Seasonal changes in cortisol sensitivity and glucocorticoid receptor affinity and number in leukocytes of coho salmon
Alec G. Maule, Carl B. Schreck, Cameron Sharpe
1993, Fish Physiology and Biochemistry (10) 497-506
To determine if there were organ-specific changes in immune responses or immune-endocrine interaction, we monitored in vitro immune response, cortisol sensitivity and number and affinity of glucocorticoid receptors (GR) in leukocytes from freshwater-adapted juvenile coho salmon (Oncorhynchus kisutch) during the physiological changes that prepare them to...

1993, Archives of Environmental Contamination and Toxicology (24) 345-354
The environment has become contaminated with complex mixtures of planar, chlorinated hydrocarbons (PCHs) such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and structurally similar compounds. Because the potencies of individual congeners to cause the same adverse effects vary greatly and the relative as well...

Toxicity and bioaccumulation of waterborne and dietary selenium in juvenile bluegill (Lepomis macrochirus)
Laverne Cleveland, Edward E. Little, Denny R. Buckler, Raymond H. Wiedmeyer
1993, Aquatic Toxicology (27) 265-279
Juvenile bluegill (Lepomis macrochirus) were exposed to waterborne selenium as a 6:1 mixture of selenate to selenite (as Se) for 60 d and to dietary seleno-l-methionine for 90 d. Measured concentrations of total selenium in the waterborne exposure ranged from 0.16 to 2.8 mg/l, and concentrations of seleno-l-methionine...

Shen Hsieh WenSu S.T.Wen Feng, editor(s)
1993, Conference Paper, Proceedings - National Conference on Hydraulic Engineering
A time-dependent, three-dimensional numerical modeling study of the tides of Massachusetts and Cape Code Bays, motivated by construction of a new sewage treatment plant and ocean outfall for the city of Boston, has been undertaken by the authors. The numerical model being used is a hybrid version of the Blumberg...
Directions of the US Geological Survey Landslide Hazards Reduction Program

1993, Geografia Fisica e Dinamica Quaternaria (16) 21-25
The US Geological Survey (USGS) Landslide Hazards Reduction Program includes studies of landslide process and prediction, landslide susceptibility and risk mapping, landslide recurrence and slope evolution, and research application and technology transfer. Studies of landslide processes have been recently conducted in Virginia, Utah, California, Alaska, and Hawaii, Landslide susceptibility maps...
Pressure increases, the formation of chromite seams, and the development of the ultramafic series in the Stillwater Complex, Montana
Bruce R. Lipin
1993, Journal of Petrology (34) 955-976
This paper explores the hypothesis that chromite seams in the Stillwater Complex formed in response to periodic increases in total pressure in the chamber. Total pressure increased because of the positive δV of nucleation of CO2 bubbles in the melt and their subsequent rise through the magma chamber, during which...
Culvert analysis program for indirect measurement of discharge
Janice M. Fulford
Shen Hsieh WenSu S.T.Wen Feng, editor(s)
1993, Conference Paper, Proceedings - National Conference on Hydraulic Engineering
A program based on the U.S. Geological Survey (USGS) methods for indirectly computing peak discharges through culverts allows users to employ input data formats used by the water surface profile program (WSPRO). The program can be used to compute discharge rating surfaces or curves that describe the behavior of flow...
Nonpoint source contamination of the Mississippi river and its tributaries by herbicides
W. E. Pereira, F. D. Hostettler
1993, Environmental Science & Technology (27) 1542-1552
A study of the Mississippi River and its tributaries during July-August 1991, October-November 1991, and April-May 1992 has indicated that the entire navigable reach of the river is contaminated with a complex mixture of agrochemicals and their transformation products derived from nonpoint sources. Twenty-three compounds were identified, including triazine, chloroacetanilide,...
Climatic impact on isovolumetric weathering of a coarse-grained schist in the northern Piedmont Province of the central Atlantic states
E.T. Cleaves
1993, Geomorphology (8) 191-198
The possible impact of periglacial climates on the rate of chemical weathering of a coarse-grained plagioclase-muscovite-quartz schist has been determined for a small watershed near Baltimore, Maryland. The isovolumetric chemical weathering model formulated from the geochemical mass balance study of the watershed...
Thortveitite and associated Sc-bearing minerals from Ravalli County, Montana

1993, Canadian Mineralogist (31) 337-346
The rare Sc mineral thortveitite, (Sc,Y)2Si2O7, occurs as ??m- to mm-sized crystals in fluorite-bearing granitic pegmatites and the host melagabbro within the Crystal Mountain fluorite deposit, Ravalli County, Montana. Thortveitite is found as colorless and clear to smoky and translucent, subhedral to euhedral prisms up to 3 mm in length...
The pyramid system for multiscale raster analysis
L. De Cola, N. Montagne

Geographical research requires the management and analysis of spatial data at multiple scales. As part of the U.S. Geological Survey's global change research program a software system has been developed that reads raster data (such as an image or digital elevation model) and produces a pyramid of aggregated lattices as...

Anon, editor(s)
1993, Conference Paper, Transactions - Geothermal Resources Council
In November 1992 the valve at the top of a U.S. Geological Survey drill hole in Yellowstone National Park parted from the casting as a result of corrosion. This allowed uncontrolled venting of boiling water and steam from the well at an estimated liquid flow rate of about 25-50 gallons...
Courant number and unsteady flow computation
Chintu Lai
Shen Hsieh WenSu S.T.Wen Feng, editor(s)
1993, Conference Paper, Proceedings - National Conference on Hydraulic Engineering
The Courant number C, the key to unsteady flow computation, is a ratio of physical wave velocity, ??, to computational signal-transmission velocity, ??, i.e., C = ??/??. In this way, it uniquely relates a physical quantity to a mathematical quantity. Because most unsteady open-channel flows are describable by a set...
An algal carbon budget for pelagic-benthic coupling in Lake Michigan
S.A. Fitzgerald, W.S. Gardner
1993, Limnology and Oceanography (38) 547-560
Assimilation and respiration rates of Diporeia sp., an abundant benthic amphipod, and of sediment microheterotrophs were measured in a microcosm study. Release of radioisotope in the form of dissolved organic compounds was much lower than that incorporated and respired for both Diporeia and sediment bacteria. Of the 61 mmol C...
Petrology and U-Pb geochronology of buried Avalonian plutonic rocks on southeastern Cape Cod
G. W. Leo, J.K. Mortensen, B. Barreiro, J. D. Phillips
1993, Atlantic Geology (29) 103-113
Plutonic rocks have been intersected by two separate drill holes on southeastern Cape Cod. Hole CC2 is located at Chatham Harbor about 7 km south of the Nauset anomaly, an east-northeast-trending magnetic lineament that was considered to separate the distinct plutonic zones of Avalon terrane. This drill hole intersected weakly...
Regional flow in the Baltic Shield during Holocene coastal regression
Clifford I. Voss, Johan Andersson
1993, Groundwater (31) 989-1006
The occurrence of saline waters in the Baltic Shield in Sweden is consistent with ongoing but incomplete Holocene flushing and depends on the geometry and connectivity of conductive structures at both regional and local scales, and on the surface topography. Numerical simulation of regional...

M.J. Baedecker, I.M. Cozzarelli, R.P. Eganhouse, D. I. Siegel, P.C. Bennett
1993, Applied Geochemistry (8) 569-586
Crude oil floating on the water table in a sand and gravel aquifer provides a constant source of hydrocarbons to the groundwater at a site near Bemidji, Minnesota. The degradation of hydrocarbons affects the concentrations of oxidized and reduced aqueous species in the anoxic part of the contaminant plume that...
