Analysis Of Soil And Groundwater Microbial Population Dynamics At In Situ Bioremediation Sites In California And Texas, Farrar C. Stewart Jan 2014

Analysis Of Soil And Groundwater Microbial Population Dynamics At In Situ Bioremediation Sites In California And Texas, Farrar C. Stewart

LSU Master's Theses

Traditional methods for assessing in situ microbial communities often provide limited information on substrate utilization in bioremediation processes. The goal of this research was to assess new methods for describing the microbial communities found in the groundwater and affected contaminated soils documenting changes in community structure, population dynamics, substrate utilization and biodegradation of constituents of concern (CoC) during a site remediation. Two in situ bioremediation pilot studies using biological plugs are being conducted, one in the California San Francisco Bay Area (Sunnyvale) and one in the East Texas Piney Woods (Longhorn). The hypothesis is that changes in community structure, population …

Bioavailability Of Alpha-Tocopherol Entrapped In Poly (Lactide-Co-Glycolide) (Plga) And Plga-Chitosan Nanoparticles, Lacey Caroline Simon Jan 2014

Bioavailability Of Alpha-Tocopherol Entrapped In Poly (Lactide-Co-Glycolide) (Plga) And Plga-Chitosan Nanoparticles, Lacey Caroline Simon

LSU Master's Theses

Alpha-tocopherol (áT) is a hydrophobic, antioxidant molecule shown to prevent or retard the effects of free radicals associated with diseases. It is hypothesized that the bioavailability of áT can be improved when entrapped in PLGA (Poly lactide-co-glycolide) and PLGA-Chi (PLGA-Chitosan) nanoparticles and that the mucoadhesive properties of chitosan may enhance absorption more than PLGA alone. PLGA and PLGA-Chi NPs synthesized with PVA as surfactant were characterized by measuring entrapment efficiency, size, PDI, and zeta potential when suspended in DI water. Nanoparticle physical stability was evaluated via NP exposure to environmental pH ranging from 2.5-9. Chemical stability of entrapped áT was …

Human Perception Of Piano Timbre Variations Relative To The Piano's Dynamic Range, Pitagoras Goncalves Jan 2014

Human Perception Of Piano Timbre Variations Relative To The Piano's Dynamic Range, Pitagoras Goncalves

LSU Doctoral Dissertations

The purpose of this study was to investigate the perception of brightness as it relates to loudness variations in piano tone. A single note was recorded with multiple intensities and used as the stimuli. I normalized all recorded notes to be perceived with the same volume and with the same duration. Consequently, the tone quality could be evaluated without the influence of loudness. Professional musicians and music students were invited to participate. I designed a mechanical apparatus, which produced a measured amount of force applied to the piano key. This device was used to record an intensity range of approximately …

Untangling Earth System Responses Recorded In Sulfate's Sulfur And Oxygen Isotopes At The Dawn Of Multicellular Life And Today, Bryan Alan Killingsworth Jan 2014

Untangling Earth System Responses Recorded In Sulfate's Sulfur And Oxygen Isotopes At The Dawn Of Multicellular Life And Today, Bryan Alan Killingsworth

LSU Doctoral Dissertations

Major Earth system perturbations in the deep past and today are recorded in sulfate sulfur and oxygen isotopes, as examined here in three cases. (1) Sedimentary sulfate record of the “Marinoan Oxygen-17 Depletion” (MOSD) event, implies ultra-high CO2 atmosphere at ~635 Ma after global glaciation. MOSD duration is constrained by correlating its most complete record to radiometric dates. Barium sulfate layers in South China sediments show the MOSD in lower layers but persistently absent up section. Carbon-13 correlation locates the MOSD within dated intervals from other sites, yielding a 0 - 0.99 Myr duration. Thus, sedimentary constraint on this non-steady-state …

Characterization Of A Water Soluble, Non-Ionic, Helical Poly(Α-Amino Acid), Wayne Huberty Jan 2014

