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...
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...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases on the major road...
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...

The following are objectives of this publication ... Provide a condensed history of liming research and practices in Missouri ... Summarize the methods in use at the end of the Twentieth Century to estimate the need for liming material ... Sumarize...
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 ...
Cognitive load and time based forgetting
(University of Missouri--Columbia, 2009)
Recently, various researchers have claimed that time does not play a direct role in shortterm forgetting. Instead, they claim that time is only related to forgetting because it is correlated with other factors that cause ...
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....
Assessing the Impact of Changing Climate on Agriculture in Missouri and the use of Crop Insurance as Adaptation Strategy (1980-2010)
(2015)
as an adaptation strategy by farmers in Missouri is driven primarily by the volume of crop production and not vulnerability to changing climate....
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...
Advantages of the no-scalpel vasectomy technique
(Family Physicians Inquiries Network, 2012)
The no-scalpel vasectomy (NSV) technique should be used instead of the standard incisional method. (Strength of Recommendation: A, based on systematic reviews, mixed-quality randomized controlled trials [RCTs], cohort ...
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...
