Radial particle-size segregation during packing of particulates into cylindrical containers
C.D. Ripple, R.V. James, J. Rubin
1973, Powder Technology (8) 165-175
In a series of experiments, soil materials were placed in long cylindrical containers, using various packing procedures. Soil columns produced by deposition and simultaneous vibratory compaction were dense and axially uniform, but showed significant radial segregation of particle sizes. Similar results were obtained with deposition and simultaneous impact-type compaction when...
Galerkin finite-element simulation of a geothermal reservoir
J.W. Mercer Jr., G.F. Pinder
1973, Geothermics (2) 81-89
The equations describing fluid flow and energy transport in a porous medium can be used to formulate a mathematical model capable of simulating the transient response of a hot-water geothermal reservoir. The resulting equations can be solved accurately and efficiently using a numerical...
Inorganic chemical investigation by x-ray fluorescence analysis: The Viking Mars Lander
P. Toulmin III, A. K. Baird, B. C. Clark, Klaus Keil, H. J. Rose Jr.
1973, Icarus (20) 153-178
The inorganic chemical investigation added in August 1972 to the Viking Lander scientific package will utilize an energy-dispersive X-ray fluorescence spectrometer in which four sealed, gas-filled proportional counters will detect X-rays emitted from samples of the Martian surface materials irradiated by X-rays from radioisotope sources (55Fe and 109Cd). The output...
The sorption of silver by poorly crystallized manganese oxides
B.J. Anderson, E. A. Jenne, T. T. Chao
1973, Geochimica et Cosmochimica Acta (37) 611-622
The sorption of silver by poorly crystallized manganese oxides was studied using synthesized samples of three members of the manganous manganite (birnessite) group, of different chemical composition and crystallinity, and a poorly organized γ-MnO2. All four oxides sorbed significant quantities of silver. The manganous manganites showed the greatest sorption (up...

E. Mazor, R.O. Fournier
1973, Geochimica et Cosmochimica Acta (37) 515-525
Water and gas samples from research wells in hydrothermal areas of Yellowstone National Park, U.S.A., have been mass spectrometrically analyzed for their rare gas contents and isotopic composition. In agreement with previous findings, the rare gases have been found to originate from infiltrating...
Toxicity of TFM (lampricide) to six early stages of rainbow trout (Salmo gairdneri)
L.E. Olson, L. L. Marking
1973, Journal of the Fisheries Research Board of Canada (30) 1047-1052
The lampricide TFM (3-trifluoromethyl-4-nitrophenol) was tested against the following life stages of rainbow trout (Salmo gairdneri): green eggs, eyed eggs, sac fry, swim-up fry, fry, and fingerlings in four water hardnesses (12, 44, 170, and 320 mg/liter as CaCO3). The eyed-egg stage was one of the most resistant stages tested, and...
87Sr/86Sr ratios in basalts from islands in the Indian Ocean
C. E. Hedge, N.D. Watkins, R.A. Hildreth, W. P. Doering
1973, Earth and Planetary Science Letters (21) 29-34
87Sr/86Sr ratios of basalts from islands in the Indian Ocean (0.7040) are higher than those of basalts dredged from the Mid-Indian Ocean Ridge (0.7034). The sources of the island basalts have apparently not been in equilibrium with the source of the...
Petrography and stratigraphy of glacial drift, Mesabi-Vermilion Iron Range area, northeastern Minnesota
Thomas C. Winter, R. D. Cotter, H. L. Young
1973, Bulletin 1331-C
Glacial deposits in the Mesabi-Vermilion Iron Range area consist of four major till units and associated glaciofluvial sediments. Particle-size data and pebble, heavy-mineral, clay-mineral, and percentage-soluble content were used in addition to field description of color and texture to describe and correlate the drift units. The lowermost till unit, basal till,...
Red sea drillings

1973, Science (179) 377-380
Recent drilling in the Red Sea has shown that much of the basin is underlain by evaporites of a similar age to that of evaporites found in the Mediterranean Sea. These evaporites and their structural positions indicate that other brine areas are present - and, indeed, several others have been...
Changes in the visual pigments of trout
D.M. Allen, W.N. McFarland, F.W. Munz, H. A. Poston
1973, Canadian Journal of Zoology (51) 901-914
The proportions of two visual pigments (rhodopsin and porphyropsin) were examined in four species of trout under experimental and natural conditions. Brook trout (Salvelinus fontinalis), rainbow trout (Salmo gairdneri), and brown trout (Salmo trutta) have different relative proportions of visual pigments in their retinae. The visual pigment balance in wild...

Biochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, August 1973
Wilbur C. Ballance
1973, Report
Radiochemical data from the Amchitka Island study area were obtained from water samples collected by the U.S. Geological Survey during August 1973. Tritium determinations were made on 86 samples collected and gross alpha and gross beta/gamma determinations were made on 38 samples. The range of data for these samples was...

1973, Report
The U.S. Geological Survey, in cooperation with the Texas Water Development Board, began hydrologic studies in the Austin urban area in 1954. The objectives of this project are as follows: 1. To determine the effects of progressive urbanization on infiltration, rates of peak discharge, and rainfall-runoff...

Alan B. Sargeant, George A. Swanson, Harold A. Doty
1973, American Midland Naturalist (89) 208-214
Predation by mink (Mustela vison) on three types of ducks (captive, pen-reared-released and wild) was documented in two studies at the Northern Prairie Wildlife Research Center, Jamestown, North Dakota. In the first study, 36 of 60 flightless adult and juvenile ducks held on eight 0.1-acre experimental ponds disappeared between 10...

Myxosoma cerebralis: Isolation and concentration from fish skeletal elements - Trypsin digestion method
M.L. Landolt
1973, Journal of the Fisheries Research Board of Canada (30) 1713-1716
An improved method for detection of Myxosoma cerebralis spores is described. Spores were freed from skeletal tissue by trypsin digestion and ether was used for purification of spore suspension. As compared to mechanical grinding, this procedure resulted in a sixfold increase in observable spores....
Some physiological aspects of sublethal heat stress in the juvenile steelhead trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch)
Gary Wedemeyer
1973, Journal of the Fisheries Research Board of Canada (30) 831-834
A rapid (3 min) but sublethal temperature increase from 10 to 20 imposed a greater stress on juvenile coho salmon (Oncorhynchus kisutch) than on juvenile steelhead trout (Salmo gairdneri). Both species suffered hyperglycemia, hypocholesterolemia, increased blood hemoglobin, and decreased blood sugar regulatory precision, but the steelhead recovered more quickly. Acid–base equilibrium...
Nutritional factors in the biochemical pathology of Corynebacterial kidney disease in the coho salmon (Oncorhynchus kisutch)
Gary A. Wedemeyer, A. J. Ross
1973, Journal of the Fisheries Research Board of Canada (30) 296-298
The influence of diet ingredient on the morbidity and biochemical pathogenesis of corynebacterial kidney disease was investigated using juvenile coho salmon (Oncorhynchus kisutch) fed the Abernathy dry ration made up with either corn gluten or cottonseed meal (isoprotein, isocaloric substitution). Evaluation of incidence of infection, pituitary activation and aspects of...
U-Th-Pb measurements of Luna 20 soil
M. Tatsumoto
1973, Geochimica et Cosmochimica Acta (37) 1079-1086
The concentrations of uranium, thorium and lead and the lead isotopic composition of Luna 20 soil were determined. The data indicate that the Luna 20 soil is mainly a mixture of highland anorthosites and low-K basalt, but little KREEP basalt. The U-Th-Pb systematics...
Uranium concentration and distribution in six peridotite inclusions of probable mantle origin
E.L. Haines, R. E. Zartman
1973, Earth and Planetary Science Letters (20) 45-53
Fission-track activation was used to investigate uranium concentration and distribution in peridotite inclusions in alkali basalt from six localities. Whole-rock uranium concentrations range from 24 to 82 ng/g (1ng= 10−9g). Most of the uranium is uniformly distributed in the major silicate phases...
