Hydrology Of The Springs, Seeps, And Fens At The Nature Conservancy's Pigeon Point Preserve, Ransom County, North Dakota, Corey W. Askin

Theses and Dissertations

Pigeon Point lies along the Sheyenne River in the west-central part of the Sheyenne Delta Aquifer, southeastern North Dakota. Groundwater discharges along a north-facing bluff at Pigeon Point and forms springs, seeps, and fens 'hosting atypical boreal species. The Nature Conservancy owns 231 ha at Pigeon Point, a tract that also includes the largest and least disturbed spring-fed stream in the region as well as some of the finest riparian forest in the state. In response to possible future groundwater diversion, the objectives of this study are: 1) to characterize the Sheyenne Delta Aquifer up-gradient from Pigeon Point, 2) to …

Reevaluation Of Species Concepts Of Uppermost Cretaceous Unionidae (Mollusca: Bivalvia) : Hell Creek Formation, Montana, U.S.A., Marron J. Bingle

Theses and Dissertations

Species are the basic units of life relative to taxonomy, and a practical definition of species is imperative to paleontology in order to promote reproducible, unambiguous criteria for accurately interpreting past species relationships. The need for a well-defined rubric for identifying species is evident in the freshwater mussel assemblage (Family Unionidae) in the Hell Creek Formation. The Hell Creek Formation unionid species were first described by Whitfield in 1903 and 1907. His descriptions were often based on differences of a single trait. In 1976, Russell reevaluated the original species descriptions, I but still based the classification of species on only …

Isotopic Tracers As Evidence Of Denitrification In The Karlsruhe Aquifer, Eben J. Spencer

Theses and Dissertations

The Karlsruhe Aquifer of north-central North Dakota has experienced considerable nitrate contamination sparking an investigation by the North Dakota State Water Commission. Certain portions of the aquifer have experienced nitrate-N concentrations of up to seven times the drinking water standard. Although contamination is evident it is possible the NO₃¯ is naturally being eliminated by denitrification, whereby bacteria reduce NO₃¯ to nitrogen gas. Evidence of denitrification may be illustrated by accelerated reduction of NO₃¯ relative to the conservative tracer Cl¯ coupled with an increase in the heavy isotopes of 15N and 18O within the NO₃¯ ion. Such an increase is not …

Regional Stratigraphy Of The Newcastle Formation (Lower Cretaceous) In Eastern Montana And Western North Dakota, Adam J. Ulishney

Theses and Dissertations

The Newcastle Formation (Lower Cretaceous) consists of sandstone with interbedded shale, siltstone, and mudstone facies. This work shows that the regional stratigraphy of the unit is detailed enough for the interpretation of its depositional history and environments in eastern Montana. This work also illustrates the possible lowstand position of the Western Interior Seaway along with probable source areas providing sediments into the study area.

A total of 3446 geophysical wireline logs were used to determine formation tops of the Greenhorn, Mowry, Newcastle, Skull Creek, and Inyan Kara Formations. The log character of the Newcastle Formation was also described for all …

Assessing Recharge And Discharge Across The Prairie Pothole Landscape: Application Of Spatial Hydrological Data And Statistical Analysis In A Groundwater Flow Model, Christopher D. Laveau

Theses and Dissertations

Quantifying the spatial and temporal dynamics between groundwater recharge, discharge, and wetlands is a necessary step to develop effective water management strategies. Wetlands in the northern Great Plains play a role in flood control, water supply, and regional ecology. The water budget of a wetland in the northern prairies is often an unequal balance between moisture input and output in which the permanence of a wetland depends on its groundwater budget. Identifying and quantifying groundwater recharge and discharge zones has applications in predicting the spatial and temporal distribution of wetlands.

The current work involved the application of a groundwater model …

Geomechanics Applied To Reservoir Development In The Coso Geothermal Field, Andrew J. Nygren

Theses and Dissertations

The Coso geothermal field is located approximately 220 kilometers north of Los Angeles, CA. In 2002, a project began to develop the east flank of the Coso geothermal field into an enhanced geothermal system (EGS); in such a system water is injected via injection well(s) into hot dry basement rock through naturally occurring or stimulated fractures. The injected water gathers heat from the reservoir rock before being extracted for direct use or energy production. To develop such a reservoir, adequate understanding of the reservoir geomechanics is necessary. This thesis investigates the state of stress and rock fractures, the existing permeable …

