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...
Generation, collection and characterization of nanoparticles and their diffusion in arbitrary tumor and normal tissue geometry
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nanoparticles have unique electronic, optical, mechanical, magnetic and chemical properties that are significantly different from those of the bulk materials. Because of this...
Modeling the financial impact of management decisions on loblolly pine (Pinus taeda) production
(University of Missouri--Columbia, 2010)
Located primarily in the southeastern United States, Loblolly pine (Pinus taeda L.) is a variety of Southern yellow pine that is often planted by non-industrial private landowners seeking a beneficial long-term investment ...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(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....
A genetic approach to determine river otter abundance in Missouri
(University of Missouri--Columbia, 2010)
's effects on sport fish populations have sparked controversy. The MDC responded by increasing efforts to monitor river otter populations, using latrine site counts to measure relative abundance across several rivers in Missouri. However, the actual number...
Polyurethane foams from novel soy-based polyols
(University of Missouri--Columbia, 2008)
Polyurethane foams and molded plastic films were prepared by reacting isocyanates with polyols containing 50% of vegetable oil-based polyols and 50% of petroleum-based polyols. The vegetable oil-based polyols included epoxidized soybean oil...
Photoacoustic detection of circulating tumor cells
(University of Missouri--Columbia, 2013)
based on the change in refractive index was developed to detect individual melanoma cells. The sensitivity of the optical based detector was high and has the resolution to determine the presence of extremely low number of metastatic and cultured cells (2...
Effect of plagioclase crystallization on liquid and magma viscosity in the Anorthite-diopside-dorsterite-quartz system
(University of Missouri--Columbia, 2006)
SiO2 (CMAS) glasses were synthesized as analogs for dacitic and basaltic lavas. Liquid viscosities were measured between 101 and 1013 Pa s, over the temperature range of approximately 1600 to 700⁰C, using concentric cylinder ...
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...
Simulating the effects of riparian zone delineation and management practices on landscape pattern and timber production
(University of Missouri--Columbia, 2004)
to erosion or pollutant discharge. Analyzing the effects of different buffering scenarios upon landscape pattern and timber volume provides forest managers with better tools for deciding the best action to take in balancing timber harvest with the biological...
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...
Economic analysis of woody biomass harvesting in the Missouri Ozarks
(University of Missouri--Columbia, 2010)
An integrated mechanized timber harvest thinning treatment to remove small diameter trees and merchantable saw logs was conducted on 30 acres of the Missouri, Ozarks in the summer of 2009. Two silvicultural treatments (single tree selection...
Numerical solutions to the Poisson equation in media surrounding multiple arbitrarily shaped bodies
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The dissertation describes a general, efficient, and parallelized approach to solving the Poisson equation in the volume surrounding multiple, arbitrarily shaped bodies. Green...
Designing a LANDIS PRO harvest module and examining the effects of temporal resolution on simulation outcomes
(University of Missouri--Columbia, 2012)
and testing of a disturbance module that simulates harvest events in the LANDIS PRO model. The design operates on quantitative attributes such as number of trees and basal area to control harvest events, giving the user the ability to parameterize harvest...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
Plateau of south-central Missouri, and Bear Cave Hollow (BCH), one of TCC's surface drainage streams, bed load entrainment and transport dynamics of mainly siliciclastic material, was evaluated using hydrological measurements and 670 painted tracer...
Developing a stand density module in LANDIS to improve simulation realism of stand dynamics
(University of Missouri--Columbia, 2009)
Long-term landscape modeling is dependent on various forest dynamics including large-scale disturbances, environmental effects, land management and stand-scale succession. The stand density module was designed for LANDIS ...
Mesoporous iron oxide energetic composites with slow burn rate, sustained pressure and reduced ESD sensitivity for propellant applications
