Tissue Engineering The Motoneuron To Muscle Segment Of The Stretch Reflex Arc Circuit Utilizing Micro-Fabrication, Interface Design And Defined Medium Formulation, Mainak Das
Electronic Theses and Dissertations
The stretch reflex circuit is one of the most primitive circuits of mammalian system and serves mainly to control the length of the muscle. It consists of four elements: the stretch sensor (muscle spindle/ intrafusal fiber lie parallel between extrafusal, contractile musculature), extrafusal muscle fiber, sensory neuron and motoneuron. The basic principle of the stretch reflex arc circuit is as follows: whenever there is a sudden stretch in a muscle, it needs to compensate back to its original length so as to prevent any kind of injury. It performs this compensation process using a simple negative feed back circuit called …
Diagnosing Anencephaly In Archaeology: A Comparative Analysis Of Nine Clinical Specimens From The Smithsonian Institution Nation, Stevie Mathews
Diagnosing Anencephaly In Archaeology: A Comparative Analysis Of Nine Clinical Specimens From The Smithsonian Institution Nation, Stevie Mathews
Electronic Theses and Dissertations
The inclusion of human fetal skeletons in the archaeological record can reveal much about past cultures' perception of life and death. The preservation of fetal remains in the archaeological record is a rarity, and the discovery of pathological skeletons is even rarer. A fetal skeleton from a Roman period cemetery (c. 31BC - 303AD) in the Dakhleh Oasis, Egypt, displays what are thought to be classic skeletal indicators of the neural tube defect, anencephaly. The published literature concerning the skeletal diagnosis of anencephaly is scant so in order to diagnose this individual it is pertinent to create a diagnostic standard. …
Developmental Trajectory Of Aggressive Behavior In Clinically Referred Boys: A Rasch Analysis, Scott Lafond
Developmental Trajectory Of Aggressive Behavior In Clinically Referred Boys: A Rasch Analysis, Scott Lafond
Electronic Theses and Dissertations
A majority of research investigating aggression and its development in children has relied upon the use of rating scales such as the Child Behavior Checklist (CBCL). These scales are typically developed using a conventional factor analytic approach for the selection and retention of scale items, but may not contain sufficient numbers of items to adequately assess the unidimensional construct or developmental trajectory of aggressive behavior in youths. The present study evaluates specific psychometric properties of CBCL Aggressive and Delinquency Problems clinical syndrome scale items to determine the degree to which they reflect the breadth and established developmental trajectory of aggressive …
Comparison Of The Effectiveness Of Alternative Ferrate (Vi) Synthesis Formulas As Disinfectants For Wastewater And River Water, Rachelle Ginart
Comparison Of The Effectiveness Of Alternative Ferrate (Vi) Synthesis Formulas As Disinfectants For Wastewater And River Water, Rachelle Ginart
Electronic Theses and Dissertations
Ferrate (VI) has been studied as an alternative chemical to disinfect water and wastewater in recent years. The disinfection effectiveness of two different wet oxidation ferrate (VI) synthesis formulas in wastewater and Econlockhatchee River water was evaluated. Ferrate (VI) is synthesized by addition of ferric chloride to a mixture of sodium hydroxide and calcium hypochlorite (refer to U.S. Patent 6,790,429). One ferrate (VI) synthesis formula uses below the stoichiometric requirement of hypochlorite (Low Chlorine Formula) while the other ferrate (VI) synthesis formula uses more than the stoichiometric requirement of hypochlorite (Standard Chlorine Formula). For applications requiring low chlorine residual effluent …
Delay Sensitive Routing For Real Time Traffic Over Ad-Hoc Networks, Dipika Darshana
Delay Sensitive Routing For Real Time Traffic Over Ad-Hoc Networks, Dipika Darshana
Electronic Theses and Dissertations
Wireless ad hoc network consists of inexpensive nodes that form a mobile communication network. Due to limitations of the transmission range, the nodes rely on each other to forward packets such that messages can be delivered across the network. The selection of the path along which a packet is forwarded from the source node to the destination node is done by the routing algorithm. Most commonly used routing algorithms, though effective for non-real time applications, cannot handle real-time applications that require strict delay bounds on packet delivery. In this thesis, we propose a routing protocol that ensures timely delivery of …
