The Incidence Of Antibiotic Resistance In Mesophilic Aeromonas Isolated From The Buffalo River And From A Non-Urban Site Upstream, Amy L. Chapman

Biology Theses

Antibiotics are commonly used in agriculture and industry and their discharge is commonly seen in rivers, like the Buffalo River. This antibiotic discharge may cause a selective environment which favors the growth of antibiotic resistant Aeromonas. To study the effect of urban pollution on the antibiotic resistance in Aeromonas, 229 Aeromonas isolates were collected from fish tissues as well as sediment and water samples collected from the Buffalo River and a non-urban site (Cazenovia Creek). Seven different Aeromonas taxa were identified using biochemical tests. There were 124 (54%) isolates that were classified as atypical, which was the most commonly …

Homing Behavior In Response To Displacement And Orientation Of The Northern Diamondback Terrapin (Malaclemys Terrapin Terrapin) In Barnegat Bay, New Jersey, Nicole M. Lainhart

Biology Theses

Increasing urbanization of the Barnegat Bayestuary in New Jersey has subjected northern diamondback terrapins to substantial habitat loss. Understanding whether terrapins have homing behavior, and determining the types of orientation cues they use to aid in this behavior, is important for conservation management. To test their homing behavior, nine non-gravid female terrapins were outfitted with biotelemetry tracking devices and data loggers and were displaced 4 km north and/or south. Eight of nine terrapins successfully returned home; the one terrapin that did not return home was inadvertently captured in a crab pot. Urbanization and shoreline development of the north displacement location …

Effect Of Vacuum Tumbling Time, Salt Level, And Phosphate Alternatives On Processing Characteristics Of Natural Deli-Style Turkey Breast, Derek J. Schroeder

Department of Animal Science: Dissertations, Theses, and Student Research

Three studies were conducted to determine the effect of vacuum tumbling time on the processing characteristics of reduced sodium natural deli-style turkey breast. Production of sodium reduced natural deli-style turkey breast without phosphate is lower (P <  0.05) in texture and processing properties than deli-style turkey breast produced with phosphate. Reducing salt concentration to 1.0% produces natural deli-style turkey breast with less acceptable (P <  0.05) texture and processing characteristics compared to 1.5% or 2.0% added salt. Preblending was used to improve texture characteristics in reduced salt products. Control treatments had improved (P <  0.05) texture properties, decreased color values, …

Ordinary Families: Queer Sexuality And Adoptive Parenthood In Central New York, Sean H. Wang

Theses - ALL

This thesis argues that geographers must consider sexuality and family together as integral parts of social life. Although sexuality already entered the lexicon of geography in the 1980s, and a burgeoning field of the geography of sexuality exists today, too often it is still considered peripheral in geographic scholarship. Similarly, family either remains consigned either as merely a place for social reproduction by studies of political economy, or is relegated entirely as an object of inquiry for only feminist geographers. Drawing from sociology, feminist and queer studies, this thesis makes an important intervention by relating sexuality and family in the …

Positioning An Innovative Flame-Weeding Technology Into Crop Production, Strahinja V. Stepanovic

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Propane flaming has a potential to be utilized for effective PRE and POST weed control in both organic and conventional farming systems. Field studies were conducted at the Haskell Agricultural Laboratory of the University of Nebraska in 2010, 2011, and 2012 to: (1) describe dose–response curves for propane when flaming selected weed species at different growth stages, (2) determine corn and soybean tolerance to single and repeated flaming by utilizing the equipment designed to selectively flame weeds in row crops with torches positioned parallel to the crop row, and (3) determine the effectiveness of flaming and cultivation for weed control …

Evaluation Of Oil Extraction On Corn Dry-Milling Byproducts In Growing And Finishing Cattle Diets, Melissa L. Jolly

