The nature of the rotational motion is not yet established but appears to involve two-fold reorientation through an angle a and the restriction in the motion involves either part

Based on the analysis we also showed that for a large class of models the annealed approximation does provide exact results for both magnetization and overlap order parameters;

J. Interactions between substitutional and orien- tational orders. The phase transitions in enantiomeric and racemic crystals of TMHP. A thermo- statistical approach of the two

Gaussian curvature (focal conic domains of the usual type) close to the phase boundary with the L~ sponge phase, and defects with positive Gaussian curvature (focal conic domains

This fact could be explained by assuming the formation of thick layers of PZT between the grain of the reactant pro ducts which probably hindered the mass-transport..If this is

These curves are modi- fied by aging in the way that a peak appears at the aging temperature (Fig. The formation of this peak goes ahead with the time constant of

Among the wide available PCMs, butyl stearate has interesting properties due to its phase change temperature and relatively high heat storage capacity; therefore, it

En respect avec la norme Z500, et dans le cadre du test des systèmes temporisés, nous avons choisi le modèle des automates temporisés avec durées d’actions les DATAs pour