A Reinforcement Learning Technique For Enhancing Human Behavior Models In A Context-Based Architecture, David Aihe
A Reinforcement Learning Technique For Enhancing Human Behavior Models In A Context-Based Architecture, David Aihe
Electronic Theses and Dissertations
A reinforcement-learning technique for enhancing human behavior models in a context-based learning architecture is presented. Prior to the introduction of this technique, human models built and developed in a Context-Based reasoning framework lacked learning capabilities. As such, their performance and quality of behavior was always limited by what the subject matter expert whose knowledge is modeled was able to articulate or demonstrate. Results from experiments performed show that subject matter experts are prone to making errors and at times they lack information on situations that are inherently necessary for the human models to behave appropriately and optimally in those situations. …

Performance Based Decision System In Determining Post Closure Care (Pcc) Duration In Florida Landfills, Asawari Kulkarni
Performance Based Decision System In Determining Post Closure Care (Pcc) Duration In Florida Landfills, Asawari Kulkarni
Electronic Theses and Dissertations
This study is an evaluation of Post Closure Care (PCC) duration of landfills using performance based methodology. The post closure care phase begins once the landfill is closed. As required by the Resource Conservation Recovery Act (RCRA) Subtitle D, PCC duration for municipal solid waste landfills is 30 years. During the PCC period, the landfill operator/owner is required to conduct monitoring for leachate, landfill gas, and ground-water and maintain the integrity of the cap so that the landfill does not impose a threat to surrounding human health and environment (HH&E). The duration of PCC can be reduced by the director …
A Kinetics Study Of Selected Filtration Media For Nutrient Removal At Various Temperatures, Elizabeth Henderson
A Kinetics Study Of Selected Filtration Media For Nutrient Removal At Various Temperatures, Elizabeth Henderson
Electronic Theses and Dissertations
In recent years the nutrient levels of the Upper Floridan aquifer have been increasing (USGS, 2008). An example of this is found in Ocala, Florida where Silver Springs nitrate concentrations have risen from 0.5 mg/L in the 1960 s to approximately 1.0 mg/L in 2003 (Phelps, 2004). Because stormwater is a contributor to surficial and groundwater aquifer recharge, there is an increasing need for methods that decrease nitrogen and phosphorus levels. A laboratory column study was conducted to simulate a retention pond with saturated soil conditions. The objectives of the column studies reported in this thesis were to investigate the …
Real-Time Realistic Rendering Of Nature Scenes With Dynamic Lighting, Kevin Boulanger
Real-Time Realistic Rendering Of Nature Scenes With Dynamic Lighting, Kevin Boulanger
Electronic Theses and Dissertations
Rendering of natural scenes has interested the scientific community for a long time due to its numerous applications. The targeted goal is to create images that are similar to what a viewer can see in real life with his/her eyes. The main obstacle is complexity: nature scenes from real life contain a huge number of small details that are hard to model, take a lot of time to render and require a huge amount of memory unavailable in current computers. This complexity mainly comes from geometry and lighting. The goal of our research is to overcome this complexity and to …

The focus of this thesis is the application of data envelopment analysis to understand and evaluate the performance of diverse animal welfare organizations across the United States. The results include identification of the most efficient animal welfare organizations, at least among those that post statistics on their operations, and a discussion of various partnerships that may improve the performance of the more inefficient organizations. The Humane Society of the United States estimates that there are 4000 - 6000 independently-run animal shelters across the United States, with an estimated 6-8 million companion animals entering them each year. Unfortunately, more than half …
Without A Camera, Brian Kulbaba
Without A Camera, Brian Kulbaba
Electronic Theses and Dissertations
