Growth Hormone Alters Components Related To Differentiation, Metabolism And Milk Synthesis And Secretion In Mac-T Cells, Tasha Lynn Johnson

Master's Theses

The mammary alveolar cell-T (MAC-T) cell line is able to uniformly differentiate and secrete casein proteins in response to dexamethasone, insulin and prolactin and is extensively used to study bovine mammary epithelial cell function. Growth hormone (GH) has been shown to increase milk protein synthesis both in vivo and in mammary cell models, and induce cytoskeletal rearrangement in 3T3 fibroblast cell line and a Chinese hamster ovary (CHO) cell line. Few studies have focused on identifying the mechanisms involved in differentiated MAC-T cells’ response to GH. We tested the hypothesis that MAC-T cells would respond directly to GH and that …

Benchmarked Hard Disk Drive Performance Characterization And Optimization Based On Design Of Experiments Techniques, Yu-Wei Lin

Master's Theses

This paper describes an experimental study offered by Designs of Experiments (DOE) within the defined factor domains to evaluate the factor effects of simultaneous characteristics on the benchmarked hard disk drive performance by proposing well-organized statistical models for optimizations. The numerical relations of the obtained models permit to predict the behaviors of benchmarked disk performances as functions of significant factors to optimize relevant criteria based on the needs.

The experimental data sets were validated to be in satisfying agreement with predicted values by analyzing the response surface plots, contour plots, model equations, and optimization plots. The adequacy of the model …

Influence Of Irrigation Strategies On The Photosynthetic Rate Of Syrah, Daniel Michael Rodrigues

Master's Theses

Regulated deficit irrigation (RDI) is a common and useful practice for water conservation and improving grape quality. To attain better grape characteristics and wine quality, a substantial degree of irrigation stress is intentionally allowed to occur during the first part of berry formation and can continue until later into veraison. Understanding the effects of deficit irrigation on photosynthetic rates could be helpful in determining at what degree and duration a grower should perform this irrigation practice. The focus of this study was to determine the effects of using differing degrees of RDI in a vineyard located in Paso Robles, California …

Novel Inverse Airfoil Design Utilizing Parametric Equations, Kevin A. Lane

Master's Theses

The engineering problem of airfoil design has been of great theoretical interest for almost a century and has led to hundreds of papers written and dozens of methods developed over the years. This interest stems from the practical implications of airfoil design. Airfoil selection significantly influences the application's aerodynamic performance. Tailoring an airfoil profile to its specific application can have great performance advantages. This includes considerations of the lift and drag characteristics, pitching moment, volume for fuel and structure, maximum lift coefficient, stall characteristics, as well as off-design performance.

A common way to think about airfoil design is optimization, the …

Rhode Island's Wars: Imperial Conflicts And Provincial Self-Interests In The Ocean Colony, 1739–48, Greg Rogers

Master's Theses

Whether in terms of political and military threats or economic and demographic growth, this thesis argues that Rhode Island’s involvement in this period of imperial warfare was characterized by self-interest on a variety of levels. The government’s military plans, the expansion of provincial power, attempts to raise expeditionary forces, the use of privateers, and the indirect participation of non-combatants all depict a colonial society very interested in its own local political and economic interests. Although literally “provincial,” these interests exhibit the Atlantic and global networks that the smallest of the New England colonies was situated in. These two different sets …

Management Strategies For Pitch Canker Infected Año Nuevo Stands Of Monterey Pine, Valerie A. Loe

Master's Theses

The future resilience of Pinus radiata D. Don (Monterey pine) is dependent upon the development of a silviculture program inclusive of either preventative or management techniques for the potentially fatal pitch canker disease (Fusarium circinatum Nirenberg and O’Donnell [=F.subglutinans (Wollenw. & Reinking) Nelson et al. f. sp. Pini). As an ecologically and commercially valued species, a myriad of factors threaten the genetic resources of the geographically limited natural range. This study evaluated the effectiveness of uneven-aged forest management for regeneration success in the native, pitch canker infected Año Nuevo stand at Swanton Pacific Ranch in Davenport, California. Seedling survival and …

This study presents a determination of the optimum operating parameters of a unipolar PWM inverter through theoretical and experimental analysis. The inverter is investigated in its simplest form without input DC-DC conversion or output filtering. The intent of this study is to understand the core of the inverter thoroughly before adding peripheral elements such as output filtering. Variations on the input voltage level and switching frequency were investigated to determine their impacts on the operation of the inverter and harmonics produced. Theoretical modeling and calculations confirmed by experimental measurements and analysis allow determination of the inverter operating conditions which allow …

