Tree Species Selection Across Municipalities in the Pacific Northwest

Creator:: Petter, Joshua S.
Abstract:: There are many benefits provided by trees in urban areas. While there are many recommendations on maximizing the returns from urban trees, there has been little research examining how these managers are prioritizing their tree species selection. A survey instrument was constructed to survey Tree City USA designated cities across...

Impacts of Stocking Density on Development and Puberty Attainment of Replacement Beef Heifers

Creator:: Schubach, Kelsey M.
Abstract:: The following experiment presented herein compared growth, physical activity, stress-related responses, and puberty attainment in heifers reared on high- (HIDENS) or low-stocking densities (LOWDENS). Sixty Angus x Hereford heifers were ranked by age and BW (210 ± 2 d and 220 ± 2 kg, respectively) on d 0, and assigned...

The Role of Tumor-Derived Exosomes in the Development of Carboplatin Resistance in Canine Osteosarcoma

Creator:: Weinman, Marcus
Abstract:: Many humans and canines alike suffer from osteosarcoma, which is often metastatic, resistant to chemotherapy, and frequently fatal. The mechanisms through which osteosarcoma cells acquire resistance to chemotherapy are not entirely understood, and the role of exosomes as intercellular mediators of this resistance in osteosarcoma is unknown. Using established canine...

Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:: Bartow, Shannon M.
Abstract:: The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...

Leveraging multi-sensor time series datasets to map short- and long-term forest disturbances and drivers of change in the Colombian Andes

Creator:: Murillo Sandoval, Paulo Jose
Abstract:: The spatial distribution of forest disturbance is commonly calculated using a satellite imagery-driven bi- or tri-temporal change analysis. Working in Colombia’s Cordillera de los Picachos National Natural Park – a region of consistent cloud cover and dramatic topographic relief – a change assessment with such infrequent observations cannot capture long-term...

Flex-shape convolution and an interactive image segmentation system

Creator:: Zhou, Zheng
Abstract:: Semantic image segmentation is a relatively difficult task in computer vision. With the advent of deep learning, semantic image segmentation is increasingly of interest for researchers because of the excellent predictions from Convolutional Neural Network (CNN). However, CNNs have proven to struggle with obtaining global context of image due to...

Classifying and Synthesizing 3D Shapes of Objects using Deep Neural Networks

Creator:: Xu, Xu
Abstract:: Reasoning about 3D shape of objects is important for successful computer visionapplications in robotics, 3D rendering and modeling. In this thesis, we address twoproblems { First, given an image, we generate 3D shape of the foreground object thatappears in the image. Second, we predict the class label of the input...

Exploring mechanisms that drive the development of reversible soil hydrophobicity

Creator:: Woolverton, Priscilla B.
Abstract:: This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...

Constraints to urban park visitation : Conceptual connections and spatial attributes for traditionally well-served and underserved residents

Creator:: Rushing, Jaclyn R.
Abstract:: Connecting with nature is associated with social, physical, and emotional benefits such as stress relief, improved physical health, and lower crime. Parks and other natural areas offer spaces in which to connect with nature and reap these and other benefits (e.g., family bonding, social events, learning). Despite increasing populations of...

Aspen Drought Stress Response, Snow Cover and Soil Moisture Dynamics on an Oregon Bunchgrass Prairie

Creator:: Neary, Andrew
Abstract:: Quaking aspen, Populus tremuloides, has experienced severe declines in recent years in part due to the effects of changing climate and extreme drought. As the dominant deciduous tree in Western North American forests, aspen plays a critical role in forest biodiversity and ecosystem function. Therefore, the persistence of this species...
