Resin And Magnetic Nanoparticle-Based Free Radical Probes For Glycan Capture, Isolation, And Structural Characterization, Kimberly Fabijanczuk, Kaylee Gaspar, Nikunj Desai, Jungeun Lee, Daniel A. Thomas, J. L. Beauchamp, Jinshan Gao

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

By combining the merits of solid supports and free radical activated glycan sequencing (FRAGS) reagents, we develop a multifunctional solid-supported free radical probe (SS-FRAGS) that enables glycan enrichment and characterization. SS-FRAGS comprises a solid support, free radical precursor, disulfide bond, pyridyl, and hydrazine moieties. Thio-activated resin and magnetic nanoparticles (MNPs) are chosen as the solid support to selectively capture free glycans via the hydrazine moiety, allowing for their enrichment and isolation. The disulfide bond acts as a temporary covalent linkage between the solid support and the captured glycan, allowing the release of glycans via the cleavage of the disulfide bond …

Rideshare Issues And Implications For Curb Management, Brandon Leonard Utterback

Landscape Architecture Masters & Design Theses - Archive

As autonomous vehicles continue to prove themselves on our roads today, a look at the considerations of implementation will be necessary. The potential for rethinking our infrastructure requirements, as a result of this new technology, could be a significant benefit to everyday life in terms of safety, congestion, and travel behavior. We must also consider the potential impact on the environment, which is often overlooked. If automobile infrastructure such as roads and parking lots are reduced in urban areas, how will this rediscovered urban space be used? How will planners, designers, and policymakers adapt our infrastructure needs when less pressure …

Microfiber Concentrations In Sand From Nesting Sea Turtle Beaches In Costa Rica, South Carolina, And Florida., Kaylin Leroy, George Boneillo

Honors Theses

Microplastics are an increasing threat to marine environments and the organisms that inhabit them. Since plastic pollution in the ocean is prominent throughout the globe, microplastic is washing ashore, affecting important sea turtle nesting sites. This study quantified microfibers in the sand of various sea turtle nesting sites around the world. Sand samples were collected in Myrtle Beach (South Carolina), Destin (Florida) and the Pacuare Reserve (Costa Rica). The microfibers were retrieved using a super saline solution and then filtered under a hood. Filters were then counted using microscopy. Microfibers were found at every sampling site, with the lowest surface …

Individual Based Modeling And Analysis Of Pathogen Levels In Poultry Chilling Process, Zachary Mccarthy, Ben Smith, Aamir Fazil, Jianhong Wu, Shawn D. Ryan, Daniel Munther

Mathematics and Statistics Faculty Publications

Pathogen control during poultry processing critically depends on more enhanced insight into contamination dynamics. In this study we build an individual based model (IBM) of the chilling process. Quantifying the relationships between typical Canadian processing specifications, water chemistry dynamics and pathogen levels both in the chiller water and on individual carcasses, the IBM is shown to provide a useful tool for risk management as it can inform risk assessment models. We apply the IBM to Campylobacter spp. contamination on broiler carcasses, illustrating how free chlorine (FC) sanitization, organic load in the water, and pre-chill carcass pathogen levels affect pathogen levels …

Major Lower Paleozoic Horizons Of The Southern Illinois Basin, John B. Hickman

Report of Investigations--KGS

The geology exposed at the surface in the southern Illinois Basin has been mapped in great detail by countless workers over the past century. With the exception of limited and scattered exposures in incised river valleys, the oldest rocks exposed outside of the Jessamine, Nashville, and Ozark Domes surrounding the Illinois Basin are Mississippian in age. Extensive deposits of Cambrian–Devonian sediments occur in the subsurface above crystalline basement in this region, however. All available data for the region were analyzed to produce a single, comprehensive set of interpretations. The data used in this study include 1:24,000-scale geologic quadrangle maps, oil …