Fabrication Of Core-Shell Nanoparticles, Zhanhu Guo

LSU Doctoral Dissertations

Metallic Cu and Au shells were fabricated around cobalt nanoparticles. A new technique to coat nanoparticles with carbon coatings and poly(methyl methacrylate) (PMMA) was developed. The copper shell formation is a self-limiting process. A thin copper shell (0.82 nm) around the cobalt nanoparticle (1.56 nm) enhanced the magnetic property by increasing the blocking temperature from 124 K to 235 K for nanoparticles with a copper shell. The formed gold shell (0.67 nm) enhanced the cobalt nanoparticle magnetic property by increasing the blocking temperature above room temperature. The magnetic moment in the Co-Cu and Co-Au core-shell nanoparticle is much higher than …

The Role Of Teachers' Self-Efficacy In Increasing Children's Physical Activity, James Frederick Roth

LSU Doctoral Dissertations

It is well documented that elementary school children do not participate in recommended amounts of physical activity, and that elementary physical education programs generally are unable to insure that children engage in appropriate amounts of activity. One solution to this dilemma is to increase children’s activity levels through collaborative efforts such as whole school programs involving the classroom teachers. If this approach is to be successful, it is important to investigate ways that elementary classroom teachers can be actively involved in school level programs that will ultimately increase children’s physical activity levels. Elementary classroom teachers are often responsible for at …

Effects Of Body Size On Goose Behavior: Lesser Snow Goose And Ross's Goose, Jon Einar Jonsson

LSU Doctoral Dissertations

Body size is highly variable among geese, both at intra- and interspecific levels. Interspecific variation in several behaviors has been attributed to differences in body size in geese: incubation constancy, tendency to maintain family units, and time spent foraging. Body size has important physiological implications for birds, mostly because mass-specific metabolic rate is greater for birds of smaller mass. The Body-size Hypothesis predicts that smaller species deplete their energy reserves at relatively faster rates than do larger species. Hypotheses and conclusions concerning effects of body size on waterfowl behavior often are based on comparisons of species that confront different climates, …

Participants in the study were one hundred, fifty-two (152) SSS students who entered this university in the fall of 1996 and fall of 1997. Tinto’s (1987) longitudinal model of institutional departure was used as the conceptual framework for this study. Services provided by the SSS program …

Photocatalysis In A Novel Semiconducting Optical Fiber Monolithic Reactor For Wastewater Treatment, Hongfei Lin

LSU Doctoral Dissertations

The development of photocatalytic reactors is essential for the successful exploitation of heterogeneous photocatalysis on semiconductor particles, which has been shown to be an effective means of removing organic pollutants from wastewater streams. In this dissertation, a novel photocatalytic optical fiber monolith reactor (OFMR), which employed a ceramic multi-channel monolith as a support for TiO2 and quartz fibers inserted inside the monolithic channels as both a light-transmitting conductor and a support for TiO2, was developed for wastewater treatment by investigating the photocatalytic degradation of o-dichlorobenzene (DCB) and phenanthrene (PHE). This configuration provides a high surface area for catalyst coating per …

Spatial And Temporal Estimation Of Pumping And Recharge In Groundwater System Analysis, Sherly Hartono

LSU Doctoral Dissertations

In many parts of the U.S., groundwater is used as the primary or secondary source of water for the public supply, agricultural, and industrial sectors. In southwestern Louisiana, a majority of the water demand is supplied by the Chicot aquifer. Numerical flow models are useful for managing and optimizing groundwater systems. However, many important model parameters are difficult to quantify, exhibit a certain degree of uncertainty, and may vary both spatially and temporally. Two of the most important and sensitive parameters for a regional groundwater model of the Chicot aquifer are pumping rates and recharge. The use of GIS-based methods …

Jean-Paul Sartre's Les Mots And The Nouvelles Autobiographies Of Alain Robbe-Grillet, Nathalie Sarraute, And Marguerite Duras: A Comparison, Julie Driessen

LSU Doctoral Dissertations

Jean-Paul Sartre's autobiography Les Mots (1964) is shown to be a departure from the Sartrean oeuvre because it represents an abandonment of littérature engagée. In Les Mots Sartre not only abandons littérature engagée, but also embraces a view of literature which he formerly opposed--l'art pour l'art. Sartre defines his views of literature--littérature engagée--in Qu'est-ce que la littérature? (1948) Robbe-Grillet defines l'art pour l'art in Pour un nouveau roman (1963). In Les Mots Sartre embraces Robbe-Grillet's l'art pour l'art and abandons his own littérature engagée. Since these two views of literature are theoretically opposed, it is interesting to find that Sartre …

