Development Of Mathematical Model For Abiotic Stresses And Cotton Fiber Quality, Suresh Bajirao Lokhande

Theses and Dissertations

Abiotic stresses cause extensive losses to agriculture production worldwide. Cotton (Gossypium hirsutum L.) is an important fiber crop grown widely in subtropical region where temperature, water and nutrients are the common factors limiting crop production. Such losses could be more severe in the future climate as intensity and frequency of those stresses are projected to increase. The overall goal of this study was to evaluate effects of abiotic stresses on cotton reproductive performance and develop functional algorithms for fiber properties in response to different stress factors. Three experiments were conducted to evaluate the effects of temperature, water, and nitrogen in …

Evaluating User Satisfaction And Perceived Quality Of Electronic Health Records In Mississippi, Dakota Chamblee

Theses and Dissertations

Electronic Health Records (EHRs) is a health information technology that has already begun to change the way healthcare providers care for patients. EHRs can potentially enhance the quality and efficiency of patient care (Simon et al., 2010); however, some research shows that EHRs do not always do so. The lack of improved efficiency and quality of care can lead to frustrated and dissatisfied users. The effects of different aspects of EHR implementation could affect user satisfaction and perceived quality of EHRs. This study investigates the how time since implementation, training, and leadership affect user satisfaction and perceived quality of the …

Seed And Waterbird Abundances In Ricelands In The Gulf Coast Prairies Of Louisiana And Texas, Joseph Roy Marty

Theses and Dissertations

Rice not collected by harvesters and natural seeds are important foods for waterfowl. Estimation of abundance of these seeds is necessary for calculating waterfowl habitat conservation needs in the Louisiana Chenier Plain (LCP) and Texas Mid-Coast (TMC). My objectives were to quantify dry mass of rice and other seeds from August-November 2010, and estimate waterbird abundances on farmed and idle ricelands in these regions from December 2010-March 2011. Rice abundance in farmed ricelands ranged from 159.7 kg/ha (CV = 66.6%) to 1,014.0 kg/ha (CV = 8.3%). Natural seed abundance in idle ricelands ranged from 99.7 kg/ha (CV = 32.9%) to …

Survival, Habitat Use, And Spatiotemporal Use Of Wildlife Management Areas By Female Mallards In Mississippi's Alluvial Valley, Joseph David Lancaster

Theses and Dissertations

The Mississippi Alluvial Valley (MAV) is an important region for wintering mallards (Anas platyrhynchos) in North America, yet little is known about their spatiotemporal habitat use and related survival in Mississippi. I tracked 126 radio-marked female mallards to quantify survival, habitat use, and use of wildlife management areas (WMAs) with experimental hunt regimes in the south MAV of Mississippi during winters 2010-2012. Daily survival was greatest in agricultural (0.997) and moist-soil (0.999) habitats in winters 2010-2011 and 2011-2012, respectively. Overall interval survival across both winters was 0.60 (SE = 0.02). Forested (40-54%) and moist-soil wetlands (41-59%) received greatest use diurnally …

Quality Of Corn Silage Inoculated With L. Buchneri And P. Pentosaceus, Kellie Nichole Kaletsch

Theses and Dissertations

Microbial inoculants are forage additive products that contain viable bacteria and sometimes a combination of enzymes. Bacterial inoculants are used primarily for two reasons; first to gain rapid fermentation and second to decrease or inhibit spoilage. Inoculants work by shifting the fermentation of forage crops. The shift of fermentation causes preservation of nutrients, dry matter (DM) and occasionally increases animal performance. Most inoculants contain lactic acid producing bacteria to aid in shifting fermentation to lactic acid and away from acetic acid and ethanol production; however some inoculants aid in aerobic stability enhancement by production of acetic acid.. Although most inoculants …

System Dynamics Simulation Model Of Salmonella Contamination Of Broiler Carcasses In The Chill Tank Of A Poultry Processing Plant, Karen Dazo Galarneau

Theses and Dissertations

Salmonella has been studied and researched for more than a hundred years and yet it remains a problem for human and animal health. The goal of this dissertation was to apply the systems thinking approach to Salmonella contamination and develop a System Dynamics (SD) simulation model for Salmonella contamination in the chill tank of a poultry processing plant. But first the appropriate carcass rinse sampling method that would not impact on the resulting Salmonella contamination status of the broiler carcass was studied. Kappa agreement analysis was used to evaluate three sampling methods. The adjacent rinse method was found to be …

The Effect Of Low Sodium Diet Education In The Prevention Of Hospital Readmission For Heart Failure Patients, Lindsey Tira Doxtater

Theses and Dissertations

Rate of readmission among hospitalized heart failure (HF) patients is used as an indicator of quality and efficiency of healthcare. A low sodium diet is a component of the accepted treatment for HF. Instruction by dietitians may help reduce dietary sodium without negatively affecting quality of life. The effect of low sodium diet education on hospital readmission within 30 and 45 days of discharge for HF patients (N=52) was conducted. Chi-square analysis determined education did not significantly affect remittance within 30 (P=.143) or 45 days (P=.474). Patients readmitted within 30 days were older (P=.005). Men were more likely to be …

