Responses Of Soil Surface Greenhouse Gas Emissions To Nitrogen And Sulfur Fertilizer Rates To Brassica Carinata Grown As A Bio-Jet Fuel, Dwarika Bhattarai, Gandura O. Abagandura, Thandiwe Nleya, Sandeep Kumar

Agronomy, Horticulture and Plant Science Faculty Publications

Carinata (Brassica carinata A. Braun), a non-food oilseed crop and an alternative bio-jet fuel feedstock, has received attention for its potential as a low-input option for production in the semi-arid region of the Northern Great Plains of the United States. Research addressing the impacts of nitrogen (N) and sulfur (S) fertilizers on soils and greenhouse gas (GHG; CO₂, N₂O, and CH₄) emissions from carinata production are limited. Thus, objective of this study was to evaluate the impact of different rates of N and S fertilizers applied to carinata on soil properties and GHG …

The Importance Of Care Coordination Of Patients With Multimorbidity: An Evaluation Of The Patient-Centered Medical Home Model, Mary Boksa

Biology and Microbiology Graduate Students Plan B Research Projects

The rise in multimorbidity among various patient populations has made fragmentation of care an increasingly common issue due to the need for specialized care of each chronic condition and complexity of treatment plans. Implementation of care coordination intervention models has been identified as an essential component in combating this fragmented nature of our current health care system. This is done by providing an organized model of care and improving communication between all parties involved in care and treatment plans. This literature review will begin with a brief discussion on the importance of care coordination and components needed for implementation and …

The Relationship Between Land Use Change And Disease Prevalence, Allison Bjornstad

Biology and Microbiology Graduate Students Plan B Research Projects

Zoonotic disease outbreaks are becoming more novel and are increasing in frequency. This increase can be partially attributed to land use changes including deforestation, urbanization, and cultivation. Land use change alters disease prevalence by causing an increase in contact rates between disease hosts and humans. Land use changes also alter species compositions in the area to contain more competent disease hosts. Each pathogen can react to these changes in different ways. The specific reactions that each pathogen has to land use changes should be further researched so proper mitigation steps can be taken. Once the effects of land use change …

Polycystic Kidney Disease: An Examination And Review Of Disease Type, Presentation, Treatment, And Prognosis, Zoey Mann

Biology and Microbiology Graduate Students Plan B Research Projects

Polycystic Kidney Disease (PKD) is a ciliopathy that primarily presents as renal cysts. Inherited as either a dominant (ADPKD) or recessive (ARPKD) mutation, PKD is one of the most commonly inherited kidney diseases. ADPKD is caused by the inheritance of a mutation in either PKD1 or PKD2, which code for the polycystin-1 and -2 proteins, respectively. The less severe form of PKD, ADPKD is typically adult-onset, with the possibility of extremely late-stage presentation. In addition to renal cysts, hepatic and pancreatic cysts are common, as well as other non-cystic symptoms including headache and hypertension. ARPKD is caused by the inheritance …

Current And Future Perspectives In The Treatment Of Fracture Nonunions, Zebadiah Nelson

Biology and Microbiology Graduate Students Plan B Research Projects

Fracture nonunions comprise one of the serious clinical complications in orthopedics. Fracture nonunions result when the time to union is greater than 6 to 9 months. It is estimated that approximately 5% to 10% of all fractures progress to fracture nonunion due to a host of complicating patient variables and risk factors. New scoring systems have emerged which help in directing the treatment strategies. Fracture nonunion management should be directed toward maintaining the diamond concept which introduces osteogenic cells lines, an osteoconductive scaffold for those cells to grow, as well as the necessary growth factors, and a stable mechanical microenvironment. …

Association Between Colorectal Cancer Prevalence And Patients Age, Race And Sex, Arsiema Fisuh

Biology and Microbiology Graduate Students Plan B Research Projects

Colorectal cancer is one of the top leading causes of cancer deaths affecting people of different ages, sex and races disproportionately. The American Cancer society researchers have studied that lack of physical activities, smoking, consumption of red meat, and heavy alcohol use to be high risk factors for developing colorectal cancer in addition to genetic inheritances. Previous research studies have shown that disparities in cancer screening, socioeconomic status and others impacts on colorectal cancer prevalence and death. The objective of this project is to review the existing literature to better understand the disparities in colorectal cancer prevalence and deaths in …

