Cultivar And Nutrient Management Effects On Disease Resistance And Nutrient Use Efficiency In Strawberries, Kate Worrell

Baker/Koob Endowments Awarded Projects

In this research project we utilizing different amounts of compost N in four specific strawberry cultivars to minimize Macrophomina phaseolina in strawberries a disease that causes plant mortality due to crown rot. We had been assuming that adding compost N will lead to a decrease in the disease rates and help the strawberries grown better than they would without the compost. We found that in general looking at the graphs related just to treatment compost was found to be just as effective as CFR. In some cases, compost was even less effective as seen in the graph of Fig.2. CRF …

Suspicion Encoded: Women Of Color And Biometric Technology In The United States, Lilith A. Saylor

sprinkle: an undergraduate journal of feminist and queer studies

This paper explores the commodification of privacy through biometric technology in the United States. It examines the impact of this technology on poor women of color (WOC), arguing that poor WOC face intersectional discrimination based on the convergence of sex, race, and class in their identities. I highlight the unique and powerful intrusion of biometric technology into the lives of poor WOC, and argue that the connection between data and the physical body created through biometric data has formed an environment in which the state wields unrestricted control in all spheres over the privacy of poor WOC.

The Boy In The Mirror: A Tale Of Radical Queer Muslim Liberation, Shariq I. Farooqi, Khansa Noor

sprinkle: an undergraduate journal of feminist and queer studies

This photo-series & its connected narrative captures the ornate reality of identifying as a Queer Muslim of color. The photos were beautifully curated by a photographer and dear friend of mine, Khansa Noor. The images are meant to visually conceptualize how queerness can manifest outwardly in one's bodily expressions and demeanor. The guilt, shame, and relief that I described in the narrative translates intimately in my brown skin and my movements. Both pieces merge to illustrate the layers of queer Muslim survival in concealing one's queerness while simultaneously remaining unequivocally bold in queer spaces.

Effects Of Estuary-Wide Seagrass Loss On Fish Populations, Jennifer K. O'Leary, Maurice C. Goodman, Ryan K. Walter, Kariss Willits, Daniel J. Pondella

Physics

Globally, habitat loss in coastal marine systems is a major driver of species decline, and estuaries are particularly susceptible to loss. Along the United States Pacific coast, monospecific eelgrass (Zostera marina) beds form the major estuarine vegetated habitat. In Morro Bay, California, eelgrass experienced an unprecedented decline of > 95%, from 139 ha in 2007 to < 6 ha by 2017. Fish populations were compared before and after the eelgrass decline using trawl surveys. Beach seines surveys were also conducted during the post-decline period to characterize species within and outside of remnant eelgrass beds.While the estuary-wide loss of eelgrass did not result in fewer fish or less biomass, it led to changes in species composition. The post-eelgrass decline period was characterized by increases in flatfish (mainly Citharichthys stigmaeus) and staghorn sculpin (Leptocottus armatus), and decreases in habitat specialists including bay pipefish (Syngnathus leptorhynchus) and shiner perch (Cymatogaster aggregata). There were similar trends inside and outside of remnant eelgrass patches. These findings support evidence across multiple ecosystems suggesting that the predominance of habitat-specialists predicts whether or not habitat loss leads to an overall decline in fish abundance. In addition, loss of critical habitats across seascapes can restrict population connectivity and lead to range contraction. For bay pipefish, the loss of eelgrass in Morro Bay is likely to create a population biogeographic divide. Currently, Morro Bay is dominated by flatfish and sculpins, and the longevity of this new ecosystem state will depend on future eelgrass recovery dynamics supported by ecosystem-based management approaches.

Effect Of Simulated Storage And Distribution On Listeria Innocua Growth In Non-Traditional Salad Ingredients, Emma L. Sandquist

Master's Theses

The fresh-cut produce industry has seen expansive growth in recent years, to meet consumer demand ready-to-eat (RTE) salads have included the use of non-traditional ingredients. Uncommon ingredients include beet greens, kale, broccoli stalk, and Brussels sprouts, since these ingredients have not historically been consumed raw, potential food safety issues should be reassessed. Current processing technologies include produce washes that can reduce microbial levels but do not eradicate all populations. The lack of a kill step in produce processing emphasizes the need to minimize pathogen contamination during production and growth during a product’s shelf life. Listeria monocytogenes, a leading cause …

