Fugacity of H2O from 0° to 350°C at the liquid-vapor equilibrium and at 1 atmosphere
John L. Hass Jr.
1970, Geochimica et Cosmochimica Acta (34) 929-932
The fugacity and fugacity coefficient of H2O at the liquid-vapor equilibrium, the fugacity and the Gibbs free energy of formation of H2O at 1 atm (1.01325 bars) total pressure have been calculated from published data on the physical and thermodynamic properties of H2O and are presented at ten-degree intervals from...
Chemotherapy of fish diseases: A review
R. L. Herman
1970, Journal of Wildlife Diseases (6) 31-34
Fish suffer from environmental, nutritional, viral, bacterial, parasitic, and neoplastic diseases, many of which are similar to those of higher animals. The prevention and treatment of these diseases follow the same principles as diseases of other animals. Fish culture is similar to poultry husbandry in that large numbers of animals...

Let's Sing 'Auld Lang Syne' for the Upper Brandywine: Or, to continue with Burns, how the best laid environmental schemes of men "gang aft a-gley"
Luna Bergere Leopold
1970, Natural History (79) 5-15
Perhaps the most lamentable mistake that one can make is to be right too soon. This was the story of the Brandywine Plan, an attempt to organize local people for the permanent protection of the environmental amenities of their own land.The Upper East Branch of Brandywine Creek drains a rolling...
GLC determination of quinaldine residue in fish
J. L. Allen, J.B. Sills
1970, Journal of the Association of Official Analytical Chemists (53) 20-23
A procedure for the determination of quinaldine residue in various fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether, the extracts are concentrated by partitioning through 0.1N sulfuric acid, and the residues are measured by alkali flame ionization gas chromatography. Muscle tissues containing from 0.01 to 10.0 ppm quinaldine...
Summer foods of lesser scaup in subarctic taiga
James C. Bartonek, H. W. Murdy
1970, Arctic (23) 35-44
Reports on the food of 25 adult and 38 juvenile Aythya affinis, collected in June-Sept 1967 along the Yellowknife Highway north of Great Slave Lake. The vegetation, physiography and ponds of the area, the collecting and statistical methods are briefly described. Approx 99% of the scaup diet was animal material; juveniles...
UV identification and quantitative measurement of quinaldine residues in fish
J. L. Allen, J.B. Sills
1970, Journal of the Association of Official Analytical Chemists (53) 1170-1171
A method for the confirmatory analysis of quinaldine residue in fish is described. The method utilizes the same extraction and cleanup procedure as the GLC method reported previously. The lower limit of sensitivity for quinaldine residue in fish muscle is 0.01 ppm. Identification is accomplished by comparing the UV spectra...
The determination of low levels of cobalt-60 in environmental waters by liquid scintillation counting
H.C. Claassen
1970, Analytica Chimica Acta (52) 229-235
A method for determination of cobalt-60 in waters at levels greater than 0.5 pCi per sample is presented. A modification of the method may be used to analyze fluvial sediments and soils. After the cobalt has been separated, first as the hydroxide and then as...
Occurrence of whirling disease of trout in western United States
H. Wolf, W. T. Yasutake
1970, Journal of the Fisheries Research Board of Canada (27) 955-956
Whirling disease of trout, caused by Myxosoma cerebralis, was diagnosed in 1966 for the first time in rainbow trout (Salmo gairdneri) from California and Nevada hatcheries. In 1969 the first incidence of this disease in cutthroat trout (S. clarki) was reported in Nevada. To date these have been the only confirmed cases...
Winds over saltcedar
T. E. A. Van Hylckama
1970, Agricultural Meteorology (7) 217-233
An analysis of hourly wind speeds above and within a stand of saltcedar near Buckeye, Arizona, reveals that in 90% of all observed cases, the wind profiles above the stand can be represented by the simple logarithmic equation: uz=u*k1n">uz=u*k1n (zz0)">zz0) where...
Static and kinetic friction of granite at high normal stress
J.D. Byerlee
1970, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (7) 577-582
Frictional sliding on ground surfaces of granite, angle of sliding planes 30° and 45°, was investigated as a function of confining pressure. Over the normal stress range of 2–12 kb, the static frictional shear stress τs follows the relationship τs = 0·5 + 0· σn and the kinetic frictional...
Major Land Resource Areas (MLRA)
Adapted from U.S. Soil Conservation Service
1970, Report
This is a polygon coverage of the Land Resource Regions and Major Land Resource Areas of the conterminous United States. Land resource regions are geographic areas that are characterized by a particular pattern of soils, climate, water resources and land uses. (USDA, Soil Conservation Service, 1981). Major land...

Trends in fishery management of the Great Lakes
Stanford H. Smith
1970, Special Publication 7
Some hope is returning for recovery of the fish stocks of the Great Lakes, which have been outstanding examples of abuse although they are the world's largest and most valuable freshwater fishery resource. The lakes and the fish in them have been under complete jurisdiction of sovereign nations and...

Significance of an aeromagnetic anomaly in the southwestern part of the Blue Range primitive area, Arizona-New Mexico
Gordon P. Eaton, James Clifford Ratte
1970, Open-File Report 69-84
In the Autumn of 1968 the U.S. Geological Survey flew a detailed aerial magnetic survey of the southwesternmost part of the Blue Range primitive area between Lat 33°21'00" and 33°29'00" N. and Long 109°15'00" and 109°22'30" W. The survey was intended to define more precisely a positive magnetic anomaly that...
