Disease Resistance In Wheat And Its Relatives, Ethan James Andersen

Electronic Theses and Dissertations

Plants have evolved a complex defense system against pests and pathogens utilizing many types of receptors, signaling factors, and defense compounds to detect pathogen presence and respond effectively. Since many pathogens have evolved immunesuppressing effectors used to reduce plant resistance, plants have evolved a family of receptors that detect pathogenic effectors as a result of an evolutionary arms race. These receptors contain Nucleotide-Binding Site and Leucine-Rich Repeat domains and are called NBS-LRR or NLR proteins. Many grasses possess huge genomes with hundreds of NLR-encoding genes, often found in clusters at the extra-pericentromeric regions of chromosomes, where unequal crossing over causes …

Cropping Sequence Affects Subsequent Soybean Yield, Soil Microbiome And Soil Health, Izzet Bulbul

Electronic Theses and Dissertations

Rotation is an important cultural practice that farmers use to manage crop growth and diseases. Diversified crop rotations directly affect plant residue inputs that may enrich specific groups of microbes that form beneficial associations with the following crop. At two field sites, yield differences were observed in soybeans planted after the following four long-term (14 year) crop sequences: continuous corn (CC), corn (Zea mays)/corn/soybean (Glycine max) (CCS), corn/soybean/corn (CSC), soybean/corn/soybean (SCS). Soybean yields were in decreasing order, CC>CCS>CSC>SCS, and the yield differences could not be explained by soil chemical and physical properties previously …

Relationship Of Weight-Related Eating Behaviors And Weight-Loss Of Participants In A Proprietary Weight-Loss Program, Megan Tschakert

Electronic Theses and Dissertations

The aim of this study is to evaluate weight-related eating behaviors of participants with clinically significant weight loss (CSWL) in a proprietary weight loss program. A crosssectional sample of participants (n=1,454) enrolled in a proprietary weight-loss program that includes meal replacements and health coaching were queried for weight-related eating behaviors (using Weight Related Eating Questionnaire) of routine restraint (RR), compensatory restraint (CR), susceptibility to external cues (SEC), and emotional eating (EE) in relation to CSWL (defined as having achieved a weight loss greater than 10% of starting weight). Participants were dichotomized into those with CSWL (n=973) and with no CSWL …

Maximizing Ecosystem Services Provided To The New Oil Crop Brassica Carinata Through Landscape And Arthropod Diversity, Shane Stiles

Electronic Theses and Dissertations

Prairies, once spanning the Upper Midwest, have now largely been replaced by agriculture. The lack of resources available to pollinators in agricultural fields and the practices employed by farmers to maximize yield has led to a decline in insect and pollinator diversity. There is a need to better understand how ecosystem services provided by a diverse insect community scale to current farming practices as they relate to crop yield. We sought to explain how landscape heterogeneity relates to insect and pollinator diversity, as well as how insect diversity relates to crop yield across common farming practices. To evaluate how farming …

Mass Spectrometry-Based Quantitative Proteomic Analysis Of Biological Fluids, Patience Akosua Afedi

Electronic Theses and Dissertations

Proteomics is a high-throughput approach to study protein expression, structure, function, interaction, post-translational modifications, and localization in a cell or tissue. Proteomic shotgun approach was used to analyze changes in proteins in bovine follicular fluid (FF) and plasma (PL) from cows with high estradiol (HE2) or low E2 (LE2) during the preovulatory period. FF creates a unique microenvironment in follicles necessary for follicle growth and oocyte maturation, and pre-ovulatory concentrations of E2 have been reported to impact several processes involved with fertility. Initial steps in the analysis involved development of an immunodepletion protocol for high abundant proteins (HAPs) in bovine …

Anabolic Hormone Exposure During Various Stages Of Growth: Effects On Post-Weaning Performance, Frame Size, And Carcass Characteristics Of Calf-Fed Steers, Wesley W. Gentry

Electronic Theses and Dissertations

The growth promoting activity of implants have been documented. However, stage of growth in which the implant is administered may alter growth performance and carcass traits. An experiment was conducted to examine the effects of administering a conventional implant (Synovex C; SYN-C), or an extended-release combination implant (Synovex One Grass; ONE-G) to suckling steer calves on weaning weight, post-weaning growth performance, and carcass characteristics. Suckling steer calves were either not implanted (NONE) or were implanted with SYN-C or ONE-G. Steer calves were predominantly 30 to 60 d of age when implants were administered. Steers were weaned 176 d post-suckling implant …

Assessing Listeria Risk During Different Stages Of Ice Cream Manufacturing And Storage, Neha Singh

Electronic Theses and Dissertations

Listeriosis is a life-threatening infection caused by foods contaminated with Listeria monocytogenes. Some of the major ice cream recalls in recent years reaffirm the ability of this food-borne pathogen to survive in diverse dairy processing environments and cause cross contamination. Inspection reports revealed certain lapses in implementing adequate hygienic practices for Listeria persistence in the processing environment, leading to cross contamination of ice cream. The higher levels of cross contamination of raw ice cream mix might result in random heat-injured cells when exposed to minimum heat treatment (69°C for 30 min). Evidence about the presence of injured cells in ice …

Identification And Characterization Of Stress Responsive Genes In Soybean And Sunflower, Surendra Neupane

