Assemblage structure and shallow-water habitat use by small-bodied fishes at lower Missouri River sandbars
(University of Missouri--Columbia, 2007)
Populations of many native big-river fishes have declined since channelization and flow regulation contributed to losses of shallow-water habitat (SWH) on lower Missouri River (LMOR). Existing point and wing-dike sandbars represent a potentially...

Effects of Selected Contaminants on the Physical, Chemical, and Geotechnical Properties of Aquifer Solid
(2014)
contaminants on the hydraulic conductivity of sand. Bulk sand samples from the Missouri River Valley aquifer— a major source of groundwater supply in the U.S. Midwest— were collected for this study. Sand samples, representing the aquifer and vadose zone...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
Soybean (Glycine max L. Merrill) is one of the most important legume crops grown worldwide. However, without phosphorus (P) fertilization, soybean yields often are limited by phosphorus availability. Phosphorus is an ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation consists of three essays on behavioral finance. In the first essay, we proposes a new daily market-level investor sentiment index (Photo Pessimism) constructed...
Investigation into lowering cement clinker content using available materials
(University of Missouri--Kansas City, 2012-08-17)
Reducing cement clinker with mineral addition has been considered an efficient way
of saving energy, lowering CO2 footprint of cement and concrete industries. The trend of
using limestone as mineral addition in cement ...

(Food and Agricultural Policy Research Institute (FAPRI) at the University of Missouri-Columbia, 2004-02)
FAPRI, with significant input from the local community, has developed this analysis defining how current agricultural practices in the upper Shoal Creek Watershed affect water quality.
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...
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...
Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
(University of Missouri--Columbia, 2010)
-matrix landscape combinations common in five central Missouri counties; 2) evaluate the temporal occurrence of these mosquito taxa; 3) assess relationships between regional weather factors and the occurrence and abundance of the mosquito fauna; and 4) categorize...
