Reservoir processes and fluid origins in the Baca geothermal system, Valles Caldera, New Mexico
A.H. Truesdell, C. J. Janik
1986, Journal of Geophysical Research Solid Earth (91) 1817-1833
At the Baca geothermal field in the Valles caldera, New Mexico, 19 deep wells were drilled in an attempt to develop a 50-MWe (megawatts electric) power plant. The chemical and isotopic compositions of steam and water samples have been used to indicate uniquely the origin of reservoir fluids and natural reservoir...

Adaptation of Selenastrum capricornutum (Chlorophyceae) to copper
J.S. Kuwabara, H.V. Leland
1986, Environmental Toxicology and Chemistry (5) 197-203
Selenastrum capricornutum Printz, growing in a chemically defined medium, was used as a model for studying adaptation of algae to a toxic metal (copper) ion. Cells exhibited lag‐phase adaptation to 0.8 μM total Cu (10−12 M free ion concentration) after 20 generations of Cu exposure. Selenastrum adapted to the same...
Effects of shrub coverages on birds of North Dakota mixed-grass prairies
T.W. Arnold, K.F. Higgins
1986, Canadian Field-Naturalist (100) 10-14
We studied the distribution and density of passerine birds in relation to Wolfberry (Symphoricarpos occidentalis) and Silverberry (Elaeagnus commutata) shrub coverages on mixed-grass prairies of central North Dakota. Birds were counted along shrubby and shrubless transects during the 1982 breeding season. Species richness and total density of birds were greater...

A comparison of burn season effects on nesting birds in North Dakota mixed-grass prairie
K.F. Higgins
1986, Prairie Naturalist (18) 219-228
During 1982-1985, the effects of single spring and fall burn treatments on ground nesting birds and residual cover were studied on five paired areas of native mixed-grass prairie in northwestern Stutsman County, ND. Annually, visual obstruction readings to index the height-density of residual cover were taken once and nest searches...

The Valley and Ridge Province of eastern Pennsylvania - Stratigraphic and sedimentologic contributions and problems
Jack B. Epstein
1986, Geological Journal (21) 283-306
Many contributions that have led to a better understanding of Appalachian geology have resulted directly from work in the folded Appalachian Mountain and Great Valley sections of the Valley and Ridge physiographic province of eastern Pennsylvania. Disagreements have been common since H.D. Rogers first described the geology of the area...
The heat capacity of a natural monticellite and phase equilibria in the system CaO-MgO-SiO2-CO2
Z.D. Sharp, E.J. Essene, Lawrence M. Anovitz, G.W. Metz, E.F. Westrum Jr., B. S. Hemingway, J.W. Valley
1986, Geochimica et Cosmochimica Acta (50) 1475-1484
The heat capacity of a natural monticellite (Ca1.00Mg.09Fe.91Mn.01Si0.99O3.99) measured between 9.6 and 343 K using intermittent-heating, adiabatic calorimetry yields Cp0(298) and S2980 of 123.64 ± 0.18 and 109.44 ± 0.16 J · mol−1K−1 respectively. Extrapolation of this entropy value to end-member monticellite results in an S0298 = 108.1 ±...
A numerical investigation of head waves and leaky modes in fluid- filled boreholes
Frederick L. Paillet, C.H. Cheng
1986, Geophysics (51) 1438-1449
Although synthetic borehole seismograms can be computed for a wide range of borehole conditions, the physical nature of shear and compressional head waves in fluid-filled boreholes is poorly understood. This paper presents a series of numerical experiments designed to explain the physical mechanisms controlling head-wave propagation in boreholes. These calculations...

Inclusion body disease of cranes: Comparison of pathologic findings in cranes with acquired vs. experimentally induced disease
J. C. Schuh, L. Sileo, Lynne M. Siegfried, Thomas M. Yuill
1986, Journal of the American Veterinary Medical Association (189) 993-996
Inclusion body disease of cranes was the cause of death in 17 immature and mature cranes of 5 different species in Wisconsin. A herpesvirus of unknown origin was the apparent cause. An isolate of this herpesvirus was used to experimentally infect 3 species of cranes. Macroscopic and microscopic lesions associated...
Comments on 'Remarks on the secular change in the energy density spectrum of the geomagnetic field' by Joachim Meyer.
L.R. Alldredge
1986, Journal of Geomagnetism & Geoelectricity (38) 171-172
Meyer has discussed only the Rn aspect of the Alldredge (1984) paper he is criticising. He has ignored the pictorial demonstration of the need for higher harmonics to properly describe the secular variation field than the main field as demonstrated. This more or less independent demonstration supports the general conclusion...
