Extraction, Characterization, And Utilization Of Yellow Pea Starch, Abdulmalik Albu Tuwaybah

Electronic Theses and Dissertations

Dry peas, a leguminous crop, are one of the world's oldest crops, accounting for 35–40% of total pulse trade. Pea starch is an inexpensive source of starch since it can be obtained as a by-product of protein extraction. Recovering the starch from protein isolation streams (i.e., before or after) improves the environmental impact of the protein isolation process. The goal of the study was to transform low-value pea starch into highvalue starch through starch extraction and food application. Two methods of starch extraction were used (47.5% ethanol treatment and SC CO2 + EtOH extraction). Starch samples were analyzed for chemical, …

Building No-Tillage Maize Nitrogen Recommendation Algorithm That Considers Improvements In Soil Health, Dwarika Bhattarai

Electronic Theses and Dissertations

In long-term no-till fields, farmers have reported that less N is required to optimize maize (Zea mays L.) yields in long term no-tillage fields than conventional tillage fields. These reductions may be attributed to improved soil health resulting from increasing soil organic matter, higher soil microbial activities, and improved water and nutrient use efficiency. However, the impact of soil health measurements on fertilizer-N requirement has not been determined. The objective of this dissertation was to compare different regional N recommendation models to measured values and develop a maize fertilizer-N recommendation model, using machine learning approaches, that includes adjustments based on …

Relating Predator Community Ecology And Duck Nest Survival In Eastern South Dakota, Samantha R. Fino

Electronic Theses and Dissertations

As conversion of native grasslands and wetlands to croplands continues in the Prairie Pothole Region (PPR), managers are tasked with maintaining sustainable waterfowl populations. Mesopredator community dynamics is a hypothesized mechanism driving spatiotemporal variation of waterfowl nest survival in the PPR, yet studies often lack detailed information on mesopredator species occurrence and abundance. Therefore, understanding spatial and temporal variation in behaviors of mesopredators provides valuable insights for understanding predator-prey interactions between mesopredators and upland duck nests. Further, differences in a predator community resulting from lethal removal of dominant species may influence composition and space use patterns of subordinate and non-target …

Fighting For What Is Right: A Rhetorical Analysis Of The Fan Campaign To Save Anne With An E From Cancellation, Marie E. Anderson

Electronic Theses and Dissertations

The Anne with an E fan campaign highlighted storylines of social issues that fans felt were important for society. Of particular interest to the fan community was a storyline from the series in which Anne and her friends organized a protest following incidents of sexual assault and censorship aimed at silencing girls from speaking out on gendered issues. This storyline was heavily referenced in the billboards that the fan-based campaign displayed in Toronto and New York City (Anne Nation, 2020). In this analysis, I used fantasy theme analysis (Bormann, 1972) and metaphorical criticism (Osborn, 2018) to conduct a visual and …

Dark Personality, Sexual Satisfaction And Sexual Perceptions: An Event-Contingent Study, Jasmine Whitney Rios

Electronic Theses and Dissertations

Research has consistently linked Dark Personality (DP) to one’s mating tendencies (e.g., mating strategy, sexual behavior, sociosexual orientation) and sexual motivation. However, DP researchers have failed to expand the association between DP and sex beyond these common sexual dimensions. As such, there is little to no research linking DP to people’s sexual satisfaction and sexual perceptions. Additionally, personality research has predominantly investigated sexuality at the global-level (e.g., average/general report of sexual satisfaction) when studying aspects of sexual interaction at the interaction-level (i.e., soon after the interaction) can reduce various issues that accompany global measures. Thus, one purpose of this current …

Development Of A Novel Psychological Screening Tool For Young Children In Educational And Childcare Settings, Diana Tinsley

L2 Perception Of The S-Aspirated Phone In Spanish, Raúl A. Gamboa

Electronic Theses and Dissertations

This dissertation deals with the perception of the aspirated coda /s/ by Spanish L2 learners. Second language research, with some exceptions, focuses on whether L1English–L2 Spanish learners can perceive the aspirated variant, showing that only advanced learners with time spent in s-weakening regions succeed at the task. L2 studies about s-aspiration have yet to investigate the perception of the aspirated coda /s/ in different environments across actual phrases and sentences. This study focuses on the intelligibility of pairs of ambiguous phrases and sentences perceptually differentiated only by the aspirated coda /s/. Additionally, it investigates the prosodic stress´ influence on the …

Prevalence Of Meeting 24-Hour Movement Guidelines And Sociodemographic Correlates Among U.S. Adults, Samantha Cohen-Winans

Electronic Theses and Dissertations

Much evidence exists for the health benefits associated with individual movement behaviors, which include light-intensity physical activity (LPA), moderate-to-vigorous physical activity, sedentary behavior, and sleep. However, individual movement behaviors are codependent in nature and exist within a finite period of 24-hours, further underlying the importance of examining the integration of movement behaviors. Despite the absence of 24-hour movement guidelines in the U.S., the benefits of adhering to such guidelines outweigh the potential harms, such as with various levels of physical activity intensity. Moreover, many intervention studies focus on one individual movement behavior underscoring the need for studies to examine intervention …
