A Quantitative Analysis Of Morphological Changes In Specific Laminae Of The Olfactory Bulb Of Adult Zebrafish Following Peripheral Sensory Deafferentation, Travis L. Devlin

Masters Theses

Permanent removal of the olfactory organ in adult zebrafish has been shown to result in a significant reduction in the total volume of the ipsilateral olfactory bulb. The overall objective of the current project was to investigate the hypothesis that contact between the axons of the olfactory sensory neurons and the olfactory bulb is necessary for the maintenance of the normal post-synaptic organization of the olfactory bulb by quantifying the morphological changes that take place within specific laminae of the olfactory bulb following peripheral deafferentation. Complete, unilateral ablation of the olfactory organ resulted in permanent deafferentation of the ipsilateral olfactory …

Expression And Characterization Of Hyperthermophilic Aqujfex Pyrophilus Flagellin Protein In Mesophilic Bacterial Systems, Srivani V. Mukkamala

Masters Theses

The structural protein flagellin, FlaA derived from hyperthermophilic Aquifex pyrophilus, a rod shaped eubacterial species that grows near hydrothermal vents at an optimum growth temperature of 85 °C forms elongated thermostable flagella nanotubes. FlaA was successfully over-expressed for the first time using pET28c plasmid in E. coli BL21 cells at 37 °C. The protein was isolated from inclusion bodies that were solubilized by alkaline pH, refolded by dialysis and purified by chromatographic techniques. The FlaA was characterized by fluorescence, light scattering and circular dichroism. The FlaA was not in the correct folded form to form flagella as efforts to …

A Statistical Analysis Of The Distribution Of Roads Salt In Blueberry Farm Soils Of Van Buren County, Michigan, Melissa M. Kovach

Masters Theses

The purpose of this research is to compare and analyze the leaching of road salt (sodium chloride) in soils of blueberry farms. Due to recent events in Ottawa County, Michigan, road salt is increasingly being blamed for blueberry production loss. Sodium chloride is harmful because once a significant amount of salt enters the soil profile the salt is unable to be flushed out, and reduces the chance for nutrients to reach the plant for effective growth. This study tested the farms' soils for salinity before winter (October 2005), during winter (March 2006) and after winter (May 2006) to determine if …

Investigation Of Knock In Gaseous Fuels In The Presence Of Diluents, Roshan Ashok Rodrigues

Masters Theses

Recent energy security and environmental concerns have prompted growing interest into utilization of alternative fuels such as, natural gas and landfill gas. These gaseous fuels contain significant amount of diluents in the fuel composition, such as carbon dioxide, nitrogen, water vapor and other trace gases, which vary by geographical location. Successful engine operation is limited by a phenomenon called "knock", which occurs due to auto-ignition of the end gas ahead of the flame front, and therefore, needs to be investigated with the utilization of these gaseous fuels.

The present contribution discusses the experimental set-up, procedure and results of the investigation …

Training Parents To Treat Noncompliance In Children With Developmental Disabilities Using Guided Compliance, Christine Bennett

Masters Theses

Noncompliance with parental directions is a critical target for children with developmental disabilities for several reasons, including the frequency of the problem and its impact on caregivers. Three decades of research have shown the effectiveness of guided compliance with children with developmental disabilities; however, only a few studies have examined the effects of parent-implemented guided compliance with this population (Handen, Parrish, McClung, Kerwin, & Evans, 1992; Smith & Lerman, 1999; Tarbox, Wallace, & Penrod, 2003). Three children with developmental disabilities and one primary caregiver for each participated in the present study. Parents were trained in three-step guided compliance (i.e., command, …

Tic: Term Intersection Clustering Of Text Documents, Casey R. Bartman

Masters Theses

Preliminary work performed by the author [3] investigated the clustering of text documents based upon the Boolean intersection of document term sets. In that algorithm, documents were associated with terms and the resulting sets of terms were intersected. If the intersection of the sets produced a set equal to or larger than a predefined minimum support level, that new set was considered a relevant cluster. The algorithm’s first intersections were carried out at a three term level, allowing overlap of clusters at this level. Documents that were clustered were removed from further consideration and the process repeated at the two …

