Enhanced oil recovery by CO/sub 2/ foam flooding. Annual report, October 1, 1982-September 30, 1983

Description: The objective is to identify commercially available additives which are effective in reducing the mobility of carbon dioxide, CO/sub 2/, thereby improving its efficiency in the recovery of tertiary oil, and which are low enough in cost to be economically attractive. During the past year significant progress has been made in developing a commercial method of reducing the mobility of carbon dioxide in enhanced oil recovery processes. Four basic chemical structures, listed below, appear to show mo… more

TEBASCO user's guide

Description: TEBASCO is a Tandem mirror Equilibrium and BAllooning Stability COde. TEBASCO allows you to compute tandem-mirror MHD equilibria and to analyze both the flute-averaged and ballooning-mode stability of these equilibria. This stability analysis is directed toward the computation of marginal stability boundaries. Users of TEBASCO require a binary output file from the EFFI code which describes the vacuum magnetic field. In making this EFFI file the user will have defined a system of units for lengt… more

Hybrid space heating/cooling system with Trombe wall, underground venting, and assisted heat pump

Description: Our goal was to design and monitor a hybrid solar system/ground loop which automatically assists the standard, thermostatically controlled home heating/cooling system. The input from the homeowner was limited to normal thermostat operations. During the course of the project it was determined that to effectively gather data and control the various component interactions, a micro-computer based control system would also allow the HVAC system to be optimized by simple changes to software. This fle… more

S-20 photocathode research activity. Part I

Description: The goal of this activity has been to develop and implement S-20 photocathode processing techniques at Lawrence Livermore National Laboratory (LLNL) in order to study the physical properties of the photocathode films. The present work is the initial phase of a planned activity in understanding cathode fabrication techniques and the optical/electrical characterization of these films.

Small-scale hydroelectric power in Watauga County, North Carolina

Description: We have completed both the installation of the demonstration project and the assessment of the stream flows in Watauga County, North Carolina. The 17 kW, high head (178'), project on Laurel Creek in Watauga County has produced about 60,000 kWh over its first nine months of operation despite some electrical and other problems. It is currently producing 16 to 17 kW on a steady basis and is functioning as a popular site for visits by people who plan to install their own similar plants in area… more

Windows and mirrors needed for a laser-driven photoneutralizer

Description: Rough estimates of the neutral fraction obtainable from a photoneutralizer and of the power required to operate it are presented as functions of the window and mirror performance. More precise information will become available in the future.

Kinetics and Mechanism of Catalytic Hydroprocessing of Components of Coal-Derived Liquids. Sixteenth Quarterly Report, February 16, 1983-May 15, 1983.

Description: A new method of structural analysis is applied to a group of hydroliquefied coal samples. The method uses elemental analysis and NMR data to estimate the concentrations of functional groups in the samples. The samples include oil and asphaltene fractions obtained in a series of hydroliquefaction experiments, and a set of 9 fractions separated from a coal-derived oil. The structural characterization of these samples demonstrates that estimates of functional group concentrations can be used to pr… more

Refugee Act Reauthorization: Admissions and Resettlement Issues

Description: The authorization for Federal refugee resettlement assistance provided by the Refugee Act of 1980 expires Sept. 30, 1983. The 97th Congress had extended this assistance authority for one year only pending a more thorough review of the entire Refugee Act including its admissions provisions. Admissions issues that have been of interest to Congress include the role of Congress and the executive branch in establishing annual numerical limits on refugee admissions, and the interpretation of the defi… more
