Exhibition Next: The Future Of Exhibition Design, Santanu Majumdar Jan 2008

Exhibition Next: The Future Of Exhibition Design, Santanu Majumdar

LSU Master's Theses

ABSTRACT The ubiquitous presence of design guides our day-to-day actions, determining our awareness, configuring our environment, and modifying our lives. We must acknowledge the power and the opportunity of this dynamic force of design. “At the very least,” Peter Lunenfeld says, “design research saves us from reinventing the wheel. At its best, a lively research methodology can reinvigorate the passion that so often fades after designers join the profession.” Lunenfeld inspires me to consider the evolution of exhibition design. My thesis is about the future of exhibition design, enabling me to explore the changes this area of design is now …

Phylogeogaphy Of Nothoprocta Tinamous And The The Phylogeny Of The Tinamidae, Thomas Valqui Jan 2008

Phylogeogaphy Of Nothoprocta Tinamous And The The Phylogeny Of The Tinamidae, Thomas Valqui

LSU Doctoral Dissertations

Understanding how diversity is attained and maintained is one of the central questions in biology. In the Neotropics most attention has centered on the Amazonian lowlands, despite the recognized importance of the role of the Andes in South American diversity. In this dissertation, I address the question by using Nothoprocta tinamous as a model case for examining diversification in the Andes. As a group, they are a manageable size, they exhibit near-restriction to the Andes, they show multi-species parapatric distributions, and they have presumed limited dispersal ability. These are all useful attributes for a system to study speciation and diversification. …

Ethanol Production Using Continuous Multi-Staged Microbe Bioreactors: A Laboratory Study, William Bruce King Jan 2008

Ethanol Production Using Continuous Multi-Staged Microbe Bioreactors: A Laboratory Study, William Bruce King

LSU Master's Theses

Alternative fuels are important for the United States to reduce their dependence on fossil fuels. Currently, ethanol is the only renewable fuel that is produced in commercial quantity. The demand for ethanol is increasing throughout the world. The production of ethanol is limited by the available feedstocks and processing technology. Corn is the primary feedstock for ethanol in the United States. It is processed in either the wet milling or dry milling process. Both processes use either the batch or continuous fermentors. Both batch and continuous systems have operational restrictions with maintaining a good growth of yeast and preventing contamination …

Catalytic Synthesis Of Ethanol From Biomass-Derived Syngas, Adefemi Adelanwa Egbebi Jan 2008

Catalytic Synthesis Of Ethanol From Biomass-Derived Syngas, Adefemi Adelanwa Egbebi

LSU Doctoral Dissertations

Syngas produced by gasification of biomass or coal can be converted directly to ethanol and higher alcohols by processes based on heterogeneous catalysts. Ethanol can be used as a neat fuel or fuel additive or as a hydrogen carrier. Rhodium-based catalysts have been found to be most selective for the formation of C2 oxygenates from the hydrogenation of CO when suitably promoted. Here, we explore the effects of Mn, Fe, and Li promoters on Rh/TiO2. Rh-TiO2, Rh-Li/TiO2, Rh-Mn/TiO2, Rh-Mn-Li/TiO2 and Rh-Mn-Li-Fe/TiO2 catalysts were tested for the hydrogenation of CO …

Concentration Of Phosphorylated Proteins Using Modified Pmma Microanalytical Devices, Jowell Guerra Bolivar Jan 2008

Concentration Of Phosphorylated Proteins Using Modified Pmma Microanalytical Devices, Jowell Guerra Bolivar

LSU Doctoral Dissertations

This work describes the application of PMMA-based microanalytical devices for the affinity-type preconcentration of posttranslational modified proteins (PTMs). The choice of poly(methyl methacrylate), PMMA, is based on its biocompatibility, its functional methyl ester group for potential modification, and its extensive applications to create biological microelectromechanical systems (BioMEMS). Developing methodologies for preconcentration of PTMs is important for cancer diagnosis due to PTMs’ influence in the regulatory mechanism underlying the early stage of apoptosis or regulated cell death. Towards this goal, nitroavidin which can reversibly binds to biotin (and biotinylated proteins), was prepared using reported procedure and was characterized using several techniques …

