ITEM:1

TITLE: Dr. Richard M. Levy, Associate Professor of Urban Planning, Faculty of Environmental Design, University of Calgary
SUBJECT: #21 The Virtual Reconstruction of Phimai Temple
SYNOPSIS: A United Nations World Heritage Site, Phimai in Thailand is a walled complex of reconstructed temples, libraries and ancillary structures. It is considered one of the most important Khmer monuments in Thailand.  After the temple site was reconstructed and with the help of Alberta's unique program MACI (Multimedia Advanced Computing Infrastructure), Dr. Richard Levy of the University took on the job of creating a virtual or computer reconstruction of this historic temple site. The project required thousands of hours of computer drafting and rendering.  But it now provides a virtual tour for historians as well as the public, who can visit the site in virtual reality without damaging the fragile sandstone buildings. A video and animation of the Temple at Phimai produced by Richard Levy will be sown at the SIGGRAPH Conference in Los Angeles this summer.  Images from his work will be published in the June issue of Canadian Architect and his work will be exhibited in Edmonton June 22 to July 4.

ITEM:2

TITLE: Yash Kalra, Soil Chemist, Canadian Forest Service, Edmonton, Craig Mushens and Dr. John Post, University of Calgary, Dr. Walter Willms, Agriculture Canada
SUBJECT: #21 Finalists in the Research and Innovation Category, 2001 Emerald Awards for Environmental Excellence
SYNOPSIS: Yash Kalra was a finalist in the Research and Innovation Category at the 10th Annual Emerald Awards in Calgary this year.  His work centred on establishing international standards for testing soil pH. Soil pH is the most important factor in plant growth.  Yet the last time the Association of Official Analytical Chemists published any protocols for testing soil pH was in 1955.  Yash Kalra was determined to bring these standards up to date.  Beginning in 1992, he sent more than 4000 soil samples to soil testing labs around the world.  After analyzing the results and determining specific methodology for testing different soils, the new protocols developed by Yash were adopted by the AOAC and published in 1995 in "Official Methods of Analysis"

Dr. John Post, Professor in Biological Sciences, University of Calgary
Craig Mushens, Masters Student in Biological Sciences, University of Calgary

The Lower Kananaskis Lake Bull Trout Research, Management and Education Program of John Post and Craig Mushens was chosen as a finalist in the Research and Innovation category at the 10th annual Emerald Awards for Environmental Excellence in Calgary this year. A 1992 study by biologist Jim Stelfox showed bull trout were so depleted in the Lower Kananaskis Lake that only 60 adult fish could be found in the Lake.  "No harvest" regulations were imposed on the lake.  And Dr. John Post and Craig Mushens from the University of Calgary initiated a study to assess the effectiveness of the new regulations and to make management regulations. The bull trout population in the lake has since recovered to about 1300 adult fish.

Dr. Walter David Willms, Rangeland Ecologist, Agriculture Canada, Lethbridge

The winner of the 2001 Emerald Award for Environmental Excellence in the category of Research and Innovation.

Building on work started in the 1940's, Dr. Walter Willms studied the effects of cattle grazing on fescue grasslands and the mixed prairie with the intention of finding a way to preserve native prairie while allowing economic opportunities for the rancher. Walter found that unlike bison, which grazed in the winter, cattle are grazed in the summer, which is highly detrimental to the grasslands.  He also found that the amount of natural litter left on rangeland determined the conservation of water in the soil.  One thing he developed as a result of this research was a seasonal feeding and supplementation system which protects the native grasslands.
