Development and Scale Up of Aqueous Surfactant-Assisted Extraction of Canola Oil for Use as Biodiesel Feedstock
(North Dakota State University, 2012)
In oilseed extraction, alternative extraction media have been studied to replace the traditional solvent, hexane, due to health, safety, and environmental concerns. In this work, aqueous surfactant-assisted extraction was ...
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 ...
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 ...
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 ...
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 ...
