Nanofiltration Membrane Pilot Studies For Disinfection By-Product Control, Eric J. Lynne
Nanofiltration Membrane Pilot Studies For Disinfection By-Product Control, Eric J. Lynne
Electronic Theses and Dissertations
Watertown, South Dakota currently uses conventional softening to treat ground water to remove hardness, iron and manganese, and natural organic matter. The distribution system has experienced elevated concentrations of disinfection by-products, which will require additional treatment to comply with future limits set by the Stage 2 Disinfectant/Disinfection By-Products Rule. A nanofiltration membrane system has been proposed to remove additional natural organic matter from the softened water. Removing the natural organic material disinfection by-product precursors should reduce the concentration of disinfection by-products. The use of nanofiltration membranes has been previously documented to reject total organic carbon, while allowing desirable levels of …

Purpose: To determine wheather ot not the nutritional supplement PreRace containing L-Taurine, Citrulline Malate, Quercetin, DiMethyl Amino Ethanol, Caffeine, Metabromine, Catechin, and Malic acid will improve performance in an indoor 40 Kilometer cycling time trial.
Methods: Seven male cyclists ages 21-58 participated in a placebo-controlled investigation which consisted of two trials in which they consumed either the supplement PreRace or aloe vera juice. In each of the trials the placebo or supplement was mixed with a sports beverage. Subjects performed a 40 kilometer time trial and measurements of oxygen consumption and lactate were taken every 15 minutes as well as …
Reintroduction Of Bison (Bison Bison) On Reservations In South Dakota: Four Case Studies, Trudy M. Ecoffey
Reintroduction Of Bison (Bison Bison) On Reservations In South Dakota: Four Case Studies, Trudy M. Ecoffey
Electronic Theses and Dissertations
This research explored and documented issues of sustainability associated with the reintroduction of bison in four different bison herds on Reservations in South Dakota. The four herds were managed by: a tribal family cooperative, an individual tribal member, a tribal university and a tribal fish and wildlife agency. The objectives were to identify management practices associated with the sustainability of bison introduction by American Indians; to explore the role of American Indian culture in the management of bison for sustainability; and to investigate rangeland criteria that could be used to measure sustainability of bison reintroduced by American Indians. This project …
