This book focuses on the first two steps of this process with chapters exploring topics such as chemical element abundances; galaxies, galactic magnetic fields and cosmic rays; galactic chemical evolution.
Dr. Vladivoj (Vlado) Valkovic, a retired professor of physics, is a fellow of the American
Physical Society and Institute of Physics (London). He has authored 22 books (from Trace
Elements (Taylor & Francis, Ltd., 1975) to Radioactivity in the Environment (Elsevier, 1st
Edition 2001, 2nd Edition, 2019)) and more than 400 scientific and technical papers in the
research areas of nuclear physics and applications of nuclear techniques to trace element
analysis in biology, medicine and environmental research. He has lifelong experience in
the study of nuclear reactions induced by 14 MeV neutrons. This research has been done
through coordination and works on many national and international projects, including
US–Croatia bilateral, NATO, IAEA, EU-FP5, EU-FP6 and EU-FP7 projects.
He had worked as a professor of physics at Rice University, Houston, Texas; as a Head