Ayatollah Khomeini And The Islamic Revolution In Iran, Dustin John Byrd

Masters Theses

This thesis examines the events leading up to the 1979 Islamic Revolution in Iran and the role of Ayatollah Ruhollah Khomeini in bringing about that revolution. It attempts to demonstrate the social, psychological, political, and religious factors that led to the rise of Khomeini as the leader of the revolution. It furthermore focuses on Khomeini's strategy to oppose, destabilize, and eventually overthrow the Shah of Iran through various means. This thesis is limited to the study of Khomeini as a revolutionary figure, not as a head of state, and therefore I do not examine Khomeini after the overthrow of the …

The Protective Order Process As A Victim Empowering Response To Domestic Violence: An Investigation In A Rural Iowa Setting, Traci L. Ketter

Masters Theses

This research began its evolution as i began with an interest in societal responses to domestic violence. I was curious about protective orders, as they seem to be relied upon heavily by our legal system. As one of the primary responses to domestic violence, I wanted to know whether this type of response was meeting the needs of petitioners. As I read the literature and formed research questions, it became clear that in order to answer the questions I had, I would need to go to the victims themselves. They would be the best source of information on the role …

Identification And Characterization Of Cellular Targets Of The Bacterial Cytotoxin Yopt In Saccharomyces Cerevisiae, Paul David Caccamo

Masters Theses

Human pathogenic Yersinia spp. utilize Type III Secretion to deliver six effector proteins into host cells. The injected proteins resemble eukaryotic signal transduction molecules and are capable of disrupting signaling pathways in order to subvert the functions of the targeted cell or disrupt communication with surrounding cells. As a result, bacterial invaders are not only able to survive the threat of a host immune response, but can thrive despite it. YopT is a cysteine protease that cleaves RhoGTPases, releasing them from the membrane and thus from their role as initiators of signaling pathways, including the nucleation of actin and …

Selection Of Attractor Sounds For An Audio-Based Navigation System For The Visually Impaired, Brad Salisbury

Masters Theses

Research in to human hearing has been very ‘laboratory’ oriented in the sense that the test environments do not replicate most ‘real world’ situations [J.C. Middlebrooks and D.M. Green, Ann. Rev. of Psychology, 42, 135-159 (1991)]. While very useful information is gained from these types of tests, it is difficult to see how ‘real world’ situations affect sound source localization, recognition, and navigation (walking/way finding) performance. Such information is especially important to people who are visually impaired and dependent on prior knowledge of the environment or audio cues for travel. The research reported here was conducted during the development of …

Masters Theses

This project investigates aspects of diet, health, and lifestyles of enslaved Africans of Bridgetown, Barbados during the 17th-19th centuries. The dentition of 10 Pierhead and Fontabelle individuals was examined to provide evidence of stress and coping capacities experienced within the urban context of slavery. Linear enamel hypoplasias (LEH), dental disease, and cultural modifications were noted. The frequencies of the pathologies were calculated and the peak age of stress occurrence for LEH were timed and compared with other New World enslaved populations in order to determine if differences existed in overall health and lifestyle experiences between those enslaved in cities and …

Vertebral Age Estimation: An Examination Of The Seventh Cervical, Seventh Thoracic, And Fourth Lumbar Vertebrae, Holly Hernandez

Masters Theses

This project examines the utility of vertebral osteophyte development to estimate age at death. Skeletal joint degeneration is a common method for estimating individuals' age at death, however studies regarding vertebral degeneration and age estimation are lacking. My study follows the work of Stewart (1958) in comparing stages of osteophytic lipping of vertebral bodies to age at death.

I examined the seventh cervical (C7), seventh thoracic (T7), and fourth lumbar (L4) vertebrae in 100 individuals of known ancestry, sex, and age at death from the Hamann-Todd skeletal collection. Degenerative stages and composite scores were analyzed through descriptive statistics and chi …

Changes In Microbial Community Structure Of Petroleum Contaminated Sediments Are Reflected In Subsurface Geophysical Signatures, Jonathan P. Allen

Masters Theses

Petroleum contamination of sediments leads to dynamic changes in the subsurface. These include changes in the microbiota as well as in the subsurface geophysical and geochemical properties. Anomalously high conductivity values observed in subsurface zones contaminated with light non aqueous phase liquids (LNAPLs) have been suggested to be the result of microbial activity. Therefore, we investigated the interdependence between geoelectrical signatures and microbial community structure in petroleum contaminated field sediments and laboratory column experiments. Spatial and temporal changes in electrical conductivity of the subsurface paralleled changes in microbial community composition, with the highest conductivity values concomitant with specific anaerobic hydrocarbon-degrading …

Neoliberalism, Hegemony And Community Imaginings, Boone W. Shear

Masters Theses

The idea of "community" evokes many long held, positive imaginings. Community implies neighborliness, togetherness, helping each other, tolerance and understanding. Community is set against modem society and is commonly understood to be a solution to the deleterious impacts of capitalism and the state. Although community can be a site of resistance, I am also interested in the ways in which the ideology of community assists in facilitating capitalist inequalities.

