While much is known about the properties of small organic molecules in aqueous solution, one quantity that has eluded a detailed understanding is their entropy. Different functional groups interact in diverse ways with water molecules and thereby inf

In addition to lowering cholesterol, statins may alter endothelial release of the vasodilator NO and harmful superoxide free radicals. Statins also reduce cholesterol intermediates including isoprenoids. These are important for post-translational mod

In many near-surface applications, detailed subsurface characterization is important. Characterization often is obtained using ground-penetrating radar (GPR) or shallow seismic-reflection (SSR) imaging methods, depending upon depth of interest and su

Wave migration is a technique in which the reflectivity of the Earth is interpreted by extrapolating the fields measured on the surface into the ground. The motivation of this paper is to develop a generalized imaging algorithm based on a matched-fil

Three distinct seismic reflections were obtained from within the upper 2.1 m of flood-plain alluvium in the Ar- kansas River valley near Great Bend, Kansas. Reflections were observed at depths of 0.63, 1.46, and 2.10 m and confirmed by finite-differe

The growing professional interest in ground-penetrating radar (GPR) is driving the need to formulate methods for characterizing the performance capabilities of GPR systems. Because a number of different factors, such as antenna ringing, noise, radio

A 1-km profile of in situ stress and geophysical log data was acquired in the Wilkins well to study the relationship between rock properties and in situ stress contrasts. The Wilkins well penetrates Devonian clastic rocks on the Appalachian Plateau n

Many of today's well construction projects are technically and economically challenging. Examples include deepwater exploration wells in the Gulf of Mexico, offshore field development projects such as Hibernia, Newfoundland, Canada and onshore field
