Observing, Understanding, And Manipulating Biological Membranes, Ian Mc Cabe

Dissertations - ALL

The phospholipid bilayer is one of the hallmarks of eukaryotic life. This complicated two dimensionally fluid surface is composed of a double layer of lipids which have a region that is hydrophobic and a region that is hydrophilic. The lipid bilayer membranes of a cell act as a barrier that distinguishes the cells and the organelles interiors from the outside environment. In order for the cell to be able to effectively communicate across these impermeable barriers they have evolved many intricate systems of lipid and protein interaction that serve to transmit information from one side of the membrane to the …

Controlling Pseudomonas Aeruginosa Persister Cells By Human Granulocyte Macrophage Colony-Stimulating Factor, Geetika Sanjay Choudhary

Dissertations - ALL

Bacteria are well known to cause chronic infections in humans by entering dormancy and by developing biofilms. These mechanisms allow bacteria to exhibit antibiotic tolerance and relapse to an active virulent state when the antibiotic treatments are discontinued. During bacterial invasions, the host immune cells secrete special signaling proteins, known as cytokines which orchestrate events leading to human immune response and elimination of bacterial pathogens. However, compared to the well documented activities

of cytokines in immune reaction, little is known about the direct effects of cytokines on bacterial cells.

In this study, we focused on granulocyte macrophage colony-stimulating factor (GM-CSF), …

Clinical Probe Utilizing Surface-Enhanced Raman Scattering (Sers) For In-Situ Molecular Imaging Applications, Jeonghwan Kim

LSU Doctoral Dissertations

In this research, a clinical probe utilizing Surface-Enhanced Raman Scattering (SERS) is developed for molecular imaging application which is a visualizing technology to support early diagnosis by providing images in molecular level. In addition to other molecular imaging applications using magnetic resonance, light, and ultrasound, Raman spectroscopy has great potential in terms of non-invasiveness, safety, imaging agent-free, and scanning multiple molecules at a time. However, the critical limitation of Raman spectroscopy using in-vivo molecular imaging application is the inherent low sensitivity of Raman effect. The challenge is overcome by employing SERS enhancing Raman scattering with concentrated electromagnetic oscillation in nanometallic …

Probabilistic Performance-Based Hurricane Engineering (Pbhe) Framework, Vipin Unnithan Unnikrishnan

LSU Doctoral Dissertations

In modern times, hurricanes have caused enormous losses to the communities worldwide both in terms of property damage and loss of life. In light of these losses, a comprehensive methodology is required to improve the quantification of risk and the design of structures subject to hurricane hazard. This research develops a probabilistic Performance-Based Hurricane Engineering (PBHE) framework for hurricane risk assessment. The proposed PBHE is based on the total probability theorem, similar to the Performance-Based Earthquake Engineering (PBEE) framework developed by the Pacific Earthquake Engineering Research (PEER) Center, and to the Performance-Based Wind Engineering (PBWE) framework. The methodology presented in …

Numerical Studies Of Liquid-Liquid Segmented Flows In Square Microchannels Using A Front-Tracking Algorithm, Eamonn Daire Walker

LSU Doctoral Dissertations

Liquid-liquid segmented flows in a square microchannel are investigated numerically using a hybrid front-tracking/front-capturing method. The code is found to be well-adapted to a large range of flow parameters, but droplet flows are limited by poor accuracy at Laplace number above 100 – 1000 and plug flows are limited by the code’s current inability to adequately model the flow in thin films at low capillary numbers. A Schwarz-Aitken acceleration technique is investigated as a means to reduce computation time, but is found not to be advantageous compared to the parallel multigrid formulation of the code. Numerical simulations are divided into …

Experimental Designs For Model Discrimination And Uncertainty Reduction In Groundwater Modeling, Hai Van Pham

