Modeling friction stir welding of Al 2024-T3 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Friction stir welding (FSW) is a modification of the traditional friction welding. It is a process patented by The Welding Institute in Cambridge, England in 1991. It is a mechanical process whereby solid-state welding ...
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 ...
Efficacy of modified constraint-induced movement therapy (mCIMT) protocol with clients with chronic stroke [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Objective: To determine efficacy of a new modified constraint - induced movement therapy protocol in clients with chronic stroke. Method: Each participant will undergo a six week modified constraint-induced movement (mCIMT) ...
Natural variation in phenotypes associated with phototropins among geographically isolated populations of Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In Arabidopsis thaliana several phenotypes are controlled by blue light including chloroplast relocation movements and bending of the seedling stem in phototropism. These responses are controlled by the phototropins, phot1 ...
Electrohydrodynamic conduction pump - An experimental investigation [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Electrohydrodynamic pumps (EHD) were built and tested to further understand the nature of the technology. Two pumps built used a conductive pumping action to achieve flow within a dielectric fluid. The first pump (pump 11) ...
Identification of chloroplast DNA insertions in nuclear chromosomes of maize B73 line using the FISH procedure
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
It is known that chloroplast DNA can incorporate itself into the nuclear genome of plants. However, the sites of chloroplast (ct) DNA integration into chromosomes of maize have not yet been analyzed. This project is the ...
The effects of oncogenic Ras on the ocular lens
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Ras is a small GTP-binding protein in the signal transduction machinery. In most cell types, activation of Ras by growth factors is essential for normal cell proliferation. A mutation in the Ras gene can lead to a constitutive ...
Production of nano particles
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Nano particles (particles having diameters in the nanometer range) have applications in a variety of areas including medical, environmental, sensor, to name a few. However, the production of nano particles having uniform ...
The psychosocial response to lymphedema
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Lymphedema, a life-altering disease, affects many breast cancer survivors throughout the world. Manifested as either an acute or chronic illness, lymphedema can occur at any time during and following post-breast cancer ...
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 ...
Point mutation of an RGD sequence in the human P2Y2 receptor to a QGD sequence conserves Go-mediated signal transduction
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The P2Y2 nucleotide receptor is a Go/q coupled receptor that is activated equipotently by extracellular nucleotides such as ATP or UTP and is upregulated in a variety of tissues in response to injury or stress. The biological ...
Detection of Sad genes in various species of Neurospora
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Neurospora crassa is a haploid fungus that reproduces asexually during vegetative growth. However, in a nitrogen deficient environment, the two mating-type cells, A and a, can fuse together and enter the sexual cycle. ...
Analyzing the effects of lactose on calcium absorption in premature infants using HR-ICP-Mass Spectrometry
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
With advances in neonatal care, premature infants are surviving at increasing rates. During the third trimester of pregnancy, the bone mineral content of infants rapidly increases. It is therefore becoming essential to ...
Evidence that glutamate induced neurite retraction of reticulospinal neurons is dependent on calcium influx
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Locomotor systems of vertebrates consist of a command system in the brain that activates central pattern generators in the spinal cord to initiate locomotor behavior. Reticulospinal (RS) neurons are the output neural ...
The correlation between Chicano theater and Augusto Boal's Theater of the Oppressed
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
"The theater is a weapon, and it is the people who should wield it" are words that come from the Brazilian Dramatist's, Augusto Boal, commentary, The Theater of the Oppressed. What Boal is referring to is that the theater ...
Rapid automated characterization of transposon insertion mutants in Desulfovibrio vulgaris Hildenborough by srnPCR [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Tn5 transposon mutagenesis occurs by a mechanism in which a segment of DNA (transposon) encoded in a plasmid is inserted into genomic DNA (the target) by a conservative (cut-and-paste) mechanism (Fig. 2). When the insertion ...
Photoacoustic detection of circulating melanoma cells in the plasma layer of the blood [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
When a melanoma patient is diagnosed, aggressive treatment is advised in an effort to contain the disease. Although the initial malignant cells are destroyed, it is impossible to determine whether or not the cancer has ...