The method for creating my art is a matter of experimental process, manipulation of photographic elements, and time spent. I am a photographer in a digital age that does not use a camera. My moment of creativity occurs without the snap of a shutter, but relies on my understanding and control of the chemical components of photography. My work deconstructs the notion of duplication commonly found in photography. The procedure can be repeated but the results are variable. The process of creating my work often results in a multitude of prints, but the pieces that I select as art capture …
Learning African-American History In A Synthetic Learning Environment, Adams Greenwood-Ericksen
Learning African-American History In A Synthetic Learning Environment, Adams Greenwood-Ericksen
Electronic Theses and Dissertations
Synthetic Learning Environments (SLEs) represent a hybrid of simulations and games, and in addition to their pedagogical content, rely on elements of story and interactivity to drive engagement with the learning material. The present work examined the differential impact of varying levels of story and interactivity on learning. The 2x2 between subjects design tested learning and retention among 4 different groups of participants, each receiving one of the 4 possible combinations of low and high levels of story and interactivity. Objective assessments of participant performance yielded the unexpected finding that learners using the SLE performed more poorly than any other …
Structure-Function Analysis Of The Drosophila Stubble Type Ii Transmembrane Serine Protease, Rachel Morgan
Structure-Function Analysis Of The Drosophila Stubble Type Ii Transmembrane Serine Protease, Rachel Morgan
Electronic Theses and Dissertations
Hormonally-triggered regulatory hierarchies play a major role in organismal development. Disruption of a single member of such a hierarchy can lead to irregular development and disease. Therefore, knowledge of the members involved and the mechanisms controlling signaling through such pathways is of great importance in understanding how resulting developmental defects occur. Type II transmembrane serine proteases (TTSPs) make up a family of cell surface-associated proteases that play important roles in the development and homeostasis of a number of mammalian tissues. Aberrant expression of TTSPs is linked to several human disorders, including deafness, heart and respiratory disease and cancer. However, the …
Tmdl Bioassessment Sampling Of Benthic Macroinvertebrates For Lake Jesup And Lake Seminary, Gloria Eby
Tmdl Bioassessment Sampling Of Benthic Macroinvertebrates For Lake Jesup And Lake Seminary, Gloria Eby
Electronic Theses and Dissertations
The objective of this study was to obtain a bioassessment using benthic macroinvertebrates to meet TMDL (Total Maximum Daily Load) criteria for an oligotrophic (Lake Seminary) and an eutrophic (Lake Jesup) freshwater system in Seminole County, Florida. Monthly sampling of the benthic macroinverterbrate communities provided important biological data necessary to construct TMDL protocol and trophic state. Since macroinvertebrates are near the base of the food chain, they not only provide a critical role in the natural flow of energy and cycling of nutrients through the food web, but also provide a good indication of water quality by their presence and …
Cis-Regulatory Analysis Of The Pigment Cell Differentiation Gene Polyketide Synthase, David Rogers
Cis-Regulatory Analysis Of The Pigment Cell Differentiation Gene Polyketide Synthase, David Rogers
Electronic Theses and Dissertations
The analysis of Gene Regulatory Networks (GRNs) is essential to understanding the complete process of embryo development. Elucidating every gene regulatory circuit from maternal regulatory inputs all the way to the activation of differentiation gene batteries is an important step in increasing our understanding of developmental biology. In this work I study the cis-regulatory architecture of a pigment cell differentiation gene, polyketide synthase (SpPks) in the sea urchin Strongylocentrotus purpuratus. SpPks encodes an enzyme that is responsible for the biosynthesis of the sea urchin pigment echinochrome in larval pigment cells. The analysis of the promoter of a differentiation gene will …
Virtually Abstract, Michael Kappers
Virtually Abstract, Michael Kappers
Electronic Theses and Dissertations
My most recent body of work frees me from traditional animation and graphic design principles that had become second nature in my creative practice over years of commercial work in industry. I now find myself unconsciously creating shape and form without a preconceived vision of the final outcome. This allows for a free-flowing approach to my canvas. The canvas in which my forms are created is virtual space and can be described as an infinite cube. The first step I take in each of my pieces is creating a cube with the center residing at Cartesian coordinates 0,0,0. From there, …
