Preserving Wildlife In San Luis Obispo City By Way Of San Luis Obispo Creek, Sydni Nicolici

Liberal Arts and Engineering Studies

The effectiveness of San Luis Obispo wildlife easements and city open space utilized to preserve species of concern is correlated to the health and maintenance of the San Luis Obispo Creek. I propose that the health of the Creek be addressed before more open space is added to the green belt surrounding the city. This bottom-up approach to preservation will ensure all steps of habitat will function as they should.

Mid-Twentieth Century Residential Development In San Luis Obispo, Allison Dean Zike

Master's Theses

San Luis Obispo’s mid-century spanned the years beginning in the Great Depression and ending during the post-World War II housing boom. During this time the City grew in population and in size, adding several acres of land and thousands of single-family residential parcels. This research presents a chronological representation of the City’s growth, as well as key events in the City’s history. Residential development in the mid-century brought several new styles of architecture to the City including Mid-century Modern and Prairie homes among others. These architectural styles are detailed and presented in order to identify and guide the preservation of …

Growing Gardens: Botanical Gardens, Public Space And Conservation, Terra Celeste Colburn

Master's Theses

This thesis examines the history of botanical gardens and their evolution

from ancient spaces to the modern gardens of the 20th century. I provide a brief

overview of botanical gardens, with a focus on the unique intersection of public

participation and scientific study that started to occur within garden spaces during

the 20th century, which still continues today. I reveal the history of gardens that

influenced the uses of gardens today, with a focus on: the first ancient gardens

and the dependency societies had on them, the influence of science in gardens

starting in the Enlightenment period, the shift away …

Assessment Of Site And Soil Characteristics Of Rill Erosion Following The Lockheed Fire In The Little Creek Watershed, Swanton Pacific Ranch, Lynette Kristine Niebrugge

Master's Theses

The Lockheed Fire occurred in August 2009, burning 7,819 acres of the coastal mountains north of Santa Cruz, California. The fire burned a large portion of the Scotts Creek watershed, including over 90 % of the Little Creek watershed, much of which is on Cal Poly’s Swanton Pacific Ranch (SPR). After intense winter rains in 2010 there was a significant amount of hillslope-derived sediment deposited on the roads and in the creek. A large portion of this material was derived from two chaparral hillslopes. These hillslopes were identified as the only two hillslopes within the Little Creek subwatershed where an …

Application Of A Heuristic Method To A Water Distribution System For Determining Optimal Water Quality Monitoring Locations, Lawrence David Johnson

Master's Theses

Although regulations and requirements for water quality source monitoring have increased, drinking water distribution systems can still be considered vulnerable to purposeful or accidental contamination.

This study analyzes the transport of the hypothetical contaminant Cryptosporidium through the distribution system of a city with a population of 30,000 to 50,000 in an attempt to locate the optimal monitoring locations in the distribution system. Cryptosporidium was selected due to its resistance to chlorine and it’s conservative properties for vulnerability assessments. The method for selecting the optimal monitoring locations was taken from Chastain (2004) which developed and examined the method for a virtual …

A New Computational Model To Augment The Design Of Microfluidic Separations: Electric Field Assisted, Hydrodynamic Chromatography, Jeffrey D. Wells

Master's Theses

This project encompasses the implementation of a computational model to simulate the microfluidic separation of like-charged particles in a continuous flow environment. By accomplishing this task the model can be used to optimize future fractionations by tailoring the process parameters to the properties of the target particles. The primary goal of this project is to develop a vectorized code within Matlab® that captures a sufficient quantity of the physics in separations to assist with the optimization and design of microfluidic systems.

This project differs from other computational models in that it utilizes a personal computer to run the simulation in …

Cascaded High Voltage Converter With Variable Control For Pulsed Electric Field Applications, Emmanuel Loza

Master's Theses

Living a sustainable lifestyle while facing increasing population and decreasing natural resources has become one of humanity’s largest challenges. Locating fossil fuels is becoming more difficult while the demand for them to power our societies is ever increasing. Instead of finding more efficient methods of extracting fossil fuels, developing technologies that create renewable substitutes for fossil fuels is now the strategy. Algae biofuel matches fossil fuel performance while also meeting the criteria for renewable energy. The focus now shifts to finding methods for commercially producing algae biofuel. Therefore, the objective of this thesis is to develop a system that provides …

Feasibility Study Into The Use Of 3d Printed Materials In Cubesat Flight Missions, Daniel Fluitt

Master's Theses

The CubeSat Program has provided access to space for many universities, private companies, and government institutions primarily due to the low cost of CubeSat satellite development. While these costs are orders of magnitude lower than similarly capable nano-satellite missions, they are still outside of the budgetary constraints of many potential developers including university and high school clubs. Using 3D printed plastics in the production of CubeSat structures and mechanisms presents a large cost savings opportunity that will allow these institutions to participate in the development of these satellites, expanding the educational and scientific impact of the CubeSat Program.

