epidural spinal cord compression, superior vena cava syndrome, and airway obstruction. These reviews update the reader on evidence-based therapies for these entities and highlight the emerging role of stent therapies. This issue also includes articles dealing with the neurological, renal, and metabolic (electrolyte and adrenal) emergencies encountered in the cancer patient. Also addressed are selected gastrointestinal presentations commonly encountered in cancer patients, such as the acute abdomen, gastrointestinal bleeding, and hepatic encephalopathy. The issue concludes with several articles dedicated to hematologic considerations including venous thrombosis, acquired bleeding disturbances, and myeloproliferative/hyperviscosity syndromes.
