Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases on the major road...

(University of Missouri--Columbia, 2009)
of log grade through the harvest cycle shows the highest increments at Cordoba region. Dendrometric variables such as heartwood, sapwood, and diameter and crown height are good estimators of tree volume, taper and branch modeling....
Rivers running through : an urban environmental history of the Kansas Cities and the Missouri River
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An environmental history of Kansas City and an urban history of the Missouri River, this dissertation shows how interconnected the city and the river were through the twentieth...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The environment was altered...
Nectar in nicotiana : pollinator associations, sources of variation, and evolutionary consequences
(University of Missouri--Columbia, 2007)
significant heritable component was detected for nectar volume and energy, as well as corolla tube length, in an experimental population of Nicotiana alata. Although phenotypic correlations were significant for all measured traits, only two correlations had a...
Mathematical problems from cryobiology
(University of Missouri--Columbia, 2009)
Cryobiology is the study of life anddeath at low temperatures and provides a fascinating setting for applied mathematics. The interdisciplinary nature of cryobiology mirrors the diversity of applications ranging from animal ...
Resource selection by black-footed ferrets in relation to the spatial distribution of prairie dogs
(University of Missouri--Columbia, 2007)
Once extinct in the wild, the black-footed ferret (Mustela nigripes) is one of the rarest mammals in North America. Reintroductions of ferrets at 13 sites over 10 years have resulted in only 3 self-sustaining populations. ...
Media usage of journalism students of the University of Missouri--Columbia
(University of Missouri--Columbia, 2007)
? A survey of journalism students at the University of Missouri-Columbia, the oldest and one of the most prestigious journalism schools in the country, was conducted to answer these questions. The link to a Web-based survey was distributed by email...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
Space use and resource selection by Eastern spotted skunks in the Ouachita Mountains, Arkansas
(University of Missouri--Columbia, 2007)
of western Arkansas. During two years of field work we collected locations at 28-hour intervals for 33 eastern spotted skunks. Using kernel-based utilization distributions and the volume of intersection index analysis, we found significant seasonal...
The sublethal effects of methoxyfenozide on the field orientation and courtship behavior of Cydia pomonella (Linnaeus) (Lepidoptera: tortricidae)
(University of Missouri--Columbia, 2008)
The sublethal effects of ecdysone agonist methoxyfenozide on the mating behavior and field orientation of codling moth, Cydia pomonella (Linnaeus), was examined. Five different lure types were placed in the upper canopy ...
Nanomechanical property characterization of femoral head materials
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Orthopedic Implants under long-term physiological loading could produce changes in the surface mechanical properties and possible failure. The knowledge of mechanical properties...
Occupancy modeling of forest carnivores in Missouri
(University of Missouri--Columbia, 2008)
My research used infrared remote cameras, trackplate boxes, and scat transects to survey for carnivores at 53 sites throughout the southern forested region of Missouri. Cameras and track-plates both detected Eastern spotted skunk (Spilogale putorius...
The relative impact of principal managerial, instructional, and transformational leadership on student achievement in Missouri middle level schools
(University of Missouri--Columbia, 2007)
of a larger study of middle level education being conducted by the Middle Level Leadership Center at the University of Missouri-Columbia. Two survey forms were used to collect data for this study. One survey collected data on managerial...
Development and evaluation of a terrestrial animal-borne video system for ecological research
(University of Missouri--Columbia, 2008)
Ashland, Missouri. My research shows that our AVEDs are powerful new tools for ecological research that do not elevate stress levels of captive white-tailed deer and enable ecological research opportunities that traditional methods (e.g., radio telemetry...
Analysis of landscape characteristics surrounding deer vehicle accidents in St. Louis County, Missouri
(University of Missouri--Columbia, 2008)
Increased suburbanization of rural landscapes is leading to a greater number of human animal interactions. One of the most dangerous and costly of these interactions is collisions between vehicles and white-tailed deer (Odocoileus virginianus...
