Disposition of 1-naphthol in the channel catfish (Ictalurus punctatus)
G. R. Stehly, S. M. Plakas
1992, Drug Metabolism and Disposition (20) 70-73
The pharmacokinetics, tissue distribution, and metabolism of 1-naphthol were examined in the channel catfish (Ictalurus punctatus ). After oral dosing, peak plasma concentrations of 1-naphthol occurred at 1 hr; parent compound made up less than 15% of the total radioactivity, and the bioavailability was 32%. Plasma protein...
Hydraulic roughness of earth covers at a cold-desert waste burial site
B.F. Goff, G.C. Bent, G.E. Hart
1992, Arid Soil Research and Rehabilitation (6) 327-338
A kinematic wave model of overland flow was used to calculate hydraulic roughness coefficients for earth covers and native hillslope surfaces at a waste burial site. Manning's n roughness coefficients were greater on earth cover plots planted to crested wheatgrass (n = 0.076) than on those planted to streambank wheatgrass...
Suspension freezing of bottom sediment and biota in the Northwest Passage and implications for Arctic Ocean sedimentation
E. Reimnitz, L. Marincovich Jr., M. McCormick, W.M. Briggs
1992, Canadian Journal of Earth Sciences (29) 693-703
Ice observations and sediment collected in a summer transit through the Northwest Passage provide insights on suspension freezing, the most important sediment entrainment mechanism for the Arctic Ocean. No evidence was seen for entrainment by bottom adfreezing, bluff slumping, river flooding, dragging ice keels, or significant eolian transport from land...
Use of a regional atmospheric model to simulate lake-atmosphere feedbacks associated with Pleistocene Lakes Lahontan and Bonneville
S. W. Hostetler, F. Giorgi
1992, Climate Dynamics (7) 39-44
A regional model of the atmosphere (version 4 of the NCAR mesoscale model, MM4) was used to assess whether lake-effect precipitation was a significant component of the late-Pleistocene hydrologic budgets of Lakes Lahontan and Bonneville. Control simulations for January and July of 1979 were made using MM4, and the Pleistocene...
Computer simulation of dry layered granular flow down an incline composed of grains
Chi-Hai Ling, Chyan-Deng Jan
1992, Conference Paper, Proceedings of Engineering Mechanics
Experiments show that gravity-driven dry granular flows are essentially layered for smooth spheres. This paper describes layer-to-layer interaction in the flow. Assuming two-dimensional flow and neglecting the interaction of grains within the same layer, one may idealize the problem as an elastic sphere under external forces moving down an incline...
Comparison of purge and trap GC/MS and purgeable organic chloride analysis for monitoring volatile chlorinated hydrocarbons
Larry B. Barber, E. Michael Thurman, Yoshi Takahashi, Mary C. Noriega
1992, Ground Water (30) 836-842
A combined field and laboratory study was conducted to compare purge and trap gas chromatography/mass spectrometry (PT‐GC/MS) and purgeable organic chloride (POC1) analysis for measuring volatile chlorinated hydro‐carbons (VCH) in ground water. Distilled‐water spike and recovery experiments using 10 VCH indicate that at concentrations greater than...
Thermal waters along the Konocti Bay fault zone, Lake County, California: a re-evaluation
J. M. Thompson, Robert H. Mariner, L. D. White, T. S. Presser, William C. Evans
1992, Journal of Volcanology and Geothermal Research (53) 167-183
The Konocti Bay fault zone (KBFZ), initially regarded by some as a promising target for liquid-dominated geothermal systems, has been a disappointment. At least five exploratory wells were drilled in the vicinity of the KBFZ, but none were successful. Although the Na-K-Ca and Na-Li geothermometers indicate that the thermal waters...
General circulation model simulations of winter and summer sea-level pressures over North America
G. J. McCabe Jr., D.R. Legates
1992, International Journal of Climatology (12) 815-827
Temporal variability of synoptic-scale circulation is a dominant factor in regional temporal climate variations. In the midlatitudes, temporal variability of synoptic-scale circulation has been found to be related to temporal variations in regional air temperature and precipitation. General circulation model (GCM) simulations of long-term changes in synoptic-scale circulation may be...
Sediment bioaccumulation testing with fish
Michael J. Mac, Christopher J. Schmitt
G. Allen Burton Jr., editor(s)
1992, Book chapter, Sediment toxicity assessment
In this chapter, we discuss methods for conducting bioaccumulation bioassays with fish; the advantages and disadvantages of using fish rather than invertebrates; and problems associated with bioaccumulation testing, with a special emphasis on statistical treatment....
Intraspecific variation in egg shape among individual emperor geese
Margaret R. Petersen
1992, Journal of Field Ornithology (63) 344-354
Within-clutch variability in shape of 1743 eggs from 301 nests of Emperor Geese (Chen canagicus) laid over a 5-yr period was measured. Individual females laid similar shaped eggs in successive years, and eggs among clutches within females could not be distinguished. Cluster analysis correctly identified 69.9% of 136 known conspecific...
A new device for collection of interstitial water from wetland sediments
Ned H. Euliss Jr., Ronald K. Barnes
1992, Wetlands Ecology and Management (1) 233-237
A sampler for collection of interstitial water from wetland sediments is described. It differs from other sampling devices because it does not have to be filled with solution to facilitate diffusion, it does not have to be removed from the wetland to collect samples, and it can be used to...
Lake trout spawning habitat in the Six Fathom Bank-Yankee Reef lake trout sanctuary, Lake Huron
Thomas A. Edsall, Charles L. Brown, Gregory W. Kennedy, Thomas P. Poe
1992, Journal of Great Lakes Research (18) 70-90
Attempts to reestablish self-sustaining stocks of lake trout (Salvelinus namaycush) in the lower four Great Lakes, where the species was extinguished in the 1950s and 1960s, have been largely unsuccessful. To avoid many of the problems believed to be contributing to this failure, the fishery management community recently established several...
Implications for faunal habitat related to altered macrophyte structure in regulated lakes in northern Minnesota
Douglas A. Wilcox, James E. Meeker
1992, Wetlands (12) 192-203
Water-level regulation has altered the plant species composition and thus the structure of nearshore aquatic macrophyte communities in two regulated lakes in northern Minnesota as compared with a nearby unregulated lake. Results of previous faunal studies in the regulated lakes were used as a basis for assessing the effects of...
Accumulation of mercury by aufwuchs in Wisconsin seepage lakes: Implications for monitoring
W. Gregory Cope, Ronald G. Rada
1992, Archives of Environmental Contamination and Toxicology (23) 172-178
We examined temporal variation in the total Hg content of aufwuchs collected from artificial substrates in 11 seepage lakes in north-central Wisconsin and its relation to the Hg content of resident yellow perch Perca flavescens from the lakes. Dry weight concentrations of Hg in aufwuchs varied temporally, as follows: summer/fall 1985 > summer 1985 > spring/summer...
