Impact of Dairy Manure Digestate on Microbial Activities in Soil

Creator:: Waggoner, Ashley L
Abstract:: Amendments and fertilizers applied to optimize crop production and improve soil health also supply inputs of soil organic matter (SOM) and nutrients that affect soil microorganisms. In the dairy-intensive Pacific Northwest, dairy manure is stored as slurry mixtures until conditions are appropriate for soil application. During storage, the manure begins...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...

Investigation of unique marine environments for microbial natural products

Creator:: Thornburg, Christopher C.
Abstract:: Metagenomics has revealed that the marine microbial biosphere is immensely more diverse than originally considered, and is an almost untapped reservoir for the potential discovery of microbial natural products. Despite numerous advances in culturing, biosynthetic engineering and genomic-based screening efforts to uncover much of this diversity in relatively accessible environments,...

Analyzing the Kinetics and Thermodynamics of Surface Reactions using Density Functional Theory

Creator:: Sprowl, Lynza H.
Abstract:: The interactions of chemical species with a solid surface play a role in many everyday applications such as heterogeneous catalysis, corrosion, and degradation reactions. Understanding the reaction kinetics and thermodynamics via rate constants and equilibrium constants, which require knowledge of the adsorbed species’ entropy, is essential for tuning these surface...

Studies on 1-deoxy-D-xylulose 5-phosphate reductoisomerase from Synechocystis sp. PCC6803 : characterization of mutants and inhibitors

Creator:: Fernandes, Roberta P. M.
Abstract:: In recent years, the methyl erythritol phosphate (MEP) pathway to isoprenoids has been the subject of intensive research. The interest is because isoprenoids have important roles in many cellular processes essential for the survival of several pathogenic organisms, making the inhibition of this pathway an attractive target for the drug...

Investigating Timescales of Resurgence at Large Calderas: Post-74 ka Activity at Toba Caldera, Sumatra, Indonesia

Creator:: Mucek, Adonara E.
Abstract:: The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...

Development of bi-based lead-free piezoelectric materials : thin film piezoelectric materials via PVD and CSD routes

Creator:: Jeon, Yu Hong
Abstract:: Piezoelectric materials have been widely used in electromechanical actuators, sensors, and ultrasonic transducers. Among these materials, lead zirconate titanate Pb(Zr[subscript 1‐x]Ti[subscript x])O₃ (PZT) has been primarily investigated due to its excellent piezoelectric properties. However, environmental concerns due to the toxicity of PbO have led to investigations into alternative materials systems....

Understanding of Ferroelectric to Relaxor Phenomenon in Bismuth-based Perovskite

Creator:: Gupta, Sanu K.
Abstract:: It has been well established that ferroelectric to relaxor crossover in piezoelectric ceramics exhibit promising electromechanical and dielectric properties over a wide temperature range, applying sensors and actuators transducers and such. A plethora of research has reported giant strain in various lead-free piezoelectric ceramics and attributed the reasoning to the...

Efficient training and feature induction in sequential supervised learning

Creator:: Hao, Guohua
Abstract:: Sequential supervised learning problems arise in many real applications. This dissertation focuses on two important research directions in sequential supervised learning: efficient training and feature induction. In the direction of efficient training, we study the training of conditional random fields (CRFs), which provide a flexible and powerful model for sequential...

Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

Creator:: Walker, Anthony S.
Abstract:: Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...
