Defining The Genus Hydropsyche (Trichoptera:Hydropsychidae) Based On Dna And Morphological Evidence, Christy Jo Geraci, Xin Zhou, John C. Morse, Karl M. Kjer Mar 2010

Defining The Genus Hydropsyche (Trichoptera:Hydropsychidae) Based On Dna And Morphological Evidence, Christy Jo Geraci, Xin Zhou, John C. Morse, Karl M. Kjer

Publications

In this paper, we review the history of Hydropsychinae genus-level classification and nomenclature and present new molecular evidence from mitochondrial cytochrome c oxidase subunit I (COI) and nuclear large subunit ribosomal ribonucleic acid (28S) markers supporting the monophyly of the genus Hydropsyche. Both molecular and morphological characters support a broad conservative definition of Hydropsyche. Caledopsyche, Hydatomanicus, and Occutanspsyche are synonymized with Hydropsyche. The following species groups are established: Hydropsyche bronta Group (generally corresponding with Ceratopsyche and Hydropsyche morosa and newae Groups), Hydropsyche colonica Group (generally corresponding with Orthopsyche), Hydropsyche instabilis Group (generally corresponding with Hydropsyche s.s.), and Hydropsyche naumanni Group …

Forelimb Kinematics And Motor Patterns Of The Slider Turtle (Trachemys Scripta) During Swimming And Walking: Shared And Novel Strategies For Meeting Locomotor Demands Of Water And Land, Angela R.V. Rivera, Richard W. Blob Jan 2010

Forelimb Kinematics And Motor Patterns Of The Slider Turtle (Trachemys Scripta) During Swimming And Walking: Shared And Novel Strategies For Meeting Locomotor Demands Of Water And Land, Angela R.V. Rivera, Richard W. Blob

Publications

Turtles use their limbs during both aquatic and terrestrial locomotion, but water and land impose dramatically different physical requirements. How must musculoskeletal function be adjusted to produce locomotion through such physically disparate habitats? We addressed this question by quantifying forelimb kinematics and muscle activity during aquatic and terrestrial locomotion in a generalized freshwater turtle, the red-eared slider (Trachemys scripta), using digital high-speed video and electromyography (EMG). Comparisons of our forelimb data to previously collected data from the slider hindlimb allow us to test whether limb muscles with similar functional roles show qualitatively similar modulations of activity across habitats. The different …

Two Novel Approaches Used To Produce Biodiesel From Low-Cost Feedstocks, Xiaohu Fan, Xi Wang, Feng Chen Jan 2010

Two Novel Approaches Used To Produce Biodiesel From Low-Cost Feedstocks, Xiaohu Fan, Xi Wang, Feng Chen

Publications

The price of feedstock is one of the most significant factors affecting the economic viability of biodiesel manufacturer. Many approaches were investigated to reduce the biodiesel production cost. The present work gave a preliminary study of two approaches to economically produce biodiesel from waste cooking oil (WCO) and flaked cottonseed. One was the use of ultrasound-assisted synthesis of biodiesel from WCO. The other was the application of in situ transesterification from flaked cottonseed. Gas chromatography (GC) and High performance liquid chromatography (HPLC) results demonstrated the feasibility of using both approaches to produce biodiesel from low-cost feedstock.

A Comparative Identification Of Ochratoxin A In Longan Fruit Pulp By High Performance Liquid Chromatography-Fluorescence Detection And Electron Spray Ionization-Mass Spectrometry, Jing Li, Haihui Xie, Bao Yang, Xinhong Dong, Linyan Feng, Feng Chen, Yueming Jiang Jan 2010

A Comparative Identification Of Ochratoxin A In Longan Fruit Pulp By High Performance Liquid Chromatography-Fluorescence Detection And Electron Spray Ionization-Mass Spectrometry, Jing Li, Haihui Xie, Bao Yang, Xinhong Dong, Linyan Feng, Feng Chen, Yueming Jiang

Publications

Harvested longan (Dimocarpus longan Lour.) fruit are susceptible to decay caused by both bacterial and fungal infections. Ochratoxin A (OTA) is a kind of mycotoxin produced by a number of fungi. In this study, OTA was extracted from longan fruit pulp by 80% methanol and then loaded on C-18 solid-phase extraction columns. The extract solution was then analyzed by high-performance liquid chromatography - fluorescence detection (HPLC-FD) and an electron spray ionization-mass spectrometry (ESI-MS), respectively. The HPLC-FD analysis showed that a compound similar to OTA might exist in longan fruit pulp, but further analysis by the ESI-MS method demonstrated that …

