High surface area carbon based batteries [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Lead acid batteries have some flaws that prevent them from being used in applications such as electric vehicles. Their low energy densities, problems with corrosion, sulfation, and inability to withstand deep discharges ...
Survey on vocal fatigue in classroom teachers: Profile based on teaching level [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Voice production is a complex task involving coordination of several systems in our body. Voice plays a crucial role in speech production. Without voice, speech will be inaudible. Voice problems hinder communication ...
Thermal performance maps for forced air cooling of ruggedized electronics enclosures [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Based on standard commercial form factors, this study explores chassis-level air cooling limits for ruggedized military electronics constrained by pressure drop requirements and fin manufacturing capabilities. Numeric and ...
Rotational excitation of carbon dioxide due to collision with a liquid surface [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
To improve our understanding of collisional energy transfer at a gas-liquid interface, we have investigated collisions of carbon dioxide molecules with a simple atomic liquid surface. Our particular focus here is on the ...
Modeling a gas puff z-pinch as an RL circuit load [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
A Z-pinch is process through which current is passed though a column of plasma and the resultant JxB force acts to "pinch" the plasma to smaller and smaller radii. More specifically, a gas puff Z-pinch is a Z-pinch that ...
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 ...
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 ...
Efficient IP multicasting [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Unicast connections are a single connection between two computer hosts. While they may work well for one-to-one communication or non-real-time applications, these connections may not be as efficient for one-to-many or ...
Effect of progestin treatment on formation of persistent follicles in beef cows [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Effective estrous synchronization protocols frequently utilize progestins (melengestrol acetate [MGA] and Controlled Internal Drug Release [CIDR] inserts) to synchronize estrus and ovulation. Previous research demonstrated ...
Laser ablation of necrotic tissue to promote healing in burn injury [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Each year approximately 40,000 people are hospitalized due to burn injuries. The majority of our population is familiar with the superficial burns that result from overexposure to the sun, commonly known as sunburn. These ...
Development of optical models for non-invasive glucose testing [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Current blood glucose measurement techniques are invasive and uncomfortable. Developing a non-invasive technique will not only alleviate part of the pain involved with current techniques but also cost less, greatly benefiting ...
How the position of menu items on a one-page menu effects item popularity [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The subject of this research project was to determine if the menu position of an item influences the number of times it is ordered. In this particular study, one-page menus were examined. A new menu was designed where each ...
An empirical analysis of the underlying premises of the [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Over the past 30 years, there has been a debate in courts and academia over whether federalism is better protected by judicial or political safeguards. In Garcia v. SAMTA (1985), the Supreme Court ruled that it would not ...
Building reporter virus with recombinant viral proteins for analysis of resistance to antiviral compounds [abstract]

Hockey pucks: The energy of the future [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
No, not the traditional hockey pucks the Canucks play the sport they love with. These hockey pucks are much like sponges; they are blocks of activated carbon filled with incredibly small pores whose diameters measure only ...
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 ...
