A single crystal of untwinned orthopyroxene from lunar anorthosite sample 15415, with composition (Mg1.14Fe0.80Mn0.02Ca0.04)(Si1.97Al0.03)O6, has a unit cell in space groupPbca witha = 18.310(15)Å,b = 8.904(10)Å,c = 5.214(7)Å, containing 2 formula units. A set of 742 counter-measured intensity data made with MoKα radiation has been used to refine the crystal structure in isotropic thermal mode...
Determination of dissolved boron in fresh, estuarine, and geothermal waters by d.c. argon-plasma emission spectrometry
J.W. Ball, J. M. Thompson, Everett A. Jenne
1978, Analytica Chimica Acta (98) 67-75
A d.c. argon-plasma emission spectrometer is used to determine dissolved boron in natural (fresh and estuarine) water samples. Concentrations ranged from 0.02 to 250 mg l-1. The emission—concentration function is linear from 0.02 to 1000 mg l-1. Achievement of a relative standard deviation of ⩽ 3% requires frequent restandardization to...

E.M. Thurman, Ronald L. Malcolm, G. R. Aiken
1978, Analytical Chemistry (50) 775-779
The capacity factors of 20 aromatic, allphatic, and allcycllc organic solutes with carboxyl, hydroxyl, amine, and methyl functional groups were determined on Amberlite XAD-8, a porous acrylic resin. The logarithm of the capacity factor, k', correlated inversely with the logarithm of the aqueous molar solubility with significance of less than...

Biochemical identification of mallard-black duck hybrids through a breeding program and in nature
R.P. Morgan II, D. W. Meritt, S. B. Block, M. Cole
1978, Transactions of the Northeast Section of the Wildlife Society, Annual Fish and Wildlife Conference (35) 225-236
From 1974 to 1976, a breeding program was used to produce black duck-mallard hybrids for the evaluation of inheritance patterns of serum proteins and esterases. In addition to the initial crosses, a series of matings in 1975 and 1976 were designed to evaluate inheritance patterns in hybrid matings with either...
Waterfowl nesting on small man-made islands in prairie wetlands
R.F. Johnson Jr., R.O. Woodward, L.M. Kirsch
1978, Wildlife Society Bulletin (6) 240-243
Small islands constructed in prairie wetlands were attractive nesting sites for mallards (Anas platyrhynchos) and Canada geese (Branta canadensis). Nest densities of mallards on islands averaged 135 per ha compared to 0.03 per ha on adjacent upland habitats. Construction time averaged 2 hours per island and cost $50. No maintenance...
Analytical multicollimator camera calibration
W.P. Tayman
1978, Photogrammetria (34) 179-197
Calibration with the U.S. Geological survey multicollimator determines the calibrated focal length, the point of symmetry, the radial distortion referred to the point of symmetry, and the asymmetric characteristiecs of the camera lens. For this project, two cameras were calibrated, a Zeiss RMK A 15/23 and a Wild RC 8....
Environmental trade-offs of tunnels vs cut-and-cover subways
M. Walton
1978, Underground Space (3) 61-67
Heavy construction projects in cities entail two kinds of cost - internal cost, which can be defined in terms of payments from one set of parties to another, and external cost, which is the cost borne by the community at large as the result of disutilities entailed in construction and...
The moon: Composition determined by nebular processes
J. W. Morgan, J. Hertogen, E. Anders
1978, The Moon and the Planets (18) 465-478
The bulk composition of the Moon was determined by the conditions in the solar nebula during its formation, and may be quantitatively estimated from the premise that the terrestrial planets were formed by cosmochemical processes similar to those recorded in the chondrites. The calculations are based on the Ganapathy-Anders 7-component...
Myxosoma cerebralis: Detection of circulating antibodies in infected rainbow trout (Salmo gairdneri)
B.R. Griffin, E.M. Davis
1978, Journal of the Fisheries Research Board of Canada (35) 1186-1190
Circulating antibody against spores of Myxosoma cerebralis has been detected for the first time in rainbow trout (Salmo gairdneri) affected with whirling disease. An indirect fluorescent antibody test (IFAT) was employed for detection of trout immunoglobulin. Most sera of fish from an infected experimental group were found to give a positive reaction...

