A Meta-Analysis And Risk Assessment Of Heavy Metal Uptake In Common Garden Vegetables., Trent David Lecoultre

Electronic Theses and Dissertations

Peer reviewed literature was searched to identify research pertaining to the uptake of heavy metals (As, Cd, Pb and Zn) by vegetables (cabbage, carrot, lettuce, and radish). The objectives of this research were to 1) determine the relationship between heavy metal concentrations in the soil and heavy metal concentrations in vegetables, and 2) determine the level of risk associated with exposure to heavy metals through ingestion of contaminated vegetables. Highly variable estimates and biologically implausible regression equations resulted from this meta-analysis. Exposure to arsenic through the ingestion of lettuce grown on contaminated soil significantly increases cancer risk, especially in children. …

Iron Acquisition In Rhodococcus Erythrolpolis: The Isolation Of Mutant(S) That Do Not Produce A Siderophore., Jaishree M. Vellore

Electronic Theses and Dissertations

Rhodococcus, a soil bacterium, displays a diverse range of metabolic capabilities with a number of potential practical applications. To exploit the metabolic potential of Rhodococcus, their basic physiology, genetics, and especially the acquisition of essential nutrients like iron, must be understood.

R. erythropolis strain IGTS8 releases a small compound called a siderophore, that scavenges ferric iron from the environment. To learn more about the genetic control of iron acquisition, mutant(s) defective in siderophore production were isolated. Mutants were generated, by inserting a mutagenic plasmid, pJCS506, into the bacterial cell using electroporation. The plasmid, which cannot replicate in these …

Molecular Studies Involving The Rev Protein Of Caprine Arthritis Encephalitis Virus And Visna Virus., Bridget Michele Graves

Electronic Theses and Dissertations

Caprine Arthirtis Encephalitis Virus (CAEV) and Visna Virus are two viruses of the lentivirus family. They encode three structural genes (gag, pol, and env) and two regulatory genes (rev and tat). The Rev protein regulates Gag, Pol and Env expression by transporting their mRNAs to the cytoplasm by binding to the RRE (Rev Response Element) found on their mRNAs. Previous studies have indicated that Rev may be toxic to transfected cells, overexpression of exogenous RREs or a better binding RRE can inhibit Rev activity and Rev-C (CAEV Rev) can trans-activate RRE-V (Visna Virus …

The Impact Of Logging On Aquatic Salamander Communities., Heather Noel Mcdonald

Electronic Theses and Dissertations

For this study, the abundance of the salamander fauna in two streams was compared to determine the impact of logging activities. After five months of study, the area around one stream was logged by the National Forest Service. Following logging, the abundance of salamanders in the stream was greatly reduced, while the population in the undisturbed stream remained relatively unchanged. Six abundant species were used as indicators; two of these species (Desmognathus quadramaculatus and Desmognathus ochrophaeus) were negatively affected by the logging, while four species (Demognathus fuscus, Desmognathus monticola, Eurycea wilderae, and Gyrinophilus porphyriticus …

Remembering The Forgotten Genocide: Armenia In The First World War., Dana Renee Smythe

Electronic Theses and Dissertations

The Ottoman Empire was in serious decline by the late nineteenth century. Years of misrule, war, and oppression of its various nationalities had virtually driven the Turks from Europe, leaving the weakened Empire on the verge of collapse. By the 1870s the Armenians were the most troubling group, having gained international sympathy at the Congress of Berlin. As a result, violence against the Armenians had escalated dramatically by the turn of the century. They felt, however, that their fortune had changed when the liberal Young Turks seized power from the Sultan in 1908. Unfortunately, the Young Turks had a much …

Historical Linguistic Analysis Of Traditional English Christmas Carols., Tami Lynn Baker

Electronic Theses and Dissertations

Through the process of historical linguistics it is possible to determine approximate dates of authorship and meaning that establish the conventions of a particular genre. To accomplish such a study, elements of phonology, morphology, and syntax are compared and the results create a field of descriptors representative of a style of writing of a period.

By using the method on eight well-known Christmas carols, four were determined to have been written prior to the dates previously speculated, possibly originating in the Middle Ages. The remaining four were written based on the conventions set by the earlier medieval carols.

The "Jaded Traveller": John Jasper's Failed Psychic Quest In Charles Dickens's The Mystery Of Edwin Drood., Linda Poland Pridgen

Electronic Theses and Dissertations

This thesis is a Jungian study of John Jasper, the central character in Charles Dickens's The Mystery of Edwin Drood. Jasper fails to achieve psychological wholeness because he suffers from what Carl G. Jung calls dissociation of consciousness, a malady that prevents Jasper from entering the process of individuation--a process of self-discovery. Jasper's boredom, self-alienation, hypocrisy, and secret double life impede his search for self.

