Ecological and Sociological Considerations of Wind Energy: A Multidisciplinary Study
(North Dakota State University, 2012)
Wind energy is quickly becoming a critical technology for providing Americans with renewable energy, and rapid construction of wind facilities may have impacts on both wildlife and human communities. Understanding both the ...
Attenuation of Nitrate from Simulated Agricultural Wastewater Using an Immobilized Anaerobic Biofilm
(North Dakota State University, 2012)
A number of methods are currently in use for attenuating nitrates from wastewater with varying degrees of efficiency. Bioremediation using bacteria may be an efficient and cost effective method. In an anaerobic bioremediation ...
Development and Genetic Regulation of the Novel Abdominal Appendages in the Male Sepsid Fly, Themira Biloba
(North Dakota State University, 2013)
Evolutionary novel structures are structures with no known homology. Novel structures often provide a novel function to the organism. Some species of sepsid flies (family Sepsidae) have evolved novel abdominal appendages ...
Characterization of Road Dust in Western North Dakota
(North Dakota State University, 2015)
Samples were collected during summer 2014, at three locations: along 15th St. SW near agricultural test plots, along an access road leading to a newly built oil drilling pad, and adjacent to the pad. MiniVol™ TAS Samplers ...
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 ...
Developmental Changes in Fat Metabolism of Tobacco Hornworm, Manduca Sexta
(North Dakota State University, 2012)
Insects fed high carbohydrate diets have increased fat storage, and excess fat storage in insects may have fitness costs. M. sexta larvae reared on 5.6% fat diet had lower body mass and growth rate compared to those on ...
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 ...
OSL Dating of High-Elevation Alluvial Sediments: McMurdo Dry Valleys, Antarctica
(North Dakota State University, 2015)
High-elevation alluvial fans in the McMurdo Dry Valleys are a record of short-term, occasional melting events along the margins of the East Antarctic Ice Sheet. Sediment samples were dated from five fans using Optically ...
Alluvial Fans in the McMurdo Dry Valleys: A Proxy for Melting Along Terrestrial Margins of the East Antarctic Ice Sheet
(North Dakota State University, 2013)
Surface melting along Antarctic ice sheet margins is the most poorly understood input in models of future sea level rise. Alluvial fans in the McMurdo Dry Valleys originate from meltwater produced from high-elevation ...
Population Genetics of the Western Prairie Fringed Orchid
(North Dakota State University, 2012)
The Western Prairie Fringed Orchid (WPFO) Platanthera praeclara is listed as a federally threatened species in the United States. The habitat of the WPFO is highly fragmented, causing the possibility of genetic isolation ...
