Common and specific alcohol risk factors in African Americans and Caucasians
(University of Missouri--Columbia, 2010)
Considerable research evidence shows that the alcoholism risk process differs for African Americans and Caucasians (Bachman et al., 1991; Wallace et al., 2003). The current study was designed to test a model examining ...
Childhood epidemics and the demographic landscape of the Aland Archipelago
(University of Missouri--Columbia, 2018)
Historically, the introduction of childhood diseases such as measles or smallpox resulted in the infection of nearly every susceptible individual in a community. While smallpox has long been considered the deadlier of the ...
Process engineering to produce defined hierarchical structures of diatoms for wastewater polishing and micropollutant removal
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Diatoms are unicellular algae, which are among the most common types of phytoplankton. They are widespread in fresh water, oceans and soils with different sizes and morphologies...
The effects of volatiles on the viscosity and heat capacity of calc-alkaline basaltic and basaltic andesite liquids
(University of Missouri--Columbia, 2014)
Calc-alkaline basaltic magmas are volumetrically important at continental and island volcanic arcs, yet their thermal and physical properties are poorly described. These basaltic magmas are characteristically hydrous, and ...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Rising adoption of dicamba-tolerant soybeans increases the potential exposure of grapes to dicamba, where off-target injury may occur via particle or vapor drift. In 2017...

(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated relationships between reported academic stress, caffeine consumption, and illicit prescription stimulant use, as a means of better identifying students...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
of the many amphibian species for which stage-specific data are lacking. Next, I reared larvae of five species (A. annulatum, A. maculatum, A. opacum, A. talpoideum, and A. texanum) from populations along an ~200 km latitudinal gradient in Missouri, USA...
In situ polymerizing collagen for the development of 3D printed tissue engineering scaffolds
(University of Missouri--Columbia, 2018)
Natural materials have been processed and utilized as scaffold materials in the field of tissue engineering for many years. One natural material often utilized is collagen since it is the main structural protein in mammalian ...

Three dimensional reconstruction of plant roots via low energy x-ray computed tomography
(University of Missouri--Columbia, 2018)
.775. Experimental results show that the proposed root enhancement methods are robust to the number of orientational filters chosen, and are sensitive to the filter length selected. Small size filters are preferred, since increasing the filter length increases...
Assessing red wolf conservation based on analyses of habitat suitability and human perception of carnivores
