This is the only up-to-date systematic review of normal human response to upright posture and lower body negative pressure (LBNP). It analyzes the key factors that influence postural tolerance, such as physical fitness, weightlessness, age, and sex. It also provides extensive details on the circulatory changes that have occurred during U.S. and Soviet manned space flights. The text is brilliantly illustrated with diagrams, tables, and comments on circulatory methods. Readers will discover some information which has never before been published. This one-of-a-kind volume also reviews the diagnosis and treatment of orthostatic hypotension-an extremely common orthostatic disorder. Circulatory Response to the Upright Posture is the first available literature since 1982 of human physiological and pathophysiological aspects of postural tolerance. A wide variety of readers will find this title interesting and of value. Circulatory physiologists, cardiologists, and everyone with an interest in exercise physiology, aging, space physiology, and environmental physiology will especially benefit from this writing.
This exciting and unusual World War Two book contains the biographies of young men from the United States and Commonwealth Countries who flew through enemy infested skies in a civilian passenger plane known as the Hudson Bomber. The author portrays not only flyers but their families as they face the unfolding fates of their youngsters flying in Royal Air Force Coastal Command Squadrons. Much of the book is written from primary research material: personal diaries, log books, a large number of photographs and anxious letters home to parents and wives and friends. "Searching For The Hudson Bombers" rings loudly with authenticity of how World War Two impacted people at an intimate and personal level. Flying duties of these patriotic youth from America, Canada, Australia, New Zealand and South Africa are portrayed in a range of activities from over the North Sea to the Mediterranean. The Hudson air crews bomb shipping and search in all kinds of nasty weather for submarines, cover convoys and look for downed air craft. Sub themed in the text are the disappointing activities of politicians, corporations, financial institutions and religious bureaucracy. One will not find much grand strategy as planned by Presidents, Prime Ministers and Generals in, "Searching For The Hudson Bombers." This is a book about unheralded flyers who risked their lives each time they went aloft in a less than reliable aircraft, the Hudson Bomber. This intriguing and intensely researched work exposes the truly human side of one of history's most cataclysmic events. An excellent read!" Major General (Ret'd) Lewis W. MacKenzie OStJ,OOnt,MSC,CD.

This book presents essential information for the development of a comprehensive sustainable energy policy. It examines the diverse types of energy, their resource abundance and the material needs to develop and use them, and how communities and cities can better control their own destinies by locally managing energy use and generation. This approach does not suggest the undoing of existing infrastructures and energy providers, but rather a cooperative transition from national-regional energy management to a more local-centered system. The information is the foundation for eight specific legislative initiatives necessary for a national comprehensive sustainable policy that can both facilitate and drive the process of evolution from a carbon-energy economy to a sustainable renewable energy future.
This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do. The basic assumption is that vision depends on the eye which is connected to the brain. The author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision -- and what this book is about.
