Conversion of waste corn cobs to activated carbons for natural gas (methane) adsorption
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Adsorbed Natural Gas (ANG) is an alternative energy source technology that uses micropores in adsorbent materials to store natural gas. Activated carbons, which are useful adsorbents with a highly porous form of carbon are ...
Developing proteomics approaches for identifying new, redox-regulated proteins
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
For many years it was thought that hydrogen peroxide was only a toxic substance to cells. However, recent work has revealed that hydrogen peroxide can be utilized by organisms as a cellular signaling molecule. Hydrogen ...
Retension of knobs in chromosome tips in maize
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Knobs are deeply staining chromosomal sites on maize chromosomes. Molecularly, they are composed of a 180 base pair repeat. Their positions on the chromosomes are variable but usually internal in maize. In relatives, the ...
Death by the pounds: The effects of television on the obesity of African-American children and adolescents
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study examined the direct effects that television programming has on the obesity of African-American children and adolescents based upon the top three stations viewed by African-American children and adolescents during ...
The effect of timber stand improvement practices on the abundance of Pileated Woodpeckers
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The Pileated Woodpecker (Drycopulus pileatus) is a large woodpecker that requires large dead trees within a mature forest. I investigated how forest management practices affect the Pileated Woodpecker. Timber stand improvement ...
Identification and deconvolution of overlapped peaks derived from raw 2D PAGE images [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
A standard approach for the analytical separation of proteins in the field of proteomics is the use of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), which separates a complex crude protein samples from a ...
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 ...
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 ...
Ga-Ga over 68Ga: Novel chelates for PET heart imaging [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Heart disease remains one of the leading causes of death in the United States. Improved, function-specific imaging agents promise to augment current diagnostic techniques, leading to better treatment and fewer deaths. ...
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 ...
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 ...
Surface modification of hydroxyapatite particles for biomaterial applications [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The interface between a filler material and a matrix can have a substantial impact on the properties of composites. This is especially true of nanoscale materials due to their increased ratio of surface area to mass. The ...
Immigrant women and domestic abuse: Barriers to seeking services [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The experience of an immigrant woman in the United States who has been abused by an intimate partner presents an especially complex legal and social service situation due to her status as an immigrant. Any added complications ...
Modification of a Calcein-based assay for proteolytic activity [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
