Movement of underyearling walleyes in response to odor and visual cues
D. V. Rottiers, C. A. Lemm
1985, Progressive Fish-Culturist (47) 34-41
Underyearling walleyes, allowed to move freely in a Y‐shaped chamber into which various substances were added to one arm or another, were attracted to sodium chloride, sucrose, glutathione, vitamin B12, betaine, arginine, Daphnia slurries, some fish slurries, washings from live Daphnia and Artemia, and some commercial fish foods. They avoided...
Immune response of channel catfish, Ictalurus punctatus Rafinesque, to bacterial and protozoan antigens administered by three routes
S. W. Pyle, D. L. Dawe
1985, Aquaculture (46) 1-10
Experiments were conducted to measure the agglutinating antibody response of channel catfish to a particulate and a soluble antigen administered simultaneously by one of three routes. Specific antibody production in response to administration of particulate brucella tube-test antigen via intramuscular injection, oral drench, and topical application peaked at 3 weeks...
Comparative sensitivities of diagnostic procedures used to detect bacterial kidney disease in salmonid fishes
R. C. Cipriano, C. E. Starliper, J. H. Schachte
1985, Journal of Wildlife Diseases (21) 144-148
Kidney and spleen homogenates from each of 60 coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri) were examined for detection of Renibacterium salmoninarum. The proportions of positives differed widely with the detection procedures used: in coho salmon, 5% were positive by the Gram-stain...

A procedure for estimating Bacillus cereus spores in soil and stream-sediment samples — A potential exploration technique
J.R. Watterson
1985, Journal of Geochemical Exploration (23) 243-252
The presence of bacterial spores of the Bacillus cereus group in soils and stream sediments appears to be a sensitive indicator of several types of concealed mineral deposits, including vein-type gold deposits. The B. cereus assay is rapid, inexpensive, and inherently reproducible. The test, currently under investigation for its potential in mineral...
The transverse and oblique cylindrical equal-area projection of the ellipsoid.
J.P. Snyder
1985, Annals of the Association of American Geographers (75) 431-442
The formulas for the ellipsoidal projection are derived for both forward and inverse computations and consist of modifying the formulas obtained by using the authalic sphere so that the scale along the central line of the projection is constant. Fourier series are used to eliminate recurring numerical integration and other...

V.E. McGee, N.M. Johnson, C. W. Naeser
1985, Nuclear Tracks and Radiation Measurements (1982) (10) 365-379
A computer program (FTD-SIM) faithfully simulates the fissioning of 238U with time and 235U with neutron dose. The simulation is based on first principles of physics where the fissioning of 238U with the flux of time is described by Ns = ??f 238Ut and the fissioning of 235U with the...
Scarp degraded by linear diffusion: Inverse solution for age
D.J. Andrews, Thomas C. Hanks
1985, Journal of Geophysical Research Solid Earth (90) 10193-10208
Under the assumption that landforms unaffected by drainage channels are degraded according to the linear diffusion equation, a procedure is developed to invert a scarp profile to find its “diffusion age.” Diffusion age, having dimension [length]2, is the product of diffusivity times chronological age. The second moment of scarp slope...
APPLICATIONS OF BOREHOLE-ACOUSTIC METHODS IN ROCK MECHANICS.
Frederick L. Paillet
1985, Conference Paper, Proceedings - Symposium on Rock Mechanics
Acoustic-logging methods using a considerable range of wavelengths and frequencies have proven very useful in the in situ characterization of deeply buried crystalline rocks. Seismic velocities are useful in investigating the moduli of unfractured rock, and in producing a continuous record of rock quality for comparison with discontinuous intervals of...

Time scales of change in the San Francisco Bay benthos
F.H. Nichols, J.K. Thompson
1985, Hydrobiologia (129) 121-138
Results from multi-year investigations in the San Francisco Bay estuary show that large abundance fluctuations within benthic macroinvertebrate populations reflect both (1) within-year periodicity of reproduction, recruitment, and mortality that is not necessarily coincident with seasonal changes of the environment (e.g., the annual temperature cycle), and (2) aperiodic density changes...

