Waterfowl sickness diagnoses in Minnesota, North Dakota, and Manitoba
Eugene F. Bossenmaier
1959, Journal of Wildlife Management (23) 113-115
This paper reports the results of an attempt to determine whether botulinus toxin or some other factor was responsible for avian sickness on water bodies in Minnesota, North and South Dakota, and at Whitewater Lake, Boissevain, Manitoba, in the summer of 1953....

Determination of chlorine in silicate rocks
L. C. Peck, E. J. Tomasi
1959, Analytical Chemistry (31) 2024-2026
In a rapid accurate method for the determination of chlorine in silicate rocks, the rock powder is sintered with a sodium carbonate flux containing zinc oxide and magnesium carbonate. The sinter cake is leached with water, the resulting solution is filtered, and the filtrate is acidified with nitric acid. Chlorine...
Geology and quicksilver deposits of the Terlingua district, Texas
Robert G. Yates, George A. Thompson
1959, Professional Paper 312
The Terlingua quicksilver district, which has produced more than 150,000 flasks of quicksilver, is in the southern part of the Big Bend region of southwestern Texas. It is a narrow, eastwest area about 20 miles long and lies mainly in southwestern Brewster County. The district is connected by graded road...
Burrowing activities of the larval lamprey
Philip J. Sawyer
1959, Copeia (1959) 256-257
Since the appearance in 1950 of Applegate's work on the sea lamprey in Michigan (U. S. Fish and Wildl. Serv., Spec. Sci. Rept.; Fish, No. 55) and the subsequent development of means to...
New occurrences of ferroselite (FeSe2)
R. G. Coleman
1959, Geochimica et Cosmochimica Acta (16) 296-301
Iron selenide from the uranium-vanadium ores of the Colorado Plateau was under investigation when ferroselite was described as a new mineral in Russia by Bur'yanova and Komkov (1955). Association of ferroselite with selenian pyrite and marcasite within discrete areas of these uranium-vanadium deposits suggests an unusual environment of formation. Its association...
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...
Semimicrodetermination of combined tantalum and niobium with selenous acid
F. S. Grimaldi, M. Schnepfe
1959, Analytical Chemistry (31) 1270-1272
Tantalum and niobium are separated and determined gravimetrically by precipitation with selenous acid from highly acidic solutions in the absence of complexing agents. Hydrogen peroxide is used in the preparation of the solution and later catalytically destroyed during digestion of the precipitate. From 0.2 to 30 mg., separately or in...
α-Radioactivity of cerium-142
F. E. Senftle, T. W. Stern, V. P. Alekna
1959, Nature (184) 630
JOHNSON AND NIER1 have measured the atomic masses of some of the rare-earth isotopes and have shown that the mass difference cerium-142—(barium-138 + helium-4) is equivalent to 1.68 ± 0.10 MeV. Similar results for the naturally occurring samarium and neodymium isotopes show that the α-active isotope of each element is the one...
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...
The reclamation of Indian and Abrams creeks in Great Smoky Mountains National Park
Robert E. Lennon, Phillip S. Parker
1959, Special Scientific Report - Fisheries 306
A complete program of stream reclamation was developed and applied on Indian and Abrams creeks in Great Smoky Mountains National Park. A salt-resistivity technique was used to estimate the dilution and velocity of a toxicant in running water. Streamside toxicity trials on resident fishes established minimal, effective concentrations of the...
