Obstacles facing the venus radar mapper - The implications of gestalt formation in stereo-radargrammetry
R.L. Wildey
1986, Earth, Moon and Planets (35) 47-54
The question of adapting to radar images the existing hardware that form topographic maps through stereo-photogrammetric models, is examined in principle. Such hardware utilizes a human/ computer hybrid. Although the problem of brightness differentials between corresponding landmarks can be dealt with pseudo-photoclinometrically, the main problem is whether the perspective in...
The problem of complex eigensystems in the semianalytical solution for advancement of time in solute transport simulations: a new method using real arithmetic
Amjad M.J. Umari, Steven M. Gorelick
1986, Water Resources Research (22) 1149-1154
In the numerical modeling of groundwater solute transport, explicit solutions may be obtained for the concentration field at any future time without computing concentrations at intermediate times. The spatial variables are discretized and time is left continuous in the governing differential equation. These semianalytical solutions have been presented in the...
PERSPECTIVE ON LANDSLIDE DAMS.
Robert L. Schuster, John E. Costa
Schuster Robert L., editor(s)
1986, Conference Paper
The most common types of mass movements that form landslide dams are rock and soil slumps and slides; mud, debris, and earth flows: and rock and debris avalanches. The most common initiation mechanisms for dam-forming landslides are excessive rainfall and snow melt, and earthquakes. Most landslide dams are remarkable short-lived....

Tissue distribution and elimination of radiolabelled methyltestosterone fed to sexually undifferentiated blue tilapia
C. A. Goudie, W. L. Shelton, N. C. Parker
1986, Aquaculture (58) 215-226
Populations of monosex male Oreochromis aureus can result when the synthetic androgen 17α-methyltestosterone (MT) is fed to sexually undifferentiated fish; however, concerns exist over residues of the androgen remaining in fish destined for human consumption. Radioactivity in the carcass and viscera was evaluated in juvenile fish fed steroid-incorporated diet (tritium and carbon-14...
Tissue distribution and elimination of radiolabelled methyltestosterone fed to adult blue tilapia
C. A. Goudie, W. L. Shelton, N. C. Parker
1986, Aquaculture (58) 227-240
Radioactivity levels in 10 tissues were monitored for 21 days after adult (1-year-old) blue tilapia, Oreochromis aureus, were fed a single meal of a diet containing 30 μg unlabelled methyltestosterone (MT) per gram of feed and radiolabelled MT (3H-labelled steroid nucleus and 14C-labelled...

Strategies for reducing risks from introductions of aquatic organisms: The federal perspective
James P. Clugston
1986, Fisheries (11) 26-29
The Lacey Act of 1900 and subsequent amendments have provided the basis for existing federal regulations on species introductions. The 1981 version repealed the Black Bass Act and corrected certain insufficiencies in the original Lacey and Black Bass Acts. A 1977 executive order instructs federal agencies, to the extent permitted...

Urea cycle activity and arginine formation in rainbow trout (Salmo gairdneri)
Y. N. Chiu, R. E. Austic, G. L. Rumsey
1986, Journal of Nutrition (116) 1640-1650
Studies were conducted to determine whether rainbow trout fingerlings possess the ability to synthesize arginine via the urea cycle. Several urea cycle enzymes were detected in trout tissues. An experiment was conducted to determine whether the enzymes increase in response to starvation or in response to dietary protein level (0,...
Review of the intensive culture of walleye fry
W. F. Krise, J. W. Meade
1986, Progressive Fish-Culturist (48) 81-89
Efficient intensive culture of larval walleyes (Stizostedion vitreum) may soon be realized due to results of research on larval development, culture environment, preferred food organisms, and feeding techniques. Larval behavior and morphology (developmental state) can be used as indicators for appropriate handling and feeding techniques. Certain environmental conditions such as...
Selenium and heavy metals in San Francisco Bay diving ducks
Harry M. Ohlendorf, Roy W. Lowe, Paul R. Kelly, Thomas E. Harvey
1986, Journal of Wildlife Management (50) 64-70
We analyzed for selenium (Se) and heavy metals in greater scaups (Aythya marila) and surf scoters (Melanitta perspicillata) collected from southern San Francisco Bay in March and April 1982. There were no differences (P > 0.05) between species for liver concentrations of silver (Ag), mercury (Hg), or lead (Pb). Copper...

