Mercury Toxicity In Neuronal Cells, Tony Henry

Theses (Pre-2016)

The goal of this study was to employ an in vitro mesencephalic cell model, to better understand the cellular mechanisms and pathways involved in neuronal cell damage, a major component of mercury neurotoxicity. The objectives were to determine the effects of mercury on cell death, the role of oxidative stress in mercury exposure. The mesencephalic cell line was chosen because it has been shown to be more sensitive to a number of neurotoxins and provided a superior and more appropriate model for this study. Cultured cells were treated with mercury salt at concentrations of and incubated for 2 hours. Following …

The Moderating Effects Of Parenting On The Development Of Externalizing Problems In Toddlers, Sarah Robison

LSU New Orleans Theses and Dissertations

Clarifying processes associated with emerging externalizing behavior problems during early childhood was the focus of this study. Data were collected from 100 parent-child dyads when children were 2, 3, and 4 years. An incremental risk model was hypothesized to explain the emergence of externalizing behavior problems. Theoretically, children's temperamental propensity towards negative emotional reactivity increases risk for noncompliance, noncompliance that increases risk for externalizing behaviors by age 4. Parenting was identified as the mechanism by which children's progression along the incremental risk pathway is amplified or minimized; progression is only expected under conditions of harsh parenting. No statistical support emerged …

The Cloning And Characterization Of Two Rop/Rac G-Proteins From Gossypium Hirsutum, Nicole Asprodites

LSU New Orleans Theses and Dissertations

Rop/Rac proteins are plant-specific monomeric guanosine triphosphate-binding proteins (G-proteins) with important functions in plant development. Until recently, only three cotton (Gossypium hirsutum) Rop/Rac G-protein genes were sequenced, representing subfamilies III and IV of the plant monomeric Gprotein family. In this project, members of subfamilies II and I were cloned, sequenced, and named GhRac2 and GhRac3, respectively. Using real-time reverse transcription PCR, expression of GhRac2 was highest during fiber elongation, decreasing significantly when cellulose biosynthesis began. Transcript abundance of GhRac3 doubled between fiber elongation and secondary wall synthesis, remaining constant until 20 days post-anthesis. Expression of GhRac2 and GhRac3 was compared …

A Multi-Dimensional Width-Bounded Geometric Separator And Its Applications To Protein Folding, Sorinel Oprisan

LSU New Orleans Theses and Dissertations

We used a divide-and-conquer algorithm to recursively solve the two-dimensional problem of protein folding of an HP sequence with the maximum number of H-H contacts. We derived both lower and upper bounds for the algorithmic complexity by using the newly introduced concept of multi-directional width-bounded geometric separator. We proved that for a grid graph G with n grid points P, there exists a balanced separator A subseteq P$ such that A has less than or equal to 1.02074 sqrt{n} points, and G-A has two disconnected subgraphs with less than or equal to {2over 3}n nodes on each subgraph. We also …

Nanomaterials Self-Assembly Driven By Beta-Amyloid Peptides, Maria Elena Tanase

LSU New Orleans Theses and Dissertations

Nanomaterials such as gold nanowires and gold nanoparticles were self-assembled with several peptides derived from betaamyloid peptide. The peptides propensity to form fibrilar structures was exploited. The products obtained by aggregation of the peptides with the nano materials were studied using HPLC, UV-vis spectroscopy, TEM and optical light microscopy.

Construction Of Some Unbalanced Designs For The Partition Problem, Yuefeng Wu

LSU New Orleans Theses and Dissertations

In a pioneering work, Bechhofer (1954) introduced the concept of indifference-zone formulation and formulated some methodologies in the case of the problem of selecting the best normal population. In statistical literature, many vector-at-a time and unbalanced methodologies are available for the selecting the best normal population. However, the literature is not that rich for the partition problem. In this thesis, an unbalanced methodology of sampling along the lines of Mukhopadhyay and Solanky (2002) is introduced for the partition problem. A two-stage and a purely sequential procedure are introduced which take c observations from the control population from the control population …

The Kinetics Of Particulate Substrate Utilization By Bacterial Films, Joshua Boltz