Characterization Of A Water Soluble, Non-Ionic, Helical Poly(Α-Amino Acid), Wayne Huberty

LSU Doctoral Dissertations

A water soluble, non-ionic, rodlike polymer, PEGL, was synthesized and characterized in efforts to synthesize a novel model polymer to study stiff polymers in solution. The rodlike system is likely stiff due to a high relative percent helicity in water up to 50 °C, measured by circular dichroism, the observation of liquid crystalline domains in water, and from the slope measured from conformation plots supplied by GPC/MALS; however, it also apparent the system is aggregating in both a 2 mM azide solution and a buffer (200 mM NaNO3 + 20 mM NaH2PO4 + 2 mM NaN3), in corroboration of negative …

A Standardized Ultrasonography Classification For Channel Catfish Ovarian Development, Noel D. Novelo Jan 2014

A Standardized Ultrasonography Classification For Channel Catfish Ovarian Development, Noel D. Novelo

LSU Doctoral Dissertations

The goal of this dissertation was to develop application of ultrasonography as a decision-making tool in genetic improvement programs for channel catfish Ictalurus punctatus. A literature review on the use of ultrasonography in fish reproduction generated a comprehensive reference data set intended to benefit existing and potential users. It exposed the need for reporting of instrument control settings and standardization of fish handling and imaging procedures. These issues were addressed from the onset of this work by assessing more than 6,300 channel catfish ovaries by use of initial fish handling and imaging procedures developed (2004-2005) at the Louisiana State University …

Pharmacy Faculty Articles and Research

Src kinase, a prototype member of the Src family of kinases (SFKs), is over-expressed in various human tumors, and has become a target for anticancer drug design. In this perspective, a series of eighteen 2-pyridone derivatives were synthesized and evaluated for their c-Src kinase inhibitory activity. Among them, eight compounds exhibited c-Src kinase inhibitory activity with IC50 value of less than 25 mu M. Compound 1-[2-(dimethylamino)ethyl]-5-(2-hydroxy-4-methoxybenzoyl)pyridin-2(1H)-one (36) exhibited the highest c-Src kinase inhibition with an IC50 value of 12.5 mu M. Furthermore, the kinase inhibitory activity of compound 36 was studied against EGFR, MAPK and PDK, however no significant activity …

Fatherhood In Brazil, Bangladesh, Russia, Japan, And Australia, David W. Shwalb, Barbara J. Shwalb Jan 2014

Fatherhood In Brazil, Bangladesh, Russia, Japan, And Australia, David W. Shwalb, Barbara J. Shwalb

Online Readings in Psychology and Culture

This article illustrates that the roles of fathers are highly variable and context-dependent. Research data from five diverse societies (Brazil, Bangladesh, Russia, Japan, and Australia) show that fathers, fathering, and fatherhood differ within societies according to eight types of contextual influence. Examples are provided of each contextual factor: (1) geographical location (e.g., dispersion of fathers across huge land masses in Russia and Australia; impact of dense populations in Japan and Bangladesh); (2) long-term historical legacies (centuries of patriarchy in Brazil) and short-term historical events (fall of communism in Russia); (3) family characteristics (joint, extended families of Bangladesh; small Japanese families); …

Exploring The Role Of Parents In Supporting Recreational Book Reading Beyond Primary School, Margaret K. Merga Jan 2014

Exploring The Role Of Parents In Supporting Recreational Book Reading Beyond Primary School, Margaret K. Merga

Research outputs 2014 to 2021

Levels of aliteracy have been found to rise in adolescence, and this article explores the potential influence of parents on this trend. The views of adolescent students who took part in semi-structured interviews for the West Australian Study in Adolescent Book Reading (WASABR) provide insight into how parental support may change in the adolescent years. Student perspectives support earlier findings that there is an expiration of parental encouragement in many cases, though this sometimes occurs as children are avid readers and thus the support is no longer deemed necessary. The experiences of students with parents who provided continued encouragement into …