The Effects Of Low Atmospheric Pressure And Electrical Stunning On The Instrumental And Sensory Quality Of Broiler Breast Meat Deboned At 45 Minutes And 4 Hours Postmortem, Vijayakumar Radhakrishnan

Theses and Dissertations

Low Atmospheric Pressure Stunning (LAPS) has recently become available to the broiler industry. Therefore, research was conducted to determine the effect of stunning method (LAPS and Electrical Stunning(ES)) and postmortem deboning time (0.75 hr and 4 hr) on the instrumental and sensory acceptability (3 replications) of breast meat (n=576, 144 birds per treatment) prepared using different cooking methods (fried, baked, sous vide). Breast meat was evaluated for pH, CIE L*a*b*, yields, shear force, and consumer acceptability. Postmortem pH decline was more rapid (P<0.05) in the breast meat of LAPS stunned birds when compared to ES stunned birds, but no differences existed (P>0.05) among treatments with respect to final pH. On average, no differences (P > 0.05) existed in the …

Formation Of Oxidative-Stress Resistant Phenotypes Of Listeria Monocytogenes Serotypes 1/2a And 4b And Their Stability At 37oc And 4oc, Piumi De Abrew Abeysundara

Theses and Dissertations

The purpose of this study was to induce an oxidative-stress adaptation in Listeria monocytogenes Bug600 (serotype 1/2a) and F1057 (serotype 4b) by pre-exposing to sublethal H2O2 and alkali-stress either singly or sequentially. Our findings show that the sequential pre-exposure of cells to pH 9 for 30 min treatment followed by 50 ppm H2O2 for 30 min at 37°C yielded the highest oxidative-stress resistant phenotypes of L. monocytogenes Bug600 and F1057. The sublethal H2O2 and sublethal alkali-stress induced oxidative-stress adaptations were completely reversible within 60 min at 37°C in the absence of such sublethal stress. However, the oxidative-stress adaptation induced at …

Developing A Multistage Model For Treponemal Disease Susceptibility, Sarah A (Sarah Ann) Mathena

Theses and Dissertations

Despite numerous studies, little is known about the influential factors impacting treponemal disease susceptibility. Yet, forms of treponemal disease, specifically yaws, are a major source of morbidity in the developing world. Bioarchaeological materials may assist with deficit by testing full ranges of disease expression. This study explores the relationship between treponemal disease ecology, specifically yaws, and susceptibility through six southeastern United States archaeological samples. Results show early life health experiences have a relationship to later life disease expression. However, influences of climate may only be seen at a cross-regional level. Finally, although nutrition, as evidenced by subsistence strategy, may play …

Certain Agave Species Exhibit The Capability To Be Moderately Productive Under Conditions Of High Salt And Drought Stress, Steven J. Bergsten

Theses and Dissertations

Water availability and arable lands are increasingly limiting resources in many parts of the U.S., particularly in semi-arid and arid regions. As a means of addressing food and fuel demands associated with burgeoning population growth, highly productive and water-use efficient crops need to be identified. One potential crop, Agave, merits consideration and evaluation due to its putative capability to provide sustenance and energy despite growing in water-limited regions and on marginal soils. However, little is known regarding the productivity these succulent plants will have under growing conditions of the Southwest, where high concentrated saline soils are abundant, and water is …

The Design, Implementation And Evaluation Of A Technology Solution To Improve Discharge Planning Communication In A Complex Patient Population, Susan M. Manfredi

Doctor of Nursing Practice (DNP) Projects

Unnecessary delays in discharge planning can extend the length of stay (LOS) and add non-reimbursable days for socially and medically complex patients thereby increasing the financial burden to healthcare organizations. The literature supports enhanced discharge communication strategies and the use of checklists to facilitate safe and timely discharges. Following root cause analyses of significant discharge delays, one hospital identified gaps in communication as key precursors associated with discharge planning breakdown when discharging patients to skilled nursing facilities. Review of these events demonstrated the need for concurrent communication strategies between multidisciplinary care team members in planning for complex discharges.

Factors Influencing Youth Self-Perceptions Of Overweight And Obesity, Caitlin Helen Sommers

Dissertations and Theses

This study sought to examine whether participation in physical activity affects the ability to correctly classify body size, based on body mass index classifications. Secondarily, this study determined whether adolescents who incorrectly classified their body size overestimated or underestimated their size. Self-report data from the Youth Risk Behavior Surveillance Survey collected by the Centers for Disease Control and Prevention were analyzed. Logistic regression was performed to examine relationships between self-perception of body size and physical activity, television viewing time, computer/video game use, physical education class time, and extracurricular sports activities. Significance was set to p<0.05. Physical activity was the only statistically significant independent variable (p=0.058, OR = 1.060). Although physical activity was shown to be statistically significant, it did not appear to meaningfully increase the ability of youth to correctly classify body size. Secondary analysis showed that adolescents who incorrectly classified their body size were more likely to underestimate their body size. Females more frequently underestimated their body size (females=673; males=384).

