Lcc Mse Walls, Joel Smith

Theses and Dissertations

Lightweight cellular concrete (LCC) is mainly a mixture of water, cement, and foam bubbles. LCC generally has a cast density between 20-60 pcf and an air content between 49-84%. LCC is often used as a fill material because it has a low unit weight which reduces settlement. LCC is increasingly being considered as a backfill behind Mechanically Stabilized Earth (MSE) walls and embankments. Although engineers are using LCC in MSE walls or free face walls (MSE wall without the concrete panels or reinforcements), there is presently a lack of information regarding the performance and behavior of LCC to guide them. …

Redefining "Beneficial Use" To Combat Water Scarcity, Genene Adams

Texas A&M Law Review

Many western states in the U.S. are experiencing severe or exceptional drought, where water shortages are common, widespread, and have created troubling emergency conditions. How long these droughts plaguing the West will last is unknown. What is evident, however, is water use under a wellestablished doctrine must change in order to ensure communities do not run out of water. As a decades-long drought persists, frequent higher-than-average temperatures linger due to climate change, and population growth skyrockets, the need to implement a narrower standard for water use in the West is critical.

Solving Solar: How Past Policy Collides With Future Technology, Conner Watson

Texas A&M Law Review

This Comment discusses the importance of developing a solar waste management plan. Specifically, this Comment presents the argument that the United States should not create a large federal regulatory framework that includes expansive subsidies for solar panel recycling, but instead should invest in solar recycling technologies that offer solar recyclers the opportunity to profitably recycle junk panels. Ultimately, the federal government’s role should be limited to one of investment and support as states craft solar waste management systems that work for them.

In support of this argument, this Comment explores the history and future of solar panel development, the current …

Chronic Kidney Disease Android Application, Paul Le

Computer Science and Engineering Senior Theses

Chronic kidney disease is increasingly recognized as a leading public health problem over the world that affects more than 10 percent of the population worldwide, where electrolytes and wastes can build up in your system. Kidney failure might not be noticeable until more advanced stages where it may then become fatal if not for artificial filtering or a transplant. As a result, it is important to detect kidney disease early on to prevent it from progressing to kidney failure. The current main test of the disease is a blood test that measures the levels of a waste product called creatine …

Computational Fluid Dynamics Modeling Of Internal Wave Interactions On Conch Reef, Florida Keys, Megan Miller

All HCAS Student Capstones, Theses, and Dissertations

Internal waves breaking on continental shelves play a significant role in mixing and nutrient delivery to coral reef ecosystems. As internal solitary waves, or solitons, propagate shoreward onto continental slopes, they can become unstable and break into turbulent bores that bring cool, nutrient-rich sub-thermocline water shoreward onto coral reefs. The propagation of turbulent bores generated by internal waves interacting with a complex surface creates high-frequency variabilities in the thermal and nutrient environment of Conch Reef in the Florida Keys, which has been studied previously. Here, I have created a three-dimensional model using ANSYS Fluent Computational Fluid Dynamics (CFD) software to …

The incursion of water hyacinth, Pontederia crassipes in Lake Okeechobee has resulted in management systems to be implemented to reduce the coverage of the invasive macrophyte. Its residence in the Lake Okeechobee ecosystem and the effects it has on organisms in the lake, whether it be positive or harmful is unknown. This study attempted to assess the potential effects that water hyacinth has on aquatic biota in Lake Okeechobee. Biotic data were collected on open water, water hyacinth covered, and native vegetation covered habitats via hook-and-line fishing, electrofishing, baited minnow traps, and the sampling of plant roots over a thirteen-month …

Functional Role Of Toll-Like Receptor Associated Micrornas In Intervertebral Disc Pathophysiology, Petra Cazzanelli

Theses

Intervertebral disc (IVD) degeneration is one of the main contributing factors to low back pain (LBP), the leading cause of years lived in disability worldwide. The degenerative processes in the IVD tissue are characterized by the metabolic dysregulation of IVD cells and aberrant mechanical loading. The major hallmarks of this multifactorial pathology are the degradation of the extracellular matrix (ECM), inflammation, and cell loss. Inflammation has been specifically linked to the development of discogenic LBP, as increased secretion of pro-inflammatory cytokines can cause the infiltration of immune cells and nerve fibers. Toll-like receptors (TLR) are key regulators of inflammation, amongst …

Flexible Multifunctional Titania Nanotube Array Platform For Biological Interfacing, Hoda Amani Hamedani, Thomas Stegall, Yi Yang, Haochen Wang, Ashwin Menon, Anubhuti Bhalotia, Efstathios Karathanasis, Jeffrey R. Capadona, Allison E. Hess-Dunning

