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...
Aluminum alloys strengthened with coherent (L1<sub>2</sub>), nanosize Al<sub>3</sub>Sc precipitates may be used as structural materials at elevated temperatures. They are creep resistant at 300°C and exhibit a threshold stress, below which creep is not measurable. Introducing ternary alloying additions, such as rare-earth elements (RE=Y, Dy, Er), that segregate within Al<sub>3</sub>Sc...
This thesis presents results and analysis on a series of donor-bridge-acceptor (D-B-A) charge transfer systems in which we use time-resolved spectroscopy and magnetic resonance techniques to study the relationship of molecular structure to energy, charge, and spin transfer dynamics. We find that the sequence of events following the initial charge...
The authors of the article “Toward Environmentally Sustainable Digital Preservation” created this workshop as a space for participants to discuss issues of environmental sustainability in digital preservation, identify and enact change toward sustainable practices in their organizational contexts, and identify and plan further research. The workshop was run for the...
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 dissertation consists of three essays on the identification analysis of econometric models.
The first essay explores the identification question in semiparametric binary response models when all regressors have discrete support. I suggest a recursive procedure that finds sharp bounds on the parameter of interest and can be applied to...
NiTi shape memory alloy (SMA) has drawn a great deal of attention for its various applications in the medical field (orthodontics, cardiovascular stents technology, etc.) and in other engineering fields (aerospace, aircraft, automotive, etc.) as it shows shape memory effect, superelasticity and biocompatibility. The fatigue-related issues, however, are pronounced in...
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.
This manual describes use of a new hybrid autonomous crack and structural response monitoring (ACSM) system. It is designed as a low cost alternative to the research grade version employing SOMAT’s eDAQ data recording system. The concept is to combine a new field portable, 24 bit, 12 channel seismograph with...
