If you or someone you know is diagnosed with Parkinson's, how do you cope with the denial, anger and fear, as well as the symptoms? I haven't discovered a cure for Parkinson's, but I have found a way to tame many of its debilitating symptoms and return to a more normal existence.

This monograph is concerned with mathematical aspects of compartmental an- alysis. In particular, linear models are closely analyzed since they are fully justifiable as an investigative tool in tracer experiments. The objective of the monograph is to bring the reader up to date on some of the current mathematical prob- lems of interest in compartmental analysis. This is accomplished by reviewing mathematical developments in the literature, especially over the last 10-15 years, and by presenting some new thoughts and directions for future mathematical research. These notes started as a series...