Development Of A Novel Plasmid-Based Gene Integration System For Lactobacillus Reuteri For The Persistent Treatment Of Celiac Disease, Jeremy Keith Labarge

Master's Theses

Celiac disease (CD) is an autoimmune disorder that affects approximately 1% of the population [55]. CD is characterized by intestinal villus atrophy after consumption of gluten from wheat, barley, or rye. Patients with CD often experience abdominal pain, diarrhea, malnutrition, fatigue, and a failure to thrive. There is currently no treatment for CD. Patients must live on a strict lifelong exclusion of dietary gluten. Due to the high content of gluten in western diets and poor labeling of gluten content, adherence to a gluten free diet (GFD) is difficult [15].Nearly all the enzymes that can digest the gluten peptide are …

Differences In Aerobic Response To Wheelchair Locomotion, David Pomfret

Master's Theses

The purpose of this study was to explore the differences in the aerobic response to wheeling between wheelchair dependent individuals and able-bodied individuals of similar genders and ages. Five wheelchair dependent men (WC) and five able-bodied men (AB) performed a 13 minute wheeling test (5 min. at rest, 8 min. wheeling) at 4.0 km∙hr-1. Heart rate (HR) and VO2 were recorded using a Vmax ST system during the constant speed test. There was no significant difference in HR or VO2 between the two groups during rest. Both HR and VO2 were higher for WC during exercise. The mean METS during …

Automated Requirements Traceability: The Study Of Human Analysts, David Cuddeback

Master's Theses

The requirements traceability matrix (RTM) supports many software engineering and software verification and validation (V&V) activities such as change impact analysis, reverse engineering, reuse, and regression testing. The generation of RTMs is tedious and error-prone, though. Thus RTMs are often not generated or maintained. Automated techniques have been developed to generate candidate RTMs with some success. Automating the process can save time and potentially improve the quality of the results. When using RTMs to support the V&V of mission- or safety-critical systems, however, a human analyst is required to vet the candidate RTMs. The focus thus becomes the quality of …

An Investigation Of The Classroom Component Of Positive Behavior Intervention And Support System On Appropriately Engaged Behavior, Kathryn Marie Menousek

Master's Theses

The purpose of the present study was to evaluate the effectiveness of the withinclass component of positive behavior support in the form of ticket presentation with verbal praise in the classroom in increasing appropriately engaged behavior. A multiple baseline comparison across three classrooms was utilized to assess and compare each classroom's mean percentage of observed intervals of appropriately engaged behavior across intervention phases (baseline, direct teaching and review of PBIS classroom expectations and rules, direct teaching and review of PBIS classroom expectations and rules with ticket presentation and verbal praise, direct teaching and review of PBIS classroom expectations and rules …

The Catastrophic Position Of The Judenräte: Self-Serving Collaborators Or Honorable Martyrs?, Meghan Kerry Waldow

Master's Theses

During the Holocaust, the Nazis appointed a select group of Jewish leaders to carry out their demands and orders throughout the ghettos of Eastern Europe. These influential men made up the Judenrate. From the beginning of the ghettos until their tragic demise, these Jewish leaders were responsible for executing difficult, and at times immoral, orders from the Nazis. With little time, money, and resources, somehow these Jews were to establish a system of government within the small boundaries of their quarantine. Put in an unfathomable position, these specially chosen men received power and influence during a time that removed both …

Igniting The Creative Process: A Contemporary Approach Through Play, Personal Narrative, And Universal Themes, Jennifer Montgomery Mclees

Master's Theses

This thesis examined over the course of five years the creative process and the underlying themes informing my personal body of work in clay. I designed a frame- work for implementing similar practices in the creative process and resulting ideas of my high school art students. Developmental practices focused on the use of play, exploration of personal narrative, and introduction of universal themes and post- modern concepts, which were grounded in contemporary studio art making and art education studies. Using methods of conceptual development grounded in these three approaches to developing the creative process facilitated the development of a personal …

Influence Of Clay Mineralogy On Soil Dispersion Behavior And Water Quality, Jessique L. Ghezzi

