Parameterized Spectral Bathymetric Roughness Using The Nonequispaced Fast Fourier Transform, David H. Fabre

LSU New Orleans Theses and Dissertations

The ocean and acoustic modeling community has specifically asked for roughness from bathymetry. An effort has been undertaken to provide what can be thought of as the high frequency content of bathymetry. By contrast, the low frequency content of bathymetry is the set of contours. The two-dimensional amplitude spectrum calculated with the nonequispaced fast Fourier transform (Kunis, 2006) is exploited as the statistic to provide several parameters of roughness following the method of Fox (1996). When an area is uniformly rough, it is termed isotropically rough. When an area exhibits lineation effects (like in a trough or a ridge line …

Petroleum Play Study Of The Keathley Canyon, Gulf Of Mexico, Jean Pierre Malbrough

LSU New Orleans Theses and Dissertations

Beneath Keathley Canyon (KC) off the Southern Coast of Louisiana and Texas, allochthonous salt bodies have attained thicknesses of over 7620 m (25000 feet), providing excellent seals and migration pathways for hydrocarbons produced by post-rift sedimentary deposition. This study analyzes a small portion of the KC area, utilizing Petrel Seismic software and well information from the KC102 (Tiber) well.

An intra-Miocene wedge, expressed beneath salt, may provide information about movement of allochthonous salt over Wilcox sands, sediment compaction, and hydrocarbon pathways. Progradational sedimentation is the driving force which leads to faulting in the early Miocene, allowing Jurassic salt to rise, …

The Role Of Genetic Alterations In Tumor Initiation, Progression And Transformation, Weiwei Zhang

Theses & Dissertations

Follicular lymphoma (FL) is the second most common lymphoma in the United States. Although it is generally an indolent lymphoma, FL is not curable, and, in about 30% of patients, the FL undergoes transformation into an aggressive lymphoma (tFL) with marked worsening of prognosis. To identify mutations preferentially present in tFL, we performed whole exome sequencing (WES) on paired FL and tFL arising in the same patients and developed a mutational analysis pipeline. After we identified potentially important genes that have been found to be mutated in our paired FL and tFL study, we constructed a custom capture platform including …

Postural Responses To Perturbations Of The Vestibular System During Walking In Healthy Young And Older Adults, Jung Hung Chien

Theses & Dissertations

It has been shown that approximate one-third of US adults aged 40 years and older (69 million US citizens) have some type of vestibular problems. These declining abilities of the vestibular system affect quality of life. Difficulties in performing daily activities (dressing, bathing, getting in and out of the bed and etc.) have been highly correlated to loss of balance due to vestibular disorders. The exact number of people affected by vestibular disorders is still difficult to quantify. This might be because symptoms are difficult to describe and differences exist in the qualifying criteria within and across studies. Thus, it …

Developing And Testing An Anguilliform Robot Swimming With Theoretically High Hydrodynamic Efficiency, John B. Potts Iii

LSU New Orleans Theses and Dissertations

An anguilliform swimming robot replicating an idealized motion is a complex marine vehicle necessitating both a theoretical and experimental analysis to completely understand its propulsion characteristics. The ideal anguilliform motion within is theorized to produce ``wakeless'' swimming (Vorus, 2011), a reactive swimming technique that produces thrust by accelerations of the added mass in the vicinity of the body. The net circulation for the unsteady motion is theorized to be eliminated.

The robot was designed to replicate the desired, theoretical motion by applying control theory methods. Independent joint control was used due to hardware limitations. The fluid velocity vectors in the …

Response Of Fishes To Restoration Projects In Bayou St. John Located Within The City Of New Orleans, Louisiana, Including Hydrological Characterization And Hydrodynamic Modelling, Patrick W. Smith

LSU New Orleans Theses and Dissertations

Quantifying the impacts of restoration on coastal waterways is crucial to understanding their effectiveness. Here, I look at the impacts of multiple restoration projects on urban waterways within the city limits of New Orleans, LA, with an emphasis on the response of fishes. First I report the effects of two projects designed to improve exchange down estuary on the hydrologic characteristics of Bayou St. John (BSJ). Within BSJ, flow is dominated by subtidal wind driven processes. Removal of an outdated flood control structure did not appear to alter exchange in BSJ, but removal combined with sector gate openings did. I …

Correction Of Verication Bias Using Log-Linear Models For A Single Binaryscale Diagnostic Tests, Haresh Rochani, Hani M. Samawi, Robert L. Vogel, Jingjing Yin

Biostatistics: Faculty Publications

In diagnostic medicine, the test that determines the true disease status without an error is referred to as the gold standard. Even when a gold standard exists, it is extremely difficult to verify each patient due to the issues of costeffectiveness and invasive nature of the procedures. In practice some of the patients with test results are not selected for verification of the disease status which results in verification bias for diagnostic tests. The ability of the diagnostic test to correctly identify the patients with and without the disease can be evaluated by measures such as sensitivity, specificity and predictive …

