Supply Chain Optimization Of Blood Products, Serkan Gunpinar

USF Tampa Graduate Theses and Dissertations

Major challenges in the management of blood supply chain are related to the shortage and wastage of the blood products. Given the perishability characteristics of blood which can be stored up to a limited number of days, if hospitals and blood centers keep an excessive number of blood units on inventory, wastages may occur. On the other hand, if sufficient number of blood units are not stored on inventory, shortages of this resource may cause the cancellations of important activities and increase the fatality rates at hospitals. Three mathematical models have been developed with the goal to improve the efficiency …

Implications for future research are discussed.

The Grotesque Museum In Dickens’ Great Expectations, Ehsan Hafezikermani, Roshanak Fazli

Khazar Journal of Humanities and Social Sciences

This novel is Dickens' thirteenth novel and was first printed in the weekly magazine All The Year Round in 1860 (GE Introduction, v). It is a Bildungsroman and its characters are developing through the story. So, Dickens, from the beginning, uses Pip as his camera to display almost everything using grotesquery elements in the novel. Pip makes different mental pictures in the story about most of the things, and it shows that he is changing his mind as he is growing up. So, the idea of grotesquery is evolving too; for instance, ideas of Pip about Magwitch are changed from …

Conceptual Dissonance Between Thoreau's And Wordsworth's View On Nature And Imagination, Mahshad Jalalpourroodsari

Khazar Journal of Humanities and Social Sciences

Henry David Thoreau (1817-1862) and William Wordsworth (1770-1850) belong to two different sects. The former is a Transcendentalist or a member of American Romanticism with its unifying account of self and nature, and the latter is an English Romantic poet belonging to a group of poets called the "lake School [or] the lakers" (Ruston 90-91) who were involved in the appreciation of and dissolution in their natural surroundings. Despite the fact that these two figures have much in common, there are points and junctures where they diverge in their perspectives towards the essential grounds of their parallel philosophies. Through having …

Alpha-Synuclein Aggregates Activate The Nlrp3 Inflammasome Following Vesicle Rupture, Rudy Orlando Cedillos

Master's Theses

Parkinson's disease (PD) and related synucleinopathies are progressive neurodegenerative disorders that feature the accumulation of intracellular inclusions known as Lewy bodies (LBs) in the brain. The presynaptic protein α-synuclein is the primary constituent of LBs and has been documented to play a major role in the pathogenesis of synucleinopathies. Recently, aggregated α-synuclein has been implicated in prompting microglia-mediated inflammation, a process associated with the progression of neuronal death in neurodegenerative disorders. Although the mechanisms surrounding the induction of neuroinflammation are not well understood, the recently discovered inflammasome-forming NLR proteins have emerged as regulators of inflammation. In this study, we sought …

Evidence For Renewal And Reconstitution Of Marginal Zone Macrophages In Young And Aged Mice, Erika Bahamon

Master's Theses

Aging in humans and mice correlates with decline in immune health, affecting both innate and adaptive immunity. Response against blood-borne bacterial pathogens is compromised because of the deterioration of the marginal zones of the spleen and decrease in frequency of marginal zone macrophages (MZM). This thesis asked if low cell turnover is the cause for the decrease of MZM, using cell proliferation to indicate cell turnover in spleens of mice. First, evidence showed MZM proliferation occurred in spleens of young mice and was decreased in the MZM from aged mice. Second, transfer of young bone marrow into old mice replenished …

Aquatic Macroinvertebrate Response To Invasion And Subsequent Removal Of Typha × Glauca From Great Lakes Coastal Marshes, Kimberly Anne Greene

Master's Theses

Aquatic macroinvertebrates are important in wetland ecosystems; many fish and wildlife species depend upon them for food resources and they aid in nutrient cycling. Wetland macroinvertebrate communities are influenced by plant community composition; as such, this study examined two implications of invasive hybrid cattail, Typha × glauca (Typha), on aquatic macroinvertebrate communities in northern Great Lakes coastal wetlands: 1) how the presence of nearly monotypic stands of Typha alters wetland aquatic macroinvertebrate communities and 2) how manual removal of Typha, via mowing and manual tilling, impacts these invertebrate communities along with wetland plant communities. I found that …

Activity Patterns And Spatial Resource Selection Of The Eastern Garter Snake (Thamnophis Sirtalis Sirtalis), Matthew Gregory Most

