Influence Of Low Sonication Intensities At Different Temperatures On Acid Tolerance, Bile Tolerance, Protease Activity And Growth Of Yogurt Culture Bacteria Lactobacillus Delbrueckii Ssp. Bulgaricus And Streptococcus Salivarius Ssp. Thermophilus, Marvin L. Moncada Reyes

LSU Master's Theses

Streptococcus salivarius ssp. thermophilus and Lactobacillus delbrueckii ssp. bulgaricus are dairy cultures widely used in the dairy industry. Low sonication intensity condition is a non-destructive technique that uses sound waves to cause cavitation in aqueous solutions and may improve the permeability of membranes, speed up the transfer of substrates and promote cellular growth and propagation. The objective of this study was to determine the effect of low sonication intensities at different temperatures on acid tolerance, bile tolerance, protease activity and growth of the two dairy cultures. The cultures were freshly thawed and suspended in 0.1% peptone water and 18 ml …

Use Of Condensed Tannins Supplementation And Inorganic Copper As Deworming Agents In Naturally Infected Ewes And Lambs, Moara De Santana Martins

LSU Master's Theses

Sheep production is an important socioeconomic activity for the small producers and it can represent their primary income source. Gastrointestinal parasites have become the principal limiting factor for this industry around the world, especially because of the anthelmintic resistance phenomenon that has been increasing worldwide. The negligent use of anthelmintics has been reported as the main factor in the development of resistance. Among the parasites that infect sheep, H. contortus is considered the most harmful and also the parasite responsible for the fastest development of nematode resistance in small ruminants. Due to the economic impact this parasite may bring upon …

Aesthetics Of The Brink: Environmental Crisis And The Sublime In Mary Shelley's Frankenstein And Philip K. Dick's Do Androids Dream Of Electric Sheep?, Aaron Francis Schneeberger

Graduate Student Theses, Dissertations, & Professional Papers

Mary Shelley�s Frankenstein is today remembered as the progenitor of the science fiction genre, the first major literary work to link a long history of fictional narratives concerning the origins of life � notably drawing itself from the stories of Prometheus and Milton�s Paradise Lost � to the scientific rationalism of the enlightenment. Of the science fiction stories that would follow, Philip K. Dick�s Do Androids Dream of Electric Sheep? perhaps remains one of the closest to Shelley�s novel in terms of its concerns and themes. Dick�s text is concerned with the thematic of the creation of human simulacra, but …

Elizabeth Bishop's Photographic Poetics: The Peripheral Vision, Lise Lalonde

Graduate Student Theses, Dissertations, & Professional Papers

Elizabeth Bishop‘s poetics of description has been the object of numerous critical studies. These most often focus on questions of observation, positioning, framing, and refer to Bishop‘s aesthetics as ―optical poetics.‖ Instead of simply using optical vocabulary to talk about her work, I found that comparing her practice and the aesthetics of photography would help to illuminate our understanding of the restraint and yet strength of her work. This interdisciplinary approach allows me to answer very important questions: how does one make images with words? How does one palliate the inadequacies of the written word in the field of description? …

Literature Meets Biology: An Evolutionary Approach To Literary Studies, Samantha Reneé Dwyer

Graduate Student Theses, Dissertations, & Professional Papers

The following thesis engages with the relatively young development in literary studies, called evocriticism, which uses scientific perspectives to look at literature. It first gives an overview of the current state of English departments and their decline in numbers, budgets, and cultural relevancy, mostly due to outdated modes of literary criticism and theory. It then introduces evocriticism as a new paradigm for studying literature. Literature and the arts are studied as human behaviors with possible adaptive benefits. Individual texts are interpreted through a scientific lens, using the theory of evolution to find cultural and biological human universals that can help …

Graduate Student Theses, Dissertations, & Professional Papers

Unhinged by his inability to accept the fact that his son drowned a year ago, Fritz the Balloonatic, once the Southeast's preeminent balloon twister, has lost everything: his wife, his home, even his moniker. So now Fritz is living in a living room he has arranged in some South Carolina scrub woods, in a clearing that’s crowded with stuff that he has salvaged. His only plan for the future is to sell what he has accumulated someday, thereby raising enough money to get his life going again. But when Ransacked opens, Fritz’s effort is undermined: everything he has gathered and …