LSU Doctoral Dissertations

Groundwater systems are complex and subject to multiple interpretations due to a lack of sufficient information. Different propositions (or alternatives) are often proposed to represent uncertain model components resulted in many conceptual models using the same data. Yet considering too many models may lead to high prediction uncertainty and may lose the purpose of model development. To decrease the prediction uncertainty due to conceptual model uncertainty, two experimental designs are proposed. The first experimental design intends to identify model propositions in each uncertain model component. A discrimination criterion is developed based on posterior model probability. Bayesian model averaging (BMA) is …

Electrochemical Study Of Ammonium Interaction With Au,Sn And Cu Electrodes In Nonaqueous Electrolytes, Guoying Qu

LSU Doctoral Dissertations

Nonaqueous electrolytes play an important role in electrochemical devices such as flip chip and lithium-air batteries. In this work, we examine ammonium-Cu, Sn and Li interactions in nonaqueous electrolytes to optimize the future flip chip flux and electrolyte additive of lithium-air battery. The activity of halogen-free carboxylic acid flux is considered one of the most important aspects in controlling flip chip joint quality recently. CuOx removal effectiveness of carboxylic acid solutions at Cu substrates using electrochemical methods at elevated temperatures from 100ºC to 180ºC is studied thoroughly by chronopotentiometry and gravimetric analysis. Carboxylic acid-based solutions with ethanolamine show oxide removal …

Integrated Sustainability And Resiliency Assessment Methodology For The Design Of Single-Family Residential Structures Subject To Wind And Flood Hazards, Elizabeth Chisolm Matthews

LSU Doctoral Dissertations

Sustainability and resiliency have become important in shaping the criteria in performance-based design objectives in the recent past and will continue to shape future design as climate change impacts and disasters become more prevalent. While much work has been carried out in developing tools to aid in sustainable and resilient performance-based design there is still much work to be done. It is evident that while sustainability and resiliency have mutual advantages there are also inherent conflicts between the two design approaches. Some of the conflict relates to the robustness required of resilient design, which may have higher environmental impacts than …

Product Parameters Optimization For Double Purge Of C-Magma Integrated With Conventional Three-Boiling Crystallization Scheme To Improve Raw Sugar Whole Color, Luz Stella Polanco

LSU Doctoral Dissertations

Efficient crystallization in raw sugar production is the result of a combination of factors and responses that meet specific criteria. Matching a sugar quality standard, maximizing sugar yield, maximizing crystallization equipment capacity and minimizing heat requirement are all necessary optimization criteria. A double centrifugation or purge of C-magma is intended to improve raw sugar whole color by the reduction of color recirculation with the sugar crystal. Combining a three boiling crystallization scheme with a second centrifugation after the last crystallization stage required optimizing the input/output product parameters (purities) and the location of the liquid recycle component (double purge molasses) for …

Chemical Structure And Dynamics In Laminar Flame Propagation, Mohsen Ayoobi

LSU Doctoral Dissertations

The objective of this dissertation is to investigate fundamental aspects of premixed flame structures as well as flame dynamics that arise due to conjugate heat transfer in narrow channels. Laminar premixed combustion simulations in narrow 2D channels show that conjugate heat transfer allows for combustion of mixtures at small scales that are not flammable at normal conditions. To investigate the impact of conjugate heat transfer, preheated 1D cases with premixed H2/Air fuel are simulated for a wide range of operating conditions based on inlet temperature and equivalence ratio. For post-processing, Chemical Explosive Mode Analysis (CEMA, an eigen-analysis technique) is used …

The control scheme was based on three parameters: the rate of change, temperature dead band around the set point to determine heating or cooling, and a jacket fluid clamp temperature. After research and experimentation on actual emulsion polymerization batches it was determined …

Monitoring System For Electric Motors, Sean Waples

Williams Honors College, Honors Research Projects

Induction motors are key to many applications and are one of the most commonly used electric devices. Currently, induction motor fault detection schemes are limited in features and computational power. With current technology, fault detection algorithms are operating in embedded systems and run on embedded processors. These processors do not have the computation power and functionality that more advanced computer systems have, which is the source of the issue. With the recent rise in cloud computing and connected devices, it is possible to build an induction motor monitoring system with a much greater set of features and possibilities.