Z. C. Peng, R. E. Zartman, K. Futa, D.G. Chen
1986, Chemical Geology (59) 3-33
Forty-eight Paleogene, Neogene and Quaternary basaltic rocks from northeastern and east-central China have been analyzed for major-element composition, selected trace-element contents, and Pb, Sr and Nd isotopic systematics. The study area lies entirely within the marginal Pacific tectonic domain. Proceeding east to...
Isotope geochemistry of recent magmatism in the Aegean arc: Sr, Nd, Hf, and O isotopic ratios in the lavas of Milos and Santorini-geodynamic implications
L. Briqueu, M. Javoy, J.R. Lancelot, M. Tatsumoto
1986, Earth and Planetary Science Letters (80) 41-54
In this comparative study of variations in the isotopic compositions (Sr, Nd, O and Hf) of the calc-alkaline magmas of the largest two volcanoes, Milos and Santorini, of the Aegean arc (eastern Mediterranean) we demonstrate the complexity of the processes governing the evolution of the magmas on the scale both...
Immunoblot assay: a rapid and sensitive method for identification of salmonid fish viruses
P. E. McAllister, W. B. Schill
1986, Journal of Wildlife Diseases (22) 468-474
An immunoblot assay was used to identify the viruses of infectious pancreatic necrosis, infectious hematopoietic necrosis, and viral hemorrhagic septicemia. Viral antigen in infected cell culture supernatant was adsorbed onto nitrocellulose membrane or Whatman 541 filter paper and detected by enzyme-linked immunosorbent assay...

R.F. Madole
1986, Quaternary Research (25) 43-54
Glacial Lake Devlin was an ice-margin lake that formed during Pinedale time when the North Boulder Creek valley glacier blocked the mouth of a tributary near the downvalley limit of glaciation. The lake was about 2 km long and as much as 60 m deep, and was fed by meltwater...

1986, IEEE Transactions on Geoscience and Remote Sensing (GE-24) 603-623
SIR-A signal penetration and subsurface backscatter within the upper meter or so of the sediment blanket in the Eastern Sahara of southern Egypt and northern Sudan are enhanced both by radar sensor parameters and by the physical and chemical characteristics of eolian and alluvial materials. Interpretation of SIR-A images by...

Ground-water resource assessment of the Montauk area, Long Island, New York
K. R. Prince
1986, Water-Resources Investigations Report 85-4013
The water resources of the Montauk area were investigated from October 1980 through September 1983 to assess the availability of fresh groundwater. The principal aquifer, which consists of fine- to coarse-grained stratified glacial drift, is the sole source of freshwater. The freshwater/saltwater interface lies as much as 150 ft below...
A case study of soil gases as an exploration guide in glaciated terrain: Crandon massive sulfide deposit, Wisconsin
J. Howard McCarthy, R. N. Lambe, John A. Dietrich
1986, Economic Geology (81) 408-420
The Crandon massive sulfide deposit is covered by as much as 65 m of glacial drift. Soil gas was sampled at a depth of 0.5 m along several traverses over the deposit. Gases showing anomalies that correlate with the underlying deposit include CO 2 , CH 4 , and O 2 . CO 2 and CH 4 show positive anomalies...

T. S. Hayes, M.T. Einaudi
1986, Economic Geology (81) 1899-1931
Mineable zones of the Spar Lake deposit occur where argentiferous copper sulfides and native silver formed cements and replaced certain earlier cements and clasts in the gently dipping middle quartzite beds of the upper member of the Revett Formation, middle Proterozoic Belt Supergroup. The copper sulfides and native silver are...
