Avec des taux de nitrates dépassant les seuils définis par la Directive européenne « », puis présence résidus pesticides utilisés activités agricoles du secteur, l’eau bassins d’alimentation captages l’Auxerrois fait l’objet préoccupations depuis une trentaine d’année. C’est ainsi qu’à fin années 1990, représentants pouvoirs publics ont choisi mettre en place démarche préventive passant un trav...

Les évolutions de la sociologie rurale en Roumanie ne permettent pas d’observer un simple face-à-face entre les promoteurs d’une recherche alignée sur des standards internationaux et défenseurs une science autochtone, ajustée aux réalités locales. positions prises position agents donnent progressivement forme à champ scientifique : certains ont participé échanges académiques sous le régime comm...

The improvement of the manufacturing productivity today is increasingly a result of cooperation between companies. Reflection on such industrial organization called “industrial architecture” aims at the development of a specific decision-making and control supports. The objective of our work is to propose a formalization of this cooperation by intending to coordinate the means used for consumer...

We introduce an algorithm to determine when a sorting operation, such as stack-sort or bubble-sort, outputs a given pattern. The algorithm provides a new proof of the description of West-2-stack-sortable permutations, that is permutations that are completely sorted when passed twice through a stack, in terms of patterns. We also solve the long-standing problem of describing West-3-stack-sortabl...

houchang golchiri, écrivain iranien et auteur du prince ehtejab, l’une des œuvres capitales de la littérature moderne persane, a rédigé en 1971 un roman intitulé christine et kid, inspiré largement du nouveau roman français et imité même, sur le plan thématique et structural, de la jalousie d’alain robbe-grillet. l’histoire du roman de golchiri se tisse autour de l’hyperthème de la jalousie, ma...

Haemogregarine infections in little skates, Raja erinacea, were assessed for a period of approximately 1 year. Prevalence of Haemogregarina delagei in little skates varied seasonally between 77 and 91%. Prevalence of leeches (Oxytonostoma typica) varied between 9 and 18%. One leech was removed from a little skate (from Passamaquoddy Bay, New Brunswick) heavily infected with H. delagei. Imprints...

This paper describes the Process Algebra Compiler (PAC), a front-end generator for process-algebra-based veriication tools. Given descriptions of a process algebra's concrete and abstract syntax and semantics as structural operational rules, the PAC produces syntactic routines and functions for computing the semantics of programs in the algebra. Using this tool greatly simpliies the task of ada...

In this paper new div-curl results are derived. For any open set Ω of RN , N 2, we study the limit of the product vn · wn where the sequences vn and wn are respectively bounded in Lp(Ω)N and Lq(Ω)N , while divvn and curlwn are compact in some Sobolev spaces, under the condition 1 1 p + 1 q 1 + 1 N . Our approach is based on a suitable decomposition of the functions vn and wn, combined with the ...