Estimating Food Waste Due To Food Safety Recalls And Investigating Ways To Minimize Negative Impacts, Mykayla Latronica

Master's Theses

For years the issue of food waste has been recognized and quantified; however, food safety issues often go unrecognized as a source of food waste. One objective of this research is to estimate quantities and monetary value of fruits and vegetables implicated in food safety recalls, and thus wasted. Using publicly available data we identified all recalls involving vegetable or fruit commodities contaminated with Listeria monocytogenes, pathogenic E. coli, or Salmonella during 2015-2018. When quantities were provided, monetary value of recalled product was calculated using USDA ERS 2016 average retail prices. Although data limitations only allowed analysis of …

The West End: Redevelopment Of The Westminster Mall, Christopher Cortez

City and Regional Planning

The purpose of this project is to create a redevelopment plan for the Westminster Mall in Westminster, CA that will successfully reinvigorate itself as an active and vibrant center for the city.

Redeveloping malls and the property they sit on is a prominent planning issue. Malls are becoming less popular commercial centers and must adapt to fulfill the local community’s needs. This can be accomplished through changes to the volume of commercial space and introducing new land uses, such as multifamily residential and open space, all of which are planning methods.

This project will explore how North American Malls, such …

Ecg Arrhythmia Classification Using Discrete Wavelet Transformation, Hannah E. Chookaszian, Nathan D. Diekema

Electrical Engineering

Cardiovascular diseases (CVDs) are the highest leading cause of death worldwide with an approximate 17.9 million related deaths every year according to the World Health Organization (WHO). Electrocardiographic (EKG or ECG) signals are electrical signals measured in the heart and are the main indicator for pre-existing cardiac conditions. The application of deep learning methods such as artificial neural networks (ANN) will assist in the automated detection and classification of ECG signals. The current methods for ECG analysis are lacking in accuracy and reliability considering the level of risk involved with CVDs and the importance of a correct diagnosis. Clinicians use …

This chamber allows for students to test material properties under a variety of thermal conditions. This project was done in collaboration with a team working on the structural aspect of the chamber. While consumer environmental chambers are on the market, they often cost more than $50,000. Additionally, our chamber conforms to further size and weight constraints. Because of this constraint, many conventional techniques and components used for these chambers are not feasible for our …

The Medicalisation Of Gender Nonconformity Through Language: A Keywords Analysis, Angelo Cosma Galluzzo

sprinkle: an undergraduate journal of feminist and queer studies

Language is an important part of the way gender nonconformity is legislated and medicalised. In 2012, the American Psychiatric Association (APA) changed the nomenclature of the ‘gender identity disorder’ (GID) to ‘gender dysphoria in the ‘Diagnostic and Statistical Manual of Mental Disorders (DSM) to reduce the social stigma attached to transgender identities. While the recognition of gender nonconformity by the medical authorities has led to some beneficial consequences, scholars have shown that the language of pathology has narrowed the definitions of gender nonconformity and has created social stigma. I use the web pages of five major health providers of English-speaking …

Eelgrass (Zostera Marina) Populatin Delcine In Morro Bay, Ca: A Meta-Analysis Of Herbicide Application In San Luis Obispo County And Morro Bay Watershed, Tyler Sinnott

Master of Science in Environmental Sciences and Management Projects

The endemic eelgrass (Zostera marina) community of Morro Bay Estuary, located on the central coast of California, has experienced an estimated decline of 95% in occupied area (reduction of 344 acres to 20 acres) from 2008 to 2017 for reasons that are not yet definitively clear. One possible driver of degradation, that has yet to be investigated is the role of herbicides from agricultural fields in the watershed that feeds into the estuary. Thus, the primary research goal of this project was to better understand temporal and spatial trends of herbicide use within the context of San Luis Obispo (SLO) …

Preliminary Survey Of Herbicide Environmental Fate And Transport In California And The Morro Bay Watershed Environment, Alexandra Carlson

Master of Science in Environmental Sciences and Management Projects

Seagrasses are rapidly declining around the globe as well as in Morro Bay, CA. Between 2007 and 2017, the Morro Bay Estuary experienced a 97% loss of seagrass meadows. The cause of the decline is unknown. A potential cause for the loss of seagrass meadows is the degradation of seagrass habitat in the bay because of contamination due to the use of herbicides. Some examples of herbicides used within the watershed include: Oxy uorfen, Diuron, Simazine, Napropamide, Oryzalin, Chlorthal-Dimethyl, Glyphosate and Tri uralin. Theses herbicides are all highly used within the watershed and are on the top 10 list for …

