Impacts of Precipitation, Land use Land cover and Soil type on the Water Balance of Lake Chad Basin
(2013)
Lake Chad Basin (LCB) has experienced drastic changes in land cover and poor water management practices during the last 50 years. The successive droughts in the 1970s and 1980s resulted in a decrease in surface water and ...
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...
The Impact of Climate Variability and Land Cover Change on Groundwater Resources in The Niger River Basin
(2021)
The Niger River Basin (NRB) has experienced severe droughts and floods under a significant change of the land use and land cover (LULC) with increasing population over the years. The present study is to understand the ...

(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...
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...
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....
Toward a common market in residency: international migration and regional integration
(University of Missouri--Columbia, 2005)
This paper further develops models of regional migration, particularly in continents integrating regionally as it magnifies the importance of immigrant behavior for economists and policy-makers. I outline the history of ...
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...
Intense Shallow Magma Sediment Mingling within Dikes at Guffey Butte Maar, Idaho
(2022)
The interactions between magma and shallow unconsolidated sediments on the way
to the surface influences the eruption behavior and products. Phreatomagmatic eruptions are
a result of the interaction of magma and water ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
Dipstick urinalysis for the diagnosis of acute UTI
(Family Physicians Inquiries Network, 2013)
Approximately two-thirds of women who present with classic symptoms of acute UTI have bacterial infection of the bladder. Dipstick urinalysis moderately improves the accuracy of clinical symptoms in establishing or excluding ...
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...

(University of Missouri -- Kansas City, 2019)
The Santa Rosalía Basin (SRB), Baja California Sur, is a transtentional to rift basin
that formed during the opening of the Gulf of California. The Boleo Formation is the oldest
and dominant sedimentary fill of the ...
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...
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...
Are structural changes in the agri-food sector causing the instability of parochial ag-producers?
(University of Missouri--Columbia, 2009)
Parochial (Amish and Mennonites) agriculture producers have been known for their stability (historically large numbers) (Kollmorgen, 1943). Though, more recently, the percentage of parochial members who are ag-producers has been steadily declining...
