The Chemical Composition of the Observable Universe, proportion of the chemical elements classified a century ago by the Russian chemist Mendeleev. Before displaying the main trends of this chemical composition, let us briefly recall the main techniques which are used by the astrophysicists to determine this composition.

Thermonuclear Reactions and Nuclear Reactions in Stellar Interiors,this book we assume that the target nucleus is the heavier nucleus. The effects we are discussing here are symmetrical and remain the same if the target is the lighter one. When the final products of the nuclear interaction are identical to the initial ones, it is called ‘scattering’. The scattering

At the beginning of this monograph, the evolution of the matter which constitutes the celestial bodies such as planets, stars and galaxies was briefly recalled. During this evolution, which lasted about 10. yr, the nucleosynthesis has modifi

An example for the new paradigm of process chain development is given: the decreased process chain for the production of gears for the automotive industry. Mater
