The preliminary re- sult on small angle boundaries showed that the main spectrum position was near that of solid solu- tion 'lgmsn and the line width was smaller than that

Neverthe- less, no model has yet successfully taken into account some important parameters such as the grain size, the grain shape and the mechanisms of

The dark line shows the data, the green line shows the continuum with a 3σ absorption line, and the red line shows the continuum with the line detected in Chandra data.

Voici un bref résumé pour bien comprendre le système des prédalles, avec le béton de deuxième phase et les aspects divers qui interviennent dans la capacité portante. En

Simulate the mechanical behavior of a material including severals interlocked grain periods. 

Reversely, at a larger scale, interlocked grain was positively related to wood tenacity, with a strong relationship between grain index and fracture energy.. Therefore, one