Department of Animal Science: Dissertations, Theses, and Student Research

Dry-milling ethanol plants produce distillers grains (DG) and condensed distillers solubles (CDS). Before thin stillage is evaporated to CDS, corn oil is removed via centrifugation, producing de-oiled CDS. Depending on plant availability, CDS can be marketed or combined with DG to produce de-oiled distillers grains plus solubles (DGS). Currently, there are no data available on animal performance when corn oil is removed via centrifugation of the solubles stream. Therefore, two finishing experiments, a metabolism experiment, and a growing experiment were conducted to evaluate the effects of corn oil removal on cattle performance, carcass characteristics, and the effects on nutrient digestibility. …

Effects Of Maternal Nutrition And Post-Weaning Management In A Late Spring Calving System And Synchronization Of Estrus Using Fixed Time Ai Protocols, John D. Harms

Department of Animal Science: Dissertations, Theses, and Student Research

Three experiments were conducted to determine the impact of development systems, maternal protein supplementation, and estrus synchronization systems on beef cattle. Experiment 1 evaluated the effects of winter supplementation on cow performance and the effects of post-weaning management on progeny. Late spring calving cows grazed dormant range or meadow over winter and received either supplementation or no supplementation. Steer and heifer progeny were weaned and placed on dormant meadow or fed hay ad libitum. One half of the steers were placed in the feedlot at the end of treatment and the other half grazed range over summer. Cow winter treatment …

Transcriptional Regulation Of The Porcine Gnrh Receptor Gene By Glucocorticoids, Chanho Lee

Department of Animal Science: Dissertations, Theses, and Student Research

Binding of GnRH to its receptor (GnRHR) stimulates the synthesis and secretion of the gonadotropins, as well as up-regulation of GnRHR. Thus, the interaction between GnRH and GnRHR represents a central point for regulation of reproduction. Glucocorticoids alter reproduction by reducing GnRH responsiveness of gonadotropes within the anterior pituitary gland, potentially via transcriptional regulation of the GnRHR gene. Investigation into this mechanism, however, revealed that the murine GnRHR gene was stimulated by glucocorticoids. To determine the effect of glucocorticoids on porcine GnRHR gene expression, gonadotrope-derived αT3-1 cells were transiently transfected with a vector containing 5118 bp of 5’ flanking sequence …

Virotech Patents, Viropiracy, And Viral Sovereignty, Peter K. Yu

Faculty Scholarship

Although there are many important intellectual property and public health developments in the United States, the domestic debate remains surprisingly disconnected from the international debate. To help bridge this disconnect, this Article discusses the interrelationship between intellectual property and public health in the context of communicable diseases. This type of disease is intentionally picked to highlight how developments abroad could easily affect what happens at home, and vice versa.

The first half of this Article recounts three distinct stories about viruses responsible for AIDS, SARS, and the avian influenza (H5N1). The first story focuses on the ongoing developments within the …

Development Of Liriodendron Est-Ssr Markers And Genetic Composition Of Two Liriodendron Tulipifera L. Orchards, Xinfu Zhang

All Theses

Liriodendron tulipifera L., commonly known as yellow-poplar, is a fast-growing hardwood tree species with great ecological and economic value and is native to eastern North America. Liriodendron occupies an important phylogenetic position as a basal angiosperm and has been used in studies of the evolution of flowering plants. Genomic resources, such as Expressed Sequence Taq (EST) databases and Bacterial Artificial Chromosome (BAC) libraries, have been developed for this species. However, no genetic map is available for Liriodendron, and very few molecular markers have been developed. In this study, a total of 119 informative genomic SSR markers suitable were identified for …

A Study Of The Frothing Capacity Of Whole Milk- 1. A Market Survey Of Conventional And Organic Milks, 2. The Effect Of Clean In Place (Cip) Cleaning Solutions, Sara Stancil

All Theses

Gourmet coffee drink consumption is on the rise (NCAUSA 2013). With most of these coffee drinks including milk and/or milk foam, an emphasis on producing quality foam is of high importance. Recent complaints have been received on the failure of milk to foam to expectations of the coffee house (Randolph & Associates 2013). Identifying the source of this failure could enable the milk industry to provide higher foam quality milk to meet the growing needs of coffee houses.

