Selective Melt Recrystallization Of Acetaminophen Polymorphs Through Environmental Control, Eleanor Lowe

Honors Theses

Polymorphism is the ability for a molecule to crystallize into multiple different structures in the solid state. The preparation of one polymorph over another is practically important to pharmaceutical development, as properties of polymorphs can vary and impact the drug delivery method. Polymorph outcomes depend heavily on the environment in which the crystal is nucleated, or initially formed. Acetaminophen, the active ingredient in Tylenol, is one example of a polymorphic compound. Here we use acetaminophen as a model system to better understand primary factors controlling polymorph selection and interconversion. We hypothesize a specific atmospheric environmental factor plays large role in …

Long-Range And Chaotic Active Mixing Of Swimming Microbes In A Vortex Chain Flow, Nghia Le

Honors Theses

We present experiments studying the motion and active mixing of swimming mi- crobes in laminar, vortex-dominated fluid flows. We are testing a theory that predicts the existence of swimming invariant manifolds (SwIMs) - invisible, one-way barriers blocking the paths of self-propelled tracers in the flow in one direction. We also pro- pose that the SwIMs together can form chute structures in three-dimensional phase space that facilitate cross-vortex transport of the microbes. We also observe evidence of how these structures promote long-range transport at different non-dimensional velocities (microbe’s velocity relative to flow velocity). Long-range transport is quan- tified by measuring the …

Water And Brain Function: Effects Of Hydration Status On Neurostimulation And Neurorecording, Sam Critzer

Dissertations and Theses

Introduction: TMS and EEG are used to study normal neurophysiology, diagnose, and treat clinical neuropsychiatric conditions, but can produce variable results or fail. Both techniques depend on electrical volume conduction, and thus brain volumes. Hydration status can affect brain volumes and functions (including cognition), but effects on these techniques are unknown. We aimed to characterize the effects of hydration on TMS, EEG, and cognitive tasks. Methods: EEG and EMG were recorded during single-pulse TMS, paired-pulse TMS, and cognitive tasks from 32 human participants on dehydrated (12-hour fast/thirst) and rehydrated (1 Liter oral water ingestion in 1 hour) testing days. Hydration …

In Situ Carbon Uptake Of Marine Macrophytes Is Highly Variable Among Species, Taxa, And Morphology, Julian Jacobs, Lucian Himes, Florybeth Flores La Valle Dr.

Summer Undergraduate Research in Biology Program

Macroalgae form important coastal ecosystems and are considered to be highly

productive, yet individual macrophyte carbon uptake rates are

poorly documented and methodologies for in situ assessments of productivity

are not well developed. In this study, we employ a 13C enrichment method in

benthic chambers to calculate carbon uptake rates and assess d13C signatures of

a large stock of nearshore benthic macroalgae varying in taxa and morphology in

Southern California. Our objectives are to 1) identify the variability of carbon

uptake and inorganic carbon use among individuals of the same species or

morphology and speculate how macroalgae might respond to …

The Right To Personality: Navigating The Brave New World Of Personality-Altering Interventions, Christopher S. Sundby

Connecticut Law Review

As neuroscience progresses, policy makers will have an increasing arsenal of behavior-modifying interventions at their disposal to deploy in the hopes of reducing recidivism and making the criminal justice system more rehabilitative. While these interventions are promising, they also can pose grave risks to individual liberty interests that are insufficiently acknowledged, much less protected, by current jurisprudence. Specifically, the current legal regimes and proposed alternatives either fail to identify the nature of the liberty at stake by overly focusing on physical side effects to the exclusion of thought- and personality-altering side effects, reject completely the potential for these interventions to …

Rdkg: A Reinforcement Learning Framework For Disease Diagnosis On Knowledge Graph, Shipeng Guo, Kunpeng Liu, Pengfei Wang, Weiwei Dai, Yi Du, Yuanchun Zhou, Wenjuan Cui

