Radial Spokes-A Snapshot Of The Motility Regulation, Assembly, And Evolution Of Cilia And Flagella, Xiaoyan Zhu, Yi Liu, Pinfen Yang Jan 2016

Radial Spokes-A Snapshot Of The Motility Regulation, Assembly, And Evolution Of Cilia And Flagella, Xiaoyan Zhu, Yi Liu, Pinfen Yang

Biological Sciences Faculty Research and Publications

Propulsive forces generated by cilia and flagella are used in events that are critical for the thriving of diverse eukaryotic organisms in their environments. Despite distinctive strokes and regulations, the majority of them adopt the 9+2 axoneme that is believed to exist in the last eukaryotic common ancestor. Only a few outliers have opted for a simpler format that forsakes the signature radial spokes and the central pair apparatus, although both are unnecessary for force generation or rhythmicity. Extensive evidence has shown that they operate as an integral system for motility control. Recent studies have made remarkable progress on the …

Far From The Madding Crowd: A Statutory Response To Crowd Crush, Tracy Hresko Pearl Jan 2016

Far From The Madding Crowd: A Statutory Response To Crowd Crush, Tracy Hresko Pearl

Faculty Articles

Crowd-related injuries and deaths occur with surprising frequency in the United States. In recent years, crowd members in the United States have sustained significant injuries and even fatalities at concerts, sporting events, “doorbuster” sales, nightclubs, and large festivals. While some of these incidents have prompted victims to file negligence suits against event organizers and venue owners, common law has proven to be ineffective at addressing “crowd crush.” Indeed, courts have repeatedly held for defendants in these cases, making a series of scientific and legal errors in the process, and providing little incentive for organizers and owners to improve their crowd …

The Role Of Fire In Montane Forest Environments In The Willamette National Forest, Oregon, Tamara G. Cox Jan 2016

The Role Of Fire In Montane Forest Environments In The Willamette National Forest, Oregon, Tamara G. Cox

All Master's Theses

High-resolution charcoal and pollen analyses were used to reconstruct a 16,000-year-long fire and vegetation history of the Blair Lake watershed in the Willamette National Forest of Oregon. The record shows that during the late glacial period, overall fire frequency was relatively low. Pinus and Abies were the dominant vegetation, along with Pseudotsuga and Alnus, suggesting that an open-canopy conifer forest developed soon after the area was glacier free. Fire frequency increased during the early Holocene. Warmer and drier conditions are reflected in the herbaceous vegetation, Artemisia, Poaceae, and Cyperaceae, suggesting that meadows or other openings were part of …

Total Value Of Phosphorus Recovery, Brooke K. Mayer, Lawrence A. Baker, Treavor H. Boyer, Pay Drechsel, Mac Gifford, Munir A. Hanjra, Prathap Parameswaran, Jared Stoltzfus, Paul Westerhoff, Bruce E. Rittmann

Civil and Environmental Engineering Faculty Research and Publications

Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside improvements in P-use efficiency. While this motivation is increasingly being recognized, little P recovery is practiced today, as recovered P generally cannot compete with the relatively low cost of mined P. Therefore, P is often captured to prevent its release into the environment without beneficial recovery and reuse. However, additional …

Toll-Like Receptor Expression And Signalling In Rat Trigeminal Neurons: Consequences For Oral Infection And Mechanisms Of Orofacial Pain., Martin Helley Jan 2016

Toll-Like Receptor Expression And Signalling In Rat Trigeminal Neurons: Consequences For Oral Infection And Mechanisms Of Orofacial Pain., Martin Helley

Peninsula Dental School Theses

The activation of Toll-like receptors (TLRs), expressed by peripheral sensory neurons, represents an innate surveillance function of sensory neurons with important consequences for neuronal function. Despite recent advances, many properties of neuronal TLRs remain poorly understood, particularly within the trigeminal system. The main objectives of this thesis, therefore, were to better characterise the expression and functional consequences of activation of neuronal TLRs in the setting of orofacial pain. A detailed, quantitative description of TLR4, TLR2 and TLR7 expression within neurochemically- identified sub-populations of trigeminal ganglion (TG) sensory neurons suggests that these receptors are primarily expressed by nociceptor sub-populations. Acute activation …

Ultrasonic Doppler Sonar Sensor System For Extraction Of Walk Signatures, Demba B. Komma Jan 2016

Ultrasonic Doppler Sonar Sensor System For Extraction Of Walk Signatures, Demba B. Komma

Honors Theses

In this work, a portable low cost sensor system is designed for the extraction of walking signatures in humans using the principle of Ultrasonic Doppler Sonar (UDS). UDS involves the use of two ultrasonic transducers acting as a transmitter-receiver pair. The transmitter produces a continuous ultrasonic signal at a specific frequency to be broadcasted onto a moving target, while the receiver will perform a frequency shift on the reflected signal in relation to the movement of the target. The sensor system used in this work is comprised of a frequency generator that drives the transducer with a 40 kHz sine …

