The oxidizing power of illinois coal. I. The reaction with titanous chloride
G.R. Yoke, C. Alex Harman
1941, Journal of the American Chemical Society (63) 555-556
Illinois coals which have been exposed to air or oxygen show a small but definite ability to oxidize titanous chloride. This oxidizing power is gained very rapidly when freshly ground coal is exposed to air. Neither the magnitude nor the rapid increase of this oxidizing power can be accounted for...
Age and growth of the rock bass, Ambloplites rupestris (Rafinesque), in Nebish Lake, Wisconsin
Ralph Hile
1941, Transactions of the Wisconsin Academy of Sciences, Arts, and Letters (33) 189-337
The present study of the age and growth of the Nebish Lake rock bass is another in a series of papers that have been based wholly or in part on materials collected in the course of investigations on the fishes of the lakes of the northeastern highlands, Wisconsin, conducted cooperatively...
Bathymetric distribution of fish in lakes of the northeastern highlands, Wisconsin
Ralph Hile, Chancey Juday
1941, Transactions of the Wisconsin Academy of Sciences, Arts, and Letters (33) 147-187
The present study of the bathymetric distribution of fish in the lakes of northeastern Wisconsin has been based on records of the catches of gill nets fished during the summers of 1930, 1931 and 1932. During the first of the three summers, soundings were made only of the general area...
Age, growth, and production of the yellow perch, Perca flavescens (Mitchill), of Saginaw Bay
Ralph Hile, Frank W. Jobes
1941, Transactions of the American Fisheries Society (70) 102-122
Ages were determined and individual growth histories computed from the examination and measurement of scales from 820 yellow perch collected in 1929 and 1930. Calculated lengths greater than 101 millimeters were computed on the assumption (supported by empirical data) that the ratio of body length to scale length is constant....
Determination of small quantities of fluoride in water: A modified zirconium-alizarin method
W.L. Lamar, C.G. Seegmiller
1941, Industrial And Engineering Chemistry Analytical Edition (13) 901-902
The zirconium-alizarin method has been modified to facilitate the convenient and accurate determination of small amounts of fluoride in a large number of water samples. Sulfuric acid is used to acidify the samples to reduce the interference of sulfate. The pH is accurately controlled to give the most sensitive comparisons....
