In a study of Lunar and Mars settlement concepts, an analysis was made of fundamental design assumptions in five technical areas against a model list of occupational and environmental health concerns. The technical areas included the proposed science projects to be supported, habitat and construction issues, closed ecosystem issues, the "MMM" issues--mining, material-processing, and manufacturing, and the human elements of physiology, behavior and mission approach. Four major lessons were learned. First it is possible to relate public health concerns to complex technological development in a proactive design mode, which has the potential for long-term cost savings. Second, it became very apparent that prior to committing any nation or international group to spending the billions to start and complete a lunar settlement, over the next century, that a significantly different approach must be taken from those previously proposed, to solve the closed ecosystem and "MMM" problems. Third, it also appears that the health concerns and technology issues to be addressed for human exploration into space are fundamentally those to be solved for human habitation of the earth (as a closed ecosystem) in the 21st century. Finally, it is proposed that ecosystem design modeling must develop new tools, based on probabilistic models as a step up from closed circuit models. ^

Utilities have made strides in reducing air pollutant levels, but the proposed 1990 Clean Air Act Amendments call for even greater reductions and more stringent enforcement. Federal and state air enforcement agencies now encourage the use of negotiated settlements as a way to bring about compliance. This research examines the operation of such procedures in 19 case studies and a formal survey with the negotiators to account for the differences in the nature of the settlements and to identify the factors contributing to their perceived success. ^

Paul de Kruif is credited with being one of the first popular science writers for the general public. He received his Ph.D. from the University of Michigan in 1916 and worked at the Rockefeller Institute under Simon Flexner. After being fired in 1922 for publishing a scathing article on medical research, de Kruif caught the attention of Sinclair Lewis, who used his scientific background to write his Pulitzer Prize winning novel, Arrowsmith. In 1926, de Kruif published Microbe Hunters which recounted the exploits and discoveries of 14 renowned microbiologists from von Leeuwenhoek to Pasteur, Ross, Paul Ehrlich and Walter Reed. Microbe Hunters became a best seller, was translated into 18 languages, and formed the basis of two Hollywood movies, "Yellow Jack" and "The Magic Bullet." Generations of young readers were captivated by the vivid protrayal of these men and their discoveries.