The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …

Urban Stormwater Management: Treatment Of Heavy Metals And Polycyclic Aromatic Hydrocarbons With Bioretention And Permeable Pavement Technologies, Viktoriya Sirova

Master's Projects and Capstones

Urban stormwater runoff is a major non-point source of pollutants release into the environment. Pollutants of concern include sediments; heavy metals; polycyclic aromatic hydrocarbons (PAHs); petroleum hydrocarbons; and chlorinated organic compounds, such as pesticides and polychlorinated biphenyls. Conventional stormwater management practices are designed to dispose of the runoff as quickly as possible, not to treat the pollutants. Low Impact Development (LID) concept is an alternative approach to the conventional framework that attempts to recreate hydrologically functional landscape mimicking pre-development regimes. This research paper assesses the effectiveness of two LID technologies, bioretention and permeable pavements in treating PAHs and common urban …

Adapting To Rising Sea Levels In San Francisco Bay: The Potential For Thin Layer Sediment Application To Enhance Tidal Marsh Resiliency Through This Century, Scott K. Hine

Master's Projects and Capstones

The research here focuses on two projected century sea-level rise scenarios (100 and 180 cm/century) and the potential to offset elevation loss to sea-level rise by supplying deteriorating tidal marsh habitat with a thin layer of dredge sediment via high-pressure spray disposal within San Francisco Bay. This adaptation strategy is then analyzed for potential integration into the Bay’s long term management plan for dredge material disposal. The Marsh Equilibrium Model (Morris, 2012) is used to evaluate elevation deficits for existing tidal marsh habitat around San Pablo Bay against future century sea-level rise scenarios and model marsh resiliency following elevation enhancement. …

Bodipy-Based Fluorescent Probes For Sensing Protein Surface-Hydrophobicity, Nethaniah Dorh, Shilei Zhu, Kamal B. Dhungana, Ranjit Pati, Fen-Tair Luo, Haiying Liu, Ashutosh Tiwari

Department of Chemistry Publications

Mapping surface hydrophobic interactions in proteins is key to understanding molecular recognition, biological functions, and is central to many protein misfolding diseases. Herein, we report synthesis and application of new BODIPY-based hydrophobic sensors (HPsensors) that are stable and highly fluorescent for pH values ranging from 7.0 to 9.0. Surface hydrophobic measurements of proteins (BSA, apomyoglobin, and myoglobin) by these HPsensors display much stronger signal compared to 8-anilino-1-naphthalene sulfonic acid (ANS), a commonly used hydrophobic probe; HPsensors show a 10- to 60-fold increase in signal strength for the BSA protein with affinity in the nanomolar range. This suggests that these HPsensors …

Two Essays In Finance And Economics: “Investment Opportunities In Commodity And Stock Markets For G7 Countries” And “Global And Local Factors Affecting Sovereign Yield Spreads”, Selma Izadi

LSU New Orleans Theses and Dissertations

In chapter 1, I investigate the return links and dynamic conditional correlations between the equity and commodity returns for G7 countries from 2000:01 to 2014:10. The commodity futures include BCOM Index which contains the futures and spot price of 22 commodities, Brent and Crude oil futures, gold and silver futures, Wheat, Corn and Soybean futures and CRB index. The finding indicates that during the full sample period GOLD, WHEAT and CORN have the smallest dynamic conditional correlations with all the Equity indexes. In addition, the correlations between the GOLD/Equity pairs are negative during the financial crisis. This fact indicates the …

Restoring The Mississippi River Delta In Louisiana Ecological Tradeoffs And Barriers To Action, Alison Maulhardt

LSU New Orleans Theses and Dissertations

This study investigates the Louisiana 2012 Coastal Master Plan’s ability to reconcile conflicting economic and ecological demands on coastal resources. The Louisiana Coastal Master Plan was unique in combining flood control and coastal restoration under one authority. However, the objectives of flood control and coastal restoration can be in conflict. The plan was also unique in its approach of restoration from a working coast perspective. However, the objectives of ecological restoration and economic productivity do not always agree. By conducting semi-structured interviews with major coastal stakeholders, this research will explore how the planning process has accommodated the views and values …

This research project intended to explore the possible relationship between physical activity and academic achievement in college students. Using an anonymous online survey, data was collected over two semesters. Ten thousand currently-enrolled college students ages eighteen and older from all states and recognized territories of the United States participated. The survey gathered data concerning a student’s age, gender, race, body weight, height, geographic region of college attendance, cumulative GPA, and physical activity level. The FIT Index of Kasari was used to classify each student’s physical activity level. A quintile split by FIT score was conducted to determine if physically active …

Antiviral Peptide Nanocomplexes As Potential Therapeutics For The Treatment Of Infectious Diseases, Jinjin Zhang

Theses & Dissertations

Hepatitis C Virus (HCV) is recognized as a major burden in global public health, which can be further exacerbated by several cofactors such as human immunodeficiency virus (HIV). Currently, there is no vaccine for HCV. The emergence of potent and highly specific direct-acting antivirals (DAA) has marked a new era in HCV therapy, however, the remaining issues like affordability, genotype dependency, and potential resistance still necessitate the development of additional therapeutic approaches to be used instead or in combination with DAA.

