An analysis of wireless security in Columbia, MO [Harper - abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The current state of wireless security in most areas can be estimated based on trends and collected data, but the complete picture is often unknown. Without collecting the information on most wireless access points in a ...
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)
Retroviruses rely on the enzyme reverse transcriptase (RT) to perform the reverse transcription of its genome from single-stranded RNA into double-stranded DNA, which can then be integrated into the host's genome by the ...
Expression and proteolytic cleavage of Lav, a putative virulence autotransporter of nontypeable Haemophilus influenzae [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Haemophilus influenzae, a gram negative coccobacillus, is part of the normal flora of the human upper respiratory tract. Unencapsulated (nontypeable) strains of H. influenzae (NTHi) cause pneumonia, sinusitis, and otitis ...
Target test tube assembly process and design for the development of molybdenum-99 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Molybdenum-99 (Mo-99) is used to create Tc-99, a widely used nuclear medicine diagnostic imaging radioisotope. In an attempt to decrease the need for imported Mo-99, development of mechanical systems to efficiently prepare ...
Using Fluorescence in situ hybridization to study maize lines genetically predicted to have chromosomal abnormalities [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Since the 1960s, genetic evidence has indicated chromosome damage and nondisjunction in lines of maize containing knob heterochromatin-bearing chromosomes and at least two B chromosomes. However, at that time researchers ...
Evaluation of a ferroelectric cathode for use in electric propulsion [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Electric propulsion is used to keep communication satellites in the proper position relative to Earth and for propulsion on deep space probes. One part of the propulsion system, the cathode, is required for the neutralization ...
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 ...
Effects of diet and exercise on carotid lesions in male pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The objective of this study was to examine the influence of aerobic exercise-training on atherosclerotic lesion appearance and composition in the carotid artery of male, miniature Yucatan pigs fed a high-fat, high-cholesterol ...
Differential effects of the components of higher education expenditure on U.S. state economic growth [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Over the past thirty years, the importance of human capital investment in the United States has significantly increased leading to a dramatic upward pressure on tuition prices. This dramatic increase in tuition levels has ...
A human relevant rat model of breast cancer [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Estrogen receptor (ER) status is an important prognostic factor of human breast cancer. ER+ breast cancers, which make up 95% of human breast cancers, have a good prognosis because the growth of these tumors is dependent ...
Energy scavenging from the human body for powering prosthetics [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Our research centers on extending battery life of electronic prosthetics by constantly recharging their batteries with energy scavenged from the body. There are many projects in existence where energy has been scavenged ...
An opportunity for small scale soybean processing [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Missouri is the 6th largest soybean producing state according the USDA, producing 194.18 million bushels in 2006. US soybean production in 2006 approached nearly 3 billion bushels. As the US soybean production increases, ...
Empowerment through journalism: social change through youth media production in northeast Brazil [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Journalism is a process in which people can begin to understand their realities and can be used as a powerful force in democratic societies for or against change. Specifically, youth journalism engages students in identifying ...
Grief: A gendered approach to the elegies of Plath and Lowell [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Landmark studies by psychologists Kalish and Reynolds in the 1970s and de Ridder in 2000 have confirmed distinct differences in grieving strategies between men and women, but the complex problem of grief remains ambiguous. ...
The salience of novel words in speech directed to young children [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
When children begin to learn vocabulary, they tend to learn more nouns than verbs (Goldfield, 1982; Nelson, 1973). Several explanations for this noun bias have been offered. One possibility is that the way nouns are used ...
Photolytically-controlled release of dexamethasone [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
