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 ...
Evaluation of a Nitrate-Assimilating Bacterium for Potential Use in Nitrate Bioremediation
(North Dakota State University, 2013)
Increasing levels of nitrate (NO3-N) in water resources have brought about the need to find ever more versatile forms of NO3-N removal from contaminated water. The ability of several microorganisms to transform NO3-N has ...

Impact of Climate Variability on Streamflow and Water Quality in the North Central United States
(North Dakota State University, 2015)
Long-term precipitation, temperature, and streamflow records were used to compare
changes in precipitation and potential evapotranspiration to changes in runoff within 25 stream basins. Historical changes in the region ...
Iron Nanoparticles and Biopolymers for Plant Nutrient Fortification
(North Dakota State University, 2016)
Novel iron (Fe) cross-linked alginate (FCA) beads were used for aqueous phosphate removal. Batch experiments were conducted with the beads using three different concentrations of phosphate (5, 50 and 100 mg PO43--P/L) as ...
Essays on Land Conversion, Crop Acreage Response, and Adoption of Conservation Practices: Evidence from the Dakota's
(North Dakota State University, 2017)
This research is composed of three essays. It highlights the driving factors of land conversion and crop acreage response focusing on North Dakota agriculture and estimates the benefits of conservation land measures at ...
Use of Biopolymer Entrapped Sulfate Reducing Bacteria and Metal Nanoparticles for Effective Aqueous Sulfate Removal
(North Dakota State University, 2013)
Sulfate reducing bacteria (SRB) isolated from activated sludge were used to investigate sulfate removal from aqueous solution using calcium alginate entrapped SRB in batch studies with ethanol and lactose as the carbon ...
Phosphate Removal and Recovery Using Iron Nanoparticles and Iron Cross-Linked Biopolymer
(North Dakota State University, 2012)
Nanoscale zero-valent iron (NZVI) particles and iron cross-linked alginate (FCA) beads were successfully used for the first time for phosphate removal and recovery. NZVI was successfully used for phosphate removal and ...
Crop Acreage Response Modeling in North Dakota and Greater Midwest
(North Dakota State University, 2017)
Our research consists of two papers. First paper focus on the trend of North Dakota (ND) crop acreage changes and include economic factors (expected prices of crops, input price, crop yield, revenue of crops) and climate ...
Northern Leopard Frogs in North Dakota: Assessing the Conservation Status of a Widespread Amphibian Species
(North Dakota State University, 2015)
North Dakota’s midcontinent location within the Prairie Pothole Region is widely known
for the dense wetlands. These highly productive wetlands are mixed within an agricultural
mosaic which places increased pressure on ...
