The overall objective is to connect the visitors with the marvels and wonders of the natural resources at Glacier Point in Yosemite National Park, California. This …

Budget Analysis For A Napa County Vineyard, Christopher Jan Hyde

Agribusiness

This study was undertaken to determine whether farming premium wine grapes can generate profit on a 10 acre site in Napa County, and if farming wine grapes can be a profitable long term investment.

The report utilizes two techniques for analysis of the data. The break-even analysis will be used to determine whether the operation is potentially profitable. Vineyard establishment costs were outlined in and production costs (from year 3 forward) defined. Production costs and grape revenues are weighed to determine net revenues above total costs. Monthly per acre break down of costs demonstrates how vineyard production costs fluctuate during …

Bacteria - The Last Stronghold Of Lamarckism?, William D. Stansfield

Biological Sciences

French naturalist J.B. Lamarck is most commonly known for popularizing the theory that some traits acquired during the life of an organism can be inherited in his 1809 book. German biologist A. Weismann presented evidence in his 1891 book that acquired traits were not heritable in sexually reproducing animals. But so little was known about bacteria that they were considered to be the last stronghold of Lamarckism. The “fluctuation test” of S. Luria and M. Delbrück in 1943 seemed to confirm that Lamarckism in bacteria was indeed dead. This review, however, proposes that today bacteria may be viewed as the …

Effect Of Sand Grain Size On Burrowing Behavior Of Juvenile Pacific Sand Crabs (Emerita Analoga), Natalie A. Lee, Laura M. Melroy

Biological Sciences

Emerita analoga, Pacific coast sand crabs, are an important biological component of the swash zone ecosystem. They have evolved the ability to burrow into sand, and burrowing speed is commonly used as an indicator of performance relevant for fitness in this species. Sand grain size varies among beaches, and crabs may be better adapted to to burrow in some sand types. We performed a completely crossed 3-factor experiment to determine how the sand grain size associated with beach-of-origin and rearing conditions influence burrowing in coarse and fine sand. Crabs from a fine sand beach and a coarse sand beach were …

Evaluation And Design Of A 20-Acre Avocado Orchard, Daniel Holtz

BioResource and Agricultural Engineering

Rocky H Ranch is a 120 acre avocado farm located in Escondido California. There is a 20 acre parcel that has not been planted. The roads, trees, and irrigation system were designed to maximize yields and irrigation system performance while utilizing the latest technology.

Roads were laid out along the contours to maintain block sizes to an average length and width. This is done for two reasons, ease of harvesting and so the irrigation laterals are not excessively long. Nine blocks, or where roads surrounded trees, were created. The trees were laid out along the contours at a 15 foot …

Identifying Alternative Waste Conversion Technologies For Use At California Polytechnic State University San Luis Obispo, Matthew R. Bono

BioResource and Agricultural Engineering

This project was undertaken to identify and study alternative technologies for converting waste streams available on the Cal Poly San Luis Obispo campus into energy. As a large campus on the Central Coast of California Cal Poly not only produces lots of waste, but has limited options for its disposal. Furthermore, the campus is in the midst of an on-going green initiative, and more efficient use of its waste products would be a welcome development for the entire campus community. This report gathers information on waste streams originating at Cal Poly and information about waste to energy conversion technologies. The …

Exploring The Relationship Of The Closeness Of A Genetic Algorithm's Chromosome Encoding To Its Problem Space, Kevin Mccullough

Master's Theses

For historical reasons, implementers of genetic algorithms often use a haploid binary primitive type for chromosome encoding. I will demonstrate that one can reduce development effort and achieve higher fitness by designing a genetic algorithm with an encoding scheme that closely matches the problem space. I will show that implicit parallelism does not result in binary encoded chromosomes obtaining higher fitness scores than other encodings. I will also show that Hamming distances should be understood as part of the relationship between the closeness of an encoding to the problem instead of assuming they should always be held constant. Closeness to …

Cal Poly Organic Farm Business Plan, Eric Ryan Mccarthy

Agribusiness

This study was undertaken to determine which strategies would allow the Cal Poly Organic Farm to operate as a profitable business without compromising educational and agricultural objectives. Three strategies were analyzed to determine the most profitable approach. The first strategy, expanding CSA sales, emphasizes marketing efforts to increase products and services awareness. This should increase CSA, CPOF, merchandise, and farmers’ markets sales. The second strategy implements new CSA produce boxes that cater to specific groups. Existing produce boxes will remain available to CSA members. Expanding produce boxes can be done with the produce on hand or expanding crop selection. The …

Foraging Rates Of Larval Dragonfly Colonists Are Positively Related To Habitat Isolation: Results From A Landscape-Level Experiment, Shannon J. Mccauley, Tomas Brodin, John Hammond

