Do Agricultural Commodity Price Spikes Always Stem From News?, Zhouxin Li
Electronic Theses and Dissertations
This study delves into the occurrence and differentiation of significant price jumps in agricultural commodity markets, challenging the conventional belief that such movements are solely driven by exogenous factors. Existing literature has primarily focused on the impact of news on agricultural commodity prices, neglecting the distinction between endogenous and exogenous price spikes. I aim to identify and categorize both types of price spikes in corn, soybean, and wheat futures markets. I propose a comprehensive methodology involving the collection of agricultural news, non-parametric price jump detection, and differentiation between exogenous (newsdriven) and endogenous (non-news related) price spikes. By utilizing intraday price …
Computational Characterization Of Extracellular Electro-Osmotic Flow During Tissue Repair, Ashley Jorgensen-Blocker
Computational Characterization Of Extracellular Electro-Osmotic Flow During Tissue Repair, Ashley Jorgensen-Blocker
Electronic Theses and Dissertations
Electrical stimulation (ES) therapy promotes the healing of chronic epidermal wounds and suppresses the degeneration of articular cartilage. Despite the success of ES therapy, the underlying mechanisms by which ES promotes tissue repair are largely unknown, preventing the standardization and optimization of treatments. One proposed mechanism involves electro-osmotic flow (EOF), electrically driven water flow generated within close proximity to the cell surface. EOF induces the transport of macromolecules and removes metabolic wastes and inflammatory molecules from these dense tissues through interstitial flow. This dissertation investigates the application of weak electric fields (EFs) to non-excitable cells and the generation of EOF …

Portable X-Ray Fluorescence Spectrometry For Sensing Salinity And Sodicity In Glacial Northern Great Plains Soils With Machine Learning Models, Adam Devlin
Electronic Theses and Dissertations
Saline and sodic soils are an increasing concern across the Northern Great Plains (NGP) due to factors of climate change and land management that are drawing geologically derived salts to the land surface. Traditional laboratory assessments, such as electrical conductivity (EC) and sodium adsorption ratio (SAR), are time and resource consumptive. Portable X-ray fluorescence (PXRF) may be a viable proximal sensing alternative, as it is able to provide elemental data in minutes, in situ or ex situ, and can directly quantify salinity-associated elements like Ca, Mg, and S. PXRF paired with predictive models has proven useful for a range of …

Delivery Of Gemcitabine, Stearoyl Gemcitabine And Paclitaxel Through Plga Nanoparticles And Its Effect On The Desmoplasia Of Pancreatic Cancer Spheroids, Rishabh Bahl
Electronic Theses and Dissertations
Pancreatic cancer is one of the deadliest cancers to treat. The primary cause for the drug resistance is the dense extracellular matrix (ECM) that surrounds the tumor and restricts blood supply. Gemcitabine (GEM) and paclitaxel (PTX) are drugs that are clinically used in the treatment of pancreatic cancer. GEM, however, is rapidly metabolized by cytidine deaminase (CDA) and eliminated from the body, and paclitaxel is a substrate for P- glycoprotein (P-gp) efflux receptors. Drug delivery using nanoparticles has been reported to help improve drug half-lives and bypass efflux receptors. This thesis aims to encapsulate PTX in PLGA nanoparticles (PTX-NP) and …

Respiratory Disease In Bighorn Sheep: A Varied Investigation Of Immunization, Transmission, And Detection, Katelin Frerichs
Respiratory Disease In Bighorn Sheep: A Varied Investigation Of Immunization, Transmission, And Detection, Katelin Frerichs
Electronic Theses and Dissertations
Respiratory disease has historically been recognized as a limiting factor to wild bighorn sheep (Ovis canadensis) herds throughout North America with epizootics resulting in large-scale die offs and reductions in recruitment. The primary etiologic agent associated with pneumonia outbreaks in bighorn sheep is Mycoplasma ovipneumoniae. This bacterial pathogen is frequently carried asymptomatically by domestic sheep (Ovis aries) and goats (Capra hircus); however, when these domestic hosts come in contact with and spread this pathogen to bighorns, the disease can cause epizootics and large-scale mortality. Domestic sheep strains are more commonly detected in bighorn sheep than domestic goat strains, and previous …

The Relationship Between Soil Test Phosphorus And Soil Biology - A Natural Management Of Soil Phosphorus Through Conservation Practices, Clarence Frederick Winter
The Relationship Between Soil Test Phosphorus And Soil Biology - A Natural Management Of Soil Phosphorus Through Conservation Practices, Clarence Frederick Winter
Electronic Theses and Dissertations
Phosphorus (P) management is an ongoing challenge in modern agriculture. Due to the importance of P in agriculture, P fertilizer additions are made throughout the U.S. to avoid nutrient-depleted soil. However, the application of P is problematic, as an excess of P in an agricultural system elevates the risk of environmental degradation, and current synthetic P sources are a fleeting resource. Additionally, a majority of P found in agricultural soils are insoluble, in the form of secondary and primary P minerals, making this large pool of P unavailable to plants. Fortunately, soil fungi organisms, such as arbuscular mycorrhizal fungi (AMF) …

This symbiosis begins with attachment of rhizobia to legume roots. Root and rhizobia surface properties play a significant role in this attachment. Another major factor affecting root colonization is bacterial competition ability. There is a lack of knowledge on the role of bacterial surface properties, competition …
Role Of Interferon Induced Transmembrane Protein 3 (Ifitm3) And Neural Precursor Cell Expressed Developmentally Down Regulated Protein 4 (Nedd4) In Seneca Virus A (Sva) Replication, Shamiq Aftab
Electronic Theses and Dissertations
In this study, we studied the role of IFITM3 in SVA replication in vitro by silencing the endogenous IFITM3 in NCI-H1299 cells. An average of 1.94-fold increase in SVA VP2 expression and an average of 4.4-fold increase in supernatant virus titer was observed after 24h SVA isolate SD15-26 infection. We have indeed observed an increase in viral mRNA copies by an average of 5-fold in IFITM3 silenced NCI-H1299 cells at 8 hpi indicating that IFITM3 restricts SVA replication post virus attachment and entry. A positive correlation between interferon-alpha induced IFITM3 upregulation and reduced SVA replication was observed. To further confirm …
