In January 1996, Cogito, the U.S. challenger, defeated the Australian defender, Yellow Pages Edge, by the score of 4–0 in the 22nd running of the International Catamaran Challenge Trophy. This brought the trophy, better known as the Little America's Cup, back to the United States after an eleven-year stay in Australia. The Cogito project was three years in length and encompassed the design/construction phase, initial sailing and tuning at her home, the Bristol Yacht Club in Bristol, Rhode Island, and the final training and competition at the race venue, McCrae Yacht Club on Port Philip Bay south of Melbourne, Australia. This paper will cover all phases of the project from the design through the racing.

The Individual

ABSTRACTThe Chinese government has conducted remedial action for radioactive waste rock piles since 1990. The radioactive waste rocks produced in the course of geological exploration of uranium deposits are widely distributed over several hundreds of locations in more than 20 provinces in China.The following remedial actions for radioactive waste rock piles have been undertaken in China:1. Protecting dams for stabilizing the piles have been built. A total length of about 50,000 m of these dams has been completed.2. Soil layers have been emplaced on the radioactive waste rock piles. The focus of the action is to eliminate the radiation harmful to public health. A total area of 750,000 square meters of soil ahs been placed on the piles in China.3. Radioactive waste rock piles have been vegetated. Aesthetic shaping of the landscape in the exploratory district of the uranium deposits is our expectant goal. A total area of about 560,000 square meters of vegetation has been placed on the soil covering the piles.Through these remedial actions, the environmental situation has been extensively improved in the remedial districts. The individual annual effective dose equivalent is less than 1 Sv/a. The radon emission rate is less than 20 pCi/m2.s. The gamma ray external exposure rate has been greatly reduced.