Novel Methods For The Control Of Phlebotomine Sand Flies (Diptera: Psychodidae), Thomas Michael Mascari Jan 2008

Novel Methods For The Control Of Phlebotomine Sand Flies (Diptera: Psychodidae), Thomas Michael Mascari

LSU Doctoral Dissertations

In arid and semi-arid parts of the Old World, Phlebotomus paptasi is a significant biting pest of man and is the primary vector of Leishmania major, the causative agent of zoonotic cutaneous leishmaniasis (ZCL). Phlebotomus papatasi exhibits a close association with the burrowing rodents that serve as the reservoirs of L. major. Rodent burrows are considered to be the primary habitat of immature P. papatasi in ZCL foci, and sand fly larvae have been observed feeding on rodent feces. In laboratory studies, five insecticides (diflubenzuron, novaluron, methoprene, pyriproxyfen, or ivermectin) were incorporated into the diet of Syrian hamsters and evaluated …

The Zinc Induction Of Heme Oxygenase-1 Gene Promoter In Mouse Hepa Cells, Salim M. Alawneh Jan 2008

The Zinc Induction Of Heme Oxygenase-1 Gene Promoter In Mouse Hepa Cells, Salim M. Alawneh

LSU Doctoral Dissertations

Heme oxygenase-1 (HO-1) catalyzes the initial and rate-limiting reaction in heme catabolism (yielding equimolar quantities of iron, carbon monoxide, and biliverdin), which is further metabolized to bilirubin by biliverdin reductase. HO-1, an important enzyme with antioxidant and cytoprotective properties, functions against oxidative stress generated in response to heme and to various stress stimuli, such as zinc. The cytoprotective function of HO-1 is dependent on both the activities of the reaction products and on the inducibility of the heme oxygenase gene (hmox-1), which is regulated primarily at the level of gene transcription by two distal enhancers, E1 and E2. Characterization of …

Novel Oncolytic Herpesviruses For Breast Cancer Treatment, Anna Israyelyan Jan 2008

Novel Oncolytic Herpesviruses For Breast Cancer Treatment, Anna Israyelyan

LSU Doctoral Dissertations

Oncolytic herpes simplex virus type-1 (HSV-1) has shown great potential as an effective agent for cancer therapy ¨C oncolytic virotherapy. To enhance oncolytic capabilities of previously reported agents, new oncolytic and fusogenic HSV-1 OncSyn and OncdSyn viruses were constructed based on wild type HSV-1 (F) strain. To provide for safety and tumor selectivity, the viruses carried a large deletion including one of the two ¦Ã134.5 genes. The ¦Ã134.5 gene, a major neurovirulence factor, was replaced by a gene cassette constitutively expressing the red fluorescent protein. Homologous recombination was utilized to transfer the fusogenic gBsyn3 mutation to the viral genome to …

Bioanalytical Methods For Studies Of Homocysteine And Novel Cardiovascular Disease Indicators, Arther T. Gates Jan 2008

Bioanalytical Methods For Studies Of Homocysteine And Novel Cardiovascular Disease Indicators, Arther T. Gates

LSU Doctoral Dissertations

This dissertation explores the development of analytical methods for studies of CVD biomarkers and related biomolecular indicators. Initially, spectroscopic studies were conducted to investigate the chemical reactivity of homocysteine (Hcy), an independent CVD risk factor and serological biomarker. Consequently, we proposed an alternate theory for in vivo Hcy clearance based on spontaneous pyridoxal tetrahydrothiazine (PT) formation from Hcy and pyridoxal. The validity of PT-assisted Hcy clearance was further evaluated by use of capillary electrophoretic methods, which allowed rapid monitoring of protein oligomerization in PT-protein reaction mixtures. The results of these studies suggest that PT formation is a plausible mechanism for …

