Examining instability in Midwestern snowstorms with lightning and thunder [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
12 individual cases of thundersnow were examined in order to determine those common atmospheric
stability characteristics that attend such storms. We found that most thundersnow events have high
bases (between 10K and ...
Physiological responses of a hyper-phototropic mutant to various light stimuli [abstract]
(2004)
Physiological responses of a hyper-phototropic mutant to various light stimuli Phototropic responses are the directional curvature of organs in response to differences in light intensity and/or quality. The experimental ...
Frequency prediction of flow induced vibration in pipes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
thing happens in power plants pipes, wherever there is a Safety Relief Valve (SRV) down the flow line, vibration will occur. This constant vibration has been identified as one of the leading causes of piping failures. The purpose of this research...
Intimate opposition: Perceived closeness as a moderator of the impact of third-party opposition on romantic relationships [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Research has examined how third parties (e.g. parent-child relationships and peer relationships) affect the quality of romantic relationships. For instance, a pair of studies investigated the "Romeo & Juliet effect," to see whether parental...
Effects of fescue toxicosis on growth and thermoregulation of rats [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tall fescue (Festuca arundinacia), a cool season forage grass, has been utilized by many farmers for over fifty year to feed livestock. Unfortunately, about half of fescue pastures are infected with an endophytic fungus ...
Isolation of soybean (glycine max) root preferential promoter [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Soybean root preferential promoter is of great use to soybean genetic engineering. Such a promoter can be used to drive a tissue specific or preferential expression of integrated genes for either disease resistance or ...
Cloning auxin-responsive genes for future study in Arabidopsis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Auxin, a plant hormone, serves as a signal for cells to grow, divide, and differentiate. Approximately 25 years ago, auxin was shown to rapidly affect the expression of specific genes. To date, only three families of auxin ...
Intrapulmonary expression of PPAR in a rat model of pulmonary hypertension [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Activation of peroxisome proliferator-activated receptor-gamma (PPARγ) inhibits vascular smooth muscle proliferation and neointimal formation associated with pulmonary hypertension. Recently, our laboratory developed a ...
Sensitization of neuroblastoma to apoptosis mediated by oncogene-specific antisense peptide nucleic acid oligomers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Apoptosis, or programmed cell death, is a major pathway by which chemotherapeutic drugs kill tumor cells. The B-cell lymphoma/leukemia-2 (bcl-2) and FLICE-inhibitory (FLIP) cellular oncogenes promote tumor cell survival, ...
Apoptosis...controlling nature's destructive process [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Apoptosis, or natural cell death, is a necessary process that occurs within living organisms in response to developmental signals or environmental cues. Cell death can be triggered and transmitted by cell surface receptors ...
Preparation of chitosan beads and membranes for industrial applications [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Industrial waste water contains a variety of toxic chemicals including toxic heavy metals that must be removed before discharging to the environment. A number of methods have been investigated to remove these heavy metals. ...
Chromatin-level regulation in maize [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Epigenetic regulation of gene expression is determined by chromatin packing. Transcriptionally active genes are associated with open, less compacted chromatin, whereas transcriptionally less active or silent genes are found ...
High performance concrete [abstract]
(2004)
In the Engineering industry, the improvement of existing materials allows for
technological advancement and the construction of more reliable structures
without over design. High Performance Concrete (HPC), a material ...
Bridges as roosting habitat for bats in southeastern Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research., 2004)
bridges and guano has been found at 30 bridges. Guano amounts, classified as low, medium or high, were used to indicate possible levels of use. Data presented are the preliminary findings. Continued surveys in spring and summer of 2004 will further...
Expression patterns of oligopeptide transporters in arabidopsis thaliana [abstract]
(2004)
Peptide transport is a universally observed cellular mechanism employed by both prokaryotes and eukaryotes to transport peptides (2-6 residues) across cellular membranes in an energy-dependent manner. These peptides, upon ...
Effects of Cimicifuga racemosa on mammary gland development in mice [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
would alter development of the mammary glands, we performed the following experiment. Thirty-two female, C57blackJ mice were obtained from the MU colony at 3-4 weeks of age. The mice were randomly assigned to either a control diet or the same diet...
Leptin concentration in mares and their subsequent offspring [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Leptin is an adipocyte-derived hormone that influences an animal's feed intake and immune response, as well as body temperature regulation in the neonate. Additionally, leptin serves as an indicator of total body fat mass ...
Lepidopteran preference test of Glossy mutants and Glossy15 allels for maize resistance [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Every year fall armyworm and Southwestern corn borer cause severe yield loss in maize. Both fall armyworm and the Southwestern corn borer are known to specifically attack the whorl leaf tissue resulting in major crop losses. ...
