Genetic Determinants Of Habitual Physical Activity And Overweight And Obesity, Harold Lee

Master's Theses

We tested 6 single nucleotide polymorphisms (SNPs) associated with obesity from genome wide association studies for their association with physical activity (PA). Healthy European-American women (n=265) and men (n=230) (23.5±0.3yr, 24.6±0.2kg•m^-2) were genotyped for MC4R (rs17782313), FTO (rs9939609), TMEM18 (rs6548238), NEGR1 (rs2815752), SH2B1 (rs7498665), and KCTD15 (rs11084753), and completed the Paffenbarger PA Questionnaire. We examined gene interactions by summing the number of obesity effect alleles. RESULTS: Normal weight subjects with MC4R T expended 1981.2±741.7kcal∙wk^-1 less than non-carriers in total PA (p=0.008), 1825.9±650.2 kcal∙wk^-1 less in sports/recreation (p=0.027), and 1231.3±552.7 kcal∙wk^-1 less …

The Effects Of A Model Androgen 5a-Dihydrotestosterone On Mummichog (Fundulus Heteroclitus) Reproduction Under Different Salinities, Chelsea O'Connor Blatchley

Master's Theses

Abstract

Endocrine disrupting substances (EDSs) have the potential to disrupt sensitive hormone pathways, including those involved in development and reproduction. Both fresh and estuarine water bodies receive inputs of EDSs from a variety of sources, including sewage effluent, industrial effluent, and agricultural runoff. Based on limited available literature, freshwater species appear to respond to lower levels of EDSs than estuarine or marine species. To address this potential difference, a short-term reproductive bioassay was carried out under low and high salinity conditions using mummichog (Fundulus heteroclitus), a euryhaline species that is native to the east coast of North America. …

Design Of The Power Management System For Marine Sediment Microbial Fuel Cell, Ridvan Umaz

Master's Theses

Microbial fuel cells (MFC) are one of the most important renewable energy system for some underwater electronic devices and sensors; however, the MFC system does not have robustness and stability in the harsh ocean environment. One of the MFC components, the anode, must be isolated from any oxygen penetration. If oxygen enters in the anode, the electrons in the anode are consumed by it, and this compromises any voltage difference between the cathode and anode. The system then becomes impaired and ceases to function. This is inevitable in the water; therefore, using amulti-anode marine sediment MFC system is one possible …

Metamaterial Enhanced Wireless Power Transmission System, Travis Jade Heffernan

Master's Theses

Nikolai Tesla's revolutionary experiments demonstrated the possible benefits of transmitting power wirelessly as early as 1891. Applications for the military, consumers, emergency personnel, remote sensors, and others use Tesla’s discovery of wireless power. Wireless power transmission (WPT) has the potential to be a common source of consumable energy, but it will only receive serious consideration if the transmit and receive systems are extremely efficient and capable of delivering usable amounts of power. Research has been conducted to improve the efficiency and performance of nearly every aspect of WPT systems, but the relatively new field of metamaterials (MTMs) has yet to …

Evaluation Of Post-Residency Treatment Protocol Changes: A Web-Based Survey, John B. Gilbreth

Benchmarking San Luis Obispo's Municipal Energy Use: An Audit Implementation Plan, Elizabeth Laura Pfafflin

Master's Theses

As energy cost and climate change become increasingly prevalent concerns in the planning world, more and more jurisdictions are creating energy efficiency and climate action plans. As of 2011, over 120 cities and counties around the United States had already completed climate action plans (Boswell, Greve, & Seale, 2012, p. 24). A major factor in reducing energy use, and subsequently greenhouse gas emissions, is in making buildings more energy efficient. According to the EPA, buildings account for 36 percent of overall energy use in the United States (U.S. Environmental Protection Agency, 2013).

Although many of these plans set target energy …

Surgical Tooling Designed For The Direct Anterior Approach To Total Hip Arthroplasty, Jon-Peter Meckel

Master's Theses

Surgical Tooling Designed for the Direct Anterior Approach to Total Hip Arthroplasty Jon-Peter Meckel

Total hip arthroplasty (THA) is becoming more and more common in the US as people continue to live longer and more active lives. The main reason that a THA is required is due to the “wear and tear” affliction of osteoarthritis, which in the year 2000 had at least 3% of the population over 30 showing symptoms. A revitalized approach to THA is the direct anterior approach, or Smith-Petersen approach, which limits the amount of musculature affected by the surgery and creates a very stable joint …

An experimental investigation of the use low-cost microphones for unsteady total pressure measurement to detect transition from laminar to turbulent boundary layer flow has been conducted. Two small electret condenser microphones, the Knowles FG-23629 and the FG-23742, were used to measure the pressure fluctuations and considered for possible integration with an autonomous boundary layer measurement system. Procedures to determine the microphones’ maximum sound pressure levels and frequency response using an acoustic source provided by a speaker and a reference microphone. These studies showed that both microphones possess a very flat frequency response and that the max SPL of the FG-23629 …

Thermal Envelope Substitution: Energy And Cost Implications Of Using Structural Insulated Panels In The Manufactured Housing Industry, Brendan Sean Dwyer

Master's Theses

Currently 10% of all single family homes produced in the U.S. are manufactured homes with 75% of these households making less than $50,000 in annual income (Manufactured Housing Survey). Manufactured homes typically use twice as much primary energy per square foot than site built homes yet there is no agenda within the industry or its governing bodies to address this excess energy consumption. The research presented in this thesis compares the thermal envelope performance of the typical wood stud framing used in the manufactured home industry to the thermal envelope of structural insulated panels (SIPs). This comparison examines the energy …

An Analysis Of The Association Between Ependymal Integrity And Ventriculomegaly, Meredith Halling

Master's Theses

The ventricles of the brain are lined by a monolayer of ciliated ependymal cells that act as an interface between the circulating cerebrospinal fluid and the underlying tissue. Along the lateral walls of the lateral ventricles, the ependymal cells have additional significance as they are considered one of the cell types that comprise the subventricular zone (SVZ) neurogenic niche. Since lateral ventricle expansion is a well documented occurrence in not only a variety of neurological disorders but also with normal aging, it is important to consider the effect of this expansion on the ependyma. By combining MRI-based 3-D reconstructions of …

Detecting Subgroups In Children Diagnosed With Pervasive Developmental Disorder – Not Otherwise Specified, Laura A. Brennan

Master's Theses

Diagnosis of Pervasive Developmental Disorder, Not Otherwise Specified (PDD-NOS) is assigned to children who exhibit some of the social and communicative impairments common to children with Pervasive Developmental Disorders (PDD) but fail to meet the detailed criteria of other PDDs. The lack of specific criteria for the diagnosis of PDD-NOS suggests a likely degree of heterogeneity within this population, yet there is little research exploring the similarities and differences between children with PDD-NOS. The current study utilized a hierarchical cluster analysis to detect subgroups within a sample of children with PDD-NOS that provided predictive information about diagnostic outcome at age …

Talker-Specific Influences On Phonetic Boundaries And Internal Category Structure, Janice Ann Lomibao

Master's Theses

Recent findings indicate that listeners are sensitive to talker differences in phonetic properties of speech, including voice-onset-time (VOT) in word-initial stop consonants. The current work extends our earlier research by examining the degree to which listeners adjust the initial mapping from acoustic signal to segmental representation on a talker-specific basis. Two groups of listeners are exposed to a talker producing “cane.” Word-initial VOTs are manipulated such that one group hears “cane” produced with short VOTs and the other group hears “cane” produced with relatively longer VOTs. Following training, listeners’ voicing boundary for a /g/-/k/ continuum was tested. In addition, listeners …
