Biology And Chemical Ecology Of The Sugarcane Beetle And Integrated Pest Management Of Sweet Potato Soil Insects In Louisiana, Tara Parker Smith Jan 2006

Biology And Chemical Ecology Of The Sugarcane Beetle And Integrated Pest Management Of Sweet Potato Soil Insects In Louisiana, Tara Parker Smith

LSU Doctoral Dissertations

Host plant preference and chemical ecology of the sugarcane beetle, Euetheola humilis were evaluated in greenhouse and laboratory studies. Sweet potato, Ipomoea batatas, was significantly preferred over all other plant species evaluated in a host plant preference test. Corn, Zea mays, and sugarcane, Saccharum spp., were the next most chosen plant species in the study. In olfactometer experiments, sugarcane beetles responded significantly more to beetle injured and mechanically injured roots vs. uninjured roots. Male and female beetles were also significantly more attracted to female conspecifics. Differences were not detected between sweet potato cultivars in olfactometer trials. Cultivar preference studies suggested …

Use Of Polyhydroxyalkanoates For Denitrification In Recirculating Aquaculture Systems, Maria Teresa Gutierrez-Wing Jan 2006

Use Of Polyhydroxyalkanoates For Denitrification In Recirculating Aquaculture Systems, Maria Teresa Gutierrez-Wing

LSU Doctoral Dissertations

Increasing demand of aquacultural products is driving the industry toward more intensive culture practices. Aquacultural operations are constrained by limitations on the availability high quality waters and regulatory pressures on the discharges. Recirculating systems can address these issues by reducing the amount of water required in the operation. Closed systems are especially suited where biosecurity is important. In closed systems, nitrate accumulates, limiting the time the water can be reused. In marine inland systems, water reuse reduces the cost of salt for make up water. To increase the water reuse time, some form of nitrate removal process must be incorporated …

The Multiple Dimensions Of The Interfirm Network: The Critical Sources Of Product Innovation, Thongchai Srivardhana Jan 2006

The Multiple Dimensions Of The Interfirm Network: The Critical Sources Of Product Innovation, Thongchai Srivardhana

LSU Doctoral Dissertations

This dissertation examines the impacts of interfirm variables on both invention and commercialization activities, following Greve’s (2003) suggestion that innovation research will be enriched if more studies integrate invention and commercialization activities to understand the entire innovation development process. Utilizing two established theoretical perspectives—organizational learning and institutional theory—six sets of hypotheses are developed containing the following interfirm variables: 1) direct and indirect ties, 2) strength of direct ties, 3) structural holes, 4) prominence of direct partners, 5) exploration and exploitation partners, and 6) horizontal and vertical networks. The dissertation also predicts that these interfirm variables would contribute to either invention …

The Crystal Structure Of A Dna-Binding Protein, Hucr, From Deinococcus Radiodurans R1: A Member Of The Marr Family Of Winged-Helix Transcriptional Regulators, Hansen Bordelon Jan 2006

The Crystal Structure Of A Dna-Binding Protein, Hucr, From Deinococcus Radiodurans R1: A Member Of The Marr Family Of Winged-Helix Transcriptional Regulators, Hansen Bordelon

LSU Doctoral Dissertations

The MarR family of transcriptional regulators is an important group of prokaryotic DNA binding proteins. As the family name implies, multiple antibiotic resistance, members of the MarR family often regulate the expression of resistance genes to multiple antibiotics, organic solvents, household disinfectants, detergents, and oxidative stress agents. Most MarR members act as transcriptional repressors and exist as homodimers in both free and DNA-bound states. DNA-binding is mediated via a winged-helix fold and is often relieved by anionic lipophilic ligands. Deinococcus radiodurans R1 was found to encode a 181 residue MarR homolog designated HucR (hypothetical uricase regulator). Biochemical evidence has shown …

Substrate Utilization In Skeletal Muscle And Adipose Tissue, Lauren M. Sparks Jan 2006

