The Thermal Emission Spectrometer spectra of low albedo surface materials suggests that a four to one mixture of pyroxene to plagioclase, together with about a 35 percent dust component provides the best fit to the spectrum. Qualitative upper limits can be placed on the concentration of carbonates (<10 percent), olivine (<10 percent), clay minerals (<20 percent), and quartz (<5 percent) in the ...

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...

Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...

Variations in diurnal tidal stress due to Europa’s eccentric orbit have been considered as the driver of strike-slip motion along pre-existing faults, but obliquity and physical libration have not been taken into account. The first objective of this work is to examine the effects of obliquity on the predicted global pattern of fault slip directions based on a tidal-tectonic formation model. Our...

The Muskingum-Cunge flood routing procedure has been incorporated into the Natural Resources Conservation Service Technical Release 20 (TR-20) hydrologic model. The TR-20 model is an event watershed hydrologic model used to analyze impacts of watershed changes (land use, reservoir construction, channel modification, etc) on volume of runoff and peak discharge. Rainfall runoff modeling is very i...

Genetic diversity of allozymes at 24 loci was studied in 23 populations of longleaf pine (Pinus pa/u.stris Mill.). including three seed orchard populations and an old-growth stand. Overall, the mean number of alleles per polymorphic locus was 2.9, the percentage of polymorphic loci was 92%. and the mean expected heterozygosity was 0.105. These values are comparable with diversity measures found...