Efficacy Of Constructed Wetlands Of Various Depths For Natural Amphibian Community Conservation, Andrea Nicole Drayer

Online Theses and Dissertations

Wetlands provide critical habitat for a diverse group of amphibians and provide important ecosystem functions and services to humans. Despite this, most natural wetlands have been lost to land use practices. Consequently, constructing wetlands has become a common practice to mitigate for removed wetlands and to manage for wildlife. There were three primary objectives of this research: 1) to examine whether or not constructed wetlands located on ridge tops in eastern Kentucky in the Daniel Boone National Forest (DBNF) had amphibian communities comparable to natural ephemeral wetlands, 2) to examine amphibian predator-prey relationships within the constructed wetlands, and 3) to …

A direct analysis in real time mass spectrometry method was developed and validated for the analysis and quantitation of sugars that would be generated from pretreated and hydrolyzed switchgrass. This research aspect can be divided into two sections:

i) Literature Review: A review is presented on the status of energy security and how biomass and biofuels can be utilized as a source of transportation fuel. To this end, biomass (specifically switchgrass) can be broken down by pretreatment methods and then enzymatically hydrolyzed to simple sugars. These sugars can assist with algae growth that can eventually be converted into biofuels. …

Bat Species Diversity In Old-Growth Vs. Second Growth Forests In Lilley Cornett Woods, Letcher County, Kentucky, Lindsay R. Conley

Online Theses and Dissertations

Bat activity in old-growth forests (+150 years) is a subject that is poorly understood. The majority of old-growth forests are located in the northwestern portion of the United States, and with current silviculture practices, many forests are being cut. There have been no published studies that specifically examine bat use of old-growth forests in Kentucky. The objective of this study was to determine the diversity of bat species associated with old-growth and second growth forests within the Lilley Cornett Woods Appalachian Ecological Research Station, Letcher County, Kentucky. This study was conducted over 2 field seasons; 2009 and 2010. Mist netting …

Ultraviolet Reflectance Of Nestling Plumage And The Provisioning Strategies Of Adult Eastern Phoebes (Sayornis Phoebe), Alyssa Rae Underwood

Online Theses and Dissertations

Most songbirds are visually sensitive to ultraviolet (UV) wavelengths and, in some species, variation in the extent to which plumage reflects in the UV range provides information about individual quality that influences mate-choice decisions. Less is known about the possible importance of plumage UV reflectance in parent-offspring relationships. The lower breast and belly plumage of nestling Eastern Phoebes (Sayornis phoebe) reflects in the UV and adults may use variation in this reflectance to evaluate nestling quality and vary their provisioning behavior accordingly. To examine this possibility, I manipulated UV reflectance of nestling plumage by applying preen oil that …

Characterization Of Pregnancy Induced Cardiac Hypertrophy In Rats, Patricia Holden

Online Theses and Dissertations

During pregnancy, an increase in blood volume occurs to compensate for fetal development, resulting in cardiac hypertrophy. For the majority of women, this physiological cardiac hypertrophy resolves following pregnancy. Prolonged cardiac hypertrophy can lead to heart failure. We propose that by studying the biochemical mechanisms that mediate healthy cardiac remodeling associated with pregnancy, we will gain a better understanding of mechanisms involved in pathological cardiac hypertrophy. To determine the biochemical changes that occur during pregnancy induced cardiac remodeling, we subjected rats to timed matings and collected morphological and biochemical data from not pregnant, 19 days pregnant, and 24 hours postpartum. …

Reality Television And Its Impact On Women's Body Image, Ayarza Manwaring

Online Theses and Dissertations

Previous research has found that both print media and television may affect the body image of young women. Tiggerman and Pickering (1996) found that it was not just the amount of television viewed, but the viewing of appearance focused shows that affected body image. Schooler, Ward, Merriwether and Caruthers (2004) came to the conclusion that women's viewing of shows with predominantly white casts lead to greater body dissatisfaction. To date, no investigations have looked at a new and popular genre, categorized as, `reality television'. The purpose of this study was examine the effects of viewing this new genre and its …

Population And Conservation Genetics Of Crawfish Frogs, Lithobates Areolatus, At Their Northeastern Range Limits, Schyler O. Nunziata

