Treatment Of Petroleum Hydrocarbons In Oil-Based Drill Cutting Mud Using Biowish Bioaugmentation Products, Diego Jose Cardenas Zepeda

Master's Theses

The efficacy of BiOWiSHTM-Thai Aqua, a commercially discontinued microbial product, in remediating oil based drill-cutting mud (DCM) was researched in this study. Experimentation was performed directly on DCM and on sand contaminated with oil extracted from DCM. A gas chromatograph-mass spectrometrer and a respirometer were used for analysis of total petroleum hydrocarbons (TPH) and CO2 production respectively. Five experiments were analyzed by TPH extraction and analysis; four experiments were analyzed by respirometric analysis. The specific microcosm conditions tested in the experiments were control, nutrient-only control, and bioaugmentation product.

This study concluded that there might be potential for bioaugmentation of TPH …

Characterization Of Two Vernier-Tuned Distributed Bragg Reflector (Vt-Dbr) Lasers Used In Swept Source Optical Coherence Tomography (Ss-Oct), Greg M. Bergdoll

Master's Theses

Insight Photonic Solutions Inc. has continued to develop their patented VT-DBR laser design; these wavelength tunable lasers promise marked image-quality and acquisition time improvements in SS-OCT applications.

To be well suited for SS-OCT, tunable lasers must be capable of producing a highly linear wavelength sweep across a tuning range well-matched to the medium being imaged; many different tunable lasers used in SS-OCT are compared to identify the optimal solution.

This work electrically and spectrally characterizes two completely new all-semiconductor VT-DBR designs to compare, as well. The Neptune VT-DBR, an O-band laser, operates around the 1310 nm range and is a …

Screening Of Biocontrol Organisms For The Management Of Phytopathogenic Fungi And Foodborne Pathogens On Produce, Antoinette Boyee De Senna

Master's Theses

The multibillion dollar agricultural industry is an important part of the United States economy, and the management of factors that affect crop and human health is imperative to maintaining this economic sector. The fungi Botrytis cinerea, Fusarium pallidoroseum, and Fusarium moniliforme are the causative agents of several plant diseases and can cause significant crop loss both before and after harvest in commodities such as strawberries, lettuce, citrus, and grains. Fungicides are employed to control these phytopathogens, but the use of these chemicals has led to an increase in fungicide resistance and may negatively affect the environment and human …

Effect Of Surfactant Architecture On Conformational Transitions Of Conjugated Polyelectrolytes, Greg A. Braggin

Master's Theses

Water soluble conjugated polyelectrolytes (CPEs), which fall under the category of conductive polymers, possess numerous advantages over other conductive materials for the fabrication of electronic devices. Namely, the processing of water soluble conjugated polyelectrolytes into thin film electronic devices is much less costly as compared to the processing of inorganic materials. Moreover, the handling of conjugated polyelectrolytes can be performed in a much more environmentally friendly manner than in the processing of other conjugated polymers because conjugated polyelectrolytes are water soluble, whereas other polymers will only dissolve in toxic organic solvents. The processing of electronic devices containing inorganic constituents such …

As the power of the Dove Real Beauty initiative appears …

Internal And External Influences On Individual Journalists, Karen Melissa Garcia

Journalism

This research paper is based on a study of the internal and external influences that affect an individual journalist and their produced work. There have been studies that research how media organizations influence the general public but there are many factors that come into play when creating the news. A journalist is influenced by their morals, beliefs and opinions or internal factors when making news decisions. Journalists are influenced by external influences as well, such as their news organization, guidelines and universal ethics.

The purpose of this study is to gain an understanding of the process that a journalist must …

Barriers To Physical Activity And Healthy Eating In Children As Perceived By Low-Income Parents: A Case Study, David W. Hey, Kristina M. Kelly, Stephanie Teaford, Ann Yelmokas Mcdermott

Kinesiology and Public Health

During the past three decades the prevalence of childhood obesity has steadily increased in the United States. Causes of childhood obesity are complex and include numerous individual and environmental factors. The purpose of this study was to determine parent perceptions on the social-ecological barriers (community, school, and family) to physical activity and healthy eating, perceived specific to their children. Self-reported data gathered from a 50-item questionnaire and six focus groups were conducted with parents (n=43) enrolled in the Women, Infants, and Children (WIC) Program. Participants (16 to 67 years old) were predominately female (88.4%), Hispanic (67%), low income, and living …

Warpage And Shape Distortion In Laser Metal Sintering, Xuan Wang

Industrial and Manufacturing Engineering

Selective Laser Sintering (SLS) is the primary method to fabricate metal and ceramic components in additive manufacturing. Due to the anisotropy of powder material, the sintering rate difference will inevitably causes shape change, distortion , and other defects of sintered parts. In this paper, a continuum model was developed to simulate the SLS process. The developed model has been successful to predict sintering kinetics. The impact of processing parameters, such as laser power, scanning speed, hatching distance, and particle size has been studied . The proposed method provides an innovative tool to optimize SLS process parameters.
