Bat avoidance behavior in Neoconocephalus retusus (Orthoptera: Tettigoniidae) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Nocturnally flying insects avoid predation by insectivorous bats by monitoring for echolocation calls and, when detected, using evasive behaviors. We examined the responses of Neoconocephalus retusus to models of bat calls ...
Identification of QTL associated with root architecture under well-watered, and water-stressed conditions in Zea mays [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Drought alone contributes 17% to the average annual yield loss in maize (Zea mays). It is the single most significant environmental obstacle to improving grain yield. Many physiological traits have been linked to drought ...
Genetic mapping of a chromatin-level modifier [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
In many organisms, gene activity can be regulated by packaging of the DNA into chromatin. In general, loose chromatin structure is associated with transcriptionally active genes, while inactive genes have tighter chromatin ...
Enzymatic analysis of matrix metalloproteinases using heterotrimeric and homotrimeric type I collagen as a substrate [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The goals of this study are to determine if specific MMPs differentially degrade heterotrimeric and homotrimeric type I collagen, and the role of MMPs in the oim collagen glomerulopathy. Type I collagen is typically ...
Near-optimal launch guidance using energy-angular momentum relationship [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The nonlinear dynamic equations for launch vehicles make the optimal control solution difficult to obtain. These solutions have multiple parameters (i.e. Lagrange multipliers) for which the proper initial values must be ...
A study of the quality and value improvements of Show-Me-Select heifers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Missouri's largest source of agriculture revenue, the forage-based beef cattle industry, could become a bigger player in the state's total agriculture revenue and on-farm income with some industry modifications. As a result, ...
Identifying out of context smiling in children: Are they really happy? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
We examined children's expressions characteristic of smiles during pleasurable (in context) and distressing (out of context) situations. We hypothesize that smiles during distressing contexts were not accompanied by pleasure. ...
Going underground: Benefits of phototropism in Arabidopsis depend on the soil environment [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Phototropins are blue-light photoreceptors that control shoot and root phototropism in
Arabidopsis thaliana. We investigated whether the soil environment influences the benefit of
phototropism. We hypothesized that root ...
The role of language in the expression of shyness [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research., 2004)
Abstract of a presentation presented at the Undergraduate Research Conference 2004. Presentation reported on a study designed to analyze the relationship between verbal and non-verbal communication and shyness in twenty-four ...
The synthesis of adenine in interstellar space [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Found in both DNA and RNA, adenine is one of the most important biological molecules. As critical as it is, though, adenine is simply a pentamer of hydrogen cyanide. It could possibly be synthesized in space from naturally ...
Evaluation of Saint Louis Motorist Assist Program [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
My research evaluated the safety and efficiency impacts of the St. Louis Motorist Assist, a program of the Missouri Department of Transportation. The program's purpose is to improve freeway safety and expedite the flow of ...
Marketing research: Assisting decisions of the MU Career Center [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
This project takes a look at marketing research conducted for the MU Career Center located in Lowry Mall. Prior to the winter semester of 2004, little was known about the effectiveness of various advertising mediums utilized ...
Perceptions of effective and ineffective professional development held by teachers and staff developers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Our research is focused on the effectiveness of professional development for science and mathematics teachers in Missouri. Professional development is a term used to describe experiences which are aimed to improve teacher ...
Steel stud wall systems for blast protection [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Steel stud walls are very common in commercial and military construction. These walls are normally designed to resist wind loads, and to some extent, seismic loads. The walls are currently designed to resist a uniform ...
Methodology for interference analysis using electromagnetic topology techniques [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The project focuses on the effects of electromagnetic pulses on shielded and unshielded electronics in various applications, from pacemakers to guidance systems in airplanes. The research is mostly simulation based. In the ...
Fuel efficiency of No. 2 diesel fuel vs. a 5% biodiesel, 95% diesel blend [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The project shall consist of comparing the efficiency of a 1990 model 14.1 litre Cummins diesel engine comparing standard no. 2 diesel fuel to a 5% biodiesel blend.
Age dependent increase in UVA-induced bleaching of the brown components of the human lens [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
With age, human lenses accumulate a yellow color. This yellow color is a risk-marker and possibly riskfactor
to the formation of cataracts. The yellow color, that is accumulated, is at its highest
concentration in the ...
