Relationship Between Habitat Variables And Leopard Shark (Triakis Semifasciata) Population Trends In The South San Francisco Estuary, Patrice Frazier

Master's Theses

The San Francisco Estuary (the Estuary) supports a diversity of native marine species, including the leopard shark (Triakis semifasciata). As the human population has increased in the Bay Area, elasmobranchs have simultaneously been subjected to habitat loss and changes in hydrology. On a large scale, global climate change is also affecting the Estuary's water quality. There is little research on the long-term population size of leopard sharks in the Estuary. Leopard shark catch data collected by the Marine Science Institute (MSI) and water quality data from the United States Geological Survey (USGS) from 1998 to 2017 were analyzed to assess …

New Functional Groups For Sadmet Polymerization, Hasaan Rauf Dec 2019

New Functional Groups For Sadmet Polymerization, Hasaan Rauf

Master's Theses

Olefin metathesis is one of the most widely used methods for the formation of carbon-carbon double bonds. Acyclic diene metathesis (ADMET) polymerization has been extensively used in the synthesis of precision polymers by using well-defined monomers to form unique polymer morphologies with intriguing physical properties. Traditional ADMET polymerization cannot be used to synthesize block or alternating polymers. Selective acyclic diene metathesis (SADMET) polymerization synthesizes a polymer with non-reactive backbone double bonds by sequentially reacting electron deficient α,ω-dienes with the reactive internal olefin bonds to form block and alternating polymers. To date, only acrylates have been widely utilized as the electron …

Electrical Characterization Of Blood Clots, William Mcgrath Dec 2019

Electrical Characterization Of Blood Clots, William Mcgrath

Master's Theses

This work reports the use of dielectric spectroscopy to study blood and blood clots. A test setup was developed and electrode behavior was characterized with water and salt solutions. By measuring changes in electrical permittivity, trends differentiating clotting and non-clotting blood were identified. Non-clotting blood exhibited an increase in normalized permittivity at high frequencies that is credited to the sedimentation of red blood cells (RBCs) in static blood samples. Clotting blood was found to show a decrease in permittivity after some time at high frequencies. This is associated with the aggregation of red blood cells. Platelet rich plasma (PRP) and …

Summer Habitat Used By American Kestrels In Santa Clara County, California, Nicole Tomes Dec 2019

Summer Habitat Used By American Kestrels In Santa Clara County, California, Nicole Tomes

Master's Theses

Urbanization can be a primary source of the loss of native species populations by causing habitat loss, fragmentation and land conversion (Tilman et al., 2001; Krauss et al., 2010; Marzluff, 2001). Birds of prey, which are mid or top carnivores, are especially at risk from the loss of habitat that can occur on both the breeding and wintering grounds. Raptors can be considered environmental indicators of habitat degradation because of their small populations, low population densities, and high position in local food webs. This research investigated the habitat preference of the American Kestrel (Falco sparverius) (kestrel), a widely distributed raptor, …

Non-Invasive Hyperglycemia Detection Using Ecg And Deep Learning, Renato Silveira Cordeiro Dec 2019

Non-Invasive Hyperglycemia Detection Using Ecg And Deep Learning, Renato Silveira Cordeiro

Master's Theses

Hyperglycemia is characterized by an elevated level of glucose in the blood. It is normally asymptomatic, except for an extremely high level, and thus a person can live in that state for years before the negative - sometimes irreversible - health impacts appear. Unexpected hyperglycemia can also be an indication of diabetes, a chronic disease that, when not treated, can lead to serious consequences, including limb amputations and even death. Therefore, identifying hyperglycemic state is important. The most common and direct way to measure a person’s glucose level is by directly assessing it from a blood sample by pricking a …

Expression And Purification Of Snake Antivenom Peptide In Pichia Pastoris, Israel Juarez Contreras Dec 2019

Expression And Purification Of Snake Antivenom Peptide In Pichia Pastoris, Israel Juarez Contreras

Master's Theses

It has been shown that a peptide of the first 10-15 N-terminal amino acids of the lethal toxin neutralizing factor (LTNF) protein found in opossums (Didelphis spp.) holds promise as a low-cost therapy for snake envenomation. To date, the 11-mer has been expressed in E. coli and shown to neutralize snake venoms. However, possible endotoxin concerns warrant an investigation into other microbial hosts. The methylotrophic yeast, Pichia pastoris, shows promise as an alternative host. Active LTNF peptide was expressed and purified in P. pastoris. This was accomplished by subcloning a tandem repeat of the first 15 N-terminal amino acids of …

Factors Affecting Polymer Brush Thermal Stability, Alexis Sarabia Dec 2019

Factors Affecting Polymer Brush Thermal Stability, Alexis Sarabia

Master's Theses

Nanostructures, features that are generated on the scale of 1-100 nm, have potential in many applications including semiconductors and sensors. Mixed polymer brushes, which are composed of two or more unique polymer types covalently tethered to a solid surface, have been shown to give rise to distinct nanostructures. The solid support for these systems can be flat surfaces, such as silicon wafers, or 3-dimensional surfaces, such as nanoparticles. Polymer brushes are mechanically and chemically robust, but their thermal stability is not well understood. Because many potential applications require elevated temperatures, understanding and tuning their thermal stability is important. We studied …

The Deformability Of Red Blood Cells In Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (Me/Cfs), Brendan Robert Schmidt Dec 2019

The Deformability Of Red Blood Cells In Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (Me/Cfs), Brendan Robert Schmidt

Master's Theses

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disease that causes profound fatigue in its sufferers as well as loss of concentration, headaches, and sleep abnormalities. Unfortunately, the disease is poorly diagnosed, and etiology is not known. Although the ME/CFS patients do not show anemic readings, and their arterial partial pressure is normal, it is possible that their extreme post-exertional malaise stems from poor microvascular perfusion and oxygenation. Previous studies have indicated that the red blood cells (RBCs) in ME/CFS patients show evidence of oxidative damage. We hypothesized that the RBC deformability metrics can serve as a reliable biomarker of ME/CFS …

Predicting Switch-Like Behavior In Proteins Using Logistic Regression On Sequence-Based Descriptors, Benjamin Nathan Strauss Dec 2019

Predicting Switch-Like Behavior In Proteins Using Logistic Regression On Sequence-Based Descriptors, Benjamin Nathan Strauss

Master's Theses

Ligands can bind at specific protein locations, inducing conformational changes such as those involving secondary structure. Identifying these possible switches from sequence, including homology, is an important ongoing area of research. We attempt to predict possible secondary structure switches from sequence in proteins using machine learning, specifically a logistic regression approach with 48 N-acetyltransferases as our learning set and 5 sirtuins as our test set. Validated residue binary assignments of 0 (no change in secondary structure) and 1 (change in secondary structure) were determined (DSSP) from 3D X-ray structures for sets of virtually identical chains crystallized under different conditions. Our …
