Glutaraldehyde Removal from Produced Water Using Photolysis and Photocatalysis
(North Dakota State University, 2017)Glutaraldehyde (GA) has been used extensively as a biocide in hydraulic fracturing fluids leading to the contamination of the compound in produced water. In this study, the performances of photolysis and photocatalysis for ... -
Identification and Characterization of Fibrous Zeolites in Western North Dakota
(North Dakota State University, 2012)The fibrous zeolite mineral erionite is a concern due to its potential for causing lung disease in humans. Studies have shown that exposure to altered volcanic bedrock containing erionite may be the explanation for a high ... -
Impact of Groundwater Table on Water Use, Yield, Root Distribution, and Seed Quality of Hard Red Spring Wheat (Triticum aestivum L.)
(North Dakota State University, 2021)The impact of groundwater table depth on hard red spring wheat (Triticum aestivum L.) yield, water use, root distribution, and grain quality were investigated in a greenhouse utilizing the lysimeter technique. Three different ... -
Impacts of Controlled Drainage and Subirrigation in The Red River Valley
(North Dakota State University, 2020)Drainage water management via controlled drainage (CD) and subirrigation (SI) has shown positive effects on water quality. To determine the impact of CD and SI in the Red River Valley (RRV), data from two fields, each with ... -
In situ Quantification of Hydrogel Entrapped Microbial Cells
(North Dakota State University, 2010)Entrapped bacteria are used in several applications including food and beverage production, antibiotic production, and wastewater treatment. To date in order to determine the viability of entrapped bacteria, they have ... -
In Vitro Enrichment of Phosphorylated Proteins From Synchronously Excysted Cryptosporidium Parvum
(North Dakota State University, 2014)Cryptosporidium is an enteric protozoan parasite that causes cryptosporidiosis and there is no effective drug treatment available. Two studies were conducted. In the first, a novel protocol was developed for the rapid in ... -
Influences on Fungal Community Composition in Roots and Soil of Coffee and Other Rubiaceae in Costa Rica
(North Dakota State University, 2019)Belowground fungi interact with plants directly as pathogens and mutualists, and indirectly as nutrient cyclers, yet the factors governing fungal community composition are poorly understood. Here I examined root and soil ... -
Interactions between Ultraviolet Light and Soybean Aphid, Aphis Glycines Matsumura (Hemiptera: Aphididae)
(North Dakota State University, 2013)Global increases in ultraviolet (UV) radiation have led to greater interest in its current and potential effects on organisms, including insects and plants. Here we report the short-term effects of UV on soybean aphids ... -
Interactions of Iron Nanoparticles with Microorganisms
(North Dakota State University, 2010)Nanoparticles (<I 00nm) are being used in different applications such as biomedical, personal care, industrial, and environmental remediation. NZVI particles have unique physico-chemical properties like high surface area ... -
Intra- and Inter-Specific Variation in Plant Responses to Climate Change
(North Dakota State University, 2022)Plants are sensitive to changing climates and are vulnerable to environmental conditions. In many regions, climate change is shifting temperatures and precipitation patterns, both of which affect various traits in living ... -
Late Pleistocene Mountain Glacier Equilibrium Line Altitudes and Paleoclimate Reconstruction in the Great Basin
(North Dakota State University, 2022)This thesis presents new reconstructions of paleoglacier surfaces and Equilibrium Line Altitudes in nine mountain ranges in the northeastern Great Basin during the Last Glacial Maximum. Improved methods for paleoglacier ... -
Late Quaternary Glacier and Climate Change in the Northeastern Great Basin
(North Dakota State University, 2021)This thesis presents a cosmogenic 10Be exposure chronology for glacial moraines within the Baker Creek valley alongside water balance and climate modeling of Pluvial Lakes Franklin and Clover. These records further limit ... -
Micro-Pore Parametrics for Optimal Hyperfiltration of Conservative Contaminants
(North Dakota State University, 2012)In compacted Na-montmorillonite membranes, the pore-size, and surface charge will influence filtration processes of solutes. A dead-end hyperfiltration setup was utilized to: (a) study the intrinsic retention, membrane ... -
Mid-Wisconsinan Climate Reconstruction Based on Fossil Beetles from Six Mile Creek, Ithaca, New York
(North Dakota State University, 2018)The history of the Mid-Wisconsinan sub-stage in northeastern North America is one of large climatic oscillations. Fossil beetles were extracted from two horizons at the Six Mile Creek site, New York. A total of 738 individuals ... -
Migratory Ecology and Wing Morphology of North Dakota Bats
(North Dakota State University, 2019)Understanding links between a species’ migratory behavior, wing morphology, and foraging strategy can provide insight into factors driving the evolution of behavioral and ecological responses. The first chapter of this ... -
Morphological Differences and Diversity of Small Mammal Species
(North Dakota State University, 2016)Small mammals play important roles in ecosystems, but are often overlooked due to their small size and plentiful abundance. Two studies evaluated the morphological differences and diversity of small mammal species based ... -
Multi-Element Analysis on Riparian Wetlands and River Sediment in North Dakota
(North Dakota State University, 2014)River sediment, transfer metals, nutrients and pollutants from various sources and tributaries within a catchment, and deposit sediment whenever the flow rate of water is low. Multi-element fingerprinting technique could ... -
Multi-Element Fingerprinting of Wetland Soil for Rapid Assessment
(North Dakota State University, 2013)Wetland functions and conditions are determined by hydrologic, soil physiochemical, and biotic states. Information obtained from soil analysis can convey wetland history due to hydrologic regime, soil chemical changes, ... -
