Provisional Thermodynamic Functions for Para-Hydrogen

Description: The need for thermodynamic functions of para hydrogen, especially in compressed liquid and dense fluid states, prompts the tabulation of these provisional properties, computed by approximate methods utilizing the new PVT data of these reports. Computation and preparation of the tables is discussed under the following: Approximate Computational Methods; Correlation Methods; Discussion of Errors; and Tables of Functions.

The Solar Spectrum 2935 Å to 8770 Å : Second Revision of Rowland's Preliminary Table of Solar Spectrum Wavelengths

Description: From Abstract: "An introductory text gives a detailed description of each column of the solar ledger. Tables include counts of lines of each spectrum recorded in the identification column, leading lines in the first and second spectra, and summaries of molecules and elements present in the sun. About 73 percent of the lines are wholly or partially identified. Sixty-three elements are recorded as present."

Tables of Spectral-Line Intensities: Part 1, Arranged by Elements

Description: Abstract: "These data are presented by element in part I, and all 39,000 observed lines are given in order of wavelength in Part II." From Introduction: "In the beginning, most intensity data were reported on an arbitrary scale of 10 steps, weak lines being assigned an intensity of 1, and the strongest line intensity 10."

Towards a Tribology Information System

Description: Abstract: A workshop was held in July 985 to address the needs for a computerized tribology information and data system, as well as possible implementation schemes. The meeting was sponsored by the American Society of Mechanical Engineers, Research Committee on Tribology, the Department of Energy, Energy Conservation and Utililation Technology Division, and the National Bureau of Standards. The views of a broad sector of industry, academia, and government were obtained over a four-week period t… more
