Investigating The Potential Of Microbial Metabolites And Mtor Signaling On Chicken Necrotic Enteritis, Mohit Bansal Dec 2020

Investigating The Potential Of Microbial Metabolites And Mtor Signaling On Chicken Necrotic Enteritis, Mohit Bansal

Graduate Theses and Dissertations

Necrotic enteritis (NE), caused by C. perfringens and coccidiosis, is responsible for substantial economic loss annually. In the first chapter, we investigated the effect of secondary bile acid on necrotic enteritis. Day-old broiler chicks were randomly assigned to 5 groups of diets supplemented with 0 (basal diet), 0.8, 1.0, and 1.5 g/kg (on top of basal diet) deoxycholic acid (DCA). The birds were challenged with Eimeria maxima (20,000 oocysts/bird) at d 18 and C. perfringens (109CFU/bird/day) at d 23 and d 24 to induce NE. Birds were sacrificed at d 26, and ileal tissue and digesta samples were collected. DCA …


The Surveillance Of Gastrointestinal Parasitic Nematodes Of Northwest Arkansas Dairy Cattle Using Traditional And Genetic Parasitological Identification Procedures, Eva M. Wray Dec 2020

The Surveillance Of Gastrointestinal Parasitic Nematodes Of Northwest Arkansas Dairy Cattle Using Traditional And Genetic Parasitological Identification Procedures, Eva M. Wray

Graduate Theses and Dissertations

Traditional and genetic parasitological identification procedures were compared using naturaland artificial nematode parasite infections in Holstein steer calves. The traditional parasitological procedures measured fecal egg counts, coprocultures with subsequent larval collection and adult nematodes collected at necropsy. The genetic identification procedures measured ITS-2 sequences extracted from different stages of nematode development: raw feces, concentrated nematode eggs, third stage larvae and adults. The primary nematodes observed were Cooperia oncophora, Cooperia punctata and Ostertagia ostertagi. The traditional techniques were not significantly different from one another, while the genetic sequencing showed variation amongst the different procedures. The raw feces sequences showed the most …


The Effects Of Solution Condition On Virus Filtration Performance, Fnu Namila Dec 2020

The Effects Of Solution Condition On Virus Filtration Performance, Fnu Namila

Graduate Theses and Dissertations

Virus filtration is an integral part of the downstream purification of mammalian cell culture-derived biotherapeutics to assure the viral safety of the products. Virus filtration membranes remove viruses based on a size-exclusion mechanism. Commercial parvovirus filers possess unique membrane structure and are designed to remove smaller non-enveloped parvoviruses with size 18-26 nm. However, some filters face issues, such as pre-mature fouling, the decline of filtrate flux, and reduction in virus retention. This doctoral dissertation focused on identifying the factors that influence the filtrate flux and the virus retention capability of commercial virus filters. The effects of solution pH and ionic …

Purchased, Becky Retz

LSU New Orleans Theses and Dissertations

A play in two acts, Purchased tells the story of Francois DeLord and his journey from being a French Creole of New Orleans to becoming a Black man in America. In 1803, Napoleon sold France’s North American holdings to the United States in what became known as the Louisiana Purchase. Americans flooded into the city, bringing with them boatloads of money and a social philosophy that clashed with long-held local traditions. The sale doubled the size of the young nation, and ignited a culture war in New Orleans,

Analysis Of Mothers’ Parenting Consistency: Associations With Children’S Adjustment, David R L Brabham

LSU New Orleans Theses and Dissertations

While robust literature exists on the association between positive and negative parenting with child outcomes, less is known about the nature of parenting’s consistency in this relationship. This study sought to examine the relationship between valence and consistency of parenting, and to determine whether consistency is associated with child adjustment independent of valence. Data were collected from 167 mothers and their toddler-aged child. Participation involved two time points, 1 year apart. At each time point, mothers’ observational data were obtained via videotape of designed interactions between mother and toddler, as well as survey data from mothers. Bivariate correlations and multiple …

Design And Synthesis Of Novel No-Drug Hybrid Compound And Green Catalytic Activity Evaluation Of Synthesized Silver Nanoparticles-Halloysite Nanocomposite, Majed Abdullah Bajaber

LSU New Orleans Theses and Dissertations

Acetaminophen is a well-known analgesic that can manage pain and reduce fever. SCP-1 is a derivative of acetaminophen that showed significantly reduced hepatotoxicity and nephrotoxicity comparative to acetaminophen. Nitric oxides have been well known to play a key role in a wide variety of physiological and pathophysiological important processes. It was therefore of interest to synthesize a nitric oxide donor linked to SCP-1 that could have enhanced analgesic and antipyretic activity. A furoxan CAS 1609 as NO-donor was synthesized and linked to SCP-1 successfully. The furoxan CAS 1609 was initially synthesized from tetronic acid to give 1,2- dioxime in 86 …


A Phenomenological Study Of Emotion Amid Significant Organizational Change, Ian Menchini Dec 2020

A Phenomenological Study Of Emotion Amid Significant Organizational Change, Ian Menchini

All Theses And Dissertations

This study employed a phenomenological methodology to explore the experiences shared by leaders of a public university in the Northeast United States during an extraordinary period of organizational change. The university’s organizational transformation was particularly noteworthy because it came in the face of circumstances entirely out of the university’s control. These circumstances included its state’s declining population as well as its state government’s failure to invest heavily in higher education. These long-term challenges were exacerbated by the sudden onset of the Covid-19 pandemic and a near simultaneous proposal by its system’s former executive to radically and negatively change the university’s …


