Resolution of phylogenetic patterns within monocots [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Monocotyledons or monocots are one of two groups of angiosperms that comprise ca. 60,000 species, 92 families, and 12 orders. Exemplary monocots include agaves, grasses, sedges, bromeliads, palms, gingers, orchids, irises, ...
Biochemical characterization of phosphoproteins involved in defense signaling in the plant Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Plants use an innate immune response for protection against pathogens that can be activated by elicitor molecules, such as a peptide from the flagellar tail of bacteria or the oligosaccharide chitin. Receptors reside at ...
Thermal Management of Low Enriched Uranium in the University of Missouri Research Reactor (MURR) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Medical radioisotopes facilitate medical imaging. The University of Missouri Research Reactor (MURR) is exploring the potential of producing one such isotope, molybdenum-99, using a new process that utilizes low enriched ...
The effects of anxiety and depression on the academic achievement of African American youth [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Multiple factors might influence African American youths' academic performance, but few predictors have been subjected by empirical scrutiny. Anxiety and depression are documented as being negatively associated with academic ...
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 ...
Integration of programmable robotic arm with engineered nanopore [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Engineered nanopores have many potential applications in biosensing at the single molecule level. However, research of the pore is hindered by the time consuming and highly sensitive synthesis of a single pore. The size ...
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 ...
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 ...
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. ...
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)
This investigation was aimed at developing an assay for characterizing samples gathered from tissues on which microvascular permeability studies were being conducted. In particular, we were looking for evidence of proteolytic ...
International media and economic policy: A comparative media analysis of 2002 U.S. steel tariffs [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
This paper compares American and European media coverage of the U.S. Emergency Safeguard Measures for steel which were imposed from March 2002-Dec. 2003 and levied tariffs of up to 30% on some steel imports. Of European ...
On air: Evaluating streaming MPEG4 video performance over wireless networks [Novinger abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
There is not a clear consensus on how open-standard video streaming technologies perform across wireless computer networks. Wireless networking technologies have become nearly ubiquitous, particularly in residential networks, ...
Computational and experimental assessment of public dose from normal research reactor operations [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The Missouri University Research Reactor (MURR) in Columbia, Missouri is interested in the amount of the Argon-41 being produced and released to the environment. The objective of this work is to know what operations within ...
Analysis of the effects of dietary ascorbic acid on a beneficial wasp [abstract]
