Like a discovery game that requires players to earn the right to take on new challenges, Immune Attack compels its players to learn the rules of the immune system before it reveals deeper biological insight.
This paper describes an ongoing project to demonstrate an affordable, safe, and energy-efficient housing technology based on expanded polystyrene (EPS) panels with a cementitious coating. The concepts being described are (1) EPS panels embedded with galvanized steel trusses, steel mesh welded or clipped to the protruding points of the trusses and finished with a coating of cement plaster; (2) fiber-reinforced cement board panels and a core of EPS, glued together with high-strength adhesive, dried under high pressure, and connected with cellulose fiber cement board splines; and (3) EPS panels coated with a fiber-reinforced composite. The scope of this project is to model energy flows, analyze costs, simulate seismic forces, test against environmental conditions, and build pilot houses initially in California, Texas and Afghanistan. Results from air quality and energy flow analyses, preliminary cost modeling, structural calculations, and fire testing are reported. The performance goals address seismic safety; energy efficiency in extreme temperatures to reduce fuel use and indoor air quality hazards; affordability and simplicity of construction, as well as ease of expansion for future development; local employment opportunities and small-scale capital investments; and finally, cultural acceptance through education and adaptation to traditional architecture.
Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302.

The quality of the U.S. workforce is critical for a competitive economy in today’s fast-paced, tightly connected global economy. Given current trends the quality of the U.S. workforce, measured in educational attainment and knowledge of key concepts in science, mathematics, and engineering will actually decline in coming years. Conventional methods will simply not be adequate to the enormous task of improving this situation. The technology and management tools that have been used so successfully to increase both quality and productivity in other service enterprises can play a vital role in improving science and mathematics education and training.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
