The Relationship Between Selected Blast-wave Parameters and the Response of Mammals Exposed to Air Blast by Donald R. Richmond,Edward G. Damon,E. Royce Fletcher,I. Gerald Bowen,Clayton S. White Pdf
For personnel standing or prone-side-on to the charge when it is detonated at or near the surface, the side-on incident plus dynamic pressures become the effective pressure; however, with orientations end-on in this situation, only the side-on incident pressure appears to be the maximal effective pressure.
With the contribution from more than one hundred CNS neurotrauma experts, this book provides a comprehensive and up-to-date account on the latest developments in the area of neurotrauma including biomarker studies, experimental models, diagnostic methods, and neurotherapeutic intervention strategies in brain injury research. It discusses neurotrauma mechanisms, biomarker discovery, and neurocognitive and neurobehavioral deficits. Also included are medical interventions and recent neurotherapeutics used in the area of brain injury that have been translated to the area of rehabilitation research. In addition, a section is devoted to models of milder CNS injury, including sports injuries.
The Relation Between Eardrum Failure and Blast-induced Pressure Variations by Clayton S. White,Donald R. Richmond,I. Gerald Bowen Pdf
In field and laboratory experiments designed to study overall blast effects, incidental observations were made of the ears of over 490 animals. Those inside structures were exposed to a variety of 'atypical' blast waves. Those located inside shock tubes or in the open when high explosives were detonated were exposed to fairly 'typical' wave forms. An attempt was made to relate the incidence of eardrum rupture to various elements of the measured pressure-time curves. The association was not the same for 'typical' and 'atypical' wave forms. Within the limits of the meager differences were noted and discussed with emphasis on the apparent wide variability in tolerance for which an explanation was proposed.
Neurotrauma: A Comprehensive Textbook on Traumatic Brain Injury and Spinal Cord Injury aims to bring together the latest clinical practice and research in the filed of two forms of trauma to the central nervous system: namely traumatic brain injury (TBI) and spinal cord injury (SCI). Nationally, more 1.9 million Americans sustain a traumatic brain injury annually. In parallel, there are an estimate of 12,000 new cases of SCI in the United States annually. In addition, approximately 1.2 million people live with paralysis due to SCI. In recent years, dramatic advancements in the field have resulted in much improved outcomes for patients and higher standards of care. This volume details the latest research and clinical practice in the treatment of neurotrauma, in a comprehensive but easy-to-follow format. Neurotrauma is a valuable resource for any clinician involved in caring for TBI and SCI patients, clinical research professionals, researchers, medical and graduate students, and nurse specialists.
The Acute Effects of Air Blast on Pulmonary Funcion in Dogs and Sheep by Damon Edward G.,John T. Yelverton,Ulrich C. Luft,Kabby Mitchell (Jr.),Robert K. Jones Pdf
Pulmonary function tests were conducted before and after exposure of animals to air blasts produced in shock tubes or by high explosives. Pressure- time measurements were made with piezoelectric pressure transducers during each air-blast exposure. Blood samples were obtained without anesthesia from an indwelling arterial catheter. The blood PO2, PCO2, and pH and the end-tidal and mixed expired CO2, O2, and N2 gas concentrations were measured for subjects breathing air and oxygen. There were increases in the alveolar-arterial O2 differences and venous admixture which generally correlated with the extent of blast-induced lung damage. The threshold for lung injury resulting in increased venous admixture in sheep was about 20 psi for reflected overpressures of 'long' duration. Pressures above 43 psi usually caused severe lung damage in which the venous-arterial shunt exceeded 30 percent of the cardiac output, a condition in which the arterial oxygen tension was below the level required for full saturation of the hemoglobin even with animals breathing pure oxygen.

Gulf War and Health by Institute of Medicine,Board on the Health of Select Populations,Committee on Gulf War and Health: Long-Term Effects of Blast Exposures Pdf
Since the United States began combat operations in Afghanistan in October 2001 and then in Iraq in March 2003, the numbers of US soldiers killed exceed 6,700 and of US soldiers wounded 50,500. Although all wars since World War I have involved the use of explosives by the enemy, the wars in Afghanistan and Iraq differ from previous wars in which the United States has been involved because of the enemy's use of improvised explosive devices (IEDs). The use of IEDs has led to an injury landscape different from that in prior US wars. The signature injury of the Afghanistan and Iraq wars is blast injury. Numerous US soldiers have returned home with devastating blast injuries and they continue to experience many challenges in readjusting to civilian life. Gulf War and Health, Volume 9 is an assessment of the relevant scientific information and draws conclusions regarding the strength of the evidence of an association between exposure to blast and health effects. The report also includes recommendations for research most likely to provide VA with knowledge that can be used to inform decisions on how to prevent blast injuries, how to diagnose them effectively, and how to manage, treat, and rehabilitate victims of battlefield traumas in the immediate aftermath of a blast and in the long term.

Safety Design Criteria for Industrial Plants by Antonio Naviglio,Maurizio Cumo Pdf
First published in 1989: A generalization and rationalization of the main safety design criteria and safety analysis methodologies developed in nuclear aerospace and chemical engineering is presented in two comprehensive volumes. The concepts of risk, damage and probability of hazardous events are introduced. Risks connected with the use of main harmful substances are quantitatively identified. The methods employed for the safety analyses are described, together with the methodologies for seismic analyses and for Probabilistic Risk Assessment. The main criteria for protection of plants from internal and external events are introduced and described. In addition, the problem of emergency planning is considered. This book is particularly intended for engineers working in the nuclear field, in chemical industries, in industrial plants, in fuel storages and with high-risk substances, as well as for engineers operating in licensing organizations and for inspectors.
