Bioprinting: Development of a novel approach for engineering three-dimensional tissue structures [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Bioprinting is a tissue engineering technique in which spherical cell aggregates, the "bio-ink", are deposited into biocompatible hydrogels, the "bio-paper", by a 3-axis "bio-printer". The aggregates can be deposited into ...
Effect of transgene introgression site on gene migration from transgenic b. napus to b. rapa [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
There is a growing concern of the possible transgenic introgression from GM plants into agricultural weeds, which has stimulated research in the process of crop to weed gene flow. Crop to weed gene flow often involves the ...
Vocabulary growth through reading in adolescents with language learning disabilities: A case study [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Background. The amount of vocabulary development that takes place during the school-age years is impressive; children acquire about 3,000 words a year (Beck & McKeown, 1991). A primary means of vocabulary development during ...
QTL analysis for genes for brace root angle in zea mays l. [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Brace roots play a major role in determining amount of lodging, and are responsible for a significant portion of water and nutrient uptake. Using the randomly intermated B73 x Mo17 (IBM) RIL mapping population, we are ...
Artificial selection on genes for epigenetic regulation in maize [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Maize (corn) was domesticated from teosinte through a single domestication event in Mexico about nine thousand years ago. This domestication brought about the original landrace maize varieties that were spread though out ...
Hysteresis and dither in a metering poppet valve [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The objective of the following thesis is to reduce the hysteresis of a hydraulic flow control valve through the use of dither. A hydraulic valve system, used in controlling the valve and collecting and converting the ...
Effects of pro-inflamatory cytokines on polarized rat parotid Par-C10 monolayers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Sjögren's syndrome (SS), an autoimmune disorder, is distinguished by inflammation and salivary gland cell death, leading to xerostomia (dry mouth). The G protein-coupled P2Y2 receptor (P2Y2R) is up-regulated in response ...
Effects of exercise on bone parameters in the oim mouse model [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Previous studies have shown that mechanical loading on the skeleton acts as an anabolic stimulus, including changes in bone geometry, bone mineral density, and mechanical properties. Increases in these properties may improve ...
Thermal status for different breeds of dairy cattle exposed to summer heat stress in a grazing environment [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
A study was conducted to investigate thermal balance of lactating dairy cattle managed in an intensive managed rotational grazing system. The farm was located at the University of Missouri Southwest Research Center in ...
Domain specific interaction of S-RNase binding protein with the stylar 120 kDA glycoprotein in nicotiana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Through the process of evolution, many flowering plants have developed a biochemical mechanism to prevent self-pollination and pollination by closely related plants. Gametophytic self-incompatibility (SI) is one such system ...
Producing practical uses for biodiesel byproducts through the conversion of glycerol [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
With biofuels such as biodiesel and ethanol becoming increasingly popular alternatives to fossil fuels in our society, the question becomes one of economics. The production technologies are quickly becoming available, but ...
Factors affecting long-term counts of drumming ruffed grouse in Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Ruffed grouse were nearly extirpated in Missouri during the early 1900's because of habitat loss but several populations were re-established by reintroductions. The number of drumming-male grouse has been surveyed on the ...
Do young children recognize the sound system of their native language? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Children must learn the phonological rules of their language (what sounds are allowable). For example, a word cannot begin with [zw] in English, but it can in German (e.g., zwiebel). English-speaking adults all know that ...
TRI: Bridging the gap between wireless sensor networks and autonomous agents [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Wireless Sensor Networks (WSNs) can offer vast amounts of real-time data about environments. These real-time data streams are an important resource for the ever-increasing number of autonomous agents. Robots can use WSN ...
Nano-synthesis of Energetic Materials [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Energetic materials are defined as substances in which fuel and oxidizer react chemically to release energy. The amount and rate of energy released by this reaction can be improved by increasing the amount of interfacial ...
Effects of endocrine disrupters on the zebrafish embryo [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Endocrine disrupters have been shown to cause irreversible changes in fetal development of mice. These man-made chemicals are found in plastics and pesticides and could be hazardous to humans. Interestingly, hormone ...
Thermal performance of sintered and non-sintered capillary heat pipes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The current study is being conducted to better understand how interior capillary geometry/design and interior surface treatments may affect the thermal performance of sintered and non-sintered, grooved heat pipes. The ...
Comparative selectivity of various Salmonella typhimurium strains in targeting prostate cancer cells [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Recent studies indicate that non-virulent strains of serovar typhimurium () have tumor-targeting activity. Indeed, S. typhimurium has been observed to selectively target cancer tissue by a ratio of over 1000:1. However, ...
