A "virus" disease of chinook salmon
A. J. Ross, R.R. Rucker
1960, Fishery Leaflet 497
Epizootics among chinook salmon fingerlings at the Coleman National Fish Hatchery have occurred periodically since 1941. A virus or virus-like filterable agent has been demonstrated to be the causative agent of this disease....

Automatic measurements and computations for radiochemical analyses
J. N. Rosholt, J. R. Dooley Jr.
1960, Analytical Chemistry (32) 1093-1098
In natural radioactive sources the most important radioactive daughter products useful for geochemical studies are protactinium-231, the alpha-emitting thorium isotopes, and the radium isotopes. To resolve the abundances of these thorium and radium isotopes by their characteristic decay and growth patterns, a large number of repeated alpha activity measurements on...
Diagenesis of metabolites and a discussion of the origin of petroleum hydrocarbons
Irving A. Breger
1960, Geochimica et Cosmochimica Acta (19) 297-308
Proteins and carbohydrates are rapidly degraded to compounds of no direct interest in the problem of the origin of petroleum. Lignin, if carried into marine basins in the form of humic substances, is probably the major progenitor of kerogen rather than the precursor of petroleum. Pigments are but minor contributors...
Potentiometric titration and equivalent weight of humic acid
A. M. Pommer, Irving A. Breger
1960, Geochimica et Cosmochimica Acta (20) 30-44
The “acid nature” of humic acid has been controversial for many years. Some investigators claim that humic acid is a true weak acid, while others feel that its behaviour during potentiometric titration can be accounted for by colloidal adsorption of hydrogen ions. The acid character of humic acid has been...
The crystal structure of cesium biuranyl trisulphate, Cs2(UO2)2(SO4)3
M. Ross, H. T. Evans Jr.
1960, Journal of Inorganic and Nuclear Chemistry (15) 338-351
The crystal structure of the new compound Cs(UO2)2(SO4)3 has been determined by X-ray diffraction methods. The compound is tetragonal, space group P421m">P421m (D2d3), with a = 9·62 ± 0·02, c = 8·13 ± 0·01Å">c = 8·13 ± 0·01Å, and Z = 2; s.g. (calc.)...
Determination of niobium in the parts per million range in rocks
F. S. Grimaldi
1960, Analytical Chemistry (32) 119-121
A modified niobium thiocyanate spectrophotometric procedure relatively insensitive to titanium interference is presented. Elements such as tungsten, molybdenum, vanadium, and rhenium, which seriously interfere in the spectrophotometric determination of niobium, are separated by simple sodium hydroxide fusion and leach; iron and magnesium are used as carriers for the niobium. Tolerance...
Effect of crystal thickness and geometry on the alpha-particle resolution of CsI (Tl)
P. Martinez, F. E. Senftle
1960, Review of Scientific Instruments (31) 974-977
The resolution of CsI(Tl) for Po210 alpha particles has been measured as a function of crystal thickness. The best resolution of a ½‐in. diam cylindrical crystal was obtained for a thickness of 0.38 mm, and the effect of thickness on the resolution is discussed. Based on the proposed model, a conical crystal...

First-year growth of the walleye, Stizostedion vitreum vitreum (Mitchill), and associated factors in the Red Lakes, Minnesota
Lloyd L. Smith Jr., Richard L. Pycha
1960, Limnology and Oceanography (5) 281-290
First-year growth of the walleye, Stizostedion vitreum vitreum (Mitchill), was studied from 4,544 fish collected during the first summer of life in the Red Lakes in six seasons and from back calculations on 4,474 fish one year or more in age representing 17 year classes. Sexes did not differ in growth rate....
Age and growth of the whitefish Coregonus clupeaformis, of Munising Bay, Lake Superior
Thomas A. Edsall
1960, Transactions of the American Fisheries Society (89) 323-332
This study is based on a sample of 415 whitefish collected in 1953 from an unexploited population in Munising Bay, Lake Superior. Gill-net and trawl catches had different length-frequency distributions and age compositions, but estimates of growth from the two catches were very similar. The body-scale relation is...
Magnetic susceptibility of tetragonal titanium dioxide
F. E. Senftle, T. Pankey, F. A. Grant
1960, Physical Review (120) 820-825
Careful measurements have been made of the magnetic susceptibility of the rutile and anatase crystalline forms of titanium dioxide. The magnetic susceptibility of a single crystal of high-purity rutile was found to be (0.067±0.0015)×<span id="MJXc-Node-6"...
Releasing effects in flame photometry. Determination of calcium
J. I. Dinnin
1960, Analytical Chemistry (32) 1475-1480
Strontium, lanthanum, neodymium, samarium, and yttrium completely release the flame emission of calcium from the depressive effects of sulfate, phosphate, and aluminate. Magnesium, beryllium, barium, and scandium release most of the calcium emission. These cations, when present in high concentration, preferentially form compounds with the depressing anions when the solution...

The bottom fauna of Lake Huron
Howard D. Teter
1960, Transactions of the American Fisheries Society (89) 193-197
The examination of 63 bottom samples, collected in Lake Huron in 1952 and 1956, revealed that Pontoporeia affinis was the dominant organism in both deep and shallow water. The next most abundant organisms in deep water were oligochaetes, fingernail clams, and midge larvae. Midge larvae were more numerous than either...
