The 4 volumes in this ambitious project are: • Volume 1: Practice, Analysis, and Methodology   • Volume 2: Theories and Solutions • Volume 3: Applications for Mental Disorder Treatments • Volume 4: Applications for Physical Disorder Treatments This ground-breaking set of books is a unique and state-of-the-art study that only appears here, within these pages.  A fascinating study for the engineer, scientist, and pharmacist working in the pharmaceutical industry and interested in sustainability, it is also a valuable textbook for students and faculty studying these subjects.
