Plasma wave excitation on meteor trails in the equatorial electrojet
The unusual properties of meteor echoes recently observed at Jicamarca [Chapin and Kudeki, 1994] are attributed to the growth and propagation of plasma irregularities along meteor trails depositedExpand

Radar interferometric imaging studies of long‐duration meteor echoes observed at Jicamarca
A large number of long-duration (≥15 s) meteor echoes were detected at the Jicamarca Radio Observatory on two nights in early August 1990 during an evening electrojet experiment. Using anExpand

Improved absolute radiometric calibration of a UHF airborne radar
The AirMOSS airborne SAR operates at UHF and produces fully polarimetric imagery [1]. The AirMOSS radar data are used to produce Root Zone Soil Moisture (RZSM) depth profiles. The absoluteExpand

Synthesis and hypoglycemic activity of substituted 8-(1-piperazinyl)imidazo[1,2-a]pyrazines.
A series of alkyl- and halo-substituted 8-(1-piperazinyl)imidazo[1,2-a]pyrazines were prepared using two approaches, the condensation of alpha-halocarbonyl derivatives with an aminopyrazine or theExpand

Effects of an alpha 2-adrenoceptor antagonist on glucose tolerance in the genetically obese mouse (C57BL/6J ob/ob).
This study examines the effects of a relatively selective alpha 2-adrenoceptor antagonist, 8-(L-piperazinyl)imado-[1,2-alpha] pyrazine (compound A), and the preferential alpha 2-agonist clonidine onExpand