Computer Science Faculty Publications and Presentations

Automatic disease diagnosis from symptoms has attracted much attention in medical practices. It can assist doctors and medical practitioners in narrowing down disease candidates, reducing testing costs, improving diagnosis efficiency, and more importantly, saving human lives. Existing research has made significant progress in diagnosing disease but was limited by the gap between interpretability and accuracy. To fill this gap, in this paper, we propose a method called Reinforced Disease Diagnosis on Knowlege Graph (RDKG). Specifically, we first construct a knowledge graph containing all information from electronic medical records. To capture informative embeddings, we propose an enhanced knowledge graph embedding method …

Investigating R(T) Functions For Spike-Timing-Dependent Plasticity In Memristive Neural Networks, Farhana Afrin, Kurtis D. Cantley

Electrical and Computer Engineering Faculty Publications and Presentations

Brain-inspired neuromorphic computation can be extremely efficient at very large scales due to inherent parallelism, scalability, and fault and failure tolerance. One widely used, biologically plausible synaptic learning mechanism is spike-timing-dependent plasticity (STDP). The proposed generic model of time-varying resistance, or R(t) elements in this work, can produce classical and beyond classical STDP in electronic spiking neural networks with memristive synapses. Hebbian and Anti-Hebbian STDP is verified with the proposed generic R(t) model by tuning the R(t) function. By appropriately placing R(t) functions with selective resistance values, symmetric or non-classical STDP learning behavior is achieved.

Hybridization And Genetic Distances Suggest One Large Monobaramin In The Gourd Family (Cucurbitales: Cucurbitaceae), Timothy R. Brophy, Jack R. Gregory, Brigitte Townsend

Faculty Publications and Presentations

The gourds form a primarily tropical and subtropical family (Cucurbitales: Cucurbitaceae) of herbaceous climbers and woody lianas composed of approximately 960 species in 95 genera and 15 tribes. Many of these are globally important food crops and ornamentals including cucumbers, gourds, squashes, melons, pumpkins, and luffas. Utilizing published literature, there is evidence of interspecific hybridization (natural, experimental cross-pollination, and embryo/ovule culture) in five of the 15 tribes. These consist of successful crosses between 131 unique species pairs, including two intergeneric and one intertribal cross, forming eight monobaramins. In addition, species that do not hybridize directly, but hybridize with the same …

Molecular And Morphological Analyses Confirm That All Loons (Aves: Gaviiformes) Form A Single Holobaramin, Timothy R. Brophy, Mary-Clark A. Matthews, Mckayla M. Guillory, Alexis M. Ramerth

Faculty Publications and Presentations

Loons or divers (Aves: Gaviiformes), a group of waterbirds found primarily in the Northern Hemisphere, are comprised of several extinct taxa as well as an extant family (Gaviidae) with one genus (Gavia) and five species. Recent phylogenetic studies suggest that the Sphenisciformes (penguins) and Procellariiformes (petrels, albatrosses, and shearwaters) form a sister group to the loons. Our previous research, based on hybridization, morphological, and vocalization data, found that all extant loons form a single holobaramin (i.e., created kind). This previous study, however, was inconclusive as to the membership of fossil taxa within the kind. The goal of the present study …

The Association Between Psychological Maltreatment And Video Game Engagement: The Role Of Distress Tolerance, Mason Lee Hatwan

Dissertations and Theses

Problematic video gaming is a growing concern worldwide, with negative consequences on mental health and social functioning. This study examines the mediating role of distress tolerance in the relationship between childhood psychological maltreatment and problematic video game engagement. Childhood psychological maltreatment is a form of abuse that can lead to long-term consequences such as emotion regulation difficulties, which have been linked to problematic gaming. Distress tolerance, the perceived ability to endure negative emotional states, may influence how individuals cope with stress and engage in regulatory behaviors like problematic gaming. Using a sample of 474 college-aged individuals (56% male, aged 18-25) …

Common Sense Or Sensibility: Vaccine Hesitancy, Parens Patriae, And The Common Good, George P. Smith Ii