Eastern Martial Arts And The Cultivation Of Persuasive Power, Kevin Cantey Jan 2010

Eastern Martial Arts And The Cultivation Of Persuasive Power, Kevin Cantey

All Theses

Martial arts, which incorporate Eastern philosophical and cultural perspectives, enhance rhetorical skill along with self-defense mastery. Furthermore, Western styled rhetorical movements within workplaces can benefit from the integration of Eastern self-cultivation approaches, specifically Taoism and Zen. Eastern martial arts training grounded in Zen and Taoist precepts, such as the interdependence of seeming opposites, the persuasive power of restraint and humility, and the benefit of applying pathos as a primary rhetorical movement, increases self-knowledge. Through dedicated practice grounded in mutual respect and an openness to challenge physical and mental limitations, the life artist emerges by simultaneously obtaining self-defense ability and virtuous …

A Survey Of The Vascular Flora Of Beaufort County, South Carolina, Daniel Payne Jan 2010

A Survey Of The Vascular Flora Of Beaufort County, South Carolina, Daniel Payne

All Theses

Beaufort County has historically been one of the most poorly botanized counties in the state. Geographically, it lies farther from the major research institutions than most other counties and has therefore received little attention from modern botanists. Major waterways, numerous private communities and an oppressive summer climate further complicate botanical research. Beaufort has one of the fastest growing human populations in the state. Natural areas are rapidly being converted into residential and commercial developments. An understanding of the county's flora is necessary to focus conservation efforts to preserve critical habitat and develop management plans for maintaining biodiversity. This project was …

Carnosine Content And Antioxidant Activity From Poultry Co-Products, Protein Meal And Stressed Poultry Tissues, Paljinder Manhiani Jan 2010

Carnosine Content And Antioxidant Activity From Poultry Co-Products, Protein Meal And Stressed Poultry Tissues, Paljinder Manhiani

All Dissertations

Four separate studies were conducted to examine carnosine levels and associated antioxidant activity in poultry co-products, in rendered poultry protein meal, in tissues from stressed or non-stressed chickens. In the first study, carnosine was extracted from poultry co-products (head, liver, lungs, tail, gizzard, brain and heart). Liver contained the highest (102.29 mg/gm) level, while brain contained the lowest level of carnosine (0.95 mg/gm). Except brain, all tissue ultrafiltrates (20.87-39.57%) and reconstituted dry powders (5.66- 14.47%) showed thiobarbituric reactive acid species (TBARS) inhibition. Head ultrafiltrate and reconstituted dry powder showed maximum while gizzard showed the minimum metal chelating activity. Free radical …

Involving Youth In Community Emergency Preparedness: Impacts Of A Multistate Initiative, Pamela Powell, Marilyn Smith, Lynette Black Dec 2009

Involving Youth In Community Emergency Preparedness: Impacts Of A Multistate Initiative, Pamela Powell, Marilyn Smith, Lynette Black

Journal of Youth Development

The National Preparedness Guidelines (2007) state, “as uniformed responders account for less than 1% of the total U.S. population, it is clear that citizens must be better prepared, trained, and practiced on how best to take care of themselves and assist others in those first crucial hours during and after a catastrophic incident.” This is increasingly more evident due to recent disasters such as hurricane Katrina. The Alert, Evacuate and Shelter (AES) program identified and trained youth/adult teams to use geospatial technology to map shelter locations and evacuation routes. Training began with team building activities to strengthen and build youth/adult …

Low-Dose Of Sodium Arsenite Causes Delayed Differentiation In C2c12 Mouse Myoblast Cells Through The Repression Of The Transcription Factor Myogenin, Amanda Steffens Dec 2009

Low-Dose Of Sodium Arsenite Causes Delayed Differentiation In C2c12 Mouse Myoblast Cells Through The Repression Of The Transcription Factor Myogenin, Amanda Steffens

All Theses

A number of epidemiological studies have correlated arsenic exposurwith cancer, skin diseases, cardiovascular diseases, and adverse developmental outcomes such as stillbirths, spontaneous abortions, neonatal mortality, low birth weight, and delays in the use of musculature. The current study used C2C12 mouse myoblast cells to examine whether low concentrations of arsenic could alter their differentiation into myotubes, which would indicate that arsenic has the ability to act as a developmental toxicant. Myoblast cells were exposed to 20nM sodium arsenite and allowed to differentiate into myotubes and expression of the muscle-specific transcription factor myogenin, along with the expression of myosin light chain …

