The key to unlock the Navier-Stokes Equation
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The key to unlock the Navier-Stokes Equation What causes the waves to break, as they get closer to the shore? Can the strain on the heart to pump blood throughout our bodies be decreased if vortices were eliminated? When ...
Fescue toxicosis affects the reproduction and thermoregulatory systems of male rats exposed to heat stress
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tall fescue (Festuca arundinacia), a cool season forage grass, has been utilized by many farmers for over fifty year to feed livestock. Unfortunately, about half of fescue pastures are infected with an endophytic fungus ...
Cell-matrix interaction in tissue patterning
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
In vivo pattern formation during morphogenesis is dependent upon the migration of cells. Cell movements are directed by the local structure of the surrounding extracellular matrix. It has been shown experimentally that ...
Benefits of soy-based feeds for fetal estrogen levels and obesity in adulthood
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
We examined the effect of maternal exposure to naturally occurring estrogenic chemicals in diets on circulating levels of estradiol in mouse fetuses. An animal's specific response to estrogen can vary according to the time ...
A case study of colliding tornadic storms
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tornadoes occur frequently across the United States each year, causing millions of dollars in damage. Meteorologists are constantly searching for new and improved methods for predicting these weather phenomenons's in order ...
Investigation of type I collagen deposition in the glomeruli of COL1A2 deficient mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Type I collagen is the most abundant structural protein in the body, playing a major role in the strength and integrity of connective tissues. Alterations in the synthesis and structure of type I collagen result in a number ...
Involvement of TolC protein in the export of siderophore enterobactin in Escherichia coli
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
To acquire the necessary iron against harsh competition in the environment, iron starved bacteria synthesize, excrete and retrieve iron scavenging molecules termed siderophores, one of which is enterobactin. TolC protein ...
Kinetics vs. equilibrium binding: Determining the mechanism of transcriptional activation of Polymerase II
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The mechanism of transcriptional activation of Polymerase II (Pol II) can be studied in a unique way by using a model transcriptional activator, TFIIIA-VP16, whose DNA-binding domain is derived from the zinc finger protein ...
A study of wireless sensor networks with focus on node localization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Due to research in low-power, cheap wireless communications, Wireless Sensor Networks (WSN) has become one of the most exciting new fields of interest within computer science and engineering. Just as the Internet has made ...
Automatic controllers: Stability and performance in clinical anesthesia
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Anesthesiologists manually control the rate of drug infusion to maintain a desired conscious level (BIS index) for a patient during surgery. With new technological advances, Control Engineers now can automate this drug ...
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 ...
Corolla length and autogamy in Nicotiana
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Nicotiana has been an interest of study due to its variance in autogamy and floral traits. Species N. plumbaginifolia and N. longiflora are characterized by their difference in flower size and the ability to self pollinate. ...
Modern day Jezebels: Racialized sexuality and the images of black women in contemporary hip-hop videos
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Hip-hop music emerged in the 1970's as a countercultural strategy to deter inner city youth from the influence of violence and gangs; it was a form of social expression. The dominant images in early hip-hop music videos ...
Expression of aT4g27260/GH3-5/GH3a studied with in situ hybridization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tropisms, the responses of plants to external stimuli, have been studied as important evolutionary adaptations and as possible areas of future advantageous genetic manipulation. The goal of our current research is to ...
Mitochondrial DNA insertion into nuclear chromosomes of maize
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Every mitochondrion contains its own DNA separate from the nucleus. Over evolutionary time, most of the mitochondrial genes have moved to the nucleus so that now mitochondria require nuclear DNA to function. This type of ...
Improving mouse-DMH screening capability by adding 2000 mouse CpG islands
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
DNA methylation alteration, in correlation with gene expression, is involved in development and progression of many cancers. Using a microarray based method, mouse-DMH (Differential Methylation Hybridization), our lab is ...
Silencing of three members of the cytochrome p450 family of genes to uncover their role in iron regulation in A. thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Iron absorption and distribution by an organism needs to be tightly regulated because iron is essential but in excess it can be dangerous and may even result in death. Through microarray analyses of iron-starved Arabidopsis ...
