Development And Characterization Of Moisture- And Heat- Activated Oxygen Scavenging Nanoparticle, Youngjae Byun

All Dissertations

Alpha-tocopherol and a transition metal, iron, mixture was evaluated as a possible oxygen scavenger. The effects of moisture, amount of transition metal, and thermal processing on oxygen scavenging capability were also investigated. Results showed that alpha-tocopherol and transition metal had 6.72 cc oxygen per gram of oxygen scavenging capacity and 0.11 cc oxygen per gram per day of oxygen scavenging rate.
Nanoencapsulation technology was adopted for the possible oxygen scavenging activation system. Alpha-tocopherol-loaded poly caprolactone (PCL) nanoparticles were prepared by oil in water (O/W) emulsion solvent evaporation with ultrasonification. The effects of PCL concentration, solvent in oil phase, and ultrasonification …

Ecm Stabilization Strategies For Bioprosthetic Heart Valves For Improved Durability, Devanathan Raghavan

All Dissertations

Abstract
Approximately 85,000 heart valve replacement surgeries are performed every year in United States and about 300,000 surgeries worldwide. It is estimated that half of them are mechanical valve replacements and the other half bioprosthetic valve replacements. The use of bioprosthetic heart valves is slowly increasing. Bioprosthetic heart valves are made from porcine aortic valves or bovine pericardium. Commercially these bioprostheses are currently crosslinked using glutaraldehyde (GLUT) to prevent tissue degradation and reduce tissue antigenicity. GLUT crosslinks these bioprostheses by stabilizing the collagen present in the tissue via a Schiff base reaction of the aldehyde with the hydroxylysine / lysine …

Studies To Characterize The Requirements For The Binding And Release Of Erdj3, A Mammalian Er Dnaj Homolog, From Substrates, Yi Jin

Theses and Dissertations (ETD)

Heat shock protein 70s (Hsp70s) and their DnaJ co-factors exist in all organisms and in all eukaryotic organelles. These highly conserved chaperone pairs facilitate a large number of cellular processes. ERdj3 was identified as a soluble, lumenal DnaJ family member that binds to unassembled immunoglobulin heavy chains (HC) along with the BiP chaperone complex in the endoplasmic reticulum of mammalian cells. Here we demonstrate that ERdj3 binds directly to two unfolded substrates: immunoglobulin γHC and denatured firefly luciferase. Using mutagenesis studies on ERdj3 in both in vivo and in vitro binding assays, we defined ERdj3’s critical amino acids in domain …

Use Of Compliant Interbody Force Sensing Grafts To Compare Load Sharing Properties Of Unidirectional And Bidirectional Multilevel Dynamic Translational Anterior Cervical Plates, Jason Roscoe Roberson

Theses and Dissertations (ETD)

INTRODUCTION: Pseudoarthrosis is a relatively rare complication following anterior cervical arthrodesis, and is felt to be related to stress shielding. To address this, dynamic anterior cervical plates have emerged to maintain load sharing as an arthodesis matures. Dynamic plates can translate bidirectionally (allow translation in compressive and tensile loads), or unidirectionally (allow translation in compression, but maintain its position under tensile loads). The objective of this study was to compare the graft load mechanics between three plated conditions during settling using compliant interbody load cells: A static (fixed, non-moving) plate, a unidirectional multi-level translational plate design, and a bidirectional two-level …

A Kinematics-Based Testing Protocol To Study The Mechanics Of The Human Lumbar Spine, Nephi A. Zufelt

Theses and Dissertations (ETD)

The objective of this work was to develop a new kinematics-based testing protocol to quantify the axial and shear force components and rotational moment properties of the human cadaveric lumbar motion segment unit (MSU) in response to specific kinematic inputs. Modern, non-fusion spinal devices claim to treat degenerative disc disease better than traditional fusion surgery. Though there have been many biomechanical studies completed on these devices, there is still a debate over their efficacy. Conventional testing methods provide insight into the rotational properties of the MSU but lack the sensitivity or capacity to quantify lumbar MSU’s mechanical properties including shear …

Generalized Event Tree Algorithm And Software For Dam Safety Risk Analysis, Anurag Srivastava

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Event tree analysis is a most commonly used method in dam safety risk analysis modeling. Available software tools for performing event tree analyses lack the flexibility to efficiently address many important factors in dam safety risk analysis. As a result of these practical limitations, spreadsheets have been used, sometimes including Visual Basic macros, to perform these analyses. However, this approach lacks generality and can require significant effort to apply to a specific dam or to modify the event tree structure. In response to these limitations, here a generalized event tree analysis tool, DAMRAE (DAM safety Risk Analysis Engine), has been …

Development Of A Mathematical Model For 3d Reconstruction Of Target Objects By Photogrammetry, Keith F. Blonquist

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis outlines the development of a mathematical model which can be used to perform 3D reconstruction of a target object from surveillance images. 3D reconstruction is a common procedure in photogrammetry, but performing 3D reconstruction from surveillance images can be more difficult than typical photogrammetry applications.

