s by authors outside the U.S. Geological Survey were reviewed and in some cases slightly revised following the workshop. Key issues addressed in the workshop include the following: (1) The configuration, areal extent, and temporal development of the chain of interconnected lakes which emptied into Death Valley during periods of the Pleistocene. (2) The development of Mojave River drainage in co...

fXY = fYX. Problems of this type can be multiplied indefinitely, and a general theory of partial differentiation in the large to cover all such problems is desirable. We have started to construct such a theory. Among the various theorems which we have proved are three which we announce in this note as follows. THEOREM 1. Let f(x, y) be of class C' on an open point set H. Let the four second par...

The Fiji Platform developed as an island arc in the Tertiary. Extensional and transpressional tectonics have deformed the fill of extensive sedimentary basins within the Platform. These basins commonly contain over 3 km of stratified deposits. Five deep petroleum-exploration wells were drilled between 1980 and 1982, but all were dry. There remain reasonable prospects, however, because none of t...

The nature of the surface of Venus is one of the keys to answering fundamental questions about the origin and evolution of the terrestrial planets and is of critical significance to comparative planetology. The last 25 years of solar system exploration have provided unprecedented views of the Earth, Moon, Mars, and Mercury. These views have shown that the smaller terrestrial planetary bodies (t...

a split plot factorial experiment based on randomized block design in four replications was performed in order to study the effect of three levels of compost (zero, 10 and 20 ton dry matter/ha), in main plots and three levels of nitrogen (zero, 100 and 200 kg/ha pure nitrogen) and three levels of phosphorous (zero, 60 and 120 kg/ha p2o) on corn yield. the effect of compost on different characte...
