Teratology studies of lewisite and sulfur mustard agents: Effects of lewisite in rats and rabbits: Final report

Description: Lewisite was administered to rats and rabbits by intragastric intubation. Maternal animals were weighed periodically, and, at necropsy (20 dg (days of gestation) in rats and 30 dg in rabbits), were examined for gross lesions of major organs and reproductive performances; live fetuses were weighed and examined for external, internal and skeletal defect. In rats, a dose level of 1.5 mg/kg did not induce toxic or teratogenic responses in maternal and fetal body weights and a significant reduction … more

Advanced combustion system for industrial boilers. Quarterly technical progress report, August 1987--October 1987

Description: The purpose of this project is to develop an advanced coal-combustion system for industrial boilers. With the new combustion system, coal could be used to replace oil and possibly gas as fuel for many industrial boilers. The advanced combustion system is comprised of several parts: (1) A new burner-design concept for coal fuels, developed from the familiar gas turbine combustor-can designs that have proven efficient, reliable, durable, and safe for the combustion of liquid fuel oils. (2) A coal… more

Development of a retrofit coal combustor for industrial applications. Technical progress report, October--December 1987: Draft

Description: During this quarter the tandem design configuration unit was tested on a low ash pulverized coal. The test results confirmed operation with strong peak-to-peak pressures and high carbon burn-out efficiencies. These configuration units were dismantled after testing with micronized coal (see third quarterly) and pulverized coal during this period. The refractory material in one of the chambers failed, probably due to improper curing during installation. Design modifications based on performance w… more

Establish Feasibility for Providing Passive Cooling With Solar Updraft and Evaporate Downdraft Chimneys. Final Report, June 15, 1984--December 31, 1987

Description: Natural draft towers can be used for cooling and ventilating structures. From an operational perspective, the downdraft evaporatively cooled tower is preferred for a dry climate. Solar chimneys, when used alone, tend to require an excessively large solar collector area when appreciable quantities of air must be moved. When used in combination with a downdraft tower, the roof and attic of buildings may assist the solar chimney and their use becomes more attractive. Both a frame building and a gr… more

Soft x-ray laser microscopy

Description: Microscopes based on soft X-ray lasers possess unique advantages in bridging the gap between high resolution electron microscopy of dehydrated, stained cells and light microscopy at comparatively low resolution of unaltered live cells. The high brightness and short pulse duration of soft X-ray lasers make them ideal for flash imaging of live specimens. The Princeton soft X-ray laser is based on a magnetically confined laser produced carbon plasma. Radiation cooling after the laser pulse produce… more

Determination of optimum electrolyte composition for molten carbonate fuel cells. Quarterly technical progress report, October--December 1987

Description: The goal of this program is the development of a molten carbonate fuel cell (MCFC) anode which is more tolerant of sulfur contaminants in the fuel than the current state-of-the-art nickel-based anode structures.
