Choice of working fluid and operating conditions for energy conversion with geothermal heat sources

Description: A study of electric power generating cycles which can be used in conjunction with a low-temperature geothermal energy (sensible heat) source is presented. Investigators at Los Alamos Scientific Laboratory have proposed a steam/isobutane dual cycle capable of generating 50.7 Mw of electric power. This cycle is optimized using regenerative feed water heating to yield a power output of 52.1 Mw or an improvement of 2.8%. Other power cycle designs and working fluids are investigated. Working fluids … more

Effect of a bridge balance network on a semiconductor pressure transducer

Description: Pressure transducers and accelerometers that make use of semiconductors strain gages or have strain gages diffused on a silicon diaphragm cannot be used with a bridge balance network if one wants to achieve thermal zero compensation. Thermal zero compensation is compensating for the change in output due to temperature only, and is typically +-1.5 percent of the full scale output for a temperature change of 100/sup 0/F. The reason for not using a balance network is the way in which the transduce… more

Secondary succession: Composition of the vegetation and primary production in the field-to-forest at Brookhaven, Long Island, N.Y.

Description: Natural communities respond to disruption through a series of changes in plant and animal communities that are broadly predictable. The field-to-forest sere of central Long Island follows the pattern set forth earlier for the Piedmont of North Carolina and for New Jersey. The communities of herbs that occur in the years immediately after abandonment are followed by an Andropogon stage which is replaced before the 20th year by pine forest. The pine is replaced in the next 25 years by oak-pine, w… more

Phases of resonant amplitudes: {pi}N {Yields} {pi}{delta}

Description: The phases of resonant amplitudes in pi N yields pi DELTA are studied in a modified version of SU(6)w in which amplitudes involving different relative orbital angular momenta l are uncoupled from one another. This form of SU(6)/sub W/ is equivalent to one studied recently by Melosh, in which the set of selection rules for decays is extended to allow for more types of transition than in the original version of this symmetry. The predictions are compared with a recent preliminary analysis by Hern… more
