Effects Of Extreme Starvation On The Fasting-Adapted Western Rattlesnake (Crotalus Oreganus), Brandon R. Kong

Master's Theses

Ambush-hunting snakes have long been of great interest in the biology of fasting and starvation, as they are adapted to withstand well over a year without taking a meal. Well-justified ethical constraints have limited our understanding of their biology at the limits of these abilities. Unfortunate circumstances, in which the California Department of Fish and Wildlife confiscated over 50 Western Rattlesnakes (Crotalus oreganus) from an animal hoarder that had long neglected them, culminated in the euthanized animals ending up in the hands of our lab. Some of these snakes were extremely starved, being only one-half to one-third of …

Effect Of Enzymatic Pretreatment On Biomethane Production From Olive Pomace, Ningjing Zhong

Master's Theses

In 2023, approximately 2.36 million metric tons of olive oil were produced globally. Olive pomace, a byproduct of the flesh and pits left after olive oil extraction, presents environmental challenges when used as landfill due to its high polyphenol and organic contents, or when combusted due to greenhouse gas emissions. Its potential as animal feed is limited, yet it holds promise for methane production via anaerobic digestion (AD), providing a source of renewable energy. However, the highly crystallized polysaccharides in olive pomace, such as cellulose, hemicellulose, and pectin, impede its conversion to methane, and the high polyphenol content inhibits methanogen …

A Study On The Effects Of Cementless Total Knee Arthroplasty Implants’ Surface Morphology Via Finite Element Analysis, Scott Hazelwood, Peter J. Hunt, Mohammad Noori, Naudereh B. Noori, Wael A. Altabey

Biomedical Engineering

Total knee arthroplasty (TKA) is one of the most commonly performed orthopedic surgeries, with nearly one million performed in 2020 in the United States alone. Changing patient demographics, predominately indicated by increases in younger, more active, and more obese patients undergoing TKA, poses a challenge to orthopedic surgeons as these factors present a greater risk of long-term complications. Historically, cemented TKA has been the gold standard for fixation, but long-term aseptic loosening continues to be a risk for cemented implants. Cementless TKA, which relies on the surface morphology of a porous coating for biologic fixation of implant to bone, may …

San Luis Obispo In A Box: Damage Accumulation And Combined Stressor Matching In Accelerated Uv Testing, Cameron N. Causey

Master's Theses

The goal of service life prediction is to accurately predict the useful lifetime of a coating system in a typical service environment. Field testing is the most true-to-life form of service life testing but requires long exposure times, often not quick enough to readily aid redesign in the product development cycle. As an alternative, accelerated weathering chambers are used to speed up coating failure in a laboratory setting. These devices do indeed accelerate failure but often produce failure modes that are not seen in actual service or produce material rankings that are not reproducible. This work explores the principle of …

The Effect Of Watts-Strogatz And Barabási-Albert Graphs On Memory Formation, Ethan Irick Wolfe

Master's Theses

Understanding higher level cognitive processes is a central problem in neuroscience. The Neuroidal model provides a useful framework for posing these problems in a computer science context. There has been significant recent work trying to understand memory capacity in the Neuroidal model but this work was done assuming that the network of neurons was an Erdos-Renyi random graph. However the network of neurons in the brain has been shown to exhibit small-world properties, which are not present in Erdos-Renyi graphs. In this research we explore replacing Erdos-Renyi graphs with Watts-Strogatz and Barabasi-Albert graphs in order to more accurately model the …