Evaluation Of An Augmentation Of Rocky Mountain Bighorn Sheep At Badlands National Park, South Dakota, Teresa J. Zimmerman
Evaluation Of An Augmentation Of Rocky Mountain Bighorn Sheep At Badlands National Park, South Dakota, Teresa J. Zimmerman
Electronic Theses and Dissertations
Audubon’s (a.k.a. Badlands) bighorn (Ovis canadensis auduboni [Merriam 1901] now O. c. Canadensis [Shaw 1804]), described as a subspecies of bighorn sheep, was extirpated from its range by 1924. In 1964, 22 Rocky Mountain bighorn sheep were translocated from Pikes Peak, Colorado, to Badlands National Park (BNP) in southwestern South Dakota. Based on the estimated effective population size and analysis of molecular data, the bighorn sheep population at BNP underwent a population bottleneck at founding. Recommendations to restore genetic diversity in the BNP population included a mixed-sex augmentation (n > 30) from an outbred, native population of Rocky Mountain bighorn sheep. …

Research conducted as part of this study into historical and contemporary uses of the Juneberry by MHA Tribal Members indicated extensive historical use and a high interest in Juneberry reestablishment for cultural, nutritional, and economic reasons. Previous research on Juneberries has investigated factors including state of dormancy, propagation method, transplant type, and mulch type. Another purpose of this study was to elucidate the impact of presence …
Nesting And Brood-Rearing Success And Resource Selection Of Greater Sage-Grouse In Northwestern South Dakota, Nicholas W. Kaczor
Nesting And Brood-Rearing Success And Resource Selection Of Greater Sage-Grouse In Northwestern South Dakota, Nicholas W. Kaczor
Electronic Theses and Dissertations
Understanding population dynamics and resource selection is crucial in developing wildlife resource management plans, particularly for sensitive species. Greater sage-grouse (Centrocercus urophasianus) populations have declined range-wide at a rate of 2% per year from 1965 to 2003. In South Dakota, populations have generally declined. Reasons for the decline are mostly attributed to human-induced factors such as sagebrush degradation and removal, improper range management practices, oil and gas exploration, and West Nile virus infection. Sage-grouse occupy habitats at the eastern edge of their range in western South Dakota. We conducted a 2-year study to investigate the nesting and brood-rearing ecology of …
Towards A Land Conservation Ethic In Zimbabwe: An Ethical And Religio-Cultural Analysis Of Land Conservation Policies And Practices In Communal Areas, Maaraidzo Elizabeth Mutambara
Towards A Land Conservation Ethic In Zimbabwe: An Ethical And Religio-Cultural Analysis Of Land Conservation Policies And Practices In Communal Areas, Maaraidzo Elizabeth Mutambara
Electronic Theses and Dissertations
In this study I analyze the problem of land degradation in Zimbabwe's Communal Areas (CAs) from the viewpoint of the Shona of Zimbabwe with the aim to formulate a land conservation ethic that motivates people in CAs to promote ecological stability. The Shona in CAs are proximate agents as well as victims of environmental degradation. The imperative to survive in a situation characterized by drastic inequalities in the allocation of land and an exploitative global economic system, forces them to engage in unsustainable land use practices. Land conservation policies in Zimbabwe marginalize Shona values and norms, especially as they relate …

A Poetics Of The Soul: Devotional Poetry In Elizabeth Barrett Browning; Alfred, Lord Tennyson; And Christina Rossetti, Heather Cianciola
A Poetics Of The Soul: Devotional Poetry In Elizabeth Barrett Browning; Alfred, Lord Tennyson; And Christina Rossetti, Heather Cianciola
Electronic Theses and Dissertations
This study explores devotional poetry of the nineteenth century as a poetic discourse in which tropes of the human soul connect spiritual reflection with lived experience in order to engage literary, religious, and social issues in Victorian England. Like G. B. Tennyson's Victorian Devotional Poetry: The Tractarian Mode (1989), this project situates individual poets in their cultural and religious contexts, and it encourages an understanding of devotional verse as an important feature of Victorian poetry. In addition to these aims, this dissertation surveys both popular and lesser-known devotional verse by poets not formally part of the Oxford Movement in order …