Civil War Prisons In American Memory, Benjamin Gregory Cloyd

LSU Doctoral Dissertations

The memory of Civil War prisons has always been contested. Since 1861, generations of Americans struggled with the questions raised by the deaths of approximately 56,000 prisoners of war, almost one-tenth of all Civil War fatalities. During the war, throughout Reconstruction, and well into the twentieth century, a sectional debate raged over the responsibility for the prison casualties. Republican politicians invoked the savage cruelty of Confederate prisons as they waved the bloody shirt, while hundreds of former prisoners published narratives that blamed various prison officials and promoted sectional bitterness. The animosity reflected a need to identify individuals responsible for the …

Ceo Succession Processes And Agency Costs, Zeynep Ayca Altintig

LSU Doctoral Dissertations

In the 'passing the baton' succession process, the incumbent CEO/Chairman relinquishes the CEO title, but retains the Chairman title to facilitate monitoring the new CEO during a probationary period. The new CEO eventually wins the Chairman title if he is successful during the probationary period. We argue that this type of succession process can lead to managerial conformism and conservatism because reputation concerns give the retiring CEO incentives to pressure the new CEO to continue existing policies and to avoid making major changes that could substantially improve performance or increase firm value. Consistent with this hypothesis, we find no changes …

Schoolin' Women: Hip Hop Pedagogies Of Black Women Rappers, Nichole Ann Guillory

LSU Doctoral Dissertations

The curriculum studies field has much to gain from an analysis of black women rappers’ texts. The knowledge black women rappers offer through their songs is worthy of study in schooling spaces and is too valuable for educators to continue to ignore if they want to become better teachers. Through their lyrics, black women rappers situate themselves in a public context and construct texts that represent young black women’s complex identities. Black women rappers create a space in hip hop discourse from which their stories enrich and complicate the public conversation about the representation of black women’s identities. This study …

Power, Money, And Sex(Uality): The Black Masculine Paradigm, Kendric Coleman

LSU Doctoral Dissertations

This study develops the Black Masculine Paradigm (BMP), a construct used to trace historically specific components that inform black masculinity and explores the physical and psychological defensive strategies employed by black men in Richard Wright's Black Boy, Claude Brown's Manchild in the Promisedland, Nathan McCall's Make Me Wanna Holler, and James Earl Hardy's B-Boy Blues. Specifically, this project offers that power, money, and sex(uality) are located at the core of the BMP, and these social objectives are negotiated through politicization, prescribed masculinity, and heterosexuality. This project reads the politicization of the black male body through its presence in literature and …

Chemical Vapor Deposition Of Thin Films For Ulsi Interconnect Metallization, Lidong Wang

LSU Doctoral Dissertations

We have studied the kinetics of copper chemical vapor deposition (CVD) for interconnect metallization using solution delivery of Cu(hfac)2 (Cu(II) hexafluoroacetyl-acetonate) dissolved in isopropanol. We observe a growth rate of 17.7 „b 1.5 nm/min at reference conditions of 300„aC substrate temperature, 0.025 Torr Cu(hfac)2 partial pressure, 1.6 Torr isopropanol (reducing agent), and 80 Torr H2 (carrier gas). The film resistivity approaches the bulk value of copper for film thickness greater than 100 nm. Reaction order experiments show first-order kinetics with respect to Cu(hfac)2 partial pressure and zero-order with respect to isopropanol. A series reaction mechanism including three kinetically significant steps …

High Temperature Stress Responses Of Salvia Splendens And Viola X Wittrockiana, Seenivasan Natarajan

LSU Doctoral Dissertations

One of the greatest impediments affecting growth and development of bedding plants is high temperature stress. The deleterious effects of high temperature stress are the most pronounced during plug transplant and/or during the transition period from the nursery to the landscape. High temperature stress responses were investigated in Salvia splendens and Viola x wittrockiana to determine the morphological and physiological mechanism associated with the heat tolerance. Two genotypes for each species were used; a heat tolerant Vista and a heat sensitive Sizzler cultivar of salvia and Crystal Bowl Purple (CBP) a heat tolerant and Majestic Giant Red (MGR) a heat …

Navigating Dangerous Constitutional Straits: A Prolegomenon On The Federal Marriage Amendment And The Disenfranchisement Of Sexual Minorities, Ronald J. Krotoszynski Jr., E. Gary Spitko

Articles

Navigating Dangerous Constitutional Straits A Prolegomenon on the Federal Marriage Amendment and the Disenfranchisement of Sexual Minorities considers the nature of the constitutional amendment process and the Supreme Courts historical approach to incorporating new amendments into the existing constitutional text Professors Krotoszynski and Spitko argue that given the Supreme Courts consistent narrow reading of new amendments to preserve preexisting constitutional rights the Federal Marriage Amendment must be broadly written to override expressly due process and equal protection guarantees against not only sexual orientation discrimination but also gender discrimination In our view however if a proposed Federal Marriage Amendment were sufficiently …
