Single-component polymeric precursors to SiC/Si3N4/C/BN and Si3N4/BN ceramic nanocomposites were synthesized via hydroboration and dehydrocoupling of vinyl-containing cyclotrisilazanes. The polymer-to-ceramic conversion process was investigated by 13

Sumatriptan is a 5-HT1B/1D-receptor agonist which also has affinity for 5-HT1F-receptors. The vasoconstrictor effects of sumatriptan are thought to be 5-HT1B-receptor mediated and these receptors have been shown to be expressed in human cranial blood

A study of the coupling and propagation of electron plasma waves excited by waveguide arrays is presented. The waves are generated in a low-temperature, linear plasma column in a homogeneous magnetic field. As predicted from a theoretical model, unde

The Precambrian core from a basement test well in Mingo County, West Virginia, is granodiorite with minor quartz monzonite and tonalite. The potassium-argon method indicates a date of 939 ± 34 m.y. The core shows local shearing; microveins of serici

A theoretical and experimental study of the coupling and propagation of electron plasma waves excited by waveguide arrays and electrostatic structures is presented. The waves are excited in a low temperature, linear plasma column in a homogeneous mag

Coatings of chlorite, illite, hematite, chert or carbonate on quartz grains may inhibit quartz cementation. Although these coatings do not always prevent formation of overgrowths, they commonly cause the growths to form with unique features. Recognit

Many phyllosilicate-bearing sandstones in central and southern West Virginia have undergone considerable spheroidal weathering. The formation of the concentric shells was apparently promoted by expansion of phyllosilicates as the shells developed in

Samples from wells in western West Virginia and southern Ohio indicate that the Mt. Simon (Cambrian) and Rose Run (Cambro-Ordovician) sandstones are well sorted and well rounded. Most of the sands are feldspathic with some units being arkosic. Carbon
