Design and testing of heat pipes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
tube, the second style utilized end caps, while the third method used a lathe to close the ends of the pipe. Extensive testing was completed on the heat pipes and the pipes were analyzed to determine what effect the various capillary wicks had...
Force feedback control of a hydraulic cylinder [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
. To experimentally measure the response, a load sensor is attached to the linear actuator in series and an extension cylinder and mounting plate ensure the test setup remains stationary. Due to the nature and frequency of applied forces, fatigue failure analysis...
Expression, purification and initial characterization of Halobacterium proline dehydrogenase
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
apoptosis. Despite their importance in human health and disease, these enzymes have not been extensively studied. Thus, the goal of this research is to characterize the structure and function of PRODH. The work presented here focuses on a newly discovered...
Estrogen receptors in TRAMP C2 cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
similar to the type experienced by humans. Similar to humans, in TRAMP mice there are different stages of prostate cancer; well differentiated carcinoma (WDC) and poorly differentiated carcinoma (PDC) are the stages being we study extensively. It has been...
Characterization of the mechanism of action of the ultra-potent HIV inhibitor 4'-Ethynyl-2-Fluoro-2'-Deoxyadenosine [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
the mechanism of RT inhibiton by 4'-E-2-F dA. In order to determine its mechanism of action, in vitro primer extension assays as well as gel mobility shift assays were used. Using primer extension assays, we determined that the active form of 4'-E-2-F dA, 4'-E-2...
Target test tube assembly process and design for the development of molybdenum-99 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
of the swaged tubes. This feature also assists in maintenance and the removal of jammed parts. Using an electron microscope, a gap between the swaged tubes was found using the current punch design. After extensive calculations, a new punch was designed...
A case study of colliding tornadic storms
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
awareness and warning times. In this case study, one event was found in which two storm cells collided and produced a tornado over the Kansas City, Missouri area, causing an extensive amount of damage. The goals of this study is to first determine what...
Maize brace root formation and correlation with juvenile nodes and tassel structure [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
are tolerant to water-stress conditions. A significant trait in drought tolerance is an extensive root system. Root systems in maize are composed of not only below ground roots but also above ground roots. These above ground roots are commonly known as brace...
An in vitro binding assay to identify amino acid residues in Ste13p necessary for Ste13p/Amp1p interaction [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
. Mutant derivatives of Ste13-GST will be tested in the same fashion. Through analysis of the different mutants, we will be able to determine which amino acids are critical for this association, and by extension, critical for Ste13p retrieval from the EE...
Agarose entrapped gold nanoparticles for the crosslinking of collagen: A comparison study [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
influence cellular adhesion and proliferation. Many of these techniques have been researched extensively; however, there is a lack of significant research in the area of nanomaterials and their potential to crosslink collagen. The purpose...
Effectiveness of therapeutic Salmonella Typhimurium in selectively targeting human cancer cell lines [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
at Columbia's Cancer Research Center developed a therapeutic strain, CRC2636, an archival strain of S. typhimurium that has been shown to destroy PC-3M without extensive lysis of the cancer cells, a factor thought to contribute to the toxicity of VNP20009. Our...
Effect of experimental forest treatments on gray treefrog (Hyla versicolor) habitat use [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
accessibility to uncut forests. The effect of extensive clearcutting on amphibians however would likely be detrimental and effects would depend upon a species' life history needs....

of the swaged tubes. This feature also assists in maintenance and the removal of jammed parts. Using an electron microscope, a gap between the swaged tubes was found using the current punch design. After extensive calculations, a new punch was designed...
Rapid automated characterization of transposon insertion mutants in Desulfovibrio vulgaris Hildenborough by srnPCR [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
: frequency and location of priming sites, reaction volume, and reaction conditions (annealing temperature, extension time, etc.). By varying these factors, we have developed an efficient and reliable method for characterizing transposon insertion mutants...
Identifying Lepidopteran resistance within hcf mutants
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Southwestern corn borer (SWCB) and fall armyworm (FAW) feeding on maize causes extensive crop damage in the United States. Previous proteomic analysis comparing resistant and susceptible lines of maize indicates genes found in the photosystem II...
Development of a cell culture model for studying neuronal migration [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Motor neuron migration has been extensively studied in mouse and zebrafish, and is dependent upon the functions of a subset of proteins (Vangl2, Prickle1, and Celsr1) that act in the Wnt signaling pathway. However, other proteins (TAG-1, Laminin α 1...
The effects of even-aged cutting on density and pairing success of Worm-eating Warblers
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
It is important for researchers to be aware of how timber management practices affect songbird populations. Certain forest management techniques can cause declines in breeding habitat of Neotropical migrant songbirds that ...