Surveillance images are generally captured in an unsystematic manner because there is no control over the target that is being photographed. Surveillance images can have a wide variety of fields of view, are often captured with uncalibrated cameras, and typically the targets are objects for which there is no other a priori information. …

Sources And Source Processes Of Organic Nitrogen Aerosols In The Atmosphere, Mark E. Erupe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The research in this dissertation explored the sources and chemistry of organic nitrogen aerosols in the atmosphere. Two approaches were employed: field measurements and laboratory experiments. In order to characterize atmospheric aerosol, two ambient studies were conducted in Cache Valley in Northern Utah during strong winter inversions of 2004 and 2005. The economy of this region is heavily dependent on agriculture. There is also a fast growing urban population. Urban and agricultural emissions, aided by the valley geography and meteorology, led to high concentrations of fine particles that often exceeded the national ambient air quality standards. Aerosol composition was dominated …

Environmental Law, Eleventh Circuit Survey, Travis M. Trimble

Scholarly Works

The United States Court of Appeals for the Eleventh Circuit decided cases in 2008 that addressed the scope of agency discretion in several contexts. In an issue of first impression under the Clean Air Act (CAA),the court held that the Environmental Protection Agency (EPA) properly exercised its discretion in not objecting to the issuance of an operating permit to a power company that the agency had earlier formally accused of violating the CAA. In another case, the court held that the Federal Emergency Management Agency had the discretion to protect endangered species while administering the National Flood Insurance Act and …

Biological Invasions And Biocultural Diversity: Linking Ecological And Cultural Systems, Jeanine Pfeiffer, Robert Voeks

Faculty Publications

Study of the ecological and economic effects of invasive species has paralleled their progressively pervasive influence worldwide, yet their cultural impacts remain largely unexamined and therefore unrecognized. Unlike biological systems, where the ecological consequences of biological invasions are primarily negative, from an ethnoscientific standpoint, invasive species' impacts on cultural systems span a range of effects. Biological invasions affect cultural groups in myriad, often unpredictable and at times contradictory ways. This review groups case studies into a conceptual matrix suggesting three categorically different cultural impacts of invasive species. Culturally impoverishing invasive species precipitate the loss or replacement of culturally important native …

An Unconventional Design For Bus U-Turns At Signalized Intersections, Huaguo Zhou, Pei-Sung Lin, Joan Shen

Journal of Public Transportation

This paper addresses an unconventional design for accommodating bus U-turns at signalized intersections based on a case study in Miami, Florida. Field data were collected at the study site, including traffic volumes, traffic conflicts, pedestrian/ bicyclist activities, signal phase sequence, headway of buses, and radii of bus U-turns. A detailed operational analysis was performed at the signalized intersection using Synchro. The results of the operational analysis indicate that implementation of the unconventional bus U-turn design at the signalized intersection will not cause major operational problems when the total entering volume is less than 4,000 vehicles per hour. To address the …

Geography

This special section brings together 4 of the 12 studies conducted within a research program analyzing the relationships among social mobilization, governance, and rural development in contemporary Latin America. The introduction gives an overview of the contemporary significance of social movements for rural development dynamics in the region, and of the principal insights of the section papers and the broader research program of which they were a part. This significance varies as an effect of two distinct and uneven geographies: the geography of social movements themselves and the geography of the rural political economy. The effects that movements have on …

Rank-Data Distribution Method (R-D Method) For Daily Time-Series Bayesian Networks And Total Maximum Daily Load Estimation, Joon-Hee Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Daily time series-based models are required to estimate the higher frequency fluctuations of nutrient loads and concentrations. Some mechanistic mathematical models can provide daily time series outputs of nutrient concentrations but it is difficult to incorporate non-numerical data, such as management scenarios, to mechanistic mathematical models. Bayesian networks (BNs) were designed to accept and process inputs of varied types of both numerical and non-numerical inputs.

A Rank-Data distribution method (R-D method) was developed to provide large time series of daily predicted flows and Total Phosphorus (TP) loads to BNs driving daily time series estimates of T-P concentrations into Hyrum and …
