Impact of Artificial Aeration on Phytoplankton Growth and Seasonal Succession in a Eutrophic Lake
(North Dakota State University, 2016)
Excessive phytoplankton growth caused by increased loadings of nitrogen (N) and phosphorus (P) is the most visible symptoms of eutrophication. At higher densities phytoplankton creates water quality problems such as offensive ...
Ecological Complexity of Non-Native Species Impacts in Desert Aquatic Systems
(North Dakota State University, 2012)
Without an adequate understanding of complex interactions between native and non-native species, management of invasive species can result in unforeseen detrimental impacts. I used both field and laboratory experiments to ...
The Applicability of Physiology for Conservation and Management Purposes: A Case-Study Using the Breeding Season of the Red-winged Blackbird (Agelaius Phoeniceus)
(North Dakota State University, 2017)
Physiology has the potential to play a unique and important role in conservation and management practices by helping identify the mechanistic responses of populations to environmental changes, and providing physiological ...
Cell Entrapment for Mitigating Fouling in Membrane Bioreactors Treating Domestic Wastewater
(North Dakota State University, 2018)
Membrane bioreactors (MBRs) have been a process of choice for wastewater treatment and reuse because of several advantages over conventional process (activated sludge) including superior quality effluent, less biomass ...
Ammonia Oxidizing Archaea in Engineered Water and Wastewater Systems: Presence, Activity and Relationship to Heavy Metal Inhibition, and Disinfectants
(North Dakota State University, 2017)
Ammonia oxidizing archaea (AOA) have been found as a key player in ammonia oxidation. Over the past decade, AOA have been shown in some cases to outnumber ammonia oxidizing bacteria (AOB) in marine, terrestrial and aquatic ...
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 ...
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 ...
