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 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. Keywords: Weapons effects; Mathematical models; Anatomical models; Occupational diseases; Exposure physiology, Protective clothing.

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.

Download or read book Introduction to Bioengineering written by Y C Fung and published by World Scientific Publishing Company. This book was released on 2001-05-04 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioengineering is attracting many high quality students. This invaluable book has been written for beginning students of bioengineering, and is aimed at instilling a sense of engineering in them. Engineering is invention and designing things that do not exist in nature for the benefit of humanity. Invention can be taught by making inventive thinking a conscious part of our daily life. This is the approach taken by the authors of this book. Each author discusses an ongoing project, and gives a sample of a professional publication. Students are asked to work through a sequence of assignments and write a report. Almost everybody soon realizes that more scientific knowledge is needed, and a strong motivation for the study of science is generated. The teaching of inventive thinking is a new trend in engineering education. Bioengineering is a good field with which to begin this revolution in engineering education, because it is a youthful, developing interdisciplinary field.
