Q-mode factor analysis of compositional data
A.T. Miesch
1976, Computers & Geosciences (1) 147-159
An extended form of the method of Q-mode factor analysis may be used if the rows of the data matrix sum to a constant. The constant row-sum provides a means for scaling the factor model to conform to the units of the original data in such forms as proportions, percentages,...
Myxosoma cerebralis: In vitro sporulation of the Myxosporidan of salmonid whirling disease
K. Wolf, M.E. Markiw
1976, Journal of Protozoology (23) 425-427
Trophozoites and other pre-spore stages of the myxosporidan Myxosoma cerebralis were taken from infected rainbow trout (Salmo gairdneri) and cultured in vitro. Cultures eventually yielded mature spores capable of discharging their polar capsules. This is the first report of culture of a myxosporidan....
Earthquake history of Pennsylvania
C. A. von Hake
1976, Earthquake Information Bulletin (USGS) (8) 28-31
Record of early earthquakes in Northeastern United States provide limited information on effects in pennsylvania until 1737, 55 years after the first permanent settlement was established. A very severe earthquake that centered in the St.Lawrence River region in 1663 may have been felt in Pennsylvania, but historical accounts are not...
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....
Geothermal energy in the United States; Part II, Assessment of resources
D.L. Williams
1976, Earthquake Information Bulletin (USGS) (8) 18-23
Geothermal energy-from heat deep inside the Earth- is a vast potential source of power. This article is the second part of a series on geothermal energy, the first part of which was in volume 8, number 1, of the Earthquake Information Bulletin (January-February 1976). Part 1 of this series described the...

Upland sandpiper nesting and management in North Dakota
L.M. Kirsch, K.F. Higgins
1976, Wildlife Society Bulletin (4) 16-20
Nests of 195 upland sandpipers (Bartramia longicauda) on the Missouri Coteau of North Dakota generally were well concealed by grassy vegetation which ranged from 15.4-30.8 cm in height. Nest densities ranged from 0.3 per 40.5 ha on annually tilled croplands to 6.8 per 40.5 ha on native grasslands during the...
Plasma luteinizing hormone and the development of ovarian follicles after loss of clutch in female mallards (Anas platyrhynchos)
R.S. Donham, C.W. Dane, D. S. Farner
1976, General and Comparative Endocrinology (29) 152-155
The plasma level of LH and the extent of development of ovarian follicles were analyzed in incubating female Mallards. In both wild and game-farm stock, incubation was associated with a significant decline in plasma levels of LH from those of laying females. Within 1 day after removal of eggs, LH...
Antimycin: Uptake, distribution, and elimination in brown bullheads (Ictalurus nebulosus)
D.P. Schultz, P.D. Harman
1976, Journal of the Fisheries Research Board of Canada (33) 1121-1129
Radioactive antimycin was readily taken up in bile and tissues of brown bullheads (Ictalurus nebulosus) exposed to 0.045 μg/ml of 14C-antimycin for as long as 48 h. Bile contained the most and blood the least radioactivity at all sampling periods. The highest concentration of 14C-antimycin in muscle was 0.12 μg/g, after 12 h of exposure. The...
The California poppy (eschscholtzia mexicana) as a copper indicator plant - A new example
M.A. Chaffee, C.W. Gale III
1976, Journal of Geochemical Exploration (5) 59-63
The abundance and distribution of the California poppy (Eschscholtzia mexicana) correlates closely with the copper-rich outcrop of a small porphyry-type deposit in Arizona. Chemical factors are probably more important than physical factors in determining why this species is sometimes found as a copper indicator plant....
Late Pleistocene and Holocene depositional trends, processes, and history of Astoria deep-sea fan, Northeast Pacific
H. Nelson
1976, Marine Geology (20) 129-173
The asymmetrical Astoria Fan (110 × 180 km) developed off the Columbia River and Astoria submarine canyon during the Pleistocene. Morphology, stratigraphy, and lithology have been outlined for a Pleistocene turbidite, and a Holocene hemipelagic sedimentary regime to generate geologically significant criteria for comparison with ancient equivalent deposits. Both gray...
Mercurian volcanism questioned
D.E. Wilhelms
1976, Icarus (28) 551-558
The Mariner 10 television team has argued that extensive plains on Mercury were formed by volcanism and compared them with the demonstrably lunar maria. I believe, however, that in stratigraphic relations, surface morphology, and albedo contrast, the Mercurian plains more closely resemble the lunar light plains. These lunar plains were...
Constant potential pulse polarography
J. H. Christie, Larry L. Jackson, R. A. Osteryoung
1976, Analytical Chemistry (48) 561-564
The new technique of constant potential pulse polarography, In which all pulses are to be the same potential, is presented theoretically and evaluated experimentally. The response obtained is in the form of a faradaic current wave superimposed on a constant capacitative component. Results obtained with a computer-controlled system exhibit a...
Additional evidence of Mercurian volcanism
N.J. Trask, R.G. Strom
1976, Icarus (28) 559-563
Evidence concerned with (1) the character and distribution of terrain surrounding fresh basins, (2) albedo, color and temporal differences between a basin rim and smooth plains on its floor, and (3) the stratigraphic relations and local distribution of smooth plains in the hilly and lineated terrain are cited as additional...
Morphologic interpretation of fertile structures in glossopterid gymnosperms
J. M. Schopf
1976, Review of Palaeobotany and Palynology (21) 25-64
The problem of determining affinity among glossopterid gymnosperms is beset by deficiencies in preservation, natural dissociation of parts, and scarcity of features assuredly critical for morphologic comprarison. The glossopterids probably are not a very heterogeneous group of plants, but this is difficult to prove. The Gondwana glacial "hiatus" has resulted...
Influence of water temperature on gill sodium, potassium-stimulated ATPase activity in juvenile coho salmon (Oncorhynchus kisutch)
W.S. Zaugg, L. R. McLain
1976, Comparative Biochemistry and Physiology, Part A: Physiology (54) 419-421
1. Gill sodium, potassium-stimulated ATPase activity was determined from December to July in gills of yearling coho salmon (Oncorhynchus kisutch) maintained at four temperatures, 6, 10, 15 and 20°C.2. Compared to fish held at 6°C, elevation in ATPase activity and the associated parr-smolt transformation were accelerated in fish at...
