Discordance gradient-surface dans le rétrécissement mitral: le gradient moyen transmitral est-il un critère de sévérité ou un indice de tolérance du rétrécissement mitral serré?

Résumé Le rétrécissement mitral (RM) rhumatismal demeure une valvulopathie fréquente dans les pays en voie de développement. Cependant, les pays industrialisés ont vu l'émergence ces dernières années de nouvelles étiologies de RM; notamment l'origine médicamenteuse et/ou toxique responsable de valvulopathies restrictives aussi bien sténosantes que régurgitantes. Pour cette raison, l'évaluation ...

Le livre est tout le problème

The search into new ways of writing is confronted with certain obstacles, the foremost of which is that of the book and its conventions inherited from 536 years of existence. Yet, literature is by in large independent of the particular medium that is the book, as reminds us the age-old oral tradition or the contemporary research of the Oulipo. The incursion of the computer into literature has t...

Un Principe de Résolution en Logique Modale

— The applications of modal logic are connected with programming reasoning and for this reason we are interested in developping theorem proving System for it. A resolution-style theorem proving System for modal logic is presented. The two version of Herbrand property are proved. The completeness of the System is given. Nous présentons dans cet article une formalisation des modalités de re parfa...

Sur le Monoide Syntactique de L Lorsque L est un Langage Fini

We prove that for every finite monoid M , there exists a finite language L such that M divides the syntactic monoid of L∗. Moreover, one can choose for L a full finite prefix code. The same result for finite group has already been proved by Schützenberger. This result is crucial in the proof of the J.-F. Perrot’s theorem that the only variety closed under star operation is the variety of all ra...