The Characterization Of Biofilm Attachment To Metal Interfaces: Effects Of Substratum Properties, Marcel D. Mendes

Master's Theses

Bacteria are among the most abundant microorganisms on earth, and can be found in essentially every environment. When a clean surface is exposed to media containing planktonic bacteria, the bacterial cells will attach to the surface and aggregate to form what is known as a biofilm. Biofilms have been shown to negatively affect many industries including medical, industrial, and food science applications. While biofilms have been well characterized from a microbiology perspective, there has been much less research from a materials science standpoint. It is hypothesized that the material properties of the substratum (such as the micro-structure) have a significant …

Preparation And Characterization Of Electrospun Poly(D, L-Lactide-Co-Glycolide) Scaffolds For Vascular Tissue Engineering And The Advancement Of An In Vitro Blood Brain Barrier Model, Deven Chandrakant Patel

Master's Theses

Developing an in vitro Blood Brain Barrier model that will replicate the physiological, anatomical, and functional characteristics of the native BBB has gained significant attention. Such a model would enable prediction of the penetration of CNS targeting drug candidates across the BBB, allow pre-screening and optimization strategies to be developed for new drugs and gene delivery formulations, and permit research groups to further understand how a dysfunctional BBB is involved in the pathogenesis of several neurological diseases.

The Tissue Engineering laboratory at the California Polytechnic State University, San Luis Obispo is currently in the process of developing a dynamic in …

A Proteomic Analysis Of Differentiation In The Mammary Epithelium, Laura Therese Strand

Master's Theses

While a great deal is known about the changing hormonal environment and the structural development of the mammary gland from pregnancy to lactation, very little is known about the molecular mechanisms governing differentiation of the mammary epithelium into a milk-secreting phenotype. It is important to acknowledge the diversity among the mammary glands of different species in order to better understand applications in human health and the dairy industry. In this study, we examined global protein expression during two states of differentiation in mammary epithelial cells from two species: in vitro proliferating and differentiated MAC-T cells (a bovine immortal cell-line), and …

Skin cancer is the most common form of cancer in the United States. In 2012 more than 68,000 Americans will be diagnosed with melanoma, 48,000 will be diagnosed with an early form of the disease that has not yet …

Seasonal Food Habits Of Burrowing Owls (Athene Cunicularia) In Human-Altered Landscapes, Carie Marie Wingert

Master's Theses

In 2004, I initiated a year-long study to investigate the food habits of burrowing owls (Athene cunicularia). Burrowing owls have been found in a variety of human-altered landscapes; however, little is known about burrowing owl food habits in urban landscapes. Burrowing owl food habits during the non-breeding season are also largely undocumented, despite increasing concern over the survival of overwintering burrowing owls. Differences in prey consumption between reproductive and non-reproductive owls during the breeding season have not yet been examined. I collected pellets over a 12 month period at four study sites affected by different levels of human …

Botanic Garden User Outcomes: A Means-End Investigation, Christopher Lee Wassenberg

Master's Theses

ABSTRACT

Botanic Garden User Outcomes: A Means-End Investigation

Christopher Lee Wassenberg

This study explored the outcomes that Leaning Pine Arboretum users experience from visiting the botanic garden. Understanding visitor motivations and benefits has been a focus in the field of outdoor recreation, and the subject of a number of botanic garden and green space visitor studies. Previous studies have found that visiting a botanic garden can serve as a coping strategy for dealing with and reducing life stress (Holbrook, 2010; Kohlleppel, Bradley, & Jacob, 2002; Maller, Townsend, Pryor, Brown, & St Leger, 2005) and that visiting public outdoor green spaces …

Development And Characterization Of Plga And Eptfe Blood Vessel Mimics Using Gene Expression Analysis, Michael Gibbons, Sarah Ur

Biomedical Engineering

Tissue engineered blood vessels (TEBV’s) have the potential to act not only as a replacement for diseased vessels, but also as a testing platform for intravascular devices such as stents. To this end, the goal of this study was to develop protocols for the construction of TEBV’s composed of human vascular cells and either expanded polytetrafluoroethylene (ePTFE) or poly-lactic-co-glycolic acid (PLGA), as well as a protocol for gene expression in those TEBV’s. Initial experiments involved only human umbilical vein endothelial cells (HUVEC’s), but after low cell confluency and spreading in single-sodded vessels a second cell type, human umbilical vein smooth …

Traversing Swanton Road, 8th Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

Korsgaard And Non-Sentient Life, Gregory L. Bock

Between the Species

Christine Korsgaard argues for the moral status of animals and our obligations to them. She grounds this obligation on the notion that we share a common identity, our animal nature, with them and that animal pain represents a public reason that binds us; nevertheless, her distinctive attempt to enlist Kantian arguments to account for our obligations to animals has a startling implication that she fails to adequately consider: that we have direct duties to plants as well.
