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 ...
Characterizing the role of Glycine max NHL gene family members in plant-nematode interactions [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Soybean cyst nematode (SCN; Heterodera glycines) is a microscopic parasitic roundworm of soybean that causes nearly $1 billion dollars in annual yield loss in the United States. SCN damages the plant by attaching itself ...
Protecting biodiversity: Riparian buffers directly affect Appalachian headwater salamanders [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Salamanders are the most abundant invertebrate predator in the southern Appalachians; they have the highest biomass, and they are an important species for scientific investigators. Their permeable skin and eggs makes them ...
Developing a nowcasting technique for splitting supercells by analyzing rapid update cycle model data [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The goal of this research project was to develop a nowcasting technique, or to at least find out which parameters are changed to help supercells split. This was first completed by overlaying Rapid Update Cycle (RUC) model ...
The construction of neoliberalism and its effect on Mexican water policy [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
After the debt crisis of 1982, Mexico began implementing neoliberal policy, which culminated in the ratification of the North American Free Trade Agreement (NAFTA). The neoliberal reforms fundamentally changed environmental ...
The effectiveness of blended learning environments for the delivery of respiratory care education [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
It has been reported that the major weakness of online learning environments is the lack of consistent, efficient communication with the course instructor. In an attempt to provide the learner with the “best of both worlds,” ...
Cuando los Negros Luchaban (the Black Struggle): 1965 U.S. invasion of the Dominican Republic [abstract]

On April 22, 1965, in Santo Domingo, the Dominican Republic, left winged military men launched a coup against the U.S. backed president in order to restore the presidency of Juan Bosch, a proclaimed populist whom the United ...
Efficacy of curcumin in ameliorating the toxic effects of ochratoxin A and aflatoxin in young broilers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Two experiments (hatch to 21 days) were conducted to evaluate the efficacy of curcumin to ameliorate the toxic effects of aflatoxin (AF; Exp.1) and ochratoxin A (OA; Exp. 2). Food grade turmeric powder (Curcuma longa) ...
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 ...
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 ...
Effects of early intervention targeting mathematically at-risk first grade students [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In the 2006-2007 school year, 7.3 percent of third grade students scored in the lowest percentile in mathematics on the Missouri Assessment Program test. This percentage increased as students progressed through school. In ...
Population trends of forest birds in Missouri, USA: Comparison of point count data with predictions from the BBS [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Long-term population size trends of Neotropical migrants and other forest birds are of primary concern for conservation biologists. The Breeding Bird Survey (BBS) has become an important tool for biologists in estimating ...
The role of the brassinosteroid associated kinase (BAK1) in plant cell defense [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Plants are able to resist bacterial and fungal infection by recognizing invading organisms outside the cell and then activating defense responses inside the cell. The first line of defense against invading organisms is ...
An estrogen induced, estrogen responsive rat model of breast cancer [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Because women experience a bewildering array of chemicals, foods and lifestyles, only profound effects on preventing or promoting breast cancer are detectible in human studies. Subtle or delayed effects can be detected in ...
Composing a biocomposite mesh for hernia repair [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Hernias are formed when the tough connective tissue that surrounds the abdominal musculature, known as fascia, breaks down, weakens, or actually rips [1]. As a result, there is a bulging of the intra-abdominal viscera ...
