The global objective of the recently completed Phase 1 of the West Virginia Diesel Study, at West Virginia University, was to evaluate mass emission rates of exhaust emissions from diesel powered equipment specified by the West Virginia Diesel Equipment Commission. The experimental data generated in this study has been utilized by the West Virginia Diesel Equipment Commission to promulgate initial rules, requirements and standards governing the operation of diesel equipment in underground coal mines.

A wide range of research topics were supported under this grant. These included: (1) complex space time singularities in nonlinear differential equations; (2) singularities in magneto-hydrodynamics; (3) the dynamics of knots and curves; and (4) the structure and dynamics of foams and grain boundaries. A brief summary of results achieved in each of these four areas is given below along with the associated publications acknowledging DOE support.

The once abundant stocks of Pacific lamprey (Lampetra tridentata) above Bonneville Dam are currently depressed (Close et al. 1995). It is likely that many of the same factors that led to the decline of wild stocks of Columbia River Pacific salmon and steelhead have impacted Pacific lamprey populations as well. The Pacific Lamprey Research and Restoration Project, funded by Bonneville Power Administration, is a cooperative effort between the Confederated Tribes of the Umatilla Indian Reservation, the Columbia River Inter-Tribal Fish Commission, and Oregon State University with the goal to increase Pacific lamprey stocks above Bonneville Dam.
