Comparison Of Biofilm Media In Reciprocating Biofilters Treating Dairy Flushwater, Kyle Keoki Tatsuo Fooks

Master's Theses

Reciprocating biofilters known as ReCip is a viable technology to manage nutrients, mainly nitrogen, problems at livestock operations such as swine farms and dairies. Past studies have demonstrated that ReCip is more adept at total nitrogen (TN) removal than traditional subsurface flow wetland systems. The traditional substrate used to attach biomass was rock aggregate; this media may be hard to obtain for some agricultural projects, so alternate substrates are tested and compared with the rock aggregate. The purpose of the study was twofold: first, different biofilm media were tested and compared in terms of treatment performance and, second, the long-term …

Settling Performance In Wastewater Fed High Rate Algae Ponds, Elliott Blake Ripley

Master's Theses

Although high rate algae ponds (HRAPs) are a proven wastewater treatment technology with numerous environmental, social, and economic benefits, their widespread use has been hindered by inconsistent and unreliable settling performance. Hence, the goal of this thesis is to investigate how specific operational parameters affect the settling performance of HRAPs. Nine HRAPs (30 m² surface area, 0.3 m depth) were operated as three triplicate sets, with each set run on either a 2, 3, or 4 day HRT continuously from January 25, 2012 through April 11, 2013. Settling performance was determined (i) by measuring the TSS of Imhoff cone …

With the Cal Poly UAV FLOC Project, such an infrastructure was created, paving the way for future experimentation with multiple UAV control systems. …

Early Forest Fire Heat Plume Detection Using Neural Network Classification Of Spectral Differences Between Long-Wave And Mid-Wave Infrared Regions, Raul-Alexander Aldama

Master's Theses

It is difficult to capture the early signs of a forest fire at night using current visible-spectrum sensor technology. Infrared (IR) light sensors, on the other hand, can detect heat plumes expelled at the initial stages of a forest fire around the clock. Long-wave IR (LWIR) is commonly referred to as the “thermal infrared” region where thermal emissions are captured without the need of, or reflections from, external radiation sources. Mid‑wave IR (MWIR) bands lie between the “thermal infrared” and “reflected infrared” (i.e. short-wave IR) regions. Both LWIR and MWIR spectral regions are able to detect thermal radiation; however, they …

A Meta-Analysis Of Candidate Gene Association Studies On The Blood Pressure Response To Aerobic Exercise, Michael L. Bruneau Jr

Master's Theses

ABSTRACT

Purpose: Aerobic exercise (AE) lowers blood pressure (BP) 5-7 mmHg among those with hypertension, but there is considerable variability in the BP response to AE. Genetic predispositions account for 40-65% of this variability; however, identifying genetic variants that associate with the BP response to AE is a challenge. We performed a meta-analysis to integrate the small number of studies that examined the influence of candidate genes on the BP response to AE. Methods: Studies retrieved included an acute or chronic AE intervention; BP before and after AE by genotype; and candidate gene polymorphisms. Effect sizes were the standardized mean …

Polyphenol Composition Of Underutilized Aronia Berries And Changes In Aronia Berry Polyphenol Content Through Ripening, Rod Taheri

Master's Theses

Chokeberry (Aronia melanocarpa, Aronia prunifolia, Aronia arbutifolia) is notable for its high phytochemical content, particularly anthocyanins and proanthocyanidins. Aronia berries of different genotypes may vary in their polyphenol content, so it is important to characterize these compounds based on species, and to determine whether or not aronia fruit color correlates with phytochemical content. Using normal-phase HPLC, UPLC-MS, and the DMAC and Folin-Ciocalteu assays, polyphenols in twelve different aronia accessions were quantified and characterized based on fruit color. Significant diversity was observed in anthocyanin content among berries of different colors, with black aronia berries (mean = 10.47 mg/g DW) …

Effects Of Herbivory As An Ecological Constraint Of Willow Growth At A Restored Riparian Corridor, Jacqueline A. Mccrory

Master's Theses

A critical component of nearly all riparian restoration projects is the rapid successful recovery of native vegetation. The dynamic conditions and diverse biotic community supported by riparian ecosystems can present numerous constraints to restoration efforts. This study investigated stunted growth of arroyo willow (Salix lasiolepis) cuttings planted along the banks of Redwood Creek as part of the National Park Service’s Muir Beach Restoration Project to restore habitat for special status species in California. Based on observations of deer browsing, as well as signs of extensive biomass removal, I designed a field experiment using exclusionary fencing to test the significance of …

Utilization Of An Anti-Nnk Recombinant Antibody To Reduce The Harm Associated With Smokeless Tobacco, Heather L. Wanczyk

Master's Theses

Tobacco products, both combustible and smokeless, contain abundant amounts of toxic chemicals and carcinogens capable of causing extensive damage to the body. Tobacco specific nitrosamines, including 4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanone (NNK) and N’-nitrosonornicotine (NNN), are among the most potent of these carcinogens and are capable of eliciting cellular transformations within the body after bioactivation by cytochrome P450 enzymes. In order to reduce the harm associated with smokeless tobacco, a recombinant anti-NNK antibody has been constructed from a hybridoma secreting a mouse monoclonal antibody specific for NNK.