Electronic Theses and Dissertations

Stress responsive genes encode proteins involved in plants’ response to abiotic and biotic stresses. Among such stress responsive proteins, proteins encoded by resistance genes (R genes) or nucleotide binding site-leucine-rich repeats (NBS-LRRs) and mitogen-activated protein kinases (MAPKs) are the major groups of proteins regulating biotic and abiotic stresses, respectively. Previous studies in Nepal’s lab at SDSU identified and characterized coiled coil (CC)-NBS-LRRs (CNLs), resistance to powdery mildew8 (RPW8)-NBS-LRRs (RNLs), NBS-LRR (NLs), and MAPK proteins in soybean. This study focuses on R and MAPK genes in the recently sequenced genome of sunflower as well as the toll-interleukin-1 receptor-like nucleotide-binding site leucine-rich …

Electronic Theses and Dissertations

The objective of this study was to develop Asian wheat noodle formulations enriched with oat flour and corn DDG at 10, 20 and 30 % wheat flour replacement levels and to evaluate the effects of this fiber and protein enrichment on the glycemic response of human subjects. We hypothesized that the addition of high-fiber oats and high-fiber, high-protein DDG will have synergistic effects in lowering the glycemic response in human subjects. In this study, steamed instant Asian noodles were prepared with DDG(D) and oats(OF) in combination with all-purpose wheat flour(W) in the following flour blends: (W:D) 90:10, (W:OF) 90:10, (W:D) …

Land Cover Changes Within And Around Protected Areas In Côte D’Ivoire From 1986 To 2017: A Case Study Of The Mabi-Yaya-Songan-Tamin Reserved Forests, Olena Boiko

Electronic Theses and Dissertations

Tropical forests mitigate climate change, provide habitat for the most biologically diverse terrestrial communities, and yield ecosystem services that support human wellbeing. These forests are some of the most threatened ecosystems because of the increasing human impact on the environment. Côte d’Ivoire has one of the highest deforestation rates in sub-Saharan Africa, and the expansion of agriculture to produce cash crops, such as cocoa and rubber, is presented as the primary reason for forest loss. These changes are apparent even within the boundaries of the protected areas, which raises concerns about the effectiveness of the protection strategies. This project illustrates …

Effect Of Water Velocity And Temperature On Energy Use, Behavior, And Mortality Of Pallid Sturgeon Scaphirhynchus Albus Larvae, Joseph Thomas Mrnak

Electronic Theses and Dissertations

Pallid Sturgeon Scaphirhynchus albus are a federally endangered species endemic to the Missouri River basin. Natural reproduction has been limited for decades and a recruitment bottleneck is hypothesized to occur during the larval stage of development. Understanding factors that affect survival of Pallid Sturgeon larvae is key given their critical status and ongoing recovery efforts. In this study, I evaluated the effects of water velocity and temperature on energy use, behavior, and mortality of endogenously feeding Pallid Sturgeon larvae (< 25 mm TL). In the first experiment, I examined the effect of water velocity (0 – 8.3 cm s⁻¹) on larval growth, energy density, swimming activity, and mortality. Larval growth rate at 16.3 °C was similar across …

A Critical Review Of Using High Viscosity Friction Reducers As Fracturing Fluids For Hydraulic Fracturing Applications, Mohammed Ba Geri, Abdulmohsin Imqam, Ralph E. Flori

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The primary purpose of using traditional friction reducers in stimulation treatments is to overcome the tubular drag while pumping at high flow rates. Hydraulic fracturing is the main technology used to produce hydrocarbon from extremely low permeability rock. Even though slickwater (water fracturing with few chemical additives) used to be one of the most common fracturing fluids, several concerns are still associated with its use, including usage of freshwater, high-cost operation, and environmental issues. Therefore, current practice in hydraulic fracturing is to use alternative fluid systems that are cost effective and have less environmental impact, such as fluids which utilize …

Should Robots Prosecute And Defend?, Stephen E. Henderson

Faculty Articles

Even when we achieve the ‘holy grail’ of artificial intelligence—machine intelligence that is at least as smart as a human being in every area of thought—there may be classes of decisions for which it is intrinsically important to retain a human in the loop. On the common account of American criminal adjudication, the role of prosecutor seems to include such decisions given the largely unreviewable declination authority, whereas the role of defense counsel would seem fully susceptible of automation. And even for the prosecutor, the benefits of automation might outweigh the intrinsic decision-making loss, given that the ultimate decision—by judge …

Appendices: Failures, Errors And Mistakes: A Systematic Review Of The Literature, Amber Simpson, Adam V. Maltese, Alice Anderson, Euisuk Sung

Teaching, Learning and Educational Leadership Faculty Scholarship

Terms such as failure, mistakes, errors, obstacles, and struggle are used interchangeably, but each carry different connotations and discipline-specific meanings. Reactions to experiencing a failure can range as well, from being seen as having educative value to be debilitating. These reactions are based on criteria like environment, prior experiences and individual characteristics, to name a few. The purpose of this chapter is to synthesize and clarify how these terms are articulated and utilized in research studies and commentaries published between 1970 and 2017. Through a systematic literature review, we will discuss similarities and differences in how researchers defined these terms, …

Religious Addiction, Adam Chiang Toler

Undergraduate Student Research Awards

It is to my understanding that religion, at its best, is a choice – a choice that manifests one’s conception of humanity in relation to the sacred. Yet, I intend to discuss religion at its worst – religion as an addiction, as a meta-determinant of choice. This is to say that religion harbors the potential to evolve into a subjugating agent akin to drug addiction. To deal in terms of both religion and addiction, I am tasked with incorporating a diversity of disciplines. It is tempting to endeavor into this inquiry with a sense of semantic sensationalism, conducting a cursory …
