Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
(University of Missouri--Columbia, 2022)
volumes and diameters for statistical comparison between the two different size classes of coprolite. In combination with volume renders of the segmented material, we also adopt more traditional methods such as thin-section petrography and scanning...
Adsorption interactions of UV-aged microplastic particles with sulfamethazine
(University of Missouri--Columbia, 2022)
Due to growing plastic demand and production without proper waste management, microplastics have become common around the world throughout diverse systems. At the same time, increased detection of antibiotics in the ...
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...
Irrigation practices and costs in southeastern Missouri - 1959
(University of Missouri--Columbia, 1961)
Field crop irrigation is a relatively new production technique in Missouri. Prior to this investigation, only United information was available concerning costs and returns. The research reported here was assigned to determine (1) the costs...
Some characteristics and environmental sensitivities of taxpayers taking the United States political contribution tax credit during 1979-1982
(University of Missouri--Columbia, 1988)
This study was designed to determine characteristics of taxpayers taking the political contribution tax credit from 1979 to 1982. This work is similar to studies on the effectiveness of tax incentives in promoting positive ...
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...
To study the effect of pregnancy and of nursing on the maintenance requirement of mares
(University of Missouri--Columbia, 1916)
Abstract taken from three paragraphs of the Introduction to this thesis: A clear understanding of the main principles underlying the nutrition of farm animals has never been more important to the stock farmer than at the ...
Adjusting organizational structure for cooperative longevity : Missouri farmers association, 1920 - 1950
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The objective of this qualitative exploratory study is to analyze the process which led Missouri Farmer Association (MFA) to dramatically change its organizational structure...
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. ...
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...
Resolving space-time strain paths of the Panamint and Cottonwood Mountains, eastern California, through bedrock thermochronology and detrital geochronology
(University of Missouri--Columbia, 2020)
this transect also record cooling between 80-50 Ma, similar to AHe and ZHe ages from a transect in the Cottonwood Mountains. Paleodepth reconstructions of samples from the Panamint Range suggest that the northern part of the range experienced 4.2-7.2 of vertical...
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...
Hydrodynamic characteristics and capillary-assisted heat transfer enhancement of non-condensing/condensing two-phase flows
(University of Missouri--Columbia, 2020)
Interfacial characteristics of two-phase flows were studied through visualization experiments and numerical simulation using computational fluid dynamics (CFD) based on the volume-of-fluid (VOF)-continuum surface force (CSF) method...
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 ...
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...
Northern bobwhite brood ecology and population dynamics in southwest Missouri
(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) have experienced widespread, long-term population declines. Bobwhite populations in Missouri have declined 2.7% annually between 1966 and 2015, and 3.5% annually between 2005 and 2015, for a cumulative loss...
A shellabration of early life : exploring the taphonomy, diversity, and distribution of small shelly fossils surrounding archaeocyathid reef systems in the Harkless System, Death Valley, NV
(University of Missouri--Columbia, 2023)
poorly preserved; however, µCT volume imaging confirms that external morphological features are insufficient alone to differentiate species from other similar coniform fossils. The second study investigates changes in SSF richness and diversity...
Influence of characters of ear and kernel upon the germination of maize
(University of Missouri--Columbia, 1912)
of the ear and kernel which have a marked influence upon the yield. This is so universal that we have score cards which set forth the ideal type of ear and give certain values to the different characters. In general, the score cards are alike and all agree...
Effect of plagioclase crystallization on liquid and magma viscosity in the Anorthite-diopside-dorsterite-quartz system
