Genetic variation associated with adaptive traits in the African forest (Loxodonta cyclotis) and savanna elephant (L. africana) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
There are two species of African elephant, the forest (Loxodonta cyclotis) and savanna elephant (L. africana). The savanna elephant is believed to have diverged from the forest species approximately 2.6 million years ago. ...
Traits associated with brace root characters implicate light and hormonal signaling pathways [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Maize brace roots provide the plant with access to water and nutrients in the soil, increase stability, and improve lodging resistance. The goal of this study is to connect brace root traits to traits linked to developmental ...
Automatic controllers: Stability and performance in clinical anesthesia
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Anesthesiologists manually control the rate of drug infusion to maintain a desired conscious level (BIS index) for a patient during surgery. With new technological advances, Control Engineers now can automate this drug ...
Water flow sensor for eldercare [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Changes in hygiene habits can be an early indicator of mental and/or physical decline in elders. Since personal hygiene activity accounts for much of the water use in a home, and since much of this activity happens in ...
Impact of effective instruction within middle school classrooms on at-risk student problem behavior [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Teachers are increasingly faced with students who present challenging behavior in the classroom. When faced with such challenges, educators look for effective ways to manage problem behaviors, as well as to prevent problems, ...
Novel inhibition mechanism and potent antiviral activity of translocation-deficient reverse transcriptase inhibitors [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Nucleoside RT inhibitors (NRTIs) are among the most potent anti-HIV agents and act as chain terminators because they lack a 3'OH. However, this feature can reduce affinity for RT compared to the analogous dNTP substrate, ...
Carbon nanotubes and their composites with nanodiamond for thermal packaging: Syntheses, characterization and modeling [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In the family of carbon-based nanosystems, carbon nanotubes (both single- and multi-walled) are cylindrical carbon molecules with many extremely useful properties that make them ideal for use in multitude of technological ...
Efficacy of a modified constraint induced movement therapy protocol in the clinical setting [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Constraint induced movement therapy (CIT) is an intervention strategy used by rehabilitation therapists for people who have experienced stroke. Traditional CIT protocols require participants to wear a restraint on their ...
Generating Gbx2 antibodies: A useful tool in determining developmental mechanisms regulated by GBX2 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The GBX class of homeobox genes is comprised of Gbx1 and Gbx2. Both loss-of-function and gain-of-function studies in mice have shown that Gbx2 is vital for normal anterior hindbrain development of mammalian organisms. To ...
Vegetation classification in urban nature areas in Columbia, Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Urban nature areas are often identified by local governments with no thought to their ecological characteristics or conservation value. We used a vegetation classification procedure, entitation, to classify vegetation types ...
Silencing of three members of the cytochrome p450 family of genes to uncover their role in iron regulation in A. thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Iron absorption and distribution by an organism needs to be tightly regulated because iron is essential but in excess it can be dangerous and may even result in death. Through microarray analyses of iron-starved Arabidopsis ...
Development of a RF Class E amplifier to power a ferroelectric plasma thruster [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Class E amplifiers are a special class of electronic amplifiers which are highly efficient at delivering power at high frequencies. Class E amplifiers consist of a signal generator, switch, and two LC resonant circuits. ...
Epithelial-mesenchymal transition of brain tumor cells is differentially regulated in response to dexamethasone
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In the epithelial-mesenchymal transition of tumors, the loss of cohesivity and the migratory capability of cells determine the invasiveness and therefore the malignancy of the cancer. Understanding these biophysical ...
Analysis of Arabidopsis thaliana mutants defective in the oligopeptide transporter OPT3
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The transport of peptides across membranes is a phenomenon found in both prokaryotes and eukaryotes as a method of obtaining amino acids, nitrogen, and carbon. Peptides can be transported by ATP-dependent transporters, as ...
Membrane permeability of Bovine Ooctyes to Propylene Glycol and the application to the improvement of Cryopreservation
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In this study, the goal was to determine the permeability parameters of bovine oocytes for water (Lp) and Propylene Glycol (PPG) at temperatures of 30, 20, 10, and 5°C. By determining permeability parameters, we can model ...
The measurement of residual feed intake to determine feed efficiency of pregnant Hereford heifers
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The large potential improvement in profitability is what makes feed efficiency such a studied and concerned topic in the beef industry today. Currently, no herd exists in the United States that has been selected solely for ...
Host-guest complexes to molecular encapsulation of hydrogen
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Science has always been about man learning from and attempting to mimic nature. In supramolecular chemistry this possibility is evident due to particularly interesting architectures of natural shell-like containers such ...
Video game music beyond its original function: Practices, styles, and ends
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Rapidly growing in complexity of compositional practices, styles, and ends, video game music is an art form that surpasses its original function as “background music” as well as any utilitarian, stereotypical expectations ...
Comparison of regulatory regions in the mitochondrial genomes of grasses
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Regulation of transcription in plant mitochondria is not well understood. The recent sequencing of the mitochondrial genomes of 10 closely related grasses allowed a comparative analysis of regulatory regions. To look for ...
