Quantifying The Source And Pathway Of Dissolved Reactive Phosphate In Karst Drainage Of The Inner-Bluegrass, Cory Radcliff
Quantifying The Source And Pathway Of Dissolved Reactive Phosphate In Karst Drainage Of The Inner-Bluegrass, Cory Radcliff
Theses and Dissertations--Biosystems and Agricultural Engineering
In the Midwestern U.S. seasonal hypoxia experienced in the Gulf of Mexico and harmful algal blooms in inland freshwater ponds, lakes, and rivers are partly fueled by dissolved orthophosphate loadings from disturbed landscapes. Efforts to reduce dissolved reactive phosphate (DRP) loadings have had varying levels of success and have led to insufficient water quality improvements. Inefficiencies in conservation strategies can stem from poor understanding of phosphate source and flow pathway dynamics. This study focused on monitoring sources and flow pathways of dissolved reactive P in a karst agroecosystem with phosphatic limestone. We collected event water samples at the Camden Creek …
Characterization And Upgrade Of Endocarp Biomass Derived Lignin To Value Added Products, Makua Vin-Nnajiofor
Characterization And Upgrade Of Endocarp Biomass Derived Lignin To Value Added Products, Makua Vin-Nnajiofor
Theses and Dissertations--Biosystems and Agricultural Engineering
Lignin is an abundant biopolymer and a promising source of feedstock for high-value chemicals and energy materials, however, application methods of lignin into valuable products is yet to be fully explored. This study explores the valorization of lignin derived from lignin-rich endocarp biomass through the development of lignin-derived electrode materials. The chemical composition and cellular structure of the endocarps were characterized using HPLC and scanning electron microscopy (SEM) imaging. Mechanical properties of walnut and peach endocarps and preprocessing requirements were investigated using nanoindentation and specific energy consumption during grinding. Next, lignin was extracted from endocarps using deep eutectic solvent and …
Extraction Of Micro- And Nano-Plastic Particles From Water Using Hydrophobic Natural Deep Eutectic Solvents, Jameson R. Hunter
Extraction Of Micro- And Nano-Plastic Particles From Water Using Hydrophobic Natural Deep Eutectic Solvents, Jameson R. Hunter
Theses and Dissertations--Biosystems and Agricultural Engineering
The production of plastic and the amount of waste plastic that enters the environment increases every year. Synthetic polymers will gradually break down into particles on the micro- and nano-scale. The micro- and nano-plastics pose a significant ecological harm by transporting toxic chemicals and causing inflammation and cellular damage when ingested. Two common plastics are polyethylene terephthalate (PET) and Polystyrene (PS), and a newer bioplastic polylactic acid (PLA) that has become a popular alternative. Deep eutectic solvents are a recently discovered solvent composed of a hydrogen bond donor and hydrogen bond acceptor and have been proposed as a cheaper alternative …
Impact Of Preferential Flow, Source Water Connectivity, And Agricultural Management Practices On Sediment And Particulate Phosphorus Dynamics In Midwestern Tile-Drained Landscapes, Saeid Nazari
Theses and Dissertations--Biosystems and Agricultural Engineering
Tile drainage is recognized as a significant transporter of sediment and particulate phosphorus (PP) in the Midwestern U.S., leading to proliferation of Harmful Algal Blooms (HABs). Numerous studies have focused on Dissolved Reactive Phosphorus (DRP) and Nitrogen (N) flux dynamics in tile-drained landscapes; however, the impact of preferential flow and agricultural management practices on fate and transport of sediment and PP has remained poorly understood. The overarching objective of this study was to improve understanding of sediment P delivery in tile-drained landscapes. This dissertation focuses on four studies. In the first study, forms and flow pathway dynamics of total phosphorus …
Modeling Energy Flows In Floating In-Pond Raceways Utilizing Solar Power Back-Up, Bo Smith
Modeling Energy Flows In Floating In-Pond Raceways Utilizing Solar Power Back-Up, Bo Smith
Theses and Dissertations--Biosystems and Agricultural Engineering
The In-pond Raceway (IPR) is a novel option for production aquaculture, depending on water moving devices to provide constant flow. Device failure may result in catastrophic fish loss, requiring power backup systems to mitigate risk in case of power outages. Because these systems must be dependable and many suitable locations are remote, off-grid solar photovoltaic (PV) systems with battery storage have been considered since they eliminate need for utility power. Such systems can be hard to size and expensive. This study modeled system requirements using an energy balance to determine whether systems could withstand varying loads based on climatological conditions. …

Analysis Of Modern Barn Design, Gunther Soehnlen
Analysis Of Modern Barn Design, Gunther Soehnlen
Williams Honors College, Honors Research Projects
The agriculture industry is always changing. Barn structures are one of the most important aspects of the agriculture industry. As the agriculture industry changes, so does the design and construction of barns. There are many types of barns, but over the last 300 years four of the most prevalent types have been the Bank Barn, Open Span Truss Barn, Hoop Barn, and Transverse Frame Barn. The Bank Barn and Transverse Frame Barn have been popularly built for over 200 years. The Hoop Barn and the Open Span Truss Barn have been recently introduced to the industry, becoming popular within the …
Biomass-Derived Electrode Materials And Sustainable Processes For Supercapacitors, Katelyn M. Shell
Biomass-Derived Electrode Materials And Sustainable Processes For Supercapacitors, Katelyn M. Shell
Theses and Dissertations
Biomass is one of the most abundant natural resources and has been used as a source of energy for thousands of years. Biomass as a precursor for energy storage materials is still relatively novel and faces several obstacles before becoming commonly used in today’s electrical devices. Currently, energy storage devices, such as batteries, capacitors, and supercapacitors, utilize petroleum-derived graphitic carbons for anodes, generating a need for more sustainable materials. Biomass, as a carbon-rich source for electrode materials, presents a viable and economically feasible alternative due to the prevalent lignocellulosic compounds: lignin, cellulose, and hemicellulose. Preliminary studies on the solid residues …
Strategies For Reducing Greenhouse Gases From Liquid Dairy Manure, Vera Sokolov
Strategies For Reducing Greenhouse Gases From Liquid Dairy Manure, Vera Sokolov
Theses and Dissertations (Comprehensive)
Livestock production, including the storage, handling, and spreading of manure, are among the largest contributors to greenhouse gas emissions from the agricultural sector. Liquid dairy manure storages are hot spots of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). Both CH4 and N2O are greenhouse gases (GHG) which contribute to global warming, while NH3 is an indirect source of N2O and a risk to human health. Reducing emissions from manure storages is important not only for protection of environment and humans, but also for conserving the nutrients in …
Optimisation Of Grass Measurement Technologies Through Field Experimentation And Numerical Simulation Methods, Darren Joseph Murphy
Optimisation Of Grass Measurement Technologies Through Field Experimentation And Numerical Simulation Methods, Darren Joseph Murphy
Theses
Maximising pasture utilisation through optimal grassland management is vital in terms of ensuring the economic sustainability and mitigating the environmental impact of both Irish and global pasture-based livestock production. Frequent and accurate measurement of grass quantity and quality is one of the main methods of maximising grass production and utilisation on pasture-based farms. The most prominent grass measurement tool used on Irish pasture is the rising plate meter (RPM), however, there are a range of issues with this method including operator bias, precision and difficulties in accounting for spatial variation. Currently, there is no definitive protocol for grass measurement which …