The latter part of the twentieth-century saw a significant restructuring of capital in the United States as privatization and deregulation were accompanied by a decline in the welfare state. These efforts …

Democracy, Hegemony, And Consent: A Critical Ideological Analysis Of Mass Mediated Language, Michael Alan Glassco

Masters Theses

Accepting and incorporating mediated political discourse into our everyday lives without conscious attention to the language used perpetuates the underlying ideological assumptions of power guiding such discourse. The consequences of such overreaching power are manifest in the public sphere as a hegemonic system in which free market capitalism is portrayed as democratic and necessary to serve the needs of the public. This thesis focuses specifically on two versions of the Society of Professional Journalist Codes of Ethics 1987 and 1996, thought to influence the output of news organizations. This analysis exposes the problems inherent in the news media's focus of …

Examining The Structural Covariates Of Methamphetamine Use: A Social Disorganization Perspective, Justin Smith

Masters Theses

There have been many anecdotal accounts describing the characteristics of individuals involved in methamphetamine use, trafficking and production. However, prior to the current study there was yet to be a macro-level analysis of methamphetamine use. The extant macro-level literature on drug use has suggested that areas with high levels of social disorganization experience high rates of drug use. It was expected that school-districts with low SES and high rates of ethnic heterogeneity, residential instability and family disruption will experience high rates of methamphetamine use. In addition, it was expected that rural school districts would show higher rates than urban and …

Characterization Of Fracture Systems In Sublette County, Wyoming Using P-Wave And C-Wave 3d Seismic, Keith R. Johnson

Masters Theses

Birefringence of seismic shear waves has proven to be a useful tool for identifying fracture intensity and orientation in the subsurface. Naturally occurring fractures have been shown to contribute to the deliverability of natural gas production in some reservoir formations in Rocky Mountain sedimentary basins. A multicomponent 3D 3C seismic survey acquired on the southeastern end of Pinedale Anticline in Sublette County, Wyoming was mapped to characterize fault systems within the sedimentary section. The tectonic and depositional history in the study area was determined by literature search and by one-dimensional backstripping. Compressional and wrench fault systems were observed and mapped. …

The city of Segovia, Spain is known for its Acueducto (Aqueduct), the Alcazar Castle, its Catedral (Cathedral), la Casa de la Moneda de Segovia (the House of Money of Segovia), and over 60 additional historical buildings, monuments, and protected vistas. This abundance qualified the city for designation in 1986 as a World Heritage site under guidelines established by the United Nations Education and Scientific and Cultural Organization (UNESCO). World Heritage Site status is coveted by city and regions around the world, but little research conducted in Spain has been recorded in English to determine if receiving this status actually affects …

Occupational Stress And Slavery: Evidence From Bridgetown, Barbados, Sarah Muno

Masters Theses

In 1996 and 2000, construction workers uncovered unmarked burial grounds in the Pierhead and Fontabelle sections of Bridgetown, Barbados. The human remains were removed in salvage excavation and are now housed at the University of the West Indies and the Barbados Museum and Historical Society. The associated grave goods, documentary record, and initial osteological analysis indicate these individuals were part of the enslaved workforce during the early to mid- eighteenth century. This thesis will explore the presence of vertebral osteophytosis, vertebral anterior wedge compression fractures, vertebral apophyseal facet remodeling and musculoskeletal stress markers among the human remains from Pierhead and …

Coordination Environment: A New Approach To The Sensing Of Lead (Ii) Itself, Kristina Marie Nespechal

Masters Theses

Lead(II) is a silent poison that has plagued society since 3800 B. C. The average intake of lead in the United States alone is 50 μg per day, which is approximately 100-1000 times greater than that of prehistoric lead levels. Regardless of the banning of lead in paints and gasoline, lead poisoning prevails as a major environmental health risk. Science has the ability to address the concern with this environmental contaminant. The future production of an economical and reliable test kit for lead(II) relies on the luminescence of the heavy metal itself.
