Spatial distribution and historical dynamics of threatened conifers of the Dalat Plateau, Vietnam
(University of Missouri--Columbia, 2011)
The Dalat Plateau is one of several biodiversity hotspots in Vietnam. It is considered to be one of five centers of plant diversity and one of three endemic bird areas in the country. Almost half of the conifer species ...
University of Missouri Independent Study, 1997-1998 bulletin
(University of Missouri--Columbia, 1997)
Associations between cumulative genetic influence for risk-taking and hazardous alcohol use in two independent samples
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A propensity for risk-taking may be associated with hazardous alcohol-related behaviors especially in men. Prior research indicating substantial heritability and genetic overlap...
Mass and Metallicity of Five X-Ray-bright Galaxy Groups
(American Astronomical Society, 1999)
We present ASCA X-ray observations of a sample of Ðve groups selected from a cross-correlation of the ROSAT All-Sky Survey with the White et al. optical catalog of groups. These X-rayÈbright groups significantly increase ...
Validation of a Subject Specific Canine Hind Limb Model with Emphasis on an Anatomical Stifle
(University of Missouri--Kansas City, 2010)
canine hind limb using a bi-axial tester to move the limb through loading profiles and Optotrak system to collect the kinematics of the hind limb for these profiles. A model was built using bone geometries created from MRIs post processed using a polygon...
Vegetation management along roadside and railroad right-of-ways
(University of Missouri--Columbia, 2018)
to restrict weed emergence. Field studies in central Illinois (three), Missouri (one), and Kansas (one) were established in 2015 and 2016 to compare fall single versus multiple application timings of residual herbicides from fall through the following summer...
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)
.e. an aquatic-terrestrial zone (ATTZ), within the main channel of the lower Missouri River. Predictive models of sandbar morphometry (area, wetted perimeter, elevation, and water-surface slope) were developed to determine how changes in discharge affect...
Values of the Euler Function in Various Sequences
(2005)
Let φ (n) and λ(n) denote the Euler and Carmichael functions, respectively. In this paper, we investigate the equation φ (n)r = λ(n)s, where r ≥ s ≥ 1 are fixed positive integers. We also study those positive integers n, ...
Gravitoelectromagnetism: A Brief Review
(arXiv, 2008)
The main theoretical aspects of gravitoelectromagnetism ("GEM") are presented. Two basic approaches to this subject are described and the role of the gravitational Larmor theorem is emphasized. Some of the consequences of ...
A Climatology of Northern Hemisphere Blocking
(American Meteorological Society, 2006-03)
for a better characterization of blocking events with additional information on blocking parameters such as the location of the blocking center, the intensity, and extension. Additionally, a new tracking procedure has been incorporated following...
Supercritical CO2 extraction of porogen phase: An alternative route to nanoporous dielectrics
(Materials Research Society, 2004)
We present a supercritical CO2 (SCCO2) process for the preparation of nanoporous organosilicate thin films for ultralow dielectric constant materials. The porous structure was generated by SCCO2 extraction of a sacrificial ...
Simultaneous local resolution along a rational valuation in two dimensional positive characteristic function fields
(University of Missouri--Columbia, 2022)
zero by Abhyankar. He calls this simultaneous resolution. The essential new case that occurs in positive characteristic p is a chain of Artin-Schreier extensions. It is known that simultaneous local resolution is true (along a nondiscrete rational rank...
The role of middle leaders in fostering organizational learning in a state cooperative extension service
(University of Missouri--Columbia, 2005)
This qualitative study explored the nature of organizational learning and the role of regional directors (RDs) and program directors (PDs) as mid-level leaders in fostering organizational learning in one cooperative extension organization. In...
Three essays on entrepreneurship : theory, measurement, and environment
(University of Missouri--Columbia, 2007)
This dissertation consists of three essays. In Essay One, I question the conventional wisdom that economic transactions are governed either by the price mechanism or by the authority of the firm. I argue that the exchange ...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
Development of a FRET biosensor to detect the pathogen mycoplasma capricolum
(University of Missouri--Columbia, 2005)
Mycoplasmas are a species of bacteria that invade any type of cell and are adaptable to changing environments. We are developing an optical biosensor based on Fluorescence Resonance Energy Transfer (FRET) for detection of ...
The influence of climate and population structure on East Asian skeletal morphological variation
(University of Missouri--Columbia, 2022)
Objectives: Recent studies have shown that global variation in body proportions is more complex than previously thought as some traits formerly associated with climate adaptation are better explained by geographic proximity ...
A comparison of forest change detection methods and implications for forest management
(University of Missouri--Columbia, 2005)
technique used extensively in the eastern United States for forest change detection. This project tested the usefulness of this easy and inexpensive technique by applying it to the Missouri Ozark forest landscape in order to detect changes in forest biomass...
Regulation of Gene Expression by Non-coding RNAs in Arabidopsis and Brachypodium
(2014)
Expansion of high-throughput sequencing technology has increased our understanding
in the importance of pervasive transcription and the resulting indispensable molecules, noncoding
RNAs (ncRNAs). A significant effort has ...
Regression analysis of interval-censored failure time data with non proportional hazards models
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Interval-censored failure time data arises when the failure time of interest is known only to lie within an interval or window instead of being observed exactly. Many clinical...
