Raman Studies of Conformational Energies and Hydrogen Bonding in Alcohols

Description: The conformational energy differences have been determined for ethylene glycol, 2- chloroethanol, and 2,2- dichloroethanol in the neat liquid, DMSO, and H20 with Raman spectroscopy. Spectra in the 0-H valence region were utilized to determine the energy difference between interand intramolecularly hydrogen bonded species. It was found that the solvent effect on the relative stabilities of the gauche and trans rotamers of the alcohols differ significantly. The results also indicate that, unlike … more

Rapid, Approximate Multi-Axis Vibration Testing

Description: Sequential single-axis vibration testing strategies often produce over-testing when qualifying system hardware. Multi-axis excitation techniques can simulate realistic service environments, but the hardware and testing strategies needed to do so tend to be costly and complex. Test engineers instead must execute sequential tests on single-axis shaker tables to excite each degree of freedom, which the previous two decades of vibration testing literature have shown to cause extensive over-testing … more

Re-Envisioning an Eighteenth-Century Artifact: A Postmodern Reading of Tristram Shandy

Description: The interjection of a new and dynamically different reading of Lawrence Sterne’s Tristram Shandy is imperative, if scholars want to clearly see many of the hidden facets of the novel that have gone unexamined because of out-dated scholarship. Ian Watt’s assumption that Sterne “would probably have been the supreme figure among eighteenth-century novelists” (291) if he had not tried to be so odd, and the conclusion that he draws, that “Tristram Shandy is not so much a novel as a parody of a novel… more

Re-examining the Battle of the Bulge : Assessing the Role of Strategic Intelligence and Coalition Warfare Against the 1944 Wehrmacht

Description: The 1944 German Ardennes offensive failed. It was overly ambitious, built on erroneous assumptions, insufficiently supported by logistics, and depended on the weather for success. Yet, the offensive achieved more than it should have given the strength and combat experience of the Allied armies in Europe. Previous attempts to explain the limited success of the German offensive have emphasized the failure of Allied strategic intelligence - Ultra. Intelligence is an accurate, but incomplete explan… more
