A comparison of radiative capture with decay gamma-ray method in bore hole logging for economic minerals
F. E. Senftle, R.M. Moxham, A.B. Tanner
1972, Nuclear Instruments and Methods (104) 485-492
The recent availability of borehole logging sondes employing a source of neutrons and a Ge(Li) detector opens up the possibility of analyzing either decay or capture gamma rays. The most efficient method for a given element can be predicted by calculating the decay-to-capture count ratio for the most prominent peaks...
Prospects for earthquake prediction and control
J. H. Healy, W.H.K. Lee, L. C. Pakiser, C.B. Raleigh, M.D. Wood
1972, Tectonophysics (14) 319-332
The San Andreas fault is viewed, according to the concepts of seafloor spreading and plate tectonics, as a transform fault that separates the Pacific and North American plates and along which relative movements of 2 to 6 cm/year have been taking place. The resulting strain can be released by creep,...

Oceanic ridges and transform faults: Their intersection angles and resistance to plate motion
A.H. Lachenbruch, G. A. Thompson
1972, Earth and Planetary Science Letters (15) 116-122
The persistent near-orthogonal pattern formed by oceanic ridges and transform faults defies explanation in terms of rigid plates because it probably depends on the energy associated with deformation. For passive spreading, it is likely that the ridges and transforms adjust to a...

The relation of turbulence to diffusion in open-channel flows
Thomas N. Keefer
1971, Open-File Report 72-206
This investigation examines the interrelation between turbulent diffusion, dispersion, and the statistical properties of turbulence in an open-channel flow. The experiments were conducted in a 3. 87- foot wide flume over four boundary roughnesses. The results are from studies made of: (1) the influence of turbulence on the vertical and...

Techniques for assessing water resource potentials in the developing countries: with emphasis on streamflow, erosion and sediment transport, water movement in unsaturated soils, ground water, and remote sensing in hydrologic applications
George C. Taylor Jr.
1971, Open-File Report 72-375
Hydrologic instrumentation and methodology for assessing water-resource potentials have originated largely in the developed countries of the temperature zone. The developing countries lie largely in the tropic zone, which contains the full gamut of the earth's climatic environments, including most of those of the temperate zone. For this reason, most...
Thermal study of the Missouri River in North Dakota using infrared imagery
Orlo A. Crosby
1971, Open-File Report 71-81
Studies of infrared imagery obtained from aircraft at 305- to 1,524- meter altitudes indicate the feasibility of monitoring thermal changes attributable to the operation of thermal-electric plants and storage reservoirs, as well as natural phenomena such as tributary inflow and ground-water seeps, in large rivers. No identifiable sources of ground-water...
