Propagation of polarized light in skeletal muscle
(University of Missouri--Columbia, 2009)
Skeletal muscle is a very important tissue in animals and humans. Optical polarization imaging is a non-invasive method to study biological tissues and provides unique polarization contrast. An imaging system was developed ...
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...
Felix convivum : platters and transformations of dining behavior in the Roman world
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Most people in the Roman world used ceramic tableware, despite its absence in iconographical and in literary sources. This observation leads to many ...
Single carrier frequency domain equalization for broadband wireless communications
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This thesis discusses different channel estimation techniques, channel equalization and various diversity schemes for broadband wireless communication ...
Kinematic analysis of cam profiles used in compound bows
(University of Missouri--Columbia, 2009)
for an eccentric-circular cam design and a one-cam one-pulley design. By iteratively determining the bow limb, cam, and cable positions a relationship between the drawn length and drawn force will produce a draw-force curve. In fact, this curve represents...
High valent uranium dioxo and imido complexes : synthesis and structure
(University of Missouri--Columbia, 2008)
Early actinide elements have attracted considerable attention in recent years due to the need for rigorous advancements in spent nuclear fuel recycling and remediation technologies, and for their emerging versatility in ...
pH sensitive fluorescent sensors
(University of Missouri--Columbia, 2007)
and remain off (pH=5.5). When stimulated the cell will exocytose the sensor and at pH=7.4, the sensor will fluoresce. The synthesis of pH sensitive fluorescent chemosensors for amines and their properties is described....
Analysis and modeling of direct selective laser sintering of two-component metal powders
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Direct Selective Laser Sintering (SLS) is an emerging technology of Solid Freeform Fabrication (SFF) that 3-D parts are built from the metal-based ...
The massive tornado outbreak of May 2003
(University of Missouri--Columbia, 2005)
In May of 2003, 516 tornadoes touched down in the central portion of the United States, which is a record for the most tornadoes for any single month. There were fourteen deaths associated with those tornadoes that touched ...
