Tables for simplifying calculations of activities produced by thermal neutrons
F. E. Senftle, W.R. Champion
1954, Il Nuovo Cimento (12) 550-571
The method of calculation described is useful for the types of work of which examples are given. It is also useful in making rapid comparison of the activities that might be expected from several different elements. For instance, suppose it is desired to know which of the three elements, cobalt,...
A comparative study of 28 culture media for Trichomonas gallinae
L. S. Diamond
1954, Experimental Parasitology (3) 251-258
1. 1. A study was made of the ability of 28 different culture media to support growth of 5 strains of Trichomonas gallinae with their normally associated bacteria. A standard inoculum of 50 protozoa was used, and the cultures were incubated at 35 ?C. Based upon the number of positive...
Rodent repellents, preparation and properties of thiouronium compounds and cyclic imides
E. Bellack, J.B. DeWitt
1954, Journal of Agricultural and Food Chemistry (2) 1176-1179
Syntheses and bioassays of cyclic imides and thiouronium compounds were carried out as part of a search for materials capable of preventing rodent damage to packaged commodities. Previous studies had shown that repellent activity was associated with functional groups containing nitrogen and sulfur, and was enhanced by the presence...
Exploration for uranium deposits in the Atkinson Mesa area, Montrose County, Colorado
Daniel Allen Brew
1954, Trace Elements Investigations 290
The U.S. Geological Survey explored the Atkinson Mesa area for uranium- and vanadium-bearing deposits from July 2, 1951, to June 18, 1953, with 397 diamond-drill holes that totaled 261,251 feet. Sedimentary rocks of Mesozoic age are exposed in the Atkinson Mesa area. They are: the Brushy Basin member of the...
Uranium-bearing lignite and its relation to the White River and Arikaree formations in northwestern South Dakota and adjacent states
N.M. Denson, G.O. Bachman, H. D. Zeller
1954, Trace Elements Investigations 467
In northwestern South Dakota and adjacent areas uranium-bearing lignite beds occur at many horizons in the Hell Creek formation of late Cretaceous age and the overlying Ludlow, Tongue River, and Sentinel Butte members of the Fort Union formation of Paleocene age. Uranium analyses of 275 surface and auger samples and...
Uranium deposits in Fall River County, South Dakota
Henry Bell III, W.E. Bales
1954, Trace Elements Investigations 297
In 1951 uranium deposits contained carnotite were discovered in the southern Black Hills near Edgemont, Fall River County, S. Dak. Numerous carnotite deposits have since been found in sandstones in the Inyan Kara group of early Cretaceous age, and uranium-bearing material has been discovered in the Pennsylvania Minnelusa sandstone of...
Reconnaissance for radioactive deposits in the Hyder district, southeastern Alaska, 1949
Walter S. West, Paul D. Benson
1954, Trace Elements Investigations 73
Radioactivity reconnaissance during 1949 in the Hyder district, southeastern Alaska, revealed that radioactive material is widely distributed on the Mountain View property. However, no uranium deposits of commercial value were found in the restricted parts of the district covered by this investigation. Anomalous radioactivity was detected at a number of localities...
A postglacial chronology for some alluvial valleys in Wyoming
Luna Bergere Leopold, John P. Miller
1954, Water Supply Paper 1261
Alluvial terraces were studied in several major river basins in eastern Wyoming. Three terraces are present along nearly all the streams and large tributaries. There are several extensive dissected erosion surfaces in the area, but these are much older than, and stand well above, the recent alluvial terraces with which...
Uranophane at Silver Cliff mine, Lusk, Wyoming
Verl R. Wilmarth, Douglas H. Johnson
1954, Bulletin 1009-A
The uranium deposit at the Silver Cliff mine near Lusk, Wyo., consists primarily of uranophane which occurs as fracture fillings and small replacement pockets in faulted and fractured calcareous sandstone of Cambrian (?) age. The country rock in the vicinity of the mine is schist of pre-Cambrian age intruded by...
