Some aspects of breeding biology of the blue-winged teal
C.W. Dane
1966, The Auk (83) 389-402
The Blue-winged Teal (Anas discors) was the subject of one of the first publications dealing with the breeding biology of a species of North American waterfowl (Bennett, 1938). Recent studies of the nesting chronology, clutch size, and incubation period of this species include the works of Hochbaum (1944), Sowls (1955),...

Some effects of Heptachlor on bluegills (Lepomis macrochirus)
Austin K. Andrews, Bruce E. Stebbings, Charles C. Van Valin
1966, Transactions of the American Fisheries Society (95) 297-309
In complementary studies of the chronic effects of heptachlor on bluegills, four similar earthen ponds were treated once with different concentrations of heptachlor, and the fish in six plastic pools were routinely fed different levels of heptachlor. A fifth pond and two plastic pools were used as controls. Higher dosages...
Some Debye temperatures from single-crystal elastic constant data
R. A. Robie, J.L. Edwards
1966, Journal of Applied Physics (37) 2659-2663
The mean velocity of sound has been calculated for 14 crystalline solids by using the best recent values of their single‐crystal elastic stiffness constants. These mean sound velocities have been used to obtain the elastic Debye temperatures θDe for these materials. Models of the three wave velocity surfaces for calcite are illustrated....
Crystallization of tholeiitic basalt in Alae Lava Lake, Hawaii
D. L. Peck, T. L. Wright, J.G. Moore
1966, Bulletin Volcanologique (29) 629-655
The eruption of Kilauea Volcano August 21–23, 1963, left 600,000 cubic meters of basaltic lava in a lava lake as much as 15 meters deep in Alae pit crater. Field studies of the lake began August 27 and include repeated core drilling, measurements of temperature in the crust and melt,...
Oxygen fugacities directly measured in magmatic gases
M. Sato, T. L. Wright
1966, Science (153) 1103-1105
An electrochemical device was used to measure the fugacity of oxygen (fO2) in holes drilled through the crust of Makaopuhi lava lake, Kilauea Volcano, Hawaii. Results obtained within 6 months of the lake formation show that log fO2 normally varies linearly with the reciprocal of the absolute temperature, and that...
Variational method of determining effective moduli of polycrystals with tetragonal symmetry
R. Meister, L. Peselnick
1966, Journal of Applied Physics (37) 4121-4125
Variational principles have been applied to aggregates of randomly oriented pure‐phase polycrystals having tetragonal symmetry. The bounds of the effective elastic moduli obtained in this way show a substantial improvement over the bounds obtained by means of the Voigt and Reuss assumptions. The Hill average is found to be a good approximation in...
Hydrologic and climatologic data collected through 1964, Salt Lake County, Utah
W.V. Iorns, Reed W. Mower, C. A. Horr
1966, Utah Basic-Data Release 11
An investigation of the water resources of Salt Lake County, Utah, was undertaken by the Water Resources Division of the U.S. Geological Survey in July 1963. This investigation is a cooperative project financed equally by the State of Utah and the Federal Government in accordance with an agreement between the...

Rare earths in phosphorites: Geochemistry and potential recovery
Z. S. Altschuler, Sol Berman, Frank Cuttitta
1966, Open-File Report 66-3
Rare earths are but trace constituents of marine apatite. However, as millions of tones of such apatite are dissolved annually to make phosphoric acid, an opportunity exists for greatly increasing RE output as by-product of fertilizer production. New, complete, quantitative analysis of RE in representative apatite concentrates reveal that the...
Uptake of 2,4-dichlorophenoxyacetic acid by Pseudomonas fluorescens
Gary Wedemeyer
1966, Applied and Environmental Microbiology (14) 486-491
Factors influencing the uptake of the sodium salt of 2,4-dichlorophenoxyacetic acid (2,4-D), under conditions in which no net metabolism occurred, were investigated in an effort to determine both the significance of “non-metabolic” uptake as a potential agent in reducing pesticide levels and the mechanisms involved. Uptake of 2,4-D was affected...
Toxicities of several pesticides to two species of Cladocerans
Herman O. Sanders, Oliver B. Cope
1966, Transactions of the American Fisheries Society (95) 165-169
Laboratory bioassays were conducted with some chlorinated hydrocarbon insecticides, organophosphate insecticides, other insecticides and acaricides, and with herbicides to determine their relative toxicities and immobilization values for two species of daphnids, Daphnia pulex and Simocephalus serrulatus. Both species are satisfactory bioassay organisms for the determination of a wide variety...
Persistence of 2,6-Dichlorobenzonitrile in aquatic environments
C.C. Van Valin
1966, Book chapter, Organic pesticides in the environment
In two experiments 2,6-dichlorobenzonitrile was added to aquatic systems, and the residue levels were followed for about 6 months. A granular formulation applied to a farm pond at 0.6 p.p.m. produced highest residues in water and fish about 2 weeks following treatment whereas vegetation and soil samples had the highest...
River meanders
Luna Bergere Leopold, Walter Basil Langbein
1966, Scientific American 60-70
The striking geometric regularity of a winding river is no accident. Meanders appear to be the form in which a river does the least work in turning; hence they are the most probable form a river can take...
Chemical composition of phosphorites of the Phosphoria Formation
R. A. Gulbrandsen
1966, Geochimica et Cosmochimica Acta (30) 769-778
The chemical composition, both major and minor constituents, of 60 samples of phosphorite from the Phosphoria Formation was determined. Major constituents of the average phosphorite are, by weight per cent: SiO2, 11·9; Al2O3, 1·7; Fe2O3,1·1; MgO, 0·3; CaO, 44·0; Na2O, 0·6; K2O, 0·5; total H2O, 2·2; H2O−, 0·6; TiO2, 0·1;...

Some blood chemistry values for five Chesapeake Bay area fishes
J. B. Hunn, P.F. Robinson
1966, Chesapeake Science (7) 173-175
Blood samples from gizzard shad,largemouth bass, white perch, pumpkinseed, and toadfish were analyzed for hemoglobin, total plasma protein, total plasma cholesterol, and ion concentrations of plasma sodium, potassium, and chloride. The hemoglobin concentration and total plasma cholesterol found in a given species seem to have positive correlation with the customary activity level...
Color variations within glacial till, east-central North Dakota--A preliminary investigation
T. E. Kelly, Claud H. Baker Jr.
1966, Journal of Sedimentary Petrology (36) 75-80
Color variations (orange zones within buff-colored till) in drift in east-central North Dakota are believed to represent two tills of separate origin. Mean size, standard deviation, and number and type of pebbles show greater difference between the two tills than do skewness, kurtosis, and partial chemical analyses. Probably blocks of...
