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 ...
Efficacy of a modified constraint induced movement therapy protocol in the clinical setting [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Constraint induced movement therapy (CIT) is an intervention strategy used by rehabilitation therapists for people who have experienced stroke. Traditional CIT protocols require participants to wear a restraint on their ...
Generating Gbx2 antibodies: A useful tool in determining developmental mechanisms regulated by GBX2 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The GBX class of homeobox genes is comprised of Gbx1 and Gbx2. Both loss-of-function and gain-of-function studies in mice have shown that Gbx2 is vital for normal anterior hindbrain development of mammalian organisms. To ...
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 ...
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 ...
Regulation of menaquinone production in Desulfovibrio vulgaris Hildenborough and Desulfovibrio desulfuricans strain G20 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Menaquinones are cytoplasmic membrane components that have important roles in electron transport for energy generation in anaerobic bacteria. A simple and sensitive protocol for the purification and quantification of ...
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 ...
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 ...
Electric arc production of nanoparticles for energetic materials [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Thermites are a class of energetic material (similar to explosives) which consists of a fuel and oxidizer which react chemically to release energy. These materials are of interest because they can contain over 2.5 times ...
The role of gender in the peer review process of formal writing [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Traditionally, the assessment of student work has been the primary responsibility of a teacher or professor. However, the process of peer-review has truly taken hold in recent times as a method for others objectively ...
Carbon nanotubes and their composites with nanodiamond for thermal packaging: Syntheses, characterization and modeling [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In the family of carbon-based nanosystems, carbon nanotubes (both single- and multi-walled) are cylindrical carbon molecules with many extremely useful properties that make them ideal for use in multitude of technological ...
Role of Cyclooxygenase-1 during the immunological response in lyme arthritis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Previously, pharmacological inhibition of COX-1 in wild-type C3H mice resulted in changes in antibody production in response to infection with the causative agent of Lyme Disease, the spirochete Borrelia burgdorferi (Bb). ...
Roach colony optimization: a new approach to problem solving [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Computational intelligence, more specifically agent-based computing is a new way of thinking about computation that differs from the old methods of logical deconstruction and processing. We are developing a computational ...
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 ...
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. ...
Empowerment through journalism: social change through youth media production in northeast Brazil [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
