Establishing the status of the American black bear in southern Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The current status of the black bear population in Missouri is largely unknown, as we have little to no information concerning its size, reproductive status and origin. However, evidence suggests that the bear population ...
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 ...
MCP-1 and its role in lyme arthritis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Lyme disease is caused by infection with the bacteria Borrelia burgdorferi, causing arthritis and carditis in infected animal models. The presence of spirochetes in the joint and other soft tissues induce recruitment of ...
Dengue RdRp characterization [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Dengue virus kills 25,000 people annually in affected tropical regions. Non-structural protein 5 of the virus has RNA-dependent-RNA-polymerase and methyltransferase activity in separate domains. Since genome duplication ...
A comparative study of the feral horses of Shackleford Banks and Assateague Island [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Feral horses (Equus caballus) can be found today in isolated barrier island populations along the eastern coast of the United States. Assateague Island stretches for 37 miles along the coasts of Maryland and Virginia and ...
Cerebellar white matter abnormalities in phenylketonuria (PKU) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Phenylketonuria (PKU) is a recessive genetic disorder that is characterized by an individual's body being unable to utilize the amino acid phenylalanine because of a dysfunction with the enzyme phenylalanine hydroxylase. ...
Pathogen susceptibility to Pseudomonas syringae in Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Peptides may act as regulatory molecules that coordinate cellular responses needed for growth, differentiation and development. A novel family of small peptides, encoded by the DEVIL (DVL) gene family, was identified in a ...
Differential effects of the components of higher education expenditure on U.S. state economic growth [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
externalities as was previously expected. On one hand, some scholars argue that greater public funding on education is needed to increase labor force productivity. On the other hand, research indicates that the cost of human capital investment has increased...
Photolytically-controlled release of dexamethasone [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
photolytically labile molecule. Prior to this, we characterized the diffusion of dex within our hydrogel network. Our experiments demonstrated that we could achieve controlled release of dex wih varying light intensity and it should thus be possible to achieve...
Resolution of phylogenetic patterns within the angiosperm order Asparagales [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The angiosperm order Asparagales, is an economically important monocot order that includes onions (Allium), asparagus (Asparagus), and agaves (Agave). The core Asparagales includes ten families that form a monophyletic ...
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 ...
Evaluating the relationship between leaf nitrogen concentration and Minolta SPAD-502 meter readings [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Oak trees are deciduous trees that can live for up to 200 years and face a variety of environmental stresses. Like all plants, oak trees need nutrients, which vary under different stress conditions. We study nitrogen as ...
Assessing the value of agricultural streams as amphibian refuges [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Although many causes for worldwide amphibian population declines are under investigation, the destruction and alteration of aquatic habitats remains a primary threat. In agricultural landscapes, natural wetlands are often ...
The influence of increased contact rate among raccoons on a nematode of public, and wildlife health concern, Baylisascar [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Natural and anthropogenic fluctuations in resource availability can alter the behavioral ecology and population dynamics of wildlife. This may have unintended consequences to wildlife disease ecology, as theoretical models ...
Vegetation classification in urban nature areas in Columbia, Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Urban nature areas are often identified by local governments with no thought to their ecological characteristics or conservation value. We used a vegetation classification procedure, entitation, to classify vegetation types ...
The manifestation of death in Nathaniel Hawthorne's gothic fiction [abstract]