LSU New Orleans Theses and Dissertations

There is a need to develop a mathematical expression capable of describing the removal of particulate chemical oxygen demand (PCOD) from wastewaters in biological film systems. In this context, organic particles that are maintained in suspension (i.e., not removed during normal settling) are the focus of experimentation, modeling, and discussion. The goal of this research project is to study the kinetics of PCOD removal from wastewaters by bacterial films, or biofilms. To achieve this objective, a bench-scale rotating disc biofilm reactor (RDBR) was operated using methanol (dissolved substrate), Min-U-Sil 10 (inorganic particulates), and Maizena corn starch (organic particulates) dissolved/suspended in …

Each teacher participant completed either an electronic or paper version of the Leadership …

Exocellular Polymeric Substances, Bioflocculation And Sludge Settling Properties In A Combined Anaerobic/Activated Sludge Process, Jackeline Luque

LSU New Orleans Theses and Dissertations

Combined anaerobic/aerobic processes for municipal wastewater treatment is quite recent; the studies developed have shown these processes are feasible for the removal of organic, nutrient substances and reduction of sludge produced. Previous studies developed at the Marrero Wastewater pilot plant (fully aerobic system) revealed that the minimum solids contact chamber hydraulic residence (HRT) time in which bioflocculation occurs satisfactorily (effluent SS concentrations < 20 mg/L) is 15 min; however, in the combined anaerobic/aerobic system HRT< 100 minutes resulted in poor floc settling properties and turbid supernatants. Exocellular polymeric substances (EPS) have been found to be the key factor for bioflocculation to occur. Past studies in fully aerobic pilot plant demonstrated that the concentration of EPS increased with mixed liquor concentration and solids retention time. The main purpose of this research is to determine the effect of mixed volatile suspended solids(MLVSS), solids retention time(SRT), and dissolved oxygen(DO) in the production of EPS in the combined anaerobic/ solids contact chamber and its relationship with settling parameters. To carry out the objectives of this investigation three experimental phases were developed : 1) The MLVSS concentration was varied between 1000-4000 mg/l, keeping the SRT and DO as constant as possible 2) The SRT was changed between 2-8 days, keeping the MLVSS concentration between 1500-3500 mg/l and DO between 2-3 mg/l 3) the DO concentration was varied between 0-5mg/l. For a DO of zero, EPS were extracted from the sludge produced in the anaerobic reactor. Analysis of the data showed that the combined system proved to be unstable producing unexpected results such as no clear relationship between MLVSS and EPS. For a DO of zero, no EPS are produced and no flocculation takes place; therefore, effluents with poor quality can be expected from anaerobic treatment units. To meet secondary effluent standards in aeration chamber, capable of promoting the transformation from anaerobic to aerobic biota, and the generation of EPS, high SRT and HRT is required. Under these conditions the system anaerobic/solids contact chamber has an excellent potential for providing secondary treatment for municipal wastewater; nevertheless, the system is not as stable as the conventional aerobic one and bulking problems are common and difficult to content.

Development Of Mass Spectrometric Methods For The Analysis Of Components And Complex Interactions In Biological Systems, Bryan Melvin Ham

LSU New Orleans Theses and Dissertations

The anti-cancer agent 4, 4-dihydroxybenzophenone-2, 4- dinitrophenylhydrazone (A007) forms complexes with pdelocalized lymphangitic dyes that allow its penetration through the skin effectively delivering it to a meta-stable type cancerous site. Previous in vitro studies, combined with gas phase mass spectrometry studies, have shown that a stronger binding affinity equates to a greater efficacy of the drug. For the determination of drug:dye complex binding strength coefficients in solution, two methods have been developed by affinity capillary electrophoresis (ACE), and cation exchange liquid chromatography (CELC). The methods demonstrated that A007 non-covalent binding strength was greatest for methylene green, followed by methylene blue, …

Synthesis And Characterization Of Miniaturized Fluorescence Sensors For Aqueous And Cellular Measurements, Aihui Ma

LSU New Orleans Theses and Dissertations

The objective of this Ph.D. study was to develop new and improved miniaturized particle-based optochemical sensors for the analysis of biological fluid and cellular components. This is highly important because current sensing systems can be biologically toxic and incompatible, invasive, and have limited responsiveness. To accomplish this goal we defined three tasks. The first was to develop lipobead-based sensors for chloride. The halide-specific fluorescence dye, lucigenin, was immobilized into the phospholipid membrane of the lipobeads to enable chloride ion detection. The fluorescence intensity of lucigenin decreases with increasing chloride ion concentration due to dynamic quenching. To stabilize the lipobeads we …