“9/11 And The Collapse Of The American Dream: Imbolo Mbue’S Behold The Dreamers”, Elizabeth Toohey Dec 2020

“9/11 And The Collapse Of The American Dream: Imbolo Mbue’S Behold The Dreamers”, Elizabeth Toohey

Publications and Research

Behold the Dreamers follows a Cameroonian couple who, as newcomers to America, harbor dreams of success unavailable to them back home. Undocumented immigration, the widening gulf between rich and poor, and the thinly veiled racism of an avowedly "post-racial" culture converge in this new generation of immigrants' painful encounter with the American dream. I consider the ways Mbue's novel shares themes with a "second wave" of post- 9/11 literature—first, in centering the disillusionment of a protagonist aspiring to the American dream; next, in its representation of New York as a space haunted by 9/11, but also of resistance to the …

Assessing And Responding To Covid-19 Pandemic Nutrition And Wellness Impacts On Iowans, Morgan Bahl, Sarah L. Francis, Ruth Litchfield, Shannon Coleman, Anirudh Naig

Journal of Extension

The COVID-19 pandemic has increased the need for indirect Extension programming. To ensure a consumer-focused response, we gathered data from 452 survey respondents regarding how the pandemic was affecting their food-related and health behaviors. The majority reported obtaining their food from a grocery store as they had prior to the pandemic, albeit less frequently, and having increased their home food preparation. Due to the pandemic, respondents were less physically active and more stressed and were seeking reliable nutrition and wellness information. We describe how we were able to facilitate an immediate response by repackaging and adapting existing programming to meet …


Comparing Linkages Between Descriptive Norms And Current And Intended Outdoor Water Conservation, Laura A. Warner, Savanna Turner, Lisa Lundy Dec 2020

Comparing Linkages Between Descriptive Norms And Current And Intended Outdoor Water Conservation, Laura A. Warner, Savanna Turner, Lisa Lundy

Journal of Extension

The study presented here was used for evaluating how theory of planned behavior variables (attitude, perceived behavioral control, subjective norms) and perceptions of others' outdoor water conservation (descriptive norms) related to individuals' own conservation and intent to conserve. The theory of planned behavior predicted current and intended conservation similarly. Descriptive norms from close-peer and state referent groups improved predictions of current practices but not behavioral intentions. Descriptive norms may be more influential when Extension clients are establishing routines pertaining to outdoor water conservation (e.g., installing a new landscape). Extension professionals should strategically communicate a conservation norm at similar opportune times.

Social Media Use For Farmers Market Communications In Illinois, Dandan Tao, Taylor Kathryne Ruth, Janie Maxwell, Hao Feng

Journal of Extension

Social media has been recognized as a powerful tool supporting communication of many topics in the agriculture industry. We explored the use of social media platforms among farmers market managers and specialty crop growers in Illinois through an online survey. Facebook, Instagram, and Twitter were platforms used by the majority of respondents. We found that social media was used primarily for communicating with consumers for marketing purposes. We identified major training needs of farmers market stakeholders related to using social media to promote business and convey food safety information.

Otolith Age Validation And Microchemical Investigation Of The Northern Stock F Atlantic Black Sea Bass (Centropristis Striata), Elise R. Koob Dec 2020

Otolith Age Validation And Microchemical Investigation Of The Northern Stock F Atlantic Black Sea Bass (Centropristis Striata), Elise R. Koob

Graduate Masters Theses

Black sea bass (Centropristis striata) is a demersal marine species that supports extensive commercial and recreational fisheries along the Atlantic coast. A recent expansion into the Gulf of Maine raises questions about this species’ movement and population dynamics in the region. Additionally, the 2016 catch-at-age stock assessment model for the northern stock incorporated a population split at the Hudson Canyon. Though this model better accounts for differences in populations, several issues remain. First, validation of the otolith ageing technique for this stock is incomplete; and, second, the origin of fish that moved into the northern ranges of the Gulf of …

Teacher Perceptions Of Collegial Collaboration In An Academy Structure., Kristy Marie Field

Electronic Theses and Dissertations

Collaboration in is an often researched, many-named concept with a definition which has historically been unclear. What one calls collegiality another may call teacher teaming and yet another may refer to as professional networking. Scholars agree effective teacher collaboration can lead to higher student achievement, teacher efficacy, and teacher retention. However, as elusive as an agreed-upon definition may be an agreed-upon structure that fosters an effective version of this collaboration. When Ford began the Ford Next Generation Learning initiative, they embarked on the path to developing a school model that focused on school and community partnerships to support long-term, transformational …

I Told You That To Tell You This: Metagaming And Metacognition In The Hybrid Classroom, Marc A. Ouellette Dec 2020

I Told You That To Tell You This: Metagaming And Metacognition In The Hybrid Classroom, Marc A. Ouellette

English Faculty Publications

This paper theorizes the use of play and gamified methods to foster metacognition, or strategies for learning and learning about learning, in online graduate instruction. In the process, it calls into question the determinism of “serious” games as being the only means of facilitating metacognition. Ultimately, by adopting metagame approaches—that is, approaches based on0 goals and achievements that are external to the game and/or are developed by the players themselves—metacognition can and does occur because students participate in the development of the rewards. Moreover, any metagame feature ultimately becomes a commentary so that an approach based on metagaming offers its …
