(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] GLC7 encodes the catalytic subunit of protein phosphatase 1 (PP1) in the budding yeast Saccharomyces cerevisiae. Glc7 binds different regulatory ...
A genetic approach to determine river otter abundance in Missouri
(University of Missouri--Columbia, 2010)
Extirpated from Missouri by the 1930s, river otters (Lontra canadensis) were reintroduced by the Missouri Department of Conservation (MDC) from 1982-1992. Since the reintroductions, concerns over the legitimacy of otter ...
Regulation of calcium signaling by p130PH in astrocytes
(University of Missouri--Columbia, 2009)
Ca2+ signaling is a characteristic form of astrocyte excitability, but its role in ischemia is not clearly understood. Our previous study (Ding et al., 2009) demonstrated that astrocytes exhibit enhanced Ca2+ signaling ...
Monte Carlo neutronic simulations for a new approach to parametric INAA and Mo-99 production feasibility at MURR
(University of Missouri--Columbia, 2009)
A novel approach to parametric instrumental neutron activation analysis at MURR has been established. In particular, a detailed MCNP5 steady-state model of the MURR core was developed. The model, which was based on the ...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
This project comprises several chemical routes to produce soy-based polyols for future use in polyurethane foam applications. Soybean oil was polymerized by heat and catalyst to increase molecular weight, and viscosity for ...
Principal, board member, and staff perceptions of female public school superintendents instructional leadership
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study examined the instructional leadership of female superintendents as perceived by board members, principals and staff members who work directly ...
Gas sorption in engineered carbon nanospaces
(University of Missouri--Columbia, 2009)
Vehicular storage of gaseous fuels is a key enabling technology for the two pillars of a non-petroleum based transportation economy natural-gas vehicles and hydrogen fuel cell vehicles. My research focuses on the development ...
Surface and deep water circulation in late Cretaceous North Atlantic greenhouse ocean
(University of Missouri--Columbia, 2009)
This research provides the first of its kind empirical data regarding the evolution of Maastrichtian surface to deep ocean circulation in the North Atlantic. Differences in foraminiferal abundances and oxygen and carbon ...
Statistical analysis for survival data with missing information
(University of Missouri--Columbia, 2009)
As a branch of statistics, survival analysis, which is often referred to as "reliability theory" in engineering, has a long history. While in practical problems, some information might be missing. This dissertation discusses ...
Pronghorn migration and resource selection in southwestern North Dakota
(University of Missouri--Columbia, 2009)
Wildlife managers need pronghorn (Antilocapra americana) movement data in North Dakota because harvest quotas are based on a summer survey, which might not represent the distribution of pronghorn during the fall hunting ...