A two-part study on the frothing capacity of milk was carried out to investigate potential variations in the market place and to …

Voluntary Exercise Can Strengthen The Circadian System In Aged Mice, T. L. Leise, Mary E. Harrington, P. C. Molyneux, I. Song, H. Queenan, E. Zimmerman, G. S. Lall, S. M. Biello

Psychology: Faculty Publications

Consistent daily rhythms are important to healthy aging according to studies linking disrupted circadian rhythms with negative health impacts. We studied the effects of age and exercise on baseline circadian rhythms and on the circadian system's ability to respond to the perturbation induced by an 8 h advance of the light:dark (LD) cycle as a test of the system's robustness. Mice (male, mPer2luc/C57BL/6) were studied at one of two ages: 3.5 months (n=39) and >18 months (n=72). We examined activity records of thesemice under entrained and shifted conditions as well as mPER2::LUC measures ex vivo to assess circadian function in …

Mutant Drought Phenotype Investigation : A Look Into Effects Of Protein Prenylation On Water Utilization In Conditions Of Varying Soil Saturation And Gene Knockout., Casey Rasmussen

College of Arts & Sciences Senior Theses

Plants respond to environmental stress, such as drought, with increases in levels of Abscisic Acid (ABA). This stress response allows greater survival rates but results in the plants producing lower seed yield and biomass. Certain mutant strains of the Arabidopsis plant have been identified with mutations in coding regions involved in the formation of the α and β subunits of PFT and PGGT-I genes involved in protein prenylation. We explored the possibility of these mutant strains to better preserve seed yield and plant biomass under drought stressing conditions in comparison to the wild type (Columbia) strain, based on the mutants’ …

Indira Gandhi: India’S Destined Leader, Josclyn C. Green

History Theses

This thesis explores the life and political career of Indira Nehru Gandhi and analyzes how the historical circumstances of her era shaped her character in a manner that made her uniquely prepared to confront the numerous political challenges that she faced during her tenure as India’s Prime Minister. Indira Nehru Gandhi was Prime Minister of India from 1966 until 1977, and again in 1980 up until her assassination in 1984. Indira Gandhi was seemingly destined to rule over India. She was born into a prominent family who led the way to Indian independence from Great Britain. She was also born …

Second Nature: An Exploration In Planning And Design For A Place- And Community-Based Museum Process, Erin E. Hicks

Museum Studies Projects

Museums are and have been engaged in a paradigm shift. Much has been written about the social roles of museums and many in the field have sought to define museums, taking a position on why the museum exists, who it is for, and why it continues. Is the museum a temple or a forum? I wondered why it could not be both— and more—more inclusionary, more participatory, and more reflective of community. Could this be the museum of the future? This project explores how a museum transforms both physically and theoretically by applying an educational mission onto a hypothetical museum: …

The Separate And Combined Effects Of Heredity And Environment Predicting Alcohol Use Disorder Symptoms And Antisocial Personality Disorder Symptoms, Jaylee R. Gill

Honors Theses

The current study examined genetic and environmental influences in relation to alcohol use pathology. The 756 participants (378 adoptive, 378 non-adoptive) came from the 2001-2002 NESARC conducted by the NIAAA. A factorial ANOVA was used to measure the effects that the three grouping variables had on each dependent variable for a total of seven datasets. Results showed that biological parents’ drinking did pose a risk in participants for Loss of Control (p = .000) and Dangerous Behavior (p = .00). Adoption status was correlated with Conduct Disorder (p = .007) and Antisocial Personality Disorder (p = .014). This suggests that …

Contextual Expectations Of Privacy, Andrew D. Selbst

Cardozo Law Review

Fourth Amendment search jurisprudence is nominally based on a "reasonable expectation of privacy," but actual doctrine is disconnected from society's conception of privacy. Courts rely on various binary distinctions: Is a piece of information secret or not? Was the observed conduct inside or outside? While often convenient, none of these binary distinctions can adequately capture the complicated range of ideas encompassed by "privacy." Privacy theorists have begun to understand that a consideration of social context is essential to a full understanding of privacy. Helen Nissenbaum's theory of contextual integrity, which characterizes a right to privacy as the preservation of expected …

