Measuring Viability Of The Red-Tide Dinoflagellate Lingulodinium Polyedra Following Treatment With Ultraviolet (Uv) Light, Scott Riley

HCNSO Student Theses and Dissertations

Harmful algae blooms (HABs) have caused millions dollars in annual losses to the aquaculture industry, inhibited beach recreation, and have threatened marine and human health. HABs and red tides can develop suddenly and their frequency, geographic range, and intensity have increased over the past decade. A possible source for spreading and seeding new areas expanding the geographic range of HABs is ballast water. The process of ballast water discharge has been identified as a primary vector for the translocation of non-indigenous species (NIS) and invasive species. National and international efforts are currently underway to address the impact of NIS and …

Inhibition Of Angiotensin-Converting Enzyme-2 (Ace-2) Activity And Radioligand Binding Of A Putative Ace-2 Inhibitor, Andrea Linares Apr 2014

Inhibition Of Angiotensin-Converting Enzyme-2 (Ace-2) Activity And Radioligand Binding Of A Putative Ace-2 Inhibitor, Andrea Linares

Undergraduate Student Symposium

The objective this study was to test the efficacy of a novel angiotensin-converting enzyme-2 (ACE-2) inhibitor JFS101. A potent inhibitor of ACE-2 (MLN-4760) was developed, but then abandoned when it became clear that ACE-2 metabolizes angiotensin II (Ang II) to form Ang 1-7. We developed a radioiodinizable analog of MLN-4760 (JFS101) that would more closely mimic Ang II. Both the uniodinated and monoradioiodinated as well as the S,S versus the S,R analogs were tested for their ability to inhibit ACE-2 metabolism of an artificial ACE-2 substrate (MCA-APK[Dnp]) using recombinant human ACE-2 (rhACE-2) and for their ability to bind to ACE-2 …

Philosophically Speaking, Capital Punishment Is Not The Answer, Nathaniel J. Dolan Apr 2014

Philosophically Speaking, Capital Punishment Is Not The Answer, Nathaniel J. Dolan

Undergraduate Student Symposium

Like all species of animal creature on our planet, humans – each and every one – are entirely capable of committing the most heinous acts imaginable. What draws the distinction for the criminal elements among us is merely a missing level of restraint in the face of conflict, duress, pressure, disappointment, perceived threats, and our own immutable passions. When responding to criminal acts through a system of jurisprudence we are each forced to confront the morass of distinct philosophies underscoring the particular issues. The American system of justice is fundamentally flawed in that it simply cannot determine the most effective …

Symbolist Movement Of Modern Theatre, Angelica Zadak Apr 2014

Symbolist Movement Of Modern Theatre, Angelica Zadak

Undergraduate Student Symposium

A quote by the French symbolist playwright Paul Claudel claims, “All that passes is raised to the dignity of expression; all that happens is raised to the dignity of meaning. Everything is either symbol or parable.” The development of the symbolist movement of modern theatre from 1874 to 1915 gained clout through those who shared in Claudel’s observation. Throughout the paper, the symbolist movement of modern theatre will be explored along with those who struggled to make the movement come to life on the stage. The struggle between realists and symbolists concerning what is real and what is incredulous fantasy …

A Case Report Of Improving Running Biomechanics Through Movement Pattern Training In A Female Competitive Runner, Anya Ellerbroek, Stephanie Hauck Apr 2014

A Case Report Of Improving Running Biomechanics Through Movement Pattern Training In A Female Competitive Runner, Anya Ellerbroek, Stephanie Hauck

Undergraduate Student Symposium

Running-related musculoskeletal injuries occur with an overall yearly incidence rate between 37 and 65%. Most are lower extremity with 50-75% of all running injuries classified as overuse. These injuries have been linked to faulty running biomechanics such as foot over pronation, and excessive hip adduction and internal rotation. Therapists have primarily focused on strengthening the hip muscles to prevent excessive motion. However, little evidence supports the efficacy. This case outlines the use of functional movement pattern training rather than isolated muscle training to improve faulty biomechanics. The participant was a 19 year old female competitive distance runner with a history …

A Survey Of The Cost-Benefit Analyses Of Uninsurance, Prasanna Marathe Apr 2014

A Survey Of The Cost-Benefit Analyses Of Uninsurance, Prasanna Marathe

Undergraduate Student Symposium

Health care spending is carving up an increasing share of the US national gross domestic productapproximately 18%- but the absolute number-46 million- and the proportion of uninsured Americans15%- are also on the rise (McConnell, Microeconomics: Principles, Problems, and Policies, 2012). These counterintuitive trends are alarming and cannot be sustained without significant net economic costs. A survey of the cost-benefit analyses of uninsurance reveals that uninsurance has tremendous opportunity costs (ex: foregone economic productivity and higher mortality) and is economically (net) harmful. It also reveals that extending insurance to currently uninsured will be economically (net) beneficial to our nation as a …