Altered Cytological Parameters In Buccal Cells From Individuals With Mild Cognitive Impairment And Alzheimer's Disease, Maxime François, Wayne Leifert, Jane Hecker, Jeffrey Faunt, Ralph Martins, Philip Thomas, Michael Fenech

Research outputs 2014 to 2021

Previous studies have shown that mild cognitive impairment (MCI) may be reflective of the early stages of more pronounced neurodegenerative disorders such as Alzheimer's disease (AD). There is a need for a minimally invasive and inexpensive diagnostic to identify those who exhibit cellular pathology indicative of MCI and AD risk so that they can be prioritized for primary preventative measures. The hypothesis was that a minimally invasive approach using cytological markers in isolated buccal mucosa cells can be used to identify individuals of both MCI and AD. An automated buccal cell assay was developed using laser scanning cytometry (LSC) to …

Research outputs 2014 to 2021

Dissolved cobalt (DCo; 0.2μm; 10%) to the DCo stock of the mixed layer in the equatorial and north subtropical domains. Biotic and abiotic processes as well as the physical terms involved in the biogeochemical cycle of Co were defined and estimated. This allowed establishing the first global budget of DCo for the upper 100m in the western Atlantic. The biological DCo uptake flux was the dominant sink along the section, as reflected by the overall nutrient-type behavior of DCo. The regeneration varied widely within the different biogeochemical domains, accounting for 10% of the DCo-uptake rate in the subarctic gyre and …

Higher Breakfast Glycaemic Load Is Associated With Increased Metabolic Syndrome Risk, Including Lower Hdl-Cholesterol Concentrations And Increased Tag Concentrations, In Adolescent Girls, Analise Nicholl, Mary Du Heaume, Trevor A. Mori, Lawrence J. Beilin, Wendy H. Oddy, Alexandra P. Bremner, Therese A. O'Sullivan

Research outputs 2014 to 2021

Almost all previous studies examining the associations between glycaemic load (GL) and metabolic syndrome risk have used a daily GL value. The daily value does not distinguish between peaks of GL intake over the day, which may be more closely associated with the risk of the metabolic syndrome. The aim of the present study was to investigate the cross-sectional associations between daily and mealtime measures of GL and metabolic syndrome risk, including metabolic syndrome components, in adolescents. Adolescents participating in the 14-year follow-up of the Western Australian Pregnancy Cohort (Raine) Study completed 3 d food records and metabolic assessments. Breakfast …

Motherless Mothers: Maternally Bereaved Women In Their Everyday Roles As Mothers, Bethwyn Rowe, Bronwyn A. Harman

Research outputs 2014 to 2021

Motherless mothers are women who lose their mothers to death prior to having their children, and therefore raise their children without the maternal support and guidance afforded to many women whose mothers are still alive (Edelman, 2006). A qualitative research design was used to gain an in-depth understanding of the everyday experiences faced by motherless mothers. Semi-structured, in-depth interviews were conducted with 10 motherless mothers. Four major themes emerged including grief, support, absence of knowledge, and changes to self following loss. Results provide insight into the ongoing influence a mother's death can have on a daughter's life and draw distinction …

Undergraduate Perceptions Of The Development Of Team-Working Skills, Denise Jackson, Ruth Sibson, Linda Riebe Jan 2014

Undergraduate Perceptions Of The Development Of Team-Working Skills, Denise Jackson, Ruth Sibson, Linda Riebe

Research outputs 2014 to 2021

Purpose: The ability to working effectively with others (WEWO) is critical yet industry continues to lament deficiencies in new graduates. Progress in developing this highly valued skill in undergraduates is impeded by a lack of conceptual clarity and evidence of how best to measure it, and a tendency to adopt an outcomes-focused, rather than process-oriented, approach. This paper aims to investigate undergraduate perceptions of how well a stand-alone employability skill development programme, operating in an Australian Business Faculty, is fostering the WEWO skill set and which pedagogical practices are considered to add most value. Design/methodology/approach: The study examines undergraduate perceptions …

