This book was released on 2018-05-29 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we fit Cox proportional hazards models to a subset of data from the Hypobaric Decompression Sickness Databank. The data bank contains records on the time to decompression sickness (DCS) and venous gas emboli (VGE) for over 130,000 person-exposures to high altitude in chamber tests. The subset we use contains 1,321 records, with 87% censoring, and has the most recent experimental tests on DCS made available from Johnson Space Center. We build on previous analyses of this data set by considering more expanded models and more detailed model assessments specific to the Cox model. Our model - which is stratified on the quartiles of the final ambient pressure at altitude - includes the final ambient pressure at altitude as a nonlinear continuous predictor, the computed tissue partial pressure of nitrogen at altitude, and whether exercise was done at altitude. We conduct various assessments of our model, many of which are recently developed in the statistical literature, and conclude where the model needs improvement. We consider the addition of frailties to the stratified Cox model, but found that no significant gain was attained above a model that does not include frailties. Finally, we validate some of the models that we fit.Thompson, Laura A. and Chhikara, Raj S. and Conkin, JohnnyJohnson Space CenterDECOMPRESSION SICKNESS; EXTRAVEHICULAR ACTIVITY; DATA BASES; PARTIAL PRESSURE; HIGH ALTITUDE TESTS; HAZARDS; QUARTILES; PRESSURE; PHYSICAL EXERCISE; NONLINEARITY; NITROGEN; EXPOSURE; ALTITUDE SIMULATION; AEROEMBOLISM

This book was released on 2008-12-16 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite numerous recent studies and exciting discoveries in the field, only limited treatment is available today for the victims of acute neurological injuries. Animal Models of Acute Neurological Injuries provides a standardized methodology manual designed to eliminate the inconsistent preparations and variability that currently jeopardizes advances in the field. Contributed by top experts and many original developers of the models, each chapter contains a step-by-step, proven procedure and visual aids covering the most commonly used animal models of neurological injury in order to highlight the practical applications of animal models rather than the theoretical issues. This intensive volume presents its readily reproducible protocols with great clarity and consistency to best aid neuroscientists and neurobiologists in laboratory testing and experimentation. Comprehensive and cutting-edge, Animal Models of Acute Neurological Injuries is an ideal guide for scientists and researchers who wish to pursue this vital course of study with the proficiency and precision that the field requires.

Available in PDF, EPUB and Kindle. Book excerpt: Ergonomics in Sport and Physical Activity: Enhancing Performance and Improving Safety is also available as an e-book. The e-book is available at a reduced price and allows readers to highlight and take notes throughout the text. When purchased through the Human Kinetics site, access to the e-book is immediately granted when the order is received.Ergonomics in Sport and Physical Activity: Enhancing Performance and Improving Safety is the first text to provide an in-depth discussion of how the principles of ergonomics can be applied in the context of sport and other physical activities to reduce injury and improve performance. The textblends concepts from biomechanics, physiology, and psychology as it shows how ergonomics is applied to physical activity. This comprehensive text outlines methods for assessing risk in and procedures for dealing with stress, eliminating hazards, and evaluating challenges posed in specific work or sport environments. It discusses issues such as the design of effective equipment, clothing, and playing surfaces; methods of assessing risk in situations; and staying within appropriate training levels to reduce fatigue and avoid overtraining. The text not only examines sport ergonomics but also discusses ergonomic considerations for physically active special populations. Ergonomics in Sport and Physical Activity explains what ergonomics is, how ergonomists solve practical problems in the workplace, and how principles of ergonomics are applied in the context of sport and other physical activities when solving practical problems related to human characteristics and capabilities. The text shows readers how to improve performance, achieve optimal efficiency, enhance comfort, and reduce injuries by exploring topics such as these: Essential concepts, terms, and principles of ergonomics and how these relate to physical activity Physical properties of the body and the factors limiting performance Interactions between the individual, the task, and the environment Injury risk factors in relation to body mechanics in various physical activities Injury prevention and individual protection in the review of sports equipment and sports environments Comfort, efficiency, safety, and details of systems criteria in equipment design This research-based text uses numerous practical examples, figures, charts, and graphs to bring the material to life. In addition, descriptions of technological advances show where we have been and how technology has advanced the field. Through the book’s discussion of the various stressors and adaptive mechanisms, readers will learn how to cope with various environmental conditions. They will also learn how various training modes can be used to alter sport-specific capabilities and enhance performance. Presenting a wide range of approaches, theoretical models, and analytical techniques, Ergonomics in Sport and Physical Activity: Enhancing Performance and Improving Safety illustrates the potential for ergonomics to be extended across recreation, competitive sport, and physically active work environments. Bridging the gap between ergonomics and exercise science, this unique text will assist both health care and exercise professionals in developing an improved awareness of how human capabilities are best matched to physical activities.

Download or read book The Last Dive written by Bernie Chowdhury and published by Harper Collins. This book was released on 2012-01-03 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tragic account of the father-son dive team who met with disaster while exploring the wreck of a German U-boat off the coast of New York. Chris and Chrissy Rouse, an experienced father-and-son scuba diving team, hoped to achieve widespread recognition for their outstanding but controversial diving skills. Obsessed and ambitious, they sought to solve the secrets of a mysterious, undocumented World War II German U-boat that lay under 230 feet of water, only a half-day’s mission from New York Harbor. In doing so, they paid the ultimate price in their quest for fame. Bernie Chowdhury, himself an expert diver and a close friend of the Rouses’, explores the thrill-seeking world of deep-sea diving, including its legendary figures, most celebrated triumphs, and gruesome tragedies. By examining the diver’s psychology through the complex father-and-son dynamic, Chowdhury illuminates the extreme sport diver’s push toward—and sometimes beyond—the limits of human endurance. Praise for The Last Dive “Superbly written and action-packed, The Last Dive ranks with such adventure classics as The Perfect Storm and Into Thin Air.” —Tampa Tribune “[A] captivating account of sport diving.” —Publishers Weekly “Excellently written and a real “grabber” to read, the book includes much information about the history, equipment, and people who make up the world of extreme or “technical” diving. This book should be read by any diver thinking of getting involved in wreck, cave, deep, or mixed-gas diving.” —Library Journal
Download or read book Emergencies in Urology written by M. Hohenfellner and published by Springer Science & Business Media. This book was released on 2007-08-18 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive textbook covering one of the few remaining blind spots on the map of urological literature. To date only a small number of publications have been dedicated to the topic of urgent and emergent problems in urology, important though they are in everyday clinical medicine. The editors are both internationally recognized urological experts and have made the effort to present an in-depth study into virtually every possible urgent urological situation with which a urologist may be confronted today. Thus the book includes chapters on topics such as urological trauma, urosepsis, urinary obstruction, oncological emergencies, intra- and postoperative complications, acute problems in children, and many more.