Recently, the antiviral peptide C5A (in our studies designated as p1) and its cationic derivative p41 have been identified …

Utilizing Ecological Connectivity In California Desert Wilderness Preservation, Lauren Kahal

Master's Projects and Capstones

The Wilderness Act of 1964 gave the federal land management agencies—the National Park Service, United States Forest Service, U.S Fish and Wildlife Service, and Bureau of Land Management—the authority to identify, propose, and manage lands as wilderness. Wilderness, once approved by Congress for inclusion in the National Wilderness Preservation System, is offered the highest form of land preservation in the nation. However, the wilderness identification process used by the implementing agencies is based on a half-century old statute with an aging definition of wilderness. While designated wilderness can protect the plant and wildlife communities within its borders from direct anthropogenic …

The Effects Of An Overnight Environmental Science Education Program On Students' Attendance Rate Change For Middle School Years, Jennifer Elizabeth Basham

Dissertations and Theses

Programs that engage middle students in participatory, real-world, and hands-on field based instruction can be a powerful asset to the educational experiences for students; motivating and inspiring some to appreciate and value school in a different way. Overnight environmental science programs have a unique opportunity to support students by creating experiences where students can participate in learning in vastly different ways from what they may engage with in the traditional 4-walled classroom, while concurrently developing a relationship with the natural world. Decreasing educational budgets and increased need to substantiate educational programs in terms of their impact on students has added …

Stabilized Least Squares Migration, Graham Ganssle

LSU New Orleans Theses and Dissertations

Before raw seismic data records are interpretable by geologists, geophysicists must process these data using a technique called migration. Migration spatially repositions the acoustic energy in a seismic record to its correct location in the subsurface. Traditional migration techniques used a transpose approximation to a true acoustic propagation operator. Conventional least squares migration uses a true inverse operator, but is limited in functionality by the large size of modern seismic datasets. This research uses a new technique, called stabilized least squares migration, to correctly migrate seismic data records using a true inverse operator. Contrary to conventional least squares migration, this …

From Boolean Equalities To Constraints, Sergio Antoy, Michael Hanus

Computer Science Faculty Publications and Presentations

Although functional as well as logic languages use equality to discriminate between logically different cases, the operational meaning of equality is different in such languages. Functional languages reduce equational expressions to their Boolean values, True or False, logic languages use unification to check the validity only and fail otherwise. Consequently, the language Curry, which amalgamates functional and logic programming features, offers two kinds of equational expressions so that the programmer has to distinguish between these uses. We show that this distinction can be avoided by providing an analysis and transformation method that automatically selects the appropriate operation. Without this distinction …

Linear Trend Detection In Serially Dependent Hydrometeorological Data Based On A Variance Correction Spearman Rho Method, Wenpeng Weng, Yuanfang Chen, Stefan Becker, Bo Liu

Publications and Research

Hydrometeorological data are commonly serially dependent and thereby deviate from the assumption of independence that underlies the Spearman rho trend test. The presence of autocorrelation will influence the significance of observed trends. Specifically, the positive autocorrelation inflates Type І errors, while it deflates the power of trend detection in some cases. To address this issue, we derive a theoretical formula and recommend an appropriate empirical formula to calculate the rho variance of dependent series. The proposed procedure of the variance correction for the Spearman rho method is capable of mitigating the effect of autocorrelation on both, Type І error and …

Maternal Predictors Of School Readiness Among At-Risk Head Start Preschool Children, Rachel Chase

Master's Theses and Doctoral Dissertations

Preschool has been identified as a critical period during which children who are at-risk for school difficulties are most responsive to intervention (National Institute of Mental Health, 2002; National Research Council & Institute of Medicine, 2001). Because of this, school readiness has recently become a prioritized area of interest for the educational system, the health care industry, and the federal government. However, many efforts to comprehensively prepare a child to begin school have not been successful because factors beyond the educational system (e.g., parenting/parent attributes, environmental stressors, and other demographic characteristics) have not been closely considered nor adequately researched. Therefore, …

Structural Study Of Pb(Ii) And Sb(V) Adsorption On The Hydroxylated Hematite(1102) Surface, Canrong Qiu, N/A 丘灿荣

Chemistry and Biochemistry

Surface complexation reactions at mineral-water interface play a key role in dictating the mobility and bioavailability of aqueous species in the environment, considering the minerals (like iron-(oxyhydr)oxides), ubiquitous in nature, are usually of high specific surface area and contain a lot of potentially reactive surface sites for binding ions. Thus, the fundamental understanding of surface complexation reactions is essential to better model the environmental fate and transport of toxic aqueous species. In the current study, the hematite (1102) surface was selected as a model substrate for iron-(oxyhydr)oxides commonly found in the environment to investigate the surface complexation reactions of Pb(II) …
