The Talas-Fergana Fault, Kirghiz and Kazakh, USSR
R. E. Wallace
1976, Earthquake Information Bulletin (USGS) (8) 4-13
The great Talas-Fergana fault transects the Soviet republic of Kirghiz in Soviet Central Asia and extends southeastward into China and northwestward into Kazakh SSR (figs. 1 and 2). This great rupture in the Earth's crust rivals the San Andreas fault in California; it is long (approximately 900 kilometers), complex, and...
Conditions in the deeper parts of the hot spring systems of Yellowstone National Park, Wyoming
Alfred Hemingway Truesdell, Robert O. Fournier
1976, Open-File Report 76-428
Yellowstone thermal areas are scattered over an area of nearly 50 x 60 kilometers (Fig. 1) and contain waters of diverse compositions. This has lead to the implicit assumption that Yellowstone consisted of discrete hydrothermal systems (e.g., Fournier and Truesdell, 1970). It is the purpose of this paper to suggest...

1976, Seismological Research Letters (8) 18-22
The revised “Earthquake Report” questionnaire introduced here is designed to restrict the replies on the effects of earthquakes as closely as possible to a set of effects that can be evaluated by use of a computer program. Differences in intensity resulting from evaluation by different individuals using their own qualitative...
Prevention and control of viral diseases of salmonids
Donald F. Amend
1976, Journal of the Fisheries Research Board of Canada (33) 1059-1066
Three viral diseases of salmonids are of worldwide concern: infectious pancreatic necrosis (IPN) viral hemorrhagic septicemia (VHS), and infectious hematopoietic necrosis (IHN). Six principal approaches are being used to prevent or control these diseases: 1) preventing contact o the pathogen with the host, 2) environmental manipulation, 3) immunization, 4) chemotherapy,...
Earthquakes June-July 1976
W. J. Person
1976, Earthquake Information Bulletin (USGS) (8) 31-33
This was a seismically active period, with one great earthquake, four major earthquakes, and several strong shocks worldwide. Many persons were killed and thousands were injured in three separate events-in West Irian (west New Guinea), in Bali, Indonesia, and in northeastern China. A great earthquake (one with a Richter magnitude 8.0...
Simulation of streamflow of Flambeau River at Park Falls, Wisconsin to define low-flow characteristics
William R. Krug
1976, Water-Resources Investigations Report 76-116
Daily streamflows of the Flambeau River at Park Falls, Wisconsin , were simulated for a 31-year period. Streamflow was simulated using a streamflow-routing model. These simulated daily flows were analyzed for summer (June 1-October 31) low-flow frequency. The resultant 7-day, 10-year summer low flow is 260 cubic feet per second....

1976, Geochimica et Cosmochimica Acta (40) 1031-1049
At Naxos, Greece, a migmatite dome is surrounded by schists and marbles of decreasing metamorphic grade. Sillimanite, kyanite, biotite, chlorite, and glaucophane zones are recognized at successively greater distances from the migmatite dome. Quartz-muscovite and quartz-biotite oxygen isotope and mineralogie temperatures range from 350 to 700°C.The metamorphic complex can be...
Allantoinase in the marine polychaete Eudistylia vancouveri
Dora R. M. Passino, G.W. Brown Jr.
1976, Experientia (32) 1376-1377
Allantoinase, an enzyme in the purine-urea cycle, was found in Eudistylia vancouveri (Polychaeta). The enzyme had a pH optimum at 7.6. The Km was 0.012 M allantoin, and the Arrhenius energy of activation was 12.6 to 14.6 kcal/mol....
An acute septicaemic disease of brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) caused by a Pasteurella-like organism
T. Hastein, G. L. Bullock
1976, Journal of Fish Biology (8) 23-26
Ulcerations of the skin associated with haemorrhagic petechiae of liver and kidneys, were the main signs of disease affecting salmon and brown trout in Norway. A death rate of 15–20% was estimated for the 5 month period of mid-March-August, although mortalities occurred throughout the year. Bacteriological examinations, involving 36 isolates,...
Utilization of satellite data for inventorying prairie ponds and lakes
E.A. Work, D.S. Gilmer
1976, Photogrammetric Engineering and Remote Sensing (42) 685-694
By using data acquired by LANDSAT-1 (formerly ERTS- 1), studies were conducted in extracting information necessary for formulating management decisions relating to migratory waterfowl.

Disharmony of the spheres: Recent trends in planetary surface nomenclature
R.J. Pike
1976, Icarus (27) 577-583
Inadvisable departures from tradition in naming newly mapped features on Mars, Mercury, and the Moon have been implemented and proposed since 1970. Functional need for place names also has become confused with cartographic convenience. Much of the resulting new nomenclature is neither unique, efficient, nor imaginative. The longstanding classical orientation...