Master's Theses

Snake species usually exhibit seasonal variations in activity patterns, home-range size and the use of respective habitat. Using mark-recapture protocols I marked 96 individual Thamnophis sirtalis sirtalis specimens in Lake Forest, IL to determine the independent variables that best explained habitat selection in a population of Eastern Garter Snakes (T. s. sirtalis). Specifically, I focused on the relationship between seasonal movement and home range size of male and female garter snakes. I analyzed the habitat preferences and spatial ecology of Eastern Garter Snakes during the 2011 sampling season and modeled the relationship between preferred or avoided habitat, in conjunction with …

Selective Expansion Of B Cells By Intestinal Microbiota, Karina Ochoa

Master's Theses

In rabbits, antibody diversity and B cell expansion are generated in gut-associated lymphoid tissues (GALT), in an antigen- and T cell-independent mechanism, and require interaction with intestinal microbiota. I investigated, in vitro, the mechanism by which commensals drive GALT reactions. Bacteria were isolated from the GALT of rabbits and identified by 16sRNA sequencing. I found that the commensals can bind to Ig, independently of their specificity. In addition, a ~20kDa bacterial molecule was immunoprecipitated with recombinant Ig molecules. Stimulation of B cells with selected bacterial molecules induced the activation of B cells. Stimulation of B cells through TLR2 induced the …

Assessing The Effects Of Titanium Dioxide Nanoparticles On Microbial Communities In Stream Sediment Using Artificial Streams And High Throughput Screening, Alexandra Ozaki

Master's Theses

Nano-titanium dioxide (nano-TiO2) is an engineered nanomaterial used in a wide array of commercial products. The production and use of large amounts of nano-TiO2 is resulting in the unintended release to the environment. Nano-TiO2 is known to be cytotoxic due primarily to its ability to generate reactive oxygen species, and negative impacts on a variety of organisms have been demonstrated, but the effects of nano-TiO2 on complex microbial communities under ecologically relevant conditions have rarely been tested. We conducted a controlled manipulative experiment using recirculating model streams dosed with a one-time amendment of 1mg L-1 nano-TiO2 (specifically P25). Within one …

Antibodies To Inhibit Clostridium Difficile Adhesion To Human Gut Epithelial Cell Line, Wonbeom Paik

Master's Theses

Clostridium difficile infection (CDI) is a major hospital-acquired diarrhea that can cause life-threatening complications such as pseudomembranous colitis. CDI is caused by colonization of host with C. difficile, a Gram positive, anaerobic bacterium known to produce toxins that cause disease. Normally, the gut microbiota protects the host from CDI, but disruption of the microbial composition through antibiotic treatment can leave one vulnerable for CDI. To date, no vaccines for preventing CDI are available.

In this study, the potential of antibodies directed against specific surface molecules of C. difficile to block bacterial adherence to host gut epithelial cells was studied, in …

SOLON Law, Crime and History (previously SOLON Crimes and Misdemeanours: Deviance and the Law in Historical Perspective)

Scholars have acknowledged that the study of World War II era intelligence can be an extremely arduous undertaking. Intelligence tradecraft, by its very nature, requires that certain information remain secret. It necessitates the sustained concealment of activities or events. Moreover, this government emphasis on secrecy often results in the suppression of sensitive information from historians and citizens alike. Thus, one must turn to declassified records of the past to reshape modern conceptions of history. This article should be regarded as a spirited departure from traditional scholarship. Specifically, it utilizes the case study method to communicate a powerful message related to …

The Unmanly Fear: Extortion Before The Twentieth Century, Joseph S. Bonica

SOLON Law, Crime and History (previously SOLON Crimes and Misdemeanours: Deviance and the Law in Historical Perspective)

This essay concerns the history of extortion in American law and culture, highlighting the shift from extortion as a paradigmatically male enterprise to one inseparably associated with women. Before the nineteenth-century, extortion was figured as an assault on a victim’s consent. Since men monopolized consent, extortion unfolded as a contest between legal subjects over political manhood. After the mid-nineteenth-century, a new class of ‘respectable’ victims, openly terrified by women’s threats, made unprecedented claims for legal protection. In response, well-placed courts wrote consent out of the equation, broadening the scope of extortionous threats to unleash the familiar fin-de-siècle tide of sex …

A Reassessment Of The Conservation Status Of A Critically Endangered Neotropical Frog, Mannophryne Olmonae, Using Occupancy Modeling Techniques, Jessica Mcquigg

