(University of Missouri--Columbia, 1988)
Mutations affecting the ability of the photosynthetic bacterium Rhodobacter capsulatus to fix nitrogen (Nif- ) have previously been mapped into six linkage groups (I-VI) by transduction with gene transfer agent (GTA). ...
Forest harvest effects on soil chemical properties and nutrient concentrations in Ozark Highland soils
(University of Missouri--Columbia, 2010)
Mixed hardwood systems of the Missouri Ozark Forest Ecosystem Project are harvested using clearcutting (CC) and single-tree selection (STS) regeneration methods. This work indicates possible effects of regeneration method ...
Use of Jacobians for inverse kinematics of articulated robots : a study on approximate solutions
(University of Missouri--Columbia, 2020)
In the context of articulated robotic manipulators, the Forward Kinematics (FK) is a highly non-linear function that maps joint configurations of the robot to poses of its endeffector. Furthermore, while in the most useful ...
Simulation and experimental study of the multichanneling rimfire gas switch
(University of Missouri--Columbia, 2005)
Since 1985, the Rimfire switch has been used extensively in accelerators at Sandia National Laboratories. Demands for increased future accelerator performance require improvements to the Rimfire switch. This thesis is both a theoretical...
The political economy of property rights : institutions, interests, and economic prosperity
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An influential literature argues that strong property rights are at the core of modern economic prosperity. Theoretically, property rights reduce the ...
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)
Distributed watershed hydrologic/water quality (H/WQ) models are ubiquitous tools for watershed management. Despite advancements, there remain impediments for end-users. This study presents a practical framework for use ...
Low sensitivity to, and craving for, alcohol in naturalistic and laboratory settings
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Low sensitivity to alcohol is a well-established risk factor for the development of an alcohol use disorder. This risk is transmitted along several ...
Spring establishment of tall fescue utilizing sunn hemp as a companion crop under rotational grazing management
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/01/2024] Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) is the predominant perennial cool season grass used for forage in Missouri. It demonstrates a bi-modal seasonal yield distribution with ...
Early detection of health changes in the elderly using in-home multi-sensor data streams
(University of Missouri--Columbia, 2022)
The rapid aging of the population worldwide requires increased attention from health care providers and the entire society. For the elderly to live independently, many health issues related to old age, such as frailty and ...
Paleoethnobotany of Buena Vista: a case study of ritual feasting in late Preceramic Peru

This project examines plant macroremains, phytoliths and starch remains recovered from special archaeological and architectural contexts at Buena Vista (11°43'51.72"S, 76°58'5.45"W) , an inland site in the lower Chilló́n ...
Spatiotemporal patterns of earthquakes and their implications for earthquake hazards
(University of Missouri--Columbia, 2022)
This work focuses on characterizing spatiotemporal patterns of earthquakes, their possible causes, and their implications for seismic hazard assessment. I studied both local and global earthquakes in the view of complex ...
The effect of big four office size on audit quality
(University of Missouri--Columbia, 2007)
Larger offices of Big Four accounting firms are argued to provide higher quality audits than smaller offices due to greater in-house experience and more expertise in ministering the audits of publicly listed clients. In ...
Gene expression profiling of bovine ovarian follicular selection
(University of Missouri--Columbia, 2006)
Lack of, or abnormal, ovarian follicular development is a major factor associated with impaired fertility in mammals. However, development of new treatments is limited by our poor understanding of ovarian follicular ...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
Water and soil are two key elements for life on this planet, and improving and preserving their quality are of prime importance. Various human actions including use of intensive chemicals in agriculture have accelerated ...
Forest adaptation and transition in the eastern united states under climate change : a forest landscape modeling method
(University of Missouri--Columbia, 2018)