Biological Sciences

There is increasing evidence of intraspecific variation in dispersal behavior. Individual differences in dispersal behavior may be correlated with other traits that determine the impact individuals have on patches they colonize. We established habitat patches—artificial pools—across a landscape, and these pools were naturally colonized by dragonfly larvae. Larvae were collected from pools at different levels of isolation and held under common lab conditions for 5 months. We then compared larval foraging rates. Foraging rate was positively related to habitat isolation, and colonists from the most isolated artificial pools had significantly higher foraging rates than individuals from the least isolated pools. …

The "Broken Home" Or Broken Society: A Sociological Study Of Family Structure And Juvenile Delinquency, Hillary R. Sheehan

Social Sciences

Despite the great interest in the relationship between family structure and delinquent behavior generally, very little agreement among researchers as well as the general public has been reached on the issue to this day. The present study examines whether family structure plays a role in juvenile delinquency. More precisely, it explores whether single parents are more likely to have their adolescent children involved in delinquency than are two parents. This analysis does not support the structural hypotheses, which argues that single parents have children who are at an increased risk of being involved in delinquent behavior. While these findings provide …

Climate Change And Human Health Consequences, Jennifer Alford

Social Sciences

The intent of this project is to highlight the human health ramifications of climate change and the strategies for coping with this challenge. Possible effects may include reduction in agricultural outputs, dwindling freshwater aquifers, intensification of tropospheric ozone, and expanding areas of disease-carrying vectors. Because humans are closely connected with their environment, we are directly affected by any environmental disturbance. Consequently, human health is vulnerable to the effects of climate change. The questions are: what are those consequences, how will we adapt, and what does the future hold?

The Implementation Of A Conceptually Coherent Curriculum Within A Constructivist Preschool Environment, Heather Jones, Sarah Post

Psychology and Child Development

Creating a learning environment that enchants children’s curiosity and sparks exploration, discovery, and thought does not require a great amount of financial resources. Rather, one must concentrate on observation and focus on building on children’s existing interests in the natural world. The research and theories of Swiss psychologist and philosopher, Jean Piaget, and Russian Psychologist, Lev Vygotsky provide a concrete look into a child’s cognitive and social development and can be informative in creating such environments. Using the developmental knowledge presented in these theories, programs such as the Reggio Emilia program, the Preschool Pathways to Science program (PrePS), and the …

Temperature Affects Adhesion Of The Acorn Barnacle (Balanus Amphitrite), Laurel A. Johnston

Master's Theses

Biofouling is the accumulation of sessile marine organisms, such as algae, tube worms and barnacles on man-made substrata and has negative economic and ecological implications. Ship hulls are readily fouled, which significantly increases drag while decreasing ship fuel efficiency when moving through water. Fouled hulls have also become important vectors of invasive species. These problems are minimized when hulls are painted with a toxic anti-fouling or non-toxic foul-release coating. Due to recent restrictions of anti-fouling paint use, research and development of non-toxic alternatives has increased.

Novel hull coating efficiency is often quantified by the critical removal stress value of barnacles …

This study was divided into three sections. The first section involved testing a DrainPacTM filter for treatable flow rates, head loss, and removal of solids, oil, and bacteria. The DrainPacTM filter is designed to be installed in a stormwater catch basin. The filter is composed of a 12 x 41 inch metal frame with textile filter media attached to it in a basket shape. The upper portion of …

Developing A Source Water Protection Plan For Boron In The San Luis Obispo County Water Supply, Jenny Macartney

Master's Theses

The goal of this project is to design a feasible way to develop a protection plan for boron in the surface waters and groundwater of San Luis Obispo County. Boron is a micronutrient needed by all plants and animals but the threshold for toxicity in plants is narrow. As the need for water increases and the production of wastewater and irrigation water infiltrates the soil and waters of the County, an understanding of background soil and water concentrations, as well as anthropogenically produced sources of boron must be quantified and mapped so that intelligent planning decisions can be made.

Precision Systems' Micro-Osmette located in the St. Jude Lab at Cal Poly SLO is a freezing-point depression osmometer capable of measuring the osmolality, the concentration of hydrated species in osmoles per-kilogram of water, with unrivaled speed and accuracy. The Osmette could be used extensively by students in a wide variety of applications if students are able to become acquainted with the device in an accelerated manner. The amount of time required to safely and effectively operate the micro-Osmette using the operator's manual provided with the device is prohibitive of widespread use by students. Revisions and improvements to the existing operator's …

Variation In The Heat Shock Response And Its Implication For Predicting The Effect Of Global Climate Change On Species' Biogeographical Distribution Ranges And Metabolic Costs, Lars Tomanek

Biological Sciences

The preferential synthesis of heat shock proteins (Hsps) in response to thermal stress [the heat shock response (HSR)] has been shown to vary in species that occupy different thermal environments. A survey of case studies of aquatic (mostly marine) organisms occupying stable thermal environments at all latitudes, from polar to tropical, shows that they do not in general respond to heat stress with an inducible HSR. Organisms that occupy highly variable thermal environments (variations up to >20°C), like the intertidal zone, induce the HSR frequently and within the range of body temperatures they normally experience, suggesting that the response is …
