Second harmonic generation (SHG),
a nonlinear optical tool, was used to
characterize DNA bound through a
chemical linker to the flat surface of a
hemispherical lens. Contact angle
measurements were used to guarantee
that the chemical linker did not hydrolyze
under experimental conditions. SHG
experiments followed the effects of salt...
By combining cultural theory with empirical data, this dissertation asserts that late-twentieth-century mainstream theatre had the potential to support emergent ideologies in the U.S. context. The study finds fault with those who dismiss mainstream theatre based on its commercialism and shows how a production's mainstream status may position its emergent...
Pollination is a reproductive necessity in the majority of the world’s flowering plants. Pollen limitation threatens plant reproduction, particularly in self-incompatible species. Although assessing pollen limitation usually requires pollen supplementation experiments, alternative methods support the findings of traditional pollen supplementation experiments.
From the 1990s through the 2000s, gross-out comedy – in the broadest terms, the style of physical comedy that emphasizes bodily functions and fluids, transgressive imagery and behavior, and shock value and disgust – triumphed as a subgenre of popular narrative film and television comedy. Gross-out comedy first emerged as...
This final report contains information on years 6-7-8 (2004-2007) of TEA-21 funded projects designated A487, W420, and A212. The report was submitted by Morris E. Fine and Semyon Vaynman in 2007.
Theoretical analysis of DNA bridge-mediated electron transfer (ET) led to the proposal that photoinduced ET might occur via either superexchange or hopping mechanisms. Electron transfer has been proposed to occur via a superexchange mechanism at short distances and via a hopping mechanism at longer distances. However, a crossover in mechanism...
Conventional perfusion magnetic resonance imaging with dynamic susceptibility using a contrast agents has been playing a dominant role on diagnosing a variety of cerebral nervous system disease due to lack of radiation and widespread availability. However, reliable quantification of cerebral perfusion has been elusive and challenging.
The bookend method is...
Structural dynamics in three polymer blend systems, differing largely with respect to morphology, have been investigated. The first system, composed of two immiscible homopolymers, exhibits a microstructure of micron-sized droplets dispersed in a matrix phase. We have examined small-angle x-ray scattering (SAXS) as a new approach for conducting in situ...
Alkenylsilanes of varying chain lengths are investigated as simultaneous chain transfer agents + comonomers in organotitanium-mediated olefin polymerization processes. Ethylene + alkenylsilane polymerizations were carried out with activated Me2Si(Me4C5)(NtBu)TiMe2 and (-CH2CH2-3,3'){(5-indenyl )[1-Me2Si(tBuN)]}2Ti2Me4 precatalysts. Alkenylsilane incorporation levels follow the trend C8H15SiH3 < C6H11SiH3 ≈ C4H7SiH3 < C3H5SiH3. Long-chain branching levels versus...
The interior point (IP) method for nonlinear programming was pioneered by Anthony V. Fiacco and Garth P. McCormick in the
early 1960s. The basis of IP method restricts the constraints into the objective function (duality
( http://en.wikipedia.org/wiki/Duality_%28optimization%29) ) by creating a barrier function. This limits potential solutions to
iterate in only...