Cameroon, one of the countries in the world that continues to criminalize homosexuality, has been on the news recently due to the torture and murder of young journalist and gay activist, Eric Ohena. This paper examines the discrimination faced by the LGBTI community in Cameroon by exploring the origins of homophobic violence, the role played by Cameroon's legal system, and the struggles of LGBTI Cameroonians in their fight for a better life. The analysis includes a review of the work by scholars on colonialism and sexuality in Africa, and questions the roots of violence and abuse against the LGBTI community …

Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca

Master's Theses

This thesis focuses on the case study of Senegal to examine the implications of large- scale land acquisitions on the livelihoods of small-scale farmers. I investigate the diverse perspectives of market enthusiasts, human rights organizations, peasants, the state, and international financial organizations on large-scale land acquisitions. Based on primary research, I argue that the state of Senegal plays an active role in permitting “land grabs” and that they pose a threat to food sovereignty among Senegalese host communities. Lastly, I argue there needs to be a broader understanding of long-term consequences and risks to insure social justice in areas affected …

Between Mobility And Stability: Immigration, Free Trade, And Human Rights In The Context Of The Latino Immigrant, Joseph M. Stosberg

Master's Theses

This work takes a multi-dimensional approach to understanding human rights abuse toward Latino immigrants. It is argued here that the opening up of Mexico and Central American countries to free trade, and the restricted movement across borders has increased human rights abuse toward immigrants. In order to investigate these issues this research looks at: the opening up of Mexico and Central American countries to free trade; a pervasive narrative that portrays the Latino immigrant as a threat; and U.S. immigration policy. I use these respective bodies of literature to guide the discussion of the Latino immigrant experience, from the decision …

Social Marketing And California High-Speed Rail: A Framework For Behavioral Change Towards Sustainability, Spenser Dill

Master's Projects and Capstones

In this analytical paper, I advocate for the use of social marketing techniques in a campaign targeted towards Central Valley communities with the primary objective of reducing this population’s opposition to the state’s High-Speed Rail project. A secondary objective is to use this strategy to promote positive attitudes towards sustainable practices in general. The goal is to stimulate a change in regional culture, which will support the behavioral changes needed to protect California’s natural resources and reduce our state’s contribution to climate change. I argue: 1) creating a sustainable transit infrastructure with high-speed rail as its centerpiece will reduce harmful …

Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang

Master's Theses

Quorum sensing (QS) is a process of coordination of bacterial gene expression in response to cell population. System two QS is regulated by the small signaling molecule autoinducer-2 (AI-2) and is implicated in the infectious behaviors of various bacterial species. AI-2 is biosynthesized from S-ribosylhomocysteine (SRH) by the enzyme LuxS and induces interspecies cell-to-cell communication. Inhibition of LuxS would therefore inhibit interspecies QS. Herein, a search for novel molecular species that will competitively bind with SRH in the LuxS binding site is performed in silico. Computational screening results are then validated in vitro using an optimized LuxS inhibition …

Improving Lactose Digestion And Symptoms Of Lactose Intolerance With A Novel Galacto-Oligosaccharide (Rp-G28): A Randomized, Double-Blind Clinical Trial., Dennis Savaiano, Andrew J. Ritter, Todd R. Klaenhammer, Gareth M. James, Amy T. Longcore, Justin R. Chandler, W Allan Walker, Howard L. Foyt

Department of Nutrition Science Faculty Publications

Background

Lactose intolerance (LI) is a common medical problem with limited treatment options. The primary symptoms are abdominal pain, diarrhea, bloating, flatulence, and cramping. Limiting dairy foods to reduce symptoms contributes to low calcium intake and the risk for chronic disease. Adaptation of the colon bacteria to effectively metabolize lactose is a novel and potentially useful approach to improve lactose digestion and tolerance. RP-G28 is novel galacto-oligosaccharide (GOS) being investigated to improve lactose digestion and the symptoms of lactose intolerance in affected patients.

Methods

A randomized, double-blind, parallel group, placebo-controlled study was conducted at 2 sites in the United States. …

Mitochondrial Dysfunction And Reactive Oxygen Species In Neurodegeneration, Leah Farina

Honors Theses

Neurodegeneration leads to the loss of normal anatomy and physiology of the neuronal system in a human body. The hallmark of most neurodegenerative diseases is abnormal folding and accumulation of proteins within neuronal cell bodies that is not present in healthy people. These changes in normal protein metabolism often lead to neuronal cell death and failure of the affected regions of the central nervous system. Abnormal protein accumulation may be attributed to dysfunctional mitochondria and damage by reactive oxygen species. In addition to causing altered protein accumulation, dysfunctional mitochondria and an excess of reactive oxygen species also lead to errors …