A Day In The Park: Emerging Genre For Readers Of Aboriginal English, Ian G. Malcolm Jan 2014

A Day In The Park: Emerging Genre For Readers Of Aboriginal English, Ian G. Malcolm

Research outputs 2014 to 2021

Despite the fact that varieties of Aboriginal English are widely used in communication in Aboriginal communities across Australia, the use of Aboriginal English in writing has been limited. A significant genre for Aboriginal writers has been the autobiographical narrative. In most published narratives of this genre, Aboriginal English has not been widely used. This paper describes and discusses an autobiographical narrative composed by Aboriginal author Glenys Collard and published by the Western Australian Department of Training and Workforce Development in 2011 in which the only medium of narration (except for utterances by non-Aboriginal characters) is Aboriginal English. Analysis of this …

The Use Of Unregulated Staff: Time For Regulation?, Christine M. Duffield, Di E. Twigg, Judith D. Pugh, Gemma Evans, S Dimitrelis, Michael A. Roche

Research outputs 2014 to 2021

Internationally, shortages in the nursing workforce, escalating patient demands, and financial constraints within the health system have led to the growth of unlicensed nursing support workers. Recently, in relation to the largest publicly funded health system (National Health Service), it was reported that extensive substitution of registered nurses with unskilled nursing support workers resulted in inadequate patient care, increased morbidity and mortality rates, and negative nurse outcomes. We argue that it is timely to consider regulation of nursing support workers with their role and scope of practice clearly defined. Further, the addition of these workers in a complementary model of …

Liminal Experience Of East Asian Backpackers, Huong T. Bui, Hugh Wilkins, Y S. Lee Jan 2014

Liminal Experience Of East Asian Backpackers, Huong T. Bui, Hugh Wilkins, Y S. Lee

Research outputs 2014 to 2021

Acknowledging the increasing popularity of independent travel from East Asia, this article explores the backpacking experience of young travellers of the region, from a socio-anthropological angle. Using liminality theory as a guideline and adopting a qualitative investigative approach, 31 interviews with East Asian backpackers were conducted. The findings suggest there are dual facets of the liminal experiences of the backpackers. On one hand, young travellers were motivated to escape from temporal, spatial and social pressures at home. On the other, their narratives reflected a strong commitment to home through a sense of filial piety, an awareness of their identity and …

Identification Of Unknowns Within A Probabilistic System: The Diagnostic Value Of Attributes, D W. Goodall Jan 2014

Identification Of Unknowns Within A Probabilistic System: The Diagnostic Value Of Attributes, D W. Goodall

Research outputs 2014 to 2021

Using a data base underpinned by probability considerations in which a variety of attributes, some of which may be quantitative, are recorded for a number of “operational taxonomic units” (OTUs), a key system is described by which an unnamed specimen may quickly be identified. The concept of “diagnostic power” is introduced, by which each attribute is evaluated in terms of its potential contribution to identifying the unnamed specimen. Besides coverage of different types of attributes and the introduction of “diagnostic power”, the system has the advantages of incorporating multiple values of an attribute for each OTU and offering short-cuts to …

Self-Assessment Of Employability Skill Outcomes Among Undergraduates And Alignment With Academic Ratings, Denise Jackson Jan 2014

Self-Assessment Of Employability Skill Outcomes Among Undergraduates And Alignment With Academic Ratings, Denise Jackson

