Characterization of Wear and Dynamic Performance of Interstage Seals for Electric Submersible Pumps
(2019-02-22)
Electric Submersible Pumps (ESPs) increase head of process fluid in oil production from within the well. An ESP comprises of a pump, seal, and motor section oriented vertically. The pump section includes multiple centrifugal ...
The Development of an Ion Mobility-Orbitrap Mass Spectrometer for the Analysis of Large Proteins and Protein Complexes
(2019-04-05)
Ion mobility-mass spectrometry (IM-MS) is a powerful technique that provides a nested size-and-charge in mass-to-charge analysis in the gas-phase; however, current instrumentation is limited in resolution, both in mobility ...
Building Energy Simulation Using Constrained Optimization
(2019-03-29)
This thesis presents an equation-based approach to steady state building energy modeling using constrained optimization. Models using this approach can be built from algebraic equations that describe a building and its ...
Electromagnetic Probe and Driving Circuit Design for Micro Magnetic Stimulation of Small Animal Brains
(2019-04-18)
Magnetic stimulation is becoming more and more popular recently as a kind of medical treatment for brain function. By generating an alternating magnetic field from the electromagnetic probe, the induced electric field will ...
The Crucial Roles of JMJD3 in T Cell Trafficking and Persistence
(2019-03-28)
Jmjd3, a histone H3K27 demethylase, regulates macrophage and T-cell differentiation, but its role in T-cell trafficking and persistence remains largely unknown. In this dissertation, I show that Jmjd3 deficiency in CD4^+ ...
Identification, Validation, and Structural Studies of Multitargeting Inhibitors Against Mycobacterium Tuberculosis Mycolic Acid Methyltransferases
(2019-04-19)
Combating the persistent threat and low therapeutic success of treating multidrug-resistant Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, demands a worldwide effort to discover and develop new ...
Ultra-Strong, Double Network Hydrogels for Implantable Glucose Biosensors and Synthetic Cartilage
(2019-04-01)
Hydrogels, crosslinked hydrophilic polymer networks, are widely used as biomaterials because of their similarity to soft biological tissues; however, their poor mechanical properties greatly limit their utility. This work ...
A Study of a Multitude of Proppants for Fracture Conductivity of Unconventional Resources
(2019-04-12)
Onshore Oil and Gas production in the United States today primarily consists of exploiting unconventional shale reservoirs. Due to the low permeability of this type of formation, a stimulation method is required. A very ...
Experimental Evaluation of Sand, Resin-Coated Sand, and Ceramic Proppants for the Hydraulic Fracturing of Eagle Ford Shale Reservoirs
(2019-04-09)
The coupling of the technologies of the horizontal drilling and hydraulic fracturing operations has enabled the economic development of the shale oil and gas reservoirs and led to the recent significant increase in the ...
Effects of Krebs Cycle Acids and Erythritol in Clarified Egg Yolk Media on Dairy Bull Sperm Motility
(2019-04-09)
Motility rates of sperm cells affect conception rates, which affect overall dairy production rates. Cryopreservation of cells can damage the cell’s integrity and biological functions, including motility. Fresh and thawed ...
