The Effects of Seed Source and Planting Environment on Douglas-fir (Pseudotsuga menziesii) Foliage Diseases

Creator:: Wilhelmi, Nicholas
Abstract:: Douglas-fir (Pseudotsuga menziesii) is a commercially and ecologically important tree species native to western North America. The foliar pathogens Phaeocryptopus gaeumannii, the causal agent of Swiss Needle Cast, and Rhabdocline species, the causal agents of Rhabdocline needle cast, are two important pathogens specific to Douglas-fir. These pathogens are highly influenced...

Orange tortrix : parasitoid complex and thermal constants for egg hatch

Creator:: Coop, Leonard Bryan
Abstract:: An investigation was conducted in 1980 and 1981 on the larval parasitoid complex of the orange tortrix, Argyrotaenia citrana (Fern.), a major contaminant in cane fruits (Rubus spp.) in the Pacific Northwest. A total of 13 parasitoid species were reared from 1,350 larvae predominantly collected from red raspberries in western...

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...

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...

Carbonation Kinetics of SrO By CO₂ for Solar Thermochemical Energy Storage

Creator:: Bagherisereshki, Elham
Abstract:: Given its abundance and accessibility, exploiting solar energy is a powerful approach to reduce dependency on fossil fuels for energy generation. Thermochemical reactions using concentrated solar power at high temperature are an attractive method of energy storage in support of concentrated solar power (CSP). Thermochemical energy storage of on-sun thermal...

Radiometric Calibration of EAARL‐B Bathymetric Lidar Data

Creator:: Wilson, Nicholas C.
Abstract:: The Experimental Advanced Airborne Research Lidar ‐ B (EAARL‐B), which was built and deployed by the U.S. Geological Survey (USGS) in 2014, is a novel topographic‐bathymetric lidar system. While retaining a number of features that were pioneered in the original National Aeronautics and Space Administration (NASA) EAARL system (e.g., low...

Assessment of Extraterrestrial Tracers Ir, Pt and ³He in Polar Ice Cores

Creator:: Mehmel, Nicholas C.
Abstract:: This thesis focuses on the investigation of extraterrestrial tracers Ir, Pt and 3He in polar ice cores. These tracers may be used to identify characteristics of interplanetary dust particles, and to quantify the flux of extraterrestrial material during impact events, certain volcanic eruptions, and stable background periods. In the first...

The experimental characterization of membrane behavior in two-phase gas extraction

Creator:: Cappello, Nicholas C.
Abstract:: Understanding the behavior of hydrophobic membranes is important for applications where separating a gas from a liquid-gas mixture is beneficial. For example, in-situ vapor extraction can be used in microscale heat sinks to improve heat transfer and flow stability. In this study, gas is experimentally evaluated flowing through flexible polytetrafluoroethylene...
