Multiplicity distributions in 24Mg-emulsion collisions at 4.5 A GeV/c.

The experimental results of target multiplicity distributions in 24Mg emulsion collisions at 4.5 A GeV/c are reported. The multiplicity distributions of target fragments, the correlations between the multiplicity distributions and the projectile fragments, as well as the correlations between the black and gray fragments are given. A comparison between theory and experiment among24Mg and 16O at various energies...

Prediction and measurement of the elastic modulus of the RCC: Case of the low cement proportioning

The Roller Compacted Concrete (RCC), which is presented as an evolutionary technology for a large diversity of applications (Dams, roads...), is considered, like conventional concretes and other construction materials, as an elastic material. The RCC in pavement supports many stresses which involve deformations and reciprocally. The knowledge of the relation between strength and deformation, for a material such as the...