Electrical Engineering

The technology of photovoltaics has been quickly evolving as we move toward a future with more clean energy. Energy conversion efficiency is key to making these systems the viable option amongst other sources of power. This project proposes a way to increase the power yield from a solar system by implementing smarter algorithms in the maximum power point tracking (MPPT) component of the system. MPPT is critical because environmental conditions may vary significantly for any given system due to irradiance and shading. The proposed method for MPPT utilizes a controller that uses swarm intelligence to do the power tracking.. This …

Oceanside Transit Center Transit-Oriented Development (Otc Tod): Revisioning North San Diego's County Transit Hub, Chad Johnston

City and Regional Planning

Many California coastal communities lack a supply of housing, produce high levels of greenhouse gas emissions by daily auto commuters but have existing local and commuter rail stations with large fields of parking surrounding it. Transit-Oriented Development (TOD) integrates the building of housing, retail, office, and public space together focused around transit stations. This infill of development locates people within comfortable walking distance, usually within a quarter-mile, of a public trail transit station reducing automobile dependence for local trips or commuting for work.

The Oceanside Transit Center (OTC) is a major railway interchange, serving as a gateway to the San …

Envrment: Investigating Experience In A Virtual User-Composed Environment, Matthew Key

Master's Theses

Virtual Reality is a technology that has long held society's interest, but has only recently began to reach a critical mass of everyday consumers. The idea of modern VR can be traced back decades, but because of the limitations of the technology (both hardware and software), we are only now exploring its potential. At present, VR can be used for tele-surgery, PTSD therapy, social training, professional meetings, conferences, and much more.

Dc-Dc Buck-Boost Converter Design For Energy Harvesting From Exercise Equipment, Nicholas Serres

Electrical Engineering

This project aims to improve energy harvesting efficiency from an exercise machine. Exercise machine energy harvesting has a small immediate impact but can eventually have an immense impact. An elliptical exercise machine energy converter outputs 5V-60V whereas the microinverters require approximately 36V. The buck boost DC-DC converter bridges the gap between the microinverter and the elliptical machine. Increasing the buck-boost controller efficiency increases power production. Greater power efficiency gives the whole system more financial viability, and additionally makes it a greater sustainable energy source.

Dc House Network Design And Modeling, Timmy Huu Nguyen, Joseph Shafie

Electrical Engineering

Although electricity is a necessity for nearly everything in daily life, many developing countries are unable to provide easy access to this utility. Often times within these developing countries, many renewable energy sources exist that are readily accessible to these same people that don’t have access to electricity within their homes, such as solar energy. However, the nature of renewable energy is that most renewable energy lacks consistency in power delivery throughout the day. An example of this is that solar energy isn’t available during the night. These small communities are often comprised of people that are familiar with each …

Analysis Of Electroanatomic Mapping System Accuracy Using X-Ray Reconstruction Of Electrode Locations In A Porcine Animal Model, Hana Boudlali

Master's Theses

Fluoroscopy is considered the gold standard for locating catheters during cardiac electrophysiology (EP) procedures. However, fluoroscopy emits ionizing radiation which can lead to adverse health effects when exposed to in high doses (World Health Organization, 2016). Electroanatomic mapping (EAM) systems display the three-dimensional location of EP catheters and measure the local electrical activity of the heart. They can minimize a physician’s reliance on fluoroscopy and can help reduce radiation exposure during a case (Casella, 2011).

EAM systems are diagnostic medical devices that inform the placement of ablation therapy and must accurately locate catheters to be deemed safe. Test methods to …

Phantom Ocean, Real Impact: Natural Surf Sound Experiments Alter Foraging Activity And Habitat Use Across Taxa, Ryan N. Wardle

Master's Theses

A growing body of research focuses on how background sounds shape and alter critical elements of animals’ lives, such as foraging behavior, habitat use, and ecological interactions (Bradbury & Vehrencamp, 2011; Barber et al., 2010; Kight & Swaddle, 2011; Shannon et al., 2016). Much of this research has centered on the effects of anthropogenic noise (Dominoni et al., 2020; Francis & Barber, 2013; Ortega, 2012; Swaddle et al., 2015), but recent studies have also revealed that natural sound sources can influence animal behavior (Davidson et al., 2017; Le et al., 2019). Natural sounds, such as crashing surf, can create conditions …
