Investigation of detection limits for solutes in water measured by laser raman spectrometry
Kirkwood M. Cunningham, Marvin C. Goldberg, Eugene R. Weiner
1977, Analytical Chemistry (49) 70-75
The influence of experimental parameters on detection sensitivity was determined for laser Raman analysis of dissolved solutes in water. Individual solutions of nitrate, sulfate, carbonate, bicarbonate, monohydrogen phosphate, dihydrogen phosphate, acetate ion, and acetic acid were measured. An equation is derived which expresses the signal-to-noise ratio in terms of solute...
Earthquakes in the United States
C. Stover
1977, Earthquake Information Bulletin (USGS) (9) 32-33
To supplement data in the report Preliminary Determination of Epicenters (PDE), the National earthquake Information Service (NEIS) also publishes a quarterly circular, Earthquakes in the United States. This provides information on the felt area of U.S earthquakes and their intensity. The main purpose is to describe the larger effects of these earthquakes so that...
Earthquake history of Tennessee
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 37-39
The western part of the State was shaken strongly by the New Madrid, Mo., earthquakes of 1811-12 and by earthquakes in 1843 and 1895. The area has also experienced minor shocks. Additional activity has occurred in the eastern part of the State, near the North Carolina border. Forty shocks of...
Earthquake history of Virginia
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 28-30
Virginia is a State of considerable seismic activity, although the earthquakes are rarely strong. Thirty-five shocks, intensity MM V or greater (Modified Mercalli Scale), are listed with epicenters within its borders. The locations of several of the older events are not precise; thus, the above count i subject to alteration....

Mitigating earthquakes; the federal role
F. Press
1977, Earthquake Information Bulletin (USGS) (9) 4-5
With rapid approach of a capability to make reliable earthquake forecasts, it essential that the Federal Government play a strong, positive role in formulating and implementing plans to reduce earthquake hazards. Many steps are being taken in this direction, with the President looking to the Office of Science and Technology...
Immunization of pacific salmon: comparison of intraperitoneal injection and hyperosmotic infiltration of Vibrio anguillarum and Aeromonas salmonicida bacterins
Ross Antipa, Donald F. Amend
1977, Journal of the Fisheries Research Board of Canada (34) 203-208
Two methods of immunizing fish, intraperitoneal (i.p.) injection and hyperosmotic infiltration, were compared for control of vibriosis and furunculosis in pen-reared coho salmon (Oncorhynchus kisutch) and chinook salmon (O. tshawytscha). Both methods provided significant protection against vibriosis under field test conditions. In coho salmon, hyperosmotic infiltration provided the best protection and...
Evaluating the intensity of U.S. earthquakes
R. Simon, C. Stover
1977, Earthquake Information Bulletin (USGS) (9) 24-29
The intensity scale based on the Modified Mercalli Scale of 1931 (MM scale) measures the effects of seismic shaking. Intensity estimations are often the only representation of the size of an earthquake when small shocks occur in areas far removed from seismograph stations that can record them instrumentally. The impossibility...
The display flight of The North American Ruddy Duck
M. R. Miller, R.M. McLandress, B.J. Gray
1977, The Auk (94) 140-142
Sexual behavior of the North American Ruddy Duck (Oxyura jamaicensis), as summarized by Johnsgard (1965: 323-327), includes a display variously referred to as the ringing rush (Johnsgard 1965: 325; 1967), ring rush (Johnsgard 1966), and/or display flight (Johnsgard 1966, 1967), which males perform as a short rush across the water...
Energy allocation patterns of a sprouting and nonsprouting species of Arctostaphylos in the California chaparral
Jon E. Keeley, Sterling C. Keeley
1977, American Midland Naturalist (98) 1-10
The r- and K-selection theory was used to generate testable hypotheses about patterns of energy allocation in two chaparral shrubs of different reproductive strategies. Terminal-branchlet vegetative and reproductive biomass of the nonsprouting Arctostaphylos glauca and the sprouting A. glandulosa were sampled in a 23-year-old and a 90-year-old stand of chaparral...

Interpretation of discordant 40Ar/39Ar age-spectra of mesozoic tholeiites from Antarctica
R.J. Fleck, J. F. Sutter, D.H. Elliot
1977, Geochimica et Cosmochimica Acta (41) 15-32
Conventional K-Ar ages of tholeiitic basalts of the Ferrar Group in the central Transantarctic Mountains indicate significant loss of radiogenic 40Ar from this unit over much of its outcrop area. Argon loss varies inversely with amount of devitrified matrix in the basalts, which have not been thermally or tectonically disturbed since...

The stereoisomeric composition of phytanyl chains in lipids of Dead Sea sediments
R. Anderson, M. Kates, M.J. Baedecker, I.R. Kaplan, R.G. Ackman
1977, Geochimica et Cosmochimica Acta (41) 1381-1390
Lipid extracts from five recent Dead Sea sediments were analyzed for isoprenoid compounds and the following were isolated: free and phospholipid-bound di-O-phytanylglycerol, free phytanol and free and esterifled phytanic acid. The phytanyl groups of the diether and the free phytanol were oxidized to the corresponding phytanic acid; the stereoisomeric composition...

A note on the effect of fault gouge composition on the stability of frictional sliding
R. Summers, J. Byerlee
1977, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (14) 155-160
The frictional properties of fault gouge have been studied at confining pressures to 6 kbars. If the gouge is composed of strong materials such as crushed granite or quartz sand, the frictional strength is high, and violent stick-slip occurs at confining pressures above approximately 1.5 kbars. If the gouge is...
