After his career at DSIR, Gordon joined the Pulp and Paper Research Institute of Canada (Paprican) in September 1992 to carry out research into the bleaching of mechanical pulps. In recognition of his scientific achievements, he was elected a principal scientist (Paprican s highest scientific ranking) by his peers. He was later appointed executive director of the Canadian Mechanical Pulps Network of Centres of Excellence, a nationwide research association dedicated to enhancing the properties and value of mechanical pulps. In 1996 it included researchers from 15 universities, the National... 

Section on university-industry cooperation discusses three model relationships the Pulp and Paper Research Institute of Canada and McGill University, the Center for Cold Ocean Resources Engineering and Memorial University in St. John s, and the research brokering functions of the Industrial Research Institutes, and the Centres for Advanced Technology—both created by the Federal Department of Industry, Trade, and Commerce. Additional programs discussed ... 

We wish to express our profound thanks to Dr. J.-F. Revol of the Pulp and Paper Research Institute of Canada for his interest, discussions, and his willingness to characterize the lateral dimensions of crystallites in certain of the algal cellulose preparations. 

The orientation of particles in flow is of particular interest to microrheology. To predict the macroscopic rheological properties of a multiphase system, a detailed description of each phase behavior is required. In this field, contributions from the Pulp and Paper Research Institute of Canada by Mason et al. and later by van de Ven and his coauthors are particularly valuable. The earlier results were summarized by Goldsmith and Mason (1967), the latter by Van de Ven (1989). The microrheology has been particularly well developed for infinitely dilute systems in Newtonian matrix - either solid particles or liquid drops. In the present part, only the former system will be summarized. More extensive discussion of microrheology of the liquid-liquid systems will be presented later, while considering the rheological behavior of polymer blends.
