Pathophysiology of infectious hematopoietic necrosis virus disease in rainbow trout: Hematological and blood chemical changes in moribund fish
D.F. Amend, L. Smith
1975, Infection and Immunity (11) 171-179
Infectious hematopoietic necrosis (IHN) is a rhabdoviral disease of rainbow trout (Salmo gairdneri). Trout were injected with IHNV, and various hematological and biochemical measurements of clinically ill fish were compared to uninfected controls. Infected fish had reduced corpuscular counts, hemoglobin, and packed cell volume, but normal mean corpuscular volume, mean...
Determining earthquake recurrence intervals from deformational structures in young lacustrine sediments
John D. Sims
1975, Tectonophysics (29) 141-152
Examination of the silty sediments in the lower Van Normal reservoir after the 1971 San Fernando, California earthquake revealed three zones of deformational structures in the 1-m-thick sequence of sediments exposed over about 2 km2 of the reservoir bottom. These zones are correlated with moderate earthquakes that shook the San Fernando...
The determination of specific forms of aluminum in natural water
R.B. Barnes
1975, Chemical Geology (15) 177-191
A procedure for analysis and pretreatment of natural-water samples to determine very low concentrations of Al is described which distinguishes the rapidly reacting equilibrium species from the metastable or slowly reacting macro ions and colloidal suspended material. Aluminum is complexed with 8-hydroxyquinoline (oxine), pH is adjusted to 8.3 to...

Thin-section electron microscopy of mature Myxosoma cerebralis (Myxosporidea) spores
P.D. Lunger, B.L. Rhoads, K. Wolf, M.E. Markiw
1975, Journal of Parasitology (61) 476-480
The morphology of purified, mature Myxosoma cerebralis spores was examined by thin-section electron microscopy. Surface architecture corresponded closely to that described in an earlier scanning electron microscopy study of this organism (Lom and Hoffman, 1971). A uniformly thick spore wall is composed of finely granular, electron-lucent material. Intrawall "valvoplasm" at...
Thermomagnetic analysis of meteorites, 2. C2 chondrites
D.E. Watson, E.E. Larson, J.M. Herndon, M.W. Rowe
1975, Earth and Planetary Science Letters (27) 101-107
Samples of all eighteen of the known C2 chondrites have been analyzed thermomagnetically. For eleven of these, initial Fe3O4 content is low (generally <1%) and theJs-T curves are irreversible. The heating curves show variable greater (up to 10 times) than it is initially. This...

Geothermal significance of eastward increase in age of upper Cenozoic rhyolitic domes in southeastern Oregon
Norman S. MacLeod, George Walton Walker, Edwin H. McKee
1975, Open-File Report 75-348
Rhyolitic domes, flows, and ash-flow tuffs of Miocene to Holocene age form an important part of the thick sequence of Cenozoic volcanic rocks that cover southeastern Oregon east of the Cascade Range. Rhyolitic domes 11-17 m.y. old are widespread, particularly in the easternmost part of the state and in adjacent...
Gut morphology of mallards in relation to diet quality
M. R. Miller
1975, Journal of Wildlife Management (39) 168-173
Digestive organ lengths, weights, and volumes in each of three groups of mallards (Anas platyrhynchos) were determined at the end of a 21-day period, during which one group was starter (control diet), another group was fed whole corn (low fiber content), and the third fed alfalfa pellets (high fiber content)...
The Sargent-Berrocal Fault Zone and its relation to the San Andreas Fault system in the southern San Francisco Bay region and Santa Clara Valley, California
Robert McLaughlin
1974, Journal of Research of the U.S. Geological Survey (2) 593-598
The Sargent-Berrocal fault zone is a belt of thrust faults extending for about 58 mi (94 km) southeastward from the vicinity of Los Altos to San Juan Bautista, Calif. The fault zone generally dips southwestward toward the adjacent San Andreas fault at low to steep angles, and the southwest...
The association of geochemical anomalies with a negative gravity anomaly in the Chief Mountain-Soda Creek area, Clear Creek County, Colorado
G.C. Curtin, H. D. King
1974, Journal of Research of the U.S. Geological Survey (2) 581-592
Geochemical studies in the Chief Mountain Soda Creek area, Clear Creek County, Colo., show that anomalously high amounts of Au, Ag, Pb, Zn, Cd, and Bi in mull ash, and Cu and Hg in soil, correspond to a negative gravity anomaly in the Front Range mineral belt. The correspondence of...
Stratigraphic relations of the Bolsa Quartzite, Vekol Mountains, Pinal County, Arizona
M.A. Chaffee
1974, Journal of Research of the U.S. Geological Survey (2) 143-146
A quartzite unit occurring between the rocks of the Precambrian Apache Group and those of the Cambrian Abrigo Formation in the Vekol Mountains, Final County, Ariz., has been called both Troy Quartzite (Precambrian) and Bolsa(?) Quartzite (Cambrian). Regional and local geologic relationships indicate that this intervening unit is definitely the...

Polychlorinated biphenyl toxicity to Japanese quail as related to degree of chlorination
E. F. Hill, R.G. Heath, J. W. Spann, J.D. Williams
1974, Poultry Science (53) 597-604
To learn if the percentage of chlorine in a mixture of polychlorinated biphenyls (PCB’s) alone determines toxicity, Japanese quail were fed diets containing Aroclor 1248, 1254, or 1260 at levels that added equal amounts of chlorine to the feed. The experiment comprised two consecutive 5-day periods; three sublethal concentrations of...