Master's Theses

Currently, there is very little research available on nonpoint source pollution from rural watersheds. Government regulatory agencies are desperate for information regarding the causes of nonpoint source pollution, which includes the relationship between suspended soil particles and dispersion. Since soil dispersion is dependent on clay mineralogy, knowing the clay mineralogy of the soil in an area can help predict sediment loads entering the surrounding surface waters. This information is necessary to protect the resource value of our rivers, lakes, and estuaries, as well as to protect recreational activities such as fishing or hunting; but most importantly, this information is necessary …

Effects Of Reamer-Femoral Component Offset On Cement Mantle Penetration In Hip Resurfacing Arthroplasty, Mark Lloyd Paulick

Master's Theses

Hip resurfacing arthroplasty has changed the treatment of end stage arthritis without severe deformity for young, active adults. Presently, there are varying clinical approaches to implant design selection and cementation techniques. The purpose of this project is to determine what amount of reamer-femoral component offset allows for the best cement penetration into the femoral head.

Rapid prototyped femoral component models were produced with reamer femoral component offsets of 0.0 mm, 0.5 mm, and 1.0 mm. After implantation onto models of reamed femoral heads made from high-density open-cell reticulated carbon foam, cement penetration was assessed from cross-sections of the foam-implant unit. …

Hidra: Hierarchical Inter-Domain Routing Architecture, Bryan Clevenger

Master's Theses

As the Internet continues to expand, the global default-free zone (DFZ) forwarding table has begun to grow faster than hardware can economically keep pace with. Various policies are in place to mitigate this growth rate, but current projections indicate policy alone is inadequate. As such, a number of technical solutions have been proposed. This work builds on many of these proposed solutions, and furthers the debate surrounding the resolution to this problem. It discusses several design decisions necessary to any proposed solution, and based on these tradeoffs it proposes a Hierarchical Inter-Domain Routing Architecture - HIDRA, a comprehensive architecture with …

The Use Of Time-Out With And Without Escape Extinction To Reduce Escape Maintained Noncompliance, Shelly Renee Benshoof

Master's Theses

The present study evaluated the effectiveness of 2 time-out procedures for increasing escape-maintained compliance to first-time, parent-issued instructions. Children completed a screening process to determine that each participant exhibited low levels of compliance that were escape-maintained. Two nonconcurrent multiple baseline across participants designs with a crossover element between each pair were conducted to assess the effectiveness of TO and TO-EE at reducing escape-maintained noncompliance. Parents were trained to implement TO and TO-EE. TO and TO-EE were both effective at establishing and maintaining compliance levels at or above 80% when preceded by baseline and when preceded by the other time-out procedure. …

Urban Crime In Latin America: A Case Study From Medellín, Colombia, Brian Kenneth Blickenstaff

Master's Theses

Medellín, Colombia, once among the most dangerous cities in the world has seen a sharp decrease in homicides since 2002. This thesis explores the geography of violence in Medellín from 2001 through 2005 with specific emphasis on two factors thought to have contributed to the city's drop in violence: Operación Orión, a police and military response to the bloodshed, and the 2003 disarmament and demobilization of the Bloque Cacique Nutibara paramilitary organization. A series of Paired Sample T-Tests show that Operación Orión and the paramilitary demobilization seem to have contributed to falling human rights abuses and homicides, respectively. Additionally, …

Site Fidelity And Association Patterns Of Bottlenose Dolphins (Tursiops Truncatus In The Mississippi Sound, Angela D. Mackey

Master's Theses

The current study examined the site fidelity and association patterns of a community of 678 wild bottlenose dolphins (Tursiops truncatus) in the Mississippi Sound (Sound) over a three-year period (May 2004 - April 2007). Using photoidentification techniques, 74% (n = 498) of the identified dolphins were classified as transients, while 10% (n = 71) were classified as year-round residents, and 16% (n = 109) were classified as seasonal residents based on their sighting histories. Thirty-nine "select" dolphins (n = 17 seasonal residents, n = 22 yearround residents) that were sighted five or more times over the study period were used …

An Examination Of Aggressive Behavior In Indo-Pacific Bottlenose Dolphins (Tursiops Aduncus), Lauren Elizabeth Miller

Master's Theses

Agonistic behavior is often observed in animal groups in which individuals have long-term relationships. Although bottlenose dolphins (Tursiops sp.) are known to behave aggressively, relatively little is known about such behavior among wild animals. Much of the data on delphiilid aggression comes from captive studies, and is likely biased by the limited space available to the animals. In this study, video data collected from 1997 to 2007 were analyzed to examine aggressive behaviors in a wild population of Indo-Pacific bottlenose dolphins (Tursiops aduncus) off the coast ofMikura Island, Japan. The purpose of the study was to determine if age class, …

