Spectrophotometric determination of uric acid and some redeterminations of its solubility
D. R. Norton, M. A. Plunkett, F. A. Richards
1954, Analytical Chemistry (26) 454-457
The present study was initiated in order to develop a rapid and accurate method for the determination of uric acid in fresh, brackish, and sea water. It was found that the spectrophotometric determination of uric acid based upon its reaction with arsenophosphotungstic acid reagent in the presence of cyanide ion...
Fluctuations in production and abundance of commercial species in the Red Lakes, Minnesota, with special reference to changes in the walleye population
Lloyd L. Smith Jr., Laurits W. Krefting
1954, Transactions of the American Fisheries Society (83) 131-160
The Red Lakes in northwestern Minnesota comprise 275,000 acres of water which support a commercial fishery producing up to 1.5 million pounds of fish per year. Walleye, Stizostedion vitreum vitreum (Mitchill), and yellow perch, Perca flavescens (Mitchill), are the principal species. Statistics for the past 37 years have been analyzed...
Discussion of “expansion and increase in permeability of carbonate rocks on heating”
Clifford A. Kaye, John C. Maxwell, Peter Verrall
1953, Eos, Transactions, American Geophysical Union (34) 953-954
Maxwell and Verrall's interesting study raises a thought. If limestones expand on heating and thereby receive a permanent set, as this paper demonstrates, do we not have here a means of determining the maximum temperature to which a particular limestone was ever subjected and indirectly thereby its maximum depth of...
An epizootic among rainbow trout
1953, Progressive Fish-Culturist (15) 179-181
An epizootic among rainbow trout (Salmo gairdnerii) in a private trout farm, resulting from a species of Ichthyosporidium that caused very high mortality rates in all ages of trout, reported from the State of Washington....
Observations on gas-bubble disease of fish
1953, Progressive Fish-Culturist (15) 24-26
SOME DIFFICULTY has been experienced in raising fry and young fingerlings at the Puyallup hatchery of the Washington State Department of Game, a hatchery now in its fourth year of operation. There has been evidence of gas in the yolk-sac fry, and the mortality was always excessive among the fingerlings...
Trap efficiency of reservoirs
Gunnar M. Brune
1953, Eos, Transactions, American Geophysical Union (34) 407-448
Forty-four records of reservoir trap efficiency and the factors affecting trap efficiency are analyzed. The capacity-inflow (C/I) ratio is found to offer a much closer correlation with trap efficiency than the capacity-watershed (C/W) ratio heretofore widely used. It appears likely from the cases studied that accurate timing of venting or...
A contagious disease of salmon, possibly of virus origin
R.R. Rucker, W.J. Whipple, J.R. Parvin, C.A. Evans
1953, Fishery Bulletin (54) 35-46
Production records for 1885, 1891–1908, and 1929–49, indicate cyclic fluctuations for several important species of fish. The average annual take (all species) of 3,582,000 pounds in 1929–49 was 3,503,000 pounds below the 1891–1908 mean of 7,085,000 pounds. Decline in the output of lake herring alone from 5,841,000 pounds in 1891–1908...
Geology, of the High Climb Pegmatite, Custer County, South Dakota
Douglas M. Sheridan
1953, Trace Elements Investigations 231
The High Climb pegmatite, Custer County, S. Dak., belongs to the series of pegmatitic and granitic rocks that characterize the Harney Peak region of the southern Black Hills. It intrudes pre-Cambrian metamorphic rocks consisting chiefly of quartz-mica schist. The country rock has been altered to a tourmaline-rich schist along part...
Occurrences of uranium-bearing minerals in the St. Kevin District, Lake County, Colorado
C. T. Pierson, Q. D. Singewald
1953, Trace Elements Investigations 234
Two hundred and seventy-one prospect pits, mine dumps, or mine workings within the Sugar Loaf-St. Kevin mining districts and vicinity were tested for radioactivity by the U.S. Geological Survey in 1951 during six weeks of investigation on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission....
