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...
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...
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...

A compilation of chemical quality data for ground and surface waters in Utah
John G. Connor, C.G. Mitchell
1958, Technical Publication 10
An accelerated use of water resulting from a growing population, industrial expansion, and irrigation has brought into focus the importance of the quality as well as the quantity of this natural resource in Utah. As new demands are made on the existing supply, a search goes on for new sources...

A possible cause of sunburn in fish
1958, Progressive Fish-Culturist (20) 111-113
A LESION DESCRIBED AS A GRAY ΡATCH GENERALLY LOCATED ΑΝΤΕRIOR TO THE DORSAL FIN has been associated with high mortality of fish on numerous occasions in production hatcheries throughout the United States. This lesion has been called "sunburn" or "backpeel." No bacteria or other pathogens have been found in fish...

Rapid counting of nematoda in salmon by peptic digestion
Joseph A. Stern, Diptiman Chakravarti, Joseph R. Uzmann, M. N. Hesselholt
1958, Special Scientific Report - Fisheries 255
The nematode parasite Anisakis sp. can be recovered, relatively unaltered, from chum salmon musculature by high temperature (52°+2°C.) peptic digestion of the flesh. The procedure, which is presented in detail, appears to be more thorough in isolating the parasite than dissection of the flesh and manual isolation of the worms. In...

The Mourning Dove is a widespread species breeding in the non-boreal regions of North and Middle America and from the West Indies south to Panama. It is hunted extensively in many sections of the United States and in some sections of Canada, the West Indies, and Mexico....The trends in geographic...
Birds and Dutch elm disease control

Brief, factual review of information on effect of DDT and other insecticides on birds. One program for control of elm disease caused 22% decrease in number of adult birds and 56% mortality of nestlings. Quail fed 3 oz. of DDT per ton of food had 16% reduction in young...
A procedure for removing the effect of response bias errors from waterfowl hunter questionnaire responses
E. L. Atwood
1958, Biometrics (14) 132-146
Response bias errors are studied by comparing questionnaire responses from waterfowl hunters using four large public hunting areas with actual hunting data from these areas during two hunting seasons. To the extent that the data permit, the sources of the error in the responses were studied and the contribution...
