Many of Alabama's rivers and streams do not meet the Clean Water Act's "swimmable" goal due to fecal contamination. Catoma Creek in Montgomery County has been included on Alabama's Section 303(d) List due to elevated numbers of fecal coliform bacteria and organic enrichment. Both urban and agricultural land uses exist in the watershed. The objectives of this research were to construct a library...

This study examined radiocesium (137Cs) levels in fish from the vicinity of the Department of Energy's Savannah River Site (SRS), a former nuclear weapons production facility in South Carolina. Fish from the Savannah River were sampled above (upstream), along, and below (downstream) the SRS, and from Steel Creek, a tributary that runs through the SRS. There was some off-site contamination of 13...

The cycling of dissolved inorganic carbon (DIC) and the role of tidal marshes in estuarine DIC dynamics were studied in a Virginia tidal freshwater marsh and adjacent estuary. DIC was measured over diurnal cycles in different seasons in a marsh tidal creek and at the junction of the creek with the adjacent Pamunkey River. In the creek, DIC concentrations around high tide were controlled by the ...

‘Cedar Creek’ (Reg. no. CV-290, PI 700113) switchgrass (Panicum virgatum L.) was selected for increased winter survivorship three cycles, using surviving plants from ‘Kanlow’. The first two cycles were conducted at multiple locations in Wisconsin, and the third cycle Cedar Creek Ecosystem Science Reserve, East Bethel, MN. All seed production increases by either Illinois State University or of I...

This work examines how automatic generation of general domain knowledge from text can contribute to the knowledge intensive Case-Based Reasoning (CBR) system, Creek. This will be done by combining Creek with the ontology extraction tool CORPORUM to improve Creek’s ability to retrieve text. The ontology extraction tool is part of an architectural framework that is described. The framework descri...
