Dr. Flynn, Department of Biochemistry, Queen's University, has contributed significantly in two areas of biochemical research. He was a participant in the pioneering work on the isolation, purification and characterization of the new peptide hormone cardionatrin. His laboratory determined the amino acid sequence, that is, the basic structure of this heart hormone. More recently, he has participated in the isolation of the kidney receptor for cardionatrin. He has also contributed in a major way to our understanding of the biochemistry of aldose reductases. His purifications and kinetic studies have led to an organized classification of these enzymes.

Gilles Fontaine, de I'Université de Montréal, se consacre à l'étude des étoiles de type naines blanches. L'étude de ces cadavres stellaires, leur autopsie en quelque sorte, représente un chapitre essentiel de l'astrophysique contemporaine, intéressant à la fois l'astronome et le physicien. Il ya quatre facettes des ses travaux actuels: mieux comprendre la nature des pulsations présentes dand certaines naines blanches; lqa d.termination de la composition chimique superficielle des naines blanches et la compréhension des variations observées; l'étude des étoiles sous-naines, génitrices d'une pantic des naines blanches; et l'exploration systématique de I'hémisphère sud pour y découvrir de nouvelles naines blanches et sous-naines.

Using a wide variety of light and electron microscopic techniques, Forer has challenged the assumption that chromosomes move during cell division by forces originating within the microtubules of the spindle fibres which connect chromosomes to the spindle poles. He has implicated the contractile protein, actin, as providing the force for chromosome movement, and is exploring the control of this movement. He is among the most influential leaders in this important field and is continuing to contribute actively to it.

Monsieur André Fortin, mycologue et pédologue de grand mérite, a consacré tous ses efforts depuis près de 20 ans à l'étude de la mycorhization chez les arbres et les arbustes. Les résultats remarquables de ses travaux sont en partie consignés dans une trentaine de publications scientifiques et de plus de 18 thèses par ses nombreux élèves. Ses recherches ont fourni des résultats étonnants qui ont donné lieu à des applications pratiques remarquables et très prometteuses. Membre de plusieurs commissions de recherches, membre actif et président de plusieurs sociétés scientifiques, organisateur de la cinquième conférence nord-américaine sur les mycorhizes (1981, à Québec), sa réputation a dépassé les frontières du Québec et du Canada.

The Alouette I satellite, launched in 1962, and still operating in 1972, is an enduring tribute to the engineering skill of Colin Franklin, who led the electrical engineering team on that satellite, and the three which followed it, Alouette II, ISIS-I and ISIS-II. All four satellites have performed much beyond expectations, and have given to Canada an international reputation for satellite design and engineering. Alouette I has operated longer than any other satellite in orbit, and has produced data on the ionosphere on which more than 300 papers have been published, by scientists from 9 countries.

URSULA M. FRANKLIN, Professor, Metallurgy and Materials Science and Director of Collegium Archaeometricum, University of Toronto, is an applied scientist who has truly bridged and cemented the disciplines of materials science, archeology, and anthropology through her outstanding and insightful scholarly work. From a foundation laid in her earlier researches on the crystaline micro-structure of alloys and melts, which pioneered the use of microradiography, she has delved into the science of ancient materials including the remarkable Chinese bronzes, discerning from artifacts the early techniques of metal-working and ceramic firing. She is a principal authority on archeometry, sought out worldwide by research collaborators. She has fully supported in her extensive work and writings her view that such artifacts are equivalent to literary sources, capable of describing culture but needing to be read and evaluated by a variety of techniques based on modern materials science, and she has accomplished this as few others have. By many Canadians she is recognized as an eminent scholar who is an eloquent spokesperson for social concerns about burgeoning technology, for a conserver society, and for international peace.

Dr. R. Allan Freeze, professor of geology at the University of British Columbia, is a leader in the field of mathematical modelling of groundwater flow systems and associated problems of stream flow generation, transient saturated and unsaturated flows, and the statistical effects of various parameters of the permeable media as affecting this flow. Though his major contributions have been of a theoretical nature, his work on mathematical predictions of the subsidence of Venice is clearly applied science. As a successful teacher in the field of engineering hydraulogy and as an editor of the journal "Ground Water Research", he effectively straddles fields of geology, civil engineering, and applied mathematics.

John Friedlander is the leading Canadian mathematician in analytic and elementary number theory. He has a well established international reputation for his work in sieve methods, exponential sums and the distribution of prime numbers. He has consistently been an invited speaker in recent years to the top international conferences in the subject.

Dr. Friesen is an internationally renowned Canadian endocrinologist whose major research contributions relate to lactogenic and growth hormones from the placenta and pituitary. Subsequent to his identification of human prolactin, and the development of radioimmuno-assays for it, he has been a central figure in characterizing the synthesis and secretion of prolactin in health and disease as well as studying target tissue receptors for these hormones. He has, and continues to carry on an investigative career of singular productivity, systematically elucidating the biochemistry, physiology and pathophysiology of lactogenic hormones. Dr. Friesen continues to play a pivotal role in ongoing national studies of the therapeutic use of human growth hormone and in establishing the therapeutic efficacy of agents which control prolactin secretion. One of these now has been accepted world wide to be effective in decreasing elevated prolactin levels to normal, thereby correcting impaired fertility experienced by these patients. He has published over 190 scientific articles.

Dr. Barrie Frost, a Full Professor in Psychology and Associate Professor of Physiology at Queen's University has an international reputation of the highest order for his work on vision research and the aid of the profoundly deaf. His research has been well supported by national granting agencies and has led to the publication of numerous scientific papers and to invited presentations at many national and international conferences. He has held a number of important offices in the national research granting bodies and is currently the Group Chairman of Life Sciences in the National Sciences & Engineering Research Council. Recently he was appointed by the minister of Health as a National Health Research Scholar.
