Results are reported on adsorption of water vapor on reservoir rocks, physics of injection of water into vapor-dominated geothermal reservoirs, earth-tide effects on downhole pressures, injection optimization at the Geysers, effects of salinity in adsorption experiments, interpreting multiwell pressure data from Ohaaki, and estimation of adsorption parameters from transient experiments.

Phase transformation and cracking during RT aging of charged, high-purity Fe18Cr12Ni alloy and commerical 304 ss were examined; results show that [epsilon]* (hcp) hydride formed on Fe18Cr12Ni upon charging, and it decomposed rapidly to form first [epsilon] and then [alpha]' martensite. Morphology of fracture surfaces of Fe18Cr12Ni produced by corrosion fatigue in NaCl solutions and in hydrogen was found to be identical. Effort was made to examine the approaches and methodologies used in service life predictions and reliability analyses.

The principal objective of this research is to determine the role host petroleum-derived oils (1000[degrees]F+), as well as that of catalytically treated host oils, play when used as liquefaction solvents in coprocessing with coal. The host oils will be extensively characterized and then pretreated in a number of ways which involve catalytic reactions such as hydrogenation, hydrocracking, isomerization, and dehydrogenation. The pretreated oils will then be characterized. The effects of the host oil on coprocessing with coal will be compared to those obtained using catalytically modified heavy oils. When appropriate, model compounds will be used to study specific reactions brought about by the pretreatments. Highly dispersed iron catalysts modified by the addition of small amounts of other metals will be used to modify the chemical composition of the host oils. To date, five different pretreatment reactions have been carried out on the Amoco oil. Table 1 list some properties of this oil. Details of the reaction conditions used are given in Table 2. An objective of the pretreatment reactions is to increase hydrogen content without too significant a breakdown (cracking) of the hydrocarbon structures. Severe cracking could produce a light hydrocarbon solvent which may not be suitable for coprocessing because …

Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Dan Morales, regarding a legal question submitted for clarification: Whether the Texas Surplus Property Agency is authorized to obtain fire and casualty insurance to protect agency buildings, and related questions (RQ-53)

The SDC calorimeter will be immersed in a strong magnetic field in the endcap region because of the solenoid which supplies the SDC tracking field. This flux must be returned through the endcap region of the electromagnetic (EM) and hadronic (HAD) calorimeters. Since magnetic fields are known to induce changes in the light output of plastic scintillator, the endcap will need to be recalibrated once the solenoid is energized. In addition, gradients in the field will create nonuniformities in the calorimetric response. The ``induced constant term`` in the EM and HAD calorimeters due to the inhomogeneities induced by the magnetic field are here evaluated in order to see that SDC performance specifications are not compromised.
