Design and construction of multicomponent spheroidal assemblies on the nano-scale via the self-assembly approach
(University of Missouri--Columbia, 2006)
spherical multicomponent assemblies via the selfassembly approach. Chapter 2 will describe the formation of very large molecular capsules based upon the self-assembly of six macrocycles called the C-alkylpyrogallol[4]arenes. These molecular capsules are held...
Decadal mass balance of the Antarctic ice sheet from satellite radar altimetry and its contribution to global sea level change
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this research, we estimated the decadal mass balance of the Antarctic ice sheet using the European Space Agency's ERS-1 and ERS-2 satellite radar ...
Topics in spectral and inverse spectral theory
(University of Missouri--Columbia, 2006)
This dissertation is concerned with two major classes of operators and provides various spectral and inverse spectral results for them. In the first part of this work a special class of one-dimensional discrete unitary ...
Studies of natural products that reveal novel strategies for efficient modification of DNA
(University of Missouri--Columbia, 2006)
novel molecular recognition features of the natural product azinomycin using similar tools (Chapter 4). We characterized novel, reversible chemical reactions of leinamycin (Chapter 3). Amongst these were reversible DNA-alkylation and reversible adduct...
Analytical study of the spectral-analysis-of-surface-waves method at complex geotechnical sites
(University of Missouri--Columbia, 2006)
The Spectral-Analysis-of-Surface-Waves (SASW) method is an accepted means of measuring shear wave velocity (VS). In some settings, SASW measurements have produced results that were inconsistent with results from other ...
Sharp estimates of the transmission boundary value problem for dirac operators on non-smooth domains
(University of Missouri--Columbia, 2006)
This thesis derives the sharp estimates for the transmission boundary value problems (TBVP) for Dirac operators in Lipschitz domains in the three dimensional setting. Most of the transmission problems considered in the ...
Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)
Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ...
Fuel depletion analyses at the Missouri University Research Reactor
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In developing, assembling and updating safety analysis cases for nuclear power and research reactors, fuel depletion plays a major role and ultimately ...
System modeling and control design of a two-stage metering poppet-valve system
(University of Missouri--Columbia, 2006)
control methods that comprise modified PI control, LQG control, H [mobius] control, and nonlinear feedback control are used to make a closed-loop poppet system. The nonlinear controller is only applied to the nonlinear system and certified by Lyapunov...
Long-term study of successional trends in an oak-dominated forest of central Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Changes in species composition and forest structure were studied over a 36-year period in the Baskett Research and Education Area (BREA) in central ...
The clothing and textile research base: an author cocitation study
(University of Missouri--Columbia, 2006)
This is a study of the clothing and textile research base using author cocitation analysis. The study uses a custom database from a 15 year period, containing all citations in the field's leading journal: the Clothing and ...
A genotypic comparison of plasticity of root system development during soil drying in soybean (Glycine max (L.) merrill)
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Water deficit is responsible for significant losses in soybean (Glycine max (L.) Merrill) yield under dryland conditions. Under drought, increases in ...
Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)
, and of cobalt rod-based phosphate ISEs were satisfactory for measuring N, P, and K ions over typical ranges of soil concentrations. The nitrate ISEs, when used in conjunction with the Kelowna extractant (0.25M CH₃COOH + 0.015M NH₄F), provided soil NO₃-N values...
Sensory analysis of low fat strawberry ice creams prepared with different flavor chemicals and fat mimetics
(University of Missouri--Columbia, 2006)
The objective of this study was to understand the release behavior of five strawberry flavor compounds in ice cream with fat mimetics, and to reformulated low-fat ice cream with Simplesse(R) to match the flavor profile of ...
Road work ahead: the transformation of the colonnaded street in sixth and early seventh century Palestine and Arabia
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This thesis explores the urban character of colonnaded streets in the late Roman provinces of Palestine and Arabia. By using archaeological data from ...
Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
