Several disciplines like Environmental Toxicology, Epidemiology, Public Health and Geology have been the basis of the development of Medical Geology in Uruguay during the last decade. The knowledge and performance in environmental and health issues have been improved by joining similar aims research teams and experts from different institutions to face environmental problems dealing with the po...

This report summarizes the major findings of a United States Geological Survey (USGS)-funded project entitled the "West-Central Florida Coastal Studies Project" and managed by the USGS Center for Coastal Geology and Regional Marine Studies in St. Petersburg, FL. USGS scientists from Woods Hole and Menlo Park were involved as well. This project was a co-operative five-year venture with scientist...

A project is underway to map die indoor radon potential for New York State at the township level. Through a detector distribution program the New York State Department of Health has a database of over 36,000 basement screening measurements. The address field for the indoor measurement data is being linked to latitude and longitude coordinates using data files containing coordinate information. ...

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...