1985, Economic Geology (80) 2213-2229
The West Shasta copper-zinc district, Shasta County, California, contains many volcanogenic sulfide deposits within Middle Devonian rhyolites that have not been highly metamorphosed. The district was selected by the U.S. Geological Survey for intensive geological, geochemical, and geophysical study under the Development of Assessment Techniques (DAT) project because accessible exposures...

BORATE DEPOSITS IN THE UNITED STATES: DISSIMILAR IN FORM, SIMILAR IN GEOLOGIC SETTING.
George I. Smith
Barker James M.Lefond Stanley J., editor(s)
1985, Conference Paper
Borate deposits in the western United States have several geologic characteristics in common: All primary deposits are about 20 my or less in age, and they are observed or inferred to be stratigraphically associated with volcanic activity and thermal springs. Most of them lie at least partially in the lacustrine...

T. S. Collett
1985, Conference Paper, Society of Petroleum Engineers of AIME, (Paper) SPE
In 1973, during the drilling of the West Sak #1 well on the North Slope of Alaska, oil was first recovered from a shallow Cretaceous sand interval which was later informally named the West Sak sands by ARCO Alaska. Stratigraphically above the West Sak sands there are two additional oil...
CONCEPTUAL FRAMEWORK FOR REGRESSION MODELING OF GROUND-WATER FLOW.
Richard L. Cooley
1985, Conference Paper
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for modeling actual (as distinguished from hypothetical) systems. Finally, he examines the conceptual basis and characteristics of the regression approach to modeling ground-water flow....
Element mobility during alteration of silicic ash to kaolinite - A study of tonstein
R. A. Zielinski
1985, Sedimentology (32) 567-579
A laterally persistent kaolinitic mudstone parting (tonstein) occurring in a Wyoming coal bed of Eocene age was sampled to estimate the compositional contrast with a probable silicic ash precursor, and to determine the compositional influence of leached ash on immediately adjacent coal. With the exception of Al, and possibly Ti,...

1985, Conference Paper, Oceans Conference Record (IEEE)
The authors describe the conversion of an Endeco-174 current meter to a solid-state recording current meter. A removable solid-state module was designed to fit in the space originally occupied by an 8-track tape cartridge. The module contains a CPU and 128 kilobytes of nonvolatile CMOS memory. The solid-state module communicates...

1985, American Association of Petroleum Geologists Bulletin (69) 1275-1294
Common-depth-point (CDP) seismic reflection data in the southwestern Bahamas reveal the northern edge of the tectonized zone that resulted from the late Mesozoic-early Cenozoic collision of Cuba and the Bahamas. Two seismic facies are present: a basin facies and a shallow-water carbonate-platform facies. In Santaren Channel, between Cay Sal and...

Keith E. Bobay, Konrad J. Banaszak
Graves Donald H., editor(s)
1985, Conference Paper, University of Kentucky, Office of Engineering Services, (Bulletin) UKY BU
Two U. S. Geological Survey computer programs are modified and linked to predict the cumulative impact of iron and manganese oxidation in coal-mine discharge on the dissolved-chemical quality of a receiving stream. The coupled programs calculate the changes in dissolved-iron, dissolved-manganese, and dissolved-oxygen concentrations, and the pH of surface water...
Vp/Vs ratios in the Yellowstone National Park region, Wyoming
S.N. Chatterjee, A.D. Pitt, H. M. Iyer
1985, Journal of Volcanology and Geothermal Research (26) 213-230
In this paper we study the variation of Vp/Vs and Poisson's ratio (??) in the Yellowstone National Park region, using earthquakes which were well recorded by a local seismic network. We find that the average Vp/Vs value within the geothermally active Yellowstone caldera is about 7% lower than in the...
