This particular study focuses on the changes in the ideas and perspectives of Nicaraguan women throughout the span of several generations. With the gaining popularity and successful strides that women have made to advance the Women’s Movement in Nicaragua, the definition of empowerment, the ideology of stereotypes, and the manner...
How do fishing guides of the Cascade and Coast Range rivers negotiate the conflicting tensions between their client’s desire to experience the wild and the extractive nature based tourism of their role as fishing guides? How do they position their services relative to the environment and an imagined landscape that...
What makes invasive species successful, and how do they affect native populations and communities? I addressed these key questions in the context of the invasion of Atlantic coral reefs by Pacific red lionfish (Pterois volitans). To assess the role of parasites in contributing to the success of this invasion, I...
Investigations on the application of self-assembled monolayers (SAM) to indium gallium zinc oxide (IGZO) thin film transistors (TFT) for fabrication and channel modification are presented. The back channel of IGZO thin film transistors can be modified by the absorption of self-assembled monolayers. The electrical properties of the IGZO exposed back...
As species of ash trees become increasingly threatened worldwide by exotic pests and pathogens, it is important to develop descriptions of their ecologies that help guide the conservation and restoration of forests in which they are a major component. Oregon ash (Fraxinus latifolia) is a dominant tree species in wetland...
Invasive plants have the capacity to transform landscapes and alter ecosystem function, causing significant economic and ecological damage. These effects include displacement and reduction of native flora and fauna, altered fire regimes, modification of biotic and abiotic soil properties, as well as local, regional, and global economic impacts. With such...
Translation surfaces can be viewed as polygons with parallel and equal sides identified. An affine homeomorphism φ from a translation surface to itself is called pseudo-Anosov when its derivative is a constant matrix in SL₂(R) whose trace is larger than 2 in absolute value. In this setting, the eigendirections of...
Concrete is the most widely used construction material in the world. When constructing large concrete structures, concrete may have to be placed in multiple lifts. In these cases, fresh concrete is placed on hardened concrete. The interface that is formed between these two lifts of concrete is known as a...
Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...
Historically, the difficulty of obtaining pure cultures of abundant marine
microbial plankton has an obstacle to reconstructing the underlying
mechanisms of biogeochemistry in the ocean. While a number of dominant
marine species from the ocean surface have been cultured, the dominant
microbial plankton of the dark ocean proved far more...
Wine volatile composition is one of the most important constitutes of wine quality, and it is greatly influenced by number of factors. The studies herein were conducted to evaluate the grape and wine aroma affected by different vine nutrient status, vigor and crop levels of Oregon Pinot noir.
In the...
In 2003, due to the dramatic growth of economy, China’s National Development and Reform Commission proposed to build 13 dams on the Nu River to fulfill the nation’s rapidly growing demand for hydropower. The 13 dams that comprise the Nu River Project (NRP) are considered among the biggest hydropower development...
The purpose of this thesis was to understand the relation between the actual performance and the design performance of the manufacturing plane which was designed for the 2016 Design/Build/Fly competition. The actual performance was determined using an Arduino Uno based system with data from an accelerometer, gyroscope and pitot tube....
Since its inception as a laboratory animal in the early 1970s, the zebrafish has proven itself a rising star in the world of comparative biomedical sciences due to its short generation time, ease of care, external fertilization, and transparent larvae. In a very few decades, the zebrafish has been utilized...
Background: The capability of an individual to produce force rapidly is important for performance of sporting activities and to stabilize a joint to protect against injury. Rate of torque development (RTD) and contractile impulse (CI) may be more effective than peak torque in assessing rapid torque production. The relationship between...
Autobiography is usually categorized with essays and other technical writings, and rarely considered creative or artistic literature in the public eye. This project explores the elements of autobiography and two authors who break the barriers of conventional practices to create works that also function as creative and artistic literature. Maya...
Autism Spectrum Disorder (ASD) is described as a developmental disability characterized by impairments in social interaction, communication, and repetitive or restricted movements. It has been shown that as children with ASD age, their cognitive and social skills improve with time, and physical activity has been linked with improving aspects of...
Insoluble surfactants are unique molecules that have the ability to manipulate interfacial properties, becoming useful in numerous applications such as detergents, wetting agents, emulsifiers, foaming agents, dispersants, and more. Interfacial rheology is a field that attempts to characterize the flow properties of insoluble surfactants by exerting a stress on the...
As global population and affluence continues to rise, demand for and disposal of
consumer products is increasing. Currently, there are established process that guide
designers to develop innovative products, but these products still have a large impact
on the environment. There is beginning to be an emphasis on product sustainability,...
High field time-domain terahertz spectroscopy (TDS) is used to determine the time dependent transmission and the time-delay and optical-power dependent conductivity of a wafer of gallium arsenide (GaAs). Gallium arsenide is a direct band-gap semiconductor and has potential as a computer processor component. Analysis of the transmission of terahertz (THz)...
