Drainage Water Quality Impacts Of Agricultural Management Practices: Effectof Manure Application Timing And Cover Crops, Brian Dougherty, Carl Pederson, Matt Helmers, Michelle Soupir, Dan Andersen, Antonio Mallarino, John Sawyer Sep 2019

Drainage Water Quality Impacts Of Agricultural Management Practices: Effectof Manure Application Timing And Cover Crops, Brian Dougherty, Carl Pederson, Matt Helmers, Michelle Soupir, Dan Andersen, Antonio Mallarino, John Sawyer

John E. Sawyer

A primary objective of this study is to evaluate the impact of various cropping and nutrient management systems on crop yields and drainage water quality. This progress report only includes the first-year corn grain yield results. Treatment comparisons include the impact of early fall vs. late fall vs. spring application of liquid swine manure, nitrification inhibitor with late fall swine manure application, cereal rye cover crop, and gypsum application. These comparisons will be conducted for multiple years and used to develop appropriate manure and nutrient management practices to minimize water contamination potential and enhance the use of swine manure as …

Tracking Center Of Mass With Limited Inertial Measurement Units, Connor Nathaniel Morrow Sep 2019

Tracking Center Of Mass With Limited Inertial Measurement Units, Connor Nathaniel Morrow

Dissertations and Theses

Wearable motion tracking systems pose an opportunity to study and correct human balance and posture during movement. Currently, these observations are either being conducted in laboratories with the use of camera systems and markers placed on the body, or through the use of suits containing large numbers (15-20) of inertial measurement units. However, to aid with rehabilitation of individuals with impaired balance, there needs to be an option to collect these observations outside of clinics and without incurring much cost from the user. I have focused on three inertial measurement units, one placed on each shank and one placed on …


Learning From Incidents To Reduce The Risk Of Drowning In Swimming Pools: Implementation Of Experience-Based Feedback Regarding Near-Misses In Four Public Facilities In France, Élie Vignac, Pascal Lebihain, Bastien Soulé Sep 2019

Learning From Incidents To Reduce The Risk Of Drowning In Swimming Pools: Implementation Of Experience-Based Feedback Regarding Near-Misses In Four Public Facilities In France, Élie Vignac, Pascal Lebihain, Bastien Soulé

International Journal of Aquatic Research and Education

The prevention of sports accidents must rely on a detailed knowledge of accident circumstances and risk factors. Today, very few studies have investigated in depth non-fatal drowning incidents that have occurred in public swimming pools (PSP). Learning from incidents seems likely to advance the knowledge of accident scenarios. This research study aimed to capture minor incidents that might identify safety lessons and preventive measures. Incidents of minor and major aquatic events were collected from four PSPs that had hosted 700,000 bathers per year. About 800 incidents and 300 aquatic rescues performed by lifeguards were recorded within a time frame of …


Salinity Gradient Power (Sgp): A Developmental Roadmap Covering Existing Generation Technologies And Recent Investigative Results Into The Feasibility Of Bipolar Membrane-Based Salinity Gradient Power Generation, Clifford R. Merz, Wilfrido A. Moreno, Marilyn Barger, Stephen M. Lipka Sep 2019

Salinity Gradient Power (Sgp): A Developmental Roadmap Covering Existing Generation Technologies And Recent Investigative Results Into The Feasibility Of Bipolar Membrane-Based Salinity Gradient Power Generation, Clifford R. Merz, Wilfrido A. Moreno, Marilyn Barger, Stephen M. Lipka

Clifford Merz

Besides wind and solar-based renewable energy technologies, marine sources are being actively discussed. Sources of marine renewable energy traditionally have included ocean currents, ocean waves, tides, thermal gradients, and salinity gradients. Salinity gradient power (SGP) is an attractive marine renewable resource because it possesses not only the largest energy potential but likely the largest total available resource as well. SGP is instantly available when diluted and concentrated ionic solutions are mixed; is renewable, sustainable, and produces no CO2 emissions or other significant effluents that may interfere with global climate. The ultimate challenge is in the economics of the recovery …


Effect Of Acetylation On The Mechanical And Thermal Properties Of Soy Flour Elastomers, Kendra A. Allen, Sarah Cady, David Grewell Sep 2019

Effect Of Acetylation On The Mechanical And Thermal Properties Of Soy Flour Elastomers, Kendra A. Allen, Sarah Cady, David Grewell

Sarah Cady

Biobased fillers were utilized as components in soy-elastomer composites. Soy flour is lightweight, low cost, and high strength, which makes it an ideal alternative to petroleum-derived fillers. However, poor interfacial adhesion and low dispersion within the polymer matrix are limiting factors for composite performance. Soy flour chemically pretreated by acetylation was compounded with synthetic rubber elastomers. In general, soy flour (as received) concentration in the composite is proportional to the ultimate strength. However, soy-elastomer composites with acetylated filler performed similar to the neat elastomer. In addition, the pretreated composite's thermal stability increased and exhibited less phase seperation compared to the …
