Reducing Equifinality Using Isotopes In A Process-Based Stream Nitrogen Model Highlights The Flux Of Algal Nitrogen From Agricultural Streams, William I. Ford, James F. Fox, Erik Pollock

The fate of bioavailable nitrogen species transported through agricultural landscapes remains highly uncertain given complexities of measuring fluxes impacting the fluvial N cycle. We present and test a new numerical model named Technology for Removable Annual Nitrogen in Streams For Ecosystem Restoration (TRANSFER), which aims to reduce model uncertainty due to erroneous parameterization, i.e., equifinality, in stream nitrogen cycle assessment and quantify the significance of transient and permanent removal pathways. TRANSFER couples nitrogen elemental and stable isotope mass‐balance equations with existing hydrologic, hydraulic, sediment transport, algal biomass, and sediment organic …
Circling The Drain: Regulating Nutrient Pollution From Agricultural Sources, William Gutermuth
Circling The Drain: Regulating Nutrient Pollution From Agricultural Sources, William Gutermuth
Journal of Law and Health
The 2014 Toledo, Ohio tap water ban has, at least temporarily, put a spotlight on United States water supplies. Consequently, many Americans have begun to take a closer look at the quality of the fresh water bodies being used to supply tap water to their homes. Therefore, this Note analyzes the problems currently threatening the lakes, rivers, and other surface waters that are the source of fresh drinking water for huge populations in the United States. Part II examines the problem of nutrient pollution and explains the harmful effects it has on human health. Part III provides an overview of …
Rediscovery Of The Microtubule System In Chlamydomonas, Yi Liu
Rediscovery Of The Microtubule System In Chlamydomonas, Yi Liu
Dissertations (1934 -)
Extensive studies have revealed the complex mechanisms underlying the roles of the microtubule system in fundamental cellular processes, the severe consequences in development and health resulted from its anomaly, and the irreplaceable therapeutic agents that perturbs this vital yet inherently unstable cytoskeletal system. Most of the concepts derived from a handful of model organisms become dogma of the field despite contrary observations. By overcoming a major limitation of biflagellate green alga Chlamydomonas - the intense autofluorescence common to photosynthetic cells - this dissertation discovered new phenomena of the microtubule system and conceived an invention. The microtubule system of the green …
Evaluation Of Flocculation, Sedimentation, And Filtration For Dewatering Of Scenedesmus Algae, Nicholas A. Rhea, Jack Groppo, Czarena Crofcheck

Algae can be used as a feedstock for agricultural fertilizers, livestock and poultry feeds, anaerobic digestion, and biofuel production. For each end product, the requirements for moisture content (or solids content) vary, such that a desirable water removal strategy needs to be adaptable to varying levels of water removal. Flocculation, sedimentation, and filtration were evaluated as possible strategies for thickening and dewatering of algae. The goal of this study was to validate that algae cells treated by such means could be processed by vacuum belt filters and to determine the conditions under which the solids content could be increased to …
