The roles of nearest neighbor methods in imputing missing data in forest inventory and monitoring databases

Creator:: Eskelson, Bianca N.I., Temesgen, Hailemariam, Lemay, Valerie, Barrett, Tara M., Crookston, Nicholas L., and Hudak, Andrew T.
Abstract:: Almost universally, forest inventory and monitoring databases are incomplete, ranging from missing data for only a few records and a few variables, common for small land areas, to missing data for many observations and many variables, common for large land areas. For a wide variety of applications, nearest neighbor (NN)...

Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

Creator:: Edwards, Sabrina R.
Abstract:: As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

Understanding the Impact of Global Warming on Orographic Rain Shadows: Insights from a Pseudo-Global Warming Simulation over the Western United States

Creator:: Koszuta, Matthew
Abstract:: Some studies using regional climate models (RCMs) suggest a weakening of the climatological rain-shadow along the Cascade and Sierra Nevada mountains during the western US cool-season. To identify the possible mechanisms of rain-shadow weakening under warming, a new set of 30-year, high-resolution (6 km) pseudo-global warming (PGW) simulations were analyzed...

Understanding Drivers of Glacier Length Variability Over the Last Millennium

Creator:: Huston, Alan C.
Abstract:: Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...

Evaluating a Zonal-mean Hydrologic Model Against a Water Tag-enabled Global Simulation

Creator:: Mandovi, Andrew
Abstract:: The hydrologic cycle on Earth comprises the transitions among the solid, liquid, and gaseous phases of water. Understanding the hydrologic cycle is of course important for climate science, but also for agricultural, drinking water, and disaster preparedness purposes. Improvements in satellite observations and general circulation models (GCMs) have led to...

Investigation of the Effect of Pulsed Direct Current on Methane Conversion and Reforming in a Point-to-Point Plasma Discharge Microreactor

Creator:: Shareghi, Adam E. L.
Abstract:: Stranded natural gas and biogas comprise a vast energy resource that is mostly wasted via flaring. This represents an opportunity to investigate novel ways to harness this resource. Nonthermal plasmas consist of excited electrons, ions and neutral atoms/molecules that have the ability to disrupt chemical bonds at ambient temperatures and...

Solar Thermal Energy System for Renewable Desalination

Creator:: McLaughlin, Ryan P.
Abstract:: Natural freshwater availability is decreasing as the global population increases. Advances in desalination technologies aim to produce fresh water in an economical way. More sustainable energy sources are desired for these desalination plants to limit the carbon footprint of water production since global carbon dioxide production is exacerbating freshwater scarcity....

Reactive Phase Change Materials for Enhanced Thermal Energy Storage

Creator:: Drake, Griffin S.
Abstract:: Effective storage and release of low-to-moderate temperature thermal energy (e.g. solar thermal or geothermal) could be transformational for applications such as space heating/cooling, domestic hot water, or off-grid cooking. Good candidates for thermal energy storage in this temperature range include latent heat storage (LHS) systems and thermochemical energy storage (TCES)...

An Investigation into the Production of Longer Hydrocarbons, Synthesis Gas, and Ammonia via a Nonthermal Plasma Microreactor

Creator:: Reddick, Ian T.
Abstract:: Nonthermal electrical plasmas can allow energy intensive reactions to occur without the use of high operating temperatures or pressures. This is because the collisions of electrons accelerated through an electric field with molecules is the cause of reactions as opposed to thermal collisions between molecules. In this study, the production...

Ultraviolet photolysis of acetaminophen in a 3D printed continuous flow reactor

Creator:: Goetze, John M.
Abstract:: Finding renewable sources of agricultural fertilizer will be necessary to ensure a stable food supply for future generations. Phosphorus is of particular concern, since mining phosphate rock is the main source and reserves are forecasted to deplete in the next 50 – 200 years. Human urine contains substantial amounts of...