Senior Independent Study Theses

Amphibian species worldwide are threatened with decline and extinction, making species monitoring an important scientific endeavor. The Bloody Bay Poison Frog, Mannophryne olmonae, a Tobago island endemic, was identified as critically endangered by the IUCN in 2004. Recent evidence suggests that a less severe conservation status may be appropriate for M. olmonae. This study employs acoustic calling surveys, land-use information, and multi-year (2011 and 2012) occupancy modeling techniques to propose an appropriate conservation status for this species. This study suggests that M. olmonae occupies a larger geographic range than was previously thought, and is not experiencing population declines. …

The Postmodern Shift In Library Instruction, Terry Dwain Robertson

Faculty Publications

Fifty years ago, prior to the digital revolution, library instruction consisted of a knowledgeable librarian guiding students through the various classes of documents, with examples of recognized authorities. Each bibliographic tool was handcrafted by competent individuals, published by reputable publishers, and recommended by disciplinary practitioners. While working through these various tools was time consuming, and getting access to materials not held locally often proved slow, the student researcher could reasonably assume the sincerity and integrity of the sources. With the digital revolution, much has changed. Now, instead of bibliographic instruction, librarians engage in “information literacy”(IL) training. Rather than point students …

Vocabulary Instruction : Becoming Word Conscious To Support Reading Comprehension, Amy Evelyn Bries

Graduate Research Papers

Currently, many classroom teachers are striving to support students' comprehension skills. Teachers are currently teaching vocabulary through incidental exposures. The dependency of vocabulary skills are falling to the students. The students might be asked to memorize rather than gathering a deeper meaning of a word and how we use the word within context. Over the past several years research has shown that vocabulary develops more rapidly after grade three, but the primary grades need to begin with a strong literacy foundation in word learning strategies (Biemiller, 2003, 2006). This research project organized professional development sessions for teachers, to provide the …

Portrayal Of Agriculture In Children's Literature: Contemporary Stories In Picture Books, Traditional Tales, And Nonfiction, Kathryn S. Koller

Graduate Research Papers

The purpose of this research was to analyze the representations of modern American farming in traditional tales in picture book format, storybooks with contemporary settings, and non-fiction literature to assess how accurately agriculture information is provided to children. This project will contribute to the knowledge base about how well children’s books are compensating for the lack of first-hand experience. The four hypothesizes studied were: 1. Ninety percent of storybooks with contemporary settings will depict a male in the role of farmer. 2. One hundred percent of traditional literature in picture book format will depict a farmer wearing bib overalls, straw …

Graduate Research Papers

The purpose of this study was to examine the Iowa Children's Choice Award lists for variety of reading levels, topics, and protagonists and compare this to the criteria set by the Iowa Association of School Librarians. A quantitative content analysis was conducted to allow comparison between the last four years of Iowa Children's Choice Award lists. Results showed that all of the texts chosen for the award lists in the last four years fell in the third through sixth grade level according to Fountas and Pinnell. The majority of the texts include a female protagonist making the award lists more …

What Are The Mechanisms Of Action Of Stereotype Threat And How Does It Contribute To The Development Of Cardiovascular Disease In African Americans, Anthony Gage

Graduate Research Papers

The rate of hypertension and cardiovascular disease for African Americans is disproportionately higher compared to Whites Americans. Previous research has focused much of its attention on biological and socioeconomic differences as a pathway to explain the disparity in rates of cardiovascular disease. Reviewed is the connection between socioeconomic status and cardiovascular disease, but also extends the reach of etiology to include racially induced cardiovascular reactivity responses in African American. Stereotype threat occurs when a member of a stereotyped group encounters a situation where a stereotype exists, the threat of confirming the stereotype produces an exaggerated cardiovascular response. This model takes …

The Isolation And Characterisation Of Acientobacter Baumannii Bacteriophage, Mohamed Farag M. Elbreki

Theses

Acinetobacter baumannii is a pathogen, which has an increasing prevalence of multidrug resistance. It exists widely in natural environments, and frequently in health-care settings where it has proven difficult to eradicate using antibiotic therapy. A possible alternative to conventional antibiotics is the use of bacteriophages (phages) as antibacterials. In this project, extensive screening of environmental samples such as soils, sewage and waters was undertaken to identify suitable phages. Three phages were successfully isolated from municipal waste in the Cork area. These were subsequently characterized in detail and examined by electron microscopy, which showed that they were all of the Myoviridae …