Comparison Of Extraction Techniques For Δ-9-Tetrahydrocannabinol From Urine, Ashlyn Christine Harmon

Master's Theses

With the increasing use of marijuana, efficient methods to extract and detect Δ-9-THC in urine samples and relate the concentrations found to time is a necessity so that impairment can be determined. Δ-9-THC is conjugated to glucuronic acid in urine and must be freed before the compound can be detected by chromatographic procedures. In past research, either a strong alkaline solution or β-glucuronidase has been used to cleave the bond between the Δ-9-THC and glucuronic acid before an alkaline extraction. Δ-9-THC has a pKa of 10.6 and therefore is always extracted at an alkaline pH. In this study, both a …

Does Health Anxiety Moderate The Effects Of Mortality Salience On Worldview Defense?, Toni Brooke Merkey

Master's Theses

Research generated from Terror Management Theory has demonstrated that reminding participants of their eventual death increases self-esteem striving and worldview defense (Pyszczynski, Greenberg, Solomon, Arndt, & Schimel, 2004). The hypothesis in the present study was that health anxiety would moderate this effect, based on the premise that health-anxious individuals are chronically more aware of their own mortality. To test this hypothesis, the Illness _and Attitudes Scale (IAS) was administered to 65 undergraduates to determine level of health anxiety. Participants were then randomly assigned to a mortality salience or control condition. Level of worldview defense was measured by participants' reactions to …

Variation In Social Behavior Throughout The Estrous Cycle Of A Captive Killer Whale Orcinus Orca, Kristina Marie Horback

Master's Theses

The study of cetaceans in captivity provides information on behavior, acoustics, reproduction and physiology that is often difficult to obtain with free-ranging populations. The present study examined the influence of the estrous cycle of a captive female killer whale on the rate, duration, initiation and reception of social behavior she performed with her only pool mate, a male Atlantic bottlenose dolphin. Although these two delphinid species do not commonly associate in the wild, these pool mates often engaged in affiliative tactile and social behaviors. The objectives of this project were to: (a) examine the influence of cycli~ gonadal steroid hormones …

Avoiding Confirmation Bias Through Awareness And Training, Jon Stacy Byrd

Master's Theses

In any profession where conclusions or opinions are generated by humans, there is a realization of possible error. In the profession of forensic science, errors are not taken lightly. In fact most agencies have been known to have had a no tolerance policy when it comes to errors. This means that if an analyst made a mistake in casework, he or she could be terminated. Over the past 15 years, the words "error" and "bias" have become synonymous with forensic science in the media. Major errors have surfaced in several high profile cases only to cast doubt on the forensic …

Comparison Of The Biological Attributes, First And Second Level Of Detail Of Friction Ridge Skin Of The Palms And Fingers, Kelley Bryant Counts

Master's Theses

Since the case of Daubert v. Merrell Dow Pharmaceuticals, the Daubert criteria is nothing new to forensic science. Today's practices and techniques presented in a court of law are held to high scientific scrutiny. For nearly 100 years, expert witness testimony concerning fingerprint identification has been allowed into courts with little challenge, as it is supported by several areas of research that acknowledge that no two fingerprints are the same; they will remain unchanged during an individuals lifetime, and that fingerprints have a general systematic classification system. In the past, the assumption was always made that palm prints adhered to …

A Parameterization Study Of Short Read Assembly Using The Velvet Assembler, Alex Christopher Elliot

We explore the Eulerian Path approach in detail, utilizing a de Bruijn Graph, and demonstrate current software technologies and algorithms using a sample genome. We investigate the input parameters of Velvet and discuss choice implications in the context of the E. coli putA/b1014 gene.

Classifications And Designations Of Metric Modulation In The Music Of Elliott Carter, Jason Adam Hobert

Master's Theses

Since the first use of metric modulation in 1948, this technique has become a staple in Elliott Carter's rhythmic language and compositional process, being found in most of his compositions thereafter. Though most scholars share a general understanding of metric modulation, the different processes that achieve it and its functions are not documented. This thesis will compare and contrast some definitions of metric modulation, formulate a new definition, identify four different types of metric modulation, and explore four ways in which a metric modulation may function in a composition. At the end of said thesis, the usefulness of these types …
