Thermal Conductivity of Solids At Room Temperature and Below: A Review and Compilation of the Literature

Description: From Abstract: "An extensive compilation is given of the measured values of thermal conductivity for nearly all solid materials from room temperature down to 0.02 kelvin. Experimental methods and physical phenomena are discussed in the text and coded in the tables for references for which curves are shown."

Tables of Chemical Kinetics : Homogeneous Reactions (Supplementary Tables)

Description: From Preface: "A brief description of the method used in compiling these tables and the limitation of coverage are given in the preface to Supplement 1 of the NBS Circular 510. The present volume contains information pertaining to substitution, exchange, and elimination reaction types and extends the material on these types found in NBS Monograph 34, Volume 1. The date on each page gives the year and month to which the literature had been surveyed."

BOLOVAC Systems for Measuring Electrical Quantities From 0.5 MHz Through Microwaves

Description: From Introduction: "This paper describes in some detail how Bolovac works, when its structural components are, what are the methods and steps of the procedure in its various major applications, and reasons for its advantages. The emphasis is on applications. Present status at the National Bureau of Standards relating to fabricating the most important component of the Bolovac-the bolometric disk-is briefly pointed out."

Tables of Chemical Kinetics : Homogeneous Reactions (Supplementary Tables)

Description: From Preface: "A brief description of the method used in compiling these tables and the limitation of coverage is given in the preface to Supplement 1. A description of the numbering system used is classifying reactions for the tables is given in Supplement 2. The present supplement contains information pertaining to Substitution, Exchange and Elimination reaction types. It is not complete as still more material falling groups is being prepared."

Tables of Einstein Functions: Vibrational Contributions to the Thermodynamic Functions

Description: From Introduction: "The recent acceptance by physicists and chemists of new values for the fundamental constants and the continued demand for expanded and convenient tables prompted the recomputation and preparation of this volume. The authors have tried to incorporate this work a number of the more desirable features of the above-cited works, particularly with respect to their use in calculations involving: Thermodynamic properties of gases; specific heats, electrical and thermal conductivity of solids; and molecular structure and spectroscopy of diatomic and polyatomic molecules. It is the hope of the authors that formal character of this publication will insure a more adequate notice and dissemination than was accorded the earlier works, thereaby reducing the probability of still further duplication of effort."

Tables of Electron Radial Functions and Tangents of Phase Shifts for Light Nuclei (Z=1 through 10)

Description: From Introduction: "This Monograph, supplemented by ORNL-3207 [9], should eliminate completely the need for use of approximate formulas (e.g. those of Kotani and Ross [10]). The formulation of the problem has been summarized in sec. II. This is followed in sec. III by a discussion of the methods used in numerical calculations. Sec. IV contains a detailed explanation to facilitate the use of present tables."

Mechanical Properties of Structural Materials at Low Temperatures: A Compilation From the Literature

Description: From Introduction: "The data are presented with the idea that an engineer who is making initial calculations on equipment for operation at cryogenic temperatures is more interested in obtaining quickly a definite figure that he in evaluating the experimental data given in several detailed reports on the same material. The graphs and tables presented here, consequently, represent an attempt by the authors to perform evaluation of data which have appeared in the literature and to present the design engineer with the result."

The Divergent Beam (Kossel) X-Ray Method and Its Uses in Measuring Strain Contours in an Individual Grain of Fe-3 Weight Percent Si Transformer Sheet

Description: From Abstract: "The results showed that a variable strain distribution existed in the alloy sheet at the time it was ready for insertion into a transformer core. Small applied comprehensive and tensile loads tended to rearrange this variable strain distribution but not appreciably alter the total stored elastic energy."

Ionospheric Radio Propagation

Description: From Preface: "The purpose of this book is to replace, in part, a previous publication of the National Bureau of Standards (Circular 462) with the same title. The scope of the present work has therefore been broadened to include aspects of ionospheric radio propagation which were not treated in earlier publication."

Space Groups and Lattice Complexes

Description: From Abstract: "The lattice complex is to the space group what the site is to the point group - an assemblage of symmetry-related equivalent points. The Tables list site sets and lattice complexes in standard and alternate representation. The higher the symmetry of the crystal structures is, the more useful the lattice-complex approach should be on the road to the ultimate goal their classification."

Table of Wavenumbers: Volume 2, 7000 A to 1000 mu

Description: Report discussing "A two-volume table for converting wavelengths in standard air to wavenumbers in vacuum. Wave-numbers are given to the nearest 0.001 K (cm^-1) for wavelengths from 2000 to 7000 A in volume 1, and 7000 A to 1000 m in volume II."