A Web Interface For Visual Galaxy Classification, Chau Phung Apr 2014

A Web Interface For Visual Galaxy Classification, Chau Phung

Undergraduate Student Symposium

Galaxies can have a variety of shapes. These morphologies range from disk-dominated to elliptical and irregular appearances. Understanding galaxy morphology is crucial in order to address questions concerning the evolution and formation of galaxies and their dark matter content. However, determining galaxy morphology is a difficult task. While galaxies can be classified using automatic algorithms, the human classification by eye is more sensitive to fine structures such as spiral arms and galaxy interaction features. Unfortunately, galaxy catalogs are very big, making it a time consuming process to classify thousands of galaxies. In order to expedite this process, we developed a …

Creepy Is Quickest But Sexy Is Next: Evolved Psychological Mechanisms Impact Stimuli Processing Speed, Katherine H. Cadwalader Apr 2014

Creepy Is Quickest But Sexy Is Next: Evolved Psychological Mechanisms Impact Stimuli Processing Speed, Katherine H. Cadwalader

Undergraduate Student Symposium

Evolutionary psychological theory posits that humans have evolved psychological mechanisms (EPMs) that function to aid in survival and reproduction by processing stimuli perceived to be associated with specific problems of survival and reproduction. One such problem is that of identifying and securing a high quality mate. Consequently, people have EPMs devoted to processing information relevant to identifying high quality individuals who may be either potential mates or potential competitors against whom they may have to fight for access to mates. During mate value evaluation, however, it is possible that one mechanism may have to simultaneously process conflicting information. For example, …

Enculturation Through Ambiguity: Morality And Meaning In Children's Tv Shows, Khadija Chowdhury Apr 2014

Enculturation Through Ambiguity: Morality And Meaning In Children's Tv Shows, Khadija Chowdhury

Undergraduate Student Symposium

It is easy to blame excessive “screen time” for the educational and behavioral difficulties that children face. And with children under the age of 6 watching an average of 2 hours of screen media a day, and older children averaging 4 hours a day, such practices deserve our attention. Children’s television shows in particular often get criticized for their thin content, gross humor, and “passive” viewing. But television shows do teach values and social conventions. And such enculturation need not be looked at as passive. As Haas and Flower write, “‘meaning’ does not exist in a text but in readers …

Mechanism Of Apoptosis Induced By Phycocyanin In Lncap And A549 Cancer Cells, Haley Nation, Omar Garcia, Omar Viqar Apr 2014

Mechanism Of Apoptosis Induced By Phycocyanin In Lncap And A549 Cancer Cells, Haley Nation, Omar Garcia, Omar Viqar

Undergraduate Student Symposium

Phycocyanin is a pigmented protein found in cyanobacteria produced by aphanizomenon flos-aquae (a freshwater species of blue-green algae) and spirulina. Phycocyanin (PC) has been researched extensively in the last twenty years because of its anti-cancer properties. Despite numerous critical findings, the anti-cancer mechanism for how PC induces apoptosis in cancer cells is still unknown.

The purpose of our experiment was to determine the uptake of PC by cancer cells and then study different mechanisms of apoptosis. PC naturally emits red florescence, which was utilized to verify the uptake by LNCaP prostate cancer cells. We were able to determine that …

Neurogenesis In Octopus Vulgaris, Jelileh Whitmore Apr 2014

Neurogenesis In Octopus Vulgaris, Jelileh Whitmore

Undergraduate Student Symposium

Cephalopods, particularly the octopus, have the largest and most complex invertebrate brains and show markers of behavioral complexity. Several mammalian studies have demonstrated a correlation between learning and neurogenesis (the birth of new neurons) in the hippocampus of the adult brain. The vertical lobe of Octopus vulgaris is thought to be analogous to the hippocampus of mammalian brain; however, neurogenesis has never been reported in the octopus. We used thymidine incorporation assays and immunostaining to demonstrate neurogenesis in the developed octopus brain. We are currently examining the proliferation, differentiation, integration, and cell death of newly born neurons in the octopus …

Next Generation Event Scheduling System, Jeremy Cantor Apr 2014

Next Generation Event Scheduling System, Jeremy Cantor

Undergraduate Student Symposium

Current event scheduling systems are often inefficient. Traditional business practices, such as employing office assistance to manually record event times requires the customer to languish needlessly on the telephone while waiting receive assistance and to repeat that process several times to establish just one appointment or a meeting. New software scheduling tools significantly reduces errors, yet they are still modeled after traditional processes. We have proposed to model scheduling as a “protocol” and use a visualization approach to depict the process. Using this protocol approach, the project includes analysis of the traditional scheduling processes. We have identified the inefficiencies that …