Hospitality, Hunting, And The Home In Garden And Gun: Deconstructing Southern Identity Based On Representations Of Gender, Race, And Class, Alexa E. Willcoxon Jan 2016

Hospitality, Hunting, And The Home In Garden And Gun: Deconstructing Southern Identity Based On Representations Of Gender, Race, And Class, Alexa E. Willcoxon

Honors Theses

In my thesis, I have studied how Southern identity is formed through Southern leisure magazines, specifically Garden & Gun. I chose to narrow my focus by choosing to look only at the 2014 editions of the magazine, and I also looked primarily at the food, alcohol, homes, and hunting sections in order to be concise. Through my research, I have discovered that the magazine, although trying to be inclusive for race and gender, struggles to accurately depict the South. Instead, the magazine focuses on the primarily white, upper classes of the region, which creates and imagined reality for the reader. …

Read Me: The Emergence Of Female Voice In American Epistolary Fiction, Allison Melissa Ramsey Jan 2016

Read Me: The Emergence Of Female Voice In American Epistolary Fiction, Allison Melissa Ramsey

Honors Theses

The objective of the thesis was to study how the letter, as a narrative device provided by the epistolary genre, supplies unheard female characters with an avenue to speak when their worlds do not allow it. In the novels, the letters not only permit a female character to practice building a voice, but also provide a self-reflection and identification experience, which enables the woman to see where she is, rewrite her role, and control where she wants to go. Through reading Hannah Webster Foster's The Coquette, Alice Walker's The Color Purple, Lee Smith's Fair and Tender Ladies, and Maria Semple's …

Females Influence Brain Evolution: Dance Complexity Related To Volume Of A Sensorimotor Region In Manakins, Wilson Helmhout Jan 2016

Females Influence Brain Evolution: Dance Complexity Related To Volume Of A Sensorimotor Region In Manakins, Wilson Helmhout

Honors Theses

Manakins are a family of birds the males of which use acrobatic, non-vocal display behaviors to attract females to mate. Across the manakin family (Pipridae), species perform displays of varying complexities with variation in the number and type of display sites, acrobatics, and number of mechanical sounds. Females of at least one species, select males on the basis of 10s of ms differences in performance of certain male display elements suggesting strong sexually selection. Additionally, recent studies show a positive relationship between display complexity and relative brain weight in manakins. This overall association of complexity with brain weight could be …

Streptococcal Collagen-Like Protein 1, Scl1, Modulates Group A Streptococcus Adhesion, Biofilm Formation And Virulence, Beth Alexandra Bachert Jan 2016

Streptococcal Collagen-Like Protein 1, Scl1, Modulates Group A Streptococcus Adhesion, Biofilm Formation And Virulence, Beth Alexandra Bachert

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: The collagens comprise a large family of versatile proteins found in all three domains of life. The streptococcal collagen-like protein 1, scl1, of group A Streptococcus (GAS) binds extracellular matrix components (ECM), cellular fibronectin and laminin, via the surface-exposed globular domain. GAS strains express scl1 and form biofilm in vitro, except for M3-type strains that are particularly invasive to humans. Hypothesis: Lack of scl1 adhesin in M3 GAS results in decreased adherence and biofilm formation, and increased virulence. Results and Discussion : First crystal structure of the globular domain revealed a unique six-helical bundle fold, consisting of three pairs …

An Evaluation Of The Relationship Between Sigma-1 And Sigma-2 Receptors And The Endocannabinoid System, Jenn Miller Jan 2016

An Evaluation Of The Relationship Between Sigma-1 And Sigma-2 Receptors And The Endocannabinoid System, Jenn Miller

Honors Theses

Within the past two decades, sigma receptors have become a popular area for research. Although much has been learned about their structure, subtypes, and functions; there is still much to be learned. Consisting of two receptor subtypes (sigma-1 and sigma-2), it has been discovered that sigma receptor ligands potentiate the analgesic effects of both opiates and cannabinoids, though the exact mechanism and sigma subtype on which this occurs is still unknown. The purpose of this study is to determine if potentiation of opiates and cannabinoids occurs through sigma-1 or sigma-2 receptor signaling. Tetrad assays were performed for: 1. Morphine, an …

The Evolution Of The Vampire Other: Symbols Of Difference From Folklore To Millennial Literature, Kate Buckley Jan 2016

The Evolution Of The Vampire Other: Symbols Of Difference From Folklore To Millennial Literature, Kate Buckley

Honors Theses

With its roots in Eastern Europe and rapidly spreading to Western society in the past few hundred years, the vampire has served as a double for humanity, with the division of self between monstrosity and the human ideal. Vampires in folklore and literature have been a means by which human cultures have identified concepts of human subjectivity (identity), particularly with regard to what various societies have defined as monstrous (being Othered) within human nature. This study examines how the vampire character evolves throughout the centuries, with a specific focus on the less monstrous contemporary vampires who form hybrid communities with …
