The Effects Of Cluster Thinning On Vine Performance, Fruit, And Wine Composition Of Pinot Noir (Clone 115) In The Edna Valley Of California, Paul F W Mawdsley Sep 2019

The Effects Of Cluster Thinning On Vine Performance, Fruit, And Wine Composition Of Pinot Noir (Clone 115) In The Edna Valley Of California, Paul F W Mawdsley

Master's Theses and Project Reports

A three-year study was conducted at a commercial vineyard site in California’s Edna Valley AVA to evaluate the physiological and agronomical effects of the timing of cluster thinning on Pinot noir (clone 115) grapevines. Vines were thinned to one cluster per shoot at three selected time-points during the growing season (bloom, bloom + 4 weeks, bloom + 8 weeks), and fruit from each treatment was harvested and made into wine. Across all growing seasons, yield decreased 43% in thinned vines relative to un-thinned control vines. No effect of cluster thinning or interaction with growing season was found in vine shoot diameter ...


Examining The Effectiveness Of Electromyography Biofeedback At Improving The Upper Trapezius To Serratus Anterior Muscle Activation Ratio, Julia Evelyn Holton Aug 2019

Examining The Effectiveness Of Electromyography Biofeedback At Improving The Upper Trapezius To Serratus Anterior Muscle Activation Ratio, Julia Evelyn Holton

Master's Theses and Project Reports

Purpose: The upper trapezius to serratus anterior muscle activation ratio is essential for optimal shoulder function. An alteration of this ratio, specifically a decrease in upper trapezius and increase in serratus anterior activation, is a main area of focus in shoulder rehabilitation (Kibler, 1998; Paine & Voight, 1993). Electromyography (EMG) biofeedback has been shown to be an effective rehabilitation technique to address many musculoskeletal disorders but there is limited research on the retention of improvements seen with EMG biofeedback (Ma et al., 2011; Lim et al., 2014; Weon, et al., 2011). The purpose of this study was to determine if EMG biofeedback can be used to improve scapular control by decreasing the upper trapezius to serratus anterior activation ratio. A secondary purpose was to determine if these predicted improvements in the ratio can be retained beyond the timeframe ...

Three field trials were conducted in a commercial Pinot Noir vineyard in San Luis Obispo, California; the effects of (i) fertilizer type (organic and inorganic), (ii) weed management (herbicide and tillage), and (iii) cover crops (high or low water requirements) on nematode community structure, soil nutrient content ...


Development Of A Prolyl Endopeptidase Expression System In Lactobacillus Reuteri To Reduce The Clinical Manifestation Of Celiac Disease, Kara Lynn Jew Jul 2019

Development Of A Prolyl Endopeptidase Expression System In Lactobacillus Reuteri To Reduce The Clinical Manifestation Of Celiac Disease, Kara Lynn Jew

Master's Theses and Project Reports

Celiac Disease (CD) is an autoimmune disorder that emerges due to the ingestion of gluten, a protein found in a variety of common grains such as wheat, rye, and barley. Approximately 1 in 100 individuals in the US suffer from CD, making it the most commonly diagnosed gastrointestinal disorder (Ciclitira et. al., 2005). These proline-rich gluten peptides are resistant to proteolysis and accumulate in the duodenum of the small intestine. Once in the duodenum, these peptides illicit an autoimmune response resulting in villous atrophy. Current treatment for CD requires a rigorous adherence to a gluten-free diet. Nevertheless, gluten-containing grains are ...

Rescue And Rehabilitation Of A Juvenile Red-Tailed Hawk: A Case Study, Maya Higa Jun 2019

Rescue And Rehabilitation Of A Juvenile Red-Tailed Hawk: A Case Study, Maya Higa

Agricultural Education and Communication

Many raptor species are becoming threatened and, in some cases, endangered as a result of human activity including habitat destruction and pesticide use (Morishita, Fullerton, Lowenstine, Gardner & Brooks, 1998). Because of this, raptor rehabilitation has become increasingly popular in conservation efforts. In North America, the red-tailed hawk is one of the most widespread and commonly known birds of prey (Preston & Beane, 2009). According to the National Audubon Society, the conservation status of red-tailed hawks is currently of least concern and numbers may even be increasing in some areas since the 1960s. While this species is not threatened, the conservation of ...

Compositional Optimization Of Amyloid-Graphene Oxide Nanohybrids For Biomaterials, Claire L. Drewery

Materials Engineering

Amyloid nanofibrils are natural materials capable of self-assembling into precise structures with tunable functionalities, while exhibiting excellent mechanical properties. In combination with highly conductive graphene oxide (GO), the 1-D amyloid nanofibrils and 2-D nanosheets of GO can produce a robust and bio-functional nanohybrid, hypothesized to exhibit multi-domain functional properties useful for enzyme sensing, water purification, drug delivery, and tissue scaffolding applications. Here, we examine the properties of an amyloid-graphene oxide nanohybrid film made with amyloids derived from hen egg white lysozymes in an attempt to explore the diverse toolbox of amyloid derivatives and establish ideal fabrication methods and formulations of ...


Availability Of Microtrash Materials And Selectivity By California Condors, Marie G. Solis Jun 2019

Availability Of Microtrash Materials And Selectivity By California Condors, Marie G. Solis

Biological Sciences

California condors consume non-food items, including anthropogenic waste, and provision it to their young. Consuming “microtrash” can cause mortality, especially in nestlings. There are several hypotheses explaining why condors might consume microtrash. These hypotheses assume condors exhibit a preference for the type of material. Therefore, we test the assumption that when California condors take microtrash, they display material selectivity. We did this by sampling microtrash from roadside pullouts in the Los Padres National Forest. Those samples were compared to condor necropsy and nest microtrash data, categorized by material type: glass, plastic, metal, and other. We find that in our analysis ...