Substrate Utilization In Skeletal Muscle And Adipose Tissue, Lauren M. Sparks

LSU Doctoral Dissertations

Obesity and Type 2 diabetes are associated with high fat diet (HFD), reduced mitochondrial mass and function and insulin resistance as characterized by glucose disposal and relative to body fatness. We hypothesized that (a) HFD affects expression of genes involved in mitochondrial biogenesis and function, (b) carbohydrate metabolism and storage is under transcriptional control and (c) both overall fatness and characteristics of adipose tissue influence the interplay between free fatty acids (FFAs) and insulin-stimulated glucose disposal. To test hypotheses “a” and “b”, we fed 10 insulin-sensitive males an isoenergetic HFD for 3 days with muscle biopsies before and after intervention. …

Numerical Techniques For Fresnel Diffraction In Computational Holography, Richard Patrick Muffoletto Jan 2006

Numerical Techniques For Fresnel Diffraction In Computational Holography, Richard Patrick Muffoletto

LSU Doctoral Dissertations

Optical holography can produce very realistic virtual images due to its capability to properly convey the depth cues that we use to interpret three-dimensional objects. Computational holography is the use of digital representations plus computational methods to carry out the holographic operations of construction and reconstruction. The large computational requirements of holographic simulations prohibit present-day existence of real-time holographic displays comparable in size to traditional two-dimensional displays. Fourier-based approaches to calculate the Fresnel diffraction of light provide one of the most efficient algorithms for holographic computations because this permits the use of the fast Fourier transform (FFT). The limitations on …

Factors Influencing The Importance Of Incorporating Competencies Regarding Mass Casualty Incidents Into Baccalaureate-Degree Nursing Programs As Perceived By Currently Employed Faculty, Kristin Whitty Jan 2006

Factors Influencing The Importance Of Incorporating Competencies Regarding Mass Casualty Incidents Into Baccalaureate-Degree Nursing Programs As Perceived By Currently Employed Faculty, Kristin Whitty

LSU Doctoral Dissertations

Whether they are naturally occurring, caused by environmental forces, or generated by humans, disasters have placed extraordinary stresses on society. Following September 11, 2001, the Department of Homeland Security was created to protect the nation and coordinate responses to future emergencies at the federal, state, and local levels. However, Governmental agencies can’t handle all aspects of mass casualty events. Healthcare professionals, such as nurses, who are knowledgeable and trained in mass casualty incidents (MCIs) are needed to provide competent care to the victims. Although others expect a knowledgeable nursing response, the majority of nurse educators have not received mass casualty …

Investigating The Influence Of Anti-Racist Education In Achieving Prejudice Reduction Among Secondary Education Students, Joseph Edward Wilson Jan 2006

Investigating The Influence Of Anti-Racist Education In Achieving Prejudice Reduction Among Secondary Education Students, Joseph Edward Wilson

LSU Doctoral Dissertations

This dissertation investigates the influence of participation in an anti-racist educational (ARE) program upon the perceptions of, critical assessments of, and self-reported behaviors toward institutional racism in a sample of 11th-grade students enrolled in a public school district that had recently undergone compulsory, court-ordered desegregation. This quasi-experimental study measured hypothesized differences between the scores of a group of high school students on a quantitative data-gathering instrument before their participation in an Undoing Racism curriculum, with their scores on that same instrument re-administered three months after their completion of that course. It then compared the degree of pre-intervention/ post-intervention changes in …

Loss Of Escape-Related Giant Neurons In A Spiny Lobster, Panulirus Argus, Sandra Y. Espinoza, Lana Breen, Nisha Varghese, Zen Faulkes Jan 2006

Loss Of Escape-Related Giant Neurons In A Spiny Lobster, Panulirus Argus, Sandra Y. Espinoza, Lana Breen, Nisha Varghese, Zen Faulkes

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

When attacked, many decapod crustaceans perform tailflips, which are triggered by a neural circuit that includes lateral giant interneurons, medial giant interneurons, and fast flexor motor giant neurons (MoGs). Slipper lobsters (Scyllaridae) lack these giant neurons, and it has been hypothesized that behavioral (e.g., digging) and morphological (e.g., flattening and armor) specializations in this group caused the loss of escape-related giant neurons. To test this hypothesis, we examined a species of spiny lobster, Panulirus argus. Spiny lobsters belong to the sister taxon of the scyllarids, but they have a more crayfish-like morphology than scyllarids and were predicted to have escape-related …

Roles Of Intra-Fruit Oxygen And Carbon Dioxide In Controlling Pepper (Capsicum Annuum L.) Seed Development And Storage Reserve Deposition, J. Blasiak, Anxiu Kuang, Chakavak S. Farghangi, M. E. Musgrave