An Examination Of The Night Hiking Experience In Parks And Protected Areas, John Beeco Dec 2009

An Examination Of The Night Hiking Experience In Parks And Protected Areas, John Beeco

All Theses

Many protected areas offer night programs for visitors; however, night hours have not been fully recognized as a potential resource in these areas. Night hours in protected areas could provide visitors with experiences unique to these times of the day. Also, typically low levels of visitation during night hours could provide visitors with additional or better suited opportunities to fulfill motivations and benefits sought during daytime activities. Furthermore, night hours could be used by managers to increase or temporally disperse use. The National Park Service's Natural Sounds and Natural Lightscapes programs provide a direction for the protection of this resource; …

Exploring Formation And Distribution Of Halonitromethanes In Drinking Waters, Jia Hu Dec 2009

Exploring Formation And Distribution Of Halonitromethanes In Drinking Waters, Jia Hu

All Dissertations

ABSTRACT
Nine halonitromethanes (HNMs) were among the more than fifty unregulated high-priority disinfection by-products (DBPs) that were monitored for and detected in drinking waters in a 2000-2002 nationwide occurrence study funded by the US Environmental Protection Agency (USEPA). The toxicology studies conducted in recent years have shown that HNMs are one of the most cytotoxic and genotoxic classes among the emerging DBPs, with orders of magnitude higher cytotoxicity and genotoxicity than any of the regulated organic DBPs. Furthermore, brominated HNMs were found to be more toxic than their chlorinated analogs, with dibromonitromethane being the most cyto- and genotoxic. Today, our …

The Effects Of Pulsed Exposures Of Suspended Clay On The Survival, Growth, And Reproduction Of Daphnia Magna, Sarah Robinson Dec 2009

The Effects Of Pulsed Exposures Of Suspended Clay On The Survival, Growth, And Reproduction Of Daphnia Magna, Sarah Robinson

All Theses

Suspended sediments are a natural component of aquatic ecosystems but anthropogenic activity such as land development can result in significant increases, especially following rain events due to surface erosion. Continuous exposures of suspended clay and silt have been shown to effect growth and reproduction of Cladocera, leading to a decrease in population growth rate. The mechanism of clay toxicity in these filter-feeding organisms is clogging of the gut tract resulting in decreased food uptake and assimilation. When placed in clean water, daphnids can purge clay from their gut and recover. In many surface waters, aquatic organisms experience episodic exposures of …

Interactive Perception For Cluttered Environments, Robert Willimon Dec 2009

Interactive Perception For Cluttered Environments, Robert Willimon

All Theses

Robotics research tends to focus upon either non-contact sensing or machine manipulation, but not both. This paper explores the benefits of combining the two by addressing the problem of extracting and classifying unknown objects within a cluttered environment, such as found in recycling and service robot applications. In the proposed approach, a pile of objects lies on a flat background, and the goal of the robot is to sift through the pile and classify each object so that it can be studied further. One object should be removed at a time with minimal disturbance to the other objects. We propose …

Deviant, Courtney Richards Dec 2009

Deviant, Courtney Richards

All Theses

ABSTRACT
I create portraits and self-portraits that explore the dualities of the western human condition, namely the deviant and the ideal, the refined and the unrefined, and the perfect and the flawed. Drawing on personal experiences with people considered outsiders or social deviants, I construct figures that embody the conflicting ideas inherent in these dualities. I explore these conflicts in drawings that are constructed with marks and shapes that are both basic and refined, and in photographs that use analytic documentation to describe social turmoil. I reference artists both contemporary and historical, such as Egon Schiele, Robert Longo, Kathe Kollwitz, …

An Animation Framework For Improving The Comprehension Of Tinyos Programs, Sravanthi Dandamudi Dec 2009

An Animation Framework For Improving The Comprehension Of Tinyos Programs, Sravanthi Dandamudi

All Theses

To meet the increasing demand for monitoring of the physical world, there has been an increase in the development of wireless sensor network applications. The TinyOS platform has emerged as a de facto standard for developing these applications. The platform offers a number of advantages, with its support for concurrency, power-efficient operation, and resource-constrained hardware chief among them. However, the benefits come at a price. Even without the TinyOS platform, the inherent parallel and distributed nature of these applications makes it difficult for developers to reason about program behavior. Further, the TinyOS programming model adopts
asynchronous, split-phase execution semantics. Developers …
