Tensile strength, shear strength, and effective stress for unsaturated sand
(University of Missouri--Columbia, 2006)
It is generally accepted in geotechnical engineering that non-cohesive materials such as sands exhibit no or negligible tensile strength. However, there is significant evidence that interparticle forces arising from capillary ...
Development and evaluation of a site stormwater analysis calculator intended for the State of Missouri utilzing regional best management practices
(University of Missouri--Columbia, 2023)
The Site Stormwater with Best Management Practices (BMPs) Analysis Calculator was created to be utilized in the State of Missouri for developing or re- developing property. Simplistic and conservative stormwater evaluations utilizing regional...
Associations between psychosis risk and emotional distress disorders with cortical surface morphometry
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Neuroimaging studies have consistently found structural cortical abnormalities in schizophrenia, especially in structural hubs. However, it is unclear what...
Statistical and simulation methods for evaluating stationary and mobile work zone impacts
(University of Missouri--Columbia, 2018)
when traffic volumes are under 1400 veh/hr/ln, and preferably under 1000 veh/hr/ln, due to the drastic increase in the number of conflicts. In addition, three data driven models were developed to predict traffic speed inside a MWZ: a linear regression...
An in depth evaluation of internal criteria for determining the number of clusters in a data set
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Clustering procedures partition data sets into groups, minimizing the distance within clusters while maximizing the distance between clusters. Clustering can be a powerful tool...
Top-soil root architecture characteristics of obsolete and modern soybean cultivars and shoot and seed nutrient contents
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max Merr.) is one of the most important cash crops worldwide. It is widely used to produce oil and protein for food and animal feed. Soybean grain...
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....
Pluton source varition over two magmatic pulses in the white-inyo range, central-eastern California : implications for paleozoic and mesozoic tectonic reconstructions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as it is the easternmost...
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 ...
The use of silage to counteract the effect of cottonseed meal on the composition and market qualities of butter
(University of Missouri--Columbia, 1917)
Text from page 58: In general, this experiment shows that very slight effects on the composition of butter result from feeding cottonseed meal with a liberal ration of silage; and that larger changes in the fat constants ...
Examining positive schizotypy's relationship with openness facets, maladaptive openness, and other maladaptive traits
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/1/2024] Positive schizotypy is a trait reflecting increased risk for schizophrenia-spectrum disorders and includes symptoms such as magical beliefs and unusual perceptual experiences. The normative ...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
question of how pre-existing topography controls lava flow system structure in volume-limited flows (Soldati et al., accepted). I concluded that a steep slope results in a single, stable channel, whereas a gentle slope results in an unstable, braided...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
Agriculturally produced ethanol, a renewable resource, may be reformed noncatalytically into hydrogen by a novel process utilizing supercritical water, which acts synergistically both as a solvent and as a reactant. By ...
Pricing arrangements for one grade of milk
(University of Missouri--Columbia, 1970)
"The dairy industry has experienced an accelerated rate of change in recent years. These changes have been widespread, affecting the entire industry rather than isolated segments such as production, marketing, or consumption. ...
