Thermodynamics Of Dna Binding By Dna Polymerase I And Reca Recombinase From Deinococcus Radiodurans, Jaycob Dalton Warfel Jan 2014

Thermodynamics Of Dna Binding By Dna Polymerase I And Reca Recombinase From Deinococcus Radiodurans, Jaycob Dalton Warfel

LSU Doctoral Dissertations

Deinococcus radiodurans has a significantly more robust DNA repair response than Escherichia coli, which helps it survive high amounts of oxidative stress. D. radiodurans DNA Polymerase I (DrPolI) and RecA protein (DrRecA) play essential parts in this DNA repair capability. Structural stability studies of the DrPolI large fragment (Klendra) and examination of the DNA binding characteristics of Klendra and RecA are presented herein. In the absence of cofactors DrRecA binds to dsDNA more than 20 fold tighter than EcRecA, and binds ssDNA up to 9 fold tighter. Binding to dsDNA in the absence of cofactor presumably monitors DNA end binding. …

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 …

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 …

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 …

No Taste For Health: How Tastes Are Being Manipulated To Favour Foods That Are Not Conducive To Health And Wellbeing, Lelia R. Green Jan 2014

No Taste For Health: How Tastes Are Being Manipulated To Favour Foods That Are Not Conducive To Health And Wellbeing, Lelia R. Green

Research outputs 2014 to 2021

Background : “The sense of taste,” write Nelson and colleagues in a 2002 issue of Nature, “provides animals with valuable information about the nature and quality of food. Mammals can recognize and respond to a diverse repertoire of chemical entities, including sugars, salts, acids and a wide range of toxic substances” (199). The authors go on to argue that several amino acids—the building blocks of proteins—taste delicious to humans and that “having a taste pathway dedicated to their detection probably had significant evolutionary implications”. They imply, but do not specify, that the evolutionary implications are positive. This may be the …
