Outdoor sources of indoor air pollution

Description: Conservation measures that seal a building, like storm window installation, can significantly reduce its energy requirements. These measures also protect its occupants from air pollutants having outdoor sources but amplify any harmful effects of those generated indoors. Using these Fourier series techniques and an approximation of outdoor pollution peaks by step functions, we obtained the following results: the average daily concentration indoors is the same as outdoors for any pollutant with n… more

Coal technology program. Progress report, October 1977

Description: Two blocks of Pittsburgh seam bituminous coal were pyrolyzed under reducing gas in the project in support of in situ gasification. Higher heating rates appear to reduce swelling of the block during pyrolysis, and higher final pyrolysis temperature results in lower boiling tars. Three pressurized residue carbonization tests were completed at 1100/sup 0/F and 400 psi of methane with three feed materials. Work is in progress on the fracture toughness of thick sections of steels for piping and pres… more

Use of a semiconductor laser in infrared spectroscopy

Description: A semiconductor laser has certain properties which makes its use desirable as a continuous monitor of atmospheric pollutants. Its energy output is concentrated in widely separated energy modes of very narrow bandwidths (less than 10/sup -5/ cm/sup -1/) which can be centered on one infrared absorption line of one gas. This makes the laser quite selective. The energy in each mode is typically greater than 200 ..mu.. watts, and, because of the laser's small size, its light energy can be colli… more

Distribution and abundance of submerged aquatic macrophytes in a reactor cooling reservoir

Description: Measurements of ash-free dry weight were used to characterize the effects of a heated effluent on submerged macrophytes in a reactor cooling reservoir. The species which were most abundant during the summers of 1974 and 1975 were Myriophyllum spicatum L. and Eleocharis acicularis (L.) R. and S. Examination of the vertical distribution of the shoot biomass of Myriophyllum revealed that plants in heated areas grew closer to the water surface than plants in unheated areas.

Some long-range speculations about coal. [CO/sub 2/ problems of greatly expanded use]

Description: Should the world demand for energy increase sixfold within the next 50 years, largely because the underdeveloped countries industrialize, and if half this demand is met by coal, then the estimated world recoverable resource of coal of 4 x 10/sup 12/ metric tons would last at this asymptotic level about 140 years. The carbon dioxide concentration in the atmosphere is then estimated to increase about threefold. These two eventualities may place limits on our ultimate use of coal. The risk of a CO… more
