Selected topics of fluid mechanics
Carl E. Kindsvater
1958, Water Supply Paper 1369-A
The fundamental equations of fluid mechanics are specific expressions of the principles of motion which are ascribed to Isaac Newton. Thus, the equations which form the framework of applied fluid mechanics or hydraulics are, in addition to the equation of continuity, the Newtonian equations of energy and momentum. These basic...

The environmental control of sedimentary iron minerals
N.K. Huber
1958, Economic Geology (53) 123-140
An Eh-pH stability diagram is developed for hematite, magnetite, siderite, pyrite, and iron sulfide that indicates the relative position of their stability fields in a normal sea water system. With the exception of the magnetite-siderite relationship, Eh is much more critical than pH. In general terms, hematite is stable under...
The solusphere - its inferences and study
F. H. Rainwater, W. F. White
1958, Geochimica et Cosmochimica Acta (14) 244-249
Water is a fundamental geologic agent active in rock decomposition, erosion, and synthesis. Solutes in water are of particular interest to geochemists as sources of raw material for synthesis or as products of decomposition. When geochemical studies move from the laboratory into natural environment many variables relating to solute hydrology...
Reconnaissance study of erosion and deposition produced by the flood of August 1955 in Connecticut
M. Gordon Wolman, J.P. Eiler
1958, Eos, Transactions, American Geophysical Union (39) 1-14
A large area in the valley bottoms in Connecticut was inundated by the flood of August 1955. Relative to the total area flooded that part permanently modified by the flow was surprisingly small. Although great in some places, the distribution of these permanent modifications of channel and flood plain was...
Mass control of insects: The effects on fish and wildlife
Oliver B. Cope, Paul F. Springer
1958, Bulletin of the Entomological Society of America (4) 52-56
The mass control of insects carried on during the past ten years has made possible the economical suppression and, in a few instances, the near eradication of pest insect populations over widespread areas. These large operations, usually featuring the use of the airplane for applying insecticides quickly and cheaply, have...
A combined deamination and nitro reduction method for nitroanilines
G. C. Finger, R.H. White
1958, Journal of Organic Chemistry (23) 1612-1613
The hypophosphorous acid-cuprous oxide deamination method on nitroanilines has been modified so that the nitro compounds which are formed are reduced in turn by cuprous oxide to the corresponding amines. Over-all yields of 55-65% are reported for three halogenated nitroanilines....
The deuterium content of water in some volcanic glasses
I. Friedman, R. L. Smith
1958, Geochimica et Cosmochimica Acta (15) 218-228
The deuterium-hydrogen composition (relative to Lake Michigan water = 0.0) of water extractsd from coexisting perlite and obsidian from eleven different localities was determined. The water content of the obsidians is generally from 0.09 to 0.29 per cent by weight, though two samples from near Olancha, California, contain about 0.92...
Volumes and surface areas of pendular rings
W. Rose
1958, Journal of Applied Physics (29) 687-691
A packing of spheres is taken as a suitable model of porous media. The packing may be regular and the sphere size may be uniform, but in general, both should be random. Approximations are developed to give the volumes and surface areas of pendular rings that exist at points of sphere...
New host and locality record for Triaenophorus crassus forel (Cestoda: pseudophyllidea)
J. R. Uzmann, M. N. Hesselholt
1957, Journal of Parasitology (43) 205-208
The adult form of Triaenophorus crassus Forel, 1868 (= T. robustus Olsson, 1893; = T. tricuspidatus morpha megadentatus Wardle, 1932) occurs as an intestinal parasite in the pike, Esox lucius L., a holarctic species of wide distribution. Preliminary life-history stages include procercoid development in copepods of the genus Cyclops followed...
Uraniferous coal and carbonaceous shale in northeast Parana, Brazil
Donald D. Haynes, Charles T. Pierson
1957, Trace Elements Memorandum 1097
Uraniferous coal has been found in northeast Parana, Brazil, in the Rio Bonito formation of Pennsylvanian age. In the majority of coal samples taken the uranium oxide content ranges from 0.005 to 0.030 percent, but selected screened samples have contained as much as 0.445 percent uranium oxide. The sampled thickness...
