This second part of a two-part study examines the lightning and charge structure evolution of the 29 June 2000 tornadic supercell observed during the Severe Thunderstorm Electrification and Precipitation Study (STEPS). Data from the National Lightning Detection Network and the New Mexico Tech Lightning Mapping Array (LMA) are used to quantify the total and cloud-toground (CG) flash rates. Addit...

In this article, a novel structure of photonic crystal fiber with nearly zero ultra-flattened chromatic dispersion and ultra-low confinement loss is presented. By replacing the circular air-holes of two first rings with the elliptical air-holes, a fiber with outstanding features of chromatic dispersion and confinement loss is designed. The proposed structure is optimized for operating in a wide...

We present results from a 49.3 ks Chandra X-ray observation of the strongly interacting dumbbell galaxies NGC 4782(3C278) and NGC 4783 that constrain the kinematics of the interaction and models for bending the radio jets associated with NGC 4782. The galaxies are embedded in an approximately spherical distribution of group gas, centered on NGC 4782, that, away from the interaction region, is n...

South East England has historically been the main focus of economic activity and wealth production in the UK. From about 1730 to 1930, this pattern was temporarily modified by the Industrial Revolution which generated new industries in the Midlands and North of England, Wales and Scotland. But since then London and the South East have reasserted their primacy, first through new manufacturing in...

INTRODUCTION Located in the central Pacific between 4° and 14°north latitude and 160° and 173° east longitude, the Marshall Islands consist of two nearly parallel groups (the Ratak or Sunrise and the Ralik or Sunset Chains) of twenty-nine atolls and five table reefs, totalling 181 km2 of land and 10,455 km2 of lagoon area. Together these two chains extend about 1,130 km north to south and appro...

Oriental hybrid lily “Arabian Red” mother scales were stored in moist cocopeat and perlite (1:1) for 3 or 5 months at 25 ̊C. The numbers of scale bulblets per mother scale were nearly identical in two durations. Increasing storage duration promoted the growth of roots (number and length) and No. scales per scale bulblets. And, diameters of scale bulblets were more in longer storage duration (5 m...

Seismic reflection profiles, drill-hole data, and geologic maps delimit the form of normal faults and Tertiary sedimentary rocks in the southern half of the Cache Valley basin in northern Utah. Dips of faults and sedimentary rocks were estimated from time-migrated reflection profiles by using the stacking velocities for the data. At the southern end of the basin, the East Cache fault zone is li...

We report the results of a 5-field mosaic of the central 15pc of the Galaxy in the (1,1) and (2,2) lines of NH3. Two narrow filaments or streamers are seen running parallel to the Galactic plane. The southern streamer appears to carry gas directly toward the nuclear region from the 20 km seccloud. The eastern streamer, which we will denote the molecular ridge, appears to be the denser part of t...
