This book was released on 1985 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the Blast OverPressure (BOP) program is to understand the mechanisms by which biological organs are injured so that a Damage Risk Criteria (DRC) for humans can be defined in terms of blast parameters. In addition to the various experimental projects, mathematical models have been developed to understand the underlying mechanisms, correlate mechanical response and observed injury, and to provide a way to extrapolate animal experimental studies to the prediction of human exposure safety guidelines. This report documents the construction of mathematical models to study animal response to external blast. Based on sheep anatomy a simplified 16- element three-dimensional model was constructed to capture the gross body response. A refined two-dimensional model was then constructed to follow wave propagation inside the thorax and to identify locations subjected to the greatest stress. Keywords: Wounds and injuries; Blast loads; Blast waves.

This book was released on 1985 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blast waves are known to cause injuries to internal organs, e.g., lung, gastrointestinal tract, ear, and larynx. To explore the possibility of using body covering as a means of protection, Clemedson and Jonsson 1 covered rabbits with rigid and soft material and exposed the animals to blast waves in shock tube and free field explosion experiments. They found that the rigid material protected the animal from lung injury. The soft coverings, however, were found to produce increased loading and aggravate the lung injury. Both peak pressure and rate of pressure rise in the thorax were found to be considerably higher in their experiments. Nevertheless the underlying mechanism causing such phenomena was not explained. From these results it appears that material coverings can increase the blast loading at the body surface, which, in turn, can cause increased ITP and higher risk of blast injury. Since ITP has been correlated with the severity of blast injury, understanding of the effect of vest material on blast wave transmission, reflection, and absorption is an important step toward the design of a protecting device.

This book was released on 1985 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edema formation is the most evident injury of the lung when it is subjected to an impact load. A quantitative evaluation of the lung injury is of interest. In this report we describe a gravimetric method which is based on first establishing an isogravimetric condition of the lung before the impact load is applied. Excised rabbit lung was tested. The total lung weight was measured continuously so that the rate of progress of edema was obtained. The edema rate provides a quantitative measure of lung injury. It is shown that the rate of edema formation depends on the rigidity of the surface on which the lung rested. If the lung was freely supported on a lightweight soft cloth the edema produced by and impact was much less than that produced in the same lung supported on a rigid plate. This undoubtedly indicates that the reflection of a stress wave on a hard surface imposes a more severe condition for lung injury. It is also shown that the initial velocity of impact at the surface of the lung is a principal parameter to correlate with the rate of edema formation after impact. Keywords: Wounds and injuries.

This book was released on 2013-03-09 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 1985, NATO sponsored an Advanced Study WOl'kshop entitled, "Noise-Induced Hearing Loss: Basic and Applied Aspects." Tne meeting was held in a mountain retreat near Lucca, Italy and was attended by scientists, clinicians, and public officials from 12 countries. This was the third in a series of such conferences organized by the authors. The first two were supported by the United States National Institute of Occupational Safety and Health; their proceedings were published as "The Effects of Noise on Hearing" in 1976 and "New Perspectives on Noise-Induced Hearing Loss" in 1982. The Organizing Committee approached NATO because it was felt that the problem of noise was common to all industrialized countries and was an especially serious problem for the military. Thus, the NATO sponsorship and the Italian site of the meeting were part of the Organizing Committee's plan to obtain an international and thorough repr'esentation on the problem of noise-induced hearing loss. The NATO meeting and proceedings followed the format of the previous two symposia with an initial focus on the anatomical and physiological disturbances resulting from noise-induced hearing loss. This was followed by sections devoted to studies of a more applied nature involving general auditory performance in noise, issues associated with the establishment of noise-exposure criteria, nonauditory effects of noise, and the interaction of noise with other agents.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest developments in the field of biomedical engineering and includes practical solutions and strictly scientific considerations. The development of new methods of treatment, advanced diagnostics or personalized rehabilitation requires close cooperation of experts from many fields, including, among others, medicine, biotechnology and finally biomedical engineering. The latter, combining many fields of science, such as computer science, materials science, biomechanics, electronics not only enables the development and production of modern medical equipment, but also participates in the development of new directions and methods of treatment. The presented monograph is a collection of scientific papers on the use of engineering methods in medicine. The topics of the work include both practical solutions and strictly scientific considerations expanding knowledge about the functioning of the human body. We believe that the presented works will have an impact on the development of the field of science, which is biomedical engineering, constituting a contribution to the discussion on the directions of development of cooperation between doctors, physiotherapists and engineers. We would also like to thank all the people who contributed to the creation of this monograph—both the authors of all the works and those involved in technical works.
