Effects of selective fusion on the thermal history of the earth's mantle
W.H.K. Lee
1968, Earth and Planetary Science Letters (4) 270-276
A comparative study on the thermal history of the earth's mantle was made by numerical solutions of the heat equation including and excluding selective fusion of silicates. Selective fusion was approximated by melting in a multicomponent system and redistribution of radioactive elements. Effects of selective fusion on the thermal models...
Turnover and urinary excretion of free and acetylated MS-222 rainbow trout, Salmo gairdneri
J. B. Hunn, R.A. Schoettger, W. A. Willford
1968, Journal of the Fisheries Research Board of Canada (25) 25-31
Rainbow trout (Salmo gairdneri) anesthetized in 100 mg/liter of M.S. 222 at 12 C excreted the drug in free and acetylated forms via the urine during a 24-hr recovery period in freshwater. Of the M.S. 222 excreted, 77-96% was acetylated. Blood levels of free drug in anesthetized trout approximated 75%...
A surface tow net for collection of parasitic-phase sea lampreys
Frederick H. Dahl
1968, Progressive Fish-Culturist (30) 183-184
A STUDY OF MIGRATORY BEHAVIOR of parasitic sea lampreys (Petromyzon marinus) in the Great Lakes required a means of capturing lampreys for tagging and releasing in St. Marys River, Lake Huron. Smith and Elliott (1953) fished specially made gill and trap nets for sea lampreys, but stationary nets could not...
Silver-bearing black calcite in western mining districts
D. F. Hewett, A. S. Radtke
1967, Economic Geology (62) 1-21
The name black calcite has been applied from time to time to a dark gray to black variety of calcite or aragonite in metalliferous ore deposits in the Western States. Most of the material shows curved, roughly rhombic cleavage. The color is due to dispersed minute grains of one or...
