LA DISTRIBUTION SELECTIVE, LA FRANCHISE ET LA CONCESSION SONT DES CONTRATS DE DISTRIBUTION QUI POSTULENT, TOUS, UNE SELECTION ET UN CONTROLE DES DISTRIBUTEURS, AINSI QUE LA MISE EN OEUVRE DE MOYENS DE PROTECTION A RENCONTRE DES REVENDEURS EXTERIEURS AU RESEAU. A COTE DE CES ELEMENTS GENERIQUES, EXISTENT DES ELEMENTS QUI SONT REPUTES SPECIFIQUES AUX ACCORDS DE DISTRIBUTION. LA DISTRIBUTION SELECTIVE NE COMPORTE AUCUN ELEMENT SPECIFIQUE, C'EST UN SIMPLE ACCORD DE COOPERATION PAR LEQUEL UN PRODUCTEUR IMPOSE A DES DISTRIBUTEURS SELECTIONNES UN CERTAIN NOMBRE D'EXIGENCES, QUI PEUVENT AUSSI BIEN ETRE PREVUES DANS LES AUTRES CONTRATS. EN REVANCHE, LA FRANCHISE EST SUBORDONNEE A LA MISE A DISPOSITION, PAR LE FRANCHISEUR AU FRANCHISE, D'UN SAVOIR-FAIRE, D'UNE ASSISTANCE CONTINUE, ET DE SIGNES DE RALLIEMENT DE LA CLIENTELE. LA MISE A DISPOSITION DE TELS ELEMENTS PEUT SE RENCONTRER DANS LES AUTRES SYSTEMES, ELLE N'EST DONC PAS DISTINCTIVE DE LA FRANCHISE. SIMPLEMENT, CETTE MISE A DISPOSITION EST QUALIFIANTE DE LA FRANCHISE, ET DE LA FRANCHISE UNIQUEMENT. ENFIN, LA CONCESSION EST LE CONTRAT PAR LEQUEL UNE PARTIE CONFIE A L'AUTRE L'EXCLUSIVITE DE REVENTE DE SES PRODUITS SUR UN TERRITOIRE PRECISEMENT DEFINI. CETTE EXCLUSIVITE TERRITORIALE PEUT EXISTER DANS LES AUTRES SYSTEMES, ELLE N'EST DONC PAS DISTINCTIVE DE LA CONCESSION. SIMPLEMENT, ELLE EST QUALIFIANTE DE LA CONCESSION ET DE LA CONCESSION UNIQUEMENT. AU DELA DE CES RESSEMBLANCES ET DE CES DISSEMBLANCES, IL APPARAIT QUE L'EVOLUTION DU DROIT VA DANS LE SENS D'UNE APPRECIATION CONVERGENTE DES SYSTEMES DE DISTRIBUTION, PLUTOT QUE VERSL'EXALTATION DE LEURS DIFFERENCES.

Biofilms -- Science and Technology covers the main topics of biofilm formation and activity, from basic science to applied aspects in engineering and medicine. The book presents a masterly discussion of microbial adhesion, the metabolism of microorganisms in biofilms, modelling of mass transfer and biological reaction within biofilms, as well as the behaviour of these microbial communities in industry (waste water treatment, heat exchanger biofouling, membranes, food processing) and in medicine (teeth, implants, prosthetic devices). Laboratory techniques and industrial monitoring methods are also presented. The book is directed at readers at the postgraduate level and is organised as a textbook, containing 11 chapters, a glossary, and a detailed subject index.

Assesses the impact of dynamic water quality conditions in the distribution system on the inactivation of microorganisms in bulk water. Addresses questions about the usefulness of maintaining a secondary residual and the target level to be maintained. Bridges research related to distribution system water quality with that of microbial inactivation.

Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