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Seeds developing within a locular space inside hollow fruit experience chronic exposure to a unique gaseous environment. Using two pepper cultivars, `Triton' (sweet) and `PI 140367' (hot), we investigated how the development of seeds is affected by the gases surrounding them. The atmospheric composition of the seed environment was characterized during development by analysis of samples withdrawn from the fruit locule with a gas-tight syringe. As seed weight plateaued during development, the seed environment reached its lowest O2 concentration (19%) and highest CO2 concentration (3%). We experimentally manipulated the seed environment by passing different humidified gas mixtures through the fruit …

Effects Of An External Field And Dissipation On Decoherence, Jian Zuo Jan 2006

Effects Of An External Field And Dissipation On Decoherence, Jian Zuo

LSU Doctoral Dissertations

Decoherence is the suppression of the interference of quantum states. It plays important roles in the study of the quantum-classical transition. It is also the major obstacle in the implementation of various schemes of quantum computers. Decoherence can be affected by many factors. The interactions between quantum systems of interest and dissipative environments cause the extensively studied environment-induced-decoherence. Decoherence can also occur as the result of a temperature effect. A recent experiment investigated the engineering of decoherence, which involves applying an external field to the quantum system. In this thesis, we study the effect of an external field on decoherence …

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li Jan 2006

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li

LSU Doctoral Dissertations

In herd health studies, the mixed effects logistic regression model with random herd effects are commonly used for modeling clustered binary data. These models are well developed and widely used in the literature, among which is the logistic-normal regression model. In contrast to the rich literature in modeling methods, the sample size/power analysis methods for such mixed effects models are sparse. The sample size/power analysis method for the logistic-normal regression model is not readily available. This study is to develop a power analysis/sample size estimation method for the logistic-normal regression model. Extended from the sample size method for the likelihood …

Comparing Mothers And Fathers On Acceptability Of Parent-Training Approaches, Knowledge Of Behavioral Principles, And Parenting Behaviors, Jennifer D. Tiano Jan 2006

Comparing Mothers And Fathers On Acceptability Of Parent-Training Approaches, Knowledge Of Behavioral Principles, And Parenting Behaviors, Jennifer D. Tiano

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although most child research is conducted with mothers as the primary source of data, results often are applied to fathers. Yet, mothers and fathers engage in different interactions with children and may have varying attitudes and knowledge of parenting. This project compared mothers and fathers on a variety of parenting measures. Participants included a community sample of 80 parents (40 mother-father pairs) and their male child between the ages of two and seven. This study evaluated potential differences between mothers and fathers on treatment acceptability, knowledge of behavioral principles, and observed parenting behaviors. Results indicated that mothers prefer response cost …

Evalutation Of Sediment-Sensitive Biological Metrics As Bio-Monitoring Tools On Varied Spatial Scales, Janna Yvonne Smithey Owens

All ETDs from UAB

Sediment is one of the principal causes of water-quality impairment in surface waters of the United States. Although biological assessments are useful for characterizing the status of aquatic communities, reasons for impairment cannot be identified without quantifying associated variables physical variables that can be adequately related to bio-logical functions. Our objective was to explore potential relations between fish and ben-thic macroinvertebrate community structures and variables of sedimentation processes on a watershed and channel-reach scale. Biologic collections and habitat evaluations were conducted using the EPA’s Rapid Bioassessment Protocol over a period of three years (2000-2003) at sites in the upper Cahaba …

Increased Hexosamine Biosynthesis And Protein O-Glcnac Protect Isolated Rat Heart From Ischemia/Reperfusion Injury, Jia Liu Jan 2006

Increased Hexosamine Biosynthesis And Protein O-Glcnac Protect Isolated Rat Heart From Ischemia/Reperfusion Injury, Jia Liu

All ETDs from UAB

Increased levels of protein-associated O-linked N-acetylglucosamine (O-GlcNAc) have been correlated with increased tolerance to stress. Therefore the goal of this study was to determine whether enhanced flux through the hexosamine biosynthesis pathway (HBP), which leads to elevated levels of O-GlcNAc, increased the tolerance of the heart to ischemia and reperfusion (I/R). Hearts from male rats were isolated and perfused with Krebs-Henseliet buffer containing 5mM glucose, and global, no-flow ischemia was induced for 20min followed by 60 min reperfusion. 20 min pre-treatment with 10 mM glucosamine, which enters the HBP directly, significantly improved functional recovery and decreased cardiac Troponin I release …

