2014 The use of the Hall-Petch relation in texture simulations with the Taylor-Bishop-Hill model is proposed as a mean to take into account grain shape effect. The results are compared with those obtained with the usual and relaxed constraint Taylor model for a simple texture and the consequences for the anisotropy coefficient are investigated. J. Physique Lett. 46 (1985) L-1109 L-1113 1 er DEC...

We introduce a normative model of the optimal education policy at the macro level allowing for heterogeneity of the workforce with respect to its age and qualification skills. Within this framework we study the optimal education rate in the context of changes in the labor demand (as represented by the elasticity of substitution across ages and qualification) and labor supply (as represented by ...

Abstract Aim To understand whether core surgical trainees (CSTs) adhere to nationally issued guidance on health behaviours (government, NHS) and poor are related the demands of being a CST. Method An anonymised electronic questionnaire addressing five behaviour domains (exercise, diet, smoking, alcohol, sleep) stress was distributed all CSTs within one UK deanery. Results 29 (29%) responded. 17...

The kinetic of the enzyme production of Streptomyces rimosus, a producer of exoproteases was investigated in conditions of nitrogen limitation.The maxima of fibrinolytic and caseinolytic activities by Streptomyces rimosus were reached at 84 h, respectively 96 h. Values of activities were increased 5-fold with those on initial medium. The ultrastructure changes were followed. In the earlier hour...