Revised values for the Gibbs free energy of formation of [Al(OH)4 aq-], diaspore, boehmite and bayerite at 298.15 K and 1 bar, the thermodynamic properties of kaolinite to 800 K and 1 bar, and the heats of solution of several gibbsite samples
B. S. Hemingway, R. A. Robie, J.A. Kittrick
1978, Geochimica et Cosmochimica Acta (42) 1533-1543
Solution calorimetric measurements compared with solubility determinations from the literature for the same samples of gibbsite have provided a direct thermochemical cycle through which the Gibbs free energy of formation of [Al(OH)4 aq−] can be determined. The Gibbs free energy of formation of [Al(OH)4 aq−] at 298.15 K is −1305...

W. Sullivan
1978, Earthquake Information Bulletin (USGS) (10) 160-161
To minimize damage and loss of life when, as is believed inevitable, a major earthquake strikes the United States, plans have been prepared for the creation of new Federal agencies, widespread reinforcement of structures and extensive research on earthquake prediction, control, and hazard reduction. ...
Malic acid accumulation in roots in response to flooding: Evidence contrary to its role as an alternative to ethanol
Jon E. Keeley
1978, Journal of Experimental Botany (29) 1345-1349
Across a time course of flooding the malic acid content in roots of the swamp tree Nyssa sylvatica var. biflora increased 5-fold from 1 week to 1 month of flooding and remained at that level through a full year of flooding. Alcoholic fermentation rates accelerated within the first month of flooding but dropped to...
Evaluation of an aerial survey of Pacific walruses
J. A. Estes, James R. Gilbert
1978, Journal of the Fisheries Research Board of Canada (35) 1130-1140
An aerial survey of Pacific walruses (Odobenus rosmarus divergens) was evaluated to determine the reliability of estimates of population abundance. The probability of detecting groups of walruses on the pack ice remained uniform to at least 0.93 km from the flight line, whereas the probability of detection decreased significantly beyond 0.23 km...
Sea otter predation and community organization in the western Aleutian Island, Alaska
J. E. Estes, N. S. Smith, J. F. Palmisano
1978, Ecology (59) 822-833
Predation by the sea otter (Enhydra lutris) limits epibenthic invertebrates, especially sea urchins (Strongylocentrotus polyacanthus), in turn allowing a luxuriant development of the macroalgal canopy. Where sea otters are abundant, sea urchins are small and scarce in shallow water, and the association of fleshy macroalgae apparently is regulated by competition....
Radon emanation on the San Andreas Fault
C. Y. King
1978, Earthquake Information Bulletin (USGS) (10) 136-138
Radon is a radioactive gas with a half-life of 3.8 days. (Half-life is the time required for the substance to lose half of its radioactivity by decay.) It is itself produced by the decay of uranium. Radon is constantly emanated from the Earth into the atmosphere. Many cases are known...
Prevention and treatment of Nitrite toxicity in juvenile steelhead trout (Salmo gairdneri)
Gary A. Wedemeyer, W. T. Yasutake
1978, Journal of the Fisheries Research Board of Canada (35) 822-827
The efficacy of mineral salts, pH, and tetramethylthianine (methylene blue) treatment in reducing the acute toxicity of nitrite to fingerling steelhead trout (Salmo gairdneri) was determined using a static bioassay system at 10 °C. The acute toxicity (96-h LC50) was reduced by a factor of about 24 for 5-g steelhead...
New potassium-argon data on the age of mineralization and metamorphism in the Willow Creek mining district, southern Talkeetna Mountains, Alaska
Miles L. Silberman, Bela Csejtey Jr., James G. Smith, Marvin A. Lanphere, Frederic H. Wilson
1978, Circular 772-B
The now largely abandoned Willow Creek mining district, southern Talkeetna Mountains, Alaska, produced nearly $18,000,000 in gold and minor silver between 1909 and the early 1950's. Mineralized quartz veins, which contain gold and silver along with minor quantities of base metals (in pyrite, galena, chalcopyrite, sphalerite, molybdenite, and arsenopyrite), cut...
Heritability of tolerance for infectious hematopoietic necrosis in sockeye salmon (Oncorhynchus nerka)
John D. McIntyre, Donald F. Amend
1978, Transactions of the American Fisheries Society (107) 305-308
A hierarchical breeding design was used to demonstrate the heritability of tolerance for infectious hematopoietic necrosis (IHN) in sockeye salmon. Oncorhynchus nerka. Heritability was about 30%, indicating that artificial selection may increase the number of fish that can tolerate the disease....