Faculty Scholarship

The current work presents a novel flexible multifunctional platform for biological interface applications. The use of titania nanotube arrays (TNAs) as a multifunctional material is explored for soft-tissue interface applications. In vitro biocompatibility of TNAs to brain-derived cells was first examined by culturing microglia cells—the resident immune cells of the central nervous system on the surface of TNAs. The release profile of an anti-inflammatory drug, dexamethasone from TNAs-on-polyimide substrates, was then evaluated under different bending modes. Flexible TNAs-on-polyimide sustained a linear release of anti-inflammatory dexamethasone up to ~11 days under different bending conditions. Finally, microfabrication processes for patterning and transferring …

Evaluation Of Unmanned Aerial Vehicle Flight Parameters That Impact Stockpile Volume Computations, Nicole Marie Hastings

Theses and Dissertations

Stockpile volumes are monitored by their companies as the product (i.e., aggregate, soil) is moved in and out of the facilities to ensure minimal product loss. Companies are mandated to report product movement to the government to ensure that the aggregate and soil is going where it is supposed to go. Many tools are used to monitor stockpile volumes including truck scales (to weigh incoming and outgoing trucks), light detection and ranging (LiDAR), Global Navigation Satellite System (GNSS) equipment, and unmanned aerial vehicle (UAV) photogrammetry. These processes give a good estimate of stockpile volumes. Errors in these estimates typically come …

A Tunable System For High Frequency Bioimpedance Plethysmography, Daniel H. Tebbs

Theses and Dissertations

Bioimpedance measurements are useful for determining a variety of biological conditions. By accounting for small impedance variations due to the arterial pulse, the effect of the blood can be studied more closely. The quasi-circulator system presented enables monitoring of pulsatile impedance changes with input frequencies above 1 MHz. The adjustable Rmatch allows for dynamic tuning of the system to increase sensitivity. By tuning Rmatch to be near the match point, the pulsatile signal in the output magnitude can be amplified, and tuning Rmatch to be at the match point causes the pulsatile signal in the output phase to be amplified. …

Simulating Incident Management Team Response And Performance, Daniel Jarvis

Theses and Dissertations

The effectiveness of Incident Management Teams (IMT) in reducing the duration and impact of traffic incidents is well-documented. The capacity of large-scale simulation models to illustrate the negative effects of these incidents on vehicle delays and excess user costs (EUC) is also widely recognized. However, there is a gap in research integrating large-scale simulation modeling with IMT performance analysis. This study uses the Multi-Agent Transport Simulation (MATSim) framework to simulate the impact of incidents and evaluate the performance of IMT across the regional network of Utah's Wasatch Front, analyzing their operation in various hypothetical situations. Our findings validate the role …

Low-Cement Concrete Mixture For Bridge Decks And Rails, Soumitra Das, George Morcous Ph.D., Jiong Hu

Nebraska Department of Transportation: Research Reports

Right after construction, drying shrinkage of restrained concrete bridge decks and rails causes early-age cracking, insertion of water and chemicals, and corrosion of reinforcing steel that eventually leads to delamination and spalling of concrete. The main objective of this research is to control early-age shrinkage cracking by reducing cementitious material content in bridge deck and rail concrete mixtures. Several reduced cementitious materials concrete (RCMC) mixtures were developed by optimizing aggregate particle packing and conducting overall performance evaluation. This evaluation was carried out in three phases. The first phase investigated the feasibility of new RCMC mixtures by testing workability, compressive strength, …

Towards Bias-Resilient Deep Neural Networks, Robik Shrestha

Theses

Deep learning systems have brought about a paradigm shift in the field of artificial intelligence, often surpassing human performance across a wide range of tasks. Nonetheless, there are numerous apprehensions regarding their robustness when deployed in the real world. Multiple studies have demonstrated that deep learning models tend to latch onto biases present in their training data instead of truly solving the tasks. Given the pervasive nature of this issue across various datasets and tasks, researchers have proposed a variety of techniques to improve bias resilience. However, the evaluation protocols used in prior works leave many open questions regarding their …

Stress-Related Biosocial Mechanisms Of Discrimination And African American Health Inequities, Bridget J. Goosby, Jacob E. Cheadle, Colter Mitchell

Department of Sociology: Faculty Publications

This review describes stress-related biological mechanisms linking interpersonal racism to life course health trajectories among African Americans. Interpersonal racism, a form of social exclusion enacted via discrimination, remains a salient issue in the lives of African Americans, and it triggers a cascade of biological processes originating as perceived social exclusion and registering as social pain. Exposure to discrimination increases sympathetic nervous system activation and upregulates the HPA axis, increasing physiological wear and tear and elevating the risks of cardiometabolic conditions. Consequently, discrimination is associated with morbidities including low birth weight, hypertension, abdominal obesity, and cardiovascular disease. Biological measures can provide …
