Advanced materials for alternative fuel capable directly fired heat engines
The first conference on advanced materials for alternative fuel capable directly fired heat engines was held at the Maine Maritime Academy, Castine, Maine. It was sponsored by the US Department of Energy, (Assistant Secretary for Fossil Energy) and the Electric Power Research Institute, (Division of Fossil Fuel and Advanced Systems). Forty-four papers from the proceedings have been entered into EDB and ERA and one also into EAPA; three had been entered previously from other sources. The papers are concerned with US DOE research programs in this area, coal gasification, coal liquefaction, gas turbines, fluidized-bed combustion and the materials used in these processes or equipments. The materials papers involve alloys, ceramics, coatings, cladding, etc., and the fabrication and materials listing of such materials and studies involving corrosion, erosion, deposition, etc. (LTN)

Interpretation of well log data from four drill holes at Roosevelt Hot Springs KGRA
Well logs from four drill holes, Utah State Geothermal Wells 14-2, 52-21 and 72-16 and Geothermal Power Corporation's thermal gradient hole GPC-15 have been digitized, plotted and studied. This study had three objectives: (1) to present the well log data in a convenient format for easy study, (2) to determine the nature of the geothermal reservoir rock and fluid properties, and (3) to make some inference on fluid entry locations in the boreholes and their effect on heat flow. The temperature logs and gradients computed from these logs have been used to examine heat flow in the vicinity of the four drill holes. Assumed and calculated thermal conductivities have been used in the analyses, 4 mcal/cm /sup 0/C sec for the alluvium and 7 mcal/cm /sup 0/C sec for the crystalline rocks. The data indicate that 14-2 and 72-16 reside in a dominantly convective heat flow environment, whereas GPC-15 and 52-21 reside in a dominantly conductive heat flow environment. The convective regions are believed to be fracture controlled and only portions of each hole reside totally in a convective region; in each case it is the upper bedrock portion of the hole. In every case the alluvium or upper portion …

Dominance of Strong Absorption in 9Be + 28Si Elastic Scattering
The elastic scattering of {sup 9}Be + {sup 28}Si has been measured at laboratory energies of 121.0 and 201.6 MeV. These data have been combined with existing lower energy {sup 9}Be + {sup 28}Si data in order to carry out a global optical model analysis. Calculations employing Woods-Saxon potentials yield good fits to the data without requiring explicitly energy-dependent parameters. In contrast, using a proximity form for the real potential requires an explicitly energy dependent Woods-Saxon imaginary potential in order to achieve comparable quality fits. Notch perturbation calculations have been utilized to locate the radial region of the potential to which the scattering is sensitive. At all energies the imaginary potential is stronger than the real potential at the radius of maximum sensitivity. This dominance of the absorptive potential greatly limits the amount of information which can be gained about the real potential. Comparison of the {sup 9}Be + {sup 28}Si system with other light heavy ion systems such as {sup 6}Li + {sup 28}Si, {sup 12}C + {sup 28}Si, and {sup 16}O + {sup 28}Si suggests that the weak binding of {sup 9}Be may be responsible for the strong absorption in this case.

Geology and alteration of the Baltazor Hot Springs and Painted Hills Thermal Areas, Humboldt County, Nevada
The Baltazor Hot Springs KGRA and nearby Painted Hills thermal area are situated in Humboldt County, northwestern Nevada along the northwestern margin of the Basin and Range province. The oldest rocks exposed in the Baltazor area are eugeosynclinal metasedimentary and subordinate metavolcanic rocks of Permian to Triassic age intruded by Cretaceous diorite and quartz diorite. These are overlain by a thick volcanic and volcaniclastic sequence of Miocene through Pliocene age. Pre-Tertiary rocks are not exposed in the Painted Hills. Principal structures in the Baltazor area are intersecting high-angle normal faults which trend northerly and northwesterly. Quaternary landslides are dominant in the Painted Hills, although northerly- and northwesterly-trending high-angle faults are also present. Hydrothermal alteration and mineralization at Baltazor and in the Painted Hills are of several different styles and ages. Copper-bearing quartz veins in pre-Tertiary rocks antedate Cenozoic volcanism and sedimentation. The heat source for thermal phenomena and alteration in both areas is probably deep fault-controlled fluid circulation coupled with an abnormally high regional thermal gradient. (MHR)

CHROMOPEPTIDES FROM PHYTOCHROME. THE STRUCTURE AND LINKAGE OF THE P{sub R} FORM OF THE PHYTOCHROME CHROMOPHORE
The isolation and chromatographic purification of chromophore-containing peptides from the P{sub R} form of phytochrome treated with pepsin and thermolysin are described. From the amino acid sequence and {sup 1}H NMR spectral analysis of phytochromobiliundeca peptide (2) , the structure of the P{sub R) phytochrome chromophore and the nature of the thioether linkage joining pigment to peptide have been established. Confirmatory evidence was obtained from similar analysis of phytochromobilioctapeptide (3) . The implications of this structural assignment with respect to the mechanism of the P{sub R} to P{sub FR} phototransformation is considered.

Calculated Thermally Induced Displacements and Stresses for Heater Experiments at Stripa, Sweden. Linear Thermoelastic Models Using Constant Material Properties
Thermally induced displacements and stresses have been calculated by finite element analysis to guide the design, operation, and data interpretation of the in situ heating experiments in a granite formation at Stripa, Sweden. There are two full-scale tests with electrical heater canisters comparable in size and power to those envisaged for reprocessed high level waste canisters and a time-scaled test. To provide a simple theoretical basis for data analysis, linear thermoelasticity was assumed. Constant (temperature-independent) thermal and mechanical rock properties were used in the calculations. These properties were determined by conventional laboratory testing on small intact core specimens recovered from the Stripa test site. Two-dimensional axisymmetric models were used for the full-scale experiments, and three-dimensional models for the time-scaled experiment. Highest compressive axial and tangential stresses are expected at the wall of the heater borehole. For the 3.6 kW full-scale heated experiment, maximum compressive tangential stress was predicted to be below the unconfined compressive strength of Stripa granite, while for the 5 kW experiment, the maximum was approximately equal to the compressive strength before the concentric ring of eight 1 kW peripheral heaters was activated, but would exceed that soon afterwards. Three zones of tensile thermomechanical stresses will occur in …

Evaluation of resource impact factors versus social cost estimates in determining building energy performance standard levels
In order to increase the welfare of society through the implementation of a building energy-performance standard, a method is required by which the least-cost means of obtaining the desired space conditioning of a building can be estimated. In other words, a life-cycle cost model must be developed to simulate the energy-related building-design decisions that would take place if resources were being allocated efficiently. The cost-minimizing model must incorporate technically efficient conservation strategies and fuel-conversion equipment, and the prices used must reflect the social value of the fuels and capital equipment used. This report explores the feasibility of developing a factor that could be used to adjust a design energy budget to account for the external costs associated with that energy consumption. One such factor, RIF (resource impact factor) has been proposed by ASHRAE. Though ASHRAE suggested the RIF x RUF (resource utilization factor) multiplier concept, RIF's were not explicitly defined. Weber (1978) suggested that RIF be defined as a ratio of social costs to effective market price. The basis for a RIF used in conjunction with a RUF is evaluated here and is found lacking. To fill the gap, a social-cost approach is developed that addresses the goals of both …