Scholarly Articles

Contending with national emergencies that develop into transnational catastrophes gives rise inevitably to concerns raised by libertarians and utilitarians over the extent to which the government — state, local, and federal — can restrict or redirect personal conduct to contain, if not resolve, any existing emergency condition. Using its parens patriae powers to protect the common good — especially the communal benefits of health and safety — government must endeavor to establish health care policies, and here, mandate vaccinations to combat the COVID-19 pathogen, against the benefits that are accruing to the general public. The conclusion drawn from this Article …

The Bare Necessity Of Natural Law, Adam J. Macleod

Scholarly Articles

According to legend, someone asked literary giant Samuel Clemens, better known as Mark Twain, whether he believed in infant baptism. He replied that, not only did he believe in it, he’d seen it done. Hundreds of generations of lawyers and jurists, including many of the most influential legal scholars and judges in history, have believed in natural law for the same reason. And many still do.

Natural law and natural rights are not “nonsense on stilts,” as Jeremy Bentham famously dismissed them.1 Natural law reasoning is what lawyers and judges do every day. Today, many people tend to think of …

Is, Ought, And The Limited Competence Of Experts, Adam J. Macleod

Scholarly Articles

The moral innovators whom C. S. Lewis criticized in The Abolition of Man supposed that they could draw imperatives out of their superior understanding of sentiment and instinct. They assumed that to know what human beings want to do is to know what human beings should do. But people want to do all sorts of things that are irrational, pointless, harmful, and even downright evil. And people want inconsistent things. So the innovators are incoherent. As Lewis correctly affirmed, no amount of knowledge about nature or the world is sufficient by itself to direct us to do what is good …

Proposing A Model Antilapse Clause, Raymond C. O'Brien

Scholarly Articles

The complexity of state antilapse statutes exacerbates the task of many estate planners seeking to give prudent expression to the postmortem wishes of a client. These statutes vary as to which predeceasing beneficiaries they should apply, who should be the substitute takers to benefit instead of these lapsed beneficiaries, and how to treat beneficiaries who are treated as predeceasing because of renunciation agreements, final decrees of divorce, or, when the beneficiary kills, exploits, or abuses the one from whom the beneficiary would take. Within the modern statutory framework, there exists an abundant array of testamentary devices by which a transferor …

Gamma Attenuation And Mechanical Characteristics Of A Lead/Nbr/Sbr Rubber Composite With Black Nanocarbon Reinforcement, Elsayed Salama, Romisaa Gamal, Hassan Elshimy, Doaa E. El-Nashar, Assem Bakry, Mohamed Ehab

Basic Science Engineering

In this work, black nanocarbon-loaded 0–100 parts-per-hundred (phr) PbO-filled acrylonitrile butadiene rubber (NBR)/styrene-butadiene rubber (SBR) blend composites were prepared by using an ordinary standard rubber mixer. Both mechanical and gamma attenuation properties of the prepared samples were investigated. Maximum tensile strength and elongation at break were obtained at 40 phr PbO concentration. The obtained values for the mass attenuation coefficient with the increased PbO concentration from 0–100 phr ranged from 0.12–0.22 cm2/g at 0.239 MeV. Scanning electron microscope (SEM) with the elemental mapping analysis results showed high homogeneity at 40 phr of the prepared rubber composites, with some areas of …

Investigating Mobility Across The Life Course Through Stable Isotope Analysis At The Early Medieval Site Of Berettyóújfalu Somata, Hungary, Brianna Jayne Muir

Electronic Theses and Dissertations, 2020-2023

The Migration Period (375 to 568 CE) of Central and Eastern Europe was a tumultuous time politically, culturally, and socially. Historical and archaeological evidence provide support for the large-scale movement of multiple tribes and groups, including the Gepids and Avars, although biogeochemical evidence for mobility is currently limited for these populations. Mobility can impact individual and group health and identity, and has socio-political implications for broader regions involved. As such, identifying the extent and scale of mobility within a given population can provide nuanced insights into multiple aspects of life and society in the past. To investigate mobility in a …