Novel Devices And Protocols Enabling Isolation And Enumeration Of Low Abundant Biological Cells From Complex Matrices, Andre Antonio Adams Jan 2008

Novel Devices And Protocols Enabling Isolation And Enumeration Of Low Abundant Biological Cells From Complex Matrices, Andre Antonio Adams

LSU Doctoral Dissertations

The dimensions of microfluidic devices closely parallel those of biological cells; thusly, they are excellent platforms for the speciation, transport, manipulation, and analysis of cells. Electrokinetic transport of Escherichia coli and Saccharomyces cerevisiae was evaluated in microfluidic devices fabricated in pristine and UV-modified poly(methylmethacrylate) and polycarbonate. The magnitude and direction of transport of the cells was dictated by the buffer composition, conduit surface chemistry, and intrinsic cellular electrical properties. Baker’s yeast in all devices migrated toward the cathode, because of their smaller electrophoretic mobility compared to the electroosmotic flow of the polymer. E. coli cells suspended in 20 mM PBS …

An Evaluation Of The Perceived Obstacles For Policy Officials Regulating The Post Harvest Treatment Of Raw Oysters To Control The Human Health Vibrio Vulnificus Problem, Amy Leah Oestringer

LSU Master's Theses

Vibrio vulnificus is the leading pathogen linked to seafood-associated deaths. This naturally occurring marine bacterium presents a human health risk when it is consumed in raw oysters. Hospitalization is necessary in 90 % Vibrio vulnificus illnesses and 40% end in death. (CDC) Several guidelines and regulations have been enacted to combat this human health issue, but have failed to reduce the steadily rising illness rate. Post-harvest processing requirements for raw oysters could be used to reduce illness rates. A survey was conducted to measure the perceived obstacles that regulators and industry representatives of the raw oyster industry face in policymaking …

A Multi-Scale Assessment Of Den Selection Of Louisiana Black Bears (Ursus Americanus Luteolus) In Northern And Central Louisiana, Annelie Crook Crook Jan 2008

A Multi-Scale Assessment Of Den Selection Of Louisiana Black Bears (Ursus Americanus Luteolus) In Northern And Central Louisiana, Annelie Crook Crook

LSU Master's Theses

Understanding den selection for the Louisiana black bear (Ursus americanus luteolus) may provide insight into habitat requirements of the subspecies and assist in conservation and management efforts. With that goal, I assessed den selection of female Louisiana black bears at multiple spatial scales in northern and central Louisiana. I used 230 den-years to examine den type (tree or ground), microhabitat characteristics at dens, and effects of landscape characteristics on den selection. We also evaluated tree availability and reuse. Solitary and parturient females selected tree dens more frequently (65%) than ground dens. However, tree dens were not required for successful denning …

Species Boundaries, Biogeography, And Intra-Archipelago Genetic Variation Within The Emoia Samoensis Species Group In The Vanuatu Archipelago And Oceania, Alison Madeline Hamilton Jan 2008

Species Boundaries, Biogeography, And Intra-Archipelago Genetic Variation Within The Emoia Samoensis Species Group In The Vanuatu Archipelago And Oceania, Alison Madeline Hamilton

LSU Doctoral Dissertations

Speciation, geographic variation, and genetic differentiation are fundamental processes that generate diversity, and understanding these processes are major goals of evolutionary biology. Evolutionary phenomena may be more observable on islands as compared to continental landmasses as a result of small population sizes, unoccupied niches, and the relative simplicity of island systems and their populations: physical isolation, shorter (and often well documented) geologic time scale, reduced faunal diversity, and lack of outside faunal influence. Yet, despite their incredible diversity, Pacific island faunas have received little research attention relative to other tropical regions. Using molecular data from several species of scincid lizards …

Reciprocal Regulation Of Par-4 And Caspase-8 In The Trail Signaling Pathway, Padhma Ranganathan Jan 2008