Faced with projections of his anima and shadow self, Jasper has many opportunities for psychological and spiritual growth. But rather than integrate the aspects of his personality that each of the anima and shadow …

A Comparative Analysis Of Upton Sinclair's The Jungle And Emile Zola's Germinal., Mouhamedoul Amine Niang

Isaac Bashevis Singer: Speak English, Think Yiddish-- Adaptation Versus Assimilation., Susan L. Gardberg

Electronic Theses and Dissertations

Critics use the words "vanished culture" to describe Isaac Bashevis Singer's work for Polish Jewry had been destroyed. However, Singer's characters survive the travails of anti-Semitism and resettle in America. This study explores Singer's Polish Jews to determine whether they assimilate into their new culture; or maintain their strong Jewish traditions and adapt to the freedoms of America.

Singer's life is analyzed, including the people and places that have influenced his work. Two of Singer's works are examined in this thesis. Chapters Three and Four explicate an allegorical short story, "The Little Shoemakers." Singer writes a fairytale view of a …

Women At The Loom: Handweaving In Washington County, Tennessee, 1840-1860., Ann Cameron Macrae

Electronic Theses and Dissertations

This thesis explores the evidence for handweaving in antebellum Washington County, Tennessee. The author examines probate inventories, wills, store ledgers, and census and tax materials to determine the identities of the weavers, the equipment and raw materials available to them, and the kinds of textiles that women wove. The author discusses the reasons many women continued to weave cloth at home although commercially woven textiles were available in local stores.

The author concludes that many of Washington County's antebellum weavers wove as a contribution to the country goods the family bartered at the local store. Others may have been responding …

Local And Systemic Controls On Fish And Fish Habitat In South Dakota Rivers And Streams: Implications For Management, Craig L. Milewski

Electronic Theses and Dissertations

Assessments of the health of rivers and streams in prairie environments would improve if the role of systemic patterns and processes among geologic-climatic settings in controlling physical habitat and fish communities were better defined. My research approach was based on a premise that assessments of the health of rivers and streams in prairie environments would benefit from studies that 1) examine the moderating effects of systemic patterns and processes by comparing physical habitat continua and fish communities among geologic-climatic settings, 2) determine the relative influence of locally interacting variables (e .g., channel shape and riparian vegetation) and systemic processes in …

The Status And Distribution Of The Topeka Shiner Notropis Topeka In Eastern South Dakota, Carmen M. Blausey

Electronic Theses and Dissertations

The Topeka shiner Notropis topeka is a small (< 75 mm) minnow that inhabits prairie streams in several north central plains states. Once widespread and abundant throughout its historic range, the Topeka shiner is now found only in isolated populations. Because of an 80% reduction in occurrence throughout their range, the U.S. Fish and Wildlife Service listed the Topeka shiner as endangered in January 1999. At the time, limited information on habitat preferences and dist1ibution existed for this species in South Dakota. The objectives of this study were to measure local habitat features and water quality conditions at the reach scale at Topeka shiner study sites, create a model using these data to determine favorable habitat conditions, and identify fish species commonly associated with Topeka shiners. Fish and habitat data were collected at 61 tributary sites of the James, Vermillion, and Big Sioux rivers from June through September in 1999 and 2000. Sample sites in 1999 were based on historic Topeka shiner records in the South Dakota Natural Heritage Database. Sample sites in 2000 were based on a draft GIS model identifying potential Topeka shiner streams. Fish were collected with seines between block nets and standard procedures were used to measure physical and hydrological features of stream reaches. Cyprinids dominated the fish community for each river basin during both sample years. Insectivores and omnivores were the dominant trophic classes for each river basin for both sample years. Fish community associations for Topeka shiners were based on two stepwise logistic regression models: abundance of individual species at each site and presence or absence of individual species at each site. The abundance model indicated that Topeka shiners were most commonly associated with orangespotted sunfish Lepomis lutrenis and tadpole madtoms Noturns gyrinus. The presence/absence model showed that Topeka shiners were typically associated with red shiners Notropis lutrenis, tadpole madtoms Noturns gyrinus, black bullheads Ameiurus melas, and bigmouth shiners Notropis dorsalis. Habitat preferences were based on three stepwise logistic regression models: physical habitat water quality, and substrate composition at the reach scale. The physical habitat model indicated that Topeka shiners are associated with stream reaches that had low animal use, overhanging vegetation, stream bank vegetation comprised of sedges/rushes, low depositional zones, and run macrohabitat. The water quality model did not indicate any favorable or preferred conditions. The substrate model indicated that Topeka shiners are associated with stream reaches that had fine gravel or cobble substrates. The results of my study will lead to a better understanding of Topeka shiner distribution and habitat, and aid federal and state agencies in making management decisions that provide for protection and preservation of this species.
