Father Convict Cichlids Bite Intruders More Often In Hot Temperatures, Jesse L. Heckendorf

STAR Program Research Presentations

Convict cichlids (Archocentrus nigrofasciatus) have evolved to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a male convict cichlid’s aggression toward caring for his offspring when an intruder is introduced. Male convict cichlids attack more in warmer water.

Characterizing Double And Triple Laser Beam Interference Patterns In The Context Of Trapping Atoms For Quantum Computing, Ian E. Powell

Physics

We propose two optical neutral atom traps for quantum computing involving the intersection of two or three laser beams. We simulate both the intensity and the potential energy of the interference pattern. From these simulations we create animations of how the potential energy and intensity change with varying angles of separation between the laser beams in the system. We parameterize lines through our interference pattern and fit simple harmonic oscillator potential energies to the potential energy wells calculated to characterize our interference pattern’s atom trapping capabilities. Finally, we investigate a possible quantum entanglement routine by observing how the geometry of …

Barriers To Adoption Of Methane Digester Technology On California Dairies, Desiree Lee Libarle

Master's Theses

The goal of this research was to analyze the barriers to adoption of methane digesters on California dairies. Methane digesters have long existed as a technology in the dairy industry, both in the United States and abroad. Much research has been done to attest to the viability and economic sustainability of methane digesters; however in 2014, there were 26 dairies in California that have methane digesters installed, and of these, only 17 of those were still in operation, according to the USEPA AgStar Anaerobic Digester Database. Hence, the question remains, as to why this technology has not been widely adopted …

Relative Expression Of Germination Genes Sleb, Gerac, And Gpr In Heat Treated Bacillus Licheniformis And Bacillus Subtilis, Valerie Paige Arechiga

Master's Theses

Endospore-forming bacteria of the genus Bacillus are of significant importance to the food industry. Species from this genus exhibit the ability to form metabolically dormant endospores characterized by resistance to heat, UV, and chemical treatment. Spores have undetectable metabolic activity and remain impervious to the harsh conditions of their environment, but they can detect environmental cues signaling favorable growth conditions and begin the process of germination. Once germination and outgrowth are complete, the fully viable cell is capable of reproducing and forming colonies. The resistance of these endospores has been a topic of decades of research, particularly because of their …

Root Stimulation Using Vermi-Products In Grape Vine Propagations, Katerina M. Flores

Wine and Viticulture

Vermi-products are byproducts produced from earthworms digesting and decomposing a natural material into another. Liquid teas or extracts of vermi-products are another form of leachate material found in the completed compost bin. These products are not high in essential plant macronutrients, have an average neutral pH (around 7.0), and are known for living microbial population. Grapevine propagations cut from the Trestle Vineyard at California Polytechnic State University, San Luis Obispo were used to observe root growth development using steer compost, vermicompost, and vermi-extract. Propagations used were dormant Pinot Noir clone 777. Compost subsamples tested 5%, 10%, 20%, and 40% by …

Photobioreactor Design For Improved Energy Efficiency Of Microalgae Production, Alexander Burns

Master's Theses

ABSTRACT

Photobioreactor Design for Improved Energy Efficiency of Microalgae Production

Alexander Burns

The objective of this research was to investigate a new photobioreactor (PBR) design for microalgae production that retains the typical advantages of existing tubular PBRs while reducing power consumption by providing simultaneous culture circulation and gas exchange with airlift alone and no centrifugal recirculating pump. Traditional tubular PBR designs feature a compressed air supply and a centrifugal pump for culture circulation and gas exchange. Circulation and gas exchange in a closed-system PBR is necessary to keep the algae suspended and to provide sufficient mass transfer (mainly for the …

Growth Media And Lipid Determination Comparison Of High Rate Algae Ponds, Eric Alexander Nicolai

Master's Theses

Growth Media and Lipid Determination Comparison

of High Rate Algae Ponds

Eric Alexander Nicolai

The feasibility of algal biofuel production relies on the use of a non-potable water source. Municipal wastewater is nutrient-rich and a cost effective option as a growth media in algae ponds. However, this resource may be too valuable for algal biomass production, as reclaimed wastewater is needed for surface irrigation and groundwater recharge. This thesis compares the performance of 4.2 m² high rate algal raceway ponds (HRAPs) to 33 m² HRAPs grown on primary settled wastewater during a media recycling study and a growth …

Evaluating Five Years Of Soil Hydrologic Response Following The 2009 Lockheed Fire In The Coastal Santa Cruz Mountains Of California, Mary Theresa Crable

Master's Theses

The Lockheed Fire burned 31 km² (7,660 acres) of the Scotts Creek watershed in August 2009. 4.5 km² (1,100 acres) of California Polytechnic State University’s educational and research facility at Swanton Pacific Ranch. The burned region presented an opportunity for studying the hydrologic response of burned soils in the Santa Cruz Mountains where there is insufficient post-fire studies regarding fire-effects on watershed processes such as infiltration and near-surface runoff. Soil infiltration and soil water repellency were evaluated with rainfall simulations, Mini-disk Infiltrometer (MDI) and water drop penetration time tests (WDPT) at sites represented by variations in burn severity, …

Wildlife Deterrence Method Test Device, Garrett Tietz, Adam Webb, Dane Knutson

Mechanical Engineering

The objective of the Deer Busters team is to design and build a device or system of devices that will be used to determine which method, or methods, are most effective at deer deterrence. JumpSport suspects that a method which gives the appearance of approach to the deer in an aggressive or startling manner but also changes the way it attacks so that the deer do not get used to the device will be most effective. Deer Busters is committed to the completion of the deer deterrent testing device by the end of the fall quarter of 2014.

Vascular Reactivity In Newly-Formed And Mature Arterialized Collateral Capillaries, Sara K. Hellstrom

Master's Theses

Peripheral arterial occlusive disease (PAOD) is a globally-prevalent cardiovascular disease in which atherosclerotic plaques narrow arterial lumen diameters and restrict blood flow to downstream tissues. The impact of these occlusions can be mitigated by collateral vessels that connect parallel arterial branches and act as natural bypasses to maintain perfusion. In animal models that lack collateral arterioles, capillaries that connect terminal arteriolar segments can arterialize and form functional collaterals following an ischemic event; however, in the early stages of development, vasodilation is impaired. We explored the mechanism of impaired vasodilation in arterialized collateral capillaries (ACCs) and pre-existing collaterals (PECs) by evaluating …