Reciprocal Regulation Of Par-4 And Caspase-8 In The Trail Signaling Pathway, Padhma Ranganathan

University of Kentucky Doctoral Dissertations

Par‐4 is a pro‐apoptotic tumor suppressor that is mutated, suppressed or inactivated in cancer. Par‐4 exploits components of the extrinsic pathway to cause apoptosis selectively of cancer cells. This study identified Par‐4 as an essential component of the apoptotic pathway induced by TRAIL, which selectively targets cancer cells. RNA interference‐mediated knockdown of Par‐4 rendered cancer cells unresponsive to TRAIL‐induced apoptosis. Cells with knocked‐down levels of Par‐4 were deficient in the activation of the apoptosis‐initiator caspase‐8 and the apoptosis‐effector caspase‐3 in response to TRAIL. Par‐4 was identified as a critical mediator of membrane translocation of caspase‐8 and the adapter protein FADD. …

Effect Of The SmartstepTm Stabilization System On Balance In Older Adults In An Independent Living Residence, Ann L. Livengood Jan 2008

Effect Of The SmartstepTm Stabilization System On Balance In Older Adults In An Independent Living Residence, Ann L. Livengood

University of Kentucky Doctoral Dissertations

An increase in postural sway is one of the risk factors that have been linked to an increased incidence of falls in the older adult population. Researchers have shown that peripheral sensation is crucial in maintaining a static posture for adults of all ages. It has been reported that older adults have decreased tactile sensation of the plantar surface of their feet. and when the sensory feedback was increased older adults had improved postural control. It was hypothesized that facilitation of the sole of the foot with the use of a semirigid foot orthotic would result in improved postural stability …

Neonatal Respiratory Virus Infection Shapes Pulmonary Function In Adult Mice, Dahui You Jan 2008

Neonatal Respiratory Virus Infection Shapes Pulmonary Function In Adult Mice, Dahui You

LSU Doctoral Dissertations

Respiratory syncytial virus (RSV) and influenza are the two most common causes of acute lower respiratory tract infections in infants. Epidemiological data suggest that both severe RSV and influenza infections during infancy are associated with long-term pulmonary function abnormalities. Despite of the severe burdens of RSV and influenza infections in infants, no efficacious vaccines are available for RSV and the current vaccine strategy for influenza is inconvenient due to the fact that vaccines are made annually based on the prediction of circulating strains in the next season. New strategies in vaccine development have been slow to arrive partly due to …

Comparative Aspects Of The Control Of Posture And Locomotion In The Spider Crab Libinia Emarginata, Andres Gabriel Vidal Gadea Jan 2008

Comparative Aspects Of The Control Of Posture And Locomotion In The Spider Crab Libinia Emarginata, Andres Gabriel Vidal Gadea

LSU Doctoral Dissertations

The study of pedestrian locomotion in crustaceans has largely focused on forward walking macrurans, or sideway walking brachyurans. The spider crab, Libinia emarginata is a brachyuran that, unlike its close relatives, preferentially walks forward. The phylogenetic position, behavioral preference, and amenability to experimental techniques make spider crabs an attractive model for comparative studies of crustacean locomotion. This dissertation looks at the neuroethology of forward walking in L. emarginata. I described the skeletal, muscular, and neural anatomy of the walking machinery of L. emarginata and found adaptations at each level that reflect its walking preference. The ranges of motion of leg …

Strategic Analysis Of Ghana's Wood Export Sector, Odoom Domson Jan 2008

Strategic Analysis Of Ghana's Wood Export Sector, Odoom Domson

LSU Master's Theses

Export-led strategies are very crucial to achieving growth and goals of developing and transition economies such as Ghana. As a result, export strategies are being adopted in many developing countries. Although such export strategies might be in place, the deployment of resources and tax payers’ money involved often calls for the investigation of programs and initiatives that exist and perceptions by industry if they are working. Furthermore, Ghana wood exports to the US, a historically major market, have been declining over the past six years. Therefore, there is the need to determine if export constraints to the US market exist. …
