Are age-related differences in associative memory mediated by sensory decline? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Naveh-Benjamin (2000) suggested an associative deficit hypothesis, explaining that some of the decline in episodic memory in older adults is due to their difficulty in binding unrelated components together into a cohesive ...
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 ...
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 ...
Stem cells transplanted into the brain are immunogenic and are actively rejected by the host [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Stem cell-based therapies have shown great promise in the treatment of neurodegenerative diseases such as Batten's Disease and Parkinson's Disease. Intracranial stem cell transplantation has the potential to restore function ...
A novel algorithm for semiautomatic brain structure segmentation from MRI [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
On a daily basis, numerous medical institutions use MRI segmentation to conduct research and treat patients. While there are many different segmentation algorithms that exist today, most have drawbacks in respect to either ...
Fourier transforms applied to a hydraulic system [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Control valves (i.e. poppet valves) are commonly used in hydraulic systems for accurate control of the system response. These valves can only provide accurate responses for a limited frequency range. The bode plot is a ...
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, ...
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 ...
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 ...
The key to unlock the Navier-Stokes Equation
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The key to unlock the Navier-Stokes Equation What causes the waves to break, as they get closer to the shore? Can the strain on the heart to pump blood throughout our bodies be decreased if vortices were eliminated? When ...
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 ...
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 ...
Therapy of experimental allergic encephalomyelitis under circumstances relevant to human multiple sclerosis
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Experimental allergic encephalomyelitis (EAE) is an inflammatory disease of the central nervous system (CNS) that resembles human multiple sclerosis (MS). EAE and MS develop when proteins of the myelin sheath that covers ...
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 ...
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 ...
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 ...
Functional analysis of conserved amino acid residues in the C-terminus of ACC synthase
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Ethylene is an important plant hormone that regulates growth, development, and stress response. Synthesis of Ethylene from its immediate precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), is catalyzed by ACC oxidase. ...
The effect of reduced chromatin gene expression on an epigenetically regulated maize gene
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In virtually all eukaryotic organisms, not just plants, genes are regulated at the level of chromatin. In a genomics approach to understand how expression of a gene can be regulated by its chromatin configuration, a series ...
