A 2D electrostatic PIC code for the Mark III Hypercube

Description: We have implemented a 2D electrostastic plasma particle in cell (PIC) simulation code on the Caltech/JPL Mark IIIfp Hypercube. The code simulates plasma effects by evolving in time the trajectories of thousands to millions of charged particles subject to their self-consistent fields. Each particle`s position and velocity is advanced in time using a leap frog method for integrating Newton`s equations of motion in electric and magnetic fields. The electric field due to these moving charged partic… more

Access and Use of Information Resources in Assessing Health Risks From Chemical Exposure: Proceedings

Description: Health risk assessment is based on access to comprehensive information about potentially hazardous agents in question. Relevant information is scattered throughout the literature, and often is not readily accessible. To be useful in assessment efforts, emerging scientific findings, risk assess parameters, and associated data must be compiled and evaluated systemically. The US Environmental Protection Agency (EPA) and Oak Ridge National Laboratory (ORNL) are among the federal agencies heavily in… more

Advanced combustion system for industrial boilers. Phase 2, Quarterly technical progress report, January--March 1990

Description: During Phase I of the project, a coal injector was designed, fabricated, and tested. It is a direct replacement for the oil gun in the original equipment of a 200 hp CleaverBmoks fire-tube boiler. The system was tested at coal-firing rates in the range of 2 to 6 million Btu`s per hour, firing Upper Elkhorn No. 3 (eastern bituminous, ``UE3``) coal supplied by Energy International, Incorporated. For these tests, propane was used to preheat the boiler before initiation of coal firing. The propane … more

Advanced combustion system for industrial boilers. Phase 2, Quarterly technical progress report, October--December 1990

Description: This During this quarter, work continued on development/improvement of the low-NO{sub x} coal combustor for the boiler system. Reburning tests were conducted in the external, water-cooled test duct with a length of 15 feet using ultra fine coal with propane to reduce the NO{sub x} levels to as low as 0.295 lb-NO{sub x}/MBtu. Work also continued on design/construction of the new coal-feed system that will be used for the 100-hour demonstration test with the on-line refillable coal hopper operati… more

The advantages of a salt/bentonite backfill for Waste Isolation Pilot Plant disposal rooms

Description: This paper concludes that a 70/30 wt % salt/bentonite mixture is preferable to pure crushed salt as backfill for disposal rooms in the Waste Isolation Pilot Plant. The Waste Isolation Pilot Plant, near Carlsbad, NM, is designed to be the first mined geologic repository for the safe disposal of transuranic (TRU) radioactive waste generated by DOE defense programs since 1970. The repository is located about 655 m below the land surface in an extensive bedded salt formation. This report examines t… more

Altered phenotypes in plants transformed with chimeric tobacco peroxidase genes

Description: Peroxidases have been implicated in a variety of secondary metabolic reactions including lignification, cross-linking of cell wall polysaccharides, oxidation of indole-3-acetic acid, regulation of cell elongation, wound-healing, phenol oxidation, and pathogen defense. However, due to the many different isoenzymes and even more potential substrates, it has proven difficult to verify actual physiological roles for peroxidase. We are studying the molecular biology of the tobacco peroxidase genes, … more

An analysis of heating and cooling conservation features in commercial buildings

Description: One purpose of this study is to estimate the relationship in commercial buildings between conservation investments, fuel prices, building occupancy and building characteristics for new buildings and for existing buildings. The database is a nationwide survey of energy in commercial buildings conducted by the Energy Information Administration (EIA) in 1906. Some simple cross-tabulations indicate that conservation measures vary with building size, building age, and fuel used for building heating.… more
