Student involvement in clubs and organizations related to undergraduate field of study [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
with no direct congruency to a student's undergraduate degree flourish with membership. Why do students choose not to join departmental clubs or organizations that correspond with their major? A three part Delphi study was conducted to identify what factors...
The construction of neoliberalism and its effect on Mexican water policy [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
of ecological data, policy implementation chronologies, Mexican newspaper reports, and social research on actors provided a multi-disciplinary approach to analyze governance. The research indicates that the construction of power and discourses of neoliberalism...
Prediction of superhelical proteins using machine learning methods [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The main objective is to use three state of the art machine learning methods to find the most efficient way for predicting and characterizing the superhelical proteins based solely on their sequence information. To achieve this goal we will first...
Thrust measurements of a ferroelectric plasma source [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Ferroelectric thrusters can be used in applications where small thrusts are useful such as guiding the movement of satellites. The Pulsed Power and Plasma Science group in the Electrical and Computer Engineering department at MU is characterizing a...
Analysis of hydroxyapatite nanofiber growth [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
-long nanofibers with uniform lengths must be developed. The goal of this research was to determine the nucleation and growth rates of hydroxyapatite nanofibers and use this information to design a process to control the length of the crystals. The methods used...
The formation of cysteine-tyrosine crosslinks via a sulfenic acid intermediate [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Cysteine residues in proteins are readily oxidized to sulfenic acids. Sulfenic acids, in turn, can act as potent electrophiles that have been observed to form intrastrand protein crosslinks with neighboring amide or cysteine ...
Plasma surface modification of silica particles for the increased strength of dental composites [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Many of the problems that exist today with current dental restoration materials can be eliminated through the use of nanofiber fillers such as hydroxyapatite. Materials like this can ultimately provide greater strengths ...
Force feedback control of a hydraulic cylinder [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The objective of this thesis is to demonstrate improvements in the response of a physical hydraulic system when using closed-loop control. A hydraulic system consisting of a power supply, accumulator, and linear actuator ...
Photoacoustic detection of metastatic melanoma in lymph nodes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The project's objective is to detect metastatic melanoma cells in lymph node cross sections using a pulsed laser to generate the photoacoustic effect. When melanoma metastasizes it uses the blood stream or the lymphatic ...
Media lynching on the campaign trail [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
This is a multidisciplinary research project that is about the use of race in political ads from 1988 to 2006. Although the student researcher has analyzed five political ads, only one of the ads, “The Willie Horton” ad, will be discussed...
Effects of temperature on biodiesel supplemented with pork and beef fat compared to standard fuels [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Bio based blends were prepared with pork and beef fat, as well as ethanol on a volume per volume basis. These percentages were determined using previous research. Blends were then tested on temperature characteristics set forth by ASTM standard...
An opportunity for small scale soybean processing [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Missouri is the 6th largest soybean producing state according the USDA, producing 194.18 million bushels in 2006. US soybean production in 2006 approached nearly 3 billion bushels. As the US soybean production increases, ...
Parent-adolescent relationships, sibling ordinal status, and adolescent adjustment [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Investigating the possible moderating affects of sibling ordinal status, researchers tested how differences in parent-child communication and trust between first-born and later-born children influence adolescent depressed mood and problem behavior...
Linearity testing of LED transmitter and corresponding voltage to current op-amp configuration [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The LM7171 operational amplifier is made for high electrostatic discharge and fast signal performance. In a configuration using the diode in the transmitter and a resistor on the negative op-amp terminal, the op amp will ...
Impact of effective instruction within middle school classrooms on at-risk student problem behavior [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Teachers are increasingly faced with students who present challenging behavior in the classroom. When faced with such challenges, educators look for effective ways to manage problem behaviors, as well as to prevent problems, ...
Processing brainwaves for hand-free control of devices [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
We have built a system to observe and analyze brainwaves for use in controlling devices such as wheelchairs and electronic prosthetics bypassing a need for the user to have use of their hands and/or other limbs. The system ...
Development of a RF Class E amplifier to power a ferroelectric plasma thruster [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Class E amplifiers are a special class of electronic amplifiers which are highly efficient at delivering power at high frequencies. Class E amplifiers consist of a signal generator, switch, and two LC resonant circuits. ...
Analysis of genetic drift within the highly repetitive KSP repeat domain and neurofilament medium [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Axonal diameter is one key component utilized to determine conduction velocity. However, the mechanism that influences axonal diameter must be stable within a given species, but flexible enough to adjust to the evolution ...
