Effects of synonymous and nonsynonymous Cyp51 mutations on DMI resistance in Cercospora beticola
(North Dakota State University, 2024)Cercospora beticola is the most devastating foliar pathogen of sugar beet. This pathogen is primarily managed by the application of fungicides, including demethylation inhibitors (DMIs). Given the broad use of DMIs in ... -
Effects of processing parameters and thickness on compression-molded PET/GF composites
(North Dakota State University, 2024)Polymer-matrix composites (PMCs) have become an integral material in many industries due to excellent strength-to-weight ratio and low cost. When semi-crystalline polymer thermoplastics, such as polyethylene terephthalate ... -
The integration of multiple cardiovascular and pulmonary models into a single unified cardiopulmonary model
(North Dakota State University, 2024)There has been an increasing effort to employ cardiovascular (CV) and pulmonary models to assist in the study of disease, answer research questions, and study the effects of a medical treatment or device. To properly study ... -
Managing Sclerotinia sclerotiorum: an emerging threat to the sugar beet industry
(North Dakota State University, 2024)Recent studies have reported S. sclerotiorum (Lib.) de Bary as an emerging pathogen of sugar beet (Beta vulgaris L.) causing leaf blight, seedling damping-off and root necrosis, becoming a fundamental production problem ... -
Unfit: Eugenics on the Northern Great Plains
(North Dakota State University, 2024)The early twenty-first century saw the emergence of the eugenics movement in the United States, which culminated in the sterilization of people with mental or physical disabilities. State institutions across the country ... -
Relationships between electronic handgrip dynamometer derived muscle function and Purdue Pegboard performance
(North Dakota State University, 2024)Purpose: To examine the relationships of electronic handgrip dynamometer and accelerometer derived maximal handgrip strength (HGS), sub-maximal control, and neuromuscular steadiness on Purdue Pegboard Test (PPT) performance ... -
The Spillover of US Monetary Policy on EU Agricultural Prices: A Panel VARX Analysis
(North Dakota State University, 2024)This research examines the nexus between US monetary policy shocks and agricultural prices of the EU. Utilizing monthly prices of beef, wheat, and barley of 21 EU countries, we estimate the impact of US monetary policy ... -
Earthquake-induced inelastic displacement ratio in reinforced concrete box girder bridges in California
(North Dakota State University, 2024)In conventionally designed bridges, the inelastic displacement is estimated using an amplification factor (R_d) suggested by AASHTO which was developed based on Single-Degree-of-Freedom system. This study models the nonlinear ... -
Wetland restoration in the North Dakota Prairie Pothole Region: a macroinvertebrate community perspective
(North Dakota State University, 2024)This study assessed the long-term recovery of aquatic macroinvertebrate communities to wetland restoration. Previous research has suggested that even after a decade post restoration, macroinvertebrate communities may not ... -
Social Factors in Healthy Aging: Strain as Risk and Support as Resilience
(North Dakota State University, 2024)Social factors are an important contributor to the healthy aging of older adults. Previous research has investigated the effects of social strain and social support on older adults’ health separately and jointly. However, ... -
Farm Operator Preferences Regarding Site Specific Weed Control Adoption
(North Dakota State University, 2024)An increasingly popular use for unmanned aerial systems (UAS) is drone applied site specific weed control (SSWC). Site-specific herbicide application allows applicators to target previously mapped weed clusters and spot ... -
An analysis of intersecting factors influencing first-generation college student enrollment
(North Dakota State University, 2024)This study examined the impact of college visits on first-generation college students (FGCS). Specifically, I analyzed data from a midsized university in the upper Midwest to understand the the intersecting effect of ... -
Large spacecraft medium voltage DC (MVDC) power and propulsion system
(North Dakota State University, 2024)This thesis introduces a medium voltage direct-current (MVDC) system for large spacecrafts with megawatt (MW)-scale power and propulsion systems for interplanetary transport. The proposed MVDC system comprises a nuclear ... -
Identification and mapping of QTL associated with crown rust resistance in recombinant inbred lines of oat (Avena sativa L.)
(North Dakota State University, 2024)Crown rust caused by Puccinia coronata f.sp. avenae is the most destructive fungal disease threatening oat production worldwide. Therefore, a search for novel sources of genetic resistance is considered essential to combat ... -
International grain origin switching: contract washouts and embedded switching options
(North Dakota State University, 2024)Changing dynamics in the international grain trading industry have led to a rise in two new contracting practices colloquially termed washouts and switching options and formally defined as contract washouts and embedded ... -
Utilizing low-tech portable caterpillar tunnels to increase productivity of warm-season vegetables and small fruits
(North Dakota State University, 2024)High tunnels and greenhouses effectively extend the growing season and protect crops from adverse environmental conditions. However, production in the less expensive and portable caterpillar tunnel has not been reported. ... -
Developing micropropagation protocol for euonymus species and evaluating oryzalin treatments for polyploid development
(North Dakota State University, 2024)Euonymus has invasive traits such as high seed production and good seed viability. Development of sterile, polyploid cultivars could prevent euonymus from invading native ecosystems. Oryzalin is a commonly used mutagen for ... -
