Can Prescribed Fire Reduce Tick Parasitism Of Birds?, Leslie A. Sterling, Kim Medley, Katie Westby, Solný Adalsteinsson
Undergraduate Research Symposium Posters
Tick-borne diseases spread through enzootic transmission cycles that often involve ticks parasitizing bird hosts. Some avian species are competent reservoirs, amplifying the pathogens that cause tick-borne illnesses in humans. Prescribed burns in forests have the potential to reduce tick-borne disease risk if they limit interactions between ticks and infectious wildlife hosts. Although prescribed burns are increasingly being used for a variety of habitat management purposes, little is known about how they affect tick-host interactions. We hypothesize that if prescribed fires reduce tick abundance, then birds in burned forest plots will host fewer ticks than birds in unburned forest plots. Experimental …

Enteric pathogens employ numerous strategies to breach the intestinal epithelial barrier. One critical target of these pathogens is the host cell cytoskeleton. Pathogens may induce cytoskeletal remodeling to disrupt tight junctions and increase the permeability of the epithelium to gain access to underlying tissue. Alternatively, the cytoskeletal machinery may be directly co-opted to facilitate the attachment, invasion, or intracellular motility of these pathogens. The vasodilator-stimulated phosphoprotein (VASP) is a processive actin polymerase that induces membrane remodeling through the polymerization of actin cytoskeletal filaments. Interestingly, VASP is regulated by a variety of pathogens to induce cytoskeletal remodeling in host cells. If …

Mental Health & The Modern Educator, Samantha Nousak
Honors Projects
Mental health issues are far more prevalent than most are aware; according to the National Institute of Mental Health (2017), 49.5% of 13 to 18-year-olds will qualify for any mental illness. Mental health concerns will impact students in every single classroom, yet curriculum for Education majors does not include more than rudimentary information on this topic. This presentation aims to provide basic facts pertaining to mental health (including incidence rates, educators' responsibilities, and the impact mental health issues can have on students), discuss broad strategies to employ with students with mental health concerns (basic do's and do not's), and provide …

The Earth's Magnetosphere, Soren Ormseth
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The Interstellar Boundary Explorer (IBEX) is an Earth orbiting satellite launched in 2008; designed to map the boundary of our Solar System. In this presentation, we focus on how data collected by the IBEX-Hi sensor can be used to map the distribution of hot ions within the Earth's magnetosphere. As opposed to other satellites, IBEX images the magnetosphere from afar rather than by going through it. An improvement on the previous imaging techniques was developed, and we compare the new results to the old.
The Effects Of Chitosan On Resveratrol-Loaded Zein Nanoparticles, Brian Sohn
The Effects Of Chitosan On Resveratrol-Loaded Zein Nanoparticles, Brian Sohn
Undergraduate Research Symposium Posters
Resveratrol is a naturally occurring polyphenolic compound showing health benefits, including anti-carcinogenic, anti-microbial, anti-HIV/AIDS, neuro-protective, and cardio-protective activities. It has been proposed as a promising dietary supplement or functional ingredient in foods to lower the prevalence of many chronic diseases. However, due to the molecule’s chemical instability, low bioavailability, and poor water solubility, its application was vastly limited. Therefore, extensive research has been conducted regarding microencapsulation of resveratrol. In this study, resveratrol was double encapsulated with zein, a prolamine protein found in maize, and chitosan, a hydrophilic, linear polysaccharide derived from chitin via a deacetylation reaction. Due to their biocompatible, …
Electrochemical And Spectroscopic Study Of Peptide-Template Melanins, Daniel Courter, Olivia Rossi, Zhen Tian
Electrochemical And Spectroscopic Study Of Peptide-Template Melanins, Daniel Courter, Olivia Rossi, Zhen Tian
Honors Theses and Capstones
Melanins are organic polymers made up of 5,6-dihydroxyindole carboxylic acid (DHICA) and 5,6-dihydroxyindole (DHI). Biochemical systems synthesize melanins through a complex reaction pathway. Previous research exhibited that naturally-occurring melanins (NatMel) and their synthetic analogues (SynMel) can potentially serve as electrode materials for aqueous charge storage devices. Small surface area creates technical challenges for these melanins as charge storage materials. This research herein demonstrates that the structure of melanins can affect the charge storage capacities of monovalent Na+cations and divalent Mg2+ cations. 2-D sheet-like peptide melanins (PepMel) were synthesized into tripeptides consisting of aspartic acid (D), phenylalanine (F), …

According to the American Art Therapy Association, art therapy is "a mental health profession in which clients, facilitated by the art therapist, use art media, the creative process, and the resulting artwork to explore their feelings, reconcile emotional conflicts, foster self-awareness, manage behavior and addictions, develop social skills, improve reality orientation, reduce anxiety, and increase self-esteem.” While creating art on your own at home is not the exact same as official art therapy, it has been shown that this form of art can help to decrease stress levels. For my Honors Capstone Project I have reviewed the research and studies …
