A case study of investment in agricultural sustainability: adoption and policy issues for nitrogen pollution control in the Chesapeake Bay drainage
… an economic and physical model, seven production systems and nitrogen management strategies are compared in terms of input use, profitability, and nitrogen loss potential. Results suggest that several of the production systems will reduce residual nitrogen without reducing profits. However, it is …

Examining the feasibility of a novel ground-storage cooling system
… moisture onto surfaces cooled by cold water. The systems currently used to provide the cold water have limited efficiencies, so alternative systems must be sought in order to achieve reductions in building energy use and to reduce the rate of climate change. This research examines the feasibility …
