The Expression Of The Crf1 Gene In Mouse Embryonic Development, Margaret Gruber
The Expression Of The Crf1 Gene In Mouse Embryonic Development, Margaret Gruber
Presidential Scholars Theses (1990 – 2006)
A mouse gene cloned in the laboratory of James and Olivia Smith at Baylor College of Medicine was found to be involved in motor function. This gene was named CRFl for Clq-Related Factor 1, and using in situ hybridization, it was found to be expressed mainly in the brainstem of adult mice. There is a gene similar to the CRFl gene in humans. By determining this gene's role in mouse development, more will be known about the development of human motor function.
To determine the stage of embryonic development at which the expression of this gene …

The Use Of Rapd To Detect Genetic Variation In Populations Of Liatris Aspera Michx., Duane Joseph Kitchen
Dissertations and Theses @ UNI
The tall grass prairie is one of the most degraded and fragmented ecosystems on earth. Interest in conserving, restoring, and reconstructing tallgrass prairie began early in the 1900s, and has increased dramatically since the 1960s. Early restoration and reconstruction efforts relied primarily on seed collected from prairie remnants near the planting site, but with the increase in prairie planting efforts came a greater demand for large quantities of affordable, viable seed of native prairie species. Following an increase in the use of cultivated varieties (cultivars) of seed, concerns over the loss of genetic integrity of local populations and low genetic …
Pre-Performance Routines And Rhythm: A Comparative Study, Blake Wade Miller
Pre-Performance Routines And Rhythm: A Comparative Study, Blake Wade Miller
Dissertations and Theses @ UNI
The present study was designed to investigate the effects of pre-performance routine rhythm on novel motor task success. At the center of the study was the comparison of differing characteristics of two theories of motor control: the dynamical systems theory and the schema theory. It was hypothesized that an even pre-performance routine rhythm would be more advantageous to task success than an uneven preperformance routine rhythm, regardless of the rhythmic characteristic of the task. The results concluded the contrary to be more accurate, and indicated that task success was more likely to occur when the pre-performance routine rhythm was congruent …

Effects Of Sludge Application On Prairie Establishment, Brenda Joan Durbahn
Dissertations and Theses @ UNI
Native prairie in Iowa has all but disappeared since the development of agricultural land by European settlers over the past 165 years. Reconstructing prairie is one way to replace some of the acreage that was lost. A byproduct of settling an area is the generation of garbage and other wastes. Currently there is a surplus of sludge, the waste product of waste water treatment facilities. This material is usually disposed of in landfills, used on agricultural land or reclamation projects.
A small area of prairie was reconstructed on the top of a closed portion of the Black Hawk County Solid …
