R. C. Cipriano, W. B. Schill, S. W. Pyle, R. Horner
1986, Journal of Wildlife Diseases (22) 488-492
Enteric redmouth disease is described in chinook salmon (Oncorhynchus tshawytscha) at a state hatchery in Sand Ridge, Illinois. Biochemical, isoenzyme, and serological data indicated that the epizootic was caused by a sorbitol-fermenting Serovar 2 strain of Yersinia ruckeri. In laboratory experiments the isolate was...

C. A. Lemm, D. V. Rottiers
1986, Progressive Fish-Culturist (48) 101-106
Growth rates of tiger muskellunge (muskellunge Esox masquinongy ♀ x northern pike E. lucius ♂) fed diets containing 35, 45, or 55% crude protein for 5 weeks at 17, 20, or 23°C were compared. Fish fed diets containing 45 or 55% protein grew faster at all temperatures than those fed...
Modern alluvial history of the Paria Rver drainage basin, southern Utah
R. Hereford
1986, Quaternary Research (25) 293-311
Stream channels in the Paria River basin were eroded and partially refilled between 1883 and 1980. Basin-wide erosion began in 1883; channels were fully entrenched and widened by 1890. This erosion occurred during the well-documented period of arroyo cutting in the Southwest. Photographs of the Paria River channel taken between...
Increased walleye egg hatch and larval survival after protease treatment of eggs
W. F. Krise, L. Bulkowski-Cummings, A.D. Shellman, K. A. Kraus, R. W. Gould
1986, Progressive Fish-Culturist (48) 95-100
Various techniques for eliminating the clumping of newly spawned walleye eggs (Stizostedion vitreum) were evaluated by measuring hatch, growth, and survival. Percent hatch was highest (83%) in egg groups water hardened in 0.01% protease solution. Other water‐hardening techniques tested were: (1) continuous stirring; (2) 250 mg/L tannic acid solution; and...

Ronald J. Jameson, James L. Bodkin
1986, Marine Mammal Science (2) 305-309
On 3 October 1984 at 0928 h (PST) near Pt. San Simeon, California (35°39’N, 121°11’W), we observed a female sea otter (Enhydra lutris) resting in a kelp bed (Macrocystis pyrifera) with a small pup on her chest; approximately 2 m away another small pup floated unattended in the kelp. The...
The effects of sliding velocity on the frictional and physical properties of heated fault gouge
Diane E. Moore, R. Summers, J.D. Byerlee
1986, Pure and Applied Geophysics PAGEOPH (124) 31-52
The frictional properties of a crushed granite gouge and of gouges rich in montmorillonite, illite, and serpentine minerals have been investigated at temperatures as high as 600??C, confining pressures as high as 2.5 kbar, a pore pressure of 30 bar, and sliding velocities of 4.8 and 4.8??10-2 ??m/sec. The gouges...

