Description: The procaryotic photosynthetic microorganisms Anacystis nidulans, Nostoc and Rhodospirillum rubrum have cell walls and membranes that are resistant to the solution of methane in their lipid components and intracellular fluids. But Anacystis nidulans, possesses a limited bioxidant system, a portion of which may be extracellularly secreted, which rapidly oxidizes methane to carbon dioxide. Small C{sup 14} activities derived from CH{sub 4} in excess of experimental error are detected in all the major biochemical fractions of Anacystis nidulans and Nostoc. This limited capacity to metabolize methane appears to be a vestigial potentiality that originated over two billion years ago in the early evolution of photosynthetic bacteria and blue-green algae.

Survey of Piledriver results and preliminary interpretation of three postshot cores in and near the cavity

Description: A summary of measured data collected by numerous agencies cooperating in the Piledriver event, is presented together with calculations based on empirical relations deduced from past events in comparable media. Of 9 relations that have been proposed to predict cavity radius, 5 result in radii accurate to <3.5%. The remainder are off by about 10 to 18%. Three postshot recovered cores (U-15.01 PS-1, -2, -3) were examined on a gross scale prior to extensive detailed sampling for laboratory tests. The positions of injected glass seams, radioactivity, and shear zones were recorded. The orientation of several thousand core fractures was measured with respect to the core axes and distance from the shot point. Taking all observations into account, phenomena related to failure of rock is the Piledriver event are closely related to pre-existing weaknesses and inhomogeneities. (Longer abstract available)

Supply and Demand for Energy in the United States by States and Regions, 1960 and 1965: Integrated Energy Balances and Energy Flows (Prepared from Four Parts)

Description: Report issued by the U.S. Bureau of Mines discussing state and regional supply and demand data. Integrated energy balances and energy flows are presented and used "to produce, transform, and transport energy to the point of consumption" (p. 1). This report includes maps, tables, and illustrations.
