In-Silico Investigation of Geological and Biological Materials by Molecular Dynamics Simulations
(North Dakota State University, 2021)Molecular dynamics (MD) simulation is a computational technique that predicts the time-dependent behavior of a molecular system utilizing molecular mechanics. MD simulations are extensively employed in the scientific arena ... -
Lignin and Cellulose Nanofibers Enhanced Corn-Based Thermoplastic Composites
(North Dakota State University, 2021)The goal of this project is to develop biobased thermoplastics and composites using corn as the main raw material. Corn contains mainly starch, zein, and oil. Thermoplastic starch/zein blends were prepared through internal ... -
Phasor Measurement Unit Placements for Complete Observability using Linear-Time, Quadratic-Time, and Subquadratic-Time Heuristics
(North Dakota State University, 2010)A phasor measurement unit (PMU) is considered to have the potential to improve the efficiency of electric power systems by monitoring, control, and protection. Through measurements of all bus voltages, incoming and ... -
Mottling the conversation: an evolving debate
(North Dakota State University, 2009)Online forums have often been considered a medium of equality. However, after studying Amazon.com communities taking part in the evolution/intelligent design debate, it became clear that these communities were substituting ... -
Estrogen Receptors Signaling in Airway Smooth Muscles: Role in Intracellular Calcium Regulation and Contractility
(North Dakota State University, 2021)Epidemiological evidence suggests higher incidence and severity of asthma in pre-menopausal women and aging men, suggesting a role of sex steroids, especially estrogen. In this regard, it is not clear whether specific ... -
Genome-Wide Association Mapping and Genomic Prediction for Resistance to Sclerotinia Stem Rot in Rapeseed/Canola (Brassica napus L.) Germplasm Collections
(North Dakota State University, 2021)Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum, is a devastating disease of rapeseed/canola that causes significant seed yield loss, reduced oil content, and quality. Lack of complete immune genotypes and ... -
Rationally Reconstructed and Attenuated Vaccines for Epidemic Response
(North Dakota State University, 2021)Most of the recent viral outbreaks were caused by highly mutating RNA and single stranded DNA viruses. The availability of safe and effective rapid response vaccines early on in an epidemic situation, along with good vaccine ... -
Moisture Sensitivity of PLA/PBS Blends During Ultrasonic Welding and Fused Deposition Modeling
(North Dakota State University, 2021)Moisture absorption into hygroscopic/hydrophilic materials used in fused deposition modeling (FDM) and ultrasonic welding (USW) can diminish desired mechanical properties. Sensitivity to moisture is dependent on material ... -
Development and Characterization of Reactive Extrusion Additive Manufacturing System and Polymer
(North Dakota State University, 2021)Additive manufacturing with polymers can rapidly produce complex geometry and prototypes but does not usually utilize thermoset polymers aside from photocurable polymers. In this study two-part reactive thermoset resin ... -
Of Inclusion, Belonging, and Missed Connection in Higher Education
(North Dakota State University, 2021)Inclusion research in higher education affords opportunities to measure how, and to what extent, institutions create academic environments that are equitably accessible. While inclusion encompasses many facets, underscored ... -
Variation, Energy Consumption, Latency, and Failure Aware Design for Memristive ANNs
(North Dakota State University, 2021)As a novel non-volatile device, the memristive crossbar array has delivered many promises in giving low computation complexity, high energy efficiency, and high density for neuromorphic computing. However, the intrinsic ... -
Optimizing Glufosinate for Weed Control in Agricultural Systems
(North Dakota State University, 2021)Weed management is an essential component of production agriculture. While many weed management methods exist today, chemical practices have proven to be the most efficient and are the most widely adopted methods. The ... -
Mechanistic Investigation of Catalytic Chlorite Decomposition by Chlorite Dismutase
(North Dakota State University, 2021)Water purification processes often involve chlorine-based disinfectants which consequently leads to formation of chloro oxyanions (ClOx−), potent water-soluble oxidizing agents. These chlorine species are kinetically stable ... -
Implementation of Parallel Programming to Improve Transaction Speed and Scalability in Blockchain Systems
(North Dakota State University, 2021)This thesis presents a parallel mining architecture model intended to be used in blockchain systems to improve transaction speed and network scalability while maintaining decentralization. Typical blockchain validation ... -
Environmental Factors Influencing Tumor Associated Pericyte Phenotype in Pancreatic Cancer
(North Dakota State University, 2021)Pancreatic ductal adenocarcinoma (PDAC) is the third leading cause of cancer death in the U.S. with a 5-year survival rate of 11%. PDAC patients suffer from the lack of effective treatment options largely due to the limited ... -
Freshwater Cyanotoxin Mixtures in Recurring Cyanobacterial Blooms in Voyageurs National Park
(North Dakota State University, 2021)Algal and cyanobacterial blooms can foul water systems, inhibit recreation, and produce cyanotoxins, which can be toxic to humans, domestic animals, and wildlife. Blooms that recur yearly present a special challenge, in ... -
