Z. S. Basinski has long received international recognition among metal physicists for his many contributions to the understanding of processes involved in the deformation of metals. His attribution of work-hardening to the interaction of glide and forest dislocations is now generally accepted after 20 years of spirited controversy. Other problems on which he has made major contributions include: explaining deviations from the Cottrell-Stokes law, puzzling aspects in the deformation of b.c. cubic metals, solution hardening of f.c. cubic metals, and processes involved in fatigue failure. His deep understanding of many aspects of metal physics is acknowledged.

David Bates is distinguished not only as a teacher and physician but especially an investigator of human respiratory function. His method for a closed circuit mixing index developed in 1948 is still widely used. He perfected the carbon monoxide method for measuring the effects of disease of the lung and devised the powerful xenon 133 technique for assessing pulmonary ventilation and blood-flow, being the first to put these on a quantitative basis. He was the first to measure the effects of ozone, and its hazards in high flying aircraft. He is recognized in Amerlca and Europe as a leading authority on lung function in health and disease. He has recently initiated epidemiological studies of the effect of air pollution on health which have been influential in terms of public policy.

An established botanist, with a book on "Tamarix" published in Israel, Dr. Baum reached Canada Dec. 1966 to study "Avena" and related grasses. A succession of papers on taxonomy, new characters and data-handling methods soon appeared; and books on oat registers (1969, 1973) to trace pedigrees of oat cultivars. His monograph on oats appeared in 1977, and, like the registers, met world acclaim. Dr. Baum, with 89 publications, is now revising barleys and other grasses. Recipient of the U.S.D.A. Merit Award and the Lawson Medal, he is in demand as a speaker. A recent, warmly received symposium address largely harmonizes taximetric and genomic grass classifications.

Dr. Margaret Becklake is a chest physician and respiratory physiologist who has made major contributions to new knowledge in the field of occupational lung disease, and in the application of lung function tests to epidemiological research. She is unquestionably the world authority on disordered lung function in asbestosis. Her international renown is recognized by her chapters on occupational lung disease in the two definitive textbooks of respiratory medicine, the leading textbook of Internal Medicine (Cecil and Loeb), the APS Handbooks of Physiology and as Chaiman or Summarizer of several international symposia on occupational health.

GRAHAM BELL has worked on several basic issues in ecology and evolution. He helped to develop the modern evolutionary theory of aging, and performed experimental tests of its premises and predictions. His book on the evolution of sex was among the first to argue that the function of sex is to produce recombinant progeny which are resistant to prevailing diseases, and has been followed up by theoretical and comparative investigations of this idea. To pursue these and other issues in the laboratory, he has established "Chlamydomonas" as a model system in which evolutionary mechanisms can be studied in detail under controlled conditions. At the same time, field experiments have linked the laboratory system with the response of native plants to environmental variability in undisturbed primeval forest.

Dr. Bernstein is nominated for his research contributions in three major areas of science, cell biology, retrovirology and molecular biology. His work has provided seminal information on the molecular structure and function of the retroviruses and he has developed and used new constructs of such viruses as transfection vehicles to examine problems in stem cell differentiation and gene therapy. Dr. Bernstein has also played a major role in an advisory capacity in Canada and elsewhere in the cancer field.

James MacDonald Richardson Beveridge came to Canada from Scotland in 1927 and studied successively at Acadia University, the University of Toronto and the University of Western Ontario. He held teaching and research posts at the University of Toronto, the University of Western Ontario and the Pacific Fisheries Experimental Station, Vancouver. In 1950, he was appointed Craine Professor of Biochemistry at Queen's University. His research interests are primarily in the field of nutrition and lipid metabolism. He is recognised as an authority in the relation of liver necrosis to dietary deficiency. His recent experiments in the dietary control of the level of plasma cholesterol, in which approximately 700 undergraduate students and members of the Faculty have participated, place him in the forefront of those investigators whose interest is in the relation of atherosclerosis to diet.

Dr. Bewley is one of the leading plant physiologists in Canada and is internationally recognized for his research on drought-resistance and on seed germination. His work is not only prolific, but also searching and innovative, and he is a highly sought-after speaker and author. His excellence has been recognized by many awards, including The C. D. Nelson Award of the Canadian Society of Plant Physiologists and an E. W. R. Steacie Memorial Fellowship, the Gold Medal of the Canadian Society of Plant Physiologists, and the Distinguished Scientist Award of the Canadian Council of University Biology Chairs. (1943; Professor of Biology, University of Calgary.) Dr. Bewley's major contributions to research have been in the areas of desiccation tolerance and seed biology, although he has also published significant papers on other topics. His pioneering work in elucidating the cellular mechanisms involved in conferring desiccation tolerance to lower plants has been widely acclaimed. His studies on seeds encompass several aspects of development and germination, but particular recognition has been given to his work on control of mobilization of reserves in lettuce - the first work of this kind in dicot seeds. He is the co-author of four books on Seed Biology, which have received international acclaim.

John Bienenstock has made two major conceptual contributions to understanding the immune response at the mucosa. Bienenstock demonstrated a common mucosal immune system in which cells primed at one mucosal site circulate to another to provide protection, and introduced the universally accepted concept of mucosal associated lymphoid tissue (MALT). He also described the integral association of nerves and mast cells in mucosal tissue and postulated neuroendocrine regulation of inflammation and immunity. These conceptual advances have been accepted and refined by many others throughout the world and demonstrate the major leadership role played by Bienenstock in the field of immunology.

By reason of achievements and reputation, Dr. Billinton is regarded as being amongst the top international experts in the area of electric power systems reliability. His fundamental and pioneering studies in this area have materially contributed to power systems reliability over the past decade. These studies have been published in some 600 papers and eight books. His first book, published in 1970 is internationally regarded as fundamental to the area. In his capacity as one of the leading experts on the adaption of reliability theory to the assessment of the reliability of electric power systems he has been a frequent principal speaker at seminars and courses on both sides of the Atlantic.