CHARACTERIZATION OF SANDSTONE RESERVOIRS FOR ENHANCED OIL RECOVERY: THE PERMIAN UPPER MINNELUSA FORMATION, POWDER RIVER BASIN, WYOMING.
Christopher J. Schenk, J. W. Schmoker, J.M. Scheffler
1986, Conference Paper, Society of Petroleum Engineers of AIME, (Paper) SPE
Upper Minnelusa sandstones form a complex group of reservoirs because of variations in regional setting, sedimentology, and diagenetic alteration. Structural lineaments separate the reservoirs into northern and southern zones. Production in the north is from a single pay sand, and in the south from multi-pay sands due to differential erosion...
Influence of weather and density on lamb survival of desert mountain sheep
Charles L. Douglas, David M. Leslie Jr.
1986, Journal of Wildlife Management (50) 153-156
This report concerns the effect of weather on lamb survival in desert mountain sheep (Ovis canadensis nelsoni) to 6-8 months of age in the River Mountains, Nevada, and how it integrates with density to limit the population. Regression analyses were used to examine relationships between lamb survival and weather variables...
Quantitative and qualitative studies of gut flora in striped bass from estuarine and coastal marine environments
R.D. MacFarlane, J.J. McLaughlin, G. L. Bullock
1986, Journal of Wildlife Diseases (22) 344-348
Examination of the intestinal contents of 130 striped bass (Morone saxatilis) collected from the Hudson River and Long Island Sound during May to October 1981 showed that opportunistic fish pathogens—especially Aeromonas hydrophila—predominated in samples from both locations. Other isolates from both groups of striped...
Stick slip, charge separation and decay
D.A. Lockner, J.D. Byerlee, V.S. Kuksenko, A.V. Ponomarev
1986, Pure and Applied Geophysics PAGEOPH (124) 601-608
Measurements of charge separation in rock during stable and unstable deformation give unexpectedly large decay times of 50 sec. Time-domain induced polarization experiments on wet and dry rocks give similar decay times and suggest that the same decay mechanisms operate in the induced polarization response as in the relaxation of...
Research in earthquake prediction - the Parkfield prediction experiment
Henry Spall
1986, Earthquakes & Volcanoes (USGS) (18) 148-148
The 15-mile-long Parkfield, California, section of the Sam Andreas fault is the best understood earthquake source region in the world. Moderate-sized earthquakes of local magnitude 5 3/4 occurred at Parkfield in 1881, 1901, 1922, 1934, and 1966....
Parkfield Earthquake looks to be on schedule
1986, Earthquakes & Volcanoes (USGS) (18) 149-150
The only formally endorsed prediction of an earthquake in the Unites States appears to be holding up well. The magnitude 5.6 Parkfield Earthquake, expected to strike a section of the San Andreas in sparsely populated central California in January 1988, give or take 5 years, would appear to be on...
Precambrian basement geology of North and South Dakota
J. S. Klasner, E. R. King
1986, Canadian Journal of Earth Sciences (23) 1083-1102
Combined analysis of drill-hole, gravity, and magnetic data indicates that the buried Precambrian basement rocks of the Dakotas can be divided into several lithotectonic terranes. Eastern North Dakota and northeastern South Dakota are underlain by Archean gneiss. Except for the Black Hills region of South Dakota, where Archean rocks are...
Evidence for a stronger oxygen-minimum zone off central California during late Pleistocene to early Holocene
J.V. Gardner, E. Hemphill-Haley
1986, Geology (14) 691-694
Of 31 deep-sea cores collected along the central California continental slope, 18 have distinctly laminated sediment at depth, but none have laminations in the top few centimetres. The cores with laminated facies are restricted to water depths between 508 and 1508 m, but...
FUNDAMENTAL MODAL BEHAVIOR OF AN EARTHQUAKE-EXCITED BRIDGE.
A. G. Brady, M. Çelebi
1986, Conference Paper
The magnitude 6. 1 Morgan Hill, California, earthquake of April 24, 1984, produced a set of acceleration records at the freeway overpass in San Jose carrying I-280/I-680 across U. S. 101, 12 km from the epicenter. Peak accelerations reached 0. 10 g at ground level and 0. 16 g in...

Garnet megacrysts of the Williams diatremes, north-central Montana.
E. S. McGee
1986, American Mineralogist (71) 674-681
The physical characteristics of garnet megacrysts from the Williams diatremes are described, analysed and compared with other garnet megacryst suites. The only correlation found between the physical characteristics and the composition of the megacrysts related deep-red colour to high Cr content.-J.A.Z....
Design and cost analysis of rapid aquifer restoration systems using flow simulation and quadratic programming
L.J. Lefkoff, S.M. Gorelick
1986, Groundwater (24) 777-790
Detailed two-dimensional flow simulation of a complex ground-water system is combined with quadratic and linear programming to evaluate design alternatives for rapid aquifer restoration. The design model ensures that a contaminant plume is removed and treated within four years at the least possible cost. Rapid restoration is accomplished by maintaining...

Invertebrate communities associated with Bangia atropurpurea and Cladophora glomerata in western Lake Erie
E.W. Chilton, R.L. Lowe, K.M. Schurr
1986, Journal of Great Lakes Research (12) 149-153
The appearance of the marine alga Bangia atropurpurea (Rhodophyta) in Lake Erie has been followed by its rapid dispersal throughout the eulittoral zone of the lake. Bangia was extensively sampled to determine its suitability as a habitat for littoral organisms. Present data indicate that the only organisms capable of maintaining...
Computer program calculation of gas supersaturation in water
V. K. Dawson
1986, Progressive Fish-Culturist (48) 142-146
A short computer program, written in BASIC for the Apple IIe or IBM PC computer, efficiently performs all the calculations required to determine gas pressure and percent saturation values for water. Input for the program is limited to empirical determinations of barometric pressure, water temperature, differential dissolved gas pressures, dissolved...
