Lake Erie walleyes--again on the upswing?
Charles P. Seldon, Harry D. Van Meter
1960, Ohio Conservation Bulletin (24) 5-7
SUMMARY The effect of DDT dust on wildlife was studied at Camp Bullis, Bexar County, Texas, in the summer of 1947. Studies were made on a 206.6 acre plot that was treated with DDT for experimental control of the Lone Star tick (Amblyomrna americanum). A dust consisting...
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...
A primer on water
Luna Bergere Leopold, Walter Basil Langbein
1960, Report
When you open the faucet you expect water to flow. And you expect it to flow night or day, summer or winter, whether you want to fill a glass or water the lawn. It should be clean and pure, without any odor.You have seen or read about places where the...
The stoneroller, Campostoma anomalum (Rafinesque), in Great Smoky Mountains National Park
R. E. Lennon, P. S. Parker
1960, Transactions of the American Fisheries Society (89) 263-270
The stoneroller (Campostoma anomalum) is one of the more important fish in Great Smoky Mountains National Park because of its abundance and habits. Although esteemed locally as a food and a bait fish, the stoneroller is exploited but little since the fishing regulations which govern the utilization of game fishes...
The American Fisheries Society
James W. Moffett
1960, U.S. Trout News (5) 20-22
In the course of studies designed to determine the calcium and phosphorus requirements of breeding bobwhite quail, it was found that best results were obtained when the Ca/P ratio in the diet was approximately 2.3:1. Variations in the Ca/P ratio produced significant differences in results when the level of...
The vertical migration of Mysis relicta in Lakes Huron and Michigan
Alfred M. Beeton
1960, Journal of the Fisheries Research Board of Canada (17) 517-539
During the day Mysis relicta could be taken only near the bottom of Lakes Huron and Michigan. In the evening they migrated into the overlying strata as the surface light intensity decreased from 15 to 1 foot-candles. Frequently the mysids migrated through the metalimnion when first ascending, but later in the night...
Collection and preservation of fish and other materials exposed to pesticides
Oliver B. Cope
1960, Progressive Fish-Culturist (22) 103-108
The effects of pesticides on fish have become improtant to fish conservation since World War II, when DDT first came into common use. With the development of other potent insecticides and the increasing use of massive dosages in more recent years, the threat to fish and fish foods has increased....
Characteristic constants of 2,2',4'-trihydroxyazobenzene-5-sulfonic acid, a reagent for spectrophotometric analysis
Mary H. Fletcher
1960, Analytical Chemistry (32) 1822-1827
The dye 2,2',4'-trihydroxyazobenzene-5-sulfonic acid, has shown promise as a reagent for the determination of zirconium. As the literature contains very little information about this dye, basic data pertinent to its use as a reagent were determined. The sulfonic acid group and all three of the hydroxy groups show acidic characteristics....
Effect of FeS on the unit cell edge of sphalerite, a revision
Brian J. Skinner, P. B. Barton Jr., G. Kullerud
1959, Economic Geology (54) 1040-1046
Redeterminations of the relation between the composition and unit-cell size of Fe-bearing sphalerites, necessitated because of partial oxidation of the FeS sample used in earlier measurements, are presented. It is noted that the Fe-ZnS solvus curve may also require revision and should be used with caution, particularly for temperature determinations...
Dry diets for Chinook salmon
Walter E. Neilson, J. J. Mazuranich
1959, Progressive Fish-Culturist (21) 86-88
The purpose of this paper is to present the results obtained with seven different diets used as starting diets of chinook salmon fry....
Etiology of sockeye salmon 'virus' disease
Raymond W. Guenther, S.W. Watson, R.R. Rucker, A. J. Ross
1959, Special Scientific Report - Fisheries 296
Violent epizootics among hatchery reared sockeye salmon fingerlings (Oncorhynchus nerka) caused by a filterable agent have occurred. In 1954, one source of this infectious, filterable agent was found to be adult sockeye viscera used in the diet for the fingerlings. The results of observations on an epizootic in 1958 indicate...
Geological investigations in the U12b.03 and U12b.04 tunnels, Nevada Test Site
W.H. Diment, V. R. Wilmarth, F. A. McKeown, D.D. Dickey, E. N. Hinrichs, T. Botinelly, C. H. Roach, F. M. Byers, C. C. Hawley, G. A. Izett, Alfred Clebsch
1959, Trace Elements Memorandum 996
The papers comprising the various parts of this report contain preliminary results of the U. S. Geological Survey investigations in the U12b.03 and U12b.04 tunnels at the Nevada Test Site, Nye County, Nevada (fig. 1). The geologic studies were undertaken to define the structural, chemical, mineralogic, and some of the...
Gravity and seismic exploration in Yucca Valley, Nevada test site, January-April, 1959
William H. Diment, D.L. Healey, J.C. Roller
1959, Trace Elements Investigations 545
The thickness of the alluvial and tuffaceous deposits that overlie bedrock in Yucca Valley has been inferred from gravity and seismic measurements. Preliminary interpretations indicate that these deposits are thickest in a narrow north-trending trough in the eastern part of the valley. The gravity data delineate a buried north-trending ridge...
