Analysis of Tentative Seismic Design Provisions for Buildings

Analysis of Tentative Seismic Design Provisions for Buildings

Date: July 1979
Creator: Harris, James Robert; Fenves, Steven J. & Wright, Richard N.
Description: Report issued by the U.S. National Bureau of Standards discussing an analysis of seismic design provisions for buildings with three main objectives. As stated in the introduction, "The first objective was to assist the ATC in the preparation of its report. The second objective of the study was to augment the text of the published Provisions by providing a formal, consistent documentation of the text. The third objective was to provide alternate arrangements of the Provisions that would make them more readily usable by several categories of users" (p. 1). This report includes illustrations.

Analytical Standards for Trace Elements in Petroleum Products

Analytical Standards for Trace Elements in Petroleum Products

Date: October 1, 1962
Creator: Isbell, H. S.
Description: Report discussing a search conducted for stable, oil-soluble, organic compounds of metals (and other elements) for use in the spectrographic analysis of petroleum products. Compounds having suitable physical properties have been selected as standards. Methods are given for preparation of the compounds and for the spectrographic and chemical analysis of the chosen standards. Procedures are described for the preparation of stable solutions thereof in petroleum oils.

Annotated Bibliography on Soft X-ray Spectroscopy

Annotated Bibliography on Soft X-ray Spectroscopy

Date: June 29, 1962
Creator: Yakowitz, Harvey, 1939-
Description: Report presenting a bibliography of about 550 references of the soft X-ray literature since 1950 and through 1960. The emphasis is on the application of soft X-ray spectroscopy to the study of valence band electronic states in metals and alloys. Therefore, the spectral region of 25 to 800 angstroms involving ruled glass grating spectrometers is of principal interest. In addition to soft X-ray data, references on all pertinent aspects of the apparatus and experimental problems are included. Also listed separately are references of value in corroborating soft X-ray data with other results. Subject, author, X-ray band, material, and other indices are included.

An Apparatus for Measuring the Relative Wear of Sole Leathers, and the Results Obtained with Leather from Different Parts of a Hide

An Apparatus for Measuring the Relative Wear of Sole Leathers, and the Results Obtained with Leather from Different Parts of a Hide

Date: November 22, 1919
Creator: Hart, R. W.
Description: Technical paper issued by the Bureau of Standards over studies conducted on the quality of sole leather. As stated in the introduction, "the development of a simple method for quickly determining the durability of sole leather seemed desirable, and this paper discusses a laboratory apparatus designed for this purpose and also presents the results of tests made to date to determine the relative wear of leather from different parts of the hide" (p. 3). This paper includes illustrations, and photographs.

Atomic Energy Levels in Crystals

Atomic Energy Levels in Crystals

Date: February 24, 1961
Creator: Prather, John L.
Description: Report discussing discrete energy levels observed within certain crystals which are due to perturbations of energy levels of the free ion by an electrostatic field arising from the crystal lattice. The analytic procedures for determining the field from the charge configuration are given, and the resulting fields are classified according to their symmetry. After a general survey of group-theoretical ideas, the applicable groups are analyzed in detail, and characters appropriate for both integral and half-integral angular momenta of the free ion are tabulated. Text includes tabulations, equations, and matrices using Wigner and Racah coefficients.