Regulation Of Ss-Catenin By Gli1 In Epithelial Transformation, Xingnan Li Jan 2006

Regulation Of Ss-Catenin By Gli1 In Epithelial Transformation, Xingnan Li

All ETDs from UAB

Gli family members-mediated continuous Hedgehog (Hh) pathway activity plays a role in the growth of a number of human cancers, including the common malignancy of skin, basal cell carcinoma (BCC), and other highly aggressive tumor types. However, the mechanism by which Gli proteins act to promote the outgrowth of cancer in response to stimulation of Hh signaling is poorly understood. Identified as zinc finger transcriptional factors, the Gli family of proteins has been shown to be involved in multiple cellular processes through activating its target genes. Therefore, to study the function of Gli target genes is important for our understanding …

Klf4 Regulates Notch1 Expression And Signaling During Epithelial Transformation, Zhaoli Liu Jan 2006

Klf4 Regulates Notch1 Expression And Signaling During Epithelial Transformation, Zhaoli Liu

All ETDs from UAB

Notch1 and KLF4 function in the specification of epithelial cell fates, and each can act as a context-dependent oncogene or tumor suppressor. We report that KLF4 directly regulates transcription of Notch1 and that cleavage of full-length Notch1 to the active intracellular form, N1IC, is necessary for transformation by KLF4. Paradoxically, KLF4 suppresses canonical Notch1-CSL signaling by up-regulating Hairless, an antagonist of this pathway. Dominant-negative inhibitors of the canonical Notch1 signaling pathway do not block transformation of epithelial cells by KLF4, while they greatly reduce the efficiency of transformation by N1IC. Thus, N1IC can transform cells by two distinct mechanisms: the …

The Influence Of Retroviral Codon Usage On The Acquisition Of The Trna Used To Prime Reverse Transcription, Matthew T. Palmer Jan 2006

The Influence Of Retroviral Codon Usage On The Acquisition Of The Trna Used To Prime Reverse Transcription, Matthew T. Palmer

All ETDs from UAB

An essential step in retrovirus replication is the conversion of the genomic-length viral RNA into a DNA copy, a reaction which is catalyzed by reverse transcriptase and primed by a host cell tRNA. The nearly continuous association of tRNA with the various components of translation, as well as the severely limited time in which a tRNA molecule spends in an uncharged state, constitute seemingly formidable barriers to the acquisition and use of host cell tRNA as primers. The mechanism by which retroviruses acquire this implausible primer are unknown. Naturally occurring isolates of most retrovirus species show a conserved use of …

Intestinal Peptides And Ethnic Differences In Insulin Secretion, Paul B. Higgins Jan 2006

Intestinal Peptides And Ethnic Differences In Insulin Secretion, Paul B. Higgins

All ETDs from UAB

African Americans (AA) exhibit greater insulin responses following either an oral or intravenous glucose challenge relative to their European American (EA) counterparts. The etiology of this difference is not fully understood nor has it been confirmed with a more physiologically relevant mixed meal. Insulin secretion is regulated by a variety of factors. Significant among these are the enteric peptides glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). The role of the incretin system in the ethnic differences in post challenge insulinemia has received little attention. Hence, the purpose of the study was two-fold. First, determine whether AA have higher fasting …

Surface Reconstruction Using Gamma Shapes, Ying Sun Jan 2006

Surface Reconstruction Using Gamma Shapes, Ying Sun

All ETDs from UAB

Surface reconstruction from a set of sample points is important in many applications, including computer graphics, reverse engineering, computer vision and medical imaging. In this dissertation, several surface reconstruction techniques are investigated and the Alpha Shapes method is studied in detail. A new method, called Gamma Shapes, is introduced and implemented for reconstructing surfaces from a set of unorganized sample points. The Alpha Shapes method requires that the data point set be uniformly sampled in order to reconstruct an acceptable surface. Gamma Shapes method is an extension of the Alpha Shapes method with the advantage that the Gamma Shapes method …
