    Description / Table of Contents: Résumé Des métaux poreux et des céramiques sont implantés dans l'osin vivo et sont prélevés, après différents intervalles, pour étudier histologiquement la colonisation tissulaire. Les implants prélevés sont fixés avec les tissus environnants et inclus dans des epoxy-résines, de faible viscosité. Les échantillons sont coupés à l'aide d'une scie diamantée et fixés sur des lames pétrographiques, pour être ensuite amincis à environ 75 μm. Ils sont légèrement colorés au bleu de méthylène et à l'alizarine rouge S, qui donne un bon contraste entre tissus durs et mous et démontrent la présence d'os calcifié dans les implants poreux métalliques et céramiques.
    Abstract: Zusammenfassung Poröse Metall- und Keramikstücke wurden in vivo in Knochen implantiert und nach verschiedenen Intervallen entnommen, um histologisch zu untersuchen, wie weit sie ins Gewebe eingewachsen waren. Die entnommenen Implantate mit dem sie umgebenden Gewebe wurden fixiert, dehydriert und in ein niedrigvisköses Epoxy-Harz eingebettet. Die Proben wurden mit einer Diamantsäge in dicke Schnitte zerteilt, auf Steinscheiben zementiert und von Hand auf etwa 75 μm geschliffen. Sie wurden mit Methylenblau und Alizarin-Rot S schwach gefärbt; dies ergibt einen großen Kontrast zwischen Knochen und Weichgewebe und zeigt die Bildung von verkalktem Knochen innerhalb poröser Metall- und Keramik-Implantate deutlich.
    Notes: Abstract Porous metals and ceramics were implanted in bonein vivo and retrieved at intervals for histological evaluation of tissue ingrowth. Recovered implants with surrounding tissues were fixed, dehydrated and embedded in a low-viscosity epoxy resin embedding medium. The embedded samples were cut into thick sections with a diamond saw, cemented to petrographic slides, and hand-ground to approximately 75 μm. They were lightly stained with methylene blue and Alizarin Red S, which provided great contrast between the bone and soft tissues, and clearly demonstrated the formation of calcified bone within porous metal and ceramic implants.

    Taming B.C. Hydro: Site C and the implementation of the B.C. Utilities Commission Act (1988)

    Notes: Abstract Public policy making in resources management is greatly influenced by the institutional arrangements that arise out of the legal powers, administrative structures, and financial provisions of the decision system. In British Columbia, the institutional arrangements for energy planning in the province have been greatly altered by the passage of the Utilities Commission Act in 1980. This act redefines the policy implementation process for energy in British Columbia and provides for the regulation of the province's power utility, B.C. Hydro. This is the first time that the hitherto autonomous utility has been subject to regulation and the Utilities Commission Act represents a major reform in the institutional arrangements for energy planning in the province. The article evaluates the effectiveness of the 1980 B.C. Utilities Commission Act and assesses the impact of the legislation upon the institutional arrangements for energy planning in the province. Data for the article were derived from written sources and a series of personal interviews with key participants involved with energy planning in B.C. It is shown that the act represented a major departure in the management of energy resources in B.C. Moreover the implementation of the act's provisions, particularly in regard to B.C. Hydro, had a dramatic impact on the development of new energy projects in the province. It is suggested that while the political and economic climate during the period also favored restraint, the major influence on “taming” the utility was passage of the Utilities Commission Act. The article concludes by exploring the implications of policy changes that have occurred as a consequence of the act's impact on B.C. Hydro.