Seasonal And Diurnal Behavioral Patterns Of Bottlenose Dolphins, Tursiops Truncatus, That Exhibit High Site And Low Site Fidelity To Mississippi Sound, Shauna Marisa Mcbride

Master's Theses

This study examined whether bottlenose dolphins (Tursiops truncatus) exhibit site fidelity to the Mississippi Sound and how the seasonal and diurnal behavioral patterns of dolphins that exhibit high site fidelity to the Mississippi Sound differ from those of dolphins with lower site fidelity. Opportunistic surveys conducted from July 2006 to April 2010 were analyzed. Statistical analyses consisted of nonparametric tests (Spearman's correlation, loglinear models, and Pearson's chi-square) to compare behavioral patterns of high site fidelity, mixed, and low site fidelity groups. Behavioral patterns significantly differed between site fidelity groups across seasons and diurnal periods. Feeding behavior was observed significantly more …

Stimulant Use, Associated Psychopathology, And Eating Disordered Symptomatology, Tiffany Ann Hopkins

Master's Theses

The current study developed profiles of eating disorder, personality, and other psychopathological symptoms related to the use of central nervous system stimulants versus other types of drug use. Participants included 124 women in residential treatment for substance use with and without comorbid eating disorders. Symptomatology was measured by the Eating Disorders lnventory-3 (EDI-3), Millon Multiaxial Inventory-III (MCMI-III), and Personality Assessment Inventory (PAl). The current study utilized a series of six multivariate analyses of variance (MANOVAs) and discriminant analyses to determine patterns of psychopathology separating stimulant use from other drug use. Results indicated that women who used stimulants were primarily separated …

Narratives By Six Year Old And Nine Year Old Boys: Brute: Institutional, And Non-Institutional Mental Facts, Adam Craig Whipple

Master's Theses

Brute facts, institutional facts, and non-institutional mental facts were studied. The philosophy of constructionism and the theory of intent provided a framework for this research. Intentionality provided the basis for social facts. Brute, institutional, and noninstitutional mental facts were operationally defined. This study analyzed the use of these facts in the narratives of 6-year-old boys and 9-year-old boys. There were a total of 19 participants in this research. This research established brute, institutional, and non-institutional mental facts as appropriate operational categories for studying children's narratives. The 6-year-old boys produced more brute facts than the 9-year-old boys. The 9-year-old boys produced …

Using the Middle School Environmental Literacy Survey, 6th grade students across Arkansas were surveyed to obtain a baseline measure of environmental literacy based on the four domains of environmental literacy included in the survey; ecological knowledge, environmental affect, cognitive skills, and behavior. Individual domain scores were combined into a composite environmental literacy score. Results were then compared to the …

Identification Of Biomarkers Associated With Ascites Incidence In Broilers, Kaylee Rowland

Graduate Theses and Dissertations

Poultry is key in genetic research due to breeding feasibility, relatively short generation interval, and distinct phenotypes. It is estimated that 8% of broiler deaths annually can be attributed to ascites, an economically important disease that has been challenging the industry for the past 2 decades. Genetically selected ascites resistant (RES) and susceptible (SUS) chicken lines have been established and maintained by the University of Arkansas, Fayetteville. Intensive research efforts have been made to reveal physiological and biochemical characteristics for the incidence of ascites. Since the whole genome of the major ancestral chicken, the Red Jungle Fowl, has been sequenced, …

Effect Of Modified Starch On Bake-Only Chicken Nuggets, Sarah Purcell

Graduate Theses and Dissertations

The food industry has become increasingly focused on healthier items. Fried foods especially are actively pursuing non-fried alternatives to attract health conscience consumers. This study investigated the bake-only chicken nugget formulation in attempts to provide characteristics of fried items. Starch was hydrolyzed by amyloglucosidase to create a porous structure that had the ability to absorb oil. Oil was plated into the enzyme-treated starch and blended into nugget formulation, and the coated nuggets were steam-baked until fully cooked. The enzyme-treated starches showed a decrease in gelatinization range and pasting viscosities for all starch types. The addition of oil-plated enzyme modified starch …