Identification Of Loci Influencing Teosinte Crossing Barrier 1 (Tcb1) Efficacy In Maize By Quantitative Trait Loci (Qtl) Mapping And Genome-Wide Association Study (Gwas), Namrata Maharjan

Electronic Theses and Dissertations

Pollen cross-contamination has been a major problem for maize breeders. Various mechanical methods applied to avoid the contaminations are ineffective. The genetic factors related to maize fertilization can be used to develop an effective method to prevent pollen contamination. Pollen rejection ability controlled by Teosinte crossing barrier 1 (Tcb1) is such a genetic system. Silks possessing dominant Tcb1-s reject pollen possessing the recessive allele (tcb1). Successful fertilization occurs when Tcb1-s pollen falls upon tcb1 silks. The efficacy of dominant Tcb1-s was, however, reduced when repeatedly backcross with maize inbred lines, which suggests that there are modifiers to Tcb1-s. To find …

Pollinator Ecology In Agroecosystems Of Eastern South Dakota, Isabela Beatriz Vilella-Arnizaut

Electronic Theses and Dissertations

Community structure contributes to ecosystem persistence and stability. To understand the mechanisms underlying pollination and community stability of natural areas in a human influenced landscape, a better understanding of the interaction patterns between plants and pollinators in disturbed landscapes is needed. Furthermore, understanding the potential conservation value in green spaces such as botanical gardens could assist in preserving and bolstering plant-pollinator interactions. Our study takes place in the Northern Great Plains which still retains extensive tracts of remnant temperate grassland habitat within a matrix of varying land-uses. First, we used a network-based approach to quantify how temperate grassland attributes and …

The Effects Of Saline Soil On Microbiome And The Isolation Of Root-Associated Microbes To Relieve Salinity Stress, Duncan Jakubowski

Electronic Theses and Dissertations

Increasing levels of salinity in once-viable lands for crop production is a serious and growing problem in the Northern Great Plains. The objectives of this study were to determine the effects of saline soil on the microbial composition of plant roots and bulk soil, to measure metabolic changes in plant roots from saline soil, to determine the viability of root-associated microbes as inoculants to increase stress tolerance in plants, as well as determine the impact of saline soil on nitrogen cycling genes linked to greenhouse gas production. This study hypothesizes that high soil salinity levels have a significant impact on …

Bio-Inspired Materials For Electrochemical Sensors, Matthew Joseph Hummel

Electronic Theses and Dissertations

Electrochemical biosensors are a rapidly growing research area that has greatly improved its specificity, accuracy, and precision in the detection of biomolecules in contemporary literature and industry alike. Typically, these systems exist in a three-electrode conformation with a working electrode functioning as the anode, a counter electrode functioning as the cathode, and a reference electrode allowing for the control of potential in the system. The method by which these sensors work is through the sharing of electrons via redox reactions with the target molecule and the working electrode or modifications on its surface. By exploiting the function of biomaterials that …

Guillain-Barre Syndrome: A Review Of Current Diagnostic Tools, Treatments, And Research, Kaitlyn Hespen

Biology and Microbiology Graduate Students Plan B Research Projects

Guillain-Barre Syndrome is a rare post-infection inflammatory disorder. It is caused by the cross-reactivity of antibodies produced from a recent infection which then attack the gangliosides of the peripheral nervous system. Guillain-Barre syndrome includes multiple subtypes which are categorized based on both disease course and symptoms, which include length of progression phase, pain, and cranial nerve involvement. This paper will serve as a review of diagnostic tools and treatment options used for Guillain-Barre syndrome patients. It will also discuss recent research on these topics as well as studies on viral outbreaks which may be linked to Guillain-Barre syndrome. These will …

Electrical Sensing In Non-Excitable Cells To Promote Galvanotaxis And Tissue Survival, Anyesha Sarkar

Electronic Theses and Dissertations

Weak DC fields have been shown to induce polarity, cell migration and cell proliferation in 2D cultures in vitro. To understand the mechanism by which non-excitable cells sense such weak EFs, we have investigated the mechanism of cathode-directed water flow (electro-osmosis) in the boundary layer of cells by reducing it with neutral, viscous polymers. Our results indicate that low molecular weight polymers decrease cathodal migration and promote anodal migration in a concentration dependent manner. High molecular weight polymers do not affect directionality and can be explained using porosity and hydraulic permeability between the polymers. These results provide the first evidence …
