x a couple of series of reVlew lectures, each one through contributed talks and discussions. the outlet consultation used to be dedicated to reviewing the latest effects in regards to the choice of chemical abundances in quite inte resting gadgets delivering direct proof for stellar nucleosynthesis (like planetary nebulae, supernovae and supernova remnants). In consultation 2 fresh effects on a few suitable nuclear response charges were offered. consultation three grouped the contributions in regards to the quasi-static evolution of ordinary stars, its relevance for the nucleosynthesis of the varlOUS components and isotopes, and the comparability of the evolutionary versions with the observations. consultation four addressed the $64000 questions of determining the precursors of either variety I and sort II supernovae, and of deciding on the designated composition of the ejecta through explosive nucleosynthesis linked to those occasions. ultimately, consultation five was once dedicated to a presentation of modern calculations of the evolution of hypothetical pre-galactic very large gadgets (in cluding their strength position in pre-galactic nucleosynthesis), and to reviewing the growth that has been made in realizing the chemical evolution of galaxies. The dialogue in the course of and after talks used to be lively and contributed signi ficantly to the succes of the workshop. We regrett for now not having been capable of reporting it "in toto" within the court cases. however, we are hoping that what has been recorded should still supply to the reader at the least a part of the buzz now we have skilled through the ten days of the workshop.
