Topics in harmonic analysis and partial differential equations: extension theorems and geometric maximum principles
(University of Missouri--Columbia, 2011)
the resulting extension procedure is nonlinear in this case. The results presented in this part are based upon work done in collaboration M. Mitrea. In the second part of the thesis we prove that an open, proper, nonempty subset of ℝn is a locally Lyapunov...
Two phases of extension in North China since Mesozoic :a numerical study
(University of Missouri--Columbia, 2013)
The North China Craton was formed around 1.8 Ga by collision and amalgamation of the Eastern and Western blocks. It remained tectonically stable since then until the Mesozoic, when its eastern part experienced widely distributed extension...
Perceptions of secondary agriculture teachers and 4-H youth development extension personnel regarding cooperative behavior
(University of Missouri--Columbia, 2008)
Numerous cooperative agreements and memoranda exist at the federal and state levels that suggest or require cooperation between the Extension agents and agriculture teachers. The purpose of this descriptive study was to determine the degree...
Bismuth impurity effects on copper: examining embrittlement in immiscible binary metallic systems
(University of Missouri--Columbia, 2013)
conditions. This thesis presents a comprehensive parametric model of the effects of temperature and the presence of Bi on the fracture response of the sample. The experimental data provide an extensive matrix of conditions within a decreased ductility trough...
Why do people post online? : an analysis of the online review posting (ORP) scale as an extension to the web motivation inventory (WMI)
(University of Missouri--Columbia, 2013)
Online motives are one of the most important starting points for understanding online consumer behavior (Rodgers & Thorson, 2000). The present research draws from existing research and the larger uses and gratifications literature in an effort...
Articulated learning trajectories related to the development of algebraic thinking that follow from patterning concepts in middle grades mathematics
(University of Missouri--Columbia, 2010)
, and balance were considered in analyzing the mathematical development of these concepts. Comparisons based on the disciplinary perspectives showed key differences among the ALTs identified across textbooks, including the extent to which authors presented...
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...
Application of deep learning networks to crime prediction
(University of Missouri--Columbia, 2013)
better crime prevention. This thesis discuss the use of deep learning networks, an advanced machine learning technique, as applied to the task of predicting future crimes. First, an extensive set of experiments of various types of network structures...
The production, applications and economic study of activated carbon for large scale production including an educational study on undergraduate laboratory modules
(University of Missouri--Columbia, 2010)
was developed to study the mass and energy balance involved with operation of an AA Alkaline battery under a load current. An extension of the module allows evaluation of laboratory assembled batteries using granular anodic/cathodic materials. The system allows...
Sequence and secondary structural analysis of a novel class of RNA aptamers that inhibit reverse transcriptase
(University of Missouri--Columbia, 2012)
either C or U). Aptamer secondary structural families are correlated with inhibitory behavior. F2Pk aptamers inhibit a broader range of RT subtypes compared to F1Pk. In the present work we present results of a screen into the inhibitory behavior of a...
The role of witchcraft accusations as an alternative form of self-expression
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Witchcraft has been extensively dismissed or simplified in popular thought, media and scholarship as a negative force that aggravates social hostilities and hinders peaceful...
Fusion frame constructions and frame partitions
(University of Missouri--Columbia, 2013)
Fusion frames consist of a sequence of subspaces from a Hilbert space and corresponding positive weights so that the sum of weighted orthogonal projections onto these subspaces is an invertible operator on the space. Despite extensive literature...
"The sphinx of the nineteenth century": Helena Blavatsky's syncretism in Britain, 1887-1891
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Helena Blavatsky, the enigmatic co-founder of the Theosophical Society, has an extensive biographical record, much of which is dedicated to proving or disparaging...
Living acts of semiosis: John Dewey's model of esthetic experience as key to a temporal theory of signs
(University of Missouri--Columbia, 2007)
nuanced model for a theory of signs. Anthropologist Victor Turner's theory of social drama is shown to be compatible with the pragmatists' assumptions about experience. Based on Turner's extensive anthropological fieldwork, social drama theory can...
Forgetting in short term memory : the effect of time
(University of Missouri--Columbia, 2008)
Forgetting in short-term memory has been studied extensively and yet no consensus has emerged to explain its cause. Two theories continue to provide competing explanations of forgetting in short-term memory: decay and interference. Decay presupposes...
Simplified model for reinforced concrete beams under catenary action
(University of Missouri--Columbia, 2010)
and a system of springs that represents the load extension behavior and moment rotation behavior of a reinforced concrete beam element. Spring properties are based on material, geometric, and design parameters. The tensile definition of the axial...
Extension theorems in vector spaces over finite fields
(University of Missouri--Columbia, 2008)
We study the L[superscript p] - L[superscript r] boundedness of the extension operator associated with algebraic varieties such as nondegenerate quadratic surfaces, paraboloids, and cones in vector spaces over finite fields. We obtain the best...
Voluntary teeth clenching during exercise in a natural environment: prevalence and gender differences
(2013)
during leg extension and general weight-lifting exercises in 7 male and 10 female subjects recruited from UMKC soccer teams. All subjects gave informed consent to participate in IRB-approved study protocols. Laboratory surface EMG recording during static...
Mechanical properties of complex biological systems using AFM-based force spectroscopy
(University of Missouri--Columbia, 2005)
An atomic force microscope (AFM) was designed and built to study the mechanical properties of small collagen fibrils and the plasma membrane of living cells. Collagen is a major component of bone, skin and connective ...