Research outputs 2014 to 2021

Despite acknowledgement of the benefits of self-assessment in higher education, disparity between student and academic assessments, with associated trends in overrating and underrating, plagues its meaningful use, particularly as a tool for formal assessment. This study examines self-assessment of capabilities in certain employability skills in more than 1000 Australian business undergraduates. It evaluates the extent to which student self-assessments differ from academics, in what ways and the influence of certain individual and background characteristics - such as stage of degree, gender and academic ability - on rating accuracy. Explanations for documented disparities are presented, in addition to implications and strategies …

The Acquisition Of Expertise In The Classroom: Are Current Models Of Education Appropriate?, Craig P. Speelman Jan 2014

The Acquisition Of Expertise In The Classroom: Are Current Models Of Education Appropriate?, Craig P. Speelman

Research outputs 2014 to 2021

The study of expertise tends to focus on humans who can perform extraordinary feats. Although the way in which expertise is acquired is often characterized as similar to everyday skill acquisition, the attainment of basic numeracy skills is rarely considered in the same context as the attainment of expertise. It is clear, though, that average numeracy skills possess all the hallmarks of expert performance. In this paper I argue that the traditional classroom of Western education systems pays insufficient attention to the idea that effective numeracy skills represent a level of expertise that requires a particular form of training. Using …

Characterizing The Resolvability Of Real Superluminescent Diode Sources For Application To Optical Coherence Tomography Using A Low Coherence Interferometry Model, Paul V. Jansz, Steven Richardson, Graham Wild, Steven Hinckley Jan 2014

Characterizing The Resolvability Of Real Superluminescent Diode Sources For Application To Optical Coherence Tomography Using A Low Coherence Interferometry Model, Paul V. Jansz, Steven Richardson, Graham Wild, Steven Hinckley

Research outputs 2014 to 2021

The axial resolution is a critical parameter in determining whether optical coherent tomography (OCT) can be used to resolve specific features in a sample image. Typically, measures of resolution have been attributed to the light source characteristics only, including the coherence length and the point spread function (PSF) width of the OCT light sources. The need to cost effectively visualize the generated PSF and OCT cross-correlated interferogram (A-scan) using many OCT light sources have led to the extrinsic evolution of the OCT simulation model presented. This research indicated that empirical resolution in vivo, as well as depending on the light …

Regulation Of Human Pax6 Expression By Mir-7, M Needhamsen, Robert B. White, Keith M. Giles, Sarah A. Dunlop, Meghan G. Thomas Jan 2014

Regulation Of Human Pax6 Expression By Mir-7, M Needhamsen, Robert B. White, Keith M. Giles, Sarah A. Dunlop, Meghan G. Thomas

Research outputs 2014 to 2021

The paired box gene 6 (PAX6) is a powerful mediator of eye and brain organogenesis whose spatiotemporal expression is exquisitely controlled by multiple mechanisms, including post-transcriptional regulation by microRNAs (miRNAs). In the present study, we use bioinformatic predictions to identify three candidate microRNA-7 (miR-7) target sites in the human PAX6 3′ untranslated region (3′-UTR) and demonstrate that two of them are functionally active in a human cell line. Furthermore, transient transfection of cells with synthetic miR-7 inhibits PAX6 protein expression but does not alter levels of PAX6 mRNA, suggesting that miR-7 induces translational repression of PAX6. Finally, a comparison of …

Setting Goals And Choosing Appropriate Reference Sites For Restoring Mine Pit Lakes As Aquatic Ecosystems: Case Study From South West Australia, Eddie J. Van Etten, C. D. Mccullough, Mark A. Lund

Research outputs 2014 to 2021

Pit lakes may form when open cut mining leaves a pit void behind that fills with ground and surface water. Often replacing terrestrial ecosystems that existed prior to mining, the pit lake may offer an alternative ecosystem with aquatic biodiversity values that can be realised through planned restoration. Restoration theory and mine closure regulatory requirements guides us toward restoring disturbed systems towards landscapes that are of regional value and relevance. However, how do we identify a restoration target for a novel aquatic habitat that did not exist prior to the new post-mining landscape? This paper presents a process of first …
