Relationship between plantings of fry and production of whitefish in Lake Erie
John Van Oosten
1942, Transactions of the American Fisheries Society (71) 118-121
An attempt was made to substantiate the repeated assertions of the commercial fishermen on the Great Lakes and of others that there was a direct causal relationship between the plantings of whitefish fry and subsequent catch. The records of whitefish fry plantings in Lake Erie during the years, 1920–1937, were...
The oxidizing power of illinois coal. II. The effects of extended time
G. R. Yohe, M.H. Wilt
1942, Journal of the American Chemical Society (64) 1809-1811
The oxidizing power exhibited by five Illinois coals has been shown to reach a maximum value and then decrease, suggesting that this "reactive oxygen" may play the role of an intermediate in the oxidative degradation of these coals....
Use of phosphate for separation of cobalt from iron
V. North, R. C. Wells
1942, Industrial and Engineering Chemistry (14) 859-860
The well-known tendency of cobalt to be retained by the iron-alumina precipitate produced by ammonia has generally been ascribed to a specific adsorption by the large surface of this gelatinous precipitate. Whatever its cause, it can be overcome by precipitating the iron as phosphate at a pH of 3.5. The...
Determination of ash in coals unusually high in calcite and pyrite
O.W. Rees, W.A. Selvig
1942, Industrial and Engineering Chemistry (14) 209-212
The preliminary hearth heating method (A and E) gave results within the A. S. T. M. tolerances for all duplicates obtained in the same laboratory. Checks between different laboratories within A. S. T. M. tolerances were obtained for coals containing up to about 3.6 per cent mineral carbon dioxide, but...
Banded birds recovered in El Salvador
M.T. Cooke
1941, The Auk (58) 589-590
Three records of birds banded in the United States and recovered in El Salvador have recently been received and seem of sufficient importance to warrant immediate publication....
Notes on Costia Necatrix
F. F. Fish
1941, Transactions of the American Fisheries Society (70) 441-445
Costiasis, or the disease produced by the flagellated protozoan ectoparasite, Costia necatrix, is of considerable importance in the artificial propagation of both warm- and cold-water fishes. In spite of its importance, costiasis seldom is accurately diagnosed probably because of the extremely small size and sedentary nature of the causative organism....
