Issue in pollution control: interplant cost differences and economies of scale.
R.W. Pittman
1981, Land Economics (57) 1-17
Seeks evidence concerning the issues of the relative efficiencies of different institutional arrangements for pollution control and the implications of control requirements for economies of scale and barriers to entry. Data is derived from the estimation of a production function for 30 pulp and paper mills in Wisconsin and Michigan....

Ne matrix spectra of the sym-C6Br3F3+ radical cation
V.E. Bondybey, T.J. Sears, T.A. Miller, C. Vaughn, J.H. English, R.S. Shiley
1981, Chemical Physics (61) 9-16
The electronic absorption and laser excited, wavelength resolved fluorescence spectra of the title cation have been observed in solid Ne matrix and vibrationally analysed. The vibrational structure of the excited B2A2??? state shows close similarity to the parent compound. The X2E??? ground state structure is strongly perturbed and irregular owing...
Multiple asperity model for earthquake prediction
M. Wyss, A. C. Johnston, F. W. Klein
1981, Nature (289) 231-234
Large earthquakes often occur as multiple ruptures reflecting strong variations of stress level along faults. Dense instrument networks with which the volcano Kilauea is monitored provided detailed data on changes of seismic velocity, strain accumulation and earthquake occurrence rate before the 1975 Hawaii 7.2-mag earthquake. During the ???4 yr of...
Influence of PCBs in water on uptake and elimination of DDT and DDE by lake trout
Robert J. Hesselberg, Lawrence W. Nicholson
1981, Journal of Environmental Quality (10) 315-318
Researchers predicted that several hundred years would be required before DDT (1,1,1 trichloro-2,2-bis [P-chlorophyl] ethane) and its metabolites were likely to decrease to nondetectable levels in Lake Michigan. But following the ban on DDT in 1970, residues of total DDT in Lake Michigan lake trout (Salvelinus namaycush) declined rapidly from...
Improved population estimates through the use of auxiliary information

C.J. Ralph, J. M. Scott, editor(s)
1981, Book chapter, Estimating numbers of terrestrial birds. Cooper Ornithological Society Studies in Avian Biology
When estimating the size of a population of birds, the investigator may have, in addition to an estimator based on a statistical sample, information on one of several auxiliary variables, such as: (1) estimates of the population made on previous occasions, (2) measures of habitat variables associated with the size...

Potentiometric surface of the Wilcox-Carrizo aquifer; Bienville, Red River, and northern Natchitoches, and southern Webster Parishes, Louisiana
G.N. Ryals
1981, Open-File Report 80-1179
The potentiometric surface of the Wilcox-Carrizo aquifer in central northwestern Louisiana is shown by contours using data collected from 1960 to 1980. The aquifer is not affected by regional water-level declines as no large pumping centers have been developed. Seasonal water-level fluctuations in wells are generally less than 10 feet...
The seismicity of Ethiopia; active plate tectonics
P. Mohr
1981, Earthquake Information Bulletin (USGS) (13) 124-133
"But I tell you, when you look at the way the pieces of the northeastern portion of the African continent seem to fit together, separated by a narrow gulf, you could almost make a believer [in continental drift] of anybody" Astronaut Harrison Schmidt, on the view from Apollo 17. Ethiopia, descended...
Earthquakes, March-April 1981

There was on major earthquake (7.0-7.9) during this reporting period on April 24 in the Vanuatu Islands (formerly the New Hebrides islands). the series of strong earthquakes continued in Greece and caused additional casualties and damage, and Peru expereinced a moderate earthquake that caused fatalities and damage on April 18. In...

Water type and suitability of Oklahoma surface waters for public supply and irrigation, Part 3: Canadian, North Canadian, and deep fork river basins through 1979
Jerry D. Stoner
1981, Water-Resources Investigations Report 81-80
Water-quality data through 1979 in the Canadian, North Canadian, and Deep Fork River basins within Oklahoma were examined for water type and suitability for public water supply and irrigation use. Of 105 stations with available data, 47 stations or 45 percent were considered to have sufficient data for analysis. The...
Characteristics of central North Dakota wetlands determined from sample aerial photographs and ground study

Wetland characteristics were assessed from a systematic sample of 66 plots, 3.22 km2 each, drawn from a 10,041-km2 study area in central North Dakota. Each plot was visited once and 8 sets of aerial photographs were obtained in 3 years. Density of wetland basins was 11.00 ha/km2, and area averaged...

1981, Technical Paper 105
Temperature selection tests were conducted with fry of Lake Michigan lake trout (Salvelinus namaycush) exposed to PCB's, DDE and a combination of these contaminants in food and water at levels 25 times the ambient levels in plankton and water in Lake Michigan. The observed effect of the contaminants was...

Joan H. Fellers, Gary M. Fellers
1981, Technical Report CPSU/UH 40
The Crater District of Haleakala National Park was surveyed for ants. Three species were found. Argentine ants (Iridomyrmex humilis) occurred only within I km of the park headquarters and the nearby research facility. Hypoponera opaciceps was found in small numbers throughout the Crater District. Cardiocondyla emeryi was present only at...
