Magnetic susceptibility of tektites and some other glasses
F. E. Senftle, A. Thorpe
1959, Geochimica et Cosmochimica Acta (17) 234-237
The magnetic susceptibility at several magnetic field strengths of about thirty tektites from various localities have been measured. The susceptibility ranges from 2 × 10−6 to about 7.9 × 10−6 e.m.u./g. Tektites from a given locality have similar susceptibilities. The intensity of magnetization of all the tektites measured is zero or very...
Aromatic fluorine compounds. VIII. Plant growth regulators and intermediates
G. C. Finger, M.J. Gortatowski, R.H. Shiley, R.H. White
1959, Journal of the American Chemical Society (81) 94-101
The preparation and properties of 41 fluorophenoxyacetic acids, 4 fluorophenoxypropionic acids, 2 fluorobenzoic acids, several indole derivatives, and a number of miscellaneous compounds are described. Data are given for many intermediates such as new fluorinated phenols, anisoles, anilines and nitrobenzenes. Most of the subject compounds are related to a number...
Composition of monazites from pegmatites in eastern Minas Gerais, Brazil
K. J. Murata, C. V. Dutra, da Costa, J.J.R. Branco
1959, Geochimica et Cosmochimica Acta (16) 1-14
Two zoned pegmatites in south-eastern Minas Gerais were sampled in detail for their content of monazite and xenotime and the monazite was analysed for certain of the rare-earth elements and thorium.The ratio of xenotime to monazite increases in both pegmatites from the wall toward the quartz core. The content of...

Effects of certain chemicals on mucus-producing cells of Petromyzon marinus
Philip J. Sawyer
1959, Transactions of the American Fisheries Society (88) 305-309
Tissue samples that contained slime-secreting cells were taken from the gills and epidermis of larval lampreys that had been poisoned by several compounds. Histochemical treatment of these pathological tissues helped delineate the fate of these mucus-producing areas of the ammocetes. It was shown that the slime-secreting cells, located at the...
The electrical resistivity meter in fishery investigations
Robert E. Lennon
1959, Special Scientific Report - Fisheries 287
A portable resistivity (or conductivity) meter is easily used in fishery investigations to obtain rapid and precise measurements of the electrical resistance (or conductance) of waters. These measurements can be used to estimate the total dissolved solids content of waters, to facilitate the selection of appropriate gear for efficient electrofishing,...
Core logs from Bristol, Cadiz, and Danby Dry Lakes, San Bernardino County, California
Allan Mordorf Bassett, D.H. Kupfer, F.C. Barstow
1959, Bulletin 1045-D
Detailed core logs of four holes drilled in Bristol, Cadiz, and Danby Dry Lakes in southeastern San Bernardirio County, Calif., are given in the present report. These 3 dry lakes lie in a chain of basins having a drainage area of 4,000 square miles which is made up of alluvial...
Ground-water resources of Riverton irrigation project area, Wyoming, with a section on chemical quality of ground water
Donald Arthur Morris, O. M. Hackett, K.E. Vanlier, E. A. Moulder, W. H. Durum
1959, Water Supply Paper 1375
The Riverton irrigation project area is in the northwestern part of the Wind River basin in west-central Wyoming. Because the annual precipitation is only about 9 inches, agriculture, which is the principal occupation in the area, is dependent upon irrigation. Irrigation by surface-water diversion was begum is 1906; water is...
Life history of the sea lamprey of Cayugaf Lake, New York
Roland L. Wigley
1959, Fishery Bulletin of the U.S. Fish and Wildlife Service 561-617
A life history study of the sea lamprey, Petromyson marinus Linnaeus, in Cayuga Lake, N.Y., was conducted during 1950, 1951, and 1952. One of the major objectives was to obtain biological data concerning this endemic stock of sea lampreys for comparison with the newly established stocks in the Great Lakes....
Some preliminary notes on the ground water in the Columbia River basalt
R. C. Newcomb
1959, Northwest Science (33) 1-18
The Columbia River basalt carries groundwater by percolation, largely along tabular interflow zones of variable permeability and continuity. At various places the water occurs under perched, unconfined, and confined conditions; at some places it occurs under all three conditions at different depths. Both initial and tectonic structural features, such as...
Free-radical concentrations and other properties of pile-irradiated coals
R.A. Friedel, Irving A. Breger
1959, Science (130) 1762-1762
Five coals reacted quite differently when they were exposed to pile-irradiation. Little or no change was found in free-radical content for the three coals of lowest carbon content, whereas the two coals of highest carbon content were found to have a considerable increase in free-radical content. The infrared spectra and...
