Spermatid specific thioredoxin (SPTRX3) as a novel human male infertility marker [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Spermatid Specific Thioredoxin (SPTRX3) is a protein that accumulates in the superfluous cytoplasm of defective human spermatozoa. We researched the relationship between SPTRX3 and male infertility in men from 239 couples ...
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 ...
Development of optical models for non-invasive glucose testing [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Current blood glucose measurement techniques are invasive and uncomfortable. Developing a non-invasive technique will not only alleviate part of the pain involved with current techniques but also cost less, greatly benefiting ...
How the position of menu items on a one-page menu effects item popularity [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The subject of this research project was to determine if the menu position of an item influences the number of times it is ordered. In this particular study, one-page menus were examined. A new menu was designed where each ...
An empirical analysis of the underlying premises of the [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Over the past 30 years, there has been a debate in courts and academia over whether federalism is better protected by judicial or political safeguards. In Garcia v. SAMTA (1985), the Supreme Court ruled that it would not ...
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 ...
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 ...
A multicopy suppressor screen in yeast to look for negative regulators of Ser13 phosphorylation-based trafficking to the pre-vacuolar compartment
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Resident membrane proteins of the yeast trans-Golgi network (TGN) frequently cycle between the TGN and both the early and late (prevacuolar) endosomal compartments. The model yeast TGN protein, A-ALP, which contains the ...
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. ...
Effects of exercise on bone parameters in the oim mouse model [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Previous studies have shown that mechanical loading on the skeleton acts as an anabolic stimulus, including changes in bone geometry, bone mineral density, and mechanical properties. Increases in these properties may improve ...
Domain specific interaction of S-RNase binding protein with the stylar 120 kDA glycoprotein in nicotiana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Through the process of evolution, many flowering plants have developed a biochemical mechanism to prevent self-pollination and pollination by closely related plants. Gametophytic self-incompatibility (SI) is one such system ...
Producing practical uses for biodiesel byproducts through the conversion of glycerol [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
With biofuels such as biodiesel and ethanol becoming increasingly popular alternatives to fossil fuels in our society, the question becomes one of economics. The production technologies are quickly becoming available, but ...
Factors affecting long-term counts of drumming ruffed grouse in Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Ruffed grouse were nearly extirpated in Missouri during the early 1900's because of habitat loss but several populations were re-established by reintroductions. The number of drumming-male grouse has been surveyed on the ...
Do young children recognize the sound system of their native language? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Children must learn the phonological rules of their language (what sounds are allowable). For example, a word cannot begin with [zw] in English, but it can in German (e.g., zwiebel). English-speaking adults all know that ...
