Professor Bernd Heb, University of Erlangen, has a special focus in his research on relativistic effects and the development of tools needed to study them.. Professor Hans-Joachim Werner, University of Stuttgart, has for many years pioneered developments of multi-configurational SCF and coupled-cluster methods and applied them to a wide variety of chemical problems. The book provides the equations, and approaches for their solution, which can be applied to complicated multilevel quantum systems. It also gives the background theory for application to isolated atoms or trapped ions, simple molecules and atoms embedded in by: The detailed analysis of positive and negative drug impacts is subsumed in the science of pharmacology but has obvious overlap and relation to toxicology both in its tenets and methodologies but also in the subjects of study and the analyses used to evaluate study results.