Online Theses and Dissertations

Crawfish Frogs (Lithobates areolatus) are state endangered in Indiana and Iowa, with populations in decline throughout their range. I studied populations of Crawfish Frogs on local and statewide scales at their northeastern range limits to (1) assess the level of genetic diversity within populations (2) estimate fine-scale genetic structure, and (3) estimate genetic differentiation between populations at the state level. Crawfish Frogs breed in temporary pools and wetlands, and have high breeding-pond fidelity; therefore I predicted to find genetic differences between ponds at small geographic scales. I used 10 microsatellite loci to genotype frogs collected from three primary populations in …

Land Snail Species Diversity And Composition Between Different Forest Disturbance Regimes In Central And Eastern Kentucky Forests, Daniel Douglas

Online Theses and Dissertations

Land snails are cornerstone organisms that contribute to properly functioning ecosystems. However, habitat loss and destruction have led to these organisms being one of the most imperiled groups on the planet. Due to their relatively sedentary nature, land snails can be susceptible to anthropogenic disturbance and habitat fragmentation. Because of this, old-growth forests have the potential for being premiere habitat for these organisms, and snails have the potential to be good indicators of old-growth habitats. This study compared land snail species diversity and community composition in old-growth and second-growth forests in the Inner Bluegrass, Cumberland Plateau, and Pine Mountain ecoregions …

Effect Of Nestling Sex Ratio On The Provisioning Behavior Of Adult Eastern Bluebirds (Sialia Sialis), Barbara Ellen Kieffer

Online Theses and Dissertations

To maximize reproductive success, parents may, in some cases, differentially invest in sons and daughters, i.e., sex-biased parental investment. Preferential provisioning behavior has been reported in one population of Eastern Bluebirds (Sialia sialis) and attributed to local resource competition. To better understand this behavior, I studied the provisioning behavior of Eastern Bluebirds in Madison County, Kentucky, in 2004. I experimentally manipulated brood sex ratios in 24 bluebird nests, creating female-biased (N = 8), male-biased (N = 5), and control (N = 11) nests. Following manipulation, nests were video-taped to record adult provisioning behavior. Among experimental broods, the provisioning rates …

Online Theses and Dissertations

To focus on the need to improve literacy in rural Appalachia, this study investigates the use of Text Talk during read-aloud to increase the receptive vocabulary of participants. The investigator read six picturebooks to two groups of kindergarteners. Group A had 21 participants and Group B had 20 participants. Each group received instruction on two different sets of target vocabulary words, three in each book. The researcher administered a pre-test and post-test to each student patterned after the Peabody Picture Vocabulary Test. T-tests revealed that students made significant progress learning words when the reader used Text Talk during the lessons. …

Zapped: A Typology Of Use And Misuse Of The Taser, Lindsey L. Upton

Online Theses and Dissertations

Police use of TASER force is currently a hot topic of controversy in the intersections of society and the criminal justice system. Proponents, including manufacturers and law enforcement, value the TASER as a less than lethal alternative to deadly force; providing increased safety for officers as an aid to maintain distance between potentially threatening suspect(s) and officer(s) while preserving the life and well being of suspects in such encounters. Civil and human rights advocacies argue the TASER to be associated with many deaths, serious injury and abuse of power by law enforcement. Those who lean more toward the opposition of …

Stage-Specific Developmental Gene Expression Of Goat Preimplantation Embryos Produced In Vitro, Y. J. Li, H. Ao, G. J. Sun, L. Zhang

Turkish Journal of Veterinary & Animal Sciences

Single preimplantation embryo mRNA differential display was used to study the gene expression of 2-cell,4-cell, and 8-16-cell stage goat embryos produced in vitro, and 16 different stage specific bands in total were screened. In these specific bands, 5 were in 2-cell stage, 4 were in 4-cell stage, and 7 were in 8-16-cell stage, respectively. The sequencing and alignment results suggested that 4 differential expression bands were homologous with human petidylarginine deiminase (PAD), bovine insulin-like growth factor binding protein-3 (IGFBP3), bovine NADH dehydrogenase (ubiquinone) 1 alpha subcomplex 4 (NDUFA4), and dog cyclin B3 (CCNB3) genes, respectively. All these 4 genes had …