In work performed previously, hybridomas were created by constructing a structurally-related benzoyl derivative …

The Effect Of Skeletal Muscle Mass On Basal Metabolic Rate In College-Age Males 2013, Chase Vaughn

Master's Theses

There are many misconceptions within the fitness community. One such misconception is that an increase in muscle mass will have a large increase in basal metabolic rate, yet this may not be the best way for successful weight loss. The purpose of this study was to determine the strength of the correlation between skeletal muscle mass and basal metabolic rate. The hypothesis tested was that basal metabolic rate is strongly correlated with skeletal muscle mass. The participants were college-aged males (n =17). Skeletal muscle mass (SMM) was estimated using the skin-fold circumference model (SFCM): SMM (kg) = Ht (0.00744 CAG2 …

The Effects Of Angiogenic Growth Factors On Mesenchymal Stem Cell Proliferation And Differentiation To Vascular Cell Fates, William Anthony D'Angelo

Master's Theses

Mesenchymal stem cells (MSCs) are multipotent cells that can differentiate into several cell lineages, including mural cells, which surround and support blood vessels, and possibly endothelial cells, which form the blood vessel walls. In this study, we investigated the effects of basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF), two of the best-characterized angiogenic factors, on MSC proliferation and differentiation. We hypothesized that treatment with these two factors could inhibit mural cell character and promote differentiation toward an endothelial cell fate. C3H/10T1/2 cells (a line of MSCs derived from mouse embryonic tissues) were treated with bFGF and …

Modeling And Analysis Of A Dynamic Voltage Regulator, Timothy David Haskell

Master's Theses

Increased government funding and incentives in recent years has led to an increase in the number of grid-tied renewable energy sources as their economic benefits become more renowned. Unfortunately, the outputs of these renewable resources are often highly variable, resulting in undesirable voltage disruptions that are harmful to sensitive loads. In addition to the energy variability of renewable energy sources, random voltage sags, swells and disruptions are already a major issue in power systems. Recent advances in power electronic devices have provided a platform for new solutions to the voltage support problem in power systems. One promising solution is the …

Comparison Of Stated Iron Concentrations Between Name Brand And Generic Children's Multivitamins, Ashlea Nicole Pettengill

Master's Theses

The mineral iron is one of the most common minerals on Earth; not only is iron found in the atmosphere, water, and plants, it is an essential mineral needed for the human body. Children need iron at a young age to ensure proper growth and development of myelin, to promote oxygen transportation within red blood cells, and to assist in Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). With iron readily available in children's multivitamins, iron toxicity can become an issue when taking too many tablets. With two types of brands, generic and name brand, parents should be aware of the …

Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis

Master's Theses

Anxiety disorders are the most prevalent class of mental disorders, often characterized by a chronic course and comorbid psychopathology. The anxiety-stress literature utilizing cortisol as a biomarker of the hypothalamus pituitary adrenal (HPA) axis has been inconsistent. The establishment of salivary alpha-amylase (sAA) as a biomarker of sympathetic nervous system (SNS) activation allows researchers an opportunity to examine the stress response more fully. This study sought to explore relationships between trait anxiety and salivary stress biomarkers in an outpatient sample attending a specialized anxiety treatment center. Multiple regression and moderator analyses were conducted to examine associations between psychosocial and physiological …

Effects Of Ovariectomy And Anatomical Location On Osteonal Encroachment In Adult Cortical Ovine Bone, Paige Brell Ryan

Master's Theses

The purpose of this study is to further quantify adult ovine ovariectomized bone for new remodeling characteristics to obtain a better understanding of how remodeling is occurring and the effectiveness of this animal model for the study of postmenopausal osteoporosis. Postmenopausal osteoporosis is a major health concern and animal models to test new treatment options are needed. The ovine model is a good option because the ewes undergo Haversian remodeling, are a large sized animal, and have a similar hormone profile to humans. Ewes, however, do not undergo a natural menopause, so an ovariectomy surgery was conducted in the sheep …

Home Range And Habitat Use Of Santa Rosa Island Foxes (Urocyon Littoralis Santarosae), Elizabeth Marie Drake

Master's Theses

Island foxes (Urocyon littoralis) are currently listed as federally endangered on four of the six Channel Islands to which they are endemic. The Santa Rosa Island (SRI) population declined by 99% during the 1990’s due to non-native golden eagle (Aguila chrysaetos) predation and is currently the lowest fox population (~280) and density (0.86 foxes/km²) of any of the Channel Islands. The goals of this study were to assess new miniaturized GPS technology and to quantify home range and habitat use of the SRI population. This is only the second use of Global Positioning System (GPS) …

Effects Of Damage Arrestment Devices On The Fatigue Life Of Impacted Composite Sandwich Beams, Yvette Vanessa Wood

Master's Theses

The use of composite sandwich panels is rapidly increasing in the aerospace industry. In these applications, thin composite face sheets are typically co-cured to foam or honeycomb cores. One of the greatest concerns in these types of applications is face-core delamination because it can ultimately lead to catastrophic failure of the structure. Further, the effects of foreign object damage on composite sandwich structures are often catastrophic. Damage to the structure is often undetectable through visual inspection, leading to concerns of unknown interlaminar damage through the life of the structure, which can cause a catastrophic failure. This research determines the effectiveness …