Following Faculty Engaging In Collaborative Action Research To Approach Curricular Change In Undergraduate Biochemistry, Christopher Nix

Electronic Theses and Dissertations, 2020-2023

This study engaged in a curricular redesign of an undergraduate biochemistry course undertaken by a collaborative action research group. The initial portion of this study investigated student conceptual understanding of foundational concepts via a rigorously tested concept inventory. the impact of the redesign on the student foundational conceptual understanding was determined by comparison with a baseline data set. Findings suggest that students enter and exit the biochemistry course with little understanding of key foundational concepts. Examination of student performance after the incorporation of creative exercises showed a significant impact of the curricular changes on two of the concepts of interest. …

Responses Of A Pine Flatwoods Specialist Treefrog To Prescribed Fire, Ian Biazzo

Electronic Theses and Dissertations, 2020-2023

Coarse outcomes of prescribed fires are well-understood, but fine scale impacts on many assemblages are still unknown. When fire approaches, animals escape to unburned areas, hide in place, or are killed by fire. Treefrogs are unique in their use of trees for most of their adult nonbreeding activities. This reliance on uplands and three-dimensional landscape composition makes them a great model to study prescribed fire impacts. We focused analyses on an upland flatwoods specialist comprising 99% of our captures, the pinewoods treefrog Dryophytes femoralis. We assessed this species' responses to prescribed fire using two separate before-after-control-impact replicated field experiments in …

Refining The Use Of Stable Isotope Analysis In Detecting Wildlife Laundering, Kevin Guilfoyle

Electronic Theses and Dissertations, 2020-2023

The international wildlife trade has caused significant declines in wild populations. Captive breeding can reduce the pressure on wild populations caused by overcollection, but if not properly monitored, wildlife laundering can lead to further population declines. Improving the forensic ability to detect wildlife laundering will assist in monitoring the wildlife trade and enforcing regulations, thereby aiding recovery of wild populations. Stable isotope analysis has grown in importance as a forensic tool, but improvements are needed. Here, stable isotope analysis (δ13C) on eggshells of captive bred and wild sourced island apple snails (Pomacea maculata) distinguished between the two; eggshells of captive …

Variation In Genetic Structure And Dispersal Of Juvenile Green Turtles, Gustavo Stahelin

Electronic Theses and Dissertations, 2020-2023

Sea turtles are long-lived, globally distributed animals with a complex life-history. Individuals from different populations often share the same foraging areas (mixed stock aggregations). Understanding patterns of dispersal and connectivity between reproductive populations and mixed stock aggregations is fundamental for the development of effective conservation plans. Recently, green sea turtle (Chelonia mydas) populations in several reproductive areas have increased, providing an opportunity to evaluate how demographic changes in reproductive areas impact dispersal to, and the composition of, mixed stock aggregations. In this dissertation, I evaluated how dispersal from reproductive populations in the Greater Caribbean to mixed stock aggregations may have …

Comparing Hydrogen Peroxide And Sodium Perborate Ultraviolet Advanced Oxidation Processes For 1,4-Dioxane Removal From Wastewater Effluent, Tulsi Shukla

Electronic Theses and Dissertations, 2020-2023

Ultraviolet advanced oxidation processes were compared using sodium perborate (UV/NaBO3 AOP) or hydrogen peroxide (UV/H2O2 AOP) for 1,4-dioxane removal from tertiary wastewater effluent. Both UV/H2O2 and UV/NaBO3 AOPs were also tested with the addition of acetic acid. Results revealed that sodium perborate performed similarly to hydrogen peroxide – the UV/NaBO3 AOP with 6 milligrams per liter (mg/L) as H2O2 resulted in 43.9 percent 1,4-dioxane removal, while an equivalent UV/H2O2 AOP showed 42.8 percent removal. Although the oxidants performed similarly, NaBO3 is an average of 3.3 times more expensive than H2O2. However, the solid form of NaBO3 can provide a major …
