The purpose of this work was to compare intracranial magnetic resonance angiography (MRA) image quality using three different radiofrequency coils. The three coil types included a reduced volume quadrature birdcage coil with endcap, a commercially available quadrature birdcage head coil, and a four-element phased-array coil. Signal-to-noise ratio (SNR)(More)
In Lake Matano, Indonesia, the world's largest known ferruginous basin, more than 50% of authigenic organic matter is degraded through methanogenesis, despite high abundances of Fe (hydr)oxides in the lake sediments. Biogenic CH₄ accumulates to high concentrations (up to 1.4 mmol L⁻¹) in the anoxic bottom waters, which contain a total of 7.4 × 10⁵ tons of(More)
In this paper, we report on the development of a novel multiple thin-slab projection-reconstruction acquisition technique. To eliminate the slab boundary artifact, the slabs are highly overlapped and only a small fraction of the projection view angles are sampled at each slab position. After Fourier transformation in the slice direction, there are(More)
Self-assembled monolayers (SAMs) of alkylsiloxanes were patterned by microcontact printing @CP) on a number of substrates: A1/A1&, SUSi02, TiN/Ti02, glasses, indium tin oxide (ITO), and plasma-modified polyimide. The patterned SAMs on these surfaces define and direct the selective chemical vapor deposition (CVD) of copper using
The reduction of Fe during bacterial anaerobic respiration in sediments and soils not only causes the degradation of organic matter but also results in changes in mineralogy and the redistribution of many nutrients and trace metals. Understanding trace metal patterns in sedimentary rocks and predicting the fate of contaminants in the environment requires a(More)
Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway(More)
Recently we have begun to explore the role of temperature in optical intervalence charge-transfer (IVCT) processes.' For symmetrical mixed-valencecomplexes, we find that the energetics of IVCT are essentially unaffected by changes in temperature.' For asymmetric complexes, on the other hand, substantial energetic effects can exist, at least for valence(More)
