Vacuum-jacketed hydrofluoric acid solution calorimeter
R. A. Robie
1965, Review of Scientific Instruments (36) 484-486
A vacuum‐jacketed metal calorimeter for determining heats of solution in aqueous HF was constructed. The reaction vessel was made of copper and was heavily gold plated. The calorimeter has a cooling constant of 0.6 cal‐deg−1‐min−1, approximately ¼ that of the air‐jacketed calorimeters most commonly used with HF. It reaches equilibrium within 10 min after turning off the heater current. Measurements...
Servo-amplifiers for ion current measurement in mass spectrometry
J. S. Stacey, R.D. Russell, F. Kollar
1965, Journal of Scientific Instruments (42) 390-394
A servo-voltmeter can provide a useful alternative to the d.c. amplifier or vibrating reed electrometer for the accurate measurement of mass spectrometer ion currents, and has some advantages which recommend its use in certain applications. A generalized analysis based on servomechanism theory is presented as an aid for understanding the...
Eocene and miocene rocks off the northeastern coast of the United States
T. G. Gibson
1965, Deep-Sea Research and Oceanographic Abstracts (12)
A grab sample from a depth of 1675 m at a point south of Cape Cod contains early Eocene planktonic Foraminifera and is correlated with the Globorotalia rex zone of Trinidad. The assemblage indicates a depth comparable to that existing today. Regional relations suggest that the Cretaceous and Eocene deposits deepen...
The binary system K2SO4CaSO4
J.J. Rowe, G.W. Morey, I.D. Hansen
1965, Journal of Inorganic and Nuclear Chemistry (27) 53-58
The binary system K2SO4CaSO4 was studied by means of heating-cooling curves, differential thermal analysis, high-temperature quenching technique and by means of a heating stage mounted on an X-ray diffractometer. Compositions and quench products were identified optically and by X-ray. Limited solid solution of CaSO4 in...
Geochemistry of Birch Creek, Inyo County, California a travertine depositing creek in an arid climate
I. Barnes
1965, Geochimica et Cosmochimica Acta (29) 85-112
A small stream in eastern California was studied in detail to determine the causes of travertine deposition from the stream. Although the ground water feeding the stream is slightly supersaturated to just saturated with calcite, the ground water is supersaturated with CO2 with respect...
Titanium dioxide in pyroclastic layers from volcanoes in the cascade range
G.K. Czamanske, S.C. Porter
1965, Science (150) 1022-1025
Rapid determinations of titanium dioxide have been made by x-ray emission techniques to evaluate the potentiality of using the TiO2 content of samples for checking field correlations and assisting in identification of pyroclastic units from Cascade volcanoes. Preliminary data suggest that the two most wide-spread units have characteristic ranges of...
Natural recharge and localization of fresh ground water in Kuwait
R.E. Bergstrom, R.E. Aten
1965, Journal of Hydrology (2) 213-231
Fresh ground water (200 parts per million total dissolved solids and upwards) occurs in portions of Pleistocene sandstone aquifers beneath basins and wadis in north Kuwait where the mean rainfall is about five inches per year. The fresh water is surrounded and underlain by brackish water (> 4000 ppm TDS)....
Relative toxicities of similar formulations of pyrethrum and rotenone to fish and immature stoneflies
W.R. Bridges, O.B. Cope
1965, Pyrethrum Post (8) 3-5
The insecticidal properties of rotenone and pyrethrum have been known for many years. Both toxicants have long histories of extensive use for control of a variety of insect pests. Rotenone has been also employed as a management tool by fishery biologists to rehabilitate fishing waters, and its toxicity to fish...
Field application methods for recovery of the selective lampricide, 3-trifluoromethyl-4-nitrophenol
Thomas J. Billy, Stacy L. Daniels, Lloyd L. Kempe, Alfred M. Beeton
1965, Conference Paper, Proceedings of the 8th Conference on Great Lakes Research
Colorimetric methods are described for the detection of residues of the selective lampricide, 3-trifluoromethyl-4-nitrophenol (TFM), in natural waters and fish tissues. Solvent extraction and anion exchange were used to separate and concentrate the lampricide, and to reduce high background colors which often interfere with the determinations. Data from the Pentwater...
Quality of surface water in the Sevier Lake basin, Utah
D. C. Hahl, R.E. Cabell
1965, Utah Basic-Data Release 10
Few data are available on the quality of surface waters in the Sevier Lake basin. Because of the need for information not only on the chemical-quality but also on the other water-quality characteristics of the basin, the U.S. Geological Survey, as part of its cooperative program with the Utah State...
Hydrology of the Little Plover River basin, Portage County, Wisconsin, and the effects of water resource development
Edwin P. Weeks, Donald W. Erickson, Charles Lee Roy Holt Jr.
1965, Water Supply Paper 1811
The Little Plover River basin is in the sand-plain area of central Wisconsin. The basin and the surrounding sand-plain area provide a good fish and wildlife habitat and is a popular locale for sport fishing. Good yields may be obtained in the area from irrigated crops, and the irrigated acreage...

Ground-water pumpage and water-level changes in the Milwaukee-Waukesha area, Wisconsin, 1950-61
J. H. Green, R. D. Hutchinson
1965, Water Supply Paper 1809-I
Artesian water pressure in the deep sandstone aquifer continued to decline throughout most of the Milwaukee-Waukesha area, Wisconsin between 1950 and 1961. Areas of greatest water-level decline were in northeast Waukesha County and in northwest Milwaukee County. The chief cause of the decline was continued heavy pumpage. The major aquifers...
