Aviation technology progressed by leaps and bounds during the late 1930s and early 1940s. Although much of this was due to advances in airframe design, much less appreciated is the role of aero engine development. This book focuses on this aspect, particularly German piston aero engine design and development, which has been generally under researched and under published compared to Allied piston aero engines. It covers key piston aero engines such as those produced by Daimler-Benz, BMW, and Junkers, as well as less well appreciated engines such as those produced by Siemens, Argus, and Hirth. It also covers turbojets and rockets, particularly the Junkers Jumo 004 and Walter 109-509 that powered the infamous Messerschmitt Me 262 and Me 163 jet and rocket fighters. Finally, the book concludes with tables comparing Allied and German piston engines, a glossary of key terms, and a bibliography....
This book explores the influences for ethnopolitical groups to act internationally in advancement of their group interests. Yu-Wen Chen proposes an ecological approach to comprehend ethnopolitical contention. In essence, she argues that transnationalizing the contention has the merit of raising the ethnopolitical group's salience and helps to create niches that can demarcate one group from other claim-making groups in a society. Quantitative analysis of the primary data from the European Survey of Ethnopolitical Groups (ESEPG) and qualitative case studies confirm that although some ethnopolitical groups have presented their issues in the international arena, the domestic realm is still the main locus for ethnopolitical contention to occur. Salience, resources, domestic and international opportunity structures affect ethnopolitical groups' international engagement. This book is an essential volume for anyone interested in ethnic mobilization, social movements, and transnationalization.
Innumerable books have been published on the two most famous fighter aircraft of all time, the Supermarine Spitfire and the Messerschmitt Bf109. But books setting out to tell the story of both aircraft are very much rarer - probably fewer than the fingers of one hand. Yet their joint story is one which bears retelling since both were essential to the air campaigns of World War Two.Incredibly, the men who designed them lacked any experience of designing a modern fighter. R J Mitchell had begun his career working on industrial steam locomotives, Willy Messerschmitt had cut his aeronautical teeth on light and fragile gliders and sporting planes. Yet both men not only managed to devise aircraft ...
«Война моторов» — цикл исследований, посвящённых советским танкам, авиамоторам и самолётам периода Второй мировой войны. При написании книги Андрей Мелехов в первую очередь ставил перед собой задачу понять, насколько технически подготовленной оказалась Красная Армия к началу Большой войны. Хватало ли ей танков, самолётов и артиллерийских тягачей? Насколько хороши были танки Б...

Human Prion Diseases, Volume 153 is designed to update the reader on the latest advances and clinical aspects of prion diseases. The book is organized into five sections, including the pathophysiology of prions and a description of animal and human diseases. This is followed by detailed reports on recent advances in diagnosis strategies for the development of novel anti-prion molecules and possible designs of clinical trials in such a rare disease. An introductory chapter gives an extensive historical background of prion research, with a final chapter highlighting recent progress, and more importantly, unsolved problems. - Offers an authoritative overview of prion diseases in humans, detailing the pathogenesis of the disease, clinical investigations, and the diagnosis of both the genetic and acquired forms - Provides clarity and context by presenting prion diseases in relation to other neurodegenerative diseases in humans - Emphasizes the unique properties of prion diseases and consequent problems they can cause, both clinically and in public health terms
