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 ...
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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
Childhood overweight, food intake, and physical activity among Whites, Blacks, and Hispanics [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Childhood overweight has tripled in the last three decades for children 6-11 years of age. Overweight children are at higher risk for health problems and psychosocial issues. Although studies show Black and Hispanic children ...
Recovery of locomotor function following spinal cord hemi-transections in larval lamprey [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
In vertebrates, reticulospinal (RS) neurons in the brain activate spinal motor networks to initiate locomotor behavior. Following spinal cord injury (SCI), RS neurons no longer communicate with the spinal cord, and animals ...
How volume of water effects in morphological growth and number of endomycorrhizas on P. delicatum [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
In alpine tundra plants, water is the most important environmental factor of plant growth. And the endomycorrhiza is the greatest symbiotic organism. Because, it provides Nitrogen and Phosphorus to the plants and it obtains ...
Maize brace root formation and correlation with juvenile nodes and tassel structure [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Global warming causing changes in weather patterns is making drought a more frequent occurrence. Drought is a major limiting factor of maize production worldwide. To maintain high production levels, it is important to ...
Efficient organization of genetic data for easier statistical analysis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
When biological experiments are run, specifically those examining genetics, huge amounts of data are produced. This data is hard to organize and even harder to analyze without organization. When faced with a vast amount ...
Characterizing a human embryonic stem cell model of placental development [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
When human embryonic stem cells (hESC) are treated with BMP4, they differentiate into trophoblast cells, the major cell type of the placenta. There are three main types of trophoblasts: syncytio-, cyto-, and extravillous ...
