Although the many social, psychologic and economic causal mechanisms contributing to aggression have been reasonably well-understood for a number of years, the correlated physiological, biochemical, endocrinological and neurochemical changes taking place in an organism that is either the aggressor or the recipient of aggression have not been studied extensively, and the limited available data in the past have often been in con­ siderable conflict. This short volume contains papers presented at a special symposium, "The Physiology of Aggression and Defeat," during the MAS meetings in Dallas, Texas, in December, 1968. The Physiology of Aggression and Defeat At a time when we need to understand the basic mechan­ isms underlying various forms of aggression, these papers report progress toward this goal.

This book is intended to provide a practical introduction to high-speed, high-efficiency liquid chromatography. The development of liquid chromatography has proceeded in fits and starts over many years and in alliance with various scientific disciplines.

Determination of the distribution of monomer se­ quences by molecular size has become possible through combined gel permeation chromatography and spectroscopic analysis. Nuclear magnetic resonance, electron spin resonance and MOssbauer spectroscopy started making sig­ nificant contributions to polymer chemistry in the early sixties. The relationship between the chemistry of polymers and performance can be determined from changes in chemical structure and orientation after curing, degradation, or physical or thermal manipulation of the polymers. Polymer Characterization Interdisciplinary Approaches.

The general indications are that while the aggressor learns to survive and adapts readily to the fighting process, the vanquished, if he does not die, maintains an existence highlighted by severe and extensive changes in all physiologic and psycho­ logic systems.

However, the recent availability of the laser as a light source has brought sig­ nificant improvements in the more conventional optical methods such as schlieren photography and interferometry as reported here in Alcock's paper.

The general indications are that while the aggressor learns to survive and adapts readily to the fighting process, the vanquished, if he does not die, maintains an existence highlighted by severe and extensive changes in all physiologic and psycho­ logic systems.. We cannot make sweeping generalizations to the human organism from the results of non-human animal experimentation.

However, the recent availability of the laser as a light source has brought sig­ nificant improvements in the more conventional optical methods such as schlieren photography and interferometry as reported here in Alcock's paper. This volume is based on material prepared by the contributors to the symposium on "Progress in Gas Dynamic Research by Optical Methods", held on May 25-26, 1970 in the Department of Mechanical and Aerospace Engineering at Syracuse University.