Principals' Perceptions Of The Effectiveness Of Alternatively Certified Teachers In New Orleans Public Schools, Jacquelyn Mahatha

LSU New Orleans Theses and Dissertations

In response to increasing attention to the issues of teacher quality, quantity, and the mandate for highly qualified teachers, alternative approaches to teacher certification have become widespread. Alternative certification allows individuals who typically posses an undergraduate degree in a field other than education to participate in shortened training and/or on- the- job learning experiences that lead to full certification. The number of alternatively certified teachers in urban hard to staff schools is growing. There are many debates as to the effectiveness of alternative certification. At the core of the arguments are issues surrounding teacher pedagogy, classroom management, and knowledge of …

Perceptions Of Low Ses, High Academic Achievement Vietnamese Middle Grades Students Of Factors That Have Contributed To Their School Achievement, Judith Scott

LSU New Orleans Theses and Dissertations

This study examines the perceptions of low socioeconomonic status, high academic achievement Vietnamese middle grades students in the Vietnamese community with respect to the roles that their parents and communities play in supporting academic achievement. Previous research has established the positive relationships between parent involvement and student achievement, and between high SES and student achievement. However, this study explores the perceptions of high achieving middle grades students with low SES. Through focus group discussions and interviews, this study examines student achievement within the theoretical framework of social capital.

An Investigation Of The Relationship Between The Open-Endedness Of Activities And The Creativity Of Young Children, Leng Yan

LSU New Orleans Theses and Dissertations

This study examined the relationship between the open-endedness of activities and the creativity of young children. Eleven prekindergarten classes were observed and rated twice using a researcher-developed instrument, the Open-endedness of Activities Rating Scale (OARS). Three classes were selected from the 11 based on their cumulative ratings in the first observation (CROBS1): the class with the lowest degree of open-endedness of activities (CLSL), the class with a medium degree of openendedness of activities (CLSM), and the class with the highest degree of open-endedness of activities (CLSH). Fifty-two "atrisk" students in these three classes (24 boys, 28 girls), who had no …

Mechanisms Of Magnetic Orientation In Birds, Robert C. Beason

United States Department of Agriculture Wildlife Services: Staff Publications

Behavior and electrophysiological studies have demonstrated a sensitivity to characteristics of the Geomagnetic field that can be used for navigation, both for direction finding (compass) and position finding (map). The avian magnetic compass receptor appears to be a light-dependent, wavelength-sensitive system that functions as a polarity compass (i.e., it distinguishes poleward from equatorward rather than north from south) and is relatively insensitive to changes in magnetic field intensity. The receptor is within the retina and is based on one or more photopigments, perhaps cryptochromes. A second receptor system appears to be based on magnetite and might serve to transduce location …

Law And Neuroscience, Atahualpa Fernandez

ExpressO

Localizing the brain correlates related to moral judgments, using neuroimage techniques (and also studies on brain lesions), seems to be, without doubt, one of the big events in the history of the normative social sciences.The best neuroscientific model of normative judgment available today establishes that the ethical-cerebral law operator counts on, in his neural evaluative-affective systems, a permanent presence of requirements, obligations and strategies, with a “should be” that incorporates internally rational and emotional reasons, that are constitutively integrated in all the activities at the practical, theoretical and normal levels of every process of exercising the law.

Law And Human Nature: The Social-Adaptive Function Of The Normative Behavior, Atahualpa Fernandez

ExpressO

The objective of this article is to offer a critical (re)interpretation of genesis and evolution, object and purpose, as well as useful qualified methods for interpreting, justifying and applying modern practical law, all with the intention of putting philosophic thought and contemporary formal theory of reason at the service of hermeutics and juridical argumentation. Law is no more—no less—than an social-adaptive strategy, evermore complex, but always noticeably deficient, used to articulate argumentatively—in fact, not always with justice—through the virtue of prudence, elementary relational social ties through which men construct approved styles of interaction and social structure, i.e., to organize and …
